BRINC's Blake Resnick takes heat for immigrant-tasing drone video – DroneDJ
Ah fame, that double-sided coin. The same month BRINC Drones founder and CEO Blake Resnick was feted as the youngest person named to the Forbes "30 Under 30 Social Impact" list, the young entrepreneur also finds himself drawing unwanted attention – and no little ire – for a resurfaced 2018 promotional video in which he hawks a border surveillance device that tases an immigrant.
A tide of both national and international press coverage has risen in the wake of the initial story in The Intercept this week. That details the Resnick-fronted video for the BRINC border control system he calls "Wall of Drones." Sporting a black blazer and a tidier version of his trademark Eraserhead redux coiffe, the teenaged Resnick describes the platform as a series of solar-powered nests from which automated drones strike out to scan the surrounding desert for potential drug or human traffickers. When it encounters suspicious types, the UAV alerts human monitors who remotely confront the suspects, demand identification the camera can relay, and decide whether authorities should be called in or not. In the video's simulated case they are – but only after the drone tases a presumably undocumented individual who refuses to cooperate.
Given the divisive debate over the treatment of undocumented immigrants – and the generally fractious state of US society in general these days – it isn't surprising that Resnick's taser-shooting drone product has sparked outrage from some quarters, and even calls to boycott BRINC.
It also doesn't help that the rather hackneyed promo really lays the border (in)security aspect especially thick ("Every year, over $100 billion of narcotics and half a million people flow through areas just like this one," Resnick says amid the dusty scrub). Also cringe-inspiring is the mesa-wandering Latino character identified as "José," who when ordered to show identification whips out a gun and – holding it sideways, gangsta-style – mocks the drone with "this is identification" before walking off and getting a back full of taser. It's just as well the Bulwer Lytton Contest does not have "product pitch video" category.
Also fueling the fire of negative reaction to both the footage and "Wall of Drones" system is the stark manner in which the device contrasts BRINC's current, carefully maintained reputation as a human startup with a big heart.
Indeed, its iconic "drones for good" business mission strives to "build technologies that save lives." According to company lore, that was a direct outgrowth of Resnick watching the horrific 2017 Mandalay Bay mass killings in Resnick's Las Vegas hometown, and create drone products capable of allowing authorities to react to and end them quickly. In addition to his work with police, fire, and first responders in developing BRINC's Lemur drone to their needs, Resnick most recently won plaudits for jumping on a plane to personally deliver the craft for use in the aftermath of Florida's Surfside condo collapse.
Both those efforts, and that reputation, aided Resnick in October to raise a cool $25 million in funding for BRINC Drones from investors like Index Ventures, Jeff Weiner, and Sam Altman.
Little wonder, then, that virtually all coverage of The Intercept discovery has been heavy with "well, look what the little angel's been hiding" schadenfreude. No little attention has been turned to the "before" shot of the younger Resnick offering an arguably unflattering comparison with his "after" status as a Good Samaritan CEO. Ditto the sight of BRINC pushing an immigrant-zapping drone system in the middle of Trump-era upheaval over the treatment of undocumented people; and today espousing beatified corporate tenants including "never build technologies to harm or kill," and "be mindful of the implications of our work – we won't build a dystopia."
Be all that as it may, it's also only fair to point out that most of the harsher scrutiny of the video has come from media that wouldn't be described as "right-leaning." It's also worth noting most coverage carefully notes Resnick's status as a Thiel Fellow, thus linking him to the man many observers – and virtually all progressives – regard as the most notorious tax-hating, Trump-boosting, let's-go-create-a-country-of-our-own-and-not-waste-money-on-the-poor Libertarian Silicon Valley billionaires around. That, it would seem, also makes Resnick guilty by association in such circles.
For his part, Resnick has clearly recognized the resurfaced tasing drone video is toxic, and risks creating real problems for himself and the company. As a result, he has made an effort to at least appear to fulfill another BRINC commandment – "be open and transparent."
Indeed, in the original Intercept article, he readily admits the entire "Wall of Drones" concept was "immature, deeply regrettable and not at all representative of the direction I have taken the company in since."
As a sign of just how serious he seems to view the revelation – and in a somewhat heady confession with the Theranos trial still underway – Resnick told the publication the entire demonstration "video was faked," and used a drone with a simulated taser to intimate the efficacy of a system that was "never fully developed, sold, or used operationally." In doing so, he seemed to apologize for "Wall of Drones" as a misguided concept from that specific era, and anathema to the kinds of products and work he's committed himself to since.
"The technology as depicted is unethical and that is one of the reasons we created a set of Values and Ethics to guide our work," Resnick told The Intercept.
Will the precociously successful and attention-grabbing CEO manage to weather the media tempest now battering him unscathed? A lot will depend on how valued BRINC's current work is to clients relative to how sternly they and others frown on its "Wall of Drones" past. Yet because of that, it's a pretty good bet efforts Resnick has made since the "Wall of Drones" video – and which have earned him such high praise – will help memories of that avowedly bad project in years gone by dissipate faster than they might have otherwise.

With a new investment of $9.7 million, Dwolla's total capital now stands at $32.5 million.
This latest investment in the real-time digital payment network was led by CME Group. The round included participation from a handful of existing investors, as well, specifically, Andreessen Horowitz, Union Square Ventures, and Village Ventures.
Writing for the Dwolla blog, CEO and Founder Ben Milne talked about how the investment will have an "immediate impact," pointing to CME Group's experience as "the world's leading and most diverse derivatives marketplace. This has led to some interesting speculation on next steps and potential future deployments of Dwolla's technology.
Recently in the news announcing the official launch of MassPay, Dwolla also was featured in an American Banker column on payment technology and wearables like Google Glass. In June, Dwolla released its Direct service to allow users to send money without requiring fully registered Dwolla accounts. The month before, the company launched Next Day Transfers, its new small business service offering that provides faster deposits (three times faster than ACH), and next-day bank withdrawals.
Founded in 2008 and headquartered in Des Moines, Iowa, Dwolla demoed its FiSync solution at FinovateSpring 2012 in San Francisco.
For alternative payments network Dwolla, life is about finding ways around the traditional, slow ACH system. In a new development today, the company announced that it is launching Next Day Transfers.
The new service aims to help SMBs replace paper checks, mitigating the estimated $13 billion spent annually on paper check operations. The Next Day Transfer service will reduce bank transfers in and out of the Dwolla network to as little as two business days.
Qualifying business, nonprofit, and government accounts can receive transfers from a bank account to their Dwolla account three times faster than a typical ACH transfer.
For all users, transfers from a Dwolla account to their financial institution may be transacted as soon as the next day.
Dwolla-to-Dwolla transfers are still instant.
To facilitate SMB's conversion to digital money transfers, the Iowa-based payments startup is also providing a Business Payments Toolkit, which aims to offer a turnkey solution to help companies switch from paper checks to Dwolla's API.
To learn more about Dwolla, check out their latest live demo from FinovateSpring 2012.

World's Largest Short Sea Car Carrier to Get Tilting Rotor Sails
Finnish technology company Norsepower has announced an agreement with global logitics and European shortsea shipping provider CLdN to install two tilting Rotor Sails on board a roll-on/roll-off car carrier.
With a cargo capacity close to 8,000 lan meters, the 2018-built MV Delphin is the largest shortsea Ro-Ro vessel in operation. The ship is operated between the UK, Ireland and Europe.
The two 35-meter-tall by 5-meter-wide Rotor Sails are expected to save the ship between 7% and 10% of its fuel consumption, depending on the route. Preparations for the insallation are currently taking place with the installation anticipated to be completed by December 2022.
Norsepower's Rotor Sails are a modernized version of the Flettner rotor, a spinning cylinder that uses the Magnus effect to harness wind power to help propel a ship. At the time of contract signing, this will be the seventh vessel to be installed with Norsepower's Rotor Sails.
"Seeing the interest grow in our tilting Rotor Sail design demonstrates how the industry is looking for proven, flexible solutions to lower greenhouse gas emissions and reduce fuel costs across a range of vessel sizes and operations," said Tuomas Riski, CEO at Norsepower.
Previous installations of Rotor Sails have taken place on board both new and existing vessels, including the tanker Timber Wolf (ex-Maersk Pelican), two passenger vessels, two Ro-Ros, and a newbuild 325,000 dwt Very Large Ore Carrier (VLOC) equipped with a record five tilting Rotor Sails. The installation onboard the Delphine will mark the third with tilting Rotor Sails, allowing the vessel to navigate on height-restricted routes.
"Norsepower's Rotor Sail installation on the MV Delphine demonstrates how the use of clean technology can modernise and evolve the performance of fleets' younger vessels to manage emissions and help to increase asset value," said Riski. "With fuel becoming increasingly expensive, making savings will also have a huge impact on commercial success. Working with CLdN and its ambitious team is an opportunity to demonstrate what our technology has to offer to continue strengthening the environmental and commercial performance of its fleet."
Gary Walker, COO Shipping, CLdN, added: "In 2021, CLdN announced it is the top performer amongst its Ro-Ro shipping peers in Northwest Europe for CO2 emissions per tonne of freight carried. By investing in technologically advanced ships and terminals, CLdN enables its customers to improve their carbon footprint and support them at the same time in making their supply chains more efficient and robust. This demand for cleaner shipping is growing and we are committed to making measurable progress. Installing two of Norsepower's Rotor Sails will maximise our fuel and emissions savings on the MV Delphine, and this pilot project will help determine how the Rotor Sail technology could be rolled out on the current CLdN fleet and our new-build vessels. We look forward to the installation and subsequent results."

Jury Rules In Favor Of Employer During COVID Quarantine Suit
Employers and their workers' compensation insurance providers were supposed to pick up the tab for workers who were required by doctors to quarantine during the pandemic. However, one case that made it to trial was officially shot down by jurors who found that the plaintiff's lack of credibility made it impossible to rule in his favor.
In the lawsuit, the plaintiff sued his employer for denial of benefits in violation of the Families First Coronavirus Relief Act. Employers were expected to provide benefits to employees who had to miss work while ill with the virus. The employee told his employer that he contracted the virus and needed to quarantine for 14 days. However, the plaintiff never saw a doctor which became apparent when his employer asked him to provide a written note saying it was okay for him to come back to work. The note made it obvious that the employee had lied, had never seen a doctor, and perhaps never had the virus.
On March 20, 2020, the plaintiff began coughing and immediately reported the symptom to his supervisor. His supervisor sent him home and asked him to complete the forms for his paid sick leave. After 14 days of quarantine, the plaintiff asked to come back to work. However, his employer required a doctor's note. The plaintiff procured a doctor's note, but the employer refused to accept it. The note only said he had quarantined for 14 days. The employer needed a note saying that he was no longer contagious. The plaintiff got another note, but by the time his COVID test had returned, his employment was terminated.
The plaintiff sought the recovery of back pay from his employer as well as punitive damages related to the retaliation for firing him after his claim. The plaintiff got neither when a discrepancy in his paid sick leave forms indicated that he was under a government-mandated quarantine as opposed to a doctor-mandated quarantine. The note was the final nail in the employee's coffin. The note indicated that the employee never saw a doctor and was thus never required to quarantine, even if he had minor symptoms of the virus.
The credibility of the plaintiff was further tested when he admitted in open court that he had lied on the forms and to his employer concerning whether or not a doctor had ordered him to quarantine for 14 days.
Meanwhile, the plaintiffs hoped to press discovery related to their employers payments to sick employees during that period of time. However, the judge refused to allow the plaintiff access to that information which may have severely harmed his case. In truth, whether or not his employer spent one dime on other employees was irrelevant to his specific claims arising from this dispute. Even if the employer denied all claims related to quarantine, this employee submitted false information, which is a crime. With his hands unclean, the jury dismissed his complaint.

Generally, many believe that the body imprisons the soul. Is it possible to view soul as a kind of real matter, which determines and controls the way our physical body exists?
RESOULNANCE tries to view the soul issue from an eastern perspective. It is an installation that put forward a possibility of visualizing the soul vibration through acupuncture points on foot.
At the same time, acupuncture points and meridians are special conduits for electrical signals. They have some distinct electrical properties, including increased conductance, reduced impedance and resistance, increased capacitance, and elevated electrical potential compared to adjacent nonacupuncture points. And some other unique properties still cannot be explained by science today. In fact, it is the key of martial arts and health regimen in Chinese culture and is closely related to "qi" in Chinese medicine. So RESOULNANCE tries to view it as a possible channel of soul. It turns the potential evoked by electrical stimulation of acupuncture point into sound, and then a unique water sound image. When the audience stares at the mirror, he will see his own face on the glass and the dynamic pattern of his own soul vibration.

Data Gaps and Market Disruptions
Dr. Steve Suppan
If the financial markets were a global plumbing system, inaccurate or incomplete financial reporting would be leaks in the system. A leak here or there wouldn't disrupt the public's understanding of the financial risks of their investments and the solvency of the major market players. But in 2008, the lack of any data reporting system for a class of unregulated financial investment products not traded on regulated exchanges was a major factor in a global financial industry crisis. Better Markets in 2018 estimated the cost of the crisis to the U.S. Main Street economy alone to be "$20+ trillion and counting."
Title VII of the Dodd Frank Wall Street Reform and Consumer Financial Protection Act of 2010 (Dodd Frank) required U.S. financial regulatory agencies to regulate these off-exchange products called "swaps" and those who trade swaps. Swaps dealers, such as JP Morgan and Goldman Sachs, create and market purportedly customized contracts to manage price risks in agricultural, energy, base and precious metal commodities, as well as financial commodities such as interest rates and foreign exchange rates. Dodd Frank required the Commodity Futures Trading Commission (CFTC) to develop rules for swaps trade data reporting and record keeping requirements in Swaps Data Repositories (SDRs).
Regulators' monitoring of the data helps them determine whether market participants are aggregating risky contracts that could bankrupt them and lead to a larger version of the $29.2 trillion of Federal Reserve Bank System emergency loans that rescued insolvent Wall Street and other global banks from 2007 to 2010. Regulatory actions to prevent default cascades throughout the industry and into non-financial firms should follow those determinations. Default cascades and extreme price volatility can be accelerated by Automated Trading Systems (ATS), an increasingly common form of trading enabled by computer algorithms.
In ATS mediated trading, one computer algorithm (a numerically expressed set of trading instructions) responding to one or more other algorithms can trigger price mini-crashes if the algorithms cannot process the information that is driving the pattern of trading. In 2016, the CFTC reported that ATS algorithms traded about 48 percent of agricultural contracts, a 10 percent increase over 2014. At that pace of acceleration, at least 60 percent of current agricultural contracts could now be traded that way. (IATP commented on an ATS rule proposed in 2015 but currently shelved.)
ATS and human mediated trades on regulated exchanges are reported in near real time to the CFTC. However, the trading of swaps and reporting of swaps trading data remain to be regulated. The first of three planned CFTC rules to govern swaps trading and trade data reporting was proposed in May. IATP responded to that proposal on October 28. Because the proposed rules are interconnected, the CFTC said it would take comments on all three rules and then issue an aggregate swaps trading rule in 2020 or 2021.
IATP's comment focused on six topic areas of the proposed rule: the impact on commodity market integrity of inaccurate and incomplete data reporting; definitions; proposed data verification procedures and requirements; record keeping requirements; SDR monitoring, screening and analyzing swap data upon Commission request; and duties of the Chief Compliance Officer (CCO). Throughout the comment letter, we responded to financial industry claims that the data reporting and record keeping requirements were too costly, technologically complex, legally burdensome and "unnecessary."
IATP urged the CFTC to consider not just what had been reported about inaccurate swaps data, but also the impact of incomplete swaps reporting on market participants, regulators and the public whose goods and services financial reporting affects. In explaining the proposed rule, one of the studies cited by the CFTC staff, concerned agricultural swaps, which IATP once characterized as "a tiny boat in the vast financial data sea." Paul E. Peterson wrote that of about 40,000 transactions he reviewed in Bank of International Settlements (BIS) data, some omitted the quantity of the agricultural commodity traded, while other transaction data lacked the price. These omissions made it impossible to calculate the value of those agricultural swaps and misrepresented the utility of using agricultural swaps to manage price risks that supposedly could not be managed on regulated exchanges.
Agricultural swaps are the smallest asset class reported to the BIS, so the data omissions could be considered quantitatively insignificant relative to omissions in reporting much larger transactions of swaps trading in interest rates. However, these agriculture swaps reporting omissions are operationally very significant. A BIS study suggested that if swaps dealers, who trade in all asset classes, neglect to report foreign exchange or interest rate swaps data comprehensively and accurately, trillions of dollars of corporate and government debt could not only be "parked" off the balance sheet, but also not be reported to regulators and interested investors as debt repackaged into tradeable assets. Regulators, investors and the public would be in the dark about the extent of financial risk in the incompletely reported trades, as most were in 2007-2008.
IATP raised concerns that the proposed rule definition for "as soon as technologically practicable" regarding the installation and operation of automated data reporting and record keeping systems required more detail to ensure compliance. We argued that the CFTC had to make clear that any swaps market dealer or participant who could afford the expense of acquiring, modifying and maintaining ATS for commercial use must be required to do so for regulatory use, including swaps reporting and recordkeeping. Otherwise the industry would continue to claim that the regulatory costs were not "technologically practicable" yet and hence "unduly burdensome." We already have good estimates of the economic carnage triggered by an unregulated and unreported swaps market.
The swaps industry, as represented by the International Swaps and Derivatives Association (ISDA), recognizes that the industry must develop consistent swaps data standards for commercial use. ISDA Chief Executive Officer and former CFTC Commissioner Scott O'Malia congratulated ISDA members on progress made on developing these standards for eventual incorporation into a fully automated "smart contract" governing trade in all asset classes.
However, the swaps industry is critical of the data verification rules proposed by the CFTC, arguing that it is legally and technically impossible for Swap Data Repositories (SDRs) to verify the accuracy of the data reported to them by all market participants. Instead, they suggest, the CFTC should continue to allow the SDRs to rely on the "trusted sources exception" of accepting as accurate and complete swaps data from the SDR trusted sources (swaps market participants whose trading history and practices are well known to the SDRs), without SDR verification and obligation to verify.
IATP found the CFTC proposed rules to be necessary and feasible for the swaps industry to implement in concert with ISDA proposed swaps data standardization. Likewise, IATP supported the proposed rule's record keeping requirements to enable the CFTC to access SDR records in near real time to analyze causes of extreme price volatility and other market events.
The CFTC asked what other data monitoring, screening and surveillance tasks that the SDRs could perform to assist the CFTC, other than the list of tasks proposed in the rule. IATP urged the CFTC to require that swaps market participants report the financial risks related to climate change of their swaps trading, just as central banks were requiring their member banks to report climate related financial risk and investors are demanding that companies report their climate related financial risks to the public. IATP suggested that the SDR climate financial risk data would be useful to the CFTC's Market Risk Advisory Committee subcommittee on climate related financial risk, to which IATP responded in a CFTC request for information.
Last, but not least, the proposed rule would weaken the explicit language of the Commodity Exchange Act (CEA) requirements concerning the duties of the CCO. CFTC Commissioner Rostin Behnam's statement about the rule's release for comment warned that the CCO's duty to "resolve conflicts of interest" between the commercial and regulatory issues of swaps markets could not be changed by regulatory language modifying those duties.
For example, the proposed language would require the CCO to "resolve conflicts of interest" only if they posed "material risk," i.e., affected a firm's financial well-being. The CCO would be vulnerable to being overruled or undermined by the CEO who would determine whether a conflict of interest presented "material risk" or not. The proposed rule would also allow the CEO to fire the CCO without any review by the firm's Board of Directors, that alone is presently authorized to dismiss the CCO. (Industry lobbyists succeeded in amending the language of the CEA to weaken the autonomy of the CCO in a House of Representatives bill (Section 111) to reauthorize the CFTC, introduced on October 29 and passed by the House agriculture committee on October 30.)
Compliance dies by a thousand little cuts to the rules, such as the cuts proposed by industry lobbyists. If the 2007-2008 swaps market crisis should have taught us anything, it is that strong compliance, not regulatory evasion, is crucial to well-functioning financial markets that serve the needs of non-financial corporations, not for-profit cooperatives and other market participants. However, it appears that the largest swaps dealers and market participants don't want to learn that lesson and are relying on another public bailout if their firms and markets go bust.
IATP Comment on Certain Swap Data Repository and Data Reporting Requirements


Isn't Turkey in the EU's customs union but not the EU?
No, Turkey is party to a bilateral EU-Turkey customs union, taking the form of a separate treaty. The EU customs union is defined in the EU treaties, most significantly Articles 28-30 of the Treaty on the Functioning of the European Union.
Good blog. Transition is unprecedented though, obviously, so it's bit strong to say UK won't be in THE EU Customs Union post-Brexit.

Nickelodeon Plans Live Action Version of Avatar: The Last Airbender!
According to Animation World Network Headline News, Nickelodeon is planning to make a live action version of Avatar: The Last Airbender.
Shyamalan To Adapt Nickelodeon's Avatar
Coming off the lackluster performance of LADY IN THE WATER, M. Night Shyamalan has signed on to write, direct and produce the live-action adaptation of Nickelodeon's popular animated series, AVATAR: THE LAST AIRBENDER, reports the trades. Paramount Pictures' MTV Films and Nick Movies, who are producing, plans to live-action adaptation into a trilogy with Shyamalan.
The film will be the first Shyamalan has directed in which he has not written an original screenplay. He previously co-wrote 1999's STUART LITTLE.
AVATAR was created by Michael DiMartino and Bryan Konietzko, Influenced by Asian art, mythology and fighting styles, the animated series is set in a world where the masters of the four nations -- Water, Earth, Fire and Air -- can manipulate their native elements. With the Fire Nation waging war, two teens free the Avatar, master of all elements and his flying bison to help restore peace to the world.
Though the Nick series previously existed, the live-action feature may have a difficult fight over using the title AVATAR. As previously announced, James Cameron will begin production on his AVATAR titled feature later in the year. Cameron has been developing his project for 12 years. Both Cameron and Nick claim they have registered the title with the Motion Picture Assn. of America.

Nickelodeon UK Timeline
Nick UK is 10 years young this September and we've got together some of the highlights and best bits of the last 10 years with our Nick timeline...
So check it out and here's to another 10 years!
Nick first started broadcasting on 1st September 1993 on Sky. We promised "to be the channel that defend the cause of kids and to make a better world for kids everywhere in this United Kingdom!"
The first program we showed was James The Cat and the only show that's still in schedule now from that first day was Clarissa Explains It All!
Other shows from that first day included Roobarb, Nickelodeon Guts, David The Gnome, Fraggle Rock and Mr Magoo...
When we started there were only THREE kids channels. Now there are TWENTY!
The first live presenter was Malcom Bird with the early morning show Dawn Patrol...
1994 saw our first live presenters, even though these were only during the school holidays! At first we came direct from Sky's studios, but we soon moved to the Trocadero Centre in the middle of London. Our first presenters were Rick Adams (that's him left), Malcolm, Lucy Alexander, Mounya and a certain Yiolanda! They were soon joined by Bogey and Rude!
1994 also saw us start our now legendary Watch Your Own Wednesday and Weekends.
The first WYOWs were hosted by boyband Take That, including Robbie Williams and Mark Owen!
We also showed the first episodes of Rugrats, Doug, Aaahh! Real Monsters on Halloween. Other shows that we were showing included Denver The Last Dinosaur, The Monkees, Ultraman, Alvin & The Chipmunks and Speed Racer!
We also launched the first ever Kids Only text service NickText.
Which is still going today!
Mounya and Yiolanda were still coming live from the Trocadero and were now starting to get tired of people calling in and asking if they were twins (for the record they're not twins, just very good mates!)
Nick also expanded, with Pirate TV, this came on for an hour after Nick had finished, where Mou and Yio took an hour of calls...
Other Nick presenters at the time include Bert The Fish, Rick Adams, James Gilby, Nigel Mitchell, Mike McClean, Sarah Cawood and Helen Chamberlain.
Show highlights included the first ever showing of our original and favourite twins Tia and Tamera in Sister Sister!
Other shows included the Nick debut of Ren & Stimpy, Duckula, Biker Mice From Mars AND The Secret World Of Alex Mack!
Nick kids were waking up to Nick AM with Mike McClean and his early morning tomfoolery, such as Guess The Gargle, Ready, Steady, Brekkie and Show Us Your Draws!
This year also saw the appearance of a Nick website, viewers of Nick AM were asked to send in their messages to Mike McClean...
1996 saw the debut of Hey Arnold, even after all this time Helga still hasn't revealed her true feelings to him...
Popping into the studio we had a pre-Angels Robbie Williams AND The Spice Girls!
This year saw us become the UK's Number One kids TV channel and we've held this position for the last SIX years!
We also started showing Sabrina The Teenage Witch, which since we started showing has been our number one for six years...
This year also saw the two fearsome twosomes start on Nick, first up Kenan & Kel and then Angry Beavers!
Mou and Yio were doing the afternoons and they were joined by Elvis, Lisa B and Matt Brown!
Elvis was one of the world's first totally computer generated presenters and used similar computer that was used to do the special effects in Jurassic Park!
As the whole World was going crazy for the World Cup in France, we made our first fully fledge series with The Renford Rejects. A show all about a hapless football team, guest stars through out it's run included the 1966 World Cup winning team, Ian Rush, Gianfranco Zola and Martin Keown.
We started giving a whole block in the mornings to Nick Jr., including UK produced Blue's Clues with Kevin!
May was a big month with our first Watch Your Own WEEK! A full FIVE days of multi-choice TV that put YOU in total control.
Other shows that we started showing included CatDog and The Wild Thornberrys.
We also started broadcasting in crystal clear digital on Sky.
We started showing Nick News! Nick News was a news show that was presented by kids that had written in. The show also had a fancy website where you could apply to be on it AND you could actually watch the show too! Not only that, but Nick News was the first ever satellite programme to win a BAFTA (very important TV award!). It didn't just win one, but two!
Big shows in '99 included Cousin Skeeter, Three Friends & Jerry and Rocket Power. We also introduced the UK to Mary-Kate and Ashley.
Simon Amstell joined the Nick Live crew and we also went on the Red Hot Lobster Tour. This basically involved a lot of gunging and kids going for the Golden Claw...
As well as all that we launched the Nick Jr and Nick Replay channels. Michael Owen won the first Kids Famer award AND the Rugrats Movie opened in UK cinemas!
We started the 21st Century with a brand new Nicktoon, SpongeBob SquarePants and by the summer he'd be presenting the Summer Splash direct from Bikini Bottom...
We also held our first-ever Sabrina September, including the episode that co-starred Britney Spears...
Thank Nick It's Friday started with Simon, Matt Brown, Mou and You offering prizes such as Your Height In Videos...
Also this is how the website looked back in 2000 too. Not very many games on it, but we did do a couple of webchats with Kenan & Kel AND Tia & Tamera!
We launched N-List and unlike any other chart at the time gave you total control of the chart. It was first presented by Kelle Bryan, and she was soon joined by our new presenter Dave Berry. Acts that aperformed on the show included Liberty X, S Club 7, Ronan Keating, Hear'Say and A1.
Sabrina won the first ever Head to Head Championship, we she's since gone on and won a every year since...
New shows to start on Nick this year included Saved By The Bell, Tucker, Brothers Garcia and The Amanda show.
We also relaunced the website, it included a load of games, plus we also streamed an ENTIRE episode of The Renford Rejects before it was broadcast! An internet first...
In 2002 Rani started waking everyone up with You're Nicked! She's now passed the alarm clock to Michelle, who is now Nicking kids every weekday morning...
We also started making kids dreams come true with Reach For The Stars with Steve Wilson. Lucky kids got to sing with A1, play football with Trevor Sinclair and give Yolly a haircut!
We launched Nicktoons TV, a WHOLE new channel for all your top Nicktoons, including new additions Jimmy Neutron and Fairly Odd Parents! We also made a toon out of a real life family in Meet The Moores!

Iranian forces bombed Iranian Kurdish opposition party headquarters and nearby refugee camps in Koya, Iraq last night, killing at least 11 people and injuring 40.
Several ballistic missiles targeted the offices of the Kurdistan Democratic Party - Iran (KDP-I) and the Democratic Party of Iranian Kurdistan (PDKI), as well as refugee camps near the offices that house thousands of civilians. The PDKI said that drones were also seen operating in the area at the time. Koya is located slightly east of Erbil, the capital of the Kurdistan Regional Government, less than 50 miles from the border with Iran.
Among the casualties were several members of both political parties, as well as civilians from the camps, including children. The KDP-I issued a statement saying that the attack targeted a meeting of the party's leadership at their headquarters. Arash Saleh, the representative of the PDKI to the United States, wrote on Twitter that "mostly civilians are the victims. We call upon foreign countries to condemn this heinous crime of Iranian regime."
The Kurdistan Regional Government expressed "concern" about the attack, but called on "all sides not to turn the Kurdistan into a region of rivalries," rather than condemning the act of Iranian aggression alone.
Iran has targeted armed Kurdish opposition groups operating in Iraq in cross-border strikes before. The latest attack represented an escalation in both the severity of the strike and the distance from Iranian territory.
The same evening, the family of Ramin Hossein Panahi, an Iranian Kurdish political prisoner who had been on death row for several months after being charged with being a member of armed opposition group Komala, announced that he had been executed.


The distance between Budapest, Hungary and Barcelona, Spain is approximately 1,507 km or 937 mi.
To reach Budapest in this distance one would set out from Barcelona bearing 57.1° or ENE and follow the great circles arc to approach Budapest bearing 69° or ENE .
Budapest has a marine west coast climate (Cfb) whereas Barcelona has a Mediterranean hot climate (Csa).
The mean temperature is 4.2 °C (7.5°F) cooler.
There are 449 fewer hours of sunlight per year in Budapest. In whichever way circa 1h 14' less per day or about 4/5 as many.
The altitude of the sun at midday is overall 6.2° lower in Budapest than in Barcelona.


Successful businesses set goals. As a business owner, it's important you take the time to set targets, review your business regularly, and communicate with your team.
While we all know the importance of goals, it's also easy to get caught up in the day-to-day activities of your business and leave those unattended. We hear you! But, if your team doesn't know and understand what it is you are trying to achieve, now is the time to sit yourself down for the next five minutes and read on.
Goals give you a long-term vision and a short-term motivation. The reason SMART goals are so important is that they make you accountable by defining measurable and time-bound factors.
R - relevant: is this goal relevant to your business objectives and values?
T - time-bound: give yourself a deadline and stick to it!
Saying "I want to get more Club signups" is not enough to actually gain more signups!
By using SMART goals you acknowledge how, what, where and when you will achieve your goal.
What is your business objective and how does this goal help you achieve it?
How does this goal align with your business' story?
#1. My goal is to drink more water.
My SMART goal is, 'I am drinking 1 liter of water every day by August 30th, 2018'.
#2. My goal is to get more email subscribers.
My SMART goal is, 'Our company will have 800 subscribers by August 30th, 2018'.
#3. My goal is to sell more wine.
My SMART goal is, 'Our winery will sell 80 bottles of wine every week by August 30th, 2018'.
Having trouble defining your goals? Try working backward. In this scenario ask yourself: "What is my ultimate goal?"
My goal is to reach 800 Wine Club subscribers by November 2018. To reach this goal, what milestones will you have to achieve? It might be opening a CRM/EDM account four months prior, building a Wine Club homepage on your website three months prior, or setting up three paid social ads pushing subscriptions two months prior, etc.
and keep them top of mind by writing them on the wall.
According to a 2015 study by Dr. Gail Matthews, 70% of participants who sent updates to their friends or co-workers reported successful goal achievements (either fully completed or more than halfway). Only 35% of participants who kept their goals to themselves reported success.
Congratulations! Now that you've got your goals signed off there's one thing you must do to ensure they don't fail!
The reason we record weekly is to create closure and growth. You can keep your goal tracking simple (such as by using paper), but we recommend going digital, with Google Docs, for example. Have each member of your team fill the results of their responsibilities/tasks on a spreadsheet the end of each week. Keep it simple!
3. How do you know if you've achieved your goals?
The success of your goal is not as black and white as yes or no. The reason we use SMART goals is so that you can qualify your results.
You currently gain 10 Wine Club subscribers each week.
Your goal is to increase your Wine Club by 30 new subscribers every week over the next 12 weeks. Your records show you fell short a total 20 subscribers over the 12 week period. This is not bad news!
When looking at your SMART goals, every cloud has a silver lining. The most important factor to remember is to have your goals in clear view so they create a sense of focus between you and your team. Celebrate your achievements and discuss your shortcomings weekly. You'll quickly notice patterns. At the end of your goal cycle, you can either set new (higher) targets or readjust the business focus.

\section{Introduction}
It is one of the basic postulates of quantum physics that
the time evolution of {\it closed} quantum systems is governed by
the Schr\"odinger equation \cite{schrodinger_equation}.
As a result for any time interval of length $\tau>0$
a state of a quantum system described by a density operator $\varrho$
is transformed according to a unitary conjugation
\begin{eqnarray}
\varrho \mapsto \varrho^\prime_\tau=U_\tau\varrho U^\dagger_\tau\,,
\end{eqnarray}
where $U_{\tau}=e^{-\frac{i}{\hbar}\tau H}$, $H$ is the (for simplicity
time-independent) Hamiltonian of the system and $\hbar$ is the Planck constant.
Moreover, it is natural to assume that
$U_\tau=U_t U_s$, where $\tau=t+s$ and $t,s>0$ are
arbitrary durations of short time intervals that sum up to
the whole time interval $\tau$. However, if the system is open (interacting with
its environment) such simple division of time evolution into incremental time steps does not necessarily
possess a clear meaning. It is a relatively recent discovery
\cite{wolf_indivisible} that certain non-unitary quantum evolutions
are indivisible into shorter ones. In order to make this statement precise
let us introduce a mathematical framework modelling open system dynamics
over finite time intervals.

Let us assume that initially the system and its environment
are not correlated, so that that the combined system-environment
initial state can be described as $\varrho\otimes\xi $
(such an assumption is quintessential in order to
preserve linearity of the dynamics - see eg Ref.
\cite{stelmachovic_buzek} and references therein).
Then the evolution of the joint system-environment state is governed
by the Schr\"odinger equation and the state transformation over
the time interval $[0,\tau]$ is described by a map
\begin{eqnarray}
\varrho\mapsto{\cal E}_\tau[\varrho]={\rm tr}_{\rm env}[\tilde{U}_\tau\varrho\otimes\xi \tilde{U}_\tau^\dagger]\,,
\end{eqnarray}
where $\xi$ is the initial state of the environment and
${\rm tr}_{\rm env}$ denotes the partial trace over the environmental
degrees of freedom and $\tilde{U}_\tau$ is a unitary transformation describing
both the system and the environment.
Abstracted mathematical properties of ${\cal E}_\tau$
guaranteeing the existence of such model for ${\cal E}_\tau$ are
linearity (${\cal E}(X+\lambda Y)={\cal E}(X)+\lambda{\cal E}(Y)$),
complete positivity (positivity of ${\cal E}_\tau\otimes{\cal I}_d$ for all $d$) and
trace-preservation ($\tr{{\cal E}_\tau[X]}=\tr{X}$).
This result is known as the  \emph{Stinespring representation theorem}
\cite{stinespring} and the maps ${\cal E}_\tau$ with such properties we call
\emph{quantum channels} (see for example \cite{heinosaari_qbook}).

We say that a quantum channel ${\cal E}$ is divisible if ${\cal E}={\cal E}_1\circ{\cal E}_2$,
where ${\cal E}_1,{\cal E}_2$ are both non-unitary quantum channels. If this
is not the case, then we say the channel is indivisible.
According to this definition unitary channels are indivisible. This
may sound quite counterintuitive, especially,  if we recall how
unitary operations are decomposed into gates in quantum computation \cite{nielsen2000}.
Indeed the gate  decomposition
is the crucial tool in the analysis of quantum complexity.
But let us stress a difference between the decomposition and the divisibility
of channels. The primary task of the decomposition is to simplify the
implementation of a multipartite quantum channel by means of
elementary gates, thus, the decomposability captures
the complexity of the process expressed in terms of number of uses of elementary gates.
On the other side, the divisibility
addresses more fundamental question whether a given process can be understood
as a sequential concatenation of processes. If not, then it is natural
to ask how to simulate such quantum channels, in particular by means
of some "continuous" time evolution.

Dynamics of open quantum systems is modelled by so-called master
equations that are usually derived under the assumption of Markovianity
\cite{davies_book,breuer_book}.
Mathematically this means that one parametric set of channels
${\cal E}_t$, being the solution of Markovian master equation (equivalently
Lindblad master equation), satisfies
the semigroup property ${\cal E}_{s}\circ{\cal E}_t={\cal E}_{s+t}$ for all $s,t\geq 0$
and the initialization condition $\lim_{t\to 0}{\cal E}_{t}={\cal I}$. Formally
we can write ${\cal E}_t=e^{{\cal L} t}$, where ${\cal L}$ is known as the Lindbladian.
We say a channel ${\cal E}$ is Markovian if there exist the Lindbladian ${\cal L}$
and time $\tau$ such that ${\cal E}=e^{{\cal L}\tau}$. Otherwise, the channel
is called non-Markovian. Let us note that all indivisible channels
are non-Markovian, but there are divisible non-Markovian channels
\cite{wolf_indivisible,wolf_snapshot}.

Simple collision models, in which the system's evolution
is modelled via a sequence of (weak) interactions of the system
with sequentially selected particles from the environment,
provide a natural playground for simulations of quantum dynamics.
It is known (see for instance Refs. \cite{ziman_collision,ziman_chapter}) that
these models can approximate (with arbitrary precision)
any evolution governed by a Lindblad master equation \cite{lindblad,gorini},
i.e. implement any Markovian quantum channel. Our aim in this paper
is to investigate whether a general quantum channel (in particular
an indivisible one) can be simulated in the framework
of simple collision models. Let us note that a related
collision model was studied in Ref. \cite{giovannetti2012}, where
the authors derived master equations for a family of correlated Markovian
evolutions.

This paper is structured as follows. In Section II, we define the
framework of collision models and we introduce the concept
of stroboscopic simulations. In Section III, we design
a collision model for implementation of {\it all} indivisible
qubit channels. Finally, we discuss our results and present conclusions of our investigation
in Section IV.

\section{Simple collision model}
By a collision model of a specific system dynamics we understand
a sequence of interactions (collisions) between the system and
particles from the environment. Essential property of the model considered
in this paper is that each particle of the environment interacts with the system at most
once, while the environment particles do not interact between themselves.
More formally, let
$U_j$ be a bi-partite unitary operator describing an individual collision between the system particle and the $j$-th particle of the environment.
Collision model is a concatenation of unitary channels $U_10.03 U_n$ (see Fig.~\ref{collision_model}).
Let us denote by $\omega_n$ the initial state of the environment
composed of $n$ particles and by $\varrho$ the initial state
of the system.

Suppose $\varrho\to\varrho_t={\cal E}_t(\varrho)$ is a solution of
some Lindblad master equation. The question we will like to answer is ``How to simulate
the process ${\cal E}_t$ in the framework of a collision model?'' Assume $U_{\delta}$
and $\xi$ determine the Stinespring dilation of ${\cal E}_{\delta}$.
Then the sequence of concatenations of $U_\delta$ applied in each
step jointly on the system and a ``fresh'' particle from the environment
in the state $\xi$,  results in a discrete evolution
\begin{eqnarray}
&&\varrho\mapsto\varrho_n={\cal E}_{\delta}^n(\varrho)\nonumber\\
&&=
{\rm tr}_{\rm env}[(U_1\cdots U_n)(\varrho
\otimes\xi^{\otimes n}) (U_1\cdots U_n)^\dagger]\,,
\end{eqnarray}
where $U_j=U_\delta\otimes I_{\overline{j}}$ and $I_{\overline{j}}$
denote the identity operator on all particles of the environment
but the $j$th one. As a result the described
collision model \emph{stroboscopically simulates} the continuous Markovian
evolution, i.e. for all $\delta>0$ we have ${\cal E}_t\approx{\cal E}_{\delta}^n$
with $n=[t/\delta]$ ($[x]$ denotes the nearest integer to $x$).
The parameter $\delta$ determines the quality of the (stroboscopic)
approximation of the time-continuous (Markovian) dynamics ${\cal E}_t$
for $t\geq 0$.

It was shown in \cite{ziman_deco} that if $U$ is a controlled unitary
operator, then the sequence of collisions simulates pure decoherence process,
in which the diagonal elements of density operators
(with respect to the so-called decoherence basis) are preserved
while the off-diagonal ones vanish exponentially. Setting $U$
to be the partial SWAP interaction \cite{ziman_homo,scarani_thermo} the system
exponentially converges to the original state of the particles
in the reservoir. The information about the original state of the
system is diluted into the correlations among environmental particles.
Because of these features the process is called quantum homogenization and
represents a quantum information analogue of thermalization process, in which
the temperature is replaced by the concept of quantum state.

In both examples described above it is assumed that the initial state of the
reservoir is factorized, i.e. $\omega_n=\xi^{\otimes n}$. In this factorized
setting, the channel ${\cal E}_1$ is called a \emph{generating channel}
of the collision process. Indeed, if this is
the case, then the
induced discrete dynamics ${\cal E}_n\equiv{\cal E}_1^n$ fulfills the conditions
of a discrete semigroup,
i.e. ${\cal E}_n\circ{\cal E}_m={\cal E}_{n+m}$ for all positive integers $n,m$. Without
loss of generality we may set ${\cal E}_0={\cal I}$.  It is important
to stress that such semigroup feature does not guarantee that
the discrete dynamics stroboscopically approximates some
Markovian continuous-time evolution. In other words, the generated
channels ${\cal E}_n$ are not necessarily Markovian.
For instance, by definition indivisible channels ${\cal E}_{\rm indivisible}$ can
be elements of a discrete semigroup only as the generating channels, i.e.
${\cal E}_{\rm indivisible}={\cal E}_1$.

But what if a general
initial state of the environment is allowed? Could we then find
a way how to stroboscopically simulate (using the collision model)
a continuous-time evolution leading to an arbitrary quantum channel?

Let us formulate the problem: We say ${\cal E}$ is a
\emph{stroboscopically simulated channel} if for every $n$
there exists a bipartite interaction $U$
(between the system and a specific particle from the environment )
and an initial state $\omega_n$ of the environment
such that ${\cal E}_n\equiv{\cal E}$, where
$$
{\cal E}_n(\varrho)=
{\rm tr}_{\rm env}[(U_1\cdots U_n)(\varrho\otimes\omega_n)
(U_1\cdots U_n)^\dagger]\,,
$$
and $U_j=U\otimes I_{\overline{j}}$. If the channel can be
approximated in the introduced sense, then
the collision models reveal the elementary features of Markovian
dynamics even for non-Markovian channels. In particular,
the process can be realized in arbitrarily small (non-unitary)
steps although the steps themselves are not described by valid
channels. Our aim is to address the question which channels
can be stroboscopically simulated? In what follows we will focus
on implementation of indivisible quantum channels, which are, intuitively,
the most non-Markovian examples of quantum evolutions.

\section{Stroboscopic simulation of indivisible qubit channels}
The existence of indivisible channels was observed for the
first time in Ref.~\cite{wolf_indivisible}, where the authors
analyzed in detail qubit channels. In particular,
they found that indivisible qubit channels are unitarily equivalent
to the subclass of Pauli channels
\begin{eqnarray}
\label{eq:indivisible_qubit_family}
{\cal E}(\varrho)=q_x\sigma_x\varrho\sigma_x+
q_y\sigma_y\varrho\sigma_y+q_z\sigma_z\varrho\sigma_z\,
\end{eqnarray}
where $q_x,q_y,q_z$ are positive ($q_xq_yq_z\neq 0$)
and $q_x+q_y+q_z=1$. For instance, the choice $q_x=q_y=q_z=1/3$
defines the best quantum approximation ${\cal E}_{\rm NOT}$
of the universal quantum NOT gate for a qubit ${\cal F}_{\rm NOT}:\varrho\mapsto
(I-\varrho)$ \cite{buzek_not, martini}. The question is: how to simulate
stroboscopically some continuous time dynamics leading to these channels?

Suppose environment is composed of three-dimensional quantum systems
(qutrits). Then one of the possible dilations for indivisible qubit
channels is the following:
${\cal E}(\varrho)=
{\rm tr}_{\rm env}[C\varrho\otimes\omega C^\dagger]$, where
$C=\sigma_x\otimes\ket{x}\bra{x}+\sigma_y\otimes\ket{y}\bra{y}+
\sigma_z\otimes\ket{z}\bra{z}$ is a controlled unitary interaction
and $\omega$ satisfies the conditions $\bra{k}\omega\ket{k}=q_k$
for $k=x,y,z$. We assume that $\ket{x},\ket{y},\ket{z}$ form
an orthonormal basis of the qutrit's Hilbert space. Let us stress
that $C$ is not only unitary, but also Hermitian. Therefore
$U_\eta=e^{i\eta C}=\cos\eta I+i\sin\eta C$ defines a family
of interactions. Moreover, each member of this family is
a controlled-U operator, $U_\eta=\sum_k e^{i\eta \sigma_k}
\otimes\ket{k}\bra{k}$.

Consider a collision model generated by collisions $U_\eta$.
The concatenation of $n$ such collisions
implements a global (system plus environment) unitary transformation
\begin{eqnarray}
U_{\eta,1}\cdots U_{\eta,n}=\sum_k \exp[i n\eta \sigma_k]
\otimes\ket{k^{\otimes n}}\bra{k^{\otimes n}}\,.
\end{eqnarray}
Suppose $\omega_n$ is the initial state of the environment composed of $n$ qutrits
such that $\bra{k^{\otimes n}}\omega_n\ket{k^{\otimes n}}=q_k$.
After $n$th collision the system evolution reads
\begin{eqnarray}
\nonumber
{\cal E}_n(\varrho)&=&
{\rm tr}_{\rm env} [(U_{\eta,1}\cdots U_{\eta,n})(\varrho\otimes\omega_n)
(U_{\eta,1}\cdots U_{\eta,n})^\dagger]\\
\nonumber &=&\sum_k q_k \exp[in\eta\sigma_k]\,\varrho\, \exp[-in\eta\sigma_x]\,,
\end{eqnarray}
hence setting the strength of the interaction $\eta=\pi/(2n)$ the
resulting collision model simulates the implementation of
any indivisible qubit channel in $n$ steps.

\subsection{Evaluation of $\norm{{\cal E}_{j+1}-{\cal E}_j}$}
In this Section we will show that for the considered
collision model the individual collisions
induce arbitrarily small disturbances of the system.
Assume $n$ is fixed, i.e. $\eta=\pi/(2n)$.
After $j$th interaction the state of the system undergoes
the transformation
\begin{eqnarray}
\nonumber
{\cal E}_j(\varrho)&=&\sum_k q_k \exp[i\pi\frac{j}{2n}\sigma_k]\,\varrho\,
\exp[-i\pi\frac{j}{2n}\sigma_k]\\
\nonumber
&=&\cos^2(\frac{j\pi}{2n}) \varrho+
\sin^2(\frac{j\pi}{2n})\sum_k q_k\sigma_k\varrho\sigma_k
\nonumber\\
&&+\frac{i}{2}\sin(\frac{j\pi}{n})\sum_k q_k[\sigma_k,\varrho]\,,
\end{eqnarray}
where $[A,B]=AB-BA$ is the commutator of operators $A,B$.
Let us denote by ${\cal E}$ the target quantum channel, i.e.
${\cal E}={\cal E}_n$ (we fix $\eta=\pi/(2n)$) and
define ${\cal F}(\cdot)=[F,\cdot]$ with $F=i\sum_k q_k\sigma_k$.
Then the distance between two subsequent steps equals
\begin{eqnarray}
\Delta&=&\norm{{\cal E}_{j+1}-{\cal E}_j}=
\norm{
C_{j+1}({\cal I}-{\cal E})+D_{j+1}{\cal F}}\,,
\end{eqnarray}
where
\begin{eqnarray}
C_{j+1}&=&\cos^2\frac{(j+1)\pi}{2n}-\cos^2\frac{j\pi}{2n}\nonumber\\
&=&\frac{1}{2}\left(\cos\frac{(j+1)\pi}{n}-\cos\frac{j\pi}{n}\right)\,,\\
D_{j+1}&=&\frac{1}{2}\left(\sin\frac{(j+1)\pi}{n}-\sin\frac{j\pi}{n}\right)\,.
\end{eqnarray}
Let us note that the norm we have in mind here is the completely
bounded norm (see for instance \cite{paulsen2003}), namely,
$$
\norm{{\cal A}}=\sup_{n,X:||X||_1=1}||({\cal A}\otimes{\cal I}_n)(X)||_1\,,
$$
where $||\cdot||_1={\rm tr}|\,\cdot\,|$.

Using the identities $\cos^2\alpha=(1+\cos{2\alpha})/2$,
$\cos\alpha-\cos\beta=-2\sin(\frac{\alpha+\beta}{2})
\sin(\frac{\alpha-\beta}{2})$, and
$\sin\alpha-\sin\beta=2\sin(\frac{\alpha-\beta}{2})
\cos(\frac{\alpha+\beta}{2})$
we get
\begin{eqnarray}
C_{j+1}&=&-\sin\frac{(2j+1)\pi}{n}\sin\frac{\pi}{n}\,,\\
D_{j+1}&=&\cos\frac{(2j+1)\pi}{n}\sin\frac{\pi}{n}\,.
\end{eqnarray}
This allows us to conclude that the distance is bounded as follows:
\begin{eqnarray}
\nonumber
\Delta&\leq&
|C_{j+1}|\cdot\norm{{\cal I}-{\cal E}}+|D_{j+1}|\cdot\norm{{\cal F}}\\
\nonumber
&\leq& \sin\frac{\pi}{n}\left(
\left|\sin\frac{(2j+1)\pi}{n}\right| \cdot\norm{{\cal I}-{\cal E}}+\left|\cos\frac{(2j+1)\pi}{n}\right|\cdot\norm{{\cal F}}\right)\\
&\leq& K\sin\frac{\pi}{n}\quad(\,\longrightarrow 0\quad {\rm for\ }n\to\infty)\,,
\end{eqnarray}
where $K\leq\norm{{\cal I}-{\cal E}}+\norm{{\cal F}}\leq 2+\norm{{\cal F}}<\infty$,
because for channels $\norm{{\cal E}}=1$ and $\norm{{\cal F}}<\infty$.
In fact, as shown in Ref. \cite{paulsen2003} for any linear qubit map
$\norm{{\cal A}}\leq 2\sqrt{2} \sup_{\norm{X}_1=1} \norm{{\cal A}(X)}_1$, hence,
$\norm{F}\leq 2\sqrt{2} \sup_{\norm{X}_1=1}\norm{FX-XF}_1\leq
4\sqrt{2}\frac{\norm{FX}_1}{\norm{X}_1}\leq 4\sqrt{2}\norm{F}$,
where the relations $\norm{FX}_1\leq \norm{F}\cdot\norm{X}_1$
and $\norm{F}=\sup_\psi \norm{F\psi}/\norm{\psi}\leq 2$ were used. That is,
$K\leq 2+8\sqrt{2}$, which allows us to
conclude that the system's changes in individual steps
can be made arbitrarily small as $n$ goes to infinity.
Therefore, in this limit the evolution is continuous.

\subsection{Master equation}
Replacing the integer parameter $j$ in the expression for ${\cal E}_j$
by a continuous parameter $t$ we formally define a one-parametric
set of channels
$$
{\cal E}_t={\cal E}+\cos^2(\alpha t)({\cal I}-{\cal E})+\sin(\alpha t)\cos(\alpha t){\cal F}\,,
$$
where $\alpha=\pi/(2n)$ and linear maps ${\cal E},{\cal F}$ are defined in the
previous paragraph. Let us note that ${\cal E}_t$ form the same set of channels
irrelevant of the value of $\alpha$. Moreover, this one-parametric set
of channels is continuous in $t$ and ${\cal E}_0={\cal I}$. A collision model
(determined by the value of $\alpha$) stroboscopically
simulates continuous-time quantum evolution given by ${\cal E}_t$, where
different values of $\alpha$ define the quality of the simulation.
In this section we will derive the master equation generating ${\cal E}_t$.

Formally, the evolution of density operators is generated by
the first order differential equation
\begin{eqnarray}
\frac{d\varrho_t}{dt}=\frac{d{\cal E}_t}{dt}{\cal E}_t^{-1}(\varrho_t)\equiv
{\cal L}_t(\varrho_t)\,,
\end{eqnarray}
where
\begin{eqnarray}
{\cal L}_t(X)&=&
\frac{i}{\hbar}\sum_j h_j [X,\sigma_j]+\frac{1}{2}
\sum_{j,k}c_{jk}([\sigma_j,X\sigma_k]\nonumber\\
&&+[\sigma_jX,\sigma_k])
\end{eqnarray}
is the generator of the dynamics \cite{lindblad,gorini}.
Any such generator defines
a dynamics which is tracepreserving and if (time-dependent coefficients)
$h_j,c_{jk}$ are real, then also the hermiticity of operators is
preserved. If these parameters are time-independent (${\cal L}_t={\cal L}$)
and matrix composed of entries $c_{jk}$ is positive, then the generated
dynamics is also completely positive and Markovian. In such case
we can write ${\cal E}_t=e^{{\cal L} t}$ and ${\cal L}$ is the Lindbladian.

For sake of simplicity let us illustrate the
derivation of the driving master equation (${\cal L}_t$) for the case of
the target channel ${\cal E}={\cal E}_{\rm NOT}$. This channel transforms
the Bloch vector $\vec{r}$ into $\vec{r}^\prime=-\vec{r}/3$, hence,
implements a Bloch ball (shrinking) inversion. In this case the map
${\cal F}$ induces the Bloch vector transformation
$\vec{r}\to\vec{u}\times\vec{r}$ with $\vec{u}=(1/3,1/3,1/3)$.
Let us stress that ${\cal F}(I)=O$, hence, the map is not
trace-preserving and maps any operator into a traceless one.

In the Bloch sphere parametrization the channels take the form
of an affine $4\times 4$ matrix. Define $3\times 3$ matrices
\begin{eqnarray}
I&=&\left(
\begin{array}{ccc}
1 & 0 & 0\\
0 & 1 & 0\\
0 & 0 & 1
\end{array}\right)\,,\quad
A=\left(
\begin{array}{ccc}
0 & -1 & 1\\
1 & 0 & -1\\
-1 & 1 & 0
\end{array}\right)\,,
\nonumber\\
S&=&\left(
\begin{array}{ccc}
0 & 1 & 1\\
1 & 0 & 1\\
1 & 1 & 0
\end{array}\right)\,.
\end{eqnarray}
Then the one-parametric dynamics is given by the following
$4\times 4$ matrix
$$
{\cal E}_t=
\left(\begin{array}{cc}
1 & 0 \qquad 0 \qquad 0 \\
\vec{0} & x(t)I+a(t)A
\end{array}\right)\,,
$$
where $x(t)=\frac{1}{3}(4\cos^2\alpha t -1)$
and $a(t)=\frac{1}{6}\sin(2\alpha t)$.
A direct calculation gives
\begin{eqnarray}
\frac{d{\cal E}_t}{dt}=\frac{1}{3}\alpha
\left(\begin{array}{cc}
0 & 0\qquad 0 \qquad 0 \\
\vec{0} & 4\sin (2\alpha t) I+\cos (2\alpha t) A \\
\end{array}\right)\,,
\end{eqnarray}
and
\begin{eqnarray}
{\cal E}_t^{-1}=
\left(\begin{array}{cc}
1 & 0\qquad 0 \qquad 0 \\
\vec{0} & \frac{1}{3x(t)}I-\frac{a(t)}{\det{{\cal E}_t}}
[x(t)A-a(t)S] \\
\end{array}\right)\,,
\end{eqnarray}
where $\det{{\cal E}_t}=3x(t)[a(t)^2+x(t)^2]$. Thus, for the generator
we get
\begin{eqnarray}
{\cal L}_t=\frac{d{\cal E}_t}{dt}{\cal E}_t^{-1}=
\left(\begin{array}{cc}
0 & 0\qquad 0 \qquad 0 \\
\vec{0} & b(t)I+c(t)A+d(t)S \\
\end{array}\right)\,,
\end{eqnarray}
with
\begin{eqnarray}
b(t)&=& \frac{2}{9}a(t)\left[12\alpha+\frac{1}{a(t)^2+x(t)^2}\right]\,,\\
c(t)&=& \frac{1}{9x(t)}\left[\frac{\alpha (3x(t)-1)}{2}-
\frac{a(t)[3x(t)+a(t)]}{x(t)[a(t)^2+x(t)^2]}\right]\,,\nonumber\\
\\
d(t)&=& \frac{a(t)[3a(t)-x(t)]}{9x(t)[a(t)^2+x(t)^2]}\,.
\end{eqnarray}
Using the methods and formulas described in Ref.~\cite{ziman_chapter}
we obtain the non-Markovian master equation in the operator form
\begin{eqnarray}
\frac{d\varrho_t}{dt}&=&-\frac{ic(t)}{2\hbar}[\varrho_t,H]
-\frac{b(t)}{2}(\sum_j \sigma_j\varrho_t\sigma_j - 3\varrho_t)\nonumber\\
&&+d(t)\sum_{j\neq k}{\sigma_j\varrho_t\sigma_k}\,,
\end{eqnarray}
where $H=\sigma_x+\sigma_y+\sigma_z$.
The time dynamics induced by the collision model is illustrated
in Fig.~\ref{fig:NOT_collision}.

\section{Conclusions}
In this paper we open
the question of continuous time (stroboscopic) simulation of
quantum channels within simple collision models, i.e. via a sequence
of interactions of the system with particles forming the environment.
Using the environment composed of three-dimensional quantum
particles we design a collision model simulating arbitrary indivisible
qubit channel. Indivisible channels could be coined as the most
non-Markovian ones if one quantifies the \emph{Markovianity of a channel}
${\cal E}$ as the maximal number ($n$) of non-unitary channels
${\cal E}_1,0.03,{\cal E}_n$ such that ${\cal E}={\cal E}_1\cdots{\cal E}_n$. The smaller the
number, the more non-Markovian is the channel. Let us stress that
there are several recent proposals for measures of Markovianity
of continuous time evolutions
\cite{breuer2009_nonmarkovianity_measure,rivas2010,{usha_devi_2011}}.
These measures can be applied not only to the derived master equation for
implementation of ${\cal E}_{\rm NOT}$, but can be also
modified to the settings of discrete time evolutions, which are
naturally generated by simple collision models. However, a more
detailed analysis along these lines goes beyond the scope
of this paper.

Another important point we want to stress is the necessity
of initial correlations between the particles of the
reservoir, which are introducing the memory mechanism present in
any non-Markovian evolution. It is of interest to understand
whether there is some deeper relation between the correlation
structure of $\omega_n$ and memory features of the system's
dynamics (Markovianity). In order to answer this question
one needs to understand the ambiguity of the stroboscopic simulation.
For example, each convex decomposition into unitary channels
induces a different collision model (as described in the previous Section)
for the same channel ${\cal E}$. However, for this class of collision models
there is no qualitative difference neither in the initial states, nor
in the derived evolutions. In the considered collision model,
the correlations are relatively
strong and all particles forming the environment are mutually pairwise
correlated, but it could happen that there are qualitatively different
collision models for which the structure of correlations is completely
different, especially, it could be that particles entering the $j$th
and the $k$th collision are initially uncorrelated if $|j-k|$ is
sufficiently large.

In summary, we have introduced the problem of stroboscopic simulations of a general
quantum channels. In this paper we reported the case study of qubit
indivisible channels and we designed a collision model for implementation
of any channel from the family of random unitary channels
(see \ref{A}). Since indivisible channels are the most non-Markovian,
it is natural to conjecture that any channel can be simulated
in the stroboscopic manner. In fact, it was shown in
\cite{wolf_indivisible} that
nonunital qubit channels are infinitesimal divisible and
can be approximated by a concatenation of Markovian
channels that can be stroboscopically simulated by
factorized states of the environment. Moreover, since unital qubit channels are necessarily
random unitary and  for them we have an explicit collision model
(irrelevant of their Markovianity), we may conclude that collision
models can stroboscopically approximate any qubit channel.
We believe the considered collision model
deserves further investigation that finally results in a better understanding
of non-Markovian features of general continuous time quantum evolutions
and implementations of non-Markovian quantum channels.

I can certainly see that French society is regulated more so than the UK. I find the French to be very conservative, with a love of/for tradition and heritage. Change is slow and requires much discussion.
These things smack you in the face daily in the most mundane of circumstances.
I've done PBP four times and been to Semaine Federale since 2008. It seems to me that the respect accorded to those on committees makes these large events possible. But the detailed large scale planning of those events makes them a bit inflexible. Anything that we can do to flow around problems helps.
Nothing is paid for upfront, so the only point of contact we need are the control check ins. But in practical terms there is nowhere else to eat at 4am.
Learn how to stop your tail light flashing ? I must remember to spend hours practicing this?
It is also contrary to French law. The single file suggestion may relate to the law that forbids cycling two abreast in the dark, but I thought that was the sort of French regulation w that got ignored.
Current French law is that you may have a blinking rearlight if you also have one that doesn't blink.
I might have to rethink my plans to do the ride. I fecking hate flashing lights with a noisy self righteous passion.
At least I could be right in more than just my own universe when they were still banned.
Speaking of laws to be obeyed, and introducing THAT subject (you know, the one we've ALL been waiting for) hi-viz vests.
On PBP 2011, I saw, with my very own fatigue-free eyes, riders being pulled over (and maybe even fined) for, as it transpired, not wearing hi-viz. I wasn't wearing mine at the time either, because I didn't want to stop to put it on, but quickly rectified that.
It was still light but fading... dusk as they say I guess.
I am rather hoping that ACP keep the rule in place, despite the law. Made the ride rather more pleasant and the effect of the red ribbon stretching for miles ahead of you on night one would be less if rear lights were flashing.
I only saw a couple of transgressions of it in 2011 (both RUSA riders coincidentally!).
Discussions like this make me wonder if I can get into shape for PBP next year. Imagine the potential for befuddlement caused by am American who rides like a Brit.
I was pulled over by one of the chaps on scooters. It was early in the morning, just before sunrise but quite light, and it had got a bit cold, so I put my see-through race-cape (with reflective strips) on top of my PBP gilet. No question of a fine, but he politely asked me to rearrange my layers.
There are some vastly experienced RUSA folk contributing to that thread, along with several numpties. True about the passport thing - at 2011 Texas Rando Stampede, one of the riders was out of his US state for the first time, let alone owning a passport.
It is just very easy to take the piss when some folk essentially recommend an approach that basically isolates them from the joys of riding PBP as much as is physically possible. If you ignore the controls to save time, sleep in pre-booked rooms, avoid opportunities to socialise with riders from round the world and minimise mixing with the locals just to save time off the bike, why bother going to France? Ride a 1200 in your own country and never get out of your comfort zone. Many RUSA members now avoid riding PBP in favour of their own events and it isn't surprising if your intent is to eliminate any differences from your regular events.
A sub-60 hour PBP finish is admirably quick (and might be worth sacrificing these other aspects for) but everybody gets the same medal. There is no certainty that a rider will be able to come back in 4 years' time to do PBP again and some opportunities will never be repeated, no matter how many times you ride the event.
Last year one of those scam e-mails saying "Help! I am stuck in $ABROAD! Send money!" was doing the rounds, purporting to come from my mate Al. In Manila. We were swiftly reassured that he hadn't lost his passport in Manila, as he hadn't got one.
Mind you, he's in the process of acquiring Canadian citizenship so I suppose he'll have to get one soon.
Personally, I'd prefer a Monday start and Friday finish as it's simpler from a holiday time booking perspective and you can do it with 5 days off as opposed to 6, but I wouldn't like to be someone who has booked complicated or long distance travel arrangements on the assumption that they would finish sometime on Thursday and travel home the next day.
I imagine there will be a lot of discussion in anticipation of the decision in 10 days' time. Separate thread, Mr Mod?
Easy either way, although I had said I'd be home Friday afternoon. Being well prepared I've already booked my hotels. Being even better prepared I booked flexible rates.
I would like to see an email thread resulting from 500 UK riders having to travel to Louisiana to do a 1200km ride - pretty certain there would be some howlers..
No offence but really, why would I go to the southern United States to ride a bike?
Just as well other folk do not take that view with regards to travelling to UK for LEL or even France for PBP.
I quite fancy riding in the USA, Australia, Korea, Japan and a few other places. Just as well folk in UK don't say "why would I go to the South West (or wherever) to ride a bike?"
Some people did for the Natchez Trace 1500.
There is a magical roadway to the west. It is a strip of smooth two-lane blacktop 444 miles long. It is bordered by trees, fields, rivers, streams and many sights of historical significance. Perhaps its most unique feature is that it is a National Historical Park maintained and operated with Federal funding. It is the eighth most visited National Park in the country. Its northern terminus abuts Nashville, Tennessee while the southernmost part is in Natchez, Mississippi. The main purpose is recreation therefore no commercial vehicles are allowed. The speed limit is never higher than 50 mph, which discourages vehicles from using it for transportation. It is a perfect environment for the cyclist. Neither hilly nor flat, slightly winding, and, impeccably maintained. The roadway is known as the Natchez Trace Parkway. Folks residing in the proximity of it refer to it as the "Trace".
I'm not sure that it is wise to judge national character on the basis of these postings on the Randon list--this was, after all, in response to a call for unusual tips. I would say that the balance between parochial and cosmopolitan types is about the same in the US as it is in the UK--at least among randoneurs. And, while I am a northerner, and would be quite happy for the South to secede and keep their destructive politics to themselves, there are wonderful and interesting places to ride all over the south. I'm a bit startled by the impulse to write off whole peoples and whole swaths of the earth--especially while pointing to the limited worldview of others.
I'm a bit startled by the impulse to write off whole peoples and whole swaths of the earth--especially while pointing to the limited worldview of others.
I have no doubt some folk who post on YACF would feel perfectly at home in the 'South' while others would match your 'northern' viewpoint. Part and parcel of internet forums and soooo easy to post something rather than say the same in a face-to-face manner. I always take forums with 'a pinch of salt'!
Maybe Vorsprung meant that there's so much great cycling on offer closer to home in Europe.
It's been almost sixteen years since I was in the U.S. I'd like to go back and the south in particular is of interest to me for the music that's come out of there.
It would be great to go to Nashville, Muscle Shoals, Clarksdale but I'd probably want to see it properly at leisure rather than ride through it on a cycling event.
The food, definitely the food (though I am sure the people, scenery, culture would all be great because it's different and different is interesting and makes life's experiences).
A long ride fuelled on Creole? It'd be awesome.

Gold Star family memorial honors ultimate sacrifice
Eric Petermann |Herald/Review
SIERRA VISTA — Sierra Vista has joined the ranks of locations where Gold Star families are " … surrounded by love and honor," in the words of Arizona U.S. Sen. Martha McSally.
On Saturday, local dignitaries, Medal of Honor recipient Hershel "Woody" Williams and other prominent military and civilian officials gathered at the Southern Arizona Memorial Veterans Cemetery to celebrate the unveiling of a monument honoring Gold Star families.
"This is not about me, it's about them," said Williams, 96, who earned distinction serving as a Marine in Iwo Jima during World War II. "We're gathered here today to do something that we as a country have not done and should have done a long time ago."
The black-granite, 14-foot-long monument features a life-size cutout of a saluting soldier and is flanked by massive stone panels that honor the homeland, family, patriotism and sacrifice of Gold Star families.
Heather Hocker, a Gold Star mother, directed the effort to raise $65,000 for the purchase and placement of the monument. Hocker's son, Joel, died in a 2011 automobile accident while in service to the Army. She said the memorial is a source of comfort and peace for those who are living with the loss of a family member.
"There's no greater gift you can give the parent of a fallen soldier than to let them know that you remember," Hocker told an audience numbering more than 300 during the dedication ceremony.
The Hershel "Woody" Williams Medal of Honor Foundation honors Gold Star families, relatives and children by building Gold Star Families Memorial Monuments throughout the United States. Sierra Vista is now one of 65 locations in 43 states where a monument has been constructed. Another 63 locations are " … in progress," Williams said.
"Eventually, we're going to get them all, we're going to get them in all 50 states," he said.
Sen. McSally said the monument was an example of the community coming together in support of Gold Star Mothers and veterans.
"Once again, Sierra Vista is setting an example for other communities around the state and throughout the nation," she said.

Inebni, auch Amenemnechu genannt, war ein ägyptischer Beamter. Er verwaltete als "Königssohn von Kusch" die nubischen Provinzen Ägyptens während der Regierungszeit der altägyptischen Königin Hatschepsut (etwa 1479 bis 1458 v. Chr.).

Die Identität von Inebni und Amenemnechu war lange Zeit umstritten. Es ist davon ausgegangen worden, dass es sich um zwei verschiedene Personen handelte. Eine Inschrift bei Tombos in Nubien hat aber gezeigt, dass es sich um eine Person mit zwei Namen handelte. Inebni ist von etwa acht oder neun Felsinschriften aus Nubien bekannt. Ferner gibt es von ihm eine Statue, die eventuell aus Theben stammt und eine Statue aus Buhen. Anhand der Inschriften war Inebni ab dem 18. Regierungsjahr Hatschepsuts und Thutmosis III. im Amt. Im 23. Regierungsjahr von Thutmosis III. ist dagegen schon Nehy in diesem Amt bezeugt, der sein Amtsnachfolger war.
