Q: Node Scripts: Chaining commands with watchify I'm using npm scripts (see my npm file below) to watch files for changes with watchify and then compile and notify once compiled. However what happens is that the watchify task runs (this takes 40s when first run) then the notify:js task gets immediately called. I would like the notify:js to be called after watchify has finished compiling.
{
  "dependencies": {
    "react": "^0.14.3",
    "react-dom": "^0.14.3"
  },
  "devDependencies": {

    "notify:js": "osx-notifier --title 'JavaScript Compiled' --message 'JavaScript compiled to build/bundle.js' --type pass"
  }
}

I've tried the following command variations.
watchify src/app.js -o build/bundle.js -t [ babelify --presets [ es2015 react ] ] \
-dv & npm run notify:js

The above command does the same as the | operator.
watchify src/app.js -o build/bundle.js -t [ babelify --presets [ es2015 react ] ] \
-dv && npm run notify:js

The above command does the same as the & operator.
I can't see any option in the watchify documentation for what I am trying to achieve. Am I missing something here or is this not possible with the way I am trying to do this?

A: I solved this using nodemon and browserify-incremental.
This compiles JavaScript into a bundle.js file.
browserifyinc -e resources/assets/js/app.js -o public/assets/js/bundle.js --cachefile .browserify-cache.json && npm run notify:js

This is my package.json file.

The track The Boy Who Melts The Sun by the L.A. "indie chamber pop" group Emael feels like an Alice in Wonderland kind of happening.... the song itself shape shifts organically and electronically. The tempo ramps up and then slows down leaving you breathless at times creating emotional tensions that give way to stirring choral melodies.
The comparison to Radiohead and Hiatus Kaiyote is inevitable.
Multi-instrumentalist musical visionary front man Emmanuel Ventura-Cruess formed the band from his most talented friends in 2014.
Emael has spent the last two years defying genres and working with Grammy nominated producer Itai Shapira crafting their debut album "Glasswork" which I look forward to experiencing.

Experience Movement and Sound Through Genesis Baez's Photographs
October 12, 2020|INTERVIEWS|Cristina Samper
Genesis Báez, a Brooklyn-based artist working with photography and video, produces work in Puerto Rico and its diaspora. Her work explores themes of movement, transference, imagination, and memory. The subject matter, be it a large vessel of water carried by two pairs of hands, or a bedroom lined with colored veils, places the viewer in dialogue with the scene at hand. Read on to learn more about the mind of this up and coming artist, her upbringing, and the intricacies of her roots reflected in her work.
Tell us a little bit about yourself. Where are you originally from, and when did art first enter your life?
I'm an artist living in Brooklyn, NY, and I make photographs and videos. I was born in Massachusetts, and grew up there and in Puerto Rico, where my family is from. I have spent my adult life living in various parts of the northeastern US. Moving a lot, and at times dividing my life between the Caribbean and New England, has influenced my practice. My current interests in imagination, perception, sensorial memory, and the multidimensionality of presence are all rooted in my diasporic experience. Many of my interests stem from considering how people make space, and relate to place and each other, in the aftermath of mass migration.
Art, but more broadly, creativity and ingenuity, have always been a part of my world, my survival, and how I connected to history. The stories shared by my elders, listening and dancing to music with neighbors, photographs carefully curated on the walls of relatives home's, brilliantly sewn garments. There was little distinction between art and life.
Before I was born, my late grandfather built my brother a conga drum from found materials. One day, I looked at the inside of the drum, held it up to the sun, and found that the head of the drum was made from an x-ray of my grandfather's chest that glowed in the light. I'm moved by this kind of ingenuity, and by the potential in everything around us. Like my grandfather, I work with what is around me.
My brother helped me sign up for my first photography class when I was 15. When I was 9, I started making pictures in Puerto Rico of everything around me so that I wouldn't forget that part of my life when I went back to the US. Pictures were (are) portals.
Tell us about your creative process. What does a day of shooting look like?
My process varies depending on what I'm making, but overall I work very intuitively. I make portraits, I photograph in spaces of personal significance or significance to my ideas, and I also construct scenes for the camera. I also make video works that engage with other people. My work has been made in Puerto Rico and various parts of the diaspora in the US, but it is not limited to a particular geography.
I also spend a lot of time listening, reflecting and digesting information without the camera.
When photographing people, the process begins with a sincere connection with a person. Sometimes they're a family member or friend, and sometimes they're a stranger. Recently (pre-pandemic), I've made pictures with other Puerto Rican women in PR and the US. We first meet and discuss ideas without the camera. When we meet again for photographs, they're typically staged. I'll have an idea or a gesture in mind that I'll ask the person to perform for the camera. That's just how we start. Improvising leads the rest of the way.
I also have a growing list of symbols, words, and ideas I'm looking for in the world, and sometimes find, if I'm lucky. For example, the ring of condensation on the airport window in San Juan, or the handful of photographs meticulously taped together onto a botanica window in the Bronx. I was moving through the world thinking about humidity, about hot and cold air clashing, and about fragments coming together to form a whole. Other times, I intervene and set things up in order to abstract or fragment space, such as leaning a broken mirror onto my Mom's tropical-green living room wall.
In the past, a body of work would be bound by a place, such as Otra Vida, Otra Vez (2011-2016), which was mostly made in Yabucoa, Puerto Rico. Today, the photographs are united primarily by ideas, symbols, gestures, light, colors, and materials.
I'm writing this in October of 2020. The collective uncertainty is massive. It's hard to say. But without a doubt, nurturing my intuition, taking care of myself, and trying to be as present as possible for my loved ones.
Taking care of myself also means making space for creative energy to move through me. I have been very fatigued with the ongoing, unfolding tragedy we are living. But my studio (or creative time, in the studio or out) is a sanctuary. I'm curious about how this time will change my work in the long run, and I am open to new ways of thinking and working. I'm currently making photographs and videos in my home and on my studio roof. I continue to think a lot about imagination, presence/absence, light/shadow, and the possibilities in negative space and the unknown. I'm making things with cut out images of skies, copies of photos of women in my family from an album that survived the hurricane, broken mirrors, and lots of tape. My memory card is full of blue skies at various times of the day. I'm playing, and listening.
If you could have a coffee chat with one inspirational figure, who would it be?
I've been thinking a lot about the writer and poet Ocean Vuong, and how affirming his writing is to my life and practice. I feel held by his work. An image from On Earth We're Briefly Gorgeous has stuck with me for months- "He is asking a question, or questions, he is turning the air around his words into weather. Is there a language for falling out of language?"
Have you ever experimented with other artistic mediums?
Yes! Drawing, sewing, theatre, dance, sound, music, creative writing, the list goes on. In college, I studied painting, drawing, and sculpture in addition to photography. Recently I have explored performance, which eventually made its way into my photographic practice. Currently, in addition to making photographs, I make videos. The camera has resonated with me the most.
How would you relate your work to the political turmoil taking place in the USA?
My work is being made from within these conditions, so it is inherently related to it. However, even before 2020, my work and I have grappled with various forms of precarity. For example, a space in one photo from a few years ago no longer exists, a person photographed in their home has had to leave that home, and a landscape in a body of work has completely transformed due to climate change. Grappling with the realities and consequences of systemic violence has been part of my practice, and life, for a long time.
Amongst many things, when I look at my recent and current work I see fragmentation, care between people, space-making where space did not previously exist, and the possibilities in the unknown. These ideas resonate with me today, especially.
If you could go back 10 years, what would you tell your former self?
You are enough. Don't be afraid.
Do you remember the first time you realised you wanted to become a photographer? Could you tell us about that memory?
I remember looking at something really familiar and mundane, and then seeing it transform before my eyes once I photographed it, and it felt like a super power. It really felt like magic.
I can recall the feeling of understanding, at a young age, that art-making was a spacious place, and a place that held me and my multiplicity like no other. I still feel this way.
What could you say about the role of what you call the diasporic life in your work?
It's a part of my life and experience that is very vast, inspires me, aches, and keeps me restless. It is often a starting point for my inquiries. It is the universe from which a lot of my work comes from, but is not bound to.
At the end of every interview we like to ask the artist to recommend a friend whose work you'd like us to interview next. Who would you suggest?
Jenny Calivas! I am constantly learning so much from her, and from her work and process. I feel deeply affirmed and uplifted by Jenny. She's amazing!

Haiti's President Michel Martelly honored Maria Bello on Tuesday for her advocacy work on behalf of the Caribbean country's women.
The star of "Coyote Ugly" and "A History of Violence" was named goodwill ambassador for women at a special ceremony on the grounds of the National Palace. Bello spoke about how a group of women in a displacement camp organized themselves after the 2010 earthquake.
"I'm very fortunate to be in the position where I can hear your voices and tell the world what you have to say," Bello told an audience at the Palace as Martelly stood at her side.
Bello, co-founder of women's grassroots group We Advance, will join the ranks of other Hollywood celebrities in Haiti who have received similar recognition for their charity work after the quake. They include actor Sean Penn, hip-hop star Wyclef Jean and Czech supermodel Petra Nemcova.
The ceremony also recognized the work of Danielle Saint Lot. The former government official is a longtime women's activist and was named an ambassador to find funding for women's causes.

Q: how are search strings added to resolv.conf? My system has this:
 $cat /etc/resolv.conf
 search myweb.com
 nameserver 171.70.168.183
 nameserver 2.2.2.2

But when I booted my system(actually in pristine condition) this search line with
myweb.com wasn't present.
Did the DNS server add it?
And if it did add it then why didnt all the hosts connected to the same DNS get that search param? It happened only on a few.

A: it is usually the DHCP client that updates /etc/resolv.conf because the DHCP server can push some options such as the domain or the DNSs to the clients.

A: Search domains are typically added to resolve.conf when the system is installed or when dhcpcd receives DNS information while obtaining a DHCP lease.

Supporting Local: An Interview with Flipreads
by KB Meniado
Not many years ago, the main competition in book selling was only the now defunct Multiply (at least, locally) and when readers weren't that Book Depository-savvy. Those times were relatively difficult for book-hunting because these sites weren't specially tailored for book selling.
However, recent times have seen easier ways to get those once-unreachable titles, especially those whose physical copies have already run out, leaving behind only digital copies. For the readers prowling the web for sites that offer limited editions or hard-to-find Filipino ebooks, Flipreads may just be the answer.
Charles Tan, retail head of Flipreads, takes us inside the first e-bookstore in the country.
THE NITTY-GRITTY OF THE EBOOK BUSINESS
Hi, Charles! Thank you for this opportunity to talk about Flipreads. Can you share with us what Flipreads is all about?
Launched by Flipside Publishing in November 2011, Flipreads is the first operational ebookstore in the Philippines. It is basically a retail store where readers can purchase ebooks at their convenience.
Over the years, we've added payment gateways, especially those from cash-based providers since we acknowledge that many Filipinos won't necessarily have access to credit cards. Some of our buyers now pay for their ebooks in 7-Eleven stores, for instance.
Flipreads is also device- and platform-agnostic, so the ebooks you buy can be read whether you're using Windows or OS X, an Android phone or an iOS phone.
With Instagram feeds and Book Depository, online bookselling and buying are not foreign to Filipino readers anymore. Flipreads, however, is on a different scale. How does it work?
One significant difference between the sites you mentioned is that they usually sell physical goods while Flipreads exclusively sells digital goods.
From the buyer's side, if there's any ebook they want, all they need to do is sign up, order the book and select a payment gateway. Some payment gateways, like PayPal, will immediately process the order while others will take some time to process, depending on when you pay for your order and our office hours. Once that has been completed, they can automatically download their ebook.
From the seller's side, they contact us and sign a sales agreement. Once we have their sales agreement, we're authorized to sell their ebooks on our website. We provide sellers sales reports once a month.
Currently, our promotions tend to be word-of-mouth and some social media presence, in addition to appearing and sponsoring some reader-related events like Filipino ReaderCon.
Buying books from Flipreads sounds easy! The range of Filipino titles on the site looks diverse as well, being that local literature is difficult to find. How do you acquire these books?
When we started out, most of the books on Flipreads were ebooks published by Flipside Publishing, which included co-publishing deals with publishers like The University of the Philippines Press and Precious Pages, comics like Tabi Po and Trese, or fiction titles like Alternative Alamat and Woman in a Frame.
Adding to that, we approached some publishers and authors and asked them if they wanted to distribute their books with us. And that was what happened with our comics collection, as we currently have around 120 comics by Filipino creators on the website.
Other times, some authors and publishers also approach us via the website and we're happy to host and feature their content on the website, as long as they meet all the requirements and are willing to do the paperwork. Our mentality is that we're not really a curator, but more of an avenue where readers can read and purchase local work.
Surely, Flipreads has had its ups and downs over the years. Can you share with us your best times and worst challenges as an ebookstore?
Some of the best times we've had are our interactions with fellow readers, be that face-to-face or online.
On the other hand, arguably the biggest challenge for us is spreading awareness that we exist and how to use ebooks. Or that sometimes, some customers still mistake us for selling physical books and mailing it to them.
Plans we should look forward to?
We're planning on overhauling our system so it's more user-friendly and has a better search algorithm. We're also looking into expanding our current payment gateways so that readers will have more options.
PRINT AND ELECTRONICS, NOT VERSUS
What do you think of the reading in the Philippines?
I think we have a lot of readers in the Philippines, both for print and electronic. The challenge is to get them to focus on local writing as well.
Any thoughts on print books and ebooks?
The biggest problem is people like to make this topic a controversial issue and frame the dialog as print versus ebooks. Why not both? What we're interested in are developing readers, and whether you consume them via print or electronically, then it shouldn't be an issue. We're just happy there's more to go around, which is better for readers. ☁

First in State Hearing Implant
By Kristen Parker
Writer / Kristen Parker
Photographer / Forrest Mellott
Nearly since birth, Braydon Dixon has had issues with his ears. He began having ear infections very early in life, with his eardrum rupturing at three months old. By the age of one, he was not walking and was scarcely making any sounds. At 18 months, he was receiving First Steps therapy for speech, as well as occupational therapy. By the age of two, he had his adenoids removed and tubes in his ears at least seven times. Doctors saw improvement as he learned to talk and walk, but his parents knew his hearing was affected, presumably by the ear infections.
Tumors in His Ears
Fast forward two years: when Braydon was four, doctors discovered that he had cholesteatomas, which are noncancerous tumors that can destroy the bones of hearing as they grow. When the skin of a ruptured eardrum grows through the hole into the middle ear, a cholesteatoma forms. If there is an infection in the middle ear, the skin continues to grow until becoming a tumor called a cholesteatoma. These tumors are extremely rare, but Braydon's case was significant in that he had them in both ears. In addition, both had spidered in their growth to encompass his ossicles (the bones located in the middle ear). When they surgically removed the cholesteatomas, the ossicles came with them.
This left Braydon with significant hearing loss. However, no one knew just how considerable the loss was until he was in second grade, when during a hearing test the therapist discovered that he was reading her lips. "He did fine repeating her, until she covered her mouth," said his mom Reagan. "Then we knew how bad his hearing was."
Hearing aids were next for Braydon, though they were not as helpful as the family had hoped they would be. Traditional hearing aids are designed to help the bones vibrate, but since Braydon lacks some of the bones in his ear, he still could not hear well. Discouraged, the family felt as though they were back to square one.
A New Technology Solution
Then they learned about a new bone conduction implant developed by Cochlear Limited: the Baha Attract System. This technology uses a magnet implanted under the skin to hold the device in place. Previous technology in this area inserted a small titanium implant into the bone behind the patient's ear. This implant, called an abutment, would also protrude through the skin and the sound processor (the Baha) attached to it.
After studying, researching, and asking many questions, Braydon felt confident that this was the right choice for him. His parents let him make the decision for himself because "ultimately he is the one who has to live with it…not us. We are teaching him to advocate for himself," said Reagan.
The Baha Attract just received FDA approval in November, and in February, Braydon was the first person in Indiana to receive one. The surgery, performed locally at Riley Hospital in Indianapolis, was only on his left ear; surgery for his right ear just took place in June.
The family felt the Baha Attract was the best option for Braydon. Since the surgery to implant the Baha Attract, "[Braydon] is much more willing to wear this device than the ones we have tried previously. Regardless of the current state of his ears' disease, this device allows his hearing to be unaffected," said his dad, Dave Dixon.
For his mom, the best part is that "the Baha has Bluetooth technology so he can listen to his music or a game without the rest of us having to hear it. Also, we can now watch TV or go to the movies and he can actually hear what is being said…he can hear whispers now that he couldn't before," she said.
"And he appears to feel more comfortable in general, now that he has hearing. Without the Attract, it is scary for him," said his sister Kaylin. "Braydon is an amazing kid who has gone through a lot. He is a real trooper and I am very proud of him. I know not everyone agrees with implantation but this was my brother's choice and this is his life. I think it is awesome that he was able to make this choice for his body and his life. This is his journey; we are just here to support him."
According to Braydon, "The best part is that now I can hear and I can't feel it. And I can hear my friends."
"Throughout the community we have had awesome support. All the kids know him and don't give him a hard time about it. We've had the opportunity to teach others about this groundbreaking technology," said Reagan. "It makes me scared to think of ever leaving this community."

Everyone in cricket is reminded that the Relevant Codes of Conduct apply online and in text and email communications, just as they do in the 'real world.' Many cricket clubs have formally adopted this expectation into their constitution and / or disciplinary processes.
Social Media, when used properly, is exciting and opens up a lot of opportunities, but at times it can seem strange and even intimidating for people who did not 'grow up' with it. Facebook, Twitter, texting, Blackberry messenger, online gaming and personal emails are everywhere. By following some simple guidelines potential pitfalls can be avoided, and Social Media can be safely used as a promotional tool and a means of communication for the club.
The Children Act defines a person under 18 years as a child . You should make arrangements for under 18s via their parents or carers; this includes text and email messages. It is understood that in the case of over 16's this may not be ideal for yourself or the parents. An acceptable exception to this rule is to text or email the parent and to copy in the 16 or 17 year old, with the parent's prior consent. This means the parent is able to monitor communications, but the 16 or 17 year old receives the information directly. If you receive any responses from that appear inappropriate they should be brought to the attention of the parent or carer. You should not engage in individual text or email conversations with a 16 or 17 year old without their parent receiving the same messages from you. All contact with children should be in relation to coaching, matches and cricket-related activity.
Please be mindful of who may have access to material you share via social media, including Facebook, twitter and other platforms.
We're all in this together to create a welcoming environment, Let's treat everyone with respect. Healthy debates are natural, but kindness is required.


The calendar listed below is current as of the date above. Training dates and locations are subject to change, sometimes without notice. For additional information, regarding these courses, please direct your questions to COMU@hq.dhs.gov, or visit DHS ICTAP SCIP Resources for any updates to this information.

Borophene: A prospective extraordinary sodium anode material
(Nanowerk News) Sodium-based batteries have drawn considerable attention as a prospective alternative to lithium-based batteries due to the abundance and low price of sodium element. However, finding a suitable anode material has been a long-standing critical task before the commercialization of sodium-based batteries.
As the size of sodium atom is much larger than that of lithium atom, many anode materials widely used in lithium-based batteries show poor performance in sodium-based batteries, most of which suffering from low intercalation utility, slow kinetics and sever volume expansion.
Recently, a research team led by Prof. Tianshou Zhao at the Hong Kong University of Science and Technology comprehensively investigated the feasibility of employing borophene, a newly synthesized 2D sheet of boron, as an anode material for sodium-based batteries via ab initio calculations ("Ab initio prediction of borophene as an extraordinary anode material exhibiting ultrafast directional sodium diffusion for sodium-based batteries").
This is a schematic drawing of sodium diffusion on borophene and the comparison about capacity and relative sodium diffusivity with other reported sodium anode materials. (© Science China Press) (click on image to enlarge)
The calculation results show that during charge, the maximum Na/B ratio can reach 0.5 (Na0.5B), corresponding to a capacity of as high as 1218 mAh·g-1 . The unique buckling structure of borophene leads to an anisotropic diffusion behavior.
Along the valley direction of borophene, the diffusion energy barrier for sodium is as low as 0.0019 eV, corresponding to an ultrahigh sodium diffusivity, which is estimated to be more than a thousand times higher than that of conventional anode materials and one to seven magnitudes higher than other previously reported 2D materials.
This ultrahigh diffusivity is expected to revolutionize the rate capability of sodium-based batteries. During the charge and discharge process, the metallic feature and structural integrity of borophene is predicted to be well preserved, which ensures good electronic conductivity and stable cyclability. The calculated average open circuit voltages (OCV) is 0.53 V, which is an appropriate value for sodium-based batteries to maintain a high energy density while effectively suppressing the dendrite formation.
Till now, compared with other reported sodium anode materials, borophene holds the highest sodium diffusivity.

Voters Turning Democrat Blue Wave Hopes into Disaster
The Democrats not only expect to take back control of the House of Representatives in the November midterm elections, they're already planning what to do when they do: impeach the president, continue to investigate Kavanaugh, repeal Trump's tax reforms, and raise taxes. They think they will turn between 30 and 50 seats from red to blue.
After all, they have history and The Cook Political Report on their side. History says that the party occupying the White House will lose seats in the midterms, especially if it's the president's first term, and especially if his approval rating is in the 40s or lower. According to Cook, 38 Republican-held seats are rated as "toss-up" or worse, with another 27 seats in the "lean Republican" category, meaning Republicans have a tentative advantage but the races are competitive. According to Dan Balz, writing in the Washington Post, "The party that holds the White House almost always loses seats in midterm elections, especially during a president's first term, and especially when a president's rating is below 50 percent."
Almost always.
The kind of behavior we're seeing today on the political left has been bought and paid for. To see how, click here and request a high-quality, FREE report that identifies the number-one political revolutionary in America today.
The Democrats' biggest enemy is themselves. First, their obscene performance during the Kavanaugh hearings has energized the sleeping Republicans who in several polls taken during and after the hearings have awakened from their slumber and have closed the gap in generic voting almost to zero. CNN's poll released on Monday showed severe damage being inflicted on the most critical part of the electorate the Democrats need to capture in the upcoming midterm elections: Independent voters. When asked "Do you approve or disapprove of the way the Democrats in the U.S. Senate handled Kavanaugh's confirmation hearing?" 58 percent of independent voters disapproved compared to just 30 percent who approved – a jaw-dropping 28 percent margin.
An NPR/PBS NewsHour/Marist poll taken during the hearings showed any "wide Democratic enthusiasm advantage that has defined the 2018 campaign up to this point has disappeared." In a previous poll in July, there was a 10-point gap between the number of Democrats and Republicans saying that the November midterm elections were "very important." That gap is down to two points, a statistical tie, according to the poll. Lee Miringoff, director of the Marist Institute which conducted the poll, said "The results of [the Kavanaugh] hearings, at least in the short run, is the Republican base was awakened."
According to a poll taken by Quinnipiac University just before the hearings began, the Democrat advantage in a generic vote had been cut in half compared to a similar poll taken just two weeks earlier. The September 12 survey showed Democrats with a 52-38 percent lead over Republicans, a 14-point gap. Two weeks later, in the survey taken between September 27 and 30, that advantage had shrunk to seven points, 49-42.
In its weekly poll released on Wednesday, Rasmussen Reports found that the Democrat advantage over Republicans in a generic poll had vanished altogether: 45-45. The previous week Democrats held a 5-point lead over Republicans, 47-42.
Helping along is the disgusting performance of Democrats during the funeral service for Senator John McCain. The funeral service of McCain was, according to the liberal New Yorker magazine, "the biggest resistance meeting yet":
Donald Trump's name was never mentioned. It didn't have to be. The funeral service for John Sidney McCain III, at the Washington National Cathedral, on this swampy Saturday morning, was all about a rebuke to the pointedly uninvited current President of the United States, which was exactly how McCain had planned it.
Turning a somber time of reflection and prayer into a political resistance meeting reminded Monica Showalter of The American Thinker of another time when a funeral was turned into a political rally, and it cost the Democrats in the midterms. Wrote Showalter:
[Paul] Wellstone was a well-liked Democratic senator from Minnesota who died in a plane crash in 2002. In the midst of public turmoil back in Washington, what with Bush Derangement Syndrome going full blast and midterms eleven days away, his funeral ended up amounting to a political rah-rah session, a "pep rally" and a "partisan foot-stomp" for the Democratic Party instead of a memorial to a man who was supposedly loved by Democrats.
What it showed was that midterms were more important to Democrats than honoring a man who had died. For the rest of us, it was just disgusting.
Eleven days later, the Democrats, instead of gaining in Congress, lost two Senate seats and eight House seats.
With all the momentum on the side of the Republicans (thanks to the Democrats' outrageous and offensive behaviors), the supposed Blue Wave could turn into Alabama's Crimson Tide. For the record, ESPN predicts that the Tide, having already won six games, has an 80 percent chance of winning each of the remaining ones on its schedule.
This forecaster thinks the Democrats will suffer a defeat worse than the one they brought on themselves in November 2002.

Newspaper and magazine publishers have adopted many tactics for surviving the big bad wolf of disruption threatening to blow down their carefully constructed houses, but over 2014 the media industry seemed to identify two key areas as built more of bricks than straw.
Presentations from the Guardian and News UK at the Media Research Group conference in Berlin highlighted just how complex measuring what a newspaper does in the digital age has become.
New stats from YouGov show six percent of the UK already own wearable tech, and 13 percent will do so by this time next year. As wearables get into the hands (and on to the bodies) of more people, it's time for the news industry to start thinking seriously about how they're going to take advantage.
This is the second in a series of posts from media consultant Neil Sharman, looking at how publishers are integrating data use into their businesses. Here, Sharman looks at some of the challenges they face doing so.


Snowfall was expected on Dec. 19. The Village of Farmingdale had more than enough warning to be ready to clear the roads, but where were Mayor Starkie and his administration?
Many roads were inadequately plowed and it took two days of cold and ice to have sand put down on some roads. This all begs the question of whether Mayor Starkie's pick for superintendent of the Department of Public Works is truly qualified for his position. I personally have requested from this administration the qualifications that were used to pick a new head of DPW who gets paid $85,000 annually with very generous benefits, but I was told there are none. Can you imagine another village hiring a DPW superintendent where there are no qualifications?
Our DPW head is no doubt a fine person, but he is also a lifelong friend of Mayor Starkie, which again begs the question of what are his qualifications to head such an important department in our village. If you remember during Mr. Starkie's mayoral campaign, he did say that he would get the best-qualified individuals and not resort to any patronization. I will let the residents decide if such a statement is true.
I have also publicly asked Mayor Starkie and the board if they would consider voting to eliminate the board's lifetime medical benefits and the benefits of other part time officials. With our property taxes rising, our school taxes rising, this would be a great way to save our residents money and the reason why I made this proposal to the board. The Nassau County comptroller calculates the cost to taxpayers is over a half million dollars per person. Our small village can no longer afford to pay for such perks. Why does the mayor refuse to entertain discussions on the subject?
I urge residents to come to the village board meetings and start questioning the practices of this administration. The board meets Monday evenings and is open to the public. Check the village website for times or call the village.

The 1913 premiere of Stravinsky's ballet The Rite of Spring created an uproar whose repercussions changed the course of dance and music in the 20th century. A hundred years later, two titans of the American performing arts have joined forces to create a thrilling new dance-theater performance that celebrates that legendary opening night.
A Rite is a collaboration between choreographer Bill T. Jones (a resident artist at Bard) and director Anne Bogart (a Bard alumna). Their respective companies of dancers and actors have come together to develop a contemporary response to Stravinsky's masterpiece.
A Rite will be performed as part of Bard SummerScape on 7/6 and 7/7.

Women climbers in Nepal on world record chase
17 March 2010, 15:56
By Claire Cozens (AFP)
KATHMANDU — Two elite mountaineers will next month attempt to climb one of the deadliest Himalayan peaks, Annapurna, as they vie to become the first woman to scale the world's 14 highest mountains.
South Korea's Oh Eun-Sun and Edurne Pasaban from Spain are among a handful of female climbers competing to be the first female to reach the summit of every mountain over 8,000 metres (26,247 feet).
Italy's Reinhold Messner became the first person to climb all 14 peaks in 1986, but the record has never been equalled by a woman, and Oh and Pasaban are both hoping to make the history books this year.
Oh is the closest to achieving the record with 13 of the 14 peaks -- all of which are in the Himalaya and Karakorum mountain ranges -- already under her belt.
"If I manage to do this I will be incredibly proud, not just for myself but for my country and for Asia," the 43-year-old South Korean told AFP after arriving in the Nepalese capital Kathmandu for the expedition.
"I don't know why no female climber has managed it. I suppose it is down to women's position in the world, which is still not the same as men's."
Oh's chief rival, Pasaban, has two mountains left to climb -- Annapurna and Shisha Pangma in China's Tibet region -- and hopes to attempt both in the brief April-May pre-monsoon season, when weather conditions are favourable.
She had hoped to travel to Tibet first, allowing her to acclimatise before attempting the more difficult Annapurna later in the season.
The 8,091-metre mountain is particularly dangerous because it is both technically difficult and avalanche-prone, and it has a much higher death rate than Everest.
But the Chinese authorities refused her permission to travel there this month, leaving her with no choice but to attempt Annapurna next.
Other competitors for the record are Austria's Gerlinde Kaltenbrunner and Nives Meroi of Italy.
Kaltenbrunner failed in August in a bid to climb the 8,611-metre K2, the world's second highest peak, situated on the Pakistan-China border and regarded as the most difficult of all the eight-thousanders.
She remains at 12 summits, and must still scale Everest on the Nepal-China border, which at 8,848 metres is the world's highest peak. Meroi has conquered 11.
Like Oh, Pasaban has been defeated by Annapurna once before, in 2007 when she and her team turned back about 1,000 metres from the summit in bad weather.
"Annapurna is difficult and dangerous. Some people say it's the most dangerous of them all, and many of my friends have died there. So I go with a little fear," she said in an interview with AFP in Kathmandu.
"If I wasn't trying to do this, I probably wouldn't attempt it. But all my life has been about the eight-thousanders."
Both women will attempt the climb in early April, after spending a month at altitude to acclimatise and train for the task ahead.
Pasaban, 36, who never uses oxygen on her expeditions, admits she has given up much for her sport -- more, perhaps, than her male counterparts.
"The years between 30 and 40 are the best ones for a female climber, but they are also the years that our culture dictates that we should spend having a family," she said.
"A few years ago I faced a lot of family pressure to settle down, and I became quite depressed. But now I am very clear about my goals."
Pasaban admits it will now be hard to beat Oh to the record, although she hints that her South Korean rival's sponsorship deals may have given her an advantage.
Unlike Pasaban, Oh will travel by helicopter to base camp, and have all her ropes set up for her before she arrives.
"Many people speak about competition in the mountains. I think it would have been nice for us to arrive at the top together," said Pasaban.
"But we have decided to climb separately. The mountain will put us in our places."

It seems like just yesterday that I was lamenting about the frigid May temperatures we were experiencing here in Minnesota. Actually, it was only two short weeks ago when we woke up to snow one morning and frost the next. Scenes like this in May are disheartening for anyone, but especially for a gardener.
My perennial gardens endured these frigid temperatures, however, and bounced back quickly.
This past week we have seen much warmer temperatures and starting yesterday, the humidity rolled in too. Today, just two weeks after temperatures in the high 20's, it is in the mid-90's with a dew point of 64. The air is thick and oppressive. The National Weather Service has even issued an "excessive heat" warning. Bottom line is that it is damn hot and miserable.
Instead of snow and freezing temperatures, my perennial gardens must now suffer under this punishing Minnesota heat. The same Autumn Joy Seedum plants pictures above with snow look like this today.
Every Saturday I make a trip into the big city to take our daughter to rehearsal for the youth symphony. This weekend she also has a piano theory exam to take at a local college. I'm waiting for her now. I spend a lot of time driving and waiting for my kids at various activities these days. It's one of the reasons I decided to start blogging. Recording aspects of our country life provides me with an outlet while I wait at practices, rehearsals and lessons in my crazy and chaotic modern life.
Today is a dreary and rainy winter day in Minnesota and it definitely doesn't feel like January. Instead, it feels more like April with its snow-melting spring rains and I'm daydreaming about spring and my gardens. I've started noticing the gardening magazines in the grocery store check-out line. Although they call out to me as I stand in line, I have resisted purchasing any so far. The seed catalogs have also started to arrive in the mail and I peruse them with grand ideas of all the different vegetable varieties I am going to try this year.
My real gardening passion is flowers. As each growing season comes to an end, I contemplate all the things that I will grow "next year" in my flower gardens. On this rainy day, looking at random pictures of my flowers cheers me up and inspires me for the upcoming growing season….even if it is months away.

Point University Athletic Director Alan Wilson retires after 25 years
Published 9:19 am Thursday, July 15, 2021
On Monday, Point University Athletic Director Alan Wilson announced his retirement, effective September 2021. Wilson has been a part of the athletic department at Point since 1996 and has spent the last 10 years serving as the Skyhawks' athletic director.
"It is a bittersweet moment for me to announce my retirement after over 35 years in the field of athletics. I have been extremely fortunate to have the privilege of serving as a coach and the athletic director of Point University for most of that time. I am grateful to have been allowed to work in the field that I love while serving our Lord and Savior Jesus Christ," Wilson said in a press release. "I have worked with so many wonderful coaches, support staff, and athletes that my time at Point has been the best of my career. They are the heart and soul of the university, and I was privileged to serve alongside them and enjoy the many successes that have come their way."
Wilson started at Point, when it was still called Atlanta Christian College in 1996 and served as the women's basketball coach and volleyball coach. After two years of coaching volleyball, he transitioned to coaching baseball in 1998.
As the women's basketball coach, Wilson's teams produced four NCCAA All-America award winners and an NCCAA South Region champion in 2006. Point also appeared in two NCCAA National Tournaments and Wilson was named NCCAA South Region Coach of the Year three times and NCCAA National Coach of the Year in 2006. He also served as the NCCAA South Region Women's Basketball Chair from 1999-06.
Wilson served as the Skyhawks' baseball coach until 2006. He guided his teams to the NCCAA National Tournament eight times and the Skyhawks finished as national runner-up three times. He was named NCCAA South Region Coach of the Year four times and clinched South Region championships three times (2000, 2002 and 2006). Wilson also coached numerous NCCAA baseball All-Americans.
Following his tenure as the women's basketball and baseball coach, Wilson coached the men's basketball team for six seasons. He directed two NCCAA South Regional champions (2008 and 2011) and took his teams to the NCCAA National Tournament in 2009 and 2012. Wilson produced three NCCAA All-Americans and was named NCCAA South Region Coach of the Year four times. During his time as the men's basketball coach, Wilson's team entered the national rankings for the first time in program history in 2012. This was also the first time in Point history that any sport had entered the NAIA National rankings.
In the transition from Atlanta Christian to Point, Wilson was named the first athletic director under the institution's new identity in 2010. According to the press release, Wilson played an instrumental role in changing the mascot name from the Chargers to the Skyhawks, creating a new logo and establishing the current color scheme.
Under Wilson's leadership, Point's athletic programs have won numerous NCCAA regional titles and a national championship since 2010. His vision for the athletic department helped Point join the NAIA and the Appalachian Athletic Conference during the 2011-12 season, which has allowed the athletic programs at Point to continue to accumulate success.
"I'm grateful for Alan Wilson's many years of faithful service to Point and for the impact he's had on growing and maturing our athletic program," Point University President Dean Collins said. "But I'm even more thankful that Alan has impacted so many students' lives for Christ, preparing them to be servant-leaders on and off the field. He truly exemplifies Point's goal of educating the whole person."
In the past year alone under Wilson's leadership, he had two coaches named Conference Coach of the Year, eight athletes at Point earn All-American recognition and 36 athletes earn AAC All-Conference awards.
Wilson graduated from Shorter University with a bachelor of arts degree in communications in 1976. His coaching career began when he accepted a position as head basketball coach at Colonial Hills High School, which won a Georgia state high school championship in 1996. During his 10-year tenure at Colonial Hills, Wilson also coached the baseball team and served as the school's athletic director.
"I am also looking forward to the next season of life as I can enjoy some time with my wife and family," Wilson said. "They have supported me throughout my career and were completely dedicated to helping me be the absolute best I could be. It is time now to give back a small portion of what has been given to me. Thank you to all of you that have shared a part in this wonderful journey. I will forever be a Skyhawk."

NaturalNews) If you have children, you are more than likely already aware of the official U.S. Centers for Disease Control and Prevention (CDC) "Immunization Schedules," which today recommend an astounding 29 vaccines be given between birth and six years of age, including yearly flu shots, as well as another five to 16 vaccines between ages seven and 18 (http://www.cdc.gov/vaccines/schedules/). But a recent investigative report compiled by Dr. Lucija Tomljenovic, Ph.D., uncovers more than 30 years of hidden government documents exposing these vaccine schedules as a complete hoax, not to mention the fraud of the vaccines themselves to provide any real protection against disease.
Though her paper focuses primarily on the British health system's elaborate cover-up of the dirty truth about its own national vaccination program, the tenets of the study's findings still apply to vaccination schedules in general, which are typically designed for the purpose of serving corporate interests rather than public health. Government authorities, it turns out, in an ongoing bid to satisfy the private goals of the vaccine industry, have deliberately covered up pertinent information about the dangers and ineffectiveness of vaccines from parents in order to maintain a high rate of vaccination compliance. And in the process, they have put countless millions of children at risk of serious side effects and death.
"[T]he JCVI (Joint Committee on Vaccination and Immunization) made continuous efforts to withhold critical data on severe adverse reactions and contraindications to vaccinations to both parents and health practitioners in order to reach overall vaccination rates which they deemed were necessary for 'herd immunity,' a concept which ... does not rest on solid scientific evidence," explains Dr. Tomljenovic in the introduction to her paper.
These are some strong accusations, but the information Dr. Tomljenovic gathered speaks for itself. Not only did the JCVI routinely ignore questions of safety as they came up with regards to the ever-expanding vaccination schedule, but the group actively censored unfavorable data that shed a "negative" light on vaccines in order to maintain the illusion that vaccines are safe and effective. Beyond this, the JCVI regularly lied to both the public and government authorities about vaccine safety in order to ensure that people continued to vaccinate their kids.
"The extent of the JCVI's concerns with the implications of scientific assessment of vaccine safety on vaccine policy explains why they were opposed to any long-term surveillance for severe neurological disorders following vaccination," writes Dr. Tomljenovic. "[I]nstead of re-evaluating the vaccination policy, at least until safety concerns were fully evaluated, the JCVI chose to support the existing policy based on incomplete evidence that was available at that time."
In other words, the JCVI was more concerned with protecting the reputation of the dangerous MMR vaccine, as well as many other questionable vaccines, than with protecting children from sustaining serious injuries as a result of getting the jabs. As far as the MMR vaccine is concerned, this critical piece of information not only reinforces the legitimacy of Dr. Wakefield's findings from 10 years later, which were illegitimately declared to be fraudulent by the establishment, but also illustrates just how painfully long this scam has been taking place.
If this is not bad enough, Dr. Tomljenovic also drudged up copious amounts of information on the JCVI's longtime habit of encouraging vaccine companies to deliberately alter their data sheets in order to make dangerous and ineffective vaccines appear safe and effective, in accordance with their recommendations. When the JCVI's guidance contraindications for MMR, for instance, did not match those of the vaccine's manufacturer, JCVI apparently instructed the manufacturer to alter its data sheets to avoid "legal problems."
Similarly, the JCVI's official policy was to cherry-pick unreliable studies to support its own opinions on vaccines rather than rely on independent, scientifically-sound studies to make vaccine policy recommendations. Once again, the JCVI's position on the safety and effectiveness of MMR is an excellent example of this, as the group flat out ignored legitimate MMR studies in favor of industry-backed junk studies like the infamous 2005 Cochrane Review, which technically proves nothing about the alleged safety of MMR because the 31 studies it evaluated did not even meet the group's basic methodological criteria.
"Over the years, the JCVI has consistently promoted the MMR vaccine as safe, based on studies that have been proven to be either irrelevant, inconclusive, or methodologically questionable," explains Dr. Tomljenovic, adding that the JCVI routinely chose to rely on flawed epidemiological studies that only identified "association" rather than "causation," a rather ironic inaccuracy in light of how scrutinizing the establishment typically is of studies that contradict its own positions.

Den enkeltes arbejdsevne afhænger af personens legemlige, psykiske og sociale sundhedstilstand. Et menneskes samlede arbejdsydelse og endda personen selv betegnes som arbejdskraft eller arbejder. Ganske vist bruger både de autotrofe planter og de heterotrofe dyr energi under fødeoptagelse og formering, men i modsætning til dette naturlige energiforbrug er arbejdskraftforbrug kendetegnet ved, at det altid har en samfundsbestemt karakter.

I økonomisk teori er arbejdskraft en vigtig produktionsfaktor - i mange fremstillinger den eneste produktionsfaktor ud over kapital. I kapitalistiske samfund bliver arbejdskraften til en vare, der handles på arbejdsmarkedet. Arbejdskraftens pris udtrykkes i form af løn. Den kan formelt set være beregnet i forhold til en fastsat mængde producerede varer eller tjenesteydelser (akkordløn), eller den kan være opgjort i forhold til et bestemt tidsforbrug (timeløn). I begge tilfælde er der reelt tale om en beregning af energiforbrug over tid, og derfor er det også altid muligt at omregne fra akkordløn til timeløn.

Arbejdskraftens historie
Det store spring i arbejdskraftens historie blev taget, da menneskene gik fra fødesøgende til fødeproducerende levevis. dvs. da landbruget opstod. I forbindelse med den stigende arbejdsdeling opstod der efterhånden behov for uddannet arbejdskraft, mens behovet for simpelt arbejde er blevet mindre og mindre.

Det næste spring i arbejdskraftens historie blev sat i gang med mekanisering og brugen af fremmede energikilder (vand- og vindkraft, fossile brændstoffer osv.) Med industrialiseringen mangedobledes produktiviteten af arbejdskraften, dvs. at der kunne fremstilles langt flere varer ved brug af én arbejdstime.

Senest har elektronik yderligere øget produktiviteten, mens globaliseringen af markedet for varer og arbejdskraft har muliggjort en øget arbejdsdeling. Det betyder, at behovet for højt uddannet og omstillingsberedt arbejdskraft er næsten umætteligt, mens den ufaglærte arbejdskraft bliver overflødig, hvad der ytrer sig som mangel på arbejdskraft (flaskehalsproblemer), men samtidig stigende arbejdsløshed blandt ufaglærte.

Some German municipalities could imagine carrying out digital traffic controls on roads with diesel bans. Intelligent cameras are used to scan the license plates and compare them with a database. This system has many advantages, such as the ability to collect statistics at the same time and the gradual introduction of driving bans would be simplified. However, it is also associated with high costs and the question of data protection.

After claiming the title of vice champion in the 2017 Cooper Tires USF2000 Championship, KNAF Talent First car racing talent Rinus VeeKay stepped up to the next level this season, the Pro Mazda category. For this campaign VeeKay joined Juncos Racing early 2018 and it was the start of a very successful partnership. In his maiden season in the Pro Mazda Championship Presented by Cooper Tires, the then still 17-year-old racing talent from Hoofddorp in the Netherlands won seven out of sixteen races and claimed the title in commanding style, being the first champion in the history of the new and much faster PM-18 generation Pro Mazda cars.
This opened the door for VeeKay to go for his next goal and also the highest level of the Road to Indy Presented by Cooper Tires, the Indy Lights Presented by Cooper Tires. In the last few weeks VeeKay tested with the Indy Lights car and after looking into all options, the young Dutchman made his choice for the 2019 season.

Section: Taree to Coopernook
Looking north on Jones Island, north of Croki.
This section of Pacific Highway stretches from the northern end of the Taree Bypass at Cundletown to the southern end of the future Coopernook Bypass near Lansdowne River. A large portion of this section of the highway is located upon Jones Island , which is surrounded by Ghinni Ghinni Creek, Lansdowne River and the Manning River. Originally, a large number of right-angle bends had confronted motorists along this section as the highway followed the boundaries of agricultural properties on the floodplain. These corners have since been smoothed and thus there are small sections of abandoned highway pavement scattered across the island.
The first major work on this section of the highway came in 1957 when the Department of Main Roads noted in its Annual Report that "reconstruction of one major and several minor deviations on a length of 3 miles between Gill's Lane, 10 miles north of Taree, and the Lansdowne River at Coopernook, was in hand." This work involved the 1km deviation at the locality of Croki and was completed in 1958.
Five years later, in 1963, a new bridge over Ghinni Ghinni Creek was constructed on a new alignment to the north of the existing highway. This work also involved the smoothing out of a right-angle bend just west of the bridge as part of a 700m realignment.
As part of the broader Pacific Highway Upgrading Programme that was commenced in September 1996, this section of the highway was upgraded to dual carriageway standards. Work commenced in November 2001 on the earthworks and drainage, which are the most important part of the project - the land over which the highway passes is extremely swampy and must be stabilized before construction of the road base could begin. It was decided that the existing alignment of the highway would be maintained as far as possible, with the elimination of dips and curves, to ensure minimal disturbance to local dairying properties. Included as part of the project were two stock underpasses, two new bridges over Ghinni Ghinni Creek, and a number of culvert openings, which will ensure "at least one lane remains open in each direction during a 1 in 20 flood event."1 After an extensive stablisation period, the Taree to Coopernook upgrade was opened to traffic on 4 August 2005 . The steel truss bridge over Ghinni Ghinni Creek was demolished following completion of the new road.

Scientists control light scattering in graphene
(Nanowerk News) Scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley have learned to control the quantum pathways determining how light scatters in graphene. Controlled scattering provides a new tool for the study of this unique material – graphene is a single sheet of carbon just one atom thick – and may point to practical applications for controlling light and electronic states in graphene nanodevices.
The research team, led by Feng Wang of Berkeley Lab's Materials Sciences Division, made the first direct observation, in graphene, of so-called quantum interference in Raman scattering. Raman scattering is a form of "inelastic" light scattering. Unlike elastic scattering, in which the scattered light has the same color (the same energy) as the incident light, inelastically scattered light either loses energy or gains it.
Raman scattering occurs in graphene and other crystals when an incoming photon, a particle of light, excites an electron, which in turn generates a phonon together with a lower-energy photon. Phonons are vibrations of the crystal lattice, which are also treated as particles by quantum mechanics.
Quantum particles are as much waves as particles, so they can interfere with one another and even with themselves. The researchers showed that light emission can be controlled by controlling these interference pathways. They present their results in a forthcoming issue of the journal Nature, now available in Advance Online Publication ("Controlling inelastic light scattering quantum pathways in graphene").
Manipulating quantum interference, in life and in the lab
"A familiar example of quantum interference in everyday life is antireflective coating on eyeglasses," says Wang, who is also an assistant professor of physics at UC Berkeley. "A photon can follow two pathways, scattering from the coating or from the glass. Because of its quantum nature it actually follows both, and the coating is designed so that the two pathways interfere with each other and cancel light that would otherwise cause reflection."
The quantum pathways in Raman scattering are optically stimulated electronic excitations only possible if the initial electronic state is filled and the final state is empty (top). As pathways are removed by doping the graphene and lowering the Fermi energy (bottom), light from scattering may increase or decrease, depending on whether the removed pathways interfere constructively or destructively with the remaining pathways. Wang adds, "The hallmark of quantum mechanics is that if different paths are nondistinguishable, they must always interfere with each other. We can manipulate the interference among the quantum pathways that are responsible for Raman scattering in graphene because of graphene's peculiar electronic structure."
In Raman scattering, the quantum pathways are electronic excitations, which are optically stimulated by the incoming photons. These excitations can only happen when the initial electronic state is filled (by a charged particle such as an electron), and the final electronic state is empty.
Quantum mechanics describes electrons filling a material's available electronic states much as water fills the space in a glass: the "water surface" is called the Fermi level. All the electronic states below it are filled and all the states above it are empty. The filled states can be reduced by "doping" the material in order to shift the Fermi energy lower. As the Fermi energy is lowered, the electronic states just above it are removed, and the excitation pathways originating from these states are also removed.
"We were able to control the excitation pathways in graphene by electrostatically doping it – applying voltage to drive down the Fermi energy and eliminate selected states," Wang says. "An amazing thing about graphene is that its Fermi energy can be shifted by orders of magnitude larger than conventional materials. This is ultimately due to graphene's two-dimensionality and its unusual electronic bands."
The Fermi energy of undoped graphene is located at a single point, where its electronically filled bands, graphically represented as an upward-pointing cone, meet its electronically empty bands, represented as a downward-pointing cone. To move the Fermi energy appreciably requires a strong electric field.
Team member Rachel Segalman, an associate professor of chemical engineering at UC Berkeley and a faculty scientist in Berkeley Lab's Materials Sciences Division, provided the ion gel that was key to the experimental device. An ion gel confines a strongly conducting liquid in a polymer matrix. The gel was laid over a flake of graphene, grown on copper and transferred onto an insulating substrate. The charge in the graphene was adjusted by the gate voltage on the ion gel.
"So by cranking up the voltage we lowered the graphene's Fermi energy, sequentially getting rid of the higher energy electrons," says Wang. Eliminating electrons, from the highest energies on down, effectively eliminated the pathways that, when impinged upon by incoming photons, could absorb them and then emit Raman-scattered photons.
What comes of interference, constructive and destructive
"People have always known that quantum interference is important in Raman scattering, but it's been hard to see," says Wang. "Here it's really easy to see the contribution of each state."
A flake of graphene was grown on copper and transferred onto an insulating substrate of silicon dioxide. The Fermi energy in the graphene was adjusted by varying the gate voltage on the overlying ion gel, which confines a strongly conducting liquid in a polymer matrix.
Removing quantum pathways one by one alters the ways they can interfere. The changes are visible in the Raman-scattering intensity emitted by the experimental device when it was illuminated by a beam of near-infrared laser light. Although the glow from scattering is much fainter than the near-infrared excitation, changes in its brightness can be measured precisely.
"In classical physics, you'd expect to see the scattered light get dimmer as you remove excitation pathways," says Wang, but the results of the experimenter came as a surprise to everyone. "Instead the signal got stronger!"
The scattered light grew brighter as the excitation pathways were reduced – what Wang calls "a canonical signature of destructive quantum interference."
Why "destructively?" Because phonons and scattered photons can be excited by many different, nondistinguishable pathways that interfere with one another, blocking one path can either decrease or increase the light from scattering, depending on whether that pathway was interfering constructively or destructively with the others. In graphene, the lower and higher-energy pathways interfered destructively. Removing one of them thus increased the brightness of the emission.
"What we've demonstrated is the quantum-interference nature of Raman scattering," Wang says. "It was always there, but it was so hard to see that it was often overlooked."
In a second observation, the researchers found yet another unexpected example of inelastic light scattering. This one, "hot electron luminescence," didn't result from blocked quantum pathways, however.
When a strong voltage is applied and the graphene's Fermi energy is lowered, higher-energy electron states are emptied from the filled band. Electrons that are highly excited by incoming photons, enough to jump to the unfilled band, thus find additional chances to fall back to the now-vacant states in what was the filled band. But these "hot" electrons can only fall back if they emit a photon of the right frequency. The hot electron luminescence observed by the researchers has an integrated intensity a hundred times stronger than the Raman scattering.
The road taken
The poet Robert Frost wrote of coming upon two roads that diverged in a wood, and was sorry he could not travel both. Not only can quantum processes take both roads at once, they can interfere with themselves in doing so.
The research team, working at UC Berkeley and at Berkeley Lab's Advanced Light Source, has shown that inelastic light scattering can be controlled by controlling interference between the intermediate states between photon absorption and emission. Manipulating that interference has enabled new kinds of quantum control of chemical reactions, as well as of "spintronic" states, in which not charge but the quantum spins of electrons are affected. Strongly enhanced Raman scattering can be a boon to nanoscale materials research. Hot luminescence is potentially attractive for optoelectronics and biological research, in which near-infrared tags – even weak ones – could be very useful.
"Likewise the phenomenon of hot electron luminescence, because it immediately follows excitation by a probe laser, could become a valuable research tool," says Wang, "particularly for studying ultrafast electron dynamics, one of the chief unusual characteristics of graphene."
