Two Women Test Their Mettle in 'The Wicked City' [REVIEW]
January 4, 2018 by Heather Fink 3 Comments
Two women from different eras are linked by a very special place in Beatriz Williams' The Wicked City. (Photo courtesy Pexels)
When a modern woman is forced to start life anew, she discovers an unexpected link to the past in her new home. How will she balance her newfound connection to a freespirited woman from the Jazz Age with the woman she has always known herself to be? Find out in Beatriz Williams' The Wicked City.
When Manhattanite Ella Gilbert discovers that her husband has been living a double life, she is devastated. Soon she walks out and finds a place of her own in Greenwich Village, far removed from the SoHo apartment she shared with her philandering hubby.
There she encounters Hector, the handsome musician who lives upstairs. He regals her with tales of their building's storied past, telling her how it once served as a speakeasy during the Roaring Twenties.
Among the people who frequented the joint back in 1924 is Geneva "Gin" Kelly, a redheaded Maryland flapper. One night she got caught in a raid by Prohibition enforcement agent Oliver Anson, who then enlists her to help him catch her stepfather, one of the biggest bootleggers in Appalachia.
The alliance between the flapper and the Revenue agent not only rattles Manhattan society, but it ultimately lays bare scandalous secrets that are even shocking to Gin.
As Ella digs deeper to unravel this story, she discovers a familial tie to the freespirited redhead and realizes just how powerfully Gin's legacy will impact her own life.
Those of you who read along with me on a regular basis know that historical novels aren't usually the first thing I tend to read. Those are usually the books on Jathan's night stand. So it takes a truly captivating writer to draw me into such a book. But Beatriz Williams has a real knack for writing an immersive novel that fascinates and doesn't get bogged down in dry details better suited to a collegiate history course. In fact, with The Wicked City, she has crafted a rich story filled with fascinating characters readers will come to love.
What makes this story truly unique, however, is how a seemingly innocuous basement transforms into a 1920s speakeasy every night after midnight. Like Ella, readers will find themselves intrigued by the beautiful music and laughter emanating from the depths of the residential building in the middle of Greenwich Village.
Using sensory detail, riveting period history and pure storytelling genius, Williams draws us into the lives of these two disparate women, and readers won't be able to resist turning pages as they seek to understand the connection between them.
The Wicked City is a vibrant story that readers will undoubtedly connect with emotionally and which will ultimately capture their imaginations. Using unforgettable characters and dialogue that at times makes us laugh out loud, this is one historical you'll be glad you didn't pass by.

The Superpower of The Internet in The Hands of Entrepreneurs
This article is written by Mohammad Eslim, a Contributor Author at Startup Istanbul.
Teruhide Sato was a founding member of the Japanese arm of CyberCash, a U.S. online payment company (now known as Venus), and a joint venture with SoftBank Corporation. During this time, in 1997, Teru was studying at the Faculty of Policy Management, Keio University. In 1999, he was co-founder of BEENOS (formerly known as netprice.com), a global internet and e-commerce business incubator.
Aurore Belfrage is a tech entrepreneur, investor, and a partner at EQT Ventures with a specific focus on Artificial Intelligence and GovTech. She is a syndicated columnist with leading Swedish daily Svenska Dagbladet (SVD) and a contributor to POLITICO. She writes on issues at the intersection of geopolitics, ethics, governance, labor and future of work.
Aurore Belfrage and Teruhide Sato were special guests at Startup Istanbul 2015, where they had a fireside chat on business.
Just in the last century, not anyone has predicted let alone imagined that we can start, run, or scale a business across the continent from the comfort of our homes. That was the internet, the superpower of the eighties.
This power has moved rapidly in the world's everything. Every fiber, every bit of data is now on the world's wide web stored in these small networks connecting into a huge network called the internet. Now the world has the same access to the world's data and every knowledge a human came to is recorded and under the use of our very own fingertips, can you imagine how resourceful is that?!
Yet we are still far from the significant effect it had on the world's business whether in growing it, scaling it into a world's leading business like Netscape which is now owned by Microsoft. Or in starting your own business using the internet. It's better to understand how much of an affect the internet had on our life when you look at what a person can do by only using his smartphone and an internet connection.
What we consider as the power of the internet is the power shift it made towards the small guys and individuals' SMEs and we are not talking about the big guys who already have their own place in the market. I think that for a fact the beauty of a marketplace is not only in the product marketplace but also in the service marketplace, Uber can be also considered a wonderful marketplace on the light of it fostering small entrepreneurs to make more money if they tried to.
In fact, it's believed that those businesses can have exponential growth opportunities because it creates jobs, makes wealth, brings more prosperity and creates a network effect that is a great spot a lot of owners and investors focus on when they are going for investments.
Another point very important for entrepreneurs going into a small businesses is marketing, mostly in the Middle East it's considered an afterthought, they think that once they grow into the company they want and have the capital they raised to buy advertisements instead of understanding the emotional need they are creating and how to create marketing around that.
Those entrepreneurs in these new markets have grown from zero ground into a self-made small business of their own. If they are seen in need of coaching and training then it's fine as long as you don't dictate how they work or decide on their behalf and always remember they are entrepreneurs who popped up from the ground.
For example, an entrepreneur has launched his business in Myanmar, which is a kind of an isolated country, and his business has scales in these hard conditions and found investments from investors out of his country due to his thoughtfulness in using his resources- especially the internet, when he 'somehow' raised money and 'somehow' he was able to start his businesses.
These entrepreneurs, who are sharing the same opportunities, building similar businesses or facing the same conditions and problems, even if they are of different countries are put together as a method in order to exchange ideas and suggest what are the best solutions and plans to put such a powerful resource, meaning the internet, into use with suitable marketing techniques to reach the best result they could so they can finally enter the competition with the giants.

Kalpvriksh (The Wish Tree)
Thanks to Aung for bringing this big news to my attention. Shabana Azmi is in a kids' film called Kalpvriksh, directed by Manika Sharma. The film looks like it will be ready for release later this year.
The film's official website offers just a little information but it sounds like a very interesting project, potentially very enchanting and delightful. Here's the basic outline of the story, from the website:
KalpVriksh – THE WISH TREE is a magical, inspirational and an extremely entertaining story of five children in a hill-station who come together to save their 'wishing tree' (KALPVRIKSH) from being cut by vested interests. The film is extremely lively, entertaining, endearing and engrossing so that the underlying message to protect trees and environment is seamlessly driven home.
Also piquing my interest is the description of the films songs, which sound they have very thoughtfully crafted and lush visuals:
The Earth song is a colorful collage of images to tell the story of the Earth's evolution. As we travel over snow capped mountain peaks to gushing waterfalls and rivers, pupae turn into butterfly and a giant dragonfly flaps its wings across the sky over a dense tropical forest.
Dhanua's dhaba song is his fantasy on the other side of life, where his abusive and exploitative owner, Shankar dada transforms into a sorrier version of Dhanua in rags and Dhanua becomes the Don (the underworld King) of the dhaba, flashing a white three piece suit and a red shining car. This song is in theatrical genre.
Nikita's concert song on stage as a rock-star is complete showbiz. It's the opening song of the film and resembles a Michael Jackson concert in which the fans are fainting with awe and adrenalin is running high.
The celebration of the tree song is vibrant and has the raw energy of nature. It throbs with life. The tree sways from side to side and dances, shivers and gurgles like a baby with the children. The Wishing tree is happy to come back to life after thousands of years with the love and faith of the children.
KALPVRIKSH is a very visual film. All the scenes in the film are color-coded, they fall within a certain scheme of colors according to the mood and inner journey of the characters. For instance Sean's room is blue, reflecting his state of mind. He misses his father constantly.
The cast is also listed on the website, and in addition to Shabana ji includes Saurabh Shukla, Makrand Deshpande (who was so wonderful in another kids' movie that Shabana ji was in, Makdee), and others, as well as a guest appearance by Shah Rukh Khan. I am very excited to hear more about this project and I will of course keep you posted. Between this one and Sorry Bhai, the second half of 2008 should be a good one for Shabana films.

With any health condition, support and treatment are the two things that all patients seek.
And in most cases – but not all – treatment usually includes some form of medication.
But one of the challenges with medication is that they aren't always effective, and some that do help with certain symptoms, bring on other challenging side effects.
This is even the case with drugs that are prescribed for the various forms of dementia.
A new study, which was published in the Journal of the American Geriatrics Society, looked it to the safety and effectiveness of four different cognitive enhancers that are commonly used by people living with Alzheimer's disease.
These cognitive enhancers are usually taken to enhance concentration, memory, alertness and moods.
"Alzheimer's dementia is the most common form of dementia…and most people who have moderate to severe Alzheimer's will be on these medications," said Dr. Andrea Tricco, the lead author of the study.
Though there have been reviews on the use of each of these Alzheimer's drugs in the past, this is the first research that has ever compared and ranked them based on safety and effectiveness.
The research particularly focussed on each drug's' effectiveness in patient outcomes, which included cognition, function behaviour, global status, mortality, serious adverse events, falls, bradycardia, headache, diarrhea, vomiting and nausea.
What the research found was that donepezil was most likely to improve cognition in people with Alzheimer's across all effectiveness outcomes, including cognition, behavior and overall health – but there was a catch.
People who took donepezil experienced severe side-effects such as nausea, vomiting and diarrhea.
However, donepezil was also the only cognitive enhancer that reached the "minimal clinically important threshold" – what this means was that it made enough of a difference that changes were seen on the Alzheimer's Disease Assessment cognition scale.
The study looked at 142 different trials of the four commonly used cognitive enhancers, between 1996 and 2015, which were either administered alone or in combination. In total there were 33,889 patients across these 142 trials.
The data analysed showed that there was no significant risk of serious harm, falls or reduced heart rate was associated with any of the four medications.
The researchers warned that though the drugs appear safe, their results must be interpreted cautiously because trial participants may have less comorbidity and fewer adverse effects than those treated with these drugs in clinical practice.

Kim Dotcom can be extradited to the US, New Zealand court rules
By James Griffiths, CNN
Published 11:20 PM EDT, Wed July 4, 2018
Kim Dotcom has been fighting extradition to the United States for years.

Internet mogul Kim Dotcom has lost another fight in his epic legal battle to avoid being extradited to the United States.
An appeals court in New Zealand on Thursday rejected Dotcom's attempt to overturn an earlier ruling which said he should face criminal charges in US, saying Washington had made a "clear prima facie case to support the allegations that the appellants conspired to, and did, breach copyright willfully and on a massive scale for commercial gain."
Dotcom is the flamboyant founder of file-sharing site Megaupload, which was shut down by the US government in 2012. He was arrested soon after by New Zealand police who descended on his luxury mansion in Auckland in two marked helicopters, and had to cut their way into a locked safe room to reach him.
The decision whether to extradite Dotcom now rests with New Zealand's Justice Minister Andrew Little, however Dotcom has indicted he'll apply for leave to appeal Thursday's ruling at New Zealand's Supreme Court.
Along with three co-defendants, Dotcom was indicted by a US grand jury on a range of charges including conspiracy to commit racketeering, wire fraud, conspiracy to infringe copyright on a commercial scale and money laundering.
They deny the accusations and have been fighting hard against extradition, arguing that Megaupload was simply a file-sharing website and that they shouldn't be blamed for what others were uploading to it.
Three New Zealand courts have now ruled against them, throwing out that argument and claims that they couldn't be extradited on charges of profiting from copyright infringement because it is not a crime in New Zealand.
While the Court of Appeal held that "double criminality" was required for an extradition offense, it said that "we are satisfied that New Zealand law permits extradition for copyright infringement in the circumstances of this case."
"The appellants are accused of conduct that, if proved, would establish extradition offenses in New Zealand law," the court said.
Dotcom also lost an attempt at the US Supreme Court to recover $40 million of assets seized by the government.
Kim Dotcom leaves with his girlfriend Elizabeth Donelly following his extradition appeal at the High Court in Auckland on August 29, 2016.

New Zealand's Justice Ministry declined to comment on the ruling Thursday, however under the country's Extradition Act, Justice Minister Little has final say on the matter.
Ira Rothken, Dotcom's US-based lawyer, said on Twitter the defendants were "disappointed with today's judgment by the NZ Court of Appeal."
"We have now been to three courts each with a different legal analysis – one of which thought that there was no copyright infringement at all," he said. "We will seek review with the NZ Supreme Court."
We are disappointed with today's Judgment by the NZ Court of Appeal in the @KimDotcom case. We have now been to three courts each with a different legal analysis - one of which thought that there was no copyright infringement at all. We will seek review with the NZ Supreme Court.
— Ira Rothken (@rothken) July 4, 2018
Per New Zealand law, only the Supreme Court decides which cases it will hear and Dotcom's legal team will now have to apply for leave to appeal.
In a statement, Dotcom said his legal team was "confident that the Supreme Court will hear the appeal given there are such significant legal issues at stake."
My statement about the disappointing judgement by the NZ Court of Appealhttps://t.co/7NFqGoSWIl
A judgement in complete denial of the legislative history and intention of the Copyright Act. Therefore it has the value of toilet paper. We will now appeal to the Supreme Court.
— Kim Dotcom (@KimDotcom) July 5, 2018
He said the Court of Appeal judgment was "in complete denial of the legislative history and intention of the Copyright Act. Therefore it has the value of toilet paper."
"The precedent set is concerning and has ramifications in New Zealand outside my case," Dotcom added. "The decision exposes Internet Service Providers to criminal liability for the misuse of their services by users, as is claimed against me."
US law is heavily weighted in favor of copyright holders, and has been criticized for stifling innovation and harming consumers, and for exporting US copyright regulations to other countries through free trade agreements.
Washington has also gone aggressively after file-sharing websites, with multinational cases against Kickass Torrents and The Pirate Bay. Defenders of the site point to the fact that they merely facilitate breach of copyright by sharing links to peer-to-peer torrent downloads, and do not actively host any protected files.
CNN's Jethro Mullen contributed to this report.

De Facto No-fly Zone in the Works to establish Brookings-prescribed "Safe Havens."
NATO has approved of stationing US-made Patriot missiles along Turkey's border, for what it claims is "defense." Over the past two years Syria has been fighting terrorists armed, funded, and equipped by NATO, of which Turkey is a member. Turkey has admitted its role in harboring and providing logistics for foreign fighters flooding across the border into Syria, many of whom are confirmed members of Al Qaeda. Despite this, Syria has gone through extraordinary lengths to avoid a confrontation with Turkey.
Image: A Patriot missile system. NATO Source Alliance News Blog reported on November 4, 2012, "Turkey plans to officially request NATO deploy a Patriot missile defense system in its territories as a security precaution against a potential large-scale military offensive from Syria as Syrian shelling on the border raises tensions." In reality, US officials have admitted the purpose of the missiles are to impose a no-fly zone over northern Syria.
Turkey's military has confirmed further air strikes against Kurdish rebel bases in northern Iraq.
It said nine attacks were carried out by Turkish aircraft on hideouts of the Kurdistan Workers Party (PKK), mostly in the Qandil region.
Last Wednesday the military said it had carried out similar strikes, a day after eight Turkish soldiers and 26 PKK rebels were killed in clashes.
"Today NATO agreed to augment Turkey's air defense by deploying Patriot missiles to Turkey. Turkey has asked for NATO's support and we stand with Turkey in the spirit of strong solidarity," said NATO Secretary-General Anders Fogh Rasmussen.
It appears then that the stationing of Patriot missiles along the Turkish-Syrian border is, in part, a means to give Turkey assurances of impunity as it continues facilitating increased, overt NATO aggression against Syria.
The West's diplomatic manipulation has failed. And because the Brookings report found considerable complications with conducting a Libya-style air campaign over Syria, (because Syrian forces are not isolated and exposed in the same manner as Libyan government forces were) it was determined that while significant damage could be accomplished versus the Syrian military from the air, it would not guarantee regime change and may lead to the necessity for the West to either "fold" or "double down with a ground invasion" (page 11).
It appears then, with the deployment of Patriot missiles, the West will try to salvage the best of both options – creating a safe haven in the north of Syria by creating a no-fly zone, but without flying sorties over Syrian territory.
Of course McCain fails to disclose that the extremists he "fears" pouring into Syria, are primarily from the very city of Benghazi he cited, a city he and the late US Ambassador J. Christopher Stevens personally helped establish as a region-wide terror-hub.
I think Patriot missiles – now the Germans are moving some patriot missiles under some kind of weird circumstances but at least they are coming into Turkey. Or we could give them a limited number, a controlled number of MANPADS. But primarily I think it would just be a Patriot installation. Pilots are not going to fly into certain death. I don't care how brave they are. And you shoot down one or two of them, they're not going to fly there again. They may like Bashar al-Assad, but they like to live a little more.
McCain would continue by admitting the Turkish government does not have the support of its people in supporting NATO's attempt to implement regime change in neighboring Syria.

The Shell V-Power Racing Team today unveils a special Indigenous livery for the upcoming Darwin Triple Crown. The Shell V-Power Racing Team is dedicated to the Racing Together programme that's designed to give 12-to-18-year-old Aboriginal and Torres Strait Islanders an opportunity to pursue a career in motorsport as a driver or a member of a race team.
The Shell V-Power Racing Team is a strong supporter of the programme. Ryan Story, the Team's Chairman and CEO is a director of the Racing Together board, while Viva Energy the exclusive licensee of the Shell brand in Australia, recently announced a new three-year partnership with the programme. Braedyn Cidoni is the designer of the Supercar livery and a Racing Together team member.
"The opportunity to highlight Racing Together and its objectives at the Darwin Triple Crown by way of an Indigenous livery supported by all of our partners and put together by Braedyn, who is the Racing Together race driver, is something of a remarkable story," said Story.
"I am very proud to be associated with the Racing Together organisation as a director, and what ties everything together for me is that Viva Energy, our major sponsor, is also a significant supporter of the project.
"We're partners in racing, and we're partners in business. The opportunity to raise awareness and to increase involvement in both STEM and motorsport for young Indigenous Australians is something that we should all aspire to."
The partnership between Racing Together and Viva Energy ties in closely with the energy company's vision for reconciliation as a nation where Indigenous people have equal and equitable opportunities to reach their destination. Viva Energy aspires to contribute to a society that is enriched by cultural diversity.
Seventeen-year-old Cidoni is thrilled to not only be the driver for Racing Together but also to have designed the Supercar livery. His work was inspired by artist Allison Millcock's "Turtles Crossing Cultures".
"While Allison's art represents her longing to connect with her ancestors, I used the turtle to highlight the environment and the wildlife that we need to protect and added the snake to represent the fierceness and power behind the Racing Together team," said Cidoni.
"I have always wanted to be a race car driver, and the Racing Together programme has given me the opportunity to do that. I couldn't believe I was selected out of everyone to be the driver.
"Our team has many different roles like engineer, mechanic and social media, and everyone is so happy to be part of the team – we've bonded, and all become really good friends."
The Shell V-Power Racing Team Indigenous livery can be seen on track at the Darwin Triple Crown, 18-20 June.

Detailing the process of evaluating the final marks, the minister said: "While computing the final result, the average of the three best theory marks of Class-10, 30 per cent weightage for Class-11 theory and 40 per cent weightage for Class-12 theory will be taken. Full marks of practical are given to students."
Earlier in the day, the CBSE submitted its evaluation criteria for awarding grades/marks for Class 12 exams before the Supreme Court.
The Council for the Indian School Certificate Examination (CISCE), however, said that it would consider the performance of students for the last six classes.
For Class 10 and 12, marks in the best of three from five papers in term exams will be considered. For Class 12, marks obtained in the unit, term and practical will be taken into account.
The Supreme Court has posted hearing on the matter for hearing on June 21.

Q: Uninstalling VS 2013 Express after installing VS 2013 Community and CUDA I am learning about GPU Programming using CUDA and I just realized that VS Express does not support plugins. I have installed VS 2013 Community and I was wondering if it is safe to uninstall VS 2013 Express after I have installed community and CUDA. Will doing such a thing 'break' anything ? I am only decent with programming so I have no idea about paths and environment variables and what not. Will my old projects still work if I launch them with VS community ?
I am aware of this thread Is it safe to uninstall VS Express after installing VS Ultimate? but was wondering if uninstalling will affect any paths or so.

A: In these cases it's safest to repair the edition you want to keep after a deinstallation. While the Visual Studio installation itself will probably survive, other components, such as Windows SDKs and Targeting packs may get damaged.
First uninstall the Express edition(s) and then go to Programs and Features to repair the Community Edition.

Work starts on Preston indoor skate park
Fit out work has started on a 15,000 sq ft warehouse property in Preston; transforming it into an indoor skate park and youth centre.
The premises, located on School Street, just off Bow Lane, can be accessed just off Ringway and is due to open early in 2011.
A café, indoor sports shop, and facilities for local bands are also included in the plans.
The property was previously occupied by graphic designers Format Imagining but has since been let by Herbygreen Properties to Northern Extreme Parks for ten years for an undisclosed sum.
The facility will include a variety of ramps for skateboarders, BMX bikers and in-line skaters. Initial internal demolition work is now complete and building contractors are due on site this week.
Developers behind the park are also hoping to link up with local charities, youth groups and youth workers who may want to use the venue when the park is not running.
Mark Harrison, surveyor at Robert Pinkus & Co, who acted on behalf of the landlord, said: "It has been a long process to finalise the lease but it has been well worth the wait as the centre promises to be a fantastic boost for the city's youth and community. We wish the new tenants every success in their new venture."
Northern Extreme Parks has so far managed to raise £100,000 through grant cash of the £140,000 needed to refurbish the property.

Since I have been cooking, I am always looking at ways to make things from scratch. I'll admit that I am not one who is constantly flipping over a box or packet, looking to see what all of the ingredients are, but when I do, I get a bit appalled. Try it once. First check out all of the ingredients that make up, well, for this example, taco seasoning, or better yet a box of hamburger helper. Now granted, in this case, taco seasoning only has a few things that bother me, such as ingredients of citric acid, potato starch, and whey, but you know where I am coming from. My point is that if you can make it yourself, and it tastes spot on, and better yet, you know what you are putting into it, than all the better.
A couple of things to note here. First, I can never find taco seasoning in bulk at the store, and that bothers me. Yes, I do admit that I have purchased plenty of taco seasoning packets in the past, but to tell you the truth, I have never been impressed with them, and when we are making tacos or nachos on a weekly basis, well, heck, I went out and came up with my own batch of homemade taco seasoning. It's spot on in flavor, makes a bunch so you have plenty to store, and it doesn't use citric acid or potato starch. Go figure.
That's it. Most if not all of us already have these spices in our cupboard, and when I experimented with the flavor profile of taco seasoning, I knew this combination would work out just fine, and it did.
Now every year I create a spice blend for some of my family members, work colleagues, and my blog followers, and what I recently learned from the folks at the Spice House in Milwaukee, is that when making a blend, it is important to mix the ingredients, like 1,000 mixes. Yes, that's right. Typically I would just throw everything in a large bowl and mix it about 100 times, but who knew I was doing it all wrong. So with any treatment, I mixed this one about the same.
Add everything to your mixing bowl, and if you have a KitchenAid mixer use it. Mix around 1000 times. This is great exercise for you or your child should you not have a mixer.
When you are finished, pour into an airtight, sealable container, and store in a cool, dark cupboard. I used some with some cooked meat the last time we had taco Tuesday, and everyone devoured the meal. We all know what that means. They were hungry, and there were no complaints with my flavor profile which means I got it right.
So when you have the opportunity to make things from scratch, give it a shot. You'll be happy knowing what was put into a recipe, and not questioning things like citric acid and whey. Hope you enjoy!
When you are finished, pour into an airtight, sealable container, and store in a cool, dark cupboard.
Good mix. I have been fairly successful in following ingredient list from Penzeys for their blends. In some cases, it is better to just order the blend if it has esoteric ingredients that you don't normally use.

Q: how to normalize value in neo4j cypher Given the set of results, I would like to normalize one value.
Example of ideal world query:
match (c)<-[:WORKS_FOR]-(u)-[:KNOWS]->(s)
where s.label = "Test"
with u as users
match (users)-[com:SEND]-(otherUsers)
with  users, sum(com.count) as messages
return users, messages / max(messages)

How to I get the max(messages) from across the users? UNWIND maybe?

A: We can improve this one a bit.
For one, you'll want to use at least one label here, so you avoid performing all node scans. Hopefully you're using labels when creating your nodes. If not, definitely start, unlabeled nodes will be non-performant for use in most queries, since you'll be using all node scans.
Also, for fast entry into the local graph, a label on s would be helpful, and an index on that label and its label property (which isn't the same as an actual label, just so you're aware).
Next, if you want to ensure a node has at least one relationship, it's better to use a WHERE for that rather than including it in the match. This can also reduce cardinality issues (say in case a user works for more than one company), which could multiply your results and the amount of subsequent work (as well as throw off other parts of your query).
As for how to aggregate max(messages) across all users, you'll need to aggregate the other variables as well, which is a little annoying, but no way around it.
Also, I prefer using singular for most variables, and only use plurals for collections, that can help avoid confusion.
Here's an example with the changes provided (assuming s is also a :User and that there's an index on :User(label)):
match (user:User)-[:KNOWS]->(s:User)
where s.label = "Test" and ()<-[:WORKS_FOR]-(user)
match (user)-[com:SEND]-()
with  user, sum(com.count) as messages
with collect({user:user, messages:messages}) as usersInfo, 1.0 * max(messages) as total
unwind usersInfo as userInfo
return userInfo.user as user, userInfo.messages / total as percentage


The Isle of Stone tackles a key episode from Thucydides' History of the Peloponnesian War: an Athenian naval force probing the coast of the Peloponnese set up a base that was surrounded and attacked by Spartans and then surprisingly managed to turn the tables on their foes. The Athenian victory led to a promising pause in the fruitless war between Athens and Sparta, a truce Athens herself would end by embarking on a fatal expedition to Syracuse. The novel opens decades earlier with an account of the disastrous earthquake that struck Sparta in 464 B.C., then for a long time flashes back and forth between the childhood struggles of two brothers born to a Spartan survivor of that disaster, and to the later catastrophe they face on the island of Sphacteria in 425 B.C.
Nicastro's story reveals some unpleasant truths about the Spartan system from the viewpoint of characters raised in that system and capable only of a few cloudy intuitions about its flaws. But he tries to tell a story without benefit of a main character who is truly sympathetic. That's a tricky task, and Nicastro lacks the literary skill that might have led to full success. The result is a novel that's impossible to recommend for the general reader who wants a well-crafted tale with a fair share of likeable characters. It also lacks the authorial voice and command necessary to produce real tragedy.

\section{Introduction}
One of the most intriguing aspects of the collective behavior of a system of  self-propelled (active)
particles (SPP) \cite{hydroactive}, is that the  motion of each individual particle can cause
an organized ("collective") motion of the SPP system as a whole. At high concentrations of SPPs,
the described collective motion is known to occur in systems of active colloids that form regular patterns
termed "active crystals" in \cite{LowenPRL1}. The presence of active drive makes the properties of the
described "active crystals" very different from  crystals formed by ordinary "passive" colloids.
In particular, self-propulsion of colloidal particles can significantly lower \cite{LowenPRL2,LowenPRL3}
the concentration threshold of the entropy-driven  clustering relative to that observed in
the system of passive colloids.
Moreover, an additional energy associated
with the  individual motion of the SPPs can be consumed not only by shifting the crystallization point of
the SPP system, but also by inducing the organized motion of the SPPs. In this scenario, the orientational interactions between
the individual SPPs can cause an essentially non-equilibrium state, where the SPP system moves in a direction chosen by symmetries
of the patterns formed by these SPPs. The described states of collective motion have been observed experimentally in many
relevant biological
systems, ranging from  bacteria colonies \cite{micro,micro1,micro2,micro3} to the flocks of
birds \cite{birds, TonerTu}, which explains the high interest in
understanding the physical effects underlying these states. Despite
essential theoretical progress \cite{hydroactive} in the field achieved over the last decade, many aspects of the described collective
behavior of SPPs still remain rather obscure. One of such key aspects
addressed in the present work, is the relative significance of the tendency of SPPs to form patterns and of the orientational relaxation
of their velocities for the formation of moving and resting steady states of the SPP system.

By making use of the minimal model described below, we  demonstrate that the orientational relaxation of the
SPP velocities is the main factor playing in favor of suppressing the collective motion of the SPPs caused by their self-propulsion.
More specifically, we will show that the transition between
the observed moving ordered state, resting ordered state and disordered (homogeneous) state can be induced solely by changing the rate of the orientational
relaxation of the SPPs. According to our exact results described below, the individual motion of SPPs  {\it always}
causes a tendency towards collective motion of the whole SPP system.  In this sense, there exists no single threshold magnitude
of the active drive that delineates the regimes of moving and resting states. The main factor that suppresses the collective motion of the SPPs
is a sufficiently quick orientational relaxation of the local orientation of the SPP velocities quantified by the "polarization" field
$\mathbf{P}(\vec{r})$.

\section{The model}
In order to rationalize the described interplay between the tendencies of the active SPP system to the crystallization and collective motion,
it is instructive to study a modification of the well-established colloid crystallization model that would adequately account for the active
drive of the colloids. A minimal model of that type has been recently developed in \cite{LowenPRL1}, by combining the Phase-Field-Crystal
(PFC) model \cite{ElderGrantPRE,UwePRE,EmmerichLowen} and Toner-Tu (TT) \cite{TonerTu} approach describing the kinetic flocculation with
the effect of the
orientational order of flocks taken into account. Owing to its transparency and simplicity, this model provides an excellent framework
for studying the complicated interplay between the spatial and orientational ordering of the SPPs. Although this pioneering work provides very
useful insight  into the nature of the collective behavior of SSPs, it does not give a systematic account for possible transitions between
moving and resting  states of SPPs depending on the relative significance of the involved effects. In the present work, we
use a slightly modified version of the described model with the objective to construct the exact "phase diagram" describing all the possible
collective states of the SPPs,
as well as the transition boundaries between them. In addition, we  investigate, both analytically and numerically, the dependence of the
velocity of the collective motion on the involved parameters. As we demonstrate below, this detailed investigation leads to
a new understanding of the relative role of the involved effects (e.g. pattern formation and rotational diffusion) in the formation of the
observed moving and resting patterns in the SPP system.

Having implemented the above outlined strategy of combining the PFC and TT approaches,  we employ
the above outlined idea of describing the correlations between the density $\rho(\vec{r})$ and orientational $\vec{P}({\vec{r}})$ fields
with help of coupled PFC and TT equations. Note that the main quantity of interest $\rho$ termed "density" in the above
for the sake of convenience,
is assumed to have no limitations with respect to the domain of values it can assume. Similarly as in the standard PFC approach, this quantity
should be understood as an order parameter (e.g. a density excess over the critical density).  Therefore, $\rho$ can assume,
in particular, negative values. Note that  additional limitations
on the domain of possible values of $\rho$ imposed by specific physical conditions can be easily incorporated into
the described model without causing a loss of its generality. One such possibility arises from properly defining the average density
$\bar{\rho}$, considered an input parameter of the model.

For the sake of tractability, we use a simplest possible form of the  dynamical equation for the  vector quantity   $\vec{P}$,
termed "polarization" hereafter,
describing the orientational order in the field of the SPP velocities. This equation of the form
\begin{equation}
 \label{1}
\frac{\partial\vec{P}}{\partial t} =  -\tau^{-1}\left(1-\gamma\nabla^2\right)\vec{P} - v_0\vec{\nabla}\rho
\end{equation}
has been first empirically obtained in \cite{Fily}, by making a comparison with the results of the simulations for  SPP disks.
Note that the terms on the right hand side (r.h.s.) of Eq.(\ref{1}) containing $\vec{P}$ can be obtained by dropping
the non-linear terms in the original TT equations. The generalization of Eq.(\ref{1}) containing additional non-linear terms
has been independently obtained in \cite{LowenPRL1}.
Coupling of the orientational order to the
density field is described by the last pressure-like gradient term in the r.h.s. of Eq.(\ref{1}) featuring the constant
magnitude $v_0$ of the self-propulsion velocity of the SPPs. The coefficients $\tau^{-1}$ and $\gamma$  quantify,
respectively, the relaxation rate due to the orientational diffusion and significance of the spatial dispersion of the polarization.

Note that the simple diffusion equation for density $\rho$ used in \cite{Fily} is not suited for describing
the formation of periodic patterns of the SPP density needed to mimic the crystallization of SPPs in our approach.
In order to improve this feature of the model, critical for its applicability
to the case of active crystals under consideration, we follow  \cite{LowenPRL1} and employ the PFC
equation for the density $\rho(\vec{r})$ of the form
\begin{equation}
 \label{2}
\frac{\partial\rho}{\partial t} = \nabla^2 \left[\omega(\nabla)\rho + (\bar{\rho}+\rho)^3  \right] -
v_0 \vec{\nabla}\cdot\vec{P},
\end{equation}
where we have separated out the average density $\bar{\rho}$ for the sake of convenience. Here,
\begin{equation}
 \label{2.1}
 \omega(\nabla) = -\epsilon + \left(q^2+\nabla^2\right)^2
\end{equation}
is the $4$th-order differential operator with the only control  parameter $\epsilon$ (reduced deviation from the critical temperature), inherited
from the standard PFC model \cite{ElderGrantPRE,EmmerichLowen,Steinbach}. Recall that in this model the positive (negative) values of $\epsilon$
correspond to the
ordered patterned (homogeneous) steady states of the density field. The morphology of patterns formed at positive $\epsilon$ is determined by
the average
density $\bar{\rho}$. Note that the only difference that distinguishes the standard PFC equation from its modification in Eq.(\ref{2}) is the
last term in its r.h.s. describing the coupling of the density structure to the polarization field.

It is important to note an essential difference between the structures of the equations in Eq.(\ref{2})
and Eq.(\ref{1}). Eq.(\ref{2}) is a non-linear equation for the density coupled to  Eq.(\ref{1}) through
the linear coupling term $v_0 \vec{\nabla}\cdot\vec{P}$. Eq.(\ref{1}) is, in contrast, a linear differential equation,
which greatly simplifies the analysis of the coupled dynamics of the fields $\rho$ and $\vec{P}$. Specifically,
in the frameworks of the proposed linear model for the dynamics of $\vec{P}$, the effect of the orientational field on
the pattern formation and collective motion of SPPs can be fully understood in terms of the relation among the
relaxation rate  $\tau^{-1}$  and reduced self-propulsion velocity $v_0$. In the extreme case of quick relaxation of the
orientational field $\vec{P}$ ($q\tau v_0\ll 1$), the spatial structure of the polarization field $\vec{P}$ immediately adjusts to the
structure of the density field $\rho$ of the SPPs. Physically, this regime corresponds to sufficiently large undercooling, where
the local mobility of the SPP domains depends only on their density, so that the most "crowded" domains have the smallest local velocities.
In the symmetric density phases, the individual motion of the SPP domains moving in the opposite directions averages out,
thus resulting in the resting state. In this case, the orientational relaxation of $\vec{P}$
causes no qualitative difference in the spatial structure of $\rho$ relative to the predictions of the standard PFC
model. As will be shown in what follows, the described quick relaxation of $\vec{P}$  causes only a quantitative
correction to the PFC control parameter $\epsilon$ in Eq.(\ref{2.1}) that leads to a shift of the phase boundary separating the domains
of patterns and homogeneous SPP phase. In the opposite case $q\tau v_0\gg 1$ of slow orientational relaxation, a more complicated
response
of the density field to the orientational relaxation is observed. In particular, slow relaxation of $\vec{P}$ results in the occurrence of
steady states
in the form of moving patterns. In contrast to the former case of the quick
relaxation of $\vec{P}$, this case cannot be reduced to any modification of the PFC model.

\section{Linear stability analysis}
The above outlined qualitative picture can be rationalized by employing an analytical linear stability analysis of the simultaneous
Eqs.(\ref{1}-\ref{2}). The obtained analytical prediction for the phase-diagram of pattern formation
in the system of SPPs are found to be in perfect agreement  with that obtained from the numerical solution of the same equations. We attribute this good
agreement to the linear
character of Eq.(\ref{1}) that captures the effects of the orientational field on the density structure on the linear response level.

Linear stability analysis needs to be performed by taking into account the actual morphology of the patterns occurring in the SPP system
under investigation. The possible morphologies are determined (see Fig.1)  by numerically  solving
Eqs.(\ref{1}-\ref{2}) as described below. These morphologies are found out to be largely the same as those observed in the standard PFC model.
For the sake of brevity, we
do not discuss different morphologies (e.g. checkerboard and zig-zag lamellae morphologies) that have been observed by us only in the extreme
cases of
strong coupling $v_0\sim 1$ or for large values of  $\epsilon \sim 3$. Neither do we analyze non-periodic patterns that
occur as "metastable" states between the lamellae and hexagonal morphologies (see Fig. 1 c, d). It turns out that
the morphology of the patterns  affects neither  the collective velocity nor the shift in the crystallization temperature. This
observation  gives a rational for restricting our analysis to the cases of lamellae and hexagonal morphologies known from
the standard PFC model.

In addition to the well studied resting steady states occurring in the standard PFC, one needs to take into account the possibility
that the patterns can move with constant velocity $v$, which complicates the associated mathematical development.
The simplest observed one-dimensional morphology, the lamellae morphology (see Fig.~1~a,b)),  is comprised of  parallel stripes (rolls) that
show no spatial variation along their axes.
The structure of the lamellae morphology of a given periodicity $\frac{2\pi}{|\vec{k}|}$ can therefore be described by a single wave vector
$\vec{k}$ perpendicular to the stripes.  For the sake of simplicity, we chose to work in the coordinate frame associated with
the wave vector $\vec{k}$ pointing in the direction of the $x$-axis of this frame. With the described choice of the coordinate frame,
a set of equations given by Eqs.(\ref{1}-\ref{2}) reduces to two coupled equations for $\rho$ and $P_x$ with  $P_y = 0$. Periodic modes
of the density and orientational
fields corresponding to the lamellae morphology moving with velocity $\vec{v}$ can therefore be described by a linear
combination of the plane waves $\sim \exp{(\pm ik(x\pm |\vec{v}|t))}$ having different
amplitudes and wave numbers $k =|\vec{k}|$.
An important feature of the  fields
$\rho$ and $P_x$ that needs to be taken into account in the performed linear analysis, is the phase shift between these
periodic fields that can be elucidated by a comparison of the numerical results shown in Figs. 1a) and 1b). We describe this shift by
employing the following
forms of the fields $\rho\sim \cos{(k(x-vt))}$ and $P_x \sim \sin{(k(x+\Delta x-vt))}$. Substituting these expressions into
the simultaneous equations Eqs.(\ref{1}-\ref{2}), linearizing with respect to the amplitudes of  the fields $\rho$ and $P_x$,
and deriving the consistency conditions for the obtained algebraic linear homogeneous equations for the amplitudes, one arrives at

\begin{align}
 \label{15}
 (v^2-v_0^2 -v(k\tilde{\tau})^{-1} \tan{(k(\tilde{x}+\Delta x))})\tan{(k\tilde{x})}= \nonumber \\
(\tilde{\epsilon}-(k^2-q^2)^2)(vk-\tilde{\tau}^{-1}\tan{(k(\tilde{x}+\Delta x))}) ,
\end{align}
where $\tilde{\epsilon}=\epsilon - 3\bar{\rho}^2$, $\tilde{\tau}=\tau (1+\gamma k^2)^{-1}$
and $\tilde{x} = x - vt$. Note that due to the
presence of the gradient term in the operator
$\omega(\nabla)$ in Eq.(\ref{2}), the described linearization of Eqs.(\ref{1}-\ref{2}) always admits the additional
constant solution corresponding to the wave vector $k=0$. Hereafter, we omit this trivial solution that is inherent to
the  nature of the used "conserved" PFC equation that preserves the average SPP density.

Eq.(\ref{15}) admits the solution $\Delta x = 0$, $v = 0$,
\begin{equation}
 \label{4}
 \tilde{\epsilon} = v_0^2\tilde{\tau} + (k^2-q^2)^2,
\end{equation}
which describes the stationary (resting) steady state. It is important to note that
this case corresponds to the zero phase shift $\Delta x  = 0$. This observation quantitatively corroborates
the above qualitative consideration that the field of the polarization is in phase with the gradient of the density field
in the stationary steady state of the SPP system.
In this case, the solution to the linearized equations obtained from Eqs.(\ref{1}-\ref{2})  is fully determined by the dispersion
relation given by Eq.(\ref{4}).

In the case of non-zero velocities of the collective motion, Eq.(\ref{15}) reduces to the
explicit expressions for the dispersion relation $\tilde{\epsilon}(k)$, collective velocity $v$ and phase shift $q\Delta x$
of the form
\begin{eqnarray}
 \label{5}
 \tilde{\epsilon} = k^{-2}\tilde{\tau}^{-1} + (k^2-q^2)^2, \quad v^2 = v_0^2 - k^{-2}\tilde{\tau}^{-2}, \\
 \tan{(k\Delta x)} =kv\tilde{\tau}.
 \end{eqnarray}

The dispersion relations $\tilde{\epsilon}$ given by Eq.~(\ref{4}) and Eq.~(\ref{5}) determine the non-trivial values of the critical
wave numbers that
delineate the regions of stability and instability of the solutions of Eqs.~(\ref{1}-\ref{2}), corresponding to
the resting and moving steady states, respectively. According to these relations, the obtained solution of the linearized dynamical
equations
is unstable in a  band
of wave numbers in the vicinity of $k=q$. In the presence of  non-linear term $\sim (\rho + \bar{\rho})^3$
in the r.h.s. of Eq.(\ref{2}),
the exponentially growing modes, causing the instabilities,
become suppressed so that they saturate to a finite
limit with increasing the time. Similarly as in the standard PFC \cite{UwePRE}, this suppression results in shrinking
the described instability band to a single
critical wave number $q$ that corresponds to the only stable mode. Near the onset of the non-linear instability, one can
therefore expand the r.h.s. of Eq.(\ref{4}) and Eq. (\ref{5}) at $k=q$. Up to the leading order these expansions read,
\begin{equation}
 \label{6}
\tilde{\epsilon}_R = v_0^2\tau (1+\gamma q^2)^{-1}, \quad
\tilde{\epsilon}_L = q^{-2} \tau ^{-1}(1+\gamma q^2)
 \end{equation}
 \begin{equation}
 \label{10}
 v^2 = v_0^2 - q^{-2}\tau^{-2}(1 + q^2\gamma )^2,
 \end{equation}
respectively.

Note that the above calculation is valid only for the simplest case of the one-dimensional roll patterns.
In order to obtain the dispersion relation
and collective velocity for more complicated two-dimensional pattern morphologies, one needs to use a linear combination of the
considered roll solutions,
corresponding to symmetries of these morphologies. For the case of the hexagonal patterns shown in Fig. 1 e),f),
an appropriate  linear combination of the roll solutions, admitted by the linearization of Eqs.(\ref{1}-\ref{2}),  reads
\begin{equation}
\label{6.1}
 \sum\limits_{l=1}^{3} r_l\cos{(k \vec{k}_l\cdot \vec{\tilde{r}})},\quad
 \sum\limits_{l=1}^{3} p_l^{x,y}\sin{(k \vec{k}_l\cdot (\vec{\tilde{r}} + \Delta\vec{r}_l))},
\end{equation}
 where $r_l$, $p_l^j$ are, respectively, the amplitudes of the density field and the $j$th component of the  polarization  field,
$\vec{\tilde{r}} = \vec{r} - \vec{v}_l t$, and $k\Delta\vec{r}_l$ are the phase shifts of the polarization field.
 The vectors $\vec{k}_l$, associated with
 different roll modes that form hexagons upon interference, are given by $\vec{k}_1= \vec{e}_x$, $\vec{k}_2= (-\vec{e}_x +\sqrt{3}\vec{e}_y)/2$,
 and $\vec{k}_3= (-\vec{e}_x - \sqrt{3}\vec{e}_y)/2$, $\vec{e}_x$ and $\vec{e}_y$ being the position vectors associated with a chosen Cartesian
 coordinate frame. Note that $|\vec{k}_1|=|\vec{k}_2|=|\vec{k}_3|=1$. Applying the procedure used above for the case of a single roll solution
 to each of the exponential
 terms given in the r.h.s. of Eq.(\ref{6.1}), one arrives at a set of three consistency conditions that lead to an explicit expression for the
 dispersion relation, velocities $\vec{v}_l$ and phase shifts $\Delta\vec{r}_l$. The thus obtained dispersion relations $\tilde{\epsilon}(k)$
 prove to be the same
 as those given by Eq.(\ref{6}) for the one-roll solution in the cases of zero ($\epsilon_R$) and non-zero ($\epsilon_L$)
 collective velocities, respectively.
 The velocities of the rolls are obtained from the above consistency conditions in the form $\vec{v}_l=  v \vec{k}_l$,
 with  $v$ given by Eq.(\ref{10}). Eq.(\ref{6.1}) therefore describes  the three rolls, independently moving with the same velocity in the
 directions
 normal to their axes. Note that for the considered hexagonal morphology, the quantity $v$ describes the reduced
 temporal frequency $qv$ of changing  the hexagonal patterns in time, and has been called "velocity" only for the sake of unifying
 the description with the one-dimensional case. The phase shifts are obtained in the form $\Delta\vec{r}_l = \Delta x \vec{k}_l$ with $\Delta x$
 given by Eq.~(7).

Two important observations regarding the obtained analytical results given by Eqs.(\ref{5},\ref{6},\ref{10}) are in order here.
First,  the r.h.s. of the
expressions for the critical control parameter given by  Eq.(\ref{6}) does not depend on the
average density $\bar{\rho}$. Recall that parameter $\bar{\rho}$ in the PFC equation for the SPP density given by Eq.(\ref{2}),
is responsible for controlling the morphology of
the patterns. Therefore, the above observation speaks in favor of the statement, alluded in the introductory part, that
the shape of the boundaries delineating the steady states of the SPP system does not depend on the morphology of the SPP patterns.
The second important observation regarding Eq.(\ref{10}) is that the velocity $v$ of the pattern motion  does not depend on the control
parameter $\epsilon$. It is interesting
that according to the results of the numerical calculations, this property of $v$ proves to hold not only near the onset of
instability, but in the whole explored domain of values of the involved control parameters.

The derived expressions for the reduced control parameter $\tilde{\epsilon}$ and the velocity $v$ near the onset of
instability are the central results of the present work. In order to verify these analytical findings, we perform
isogeometric finite element analysis \cite{Hector1,Hector2} of Eqs.(\ref{1}-\ref{2}) over a wide
range of the parameters $\epsilon$, $v_0$,  $\tau$ and $\gamma$. In order to eliminate finite-size effects
we impose the standard \cite{Hector1} periodic boundary conditions and use a relatively large ($72.7 q^{-1}\times 72.7 q^{-1}$) simulation domain size.
We have "fixed"  the morphology
of the SPP patterns by giving appropriate values to the average density $\bar{\rho}$. Specifically, we have used the three
values $\bar{\rho} = 0.0; 0.2; 0.1$ that correspond to the lamellae (roll), hexagonal and "metastable" lamellae-hexagonal patterns,
respectively. The described patterns, obtained from the simulations, are shown in Fig.1. Note that the obtained patterns are found
to move or rest at the respective values of the orientational relaxation rate  $\tau^{-1}$ predicted analytically.
By fixing chosen values of the parameters $\bar{\rho}$, $v_0$ and $\gamma$ and varying the values of $\tau$ and $\epsilon$, we determine
morphologies  and velocities (if any) of the corresponding patterns formed by SPPs. As a result, we identify the phase boundaries separating
different regimes (e.g. moving and resting patterns) in the $\tau^{-1}-\epsilon$ plane. The results of this analysis are depicted in Fig.2-3.
As can be seen from these Figures, our simple analytical expressions given by Eqs.(\ref{5}-\ref{10}) provide a perfectly adequate prediction
for the boundaries between the possible steady states and the collective velocity of the SPP system. The determined steady states of the SPP system
and the transition boundaries between them are represented in the form of a "phase diagram" described in the next section.

\section{Resting and moving states of the SPP system}
Based on our analytical and numerical results, we have identified three different regimes of the qualitatively different behavior of SPPs:
homogeneous state,
moving patterns and resting patterns. Note that this result is in qualitative agreement with \cite{LowenPRL1}. Our more detailed analysis leads,
however,
to several essentially novel features relative to this previous work, critical for understanding the behavior of the SPPs. First of all, we emphasize
that the moving state of the patterns occurs for any non-zero magnitude of the self-propulsion velocity $v_0$ at sufficiently small values of the
orientational relaxation rate $\tau^{-1}$.
According to the performed analysis,
increasing the relaxation rate $\tau^{-1}$ at any given $\epsilon>3\bar{\rho}^2$ causes the transition from the "moving" to the "resting"  state
of the patterns.
The nature of this transition depends on the value of the control parameter $\epsilon$. Above certain critical value $\epsilon_c$, the described
moving-resting pattern ($M-R$) transition occurs directly, without crossing over the domain of the homogeneous SPP state. For $\epsilon<\epsilon_c$,
in contrast, increasing $\tau^{-1}$ causes a sequence of two transitions: (i) moving pattern-homogeneous state ($M-H$) transition  and
homogeneous state- resting pattern ($H-R$)
transition.
The critical value $\epsilon_c$ can be easily evaluated by determining the intersection of the dispersion curves $\epsilon_L(\tau^{-1})$ and
$\epsilon_R(\tau^{-1})$ described by the corresponding dispersion relations given by Eq.(\ref{6}). The result of this evaluation leads to an
incredible simple result $\tilde{\epsilon}_c = v_0 q^{-1}$, which gives excellent agreement with the numerical calculation (see Fig.2). In the
$\tau^{-1}-\epsilon$ diagram shown in Fig.2, the domains corresponding to the homogeneous state ($H$), resting ($R$) and moving ($M$) patterns,
are separated by the three different
phase boundaries $M-R$, $M-H$, and $H-R$. Analytical predictions for these  boundaries
are represented by the dash-dotted, solid and dashed curves respectively defined by the equations $\tau^{-1} = \frac{qv_0}{1+q^2\gamma}$
($\tilde{\epsilon}\ge v_0 q^{-1})$,  $\epsilon= 3\bar{\rho}^2 + \tilde{\epsilon}_L$, and $\epsilon= 3\bar{\rho}^2 + \tilde{\epsilon}_R$ with
$\tilde{\epsilon}_{R,L}$
given by Eq.~(\ref{6}). The scatter points in the diagram show the numerical results for the described phase boundaries.
In order to ensure a high quality of the verification of the obtained analytical expressions, the phase boundaries have been
determined numerically with the accuracy $\Delta\tau^{-1} = \pm 10^{-3}$.
As can be seen from Fig. 2, the described numerical calculations and analytical predictions for the phase diagram  show excellent
agreement. This allow us to conclude that the linear stability analysis of the coupled non-linear PFC-TT equations provides quite a
sufficient description of the transitions between the steady states of the SPP system.

According to the obtained phase diagram shown in Fig.2, in the case when the effect of the orientational relaxation is not sufficient to prevent
the SPPs from collective motion, the patterns move with the constant velocity $v$. It is instructive to investigate the dependence of
this velocity of the patterns on the involved parameters $\epsilon$, $\bar{\rho}$, $\tau$ and $\gamma$. Illustrative results of the
numerical calculations of $v$ in different domains of the control parameter $\epsilon$ are shown in Fig.3. As can be seen from this Figure,
the obtained numerical predictions are in a good agreement with the analytical expression given by Eq.(\ref{10}). Moreover, this expression
 proves to perfectly describe the numerically obtained dependence $v(\tau^{-1})$
in the whole investigated range of $\tau^{-1}$. Note that $v(k)$ in Eq.(\ref{5}), obtained from the linearized dynamical equations,
does not depend on the parameters $\epsilon$ and $\bar{\rho}$. The only approximation that is used to derive
$v(q)$ in Eq.(\ref{10}) from its "linear" counterpart $v(k)$ in Eq.(\ref{5}) consists in selecting a specific value of the wave number $k=q$
that corresponds to the only stable solution of the nonlinear equations. This approximation does not specifically rely on the expansion
near the transition boundary (i.e. at $\epsilon \sim \tilde{\epsilon}_L+3\bar{\rho}^2$), which explains the observed validity of
Eq.(\ref{10}) away from this boundary. In addition, $v$ given by Eq.(\ref{10}) does not depend on the parameter
$\bar{\rho}$, so that the magnitude of the velocity is not affected by the morphology of the patterns.

Further, for any $\epsilon > 3\bar{\rho}^2$ there exists a finite range
$0\le\tau^{-1}\le (\epsilon - 3\bar{\rho}^2)(\gamma + q^{-2})^{-1}$ where the SPPs experience a collective motion. The velocity of this motion
monotonically decreases with decreasing $\tau$ from the maximum value $v_0$ to the minimal value reached at the transition boundary.
An important feature of the obtained dependance $v (\tau)$ shown in Fig.3 is that it behaves in qualitatively different ways upon
approaching the phase boundaries corresponding to the $M-H$ and $M-R$ transitions.
In the domain of small control parameters $\tilde{\epsilon} < q^{-1}v_0$ corresponding to the $M-H$ transition,
$v$ monotonically decays to a finite
value that evaluates to $\sqrt{v_0^2-q^{2}\tilde{\epsilon}^2}$, as predicted by Eqs.~(\ref{6})-(\ref{10}) (see Fig 3a).
In the domain $\tilde{\epsilon} > q^{-1}v_0$, the velocity
tends to zero upon
approaching the $M-R$ phase boundary (see Fig 3b). In order to correlate the observed behavior of the pattern velocity $v$ with the structure of the
patterns, we have numerically calculated the root-mean-square-deviation (RMSD) defined as
$r_m (t,\tau) = (V^{-1}\int (\rho(\vec{r},t)-\bar{\rho})^2 d^2 r)^{1/2}$, $V$ being the area of the computational domain.  RMSD
describes the spatial dispersion of the SPPs at a given moment of time $t$. As can be seen from the results of the calculation of
the asymptotical values of $r_m (t)$ at  $t\to\infty$ shown by the squares in Fig.3, $r_m (\infty,\tau)$ shows just the opposite trend
relative to $v(\tau)$. Specifically, upon approaching the phase boundary, $r_m (\infty,\tau)$ tends to a finite value for
$\tilde{\epsilon} > q^{-1}v_0$, and it decays to zero for $\tilde{\epsilon} < q^{-1}v_0$.
\begin{figure*}

region (dotted), and the results of the numerical analysis. Inset of b) shows a zoom
depicting the behavior of $v(\tau^{-1})$ at the $M-R$ boundary.}
\end{figure*}

As can be elucidated from Fig.3 and our result in Eq.(\ref{10}), in the absence
of the rotational diffusion and dispersion ($\tau^{-1}=\gamma = 0$), the patterns move with the constant velocity $v_0$.
This collective motion is inherent to the individual motion of the SPPs with the same self-propulsion velocity $v_0$,
not affected by the above described "synchronization" of the local density and orientation  fields.
The occurrence of the rotational diffusion and dispersion ($\tau^{-1}\ne 0, \gamma\ne 0$)  plays in favor of  suppressing
this motion.  This suppression results in the  monotonic decay
of the velocity $v$ with increasing the rate of the rotational diffusion predicted by our result given by Eq.(\ref{10}).

The above described monotonic behavior of the function $v(\tau^{-1})$, which proves to be the same for the one-dimensional
roll patterns and two-dimensional hexagonal patterns, shows qualitative differences with its counterpart $v_m$ obtained
in  \cite{LowenPRE1} for the one-dimensional case. After adopting  the notations used in \cite{LowenPRE1} to
those employed in the present work, $v_m$ can be written as
\begin{equation}
 \label{11}
 v_m^2 = q^{-2}\tau^{-2}(1+q^2\gamma)^2 - v_0^{-2}q^{-4}\tau^{-4}(1+q^2\gamma)^4.
\end{equation}
The prediction for the collective velocity $v_m$ given by Eq.(\ref{11}) is depicted by the dashed curve and is referred to as
"MOL theory" in Fig.3. Note that according to \cite{LowenPRE1}, the validity of  Eq.(\ref{11}) "remains restricted
to the very close vicinity of the threshold for the onset of collective motion". Our numerical results, depicted in
Fig.~3 by triangles, corroborate this statement only for the case of the $M-R$ boundary (i.e. at $\tilde{\epsilon}>q^{-1}v_0$)
shown in Fig.~3b).  Comparison of the prediction of Eq.(\ref{11}) against our numerical results
makes it possible to establish quantitative criteria for the qualitative validity of MOL theory, to be expressed as
$\tau^{-1}>\tau_{max}^{-1}\equiv 2^{-\frac{1}{2}}q(1+q^2\gamma^2)^{-1}v_0$; $\tilde{\epsilon}>q^{-1}v_0$.
Outside of this range of its validity, an overdrawn application of  Eq.(\ref{11}) would lead to predicting an increase
in the collective velocity $v(\tau^{-1})$ as the rate of the rotational diffusion $\tau^{-1}$ increases, as well as vanishing
$v$  with vanishing $\tau^{-1}$. Both of the mentioned features are not observed in our numerical analysis.
In Fig. 3, we distinguish the regions of validity (invalidity) of MOL Eq.(\ref{11}) by depicting the corresponding parts of
the curve representing this equation by dashed (dotted) segments.
As can be elucidated from Fig.~3a), MOL theory does not cover the case $\tilde{\epsilon} < q^{-1}v_0$ corresponding to the $M-H$ boundary,
as this boundary is located to the left of the maximum of $v_m(\tau^{-1})$.  As is explained above,
our result for $v$ given by Eq.(\ref{10}) is free from the mentioned limitations as long as $k=q$ corresponds to the only marginally stable mode
of the spatial variation of the density. This fact explains the demonstrated validity of our results in a wide range of $\tau^{-1}$.

\section{Conclusions}
We have investigated the collective behavior of active SPPs described by their density and velocity orientation fields.
The three main effects are shown to influence the collective behavior of the SPPs, as follows:
(i) pattern-formation controlled by the parameters $\epsilon$ and $\bar{\rho}$,  being responsible for
the significance of
pattern-forming effect and symmetry of the pattern morphologies, respectively;
(ii) orientational relaxation and dispersion of the SPP velocities controlled by the parameters $\tau$ and $\gamma$;
(iii) coupling between the density and orientational fields controlled by the parameter $v_0$.
As our main result we have shown, both analytically and numerically, that the form of  steady states of the SPP system
primarily depends on the significance of the orientational relaxation (orientational diffusion and dispersion) of the SPP velocity field.
In the absence of quick orientational relaxation of the SPP velocities, the individual motion of the SPPs results in a motion of the system
in the direction of the shift of the polarization field relative to the density field of the SPPs.
With increasing significance of the orientational relaxation, the SPPs are forced to transit to either disordered or resting
ordered steady states, as is illustrated in Fig.2. Above a certain threshold magnitude of the orientational relaxation rate $\tau^{-1}(1+\gamma)$,
a spatial "synchronization" of the orientational field with the field of the SPP density gradients occurs. This synchronization
results in averaging out the velocities of the elementary SPP domains, thus suppressing their collective
motion.  If the significance of the pattern-forming effect
quantified through the parameter $\epsilon$ is not sufficient  to preserve the spatial structure of the patters in the whole range
of the relaxation rates, the transition to the homogeneous steady state occurs at $\tau^{-1}\sim \tilde{\epsilon}$. In the frameworks
of the developed model, this case can be described by the inequality $\tilde{\epsilon} < q^{-1}v_0$. In the opposite case
$\tilde{\epsilon} > q^{-1}v_0$ of larger tendency to form patterns, the moving patterns experience the transition to the resting  state
without changing their density structure. This transition emerges through a monotonic decrease of the pattern velocity that drops to zero at the
transition boundary. Recall that the transition to the homogeneous state, in contrast, occurs at finite collective velocity of the SPPs. The amplitude
of the patterns, quantified through the RMSD defined above, behaves just  opposite to the collective velocities. Specifically,
the amplitude tends to zero at the moving state-homogeneous state boundary, while having finite values at the moving state-resting state
boundary. This interesting feature highlighting different behavior of the collective velocity and amplitudes of the patterns
in the vicinity of the
transitions between different states, calls for a detailed non-linear analysis to reveal possible bifurcations
between these states of the SPP system. Such an analysis will be reported elsewhere.

Q: Constructor is not being called in a singleton Hi I have the following code and as I am stepping through it in the debugger I notice that the constructor does not get invoked and hence mContext variable initiated within it remains null.
As I am stepping through the debugger the getInstance() function will call the constructor RaceTimeDataContract(Context context), however if I try to step into the constructor it does not and instead the debugger steps to the line where TABLE_NAME is being initialized.  The problem is since mContext remains null, then exception is being thrown.
Anyone know what may be causing this behavior?  Code is below:
public class RaceTimeDataContract implements BaseColumns{
   private static RaceTimeDataContract sInstance;
   private static Context mContext;

   private RaceTimeDataContract(Context context) {
      this.mContext = context;   // This is not getting called
   }
   private RaceTimeDataContract(){}

   public static RaceTimeDataContract getInstance(Context context) {
      if (sInstance == null) {
         sInstance = new RaceTimeDataContract(context.getApplicationContext());
      }
      return sInstance;
   }
   // mContext remains null and forces a exception
   private final String TABLE_NAME = mContext.getResources().getString(R.string.table_name);

Appreciate any feedback!

A: When creating new instances, inline field initialisation is performed before the constructor is called. One simple fix in your case is to move the field initialisation into the constructor after the context is set
e.g. (I've reorganised the code a little, and dropped the this on mContext since it is a static member)
public class RaceTimeDataContract implements BaseColumns {
    private static RaceTimeDataContract sInstance;
    private static Context mContext;

    public static RaceTimeDataContract getInstance(Context context) {
        if (sInstance == null) {
            sInstance = new RaceTimeDataContract(context.getApplicationContext());
        }
        return sInstance;
    }

    private final String TABLE_NAME;

    private RaceTimeDataContract(Context context) {
        mContext = context;
        this.TABLE_NAME = mContext.getResources().getString(R.string.table_name);
    }

     // The below is invalid as it doesn't set TABLE_NAME and should probably be removed
    // private RaceTimeDataContract(){}
}

The above isn't very idiomatic and would be better re-arranged to support a singleton better. There are many ways to do this but some general things which would be a benefit are

*

*Storing the context on the instance object, and not statically

*Preventing race conditions on getInstance

*Removing the default constructor

Assuming you don't retrieve the instance often this can easily be accomplished by synchronising on the getInstance call. e.g.
public class RaceTimeDataContract implements BaseColumns {
    private static RaceTimeDataContract sInstance;

    public static synchronized RaceTimeDataContract getInstance(Context context) {
        if (sInstance == null) {
            sInstance = new RaceTimeDataContract(context.getApplicationContext());
        }
        return sInstance;
    }

    private final Context mContext;
    private final String tableName;

    private RaceTimeDataContract(Context context) {
        this.mContext = context;
        tableName = mContext.getResources().getString(R.string.table_name);
    }
}

As a last note it is atypical of a singleton to take a parameter in the getInstance method but always return the same object - you can imagine in this case that if getInstance is called a second time with a different context then we get the original instance which may have an incorrect table name.
If you do need a singleton per context you can store each instance per context in something like a Map<Context, RaceTimeDataContract>, probably using a ConcurrentHashMap, and it would be better to think of it as some kind of reference cache or factory rather than a singletone.
If possible, it is better to just have a zero parameter getInstance method which can retrieve the singleton context statically the first time it is required. This can open your class up to more typical/simpler singleton patterns like enum singletons and static singleton holders.
