It is shown how to reconstruct the stacking sequence from the pairwise correlation functions between layers in close-packed structures. First, of theoretical interest, the analytical formulation and solution of the problem are presented when the exact pairwise correlation counts are known. In the second part, the practical problem is approached. A simulated annealing procedure is developed to solve the problem using as initial guess approximate solutions from previous treatments. The robustness of the procedure is tested with synthetic data, followed by an experimental example. The developed approach performs robustly over different synthetic and experimental data, comparing favorably with the reported methods.

The monoclinic crystal structure of Na2SO3(H2O)7 is characterized by an alternating stacking of (100) cationic sodium–water layers and anionic sulfite layers along [100]. The cationic layers are made up from two types of [Na(H2O)6] octa­hedra that form linear 1∞[Na(H2O)4/2(H2O)2/1] chains linked by dimeric [Na(H2O)2/2(H2O)4/1]2 units on both sides of the chains. The isolated trigonal–pyramidal sulfite anions are connected to the cationic layers through an intricate network of O—H⋯O hydrogen bonds, together with a remarkable O—H⋯S hydrogen bond, with an O⋯S donor–acceptor distance of 3.2582 (6) Å, which is about 0.05 Å shorter than the average for O—H⋯S hydrogen bonds in thio­salt hydrates and organic sulfur com­pounds of the type Y—S—Z (Y/Z = C, N, O or S). Structural relationships between monoclinic Na2SO3(H2O)7 and ortho­rhom­bic Na2CO3(H2O)7 are discussed in detail.

With the coronavirus forcing much of Europe to tone down public celebrations this week marking the 75th anniversary of the end of World War II, the small nation of Belarus is raising eyebrows — and concerns — by going ahead with a mass military parade in the capital Minsk on Saturday.

The move reflects the business-as-usual approach of the country's longtime president, Alexander Lukashenko — a former Soviet collective farm director leading what the U.S. once dubbed the last dictatorship in Europe.

As the coronavirus has raced across the globe, Lukashenko has dismissed the pandemic as mass "psychosis" — a disease easily cured with a bit of vodka, a hot sauna or time spent playing hockey or doing farm work on one of country's legendary Soviet-designed tractors.

The country's soccer league still competes. Belarus' schools opened after a short delay. And annual Victory Day celebrations will go on.

The government "simply cannot cancel the parade," the Belarusian leader said in a Cabinet meeting this week. "It's an emotional, deeply ideological event."

In a rare concession to at least some social distancing measures, Lukashenko has urged Belarusian men to spend time with their families, rather than their mistresses. But behind the theatrics sits a wily politician who plays to his base in the country's towns and villages, analysts say.

"Lukashenko prioritizes combating panic rather than combating the pandemic," Artyom Shraibman, a Minsk-based political analyst with Sense Analytics, tells NPR. "He downplays the threat, and of course he's very concerned about [the] state of [the] economy."

Shraibman notes similar echoes coming out of the Trump White House.

Belarus has reported over 21,000 suspected coronavirus cases and more than 120 deaths — comparatively low in the global count, but one of the fastest-growing infection rates in Europe, the World Health Organization says.

Amid the growing crisis, Belarusian civil society is rallying to fix what Lukashenko will not. With many Belarusians now self-isolating by choice, even the country's health ministry has endorsed some public distancing measures over Lukashenko's advice.

Volunteers have raised money to buy personal protective gear for hospitals. Restaurants have donated food. Hotels provide rooms pro bono to medical workers. Private businesses have raised funds.

"People who normally don't talk to each other are working together to help," says Andrej Stryzhak of #ByCovid19, a group of volunteer activists leading crowdfunded efforts to equip health workers across the country. "It's been magical and I don't use that word lightly."

Stryzhak says many are bracing for the aftershocks of Saturday's Victory parade, where attendance isn't required but there are reports of pay bonuses given to those who show up.

"We believe in statistics. And the experts and doctors tell us that if there's a crowd, then expect a new spike in cases a week or two later," says Stryzhak. "Belarus isn't Mars," he adds, noting that the country is as susceptible to the virus as any other.

Meanwhile, Lukashenko's contrarian approach has also fueled a rift with Belarus' big brother to the east. Russia has embraced lockdowns amid its own soaring coronavirus infection rates.

This week, the Belarusian leader ordered the expulsion of a journalist from Russia's Channel 1 state television network after it aired a report criticizing Lukashenko for risking lives and ignoring the pandemic.

"Leave us alone and don't count your chickens before they hatch," said Lukashenko. "Later we'll sit and find out who was right."

For freelancers, consultants, actors and other self employed people, life gets complicated this time of year. Digging around for the paperwork to fill out tax forms practically qualifies as exercise.

"They have a nightmare trying to find receipts," said accountant Tristan Zier.

Zier founded Zen99 to help freelancers manage their finances, including filing their taxes.  His most important advice to freelancers: keep track expenses and receipts year round rather than pursuing a paper chase as April 15 nears.  

"When they can’t find receipts, they can’t write off their expenses," he said. "And they’re paying more money to the government instead of keeping it for themselves."

Zier and others have come up with a lists of common mistakes freelancers make at tax time. 

Here are seven don't - or, deadly sins, for freelances at tax time:

1. Not knowing what they owe.  Zier says there are 20 different 1099 forms that get sent out to workers to track freelance gigs.  One of them is the 1099-K, which only has to be sent to you by a company in paper form if you make over $20,000. "People think, 'Great, no paper form, no taxes on that," says Zier. "Big mistake there.  You still have to self-report the income."   
2. Not knowing WHEN they owe.  For freelancers who owe more than $1,000 in taxes for a year, tax time comes more often than just April 15.  They have to pay taxes quarterly. But then it's not coming out of paychecks like it does for permanent employees. 

3.  Not tracking and writing off the right types of business expenses. Zier says many freelancers fail to realize they can write off part of their cell phone bill as a business expense.  Expenses vary by the type of work.  "A rideshare driver's biggest expense will be related to their car, while a web developer's biggest expense might be their home office," Zier says. "Figuring out what expenses are important to your type of work is important is maximizing your tax savings."

4. Writing off personal expenses.  This goes back to that cell phone.  If you use the same phone for personal and business purposes, don't be tempted to write the whole bill off. Estimate the amount you use it for your work. The same goes for your vehicle. Don't go trying to write off miles driven to the beach. 

5. The Double No-No: counting expenses twice.  Speaking of vehicles, Zier says most people use the Standard Mileage Rate ($0.56/mile for 2014), which factors in gas, repairs and maintenance and other costs like insurance and depreciation. But if you use this rate, you can't also expense your gas receipts and repair bills.  

6. Employee AND employer.  At lifeofthefreelancer.com, financial consultant Brendon Reimer reminds freelancers they play both roles. For regular employees, Federal, State, and payroll taxes are withheld from a paycheck, and distributed on the employee’s behalf. It's how Social Security and Medicare are funded. The IRS mandates that the employer must pay half of every employee’s payroll tax, and the employee is responsible for the other half.  Independent contractors have to handle both halves.  "The IRS does give you a small benefit by letting you deduct the half that you pay yourself as a business expense," Reimer writes. Zier said the freelancer's sin here is believing he or she pays more taxes than the regular working stiff.  

7. Not keeping adequate records. The IRS requires you to keep proof of all business receipts, mileage, etc.  If you can't show these, the IRS  could refute the expense and force you to pay back taxes. Zier says the good news is there are other ways to prove expenses if you've lost the receipt. A bank or credit card statement with the date and location might do the trick. "The IRS is surprisingly accommodating if you are doing your best," Zier says. "If you're being a headache, they're going to be a headache as well." 

In separate reports, Zen99 and the consumer finance web site nerdwallet ranked Los Angeles the best city for freelancers.

Each considered housing and health care costs, the percentage of freelancers in an area as factors. Zier said even before the sharing economy began to take off, the entertainment industry and growing tech scene were already strong sources of freelance gigs in L.A.

"Even back in 2012, L.A. had twelve percent of people report themselves as self-employed on the Census," Ziers said.   "You know your Ubers and companies like that  are really bringing a lot of attention to the contractor market, but it was a very robust community before."

Researchers in Berlin have demonstrated that urban wasteland areas can be used as suitable habitats for a range of grassland species. Using simple and cost-effective measures to sow grassland seed mixtures, they found that such areas flourished despite poor soil conditions and high levels of impact from people.

A new study has investigated the effects of interbreeding a genetically modified squash crop with its wild relative. The findings demonstrate that it could cause wild or weedy relatives to become more resistant to disease.

New research has reviewed the Irish implementation of the first phase of the EU Noise Directive. So far 31 different organisations have been involved and this will increase throughout the second phase of the Directive's implementation. More standardisation is needed to harmonise activities, perhaps by establishing a national expert steering group.

The thinning of Iceland’s ice caps could be influencing volcanic activity, according to new research. The study developed a model to predict the changes in pressure on magma caused by thinning ice and applied it to the recent activity of two Icelandic volcanoes. The results suggest that the effects of thinning ice may increase volcanic activity in some cases, but reduce it in others.

The carbon footprint of food waste should be taken into account alongside the the weight of food wasted, says a new study. The research examined three years of food waste data from six branches of a Swedish supermarket and calculated the waste’s carbon footprint. On the basis of their footprint, key products that could be targeted for waste reduction include beef mince, meatballs and cream, the results suggest.

For older adults, having more or closer family members in one's social network decreases his or her likelihood of death, but having a larger or closer group of friends does not, finds a new study that will be presented at the 111th Annual Meeting of the American Sociological Association (ASA).

Managing relationships is as important for a CIO as having operational and technical competence.

For a CIO-CMO association to deliver true business value there must be a true level of trust and respect built between these two leaders and their teams.

Renewable energy plays an important role in economic development, according to a recent study which investigated the relationship between economic growth and energy consumption in Europe.

The concepts of instrumental value (protecting nature for humans’ sake) and intrinsic value (protecting nature for nature’s sake) are fundamental to environmental policy. This paper — based on a literature review and critical analysis — argues that using these concepts alone overlooks important concerns for the environment. The authors recommend also considering relational values, which derive from the relationships between people and nature.

Ireland’s Environmental Protection Agency (EPA) established the Network for Ireland’s Environmental Compliance and Enforcement (NIECE) over 10 years ago to ensure an effective, integrated, national approach to the enforcement of environmental legislation, as presented in a recent conference paper and a report from the EPA.

Energy production uses large quantities of water and, in turn, water provision requires considerable amounts of energy. A new study has investigated the interconnection between water and energy, the ‘water-energy nexus’, in Spain and found that 5.8% of total electricity consumption is for water-use and 25% of water withdrawals are for energy generation.

Ireland's national agri-environment scheme can reduce nitrate leaching from beef farming, shows a recent study. Nitrate leached at an average rate of 17.3 kilograms per hectare (kg/ha) on studied plots which complied with the scheme. This compares with 63.1 kg/ha on intensively farmed plots. The programme can therefore help Ireland meet requirements of the EU’s Water Framework Directive (WFD) and Nitrates Directive, the researchers suggest.

Plastic pollution in the ocean is a growing problem. This study, which is the first to investigate the presence of plastic debris in large pelagic fish in the central Mediterranean Sea, found that over 18% of fish had ingested plastics.

Facebook said that when people saw those warning labels, 95% of the time they did not go on to view the original content. To date, the social media giant also removed hundreds of thousands of pieces of misinformation that could lead to imminent physical harm.

The tax also applies to advertising revenue earned from companies overseas if those advertisements eventually target customers in India. Google is particularly concerned that it would not be able to swiftly identify countries where such advertising arrangements were in place, Reuters has reported.

The cloud giants have seen a drop-off in new contracts from big clients for server storage and to overhaul tech.

Wild plants closely related to crops, or ‘crop wild relatives’, contain genes that could be useful for developing resilient crop varieties and are, therefore, important for food security. This global study quantified their conservation status and availability for breeding. The researchers found major gaps in gene-bank stocks, with over 70% of crop wild relative species identified as ‘high priority’ for conservation action. The researchers say systematic efforts are needed to protect crop wild relatives for future plant breeding, including both protection in gene banks and local conservation.

Nitrogen and phosphorus pollution change the relationship between the tropical coral Stylophora pistillata and the algae living inside its tissues, a recent study has found. The researchers say the pollutants, mainly from urban and agricultural discharges, affect algae photosynthesis and the essential transfer of carbon from algae to the coral.

Maps of the risk of griffon vultures’ exposure to lead in north-eastern Spain have been produced in a new study. High-risk places are mountainous areas where there are high levels of bioavailable sources of lead in the soil, but also where game hunting is prevalent, and carcasses scavenged by the birds may contain lead ammunition.

A new study has analysed the environmental impact of 15 products containing nanosilver, highlighting the contribution of this novel material to the items’ overall environmental burden. The findings show that nanosilver impacts, such as fossil fuel depletion and human-health impacts, are relative to content, and can be marginal when considered in the context of the product’s other materials. Based on their results, the researchers recommend considering the overall impacts and benefits of nano-enabled products in evaluation and environmental guidance on their development.

Increased black smoke pollution was associated with increased mortality rates almost a month after exposure in a recent study. The researchers studied death rates in relation to pollution concentrations over a 22-year period in the city of Glasgow, UK, and found significantly higher mortality rates among residents at 13-18 and 19-24 days after increased exposure to black smoke.

SALEM – As part of the ongoing construction to replace the bridge over Back Creek on Route 220, an extended lane closure has been scheduled for next week. The bridge is near the intersection of Route 657 (Crowell Gap Road and Winter Drive).  Beginning Monday, October 8 at 9 a.m., the right northbound lane of Route 220 and the crossover at Crowell Gap Road will be closed until Wednesday, October 10 at 5 p.m. to pave a segment of the roadway that will connect to the new bridge. Drivers traveling on Route 220 northbound into Roanoke should expect significant delays on Route 220 during this time and are encouraged to plan their travel accordingly. The bridge replacement is expected to be complete in spring 2020. For updates on this project and other traffic impacts and lane closure, visit www.511Virginia.org .
