North America’s largest outdoor dog festival came back to Toronto last weekend for its fifth year. It ran from the 9th of June to the 10th of June at Toronto’s historical St. Lawrence Market. A Wikinews reporter was there on Sunday to report on some of the events that happened on the last day.

The “Woofstock” dog festival attracted as many as 140,000 people with their dogs. The festival had tons of accessories, sold under tents, to buy for dogs; food, toys, designer clothes, and more. About 400 vendors and exhibitors were there to promote their products, which also gave private dog companies or groups a chance to show their new products. The local SPCA and some animal rescues were under tents answering questions from visitors. While walking, all visitors could see the CN Tower and other very tall buildings.

One of the local TV stations, Citytv, was there. They hosted a live event at the show which was broadcast on TV. People came up on the stage and asked questions regarding their dogs and the host and co-host answered them.

A man, who called himself the “Chalk Master”, drew two pictures on pavement with chalk. He did it for free but donations were welcome. One was a picture of a girl’s head beside a dog’s head, and another with a wolf.

“Hello Humans. I’ve been invited here to provide your eyeball(s), with some pretty colours. I don’t get paid as I work this weekend strictly for tips… so, if you like what you see please make a DONATION. If you don’t like it simply reach into the pocket of the person next to you and give me their money. CHALK MASTER.”

A contest called “Canada’s top dog” had its own tent with a professional photographer taking pictures of dogs behind a white screen; the winning photo is to be published on the cover of “Puppy and dog basics” magazine.

Large “Gourmet” dog bones were also served from a cart and table.

Next year’s festival is expected to be bigger and better with even more attractions.

Sunday, January 30, 2005Ex-British Culture Minister [Chris Smith has lived with the HIV virus for 17 years, he has revealed to the Sunday Times.

The former cabinet minister decided to go public after the former South African President Nelson Mandela announced his son Makgatho Mandela, had died of AIDS.

‘When I first heard about it, I was really worried because there was hardly any treatment,’ he told the newspaper.

Mr Smith was quickly put on a course of anti-retrovirals after he was diagnosed. He said that he had “been with the National Health Service all the time”.

Chris Smith revealed he was gay in 1984. He was sacked from his post (which he held since 1997) in 2001, after controversies over the National Lottery and the construction of the new Wembley Stadium.

He is due to stand down at the next General Election.

Saturday, March 5, 2005Simply massaging low birth weight babies with sunflower seed oil can protect them from potentially fatal infections.

Infections and complications from preterm birth cause more than half of all neonatal deaths, and very low birth weight babies are particularly vulnerable.

Preterm babies have immature skin that lacks a protective film called vernix that has antimicrobial properties.

In some countries, such as India, newborns are routinely massaged with mustard oil.

But mustard oil, says Gary Darmstadt of John Hopkins University in Baltimore, Maryland, can delay recovery of the skin barrier and have a toxic effect on skin.

Seeking an alternative low-cost product, Darmstadt and colleagues experimented with sunflower oil and an ointment called Aquaphor that comprises petrolatum, mineral oil, mineral wax and lanolin.

The researchers tested the treatments on 497 newborns (72 hours old or less) and preterm babies (less than 33 weeks gestation) between 1998 and 2003 in Bangladesh.

They applied the treatments to the entire body besides the scalp and face three times daily for the first 14 days and then twice daily until discharge.

Babies treated with sunflower oil were found 41% less likely to develop infections than controls.

“Evidence is emerging that the skin is much more important as a barrier to infection than previously recognized, particularly in preterm infants whose skin is underdeveloped,” says Darmstadt. “The good news is that treatment is available to strengthen the function of the skin as a barrier in these vulnerable newborns.”

China property giant Evergrande Group wired USD83.5 million in interest owed in an offshore bond from September 23 on Thursday, temporarily averting default, according to a Reuters source and Chinese newspaper Securities Times.

The wire to a Citibank fiduciary account following a 30-day grace period came after assurances by various members of the Chinese government, Reuters reported. At a Beijing forum Wednesday, Chinese Vice Premier Liu He described the risks as controllable, and chairman of the China Securities Regulatory Commission Yi Huiman said that while authorities needed to curb excessive debt more broadly by “improv[ing] the effectiveness of the constraint mechanism on debt financing”, the matter would be dealt with properly.

Once China’s top real estate developer, Evergrande had accumulated approximately USD305 billion in liabilities, two per cent of the Chinese gross national product, after “dwindling resources” cut its value by 80%, according to Reuters. September data revealed Chinese home sales by value fell by nearly 17% year-on-year, according to The Guardian, and fears over its default led to a slowdown in China’s third quarter GDP growth to a year low of 4.9%. Two sale negotiations with rival developers Hopson Development and Yuexiu, valued at USD2.6 billion and USD1.7 billion, respectively, were suspended, reportedly due to a lack of consent by the government of Guangdong province currently overseeing Evergrande’s restructuring.

News of Evergrande’s remittance caused its shares to rise by as much as 7.8% this morning after a two-week pause in trading for the anticipated sale of 50.1% in Evergrande Property Services Group, and offering some reprieve for bondholders, according to Reuters. Portfolio manager at GaoTeng Global Asset Management James Wong, interviewed by The Guardian, called the news “a positive surprise”, adding “[i]f Evergrande pays this time, I don’t see why it won’t pay the next time.” Jun Rong Yeap for IG Asia pte., interviewed by Bloomberg, said the report “overturned” the narrative “that Evergrande will face difficulty in securing cash ahead”.

Further missed payments are due October 29 and November 11 after similar 30-day grace periods; including yesterday’s USD83.5 million, nearly USD280 million is owed to bondholders.

Stocks have been down for many major Chinese developers: Reuters Wednesday reported year-to-date stock prices fell 87.8% for Sinic Holdings, currently in Fitch Ratings’ ‘restricted default’ after failing to make an October 18 bond payment valued, according to The Guardian, at USD246 million; 80.2% for Evergrande itself; 78.3% for E-House, 58.5% for Fantasia Holdings and 54.6% for Kaisa Group, which defaulted in 2015 and had bonds reach record lows.

Estimates of the Chinese real estate market’s size range from 16 to 25% of the Chinese gross domestic product, according to The Guardian. Chinese President Xi Jinping’s aim to transform the country’s economy from one of debt-fuelled “inflated” growth to one of improved “quality and returns” included imposing regulations on developers that limited their capacity to borrow. A Guardian comment piece from economist George Magnus published on October 15 made reference to China’s “ghost cities” and “rampant credit creation” that has given rise to high vacancy rates and the “financialisaton of housing”.

Vinay Deolalikar, a mathematician who works for HP Labs, claims to have proven that P is not equal to NP. The problem is the greatest unsolved problem in theoretical computer science and is one of seven problems in which the Clay Mathematics Institute has offered million dollar prizes to the solutions.

The question of whether P equals NP essentially asks whether there exist problems which take a long time to solve but whose solutions can be checked quickly. More formally, a problem is said to be in P if there is a program for a Turing machine, an ideal theoretical computer with unbounded amounts of memory, such that running instances of the problem through the program will always answer the question in polynomial time — time always bounded by some fixed polynomial power of the length of the input. A problem is said to be in NP, if the problem can be solved in polynomial time when instead of being run on a Turing machine, it is run on a non-deterministic Turing machine, which is like a Turing machine but is able to make copies of itself to try different approaches to the problem simultaneously.

Mathematicians have long believed that P does not equal NP, and the question has many practical implications. Much of modern cryptography, such as the RSA algorithm and the Diffie-Hellman algorithm, rests on certain problems, such as factoring integers, being in NP and not in P. If it turned out that P=NP, these methods would not work but many now difficult problems would likely be easy to solve. If P does not equal NP then many natural, practical problems such as the traveling salesman problem are intrinsically difficult.

In 2000, the Clay Foundation listed the “Clay Millenium Problems,” seven mathematical problems each of which they would offer a million dollars for a correct solution. One of these problems was whether P equaled NP. Another of theseseven, the Poincaré conjecture, was solved in 2002 by Grigori Perelman who first made headlines for solving the problem and then made them again months later for refusing to take the prize money.

On August 7, mathematician Greg Baker noted on his blog that he had seen a draft of a claimed proof by Deolalikar although among experts a draft had apparently been circulating for a few days. Deolalikar’s proof works by connecting certain ideas in computer science and finite model theory to ideas in statistical mechanics. The proof works by showing that if certain problems known to be in NP were also in P then those problems would have impossible statistical properties. Computer scientists and mathematicians have expressed a variety of opinions about Deolalikar’s proof, ranging from guarded optimism to near certainty that the proof is incorrect. Scott Aaronson of the Massachusetts Institute of Technology has expressed his pessimism by stating that he will give $200,000 of his own money to Deolalikar if the proof turns out to be valid. Others have raised specific technical issues with the proof but noted that the proof attempt presented interesting new techniques that might be relevant to computer science whether or not the proof turns out to be correct. Richard Lipton, a professor of computer science at Georgia Tech, has said that “the author certainly shows awareness of the relevant obstacles and command of literature supporting his arguments.” Lipton has listed four central objections to the proof, none of which are necessarily fatal but may require more work to address. On August 11, 2010, Lipton reported that consensus of the reviewers was best summarized by mathematician Terence Tao, who expressed the view that Deolalikar’s paper probably did not give a proof that P!=NP even after major changes, unless substantial new ideas are added.

They are cheap, useful, and very plentiful, and that is exactly the problem, according to researchers. A report issued on Feb. 23 by a cadre of environment and economics researchers suggested that Kenya should ban the common plastic bag that one gets at the checkout counter of grocery stores, and place a levy on other plastic bags, all to combat the country’s environmental problems stemming from the bags’ popularity.
