Improvements are made to two areas of the United Kingdom Chemistry and Aerosol (UKCA) module, which forms part of the Met Office Unified Model (UM) used for weather and climate applications. Firstly, a solar cycle is added to the photolysis scheme. The effect on total column ozone of this addition was found to be around 1–2% in mid-latitude and equatorial regions in phase with the solar cycle. Secondly, reactions occurring on the surfaces of polar stratospheric clouds and sulfate aerosol are updated and extended by modification of the uptake coefficients of five existing reactions and the addition of a further eight reactions involving bromine species. These modifications are shown to reduce the overabundance of modeled total-column ozone in the Arctic during October to February, southern mid-latitudes during August, and the Antarctic during September. Antarctic springtime ozone depletion is shown to be enhanced by 25 DU on average, which now causes the ozone hole to be somewhat too deep compared to observations. We show that this is in part due to a cold bias of the Antarctic polar vortex in the model.

An early sign of spring, earlier than ever Related Unprecedented flowering follows record warmth When botanists began collecting plant samples for herbaria more than a century ago, their goal was to catalog and understand the diversity of the natural world. These days scientists use the collections to understand the transformative effects of climate change.The issue, says Barnabas Daru, is that the collections are a flawed fit for that use.Daru, a postdoctoral fellow in organismic and evolutionary biology working in collaboration with Charles Davis, a professor in the same field and director of the Harvard University Herbaria, is the lead author of a study published in New Phytologist that points to sampling biases in a number of herbarium collections around the world. He suggests that those biases must be taken into consideration by researchers focused on climate change.“These specimens are becoming the gold standard for addressing questions related to climate change, ecology, and niche modeling,” Daru said. “But these data were not initially collected for those purposes, so the goal for our study was to evaluate these biases to facilitate downstream research.”,With their records of flowering times and details on how plants have adapted to climate over more than a century, herbarium collections play a key role in understanding how climate change impacts the natural world and how those effects might be felt by humans. Getting genetic leg up on climate change Botanist Charles Davis urges evolutionary biologists into the fray “Plants are at the beginning of the food chain,” Daru said. “So if there is a disruption in flowering time, it effects everything that depends on that. It may be that 100 years ago bees came to pollinate plants in May, but now that flowering time has shifted to earlier, into April, then there is potentially a mismatch in terms of timing … and everything is affected downstream.”Daru and colleagues selected three digitized collections — the flora of New England, including many collections from the Harvard University Herbaria, and herbaria in Australia and South Africa — and examined them across categories ranging from when and where samples were collected to which species were collected.“We found widespread biases across all five dimensions we examined,” Daru said. “The data show there is a strong tendency for botanists to collect plants close to roadsides rather than deeper in the landscape, and there is also a strong preference for collecting plants in the summer versus the winter or fall.”Some historical collections were the product of just one or two “mega-collectors” who amassed huge troves of plant samples.“There’s sort of a founder effect,” Daru said. “So all the people who are collecting plants today are following in the footsteps of these mega-collectors, and as a result they tend to collect in the same area or in some cases the same groups.”,In the South African and Australian collections, researchers found a tendency for samples to be collected at lower altitudes, while botanists in New England frequently collected at higher altitudes in regions such as the White Mountains.“In the collections we examine, areas around Massachusetts and Connecticut are densely collected, whereas other regions are less represented,” he said. “Similarly, in South Africa, there are dense collections from the Cape region, but areas further inland are less collected, and the same is true for Australia.“It’s possible that these areas may be under-collected because there isn’t much plant diversity there,” Daru said. “But one reason we want to understand that is for future collecting efforts. We might prioritize these areas as places to explore diversity rather than concentrating on other, well-visited regions.”,The study also uncovered evidence of ways in which external events shaped the behavior of collectors.In the years following World War II, for example, collecting activity dropped worldwide. By contrast, after post-war immigration of Europeans to the continent, collecting activity exploded in Australia.In the end, Daru said, the purpose of the paper isn’t to suggest that biases inherent in herbarium collections are a fatal flaw, but rather that they must be considered as part of future studies.“The goal is not to portray [those biases] in a negative light,” he continued. “Without these data we would have no record of the natural history of plants, so these are very unique and important collections. But because they are increasingly being used … we need to make sure we can account for any possible biases that may exist in the data.”This research was supported with funding from the Harvard University Herbaria.
The government of Somaliland asked Notre Dame computer science professor Kevin Bowyer with graduate students Amanda Sgroi and Estefan Ortiz to use their iris recognition biometric research to improve the legitimacy of their elections.Somaliland is a self-declared independent state directly north of Somalia recognized by the international community and U.S. as an autonomous region of Somalia. According to a College of Engineering press release, it is transforming into a rare, multiparty democracy in the Horn of Africa and is working to establish honest, respected elections.“Someone in Somaliland sent me an e-mail asking me to help with improving their voting register,” Bowyer said. “They said they wanted to use iris-recognition technology and asked us for help.”“The ultimate goal is that you can only vote one time,” Sgroi said. “If you’re trying to vote a second time, then the iris recognition system is going to block you before you can even cast your ballot.”Bowyer said they kept in constant e-mail contact with the Somaliland government and were able to produce results that they could use to help achieve the Somaliland government nation status within a short period of time. In the press release, he said the data acquisition for the field study took place over a five-day period in registration centers in Hargeisa, the Somaliland capital, and Baki, a town 60 miles away from Hargeisa. The data was transferred electronically to the Notre Dame team, who sent the results back after conducting iris recognition analysis.“They wanted to take some current technology, go to a couple of towns take some data and seed it with some duplicates,” Bowyer said. “They wanted to give us the data basically, if we could tell them which registration belonged to the same person and which actually belong to different people.”Bowyer said the challenge revealed issues with the flexibility of their current technology despite the already extensive research into iris recognition.“The key things we identified were the challenging images,” Sgroi said. “We had some people with had some medical issues with their eyes and some eyes that were blurry so they were poorly acquired, so having some quality checking is going to be necessary for their final system.”“Since 2004, we’ve been doing iris recognition [research] here — 10 years,” Bowyer said. “We’ve looked at thousands of images of several thousand people, I’m guessing. They sent us the images of around 500 people … and there were at least two things I’ve never seen before … that broke all the segmenters we had.“It drove home that if you’re developing code for the U.S., the U.K. and big cities like in China and then take it to say, Africa, you’re going to run into these eye conditions you’ve never seen before and the software is not going to work — and the software doesn’t know it’s not going to work either. So that’s a new topic of research we could work on.”Bowyer said access to this data could update the U.S.’s dated biometric scanning technology currently in use. Bowyer said the experience also provides domestic insight on the ethics of collecting data from private citizen.“The country of India will have one to two billion people with a national ID to link with their economic identity that’s working from fingerprint and iris, and I think the United States will be behind,” Bowyer said. “We talk about having secure borders and stuff, yet we’re not willing to do stuff about secure ID.”“I think the climate right now, we’re really sensitive about security with the NSA stuff going on,” Sgroi said. “I think that maybe, not in the United States, this similar voter ID thing would be popular and more successful, but it will not happen here. There would be a discussion on whether we want it, but it will take a lot to convince the public to run with it.”Tags: Computer science, Somalia, Somaliland
The Gay and Lesbian Alumni group of Notre Dame and Saint Mary’s (GALA) will host an award ceremony this weekend to honor Kristen Matha, who graduated from Saint Mary’s in 2003, with the Thomas A. Dooley Award.Chair of the Notre Dame and Saint Mary’s chapter of GALA Jack Bergen said this award was named after Tom Dooley, a former Notre Dame student who served in the Navy.“The Dooley award was established to recognize individuals who have been leaders in advancing the human and civil rights of LGBT individuals,” Bergen said. “Our organization chose Dr. Dooley as an inspiration for his courage, passion, commitment and for helping others and his love for Notre Dame. It also happens that he was a gay man who unfortunately had his military career end way too early as a result of his [sexual] orientation.”Matha said she is honored to receive this award, and is also excited for the opportunity this weekend will present to others in the community.“For some folks, this might be their first opportunity to really engage with the LGBTQ community of Saint Mary’s and Notre Dame to this level, so I’m really excited about that and continuing to build community and support around LGBTQ inclusion,” she said. “I’m honored that my work is being recognized by my peers from Saint Mary’s and Notre Dame.”Matha is being recognized for being a leader in advancing LGBT human and civil rights during her time at Saint Mary’s and at the NCAA, where she now works, Bergen said.“At Saint Mary’s, she was able to assist the development of a student leader workshop focused on creating a more welcoming and inclusive campus for LGBTQ students,” he said. “At the NCAA, she has championed causes to improve LGBT benefits for employees, and has facilitated numerous LGBTQ inclusion trainings for NCAA staff, student athletes and administrators. She has made a substantial impact everywhere that she has gone.”Bergen said he hopes this award serves as an inspiration to others in the Notre Dame and Saint Mary’s community.“By highlighting the accomplishments of someone like [Matha] and those award recipients before her, we hope to encourage everyone — including current students — to aspire to the same spirit of strength, leadership and compassion in working for change and improvement for the LGBT community,” he said. In addition to the award ceremony — at which GALA will also announce this year’s recipient of a scholarship awarded annually to an LGBT student from Notre Dame or Saint Mary’s — there will be a networking event Friday night at Legends for alumni and students. There will also be a panel of Saint Mary’s and Notre Dame faculty and students, as well as a legal advisor, called “Reconciling Religious Freedom with Civil Rights” in Carey Auditorium in Hesburgh Library on Saturday at noon, which will explore how universities and colleges create a supportive environment for LGBT students while ensuring the rights of everyone in their communities.Matha said she hopes that people in the Saint Mary’s and Notre Dame community are moved towards solidarity after this weekend.“When I was a student and I was only out to a few trusted friends, I felt very alone on campus,” she said. “I hope this level of visibility gives our students a feeling of solidarity and a feeling of hope that both campuses will continue to work at creating more inclusive environments, not only for LGBTQ students, but for all students that come from underrepresented groups.”Tags: GALA-ND/SMC, LGBT, sexual orientation, Thomas A.

The IDX reported that publicly listed companies’ net profit dipped early this year. In the first quarter, the aggregate net profit declined 27.3 percent year-on-year (yoy) to Rp 72.77 trillion (US$5.01 billion), with only a few sectors booking growth. Adrianus noted that, in the second quarter, most companies’ earnings were below expectations, despite him already expecting a poor performance. Going forward, he recommended that investors take different approaches in the third and fourth quarters.“In the third quarter, we will stick to defensive names, those with resilient earnings profiles and huge dividends that make their valuation quite premium in comparison to the others,” the analyst said. Read also: Domestic investors dominate stock market amid pandemicHe explained that consumer stocks, telecommunication and tower players were preferred for their earnings feasibility, while also adding commodity stocks that trade nickel and gold to his list of preferred stocks. “Going into the fourth quarter, the story is reversed. Those who suffer in the third or second quarter, whose performance was bad, should create a low-base performance for a rebound,” he said. He went on to say that these stocks that suffered during previous quarters would most likely recover significantly when market uncertainties passes, hence, suggesting investors look into property and construction stocks as well as banks that had suffered from loan restructuring in previous quarters.Topics : Investors should gear up for upcoming market uncertainty nearing the United States presidential election, an equity analyst has said, suggesting that August would be the last month for now to go on a buying spree. “August may be the only month we can happily trade [this year]. After that, we suggest investors go defensive to survive the upcoming turmoil,” Sucor Sekuritas head of research Adrianus Bias said in a discussion with The Jakarta Post on Tuesday. Read also: Pharma stocks surge as market brims with vaccine optimism “And then, probably in the fourth quarter – around November, December – we can start to actively trade again after the dust settles,” he said, adding that there would likely be adjustment in the market as investors waited on the election winner’s policy announcement. Adrianus noted that with the forthcoming ambivalence in the market, he projected that the benchmark Jakarta Composite Index (JCI) would not return to the level of 6,000 points or even break above 5,500 points this year.Additionally, the lower-than-expected earnings performance from companies listed on the Indonesian Stock Exchange (IDX) also contributed to the index inability to recover to its prepandemic level this year, he said. The JCI is down 17.68 percent so far this year after closing at 6,299.54 on the last day of 2019. Following the market rout in March, the index recorded an upward rally that sustained until July. Since the beginning of August, the JCI has gained around 1.41 percent.
Tylor A. Adams, age 22 of St. Mary’s, died Tuesday, April 25, 2017. He was born April 12, 1995 in Batesville and worked as roofer for the Roofing Monkeys. Tylor loved to fish and did some hunting too. A Bengals and Reds fan, he enjoyed playing and watching basketball as well and was a big fan of Kobe Bryant. He preferred being outdoors and always teased that he would move to Alaska and live off the land. According to his family, he would have been able to do it. They also said he liked to doodle and was always listening to music, with a preference for country. His two biggest passions were his daughter and being with family.He is survived by his daughter Brookelynn Adams; mother and step father Melissa and Richard Lecher of St. Mary’s; father and step mother Tony and Cheryl Adams of Moores Hill, sisters Amanda (Andy) Schneider and Kayla (Kyle) Hountz, both of Batesville; step sister Betty (Brad) Johannigman of Milhousen; step brothers Ray (Sammi) Lecher and Allen (Hannah Federle) Lecher, both of Batesville; grandparents Sharon and Bob Cooper of Batesville; step grandfather Tom Lecher of St. Mary’s as well as numerous nieces, nephews, aunts, uncles and cousins. He is preceded in death by grandmother Dianna Robinson and step grandmother Barb Lecher.There will be no services. A visitation will be held Saturday, April 29th, from 9 a.m. until Noon at the Weigel Funeral Home. Tylor will be cremated following visitation. The family requests memorials to the Brookelynn Adams Trust Fund.
A month after winning golf’s so-called unofficial ‘fifth major’, Ryder Cup hero Martin Kaymer charged into the lead of one of the real things in the US Open. Sweden’s Henrik Stenson, who can overtake Adam Scott as world number one by claiming his first major title on Sunday, was among a 10-strong group on one under as the early starters in particular made the most of more receptive greens than had been expected. Six-time runner-up Phil Mickelson, looking to become only the sixth player to win all four majors, was another shot back on level par alongside English trio Ian Poulter, Paul Casey and Danny Willett and Welshman Jamie Donaldson. Sheffield amateur Matt Fitzpatrick briefly held a share of the lead after starting with two birdies in his first three holes, the 19-year-old eventually signing for a 71 – one better than playing partner and defending champion Justin Rose. Former champion Rory McIlroy was alongside Fitzpatrick on one over after struggling to get the pace of the greens. McDowell admitted the early starters had enjoyed the luck of the draw, adding: “I spent the last few days just preparing myself mentally for the challenge, knowing that this golf course wasn’t going to give much and it was only going to take. I really felt like I got my head in the right place the last few days. “It wasn’t my best ball-striking display, but you don’t have to strike it amazing around here – you just have to position the ball correctly at all times, and with a tiny bit more moisture this morning we got lucky. “In practice the golf course seemed to be very firm, kind of a weekend set-up. I guess the USGA were really relying on some rain last night, which didn’t come. I’m assuming they put some water on this place this morning and we were able to take advantage of that a little bit early on, and actually think about getting at some of those flags.” Speaking about the Open Championship returning to Portrush in 2019 – it was last staged there in 1951 – McDowell added: “That’s extremely exciting. I’ve been kind of hesitant to comment because I really didn’t want to take anything away from the official announcement (the R&A are holding a press conference in Portrush on Monday). “I’m very proud of where I grew up. I’m very proud of the tradition and history there and to bring an Open Championship back to Northern Ireland is very special. It speaks volumes about how far the country has come. “It’s going to be a very special thing for Northern Ireland and Ireland in general. I just hope I’m exempt and playing well. It’s been a dream of mine as a kid. I’ve spent many an hour out there as a kid and dreaming of playing major championships. To have a major championship come to Portrush, (especially) the Open Championship is special stuff. “It’s the result of a lot of gentle ribbing in the direction of Mr Dawson (R&A chief executive Peter Dawson) the last four or five years from myself and (Rory) McIlroy and (Darren) Clarke. Nice to see the fruits of our labour, I suppose.” And the man who ensured Europe would retain the Ryder Cup after the ‘Miracle at Medinah’ in 2012 reproduced the form he displayed at Sawgrass on Thursday, beating the previous lowest score in a US Open at Pinehurst of 66 by Sweden’s Peter Hedblom in 2005. “When you win the Players it’s pretty much as if you have won a major, the way the field is,” said Kaymer, who equalled the course record with an opening 63 at Sawgrass. “I needed a win, whether it was the Players or a PGA Tour event for my confidence, to feel it’s worth it for all the hard work I have put in over the last couple of years. “That was a nice, huge win and, coming into the US Open and the next few weeks with big events, it’s nice if you’ve just won before. I’m very happy. “I was asked before what score I would take at the end of the week and I said eight over, so hopefully that’s not going to happen now. The course played more difficult on Monday, Tuesday and Wednesday – they must have put more water on the greens last night. “I watched some golf in the morning and thought it was more playable and even in the afternoon we could stop the ball on the greens. It’s an exceptional score and very nice to lead the tournament but I was very surprised the course played fairly soft. “I try to win as many majors in my career as possible. I won one so far, I put myself so far in a good position here, but we have three rounds to go. There’s so much golf to play and no-one should expected me to shoot another 65.” McDowell had earlier celebrated confirmation of the Open’s return to his home course of Portrush by firing an eagle, one birdie and one bogey to shoot 68 – his lowest opening round in a US Open. Kaymer carded six birdies and one bogey to record a superb five-under-par 65 at Pinehurst, claiming a three-shot lead over former champion Graeme McDowell, Zimbabwe’s Brendon de Jonge and American duo Kevin Na and Fran Quinn. The 29-year-old German, who won the US PGA in August 2010 and became world number one for eight weeks the following February, became just the fourth European to win the Players Championship in 41 years last month.

A fourth person has been indicted in the 2017 murder of a local MMA fighter.Aaron Rajman, reportedly known as the only local Orthodox Jewish MMA fighter, was shot and killed during a home invasion in July of 2013.On Thursday, a grand jury indicted Cameron Burgess-Clark on charges of first-degree murder and armed home invasion.He was booked into the Palm Beach County Jail and is being held without bond following a hearing Wednesday morning.It is unclear at this time what role the 25-year-old Riviera Beach man is alleged to have played in the fatal shooting of Rajman.In August of 2017, three suspects, including a 16-year-old old girl, were indicted on charges of first-degree murder and armed home invasion in connection to Rajman’s death.The suspects, Summer Church, Jace Swinton, and Roberto Ortizstole, reportedly broke into Rajman’s Boca Raton home and stole multiple items, including swords, marijuana, a scale, narcotics, and money.Rajman was fatally shot while the robbery was in progress after engaging in a physical confrontation with several men who entered his home around 10:30 p.m, according to PBSO.In July of this year, Church, who was 16 at the time of the killing, and Swinton, who was 18, plead guilty to second-degree murder and were sentenced to 10 years in prison and another ten years of probation.A trial has not yet been set for the case against Ortiz, who was 18 at the time of Rajman’s death.
BARBADOS Pride secured a one-wicket win in a low-scoring Group B clash against Jamaica at the Kensington Oval, to keep their unbeaten streak intact in the Regional Super50 competition so far.After Jamaica Scorpions were bowled out for 190, Pride lost half their side for 83, before recovering through late contributions and eventually limping past the finish line with two overs to spare.They rode on a vital 40 from Shane Dowrich who came out with the score on 62 for 4; by the time he fell, caught behind in the 38th over, Barbados were eight down and still needed 48. The ninth-wicket partnership between Ashley Nurse and Kemar Roach knocked off 42 of those runs, with Nurse calmly seeing the side to the win and finishing on 21 not out.Jamaica’s new-ball duo of Jerome Taylor and Reynard Leveridge took five wickets between them, while Nikita Miller impressed with 1 for 22 in 10 overs.When Scorpions batted, after winning the toss, they were in an early wobble at 27 for 3. Jermaine Blackwood held up his end for 40, but his wicket left the side at 97 for 6.They recovered through a seventh-wicket partnership of 77 between Rovman Powell who top-scored with 74 and Damion Jacobs who struck 31. Powell’s knock, which came at a strike rate of 93.67, included three fours and six sixes.He was the eighth man to be dismissed, seven balls before Scorpions were all out. Barbados Pride new-ball duo did the bulk of the damage with Roach and Jason Holder snaring three wickets each.JAMAICA SCORPIONSJ. Campbell c Alleyne b J Holder 0C. Walton c Benn b Roach 6J.
