Twelve Longhurst Hardy Plankton Recorder (LHPR) profiles were taken over a 16 h period in January 1990, in order to study feeding of four copepod species at an Antarctic oceanic site near South Georgia. Vertical distributions of their life stages, as well as those of dominant competitors and predators, are described in relation to the feeding cycles of Calanoides acutus CV, Calanus simillimus CV, Calanus propinquus CV and Rhincalanus gigas CIII, CV and CVI♀. Comparisons with vertical ring-net catches, which were used for concomitant gutevacuation experiments, demonstrated the suitability of the LHPR for these fine-scale studies. Planktonic predators, with the exception of the diel migrant Themisto gaudichaudii, resided deeper than the herbivores. During the day and around midnight, when feeding rates were low, species and stages reached their maximum vertical separation. At these times, new generation copepodites of the four species lived progressively deeper and the overwintered generation (i.e., R. gigas Stages CIV, CV, CVI) were progressively shallower. During the afternoon or evening (depending on species), all stages older than CII, as well as Euphausia frigida and T. gaudichaudii, migrated upwards, to amass in the surface mixed layer. Feeding was restricted to darkness, although R. gigas commenced several hours before dusk. In detail their migration and feeding differed widely, with combinations of unimodal and apparent bimodal cycles. As a whole, the results suggest that (1) feeding could occur during sinking as well as during upward migrations, (2) upward migrations were not always associated with feeding increases, and (3) individuals appeared to descend after filling their guts.
October 21, 2019 /Sports News – Local Weber State Football’s Josh Davis Named Big Sky Player of the Week Tags: Josh Davis/NCAA football/Northern Arizona/Weber State Football Brad James Written by FacebookTwitterLinkedInEmailOGDEN, Utah-Monday, Weber State sophomore tailback Josh Davis was named as the Big Sky Conference offensive player of the week and the FCS National Offensive Player of the week by College Sports Madness.Davis set a school record with 328 rushing yards in the Wildcats’ 51-28 rout of Northern Arizona Saturday at Stewart Stadium.Davis’ 328 yards are also the most rushing yards in game in all of NCAA football this season. This entails NCAA Division I (FBS and FCS), Division II and Division III.Davis currently has 91 carries for 620 yards on the season and seven rushing scores.He has 1,982 career rushing yards for the Wildcats, which is 11th in school history.
This is not a political issue. It’s about credibility. The mayor has displayed a lack of transparency throughout his term – from a closed-door homestead tax meeting, playing a shell game with our finances, withholding hotel details, and now withholding from the public knowledge about a city council election. This election needs to be about the truth.I called this press conference to assure you as Mayor that I will be open, honest and transparent. Action must be taken in order to prevent future abuses. I have been a long time advocate of children and their right to a happy, healthy childhood. I recently received the “2015 Friend of Children” award from the Indiana Association of Resources and Child Advocacy and I serve on the Commission for the Improvement of the Status of Children. I spoke to Superintendent Glenda Ritz earlier today, to ensure training is available for the Evansville Vanderburgh School Corporation. The training is called “Adults Protecting Children.” I will re-establish the Education Round Table to ensure that our children come before our politics. We have great schools and great teachers but the Mayors office always has responsibility to protect our children. As Mayor I will continue to advocate for the safety of our children.Gail Riecken is running for Mayor of Evansville and is a former Evansville City Council-woman, Evansville Parks Director, and a current member of the Indiana State House of Representatives. She is a lifelong Evansville resident, has been married for 47 years, and has 2 children and 3 grandchildren. I have been asked to make a statement regarding Mayor Winnecke’s handling of Mr. Schriber’s recent admission to sexual misconduct with a 15 year old male student. I first will comment on the Mayor’s handling of this situation, and then talk about how we move forward to protect children in the future. While the timing of the leak to the press brings out the worst in politics, it also brings to light my concerns that the Mayor has not been transparent or truthful with the people of Evansville.The Mayor said he was notified of the investigation as early as July. If it were left to the Mayor, the acknowledged molestation involving Mr. Schriber and the student would have never surfaced and Mr. Schriber could have been a city councilman. The Mayor was informed of the allegations before this past Sunday and Mayor Winnecke did nothing. Only when the story broke in the media did Lloyd Winnecke choose to say anything.More questions should be asked of the mayor. His calculated answers that tip toe around the issue should not be allowed to stand.• While the Mayor acknowledges that he was informed about the investigation, does the Mayor expect us to believe that he was not informed about Mr. Schriber’s admission?o Even Tim Ethridge in the Courier and Press (October 24) stated: “It’s difficult to fathom that police officials who are the mayor’s direct reports did not give him all the information, considering all the intertwined relationships.”o During his 2011 campaign the mayor wrote in his position paper on Public Safety, the Police chief will report directly to the Mayor’s office, creating an open, unfiltered flow of information. This direct communication will include frequent briefings…• Winnecke said he remained silent to let the police do their job, but nothing was done in the investigation after August 7th and Mayor Winnecke remained silent. Mayor Winnecke remained silent until the Courier and Press broke the story after voting had already begun. Why didn’t the mayor publicly or privately ask Mr. Schriber to suspend his campaign when he learned of his misconduct?The mayor owes us an explanation as to why he and his campaign continued to have a relationship with Schriber after the Mayor acknowledges he had been informed of the investigation.After Schriber confessed to the sexual misconduct with a student, there was continued support and collaboration between him and the Mayor’s campaign until the Courier and Press broke this story on October 20th.

Dear Tri-State Hockey fans and Evansville IceMen Supporters:I love hockey, and the Evansville community has showed it does too. Your passion, support, and loyalty for the IceMen continue to amaze me.Yesterday, it was announced the IceMen and the City of Evansville are at an impasse, or deadlock, on lease negotiations. As I have told you before, the team operates at a financial deficit because of our current lease. In 2011, we were told at the last minute the deal changed and those lease terms were the only terms we would receive. I had already moved 22 families to Evansville and did not want to cause them hardship so we signed it.The reality is the City’s final position on the financial negotiations of a new lease for the IceMen creates a scenario worse than the current lease. Yes, the City lowered rent. But the flip side is the City wants us to provide it the entire premium seats for free, and wants to take away valuable rights we have in the current lease. The net effect is the City’s proposal will cost the IceMen more than the current lease. We have told everyone since early last year we need a better lease – not worse. Our budgetary needs have changed drastically in the past few years, as like any business our expenses have increased. We are trying to find a way to balance those needs without overtaxing the City, but in the end we are just looking for revenue that we feel is rightly ours, which is ticket revenue and the marketing we sell.I understand the City has to do what is necessary to inject money into its budget and do what it believes is right for the voters. However, I have to do what is right for the IceMen. If I agreed to the City’s terms it would jeopardize the entire IceMen organization. I do not want to do that to our employees, players, coaches, and fans.We generate millions in revenue for the City, local businesses, and vendors that support the team. Our team and our games create hundreds of jobs for the community. We support good causes and nonprofits. We are a proud business citizen of Evansville. For those reasons and others, we have the support of our affiliates, the NHL Ottawa Senators and AHL Binghamton Senators. We also have the ECHL’s support.The IceMen staff and management team are hard at work looking at options for the 2016-2017 season. We will keep you updated with developments as much as possible. In the meantime – get to a game and enjoy the positive family friendly experience of the IceMen games. The bottom line is we need your support. We have garnered a great relationship with the Ottawa Senators and would like to expand upon that relationship in years to come.I remain proud of our staff, I am elated with our fans and I look forward to the playoffs later this season. Go IceMen!Sincerely,Ron Geary, IceMen OwnerFacebookTwitterCopy LinkEmail

Bell Auditorium in Augusta, GA. Fans were in for a treat with the Marcus King Band on deck as opening support, which featured the debut of a brand new song and sit-ins from Derek Trucks and Kebbi Williams during a cover of Derek Trucks Band‘s “Every Good Boy”.During the headlining set, the collaborations continued with Marcus King taking over guitar and vocal duties for a cover of Bob Dylan‘s “Don’t Think Twice” in the encore slot, trading lead vocals with Susan Tedeschi while Derek took a moment off the stage. Additional members of the Marcus King Band arrived on stage for the show-closer, including Dean Mitchell on saxophone, Justin Johnson on trumpet, Stephen Campbell on bass, and Deshawn “D’Vibes” Alexander on keys. With everyone packed onto the stage, the two bands tore through a cover of Joe Tex‘s “Show Me”. The collaboration recalled the many times the members of the two bands performed together during many of the shows on TTB’s “Wheels of Soul Summer Tour” in 2018. Like any great performance, however, Friday’s sit-in featured a unique musical journey of its own, one which everyone in the audience was surely thrilled to be a part of.Check out a snippet of the encore below, courtesy of Instagram user tracithaler123:
Addictive drugs are like a cool spring in the desert or a juicy apple in famine, using pathways in our brains designed to provide life-saving learning about basic needs such as food, safety, and sex, Harvard Provost Steven Hyman said Tuesday evening (Dec. 7) in a talk at the Harvard Allston Education Portal.Hyman, the latest speaker in a lecture series designed to open Harvard’s academic workings to neighbors in nearby communities, conjured up early humanity in explaining what makes addictive drugs so irresistible. These drugs hook us by mimicking brain chemicals such as dopamine that evolved to keep us alive in an uncertain and primitive world, where a key memory like the location of a productive hunting ground or a water source could mean the difference between life and death.The brain was designed to cement such memories and lift them from recollections of humdrum daily activities by creating a pleasurable association, through the release of neurotransmitters such as dopamine. The hook with addictive drugs, however, is that they not only mimic these chemicals, but multiply their effects, causing cravings that push us to seek more and increasing the danger of relapse for those who’ve quit.“Drugs that mimic dopamine’s effects give a powerful false reward signal,” Hyman said.Similar processes are also at work with negative memories, where chemical cascades in the brain signal danger.Hyman, a professor of neurobiology as well as provost, spoke to a crowd of about 60, some of whom peppered him with questions after the talk. The Harvard Allston Education Portal opened in 2008 as a resource to the community. Several programs are run through the portal, including mentoring and community lectures.Bruce Houghton, a member of the Harvard Allston Task Force, said he thought that community presentations such as Hyman’s were “absolutely terrific.” Harvard has always been an excellent educational institution but hasn’t always given neighbors access to that excellence, Houghton said. These programs remedy that.“This is fantastic,” he said.Deb Pasternak of Westborough, Mass., praised Hyman’s ability to work several themes into a coherent whole.“I thought it was wonderful. He has quite the ability to say many things and weave them into one thread,” Pasternak said.Hyman, who led the National Institute of Mental Health from 1996 to 2001, mixed down-to-earth examples (the pleasurable smell of baking bread), with practical cases (a physician addicted to tobacco even though he knows better), with more technical descriptions of how brain chemicals work to highlight why addiction is so difficult for those caught in its web. Once hooked, taking drugs or alcohol becomes an automatic behavior, Hyman said, triggered by certain cues, such as stress, smell, or even seeing a bar.“We need better treatment; this really destroys lives,” Hyman said. “Not everyone who tries these drugs gets addicted, but you don’t know who you are ahead of time.”
In the decades since they were first theorized, scientists have suggested that the exotic properties of topological materials — that is, materials that maintain their electrical properties even in the face of radical temperature shifts or structural deformation — could result in everything from more energy-efficient electronics to the development of novel superconductors and quantum computers.The problem, however, is that identifying the materials with those properties is frustratingly difficult.To speed up the process, Professor of Physics Ashvin Vishwanath and his colleagues conducted a series of studies to develop methods for efficiently identifying new materials that display topological properties.The first two, published in Nature Communications and Science Advances, and co-authored with MIT Fellow Hoi Chun “Adrian” Po, Ph.D. ’18, and Professor Haruki Watanabe of Tokyo University, lay the groundwork for bridging the relevant abstract mathematical concepts with the pragmatic problem of materials discovery. The second, published in Nature this February and co-authored with Po and Feng Tang and Xingang Wan, from Nanjing University, demonstrates the power of the approach and predicts thousands of topological materials candidates.“In the early days, a lot of effort was focused on being able to predict whether a material would be an insulator or metallic,” Vishwanath said. “About 10 or 20 years ago, though, people realized we could produce these topological materials.”Topological materials defy this simple dichotomy. For example, they may have an electrically insulating interior, which is wrapped in a thin skin of metal. The presence of this metallic coating is protected by topology, a mathematical concept concerned with properties that are robust against small physical changes of the system. In other words, if you try to peel off the metallic skin of a topological insulator, the layer underneath will suddenly become metallic.“Insight into the mathematics of these exotic materials would help us find real materials with these topological properties,” Po said. “Right now, the way people do this is really more of a guess … what we wanted to do is to come up with efficient ways of diagnosing whether the materials you’re interested in have a good chance of having topological properties.”The insight required provides a good understanding of how the behavior of the electrons is intertwined with the symmetries of a material’s crystal structure, which can be viewed as an almost infinite array of atoms assembled into delicate patterns. These patterns often remain unchanged if you tilt your head by 90 degrees, or reflect them in a mirror. In physics this property is known as symmetry. In the first two papers, Vishwanath and his collaborators performed a systematic study on this intriguing intertwinement between electrons and symmetries.“The first problem is the huge number of ways in which atoms can form crystals,” he said. “Even if you forget about the chemical complexity, forget about which elements are in there, just in the structure … just from symmetry considerations, there are 230 ways in which you can put atoms together into crystals.”And the complexity doesn’t end there. When magnetism is incorporated the number increases dramatically, from 230 to 1,651.One solution to the problem, Watanabe said, would be to simply test every possible combination to arrive at an eventual solution, but that doesn’t offer any insight into what creates the topological states researchers are after.“We took a different approach,” he said. “The key idea was … we found an efficient way to reformulate the problem such that the symmetry properties of electrons are mapped to coordinates in some high-dimensional space.”These coordinates are like addresses, and the team was able to tell if a material was insulating, metallic, or topological based on its symmetry indicator— the analog of a postal code.Importantly, this “postal code” can be readily characterized. “While the analysis of each magnetic space group would previously have taken a graduate student a day to figure out,” Po said, “our new formulation allows for a simple automation of the task, which is completed on a laptop for all 1,651 instances in half a day.”The new Nature study builds on the ideas outlined in the earlier works, applying them to analyze existing material databases for the discovery of topological materials candidates. Working with collaborators in China, Vishwanath said, the team was able to quickly diagnose the topological properties of tens of thousands of materials using symmetry indicators.“In a way, it’s stage two,” he said of the Nature study. “It proves the utility of the symmetry indicators.”“It’s not a complete free lunch,” he said. “It’s not that you look at the crystal and analyze in detail what the electrons are doing. Rather, we’re only looking at a very small aspect of a complicated system, so it’s a bit like Sherlock Holmes — from a very few clues we can actually infer a lot about the characteristics of a system.”The hope, Vishwanath said, is that these studies will pave the way for developing a “library” of topological materials that can then be further characterized and potentially used for a wide variety of applications.“There are some materials which are predicted to have topological properties, but for which we don’t have an example,” he said. “In other cases, we may only have one kind of topological state … but we may want to have others, not just the one example people have found before.”The research in the Science Advances paper was supported with funding from the National Science Foundation, a Simons Investigator award, and the Japan Society for the Promotion of Science. The Nature paper was supported with funding from the National Key R&D Program of China, the National Natural Science Foundation of China, the Excellent Programme at Nanjing University, Program B for Outstanding Ph.D. Candidates of Nanjing University, a QuantEmX award funded by the Gordon and Betty Moore Foundation’s Emergent Phenomena in Quantum Systems Initiative, the Institute for Complex Adaptive Matter, the National Science Foundation, a Simons Investigator Grant, and a Pappalardo Fellowship at MIT.

Caitlyn Jordan Saint Mary’s Career Crossings Office (CCO) hosted a discussion Wednesday evening titled, “Making a Difference in the World: Pursuing Post-Grad Service and Fellowships,” which featured two alumnae who graduated in 2011.Rachael Chesley, ’11, was accepted as a fellow and scholar in the prestigious Fulbright Program with the U.S. Department of State shortly after graduating. Chesley is currently the Employee Communications Manager with Arthur J. Gallagher & Co. in Chicago. The second alumna on the panel, Caroline Arness, ’11, was accepted to Teach for America (TFA). After serving as a fellow for three years, Arness is now working in a position with TFA as a recruitment associate based in Chicago.Each alumna discussed their respective programs and how they learned to cope with their responsibilities and expectations.Chesley said she was looking for an unconventional path to take after graduating from Saint Mary’s.“Coming out of college is the perfect time for thinking outside of the box,” Chesley said. “You only acquire more responsibilities as time goes on.”Chesley said her experience in the Fulbright Program brought her to Malaysia where she worked as an English teaching assistant.“I was always interested in an international experience,” she said.” “… It provided interesting challenges and opportunities.”In Malaysia, she put in 25 hours per week working with students in her local community. Chesley said she had to learn to quickly adapt to the culture.“I was placed in a rural Muslim community, which as a woman, I had to adapt and sacrifice parts of my own culture,” she said.Teaching posed challenges, as the students did not know how to say phrases as simple as ‘good morning’ in English, Chesley said. In response, she invested her time in the responsibility.“People want to think that the experience you’re having is very romanticized, and it’s not,” she said. “It is a very selfless action depending on the program, and it is important to have people to support you and to remind you why you are doing the experience.”Chesley said she needed to develop her capacity for patience in order to see the results in her students that she desired. It took several months to grow relationships with the students.“It was not until I was able to get them genuinely interested in who I was that we made ground in their active roles in the classes,” she said.During her time in Malaysia, Chesley also began a project of creating an English magazine with her students, she said.“I was really proud of my students for [producing the magazine] … which promoted school activities as well as what was going on in the community,” Chelsey said. “We would send it to the U.S embassy, [and it] really helped me to connect with them and get them interested.“With any post-grad service experience, you have to be open to adapt and accept and be tough-minded in your resolve with whatever can be thrown at you.”Arness had a similarly rewarding experience. She said TFA appealed to her because of the benefits it provided as well as the opportunity for service. Initially, Arness was placed in Charlotte, North Carolina, as a high school English teacher, she said.“I thought I was going to be Hilary Swank in ‘Freedom Writers,’” Arness said.But Arness was switched to teach science in a middle school shortly thereafter, she said.“I had to collaborate with other teachers, which created a huge resource exchange,” Arness said. “… There was a lot of learning and relearning. I was able to become a stronger teacher because, as my students were learning, I was as well.”Arness said her experience was most gratifying when she got to know her students.“I was involved in many after-school activities, such as an outdoors club,” she said. “It was beneficial to see them as genuine people and be involved with them outside of class.”Arness said it was important for her to define her own success, to make sure she was committed every day and to forgive herself for any mistakes she may have made, “realizing the bigger picture and remembering the mission of your program that is beyond you.”In committing to a post-graduate service program, it is essential to gather support groups and do the necessary research to know what is expected of participants, Arness said. By realizing the responsibilities of each program, one can get the most of the experience.“Who I am is very small in comparison to the impact I can make,” she said.
