Shelby's manslaughter trial begins Monday, May 8, 2017 in the shooting of Terence Crutcher, an unarmed black man. (AP Photo/Sue Ogrocki, File) TULSA, Okla. (AP) — Jurors hearing the manslaughter case against a white Oklahoma police officer accused of fatally shooting an unarmed black man last year will be asked to decide whether she used appropriate force — a question that's been put to juries around the U.S. in other similar trials. Tulsa officer Betty Jo Shelby is accused of overreacting when she shot 40-year-old Terence Crutcher in September. Prosecutors say Crutcher wasn't armed or combative when Shelby approached him on a street after his SUV broke down and that he obeyed Shelby's commands to raise his hands. Shelby's attorneys say she feared for her life, believing he was reaching into his vehicle for a gun. Crutcher is among at least 20 black people in the U.S. who have died after police encounters in the past several years. The killings have galvanized the Black Lives Matter movement, which called on citizens to demand more accountability from law enforcement. Shelby, who has been on unpaid leave, faces four years to life in prison if convicted. Her trial starts Monday. Some key elements of the case: Shelby came upon Crutcher's stalled SUV while on her way to a domestic violence call. Police video shows Crutcher walking away from Shelby toward his vehicle with hands above his head. The footage doesn't offer a clear view of when Shelby shot Crutcher. Her attorneys say that in the two minutes before cameras began recording the encounter, Shelby repeatedly ordered Crutcher to stop walking away from her and get on the ground. Shelby also said she feared Crutcher was under the influence of PCP, a powerful hallucinogenic known as Angel Dust that makes users erratic, unpredictable and combative. "Her options went to zero when he turned and put his hand in the car," defense attorney Shannon McMurray said. An autopsy showed PCP was in Crutcher's system, and police said they found a vial of it in his SUV. Crutcher's family said police attempted to "demonize" Crutcher over the drug possession to deflect attention from the fact officers didn't find a gun inside his SUV. "His hands were up, there was daylight, everyone can clearly see that he had no weapon in his hand whatsoever," Crutcher's twin sister, Tiffany Crutcher, told The Associated Press in September. Tulsa County District Attorney Steve Kunzweiler charged Shelby with first-degree manslaughter six days after the shooting. An affidavit accused her of "becoming emotionally involved to the point that she overreacted." McMurray argued that prosecutors rushed to charge Shelby for political reasons, fearing civil unrest like the angry street protests that erupted in Charlotte, North Carolina, after the fatal shooting of 43-year-old Keith Lamont Scott four days after Crutcher was killed. The Justice Department also opened a civil rights investigation into Crutcher's death. Loretta Radford, the acting U.S. attorney for the Northern District of Oklahoma, declined to comment on the case. Crutcher's backing partner, Tyler Turnbough, deployed his stun gun on Crutcher even as Shelby was firing her handgun, and prosecutors have questioned why Shelby didn't do the same. But Turnbough told the nonprofit National Center for Police Defense that Shelby followed protocol, especially if she suspected Crutcher was under the influence of a mind-altering drug. "Officer Shelby's reaction was appropriate and necessary," he told the nonprofit, which provides medical and legal aid to officers in similar cases. "There is no way of knowing what he was reaching for and to take a chance could be deadly." The nonprofit estimated last month that it had raised about $100,000 for Shelby's cost-of-living expenses. How Shelby and Turnbough each assessed the situation illustrates the dilemma officers face when "someone can go from unarmed to armed" in seconds, said Louis Laguna, a professor of forensic psychology at Lebanon Valley College in Annville, Pennsylvania. "It's a Catch-22 really, because it's almost impossible to kind of go back and Monday morning quarterback it," said Laguna, a former police officer. A judge in April reprimanded Shelby and her attorneys after she talked about her case on national TV. Shelby, 43, told CBS' "60 Minutes" that Crutcher appeared to reach inside his SUV for a weapon and ignored her commands to stop. "I say with a louder, more intense voice, 'Stop. Stop! Stop!' And he didn't. And that's when I took aim," she said.

d-Limonene, a cyclic terpene that is a major component of several plant essential oils, is used widely as an additive in perfumes, soaps, foods and beverages, and has also been shown to possess chemopreventative and chemotherapeutic activity. A limited number of studies have been conducted investigating the effect of d-limonene on immune system function. We show that d-limonene and its metabolites limonene-1-2-diol and perillic acid inhibit the production by CD3+CD4+ T cells of IFN-γ, IL-2, TNF-α, IL-4 and IL-13, and the production by CD3+CD8+ T cells of IFN-γ, IL-2, and TNF-α. Additionally, the upregulation of CD25, CD69 and CD40L by activated T lymphocytes is modulated by d-limonene, limonene-1-2-diol and perillic acid treatment. Furthermore, high concentrations of d-limonene, limonene-1-2-diol and perillic acid induce T lymphocyte cell death. These data suggest that d-limonene possesses immunomodulatory activity that must be considered when utilizing the compound for therapeutic or commercial purposes. © 2012 Elsevier Inc.

Due to their characteristic physical, chemical and optical properties, titanium dioxide and silver nanoparticles are attractive tools for use in a wide range of applications. The use of nanoparticles for biological applications is, however, dependent upon their biocompatibility with living cells. Because of the importance of inflammation as a modulator of human health, the safe and efficacious in vivo use of titanium dioxide and silver nanoparticles is inherently linked to a favorable interaction with immune system cells. However, both titanium dioxide and silver nanoparticles have demonstrated potential to exert immunomodulatory and immunotoxic effects. Titanium dioxide and silver nanoparticles are readily internalized by immune system cells, may accumulate in peripheral lymphoid organs, and can influence multiple manifestations of immune cell activity. Although the factors influencing the biocompatibility of titanium dioxide and silver nanoparticles with immune system cells have not been fully elucidated, nanoparticle core composition, size, concentration and the duration of cell exposure seem to be important. Because titanium dioxide and silver nanoparticles are widely utilized in pharmaceutical, commercial and industrial products, it is vital that their effects on human health and immune system function be more thoroughly evaluated. © 2015 Elsevier Ltd.

The symmetric Werner states for n qubits, important in the study of quantum nonlocality and useful for applications in quantum information, have a surprisingly simple and elegant structure in terms of tensor products of Pauli matrices. Further, each of these states forms a unique local unitary equivalence class, that is, no two of these states are interconvertible by local unitary operations. © 2011 American Physical Society.

We classify, up to local unitary equivalence, local unitary stabilizer Lie algebras for symmetric mixed states of n qubits into six classes. These include the stabilizer types of the Werner states, the Greenberger-Horne-Zeilinger state and its generalizations, and Dicke states. For all but the zero algebra, we classify entanglement types (local unitary equivalence classes) of symmetric mixed states that have those stabilizers. We make use of the identification of symmetric density matrices with polynomials in three variables with real coefficients and apply the representation theory of SO(3) on this space of polynomials. © 2011 American Physical Society.

Ecological Economics | Year: 2010
Using the Noah's Ark problem - the problem of efficiently allocating limited funds to conserve biodiversity - the standard economic approach to endangered species conservation constructs a human-centered biodiversity by favoring species directly valuable to humans. I analyze this approach and draw on the functional ecology literature to offer an alternative emphasizing the role species play in their ecosystems. The aim is to create a working ecosystem on the Ark rather than a collection of charismatic and distinct species. To do so, I construct a new measure of a species' ecological importance and an ecological objective appropriate for cost-effective resource allocation. The ecological approach fundamentally changes the notion of species-value from a direct value based on a species' appearance or taxonomic difference to an indirect value based on a species' ecological role in its ecosystem. In the process, 'populations' of species become the fundamental unit of biodiversity rather than 'species', and abiotic processes also possess value. When compared to the economic approach, the ecological approach prioritizes different species for the Ark and achieves superior economic outcomes in all but the mythical Noah's Ark scenario where interactions are non-existent. The analysis challenges the approach of US endangered species legislation and I call for a reformulation based on endangered ecological interactions. © 2009 Elsevier B.V. All rights reserved.

Many emerging quantum information technologies require access to some form of quantum entanglement in order to operate. Understanding what is needed and what is possible to achieve with these technologies is frustrated by the large number of types of multiparticle entanglement that could be produced. The role of multiparticle quantum entanglement as a resource and the proliferation of entanglement types with increasing particle numbers motivate a program of classification. A good classification scheme provides a framework for understanding properties of and relationships among quantum states, puts interesting states in a context, and introduces concepts that allow explanation and interpretation of new findings. The goals of this research are to produce such a classification scheme, and to use the resulting knowledge about the structure of quantum states in applications of interest in quantum computation, communication, and cryptography.
This project will provide a framework and a language in which to articulate the needs and resources of quantum information processing tasks, and will therefore be of use to researchers trying to make these tasks a reality. A second broader impact of this project is direct influence on the scientific careers of promising young students. Undergraduates will participate as research assistants who will carry out computational experiments, write computer code to generate examples and test hypotheses, and prove special cases of broad conjectures. Engagement in research teaches the process of intellectual inquiry and discovery in a way that classroom work alone cannot achieve. This project will strengthen the research environment at Lebanon Valley College by supporting students in research activities including presentations at scientific meetings and publications in scientific journals.

This U.S.-Hungarian International Research Experiences for Students (IRES) project supports undergraduate students research visits to Budapest, Hungary, for an immersive collaboration with Hungarian mentors and students. With overall direction by the Principal Investigator, Dr. Timothy Peelen of Lebanon Valley College, twelve U.S. students from the mid-Atlantic region, work in laboratories at Eötvös Loránd University guided by two lead Hungarian mentors, Drs. Zoltán Novák and Péter Kele. Prior to departure, all students prepare for their eight week research experience abroad during a two week orientation at Lebanon Valley College to learn about Hungarian culture and language, and for instruction in concepts and techniques related to fundamental applications of light energy, spanning organometallic and bioorthogonal chemistry. In Budapest, students work in the Novák and Kele laboratories on a cluster of activities centered around the theme of applications of light energy. While designed around this unifying theme, specific projects allow participants to pursue individual interests in the areas of inorganic, organic, photophysical, and biological chemistry. Each of the IRES undergraduate participants also gains experience with the application of chemical tools that can be used to manipulate the photophysical properties of metal complexes and fluorogenic probes for applications in photoredox catalysis and bioorthogonal chemistry, respectively.
Overall, IRES activities at Eötvös Loránd University offer a valuable early immersive research experience that will prepare the undergraduate researchers to engage productively with international colleagues as they pursue their future careers. The P.I. will reach out to serve different underrepresented groups, including a commitment to select equal numbers of male and female participants while striving to include underrepresented minorities and students with disabilities. Participation in a rigorous research project as an undergraduate has been linked to important gains such as thinking and working like a scientist and clarification of career or graduate school plans. As a capstone experience for the program, IRES students will be strongly encouraged to participate in the Undergraduate Research Symposium in the Chemical and Biological Sciencesheld each October at Unniversity of Maryland, Baltimore Campus.

Cytokinins are plant hormones that play an integral role in multiple aspects of plant growth and development. The biological functions of cytokinins in mammalian systems are, however, largely uncharacterized. The naturally occurring cytokinin zeatin riboside has recently been demonstrated to activate the mammalian adenosine A2A receptor, which is broadly expressed by various cell types including immune system cells, with the activation of the A2AR playing a role in the regulation of cells involved in both innate and adaptive immunity. We show for the first time that zeatin riboside modulates mammalian immune system activity via an A2AR-dependent mechanism. Specifically, zeatin riboside treatment induces the production of cyclic adenosine monophosphate (cAMP) by T lymphocytes and inhibits the production by CD3 + CD4 + T cells of interferon (IFN)-γ, IL-2, tumor-necrosis factor (TNF)-α, IL-4 and IL-13, and the production by CD3 + CD8 + T cells of IFN-γ, IL-2 and TNF-α. Additionally, the upregulation of CD25, CD69 and CD40L by activated T lymphocytes is modulated by zeatin riboside. Zeatin riboside treatment also potently inhibits thioglycollate-induced peritoneal leukocytosis. The immunomodulatory activities of zeatin riboside are blocked by co-treatment with the selective A2AR antagonist ZM241385. These data suggest that zeatin riboside possesses therapeutic potential as a mammalian immunomodulatory agent. © 2015 CSI and USTC.
