Unconditional preparation of entanglement between atoms in cascaded optical cavities

We propose a scheme to unconditionally entangle the internal states of atoms trapped in separate high finesse optical cavities. The scheme uses the technique of quantum reservoir engineering in a cascaded cavity QED setting, and for ideal (lossless) coupling between the cavities generates an entangled pure state. Highly entangled states are also shown to be possible for realizable cavity QED parameters and with nonideal coupling.Comment: 4 pages, 5 figures, submitted to Physical Revie

Quantitative imaging of the collective cell movements shaping an embryo

The recent development of imaging and image processing techniques, such as 4D microscopy and 3D cell tracking, enables analysis through quantification of the movement of large cell populations in vivo. These imaging approaches provide an opportunity to study embryonic morphogenesis during development from the level of cellular processes to the scale of entire organism. Image analysis reveals cell collective behaviors that shape an embryo and offers some surprising insights into the cell-cell interactions involved in concerted movements. We illustrate the power of this approach by studying the early development of Drosophila embryos

Are male orangutans a threat to infants? Evidence of mother-offspring counter strategies to infanticide in Bornean orangutans (Pongo pygmaeus wurmbii)

Sexually selected infanticide by males is widespread in primates. Female primates employ a variety of strategies to reduce infanticide risk. While infanticide has never been directly observed in wild orangutans (Pongo spp.), their slow life history makes infants vulnerable to infanticide. The mating strategies of female orangutans include polyandrous and postconceptive mating that may serve to increase paternity confusion, an infanticide avoidance strategy. Here, we investigate whether female orangutans alter their social interactions with males as another infanticide avoidance strategy. We hypothesize that females with younger offspring avoid males and that the distance between mother and offspring decreases in the presence of males. We use long-term behavioral data collected between 1994 and 2016 from Bornean orangutans (Pongo pygmaeus wurmbii) in Gunung Palung National Park, Indonesia, to test whether the sexual selection hypothesis for infanticide helps explain aspects of orangutan social behavior. We found that mothers with offspring 6 yr. old and females without offspring. In addition, the distance between a mother–offspring dyad showed a statistically significant decrease in the presence of males, but not females. Our results are consistent with the hypothesis that female orangutans employ strategies to reduce infanticide risk in their social interactions. Because orangutans have a high fission–fusion dynamic, they have flexibility in manipulating social interactions as a counter-infanticide strategy. Our results suggest that infanticide by males is a selective pressure shaping female orangutan social behavior.Accepted manuscrip

Framing Collaboration: Archives, IRs, and General Collections

Collaborative collecting highlights the opportunity for liaison librarians and archivists in academic libraries to develop an integrated and holistic approach to the successful collection of library materials. Yet as academic libraries become the central location for general collections, institutional repositories, university archives, manuscript collections, and other special collections, the world of collecting in academic libraries becomes more siloed. The profession stands to benefit from a stronger realization of shared collecting practices. Liaison librarians have the potential to provide critical information to archivists in support of faculty collecting and research. Archivists have the opportunity to provide liaison librarians with context about university units and the organization’s broader history. Shared information can result in more robust collecting policies and practices across the library

Art and Medicine: A Collaborative Project Between Virginia Commonwealth University in Qatar and Weill Cornell Medicine in Qatar

Four faculty researchers, two from Virginia Commonwealth University in Qatar, and two from Weill Cornell Medicine in Qatar developed a one semester workshop-based course in Qatar exploring the connections between art and medicine in a contemporary context. Students (6 art / 6 medicine) were enrolled in the course. The course included presentations by clinicians, medical engineers, artists, computing engineers, an art historian, a graphic designer, a painter, and other experts from the fields of art, design, and medicine. To measure the student experience of interdisciplinarity, the faculty researchers employed a mixed methods approach involving psychometric tests and observational ethnography. Data instruments included pre- and post-course semi-structured audio interviews, pre-test / post-test psychometric instruments (Budner Scale and Torrance Tests of Creativity), observational field notes, self-reflective blogging, and videography. This book describes the course and the experience of the students. It also contains images of the interdisciplinary work they created for a culminating class exhibition. Finally, the book provides insight on how different fields in a Middle Eastern context can share critical /analytical thinking tools to refine their own professional practices

A Commerce Clause Challenge to New York\u27s Tax Deduction for Investment in Its Own Tuition Savings Program

The Internal Revenue Code provides guidelines for states to create and maintain college tuition savings programs which offer federal tax benefits to investors. Several states have enacted tuition savings plans in accordance with these guidelines. In addition to the federal tax benefits allowed, New York offers a state tax deduction to New York residents who invest in its plan, the New York College Choice Tuition Savings Program. New York does not offer the deduction, however, to residents who invest in comparable programs offered by other states. The tax deduction thus creates an incentive for residents to invest in the in-state program and discriminates against interstate investment in the tuition programs offered by other states. This Note argues that the incentive created by the New York tax deduction violates the United States Constitution by discriminating against interstate commerce

BODY SIZE INDICATORS AND THE EXAMINATION OF STRESS FROM A GROWTH AND DEVELOMENT PERSPECTIVE: A NEW METHOD OF BIOARCHAEOLOGICAL ASSESSMENT

The purpose o f this thesis research is to introduce a new method to examine childhood stress episodes from adult skeletal remains. Through the use of indicators of adult body size and regression analysis, stress patterns were analyzed in two climatically different populations, the Sadlermiut Inuit of Southampton Island and the Sacred Heart Cemetery population from southwestern Ontario. By comparing body size indicators to one another in sequential order, it was possible to assess at what time during growth and development that certain individuals deviated from their normal growth patterns and experienced stress. As expected, the Sadlermiut and Sacred Heart samples demonstrated different stress patterns that can be linked to the different environmental contexts in which they lived. This research demonstrated the potential utility o f this new methodology and the use o f growth and development patterns to assess stress, especially when considered in conjunction with other methods

A Quantitative Examination of Title I and Non-Title I Elementary Schools in East Tennessee Using Fourth-Grade Math and Reading Standardized Test Scores.

In January 2002, President George W. Bush signed the No Child Left Behind legislation into law. The law established new standards of accountability for individual students, schools, and school systems. Because of No Child Left Behind, the penalties for schools with poor academic performance in our country are the loss of reputation, student enrollment, and financial support. The purpose of this study was to determine if there was a difference in standardized test scores in reading and math between fourth-grade students in Title I schools and those in NonTitle I schools. The study focused on the following subgroups: gender, economically disadvantaged students, and students with disabilities. The data were gathered from an analysis of standardized test scores in reading and math of fourth-grade students in 172 elementary schools located in 21 East Tennessee school systems. The data were collected from the 2002-2003 Terra Nova Standardized Assessment Test scores. The Terra Nova test is a standardized test used to evaluate academic progress in the state of Tennessee. In summary, there were some differences between Title I and NonTitle I fourth-grade students in the subject areas of reading and math. Significant differences were noted within the subcategory of gender in both reading and math. Significant differences were also noted within the subcategory of students with disabilities in the content area of math. No significant differences were found in reading for students with disabilities. There were no significant differences between Title I and NonTitle I schools in reading and math within the subcategory of economically disadvantaged students
