Induced Nested Galactic Bars Inside Assembling Dark Matter Halos, Clayton Heller, Isaac Shlosman, Evangelie Athanassoula

Physics & Astronomy: Faculty Publications

We investigate the formation and evolution of nested bar systems in disk galaxies in a cosmological setting by following the development of an isolated dark matter (DM) and baryon density perturbation. The disks form within the assembling triaxial DM halos, and the feedback from the stellar evolution is accounted for in terms of supernovae and OB stellar winds. Focusing on a representative model, we show the formation of an oval disk and of a first generation of nested bars with characteristic subkiloparsec sizes and a few kiloparsec sizes. The system evolves through successive dynamical couplings and decouplings, forcing the gas …

Inside The Law School Classroom: Toward A New Legal Realist Pedagogy, Elizabeth Mertz

Vanderbilt Law Review

In recent years, the legal academy has been experiencing a strong renewed interest in empirical legal research. Referred to by various analysts as a "new legal realism" or as "empirical legal studies," this restored focus on the social sciences in many ways echoes an earlier era of legal realism in American law, with some important differences.' . . .

This Article combines these two themes: empirical research on law and careful examination of legal education. It reports on an empirical study of legal education, which I have been conducting under the auspices of the American Bar Foundation (a research institute …

K1 Protein Of Human Herpesvirus 8 Suppresses Lymphoma Cell Fas-Mediated Apoptosis, Suizhao Wang, Shu Wang, Hoyoung Maeng, Daniel P Young, Om Prakash, Luis E Fayad, Anas Younes, Felipe Samaniego

Faculty, Staff and Student Publications

Expression of the K1 gene of human herpesvirus 8 activates nuclear factor-kappaB and induces lymph node hyperplasia and lymphomas in transgenic mice. To further delineate its role in cell survival, we determined whether K1 altered apoptosis of lymphoma cells. K1 protein is expressed in Kaposi sarcoma and primary effusion lymphoma. We retrovirally transfected BJAB lymphoma, THP-1, U937, and Kaposi sarcoma SLK cells to express K1 and a K1 mutant with the deleted immunoreceptor tyrosine-based activation motif (K1m). We challenged cells with an agonistic anti-Fas antibody, Fas ligand, irradiation, and tumor necrosis factor-related apoptosis-inducing ligand. K1 transfectants but not K1m transfectants …

RATIONALE AND OBJECTIVES: Polyethylene glycol-coated liposomal blood pool contrast agents maintain contrast enhancement over several hours. This study aimed to evaluate (long-term) imaging of pulmonary arteries, comparing conventional iodinated contrast with a liposomal blood pool contrast agent. Also, visualization of the (real-time) therapeutic effects of tissue plasminogen activator (t-PA) on pulmonary embolism (PE) was attempted. MATERIALS AND METHODS: Six rabbits (weight approximately 4 kg) had autologous blood clots injected through the superior vena cava. Imaging was performed using conventional contrast (iohexol, 350 mg I/ml; GE HealthCare, Princeton, NJ) at a dose of 1400 mg I per animal, and after wash-out, …

Protection Against Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Infection Through Passive Transfer Of Prrsv-Neutralizing Antibodies Is Dose Dependent, O. J. Lopez, M. F. Oliveira, E. Alvarez Garcia, Byung Joon Kwon, Alan R. Doster, Fernando A. Osorio

Nebraska Center for Virology: Faculty Publications

Previous work in our laboratory demonstrated that passive transfer of porcine reproductive and respiratory syndrome virus (PRRSV)-neutralizing antibodies (NA) protected pregnant sows against reproductive failure and conferred sterilizing immunity in sows and offspring. We report here on the dose requirement for protection by passive transfer with NA in young weaned pigs. The presence of a 1:8 titer of PRRSV-NA in serum consistently protected pigs against viremia. Nevertheless, their lungs, tonsils, buffy coat cells, and peripheral lymph nodes contained replicating PRRSV similar to the infected control group. Likewise, these animals excreted infectious virus to sentinels similar to the infectivity control animals. …

2006–2007 Christmas Bird Counts In Nebraska

Nebraska Bird Review

Despite snow and ice storms which forced postponement of several counts and prevented participation by a number of birders, all 14 counts which were held last winter took place again this winter. The total number of species (131) was two more than last year's 129, and the total number of individuals was 177,590, down some 30,000.

Waterfowl numbers were about normal. Canada Goose numbers were down 16,000 from last year, but this is a number which fluctuates on that scale from year to year. Northern Pintails are becoming more abundant on Christmas Counts. Their tallies in the early 1990s were …

Comparison Of Sampling Strategies To Estimate Abundance Of Double-Crested Cormorants In Western Mississippi, Aaron T, Pearse, Brian S. Dorr, Stephen J. Dinsmore, Richard M. Kaminski

United States Department of Agriculture Wildlife Services: Staff Publications

We compared 2 sampling strategies designed to estimate abundance of double-crested cormorants (Phalacrocorax auritus, hereafter cormorants) on aquaculture ponds in western Mississippi. Cormorants are a major predator of cultured channel catfish (lctalurus punctatus) in this region; thus, estimating cormorant abundance is needed to better determine their economic impact We independently designed a species-specific survey (i.e., cluster sampling) and a general survey (i.e., transect sampling) based on robust probability sampling theory to estimate abundance of this target population. During winters 2002-2003 and 2003-2004, we conducted 8 pairs of surveys and compared estimates of cormorant abundance and associated …

The Time Invariance Principle, Ecological (Non)Chaos, And A Fundamental Pitfall Of Discrete Modeling, Bo Deng

Department of Mathematics: Faculty Publications

This paper is to show that most discrete models used for population dynamics in ecology are inherently pathological that their predications cannot be independently verified by experiments because they violate a fundamental principle of physics. The result is used to tackle an on-going controversy regarding ecological chaos. Another implication of the result is that all continuous dynamical systems must be modeled by differential equations. As a result it suggests that researches based on discrete modeling must be closely scrutinized and the teaching of calculus and differential equations must be emphasized for students of biology.

Theileria Electrophori N.Sp., A Parasite Of The Electric Eel Electrophorus Electricus (Osteichthyes: Cypriniformes: Gymnotidae) From Amazonian Brazil, Ralph Lainson

Harold W. Manter Laboratory of Parasitology: Library Materials

The name Theileria electrophori n. sp. is proposed for a small parasite described in the erythrocytes of the electric eel, Electrophorus electricus, from Amazonian Brazil. Division of the organism in the erythrocyte produces only four bacilliform daughter cells which become scattered in the host cell, without a cruciform or rosette-shaped disposition. Exoerythrocytic meronts producing a large number of merozoites were encountered in Giemsa-stained impression smears of the internal organs, principally in the liver, and are presumably the source of the intraerythrocytic forms of the parasite. This developmental pattern is characteristic of piroplasms within the family Theileriidae, where the author …

The Molecular Basis Of High-Altitude Adaptation In Deer Mice, Jay F. Storz, Stephen J. Sabatino, Federico G. Hoffmann, Eben J. Gering, Hideaki Moriyama, Nuno Ferrand, Bruno Monteiro, Michael W. Nachman

Hideaki Moriyama Publications

Elucidating genetic mechanisms of adaptation is a goal of central importance in evolutionary biology, yet few empirical studies have succeeded in documenting causal links between molecular variation and organismal fitness in natural populations. Here we report a population genetic analysis of a two-locus a-globin polymorphism that underlies physiological adaptation to high-altitude hypoxia in natural populations of deer mice, Peromyscus maniculatus. This system provides a rare opportunity to examine the molecular underpinnings of fitness-related variation in protein function that can be related to a well-defined selection pressure. We surveyed DNA sequence variation in the duplicated α -globin genes of P. maniculatus …

The Role Of Human Papillomavirus Infection In Prostate Cancer, Jaudah A. Al-Maghrabi

Saudi Medical Journal

Human papillomavirus HPV is the cause of the most common sexually transmitted diseases STDs of viral etiology worldwide. High-risk HPVs are the etiological agents of cervical and other anogenital malignancies and low-risk HPVs induce only benign genital warts. Since high-risk HPVs have been shown to possess oncogenic potential, an association between HPV infection and prostatic carcinoma Pca has been suggested. Some authors demonstrated that HPV infection play an important role in the pathogenesis of Pca. Active research is ongoing to highlight the mechanisms by which HPV involved in the development of cancer. The aim of this article is to review …

OBJECTIVE: Malnutrition occurs frequently in cancer patients and is multifactorial and can lead to negative outcomes. So we studied the effect of radiotherapy on nutritional status, weight changes, dietary intake, serum zinc and copper levels. METHODS: During the period of October to March 2005, 45 cancer patients who referred to the Radiotherapy Center, Imam Khomeini Hospital, Iran were recruited. We assessed the nutritional status of patients using Patient-Generated Subjective Global Assessment (PG-SGA) questionnaire. Patients on the basis of location of radiotherapy classified to mediastinum, head and neck and pelvic groups. Changes in dietary intake (using 24-hour recall method) and body …

On Logic In The Law: Something, But Not All, Susan Haack

Articles

In 1880, when Oliver Wendell Holmes (later to be a Justice of the U.S. Supreme Court) criticized the "logical theology" of law articulated by Christopher Columbus Langdell (the first Dean of Harvard Law School), neither Holmes nor Langdell was aware of the revolution in logic that had begun, the year before, with Frege's Begriffsschrift. But there is an important element of truth in Holmes's insistence that a legal system cannot be adequately understood as a system of "axioms and corollaries"; and this element of truth is not obviated by the more powerful logical techniques that are now available.

The acronym …

Terrorism And Trial By Jury: The Vices And Virtues Of British And American Criminal Law, Laura K. Donohue

Georgetown Law Faculty Publications and Other Works

British tradition and the American Constitution guarantee trial by jury for serious crime. But terrorism is not ordinary crime, and the presence of jurors may skew the manner in which terrorist trials unfold in at least three significant ways. First, organized terrorist groups may deliberately threaten jury members so the accused escapes penalty. The more ingrained the terrorist organization in the fabric of society, the greater the degree of social control exerted under the ongoing threat of violence. Second, terrorism, at heart a political challenge, may itself politicize a jury. Where nationalist conflict rages, as it does in Northern Ireland, …

Cyber-Trespass And 'Unauthorized Access' As Legal Mechanisms Of Access Control: Lessons From The Us Experience, Mary W. S. Wong

Research Collection Yong Pung How School Of Law

The common law doctrine of trespass to chattels has recently been revived and applied by courts in the United States (US) to cover intrusions (in the form of electronic signals) to computer systems connected to the Internet. These cases represent judicial recognition of the need to protect certain unwanted intrusions in cyberspace, though the principles developed therewith are remarkably expansive. As such, they overlap with the concept of ‘unauthorized access’ under computer misuse legislation in the US and elsewhere. This overlap has yet to be judicially acknowledged. Since the US, the United Kingdom and other common law countries not only …

Congenital Oesophageal Stenosis In A Puppy, Churee Pramatwinai

The Thai Journal of Veterinary Medicine

An extremely rare case of congenital oesophageal stenosis in a two-month-old, male, miniature pincher dog was reported. The puppy was presented at the Small Animal Teaching Hospital, Faculty of Veterinary Science, Chulalongkorn University, with a history of an acute onset of regurgitation at the time of weaning on to solid food. Contrast radiography of the oesophagus showed that the oesophagus at the cervical and thoracic-inlet portions was moderately dilated. Upon oesophagoscopic examination, the oesophageal lumen adjacent to the heart base showed intraluminal stenosis. The mucosa was normal and the stenotic opening was localized at the center of the lumen. Upon …

Backlash's Travels, Cass R. Sunstein

Public Law and Legal Theory Working Papers

Sometimes the public greatly opposes the decisions of the Supreme Court; sometimes the Court seems to anticipate public backlash and even to respond to it when it occurs. Should a social planner want the Court to anticipate or to respond to backlash? No abstract answer is possible; the appropriate conclusion depends on assumptions about the capacities of courts and the capacities of those who engage in backlash. This point is demonstrated through an exploration of four imaginable worlds: Olympus, the Land of the Ancients, Lochnerland, and Athens. The four worlds reflect radically different assumptions about judicial and public capacities. The …

Combining Historical Research And Narrative Inquiry To Create Chronicles And Narratives, Richard A. Wilson

The Qualitative Report

Stories about the Idaho State Library, chronicles and narratives, are reported in my doctoral dissertation (Wilson, 2005). The chronicles, reconstructed from documents and records, provided a presentation of the people, events, and activities to frame the stories. The narratives, excerpted from interviews, provided the rich description and unique perspectives of the two living State Librarians who directed the agency between 1962 and 2005. The focus of this paper is a presentation and discussion of the use of historical research and narrative inquiry to create chronicles and narratives.
