Cardiovascular ephrinB2 function is essential for embryonic angiogenesis

EphrinB2, a transmembrane ligand of EphB receptor tyrosine kinases, is specifically expressed in arteries. In ephrinB2 mutant embryos, there is a complete arrest of angiogenesis. However, ephrinB2 expression is not restricted to vascular endothelial cells, and it has been proposed that its essential function may be exerted in adjacent mesenchymal cells. We have generated mice in which ephrinB2 is specifically deleted in the endothelium and endocardium of the developing vasculature and heart. We find that such a vascular-specific deletion of ephrinB2 results in angiogenic remodeling defects identical to those seen in the conventional ephrinB2 mutants. These data indicate that ephrinB2 is required specifically in endothelial and endocardial cells for angiogenesis, and that ephrinB2 expression in perivascular mesenchyme is not sufficient to compensate for the loss of ephrinB2 in these vascular cells

Where Have You Hidden the Cholera?

Rowan Moore Gerety, a reporter and author from New York, will speak out about the root causes of the mistrust and violence faced by efforts to stop the spread of cholera in Mozambique, which are part of a larger pattern of violent resistance to public health campaigns around the world. The talk will be based on the chapter Where have you hidden the cholera? in Gerety\u27s book Go Tell the Crocodiles: Chasing Prosperity in Mozambique.https://egrove.olemiss.edu/croft_spe/1009/thumbnail.jp

Wireless Distance-Verifying Security System for ID Card/Document Enrollment Stations

Modern ID Cards and passports have evolved into sophisticated, complex positive-ID instruments that embody a wide variety of anti-cloning and anti-forgery techniques, such as: digitized biometrics, micro-printing, encryption, RFID, embedded processing, holo-graphic overlays, and UV/IR-visible features, among others. This poster describes a practical system for protecting against theft of the enrollment stations that produce these ID instruments, by providing a "lock" to a specific location. If a protected enrollment system is moved from that location, it will fail to function. This non-GPS location-locking technique is strongly protected against sniffing and spoofing, is immune to relay attacks, and cannot be copied - not even by its manufacturer

High-Security, Clone-proof RFID with Secure Distance Bounding

Wireless near-field (NFC) and short-range RFID “security” devices are ubiquitous, commonly found in vehicle security (keyless-entry, remote-start), access control (employee key cards), travel cards, point-of-sale (PoS) transactions via NFC-enabled mobile phone or credit card, among others. Whenever assets of high-value are at stake, adversaries will stop at nothing to gain access to those assets, so it should be assumed that security systems will be subjected to many forms of attack. There have already been several highly publicized successful breaches of keyless entry systems, including relay and key-cloning attacks. This poster describes a a highly-secure, distance-bounding, clone-proof RFID mechanism for protecting high-value assets. The system employs a unique combination of technologies to make it highly-resistant to relay attacks, probing, modeling, cloning and snooping

Context-Free Decoding of High-Density 2D Bit Fields with Alias Disambiguation

PROBLEM: Conventional decoding techniques tend to operate exclusively in the space domain and often rely on code-specific “finder features,” ECC, high-resolution imaging, image resampling (a “lossy” process), encoded data “clues” and low code density relative to image resolution (see EASY examples below). This limits the amount of information that can be reliably encoded into a given area. RESEARCH OBJECTIVES: Recover randomly-oriented 2D bit fields without resampling, without reliance on finder features, and without dependency on encoding or data content. Decode at image densities that produce aliasing of primary grid frequencies – alias disambiguation (see HARD example below). Provide linear code density improvement of 1.5:1 to 2:1 over conventional techniques, resulting in an increase in data density per unit area of 2.25:1 to 4:1

Trial Bench Views: IAALS Report on Findings From a National Survey on Civil Procedure

In the spring of 2010, the Institute for the Advancement of the American Legal System (“IAALS”) collected survey data on the American civil justice system from state and federal judges throughout the United States, as part of a joint effort with Northwestern University School of Law’s Searle Center on Law, Regulation, and Economic Growth (“Searle Center”). This report sets forth the collective opinions of respondent judges, as they bear on civil reform proposals developed by IAALS and the American College of Trial Lawyers Task Force on Discovery and Civil Litigation (“ACTL Task Force”)

Defining Character: A Curriculum Analysis of the Boy Scouts of America and the National Kappa League

Since the early 2000s and the dawn of No Child Left Behind and standards based accountability character education has been neglected and for the most disappeared. Many school districts can no longer justify spending part of students’ school day discussing character. Some character education remains, however, it is often only addressed in health, student financing, and college and career readiness. Most other character education programs have been contracted out. Schools now rely on community partners to help students develop values and morals. This thesis will examine two of these community partners: the Boy Scouts of America and the National Kappa League. Evaluation of these organizations’ curricula will answer the following questions. First, how do the Boy Scouts of America and the National Kappa League define character? Is there a connection between their definition of character and masculinity? Last, if there are differences between the two curricula, what do these differences say about race, and masculinity
