Steven Hsiao Hopkins neuroscientist Steven Hsiao, one of the world’s leading experts on the neural basis of touch, passed away on June 16, 2014 at the age of 59 from lung cancer. Steve, the heir of an eminent line of sensory neuroscientists that included Vernon B. Mouncastle and Kenneth O. Johnson, sought to understand the neural code: how do spatio-temporal patterns of activity along the neura...

The HLA D/DR region of the human major histocompatibility complex encodes a family of highly polymorphic, human "Ia-like" molecules that function as genetic restriction elements in a variety of immune phenomena (1, 2). Correlations have been demonstrated between disease susceptibility and particular HLA D/DR antigens (1, 3, 4). Recent evidence (5-7) has demonstrated a considerable heterogeneity...

Steven Kohm reviews Just One Rain Away: The Ethnography of River-City Flood Control by Stephanie C Kane

In 1998, Allouche, Peyrière, Wen and Wen established that the Hankel determinants associated with the Thue–Morse sequence on {−1, 1} are always nonzero. Their proof depends on a set of sixteen recurrence relations. We present an alternative, purely combinatorial proof of the same result. We also re-prove a recent result of Coons on the non-vanishing of the Hankel determinants associated to two ...

It is often necessary to be able to create computer models from physical objects. This is often done for the purposes of reverse engineering, or archival. Many of the contact methods, such as callipers or Coordinate Measuring Machines, are unsuitable for use in areas where the material is delicate. There are numerous techniques that are capable of performing quick accurate measurements of surfa...

Given three regular space curves r1(t), r2(t) r3(t), t ∈ [ 0, 1 ] that define a curvilinear triangle, we consider the problem of constructing a C triangular surface patch R(u1, u2, u3) bounded by these three curves, such that they are geodesics of the constructed surface. Results from a prior study [6] concerned with tensor–product patches are adapted to identify constraints on the given curves...
