One of the remarkable tectonic features of the Earth’s crust is the widespread presence of long, approximately straight and geomorphically prominent strike-slip faults which are a kinematic consequence of large-scale motion of plates on a sphere (Wilson 1965). Strike-slip faults form in continental and oceanic transform plate boundaries; in intraplate settings as a continental interior response...

A detailed simulation of air showers produced by dust grains has been performed by means of the aires Monte Carlo code with the aim of comparing with experimental data. Our analysis indicates that extensive dust grain air showers must yet be regarded as highly speculative but they cannot be completely ruled out. PACS number(s): 98.70.Sa, 98.70.-f

On Friday afternoon I had the opportunity to try my hand at blacksmithing while I was attending a museum conference at the Farmer's Museum in Cooperstown. Although I was an industrial arts student at SUNY Oswego many years ago, I never enrolled in metal shop so this was my first encounter with a forge. My first task was to make a nail. As simple as it might appear, there are techniques that hav...

Michael Wheeler opens his book with the following half-apology: “striking while the iron is lukewarm is sometimes the best strategy in philosophy” (Preface, p. x). He is referring to the fact that the main task of this book—to ferret out and critically assess the Cartesian legacy in contemporary cognitive science, replacing it (or at least altering it to better conform) with a philosophy of min...

Address for reprints: Dr. Carlos Labadet Av. Almirante Brown 240 CABA e-mail: [email protected] A BIT OF HISTORY Historically, premature ventricular contractions (PVCs) were considered precursors of sudden cardiac death and, for many years, their mere presence was taken as an indication for prescribing antiarrhythmic agents. The concept that ventricular fibrillation (VF) and ventricular tachyc...

We develop a model of wage bargaining with private information in a duopoly. We investigate how product differentiation and market competition (Bertrand vs. Cournot competition) affect wages and strikes. If bargaining takes place at the industry-level, then both the wage outcome and the strike activity do not depend on the degree of product differentiation whatever the type of market competitio...

We consider a two-country model of wage determination with private information in unionized, imperfectly competitive, industries. We investigate the effects of opening up markets to trade as well as of further market integration on the negotiated wage and the maximum delay in reaching an agreement. From an initial situation of two-way intraindustry trade, an increase in product market integrati...

We evaluated the influence of the trench-parallel component of plate motion on the active fault system within the Nankai accretionary wedge from reflection seismic profiles, high-resolution seafloor bathymetry, and deep-towed sub-bottom profiles. Our study demonstrated that a large portion of the trench-parallel component of oblique plate subduction is released by strike-slip motion along a fau...

Fly strike in sheep has been estimated to cost the Australian sheep industry approximately $280m dollars annually (Sackett et al. 2006) as a result of sheep losses, cost of treatment and loss of wool and carcase production and value. Historically Australian sheep producers have surgically removed skin from around the tail (mulesing) to help avoid fly strike. Although this has proved highly succ...

Heel strike detection is an important cue for human gait recognition and detection in visual surveillance since the heel strike position can be used to derive the gait periodicity, stride and step length. We propose a novel method for heel strike detection using a gait trajectory model, which is robust to occlusion, camera view and to low resolution which can generalize to a variety of surveill...
