The beam-based alignment algorithm for the NLC main linac requires that the magnetic-electrical offset between the center of each BPM and the center of its quadrupole be determined with an absolute accuracy on the order of microns via quadrupole shunting; this allows the quads to be moved such that the beam is passing through the quad centers to this accuracy. In this note we consider the range...

The recent article “Intrapulmonary Shunt Is a Potentially Unrecognized Cause of Ischemic Stroke and Transient Ischemic Attack” (TIA) by Abushora et al. raises several questions in our daily clinical evaluation of patients with stroke, and also divers with unexplained Type II decompression sickness (DCS). A cohort of patients (stroke group) with either nonhemorrhagic stroke (CVA) or TIA (n = 321...

BACKGROUND Coronary artery hemostasis during offpump coronary artery bypass (OPCAB) may be achieved with extraluminal coronary occlusion or intraluminal coronary shunting. We sought to determine with a normal porcine beating-heart model whether coronary shunting preserves regional myocardial perfusion and function compared with coronary occlusion. METHODS Six pigs (50-60 kg) underwent sternot...

Gamma oscillations of the local field potential are organized by collective dynamics of numerous neurons and have many functional roles in cognition and/or attention. To mathematically and physiologically analyse relationships between individual inhibitory neurons and macroscopic oscillations, we derive a modification of the theta model, which possesses voltage-dependent dynamics with appropria...

BACKGROUND AND AIM Congenital portosystemic veno-venous malformations are rare abnomalities that often remain undiagnosed. Typically they are classified by their anatomical characteristics according to Morgan (extrahepatic, Abernethy malformations type Ia,b and II) and Park (intrahepatic, types 1-4). However, their clinical presentation is less dependent on the anatomical type. METHOD We revi...

THE TITLE of this paper is a crude translation, such as a simple machine might prepare, of the title of a Russian paper, Автоматический Перевод. То understand why the machine translation of languages has grown to be the subject, not of science-fiction tales, but of serious scientific investigation, some understanding of the operating principles of the type of machine under consideration is esse...

We consider the rail car management at industrial in-plant railroads. Demands for loaded or empty cars are characterized by a track, a car type, and the desired quantity. If available, we assign cars from the stock, possibly substituting types, otherwise we rent additional cars. Transportation requests are fulfilled as a short sequence of pieces of work, the so-called blocks. Their design at a ...

This paper describes how to extend the garbage collection for WAM [ACHS88] so that it will shunt chains of bound variables if possible. Doing so has two advantages: 1. Space is saved by making it possible to deallocate the intermediate cells. This is particularly useful when those cells are associated with frozen goals. 2. Later dereferencing is speeded up by not having to follow long variable ...

We describe the interdisciplinary management of a 34-year-old woman with dilated cardiomyopathy three months postpartum on a cardiac biventricular assist device (BVAD) as bridge to heart transplantation with delayed onset of intracardial shunting and subsequent hypoxemia due to massive pulmonary embolism. After emergency surgical embolectomy pulmonary function was highly compromised (PaO2/FiO2 ...

Shunting is a mechanism that permits translational initiation at internal codons positioned in proximity to a ribosome acceptor sequence. Sendai virus exploits shunting to express a series of proteins that initiate at the fourth and fifth start sites on the P/C mRNA (namely, the Y1 and Y2 proteins, respectively). Shunt-mediated initiation at these sites is codon independent. In an attempt to ch...
