AbstractThis paper first briefly reviews a few of the early studies that established some of the salient features of light-induced degradation in a-Si,Ge:H. In particular, I discuss the fact that both Si and Ge metastable dangling bonds are involved. I then review some of the recent studies carried out by members of my laboratory concerning the details of degradation in the low Ge fraction alloys utilizing the modulated photocurrent method to monitor the individual changes in the Si and Ge deep defects. By relating the metastable creation and annealing behavior of these two types of defects, new insights into the fundamental properties of metastable defects have been obtained for amorphous silicon materials in general. I will conclude with a brief discussion of the microscopic mechanisms that may be responsible.

AbstractSalient features of recombination at ARG4 of Saccharomyces provoke a variation of the double-strand-break repair (DSBR) model that has the following features: (1) Holliday junction cutting is biased in favor of strands upon which DNA synthesis occurred during formation of the joint molecule (this bias ensures that cutting both junctions of the joint-molecule intermediate arising during DSBR usually leads to crossing over); (2) cutting only one junction gives noncrossovers; and (3) repair of mismatches that are semirefractory to mismatch repair and/or far from the DSB site is directed primarily by junction resolution. The bias in junction resolution favors restoration of 4:4 segregation when such mismatches and the directing junction are on the same side of the DSB site. Studies at HIS4 confirmed the predicted influence of the bias in junction resolution on the conversion gradient, type of mismatch repair, and frequency of aberrant 5:3 segregation, as well as the predicted relationship between mismatch repair and crossing over.

Heavy eye syndrome is an important type of myopia-induced strabismus. We provide an overview of heavy eye syndrome, from its history to its most salient features. The theory of the orbital and rectus muscle pulley system as it relates to heavy eye syndrome and the prevailing theories on the pathophysiology of heavy eye syndrome in the current literature are discussed. We also highlight the presentation of heavy eye syndrome, its typical features on imaging, and differential diagnosis. Finally, we provide an overview on the management of heavy eye syndrome, including a description of several current surgical techniques.

AbstractAnimal agriculture predominantly involves farming social animals. At the same time, the nature of agriculture requires severely disrupting, eliminating, and controlling the relationships that matter to those animals, resulting in harm and unhappiness for them. These disruptions harm animals, both physically and psychologically. Stressed animals are also bad for farmers because stressed animals are less safe to handle, produce less, get sick more, and produce poorer quality meat. As a result, considerable efforts have gone into developing stress-reduction methods. Many of these attempt to replicate behaviours or physiological responses that develop or constitute bonding between animals. In other words, humans try to mitigate or ameliorate the damage done by preventing and undermining intraspecies relationships. In doing so, the wrong of relational harms is compounded by an instrumentalisation of trust and care. The techniques used are emblematic of the welfarist approach to animal ethics. Using the example of gentle touching in the farming of cows for beef and dairy, the paper highlights two types of wrong. First, a wrong done in the form of relational harms, and second, a wrong done by instrumentalising relationships of care and trust. Relational harms are done to nonhuman animals, whilst instrumentalisation of care and trust indicates an insensitivity to morally salient features of the situation and a potential character flaw in the agents that carry it out.

Strain Dependent

SummaryAn elegant design stratagem for an organ intended to carry loads for life without fracturing, rupturing or wearing out would make those loads determine the organ's strength. It seems load-bearing mammalian bones, joints, fascia, ligaments and tendons do exactly that. Physiologists begin to understand how they do it, and that led to the Utah paradigm of skeletal physiology. Those adaptations occur in two major steps. The first step creates the genetically predetermined newborn skeleton with its anatomical relationships and biologic machinery. The second step adds to the first one all postnatal adaptations to mechanical and other challenges that would affect an organ's strength, size, architecture and composition. During postnatal growth, increasing loads make tissue-level biologic mechanisms correspondingly increase the strength of such organs. Mechanical strain-dependent signals help to control that process, which muscle strength, muscle anatomy and neuromuscular physiology strongly influence. Its problems seem to cause or help to cause numerous skeletal and some extraskeletal disorders. A Table in the article lists examples of them.This article summarizes salient features of the Utah paradigm, which includes both facts and some meanings inferred from them. Other times and people must resolve any questions about those meanings and about the devils that can lie in the details. Parenthetically, instead of the accuracy of the facts on which that paradigm stands, the above questions usually concern the different meanings people can infer from facts, and whether particular facts and ideas would be relevant to a particular issue.

Prognostic Data

Numerical 500-mb prognostic data is now being transmitted on the Service C circuit. The procedure of transcribing this data on a map and then analyzing it in the conventional manner takes some 20 to 30 min. Lines indicating contour heights can be drawn on the teleprinter copy, and then an overlay map can be placed on the analyzed teleprinted copy to delineate the geographical areas on the teleprinter copy. Salient features of the map can be determined within 3 to 5 min by this procedure.

Planar Metamaterials

This paper is a critical review of metasurfaces, which are planar metamaterials. Metamaterials offer bespoke electromagnetic applications and novel properties which are not found in naturally occurring materials. However, owing to their 3D-nature and resonant characteristics, they suffer from manufacturing complexity, losses and are highly dispersive. The 2-dimensional nature of metasurfaces allows ease of fabrication and integration into devices. The phase discontinuity across the metasurface offers anomalous refraction, thereby conserving the good metamaterial properties while still offering the low-loss characteristics. The paper discusses salient features and applications of metasurfaces; wavefront shaping; phase jumps; non-linear metasurfaces; and their use as frequency selective surfaces (FSS).
