Objective: It is generally admitted that the endocrine cell organization in human islets is different from that of rodent islets. However, a clear description of human islet architecture has not yet been reported. The aim of this work was to describe our observations on the arrangement of human islet cells.
Research design and methods: Human pancreas specimens and isolated islets were processed for histology. Sections were analyzed by fluorescence microscopy after immunostaining for islet hormones and endothelial cells.
Results: In small human islets (40-60 mum in diameter), beta-cells had a core position, alpha-cells had a mantle position, and vessels laid at their periphery. In bigger islets, alpha-cells had a similar mantle position but were found also along vessels that penetrate and branch inside the islets. As a consequence of this organization, the ratio of beta-cells to alpha-cells was constantly higher in the core than in the mantle part of the islets, and decreased with increasing islet diameter. This core-mantle segregation of islet cells was also observed in type 2 diabetic donors but not in cultured isolated islets. Three-dimensional analysis revealed that islet cells were in fact organized into trilaminar epithelial plates, folded with different degrees of complexity and bordered by vessels on both sides. In epithelial plates, most beta-cells were located in a central position but frequently showed cytoplasmic extensions between outlying non-beta-cells.
Conclusions: Human islets have a unique architecture allowing all endocrine cells to be adjacent to blood vessels and favoring heterologous contacts between beta- and alpha-cells, while permitting homologous contacts between beta-cells.
The Music Division holds thousands of arrangements which could be considered "big-band arrangements." The following list is a sample of the material we have. All the arrangements listed here meet three criteria: 1) they consist of a full set of parts; 2) they were published in the United States; 3) they come from the years 1935-1955.
They also meet one or more of three additional criteria: A) they bear the name of a well-known band or soloist; B) the arrangement is by a well-known arranger; or C) the arrangement is of a well-known song or a song which we thought would be of particular interest to some of those seeking big-band parts.
Among works meeting these criteria we have tried for a varied sample of our holdings, rather than for a list of "most famous arrangements," "best arrangements," or "rarities from the Library of Congress." All of these arrangements are, so far as we know, protected by copyright.

Arrangement and description lie at the very heart of the archival endeavor. While all archival functions are crucial and interdependent, arrangement and description transform the potential value of materials into practical, usable value for researchers and others. In Arranging and Describing Archives and Manuscripts, Dennis Meissner provides a solid foundation in the history, theory, and standards supporting arrangement and description. In addition, he clearly demonstrates the approaches, methods, and mechanics required to process archival collections.
The processing landscape has changed considerably in the last decade: archivists focus more on the economics of processing, descriptive standards have matured and increased in number, new technologies and viewpoints have challenged long-standing assumptions, and evolving systems and software have changed the mechanics of metadata capture and serialization and our approaches to those fundamental processes. This is a must-read book for every archivist practicing today.
Neurons in the medial superior olive (MSO) detect 10 microsecond differences in the arrival times of a sound at the two ears. Such acuity requires exquisitely precise integration of binaural synaptic inputs. There is substantial understanding of how neuronal phase locking of afferent MSO structures, and MSO membrane biophysics subserve such high precision. However, we still lack insight into how the entirety of excitatory inputs is integrated along the MSO dendrite under sound stimulation. To understand how the dendrite integrates excitatory inputs as a whole, we combined anatomical quantifications of the afferent innervation in gerbils of both sexes with computational modeling of a single cell. We present anatomical data from confocal and transmission electron microscopy showing that single afferent fibers follow a single dendrite mostly up to the soma and contact it at multiple (median 4) synaptic sites, each containing multiple independent active zones (the overall density of active zones is estimated as 1.375 per μm2). Thus, any presynaptic action potential may elicit temporally highly coordinated synaptic vesicle release at tens of active zones, thereby achieving secure transmission. Computer simulations suggest that such an anatomical arrangement boosts the amplitude and sharpens the time course of excitatory postsynaptic potentials by reducing current sinks and more efficiently recruiting subthreshold potassium channels. Both effects improve binaural coincidence detection as compared to single large synapses at the soma. Our anatomical data further allows for estimation of a lower bound of 7 and an upper bound of 70 excitatory fibers per dendrite.
N2 - The fourth movement explores the temporal relationship between arrangements and re-arrangements, addressing the question of how an obdurate and 'sticky' temporal order may give way to palpable re-arrangement of the ways in which subjects experience time. Eschewing a concern with linear homogenous time, it addresses the processes of re-arrangement by understanding the dynamics of grave events, hauntings of the past, subtly changing rhythms of everyday life, and the force of potential futures in synchrony.

N2 - The main functions of automated systems rely on advanced sensors for the detection and perception of the environment around the vehicle. Radars and cameras are commonly utilized to detect potential obstacles and vehicles ahead on the road. Nevertheless, cameras can generate spurious detections in extreme weather conditions, such as fog, rain, dust, snow, dark, and heavy sunlight in the sky. Due to limitations in the vertical field view of the radars, single radars are not reliable to detect the height of the targets precisely. In this paper, an innovative triple radar arrangement (long-range, medium-range, and short-range radars) with a sensor fusion technique is proposed to detect objects of different sizes in the level 2 Advanced Driver-Assistance (ADAS) system. The typical objects including trucks, pedestrians, and animals are detected in different scenarios. The developed model considered ISO 26262 and ISO/PAS 21448 to reasonably address insufficient robustness and the inability of the sensors. The models of sensor and level 2 ADAS systems are developed using MATLAB toolbox and Simulink. Sensor detection performance is determined by running simulations with a triple radar setup. Obtained results demonstrate that the proposed approach generates accurate detections of targets in all tested scenarios.
