BACKGROUND/AIMS It has been recently reported that celiac ganglia can be identified by linear-array endoscopic ultrasonography (EUS). Still, there has been no report on the detection rate of celiac ganglia with radial scanning EUS. The aim of this study was to evaluate the detection rate of celiac ganglia by radial scanning echoendoscopy during a routine examination. METHODS We prospectively ...
Limabeam is an approach to multi-microphone array processing for ASR which makes minimal assumptions about system geometry, instead searching for filters to maximise output likelihoods under a speech model. The first results of Limabeam on the AMI meeting corpus are given, then two extensions of the algorithm for this corpus. First, it is shown that the original local gradient following sticks ...
We present designs for Ioffe-Pritchard type magnetic traps using planar patterns of hard magnetic material. Two designs are based on 40 μm foil of FePt. The first sample yields calculated axial and radial trap frequencies of 51 Hz and 6.8 kHz, respectively. For the second sample the calculated frequencies are 34 Hz and 11 kHz. The structures were produced by spark erosion and used successfully ...
We present interferometric observations of the σ Orionis triple system using the CHARA Array, NPOI, and VLTI. Using these measurements, we spatially resolve the orbit of the close spectroscopic binary (Aa,Ab) for the first time and present a revised orbit for the wide pair (A,B). Combining the visual orbits with previously published radial velocity measurements and new radial velocities measure...
فرض کنیم $r$ حلقه ای جابجایی و یکدار، $a$ و $b$ جبر های یکدار بر روی $r$ و $m$ یک $(a,b)$- دو مدول باشد که $m$ به عنوان یک $a$- مدول چپ وفادار و $b$- مدول راست وفادار است. فرض کنیم $left[ {egin{array}{*{20}c} a & m 0 & b end{array}} ight]$ $mathcal{t}=$ جبر مثلثی شامل $a$، $b$ و $m$ است در این جا مشت...
We present new results based on high-resolution observations of Sgr A West at the Galactic center with the Very Large Array (VLA) at 1.3 cm. By combining recent observations with those made at earlier epochs with the VLA at wavelengths of 1.3 and 3.6 cm, we measured proper motions for 71 compact HII components in the central 80 (3 pc, assuming D = 8 pc). Using VLA archival data for the H92α rad...

Interphase microtubules are organized into a radial array with centrosome in the center. This organization is a subject of cellular regulation that can be driven by protein phosphorylation. Only few protein kinases that regulate microtubule array in interphase cells have been described. Ste20-like protein kinase LOSK (SLK) was identified as a microtubule and centrosome-associated protein. In th...
