The eye movements elicited by auditory stimuli--the audio-ocular response (AOR)--differ from those made in response to a visual target. The movements consist of both monosaccadic and multiple saccadic refixations (MSR). In visual refixation, monosaccadic refixations are always accurate; in AOR, they rarely are. In MSR, many strategies were used in the attempt to find the target but they were no...
Atomic force microscopy (AFM) was used in concert with transmission electron microscopy (TEM) to image magnetotactic bacteria (Magnetospirillum gryphiswaldense MSR-1 and Magnetospirillum magneticum AMB-1), magnetosomes, and purified Mms6 proteins. Mms6 is a protein that is associated with magnetosomes in M. magneticum AMB-1 and is believed to control the synthesis of magnetite (Fe(3)O(4)) withi...
Based on a stochastic geometry framework, we establish an analysis of the multi-hop spatial reuse aloha protocol (MSR-Aloha) in ad hoc networks. We compare MSR-Aloha to a simple routing strategy, where a node selects the next relay of the treated packet as to be its nearest receiver with a forward progress toward the final destination (NFP). In addition, performance gains achieved by employing ...
تصویربرداری مایکروویو توسط بسیاری از محققین مورد توجه قرار گرفته و در طول چند دهه اخیر توسعه داده شده است. تصویربرداری مایکروویو یک مساله پراکندگی معکوس بوده و روشهایی که برای حل مسائل پراکندگی معکوس به کار می روند را می توان به دو دسته کلی روش های خطی و غیرخطی تقسیم نمود. روشهای پراکندگی معکوس غیرخطی، قادر به بازسازی کمی اهداف می باشند ولی به علت محاسبات زیاد، کاربرد آنها در سیستم های عملی با ...
در این پژوهش سنتز ترکیب Ti3SiC2 با ساختار فازی MAX توسط آسیاکاری پودرهای اولیه Ti، Si و C مورد بررسی قرار گرفت. بدین منظور مخلوط پودری تیتانیوم، سیلیسیوم و گرافیت با نسبتهای استوکیومتری مطابق با ترکیب شیمیایی Ti3SiC2، به صورت 3:1:2 توسط آسیای سیارهای پر انرژی با نسبت گلوله به پودر 10 به 1 و سرعت 450 دور بر دقیقه، از صفر تا 20 ساعت مورد آسیاکاری قرار گرفت. جهت شناسایی فازی محصولات آسیاکاری د...
The shielding performance of a magnetically shielded room (MSR) for bio-magnetic measurement was evaluated using JEITA standard (EM-4502 and EM-4503). In the process evaluation, some problems were extracted, such as fact that MSR shape not covered by standard. Therefore, authors revised EM-4502 EM-4503. main points revision are expansion target reexamination placement conditions accuracy exciti...
Maritime search and rescue (MSRIn the maritime publications, the abbreviation for search and rescue is also SAR. Here we use MSR to distinguish it from the abbreviation for Synthetic Aperture Radar.) became an enormous task with the vast growth of marine transportation and other marine activities. In the year of 2006, the MSR centers and maritime authorities in China organized and coordinated 1...
The epidemiologic relatedness of 29 erythromycin-resistant Gemella sp. strains from normal flora, characterized previously, were evaluated by pulsed-field gel electrophoresis (PFGE). Three isolates carried the tet(O) gene and the tet(M) gene. The msr(A) gene was found in two Gemella morbillorum strains in combination with the erm(B) or mef(E) gene. The sequences of the mef(A/E), erm(B), and msr...

Clustered distributed storage models real data centers where intraand cross-cluster repair bandwidths are different. In this paper, exact-repair minimum-storage-regenerating (MSR) codes achieving capacity of clustered distributed storage are designed. Focus is given on two cases: = 0 and = 1/(n−k), where is the ratio of the available crossand intra-cluster repair bandwidths, n is the total numb...
