طیف گامای آنی تولید شده حین تابش پروتون به بافت، برای آنالیز عنصری بافت تحت درمان کار گرفته می‌­شود. هدف اصلی این در پروتون­درمانی ردیابی غلظت اکسیژن تومور است. پایش برخط تغییر عنصر پزشک را سمت ارزیابی روند بهبود و تخمین پاسخ بدن بیمار هدایت می‌­کند. مطالعه گاما یک فانتوم چشم انسان آشکارساز HPGe با استفاده از ابزار Geant4 شبیه‌سازی ­کارگیری شبکه عصبی انجام شد. 33 نمونه حاوی تومورهای متفاوت نظر ...

Distributed real-time control applications consist of sets of tasks that interact with the physical world through sensors and actuators and are executed on a dispersed set of locations that are interconnected by a communication subsystem. Timeliness and safety requirements of the application demand deterministic execution of tasks and predictive communication. Deterministic and predictable syst...

The temporal difference limen (TDL) can be measured with noninvasive electrical ear canal stimulation. The objective of the study wa to determine the role of preoperative TDL measurements in predicting patients' speech perception after cochlear implantation. We carried out a retrospective chart analysis of fifty-four cochlear implant (CI) patients with preoperative TDL and postoperative bisylla...

When thoracic duct lymphocytes (TDL) from mice given sheep erythrocytes (SRC) 1 day previously (1-day-primed TDL) were placed in microcultures with antigen for 5-6 days, the cells failed to produce antibody to SRC, but responded well to horse erythrocytes (HRC); reciprocal results were obtained with TDL from HRC-injected mice. The specific unresponsiveness of the TDL was observed despite the pr...

Uniform linear array (ULA)-based tapped-delay line (TDL) structure has good performance metrics when the signal sources are located at the middle angles. It offers poor performance when the signal sources are close to the array endfire. In this paper, a new approach is proposed which offers higher performance and desired beamforming on TDL structure when the wideband uncorrelated radio sources ...

In this paper, we present a Link-16-based tactical data link (TDL) simulator with cognitive antijamming capability (CAJC). CAJC improves antijamming capability of existing TDL by adding the cognitive radio (CR) spectrum sensing-based jammer detection. In the presented TDL, each terminal that senses (or detects) the jammer signal can avoid the jammer spectrum opportunistically. For jammer signal...

To investigate the clonal relationship between follicular lymphoma (FL) and transformed diffuse lymphoma (tDL), we examined the expression of tumor idiotype, immunoglobulin (Ig) gene rearrangements and sequence of Ig variable genes in paired tissue specimens. All 16 cases analyzed expressed surface immunoglobulin (sIg) on both the FL and the tDL, though the immunophenotype of one case of FL cou...
