همگام با سرعت در حال رشد خلاقیت و نوآوری های آموزش زبان به ویژه ظهور روش ارتباطی آموزش زبان? بسیاری از مدارس زبان با بازاندیشی آموزش و پرورش خود? برای گنجاندن فعالیت های ارتباطی، وزمینه ی شخصی سازی شده به شیوه های سنتی خود به روز رسانی شده اند. با این حال، مدارس ایرانی در این زمینه آهسته پیش رفته اند. از این رو، هدف عمده ی پژوهش حاضر برداشتن یک گام در پر کردن شکاف بین نظریه های آموزشی نو ظهور و...

Finite Element Analysis of Tissue Conductivity during High-frequency and Low-voltage Irreversible Electroporation

Introduction: Irreversible electroporation (IRE) is a process in which the membrane of the cancer cells are irreversibly damaged with the use of high-intensity electric pulses, which in turn leads to cell death. The IRE is a non-thermal way to ablate the cancer cells. This process relies on the distribution of the electric field, which affects the pulse amplitude, width, and electrical conducti...

Differentiation of Low- and High-Grade Gliomas Using High b-Value Diffusion Imaging with a Non-Gaussian Diffusion Model.

BACKGROUND AND PURPOSE Imaging-based tumor grading is highly desirable but faces challenges in sensitivity, specificity, and diagnostic accuracy. A recently proposed diffusion imaging method by using a fractional order calculus model offers a set of new parameters to probe not only the diffusion process itself but also intravoxel tissue structures, providing new opportunities for noninvasive tu...

Multi-component decaying behavior on high-b-value diffusion-weighted MRI

This study reported the multi-component decaying behavior on high-b-value diffusion-weighted MR images. Signal intensity was measured in different regions of the brain. Results showed that gray matter and cerebrospinal fluid exhibited single exponential decaying characteristics while multi-component decaying behavior was observed in some white matter areas with complicated neural fiber orientat...
