Cellular origins and genetic factors governing the genesis and maintenance of glioblastomas (GBM) are not well understood. Here, we report a pathogenetic role of the developmental regulator Id4 (inhibitor of differentiation 4) in GBM. In primary murine Ink4a/Arf(-/-) astrocytes, and human glioma cells, we provide evidence that enforced Id4 can drive malignant transformation by stimulating incre...
in direct torque control, the selection of an applied voltage vector is based on the measuredparameters at the beginning of the sampling period. the delay between the measurement and the application of the voltage vector is the origin of an extra torque ripple. in this paper, a new predictive controller is proposed for compensating this delay and reducing the torque ripple. the stator current i...
Sarah Bowen and Sara Kreindler argue that indicators can be valuable, but are also often flawed. They suggest that performance indicators should at best serve as a flag for policy makers but should not drive decisions. We would argue that there is growing evidence of the positive impact of performance indicators. When performance indicators are selected based on sound strategies - and used as p...
در این پروژه به تشریح روشی برای آشکارسازی کاملاً خودکار عروق شبکیه چشم پرداخته شده است. ابزارهای مهمی که روش مذکور از آنها بهره می گیرد عبارتند از تقسیم بندی تصویر و تبدیل رادون محلی. نحوه کار بدین صورت است که ابتدا تصویر شبکیه چشم به پنجره هایی با ابعاد از پیش تعیین شده که دارای همپوشانی در هر دو راستای افقی و عمودی هستند، تقسیم بندی شده و سپس تبدیل رادون به هر یک از پنجره ها اعمال می شود. پیک ...
Neuroimaging studies have produced seemingly contradictory findings in regards to the pathophysiology of insomnia. Although most study results are interpreted from the perspective of a "hyperarousal" model, the aggregate findings from neuroimaging studies suggest a more complex model is needed. We provide a review of the major findings from neuroimaging studies, then discuss them in relation to...
