Neuromodulation is often thought to have a static, gain-setting function in neural circuits. Here we report a counter example: the neuromodulatory effect of a serotonergic neuron is dependent on the interval between its spikes and those of the neuron being modulated. The serotonergic dorsal swim interneurons (DSIs) are members of the escape swim central pattern generator (CPG) in the mollusk Tr...

انبارداری متقاطع یک سیستم توزیع است که در آن کالاها با هدف آماده‌سازی ظرفیت کامل ماشین‌‌‌های حمل و کاهش هزینه نگهداری موجودی از تأمین‌کنندگان به مقاصد تقاضا جابه­‌جا ‌‌می‌شوند. مسئله زمان‌بندی اخیراً توسط بسیاری پژوهشگران موردمطالعه قرار گرفته، اما عمده این مطالعات موارد شرایط قطعی بوده است؛ درحالی‌که عدم­‌قطعیت‌ها فرآیند وجود دارد. پژوهش حاضر، مرتبط عملیات انبار مرکز لجستیک (میدان مرکزی میوه تر...

Based on the modern spectrum estimation theory and wavelet packet analysis (WPA), a new method is proposed for suppressing discrete spectral interference (DSI) within partial discharge (PD) signal. Firstly, the frequencies of DSI are determined based on the FFT of measured signal. Then, a model of DSI could be assumed and its parameters, such as amplitude and phase can be calculated by using th...

The dynamic strength index (DSI), often calculated as the ratio of countermovement jump (CMJ) propulsion peak force to isometric mid-thigh pull (IMTP) peak force, is said to inform whether ballistic or maximal strength training is warranted for a given athlete. CMJ propulsion peak force is highly influenced by jump strategy, however, which is not highlighted by the DSI alone. This study aimed t...

In comparison with conventional diffusion tensor imaging (DTI) technique, diffusion spectrum imaging (DSI) allows for delineating crossing and touching fibers in the brain and has been explored in clinical and preclinical studies. Non-human primates (NHPs) resemble most aspects of human and are widely employed in various neuroscience researches and pharmaceutical development. In the present stu...
