Imaging distributed and massed repetitions of natural scenes: spontaneous retrieval and maintenance.
Repetitions that are distributed (spaced) across time prompt enhancement of a memory-related event-related potential, compared to when repetitions are massed (contiguous). Here, we used fMRI to investigate neural enhancement and suppression effects during free viewing of natural scenes that were either novel or repeated four times with massed or distributed repetitions. Distributed repetition w...
متن کاملMassed and distributed repetition of natural scenes: Brain potentials and oscillatory activity.
Neural measures of repetition can result in either repetition suppression or enhancement effects, with enhancement sometimes interpreted as indicating episodic retrieval, rather than stimulus habituation. Here, we manipulated whether repetitions were massed (consecutive) or distributed (intermixed) and measured event-related potentials and oscillatory activity, investigating the question of whe...
متن کاملExplicit and spontaneous retrieval of emotional scenes: electrophysiological correlates.
When event-related potentials (ERP) are measured during a recognition task, items that have previously been presented typically elicit a larger late (400-800 ms) positive potential than new items. Recent data, however, suggest that emotional, but not neutral, pictures show ERP evidence of spontaneous retrieval when presented in a free-viewing task (Ferrari, Bradley, Codispoti, Karlsson, & Lang,...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
High Dynamic Range Imaging of Natural Scenes
The ability to capture and render high dynamic range scenes limits the quality of current consumer and professional digital cameras. The absence of a well-calibrated high dynamic range color image database of natural scenes is an impediment to developing such rendering algorithms for digital photography. This paper describes our efforts to create such a database. First, we discuss how the image...
