Whole cell patch and cell-attached recordings were obtained from neurons in intact ganglia of the myenteric plexus of the guinea pig duodenum. Two classes of neuron were identified electrophysiologically: phasically firing AH neurons that had a pronounced slow afterhyperpolarization (AHP) and tonically firing S neurons that lacked a slow AHP. We investigated the properties of the slow AHP and t...

BACKGROUND Patient involvement is widely acknowledged to be a valuable component in health technology assessment (HTA) and healthcare decision making. However, quantitative approaches to ascertain patients' preferences for treatment endpoints are not yet established. The objective of this study is to introduce the analytic hierarchy process (AHP) as a preference elicitation method in HTA. Based...

The slow Ca2+-activated K+ current (sI(AHP)) plays a critical role in regulating neuronal excitability, but its modulation during abnormal bursting activity, as in epilepsy, is unknown. Because synaptic transmission is enhanced during epilepsy, we investigated the synaptically mediated regulation of the sI(AHP) and its control of neuronal excitability during epileptiform activity induced by 4-a...

Afterhyperpolarization (AHP) is a principal feedback mechanism in the control of the frequency and patterning of neuronal firing. In principal projection neurons of the olfactory bulb, the mitral cells (MCs), the AHP is produced by three separate components: classical potassium-mediated hyperpolarization, and the excitatory and inhibitory components, which are generated by the recurrent dendrod...

This paper presents a two-dimensional approximately harmonic projection (2DAHP) algorithm for gait recognition. 2DAHP is originated from the approximately harmonic projection (AHP), while 2DAHP offers some advantages over AHP. 1) 2DAHP can preserve the local geometrical structure and cluster structure of image data as AHP. 2) 2DAHP encodes images as matrices or second-order tensors rather than ...

یکی از مهم‌ترین مدهای حمل‌ونقل عمومی شبکة مترو است که تأثیر بسزایی در کاهش ترافیک و آلودگی هوا دارد. ازدیگرسو، با توجه به هزینه‌های سرسام‌آور راه‌اندازی مترو، توسعة مرحله‌به‌مرحله بهره‌برداری یک خط اجرای خطوط دیگر به‌دست مدیران شهری مورد است. بنابراین، هدف این تحقیق بررسی میزان دسترسی متروی اصفهان افق 1410، رویکرد عدالت مکانی، دو جنبة افقی عمودی پنج طبقة اجتماعی، استفاده شاخص‌های ضریب جینی، منح...
