The dynamic clamp comes of age.

Single electrode dynamic clamp with StdpC

Dynamic clamp is a powerful approach for electrophysiological investigations allowing researchers to introduce artificial electrical components into target neurons to simulate ionic conductances, chemical or electrotonic inputs or connections to other cells. Due to the rapidly changing and potentially large current injections during dynamic clamp, problematic voltage artifacts appear on the ele...

A Dynamic Clamp on Every Rig

The dynamic clamp should be a standard part of every cellular electrophysiologist's toolbox. That it is not, even 25 years after its introduction, comes down to three issues: money, the disruption that adding dynamic clamp to an existing electrophysiology rig entails, and the technical prowess required of experimenters. These have been valid and limiting issues in the past, but no longer. Techn...

مقایسه بین عوارض اعمال جراحی عروق با و بدون اندازه‌گیری aPTT و خنثی‌سازی هپارین با پروتامین

Background & Aim: clamp and also blood stasis during vascular surgeries. Heparin is administered to prevent thrombosis, and aPTT (activatedPartial Thromboplastin Time) test is used to make sure of anticoagulative effect of heparin. At the end of the operation,heparin is neutralized by protamin sulfate in some centers. In this study we assessed the necessity of aPTT and usingprotamin during vasc...

High Gain DC-DC Converter using Active Clamp Circuit (RESEARCH NOTE)

In this paper, a boost converter with a clamp circuit is proposed for high intensity discharge (HID) lamp application. The clamp circuit provides zero voltage turn on for both main and clamp switches. Compared to conventional boost converters, the proposed converter has the following advantages: (i) high voltage gain without suffering from extreme duty ratio, (ii) low stress on the switches and...
