We develop the major steps taken to map a realistic spike timing-dependent plasticity (STDP) model into digital hardware architecture. Several types of mappings are implemented and tested on FPGA device. We compare their applicability to a real-time spiking neural network (SNN) simulator running in biological time-scale. Keywords—Spiking neural network, STDP, realistic models, real-time process...

The cerebellum-red nucleus-facial motoneuron (Mn) pathway has been reported as being involved in the proper timing of classically conditioned eyelid responses. This special type of associative learning serves as a model of event timing for studying the role of the cerebellum in dynamic motor control. Here, we have re-analyzed the firing activities of cerebellar posterior interpositus (IP) neuro...

We present a case of incessant wide-complex tachycardia in a patient with left-ventricular assist device, and discuss the differential diagnosis with an in-depth analysis of the intracardiac tracings during the invasive electrophysiologic study, including interpretation of the relative timing of the fascicular signals during tachycardia and in sinus rhythm, and interpretation of pacing and entr...

A new methodology to accurately simulate the Photon Detection Efficiency and Jitter tail of SPAD devices is presented. This method first relies on use electric field lines mimic carriers’ trajectories. model for impact ionization avalanche probability then used obtained avalanche, coupled with optical absorption, PDE extracted. Finally, an advection–diffusion drift diffusion carriers within dev...

We report a 65-year-old man with fulminant myocarditis undergoing percutaneous cardiopulmonary support (PCPS) and left ventricular assist device (LVAD). PCPS and intra-aortic balloon pumping was initially introduced for cardiogenic shock in the emergency department. We switched to LVAD because cardiac function did not recover despite PCPS for 5 days. Cardiac function then gradually improved, an...

Shortage of donors enhances harvesting of borderline hearts. When such organs fail, a ventricular assist device may salvage the patient waiting for either recovery or for retransplantation. We describe a series of 12 patients who required circulatory support following orthotopic heart transplantation, with the use of four different devices. Four patients survived. The aim of this study is to de...

Solid state thermal neutron detectors are desirable for replacing the current He based technology, which has some limitations arising from stability, sensitivity to microphonics and the recent shortage of He. Our approach to designing such solid state detectors is based on the combined use of high aspect ratio silicon PIN pillars surrounded by B, the neutron converter material. To date, our hig...

The HTML5 standard is wide-spread on mobile devices. In combination with the Web Audio API, it allows for massively distributed real-time audio rendering. But timing issues exist, mainly because of the lack of standard inter-device synchronisation. This paper proposes a synchronisation solution based on HTML5. Using a shared reference time, we achieved the distributed rendering of audio events ...

A method for predicting the performance of disk scheduling algorithms on real machines using only their performance on virtual machines is suggested. The method uses a dynamically loaded kernel intercept probe (iprobe) to adjust low-level virtual device timing to match that of a simple model derived from the real device. An example is provided in which the performance of a newly proposed disk s...
