During the development, tight regulation of the expansion of neural progenitor cells (NPCs) and their differentiation into neurons is crucial for normal cortical formation and function. In this study, we demonstrate that microRNA (miR)-128 regulates the proliferation and differentiation of NPCs by repressing pericentriolar material 1 (PCM1). Specifically, overexpression of miR-128 reduced NPC p...

In this paper, we discuss the development of very sensitive very long wavelength infrared (VWIR) GaAs/AIXGal.XAs quantum well infrared photodetectors (QWIPS), fabrication of random reflectors for efficient light coupling, and the demonstration of a V WIR 128 x 128 focal plane array imaging camera. Excellent imagery, with a noise equivalent differential temperature (NEAT) of 30 mK has been achie...

* --This paper presents a new generation 128x128 Focal Plane Analog Programmable Array Processor (FPAPAP), from a system level perspective. The design has recently sent to fabrication in a 0.35μm standard digital 1P-5M CMOS Technology. The chip has been designed to achieve the high-speed and moderate-accuracy constraints of most real time image processing applications. It has been designed to b...

A novel circuit switched swizzle network called XRAM is presented. XRAM uses an SRAM-based approach producing a compact footprint that scales well with network dimensions while supporting all permutations and multicasts. Capable of storing multiple shuffle configurations and aided by a novel sense-amp for robust bit-line evaluation, a 128×128 XRAM fabricated in 65nm achieves a bandwidth exceedi...

This paper describes a 128 128 pixel CMOS vision sensor. Each pixel independently and in continuous time quantizes local relative intensity changes to generate spike events. These events appear at the output of the sensor as an asynchronous stream of digital pixel addresses. These address-events signify scene reflectance change and have sub-millisecond timing precision. The output data rate dep...
