We present a two-dimensional (2D) snapshot multispectral imager that utilizes the optical transmission characteristics of nanohole arrays (NHAs) in a gold film to resolve a mixture of input colors into multiple spectral bands. The multispectral device consists of blocks of NHAs, wherein each NHA has a unique periodicity that results in transmission resonances and minima in the visible and near-...

The aim of this work is to present a new technique for defining interconnected sub-populations of cultured neurons on microelectrode arrays (MEAs). An automated microdrop delivery technique allows to design and realize spatially distributed neuronal ensembles by depositing sub-nanoliter volumes of adhesion molecules in which neurons grow and develop. Electrophysiological tests demonstrate that ...

avicenna has divided the conditionals to the real cogent (i.e. with possible antecedent) and the verbal cogent (i.e. with the impossible antecedent). denying the truth of the latter, he caused controversies among moslem logicians. at the paper, we report the controversies, analyze the real and verbal cogent conditionals, formalize them in modern modal and relevant logics, and finally, defend id...

This document reports work undertaken at NPAC, Syracuse under the DOE Global Array Extension Project. This work was intended to investigate the feasibility of interfacing, and perhaps eventually integrating , GA, ARMCI and the Parallel Compiler Runtime Consortium library, Adlib. In particular, we have reimplented parts of the Adlib library in terms of ARMCI, and also produced a version of GA wh...

The effect of magnetospheric substorms on the global ionospheric convection pattern is widely debated. Discussed here, is a study made of ionospheric electric currents, co-incident with plasma convection at the time of substorm onset, using the HF radars of the Super Dual Auroral Radar Network (SuperDARN), and the global array of ground magnetometers. Preliminary results are presented, which ut...

Protein arrays are frequently used to profile antibody repertoires in humans and animals. High-throughput protein array characterisation of complex antibody repertoires necessitates the use of extensively validated secondary detection antibodies. This article details the validation of an affinity-isolated anti-chicken IgY antibody produced in rabbit and a goat anti-rabbit IgG antibody conjugate...

Efficient spike acquisition techniques are needed to bridge the divide from creating large multielectrode arrays (MEA) to achieving whole-cortex electrophysiology. In this paper, we introduce generalized analog thresholding (gAT), which achieves millisecond temporal resolution with sampling rates as low as 10 Hz. Consider the torrent of data from a single 1,000-channel MEA, which would generate...
