The potential of multiantenna interference cancellation receiver algorithms for increasing the uplink throughput inWLAN systems such as 802.11 is investigated. The medium access control (MAC) in such systems is based on carrier sensing multiple-access with collision avoidance (CSMA/CA), which itself is a powerful tool for the mitigation of intrasystem interference. However, due to the spatial d...

Neurons in the central nucleus of the inferior colliculus (IC) receive excitatory and inhibitory inputs from both lower and higher auditory nuclei. Interaction of these two opposing inputs shapes response properties of IC neurons. In this study, we examine the interaction of excitation and inhibition on the responses of two simultaneously recorded IC neurons using a probe and a masker under for...

Ptolemy is a flexible and extensible platform for simulations, rapid prototyping, and other software systems. It is our third generation software environment, building on our experience with Blosim, a signal processing simulation system, and Gabriel, a prototyping environment for real-time signal processing. Unlike its predecessors, Ptolemy does not enforce a single simulation or execution mode...

Electromagnetic compatibility (EMC) analysis of high-speed circuits is mandatory due to the rapid increase in operating frequencies, RF interference and PCB layout density. Radiated emission and immunity tests of electronic circuits and ICs are an important part of the overall EMC analysis and they have become a growing concern in prediction of an electronic system reliability. These tests are ...

This paper aims to explore RLC equivalent circuit synthesis method for reduced-order models of interconnect circuits obtained by Krylov subspace based model order reduction (MOR) methods. To guarantee pure RLC equivalent circuits can be synthesized, both the structures of input and output incidence matrices and the block structure of the circuit matrices should be preserved in the reduced-order...

To achieve continuous size, weight and cost reductions, wireless handset manufacturers and their semiconductor suppliers have been developing new semiconductor devices and packaging technologies that enable high levels of functional integration at the smallest most cost effective level, which is through silicon (Si) integration. The high levels of Si integration for baseband functions have come...

Structure of Oligostatin C Oligostatin C (Ic), a basic, water-soluble, amorphous substance; m.p. 183'C (dec.), [a]21+154' (c 1, H,O), shows strong IR absorption maxima at 31003600 and 9801180 cm-1 indicative of its oligosaccharide nature. PMR spectrum of Ic in D2O shows a methyl signal at 1.38 ppm (d, J=6 Hz), a methine proton at 2.76 ppm (t, J=9 Hz) and complex signals at 5.2 5.5 ppm assignabl...

Latchup failure which occurred at only one output pin of a power controller IC product is investigated in this work. The special design requirement of the internal circuits causes the parasitic diode that is inherent between the n-well and p-substrate to be a triggering source of the latchup occurrence in this IC. The parasitic diode of the internal PMOS was easily turned on by an anomalous ext...

Singer et al. recently published the results of long-awaited TICACOS-International randomized controlled trial (RCT), which found no benefit indirect calorimetry (IC)-guided feeding in mixed intensive care unit (ICU) patients, as compared to up a calculated energy target [ [1] P. De Waele E. Sanchez C. Ruiz Santana S. Montejo J.C. Laterre P.F. TICACOS international: multi-center, randomized, pr...
