۴۲٬۶۹۵ نتیجهPhi-square Lexical Competition Database (Phi-Lex): an online tool for quantifying auditory and visual lexical competition.
A widely agreed-upon feature of spoken word recognition is that multiple lexical candidates in memory are simultaneously activated in parallel when a listener hears a word, and that those candidates compete for recognition (Luce, Goldinger, Auer, & Vitevitch, Perception 62:615-62
Immunocytochemical demonstration of PHI and its co-existence with VIP in intestinal nerves of the rat and pig.
Immunocytochemical studies of the rat and pig indicate that immunoreactivity for PHI (heptacosapeptide recently isolated by TATEMOTO and MUTT, 1981, from the porcine intestine) is located in numerous nerve fibers in the ileum and colon. Myenteric and submucosal plexuses contain a
phi X174 genome-capsid interactions influence the biophysical properties of the virion: evidence for a scaffolding-like function for the genome during the final stages of morphogenesis.
During the final stages of phi X174 morphogenesis, there is an 8.5-A radial collapse of coat proteins around the packaged genome, which is tethered to the capsid's inner surface by the DNA-binding protein. Two approaches were taken to determine whether protein-DNA interactions af
Large scale system evaluations using PHY abstraction for LTE with OpenAirInterface
In this paper we present the complete methodology of expected effective SINR mapping (EESM) and mutual information effective SINR mapping (MIESM) based PHY abstraction for OpenAirInterface (OAI) LTE platform. The methodology consists of calibration of the ESM techniques using OAI
Cyclic AMP formation in chicken brain: effect of vasoactive intestinal peptide, peptide histidine-isoleucine (PHI), and some PHI-related peptides.
Vasoactive intestinal peptide (chicken form; chVIP), peptide histidine-isoleucine (porcine and rat forms; pPHI and rPHI), D-Phe(4) derivative of porcine PHI (D-Phe(4)-pPHI), peptide histidine-methionine (PHM; human PHI), and helodermin, were tested for their ability to stimulate
Optimal PHY and MAC Protocols for Wide-band Ad-hoc Networks
We consider a wide-band ad-hoc network with coherent radios in a slow-fading environment, and we analyze the performance of different physical layer (PHY) and medium access (MAC) schemes in such a network. Most of the existing analysis assume that PHY is based on a nearest neighb
The Escherichia coli FKBP-type PPIase SlyD is required for the stabilization of the E lysis protein of bacteriophage phi X174.
Most bacteriophages abruptly terminate their vegetative cycle by causing lysis of the host cell. The ssDNA phage phi X174 uses a single lysis gene, E, encoding a 91-amino-acid membrane protein that causes lysis of Escherichia coli by inhibiting MraY, a conserved enzyme of murein
PHY modulation/rate control for fountain codes in 802.11a/g WLANs
In this paper we consider the joint performance of fountain codes and 802.11a/g PHY modulation/coding. We consider optimality both in terms of maximizing goodput and minimizing energy, and results are presented for both theoretical and experimental channel models. In contrast to
Throughput Estimates for A-MPDU and Block ACK Schemes Using HT-PHY Layer
IEEE 802.11n standard has introduced the new schemes in MAC and HT-PHY layers to improve network throughput. The new schemes in MAC layer are A-MSDU, A-MPDU and Block ACK. In the HT-PHY layer there are MIMO transmission using up to 4 spatial streams, 40 MHz bandwidth channel and
Initial PHY Layer Proposal for Sub 11 GHz BWA Systems
This document provides an initial PHY system proposal of a low frequency (Sub 11 GHz) wireless access PHY for point-to-multipoint voice, video and data applications. The submission is for consideration of the Task Group to develop a PHY standard for BWA system. Purpose This contr
