In this study, immune responses against Streptococcus iniae infections in rainbow trout (Oncorhynchus mykiss) were analyzed. Anti-streptococcal antibody (ASA) levels, respiratory burst activity (RBA), phagocytic activity (PA) and phagocytic index (P index) were measured in kidney macrophages. Fish were allocated to three experimental groups (n = 50 per group): survivors of natural S. iniae inf...
High-frequency burst neurons in the pons provide the eye velocity command (equivalently, the primary oculomotor drive) to the abducens nucleus for generation of the horizontal component of both head-restrained (HR) and head-unrestrained (HU) gaze shifts. We sought to characterize how gaze and its eye-in-head component differ when an "identical" oculomotor drive is used to produce HR and HU move...
A new class of burst-error-correcting codes and its application to PCM tape recording systems, Proof of Theorem 1. Let j 1 < j 2 < : : : < j s be a sequence consisting of all indexes 0 < j r h such that a j 6 = a j?1 ; note that j s = r h , and deene j s+1 = j s + 1. Fix T to a value less than or equal to r v. For every 1 ` s we have,
The influence of operating variables [viz: temperature 55-85°C, process time 30-120 min, pH 9-11,peraceticacid concentration 0.5-3.5% oven dried pulp (o.d.p.)., and sodium perborate concentration 1-5% o.d.p.] on the bleached pulp characteristics [viz: viscosity (VI), brightness (BR), kappa number (KN)], and resulting paper sheets properties [viz: breaking length (BL), stretch (ST), tear (TI), a...
We present observations of GRB 060124, the first event for which both the prompt and the afterglow emission could be observed simultaneously and in their entirety by the three Swift instruments. Indeed, Swift-BAT triggered on a precursor ∼ 570 s before the main burst peak, and this allowed Swift to repoint the narrow field instruments to the burst position ∼ 350 s before the main burst occurred...
This paper proposes an automatic acoustic-phonetic method for estimating voice-onset time of stops. This method requires neither transcription of the utterance nor training of a classifier. It makes use of the plosion index for the automatic detection of burst onsets of stops. Having detected the burst onset, the onset of the voicing following the burst is detected using the epochal information...
WiMAX OFDMA downlink subframes have a special 2-D channel time structure. The resource allocations from this structure incur extra control overheads that hurt network performance. Existing solutions try to improve network performance by designing either the scheduler in the MAC layer or the burst allocator in the physical layer, but the efficiency of overhead reduction is limited. In this paper...
GRB 040403 is one of the faintest gamma-ray bursts for which a rapid and accurate localization has been obtained. Here we report on the gamma-ray properties of this burst, based on observations with the IBIS instrument aboard INTEGRAL, and the results of searches for its optical afterglow. The steep spectrum (power law photon index = 1.9 in the 20-200 keV range) implies that GRB 040403 is most ...
The synchrotron shock model (SSM) for gamma-ray burst emission makes a testable prediction: that the observed low-energy power-law photon number spectral index cannot exceed −2/3 (where the photon model is defined with a positive index: dN/dE ∝ E α). We have collected time-resolved spectral fit parameters for over 100 bright bursts observed by the Burst And Transient Source Experiment on board ...
