This work examines the computational architecture used by the brain during the analysis of the spectral envelope of sounds, an important acoustic feature for defining auditory objects. Dynamic causal modelling and Bayesian model selection were used to evaluate a family of 16 network models explaining functional magnetic resonance imaging responses in the right temporal lobe during spectral enve...

We study the response of two generic neuron models, the leaky integrate-and-fire (LIF) model and the leaky integrate-and-fire model with dynamic threshold (LIFDT) (i.e., with memory) to a stimulus consisting of two sinusoidal drives with incommensurate frequency, an amplitude modulation ("envelope") noise and a relatively weak additive noise. Spectral and coherence analysis of responses to such...

An office building located in Québec City (QC, Canada) with different envelope assemblies has been simulated to determine the energy consumption and thermal comfort that they provide. The resistance, mass, materials (concrete, cross-laminated timbers (CLT), light-frame) were varied a series of 164 scenarios, intensities for heating cooling determined each case, along discomfort index. Results s...

. The present study deals with a voice quality that is referred to as “intelligible” or “articulate” voice. The purpose of the present study is to find a relation between the voice quality and acoustic features. The speech material is a read version of a simple short Japanese sentence “a o i so ra” in order to eliminate these linguistic variations. A set of speech samples uttered by fifteen adu...

 It is crucial for the spectral-efficient communication systems, associated with the sophisticated digital modulation formats to be able to handle the RF signal containing a probably very large variation of the envelope magnitude. The aim of this work is to build an optimal transmitter linearization architecture suitable to achieve a highly linear transmission and to be highly power efficient....

objective(s): production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. the goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. materials and methods: multiple amino acid sequences of different i...

As an alternative to the shared backup path protection (SBPP) method, we develop a framework for dynamic provisioning of survivable services through the use of p-cycles to form a protected working capacity envelope (PWCE) within which dynamic provisioning of protected services is greatly simplified. With a PWCE, arbitrarily fast dynamic service demands can be handled with much less complexity (...

background and aims. wound dehiscence after lower third molar surgery extends the postoperative treatment period and may cause long-standing pain. the aim of this study was to compare wound dehiscence after removal of wisdom teeth in the most prevalent mandibular impaction (mesioangular class ib) by two different soft tissue flap designs. materials and methods. partially-erupted mandibular thir...

In this paper, a safety envelope concept for load tolerance is introduced. This shows the capacity of the current design as a future reference for design upgrade, maintenance, and control. The safety envelope is applied to estimate the load tolerance of a structural part with respect to the fatigue reliability. First, the dynamic load history is decomposed into the average value and amplitude, ...

The understanding of chloroplast function requires the precise localization of proteins in each of its sub-compartments. High-sensitivity mass spectrometry has allowed the inventory of proteins in thylakoid, stroma, and envelope fractions. Concerning membrane association, proteins can be either integral or peripheral or even soluble proteins bound transiently to a membrane complex. We sought a ...
