A Joint Source Channel Coding Approach to Delivery of Digital Images over CDMA 800 MHz Indoor Wireless Rayleigh Fading Channels
(Instituto Tecnológico y de Estudios Superiores de Monterrey, 2015)
Chaotic model and memory in single calcium-activated potassium channel kinetics
(AMER INST PHYSICS, 2008)
Ion channels are pores formed by proteins and responsible for carrying ion fluxes through cellular membranes. The ion channels can assume conformational states thereby controlling ion flow. Physically, the conformational ...
Benzenesulfonamides act as open-channel blockers on K V 3.1 potassium channel
(2019-02-07)
K V 3.1 blockers can serve as modulators of the rate of action potential firing in neurons with high rates of firing such as those of the auditory system. We studied the effects of several bioisosteres of N-alkylbenzenes ...
Telephone Channel Compensation in Speaker Verification Using a Polynomial Approximation in the Log-Filter-Bank Energy Domain
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2012-01)
This correspondence presents a novel feature-space channel compensation technique that models the convolutional distortion in the log-energy mel-filter domain by means of a polynomial approximation. The proposed parametric ...
Intrinsic electrostatic potential in the BK channel pore: Role in determining single channel conductance and block
(ROCKEFELLER UNIV PRESS, 2008-02)
The internal vestibule of large-conductance Ca2+ voltage-activated K+ (BK) channels contains a ring of eight negative charges not present in K+ channels of lower conductance (Glu386 and Glu389 in hSlo) that modulates channel ...
Morphodynamics and seismostratigraphy of a deep hole at tidal channel confluence
(Elsevier Science, 2009-12)
The sedimentary circulation pattern at a deep hole at a tidal channel junction in an estuary environment is examined using morphosedimentological and seismostratigraphic data. The bottom and sub-bottom acoustic information ...
Machine Learning-Based 5G-and-Beyond Channel Estimation for MIMO-OFDM Communication Systems
(Sensors (Basel), 2021)
Channel estimation plays a critical role in the system performance of wireless networks. In addition, deep learning has demonstrated significant improvements in enhancing the communication reliability and reducing the ...
Surface-Potential-Based Drain Current Analytical Model for Triple-Gate Junctionless Nanowire Transistors
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
This paper proposes a drain current model for triple-gate n-type junctionless nanowire transistors. The model is based on the solution of the Poisson equation. First, the 2-D Poisson equation is used to obtain the effective ...
