Energy and position resolution of a CdZnTe gamma-ray detector with orthogonal coplanar anodes [PDF]

, 1999
We report on the simulation, construction and performance of prototype CZT imaging detectors employing orthogonal coplanar anodes. These detectors employ a novel electrode geometry with non-collecting anode strips in 1D and collecting anode pixels ...

Quadrature decomposition of optical fields using two orthogonal phase sensitive amplifiers

, 2014
We propose a new technique to optically process coherent signals by simultaneously extracting their two (I and Q) quadrature components into two orthogonal polarizations at the same frequency.

Signal Processing, Orthogonal Polynomials, and Heun Equations [PDF]

, 2020
A survey of recents advances in the theory of Heun operators is offered. Some of the topics covered include: quadratic algebras and orthogonal polynomials, differential and difference Heun operators associated to Jacobi and Hahn polynomials, connections with time and band limiting problems in signal processing.

Multifrequency broadband polarized horn antenna [PDF]

, 1981
A corrugated conical horn antenna is simultaneously fed a multiplicity of signals, two for each of five frequencies, with each of a pair of signals fed in each of two orthogonal planes for excitation of a desired spherical hybrid mode.

Constructive updating/downdating of oblique projectors: a generalization of the Gram-Schmidt process [PDF]

, 2007
A generalization of the Gram-Schmidt procedure is achieved by providing equations for updating and downdating oblique projectors. The work is motivated by the problem of adaptive signal representation outside the orthogonal basis setting.

Integrated genomic and proteomic profiling reveals insights into chemoradiation resistance in cervical cancer

Molecular Oncology, EarlyView.
A comprehensive genomic and proteomic analysis of cervical cancer revealed STK11 and STX3 as a potential biomarkers of chemoradiation resistance. Our study demonstrated EGFR as a therapeutic target, paving the way for precision strategies to overcome treatment failure and the DNA repair pathway as a critical mechanism of resistance.

A Rotated Quasi-Orthogonal Space-Time Block Code for Asynchronous Cooperative Diversity

Entropy, 2012
The rotated quasi-orthogonal space-time block code (RQSTBC) for asynchronous cooperative diversity is proposed in this paper. The source selects half of the symbols from a signal constellation set and the other half of them from that constellation ...

A new result on recovery sparse signals using orthogonal matching pursuit

Statistical Theory and Related Fields, 2022
Orthogonal matching pursuit (OMP) algorithm is a classical greedy algorithm widely used in compressed sensing. In this paper, by exploiting the Wielandt inequality and some properties of orthogonal projection matrix, we obtained a new number of ...

Possibility between earthquake and explosion seismogram differentiation by discrete stochastic non-Markov processes and local Hurst exponent analysis

, 2001
The basic purpose of the paper is to draw the attention of researchers to new possibilities of differentiation of similar signals having different nature.
