General Randić matrix and general randic energy
Transactions on Combinatorics, 2014 Summary: Let \(G\) be a simple graph with vertex set \(V(G) = \{v_1, v_2,\dots, v_n\}\) and \(d_i\) the degree of its vertex \(v_i\), \(i = 1, 2, \dots, n\). Inspired by the Randić matrix and the general Randić index of a graph, we introduce the concept of general Randi'c matrix \(\mathbf{R}_\alpha\) of \(G\), which is defined by \((\mathbf{R}_\alpha)_{

Generalized Quaternions and Matrix Algebra
Afyon Kocatepe University Journal of Sciences and Engineering, 2023 In this paper, we established the connection between generalized quaternion algebra and real (complex) matrix algebras by using Hamilton operators. We obtained real and complex matrices corresponding to the real and complex basis of the generalized quaternions. Also, we investigated the basis features of real and complex matrices. We get Pauli matrices

FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Some New Optimal Skew Cyclic Codes With Derivation
IEEE AccessOur study included a class of cyclic codes named $\delta _{\alpha,\zeta }-$ cyclic codes over the ring $\mathcal {R}=\mathbb {F}_{2^{m}} + u\mathbb {F}_{2^{m}}+u^{2}\mathbb {F}_{2^{m}}$ , where m is an odd positive integer with $u^{3}=1$ . These codes

Research on Characteristics of RC Polyphase Network for Quadrature Signal Generator
Leida xuebao, 2013 The quadrature signal generator is widely used in devices such as the quadrature modulator and image rejection frequency converter. An RC polyphase network is commonly used as a quadrature signal generator because of its simple structure and perfect ...

Making extreme computations possible with virtual machines
, 2016 State-of-the-art algorithms generate scattering amplitudes for high-energy physics at leading order for high-multiplicity processes as compiled code (in Fortran, C or C++). For complicated processes the size of these libraries can become tremendous (many

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

An event generator for same-sign W-boson scattering at the LHC including electroweak corrections
European Physical Journal C: Particles and Fields, 2019 In this article we present an event generator based on the Monte Carlo program Powheg in combination with the matrix-element generator Recola. We apply it to compute NLO electroweak corrections to same-sign W-boson scattering, which have been shown to be

Lossy Source Coding via Spatially Coupled LDGM Ensembles
, 2012 We study a new encoding scheme for lossy source compression based on spatially coupled low-density generator-matrix codes. We develop a belief-propagation guided-decimation algorithm, and show that this algorithm allows to approach the optimal distortion
