Reviewing HIV-1 Gag Mutations in Protease Inhibitors Resistance: Insights for Possible Novel Gag Inhibitor Designs

open access: yesMolecules, 2019
HIV protease inhibitors against the viral protease are often hampered by drug resistance mutations in protease and in the viral substrate Gag. To overcome this drug resistance and inhibit viral maturation, targeting Gag alongside protease rather than ...

Energy production in stars [PDF]

open access: yesPhysics Today, 1939
FROM TIME IMMEMORIAL people must have been curious to know what keeps the sun shining. The first scientific attempt at an explanation was by Helmholtz about one hundred years ago, and was based on the force most familiar to physicists at the time, gravitation. When a gram of matter falls to the sun's surface it gets a potential energy Epot = −GM/R = −1.

A Comparison between Star Products on Regular Orbits of Compact Lie Groups [PDF]

open access: yes, 2001
In this paper an algebraic star product and differential one defined on a regular coadjoint orbit of a compact semisimple group are compared. It is proven that there is an injective algebra homomorphism between the algebra of polynomials with the ...

Online Prognosis of Bimodal Crack Evolution for Fatigue Life Prediction of Composite Laminates Using Particle Filters

open access: yesApplied Sciences, 2021
Composite materials are extensively used in aircraft structures, wherein they are subjected to cyclic loads and subsequently impact-induced damages. Progressive fatigue degradation can lead to catastrophic failure.

A Path Integral Approach To Noncommutative Superspace [PDF]

open access: yes, 2003
A path integral formula for the associative star-product of two superfields is proposed. It is a generalization of the Kontsevich-Cattaneo-Felder's formula for the star-product of functions of bosonic coordinates.

Symmetrization of the Berezin star product and multiple star product method [PDF]

open access: yesJournal of Physics A: Mathematical and General, 2001
We construct a multiple star product method and by using this method, show that integral forms of some star products can be written in terms of the path-integral. This method can be applied to some examples. Especially, the associativity of the skew-symmetrized Berezin star product proposed in \cite{SW}, is recovered in large $N$ limit of the multiple ...

Understanding of Customer Decision-Making Behaviors Depending on Online Reviews

open access: yesApplied Sciences, 2023
With a never-ending stream of reviews propagating online, consumers encounter countless good and bad reviews. Depending on which reviews consumers read, they get a different impression of the product. In this paper, we focused on the relationship between

Enhanced photonics devices based on low temperature plasma-deposited dichlorosilane-based ultra-silicon-rich nitride (Si8N)

open access: yesScientific Reports, 2022
Ultra-silicon-rich nitride with refractive indices ~ 3 possesses high nonlinear refractive index—100× higher than stoichiometric silicon nitride and presents absence of two-photon absorption, making it attractive to be used in nonlinear integrated optics

Seiberg-Witten map with Lorentz-invariance and gauge-covariant star product

open access: yesNuclear Physics B, 2022
We develop the Seiberg-Witten map using the gauge-covariant star product with the noncommutativity tensor θμν(x). The latter guarantees the Lorentz invariance of the theory.
