Factorized lightcone expansion of conformal blocks

open access: yesJournal of High Energy Physics, 2021
We present a factorized decomposition of 4-point scalar conformal blocks near the lightcone, which applies to arbitrary intermediate spin and general spacetime dimensions.

Comparative analysis of genetic crossover operators in knapsack problem

open access: yesJournal of Applied Sciences and Environmental Management, 2016
The Genetic Algorithm (GA) is an evolutionary algorithms and technique based on natural selections of individuals called chromosomes. In this paper, a method for solving Knapsack problem via GA (Genetic Algorithm) is presented. We compared six different

Force induced triple point for interacting polymers [PDF]

open access: yes, 2004
We show the existence of a force induced triple point in an interacting polymer problem that allows two zero-force thermal phase transitions. The phase diagrams for three different models of mutually attracting but self avoiding polymers are presented ...

Globule transitions of a single homopolymer: a Wang-Landau Monte Carlo study [PDF]

open access: yes, 2015
The temperature-independent Wang-Landau Monte Carlo approach is implemented for an off-lattice model of flexible homopolymers and applied to the coil-globule and solidification transitions based on chain sizes up to N=300.

On a mean value theorem connected with Hermite-Hadamard's inequality

open access: yesJournal of Numerical Analysis and Approximation Theory, 2004
In this paper we prove a mean-value theorem for integral calculus, then we demonstrate properties of the mean point. In the end we give an extension of Hermite-Hadamard's inequality.

Effects of the turn-back primer on intermediate product generation in isothermal DNA amplification

open access: yesBioTechniques, 2010
In DNA amplification, the initial step of copying a target sequence from the template DNA, or the so-called intermediate product generation step, is very important.

Second order differentiability of the intermediate-point function in Cauchy's mean-value theorem

open access: yesJournal of Numerical Analysis and Approximation Theory, 2015
If the functions \(f,g:I\rightarrow \mathbb{R}\) are differentiable on the interval \(I\subseteq \mathbb{R}\), \(a\in I,\) then there exists a function \(\bar{c}:I\rightarrow I\) such that $$ \left[ f\left( x\right) -f\left( a\right) \right] g ...
