Critical points and the presence of pathogenic bacteria in iced beverage processing lines

Journal of Infection in Developing Countries, 2017
Introduction: Ice can be contaminated by pathogenic bacteria. This study aimed to identify critical points in iced beverage production and distribution lines to examine the presence of pathogenic bacteria in a beverage and its processing environment, as

Risk-based Approach in Obtaining and Analysing the Characteristics of Baikal Skullcap Suspension Cultures

Разработка и регистрация лекарственных средств, 2022
Introduction. The use of biologically active compounds of Baikal skullcap (Scutellaria baicalensis Georgi) becomes especially important under pandemic conditions. The plant's value becomes the cause of overexploitation of the skullcap subterranean parts,

First-Order Comprehensive Adjoint Sensitivity Analysis Methodology for Critical Points in Coupled Nonlinear Systems. II: Application to a Nuclear Reactor Thermal-Hydraulics Safety Benchmark

Fluids, 2021
Responses defined at critical points are particularly important for reactor safety analyses and licensing (e.g., the maximum fuel and/or clad temperature).

Typicality at quantum-critical points [PDF]

, 2018
We discuss the concept of typicality of quantum states at quantum-critical points, using projector Monte Carlo simulations of an S = 1/2 bilayer Heisenberg antiferromagnet as an illustration.

First-Order Comprehensive Adjoint Sensitivity Analysis Methodology for Critical Points in Coupled Nonlinear Systems. I: Mathematical Framework

Fluids, 2021
This work presents the novel first-order comprehensive adjoint sensitivity analysis methodology for critical points (1st-CASAM-CP), which enables the exact and efficient computation of the first-order sensitivities of responses defined at critical points

Critical points and supersymmetric vacua [PDF]

, 2004
Supersymmetric vacua (`universes') of string/M theory may be identified with certain critical points of a holomorphic section (the `superpotential') of a Hermitian holomorphic line bundle over a complex manifold.

Simple dynamical systems

Applied General Topology, 2019
In this paper, we study the class of simple systems on R induced by homeomorphisms having finitely many non-ordinary points. We characterize the family of homeomorphisms on R having finitely many non-ordinary points upto (order) conjugacy.

Investigation of spectrum curves for a Sturm-Liouville problem with two-point nonlocal boundary conditions

Mathematical Modelling and Analysis, 2020
The article investigates the Sturm–Liouville problem with one classical and another nonlocal two-point boundary condition. We analyze zeroes, poles and critical points of the characteristic function and how the properties of this function depend on ...

Existence and multiplicity results for nonlinear problems involving the p(x)-Laplace operator [PDF]

Opuscula Mathematica, 2014
In this paper we study the following nonlinear boundary-value problem \[-\Delta_{p(x)} u=\lambda f(x,u) \quad \text{ in } \Omega,\] \[|\nabla u|^{p(x)-2}\frac{\partial u}{\partial \nu}+\beta(x)|u|^{p(x)-2}u=\mu g(x,u) \quad \text{ on } \partial\Omega ...

Universal Dynamics Near Quantum Critical Points [PDF]

, 2010
We give an overview of the scaling of density of quasi-particles and excess energy (heat) for nearly adiabatic dynamics near quantum critical points (QCPs).
