Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Numerical modeling for plasmonics

International Journal of Applied Electromagnetics and Mechanics, 2011
This contribution is a review paper, concerning mainly the research work made by the authors, about the numerical modeling, in the frequency domain, of both surface and bulk plasmon oscillations induced in metallic nanoparticles with arbitrary shapes by an external electromagnetic field.

NUMERICAL MODELLING OF DISCONTINUA

Engineering Computations, 1992
Discrete element methods are numerical procedures for simulating the complete behaviour of systems of discrete, interacting bodies. Three important aspects of discrete element programs are examined: (1) the representation of contacts; (2) the representation of solid material; and (3) the scheme used to detect and revise the set of contacts.

Numerical Modeling of Mudflows

Journal of Hydraulic Engineering, 1997
To predict mudflow dynamics a numerical model based on shallow-water equations is developed. Previous work has shown that mudflow behavior can be well represented by a Herschel-Bulkley model. In a laminar regime, generally observed in practice, a wall friction force expression has been theoretically deduced for steady uniform flows.

ON SMOOTH NUMERICAL MODEL

Acta Mathematica Scientia, 1994
An approach to approximate data by smooth numerical models is described. The idea seems to be ``\dots to fit a smooth numerical model to the data, instead of fitting a curve.'' Theoretical backgrounds are partially available and illustrative examples are discussed.

Numerical Modeling of PMD

Journal of Optical and Fiber Communications Reports, 2004
A procedure for evaluating system performance considering all orders of polarization mode dispersion (PMD) is presented. The method provides engineering rules for computing system penalty introduced by PMD. Computer simulation of PMD induced penalty indicates that for generating a realistic system budget, effect of higher order PMD in presence of ...

Numerical Modelling

2018
This chapter deals with the problem of modelling the behaviour of massive concrete structures. In the last decades, the developments in the field of computational mechanics were significant, so nowadays several numerical techniques are available to this goal, depending on the scale level considered but also on which phenomena/processes are taken into ...

A numerical model for large deformation

Proceedings of 13th International Conference on Pattern Recognition, 1996
Motion study in computer vision highly depends on the type of imagery and on the kind of the studied objects. A popular approach of non-rigid motion supposes that the objects are continuously and locally deformed. Local features, such as curvature extrema, are then often used.

Numerical Model of Coarticulation

The Journal of the Acoustical Society of America, 1967
The essential features of the coarticulation properties of Swedish dental stops in vowel-consonant-vowel contexts can be described by the formula s(x; t) = v(x; l)+k (t)[c(x) − v(x; t)]wc(x), where x represents the longitudinal distance between lips and glottis and s(x; t) denotes the shape of the vocal tract at some instant of time, t, during the ...

Numerical modelling

2021
Abstract Modelling and tuning of muon beamlines can be carried out using matrix techniques from optics, or via ray tracing methods. Monte Carlo methods for determining the muon stopping profile allow optimal degrader thicknesses to be computed, and pressure- cell and low-energy measurements to be planned.
