Analysis of the Dynamics of a $\phi^{6}$ Duffing Type Jerk System

Chaos Theory and Applications
A theoretically and numerically analysis on Duffing Jerk systems with a sixth-order type potential and a sixth-order potential smoothed by a gaussian function are carried out in this work.

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

FEBS 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.

GIMIC: smoothed graph-image representation of microbiome samples induce an optimal distance

Genome Biology
An essential tool in microbiome is the distance between samples. This serves to detect groups of similar samples. We have recently shown that combining the cladogram with the abundance of each microbe into a sorted normalized abundance tree can improve ...

A Fast Smoothing Algorithm for Post-Processing of Surface Reflectance Spectra Retrieved from Airborne Imaging Spectrometer Data

Sensors, 2013
Surface reflectance spectra retrieved from remotely sensed hyperspectral imaging data using radiative transfer models often contain residual atmospheric absorption and scattering effects.

Multi‐omics and low‐input proteomics profiling reveals dynamic regulation driving pluripotency initiation in early mouse embryos

FEBS Open Bio, EarlyView.
Mouse pre‐implantation development involves a transition from totipotency to pluripotency. Integrating transcriptomics, epigenetic profiling, low‐input proteomics and functional assays, we show that eight‐cell embryos retain residual totipotency features, whereas cytoskeletal remodeling regulated by the ubiquitin‐proteasome system drives progression ...

Gaussian process emulators for the undrained bearing capacity of spatially random soils using cell-based smoothed finite element method

Journal of Rock Mechanics and Geotechnical Engineering
In this paper, we propose a novel probabilistic method for predicting the undrained bearing capacity of spatially variable soils. Our approach combines a Gaussian process regression (GPR)-based surrogate model with random cell-based smoothed finite ...

Numerical Analysis of Liquid Sloshing Using the Incompressible Smoothed Particle Hydrodynamics Method

Advances in Mechanical Engineering, 2015
A stabilized incompressible smoothed particle hydrodynamics (ISPH) method with the addition of a density invariant relaxation condition in the pressure calculations is applied to simulations of highly nonlinear liquid sloshing problems.

Multivariate Bayesian meta-analysis: joint modelling of multiple cancer types using summary statistics

International Journal of Health Geographics, 2020
Background Cancer atlases often provide estimates of cancer incidence, mortality or survival across small areas of a region or country. A recent example of a cancer atlas is the Australian cancer atlas (ACA), that provides interactive maps to visualise ...

High-frequency asymptotics for Lipschitz-Killing curvatures of excursion sets on the sphere

, 2016
In this paper, we shall be concerned with geometric functionals and excursion probabilities for some nonlinear transforms evaluated on Fourier components of spherical random fields.

Smoothed Analysis of the k-Means Method

Journal of the ACM, 2011
The k -means method is one of the most widely used clustering algorithms, drawing its popularity from its speed in practice. Recently, however, it was shown to have exponential worst-case running time.
