Theoretical Investigation and Design of Novel Cephalosporin Based Inhibitors of a DD-carboxypeptidase Enzyme of Salmonella typhimurium [PDF]

open access: yesJournal of Chemistry Letters, 2023
The rising mortality and morbidity associated with Salmonella typhimurium induced salmonellosis aggravated by the emergence of multi-drug resistant strains of this pathogenic bacterium has made continuous search for novel antibiotics a necessity.

Particle and Particle Agglomerate Size Monitoring by Scanning Probe Microscope

open access: yesApplied Sciences, 2022
In the present study, the use of a scanning probe microscope is described for monitoring the sizes of nanoparticles. Monitoring is the process of acquiring and analysing the set of overlapping images.

New stability tests for fractional positive descriptor linear systems [PDF]

open access: yesArchives of Control Sciences, 2023
The asymptotic stability of fractional positive descriptor continuous-time and discretetime linear systems is considered. New sufficient conditions for stability of fractional positive descriptor linear systems are established.

A Deep Learning-Based Hyperspectral Keypoint Representation Method and Its Application for 3D Reconstruction

open access: yesIEEE Access, 2022
In previous studies, the keypoints and their feature descriptors of a hyperspectral image have not received enough attention. Compared with RGB images, the rich feature information of a hyperspectral image can not only constrain the spatial positions of ...

Universal‐Descriptors‐Guided Design of Single Atom Catalysts toward Oxidation of Li2S in Lithium–Sulfur Batteries

open access: yesAdvanced Science, 2021
The sulfur redox kinetics critically matters to superior lithium–sulfur (Li–S) batteries, for which single atom catalysts (SACs) take effect on promoting Li2S redox process and mitigating the shuttle behavior of lithium polysulfide (LiPs).

Analysis of Application of Cluster Descriptions in Space of Characteristic Image Features

open access: yesData, 2018
In this paper, we propose an investigation of the properties of structural image recognition methods in the cluster space of characteristic features. Recognition, which is based on key point descriptors like SIFT (Scale-invariant Feature Transform), SURF

Extending the sGLOH Descriptor [PDF]

open access: yes, 2015
This paper proposes an extension of the sGLOH keypoint descriptor [3] which improves its robustness and discriminability. The sGLOH descriptor can handle discrete rotations by a cyclic shift of its elements thanks to its circular structure, but its performance can decrease when the keypoint relative rotation is in between two sGLOH discrete rotations ...

Analysis of the fractional descriptor linear systems by the decomposition into the dynamical and static parts [PDF]

open access: yesArchives of Control Sciences
A new method of the decomposition of the fractional descriptor linear continuoustime and discrete-time systems into dynamical and static parts is proposed.
