Determination of Ferrous Oxide Nanoparticles Minimum Inhibitory Concentration against Local Virulent Bacterial Isolates [PDF]

open access: yesArchives of Razi Institute, 2021
The improvement of multi-resistance properties of the bacterial pathogen has recently been discussed as an emerging issue. In this regard, iron oxide nanoparticles have attracted the researchers’ attention due to their wide application in the realm of ...

Identification of Flow Regimes Based on Adaptive Learning and Additional Momentum BP Neural Network for Electrical Capacitance Tomography

open access: yesJournal of Harbin University of Science and Technology, 2018
Traditional BP neural network is a typical mehtod to solve ECT system of flow pattern identification. It is applied to the simple problems in industrial applications,but there are many defects in solving complex industrial problems. In this paper based

An Optimized K-Harmonic Means Algorithm Combined with Modified Particle Swarm Optimization and Cuckoo Search Algorithm

open access: yesJournal of Intelligent Systems, 2015
Among the data clustering algorithms, the k-means (KM) algorithm is one of the most popular clustering techniques because of its simplicity and efficiency. However, KM is sensitive to initial centers and it has a local optima problem.

Preference of small molecules for local minimum conformations when binding to proteins. [PDF]

open access: yesPLoS ONE, 2007
It is well known that small molecules (ligands) do not necessarily adopt their lowest potential energy conformations when binding to proteins. Analyses of protein-bound ligand crystal structures have reportedly shown that many of them do not even adopt ...

Local Intrinsic Density Based Community Detection Using Branch-and-Bound and Minimum Spanning Tree

open access: yesSystems and Soft Computing, 2022
Community detection in complex networks has emerged as a fundamental research area during the last decade. Traditional community detection is primarily based on static techniques, which are neither practicable regarding limited resources nor appropriate ...

Normal-mode-analysis-monitored energy minimization procedure for generating small-molecule bound conformations. [PDF]

open access: yesPLoS ONE, 2007
The energy minimization of a small molecule alone does not automatically stop at a local minimum of the potential energy surface of the molecule if the minimum is shallow, thus leading to folding of the molecule and consequently hampering the generation ...

Maximum and minimum of local times for two-dimensional random walk [PDF]

open access: yes, 2014
We obtain the leading orders of the maximum and the minimum of local times for the simple random walk on the two-dimensional torus at time proportional to the cover time.
