Self-Consistent Parameterization of DNA Residues for the Non-Polarizable AMBER Force Fields

open access: yesLife, 2022
Fixed-charge (non-polarizable) forcefields are accurate and computationally efficient tools for modeling the molecular dynamics of nucleic acid polymers, particularly DNA, well into the µs timescale.

Derivation of inner magnetospheric electric field (UNH-IMEF) model using Cluster data set [PDF]

open access: yesAnnales Geophysicae, 2008
We derive an inner magnetospheric electric field (UNH-IMEF) model at L=2–10 using primarily Cluster electric field data for more than 5 years between February 2001 and October 2006.

F-derivations on residuated multilattices [PDF]

open access: yesJournal of Hyperstructures, 2019
In this paper, we introduce as a generalization of the concept of derivation, the notion of f-derivation on residuated multilattices and investigate several of its properties.

Development and Validation of a Nomogram for Predicting the Risk of Adverse Cardiovascular Events in Patients with Coronary Artery Ectasia

open access: yesJournal of Cardiovascular Development and Disease, 2021
Coronary artery ectasia (CAE) is a rare finding and is associated with poor clinical outcomes. However, prognostic factors are not well studied and no prognostication tool is available.

The Set Where an Approximate Derivative is a Derivative [PDF]

open access: yesProceedings of the American Mathematical Society, 1976
Let f : [ 0 , 1 ] → R f:[0,1] \to R possess a finite approximate derivative f ap ′ f_{\operatorname {ap}}’ Let E E be the set of points x x where f f is actually ...

On Extended Neoteric Ranked Set Sampling Plan: Likelihood Function Derivation and Parameter Estimation

open access: yesComplexity, 2022
The extended neoteric ranked set sampling (ENRSS) plan proposed by Taconeli and Cabral has proven to outperform many one stages and two stages ranked set sampling plans when estimating the mean and the variance for different populations.

Derived and Integral Sets of Basic Sets of Polynomials [PDF]

open access: yesProceedings of the American Mathematical Society, 1953
For the general terminology used in this paper the reader is referred to Whittaker's books [2; 3]. I shall investigate the mode of increase and the effectiveness of basic derived and integral sets of any finite order. So far as I know, this is done here for the first time. Let pn(z)= i p iziq n(z) = q qizi be two basic sets; then the product set {Un(z)

Categorization via movement: the syntax and semantics of ambos [PDF]

open access: yesDELTA: Documentação de Estudos em Lingüística Teórica e Aplicada, 2020
In order to explain the syntactic behavior and describe the meaning of the item ambos in Brazilian Portuguese, we propose, assuming the Distributed Morphology framework, (1) that the acategorial root amb- merges, in the syntactic derivation, to a D that ...

On Equality of Certain Derivations of Lie Algebras

open access: yesDiscussiones Mathematicae - General Algebra and Applications, 2019
Let L be a Lie algebra. A derivation α of L is a commuting derivation (central derivation), if α (x) ∈ CL (x) (α (x) ∈ Z (L)) for each x ∈ L. We denote the set of all commuting derivations (central derivations) by 𝒟 (L) (Derz (L)).

A model to predict unstable carotid plaques in population with high risk of stroke

open access: yesBMC Cardiovascular Disorders, 2020
Background Several models have been developed to predict asymptomatic carotid stenosis (ACS), however these models did not pay much attention to people with lower level of stenosis (
