Theoretical models: necessary reflections. [PDF]

open access: yesRev Bras Epidemiol, 2023
ABSTRACT Objective: To present theoretical-methodological reflections on the elaboration, types, and functions of theoretical models as well as their conceptual and analytic frameworks. Methods: This is an essay, whose material collection was carried out in a non-systematic way, by electing studies exclusively based on the line of argument and ...

A common gene drive language eases regulatory process and eco-evolutionary extensions

open access: yesBMC Ecology and Evolution, 2021
Background Synthetic gene drive technologies aim to spread transgenic constructs into wild populations even when they impose organismal fitness disadvantages. The extraordinary diversity of plausible drive mechanisms and the range of selective parameters

Monotone Simultaneous Paths Embeddings in $\mathbb{R}^d$ [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2018
We study the following problem: Given $k$ paths that share the same vertex set, is there a simultaneous geometric embedding of these paths such that each individual drawing is monotone in some direction?

Linear Encodings of Bounded LTL Model Checking [PDF]

open access: yesLogical Methods in Computer Science, 2006
We consider the problem of bounded model checking (BMC) for linear temporal logic (LTL). We present several efficient encodings that have size linear in the bound.

Approach to theoretical perspectives of “sexual harassment”: review and bibliometric analysis from social sciences

open access: yesFrontiers in Psychology, 2023
The main goal of this paper is to give an overlook of the current state of sexual harassment. In order to do so, we started making a synthesis of the main theoretical approaches to explain sexual harassment, trying to group the studies into different ...

Z-plasty: a comparative study between theoretical and practical elongation [PDF]

open access: yesRevista Brasileira de Cirurgia Plástica, 2016
INTRODUCTION: The study of the final elongation values produced by 45º, 60º, 75º, and 90º-angle z-plasties performed on the skin of the lower abdomen of fresh cadavers were compared with the theoretical mathematical data published in the literature.

Structural Disorder and Collective Behavior of Two-Dimensional Magnetic Nanostructures

open access: yesNanomaterials, 2021
Structural disorder has been shown to be responsible for profound changes of the interaction-energy landscapes and collective dynamics of two-dimensional (2D) magnetic nanostructures. Weakly-disordered 2D ensembles have a few particularly stable magnetic
