Abstract:
With many efficient solutions for a multi-objective optimization problem, this paper aims to cluster the Pareto Front in a given number of clusters K and to detect isolated points. K-center problems and variants are investigated with a unified formulation considering the discrete and continuous versions, partial K-center problems, and their min-sum-K-radii variants. In dimension three (or upper), this induces NP-hard complexities. In the planar case, common optimality property is proven: non-nested optimal solutions exist. This induces a common dynamic programming algorithm running in polynomi

Abstract:
In this paper, the authors deal with a mean-variance enhanced index tracking (EIT) problem with weights constraints. Using a shrinkage approach, they show that constructing the constrained EIT portfolio is equivalent to constructing the unconstrained EIT portfolio. This equivalence allows to study the effect of weights constraints on the covariance matrix and on the EIT portfolio. In general, the effects of weights constraints on the EIT portfolio are different from those observed in the case of global minimum variance portfolio.

AbstractPetri nets are an established model of concurrency. A Petri net is terminating if for every initial marking there is a uniform bound on the length of all possible runs.

In this paper we focus on the termination of workflow nets, an established variant of Petri nets used for modelling business processes. We partially confirm the intuition on fast termination by showing a dichotomy: workflow nets are either non-terminating or they terminate in linear ti

Abstract:
A violation of the hormonal balance is considered one of the factors affecting the development of osteoporosis (OP). The study of the molecular and genetic aspects of this fact will allow us to select a more effective course of OP therapy in the future. Sex hormones, as activators of the expression of a number of genes that regulate bone metabolism, act indirectly through specific receptors. We considered polymorphic variants of the estrogen receptor genes ESR1 and ESR2, encoding the a and в subunits of the estrogen receptor, respectively. Among the studied polymorphic variants of ESR1 (rs9340

Abstract:
Background: Dravet syndrome (DS) is a rare and severe epileptic syndrome of childhood with a prevalence around 1/40,000 people worldwide. Approximately 80% of patients with DS present SCN1A pathogenic variants, which encodes an alpha subunit of a neural voltage- dependent sodium channel. SCN1A variants were also related to DS. There is a correlation between PCDH19 pathogenic variants, encodes the protocadherin 19, and a similar disease to DS known as DS-like phenotype. Objectives: To clarify the differences between DS and DS-like phenotype according to the SCN1A and PCDH19 variants. Methodolog

Abstract:
Seja G um grafo conexo e P um conjunto de caminhos disjuntos nos vértices em G. Dizemos que P é uma cobertura por caminhos se cada vértice de G pertence a algum caminho em P . No problema da cobertura mínima por caminhos, o objetivo é encontrar uma cobertura com o menor número de caminhos. Nesse problema, que é sabido ser NP-difícil, o conjunto P pode conter caminhos triviais. Estudamos uma variante desse problema onde o objetivo é encontrar uma cobertura sem caminhos triviais. Usando a decomposição de Edmonds-Gallai, mostramos que o problema de decidir se um grafo tem tal cobertura pode ser r

Abstract:
The problem of optimally scheduling the charging demand of electric vehicles within the constraints of the electricity infrastructure is called the charge scheduling problem. The models of the charging speed, horizon, and charging demand determine the computational complexity of the charge scheduling problem. We show that for about 20 variants the problem is either in P or weakly NP-hard and dynamic programs exist to compute optimal solutions. About 10 other variants of the problem are strongly NP-hard, presenting a potentially significant obstacle to their use in practical situations of scale
