Effectiveness of Hyperthermic Intraperitoneal Chemotherapy Associated with Cytoreductive Surgery in the Treatment of Advanced Ovarian Cancer: Systematic Review and Meta-Analysis
MDPI (2023-01-30)Objective: The use of hyperthermic intraperitoneal chemotherapy (HIPEC) as a treatment for epithelial ovarian cancer remains controversial. Our study aims to analyze the overall survival and disease-free survival for the ... -
Efficient time integration methods for Gross-Pitaevskii equations with rotation term
American Institute of Mathematical Sciences (2019)The objective of this work is the introduction and investigation of favourable time integration methods for the Gross-Pitaevskii equation with rotation term. Employing a reformulation in rotating Lagrangian coordinates, ...

Eliahou number, Wilf function and concentration of a numerical semigroup
Taylor & Francis (2022-03-30)We give an estimate of the minimal positive value of the Wilf function of a numerical semigroup in terms of its concentration. We describe necessary conditions for a numerical semigroup to have a negative Eliahou number ...

Endograph Metric and a Version of the Arzelà–Ascoli Theorem for Fuzzy Sets
MDPI (2023)In this paper, we provide several Arzelà–Ascoli-type results on the space of all continuous functions from a Tychonoff space X into the fuzzy sets of Rn , (FUSCB(Rn),Hend) , which are upper semi-continuous and have bounded ...

Exponential Perturbative Expansions and Coordinate Transformations
MDPI (2020)We propose a unified approach for different exponential perturbation techniques used in the treatment of time-dependent quantum mechanical problems, namely the Magnus expansion, the Floquet–Magnus expansion for periodic ...

Fast Algorithms for the Computation of the Minimum
Distance of a Random Linear Code
Association for Computing Machinery (ACM) (2019-06)The minimum distance of an error-correcting code is an important concept in information theory. Hence, computing the minimum distance of a code with a minimum computational cost is crucial to many problems in this area. ...

Foliations with isolated singularities on Hirzebruch surfaces
De Gruyter (2021)We study foliations ℱ on Hirzebruch surfaces Sδ and prove that, similarly to those on the projective plane, any ℱ can be represented by a bi-homogeneous polynomial affine 1-form. In case ℱ has isolated singularities, we ...

Fuzzy quasi-pseudometrics on algebraic structures
Elsevier (2018-01)In this work we state a number of theorems about fuzzy (quasi-)pseudometrizable algebraic structures. Our most useful results are: (1) a fuzzy semitopological group whose topology is induced by a left-invariant fuzzy ... -
Generalisation of splitting methods based on modified potentials to nonlinear evolution equations of parabolic and Schrödinger type
Elsevier (2023-11-10)The present work is concerned with the extension of modified potential operator splitting methods to specific classes of nonlinear evolution equations. The considered partial differential equations of Schrödinger and ...

Generalized Linear Models for Geometrical Current predictors. An application to predict garment fit
SAGE Publications (2019)The aim of this paper is to model an ordinal response variable in terms of vector-valued functional data included on a vector-valued RKHS. In particular, we focus on the vector-valued RKHS obtained when a geometrical ...

Generalized Weierstrass semigroups and their Poincaré series.
Elsevier (2019-07)We investigate the structure of the generalized Weierstrass semigroups at several points on a curve defined over a finite field. We present a description of these semigroups that enables us to associate them with combinatorial ...

Global and Local Three-dimensional Studies of The Residual Vector Field from 2MASS and Hipparcos-2 Catalog
Astronomical Society of the Pacific (2019-04)The Gaia mission will provide a six-parameter solution for millions of stars, including a tridimensional map of our Galaxy. The estimation of distances has been made for the Tycho-Gaia Astrometric Solution (TGAS), while ...

High order integrators obtained by linear combinations of symmetric-conjugate compositions
Elsevier (2022-02-01)A new family of methods involving complex coefficients for the numerical integration of differential equations is presented and analyzed. They are constructed as linear combinations of symmetric-conjugate compositions ...

Highly tempering infinite matrices
Springer Milan (2017-02)In this short note, it is proved the existence of in nite matrices that not only preserve convergence and limits of sequences but also convert every mem- ber of some dense vector space consisting, except for zero, of ...

Homomorphic encoders of profinite abelian groups I
Elsevier (2023-05)Let {Gi |i ∈ N} be a family of finite Abelian groups. We say that a subgroup G ≤ i∈N Gi is order controllable if for every i ∈ N there is ni ∈ N such that for each c ∈ G, there exists a ∈ G satisfying that a|[1,i] = ...

Hölder regularity for the Moore-Gibson-Thompson equation with infinite delay
American Institute of Mathematical Sciences (AIMS) (2018-01)We characterize the well-posedness of a third order in time equation with infinite delay in Holder spaces, solely in terms of spectral properties concerning the data of the problem. Our analysis includes the case of the ...

Interpolation sets in spaces of continuous metric-valued functions
Elsevier (2018-10)Let X and K be a Cech-complete topological group and a compact group, ˇ respectively. We prove that if G is a non-equicontinuous subset of CHom(X; K), the set of all continuous homomorphisms of X into K, then there is a ...

Invertibles in topological rings: a new approach
Springer (2021-11-15)Every element in the boundary of the group of invertibles of a Banach algebra is a topological zero divisor. We extend this result to the scope of topological rings. In particular, we define a new class of semi-normed ...

Lipschitz continuity of the dilation of Bloch functions on the unit ball of a Hilbert space and applications
Springer (2024-02-13)Let BE be the open unit ball of a complex finite- or infinite-dimensional Hilbert space. If f belongs to the space B(BE ) of Bloch functions on BE , we prove that the dilation map given by x → (1 − x 2)R f (x) for x ∈ ...

Locally recoverable J-affine variety codes
(2020-06)A locally recoverable (LRC) code is a code over a finite eld Fq such that any erased coordinate of a codeword can be recovered from a small number of other coordinates in that codeword. We construct LRC codes correcting ...
