Quasi-filiform Leibniz algebras of maximum length
(Springer, 2011)
The n-dimensional p-filiform Leibniz algebras of maximum length have already been studied with 0 p 2. For Lie algebras whose nilindex is equal to n − 2 there is only one characteristic sequence, (n − 2, 1, 1), while ...

Neonatal exposure to androgens dynamically alters gut microbiota architecture
(BioScientifica, 2020)
Gonadal steroids strongly contribute to the metabolic programming that shapes the susceptibility to the manifestation of diseases later in life, and the effect is often sexually dimorphic. Microbiome signatures, together ...

Inf-Sup Stable Finite Element Methods for the Landau--Lifshitz--Gilbert and Harmonic Map Heat Flow Equations
(SIAM: Society for Industrial and Applied Mathematics, 2017)
In this paper we propose and analyze a finite element method for both the harmonic map heat and Landau–Lifshitz–Gilbert equation, the time variable remaining continuous. Our starting point is to set out a unified saddle ...

Dilatancy in dry granular flows with a compressible μ(I) rheology
(Elsevier, 2021)
Dilatancy plays a key role in mixtures of grains and fluid but is poorly investigated in dry granular flows. These flows may however dilate by more than 10% in granular column collapses. We investigate here dilatancy effects ...

Steel heat treating: Mathematical modelling and numerical simulation of a problem arising in the automotive industry
(ASTES Publishers, 2017)
We describe a mathematical model for the industrial heating and cooling processes of a steel workpiece representing the steering rack of an automobile. The goal of steel heat treating is to provide a hardened surface on ...

Multi-objective integration of timetables, vehicle schedules and user routings in a transit network
(Elsevier, 2017)
The Transit Network Timetabling and Scheduling Problem (TNTSP) aims at determining anoptimal timetable for each line of a transit network by establishing departure and arrivaltimes at each station and allocating a vehicle ...

Isogroups and isosubgroups
(Real Academia de Ciencias Exactas, Físicas y Naturales, 2003)
The main goal of this paper is to give a mathematical foundation, serious and consistent, to some parts of Santilli’s isotheory. We study the isotopic liftings of groups and subgroups and we also deal with the differences ...

Timely-automatic procedure for estimating the endocardial limits of the left ventricle assessed echocardiographically in clinical practice
(MDPI, 2020-01-13)
In this paper, we propose an analytical rapid method to estimate the endocardial borders of the left ventricular walls on echocardiographic images for prospective clinical integration. The procedure was created as a ...

A multilayer method for the hydrostatic Navier-Stokes equations: a particular weak solution
(Ed. Plenum Press, 2014)
In this work we present a mutilayer approach to the solution of non-stationnary 3D Navier-Stokes equations. We use piecewise smooth weak solutions. We approximate the velocity by a piecewise constant (in z) horizontal ...
