Geometria Interioara [PDF]

open access: yes, 2000
In ultimii 30 de ani se raspandeste tot mai mult in lume cuvantul transdisciplinaritate. Fiind adesea confundat cu pluridisciplinaritatea si interdisciplinaritatea, se impun cateva precizari.

Scalar Field Evolution at Background and Perturbation Levels for a Broad Class of Potentials

open access: yesFortschritte der Physik, Volume 71, Issue 10-11, November 2023., 2023
Abstract In this paper, a non‐interacting scalar field cosmology with an arbitrary potential using the f‐deviser method that relies on the differentiability properties of the potential is investigated. Using this alternative mathematical approach, a unified dynamical system analysis at a scalar field's background and perturbation levels with arbitrary ...

A footnote to a theorem of Kawamata

open access: yesMathematische Nachrichten, Volume 296, Issue 10, Page 4739-4744, October 2023., 2023
Abstract Kawamata has shown that the quasi‐Albanese map of a quasi‐projective variety with log‐irregularity equal to the dimension and log‐Kodaira dimension 0 is birational. In this note, we show that under these hypotheses the quasi‐Albanese map is proper in codimension 1 as conjectured by Iitaka.

Morse–Radó theory for minimal surfaces

open access: yesJournal of the London Mathematical Society, Volume 108, Issue 4, Page 1669-1700, October 2023., 2023
Abstract For a class of functions (called minimal Radó functions) that arise naturally in minimal surface theory, we bound the number of interior critical points (counting multiplicity) in terms of the boundary data and the Euler characteristic of the domain of the function.

Rapid imaging in the field followed by photogrammetry digitally captures the otherwise lost dimensions of plant specimens

open access: yesApplications in Plant Sciences, Volume 11, Issue 5, September-October 2023., 2023
Abstract Premise We recognized the need for a customized imaging protocol for plant specimens at the time of collection for the purpose of three‐dimensional (3D) modeling, as well as the lack of a broadly applicable photogrammetry protocol that encompasses the heterogeneity of plant specimen geometries and the challenges introduced by processes such as

Dynamical Analysis in Chameleon Dark Energy

open access: yesFortschritte der Physik, Volume 71, Issue 8-9, September 2023., 2023
Abstract A detailed analysis of the phase‐space for the field equations in scalar field cosmology with a chameleon cosmology in a spatially flat Friedmann–Lemaître–Robertson–Walker spacetime is presented. For the matter source it is assumed that it is an ideal gas with a constant equation of state parameter, while for the scalar field potential and the

The influence of equine hoof conformation on the initiation and progression of laminitis

open access: yesEquine Veterinary Journal, Volume 55, Issue 5, Page 862-871, September 2023., 2023
Abstract Background The health and performance of horses are significantly affected by diseases associated with the hoof. Laminitis is a critical hoof disease that causes pain and, potentially, severe hoof and bone pathology. Objective To generate an equine hoof finite element (FE) model to investigate the impact of normal and toe‐in hoof conformations

Geometria responsiva [PDF]

open access: yes, 2012
Il progetto industriale, così come quello architettonico, manifesta un’attenzione crescente verso comportamenti di tipo “responsivo”. Gli oggetti, sia nella piccola scala del Design, sia nella più grande scala dell’architettura, sono sempre più ...
