Hyperbolic/elliptic‐CAP formulation for FRCC based on microplane constitutive theory
Structural Concrete, EarlyView.Abstract The present work describes an elasto‐plastic constitutive formulation aimed at simulating the failure behavior of Fiber Reinforced Cementitious Composites (FRCCs). This proposal, based on the Microplane Theory and Smeared Crack Approach (SCA), assumes a hyperbolic maximum strength criterion for the cementitious matrix in terms of normal and ...

On the Non Metrizability of Berwald Finsler Spacetimes
Universe, 2020 We investigate whether Szabo’s metrizability theorem can be extended to Finsler spaces of indefinite signature. For smooth, positive definite Finsler metrics, this important theorem states that, if the metric is of Berwald type (i.e., its Chern–Rund ...

Existence and uniqueness of Chern connection in the Klein-Grifone approach [PDF]
arXiv, 2014 The Klein-Grifone approach to global Finsler geometry is adopted. A global existence and uniqueness theorem for Chern connection is formulated and proved. The torsion and curvature tensors of Chern connection are derived. Some properties and the Bianchi identities for this connection are investigated.

Compact Kähler manifolds with quasi-positive second Chern-Ricci curvature [PDF]
arXiv, 2020 Let $X$ be a compact K\"ahler manifold. We prove that if $X$ admits a smooth Hermitian metric $\omega$ with quasi-positive second Chern-Ricci curvature $\mathrm{Ric}^{(2)}(\omega)$, then $X$ is projective and rationally connected. In particular, $X$ is simply connected.

A note on Canonical Ricci forms on 2-step nilmanifolds
, 2012 In this note we prove that any left-invariant almost Hermitian structure on a 2-step nilmanifold is Ricci-flat with respect to the Chern connection and that it is Ricci-flat with respect to another canonical connection if and only if it is cosymplectic ...

ERNEST COST action overview on the (patho)physiology of GPCRs and orphan GPCRs in the nervous system
British Journal of Pharmacology, EarlyView.G protein‐coupled receptors (GPCRs) are a large family of cell surface receptors that play a critical role in nervous system function by transmitting signals between cells and their environment. They are involved in many, if not all, nervous system processes, and their dysfunction has been linked to various neurological disorders representing important

Laplace operators on holomorphic Lie algebroids
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2018 The paper introduces Laplace-type operators for functions defined on the tangent space of a Finsler Lie algebroid, using a volume form on the prolongation of the algebroid.

Effective theories for 2+1 dimensional non-Abelian topological spin liquids
Journal of High Energy Physics, 2017 In this work we propose an effective low-energy theory for a large class of 2+1 dimensional non-Abelian topological spin liquids whose edge states are conformal degrees of freedom with central charges corresponding to the coset structure su(2) k ⊕ su(2 ...

The behavior of Chern scalar curvature under Chern-Ricci flow [PDF]
arXiv, 2013 In this note we study finite-time singularities in the Chern-Ricci flow. We show that finite-time singularities are characterized by the blow-up of the scalar curvature of the Chern connection.
