On infinitesimal conformal transformations with respect to the Cheeger-Gromoll metric
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012 The present paper deals with the classification of infinitesimal fibre-preserving conformal transformations on the tangent bundle, equipped with the Cheeger-Gromoll ...

Rigidity properties of holomorphic Legendrian singularities [PDF]
Épijournal de Géométrie Algébrique, 2019 We study the singularities of Legendrian subvarieties of contact manifolds in the complex-analytic category and prove two rigidity results. The first one is that Legendrian singularities with reduced tangent cones are contactomorphically biholomorphic to

A Noninvasive Approach to Study Localized Forces in 3D Epithelia
Advanced Materials, EarlyView.Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

$T-$bundle: A generalization of tangent bundle
, 2019 The purpose of this paper is, to generalize the concept of tangent bundle and some definitions and theorems. In section $2$, we review the concepts of $T-$bundle and Lie algebra of the sections of such objects.

New hyper-Käahler structures on tangent bundles [PDF]
, 2004 summary:Let $(M,g,J)$ be an almost Hermitian manifold, then the tangent bundle $TM$ carries a class of naturally defined almost hyper-Hermitian structures $(G,J_1,J_2,J_3)$.

Advanced Materials, EarlyView.A method to synthesize 1 million compositionally distinct Cs3Bi2‐𝛼Sb𝛼Br9−xIx across a quaternary compositional space on a single glass substrate is presented. High‐throughput characterization is then used to map the interplay of composition, structure, and bandgap.

On the geometry of tangent bundles
Expositiones Mathematicae, 2002 First, the autors recall in their own language and notations the properties of the Sasaki metric on the tangent bundle \(TM\) of a smooth manifold \(M\). Secondly, they consider the Cheeger-Gromoll metric on \(TM\) and reprove in all details the recent results on this metric due to \textit{O. Kowalski} and \textit{M. Sekizawa} [ Bull.

Life‐Like Ferrous Oxide Microspheres from Kombucha
Advanced Materials Interfaces, EarlyView.Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Advanced Materials Technologies, EarlyView.Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined
