On Determinants of Laplacians on Compact Riemann Surfaces Equipped with Pullbacks of Conical Metrics by Meromorphic Functions [PDF]

, 2018
Let $\mathsf m$ be any conical (or smooth) metric of finite volume on the Riemann sphere $\Bbb CP^1$. On a compact Riemann surface $X$ of genus $g$ consider a meromorphic funciton $f: X\to {\Bbb C}P^1$ such that all poles and critical points of $f$ are ...

Advancing Research on Biomaterials and Biological Materials with Scanning Electron Microscopy under Environmental and Low Vacuum Conditions

Advanced Engineering Materials, EarlyView.
Herein, environmental scanning electron microscopy (ESEM) is discussed as a powerful extension of conventional SEM for life sciences. By combining high‐resolution imaging with variable pressure and humidity, ESEM allows the analysis of untreated biological materials, supports in situ monitoring of hydration‐driven changes, and advances the functional ...

Spherical metrics with conical singularities on a 2-sphere: angle constraints [PDF]

, 2015
In this article, we give a criterion for the existence of a metric of curvature 1 on a 2-sphere with n conical singularities of prescribed angles 2πθ1,...,2πθn and non-coaxial holonomy.

Can Ti‐Based MXenes Serve as Solid Lubricants for Brake Applications? A Tribological Study

Advanced Engineering Materials, EarlyView.
This study explores the first implementation of Ti‐based MXenes materials in brake pad friction composite material. The resulting composite material exhibits a 48% reduction in the wear rate; alongside significant improvements are observed for thermal and mechanical properties.

BEHAVIOUR OF CONICAL SURFACES DURING THE ELECTROCHEMICAL MACHINING PROCESS

Nonconventional Technologies Review, 2016
The electrochemical machining process is based on the material removal from workpiece as a consequence of electrochemical reactions developed between the workpiece material and electrolyte, when both tool electrode and workpiece are found in an ...

The thick-thin decomposition and the bilipschitz classification of normal surface singularities

, 2012
We describe a natural decomposition of a normal complex surface singularity $(X,0)$ into its "thick" and "thin" parts. The former is essentially metrically conical, while the latter shrinks rapidly in thickness as it approaches the origin.

Geodesic Conic Subdivision Curves on Surfaces [PDF]

2011 24th SIBGRAPI Conference on Graphics, Patterns and Images, 2011
In this paper we present a nonlinear curve subdivision scheme, suitable for designing curves on surfaces. Starting with a geodesic control polygon with vertices on a surface, the scheme generates a sequence of geodesic polygons that converges to a continuous curve on the surface. In the planar case, the limit curve is a conic Bezier spline curve.

Transfer of Energy and Momentum Between Magnetoactive Surface Microstructure and a Solid Object

Advanced Engineering Materials, EarlyView.
We demonstrate that magnetoactive multilamellar arrays subjected to a rotating magnetic field can function as platforms for controlled transport of physical objects. Through systematic experimental investigation, we elucidate the underlying physical mechanisms determining the upper limit of the achievable transportation speed in such magnetic “conveyor‐

Injector for use in high voltage isolators for liquid feed lines [PDF]

, 1973
An improved injector is described for use in introducing fluid substances into feed lines employed in delivering flowing bodies of liquids. The injector includes a porous plug, concentrically related to a feed line, including an internally tapered ...

Hartree-Fock symmetry breaking around conical intersections

, 2018
We study the behavior of Hartree-Fock (HF) solutions in the vicinity of conical intersections. These are here understood as regions of a molecular potential energy surface characterized by degenerate or nearly-degenerate eigenfunctions with identical ...
