Euclidean analysis of the entropy functional formalism

, 2008
The attractor mechanism implies that the supersymmetric black hole near horizon solution is defined only in terms of the conserved charges and is therefore independent of asymptotic moduli.

Attenuated Nuclear Tension Regulates Progerin‐Induced Mechanosensitive Nuclear Wrinkling and Chromatin Remodeling

Advanced Science, EarlyView.
The premature aging‐related progerin leads to defective nuclear morphology and is associated with disrupted molecular coupling between the extranuclear cytoskeleton and lamin‐associated nuclear envelope. It is discovered that progerin expression reduces nuclear tension, forms nuclear wrinkling, and enhances chromatin dynamics, thereby regulating ...

On Constructive-Deductive Method For Plane Euclidean Geometry [PDF]

arXiv, 2019
Constructive-deductive method for plane Euclidean geometry is proposed and formalized within Coq Proof Assistant. This method includes both postulates that describe elementary constructions by idealized geometric tools (pencil, straightedge and compass), and axioms that describes properties of basic geometric figures (points, lines, circles and ...

1. Non-Euclidean Geometry [PDF]

Proceedings of the Royal Society of Edinburgh, 1880
When I had the honour of being asked by the Council of the Royal Society to give the following address, I chose the subject partly because it had been brought under the notice of the fellows by my predecessor, Professor Kelland. His memoir was written comparatively early in the history of the subject; and he seems to have been but little acquainted ...

Aromaticity‐Dependent Memristive Switching

Advanced Electronic Materials, EarlyView.
The article describes a resistive switching mechanism based on the creation of virtual filaments. Research consists of experimental and theoretical data supporting the theory that resistance of the memristor can be modulated by a redox‐induced aromaticity change of a working material.

Intensification of Alkaline Electrolyzer with Improved Two‑Phase Flow

Advanced Energy Materials, EarlyView.
Porous nickel‐type electrodes with low tortuosity are fabricated and their role in reducing the capillary pressure, bubble point, and ohmic resistance, which led to lower energy loss and higher current densities and efficiencies is investigated. The cell delivers a current density of 2 A cm−2 at ≈2 V.

Interpolation graph convolutional network for 3D point cloud analysis

International Journal of Intelligent Systems, Volume 37, Issue 12, Page 12283-12304, December 2022., 2022
Abstract The feature analysis of point clouds, a popular representation of three‐dimensional (3D) objects, is rising as a hot research topic nowadays. Point cloud data bear a sparse and unordered nature, making many commonly used feature extraction methods, for example, Convolutional Neural Networks (CNNs) inapplicable, while previous models suitable ...

Exploring female learners’ perceptions of learning geometry in mathematics

South African Journal of Education, 2020
In this article we explore female learners’ perceptions of learning Grade 11 geometry. Many learners have difficulty in learning geometry in mathematics, thus, teachers and researchers are constantly searching for reasons why learners have challenges ...

Euclidean distance geometry and applications [PDF]

arXiv, 2012
Euclidean distance geometry is the study of Euclidean geometry based on the concept of distance. This is useful in several applications where the input data consists of an incomplete set of distances, and the output is a set of points in Euclidean space that realizes the given distances.
