Euclidean analysis of the entropy functional formalism

open access: yes, 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.

A Novel Dual‐Network Approach for Real‐Time Liveweight Estimation in Precision Livestock Management

open access: yesAdvanced Science, EarlyView.
A novel dual‐network framework is proposed for real‐time, non‐contact liveweight estimation of pigs. By extracting contour information instead of segmented images, the method achieves high accuracy (R2 = 0.993) and an exceptional speed of 1131.6 FPS. This approach enhances automation in livestock farming, providing a scalable and efficient solution for

The use of Van Hiele’s geometric thinking model to interpret Grade 12 learners’ learning difficulties in Euclidean Geometry

open access: yesPerspectives in Education
The 21st-century mathematics classrooms should equip learners with well-grounded knowledge and thinking skills pertaining to geometry. However, Euclidean geometry remains one of the challenging, if not the most difficult topic for many learners.

Hyperbolic matrix factorization improves prediction of drug-target associations

open access: yesScientific Reports, 2023
Past research in computational systems biology has focused more on the development and applications of advanced statistical and numerical optimization techniques and much less on understanding the geometry of the biological space.

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

open access: yesAdvanced 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 ...

A remark on Chapple-Euler Theorem in non Euclidean geometry [PDF]

open access: yesarXiv, 2020
In non-Euclidean geometry, there are several known correspondings to Chapple-Euler Theorem. This remark shows that those results yield expressions corredponding to the well-known formula $d=\sqrt{R(R-2r)}$.

On the non-generic Tzitzeica-Johnson's Configuration

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2012
Working in the context of Hilbert's axiomatic system, we prove that the Tzitzeica-Johnson configuration has sense in neutral geometry. The elements of a Tzitzeica-Johnson configuration allow us to analyse the Euclidean or the non-Euclidean character of ...

Osculating surfaces of curves on surfaces

open access: yesLietuvos Matematikos Rinkinys, 2020
Oosculating sphere have been studied in classical differential geometry [1]. In this article the osculating surfaces of higher order of space curves on surfaces in Euclidean space is considered.

Stringy Horizons

open access: yes, 2015
We argue that classical $(\alpha')$ effects qualitatively modify the structure of Euclidean black hole horizons in string theory. While low energy modes experience the geometry familiar from general relativity, high energy ones see a rather different ...

Chiral Amplification and Regulation: Design and Applications of Circularly Polarized Luminescence‐Active Materials Derived From Macrocyclic Compounds

open access: yesAggregate, EarlyView.
The graphical abstract highlights the key concepts of this review, including chiral transfer and amplification mechanisms, macrocyclic compounds, circularly polarized luminescence (CPL) applications, chiral sensing, asymmetric catalysis, and stimuli‐responsive applications.
