Periodic Cosmological Evolutions of Equation of State for Dark Energy

, 2012
We demonstrate two periodic or quasi-periodic generalizations of the Chaplygin gas (CG) type models to explain the origins of dark energy as well as dark matter by using the Weierstrass $\wp(t)$, $\sigma(t)$ and $\zeta(t)$ functions with two periods ...

Transcriptomic Profiling of Canine Mammary Tumours Reveals Significant Heterogeneity Between and Within Histological Classes

Veterinary and Comparative Oncology, EarlyView.
ABSTRACT This study presents a comprehensive transcriptomic analysis of 128 canine mammary tumours (CMTs), aiming to characterize their molecular landscape. Differential gene expression analysis (DGE), gene set enrichment analysis (GSEA) and clustering based on the human PAM50 gene panel were applied to explore molecular differences between the ...

Type-II QC-LDPC Codes From Multiplicative Subgroup of Prime Field

IEEE Access, 2020
A quasi-cyclic (QC) low-density parity-check (LDPC) code is called type-II, if the maximum weight over all circulants appearing in the parity-check matrix has the value of two. On the basis of multiplicative subgroup analysis for the prime field, a novel

A Class of Quantum LDPC Codes Constructed From Finite Geometries

, 2008
Low-density parity check (LDPC) codes are a significant class of classical codes with many applications. Several good LDPC codes have been constructed using random, algebraic, and finite geometries approaches, with containing cycles of length at least ...

Quasivoids in Polydisperse Glassy Systems With Atomistic PEL Exploration and Iso‐Configuration Method

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Understanding the microscopic relaxation mechanisms in amorphous solids remains a fundamental challenge. A theoretical framework posits that dynamics are mediated by quasivoids: transient, localized quasi‐particles that are the amorphous analogue of crystalline vacancies.

Surface X‐Ray Diffraction Study of Ag‐Decorated Cu(100) Under Electrochemical Reduction of CO2

ChemElectroChem, Volume 13, Issue 9, 5 May 2026.
In situ surface X‐ray diffraction reveals that the Ag‐decorated Cu(100) electrode surface restructures dynamically during initial CO2 electroreduction, driven by the formation of CO intermediates. The interfacial order also evolves with applied potential. These catalyst structural changes are highly reversible during fast potential scan but become only

Tanner $(J,L)$ Quasi-Cyclic LDPC Codes: Girth Analysis and Derived Codes

IEEE Access, 2019
Girth plays an important role in the design of low-density parity-check (LDPC) codes. Motivated by the works on the girth of some classes of Tanner quasi-cyclic (QC) LDPC codes, e.g., Tanner (3, 5), (3, 7), (3, 11), and (5, 7) codes, we, in this paper ...

Deterministic Entanglement as a Prerequisite for Scalable Quantum Photonic Resource State Generation

Advanced Quantum Technologies, Volume 9, Issue 5, May 2026.
Scalable photonic quantum computing requires entanglement generated deterministically. Simple combinatorics shows that probabilistic fusion causes exponential overheads, while 1D entangled‑state sources offer orders‑of‑magnitude higher success probabilities than Bell pairs or single photons.

Mapping Subsea Permafrost Distribution in the Canadian Beaufort Sea With Marine Seismic and Deep Learning

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Subsea permafrost is widespread across the polar continental shelf, and mapping its distribution is crucial for assessing the possible impact of its degradation in response to global warming. While seismic techniques have been useful in determining the lateral extent of subsea permafrost in the Canadian Beaufort Sea, are limited when it comes ...

Classification of the Atmospheric Boundary Layer Based on Turbulent Kinetic Energy Budget Terms Using Machine‐Learning Methods

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The atmospheric boundary layer (ABL) controls surface‐atmosphere exchanges, yet accurately capturing its full complexity, particularly the dynamically evolving nature of turbulence across diverse weather conditions, remains a formidable challenge for traditional classification methods.
