Tsallis holographic dark energy

Physics Letters B, 2018
Employing the modified entropy–area relation suggested by Tsallis and Cirto [1], and the holographic hypothesis, a new holographic dark energy (HDE) model is proposed.

Direct Electron Detection Electron Energy‐Loss Spectroscopy: Speeding Up 2D Analytical In Situ Transmission Electron Microscopy for Aluminum Alloys

Advanced Engineering Materials, EarlyView.
Scanning transmission electron microscopy imaging techniques are an essential tool to document dynamic developments, such as precipitation in aluminum alloys, during in situ heating experiments using transmission electron microscopy. However, in many cases, chemical information is required to interpret complex nanoscale processes.

Impact of Teleparallelism on Addressing Current Tensions and Exploring the GW Cosmology

The Astrophysical Journal
The H _0 and S _8 tensions highlight critical discrepancies in modern cosmology, challenging the standard Lambda cold dark matter model. The H _0 tension arises from conflicting measurements between local probes and early-Universe predictions. Similarly,

Coupled quintessence and the impossibility of an interaction: a dynamical analysis study

European Physical Journal C: Particles and Fields, 2017
We analyze the coupled quintessence in the light of the linear dynamical systems theory, with two different interactions: (1) proportional to the energy density of the dark energy and (2) proportional to the sum of the energy densities of the dark matter

Microstructural Evolution and Mechanical Property Degradation of Sn0.5Ag0.7Cu5Bi Solder Joints with High Indium Alloying

Advanced Engineering Materials, EarlyView.
This study identifies 12 wt% indium (In) as the optimal composition for Sn0.5Ag0.7Cu5Bi solder joints, achieving 87% ductile fracture and 81% suppression of intermetallic compound (IMC) growth versus 4 wt% In. High‐In alloys (15–17 wt%) show abnormal IMC thickening due to thermal activation.

Constraining Extended Teleparallel Gravity via Cosmography: A Model-independent Approach

The Astrophysical Journal
As a classical approach, the dynamics of the Universe, influenced by its dark components, are unveiled through prior modifications of Einstein’s equations.
