The Evolution of Community Energy in the UK [PDF]

open access: yes, 2018
This UKERC Working Paper seeks to understand the factors contributing to the emergence, growth and nature of community energy in the UK. It is based on a review of existing data and literature, and focuses on investigating the role of financing mechanisms and business models in the evolution of the community energy sector.

Probing dark energy evolution post-DESI 2024 [PDF]

open access: yesPhysics of the Dark Universe
We study the evidence for dark energy (DE) evolution at low redshift, using baryonic acoustic oscillations (BAOs) from the DESI Early Data Release, Pantheon+ Type Ia supernovae (SNe-Ia), and redshift space distortions (RSDs) to constrain cosmological ...

Mechanical characteristics and energy evolution law of sandstone failure process under post-peak cold and heat cycle

open access: yesMeikuang Anquan, 2023
In coal fire control, grouting/water extinguishing is often repeated for reasons such as re-ignition. The surrounding rock undergoes repeated heating and water cooling, resulting in strength reduction and damage, and collapse and cracks on the extended ...

BATSE Observations of Gamma-Ray Burst Spectra. IV. Time-Resolved High-Energy Spectroscopy [PDF]

open access: yes, 1997
We report on the temporal behavior of the high-energy power law continuum component of gamma-ray burst spectra with data obtained by the Burst and Transient Source Experiment.

Uniaxial compression failure and energy dissipation of marble specimens with flaws at the end surface

open access: yes工程科学学报, 2020
It is a fact that a large number of defects such as cracks, voids, inclusions, weak planes, and joint sets are generated within the rock mass during the process of rock formation because of geological-tectonic evolution.

Probing the outer edge of an accretion disk : a Her X-1 turn-on observed with RXTE [PDF]

open access: yes, 2005
We present the analysis of Rossi X-ray Timing Explorer (RXTE) observations of the turn-on phase of a 35 day cycle of the X-ray binary Her X-1. During the early phases of the turn-on, the energy spectrum is composed of X-rays scattered into the line of ...

Experimental study on triaxial mechanics and failure characteristics of shale in different brine environments

open access: yesYantu gongcheng xuebao, 2023
Shale is an ideal caprock for carbon dioxide sequestration projects in deep saline aquifers. Different brine solutions and confining pressures have a significant effect on the mechanical behaviors of caprock shale, which also affects the safety and ...

Zero energy resonance and the logarithmically slow decay of unstable multilevel systems [PDF]

open access: yes, 2006
The long time behavior of the reduced time evolution operator for unstable multilevel systems is studied based on the N-level Friedrichs model in the presence of a zero energy resonance.The latter means the divergence of the resolvent at zero energy ...

An investigation on the effect of high energy storage anchor on surrounding rock conditions [PDF]

open access: yesRoyal Society Open Science, 2020
High pre-tension bolt is an effective strata control technique and is the key to ensure the stability of anchorage and roadway. Based on the performances of high energy storage tension rock bolts in different rock properties, this study proposed a ...

Minimal Length, Friedmann Equations and Maximum Density [PDF]

open access: yes, 2014
Inspired by Jacobson's thermodynamic approach[gr-qc/9504004], Cai et al [hep-th/0501055,hep-th/0609128] have shown the emergence of Friedmann equations from the first law of thermodynamics.
