Perturbative spacetimes from Yang-Mills theory

Abstract The double copy relates scattering amplitudes in gauge and gravity theories. In this paper, we expand the scope of the double copy to construct spacetime metrics through a systematic perturbative expansion. The perturbative procedu...

Mechanism for rapid growth of organic–inorganic halide perovskite crystals

Single crystals of lead halide perovskites exhibit good optoelectronic properties. Here, the authors study and deduce the mechanism for crystallisation and show how controlling dissolution of colloids through varying the acidity and tempera...

Comparison between GEANT4 and MCNP for well logging applications

MCNP and GEANT4 are two reference Monte Carlo nuclear simulators, MCNP being the standard in the Oil & Gas nuclear logging industry. While performing a simulation benchmark of these two software for the purpose of “Cased Hole” wellbore eval...

Baryogenesis and first-order QCD transition with gravitational waves from a large lepton asymmetry

Abstract A large primordial lepton asymmetry can lead to successful baryogenesis by preventing the restoration of electroweak symmetry at high temperatures, thereby suppressing the sphaleron rate. This asymmetry can also lead to a first-ord...

Enhanced conformal BMS3 symmetries

Abstract An enhanced version of the conformal BMS3 algebra is presented. It is shown to emerge from the asymptotic structure of an extension of conformal gravity in 3D by Pope and Townsend that consistently accommodates an additional spin-2...

Aspects of non-minimally coupled curvature with power laws

Abstract We consider a class of theories containing power-law terms in both the Ricci scalar and a scalar field, including their non-minimal couplings. As a first step, we systematically classify all non-trivial cases with a propagating sca...

Graviton condensate stars and its gravitational echoes

We construct the exact stellar configurations that contain an ordinary perfect-fluid matter that interacts minimally with a condensate of gravitons with distinct pressure conditions on the surface. We propose vanishing transverse pressure o...

Visionary figures in the field of electrochemistry who revolutionized voltammetry

Understanding energetics and electron behavior has been pivotal in elucidating numerous fundamental phenomena, including electricity, corrosion, respiration, energy generation in biological systems, intermolecular interactions within living...

Correction : Low carbon futures: assessing the status of decarbonisation efforts at universities within a 2050 perspective

Corporate Social Responsibility through Collaboration in the Supply Chain: Insights into a More Sustainable Economy

Purpose The purpose of this study is to explore and analyze corporate social responsibility (CSR) as a helpful tool in solving significant societal concerns in countries where there is a greater desire for social and economic growth, such...

Securing Electric Vehicle Performance: Machine Learning-Driven Fault Detection and Classification

Electric vehicles (EVs) are commonly recognized as environmentally friendly modes of transportation. They function by converting electrical energy into mechanical energy using different types of motors, which aligns with the sustainable pri...

Videoconferencing fatigue and online student engagement among Filipino senior high school students: A mixed methods study

IntroductionThe ubiquity of online classes during the COVID-19 pandemic induced the widespread use of videoconferencing applications. However, the prolonged use of these applications can lead to videoconferencing fatigue. Drawing from an on...

A Comprehensive Dataset of Residential Air Conditioning Prevalence in the Continental United States

Abstract This dataset presents the most comprehensive estimate of residential air conditioning (AC) prevalence across the continental United States. Using property-level data for over 103 million housing units from the Dewey database, we im...

Untargeted metabolomic profiling of Pseudocnella sykion from KwaZulu-Natal, South Africa using 1H-NMR and UPLC-QTOF-HR-MS

IntroductionSea cucumbers are ecologically and economically significant marine invertebrates, yet the metabolic diversity and bioactive potential of noncommercialized, endemic species remains poorly understood.MethodsThis study presents the...

Brassinosteroid-lipid membrane interaction under low and high temperature stress in model systems

Abstract Background In earlier studies [1], we indicated that applying brassinosteroids (BRs) to lipids that had been isolated from plants altered the physicochemical properties of the monolayers. A continuation of these dependencies using ...

Heavy top quark mass in the minimal universal seesaw model

We study the hierarchy between MT , vL, and vR, the relevant energy scales of the Minimal Universal Seesaw Model (MUSM), where the two lightest quark families remain massless at tree level. We also predict the heavy top quark mass, mt′ . We...

Low cloud response to aerosol‐radiation‐cloud interactions: Idealized WRF numerical experiments for EUREC4A project

Abstract Aerosols significantly affect cloud microphysics and energy budget in different ways. The contribution of the direct, semi‐direct, and indirect effects of aerosols on radiation are here investigated over the North Atlantic tropical...

Impact of solvents on doctor blade coatings and bathocuproine cathode interlayer for large-area organic solar cell modules

Efforts to commercialize organic solar cells (OSCs) by developing roll-to-roll compatible modules have encountered challenges in optimizing printing processes to attain laboratory-level performance in fully printable OSC architectures. In t...
