New perturbative solutions of the Kerr-Newman dilatonic black hole field equations [PDF]

, 1996
This work describes new perturbative solutions to the classical, four-dimensional Kerr--Newman dilaton black hole field equations. Our solutions do not require the black hole to be slowly rotating.

Decarbonised District Heat, Electricity and Synthetic Renewable Gas in Wind- and Solar-Based District Energy Systems

Journal of Sustainable Development of Energy, Water and Environment Systems, 2021
Low availability of sustainable biomass prevents transition of district heating in Europe away from fossil fuels. The need for sustainable fuels stems from current energy generation structure, which mainly relies on centralised combined heat and power ...

Protein Sectors: Statistical Coupling Analysis versus Conservation

PLOS Computational Biology, 2015
Statistical coupling analysis (SCA) is a method for analyzing multiple sequence alignments that was used to identify groups of coevolving residues termed "sectors". The method applies spectral analysis to a matrix obtained by combining correlation information with sequence conservation.

Axion Dissipation Through the Mixing of Goldstone Bosons [PDF]

, 1994
By coupling axions strongly to a hidden sector, the energy density in coherent axions may be converted to radiative degrees of freedom, alleviating the ``axion energy crisis''.

The Dielectric Skyrme model [PDF]

, 2020
We consider a version of the Skyrme model where both the kinetic term and the Skyrme term are multiplied by field-dependent coupling functions. For suitable choices, this "dielectric Skyrme model" has static solutions saturating the pertinent topological

Higher twisted sector couplings of orbifolds

Nuclear Physics B, 1993
We derive the basic correlation functions of twist fields coming from arbitrary twisted sectors in symmetric $Z_N$ orbifold conformal field theories, keeping all the admissible marginal perturbations, in particular those corresponding to the antisymmetric tensor background field.

Modeling the energy transition: Multiobjective optimization of green hydrogen deployment strategies [PDF]

E3S Web of Conferences
The energy transition is a complex concept that requires progressively addressing various technical, environmental, social, and political issues. Green hydrogen is recognized as a clean fuel to support the energy transition worldwide. This study presents

Dark matter from unification [PDF]

, 2013
We consider a minimal extension of the Standard Model (SM), which leads to unification of the SM coupling constants, breaks electroweak symmetry dynamically by a new strongly coupled sector and leads to novel dark matter candidates.

Cosmological perturbations in massive gravity with doubly coupled matter [PDF]

, 2015
We investigate the cosmological perturbations around FLRW solutions to non- linear massive gravity with a new effective coupling to matter proposed recently.
