Novel vacuum conditions in inflationary collapse models

open access: yesPhysics Letters B, 2017
Within the framework of inflationary models that incorporate a spontaneous reduction of the wave function for the emergence of the seeds of cosmic structure, we study the effects on the primordial scalar power spectrum by choosing a novel initial quantum

CondensNet: enabling stable long-term climate simulations via hybrid deep learning models with adaptive physical constraints

open access: yesnpj Climate and Atmospheric Science
Accurate and efficient climate simulations are crucial for understanding Earth’s evolving climate. However, current general circulation models (GCMs) face challenges in capturing unresolved physical processes, such as cloud and convection.

Decentralized event-based leader-following consensus for a group of two-wheeled self-balancing robots

open access: yesRevista Iberoamericana de Automática e Informática Industrial RIAI, 2019
This paper deals with the development of a decentralized event-based control strategy applied to the leader-following consensus problem of a group of two-wheeled self-balancing robots so called mobile inverted pendulum (MIP).

A Fast Interlock Detection System for High-Power Switch Protection

open access: yes, 2015
Fast pulsed kicker magnet systems are powered by high-voltage and high-current pulse generators with adjustable pulse length and amplitude. To deliver this power, fast high-voltage switches such as thyratrons and GTOs are used to control the fast ...

Generative Convective Parametrization of a Dry Atmospheric Boundary Layer

open access: yesJournal of Advances in Modeling Earth Systems
Turbulence parametrizations will remain a necessary building block in kilometer‐scale Earth system models. In convective boundary layers, where the mean vertical gradients of conserved properties such as potential temperature and moisture are ...

One-loop renormalization of the type-I seesaw model in the modified minimal-subtraction scheme

open access: yesNuclear Physics B
Extending the Standard Model (SM) with three right-handed neutrinos, the type-I seesaw model serves as the simplest and most natural scenario to successfully explain both tiny neutrino masses and the baryon number asymmetry in the Universe. In this paper,

Optimization of an elastic network augmented coarse grained model to study CCMV capsid deformation. [PDF]

open access: yesPLoS ONE, 2013
The major protective coat of most viruses is a highly symmetric protein capsid that forms spontaneously from many copies of identical proteins. Structural and mechanical properties of such capsids, as well as their self-assembly process, have been ...

GENRE PARAMETRIZATION OF RECEIPT IN THE MIDDLE 18 th CENTURY (WITH REFERENCE TO “MIKHAILOVSKY STANITSA ATAMAN” ARCHIVE)

open access: yesВестник Волгоградского государственного университета: Серия 2. Языкознание, 2020
The relevance of the study is determined by the need to create linguistic corpora of historical sources – the acts and other documents of limited accessibility, which are stored in regional archives.
