An Extensive Analysis of Tsallis Statistics: π±, K± Mesons, and pp¯ Baryon in Inelastic pp Collisions

open access: yesAtoms
This study explores the inelastic doubly differential transverse momentum spectra of the primary charged particles, (π++π−), (K++K−) and (pp¯), as a function of observables associated with underlying event (UE) at s=13TeV.

On the Blackbody Spectrum of Kilonovae

open access: yesThe Astrophysical Journal, 2023
The early spectra of the kilonova AT2017gfo have a remarkably smooth blackbody continuum, which reveals information on the thermal properties and radioactive heating within the ejecta.

Calibration of a single‐diode performance model without a short‐circuit temperature coefficient

open access: yesEnergy Science & Engineering, 2018
We calibrate the seven parameters of a single‐diode model (SDM) for photovoltaic device performance using current‐voltage (I‐V) curves measured under controlled laboratory conditions over a matrix of nominal temperature and irradiance combinations.

Empirical metallicity-dependent calibrations of effective temperature against colours for dwarfs and giants based on interferometric data [PDF]

open access: yes, 2015
We present empirical metallicity-dependent calibrations of effective temperature against colours for dwarfs of luminosity classes IV and V and for giants of luminosity classes II and III, based on a collection from the literature of about two hundred ...

Self-propelled particle in an external potential: existence of an effective temperature. [PDF]

open access: yesPhysical review. E, Statistical, nonlinear, and soft matter physics, 2014
We study a stationary state of a single self-propelled, athermal particle in linear and quadratic external potentials. The self-propulsion is modeled as a fluctuating internal driving force evolving according to the Ornstein-Uhlenbeck process ...

Results of a phenological study of the tree layer of a mixed stand in the region of the Drahanská vrchovina Upland

open access: yesJournal of Forest Science, 2008
The paper presents the results of phenological studies of Norway spruce (Picea abies[L.] Karst.), European beech (Fagus sylvatica L.) and European larch (Larix decidua Mill.) in a mixed stand in 2004 to 2007. The results show different onset and duration

A programmable and skin temperature–activated electromechanical synergistic dressing for effective wound healing

open access: yesScience Advances, 2022
Mechanical regulation and electric stimulation hold great promise in skin tissue engineering for manipulating wound healing. However, the complexity of equipment operation and stimulation implementation remains an ongoing challenge in clinical ...

Moving in the Dark: Enlightening the Spatial Population Ecology of European Cave Salamanders

open access: yesPopulation Ecology, EarlyView.
We assessed individual interactions, movement ecology and activity patterns of a subterranean population of Speleomantes strinatii, applying spatial capture–recapture modeling to a photographic dataset of 104 individuals. ABSTRACT Space use and movement are fundamental aspects of organisms' ecology, mirroring individual fitness, behavior, and life ...

Influences of sowing date and climate conditions on the phenological phases of different maize hybrids [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade)
The experiment was set up during 2016 and 2017 in the Leskovac area on an alluvial soil. For research purposes, the duration of certain phenological phases, the entire vegetation period of 6 maize hybrids, and three FAO maturity groups (400-600) were ...

Speciation Through the Lens of Population Dynamics: A Theoretical Primer on How Small and Large Populations Diverge

open access: yesPopulation Ecology, EarlyView.
Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size
