Thermal Decay of the Cosmological Constant into Black Holes [PDF]

open access: yesPhysical Review D, 2003
We show that the cosmological constant may be reduced by thermal production of membranes by the cosmological horizon, analogous to a particle ``going over the top of the potential barrier", rather than tunneling through it. The membranes are endowed with

Unruh thermal hadronization and the cosmological constant

open access: yesPhysics Letters B, 2018
We use black holes with a negative cosmological constant to investigate aspects of the freeze-out temperature for hadron production in high energy heavy-ion collisions.

Renormalisation Group Improved Thermal Coupling Constant In An External Field [PDF]

open access: green, 1998
Starting from renormalised Effective Lagrangian, in the presence of an external Chromo-Electric field at finite temperature, the expression for thermal coupling constant ($\alpha = (g^2)/(4 \pi)$) as a function of temperature and external field is ...

Numerical Simulation of the Effect of Temperature- dependent Acoustic and Thermal Parameters on the Focal Temperature and Thermal Lesion of Biological Tissue Irradiated by HIFU [PDF]

open access: yesIranian Journal of Medical Physics, 2023
Introduction: Accurate temperature and thermal lesion prediction is very important for high-intensity focused ultrasound (HIFU) in the treatment of tumors.

Modeling Thermal Developmental Trajectories and Thermal Requirements of the Ladybird Stethorus gilvifrons

open access: yesInsects, 2022
The development rate of the predatory ladybird, Stethorus gilvifrons (Mulsant), fed on Tetranychus urticae Koch, was determined at 15, 20, 25, 27, 30, 34, and 38 °C.

Temperature requirements for immature stages of Sunn Pest, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران
Sunn Pest, Eurygaster integriceps is a serious insect pest of wheat and barley throughout West and Central Asia. Effects of temperature on the development and survival of different stages of E. integriceps were studied.

Rugged constant-temperature thermal anemometer [PDF]

open access: yesReview of Scientific Instruments, 2016
Here we report a robust thermal anemometer which can be easily built. It was conceived to measure outdoor wind speeds and for airspeed monitoring in wind tunnels and other indoor uses. It works at a constant, low temperature of approximately 90 °C, so that an independent measurement of the air temperature is required to give a correct speed reading ...

Thermal perturbations from cosmological constant relaxation [PDF]

open access: yesPhysical Review D, 2022
We probe the cosmological consequences of a recently proposed class of solutions to the cosmological constant problem. In these models, the universe undergoes a long period of inflation followed by a contraction and a bounce that sets the stage for the hot big bang era.
