Horizons of semiclassical black holes are cold [PDF]
, 2014 We calculate, using our recently proposed semiclassical framework, the quantum state of the Hawking pairs that are produced during the evaporation of a black hole (BH). Our framework adheres to the standard rules of quantum mechanics and incorporates the

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.This paper presents a new transmission line (TL) and power divider/combiner (PDC) design using an oversized air‐filled substrate‐integrated waveguide (OS‐AFSIW). Our approach enhances the average power handling capability and reduces conductor loss. This paper focuses on designing a balanced‐delta‐port magic‐T PDC configuration within the OS‐AFSIW that

Gamma-ray bursters as sources of cosmic rays [PDF]
, 1995 The little we do know of the physical conditions in gamma-ray bursters makes them conducive to the acceleration of high-energy cosmic rays, especially if they are at cosmological distances.

steel research international, Volume 95, Issue 11, November 2024.The accuracy of computational models depends on uncertainty of the input data. This work conducts a sensitivity analysis of the CON1D model of solidification heat transfer in a steel continuous slab‐casting mold. Results identify the parameters which are critical to defect‐relevant outputs: mold heat flux, shell thickness, surface temperature, and mold

Precipitation Extremes and Their Modulation by Convective Organization in RCEMIP
Journal of Advances in Modeling Earth Systems, Volume 16, Issue 11, November 2024.Abstract We examine the influence of convective organization on extreme tropical precipitation events using model simulation data from the Radiative‐Convective Equilibrium Model Intercomparison Project (RCEMIP). At a given SST, simulations with convective organization have more intense precipitation extremes than those without it at all scales ...

IET Microwaves, Antennas &Propagation, Volume 18, Issue 10, Page 779-790, October 2024.A new sled‐power divider/combiner (PDC) based on an oversized substrate‐integrated waveguide (OS‐SIW) is analysed and designed for improving the power handling capability. The measured results of the fabricated PDC showcase a range of desirable features.

Medical perspectives on Israeli children after their release from captivity – A retrospective study
Acta Paediatrica, Volume 113, Issue 10, Page 2259-2265, October 2024.Abstract Aim Following the Hamas terror attack on Israeli towns on October 2023, 250 individuals were taken into captivity. On November–December 2023, during the cease‐fire deal, 26 women and children were released. This study is the first to describe the physical and behavioural findings in children and their mothers in the immediate phase of ...
