Dynamical Study of Heat Transport Properties of Porous Silicon

Medžiagotyra, 2015
A new technique to determine thermal conductivity of porous silicon is proposed. Transient thermoelectric voltage is measured after a pulsed laser irradiation, and knowledge of the voltage decay time constant and porosity of the structure gives the value

Green functions and Martin compactification for killed random walks related to SU(3) [PDF]

, 2010
We consider the random walks killed at the boundary of the quarter plane, with homogeneous non-zero jump probabilities to the eight nearest neighbors and drift zero in the interior, and which admit a positive harmonic polynomial of degree three.

On the bicrossproduct structures for the ${\cal U}_\lambda(iso_{\omega_2... \omega_N}(N))$ family of algebras

, 1998
It is shown that the family of deformed algebras ${\cal U}_\lambda(iso_{\omega_2... \omega_N}(N))$ has a different bicrossproduct structure for each $\omega_a=0$ in analogy to the undeformed case.Comment: Latex2e file.

Genomic Evidence for Dual Introductions, Limited Gene Flow and Niche Preferences in the Invasive Wasp Vespula germanica in South Africa

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Biological invasions are major drivers of recent biodiversity changes, yet the genetic structure and ecological mechanisms underlying invasion dynamics remain poorly resolved in invasive social insects. In South Africa, the European wasp Vespula germanica (Hymenoptera: Vespidae), introduced in the 1970s, has spread remarkably more slowly than ...

Time-resolved Photoluminescence Characterisation of GaAs/AlxGa1–xAs Structures Designed for Microwave and Terahertz Detectors

Medžiagotyra, 2014
The time-resolved photoluminescence of donor Si-doped GaAs/AlxGa1-xAs (x = 0.3 0.25, 0.2, 0.1) structures designed for microwave and terahertz detectors have been investigated at T = 3.6 K temperature.

Casimir-Polder potential and transition rate in resonating cylindrical cavities

, 2010
We consider the Casimir-Polder potential of particles placed inside a metallic cylindrical cavity at finite temperatures, taking account of thermal non-equilibrium effects.

Integration of Laser‐Patterned Photonic Crystals in Si Solar Cells

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
Photonic crystal textures are integrated into silicon solar cells using laser‐patterned alumina masks and plasma etching. An isotropic defect‐removal process preserves surface passivation and optical quality, enabling 23.1% efficiency. This scalable process with periodically anchored masks and Bessel‐beam patterning marks an important step toward ...

Complications in Endoscopic Sinus Surgery: A TriNetX Network Analysis

International Forum of Allergy &Rhinology, Volume 15, Issue 12, Page 1393-1404, December 2025.
ABSTRACT Background The potential complications of endoscopic sinus surgery (ESS) remain a critical surgical consideration. This study aims to examine complication rates and identify trends in ESS‐related complications. Methods The TriNetX network was queried for patients undergoing ESS between 2005 and 2024.
