Describing pair production in inhomogeneous external fields with the Dirac-Heisenberg-Wigner formalism

open access: yesEPJ Web of Conferences, 2014
In this contribution we present results on pair production from vacuum in QED in case of inhomogeneous external electric fields. The central tool of our description is the relativistic one particle single-time Wigner-function, that describes the ...

Transitional Cell Carcinoma within a Portion of Inguinally Herniated Bladder

open access: yesCase Reports in Urology, 2013
Bladder herniation within the inguinal canal is a relatively uncommon finding. We report an even less-common occurrence of transitional cell carcinoma located within a portion of inguinally herniated bladder. Fewer than 20 reports exist in the literature

Registro en RCP pediátrica

open access: yesMetro Ciencia, 2021
El paro cardíaco en niños es un evento raro; sin embargo, aunque los resultados de la reanimación cardiopulmonar han mejorado significativamente en los últimos años la morbimortalidad sigue siendo elevada. A pesar del reconocimiento de la importancia de este evento, no existe un impulso generalizado para que se realicen estudios clínicos, revisiones y ...

Microstructure, Thermal Transport, and Dry‐Sliding Tribology of Powder‐Metallurgy Al7075 Composites Reinforced With Sol–Gel‐Derived ZnO–rGO Hybrid Nanoparticles

open access: yesAdvanced Engineering Materials, EarlyView.
Sol–gel‐derived ZnO–rGO hybrid nanoparticles enable Al7075 powder‐metallurgy composites to achieve concurrent gains in hardness and thermal conductivity while markedly lowering friction and wear. The hybrid architecture couples ZnO‐based load support with rGO‐assisted lamellar sliding and heat spreading, revealing a promising route toward lightweight ...

Chiral Phase Change Nanomaterials

open access: yesAdvanced Functional Materials, EarlyView.
This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...
