Resonant laser tunnelling [PDF]

open access: yesEuropean Physical Journal D 65, 563-570 (2011), 2012
We propose an experiment involving a gaussian laser tunneling through a twin barrier dielectric structure. Of particular interest are the conditions upon the incident angle for resonance to occur. We provide some numerical calculations for a particular choice of laser wave length and dielectric refractive index which confirm our expectations.

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Synergistic Effects of Cerium and Magnesium on Optimizing Electrical Conductivity and Mechanical Properties of AlSi3 Cast Alloys

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the impact of Ce and/or Mg on the electrical conductivity (EC) and mechanical properties of AlSi3 cast alloy. It highlights the synergistic effects of Ce and Mg on eutectic Si modification and Mg solute reduction in the Al matrix, resulting in the optimization of EC, strength, and ductility of the alloy.

Polarization field in a single-valley strongly-interacting 2D electron system [PDF]

open access: yesJETP Lett. 95, 570 (2012), 2012
The magnetic field of complete spin polarization is calculated in a disorderless single-valley strongly-interacting 2D electron system. In the metallic region above the Wigner-Mott transition, non-equilibrium spin states are predicted, which should give rise to hysteresis in the magnetization.
