Investigating the role of a conserved hydrophobic pocket of gp41 in the anti‐HIV activity of fusion inhibitors

open access: yesProtein Science, Volume 35, Issue 6, June 2026.
Abstract Membrane fusion between HIV and host cells requires interaction between the N‐terminal and C‐terminal repeat regions (NHR and CHR) of the gp41 envelope subunit. A deep hydrophobic pocket (HP) on the surface of NHR is considered crucial in this interaction.

Tunable inertia of chiral magnetic domain walls

open access: yesNature Communications, 2016
The controlled motion of magnetic domain walls in nanowire conduits forms the basis of emerging memory and information processing devices. Here, the authors report a pulse-length dependent quasi-static velocity of current-driven chiral domain walls ...

Fate of false vacua in holographic first-order phase transitions

open access: yesJournal of High Energy Physics, 2020
Using the holographic correspondence as a tool, we study the dynamics of first-order phase transitions in strongly coupled gauge theories at finite temperature.

Permutation entropy-based characterization of speckle patterns generated by semiconductor laser light

open access: yesAPL Photonics, 2023
Semiconductor lasers with optical feedback are stochastic nonlinear systems that can display complex dynamics and abrupt changes when their operation conditions change.

Attractive and repulsive contributions of medium fluctuations to nuclear superfluidity

open access: yes, 2005
Oscillations of mainly surface character (S=0 modes) give rise, in atomic nuclei, to an attractive (induced) pairing interaction, while spin (S=1) modes of mainly volume character generate a repulsive interaction, the net effect being an attraction which

The influence of magnetic field geometry on magnetars X-ray spectra [PDF]

open access: yes, 2011
Nowadays, the analysis of the X-ray spectra of magnetically powered neutron stars or magnetars is one of the most valuable tools to gain insight into the physical processes occurring in their interiors and magnetospheres.

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

open access: yesArchaeometry, Volume 68, Issue 3, Page 317-329, June 2026.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

The final phase of inspiral of neutron stars: realistic equations of state [PDF]

open access: yes, 2007
Coalescing compact star binaries are expected to be among the strongest sources of gravitational radiation to be seen by laser interferometers. We present calculations of the final phase of inspiral of equal mass irrotational neutron star binaries and ...

Assessing the Role of Tropical Cyclones on Drought Characteristics in the Hurricane Region of the Americas Between 1983 and 2024

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Droughts and tropical cyclones (TCs) are among the deadliest and costliest natural hazards and are expected to intensify in the twenty‐first century due to anthropogenic climate change. The Hurricane Region of the Americas (HRA), an area frequently affected by TCs and droughts, is home to some of the most vulnerable countries to these hazards ...

Time domain study of frequency-power correlation in spin-torque oscillators

open access: yes, 2010
This paper describes a numerical experiment, based on full micromagnetic simulations of current-driven magnetization dynamics in nanoscale spin valves, to identify the origins of spectral linewidth broadening in spin torque oscillators.
