Galactic Halo Wormhole Solutions in f(T) Gravity

Advances in High Energy Physics, 2014
The proposal of galactic halo region is based on the idea that dark halos contain some characteristics needed to support traversable wormhole solutions. We explore wormhole solutions in this region in the framework of generalized teleparallel gravity. We

Mapping Charge Interactions in Intrinsically Disordered Proteins

Advanced Science, EarlyView.
This study presents analytical models to predict intrachain distances in intrinsically disordered proteins (IDPs), accounting for charge patterning, salt concentration, and electrostatic effects. Validated against single‐molecule FRET data, a minimal‐parameter polymer model is identified that captures key interactions and chain dimensions. These models

Weighing the Galactic dark matter halo: a lower mass limit from the fastest halo star known

, 2010
The mass of the Galactic dark matter halo is under vivid discussion. A recent study by Xue et al. (2008, ApJ, 684, 1143) revised the Galactic halo mass downward by a factor of ~2 relative to previous work, based on the line-of-sight velocity distribution

Plasma Wave-particle Acceleration as the Origin of the Galactic Gamma-Ray Bubbles

The Astrophysical Journal
The “Fermi bubbles” are two giant gamma-ray emitting configurations in the form of bubbles that extend above and below the Galactic plane. They are characterized by a smooth surface, sharp edges, and an almost flat intensity distribution.

Alkylthienyl Side Groups in Conjugated Polymers Enable Localization of π Electron Density and Facilitate Efficient Hole Transfer

Advanced Science, EarlyView.
Resonance Raman spectroscopy is used in combination with other spectroscopic and morphology characterization techniques to unveil the mechanistic origin of the shift in synthetic strategy to alkylthienyl peripheral groups for high‐performing organic photovoltaics.

What Rogue Hydrogen Clouds Tell Us about Galactic Magnetic Fields

The Astrophysical Journal
Observations of the Milky Way and external galaxies support the idea that large-scale magnetic fields are concentrated in galactic disks, with halo magnetic fields at least an order of magnitude weaker.

Solid Harmonic Wavelet Bispectrum for Image Analysis

Advanced Science, EarlyView.
The Solid Harmonic Wavelet Bispectrum (SHWB), a rotation‐ and translation‐invariant descriptor that captures higher‐order (phase) correlations in signals, is introduced. Combining wavelet scattering, bispectral analysis, and group theory, SHWB achieves interpretable, data‐efficient representations and demonstrates competitive performance across texture,

Wafer‐Scale Room‐Temperature Processing of Lead‐Free Perovskites for Optoelectronic Applications

Advanced Science, EarlyView.
We present the first wafer‐scale, room‐temperature synthesis of lead‐free Cs3Sb2X9 (X = Br, I) perovskite films via solvent‐free magnetron sputtering. The resulting high‐performance photodetectors achieve benchmark responsivity, bandwidth, and detectivity, enabling scalable manufacturing for next‐generation optoelectronics.

The Microlensing and Halo Models of the Galaxy

, 1995
We investigated the dependence of the optical depth $\tau$ of the microlensing events on model parameters of the Galactic halo. We only consider Galactic mass models in which the rotation curve inside the Sun is compatible with the observation and LMC is

DAMA RESULTS: DARK MATTER IN THE GALACTIC HALO

Acta Polytechnica, 2013
Experimental efforts and theoretical developmens support that most of the Universe is Dark and a large fraction of it should be made of relic particles; many possibilities are open on their nature and interaction types.
