Stimulated Emission of Dark Matter Axion from Condensed Matter Excitations [PDF]
arXiv, 2016 We discuss a possible principle for detecting dark matter axions in galactic halos. If axions constitute a condensate in the Milky Way, stimulated emissions of the axions from a type of excitation in condensed matter can be detectable. We provide general mechanism for the dark matter emission, and, as a concrete example, an emission of dark matter ...

Advanced Materials Interfaces, EarlyView.CO2 laser ablation, a fast, inexpensive, and reproducible method, is used to create flexible elastomer molds with millimeter‐long cavities for the fabrication of dissolvable polymer needles. Made from PVP, these milli‐needles achieve ≈560 µm penetration into porcine skin, demonstrating their potential for effective transdermal drug delivery.

4D Printed Self‐Deploying Bio‐Based Scaffolds for the Regeneration of Endoluminal Tissue
Advanced Materials Technologies, EarlyView.A bilayer self‐deploying tubular C‐shaped scaffold, made of natural polymers and triggerable by humidity, is fabricated via 4D printing for the regeneration of gastro‐intestinal tissue. The choice of the materials and their spatial arrangement is guided by physical and biological evaluation, whereas the geometry of the structure is optimized through ...

Advanced Theory and Simulations, EarlyView.FreqD‐LBM simulates the oscillatory flow at the surface of a QCM‐D resonator in the presence of structured adsorbates. It derives shifts of frequency and bandwidth (equivalent to dissipation) on different overtones. Applications include rough surfaces, adsorbed rigid particles, adsorbed viscoelastic particles, spheres floating freely above the surface,

Advanced Theory and Simulations, EarlyView.Binding energy and electronic structure calculations are used to assess the ability of metal–organic framework (MOF)‐TiO2 composite materials to detect volatile organic compounds found in human breath. Electronic structure changes are measured by comparing density of states profiles using Wasserstein distances.

Bright soliton trains of trapped Bose-Einstein condensates [PDF]
arXiv, 2002 We variationally determine the dynamics of bright soliton trains composed of harmonically trapped Bose-Einstein condensates with attractive interatomic interactions. In particular, we obtain the interaction potential between two solitons. We also discuss the formation of soliton trains due to the quantum mechanical phase fluctuations of a one ...

Critical velocity in cylindrical Bose-Einstein condensates [PDF]
, 2000 We describe a dramatic decrease of the critical velocity in elongated cylindrical Bose-Einstein condensates which originates from the non-uniform character of the radial density profile. We discuss this mechanism with respect to recent measurements at MIT.

Advanced Science, EarlyView.The fusion peptide LR27‐modified thermosensitive nanodelivery system exhibits both hair cell targeting and inner ear penetrating properties. This system sustainably and effectively delivers PTH1‐34 to the inner ear of a hearing loss mouse model via the synergistic effects of multiple peptides, achieving satisfactory hearing protection through ...

An example of quantum control via Feshbach resonance in Bose-Einstein condensates [PDF]
arXiv, 2003 We present a simple example of quantum control in Bose-Einstein condensates via Feshbach resonance. By tuning an initially positive scattering length to zero, it is possible to generate oscillatory motion of the condensate that results from quantum interference.
