Coupled Disk-star Evolution in Galactic Nuclei and the Lifetimes of QPE Sources
The Astrophysical JournalA modest fraction of the stars in galactic nuclei fed toward the central supermassive black hole (SMBH) approach on low-eccentricity orbits driven by gravitational-wave radiation (extreme mass ratio inspiral (EMRI)).

Blue Straggler Formation in Clusters
, 2010 Blue stragglers are thought to be formed from the merger or coalescence of two stars, but the details of their formation in clusters has been difficult to disentangle.

Accretion flares from stellar collisions in galactic nuclei
Astronomy & AstrophysicsContext. The strong tidal force in a supermassive black hole’s (SMBH) vicinity, coupled with a higher stellar density at the center of a galaxy, make it an ideal location to study the interaction between stars and black holes. Two stars moving near the SMBH could collide at a very high speed, which can result in a high energy flare.

Advanced Functional Materials, EarlyView.Hybrid nanogenerator (HNG) based on a zinc‐metal‐organic framework‐loaded fibrous film integrated with a hierarchically modified nylon film having micropatterns and micropores is fabricated via an electrospinning technique, and its electrical properties are optimized. The HNGs are incorporated into wearable garments and automobile systems for practical

The Astrophysical JournalThe LMC’s stellar bar is offset from the outer disk center, tilted from the disk plane, and does not drive gas inflows. These properties are atypical of bars in gas-rich galaxies, yet the LMC bar’s strength and radius are similar to typical barred ...

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Advanced Functional Materials, EarlyView.Most matter is nominally frozen in the polar regions or space, and liquid crystal materials are no exception. Consequently, soft actuators, including liquid crystal elastomers (LCEs), are inoperative under such extreme cold in response to stimuli, as their motion relies on mechanical deformation.

“Three-integral”, collision-free statistical mechanics and stellar systems [PDF]
Symposium - International Astronomical Union, 1979 In a recent paper, Innanen and Papp (1977) have introduced and discussed the behaviour of a function they called the “super angular momentum,” ht2. This quantity, although not formally an integral of motion in the classical definition, is nevertheless a straightforward generalization of the classical total angular momentum.

Defect Analysis of the β– to γ–Ga2O3 Phase Transition
Advanced Functional Materials, EarlyView.The role of defects at all the relevant stages of the β$\beta$‐ to γ$\gamma$‐Ga2O3 polymorph transition is investigated using a multi method approach. The positron annihilation spectroscopy based results show that the defect density decreases after the transition, and that changes in defect configuration within the γ phase occur with increasing ...
