GWTC-2.1: Deep extended catalog of compact binary coalescences observed by LIGO and Virgo during the first half of the third observing run

“…We also expand the population of binaries with significantly asymmetric mass ratios reported in GWTC-2 by an additional two events (the mass ratio is less than 0.65 and 0.44 at 90% probability for GW190403_051519 and GW190917_114630 respectively), and find that two of the eight new events have effective inspiral spins χ eff > 0 (at 90% credibility), while no binary is consistent with χ eff < 0 at the same significance. …”

Laser-based 3D printing using bessel beams for tissue engineering applications by Liew, Andy Wen Loong

“…High resolution fibers down to 25 μm were printable using the BB technique, a significant improvement compared to conventional microfluidics and wet spinning techniques, and the capability to tune the fabricated fiber diameter based on mathematical models was also demonstrated. …”

Enlightening of the low-dimensional high-TC superconductivity: bond contraction and electron dual polarization [低维高温超导的启示: 键收缩与电子双重极化] by Sun, Chang Qing

“…Second, atomic undercoordination of the O-Cu chains and the O-Cu planes shortens and stiffens the local O-Cu bond and lengthens and weakens the O:Cup nonbonding interactions associated with further enhancement of the Cup dipoles polarization, this process is the same as the O:H-O bond relaxation and polarization occurred to the skins of water and ice. Last, the electronphonon interaction is realized by the undercoordination-induced bond relaxation and the dual polarization by lone pairs and bond contraction. …”

Strategies to modulate Amorphous Oxide Semiconductor properties for low temperature transparent transistors by Kulkarni, Mohit Rameshchandra

“…Such surface modifications can achieve a change in the carrier concentration by change in work function or shifting- pinning of the Fermi level, or additional field generated due to dipoles created at the surface. …”
