The role of natal kicks in forming asymmetric compact binary mergers [PDF]

open access: yesarXiv, 2023
In their most recent observing run, the LIGO-Virgo-KAGRA (LVK) Collaboration observed gravitational waves (GWs) from compact binary mergers with highly asymmetric mass ratios, including both binary black holes (BBHs) and neutron star--black holes (NSBHs).

A selective transformation of enals into chiral γ-amino alcohols. [PDF]

open access: yes, 2013
A one-pot synthesis of chiral amino alcohols from α,β-unsaturated aldehydes is reported which circumvents competitive 1,2- versus 1,4-boryl addition, by means of using a sterically hindered amine-derived imine.

Modeling Translation in Protein Synthesis with TASEP: A Tutorial and Recent Developments [PDF]

open access: yesJournal of Statistical Physics 2011, 2011
The phenomenon of protein synthesis has been modeled in terms of totally asymmetric simple exclusion processes (TASEP) since 1968. In this article, we provide a tutorial of the biological and mathematical aspects of this approach. We also summarize several new results, concerned with limited resources in the cell and simple estimates for the current ...

Sharpless Asymmetric Dihydroxylation: An Impressive Gadget for the Synthesis of Natural Products: A Review

open access: yesMolecules, 2023
Sharpless asymmetric dihydroxylation is an important reaction in the enantioselective synthesis of chiral vicinal diols that involves the treatment of alkene with osmium tetroxide along with optically active quinine ligand.

Pelvic Organ Prolapse-Associated Cystitis [PDF]

open access: yes, 2014
This thesis concerns the construction of 2,3-dihydro-4r7-pyran-4-one and 3(2//)-furanone ring systems by mercury(II)-catalysed reactions, or by more conventional cyclisations, and the potential of such reactions for the synthesis of natural products ...

Molecular docking investigation of cytotoxic phenanthrene derivatives

open access: yesComptes Rendus. Chimie, 2020
Our previous experimental work indicated that the presence of ester functionality in phenanthrene derivatives D-1 and D-2 leads to potent cytotoxicity against the Caco-2 cell line. The present work is based on th-is experimental result.

Asymmetric Bilateral Motion Estimation for Video Frame Interpolation [PDF]

open access: yesarXiv, 2021
We propose a novel video frame interpolation algorithm based on asymmetric bilateral motion estimation (ABME), which synthesizes an intermediate frame between two input frames. First, we predict symmetric bilateral motion fields to interpolate an anchor frame.

Synergistic Pd/Cu catalysis for stereoselective allylation of vinylethylene carbonates with glycine iminoesters: Enantioselective access to diverse trisubstituted allylic amino acid derivatives

open access: yesGreen Synthesis and Catalysis, 2021
We reported a synergistic Pd/Cu catalyzed enantioselective decarboxylative allylation of vinylethylene carbonates with glycine iminoesters, which provides facile access to non-proteinogenic diverse trisubstituted allylic amino acid derivatives in high ...
