Density Functional Theory Transition-State Modeling for the Prediction of Ames Mutagenicity in 1,4 Michael Acceptors
Assessing the safety of new chemicals, without introducing the need for animal testing, is a task of great importance. The Ames test, a widely used bioassay to assess mutagenicity, can be an expensive, wasteful process with...
Rigid analytic quantum groups and quantum Arens-Michael envelopes
Nicolas Dupré
Aug 19, 2019
We introduce a rigid analytification of the quantized coordinate algebra of a semisimple algebraic group and a quantized Arens-Michael envelope of the enveloping algebra of the corresponding Lie algebra, working over a...

Organocatalytic Enantioselective Sulfa-Michael Additions to α,β-Unsaturated Diazoketones
Patricia B Momo, Eduardo F Mizobuchi, Radell Echemendía, Isabel Baddeley, Matthew N Grayson, Antonio C B Burtoloso
Mar 04, 2022
Enantioselective sulfa-Michael additions to α,β unsaturated diazocarbonyl compounds have been developed. Quinine-derived squaramide was found to be the best catalyst to promote C-S bond formation in a highly stereoselective...
A long postreproductive life span is a shared trait among genetically distinct killer whale populations
Mia Lybkær Kronborg Nielsen, Samuel Ellis, Jared R. Towers, Thomas Doniol‐Valcroze, Daniel W. Franks, Michael A. Cant, Michael N. Weiss, Rufus A. Johnstone, Kenneth C., III Balcomb, David K. Ellifrit, Darren P. Croft

Abstract: The extended female postreproductive life span found in humans and some toothed whales remains an evolutionary puzzle. Theory predicts demographic patterns resulting in increased female relatedness with age (kinship...

Eliminating Transition State Calculations for Faster and More Accurate Reactivity Prediction in Sulfa-Michael Additions Relevant to Human Health and the Environment
Fast and accurate computational approaches to predicting reactivity in sulfa-Michael additions are required for high-throughput screening in toxicology (e.g., predicting excess aquatic toxicity and skin sensitization), chemical...
Reproductive Conflict and the Evolution of Menopause in Killer Whales.
Darren P Croft, Rufus A Johnstone, Samuel Ellis, Stuart Nattrass, Daniel W Franks, Lauren JN Brent, Sonia Mazzi, Kenneth C Balcomb, John KB Ford, Michael A Cant
Sep 02, 2019
Why females of some species cease ovulation prior to the end of their natural lifespan is a long-standing evolutionary puzzle [1-4]. The fitness benefits of post-reproductive helping could in principle select for menopause [1...
FROM HIGH-FIDELITY NUMERICAL SIMULATIONS OF A LIQUID-FILM ATOMIZATION TO A REGIME CLASSIFICATION
High-fidelity numerical simulations of spray formation were conducted with the aim of improving fundamental understanding of airblast liquid-film atomization. The gas/liquid interaction in the near-nozzle region is investigated...
Chemoselective Installation of Amine Bonds on Proteins through Aza-Michael Ligation.

Feb 07, 2018
Chemical modification of proteins is essential for a variety of important diagnostic and therapeutic applications. Many strategies developed to date lack chemo- and regioselectivity as well as result in non-native linkages that...

Brexit and the Anglosphere
Brexit supporters often point to Anglophone countries as an obvious replacement for the UK’s relationship with the European Union. But where did this idea of an Anglosphere come from? And how significant is it? Michael Kenny and...

Untangling the oxidative cost of reproduction

Mar 08, 2022
The cost of reproduction plays a central role in evolutionary theory, but the identity of the underlying mechanisms remains a puzzle. Oxidative stress has been hypothesized to be a proximate mechanism that may explain the cost...
