How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Is the Value Added Tax Naturally Progressive? [PDF]
A broad based consumption tax, such as a value added tax, is generally considered to be a regressive tax. This conclusion, however, has not taken into account the fact that in developing countries the commodities on which poor households spend most of ...

Accurately predicting the added resistance coefficient in short waves remains a challenge. This study aims to investigate the added resistance of a container ship in regular short-head waves at moderate Froude numbers through unsteady RANS simulations. A

Effect of Graphene on Micro-Structure and Properties of MAO Coating Prepared on Mg-Li Alloy
Ceramic coating modified with graphene was formed on Mg-Li alloy by a micro-arc oxidation process in a graphene powders (GE) added silicate electrolyte. The microstructure, composition, tribological and corrosion behaviors of the coatings were performed.

Effect of STEP for Reducing Added Resistance in Waves
The present paper provides the results of an investigation on STEP (Spray Tearing Plate) for reducing the added resistance in waves.The research has been started to develop a device for suppressing spray; thin wave like a film that is generated around the bow above the waterline when a ship runs in waves.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Data-driven modeling and regression analysis on ship resistance of in-service performance
This study employs operational data to model ship resistance, aiming to bridge the gap between controlled experiments and real-world conditions. It comprehensively analyzes wind, waves, and currents, employing nonlinear regression and z-score filtering ...
