Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Optimization of High‑Speed WIG Airfoil with Consideration of Non‑ground Effect by a Two‑Step Deep Learning Inverse Design Method

Transactions of Nanjing University of Aeronautics and Astronautics
Under complex flight conditions， such as obstacle avoidance and extreme sea state， wing-in-ground （WIG） effect aircraft need to ascend to higher altitudes， resulting in the disappearance of the ground effect.

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Effect of radii of exemption on ground delay programs with operating cost based cruise speed reduction [PDF]

, 2013
When a ground delay program (GDP) is defined, a radius of exemption is typically set to exclude from having to realize ground delay aircraft departing from greater distances than the selected radius distance. A trade-off exists when defining this radius:

A Residual PPO Method for Shipboard Helicopter Landing Control

Aerospace
Shipboard helicopter landing in the near-deck region requires stable attitude regulation and high-precision deck-relative motion control under substantial model uncertainty and environmental disturbances, conditions under which conventional model-based ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Ground instability effects

This chapter is conceived to describe methodologies for the generation of scenarios having as effects ground deformation processes (landslides, subsidence and underground cavity collapses) triggered by different inputs. Special attention has been devoted to products for the aware management of the territory and to define strategies for the community ...
