Beyond the GTP‐cap: Elucidating the molecular mechanisms of microtubule catastrophe
BioEssays, Volume 45, Issue 1, January 2023., 2023 Microtubule dynamics are essential for myriad cellular processes. The switching between microtubule growth and shrinkage is traditionally explained by the loss of a protective “cap” of GTP‐bound tubulin subunits from the growing microtubule end. New research shows that features beyond the nucleotide content at the growing end impact microtubule ...

Weak Keys in the Rekeying Paradigm: Application to COMET and mixFeed
IACR Transactions on Symmetric Cryptology, 2020 In this paper, we study a group of AEAD schemes that use rekeying as a technique to increase efficiency by reducing the state size of the algorithm. We provide a unified model to study the behavior of the keys used in these schemes, called Rekey-and ...

Optical Imaging Instruments and Main Science Results of Small Body Exploration: A Review
IEEE Access, 2021 Compared with planets and their moons, small bodies retain the characteristics of their early formation. Therefore small bodies, especially Near Earth Asteroids (NEA), have become one of the most valuable targets in space exploration. This paper presents

A translation of L. Euler's "On the motion of comets in parabolic orbits, having the Sun in the focus" [PDF]
, 2021 This is a translation from Latin of E840 'De motu cometarum in orbitis parabolicis, solem in foco habentibus', in which Euler addresses six problems related to comets in heliocentric parabolic orbits. Problem 1: Find the true anomaly of a heliocentric comet from the latus rectum of the orbit and the medium Earth to Sun distance.

InSAR‐Derived Horizontal Velocities in a Global Reference Frame
Geophysical Research Letters, 2023 Interferometric Synthetic Aperture Radar is used to measure deformation rates over continents to constrain tectonic processes. The resulting velocity measurements are only relative, however, due to unknown integer ambiguities introduced during ...

Constant strain accumulation rate between major earthquakes on the North Anatolian Fault
Nature Communications, 2018 Accumulation of interseismic strain may now be constrained by satellite observations. Here, the authors show that strain accumulation rates on the North Anatolian Fault are constant for the interseismic period indicating that lower-crustal viscosities ...
