Translophagy—A potential link between autophagy impairment and translational errors
FEBS Letters, EarlyView.Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Analog Computing - past, present, future?
, 2020 As classic stored-program digital computers are reaching physical and practical limits with respect to clock frequency, integration density, and suffer from problems like Amdahl's law, unconventional approaches to high-speed and/or high-energy-efficient ...

Transmissive nonlocal multilayer thin film optical filter for image differentiation
Nanophotonics, 2021 It is well-known that a Fourier optical system can be used to perform specific computing tasks, such as image differentiation, with a superior speed and power consumption in comparison with digital computers, despite bulky optical components that are ...

An asynchronous spike event coding scheme for programmable analog arrays [PDF]
, 2008 This paper presents a spike event coding scheme for the communication of analog signals in programmable analog arrays. In the scheme presented here no events are transmitted when the signals are constant leading to low power dissipation and traffic ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Advances in Applied Mathematics, 1993 People have been aware of the limitations of the ``general purpose analog computer'' (better called the ``differential analyzer'') for some time. Just as examples, it cannot compute the Euler gamma function, or the Riemann zeta function, or solve the Dirichlet problem for Laplace's equation in the disk, although it can compute most of the other special

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.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 ...

, 2023 In the 1800s, Charles Babbage envisioned computers as analog devices. However, it was not until 150 years later that a Mechanical Analog Computer was constructed for the US Navy to solve differential equations.
