A generalized approach for enhancing contact-electro-catalysis of oxides in a broad temperature range by fluorination

open access: yesNature Communications
Contact-electro-catalysis (CEC) has emerged as a sustainable and effective strategy for promoting chemical reactions. While polymers are the mostly used CEC catalysts, their limited contact-electrification (CE) performance at high temperatures limits the

Contact-electro-catalysis at Dynamic Semiconductor–Water Junctions

open access: yesResearch
Junctions are the fundamental elements of semiconductor devices, which are crucial for advancements in modern technology. However, most junctions involve static solid interfaces. Here, we studied a dynamic Schottky-like junction formed at a semiconductor–

Golgi enzymes are retrieved from the plasma membrane to the trans‐Golgi network

open access: yesFEBS Letters, EarlyView.
Golgi enzymes are traditionally considered resident proteins retained within the Golgi apparatus. Here, we demonstrate that a subset transiently reaches the cell surface and is subsequently retrieved to the trans‐Golgi network via retrograde transport. Using a nanobody‐based toolkit, we uncover a dynamic trafficking cycle of several Golgi enzymes.

Quantifying Information without Entropy: Identifying Intermittent Disturbances in Dynamical Systems

open access: yes, 2020
A system’s response to disturbances in an internal or external driving signal can be characterized as performing an implicit computation, where the dynamics of the system are a manifestation of its new state holding some memory about those disturbances.

Some Upper Bounds for Relative Entropy and Applications [PDF]

open access: yes, 1998
In this paper we derive some upper bounds for the relative entropy D(p || q) of two probability distribution and apply them to mutual information and entropy mapping.

Mean Entropies

open access: yesOpen Systems & Information Dynamics, 2005
Entropies are expressed in terms of mean values, and not as weighted arithmetic means of their generating functions, which result in pseudo-additive entropies. The Shannon entropy corresponds to the logarithm of the inverse of the geometric mean, while the Rényi entropy, more generally, to the logarithm of the inverse of power means of order τ < 1 ...

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Free entropy

open access: yesBulletin of the London Mathematical Society, 2000
Free entropy is the analogue of entropy in free probability theory. The paper is a survey of free entropy, its applications to von Neumann algebras and its connections to random matrix theory, as well as a discussion of open problems and of a basic variational problem, connected to random multimatrix models.

Translophagy—A potential link between autophagy impairment and translational errors

open access: yesFEBS 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.

Electron Redistribution Drives Structural Ordering in Sulfate (SO4) Adlayers

open access: yesChemElectroChem
In this work, the coadsorption of SO4 and H2O at the Au(111)‐electrolyte interface is investigated. It is uncovered how electron redistribution between coadsorbates correlates with the formation of tightly packed (√3a) SO4‐adsorbate chains, which have ...
