A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Volatile ZrO2 Antiferroelectric Tunnel Junctions for Rapid, Energy‐Efficient Physical Reservoir Computing

open access: yesAdvanced Science, EarlyView.
An antiferroelectric tunnel junction serves as a reservoir computing node, where field‐induced phase transitions and spontaneous ZrO2 relaxation deliver nonlinear fading memory. An In‐Ga‐Zn oxide interlayer enlarges the memory margin and multibit state richness.

Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

open access: yesAdvanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

A Covalent Organic Framework With Staggered Topology for Mimetic Transmembrane Transport of Hydrated Ions

open access: yesAdvanced Science, EarlyView.
Inspired by biological ion channels, an AB‐staggered β‐ketoenamine‐linked COF enables rapid hydrated‐ion transport through a biomimetic dehydration‐compensation mechanism, where carbonyl‐rich convergent channels partially offset ion dehydration energy. As aqueous Zn battery separators, the COF membranes suppress parasitic reactions and dendrite growth,

The burned-out missionary

Pediatrics, 1978
In a recent commentary in response to Anders' article,2 Rothenberg pointed out that individuals who have chosen pediatrics for any of these reasons [comfort with children rather than adults, need to be in control of patients, or reacting against basic dislike and discomfort with children] are obviously not going to be interested in ...

“Burning Out” versus “Punching Out”

Journal of Human Stress, 1980
Abstract “Burning Out” among air traffic controllers is the syndrome of depression, anxiety, fear of a midair collision, insomnia, and inability to function professionally with confidence. Individuals who suffer such reactions are rapidly retired for medical reasons from air traffic control work.

Global burn-out

2013
Il fallait établir ce constat : avant d'être un problème individuel, le burn-out est d'abord une pathologie de civilisation. Marquée par l'accélération du temps, la soif de rentabilité, les tensions entre le dispositif technique et des humains déboussolés, la postmodernité est devenue un piège pour certaines personnes trop dévouées à un système dont ...
