Membrane Wrapping for High Capacity and Rapidly Switchable Adhesives
Advanced Functional Materials, EarlyView.A membrane‐wrapping mechanism enables high‐capacity, rapidly switchable adhesion by coupling suction, friction, and adhesion. Broadband performance is achieved in dry and underwater conditions, allowing fast, reversible manipulation of objects of diverse sizes and shapes, from delicate eggs and berries to flat, complex, or heavy objects. These outcomes

According to scientists we all are experiencing "Extreme Events" every day. Even by being part of a traffic jam. In order to better understand these extreme events, the data of over one hundred gauging stations along the "Kölner Ring" (a Freeway around the city of Cologne) is being collected and analyzed. To help the scientists to understand their data,

We discuss concepts for the prediction of extreme events based on time series data. We consider both probabilistic forecasts and predictions by precursors. Probabilistic forecasts employ estimates of the probability for the event to follow, whereas precursors are temporal patterns in the data typically preceeding events. Theoretical considerations lead

The assessment of risks posed by natural hazards such as floods, droughts, earthquakes, tsunamis or cyclones is often based on short-term historical records that may not reflect the full range or magnitude of events possible. As human populations grow, especially in hazard-prone areas, methods for accurately assessing natural hazard risks are becoming ...

Even though extremes seem to occur more often in recent times, they are by definition rare events. This poses challenges on the modeling and prediction of these processes, as we have only few samples. This class is meant as a gentle introduction into extreme value theory in the uniand multivariate case.

The monograph covers the fundamentals and the consequences of extreme geophysical phenomena like asteroid impacts, climatic change, earthquakes, tsunamis, hurricanes, landslides, volcanic eruptions, flooding, and space weather. This monograph also addresses their associated, local and worldwide socio-economic impacts. The understanding and modelling of

AbstractCompound extreme weather events are frequent and exhibit new features in the context of global change. This study unravels the characteristics, variations, and driving factors of compound extreme temperature‐extreme dust events in the Gobi Desert (GD) during the springs of 2000–2023. The temperature in the GD is high before extreme dust events (

Extreme scattering events (ESEs) are caused by the occultation to radio sources by AU-sized objects (or lenses). Free electrons in the lens seem to be responsible for the dramatic flux changes during the occultation but the nature of the lens is still a mystery. The lens may be a peculiar lump of interstellar medium (ISM). Recent self-gravitating cloud
