Palaeolithic extinctions and the Taurid Complex

, 2010
Intersection with the debris of a large (50-100 km) short-period comet during the Upper Palaeolithic provides a satisfactory explanation for the catastrophe of celestial origin which has been postulated to have occurred around 12900 BP, and which ...

Local manifestations of cometary activity [PDF]

, 2019
Comets are made of volatile and refractory material and naturally experience various degrees of sublimation as they orbit around the Sun. This gas release, accompanied by dust, represents what is traditionally described as activity.

Ion‐Gating Reservoir Computing for Preprocessing‐Free Speech Recognition from Throat Vibrations

Advanced Electronic Materials, EarlyView.
This work presents a throat‐mounted mechanoelectric sensor integrated with an ion‐gel/graphene reservoir device for on‐device speech recognition. The system converts raw biomechanical vibrations into rich nonlinear current dynamics, enabling efficient classification through a simple linear readout. The approach highlights a compact and tunable physical‐

Genese des Nordseeraumes im Quartär

Fennia: International Journal of Geography, 1974
In spite of alterations due to transgressions, Pleistocene forms are still discernible in the North Sea area. In this study, explanation of their genesis is based on a reconstruction of the ice‑sheds of different dimen­sions and the dynamic elements of ...

Groundwater dynamics beneath a marine ice sheet [PDF]

The Cryosphere
Sedimentary basins beneath many Antarctic ice streams host substantial volumes of groundwater, which can be exchanged with a “shallow” subglacial hydrological system of till and channelised water.

A Leaf‐Inspired Janus‐Structured Triboelectric‐Moisture Hybrid Energy Harvester

Advanced Energy Materials, EarlyView.
This study proposes a bioinspired Janus structured energy‐leaf with hybrid triboelectric‐moisture hybrid energy harvesters. This hybrid energy harvester is demonstrated in an intelligent emergency system for effective distress signaling and evacuation guiding during potential crises.

Multi-decadal evolution of Crary Ice Rise region, West Antarctica, amid modern ice-stream deceleration

Journal of Glaciology
The ongoing deceleration of Whillans Ice Stream, West Antarctica, provides an opportunity to investigate the co-evolution of ice-shelf pinning points and ice-stream flux variability.

Evolution of a stream ecosystem in recently deglaciated terrain

, 2011
Climate change and associated glacial recession create new stream habitat that leads to the assembly of new riverine communities through primary succession.

Selective Electrolysis of Water Under Artificial Seawater Conditions Using Transition Metal Borate Anodes

Advanced Energy Materials, EarlyView.
The borate‐based cobalt‐iron catalyst promotes selective oxidation of water rather than chlorine evolution reaction during electrolysis of seawater. When integrated into a zero‐gap electrolyzer prototype, this catalyst supports robust splitting of artificial seawater into oxygen and hydrogen on an extended timescale.

Beyond PEGylation: Archaeal Lipids for Long‐Circulating Liposomes

Advanced NanoBiomed Research, EarlyView.
Archaeal lipid‐based liposomes, particularly those containing caldarchaeol (GDGT), were found to significantly prolong the circulation time of vancomycin in rats, matching the pharmacokinetic properties of PEGylated systems. These findings suggest archaeal lipids as promising non‐PEG excipients for parenteral applications to minimize drug clearance ...
