Potential climatic transitions with profound impact on Europe [PDF]

open access: yes, 2011
We discuss potential transitions of six climatic subsystems with large-scale impact on Europe, sometimes denoted as tipping elements. These are the ice sheets on Greenland and West Antarctica, the Atlantic thermohaline circulation, Arctic sea ice, Alpine

Monstars on Glaciers [PDF]

open access: yesJournal of Glaciology, 1983
AbstractIsotropic points are structurally stable features of any complicated field of stress or strain-rate, and therefore will almost always be present on the surface of a glacier. A given isotropic point for strain-rate will belong to one of six different classes, depending on the pattern (lemon, star, or monstar) of principal directions and the ...

Covalent Organic Frameworks‐Delivered Reuterin Drives Trained Immunity in Tumor‐Associated Macrophages to Enhance Melanoma Immunotherapy via Glycerophospholipid Metabolism

open access: yesAdvanced Science, EarlyView.
Covalent organic framework (COF)‐reuterin induces trained immunity in tumor‐associated macrophages, promoting the generation of nitric oxide and reactive oxygen species, thereby enhancing the antitumor immune response. Additionally, COF‐Reuterin directly kills tumor cells while simultaneously eradicating pathogenic intratumoural bacteria.

Thinned and Welded Silver Nanowires for Intelligent Pressure and Humidity Sensing Enabled by Machine Learning

open access: yesAdvanced Science, EarlyView.
Thinned and welded silver nanowires are prepared by selectively engineering their morphology and structure. The resulting films show enhanced optical, electrical, thermal, and mechanical properties. By incorporating machine learning, the developed pressure and humidity sensors are able to accurately identify finger pressing behaviors, monitor human ...

Glaciers in Wales [PDF]

open access: yesThe Geologist
In the year 1851 I read a paper before the Geological Society “On the Superficial Accumulations and Surface-markings in North Wales,” in which I attempted to show that there had been two glacier epochs in that country, one before, and the other after the deposition of the boulder drift, which was ploughed out of some of the larger valleys by the ...

Spatiotemporal Transcriptomic Atlas Reveals the Regulatory Mechanisms Underlying Early Inflorescence Development and Sex Differentiation in Spinach

open access: yesAdvanced Science, EarlyView.
High‐resolution spatiotemporal transcriptomic data from male and female spinach inflorescences across four key stages first reveal the sex differentiation initiates at the four‐leaf stage and is governed by epigenetic regulation via the SpMSI1‐SpHDT2 complex.
