COLLECTIVE EXCITATIONS IN ALPHA-HELICAL PROTEIN MOLECULE
Российский технологический журнал, 2018 Continuous energy supply, a necessary condition for life, excites a state far from thermodynamic equilibrium, in particular coherent electric polar vibrations depending on water ordering in the cell.

Guest editorial—the ballyhoo over polar bears
, 2009 Critics have said that there’s little or no justification for the focus that polar bears (Ursus maritimus) have received as a threatened species. Recent studies project dramatic reductions in polar bear numbers in just a few decades, in concert with the ...

Ichnodiversity in the eastern Canadian Arctic in the context of polar microbioerosion patterns
, 2022 Studies of marine microbioerosion in polar environments are scarce. They include our recent investigations of bioerosion traces preserved in sessile balanid skeletons from the Arctic Svalbard archipelago and the Antarctic Ross Sea.

Implantable Ionic Memristors Based on Natural Polymer Heterojunctions
Advanced Functional Materials, EarlyView.We report an implantable natural polymer‐based ionic memristor composed of hyaluronic acid, chitosan, and PDMS. The device achieved 98.94% accuracy in MNIST classification while reducing training time by 36.8% compared with a conventional artificial neural network (ANN).

Can we explain the post-2015 absence of the Chandler wobble?
Earth, Planets and SpaceRecent polar motion data do not show a 6-year beat and indicate the absence of the Chandler wobble (CW), whereas we could observe the 6-year beat even in the 1920-40 s when the CW amplitude was known to be smallest.

Analytical models and amplification effects of seismic wave propagation in canyon sites
Yantu gongcheng xuebao, 2019 Morphologically, there are three types of topographic and site conditions in nature: flat, convex and concave sites. The canyon (or valley) is a common concave site, and a large number of structures such as earth-rock dams and bridges have been built in ...

Water storage contributions to the excitation of polar motion
, 1989 textThe goal of this research was to investigate further the role of air redistribution and continental water storage changes in the excitation of both the annual and Chandler wobbles for the period 1900-85.
