Fluids in subduction zones can have major effects on subduction dynamics. However, geophysical constraints on the scale and impact of fluid flow during continental subduction are still limited. Here we analyze the VP/VSratios in the Western Alpine region, hosting one of the best-preserved fossil continental subduction zones worldwide, to investigate the impact of fluid flow during continental subduction. We found a belt of high VP/VSratios >1.9 on the upper-plate side of the subduction zone,consistent with a partially serpentinized upper-plate mantle, and a belt of unusually low VP/VSratios <1.7 on the lower-plate side,at depths shallower than 30 km. We propose that these low VP/VSratios result from a widespread network of silica-rich veins,indicating past fluid flow along the continental subduction interface. Our results suggest that past fluid flow may have reduced the effective stress along the subduction interface thus favoring continental subduction.

The karyotype of Caspian goby was studied, which has been identified as Caspian bighead goby - Neogobius gorlap before. The results of cytogenetic analyses have shown that the diploid set of goby varies from 38 to 40 chromosomes, which is different from bighead goby (2n = 43-46). We assumed that Caspian goby has independence as a species.

Rhythmic oscillatory patterns sustain cellular dynamics, driving the concerted action of regulatory molecules, microtubules, and molecular motors. We describe cellular microtubules as oscillators capable of synchronization and swarming, generating mechanical and electric patterns that impact biomolecular recognition. We consider the biological relevance of seeing the inside of cells populated by a network of molecules that behave as bioelectronic circuits and chromophores. We discuss the novel perspectives disclosed by mechanobiology, bioelectromagnetism, and photobiomodulation, both in term of fundamental basic science and in light of the biomedical implication of using physical energies to govern (stem) cell fate. We focus on the feasibility of exploiting atomic force microscopy and hyperspectral imaging to detect signatures of nanomotions and electromagnetic radiation (light), respectively, generated by the stem cells across the specification of their multilineage repertoire. The chance is reported of using these signatures and the diffusive features of physical waves to direct specifically the differentiation program of stem cells in situ, where they already are resident in all the tissues of the human body. We discuss how this strategy may pave the way to a regenerative and precision medicine without the needs for (stem) cell or tissue transplantation. We describe a novel paradigm based upon boosting our inherent ability for self-healing.

均相催化和多相催化通常被认为是独立甚至相互对立的学科.本文提出了一种新型的用于分子氧选择性氧化烷基苯的杂多酸/均相混合催化体系.该催化体系由N-羟基邻苯二甲酰亚胺(NHPI,用于自由基链式反应的均相有机催化剂)和纳米TiO_(2)(多相紫外光活性光氧化催化剂)两种组分组成.NHPI与TiO_(2)的协同作用使光氧化活性从紫外光转移到可见光,并产生邻苯二甲酰亚胺-N-氧基(PINO)自由基.NHPI/PINO催化的自由基链式反应能够在没有额外光输入的情况下进行,从而从根本上提高能源效率.通过控制NHPI/TiO_(2)比率优化产物选择性,进而使烷基芳烃优先形成过氧化氢或酮.

In the present work, disturbances of the half-transparency frequency fbEs of the ionospheric sporadic E-layer are investigated in connection with earthquakes. The fbEs-frequency is proportional to the square root of the maximum ionisation density of the sporadic E-layer. In this work, it is shown that in 2/3 of the cases, two days before a seismic shock with magnitude M > 5.5 and on the day of the shock, an increase of the fbEs-frequency is obtained at sunset hours at distances from the epicenter R km. In contrast, before sunrise, the fbEs-value decreases. The data analysed are obtained by the three vertical ionospheric sounding stations“Kokubunji”, “Yamagawa”, and “Wakkanai” during some tens of years.
