    Description: The dataset is a rock glacier inventory of the West Kunlun Mountains of China. It contains the boundaries of the landforms, their geometric information, and kinematic data. The inventory has been compiled followed the IPA guidelines on mapping rock glaciers. Remote sensing data adopted to produce this dataset includes optical images (Google Earth and Sentinel-2 images) and Interferometric SAR (InSAR) images (ALOS-1 PALSAR). Both manual inspection and deep learning-powered automatic detection have been used to identify and delineate the landforms. The geometric information of the inventoried landforms has been derived from SRTM DEM and Tandem-X DEM. The kinematic data has been quantified from ALOS-1 PALSAR data during 2006–2010. Specific temporal coverage for each displacement rate is included in the attribute table of the ESRI Shapefile. It is the first rock glacier inventory of the arid West Kunlun region, aiming to provide the baseline knowledge of these ice-rich landforms for long-term monitoring in the warming climate.

    Notes: Natural fibers are excellent substitute materials for man made fibers in making fiberreinforced composites due to their high specific strength and modulus, low density, low price, easyavailability in some countries, recyclable and degradable properties. They have raised great attentionsamong material scientists and engineers in the past decade. Many researches have been conducted tostudy the mechanical properties, especially interfacial properties of natural fiber reinforcedcomposites. However, the properties, such as mechanical performances, moisture absorptionbehaviors, et. al of natural fibers themselves have been seldom investigated. Knowing the relationshipbetween microstructures and properties of natural fibers are important for understanding the bulkproperties of natural fiber composites and also good instructions for designing bio-mimic materials.In this study, four kinds of natural fibers which were extracted from different plant sources wereinvestigated. The microstructures of these natural fibers were revealed with the aid of opticalmicroscopy. Microstructure models were thereof set up and mechanical properties for therepresentative volume element were assumed. Fiber bundle fracture models together with probabilitystatistics analysis were employed to calculate the mechanical properties of natural fibers. The resultswere compared with the experimental measurements. Different mechanical behaviors of naturalfibers which were functioned differently in the nature were clearly explained by the above studies

    Notes: Oxygen-limiting conditions are critical to the survival of the bacteria in tuberculosis. Mycobacterium tuberculosis can survive anaerobiosis in vitro for long periods of time only after a gradual transition to a microaerophilic stationary phase. The underlying mechanism behind stationary phase adaption needs to be elucidated. The protein profiles of Mycobacterium tuberculosis during long-term stationary phase growth and under strict anaerobic incubation were monitored by [35S]methionine labelling, SDS-PAGE and fluorography. These experiments have established that protein synthesis gradually decreased over 50 days in the long-term stationary phase cultures which were considered to be microaerophilic. There was an 80% linear decrease in the level of total protein synthesis during the first 40 days of microaerophilic growth and then the rate of protein synthesis faded quickly. For the first time we have shown that total protein synthesis shutdown occurred when bacilli were incubated under further anaerobic conditions. Viability, estimated by cfu counts, remained constant during stationary phase growth and under anaerobic incubation. Furthermore, when oxygen was introduced into the anaerobic culture, protein synthesis restarted. Also heat shock at 45°C, 48°C and 50°C rapidly induced protein synthesis in stationary and anaerobic cultures. These data indicate that dormant bacteria shut down protein synthesis but remain responsive to specific stimuli which restore protein synthesis. In addition the dormant bacilli induced by anaerobiosis developed more heat resistance than non-dormant organisms.

    Notes: A matrix of twelve laboratory heat treated iron-silicon specimens were investigated toidentify the microtextures, grain misorientations and grain size distributions present and to relate them to the various silicon contents and annealing cycles. The steel grades examined contained either 1.0%, 2.4% or 3.0% silicon. The results showed that the higher strain levels present in the hot rolled microstructures as silicon content increased created a greater driving force for recovery, recrystallisation and grain growth processes

    Notes: [Auszug] (A+U)-rich elements (AREs) within 3′ untranslated regions are signals for rapid degradation of messenger RNAs encoding many oncoproteins and cytokines. The ARE-binding protein AUF1 contributes to their degradation. We identified MYC proto-oncogene mRNA as a cellular AUF1 target. Levels of MYC ...

    Description: Incorporation of subducted slab in arc volcanism plays an important role in producing the geochemical and isotopic variations in arc lavas. The mechanism and process by which the slab materials are incorporated, however, are still uncertain. Here, we report, to our knowledge, the first set of Mg isotopic data for a suite of arc lava samples from Martinique Island in the Lesser Antilles arc, which displays one of the most extreme geochemical and isotopic ranges, although the origin of this variability is still highly debated. We find the δ26Mg of the Martinique Island lavas varies from −0.25 to −0.10, in contrast to the narrow range that characterizes the mantle (−0.25 ± 0.04, 2 SD). These high δ26Mg values suggest the incorporation of isotopically heavy Mg from the subducted slab. The large contrast in MgO content between peridotite, basalt, and sediment makes direct mixing between sediment and peridotite, or assimilation by arc crust sediment, unlikely to be the main mechanism to modify Mg isotopes. Instead, the heavy Mg isotopic signature of the Martinique arc lavas requires that the overall composition of the mantle wedge is buffered and modified by the preferential addition of heavy Mg isotopes from fluids released from the altered subducted slab during fluid−mantle interaction. This, in turn, suggests transfer of a large amount of fluid-mobile elements from the subducting slab to the mantle wedge and makes Mg isotopes an excellent tracer of deep fluid migration.

    Description: Flexible and low-cost poly(ethylene oxide) (PEO)-based electrolytes are promising for all-solid-state Li-metal batteries because of their compatibility with a metallic lithium anode. However, the low room-temperature Li-ion conductivity of PEO solid electrolytes and severe lithium-dendrite growth limit their application in high-energy Li-metal batteries. Here we prepared a PEO/perovskite Li3/8Sr7/16Ta3/4Zr1/4O3 composite electrolyte with a Li-ion conductivity of 5.4 × 10−5 and 3.5 × 10−4 S cm−1 at 25 and 45 °C, respectively; the strong interaction between the F− of TFSI− (bis-trifluoromethanesulfonimide) and the surface Ta5+ of the perovskite improves the Li-ion transport at the PEO/perovskite interface. A symmetric Li/composite electrolyte/Li cell shows an excellent cyclability at a high current density up to 0.6 mA cm−2. A solid electrolyte interphase layer formed in situ between the metallic lithium anode and the composite electrolyte suppresses lithium-dendrite formation and growth. All-solid-state Li|LiFePO4 and high-voltage Li|LiNi0.8Mn0.1Co0.1O2 batteries with the composite electrolyte have an impressive performance with high Coulombic efficiencies, small overpotentials, and good cycling stability.
