Summary: The experiment conducted on a large animal model showed that single abrupt deflation from high positive end-expiratory pressure (PEEP) or repeated short deflations from moderate PEEP can cause pulmonary edema, impaired oxygenation, and increased pulmonary vascular resistance (PVR), consistent with previous findings in rodents. Rapid deflation may therefore be a clinically relevant cause of impaired lung function, which can be attenuated by gradual pressure release.

Summary: In this study, seismic reflection and P-wave tomography datasets were integrated with computed tomography-derived sedimentological analyses to estimate the volume of the iconic Minoan eruption. The results revealed a total eruption volume of 34.5 +/- 6.8 km(3), with different proportions of tephra fall deposits, ignimbrites, intra-caldera deposits, and lithics. These volume estimates were consistent with an independent caldera collapse reconstruction. The findings demonstrate the importance of complementary geophysical and sedimentological datasets for reliable eruption volume estimates and volcanic hazard assessments.

Summary: Ignimbrites represent a wide range of deposit types associated with volcanic eruptions, lacking a quantified classification scheme and hindering the standardization of descriptors for ignimbrites. By studying correlations between runout, areal extent, aspect ratio, and volume, it is possible to propose a classification scheme for ignimbrites based on field observables. The relationships identified suggest a power-law relationship between dispersal area/equivalent runout and bulk volume, providing insights into the dynamics of pyroclastic flows.

Summary: The study focused on the carbonate rhizoliths in dunes of the Badain Jaran Desert, NW China, revealing their connection with plant distribution and landscapes. Petrological and mineralogical analyses showed that the rhizolith cement is calcium carbonate, and soil moisture is crucial for sustaining plant growth and rhizolith formation. Desert rhizoliths can serve as a proxy for inferring local soil moisture and plant communities, also indirectly indicating aboveground environmental conditions related to climate and landscape position.

Summary: This study presents a novel method for fabricating wafer-scale silicon fractals, which form pyramids only in the lateral direction using the crystal orientation of silicon. By masking only the corners of a cavity in silicon with silicon nitride, fractals are created in silicon where the shape is determined by the crystal {111} planes of the silicon. The use of a planar silicon dioxide hard-mask on a silicon (100) wafer allows for the cutting of the octahedral cavity shaped by the {111} planes in half, resulting in pyramids with sharper edges and vertices at the base.

Summary: Deception Island in Antarctica is one of the most active volcanoes, with recent eruptions and episodes of volcanic unrest indicating a likelihood of future volcanic activity. Research on Stanley Patch volcano within the island's caldera depression has revealed its growth in a subaerial environment, shedding light on the island's geological evolution. The complete flooding of Port Foster likely occurred after the formation of Stanley Patch volcano, within the last approximately 2000 years.

Summary: The study investigates the origin, evolution, hydrocarbon accumulation mechanisms, and significance for future oil and gas exploration of the Pishan Caldera in the Tarim Basin of northwest China. The research reveals that volcanic eruptions, caldera collapse, and reactivation of the caldera led to Cretaceous oil migration and accumulation in Cretaceous breccia reservoirs. The study also proposes a generalized model for hydrocarbon reservoirs related to calderas.

Summary: This study reports an unprecedented method for electrochemically growing ordered metallic nanowire arrays using a solidified electrolyte solution below freezing temperature. The thickness of the electrodeposit can be instantaneously tuned and parallel ridges can be formed on a webbed film without the need for any template. After etching away the webbed film, an array of metallic nanowires with desired separation and width determined by applied pulses is formed on a substrate with arbitrary surface patterns. This work bridges the gap between top-down lithography and bottom-up self-organization in fabricating large-area, low-cost ordered metallic nanowire arrays.

Summary: The study uses a numerical model to investigate the controls on basaltic eruption style, focusing on Kilauea and Etna as case studies. Results suggest that lava fountaining is a distinct style, separate from effusive and explosive eruption styles. High lava fountains occur when the bubbly magma's Reynolds number is greater than approximately 0.1 and the bulk viscosity is less than 10(6) Pas.

Summary: Trace elements and volatile heterogeneity in the Earth's mantle are affected by the recycling of oceanic lithosphere through subduction processes. Boron isotopes are utilized as a tracer for recycled subducted materials, showing the fate of these materials in the mantle and the composition heterogeneity in various tectonic settings. The new data suggest the presence of depleted and enriched mantle components intrinsic to the Icelandic mantle source, highlighting the role of recycled subducted lithosphere in melt generation at ocean islands.

Summary: This study investigates matrix effects that arise during sulfur isotope analysis of glasses by SIMS, using over 600 sulfur isotope analyses of nine different glasses. The research reveals a nonlinear correlation between glass sulfur content and IMF, and demonstrates that models incorporating multiple elements can accurately predict instrumental mass fractionation. This highlights the importance of using well-characterized standards with a wide compositional range to calibrate SIMS instruments for sulfur isotope analyses of unknown silicate glasses.

Summary: The study investigated the impact of crystallisation kinetics on lava flow behavior by using real-time synchrotron X-ray microtomography to observe the nucleation and growth of clinopyroxene and plagioclase in oxidised, nominally anhydrous basaltic magma. It was found that under continuous cooling, the onset of key transitions in lava hardening occurred within a shorter timeframe, demonstrating the potential of real-time synchrotron X-ray tomography in analyzing the solidification history of basaltic lavas.

Summary: Recent studies have shown that ocean island basalts (OIBs) contain high levels of carbon, sulfur, and halogens. In El Hierro, Western Canary Islands, magmas with exceptionally high CO2 and sulfur contents have been erupting for centuries. By estimating the oxygen fugacity (fO(2)) and magmatic temperature for El Hierro, along with global mantle potential temperature data, researchers were able to assess the redox and temperature conditions during the early stages of volatile-rich OIB melt evolution. The results indicate highly oxidized magmas and provide insights into the mantle source beneath the Canary Islands.
