Cotton strips as a model substrate for analysis of leaf‐litter‐colonizing microbial assemblages in streams

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Leaf‐litter decomposition is a key indicator of the functional integrity of stream ecosystems and cotton strips have been employed as a standard substrate for quantification of litter‐decomposition rates in streams across the globe. Cotton strips also offer a standardized method for assessing structural integrity of stream microbial ...

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Tactical and Strategic Risks From Supply Disruptions in Competing Supply Chains

open access: yesNaval Research Logistics (NRL), EarlyView.
ABSTRACT Supply chain disruptions can lead to both tactical (i.e., loss of short‐term sales during a disruption) and strategic (i.e., loss of long‐term market share) consequences. We model the impact of a supply disruption on competing supply chains in which two firms compete for a limited backup supply.

Urinary Soluble Collagen Levels Are Associated With Moderate/Severe LUTS

open access: yesThe Prostate, EarlyView.
ABSTRACT Background Expansion of the stromal compartment of the prostate concurrent with fibroblast activation and increased collagenization is now recognized as a pathobiology likely contributing to Lower Urinary Tract Symptoms (LUTS). However, approaches to quantitatively and, ideally, non‐invasively, assess prostatic collagenization in vivo are not ...

2‐Amino‐3H‐phenoxazin‐3‐one is a lead inhibitor of Cuscuta campestris early development: structure–activity relationships of o‐aminophenol‐derived allelochemicals

open access: yesPest Management Science, EarlyView.
Phenoxazinones caused differential types of phytotoxic effects in C. campestris early development. APO is a coherent lead inhibiting C. campestris germination and early seedling growth. Abstract BACKGROUND 2‐Amino‐3H‐phenoxazin‐3‐one (synonym: questiomycin A; abbreviated as APO or Phx‐3) is a naturally occurring phenoxazinone‐type allelochemical with ...

Notoginsenoside R2 Antagonizes Renal Interstitial Fibrosis by Regulating Fatty Acid Oxidation via the CASP2/ALDH3A1 Axis

open access: yesPhytotherapy Research, EarlyView.
Proposed mechanism by which notoginsenoside R2 (NGR2) attenuates renal interstitial fibrosis. In injured renal tubular epithelial cells, CASP2 downregulation and enhanced ubiquitin‐dependent degradation of ALDH3A1 disrupt mitochondria‐associated endoplasmic reticulum membranes (MAMs) and impair fatty acid oxidation (FAO), leading to lipid accumulation ...

Evolution of sea fog based on meteorological and oceanographic observations during FATIMA Yellow Sea campaign

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This study presents a conceptual framework linking sea‐water temperature Tw gradients to the formation and persistence of sea fog in the southeastern Yellow Sea. Over cold waters maintained by tidal mixing, downward latent heat flux enhances lower‐level stability and sustains persistent sea fog, whereas over warmer waters, upward fluxes and thermal ...

Lightning electromagnetic emission location using arrival time differencing (LEELA): An introduction to the Met Office's next generation Very Low Frequency lightning location system

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Paleo-Ice Streams and Ice Stream Boundaries, Ross Sea, Antarctica

1997
During the RVIB Nathaniel B. Palmer 1994–01 and 1995–01 cruises, approximately 7141 km of 50 in3 airgun seismic profiles and 12,150 km of 3.5 kHz trackline data were collected from the Ross Sea continental shelf. Ross Sea is a broad embayment, approximately 1500 km wide and 900 km long, on the Antarctic coast (Fig. 1). Water depths range from less than

Streaming flexoelectricity in saline ice

Nature Materials
Despite 10% of the Earth's surface being covered by ice, ice power remains untapped. Although ice is known to generate electricity upon bending via flexoelectricity1, the generated electric polarization per curvature, that is, the flexoelectric coefficient, is too small (~1-10 nC m-1) to be utilized for electromechanical devices.
