Manzhu Yu, Chaowei Yang
Dust storms are devastating natural disasters that cost billions of dollars and many human lives every year. Using the Non-Hydrostatic Mesoscale Dust Model (NMM-dust), this research studies how different spatiotemporal resolutions of two input parameters (soil moisture and greenness vegetation fraction) impact the sensitivity and accuracy of a dust model. Experiments are conducted by simulating dust concentration during July 1-7, 2014, for the target area covering part of Arizona and California (31, 37, -118, -112), with a resolution of ~ 3 km...

The market squid, Doryteuthis opalescens, is an important forage species for the inshore ecosystems of the California Current System. Due to increased upwelling and expansion of the oxygen minimum zone in the California Current Ecosystem, the inshore environment is expected to experience lower pH and [O2] conditions in the future, potentially impacting the development of seafloor-attached encapsulated embryos. To understand the consequences of this co-occurring environmental pH and [O2] stress for D. opalescens encapsulated embryos, we performed two laboratory experiments...

Hexavalent chromium (Cr(VI)) is generated in serpentine soils and exported to surface and groundwaters at levels above health-based drinking water standards. Although Cr(VI) concentrations are elevated in serpentine soil pore water, few studies have reported field evidence documenting Cr(VI) production rates and fluxes that govern Cr(VI) transport from soil to water sources. We report Cr speciation (i) in four serpentine soil depth profiles derived from the California Coast Range serpentinite belt and (ii) in local surface waters...

Erin F E Lennon, Benjamin Z Houlton
Denitrification removes ecologically available nitrogen (N) from the biosphere and influences both the pace and magnitude of global climate change. Disagreements exist over the degree to which this microbial process influences N-availability patterns across Earth's ecosystems. We combine natural stable isotope methods with qPCR to investigate how denitrifier gene abundance is related to variations in nitrate (NO3(-)) pool sizes across diverse terrestrial biomes and conditions. We analyze NO3(-) isotope composition ((15)N/(14)N, (18)O/(16)O) and denitrifier gene nirS in 52 soil samples from different California ecosystems, spanning desert, chaparral, oak-woodland/savanna and forest...

We present a gridded inventory of US anthropogenic methane emissions with 0.1° × 0.1° spatial resolution, monthly temporal resolution, and detailed scale-dependent error characterization. The inventory is designed to be consistent with the 2016 US Environmental Protection Agency (EPA) Inventory of US Greenhouse Gas Emissions and Sinks (GHGI) for 2012. The EPA inventory is available only as national totals for different source types. We use a wide range of databases at the state, county, local, and point source level to disaggregate the inventory and allocate the spatial and temporal distribution of emissions for individual source types...

BACKGROUND: Shoulder pain and loss of function are directly associated with obesity. QUESTIONS/PURPOSES: We hypothesized that significant interactions would exist between total shoulder arthroplasty (TSA) and reverse total shoulder arthroplasty (RSA) and obesity status on functional and quality of life (QOL) outcomes over the long term. Clinical and QOL outcomes (American Shoulder and Elbow Surgeons Evaluation form, Shoulder Pain and Disability Index, University of California at Los Angeles Shoulder Rating scale, Medical Outcomes Short Form 12 (SF-12), range of motion (ROM), and strength) were longitudinally compared in patients with low and high body mass index (BMI) after a TSA or a RSA...

BACKGROUND: Gonadectomy is one of the most common procedures performed on dogs in the United States. Neutering has been shown to reduce the risk for some diseases although recent reports suggest increased prevalence for structural disorders and some neoplasias. The relation between neuter status and autoimmune diseases has not been explored. This study evaluated the prevalence and risk of atopic dermatitis (ATOP), autoimmune hemolytic anemia (AIHA), canine myasthenia gravis (CMG), colitis (COL), hypoadrenocorticism (ADD), hypothyroidism (HYPO), immune-mediated polyarthritis (IMPA), immune-mediated thrombocytopenia (ITP), inflammatory bowel disease (IBD), lupus erythematosus (LUP), and pemphigus complex (PEMC), for intact females, intact males, neutered females, and neutered males...

OBJECTIVE: Schizophrenia and bipolar disorder are associated with cognitive impairment leading to social disruption. While previous studies have focused on the effect of individual infectious exposure, namely, Herpesviridae viruses or Toxoplasma gondii (T gondii), on cognitive functioning, the objective of the present study was to examine the effect of multiple infections on cognitive functioning in patients with schizophrenia and bipolar disorder and in healthy controls. METHODS: Seropositivity to herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2), cytomegalovirus (CMV), and T gondii was related to cognitive status among 423 participants (recruited between 2008 and 2014; 138 patients with bipolar disorder, 105 patients with schizophrenia [DSM-IV criteria], and 180 healthy controls) for episodic verbal memory (California Verbal Learning Test), working memory (Wechsler Adult Intelligence Scale, third edition), and premorbid intelligence quotient (National Adult Reading Test)...

Importance: Neurophysiologic measures of early auditory information processing (EAP) are used as endophenotypes in genomic studies and biomarkers in clinical intervention studies. Research in schizophrenia has established correlations among measures of EAP, cognition, clinical symptoms, and functional outcome. Clarifying these associations by determining the pathways through which deficits in EAP affect functioning would suggest when and where to therapeutically intervene. Objectives: To characterize the pathways from EAP to outcome and to estimate the extent to which enhancement of basic information processing might improve cognition and psychosocial functioning in schizophrenia...

Earth-observing remote sensing data, including aerial photography and satellite imagery, offer a snapshot of the world from which we can learn about the state of natural resources and the built environment. The components of energy systems that are visible from above can be automatically assessed with these remote sensing data when processed with machine learning methods. Here, we focus on the information gap in distributed solar photovoltaic (PV) arrays, of which there is limited public data on solar PV deployments at small geographic scales...
