Abstract. To identify major sources of ambient fine particulate matter (PM2.5, dp < 2.5 μm) and quantify their contributions in the state California, a positive matrix factorization (PMF) receptor model was applied on Speciation Trends Network (STN) data, collected between 2002 2007 at eight distinct sampling locations, including El Cajon, Rubidoux, Los Angeles, Simi Valley, Bakersfield, Fresno, San Jose, Sacramento. Between five to nine PM were identified each site, several which common...
With the widespread vaccinations against coronavirus disease 2019 (COVID-19), we are witnessing gradually waning neutralizing antibodies and increasing cases of breakthrough infections, necessitating development drugs aside from vaccines, particularly ones that can be administered outside hospitals. Here, present two cross-reactive nanobodies (R14 S43) their multivalent derivatives, including decameric (fused to immunoglobulin M [IgM] Fc) maintain potent activity severe acute respiratory...
Abstract In situ monitoring of hydrogen peroxide (H 2 O ) during its production process is needed. Here, an electrochemical H sensor with a wide linear current response range (concentration: 5 × 10 −8 to −2 m ), low detection limit (32.4 −9 and high sensitivity (568.47 µA −1 cm developed. The electrocatalyst the consists cobalt nanoparticles atomic Co‐N x moieties anchored on nitrogen doped carbon nanotube arrays (Co‐N/CNT), which obtained through pyrolysis sandwich‐like urea@ZIF‐67 complex....
Water-soluble inorganic (WSI) ions are major components of ambient air PM2.5 (particulate matter diameter ≤2.5 μm); however, their potential health effects understudied. On C57BL/6 mice, we quantified the effect three WSIs (NO3–, SO42–, and NH4+) on respiratory systems. Exposure scenarios include different WSI types, concentrations, animal development stages (young vs adult), sex. The exposure were comprehensively assessed, with special focus function tissue/cell level changes. Chronic NO3–...
An approach to storing of temporal sequences that deals with complex directly is presented. Short-term memory (STM) modeled by units comprised recurrent excitatory connections between two neurons. A dual-neuron model proposed. By applying the Hebbian learning rule at each synapse and a normalization among all synaptic weights neuron, it shown quantity called input potential increases monotonically sequence presentation, neuron can only be fired when its signals are arranged in specific...
In this study, potential sources of water-soluble (WS) and water-insoluble (WI) fractions metals trace elements in coarse particulate matter (CPM) (PM(10-2.5), 2.5 < dp 10 μm) were identified their association with the redox properties CPM, measured by means reactive oxygen species (ROS), was explored. CPM collected during 2012-2013 Central Los Angeles (LA) 2013-2014 Anaheim, CA. Generally, WI components contributed to a larger fraction ROS activity (as much as 64% 54% at LA respectively)....
This study examines the associations between oxidative potential of ambient PM<sub>2.5</sub>and PM<sub>0.18</sub>, measured by means dithiothreitol (DTT) assay, and their chemical constituents modeled sources. Particulate matter (PM) samples were collected from 2012–2013 in Central Los Angeles (LA) 2013–2014 Anaheim, California, USA. Detailed analyses PM samples, including carbonaceous species, inorganic elements water-soluble ions, conducted. Univariate analysis indicated a high correlation...
