Food insecurity and unemployment among immigrants in the United States

American Journal of Agricultural Economics, EarlyView.
Abstract Immigrants can be more vulnerable to economic downturns and, during periods of economic hardship, more likely to experience food insecurity compared to natives. This study examines the differential effect of the unemployment rate on the probability of being food insecure among diverse groups of immigrant households relative to natives in the ...

Evidence of soft bound behaviour in analogue memristive devices for neuromorphic computing

Scientific Reports, 2018
The development of devices that can modulate their conductance under the application of electrical stimuli constitutes a fundamental step towards the realization of synaptic connectivity in neural networks. Optimization of synaptic functionality requires

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

IrMn-Cluster-Based Artificial Metalloenzymes with Radiosensitized Systemic Antitumor Responses to Prevent Malignant Tumor Metastasis and Recurrence

Nano-Micro Letters
Highlights The bioinspired design of IrMn-based redox centers (IMM) with rapid electron transfer can promote the formation of electron-rich IMM, thereby guaranteeing superior radio-enhanced reactive oxygen species biocatalysis and O2 generation.

The Interactive Multiple Model Strategy With Matrix Form Mode Probability for Models With Different State Vectors

IEEE Access
The Interactive Multiple Model (IMM) strategy is widely used for systems with multiple operating modes characterized by varying dynamics. This approach is particularly effective when a system undergoes sudden transitions between different modes, such as ...

A Cost-Effective Vehicle Localization Solution Using an Interacting Multiple Model−Unscented Kalman Filters (IMM-UKF) Algorithm and Grey Neural Network

Sensors, 2017
In this paper, we propose a cost-effective localization solution for land vehicles, which can simultaneously adapt to the uncertain noise of inertial sensors and bridge Global Positioning System (GPS) outages. First, three Unscented Kalman filters (UKFs)

Melatonin Levels in 89 Individuals With Smith Magenis Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT In patients with Smith–Magenis syndrome (SMS), an inverted circadian rhythm of melatonin (MT) contributes to the sleep disturbance. Standard treatment of sleep disturbance with MT often leads to extremely high daytime MT levels, resulting in even more sleep disorders. We therefore retrospectively evaluated the MT data of 89 SMS patients.

A proteomic study of memory after imprinting in the domestic chick

Frontiers in Behavioral Neuroscience, 2015
The intermediate and medial mesopallium (IMM) of the domestic chick forebrain has previously been shown to be a memory system for visual imprinting. Learning-related changes occur in certain plasma membrane and mitochondrial proteins in the IMM.

Hyperacute Interleukin‐1β Production and Neutrophil Extracellular Trap Formation in the Cerebral Circulation of Stroke Patients with Large Vessel Occlusion

Annals of Neurology, EarlyView.
Acute ischemic stroke due to large vessel occlusion is associated with rapid intravascular immune activation. Analysis of arterial blood sampled distal to the thrombus during mechanical thrombectomy revealed increased extracellular adenosine triphosphate (ATP) and interleukin‐1β (IL‐1β) levels, evidence of inflammasome priming in monocytes, and ...
