Magneto-Electric Dipole Antenna Arrays [PDF]
, 2014 A planar magneto-electric (ME) dipole antenna array is proposed and demonstrated by both full-wave analysis and experiments. The proposed structure leverages the infinite wavelength propagation characteristic of composite right/left-handed (CRLH ...

Goel′s Teflon sponge internal shunt for anterior spinal arachnoid cyst
Journal of Craniovertebral Junction and Spine, 2014 We report a case of a 6-year-old boy who presented with progressive quadriparesis and bowel-bladder incontinence. Magnetic resonance imaging (MRI) of the spine showed anteriorly located arachnoid cyst in the cervicodorsal region.

Exciton Transport and Andreev Reflection in a Bilayer Quantum Hall System [PDF]
, 2011 We demonstrate that counterflowing electrical currents can move through the bulk of the excitonic quantized Hall phase found in bilayer two-dimensional electron systems (2DES) even as charged excitations cannot.

Health disparities in chronic liver disease
Hepatology, EarlyView., 2022 Abstract The syndemic of hazardous alcohol consumption, opioid use, and obesity has led to important changes in liver disease epidemiology that have exacerbated health disparities. Health disparities occur when plausibly avoidable health differences are experienced by socially disadvantaged populations.

Janus kinase 2 inhibition by pacritinib as potential therapeutic target for liver fibrosis
Hepatology, EarlyView., 2022 Diagram of the activation of the profibrotic and procontractile Janus kinase 2 (JAK2)/Ras homolog family member A/Rho‐kinase pathway and the inhibition of phosphorylated JAK2 by pacritinib to inhibit hepatic stellate cell activity. Abstract Background and Aims Janus kinase 2 (JAK2) signaling is increased in human and experimental liver fibrosis with ...

Non-invasive assessment of pulsatile intracranial pressure with phase-contrast magnetic resonance imaging. [PDF]
PLoS ONE, 2017 Invasive monitoring of pulsatile intracranial pressure can accurately predict shunt response in patients with idiopathic normal pressure hydrocephalus, but may potentially cause complications such as bleeding and infection.
