A 24-GHz CMOS Front-End [PDF]

open access: yes, 2004
This paper reports the first 24-GHz CMOS front-end in a 0.18-µm process. It consists of a low-noise amplifier (LNA) and a mixer and downconverts an RF input at 24GHz to an IF of 5 GHz.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

An unusual combination of Unilateral Orbital Plexiform Neurofibroma in a patient with oculocutaneous albinism

open access: yesIndian Journal of Ophthalmology, 2014
A 70-year-old female patient presented with proptosis of right eye for the past 15 days and defective vision in both eyes since birth. She was found to have eccentric painful proptosis of right eye along with features of oculocutaneous albinism ...

Gravito-magnetic instabilities in anisotropically expanding fluids

open access: yes, 2008
Gravitational instabilities in a magnetized Friedman - Robertson - Walker (FRW) Universe, in which the magnetic field was assumed to be too weak to destroy the isotropy of the model, are known and have been studied in the past.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Hemodynamic Quantitative Analysis Based on Doppler Ultrasound for Arteriovenous Shunt Stenosis Screening

open access: yesIEEE Access, 2019
Clinically, arteriovenous shunt (AVS) stenosis results in turbulent and pulsatile flow because of high resistance and pressure within a narrowed space inside a stenotic access.

Synthesis and characterization of bulk and thin film antimony-selenium phase change alloys

open access: yes, 2008
Phase change alloys have recently gained increasing attention due to their application in developing phase change random memory (PRAM) devices, as Flash memory based devices are rapidly approaching their technological limitations.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.
