Strong coupling and long-range collective interactions in optomechanical arrays [PDF]

open access: yes, 2012
We investigate the collective optomechanics of an ensemble of scatterers inside a Fabry-Perot resonator and identify an optimized configuration where the ensemble is transmissive, in contrast with the usual reflective optomechanics approach.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

Review of specific antenna configurations: An estimate of cost and performance versus frequency for a simple (10 Lambda)-2 clear-air radar antenna array [PDF]

open access: yes, 1983
The building of operational clear air radar wind profilers is discussed. The choice of operating frequency and antenna configuration for these profilers is examined.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Influence of array configuration on MIMO channel capacity [PDF]

open access: yes2008 IEEE Antennas and Propagation Society International Symposium, 2008
The use of multiple antennas at each side of the radio link has demonstrated an increase in terms of data bit rate and spectral efficiency [1]. Due to this, different techniques such as spatial multiplexing and space-frequency-time techniques are being applied to MIMO (Multiple-Input Multiple-Output) systems.

Differential regulation of ZFAS1 splice variants by endoplasmic reticulum stress in hepatocyte cell lines

open access: yesFEBS Open Bio, EarlyView.
ZFAS1 is a lncRNA promoting cell proliferation and migration, exhibiting high expression in various cancers. It is conserved, widely expressed, and produces multiple splice variants with unclear roles. We identified several splice variants in hepatocyte models, and found that inhibiting or suppressing regulators of the unfolded protein response (PERK ...

Design and Analysis of Complementary Split Ring Resonator Based Low Profile Antenna Using Lightweight Polymers for Wireless, Radar and Satellite Communication [PDF]

open access: yesMechanics of Advanced Composite Structures
The article introduces a novel antenna design aimed at addressing the demands of communication technologies. The antenna configuration involves a circular patch coupled with a coplanar waveguide (CPW) and incorporates circular split-ring resonators (SRR)
