Ultra-Narrow-Band Filter Based on High Q Factor in Metallic Nanoslit Arrays

Sensors, 2020
Here we propose a novel high Q ultra-narrow-band filter in the optical regime. Multiple high Q resonances are achieved in ultra-thin metallic nanoslit arrays on stacked low index–high index dielectric (LID–HID) substrate.

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Gravitational complexity factor of anisotropic polytropes in coincident gauge $$f(\mathbb {Q})$$ f ( Q ) gravity

European Physical Journal C: Particles and Fields
This work presents a novel characterization of complexity for gravitationally bound astrophysical configurations arising from two factors: (i) inhomogeneity and (ii) anisotropy in the complex arrangement of stellar structures. For this purpose, we employ

On factorization of $q$-difference equation for continuous $q$-ultraspherical polynomials

, 2007
We prove that a customary Sturm-Liouville form of second-order $q$-difference equation for the continuous $q$-ultraspherical polynomials $C_n(x;β| q)$ of Rogers can be written in a factorized form in terms of some explicitly defined $q$-difference operator ${\mathcal D}_x^{β, q}$. This reveals the fact that the continuous $q$-ultraspherical polynomials

Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

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

Molecular 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

Coupling mechanism of a loop‐type ground radiation antenna

ETRI Journal, 2019
The coupling mechanism of a loop‐type ground radiation antenna is investigated in this paper. We use the equivalent circuit model of the antenna and a full‐wave simulation to explain the coupling mechanism of the antenna.

The K-meson form factor and charge radius: linking low-energy data to future Jefferson Laboratory measurements

European Physical Journal C: Particles and Fields, 2017
Starting from a successful model of the $$\pi $$ π -meson electromagnetic form factor, we calculate a similar form factor, $$F_{K}(Q^{2})$$ F K ( Q 2 ) , of the charged K meson for a wide range of the momentum transfer squared, $$Q^{2}$$ Q 2 .

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Unveiling the tradeoff between device scale and surface nonidealities for an optimized quality factor at room temperature in 2D MoS2 nanomechanical resonators

Microsystems & Nanoengineering
A high quality (Q) factor is essential for enhancing the performance of resonant nanoelectromechanical systems (NEMS). NEMS resonators based on two-dimensional (2D) materials such as molybdenum disulfide (MoS2) have high frequency tunability, large ...
