A multi-band internal antenna [PDF]

2011 Loughborough Antennas & Propagation Conference, 2011
A compact multi-band internal antenna has been proposed for the application of global positioning system (GPS), and wireless local area network (WLAN). The antenna comprises a planar inverted-F antenna (PIFA) in conjunction with a parasitic element.

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.

TSV Antennas for Multi-Band Wireless Communication

IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2020
On-chip wireless links offer improved network performance due to long distance communication, additional bandwidth, and broadcasting capabilities of antennas. This work challenges the on-chip antenna design conventions, and pushes toward a Through-Silicon Via-based antenna design called TSV_A that establishes multi-band wireless communication through ...

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

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Magnetically tunable multi-band near-field radiative heat transfer between two graphene sheets

, 2018
Near-field radiative heat transfer (NFRHT) is strongly related with many applications such as near-field imaging, thermos-photovoltaics and thermal circuit devices. The active control of NFRHT is of great interest since it provides a degree of tunability
