Electromagnetic Design of Dual Resonant Structures for Improved Sensitivity of Terahertz Label Free Bio-Sensing [PDF]

, 2010
A design is proposed exploiting full wave numerical simulation of a dual resonant structure with an aim to sense small amounts of chemical and biochemical materials. The structure is energized with free space radiation in the terahertz regime.

Design and research of an ultra-wideband metal antenna with low radar cross section

Dianzi Jishu Yingyong, 2018
An ultra-wideband metal antenna with low radar cross section is proposed. The antenna adopts the metal Vivaldi as the radiation element, and utilizes a new-type frequency selective surface structure to reduce the radar cross section within the working ...

Longitudinal circulating tumor DNA profiling in patients with advanced endometrial cancer using an off‐the‐shelf targeted NGS panel

Molecular Oncology, EarlyView.
Intratumour heterogeneity complicates precision management of advanced endometrial cancer. Circulating tumor DNA (ctDNA) offers a minimally invasive strategy to capture tumor evolution and therapeutic resistance. Here, we compare tumor‐agnostic NGS with tumor‐informed ddPCR, outlining their relative sensitivity, concordance, and clinical implications ...

Laser Polishing of Micro-Machined Microfluidic Molds [PDF]

, 2010
The objective of this paper is to explore the effective-ness of using a pulsed 1064 nm wavelength Nd:YAG laser to polish micro-machined metal molds. Polishing is desired to reduce the surface roughness of Polydimethylsiloxane (PDMS) devices cast with ...

Design Dual-Polarization Frequency Selective Rasorber Using Split Ring Resonators

IEEE Access, 2019
A novel dual-polarization frequency selective rasorber with one transmission band and two absorbing bands is proposed in this paper. The structure is composed of a lossless frequency selective surface layer and a resistive layer. The resistive layer is a

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

Molecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

The Effect of Finite Conductivity on Frequency Selective Surface Behaviour [PDF]

, 1990
The scattering problem for a Frequency Selective Surface (FSS) consisting of an array of patches or a perforated screen is solved. Both penetrable and impenetrable materials with dyadic surface impedance are considered. The problem is formulated directly

A design proposal for ultrawide band frequency selective surface

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
In this paper a three layer FSS is described which provides a ultrawide band (UWB) response. The layers use plain rectangular patches, and rectangular patches with one or two notches which provide multi-band responses; by cascading them an UWB response ...

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Numerical Study of Frequency Selective Surface by Spectral Galerkin Method [PDF]

, 2007
表面擇頻元件 (Frequency Selective Surface) 為空間中二維的週期性結構. 由於它的頻譜會在某個頻率造成全反射 (補貼型結構) 和全穿透 (孔洞型結構), 因此就像一個濾波器 (filter)一樣. 多年來, 此元件已經有許多學術上的研究. 而除了學術上的研究, 表面擇頻元件更是已經在電磁波中的許多頻段得到應用.
