Modelling and measurement of frequency selective surfaces

, 2007
Frequency Selective Surfaces, FSS's, are used to make filters in the far infrared and submillimetre region, which can have low-pass, high-pass and band selection properties.

Tumour‐proximal deep serum proteomics identifies biomarkers associated with ovarian cancer

Molecular Oncology, EarlyView.
New biomarkers are needed for early ovarian cancer detection. Ovarian (tumour‐proximal) and peripheral vein serum from healthy women and patients with benign or malignant tumours underwent nanoparticle‐enriched deep proteomics. Ovarian serum yielded more protein identifications and revealed tumour‐reflective signatures.

Analysis Of Frequency Selective Surfaces With Ferrite Substrates

, 1995
The spectral domain Green\u27s function for the problem of frequency-selective surfaces (FSS) with ferrite substrates is developed and presented. Several results are presented to show the tunability of frequency-selective surface with ferrite substrates ...

Dual-polarized narrow-bandpass frequency-selective surfaces

, 1996
Two arrays of single-ring slots with different radii supported on either side of a thin dielectric substrate form frequency-selective surfaces (FSSs) with a very narrow bandpass transmission responses. The -10-dB bandwidths are less than 10%.

The impact of leukocyte‐associated RNA retention on platelet RNA‐based cancer detection

Molecular Oncology, EarlyView.
Platelets carry RNA signals that may help detect cancer, but platelet samples can also retain RNA from white blood cells. We found that this retained white blood cell signal did not significantly affect machine learning cancer classification, suggesting that the cancer‐related RNA signal in platelets is largely independent of leukocyte‐associated RNA ...

Multiband frequency selective surfaces with a modified multifractal cantor geometry

Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2014
Self-affine property of a modified multifractal Cantor geometry is exploited to design frequency selective surfaces (FSS) with multiband response. The main advantage of the proposed structure is to design multiband FSS with multiple frequency ratios ...

Rings as elements for frequency selective surfaces

, 1981
Arrays of simple rings on close packed square or triangular lattices are useful frequency selective surfaces for reflector antennas. Reflection bandwidths of about 26 per cent and transmission/reflection band ratios of 3:1 are readily attainable for ...

An outer membrane vesicle‐associated two‐track model for enterotoxigenic Bacteroides fragilis oncogenesis

Molecular Oncology, EarlyView.
Enterotoxigenic Bacteroides fragilis is a gut bacterium linked to bowel cancer. We propose that its toxin acts along two routes: at the cell surface, cutting the adhesion protein E‐cadherin and triggering inflammation; and inside the cell, delivered by bacterial vesicles, switching on NOD1 and cancer stem cell programs.
