Integrated kerr comb-based reconfigurable transversal differentiator for microwave photonic signal processing

open access: yes, 2017
An integrated reconfigurable transversal differentiator is achieved based on an integrated nonlinear micro-ring resonator. The RF responses of different orders of differentiation are experimentally characterized.

On the number of A-transversals in hypergraphs

open access: yesPeriodica Mathematica Hungarica
AbstractA set S of vertices in a hypergraph is strongly independent if every hyperedge shares at most one vertex with S. We prove a sharp result for the number of maximal strongly independent sets in a 3-uniform hypergraph analogous to the Moon-Moser theorem.

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

open access: yesMolecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Transversal of disjoint convex polygons

open access: yes, 2003
A report on the transversal of disjoint convex polygons was presented. The existence of an ω(nlogn) lower bound for finding a transversal of n homothets of a circle was shown.

Guided Waves and Transverse Fields: Transverse to what?

open access: yesIEEE Antennas and Propagation Magazine, 2008
This paper describes two-dimensional TE (transverse electric) and TM (transverse magnetic) types of wave representation. These fields are of interest as long as waves are guided and can be decomposed into transverse and longitudinal components. Guided-wave propagation problems, such as transmission lines, waveguides with rectangular and/or circular ...

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Colourful transversal theorems

open access: yes, 2008
We prove the colourful versions of three clasical transversal theorems: The Katchalski-Lewis Theorem "T(3) implies T-k", the "T(3) implies T" Theorem for well distributed sets, and the Goodmann-Pollack Transversal Theorem for ...

Tumor B‐cell infiltration in platinum‐treated advanced muscle‐invasive urothelial carcinoma

open access: yesMolecular Oncology, EarlyView.
Bladder tumors with higher pretreatment memory B‐cell infiltration were linked to longer survival after cisplatin chemotherapy, but not carboplatin. These tumors also showed more organized immune structures (tertiary lymphoid structures) and a shared pro‐inflammatory B‐cell‐rich community, suggesting that memory B cells may help identify patients most ...
