A Numerical Investigation of the Relationship Between Air Quality, Topography, and Building Height in Populated Hills

open access: yesBuildings
Urban population growth has led to increased air pollution, influenced by disrupted wind patterns and the heterogeneous distribution of pollutants. Although the relationship between urban form and air quality is well recognized, it is often examined in ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

open access: yesMolecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Material dispersion slope in optical-fibre waveguides

open access: yesElectronics Letters, 1982
The slope of the material dispersion dM/dλ at λ0, the material dispersion zero where d2n/dλ2=0, can be calculated to yield values applicable to crystals and glasses. The results, in units of ps/nm km μm, range from 217 for B2O3 and 105 for SiO2 to 9 for TI2O and 0.40 for TlI.

WDM Soliton Transmission System Using Dispersion Slope Compensators

open access: yes, 2020
-A new scheme of dispersion slope compensator by writing Bragg gratings at different positions in a dispersion compensation fiber is proposed for the wavelength division multiplexing soliton transmission system. This scheme can compensate in-line for the

Competition between spectral splitting and Raman frequency shift in negative-dispersion slope photonic crystal fiber

open access: yes, 2004
We report on the nonlinear behavior of high air-filling fraction solid-core photonic crystal fibers pumped with ultrashort pulses in the vicinity of a negative-slope zero-crossing of the group velocity dispersion.

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

On the Origin of the Variety of Velocity Dispersion Profiles of Galaxies

open access: yesThe Astrophysical Journal
Observed and simulated galaxies exhibit a significant variation in their velocity dispersion profiles. We examine the inner and outer slopes of stellar velocity dispersion profiles using integral field spectroscopy data from two surveys, SAMI (for z < 0 ...

Liquid biopsy‐based diagnostic evaluation of hypermethylated CpG sites for ovarian cancer diagnosis

open access: yesMolecular Oncology, EarlyView.
This schematic outlines the workflow from biomarker identification to duplex MethyLight assay validation for epithelial ovarian cancer diagnosis using cfDNA‐based liquid biopsy. Initial screening of hypermethylated CpG candidates (cg02957270, cg10061138 cg00480298, COL2A1) was performed in tissue using ARMS‐PCR, COBRA, qPCR and image analysis. Selected
