Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

A Miniaturized (UWB) Bandpass Filter Using Elliptical-Ring Multi-Mode Stub-loaded Resonator (MM-SLR) [PDF]

Radioengineering, 2018
In this paper, a novel miniaturized ultra-wide¬band (UWB) band pass filter (BPF) with sharp slopes tran-sition band is reported. The UWB BPF (7.45 GHz to 19.85 GHz) consists of modified elliptical-ring and multi-mode stub-loaded resonator (MM-SLR) and ...

Detection of circulating tumor DNA in colorectal cancer patients using a methylation‐specific droplet digital PCR multiplex

Molecular Oncology, EarlyView.
We developed a cost‐effective methylation‐specific droplet digital PCR multiplex assay containing tissue‐conserved and tumor‐specific methylation markers. The assay can detect circulating tumor DNA with high accuracy in patients with localized and metastatic colorectal cancer.

Further Generalization and Approximation of Fractional-Order Filters and Their Inverse Functions of the Second-Order Limiting Form

Fractal and Fractional, 2022
This paper proposes a further generalization of the fractional-order filters whose limiting form is that of the second-order filter. This new filter class can also be regarded as a superset of the recently reported power-law filters.

A multifrequency narrow band‐pass filter

Concepts in Magnetic Resonance Part B: Magnetic Resonance Engineering, 2008
AbstractA highly selective, high‐power, multifrequency band‐pass filter is presented. The construction of the filter is based on multifrequency tuned resonators used in magnetic resonance experiments. High values of the radio‐frequency resonators' quality factors enable construction of highly selective band‐pass filters.

Monitoring of circulating tumor DNA allows early detection of disease relapse in patients with operable breast cancer

Molecular Oncology, EarlyView.
Monitoring circulating tumor DNA (ctDNA) in patients with operable breast cancer can reveal disease relapse earlier than radiology in a subset of patients. The failure to detect ctDNA in some patients with recurrent disease suggests that ctDNA could serve as a supplement to other monitoring approaches.

Scale-dependent enstrophy production rates in a turbulent boundary layer

Journal of Fluid Science and Technology, 2019
Coarse-graining is indispensable for extracting a hierarchy of vortices in fully developed turbulent flow with multiscale nature. In the present study, for a high-Reynolds-number turbulent boundary layer, we employ two simple coarse-graining methods in ...

Overview of intelligent optimization algorithm design of FIR digital filter

Dianzi Jishu Yingyong, 2021
This article summarizes the intelligent optimization algorithm of finite impulse response digital filter(FIR). The main idea of optimization design is to transform the digital filter design problem into the error function minimization problem.

SiC multilayer photonic structures with self optical bias amplification [PDF]

, 2012
Characteristics of tunable wavelength pi'n/pin filters based on a-SiC:H multilayered stacked cells are studied both experimental and theoretically. Results show that the device combines the demultiplexing operation with the simultaneous photodetection ...
