Optimized Quality Factor of Fractional Order Analog Filters with Band-Pass and Band-Stop Characteristics

, 2012
Fractional order (FO) filters have been investigated in this paper, with band-pass (BP) and band-stop (BS) characteristics, which can not be achieved with conventional integer order filters with orders lesser then two.

Crosstalk between the ribosome quality control‐associated E3 ubiquitin ligases LTN1 and RNF10

FEBS Letters, EarlyView.
Loss of the E3 ligase LTN1, the ubiquitin‐like modifier UFM1, or the deubiquitinating enzyme UFSP2 disrupts endoplasmic reticulum–ribosome quality control (ER‐RQC), a pathway that removes stalled ribosomes and faulty proteins. This disruption may trigger a compensatory response to ER‐RQC defects, including increased expression of the E3 ligase RNF10 ...

Direct design method for wideband quadruplet and higher‐order bandpass filters with a pair of transmission zeros based on explicit design formulas

IET Microwaves, Antennas & Propagation
This paper presents a direct design approach and explicit design formulas for a wideband quadruplet bandpass filter with a pair of transmission zeros. A filter can be designed based on a filter schematic composed of only transmission lines and a short ...

Free-standing double-layer terahertz band-pass filters fabricated by femtosecond laser micro-machining.

Optics Express, 2017
We report on the fabrication and transmission properties of free-standing single-layer and double-layer THz bandpass filters. These filters are fabricated on aluminum foils using femtosecond laser micro-machining.

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).

Self‐packaged MISL‐based miniaturized high Q factor bandpass filter

Electronics Letters
This paper proposes a technique named self‐packaged metal integrated suspended line (MISL) to design a high Q factor bandpass filter (BPF). This unique construction simplifies the traditional suspended stripline and substrate integrated suspended line ...
