A Current Mode Design of Fractional Order Universal Filter

open access: yesAdvances in Electrical and Computer Engineering, 2019
In this paper, low-voltage active elements based a general filter topology, which provides fractional order low-pass, high-pass, band-pass and band-reject filter responses at the same circuit, is introduced.

A new power line conditioner for harmonic compensation in power systems [PDF]

open access: yes, 1995
This paper proposes a new power line conditioner consisting of two small rating series active filters and a shunt passive filter. The power line conditioner aims at a general filtering system which will be installed at the point of common coupling in a ...

Aggressive prostate cancer is associated with pericyte dysfunction

open access: yesMolecular 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).

Electrochemical carbon nanotube filters for water and wastewater treatment

open access: yesNanotechnology Reviews, 2016
Electrochemically active carbon nanotube (CNT) filters have been developed as a highly efficient technology for water and wastewater treatment during the last few years. CNT filters have been widely used to adsorb chemical and biological contaminants due

Current-mode Biquadratic Universal Filter Design with Two Terminal Unity Gain Cells [PDF]

open access: yes, 2012
A grounded parallel lossy active inductor and two current-mode (CM) universal filters are presented in this paper. All the circuits use two voltage followers (VFs) and a current follower (CF).
