Variant of the charged system search algorithm for the design of optimal linear phase finite impulse response filters

open access: yesAutomatika, 2019
Digital signal filtering is one of the prime area which is frequently used in practical applications. In the class of digital filters, the prominent filters include – filters with finite impulse response (FIR) and filters with infinite impulse response ...

Microstrip band-pass filter with −67 dB stop band up to 8.8 times the pass-band center frequency

open access: yes, 2017
Step-impedance resonators and step-impedance capacitor coupling pads are introduced to microstrip band-pass filters to suppress spurious stop-band responses up to the ninth order, thereby providing a very wide stop band.

Design of sharp-cut-off low-pass filters with ripples in the pass-band [PDF]

open access: yes, 1975
For the design of sharp-cut-off low-pass filters, derived from all-pole Chebyshev filters, one needs to determine n, the order of the filter; m, the order of finite zeros; ¿0, the location of the zeros; and ¿, the ripple controlling

Purification and preparation of Marchantia polymorpha Auxin Response Factor 2 for phase separation studies

open access: yesFEBS Open Bio, EarlyView.
We describe detailed protocols for the purification and preparation of Marchantia polymorpha Auxin Response Factor 2 (MpARF2). This protein is fused to an MBP solubility tag and an mNG fluorescent tag and is purified from Escherichia coli. The presented procedures make it possible to study MpARF2 assemblies, which could arise from phase separation ...

Identification and characterisation of calcitonin receptor isoforms expressed in glioblastoma derived glioma stem and U‐87 MG cells

open access: yesFEBS Open Bio, EarlyView.
Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Longer-term effects of monetary growth on real and nominal variables, major industrial countries, 1880-2001 [PDF]

open access: yes
: We study how fluctuations in money growth correlate with fluctuations in real and nominal output growth and inflation. We pick cycles from each time series that last 2 to 8 (business cycles) and 8 to 40 (longer-term cycles) years, using band-pass ...

The C‐terminal truncated splicing variant of NK1R negatively modulates substance P‐stimulated NK1R signaling

open access: yesFEBS Open Bio, EarlyView.
The neurokinin 1 receptor exists as full‐length (NK1L) and C‐terminally truncated (NK1S) splice variants. We show that NK1S heterodimerizes with NK1L, impairing Gαq coupling and Ca2+ mobilization while enhancing β‐arrestin1 recruitment. NK1S suppresses substance P‐driven gene expression and cell migration, revealing NK1S as an endogenous biased ...

On a Design of Narrowband FIR Low-Pass Filters

open access: yes, 2009
Stearns and David (1996) states that “for many diverse applications, information is now most conveniently recorded, transmitted, and stored in digital form, and as a result, digital signal processing (DSP) has become an exceptionally important modern ...

TRPML1 agonist ML‐SA5 attenuates pulmonary fibroblast activation by suppressing mTOR and restoring autophagic flux

open access: yesFEBS Open Bio, EarlyView.
TGF‐β1 stimulation downregulates lysosomal channel TRPML1 in pulmonary fibroblasts. The TRPML1 agonist ML‐SA5 suppressed fibroblast‐to‐myofibroblast activation and collagen production. Mechanistically, ML‐SA5 inhibited mTOR phosphorylation, restored autophagic flux, and its effects were enhanced by rapamycin (mTOR inhibitor) and reversed by MHY1485 ...
