Novel Reconnection-Less Reconfigurable Filter Design Based on Unknown Nodal Voltages Method and Its Fractional-Order Counterpart

Elektronika ir Elektrotechnika, 2019
A novel solution of reconnection-less electronically reconfigurable filter is introduced in the paper. The filter is designed based on unknown nodal voltages method (MUNV) using operational transconductance amplifiers (OTAs) and variable gain amplifier ...

Discrete universal filtering through incremental parsing [PDF]

Data Compression Conference, 2004. Proceedings. DCC 2004, 2004
In the discrete filtering problem, a data sequence over a finite alphabet is assumed to be corrupted by a discrete memoryless channel. The goal is to reconstruct the clean sequence, with as high a fidelity as possible, by way of causal processing of the noisy sequence alone, with the reconstruction at time t depending only on noisy observations ...

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

FEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

New Universal Filter Using Two Current-Feedback Amplifiers

Active and Passive Electronic Components, 1997
A new universal voltage-mode second-order filter circuit is presented. The circuit has three inputs and one low-impedance output and can realize all the standard filter functions; lowpass, highpass, bandpass, notch, and allpass, without changing the ...

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

New Universal One-Input Five-Output Current-Mode Filter Using Current-Conveyors

Active and Passive Electronic Components, 1995
A new universal active current-mode filter with single input and five outputs is presented. The proposed filter avoids the use of feedback in any part of the circuit and uses only grounded resistors and grounded capacitors.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Electronically reconfigurable universal filter based on VDTAs [PDF]

2018 28th International Conference Radioelektronika (RADIOELEKTRONIKA), 2018
The proposed filter extends features of the previously presented Voltage Differencing Transconductance Amplifiers (VDTAs)-based frequency filter. It brings the new advantage of an electronic reconfiguration of its transfer. The proposed structure provides reconnection-less change between low-pass, band-pass, high-pass, band-stop and all-pass transfer ...
