SPEECH SEPARATION BY MODIFIED DEEP NON-LINEAR FILTERING MODEL

Електроніка та інформаційні технології
Background. Automatic Speech Recognition (ASR) systems in single-channel experimental setups perform poorly in real-world scenarios when several talkers are placed near a microphone.

Adaptive Unscented Kalman Filter for Target Tracking with Unknown Time-Varying Noise Covariance

Sensors, 2019
The unscented Kalman filter (UKF) is widely used to address the nonlinear problems in target tracking. However, this standard UKF shows unstable performance whenever the noise covariance mismatches.

Classification of digital non-linear filters by discrete convolutions

Известия высших учебных заведений. Поволжский регион:Технические науки, 2022
Background. In the field of digital signal processing, there are many problems that can not be solved with traditional linear filtering methods. In particular, the use of linear filtering does not allow separating signal from the noise in the case when

A study on input noise second-order filtering and smoothing of linear stochastic discrete systems with packet dropouts

Advances in Difference Equations, 2020
We investigate non-Gaussian noise second-order filtering and fixed-order smoothing problems for non-Gaussian stochastic discrete systems with packet dropouts.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

The optimization of a class of non-linear filters

Proceedings of the IEE Part C: Monographs, 1960
Some time invariant non-linear filters of Zadeh's class ? are optimized. A method is proposed for the physical realization of these filters as multipath structures, which consist of, in general, an orthonormal set of non-linear zero memory polynomial functions, each of which is followed by a linear memory network in cascade.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

FEBS Letters, EarlyView.
Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

A Probabilistic Perspective on Gaussian Filtering and Smoothing [PDF]

, 2010
15.07.13 KB. Ok to add report to Spiral.We present a general probabilistic perspective on Gaussian filtering and smoothing. This allows us to show that common approaches to Gaussian filtering/smoothing can be distinguished solely by their methods of ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...
