Interference-Normalised Least Mean Square Algorithm [PDF]

IEEE Signal Processing Letters, Vol. 14, No 12, pp. 988-991, 2007, 2016
An interference-normalised least mean square (INLMS) algorithm for robust adaptive filtering is proposed. The INLMS algorithm extends the gradient-adaptive learning rate approach to the case where the signals are non-stationary. In particular, we show that the INLMS algorithm can work even for highly non-stationary interference signals, where previous ...

DNA-coated microcrystals [PDF]

, 2005
Coprecipitation leads to self-assembly of bioactive DNA on the surface of salt, sugar or amino-acid crystals and provides a rapid inexpensive immobilization method suitable for preparing dry-powder formulations of nucleic acids, useful for storage ...

The Uptake and Release of Amino Acids by Staphylococcus aureus at Mid-Exponential and Stationary Phases and Their Corresponding Responses to Changes in Temperature, pH and Osmolality

Frontiers in Microbiology, 2020
Staphylococcus aureus is an important pathogen that is associated with nosocomial infections, as well as food poisoning. This bacterium is resistant to antimicrobial agents and can survive in a wide range of environmental conditions.

Branched-chain amino acids linked to depression in young adults

Frontiers in Neuroscience, 2022
Depression is a heterogeneous mental health problem affecting millions worldwide, but a majority of individuals with depression do not experience relief from initial treatments. Therefore, we need to improve our understanding of the biology of depression.

Bandwidth Extension of Narrowband Speech for Low Bit-Rate Wideband Coding [PDF]

Proc. IEEE Speech Coding Workshop (SCW), 2000, pp. 130-132, 2016
Wireless telephone speech is usually limited to the 300-3400 Hz band, which reduces its quality. There is thus a growing demand for wideband speech systems that transmit from 50 Hz to 8000 Hz. This paper presents an algorithm to generate wideband speech from narrowband speech using as low as 500 bits/s of side information.

Enabling Aromatic Hydroxylation in a Cytochrome P450 Monooxygenase Enzyme through Protein Engineering

Chemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022
Structural and biochemical data demonstrate that 4‐phenylbenzoic acid binds within the active site of the cytochrome P450 monooxygenase CYP199A4, but no oxidation occurs. Protein engineering and molecular dynamic simulations establish that aromatic oxidation is enabled by a subtle shift of the substrate relative to the heme, thus improving our ...

Perceptually-Motivated Nonlinear Channel Decorrelation For Stereo Acoustic Echo Cancellation [PDF]

Proceedings of Joint Workshop on Hands-free Speech Communication and Microphone Arrays (HSCMA), pp. 188-191, 2008, 2016
Acoustic echo cancellation with stereo signals is generally an under-determined problem because of the high coherence between the left and right channels. In this paper, we present a novel method of significantly reducing inter-channel coherence without affecting the audio quality.
