The generalized spectral subtraction algorithm (GBSS), which has extraordinary ability in background noise reduction, is historically one of the first approaches used for speech enhancement and dereverberation. However, not been applied to de-noise room impulse response (RIR) extend reverberation decay range. application GBSS this study stated as an optimization problem, that is, subtracting le...

We report a label-free fluorescent strategy to study the distribution and stability of DNA origami nanostructures in live, cellular systems, using carbazole-based biscyanine as a probe molecule which has the characteristic property of restriction of intramolecular rotation (RIR) induced emission.

Formation of T-Hg(2+)-T complexes changes the configuration of a single-stranded DNA, leading to enhanced fluorescence of an anchored cyanine-based probe that displays restricted intramolecular rotation (RIR)-induced emission. This label-free system can be used as a sensor for mercury ions with a detection limit of 4 nM.

Stepwise locking of phenyl rings of tetraphenylethene increases the emission efficiency of luminogen solutions gradually, thus verifying the restriction of intramolecular rotation (RIR) mechanism of the aggregation induced emission phenomenon. The emission of the luminogen with one "O" bridge could be tuned reversibly in solid state through repeated heating and grinding.

In this paper we consider low-rank estimation of room impulse responses (RIRs). Inspired by a physics-driven room-acoustical model, propose an estimator RIRs that promotes structure for matricization, or reshaping, the estimated RIR. This prior acts as regularizer inverse problem estimating RIR from input-output observations, preventing overfitting and improving accuracy. As directly enforcing ...

Naphthylhydrazone derivative, 1-[(2-Hydroxy-4,6-dimethoxy-benzylidene)-hydrazonomethyl]-naphthalen-2-ol (H2L), an Aggregation Induced Emission (AIE) active probe emerges out as a promising solid-state emitter upon exercising restricted intramolecular rotation (RIR) in ordered J-type self-assembly and...

An understanding of the climate conditions governing spatial variation in the reproductive performance of plants can provide important information about the factors characterizing plant community structure, especially in the context of climate change. This study focuses on the effect of climate on the sexual reproductive output of Dactylis glomerata L., a perennial grass species widely distribu...
