Light intensity-regulated glycogen synthesis and pollutant removal in microalgal-bacterial granular sludge for wastewater treatment.

As light intensity plays a pivotal role in the microalgal-bacterial granular sludge (MBGS) process, understanding its impact on system performance and energy dynamics is essential. This study investigated the effects of varying light intensities (20, 100, 200, and 300 μ mol/m²/s) on the performance of MBGS in urban wastewater treatment, with a particular focus on glycogen accumulation and pollutant removal. The results demonstrated that light intensity significantly influenced microbial community structure, glycogen accumulation, and pollutant removal efficiency.

CsIREH1 phosphorylation regulates DELLA protein affecting plant height in cucumber (Cucumis sativus).

Plant height is a critical agronomic trait that affects crop yield, plant architecture, and environmental adaptability. Gibberellins (GAs) regulate plant height, with DELLA proteins acting as key repressors in the GA signaling pathway by inhibiting GA-induced growth. While DELLA phosphorylation is essential for regulating plant height, the precise mechanisms underlying this process remain incompletely understood.

An Entropy Weighted Nonnegative Matrix Factorization Algorithm for Feature Representation.

Nonnegative matrix factorization (NMF) has been widely used to learn low-dimensional representations of data. However, NMF pays the same attention to all attributes of a data point, which inevitably leads to inaccurate representations. For example, in a human-face dataset, if an image contains a hat on a head, the hat should be removed or the importance of its corresponding attributes should be decreased during matrix factorization.

[Brain functional network reconstruction based on compressed sensing and fast iterative shrinkage-thresholding algorithm].

The construction of brain functional network based on resting-state functional magnetic resonance imaging (fMRI) is an effective method to reveal the mechanism of human brain operation, but the common brain functional network generally contains a lot of noise, which leads to wrong analysis results. In this paper, the least absolute shrinkage and selection operator (LASSO) model in compressed sensing is used to reconstruct the brain functional network. This model uses the sparsity of -norm penalty term to avoid over fitting problem.

The WUSCHEL-related homeobox1 gene of cucumber regulates reproductive organ development.

The WUSCHEL-related homeobox1 (WOX1) transcription factor plays an important role in lateral growth of plant organs; however, the underlying mechanisms in the regulation of reproductive development are largely unknown. Cucumber (Cucumis sativus) has separate male and female flowers, facilitating the study of the role of WOX1 in stamen and carpel development. Here, we identified a mango fruit (mf) mutant in cucumber, which displayed multiple defects in flower growth as well as male and female sterility.
