In the past decades, silicon photonic integrated circuits (PICs) have been considered a promising approach to solve bandwidth bottleneck in optical communications and interconnections. Despite rapid advances, large-scale PICs still face series of technical challenges, such as large footprint, high power consumption, lack memory, resulting from active tuning methods used control waves. These cha...

Aiming at rolling bearing fault diagnosis, the collected vibration signal contains complex noise interference, and one-dimensional information cannot be used to fully mine data features of problem. This paper proposes a diagnosis method based on SVD-GST combined with Vision Transformer. Firstly, is preprocessed reduce using singular value decomposition (SVD) obtain more accurate useful signal. ...

Kano et al. proved that if P0, P1, . . . , Pk−1 are pairwise disjoint collections of points in general position, then there exist spanning trees T0, T1, . . . , Tk−1, of P0, P1, . . . , Pk−1, respectively, such that the edges of T0 ∪ T1 ∪ · · · ∪ Tk−1 intersect in at most (k − 1)n − k(k − 1)/2 points. In this paper we show that this result is asymptotically tight within a factor of 3/2. To prov...

several cell lines (18) of poorly differentiated rat ascites hepatomas which grown intraperitoneally were analyzed with respect to their mrna levels of gst-p and albumin. the expression of albumin was dramatically decreased and became undetectable in all of the examined hepatomas compared with normal rat liver. the gst-p mrna level in the hepatomas was correlated with their ability for formatio...

Currently much attention is focused on glutathione S transferase (GST)-induced suppression of apoptosis. The objective of our studies was therefore to see if GST isoenzymes rescue photoreceptors in retinal explants from rd1/rd1 mice, in which photoreceptors degenerate rapidly. Eyes from C3H rd1/rd1 and / mice were collected at various time points between postnatal day (PN) 2 and PN28. Localizat...

Glutathione S-transferase mu2 (GST-M2) is a phase II detoxification enzyme. Low expression of GST-M2 in lung cancers is due to hypermethylation of its promoter. Lung cancer with the GST mu-null genotype is associated with shorter survival. However, a correlation between GST-M2 and important clinical parameters, as well as the migration of GST-M2-defective cells in lung cancer, has not been esta...

This study examined the effect of an antioxidant intervention in biomarkers of inflammation and oxidative stress (OS) in the blood of Down syndrome (DS) children and teenagers during four different stages. A control group was composed by healthy children (n=18), assessed once, and a Down group composed by DS patients (n=21) assessed at the basal period (t0), as well as after 6 months of antioxi...

BACKGROUND It has been suggested that the genetically determined deficiency of glutathione S transferase (GST) enzymes involved in the detoxification of environmental tobacco smoke (ETS) components may contribute to the development of asthma. METHODS A large population of German schoolchildren (n = 3054) was genotyped for deficiencies of the GST isoforms M1 and T1. The association between GST...

glutathione s-transferase (gst) activity pattern was determined in tolerant (cv. sumai#3) and susceptible (cv. falat) wheat heads inoculated with fusarium graminearum, the causal agent of head scab disease (fhb), during various developmental stages. gst specific activity exhibited a transient pattern in sumai#3 reaching a maximum level at the milk stage and declining thereafter. gst level in su...
