Misalignment Calculation on Off-Axis Telescope System via Fully Connected Neural Network
Pubblicazione 2020-01-01TestoOn the process of alignment for pupil off-axis telescope system, the determination of decentering and tilt misalignments is a key step. In this paper, we proposed a new method which adopts the fully connected neural network (FCNN) as a fitting tool to establish the nonlinear mapping relation between...

Experimental Study of a Multispectral Piston Sensing Technology
Pubblicazione 2019-01-01TestoNowadays giant segmented telescopes and multiaperture telescopes have grown out of the quest for high-resolution observations in astronomy. One of the major issues is the phasing of such telescopes. A concept of multispectral piston sensing technology is, therefore, re-examined and studied experimen...

Transcriptional profile of gene clusters involved in the methylerythritol phosphate pathway in Bacillus subtilis 916
Pubblicazione 2019-03-01TestoThe methylerythritol phosphate pathway is responsible for the biosynthesis of terpenoids, the largest class of secondary metabolites. Although the structures and functions of the proteins involved in this pathway have been well studied in Bacillus subtilis, only a few studies have reported the trans...

Identification of similar transcriptional regulatory mechanisms in multiple cry genes in Bacillus thuringiensis HD12
Pubblicazione 2017-01-01TestoBacillus thuringiensis subspecies morrisoni strain HD12, whose genome harbors multiple insecticidal protein-encoding genes, includes eight cry genes, as indicated by genome sequencing. This strain produces crystals that are toxic to lepidopteran species. These crystal inclusions were purified by suc...

Inheritance and molecular characterization of resistance to AHAS-inhibiting herbicides in rapeseed
Pubblicazione 2017-11-01TestoRapeseed is a very important oil crop in China; however, its production is challenging due to the absence of effective weed management strategies. This is predominantly because of a shortage of herbicide resistance genes. Acetohydroxyacid synthase (AHAS) herbicides inhibit AHAS, a key enzyme involve...

Induced Treg‐Derived Extracellular Vesicles Suppress CD4+ T‐Cell‐Mediated Inflammation and Ameliorate Bone Loss During Periodontitis Partly Through CD73/Adenosine‐Dependent Immunom...
Pubblicazione 2025-07-01TestoABSTRACT Regulatory T cell (Treg)‐derived extracellular vesicles (EVs) represent a contact‐independent mechanism by which Tregs suppress dysregulated immune responses. These EVs carry diverse immunomodulatory molecules, including CD73, an ectoenzyme that hydrolyses AMP into adenosine. Adenosine subs...
