Abstract Here, we combined the merits of emergent excitation‐dependent (ExD) emission and circularly polarized luminescence to develop an (ExD CPL) material showing unique features. A series acylhydrazones based on a chiral tartaric skeleton was designed found self‐assemble into helical nanostructures through non‐covalent bonds. The assemblies showed ExD CPL due cooperation chirality transfer excited state intramolecular proton (ESIPT). Remarkably, not only wavelength could be tuned by...
Tracking trajectories of the unconnected vehicles contributes to improvement traffic efficiency and safety. However, effects occlusions on accuracy reliability tracking results are nonnegligible. To address this issue, a modified multiple objects algorithm was proposed reduce loss caused by occlusions. The based detection results, in which motion states detected were determined. Further, Kalman filter employed predict trajectories, each trajectory uniquely matched object labeled with...
Bioethanol from lignocellulosic biomass is a promising and sustainable strategy to meet the energy demand be carbon neutral. Nevertheless, damage of lignocellulose-derived inhibitors microorganisms still main bottleneck. Developing robust strains critical for ethanol production. An evolved strain with stronger tolerance formate acetate was obtained after adaptive laboratory evolution (ALE) in formate. Transcriptional analysis conducted reveal possible resistance mechanisms weak acids, fdh...
l-Alanyl-l-glutamine (Ala-Gln) represents the great application potential in clinic due to unique physicochemical properties. A new approach was developed synthesize Ala-Gln by recombinant Escherichia coli OPA, which could overcome disadvantages of traditional chemical synthesis. Although satisfactory results had been obtained with E. endotoxin and use multiple antibiotics along toxic inducer brought biosafety hazard for clinical Ala-Gln. In this study, safer host Pichia pastoris applied as...
Many experiments of object-based image analysis have been conducted in remote sensing classification. However, they commonly used high-resolution imagery and rarely focused on suburban area. In this research, with the Landsat-8 imagery, classification a area via approach is achieved using four classifiers, including decision tree (DT), support vector machine (SVM), random trees (RT), naive Bayes (NB). We performed feature selection at different sizes segmentation scale evaluated effects...

Concerns regarding the increasing carbon dioxide (CO 2 ) concentration has aroused global interest in renewable fuels and conversion of CO into chemicals.
Of all anthropogenic pollutants, nitrogen dioxide (NO2) has the most negative effect on atmospheric chemistry. In this study, measurements of tropospheric column NO2 obtained from ozone monitoring instrument (OMI) are used to investigate temporal and spatial dynamics NO2. Temporal distributions concentrations OMI over Beijing-Tianjin-Hebei (Jing-Jin-Ji) region 2007 2016 presented, annual changes trends in seasonal cycle shown. Annual amounts found firstly increase then decrease, where after...
We examine the swelling and dissolution of hydrogels cross-linked by a combination physical chemical junctions, focusing on technologically important DNA- "bis"-cross-linked polyacrylamide architecture. A theoretical model to account for binding energy cross-links their coupling elastic free identifies network characteristics that control access swollen dissolved states. The provides basis interpreting nonswelling, swelling, states reported in literature, accomplished with specific polymer...
l-Alanyl-l-glutamine (Ala-Gln) is a widely used value-added dipeptide whose production relies heavily upon an efficient biocatalyst. The currently available yeast biocatalysts that express α-amino acid ester acyltransferase (SsAet) possess relatively low activity, which may be attributed to glycosylation. Here, promote SsAet activity in yeast, we identified the N-glycosylation site as Asn residue at position 442 and subsequently eliminated negative effect of on by removing artificial native...
Abstract The combustion instability in a propulsion system is ubiquitous problem. radial baffles usually installed on the injector faceplate eliminate (acoustic pressure oscillation) system. In this article, longitudinal are inner surface of combustor wall to control instabilities. first-order and second-order tangential modes induced experiments. effects parameters baffle acoustic oscillation cylindrical investigated. effect nozzle has been systematically It concluded that eigen-frequency...
