Thrombotic cerebro-cardiovascular diseases are the leading causes of disability and death worldwide. However, current drug therapeutics compromised by narrow therapeutic windows, unsatisfactory thrombolysis effects, severe bleeding events, high recurrence rates. In this study, we exploit a self-propelling nano-penetrator with fuel loading controllable motion features, which is molecularly co-assembled using photothermal photosensitizer (DiR) photothermal-activable NO donor (BNN6). The...
The β-H elimination is a crucial elementary step in transition-metal catalysis, but controlling the stereochemistry of this process has been underdeveloped. limited works reported so far have only focused on creating axial chirality allenes, and no report able to build central using asymmetric elimination. In study, we Trost ligand-enabled enantioselective desymmetric reaction from π-allyl-Pd. This transformation provides rapid access cyclohexenes bearing C4-remoted stereocenter, total...
Three different herbivore grazing assemblages, namely, yak (YG), Tibetan sheep (SG) and co-grazing (MG), are practiced in alpine meadows on the Qinghai-Tibetan Plateau (QTP), but effects of assemblages soil microbes relatively unknown. The microbial community plays an important role functional stability grassland ecosystems. Therefore, it is to understand how structure ecosystems changes under ensure their sustainable development. To fill this gap, a field study was carried out investigate...
This article addresses the sustainable traceability issue in food supply chain from sourcing perspective which consumer willingness to pay for is considered. There are two supplier types: traceable suppliers, costly but can carry a precise recall safety events, and non-traceable less expensive may suffer higher cost events. A portion of consumers display consciousness, willing premium products. Four possible strategies transparent three nontransparent identified we determine when each...
The purpose of this study was to investigate the differences in meat quality between two local breeds Tibetan sheep, White sheep and Black Qinghai, search for metabolic mechanisms that produce by analyzing differential metabolites key rumen microorganisms. results showed one breed, SG73, superior other (WG). Further investigation identified composition muscle microorganisms breeds. It also regulates tenderness, water retention, fat content AA FA through major pathways, metabolism...
The relation between trace element levels in drinking water and cognitive function was investigated a population-based study of elderly residents (n = 1, 016) rural China 1996–1997. Cognitive measured using Chinese translation the Community Screening Interview for Dementia. A mixed effects model used to evaluate effect each elements on while adjusting age, sex, educational level. Several examined had significant when they were assessed univariate context. However, after adjustment other...
As more interdependent relationship between suppliers and their immediate buyers in current supply chain networks (SCNs), any disruption of SCNs can bring dramatic threatening to the entire networks. The purpose this paper is present a network-design tool that be used by managers/decision-makers managing risks forge resilient meat-food SCNs. In paper, model based on multisupplier constructed enhance survivability resilience after happened using mixed-integer stochastic programming method....
The traditional method does not accurately select the ecological landscape pattern index of urban wetland, which leads to problems low accuracy and long planning time, in order solve this problem, an wetland model based on MSPA analysis is constructed. By analyzing basic components landscape, such as patch density, aggregation index, dispersion average fractal dimension, segmentation, shape spread Shannon diversity used extract core area, area ring wetland. According extraction results,...
Edge detection is a core technology in image processing and recognition. Because classical edge operators such as Roberts, Sobel Canny operator are sensitive to noise, traditional algorithm based on mathematical morphology insufficient for complex features, this paper proposes multi-structure multi-scale morphological adaptive fusion that can reasonably consider noise reduction preserve the detailed information. Finally, experiment results indicate novel ensures continuity, integrity,...
Abstract This paper investigates two pricing policies against supply disruption for a chain with vertical product differentiation as well an external competitor who sells similar products. Market‐chasing policy aims at minimizing the market share loss, while profit‐chasing to minimize profit loss under disruption. Stackelberg games are established analyze equilibrium behaviors both It is shown that effectiveness of market‐chasing depends on competitive power manufacturer and competitor,...
Iris recognition is a robust biometric technology. This paper proposes novel local descriptor for bovine iris recognition, named Gabor Weber (GWLD). We first compute the magnitude maps input image, and then calculate differential excitation orientation each pixel over map. After that, we use these excitations orientations to construct GWLD histogram representation. Finally, intersection adopted measure similarity between different histograms. The experimental results on SEU database verify...
To obtain the satisfied performance of face recognition under complex illumination, a novel method named MD-LBP (Multi-Direction Local Binary Pattern) is proposed in this paper. Based on LBP (Local Pattern), local feature extraction method, which optimized coding scheme by considering relationship between center pixel and weighted pixels its neighborhood. Furthermore, unlike original gray scale histogram used new way to get vector not only describes holistic spatial information image, but...
Weather risk causes uncertain crop yield and price further influences the willingness of farmers to participate in contract farming honour contract. In this study, we investigate optimal decisions for between a profit‐maximizing manufacturer multiple identical under weather risk, using game‐theoretical approach. We discuss two different cases. first case, sets ensure any condition. While second lower only guarantee that will not renege certain condition but has chance purchase products from...
Herein, we report a mild, one-pot method for silver-catalyzed tandem cycloisomerization/[5 + 2] cycloaddition reactions between readily accessible cyclopropyl-tethered allenyl ketones and benzopyranone-derived oxidopyrylium ylides. The proceed via cyclobutene-fused furan intermediate generated in situ by cycloisomerization/1,2-carbene transfer/ring-expansion cascade. This method, which features an unprecedented formal [5 cycloaddition, delivers good to excellent yields of structurally...
