Artificial nanocluster crystals of In, Ga, and Al were fabricated using a technique in which surface mediated magic clustering is used to achieve identical cluster size while the Si(111)-7\ifmmode\times\else\texttimes\fi{}7 as template for ordering clusters. The atomic structures, formation mechanism stability nanoclusters studied with situ scanning tunneling microscopy combined first-principles total energy calculations. Our study shows that delicate control growth kinetics extremely...

During pulse signal collection, width information of waves is essential for the diagnosis disease. However, currently used measuring instruments can only detect amplitude while can't acquire information. This paper proposed a novel wrist acquisition system, which could realize simultaneous measurements and dynamic under different static forces. A tailor-packaged micro-electro-mechanical system (MEMS) sensor array was employed to collect signals, conditioning circuit designed process...

Abstract Oil and gas resources serve as the driving force for economic social development. This rapid development of science technology has accelerated exploration, development, utilization oil resources, thus led to spurts in related research. However, research trends global exploration vary with progress well demands. Accordingly, they are not easily captured. study explores through bibliometric analysis 3460 articles on collected from Web Science database published 2013 2023. The...

Control over molecular topologies and/or heteroatom doping of polycyclic aromatic hydrocarbons (PAHs) may alter their electronic structures and achieve desirable physical properties. Herein, this work challenges boron‐doping edge‐transformation π‐extended PAHs. We successfully synthesized a series large‐size PAHs featuring boron‐doped zigzag/armchair edge topology through one‐pot multifold Scholl cyclization reaction. Two them possess the desired C3‐symmetric unexpected unsymmetrical C54B3...

Fertilizer practices can significantly impact the fruit quality and microbial diversity of orchards. The fungi on surface fruits are essential for storability safety. However, it is not clear whether fertilization affects fungal community structure grape berries. Here, grapes harvested from three fertilizer treatments were analyzed shortly after picking (T0) following 8 days storage (T1). study involved treatments: (1) common chemical 2 years (CH); (2) increased organic reduced 1 year (A.O);...

Viviparidae are widely distributed around the globe, but there considerable gaps in taxonomic record. To date, 18 species of viviparid genus Cipangopaludina have been recorded China, is substantial disagreement on validity this taxonomy. In study, we described shell and internal traits these to better discuss related species. We found that C. ampulliformis synonym lecythis, wingatei chinensis,while ampullacea fluminalis subspecies lecythis chinensis, respectively. dianchiensis should be...

Comprehensive rice field planting and aquaculture systems stand as the quintessential model of ecological recycling agriculture in China, with a rich historical legacy [1,2].In recent years, propelled by influence national policy directives, market dynamics, rapid development integrated farming technologies, comprehensive have experienced swift dissemination application.This approach not only effectively mitigates existing conflicts between agricultural lands but also provides pragmatic solutions

Secondary forests have become the major forest type worldwide. Research on spatial patterns and associations of tree species at different developmental stages may be informative in understanding structure dynamic processes secondary forests.In this study, we used point pattern analysis to analyze seedling, sapling adult a 4ha plot montane temperate northeastern China.We found that showed similar stages, aggregation was dominant pattern. The were mainly affected by habitat heterogeneity. In...

Perfectly ordered arrays of identical Al and Ga clusters nanometre size spacing were spontaneously obtained using a novel technique, in which surface-mediated magic clustering is used to achieve the cluster while Si(111)-7 × 7 surface as template for positioning order. The atomic structures, formation mechanism stability nanoclusters studied with situ scanning tunnelling microscopy combined first-principles total energy calculations. very high these nanocluster provides unprecedented...

Abstract. The veracity of urban climate simulation models should be systematically evaluated to demonstrate the trustworthiness these against possible model uncertainties. However, existing studies paid insufficient attention evaluation; most only provided some simple comparison lines between modelled variables and their corresponding observed ones on temporal dimension. Challenges remain since such comparisons cannot concretely prove that behaviours is reliable. Studies without systematic...

We present a sustainable multimodal transit system that integrates taxi-sharing with subways to alleviate traffic congestion and restore the cooperative relationship between taxis subways. This study proposes two-phase matching model based on optimization theory, in which pick-up/drop-off sequences for participants, as well their motivation shift TSS service, were considered. For transportation system, achieving reduction vehicle miles is considered be objective. tested using empirical taxi...

In LEO mobile satellite network, the L/S frequency availability is an essential task for global communication but entails several major technical challenges: high sampling rate required wideband sensing, limited power and computing resources processing load, frequency-selective wireless fading. This paper investigates issue of in system, a novel spectrum compressed signal detection approach proposed to obtain active primary users (PUs) subbands their locations that should be avoided during...

Abstract A K-theoretic classification is given of the simple inductive limits finite direct sums type I C *-algebras known as splitting interval algebras with di- mension drops. (These are subhomogeneous *-algebras, each having spectrum a union points and an open interval, torsion K 1 -group.)

In this paper, the uniform stability in one part of variables for probabilistic Boolean networks is discussed. Firstly, definition partial introduced. Using semi-tensor product, network converted to its algebraic form. From form network, necessary conditions are obtained from structure matrix and condition based on reachability network. Hence straightforward verifiable. At last, a numerical example provided demonstrate corresponding results.

Abstract In this paper, we construct a modified Green’s function with respect to the stationary Schrödinger operator on cones. As applications, not only obtain boundary behaviors of generalized harmonic functions but also characterize geometrical properties exceptional sets operator.
