The increasing availability of GPS-enabled devices is changing the way people interact with Web, and brings us a large amount GPS trajectories representing people's location histories. In this paper, based on multiple users' trajectories, we aim to mine interesting locations classical travel sequences in given geospatial region. Here, mean culturally important places, such as Tiananmen Square Beijing, frequented public areas, like shopping malls restaurants, etc. Such information can help...

The increasing availability of location-acquisition technologies (GPS, GSM networks, etc.) enables people to log the location histories with spatio-temporal data. Such real-world imply, some extent, users' interests in places, and bring us opportunities understand correlation between users locations. In this article, we move towards direction report on a personalized friend recommender for geographical information systems (GIS) Web. First, system, particular individual's visits geospatial...

Abstract The electronic structure of transition metal complexes can be modulated by replacing partial ion to obtain tuned intrinsic oxygen reduction reaction (ORR) or evolution (OER) electrocatalytic activity. However, the anion‐modulated ORR activity is still unsatisfactory, and construction hetero‐anionic remains challenging. Herein, an atomic doping strategy presented prepare CuCo 2 O 4‐x S x /NC‐2 (CCSO/NC‐2) as electrocatalysts, structrual characterization results favorably demonstrate...

The advance of location-acquisition technologies enables people to record their location histories with spatio-temporal datasets, which imply the correlation between geographical regions. This indicates relationship locations in space human behavior, and can enable many valuable services, such as sales promotion recommendation. In this paper, by taking into account a user's travel experience sequentiality have been visited, we propose an approach mine from large number users' histories. We...

Introduction: The emergence of multidrug-resistant Klebsiella pneumoniae ( K. ) and the decline effective antibiotics lead to urgent need for new antibacterial agents. aim this study is investigate therapeutic effect antimicrobial peptides against gentamicin-resistant (RT) screen peptides. Methods: In study, RT strains were induced by gradient gentamicin, selected detecting expression levels efflux pump genes, porin biofilm formation genes combined with their effects on cells. Then four...

Sepsis is a systemic inflammatory response syndrome caused by infection, with high incidence and mortality. Therefore, it necessary to carry out an effective anti-infection treatment. In this work, we designed synthesized red blood cell (RBC) membrane-coated PLGA nanoparticles named γ3-RBCNPs, which target the highly expressed intercellular adhesion molecule-1 (ICAM-1) at site of infection through γ3 peptide on its surface kill Klebsiella pneumoniae ciprofloxacin encapsulated in core....

In this study, we discuss the weak dominance relation between two binary operations which is closely related with relation. First, present some basic properties of and prove that there exists no t-norm weakly dominating a t-conorm. Then provide necessary sufficient conditions t-conorm for different cases: both are Archimedean or ordinal sums. Lastly, t-norms discussed.

We study the occurrence of stochastic resonance phenomenon in nonlinear bistable system when forcing signal is at high frequency, based on frequency shifting characteristic Fourier transform. The simulation results show that after input to a small one, and output power spectrum peaks are strongly enhanced this by adjusting parameters. ability detecting weak overwhelmed strong noise within rather broad range improved paper.

Abstract A novel Toeplitz fourth-order cumulant (FOC) orthonormal propagator rooting method (TFOC ‐ OPRM) of direction-of-arrival (DOA) estimation for uniform linear array ( ULA ) is proposed in this paper. Specifically, the modified (i.e., reduced-dimension) FOC MFOC matrix achieved at first via removing redundant information encompassed primary matrix; then, TFOC which possesses structure can be recovered by utilizing approximation method. To reduce computational complexity, an effective...

In this paper, we design an active four-wheel steering optimal controller with linear quadratic regulator (LQR), and optimize it using improved particle swarm algorithm (PSO) for the difficult problem of taking parameters control state weight matrix in LRQ. Compared ideal expected value, stability PSO-LQR system vehicle different operating conditions is improved, tracking accuracy sideslip angle yaw rate improved.

This paper found that the crystalline volume ratio (Xc) of μc-Si deposited on SiNx substrate is higher than 7059 glass. At same silane concentration (SC) (for example, at SC=2%), Xc more 64%, but just 44% if Conning 7059. It considered `hills' would promote growth thin film, which has been confirmed by atomic force microscope (AFM) observation. Comparing several film transistor (TFT) samples whose active-layer were under various SC, this appropriate SC for used in TFT as active layer should...
