Purpose With the increasing number of mobile applications, efficiently recommending applications to users has become a challenging problem. Although existing application recommendation approaches based on user attributes and behaviors have achieved notable effectiveness, they overlook diffusion patterns interdependencies topic-specific among groups. This paper aims capture To achieve this, topic-aware neural network-based method, referred as TN-MR, is proposed. Design/methodology/approach In...

ABSTRACT Background Rising antimicrobial resistance has significantly challenged the eradication rates of Helicobacter pylori . Due to its invasive nature, susceptibility testing based on endoscopic biopsy is controversial, while few studies have focused efficacy tailored bismuth quadruple therapies (BQT) fecal as a first‐line treatment. Methods In this multicenter study, 598 H. ‐positive patients without previous treatment were recruited and randomly assigned three groups: empirical BQT,...

A multitransmitter multireceiver WPT proposed this article for application of submerged buoy, and numbers beacons can be charged at same time to send more data. Both series parallel connection structures several coils are analyzed detail. In order increase efficiency ultracapacitors charging process, a maximum tracking with primary current controller an optimal resistance studied designed. All mentioned...

The number of online services is rapidly increasing due to the increased adoption services-oriented technology. In this context, recommendation systems can provide high-quality Web that meet Mashup developers' expectations. use different kinds auxiliary information in commonplace. They enrich so they make relevant recommendations. Yet, knowledge graph-based service usually only considers textual semantic and ignores importance discrete attribute for recommendation. This may lead inability...

Purpose With the introduction of graph structure learning into service classification, more accurate structures can significantly improve precision classification. However, existing methods tend to rely on a single information source when attempting eliminate noise in original and lack consideration for generation mechanism. To address this problem, paper aims propose estimation neural network-based classification (GSESC) model. Design/methodology/approach First, method uses local smoothing...

This paper proposes a wireless power transfer (WPT) system with quasi-uniform magnetic coupling to satisfy the Unmanned Aerial Vehicle (UAV) lightweight constant current (CC) charging without secondary feedback control. The traditional wired for UAVs is less automated and not portable. WPT as new way of energy supply has shown great potential safety automation. However, some actual challenges still exist due UAV's special structure requirements. Accordingly, coupler receiving coil double...

Inductively coupled power transfer (ICPT) is a new technology used in the mooring buoy for underwater sensors' supply. In this article, an ICPT system with cable to double ultracapacitor chargers proposed. First, model analyzed detail, including primary side of abovewater system, cable, and secondary system. Second, reduce torque between noncontact rotary magnetic coupler, which can provide two degrees freedom, designed. Third, considering that charging voltage difficult feedback directly,...

Batteries are commonly used as the power source of present underwater sensors ocean buoys. However, batteries need to be frequently replaced, which is costly. To implement real-time supply for a buoy’s sensor, new inductively coupled transfer (ICPT) system that consists two couplers and closed cable proposed in this paper. The special cable, both mooring transmission media, designed diminish influence changes on impedance. A model particular ICPT established. Optimization parameters carried...

Inductively coupled power transfer (ICPT) systems, which are superior to batteries due their real-time supplycapacity have been used in mooring buoys for the purpose of long-term measurements. A multiple-receiver ICPT system buoys, contains a cable transmitting power, is proposed this paper obtain corresponding profile parameters. Series compensation applied all three sections, including transmitter, and multiple receivers. The voltage an underwater with arbitrary load can be stabilized. On...

Purpose With the continuous increase in Web services, efficient identification of services that meet developers’ needs and understanding their relationships remains a challenge. Previous research has improved recommendation effectiveness by using correlations between through graph neural networks (GNNs), while it not fully leveraged service descriptions, limiting depth diversity learning. To this end, method called LLMSARec, based on Large Language Model semantic alignment, is proposed. This...

Accurate measurement of sound speed is important to calibrate a velocity profiler which provides real-time the sonar equipment in oceanographic survey.
