In many complex systems, devices are typically monitored and generating massive multivariate time series. However, due to the patterns little useful labeled data, it is a great challenge detect anomalies from these series data. Existing methods either rely on less regularizations, or require large number of leading poor accuracy in anomaly detection. To overcome those limitations, this paper, we propose an unsupervised detection framework, called DAEMON (Adversarial Autoencoder Anomaly...
With the fast-paced development of mobile networks and widespread usage devices, Spatial Crowdsourcing (SC), which refers to assigning location-based tasks moving workers, has drawn increasing attention in recent years. One critical issues SC is task assignment that allocates appropriate workers. In this paper, we propose a novel problem, namely Coalition-based Task Assignment (CTA), where spatial (e.g., house removals, furniture installation) may require more than one workers (forming...
Crowdsourcing aims to enable the assignment of available resources completion tasks at scale. The continued digitization societal processes translates into increased opportunities for crowdsourcing. For example, crowdsourcing enables computational humans, called workers, that are notoriously hard computers. In settings faced with malicious actors, detection such actors holds potential increase robustness platform. We propose a framework Outlier Detection Streaming Task Assignment improve by...
Background As climate change intensifies, ambient temperatures have become a global concern, leading to an increasing number of studies examining the impact temperature on human health. Extreme weather events, including heatwaves and cold spells, are becoming more frequent severe. Numerous highlighted positive correlation between non-optimal mortality. Understanding these impacts is crucial for developing targeted public health interventions accurately predicting future burden associated...
Least-squares migration (LSM) aims to seek the best-fit solution for subsurface reflectivity with high image resolution and balanced amplitudes by minimizing mismatching between synthetic observed seismic data. It can be implemented either in data domain or domain. Data-domain LSM iteratively updates using gradient-based algorithms. However, it requires expensive computation cost converge a good solution, which is still challenging large-scale datasets under current computational capacity....
Juvenile hormone binding protein (JHBP) is a key regulator of JH signaling, and crosstalk between 20-hydroxyecdysone (20E) can activate fine-tune the mitogen-activated kinase cascade, leading to resistance insecticidal proteins from Bacillis thuringiensis (Bt). However, involvement JHBP in Bt Cry1Ac Plutella xylostella remains unclear. Here, we cloned full-length cDNA encoding JHBP, quantitative real-time PCR (qPCR) analysis showed that expression PxJHBP gene midgut Cry1Ac-susceptible strain...
The pervasiveness of GPS-enabled devices and wireless communication technologies flourish the market Spatial Crowdsourcing (SC), which consists location-based tasks requires workers to physically be at specific locations complete them. In this work, we study problem Worker Churn based Task Assignment in SC, where are assigned by considering workers' churn. particular, aim achieve highest total rewards task assignments on worker churn prediction. To solve problem, propose a two-phase...
Recent years have witnessed a revolution in Spatial Crowdsourcing (SC), which people with mobile connectivity can perform spatio-temporal tasks that involve travel to specified locations. In this paper, we identify and study depth new multi-center-based task allocation problem the context of SC, where multiple centers exist. particular, aim maximize total number allocated while minimizing average difference. To solve problem, propose two-phase framework, called Task Allocation Geographic...

However, due to the patterns little useful labeled data, it is a great challenge detect anomalies from these series data. Existing methods either rely on less regularizations, or require large number of leading poor accuracy in anomaly detection. To overcome limitations, this paper, we propose an adversarial autoencoder detection interpretation framework named DAEMON, which performs...
Microplastics and antibiotics are two common pollutants in the ocean. However, due to changes of salinity temperature ocean, their interaction significantly different from that fresh water, mechanism remains unclear. Here, interactions sulfamethoxazole (SMZ) microplastics were studied at temperatures salinities. The saturation adsorption capacity SMZ polypropylene (PP), polyethylene (PE), styrene (PS), polyvinyl chloride (PVC), synthetic resins (ABS) highest 20 °C, with 0.118 ± 0.002 mg·g−1,...
The calculation of conformal mapping for irregular domains is a crucial step in deriving analytical and semi-analytical solutions irregularly shaped tunnels rock masses using complex theory. optimization methods, iteration the extended Melentiev’s method have been developed adopted to calculate function tunnel engineering. According strict definition theorems mapping, it proven that these three methods only map boundaries do not guarantee mapping’s properties due inherent limitations....
An environment-friendly and effecient method for simultaneous determination of five alkaloids (nunciferine, O-nornuciferin, liriodenine, armepavine pronuciferine) in rat plasma was established by HPLC-MS/MS associated with micro solid phase extraction (micro-SPE).

With the explosion of GPS-enabled smartphones and social media platforms, geo-social networks are increasing as tools for businesses to promote their products or services. Influence maximization, which aims maximize expected spread influence in networks, has drawn attention. However, most recent work tries study maximization by only considering geographic distance, while ignoring users' spatio-temporal behavior on information propagation location promotion, can often lead poor results. To...
With the widespread diffusion of smartphones, Spatial Crowdsourcing (SC), which aims to assign spatial tasks mobile workers, has drawn increasing attention in both academia and industry. One major issues is how best workers. Given a worker task, will choose accept task based on her affinity towards can propagate information attract more workers perform it. These factors be measured as worker-task influence. Since workers' affinities are different issuers may ask who performed them, it...
The small strain theory underestimates the self-bearing capacity of rock masses, especially for a soft tunnel under high geostress. To perform an efficient and accurate calculation provide reference stiffness design tunnel, finite solution circular in Mohr–Coulomb strain-softening masses with non-associated flow rule was derived as three sets differential equations Lagrangian coordinate, which are residue region, softening elastic respectively. Based on bisection method, iteration procedure...
