Salt freeze damage is a significant factor impacting the durability of hydraulic concrete buildings in cold, saline soil areas. To settle problem salt freezing environment cold regions, specimens with different levels polypropylene fiber dosing under two conditions freeze–thaw cycles and freeze–thaw–sulfate erosion were prepared based on water diversion projects regions China. The indoor accelerated deterioration test was designed, relative dynamic elastic modulus(RDEM) mass loss rate, which...

The classification of benign and malignant lung nodules has great significance for the early detection cancer, since diagnosis can greatly increase patient survival. In this paper, we propose a novel method based on hybrid features from computed tomography (CT) images. fused 3D deep dual path network (DPN) features, local binary pattern (LBP)-based texture histogram oriented gradients (HOG)-based shape to characterize nodules. DPN is convolutional neural which integrates advantages...

The ultra-high performance of ultra-high-performance concrete (UHPC) has led to a significant increase in cement mixing, resulting an CO2 emissions. Using mineral admixtures replace partially is effective way reduce the amount. In this study, investigate effect ultrafine fly ash (UFA) and powder (UMP) on UHPC, series experiments involving single admixture use UFA, UMP, their compound mixing were conducted. Results show that dosage UHPC can be reduced 800 kg/m3 by UFA UMP. Compared with...

OVERVIEW:China has become one of the most desired locations in which to do R&D. However, it little innovation its own, and intellectual property protection is weak. This raises questions: Is China R&D more hype than reality? Do cost advantages really outweigh risk losing technology Chinese competitors? Lessons learned from managing show that order avoid typical pitfalls a developing country, any China-based must be part an overall strategy also global effort.

In order to promote the sustainable development of a social economy and ecology, social–economic–natural compound ecosystem (SENCE) conceptual framework was used construct water environmental carrying capacity index system. Taking Gansu section Yellow River basin as an example, 18 indexes were selected from 3 subsystems social, economic, natural ecology. Based on unascertained measure theory obstacle factor model, comprehensive level in 2015 2020 empirically evaluated, obstacles that...

Freeze-thaw harm is the major factor that reduces durability of hydraulic concrete buildings at high altitudes and in cold regions. To solve problem alpine regions, study prepared sixteen groups specimens with different replacement ratios iron ore tailings recycled aggregate were prepared, indoor deterioration accelerated tests designed. Nuclear magnetic resonance (NMR) technology was used to analyze pore distribution structure, macro indicators mass loss rate relative dynamic elastic...

We participated in the WMT 2018 shared news translation task on English↔Chinese language pair. Our systems are based attentional sequence-to-sequence models with some form of recursion and self-attention. Some data augmentation methods also introduced to improve performance. The best result is obtained ensemble reranking techniques. Chinese→English system achieved highest cased BLEU score among all 16 submitted systems, our English→Chinese ranked third out 18 systems.

Natural loess slopes are characterized by a strong geological structure, which is an important factor in maintaining slope stability. The magnitude and duration of the earthquake may disturb soil structure at different levels degrees, locally changing arrangement between particles. process rainfall humidification weakens cementation particles, disturbance change structural state soil, turn causes sliding along with decay mechanical properties. As instability often result series...

We present the LIMSI submission to Multilingual Word Sense Disambiguation and Entity Linking task of SemEval-2015.The system exploits parallelism multilingual test data uses translations as source indirect supervision for sense selection.The gets best results in English all domains shows that alignment information can successfully guide disambiguation.This simple but effective method serve generate high quality annotated WSD training.

To depict the effect of low-visibility foggy weather upon traffic flow on a highway with slopes, this paper proposes an extended car-following model taking into consideration drivers’ misjudgment following distance and their active reduction velocity. By linear stability analysis, neutral curves are obtained. It is shown that under all three road conditions: uphill, flat downhill, will change stable regions, while having little sizes regions. Correspondingly, velocity increase stability. The...

Abstract Background Non-suicidal self-injury (NSSI) has exhibited an increasing trend in recent years and is now globally recognized as a major public health problem among adolescents young adults. Negative life events (NLEs) are positively associated with NSSI. We sought to explore (1) whether sex plays role the risk of NLEs leading NSSI (2) played by mental (MH). Methods adopted multi-stage cluster sampling method select college students across four grades from May June 2022. Generalized...

Cascade hydropower stations are effective in water resource utilization, regional allocation, and flood risk management. Under changing climate conditions, resources would experience complex temporal spatial changes, which may lead to various issues relating control management, challenge the existing optimal scheduling of cascade stations. It is thus important conduct a study on station under conditions. In this study, Jinsha River rainfall–discharge statistical model developed based...

A neighboring lane’s vehicles are potentially important influence factors of traffic safety. In fog weather, drivers will automatically imitate the behaviors demonstrated by other in lane. To illustrate effect imitation phenomenon on safety, this paper develops an extended two-lane car-following model weather. Numerical simulations carried out to study multiple-vehicle collision induced a sudden stop, as well perturbation propagation when small is added uniform flow. The results indicate...
