The overall suicide rate in China has dropped substantially since the 1990s, with patterns changing significantly. This study aims to further explore latest changes rates China. Data on gender-age-specific for rural and urban residents aged 15 years above were retrieved from official records. Joinpoint regression analyses applied analyze time trends of rates. Overall, significantly 2002 2015. However, national have decreased at a slower pace 2006. Joinpoints also observed among males,...
Piezochromic materials with pressure-dependent photoluminescence tuning properties are important in many fields, such as mechanical sensors, security papers, and storage devices. Covalent organic frameworks (COFs), an emerging class of crystalline porous (CPMs) structural dynamics tunable photophysical properties, suitable for designing piezochromic materials, but there few related studies. Herein, we report two dynamic three-dimensional COFs based on aggregation-induced emission (AIE) or...
Achieving enhanced or blue-shifted emission from piezochromic materials remains a major challenge. Covalent organic frameworks (COFs) are promising candidates for the development of owing to their dynamic structures and adjustable optical properties, where behaviors not solely determined by functional groups, but also greatly influenced specific geometric arrangement. Nevertheless, this area relatively understudied. In study, successful synthesis series bicarbazole-based COFs with varying...
It is challenging for cloud-native relational databases to meet the ever-increasing needs of scaling compute and memory resources independently elastically. The recent emergence disaggregation architecture, relying on high-speed RDMA network, offers opportunities build cost-effective elastic databases. There exist proposals let unmodified applications run transparently disaggregated systems. However, running database kernel atop such experiences notable performance degradation time-consuming...
Benefiting from unified sensors and long-term traffic engagement, for-hire vehicles (FHVs) are widely considered the mainstay for vehicular crowd sensing (VCS) tasks. However, incentivizing FHVs to participate in tasks remains a fundamental challenge FHV-enabled VCS systems: one thing, distribution diversity of orders limits participating VCS; another, FHVs' operating states determine whether they free execute To address above issues, this article proposes SHIP, State-aware Hybrid Incentive...
Many scientific and engineering applications involve finding more than one optimum. A comprehensive review of the existing works done in field multimodal function optimization was given a critical analysis methods also provided. Several techniques solving problems were introduced, such as clearing, deterministic crowding, sharing, species conserving so on. And we summarized defects algorithms: lacking self-adaptive adjustment function, requiring setting some parameters according to different...
Wood-plastic composites (WPCs) made by selective laser sintering (SLS) approach of 3D printing offer many advantages over single polymer materials, such as low cost, sustainability, and better accuracy. However, WPCs via SLS are too weak to have widespread applications. In order increase the mechanical properties WPCs, a novel type containing 0, 0.05, 0.1 0.15 wt % carbon nanotubes (CNT), 14 wood fibers, 86 polyether sulfone (PES) was manufactured SLS. The experimental results showed that...
Abstract Substantial amount of polyethylene terephthalate/cotton (PET/cotton) blend fabrics have been handled as waste especially in recent decades on account the technological barrier and/or low economic benefit recycling PET from PET/cotton fabrics. Herein, a facile and effective approach was utilized to modify with co‐deposition polyethyleneimine (PEI) catechol (CCh) improve interfacial bonding fiber‐matrix. The surface morphology composition were investigated by FESEM, ATR/FTIR, XPS....
Developing well-performing and stable bifunctional electrocatalysts is of great importance for efficient green hydrogen production through water electrolysis. Herein, a three-dimensional self-supported CoMoS3.13/FeS2/Co3S4 on carbon paper (FeCoMoS/CP) heterostructure with interconnected nanosheets overall splitting was fabricated by facile hydrothermal method followed vulcanization treatment. The FeCoMoS/CP high structural integrity more accessible active sites can effectively optimize the...
Singlet oxygen, as a kind of reactive oxygen species, plays an important role in organic synthesis and biological processes. However, these excited molecules have short life high reactivity; thus it is great challenge to capture singlet oxygen. Here, for the first time two functionalized 3D covalent frameworks (3D COFs) with polycyclic aromatic hydrocarbons, termed JUC‐575 JUC‐576, reversible release are reported. These COFs, constructed from anthracene or naphthalene derivatives, can...
Recently, the pharmaceutical industry has shifted to pursuing combination therapies that comprise more than one active ingredient. Interestingly, have been used for 2500 years in traditional Chinese medicine (TCM). Understanding optimal proportions and synergistic mechanisms of multi-component drugs are critical developing novel strategies combat complex diseases. A new multi-objective optimization algorithm based on least angle regression-partial squares was proposed construct predictive...
By providing loosely coupled, lightweight, and independent services, the microservice architecture is promising for large-scale complex service provision requirements in Internet of Things (IoT). However, it requires more fine-grained resource management orchestration provision. Most existing solutions are based on those designed traditional cloud. They can only provide coarse-grained allocation using possibly conflicting weighted objectives. In this article, we present a approach to...
The achievements of the project "highway capacity research" in "9th Five-Year" period China have supported current "Highway Engineering Technical Standard" and "The Specification Highway Design", which are most important specifications for design construction highway strongly operation tens thousands kilometers highway. At present, China's industry is still a rapid development. By end 2014, total mileages network exceeds 4,400,000 kilometers, freeway's mileage 112,000 kilometers. With this...
The plasma membranes (PM) of mammalian cells contain diverse lipids, proteins, and carbohydrates that are important for systemic recognition communication in health disease.
