Scintillating materials, which can convert high energy X-ray radiation into visible luminescence [1], are crucial parts of Xray imaging technology. Since the discovery of X-ray in 1895, scintillating materials have witnessed wild applications in various fields, including security inspection, space exploration, nondestructive detection, and medical diagnostics [2,3]- Conventional scintillators are generally large inorganic crystals and can only be grown at high temperature, which significantly increases the manufacturing difficulty and cost. The luminescence of current crystal scintillators is usually limited by lowefficiency or afterglow effects, and is difficult to be tuned cross the visible spectrum. As traditional scintillators have reached their performance limits, exploration of new scintillators has become a crucial topic considering the increased demands of X-ray imaging and detection technology [4-6].

Autogenous self-healing is the innate and fundamental repair capability of cement-based materials for healing cracks.Many researchers have investigated factors that influence autogenous healing.However,systematic research on the autogenous healing mechanism of cement-based materials is lacking.The healing process mainly involves a chemical process,including further hydration of unhydrated cement and carbonation of calcium oxide and calcium hydroxide.Hence,the autogenous healing process is influenced by the material constituents of the cement composite and the ambient environment.In this study,different factors influencing the healing process of cement-based materials were investigated.Scanning electron microscopy and optical microscopy were used to examine the autogenous healing mechanism,and the maximum healing capacity was assessed.Furthermore,detailed theoretical analysis and quantitative detection of autogenous healing were conducted.This study provides a valuable reference for developing an improved healing technique for cement-based composites.

Despite advances in diagnostic and therapeutic technologies for cardiovascular diseases(CVDs),it remains a leading cause of mortality and morbidity worldwide.This underscores the urgency for innovative approaches aiming at early and precise detection and treatment of CVDs to reduce the disease burden.Iron oxide nanoparticles(IONPs),with their unique magnetism and bioproperties,have shown great potential in this regard.In this review,we will begin with a brief overview of the synthesis and properties of IONPs.We will then focus on the latest applications of IONPs in CVDs,including diagnosis and treatment.The use of IONPs in the integration of diagnosis and treatment for CVDs is a promising field,and will be addressed in a separate section.The translational potential and challenges of IONPs will also be discussed.In conclusion,ongoing research and development of IONP-based strategies are highly likely to address current challenges effectively,and offer more personalized and efficient options for the diagnosis and treatment of CVDs.

A novel graphene oxide (GO) modified polyurethane thermal conductive insulating adhesive with small addition and excellent insulation properties was prepared by in-situ polymerization using GO as thermal conductive filler.The effects of GO content on the mechanical performance,thermal conductivity,thermal stability and insulation properties of the modified polyurethane adhesive were studied.The results showed that the tensile strength and elongation at break of polyurethane adhesive increased at first and then decreased with the increase of GO content.The thermal conductivity and thermal decomposition temperature of GO/PU composite adhesive can be effectively improved by adding appropriate amount of GO.The tensile strength,thermal conductivity and thermal decomposition temperature of polyurethane adhesive reached the maximum when GO content was 1.5 wt%.The novel GO-modified polyurethane adhesive exhibited good insulation property.The development of GO/PU thermal conductive adhesive will provide a facile method for effectively solving the “trade-off” problem between low filling and high thermal conductivity.

China has started shifting from relying on supply management to demand management strategy in addressing its water shortage problems.Water option,a financial derivative for water commodity,has been utilized to manage water demands in the United States and Europe since the 1990 s but is still novel to China.In this study we analyzed the pros and cons of China’s existing system for water rights transfers and proposed an alternative,flexible trading instrument-water options for China.Incorporating the uncertainty to water option pricing,this study first conducted an empirical analysis of the water option in the water-receiving area of the Hanjiang-Weihe River Transfer Project of China,and then evaluated the benefits of the water option applications.Results show that water option trading can bring water cost saving and increase the potential industrially added value for industrial enterprises in the receiving area,and trading of short-and-medium term water options is more favorable than the long-term water options trading.The novel water option trading proposed in this study,once verified through pilot studies,will be helpful in addressing water shortage problems in China.

Discrete Level of Detail (LOD) strategy is an effective solution for balancing the inherentcontradiction between quality and speed in computer graphics. However, application ofthis strategy requires both the appropriate selection approach and the visually comfortable transition procedure to reduce the popping effects introduced by switching betweendifferent levels. In this paper, a novel automatic LOD selection method based on viewpoint entropy was proposed. Firstly, the traditional calculation method of viewpointentropy contained in a scene was improved for the preprocessing of LOD models. Then,the runtime rendering scheme combined with our selection method was designed forbalance of frame rate during real-time rendering, and a novel smoothing LOD transitionstrategy based on Alternate Frame Rendered (ALR) was put forward for eliminationof popping effects. Finally, an example of complex scene combined with our proposalwas researched to verify its real-time performance and ability in holding continuity ofrendered images. Experimental studies show the effectiveness for stabilizing frame rateand improvements in reducing loss of continuity.
