High quality In2S3 kinks were synthesized via a kinetically controlled thermal deposition process and their optoelectronic characteristics were systematically explored. The growth mechanism was attributed to the combination of kinetic dynamic, crystal fadal energy, and surface roughness. Two trap induced emission bands were evidenced via a low temperature cathodoluminescence （CL） study. Furthermore, the nanowire junctions demonstrated a degenerative photodetection performance, as compared to the straight arms, attributed to a stress-induced extra series resistance measured from the kinked area. The well-controllable shape of the inorganic nanostructures and the detailed exploration of their optoelectronic properties are particularly valuable for their further practical applications.

Cyber physical systems(CPSs) incorporate computation, communication, and physical processes. The deep coupling and continuous interaction between such processes lead to a significant increase in complexity in the design and implementation of CPSs. Consequently, whereas developing CPSs from scratch is inefficient, developing them with the aid of CPS run-time supporting platforms can be efficient. In recent years, much research has been actively conducted on CPS run-time supporting platforms. However, few surveys have been conducted on these platforms. In this paper, we analyze and evaluate existing CPS run-time supporting platforms by first classifying them into three categories from the viewpoint of software architecture: component-based platforms, service-based platforms, and agent-based platforms. Then, for each type, we detail its design philosophy, key technical problems, and corresponding solutions with specific use cases. Subsequently, we compare existing platforms from two aspects: construction approaches for CPS tasks and support for non-functional properties. Finally, we outline several important future research issues.

Approximately 70% of newly diagnosed bladder tumors are non-muscle invasive bladder cancer （NMIBC）. NMIBC accounts for approximately 80% of total bladder cancer cases. Bacillus Calmette-Guerin （BCG） instillation and maintenance is considered as the standard adjuvant treatment for superficial bladder cancer. A number of randomized studies have focused on the benefit of maintenance therapy following initial BCG induction. To provide further insights into the effect of intravesical instillation on recurrence in patients with NMIBC, we analyzed this relationship by conducting an updated detailed meta-analysis. Evidence suggested that adjuvant intravesical BCG with maintenance treatment is significantly effective for the prophylaxis of tumor recurrence in patients with NMIBC.
