A graph $G$ is $k$-vertex-critical if $\chi(G) = k$ but $\chi(G-v)<k$ for all $v \in V(G)$. $(H_1,H_2)$-free it contains no induced subgraph isomorphic to $H_1$ nor $H_2$. $W_4$ the consisting of a $C_4$ plus an additional vertex adjacent vertices $C_4$. We show that there are finitely many $(P_5,W_4)$-free graphs $k \ge 1$ and we characterize $5$-vertex-critical graphs. Our results imply existence polynomial-time certifying algorithm decide $k$-colorability each where certificate either...

This paper deals with the description of a telerobotic surgery experiment, conducted on July 7, 1993, between Politecnico di Milano, Telerobotics Laboratory, Italy, and Jet Propulsion Pasadena, CA. It describes results obtained, new objectives proposed technical equipment. also provides comparison different solutions adopted. Telerobotic requires particular skill; integration human capabilities robotics in offers useful for robotic applications fields, especially health care.

Surgical resection of medulloblastoma (MB) remains a challenge. At present, variety tracers have been used for intraoperative tumor visualization. However, there are few reports on the visualization MB. Hence, we reported our experience applying fluorescein sodium (FS) in MB surgery.We retrospectively analyzed clinical information patients with confirmed by surgery and pathology from January 2016 to December 2020 Sun Yat-sen University Cancer Center. A total 62 were enrolled, which 27...

Abstract Afterglow brightness represents one of the most important characteristics in application afterglow materials. High molar absorption coefficient, high efficiency, and long lifetimes are required to achieve intense afterglow. However, current strategies cannot simultaneously fulfill these requirements due specific intrinsic problems. Here, based on understanding difluoroboron β ‐diketonate systems, manipulation higher triplet excited states is conceived selectively enhance intersystem...

Blue afterglow emitters contribute one of the three primary colors and can be used to generate other via energy transfer. Statistics shows that although there are examples blue with high efficiency long lifetime, such require ultraviolet-B excitation switch on their properties. Here, we fabricate visible-light-excitable sky-blue thermally activated delayed fluorescent (TADF)-type organic materials a dopant-matrix strategy, where TADF represents fluorescence. Luminescent difluoroboron...

This article describes the significance in human, scientific, and technical terms of first experiment telerobotic surgery carried out between NASA Jet Propulsion Laboratory Pasadena, California, Telerobotics Politecnico di Milano on 7 July 1993. An Italian robot was remotely controlled by an surgeon United States. The robot's task to perform a surgical operation model containing pig's organs, involving execution biopsy, aspi ration organic material, two incisions preparation laparoscopy....

Polyamide (PA) nanofiltration (NF) membranes suffer from biofouling, which will deteriorate their separation performance. In this study, we proposed a strategy to incorporate silver nanoparticles (Ag NPs) into PA NF in situ, order simultaneously enhance water permeability and antibacterial The chloride-doped carbon quantum dots (Cl-CQDs) with photocatalytic performance were pre-embedded the selective layer. Under visible light irradiation, photogenerated charge carriers generated by Cl-CQDs...

CDK4/6 plays a crucial role in various cancers and is an effective anticancer drug target. However, the gap between clinical requirements approved drugs unresolved. Thus, there urgent need to develop selective oral inhibitors, particularly for monotherapy. Here, we studied interaction abemaciclib human CDK6 using molecular dynamics simulations, binding free energy calculations, decomposition. V101 H100 formed stable hydrogen bonds with amine-pyrimidine group, K43 interacted imidazole ring...

To adapt game difficulty upon character's strength, Dynamic Difficulty Adjustment (DDA) and some other learning strategies have been applied in commercial designs. However, most of the existing approaches could not ensure diversity results, rarely attempted to coordinate content generation behaviour control together. This paper suggests a solution that is based on multi-level swarm model ecosystem mechanism, order provide more flexible way balance control.

So far, most of the proton exchange membrane fuel cell (PEMFC) models are difficult to apply in control system design. In this paper, a dynamic model PEMFC is set up. Based on model, self-adaptive fuzzy PID controller and respectively used output voltage. The simulation results show that, adaptive can characteristics more effectively than controller, which ensure operate stably.
