The multidisciplinary team (MDT) approach is increasingly being utilized in the management of complex head and neck diseases. This study analyzed the benefits of MDT for patients with head and neck diseases as primary or secondary conditions and categorized MDT meetings into two types: head and neck surgery initiation (HNI) and head and neck surgery participation (HNP). The study further explored the characteristics of these MDT meetings and the factors influencing patient compliance, aiming to optimize MDT treatment models to maximize patient benefits.
Based on the NS Model, a mixed traffic flow on single lane is simulated in the paper, which includes two-classification vehicles owing the different max-velocity. How the traffic flow is changed for different density and different discrete degree is researched and the influence of the density of traffic flow and the discrete of following-velocity on the chaos of traffic flow is analyzed in different values named approximate entropy and statistical complexity, which are changed as the variable value.
Absorption-dominated electromagnetic interference (EMI) shielding materials are more attractive to manage the increasing electromagnetic radiation pollution than conventional reflection-dominated counterparts due to their advantages of balancing the efficient EMI shielding performance while minimizing the secondary pollution of the reflected electromagnetic (EM) wave. Herein, we first fabricate ferroferric oxide/carbon nanotubes/waterborne polyurethane (Fe3O4/CNTs/WPU) aerogels and then coat Ti3C2Tx MXene at the bottom to construct an asymmetric structure. Moreover, the medium or transition layer is formed during the coating process of MXene-ferroferric oxide by the gravity and aerogel's capillary action. This delicate design makes them with obvious absorption, transition, and reflection layers according to the progressive modular design principle. The composite aerogels show an average EMI shielding effectiveness (SE) of 20.06 dB, low reflectivity of 0.396, and specific EMI SE of SSE/t of 332.60 dB cm2 g–1 in the X-band when the MXene content is only 2.35 vol %. Additionally, the resultant aerogels exhibit remarkable flexible and mechanical properties, which could even bear weights of about 4500 times their own weight. In sum, this work provides a promising absorption-dominated EMI shielding candidate with flexible and high strength features.
The development of absorption-dominated electromagnetic interference shielding materials holds significant research potential, yet achieving an efficient electromagnetic shielding absorption capacity through simplified and convenient procedures remains a considerable challenge. Herein, a porous composite material prepared by poly(ethylene glycol) diacrylate (PEGDA) and pentaerythritol tetrakis(3-mercapto-propionate) (PETMP) by click chemistry is proposed, following with the loading of Ti3C2Tx MXene nanosheet/cellulose nanofiber (MXene/CNF) onto the surface of the composite materials by coating. In this study, the influence of sample thickness on the absorption and reflection properties is discussed. The hypothesis deductive method proves that the sample can be analyzed according to multiple transmission line models. Benefitting from the excellent electrical conductivity of MXene/CNF with the absorptive ability of PEG porous polymers and the Salisbury screen effect, this composite material achieves an ultrahigh electromagnetic shielding effectiveness (EMI SE) of 60 dB and an absorption coefficient (A) of 92% at 34 dB with the use of less than 0.3 wt % of conductive filler, which shows a prosperous application prospect in electromagnetic interference shielding field.
Ramp metering is one of the most important parts of freeway traffic control. In this paper, a prediction method based on a nonlinear model is adopted to avoid rapid congestion and big-scale spreading and to predicatively control neighboring ramp traffic volume at congested road sections. Simulated results show that this method has maintained stable vehicle flow of the main line. It not only effectively avoids spreading of traffic congestion, but also maintains a smooth ramp regulation rate.
Metal halide perovskites (MHPs) have been widely investigated for various photocatalytic applications. However, the dual-functional reaction system integrated selective organic oxidation with H2 production over MHPs is rarely reported. Here, we demonstrate for the first time the selective oxidation of aromatic alcohols to aldehydes integrated with hydrogen (H2) evolution over Pt-decorated CsPbBr3. Especially, the functionalization of CsPbBr3 with graphene oxide (GO) further improves the photoactivity of the perovskite catalyst. The optimal amount of CsPbBr3/GO-Pt exhibits an H2 evolution rate of 1,060 μmol g-1 h-1 along with high selectivity (>99%) for benzyl aldehyde generation (1,050 μmol g-1 h-1) under visible light (λ > 400 nm), which is about five times higher than the CsPbBr3-Pt sample. The enhanced activity has been ascribed to two effects induced by the introduction of GO: 1) GO displays a structure-directing role, decreasing the particle size of CsPbBr3 and 2) GO and Pt act as electron reservoirs, extracting the photogenerated electrons and prohibiting the recombination of the electron-hole pairs. This study opens new avenues to utilize metal halide perovskites as dual-functional photocatalysts to perform selective organic transformations and solar fuel production.
