Background: We evaluated UK nurses' preferences for pediatric hexavalent vaccine attributes.

Research Design And Methods: In a discrete-choice experiment study, 150 nurses chose between 2 hypothetical pediatric hexavalent vaccines with varying attribute levels (device type, plastic in packaging, time on the market, and time the vaccine can stay safely at room temperature) in a series of choice questions. Using random-parameters logit-model estimates, conditional relative attribute importance (CRAI) and odds ratios (ORs) were calculated.

The Role of Light Irradiation and Dendrimer Generation in Directing Electrostatic Self-Assembly.

pH-responsive polyamidoamine (PAMAM) dendrimers are used as well-defined building blocks to design light-switchable nano-assemblies in solution. The complex interplay between the photoresponsive di-anionic azo dye Acid Yellow 38 (AY38) and the cationic PAMAM dendrimers of different generations is presented in this study. Electrostatic self-assembly involving secondary dipole-dipole interactions provides well-defined assemblies within a broad size range (10 nm-1 μm) with various shapes.

Organic photodiodes (OPDs) are a significant focus for the next-generation of light-detection technologies. However, organic semiconductors in OPDs still face key challenges, such as low carrier mobilities and limited efficiency in generating photon-induced signals, which affect the detectable resolution and dynamic range. In this study, the characterization of the interaction between organic polymeric bulk heterojunctions and two-dimensional (2D) transition metal dichalcogenides (MoS) reveals an enhancement in photocurrent due to improved photogeneration dynamics (e.

In simulations of groundwater flow through dipping aquifers, layers of model cells are often "deformed" to follow the top and bottom elevations of the aquifers. When this approach is used in MODFLOW, adjacent cells within the same model layer are vertically offset from one another, and the standard conductance-based (two-point) formulation for flow between cells does not rigorously account for these offsets. The XT3D multi-point flow formulation in MODFLOW 6 is designed to account for geometric irregularities in the grid, including vertical offsets, and to provide accurate results for both isotropic and anisotropic groundwater flow.

Molecular dynamics simulations are performed to investigate the influence of isotope substitutions on the Eley-Rideal recombination dynamics of hydrogen isotopes from the (100) and (110) surfaces of tungsten. Dissipation of electrons and phonons is taken into account by, respectively, the local density friction approximation and the general Langevin oscillator, effective models which have been intensively used in recent years. As the coupling to surface phonons and electrons might be altered by the mass combination, the main objective of the paper is to assess the role of dissipation to the surface in the course of abstraction.
