The implementation of graphene in semiconducting technology requires precise knowledge about the graphene-semiconductor interface. In our work the structure and electronic properties of the graphene/n-Ge(110) interface are investigated on the local (nm) and macro (from μm to mm) scales via a combination of different microscopic and spectroscopic surface science techniques accompanied by density functional theory calculations. The electronic structure of freestanding graphene remains almost completely intact in this system, with only a moderate n-doping indicating weak interaction between graphene and the Ge substrate...

The multidimensional graded response model, an item response theory (IRT) model, can be used to improve the assessment of surveys, even when sample sizes are restricted. Typically, health-based survey development utilizes classical statistical techniques (e.g. reliability and factor analysis). In a review of four prominent journals within the field of Health Psychology, we found that IRT-based models were used in less than 10% of the studies examining scale development or assessment. However, implementing IRT-based methods can provide more details about individual survey items, which is useful when determining the final item content of surveys...

Background: Knowledge creation forms an integral part of the knowledge-to-action framework aimed at bridging the gap between research and evidence-informed decision making. Although principles of science communication, data visualisation and user-centred design largely impact the effectiveness of communication, their role in knowledge creation is still limited. Hence, this article aims to provide researchers a systematic approach on how knowledge creation can be put into practice. Methods: A systematic two-phased approach towards knowledge creation was formulated and executed...

Prediction of the magnetic moment of binary body centered cubic (BCC) is explored in terms of first principle calculations and data science. A dataset of 1,541 binary BCC materials constructed by first principle calculations is implemented for data mining. Descriptors for determining the magnetic moment are explored using machine learning, where classification and regression models are both implemented. Data mining reveals that two descriptors are responsible for classifying whether the materials have zero or nonzero magnetic moments and can also classify which groups of magnetic moments they belong to ($\mu_{B}$ $<$ 1, 1 $\leq$ $\mu_{B}$ $<$2,or 2 $\leq$ $\mu_{B}$ $<$ 3) where the average scores produced in cross validation indicate 80$\%$ and 91$\%$ accuracy, respectively...

Introduction: Due to their importance in transmitting knowledge, teachers can play a crucial role in students' scientific literacy acquisition and motivation to respond to ongoing and future economic and societal challenges. However, to conduct this task effectively, teachers need to continuously improve their knowledge, and for that, a periodic update is mandatory for actualization of scientific knowledge and skills. This work is based on the outcomes of an educational study implemented with science teachers from Portuguese Basic and Secondary schools...

Background: Responsible for 25% of all US cancer deaths, lung cancer presents complex care-delivery challenges. Adoption of the highly recommended multidisciplinary care model suffers from a dearth of good quality evidence. Leading up to a prospective comparative-effectiveness study of multidisciplinary vs. serial care, we studied the implementation of a rigorously benchmarked multidisciplinary lung cancer clinic. Methods: We used a mixed-methods approach to conduct a patient-centered, combined implementation and effectiveness study of a multidisciplinary model of lung cancer care...

BACKGROUND: There is an implicit expectation for medical sciences students to work together effectively as members of health-care team, and interprofessional education is therefore widely accepted. Students' attitudes, which are affected by various factors, have been recognized as the most important predictors of successful implementation of interprofessional education with the aim of developing collaborative practice. The Readiness for Interprofessional Learning Scale has often been used in studies to measure these perspectives...

BACKGROUND: The implementation science literature has contributed important insights regarding the influence of formal policies and practices on health care innovation implementation, whereas informal implementation policies and practices have garnered little attention. The broader literature suggests that informal implementation policies and practices could also influence innovation use. PURPOSE: We used the Organizational Theory of Innovation Implementation to further understand the role of formal and informal implementation policies and practices as determinants of implementation effectiveness...

The current paper is a commentary on the Standards of Evidence for Conducting and Reporting Economic Evaluations in Prevention Science (Crowley et al. 2018). Although the standards got a lot right, some important issues were not addressed or could be explored further. Measuring rather than modeling is encouraged whenever possible. That also is in keeping with the approach taken by many prevention researchers. Pre-program planning for collection of data on resources used by individual participants (i.e., costs) is recommended, along with devotion of evaluation resources to cost assessment throughout program implementation...

We find standards useful in everyday life and in science, although we do not always follow them. Adopting new standards can be expensive, so there may be a strong incentive to maintain the status quo rather than adopt new standards. The scientific community has many standards encompassing both doing clinical research and reporting it, including standards for design and measurement. Although existing research standards have improved both research and its reporting, we need to unify existing standards and to fill the gaps between steps throughout the research process...

A key component of scientific communication is sufficient information for other researchers in the field to reproduce published findings. For computational and data-enabled research, this has often been interpreted to mean making available the raw data from which results were generated, the computer code that generated the findings, and any additional information needed such as workflows and input parameters. Many journals are revising author guidelines to include data and code availability. This work evaluates the effectiveness of journal policy that requires the data and code necessary for reproducibility be made available postpublication by the authors upon request...

Label-free imaging of rapidly moving, sub-diffraction sized structures has important applications in both biology and material science, as it removes the limitations associated with fluorescence tagging. However, unlabeled nanoscale particles in suspension are difficult to image due to their transparency and fast Brownian motion. Here we describe a novel interferometric imaging technique referred to as Magnified Image Spatial Spectrum (MISS) microscopy, which overcomes these challenges. The MISS microscope provides quantitative phase information and enables dynamic light scattering investigations with an overall optical path length sensitivity of 0...

Particle beam therapy (PBT), including proton and carbon ion therapy, is an emerging innovative treatment for cancer patients. Due to the high cost of and limited access to treatment, meticulous selection of patients who would benefit most from PBT, when compared with standard X-ray therapy (XRT), is necessary. Due to the cost and labor involved in randomized controlled trials, the model-based approach (MBA) is used as an alternative means of establishing scientific evidence in medicine, and it can be improved continuously...
