Critical Minerals for Zero-Emission Transportation.

Fundamentals of critical minerals and their paramount role in the successful deployment of clean energy technologies in future transportation are assessed along with current global efforts to satisfy the needs of automotive supply chains and environmental concerns. An implementation of large quantities of minerals, in particular metals, into the manufacturing of strategic components of zero-emission vehicles will bring new challenges to energy security. As a result, a reduced dependency on conventional hydrocarbon resources may lead to new and unexpected interdependencies, including dependencies on raw materials.

Understanding the Pathway of Cancer Information Seeking: Cancer Information Services as a Supplement to Information from Other Sources.

Cancer information services (CISs) can play an important role within the pathway of cancer information seeking, but so far, this role is not well understood. Callers (n = 6,255) who contacted the largest provider of cancer information in Germany participated in a survey in which they reported their information sources, information level, and needs leading to the call. Persons with prior information from a physician (n = 1,507) were compared to people with prior online information (n = 901) and people with prior information from both sources (n = 2,776).

Current Trends in Automotive Lightweighting Strategies and Materials.

The automotive lightweighting trends, being driven by sustainability, cost, and performance, that create the enormous demand for lightweight materials and design concepts, are assessed as a part of the circular economy solutions in modern mobility and transportation. The current strategies that aim beyond the basic weight reduction and cover also the structural efficiency as well as the economic and environmental impact are explained with an essence of guidelines for materials selection with an eco-friendly approach, substitution rules, and a paradigm of the multi-material design. Particular attention is paid to the metallic alloys sector and progress in global R&D activities that cover the "lightweight steel", conventional aluminum, and magnesium alloys, together with well-established technologies of components manufacturing and future-oriented solutions, and with both adjusting to a transition from internal combustion engines to electric vehicles.

Correlates of the perceived quality of patient-provider communication among German adults.

Background: Since a higher perceived quality of patient-provider communication is known to be associated with improved health outcomes, it is essential to analyze determinants influencing patients' perceived quality of patient-provider communication. Due to the limited knowledge about patient-related influencing factors of quality perception available so far, the objective of this study is to explore and assess determinants of the perceived quality of patient-provider communication with regards to sociodemographic, health-related, healthcare-specific and information-related factors.

Methods: Linear regression of cross-sectional data from the first wave of Health Information National Trends Survey Germany (n = 2902) was conducted.

[How do people in Germany seek health information? Insights from the first wave of HINTS Germany].

Background: Dynamic developments in the healthcare system are associated with a more active and more participatory patient role, in which patients make informed decisions and help shape their care. This points to the increasing role of health information and health information seeking behaviors. But to date, the health information seeking behavior of people in Germany hasn't been subject to systematic survey research.

High-throughput cell and spheroid mechanics in virtual fluidic channels.

Microfluidics by soft lithography has proven to be of key importance for biophysics and life science research. While being based on replicating structures of a master mold using benchtop devices, design modifications are time consuming and require sophisticated cleanroom equipment. Here, we introduce virtual fluidic channels as a flexible and robust alternative to microfluidic devices made by soft lithography.

Demographic and cancer-related differences between self-seeking patients and supported patients: Analysis of cancer information-service data.

Objective: Surrogate information seeking is quite common, and several studies have presented data on caregivers, family members, and friends who seek health information on the Internet or from a cancer-information service (CIS) on behalf of cancer patients. However, these studies provide little information about the patients who are supported by surrogate seekers. Therefore, this study analyzed demographic and cancer-related differences, including diverse informational needs, between self-seeking patients and patients who benefited from surrogate seekers (ie, caregivers, family, or friends) requesting information on their behalf.

High-throughput single-cell rheology in complex samples by dynamic real-time deformability cytometry.

In life sciences, the material properties of suspended cells have attained significance close to that of fluorescent markers but with the advantage of label-free and unbiased sample characterization. Until recently, cell rheological measurements were either limited by acquisition throughput, excessive post processing, or low-throughput real-time analysis. Real-time deformability cytometry expanded the application of mechanical cell assays to fast on-the-fly phenotyping of large sample sizes, but has been restricted to single material parameters as the Young's modulus.

Effectiveness of a school-based intervention to prevent child sexual abuse-Evaluation of the German IGEL program.

Background: Child sexual abuse (CSA) is a problem with severe consequences for victimized children. A variety of interventions have been developed and implemented over the last decades to prevent CSA. However, most of them have not been systematically evaluated to determine their effectiveness.

Gender-Specific Determinants and Patterns of Online Health Information Seeking: Results From a Representative German Health Survey.

Background: Online health information-seeking behavior (OHISB) is currently a widespread and common behavior that has been described as an important prerequisite of empowerment and health literacy. Although demographic factors such as socioeconomic status (SES), age, and gender have been identified as important determinants of OHISB, research is limited regarding the gender-specific motivational determinants of OHISB and differences between women and men in the use of online resources for health information purposes.

Objective: The aim of this study was to identify gender-specific determinants and patterns of OHISB by analyzing data from a representative German sample of adults (N=1728) with special attention to access and frequency of use as well as topics and sources of OHISB.

Individual and school level correlates of moderate to vigorous physical activity among school-children in Germany--a multi-level analysis.

Background: Young people spend half of their days in school, but evidence concerning the influence of school environment on the physical activity (PA) of pupils is still inconsistent. A better understanding of potential correlates of PA on the school-level and their possible interaction with individual aspects is needed to improve the development of more effective interventions.

Methods: We used data from the 2009/10 German Health Behaviour in School-aged Children study (HBSC)-sample (n=5,005 students aged 11-15 years) including self-reported moderate to vigorous intensity PA as well as a variety of biological, demographic and behavioral correlates and matched them with school-level data from the national school principals' HBSC questionnaire.

Myxococcus xanthus gliding motors are elastically coupled to the substrate as predicted by the focal adhesion model of gliding motility.

Myxococcus xanthus is a model organism for studying bacterial social behaviors due to its ability to form complex multi-cellular structures. Knowledge of M. xanthus surface gliding motility and the mechanisms that coordinated it are critically important to our understanding of collective cell behaviors.

A versatile class of cell surface directional motors gives rise to gliding motility and sporulation in Myxococcus xanthus.

Eukaryotic cells utilize an arsenal of processive transport systems to deliver macromolecules to specific subcellular sites. In prokaryotes, such transport mechanisms have only been shown to mediate gliding motility, a form of microbial surface translocation. Here, we show that the motility function of the Myxococcus xanthus Agl-Glt machinery results from the recent specialization of a versatile class of bacterial transporters.
