  • Upslope migration of snow avalanches in a warming climate Tue, 26 Oct 2021 06:00:00 -0400
    Snow is highly sensitive to atmospheric warming. However, because of the lack of sufficiently long snow avalanche time series and statistical techniques capable of accounting for the numerous biases inherent to sparse and incomplete avalanche records, the evolution of process activity in a warming climate remains little known. Filling this gap requires innovative approaches that put avalanche activity into a long-term context. Here, we combine extensive historical records and Bayesian techniques...
  • An adapted scale to evaluate insight in Prader-Willi Syndrome Tue, 26 Oct 2021 06:00:00 -0400
    CONCLUSIONS: The Adapted version for Prader-Willi patients of the Scale of Unawareness of Mental Disorder (APW-SUD) showed adequate psychometric properties and it is an easy to administer means to assess insight in this population.
  • Effectiveness of Mandatory and Incentive-Based Routine Childhood Immunization Programs in Europe: A Systematic Review of the Literature Tue, 26 Oct 2021 06:00:00 -0400
    There is a lack of comprehensive and systematic data and evidence regarding the effectiveness of mandatory and incentive-based vaccination schemes. The results of such programs in some countries have not been adequately studied. A number of countries have recently introduced tightening vaccination measures, and it is important to analyze and assess the results of these programs. The unprecedented situation due to the COVID-19 pandemic and mass vaccination made the topic of the effectiveness of...
  • A linear mixed model to estimate COVID-19-induced excess mortality Mon, 25 Oct 2021 06:00:00 -0400
    The Corona Virus Disease (COVID-19) pandemic has increased mortality in countries worldwide. To evaluate the impact of the pandemic on mortality, the use of excess mortality rather than reported COVID-19 deaths has been suggested. Excess mortality, however, requires estimation of mortality under non-pandemic conditions. Although many methods exist to forecast mortality, they are either complex to apply, require many sources of information, ignore serial correlation, and/or are influenced by...
  • The attitudes of elementary and middle school students and teachers towards online learning during the corona pandemic outbreak Mon, 25 Oct 2021 06:00:00 -0400
    The coronavirus pandemic has impacted the education systems worldwide and most, including the Israeli, have transitioned to online learning. Moreover, closing schools has extreme social, cultural, educational and economic implications on the student, teacher and parent populations. This is especially true for students from families of lower-socio-economic status and young students who need parental assistance. Furthermore, online learning is not suitable for all teachers, because some lack the...
  • Calculation of the space charge distribution in poled soda-lime glass Mon, 25 Oct 2021 06:00:00 -0400
    An analytical model of electric field assisted diffusion of ions into a multi-component glass is extended to calculate the space charge that forms between the poled layer and the potassium peak in a poled soda-lime glass. The model is compared with numerical solutions to the drift-diffusion equations and Poisson's equation and shows good agreement. Some recent experimental results in corona poled soda-lime glass are also discussed using this model.
  • Chemical Composition and Strain at Interfaces between Different Morphologies in Block Copolymer Thin Films Mon, 25 Oct 2021 06:00:00 -0400
    Transitional composition between two thin-film morphologies of the block copolymer, polystyrene-block-poly(tert-butyl acrylate) (PS-b-PtBuA), was investigated using near-field infrared spectroscopy and atomic force microscopy mechanical measurements. These techniques allowed block identification with nanoscale spatial resolution and elucidated the material's sub-surface composition. PS was found to form coronae around the PtBuA block in spherical valleys on flat areas of the film, and coronae of...
  • Subjective Symptoms in Magnetic Resonance Imaging Personnel: A Multi-Center Study in Italy Mon, 25 Oct 2021 06:00:00 -0400
    Introduction: Magnetic Resonance Imaging (MRI) personnel have significant exposure to static and low-frequency time-varying magnetic fields. In these workers an increased prevalence of different subjective symptoms has been observed. The aim of our study was to investigate the prevalence of non-specific subjective symptoms and of "core symptoms" in a group of MRI personnel working in different centers in Italy, and of possible relationships with personal and occupational characteristics....
  • Searching for urban mobilities futures. Methodological innovation in the light of COVID-19 Mon, 25 Oct 2021 06:00:00 -0400
    The global Covid-19 crisis reveals the very nature of the mobilized and interconnected risk society. Media discourse, everyday talk, science and arts process daunting questions such as Can we live a "normal" life, again?, What exactly will happen when the Corona pandemic becomes less dangerous? Can business, public and everyday life go back to how they used to be? These questions open up possibilities to rethink current forms of urban planning. In many ways this needs sophisticated methodologies...
  • Transportation of AIE-visualized nanoliposomes is dominated by the protein corona Mon, 25 Oct 2021 06:00:00 -0400
    Liposomes, especially cationic liposomes, are the most common and well-investigated nanocarriers for biomedical applications, such as drug and gene delivery. Like other types of nanomaterials, once liposomes are incubated in a biological milieu, their surface can be immediately cloaked by biological components to form a protein corona, which confers a new 'biological identity' and modulates downstream interactions with cells. However, it remains unclear how the protein corona affects the...
