To describe the immunogenicity and safety of a tetravalent dengue vaccine (TAK-003) in healthy adolescents living in Mexico City, an area considered non-endemic for dengue (NCT03341637).Participants aged 12-17 years were randomized 3:1 to receive two doses (Month 0 and Month 3) of TAK-003 or placebo. Immunogenicity was assessed by microneutralization assay of dengue neutralizing antibodies at baseline, Months 4 and 9. Solicited and unsolicited adverse events (AEs) were recorded after each vaccination. ...

The computational modeling of softening materials is still a challenging subject.An interesting way to deal with this problem is to adopt a variational framework.However, there are appealing features in using a classical approach.We explore the possibilities of both frameworks to include dissipative mechanisms.We start with a one-dimensional variational plastic-damage model rewritten in a classical framework, where regularization through viscoplasticity is applied.We highlight the appearance of ...

For new generations to fully integrate and participate in an increasingly technology-rich society they must become digitally literate. Education systems have a role to play in this, especially given the growing evidence of a digital divide. Through this study, we look to identify and characterize factors related to the digital skills of 10th grade Chilean students, as measured by a national standardized test. A mixed methodology was used to explore these factors and provide a more detailed analysis. ...

School dropout is a structural problem which permanently penalizes students and society in areas such as low qualification jobs, higher poverty levels and lower life expectancy, lower pensions, and higher economic burden for governments. Given these high consequences and the surge of the problem due to COVID-19 pandemic, in this paper we propose a methodology to design, develop, and evaluate a machine learning model for predicting dropout in school systems. In this methodology, we introduce necessary ...

Modeling complex material failure with competing mechanisms is a difficult task that often leads to mathematical and numerical challenges. This work contributes to the study of localized failure mechanisms by means of phase fields in a variational framework: in addition to the treatment of brittle and ductile fracture, done in previous work, we consider the case of shear band formation followed by ductile fracture. To achieve this, a new degradation function is introduced, which distinguishes between ...

This paper addresses the modeling of fracture in quasi-brittle materials using a phase-field approach to the description of crack topology. Within the computational mechanics community, several studies have treated the issue of modeling fracture using phase fields. Most of these studies have used an approach that implies the lack of a damage threshold. We herein explore an alternative model that includes a damage threshold and study how it compares with the most popular approach. The formulation ...

The modeling of the post-critical behavior of materials is still a scientific challenge. This is especially true when dealing with materials that undergo complex behavior, in which several mechanisms are combined. This physical complexity is reflected in the mathematics and the numerics of this kind of problems. In this work, we study the modeling of brittle and ductile fracture. We adopt regularized kinematics based on a phase field description of the fracture topology. In order to ensure mathematical ...

Currently, the use of information and communication technologies (ICT) in education does not conclusively demonstrate significant effects on learning. However, not all ICT usage models are designed to affect student outcomes. Therefore, to accurately study the impact of ICT, the concept of an educational programme supported by ICT must first be defined. The authors propose the ICT for Education (ICT4E) programme, an evidence-based framework to determine a model's ability to produce improvements before ...

Abstract The impact of information and communication technology (ICT) in primary and secondary education is still an open question. Following review of the available literature, we classify the causes of the lack of impact on students' attainment in four dimensions: (1) the design and implementation of ICT in educational settings; (2) the evaluation of its impact; (3) the scaling up of these kinds of innovations; and (4) the cost‐effectiveness of technology‐enhanced learning environments. Based on this ...

More than 20 years after ICTs were introduced in schools, solid evidence of their impact on student attainment is still lacking. Reasons for this include the mismatch between the methods used to measure the effects and the type of learning promoted, the absence of information regarding the specific types of ICT used, and the scarce attention paid to the monitoring and evaluation of ICT for Education (ICT4E) programs. A monitoring and evaluation scheme would provide qualitative and quantitative data ...

Abstract Efforts to improve the educational process must focus on those most responsible for implementing it: the teachers. It is with them in mind that we propose a face‐to‐face computer‐supported collaborative learning system that uses wirelessly networked hand‐held computers to create an environment for helping students assimilate and transfer educational content. Two applications of this system are presented in this paper. The first involves the use of the system by students, transforming classroom ...

However, there is no clear consensus on how to evaluate these new technologies. This paper proposes a comprehensive methodology for estimating the value of a new educational technology in three steps: benefit analysis, through the administration of a well-designed experiment; cost analysis, which incorporates costs to weigh against the benefits; and feasibility ...

Abstract A survey of copper levels in agricultural soils of central Chile revealed two soil clusters—one with a mean copper level of 162 mg/kg and one with a mean copper level of 751 mg/kg of soil. Samples of soils from both soil clusters were characterized on the basis of physicochemical characteristics, and copper extractability was compared by saturation and CaCl 2 extraction as well as an acid‐leaching procedure (TCLP). We also measured the copper content of various tissues of tomato ( Lycopersicon ...

The binding of ligands to phosphofructokinase 2 (Pfk-2) from Escherichia coli induces changes in the fluorescence emission properties of its single tryptophan residue, Trp88, suggesting that upon binding the protein undergoes a conformational change. This fluorescence probe was used to determine the presence of an allosteric site for MgATP2- in the enzyme. Fructose 6-phosphate (fructose-6-P), the first substrate that binds to the enzyme with an ordered bi-bi mechanism, increases the fluorescence up ...

Current evidence suggests that extracellular mannose can be transported intracellularly and utilized for glycoprotein synthesis; however, the identity and the functional characteristics of the transporters of mannose are controversial. Although the glucose transporters are capable of transporting mannose, it has been postulated that the entry of mannose in mammalian cells is mediated by a transporter that is insensitive to glucose [Panneerselvam, K., and Freeze, H.

Many metals (aluminum, cadmium, cobalt, copper, nickel, lead, zinc) are widely studied environmental contaminants because of their ubiquity, potential toxicity to aquatic life, and tendency for toxicity to vary widely as a function of water chemistry. The interactions between metal and water chemistry influence metal "bioavailability," an index of the rate and extent to which the metal reaches the site of toxic action. The implications of metal bioavailability for ecological risk assessment are large, ...
