Earth's dynamo limit of predictability

Earth's magnetic field is currently decreasing, reducing the protection it offers against charged particles coming from space and increasing space weather hazards within the near‐Earth environment. Modeling the future evolution of the field is thus of considerable interest. But how far in the future this can conceivably be done is still an open question. Here we report on the first systematic investigation of the limit of predictability of fully consistent 3D numerical dynamo simulations, and suggest that the Earth's dynamo is likely unpredictable beyond a century, making decade timescale forecasts of the main magnetic field conceivable, but rendering longer‐term predictions, such as the timing of the next reversal, totally unpredictable.
Photoluminescence of an Al0.5Ga0.5As/GaAs multiple quantum well in the temperature range from 5 to 400 K

Photoluminescence (PL) of an unintentionally doped Al0.5Ga0. 5As/GaAs multiple quantum well (MQW) has been measured at temperatures from 5 to 400 K. It was found that the ratio of the intensity of the n=1 electron-light hole transition (1e-1lh) to that of the n=1 electron-heavy hole transition (1e-1hh) can be described by an exponential function of reciprocal temperature. The excitation-power dependence of the 1e-1hh transition PL intensity measured at temperatures from 5 to 296 K in steps of 15–20 K showed that the relative contribution of free-carrier recombination gradually increases from 5 to 120 K and then remains constant. This tendency was confirmed by the temperature dependence of the energy difference between the 1e-1hh transition and the bulk GaAs band gap.
DIMENSIONS OF PRE-SERVICE TEACHERS’ DIAGNOSTIC JUDGEMENTS OF STUDENT SOLUTIONS

Judgments are part of teachers’ daily practice and crucial for students’ educational careers. Previous evidence indicated that judgments are informed by various criteria. But how pre-service teachers (PSTs) judge student solutions and how these judgments are structured are still open questions. In two studies we shed light on the construct. First, we investigated PSTs’ judgements of an exemplary student solution regarding the applied categories (n 1 =110). Based on the results, we then constructed items and investigated the structure of the construct by applying EFA and CFA (n 2a =168, n 2b = 209). The results revealed the following judgment dimensions: understanding, solution quality, presentation of procedure, and motivation. In addition to evidence on the structure of the construct, we gained an instrument to measure PSTs’ judgments.

Multiplicity, Overtaking and Convergence in the Lucas Two-Sector Growth Model

This paper provides the complete closed-form solution to the Lucas two-sector model of endogenous growth. We study the issues of existence, uniqueness, multiplicity, positivity, transitional dynamics and long-run growth, related to the competitive equilibrium paths. We identify the parameter range where the different results hold and deduce the entire trajectories for the original variables. We revise the results on convergence and overtaking which arise from this model, and prove that the parameterization currently used as the background for an explanation of economic miracles and disasters, is not satisfactory because of its counterintuitive implications.
Handwriting Performance, Motor Coordination and Quality of Life Among Adolescents with Dysgraphia

Objectives: To (1) compare handwriting process measures, motor-coordination performance, and quality of life (QOL) between adolescents with dysgraphia and matched controls, as well as the correlations between those domains among individuals with dysgraphia; Further to (2) examine the contribution of handwriting process measures and motor-coordination performance to the prediction of the physical domain of QOL among adolescents with dysgraphia. Method: Participants included 80 adolescents (13–18 yr), 40 with dysgraphia and 40 matched controls. Adolescents copied a paragraph on paper affixed to a digitizer supplying objective handwriting process measures (Computerized Penmanship Evaluation Tool [ComPET]) and completed the Adult Developmental Coordination Disorder Checklist (ADC motor performance) and World Health Organization Quality of Life Questionnaire brief version (WHOQOL-BREF). Results: Significant group differences were found for the handwriting process (ComPET), motor-coordination performance (ADC), and self-perceived QOL (WHOQOL-BREF). Significant correlations were found between handwriting process measures and motor-coordination ability (ADC-C) and physical QOL. 38% of variability in the adolescent’s QOL physical domain was predicted by pen stroke height, duration and current feelings about participants’ motor-coordination performance as reflected by others. Conclusion: Results show strongly significant differences in handwriting and motor-coordination performance between adolescents with and without dysgraphia, as in aspects of QOL. Variability in physical QOL can be predicted by handwriting capabilities and motor-coordination performance.
Detection through exchange energy of multipartite entanglement in spin rings

We investigate multipartite entanglement in rings of arbitrary spins with antiferromagnetic interactions between nearest neighbors. In particular, we show that the non-degenerate ground state of rings formed by an even number ($N$) of spins is $N$-partite entangled, and exchange energy can thus be used as a multipartite-entanglement witness. We develop a general approach to compute the energy minima corresponding to biseparable states, and provide numerical results for a representative set of systems. Despite its global character, exchange energy also allows a spin-selective characterization of entanglement. In particular, in the presence of a magnetic defect, one can derive separability criteria for each individual spin, and use exchange energy for detecting entanglement between this and all the other spins.

Special Preparedness of Football Players with Different Typological Properties of Higher Parts of Central Nervous System

In modern football, the search of the criteria, which are characterized by sustainable biological nature and might be informative for the management and prediction of individual sport training, is of growing interest. We consider that individual-typological properties of higher parts of the central nervous system can meet these requirements. Thus, the goal of the research was to find out what individual-typological properties of higher parts of the central nervous system are fixed genetically and to determine their correlation with the indicators of special preparedness and bioenergetics of football players. We performed the investigation using “Diagnost-1M” and “D & K-Test” computer devices on 13 pairs of monozygotic (MZ) and 12 dizygotic (DZ) twins who did not go in for sport and 26 professional football players, and determined typological properties of the nervous system. Besides, we found physical and technical preparedness of the football players. We found the expressed hereditary conditionality for the functional mobility of the nervous processes (FMNP) (70%) and the relative predominance of genotypic factors (50%) for the strength of the nervous processes (SNP) and the equilibrium of the nervous processes (ENP). We determined the predominance of phenotypic factors (30%) for the indicators of sensorimotor reactions. The indicators of bioenergetics metabolism, physical and technical preparedness, expert evaluation of game activity of the highly qualified football players depended on the genetically determined properties – the functional mobility of the nervous processes.
Modeling the distribution of coprophagous beetle species in the Western Swiss Alps

Coprophagous beetles are essential for fecal matter removal and are thus considered key ecosystem services providers. Yet, our knowledge of these beetles’ distribution and ecology remains very limited. Here, we used Species Distribution Models (SDM) to investigate the species-environment relationships (i.e. their niche) and predict the geographic distribution of coprophagous beetles in the Western Swiss Alps. We used our own sampled data and existing national data from the Swiss faunal database to calibrate, for each species, a regional and a national SDM respectively. In both models, the best predictors were temperature and rock cover proportion, while a soil characteristic (∂ 13 C) indicating its organic content and texture was important in the regional models and pre-cipitations in the Swiss models. The model performed better for species specialized on low or high altitudes than for generalist species occurring in a large altitudinal range. The model performances were neither influenced by the size, nor by the nesting behavior (laying eggs inside or below the excrements) of the species. We also showed that species richness decreased with altitude. This study opens new perspective for a better knowledge of coprophagous beetle’s ecology and a useful tool for their conservation in mountain regions.
The diffusive idealization of charged-particle transport in random magnetic fields. [cosmic ray propagation]

The transport of charged particles diffusing in a random magnetic field parallel to a relatively large guiding field is presented. The same coefficient of diffusion is obtained by three methods. Two corrections must be added to the expression in which the diffusive flux is proportional to the gradient of the density. Explicit expressions are given for a characteristic time and a characteristic length which describe the corrections. The well known divergence of the coefficient of diffusion, which is implied by the quasilinear analysis of pitch angle scattering, does not occur if the scattering rate is finite at 90 deg pitch angle. This effect is illustrated by formulas which give the coefficient of diffusion when the quasilinear expression is perturbed by a variable amount of isotropic scattering.
Enhanced spectroscopic gas sensors using in-situ grown carbon nanotubes

In this letter, we present a fully complementary-metal-oxide-semiconductor (CMOS) compatible microelectromechanical system thermopile infrared (IR) detector employing vertically aligned multi-walled carbon nanotubes (CNT) as an advanced nano-engineered radiation absorbing material. The detector was fabricated using a commercial silicon-on-insulator (SOI) process with tungsten metallization, comprising a silicon thermopile and a tungsten resistive micro-heater, both embedded within a dielectric membrane formed by a deep-reactive ion etch following CMOS processing. In-situ CNT growth on the device was achieved by direct thermal chemical vapour deposition using the integrated micro-heater as a micro-reactor. The growth of the CNT absorption layer was verified through scanning electron microscopy, transmission electron microscopy, and Raman spectroscopy. The functional effects of the nanostructured ad-layer were assessed by comparing CNT-coated thermopiles to uncoated thermopiles. Fourier transform IR spectro.

number of projects in support of business, entrepreneurship and new technologies; number of implemented investment projects. This report summarises the work and lessons learnt by the Mutual Learning Exercise (MLE) on Evaluation of Complex Public-Private Partnership (PPP) Programmes in STI. MLE is a project-based learning process whereby participating countries, assisted by a small group of experts, jointly examine a challenge-driven question in more detail. Belgium/Flanders, Bulgaria, Norway, and Sweden were the participant countries in this exercise. The MLE project addressed PPPs which are strategic (often virtual) centres or network type of organisations for promoting sector- or challenge-based research involving multiple partners and promoting public-private collaboration in STI. The MLE examined the PPPs within a policy cycle frame, drawing on available knowledge on public-private partnerships in research and evaluation literature, and lessons learnt on the concrete cases and experiences of the participating countries
Integrating Cerebro with Ray

Cerebro is a model selection system that introduced the concept of model hopper parallelism (MOP), which is a strategy that inherits the upsides of data parallelism and task parallelism but not their downsides. Cerebro allows for the addition of new execution backends, which can be done by implementing a new class that extends its abstract Backend class. Using Ray, an API for building distributed applications in Python, we have created an additional backend that performs Model Hopper Parallelism for scalable and efficient model selection on deep learning models created with standard Python machine learning libraries. Our work includes sharding the processed training data across multiple machines and implementing MOP over the different models on these shards.

MARKET POTENTIAL OF UNCONVENTIONAL WIND TURBINES. A TECHNOLOGY REVIEW

: The paper presents an in-depth analysis regarding the market potential of unconventional wind turbines from a technological perspective. The envisaged solutions were identified in literature and are currently in different development stages. The aim of the analysis is to estimate which types of wind turbines are suitable for further development and have the potential to replace someday the traditional vertical axis wind turbines with three blades that currently represent the best solution for onshore and offshore wind farms. The development of wind power conversion solutions is a current topic due to low carbon energy policies and presents several challenges. Essentially, it needs to be cost competitive compared with fossil fuels technologies and other renewable energy sources, especially photovoltaic (PV) power plants that recently gained ground due to a continuous reduction of manufacturing costs. Both the PV and wind turbines must have a complementary approach for a good energy mix. The technology of the wind turbines of today is continuously improved in order to increase their competitiveness on the market. Further developments are expected both for large capacity wind turbines and for low power concepts while the reliability over time will determine the best solution that will be adopted and maintained for years to come. Not all the solutions can have future development potential, but some results and approaches can be applied in the industry having a positive impact in terms of production cost and energy conversion efficiency.

A Software Development Process by Integrating Agile Methodology with Cloud Computing

: In a current era, the software industry is very dynamic in nature . The organizations are repetitively changes their software requirements to adjust with current environment. They demands not only for fast delivery of software products but also for accepting changing requirements. In this aspect, agile methodologies are very auspicious in software industry. Agile method encourage evolutionary development and delivery, iterative approach, rapid and flexible response to change and adaptive planning. Again the cloud computing plays an important role in an organization. It helps to reduces burden on hardware, to speed-up operations, makes software more manageable, makes easier for clients to access various services, to reduce cost and to provide data center storage solutions. However, cloud development is not easy task for several software engineering projects like the project that need to change depend upon reusability. In this paper, we have integrated the agile technology with the cloud-computing model, which is helpful to minimize the development cost, to satisfy customer’s requirement and improve the reusability. Agile technology enhance the opportunity provided by cloud computing via releases software iteratively and receiving user feedback more frequently.
LINGUISTIC CONTRASTS OUT OF CONSCIOUS CONTROL 

: This paper looks at how learners discover semantic and pragmatic contrasts between newly learned language forms. Following the Principle of Contrast , the discovery of contrasts is assumed to be a prerequisite to learning both single words and formulaic expressions. Are lexical items recorded as memory traces with or without conscious effort in the sense of the Noticing Hypothesis ? The main claim is that the amount of detail to be extracted from input exceeds the capacity of conscious awareness. Instead, people rely on the mechanism of repetition detection, without conscious control.
