An alternative approach to the Boltzmann distribution through the chemical potential

NASA Astrophysics Data System (ADS)

D'Anna, Michele; Job, Georg

2016-05-01

The Boltzmann distribution is one of the most significant results of classical physics. Despite its importance and its wide range of application, at high school level it is mostly presented without any derivation or link to some basic ideas. In this contribution we present an approach based on the chemical potential that allows to derive it directly from the basic idea of thermodynamical equilibrium.

Developing conceptions of food and nutrition

NASA Astrophysics Data System (ADS)

Francis, Rod; Hill, Doug

1993-12-01

This paper describes an investigation of concepts that various groups hold about food and nutrition. Groups investigated were students in Years 4 and 8, university students in a BEd (primary) program and parents of the Year 4 students. It was found that for many important concepts relating to food selection, the basic ideas of each group were surprisingly consistent, despite the influence of formal education. In particular, misconception about energy and its role in nutrition and particular food groups was an important finding. Implications for school and community education are drawn from the results.

Narrative ideas for consulting with communities and organizations: ripples from the gatherings.

PubMed

Freedman, Jill; Combs, Gene

2009-09-01

This paper reviews Michael White's early work with communities and extends ideas and practices from that work into the realm of consulting with organizations. We draw on Michael's writing and the records of two specific projects, as well as the recollections of team members in those projects, to describe how ideas and practices that were originally developed in working with individuals and families came to be applied in community settings. Specifically, we show how the central intention of the work is to use narrative ideas and practices in ways that allow communities to articulate, appreciate, document, utilize, and share their own knowledges of life and skills of living. We discuss the basic narrative ideas of stories, double listening, telling and retelling, making documents, and linking lives through shared purposes. For these projects, the teams developed structures that made it possible to use the basic idea with whole communities. We show how this work with communities has offered inspiration and ideas for our work in consulting to organizations. Finally, we describe and illustrate a particular way of working with organizations that carries the spirit of Michael's community work into situations requiring shorter blocks of time and more limited commitments than the original community contexts.

In search of a metatheory for cognitive development (or, Piaget is dead and I don't feel so good myself).

PubMed

Bjorklund, D F

1997-02-01

With the waning of influence of Piaget's theory and the shortcomings of information-processing perspectives of cognitive growth, cognitive developmentalists lack a common set of broad, overarching principles and assumptions--a metatheory--to guide their research. Developmental biology is suggested as metatheory for cognitive development. Although it is important for developmentalists to understand proximal biological causes (e.g., brain development), most important for such a metatheory is an evolutionary perspective. Some basic principles of evolutionary psychology are introduced, and examples of contemporary research and theory consistent with these ideas are provided.

Cooperative vehicle routing problem: an opportunity for cost saving

NASA Astrophysics Data System (ADS)

Zibaei, Sedighe; Hafezalkotob, Ashkan; Ghashami, Seyed Sajad

2016-09-01

In this paper, a novel methodology is proposed to solve a cooperative multi-depot vehicle routing problem. We establish a mathematical model for multi-owner VRP in which each owner (i.e. player) manages single or multiple depots. The basic idea consists of offering an option that owners cooperatively manage the VRP to save their costs. We present cooperative game theory techniques for cost saving allocations which are obtained from various coalitions of owners. The methodology is illustrated with a numerical example in which different coalitions of the players are evaluated along with the results of cooperation and cost saving allocation methods.

Attending to items in working memory: Evidence that refreshing and memory search are closely related

PubMed Central

Vergauwe, Evie; Cowan, Nelson

2014-01-01

Refreshing refers to the use of attention to reactivate items in working memory (WM). The current study aims at testing the hypothesis that refreshing is closely related to memory search. The assumption is that refreshing and memory search both rely on a basic covert memory process that quickly retrieves the memory items into the focus of attention, thereby reactivating the information (Cowan, 1992; Vergauwe & Cowan, 2014). Consistent with the idea that people use their attention to prevent loss from WM, previous research has shown that increasing the proportion of time during which attention is occupied by concurrent processing, thereby preventing refreshing, results in poorer recall performance in complex span tasks (Barrouillet, Portrat, & Camos, 2011). Here, we tested whether recall performance is differentially affected by prolonged attentional capture caused by memory search. If memory search and refreshing both rely on retrieval from WM, then prolonged attentional capture caused by memory search should not lead to forgetting because memory items are assumed to be reactivated during memory search, in the same way as they would if that period of time were to be used for refreshing. Consistent with this idea, prolonged attentional capture had a disruptive effect when it was caused by the need to retrieve knowledge from long-term memory but not when it was caused by the need to search through the content of WM. The current results support the idea that refreshing operates through a process of retrieval of information into the focus of attention. PMID:25361821

Some remarks on a current study involving preservice elementary teachers and some basic astronomical phenomena

NASA Astrophysics Data System (ADS)

Gangui, Alejandro; Iglesias, María; Quinteros, Cynthia

2011-06-01

Recent studies have shown that not only primary school students but also their future teachers reach science courses with pre-constructed and consistent models of the world surrounding them. These ideas include many misconceptions which turn out to be robust and hence make difficult an appropriate teaching-learning process. We have designed some tools (and show here results with a questionnaire) that proved helpful in putting in evidence some of the most frequently used alternative models on a few basic astronomical notions. We have tested this questionnaire with preservice elementary teachers from various normal schools in Buenos Aires and made a first analysis of the results. The collection of data recovered so far shows that some non-scientific conceptions are indeed part of the prospective teachers' (scientific) background and, therefore, that the issue deserves special attention during their formal training.

``Physics with a Smile''-Explaining Phenomena with a Qualitative Problem-Solving Strategy

NASA Astrophysics Data System (ADS)

Mualem, Roni; Eylon, Bat-Sheva

2007-03-01

Various studies indicate that high school physics students and even college students majoring in physics have difficulties in qualitative understanding of basic concepts and principles of physics.1-5 For example, studies carried out with the Force Concept Inventory (FCI)1,6 illustrate that qualitative tasks are not easy to solve even at the college level. Consequently, "conceptual physics" courses have been designed to foster qualitative understanding, and advanced high school physics courses as well as introductory college-level courses strive to develop qualitative understanding. Many physics education researchers emphasize the importance of acquiring some qualitative understanding of basic concepts in physics as early as middle school or in the context of courses that offer "Physics First" in the ninth grade before biology or chemistry.7 This trend is consistent with the call to focus the science curriculum on a small number of basic concepts and ideas, and to instruct students in a more "meaningful way" leading to better understanding. Studies7-10 suggest that familiar everyday contexts (see Fig. 1) are useful in fostering qualitative understanding.

Parental alignments and rejection: an empirical study of alienation in children of divorce.

PubMed

Johnston, Janet R

2003-01-01

This study of family relationships after divorce examined the frequency and extent of child-parent alignments and correlates of children's rejection of a parent, these being basic components of the controversial idea of "parental alienation syndrome." The sample consisted of 215 children from the family courts and general community two to three years after parental separation. The findings indicate that children's attitudes toward their parents range from positive to negative, with relatively few being extremely aligned or rejecting. Rejection of a parent has multiple determinants, with both the aligned and rejected parents contributing to the problem, in addition to vulnerabilities within children themselves.

PDB data curation.

PubMed

Wang, Yanchao; Sunderraman, Rajshekhar

2006-01-01

In this paper, we propose two architectures for curating PDB data to improve its quality. The first one, PDB Data Curation System, is developed by adding two parts, Checking Filter and Curation Engine, between User Interface and Database. This architecture supports the basic PDB data curation. The other one, PDB Data Curation System with XCML, is designed for further curation which adds four more parts, PDB-XML, PDB, OODB, Protin-OODB, into the previous one. This architecture uses XCML language to automatically check errors of PDB data that enables PDB data more consistent and accurate. These two tools can be used for cleaning existing PDB files and creating new PDB files. We also show some ideas how to add constraints and assertions with XCML to get better data. In addition, we discuss the data provenance that may affect data accuracy and consistency.

Holloway, C. M.

1986-01-01

Research in the area of functional programming languages has intensified in the 8 years since John Backus' Turing Award Lecture on the topic was published. The purpose of this paper is to present a survey of the ideas of functional programming languages. The paper assumes the reader is comfortable with mathematics and has knowledge of the basic principles of traditional programming languages, but does not assume any prior knowledge of the ideas of functional languages. A simple functional language is defined and used to illustrate the basic ideas. Topics discussed include the reasons for developing functional languages, methods of expressing concurrency, the algebra of functional programming languages, program transformation techniques, and implementations of functional languages. Existing functional languages are also mentioned. The paper concludes with the author's opinions as to the future of functional languages. An annotated bibliography on the subject is also included.

An IDEA for Short Term Outbreak Projection: Nearcasting Using the Basic Reproduction Number

PubMed Central

Fisman, David N.; Hauck, Tanya S.; Tuite, Ashleigh R.; Greer, Amy L.

2013-01-01

Background Communicable disease outbreaks of novel or existing pathogens threaten human health around the globe. It would be desirable to rapidly characterize such outbreaks and develop accurate projections of their duration and cumulative size even when limited preliminary data are available. Here we develop a mathematical model to aid public health authorities in tracking the expansion and contraction of outbreaks with explicit representation of factors (other than population immunity) that may slow epidemic growth. Methodology The Incidence Decay and Exponential Adjustment (IDEA) model is a parsimonious function that uses the basic reproduction number R0, along with a discounting factor to project the growth of outbreaks using only basic epidemiological information (e.g., daily incidence counts). Principal Findings Compared to simulated data, IDEA provides highly accurate estimates of total size and duration for a given outbreak when R0 is low or moderate, and also identifies turning points or new waves. When tested with an outbreak of pandemic influenza A (H1N1), the model generates estimated incidence at the i+1th serial interval using data from the ith serial interval within an average of 20% of actual incidence. Conclusions and Significance This model for communicable disease outbreaks provides rapid assessments of outbreak growth and public health interventions. Further evaluation in the context of real-world outbreaks will establish the utility of IDEA as a tool for front-line epidemiologists. PMID:24391797

Thinking as the control of imagination: a conceptual framework for goal-directed systems.

PubMed

Pezzulo, Giovanni; Castelfranchi, Cristiano

2009-07-01

This paper offers a conceptual framework which (re)integrates goal-directed control, motivational processes, and executive functions, and suggests a developmental pathway from situated action to higher level cognition. We first illustrate a basic computational (control-theoretic) model of goal-directed action that makes use of internal modeling. We then show that by adding the problem of selection among multiple action alternatives motivation enters the scene, and that the basic mechanisms of executive functions such as inhibition, the monitoring of progresses, and working memory, are required for this system to work. Further, we elaborate on the idea that the off-line re-enactment of anticipatory mechanisms used for action control gives rise to (embodied) mental simulations, and propose that thinking consists essentially in controlling mental simulations rather than directly controlling behavior and perceptions. We conclude by sketching an evolutionary perspective of this process, proposing that anticipation leveraged cognition, and by highlighting specific predictions of our model.

The Well-being Conception of Health and the Conflation Problem.

PubMed

de Campos, Thana C

2016-04-01

Human rights advocates often use inflated and thus underspecified terminologies when addressing the content of their claims. One example of such loose terminology is the term 'well-being', as currently employed in connection with a definition for the right to health. What I call the 'well-being conception of health' conflates the distinct ideas of basic and non-basic health needs, as well as those of individual autonomy and freedom. I call this the conflation problem. This paper argues for the need of an understanding of the right to health, nuanced enough to capture not only these distinct ideas, but also their moral relevance for the common good.

Analysis of Students' Conceptions of Basic Magnetism from a Complex Systems Perspective

NASA Astrophysics Data System (ADS)

Lemmer, Miriam; Kriek, Jeanne; Erasmus, Benita

2018-03-01

This study established whether 12 South African secondary school physics students had incorrect conceptions of basic magnetism and if they had, to what extent they consistently applied such conceptions. Different scenarios in the form of thought experiments were presented in a clinical interview approach. A complex systems perspective underpinned the study and was firstly used to analyze 12 students' conceptions in terms of intuitive fragments of knowledge elements, structured misconceptions, and theory-like system of knowledge elements. Secondly, coherence in each student's ideas expressed across ten themes using thought experiments was analyzed in an effort to determine variations or coherence in responses. Examples of student explanations and sketches are discussed in the paper to illustrate the conceptual structures they applied. Most of the students in this study used a variety of knowledge elements in accord with a complex systems perspective, but three students seemed to prefer a specific perspective. One student's ideas tended to be mainly fragmented, a second exposed a number of structured misconceptions, while another student's reasoning can be described as a theory-like system of knowledge elements. Accordingly, the emphasis of physics education research should no longer be on the compilation of a list of misconceptions that have to be remedied or replaced, but on the conceptual connections, students make and their associative reasoning patterns (i.e., knowledge systems revealed). It remains for the teacher to use the complex systems perspective as a framework to facilitate students' conceptual development and understanding, proceeding on their existing knowledge systems.

Characterizing the changes in teaching practice during first semester implementation of an argument-based inquiry approach in a middle school science classroom

NASA Astrophysics Data System (ADS)

Pinney, Brian Robert John

The purpose of this study was to characterize ways in which teaching practice in classroom undergoing first semester implementation of an argument-based inquiry approach changes in whole-class discussion. Being that argument is explicitly called for in the Next Generation Science Standards and is currently a rare practice in teaching, many teachers will have to transform their teaching practice for inclusion of this feature. Most studies on Argument-Based Inquiry (ABI) agree that development of argument does not come easily and is only acquired through practice. Few studies have examined the ways in which teaching practice changes in relation to the big idea or disciplinary core idea (NGSS), the development of dialogue, and/or the development of argument during first semester implementation of an argument-based inquiry approach. To explore these areas, this study posed three primary research questions: (1) How does a teacher in his first semester of Science Writing Heuristic professional development make use of the "big idea"?, (1a) Is the indicated big idea consistent with NGSS core concepts?, (2) How did the dialogue in whole-class discussion change during the first semester of argument-based inquiry professional development?, (3) How did the argument in whole-class discussion change during the first semester of argument-based inquiry professional development? This semester-long study that took place in a middle school in a rural Midwestern city was grounded in interactive constructivism, and utilized a qualitative design to identify the ways in which the teacher utilized big ideas and how dialogue and argumentative dialogue developed over time. The purposefully selected teacher in this study provided a unique situation where he was in his first semester of professional development using the Science Writing Heuristic Approach to argument-based inquiry with 19 students who had two prior years' experience in ABI. Multiple sources of data were collected, including classroom video with transcripts, teacher interview, researcher field notes, student journals, teacher lesson plans from previous years, and a student questionnaire. Data analysis used a basic qualitative approach. The results showed (1) only the first time period had a true big idea, while the other two units contained topics, (2) each semester contained a similar use for the given big idea, though its role in the class was reduced after the opening activity, (3) the types of teacher questions shifted toward students explaining their comprehension of ideas and more students were involved in discussing each idea and for more turns of talk than in earlier time periods, (4) understanding science term definitions became more prominent later in the semester, with more stating science terms occurring earlier in the semester, (5) no significant changes were seen to the use of argument or claims and evidence throughout the study. The findings have informed theory and practice about science argumentation, the practice of whole-class dialogue, and the understanding of practice along four aspects: (1) apparent lack of understanding about big ideas and how to utilize them as the central organizing feature of a unit, (2) independent development of dialogue and argument, (3) apparent lack of understanding about the structure of argument and use of basic terminology with argument and big ideas, (4) challenges of ABI implementation. This study provides insight into the importance of prolonged and persistent professional development with ABI in teaching practice.

Investigation into the efficiency of different bionic algorithm combinations for a COBRA meta-heuristic

NASA Astrophysics Data System (ADS)

Akhmedova, Sh; Semenkin, E.

2017-02-01

Previously, a meta-heuristic approach, called Co-Operation of Biology-Related Algorithms or COBRA, for solving real-parameter optimization problems was introduced and described. COBRA’s basic idea consists of a cooperative work of five well-known bionic algorithms such as Particle Swarm Optimization, the Wolf Pack Search, the Firefly Algorithm, the Cuckoo Search Algorithm and the Bat Algorithm, which were chosen due to the similarity of their schemes. The performance of this meta-heuristic was evaluated on a set of test functions and its workability was demonstrated. Thus it was established that the idea of the algorithms’ cooperative work is useful. However, it is unclear which bionic algorithms should be included in this cooperation and how many of them. Therefore, the five above-listed algorithms and additionally the Fish School Search algorithm were used for the development of five different modifications of COBRA by varying the number of component-algorithms. These modifications were tested on the same set of functions and the best of them was found. Ways of further improving the COBRA algorithm are then discussed.

Concept confusion and concept discernment in basic magnetism using analogical reasoning

NASA Astrophysics Data System (ADS)

Lemmer, Miriam; Nicodimus Morabe, Olebogeng

2017-07-01

Analogical reasoning is central to all learning, whether in daily life situations, in the classroom or while doing research. Although analogies can aid the learning process of making sense of phenomena and understanding new ideas in terms of known ideas, these should be used with care. This article reports a study of the use of analogies and the consequences of this use in the teaching of magnetism with special reference to misconceptions. We begin by identifying concept confusion and associated misconceptions in magnetism due to in-service physics teachers’ spontaneous analogical reasoning. Two analogy-based experiments that can be used to convert such concept confusion to discernment are then described. These experiments focus on understanding basic principles about sources and interactions of magnetic fields and implement the constructivist learning processes of discrimination and generalization. Lastly, recommendations towards reinforcement of conceptual understanding of basic magnetism in its relation to electricity are proposed.

Odor source identification by grounding linguistic descriptions in an artificial nose

NASA Astrophysics Data System (ADS)

Loutfi, Amy; Coradeschi, Silvia; Duckett, Tom; Wide, Peter

2001-03-01

This paper addresses the problem of enabling autonomous agents (e.g., robots) to carry out human oriented tasks using an electronic nose. The nose consists of a combination of passive gas sensors with different selectivity, the outputs of which are fused together with an artificial neural network in order to recognize various human-determined odors. The basic idea is to ground human-provided linguistic descriptions of these odors in the actual sensory perceptions of the nose through a process of supervised learning. Analogous to the human nose, the paper explains a method by which an electronic nose can be used for substance identification. First, the receptors of the nose are exposed to a substance by means of inhalation with an electric pump. Then a chemical reaction takes place in the gas sensors over a period of time and an artificial neural network processes the resulting sensor patterns. This network was trained to recognize a basic set of pure substances such as vanilla, lavender and yogurt under controlled laboratory conditions. The complete system was then validated through a series of experiments on various combinations of the basic substances. First, we showed that the nose was able to consistently recognize unseen samples of the same substances on which it had been trained. In addition, we presented some first results where the nose was tested on novel combinations of substances on which it had not been trained by combining the learned descriptions - for example, it could distinguish lavender yogurt as a combination of lavender and yogurt.

The Legal Ethical Backbone of Conscientious Refusal.

PubMed

Munthe, Christian; Nielsen, Morten Ebbe Juul

2017-01-01

This article analyzes the idea of a legal right to conscientious refusal for healthcare professionals from a basic legal ethical standpoint, using refusal to perform tasks related to legal abortion (in cases of voluntary employment) as a case in point. The idea of a legal right to conscientious refusal is distinguished from ideas regarding moral rights or reasons related to conscientious refusal, and none of the latter are found to support the notion of a legal right. Reasons for allowing some sort of room for conscientious refusal for healthcare professionals based on the importance of cultural identity and the fostering of a critical atmosphere might provide some support, if no countervailing factors apply. One such factor is that a legal right to healthcare professionals' conscientious refusal must comply with basic legal ethical tenets regarding the rule of law and equal treatment, and this requirement is found to create serious problems for those wishing to defend the idea under consideration. We conclude that the notion of a legal right to conscientious refusal for any profession is either fundamentally incompatible with elementary legal ethical requirements, or implausible because it undermines the functioning of a related professional sector (healthcare) or even of society as a whole.

Beginning to Teach Chemistry: How personal and academic characteristics of pre-service science teachers compare with their understandings of basic chemical ideas

NASA Astrophysics Data System (ADS)

Kind, Vanessa; Morten Kind, Per

2011-10-01

Around 150 pre-service science teachers (PSTs) participated in a study comparing academic and personal characteristics with their misconceptions about basic chemical ideas taught to 11-16-year-olds, such as particle theory, change of state, conservation of mass, chemical bonding, mole calculations, and combustion reactions. Data, collected by questionnaire, indicate that despite all PSTs being regarded technically as 'academically well-qualified' for science teaching, biology and physics specialists have more extensive misconceptions than chemists. Two personal characteristics, PSTs' preferences for teaching as a subject 'specialist' or as a 'generalist' teaching all sciences and their self-confidence for working in these two domains, were assessed by responses to Likert-scale statements. Proportionately more biologists tend to be 'super-confident' generalists, while more physicists were specialists anxious about outside specialism teaching. No statistically significant relationships between personal characteristics and misconceptions were found, suggesting that chemistry may be being taught by confident PSTs with poor understandings of basic ideas. Furthermore, these data suggest that attending to PSTs' personal characteristics alongside other components of a teacher's professional knowledge base may contribute to creating more effective science teachers. The paper presents a novel way of considering PSTs' qualities for teaching that offers potential for further research and initial teacher training course development.

The ontogeny of an idea: John Bowlby and contemporaries on mother-child separation.

PubMed

van der Horst, Frank C P; van der Veer, Renée

2010-02-01

In this contribution, the authors situate the development of Bowlby's attachment theory against the background of the social, cultural, and scientific developments in interbellum Britain. It is shown that fairly early in his life Bowlby adopted one fundamental idea-that an infant primarily needs a warm and loving mother, and that separations from the mother are potentially damaging-and never substantially changed that basic notion in later years. Bowlby's first and foremost goal-and his lifelong undertaking-was to convince certain others (e.g., orthodox psychoanalysts, psychiatrists, clinicians, and medical doctors) of the importance of this idea by theorizing and gathering empirical evidence. Bowlby's view of mother love deprivation as the main source of maladjusted behavior was at variance with the views of many practitioners and theorists, but it was by no means fully novel and original. The authors show that Bowlby took inspiration from various persons and groups in British society with whom he shared basically similar views.

Towards physics of neural processes and behavior

PubMed Central

Latash, Mark L.

2016-01-01

Behavior of biological systems is based on basic physical laws, common across inanimate and living systems, and currently unknown physical laws that are specific for living systems. Living systems are able to unite basic laws of physics into chains and clusters leading to new stable and pervasive relations among variables (new physical laws) involving new parameters and to modify these parameters in a purposeful way. Examples of such laws are presented starting from the tonic stretch reflex. Further, the idea of control with referent coordinates is formulated and merged with the idea of hierarchical control and the principle of abundance. The notion of controlled stability of behaviors is linked to the idea of structured variability, which is a common feature across living systems and actions. The explanatory and predictive power of this approach is illustrated with respect to the control of both intentional and unintentional movements, the phenomena of equifinality and its violations, preparation to quick actions, development of motor skills, changes with aging and neurological disorders, and perception.

Evaluation of Semi-supervised Learning for Classification of Protein Crystallization Imagery.

PubMed

Sigdel, Madhav; Dinç, İmren; Dinç, Semih; Sigdel, Madhu S; Pusey, Marc L; Aygün, Ramazan S

2014-03-01

In this paper, we investigate the performance of two wrapper methods for semi-supervised learning algorithms for classification of protein crystallization images with limited labeled images. Firstly, we evaluate the performance of semi-supervised approach using self-training with naïve Bayesian (NB) and sequential minimum optimization (SMO) as the base classifiers. The confidence values returned by these classifiers are used to select high confident predictions to be used for self-training. Secondly, we analyze the performance of Yet Another Two Stage Idea (YATSI) semi-supervised learning using NB, SMO, multilayer perceptron (MLP), J48 and random forest (RF) classifiers. These results are compared with the basic supervised learning using the same training sets. We perform our experiments on a dataset consisting of 2250 protein crystallization images for different proportions of training and test data. Our results indicate that NB and SMO using both self-training and YATSI semi-supervised approaches improve accuracies with respect to supervised learning. On the other hand, MLP, J48 and RF perform better using basic supervised learning. Overall, random forest classifier yields the best accuracy with supervised learning for our dataset.

Portable implementation model for CFD simulations. Application to hybrid CPU/GPU supercomputers

NASA Astrophysics Data System (ADS)

Oyarzun, Guillermo; Borrell, Ricard; Gorobets, Andrey; Oliva, Assensi

2017-10-01

Nowadays, high performance computing (HPC) systems experience a disruptive moment with a variety of novel architectures and frameworks, without any clarity of which one is going to prevail. In this context, the portability of codes across different architectures is of major importance. This paper presents a portable implementation model based on an algebraic operational approach for direct numerical simulation (DNS) and large eddy simulation (LES) of incompressible turbulent flows using unstructured hybrid meshes. The strategy proposed consists in representing the whole time-integration algorithm using only three basic algebraic operations: sparse matrix-vector product, a linear combination of vectors and dot product. The main idea is based on decomposing the nonlinear operators into a concatenation of two SpMV operations. This provides high modularity and portability. An exhaustive analysis of the proposed implementation for hybrid CPU/GPU supercomputers has been conducted with tests using up to 128 GPUs. The main objective consists in understanding the challenges of implementing CFD codes on new architectures.

Is the Quilted Multiverse Consistent with a Thermodynamic Arrow of Time?

NASA Astrophysics Data System (ADS)

Aharonov, Yakir; Cohen, Eliahu; Shushi, Tomer

2018-02-01

Theoretical achievements, as well as much controversy, surround multiverse theory. Various types of multiverses, with an increasing amount of complexity, were suggested and thoroughly discussed in literature by now. While these types are very different, they all share the same basic idea: our physical reality consists of more than just one universe. Each universe within a possibly huge multiverse might be slightly or even very different from the others. The quilted multiverse is one of these types, whose uniqueness arises from the postulate that every possible event will occur infinitely many times in infinitely many universes. In this paper we show that the quilted multiverse is not self-consistent due to the instability of entropy decrease under small perturbations. We therefore propose a modified version of the quilted multiverse which might overcome this shortcoming. It includes only those universes where the minimal entropy occurs at the same instant of (cosmological) time. Only these universes whose initial conditions are fine-tuned within a small phase-space region would evolve consistently to form their "close"' states at present. A final boundary condition on the multiverse may further lower the amount of possible, consistent universes. Finally, some related observations regarding the many-worlds interpretation of quantum mechanics and the emergence of classicality are discussed.

"Energy ideas" run through much of secondary school biology teaching. These ideas are not always consistent with each other or with the ideas used by other science disciplines. Would a change in terminology help avoid confusion or do we need to review the use of "energy" in science teaching?

Towards physics of neural processes and behavior.

PubMed

Latash, Mark L

2016-10-01

Behavior of biological systems is based on basic physical laws, common across inanimate and living systems, and currently unknown physical laws that are specific for living systems. Living systems are able to unite basic laws of physics into chains and clusters leading to new stable and pervasive relations among variables (new physical laws) involving new parameters and to modify these parameters in a purposeful way. Examples of such laws are presented starting from the tonic stretch reflex. Further, the idea of control with referent coordinates is formulated and merged with the idea of hierarchical control and the principle of abundance. The notion of controlled stability of behaviors is linked to the idea of structured variability, which is a common feature across living systems and actions. The explanatory and predictive power of this approach is illustrated with respect to the control of both intentional and unintentional movements, the phenomena of equifinality and its violations, preparation to quick actions, development of motor skills, changes with aging and neurological disorders, and perception.

The Tao of Microelectronics

NASA Astrophysics Data System (ADS)

Zhang, Yumin

2014-12-01

Microelectronics is a challenging course to many undergraduate students and is often described as very messy. Before taking this course, all the students have learned circuit analysis, where basically all the problems can be solved by applying Kirchhoff's laws. In addition, most engineering students have also learned engineering mechanics: statics and dynamics, where Newton's laws and related principles can be applied in solving all the problems. However, microelectronics is not as clean as these courses. There are hundreds of equations for different circuits, and it is impossible to remember which equation should be applied to which circuit. One of the common pitfalls in learning this course is over-focusing at the equation level and ignoring the ideas (Tao) behind it. Unfortunately, these ideas are not summarized and emphasized in most microelectronics textbooks, though they cover various electronic circuits comprehensively. Therefore, most undergraduate students feel at a loss when they start to learn this topic. This book tries to illustrate the major ideas and the basic analysis techniques, so that students can derive the right equations easily when facing an electronic circuit.

Drug policy, harm and human rights: a rationalist approach.

PubMed

Stevens, Alex

2011-05-01

It has recently been argued that drug-related harms cannot be compared, so making it impossible to choose rationally between various drug policy options. Attempts to apply international human rights law to this area are valid, but have found it difficult to overcome the problems in applying codified human rights to issues of drug policy. This article applies the rationalist ethical argument of Gewirth (1978) to this issue. It outlines his argument to the 'principle of generic consistency' and the hierarchy of basic, nonsubtractive and additive rights that it entails. It then applies these ideas to drug policy issues, such as whether there is a right to use drugs, whether the rights of drug 'addicts' can be limited, and how different harms can be compared in choosing between policies. There is an additive right to use drugs, but only insofar as this right does not conflict with the basic and nonsubtractive rights of others. People whose freedom to choose whether to use drugs is compromised by compulsion have a right to receive treatment. They retain enforceable duties not to inflict harms on others. Policies which reduce harms to basic and nonsubtractive rights should be pursued, even if they lead to harms to additive rights. There exists a sound, rational, extra-legal basis for the discussion of drug policy and related harms which enables commensurable discussion of drug policy options. Copyright © 2011 Elsevier B.V.

Big Questions: The Ultimate Building Blocks of Matter

2018-01-16

The Standard Model of particle physics treats quarks and leptons as having no size at all. Quarks are found inside protons and neutrons and the most familiar lepton is the electron. While the best measurements to date support that idea, there is circumstantial evidence that suggests that perhaps the these tiny particles might be composed of even smaller building blocks. This video explains this circumstantial evidence and introduces some very basic ideas of what those building blocks might be.

Austerity and geometric structure of field theories

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kheyfets, A.

The relation between the austerity idea and the geometric structure of the three basic field theories - electrodynamics, Yang-Mills theory, and general relativity - is studied. One of the most significant manifestations of the austerity idea in field theories is thought to be expressed by the boundary of a boundary principle (BBP). The BBP says that almost all content of the field theories can be deduced from the topological identity of delta dot produced with delta = 0 used twice, at the 1-2-3-dimensional level (providing the homogeneous field equations), and at the 2-3-4-dimensional level (providing the conservation laws for themore » source currents). There are some difficulties in this line of thought due to the apparent lack of universality in application of the BBP to the three basic modern field theories above. This dissertation: (a) analyzes the difficulties by means of algebraic topology, integration theory, and modern differential geometry based on the concepts of principal bundles and Ehresmann connections: (b) extends the BBP to the unified Kaluza-Klein theory; (c) reformulates the inhomogeneous field equations and the BBP in terms of E. Cartan moment of rotation, in the way universal for the three theories and compatible with the original austerity idea; and (d) underlines the important role of the soldering structure on spacetime, and indicates that the future development of the austerity idea would involve the generalized theories.« less

Riddles of masculinity: gender, bisexuality, and thirdness.

PubMed

Fogel, Gerald I

2006-01-01

Clinical examples are used to illuminate several riddles of masculinity-ambiguities, enigmas, and paradoxes in relation to gender, bisexuality, and thirdness-frequently seen in male patients. Basic psychoanalytic assumptions about male psychology are examined in the light of advances in female psychology, using ideas from feminist and gender studies as well as important and now widely accepted trends in contemporary psychoanalytic theory. By reexamining basic assumptions about heterosexual men, as has been done with ideas concerning women and homosexual men, complexity and nuance come to the fore to aid the clinician in treating the complex characterological pictures seen in men today. In a context of rapid historical and theoretical change, the use of persistent gender stereotypes and unnecessarily limiting theoretical formulations, though often unintended, may mask subtle countertransference and theoretical blind spots, and limit optimal clinical effectiveness.

Scientific cousins: the relationship between Charles Darwin and Francis Galton.

PubMed

Fancher, Raymond E

2009-01-01

This article traces the personal as well as the intellectual and scientific relationship between Charles Darwin and his younger half-cousin Francis Galton. Although they had been on friendly terms as young men, and Darwin had in some ways been a role model for Galton, the two did not share major scientific interests until after the publication of Darwin's On the Origin of Species in 1859. That work precipitated a religious and philosophical crisis in Galton, which he gradually resolved after conceiving and developing the basic ideas of "hereditary genius" and eugenics. More mathematically inclined than Darwin, he subsequently contributed to the Darwinian evolutionary discussion, and to the future science of psychology, by proposing the basic concept of the nature-nurture dichotomy, the conceptual and statistical foundations for behavior genetics, and the idea for intelligence testing. 2009 APA, all rights reserved

Bead-bead interaction parameters in dissipative particle dynamics: Relation to bead-size, solubility parameter, and surface tension

NASA Astrophysics Data System (ADS)

Maiti, Amitesh; McGrother, Simon

2004-01-01

Dissipative particle dynamics (DPD) is a mesoscale modeling method for simulating equilibrium and dynamical properties of polymers in solution. The basic idea has been around for several decades in the form of bead-spring models. A few years ago, Groot and Warren [J. Chem. Phys. 107, 4423 (1997)] established an important link between DPD and the Flory-Huggins χ-parameter theory for polymer solutions. We revisit the Groot-Warren theory and investigate the DPD interaction parameters as a function of bead size. In particular, we show a consistent scheme of computing the interfacial tension in a segregated binary mixture. Results for three systems chosen for illustration are in excellent agreement with experimental results. This opens the door for determining DPD interactions using interfacial tension as a fitting parameter.

2015-01-01

In this paper, we investigate the performance of two wrapper methods for semi-supervised learning algorithms for classification of protein crystallization images with limited labeled images. Firstly, we evaluate the performance of semi-supervised approach using self-training with naïve Bayesian (NB) and sequential minimum optimization (SMO) as the base classifiers. The confidence values returned by these classifiers are used to select high confident predictions to be used for self-training. Secondly, we analyze the performance of Yet Another Two Stage Idea (YATSI) semi-supervised learning using NB, SMO, multilayer perceptron (MLP), J48 and random forest (RF) classifiers. These results are compared with the basic supervised learning using the same training sets. We perform our experiments on a dataset consisting of 2250 protein crystallization images for different proportions of training and test data. Our results indicate that NB and SMO using both self-training and YATSI semi-supervised approaches improve accuracies with respect to supervised learning. On the other hand, MLP, J48 and RF perform better using basic supervised learning. Overall, random forest classifier yields the best accuracy with supervised learning for our dataset. PMID:25914518

Cerebral localization, including hierarchical organization of the nervous system, was the critical conceptual advance that made possible the development of modern neuroscience in the nineteenth century. Some of our most basic ideas about neural organization were contributed by Hughlings Jackson. In the early twentieth century, Charles Sherrington combined localization with the neurone theory to create the paradigm of neurophysiological integration. Because Sherrington was educated in the Jacksonian tradition of British neurology, Sherringtonian integration contains ideas that are derived from Jackson and from Herbert Spencer.

For physicists who study the basic nature of matter, however, the more important idea is just the opposite.

Application of Local Discretization Methods in the NASA Finite-Volume General Circulation Model

NASA Technical Reports Server (NTRS)

Yeh, Kao-San; Lin, Shian-Jiann; Rood, Richard B.

2002-01-01

We present the basic ideas of the dynamics system of the finite-volume General Circulation Model developed at NASA Goddard Space Flight Center for climate simulations and other applications in meteorology. The dynamics of this model is designed with emphases on conservative and monotonic transport, where the property of Lagrangian conservation is used to maintain the physical consistency of the computational fluid for long-term simulations. As the model benefits from the noise-free solutions of monotonic finite-volume transport schemes, the property of Lagrangian conservation also partly compensates the accuracy of transport for the diffusion effects due to the treatment of monotonicity. By faithfully maintaining the fundamental laws of physics during the computation, this model is able to achieve sufficient accuracy for the global consistency of climate processes. Because the computing algorithms are based on local memory, this model has the advantage of efficiency in parallel computation with distributed memory. Further research is yet desirable to reduce the diffusion effects of monotonic transport for better accuracy, and to mitigate the limitation due to fast-moving gravity waves for better efficiency.

Deriving Laws from Ordering Relations

NASA Technical Reports Server (NTRS)

Knuth, Kevin H.

2004-01-01

The effect of Richard T. Cox's contribution to probability theory was to generalize Boolean implication among logical statements to degrees of implication, which are manipulated using rules derived from consistency with Boolean algebra. These rules are known as the sum rule, the product rule and Bayes Theorem, and the measure resulting from this generalization is probability. In this paper, I will describe how Cox s technique can be further generalized to include other algebras and hence other problems in science and mathematics. The result is a methodology that can be used to generalize an algebra to a calculus by relying on consistency with order theory to derive the laws of the calculus. My goals are to clear up the mysteries as to why the same basic structure found in probability theory appears in other contexts, to better understand the foundations of probability theory, and to extend these ideas to other areas by developing new mathematics and new physics. The relevance of this methodology will be demonstrated using examples from probability theory, number theory, geometry, information theory, and quantum mechanics.

Depression in Taiwanese university students is a significant problem in terms of life and financial costs. The purpose of this study was to examine the impact of four selected personality traits, namely interpersonal problems, ideas of being persecuted, social students in introversion, and self depreciation, on the inclination to be depressed among students in Taiwanese university. A self-report survey was administered to students at a Taiwanese university and consisted of three parts: demographics, the Chinese version of the Basic Personality Inventory (BPI), and the Taiwanese Depression Questionnaire. The level of depression among students was assessed, and the relationships among the various variables were explored using analysis of variance (ANOVA) and regression. Altogether, 255 students successfully completed the survey. Overall, 37.62% of students were suffering from depression, including 4.7% who indicated that they were severely depressed, 18.30% who were moderately depressed, and 14% who were mildly depressed. In a multiple-regression model, ideas of being persecuted and self depreciation were both significant when predicting an inclination to be depressed. Depression is a problem for many university students in Taiwan. Understanding which personality traits are related to depression in Taiwanese students is important for student affair administrators and medical professionals and will help them to prevent and treat this debilitating illness.

Allelic variants of hereditary prions: The bimodularity principle.

Tikhodeyev, Oleg N; Tarasov, Oleg V; Bondarev, Stanislav A

2017-01-02

Modern biology requires modern genetic concepts equally valid for all discovered mechanisms of inheritance, either "canonical" (mediated by DNA sequences) or epigenetic. Applying basic genetic terms such as "gene" and "allele" to protein hereditary factors is one of the necessary steps toward these concepts. The basic idea that different variants of the same prion protein can be considered as alleles has been previously proposed by Chernoff and Tuite. In this paper, the notion of prion allele is further developed. We propose the idea that any prion allele is a bimodular hereditary system that depends on a certain DNA sequence (DNA determinant) and a certain epigenetic mark (epigenetic determinant). Alteration of any of these 2 determinants may lead to establishment of a new prion allele. The bimodularity principle is valid not only for hereditary prions; it seems to be universal for any epigenetic hereditary factor.

Clinical and basic scientists at academic medical and biomedical research institutions often form ideas that could have both monetary and human health benefits if developed and applied to improvement of human wellbeing. However, such ideas lose much of their potential value in both regards if they are disclosed in traditional knowledge-sharing forums such as abstracts, posters, and oral presentations at research meetings. Learning the basics about intellectual property protection and obtaining professional guidance in the management of intellectual property from a knowledgeable technology management professional or intellectual property attorney can avoid such losses yet pose a minimal burden of confidentiality on the investigator. Knowing how to successfully navigate the early stages of intellectual property protection can greatly increase the likelihood that discoveries and knowledge will become available for the public good without diminishing the important mandate of disseminating knowledge through traditional knowledge-sharing forums.

Students received significantly higher comprehension scores using the enhanced version. Furthermore, students preferred the enhanced version and thought it helped them learn the material better.

Austerity and Geometric Structure of Field Theories

NASA Astrophysics Data System (ADS)

Kheyfets, Arkady

The relation between the austerity idea and the geometric structure of the three basic field theories- -electrodynamics, Yang-Mills theory, and general relativity --is studied. The idea of austerity was originally suggested by J. A. Wheeler in an attempt to formulate the laws of physics in such a way that they would come into being only within "the gates of time" extending from big bang to big crunch, rather than exist from everlasting to everlasting. One of the most significant manifestations of the austerity idea in field theories is thought to be expressed by the boundary of a boundary principle (BBP). The BBP says that almost all content of the field theories can be deduced from the topological identity (PAR-DIFF)(CCIRC)(PAR -DIFF) = 0 used twice, at the 1-2-3-dimensional level (providing the homgeneous field equations), and at the 2-3-4-dimensional level (providing the conservation laws for the source currents). There are some difficulties in this line of thought due to the apparent lack of universality in application of the BBP to the three basic modern field theories--electrodynamics, Yang-Mills theory, and general relativity. This dissertation: (a) analyses the difficulties by means of algebraic topology, integration theory and modern differential geometry based on the concepts of principal bundles and Ehresmann connections; (b) extends the BBP to the unified Kaluza-Klein theory; (c) reformulates the inhomogeneous field equations and the BBP in terms of E. Cartan moment of rotation, in the way universal for all the three theories and compatible with the original austerity idea; (d) underlines the important role of the soldering structure on spacetime, and indicates that the future development of the austerity idea would involve the generalized theories, including the soldering form as a dynamical variable rather than as a background structure.

This paper reports on the experimental verification of the ability of IDEA (Intelligent Distributed Execution Architecture) effectively operate at multiple levels of abstraction in an autonomous control system. The basic hypothesis of IDEA is that a large control system can be structured as a collection of interacting control agents, each organized around the same fundamental structure. Two IDEA agents, a system-level agent and a mission-level agent, are designed and implemented to autonomously control the K9 rover in real-time. The system is evaluated in the scenario where the rover must acquire images from a specified set of locations. The IDEA agents are responsible for enabling the rover to achieve its goals while monitoring the execution and safety of the rover and recovering from dangerous states when necessary. Experiments carried out both in simulation and on the physical rover, produced highly promising results.

The enigma of energy: A philosophical inquiry

NASA Astrophysics Data System (ADS)

Todaro-Franceschi, Vidette

1998-06-01

A philosophical inquiry was undertaken to examine the enigma of energy in an attempt to clarify and further illuminate the basic ideas of energy. Beginning with the origin of the concept-Aristotle's conceptualization of energeia-and continuing through to the present day with an overview of the historical conceptual development of energy in Western science, an analysis and interpretation of the scientific and philosophic literature was performed. Literature regarding aspects of human sentience was also examined for underlying ideas of energy. And, finally, selected medical and nursing science theoretical frameworks were analyzed with the hope of further grasping the philosophical underpinnings related to the phenomenon of human energy. Certain ideas of energy became evident. Energy can be viewed as a process and this view works well within the physical science domain. When energy is viewed as a process it falls within the mechanistic tradition: things are viewed as particulate, and cause and effect related. However, energy can also be viewed as a phenomenon, a thing. As a phenomenon, energy is continually transforming and actualizing inherent potentials in a communal process. When energy is recognized as the sole phenomenon responsible for everything in existence, it becomes evident that all is essentially one. In addition, when energy is viewed in this manner it becomes increasingly difficult to deny the purposive character underlying all nature. It is argued that the mystery ultimately leads to something far beyond what we know exists. One of the intuitive feelings of this researcher was that there were at least two different ideas of energy in the sciences of medicine and nursing, which, while different, shared some common elements as well. An examination of Hippocrates', Nightingale's, Selye's, Levine's, and Rogers' ideas, as well as the basic tenets of alternative health care, revealed two distinct worldviews regarding human energy which are congruent with the ideas of energy as process and as a phenomenon. Both ideas, energy as process, and energy as a real entity, originated in Aristotle's work (384-322 BC) and both ways of viewing energy are still prevalent as we approach the 21 st century.

Skeletal myoblasts for heart regeneration and repair: state of the art and perspectives on the mechanisms for functional cardiac benefits.

Until recently, skeletal myoblasts (SkMBs) have been the most widely used cells in basic research and clinical trials of cell based therapy for cardiac repair and regeneration. Although SkMB engraftment into the post-infarcted heart has been consistently found to improve cardiac contractile function, the underlying therapeutic mechanisms remain still a matter of controversy and debate. This is basically because SkMBs do not attain a cardiac-like phenotype once homed into the diseased heart nor they form a contractile tissue functionally coupled with the surrounding viable myocardium. This issue of concern has generated the idea that the cardiotropic action of SkMBs may depend on the release of paracrine factors. However, the paracrine hypothesis still remains ill-defined, particularly concerning the identification of the whole spectrum of cell-derived soluble factors and details on their cardiac effects. In this context, the possibility to genetically engineering SkMBs to potentate their paracrine attitudes appears particularly attractive and is actually raising great expectation. Aim of the present review is not to cover all the aspects of cell-based therapy with SkMBs, as this has been the object of previous exhaustive reviews in this field. Rather, we focused on novel aspects underlying the interactions between SkMBs and the host cardiac tissues which may be relevant for directing the future basic and applied research on SkMB transplantation for post ischemic cardiac dysfunction.

Most assessments of physiology in medical school use multiple choice tests that may not provide information about a student's critical thinking (CT) process. There are limited performance assessments, but high-fidelity patient simulations (HFPS) may be a feasible platform. The purpose of this pilot study was to determine whether a group's CT process could be observed over a series of HFPS. An instrument [Critical Thinking Skills Rating Instrument CTSRI)] was designed with the IDEAS framework. Fifteen groups of students participated in three HFPS that consisted of a basic knowledge quiz and introduction, HFPS session, and debriefing. HFPS were video recorded, and two raters reviewed and scored all HFPS encounters with the CTSRI independently. Interrater analysis suggested good reliability. There was a correlation between basic knowledge scores and three of the six observations on the CTSRI providing support for construct validity. The median CT ratings significantly increased for all observations between the groups' first and last simulation. However, there were still large percentages of video ratings that indicated students needed substantial prompting during the HFPS. The data from this pilot study suggest that it is feasible to observe CT skills in HFPS using the CTSRI. Based on the findings from this study, we strongly recommend that first-year medical students be competent in basic knowledge of the relevant physiology of the HFPS before participating, to minimize the risk of a poor learning experience.

Field Penetration in a Rectangular Box Using Numerical Techniques: An Effort to Obtain Statistical Shielding Effectiveness

NASA Technical Reports Server (NTRS)

Bunting, Charles F.; Yu, Shih-Pin

2006-01-01

This paper emphasizes the application of numerical methods to explore the ideas related to shielding effectiveness from a statistical view. An empty rectangular box is examined using a hybrid modal/moment method. The basic computational method is presented followed by the results for single- and multiple observation points within the over-moded empty structure. The statistics of the field are obtained by using frequency stirring, borrowed from the ideas connected with reverberation chamber techniques, and extends the ideas of shielding effectiveness well into the multiple resonance regions. The study presented in this paper will address the average shielding effectiveness over a broad spatial sample within the enclosure as the frequency is varied.

Systems biology promises to revolutionize medicine, yet human wellbeing is also inherently linked to healthy societies and environments (sustainability). The IDEA Consortium is a systems ecology open science initiative to conduct the basic scientific research needed to build use-oriented simulations (avatars) of entire social-ecological systems. Islands are the most scientifically tractable places for these studies and we begin with one of the best known: Moorea, French Polynesia. The Moorea IDEA will be a sustainability simulator modeling links and feedbacks between climate, environment, biodiversity, and human activities across a coupled marine-terrestrial landscape. As a model system, the resulting knowledge and tools will improve our ability to predict human and natural change on Moorea and elsewhere at scales relevant to management/conservation actions.

Preliminary Consideration of the ADS Research in China

Power supply is a key issue for China's further economic development. To meet the needs of our economic growth in the next century, the part of nuclear energy in the total newly increased power supply must become larger. However, the present nuclear power stations dominated by the PWR in the world are facing some troubles. Recently, a new concept, called ADS (Accelerator Driven Subcritical system), can avoid these troubles and it is recognized as a most prospective power system for fission energy. So during the early time of nuclear power development in our country, it is worthwhile to exploit this novel idea. In this paper, the ADS research program and a proposed verification facility are described. It consists of an 300MeV/3mA low energy accelerator, a swimming pool reactor and some basic research equipment. Beam physics, such as beam halo formation, in the intense-beam accelerator is also discussed.

Emotion improves and impairs early vision.

PubMed

Bocanegra, Bruno R; Zeelenberg, René

2009-06-01

Recent studies indicate that emotion enhances early vision, but the generality of this finding remains unknown. Do the benefits of emotion extend to all basic aspects of vision, or are they limited in scope? Our results show that the brief presentation of a fearful face, compared with a neutral face, enhances sensitivity for the orientation of subsequently presented low-spatial-frequency stimuli, but diminishes orientation sensitivity for high-spatial-frequency stimuli. This is the first demonstration that emotion not only improves but also impairs low-level vision. The selective low-spatial-frequency benefits are consistent with the idea that emotion enhances magnocellular processing. Additionally, we suggest that the high-spatial-frequency deficits are due to inhibitory interactions between magnocellular and parvocellular pathways. Our results suggest an emotion-induced trade-off in visual processing, rather than a general improvement. This trade-off may benefit perceptual dimensions that are relevant for survival at the expense of those that are less relevant.

The advent of solid-state polymer electrolytes for application in lithium batteries took place more than four decades ago when the ability of polyethylene oxide (PEO) to dissolve suitable lithium salts was demonstrated. Since then, many modifications of this basic system have been proposed and tested, involving the addition of conventional, carbonate-based electrolytes, low molecular weight polymers, ceramic fillers, and others. This Review focuses on ternary polymer electrolytes, that is, ion-conducting systems consisting of a polymer incorporating two salts, one bearing the lithium cation and the other introducing additional anions capable of plasticizing the polymer chains. Assessing the state of the research field of solid-state, ternary polymer electrolytes, while giving background on the whole field of polymer electrolytes, this Review is expected to stimulate new thoughts and ideas on the challenges and opportunities of lithium-metal batteries. © 2016 WILEY-VCH Verlag GmbH & Co.

Neural evidence that human emotions share core affective properties.

Wilson-Mendenhall, Christine D; Barrett, Lisa Feldman; Barsalou, Lawrence W

2013-06-01

Research on the "emotional brain" remains centered around the idea that emotions like fear, happiness, and sadness result from specialized and distinct neural circuitry. Accumulating behavioral and physiological evidence suggests, instead, that emotions are grounded in core affect--a person's fluctuating level of pleasant or unpleasant arousal. A neuroimaging study revealed that participants' subjective ratings of valence (i.e., pleasure/displeasure) and of arousal evoked by various fear, happiness, and sadness experiences correlated with neural activity in specific brain regions (orbitofrontal cortex and amygdala, respectively). We observed these correlations across diverse instances within each emotion category, as well as across instances from all three categories. Consistent with a psychological construction approach to emotion, the results suggest that neural circuitry realizes more basic processes across discrete emotions. The implicated brain regions regulate the body to deal with the world, producing the affective changes at the core of emotions and many other psychological phenomena.

Calcium phosphates represent the largest group of biominerals in vertebrate animals. They also have many uses in industry, agriculture, medicine and everyday life. The calcium phosphates containing the ionic species HPO4(2-) and PO4(3-) are biologically relevant. In medicine, calcium phosphates have been used for bone regeneration for several decades. The requirement of a mouldable, self-setting material has been fulfilled since the mid-1980s because of the development of calcium phosphate cements. Basically, they consist of a powder (e. g. di-, tri- or tetra-calcium phosphates) that is mixed with a liquid. Their properties depend on kind, amount, and location of each atom within the crystal structure. In dentistry calcium phosphate cements play a secondary role at the moment, although they often have an excellent biocompatibility. This review gives a general idea on development and chemistry of calcium phosphate cements and presents different cement types tested in vitro and in vivo.

The unitary plan wind tunnel (UPWT) uses in daily operation are shown. New ideas for improving the quality of established flow visualization methods are developed and programs on promising new flow visualization techniques are pursued. The unitary plan wind tunnel is a supersonic facility, referred to as a production facility, although the majority of tests are inhouse basic research investigations. The facility has two 4 ft. by 4 ft. test sections which span a Mach range from 1.5 to 4.6. The cost of operation is about $10 per minute. Problems are the time required for a flow visualization test setup and investigation costs and the ability to obtain consistently repeatable results. Examples of sublimation, vapor screen, oil flow, minitufts, schlieren, and shadowgraphs taken in UPWT are presented. All tests in UPWT employ one or more of the flow visualization techniques.

Spaceborne SAR Imaging Algorithm for Coherence Optimized.

Qiu, Zhiwei; Yue, Jianping; Wang, Xueqin; Yue, Shun

2016-01-01

This paper proposes SAR imaging algorithm with largest coherence based on the existing SAR imaging algorithm. The basic idea of SAR imaging algorithm in imaging processing is that output signal can have maximum signal-to-noise ratio (SNR) by using the optimal imaging parameters. Traditional imaging algorithm can acquire the best focusing effect, but would bring the decoherence phenomenon in subsequent interference process. Algorithm proposed in this paper is that SAR echo adopts consistent imaging parameters in focusing processing. Although the SNR of the output signal is reduced slightly, their coherence is ensured greatly, and finally the interferogram with high quality is obtained. In this paper, two scenes of Envisat ASAR data in Zhangbei are employed to conduct experiment for this algorithm. Compared with the interferogram from the traditional algorithm, the results show that this algorithm is more suitable for SAR interferometry (InSAR) research and application.

2018-04-01

In the process of geometric correction of remote sensing image, occasionally, a large number of redundant control points may result in low correction accuracy. In order to solve this problem, a control points filtering algorithm based on RANdom SAmple Consensus (RANSAC) was proposed. The basic idea of the RANSAC algorithm is that using the smallest data set possible to estimate the model parameters and then enlarge this set with consistent data points. In this paper, unlike traditional methods of geometric correction using Ground Control Points (GCPs), the simulation experiments are carried out to correct remote sensing images, which using visible stars as control points. In addition, the accuracy of geometric correction without Star Control Points (SCPs) optimization is also shown. The experimental results show that the SCPs's filtering method based on RANSAC algorithm has a great improvement on the accuracy of remote sensing image correction.

Neuron is the basic unit of the biological neural system. The Hodgkin-Huxley (HH) model is one of the most realistic neuron models on the electrophysiological characteristic description of neuron. Hardware implementation of neuron could provide new research ideas to clinical treatment of spinal cord injury, bionics and artificial intelligence. Based on the HH model neuron and the DSP Builder technology, in the present study, a single HH model neuron hardware implementation was completed in Field Programmable Gate Array (FPGA). The neuron implemented in FPGA was stimulated by different types of current, the action potential response characteristics were analyzed, and the correlation coefficient between numerical simulation result and hardware implementation result were calculated. The results showed that neuronal action potential response of FPGA was highly consistent with numerical simulation result. This work lays the foundation for hardware implementation of neural network.

Conformal Bootstrap in Mellin Space

Gopakumar, Rajesh; Kaviraj, Apratim; Sen, Kallol; Sinha, Aninda

2017-02-01

We propose a new approach towards analytically solving for the dynamical content of conformal field theories (CFTs) using the bootstrap philosophy. This combines the original bootstrap idea of Polyakov with the modern technology of the Mellin representation of CFT amplitudes. We employ exchange Witten diagrams with built-in crossing symmetry as our basic building blocks rather than the conventional conformal blocks in a particular channel. Demanding consistency with the operator product expansion (OPE) implies an infinite set of constraints on operator dimensions and OPE coefficients. We illustrate the power of this method in the ɛ expansion of the Wilson-Fisher fixed point by reproducing anomalous dimensions and, strikingly, obtaining OPE coefficients to higher orders in ɛ than currently available using other analytic techniques (including Feynman diagram calculations). Our results enable us to get a somewhat better agreement between certain observables in the 3D Ising model and the precise numerical values that have been recently obtained.

[Origin and thought on the philosophical ideas of acupuncture in Chinese medicine].

Acupuncture in Chinese medicine has been a treasure in Chinese traditional medicine for thousands of years. It is opposite to many basic theories in modern medicine in dynasties. Different from the cross compatibility and interactions among medical medicines, acupuncture in Chinese medicine has its own consolidation and inherent philosophical ideas. In view of this, how to discuss the philosophical ideas and its development of acupuncture in Chinese medicine becomes of great importance. It is crucial to clearly answer the three theoretical propositions in the development of acupuncture in Chinese medicine. Firstly, the differences in acupuncture should be identified between the ancient time and the modern time. The issues focus on the origin of Huangdi Neijing ( Yellow Emperor's Internal Medicine ) and its philosophical divergence. Secondly, the origin of acupuncture should be identified, whether it is from China or India. Thirdly, the differences in acupuncture should be identified between China and the west, focusing on the explanation and rectification of the interrelationship between the acupuncture in Chinese medicine and the western acupuncture. Hence, the basic features are discussed on the reality of acupuncture in Chinese medicine as well as its diversity. Finally, the proposition is extended on how to holistically grasp the philosophical foundation of acupuncture in Chinese medicine and its future trend.

A Citizen Empowered Online Platform for Communicating Climate Science to the General Public

NASA Astrophysics Data System (ADS)

Bourqui, Michel

2014-05-01

This presentation introduces a project, currently in development, of a new online platform for the interaction between climate scientists and citizen. It consists of an open-access, multi-lingual, and peer-reviewed journal publishing climate articles in non-scientific language. It follows three main long-term objectives. The first objective is to establish an ever-growing, multi-lingual library of climate articles providing a knowledge base on climate sciences accessible for free to everyone. The targeted public includes journalists, teachers, students, local actors (e.g. in politics, economy, agriculture), and any other citizen from around the world with an interest in climate sciences. The second goal is to offer a simple and direct channel for scientists wishing to disseminate their research to the general public. A high standard of climate articles is enforced through: a) requiring that the main author is an active climate scientist, and b) an innovative peer-review process involving scientific and non-scientific referees with distinct roles. The third objective is to engage citizen into the climate science. To this aim, the journal proposes three channels. Firstly, citizens are invited to contribute to the dissemination of climate knowledge to the general public by co-authoring, peer-reviewing or translating articles. Secondly, they are offered the capacity to stimulate scientific enquiry by posting invitations for manuscripts to be written on a citizen-inspired topic. Thirdly, a match-up tool is being developed for scientists to gather non-scientists teams for conducting citizen-involving research projects. This platform is scientist-initiated and is meant to be ruled and managed by the participating individuals themselves (scientists and non-scientists) as an international association. It will be financed through country-varying flat memberships. The project is now starting. The basic ideas are drawn; a prototype internet platform has been developed and is operational. In a first phase, climate scientists (and their friends!) are invited to jump in for free, submit climate articles and help design its development. Once an initial content is in place, the second phase will start consisting in an active promotion campaign to reach at the general public and enroll citizens. In this presentation, I will discuss the basic ideas behind this new online platform, its current state and the plans for the next future.

To report a study conducted to compare the utility of the care dependency scale across four countries. The care dependency scale provides a framework for assessing the needs of institutionalized patients for nursing care. Henderson's components of nursing care have been used to specify the variable aspects of the concept of care dependency and to develop the care dependency scale items. The study used a cross-cultural survey design. Patients were recruited from four different countries: Japan, The Netherlands, Poland and Turkey. In each of the participating countries, basic human needs were assessed by nurses using a translated version of the original Dutch care dependency scale. Psychometric properties in terms of reliability and validity of the care dependency scale have been assessed using Cronbach's alpha, Guttman's lambda-2, inter-item correlation and principal components analysis. Data were collected in 2008 and 2009. High internal consistency values were demonstrated. Principal component analysis confirmed the one-factor model reported in earlier studies. Outcomes confirm Henderson's idea that human needs are fundamental appearing in every patient-nurse relationship, independent of the patient's age, the type of care setting and/or cultural background. The psychometric characteristics of the care dependency scale make this instrument very useful for comparative research across countries. © 2012 Blackwell Publishing Ltd.

Tutorial: Physics and modeling of Hall thrusters

NASA Astrophysics Data System (ADS)

Boeuf, Jean-Pierre

2017-01-01

Hall thrusters are very efficient and competitive electric propulsion devices for satellites and are currently in use in a number of telecommunications and government spacecraft. Their power spans from 100 W to 20 kW, with thrust between a few mN and 1 N and specific impulse values between 1000 and 3000 s. The basic idea of Hall thrusters consists in generating a large local electric field in a plasma by using a transverse magnetic field to reduce the electron conductivity. This electric field can extract positive ions from the plasma and accelerate them to high velocity without extracting grids, providing the thrust. These principles are simple in appearance but the physics of Hall thrusters is very intricate and non-linear because of the complex electron transport across the magnetic field and its coupling with the electric field and the neutral atom density. This paper describes the basic physics of Hall thrusters and gives a (non-exhaustive) summary of the research efforts that have been devoted to the modelling and understanding of these devices in the last 20 years. Although the predictive capabilities of the models are still not sufficient for a full computer aided design of Hall thrusters, significant progress has been made in the qualitative and quantitative understanding of these devices.

Effective Moment Feature Vectors for Protein Domain Structures

PubMed Central

Shi, Jian-Yu; Yiu, Siu-Ming; Zhang, Yan-Ning; Chin, Francis Yuk-Lun

2013-01-01

Imaging processing techniques have been shown to be useful in studying protein domain structures. The idea is to represent the pairwise distances of any two residues of the structure in a 2D distance matrix (DM). Features and/or submatrices are extracted from this DM to represent a domain. Existing approaches, however, may involve a large number of features (100–400) or complicated mathematical operations. Finding fewer but more effective features is always desirable. In this paper, based on some key observations on DMs, we are able to decompose a DM image into four basic binary images, each representing the structural characteristics of a fundamental secondary structure element (SSE) or a motif in the domain. Using the concept of moments in image processing, we further derive 45 structural features based on the four binary images. Together with 4 features extracted from the basic images, we represent the structure of a domain using 49 features. We show that our feature vectors can represent domain structures effectively in terms of the following. (1) We show a higher accuracy for domain classification. (2) We show a clear and consistent distribution of domains using our proposed structural vector space. (3) We are able to cluster the domains according to our moment features and demonstrate a relationship between structural variation and functional diversity. PMID:24391828

Origin of life. The role of experiments, basic beliefs, and social authorities in the controversies about the spontaneous generation of life and the subsequent debates about synthesizing life in the laboratory.

PubMed

Deichmann, Ute

2012-01-01

For centuries the question of the origin of life had focused on the question of the spontaneous generation of life, at least primitive forms of life, from inanimate matter, an idea that had been promoted most prominently by Aristotle. The widespread belief in spontaneous generation, which had been adopted by the Church, too, was finally abandoned at the beginning of the twentieth century, when the question of the origin of life became related to that of the artificial generation of life in the laboratory. This paper examines the role of social authorities, researchers' basic beliefs, crucial experiments, and scientific advance in the controversies about spontaneous generation from the seventeenth to the nineteenth centuries and analyzes the subsequent debates about the synthesis of artificial life in the changing scientific contexts of the nineteenth and early-twentieth centuries. It shows that despite the importance of social authorities, basic beliefs, and crucial experiments scientific advances, especially those in microbiology, were the single most important factor in the stepwise abandoning of the doctrine of spontaneous generation. Research on the origin of life and the artificial synthesis of life became scientifically addressed only when it got rid of the idea of constant smooth transitions between inanimate matter and life and explored possible chemical and physical mechanisms of the specificity of basic molecules and processes of life.

Visual mining business service using pixel bar charts

NASA Astrophysics Data System (ADS)

Hao, Ming C.; Dayal, Umeshwar; Casati, Fabio

2004-06-01

Basic bar charts have been commonly available, but they only show highly aggregated data. Finding the valuable information hidden in the data is essential to the success of business. We describe a new visualization technique called pixel bar charts, which are derived from regular bar charts. The basic idea of a pixel bar chart is to present all data values directly instead of aggregating them into a few data values. Pixel bar charts provide data distribution and exceptions besides aggregated data. The approach is to represent each data item (e.g. a business transaction) by a single pixel in the bar chart. The attribute of each data item is encoded into the pixel color and can be accessed and drilled down to the detail information as needed. Different color mappings are used to represent multiple attributes. This technique has been prototyped in three business service applications-Business Operation Analysis, Sales Analysis, and Service Level Agreement Analysis at Hewlett Packard Laboratories. Our applications show the wide applicability and usefulness of this new idea.

Quantum computation for solving linear systems

NASA Astrophysics Data System (ADS)

Cao, Yudong

Quantum computation is a subject born out of the combination between physics and computer science. It studies how the laws of quantum mechanics can be exploited to perform computations much more efficiently than current computers (termed classical computers as oppose to quantum computers). The thesis starts by introducing ideas from quantum physics and theoretical computer science and based on these ideas, introducing the basic concepts in quantum computing. These introductory discussions are intended for non-specialists to obtain the essential knowledge needed for understanding the new results presented in the subsequent chapters. After introducing the basics of quantum computing, we focus on the recently proposed quantum algorithm for linear systems. The new results include i) special instances of quantum circuits that can be implemented using current experimental resources; ii) detailed quantum algorithms that are suitable for a broader class of linear systems. We show that for some particular problems the quantum algorithm is able to achieve exponential speedup over their classical counterparts.

Efficient Management of Certificate Revocation Lists in Smart Grid Advanced Metering Infrastructure

DOE Office of Scientific and Technical Information (OSTI.GOV)

Cebe, Mumin; Akkaya, Kemal

Advanced Metering Infrastructure (AMI) forms a communication network for the collection of power data from smart meters in Smart Grid. As the communication within an AMI needs to be secure, key management becomes an issue due to overhead and limited resources. While using public-keys eliminate some of the overhead of key management, there is still challenges regarding certificates that store and certify the publickeys. In particular, distribution and storage of certificate revocation list (CRL) is major a challenge due to cost of distribution and storage in AMI networks which typically consist of wireless multi-hop networks. Motivated by the need ofmore » keeping the CRL distribution and storage cost effective and scalable, in this paper, we present a distributed CRL management model utilizing the idea of distributed hash trees (DHTs) from peer-to-peer (P2P) networks. The basic idea is to share the burden of storage of CRLs among all the smart meters by exploiting the meshing capability of the smart meters among each other. Thus, using DHTs not only reduces the space requirements for CRLs but also makes the CRL updates more convenient. We implemented this structure on ns-3 using IEEE 802.11s mesh standard as a model for AMI and demonstrated its superior performance with respect to traditional methods of CRL management through extensive simulations.« less

Similarities and Differences In Ideas Generated by Physics Learners: US College Students Vs. Tibetan Buddhist Monks

NASA Astrophysics Data System (ADS)

Johnson, Andy

2008-10-01

We have used PER-based course materials to teach various physics topics to Tibetan Buddhist monks over the last four years. While listening to the monks' ideas through interpreters, we found some striking similarities with ideas that we hear in our own classrooms in the US. However, the degree of similarity of monks' ideas with those of US students varied with the topic. For example, ideas that emerged in the topic of magnetism were often consistent with western ideas while ideas about color addition were sometimes strikingly different from ideas that American students use. The monks' ways of talking lead us to believe that cultural background partially determines how they think initially about particular physics topics. This poster will give examples of similarities and of differences, and attempt to identify reasons for both.

Parameterizations for ensemble Kalman inversion

NASA Astrophysics Data System (ADS)

Chada, Neil K.; Iglesias, Marco A.; Roininen, Lassi; Stuart, Andrew M.

2018-05-01

The use of ensemble methods to solve inverse problems is attractive because it is a derivative-free methodology which is also well-adapted to parallelization. In its basic iterative form the method produces an ensemble of solutions which lie in the linear span of the initial ensemble. Choice of the parameterization of the unknown field is thus a key component of the success of the method. We demonstrate how both geometric ideas and hierarchical ideas can be used to design effective parameterizations for a number of applied inverse problems arising in electrical impedance tomography, groundwater flow and source inversion. In particular we show how geometric ideas, including the level set method, can be used to reconstruct piecewise continuous fields, and we show how hierarchical methods can be used to learn key parameters in continuous fields, such as length-scales, resulting in improved reconstructions. Geometric and hierarchical ideas are combined in the level set method to find piecewise constant reconstructions with interfaces of unknown topology.

Digital Earth - Young generation's comprehension and ideas

NASA Astrophysics Data System (ADS)

Bandrova, T.; Konecny, M.

2014-02-01

The authors are experienced in working with children and students in the field of early warning and crises management and cartography. All these topics are closely connected to Digital Earth (DE) ideas. On the basis of a questionnaire, the young generation's comprehension of DE concept is clarified. Students from different age groups (from 19 to 36) from different countries and with different social, cultural, economical and political backgrounds are asked to provide definition of DE and describe their basic ideas about meaning, methodology and applications of the concept. The questions aim to discover the young generation's comprehension of DE ideas. They partially cover the newest trends of DE development like social, cultural and environmental issues as well as the styles of new communications (Google Earth, Facebook, LinkedIn, etc.). In order to assure the future development of the DE science, it is important to take into account the young generation's expectations. Some aspects of DE development are considered in the Conclusions.

Nonequilibrium Saturation States and Fractional Kinetic Processes In The Turbulent Magnetotail

NASA Astrophysics Data System (ADS)

Milovanov, A. V.; Zelenyi, L. M.

Magnetotail regions with the considerably stretched and thinned magnetic lobe field offer a fertile playground for studying the fundamental properties of the self-organized turbulent systems. The focus of this report is on the turbulent nonequilibrium satu- ration states (NESS's) of the tail, where the plasma strongly couples with the self- organized magnetic and inductive electric fields. We advocate an unconventional de- scription of the NESS's, which brings together the ideas of fractal geometry, topology of manifolds, and fractional ("strange") kinetics. A self-consistent nonlinear fractional kinetic equation is proposed for the particle dynamics near the marginal NESS. We ar- gue that the inherent variability of the NESS is manifest in the low-frequency fluctu- ation spectrum f-1 often referred to as "flicker noise". The self-consistent plasma distribution function at the NESS is shown to reveal a power-law nonthermal tail (E) E-, where the slope 6 7 depends on the type of the spatiotem- poral correlations in the medium. Basic theoretical predictions are discussed against observations. This study was sponsored by the INTAS project 97-1612 and RFBR grants 00-02-17127 and 00-15-96631.

Measuring quality of IT solutions is a priority in software engineering. Although numerous metrics for measuring object-oriented code already exist, measuring quality of UML models or XML Schemas is still developing. One of the research questions in the overall research leaded by ideas described in this paper is whether we can apply already defined object-oriented design metrics on XML schemas based on predefined mappings. In this paper, basic ideas for mentioned mapping are presented. This mapping is prerequisite for setting the future approach to XML schema quality measuring with object-oriented metrics.

Well-being and fairness in the distribution of scarce health resources.

PubMed

Segev, Re'em

2005-06-01

Based on a general thesis regarding the proper resolution of interpersonal conflicts, this paper suggests a normative framework for the distribution of scarce health resources. The proposed thesis includes two basic ideas. First, individual well-being is the fundamental value. Second, interpersonal conflicts affecting well-being should be resolved in light of several conceptions of fairness, reflecting the independent value of persons and the moral significance of responsibility of individuals for the existence of interpersonal conflicts. These ideas are elaborated in several principles that are applied with respect to the distribution of scarce health resources.

Nursing and justice as a basic human need.

PubMed

Johnstone, Megan-Jane

2011-01-01

This paper explores the idea that justice is a basic human need akin to those famously depicted in Maslow's hierarchy of human needs and, as such, warrants recognition as a core element in representative ideas about nursing. Early nurse theorists positioned the principles and practice of nursing as having their origins in 'universal human needs'. The principle of deriving nursing care from human needs was thought to provide a guide not only for promoting health, but for preventing disease and illness. The nursing profession has had a longstanding commitment to social justice as a core professional value and ideal, obligating nurses to address the social conditions that undermine people's health. The idea of justice as a universal human need per se and its possible relationship to people's health outcomes has, however, not been considered. One reason for this is that justice in nursing discourse has more commonly been associated with law and ethics, and the legal and ethical responsibilities of nurses in relation to individualized patient care and, more recently, changing systems of care to improve health and health outcomes. Although this association is not incorrect, it is incomplete. A key aim of this paper is to redress this oversight and to encourage a broader conceptualization of justice as necessary for human survival, health and development, not merely as a professional value, or legal or ethical principle for guiding human conduct. © 2010 Blackwell Publishing Ltd.

Veritas filia temporis: The origins of the idea of scientific progress.

PubMed

Špelda, Daniel

2016-10-01

The article provides insight into the epistemological and anthropological aspect of the origination of the idea of scientific progress. It focuses on the relationship between individual's limited lifetime and the immensity of nature. The basic assumption is that the idea of scientific progress offers a solution of the epistemological problem stemming from the finding that there is no (teleological) coincidence between human cognitive abilities and the extent of nature. In order to facilitate the understanding of the origin of the idea of scientific progress, I propose distinction between the descriptive and prescriptive concepts of progress. While the descriptive notion of progress expresses the cumulative character of scientific knowledge and the superiority of the present over preceding generations, the prescriptive concept pertains to progressivist epistemology directing scientific research at the future development of knowledge. This article claims that the prevalent concept in Antiquity was the descriptive concept of scientific progress. The prescriptive notion had developed only in ancient astronomy. Early modern science was faced with similar issues as ancient astronomy - mainly the empirical finding related to the inexhaustible character of nature. Consequently to the introduction of the idea of progress, the progress of sciences became a purpose in itself - hence becoming infinite.

An investigation of the concept of balance in children ages 6--9: Logic and protologic identifiable in making mobiles

NASA Astrophysics Data System (ADS)

Chun, Seon

This research was conducted to explore children's construction of protologic (foreshadowing of operations) in the context of experience with balance mobiles in a constructivist setting and to explore the usefulness of making mobiles in promoting children's development of the concept of balance. The statement of the problem is (a) Can constructivist principles of cognitive development be used to understand children's progress in the course of educational activities involving balance? If so, how? What does the progressive construction of notions about balance look like in children's behaviors? and (b) Does children's understanding of balance improve after experimenting with making mobiles? The participants in this study were 10 first grade children and 12 third grade children from a public elementary laboratory school located in Cedar Falls, Iowa. The pretest and posttest used a primary balance scale and a beam balance. Making mobiles was used as the intervention. The research of Piaget, Kamii, and Parrat-Dayan (1974/1980) and Inhelder and Piaget (1955/1958) were used as the basic framework for the pretest and posttest. All interviews and the dialogues during the tests and making mobiles were video-ecorded and transcribed for analysis. Evidence of compensation and reversibility, coherence, coordination, and contradiction were assessed in children's reasoning during intervention activities using operational definitions developed by Jean Piaget. Before the intervention, all children had an idea that weight impacts balance, 13 out of 22 children had the idea that distance from the fulcrum impacts balance, and 6 out of 22 children considered weight and distance at the same time. After the intervention, all children maintained the idea that weight is related to balance but more children, 16 out of 22, had the idea that distance is related to balance; and 6 children among the 16 children considered weight and distance at the same time. Through the three intervention activities, more children showed consistently their belief that the higher side needs more weight to making bars balance and the understanding of the idea that distance is related to make bars balance. Nine children experienced a "Eureka" moment, that is, they had a sudden insight about how to make bars of mobile balance or connected their prior experience to the current situation.

Basic Operational Robotics Instructional System

NASA Technical Reports Server (NTRS)

Todd, Brian Keith; Fischer, James; Falgout, Jane; Schweers, John

2013-01-01

The Basic Operational Robotics Instructional System (BORIS) is a six-degree-of-freedom rotational robotic manipulator system simulation used for training of fundamental robotics concepts, with in-line shoulder, offset elbow, and offset wrist. BORIS is used to provide generic robotics training to aerospace professionals including flight crews, flight controllers, and robotics instructors. It uses forward kinematic and inverse kinematic algorithms to simulate joint and end-effector motion, combined with a multibody dynamics model, moving-object contact model, and X-Windows based graphical user interfaces, coordinated in the Trick Simulation modeling environment. The motivation for development of BORIS was the need for a generic system for basic robotics training. Before BORIS, introductory robotics training was done with either the SRMS (Shuttle Remote Manipulator System) or SSRMS (Space Station Remote Manipulator System) simulations. The unique construction of each of these systems required some specialized training that distracted students from the ideas and goals of the basic robotics instruction.

Basic Religious Beliefs and Personality Traits

PubMed Central

Rajaei, Ali Reza; Sarvarazemy, Ahmad

2012-01-01

Objective Spiritual beliefs can help people find meaning of life, and can also influence their feelings, behaviors and mental health. The present research studied the relationship between basic religious beliefs (Human, Existence and God) and five personality factors: neuroticism, extraversion, openness, agreeableness, conscientiousness. Method One hundred seventy eight students of Islamic Azad University in Torbat-jam were randomly selected and completed the basic religious beliefs and NEO Questionnaires. Results Data showed that basic religious beliefs have a significant negative correlation with neuroticism (r=-0.29),and a significant positive relationship with extraversion(r=0.28),openness(r=0.14),agreeableness (r=0.29),and conscientiousness (r=0.48). Also, the results of the regression analysis showed that basic religious beliefs can anticipate neuroticism, extraversion, agreeableness and conscientiousness, but they cannot anticipate the openness factor significantly. Conclusion The findings of this study demonstrate that basic religious beliefs have a positive relationship with good characteristics that help people resolve the challenges of their lives and identity crisis. Thus, the results of this study support the idea of Religious Cognitive–Emotional Theory that religiosity is correlated with positive personality traits. PMID:22952550

Exploring Persona-Scenarios - Using Storytelling to Create Design Ideas

NASA Astrophysics Data System (ADS)

Madsen, Sabine; Nielsen, Lene

This paper explores the persona-scenario method by investigating how the method can support project participants in generating shared understandings and design ideas. As persona-scenarios are stories we draw on narrative theory to define what a persona-scenario is and which narrative elements it should consist of. Based on an empirical study a key finding is that despite our inherent human ability to construct, tell, and interpret stories it is not easy to write and present a good, coherent, and design-oriented story without methodical support. The paper therefore contributes with guidelines that delineate a) what a design-oriented persona-scenario should consist of (product) and b) how to write it (procedure) in order to generate and validate as many, new, and shared understandings and design ideas as possible (purpose). The purpose of the guidelines is to facilitate the construction of persona-scenarios as good, coherent stories, which make sense to the storytellers and to the audience - and which therefore generate many, new, and shared understandings and design ideas.

Clarification process: Resolution of decision-problem conditions

NASA Technical Reports Server (NTRS)

Dieterly, D. L.

1980-01-01

A model of a general process which occurs in both decisionmaking and problem-solving tasks is presented. It is called the clarification model and is highly dependent on information flow. The model addresses the possible constraints of individual indifferences and experience in achieving success in resolving decision-problem conditions. As indicated, the application of the clarification process model is only necessary for certain classes of the basic decision-problem condition. With less complex decision problem conditions, certain phases of the model may be omitted. The model may be applied across a wide range of decision problem conditions. The model consists of two major components: (1) the five-phase prescriptive sequence (based on previous approaches to both concepts) and (2) the information manipulation function (which draws upon current ideas in the areas of information processing, computer programming, memory, and thinking). The two components are linked together to provide a structure that assists in understanding the process of resolving problems and making decisions.

Co-evolution of upstream waves and accelerated ions at parallel shocks

NASA Astrophysics Data System (ADS)

Fujimoto, M.; Sugiyama, T.

2016-12-01

Shock waves in space plasmas have been considered as the agents for various particle acceleration phenomena. The basic idea behind shock acceleration is that particles are accelerated as they move back-and-forth across a shock front. Detailed studies of ion acceleration at the terrestrial bow shock have been performed, however, the restricted maximum energies attained prevent a straight-forward application of obtained knowledge to more energetic astrophysical situations. Here we show by a large-scale self-consistent particle simulation that the co-evolution of magnetic turbulence and accelerated ion population is the foundation for continuous operation of shock acceleration to ever higher energies. Magnetic turbulence is created by ions reflected back upstream of a parallel shock front. The co-evolution arises because more energetic ions excite waves of longer wavelengths, and because longer wavelength modes are capable of scattering (in the upstream) and reflecting (at the shock front) more energetic ions. Via carefully designed numerical experiments, we show very clearly that this picture is true.

Efficient solution of parabolic equations by Krylov approximation methods

NASA Technical Reports Server (NTRS)

Gallopoulos, E.; Saad, Y.

1990-01-01

Numerical techniques for solving parabolic equations by the method of lines is addressed. The main motivation for the proposed approach is the possibility of exploiting a high degree of parallelism in a simple manner. The basic idea of the method is to approximate the action of the evolution operator on a given state vector by means of a projection process onto a Krylov subspace. Thus, the resulting approximation consists of applying an evolution operator of a very small dimension to a known vector which is, in turn, computed accurately by exploiting well-known rational approximations to the exponential. Because the rational approximation is only applied to a small matrix, the only operations required with the original large matrix are matrix-by-vector multiplications, and as a result the algorithm can easily be parallelized and vectorized. Some relevant approximation and stability issues are discussed. We present some numerical experiments with the method and compare its performance with a few explicit and implicit algorithms.

Equilibrium control of nonlinear verticum-type systems, applied to integrated pest control.

PubMed

Molnár, S; Gámez, M; López, I; Cabello, T

2013-08-01

Linear verticum-type control and observation systems have been introduced for modelling certain industrial systems, consisting of subsystems, vertically connected by certain state variables. Recently the concept of verticum-type observation systems and the corresponding observability condition have been extended by the authors to the nonlinear case. In the present paper the general concept of a nonlinear verticum-type control system is introduced, and a sufficient condition for local controllability to equilibrium is obtained. In addition to a usual linearization, the basic idea is a decomposition of the control of the whole system into the control of the subsystems. Starting from the integrated pest control model of Rafikov and Limeira (2012) and Rafikov et al. (2012), a nonlinear verticum-type model has been set up an equilibrium control is obtained. Furthermore, a corresponding bioeconomical problem is solved minimizing the total cost of integrated pest control (combining chemical control with a biological one).

Comparison of two occurrence risk assessment methods for collapse gully erosion ——A case study in Guangdong province

NASA Astrophysics Data System (ADS)

Sun, K.; Cheng, D. B.; He, J. J.; Zhao, Y. L.

2018-02-01

Collapse gully erosion is a specific type of soil erosion in the red soil region of southern China, and early warning and prevention of the occurrence of collapse gully erosion is very important. Based on the idea of risk assessment, this research, taking Guangdong province as an example, adopt the information acquisition analysis and the logistic regression analysis, to discuss the feasibility for collapse gully erosion risk assessment in regional scale, and compare the applicability of the different risk assessment methods. The results show that in the Guangdong province, the risk degree of collapse gully erosion occurrence is high in northeastern and western area, and relatively low in southwestern and central part. The comparing analysis of the different risk assessment methods on collapse gully also indicated that the risk distribution patterns from the different methods were basically consistent. However, the accuracy of risk map from the information acquisition analysis method was slightly better than that from the logistic regression analysis method.

Composite Fermi surface in the half-filled Landau level with anisotropic electron mass

NASA Astrophysics Data System (ADS)

Ippoliti, Matteo; Geraedts, Scott; Bhatt, Ravindra

We study the problem of interacting electrons in the lowest Landau level at half filling in the quantum Hall regime, when the electron dispersion is given by an anisotropic mass tensor. Based on experimental observations and theoretical arguments, the ground state of the system is expected to consist of composite Fermions filling an elliptical Fermi sea, with the anisotropy of the ellipse determined by the competing effects of the isotropic Coulomb interaction and anisotropic electron mass tensor. We test this idea quantitatively by using a numerical density matrix renormalization group method for quantum Hall systems on an infinitely long cylinder. Singularities in the structure factor allow us to map the Fermi surface of the composite Fermions. We compute the composite Fermi surface anisotropy for several values of the electron mass anisotropy which allow us to deduce the functional dependence of the former on the latter. This research was supported by Department of Energy Office of Basic Energy Sciences through Grant No. DE-SC0002140.

Freedom in nature

NASA Astrophysics Data System (ADS)

Hájíček, P.

2009-09-01

The paper starts with the proposal that the cause of the apparent insolubility of the free-will problem are several popular but strongly metaphysical notions and hypotheses. To reduce the metaphysics, some ideas are borrowed from physics. A concept of event causality is discussed. The importance of Hume’s Principle of Causality is stressed and his Principle of Causation is weakened. The key concept of the paper, the so-called relative freedom, is also suggested by physics. It is a kind of freedom that can be observed everywhere in nature. Turning to biology, incomplete knowledge is defined for all organisms. They cope with the problem by Popper’s trial and error processes. One source of their success is the relative freedom of choice from the basic option ranges: mutations, motions and neural connections. Finally, the conjecture is adopted that communicability can be used as a criterion of consciousness and free will is defined as a conscious version of relative freedom. The resulting notion is logically self-consistent and it describes an observable phenomenon that agrees with our experience.

Drawing on student knowledge in human anatomy and physiology

NASA Astrophysics Data System (ADS)

Slominski, Tara Nicole

Prior to instruction, students may have developed alternative conceptions about the mechanics behind human physiology. To help students re-shape these ideas into correct reasoning, the faulty characteristics reinforcing the alternative conceptions need to made explicit. This study used student-generated drawings to expose alternative conceptions Human Anatomy and Physiology students had prior to instruction on neuron physiology. Specifically, we investigated how students thought about neuron communication across a synapse (n=355) and how neuron activity can be modified (n=311). When asked to depict basic communication between two neurons, at least 80% of students demonstrated incorrect ideas about synaptic transmission. When targeting spatial and temporal summation, only eleven students (3.5%) were able to accurately depict at least one form of summation. In response to both drawing questions, student drawings revealed multiple alternative conceptions that resulted in a deeper analysis and characterization of the wide variation of student ideas.

Hardware for hard-up schools?

NASA Astrophysics Data System (ADS)

St John, Stuart A.

2012-01-01

The purpose of this work was to investigate ways in which everyday computers can be used in schools to fulfil several of the roles of more expensive, specialized laboratory equipment for teaching and learning purposes. The brief adopted was to keep things as straightforward as possible so that any school science department with a few basic tools can copy the ideas presented. The project has so far produced a simple, safe input device to enable use of a computer as an oscilloscope and the conversion of external speakers into a signal generator. They are not without their limitations, but the intention is that they may provide opportunities for hands-on learning in schools where budgets are very limited. Several teaching ideas are outlined, with pointers for further development. It is hoped that interest in the project may generate further application of the ideas to the teaching of high school physics.

Model-based Executive Control through Reactive Planning for Autonomous Rovers

NASA Technical Reports Server (NTRS)

Finzi, Alberto; Ingrand, Felix; Muscettola, Nicola

2004-01-01

This paper reports on the design and implementation of a real-time executive for a mobile rover that uses a model-based, declarative approach. The control system is based on the Intelligent Distributed Execution Architecture (IDEA), an approach to planning and execution that provides a unified representational and computational framework for an autonomous agent. The basic hypothesis of IDEA is that a large control system can be structured as a collection of interacting agents, each with the same fundamental structure. We show that planning and real-time response are compatible if the executive minimizes the size of the planning problem. We detail the implementation of this approach on an exploration rover (Gromit an RWI ATRV Junior at NASA Ames) presenting different IDEA controllers of the same domain and comparing them with more classical approaches. We demonstrate that the approach is scalable to complex coordination of functional modules needed for autonomous navigation and exploration.

The poverty of embodied cognition.

PubMed

Goldinger, Stephen D; Papesh, Megan H; Barnhart, Anthony S; Hansen, Whitney A; Hout, Michael C

2016-08-01

In recent years, there has been rapidly growing interest in embodied cognition, a multifaceted theoretical proposition that (1) cognitive processes are influenced by the body, (2) cognition exists in the service of action, (3) cognition is situated in the environment, and (4) cognition may occur without internal representations. Many proponents view embodied cognition as the next great paradigm shift for cognitive science. In this article, we critically examine the core ideas from embodied cognition, taking a "thought exercise" approach. We first note that the basic principles from embodiment theory are either unacceptably vague (e.g., the premise that perception is influenced by the body) or they offer nothing new (e.g., cognition evolved to optimize survival, emotions affect cognition, perception-action couplings are important). We next suggest that, for the vast majority of classic findings in cognitive science, embodied cognition offers no scientifically valuable insight. In most cases, the theory has no logical connections to the phenomena, other than some trivially true ideas. Beyond classic laboratory findings, embodiment theory is also unable to adequately address the basic experiences of cognitive life.

Contemporary concepts of dissociation.

PubMed

Avdibegović, Esmina

2012-10-01

The concept of dissociation was developed in the late 19th century by Pierre Janet for conditions of "double consciousness" in hypnosis, hysteria, spirit possession and mediumship. He defined dissociation as a deficit in the capacity of integration of two or more different "systems of ideas and functions that constitute personality", and suggested that it can be related to a genetic component, to severe illness and fatigue, and particularly to experiencing adverse, potentially traumatizing events. By the late 20th century, various and often contradictory concepts of dissociation were suggested, which were either insufficient or exceedingly including when compared to the original idea. Currently, dissociation is used to describe a wide range of normal and abnormal phenomena as a process in which behaviour, thoughts and emotions can become separated one from another. A complete presentation of mechanisms involved in dissociation is still unknown. Scientific research on basic processes of dissociation is derived mainly from studies of hypnosis and post-traumatic stress disorder. Given the controversies in modern concepts of dissociation, some researchers and theorists suggest return to the original understanding of dissociation as a basic premise for the further development of the concept of dissociation.

Basic principles of Hasse diagram technique in chemistry.

PubMed

Brüggemann, Rainer; Voigt, Kristina

2008-11-01

Principles of partial order applied to ranking are explained. The Hasse diagram technique (HDT) is the application of partial order theory based on a data matrix. In this paper, HDT is introduced in a stepwise procedure, and some elementary theorems are exemplified. The focus is to show how the multivariate character of a data matrix is realized by HDT and in which cases one should apply other mathematical or statistical methods. Many simple examples illustrate the basic theoretical ideas. Finally, it is shown that HDT is a useful alternative for the evaluation of antifouling agents, which was originally performed by amoeba diagrams.

The foundation of self-esteem.

PubMed Central

Bailey, Joseph A.

2003-01-01

Self-esteem is a simplistic term for varied and complex mental states pertaining to how one views oneself. It takes but little research in the voluminous literature to see the vagueness and inconsistencies in its various definitions. Even more problematic is the uncertainty concerning its foundational components. The importance of having a solid definition and specific ideas about the foundational components of self-esteem is that both pave the way to recognizing its causes; to predicting effects from those causes; and to organizing the trouble-shooting process for locating those philosophical flaws or psychological scars which lead to low self-esteem. The purpose of this paper is to offer a common ground for thinking about self-esteem at its most basic level. In order to distinguish the "basic level" from the rest of the components of self-esteem, let us liken it to a skyscraper building. Here, the focus is on the building's "underground foundation" and the base upon which that foundation rests. The base is a definition that allows for the assessment of the foundation. The underground foundation itself consists of the mental building blocks called self-meaning, self-identity, self-image, and self-concepts. To help illustrate their interactions, a few of the "masks" and "faces" of self-esteem will be mentioned. What is not being addressed is the "above ground structure"--those theories and manifestations dealt with by most mental health specialists. PMID:12793795

Universal sequence map (USM) of arbitrary discrete sequences

PubMed Central

2002-01-01

Background For over a decade the idea of representing biological sequences in a continuous coordinate space has maintained its appeal but not been fully realized. The basic idea is that any sequence of symbols may define trajectories in the continuous space conserving all its statistical properties. Ideally, such a representation would allow scale independent sequence analysis – without the context of fixed memory length. A simple example would consist on being able to infer the homology between two sequences solely by comparing the coordinates of any two homologous units. Results We have successfully identified such an iterative function for bijective mappingψ of discrete sequences into objects of continuous state space that enable scale-independent sequence analysis. The technique, named Universal Sequence Mapping (USM), is applicable to sequences with an arbitrary length and arbitrary number of unique units and generates a representation where map distance estimates sequence similarity. The novel USM procedure is based on earlier work by these and other authors on the properties of Chaos Game Representation (CGR). The latter enables the representation of 4 unit type sequences (like DNA) as an order free Markov Chain transition table. The properties of USM are illustrated with test data and can be verified for other data by using the accompanying web-based tool:http://bioinformatics.musc.edu/~jonas/usm/. Conclusions USM is shown to enable a statistical mechanics approach to sequence analysis. The scale independent representation frees sequence analysis from the need to assume a memory length in the investigation of syntactic rules. PMID:11895567

Examining the progression and consistency of thermal concepts: a cross-age study

NASA Astrophysics Data System (ADS)

Adadan, Emine; Yavuzkaya, Merve Nur

2018-03-01

This cross-sectional study examined how the progression and consistency of students' understanding of thermal concepts in everyday contexts changes across the grade levels. A total of 656 Turkish students from Grade 8 (age 13-14), Grade 10 (age 15-16), and the first year of college (age 19-20) participated in the study. The data were analysed using statistical procedures (descriptive and inferential). Findings indicated a substantial progression in the students' scientific understanding of thermal concepts across grade levels. In addition, the students' alternative conceptions about thermal concepts generally decreased in frequency across grade levels, but certain alternative conceptions were observed in every grade level to a similar extent. Even though the number of students who consistently used scientific ideas increased across grade levels, the number of students who consistently used non-scientific ideas decreased across grade levels. However, the number of students who used scientific and non-scientific ideas inconsistently generally increased as they progressed in the science curriculum. These findings can be associated with either fragmentation or alternative conceptions that result from the gradual enrichment processes students experience when they try to integrate scientific concepts into their conceptual frameworks.

Machine Learning

NASA Astrophysics Data System (ADS)

Hoffmann, Achim; Mahidadia, Ashesh

The purpose of this chapter is to present fundamental ideas and techniques of machine learning suitable for the field of this book, i.e., for automated scientific discovery. The chapter focuses on those symbolic machine learning methods, which produce results that are suitable to be interpreted and understood by humans. This is particularly important in the context of automated scientific discovery as the scientific theories to be produced by machines are usually meant to be interpreted by humans. This chapter contains some of the most influential ideas and concepts in machine learning research to give the reader a basic insight into the field. After the introduction in Sect. 1, general ideas of how learning problems can be framed are given in Sect. 2. The section provides useful perspectives to better understand what learning algorithms actually do. Section 3 presents the Version space model which is an early learning algorithm as well as a conceptual framework, that provides important insight into the general mechanisms behind most learning algorithms. In section 4, a family of learning algorithms, the AQ family for learning classification rules is presented. The AQ family belongs to the early approaches in machine learning. The next, Sect. 5 presents the basic principles of decision tree learners. Decision tree learners belong to the most influential class of inductive learning algorithms today. Finally, a more recent group of learning systems are presented in Sect. 6, which learn relational concepts within the framework of logic programming. This is a particularly interesting group of learning systems since the framework allows also to incorporate background knowledge which may assist in generalisation. Section 7 discusses Association Rules - a technique that comes from the related field of Data mining. Section 8 presents the basic idea of the Naive Bayesian Classifier. While this is a very popular learning technique, the learning result is not well suited for human comprehension as it is essentially a large collection of probability values. In Sect. 9, we present a generic method for improving accuracy of a given learner by generatingmultiple classifiers using variations of the training data. While this works well in most cases, the resulting classifiers have significantly increased complexity and, hence, tend to destroy the human readability of the learning result that a single learner may produce. Section 10 contains a summary, mentions briefly other techniques not discussed in this chapter and presents outlook on the potential of machine learning in the future.

There are deep similarities between Whitehead's idea of the process by which nature unfolds and the ideas of quantum theory. Whitehead says that the world is made of ''actual occasions'', each of which arises from potentialities created by prior actual occasions. These actual occasions are happenings modeled on experiential events, each of which comes into being and then perishes, only to be replaced by a successor. It is these experience-like happenings that are the basic realities of nature, according to Whitehead, not the persisting physical particles that Newtonian physics took be the basic entities. Similarly, Heisenberg says that what ismore » really happening in a quantum process is the emergence of an actual from potentialities created by prior actualities. In the orthodox Copenhagen interpretation of quantum theory the actual things to which the theory refer are increments in ''our knowledge''. These increments are experiential events. The particles of classical physics lose their fundamental status: they dissolve into diffuse clouds of possibilities. At each stage of the unfolding of nature the complete cloud of possibilities acts like the potentiality for the occurrence of a next increment in knowledge, whose occurrence can radically change the cloud of possibilities/potentialities for the still-later increments in knowledge. The fundamental difference between these ideas about nature and the classical ideas that reigned from the time of Newton until this century concerns the status of the experiential aspects of nature. These are things such as thoughts, ideas, feelings, and sensations. They are distinguished from the physical aspects of nature, which are described in terms of quantities explicitly located in tiny regions of space and time. According to the ideas of classical physics the physical world is made up exclusively of things of this latter type, and the unfolding of the physical world is determined by causal connections involving only these things. Thus experiential-type things could be considered to influence the flow of physical events only insofar as they themselves were completely determined by physical things. In other words, experiential-type qualities. insofar as they could affect the flow of physical events, could--within the framework of classical physics--not be free: they must be completely determined by the physical aspects of nature that are, by themselves,sufficient to determine the flow of physical events.« less

2016-11-01

The dementia diagnosis gap in sub-Saharan Africa (SSA) is large, partly because of difficulties in screening for cognitive impairment in the community. As part of the Identification and Intervention for Dementia in Elderly Africans (IDEA) study, we aimed to validate the IDEA cognitive screen in a community-based sample in rural Tanzania METHODS: Study participants were recruited from people who attended screening days held in villages within the rural Hai district of Tanzania. Criterion validity was assessed against the gold standard clinical dementia diagnosis using DSM-IV criteria. Construct validity was assessed against, age, education, sex and grip strength and instrumental activities of daily living (IADLs). Internal consistency and floor and ceiling effects were also examined. During community screening, the IDEA cognitive screen had high criterion validity, with an area under the receiver operating characteristic curve of 0.855 (95% CI 0.794 to 0.915). Higher scores on the screen were significantly correlated with lower age, male sex, having attended school, better grip strength and improved performance in activities of daily living. Factor analysis revealed a single factor with an eigenvalue greater than one, although internal consistency was only moderate (Cronbach's alpha = 0.534). The IDEA cognitive screen had high criterion and construct validity and is suitable for use as a cognitive screening instrument in a community setting in SSA. Only moderate internal consistency may partly reflect the multi-domain nature of dementia as diagnosed clinically. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd.

Hyperbolic Orbits and the Planetary Flylby Anomaly

NASA Technical Reports Server (NTRS)

Wilson, T.L.; Blome, H.J.

2009-01-01

Space probes in the Solar System have experienced unexpected changes in velocity known as the flyby anomaly [1], as well as shifts in acceleration referred to as the Pioneer anomaly [2-4]. In the case of Earth flybys, ESA s Rosetta spacecraft experienced the flyby effect and NASA s Galileo and NEAR satellites did the same, although MESSENGER did not possibly due to a latitudinal property of gravity assists. Measurements indicate that both anomalies exist, and explanations have varied from the unconventional to suggestions that new physics in the form of dark matter might be the cause of both [5]. Although dark matter has been studied for over 30 years, there is as yet no strong experimental evidence supporting it [6]. The existence of dark matter will certainly have a significant impact upon ideas regarding the origin of the Solar System. Hence, the subject is very relevant to planetary science. We will point out here that one of the fundamental problems in science, including planetary physics, is consistency. Using the well-known virial theorem in astrophysics, it will be shown that present-day concepts of orbital mechanics and cosmology are not consistent for reasons having to do with the flyby anomaly. Therefore, the basic solution regarding the anomalies should begin with addressing the inconsistencies first before introducing new physics.

Top-down predictions in the cognitive brain

PubMed Central

Kveraga, Kestutis; Ghuman, Avniel S.; Bar, Moshe

2007-01-01

The human brain is not a passive organ simply waiting to be activated by external stimuli. Instead, it is proposed tat the brain continuously employs memory of past experiences to interpret sensory information and predict the immediately relevant future. This review concentrates on visual recognition as the model system for developing and testing ideas about the role and mechanisms of top-down predictions in the brain. We cover relevant behavioral, computational and neural aspects. These ideas are then extended to other domains. The basic elements of this proposal include analogical mapping, associative representations and the generation of predictions. Connections to a host of cognitive processes will be made and implications to several mental disorders will be proposed. PMID:17923222

The study of the wonderful: the first topographical mapping of vision in the brain.

PubMed

Fishman, Ronald S

2008-12-01

The conception by René Descartes of the human brain, notorious as it is for placing the soul or mind in the pineal gland, had yet within it the basic idea of the brain as a highly organized mechanism with topographical sensory mapping and different functions localized in specific areas. Descartes was directly led to this idea by his appreciation of what the retinal image conceived by Johannes Kepler implied, not only for the nature of vision, but for the operation of the brain in general. The linkage between Kepler and Descartes is not widely appreciated but is one of the best examples of synergism in the history of science.

Farmer Decision-Making for Climate Adaptation

NASA Astrophysics Data System (ADS)

Lubell, M.; Niles, M.; Salerno, J.

2015-12-01

This talk will provide an overview of several studies of how farmers make decisions about climate change adaptation and mitigation. A particular focus will be the "limiting factors hypothesis", which argues that farmers will respond to the climate variables that usually have the largest impact on their crop productivity. For example, the most limiting factor in California is usually water so how climate change affects water will be the largest drive of climate adaptation decisions. This basic idea is drawn from the broader theory of "psychological distance", which argue that human decisions are more attuned to ideas that are psychologically closer in space, time, or other factors. Empirical examples come from California, New Zealand, and Africa.

Investigating Undergraduate Students’ Conceptions of Radiation

NASA Astrophysics Data System (ADS)

Romine, James M.; Buxner, Sanlyn; Impey, Chris; Nieberding, Megan; Antonellis, Jessie C.

2014-11-01

Radiation is an essential topic to the physical sciences yet is often misunderstood by the general public. The last time most people have formal instruction about radiation is as students in high school and this knowledge will be carried into adulthood. Peoples’ conceptions of radiation influence their attitude towards research regarding radiation, radioactivity, and other work where radiation is prevalent. In order to understand students’ ideas about radiation after having left high school, we collected science surveys from nearly 12,000 undergraduates enrolled in introductory science courses over a span of 25 years. This research investigates the relationship between students’ conceptions of radiation and students’ personal beliefs and academic field of study.Our results show that many students in the sample were unable to adequately describe radiation. Responses were typically vague, brief, and emotionally driven. Students’ field of study was found to significantly correlate with their conceptions. Students pursuing STEM majors were 60% more likely to describe radiation as an emission and/or form of energy and cited atomic or radioactive sources of radiation twice as often as non-STEM students. Additionally, students’ personal beliefs also appear to relate to their conceptions of radiation. The most prominent misconception shown was that radiation is a generically harmful substance, which was found to be consistent throughout the duration of the study. In particular, non-science majors in our sample had higher rates of misconceptions, often generalized the idea of radiation into a broad singular topic, and had difficulty properly identifying sources.Generalized ideas of radiation and the inability to properly recognize sources of radiation may contribute to the prevalent misconception that radiation is an inexplicably dangerous substance. A basic understanding of both electromagnetic and particulate radiation and the existence of radiation at various energy levels may substantially deter fear-based generalizations and increase students’ abilities to make rational decisions when encountering various types of radiation in daily life.

2016-01-01

Physicians have traditionally been at the forefront of medical research, bringing clinical questions to the laboratory and returning with ideas for treatment. However, we have anecdotally observed a decline in the popularity of basic science research among trainees. We hypothesized that fewer resident physicians have been pursuing basic science research training over time. We examined records from residents in the Surgeon-Scientist and Clinician-Investigator programs at the University of Toronto (1987-2016). Research by residents was categorized independently by 2 raters as basic science, clinical epidemiology or education-related based on the title of the project, the name of the supervisor and Pubmed searches. The study population was divided into quintiles of time, and the proportion pursuing basic science training in each quintile was calculated. Agreement between the raters was 100%; the categorization of the research topic remained unclear in 9 cases. The proportion of trainees pursuing basic science training dropped by 60% from 1987 to 2016 ( p = 0.005). Significantly fewer residents in the Surgeon-Scientist and Clinician-Investigator Programs at the University of Toronto are pursuing training in the basic sciences as compared with previous years.

Improving health care, Part 4: Concepts for improving any clinical process.

PubMed

Batalden, P B; Mohr, J J; Nelson, E C; Plume, S K

1996-10-01

One promising method for streamlining the generation of "good ideas" is to formulate what are sometimes called change concepts-general notions or approaches to change found useful in developing specific ideas for changes that lead to improvement. For example, in current efforts to reduce health care costs by discounting provider charges, the underlying generic concept is "reducing health care costs," and the specific idea is "discounting provider charges." Short-term gains in health care cost reduction can occur by pursuing discounts. After some time, however, limits to such reduction in costs are experienced. Persevering and continuing to travel down the "discounting provider charges" path is less likely to produce further substantial improvement than returning to the basic concept of "reducing health care costs." An interdisciplinary team aiming to reduce costs while improving quality of care for patients in need of hip joint replacement generated ideas for changing "what's done (process) to get better results." After team members wrote down their improvement ideas, they deduced the underlying change concepts and used them to generate even more ideas for improvement. Such change concepts include reordering the sequence of steps (preadmission physical therapy "certification"), eliminating failures at hand-offs between steps (transfer of information from physician's office to hospital), and eliminating a step (epidural pain control). Learning about making change, encouraging change, managing the change within and across organizations, and learning from the changes tested will characterize the sustainable, thriving health systems of the future.

The influence of Nietzsche on Freud's ideas.

PubMed

Chapman, A H; Chapman-Santana, M

1995-02-01

The striking analogies between the ideas of Freud and Friedrich Nietzsche, whose works were published from one to three decades before those of Freud, have been commented upon, but no previous systematic correlation of the ideas of Nietzsche and Freud has been made. The major works of Nietzsche were read, and each possible analogy to an idea later broached by Freud was correlated by a systematic review of his works. Any references to Nietzsche in Freud's writings and reported conversation were culled. Concepts of Nietzsche which are similar to those of Freud include (a) the concept of the unconscious mind; (b) the idea that repression pushes unacceptable feelings and thoughts into the unconscious and thus makes the individual emotionally more comfortable and effective; (c) the conception that repressed emotions and instinctual drives later are expressed in disguised ways (for example, hostile feelings and ideas may be expressed as altruistic sentiments and acts); (d) the concept of dreams as complex, symbolic "illusions of illusions" and dreaming itself as a cathartic process which has healthy properties; and (e) the suggestion that the projection of hostile, unconscious feelings onto others, who are then perceived as persecutors of the individual, is the basis of paranoid thinking. Some of Freud's basic terms are identical to those used by Nietzsche. Freud repeatedly stated that he had never read Nietzsche. Evidence contradicting this are his references to Nietzsche and his quotations and paraphrases of him, in causal conversation and his now published personal correspondence, as well as in his early and later writings.

Ideas versus labor: what do children value in artistic creation?

PubMed

Li, Vivian; Shaw, Alex; Olson, Kristina R

2013-04-01

As scientists, we primarily award authorship, as well as legal patents, to those who generate ideas, often without formally crediting others who executed the actual experiments. However, little is known about how and when people come to value ideas. Here, we investigate whether young children also value ideas over labor. In Study 1, we found that 4 and 6 year olds preferred pictures containing their ideas to those containing their labor. In Study 2 we rule out an alternative explanation-that children simply favor pictures containing their idiosyncratic preferences-by discovering that 6 year olds, but not 4 year olds chose a picture they mistakenly believed contained their idea, over a picture that contained their idiosyncratic preferences. Consistent with these results, using a third-party design in Study 3, we found that 6 year olds, but not 4 year olds favored a person who only contributed an idea over another who only contributed labor in awarding ownership. Across three studies, these results suggest that by 6 years old, children value ideas over labor. Copyright © 2012 Elsevier B.V. All rights reserved.

An Elementary Introduction to Solar Dynamo Theory

NASA Astrophysics Data System (ADS)

Choudhuri, Arnab Rai

2007-07-01

The cyclically varying magnetic field of the Sun is believed to be produced by the hydromagnetic dynamo process. We first summarize the relevant observational data pertaining to sunspots and solar cycle. Then we review the basic principles of MHD needed to develop the dynamo theory. This is followed by a discussion how bipolar sunspots form due to magnetic buoyancy of flux tubes formed at the base of the solar convection zone. Following this, we come to the heart of dynamo theory. After summarizing the basic ideas of a turbulent dynamo and the basic principles of its mean field formulation, we present the famous dynamo wave solution, which was supposed to provide a model for the solar cycle. Finally we point out how a flux transport dynamo can circumvent some of the difficulties associated with the older dynamo models.

The history of the theory of the circulation of the blood.

PubMed

Rampling, M W

2016-01-01

An obvious candidate for the seminal event in the history of haemorheology is Harvey's presentation of the concept of the circulation of the blood. Prior to this, the ideas concerning the movement of blood were based, in Europe and Middle East, largely on the principles laid down by Galen, and these had been, in effect, dogma for nearly a millennium and a half. These principles were basically that blood is formed in the liver, thence it travels to the bodily organs and is consumed -hence there is one-way flow and no circulation of the blood at all. Harvey's revolutionary idea that blood circulates repeatedly around the cardiovascular system laid the foundation for haemorheology because once that idea was accepted then the fluidity of the blood immediately became potentially of crucial importance - and haemorheology was conceived. In this paper the ideas that preceded Harvey will be presented, i.e. those of Galen, Ibn al-Nafis, Vesalius, Fabricius and Colombo etc. Harvey's awareness of this background, due mainly to time spent in Padua, triggered his many experimental investigations and discoveries. Ultimately, these led to his astonishing insights published in De Mortu Cordis in 1628 which changed the understanding of the cardio-vascular system forever.
