Minimum-time running and swimming: an optimal control approach.  

PubMed

During analysis of the competitor's velocity in a run, strong assumptions are imposed upon the runner's tactic. It is assumed that the competitor uses his/her maximal propulsive force in short-distance events. The runner's velocity is assumed constant in long-distance races. None of these assumptions is satisfied during middle-distance races. In this study, the competitor's velocity, minimizing the time taken to cover the distance, is determined by means of extremization of linear integrals using Green's theorem (Miele's method). The model of the competitor's motion is based on two differential equations: the first one derives from Newton's second law, the second one is the equation for power balance. The theory is illustrated with two examples referring to competitive running and swimming. The minimum-time competitive run can be broken into three phases: -the acceleration, -the cruise with the constant velocity, and -the negative kick at the end of the race. The problem has a similar solution in competitive swimming, however, the acceleration is replaced by the gliding phase. PMID:8849819

On optimal velocity during cycling.  

PubMed

This paper focuses on the solution of two problems related to cycling. One is to determine the velocity as a function of distance which minimizes the cyclist's energy expenditure in covering a given distance in a set time. The other is to determine the velocity as a function of the distance which minimizes time for fixed energy expenditure. To solve these problems, an equation of motion for the cyclist riding over arbitrary terrain is written using Newton's second law. This equation is used to evaluate either energy expenditure or time, and the minimization problems are solved using an optimal control formulation in conjunction with the method of Miele [Optimization Techniques with Applications to Aerospace Systems, pp. 69-98 (1962) Academic Press, New York]. Solutions to both optimal control problems are the same. The solutions are illustrated through two examples. In one example where the relative wind velocity is zero, the optimal cruising velocity is constant regardless of terrain. In the second, where the relative wind velocity fluctuates, the optimal cruising velocity varies. PMID:8132689

An examination of the frequency of invalid forgetting on the Test of Memory Malingering.  

PubMed

The Test of Memory Malingering (TOMM) is the most used performance validity test in neuropsychology, but does not measure response consistency, which is central in the measurement of credible presentation. Gunner, Miele, Lynch, and McCaffrey (2012) developed the Albany Consistency Index (ACI) to address this need. The ACI consistency measurement, however, may penalize examinees, resulting in suboptimal accuracy. The Invalid Forgetting Frequency Index (IFFI), created for the present study, utilizes an algorithm to identify and differentiate learning and inconsistent response patterns across TOMM trials. The purpose of this study was to assess the diagnostic accuracy of the ACI and IFFI against a reference test (Malingered Neurocognitive Dysfunction criteria), and to compare both to the standard TOMM indexes. This retrospective case-control study used 59 forensic cases from an outpatient clinic in Southern Kansas. Results indicated that sensitivity, negative predictive value, and overall accuracy of the IFFI were superior to both the TOMM indexes and ACI. Logistic regression odds ratios were similar for TOMM Trial 2, Retention, and IFFI (1.25, 1.24, 1.25, respectively), with the ACI somewhat lower (1.18). The IFFI had the highest rate of group membership predictions (79.7%). Implications and limitations of the present study are discussed. PMID:24742358

The frequency of allergens implicated in bronchial asthma in different areas of Romania.  

PubMed

The study carried out on 582 asthma patients and 164 healthy controls, ranging in age from 5 to 60 years, dwelling in four different towns ( Sibiu , Media?, Baia Mare, Sighetul Marma tiei ) showed that the most frequently involved antigen in allergic bronchial asthma was house dust (50.3 to 86%), followed by Dermatophagoides pteronissinus and atmospheric fungi, and the most frequently encountered associations were likewise between these allergens, hence the orientation towards a specific hyposensitizing therapy. In these localities with a rich gramineous vegetation there was a high per cent of sensitization to the polen of these plants. Sensitization to woollen hairs has been reported in a high percent in the region of Maramure ? and is linked to its ethnical characteristics. In many cases the patients also exhibited hypersensitiveness to bacteria, associated with environmental allergens, the vicious circle realized by an allergic-infectious mechanism being known. The conclusions of the study on the etiology of bronchial asthma in these geographical areas will be used as a basis for the treatment and its orientation. PMID:6539944

Invisible waves and hidden realms: augmented reality and experimental art  

NASA Astrophysics Data System (ADS)

Augmented reality is way of both altering the visible and revealing the invisible. It offers new opportunities for artistic exploration through virtual interventions in real space. In this paper, the author describes the implementation of two art installations using different AR technologies, one using optical marker tracking on mobile devices and one integrating stereoscopic projections into the physical environment. The first artwork, De Ondas y Abejas (The Waves and the Bees), is based on the widely publicized (but unproven) hypothesis of a link between cellphone radiation and the phenomenon of bee colony collapse disorder. Using an Android tablet, viewers search out small fiducial markers in the shape of electromagnetic waves hidden throughout the gallery, which reveal swarms of bees scattered on the floor. The piece also creates a generative soundscape based on electromagnetic fields. The second artwork, Urban Fauna, is a series of animations in which features of the urban landscape become plants and animals. Surveillance cameras become flocks of birds while miniature cellphone towers, lampposts, and telephone poles grow like small seedlings in time-lapse animation. The animations are presented as small stereoscopic projections, integrated into the physical space of the gallery. These two pieces explore the relationship between nature and technology through the visualization of invisible forces and hidden alternate realities.

Descriptive attributes used in the characterization of stingless bees (Apidae: Meliponini) in rural populations of the Atlantic forest (Misiones-Argentina)  

PubMed Central

Abstract Background Human beings employ a combination of morphological, sensorial, utilitarian, cultural and ecological characters when they identify and classify organisms. Ethnotaxonomy has provided a store of information about the characters cultures employ when they identify and classify a vast diversity of taxonomic groups. Nevertheless, some more research is needed to provide a comparison of the characters employed in the description of taxons, and an analysis of the extent to which those descriptors are represented. Stingless bees constitute a diverse group of social insects that have been widely studied from an ethnobiological perspective due to their utilitarian and cultural importance. The objective of this study is to identify the elements local people consider when characterizing stingless bees, and how important these elements are in the study of local classifications. Methods The methodology used involves semi-structured interviews and trips with the informants to rural areas. Locally known ethnospecies are characterized, descriptive traits and salient criteria used in those characterizations are identified, and the frequency of reference of descriptive traits and salient criteria are estimated. Besides, the descriptive traits used for each ethnospecies are compared, and the contribution of the characterizations as a heuristic strategy in the study of folk classification systems is analyzed. Results The use of 19 biological descriptors (grouped according to 4 salient criteria) and of comparisons among ethnospecies was found. Results suggest the existence of group and specific descriptors. Researchers identified which ethnospecies are considered similar, how less important traits contribute to descriptions, the relation between specific descriptors and ethnospecies, the presence of cognitive prototypes, and the most relevant salient properties from the emic perspective. Conclusions The estimated importance of attributes descriptors allowed us to identify the spectrum of salient properties relevant from the emic perspective to characterize the stingless bees. In this sense, the analysis proposed here is useful to study folk taxonomy in culturally heterogeneous groups or multicultural regions, where the linguistic elements usually employed cannot be applied. Resumen Antecedentes Los seres humanos, al identificar y clasificar a los organismos emplean una combinación de características morfológicas, sensoriales, utilitarias, culturales y ecológicas. Entre los aportes generados desde la etnotaxonomía, se ha obtenido información sobre los caracteres utilizados para identificar y clasificar una gran diversidad de grupos taxonómicos. Sin embargo, aún faltan trabajos donde se comparen los caracteres utilizados en las descripciones de taxones y se analice en qué medida estos descriptores se encuentran representados. Las abejas sin aguijón conforman un diverso grupo de insectos sociales que han sido estudiadas desde la perspectiva etnobiológica, dada su importancia utilitaria y cultural. Los interrogantes que guían este trabajo son ¿Qué elementos tienen en cuenta los pobladores para caracterizar a las abejas sin aguijón? y ¿Qué importancia revisten los mismos en el estudio de las clasificaciones locales? Métodos Se realizaron entrevistas semiestructuradas y recorridos en áreas rurales con los informantes. Se caracterizan a las etnoespecies conocidas localmente; se identifican los atributos descriptores y los criterios emergentes utilizados para dichas caracterizaciones; y se estima la frecuencia de citas de los atributos descriptores y criterios emergentes. Por otra parte, se comparan los atributos descriptores empleados para cada etnoespecie y se analiza el aporte de las caracterizaciones como estrategia heurística en el estudio de los sistemas de clasificación folclóricos. Resultados Se halló el empleo de 19 descriptores biológicos (que fueron agrupados en 4 criterios emergentes) y de comparaciones

Understanding the Structure and Evolution of Nearby Disk Galaxies  

NASA Astrophysics Data System (ADS)

In order to understand the structure and evolution of disk galaxies, we studied the stellar and gaseous components as well as the star formation rate in nearby disk galaxies. We used PS1 medium deep survey images to derive five-band (grizy) surface brightness profiles down to 30 ABmag/arcsec^2 for about 700 galaxies. From these stellar mass and mass-to-light ratio radial profiles are derived. The stellar mass radial profiles tend to bend-up at large radii, this often traces an extended old stellar population. The mass-to-light ratio profiles tend to rise outside the r25 radii. We also find a larger fraction of up-bending surface brightness profiles than Polen & Trujillo (2006). This may be because their sample is biased towards low surface brightness galaxies. We used HIPASS data as well as VLA HI 21cm data to study the gas component and dynamics of disk galaxies. We used the GALEX UV images to study the star formation of a HI-selected star-forming sample of about 400 galaxies, compiling a database of FUV and NUV radial profiles and related parameters. We used this to study the star forming efficiency (SFE, star formation rate per unit area divided by gas surface mass density) of the sample galaxies. We found that the UV based SFE has a tighter relationship with HI mass than an H_alpha based SFE as typically used in previous studies and the UV SFE is flat across wide range of stellar mass. We constructed a simple model to predict the distribution of interstellar medium and star formation rate in an equilibrium disk with constant two-fluid Toomre Q. This model can reproduces the SFE relations we derived.

Numerical modeling on progressive internal deformation in down-built diapirs  

NASA Astrophysics Data System (ADS)

A two-dimensional finite difference code (FDCON) is used to estimate the finite deformation within a down-built diapir. The geometry of the down-built diapir is fixed by using two rigid rectangular overburden units which sink into a source layer of a constant viscosity. Thus, the model refers to diapirs consisting of a source layer feeding a vertical stem, and not to other salt structures (e.g. salt sheets or pillows). With this setup we study the progressive strain in three different deformation regimes within the “salt” material: (I) a squeezed channel-flow deformation regime and (II) a corner-flow deformation regime within the source layer, and (III) a pure channel-flow deformation regime within the stem. We analyze the evolution of finite deformation in each regime individually, progressive strain for particles passing all three regimes, and total 2D finite deformation within the salt layer. Model results show that the material which enters the stem bears inherited strain accumulated from the other two domains. Therefore, finite deformation in the stem differs from the expected channel-flow deformation, due to the deformation accumulated within the source layer. The stem displays a high deformation zone within its center and areas of decreasing progressive strain between its center and its boundaries. High deformation zones within the stem could also be observed within natural diapirs (e.g. Klodowa, Polen). The location and structure of the high deformation zone (e.g. symmetric or asymmetric) could reveal information about different rates of salt supplies from the source layer. Thus, deformation pattern could directly be correlated to the evolution of the diapir.

Self-image and perception of mother and father in psychotic and borderline patients.  

PubMed

Psychotic and borderline patients rated their self-image and their perception of their mother and father using the Structural Analysis of Social Behavior model (SASB). The borderline patients had more negative images of themselves and their parents, especially their fathers, than did the psychotic patients and the normal subjects, while the psychotic patients' ratings did not differ much from those of the normal subjects. The self-image was related to the images of both parents for borderline patients and normal subjects, while for the psychotic patients only the image of the mother was important for the self-image. In addition, the psychotic patients did not differentiate between the poles of control and autonomy in the introjected self-image. It was concluded that borderline patients are characterized by negative attachment, while psychotic patients are characterized by poor separation from the mother and poor differentiation between autonomy and control. The paper also discusses how this may influence the patients' relations to others. Psychotische und Borderline Patienten beurteilten ihr Selbstbild und ihre Wahrnehmung von Mutter und Vater mit Hilfe der strukturalen Analyse sozialen Verhaltens (SASB). Die Borderline Patienten hattten negativere Selbstbilder und Elternbilder (speziell Vaterbilder) als die psychotischen Patienten und gesunde Personen. Die Beurteilungen der psychotischen Patienten unterschieden sich dagegen nicht besonders von jenen Gesunder. Das Selbstbild stand in Beziehung zu beiden Elternbildern bei den Borderline Patienten und den Gesunden, während bei den psychotischen Patienten nur das Mutterbild für das Selbstbild bedeutsam war. Außerdem konnte bei den psychotischen Patienten nicht zwischen den Polen der Kontrolle und Autonomie bzgl. der introjizierten Selbstbilder differenziert werden. Aus den Ergebnissen wird gefolgert, dass Borderline Patienten durch eine negative Bindung charackterisiert sind, psychotische Patienten dagegen durch eine mangelnde Separation von ihren Müttern und eine geringe Differenzierung zwischen Autonomie und Kontrolle. Es wird außerdem diskutiert, wie die Ergebnisse auf die realen Beziehungen der Patienten zu anderen Menschen Einflus nehmen könnten. Des patients psychotiques et Borderline ont évalué leur image d'eux-mêmes et leur perception de leur mère et père à l'aide du modèle de l'Analyse Structural du Comportement Social (SASB. Les patients Borderline avaient des imagess plus négatives d'eux-mêmes et de leurs parents, surtout de leur père, que les patients psychotiques et les sujets normaux, alors que les patients psychotiques se jugeaient à peine différemment des sujets normaux. L'image de soi était en relation avec les images des deux parents pour les patients Borderline et pour les sujets normaux, alors que pour les patients psychotiques, seulement l'image de la mère jouait un rôle pour leur image. En plus, les patients psychotiques ne différenciaient pas entre les pôles de contrôle et d'autonomie dans l'image de soi introjectée. Nous en avons conclu que les patients Borderline se caractérisent par un attachement négatif, et les patients psychotiques par une faible séparation de la mère ainsi qu'une différenciation modeste entre autonomie et contrôle. L'influence de ceci sur les relations des patients avec les autrs est discutée dans cet article. Pacientes limítrofes y psicóticos evaluaron su autoimagen y la percepción que tenían de sus padres usando el modelo de Análisis estructural del comportamiento social (SASB). Los pacientes limítrofes registraron imágenes más negativas de sí mismos y de sus progenitores, especialmente de su padre, que los pacientes psicóticos y los normales, mientras que las evaluaciones de los pacientes psicóticos no difirieron mucho de las de los sujetos normales. La autoimagen tuvo relación con la imagen de ambos progenitores tanto en el caso de los pacientes limítrofes como de los sujetos normales, mientras que para los pacientes psicóticos no diferenciaron entre control y autonomía en la a
