We investigate the age distribution function P(t ,t) in prototypical coarsening processes. Here P(t ,t) is the probability density that in a time interval (0,t) a given site was last crossed by an interface in the coarsening process at time t . We determine P(t ,t) exactly in one dimension for the ~deterministic! two-velocity ballistic annihilation process and the ~stochastic! infinite-state Po...

This letter introduces a hyperspectral denoising algorithm based on spatio-spectral total variation. The denoising problem has been formulated as a mixed noise reduction problem. A general noise model has been considered which accounts for not only Gaussian noise but also sparse noise. Inherent structure of hyperspectral images has been exploited by utilizing 2D-total variation along spatial di...

Usually mathematicians use Hodgkin-Huxley model or FitzHug-Nagumo model to simulate action potentials of skeletal muscle fibers. These models are electrically excitable, but skeletal muscle fibers are stimulated chemically. To investigate skeletal muscle fibers we use a model with six ordinary differential equations. This dynamical system is sensitive to initial value of some variables so it is...

An exploratory, qualitative study with the objective of analyzing repercussions of the supervised curricular internship in the development of the ethical dimension of competency in undergraduate nursing students. Semistructured interviews were performed with 28 students, professors and nurse preceptors of a public institution of higher education in the state of São Paulo, during the period of O...

Recent acceptance that obsessive-compulsive disorder (OCD) represents a heterogeneous phenomenon has underscored the need for dimensional approaches to this disorder. However little is known about the relation between neuropsychological functions and symptom dimensions. The purpose of this study was to identify the cognitive deficits correlated with specific symptom dimensions. Thirteen categor...

During the last two decades, dozens of qualitative representations have been proposed. These representations are motivated by a wide variety of applications of spatial data processing such as Geographical Information System (GIS), robotic navigation, and high level vision. For topological reasoning, the Region Connected Calculus (RCC) is perhaps the best-known formalism. The two algebras, RCC5 ...

This study aims to explain and elaborate a new model for the business environmental hostility in small and medium enterprises in the science and technology park in Kermanshah (Iran). The research method is a mixed method. Content analysis was used in the qualitative part, and a confirmatory factor analysis was used in the quantitative section. In the qualitative section for the environmental ho...

As the number, date and form of the written tests are structured and teacher-oriented, it is considered that it creates fear and anxiety among the students. It has been found necessary and important to form a testing model which will keep the students away from the test anxiety and allow them to learn only about the lesson. For this study, qualitative and quantitative methods have been preferre...
