Gigiane Gindri,Rochele Paz Fonseca
Revista da Sociedade Brasileira de Fonoaudiologia , 2012, DOI: 10.1590/s1516-80342012000300021
Abstract: Os processamentos comunicativos discursivo, léxico-semantico, pragmático-inferencial e/ou prosódico podem apresentar-se deficitários após um acidente vascular cerebral. Esses prejuízos demandam métodos e programas de interven o para uma reabilita o efetiva da comunica o. Neste contexto, o objetivo desta revis o sistemática foi identificar e descrever métodos utilizados para reabilita o neuropsicológica da comunica o de adultos acometidos por les o cerebrovascular, mais especificamente, abordagens sistematizadas de interven o para cada um dos processamentos comunicativos. Foram avaliados resumos publicados nos últimos dez anos na base de dados PubMed, utilizando palavras-chave relacionadas aos construtos reabilita o, acidente vascular cerebral (AVC) e comunica o. Para o construto comunica o foram utilizadas, ainda, palavras específicas dos quatro processamentos comunicativos. Inicialmente, foram encontrados 914 abstracts, dos quais, após exclus o dos repetidos, 460 foram analisados. Os critérios de inclus o de abstracts para análise de seus textos completos foram ser estudo empírico, ter a participa o de pelo menos um indivíduo adulto pós-AVC, tratar de reabilita o da comunica o, apresentar interven o para pelo menos um dos quatro processamentos comunicativos, ter avalia o pré e pós-tratamento, estar escrito em inglês, francês ou português, e ter sido publicado nos últimos dez anos. Apenas quatro artigos empíricos cumpriram tais critérios, sendo conduzidos predominantemente com adultos afásicos ou com aprosódia. Assim, tais achados podem ser considerados surpreendentes e alarmantes frente à escassez de estudos sistemáticos de reabilita o de componentes comunicativos. Ressalta-se a necessidade de descri o detalhada de procedimentos de interven o com objetivos específicos para que estudos possam ser replicados, contribuindo também para a verifica o do efeito do tratamento. Sugere-se que propostas de interven o dos processamentos comunicativos sejam delineadas com bases teóricas e que sejam conduzidos e publicados estudos com este enfoque para verifica o de efeito terapêutico. Discursive, lexical-semantic, pragmatic-inferential and/or prosodic communication processing may be impaired following a cerebrovascular accident. These deficits require intervention methods and programmes for effective communication rehabilitation. Within this context, the aim of this systematic review was to identify and describe methods used for neuropsychological rehabilitation of the communication of adults after a stroke, more specifically, systematic interven

Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.32021
Abstract: The physical nature of inertia is explored. Authors, based on Mach’s principle, offer hypothesis of the induction nature of inertia and theory, which allows extend the principle of relativity to the non-inertial reference systems. The system of differential equations, which eliminates the shortcomings of Newtonian mechanics and Special Theory of Relativity (STR) was composed according to this theory. Row of concrete calculations and explanations are made using the theory. Reason of constancy orbital velocities of galaxies is found out and way of its calculations is shown. Existence of dark matter and the new particles (neutralinos, axons, space vacuum etc.) is prejudiced. Axial deviation of the ray of light in gravitational field is explained and calculated. An example of calculation of the Mercury’s orbital motion is made and complex planets’ trajectories are explained by the action of new field with induction nature. Flat rotation of celestial bodies and shaping of planets’ rings (like the Saturn’s rings) are explained. Indistinguishability of Doppler and Einstein’s effects for terrestrial observer is shown.
Observation of Vortex Lattice Related Anomalies in Polycrystalline YBa2Cu3O7-x Near the Superconducting Transition  [PDF]
S. B. Ota
Journal of Modern Physics (JMP) , 2012, DOI: 10.4236/jmp.2012.310183
Abstract: The d.c. I-V characteristic of polycrystalline YBa2Cu3O7-x high temperature superconductors (HTSC) is measured near the transition temperature (Tc). The Tc was found to be 90 K with a width of 2 K. The voltage was measured at various current values and with reversing the current. A difference in voltage was found for forward and reverse current directions near Tc. The observed directionality of the I-V characteristic can be understood in terms of quantized magnetic flux by the self-field of the current and the proximity junctions in these materials. This can also be understood qualitatively as due to the d-wave superconductivity. The measured dc voltage showed increased noise near Tc which is possibly related to 1/f noise due to the motion of Abrikosov flux lines.
Mach Principle and Post-Einsteinian Relativity Theory  [PDF]
B. S. Sadykov
Journal of Modern Physics (JMP) , 2018, DOI: 10.4236/jmp.2018.91003
Abstract: Inertia is one of the most mysterious forces of nature. Its physical nature is unknown. Accordingly, attempts are made to avoid this “dark force” in one way or another. In Newton’s mechanics and in the special relativity theory, this is done by postulating inertial reference frame, in the general relativity theory by postulating the equivalence principle. Postulates cannot change the laws of nature. One needs to know the latter. Given that the forces of inertia result in non-inertial reference frames only, a hypothesis of the induction nature of inertia has been made. According to this hypothesis, the forces of inertia result as the reaction of a body to external influence. A system of equations explaining the physical nature of inertia and its connection to gravity has been drafted. A group of coordinate conversion has been suggested, which without violating the general covariance of the laws of nature, enables to distinguish one reference frame associated with one body from another system associated with another body, to determine the privileged ones, and to take into consideration their influence on the readings of measurement instruments. A modified mechanics had been created. It takes into consideration the Mach’s principle and enables to cover all systems with the relativity principle. All of the relativistic effects arise from it. The reasons for emergence of new particles, dark matter, dark energy etc. are explained. New effects are predicted.

Abstract: this study aimed at conducting a comparative investigation of the decision-making process of two post-unilateral cva adults as well as verifying the role of hemispheric laterality in the performance of iowa gambling task (igt). one adult with right hemisphere damage (rhd) and another with left hemisphere damage (lhd), both following a subcortical ischemic post-cva. the igt was used to evaluate the decision making. patients had appropriate performance on the igt suggesting a general good ability to make decisions. however, only the patient with lhd presented signs of ascendant learning curve. conclusion: these data indicate that a subcortical lesion independent of the hemisphere may not influence on the igt performance. it is suggested that comparative studies of groups should be conducted in order to compare patients with frontal and non-frontal lesions, helping to characterize the decision-making process in population with unilateral vascular damage.
Weibull-Bayesian Estimation Based on Maximum Ranked Set Sampling with Unequal Samples  [PDF]
B. S. Biradar, B. K. Shivanna
Open Journal of Statistics (OJS) , 2016, DOI: 10.4236/ojs.2016.66083
Abstract: A modification of ranked set sampling (RSS) called maximum ranked set sampling with unequal sample (MRSSU) is considered for the Bayesian estimation of scale parameter α of the Weibull distribution. Under this method, we use Linex loss function, conjugate and Jeffreys prior distributions to derive the Bayesian estimate of α. In order to measure the efficiency of the obtained Bayesian estimates with respect to the Bayesian estimates of simple random sampling (SRS), we compute the bias, mean squared error (MSE) and asymptotic relative efficiency of the obtained Bayesian estimates using simulation. It is shown that the proposed estimates are found to be more efficient than the corresponding one based on SRS.
Probabilistic Analysis of a Robot System with Redundant Safety Units and Common-Cause Failures  [PDF]
B. S. DHILLON, Zhijian LI
Intelligent Information Management (IIM) , 2009, DOI: 10.4236/iim.2009.13022
Abstract: This paper presents reliability and availability analyses of a model representing a system having one robot and n-redundant safety units with common-cause failures. At least k safety units must function successfully for the robot system success. The robot and other failure rates and the partially failed system repair rates are assumed constant and the failed robot-safety system repair time is assumed arbitrarily distributed. Markov and supplementary variable methods were used to perform mathematical analysis of this model. Generalized expressions for state probabilities, system availabilities, reliability, mean time to failure, and variance of time to failure are developed. Plots of some resulting expressions are shown.
