Representation of Refugees, Asylum-Seekers and Refugee Affairs In Hungarian Dailies
Lilla VICSEK,Roland KESZI,Marcell MáRKUS
Journal of Identity and Migration Studies , 2008,
Abstract: How does the press in Hungary write about refugees, asylum-seekers and refugee affairs? We sought to answer this question. Articles appearing in 2005 and 2006 in two leading national Hungarian dailies were examined with quantitative content analysis. The results show that the articles analyzed often treat refugee affairs as an “official” political matter. The high proportion of legislation and political positions conveys the image that refugee affairs are a state or intergovernmental matter, an “official”, legal, political issue rather than for example a humanitarian question. Most of the articles published in both papers write about problems and conflicts in connection with refugee affairs. The negative media image has different significance for different topics. We argue that the question of refugee affairs is a topic where the image shown by the media is of great relevance: the media can be a more important source of information on this subject than personal contacts.
Quantum Particle Motion in Absorbing Harmonic Trap
B. G. Márkus,F. Márkus
Physics , 2015, DOI: 10.1007/s12648-015-0774-9
Abstract: The motivation of this work is to get an additional insight into the irreversible energy dissipation on the quantum level. The presented examination procedure is based on the Feynman path integral method that is applied and widened towards the calculation of the kernel of a quantum mechanical damped oscillator. Here, it is shown that the energy loss of the oscillator can be generated by the introduced harmonic complex potential. The related damped wave function, however, does not pertain to the probability meaning as it is usual in the case of complex absorbing potentials. This decrease of the wave function is evaluated, moreover, the energy dissipation and the measure the irreversibility are expressed.
A long range dependent model with nonlinear innovations for simulating daily river flows
P. Elek,L. Márkus
Natural Hazards and Earth System Sciences (NHESS) & Discussions (NHESSD) , 2004,
Abstract: We present the analysis aimed at the estimation of flood risks of Tisza River in Hungary on the basis of daily river discharge data registered in the last 100 years. The deseasonalised series has skewed and leptokurtic distribution and various methods suggest that it possesses substantial long memory. This motivates the attempt to fit a fractional ARIMA model with non-Gaussian innovations as a first step. Synthetic streamflow series can then be generated from the bootstrapped innovations. However, there remains a significant difference between the empirical and the synthetic density functions as well as the quantiles. This brings attention to the fact that the innovations are not independent, both their squares and absolute values are autocorrelated. Furthermore, the innovations display non-seasonal periods of high and low variances. This behaviour is characteristic to generalised autoregressive conditional heteroscedastic (GARCH) models. However, when innovations are simulated as GARCH processes, the quantiles and extremes of the discharge series are heavily overestimated. Therefore we suggest to fit a smooth transition GARCH-process to the innovations. In a standard GARCH model the dependence of the variance on the lagged innovation is quadratic whereas in our proposed model it is a bounded function. While preserving long memory and eliminating the correlation from both the generating noise and from its square, the new model is superior to the previously mentioned ones in approximating the probability density, the high quantiles and the extremal behaviour of the empirical river flows.
The Third Condition: the meaning of walls and gates in China Третье состояние: значение стен и ворот в Китае
Маrkus Appenzeller
Project Baikal , 2013,
Abstract: Walls in different cultural environments have different meaning. While this differs only gradually in western culture, in Chinese culture, they often have a very different meaning. Walls and the gates as the crossing points have a long tradition that dates back to the ancient empire. This cultural heritage has been used and adapted over the course of time, adding layer over layer and become integral part of both Chinese tradition and the contemporary Chinese city. Стены в разных культурных контекстах имеют разное значение. В Китае они несут значительную смысловую нагрузку. Стены и ворота как точка перехода имеют давнюю традицию, сложившуюся еще во времена древней империи. Это культурное наследие не переставало использоваться и совершенствоваться с течением времени, становясь неотъемлемой частью как традиций Китая, так и современного китайского города.
Visual Pathways Serving Motion Detection in the Mammalian Brain
Alice Rokszin,Zita Márkus,Gábor Braunitzer,Antal Berényi,Gy?rgy Benedek,Attila Nagy
Sensors , 2010, DOI: 10.3390/s100403218
Abstract: Motion perception is the process through which one gathers information on the dynamic visual world, in terms of the speed and movement direction of its elements. Motion sensation takes place from the retinal light sensitive elements, through the visual thalamus, the primary and higher visual cortices. In the present review we aim to focus on the extrageniculo-extrastriate cortical and subcortical visual structures of the feline and macaque brain and discuss their functional role in visual motion perception. Special attention is paid to the ascending tectofugal system that may serve for detection of the visual environment during self-motion.
A time domain based method for the accurate measurement of Q-factor and resonance frequency of microwave resonators
B. Gyüre,B. G. Márkus,B. Bernáth,F. Murányi,F. Simon
Physics , 2015, DOI: 10.1063/1.4929865
Abstract: We present a novel method to determine the resonant frequency and quality factor of microwave resonators which is faster, more stable, and conceptually simpler than the yet existing techniques. The microwave resonator is irradiated at a frequency away from its resonance. It then emits an exponentially decaying radiation at its eigen-frequency when the excitation is rapidly switched off. The emission is down-converted with a microwave mixer, digitized and its Fourier transformation (FT) directly yields the resonance curve in a single shot. Being an FT based method, this technique possesses the Fellgett (multiplex) and Connes (accuracy) advantages and it conceptually mimics that of pulsed nuclear magnetic resonance. We also establish a novel benchmark to compare accuracy of the different approaches of microwave resonator measurements. This shows that the present method have similar accuracy to the existing ones.

Abstract: alzheimer?s disease is a neurodegenerative disorder that provokes a progressive loss of memory and of other cognitive functions, with additional symptoms in the behavioural and psychological sphere, loss of autonomy and an important overburdening for the family and the social milieu. dealing with this disorder and other related dementias requires a multidimensional strategy that is able to face the different needs raised by the patient and his family. given the lack of a curative pharmacological treatment, psychosocial interventions have emerged over the years that are directed at optimising the function of the patient and supporting the family in caring for him, with very different techniques in each of the spheres of intervention (cognitive, behavioural, environmental, family). in this review, we make a description of the interventions that have been most studied in the field of cognitive stimulation, from the most global approaches (reality orientation therapy, reminiscence therapy, psychostimulation programs) to the most specific ones in the field of memory rehabilitation (training of the explicit memory, technique of delayed remembrance, vagueness, error-free learning, procedure training of the memory and the use of external help), and the results are shown of some studies carried out using these techniques of intervention.
Estimulación psicocognoscitiva en las demencias Psychocognitive stimulation in dementias

Anales del Sistema Sanitario de Navarra , 2003,
Abstract: La enfermedad de Alzheimer es un trastorno neurodegenerativo que provoca una progresiva pérdida de memoria y de otras funciones cognitivas, con síntomas también en la esfera conductual y psicológica, pérdida de autonomía y todo ello con una importante sobrecarga para la familia y el entorno social. El abordaje de este trastorno y de otras demencias afines requiere una estrategia multidimensional que pueda afrontar las diversas necesidades que plantea el enfermo y su familia. En ausencia de un tratamiento farmacológico curativo, a lo largo de los a os, han ido surgiendo intervenciones psicososiales dirigidas a optimizar la función del enfermo y apoyar a la familia en su cuidado, técnicas muy diversas en cada uno de los ámbitos de intervención (cognitivo, conductual, ambiente, familiar). En esta revisión, hacemos una descripción de las intervenciones más estudiadas en el campo de la estimulación cognitiva, desde las aproximaciones más globales (terapia de orientación a la realidad, terapia de reminiscencia, programas de psicoestimulación) a las más específicas en el campo de la rehabilitación de la memoria (entrenamiento de memoria explícita, técnica de recuerdo demorado, difuminación, aprendizaje sin error, entrenamiento de memoria procedimental y empleo de ayudas externas), y se muestran los resultados de algunos estudios realizados siguiendo estas técnicas de intervención. Alzheimer’s disease is a neurodegenerative disorder that provokes a progressive loss of memory and of other cognitive functions, with additional symptoms in the behavioural and psychological sphere, loss of autonomy and an important overburdening for the family and the social milieu.

Sobolev orthogonal polynomials on product domains
L. Fernández,F. Marcellán,T. E. Pérez,M. A. Pi?ar,Y. Xu
Mathematics , 2014,
Abstract: Orthogonal polynomials on the product domain $[a_1,b_1] \times [a_2,b_2]$ with respect to the inner product $$ \langle f,g \rangle_S = \int_{a_1}^{b_1} \int_{a_2}^{b_2} \nabla f(x,y)\cdot \nabla g(x,y)\, w_1(x)w_2(y) \,dx\, dy + \lambda f(c_1,c_2)g(c_1,c_2) $$ are constructed, where $w_i$ is a weight function on $[a_i,b_i]$ for $i = 1, 2$, $\lambda > 0$, and $(c_1, c_2)$ is a fixed point. The main result shows how an orthogonal basis for such an inner product can be constructed for certain weight functions, in particular, for product Laguerre and product Gegenbauer weight functions, which serve as primary examples.
