The perception of visual motion is critical for animal navigation, and flies are a prominent model system for exploring this neural computation. In Drosophila, the T4 cells of the medulla are directionally selective and necessary for ON motion behavioral responses. To examine the emergence of directional selectivity, we developed genetic driver lines for the neuron types with the most synapses ...

Current research in perception, cognition, and human-computer interaction is explored as a source of theories explaining the process by which threedimensional forms are visualized. A number of theoretical models are summarized and compared in an attempt to uncover variables important to future research conducted by the EDG profession. The appropriateness of dynamic versus static imaging techniq...

Annitto (1981) has criticized my work on the nature of hallucinations (March 1979). One of his points--the need to take the patient's affective state into account--is valid. His other criticisms--that I propose to use my outline of hallucination types for diagnostic purposes and that I have blamed the patient--are serious misconstructions of my work. A number of psychological techniques used fo...

This text is a revision of the most important theoretical approaches that fundament the studies about Mental Health and Work, pointing to the basic concepts, categories of analyses and respective limits. The objective is to underline some conceptions about the theme, in the attempt to contribute with a way to face the problems, questions and difficulties imposed by the construction of this obje...

Elucidating how enzymes enhance the rates of the reactions that they catalyze is a major goal of contemporary biochemistry, and it is an area in which computational and theoretical techniques can make a major contribution. This article outlines some of the processes that need to be investigated if enzyme catalysis is to be understood, reviews the current state-of-the-art in enzyme simulation wo...

Vital detection on the basis of Doppler radars has drawn a great deal of attention from researchers because of its high potential for applications in biomedicine, surveillance, and finding people alive under debris during natural hazards. In this research, the signal-to-noise ratio (SNR) of the remote vital-sign detection system is investigated. On the basis of different types of noise, such as...

Three-Phase Fluidized Beds have found an important place in processing technology as Reactors. Gas-Liquid-Solid fluidization is considered in the present paper as operating bed of fluidized solid particles simultaneously with co-current upward flow of a continuous liquid phase and a gaseous phase dispersed in the form of bubbles. In the present study, the experimental work of the author on heat...

Colour filters based on nano-apertures in thin metallic films have been widely studied due to their extraordinary optical transmission and small size. These properties make them prime candidates for use in high-resolution colour displays and high accuracy bio-sensors. The inclusion of polarization sensitive plasmonic features in such devices allow additional control over the electromagnetic fie...
