Facets of vision by D. G Stavenga( Book )

14 editions published between 1989 and 2012 in English and held by 174 WorldCat member libraries worldwide

This book is a comprehensive review providing an overview of modern compound eye research. The historical development of the field is also sketched, referring in particular to the pioneering study of Sigmund Exner - whose 1891 monograph is at last available in English (please see below). Facets of Vision is also intended as a tribute to Professor H. Autrum, one of this century's major pioneers of the field. The present state of compound eye research is reviewed by acknowledged international experts, starting with optics and proceeding, through neural processing, to visually guided behaviour. Topics covered include: fundamental optical principles and diversity of optical design, photochemistry, phototransduction, eye pigments, neuroanatomy, circadian rhythms, early visual processing, neuropharmacology, colour vision, polarization vision, depth vision and motion detection. Comprising a coherent compilation of authoritative reviews, Facets of Vision will stand as a milestone in compound eye research
Molecular mechanisms in visual transduction by D. G Stavenga( Book )

12 editions published in 2000 in English and held by 129 WorldCat member libraries worldwide

Molecular mechanisms in visual transduction is presently one of the most intensely studied areas in the field of signal transduction research in biological cells. Because the sense of vision plays a primary role in animal biology, and thus has been subject to long evolutionary development, the molecular and cellular mechanisms underlying vision have a high degree of sensitivity and versatility. The aims of visual transduction research are first to determine which molecules participate, and then to understand how they act in concert to produce the exquisite electrical responses of the photoreceptor cells. Since the 1940s, we have known that rod vision begins with the capture of a quantum of energy, a photon, by a visual pigment molecule, rhodopsin. As the function of photon absorption is to convert the visual pigment molecule into a G-protein activating state, the structural details of the visual pigments must be explained from the perspective of their role in activating their specific G-proteins. Thus, chapters 1-3 of this handbook extensively cover the physico-chemical molecular characteristics of the vertebrate rhodopsins.; Following photoconversion and G-protein activation, the phototransduction cascade leads to modifications of the population of closed and open ion channels in the photoreceptor plasma membrane, and thereby to the electrical response. The nature of the channels of vertebrate photoreceptors is examined in chapter 4, and chapter 5 integrates the present body of knowledge of the activation steps in the cascade into a quantitative framework. Once the phototransduction cascade is activated, it must be subsequently silenced. The various molecular mechanisms participating in inactivation are treated in chapters 1-4 and especially, chapter 5. Molecular biology is now an indispensable tool in signal transduction studies. Numerous vertebrate (chapter 6) and invertebrate (chapter 7) visual pigments have been characterized and cloned. The genetics and evolutionary aspects of this great subfamily of G-protein activating receptors are intriguing as they present a natural probe for the intimate relationship between structure and function of the visual pigments

3D Printing of NiZn ferrite/ABS Magnetic Composites for Electromagnetic Devices( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

ABSTRACT: 3D printing is a versatile fabrication method that offers the potential to realize complex 3D devices with metamaterial characteristics in a single process directly from a computer aided design. However, the range of functional devices that might be realized by 3D printing is limited by the current range of materials that are compatible with a given 3D printing process: fused deposition modelling (FDM), which is a widely used 3D printing method, typically employs only common thermoplastics. Here we describe the development of a magnetic feedstock based on polymer-ferrite composite that is compatible with FDM. The feasibility of the technique is demonstrated by the permittivity and permeability measurement of direct printed blocks and the fabrication of a complex 3D diamond-like lattice structure. The development of printable magnetic composites provides increased design freedom for direct realization of devices with graded electromagnetic properties operating at microwave frequencies
Functional interplay of visual, sensitizing and screening pigments in the eyes of Drosophila and other red‐eyed dipteran flies( )

1 edition published in 2017 in English and held by 1 WorldCat member library worldwide

Abstract :  Functional interplay of visual and screening pigments in the eyes of long‐horned flies (left; Diptera: Nematocera) and short‐horned flies (right; Diptera: Brachycera). The seven circles in the central enlarged facet indicate the rhabdomeres, where the six peripheral rhabdomeres contain green‐sensitive rhodopsin (Nematocera) with a blue‐shifted metarhodopsin isoform (blue circle around the green dot), or blue‐sensitive rhodopsin (Brachycera) with a red‐shifted metarhodopsin isoform (red circle around the blue dot). The seventh, central rhabdomere (violet, green and blue spot) contains UV‐, blue‐ and green‐sensitive rhodopsins with the corresponding blue‐ or green‐sensitive metarhodopsins. The photoreceptor somas contain yellow screening pigment. The dark brown screening pigment (Nematocera) or red screening pigment (Brachycera) in the pigment cells optically isolate the ommatidia and produce the eye colour. The nematoceran dark brown pigment absorbs all UV and visible wavelengths, while the brachyceran red pigment allows red stray light (red arrow) to reisomerize the metarhodopsin into rhodopsin, thus restoring the peripheral photoreceptors' sensitivity. The red stray light may cause reduction of the angular and contrast sensitivity of the green‐sensitive central photoreceptor. Abstract: Several fly species have distinctly red‐coloured eyes, meaning that the screening pigments that provide a restricted angular sensitivity of the photoreceptors may perform poorly in the longer wavelength range. The functional reasons for the red transparency and possible negative visual effects of the spectral properties of the eye‐colouring screening pigments are discussed within the context of the photochemistry, arrestin binding and turnover of the visual pigments located in the various photoreceptor types. A phylogenetic survey of the spectral properties of the main photoreceptors of the Diptera indicates that the transition of the brown eye colour of the Nematocera and lower Brachycera to a much redder eye colour of the higher Brachycera occurred around the emergence of the Tabanidae family

Plasmon optics and thermal dissipation in nanocomposite thin films( )

in English and held by 1 WorldCat member library worldwide

ABSTRACT: Optical properties and thermal relaxation dynamics of resonantly excited plasmons are important in applications for optoelectronics, biomedicine, energy, and catalysis. Geometric optics of polydimethylsiloxane (PDMS) thin films containing uniformly or asymmetrically distributed polydisperse reduced AuNPs or uniformly distributed monodisperse solution-synthesized AuNPs were recently evaluated using a compact linear algebraic sum. Algebraic calculation of geometric transmission, reflection, and attenuation for AuNP-PDMS films provides a simple, workable alternative to effective medium approximations, computationally expensive methods, and fitting of experimental data. This approach allows for the summative optical responses of a sequence of 2D elements comprising a 3D assembly to be analyzed. Thin PDMS films containing 3-7 micron layers of reduced AuNPs were fabricated with a novel diffusive-reduction synthesis technique. Rapid diffusive reduction of AuNPs into asymmetric PDMS thin films provided superior photothermal response relative to thicker films with AuNPs reduced throughout, with a photon-to-heat conversion of up to 3000°C/watt which represents 3-230-fold increase over previous AuNP-functionalized systems. Later work showed that introduction of AuNPs into PDMS enhanced thermoplasmonic dissipation coincident with internal reflection of incident resonant irradiation. Measured thermal emission and dynamics of AuNP-PDMS thin films exceeded emission and dynamics attributable by finite element analysis to Mie absorption, Fourier heat conduction, Rayleigh convection, and Stefan-Boltzmann radiation. Refractive-index matching experiments and measured temperature profiles indicated AuNP-containing thin films internally reflected light and dissipated power transverse to the film surface. Enhanced thermoplasmonic dissipation from metal-polymer nanocomposite thin films could affect opto- and bio-electronic implementation of these systems
Towards Alpha Radiation Detection in Aqueous Solution: VLSI Technology Development for Diamond-Silicon Hybrid Sensors( )

1 edition published in 2015 in English and held by 1 WorldCat member library worldwide

ABSTRACT: In the presented work, we have developed VLSI technology processes for new prototype sensors based on the synthesis of boron doped nanocrystalline diamond (B-NCD) and silicon based commercial detectors. The process is based on commercial passivated implanted planar silicon (PIPS) devices of PD450 and CAM450 types (CANBERRA). A layer of B-NCD of several hundred nanometers thickness and boron concentration up to 10 21 atoms/cm 3 is grown on the SiOx passivation layer in an ellipsoidal plasma enhanced chemical vapor deposition (PECVD) reactor at temperatures from 520-750°C, in hydrogen atmosphere. . The diamond electrode is dry chemically structured and aluminum electrodes are realized before mounting in a three-fold housing for measurements in aqueous solution. The prototype sensors show an alpha spectroscopy resolution of 100 keV for 241 Am electroprecipitated from liquid solution

Inkjet-printed quantum dot-based sensor for structural health monitoring( )

in English and held by 1 WorldCat member library worldwide

ABSTRACT: A sensor which detects mechanical stresses and stores the position and the strength of these loads by color change of embedded quantum dots (QDs) is presented. The top and bottom electrodes of the sensor are inkjet-printed which leads to a fast and accurate deposition of thin (approx. 50 - 300 nm) and conductive layers. The used silver and poly(3, 4-ethylenedioxythio-phene) polystyrene sulfonate (PEDOT:PSS) inks are optimized in terms of printability and opportunities of functionality forming without influencing the active layer of the sensor. The active layer of the sensor is spin-coated and consists of the QDs embedded in semi-conducting poly(9-vinylcarba-zole) (PVK). The hole transport characteristic of PVK and the band level alignment of the used materials ensures the preferred injection of only one type of charge carrier into the QDs. As a result the mechanical stress is visualized by a decreasing in photoluminescence (PL) of the QDs
Comparative physiology and evolution of vision in invertebrates by Hansjochem Autrum( )

1 edition published in 1979 in English and held by 0 WorldCat member libraries worldwide

In the comparative physiology of photoreception by the Protista and the invertebrates two aspects are emphasized: (1) the diversity of visual processes in these groups and (2) their bearing upon general mechanisms of photoreception. Invertebrates have evolved a far greater variety of adaptations than vertebrates modifications aiding survival in the remarkably different biotopes they occupy. The number of species in itself suggests this multiformity; each of them has peculiarities of its own, in morphology as well as in physiology and behavior. But these special adaptations are variations on a few great themes. Although the catalogue of invertebrate species is immense, the literature concerning them nearly rivals it in extent-even if one considers only that fraction dealing with visual physiology. Taxonomy proceeds by grouping the species, categorizing them in genera, families, orders, and progressively larger units. Similarly, comparative physiology aims at an analogous, more or less compre hensive, classification. This Part A of Volume VII/6, like Part B that follows it, emphasizes the broad questions that concern groups larger than the individual species; in some cases these questions have general applicability. The middle course between approaches that are too specialized and those that are too general is often elusive, but here we attempt to follow it. The vast number of special adaptations-probably, as we have said, as large as the number of species-is beyond the range even of a handbook
