[A report of 412 consecutive posterior chamber intraocular lens implantations]. (1994)

The series of 412 consecutive PC IOL implantations comprised 337 eyes of senile cataract, 16 eyes of membranous cataract, 25 eyes of traumatic cataract, 13 eyes of congenital cataract, 10 eyes of complicated cataract and 11 eyes of aphakia. 362 eyes were postoperatively followed up from 4 weeks to 1 1/2 years with the results that 251 (69.3%) eyes obtained visual acuities of 0.8 or over, and 328 (90.6%) eyes 0.5 or over. The authors discussed the technical improvement in anterior capsulotomy and the implantation procedures in cases of posterior capsule rupture. The importance of postoperative control and management of astigmatism, in the recovery of visual acuity was pointed out.
BIST using genetic algorithm for error detection and correction (2012)

This paper presents a low peak power consumption BIST based on genetic algorithm (GA) is applied for viterbi decoder error detection and correction, denoted by GAITPGEDC. This method aims at reducing the changes between successive test pattern. Here m-1 test vectors are inserted between two successive n-bit generated by linear feedback shift registers (LFSR), where m and elements of group were optimized by GA. Thus the switching activities of test vectors are greatly reduced in test mode without compromising fault coverage. The proposed structure has the advantages of low test. Experiments conducted on ISCAS'89 benchmark circuits demonstrate that proposed scheme gives better fault coverage and with viterbi decoder error detection and correction was performed with a large reduction in power dissipation during testing.
Search Performance of Healthy Adults on Cancellation Tests (2008)

Cancellation tests are used extensively to identify visual search deficiencies in people with neurologic conditions, but little is known about how healthy adults perform on these tests. This study described the performance and types of search strategies used by healthy adults to complete cancellation tests from the Brain Injury Visual Assessment Battery for Adults. Study participants predominantly used structured left-to-right and top-to-bottom linear search patterns regardless of the configuration of the visual array. Other search qualities included (1) use of the same pattern throughout the search of an array, (2) symmetrical search of the array, and (3) rechecking performance on complex arrays. Older adult participants took more time to complete the tests than younger adults did. Knowing the strategies healthy adults use on cancellation tests enables therapists to identify visual search deficiencies in clients and design interventions to reestablish normal search strategies in daily occupations.
LEARNING ROBOT BEHAVIORS USING GENETIC ALGORITHMS (1994)

Genetic Algorithms are used to learn navigation and collision avoidance behaviors for robots. The learning is performed under simulation, and the resulting behaviors are then used to control the actual robot. THE LEARNING PARADIGM The approach to learning behaviors for robots described here reflects a particular methodology for learning via a simulation model. The motivation is that making mistakes on real systems may be costly or dangerous. In addition, time constraints might limit the number of experiences during learning in the real world, while in many cases, the simulation model can be made to run faster than real time. Since learning may require experimenting with behaviors that might occasionally produce unacceptable results if applied to the real world, or might require too much time in the real environment, we assume that hypothetical behaviors will be evaluated in a simulation model (the off-line system). As illustrated in Figure 1, the current best behavior can be placed in...

Political economies and environmental futures for the sharing economy (2017)

The sudden rise of the sharing economy has sparked an intense public debate about its definition, its effects and its future regulation. Here, I attempt to provide analytical guidance by defining the sharing economy as the practice that consumers grant each other temporary access to their under-utilized physical assets. Using this definition, the rise of the sharing economy can be understood as occurring at the intersection of three salient economic trends: peer-to-peer exchange, access over ownership and circular business models. I shortly discuss some of the environmental impacts of online sharing platforms and then articulate three possible futures of the sharing economy: a capitalist future cumulating in monopolistic super-platforms allowing for seamless services, a state-led future that shifts taxation from labour to capital and redistributes the gains of sharing from winners to losers, and a citizen-led future based on cooperatively owned platforms under democratic control. The nature and size of the social and environmental impacts are expected to differ greatly in each of the three scenarios.This article is part of the themed issue 'Material demand reduction'.
SEROLOGICALLY DEFINED AND LYMPHOCYTE-DEFINED COMPONENTS OF THE MAJOR HISTOCOMPATIBILITY COMPLEX IN THE MOUSE (1972)

The mixed leukocyte culture (MLC) test is an in vitro model of the recognition phase of the homograft response. For the most part, activation in MLC is dependent on differences of the major histocompatibility complex (MHC). Our present studies in the mouse suggest that activation is primarily associated with differences of genetic regions of the MHC other than those which control the serologically defined (H-2) antigens. These differences do not lead to cytotoxic or agglutinating antibody formation despite extensive immunization; we have called these differences lymphocyte-defined (LD) differences. The strongest stimulation in MLC is associated with differences of the Ir region. It is possible that the Ir product is the T cell receptor and that it is this same molecule which can act as the stimulatory agent in MLC. Other possibilities are discussed.
Identification of microRNA-mRNA functional interactions in UVB-induced senescence of human diploid fibroblasts (2013)

We performed a comprehensive screen for UVB-regulated microRNAs in human diploid fibroblasts, and identified a network of miRNA-mRNA interactions mediating UVB-induced senescence. In addition, miR-101 and Ezh2 were identified as key players in UVB-induced senescence of HDF.

Commentary Paper 2 on "On Stable Dynamic Background Generation Technique Using Gaussian Mixture Models for Robust Object Detection'" (2008)

In previous surveillance applications, algorithms for background modeling based on Gaussian mixture models (GMM) needed to specify two parameters: threshold T, which determines a proportion of the data that should be accounted for by the background, and a learning rate alpha specifying speed at which the distribution parameters change [Stauffer, CVPR 1999}. In the Basic Background Subtraction (BBS), foreground objects are found by subtracting a static foreground image. In the proposed algorithm, BBS is applied using background obtained from GMM. This way, threshold T is replaced by a foreground-background separation threshold S. The advantage is that S is less sensitive than T. To make the model respond faster to changes, recent observed value of the most dominant background component is used as a current value for a particular pixel, rather than the component mean value. Quantitative and qualitative results show the advantages of the proposed technique compared to GMM models.
Knowledge based control in micro-architecture design (1987)

This paper describes the principles and implementation of design-process control in a micro-architecture compiler. The knowledge-base relies on both local and global evaluations to determine strategies to achieve global goals and then implements those strategies by manipulating hardware allocations and search heuristics. A system overview and annotated sample run are presented.
Automatic assessment of contextual web accessibility from an evaluation, measurement and adaptation perspective (2009)

La accesibilidad a la Web permite que las personas con discapacidad puedan disfrutar de una experiencia de usuario libre de barreras, Esta tesis doctoral explora como los expertos en accesibilidad y los usuarios finales se pueden beneficiar de la valoracion automatica de la accesibilidad. En este documento se entiende por valoracion de la accesibilidad al proceso de evaluacion y medicion.

Los expertos en accesibilidad pueden hacer uso de un conjunto de herramientas suficientemente flexible como para crear y mantener contenido web accesible teniendo en cuenta multitud de usuarios y escenarios de interaccion. Asimismo, las tecnicas y metodos utilizados para el desarrollo de herramientas y expuestos en esta tesis pueden ser replicados y reutilizados por terceros. La valoracion de catorce sitios web hecha por un panel de expertos y la valoracion automatica a larga escala de casi 1.500 paginas web concluyen que la metrica Web Accessibility Quantitative Metric (WAQM) es fiable y valida cuando se pretende medir la accesibilidad web automaticamente. Ademas, al desplegar la metrica WAQM en los resultados de buscadores web comerciales (Google y Yahoo!) se corrobora la teoria de que los crawlers que rastrean la Web se comportan como usuarios ciegos y por ello consideran la accesibilidad en el proceso de recuperacion de informacion aunque la lista de resultados no este ordenada de acuerdo al nivel de accesibilidad de cada pagina.

Los usuarios finales pueden sacar provecho de las valoraciones de la accesibilidad contextual cuando estas se despliegan en paginas web con el objetivo de incrementar la orientacion del usuario. Para llevar al cabo dichas valoraciones no solo se tienen que tener en cuenta las pautas para contenido accesible sino tambien las dependencias que pueda haber entre estas y grupo de usuario, tecnologia asistencial y dispositivo de acceso. Un test con veinte usuarios concluye que esta propuesta es valida dado que la valoracion de la accesibilidad adaptada al dispositivo de acceso es mucho mas fiel a la evaluacion de la usabilidad en terminos de satisfaccion y en el tiempo para completar la tarea. Otro test con dieciseis usuarios ciegos demuestra que al desplegar la valoracion de la accesibilidad en paginas web aumenta la orientacion y la confianza del usuario. Tambien se observa que cuando los enlaces estan anotados con la puntuacion de la accesibilidad de la pagina web a la que apuntan el paradigma de navegacion cambia de una navegacion secuencial a una donde los usuarios solo navegan de una manera aleatorio en aquellos enlaces que son mas accesibles.

Es significativo que las lecciones aprendidas en esta tesis no solo se pueden aplicar en la valoracion automatica de la accesibilidad sino que se pueden extrapolar a las valoraciones hechas por expertos y aquellas llevadas a cabo con usuarios finales.
Electrochemistry of polyacetylene, (CH)x. Characteristics of polyacetylene cathodes (1982)

The relationship of cell potential to degree of oxidation, coulombic and energy efficiencies, constant-current discharge characteristics, energy density and maximum power density of a partly oxidized polyacetylene, [CH(ClO4)y](y [graphic omitted] 0.07), cathode in a cell of the type [CH(ClO4)y]x|LiClO4|Li are discussed. Coulombic efficiencies ranging from 100 to 86% and energy efficiencies ranging from 81 to 68% during a charge–discharge cycle are found at oxidation levels ranging from 1.54 to 6.0%. Energy densities of ca. 255 W h kg–1(based on the weights of the electroactive materials involved in the discharge process) are obtained for 7.0% oxidized polyacetylene cathodes under constant-current discharge conditions. Maximum power densities of ca. 30 kW kg–1 are observed.
A new technique for explantation and in vitro cultivation of chicken embryos (1991)

A technique is described for explanting and cultivating chicken embryos in plastic drinking cups which have been modified with plastic wrap to reproduce the geometry and dimensions of the egg shell. Successful explantation rates of 97% are possible with a double-window technique, and survivability in cups exceeds that achievable in other in vitro systems (i.e., petri dishes). Long-term survival to the 21st day of incubation is seen routinely. This system with cups is less expensive than that with petri dishes, and simpler than that with plastic wrap/tripods. Thus, this new method of in vitro cultivation of chicken embryos improves upon explantation rate, survivability and system design, and has a wide range of applications in developmental biology, angiogenesis, cancer, and pharmacology research.
Determining states of inevitable collision using reachability analysis (2014)

In this paper the states of inevitable collision for mobile robots are determined using reachable set theory. With this theory the safety for robotic platforms can be guaranteed, still allowing maximum flexibility for navigation. Making use of reachability analysis, limitations due to input sampling as in previous approaches are avoided. Using reachability analysis the obstacles are grown in the state space. The mathematical background is shown in this paper and an exemplary algorithm is given for static environments. This implementation can handle arbitrary environments with multiple obstacles and different high-dimensional linear and non-linear system dynamics including the car-like kinematic model. By means of experimental results in simulated environments, the validity of the proposed concept is shown.
A Soluble Form of the MHC Class I-Specific CD160 Receptor Is Released from Human Activated NK Lymphocytes and Inhibits Cell-Mediated Cytotoxicity (2007)

CD160 is a GPI-anchored lymphocyte surface receptor in which expression is mostly restricted to the highly cytotoxic CD56(dim)CD16(+) peripheral blood NK subset. We previously reported that MHC class I (MHC-I) molecules bind to CD160 receptors on circulating NK lymphocytes and that this interaction triggers their cytotoxic activity and cytokine production. We also observed that CD160 surface expression on NK cells is down-modulated upon activation with PMA or IL-2. In this study, we further report that short-time incubation of NK lymphocytes with IL-15 converts the membrane-bound CD160 to a soluble form through a proteolytic cleavage involving a metalloprotease. Thus, CD160 is no longer detected at the cell surface, but can be immunoprecipitated from the NK cell culture medium. Interestingly, CD160 transcript remains highly expressed during the process of protein shedding. In addition, we demonstrate that CD160 mRNA synthesis can be induced in CD56(bright) separated lymphocytes following exposure to IL-15. By producing a Flag-tagged soluble CD160 protein, we establish that its binding to MHC-I molecules results in the inhibition of the cytotoxic CD8(+) T lymphocyte activity and of the CD160-mediated NK cell cytotoxicity. Thus, we show that activated NK lymphocytes release a soluble form of CD160 that functionally impairs the MHC-I-specific cytotoxic CD8(+) T lymphocyte responsiveness.
Performance of a multiplexed chemical ionization miniature cylindrical ion trap array mass spectrometer (2004)

The performance of a multiplexed array of miniature cylindrical ion trap (CIT) mass spectrometers composed of four identical sets of ion source/mass analyzer/detector channels is evaluated. Each miniature cylindrical ion trap (inner radius 2.5 mm) was coupled to an external chemical ionization/electron ionization (CI/EI) source and a miniature (inner diameter 2 mm) electron multiplier. The sample introduction system permits delivery of samples and reagent gases directly into any one or more of the ionization volumes. Experimental conditions were optimized as required for CI to occur in one or more ion volumes. The ion source potential was observed to affect the energy of [M + H]+ ions generated by self-chemical ionization in the external ion sources and, thus, the degree of fragmentation observed in resulting mass spectra. The versatility of this novel instrumentation permits two types of multi-channel experiments. In the first, different samples are analyzed at the same time in identical, parallel channels for high-throughput mass analysis using CI. In the second, the instrument is used for improved specificity in the analysis of a single sample by simultaneous measurements made with multiple methods of ionization, including EI and methane CI in adjacent channels of the instrument.
Wireless flexible smart bandage for continuous monitoring of wound oxygenation (2014)

Current methods in treating chronic wounds have had limited success in large part due to the open loop nature of the treatment. In turn, we have created a localized smart wound dressing platform that will allow for real time data acquisition of oxygen concentration at the wound site. This will serve as the first leg of a feedback loop for a fully optimized treatment mechanism tailored to the individual patient. A flexible oxygen sensor was synthesized with high sensitivity and linear current output. With a series of off-the-shelf electronic components including an analog front end, a microcontroller, and wireless radios, an integrated electronic system with data read-out and wireless transmission capabilities was assembled in a compact package. The front-end amplifier is fully programable with numerous internal gains, enabling the read-out system to monitor a wide range of oxygen concentrations. Using an elastomeric material, a bandage with exceptional flexibility and tensile strength was 3D-printed without sacrificing a low overall modulus. Our integrated, flexible platform is the first step toward providing a self-operating, highly optimized remote therapy for chronic wounds.
High-precision MRI-compatible force sensor with parallel plate structure (2008)

This paper presents an MRI-compatible optical force sensor: its principle, structure and performance. Our force sensor employs an optical micrometry based on differential measure of light intensity. This technology enables highly accurate and sensitive two degrees-of-freedom displacement sensing by using a point source, a photo detector and an optical lens. The developed force sensor achieves MRI compatibility by placing all the electric and metallic components outside MRI, and connecting the light path between the optical components by using multi-core optical fibers. The sensor head component has parallel plate structure and is made of glass fiber reinforced poly-ether-ether-keton those help reducing axial interference and hysteresis characteristics of plastic resin. The accuracy of this force sensor is better than 1.6 %F.S. under the applied force ranging from 0 to 3 N.

Sooting Characteristics of Surrogates for Jet Fuels (2009)

New measurements of threshold soot index (TSI) and TSI data from the literature have been combined to develop a set of recommended TSI values for use in formulating surrogate fuel mixtures for JP-8. Several binary mixtures of candidate surrogate compounds were tested in order to verify the mixture rule for the TSI. The mixtures were also used to derive values of TSI for iso-cetane and to verify the value for 1-methylnaphthalene. Lastly, several surrogate mixtures of three or four components were tested to see how well their TSI's matched their predicted values, and to show that a target value of TSI can be maintained when components and composition change.
