Psychologische Befunde zu Licht und seiner Wirkung auf den Menschen – ein Überblick (2013)

Abstract Ziel des vorliegenden Beitrags ist es, die Wirkung von Licht auf den Menschen aus Sicht der Psychologie darzustellen und einen Überblick aktueller psychologischer Forschungsbefunde zum Einfluss von Licht und Beleuchtungssystemen darzubieten. Um Beleuchtung optimal einsetzen zu können, ist es erforderlich, sowohl die Wirkweisen von Licht als auch den Einfluss von Licht und Beleuchtung auf Leistung, Wohlbefinden und Verhalten von dessen Nutzern zu kennen. Dementsprechend wird zunächst die grundlegende Wirkung von Licht auf den Menschen dargestellt, gefolgt von einem umfassenden Überblick der wichtigsten psychologischen Forschungsbefunde zum Einfluss von Licht auf Arbeitsleistung, Gesundheit und Wohlbefinden, Interaktionen mit anderen Personen sowie dem Konsumbereich. Abschließend werden der aktuelle Stand des Wissens und der weitere Forschungsbedarf zusammengefasst. Psychological evidence on light and its impact on humans – an overview. The aim of the present article is to describe the light’s effects on humans from a psychological perspective and to give an overview of actual psychological research on the influence of light and illumination. In order to optimize lighting applications, it is necessary to know both the routes of influence via which light affects humans and the impact of light and illumination on user’s performance, wellbeing, and behavior. Consequently, we first outline the fundamental effect of light on humans and then summarize psychological evidence on the light’s influence on task performance, health and wellbeing, social interactions and consumer behavior. Building on this review, the current state of knowledge and need for further research are summarized.
Computational Indistinguishability Amplification: Tight Product Theorems for System Composition. (2009)

Computational indistinguishability amplification is the problem of strengthening cryptographic primitives whose security is defined by bounding the distinguishing advantage of an efficient distinguisher. Examples include pseudorandom generators (PRGs), pseudorandom functions (PRFs), and pseudorandom permutations (PRPs). The literature on computational indistinguishability amplification consists only of few isolated results. Yao’s XOR-lemma implies, by a hybrid argument, that no efficient distinguisher has advantage better than (roughly) n2m−1δm in distinguishing the XOR of m independent n-bit PRG outputs S1, . . . , Sm from uniform randomness if no efficient distinguisher has advantage more than δ in distinguishing Si from a uniform n-bit string. The factor 2m−1 allows for security amplification only if δ < 12 : For the case of PRFs, a random-offset XOR-construction of Myers was the first result to achieve strong security amplification, i.e., also for 12 ≤ δ < 1. This paper proposes a systematic treatment of computational indistinguishability amplification. We generalize and improve the above product theorem for the XOR of PRGs along five axes. First, we prove the tight information-theoretic bound 2m−1δm (without factor n) also for the computational setting. Second, we prove results for interactive systems (e.g. PRFs or PRPs). Third, we consider the general class of neutralizing combination constructions, not just XOR. As an application, this yields the first indistinguishability amplification results for the cascade of PRPs (i.e., block ciphers) converting a weak PRP into an arbitrarily strong PRP, both for single-sided and two-sided queries. Fourth, strong security amplification is achieved for a subclass of neutralizing constructions which includes as a special case the construction of Myers. As an application we obtain highly practical optimal security amplification for block ciphers, simply by adding random offsets at the input and output of the cascade. Fifth, we show strong security amplification also for weakened assumptions like security against random-input (as opposed to chosen-input) attacks. A key technique is a generalization of Yao’s XOR-lemma to (interactive) systems, which is of independent interest. ∗An extended abstract of this paper appears in the proceedings of CRYPTO 2009. This is the full version.
Proceedings Foundations for Interface Technologies (2011)

FIT stands for Foundations of Interface Technologies. Component-based design is widely considered as a major approach to developing systems in a time and cost effective way. Central in this approach is the notion of an interface. Interfaces summarize the externally visible properties of a component and are seen as a key to achieving component interoperability and to predict global system behavior based on the component behavior. To capture the intricacy of complex software products, rich interfaces have been proposed. These interfaces do not only specify syntactic properties, such as the signatures of methods and operations, but also take into account behavioral and extra-functional properties, such as quality of service, security and dependability. Rich interfaces have been proposed for describing, e.g., the legal sequences of messages or method calls accepted by components, or the resource and timing constraints in embedded software. The development of a rigorous framework for the specification and analysis of rich interfaces is challenging. The aim of this workshop is to bring together researchers who are interested in the formal underpinnings of interface technologies
Functional connectivity in patients with idiopathic generalized epilepsy (2011)

The results underscore the paroxysmal nature of GSWDs: Although GSWDs are characterized by highly synchronized activity in the thalamocortical network, the functional connectivity in areas involved during GSWDs does not demonstrate abnormality in GSWD-free periods.

SEVIRI, the new imager for Meteosat second generation (2002)

The "Spinning Enhanced Visible and InfraRed Imager" will be flown on the Meteosat second generation satellites. The mission objectives and major performance requirements are presented. The features of the 12 channels covering a wide spectral range from 0.5 /spl mu/m in the visible region to 14 /spl mu/m in the infrared domain are described, as are their respective meteorological applications. The instrument design and operating principle are described. Telescope and scan assembly, focal plane and cooler assembly, and instrument control and data handling are the most challenging optical instrumentation technologies. Expected instrument radiometric performances are summarised; improved spatial, temporal, spectral and radiometric resolutions will allow the image data to be used in future numerical weather prediction processes. The overall programme development plan foresees the manufacturing and testing of 4 satellites, the first launch being planned for the end of the nineties. The baseline instrument design presented in the paper has been carried out during the phase A study under an ESA contract.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Stacked thin dice packaging (2002)

This paper reports on a developed stacking method to produce a small volume three-dimensional package. The first part of the 3/sup rd/ dimension is tackled by reducing package thickness and also the stand-off height. The steps came through thinning dice, using a thin interposer, and to stack the components. The thickness of the used ICs was 90 /spl mu/m, whereas typically thicknesses are around 250-300 /spl mu/m. Thin dice were connected through eutectic solder bumps on thin aramid epoxy substrates. The package was studied with the finite element method (FEM) using three-dimensional (3-D) models and the Ansys program. The average plastic work in the solder bump was used to define the reliability of the structure. Structures with one to four layers are compared. In current flip-chip assemblies, rigidity assists good electrical performance and reliability. Reducing the IC thickness below 100 /spl mu/m creates new challenges for handling, interconnecting, reliability and design. These tasks have been addressed in this study. The designed circuits for the above tests have been characterized and more details of the results are presented. Further progress in density increase has been achieved by stacking layers of flexible substrate and thin die on top of each other. For this work, the first level connection has been flip-chip bonding. The goal was to develop a method to produce modules on a small scale to verify the feasibility of various System-in-Package (SiP) solutions. The method has been tested using thin dice, mainly daisy chain. Devices are miniaturized to be more comfortable to carry; this size reduction desire, together with increased functionality, have become drivers, especially for wireless devices. Size reduction of electronics has set a challenge for packaging and provided the motivation to verify emerging technologies.
A priority action roadmap for women's economic empowerment (PARWEE) amid COVID-19: a co-creation approach (2021)

Purpose The study aims to co-create a “priority action roadmap for women's economic empowerment” based on women's top priorities to charting recovery directions. Doing so contributes to the growing body of knowledge on COVID-19 literature in at least four areas: assessing COVID-19 impacts on women entrepreneurs; mapping these impacts with four interdependent women's entrepreneurial ecosystem components; innovating a co-creation methodology based on remote participatory research; and providing a replicable model to perform action-oriented research in the context of COVID-19 impacts. Design/methodology/approach A co-creation methodology is proposed, combining systems-thinking and remote participatory research to engage women entrepreneurs and institutional stakeholders to prioritize impact, response actions and recovery needs in the wake of COVID-19. A ranking exercise using the analytic hierarchy process was used to derive ranking and assess user inputs' consistency. Findings The study exemplifies the integration of participatory methods and mathematical tool to engage stakeholders in prioritizing recovery work. PARWEE action items ranked by entrepreneurs and vetted by institutional stakeholders cover: access to finances, capacity building, health care, public and private partnership, marketing opportunities and formation of active advocacy groups to voice out women entrepreneurs' needs to institutional stakeholders. Results show a slight difference in the ranking of priority actions between experience owners and fresh starters. Originality/value This study innovated a new co-creation methodology for remotely engaging stakeholders of the women's entrepreneurial ecosystem, which is grounded in evidence and provides a replicable model for performing action-oriented research.
Electrochemical Measurement of Enzyme Reactions under Strong Magnetic Fields. (1996)

A biosensor (enzyme sensor) was used as a probe for monitoring an immobilized-enzyme reaction created in a static strong magnetic field by an electrochemical technique. We used a glucose sensor (biosensor), which was fabricated by immobilization of glucose oxidase (GOD) on an electrode, and detected the response current of the sensor in the bore of a superconducting magnet (with a magnetic field of 8 T at its center). The response current for a 1 mM glucose solution in a phosphate buffered solution (pH 6.5) decreased by 20% after magnetic field exposure for 100 minutes. The current recovered to 95% of its original strength when the sensor was removed from the bore. However, the response current for a 100 mM H2O2 solution decreased slightly for 90 minutes, but did not recover. From the results, we conclude that the enzyme-reaction process, in the reaction of glucose with GOD, was inhibited by an 8 T magnetic field.
Investigation of the environmental presence of Salmonella spp. in finishing pigs at commercial swine farms in Kansas (USA) (2023)

Salmonellosis remains a major foodborne disease threat to public health worldwide. Swine are considered a reservoir for many Salmonella serotypes affecting humans; however, not all serotypes of concern in food animal products cause clinical signs of infection in swine. The objective of this study was to evaluate the presence and distribution of Salmonella spp. in finishing pigs at commercial farms across Kansas (USA). Five farms were selected and sampled when pigs weighed between 125 and 136 kg. Samples were collected and transported to the laboratory for processing following USDA-FSIS guidelines. Susceptibility and resistance profiles were also studied. Fifty-three percent (100/186) of samples were culture positive for Enterobacteriaceae, and 14% (14/100) were confirmed Salmonella positive by PCR with three of five farms having no PCR-positive samples. Salmonella serotype Braenderup was the most common serovar identified in environmental samples, while Salm. Infantis, Agona, and Montevideo were identified in fecal samples. Multidrug resistance patterns were only found in Farm 3, in fecal samples and in one floor sample. The observations reported in this study highlight areas of concern, such as locations prone to fecal contamination, to be considered when cleaning and sanitizing between groups of pigs to decrease presence of Salmonella spp. in farm environments.
Modulation of Kit/stem cell factor receptor-induced signaling by protein kinase C. (1994)

The Kit/stem cell factor receptor (Kit/SCF-R) is a transmembrane tyrosine kinase receptor of importance for the normal development of hemopoietic cells, melanoblasts, and germ cells. We recently reported that protein kinase C (PKC) is involved in a negative feedback loop regulating the Kit/SCF-R by direct phosphorylation on serine residues in the receptor. Inhibition of PKC led to increased SCF-induced tyrosine kinase activity and mitogenicity, but PKC was necessary for SCF-induced motility. In this report we have further examined the modulatory role of PKC on SCF-induced signaling. The ligand-activated Kit/SCF-R associated weakly with GRB2 and induced only little tyrosine phosphorylation of phospholipase C-gamma in porcine aortic endothelial cells transfected with Kit/SCF-R. In contrast, the SCF-stimulated Kit/SCF-R associated efficiently with, and induced tyrosine phosphorylation of, the p85 alpha regulatory subunit of phosphatidyl inositide-3'-kinase (PI-3'-kinase). Both receptor association and tyrosine phosphorylation of p85 alpha were increased after inhibition of PKC, while its serine phosphorylation was decreased. Concomitantly, the specific activity of receptor-associated PI-3'-kinase activity was increased. Inhibition of PI-3'-kinase with wortmannin inhibited SCF-induced mitogenicity. SCF-induced phosphorylation of Raf-1 and activation of ERK2 still occurred after PKC inhibition but was not increased. In conclusion, SCF-induced PI-3'-kinase activation paralleled the increased SCF-induced mitogenicity after inhibition of PKC.
A Digitizing and Memory System for Wire Spark Chambers (1972)

A new digitizing and memory system for use with magnetostrictive wire spark chambers is described. Features include a 1000 spark per event 20 MHz shift register memory and a live CRT display of spark positions. Our design experience with state-of-the-art MOS shift registers and Schottky TTL circuits is presented, together with comments on our experience with the working system. This principle has applications in many other situations requiring the digitization and storage of the arrival times of a burst of pulses.
Poly2-methoxyethylacrylate (PMEA) Coated Oxygenator: An ex Vivo Study (2002)

When compared with uncoated oxygenator, PMEA coated oxygenator exhibited increased thrombus resistance with lower inlet pressure and lower thrombocyte consumption. In both groups, trauma to red cells was minimal, emphasizing the efficient design of this type of oxygenator.
Disruption Management of ASAE’s Inspection Routes (2022)

The Rapid development and the emergence of technologies capable of producing real-time data opened new horizons to both planning and optimization of vehicle routes [4]. In this dissertation, the Autoridade de Segurança Alimentar e Económica (ASAE) operation's scenario will be explored and analyzed as a case study to the problem. ASAE is a Portuguese administrative authority specialized in food security and economic auditing and is responsible to regulate thousands of economic entities in the Portuguese territory. ASAE inspections are usually done by brigades using vehicles to inspect economic operators, taking into account their timetables. Previous work on this topic led to the implementation of an inspection route optimization module capable of defining and assigning routes to inspect economic operators, seeking to maximize a utility function. Using optimization algorithms, inspection routes are calculated for each brigade, with information regarding specific map paths and inspection schedules. The approach used does not take into consideration the dynamic properties of real-life scenarios, as the precalculated operation plan is not reviewed in real-time. This work aims to study the dynamic properties of ASAE's operational environment and proposes a solution to efficiently review the precalculated inspection routes and apply the required changes in an appropriate time frame. Vehicle routing problems (VRP) are optimization problems where the aim is to calculate the set of optimized routes for a vehicle fleet, from a starting point to several interesting locations. Dynamic vehicle routing problem (DVRP) is a variant of VRP that makes use of real-time information to calculate the most optimized set of routes at a certain moment [39]. DVRP is a challenging problem because its scope is real-time, meaning that decisions sometimes must be made in short time windows, preventing the use of complex algorithms that require long computational times [10]. The typical approach to this problem is to initially calculate the routes for the whole fleet and dynamically revise the defined operations plan in real-time, once a disruption occurs. This work will model the problem as a DVRP and will compare the performance of heuristics and other modern optimization techniques, proposing a solution that will reduce the impact of disruptions on inspection routes. An optimized operations plan will reduce the time required for inspections, allowing massive economic savings, while reducing a company's ecological footstep. The work can eventually be scaled and used in other institutions, such as GNR or PSP in Portugal, that operate similarly.

Linear Viscoelastic Properties of Bituminous Materials Including New Products Made with Ultrafine Particles (2009)

ABSTRACT An experimental campaign has been performed at the ENTPE laboratory in order to measure the linear viscoelastic properties (shear complex modulus G*) of mastics with a specifically developed device (annular shear rheometer). Different fillers have been used to design mastics, among which a new type of filler only composed of ultrafine particles. The use of these ultrafine particles induces a significant increase in the complex modulus of mastics at high temperature in comparison to mastics with classical fillers. The potential for reinforcement of fillers is quantified by the complex reinforcement coefficient RM* introduced in this paper. The ultrafine particles have also been used in bituminous mixtures. As it is observed for mastics, an important increase of the modulus is observed at high temperature for the mixtures made with ultrafine filler. Finally, simulations of the linear viscoelastic behaviour of bituminous materials with 2S2P1D model developed at the ENTPE are proposed. Simulations fit quite well experimental results.
Indirect Excitation of micro-HRG Using Segmented Piezoelectric ALD PHT Actuator (2023)

This paper presents, for the first time, an indirect excitation method for three-dimensional fused quartz dual-shell micro-scale Hemispherical Resonator Gyroscope μHRG. The μHRG was fabricated using three wafer bonding and high-temperature micro-glassblowing processes, providing a sensing element (device shell), a self-aligned fixed-fixed anchor for increased immunity to mechanical shocks and vibrations, and a housing (cap shell) for vacuum encapsulation. The novel actuation technique uses piezoelectric actuation to transfer energy from the cap shell to the device shell to excite the resonant element, where the piezoelectric material is deposited and shaped on the outer cap shell. Using the proposed indirect excitation method, the metal coating of the device shell is eliminated, preserving the high quality factor of the pristine fused quartz material. In this paper, we first introduce the mechanism of excitation, supported by Finite Element Analysis (FEA). We then describe the Atomic Layer Deposition (ALD) method of PbHf <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">˟</inf> Ti <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1-˟</inf> O <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</inf> (PHT) piezoelectric material, followed by the fabrication process of a dual-shell μHRG prototype co-fabricated with an 80 nm layer of ALD PHT actuator. Finally, we experimentally demonstrated the indirect excitation, showing the feasibility of the method as a possible alternative to capacitive or direct piezoelectric actuation. Though early in development, the reported excitation approach may offer a preferable method for excitation of μHRGs, allowing to achieve the ultra-high mechanical quality factor, on the level of the TED-limit of fused quartz.
