Balancing Interactive Performance and Budgeted Resources in Mobile Computing. (2014)

In this dissertation, we explore the various limited resources involved in mobile applications --- battery energy, cellular data usage, and, critically, user attention --- and we devise principled methods for managing the tradeoffs involved in creating a good user experience. Building quality mobile applications requires developers to understand complex interactions between network usage, performance, and resource consumption. Because of this difficulty, developers commonly choose simple but suboptimal approaches that strictly prioritize performance or resource conservation. These extremes are symptoms of a lack of system-provided abstractions for managing the complexity inherent in managing performance/resource tradeoffs. By providing abstractions that help applications manage these tradeoffs, mobile systems can significantly improve user-visible performance without exhausting resource budgets. This dissertation explores three such abstractions in detail. We first present Intentional Networking, a system that provides synchronization primitives and intelligent scheduling for multi-network traffic. Next, we present Informed Mobile Prefetching, a system that helps applications decide when to prefetch data and how aggressively to spend limited battery energy and cellular data resources toward that end. Finally, we present Meatballs, a library that helps applications consider the cloudy nature of predictions when making decisions, selectively employing redundancy to mitigate uncertainty and provide more reliable performance. Overall, experiments show that these abstractions can significantly reduce interactive delay without overspending the available energy and data resources.

Improving the outcoupling efficiency of indium-tin-oxide-free organic light-emitting diodes via rough internal interfaces (2010)

We present low-cost texturing methods to produce different surface roughnesses on glass substrates. Using sand blasting, abrasion and wet etching we achieve roughnesses of about 50 nm to 250 nm (root mean squared roughness Rq). These textured substrates are used as extraction elements for guided modes and substrate modes in organic light-emitting diodes (OLEDs). We evaporate 50 nm of the high index material Ta₂O₅ on the textured substrate, which acts as waveguide layer, and flatten it with the transparent photoresist SU-8. On top of that, we fabricate indium tin oxide (ITO)-free OLEDs, which are characterized by electroluminescence and photoluminescence measurements. The devices with rough interfaces obtain an up to 37.4% and 15.5% (at 20 mA/cm²) enhanced emission and it is shown that the enhancement is due to an increased outcoupling efficiency.
Can a Robot's Touches Express the Feeling of Kawaii toward an Object? (2020)

Kawaii, a Japanese word that means "cute," is an essential design concept in consumer and pop culture in Japan. In this study, we focused on a situation where a social robot describes an object during an information-providing task, which is commonly required for social robots in daily environments. Since past studies reported kawaii feelings are associated with a motivation to approach a target, our robot expressed feelings of kawaii to objects touch behaviors. We also focused on whether touch behaviors that emphasize style increase the feeling of kawaii of the touched object, following a phenomenon where people strongly touch a target when they overwhelmingly feel positive emotion: cute aggression. Our experimental results showed the effectiveness of touch behaviors to express the feelings of kawaii from the robot toward objects and to increase the participants' feelings of kawaii toward the object. We identified fewer effects from the participants to the robot. The emphasized motion style did not show any significant effects for the kawaii feelings.
Optimal design of low-pass filters using open stubs to control the out-of-band (2000)

This paper reports on a new synthesis of low-pass filter using open-circuited stubs, leading to the improvement of the out-of-band response. In this purpose, additional technological parameters are introduced. This leads to an optimal choice of both of the length and characteristic impedance of the different elements constituting the filter, depending on the involved technology characteristics. The proposed synthesis is validated by experimental results.
Simulation of oxygen saturation measurement in a single blood vein (2016)

The value of oxygen saturation in venous blood, SvO<sub>2</sub>, has important clinical significance since it is related to the tissue oxygen utilization, which is related to the blood flow to the tissue and to its metabolism rate. However, existing pulse oximetry techniques are not suitable for blood in veins. In the current study we examine the feasibility of difference oximetry to assess SvO<sub>2</sub> by using two near-infrared wavelengths and collecting the backscattered light from two photodetectors located at different distances from the light source.
Identification, quantitation and sensory evaluation of methyl 2- and methyl 3-methylbutanoate in varietal red wines (2015)

Background and Aims Esters are the most important class of volatile compounds contributing to fruity and berry-like aroma notes in wine. In this study, we identified aroma-active compounds in Carmenere red wine with a focus on fruity smelling compounds. Methods and Results Application of an aroma extract dilution analysis to an aroma isolate obtained from Carmenere red wine by solvent-assisted flavour evaporation revealed, apart from well-known wine aroma compounds, two additional fruity smelling compounds, which were identified as methyl 2-methylbutanoate (M2MB) and methyl 3-methylbutanoate (M3MB). Quantitation of M2MB and M3MB in 16 different varietal red wines by stable isotope dilution assays resulted in a concentration below (M2MB) and close to or slightly above (M3MB) the respective odour threshold values. Spiking experiments based on a synthetic wine aroma model in combination with triangle tests did not result in significant sensory differences. Conclusions Methyl 2-methylbutanoate and M3MB are two novel volatile compounds that were identified in all red varietal wines. At the concentration found, they do not contribute significantly to the fruity aroma of these red wines. Significance of the Study This is the first report on the occurrence, concentration and sensory impact of M2MB and M3MB in red wines.

Two Early Nodulation Genes are not Markers for the Capacity of Leguminous Nursery Crops to Form Root Nodules (1999)

Abstract Little is known about mechanisms that permit or prevent formation of root nodules in which nitrogen gas (N 2 ) is fixed by rhizobial bacteria in association with nursery crops in the legume family. We tested the hypothesis that two genes associated with the fixation of N 2 could be used as markers of nodulation capacity among legumes because they occur only in species that can form functional nodules. The presence of ENOD2 and ENOD12 was tested in genomic DNA from three non-nodulating legumes [ Cercis canadensis L. (eastern redbud), Gleditsia triacanthos L. var. inermis Willd. (thornless honeylocust), Gymnocladus dioicus (L.) K. Koch (Kentucky coffeetree)] and two nodulating legumes [ Albizia julibrissin Durazz. (silk-tree), Laburnum alpinum (Mill.) Bercht. &amp; Presl. (Scotch laburnum)]. Southern analyses indicated that ENOD2 is present in thornless honeylocust, Kentucky coffeetree, and Scotch laburnum, and that ENOD12 is present in eastern redbud, thornless honeylocust, and Scotch laburnum. These results diversify the group of nodulating legumes in which ENOD2 and ENOD12 have been found and show these genes also occur in legumes considered incapable of nodulation. We conclude that neither gene can be used to screen existing or new leguminous nursery crops for the capacity to form N 2 -fixing nodules.
Design, Synthesis, and Evaluation of a Dye Library: Glass-Forming and Solid-State Luminescent Merocyanines for Functional Materials (1999)

A highly efficient multicomponent reaction based on the little-known formylating agent dimethylformamide in acetic anhydride led to a multitude of dyes of the indoline (1) and of the thiazole type (2), whose systematic evaluation revealed desired and surprising solid-state properties.
Digital-to-Analog Hardware Trojan Attacks (2021)

We propose a Hardware Trojan (HT) attack for analog circuits with its key characteristic being that it cannot be prevented or detected in the analog domain. The HT attack works in the context of Systems-on-Chip (SoCs) comprising both digital and analog Intellectual Property (IP) blocks. The attacker could be either the SoC integrator or the foundry. More specifically, the HT trigger is placed inside a dense digital IP block where it can be effectively hidden, whereas the HT payload is in the form of a digital pattern transported via the test bus or generated within the test bus, reaching the Design-for-Test (DfT) or programmability interface of the victim analog IP with the test bus. The HT payload unexpectedly activates the DfT and sets the victim analog IP into some possibly partial and undocumented test mode or changes the nominal programmability. The HT payload can be designed to result in performance degradation or complete malfunction, i.e., denial of service. We demonstrate this HT attack scenario on two analog IPs, namely a low-dropout (LDO) regulator using simulation and an RF receiver using hardware measurements.
New molecular approach for the detection of Kinetoplastida parasites of medical and veterinary interest (2019)

<title>Abstract</title> Background Kinetoplastids are a remarkable group of protists, containing a range of ubiquitous free-living species–pathogens of invertebrates, vertebrates and even some plants. Trypanosoma species cause sleeping sickness and Chagas disease, whereas the leishmaniases kill and debilitate hundreds of thousands of people worldwide. The diagnosis of a series of pathogenic kinetoplastids is based on clinical manifestations, epidemiological and laboratory data and, for laboratory methods, a gold standard is often missing for human or animal patients. The aim of this study was to implement a molecular approach for the diagnosis and study of Kinetoplastida. Methods The TaqMan qPCR assays targeting: the 24Sa LSU for Kinetoplastida, 28S LSU for Leishmania/ Trypanosoma spp., 5.8S rRNA for Trypanosoma spp., 18S SSU for Leishmania spp., Kinetoplast minicircle DNA (kDNA) L. donovani complex and the L. infantum specific qPCR were designed, validated for their sensitivity and specificity in silico and then in vitro using a panel of known DNAs and after that they were used in the screening of 369 blood samples (358 dogs, 2 equids, 9 monkeys) . In addition, the new 28S LSU primer sets are presented for use in Kinetoplastida's identiﬁcation by PCR and sequencing. Results All qPCR assays showed high analytical sensitivities without failures. They detect about 0.01 parasite/ mL blood for the kDNA based qPCR and at least a single cell-equivalent of rDNA for the other systems. Based on the sequencing results, after screening, sensitivity (Se) and specificity (Sp) were: 0. 919 and 0.971, 0.853 and 0.979, 1.00 and 0.987, 0.826 and 0.995 for all of Kinetoplastida, Leishmania/ Trypanosoma, Trypanosoma, Leishmania spp. specific qPCRs, respectively. kDNA based qPCRs were more sensitive and specific (Se: 1.00; Sp: 0.997). PCR and sequencing allowed the detection of Kinetoplastids in animal blood samples such as: L. infantum, L. guyanensis, T. congolense, T. evansi and Bodo spp.. Conclusion The molecular approach proposed in this study is useful in epidemiological studies, in fundamental research such as screening for new Kinetoplastida species, in diagnosis and therapeutic follow-up. In addition, researchers are free to choose the molecular tools adapted to their studies.
Developmental appearance and ultrastructural immunolocalization of a major 66 kDa phosphoprotein in embryonic and post‐natal chicken bone (1990)

Biochemical analyses and immunocytochemistry were used to examine the developmental appearance of a major approximately 66 kDa bone phosphoprotein (66 kDa BPP) in the mid-diaphyseal region of embryonic and post-natal chicken tibiae in vivo. Total protein and O-phosphoserine (Ser-P) and O-phosphothreonine (Thr-P) content of 8-, 12-, and 18-day embryonic, and 4-wk post-natal chicken tibiae were determined by amino acid analysis. Similar bone samples were carried through a wide variety of tissue-processing regimes including different protocols for fixation, decalcification, dehydration, and embedding prior to electron microscopy. For immunocytochemistry, tissue sections were incubated with a polyclonal antibody raised in rabbits against 66 kDa BPP, and the antigen was revealed by the high-resolution protein A-gold technique. Amino acid analysis, Western blotting, and immunocytochemistry all showed the presence and increasing concentration of bone phosphoprotein with advancing developmental age. Immunogold labeling was observed over osteoblasts and mineral deposits throughout the bone with the most intense reaction occurring at the mineralization front in embryonic tibiae. Electron probe X-ray microanalysis confirmed the association of 66 kDa BPP with mineral. The levels of phosphoprotein in the tissue were directly correlated with increasing degrees of mineralization. These observations are consistent with previous proposals suggesting that phosphoproteins may play a significant role in the calcification of bone matrix.
Control of FEL Radiation by Tailoring the Seed Pulses (2018)

Seeded free-electron lasers (FELs) produce intense, ultrashort and fully coherent X-ray pulses. These seeded FEL pulses depend on the initial seed properties. Therefore, controlling the seed laser allows tailoring the FEL radiation for phase-sensitive experiments. In this contribution, we present detailed simulation studies to characterize the FELprocess and to predict the operation performance of seeded pulses. In addition, we show experimental data on the temporal characterization of the seeded FEL pulses performed at the sFLASH experiment in Hamburg.
Differential Roles of Macrophages in Diverse Phases of Skin Repair (2010)

Influx of macrophages plays a crucial role in tissue repair. However, the precise function of macrophages during the healing response has remained a subject of debate due to their functional dichotomy as effectors of both tissue injury and repair. We tested the hypothesis that macrophages recruited during the diverse phases of skin repair after mechanical injury exert specific functions to restore tissue integrity. For this purpose, we developed a mouse model that allows conditional depletion of macrophages during the sequential stages of the repair response. Depletion of macrophages restricted to the early stage of the repair response (inflammatory phase) significantly reduced the formation of vascularized granulation tissue, impaired epithelialization, and resulted in minimized scar formation. In contrast, depletion of macrophages restricted to the consecutive mid-stage of the repair response (phase of tissue formation) resulted in severe hemorrhage in the wound tissue. Under these conditions, transition into the subsequent phase of tissue maturation and wound closure did not occur. Finally, macrophage depletion restricted to the late stage of repair (phase of tissue maturation) did not significantly impact the outcome of the repair response. These results demonstrate that macrophages exert distinct functions during the diverse phases of skin repair, which are crucial to control the natural sequence of repair events.
Heat Release in Turbine Cooling II: Numerical Details of Secondary Combustion Surrounding Shaped Holes (2011)

Film cooling plays a critical role in providing effective thermal protection to components in modern gas turbine engines. Most of the previous studies on film cooling were conducted using either cylindrical or shaped coolant holes with nonreactive pure gases in the cross-stream flow. In this paper, the chemically reactive film cooling over a surface with shaped coolant hole is investigated by a Reynolds-averaged Navier–Stokes approach with a shear-stress transport k-!model to simulate the turbulentflow.To take into account the secondary combustion resulting from the unburned fuels in the crossflow, a two-step reaction scheme was used for the combustion of propane. An eddydissipation concept approach was used to account for the turbulence–chemistry interaction. The three-dimensional simulation was performed on an unstructured hybrid grid. The characteristics of reactive thermal flows, jet– crossflow interactions, species transport, and fuel consumption were investigated at different equivalence ratios and blowing ratios. Numerical results provide insight into where reactions take place and how fuel is consumed.
Injection-Molded Microfluidic Device for SERS Sensing Using Embedded Au-Capped Polymer Nanocones (2018)

To enable affordable detection and diagnostic, there is a need for low-cost and mass producible miniaturized sensing platforms. We present a fully polymeric microfluidic lab-on-a-chip device with integrated gold (Au)-capped nanocones for sensing applications based on surface-enhanced Raman spectroscopy (SERS). All base components of the device were fabricated via injection molding (IM) and can be easily integrated using ultrasonic welding. The SERS sensor array, embedded in the bottom of a fluidic channel, was created by evaporating Au onto IM nanocone structures, resulting in densely packed Au-capped SERS active nanostructures. Using a Raman active model analyte, trans-1,2-bis-(4-pyridyl)-ethylene, we found a surface-averaged SERS enhancement factor of ∼5 × 10<sup>6</sup> with a relative standard deviation of 14% over the sensor area (2 × 2 mm<sup>2</sup>), and a 18% signal variation among substrates. This reproducible fabrication method is cost-effective, less time consuming, and allows mass production of fully integrated polymeric, microfluidic systems with embedded high-density and high-aspect ratio SERS sensor.

Vernalization-induced flowering in cereals is associated with changes in histone methylation at the <i>VERNALIZATION1</i> gene (2009)

Prolonged exposure to low temperatures (vernalization) accelerates the transition to reproductive growth in many plant species, including the model plant Arabidopsis thaliana and the economically important cereal crops, wheat and barley. Vernalization-induced flowering is an epigenetic phenomenon. In Arabidopsis, stable down-regulation of FLOWERING LOCUS C (FLC) by vernalization is associated with changes in histone modifications at FLC chromatin. In cereals, the vernalization response is mediated by stable induction of the floral promoter VERNALIZATION1 (VRN1), which initiates reproductive development at the shoot apex. We show that in barley (Hordeum vulgare), repression of HvVRN1 before vernalization is associated with high levels of histone 3 lysine 27 trimethylation (H3K27me3) at HvVRN1 chromatin. Vernalization caused increased levels of histone 3 lysine 4 trimethylation (H3K4me3) and a loss of H3K27me3 at HvVRN1, suggesting that vernalization promotes an active chromatin state at VRN1. Levels of these histone modifications at 2 other flowering-time genes, VERNALIZATION2 and FLOWERING LOCUS T, were not altered by vernalization. Our study suggests that maintenance of an active chromatin state at VRN1 is likely to be the basis for epigenetic memory of vernalization in cereals. Thus, regulation of chromatin state is a feature of epigenetic memory of vernalization in Arabidopsis and the cereals; however, whereas vernalization-induced flowering in Arabidopsis is mediated by epigenetic regulation of the floral repressor FLC, this phenomenon in cereals is mediated by epigenetic regulation of the floral activator, VRN1.
Stitching-free 3D printing of millimeter-sized highly transparent spherical and aspherical optical components (2021)

High-throughput differentiated service provision router architecture for wireless network-on-chip (2012)

This paper proposes a QoS-aware wireless network-on-chip architecture that not only enables quality-oriented network transmission with a feasible implementation overhead but also maintains well-balanced workload inside the hybrid networks to enhance system throughput. Transmission differentiation allows guaranteed service provision and realises network resource optimisation. The advanced routers employ congestion management which first grants high priority packets from more congested areas and then directs them to paths without contention. Adaptive load-balanced routing effectively relaxes congestion situations and prevents networks from worse contention. Simulation results show that average latency of high priority is significantly improved. Flexible buffer management further improves transmission performance and resource utilisation efficiency. The generality for the proposed router architecture has been demonstrated from various traffic patterns. Feasibility evaluation shows negligible cost overhead and demonstrates its practicality.
