Performance Tests for Visual Servo Control Systems, with Application to Partitioned Approaches to Visual Servo Control (2003)

Visual servoing has been a viable method of robot manipulator control for more than a decade. Initial developments involved position-based visual servoing (PBVS), in which the control signal exists in Cartesian space. The younger method, image-based visual servoing (IBVS), has seen considerable development in recent years. PBVS and IBVS offer tradeoffs in performance, and neither can solve all tasks that may confront a robot. In response to these issues, several methods have been devised that partition the control scheme, allowing some motions to be performed in the manner of a PBVS system, while the remaining motions are performed using an IBVS approach. To date, there has been little research that explores the relative strengths and weaknesses of these methods. In this paper we present such an evaluation. We have chosen three recent visual servo approaches for evaluation in addition to the traditional PBVS and IBVS approaches. We posit a set of performance metrics that mea sure quantitatively the performance of a visual servo controller for a specific task. We then evaluate each of the candidate visual servo methods for four canonical tasks with simulations and with experiments in a robotic work cell.
Electrophilic alkynylation of ketones using hypervalent iodine (2014)

A new method for the electrophilic α-alkynylation of ketones was developed using hypervalent iodine under mild and metal-free conditions. Carbonyl compounds containing an α-acetylene group were obtained in good to excellent yields for several ketones using 1-[(trimethylsilyl)ethynyl]-1,2-benziodoxol-3(1H)-one (TMS-EBX) as an alkynylation agent in the presence of t-BuOK and TBAF in THF as solvent. Under the same conditions, an aldehyde was alkynylated.
Effects of different storage solutions on renal ischemia tolerance after kidney transplantation in mice (2017)

storage is the most prevalent method for graft preservation in kidney transplantation (KTX). The protective effects of various preservation solutions have been studied extensively in both clinical trials and experimental animal models. However, a paucity of studies have examined the effect of different preservation solutions on graft function in mouse KTX; in addition, the tolerance of the transplanted grafts to further insult has not been evaluated, which was the objective of the present study. We performed mouse KTX in three groups, with the donor kidneys preserved in different solutions for 60 min: saline, mouse serum, and University of Wisconsin (UW) solution. The graft functions were assessed by kidney injury markers and glomerular filtration rate (GFR). The grafts that were preserved in UW solution exhibited better functions, reflected by 50 and 70% lower plasma creatinine levels as well as 30 and 55% higher plasma creatinine levels in GFR than serum and saline groups, respectively, during the first week after transplants. To examine the graft function in response to additional insult, we induced ischemia-reperfusion injury (IRI) by clamping the renal pedicle for 18 min at 4 wk after KTX. We found that the grafts preserved in UW solution exhibited ~30 and 20% less injury assessed by kidney injury markers and histology than in other two preservation solutions. Taken together, our results demonstrated that UW solution exhibited a better protective effect in transplanted renal grafts in mice. UW solution is recommended for use in mouse KTX for reducing confounding factors such as IRI during surgery.
Cover Picture: Palladium Complexes with Chiral Diphospholane Ligands: Comparative Catalytic Properties and Analysis of (η3‐Allyl)palladium Species (Eur. J. Inorg. Chem. 20/2004) (2004)

Abstract The cover picture shows the low‐temperature 31 P NMR signals and simplified 3D representations of exo and endo isomers of an (η 3 ‐1,3‐diphenylallyl)palladium( II ) complex in which the metal center is coordinated by a chiral xanthene‐derived diphospholane ligand. Such complexes are intermediates in palladium‐catalyzed allylic substitution, and their structures determined by 2D NMR spectroscopy allow for the interpretation of the enantioselectivities of the catalytic process in terms of preferential rotation of the allyl group. Key methyl groups of the chiral ligand that govern this rotation are represented by yellow spheres in the background. Details on these complexes and others and on asymmetric catalysis can be found in the article by J. A. Osborn, L. Barloy et al. on p. 3987 ff. The authors are indebted to Bernard Lafleuriel (CURRI‐Visu) for his help concerning the artwork of the cover picture.
The Translation Centre for the Bodies of the European Union: Purpose and activities (2011)

The Translation Centre for the Bodies of the European Union was established in 1994 to meet the translation needs of the other decentralized Community agencies. It also participates in the Interinstitutional Committee for Translation and Interpretation, which is working to promote collaboration between the services of the various European institutions and agencies and to achieve economies of scale in the translation field.&#13;\nIn this paper, we describe the “raison d‟être” of this agency, which is governed by European public law, with legal personality, and which has its own financial resources constituted by the transfers from the European agencies, offices and institutions in exchange for services provided. We focus on its cooperation with 56 EU institutions and bodies located in 22 European countries, a cooperation which involves a number of linguistic activities in a wide spectrum of subject fields, ranging from drugs and medicines to maritime security or chemicals, education, railways, food safety and intellectual property (through its translation of Community trademarks and designs for its biggest client, the Office for Harmonization in the Internal Market).&#13;\nWe also discuss the terminological activities carried out at the Translation Centre, focusing more specifically on the compilation of terminological glossaries for the Centre‟s clients, as well as on the IATE interinstitutional terminological database.
Intermolecular contributions, filtration effects and composition of the SIFTER signal (2022)

Abstract. To characterise structure and order in the nanometer range, distances between electron spins and their distributions can be measured via dipolar spin-spin interactions by different pulsed electron paramagnetic resonance experiments. Here, for the single frequency technique for refocusing dipolar couplings (SIFTER), the buildup of dipolar modulation signal and intermolecular contributions is analysed for a uniform random distribution of monoradicals and biradicals in frozen glassy solvent by using the product operator formalism for electron spin S = 1/2. A dipolar oscillation artefact appearing at both ends of the SIFTER time trace is predicted, which originates from the weak coherence transfer between biradicals. The relative intensity of this artefact is predicted to be temperature independent, but to increase with the spin concentration in the sample. Different compositions of intermolecular backgrounds are predicted in the case of biradicals and in the case of monoradicals. We compare these predictions to experimental SIFTER traces for nitroxide and trityl monoradicals and biradicals. Our analysis demonstrates a good qualitative match with the proposed theoretical description. The resulting perspectives of quantitative analysis of SIFTER data are discussed.
Finite-level Quantized Iterative Learning Control by Encoding-Decoding Mechanisms (2018)

This paper studies the zero-error tacking problem of finite-level quantized iterative learning control using an encoding-decoding method, where both measurement and actuator side quantization and transmission are considered. In particular, the system output is encoded, quantized, transmitted and decoded in sequence for input updating of the next iteration. Then the generated input is transmitted through networks following the same procedure as the output transmission for plant input updating. The zero-error convergence of the proposed scheme is strictly proved and a numerical simulation is provided to demonstrate the effectiveness of the proposed scheme.

Industrial Relevance of Deep Junctions Produced by Rapid Thermal Processing for Power Integrated Circuits (2007)

An alternative method for creating total vertical junction insulation for power devices is presented. It involves the thermomigration of molten Al/Si. First, the method is theoretically detailed. A full description of the equipment required for this task is then given with special emphasis on the specific characteristics needed. Physical and electrical results are briefly discussed, showing the efficiency of the method in terms of surface consumption and voltage handling capability. Finally, application of thermomigration to a manufacturing environment is considered.

Genotype and Plasma Concentration of Cystatin C in Patients with Late-Onset Alzheimer Disease (2007)

The homozygous CST3A/A genotype confers a risk for AD in Taiwan Chinese. Such an association may be due to the reduced level of cystatin C in the peripheral circulation.
Synthesis of Artificial Ladder-Shaped Polyethers Containing a 6/7 cis-Fused Ring System (2006)

Ladder-shaped tetracyclic and heptacyclic ethers containing a 6/7 cis-fused ring system have been synthesized. The synthesis features convergent coupling of monocyclic building blocks through esterification, ring-closing reaction using a low-valent titanium complex, and hydroxy dithioacetal cyclization. The double reaction strategy enabled expeditious synthesis of the heptacyclic ether in only thirteen steps from the building blocks.
CO Tolerance Improvement of MEA Using Metal Thin Film by Sputtering Method in PEM Fuel Cell (2007)

개질기에서 생산된 수소를 연료전지용 연료로 사용할 때에는 개질수소가 포함하고 있는 일산화탄소가 막-전극접합체의 촉매를 피독시켜서 연료전지 성능이 크게 감소된다. 본 논문에서는 개질수소에 포함된 일산화탄소가 스퍼터링 공정으로 제조된 박막층에 의하여 개선된 막-전극접합체의 성능에 어떠한 영향을 미치는지 연구하였다. 실험결과 Pt와 Ru박막은 MEA의 단위전지 성능을 개선하였으며, 금속박막은 막-전극접합체의 일산화탄소에 대한 내구성을 증가시켰다. 산화전극으로의 공기주입 운전기법은 막-전극접합체의 일산화탄소에 대한 내구성을 증가시켰다. 게다가 Pt, Ru그리고 PtRu박막은 공기주입 운전에 영향을 주는 것으로 확인되었다. When reformer for fuel cell is used, CO in hydrogen gas leads to a seriously decreased membrane electrode assembly (MEA) performance by catalyst poisoning. The effect of CO on performance of modified MEA by sputtering method is studied in this paper. The experimental results show that sputtered Pt and Ru thin film improve a single cell performance of MEA and sputtered metal thin film has a CO tolerance. The air injection process on anode show improved CO tolerance test result. Moreover, Pt, Ru and PtRu thin film by sputtering had influence on the CO tolerance with air injection process.
Involvement of tumor-associated macrophage activationin vitroduring development of a novel mantle cell lymphoma cell line, PF-1, derived from a typical patient with relapsed disease (2014)

Human mantle cell lymphoma (MCL) cell lines are scarce and have been only sporadically described and validated, and only a few have been thoroughly molecularly or genetically characterized. We describe here the successful establishment of a new MCL line, PF-1, with typical MCL characteristics. Culturing primary MCL cells in vitro initially gave rise to an essential generative microenvironment "niche" involving macrophages required for MCL growth, and eventually produced the PF-1 MCL cell line. Our analysis revealed that PF-1 is morphologically and genotypically nearly identical to the original tumor cells. The PF-1 MCL cell line that we have developed will be useful for in vitro and in vivo studies of MCL pathogenesis and therapeutics.

Ontology-based knowledge representation is used not only for the image contents, but also for the complex natural language understanding and dialogue management process. This demo shows a speech-based annotation system for radiology images and focuses on a new and effective way to annotate medical image regions with a specific medical, structured, diagnosis while using speech and pointing gestures on the go.
CD28 expression by mouse mast cells is modulated by lipopolysaccharide and outer surface protein A lipoprotein from Borrelia burgdorferi (1997)

The concept of costimulation has been best defined in T cells and B cells. However, other cells that respond in an Ag-specific fashion, such as the mast cell, may be regulated by similar mechanisms. We have found that murine mast cells express one such costimulatory molecule, CD28, which was previously defined as a T and NK cell-specific protein. While CD28 transcription appeared to be constitutive in murine mast cells, its cell surface expression was not. CD28 cell surface expression by mast cells derived from bone marrow with stem cell factor (SCF) was dependent upon activation with agents such as LPS, the Borrelia burgdorferi lipoprotein outer surface protein A, and PMA. Peak cell surface expression of CD28 by such cells occurred 24 h after LPS stimulation, 18 h after outer surface protein A stimulation, and 3 h after PMA stimulation. In contrast, mast cells derived from bone marrow with IL-3 did not demonstrate induction-specific cell surface expression of CD28. Instead, maturation of such cells in vitro allowed for the increased cell surface expression of CD28. Peritoneal mast cells cultured in SCF also expressed CD28. Mast cell CD28 was functional, in that cross-linking of CD28 on the surface of the IL-3-derived cells resulted in an increased level of c-jun transcripts. Additionally, cross-linking of CD28 simultaneously with PMA treatment of SCF-derived mast cells resulted in an increased level of IL-13 transcripts. These data suggest that mast cell CD28 has functions similar to those of T cell CD28.
Grand Challenge: Applying Regulatory Science and Big Data to Improve Medical Device Innovation (2013)

Understanding how proposed medical devices will interface with humans is a major challenge that impacts both the design of innovative new devices and approval and regulation of existing devices. Today, designing and manufacturing medical devices requires extensive and expensive product cycles. Bench tests and other preliminary analyses are used to understand the range of anatomical conditions, and animal and clinical trials are used to understand the impact of design decisions upon actual device success. Unfortunately, some scenarios are impossible to replicate on the bench, and competitive pressures often accelerate initiation of animal trials without sufficient understanding of parameter selections. We believe that these limitations can be overcome through advancements in data-driven and simulation-based medical device design and manufacturing, a research topic that draws upon and combines emerging work in the areas of Regulatory Science and Big Data. We propose a cross-disciplinary grand challenge to develop and holistically apply new thinking and techniques in these areas to medical devices in order to improve and accelerate medical device innovation.
Metabolic diversification of nitrogen‐containing metabolites by the expression of a heterologous lysine decarboxylase gene in Arabidopsis (2019)

Lysine decarboxylase converts l-lysine to cadaverine as a branching point for the biosynthesis of plant Lys-derived alkaloids. Although cadaverine contributes towards the biosynthesis of Lys-derived alkaloids, its catabolism, including metabolic intermediates and the enzymes involved, is not known. Here, we generated transgenic Arabidopsis lines by expressing an exogenous lysine/ornithine decarboxylase gene from Lupinus angustifolius (La-L/ODC) and identified cadaverine-derived metabolites as the products of the emerged biosynthetic pathway. Through untargeted metabolic profiling, we observed the upregulation of polyamine metabolism, phenylpropanoid biosynthesis and the biosynthesis of several Lys-derived alkaloids in the transgenic lines. Moreover, we found several cadaverine-derived metabolites specifically detected in the transgenic lines compared with the non-transformed control. Among these, three specific metabolites were identified and confirmed as 5-aminopentanal, 5-aminopentanoate and δ-valerolactam. Cadaverine catabolism in a representative transgenic line (DC29) was traced by feeding stable isotope-labeled [α-<sup>15</sup> N]- or [ε-<sup>15</sup> N]-l-lysine. Our results show similar <sup>15</sup> N incorporation ratios from both isotopomers for the specific metabolite features identified, indicating that these metabolites were synthesized via the symmetric structure of cadaverine. We propose biosynthetic pathways for the metabolites on the basis of metabolite chemistry and enzymes known or identified through catalyzing specific biochemical reactions in this study. Our study shows that this pool of enzymes with promiscuous activities is the driving force for metabolite diversification in plants. Thus, this study not only provides valuable information for understanding the catabolic mechanism of cadaverine but also demonstrates that cadaverine accumulation is one of the factors to expand plant chemodiversity, which may lead to the emergence of Lys-derived alkaloid biosynthesis.
Energy value of pig feeds: effect of pig body weight and energy evaluation system. (2004)

Ad libitum energy intake and performance in pigs depends on many animal and environmental factors in which feed energy density plays an important role. In addition, feed represents an important cost in pig production, and energy represents the greatest proportion of this cost. It is therefore important to express the feed energy value on an appropriate basis, and both energy supply (a dietary characteristic) and energy requirement (an animal characteristic) should be expressed using the same system. Energy content depends first on the nutrient composition; the constituents differ markedly in GE content (23.0, 39.0, 17.4, and 18.4 kJ/g for CP, fat, starch, and dietary fiber, respectively). Due to differences in digestibility and associated endogenous energy losses, the actual contribution of nutrients to apparent DE supply in growing pigs is even more variable and ranges from 31.7 kJ/g for fat, 22.4 kJ/g for CP, 17.2 kJ/g for starch, to only 3.2 kJ/g for dietary fiber. Nutrient composition also affects the efficiency of conversion of ME to NE, which varies from 90% for fat to 82% for starch and 60% for CP. Consequently, the energy values (relative to a conventional diet containing 14.2, 13.6, and 10.3 MJ/kg of DE, ME, and NE, respectively) of corn, soybean meal, and animal fat are 100, 104, and 235 on a DE basis; 102, 99, and 244 on a ME basis; and 107, 79, and 289 on a NE basis. Energy value thus depends on the system of evaluation. The energy density of pig feeds can also be affected by feed processing. For example, pelleting markedly increases fat and energy digestibilities in corn or full-fat rapeseed. Also the animal itself can affect the energy value of nutrients; digestion of dietary fiber becomes more efficient with increasing BW, with subsequent differences in energy content of feeds according to BW. In conclusion, a satisfactory characterization of the energy value of feeds should be based on their NE content. Factors affecting nutrients digestibility (e.g., BW and feed processing) should also be taken into account.
Fully-Buffered DIMM Memory Architectures: Understanding Mechanisms, Overheads and Scaling (2007)

Performance gains in memory have traditionally been obtained by increasing memory bus widths and speeds. The diminishing returns of such techniques have led to the proposal of an alternate architecture, the fully-buffered DIMM. This new standard replaces the conventional memory bus with a narrow, high-speed interface between the memory controller and the DIMMs. This paper examines how traditional DDRx based memory controller policies for scheduling and row buffer management perform on a fully-buffered DIMM memory architecture. The split-bus architecture used by FBDIMM systems results in an average improvement of 7% in latency and 10% in bandwidth at higher utilizations. On the other hand, at lower utilizations, the increased cost of serialization resulted in a degradation in latency and bandwidth of 25% and 10% respectively. The split-bus architecture also makes the system performance sensitive to the ratio of read and write traffic in the workload. In larger configurations, we found that the FBDIMM system performance was more sensitive to usage of the FBDIMM links than to DRAM bank availability. In general, FBDIMM performance is similar to that of DDRx systems, and provides better performance characteristics at higher utilization, making it a relatively inexpensive mechanism for scaling capacity at higher bandwidth requirements. The mechanism is also largely insensitive to scheduling policies, provided certain ground rules are obeyed
Evaluation of Diet-Related Infographics on Pinterest for Use of Behavior Change Theories: A Content Analysis (2016)

These findings suggest that current Pinterest infographics targeting healthy eating contain few HBT elements. Health professionals and organizations should create and disseminate infographics that contain more elements of HBT to better influence healthy eating behavior. This may be accomplished by creating pins that use both text and images of people and food in order to portray elements of HBT and convey nutritional information.
