Elektromechanischer Energiewandler basierend auf SOI-Technologie (Electromechanical Energytransducer Based on SOI-Technology) (2007)

In diesem Beitrag wird die Modellierung, Fertigung und Charakterisierung eines elektromechanischen Energiewandlers präsentiert. Dabei werden, sowohl in der Schaltungssimulation des Wandlers als auch in der entspechenden experimentellen Verifikation, der Einfluss des Lastwiderstands sowie die Frequenz und die Amplitude der anregenden Schwingung berücksichtigt. Die für diese Studie realisierten Wandler basieren auf kapazitiven Kammstrukturen aus zwei feststehenden Kammelektroden und einem über freitragende Balken beweglich gelagertem Gegenstück. Neben einem makroskopischen Modell wurden mikromechanische Resonatoren zur Verifikation der theoretischen Vorhersagen realisiert. Der für den miniaturisierten Wandler entwickelte Fertigungsprozess basiert auf „Silicon-on-insulator”-Wafern, deren aktive Siliziumschicht mithilfe von reaktivem Tiefenätzen strukturiert wurde.
Radiation properties of an omnidirectional planar microstrip antenna (2007)

Abstract The pattern and directivity of an ideal omnidirectional antenna, collinear coaxial, and omnidirectiontal microstrip antenna (OMA) are compared. The radiation of an OMA originates from the arraying of two radiating edges along each element. The width of the (OMA) elements determines omni‐plane pattern variation. © 2007 Wiley Periodicals, Inc.

Direct detection of free radicals in the reperfused rat heart using electron spin resonance spectroscopy. (1987)

The purpose of this study was to use a direct method, that of electron spin resonance (ESR) spectroscopy, to demonstrate that reperfusion after a period of ischemia results in a sudden increase in the production of free radicals in the myocardium. The isolated buffer-perfused rat heart was used with N-tert-butyl-alpha-phenylnitrone (PBN) as a spin-trapping agent. Samples of coronary effluent were taken and extracted into toluene for detection of radical adducts by ESR spectroscopy. After 15 minutes of total, global ischemia, aerobic reperfusion resulted in a sudden burst of radical formation that peaked at 4 minutes. When hearts were reperfused with anoxic buffer, no dramatic increase in radical production was observed. Subsequent reintroduction of oxygen, however, resulted in an immediate burst of radical production of a similar magnitude to that seen in the wholly aerobic reperfusion experiments. The ESR signals obtained (aN = 13.60 G, aH = 1.56 G) are consistent with the spin-trapping by PBN of either a carbon-centered species or an alkoxyl radical, both of which could be formed by secondary reactions of initially-formed oxygen radicals with membrane lipid components.
Mechanism of diethyldithiocarbamate, dihydroxyethyldithiocarbamate, and dicarboxymethyldithiocarbamate action of distribution and excretion of cadmium. (1984)

Diethyldithiocarbamate (DEDC), dihydroxyethyldithiocarbamate (DHDC), and dicarboxymethyldithiocarbamate (DCDC) were assessed for their relative efficacies in mobilizing metallothionein-bound cadmium (Cd) from selected organs and tissues of mice and in promoting Cd excretion. The DHDC was effective but less so than DEDC in mobilizing Cd from liver, kidney and spleen. However, while DEDC effected a redistribution of Cd which resulted in higher levels in lungs, testes, heart, and brain, DHDC after 13 injections reduced the levels of Cd in all four of these organs. The DCDC analog did not alter the Cd load of any organ. Bone Cd content was most effectively reduced by DEDC; DCDC was somewhat less active, and DCDC was without effect. Skin Cd burden was enhanced markedly after treatment with DEDC but was reduced by treatment with DHDC or DCDC. Treatment with DEDC increased the muscle Cd content about 250 percent over control values; treatment with DHDC reduced it significantly, while DCDC was without effect. Both DEDC and DHDC reduced the whole body Cd burden, but DCDC was ineffective. The initial rate of fecal excretion of Cd was much greater following DHDC treatment than after DEDC treatment, while DCDC did not promote excretion to any detectable extent. The pattern of mobilization, redistribution, and excretion of Cd following treatment with each chelator was related to the organic/aqueous partition coefficient of each dithiocarbamate-Cd complex.
Light-induced dangling bonds in hydrogenated amorphous silicon (1981)

After intensive and long illumination of undoped a-Si:H samples the dark ESR signal is considerably enhanced. The g value of 2.0055 and the linewidth DHpp = 6–7 G leads to the conclusion that the light-induced defects are single dangling bonds. They disappear again by thermal anneal at about 220 °C.
MECHANISMS INVOLVED IN ANTITHYMOCYTE GLOBULIN IMMUNOSUPPRESSIVE ACTIVITY IN A NONHUMAN PRIMATE MODEL 1 (2001)

The results indicate that T-cell depletion is achieved rapidly and primarily in peripheral lymphoid tissues at high ATG dosage. Short ATG treatments could therefore be clinically evaluated when major peripheral T-cell depletion is required.
Adverse Hemodynamic Effects of Interrupting Chest Compressions for Rescue Breathing During Cardiopulmonary Resuscitation for Ventricular Fibrillation Cardiac Arrest (2001)

Interrupting chest compressions for rescue breathing can adversely affect hemodynamics during CPR for VF.
RABIT: a new framework for runtime emulation and binary translation (2004)

Binary translation has been widely used as object code migration across different architectures. Most current works are targeted towards running an existing (old architecture) binary version of a complex application on a newer architecture and so availability of resources is not a problem. In this paper we propose a technique called RABIT for emulating a newer architecture's binary on an older one. RABIT will allow the consumers to emulate the applications developed for newer hardware on their older machines by incurring some performance trade-offs. This way the needy consumers can take advantage of the newer software features on their existing machines before they decide to upgrade them to later models. In situations where the newer hardware is in place, our technique can be used to run applications redundantly on the older machine for dependability analysis. It also provides the CPU architects with an instruction-level simulator to test the design and stability of a new CPU before the new hardware is actually in place. RABIT's design consists of a translator, an interpreter and a set of operating system services. To deal with the less amount of resources like registers in the older architecture as compared to the newer ones, we present a new register allocation algorithm. The feasibility of the technique is established by simulating RABIT for its performance.

Nutritional Outputs and Energy Inputs in Seafoods (1977)

Energy used by U.S. ships in harvesting seafoods can vary by a factor of more than 100 when the seafoods are compared on the basis of their content of edible protein or line weight. This energy difference bears no relationship to the nutritive value in the food. When protein yield is compared, the energy to harvest some seafoods is in the same range as that needed to grow field crops. There is a large increase in energy consumption after processing, partly because of the small percent of the live weight used for human food.
Identification and Inheritance of Inefficient Zinc Absorption in Soybean (1991)

Two experimental soybean [ Glycine max (L.) Merr.] lines that had produced nearly similar seed yields when grown at Stoneville, MS, differed widely when grown at Newton, MS. This study was conducted to identify the cause for the low seed yield of one line at Newton. Previous studies at this location on soils limed to a pH of 7.0 had shown that ‘Forrest’ soybean increased in yield when fertilized with zinc. Data are not available to show that soybean genotypes differ in efficiency of Zn absorption, so studies were initiated to determine whether Zn concentration in the foliage was different between the two experimental soybean lines. Fully developed trifoliolate leaves were taken from the upper part of the plant at the R1 growth stage and analyzed for concentration of Zn. The low‐yielding line D82‐3298 contained 18 to 25 μg g ‐1 of Zn, while D77‐6056, the high yielding line, had 48 to 56 μg g ‐1 of Zn. These results indicated that the two did differ in efficiency of Zn absorption. Three hundred thirty F3 lines from the cross D77‐6056 × D82‐3298 were grown along with parents in the same area the following year. The mean Zn concentration for the parental lines was 18.8 ±; 1 μg ‐l for D82‐3298 and 36.9 ± 2.6 μg g ‐1 for D77‐6056. The distribution of F 3 lines for Zn concentration suggests that only a few genes control Zn absorption efficiency or inefficiency. In additional plantings, D82‐3298, D77‐6056, and Forrest were grown with and without Zn fertilization. D82‐3298 gave a significant ( P < 0.05) increase in foliar Zn concentration and seed yield when fertilized with ZnSO 4 at Newton, but not at Stoneville. D77‐6056 and Forrest gave no response at either location.
Synergistic Competitive Inhibition of Ferrous Iron Oxidation by <i>Thiobacillus ferrooxidans</i> by Increasing Concentrations of Ferric Iron and Cells (1989)

Oxidation of ferrous iron by Thiobacillus ferrooxidans SM-4 was inhibited competitively by increasing concentrations of ferric iron or cells. A kinetic analysis showed that binding of one inhibitor did not exclude binding of the other and led to synergistic inhibition by the two inhibitors. Binding of one inhibitor, however, was affected by the other inhibitor, and the apparent inhibition constant increased with increasing concentrations of the other inhibitor.
[The genetic aspects of the study of Pseudomonas syringae bacteria]. (1995)

The work is a review of the state-of-art of molecular-genetic examination of bacteria P. syringae. The questions concerning new approaches to the study of determinants of pathogenicity, endogenic plasmids, toxins, resistance to antibiotics, avirulence, genes and insertion sequence elements of P. syringae are stated.
New Processes for Surface Treatment of Catheters (1994)

Infection, thrombosis, and stenosis are among the most common complications of blood-contacting catheters and are caused by surface properties of the substrate materials. Ion beam-based processes such as ion implantation and ion beam-assisted deposition affect only the outer micron of the treated material surface; there is little effect on bulk properties. These processes were therefore used on common catheter materials, and their biological properties were evaluated. Ion implantation of materials such as silicone rubber resulted in a less tacky, more wettable surface that demonstrated thrombus-resistance in both in vivo and preliminary clinical studies. Ion beam-assisted deposition was used to deposit silver-based coatings, which demonstrated antimicrobial activity in in vitro and clinical studies. Biocompatibility of these processed catheter materials was also demonstrated using simple laboratory studies. These processes, therefore, can be readily applied to blood-contacting catheters to make them thrombus- and infection-resistant.
Structure-Based Design of HIV Protease Inhibitors:  5,6-Dihydro-4-hydroxy-2-pyrones as Effective, Nonpeptidic Inhibitors (1996)

From a broad screening program, the 4-hydroxycoumarin phenprocoumon (I) was previously identified as a lead template with HIV protease inhibitory activity. The crystal structure of phenprocoumon/HIV protease complex initiated a structure-based design effort that initially identified the 4-hydroxy-2-pyrone U-96988 (II) as a first-generation clinical candidate for the potential treatment of HIV infection. Based upon the crystal structure of the 4-hydroxy-2-pyrone III/HIV protease complex, a series of analogues incorporating a 5,6-dihydro-4-hydroxy-2-pyrone template were studied. It was recognized that in addition to having the required pharmacophore (the 4-hydroxy group with hydrogen-bonding interaction with the two catalytic aspartic acid residues and the lactone moiety replacing the ubiquitous water molecule in the active site), these 5,6-dihydro-4-hydroxy-2-pyrones incorporated side chains at the C-6 position that appropriately extended into the S1' and S2' subsites of the enzyme active site. The crystal structures of a number of representative 5,6-dihydro-4-hydroxy-2-pyrones complexed with the HIV protease were also determined to provide better understanding of the interaction between the enzyme and these inhibitors to aid the structure-based drug design effort. The crystal structures of the ligands in the enzyme active site did not always agree with the conformations expected from experience with previous pyrone inhibitors. This is likely due to the increased flexibility of the dihydropyrone ring. From this study, compound XIX exhibited reasonably high enzyme inhibitory activity (Ki = 15 nM) and showed antiviral activity (IC50 = 5 microM) in the cell-culture assay. This result provided a research direction which led to the discovery of active 5,6-dihydro-4-hydroxy-2-pyrones as potential agents for the treatment of HIV infection.
Outlier elimination for robust ellipse and ellipsoid fitting (2009)

In this paper, an outlier elimination algorithm for ellipse/ellipsoid fitting is proposed. This two-stage algorithm employs a proximity-based outlier detection algorithm (using the graph Laplacian), followed by a model-based outlier detection algorithm similar to random sample consensus (RANSAC). These two stages compensate for each other so that outliers of various types can be eliminated with reasonable computation. The outlier elimination algorithm considerably improves the robustness of ellipse/ellipsoid fitting as demonstrated by simulations.

WE SHOULD PERSUADE IRAN WITH BARGAINS NOT BOMBS (2006)

Iran’s defiance of the IAEA has raised questions about Tehran’s desire to build nuclear weapons and this in turn has put that country squarely into the cross-hairs of the hawks in Washington. This case study reflects my search to answer a logical question stemming from the current backdrop; should we bomb Iran in order to prevent Tehran from obtaining nuclear weapons? I am a U.S. Marine Corps combat veteran from the first gulf war where I acted as an Iranian linguist signals intelligence and crypto-logic technician. It is impossible for me not to be passionate about our policies in the Middle East. My interpretation of this research tells me that the United States should begin direct communications with Iran. The social and behavioral sciences play a huge role in determining a policy outcome. Predicting how Iran and the rest of the world will react to our actions is of great importance. Just as a chess player tries to look at every future move, so to do we need a predictable strategy. This study will express the reasoning I have used to arrive at my claim that we should try to persuade Iran away from building nuclear weapons with bilateral talks and bargains not bombs. We, the United States, have not had a diplomatic relationship with Iran since the revolution in 1979. Twenty-seven years of not communicating. That is a long time to hold a grudge. In essence, I have discovered that now is the time to “burry the hatchet”.
Modeling mention, context and entity with neural networks for entity disambiguation (2015)

Given a query consisting of a mention (name string) and a background document, entity disambiguation calls for linking the mention to an entity from reference knowledge base like Wikipedia. Existing studies typically use hand-crafted features to represent mention, context and entity, which is laborintensive and weak to discover explanatory factors of data. In this paper, we address this problem by presenting a new neural network approach. The model takes consideration of the semantic representations of mention, context and entity, encodes them in continuous vector space and effectively leverages them for entity disambiguation. Specifically, we model variable-sized contexts with convolutional neural network, and embed the positions of context words to factor in the distance between context word and mention. Furthermore, we employ neural tensor network to model the semantic interactions between context and mention. We conduct experiments for entity disambiguation on two benchmark datasets from TAC-KBP 2009 and 2010. Experimental results show that our method yields state-of-the-art performances on both datasets.
Camera geometries for image matching in 3-D machine vision (1989)

The location of a scene element can be determined from the disparity of two of its depicted entities (each in a different image). Prior to establishing disparity, however, the correspondence problem must be solved. It is shown that for the axial-motion stereo camera model the probability of determining unambiguous correspondence assignments is significantly greater than that for other stereo camera models. However, the mere geometry of the stereo camera system does not provide sufficient information for uniquely identifying correct correspondences. Therefore, additional constraints derived from justifiable assumptions about the scene domain and from the scene radiance model are utilized to reduce the number of potential matches. The measure for establishing the correct correspondence is shown to be a function of the geometrical constraints, scene constraints, and scene radiance model.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Continuous Steam Quality Measurement in a Steam Distribution System Quality Measurement (1987)

ABSTRACT In an effort to provide accurate, reliable data on steam distribution, 67 continuous steam injection wells on Santa Fe Energy Company's steam flood project in the Kern River Field were equipped with steam quality meters using vibrating densitometer principles combined with flowmeters and microprocessors for continuous monitoring of temperature, quality, mass flow rate and energy content. Although equipment limitations were encountered, techniques for validating steam quality measurements and flow rates by overall system mass balance were developed. Instrumentation of the type employed in the project combined with the centralized processing of the data from each individual injection well is a new tool for optimizing steam distribution and injection documentation for reservoir modeling.
Endothelial colony-forming cells from patients with chronic myeloproliferative disorders lack the disease-specific molecular clonality marker (2009)

Two putative types of circulating endothelial progenitor cells have been recently identified in vitro: (1) endothelial colony-forming cell (ECFC) and (2) colony-forming unit-endothelial cell (CFU-EC). Only the former is now recognized to belong to endothelial lineage. We have used the ECFC and CFU-EC assays to readdress the issue of the clonal relation between endothelial progenitor cells and hematopoietic stem cells in patients with Philadelphia-positive and Philadelphia-negative chronic myeloproliferative disorders. Both ECFCs and CFU-ECs were cultured from peripheral blood mononuclear cells, and either BCR-ABL rearrangement or JAK2-V617F mutation were assessed in both types of endothelial colonies. We found that ECFCs lack the disease-specific markers, which are otherwise present in CFU-ECs, thus reinforcing the concept that the latter belongs to the hematopoietic lineage, and showing that in chronic myeloproliferative disorders the cell that gives rise to circulating ECFC has a distinct origin from the cell of the hematopoietic malignant clone.
