Low-Profile Design of Metasurface Considering FSS Filtering Characteristics (2012)

This paper describes a metasurface designed utilizing either a Frequency Selective Surface (FSS) that has band-pass characteristics or one with band-rejection filtering characteristics in order to clarify the relationship between the filtering characteristics of the FSS and the Perfect Magnetic Conductor (PMC) characteristics of the metasurface. The effects of the filtering characteristics of the FSS on the PMC characteristics of the metasurface are described. Calculation results confirm that a low profile metasurface can be achieved using these FSSs. In addition, the effects of the size of the metasurface on the PMC characteristics of the surface are shown.
Abdominal Wall Closure With a Silastic Patch After Repair of Congenital Diaphragmatic Hernia (2004)

Because of the high survival rate and the complication-free rapid healing of the abdominal wall, the technique can be used in any case of CHD in which tension-free closure of the abdominal wall cannot be achieved by other methods.
Synthesis and Properties of Novel Magnetorheological Fluids Having Improved Stability and Redispersibility (1999)

A novel class of relatively stable and redispersible MR fluids based on meso-scale magnetic particles of iron or nickel zinc ferrite and nano-scale additives is described. For a flux density B ~ 1 Tesla, the iron based MR fluids exhibited yield stresses of ~100 kPa. For ferrite based fluids the yield stress values were as high as ~15 kPa at B ~ 1T. The yield stresses at the flux density required for magnetic saturation increase quadratically with the saturation magnetization of the particulate material, in good agreement with a model for the yield stress of uniformly saturated particle chains. At lower flux densities, the yield stress was generally observed to increase as B 3/2 , consistent with models of the role of local saturation of the particle magnetization. The additives were found to enhance the stability and redispersibility of the MR fluids: they appeared to promote a small non-zero yield stress in the absence of a field but were found not to have a substantial effect on the field-dependent yield stresses.
Field induced dynamic waveguides based on potassium tantalate niobate crystals (2012)

In this paper, a new type of optical waveguide based on potassium tantalate niobate (KTN) electro-optic crystal is presented. The guiding property of the optical waveguide can be quickly (on the order of nanosecond) tuned and controlled by the applied external electric field, which can be useful for many applications such as broadband ultrafast optical modulators, variable optical attenuators, and dynamic gain equalizers.
Direct electrochemistry of two genetically distinct flavodoxins isolated from <i>Azotobacter chroococcum</i> grown under nitrogen-fixing conditions (1991)

Two genetically distinct flavodoxins, designated AcFldA and AcFldB, were isolated from Azotobacter chroococcum (MCD1155) grown under nitrogen-fixing conditions. AcFldA and AcFldB differ in their midpoint potentials for the semiquinone-hydroquinone couple (Em -305 mV and -520 mV respectively). Only AcFldB was competent to act as an electron donor to the Mo-containing nitrogenase of A. chroococcum. The N-terminal amino acid sequence (20 residues) of AcFldB was identical with that predicted from the nifF DNA sequence of A. vinelandii OP [Bennett, Jacobsen & Dean (1988) J. Biol. Chem. 263, 1364-1369], suggesting that AcFldB is the nifF gene product of A. chroococcum (MCD1155). Direct fast reversible electrochemistry of these flavodoxins has been achieved at a polished edge-plane graphite electrode using the aminoglycoside neomycin as a promoter. The heterogeneous rates of electron transfer between the graphite electrode and AcFldA and AcFldB were determined to be 1.2 x 10(-3) cm.s-1 and 2.0 x 10(-3) cm.s-1 respectively. The natures of two minor species of flavodoxin designated AcFldC and AcFldD, which were resolved by f.p.l.c., are also discussed.
Welfare/Efficiency Interactions in Selected West European Countries (1978)

This chapter presents brief analyses of the differing relationships between welfare and efficiency in six West European nations. The purposes are (a) to explain the main factors involved in the changes in this relationship in each country and (b) to ascertain whether negative-sum effects have already arisen or are likely to emerge in the coming years that contribute to neomercantilist trends. For these purposes, it is not necessary to give a comprehensive account of the progress, problems and policies of each national economy. Only those aspects will be covered that help to illuminate the nature and consequences of the welfare/efficiency relationship. However, as explained in Chapter 1, even this limited aim cannot be fully achieved due to the incompleteness of the available data.KeywordsWelfare BenefitInternational CompetitivenessUnit Labor CostSocial Security ContributionMarket SectorThese keywords were added by machine and not by the authors.

Cytokines in juvenile dermatomyositis pathophysiology: potential and challenge (2003)

The limited data suggest that a possible viral/microbial antigen may elicit an interferon-alpha/beta-induced response, and that antigenic epitopes may be shared. Increased synthesis of tumor necrosis factor-alpha, more common in juvenile dermatomyositis with the tumor necrosis factor-alpha-308A polymorphism, may augment this response and is associated with a wide range of pathologic consequences, as well as disease chronicity and calcifications. The muscle fibers themselves can regulate local inflammation by production of tumor necrosis factor-alpha, interleukin-15 and interleukin-1alpha, and transforming growth factor-beta.
CANDID: Classifying Assets in Networks by Determining Importance and Dependencies (2013)

This thesis introduces CANDID, a passive NetFlow-based network traffic analysis platform targeted at inferring relationships and dependencies among services running on hosts in enterprise networks. These networks present challenges of great scale, complexity, and nonstop dynamism, which hinder the ability for network administrators to maintain insight into the complex relationships that exist in these networks. Consequently, administrators do not always know how best to proceed if a network failure occurs. CANDID strives to empower administrators by illuminating these relationships, such that they will be prepared to remedy complex service failures. The solutions presented here take the first steps towards understanding these complex in-network relationships, with a special focus on inferring one class of dependencies and detecting load balanced services. The focal point of this thesis is two radically different, yet complementary, strategies for inferring the presence of load balancing for pairs of systems. A case study using real NetFlow data from the network located at Lawrence Berkeley National Lab is leveraged to validate the strategies presented here. Promising results indicate this problem space is rich with unanswered research questions and is worthy of further exploration.
Synucleins Are a Novel Class of Substrates for G Protein-coupled Receptor Kinases (2000)

G protein-coupled receptor kinases (GRKs) specifically recognize and phosphorylate the agonist-occupied form of numerous G protein-coupled receptors (GPCRs), ultimately resulting in desensitization of receptor signaling. Until recently, GPCRs were considered to be the only natural substrates for GRKs. However, the recent discovery that GRKs also phosphorylate tubulin raised the possibility that additional GRK substrates exist and that the cellular role of GRKs may be much broader than just GPCR regulation. Here we report that synucleins are a novel class of GRK substrates. Synucleins (alpha, beta, gamma, and synoretin) are 14-kDa proteins that are highly expressed in brain but also found in numerous other tissues. alpha-Synuclein has been linked to the development of Alzheimer's and Parkinson's diseases. We found that all synucleins are GRK substrates, with GRK2 preferentially phosphorylating the alpha and beta isoforms, whereas GRK5 prefers alpha-synuclein as a substrate. GRK-mediated phosphorylation of synuclein is activated by factors that stimulate receptor phosphorylation, such as lipids (all GRKs) and Gbetagamma subunits (GRK2/3), suggesting that GPCR activation may regulate synuclein phosphorylation. GRKs phosphorylate synucleins at a single serine residue within the C-terminal domain. Although the function of synucleins remains largely unknown, recent studies have demonstrated that these proteins can interact with phospholipids and are potent inhibitors of phospholipase D2 (PLD2) in vitro. PLD2 regulates the breakdown of phosphatidylcholine and has been implicated in vesicular trafficking. We found that GRK-mediated phosphorylation inhibits synuclein's interaction with both phospholipids and PLD2. These findings suggest that GPCRs may be able to indirectly stimulate PLD2 activity via their ability to regulate GRK-promoted phosphorylation of synuclein.
Bayesian method of inversion and a new strategy of inference on parameter estimation – An application on MT data (2003)

We describe a new interpretation technique in geophysical inversion that uses Box-Jenkins schema for model selection using Bayesian paradigm while model parameters are estimated using maximum a posteriori estimation procedure. We employ a regularized Gauss-Newton iterative optimization technique for selecting model parameters. Model discrimination and parameter appraisal have also been realized in the Bayesian framework. The model adequacy is tested using Bayesian information criterion (BIC) and logarithmic evidence criterion (LEC). The method is demonstrated with an application to field data.
n‐Type emitter epitaxy for crystalline silicon thin‐film solar cells (2007)

Abstract Crystalline silicon thin‐film (cSiTF) solar cells are an attractive alternative to bulk silicon solar cells. At Fraunhofer ISE we follow the concept of the epitaxial wafer equivalent (EpiWE), where 20 µm of silicon are deposited epitaxially by high temperature atmospheric pressure CVD (APCVD) on a cheap silicon substrate. The EpiWE can then be processed using standard industrial cell production. Furthermore, it is possible to simplify the solar cell process when depositing the emitter by epitaxy in‐situ after the growth of the base. The epitaxial emitter could be an alternative method of n‐type emitter processing with adjustable emitter profile and short deposition time. This paper presents results of cSiTF solar cells with epitaxial emitters and photolithographic contacts, which prove the good performance of the emitter and the applicability of the EpiWE to conventional solar cell processes. Included in the discussion is a description of the CVD deposition principle developed at Fraunhofer ISE and the applied clean room solar cell process. The emitter doping profiles and concentrations, as well as the structural quality, are discussed in detail using SIMS and SEM data. The phosphorus out‐diffusion during cooling is prevented by cooling the samples in a PH 3 /H 2 atmosphere. Moreover, a double‐layer emitter is formed having blue sensitive properties. The internal quantum efficiencies (IQEs) show that the emitter can be passivated as well as a ‘standard’ emitter formed by POCl 3 diffusion. Efficiencies up to 14·9 and 13·6% for large area cSiTF solar cells on highly doped Cz and mc, respectively, are presented. Copyright © 2007 John Wiley & Sons, Ltd.
Specific loss of protein kinase activities in senescent erythrocytes (1996)

Rabbit erythrocytes of progressively increasing age were isolated using an avidin-biotin affinity technique and the activity of protein kinases and other enzymes was analyzed in cytosols and membranes from the isolated cells. The activities of cytosolic protein kinase C (PKC), cAMP-dependent kinase (PKA), and casein kinase type I and II (CKI and II) were all found to undergo an age-dependent decrease of twofold to fourfold over the 8-week lifespan of the cells. Membrane-associated tyrosine kinase showed little or no decrease, but membrane-associated CKI showed a dramatic eightfold decrease over the 8-week period. By contrast, various cytosolic enzymes, including lactate dehydrogenase, phosphoglycerate kinase, pyruvate kinase, and acid phosphatase, showed no change in activity over the same time period. Density-separated human erythrocytes showed qualitatively similar decreases in cytosolic protein kinase activities in the densest fractions, which contain the oldest cells. Our results show that aging erythrocytes undergo progressive loss of protein kinases that may adversely affect various cellular processes. The age-dependent loss of kinase activity reported here is one of the most striking manifestations of erythrocyte senescence yet to be reported.
Influence of Conformation and Proton-Transfer Dynamics in the Dibenzyl σ-Complex on Regioselectivity in Gattermann−Koch Formylation via Intracomplex Reaction (1998)

The Gattermann−Koch formylations of diphenyl, diphenylmethane, dibenzyl, and 1,3-diphenylpropane were studied in HF−SbF5, −TaF5, −BF3, −NbF5, and CF3SO3H−SbF5. While usual high para regioselectivity was obtained for diphenyl, diphenylmethane, and 1,3-diphenylpropane, unprecedented ortho regioselectivity was observed for dibenzyl which increased with decreasing the SbF5/dibenzyl molar ratio and with strength of Lewis acids used in HF. A sandwich-like complex for monoprotonated dibenzyl resulting in ortho regioselectivity via the intracomplex reaction was suggested; therefore, the conformations of protonated diphenylmethane, dibenzyl, and 1,3-diphenylpropane and their proton-transfer dynamics were probed by semiempirical calculation (PM3). The calculation predicted that ortho monoprotonation was slightly preferable for dibenzyl, and remarkable preference of dibenzyl over other aromatic compounds was observed in ortho−ortho intramolecular inter-ring proton transfer via a fan-shaped complex rather than a sandwich-like complex. The experimental and theoretical data for dibenzyl are compatible with the intracomplex reaction, whereby CO is protonated by the ortho σ-complex undergoing rapid inter-ring proton transfer to generate formyl cation in the vicinity of the ortho position leading to ortho regioselectivity.
An integrated restoration system for SDH-based ATM transport networks (2002)

This paper describes an integrated restoration strategy suitable for protecting services which are supported by an SDH-based ATM transport network. Restoration protocols which were developed independently to operate within respective SDH and ATM path layers, are coordinated in a unified software framework. The method of service protection assumes that non-ATM services transported by SDH paths are restored at the SDH layer, whilst SDH paths bearing ATM traffic remain unprotected at the SDH layer, with ATM service protection being supplied at the virtual path (VP) layer. The inter-working required to provide a seamless restoration system is explained, and computer simulations are employed to validate the operation of the integrated strategy in the presence of physical layer faults.
Strategic Planning of Integrated Multirefinery Networks: A Robust Optimization Approach Based on the Degree of Conservatism (2010)

This paper considers the problem of strategic planning under uncertainty for optimal integration and coordination of a multirefinery network. The deterministic model proposed by Al-Qahtani and Elkamel [Comput. Chem. Eng. 2008, 32, 2189−202] was extended to account for uncertainties in raw material costs and final product prices, as well as product demand. The robust optimization methodology of Bertsimas and Sim [Op. Res. 2004, 52, 35−53] was applied, which deals with uncertainty in a tractable manner and does not add complexity to the deterministic problem. An industrial-scale study illustrated the benefits of the integrated planning and demonstrated that the modeling of uncertainty in process parameters provides a more practical perspective of the refining industry. In addition, probability bounds of constraint violation were calculated to help decision makers select appropriate parameters to control solution robustness and evaluate trade-offs between conservatism and total profit.
ACTR-33. A PHASE I STUDY OF CONVECTION-ENHANCED DELIVERY OF LIPOSOMAL-IRINOTECAN USING REAL-TIME IMAGING WITH GADOLINIUM IN PATIENTS WITH RECURRENT HIGH GRADE GLIOMA (2016)

Local delivery into the central nervous system circumvents the challenges associated with the blood-brain barrier and minimizes systemic toxicity while achieving higher concentrations of therapeutics. Convection enhanced delivery (CED) utilizes fluid convection to distribute macromolecules into the interstitial spaces of brain parenchyma. CED a high-concentration version of liposomal irinotecan (nal-IRI-HC) has been optimized in animal models and showed promising anti-tumor activity. A major recent advance in the application of CED is the development of real time CED (RCD), which utilizes MRI to visualize the CED process with the aid of co-convected contrast agents and thus monitor infusions and ensure precise delivery. A phase I study is ongoing evaluating CED of nal-IRI-HC with real-time MRI for patients with recurrent high grade glioma (HGG). This 3+3 dose escalation trial employs dose levels of 20 mg, 40 mg, 60 mg, and 80 mg of nal-IRI-HC, given via up to 3 catheters surgically placed in an intra-tumoral location. Maximum total volume infused will be 1.0 ml for the two lowest dose groups, 1.5 ml for the third dose group, and 2.0 ml for the highest dose group. To date 7 patients have been enrolled and treated. Median progression free survival was 2.9 months. All radiographic progression was found to be outside the infusion area. One grade 3 adverse event was encountered. The median total volume of distribution (Vd) to volume infused (Vi) ratio was 1.6 - 2.0 for each infusion based on correlations between pre-infusion modeling of drug distribution and post-infusion imaging. Image-guided CED allows for real-time placement and adjustment of cannula and for real time visualization of therapeutics into the brains of patients with recurrent HGG. In this early phase trial, real time CED of nal-IRI-HC appears well tolerated and suggests larger volume infusions warrants clinical evaluation.
Interaction of Asp. melleus Semi-alkaline protease with benzeneboronic acid. (1977)

Benzeneboronic acid (BBA), a possible transition-state analog for serine proteases, was found to inhibit Asp. melleus semi-alkaline protease [EC 3.4.21.15]. The pH dependence of inhibitor constants was studied by the pH-stat method using N-acetyl-L-tyrosine ethyl ester as a substrate at 25 degrees C. From the pH dependence of the association constant (reciprocal inhibitor constant), a pK value of 6.6, which may be attributable to the catalytic histidine residue of the enzyme, was estimated. The BBA-enzyme interaction was studied kinetically by the temperature-jump method. Apparent association and dissociation rate constants were determined at pH 6.5.
10.1016/j.admecli.2006.06.014 (2000)

Acne vulgaris is a nearly universal phenomenon among adolescents in the western world and continues to remain problematic for a significant proportion of adults. During adolescence, emotional and physical changes must be successfully integrated into the emerging sense of self, and skin disorders such as acne, which alter that self-image, may engender distressing feelings of embarrassment, shame, and disgust. While most patients eventually achieve spontaneous remission, approximately one quarter of teenagers will show evidence of permanent acne scarring by 18 years of age. This article reviews current information regarding the pathophysiology, clinical manifestations, differential diagnosis, and therapy of the adolescent patient who has acne, and emphasizes recent advances in acne management.

Ausblick in das Weltall (1968)

ZusammenfassungDer Ausblick in das Weltall war für den Menschen des Mittelalters ein Blick in eine Wirklichkeit hinter den Sternen. Das Himmelsgewölbe, an dem die Fixsterne gleich silbernen Nägeln befestigt waren und von dem sie einst am Jüngsten Tag herabfallen würden, umgab wie ein schützender Mantel die scheibenförmige Erde mit ihren Bergen, Städten und Meeren. So stellt es in einer selbst für jene Zeit naiven Vereinfachung ein Einblattdruck um 1530 (Abb. 1) dar. Dem staunenden Blick des Pilgers, dem es auf seiner Wanderung gelingt, die kristallene Sphäre zu durchstoßen, öffnet sich eine unbekannte lichte Welt, der Wohnsitz Gottes und der seligen Geister.
Monoclonal Antibody-Based Detection System for Salmonella enteritidis (1993)

Two monoclonal antibodies that react with Salmonella enteritidis in chicken tissue, eggs, and environmental samples were used to develop a rapid enzyme-linked immunosorbent assay (ELISA) screen and agglutination assay for the specific detection of S. enteritidis. S. enteritidis was detected in 100% of egg samples and 99.8% of various field and research samples by both ELISA and traditional microbiological isolation and identification techniques. Results of titer experiments indicate that as few as 10(4) organisms can be detected by ELISA.
