The coolant and cable core temperatures were calculated by numerically solving the heat equation using the finite difference method. In the calculation, we assume that the heat transfer coefficient between the flowing subcooled liquid nitrogen and the cable core surface is described by the Dittus-Boelter correlation. The calculation results reveal that the coolant temperature increases even after the fault has been removed and that it continues increasing until fresh coolant arrives from the inlet. The calculated temperature profile of the coolant agrees well with measured data obtained by conducting over-current tests on a model HTS cable. Using our computational code, we also evaluated the maximum HTS cable lengths that ensure that the coolant remains in the liquid phase for certain fault currents for an HTS model cable.
Sources of Acquisition Cultural Risk (1994)

Previous work on acquisitions, and especially on post-acquisition integration, has put more emphasis on strategic fit than on organisational and cultural fit of acquiring and target firms. Academic writings on corporate acquisitions approach the need to reassure employees in this stressful situation and to enlist their commitment to the new organisation. Yet cultural compatibility is frequently noted to be critical to the success of acquisitions in practice. Superior practice is exemplified by ARA Services, a company that — according to its CEO, William S. Fishman — has acquired over 300 companies and 'maintained over 80 per cent of the acquired management through these years'. ARA's criteria for evaluating acquisition candidates is a balance of traditional business criteria and people criteria. We select the candidate firms very carefully on the basis of their record of growth, record of performance, record of earnings, their reputations for integrity and good business practice, and very importantly, the quality of their management. We determine whether the personalities of the acquired company and ours will match. All marriages were not made in heaven and all acquisitions are not made in heaven. We've walked away from many acquisitions because we felt that the management of the company was not likely to be a good partner for us, nor we for them.

Size and ligand effects on the electrochemical and spectroelectrochemical responses of CdSe nanocrystals (2005)

The electrochemical properties of CdSe quantum dots with electrochemically inactive surface ligands (TOPO) have been investigated in comparison with the analogous nanocrystals containing electrochemically active oligoaniline ligands. The TOPO-capped nanocrystals have been studied in a wide size range (from 3 to 6.5 nm) with the goal to amplify the influence of the quantum confinement effect on the electrochemical response. The determined HOMO and LUMO levels have been found in good agreement with the ones obtained from photoluminescence studies and those predicted theoretically. Ligand exchange with aniline tetramer significantly influences the voltammetric peaks associated with the HOMO oxidation and the LUMO reduction of the quantum dots, which are shifted to higher and lower potentials, respectively. These shifts are interpreted in terms of the positive ligand charging which precedes the oxidation of the nanocrystals and the insulating nature of the ligand in the case of the nanocrystal reduction. The ligand-nanocrystal interactions have also been studied by UV-Vis-NIR and Raman spectroelectrochemistry in comparison with a specially prepared model compound which, apart from the anchoring function is identical to the grafted oligoaniline ligand. Both spectroelectrochemical techniques clearly indicate the same nature of the oxidation/reduction pathway for both the model compound and the grafted ligand. The influence of the grafting is manifested by a shift in the onset of the ligand oxidation as compared to the case of the "free" model compound. Since both components (ligands and nanocrystals) mutually influence their electrochemical and spectroelectrochemical properties, the newly developed system can be considered as a true molecular hybrid. Such hybrids are of interest because the potential zone of the ligand electroactivity is well separated from that of the nanocrystals and, as a result, the organic part can be electrochemically switched between the semiconducting and the conducting states with no change in the oxidation state of the nanocrystal. The newly developed system offers therefore the possibility of an electrical addressing of individual nanocrystals via the conducting ligands.
Spatially Resolved Resistivity Measurements in Semiconductor Wafers using Microwave Techniques (1990)

In this paper we present a 35 Ghz microwave reflection system which we have used for measuring the resistivity of semiconductor wafers. By using a tapered parallel plate antenna for directing the microwave radiation on to the wafer there is no need for placing the sample inside a waveguide. The system can measure resistivity in the range of 0.5 Ω-cm to 50 μ-cm with a spatial resolution of 0.040" × 0.040" which is similar to what can be achieved using standard four point probes.

Active Input–Voltage and Load–Current Sharing in Input-Series and Output-Parallel Connected Modular DC–DC Converters Using Dynamic Input-Voltage Reference Scheme (2004)

This paper explores a new configuration for modular DC/DC converters, namely, series connection at the input, and parallel connection at the output, such that the converters share the input voltage and load current equally. This is an important step toward realizing a truly modular power system architecture, where low-power, low-voltage, building block modules can be connected in any series/parallel combination at input or at output, to realize any given system specifications. A three-loop control scheme, consisting of a common output voltage loop, individual inner current loops, and individual input voltage loops, is proposed to achieve input voltage and load current sharing. The output voltage loop provides the basic reference for inner current loops, which is modified by the respective input voltage loops. The average of converter input voltages, which is dynamically varying, is chosen as the reference for input voltage loops. This choice of reference eliminates interaction among different control loops. The input-series and output-parallel (ISOP) configuration is analyzed using the incremental negative resistance model of DC/DC converters. Based on the analysis, design methods for input voltage controller are developed. Analysis and proposed design methods are verified through simulation, and experimentally, on an ISOP system consisting of two forward converters.
[A potential mechanism for impaired wound healing--cutaneous environmental disorders in diabetes mellitus]. (2008)

Impaired wound healing in diabetes is a significant clinical problem which is thought to be associated with neuropathy and angiopathy previously . The present study indicates that accumulation of glucose and glycometabolic products in skin tissue, as the result of glycometabolic disorders, which contributes to cutaneous environmental alterations in diabetes mellitus, and subsequently induces the abnormal cell behaviors, cytokine alteration and matrix modification. Thus, diabetic neuropathy and angiopathy might be regarded as the pathological outcome of cutaneous environmental alterations. In conclusion, glycometabolism disorders could be described as one of the initial events for the alteration involving in the underlying cutaneous disorder which impair healing process. The related research focuses on the initial event of controlling disorders in wound healing and therefore contribute to providing the strategy of treatment as based on these approaches.
Influence of ferromagnetic bridges in dq-equivalent-circuit modeling of interior permanent-magnet machines (2014)

To reach energy efficiency goals the demand to high efficient motors, among which Permanent Magnet Motors, is increasing. In order to analyze and to predict the performance, equations based on equivalent circuits are generated. Lumped parameters have to be estimated and for simplicity often coarse assumptions are made, affecting the accuracy of the model. In this paper flux-linkage and inductance variations in (LineStart) Interior Permanent-Magnet Synchronous Machines are discussed. Attention is given to the influence of the behavior of the ferromagnetic material caused by load angle and current variations and more specific to the geometric design parameters, in particular to the magnetic conductance of the bridges. Finite Element Method is used for parameter estimations and detailed magnetic field research.

Does needle rotation improve lesion targeting? (2011)

The new needle driver provides a unique kinematic architecture that enables insertion with a compact mechanism. Perhaps the most interesting conclusion of the study is that lesions of soft tissue organs may not be perfectly targeted with a needle without using special techniques, either manually or with a robotic device. The results of this study show that needle rotation may be an effective method of reducing targeting errors.
Synthesis and Characterization of Tetrahydropyran-Based Bacterial Topoisomerase Inhibitors with Antibacterial Activity against Gram-Negative Bacteria (2017)

There is an urgent unmet medical need for novel antibiotics that are effective against a broad range of bacterial species, especially multidrug resistant ones. Tetrahydropyran-based inhibitors of bacterial type II topoisomerases (DNA gyrase and topoisomerase IV) display potent activity against Gram-positive pathogens and no target-mediated cross-resistance with fluoroquinolones. We report our research efforts aimed at expanding the antibacterial spectrum of this class of molecules toward difficult-to-treat Gram-negative pathogens. Physicochemical properties (polarity and basicity) were considered to guide the design process. Dibasic tetrahydropyran-based compounds such as 6 and 21 are potent inhibitors of both DNA gyrase and topoisomerase IV, displaying antibacterial activities against Gram-positive and Gram-negative pathogens (Staphylococcus aureus, Enterobacteriaceae, Pseudomonas aeruginosa, and Acinetobacter baumannii). Compounds 6 and 21 are efficacious in clinically relevant murine infection models.
Improved Constraints on Sedimentary Environments of Palygorskite Deposits of the Hawthorne Formation, Southern Georgia, from a Detailed Study of a Core (2004)

Abstract The sedimentology and mineralogy of a 2.5 m core from a palygorskite deposit of the Miocene Hawthorne Formation, southern Georgia is described. The lithology involves laminated clay-rich sediment composed of ∼90% clay and 10% sand, with six clay-pebble layers present. Sand to pebble-size clasts of phosphate material are common throughout the core. The sand laminations are probably flood-related and the clay-pebble layers are storm deposits, with the pebbles being derived locally from subaerial environments. Phosphate clasts are reworked bone material. The sands are quartz-rich and are subarkosic in composition with average quartz counts of 86.50% and average total feldspar counts of 11.50%. Heavy minerals observed include orthopyroxene, clinopyroxene, amphibole, zircon, rutile, garnet, tourmaline, kyanite, muscovite, biotite, spinels and opaques. Palygorskite fibers dominate the clay-size fraction of the samples and comprise ∼80–90% of sample material with smectite comprising the remainder. Hydroxylapatite comprises ∼3% of sediment volume and occurs as individual euhedral hexagonal crystals and as clusters of crystals. Investigation of this core suggests that the palygorskite deposit represents a dynamic system with regular flooding and storm deposition being common. Mineral composition of sands may be useful for stratigraphic correlation of palygorskite deposits in the Apalachicola Embayment. This study supports the general environmental interpretations of previous workers for the palygorskite deposits of southern Georgia, but provides greater detail.
Über Fluorphosphin‐Komplexe des Nickels (1961)

Abstract Aus den entsprechenden Chlorverbindungen konnten durch Umsetzung mit Kaliumfluorsulfinat Nickel‐tetrakis‐trifluorphosphin, Ni(PF 3 ) 4 , Nickel‐tetrakis‐methyldifluorphosphin Ni(PF 2 CH 3 ) 4 , als Flüssigkeiten und das feste Nickel‐tetrakis‐phenyldifluorphosphin, Ni(PF 2 C 6 H 5 ) 4 , erhalten werden. Es handelt sich hierbei – abgesehen von der Methylverbindung – um recht beständige Stoffe, die weiteren Umsetzungen zugänglich sind. So entsteht aus Ni(PF 3 ) 4 und flüssigem Ammoniak offensichtlich zunächst Nickel‐tetrakis‐triamidophosphin, [Ni(P(NH 2 ) 3 ] 4 , das rasch zu Nickel‐tetrakis‐nitridophosphin, [Ni(PN) 4 ] n , polykondensiert. Die IR‐Spektren der Komplexverbindungen sind innerhalb des NaCl‐ und CsBr‐Bereiches nahezu identisch mit den Spektren der freien Phos‐phin‐Liganden. – Erfahrungen hinsichtlich des Nickel‐tetrakis‐trichlorphos‐phins werden mitgeteilt.
Iterative implementations of linear receivers for spatial diversity channels (2002)

We investigate iterative implementations of linear receivers for spatial diversity channels This work has been motivated by previous results concerning iterative implementations of linear multiuser receivers, under the assumption of long random sequences. We explore implementation issues for such iterative methods for finite system dimensions. We consider the Chebyshev iteration using estimates of the extreme eigenvalues based on the Gersgorin circle theorem. This method achieves the same bit error rate performance as direct implementation yet requiring very few iterations. This reduces the computational cost of the receiver.
On the Average Complexity of Reed–Solomon List Decoders (2013)

The number of monomials required to interpolate a received word in an algebraic list decoder for Reed–Solomon codes depends on the instantaneous channel error, and not only on the decoder design parameters. The implications of this fact are that the decoder should be able to exhibit lower decoding complexity for low-weight errors and, consequently, enjoy a better average-case decoding complexity and a higher decoding throughput. On the analytical side, this paper studies the dependence of interpolation costs on instantaneous errors, in both hard- and soft-decision decoders. On the algorithmic side, it provides an efficient interpolation algorithm, based on the state-of-the-art interpolation algorithm, that enjoys reduced running times for reduced interpolation costs.
Doing experimental syntax: Bridging the gap between syntactic questions and well-designed questionnaires (2012)

People with upper body or visceral obesity have a much higher risk of morbidity and mortality from obesity-related metabolic disorders than those with lower body obesity. In an attempt to develop therapeutic strategies targeting visceral obesity, depot- specific differences in the expression of genes in omental and subcutaneous adipose tissues were investigated by DNA array technology, and their roles in adipocyte differentiation were further examined. We found that levels of metallothionein-II (MT-II) mRNA and protein expression were higher in omental than in subcutaneous adipose tissues. The study demonstrates that MT-II may play an important role in adipocyte differentiation of 3T3L1 preadipocytes, and that N-acetylcysteine (NAC) inhibits the adipocyte differentiation of 3T3L1 cells by repressing MT-II in a time- and dose-dependent manner. Furthermore, the intraperitoneal administration of NAC to rats and mice resulted in a reduction of body weights, and a marked reduction in visceral fat tissues. These results suggest that MT-II plays important roles in adipogenesis, and that NAC may be useful as an anti-obesity drug or supplement.
Deep Residual Learning Meets OFDM Channel Estimation (2019)

In this letter we apply deep learning tools to conduct channel estimation for an orthogonal frequency division multiplexing (OFDM) system based on downlink pilots. To be specific, a residual learning based deep neural network specifically designed for channel estimation is introduced. Due to the compact network size as well as the underlying network architecture, the computation cost can be greatly reduced. Furthermore, this residual network architecture is compatible with any downlink pilot patterns making it compatible for modern wireless systems. The estimation error of the introduced residual learning approach is evaluated under 3rd Generation Partnership Project (3GPP) channel models. It outperforms other deep learning based estimation method with comparable to minimum mean square error (MMSE) estimation performance.
Use of an Adjustable Impact Bead in the Analysis of Solutions in Organic Solvents by Flame Atomic Absorption (1992)

Throughput of organic solvent aerosol to the flame of an atomic absorption spectrometer may be controlled by varying the position of the impact bead relative to the nebulizer, instead of varying the solution uptake rate of the nebulizer. The usefulness of this simple technique has been demonstrated for a range of elements in three organic solvents (4-methylpentan-2-one, xylene, and a high-boiling-point iso-paraffin solvent), with air/C 2 H 2 and N 2 O/C 2 H 2 flames. It is shown that the adjustment of the impact bead alone allows the determination of high concentrations of copper and iron in lubricating oils without undue dilution of the sample and can result in significant improvements in the speed of analysis.
In vivo release and retinal safety of intravitreal implants of thalidomide in rabbit eyes and antiangiogenic effect on the chorioallantoic membrane (2013)

The intravitreal implants delivered safe doses of thalidomide that were also effective to induce vessels regression in CAMs.
User assisted text classification and knowledge management (2003)

While there are many aspects to managing corporate knowledge, one key issue is how to organize corporate documents into categories of interest. In this paper, we focus on using user assisted text classification in conjunction with a web portal, multiple document management systems and an ontology, to provide a powerful solution for organizing information about a company's technology. We propose a system that interacts with an author using an automatic text classifier to suggest controlled keywords to be used as metadata. The proposed approach does not require professional librarians or that the end users have extensive training. The use of a controlled vocabulary allows for a more consistent description of corporate documents, and promotes easier access by people across the company. It is easier to find similar documents which use different nomenclature. Finally, the interactive nature of the system results in a more correct and precise description of each document than a fully automatic system would.
Aqueous diffusion through partition membranes (1973)

Abstract Diffusion data obtained from Leonard‐Bluemle cell was interpreted in terms of the extent of interaction between solute and membrane matrix. A new equation was developed to provide linear fit curve for the half‐time data measurements. To develop an understanding of these partition type membranes on the molecular basis, the absolute reaction rate theory has been explored.

Fluid Petri Nets for the Performance Evaluation of MapReduce and Spark Applications (2017)

Big Data applications allow to successfully analyze large amounts of data not necessarily structured, though at the same time they present new challenges. For example, predicting the performance of frameworks such as Hadoop and Spark can be a costly task, hence the necessity to provide models that can be a valuable support for designers and developers. Big Data systems are becoming a central force in society and the use of models can also enable the development of intelligent systems providing Quality of Service (QoS) guarantees to their users through runtime system reconfiguration. This paper provides a new contribution in studying a novel modeling approach based on fluid Petri nets to predict MapReduce and Spark applications execution time which is suitable for runtime performance prediction. Models have been validated by an extensive experimental campaign performed at CINECA, the Italian supercomputing center, and on the Microsoft Azure HDInsight data platform. Results have shown that the achieved accuracy is around 9.5% for Map Reduce and about 10% for Spark of the actual measurements on average.
Verarbeitung von propriozeptiver Information beim idiopathischen Parkinson-Syndrom und der Einfluss von Levodopa (2008)

Einleitung: Muskelvibration (MV) beeinflusst die Wahrnehmung von Bewegung und Lagesinn besonders in Abwesenheit visueller Kontrolle. Beim idiopathischen Parkinson-Syndrom (IPS) hat MV einen geringeren Einfluss auf Kinästhesie als bei Gesunden, der aber durch dopaminerge Medikation wieder vergrößert werden kann. Man misst diesen Besonderheiten eine Bedeutung bei der Entstehung von Hypometrie und Bradykinese bei. Die genauen Mechanismen des verminderten Einflusses von MV auf Kinästhesie beim IPS sind unklar.
