EM simulation of planar bus bars in multi-level power converters (2012)

This paper presents recent progress in the acceleration of PEEC based electromagnetic simulations and its impact on the design of complex bus bar structures as used in multilevel power converters. The approach presented consists of different dedicated acceleration methods for the different design tasks. The first acceleration technique applied is the so called reluctance matrix method for full 3D field results, reducing memory consumption by orders of magnitude and computing time by a factor 3 to 5. The second acceleration method applied is based on model order reduction techniques for port-to-port impedance extraction, reducing the computation time by about one order of magnitude and allowing wideband macro modeling for system level simulations. The paper focuses on the application of these methods showing the impact on practical bus bar design tasks.
COBRA: center-oriented broadcast routing algorithms for wireless ad hoc networks (2004)

We provide the initial framework for the study of center-oriented broadcast routing problems using omnidirectional antennas. From the intuition that the best place to take advantage of the wireless broadcast advantage is at the center of a network deploy region, we concretize this idea into a currently best performing power-efficient broadcast routing algorithm for wireless ad hoc networks. We support this statement with extensive simulation studies.
In-Hospital and One-Year Economic Outcomes After Coronary Stenting or Balloon Angioplasty (1995)

Elective coronary stenting, as performed in the randomized STRESS trial, increased total 1-year medical care costs by approximately $800 per patient compared with conventional angioplasty. Future studies will be necessary to determine whether ongoing refinements in stent design, implantation techniques, and anticoagulation regimens can narrow this cost difference further by reducing stent-related vascular complications or length of stay.
Activation of rat intestinal mucosal mast cells by fat absorption (2012)

Previous studies have linked certain types of gut mucosal immune cells with fat intake. We determined whether fat absorption activates intestinal mucosal mast cells (MMC), a key component of the gut mucosal immune system. Conscious intestinal lymph fistula rats were used. The mesenteric lymph ducts were cannulated, and the intraduodenal (i.d.) tubes were installed for the infusion of Liposyn II 20% (an intralipid emulsion). Lymphatic concentrations of histamine, rat MMC protease II (RMCPII), a specific marker of rat intestinal MMC degranulation, and prostaglandin D(2) (PGD(2)) were measured by ELISA. Intestinal MMC degranulation was visualized by immunofluorescent microscopy of jejunum sections taken at 1 h after Liposyn II gavage. Intraduodenal bolus infusion of Liposyn II 20% (4.4 kcal/3 ml) induced approximately a onefold increase in lymphatic histamine and PGD(2), ∼20-fold increase in lymphatic RMCPII, but only onefold increase in peripheral serum RMCPII concentrations. Release of RMCPII into lymph increased dose dependently with the amount of lipid fed. In addition, i.d. infusion of long-chain triacylglycerol trilinolein (C18:2 n-6, the major composite in Liposyn II) significantly increased the lymphatic RMCPII concentration, whereas medium-chain triacylglycerol tricaprylin (C8:0) did not alter lymph RMCPII secretion. Immunohistochemistry image revealed the degranulation of MMC into lamina propria after lipid feeding. These novel findings indicate that intestinal MMC are activated and degranulate to release MMC mediators to the circulation during fat absorption. This action of fatty acid is dose and chain length dependent.
Decoupling of time scales of motion in polybutadiene close to the glass transition (1992)

Studying the dynamic structure factor of polybutadiene in the first valley of S(Q) we observed a decoupling of microscopic and macroscopic time scales about 40\ifmmode^\circ\else\textdegree\fi{} above ${\mathit{T}}_{\mathit{g}}$. At higher temperatures the time scale set by the viscosity scales with the microscopic scale, while at lower T strong decoupling effects occur. We present evidence that the decoupled low-temperature relaxation is distinctly different from the high-frequency ``\ensuremath{\beta} process.'' The decoupling temperature coincides with the critical temperature of the mode coupling theory.

Optimizing driver acceptance and objective benefit using Predictive Collision Warning as an example (2006)

The end customer acceptance of safety systems depends only very indirectly on the actual advantages of the system: accidents occur very rarely, and the actual benefits in such situations can only be judged subjectively with difficulty. The usefulness of the collision warning system discussed here can be objectively defined very precisely. An warning occurs if the system gives a warning in a situation in which the driver could have avoided a collision without support from the system. The end customer experiences the system in normal circumstances through these erroneous warnings. The acceptance of the system is determined by the situations in which warnings occur and the chosen actuators through which the warning is given. Warning systems can therefore be categorised as those which attempt to derive their acceptability from the subjective expectations of the driver, and those which attempt to increase acceptability by keeping the number of erroneous warnings to a minimum. In this paper, a method is presented in which a system can be assessed and optimally parameterised according to the desired implementation. The explicit aim is to obtain an optimum balance between acceptability and objective system usability, in order to find the correct implementation for the end customer and vehicle. Language: de.
QUICK AND EASY FABRICATION OF MICROFLUIDIC CHANNELS WITH WATER- SOLUBLE MOLDS (2008)

We describe an inexpensive technique for rapidly generating microfluidic devices. We use a cutting-plotter machine to cut commercially available watersoluble starch sheets into channels to build the master mold for the devices. We degas the poly(dimethylsiloxane) (PDMS) with a portable vacuum sealer and cure it in a microwave. Using this method, we can fabricate T-junction microfluidic devices, stamps for micro-contact printing and 3D microfluidic channels. The total processing time is less than 90 min. This method can be used by scientists without access to microfabrication facilities and can be applied in science education.
Development of NS Tension System for Space Frame (2005)

string structures using cable or high-strength rods are now becoming very popular for spatial structures such as sports gymnasium, convention center, entrance hall, and so on. These structures are one of the most rational structural systems, which use steel members under pure tension forces, without buckling. They are lightweight, high-strength/stiffness, and realizing elegant appearances. How- ever, because of using special types of steel materials, individual approval is re- quired for the practical construction, which obstructs the designers from adoption to building design. Since1990, Nippon Steel / Building Construction Div. has been endeavoring on the systematization of Tension Roof System and Tension Graz- ing System, developing the market by authorizing the general approvals for build- ing use. In this paper, parts of general technical information of this system are reported.
Solvent isotope effects on chemical shifts of ions in aqueous solutions (1968)

A. Loewenstein, M. Shporer, P. C. Lauterbur and J. E. Ramirez, Chem. Commun. (London), 1968, 214 DOI: 10.1039/C19680000214
The Case for Embedded Networks on Chip on Field-Programmable Gate Arrays (2014)

FPGAs are becoming more powerful computing devices as a result of increased logic capacity, inclusion of embedded processors and I/O controllers, and the rise of high-level programming-language-to-hardware compilers. However, accelerating computing applications on FPGAs is still challenging, partly due to the need for low-level hardware design of a system-level interconnect to integrate the application components. The authors propose augmenting the FPGA architecture with an embedded NoC to implement the system-level communication infrastructure and mitigate the hardware design challenges faced by current bus-based interconnects. With a flexible interface between the NoC and the FPGA fabric, an embedded NoC maintains the configurability of the FPGA, and simplifies distribution of I/O data throughout the chip. Embedded NoCs are always more energy-efficient compared with custom buses configured into the fabric by commercial system integration tools, and they save area for most systems as well.
Multisource PD identification based on phase synchronous and asynchronous data (2011)

Partial Discharge (PD) measurements in cables and their accessories play a fundamental role in Condition Based Monitoring (CBM) of High Voltage (HV) equipment. CBM monitoring has been enforced by utilities in the transmission and distribution (T&D) environment as part of a predictive maintenance program that aims to result in less unscheduled downtime and lower maintenance cost. Identifying the source of a PD rather than merely assessing its magnitude provides additional information that could enable more educated decisions concerning the integrity of the insulation to be made. In on-line scenarios the presence of multiple PD sources that are simultaneously active as well as the presence of interference, complicates the identification process. In this paper, the Density-Based Spatial Clustering of Applications with Noise (DBSCAN) algorithm has been employed to identify PDs of different sources. Phase synchronous measurements were acquired in the laboratory and pre-processed through a peak detection algorithm to extract the single pulses (phase asynchronous). To extract a feature the Wavelet Packet Transform (WPT) and Higher Order Statistics (HOS) were employed according to previous work by the authors. The feature was then analyzed by the Principal Component Analysis (PCA) for dimensionality reduction and study of different PD sources has been shown to form separate clusters. Application of this method on on-line data acquired from the network of the Electricity Authority of Cyprus (EAC) has demonstrated its potential use in PD identification and interference rejection.

Regioselective Synthesis of Indoles via Reductive Annulation of Nitrosoaromatics with Alkynes (2002)

[reaction: see text] Indoles are produced regioselectively and in moderate yields by two new processes: (a) from the [CpRu(CO)2]2-catalyzed reaction of nitrosoaromatics (ArNO) with alkynes under carbon monoxide and (b) in a two-step sequence involving the (uncatalyzed) reaction of ArNO with alkynes, followed by reduction of the intermediate adduct.

Scattering of Magnetic Mirror Trapped Fast Electrons by a Shear Alfvén Wave (2012)

Laboratory observations of enhanced loss of fast electrons trapped in a magnetic mirror geometry irradiated by shear Alfvén waves (SAW) are reported. A population of runaway electrons generated by second harmonic electron-cyclotron-resonance heating, as evidenced by the production of hard x rays with energy up to 3 MeV, is subjected to SAW launched with a rotating magnetic field antenna. It is observed that the SAW dramatically affect the trapped fast electrons and scatter them out of the magnetic mirror despite any obvious resonance. The results could have implications on the techniques of artificial reduction of energetic electrons in the inner radiation belt.

Developing the tourism aspects of a cultural route (2004)

A cultural route links destinations that contain illustrations of a common theme, for example religion. It has been reported that the number of cultural routes are increasing. However, to date there is no evidence in the literature of any studies developing a framework which outlines the information visitors may require when following a cultural route. This paper describes a framework which is designed to be used by those responsible for planning and implementing cultural routes. The framework also serves as the structure of a web portal that is intended to act as an example of good practice for other cultural route portals to follow.
Aspects of Thioanhydhide Chemistry (1989)

Abstract Cyclic anhydrides constitute one of the most thoroughly studied classes of organic compounds. In contrast, very little is as yet known concerning the thiocarbonyl analogs of cyclic anhydrides. In this lecture, the present status of thionoanhydride chemistry will be reviewed, with emphasis on studies from our laboratory.
Evidence for an ester linkage between lignin and glucuronic acid in lignin-carbohydrate complexes by DDQ-oxidation. (1988)

Ester linkages between the carboxyl group in glucuronic acid and lignin in lignified plant cell walls have often been demonstrated by alkaline degradation or sodium borohydride reduction of acidic lignin-carbohydrate complexes (LCC).1~3) However, each of these methods has one serious disadvantage that the binding unit toward the glucuronic acid residue is indeterminate. In this article, we report a novel technique to obtain direct evidence for ester linkages between glucuronic acid and lignin by adopting selective cleavage of methoxybenzyl glucuronate with 2,3dichloro-5,6-dicyano-l ,4-benzoquinone (DDQ).
Influence of Stress on Peel Strength of Acid Copolymers to Foil (2002)

As an acid copolymer is converted in the extrusion coating process, it undergoes considerable stress and orientation. This stress arises from shear forces in the extruder and die, from extensional forces as the melt curtain is drawn down and from shrinkage forces during crystallization. It is hypothesized that these stresses may influence peel strength by impacting tensile properties and residual stress at the foil-polymer interface. Relationships are developed between stress and common processing parameters such as air gap, die gap, melt temperature and line speed. An experiment is described where processing parameters were changed in a systematic way to alter the stress imposed on the polymer. Data is presented which strongly supports the hypothesis, and provides an understanding as to the role and impact of various processing parameters.
Population Data for Seven Y-Chromosome STR Loci from Three Different Population Groups Residing in Connecticut (2003)

Abstract The samples for database studies were obtained from unrelated males from the indicated population groups residing in the state of Connecticut and were anonymized before analysis. The DNA from blood samples was extracted using the QIAamp® DNA blood MiniKit (Qiagen, Valencia, CA) following the recommended procedures. The quantity of human DNA was determined by slot blot hybridization using the QuantiBlot kit (Applied Biosystems, Foster City, CA) and following the manufacturer's recommended protocols. The Y-PLEX™6 system (ReliaGene Technologies, Inc., New Orleans, LA) was used for the amplification of the Y short tandem repeat (STR) loci. PCR amplification and the analysis of amplified product were performed as recommended by the manufacturer and as described in Sinha et al. (1).
Effects of wall moisture profiles on matched illumination waveforms &#x2014; Simulation and measurement (2014)

The effects of wall moisture on the characteristics of matched illumination waveforms for use in through the wall radar imaging (TWRI) are examined via simulation. Various wall moisture profiles are considered for solid adobe-like walls including a uniform moisture profile, moisture concentrated in the interior region of the wall, and moisture concentrated at the exterior surface. Specific characteristics of the typical optimum waveform are noted for each of the moisture profiles considered. Techniques for experimentally validating the performance of the matched illumination waveforms are also summarized.
Data Synchronization in a Network of Coupled Phase Oscillators (2007)

We devised a new method of data mining for a large-scale database. In the method, a network of locally coupled phase oscillators subject to Kuramoto's model substitutes for given multivariate data to generate major features through phase locking of the oscillators, i.e., phase transition of the data set. We applied the method to the national database of care needs certification for the Japanese public long-term care insurance program, and found three major patterns in the aging process of the frail elderly. This work revealed the latent utility of Kuramoto's model for data processing.
Trace metal interactions with microbial biofilms in natural and engineered systems (1988)

Substantial evidence is available indicating that microbial films coat most surfaces in natural aquatic environments. Biofilms are also commonly employed in many engineered wastewater treatment processes. Such films, which consist of attached bacteria and their exopolymers, have substantial metal‐binding properties and are likely to play an important role in the partitioning of toxic metals between surfaces and solutions. In this article, we present a review of findings on attachment and growth of bacterial films, with particular regard to the metal‐binding properties of microbial cell surfaces and extracellular polymeric organic compounds. The review focuses primarily upon direct interactions between transition metals and biofilms under oxic conditions. However, some secondary interactions are considered, such as cell‐ and polymer‐mediated precipitation of Fe or Mn hydrous oxides (which are also active metal scavengers). Other possible secondary interactions, such as those that might occur deep in biofilms where anoxic conditions and sulfate reduction may result in the precipitation of metal sulfides, are excluded in order to limit the scope of the discussion. We also review information on alterations in adsorptive behavior of inorganic surfaces which may result from the presence of biofilms and organic surface coatings of microbial origin. The adsorptive properties of such surfaces are relatively well understood in the absence of microbial modifications, but the properties of biofilm‐modified surfaces are poorly understood. Finally, we attempt to integrate some of the presently available modeling approaches which can be brought to bear on this complex problem.
Growth of CdTe films on alternative substrates by molecular beam epitaxy (1984)

Growth of epitaxial CdTe films on silicon and sapphire substrates is discussed. The quality of the epitaxial CdTe films was determined from x-ray diffraction, UV reflectance, and photoluminescence measurements. CdTe epitaxy was achieved on both silicon and sapphire substrates using growth rates of 1–3 μm/h and substrate temperatures of 200–400 °C. The CdTe/sapphire epilayers, in particular, exhibit exceptional properties including a large photoluminescence at 77 °K, a large photoconductivity at room temperature, majority carrier (electron) lifetimes greater than 10−5 s at 300 K, and electron mobilities greater than 900 cm2/V s at room temperature. These mobilities are the largest ever reported for CdTe films grown by any technique. On the basis of these results, CdTe/sapphire epilayers appear to offer a viable alternative to bulk CdTe substrates for growth of HgCdTe, an important infrared detector material.
