Effectiveness of insoles on plantar pressure redistribution (2004)

For this study, we compared the effectiveness of different design insoles for redistributing pressure during walking for diabetic patients and for normal control subjects. Comparisons of dynamic plantar foot pressure patterns were made with different support, including shoe-only, flat insole, and three contoured insoles. We custom-molded the three contoured insoles by casting the plantar surface of the foot under the conditions of non-weight-bearing, semi-weight-bearing, and full-weight-bearing. With the F-Scan in-shoe system, the interfacial pressure distribution during walking with different plantar supports was measured at 50 Hz for 10 s. The use of insoles could significantly reduce local peak pressure and pressure-time integral and increase the contact area. Contoured insoles were significantly better than flat insoles with regard to the insole functions in reducing local peak pressures. The insole with the semi-weight-bearing foot shape can offer the greatest peak pressure reduction compared to other insole designs, especially for patients with peak pressure located at the second to third metatarsal heads.

A Theory for Rectangular Wings of Small Aspect Ratio (1937)

T theory for flow about wings of large aspect ratio has been worked out rather completely along the lines suggested by Prandtl. This flow is of interest for the main lifting surfaces of present day airplanes. However, for some unconventional airplane wings and especially for the control surfaces of dirigibles, the lifting surfaces have generally a very small aspect ratio and the existing theories have so far been inadequate. Moreover, the dirigible as a whole exhibits very much the same behavior, at least as far as the dynamic lift is concerned, as a wing of small aspect ratio. In view of this, Th. von Karman suggested to the author making a theoretical analysis of wings of small aspect ratio. The first step was the limiting case of a rectangular wing of zero aspect ratio, that is, finite span but infinite chord. Such a wing is hydrodynamically equivalent to a constant distribution of bound vortices whose axes lie along the span (Fig. 1). At the ends of the span these vortices separate, the flow downstream following the resultant velocity vector. The inclination of the vortices to the wing was found to be about half the angle of attack. As an approximation, in order to simplify the calculation of the induced velocities, it was assumed that the trailing vortices formed straight lines at some effective inclination to the wing. This effective inclination was taken equal to the initial angle at which the vortices separate, on the assumption that the part of the vortex nearest the wing is the most influential in inducing downwash at the wing. With this approximation, three important results were obtained for the wing of zero aspect ratio:
Synthesis of (±)-Clavicipitic Acid and Its Derivatives (1994)

A formal total synthesis of (±)-clavicipitic acid was achieved in five steps from indole-3-carboxaldehyde. Syntheses of (±)-4-cyano-, (±)-4-methyl-, and (±)-4-hydroxymethyl-6-(2-methyl-1-propen-1-yl)- 3,4,5,6-tetrahydro-1H-azepino [5,4,3-cd] indoles are also reported
Antidiarrhoeal activity of loperamide: studies of its influence on ion transport across rabbit ileal mucosa in vitro. (1982)

Loperamide is a well-established antidiarrhoeal agent with effects on gastrointestinal motility. We have now shown that the drug influences ion transport. In isolated rabbit ileal mucosa loperamide caused a dose-related fall in potential difference and short-circuit current and reduced the serosa to mucosa flux of chloride. The electrical effects were inhibited by naloxone (10(-6)M) suggesting that they were mediated by opiate receptors. Loperamide (10(-6)M) inhibited secretion provoked by heat stable and heat labile E. coli toxins and by prostaglandin E2. We conclude that loperamide is able to inhibit secretion mediated by cAMP or cGNP, and that this may be relevant to its antidiarrhoeal properties.
High serum levels of CA125 and interleukin‐6 in a patient with Ki‐1 lymphoma (1997)

We report a 53-year-old-man with an aggressive Ki-1 lymphoma who had high serum CA125, a marker protein of the epithelial ovarian cancer, and interleukin-6 (IL-6) concentrations. Both CA125 and IL-6 levels decreased after chemotherapy and elevated with disease progression. The patient's lymphoma cells obtained before chemotherapy grew continuously in vitro, were IL-6 dependent and were found to secrete CA125 in culture medium. These results indicate that CA125 can be secreted by Ki-1 lymphoma cells and IL-6 may promote the growth of Ki-1 lymphoma cells.
3D nanomanufacturing with femtosecond lasers and applications (2007)

One of the rapidly advancing femtosecond laser technologies is three-dimensional micro- and nanostructuring by two-photon polymerization (2PP) technique. This technique allows the fabrication of any computer-generated 3D structure by direct laser "recording" into the volume of a photosensitive material. Because of the threshold behavior and nonlinear nature of the 2PP process, a resolution beyond the diffraction limit can be realized by controlling the laser pulse energy and number of applied pulses. Many different applications of 2PP technique are discussed.
Microwave‐improved polymerization of ϵ‐caprolactone initiated by carboxylic acids (2002)

Abstract The ring‐opening polymerization of ε‐caprolactone (ε‐CL), initiated by carboxylic acids such as benzoic acid and chlorinated acetic acids under microwave irradiation, was investigated; with this method, no metal catalyst was necessary. The product was characterized as poly(ε‐caprolactone) (PCL) by 1 H NMR spectroscopy, Fourier transform infrared spectroscopy, ultraviolet spectroscopy, and gel permeation chromatography. The polymerization was significantly improved under microwave irradiation. The weight‐average molecular weight ( M w ) of PCL reached 44,800 g/mol, with a polydispersity index [weight‐average molecular weight/number‐average molecular weight ( M w / M n )] of 1.6, when a mixture of ε‐CL and benzoic acid (25/1 molar ratio) was irradiated at 680 W for 240 min, whereas PCL with M w = 12,100 and M w / M n = 4.2 was obtained from the same mixture by a conventional heating method at 210 °C for 240 min. A degradation of the resultant PCL was observed during microwave polymerization with chlorinated acetic acids as initiators, and this induced a decrease in M w of PCL. However, the degradation was hindered by benzoic acid at low concentrations. © 2002 Wiley Periodicals, Inc. J Polym Sci Part A: Polym Chem 41: 13–21, 2003
Toward bias minimization in acoustic feedback cancellation systems (2007)

A novel technique for bias suppression within acoustic feedback cancellation systems is proposed. This is achieved based on the use of all-pass filters in the forward part of the hearing aid. The poles of these filters are made time-varying, which results in a frequency response with constant magnitude and varying phase. This is a desired feature of the proposed approach, since the results from human psychoacoustics show that the human ear is not sensitive to moderate phase perturbations. The derivation of the proposed algorithms for the time variation of the location of the poles of all pass filters is based on a rigorous analysis of the phenomenon of bias in acoustic systems. Practical issues, such as the dependence of the steady-state error on the order of the all-pass filter, the number of varying poles, and their standard deviation are examined and strategies for the variation of the poles are introduced. Results obtained from a simulated hearing aid are provided to support the analysis. The quality of the processed audio signals is evaluated through subjective tests.
Preparation of Titania Nanotubes and Their Environmental Applications as Electrode (2005)

Titanium oxide nanotubes were successfully grown from a titanium plate by direct anodic oxidation with 0.2 wt % hydrofluoric acid being the supporting electrolyte. These nanotubes are of uniform size and are well-aligned into high-density arrays. They look like honeywell with the structure similar to that of porous alumina obtained by the same technique. TiO2 anatase phase was identified by X-ray diffraction. Significant blue-shift in the spectrum of UV- vis absorption was observed. The mechanism of the novel, simple, and direct growth of the nanotubes was postulated. To investigate their potentials in environmental applications, degradation of pentachlorophenol (PCP) in aqueous solution was carried out using photoelectrocatalytic (PEC) processes, comparing with electrochemical process (EP) and photocatalytic (PC). A significant photoelectrochemical synergetic effect was observed. The kinetic constant of PEC degradation of PCP using TiO2 nanotubes electrode was 86.5% higher than that using TiO2 film electrode. In degrading PCP, 70% of TOC was removed using the TiO2 nanotubes electrode against 50% removed using TiO2 film electrode formed by sol-gel method in 4 h under similar conditions.

History of materials used for recording static and dynamic occlusal contact marks: a literature review (2013)

In the discipline of prosthetic dentistry it is important not only to examine the occlusion, but to be able to record, store, and transfer the information. Over the years many occlusion testing materials have been used. It has been suggested the clinical recording and transfer of information using waxes and other occlusion recording materials have disadvantages relating to inaccuracy and problems of manipulation. Therefore, there has been introduction of many new systems for recording occlusion contacts to overcome such problems. The correct physiological recovery of occlusion posses as much a challenge as ever for every dentist and technician. Even the smallest high spots measuring just a few microns can cause dysfunctions like temporo-mandibular pain. Occlusal proportions are being constantly changed with every procedure. Therefore, an understanding of the synergy of the teeth in static and dynamic occlusion forms the basis of good dentistry. The purpose of this review article is to give and overview of the various materials and methods that have been used to record occlusal contact marks. Key words:Occlusal contact marks, Occlusion indicators, Occlusion test materials, Occlusion recording materials.
Antibiotic Production by a <i>Roseobacter</i> Clade-Affiliated Species from the German Wadden Sea and Its Antagonistic Effects on Indigenous Isolates (2004)

A strain affiliated with the Roseobacter clade and producing a new antibiotic named tropodithietic acid (L. Liang, Ph.D. thesis, University of Göttingen, Göttingen, Germany, 2003) was isolated from the German Wadden Sea. The compound showed strong inhibiting properties with respect to marine bacteria of various taxa and marine algae. Antibiotic production was found to occur during the complete growth phase. Strain mutants without antagonistic properties appeared several times spontaneously.
Consideration of impact factors on data acquisition for ocean radar with VHF band (2008)

An ocean radar with a VHF band is a useful tool for surveying coastal currents in a wide area. We have conducted a field observation of currents in Ariake Bay, the large inner sea located in the western part of Japan. Although the number of valid data acquired (hereafter, data acquisition) varies temporally and spatially, the mechanism of such variation is not yet well understood. Our aim in this study is to investigate the impact factor affecting data acquisition through field observations of current, salinity and wind in Ariake Bay. As a result, the data acquisition and the maximum measurement distance of the radar decreased owing to the decreases in salinity and wind speed. After receiving much rainfall, the data acquisition decreased rapidly in accordance with the decrease in surface salinity influenced by run-off from adjacent rivers and a flood control dike. Also, when wind speed became less than 2 m/s, the intensity of the signals received was not sufficient for the detection of current velocity. In conclusion, salinity and wind speed are important factors for steady-current observation using ocean radars.
4D motion animation of coronary arteries from rotational angiography (2011)

Time-resolved 3-D imaging of the heart is a major research topic in the medical imaging community. Recent advances in the interventional cardiac 3-D imaging from rotational angiography (C-arm CT) are now also making 4-D imaging feasible during procedures in the catheter laboratory. State-of-the-art reconstruction algorithms try to estimate the cardiac motion and utilize the motion field to enhance the reconstruction of a stable cardiac phase (diastole). The available data offers a handful of opportunities during interventional procedures, e.g. the ECG-synchronized dynamic roadmapping or the computation and analysis of functional parameters. In this paper we will demonstrate that the motion vector field (MVF) that is output by motion compensated image reconstruction algorithms is in general not directly usable for animation and motion analysis. Dependent on the algorithm different defects are investigated. A primary issue is that the MVF needs to be inverted, i.e. the wrong direction of motion is provided. A second major issue is the non-periodicity of cardiac motion. In algorithms which compute a non-periodic motion field from a single rotation the in depth motion information along viewing direction is missing, since this cannot be measured in the projections. As a result, while the MVF improves reconstruction quality, it is insufficient for motion animation and analysis. We propose an algorithm to solve both problems, i.e. inversion and missing in-depth information in a unified framework. A periodic version of the MVF is approximated. The task is formulated as a linear optimization problem where a parametric smooth motion model based on B-splines is estimated from the MVF. It is shown that the problem can be solved using a sparse QR factorization within a clinical feasible time of less than one minute. In a phantom experiment using the publicly available CAVAREV platform, the average quality of a non-periodic animation could be increased by 39% by applying the proposed periodization and inversion method.
<i>In Vivo</i> Characterization of the Drug Resistance Profile of the Major ABC Transporters and Other Components of the Yeast Pleiotropic Drug Resistance Network (1998)

Multidrug resistance (MDR) mediated by broad specificity transporters is one of the most important strategies used by pathogens, including cancer cells, to evade chemotherapy. In the yeast Saccharomyces cerevisiae, a complex pleiotropic drug resistance (PDR) network of genes involved in MDR is composed of the transcriptional regulators Pdr1p and Pdr3p, which activate expression of the ATP-binding cassette (ABC) MDR transporters-encoding genes PDR5, SNQ2, and YOR1 as well as other not yet identified genes. We have screened 349 toxic compounds in isogenic S. cerevisiae strains deleted of PDRS, SNQ2, or YOR1 in different combinations as well as both PDR1 and PDR3. The screen revealed extremely promiscuous, yet limited, and to a large extent overlapping but distinct drug resistance profiles of Pdr5p, Snq2p, and Yor1p. These ABC-MDR transporters mediated resistance to most currently available classes of clinically and agriculturally important fungicides and also to many antibiotics, herbicides, and others. Several classes of compounds were identified for the first time in the drug resistance spectrum of MDR transporters. These are fungicides, such as anilinopyrimidines, benzimidazoles, benzenedicarbonitriles, dithiocarbamates, guanidines, imidothiazoles, polyenes, pyrimidynyl carbinols, and strobilurine analogues; the urea derivative and anilide herbicides; flavonoids, several membrane lipids resembling detergents; and newly synthesized lysosomotropic aminoesters; as well as many others. Identification of compounds showing Pdr1p, Pdr3p-dependent, but Pdr5p-, Snq2p-, and Yor1p-independent toxicity, reflected in the case of rhodamine 6G, by efflux alterations, suggests the involvement of new drug resistance genes and is a first step toward their identification. The highly increased toxicity of bile acids toward the PDR1, PDR3 double disruptant together with the decreased level of BAT1 promoter dependent beta-galactosidase activity suggest that the Bat1p ABC transporter is a new member of the PDR network. Our results may contribute to a better understanding of the mechanism of MDR, in particular in the pathogenic yeast Candida albicans. They also provide and indication of the physiological function of MDR transporters and suggest new approaches for the cloning of the mammalian bile acid transporters.
Implementation of an electronic media security system (2005)

Recent security lapses within the Department of Energy Laboratories prompted the establishment and implementation of additional procedures and training for operations involving classified removable electronic media (CREM) storage. In addition, the definition of CREM has been expanded and the number of CREM has increased significantly. Procedures now require that all CREM be inventoried and accounted for on a weekly basis. Weekly inventories consist of a physical comparison of each item against the reportable inventory listing. Securing and accounting for CREM is a continuous challenge for existing security systems. To address the challenge, Pacific Northwest National Laboratory (PNNL) has developed an automated electronic media security system (EMSS) for a weekly CREM inventory collection and reporting system. The EMSS approach is to tag the CREM with an electronically readable unique identification code and automatically collect data on the inventory in each security container or vault at a user-defined interval and upon detection of an access event, thus eliminating the need for hand-written inventory sheets while allowing automated transfer of the collected inventory data to an electronic reporting system. An electronic log of CREM access events is maintained, providing enhanced accountability for daily/weekly checks, routine audits, and follow-up investigations. The key attributes of the EMSS include improved accountability, reduced risk of human error, improved accuracy and timeliness of inventory data, and reduced costs as a result of man-hour reductions.
Colorectal Cancer or Colon and Rectal Cancer? (2007)

PMDB—a project master database for software engineering environments (1985)

Although the use of Software Engineering Environments (SEE) results in increased software productivity, current SEEs are still in the infant stages and lack critical characteristics such as an integrated project database which stores all data pertinent to a project, i.e., resources, products, management information, etc, and which provides easy access to its data.Driven by projects' needs and motivated by the experiences acquired in the building of the TRW Software Development Environment, an effort was set forth, as part of an Internal Research and Development project, to study the issues associated with an environment database, with the overall objective of defining, designing and developing a Project Master Database (PMDB) as an integrated part of a software development environment. This paper reports the initial results of this work; it describes our PMDB model and discusses some of the technical issues in the definition and design of an environment database.
Solar Power Generation Development (2011)

This project centered on creating a solar cell prototype enabling significant reductions in module cost and increases in module efficiency. Low cost was addressed by using plentiful organic materials that only comprise 16% of the total module cost, and by leveraging building integrated PV concepts that reduce the cost of key module components to zero. High efficiency was addressed by implementing multiband organic PV, low cost spectral splitting, and possibly integrating photovoltaic and photothermal mechanisms. This research has contributed to the design of multiband organic PV, and the sealing of organic PV cells. If one assumes that the aggregate multiband efficiency can reach 12%, projected cost would be $0.97/W. If the sealing technology enables 10 to 20 year lifetimes, the LCOE will match that of domestic coal. The final report describes progress towards these goals.
Case studies on the clinical applications using case-based reasoning (2012)

Case-Based Reasoning (CBR) is a promising Artificial Intelligence (AI) method that is applied for problem solving tasks. This approach is widely used in order to develop Clinical Decision Support System (CDSS). A CDSS for diagnosis and treatment often plays a vital role and brings essential benefits for clinicians. Such a CDSS could function as an expert for a less experienced clinician or as a second option/opinion of an experienced clinician to their decision making task. This paper presents the case studies on 3 clinical Decision Support Systems as an overview of CBR research and development. Two medical domains are used here for the case studies: case_study_1) CDSS for stress diagnosis case_study_2) CDSS for stress treatment and case_study_3) CDSS for postoperative pain treatment. The observation shows the current developments, future directions and pros and cons of the CBR approach. Moreover, the paper shares the experiences of developing 3CDSS in medical domain in terms of case study.
Evaluation of Location-Aware Travel Guide (2009)

The paper describes a location-aware travel guide prototype that was implemented into a Nokia Symbian Series 60 phone with Location API (JSR-179) support. It contains relevant travelling information that could assist users while they are travelling or when they arrive at a particular destination. The objectives of the study were to discover user preferences towards fisheye and list style menus in the user interface as well as user satisfaction on the prototype. A field test to evaluate the prototype was done with participants ranging from 10 to 39 years old. The results indicated that the fisheye style and the prototype itself were easily comprehended and accepted by the participants.
