High-sensitivity broadband microwave spectroscopy with small nonresonant coils (1986)

The use of a small, nonresonant, coil of μm dimensions as the microwave magnetic field structure of a broadband electron-spin-resonance (ESR) spectrometer is described. The coil is driven by a broadband microwave generator which operates between 0.1 and 8.5 GHz. The samples may fill the coil to approximately 100%. It is shown that for small size samples this system offers higher sensitivity than a conventional cavity spectrometer. Because the system is broadband, either frequency scans or the conventional magnetic field scans can be used to traverse the resonance. Examples for DPPH and for the spin glass AgMn using this method are reported. Since the sample coil is small, it has many potential applications, such as insertion into the mixing chamber of a dilution refrigerator or high-pressure cell, efficient use of power in ENDOR and other double resonance experiments, and rapid recovery from transients in pulsed ESR experiments.
Hyperviscosity caused by hyaluronic acid in serum in a case of Wilms' tumor. (1984)

We describe the case of a three-year-old girl with Wilms' tumor, whose serum showed at least a fivefold increase in relative viscosity although concentrations of albumin and immunoglobulins were normal. An unusual electrophoretogram of serum protein prompted further investigation. The increased viscosity was caused by the presence of high concentrations of hyaluronic acid, a glycosaminoglycan normally not detectable in serum.

Signal Acquisition and Analysis of Shaft Unbalance Vibration Test (2014)

This paper simulated the unbalance vibration conditions by the vibration test platform, measuring some common characteristic parameters of unbalance vibration fault diagnosis. This paper chose the time-domain analysis method, processing the characteristic parameters of the test, so as to achieve the purpose of vibration diagnosis. Through a large number of experimental data, this paper verified the feasibility and the effectiveness of the proposed approach to the unbalance fault diagnosis. The method proposed in this paper not only can be applied to unbalance fault diagnosis, but also can be promoted to apply to the fault diagnosis of other rotating machinery.

Customer experience places: the new offering frontier (2002)

Marketing flounders at many companies today, as people have become relatively immune to messages broadcast at them. The way to reach customers is to create an experience they can participate in and enjoy, the new offering frontier. To be clear, this article is not about “experiential marketing” – that is, giving marketing promotions more sensory appeal by adding imagery, tactile materials, motion, scents, sounds, or other sensations. Rather, as a key part of their marketing programs companies should create experience places – absorbing, entertaining real or virtual locations – where customers can try out offerings as they immerse themselves in the experience. Companies should not stop at creating just one experience place; marketers should investigate the location hierarchy model to learn how to design a series of related experiences that flow one from another, creating demand up and down at every level. These various real and virtual experiences generate new forms of revenue and drive sales of whatever the company currently offers. When experience places are done well, potential customers can’t help but pay attention – and the leading companies find that customers are willing to pay for the experiences.
Volumetric Visualization Of NEXRAD Level II Doppler Weather Data From Multiple Sites (2007)

Weather visualization is critical for operational forecasters and weather researchers to analyze, monitor, and predict severe weather events such as storms, tornadoes, and hurricanes. Usually measured weather datasets such as NEXRAD Level II radar data contain some errors and have temporal aliasing issues, so that the raw data cannot represent the true meteorological patterns. Existing weather visualization packages usually ignore these problems, thus they fail to unveil some detailed information and cannot meet the needs of professional meteorologists. Most displays generated by those packages are limited to 2D images, 3D point clouds, or iso-surfaces. Those displays are not able to accurately represent the details of the data. The limitation of visualizing data from a single radar site at one single time step in most packages blocks desirable information in the datasets. We developed an efficient and accurate visualization tool capable of displaying the long-track 3D NEXRAD Level II volumetric weather data from multiple sites. The data were captured and integrated from three sites (KEAX, KILX and KSLX), and rendered by using the hardware-accelerated volume-rendering technique. Customized transfer functions are also provided for users to map data values to optical properties such as color and opacity to create different views. We also implemented a compression algorithm to compress 3D textures in order to largely reduce the consumption of hard disk space and to enhance the rendering speed without degrading image quality. An example study shows the tracking of a 24-hour supercell storm observed on March 12, 2006, in the Midwest of the United States. Images and animations from our implementation coupled with results from a set of experiments demonstrate that our methods and approaches are fast and robust, making them suitable for processing and rendering huge amounts of Doppler Level II weather data from multiple stations.
Testing for Faults in Wiring Networks (1974)

An algorithm is derived for multiprobe testing for shorts, opens, and wiring errors in any multiterminal wiring network, such as a printed circuit board, wiring harness, multiconductor cable, or backplane wiring board. For behavioral testing the minimum number of tests required, always achievable, is equal to p - 1 + [log <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> q], where p is the number of terminals in the largest interconnected cluster in the network, and q is the total number of clusters, including isolated terminals. For structural testing the number of tests required is less, and can be as small as [log <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> q] + 1 depending upon the assumptions made regarding the types of faults that can occur.
An embedded hardware architecture for GPC-on-Chip applied to automotive active suspension systems (2011)

This paper presents a hardware architecture for an embedded real-time generalized predictive control (GPC) algorithm based on the state-of-the-art Customizable Advanced Processor (CAP9) technology from Atmel; targeting automotive active suspension systems. The GPC algorithm relies on the solution of an optimization problem at every sampling period. Profiling shows that matrix operations consume the largest portion of the computation requirements of the algorithm. The proposed embedded system utilizes a systolic-array based matrix co-processor in order to accelerate matrix operations. The proposed embedded system is designed to fit within the proposed platform while meeting tight real-time constraints imposed by the automotive active suspension systems.
Schrittweise synthesen und eigenschaften einiger cyclopentamerer aus methylenverbrückten (5‐alkyl‐2‐hydroxy‐1,3‐phenylen)‐bausteinen (1981)

Abstract Three cyclopentamers ( 2a–c ) and a chainlike pentanuclear oligomer ( 3a ) were prepared by stepwise syntheses. The molecules of the cyclic compounds with 20 links contain o , o ′‐methylene bridged 2‐hydroxy‐5‐methyl‐1,3‐phenylene or 2‐hydroxy‐5‐ tert ‐butyl‐1,3‐phenylene units in a strictly defined manner. The properties of the cyclic pentamer 2a and the chainlike pentanuclear oligomer 3a were compared. They differ by their solubilities, melting points, IR and 1 H NMR spectra (pseudorotation) and fragmentation behaviour shown by their mass spectra. The pseudorotation of the cyclic compounds were quantitatively studied.
Evolving high speed packet capabilities in a distributed switching system (2003)

A brief description is given of the principles outlined in CCITT recommendation X.31, which constitutes the first point of reference for the integration of packet services in the narrowband integrated-services digital network (ISDN). The architectural problems that arise when trying to integrate the new narrowband and broadband packet services into ISDN. Remarks are made concerning ISDN developments carried out by Italtel. These developments confirm that distributed switching exchanges, such as the LINEA UT, are able to provide narrowband and, later on, broadband ISDN services by adding new hardware and software modules to the basic configuration.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Die Datenbankzugriffssprache SQL (2000)

Im letzten Kapitel wurden relationale Datenbanken vorgestellt. Wir haben gesehen, dass diese Datenbanken ausschließlich aus Tabellen aufgebaut sind, die mit Daten gefüllt werden. Wir haben aber auch gesehen, dass Zusammenhänge zwischen diesen Tabellen mittels Fremdschlüssel hergestellt werden, woraus sich schließlich vielfältige Möglichkeiten der Abfrage und Manipulation ergeben. Aufgabe dieses Kapitels ist es nun zu zeigen, wie mit Hilfe einer Zugriffssprache auf diese Daten in ihrer gesamten Vielfalt zugegriffen werden kann, und wie diese Daten manipuliert werden. Die in Kapitel 3 vermittelten wichtigen theoretischen Grundlagen werden dabei in die Praxis umgesetzt.
Novel Mechanism of Vasodilation in Inflammatory Bowel Disease (2005)

In arterioles from IBD patients, Ach-mediated dilation shifts from endothelial production of NO and EDHF to nonendothelial generation of a PG, likely PGD2. This is a novel dilator mechanism arising from nonendothelial vascular tissue that compensates for loss of endothelium-dependent dilation. PGD2 appears to be important in regulating mucosal blood flow in patients with IBD, implicating potentially detrimental effects from nonsteroidal antiinflammatory drugs.

Don't queue up! (2012)

Public terminals for service provision provide high convenience to users due to their constant availability. Yet, the interaction with them lacks security and privacy as it takes place in a public setting. Additionally, users have to wait in line until they can interact with the terminal. In comparison to that, personal mobile devices allow for private service execution. Since many services, like with-drawing money from an ATM, require physical presence at the terminal, hybrid approaches have been developed. These move parts of the interaction to a mobile device. In this work we present the results of a four week long real world user study, in which we investigated whether hybrid approaches would actually be used. The results show that users accept the hybrid service as they understood that they could use down downtimes (like bus rides) to prepare the interaction with the public terminal. Our findings give novel insights about security relevant aspects such as where and when users interact with the mobile service before accessing the public terminal. So the preparation of the transaction on the mobile phone was often conducted much further away from the terminal than expected (81.0% with a distance greater than 400m) and earlier than expected (82.1% at least 5 minutes in advance).

High Resolution Imaging of Satellites with Ground-Based 10-m Astronomical Telescopes (2007)

High resolution imaging of artificial satellites can play an important role in current and future space endeavors. One such use is acquiring detailed images that can be used to identify or confirm damage and aid repair plans. It is shown that a 10-m astronomical telescope equipped with an adaptive optics system (AO) to correct for atmospheric turbulence using a natural guide star can acquire high resolution images of satellites in low-orbits using a fast shutter and a near-infrared camera even if the telescope is not capable of tracking satellites. With the telescope pointing towards the satellite projected orbit and less than 30 arcsec away from a guide star, multiple images of the satellite are acquired on the detector using the fast shutter. Images can then be shifted and coadded by post processing to increase the satellite signal to noise ratio. Using the Keck telescope typical Strehl ratio and anisoplanatism angle as well as a simple diffusion/reflection model for a satellite 400 km away observed near Zenith at sunset or sunrise, it is expected that such system will produced > 10{sigma} K-band images at a resolution of 10 cm inside a 60 arcsec diameter field of view. If implemented, such camera could deliver the highest resolution satellite images ever acquired from the ground.
Lipidaemic effects of tocotrienols, tocopherols and squalene: studies in the hamster. (1997)

Syrian Golden hamsters have been widely used as a experimental model for the investigation of the aetiology and development of atherosclerosis and cardiovascular disease. The responses of the hamster to dietary fat manipulations are in many ways similar to that observed in humans. The lipidaemic effect of a tocotrienol rich fraction (TRF) from palm oil on human trials has not been consistent. In this study, the cholesterolaemic effect of tocotrienols and tocopherols were differentiated by using pure tocotrienols (that were isolated from palm oil fatty acid distillate) and pure commercial tocopherols and squalene. A palm oil triacylglycerol fraction (POTG), free of all unsaponifiable matter, was used as the dietary fat in different feeding experiments. Tocotrienols added at 162 ppm to POTG (POTG-T3L) significantly (p<0.05) lowered serum total cholesterol (TC) level as compared to that of the POTG group; but the serum LDL-C , HDL-C and TG levels of the POTG-T3L group were not significantly lower than that of the POTG group (P>0.05). Increasing the level of tocotrienol supplementation to the diet (POTG-T3H) appeared to raise rather then reduce the serum TC, LDL-C and HDL-C levels as compared to that of POTG-T3L group. This observation that lower level of tocotrienol supplementation appeared to exhibit stronger hypocholesterolaemic effect than a higher level of tocotrienol supplementation is interesting; but its explanation is not yet forthcoming. When tocopherols were supplemented at 72 ppm to the POTG diet it was observed that the serum TC, LDL-C and HDL-C levels were all somewhat increased when compared to that of the POTG group. These results suggest that tocotrienols and tocopherols may have opposite cholesterolaemic effects in the hamster, and further experiments need to clarify the mode of action of these vitamin E isomers. In our second series of experiments the cholesterolaemic effects of tocotrienols and tocopherols were studied in the presence of squalene, a key intermediate in the cholesterol synthesis pathway and a controversial cholesterol lowering agent. Squalene added to the diet at 0.1% level significantly lowered (p<0.05) serum TC level when compared to that of the POTG group. The LDL-C, HDL-C and TG levels appeared to be lowered by the squalene supplementation also but the differences between the POTG-SQ and POTG groups were not statistically significant (P>0.05). When tocotrienols or tocopherols were added to the squalene-containing POTG diets, the serum TC and LDL-C levels were further reduced (p<0.01) when compared to that of the POTG and POTG-SQ groups. The HDL-C and TG levels were not affected by tocotrienol or tocopherol supplementation in the presence of squalene. These results indicate that in the presence of tocotrienols and squalene POTG exhibit hypocholesterolaemic action whereas tocopherols may have a hypercholesterolaemic effect in the hamster.
Enzyme catalysed hydrolysis of chlorophenoxypropionates (1988)

We report on the enzymatic hydrolysis of methyl 2-phenoxypropionate and of the following chlorinated derivatives: methyl o-chloro-, m-chloro-, p-chloro-, and o,p-dichloro-2-phenoxypropionates. α-Chymotrypsin, lipase, and pig liver esterase have an R enantioselectivity whereas subtilisin has an S enantioselectivity. Enantiomeric excesses (e.e.) cover a wide range (from 5 to 100%).
Serological markers for melanoma (2000)

We present a review of current literature concerning the significance of serological markers in melanoma patients. Results for cytokines, cytokine receptors, cell adhesion molecules, S100 protein, melanoma inhibitory activity, tissue-specific reverse transcription-polymerase chain reaction, neurone-specific enolase, lipid-bound sialic acid and melanin metabolites such as 5-S-cysteinyldopa and 6-hydroxy-5-methoxyindole-2-carboxylic acid are discussed. For most of these substances, serum levels are more pronounced in the more advanced stages of disease. Therefore, these markers seem to have no place in the early detection of melanoma. On the other hand, sensitivity in the advanced stages of disease seems to be < 100%, compromising their use as a new staging procedure. Some markers show promising results as a possible prognostic factor in the early detection of disease progression or in the prediction of therapy outcome. If confirmed by further studies, this could direct future therapeutic strategies and could help to select patients who would benefit most from more aggressive (adjuvant) therapies. In addition, the study of some of these substances could add to the knowledge of tumour biology and immunology.

The accuracy of CT in the staging of carcinoma of the prostate (1987)

Previous studies have reported the accuracy of CT in distinguishing stages of prostatic carcinoma, but they lack uniform surgical proof of histopathologic stage. We evaluated CT scans in 32 patients who underwent radical prostatectomy to assess its role in the preoperative staging of prostatic carcinoma. Two experienced radiologists blindly interpreted CT scans of the pelvis; they looked for evidence of tumor beyond the prostatic capsule and involvement of the seminal vesicles (stage C) or involvement of pelvic lymph nodes (stage D). Sixty-four interpretations in 32 patients yielded a specificity of 75% for predicting stages A or B disease (local disease), a sensitivity of 50% for the prediction of stages C or D, and an overall accuracy of staging of 67%. Interpretation errors were due to an inability to detect lymph node metastases, errors in evaluating the seminal vesicles, and errors in interpreting densities surrounding the prostate gland. Our data suggest that CT should not be used to influence decisions concerning surgical vs nonsurgical treatment in patients with clinically staged local disease and is only useful when unsuspected metastatic nodal disease is detected.
