Architectural Skeletons: The Re-Usable Building-Blocks for Parallel Applications. (1999)

Abstract Design pattern concepts are being used in the various disciplines of computing. In the parallel computing domain, design patterns specify recurring parallel computing problems and their solution strategies. The paper defines a generic (i.e. application and pattern independent) model for realizing and using parallel design patterns. The term architectural skeleton is coined to represent the application independent, generic set of attributes associated with a pattern. The model is aimed at providing many of the functionalities of MPI, plus the benefits of the patterns. The intent is to provide a considerable amount of flexibility to the user in application development. The generic model also enhances usability. As it turns out, the model is a natural candidate for object-oriented style of design and implementation. It is currently implemented as a C++ template-library without requiring any language extension. The generic model, together with the object-oriented and library-based approach, facilitates extensibility (i.e. new patterns can be added to the system library without requiring any major modifications to the existing system).

Computer Vision-Based Approach for Reading Analog Multimeter (2018)

Multimeters are useful instruments for measuring electronic parameters. Even though the digital multimeter is commonly used in our daily life under the considerations of precision and cost, the analog multimeter is still preferable in many applications due to its easy use to monitor promptly varying values. However, the reading of analog multimeters (or A-meter) usually relies on human eyes with two obvious drawbacks of inefficiency and easy fatigue, while visual inspection onto an A-meter is needed for a long period of time. From the viewpoint of optical sensor application, computer vision, like human eyes, can also be used to sense stimuli from the real world. Therefore, in this paper, an approach of reading an A-meter based on a computer vision technique is proposed. Reading an A-meter relies on information from the arrow on the function selector and the pointer on the instrument meter; the presented method is thus mainly composed of horizontal alignment of the A-meter, detection of the instrument meter region, angle detection of the selector arrow, and angle detection of the pointer. In addition, the schemes of edge-based geometric matching (EGM) and pyramidal gradient matching (PGM) are adopted to detect the regions of interest. The mapping relationship between the function selector and the selector arrow as well as that between the instrument meter and the pointer are built and formulated to finally read the A-meter. The often used scenarios for reading AC voltage, DC voltage, and DC current as well as resistance are used for experiments and evaluations. The experimental results show that the accuracy of detecting the function selected is 100%, the mean accuracy of reading a value from the A-meter is 95% or above, except for some cases of reading resistance that are affected by the so-called little-change-large-multiplier effect. The proposed method can perform very well as long as the mean intensity is ≥ 7.5 . Based on a suitable modification of the proposed method, an application of monitoring a storage level meter and pressure meter installed on a 15 m 3 liquid nitrogen (LN2) tank is demonstrated. Our experiments and demonstrations confirm the feasibility of the proposed approach.
Acoustofluidics 6: Experimental characterization of ultrasonic particle manipulation devices (2012)

Because of uncertainties in material and geometrical parameters in ultrasonic devices, experimental characterization is an indispensable part in their successful application for the manipulation of particles or cells. Its miniaturized size precludes the use of many of the usual tools used for macroscopic systems. Also, a further challenge is the fact that the resulting motion due to the electromechanical actuation has both high frequency and small amplitudes. Contactless methods like laser interferometry are therefore promising methods. In addition, as long as there is strong electromechanical coupling between the transducer and the device also electrical measurements like admittance curves give insight into the frequencies at which the devices might work best. This is the case for example for piezoelectric transducers working at one of their resonance frequencies. Because the devices usually are used in resonant modes, narrow frequency detection methods like lock in amplifiers help to improve the signal to noise ratio. Also many analysis tools have been established in the context of modal analysis, which is based on frequency domain methods. Special emphasis is placed here on the determination of the quality factor Q of the resonator, as Q determines the efficiency of a device.
Photogenerating Silver Nanoparticles and Polymer Nanocomposites by Direct Activation in the Near Infrared (2011)

This work reports on an improvement of the photochemically assisted synthesis of silver nanoparticles by direct photoreduction of AgNO 3 with a laser source emitting in the near infrared range (NIR). For this, polymethine dyes were used as the photoactive agents. Both the effects of central chain structure and activation intensity were investigated. The reduction kinetics was followed up by UV‐Vis spectroscopy, and the particles size was evaluated by transmission electron microscopy. The results showed that light intensity affects both the average size and size distribution of Ag nanoparticles generated through this process. The particles can also be generated in situ in a photopolymerizable formulation so that metal/polymer nanocomposites become available through a one‐step photoassisted process on the basis of NIR activation. The process described herein is very fast (seconds to a few minutes), and it readily lends itself to automatization for mass production of micro‐optical elements implemented directly onto integrated NIR sources.
A unified storage layer for supporting distributed workflows in kubernetes (2021)

The distributed computing landscape has been undergoing radical changes: High-Performance Computing (HPC) applications are moving to the Cloud, as a way of simplifying development, deployment, and migration across computing systems. Meanwhile, cloud applications are becoming increasingly complex and computationally intensive, with the advent of High-Performance Data Analytics (HPDA) pipelines --- highly distributed workflows dealing with enormous and diverse datasets, heavily relying on virtualization and containers, that would benefit from technologies used in "traditional" HPC. The foreseeable convergence, demands new abstractions to cope with the increased heterogeneity, so that differing workload classes can coexist seamlessly on the same infrastructure. In this paper, we propose a Unified Storage Layer (USL), to enable cloud-native applications to transparently access a wide spectrum of storage solutions, ranging from high-performance filesystems to cloud-based object stores and key-value databases. Allowing software to exploit the best out of the storage services available with no need for manual intervention from users or programmers, simplifies development and execution of workflows, and boosts overall productivity. This work has been motivated by the requirements of real-world, industry-driven applications running on Kubernetes, the industry standard for cloud infrastructure orchestration.
Kinked Demand Curve (1987)

The theory based on the kinked demand curve can be considered as a particular theory of oligopoly, which sought to provide an explanation for some degree of price rigidity. It was widely believed during the 1930s that the output prices of manufactured goods had been unresponsive to the low levels of demand experienced, which found a reflection in the idea of ‘administered prices’ (Means 1935).

Characterizing human gene splice sites using evolved regular expressions (2006)

In this paper, an algorithm using evolved regular expressions to characterize and predict human gene splice sites without any prior knowledge is described. In contrast to previous pattern-based approaches to the splice site detection problem, the patterns to be matched are unknown in advance and discovered using a supervised learning approach. We have used a genetic programming based system, PerlGP, to evolve regular expressions and proper length windows for a long sequence in which the evolved regular expressions can effectively characterize and predict the splice junctions. Since the gene splicing process is too complex to be fully understood currently, and the widely accepted consensus sequences only reflect some partial statistical information around splice sites, not to mention defining a splice site. However, our evolved regular expressions may shed new light on the underlying rules that define splice sites. Experimental results demonstrate that using the evolved regular expressions, splice junctions could be accurately characterized, furthermore, these evolved regular expressions could also be employed as a predictor to detect whether a CT/AG containing sequence is a splice site or not. Our experimental results also exhibit that the performance of this approach for predicting human gene splice junctions is competitive compared with some other traditional methods.
1,25-Dihydroxyvitamin D<sub>3</sub>Receptors and Hormonal Responses in Cloned Human Skeletal Muscle Cells* (1986)

Although skeletal muscle is a major calcium-regulated organ, there remains uncertainty about whether muscle is a target organ for the action of 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3]. In this study we examine pure populations of clonally derived human muscle cells for the presence of 1,25-(OH)2D3 receptors and direct responses to the hormone. All of the clones tested exhibited specific [3H]1,25-(OH)2D3 binding, with values ranging from 5-70 fmol/mg protein. Scatchard analysis of binding data revealed a dissociation constant (approximately 100 pM) comparable to that of classical receptors in other target organs. The 1,25-(OH)2D3 receptors sedimented at 3.3S on hypertonic sucrose gradients. Specificity for [3H]1,25-(OH)2D3 was demonstrated on gradients by substantially better competition by 1,25-(OH)2D3 than 25-hydroxyvitamin D3 for the 3.3S receptor binding peak. The 1,25-(OH)2D3 receptor complex bound to DNA-cellulose and eluted as a single peak at 0.2 M KCl. Myoblasts and myotubes did not show significant differences in either the amount or characteristics of the 1,25-(OH)2D3 receptor. In addition to the presence of receptors, cells were tested for functional responsiveness to 1,25-(OH)2D3. Both cell types exhibited a dose-dependent induction of 25-hydroxyvitamin D3-24-hydroxylase enzyme activity after treatment of monolayers with 1,25-(OH)2D3. Incorporation of both leucine and thymidine into growing myoblasts and fused myotubes was inhibited in a dose-dependent fashion after treatment with 1,25-(OH)2D3. In summary, cloned human skeletal muscle cells contain a binding protein compatible with classical 1,25-(OH)2D3 receptors as well as functional responsiveness to 1,25-(OH)2D3 at physiological concentrations of hormone.
Persulfide Reactivity in the Detection of Protein <i>S</i>-Sulfhydration (2013)

Hydrogen sulfide (H2S) has emerged as a new member of the gaseous transmitter family of signaling molecules and appears to play a regulatory role in the cardiovascular and nervous systems. Recent studies suggest that protein cysteine S-sulfhydration may function as a mechanism for transforming the H2S signal into a biological response. However, selective detection of S-sulfhydryl modifications is challenging since the persulfide group (RSSH) exhibits reactivity akin to other sulfur species, especially thiols. A modification of the biotin switch technique, using S-methyl methanethiosulfonate (MMTS) as an alkylating reagent, was recently used to identify a large number of proteins that may undergo S-sulfhydration, but the underlying mechanism of chemical detection was not fully explored. To address this key issue, we have developed a protein persulfide model and analogue of MMTS, S-4-bromobenzyl methanethiosulfonate (BBMTS). Using these new reagents, we investigated the chemistry in the modified biotin switch method and examined the reactivity of protein persulfides toward different electrophile/nucleophile species. Together, our data affirm the nucleophilic properties of the persulfide sulfane sulfur and afford new insights into protein S-sulfhydryl chemistry, which may be exploited in future detection strategies.
[Therapeutic aspects of coli mastitis in ruminants]. (1985)

Cows with coliform mastitis showed, in addition to fever, tachycardia and ruminal stasis and a concatenation of nonspecific responses, such as neutrophylic leukopenia followed by leukocytosis, lymphopenia, hypocalcaemia, hypoferraemia, hypozincaemia, and hypercupremia, and changes in the concentration of certain serum proteins. Similar responses occurred in cows and goats when mastitis was induced by an E. coli endotoxin or following the i/v injection of such endotoxin. Research suggested that in cows with clinical mastitis the symptoms of a generalized disease were predominantly the result of the release of phagocyte endogenous proteins at the site of inflammation in the mammary gland. Another inflammatory protein was the leukocytic endothelial mediator which changed the plasma concentrations of trace elements. Local treatment with the rather toxic antibiotic, polymyxin B, blocked the effect of the endotoxin administered via the udder on plasma Zn and Fe values. Therefore, local treatment with this drug seemed to be indicated with cows having E. coli mastitis. Based on pharmacokinetic behaviour parenteral treatment of such cows with trimethoprim or chloramphenicol appeared to be interest. Furthermore fluboprofen, a nonsteroid antiinflammatory agent was shown to possess a beneficial effect in cows with experimental E. coli mastitis.
Hyperthermia and radiation therapy in the treatment of recurrent merkel cell tumors (1988)

A high incidence of local recurrence, spread to regional lymph nodes, and distant metastases has been reported after surgical excision of Merkel cell tumors (MCT). The use of postoperative radiation therapy and/or chemotherapy is reviewed from the literature. Despite adjuvant treatment, local tumor recurrences frequently develop. Two patients are presented with metastatic MCT recurrent in previously irradiated sites who had excellent clinical responses and local control following retreatment with local hyperthermia in conjunction with low to moderate dose radiation therapy. These patients represent the first reported use of hyperthermia in the management of MCT. The encouraging local responses described suggest a potential role for the use of hyperthermia and concomitant radiation therapy in the treatment of recurrent MCT.
Self-regulated GPS navigation processor (2002)

We implement a navigation processor for the stand-alone global positioning system (GPS). We develop a behavior observer to monitor user dynamics and to aid a Kalman filter performing continuous position and speed estimates. The behavior observer consists of a fast observer and a signal detector. The fast observer tracks user maneuvers. The signal detector compares outputs of the fast observer and the Kalman filter to determine user dynamics and corrects operations of the Kalman filter. Simulations using fixed-point arithmetic demonstrate that dramatic improvements on tracking ability can be achieved without degradation in steady-state position accuracy.
Fabrication of Axial and Radial Heterostructures for Semiconductor Nanowires by Using Selective-Area Metal-Organic Vapor-Phase Epitaxy (2011)

The fabrication of GaAs- and InP-based III-V semiconductor nanowires with axial/radial heterostructures by using selective-area metal-organic vapor-phase epitaxy is reviewed. Nanowires, with a diameter of 50–300 nm and with a length of up to 10 μm, have been grown along the<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:mo>〈</mml:mo><mml:mrow><mml:mn>111</mml:mn></mml:mrow><mml:mo>〉</mml:mo></mml:mrow></mml:mrow></mml:math>B or<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"><mml:mrow><mml:mrow><mml:mo>〈</mml:mo><mml:mrow><mml:mn>111</mml:mn></mml:mrow><mml:mo>〉</mml:mo></mml:mrow></mml:mrow></mml:math>A crystallographic orientation from lithography-defined SiO 2 mask openings on a group III-V semiconductor substrate surface. An InGaAs quantum well (QW) in GaAs/InGaAs nanowires and a GaAs QW in GaAs/AlGaAs or GaAs/GaAsP nanowires have been fabricated for the axial heterostructures to investigate photoluminescence spectra from QWs with various thicknesses. Transmission electron microscopy combined with energy dispersive X-ray spectroscopy measurements have been used to analyze the crystal structure and the atomic composition profile for the nanowires. GaAs/AlGaAs, InP/InAs/InP, and GaAs/GaAsP core-shell structures have been found to be effective for the radial heterostructures to increase photoluminescence intensity and have enabled laser emissions from a single GaAs/GaAsP nanowire waveguide. The results have indicated that the core-shell structure is indispensable for surface passivation and practical use of nanowire optoelectronics devices.
Liposome-encapsulated-gentamicin therapy of Mycobacterium avium complex infection in beige mice (1990)

Efficacy of liposome-encapsulated amikacin and free amikacin against Mycobacterium avium complex was evaluated in the beige mouse (C57BL/6J-bgJ/bgJ) acute infection model. Approximately 10(7) viable M. avium complex serotype 1 cells for which the MIC of amikacin was 8 micrograms/ml were given intravenously. Treatment was started with encapsulated or free amikacin at approximately 110 or 40 mg/kg of body weight 7 or 14 days later. In the former experiment, treatment was given two or three times per week. In the latter experiment, treatment was given daily for 5 days. The animals were sacrificed 5 days after the last dose. Liver, spleen, and lung were homogenized, and viable cell counts were determined on 7H10 agar. An analysis of variance and subsequent Tukey HSD (honestly significant difference) tests indicated that both encapsulated and free amikacin significantly reduced viable cell counts in each of the organs compared with counts in the control group. Compared with free amikacin, encapsulated amikacin significantly reduced viable cell counts in the liver and spleen. Liposome encapsulation of an active agent appears to be a promising therapeutic approach to M. avium complex infection.
Assessing the applicability of fault-proneness models across object-oriented software projects (2002)

A number of papers have investigated the relationships between design metrics and the detection of faults in object-oriented software. Several of these studies have shown that such models can be accurate in predicting faulty classes within one particular software product. In practice, however, prediction models are built on certain products to be used on subsequent software development projects. How accurate can these models be, considering the inevitable differences that may exist across projects and systems? Organizations typically learn and change. From a more general standpoint, can we obtain any evidence that such models are economically viable tools to focus validation and verification effort? This paper attempts to answer these questions by devising a general but tailorable cost-benefit model and by using fault and design data collected on two mid-size Java systems developed in the same environment. Another contribution of the paper is the use of a novel exploratory analysis technique - MARS (multivariate adaptive regression splines) to build such fault-proneness models, whose functional form is a-priori unknown. The results indicate that a model built on one system can be accurately used to rank classes within another system according to their fault proneness. The downside, however, is that, because of system differences, the predicted fault probabilities are not representative of the system predicted. However, our cost-benefit model demonstrates that the MARS fault-proneness model is potentially viable, from an economical standpoint. The linear model is not nearly as good, thus suggesting a more complex model is required.

Infoethics for Leaders: Models of Moral Agency in the Information Environment. (1992)

INFOETHICS, THE ETHICS OF information systems, can offer insights and methods to understand the problems which leaders in the information professions face. As moral agents (ethical selves) who assume responsibility in their personal, private, professional, and public lives, information professionals balance conflicting loyalties. In the workplace, they negotiate between the ideals and realities of their institutions and of the profession in making decisions. In the global information environment, leaders will be needed to use the tools of ethical analysis for shaping policy.
