Fixation of Three-Part Proximal Humeral Fractures: A Biomechanical Evaluation (2000)

In a cadaveric model of three-part proximal humerus fractures stripped of soft tissue, plate/screws fixation and IM nailing provide greater torsional and bending stiffness than does fixation with TBW/Enders nail. There was no statistically significant difference in torsional or bending stiffness between IM nailing with interlocks and plate/screws fixation in this model.
Generation and disposal of petroleum processing waste that contains mercury (1999)

Abstract The origins and fate of mercury found in hydrocarbons are discussed from the perspective of waste minimization, treatment and disposal. Mercury is a common and naturally occurring component of petroleum. Petroleum processing often is accompanied by generation of waste streams that contain some mercury. These waste streams become problematic when the mercury concentration in process feeds exceeds a few ppb because of the highly toxic nature of mercury. Waste is minimized by mercury removal systems that are now prevalent for many processes, but the main incentive to employ such systems is to protect equipment and catalysts. The removal systems have varied waste disposal consequences depending on their chemical properties and process location. Absent mercury removal systems, mercury contamination results in sludge, sediments, contaminated treatment fluids and a variety of other waste streams that must be carefully controlled, segregated and treated for disposal. Waste containing mercury is characterized by chemical analysis that is capable of speciating the various forms of mercury and mercury compounds so as to be able to select treatment and disposal options. In many locations where the mercury concentration in process feeds is high, treatment systems for mercury are not readily available resulting in storage of toxic material for long periods of time. Both chemical and thermal treatment systems are commercially available, but access to cost effective treatment is extremely limited in the petroleum industry.
Induction of an auto-anti-IgE response in rats. IV. Effects on mast cell degranulation. (1993)

Induction of an auto-anti-IgE (auto-aIgE) response in the rat inhibits both total and specific IgE production and alters the distribution of mast cell (MC) subpopulations identified by differential Alcian blue/safranin staining. We have extended these observations by characterizing the auto-aIgE antibodies and determining their effects on MC degranulation in vitro and in vivo. An auto-aIgE response was induced in bacillus Calmette-Guérin (BCG)-primed rats by injecting a conjugate of highly purified rat IgE myeloma (IR2) coupled to tuberculin-derived purified protein derivative (PPD). Anti-IgE autoantibodies were almost exclusively IgG2a. The intradermal injection of auto-aIgE into untreated rats induced local MC degranulation as shown by a strong immediate skin response. Histologically there was evidence of significant degranulation of safranin staining connective tissue MC (SMC) in the skin but not of the Alcian blue staining MC (ABMC) in the sub-epidermal region. The induced degranulation was epsilon-chain specific; immunopurified anti-idiotypic antibodies raised to the IgE IR2 myeloma had no MC degranulating activity. When administered locally, auto-aIgE inhibited a subsequent passive cutaneous anaphylaxis (PCA) response elicited by anti-ovalbumin IgE. In addition, the PCA response was significantly decreased in animals with an ongoing auto-aIgE response. Immunopurified auto-aIgE also induced histamine release in vitro from rat peritoneal MC. These results are discussed in the context of naturally occurring autoantibodies to IgE present in patients with allergic disease.
Efficient Antibody Production upon Suppression of O Mannosylation in the Yeast <i>Ogataea minuta</i> (2007)

When antibodies were expressed in the methylotrophic yeast Ogataea minuta, we found that abnormal O mannosylation occurred in the secreted antibody. Yeast-specific O mannosylation is initiated by the addition of mannose at serine (Ser) or threonine (Thr) residues in the endoplasmic reticulum via protein O mannosyltransferase (Pmt) activity. To suppress the addition of O-linked sugar chains on antibodies, we examined the possibility of inhibiting Pmt activity by the addition of a Pmt inhibitor during cultivation. The Pmt inhibitor was found to partially suppress the O mannosylation on the antibodies. Surprisingly, the suppression of O mannosylation was associated with an increased amount of assembled antibody (H2L2) and enhanced the antigen-binding activity of the secreted antibody. In this study, we demonstrated the expression of human antibody in O. minuta and elucidated the relationship between O mannosylation and antibody production in yeast.
Dimensional metrology in the macroscopic range with sub-nanometre resolution (2013)

Nanomeasuring machines are devices for solving various positioning and measuring problems in a range of several millimetres with sub-nanometre resolution. These devices are used for positioning, probing and measurements. The combination of this machine with a scanning force microscope leads to improved quality in the calibration of standards. The measurement accuracy and stability of the scanning force microscope are important for the achievable measurement uncertainty. Many systems are influenced by the creep, hysteresis and bending of the included piezo actuators. A scanning force microscope head with a combined deflection detection system that comprises an interferometer and a beam deflection system was developed. Due to this system, it is possible to simultaneously measure the displacement, bending and torsion of the cantilever with only one focussed beam. An additional high-speed piezoelectric actuator for the vertical motion of the cantilever was integrated and is controlled by the bending signal. The outcome of this additional control system is a much higher scan speed. The interferometer system can be used for precise measurement of the vertical cantilever motion. Hence, non-linearity and hysteresis in the actuator do not affect the measurement. The device was used for several calibration measurements on step height and lateral standards. This article deals with the set-up, function and application of a scanning force microscope head for dimensional metrology with the nanomeasuring machines.
Agglutinin Responses to Salmonella pullorum in Japanese Quail Selected for Plasma Cholesterol Response to Adrenocorticotropin and a Model Describing the Dynamics of the Response (1984)

Japanese quail from the S16 generation of lines selected for high (HR) and low (LR) plasma cholesterol response to adrenocorticotropin (ACTH), and the randombred control line (C) from which the selected lines had been derived, were immunized with a heat-killed Salmonella pullorum antigen. Plasma from blood samples taken at 0,5,8, and 12 days postimmunization was titered for total agglutinin levels. A quadratic equation and its first derivative, calculated for each bird, produced mean values by line for maximum titers, mean day of maximum titer, and rate of titer decline. Results indicated that the LR line had significantly lower titers than the HR or C lines but that the HR line reached maximum titer later than the LR line. The rate of titer decline was fastest in the C line.
A 3D Plane Recognition Algorithm Based on Image Matching (2012)

The three-dimensional(3D) plane-recognition technology is the basic research of 3D object matching, 3D scene modeling and scene segmentation. Traditional algorithms rely on specific devices and particular environment or the priori calibration parameters. The algorithm fails completely when lose those information. For the shortcomings of the traditional algorithms, the 3D multi-plane detection algorithm based on image matching has been found. It only requires two pictures from different perspective for a project to identify objects' different planes. The algorithm's operation is simple, adaptable and flexible. The algorithm is a new algorithm for 3D plane recognition, and the effectiveness of the algorithm has been verified by experiments.
Hierarchically order porous lotus shaped nano-structured MnO2 through MnCO3: chelate mediated growth and shape dependent improved catalytic activity (2013)

Design of hierarchical nanostructures towards a specific morphology is an important research area due to their shape dependent properties. Here, 3D hierarchically assembled lotus shaped porous MnO2 is synthesized using a simple aqueous solution based chelating agent (citric acid) mediated growth of MnCO3 followed by calcination at 350 °C. MnCO3 in other shapes, such as rods, spheres and nano-aggregates, is also synthesized just by varying the chelating agents. It is observed that the geometry and strength of the chelating ligands has a crucial role in the controlled shape selective synthesis and based on this a probable chelating agent driven formation mechanism is discussed. The synthesized porous MnO2 shapes exhibit excellent shape dependent catalytic oxidation of α-pinene to verbenone using molecular oxygen as the oxidant. The lotus shaped porous MnO2 shows superior activity, with 94% conversion of α-pinene and 87% selectivity of verbenone, to that of other MnO2 shapes. The activity is reasonably high compared to heterogeneous as well as homogeneous catalysts reported in the literature and bulk MnO2 with respect to both their conversion and selectivity. The synthesized lotus shaped MnO2 also showed good catalytic activity towards oxidation of allylic compounds to corresponding ene–ones using molecular oxygen as oxidant and is reusable.
Functional analysis of the Ca(2+)-regulated hemolysin I operon of Actinobacillus pleuropneumoniae serotype 1 (1992)

The genetic determinant encoding the synthesis and secretion of hemolysin I (HlyI; gene designation, hlyI) by Actinobacillus pleuropneumoniae serotype 1 4074T was cloned in the lambda vector EMBL4. A 10.2-kb fragment that encoded hemolytic activity in the phage lysate was aligned by Southern blot hybridization to genes hlyC, hlyA, hlyB, and hlyD of the Escherichia coli hemolysin operon, and expression of the A. pleuropneumoniae genes in E. coli revealed that they have the same functions as their E. coli analogs: hlyIC encodes a protein that activates inactive 105-kDa prohemolysin I (encoded by hlyIA) to active hemolysin I, while hlyIB and hlyID are necessary for HlyIA secretion. Northern (RNA) hybridization of A. pleuropneumoniae RNA revealed that the gene cluster is transcribed as two RNA species, a major one of 3.5 kb, corresponding to hlyICA, and a second, minor one of 7.5 kb, corresponding to the whole operon, hlyICABD. The level of hlyI mRNA was substantially higher in A. pleuropneumoniae 4074T cells grown in the presence of Ca2+, supporting the view that the expression of the hlyI determinant is Ca2+ regulated. Parallel RNA hybridization with random gene probes suggested that this Ca2+ regulation is specific for the hlyI determinant.
The CloudLightning approach to cloud-user interaction (2017)

Deploying applications which require computational power or data intensive capabilities into a cloud environment might became overwhelming, due to the diversity of cloud services and resources. CloudLightning allows users to design their application topology and deploy it without the need for selecting the most suitable resources. The task of finding the resources for an application is taken care of by the CloudLightning self-organizing self-management component. In this paper we describe the functionality of the Gateway Service, the component that enables users to access the CloudLightning functionality.
Information Content Weighting for Perceptual Image Quality Assessment (2010)

Many state-of-the-art perceptual image quality assessment (IQA) algorithms share a common two-stage structure: local quality/distortion measurement followed by pooling. While significant progress has been made in measuring local image quality/distortion, the pooling stage is often done in ad-hoc ways, lacking theoretical principles and reliable computational models. This paper aims to test the hypothesis that when viewing natural images, the optimal perceptual weights for pooling should be proportional to local information content, which can be estimated in units of bit using advanced statistical models of natural images. Our extensive studies based upon six publicly-available subject-rated image databases concluded with three useful findings. First, information content weighting leads to consistent improvement in the performance of IQA algorithms. Second, surprisingly, with information content weighting, even the widely criticized peak signal-to-noise-ratio can be converted to a competitive perceptual quality measure when compared with state-of-the-art algorithms. Third, the best overall performance is achieved by combining information content weighting with multiscale structural similarity measures.

It operates at 2856MHz handling 7MW peak and 5kW average power and offering 25dB isolation and VSWR of 1.1:1. It is designed for application in S-band high energy radiation system.
Effect of strontium nitride on the properties of Sr<sub>2</sub>Si<sub>5</sub>N<sub>8</sub>:Eu<sup>2+</sup>red phosphor (2011)

The nitride phosphor Sr2Si5N8:Eu2+ was synthesized by the high temperature solid-state method. The properties of Sr2Si5N8:Eu2+ were discussed by X-ray diffraction (XRD) scanning electron microscope (SEM) and spectra analysis. The XRD pattern shows that the single phase produces when strontium nitride is a bit excessive. The SEM photo implies that the excessive strontium nitride works as a flux in the reaction system. The position of emission peak is also located at about 612 nm as strontium nitride is excessive. The luminescent intensity of the phosphor adding excessive strontium nitride is higher than that of the phosphor introducing stoichiometric strontium nitride. The optimized content of nitride strontium was 2.05 mol/mol for the obtained phosphor with excellent properties.

Electromagnetic modeling and signal integrity simulation of power/ground networks in high speed digital packages and printed circuit boards (1998)

The electromagnetic modeling and parameter extraction of digital packages and PCB boards for system signal integrity applications are presented. A systematic approach to analyze complex power/ground structures and simulate their effects on digital systems is developed. First, an integral equation boundary element algorithm is applied to the electromagnetic modeling of the PCB structures. Then, equivalent circuits of the power/ground networks are extracted from the EM solution. In an integrated simulation scheme, the equivalent circuits are combined with signal nets, package models, device circuits, and other external circuitry for system level signal integrity analysis and simulation. This methodology has been implemented as software tools and applied to practical design problems. Effects related to power/ground networks, such as simultaneous switching noises, crosstalk, and ground discontinuity are analyzed for realistic designs.
Delegation Issuing Service (2005)

This paper describes the concept of a delegation issuing service (DIS), which is a service that issues X.509 attribute certificates on behalf of an attribute authority (typically a manager). The paper defines the X.509 certificate extensions that are being proposed for the 2005 edition of X.509 in order to implement the DIS concept, as well as the additional steps that a relying party will need to undertake when validating certificates issued in this way. The paper also presents our initial experiences of designing a DIS to add to the PERMIS authorization infrastructure. The paper concludes by reviewing some of the previous standards work in delegation of authority and anticipating some of the further standardization work that is still required in the field of privilege management.
Drug-induced piloerection in man: an alpha 1-adrenoceptor agonist effect? (1986)

The physiology of piloerection is described and clinical experience is discussed. The objective and subjective evidence for drug-induced piloerection by a number of drugs is given and, where it is known, their pharmacological mechanism is described. The results are considered in relation to the hypothesis that drug-induced piloerection is only produced by drugs with alpha 1-adrenoceptor agonist activity. For those drugs without the latter activity where piloerection is supported only by subjective evidence it is suggested that objective evidence should be sought. The fact that there is no objective evidence that the classical alpha 1-adrenoceptor agonist, phenylephrine, produces piloerection is found surprising and it is suggested that such evidence should be sought. If it is found that phenylephrine does not produce piloerection, then the possibility of the existence of a further alpha-agonist subgroup needs to be considered.
DSP implementation of successive interference cancellation (SIC) receiver for 3GPP WCDMA uplink transmission (2003)

Abstract The 3GPP WCDMA is a widely accepted third‐generation cellular system standard. By using nonorthogonal codes for different users, the multiple access interference (MAI) can be a limiting factor for system performance, as for other CDMA systems. Multiuser detection (MUD) is known to reduce MAI and improve CDMA system performance, but many such techniques have high complexity. Successive interference cancellation (SIC) is an effective MUD technique with relatively low complexity. We consider the software implementation of an SIC receiver for WCDMA uplink transmission on a commercially available general‐purpose multi digital signal processor (DSP) platform. This also goes in line with the recent interest in software‐defined radio. Issues addressed in this work include job partitioning and signal routing for multiprocessor implementation, design of SIC components (especially the channel estimator and the signal regenerator), determination of the precision of fixed‐point computations, consideration of the receiver's error performance and analysis of the implementation's complexity and efficiency. These issues are tightly coupled with the 3GPP WCDMA specifications. Because the employed platform only contains four DSPs, the implementation only considers up to three users. But this is sufficient for us to appreciate various DSP implementation issues of an SIC receiver. Moreover, by the nature of SIC, it is easy to extend the implementation to handle more users with an enlarged platform. Our present implementation achieves real‐time speed in the RAKE receiver part of the complete receiver. Due to the complexity in signal regeneration, the overall SIC receiver still falls short of the real‐time requirement when interference cancellation is activated. In fact, the platform employed presently cannot support real‐time processing when the number of multipaths is four or more, unless either the system architecture or the SIC algorithm is redesigned. Such and other ways of improvement are relegated to potential future work. Copyright © 2003 John Wiley & Sons, Ltd.

Modeling the Reliability of Existing Software using Static Analysis (2006)

Software unreliability represents an increasing risk to overall system reliability. As systems become larger and more complex, mission critical and safety critical systems have had increasing functionality controlled exclusively through software. This change, coupled with generally increasing reliability in hardware modules, has resulted in a shift of the root cause of systems failure from hardware to software. Market forces, including decreased time to market, reduced development team sizes, and other factors, have encouraged projects to reuse existing software as well as to purchase COTS software solutions. This has made the usage of the more than 200 existing software reliability models increasingly difficult. Traditional software reliability models require significant testing data to be collected during software development in order to estimate software reliability. If this data is not collected in a disciplined manner or is not made available to software engineers, these modeling techniques can not be applied. It is imperative that practical reliability modeling techniques be developed to address these issues. It is on this premise that an appropriate software reliability model combining static analysis of existing source code modules, limited testing with path capture, and Bayesian belief networks is presented. Static analysis is used to detect faults within the source code which may lead to failure. Code coverage is used to determine which paths within the source code are executed as well as how often they execute. Finally, Bayesian belief network is then used to combine these parameters and estimate the resulting software reliability
Subcutaneous IgG in neurologic diseases (2013)

Subcutaneous administration of IgG (SCIG) has become widely used in primary immune deficiency diseases but it has only recently been studied for maintenance therapy in autoimmune peripheral neuropathies, such as chronic idiopathic demyelinating polyneuropathy and multifocal motor neuropathy. Weekly self-administration of SCIG is safe and well-tolerated, and results in steady-state serum IgG levels, as contrasted with the peaks and troughs of monthly immune globulin (human) for intravenous use. Freedom from the need for venous access or medical personnel for infusions, flexibility in scheduling, convenience of home therapy, and improved clinical stability due to the steady-state IgG levels, lead many patients to prefer SCIG to immune globulin (human) for intravenous use. Long-term studies are needed to determine if the constant IgG levels and clinical stability translate into better long-term outcomes.
