Explaining variations in hospitals’ use of strategic human resource management: How environmental and organizational factors matter (2019)

The study results increase our understanding of variations in hospitals' use of SHRM. Although organizational characteristics were found to explain variations in SHRM, environmental factors seem unrelated with hospitals' use of SHRM. Our results inform both hospital managers and policy makers about possible approaches to enhance SHRM use in hospitals. Furthermore, profound knowledge about factors associated with SHRM will help to enhance our understanding of anticipating changes in hospitals' use of SHRM through organizational- and environmental-oriented interventions.
Improved Optical Resolution of (±)-1,2-Diphenylethylenediamine (1986)

Abstract (±)-1,2-Diphenylethylenediamine (DPEDA) was efficiently resolved by the fractional crystallization of its diastereomeric salts with optically active mandelic acid. 1H-NMR spectrum of N-monoacylated DPEDA with an optically active derivatizing agent showed that DPEDA thus obtained was optically pure.
Development of potential uses for the residue from fluidized bed combustion processes. Quarterly Technical Progress report, December 1979-February 1980 (1980)

The free lime content of the spent bed residue sample from the Georgetown AFB boiler has higher than average free lime, total lime, and magnesium content, and smaller than normal proportion of silica, aluminum, and iron, when compared to previously analyzed spent bed residue samples from other sources. Investigation of the use of spent bed residue as a component of blended cement revealed expansive properties which make such use for conventional concrete construction purposes somewhat questionable. However, these blended cement mixes expand in a predictable manner, show no cracking, and do increase in strength over time, suggesting their application as an expansive concrete for pressure grouting and stowage for mine backfilling. AFB residue/fly ash blends mixed with clay-silt soil exhibit strength development and volume stability characteristics that further recommend the application of such blends as a soil grouting medium. The information and experience obtained in the masonry block demonstration permit an accurate design of mix formulations using AFB residue with conventional block making equipment to meet current ASTM specifications for masonry block. Pre-treatment is necessary in order to develop high-carbon AFB fly ash for use in water treatment applications.
Advancements in Openhole Completion Technology - Establishing and Sustaining Differentiating Sand Control Completion Performance (2011)

Abstract Openhole completions are often selected as the preferred completion technique to maximize reservoir flow potential and provide reliable, high capacity, low skin completions. In many environments, these completions will also require some form of sand control. To meet development objectives, operators are continually challenged to select, design, and install fit-for-purpose completion strategies to optimize ultimate recovery for these fields. These challenges necessitated the creation of new practices, procedures, and hardware to ensure consistent delivery of reliable wellbores, across the entire organization, to achieve long-term, economic success. ExxonMobil embarked on a multi-year initiative to establish and sustain a disciplined, systematic approach to sand control completion design, job execution, and performance assessment. The effort included the development, qualification, and deployment of selective, enabling completion technologies. Additionally, comprehensive engineering and operational guidelines, as well as, in-depth training were delivered to the worldwide engineering and operations workforce. Most significantly, the initiative is now resulting in effective and rapid transfer of learnings and best practices across the global organization. This comprehensive effort continues to focus on ensuring the right people are deploying the right technology in the right well. This paper will discuss the guiding principles associated with our overall completion practices. It will also describe a number of enabling technologies pioneered by ExxonMobil including:• NAFPacSM, a gravel pack technique that allows the operator to run the gravel pack screens in non-aqueous fluid, gravel pack the well and displace the casing to brine, all in one trip• MazeFlo™, a self healing, redundant sand screen• Internal Shunt Alternate Path Technology (ISAPT) screens with openhole shunted packers, a completion technique that enables true and selective zonal isolation in openhole gravel pack applications Introduction Over the last 15 years, our industry has dramatically changed. The contrasts are remarkable. Just 15 years ago:• "Deepwater" was anything over 400 feet, not 4,000 feet• A high volume well made 3,000 bopd, not 30,000 bopd.• Completion intervals were hundreds of feet, not thousands. Unquestionably, the development demands today are far more challenging than ever before. Wells are less accessible, have much higher drilling and completion costs and are more complicated to construct. Since fields are typically being developed with fewer wells, the overall productivity and longevity expectations of each and every completion can far exceed anything experienced in the past. As such, the ability to identify and capture the best completion practices and processes and then apply them systematically is a key step in maximizing resource value
The Role of Macrophage/B-Cell Interactions in the Pathophysiology of B-Cell Lymphomas (2018)

Macrophages (MPs) are heterogeneous, multifunctional, myeloid-derived leukocytes that are part of the innate immune system, playing wide-ranging critical roles in basic biological activities, including maintenance of tissue homeostasis involving clearance of microbial pathogens. Tumor-associated MPs (TAMs) are MPs with defined specific M2 phenotypes now known to play central roles in the pathophysiology of a wide spectrum of malignant neoplasms. Also, TAMs are often intrinsic cellular components of the essential tumor microenvironment (TME). In concert with lymphoid-lineage B and T cells at various developmental stages, TAMs can mediate enhanced tumor progression, often leading to poor clinical prognosis, at least partly through secretion of chemokines, cytokines, and various active proteases shown to stimulate tumor growth, angiogenesis, metastasis, and immunosuppression. Researchers recently showed that TAMs express certain key checkpoint-associated proteins [e.g., programmed cell death protein 1 (PD-1), programmed cell death-ligand 1 (PD-L1)] that appear to be involved in T-cell activation and that these proteins are targets of other specific checkpoint-blocking immunotherapies (anti-PD-1/PD-L1) currently part of new therapeutic paradigms for chemotherapy-resistant neoplasms. Although much is known about the wide spectrum and flexibility of MPs under many normal and neoplastic conditions, relatively little is known about the increasingly important interactions between MPs and B-lymphoid cells, particularly in the TME in patients with aggressive B-cell non-Hodgkin lymphoma (NHL-B). Normal and neoplastic lymphoid and myeloid cell/MP lineages appear to share many primitive cellular characteristics as well as transcriptional factor interactions in human and animal ontogenic studies. Such cells are capable of ectopic transcription factor-induced lineage reprogramming or transdifferentiation from early myeloid/monocytic lineages to later induce B-cell lymphomagenesis in experimental <i>in vivo</i> murine systems. Close cellular interactions between endogenous clonal neoplastic B cells and related aberrant myeloid precursor cells/MPs appear to be important interactive components of aggressive NHL-B that we discuss herein in the larger context of the putative role of B-cell/MP cellular lineage interactions involved in NHL-B pathophysiology during ensuing lymphoma development.
Visual Recognition of American Sign Language Using Hidden Markov Models. (1995)

Hidden Markov models (HMM&apos;s) have been used prominently and successfully in speech recognition and, more recently, in handwriting recognition. Consequently, they seem ideal for visual recognition of complex, structured hand gestures such as are found in sign language. We describe an HMM-based system for recognizing sentence level American Sign Language (ASL) which attains a word accuracy of 99.2% without explicitly modeling the fingers. 1 Introduction There has been a resurging interest in recognizing human hand gestures. While there are many interesting domains, one of the most structured sets of gestures are those belonging to any of the several sign languages. In sign language, each gesture already has assigned meaning, and strong rules of context and grammar may be applied to make recognition tractable. To date, most work on sign language recognition has employed expensive wired &quot;datagloves&quot; which the user must wear [19]. In addition, these systems have mostly concentrated on fin...
<title>Image restoration techniques using Compton backscatter imaging for the detection of buried land mines</title> (1995)

Earlier landmine imaging systems used two collimated detectors to image objects. These systems had difficulty in distinguishing between surface features and buried features. Using a combination of collimated and uncollimated detectors in a Compton backscatter imaging (CBI) system, allows the identification of surface and buried features. Images created from the collimated detectors contain information about the surface and the buried features, while the uncollimated detectors respond (approximately 80%) to features on the surface. The analysis of surface features are performed first, then these features can be removed and the buried features can be identified. Separation of the surface and buried features permits the use of a globbing algorithm to define regions of interest that can then be quantified [area, Y dimension, X dimension, and center location (x<SUB>o</SUB>, y<SUB>o</SUB>)]. Mine composition analysis is also possible because of the properties of the four detector system. Distinguishing between a pothole and a mine, that was previously very difficult, can now be easily accomplished.
Atrial pathology in cardiac amyloidosis: evidence from ECG and cardiovascular magnetic resonance (2006)

A 59-year-old man presented with chest pain and single-vessel coronary disease on angiography. Left ventricular function was normal with mild hypertrophy. He was treated for coronary disease but represented 18 months later with biventricular heart failure. There had been a striking ECG evolution: ST-segment change; reduced QRS amplitude; increased P-wave width and amplitude; and progressive increase in PR interval (196–276 ms) (Panel A). Echocardiography now …
Limits to program testing with random number inputs (2005)

The principal feature of this paper is the illustration of a method which may be useful in the estimation of the number of execution sequences (i.e., realizable logical paths) of a given program. This is accomplished through use of event-altered rate models, particularly the Jelinski-Moranda purification process. A sequence of random numbers is used as input data or drivers for the program, and, on the basis of the spacings between the occurrences of "new" execution sequences, the total number which can be driven by such numbers can be estimated. An application to a particular program is described.
Monitoring and control of industrial power systems (1989)

The authors discuss systems designed specifically for industrial customers of electric utilities, which provide functions similar to those of electronic monitoring and control systems used by utilities but are tailored to meet the specific requirements of an industrial power system. They describe the system architecture of such systems and some of its features and examine the benefits obtained from their use.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

All-optical 87Rb Bose-Einstein condensate apparatus: construction and operation (2012)

Research on degenerate quantum gases of dilute atomic gases has become a well established field in modern physics and revealed many astonishing phenomena. The first experiments on Bose and Fermi gases at low temperatures aimed to prove the predictions of quantum mechanics on a macroscopic scale. Since then we make use of Bose and Fermi gases and mixtures of any combination to model other many body systems. A property of Bose Einstein condensates is superfluidity which we want to investigate further in toroidal potentials with a new apparatus which can produce an all-optical BEC. This means trapping thermal atoms in an optical dipole trap and cooling the sample by evaporation into the quantum degenerate regime. This new technique was first successfully demonstrated by M.D. Barrett et al. in 2001 and promises to be faster and simpler than the well established and common way of evaporation in magnetic traps. A new apparatus was built by the author and we report on the experimental details of the trapping of 87Rb atoms from a hot vapour and cooling them in a magneto-optical trap, and further evaporation to quantum degeneracy in a crossed optical dipole trap operating at a wavelength of l = 1064nm, with accurate control of the power in both beams via a feedback loop. The evaporation of neutral atoms of 87Rb in far red detuned optical dipole traps using linearly polarised laser light is spin independent, and mixed spinor condensates of the F=1 manifold can be formed. As an empirical technique we found by applying a magnetic gradient field during the final evaporation that we can selectively populate mF spin states or prepare mixtures. This intriguing mechanism was found earlier as well by M. S. Chang, but is yet not fully understood and subject of our future research. We can now routinely prepare an almost pure condensate containing up to 7000 atoms in the condensed phase purely in the mF = 0 spin state. This thesis contains the theoretical framework of Bose-Einstein condensation with in mean-field theory, the concepts of cooling of atoms in magneto-optical traps, the trapping and evaporation in optical dipole traps and the experimental realisation. In the future this experiment will be extended by a fast scanning dipole trap to apply arbitrary time averaged potentials of more complex geometries, such as toroidal traps to study the effects of superfluidity in a periodic potential. The production of toroidal traps and cold atoms in such a trap are outlined in this thesis.
<i>Pneumocystis</i>Workshop: 10th Anniversary Summary (2009)

The presentations on Pneumocystis discussed here represent 10 international meetings that span over 20 years of research. These workshops were initiated by a nascent community of researchers investigating a poorly understood organism, Pneumocystis, which at that time was gaining prominence because of its importance to immunosuppressed patients, especially those infected with human immunodeficiency virus (HIV). Pneumocystis defied phylogenetic classification, which at the time was based primarily on morphological characteristics. Because of this uncertainty, Pneumocystis lay outside the mainstream research of both mycology and parasitology and did not have a forum for this new group of investigators. The first “Workshop on Pneumocystis carinii” filled that gap in 1988, and subsequent workshops were platforms for the cutting-edge science that was performed in this microbial arena. The first reports of its identity as a member of the fungal kingdom were presented in the workshop series, and discussions of importance to the community were held under its auspices, such as the initiation of the genome project and nomenclatural changes. The 10th workshop, conducted in 2008, continued this tradition, and the scientific achievements of the community are summarized here.
BSES's PEC Unit up and running (2012)

Earlier this year, in readiness for sugar research and development (R and D) reform, the Professional Extension and Communication (PEC) Unit within BSES Limited was formed. The PEC Unit plays a critical role in disseminating the results of collaborative R and D, and highlighting tangible scientific outcomes to fuel the growth of the Australian sugar industry.
Changes in specific cleavability of the Sendai virus fusion protein: implications for pathogenicity in mice (1992)

Sendai virus mutants, KDe-21 and KDe-62, which had undergone multiple cycles of replication in Madin Darby canine kidney (MDCK) cells in the absence of exogenous proteases were isolated. The fusion (F) protein of the mutants regained proteolytic cleavability in MDCK cells and chick embryos, but the F protein remained non-cleavable in other cell lines. Unlike the F protein of wild-type (wt) virus, the mutant F was resistant to trypsin but was sensitive to elastase and, to a lesser extent, to chymotrypsin. Sequence analyses of the F gene and the F protein revealed an amino acid substitution at the cleavage site, Arg(116) to Ile, which conferred trypsin resistance and enhanced cleavability at Ile(116) by elastase and host proteases present in MDCK cells and in chicken embryos. In contrast to the pneumopathogenicity in mice of wt Sendai virus, the KDe mutants were non-pathogenic; cleavage activation of the F protein did not occur in the lungs and thereby infection was terminated after an initial cycle of replication.
MRIW: parametric analysis software for contrast-enhanced dynamic MR imaging in cancer. (1998)

A software package called the Magnetic Resonance Imaging Workbench has been developed to characterize contrast agent uptake in vivo following T1-weighted magnetic resonance (MR) imaging with qualitative analysis of changes in signal intensity or quantitative analysis of changes in contrast agent concentration over time. Various descriptors may be calculated from the analysis of dynamic contrast agent-enhanced MR studies and visualized as false-color overlays, which allow the immediate display and interpretation of information taken from a series of images acquired over time. Qualitative descriptors include onset of enhancement, initial gradient, mean gradient, maximum enhancement, and washout. These parameters can be particularly useful in the investigation of multifocal or widespread disease. Quantitative descriptors include capillary permeability-surface area product, extracellular volume, and T1 and may be used to monitor changes in the disease state and to assess the efficacy of treatment. In addition, they allow comparison of data obtained from different patients, from independent MR studies, or from studies performed with different modalities. Analysis of contrast enhancement during MR imaging in terms of such qualitative or quantitative parameters is a promising new method of data analysis in radiology.
Segmentation of Subtraction Images for the Measurement of Lesion Change in Multiple Sclerosis (2008)

SSEG unveiled a relationship between T2 LVC and concomitant brain atrophy and demonstrated significantly higher measurement reproducibility. SSEG, a promising tool providing detailed analysis of subtle alterations in lesion size and intensity, may provide critical outcome measures for clinical trials of novel treatments, and may provide further insight into progression patterns in MS.
Antigenic heterogeneity of breast cell lines detected by monoclonal antibodies and its relationship with the cell cycle (1985)

Established cell lines were stained by immunofluorescence with four monoclonal antibodies to study the phenomenon of antigenic heterogeneity and its possible relation to the cell cycle. Five cell lines thought to be of breast origin, MCF-7, ZR-75-1, T47D, MDA-MB-231 and HBL-100, were stained with three monoclonal antibodies (LICR-LON-M8, LICR-LON-M18, LICR-LON-M24) that each stain a distinct subset of normal breast epithelial cells, i.e. demonstrate antigenic heterogeneity in normal breast epithelial cells. Contrasting monoclonal antibodies LICR-LON-FIB75 and LICR-LON-FIB86 to homogeneously expressed antigens were also used. For the antibodies demonstrating heterogeneity distinct positive and negative fractions were not seen by flow cytometry; the intensity of fluorescence varied continuously from background to a hundred times stronger than background. Fluorescent DNA staining showed no obvious relation between antigen expression and the cell cycle. The essentially constant proportion of cells of a given antigenic phenotype in the various phases suggests that these antibodies do not distinguish a phenotype associated with a distinct proliferating population of cells.
Lossless watermarking for image authentication: a new framework and an implementation (2006)

We present a novel framework for lossless (invertible) authentication watermarking, which enables zero-distortion reconstruction of the un-watermarked images upon verification. As opposed to earlier lossless authentication methods that required reconstruction of the original image prior to validation, the new framework allows validation of the watermarked images before recovery of the original image. This reduces computational requirements in situations when either the verification step fails or the zero-distortion reconstruction is not needed. For verified images, integrity of the reconstructed image is ensured by the uniqueness of the reconstruction procedure. The framework also enables public(-key) authentication without granting access to the perfect original and allows for efficient tamper localization. Effectiveness of the framework is demonstrated by implementing the framework using hierarchical image authentication along with lossless generalized-least significant bit data embedding.
Face Tracking by Means of Continuous Detection (2004)

The main contribution of this work is a new view to face-tracking namely to associate the independent detection results obtained by applying a real-time detector to each frame of a sequence. This differs fundamentally from traditional tracking which is mostly understood as finding the location of a target object given its previous position and a correspondence finding algorithm either with or without a prior object model. This traditional notion has two major problems namely the initialization problem and the lost-track problem. We show that the advent of new rapid detection algorithms may change the need for traditional tracking. Furthermore the mentioned problems have a natural solution within the presented tracking by continuous detection approach. The only assumption on the object to track is it's maximal speed in the image plane, which can be set very generously. From this assumption we derive three conditions for a valid state sequence in time. To estimate the optimal state of a tracked face from the detection results a Kalman filter is used. This leads to an instant smoothing of the face trajectory. It can be shown experimentally that smoothing the face trajectories leads to a significant reduction of false detections compared to the static detector without the presented tracking extension. We further show how to exploit the highly redundant information in a natural video sequence to speed-up the execution of the static detector by a temporal scanning procedure which we call "slicing".
