Whole Blood Tissue Factor Procoagulant Activity Is Elevated in Patients With Sickle Cell Disease (1998)

We developed a simple assay for the measurement of tissue factor procoagulant activity (TF PCA) in whole blood samples that avoids the need for mononuclear cell isolation. This method combines convenience of sample collection and processing with a high degree of sensitivity and specificity for TF. Using this method, we have determined that TF PCA is detectable in whole blood samples from normal individuals, which is itself a novel observation. Essentially all PCA could be shown to be localized in the mononuclear cell fraction of blood. Compared with controls, whole blood TF levels were significantly (P < .000001) elevated in patients with sickle cell disease (SCD), regardless of the subtype of hemoglobinopathy (SS or SC disease). No significant difference in TF PCA was observed between patients in pain crisis compared with those in steady-state disease. Because TF functions as cofactor in the proteolytic conversion of FVII to FVIIa in vitro, it was expected that an increase in circulating TF PCA would lead to an increased in vivo generation of FVIIa. On the contrary, FVIIa levels were actually decreased in the plasma of patients with SCD. Plasma TF pathway inhibitor (TFPI) antigen levels were normal in SCD patients, suggesting that accelerated clearance of FVIIa by the TFPI pathway was not responsible for the reduced FVIIa levels. We propose that elevated levels of circulating TF PCA may play an important role in triggering the activation of coagulation known to occur in patients with SCD. Because TF is the principal cellular ligand for FVIIa, it is possible that increased binding to TF accounts for the diminished plasma FVIIa levels.
Continuous heating transformation (CHT) cure diagram of an aromatic amine/epoxy system at constant heating rates (1991)

Abstract The overall reaction kinetics of a high‐ T g tetrafunctional aromatic diamine/difunctional epoxy system (maximum glass transition temperature, T g ∞ = 182°C), which can satisfactorily describe the rate of the reaction in both kinetically and diffusion‐controlled regimes, had been determined earlier from isothermal conversion/ T g data by differential scanning calorimetry (DSC). The mathematical expression of the kinetics, together with the unique one‐to‐one relationship between T g and chemical conversion, is used to calculate the material's T g vs. time under heating at constant rates. For a heating scan from below T g 0 (the glass transition temperature of the unreacted material), initial devitrification corresponds to the reaction temperature ( T cure ) first passing through the T g of the reacting material; vitrification corresponds to T g becoming equal to the increasing T cure after initial devitrification; and finally, upper devitrification corresponds to T g eventually falling below the rising T cure . The results of the calculation correlate well with the available experimental data of the dynamic mechanical behavior of the material during temperature scans at constant rates that were obtained by the torsional braid analysis (TBA) technique. T g is calculated to remain slightly higher than T cure after vitrification due to the influence of diffusion control, the difference being greater for lower heating rates. The limiting heating rate with no initial devitrification and that with no vitrification are also calculated.
Porosity and Pore Size Regulate the Degradation Product Profile of Polylactide (2011)

Porosity and pore size regulated the degradation rate and the release of low molar mass degradation products from porous polylactide (PLA) scaffolds. PLA scaffolds with porosities above 90% and different pore size ranges were subjected to hydrolytic degradation and compared to their solid analog. The solid film degraded fastest and the degradation rate of the porous structures decreased with decreasing pore size. Degradation products were detected earlier from the solid films compared to the porous structures as a result of the additional migration path within the porous structures. An intermediate degradation rate profile was observed when the pore size range was broadened. The morphology of the scaffolds changed during hydrolysis where the larger pore size scaffolds showed sharp pore edges and cavities on the scaffold surface. In the scaffolds with smaller pores, the pore size decreased during degradation and a solid surface was formed on the top of the scaffold. Porosity and pore size, thus, influenced the degradation and the release of degradation products that should be taken into consideration when designing porous scaffolds for tissue engineering.
The Rainbow Workstation (1984)

An experimental workstation is described that supports high-quality colour raster graphics in a distributed environment. Hardware assistance for screen management is provided, using a method that allows rapid reconfiguration of screen images. Much of the workstation function is defined by high-level software and loadable microcode, thus permitting the exploration of different ways of using this kind of equipment.

Anatomical variation of pulmonary venous ostium and its relationship with atrial arrhythmia in the Saudi population (2013)

The association between anatomically varied venous ostia and atrial arrhythmia was significant (p = 0.000) with a significantly higher anatomical variation of pulmonary venous ostia in the female Saudi population (p = 0.034).
ITM Oxygen for Gasification (2005)

Abstract An Air Products-led team is developing a new air separation technology - Ion Transport Membrane Oxygen - based on ceramic membranes that selectively transport oxygen ions when operated at high temperature. Under the influence of an oxygen partial-pressure driving force, the ITM Oxygen process achieves a high-purity, high-flux separation of oxygen from air. By integrating the energy-rich, vitiated, non-permeate stream with a gas turbine system, the overall process co-produces high-purity oxygen, power, and steam if desired. As a result, the technology is ideally suited for advanced energy conversion processes such as IGCC that require oxygen and use heavy carbonaceous feedstocks (resid oils, bitumens, coke, coal), as well as for traditional industrial applications for oxygen and distributed power. During Phases I and II of a three-phase development program with the U.S. Department of Energy, the ITM Oxygen team established the feasibility of the ceramic membrane approach and designed and built commercial-scale membrane modules. A prototype facility that will produce 5 tons-per-day of oxygen will start up this year. Larger-scale test rigs are planned, with commercialization projected in the latter part of the decade. This paper will present an overview and status of the ITM Oxygen development effort, and the integration into gasification and clean energy processes. Process integration options will be discussed and contrasted. The economic benefits compared to the best commercial air separation alternative will be highlighted.
Coreless substrates status (2010)

Coreless organic substrates have been desired for many years in order to provide the ultimate wiring capacity that can be achieved anywhere. To date, there have been few successful implementations only for small body sizes because of the choice of dielectric materials. Here, a technology has been developed based on prepreg dielectrics and pattern plating to build sequentially the layers of a coreless substrate. A temporary carrier is employed to facilitate handling during the manufacturing process.

Near Infrared Fluorescence-Based Bacteriophage Particles for Ratiometric pH Imaging (2008)

Fluorogenic imaging agents emitting in the near-infrared are becoming important research tools for disease investigation in vivo. Often pathophysiological states such as cancer and cystic fibrosis are associated with disruptions in acid/base homeostasis. The development of optical sensors for pH imaging would facilitate the investigation of these diseased conditions. In this report, the design and synthesis of a ratiometric near-infrared emitting probe for pH quantification is detailed. The pH-responsive probe is prepared by covalent attachment of pH-sensitive and pH-insensitive fluorophores to a bacteriophage particle scaffold. The pH-responsive cyanine dye, HCyC-646, used to construct the probe, has a fluorogenic pKa of 6.2, which is optimized for visualization of acidic pH often associated with tumor hypoxia and other diseased states. Incorporation of pH-insensitive reference dyes enables the ratiometric determination of pH independent of the probe concentration. With the pH-responsive construct, measurement of intracellular pH and accurate determination of pH through optically diffuse biological tissue is demonstrated.
Studying and Implementation of Embedded System's Code Replacement Technique (2008)

A code replacement technique and tool were proposed in this paper, which can be used in embedded systems to fulfill the needs, module updating and debugging and defects modifying and otherwise, and promised that never disturb the system's routine running. The technique could be used in critical application areas for module updating and debugging, also some special areas which had some other requirement when updating and debugging. Through the argumentation and development of prototype, some conclusions could be drew safely: the first, meeting the requirement associated with the real-time response and having none or little bad impact to the system; the second,the complicated and resource-consumed operations were placed at host, so the technique didn't depend the target machine's capability much and could be used for almost all the embedded systems which had more or less resource and processing capability.
Effect of Piper longum Linn, Zingiber officianalis Linn and Ferula species on gastric ulceration and secretion in rats. (2000)

Use of Dipaniya Mahakasaya, a group consisting of 10 herbal drugs, has been suggested in Charaka Samhita to improve digestion. Out of these 10 plants, three, viz. P. longum (water decoction), Z. officianalis (water decoction) and Ferula species (colloidal solution) were studied for their antiulcer and mechanism of antiulcer effects in rats. All the drugs in the dose of 50 mg/kg, p.o., 60 min prior to experiment, showed significant protection against gastric ulcers induced by 2 hr cold restraint stress, aspirin (200 mg/kg, 4 hr) and 4 hr pylorus ligation. The antiulcerogenic effect seemed to be due to the augmentation of mucin secretion and decreased cell shedding rather than offensive acid and pepsin secretion which however, were found to be increased by them.
TaPS widgets (2011)

Interacting with private data is important in multi-user table-top systems, but hard to implement with current technology. Existing approaches usually involve wearable devices such as shutter glasses or head-mounted displays that are cumbersome to wear. We present TaPS, lightweight transparent widgets that only pass light coming from a particular direction to shield the content beneath them from other users, creating Tangible Private Spaces. TaPS widgets use low-cost hardware to provide tangible privacy controls to interactive tabletops. Informal studies indicate that TaPS widgets enable users to successfully move documents between public and private tabletop spaces without compromising privacy and allow for secret data entry.

Personality Types and Total Enterprise Simulation Performance (1991)

Patz. (1990) presented evidence that total enterprise simulations are biased in favor of particular personality types. While the results of this study disagree with Pat/s conclusion as to the particular personality that will perform best on a simulation, support was found for the position that a relationship does exist between personality and performance. The current study used individuals as simulation company managers to eliminate the problems of group effects existing in Patzâ€™s group-managed companies.
Critically Timed Auxiliary Shock to Weak Field Area Lowers Defibrillation Threshold (2001)

Application of a small auxiliary shock, just before or simultaneously with a primary shock, to the cardiac region where the primary shock field is weakest significantly lowers DFT.
Prediction of ^|^sigma; Phase Precipitation in Type 316FR Stainless Steel Weld Metal (2013)

Through the isothermal ageing treatments at 873, 923, 973, and 1023K, precipitation of sigma (σ) phase in type 316FR stainless steel weld metal was examined based on the kinetics approach. Microstructural examination was performed by scanning electron microscopy (SEM), electron backscatter diffraction (EBSD) and transmission electron microscopy (TEM). The dominantly precipitated phases were sigma (σ) and chi (χ), nucleated at δ-ferrite/austenite (γ) interface or interior of the δ-ferrite grains, consuming the δ-ferrite during isothermal holding at each of ageing temperature. The total amount of intermetallic phases precipitated during isothermal ageing sigmoidally increased as a function of the ageing time. Precipitation of these intermetallic phases could be approximately followed by Johnson-Mehl equation. Based on the determined kinetic equation, precipitation behavior of intermetallic phases at service-exposure temperature could be successfully predicted.
Optimal Coarsening of 3D Reservoir Models for Flow Simulation (2006)

Summary We have developed a new constrained optimization approach to the coarsening of 3D reservoir models for flow simulation. The optimization maximally preserves a statistical measure of the heterogeneity of a fine-scale model. Constraints arise from the reservoir fluids, well locations, pay/nonpay juxtaposition, and large-scale reservoir structure and stratigraphy. The approach has been validated for a number of oil and gas projects, where flow simulation through the coarsened model is shown to provide an excellent approximation to high-resolution calculations performed in the original model. The optimal layer coarsening is related to the analyses of Li and Beckner (2000), Li et al. (1995), and Testerman (1962). It differs by using a more accurate measure of reservoir heterogeneity and by being based on recursive sequential coarsening instead of sequential refinement. Recursive coarsening is shown to be significantly faster than refinement: the cost of the calculation scales as (NX·NY·NZ) instead of (NX·NY·NZ)2. The more accurate measure of reservoir heterogeneity is very important; it provides a more conservative estimate of the optimal number of layers than the analysis of Li et al. The latter is shown to be too aggressive and does not preserve important aspects of the reservoir heterogeneity. Our approach also differs from the global methods of Stern and Dawson (1999) and Durlofsky et al. (1996). It does not require the calculation of a global pressure solution, nor does it require the imposition of large-scale flow fields, which may bias the analysis (Fincham et al. 2004). Instead, global flow calculations are retained only to validate the reservoir coarsening. Our approach can also be used to generate highly unstructured, variable-resolution computational grids. The layering scheme for these grids follows from the statistical analysis of the reservoir heterogeneity. Locally variable resolution follows from the constraints (reservoir structure, faults, well locations, fluids, pay/ nonpay juxtaposition). Our reservoir simulator has been modified to allow a fine-scale model to be initialized and further coarsened at run time. This has many advantages in that it provides both simplified and powerful workflows, which allow engineers and geoscientists to work with identical shared models.
Perforating System Selection for Optimum Well Inflow Performance (2002)

Abstract Oilfield operators and service companies continually face challenges to provide completions that not only produce at optimum levels but also accelerate return on investment (ROI). These operational demands are further complicated by the fact that the range of reservoir scenarios continues to expand. In attempting to satisfy these needs, one component of the completion process is often over looked or taken for granted — the perforation process. In the energy industry, many companies base their selection of shaped-charge perforators solely on API Section I criteria such as depth of penetration or casing-exit hole size. Other factors, such as the actual performance of given shaped charges at in situ conditions, also should be evaluated when making perforating decisions for the completion process. Focusing perforator system performance on reservoir productivity rather than on the shaped-charge performance optimized for concrete testing (which is the case with API Section I) can ultimately lead to significant improvement in well inflow performance. Although API RP43 Section IV perforating procedures (to evaluate well perforators under in-situ conditions) have existed since 1985, there has been limited field validation of experimental results and model predictions based on these procedures.1-3 This paper discusses insights gained from a series of Section IV tests conducted with Berea and Castlegate sandstone cores under varying in situ conditions. The Section IV lab experiments represent physical models of the near-wellbore region during perforation and completion processes under in-situ stress. The results of these experiments indicate that understanding the inherent system inadequacies and experimental conditions is critical to proper integration of the results with theoretical models and field data.
A wearable neural interface for detecting and decoding attempted hand movements in a person with tetraplegia (2019)

We are developing a wearable neural interface based on high-density surface electromyography (HDEMG) for detecting and decoding signals from spared motor units in the forearms of people with tetraplegia after spinal cord injury (SCI). A lightweight, form-fitting garment containing 150 disc electrodes and covering the entire forearm was used to map the myoelectric activity of forearm muscles during a wide range of voluntary tasks of a person with chronic tetraplegia after SCI (C5 motor and C6 sensory American Spinal Injury Association Impairment Scale B spinal cord injury). Despite exhibiting no overt finger motion, myoelectric signals were detectable for attempted movements of individual digits and were highly discriminable. Motor unit decomposition was used to identify the activity of >30 motor neurons, active specifically during rotation, pronation of the wrist (4 units), and flexion of the elbow joint (7 units), and during attempted movements of individual hand digits (1-5 units). In addition, we performed a neural connectivity analysis based on the power of the common oscillations of the identified motor neurons in the delta (~5Hz), alpha (~6-12 Hz), and beta bands (~15-30 Hz). This analysis showed clear common synaptic inputs to the identified motor neurons in all the analyzed frequency bands. This neural interface offers a new potential for the control of assistive technologies, whereby the motor neurons spared after SCI may serve as a direct readout of motor intent that allows proportional control over several distinct degrees of freedom. Moreover, this framework can be used to study the reorganization and recovery of spinal networks after injury and rehabilitation.
Machine annotation of sets of traditional Irish dance tunes (2021)

A set in traditional Irish music is a sequence of two or more dance tunes in the same time signature, where each tune is repeated an arbitrary number of times. A turn in a set represents the point at which either a tune repeats or a new tune is introduced. Tunes in sets are played in a segue (without a pause) and so detecting the turn is a significant challenge. This paper presents the MATS algorithm, a novel algorithm for identifying turns in sets of traditional Irish music. MATS works on digitised audio files of monophonic flute and tin-whistle music. Previous work on machine annotation of traditional music is summarised and experimental results validating the MATS algorithm are presented.
