In situ Determination of Fuel Particle Reaction Rates by Simultaneous Measurement of Particle Temperature and Size (2000)

The most widespread example of gas-solids reactions in practice is the combustion of solid fossil fuels for power and/or heat production. Efficiency enhancement, e.g., by combined gas and steam turbine processes with pressurized combustion, has been the subject of research and development worldwide. In the present work, the combustion behavior of char particles under conditions of high temperature and pressure is investigated by means of in situ determination of the reaction rates.
Nonionic photoacid generator behavior under high-energy exposure sources (2009)

A series of nonionic photoacid generators (PAGs) are synthesized and their acid generation efficiency measured under deep ultraviolet (DUV) and electron beam exposures. The acid generation efficiency is determined with an on-wafer method that uses spectroscopic ellipsometry to measure the absorbance of an acid sensitive dye (Coumarin 6). Under DUV exposures, common ionic onium salt PAGs show excellent photoacid generation efficiency, superior to most nonionic PAGs tested in this work. In contrast, when under 100-keV high energy e-beam exposures, almost all of the nonionic PAGs show significantly better acid generation performance than the ionic onium salt PAGs tested. In particular, one nonionic PAG shows almost an order of magnitude improvement in the Dill C acid generation rate constant compared to a triarylsulfonium PAG. The high energy acid generation efficiency is found to correlate well with the electron affinity of the PAGs, suggesting that improvements in PAG design can be predicted. Nonionic PAGs merit further investigation as a means for producing higher sensitivity resists under high energy exposure sources.
Unraveling Hidden Order in the Dynamics of Developed and Emerging Markets (2014)

The characterization of asset price returns is an important subject in modern finance. Traditionally, the dynamics of stock returns are assumed to lack any temporal order. Here we present an analysis of the autocovariance of stock market indices and unravel temporal order in several major stock markets. We also demonstrate a fundamental difference between developed and emerging markets in the past decade - emerging markets are marked by positive order in contrast to developed markets whose dynamics are marked by weakly negative order. In addition, the reaction to financial crises was found to be reversed among developed and emerging markets, presenting large positive/negative autocovariance spikes following the onset of these crises. Notably, the Chinese market shows neutral or no order while being regarded as an emerging market. These findings show that despite the coupling between international markets and global trading, major differences exist between different markets, and demonstrate that the autocovariance of markets is correlated with their stability, as well as with their state of development.
Face recognition with pose and illumination variations using new SVRDM support-vector machine (2004)

Face recognition with both pose and illumination variations is considered. In addition, we consider the ability of the classifier to reject nonmember or imposter face inputs; most prior work has not addressed this. A new SVRDM (support-vector representation and discrimination machine) classifier is proposed, and initial face recognition-rejection results are presented.
Tribo-Chemical Modeling of Copper CMP (2006)

We are developing an integrated tribo-chemical model of copper CMP that considers abrasive and pad properties, process parameters (speed, pressure etc.), and slurry chemistry to predict material removal rates. In this paper, the framework of the model is explained, and two important constituents of the model are presented: transient passivation behavior and characteristics of mechanical interactions.

The Effect of the Drop Size on the Print Quality in CIJ Printing (1999)

Only scant attention has been paid in the literature to the influence of the drop size on the dynamics of spreading and the final dot quality with different paper grades. In this study, the development of the image properties was observed on a time scale of a few milliseconds and upward, by using a special high-speed imaging environment (introduced at NIP13) and CIJ printers, with different nozzle sizes but similar water-based ink compositions.The results clearly show that there is a strong paper-dependent affiliation between the size of the ink jet drop and the high-speed dynamic phenomenon of dot spreading and drying. With coated paper grades, the interrelation between the drop size and the magnitude of the surface structure was found to be important, compared with the final shape of the dot. With uncoated papers, the growth of the dot is dependent on the size of the drop. The final intensity of the print was found to be the outcome of the characteristics of the ink and the absorption properties of the paper.
Effects of Altitude, Acidosis, and Alkalosis upon Hypoxic Threshold. (1955)

1. Inspired oxygen tensions which produce the first discernible increases in ventilation (hypoxic thresholds) were measured in subjects acclimatized to Mt. Evans, Colo. (14,150 feet) and to Denver, Colo. (5300 feet). In addition thresholds were measured in subjects living in Denver who were in chronic metabolic acidosis (NH4CI) and in chronic metabolic alkalosis (NaHCO3). 2. Mt. Evans subjects showed an average threshold of 179 mm tracheal PO2 and those at Denver 127 mm. Reports in the literature pinpoint the threshold for sea level dwellers at about 93 mm. Furthermore the threshold for Denverites ingesting NH4CI was 163 mm and for those ingesting NaHCO3 was 107 mm. 3. Since NH4CI changed PAO2 and pH in the opposite direction from altitude but changed the hypoxic threshold in the same direction, these agents were ruled out as threshold governors. It was suggested that probably the hypoxic threshold is a function of either the resting PCO2 or the bicarbonate level to which the individual had acclimatized.

<title>Progress toward making lightweight 8-m mirrors of short focal length</title> (1990)

A technique has been developed for casting glass in the form of a honeycomb structure possessing good stiffness despite its low weight, and facilitating thermal control via forced ventilation of the honeycomb cells. To date, 3.5 m diameter mirrors of this type have been successfully cast; fully 8 m diameter mirrors are expected to be cast by 1992. No mirror of diameter as large as 8 m has ever been polished, however, and the difficulties which will be encountered shall be compounded by the shorter focal lengths required for advanced telescopic optics. A novel method, designated 'stressed lap polishing', has been developed to address these problems.

CorT Total generated with the Scheimpflug device corresponded better with the manifest refractive cylinder than all measures of total corneal astigmatism calculated by the software from both the Scheimpflug and the dual Scheimpflug/Placido devices.
Clincal experience with an ECM scaffold for tissue engineering (2003)

Summary form only given. Porcine-derived, xenogeneic extracellular matrix (ECM) has been used as a scaffold for several tissue engineering applications in more than 100,000 human patients during the past two years. This xenogeneic ECM is derived from the small intestinal submucosa (SIS) of pigs. This ECM has been shown to contain numerous growth factors including vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), transforming growth factor beta (TGF beta), and a naturally occurring mixture of glycosaminoglycans, proteoglycans, and several types of structural collagen. These functional and structural proteins are arranged in a unique ultrastructure that supports constructive tissue remodeling. Clinical applications in humans have included repair of chronic, full-thickness skin wounds, lower urinary tract reconstruction, gastrointestinal tract repair, replacement of the dura mater, repair and replacement of numerous musculoskeletal soft tissue structures including the rotator cuff, Achilles tendon, and ligamentous structures, and arterial vascular repair, among others. Common features of ECM remodeling include rapid and complete scaffold degradation (within 2-3 months) and population of the scaffold by host-derived, site appropriate mesenchymal and epithelial cells. A review of the clinical experience, including the immunologic response of the patients to this xenogeneic scaffold, will be presented.
Jastrow correlation factor for periodic systems (2016)

We propose a Jastrow factor for electron-electron correlations that interpolates between the radial symmetry of the Coulomb interaction at short interparticle distance and the space-group symmetry of the simulation cell at large separation. The proposed Jastrow factor captures comparable levels of the correlation energy to current formalisms, is 40% quicker to evaluate, and offers benefits in ease of use, as we demonstrate in quantum Monte Carlo simulations.

Learning-based joint power and channel assignment for hyper dense 5G networks (2016)

Next generation mobile networks will face the unprecedented demand for higher data rates. To satisfy this demand, the dense deployment of heterogeneous wireless networks (HetNets) is a promising solution. One of the major challenges in dense HetNets is to dynamically allocate the resources such as power and channel so that the energy efficiency and throughput of the network improve. One of the important techniques for improving the energy efficiency of the base station (BS) is BS ON-OFF switching which allows the BS to turn off some of its components in lower load situations. On the other side, due to the proximity of BSs in the dense HetNets, co-channel interference (CCI) becomes a critical problem and significantly impacts the performance of the network. In this paper, we propose a dynamic channel assignment based on a learning algorithm (DCA-LA). Moreover, we combine DCA-LA with a BS ON-OFF switching algorithm in order to improve the energy efficiency of the system. In particular, the proposed DCA-LA/ON-OFF switching algorithm is self-organizing and performs in a fully distributed manner. Simulation results indicate that our proposed algorithm balances load among BSs and yields better performance in terms of average energy consumption, average load, average utility per BS and average rate per user, compared to the baseline algorithms.
Vadose‐Zone Techniques for Estimating Groundwater Recharge in Arid and Semiarid Regions (1994)

Abstract Both physical and chemical methods have been used to estimate recharge in arid and semiarid areas. Our review indicates that indirect, physical approaches, such as water balance and Darcy flux measurements, are the least successful, while methods using tracers (e.g., Cl, 3 H, and 36 Cl) have been the most successful in estimating ground‐water recharge in dry regions. Lysimeters, which can directly measure root‐zone drainage, have been useful in quantifying recharge, particularly for coarse soils, but are costly to construct and operate. Of the tracer techniques available, Cl balance techniques appear to be the simplest, least expensive, and most universal for recharge estimation. In Australian studies, under native vegetation in semiarid areas, Cl profiles were found to be remarkably uniform, indicating very low and relatively uniform rates of groundwater recharge. Following changes in land use, recharge appeared to become much more variable, increasing more than two orders of magnitude. Methods for scaling point estimates of recharge to large areas using indirect techniques (such as nondestructive electromagnetic induction) have also been developed. In deep unsaturated zones, the pressure response in the soil water may be recorded in the profile, and simple field measurements may be used to obtain semi‐independent verification of recharge rates determined by using Cl balance techniques.
α-weighted cumulant projections: a novel tool for system identification (2002)

We propose a new tool, the /spl alpha/-weighted cumulant projection (/spl alpha/-WCP), which is an one-dimensional projection of the exponentially weighted n/sup th/ order cumulants of a process. We show that a real, stable and generally nonminimum phase LTI system can be identified from a single projection, whereas a complex system requires two projections corresponding to two different values of the weight /spl alpha/. We develop two methods for system identification, one based on the complex cepstrum of /spl alpha/-WCP and the other based on the Fourier-phase of /spl alpha/-WCP. The proposed methods exhibit comparable statistical performance and substantially lower computational complexity compared to existing higher-order spectra based techniques.
Association of ABCC10 polymorphisms with nevirapine plasma concentrations in the German Competence Network for HIV/AIDS (2011)

Nevirapine is a substrate for ABCC10 and genetic variants influence its plasma concentrations. ABCC10 in lymphocytes and macrophages may also contribute to variability in intracellular permeation of nevirapine. Further studies are required to determine the clinical implications of these findings.
Carcinogenetic mechanisms of endocrine disruptors in female cancers (Review) (2016)

Endocrine disruptors (EDs) are pollutants that alter the endocrine system and are involved in carcinogenesis. EDs have multiple and complex levels of action. They can affect the synthesis, release and transport of natural hormones. In target tissues, EDs can reduce or increase the effects of natural hormones on their receptors and change signaling cascades. When ED exposure happens at critical periods of life, from embryo to puberty, they can act at doses considered safe for an adult. Furthermore, their epigenetic effects can also influence the cancer risk of future generations. The cancer mechanisms of known EDs are hereby reviewed, There are thousands of newly introduced substances whose potential endocrine-disrupting and cancer effects are completely unknown. Although there are still gaps in our knowledge, these data support the urgent need for health and environmental policies aimed at protecting the public and in particular, the developing fetus and women of reproductive age.
Conformation, Filament Assembly, and Activity of Single-Headed Smooth Muscle Myosin (1998)

Single-headed myosin was prepared by digestion of porcine aorta smooth muscle myosin with Staphylococcus aureus V8 protease in the presence of actin. The single-headed myosin preparation contained intact light chains, a rod fragment of a heavy chain, and a heavy chain of which only a minor fraction contained a nick in the head segment. Below 0.2 M NaCl, the single-headed myosin showed a decrease in Ca2+-ATPase activity and an increase in the elution time on gel filtration HPLC in a phosphorylation-dependent manner, indicating a phosphorylation-dependent conformational transition between the extended and folded forms. These conformations were confirmed by electron microscopic observation of rotary-shadowed samples of single-headed myosin. However, the conformational transition of single-headed myosin occurred in a narrower range with lower salt concentrations than that of double-headed myosin. The filament assembly of single-headed myosin was thus facilitated and phosphorylation-independent. The single-headed myosin also showed high actin-activated ATPase activity independent of phosphorylation. These results indicate that the two-headed structure of smooth muscle myosin is not essential for the conformational transition, but is required for the phosphorylation-dependent regulation of enzymatic activity and filament assembly.
Stability of the Two-phase Structure of the Hard Particles in Ti(C, N) Base Cermets and Diffusional Phenomena in Ti(C, N)-(Ti, Mo)C Diffusion Couples. (1996)

In order to study the phase stability of the hard particle grains in cermet cutting materials (Ti, Mo)(C, N)-Ni cermets were heat treated at 1393K for 7.2 × 103 ks (2000h). The microstructurel changes were compared to the changes observed in nitrogen free (Ti, Mo)C-Ni cermets under otherwise identical conditions. (Ti, Mo)C-Ti(C, N) and (Ti, Mo)C-TiC diffusion couples were also prepared and heat treated at 2023 and 2173 K. Surprisingly, the (Ti, Mo)C-Ti(C, N) diffusion couple showed faster diffusion kinetics than the (Ti, Mo)C-TiC couple. A mechanism based on the chemical interaction of Mo and N atoms was proposed for this phenomenon.
Variable product purity and functional capacity after CD34 selection: a direct comparison of the CliniMACS<sup>®</sup> (v2·1) and Isolex<sup>®</sup> 300i (v2·5) clinical scale devices (2002)

The two clinical scale devices currently available for CD34+ cell selection from peripheral blood stem cells (PBSC) apheresis products, the CliniMACS and the Isolex 300i, were compared directly by pooling and splitting two PBSC harvests collected on sequential days from 10 patients and processing half of each pooled harvest on each device. The CliniMACS product had significantly higher median CD34+ purity (90%vs 78%; P = 0.004) and lower median T-cell content (0.06%vs 0.44%; P = 0.003) compared with the Isolex 300i product. The median CD34+ yields were similar (64% and 60% respectively). However, when the functional capacities of the products were compared, the median recovery of colony-forming units was significantly greater from the Isolex 300i product (48%vs 38%; P = 0.035), as was expansion of cells in either erythroid or granulocytic lineage-specific liquid culture (2.1-fold more erythroid and 1.5-fold more granulocytic lineage progenitors on d 9 (P = 0.03 and 0.03 respectively). This was due to a higher proportion of apoptotic cells in the CliniMACS product (28%vs 18%; P = 0.007, annexin V binding). Hence, although the CliniMACS device yielded a higher purity product with fewer T cells, the Isolex 300i product contained fewer apoptotic cells and consequently had greater functional capacity in culture.
THE CLEVELAND CLINIC CORAIDETM BLOOD PUMP WITHOUT ANTICOAGULATION THERAPY (2001)

Purpose: The Cleveland Clinic CorAideTM left ventricular assist system is based on a small implantable continuous flow centrifugal pump designed for long term circulatory support (5–10 years). From August to November 2000, we performed a series of calf in vivo studies to evaluate the biocompatibility effects of discontinuation of intravenous heparin anticoagulation therapy. Methods: Chronic CorAideTM blood pump implantation was performed in 4 calves (89.5 ± 4.9 kg). The inflow cannula was inserted into the left ventricular apex, and the outflow graft was anastomosed to the aorta without cardiopulmonary bypass. In all 4 calves, CorAideTM blood pump was positioned in the left chest cavity. During the early postoperative periods (2–7 days), intravenous heparin was used to maintain the activated clotting time values at approximately 1.2 times baseline. Heparin administration was then discontinued with no other anticoagulants or antiplatelet drugs given for the duration of the experiments. All animals were electively sacrificed and autopsy was performed at a mean 29 days postoperatively. Results: There was no incidence of mechanical failure, bleeding, or device infection. Hemolysis occurred in one calf due to outflow graft stenosis. The blood pump surfaces were clean in all 4 calves. Conclusion: These results suggest that the CorAideTM blood pump can be safely run with minimal or no anticoagulants. We will conduct 90 day duration studies to further document the use of the CorAideTM blood pump without anticoagulants.
Toxicity of two North American<i>Loxosceles</i>(brown recluse spiders) venoms and their neutralization by antivenoms (2007)

The toxic, biochemical, and immunological characteristics of L. boneti and L. reclusa venoms and its neutralization by anti-L. boneti and anti-L. reclusa antivenoms were studied. The electrophoretic profile showed very similar patterns and the toxic activities were very close. Immunological studies showed cross-reactivity among L. boneti and L. reclusa venoms, with L. boneti and L. reclusa experimental antivenoms, and anti-L. gaucho and anti-L. laeta antivenoms. The venom of L. laeta showed low immunological reactivity with the North American Loxosceles antivenoms. Experimental anti-North American Loxosceles antivenoms protected mice of the systemic toxicity and were able to prevent necrosis in rabbit skin after the injection of the venom. Both antivenoms displayed cross neutralization. The results showed that both Loxosceles venoms have very close toxic, biochemical, and immunological characteristics, and that either monospecific antivenoms or an antivenom raised with L. boneti and L. reclusa venoms as immunogens could be useful for treating bites by North American Loxosceles spiders.

3-Dimensional Lightning Observations Using a Time-of-Arrival Lightning Mapping System (2001)

A lightning mapping system has been developed that locates the sources of VHF radiation from lightning discharges in three spatial dimensions and time. The system consists of several VHF receivers distributed over an area of about 100 km diameter. The system locates VHF radiation sources over the array with an accuracy of about 100 m. The system locates sources out to 250 km from the center of the array with reduced accuracy. The observations are found to reflect the basic charge structure of electrified storms.
Human ETS2 gene on chromosome 21 is not rearranged in Alzheimer disease. (1988)

The human ETS2 gene, a member of the ETS gene family, with sequence homology with the retroviral ets sequence of the avian erythroblastosis retrovirus E26 is located on chromosome 21. Molecular genetic analysis of Down syndrome (DS) patients with partial trisomy 21 allowed us to reinforce the supposition that ETS2 may be a gene of the minimal DS genetic region. It was originally proposed that a duplication of a portion of the DS region represents the genetic basis of Alzheimer disease, a condition associated also with DS. No evidence of either rearrangements or duplications of ETS2 could be detected in DNA from fibroblasts and brain tissue of Alzheimer disease patients with either the sporadic or the familiar form of the disease. Thus, an altered ETS2 gene dosage does not seem to be a genetic cause or component of Alzheimer disease.
