Rawls Scheduler: Load Considered Proportional Share Scheduling for High Performance Multimedia Systems (2010)

A scheduler for high performance systems containing mixed applications of both real-time multimedia and non real-time applications is proposed. The requirements of our proposed scheduler are twofold, i) all tasks, although the task is a non real-time task with a lower priority, never meet a starvation. ii) any tasks with a higher priority must occupy more CPU resource than any other tasks with lower priority (proportional share scheduler). Although legacy schedulers do not meet the requirements simultaneously, our proposed scheduler effectively satisfies our requirements simultaneously. Our implementation is evaluated with other schedulers such as Multi-level Queue, Multi-level Feedback Queue, and Two-Stage scheduler.
Reactive ion etching of copper in SiCl4-based plasmas (1991)

Copper may become an alternative to aluminum as an interconnect material in ultralarge scale integration multilevel metallization schemes if it is possible to pattern Cu by dry etching in a manufacturable process. Here we report results on the reactive ion etching of Cu in SiCl4/Ar and SiCl4/N2 plasmas. Etching has been investigated as a function of gas composition, pressure, and substrate temperature. We have obtained etch rates as high as 850 Å/min using SiCl4/N2 and a substrate temperature of ∼ 220 °C, with excellent etch selectivity of Cu relative to polyimide and SiO2. We demonstrate that it is feasible to pattern Cu anisotropically using polyimide as a high-temperature etch mask.
IMPROVING NEURAL NET TRAINING BY MATHEMATICAL OPTIMIZATION (1992)

Abstract Multilayer perceptrons are popular neural net models that are frequently used for classification tasks. Unfortunately, the standard training methods (backpropagation algorithm and variants thereof) are often numerically inefficient and unstable and need ad hoc tuning. In contrast to these methods, in this paper mathematically profound optimization techniques are applied: a combination of conjugate gradient methods, quasi-Newton methods, and several line search algorithms. This leads to considerable improvements over the backpropagation algorithm on various training data sets (parity problem, phoneme classification, recognition of handwritten characters).
Multiphoton Intravital Microscopy of Mandibular Draining Lymph Nodes: A Mouse Model to Study Corneal Immune Responses (2020)

Multiphoton intravital microscopy (MP-IVM) is a powerful tool to image cells <i>in vivo</i>. Its application in immunology research has opened new horizons, allowing intravital imaging of leukocytes at the single-cell level. A transparent cornea is vital to retain vision. As an immune privileged site, a rapid innate response to foreign antigens is crucial in clearing opportunistic bacterial and viral pathogens, and minimizing collateral structural damage to the cornea. Furthermore, dissecting the mechanisms and preventing the immunological rejection process after corneal transplantation is imperative to retain sight. Therefore, understanding the underlying mechanisms behind corneal immunity, specifically the process of antigen presentation and adaptive immunity in the mandibular draining lymph nodes (dLNs) <i>in vivo</i>, is crucial. Attempts of intravital imaging of mandibular dLNs have yielded little success to date, due to breathing artifacts and the location that is difficult to access. Herein, we present the first MP-IVM mouse model of the mandibular dLNs, utilizing transgenic mice in which CD11c<sup>+</sup> cells are fluorescently labeled. Furthermore, we demonstrate that CD11c-YFP<sup>+</sup> cells are localized mainly in the parafollicular cortex (T cell zone) and subcapsular area and are sparsely distributed in the follicular region (B cell zone) of mandibular dLNs during steady state. A significant increase in host CD11c-YFP<sup>+</sup> cell density is noted at 14 and 21 days following allogeneic corneal transplantation, compared to steady state (<i>p</i> < 0.05). Moreover, allogeneic corneal transplantation results in increased host-derived CD11c-YFP<sup>+</sup> cell mean speed and displacement in mandibular dLNs, compared to steady state (<i>p</i> < 0.001). The meandering index, an index for directionality, is significantly increased after allogeneic corneal transplantation at both 14 and 21 days, compared to steady state (<i>p</i> < 0.001). Taken together, our study demonstrates the necessary methodology required for intravital multiphoton imaging of the mandibular dLNs, allowing visualization of spatiotemporal kinetics of immune cells <i>in vivo</i>, and provides a window into the corneal immune reflex arc. This technique will be a powerful tool to investigate the pathogenesis of ocular immune and inflammatory diseases.
Effect of single doped 8YSZ powder on its emissivity in 3-5 μm wavelengths (2015)

8YSZ powder was respectively doped by ZnO,Al2O3 and Mo O3 via high temperature solid phase method. The effect mechanism of single-doped powder emissivity was analyzed by XRD and SEM. It is found that emissivity value of the doped powder decreases continuously from room temperature to 600 ℃ in the wavelengths of 3-5 μm. The emissivity of 8YSZ powder is improved integrally when doped by Al2O3,while the emissivity of the 8YSZ powders is reduced when doped by ZnO and Mo O3.The emissivity comes to the lowest value when doped with Mo O3 at molar volume of 5%,and it can be reduced to 0.249 at 600 ℃.
Dielectric Constant Logging, A Salinity Independent Estimation of Formation Water Volume (1975)

American Institute of Mining, Metallurgical, and Petroleum Engineers, Inc. Discussion of this paper is invited. Three copies of any discussion should be sent to the Society of Petroleum Engineers office. Such discussion may be presented at the above meeting and, with the paper, may be considered for publication in one of the two SPE magazines. Abstract A knowledge of the dielectric constant of earth materials provides a potential method of directly measuring formation water saturation. Dielectric logging has been studied theoretically and experimentally in order to supply this valuable knowledge. Laboratory core measurements, theoretical borehole-system computer models, instrument design and a detailed field example are combined to illuminate the concepts and demonstrate the value of dielectric constant logging. Introduction An open hole logging method which directly distinguishes oil from water in formations having low or unknown water salinity has been needed for many years. A potential technique for solving this problem relies upon a determination of the dielectric constant of the formation. Dielectric constant is a basic electrical property of matter for which oil and water have distinctly different characteristics. It is measured in units of farads per meter. It is well known that resistivity log interpretations are dependent upon a knowledge of formation water salinity. Unknown or variable salinity often leads to ambiguity in the log interpretation. Dielectric constant measurements can circumvent this problem because the formation dielectric constant is primarily determined by the water volume, not the water salinity. Large water volumes produce high dielectric constant values, and small volumes produce low dielectric values. produce low dielectric values. Efforts to build logging systems which measure formation dielectric constant have been underway. Russian scientists have been active in this field for several years and have published papers on the subject. published papers on the subject. The various aspects of dielectric logging have been discussed separately in these publications.
Biochemical Characterization of Polypeptides Encoded by Mutated Human Ha-ras1 Genes (1986)

We expressed six forms of p21-ras polypeptides in Escherichia coli with differing transformation potentials resulting from amino acid substitutions at position 12. The ability of the encoded p21's to autophosphorylate, bind guanine nucleotides, and hydrolyze GTP was assessed. All versions of p21 bound GTP equivalently; the kinase activity, while dependent upon residue 12, did not correlate with the transforming potential of the polypeptide. All transforming versions exhibited an impaired GTPase activity, while a novel nontransforming derivative [p21(pro-12)] possessed an enhanced GTPase activity. These results provide strong support for the proposal that an impairment of the cellular p21 GTPase activity can unmask its transforming potential.
A computational approach to the characterization of a microfluidic device for continuous size-based inertial sorting (2017)

The application of fully-inertial size-based microfluidic filtration technologies for particle separation is an attractive tool, which not only offers label-free control of the microenvironment during separation, but also facilitates integration and automation for high throughput sample processing. In this work, we exploit 3D computational fluid dynamics (CFD) simulations based on the lattice Boltzmann method to evaluate the performance of a microfluidic device specifically designed to trap and extract particles by inertial focusing and microscale vortices. The device geometry consists of a straight microchannel, followed downstream by a microchamber with outlets for continuous size-based separation. Simulations were carried out to characterize the flow properties of the microfluidic device. Here, the influence of the Reynolds number (Re), the chamber dimensions and the outlet channels aspect ratio on the streamtracer distribution were studied. In order to support the simulation results, some preliminary experimental validations have been conducted, finding that the model can accurately characterize the flow in the studied geometry. The results of the simulations and experiments presented in this paper can be very useful to support the design of continuous-flow particle sorting lab-on-a-chip (LOC) devices.
Research Note: Salmonella Decontamination of Broiler Carcasses with Lactic Acid, L-Cysteine, and Hydrogen Peroxide (1987)

Experiments on salmonella decontamination of broiler carcasses with lactic acid, L-cysteine, and hydrogen peroxide were performed. Treatment with lactic acid (1%) and hydrogen peroxide (.5%) resulted in a 4-log cycle reduction in colony forming units of Salmonella typhimurium both with pure cultures and with artificially inoculated broiler carcasses. L-cysteine was nonbactericidal in these experiments.

Computer simulation of the circulatory system during support with a rotary blood pump. (1991)

In order to investigate the performance characteristics of nonpulsatile centrifugal pumps and their interaction with the pulsating heart, a computer simulation model was developed. A model of the pump, including the cannulae and the interference of the cannula and the left atrial wall, was added to a simulator of the circulation. It was implemented on a PC-AT using the analog simulating software AGO1000. An interval of 1 msec real-time per calculation step was evaluated to provide stable results. The calculation speed was approximately 100 msec per step. First simulation studies showed that both the positioning and resistance of the cannulae exert a major influence on system performance and equalized the different pressure-flow characteristics of vaneless and impeller pumps (difference of dp/dQ decreases from more than 6 times without cannulae to 130% with cannulae). In addition, the effects of suction in the atrial cannula, and changes of ventricular performance during changes in pumping power, could be properly simulated. The comparison with animal tests proved that the model is a suitable tool for testing control algorithms for centrifugal pumps.
Gas-Liquid Chromatographic Determination of Maleic Hydrazide in Tobacco and Tobacco Smoke (1979)

Abstract A method is presented for the determination of the plant growth regulator maleic hydrazide (MH; l,2-dihydro-3,6-pyridazinedione) in tobacco and tobacco smoke. Residues are converted to the bis(trimethylsilyl) derivative before analysis by gas-liquid chromatography. The method has been applied to cigarettes and condensed smoke and has been used to determine the per cent transfer of MH into cigarette smoke. Free MH residues could be determined directly on the tobacco samples, whereas total MH values were obtainable only after acid hydrolysis. In spite of large MH residues in tobacco, only 0.2% of the MH was transferred into smoke.
Effect of Temperature on Synthesis of ZIF-8 Membranes for Propylene/propane Separation by Counter Diffusion Method (2015)

The counter diffusion method is a promising approach for the preparation of zeolitic imidazolate framework-8 (ZIF-8) membranes for propylene/propane separation. The effects of the reaction temperature on the structure and permeation properties of ZIF-8 membranes were evaluated to explore the mechanism of membrane formation. ZIF-8 membranes were prepared by the counter diffusion method using dimethylformamide as a solvent in order to control the reaction temperature within the range 25-125 °C. The ZIF-8 formation reaction and interdiffusion of the solutes are facilitated at higher reaction temperatures; the opposing effects of these factors strongly influence the membrane structure and permeation properties. The thickness of the ZIF-8 layer formed in the outermost section of the resultant ZIF-8 membranes decreased from 70 to 40 μm and was characterized by a definite layer structures with increasing reaction temperature. A propylene permeance of 2.2 × 10−9 mol m−2 s−1 Pa−1 with a propylene propane selectivity of around 10 was obtained in the binary gas permeation analysis of the ZIF-8 membrane prepared at 100 °C. The structure of the membranes and the effect of the total feed pressure, propylene fraction in the feed, and temperature dependence on the binary permeation properties were thoroughly characterized.
HEAD-NECK RESPONSE IN FRONTAL FLEXION (1984)

At the 27th Stapp conference on analysis was presented of human head-neck motion in lateral flexion. Based on this analysis performance requirements for mechanical necks in this type of impact were formulated. This study extends the analysis to head-neck response in frontal flexion. Results will be presented of dynamical tests with human subjects conducted by the Naval Biodynamics Laboratory (NBDL) in the Orleans. Two of these subjects were also included in the analysis of lateral flexion. It will be shown that the mechanical (mathematical) system with two ball and socket joints describing the head-neck response in lateral flexion is also suitable for forward flexion. Geometrical parameters are identical for both impact directions in contrast to the dynamical properties which show significant differences. By this mechanical analog the observed head-neck motions are completely defined. Results will be compared with earlier performance requirements proposed by Mertz et al. Evaluations of the part 572 and Hybrid III head-neck systems show that both necks are stiffer than any of the volunteers in the inpact ranges tested. For the covering abstract of the conference see TRIS 399532. (Author/TRRL)
Collagen- and Fibronectin-Mimetic Integrin-Specific Surfaces That Promote Osseointegration (2006)

Cell adhesion to the extracellular matrix through cell-surface integrin receptors is essential to development, wound healing, and tissue remodeling and therefore represents a central theme in the design of bioactive surfaces that successfully interface with the body. This is especially significant in the areas of integrative implant coatings since adhesion triggers signals that regulate cell cycle progression and differentiation in multiple cellular systems. The interactions of osteoblasts with their surrounding extracellular matrix are essential for skeletal development and homeostasis and the maintenance of the mature osteoblastic phenotype. Our objective was to engineer integrin-specific bioactive surfaces that support osteoblastic differentiation and promote osseointegration by mimicking these interactions. We target two specific integrins essential to osteoblast differentiation the type I collagen receptor alpha2beta1 and the fibronectin receptor alpha5beta1. The central hypothesis of this project was that the controlled presentation of type I collagen and fibronectin binding domains onto well-defined substrates would result in integrin-specific bioadhesive surfaces that support osteoblastic differentiation, matrix mineralization, and osseointegration. We have demonstrated that these biomimetic peptides enhance bone formation and mechanical osseointegration on titanium implants in a rat tibia cortical bone model. We have also shown that the presentation of multiple integrin-binding ligands synergize to enhance intracellular signaling and proliferation. Finally, we demonstrate the advantage of the short biomimetic peptides over the native ECM proteins. This research is significant because it addresses current orthopaedic implant limitations by specifically targeting cellular responses that are critical to osteoblastic differentiation and bone formation. This biomolecular approach provides a versatile and robust strategy for developing bioactive surfaces that enhance bone repair and osseointegration of orthopaedic implants.

Neurostimulation in cluster headache: A review of current progress (2013)

The rationale behind these therapies is based on growing evidence from clinical, hormonal and neuroimaging studies. The overall results are encouraging, but unfortunately not all patients have benefited. All the mentioned therapies require weeks to months of stimulation for a prophylactic effect to occur, suggesting brain plasticity as a possible mechanism, and only stimulation of the sphenopalatine ganglion has demonstrated an acute, abortive effect. Predictors of effect for all modes of neurostimulation still need to be identified and in the future, the least invasive and most effective strategy must be preferred as first-line therapy for intractable chronic cluster headache.
Development and evaluation of oligonucleotide chip based on the 16S-23S rRNA gene spacer region for detection of pathogenic microorganisms associated with sepsis. (2010)

Oligonucleotide chips targeting the bacterial internal transcribed spacer region (ITS) of the 16S-23S rRNA gene, which contains genus- and species-specific regions, were developed and evaluated. Forty-three sequences were designed consisting of 1 universal, 3 Gram stain-specific, 9 genus-specific, and 30 species-specific probes. The specificity of the probes was confirmed using bacterial type strains including 54 of 52 species belonging to 18 genera. The performance of the probes was evaluated using 825 consecutive samples that were positive by blood culture in broth medium. Among the 825 clinical specimens, 708 (85.8%) were identified correctly by the oligonucleotide chip. Most (536 isolates, or 75.7%) were identified as staphylococci, Escherichia coli, or Klebsiella pneumoniae. Thirty-seven isolates (4.5%) did not bind to the corresponding specific probes. Most of these also were staphylococci, E. coli, or K. pneumoniae and accounted for 6.3% of total number of the species. Sixty-two specimens (7.5%) did not bind the genus- or species-specific probes because of lack of corresponding specific probes. Among them, Acinetobacter baumannii was the single most frequent isolate (26/62). The oligonucleotide chip was highly specific and sensitive in detecting the causative agents of bacteremia directly from positive blood cultures.
