A dynamic strategy for multiple stacks manipulation (2002)

A new method for manipulating multiple stacks based on a dynamic data structure is proposed. By using a simple data structure called ordered-heap, it is easy to simultaneously handle several variable-size stacks in a sequential area of memory. The performance of this method is much better than D. E. Knuth's (1973) method and Garwick's method. For instance, there are 10 stacks and memory size is 500. Improvement of the author's method will be approximately 2.5 times that of Garwick's and much more than this compared to Knuth's when a load factor of 80% is achieved. In addition, the method described has a stable performance whatever n and m are.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Baseline SCAT2 Assessment of Healthy Youth Student-Athletes (2014)

Subtle differences between age and sex have been identified in many components of the SCAT2 assessment. These differences may support the current evolution of concussion assessment tools to provide the most appropriate test. Baseline testing should be used when available, and clinicians should be aware of potential differences when using normalized values.
Major incidents on the French electric system: potentiality and curative measures studies (1993)

Electric systems security improvement considerations will motivate the grid designer to take the major failure risks into account. Electricite de France has therefore adopted a methodology based upon the study of possible degradation mechanisms and then, upon the verification of their plausibility, by simulating the system dynamic behavior. Only this approach can fit with the complexity of great meshed systems. It enabled the performance of a new protection device against losses of synchronism to be defined. This defence plan will be operational in 1995 on a part of the French system.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

Mutational and Radiographic Analysis of Pulmonary Disease Consistent with Lymphangioleiomyomatosis and Micronodular Pneumocyte Hyperplasia in Women with Tuberous Sclerosis (2001)

Lymphangioleiomyomatosis (LAM) and multifocal micronodular pneumocyte hyperplasia (MMPH) produce cystic and nodular disease, respectively, in the lungs of patients with tuberous sclerosis. The objective of this study was to prospectively characterize the prevalence, clinical presentation, and genetic basis of lung disease in TSC. We performed genotyping and computerized tomographic (CT) scanning of the chest on 23 asymptomatic women with tuberous sclerosis complex (TSC). Cystic pulmonary parenchymal changes consistent with LAM were found in nine patients (39%). These patients tended to be older than cyst-negative patients (31.9 +/- 7.6 yr versus 24.8 +/- 11.6 yr, p = 0.09). There was no correlation between presence of cysts and tobacco use, age at menarche, history of pregnancy, or estrogen-containing medications. Three of the cyst-positive patients had a prior history of pneumothorax. Pulmonary function studies revealed evidence of gas trapping but normal spirometric indices in the cyst-positive group. All nine cyst-positive patients had angiomyolipomas (AML), which were larger (p < 0.05) and more frequently required intervention (p = 0.08) than cyst-negative patients (8 of 14 with AMLs, p < 0.05). Ten patients (43%) had pulmonary parenchymal nodules. Pulmonary nodules were more common in women with cysts (78% versus 21%, p < 0.05), and 52% of all patients had either cystic or nodular changes. TSC2 mutations were identified in all cyst-positive patients who were tested (n = 8), whereas both TSC1 and TSC2 mutations were found in patients with nodular disease. Correlation of the mutational and radiographic data revealed one pair of sisters who were discordant for cystic disease, two mother- daughter pairs who were discordant for nodular disease, and no clear association between cyst development and a specific mutational type. This prospective analysis demonstrates that cystic and nodular pulmonary changes consistent with LAM and MMPH are common in women with TSC.
Immunohistochemical Localization of Erythropoietin and Its Receptor in the Developing Human Brain (1999)

We have previously shown erythropoietin (Epo) and its receptor (Epo-R) to be present in the fetal human central nervous system (CNS), and Epo to be present in the spinal fluid of normal preterm and term infants. To investigate the cellular specificities and developmental patterns of expression of these polypeptides in the human brain-areas that have not been well researched-we designed the following study. Human brains ranging in maturity from 5 weeks post-conception to adult were preserved at the time of elective abortion, surgical removal (tubal pregnancy, or removal for temporal lobe epilepsy), or autopsy. Immunohistochemistry was used to localize Epo and Epo-R reactivity in brains of different stages of development. Astrocytes, neurons, and microglia were identified in sequential tissue sections by specific antibodies. At 5 to 6 weeks post-conception, both Epo and Epo-R localized to cells in the periventricular germinal zone. At 10 weeks post-conception, Epo immunoreactivity was present throughout the cortical wall, with the most intense immunoreactivity present in the ventricular and subventricular zones. Epo-R, in contrast, was localized primarily to the subventricular zone, with little staining evident in the ventricular zone. In late fetal brains, Epo-R reactivity was most prominent in astrocytic cells, although modest reactivity was observed in certain neuron populations. In contrast, Epo staining localized primarily to neurons in fetal brains, although a subpopulation of astrocytes was also immunoreactive. In postnatal brains, both astrocyte and neuron populations were immunoreactive with antibodies to Epo-R and Epo. From these results it is clear that Epo and its receptor are present in the developing human brain as early as 5 weeks post-conception, and each protein shows a specific distribution that changes with development. We speculate that Epo is important in neurodevelopment, and that it also plays a role in brain homeostasis later in life, functioning in an autocrine or paracrine manner.
Improving heterologous production of phenylpropanoids in <i>Saccharomyces cerevisiae</i> by tackling an unwanted side reaction of Tsc13, an endogenous double bond reductase. (2017)

Phenylpropanoids, such as flavonoids and stilbenoids, are of great commercial interest, and their production in Saccharomyces cerevisiae is a very promising strategy. However, to achieve commercially viable production, each step of the process must be optimised. We looked at carbon loss, known to occur in the heterologous flavonoid pathway in yeast, and identified an endogenous enzyme, the enoyl reductase Tsc13, which turned out to be responsible for the accumulation of phloretic acid via reduction of p-coumaroyl-CoA. Tsc13 is an essential enzyme involved in fatty acid synthesis and cannot be deleted. Hence, two approaches were adopted in an attempt to reduce the side activity without disrupting the natural function: site saturation mutagenesis identified a number of amino acid changes which slightly increased flavonoid production but without reducing the formation of the side product. Conversely, the complementation of TSC13 by a plant gene homologue essentially eliminated the unwanted side reaction, while retaining the productivity of phenylpropanoids in a simulated fed batch fermentation.

Relationship between biotin-binding proteins from chicken plasma and egg yolk (1978)

The plasma of laying hens contains a specific biotin-binding protein that appears to be identical with an egg-yolk biotin-binding protein. Both proteins are saturated with biotin and require elevated temperatures to effect the exchange of [14C]biotin for the protein-bound vitamin. The heat-exchange curve in each case is the same and differs sharply from that of avidin, the egg-white biotin-binding protein. On Sephadex G-100 gel filtration, plasma and yolk biotin-binding proteins were each eluted slightly ahead of avidin (mol.wt. 68,000), suggesting that they are of similar molecular weight. Plasma and yolk biotin-binding proteins required the same ionic strength to be eluted from a phosphocellulose ion-exchange column. Both the plasma and yolk biotin-binding proteins had a pI of 5; avidin has a pI of 10. Plasma biotin-binding protein cross-reacted with antiserum to yolk biotin-binding protein and showed a precipitin line of identity with purified yolk biotin-binding protein. It is suggested that biotin-binding plays an important role in mediating the transport of the vitamin from the bloodstream to the developing oocyte.
Providencia friedericiana, a New Species Isolated from Penguins (1983)

The name Providencia friedericiana sp. nov. is proposed for a well-defined group of organisms that were isolated from fecal specimens from penguins (Aptenodytes patagonica, Eudyptes crestatus, Pyoscelis papua, Spheniscus demersus, and Spheniscus humboldti). P. friedericiana strains are gram-negative, oxidase-negative, fermentative rods that grow on Endo agar, MacConkey agar, Wilson-Blair agar, and some other selective media for Enterobacteriaceae. They are acetate, adonitol, arginine dihydrolase, gelatinase, inositol, lactose, lysine decarboxylase, mannitol, ornithine decarboxylase, tartrate, trehalose, urease, and Voges-Proskauer negative, but fructose, galactose, glucose, glycerol, indole, catalase, KCN, nitrate reductase, mannose, methyl red, and phenylalanine deaminase positive. Simmons citrate is utilized weakly and variably. Gas is produced from glucose in small amounts or not at all. The organisms possess flagella when they are grown at 25°C. They show moderate motility at 25°C but are nonmotile or only slightly motile at 36°C. Capsules and slime layers are not produced. The type strain of P. friedericiana, strain 1/33, has been deposited with the Deutsche Sammlung von Mikroorganismen as strain DSM 2620.
Preparation and Characterization of Lignin-Phenolic Foam (2011)

In this paper, lignin could partly replaced phenol to prepare lignin-phenolic(LPF) foam. The effects of amount of lignin on mechanical properties, thermal stability, fire-retardant and micro-structure of LPF foam. The results indicated that the addition of lignin decreased the brittleness and flexibility of foam, and the foam hole became larger in diameter and distributed more unevenly. When the lignin replacement amount was lower, the foam had regular foam hole structure and even distribution of foam hole, the size of foam hole increased with an increase of lignin content, SEM observations were in accordance with the early research of the mechanical properties of foams. And the addition of lignin slightly affected the fire-retardant and thermal stability of foam. When lignin replacement amount was 30% and 40%, the critical oxygen index of foam was even slightly higher than the pure PF foam.
Sensor Error Compensation in Engine Performance Diagnostics (1994)

The pursuit of reliable engine performance methods is as old as the gas turbine itself. Contemporary methods of engine fault isolation and assessment have centered around the use of modem estimation algorithms similar in nature to the Kalman filter and its derivatives. Those who are familar with such programs will offer the following quip, (apparently known to many but attributed to none), that the Kalman filter works well when you already know the answer, in other words, when the a-priori estimates are sufficiently close to the true values such as to produce small measurement residuals. Unfortunately, the ubiquity of measurement error ensures that this is generally not the case. A pivotal requirement for successful diagnostics becomes the ability to detect and assess the measurement error existing in raw engine data in an effort to mitigate its effect on potential engine fault mis-interpretation. The purpose of this paper is to outline the mathematical basis for the techniques in present use and to offer a generalization to a large measurement error compensation method which has been utilized effectively for over a decade.
Design and Analysis of Silicon Photonics Wave Guides Using Symbolic Methods (2015)

Although the demise of Moore's law has been predicted many times in the recent past, the emergence of silicon photonics has the potential to extend the lifetime of Moore's law significantly. Using conventional CMOS processing for the generation, routing, and processing of light waves, silicon photonics has finally brought the full power of photonics to very large scale integration (VLSI). However, along with these benefits, significant challenges in computer aided design of silicon photonics have also arisen. This paper presents a novel symbolic method based on Gröbner basis of tangent space polynomials of parametric curves to address these challenges. We analyze the design, optimization and verification of silicon photonic wave guides using parametric polynomials, and demonstrate the powerful method of Gröbner basis functions to solve complex problems such as envelope generation, rectification, manufacturability, singularity detection, reticle and etch processing model generation, tapering loss minimization, and bend loss minimization. We present the use of computer algebra systems such as MAXIMA and REDUCE, to analyze waveguide arrays. In addition, the methods presented in this paper can also be used for the analysis of curves arising from micro-electronic mechanical systems and micro-fluidics VLSI layouts.
Detection of moving objects from a moving platform in urban scenes (2010)

Moving object detection in urban scenes is important for the guidance of autonomous vehicles, robot navigation, and monitoring. In this paper moving objects are automatically detected using three sequential frames and tracked over a longer period. To this extend we modify the plane+parallax, fundamental matrix, and trifocal tensor algorithms to operate on three sequential frames automatically, and test their ability to detect moving objects in challenging urban scenes. Frame-to-frame correspondences are established with the use of SIFT keys. The keys that are consistently matched over three frames are used by the algorithms to distinguish between static objects and moving objects. The tracking of keys for the detected moving objects increases their reliability over time, which is quantified by our results. To evaluate the three different algorithms, we manually segment the moving objects in real world data and report the fraction of true positives versus false positives. Results show that the plane+parallax method performs very well on our datasets and we prove that our modification to this method outperforms the original method. The proposed combination of the advanced plane+parallax method with the trifocal tensor method improves on the moving object detection and their tracking for one of the four video sequences.
A novel approach to realizing flexible transport systems using reconfigurable hardware (2002)

This paper discusses a novel approach to realizing a flexible high speed signal transport system for the multimedia network. We propose a flexible transport system architecture based on reconfigurable hardware. The proposed architecture realizes all the functions needed for high speed telecommunication systems which include physical interfaces, programmable buffer memory, bi-directional processing, multiclock processing and co-processing using dedicated processors for higher layer processing. We develop an experimental prototype system using the custom designed reconfigurable hardware called PROTEUS. We also discuss a design methodology for achieving flexible transport systems. Experimental results for 156 Mbps SDH/ATM processing circuits are shown. Our experimental results show the feasibility of achieving both flexibility and high speed processing in high speed digital transport systems.
Growth conditions and superconductive properties of a-axis oriented YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// films on LaSrGaO/sub 4/ substrates (2001)

Summary form only given. In-plane aligned a-axis YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// (YBCO) films are needed for the investigation of the anisotropic properties of superconductors and their application to electron devices. However, usually a limited substrate temperature range is necessary for a-axis orientation. In this work the LaSrCaO/sub 4/ (LSGO) substrates were treated by ion-beams, then YBCO films were deposited by the temperature gradient method. It was found that surface cleaning by ion beam with 45 degree incident angle was effective. High quality a-axis oriented films were formed at the initial substrate temperature in the range of 520/spl deg/C-600/spl deg/C and final temperature of 680/spl deg/C. In-plane aligned a-axis oriented films were obtained at the initial substrate temperature in the range of 540/spl sim/570/spl deg/C. The in-plane aligned films have an anisotropic resistance of factor 21. Many jumps were observed in I-V characteristics along the c-axis which are attributed to the intrinsic Josephson effects.
Effect of interleukin 2, interferon-<i>gamma</i>, and mitogens on the production of tumor necrosis factors <i>alpha</i> and <i>beta</i>. (1985)

Human peripheral blood mononuclear cells (PBMC) were induced by recombinant interleukin 2 and mitogens to secrete two distinct cytotoxic polypeptides, tumor necrosis factor-alpha (TNF-alpha) and tumor necrosis factor-beta (TNF-beta), previously called lymphotoxin. Treatment of PBMC with recombinant human interleukin 2 (rIL 2) or mitogens in combination with recombinant human interferon-gamma (rIFN-gamma) resulted in augmented production of both TNF-alpha and TNF-beta. rIFN-gamma alone had no effect on production of either cytotoxic polypeptide. TNF-alpha was produced within 2 to 3 hr after induction and was the major cytotoxin produced by PBMC during the first 48 hr of culture, after which time TNF-beta became the predominant species. TNF-beta was first secreted into the media after 8 hr of induction. Enhanced levels of both TNF-alpha and TNF-beta were seen when the PBMC were separated into adherent and nonadherent cells. Both TNF-alpha and TNF-beta were induced in different tumor cell lines of hematopoietic origin. The results demonstrate that the production of TNF-alpha and TNF-beta can be enhanced by two lymphokines, IL 2 and IFN-gamma.
Some aspects of control loop performance monitoring (1994)

In industries where there are a great number of control loops, it would be convenient to have some tool for monitoring the performance of individual loops. This paper starts from one available approach that evaluates the control performance compared to minimum variance control. The authors show, using an example and also from industrial data, that this technique gives an inadequate measure of the performance if the aim is not stochastic control, but step disturbance rejection. Therefore, some modified criteria are proposed and a monitoring tool utilising all available techniques outlined.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Optimal Segmentation Strategy for Compact Representation of Hyperspectral Image Cubes (2000)

The reuse and separation of nanomaterials from an aquatic solution is always challenging and may cause nanotoxicity if not separated completely. Nanomaterial immobilization on the surface of a macro-size material could be an effective approach to developing an efficient composite for groundwater purification. Herein, polyaniline and graphene oxide nanosheet immobilized granular tea waste (PANI/GO@GTW) has been synthesized to remove the anionic and cationic contaminants from groundwater. The synthesized materials were characterized by SEM, XRD, XPS, and FTIR spectroscopies. The optimization of experimental conditions was tested for bromide (Br−) removal from synthetic water. The results revealed that Br− adsorption behavior onto the synthesized materials was as follows: PANI/GO < PANI/GTW < PANI < PANI/GO@GTW. The optimum removal of Br− ions was observed at pH 3 with 90 min of saturation time. Br− adsorption onto PANI/GO@GTW followed the pseudo-first-order kinetic and Langmuir isotherm model, and electrostatic interaction was involved in the adsorption process. The optimum adsorption of Br− onto PANI/GO@GTW was found to be 26.80 m/g. The application of PANI/GO@GTW on real groundwater treatment demonstrated the effective removal of anion pollutants such as F−, Cl−, Br−, NO3−, and PO43−. This study revealed that PANI/GO@GTW successfully reduced Br− concentrations in synthetic and real groundwater and can be used for large-scale applications.
