Remote Interaction and scheduling aspects of cloud based streams (2009)

This paper reports on a project concerned with various aspects of stream processing based on distributed components. In earlier work, we have explored dynamic reconfiguration, distributed management and a web services interface for remote deployment and control of cloud-based streams. Here, we look at aspects of remote interaction between a ProActive distributed active object system and the University of Chicago Nimbus cloud, showing that it is a useful environment in which to explore effects of distribution on latency, and commenting on problems of interaction through a firewall. We summarize some performance results of stream processing in the Nimbus cloud, especially our mechanisms for latency tolerance in remote interaction, with network measurements to show their effectiveness. The major contribution of this paper is to look at aspects of scheduling our stream components in a cloud based computation, focusing on criteria for initial deployment of the stream on cloud resources, outlining attributes of cloud resources that can sensibly be used in making scheduling decisions, and working towards a "cost model" suitable for use by economic scheduling heuristics. For this, we make use of Grid-bus; we introduce our model of interaction with it, our preliminary implementation, and demonstration of the use of Gridbus for deployment.

Performance Test Results of the Supercritical CO2 Compressor for a New Gas Turbine Generating System (2010)

Supercritical carbon dioxide (S-CO2) gas turbines can generate power at high cycle thermal efficiency, even at modest temperatures of 500–550°C, because of their markedly reduced compressor work near the critical point. Furthermore, the reaction between Na and CO2 is milder than that between H2O and Na. A more reliable and economically advantageous power generation system could be achieved by coupling with a sodium-cooled fast reactor. At Tokyo Institute of Technology, numerous development projects have been conducted for development of this system in cooperation with JAEA. Supercritical CO2 compressor performance test results are given as described herein. A centrifugal compressor is chosen for the performance test. Main compressor parts are stored in a pressure vessel. Maximum design conditions of the supercritical CO2 test apparatus are pressure of 11 MPa, temperature of 150°C, the flow rate of 6 kg/s and rotational speed of 24,000 rpm. The centrifugal compressor has an electric motor with permanent magnets on the rotor surface, with speed control by an inverter up to 24,000 rpm, a rotor shaft for the impeller, and a motor supported by gas bearings. Different compressor design points are examined using impellers of three kinds; test data are obtained using those impellers under steady state conditions with changing pressure, temperature, flow rate, and compressor rotor speed. The pressure ratio (compressor outlet pressure/inlet pressure) is obtained with the function of compressor rotational speed and the fluid flow rate. The data cover a broad region from sub-critical to supercritical pressure. Such data were obtained for the first time. No unstable phenomenon was observed in the area where the CO2 properties change sharply. Data of the pressure ratio vs. flow rate were coincident with the fundamental compressor theory.

The biochemical composition and transcriptome of cotyledons from Brassica napus lines expressing the AtGL3 transcription factor and exhibiting reduced flea beetle feeding (2018)

The study provides a roadmap for the isolation and identification of insect resistance compounds and proteins in the glabrous cotyledons of these hairy leaf lines. It also confirms the impact of mis-expression of GL3 and TTG1 on types of metabolism other than those associated with trichomes. Finally, the large number of up-regulated genes encoding heat shock proteins, PR proteins, protease inhibitors, glucosinolate synthesis/breakdown factors, abiotic stress factors, redox proteins, transcription factors, and proteins required for auxin metabolism also suggest that these cotyledons are now primed for resistance to other forms of biotic and abiotic stress.
0894 A Two Item Questionnaire Reflecting Parental Concern As An Indicator Of The Severity Of Obstructive Sleep Apnea In Children (2020)

Abstract Introduction The currently available questionnaires based on parental reporting of OSA symptoms include large number of items and are not sufficient to the diagnosis and assessment of OSA severity. We aimed to evaluate a simple 2-item questionnaire regarding parental concern as a predictor of the severity of OSA in children as measured by polysomnography. Methods Prospective analysis of parental concern regarding their children referred for PSG due to suspected OSA. Parents of all study children completed the brief Parental Concern Scale (PCS) questionnaire and the validated Pediatric Sleep Questionnaire-Sleep-Related Breathing Disorder questionnaire (PSQ-SRBD). The PCS consisted of 1 question on the need for surgery and 1 question on concerns about the child’s breathing. Results Ninety-five children (mean age 4.2 ± 2.5 years, 52% males, mean body mass index z score 0.45 ± 1.8) were recruited. Twenty-three children (24%) had moderate-severe OSA and were referred for adenotonsillectomy. Significant correlations were found between the need for surgery score and the apnea-hypopnea index (r=0.22, P = .029), as well as the mean SpO2 levels (r=-0.24, P = .02). The likelihood for the diagnosis of moderate-severe OSA by PSG increased as parental ranking for the need for surgery increased (P = .003). The need for surgery score and the child’s age were the only predictors for moderate-severe OSA (P = .01 and P = .043, respectively). Conclusion Querying parents on their perception of their child’s need for surgery is a sensitive, practical, and easy-to-use tool that can help the clinician in prioritizing referral to PSG. Support
Controlling the speed and direction of molecular motors that replicate DNA (2003)

The advent of techniques to detect and manipulate individual molecules has revealed that mechanical tension on a DNA polymer can control both the speed and direction of the DNA polymerase (DNAp) motor. Reconciling the interpretation of these single molecule experiments with crystal structural data has been the focus of our previous work. In more recent work, we are developing a more broadly applicable conceptual framework to describe how tension on a DNA polymer can produce both the "tuning" and "switching" phenomena observed in DNA polymerase motors. The chief aims are to elucidate the mechanism by which DNA replication is controlled in cells and to seek novel strategies for controlling molecular scale processes and the function of nanodevices.
Early-life stress biases responding to negatively valenced stimuli and increases amygdala volume and vulnerability to later-life stress (2022)

Abstract Early-life stress (ELS) or adversity, particularly in the form of childhood neglect and abuse, is associated with poor mental and physical health outcomes in adulthood. However, whether these relationships are mediated by the consequences of ELS itself or by other exposures that frequently co-occur with ELS is unclear. To address this question, we carried out a longitudinal study in rats to isolate the effects of ELS on regional brain volumes and behavioral phenotypes relevant to anxiety and depression. We used the repeated maternal separation (RMS) model of chronic ELS, and conducted behavioral measurements throughout adulthood, including of probabilistic reversal learning (PRL), responding on a progressive ratio task, sucrose preference, novelty preference, novelty reactivity, and putative anxiety-like behavior on the elevated plus maze. Our behavioral assessment was combined with magnetic resonance imaging (MRI) for quantitation of regional brain volumes at three time points: immediately following RMS, young adulthood without further stress, and late adulthood with further stress. We found that RMS caused long-lasting, sexually dimorphic biased responding to negatively-valenced stimuli on the PRL task. RMS also slowed response time on the PRL task, but without this directly impacting task performance. RMS animals were also uniquely sensitive to a second stressor, which further slowed and biased their responding on the PRL task. MRI at the time of the adult stress revealed a larger amygdala volume in RMS animals compared with controls. These behavioral and neurobiological effects persisted well into adulthood despite a lack of effects on conventional tests of ‘depression-like’ and ‘anxiety-like’ behavior, and a lack of any evidence of anhedonia. Our findings indicate that ELS has long-lasting cognitive and neurobehavioral effects that interact with stress in adulthood and may have relevance for understanding the etiology of anxiety and depression in humans.

MiRACLe: an individual-specific approach to improve microRNA-target prediction based on a random contact model (2020)

Deciphering microRNA (miRNA) targets is important for understanding the function of miRNAs as well as miRNA-based diagnostics and therapeutics. Given the highly cell-specific nature of miRNA regulation, recent computational approaches typically exploit expression data to identify the most physiologically relevant target messenger RNAs (mRNAs). Although effective, those methods usually require a large sample size to infer miRNA-mRNA interactions, thus limiting their applications in personalized medicine. In this study, we developed a novel miRNA target prediction algorithm called miRACLe (miRNA Analysis by a Contact modeL). It integrates sequence characteristics and RNA expression profiles into a random contact model, and determines the target preferences by relative probability of effective contacts in an individual-specific manner. Evaluation by a variety of measures shows that fitting TargetScan, a frequently used prediction tool, into the framework of miRACLe can improve its predictive power with a significant margin and consistently outperform other state-of-the-art methods in prediction accuracy, regulatory potential and biological relevance. Notably, the superiority of miRACLe is robust to various biological contexts, types of expression data and validation datasets, and the computation process is fast and efficient. Additionally, we show that the model can be readily applied to other sequence-based algorithms to improve their predictive power, such as DIANA-microT-CDS, miRanda-mirSVR and MirTarget4. MiRACLe is publicly available at https://github.com/PANWANG2014/miRACLe.
Ca2Al2SiO7 Crystalline Slab Waveguides from Surface Crystallized Glass. (2001)

Crystalline slab optical waveguides of a calcium aluminosilicate (Ca2Al2SiO7) were prepared by surface crystallization of a glass with close composition, upon heat treatment after an ultrasonic surface treatment (UST). Singlemode and multimode waveguides were obtained, by controlling the depth of the waveguides with both varying heat treatment temperature and time. The refractive index and optical propagation loss of the slab waveguides was also characterized.
Signaling By Fibroblast Growth Factors: The Inside Story (2001)

Polypeptide growth factors bind to the extracellular domains of cell surface receptors, triggering activation of receptor-intrinsic or receptor-associated protein kinases. Although this central thesis is widely accepted, one family of proteins, the fibroblast growth factors (FGFs), have for more than a decade attracted a research "counterculture" looking for direct FGF actions inside cells. Goldfarb discusses how the search for alternative signaling pathways is moving mainstream with the help of two recent publications reporting specific intracellular targets for FGF and FGF-like proteins.
An integrated runtime monitoring method for Internet-Based Virtual Computing Environment (2012)

This paper designs a new integrated runtime monitoring method for the Internet-Based Virtual Computing Environment (iVCE). This method consolidates basic state monitoring of virtual resources and application state monitoring of virtual tasks. To validate our methodology, we developed a monitoring system for an iVCE testbed of more than 1000 nodes.
Character animation from 2D pictures and 3D motion data (2007)

This article presents a new method to animate photos of 2D characters using 3D motion capture data. Given a single image of a person or essentially human-like subject, our method transfers the motion of a 3D skeleton onto the subject's 2D shape in image space, generating the impression of a realistic movement. We present robust solutions to reconstruct a projective camera model and a 3D model pose which matches best to the given 2D image. Depending on the reconstructed view, a 2D shape template is selected which enables the proper handling of occlusions. After fitting the template to the character in the input image, it is deformed as-rigid-as-possible by taking the projected 3D motion data into account. Unlike previous work, our method thereby correctly handles projective shape distortion. It works for images from arbitrary views and requires only a small amount of user interaction. We present animations of a diverse set of human (and nonhuman) characters with different types of motions, such as walking, jumping, or dancing.
Brain segmentation and white matter lesion detection in MR images. (1994)

This paper presents a review of methods and techniques that have been proposed for the segmentation of magnetic resonance (MR) images of the brain, with a special emphasis on the segmentation of white matter lesions. First, artifacts affecting MR images (noise, partial volume effect, and shading artifact) are reviewed and methods that have been proposed to correct for these artifacts are discussed. Next, a taxonomy of generic segmentation algorithms is presented, categorized as region-based, edge-based, and classification algorithms. For each category, the applications proposed in the literature are subdivided into 2-D, 3-D, or multimodal approaches. In each case, tables listing authors, bibliographic references, and methods used have been compiled and are presented. This description of segmentation algorithms is followed by a section on techniques proposed specifically for the analysis of white matter lesions. Finally, a section is dedicated to a review and a comparison of validation methods proposed to assess the accuracy and the reliability of the results obtained with various segmentation algorithms.
Evaluating Extraction and Storage of a Recombinant Protein Produced in Agroinfiltrated Lettuce (2006)

Extraction and storage of a recombinant protein produced by transient expression following agroinfiltration of lettuce were investigated. Lettuce leaves expressing beta-glucuronidase (GUS) were extracted by homogenization in several buffer combinations, and the yield and stability were assessed. The reducing agent dithiothreitol (DTT) was found to be the most important (significant) component in the extraction buffer. An extraction buffer consisting of 50 mM sodium phosphate at pH 7.0 with 10 mM DTT produced a good yield and stabilized GUS. Leaching of GUS through intact agroinfiltrated lettuce leaves was determined to be infeasible, with a maximum flux of 10 microg GUS/h/m2 and recovery of 1.7% of the GUS content in 24 h. Freeze-drying was evaluated as a method to extend the shelf life of the perishable leaf material containing GUS. First- and second-order kinetic models and the Weibull distribution were compared to describe inactivation of GUS in the freeze-dried leaves and leaf extracts. The first-order model best fit the inactivation data. An Arrhenius model fit the first-order inactivation data with respect to temperature with R2 = 1.00. Freeze-drying the lettuce leaves extended the estimated half-life of GUS to 69 days at 21 degrees C versus 11 days at 4 degrees C for fresh lettuce.
Photochemical Rearrangement of Chiral Oxaziridines in Continuous Flow: Application Toward the Scale-Up of a Chiral Bicyclic Lactam (2016)

A method for synthesizing chiral lactams from chiral oxaziridines in continuous flow is described. The oxaziridines are readily available from cyclic ketones. Photolysis of the oxaziridines using the Booker-Milburn flow system provides conversion to the chiral lactams in good yield and short residence times. Application of this chemistry toward the synthesis of a chiral bicyclic lactam is described.
Calibration of Laser Fluorescence Measurements of Lubricant Film Thickness in Engines (1988)

&lt;div class="htmlview paragraph"&gt;A laser fluorescent diagnostic method was employed to measure lubricant film thickness on the cylinder wall/piston interface of two engines. The system output signal was calibrated using lubricant samples of known thickness, and by comparison of a known piston ring profile to measured lubricant film contours. Agreement of the results of the two calibration methods was within 5%. A relative calibration was performed with three oils having different additive packages, and with an oil contaminated through use in a commercially operated engine. The calibration coefficients for the oils, relating output voltage to film thickness, varied within a factor up to two, depending on lubricant type and age.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The laser fluorescent apparatus was installed for use with a single cylinder test version of the Cummins VT-903 diesel engine. An optical passage was created through the block and cylinder wall using a quartz window. Preliminary results in the motored engine indicate a lubricant film thickness of approximately two microns, at the upper portion of the cylinder wall, on the minor-thrust face.&lt;/div&gt;
Scaling properties of conductance at integer quantum Hall plateau transitions (1998)

We investigate the scaling properties of zero-temperature conductances at integer quantum Hall plateau transitions in the lowest Landau band of a two-dimensional tight-binding model. Scaling is obeyed for all energy and system sizes with critical exponent $\ensuremath{\nu}\ensuremath{\approx}\frac{7}{3}$. The arithmetic average of the conductance at the localization-delocalization critical point is found to be $〈G{〉}_{c}{=0.506e}^{2}/h$, in agreement with the universal longitudinal conductance $〈{\ensuremath{\sigma}}_{\mathrm{xx}}〉=\frac{1}{2}{e}^{2}/h$ predicted by an analytical theory. The probability distribution of the conductance at the critical point is broad with a dip at small $G$.
Comparison of Enrichment and Plating Media for Isolation of Yersinia (1990)

Yersinia enterocolitica (Serotypes 0:3 or 0:8), Yersinia frederiksenii, Yersinia kristensenii, or Yersinia intermedia along with 10(8) cells of each of three extraneous organisms (Escherichia coli, Enterobacter aerogenes, Pseudomonas fragi), all commonly found on market poultry, were inoculated into five enrichment media followed by streaking onto 11 plating media to determine the most-efficacious combinations for future surveys or assessment studies. For Yersinia enterocolitica (0:8), infrequent recoveries were made using yeast extract-rosebengal-bile oxalate sorbose broth and phosphate-buffered saline (4 C) followed by plating onto pectin, DNase-Tween 80 (polyoxyethylene sorbitan monooleate)-sorbitol, MacConkey-Tween 80, or cefsulodin-irgasan-novobiocin (CIN) agars. With Y. enterocolitica (0:3), recoveries were most frequently made using phosphate-buffered saline, sorbitol bile (incubated for 17 days) and yeast extract-rosebengal-bile oxalate sorbose broth followed by plating onto pectin, CIN, bismuth sulfite (Difco Laboratories, Detroit, MI), or modified Rimler-Shotts agar. For Y. frederiksenii, Y. kristensenii, and Y. intermedia, incubation in sorbitol bile for 17 days or in yeast extract-rosebengal-bile oxalate sorbose broth, followed by plating onto CIN, pectin, DNase-Tween/80-sorbitol, cellobiose-arginine-lysine agar, or MacConkey-Tween 80 agar yielded the most-frequent recoveries. Overall, the CIN and pectin agars performed best for the recovery of the Yersinia bacterium; the modified selenite broth and the bismuth-sulfite plating agars were unsatisfactory in the present study.
Control strategies for dynamic voltage restorer compensating voltage sags with phase jump (2002)

Voltage sags are an important power quality problem and the dynamic voltage restorer is known as an effective device to mitigate voltage sags. In this paper, different control strategies for a dynamic voltage restorer are analyzed with emphasis put on the compensation of voltage sags with phase jump. Voltage sags accompanied by a phase jump are in some cases more likely to trip loads and a satisfactory voltage compensation are more difficult to achieve. Different control methods to compensate voltage sags with phase jump are proposed and compared. Two promising control methods are tested with simulations carried out in Saber and finally tested on a 10 kVA rated dynamic voltage restorer in the laboratory. Both methods can be used to reduce load voltage disturbances caused by voltage sags with phase jump. One method completely compensates the phase jump, which is the best solution for very sensitive loads. The second method does only partly compensate the phase jump, but it is expected to have a better performance in compensating a broader range of voltage sags.
