Power-aware dynamic task scheduling for heterogeneous accelerated clusters (2009)

Recent accelerators such as GPUs achieve better cost-performance and watt-performance ratio, while the range of their application is more limited than general CPUs. Thus heterogeneous clusters and supercomputers equipped both with accelerators and general CPUs are becoming popular, such as LANL's Roadrunner and our own TSUBAME supercomputer. Under the assumption that many applications will run both on CPUs and accelerators but with varying speed and power consumption characteristics, we propose a task scheduling scheme that optimize overall energy consumption of the system. We model task scheduling in terms of the scheduling makespan and energy to be consumed for each scheduling decision. We define acceleration factor to normalize the effect of acceleration per each task. The proposed scheme attempts to improve energy efficiency by effectively adjusting the schedule based on the acceleration factor. Although in the paper we adopted the popular EDP (Energy-Delay Product) as the optimization metric, our scheme is agnostic on the optimization function. Simulation studies on various sets of tasks with mixed acceleration factors, the overall makespan closely matched the theoretical optimal, while the energy consumption was reduced up to 13.8%.

Role of Energy Storage with Renewable Electricity Generation (2010)

Renewable energy sources, such as wind and solar, have vast potential to reduce dependence on fossil fuels and greenhouse gas emissions in the electric sector. Climate change concerns, state initiatives including renewable portfolio standards, and consumer efforts are resulting in increased deployments of both technologies. Both solar photovoltaics (PV) and wind energy have variable and uncertain (sometimes referred to as intermittent) output, which are unlike the dispatchable sources used for the majority of electricity generation in the United States. The variability of these sources has led to concerns regarding the reliability of an electric grid that derives a large fraction of its energy from these sources as well as the cost of reliably integrating large amounts of variable generation into the electric grid. In this report, we explore the role of energy storage in the electricity grid, focusing on the effects of large-scale deployment of variable renewable sources (primarily wind and solar energy).
Aspiration pneumonia and the laryngeal mask airway (1990)

A case of aspiration pneumonia is reported after the use of a laryngeal mask airway in a young woman undergoing an elective cholecystectomy. The case illustrates the hazards of regurgitation with the laryngeal mask airway and the need for further evaluation when used with controlled mechanical ventilation.
NAD synthesis from nicotinic acid by the hepatocytes prepared from diabetic rats. (1995)

Hepatocytes were prepared from rats 3 and 7 days after a single injection of streptozotocin (50 mg/kg) or alloxan (40 mg/kg). Using the hepatocytes, NAD-and total pyridine nucleotide-syntheses from [carboxyl-14C]-nicotinic acid were investigated. The NAD content of streptozotocin- or alloxan-treated hepatocytes was not significantly different from that of the control hepatocytes. Syntheses of NAD and total pyridine nucleotides from nicotinic acid were significantly elevated 3 days after streptozotocin-injection but only total pyridine nucleotide synthesis was significantly higher 7 days after streptozotocin. Only total pyridine nucleotide synthesis was elevated 3 days after alloxan. Differences in the effects of the two diabetogenic agents and the physiological meaning of an increased NAD synthesis from nicotinic acid in the liver of diabetic animals were discussed.

Fujisaki's Model of Fundamental Frequency Contours for Thai Dialects (2010)

Problem statement: In general, there are a number of rural dialects in Thai. However, four dialects are mainly spoken by Thai people residing in four core region including central, north, northeast and south regions. Recognizing and synthesizing Thai speech with different dialects are consequently difficult. Approach: Prosody is an important factor that must be taken into account, since the prosody effects on not only the naturalness but also the intelligibility of speech. To treat the problem, the speech prosody is carefully preserved through modeling the fundamental frequency (F0) contours. The differences among the model parameters of four Thai dialects have been summarized. This study proposed an analysis of model parameters for Thai speech prosody with four regional dialects and two genders which is a preliminary work for speech recognition and synthesis. Fujisaki's modeling; a powerful tool to model the F0 contour has been adopted. Seven derived parameters from the Fujisaki's model are as follows. The first parameter is baseline frequency which is the lowest level of F0 contour. The second and third parameters are the numbers of phrase commands and tone commands which reflect the frequencies of surges of the utterance in global and local levels, respectively. The fourth and fifth parameters are phrase command and tone command durations which reflect the speed of speaking and the length of a syllable, respectively. The sixth and seventh parameters are amplitudes of phrase command and tone command which reflect the energy of the global speech and the energy of local syllable. Results: In the experiments, each regional dialect includes 200 samples of one sentence with male and female speech. Therefore our speech database contains 1600 utterances in total. The results showed that most of the proposed parameters can distinguish four kinds of regional dialects explicitly. Conclusion: By using the Fujisaki's model, the results confirm that the proposed parameters can distinguish the regional dialects efficiently. In the future research, they were expected to be applied in the speech recognition and synthesis with various regional dialect characteristics.
The Use of Poly(Tetrafluoroethylene-Co-Hexafluoropropylene) Tubing as a Waveguide Capillary Cell for Liquid Absorption Spectrometry (1990)

An optical waveguide capillary cell (OWCC) has been used for signal enhancement in Raman scattering spectroscopy, colorimetry, and fluorometry. When the cell, hollow capillary tubing, is filled with a solvent that has a refractive index higher than that of the cell material, it forms a liquid-core optical fiber and it can be elongated to extreme length. Table I summarizes the refractive indices of various organic solvents and cell materials. As shown in the table, when capillary tubing made of borosilicate glass or quartz glass is used, only a few organic solvents such as carbon disulfide and toluene can be used—which greatly limits the applicability of this method.

An automated microfluidic system for single-stranded DNA preparation and magnetic bead-based microarray analysis (2015)

We present an integrated microfluidic device capable of performing single-stranded DNA (ssDNA) preparation and magnetic bead-based microarray analysis with a white-light detection for detecting mutations that account for hereditary hearing loss. The entire operation process, which includes loading of streptavidin-coated magnetic beads (MBs) and biotin-labeled polymerase chain reaction products, active dispersion of the MBs with DNA for binding, alkaline denaturation of DNA, dynamic hybridization of the bead-labeled ssDNA to a tag array, and white-light detection, can all be automatically accomplished in a single chamber of the microchip, which was operated on a self-contained instrument with all the necessary components for thermal control, fluidic control, and detection. Two novel mixing valves with embedded polydimethylsiloxane membranes, which can alternately generate a 3-μl pulse flow at a peak rate of around 160 mm/s, were integrated into the chip for thoroughly dispersing magnetic beads in 2 min. The binding efficiency of biotinylated oligonucleotides to beads was measured to be 80.6% of that obtained in a tube with the conventional method. To critically test the performance of this automated microsystem, we employed a commercial microarray-based detection kit for detecting nine mutation loci that account for hereditary hearing loss. The limit of detection of the microsystem was determined as 2.5 ng of input K562 standard genomic DNA using this kit. In addition, four blood samples obtained from persons with mutations were all correctly typed by our system in less than 45 min per run. The fully automated, "amplicon-in-answer-out" operation, together with the white-light detection, makes our system an excellent platform for low-cost, rapid genotyping in clinical diagnosis.
Vehicle trajectory clustering for traffic intersection surveillance (2016)

Traffic data obtained from surveillance system has been vital for traffic operators to monitor the traffic flow at a traffic intersection. However, detailed information of the traffic flow such as the behavioural manoeuvres is not sufficiently provided by the inductive-loop traffic detectors. Thus, vehicles trajectory dataset is selected as traffic data input in traffic simulation for modelling the traffic flow. In this paper, clustering on the vehicle trajectory dataset is simulated to group the data via similarity function based on Longest Common Subsequence (LCSS). To evaluate the clustering result, Rand Index (RI) is implemented to compare the simulated result with the ground-truth result.
Characterization of a Brain Permeant Fluorescent Molecule and Visualization of Aβ Parenchymal Plaques, Using Real-Time Multiphoton Imaging in Transgenic Mice (2014)

Emerging paradigms mandate discovery of imaging agents for diagnosing Alzheimer's disease (AD) prior to appearance of clinical symptoms. To accomplish this objective, a novel heterocyclic molecule (4) was synthesized and validated as Aβ targeted probe. The agent shows labeling of numerous diffuse Aβ plaques in confirmed AD human brain tissues and traverses the blood-brain barrier to enable labeling of parenchymal Aβ plaques in live mice (APP(±)/PS1(±)) brains.
Base‐Induced Formation of Two Magnesium Metal‐Organic Framework Compounds with a Bifunctional Tetratopic Ligand (2008)

Abstract Two coordination polymers constructed from magnesium and the tetratopic organic linker 2,5‐dihydroxyterephthalic acid are reported, denominated CPO‐26‐Mg and CPO‐27‐Mg. The organic component carries two different types of protic functional groups. The degree of deprotonation of the organic component can be regulated by the amount of sodium hydroxide employed in the synthesis, thus determining which of the compounds forms. In CPO‐26‐Mg, only the carboxylic acid groups of the linker are deprotonated and take part in the construction of the three‐dimensional framework. The structure is non‐porous, and its topology is based on the PtS net. In CPO‐27‐Mg, both the carboxylic acid and the hydroxy groups are deprotonated and involved in the construction of a microporous three‐dimensional framework which is based on a honeycomb motif containing large solvent‐filled channels. The metal atoms are arranged in chiral chains along the intersection of the honeycomb and contain one water molecule in their coordination sphere, which allows for the creation of coordinatively unsaturated metal sites upon dehydration. CPO‐27‐Mg is a potentially useful lightweight adsorbent with a pore volume of 60 % of the total volume of the structure and an apparent Langmuir surface area of up to 1030 m 2 g –1 . Its thermal stability was investigated by thermogravimetry and variable‐temperature powder X‐ray diffraction, which shows framework degradation to commence at 160 °C in air, at 235 °C under nitrogen, and at 430 °C in a dynamic vacuum. Thermogravimetric dehydration and re‐hydration experiments at miscellaneous temperatures indicate that it is possible to obtain open metal sites in CPO‐27‐Mg, but the water is more tightly bound in this material than in the previously reported isostructural nickel compound.(© Wiley‐VCH Verlag GmbH & Co.

Self-starting and self-Q-switching dynamics of passively mode-locked Nd:YLF and Nd:YAG lasers (1993)

The semiconductor antiresonant Fabry–Perot saturable absorber (A-FPSA) has a bitemporal absorption response with a slow time component that is due to carrier recombination and a fast time component that is due to intraband thermalization. We demonstrate that the slow component provides the self-starting mechanism and without significant Kerr lens contribution the fast component is necessary for steady-state pulse formation in passively cw mode-locked solid-state lasers. The carrier lifetime of the bitemporal A-FPSA was varied by the molecular-beam-epitaxy growth temperature to characterize its influence on the self-starting and self-Q-switching dynamics of cw mode-locked Nd:YLF and Nd:YAG lasers. The A-FPSA carrier lifetime and the top reflector of the A-FPSA can be adjusted to optimize the self-starting performance and to prevent self-Q-switching of cw mode-locked solid-state lasers.
Query by Browsing: A Visual Query Language Based on the Relational Model and the Desktop User Interface Paradigm (2008)

Abstract. Query by Browsing (QBB) is a visual query language that combines concepts from the relational model and the ubiquitous desktop user interface paradigm. It is a relationally complete method with recursive query capabilities that allows the creation of complex intentional and extensional queries using a direct manipulation interface that resembles a file browser in a modern operating system. In this paper we introduce the QBB paradigm and describe the reasons behind its inception. We also briefly discuss Chiromancer, an implementation of the QBB paradigm on the Palm platform that is underway and which to our knowledge is the first relationally complete visual query interface for a handheld device 1.
Towards automated production and drug sensitivity testing using scaffold‐free spherical tumor microtissues (2011)

Although the relevance of three-dimensional (3-D) culture has been recognized for years and exploited at an academic level, its translation to industrial applications has been slow. The development of reliable high-throughput technologies is clearly a prerequisite for the industrial implementation of 3-D models. In this study the robustness of spherical microtissue production and drug testing in a 96-well hanging-drop multiwell plate format was assessed on a standard 96-well channel robotic platform. Microtissue models derived from six different cell lines were produced and characterized according to their growth profile and morphology displaying high-density tissue-like reformation and growth over at least 15 days. The colon cancer cell line HCT116 was chosen as a model to assess microtissue-based assay reproducibility. Within three individual production batches the size variations of the produced microtissues were below 5%. Reliability of the microtissue-based assay was tested using two reference compounds, staurosporine and chlorambucil. In four independent drug testings the calculated IC(50) values were benchmarked against 2-D multiwell testings displaying similar consistency. The technology presented here for the automated production of a variety of microtissues for efficacy testing in a standard 96-well format will aid the implementation of more organotypic models at an early time point in the drug discovery process.
Unlocking Smart Phone through Handwaving Biometrics (2014)

Screen locking/unlocking is important for modern smart phones to avoid the unintentional operations and secure the personal stuff. Once the phone is locked, the user should take a specific action or provide some secret information to unlock the phone. The existing unlocking approaches can be categorized into four groups: motion, password, pattern, and fingerprint. Existing approaches do not support smart phones well due to the deficiency of security, high cost, and poor usability. We collect 200 users' handwaving actions with their smart phones and discover an appealing observation: the waving pattern of a person is kind of unique, stable and distinguishable. In this paper, we propose OpenSesame, which employs the users' waving patterns for locking/unlocking. The key feature of our system lies in using four fine-grained and statistic features of handwaving to verify users. Moreover, we utilize support vector machine (SVM) for accurate and fast classification. Our technique is robust compatible across different brands of smart phones, without the need of any specialized hardware. Results from comprehensive experiments show that the mean false positive rate of OpenSesame is around 15 percent, while the false negative rate is lower than 8 percent.

Allocation of raffinose family oligosaccharides to transport and storage pools in Ajuga reptans: the roles of two distinct galactinol synthases (2000)

Raffinose family oligosaccharides (RFOs) are important phloem transport and storage carbohydrates for many plants. Ajuga reptans, a frost-hardy evergreen labiate, ideally combines these two physiological roles and served as our model plant to study the regulation and importance of RFO metabolism. Galactinol is the galactosyl donor for the synthesis of raffinose (RFO-trisaccharide) and stachyose (RFO-tetrasaccharide), and its synthesis by galactinol synthase (GolS) is the first committed step of the RFO biosynthetic pathway. Two cDNAs encoding two distinct GolS were isolated from A. reptans source and sink leaves, designated GolS-1 and GolS-2, respectively. Warm- and cold-grown sink and source leaves were compared, revealing both isoforms to be cold-inducible and GolS-1 to be source leaf-specific; GolS-1 expression correlated positively with GolS activity. Conversely, GolS-2 expression was comparatively much lower and its contribution to the total extractable GolS activity is most probably only minor. These observations, together with results from phloem exudation and leaf shading experiments suggest that GolS-1 is mainly involved in the synthesis of storage RFOs and GolS-2 in the synthesis of transport RFOs. Furthermore, in situ hybridization studies showed GolS-1 to be primarily expressed in the mesophyll, the site of RFO storage, and GolS-2 in the phloem-associated intermediary cells known for their role in RFO phloem loading. A model depicting the spatial compartmentation of the two GolS isoforms is proposed.
Composite interface analysis using voltage contrast XPS (1993)

Abstract Voltage contrast x‐ray photoelectron spectroscopy (XPS) was developed to characterize the interfacial bonding properties in carbon fiber‐reinforced polymer matrix composites. The differing electrical properties of the fiber and matrix allow biasing of the matrix and separation of the fiber and matrix signals in the XPS spectrum. The result is a quantitative measure of the relative amount of exposed fiber and exposed matrix at the fracture surface of a failed composite specimen. A parameter used to describe the interfacial bonding is defined as the ratio of the areas of the carbon 1s peaks from the fiber and matrix components and is referred to as the interfacial bonding ratio or C f / C m . Typical values of C f / C m for polyacrylonitrile‐based carbon fiber‐reinforced polymer matrix composites range from zero (excellent bonding) to three (poor bonding). The voltage contrast technique was used to demonstrate the effects of matrix resin chemistry, electrolytic oxidative fiber surface treatment, fiber processing temperature, fiber modulus and hydrothermal damage on interfacial bonding.
Lethality in a Murine Model of Pulmonary Anthrax is Reduced by Combining Nuclear Transport Modifier with Antimicrobial Therapy (2012)

We demonstrate, for the first time, that regulating nuclear transport with a cell-penetrating modifier provides a cytoprotective effect, which enables the host's immune system to reduce its susceptibility to lethal B. anthracis infection. Thus, by combining a nuclear transport modifier with antimicrobial therapy we offer a novel adjunctive measure to control florid pulmonary anthrax disease.
