Deep learning based adaptive sequential data augmentation technique for the optical network traffic synthesis (2019)

The lack of the sufficient and diverse training data is one of the main challenges limiting performances of the machine learning enabled applications in optical networks. Here, we propose a deep learning based sequential data augmentation technique for the aggregate traffic data augmentation for diverse optical network scenarios. A generative adversarial network (GAN) model is trained with the experimental traffic data to automatically extract the substantial characteristics of the experimental traffic data through the zero-sum game theory and then augment the traffic data adaptively. The statistical evaluation parameters of the augmented traffic are mean, variance and Hurst exponent. To add comparisons, two other classical generative models including the statistical parameter configuration (SPC) model and the variational autoencoder (VAE) model are also adopted to generate the traffic data that are similar to the actual traffic data. The comprehensive comparisons among the proposed GAN, the SPC and VAE show that the performances of the GAN exceed those of the SPC and the VAE obviously. The mean and the variance of the augmented traffic data from the GAN are almost equal to those of the experimental traffic data, where the average deviations are both within 2%. The Hurst exponent of the augmented traffic data from the GAN is respectively near 90% and 96% of those of the experimental traffic data in the access network and the core network. To estimate the similarity intuitively, the well-known k-mean algorithm is used to cluster the augmented traffic data according to the centroids determined by the corresponding experimental traffic data and the clustering accuracies are all higher than 95% for 6 kinds of typical traffic types in the optical networks. These results demonstrate that the proposed GAN is able to effectively generate the traffic data that is very close to the experimental traffic data and is difficult to be distinguished for diverse traffic types. Moreover, a relatively small dataset with a few hundred pieces of experimental traffic data is required and the amount of the augmented traffic data from the GAN is unlimited in theory, which can be augmented as much as we need. The proposed traffic data augmentation technique also has the potential to be utilized in other sequential data augmentation applications for the optical networks.
Rapid Preparation of Lead Titanate Sputtering Target Using Spark‐Plasma Sintering (2001)

PbTiO 3 sputtering targets 8 cm in diameter were prepared using spark‐plasma sintering (SPS) for relatively short periods, ∼2 min. Submicrometer‐sized PbTiO 3 powders with a relatively large size distribution were densified to ∼86% of the theoretical X‐ray density using the SPS process. In contrast, large‐sized (8 cm in diameter) ceramics could not be prepared from starting powders with a relatively narrow particle‐size distribution. Formation of cracks in the large PbTiO 3 targets was observed when samples were prepared under higher pressures (>50 MPa) or at higher temperatures (>900°C). Crack formation was attributed to unrelaxed internal stress originating from lower pore contents and from an inhomogeneous distribution of cations in the ceramics prepared under these conditions.
The end-effectors of preconditioning protection against myocardial cell death secondary to ischemia–reperfusion (2006)

Our understanding of the end-effectors involved in preconditioning protection is still very limited. This is partially due to an incomplete knowledge of the mechanisms responsible for acute sarcolemmal rupture and cell death during the first minutes of reperfusion, including the relative roles of hypercontracture-mediated sarcolemmal rupture and mitochondrial permeability transition pore (MPTP) opening-mediated cell death. In the present article, the role of proposed end-effectors of preconditioning protection, defined as molecules directly involved in cell death that are modified by ischemic preconditioning (IP), is examined. IP attenuates hypercontracture-mediated cell death, probably through several mechanisms, including attenuated calpain activation during reperfusion leading to preserved cytoskeletal integrity and accelerated recovery of Na+/K+-ATPase function, but probably also protein kinase G (PKG)-mediated improved calcium handling. The potential role of gap junctions in preconditioning protection is controversial, but the recently discovered mitochondrial localisation of connexin43 seems to play an important role in protection that has not yet been completely defined. Several recent studies suggest that IP can reduce MPTP opening during reperfusion and limit infarct size through this mechanism, although the contribution of this widely accepted mechanism to the infarct size reduction induced by IP in the intact heart needs to be established.
A Web-based Interactive Visual Graph Analytics Platform (2015)

This paper proposes a web-based visual graph analytics platform for interactive graph mining, visualization, and real-time exploration of networks. GraphVis is fast, intuitive, and flexible, combining interactive visualizations with analytic techniques to reveal important patterns and insights for sense making, reasoning, and decision making. Networks can be visualized and explored within seconds by simply drag-and-dropping a graph file into the web browser. The structure, properties, and patterns of the network are computed automatically and can be instantly explored in real-time. At the heart of GraphVis lies a multi-level interactive network visualization and analytics engine that allows for real-time graph mining and exploration across multiple levels of granularity simultaneously. Both the graph analytic and visualization techniques (at each level of granularity) are dynamic and interactive, with immediate and continuous visual feedback upon every user interaction (e.g., change of a slider for filtering). Furthermore, nodes, edges, and subgraphs are easily inserted, deleted or exported via a number of novel techniques and tools that make it extremely easy and flexible for exploring, testing hypothesis, and understanding networks in real-time over the web. A number of interactive visual graph analytic techniques are also proposed including interactive role discovery methods, community detection, as well as a number of novel block models for generating graphs with community structure. Finally, we also highlight other key aspects including filtering, querying, ranking, manipulating, exporting, partitioning, as well as tools for dynamic network analysis and visualization, interactive graph generators, and a variety of multi-level network analysis, summarization, and statistical techniques.
IN VIVO HEAT SHOCK PROTEIN ASSEMBLES WITH SEPTIC LIVER NF-κB/I-κB COMPLEX REGULATING NF-κB ACTIVITY (2005)

This study elucidates the mechanism through which heat shock treatment influences the outcome of sepsis. Post-heat shock sepsis was induced in rats by CLP 24 h after whole-body hyperthermia. Liver cytosolic and nuclear fractions were collected and analyzed in early and late sepsis rats (sacrificed 9 and 18 h after CLP, respectively). During sepsis, levels of I-kappaB and nuclear factor-kappaB (NF-kappaB) declined in the cytosol of liver, whereas NF-kappaB increased in nucleus. NF-kappaB activity was significantly enhanced during sepsis, and the products of NF-kappaB target genes, such as TNF-alpha and inducible nitric oxide synthase (iNOS), were overexpressed. Heat shock treatment, inducing heat shock protein synthesis, prevented down-regulation of cytosolic I-kappaB and decreased translocation of NF-kappaB into the nucleus. Therefore, the sepsis-induced acceleration of NF-kappaB activation was inhibited. Expression of TNF-alpha and iNOS mRNA was also down-regulated. Coimmunoprecipitation with anti-NF-kappaB (p65) and anti-IkappaB antibodies verified an assembling phenomenon of heat shock protein (HSP) 72 with NF-kappaB and I-kappaB. We suggest that the mechanism preventing septic activation of NF-kappaB is that oversynthesized HSP72 forms a complex with NF-kappaB/I-kappaB, thus inhibiting nuclear translocation of NF-kappaB. HSP72 appears to play a crucial protective role in modulating the gene expression controlled by NF-kappaB in sepsis.

<i>ABA‐Hypersensitive Germination1</i> encodes a protein phosphatase 2C, an essential component of abscisic acid signaling in Arabidopsis seed (2007)

The phytohormone abscisic acid (ABA) regulates physiologically important stress and developmental responses in plants. To reveal the mechanism of response to ABA, we isolated several novel ABA-hypersensitive Arabidopsis thaliana mutants, named ahg (ABA-hypersensitive germination). ahg1-1 mutants showed hypersensitivity to ABA, NaCl, KCl, mannitol, glucose and sucrose during germination and post-germination growth, but did not display any significant phenotypes in adult plants. ahg1-1 seeds accumulated slightly more ABA before stratification and showed increased seed dormancy. Map-based cloning of AHG1 revealed that ahg1-1 has a nonsense mutation in a gene encoding a novel protein phosphatase 2C (PP2C). We previously showed that the ahg3-1 mutant has a point mutation in the AtPP2CA gene, which encodes another PP2C that has a major role in the ABA response in seeds (Yoshida et al., 2006b). The levels of AHG1 mRNA were higher in dry seeds and increased during late seed maturation--an expression pattern similar to that of ABI5. Transcriptome analysis revealed that, in ABA-treated germinating seeds, many seed-specific genes and ABA-inducible genes were highly expressed in ahg1-1 and ahg3-1 mutants compared with the wild-type. Detailed analysis suggested differences between the functions of AHG1 and AHG3. Dozens of genes were expressed more strongly in the ahg1-1 mutant than in ahg3-1. Promoter-GUS analyses demonstrated both overlapping and distinct expression patterns in seed. In addition, the ahg1-1 ahg3-1 double mutant was more hypersensitive than either monogenic mutant. These results suggest that AHG1 has specific functions in seed development and germination, shared partly with AHG3.
Gas turbine sensor loop availability driven fall back strategies design (2015)

The design of a new heavy duty gas turbine may imply the exploitation of well proven, as well as, of new sensing technologies and approaches. Nevertheless a key driving point in bringing on the market some innovation resides in the opportunity to implement a flexible sensing system able to optimize the existing compromise among performance, safety, reliability, availability and maintenance (RAMS) parameters. This problem can be solved addressing the possible fall back strategies in case of single or multiple sensors failures through reliability and availability modeling. In this paper, an approach on the modeling of actual sensor configuration dynamic apportionment is presented by means of phase diagrams representation, with the aim of evaluating the advantages and the drawbacks linked to the choice of a certain sensing configuration despite of the sensor technology and relying on failure modes and failure and repair rates knowledge. The simulation results are presented for three different possible sensors configurations on a selected sensor monitoring chain used in gas turbine systems.

Pressured Mud Cap Drilling from A Semi-Submersible Drilling Rig (2005)

Abstract Pressured Mud Cap Drilling (PMCD) is an advanced technique to control wells which encounter heavy mud losses and has been applied on onshore and offshore wells with surface wellheads. The key to successfully apply the technique is the use of a Rotating Control Device (RCD), which is a technology taken from Under Balanced Drilling (UBD). PMCD has not been applied to date on subsea wells as rigging up the RCD on the drilling riser brings additional challenges compared to surface wells. Three subsea wells were drilled Offshore Sarawak, utilizing the PMCD technique. A detailed review was made to rig up an RCD on the drilling riser of a Semi-Submersible drilling rig. The riser between the subsea BOP and the RCD at surface formed a low-pressure system to control the well. The first 2 wells did not see any losses but on the 3rd well, total losses occurred and the system was activated. The final result gave reason to look back on a successful operation but also good learnings were made for future operations.
Light trapping effect of submicron surface textures in crystalline Si solar cells (2007)

Abstract Recently, submicron textures have been researched and applied to multicrystalline silicon solar cells in order to improve their optical performance. In this study, the antireflection and light trapping effects of submicron surface textures in crystalline Si (c‐Si) solar cells were quantitatively investigated by numerical simulations based on Maxwell's equations with a simple two‐dimensional (2D) surface grating model. The calculated results showed that the surface reflection loss can be effectively reduced by using submicron Si surface gratings with appropriate aspect ratios. On the other hand, higher order diffractions that are caused by surface gratings that increase optical path lengths and light absorption near the band gap wavelength are dominant only for those with periods greater than 0·5 µm. From these results, it was inferred that submicron textures are effective for light trapping as well as for antireflection in thin c‐Si solar cells if appropriate dimensions are chosen.

Potential Role for Direct Gene Transfer in the Enhancement of Fracture Healing (1998)

This paper describes the use of localized transient gene therapy for the augmentation of fracture healing. It introduces a method involving the delivery of plasmid deoxyribonucleic acid via a three dimensional matrix into a wound, with in vivo transfection of wound repair cells resulting, their subsequent expression of factors that condition the wound site and the promotion of healing. Based on experience with critical and noncritical defect models in small and large animals, the potential advantages of this approach are discussed and experimental evidence of promoting bone formation is provided. The studies show the potential of this technology not only to promote bone healing but also to repair or to regenerate other connective tissues.
<title>Improvement of axial resolution in optical coherence tomography by optical pupil filter</title> (2007)

Axial resolution is a key factor in optical coherence tomography (OCT). Biomedical applications will benefit from improved resolution and quality that ultrahigh resolution OCT can provide. Existing approaches to improve axial resolution of OCT mostly depend on new broadband light sources, which are always costly and inconvenient in instrumentation. In this paper we adopt an alternative method to enhance the axial resolution of OCT by combining coherence gate with optical superresolution. A three-zone phase pupil filter is designed and inserted into the sample arm of OCT. The depth responses measured demonstrate that an improvement of more than 15% in axial resolution is achieved in the proposed OCT system.
Design and analysis of a vertical axis wind turbine (2013)

In the past three decades, increasing attention has being put into wind turbines as a clean and green renewable energy alternative to fossil fuels. There are two main types of wind turbines, the Horizontal Axis Wind Turbine (HAWT) and Vertical Axis Wind Turbine (VAWT). Due to the advantages that the VAWT has over the HAWT in urban environments, this project serves to investigate on an experimental Delta Blade VAWT.\n\nWith a pair of leading-edge vortices on the top surface, the delta wing is able to continue generating lift at high angles of attack where conventional wing would have already experienced stall. In addition, the reverse delta wing shows similar trends. Hence, these subsonic characteristics of the delta wing were found applicable to a VAWT, incorporated into the Delta Blade VAWT.\n\nIn this project, a Delta Blade VAWT was designed and built for wind tunnel testing. Initially, the Delta Blade VAWT with standard delta blades obtained a maximum power coefficient of 0.0138. Several modifications were done to the Delta Blade VAWT to improve its performance. Eventually, with the optimal turbine blades, cropped delta blades with 45o TE deflection, the maximum power coefficient was able to improve to 0.0496 (217.93% increment). Wind tunnel testing for 360o aerodynamic data and water tunnel flow visualization were also done to justify these improvements in performance.\n\nAs a whole, the Delta Blade VAWT with optimal turbine blades is considered to be successful. It has great self-starting and self-sustaining capabilities even at low wind speeds of 4 m/s, due to its operating TSR range of 0.2 to 0.4. Hence, the Delta Blade VAWT can be said to suit a small-scale urban rooftop application.
A phase plate for transmission electron microscopy using the Aharonov-Bohm effect (2010)

The Aharonov-Bohm effect provides a way to change the phase difference between scattered and direct electron waves in the transmission electron microscope by 90 degrees, and so to convert phase variation into amplitude information. In a thin ring of magnetic material a continuous loop of azimuthal flux provides the state of lowest magnetic energy (the vortex state). Permanently-magnetized rings can maintain this flux pattern in the presence of a strong axial field such as that of a microscope objective lens. The radial width required for such a ring is of the order of 50 nm and so the radial fraction of the scattered electrons that is intercepted can be very small.
