Machine and Component Residual Life Estimation through the Application of Neural Networks (2007)

This paper concerns the use of neural networks for predicting the residual life of machines and components. In addition, the advantage of using condition-monitoring data to enhance the predictive capability of these neural networks was also investigated. A number of neural network variations were trained and tested with the data of two different reliability-related datasets. The first dataset represents the renewal case where the failed unit is repaired and restored to a good-as-new condition. Data was collected in the laboratory by subjecting a series of similar test pieces to fatigue loading with a hydraulic actuator. The average prediction error of the various neural networks being compared varied from 431 to 841 seconds on this dataset, where test pieces had a characteristic life of 8,971 seconds. The second dataset was collected from a group of pumps used to circulate a water and magnetite solution within a plant. The data therefore originated from a repaired system affected by reliability degradation. When optimized, the multi-layer perceptron neural networks trained with the Levenberg-Marquardt algorithm and the general regression neural network produced a sum-of-squares error within 11.1% of each other. The potential for using neural networks for residual life prediction and the advantage of incorporating condition-based data into the model were proven for both examples.
Extending the Time Scale in Atomistic Simulation of Materials (2002)

▪ Abstract Obtaining a good atomistic description of diffusion dynamics in materials has been a daunting task owing to the time-scale limitations of the molecular dynamics method. We discuss promising new methods, derived from transition state theory, for accelerating molecular dynamics simulations of these infrequent-event processes. These methods, hyperdynamics, parallel replica dynamics, temperature-accelerated dynamics, and on-the-fly kinetic Monte Carlo, can reach simulation times several orders of magnitude longer than direct molecular dynamics while retaining full atomistic detail. Most applications so far have involved surface diffusion and growth, but it is clear that these methods can address a wide range of materials problems.
A Safe and Effective Paradigm to Functionally Map the Cortex in Childhood (1992)

Conventional cortical stimulation based on pulses of fixed duration briefer than the chronaxie rarely elicit responses in infants and young children. We developed a stimulation paradigm that relies on increments in both stimulus intensity and pulse duration. This approach ensures that stimulation parameters converge to the chronaxie by mathematically minimizing the energy required to elicit a response. In six patients, this paradigm successfully elicited clinical responses and/or afterdischarges at thresholds 5-8 mA below the standard paradigm and at up to 64% lower energy levels. Furthermore, three patients under age 5 years who did not respond to maximal fixed duration stimulation demonstrated afterdischarges and clinical responses when longer pulse durations were utilized. These findings indicate that a paradigm based on dual increments is effective for cortical mapping in children. Furthermore, by ensuring responses at lower energy levels, it may be more efficient for mapping the cortex at all ages.

Looking for Something to Signify (2020)

The behaviors and actions that an individual carries out in their daily life and how they are translated by their society overdetermine the gender one might have—or not—according to social norms. However, do the postulates enounced by feminist and queer Western thinkers still maintain their validity when the context changes? Can the performances of gender carry out their validity when the landscape is other than the one in Europe or the United States? And how can the context of drag complicate these matters? These are the questions that this article will try to answer by analyzing the 2015 movie Viva by Irish director Paddy Breathnach.
False Data Injection Attacks Against State Estimation in Power Distribution Systems (2018)

The existing research on false data injection (FDI) attacks against state estimation in transmission systems cannot be trivially extended to distribution feeders. The main reason is that a strong condition that requires the attacker to know the estimated state of distribution systems is needed, which makes the traditional FDI attacks difficult to be implemented in practice. In this paper, we propose a practical FDI attack model against state estimation in distribution systems, without paying expensive cost for obtaining the system state. We show that the attacker can approximate the system state based on power flow or injection measurements without too much effort. For local FDI attacks, the strong condition can be further relaxed to the knowledge of local state, which can be approximated based on a small number of power flow or injection measurements. Simulation results based on the IEEE test feeder demonstrate that the proposed practical FDI attack, even with the approximated system state, is more likely to compromise the state estimation without being detected, in comparison with the traditional attacks. This paper provides a basis to study the attack behaviors in distribution systems and a theoretical guide to develop protective countermeasures.

Organic Light-Emitting Diodes with Magnesium Doped CuPc as an Efficient Electron Injection Layer (2008)

Bright organic electroluminescent devices are developed using a metal-doped organic layer intervening between the cathode and the emitting layer. The typical device structure is a glass substrate/indium-tin oxide (ITO)/copper phthalocyanine(CuPc)/N,N-bis-(1-naphthl)-diphenyl-1,1'-biphenyl-4,4'-diamine (NPB)/Tris(8-quinolinolato) alu-minum(Alq3)/Mg-doped CuPc/Ag. At a driving voltage of 11 V, the device with a layer of Mg-doped CuPc (1:2 in weight) shows a brightness of 4312 cd/m2 and a current efficiency of 2.52 cd/A, while the reference device exhibits 514 cd/m2 and 1.25 cd/A.
Imaging and Alignment for Image-Guided Radiation Therapy (2007)

Image-guided radiation therapy is an exciting new area that focuses heavily on the potential benefit of advanced imaging and image registration to improve precision, thus limiting morbidity and potentially allowing for safe delivery of increased dose. This review explores the issues surrounding the use of imaging and image registration for treatment planning and verification, with emphasis on the underlying patient model and alignment algorithms.
Effect of undecanoic acid on phospholipid metabolismin<i>Trichophyton rubrum</i> (1982)

At its minimum inhibitory concentration, undecanoic acid (UDA) inhibits biosynthesis of phosphatidyl serine, phosphatidyl ethanolamine and polyphosphoinositol but does not inhibit the synthesis of phosphatidyl glycerol, phosphatidyl choline, phosphatidyl inositol and phosphatidic acid in Trichophyton rubrum. At higher concentration, however UDA inhibits biosynthesis of all phosphatides present in this dermatophyte. UDA also affects catabolism of these phosphatides. This inhibitory effect of UDA may be partially responsible for its toxic action on T. rubrum.
Symmetric light emitting devices from poly(<i>p</i>-di ethynylene phenylene) (<i>p</i>-di phenylene vinylene) derivatives (1995)

Light emitting devices were fabricated from 2,5-dialkoxy derivatives of poly(p-di ethynylene phenylene-p-di phenylene vinylene) (PDEPDPV) sandwiched between indium tin oxide (ITO) and Al. The current–voltage (I–V) curve, electroluminescence (EL) intensity-voltage (IEL–V) curve, and the EL spectra were identical in forward and reverse bias. The I–V curves were also symmetric under illumination, with I≊0 and V=0, suggesting a negligibly small internal electric field. At high bias voltage, carrier injection was found to be dominated by tunneling at the interfaces. At low bias voltage, tunneling among localized states at the Fermi level prevailed. The behavior is discussed in relation to Fermi-level pinning at defect states in the interfaces with the ITO and Al.
Symbol rate adaptation and blind rate detection using FOSSIL (forest for OVSF-sequence-set-inducing lineages) (2002)

We introduce a forest whose nodes represent orthogonal variable spreading factor (OVSF) code sequences of different lengths used for multi-rate CDMA. These code sequences have properties that facilitate symbol rate adaptation and blind rate detection, which can be used in a fast time-varying environment such as mobile communication systems. The properties of these codes also makes flexible the assignment of code sequences of different lengths to different users who communicates at different constant symbol rates. In particular, certain lineages in the forest have a property that the set of code sequences represented by such a lineage are cyclic orthogonal to each other with unit length being that of the shortest sequence in the set. We present the forest-structured generation of the code sequences and their properties. Then, we present a symbol rate adaptation protocol and a blind rate detection algorithm that use the code properties.
An improved map of conserved regulatory sites for <it>Saccharomyces cerevisiae</it> (2006)

Abstract Background The regulatory map of a genome consists of the binding sites for proteins that determine the transcription of nearby genes. An initial regulatory map for <it>S. cerevisiae </it>was recently published using six motif discovery programs to analyze genome-wide chromatin immunoprecipitation data for 203 transcription factors. The programs were used to identify sequence motifs that were likely to correspond to the DNA-binding specificity of the immunoprecipitated proteins. We report improved versions of two conservation-based motif discovery algorithms, PhyloCon and Converge. Using these programs, we create a refined regulatory map for <it>S. cerevisiae </it>by reanalyzing the same chromatin immunoprecipitation data. Results Applying the same conservative criteria that were applied in the original study, we find that PhyloCon and Converge each separately discover more known specificities than the combination of all six programs in the previous study. Combining the results of PhyloCon and Converge, we discover significant sequence motifs for 36 transcription factors that were previously missed. The new set of motifs identifies 636 more regulatory interactions than the previous one. The new network contains 28% more regulatory interactions among transcription factors, evidence of greater cross-talk between regulators. Conclusion Combining two complementary computational strategies for conservation-based motif discovery improves the ability to identify the specificity of transcriptional regulators from genome-wide chromatin immunoprecipitation data. The increased sensitivity of these methods significantly expands the map of yeast regulatory sites without the need to alter any of the thresholds for statistical significance. The new map of regulatory sites reveals a more elaborate and complex view of the yeast genetic regulatory network than was observed previously.

Word length study and architecture design of a K-best based MIMO-OFDM detector algorithm (2007)

The combination of multiple-input multiple-output (MIMO) and orthogonal frequency-division multiplexing (OFDM) has been adopted for high-data-rate transmission. A word length study and a top level architecture of a K-best based list sphere detector (LSD) algorithm for a MIMO-OFDM system are introduced in this paper. The word lengths were determined with computer simulations for 2 times 2 and 4 times 4 antenna systems with quadrature phase shift keying (QPSK), 16-quadrature amplitude modulation (QAM) and 64-QAM. The resulting word lengths can be used in the hardware implementation of the K-best LSD and they will lead to optimal floating point performance. The architecture was designed for a 2 times 2 antenna system with operating modes for QPSK and 16-QAM. Also a top level structure of a 4 times 4 MIMO detector is presented. The architecture allows the use of a variable list size.
Directional couplers using fluorinated polyimide waveguides (1998)

Optical properties of directional couplers using a fluorinated polyimide waveguide were demonstrated. At a wavelength of 1.3 /spl mu/m, directional couplers with the refractive index difference of 0.3% between the core and cladding have a maximum power coupling ratio of more than 97 and 96% for TE and TM polarisations, respectively. The excess loss for a 3-dB coupler was as low as 0.3 dB. Moreover, the change in the coupling ratio of the 3-dB couplers remained within 0.5% between 25 and 100/spl deg/C.
Liquid crystal/liquid-crystalline network composite systems Structure formation and electro-optic properties (1992)

Abstract The supermolecular structure and the electro-optic properties of a composite system consisting of a dense liquid-crystalline network and a low molar mass liquid crystal embedded in the network have been characterized. The composite systems were obtained by a photopolymerization of mixtures of a rigid mesogenic spacerless diacrylate and a low molar mass liquid crystal. They are characterized by a homogeneous distribution of the low molar mass liquid crystal in the network. The network has a cocontinuous periodic spinodal-type structure having a characteristic length scale of the order of 10 nm, if the low molar mass liquid crystal is removed or replaced by other solvents. The electro-optic switching properties are characterized by the fact that the active switching time and the width of the Frederiks transition are shifted to larger values as compared to those of the pure liquid-crystalline state. The decay times, on the other hand, are strongly reduced in the network.
A Scalable Optical Interconnection Network (2009)

With the rapid development of the high performance computer system, the high speed interconnection technology has become a hotspot of this field. Traditional electrical interconnection cannot meet the needs of the high speed data transmission. Therefore, optical interconnection technology was brought forward. Based on the study and analysis of the present optical interconnection networks, a new inter-processor optical interconnection fabric named PIBOS was put forward, which included the single-stage PIBOS and the multi-stage PIBOS. Simulation results showed that compared to other optical interconnection networks, the PIBOS interconnection network can reduce the packet latency and improve the throughput.

Biological activities of <i>Agave</i> by‐products and their possible applications in food and pharmaceuticals (2017)

Agave leaves are considered a by-product of alcoholic beverage production (tequila, mezcal and bacanora) because they are discarded during the production process, despite accounting for approximately 50% of the total plant weight. These by-products constitute a potential source of Agave extracts rich in bioactive compounds, such as saponins, phenolic compounds and terpenes, and possess different biological effects, as demonstrated by in vitro and in vivo tests (e.g. antimicrobial, antifungal, antioxidant, anti-inflammatory, antihypertensive, immunomodulatory, antiparasitic and anticancer activity). Despite their positive results in biological assays, Agave extracts have not been widely evaluated in food systems and pharmaceutical areas, and these fields represent a potential route to improve the usage of Agave plants as food additives and agents for treating medical diseases. © 2017 Society of Chemical Industry.
GEN05-1: SCA-based Reconfigurable Base Station System (2006)

It is expected that multiple radio access standards and systems will coexist in the same environment beyond 3G. Software defined radio (SDR) has made itself become a key enabling technology in order to realize such a flexible and reconfigurable radio system. Several research works have involved in the development of SDR systems and their efforts focus on hardware design and software framework. However, the current SDR system is insufficient to provide their full potential due to the performance problems. In this paper, we propose a reconfigurable base station system (RBS) which is composed of AdvancedTCA hardware platform and SCA-based software platform. Our RBS system shows that it is capable of changing mode between WiMAX and HSDPA. The application components of the RBS system divide into two parts, control data and traffic data components for the performance improvement. The traffic data components are implemented as adaptor components.
Colocalization and Interaction of Cyclooxygenase-2 with Caveolin-1 in Human Fibroblasts (2001)

Results from our previous study suggest that cyclooxygenase-2 (COX-2) induced by phorbol 12-myristate 13-acetate (PMA) may be localized to caveolae-like structures (Liou, J.-Y., Shyue, S.-K., Tsai, M.-J., Chung, C.-L., Chu, K.-Y., and Wu, K. K. (2000) J. Biol. Chem. 275, 15314-15320). In this study, we determined subcellular localization of COX-2 and caveolin-1 by confocal microscopy. COX-2 in human foreskin fibroblasts stimulated by PMA (100 nm) or interleukin-1beta (1 ng/ml) for 6 h was localized to plasma membrane in addition to endoplasmic reticulum and nuclear envelope. Caveolin-1 was localized to plasma membrane, and image overlay showed colocalization of COX-2 with caveolin-1. This was confirmed by the presence of COX-2 and caveolin-1 in the detergent-insoluble membrane fraction of cells stimulated by PMA. Immunoprecipitation showed complex formation of COX-2 with caveolin-1 in a time-dependent manner. A larger quantity of COX-2 was complexed with caveolin-1 in PMA-treated than in interleukin-1beta-treated cells. Purified COX-2 complexed with glutathione S-transferase-fused caveolin-1, which was not inhibited by the scaffolding domain peptide. Caveolin-1-bound COX-2 was catalytically active, and its activity was not inhibited by the scaffolding domain peptide. These results suggest that COX-2 induced by PMA and interleukin-1beta is colocalized with caveolin-1 in the segregated caveolae compartment. Because caveolae are rich in signaling molecules, this COX-2 compartment may play an important role in diverse pathophysiological processes.
Polymerization Kinetics and Nanostructure Evolution of Reactive Lyotropic Liquid Crystals with Different Reactive Group Position (2009)

The synthesis of polymers with inherent nanostructure has recently received much attention because of the wide range of potential application in which these materials could be used. To understand the factors that affect the nanoscopic order preservation upon polymerization, this work examines the influence of reactive group position in polymerizable surfactants that form reactive lyotropic liquid crystals (LLCs) on polymerization kinetics and order before and after polymerization. Less ordered LLC phases are formed with reactive surfactants bearing reactive groups in the nonpolar tail compared to reactive surfactants with reactive groups near the polar head. The polymerization kinetics are influenced by both the LLC order and the position of the reactive group. Higher polymerization rates are observed for reactive surfactants with the reactive group near the polar head with increasing surfactant concentration and LLC order. On the other hand, lower polymerization rates are observed for the reactive surfactant with the reactive group in the aliphatic tail at higher surfactant concentrations and LLC order. This behavior is mainly due to segregation of the reactive groups in different regions of the LLC phases as indicated by an apparent increase in both the propagation and termination kinetic constants. When using initiators that induce higher polymerization rates, greater LLC order preservation is observed after polymerization. Also, by using higher light intensities, the resulting polymer exhibits higher degrees of LLC order retention than that observed when polymerization is initiated with lower light intensities and corresponding lower polymerization rate.
Sagittal Abdominal Diameter Is an Independent Predictor of All-Cause and Cardiovascular Mortality in Incident Peritoneal Dialysis Patients (2013)

Backgrounds and Aims: Visceral fat has a crucial role in the development and progression of cardiovascular disease, the major cause of death in end-stage renal disease (ESRD). Although sagittal abdominal diameter (SAD), as an index of visceral fat, significantly correlated with mortality in the general population, the impact of SAD on clinical outcomes has never been explored in ESRD patients. Therefore, we sought to elucidate the prognostic value of SAD in incident peritoneal dialysis (PD) patients. Methods: We prospectively determined SAD by lateral abdominal X-ray at PD initiation, and evaluated the association of SAD with all-cause and cardiovascular mortality in 418 incident PD patients. Results: The mean SAD was 24.564.3 cm, and during a mean follow-up of 39.4 months, 97 patients (23.2%) died, and 49.4% of them died due to cardiovascular disease. SAD was a significant independent predictor of all-cause [3rd versus 1st tertile,
Characterization of a new variant DNA (cytosine‐5)‐methyltransferase unable to methylate double stranded DNA isolated from the marine annelid worm <i>Chaetopterus variopedatus</i> (1999)

The enzyme S‐adenosylmethionine‐DNA (cytosine‐5)‐methyltransferase has been identified, first time for invertebrates, in embryos of the marine polychaete annelid worm Chaetopterus variopedatus . The molecule has been isolated from embryos at 15 h of development. It is a single peptide of about 200 kDa molecular weight, cross‐reacting with antibodies against sea urchin DNA methyltransferase. The enzymatic properties of the molecule are similar to those of Dnmt1 methyltransferases isolated from other organisms, but with the peculiarity to be unable to make ‘de novo’ methylation on double stranded DNA.
