Axisymmetric analysis and experimental measurements of magnetic field in the end region of a turbine generator (1983)

This paper presents a method of analysis of the leakage magnetic field caused by the stator and rotor end windings of a turbine generator under no load and under load conditions, using a bidimensional finite element program. Also, we report measurement methods and data processing techniques for the tests carried out on a 370 MVA turbine generator in order to confirm the above numerical analysis. The theoretical and experimental results, correlated to various machine operating conditions are compared. The dependence of the axial flux density on the end teeth of the stator in terms of the generator power factor is shown.
Effect of magnetostriction on remanent magnetization (1985)

Magnetostriction effects of remanent magnetization are examined in a phenomenological model that is used to design a high magnetization polycrystalline spinel ferrite with excellent square hysteresis loop properties. Isotropic magnetostriction is compensated by substituting Mn(3+) ions for 0.2 Fe(3+) ions per formula unit of Ni.65Zn.35Fe2O4 host material. As predicted by theory, the magnetostriction reduction dramatically increases the remanent magnetization and removes most of its external stress sensitivity. The resulting remanent magnetization, which approaches 4000 G, represents an increase of more than a factor of 2 over that of the host composition, with no significant deterioration in other magnetic nd dielectric properties. The remanence ratio improvement is in general accord with estimates predicted by the theoretical model. Keywords: Remanent magnetization increase; Magnetostriction compensation; Stress demagnetization; Square hysteresis loop NiZn ferrite; High magnetization/low coercivity ferrite.
Evaluation of Enriched Cyberspace for Adaptive Support of Remote Collaboration (2010)

Due to the geographical distribution, different cognitive capacity, and different domain competency of workers or learners, many misunderstandings can occur during distributed remote collaboration, leading to inefficient discussions and undesired results. To make remote collaboration more efficient and dependable, enriching cyberspace through adaptively utilizing is proposed and evaluated. This assesses situations of remote users through information fusion of multiple biological sensors and the related contexts such as user profiles. Transmitting and using such information, the system adaptively supports the distributed remote collaboration by stressing, warning, and presenting keywords/summaries in multimedia. Effects of presenting keywords/summaries adaptively depending on situations are evaluated as to the decrease of not-/misunderstanding possibilities during the explanation on the Cyberspace. Moreover, the adaptive selection effects of keywords or summaries presentation depending on cognitive profiles of remote members are also evaluated. These evaluations demonstrate the feasibility and usefulness of the proposed method.
Heterointerface Engineering of β-Chitin/Carbon Nano-Onions/Ni–P Composites with Boosted Maxwell-Wagner-Sillars Effect for Highly Efficient Electromagnetic Wave Response and Thermal Management (2022)

The rational construction of microstructure and composition with enhanced Maxwell-Wagner-Sillars effect (MWSE) is still a challenging direction for reinforcing electromagnetic wave (EMW) absorption performance, and the related EMW attenuation mechanism has rarely been elucidated. Herein, MWSE boosted β-chitin/carbon nano-onions/Ni-P composites is prepared according to the heterointerface engineering strategy via facile layer-by-layer electrostatic assembly and electroless plating techniques. The heterogeneous interface is reinforced from the aspect of porous skeleton, nanomaterials and multilayer construction. The composites exhibit competitive EMW response mechanism between the conductive loss and the polarization/magnetic loss, as describing like the story of "The Hare and the Tortoise". As a result, the composites not only achieve a minimum reflection loss (RL<sub>min</sub>) of - 50.83 dB and an effective bandwidth of 6.8 GHz, but also present remarkable EMW interference shielding effectiveness of 66.66 dB. In addition, diverse functions such as good thermal insulation, infrared shielding and photothermal performance were also achieved in the hybrid composites as a result of intrinsic morphology and chemicophysics properties. Therefore, we believe that the boosted MWSE open up a novel orientation toward developing multifunctional composites with high-efficient EMW response and thermal management.
A robust measure of probability density function of various noises in electromyography (EMG) signal acquisition (2015)

Statistical methods for estimating a probability density function (PDF) of surface electromyography (EMG) signals during upper-limb motions have been investigated in previous studies to select the suitable feature extraction methods for multifunction myoelectric control systems. While these methods have achieved a good performance in estimating PDF of EMG signals from different motions and muscles, no prior studies have evaluated the performance of these methods to estimate the PDF of noises in EMG signal acquisition. The utility of these methods consisting of bicoherence, kurtosis, negentropy, and L-kurtosis, was investigated in estimating the PDF of five different noise types: the single and many spurious background spikes, white Gaussian noise, motion artifact, and power line interference. The results show that the L-kurtosis can identify the PDF of all studied noises in EMG signal acquisition correctly. In contrast, other estimating methods are inaccuracy in at least one noise type.
Joint and individual analysis of breast cancer histologic images and genomic covariates (2021)

The two main approaches in the study of breast cancer are histopathology (analyzing visual characteristics of tumors) and genomics. While both histopathology and genomics are fundamental to cancer research, the connections between these fields have been relatively superficial. We bridge this gap by investigating the Carolina Breast Cancer Study through the development of an integrative, exploratory analysis framework. Our analysis gives insights - some known, some novel - that are engaging to both pathologists and geneticists. Our analysis framework is based on Angle-based Joint and Individual Variation Explained (AJIVE) for statistical data integration and exploits Convolutional Neural Networks (CNNs) as a powerful, automatic method for image feature extraction. CNNs raise interpretability issues that we address by developing novel methods to explore visual modes of variation captured by statistical algorithms (e.g. PCA or AJIVE) applied to CNN features.
Long-term results of various surgical treatments for cholesteatoma. (1990)

The authors have studied 11 series of results following cholesteatoma surgery by closed or open technique. The closed technique was performed in 77%. The notion of surgical revision is not accepted by all surgeons; it is practised with an average of 59% for the whole series. Residual cholesteatoma and/or recurrences are observed in 34% of the cases of which 20% have been discovered at the time of revision surgery. Surgical revision appears mandatory to the authors.
Identification of Hydrolyzed Inulin Syrup and High-Fructose Corn Syrup in Apple Juice by Capillary Gas Chromatography PVM 4:1999 (2001)

A peer-verified, gas chromatographic (GC) method is presented for the identification of hydrolyzed inulin syrup (HIS) and high-fructose corn syrup (HFCS) in apple juice. The procedure involves determining the Brix value of the apple juice or apple juice concentrate and preparing a dilution of the test sample to 5.5 degrees Brix. A 100 microL aliquot of the 5.5 degrees Brix test solution is then freeze-dried in a GC autosampler vial. The sugars in the freeze-dried residue are converted to trimethylsilyl derivatives, by the addition of an appropriate silylation reagent, and the vial is heated at 75 degrees C for 30 min. After derivatization, the solution is introduced into a gas chromatograph where the analytes are separated on a 30 m, 0.25 mm id DB-5 column. The method can use hydrogen, helium, or nitrogen as the carrier gas. The analytes and marker compounds are measured by use of a flame ionization detecone of the 2 syrups at 2 levels. Dilution was ascertained by the presence of retrograde sugar markers found in the 2 sugar syrups. All 3 laboratories involved in the study were able to identify the correct diluent in the blind, randomly coded, apple juice test portions. The levels of dilution in the test portions were 0, 6.9% (HIS), 16.0% (HIS), 8.1% (HFCS), and 17.0% (HFCS). No false positive results were reported. Quantitative conclusions can be drawn when the same syrup is used for dilution and as a reference standard.

Studies on the Oxy-acid Phosphors. IV. Application of Polarography to the Analysis of Activators, Especially, in Calcium Silicate Phosphors (1955)

Abstract The amount of activators, which are now used for the present phosphors, was determined by means of polarography. The results obtained shows that manganese or copper is not dissipated during firing, while antimony or lead is dissipated in that period. As for calcium silicate phosphors activated by manganese and lead, the residual amounts of activators were analysed by polarography and, these amount being taken as the additional factorial effects, the analysis of covariance was carried out to see the effects of atmosphere and firing time on the brightness. The results obtained show that the amount of lead has a more significant effect upon the brightness than manganese and the change of atmosphere causes that of the amount of activators and the brightness.
Thermal-aware scratchpad memory design and allocation (2010)

Scratchpad memories (SPMs) have become a promising on-chip storage solution for embedded systems from an energy, performance and predictability perspective. The thermal behavior of these types of memories has not been considered in detail. This thermal behavior plays an important role in the reliability of silicon devices and in their static (leakage) power consumption. In this paper, we propose two different techniques to improve the thermal behavior of SPMs. First, we propose a hardware-based, thermal-aware address translation technique that physically distributes memory accesses to consecutive addresses evenly over the whole memory area. Second, we propose a software-based, thermal-aware address generation technique. This technique tries to distribute the variables that are allocated to the SPM in such a way that an even thermal distribution is achieved. The first technique works particularly well for applications with a regular access pattern, whereas the second technique can also improve the behavior of applications with irregular access patterns. The two techniques thus complement each other and work well together. Using the first technique we show that the peak temperature of an SPM in 65nm technology, when running a typical streaming application, is decreased by up-to 10.0°C. Temperature cycling is reduced from up-to 14.8°C to almost zero in comparison with a non-thermal-aware solution. For our benchmark applications with an irregular access pattern, the second technique is able to reduce the peak temperature by up-to 3.5°C. These savings for both techniques are obtained without any performance degradation or extra silicon area.
Antiphase complex-coupled surface-emitting distributed feedback diode lasers with absorptive gratings (1998)

Theoretical analysis of antiphase-type complex-coupled, surface-emitting distributed feedback (CC-SE-DFB) diode lasers with absorptive gratings is presented and discussed. Two different designs are studied: one utilizing a semiconductor-based second-order loss and index grating placed at the metal-semiconductor (p-side) interface, and the other employing a combination of metallic and semiconductor materials for the second-order loss and index grating. For certain design parameters, these two types of absorptive-grating structure are shown to select lasing in the symmetric mode (i.e., orthonormal emission in a single-lobe beam pattern). By comparison to metal-grating surface-emitting devices, the threshold gains for these structures are lower by factor of 3 to 4. For 500-μm-long gratings, the symmetric-mode is favored to lase with threshold gain values as low as 18 cm/sup -1/ and differential quantum efficiency as high as 34%.
The European Community as a Learning System (1986)

In Western Europe at least, during the 1940s and 1950s welfare states became an established part of the political order. The rights they conferred to social protection and educational opportunity combined with rising standards of living and full employment to produce what now, in retrospect, seems a golden age of social harmony and economic prosperity.
Zero-field electron magnetic resonance spectra of copper carboxylates (1997)

The design of a new zero-field electron magnetic resonance spectrometer including cryogenic capabilities and a new tuning mechanism for sweeping over approximately two octaves is described. The tuning mechanism is based on a one-loop, two-gap resonator mounted on quartz rods in such a manner that rotating the rods changes the width of the gap and the resonant frequency of the resonator. The spectrometer was used to measure the zero-field emr spectra of several copper carboxylate dimers at 90 K and 70 K. The parallel hyperfine structure was well resolved in all of the spectra and this allowed accurate determination of D, E, and A‖. A⊥ was found to be poorly defined in general and least square refinements attached large errors to this term in the spin Hamiltonian. The zero-field terms in the spin Hamiltonian at 90 K were determined to be D=9.828 GHz, E=83 MHz, A‖=217 MHz for [Cu(CH3CO2)2(CO(NH2)2)]2⋅2H2O; D=9.985 GHz, E=43 MHz, A‖=221 MHz for [Cu(C2H5CO2)2(H2O)]2; D=10.107 GHz, E=49 MHz, A‖=218 MHz for [Cu(C2H5CO2)2(CO(NH2)2)]2; D=9.979 GHz, E=192 MHz, A‖=223 MHz for [Cu(C6H5CO2)2(C6H5CO2H)]2. A model which assumes A⊥=0 is discussed in detail as it was found that all of the features observed in the spectra could be interpreted using simple explicit expressions derived from the model.

Dual-function triazole–pyridine derivatives as inhibitors of metal-induced amyloid-β aggregation (2012)

Dysregulated metal ions are hypothesized to play a role in the aggregation of the amyloid-β (Aβ) peptide, leading to Alzheimer's disease (AD) pathology. In addition to direct effects on Aβ aggregation, both Cu and Fe can catalyze the generation of reactive oxygen species (ROS), possibly contributing to significant neuronal toxicity. Therefore, disruption of metal-Aβ interactions has become a viable strategy for AD therapeutic development. Herein, we report a new series of dual-function triazole-pyridine ligands [4-(2-(4-(pyridin-2-yl)-1H-1,2,3-triazol-1-yl)ethyl)morpholine (L1), 3-(4-(pyridin-2-yl)-1H-1,2,3-triazol-1-yl)propan-1-ol (L2), 2-(4-(pyridin-2-yl)-1H-1,2,3-triazol-1-yl)acetic acid (L3), and 5-(4-(pyridin-2-yl)-1H-1,2,3-triazol-1-yl)pentan-1-amine (L4)] that interact with the Aβ peptide and modulate its aggregation in vitro. Metal chelation and Aβ interaction properties of these molecules were studied by UV-vis, NMR spectroscopy and X-ray crystallography. In addition, turbidity and transmission electron microscopy (TEM) were employed to determine the anti-aggregation properties of L1-L4. All compounds demonstrated an ability to limit metal-induced Aβ aggregation. Overall, our studies suggest the utility of the triazole-pyridine framework in the development of chemical reagents toward inhibitors for metal-triggered Aβ aggregation.
Ferroelectric Thin Films in Fluidic Environments: A New Interface for Sensing and Manipulation of Matter (2011)

For decades ferroelectric thin films (FETFs) have been the focus of research and development for next-generation memory and semiconductor devices. FETFs are attractive because their polarization states are highly localized, stable, and switchable. These unique properties are also attractive for (bio)molecular sensing and separation applications. Polarization of both polymer and ceramic FETF results in the expression of a sustained high, non-Faradaic, surface charge density. If these surface charges are maintained in aqueous environments, then the resulting electrostatic forces should induce the formation of electrolyte gradients and aid in the localization of charged species to the surface. Recently, there has been a growing interest in the interfacial properties of FETFs, specifically how they interact with liquid or gaseous phases. Recent work has shown that the FETF polarization state affects adsorption from the gaseous phase, surface catalysis, and cell growth. Encouraged by these findings, the use of FETFs in aqueous environments is explored. After an introduction to FETFs, the growing body of literature on the FETF interface is reviewed, along with the limited number of studies demonstrating FETF function in gas and liquid environments. Finally, the exciting possibilities that FETFs could bring to interfacial engineering and lab-on-chip (LOC) device design is reviewed.
Online Scheduling Switch for Maintaining Data Freshness in Flexible Real-Time Systems (2009)

Maintaining the temporal validity of real-time data is one of the crucial issues in a real-time database system. Past studies focus on designing algorithms to minimize imposed workload by a fixed set of update transactions while maintaining data freshness within validity intervals. In this paper we revisit this problem by investigating the cost of data freshness maintenance and online scheduling overhead in the presence of mode changes in real-time systems. We propose to apply periodic scheduling policies when the imposed update workload is low to maintain high data freshness. When the update workload becomes high, we propose to switch to more sophisticated algorithms to improve schedulability. In the latter case, not only each scheduling policy must be able to schedule the task set in the corresponding mode, temporal validity must also be maintained during the mode changes. To address this problem, two algorithms, named search-based switch (SBS) and adjustment-based switch (ABS) are proposed to search for the proper switch point online. SBS checks the temporal validity at the beginning time slot of each idle period while ABS further relaxes this restriction through schedule adjustment. Our experimental results demonstrate the correctness and efficiency of these two algorithms. Our results also show that scheduling switch according to the runtime processor workload can significantly outperform a single fixed scheduling policy in terms of data freshness while incurring only limited online switch overhead.
Dynamic-Droplet-Model Interpretation of Light-Scattering Experiments on Critical Fluids (1975)

Near the critical point of a fluid or fluid mixture, we postulate the existence of a size distribution of diffuse droplets or clusters of molecules. This distribution is combined with the Rayleigh-Debye scattering approximation and the theory of Brownian motion to describe the observed behavior of the intensity and the autocorrelation of light scattered by critical fluids.

Does the Whole Exceed its Parts? The Effect of AI Explanations on\n Complementary Team Performance (2020)

Many researchers motivate explainable AI with studies showing that human-AI\nteam performance on decision-making tasks improves when the AI explains its\nrecommendations. However, prior studies observed improvements from explanations\nonly when the AI, alone, outperformed both the human and the best team. Can\nexplanations help lead to complementary performance, where team accuracy is\nhigher than either the human or the AI working solo? We conduct mixed-method\nuser studies on three datasets, where an AI with accuracy comparable to humans\nhelps participants solve a task (explaining itself in some conditions). While\nwe observed complementary improvements from AI augmentation, they were not\nincreased by explanations. Rather, explanations increased the chance that\nhumans will accept the AI's recommendation, regardless of its correctness. Our\nresult poses new challenges for human-centered AI: Can we develop explanatory\napproaches that encourage appropriate trust in AI, and therefore help generate\n(or improve) complementary performance?\n
