Experiences With the First Japanese-Made Solid-Oxide Fuel-Cell System (2005)

A solid-oxide fuel-cell (SOFC) system based on planar type cells and a cylindrical stack design was examined for small-scale stationary applications. To reduce the operating temperature of electrolyte-supported type cells, scandia-stabilized zirconia (ScSZ) was employed as the electrolyte. A compact catalytic partial oxidation (CPOx) reformer was employed and thin ferritic stainless steel was used for the interconnect bipolar plates. As a result, a carefully designed internal manifold-type 68 cell stack produced an output of 1kW at 1073K with thermal self-sustaining conditions. Also, important issues in realizing high-efficiency, cost-effective SOFC systems are discussed.

Heat pipes cool probe and sandwich panel (1981)

Two concepts integrate heat-pipe technology. Probe with heat-pipe cooled jacket is self-contained, passive, and has no moving parts, unlike conventional air and water cooled probes. It is used in hostile, high temperature environments like wind tunnels and powerplants or on high-speed research and hypersonic cruise vehicles. Heat-pipe sandwich panel combines structural efficiency of sandwich with thermal efficiency of heat-pipe. It is used to eliminate thermal gradients and stresses, minimize thermal distortions, and transfer heat from one face of panel to other.
Investigation of the self-absorption effect using spatially resolved laser-induced breakdown spectroscopy (2016)

This study discovered the distributional difference of self-absorption effect in laser-induced breakdown spectroscopy, and investigated the method to reduce the self-absorption effect.
Squeezable electron tunneling junctions (1983)

We report a versatile new technique for constructing electron tunneling junctions with mechanically adjusted artificial barriers. I-V curves are presented for tunneling between Ag electrodes with vacuum, gas, liquid, or solid in the barrier. An energy gap is apparent in the measured I-V curve when tunneling occurs between superconducting Pb electrodes.
Continuous wave operation of 1.3 μm vertical cavity InGaAsN quantum well lasers (2005)

Vertical-cavity lasers emitting at 1.3 /spl mu/m are extremely attractive for high bandwidth fiber communications where it is advantageous to operate at the dispersion minimum of silica optical fiber. To date, VCSELs based on pseudomorphic GaAs materials have achieved lasing emission only slightly longer than 1.3 /spl mu/m. We report the first 1.3 /spl mu/m selectively oxidized VCSELs using InGaAsN quantum wells which operate at continuous wave at and above room temperature.
Fast Gas Sensing Using an Integrated Synthetic Jet Actuator (2006)

A miniature (millimeter-scale) synthetic jet actuator is integrated with a chemical gas sensor (chemFET) to effect inhalation and exhalation of ambient gas samples and induce small-scale mixing at the surface of the sensor. The fluidically integrated jet transports ambient fluid into the jet/sensor assembly through integrated fluid channels, impinges the sample fluid on the sensing element, and finally ejects the sample fluid to the ambient. The response of the sensor in the presence of the active jet is compared to its response when the jet is inactive. The jet actuator directs entrained ambient air toward the active surface of the sensor, and the impingement of sample gas onto the surface of the sensor results in faster response time. Because the operating characteristics of the integrated synthetic jet actuator can be easily optimized for specific configurations, it is concluded that jet-assisted sampling and sample transport coupled with turbulent impingement can offer significant advantages for gas sensor systems
Industrial-grade anti-reflection coatings with extreme scratch resistance (2019)

Anti-reflection coatings are widely used throughout the field of optical technology such as in corrective eyeglasses, camera lenses, and microscope optics, to improve the transmittance and reduce the reflectance of glass and other transparent materials. To date, these coatings have suffered from relatively poor scratch resistance and high scratch visibility compared to standard glasses. This has limited their use in applications requiring high mechanical durability such as on the chemically strengthened glasses widely used in modern touch screen devices. Here extremely scratch-resistant anti-reflection coatings are fabricated using industrially scalable reactive sputtering processes. These coatings provide a combination of surface reflectance below 0.7%, low color shifts, nanoindentation hardness as high as 18 GPa, and levels of scratch resistance which dramatically exceed commercial chemically strengthened glasses. An interdisciplinary opto-mechanical design approach has enabled a significant paradigm shift in the use of high-precision optical coatings for mechanically demanding applications. As a direct outcome of the work reported in this Letter, similar coating designs have been successfully deployed on millions of consumer electronics devices with very robust field performance.
Online Human Action Detection using Joint Classification-Regression Recurrent Neural Networks (2016)

Human action recognition from well-segmented 3D skeleton data has been intensively studied and has been attracting an increasing attention. Online action detection goes one step further and is more challenging, which identifies the action type and localizes the action positions on the fly from the untrimmed stream data. In this paper, we study the problem of online action detection from streaming skeleton data. We propose a multi-task end-to-end Joint Classification-Regression Recurrent Neural Network to better explore the action type and temporal localization information. By employing a joint classification and regression optimization objective, this network is capable of automatically localizing the start and end points of actions more accurately. Specifically, by leveraging the merits of the deep Long Short-Term Memory (LSTM) subnetwork, the proposed model automatically captures the complex long-range temporal dynamics, which naturally avoids the typical sliding window design and thus ensures high computational efficiency. Furthermore, the subtask of regression optimization provides the ability to forecast the action prior to its occurrence. To evaluate our proposed model, we build a large streaming video dataset with annotations. Experimental results on our dataset and the public G3D dataset both demonstrate very promising performance of our scheme.
Magnetic ionic liquids as PCR-compatible solvents for DNA extraction from biological samples (2015)

A polymerase chain reaction (PCR) buffer was systematically designed to relieve the inhibition caused by hydrophobic magnetic ionic liquids (MILs). We describe a simple, rapid method for MIL-based plasmid DNA extraction from crude bacterial cell lysate in which DNA-enriched MIL is transferred directly to a PCR tube for analysis.
Constrained least-squares spectral analysis: Application to seismic data (2012)

ABSTRACT An inversion-based algorithm for computing the time-frequency analysis of reflection seismograms using constrained least-squares spectral analysis is formulated and applied to modeled seismic waveforms and real seismic data. The Fourier series coefficients are computed as a function of time directly by inverting a basis of truncated sinusoidal kernels for a moving time window. The method resulted in spectra that have reduced window smearing for a given window length relative to the discrete Fourier transform irrespective of window shape, and a time-frequency analysis with a combination of time and frequency resolution that is superior to the short time Fourier transform and the continuous wavelet transform. The reduction in spectral smoothing enables better determination of the spectral characteristics of interfering reflections within a short window. The degree of resolution improvement relative to the short time Fourier transform increases as window length decreases. As compared with the continuous wavelet transform, the method has greatly improved temporal resolution, particularly at low frequencies.
ENHANCED PROXIMITY WARNING SYSTEM (EPWS) FOR LOCOMOTIVES (1997)

The Enhanced Proximity Warning System (EPWS) allows location information to be exchanged between trains using track ID and milepost references as opposed to latitude/longitude without the need for any track or ground infrastructure additions. An on-board track database also allows implementation of a number of safety functions which are not dependent on radio data communications between trains. Use of Global Positioning System (GPS) satellites is a key part of the navigation system and is supplemented by other sensors to permit more accurate location and track determination. Direct locomotive-to-locomotive data communications are based on shared use of one of the end-of-train (EOT) monitor system frequencies. EOT operation is still protected as the primary user of the channel. This communications link allows exchange of location references, speed, and direction information between trains. A computer in each locomotive can then compute the distance and relative direction of other trains and warn the engineer of potential conflicts.
Development of a portable therapeutic and high intensity ultrasound system for military, medical, and research use (2008)

We have developed a portable high power ultrasound system with a very low output impedance amplifier circuit (less than 0.3 Omega) that can transfer more than 90% of the energy from a battery supply to the ultrasound transducer. The system can deliver therapeutic acoustical energy waves at lower voltages than those in conventional ultrasound systems because energy losses owing to a mismatched impedance are eliminated. The system can produce acoustic power outputs over the therapeutic range (greater then 50 W) from a PZT-4, 1.54 MHz, and 0.75 in diameter piezoelectric ceramic. It is lightweight, portable, and powered by a rechargeable battery. The portable therapeutic ultrasound unit has the potential to replace "plug-in" medical systems and rf amplifiers used in research. The system is capable of field service on its internal battery, making it especially useful for military, ambulatory, and remote medical applications.
Site-specific relative risks of second primary malignancies among patients with Waldenstrom macroglobulinemia. (2011)

e18566 Background: Waldenstrom Macroglobulinemia (WM) is a rare and indolent B-cell malignancy characterized by overproduction of monoclonal immunoglobulin M protein. The long duration of survival for most patients with WM and the use of potentially carcinogenic agents during therapy raise concerns about the development of second primary malignancies. However, the relative risks of second primary malignancies among patients with WM are not well-documented. Therefore, we investigated site-specific relative risks of second primary malignancies among patients with primary WM. Methods: Data from 9 population-based registries of the Surveillance, Epidemiology, and End Results program were used to identify patients diagnosed with primary WM between 1973 and 2007 for whom follow-up data were available. Standardized incidence ratios (SIRs) with corresponding 95% confidence intervals (CIs) of site-specific second primary malignancies were estimated by dividing the number of observed cases of second primary malignancies for the specific site within the WM cohort by the number of expected cases (standardized by age, sex, race/ethnicity, and calendar-year) of secondary primary malignancies for the specific site in the general United States population. Results: The WM cohort (n=1,521) yielded 226 second primary malignancies during 6,958 person-years of follow-up (incidence density = 3,248 cases/100,000 person-years of follow-up). Potentially durable estimates of higher site-specific relative risks were observed for colon (SIR=2.3, 95% CI: 1.6, 3.3), lung (SIR=1.7, 95% CI: 1.2, 2.4), non-Hodgkin lymphoma (SIR=4.9, 95% CI: 3.2, 7.1), myeloma (SIR=4.9, 95% CI: 2.2, 9.2), and acute myeloid leukemia (SIR=5.9, 95% CI: 2.2, 12.8) compared to the general US population. Conclusions: Our results indicate that patients with WM have a higher relative risk of second primary malignancies for several sites. Although the higher relative risks of second primary hematologic malignancies may be treatment- or immunologically-related, the modestly higher relative risks of second primary solid tumors may be the result of detection bias or risk factors shared between WM and the specific solid tumors.
Abstract A006: Frameshift peptide neoantigens as vaccine targets in microsatellite-unstable cancers (2016)

Abstract Background: Deficient DNA mismatch repair (MMR) boosts the accumulation of frameshift mutations in genes encompassing coding microsatellites (cMS). This results in translation of proteins with mutation-induced frameshift peptide (FSP) neoantigens rendering MMR-deficient microsatellite-unstable (MSI) cancers highly immunogenic. Patients with MSI cancers and healthy individuals affected by Lynch syndrome, an inherited prediposition for MSI cancers, develop specific immune responses against these neoantigens. MSI cancers are unique in tumor immunology, because they express a defined set of long neoantigens that result from functionally relevant driver mutations and therefore are shared by the majority of MSI cancers. Consequently, MSI cancers in Lynch syndrome are an ideal model to evaluate the concept of cancer vaccines, which, with the increasing knowledge about mutational antigens in a wide variety of cancer types, can potentially be applied to many human cancer types. We here report the results of a clinical phase I/IIa trial as the first step to translate this concept into the clinical application. Methods: The vaccination protocol comprised 3 cycles of 4 subcutaneous applications of FSP antigens (frameshift variants of the coding microsatellite-containing genes AIM2, HT001, TAF1B) mixed with Montanide ISA-51 VG over a 6 month period. Inclusion criteria were history of MSI-H colorectal cancer (UICC stage III or IV) and completion of standard chemotherapy. Phase I of the trial evaluated safety and toxicity as the primary endpoint (6 patients), phase IIa addressed the induction of cellular and humoral immune responses (16 patients). Results: Significant induction of FSP-specific immune responses against one or more FSP antigens was observed in all patients vaccinated per protocol. No vaccination-induced systematic severe adverse events occurred. Few patients had stage IV disease and were evaluable according to RECIST. One heavily pretreated patient with bulky metastases showed a stable disease and stable CEA levels over 7 months under the study treatment. Conclusions: Vaccination with FSPs is well tolerated and leads to the induction of humoral and cellular immune responses. FSP vaccination represents a promising novel approach for treatment of MSI cancer patients and for tumor prevention in Lynch syndrome, allowing the evaluation of the concept of preventive cancer vaccines in an ideal model scenario of a defined high-risk patient population.

Simultaneous Analysis of Hop Bittering Components by High-Performance Liquid Chromatography. II. Evaluation of Hop Deterioration (1987)

A rapid high-performance liquid chromatography (HPLC) procedure for simultaneous separation and quantitation of the main nine hop bittering components, i.e., three analogs of iso-α-, α-, and β-acids in hops and beer, has also been successfully applied to determine the relative amounts of some components formed during hop storage. These components were eluted in fractions that we designated “S-fractions” in the HPLC profile. When hop pellets were stored in the presence or absence of air at various temperatures from −5 to 50° C, a linear correlation between the increase in S-fractions and the decrease in α- and β-acids was obtained. Based on this correlation, we can estimate from the amount of S-fractions in hops not only the losses of α- and β-acids during storage, but also the initial level of α- and β-acids in hops. The ultraviolet spectrum of each peak in the eluant during HPLC analysis suggests that the major components of S-fractions are tricyclodehydroisohumulones, hulupones, or humulinic acids. Thus, these components were considered to be formed at the expense of α- and β-acids during storage. From brewing trials with strongly deteriorated hops, the bittering and aromatic effects of S-fractions on beer quality were demonstrated by chemical and sensory analyses.
Wavelet–k Nearest Neighbor Vehicle Classification Approach with Inductive Loop Signatures (2013)

In this study, a new vehicle classification algorithm was developed with inductive loop signature technology. There were two steps to the proposed algorithm. The first step was to use the Haar wavelet to transform and reconstruct inductive vehicle signatures, and the second step was to group vehicles into FHWA vehicle types through the use of the k nearest neighbor (KNN) approach with a Euclidean distance classifier. To determine the proper proportion of the wavelet to apply for reconstruction and feature extraction, transformed signatures were examined with percentages of large components of their corresponding wavelets. To implement the KNN approach, a library of vehicle signature templates for each FHWA vehicle class was composed. The proposed vehicle classification algorithm demonstrated promising classification results, with a 92.4% overall accuracy. The algorithm can be applied to the real world without the concerns about recalibration and transferability that arise with the use of signature data from single loops. Two additional vehicle classification schemes were applied for performance evaluation. For the inductive signature performance evaluation classification scheme, which aimed to facilitate emission analysis and easy interpretation, the overall accuracy was 94.1%. For the axle-based vehicle classification scheme proposed in this project, which aimed to group vehicles by use and the number of axles, the overall accuracy was 93.8%. Future research will focus on refinement of the signature template library for each FHWA vehicle type to further improve the performance of the proposed vehicle classification algorithm. The selection of the value of k for the KNN approach will be investigated also.
<title>Optimization of low-coherence interferometry for quantitative analysis of tissue optical properties</title> (2002)

Noninvasive monitoring of analytes can be performed with optical coherence tomography (OCT) technique. This technique may allow measurement of optical properties of tissue (attenuation, scattering, optical thickness, etc.) that may be dependent on analyte concentration. Accurate monitoring of analyte concentration requires measurement of the optical properties with high accuracy. The accuracy of measurements depends on OCT technical characteristics and the level of speckle noise. In this paper, we report the results of the calibration of OCT system sensitivity for absolute and relative measurements of the backscattering and total attenuation coefficients in scattering standard, tissue phantoms (suspensions of polystyrene microspheres in water solutions of glucose), and human skin. We measured the OCT sensitivity as a function of depth and used this dependence for correction of signals. The amplitude and spatial period of backscattered signal modulation resulted from speckle noise were measured for the scattering standard and human skin. The dependence of speckle and electronic noise on the range of spatial and temporal averaging of OCT signals was determined. Our studies show that the accuracy of measurement of changes in optical properties of tissue with OCT technique can be significantly improved by reducing of speckle noise and by using the signal correction algorithm.
ELECTRET ION CHAMBER METHOD FOR CONTINUOUS MEASUREMENT OF CONCENTRATION OF RADON IN WATER (1993)

The use of an electret ion chamber for measuring dissolved radon in water sample has been described in a recent publication (Health Physics 6: 397-405; 1993). The current work is a further development of electret ion chamber technology for continuous measurement of dissolved radon in water. A steady concentration of radon in water is generated by bubbling radon gas through a jar of water and maintaining a constant rate of feed and bleed of water. The outgoing water flows into a 4 L cylindrical chamber. Air bubbled at 1 Llmin through a 10 cm long sintered stainless steel immersed in this water releases radon from water into the chamber volume. A I L electret ion chamber (H-chamber) loaded with an electret is hung in the 4 L chamber. Radon diffuses into the H-chamber through its tyvek (carbon coated) covered openings. The radon concentration in air is measured from the change in electret voltage. The concentration of radon in water is then obtained from the concentration of radon in air and the air and water flow rates. The radon concentration in water is also measured by the standard liquid scintillation counting method. For the concentration range covered (4.7 to 88 BqIL) there is a good agreement between the two methods.
An Advanced NAND-Structure Cell Technology for Reliable 3.3 V 64 Mb Electrically Erasable and Programmable Read Only Memories (EEPROMs) (1994)

An extremely small NAND-structure cell of 1.13 µm 2 per bit, 80% of the smallest Flash memory cell reported so far [H. Kume et al. : IEEE Tech. Dig. IEDM (1992) p. 991], has been developed in 0.4 µm technology. The chip size of a 64 Mb NAND electrically erasable and programmable read only memory (EEPROM) using this cell is estimated to be 120 mm 2 , which is 60% that of a 64 Mb DRAM. In order to realize the small cell size, a 0.8 µm field isolation is used. A negative bias of -0.5 V to the P-well of the memory cell is applied during writing. In addition, a bit-by-bit intelligent writing technology allows a 3.3 V data sensing scheme which can suppress read disturb to 1/1000 in comparison with the conventional 5 V scheme. As a result, it is expected that with this technology, 10 6 write and erase cycles can be achieved and that the tunnel oxide can be scaled down from 10 nm to 8 nm.
