Demonstration of an Interferometric Laser Ranging System for a Follow-On Gravity Mission to GRACE (2006)

NASA's Earth Science Technology office has funded an effort to advance the technology of interferometric ranging in Low Earth Orbit. The goal of this work is to reduce risk for a follow-on gravity mission to the gravity recovery and climate experiment (GRACE) by demonstrating performance of a heterodyne interferometric laser ranging instrument appropriate for a follow-on gravity mission to GRACE at the NASA Technology Readiness Level (TRL) 6, with traceability to the ranging error budget of a strawman flight design of the interferometric ranging system.
Synthesis of Sulfur-Bridged Polycycles via Pd-Catalyzed Dehydrogenative Cyclization (2014)

A general approach to sulfur-bridged polycycles by palladium-catalyzed double C(sp(2))-H bond oxidative cyclization is presented. This protocol afforded diverse sulfur-bridged five-, six-, and seven-membered polycycles in moderate to good yields with a tolerance for a wide variety of functional groups. A sulfide-bridged six-membered pyrene-thienoacene compound was synthesized readily using this method, and excellent performance for photoluminescence quantum yield was observed.
[Hospital personnel who are nasal carriers of methicillin-resistant Staphylococcus aureus. Usefulness of treatment with mupirocin]. (1992)

When a nosocomial outbreak of methicillin-resistant Staphylococcus aureus infections is detected, health care workers are one of the most important reservoirs. Topical treatment with mupirocin (nasal ointment) is useful for eliminating the nasal carrier status.
A low complexity turbo adaptive interference cancellation using antenna arrays for W-CDMA (2002)

This paper investigates an adaptive iterative space-time interference cancellation receiver for wideband code division multiple access (W-CDMA). Each iteration of the interference cancellation includes adaptive beamforming, adaptive path-combining and soft-input soft-output decoding. The complexity of the demodulation process using very simple normalized least mean square (N-LMS) adaptive algorithms is limited with no need of space-time channel estimation. Adaptive space-time processing algorithms are shown to benefit from the iterative process. Simulation results on a UMTS-like scenario show that this receiver achieves performance that is very close to the single user bound, even for highly interfered networks.
Precise, General, and Efficient Data-flow Analysis for Security Vetting of Android Apps (2018)

This dissertation presents a new approach to static analysis for security vetting of Android apps, and a general framework called Argus-SAF. Argus-SAF determines points-to information for all objects in an Android app component in a flow and context-sensitive (user-configurable) way and performs data-flow and data dependence analysis for the component. Argus-SAF also tracks inter-component communication activities. It can stitch the component-level information into the app- level information to perform intra-app or inter-app analysis. Moreover, Argus-SAF is NDK/JNI- aware and can efficiently track precise data-flow across language boundary. This dissertation shows that, (a) the aforementioned type of comprehensive app analysis is utterly feasible in terms of computing resources with modern hardware, (b) one can easily leverage the results from this general analysis to build various types of specialized security analyses – in many cases the amount of additional coding needed is around 100 lines of code, and (c) the result of those specialized analyses leveraging Argus-SAF is at least on par and often exceeds prior works designed for the specific problems, which this dissertation demonstrate by comparing Argus-SAF’s results with those of prior works whenever the tool can be obtained. Since Argus-SAF’s analysis directly handles intercomponent and inter-language control and data flows, it can be used to address security problems that result from interactions among multiple components from either the same or different apps and among java code and native code. Argus-SAF’s analysis is sound in that it can assure the absence of the specified security problems in an app with well-specified and reasonable assumptions on Android runtime system and its library.
Pigments, structures, and synthetic procedures (1994)

Recently, macroplastic (>5 mm) and especially microplastic (<5 mm) particles have been reported as emerging contaminants in marine and limnetic ecosystems. Their coloration is gained by the addition of pigments to the polymer blend which is the major component of the respective product. However, color is also a feature of paint and coatings whereby the pigment is the major component. Once abraded from a surface, paint particles may enter the environment via similar pathways as microplastic particles.So far no detailed studies of microplastic particles (pigmented and non-pigmented) as well as paint particles have been performed focusing on very small microparticles (1–50 μm), in either marine or limnetic ecosystems. Using Raman microspectroscopy with a spatial resolution down to 1 μm, we report a remarkable increase in the occurrence of (pigmented) microplastic particles below 500 μm. Among those, most particles were found at a size of ∼130 μm in a freshwater ecosystem (subalpine Lake Garda, Italy). Moreover, our qualitative and quantitative analyses revealed that the number of paint microparticles significantly increased below the size range of 50 μm due to their brittleness (the smallest detected paint particle had a size of 4 μm). Inductively coupled plasma mass spectrometry measurements showed that both colored particles found in nature as well as virgin particles contain a high variety of metals such as cadmium, lead and copper. These additives may elicit adverse effects in biota ingesting these microparticles, thus paints and associated compounds may act as formerly overlooked contaminants in freshwater ecosystems.
Surgical intervention for complications caused by late radiation damage of the small bowel: a retrospective analysis. (1993)

We studied the records of 46 patients who had been operated on between 1974 and 1990 in The Netherlands Cancer Institute because of complications due to late radiation damage of the small bowel. Data were collected on preoperative history, surgical intervention, postoperative complications and survival. By means of Cox's proportional hazards regression analysis we sought to identify factors that contribute to complication-risk and survival. The following factors led to an increase in complication-risk: hypoalbuminemia, more than one laparotomy prior to irradiation and a short interval (< 12 months) between irradiation and surgical intervention. The following factors related to a poorer survival: incomplete resection of the primary tumor and a short interval (< 12 months) between irradiation and surgical intervention. The type of surgical intervention did not have cumulative prognostic value in relation to complication-risk or survival. As patients undergoing resections differed considerably from patients undergoing bypass-procedures, no conclusions could be drawn about the superiority of one technique over the other. We think that both types of intervention have their own field of indication.
Quantitation of Antibody‐Secreting Cells in the Blood after Vaccination with a<i>Haemophilus influenzae</i>Type b Conjugate Vaccine (1990)

The human B-lymphocyte response to protein-conjugated polysaccharide antigens has not previously been studied at the cellular level. In order to do so, we developed and evaluated haemolytic plaque-forming cell assays detecting Haemophilus influenzae type b (Hib) capsular polysaccharide-specific antibody-secreting cells (AbSC) of the isotypes IgM, IgG, and IgA. The appearance of AbSC in the blood after vaccination of adults with diphtheria toxoid-conjugated Hib polysaccharide was investigated. AbSC were detected from post-vaccination day 5 to day 14. IgA was the predominant isotype among these cells. IgM AbSC peaked slightly earlier (median day 7) than IgG and IgA AbSC (both day 8). On post-vaccination day 8 the numbers of AbSC were: IgA, 1217/10(6) mononuclear cells (median); IgG, 211; and IgM, 30 (n = 11). Similar isotype distribution has earlier been found after vaccination with pure capsular polysaccharides from Hib and pneumococci. The predominance of IgA AbSC in response to both conjugate and pure polysaccharide vaccines is probably due to reactivation of the same clones of IgA-committed memory B cells originally primed at the mucosa by natural exposure to the polysaccharide or cross-reacting antigens.
1804/05『論理学・形而上学』研究I (1985)

Hegels Aufgabe in Jena war die Überwindung der Form der Reflexion. Die Vorlesung von "Logik-Metaphysik" 1804/05 einnimmt die wichtigen Stelle in der Entwicklung seiner Philosophie in Jena. Diese Aufgabe löst sich, wie mir scheint, durch die Untersuchung des Begriffs der "Unendlichkeit", die in dieser Vorlesung erörtert ist.
Hall conductivity of a two-dimensional graphite system (2002)

Within a self-consistent Born approximation, the Hall conductivity of a two-dimensional graphite system in the presence of a magnetic field is studied by quantum transport theory. The Hall conductivity is calculated for short- and long-range scatterers. It is calculated analytically in the limit of strong magnetic fields and in the Boltzmann limit in weak magnetic fields. The numerical calculation shows that the Hall conductivity displays the quantum Hall effect when the Fermi energy is in low-lying Landau levels and the scattering is weak. When the Fermi energy becomes away from $\ensuremath{\varepsilon}=0,$ it tends to the Boltzmann result.
Metalorganic chemical vapor deposition of BaTiO3 thin films (1991)

We report the results of a recent study on the in situ deposition of single phase BaTiO3 thin films by using the metalorganic chemical vapor deposition technique. The effects of growth parameters on the characteristics of the thin films were investigated in the substrate temperature range of 550–800 °C. Barium β-diketonate and titanium isopropoxide were used as the metal sources. Growth rates ranging from submicron to several microns per hour have been deposited on various substrates in an inverted vertical warm-wall reactor. X-ray diffraction data and Rutherford backscattering spectra provided the evidence for single BaTiO3 phase. Scanning electron microscopy was used to study the surface and the cross-sectional morphology of the films. Dielectric constant of the as-deposited film was around 250 at room temperature. The resistivity of the films were greater than 109 Ω cm.
Coupled equations for reverse time migration in transversely isotropic media (2010)

Abstract Reverse time migration (RTM) images reflectors by using time-extrapolation modeling codes to synthesize source and receiver wavefields in the subsurface. Asymptotic analysis of wave propagation in transversely isotropic (TI) media yields a dispersion relation describing coupled P- and SV-wave modes. This dispersion relation can be converted into a fourth-order scalar partial differential equation (PDE). Increased computational efficiency can be achieved using equivalent coupled second-order PDEs. Analysis of the corresponding dispersion relations as matrix eigenvalue systems allows one to characterize all possible coupled linear second-order systems equivalent to a given linear fourth-order PDE and to determine which ones yield optimally efficient finite-difference implementations. Setting the shear velocity along the axis of symmetry to zero yields a simpler approximate TI wave equation that is more efficient to implement. This simpler approximation, however, can become unstable for some plausible combinations of anisotropic parameters. The same eigensystem analysis can be applied using finite vertical shear velocity to obtain solutions that avoid these instability problems.

Research and Analysis of MIS System Integrity Based on 3S Technology (2011)

Through analyzing the current application of 3S Technology and MIS system, the paper puts forth the idea to establish the MIS system integrity based on 3S technology, and design the general structure model of the integrity system. The disadvantages of the above two systems can be overcome and their advantages can be complemented. The MIS system integrity based on 3S technology can be expected to offer a new thinking way and method for scientific research, governmental administration, and social production.
Performance Capability of a Damaged Lighter-Than-Air Vehicle Operating in the Near Space Regime (2006)

Abstract : This study investigates the ability of a high-altitude airship to maintain lift following the compromise of its lifting gas envelope. Accepted engineering principles are applied to develop a model that provides comparative analyses for airship depressurization alternatives following hull compromise. Specifically, maintaining lifting gas envelope overpressure to provide controllability in wind currents while sacrificing some buoyancy is compared with allowing envelope depressurization to occur with the goal of maintaining greater buoyancy as long as possible. The model provides insights to alternatives for recovering a damaged vehicle and its payload. In particular, the analysis demonstrates that maintaining the ability to navigate while forfeiting buoyancy can provide additional down-range maneuver capability. In some cases preserving the airship's hull overpressure for some period of time following compromise, vice allowing a slow depressurization to atmospheric equilibrium, extends the distance a damaged airship can sustain controlled navigation as much as eighty percent. However, the airship will forfeit nearly twenty percent of the altitude it would otherwise preserve by not forcing a constant hull overpressure.
Excimer laser lift-off for packaging and integration of GaN-based light-emitting devices (2003)

The delamination of a thin film heterostructure by selective absorption of pulsed laser energy at a buried interface enables the transfer of the thin film heterostructure from its growth substrate to virtually any receptor substrate without significant heating of material outside the interaction zone. By combining this "laser lift-off" process with low-temperature bonding methods, disparate classes of materials can be intimately integrated without exceeding the thermal budget of the least robust of the materials to be integrated. Furthermore, heterostructures that can be grown by epitaxy on one substrate can be transferred intact, without significant deterioration in crystal quality, to a receptor substrate that enhances the performance or functionality of the heterostructure in a device or microsystem. In this paper, applications of laser lift-off in the packaging and integration of light-emitting GaN devices are highlighted. Transfer of these devices from their sapphire growth substrates to thermally and electrically conductive receptor substrates is shown to result in improved device performance through the reduction of thermal and electrical series resistances, and by the improvement in optical design enabled by access to both sides of the heterostructure. Continued development of laser lift-off packaging has the potential to reduce manufacturing costs and complexity as well through the elimination of the sapphire dicing step. Finally, the application of the LLO technique to the assembly of functionally-enhanced microsystems is illustrated with the example of an integrated fluorescence detection microsystem.
Improved RF CMOS active inductor with high self resonant frequency (2010)

Many architectures of transistor only simulated inductors (TOSI) have been proposed until now in literature. Exhibiting tuning possibilities, low chip area and offering integration facility, they constitute promising architectures to replace passive inductors in RF circuits. An improved CMOS active inductor topology is proposed in this paper. With a novel loss compensation scheme, frequency increase up to 1.1 GHz (30%–66%) of the inductor self resonant frequency is achieved in the frequency band 1.5–3.3 GHz with large quality factors and very low current consumption. Besides, a more accurate passive model is proposed for CMOS TOSI active inductors and tested for this particular topology. Consisting of four parallel branches, it is still second order even though it contains three conservative elements. The model is sufficient general and proves superior performances over the classical RLC model mainly for higher frequencies. The simulations were carried out in a 0.18 um CMOS process.
Unsupervised feature learning framework for no-reference image quality assessment (2012)

In this paper, we present an efficient general-purpose objective no-reference (NR) image quality assessment (IQA) framework based on unsupervised feature learning. The goal is to build a computational model to automatically predict human perceived image quality without a reference image and without knowing the distortion present in the image. Previous approaches for this problem typically rely on hand-crafted features which are carefully designed based on prior knowledge. In contrast, we use raw-image-patches extracted from a set of unlabeled images to learn a dictionary in an unsupervised manner. We use soft-assignment coding with max pooling to obtain effective image representations for quality estimation. The proposed algorithm is very computationally appealing, using raw image patches as local descriptors and using soft-assignment for encoding. Furthermore, unlike previous methods, our unsupervised feature learning strategy enables our method to adapt to different domains. CORNIA (Codebook Representation for No-Reference Image Assessment) is tested on LIVE database and shown to perform statistically better than the full-reference quality measure, structural similarity index (SSIM) and is shown to be comparable to state-of-the-art general purpose NR-IQA algorithms.
High-breakdown-voltage AlSbAs/InAs n-channel field-effect transistors (1992)

InAs channel field-effect transistors of 1- mu m gate length were grown by molecular beam epitaxy and observed to operate at channel electric fields (20 kV/cm) higher than previously demonstrated and several times greater than the threshold for impact ionization in bulk InAs. Voltage gains on the order of 10 were observed with transconductances as high as 414 mS/mm and output conductances as low as 33 mS/mm. These voltage gains are comparable to those of GaAs-based devices and are the highest observed for InAs channel devices. The results demonstrate the potential for practical room-temperature operation of InAs FETs.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Measurement of Conduction-Electron Polarization via the Pairing Resonance (2009)

We show that the pairing resonance in the Pauli-limited normal state of ultrathin superconducting Al films provides a spin-resolved probe of conduction-electron polarization in thin magnetic films. A superconductor-insulator-ferromagnet tunneling junction is used to measure the density of states in supercritical parallel magnetic fields that are well beyond the Clogston-Chandresekhar limit, thus greatly extending the field range of the tunneling density of states technique. The applicability and limitations of using the pairing resonance as a spin probe are discussed.

The role of DNA flow cytometry in borderline malignant ovarian tumors (1996)

Reproducible DNA aneuploidy of high DI may be predicting a poor outcome, whereas the significance of inconsistently reproducible aneuploidy of low DI remains to be determined. Further studies of prospective DNA analysis with adequate sampling are necessary to define the role of flow cytometry in patients with borderline malignant ovarian tumors.
Characteristic basis function method: A new technique for efficient solution of method of moments matrix equations (2002)

Abstract In this paper, we introduce a novel approach for an efficient solution of matrix equations arising in the method of moments (MoM) formulation of electromagnetic scattering problems. This approach is based on the characteristic basis functions (CBFs), which are used to substantially reduce the matrix size because these bases are not bound by the conventional λ/20 domain discretization. As a result, it is possible to electrically solve large problems with much fewer unknowns than those needed when using conventional RWG basis functions. The accuracy and efficiency of the CBFs are demonstrated in a variety of scattering problems to illustrate the versatility of the approach. © 2002 Wiley Periodicals, Inc.

Cytokine-Induced Modulation of Colorectal Cancer (2016)

The emergence of novel immunomodulatory cancer therapies over the last decade, above all immune checkpoint blockade, has significantly advanced tumor treatment. For colorectal cancer (CRC), a novel scoring system based on the immune cell infiltration in tumors has greatly improved disease prognostic evaluation and guidance to more specific therapy. These findings underline the relevance of tumor immunology in the future handling and therapeutic approach of malignant disease. Inflammation can either promote or suppress CRC pathogenesis and inflammatory mediators, mainly cytokines, critically determine the pro- or anti-tumorigenic signals within the tumor environment. Here, we review the current knowledge on the cytokines known to be critically involved in CRC development and illustrate their mechanisms of action. We also highlight similarities and differences between CRC patients and murine models of CRC and point out cytokines with an ambivalent role for intestinal cancer. We also identify some of the future challenges in the field that should be addressed for the development of more effective immunomodulatory therapies.
A Scanning Electron Microscopic Study on Korean Rhus Lacquer Coats (1987)

This study was executed to investigate scanning electron microscopic characteristics of Korean Rhus lacquer coats. With the unrefined coat, distilled water, sodium hydroxide, acetic acid, ethyl alcohol, cold-check test, and accelerated weathering were performed after refining treatment. These treated lacquer coats were discussed through observation by scanning electron microscope and the obtained results were summarized as follows: 1. Compared with unrefined coat, the refined coat of Korean Rhus lacquer showed more even surface with regular distribution of dispression. 2. Korean Rhus lacquer coat heated at for 3 hours revealed no observable difference irrespective of refining and unrefining. 3. Korean Rhus lacquer coat treated by distilled water, sodium hydroxide, acetic acid. ethyl alcohol, cold-check test. and ultraviolet radiation showed significant characteristics compared with untreated coat. Especially. large deformation and checkings were observed by cold-check test and ultraviolet radiation respectively. 4. The Korean Rhus lacquer coat radiated by ultraviolet ray showed 0.11 duller and 1.41 brighter than non-radiated coat through color difference calculator.
