Virtual Repair: Geometric Reconstruction for Remanufacturing Gas Turbine Blades (2011)

The usage of Direct Metal Deposition (DMD) technology for repairing defective voids in high-value metallic components is time consuming, since traditional geometric reconstruction methods are not seamlessly connected to the DMD process. Here, we consider the development of a semi-automated geometric algorithm for “virtually” repairing defective voids that appear on gas turbine airfoils after extensive use. Our method produces an accurately reconstructed geometric model that can be used for generating DMD scanning paths, while ensuring both dimensional accuracy and topological consistency required by the airfoil design. This model is constructed by using the Sectional Gauss Map concept to generate a series of Prominent Cross Sections (PCS) along the longitudinal axis of a digitally acquired defective airfoil. The intrinsic geometry of the PCS lying in the non-defective region is then extrapolated across the defective region to fill in the voids. A boolean difference between the original defective model and the final reconstructed model yields a fully parameterized geometric representation of the repair volume. The test results of this method demonstrate the algorithm’s robustness and versatility over a wide range of airfoil defects.

S1660104 Optimal design of the patterned sapphire substrate from viewpoints of light extraction efficiency and crystalline quality of light emitting diodes (2014)

We calculated the influence of the surface structure of the patterned sapphire substrate (PSS) on the light extraction efficiency (LEE) of the light emitting diodes (LEDs) using the ray tracing method in order to find the optimal surface structure. Consequently, the LEE of the LEDs fabricated on the PSS with cone-shaped surface structure was higher than that of the LEDs on the PSS with pillar-shaped surface structure. The LEE of LEDs was improved with decreasing the ratio of c-plane-exposed surface etched by reactive etching. When the ratio of c-plane was minimum, the LEE was maximum during the taper angle of the corn-shaped surface structure was between 25 and 70 degrees. On the other hand, crystal growth of GaN was difficult when the ratio of c-plane surface is too small. We conclude that we should design the small ratio of c-plane-exposed surface under the condition which high crystalline quality GaN grows on the PSS and the taper angle of cone-shaped surface structure is controlled between 25 and 50 degrees to prevent the appearance of n-plane sapphire on which c-plane GaN grow easily.

Superconducting narrow-band filter for 2 GHz-band transmitter (2013)

We have developed a superconducting microstrip resonator for the narrow-band transmitting filter application, in order to achieve both high power handling capability and high unloaded Q value. For the superconducting microstrip resonator, it is necessary to suppress the radiation loss of the resonator in order to achieve high unloaded Q value and to reduce the maximum current density in the resonator to achieve high power handling capability, too. Therefore, by adopting an interdigital resonator consisting of two coupled comb resonators, we have reduced current density and suppressed the radiation loss. Using the interdigital resonators, we have fabricated an 8-pole pseudo-elliptic function filter that has about 2.0 GHz center frequency and 0.975% fractional bandwidth, and evaluated the power handling capability. As a result, we have confirmed that the power handling capability of the filter exceeds 40 W.
Orexigenic Action of Peripheral Ghrelin Is Mediated by Neuropeptide Y and Agouti-Related Protein (2004)

Ghrelin, a stomach-derived orexigenic hormone, has stimulated great interest as a potential target for obesity control. Pharmacological evidence indicates that ghrelin's effects on food intake are mediated by neuropeptide Y (NPY) and agouti-related protein (AgRP) in the central nervous system. These include intracerebroventricular application of antibodies to neutralize NPY and AgRP, and the application of an NPY Y1 receptor antagonist, which blocks some of the orexigenic effects of ghrelin. Here we describe treatment of Agrp(-/-);Npy(-/-) and Mc3r(-/-);Mc4r(-/-) double knockout mice as well as Npy(-/-) and Agrp(-/-) single knockout mice with either ghrelin or an orally active nonpeptide ghrelin agonist. The data demonstrate that NPY and AgRP are required for the orexigenic effects of ghrelin, as well as the involvement of the melanocortin pathway in ghrelin signaling. Our results outline a functional interaction between the NPY and AgRP pathways. Although deletion of either NPY or AgRP caused only a modest or nondetectable effect, ablation of both ligands completely abolished the orexigenic action of ghrelin. Our results establish an in vivo orexigenic function for NPY and AgRP, mediating the effect of ghrelin.

Kinetic modeling of [99mTc]TRODAT-1: a dopamine transporter imaging agent. (1999)

These findings suggest that the binding potential and corresponding kinetic rate constants can be reliably estimated in nonhuman primates with dynamic SPECT imaging of the dopamine transporter using a technetium-based tropane analogue. Furthermore, method II parameter vectors compare favorably to those produced using method I based on SEEs.
Semiclassical interpretation of the spin interference effect observed in square loop arrays of In0.53Ga0.47As/In0.52Al0.48As quantum wells (2011)

We present a semiclassical interpretation of the time-reversal spin interference (SI) observed in the square loop arrays made of In${}_{0.53}$Ga${}_{0.47}$As quantum wells [T. Koga et al., Phys. Rev. B 74, 041302 (2006)]. The simulated amplitude of SI as a function of the Rashba parameter $\ensuremath{\alpha}$ captured characteristic features in the experimental results if $\ensuremath{\gamma}\ensuremath{\lesssim}8$ eV \AA{}${}^{3}$ is assumed for the bulk Dresselhaus spin-orbit constant $\ensuremath{\gamma}$. Our work proves the validity of the semiclassical approach to predict the effect of time-reversal quantum interference in mesoscopic systems and the values of the spin-orbit coefficients recently deduced from the weak localization/antilocalization experiment.
Quantitative evaluation of the relaxivity effects of iodine on GD‐DTPA enhanced MR arthrography (2007)

A generalized relation for the relaxivities of Gd contrast in the presence of iodine was established. The side chains of iodine contrast were found to alter the relaxivities of Gd contrast. Imaging with proton density (PD)-weighted SE with only iodine contrast agent was found to be feasible.
Low Bandwidth Offload for Mobile AR (2016)

Environmental fingerprinting has been proposed as a key enabler to immersive, highly contextualized mobile computing applications, especially augmented reality. While fingerprints can be constructed in many domains (e.g., wireless RF, magnetic field, and motion patterns), visual fingerprinting is especially appealing due to the inherent heterogeneity in many indoor spaces. This visual diversity, however, is also its Achilles' heel -- matching a unique visual signature against a database of millions requires either impractical computation for a mobile device, or to upload large quantities of visual data for cloud offload. Further, most visual "features" tend to be low entropy -- e.g., homogeneous repetitions of floor and ceiling tiles. Our system VisualPrint, proposes a means to offload only the most distinctive visual data, that is, only those visual signatures which stand a good chance to yield a unique match. VisualPrint enables cloud-offloaded visual fingerprinting with efficacy comparable to using whole images, but with an order reduction in network transfer.
Fluctuations in Interleukin-6 Levels during Hemodialysis Sessions with Medium Cutoff Membranes: An Analysis on COVID-19 Case Series (2022)

This study describes over time variations in IL-6 levels of COVID-19 patients undergoing HD with MCO membranes. The trend for the changes of IL-6 levels during dialysis sessions was not uniform for all patients. Surviving patients had decreasing levels of IL-6 with consecutive dialysis sessions, while nonsurvivors had an increasing trend.

Building parallel runtime systems with Active Messages (2002)

Past research in communication infrastructure for parallel computing has shown that Active Messages is an attractive communication model that allows efficient implementations on a variety of architectures. This has been demonstrated through microbenchmarks, by including Active Messages in a runtime system for SplitC – a parallel SPMD extension of C, and by analyzing performance of a set of Split-C benchmarks. The goal of this work is to demonstrate that Active Messages are applicable for building a range of parallel runtime systems. Design and implementation issues are discussed in context of three programming languages: Split-C, CC++ and CRL, representing the three prominent parallel computing models: SPMD, MPMD and DSM, respectively.
Designing efficient genetic code expansion in Bacillus subtilis to gain biological insights (2021)

Abstract Bacillus subtilis is a model Gram-positive bacterium, commonly used to explore questions across bacterial cell biology and for industrial uses. To enable greater understanding and control of proteins in B. subtilis , we demonstrate broad and efficient genetic code expansion in B. subtilis by incorporating 20 distinct non-standard amino acids within proteins using 3 different families of genetic code expansion systems and two choices of codons. We use these systems to achieve click-labelling, photo-crosslinking, and translational titration. These tools allow us to demonstrate differences between E. coli and B. subtilis stop codon suppression, validate a predicted protein-protein binding interface, and begin to interrogate properties underlying bacterial cytokinesis by precisely modulating cell division dynamics in vivo . We expect that the establishment of this simple and easily accessible chemical biology system in B. subtilis will help uncover an abundance of biological insights and aid genetic code expansion in other organisms.

GLOBALISATION IN THE NEW MILLENNIUM: IMPLICATIONS FOR DEVELOPMENT AND DEMOCRACY IN AFRICA (2004)

The latter, however, has opened up new terrains of struggle for people, movements, and governments opposed to one—dimensional ‘corporate globalisation’, seeking instead the globalisation of social and environmental justice. A continent like Africa — much of which has sunk deeper into a “fourth world” status of extreme under—development, social instability and neo—colonial dependence — faces stark choices.
Brine Availability Test in Salt (BATS) FY21 Update (2021)

This report summarizes the 2021 fiscal year (FY21) status of ongoing borehole heater tests in salt funded by the disposal research and development (R&D) program of the Office of Spent Fuel & Waste Science and Technology (SFWST) of the US Department of Energy’s Office of Nuclear Energy’s (DOE-NE) Office of Spent Fuel and Waste Disposition (SFWD). This report satisfies SFWST milestone M2SF- 21SN010303052 by summarizing test activities and data collected during FY21. The Brine Availability Test in Salt (BATS) is fielded in a pair of similar arrays of horizontal boreholes in an experimental area at the Waste Isolation Pilot Plant (WIPP). One array is heated, the other unheated. Each array consists of 14 boreholes, including a central borehole with gas circulation to measure water production, a cement seal exposure test, thermocouples to measure temperature, electrodes to infer resistivity, a packer-isolated borehole to add tracers, fiber optics to measure temperature and strain, and piezoelectric transducers to measure acoustic emissions. The key new data collected during FY21 include a series of gas tracer tests (BATS phase 1b), a pair of liquid tracer tests (BATS phase 1c), and data collected under ambient conditions (including a period with limited access due to the ongoing pandemic) since BATS phase 1a in 2020. A comparison of heated and unheated gas tracer test results clearly shows a decrease in permeability of the salt upon heating (i.e., thermal expansion closes fractures, which reduces permeability).
Experimental test of equivalence principle with polarized masses (1990)

A torsion pendulum having masses with ${\mathrm{\ensuremath{\sim}}10}^{22}$ and ${\mathrm{\ensuremath{\sim}}10}^{23}$ polarized electrons is used to search for an anomalous spin interaction of macroscopic range. Competition from magnetic forces is reduced by using Dy-Fe masses (which exhibit orbital compensation of the electron intrinsic spin), combined with light magnetic shielding, so that the sensitivity is better than one-tenth of a percent of the gravitational force. Fluctuations set the overall experimental limit at about 8 times this level. Interpretation of our null result sets limits on electron spin interactions and on moments which are not of electromagnetic origin. In terms of a standard dipole-dipole form the result is (1.6\ifmmode\pm\else\textpm\fi{}6.9) \ifmmode\times\else\texttimes\fi{} ${10}^{\ensuremath{-}12}$ of the interaction strength between the magnetic moments of the electrons. Comparisons are made with theoretical predictions for very light exchange particles.
On the Perturb-and-Observe and Incremental Conductance MPPT Methods for PV Systems (2013)

This paper presents a detailed analysis of the two most well-known hill-climbing maximum power point tracking (MPPT) algorithms: the perturb-and-observe (P&O) and incremental conductance (INC). The purpose of the analysis is to clarify some common misconceptions in the literature regarding these two trackers, therefore helping the selection process for a suitable MPPT for both researchers and industry. The two methods are thoroughly analyzed both from a mathematical and practical implementation point of view. Their mathematical analysis reveals that there is no difference between the two. This has been confirmed by experimental tests according to the EN 50530 standard, resulting in a deviation between their efficiencies of 0.13% in dynamic and as low as 0.02% under static conditions. The results show that despite the common opinion in the literature, the P&O and INC are equivalent.
Electrophosphorescent Polymers for High-Efficiency Light-Emitting Diodes (2010)

Electrophosphorescent polymers are an important class of light-emitting materials that combine high electroluminescence efficiency of organometallic phosphohrescent complexes and solution processability of polymers. This review surveys the progress in the design, synthesis, characterization, photoluminescence and electroluminescence of electrophosphorescent polymers reported in the recent literatures. It focuses on polymers with phosphorescent guest covalent bonded to the polymers as a repeating unit in the main chain, a side chain, or polymer chain termini. The polymer backbones either have an extended π-electron conjugation or are non-conjugated. Important electrophosphorescent polymers and their performance in light emitting diodes are described.
Bmx Tyrosine Kinase Has a Redundant Function Downstream of Angiopoietin and Vascular Endothelial Growth Factor Receptors in Arterial Endothelium (2001)

The Bmx gene, a member of the Tec tyrosine kinase gene family, is known to be expressed in subsets of hematopoietic and endothelial cells. In this study, mice were generated in which the first coding exon of the Bmx gene was replaced with the lacZ reporter gene by a knock-in strategy. The homozygous mice lacking Bmx activity were fertile and had a normal life span without an obvious phenotype. Staining of their tissues using beta-galactosidase substrate to assess the sites of Bmx expression revealed strong signals in the endothelial cells of large arteries and in the endocardium starting between days 10.5 and 12.5 of embryogenesis and continuing in adult mice, while the venular endothelium showed a weak signal only in the superior and inferior venae cavae. Of the five known endothelial receptor tyrosine kinases tested, activated Tie-2 induced tyrosyl phosphorylation of the Bmx protein and both Tie-2 and vascular endothelial growth factor receptor 1 (VEGFR-1) stimulated Bmx tyrosine kinase activity. Thus, the Bmx tyrosine kinase has a redundant role in arterial endothelial signal transduction downstream of the Tie-2 and VEGFR-1 growth factor receptors.
Perceptually Motivated Time-Frequency Processing of Spatial Audio (2014)

This dissertation focuses on perceptually motivated processing of audio in the time-frequency domain, and on spatial audio in particular. The topic takes into account sound physics, perception, and digital signal processing (DSP).&#13;\nSound is emitted by a source in all directions with a pattern of directivity as a function of frequency, and it arrives to the listener through a direct path as well as through reverberation. The sounds from a multitude of sources superimpose at the ear canals. Due to the acoustic effect of the head, torso, and pinnae, the inter-aural, spectro-temporal characteristics of each arriving wave are specific to the direction of arrival. Ears transform the audio waveform into neural signals with frequency selectivity. Among other features, human hearing includes processes for analyzing the level and timing differences in the signals at the ears, which is necessary for obtaining information about the locations of the sound sources.&#13;\nIn perceptually motivated audio DSP, a key technique is to decompose the sound into frequency bands. Several perceptually relevant signal properties can be directly measured and processed in the frequency bands. Typically, the practical DSP design only approximates the hearing mechanisms and resolutions, and simultaneously also other features are optimized, such as the computational efficiency and latency.&#13;\nSeveral novel techniques were proposed as part of the dissertation work. The first is an optimized and versatile framework for frequency band processing of spatial audio. The method functions based on the channel energies and the inter-channel dependencies, which are key features for controlling the spatial perception. The method performs the translation of the spatial sound characteristics while minimizing the square difference between the produced waveform and a defined preferred waveform. The method also provides a means to apply the decorrelated sound energy to the minimum necessary extent. The method was applied to perform spatial sound reproduction based on a compact set of microphones, and its benefit with respect to legacy methods was confirmed by listening tests and simulations. In another study, a frequency band reverberator was proposed that produces diffuse late reverberation with low computational complexity and high perceptual quality. Finally, a phase-adaptive, multi-channel downmixer was proposed that avoids the spectral artifacts that would otherwise occur if the input channels include non-aligned but coherent sounds. The downmixer has been selected as part of the reference model 0 (RM0) of the MPEG-H standard.
