Computer vision based geometric calibration in curved multi-projector displays (2010)

In a multi-projector display system, geometric calibration is usually time-consuming and tedious. In this paper, we propose a multi-projector tiled display method with geometry parameters estimation. The method is used for analytic curved surface, such as cylindrical or spherical shaped display. The calibration process is automatic by using computer vision techniques; and in order to estimate the screen and projector parameters, a camera stereo pair with given internals is used to reconstruct 3D points on the screen. In this parametric approach, the camera doesn't have to cover the entire screen and the projectors can be placed roughly, which give the flexibility for various multi-projector display system. For scene rendering, our implementation is distributed, which is more efficient than the image transfer method with modern GPU. At last, we analyzed the effectiveness of the proposed method. Experimental results show that our approach supplied sufficient accuracy and enhanced the immersiveness.

An HMM Compensation Approach for Dynamic Features Using Unscented Transformation and its Application to Noisy Speech Recognition (2008)

In our previous work, a new HMM compensation approach for static MFCC features was proposed by using a technique called Unscented Transformation (UT). Three implementations of the UT approach with different computational complexities were evaluated on Aurora2 connected digits database, and significant performance improvements were achieved compared to log-normal- approximation-based PMC (Parallel Model Combination) and first- order-approximation-based VTS (Vector Taylor Series) approaches. In this paper, we extend our UT-based formulation to compensating for HMM parameters corresponding to both static and dynamic features. New experimental results on Aurora2 task are reported to demonstrate the effectiveness of the proposed UT approach.

Optimization of logical rules derived by neural procedures (2003)

Neural networks are used for initial determination of linguistic variables and extraction of logical rules from data. Hierarchical sets of rules for different accuracy/rejection trade-offs are obtained. Sets of logical rules are optimized by maximization of their predictive power. To avoid global minimization methods for crisp logical rules Gaussian uncertainties of inputs are assumed. Analytical formulas reproducing Monte Carlo results for such inputs are derived, leading to a "soft trapezoidal" membership functions instead of rectangular functions used for crisp logical rules. Such approach increases accuracy, gives probabilities of classification instead of the yes/no answers, and allows one to optimize sets of rules using gradient procedures. A few illustrative applications to benchmark and real life problems show the effectiveness of this approach.
Influence of Molecular Excluded Volume and Connectivity on the Nanoscale Morphology of Conjugated Polymer/Small Molecule Blends (2018)

Over the past couple of decades, organic photovoltaics (OPV) based on conjugated polymer/fullerene derivative bulk heterojunctions have been extensively studied, resulting in single-junction efficiencies of order 10%. The need to push the efficiency toward 15% has resulted in the synthesis of a large number of non-fullerene electron acceptors with ever-increasing absorption coefficients in the red. Though some new acceptors have recently begun to be competitive with the fullerene, there is very little systematic understanding of which molecular geometries and spatial frontier orbital extent correlate with improved performance. One of the most important factors that determines the OPV efficiency is the nanoscale, phase-separated morphology of the blend. In this article, using a combination of resonant elastic X-ray scattering and elemental mapping, we investigate the influence of relatively small chemical changes to a nonplanar conjugated small molecule on the nanoscale morphology of the resulting polymer/molecule blend. We find that subtle modifications of the number and placement of peripheral functional groups can have an enormous influence on the length scale of phase separation. We then quantify the extent of phase separation by using the generalized indirect Fourier transform to convert resonant scattering intensities to pair-distance distribution functions. Our results point toward the large influence of the molecular excluded volume as a major morphology determinant. This work has implications for synthetic efforts to create non-fullerene electron acceptors that can substantially outcompete fullerenes in OPV devices.
The Spatial-Perceptual Design Space: A New Comprehension for Data Visualization (2007)

We revisit the design space of visualizations aiming at identifying and relating its components. In this sense, we establish a model to examine the process through which visualizations become expressive for users. This model has lead us to a taxonomy oriented to the human visual perception. The essence of this taxonomy provides natural criteria in order to delineate a novel understanding for the design space of visualizations. From such understanding, we elaborate a model for generalized design. The model poses an intuitive comprehension for the visualization design space departing from fundamental pre-attentive stimuli and from perceptual phenomena. The paper is presented as a survey, its structure introduces an alternative conceptual organization for the space of techniques concerning visual analysis.

Microcellular Plastics (2003)

Abstract Microcellular plastics (MCPs) refer to any plastic with tiny bubbles of less than about 50 μm. They are made by subjecting polymers with a large amount of dissolved gas to a thermodynamic instability so as to nucleate a large number of cells instantaneously. MCPs have been extruded and injection‐molded in order to make various industrial products. This article reviews the fundamental theory for design of MCPs and their processing methods. It also discusses the design of equipment, including the die or mold, for MCP processing. The performance of MCPs and the advantages of using MCPs are demonstrated. Some of their industrial applicatons are also highlighted.
Spontaneous Otoacoustic Emissions inTectaY1870C/+Mice Reflect Changes in Cochlear Amplification and How It Is Controlled by the Tectorial Membrane (2018)

Spontaneous otoacoustic emissions (SOAEs) recorded from the ear canal in the absence of sound reflect cochlear amplification, an outer hair cell (OHC) process required for the extraordinary sensitivity and frequency selectivity of mammalian hearing. Although wild-type mice rarely emit, those with mutations that influence the tectorial membrane (TM) show an incidence of SOAEs similar to that in humans. In this report, we characterized mice with a missense mutation in <i>Tecta,</i> a gene required for the formation of the striated-sheet matrix within the core of the TM. Mice heterozygous for the Y1870C mutation (<i>Tecta<sup>Y1870C/+</sup></i> ) are prolific emitters, despite a moderate hearing loss. Additionally, Kimura's membrane, into which the OHC stereocilia insert, separates from the main body of the TM, except at apical cochlear locations. Multimodal SOAEs are also observed in <i>Tecta<sup>Y1870C/+</sup></i> mice where energy is present at frequencies that are integer multiples of a lower-frequency SOAE (the primary). Second-harmonic SOAEs, at twice the frequency of a lower-frequency primary, are the most frequently observed. These secondary SOAEs are found in spatial regions where stimulus-evoked OAEs are small or in the noise floor. Introduction of high-level suppressors just above the primary SOAE frequency reduce or eliminate both primary and second-harmonic SOAEs. In contrast, second-harmonic SOAEs are not affected by suppressors, either above or below the second-harmonic SOAE frequency, even when they are much larger in amplitude. Hence, second-harmonic SOAEs do not appear to be spatially separated from their primaries, a finding that has implications for cochlear mechanics and the consequences of changes to TM structure.
MAS: Standalone Microwave Resonator to Assess Muscle Quality (2021)

Microwave-based sensing for tissue analysis is recently gaining interest due to advantages such as non-ionizing radiation and non-invasiveness. We have developed a set of transmission sensors for microwave-based real-time sensing to quantify muscle mass and quality. In connection, we verified the sensors by 3D simulations, tested them in a laboratory on a homogeneous three-layer tissue model, and collected pilot clinical data in 20 patients and 25 healthy volunteers. This report focuses on initial sensor designs for the Muscle Analyzer System (MAS), their simulation, laboratory trials and clinical trials followed by developing three new sensors and their performance comparison. In the clinical studies, correlation studies were done to compare MAS performance with other clinical standards, specifically the skeletal muscle index, for muscle mass quantification. The results showed limited signal penetration depth for the Split Ring Resonator (SRR) sensor. New sensors were designed incorporating Substrate Integrated Waveguides (SIW) and a bandstop filter to overcome this problem. The sensors were validated through 3D simulations in which they showed increased penetration depth through tissue when compared to the SRR. The second-generation sensors offer higher penetration depth which will improve clinical data collection and validation. The bandstop filter is fabricated and studied in a group of volunteers, showing more reliable data that warrants further continuation of this development.
Near-infrared studies of nova V5584 Sgr in the pre-maximum and early\n decline phase (2014)

We present near-infrared spectroscopic and photometric observations of nova\nV5584 Sgr taken during the first 12 days following its discovery on Oct. 26.439\nUT 2009. The evolution of the spectra is shown from the initial P Cygni phase\nto an emission line phase. The prominent carbon lines seen in the JHK spectra\nclosely match those observed in a FeII class nova outburst. The spectra show\nfirst-overtone CO bands in emission between 2.29-2.40 micron. By examining WISE\nand other publicly available data, we show that the nova underwent a pronounced\ndust formation phase during February - April 2010.\n
Building a Semantic Parser Overnight (2015)

How do we build a semantic parser in a new domain starting with zero training examples? We introduce a new methodology for this setting: First, we use a simple grammar to generate logical forms paired with canonical utterances. The logical forms are meant to cover the desired set of compositional operators, and the canonical utterances are meant to capture the meaning of the logical forms (although clumsily). We then use crowdsourcing to paraphrase these canonical utterances into natural utterances. The resulting data is used to train the semantic parser. We further study the role of compositionality in the resulting paraphrases. Finally, we test our methodology on seven domains and show that we can build an adequate semantic parser in just a few hours.

Role of platelet-activating factor acetylhydrolase gene mutation in childhood immunoglobulin A nephropathy. (1998)

血小板活性化因子 (PAF) は，炎症前駆細胞の活性化や血管透過性亢進作用を有し，腎炎の発症進展に関与することが報告されてきた。最近日本人の家系にPAF分解酵素 (PAF acetylhydrolase) 遺伝子エクソン9の点変異 (G994T) が発見され，ホモ，ヘテロの遺伝子型は，血中PAF分解酵素レベルが低下していることが判明した。このような点変異を持つ人では，PAF濃度の上昇が容易に生じ，より強い炎症を引き起こす可能性が考えられる。今回私たちは，IgA腎症の発症進展にPAF分解酵素の遺伝子変異が関与しているかどうかを検討した。神戸大学小児科にて腎生検を受けたIgA腎症小児89名を対象とし，また，100名の健常成人をコントロールとした。末梢血白血球よりDNAを抽出後，PCR法を用いて，遺伝子変異 (G994T) を明らかにし，決定されたgenotype (GG: GT: TT) と臨床病理所見とを比較検討した。遺伝子変異は，IgA腎症群と正常コントロール群では差異はなかった。しかし遺伝子変異を持つ群 (GT/TT genotypes，N=30) は，持たない群 (GG genotype，N=59) に比較して，1日尿中蛋白排泄量が有意に増加していた。また，腎組織所見では，メサンギウム増殖を示す糸球体の割合は，遺伝子変異を持つ群が，持たない群に比較して有意に増加していた。PAF分解酵素遺伝子エクソン9の点変異 (G994T) は，小児期IgA腎症の蛋白尿やメサンギウム増殖などの病態に関与する。
Aging-Related Calcium Dysregulation in Rat Entorhinal Neurons Homologous with the Human Entorhinal Neurons in which Alzheimer’s Disease Neurofibrillary Tangles First Appear (2018)

Aging is the leading risk factor for idiopathic Alzheimer's disease (AD), indicating that normal aging processes promote AD and likely are present in the neurons in which AD pathogenesis originates. In AD, neurofibrillary tangles (NFTs) appear first in entorhinal cortex, implying that aging processes in entorhinal neurons promote NFT pathogenesis. Using electrophysiology and immunohistochemistry, we find pronounced aging-related Ca2 + dysregulation in rat entorhinal neurons homologous with the human neurons in which NFTs originate. Considering that humans recapitulate many aspects of animal brain aging, these results support the hypothesis that aging-related Ca2 + dysregulation occurs in human entorhinal neurons and promotes NFT pathogenesis.
The Syntrophin-Dystrobrevin Subcomplex in Human Neuromuscular Disorders (2005)

The syntrophins and alpha-dystrobrevin form a subcomplex with dystrophin at the skeletal muscle membrane, and are also highly concentrated at the neuromuscular synapse. Here we demonstrate that the different syntrophins and alpha-dystrobrevin isoforms have distinct expression patterns during human skeletal muscle development, and are differentially affected by loss of dystrophin anchorage and denervation in human neuromuscular disease. During normal fetal development, and in Duchenne muscular dystrophy and denervation disorders, alpha1-syntrophin and alpha-dystrobrevin are absent or markedly reduced at the sarcolemmal membrane. beta1-Syntrophin is the predominant syntrophin isoform expressed at the muscle membrane during development, and it undergoes upregulation in response to loss of alpha1-syntrophin in Duchenne muscular dystrophy and in denervation. Upregulation of beta1-syntrophin in neuromuscular disorders is associated with re-expression of the fetal nicotinic acetylcholine receptor gamma-subunit, cardiac actin, and neonatal myosin, suggesting reversion of muscle fibers to an immature phenotype. We show that denervation specifically affects expression of the syntrophin-dystrobrevin subcomplex and does not affect levels or localization of other members of the dystrophin-associated protein complex. Our results confirm that dystrophin is required for anchorage of the syntrophin-dystrobrevin subcomplex and suggest that expression of the syntrophin-dystrobrevin complex may be independently regulated through neuromuscular transmission.

Application of rubber friction to FEA models of rubber sealing (2019)

O-ring type elastomer seals are common in different industries. Friction plays a critical role on the setting and actual performance of the components. Design for gland dimensions, compression levels, extrusion gap size and pressure ratings are well known in the industry. The viscoelastic effects however, are not commonly accounted for. Simulation packages use fixed friction coefficients, or pressure dependent ones. If this is the case, then dependence of frictional behaviour is purely obtained from the instantaneous stress response. Temperature changes are then only related to changes in elastic modulus, ignoring viscoelastic behaviour altogether. Also, polished surfaces still have a significant roughness contribution to friction at higher setting speeds (&gt;10mm/s). An experimental O-ring friction testing is used to observe the effects temperature, surface roughness, speed and pressure on rubber friction. FEA is used to obtain the normal force to help calculate changes in the coefficient of friction.

Mevva ion source operated in purely gaseous mode (2004)

We have operated a vacuum arc ion source in such a way as to form beams of purely gaseous ions. The vacuum arc configuration that is conventionally used to produce intense beams of metal ions was altered so as to form gaseous ion beams, with only minimal changes to the external circuitry and no changes internally to the ion source. In our experiments we formed beams from oxygen (O+ and O2+), nitrogen (N+ and N2+), argon (Ar+), and carbon dioxide (C+, CO2+, O+, and O2+) at extraction voltage of 2–50 kV. We used a pulsed mode of operation, with beam pulses ∼50 ms long and repetition rate 10 pulses per second, for a duty cycle of about 50%. Downstream ion beam current as measured by a 5 cm diameter Faraday cup was typically 0.5 mA pulse or about 250 μA time averaged. This time averaged beam current is very similar to that obtained for metal ions when the source is operated in the usual vacuum arc mode. Here we describe the modifications made to the source and the results of our investigations.

The article notes that the question of what tests courts should use in deciding whether to reveal the identities of anonymous Internet users is unsettled. Part II of the Article discusses the various tests courts have applied in determining whether the identity of an anonymous Internet user should be revealed—including a good-faith test, a summary judgment standard, and a balancing test. Part III analyzes the merits of each test. Finally, Part IV concludes by recommending the appropriate test courts should use in deciding whether to reveal the identities of anonymous Internet users.
MR IMAGING OF DISPLACED MENISCAL TEARS OF THE KNEE. Importance of a "disproportional posterior horn sign" (2001)

Purpose: Meniscal tears associated with displaced fragments are clinically significant. We propose the “disproportional posterior horn sign” as a supportive criterion to identify a posterocentrally displaced meniscal fragment on MR imaging studies. If the meniscal posterior horn in the central portion appears larger than that in the peripheral section, it is considered positive for “disproportional posterior horn sign”.



Material and Methods: MR images obtained in 42 patients with 43 lesions, confirmed to have displaced meniscal tears, were included in this study. The MR images were retrospectively evaluated for the presence of the “disproportional posterior horn sign”, as well as the other known signs.



Results: The “disproportional posterior horn sign” was seen in 9 (20.9%) of 43 lesions, including 1 lateral discoid meniscal tear, 5 lateral meniscal tears and 3 medial meniscal tears. Five of them also had other signs of a displaced meniscal fragment. However, the remaining 4 cases only exhibited the “disproportional posterior horn sign”. For the other MR signs, the “absent bow tie sign” was detected in 40 (93%) of 43 lesions, the “flipped meniscus sign” in 27 (62.8%) of 43 lesions, the “double posterior cruciate ligament sign” in 17 (39.5%) of 43 lesions and the “notch fragment sign” in 22 (51.2%) of 43 lesions.



Conclusion: The “disproportional posterior horn sign” is helpful in demonstrating a posterocentrally displaced meniscal fragment, especially when other characteristic signs are unremarkable or absent.
Fumigant Activity of Four Plant Powders against Cowpea Weevil, Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) in Stored Adzuki Bean (2021)

Background: Cowpea weevil, Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) is one of most common species pest that attack various types of beans in the storage. Plant-based insecticides are considered as good candidates as alternatives to methyl bromide and phosphine for controlling pest in storage. Plenty of reports about plant powder as grain protectant, conversely a little information on plant powder as fumigant had been reported. This study was designed to observe the effects of plant powders of clove, holy basil, lemongrass and turmeric as fumigant on the biological parameters of C. maculatus under laboratory conditions. Methods: Experiments were conducted on plant powders against biological parameters of cowpea weevil. No choice test method was followed to assess the bioefficacy of the four natural fumigants on adult longevity, fecundity, F1 progeny, bean damage and weight loss of bean under completely randomized design (CRD). Result: Fumigant toxicity of four plant powders (clove, holy basil, lemongrass and turmeric) varied amongst doses. Clove powder showed significantly lower adult longevity, fecundity of female, number of F1 progeny, bean damage and weight loss of bean at 1 g and 3 g dose per container. Major volatile organic compounds (VOCs) in clove powder were eugenol (48.64%) and caryophyllene (43.09%) identified by solid phase microextraction followed with gas chromatography and mass spectrometry (SPME-GC/MS). These two major constituents might explain the fumigant toxic activities of clove powder towards C. maculatus biological parameters.
