Bottom and Concave Surface Rendering in Image-based Visual Hull (2009)

Bottom and concave shapes on object surface are difficult to reconstruct in image-based visual hull method. In this paper, we propose a simple but efficient method to solve these problems in regular image-based visual hull framework. With the help of a simple image acquiring platform which involves a glass and a mirror, we can capture images of the object from both upper and lower side at the same time. Using these images, silhouette cones necessary for reconstructing the bottom and the concave surfaces could be generated. Therefore the final rendering result of the object can be significantly improved in accuracy and reality, especially in the parts of bottom and concaves.
Sample handling for kinetics and molecular assembly in flow cytometry (1998)

Flow cytometry discriminates particle associated fluorescence from the fluorescence of the surrounding medium. It permits assemblies of macromolecular complexes on beads or cells to be detected in real-time with precision and specificity. The authors have investigated two types of robust sample handling systems which provide sub-second resolution and high throughput: (1) mixers which use stepper-motor driven syringes to initiate chemical reactions in msec time frames; and (2) flow injection controllers with valves and automated syringes used in chemical process control. In the former system, the authors used fast valves to overcome the disparity between mixing 100 {micro}ls of sample in 100 msecs and delivering sample to a flow cytometer at 1 {micro}l/sec. Particles were detected within 100 msec after mixing, but turbulence was created which lasted for 1 sec after injection of the sample into the flow cytometer. They used optical criteria to discriminate particles which were out of alignment due to the turbulent flow. Complex sample handling protocols involving multiple mixing steps and sample dilution have also been achieved. With the latter system they were able to automate sample handling and delivery with intervals of a few seconds. The authors used a fluidic approach to defeat turbulence caused by sample introduction. By controlling both sheath and sample with individual syringes, the period of turbulence was reduced to {approximately} 200 msecs. Automated sample handling and sub-second resolution should permit broad analytical and diagnostic applications of flow cytometry.
The Effect Of Oxygen On Stability In CLAP Glasses (1987)

A small amount of oxygen is shown to be necessary to form CdF<sub>2</sub>-LiF-A1F<sub>3</sub>-PbF<sub>2</sub> (CLAP) glasses. Too little oxygen produces order of magnitude increases in crystallization, too much oxygen produces liquid-liquid phase separation. A microcrystallite structure is suggested to explain these results.
Polyimides containing pendent trifluoromethyl.groups (1993)

Several new polyimides containing trifluoromethyl groups were prepared from the reaction of various aromatic dianhydrides and two new diamines containing trifluoromethyl groups, 4,4'.bis(3-amino-5-trifluoromethylphenoxy)biphenyl and 1,4-bis(3-amino-5-trifluoromethylphenoxy)benzene. The diamines were prepared from the aromatic nucleophilic displacement of the disodium salts of 4,4'-biphenol or hydroquinone with 3,5-dinitrobenzotrifluoride followed by hydrogenation of the resultant dinitro compounds. The thermally cured polyimides exhibited glass transition temperatures between 186 and 262 C. By thermogravimetric analysis, the polyimides exhibited 5% weight losses at 484-527 C in nitrogen and 452-506 C in air.
Fresh Brain Tissue Diagnostics Using Raman Spectroscopy in Humans (2018)

A key part of treatment for brain tumors is tumor resection, the amount of tumor resection has a direct correlation on the mortality of the patient. However, tools available to surgeons to ensure maximal resection while preserving a patient's functional status often increase surgery time or are lacking in accuracy. Raman spectroscopy is a promising modality that can provide real time intraoperative data to the surgeon about whether a tissue is normal or cancerous, thus aiding the surgeon in obtaining maximal safe resection. In this paper, we pair Raman spectroscopy with a supervised machine learning technique, support vector machine, to classify fresh tissue samples as solid tumor, infiltrating tumor, necrosis, or normal brain tissue. The support vector machine classifier resulted in 89% accuracy of the 117 tissue samples while delivering real time results. Accurate real-time tissue characterization will vastly reduce the amount of time a surgeon waits for the results of biopsies and provides a means for intraoperative margin assessment during tumor resection.
<title>Real-time holography using the high-resolution LCTV-SLM</title> (1991)

The real-time holography system with a liquid-crystal television spatial light modular (LCTV- SLM) is presented. In the system, the LCTV-SLM is used as a phase hologram device. On the recording, the in-line holography method is used to reduce the spatial frequency of the fringe pattern of the hologram. The CCD camera detects the fringe pattern, and the fringe-pattern signal is transferred to the LCTV-SLM through the video-signal line. On the reconstruction process, the LCTV-SLM is illuminated by an He-Ne laser (633nm) and the spatial filtering technique is used to remove the zero and the higher-order diffracted light. Thus the holographic image of the real object can be observed continuously in real-time.
Assessing sperm DNA fragmentation in the field: an adaptation of sperm chromatin dispersion technology (2008)

The sperm chromatin dispersion (SCD) test is a new technique that allows assessment of sperm DNA fragmentation (SDF) in different species. The application of this technique, like other techniques, is restricted to the laboratory. Our investigation was aimed at exploring the possibilities of extending SCD methodology for use in the field, where electric powered facilities such as freezers, microscopes or heaters are not available. Our results showed that SCD methodology, with minor modifications to the standard protocol, can be performed readily in the field, offering reliable information about SDF. An Light Emitting Diode (LED)-equipped microscope attached to a laptop, a gas heater and a CO(2) spray for cooling are sufficient to assess the quality of sperm DNA. The results obtained after assessing 10 different semen samples under different conditions (30 degrees C in the laboratory and at 17 degrees C and 4 degrees C in the field) showed that except after processing the slides at 4 degrees C, the results of SDF in different animals showed no significant differences. With the modifications suggested here, the SCD technique can be used to assess SDF in the wild. In particular, the DNA quality of spermatozoa obtained from animals post mortem can be assessed in the field.
Piezoelectric and ferroelectric properties of P (VDF-TrFE) copolymers and their application to ultrasonic transducers (1984)

Abstract The copolymers of vinylidene fluoride (VDF) and trifluoroethylene (TrFE) have been found to be effective ultrasonic transducer materials because of their large electromechanical coupling factor kt . On the basis of the results obtained by SEM, X-ray diffraction, and ferroelectric polarization reversal studies of copolymer films, the large kt is ascribed to their high remanent polarization, which may originate from high crystallinity and preferential orientation of well-grown crystallites. Various single element transducers for medical ultrasound imaging have been developed utilizing PVDF and P(VDF-TrFE) films. The performance of these transducers is in good agreement with a theoretical prediction in which their dielectric and mechanical losses are taken into account. The P(VDF-TrFE) transducers have a two-pathway sensitivity 10 dB higher than that of PVDF transducers. They give high resolution medical images much superior in quality to those obtained with conventional ceramic transducers. Linear transducer arrays of P(VDF-TrFE) also give ultrasound images which show their potentiality for real-time imaging.

Alternatives to conjunctive query processing in peer-to-peer file-sharing systems (2009)

Peer-to-peer file-sharing systems suffer from the over-specification of query results due to the fact that query processing is conjunctive and the descriptions of shared files are sparse. Ultimately, longer queries, which should yield more accurate results, do the opposite. To alleviate this problem, we consider alternative means of query processing. That is, results are sent from the server to the client only if they are deemed relevant based on cosine similarity. Based on our results, these alternatives can increase query accuracy by 40% at virtually no cost.
Clinical Metagenomic Next-Generation Sequencing for Pathogen Detection (2018)

Nearly all infectious agents contain DNA or RNA genomes, making sequencing an attractive approach for pathogen detection. The cost of high-throughput or next-generation sequencing has been reduced by several orders of magnitude since its advent in 2004, and it has emerged as an enabling technological platform for the detection and taxonomic characterization of microorganisms in clinical samples from patients. This review focuses on the application of untargeted metagenomic next-generation sequencing to the clinical diagnosis of infectious diseases, particularly in areas in which conventional diagnostic approaches have limitations. The review covers ( a) next-generation sequencing technologies and common platforms, ( b) next-generation sequencing assay workflows in the clinical microbiology laboratory, ( c) bioinformatics analysis of metagenomic next-generation sequencing data, ( d) validation and use of metagenomic next-generation sequencing for diagnosing infectious diseases, and ( e) significant case reports and studies in this area. Next-generation sequencing is a new technology that has the promise to enhance our ability to diagnose, interrogate, and track infectious diseases.
Isolation, Structure Elucidation, and Antitumor Activity of Spirohexenolides A and B (2009)

In this report, we describe the discovery of a pair of bioactive spirotetronates, spirohexenolides A (1) and B (2), that arose from the application of mutagenesis, clonal selection techniques, and media optimization to strains of Streptomyces platensis. The structures of spirohexenolides A (1) and B (2) were elucidated through X-ray crystallography and confirmed by 1D and 2D NMR studies. Under all examined culture conditions, spirohexenolide A (1) was the major metabolite with traces of spirohexenolide B (2) arising in cultures containing increased loads of adsorbent resins. Spirohexenolide A (1) inhibited tumor cell growth with GI(50) values spanning from 0.1 to 17 microM across the NCI 60 cell line panel. An increased activity was observed in leukemia (GI(50) value of 254 nM in RPMI-8226 cells), lung cancer (GI(50) value of 191 nM in HOP-92 cells), and colon cancer (GI(50) value of 565 nM in SW-620 cells) tumor cells. Metabolite 1 was fluorescent and could be examined on a confocal fluorescent microscope with conventional laser excitation and filter sets. Time lapse imaging studies indicated that spirohexenolide A (1) was readily taken up by tumor cells, appearing through the cell immediately after dosing and subcellularly localizing in the lysosomes. This activity, combined with a unique selectivity in NCI 60 cancer cell line screening, indicates that 1 warrants further chemotherapeutic evaluation.
A New Family of Tunable Indolylphosphine Ligands by One-Pot Assembly and Their Applications in Suzuki−Miyaura Coupling of Aryl Chlorides (2008)

This study describes a new class of indolylphosphine ligands, which can be easily accessed by a simple one-pot assembly from commercially available indoles, acid chlorides, and chlorophosphines. A combination of these three starting materials provides a high diversification of the ligand structure. The application of this ligand array in palladium-catalyzed Suzuki-Miyaura coupling reaction of aryl chlorides with arylboronic acids is described. A catalyst loading down to 0.01 mol % of Pd can be achieved.
Control of Early Solidification in Continuous Casting by Horizontal Oscillation in Synchronization with Vertical Oscillation of the Mold. (1998)

A new method of mold oscillation for continuous casting termed "horizontal oscillation" was developed to reduce the depth of oscillation marks without increasing the possibility of breakout. In this method, the wide faces of the mold oscillate horizontally in synchronization with conventional vertical oscillation. Oscillation marks on slabs of SUS304 cast with a pilot continuous caster were examined under various conditions of mold oscillation. Horizontal oscillation successfully reduced the depth of oscillation marks and surface segregation at oscillation marks, and was extremely effective when the wide face of the mold was expanded against the solidified shell during positive strip time. Experiments with an actual machine reproduced these effects of horizontal oscillation. A numerical analysis of the deformation of the solidified shell during one cycle of vertical oscillation was performed to study the effect of horizontal oscillation on the control of early solidification near the meniscus. Friction force acting on the shell near meniscus was also discussed to explain the reduction in the surface segregation.

Sr<sub>9</sub>Mg<sub>1.5</sub>(PO<sub>4</sub>)<sub>7</sub>:Eu<sup>2+</sup>: A Novel Broadband Orange-Yellow-Emitting Phosphor for Blue Light-Excited Warm White LEDs (2015)

A new orange-yellow-emitting Sr9Mg(1.5)(PO4)7:Eu(2+) phosphor was prepared via high-temperature solid-state reaction. The structure and optical properties of it were studied systematically. Sr9Mg(1.5)(PO4)7:Eu(2+) can be well-excited by 460 nm blue InGaN chips and exhibit a wide emission band covering from 470 to 850 nm with two main peaks centered at 523 and 620 nm, respectively, which originate from 5d-4f dipole-allowed transitions of Eu(2+) in different crystallographic sites. The sites attribution, concentration quenching, fluorescence decay analysis, and temperature-dependent luminescence properties were investigated in detail. Furthermore, a warm white LED device was fabricated by combining a 460 nm blue InGaN chip with the optimized orange-yellow-emitting Sr9Mg(1.5)(PO4)7:Eu(2+). The color coordinate, correlated color temperature and color rendering index of the fabricated LED device were (0.393, 0.352), 3437 K, and 86.07, respectively. Sr9Mg(1.5)(PO4)7:Eu(2+) has great potential to serve as an attractive candidate in the application of blue light-excited warm white LEDs.
Highly Diastereo- and Enantioselective Intramolecular Amidation of Saturated CH Bonds Catalyzed by Ruthenium Porphyrins (2002)

Virtually complete diastereoselectivity is observed in the intramolecular amidation of saturated CH bonds, catalyzed by the ruthenium porphyrin catalyst 1 or 2. Reactions of sulfamate esters with PhI(OAc)2 in the presence of 1 or 2 afforded cyclic sulfamidates in up to 87 % ee.
Robust Reputation Management Using Probabilistic Message Passing (2011)

In a typical reputation management system, after each transaction, the buyer (who receives a service or purchases a product) provides its report/rating about the quality of the seller for that transaction. In such a system, the problem of reputation management is to compute two sets of variables: 1. the (global) reputation parameters of entities who act as sellers, and 2. the trustworthiness parameters of the entities who act as the raters (i.e., buyers). In this paper, for the first time, we introduce an iterative probabilistic method for reputation management. The proposed scheme, referred to as RPM, relies on a probabilistic message passing algorithm in the graph-based representation of the reputation management problem on an appropriately chosen factor graph. In the graph representation of the problem, the sellers and buyers are arranged as two sets of variable and factor nodes, respectively, that are connected via some edges. Then, the reputation and trustworthiness parameters are computed by a fully iterative and probabilistic message passing algorithm between these nodes in the graph. We provide a detailed evaluation of RPM via computer simulations. We observe that RPM iteratively reduces the error in the reputation estimates of the sellers due to the malicious raters. Finally, comparison of RPM with some well- known and commonly used reputation management techniques (e.g., Averaging Scheme, Bayesian Approach and Cluster Filtering) indicates the superiority of the proposed scheme both in terms of robustness against attacks (e.g., ballot-stuffing, bad-mouthing) and computational efficiency.
Development of Robust HTS-SQUID for Non-destructive Inspection System in Unshielded Environment (2014)

Cross-shaped YBa2Cu3O7−x (YBCO) film was overlapped on directly-coupled multi-pickup-coil HTS-dc-SQUID magnetometer in flip-chip configuration as a superconducting shield, and the characterestics of the SQUID were examined in DC and AC magnetic fields. We created slots in the YBCO film and pickup-coil of HTS-SQUID magnetometer for suppression of flux trapping. In low magnetic field environment, we measured the characteristics of the SQUID without and with HTS film. The most of the parameters were same with and without the HTS films, while S1/2 with the HTS film was a bit smaller than that of the bare SQUID. In the DC field, Ic of the HTS-SQUID covered with the HTS film did not change until a DC field over 140 μT was applied to the SQUID, while the bare SQUID's Ic decreased with the increase of the applied DC field. In the AC fields at 10 MHz, the SQUID with the HTS film showed degradation of the parameters such as Vpp and S12 at lower field amplitude than the bare SQUID.
B-SSCT: A Block Sequential Spectrum Sensing Scheme for Cognitive Radio (2011)

Recently, it has been shown that in comparison to the well-known energy detection scheme, the sequential shifted chi-square test (SSCT) is capable of delivering considerable reduction on the average sample number (ASN) while maintaining a comparable detection error performance for spectrum sensi
Characteristics of stainless steel strip cast by twin rolls. (1988)

Experiments on the strip casting of a Type 304 stainless steel have been done by the use of a twin-roll caster with the copper alloy rolls of 400mm diameter and 300mm wide. Cast strips of 120kg with good shape and appearance were obtained with high reproducibility. The casting speed was 17-40m/min, and the length and thickness of the strip were about 30m and O.8-2.3mm, respectively. At an early stage of the casting operation the thickness reduces rapidly, and then approaches a constant value. According to the analysis of heat transfer and thermal expansion of rolls, the early decrease in thickness seems to be caused by the thermal expansion of rolls. The cast strip is not free from defects which should be minimized. The microstructure and segregation of the cast strip have also been inves-tigated. The tensile properties of the cold rolled sheets by this process satisfy those as a Type 304 stainless steel.
The Complete Nucleotide Sequence and Biotype Variability of Papaya leaf distortion mosaic virus (2005)

ABSTRACT The complete nucleotide sequence of the genome of Papaya leaf distortion mosaic virus (PLDMV) was determined. The viral RNA genome of strain LDM (leaf distortion mosaic) comprised 10,153 nucleotides, excluding the poly(A) tail, and contained one long open reading frame encoding a polyprotein of 3,269 amino acids (molecular weight 373,347). The polyprotein contained nine putative proteolytic cleavage sites and some motifs conserved in other potyviral polyproteins with 44 to 50% identities, indicating that PLDMV is a distinct species in the genus Potyvirus. Like the W biotype of Papaya ringspot virus (PRSV), the non-papaya-infecting biotype of PLDMV (PLDMV-C) was found in plants of the family Cucurbitaceae. The coat protein (CP) sequence of PLDMV-C in naturally infected-Trichosanthes bracteata was compared with those of three strains of the P biotype (PLDMV-P), LDM and two additional strains M (mosaic) and YM (yellow mosaic), which are biologically different from each other. The CP sequences of three strains of PLDMV-P share high identities of 95 to 97%, while they share lower identities of 88 to 89% with that of PLDMV-C. Significant changes in hydrophobicity and a deletion of two amino acids at the N-terminal region of the CP of PLDMV-C were observed. The finding of two biotypes of PLDMV implies the possibility that the papaya-infecting biotype evolved from the cucurbitaceae-infecting potyvirus, as has been previously suggested for PRSV. In addition, a similar evolutionary event acquiring infectivity to papaya may arise frequently in viruses in the family Cucurbitaceae.
