Storytelling with digital photographs (2000)

Photographs play a central role in many types of informal storytelling. This paper describes an easy-to-use device that enables digital photos to be used in a manner similar to print photos for sharing personal stories. A portable form factor combined with a novel interface supports local sharing like a conventional photo album as well as recording of stories that can be sent to distant friends and relatives. User tests validate the design and reveal that people alternate between “photo-driven” and “story-driven” strategies when telling stories about their photos.
Increase of Coercivity and Composition Distribution in Fluoride-Diffused NdFeB Sintered Magnets Treated by Fluoride Solutions (2010)

Rare-earth and fluorine were diffused along grain boundaries in NdFeB sintered magnets during heat treatment after rare-earth fluoride liquid coating. In the case of Dy fluoride coating, the coercivity for NdFeB sintered magnets with a thickness of 1 mm after the diffusion was increased from 0.80 MA/m to 1.13 MA/m (41%) with remanence reduction of 0.6%. Segregations for Dy atoms near the grain boundaries and fluorine atoms at the grain boundary were found by TEM observations. The increase of coercivity per the weight of the rare-earth fluorides has a correlation with the anisotropy field of the RE <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sub> Fe <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">14</sub> B (RE is rare-earth elements). Furthermore, the Dy quantity required for the observed increase of coercivity can be reduced to 1/3 compared to the previous NdFeB sintered magnets using the fluoride coating and diffusion process.
A simple, specific, and highly sensitive blocking enzyme-linked immunosorbent assay for detection of antibodies to bovine herpesvirus 1 (1994)

By using a monoclonal antibody directed against an epitope located on glycoprotein B of bovine herpesvirus 1 (BHV1), a simple, convenient blocking enzyme-linked immunosorbent assay (ELISA) which combines a high sensitivity with a low false-positive rate has been developed. The test can be performed at low variance on undiluted bovine serum samples. The epitope on glycoprotein B appears to be conserved, because it could be detected by immunostaining in all of 160 BHV1 isolates originating from 10 countries. In testing 215 anti-BHV1 antibody-negative and 179 anti-BHV1 antibody-positive serum samples, specificity and sensitivity were 0.96 and 0.99, respectively. This blocking ELISA is superior to a commercially available indirect ELISA and to the 24-h virus neutralization test in detecting low antibody levels in serum. In addition, this blocking ELISA is able to detect specific antibodies in serum as early as 7 days postinfection. To minimize any risk of introducing latent BHV1 carriers among noninfected cattle, this blocking ELISA would be, in our opinion, the test of choice.
Systematic study of high-frequency ultrasonic transducer design for laser-scanning photoacoustic ophthalmoscopy (2014)

Photoacoustic ophthalmoscopy (PAOM) is a high-resolution in vivo imaging modality that is capable of providing specific optical absorption information for the retina. A high-frequency ultrasonic transducer is one of the key components in PAOM, which is in contact with the eyelid through coupling gel during imaging. The ultrasonic transducer plays a crucial role in determining the image quality affected by parameters such as spatial resolution, signal-to-noise ratio, and field of view. In this paper, we present the results of a systematic study on a high-frequency ultrasonic transducer design for PAOM. The design includes piezoelectric material selection, frequency selection, and the fabrication process. Transducers of various designs were successfully applied for capturing images of biological samples in vivo. The performances of these designs are compared and evaluated.
Watermarking electronic text documents containing justified paragraphs and irregular line spacing (2004)

In this paper, we propose a new method for watermarking electronic text documents that contain justified paragraphs and irregular line spacing. The proposed method uses a spread-spectrum technique to combat the effects of irregular word or line spacing. It also uses a BCH (Bose-Chaudhuri-Hocquenghem) error coding technique to protect the payload from the noise resulting from the printing and scanning process. Watermark embedding in a justified paragraph is achieved by slightly increasing or decreasing the spaces between words according to the value of the corresponding watermark bit. Similarly, watermark embedding in a text document with variable line spacing is achieved by slightly increasing or decreasing the distance between any two adjacent lines according to the value of the watermark bit. Detecting the watermark is achieved by measuring the spaces between the words or the lines and correlating them with the spreading sequence. In this paper, we present an implementation of the proposed algorithm and discuss its simulation results.
Serum Procalcitonin Level and Other Biological Markers to Distinguish Between Bacterial and Aseptic Meningitis in Children (2008)

The PCT level is a strong predictor for distinguishing between bacterial and aseptic meningitis in children in the emergency department. Its combination with other parameters in an effective clinical decision rule could be helpful.
An adaptive first-order polarization-mode dispersion compensation system aided by polarization scrambling: theory and demonstration (2000)

An adaptive polarization-mode dispersion (PMD) compensation system has been developed to cancel the effects of first-order PMD by producing a complementary PMD vector in the receiver. Control parameters for the PMD compensation system comprised of a polarization controller and a PMD emulator are derived from the nonreturn-to-zero (NRZ) signal in the channel to be compensated. Estimates of the link's differential group delay (DGD) and principal states of polarization (PSPs) based on this signal are reliable when the signal power is equally split between the link's two PSP's; however this condition cannot be assumed. To meet this requirement, we scramble the state of polarization (SOP) of the input signal at a rate much greater than the response time of the PMD monitor signal so that each sample represents many different SOP alignments. This approach allows the effective cancellation of the first-order PMD effects within an optical fiber channel.
Signal Processing to Reduce the Effect of Gear Dynamics (2020)

An improved conditioning monitoring technique is provided for rotating components in gearboxes that account for gear system dynamics. A rotation rate for the component is generated from vibration data by estimating the rotation rate based on a tachometer measurement of another shaft and the shaft ratio. This estimated rotation rate is used, together with the known configuration of the component, to estimate a known gear mesh frequency of the component. By filtering for a range of frequencies around the gear mesh frequency based on variation in the shaft rate, the gear mesh frequency can be determined, and from that signal, an actual rotation rate for the component can be determined. The exact rate can then be used in deriving an analytic vibration spectrum for the component that is not degraded due to gear system dynamics effects. Further, this allows the calculation of the gearbox transfer function.
Hall Thruster with an External Acceleration Zone (2005)

This work presents a study of the external acceleration operating mode of a low-power linear-geometry Hall thruster. Measurements are reported of the performance and of the near exit plane ion velocity field in a high vacuum environment. Thrust and efficiency were measured at Stanford University, while ion velocities were measured in a similar vacuum environment at the Air Force Research Laboratory, using laser induced fluorescence of the excited state xenon ionic transition at 834.7 nm. Velocities were measured primarily in the near field, from the channel exit plane to a downstream distance of 3 cm. Both axial and cross-field (along the electron Hall current direction) component velocities were measured. The results presented here, combined with those of previous studies, highlight the high sensitivity of the electron mobility to discharge properties inside and outside of the channel, such as background gas density, wall material, or magnetic field strength. When operated at low background pressure, this particular linear Hall discharge creates an ion accelerating electrostatic field that is 0.5 – 2 cm downstream of the exit plane, well outside of the channel. This interesting mode of operation is attributed to the reduced electron impendence due to wall current at the terminating end of the electron drift. In this particular design, the consequence is a reduced level of performance, because of the non-ideal magnetic field configuration in the acceleration region. However, it suggests the possibility of new opportunities towards developing so-called wall-less Hall thruster, which have the promise of lower wall erosion. I.
Use of 16S rRNA, 23S rRNA, and <i>gyrB</i> Gene Sequence Analysis To Determine Phylogenetic Relationships of <i>Bacillus cereus</i> Group Microorganisms (2004)

In order to determine if variations in rRNA sequence could be used for discrimination of the members of the Bacillus cereus group, we analyzed 183 16S rRNA and 74 23S rRNA sequences for all species in the B. cereus group. We also analyzed 30 gyrB sequences for B. cereus group strains with published 16S rRNA sequences. Our findings indicated that the three most common species of the B. cereus group, B. cereus, Bacillus thuringiensis, and Bacillus mycoides, were each heterogeneous in all three gene sequences, while all analyzed strains of Bacillus anthracis were found to be homogeneous. Based on analysis of 16S and 23S rRNA sequence variations, the microorganisms within the B. cereus group were divided into seven subgroups, Anthracis, Cereus A and B, Thuringiensis A and B, and Mycoides A and B, and these seven subgroups were further organized into two distinct clusters. This classification of the B. cereus group conflicts with current taxonomic groupings, which are based on phenotypic traits. The presence of B. cereus strains in six of the seven subgroups and the presence of B. thuringiensis strains in three of the subgroups do not support the proposed unification of B. cereus and B. thuringiensis into one species. Analysis of the available phenotypic data for the strains included in this study revealed phenotypic traits that may be characteristic of several of the subgroups. Finally, our results demonstrated that rRNA and gyrB sequences may be used for discriminating B. anthracis from other microorganisms in the B. cereus group.
Visualizing Sentiment Divergence Dynamics in Social Media Through SocialHelix (2013)

Social media allow people to express and propagate different opinions, in which people’s sentiments to a subject often diverge when their opinions conflict. An intuitive visualization that allows for unfolding the process of sentiment divergence from the rich and massive social media data will have far-reaching impact in various domains including social, political and economic. In this poster, we propose a visualization system, SocialHelix, to achieve this goal. SocialHelix is a novel visual design which enables users to detect and trace occurring in social media, and to understand when and why conflicts occurred and how they evolved among different social groups. We demonstrate the effectiveness and usefulness of SocialHelix by conducting in-depth case studies based on Twitter data regarding to the national political debates.
Association of prostate cancer with vitamin D receptor haplotypes in African-Americans. (1998)

In previous studies, allelic variation in the 3' end of the vitamin D receptor gene was associated with increased risk of prostate cancer in white men. Several polymorphisms, including a BsmI restriction site and a poly(A) microsatellite, can be used interchangeably to mark the unidentified locus in whites. In African-Americans, however, these markers are not interchangeable, due to weaker linkage disequilibrium in this genomic region in this population. Here, we genotyped both the BsmI and poly(A) markers for 151 African-American prostate cancer cases (102 localized and 49 advanced) and 174 African-American male controls from a large epidemiological cohort. A direct haplotyping procedure was devised to determine BsmI/poly(A) haplotypes for double heterozygotes so that haplotypes could be used as allelic markers in standard logistic regression analyses. Using BsmI alone, b alleles were associated with a 2-fold decrease in risk of advanced prostate cancer. The association was, however, confined to haplotypes carrying a long (L) allele of the poly(A) microsatellite. BL and bL haplotypes were associated with increased and decreased risk, respectively, whereas neither BS nor bS haplotypes were associated with prostate cancer risk. An allelic variant that confers increased risk of advanced prostate cancer appears to be associated with the BsmI/poly(A) BL haplotype in African-Americans.
2.5 Gbit/s polycrystalline germanium-on-silicon photodetector operating from 1.3 to 1.55 μm (2003)

We report on a fast polycrystalline germanium-on-silicon heterojunction photodetector for the near-infrared. The device exhibits a pulse response faster than 200 ps, allowing operation at 2.5 Gbit/s as testified by open eye diagrams. This polycrystalline device, with responsivities of 16 and 5 mA/W at 1.3 and 1.55 μm, respectively, and dark currents of 1 mA/cm2, is entirely integrable on standard silicon electronics and is an appealing low-cost candidate for fiber-to-the-home communication networks.
Selective and Gram-Scale Synthesis of [6]Cycloparaphenylene (2015)

A selective, practical, and large-scale synthesis of [6]cycloparaphenylene, the second smallest cycloparaphenylene to be synthesized, was achieved in nine steps starting from commercially available 1,4-dibromobenzene and 4′-bromobiphenyl-4-ol. The key intermediate, <i>cis</i>-1,4-(4-bromophenyl)-1,4-bis(triethylsiloxy)cyclohexa-2,5-diene, was prepared on a large scale (>20 g) and was selectively dimerized to form a cyclic precursor of [6]cycloparaphenylene by platinum-mediated assembly and subsequent reductive elimination. Deprotection of the triethylsilyl group and subsequent tetrachlorostannic acid (H<sub>2</sub>SnCl<sub>4</sub>)-mediated reductive aromatization gave [6]cycloparaphenylene in 23% overall yield from the commercially available substrates on gram scale.
Synthesis of 1- and 2-substituted indazoles as anthelmintic agents (1976)

Selective synthesis of 1- and 2-acyl-, alkoxycarbonyl-, and carbamoylindazoles are described. Spectroscopic data which were the basis for structural assignments are presented. These compounds, particularly methyl 2H-indazole-2-carboxylate and N-heptyl-N-methyl-2H-indazole-2-carboxamide, lack the spectrum of anthelmintic activity of the benzimidazole and benzotriazole anthelmintics to which they are structurally related.
MAGNETICALLY SUSPENDED CENTRIFUGAL BLOOD PUMP WITH A RADIAL MAGNETIC DRIVER (2004)

[Objective] Magnetic bearing system can offer long term durability for centrifugal blood pumps by suspending the impeller without mechanical contact. In addition, elimination of mechanical contact reduces occurrence of hemolysis and thrombus formation that usually occurs around the contact bearings. To achieve acceptable degree of stability and stiffness, however, complex control system is required. The overall system size increases with higher power consumption and increased heat generation. A new concept magnetic bearing system developed in our group addresses such a problem. [Method]A vertically magnetized permanent magnet ring that was contained inside the u-shaped iron-core was embedded at the outer edge of the rotor, while four electro-magnets, one pair in the X and Y axis each, were fixed in the stationary outer pump housing. Two gap sensors were used to continuously monitor the spacing between the rotor and pump housing to actively control radial eccentricity with two degree of freedom. The z-axis control was obtained passively with the permanent magnet ring and iron-core coupling mechanism. [Results and Conclusion] The centrifugal blood pump was assembled using the prototype magnetic bearing system (Π75mm, height 8mm). The impeller was driven using a radial magnetic coupling system. No-load and still condition, bearing power consumption was 0.03W, while it required 1.3W at 100 mmHg, 5 L/min. The stiffness in z direction was 15 N/mm. The compact magnetic bearing system requires low power, allowing high stiffness and controllability and thus suitable for implantable continuous flow pumps.
White-light density pseudocolor encoding with three primary colors (1984)

Describes a technique for generating density pseudocolor encoding with three primary colors using a white-light optical processor. Spatial encodings are made with positive, negative, and a product of positive and negative photographic-image transparencies, and the pseudocoloring is obtained by color filtering of the smeared Fourier spectra. The technique is simple, versatile, and economical to operate and offers a wide range of applications. Since coherent sources are not utilized, the color coded image is free from coherent artifact noise. Experimental demonstrations of this density pseudocolor encoder are provided.

Residual Water Suppression Using the Squared Eigenfunctions of the Schrödinger Operator (2019)

Water suppression, in proton magnetic resonance spectroscopy (MRS) using post-processing techniques, is very challenging due to the large amplitude of the water line, which shadows the metabolic peaks with small amplitudes and complicates their quantification. In addition, the peak-shaped structure of these spectra and the relatively small number of data points representing them makes the suppression process more cumbersome. In this paper, a post-processing water suppression technique based on the Schrödinger operator is proposed. The method is based on the decomposition of the input MRS spectrum, using the squared eigenfunctions of a semi-classical Schrödinger operator. The proposed approach proceeds in three steps: first, the water peak is estimated using an optimal choice of the value of h to reconstruct the MRS spectrum with a minimum number of eigenfunctions. Second, these estimated eigenfunctions are further refined to ensure that they only represent the water line with no contribution from the metabolite peaks. Finally, the estimated water peak is subtracted from the input MRS spectrum. The proposed method is tested on simulated in vitro and real in vivo MRS data and compared with the Hankel-Lanczos singular value decomposition with partial reorthogonalization (HLSVD-PRO) method. The results obtained show that the semi-classical signal analysis (SCSA) performs comparably to the HLSVD-PRO in accurately suppressing the water peak.

Effect of dietary L-carnitine on growth performance and body composition in nursery and growing-finishing pigs. (2001)

Two experiments were conducted to determine the effect of dietary L-carnitine on growth performance and carcass composition of nursery and growing-finishing pigs. In Exp. 1,216 weanling pigs (initially 4.9 kg and 19 to 23 d of age) were used in a 35-d growth trial. Pigs were blocked by weight in a randomized complete block design (six pigs per pen and six pens per treatment). Four barrows and four gilts were used to determine initial carcass composition. L-Carnitine replaced ground corn in the control diets to provide 250, 500, 750, 1,000, or 1,250 ppm. On d 35, three barrows and three gilts per treatment (one pig/block) were killed to provide carcass compositions. L-Carnitine had no effect (P > 0.10) on growth, percentages of carcass CP and lipid, or daily protein accretion. However, daily lipid accretion tended to decrease and then return to values similar to those for control pigs (quadratic P < 0.10) with increasing dietary L-carnitine. In Exp. 2, 96 crossbred pigs (initially 34.0 kg BW) were used to investigate the effect of increasing dietary L-carnitine in growing-finishing pigs. Pigs (48 barrows and 48 gilts) were blocked by weight and sex in a randomized complete block design (two pigs/pen and eight pens/treatment). Dietary L-carnitine replaced cornstarch in the control diet to provide 25, 50, 75, 100, and 125 ppm in grower (34 to 56.7 kg; 1.0% lysine) and finisher (56.7 to 103 kg; 0.80% lysine) diets. At 103 kg, one pig/pen was slaughtered, and standard carcass measurements were obtained. Dietary L-carnitine did not influence growth performance (P > 0.10). However, increasing dietary carnitine decreased average and tenth-rib back-fat (quadratic, P < 0.10 and 0.05), and increased percentage lean and daily CP accretion rate (quadratic, P < 0.05). Break point analysis projected the optimal dosage to be between 49 and 64 ppm of L-carnitine for these carcass traits. It is concluded that dietary carnitine fed during the nursery or growing-finishing phase had no effect on growth performance; however, feeding 49 to 64 ppm of L-carnitine during the growing-finishing phase increased CP accretion and decreased tenth-rib backfat.
