Automatic 3D segmentation of ultrasound images using atlas registration and statistical texture prior (2011)

We are developing a molecular image-directed, 3D ultrasound-guided, targeted biopsy system for improved detection of prostate cancer. In this paper, we propose an automatic 3D segmentation method for transrectal ultrasound (TRUS) images, which is based on multi-atlas registration and statistical texture prior. The atlas database includes registered TRUS images from previous patients and their segmented prostate surfaces. Three orthogonal Gabor filter banks are used to extract texture features from each image in the database. Patient-specific Gabor features from the atlas database are used to train kernel support vector machines (KSVMs) and then to segment the prostate image from a new patient. The segmentation method was tested in TRUS data from 5 patients. The average surface distance between our method and manual segmentation is 1.61 ± 0.35 mm, indicating that the atlas-based automatic segmentation method works well and could be used for 3D ultrasound-guided prostate biopsy.
The Storage Space Allocation Problem at a Container Terminal (2017)

Due to the asymmetry between the time required to retrieve a container to vessel and the time required to register a container at the gate, the storage space allocation problem solves the best allocation policy of these containers that minimizes the potential number of gantry movements during the assigning process and the future retrieval process. A decision rule-based heuristic is proposed, and three properties are discovered in this research. Comprehensive numerical experiments show that the proposed heuristic can solve the real-sized instances within a second, making it possible to account for uncertainty because the re-optimization effort is negligible. Moreover, when applying the proposed heuristic to a container yard at the Port of Kaohsiung in Taiwan and considering the extreme cases, the heuristic performs even better when the number of containers increases and still requires less than 1 s to solve these extreme cases. Finally, the proposed heuristic can be applied to different layouts of storage space and various material handling machines.
Characterization of the Oxide Film Obtained by Wet Oxidation of Al-Rich AlGaAs (2012)

We investigate the characteristics of oxide film obtained by wet oxidation of Al x Ga 1- x As with its Al concentration x between 0.55 and 0.99. 300-nm-thick Al x Ga 1- x As grown on GaAs substrate by molecular beam epitaxy is wet-oxidized in a furnace at 410 °C for 120 min. Samples having x greater than 0.8 are confirmed to be oxidized from their observation, examined by X-ray diffraction showing the vanished crystallographic diffraction peaks. Scanning electron microscopy, X-ray reflectivity, and spectroscopic ellipsometry study determines the thickness, density and refractive index of the oxide films.
Extending quality metrics to full luminance range images (2008)

Many quality metrics take as input gamma corrected images and assume that pixel code values are scaled perceptually uniform. Although this is a valid assumption for darker displays operating in the luminance range typical for CRT displays (from 0.1 to 80 cd/m<sup>2</sup>), it is no longer true for much brighter LCD displays (typically up to 500 cd/m<sup>2</sup>), plasma displays (small regions up to 1000 cd/m<sup>2</sup>) and HDR displays (up to 3000 cd/m<sup>2</sup>). The distortions that are barely visible on dark displays become clearly noticeable when shown on much brighter displays. To estimate quality of images shown on bright displays, we propose a straightforward extension to the popular quality metrics, such as PSNR and SSIM, that makes them capable of handling all luminance levels visible to the human eye without altering their results for typical CRT display luminance levels. Such extended quality metrics can be used to estimate quality of high dynamic range (HDR) images as well as account for display brightness.
A personal computer based design system for profiling overhead lines (1988)

An efficient personal computer-based tool is presented for the mechanical dimensioning of overhead distribution lines. The design system includes routines for calculating the strengths of poles and conductors, calculating the sag curves, dimensioning the poles, cross-arms and stays and for the scaled graphical output of ground and line profiles. The design method also includes a simple heuristic optimisation algorithm for minimising the heights of poles within the safety and technical constraints. The programs are interactive and are equipped with graphic facilities. The experience of using the design method in practical design work has been very positive. Savings have been made both in the costs of building the line and in the time required for the design process compared with manual methods.
Cardiomyopathy and other chronic toxic effects induced in rabbits by doxorubicin and possible prevention by coenzyme Q10. (1981)

Cumulative dose-dependent toxic effects, particularly cardiomyopathy, induced by doxorubicin and the possible prevention by coenzyme Q10 (CoQ10) were studied in rabbits. In rabbits given doxorubicin alone, there was considerable body weight loss, alopecia, pancytopenia, significant increase in serum creatine phosphokinase and LDH, and ECG changes characterized by tachycardia, flat and inverted T wave, the premature ventricular contractions. In rabbits given doxorubicin plus CoQ10, the only change was pancytopenia. In rabbits treated with doxorubicin alone, the most prominent histologic changes were observed in mitochondria of myocytes, and these changes were characterized by loss of outer membrane, disarrangement of cristae, and formation of numerous concentric lamellae. In addition to mitochondrial changes, there were numerous vacuolizations and extensive depositions of both electron-dense and membranous laminated bodies in the sarcoplasm and disarrangement of Z-band and filamentous changes of myofibrils. Numerous vacuolizations in the capillary endothelial cytoplasm in the myocardium were also conspicuous. On the other hand, few significant morphologic changes were seen in the nuclei of myocytes. There were few ECG and histopathologic changes in rabbits treated with both doxorubicin and CoQ10. These findings suggest that the cardiomyopathy of doxorubicin may be prevented or is at least inhibited by CoQ10. The mechanisms of both doxorubicin-induced cardiomyopathy and its prevention by CoQ10 are discussed.
Effect of nitric oxide synthase inhibition on blood flow after retinal ischemia in cats. (1995)

Nitric oxide appears to be a significant factor in the regulation of uveal circulation and may contribute to the regulation of retinal, but not choroidal, blood flow after ischemia. The authors could not detect a difference in outcome by electroretinography with or without nitric oxide synthase inhibition.
beta-lactamase from Streptomyces cacaoi. Purification and properties. (1981)

A beta-lactamase was purified to an apparently homogeneous state from Streptomyces cacaoi. The molecular weight calculated from the mobility in sodium dodecyl sulfate polyacrylamide gel electrophoresis was 34,000. pI was 4.7 and the optimal pH was 6.5. The optimum temperature was found to be between 40 degrees C and 45 degrees C, but the enzyme lost activity above 50 degrees C. N-Bromosuccinimide was the strongest inhibitor among the reagents tested, followed by iodine. p-Chloromercuribenzoate showed a weak inhibitory effect. Diisopropylfluorophosphate and sodium chloride did not show any inhibitory effect on the enzyme. The beta-lactamase catalyzed the hydrolysis of methicillin and cloxacillin at two-thirds to one-third the rate of benzylpenicillin. On the other hand, the enzyme hydrolyzed cephalosporins and 7-methoxycephalosporin only slowly. With benzylpenicillin as a substrate, the Km increased sharply with decreasing pH and the pK alpha estimated from the Km versus pH curve was 6.5 to 7.0. In contrast, with cloxacillin as a substrate, the Km showed a minimum at pH 7.5. The Vmax changed with pH in a bell-shaped curve in the case of benzylpenicillin, but the Vmax for cloxacillin changed only within a small range. In addition, the ratio of the hydrolysis rate of benzylpenicillin and cloxacillin at 30 degrees C and 20 degrees C (V30 degrees/V20 degrees) was found to be 1.23 and 1.55, respectively. These results indicate that the S. cacaoi beta-lactamase behaves differently toward benzylpenicillin and cloxacillin, although both are penicillins. S. cacaoi seems to release beta-lactamase into the culture medium soon after its biosynthesis without retaining it in the membrane and the soluble fraction. The possible relationships between beta-lactamases from Streptomyces and those from pathogenic bacteria are discussed.
Putative Immunodominant Human Immunodeficiency Virus-Specific CD8<sup>+</sup>T-Cell Responses Cannot Be Predicted by Major Histocompatibility Complex Class I Haplotype (2000)

Recent studies of human immunodeficiency virus (HIV)-specific CD8(+) T cells have focused on responses to single, usually HLA-A2-restricted epitopes as surrogate measures of the overall response to HIV. However, the assumption that a response to one epitope is representative of the total response is unconfirmed. Here we assess epitope immunodominance and HIV-specific CD8(+) T-cell response complexity using cytokine flow cytometry to examine CD8(+) T-cell responses in 11 HLA-A2(+) HIV(+) individuals. Initial studies demonstrated that only 4 of 11 patients recognized the putative immunodominant HLA-A2-restricted p17 epitope SLYNTVATL, suggesting that the remaining subjects might lack significant HIV-specific CD8(+) T-cell responses. However, five of six SLYNTVATL nonresponders recognized other HIV epitopes, and two of four SLYNTVATL responders had greater responses to HIV peptides restricted by other class I alleles. In several individuals, no HLA-A2-restricted epitopes were recognized, but CD8(+) T-cell responses were detected to epitopes restricted by other HLA class I alleles. These data indicate that an individual's overall CD8(+) T-cell response to HIV is not adequately represented by the response to a single epitope and that individual major histocompatibility complex class I alleles do not predict an immunodominant response restricted by that allele. Accurate quantification of total HIV-specific CD8(+) T-cell responses will require assessment of the response to all possible epitopes.
Alloy theory of the intermediate valence state: Application to europium metal (1976)

A microscopic theory for the intermediate valence state is given, containing no phenomenological parameters. The intermediate state is considered as an alloy of constituents of different integral valence and treated in the virtual-crystal approximation. The theory is applied to europium metal, resulting in a continuous change of valence, starting at 180 kbar and being completed at 350 kbar. The calculated pressured-volume relation resembles those found for some rare-earth monochalcogenides.
Step and flash imprint lithography template fabrication for emerging market applications (2007)

The Step and Flash Imprint Lithography (S-FIL<sup>TM</sup>) process uses field-to-field drop dispensing of UV curable liquids for step and repeat patterning for applications where high-resolution mix-and-match overlay is desired. Several applications, including patterned media, photonic crystals and wire grid polarizers, are better served by a patterning process that prints the full wafer since alignment requirements are not so stringent. In this paper, a methodology for creating high resolution thin templates for full wafer (or disk) imprinting is described. The methods have been applied toward the imprinting of both photonic crystal and patterned media devices using a large area printing tool developed around the S-FIL process.
Efficacy of tylosin tablets for the treatment of pyoderma due to Staphylococcus intermedius infection in dogs. (1994)

Tylosin tablets (20 mg/kg, q12h) were administered orally to 21 dogs with superficial or deep staphylococcal pyodermas. Response to therapy was excellent in 90.5% of the dogs, and in vitro susceptibility testing correlated perfectly with therapeutic response. Duration of therapy varied from 17 to 91 days, with an average of 33 days. Relapses occurred in 28.6% of the dogs within a three-month period. No side effects were reported. Under the conditions of the study, tylosin was an effective and safe antibiotic for the treatment of staphylococcal pyoderma in dogs.
The Health Professions Stress Inventory (1988)

An instrument was developed to assess the levels and sources of stress experienced by health professionals. Based on a review of the literature, the Health Professions Stress Inventory was constructed and administered via a mail questionnaire to a large group of practicing physicians, pharmacists, and nurses. Data analyses indicated that the inventory possessed suitable internal consistency, as measured by Cronbach's alpha coefficient. Scores also were correlated significantly with scores on Lyons' tension index. The inventory shows internal consistency and concurrent validity. It should be useful in assessing the relative stress perceived in health professions.
Low-Temperature Microscopic Photoluminescence Images of Epitaxially Laterally Overgrown GaN (2001)

Microscopic photoluminescence (PL) measurement has been carried out on epitaxially laterally overgrown (ELO) GaN with a spatial resolution of 0.3 µm at 15 K. PL emissions ascribed to free excitons ( E XA ) and excitons bound to donors ( D 0 X ) were clearly discriminated. In a plan-view observation, these band-edge emissions from a region above a SiO 2 mask are twice as large as those from a region above the opening between masks. In a cross-sectional observation, the emission intensity at 3.494 eV ascribed to E XA increased along the growth direction. An intense emission at 3.487 eV ascribed to D 0 X was observed above the SiO 2 mask within a distance of 8 µm from the SiO 2 mask.
Growth of thin films by laser-induced evaporation (1988)

Abstract Among the various material growth techniques, physical vapor deposition of thin films encompasses many experimental forms. They can be categorized into equilibrium and none-quilibrium processes according to the ways in which the source materials are vaporized. Equilibrium process is typified by thermal evaporation including the conventional resistive heating, the more elaborate e-beam evaporation. as well as molecular beam epitaxy (MBE). Nonequilibrium processes include sputtering and many of its derivative forms such as ion beam deposition. In comparison with these techniques, thin-film deposition by laser evaporation is less well known and does not fall cleanly into either category. Depending on the laserconditions, the evaporation process can be either thermal, nonthermal, or a mixture of the two.
Relevance of low titers of cryoglobulins and cold-agglutinins in patients with isolated Raynaud phenomenon. (2001)

The detection of low titers of cold agglutinins in patients with isolated Raynaud phenomenon is of no diagnostic or prognostic relevance.
Power routing scheme with dual operating modes: two-way Wilkinson divider and one-way signal path (2004)

A reconfigurable power-dividing scheme has been developed, employing coupled line couplers and mode control switches. Depending on the operating conditions of the switches, it provides two different operating states: two-way Wilkinson equal-split power divider or one-way signal path, which directs all input power to one output port. Input and output matching conditions at both operating modes were accomplished by utilising appropriate even- and odd-mode characteristic impedances of the coupled line coupler.
Crystal structures and magnetic properties of rare earth tantalates RE<sub>3</sub>TaO<sub>7</sub>(RE = rare earths) (2004)

The crystal structures and magnetic properties of rare earth tantalates RE 3 TaO 7 (RE = rare earths) are reported.Their crystal structures were grouped into three types: La 3 NbO 7 -type, Y 3 TaO 7 -type, and defect-fluorite-type.For the Ho 3 TaO 7 compound, two different phases (Y 3 TaO 7 -type and defect-fluoritetype) were prepared.At around room temperature, Nd 3 TaO 7 was found to transform from the Y 3 TaO 7 -type phase to La 3 NbO 7 -type phase with increasing temperature.Temperature dependences of the magnetic susceptibilities and specific heats indicated that the Nd and Tb compounds undergo a 'two-step' antiferromagnetic transition with separate ordering of ions on different crystallographic sites below 2.6 and 3.6 K, respectively.The Dy 3+ ion was found to be in an antiferromagnetic state below 2.3 K.The Ho 3 TaO 7 with the Y 3 TaO 7 -type structure showed an antiferromagnetic-like transition, while no magnetic ordering was observed down to 1.8 K for the defect-fluorite-type Ho 3 TaO 7 .
Alteration of follicle regulatory protein levels in human reproductive disorders: anovulation. (1987)

Recently, a follicle regulatory protein was identified that suppresses ovarian response to gonadotropins. In this study, the serum levels of follicle regulatory protein were measured in five groups of women: reproductive age undergoing oophorectomy (N = 10), postmenopausal (N = 10), ovulatory (N = 13), anovulatory (N = 16), and anovulatory receiving clomiphene citrate therapy (N = 14). Follicle regulatory protein-related immunoreactivity was measured by a competitive enzyme-linked immunosorbent assay, while peripheral estradiol and progesterone levels were determined by established radioimmunoassay. Concentration of follicle regulatory protein in serum in all ovariectomized patients decreased significantly from preoperative levels. The postmenopausal women had significantly lower follicle regulatory protein levels than did ovulatory and anovulatory women. Patients with low levels of serum estradiol in the early follicular phase exhibited either significantly elevated or suppressed follicle regulatory protein levels compared with patients with normal estradiol concentrations, suggesting two different etiologies for ovarian dysfunction. Eleven to 12 and 22-23 days after the onset of the last menstrual period, patients with elevated follicle regulatory protein levels were found to be anovulatory. These observations suggest that elevated intraovarian levels of follicle regulatory protein may cause a disruption of follicular maturation that leads to anovulation and, in some cases, to resistance to clomiphene citrate therapy.
Facilitating Exploration of Unfamiliar Source Code by Providing 21/2D Visualizations of Dynamic Call Graphs (2007)

For modifying functionality of legacy software systems developers often need to work within millions of lines of unfamiliar code. In this paper we propose a concept that exploits dynamic call graphs for (a) identifying code parts that implement the functionality to be modified and (b) guiding developers while navigating from one source code file to another. The proposed concept is implemented within a tool for analyzing complex C/C++ software systems and has been tested on various million LOC systems. The tool provides a visualization front-end that permits developers to explore the system implementation on 3 levels of abstraction: (I) source code, (2) function interaction, and (3) module interaction. A 21/2D visualization view exploits perspective distortion for displaying both detailed and context information on Junctions and modules, by this, supporting developers during their comprehension tasks.
Principal Component Analysis of the T Wave and Prediction of Cardiovascular Mortality in American Indians (2002)

Abnormalities of repolarization measured by PCA of the T-wave loop predict CV death in men and women, supporting use of PCA for quantifying repolarization abnormalities.
The Dissolution of Scales in Oilfield Systems (1985)

Abstract The phenomenon of scale formation has been experienced by generations of different races whenever water has been used. It was formed in Roman aqueducts and canals and is also found in the present day in the most modern oil production operations. The most commonly found scales in this industry are the carbonate and sulphate salts of calcium, barium and strontium which can be encountered from the reservoir rock itself all the way through the complete process train to the oil exporting system. It can therefore be appreciated that considerable decreases in efficiency of equipment and reservoir production can result from this. The need to maintain high rates of oil production makes this a serious problem and remedial action is desirable. This can be in the form of problem and remedial action is desirable. This can be in the form of inhibition to prevent scale formation, or, where scale is already present, removal is required. This paper outlines the mechanisms of scaling and the principles of scale dissolution using sequestrants. Details of treatment techniques, especially in downhole situations, are also presented.
New functional zonation in the ovary as shown by immunohistochemistry of luteinizing hormone receptor (1992)

Monoclonal anti-LH receptor antibodies were used to study receptor distribution in the various structures of porcine ovary. Primordial and primary follicles were not labeled. Immunoreactivity appeared on the thecal cells of secondary follicles of approximately 100-200 microns in diameter. In large antral follicles and preovulatory follicles granulosa cells were also labeled, whereas two zones were observed in the theca interna. The region close to the lamina basalis (approximately 1/3 of the thecal cells) appeared devoid of LH receptors, whereas a strong labeling was observed on the most external region. Thecal cells were also labeled in atretic follicles. There was no labeling of the oocyte. In cyclic corpora lutea only the most external cells, probably of thecal origin, were stained. The most abundant cells, of granulosa origin, were not labeled. In the interstitium few cells were immunolabeled; they proceeded either from remnants of atretic follicles or existed as groups of isolated cells. Thus both the theca interna of preovulatory follicles and the corpus luteum are heterogenous structures composed of two zones of which only one is directly responsive to LH. No LH immunoactivity could be detected in nontarget organs (liver, lung, thyroid gland, small intestine, fallopian tube, and uterus).
Visualization for University Brand Image Clustering by Simple Topic Model (2016)

Bayesian inference is widely used in various application fields such as topic extraction. In the paper, we present our developed simple topic model visualization tool and as its example, we show university brand image clustering. When high school students select a university, their university choice greatly depends on their universities' brand images. Then the university public relations section needs the survey of the brand images. The clustering results is so helpful for the public relations section to make the publicity strategy. We conducted the university clustering with our developed visualization tool. The paper shows that the visualization has great potential to identify whether the Markov chain reaches the equilibrium states and evaluate the burn-in period.
