3D heart image reconstruction and visualization with marching cubes algorithm (2016)

Heart image taken using a CT-scan or MRI is a two-dimensional image. Information obtained from these images is very limited and it takes a lot of pictures from various sides to be able to determine the condition of the heart as a whole. This may slow the process of diagnosis of the heart condition of a patient. This study aims to solve these problems by developing a 3D reconstruction system. Some 2D images taken from different sides, and then go through the filtering to remove noise and sharpen images. The result of filtering is reconstructed using surface rendering technique and implementation of Marching Cubes (MC) algorithm. The MC algorithm used is a standard MC with 15 combinations of the cube. The use of 64 images is sufficient provided that it has an average error of 1%. Preprocessing is essential to obtain segmented part of heart from the original cardiac CT-scan images.
Quality of life assessment in patients with cystic fibrosis by means of the Cystic Fibrosis Questionnaire* Avaliação da qualidade de vida de pacientes com fibrose cística por meio do Cystic Fibrosis Questionnaire (2011)

Objective: To assess the quality of life (QoL) of patients with cystic fibrosis (CF) followed at a university referral center for CF. Methods: A cross-sectional study involving application of the Cystic Fibrosis Questionnaire (CFQ) and Shwachman score in CF patients between April of 2008 and June of 2009. Results: The sample consisted of 75 patients. The mean age was 12.5 ± 5.1 years (range, 6.1-26.4 years). The patients were divided into three groups by age in years: group I ( 70 in the social (group I; p = 0.045), respiratory (group II; p = 0.053), and digestive (p = 0.042) domains. In group III, severity did not correlate with QoL. In groups I and II, patients with an FEV 1 < 80% of predicted did not differ from other patients for any CFQ domain. However, in group III, values for the following domains were significantly lower in patients with an FEV1 < 80%: physical (p = 0.012); body image (p = 0.031); respiratory (p = 0.023), emotional (p = 0.041); and social role (p = 0.024). Conclusions: It is important to assess QoL in CF patients, because it can improve treatment compliance.
Kinetics of Thymocyte Subset Development and SelectionRevealed by Cyclosporin A Treatment (1994)

Cyclosporin A (CsA) inhibits the development of mature thymocytes from their CD4+ CD8+ precursors, but may allow autoreactive cells to mature. Using 3-color flow cytometry, we have followed the progressive development of thymocytes, including potentially autoreactive cells, during CsA treatment. Numbers of CD4+ CD8+ CD3high thymocytes dropped immediately, suggesting that the generation of these mature thymocyte precursors, normally dependent upon positive selection, was inhibited by CsA. Numbers of CD4+ CD8- thymocytes also declined rapidly, but CD4 - CD8+ thymocytes were unaffected for 2 days, suggesting that the mature single-positive subsets are not symmetrically derived from a common GsA-sensitive precursor. An exceptional subset of CD8 SP thymocytes, expressing CD45RA, did not respond to CsA for about 10 days, indicating that they are distantly derived from a CsA-sensitive precursor. Apoptosis of TCR-V beta 3 + thymocytes caused by Mtv-6, quantified according to the down-regulation of CD4 and CD8 on immature thymocytes, was partially inhibited by CsA, to maximal effect within 24 hours. This did not, however, facilitate their development into mature thymocytes.
Maximum Daily Point Rainfall in Uganda: A Sample Survey (1971)

In many hydraulic and hydrological problems as well as in the design criteria for certain engineering structures, for example, dams, culverts and storm drainage systems, the prediction of maximum precipitation amounts occurring over short periods of time in a given number of years is of fundamental importance. With certain structures a very high safety factor is necessary and predictions of the maximum precipitation or maximum flood of short duration are based on the physical upper limits of precipitation producing agents, which vary from region to region. Studies based on the maximum limits of concentrated storm rainfall estimate Probable Maximum Precipitation (PMP) by storm maximization techniques. Such studies have been undertaken for East Africa by Sansom (1953) and Lumb (1970).
Genetic Diversity for Resistance to Heterodera glycines Race 5 in Soybean. (1994)

Heterodera glycines is a serious pest of soybean in the United States. Plant introductions 90763 and 424595 are reported to be resistant to H. glycines race 5; however their genetic relationship for resistance is unknown. Crosses between these two lines and the susceptible cultivar Essex were studied in the F, F, and F generations to determine the number of genes involved in inheritance of resistance. The plants were screened using conventional techniques based on the index of parasitism. The data were subjected to analyses using chi-square test to determine goodness of fit between observed and expected genetic ratios. The cross PI 424595 x Essex segregated 1 resistant:63 susceptible in the F generation, which indicated the presence of three recessive genes controlling resistance to race 5. In the cross PI 90763 x Essex, resistance was conditioned by one dominant and two recessive genes. The cross between PI 424595 and PI 90763 segregated into 13 resistant:3 susceptible. The data fit a four-gene model with two recessive and two dominant genes with epistasis. PI 90763 has a dominant gene, whereas PI 424595 has a recessive gene; both share two additional recessive genes for resistance to race 5. This information is important to geneticists and soybean breeders for the development of cultivars resistant to H. glycines.
<i>SpKrl</i>: a direct target of β-catenin regulation required for endoderm differentiation in sea urchin embryos (2001)

Localization of nuclear beta-catenin initiates specification of vegetal fates in sea urchin embryos. We have identified SpKrl, a gene that is activated upon nuclear entry of beta-catenin. SpKrl is upregulated when nuclear beta-catenin activity is increased with LiCl and downregulated in embryos injected with molecules that inhibit beta-catenin nuclear function. LiCl-mediated SpKrl activation is independent of protein synthesis, indicating that SpKrl is a direct target of beat-catenin and TCF. Embryos in which SpKrl translation is inhibited with morpholino antisense oligonucleotides lack endoderm. Conversely, SpKrl mRNA injection rescues some vegetal structures in beta-catenin-deficient embryos. SpKrl negatively regulates expression of the animalizing transcription factor, SpSoxB1. We propose that SpKrl functions in patterning the vegetal domain by suppressing animal regulatory activities.
BRAF and endocrine tumors: mutations are frequent in papillary thyroid carcinomas, rare in endocrine tumors of the gastrointestinal tract and not detected in other endocrine tumors (2004)

The tumorigenesis of sporadic endocrine tumors is still not fully understood. Activating point mutations of the serine/threonine kinase gene BRAF located on 7q34 are found in a wide range of malignancies, with the highest frequency (66%) occurring in malignant melanomas. Melanomas are tumors of neural-crest-derived cells as are medullary thyroid carcinomas, pheochromocytomas and paragangliomas. BRAF has not been examined in endocrine tumors of the diffuse neuroendocrine system or of neural-crest-derived cells. We examined 130 endocrine tumors of the pancreas, parathyroid gland, adrenal medulla, paraganglia, lung and gastrointestinal tract as well as follicular and c-cell-derived thyroid tumors. We found a high rate of V559E mutations in papillary thyroid carcinomas (47%), one V599E mutation in a well-differentiated gastric endocrine carcinoma (malignant carcinoid), but no activating BRAF mutations in all other endocrine tumors examined. These results point towards different pathways in tumorigenesis of endocrine tumors of various localizations and only rare involvement of the MAP kinase (MAPK) pathway in a subset of malignant neuroendocrine tumors.

ROLE OF VISCOSITY ON TRAJECTORY OF LIQUID JETS IN A CROSS-AIRFLOW (2007)

The effect of liquid viscosity on the penetration and trajectory of a jet in a low subsonic cross-airflow was investigated experimentally. An open-loop wind tunnel was used to generate an airstream in a square cross-sectional test section. Liquid was injected downward through a nozzle that was flush with the top inner surface of the test section. A wide range of experimental conditions was achieved by varying the nozzle diameter, momentum flux ratio, and liquid viscosity. The study revealed that viscosity has distinct effects on the initial part of the liquid column and in the jet's far-field stream. It was shown that far from the nozzle exit, the jet's penetration increased initially as the liquid viscosity increased, but a further increase in viscosity reduced the penetration. On the other hand, close to the nozzle exit, although the effect of liquid viscosity was not obvious, it was generally observed that with the exception of the highest viscosity employed here, the jet's penetration decreased as the viscosity increased. An empirical jet trajectory correlation was proposed to account for the combined effects of viscosity, momentum flux ratio, and nozzle diameter.
Fast evaluation of the Coulomb potential for electron densities using multipole accelerated resolution of identity approximation (2003)

A new computational approach is presented that allows for an accurate and efficient treatment of the electronic Coulomb term in density functional methods. This multipole accelerated resolution of identity for J (MARI-J) method partitions the Coulomb interactions into the near- and far-field parts. The calculation of the far-field part is performed by a straightforward application of the multipole expansions and the near-field part is evaluated employing expansion of molecular electron densities in atom-centered auxiliary basis sets (RI-J approximation). Compared to full RI-J calculations, up to 6.5-fold CPU time savings are reported for systems with about 1000 atoms without any significant loss of accuracy. Other multipole-based methods are compared with regard to reduction of the CPU times versus the conventional treatment of the Coulomb term. The MARI-J approach compares favorably and offers speedups approaching two orders of magnitude for molecules with about 400 atoms and more than 5000 basis functions. Our new method shows scalings as favorable as N1.5, where N is the number of basis functions, for a variety of systems including dense three-dimensional molecules. Calculations on molecules with up to 1000 atoms and 7000 to 14 000 basis functions, depending on symmetry, can now be easily performed on single processor work stations. Details of the method implementation in the quantum chemical program TURBOMOLE are discussed.
A Semantic Tag Recommendation Framework for Collaborative Tagging Systems (2011)

In this work we focus on folksonomies. Our goal is to develop techniques that coordinate information processing, by taking advantage of user preferences, in order to automatically produce semantic tag recommendations. To this end, we propose a generalized tag recommendation framework that conveys the semantics of resources according to different user profiles. We present the integration of various models that take into account content, historic values, user preferences and tagging behavior to produce accurate personalized tag recommendations. Based on this information we build several Bayesian models, we evaluate their performance, and we discuss differences in accuracy with respect to semantic matching criteria, and other approaches.
Making Sense of Trajectory Data in Indoor Spaces (2015)

The increasing prevalence of positioning and tracking systems has helped simplify tracking large amounts of, e.g., People moving through buildings or cars traveling on roads, over long periods of time. However, technical limitations of positioning algorithms and traditional sensing infrastructures are likely, especially indoors, to induce errors and biases in the resulting data. In particular, the resulting motion trajectories often do not conform perfectly to the underlying route network. As a consequence, analyses of trajectory sets are impeded by these phenomena, as it becomes hard to identify which route was taken in a particular travel instance or whether two travel instances followed the same route. In this paper, we present a bootstrapping approach and several algorithms to mitigate error biases and related phenomena, focusing on indoor scenarios. In particular, we are able to estimate and iteratively refine an underlying route network from a set of motion trajectories. Secondly, we represent sub trajectories, i.e., Movements on individual elements of the route network, by their median sub trajectory. The resulting aggregated and cleaned-up data set facilitates using further, domain-specific analysis tools. Additionally, it allows to predict the locally occurring expected positioning error biases. This in turn allows improved positioning, e.g., For real-time navigation assistance scenarios. We evaluate the proposed methods using trajectory data from employees at a large hospital complex. In particular, we show that we can reconstruct the hospital's route network accurately, and that we can furthermore extract median sub trajectories for almost all individual corridors. Finally, we illustrate that median trajectories deliver useful deviation maps to learn, and correct for, the expected local biases in positioning.
Vermehrung des Erregers der aviären infektiösen Anämie (CAA) in embryonierten Hühnereiern* (1986)

Summary Propagation of chicken anaemia agent (CAA) in chicken embryos Virulent chicken anaemia agent (CAA) propagated well in chicken embryos when inoculated on the 5th day of embryonic life and harvested 14 days after inoculation. Highest yields of CAA were obtained from the whole embryo. CAA concentrations in embryos, liver, whole yolk sac or yolk, and in the chorioallantoic membrane (CAM) were determined by titration in MDCC‐MSB 1 cell cultures and in day‐old chickens. In whole embryos inoculated with at least 10 3.6 TCID 50 or 10 2.2 chicken ID 50 /dose, respectively, CAA concentrations of 10 5.0 to 10 6.5 TCID 50 /ml, or 10 3.9 to 10 4.8 chicken ID 50 /ml, respectively, were achieved. These titres were at least as high as could be expected in livers from experimentally CAA‐infected chickens. Titres of CAA detected in the embryonic liver were about equal to those of the remaining body, but titres in the CAM or yolk were at least 10‐fold less. The CAA content of the complete yolk sac varied considerably. Pathological changes could never be seen, either in the embryo or in embryonic membranes. Propagation of CAA in chicken embryos as a means is for production of live vaccines discussed. Zusammenfassung Virulentes CAA (“chicken anaemia agent”) vermehrte sich gut im Hühnerembryo, wenn es am 5. Bruttag in den Dottersack inokuliert und 14 Tage p. i. geerntet wurde. Die CAA‐Konzentrationen im ganzen Embryo, in der Leber, im kompletten Dottersack oder im Dotter und in der Chorioallantoismembran (CAM) wurden durch Titrationen in Zellkulturen (MDCC‐MSB 1) oder in Eintagsküken ermittelt. Im ganzen Embryo wurde nach Inokulation von mindestens 10 3,6 TCID 50 bzw. 10 2,3 Küken‐ID 5,0 ein CAA‐Gehalt von 10 5,0 bis 10 6,5 TCID 50 /ml bzw. von 10 3,9 bis 10 4,8 Küken‐ID 50 /ml erzielt. Diese CAA‐Titer waren mindestens ebenso hoch, wie sie in Lebern experimentell infizierter Küken zu erwarten sind. Die CAA‐Titer in der Embryo‐Leber waren etwa ebenso hoch wie im restlichen Embryokörper, die Titer in der CAM und im Eidotter mindestens 10fach niedriger. Der CAA‐Gehalt des kompletten Dottersacks variierte beträchtlich. Pathologische Veränderungen ließen sich weder im Embryo noch an den embryonalen Häuten feststellen. Die Vermehrung von CAA im Hühnerembryo für die Herstellung von Lebendimpfstoffen wird diskutiert.
A Material Handling System Selection Model (1971)

Abstract A technique is presented which can be used to design, or assist in the design of, an integrated materials handling system for a manufacturing facility or a major department of the facility. The developed procedure selects the materials handling equipment to be used to perform a given set of moves in order to miriimize the system's costs associated with the handling, assuming the plant arrangement remains fixed. To demonstrate the selection procedure, an example problem is presented. Since the method is heuristic, no claim of optimality is made.
Patterned and functionalized nanofiber scaffolds in three-dimensional hydrogel constructs enhance neurite outgrowth and directional control (2014)

This work demonstrates the ability to create unique 3D neural tissue constructs using a combined system of hydrogel and nanofiber scaffolding. Importantly, patterned and biofunctionalized nanofiber scaffolds that can control direction and increase length of neurite outgrowth in three-dimensions hold much potential for neural tissue engineering. This approach offers advancements in the development of implantable neural tissue constructs that enable control of neural development and reproduction of neuroanatomical pathways, with the ultimate goal being the achievement of functional neural regeneration.

Further development of the cleanable steel HEPA filter, cost/benefit analysis, and comparison with competing technologies (1997)

We have made further progress in developing a cleanable steel fiber HEPA filter. We fabricated a pleated cylindrical cartridge using commercially available steel fiber media that is made with 1 {mu}m stainless steel fibers and sintered into a sheet form. Test results at the Department of Energy (DOE) Filter Test Station at Oak Ridge show the prototype filter cartridge has 99.99% efficiency for 0.3 {mu}m dioctyl phthalate (DOP) aerosols and a pressure drop of 1.5 inches. Filter loading and cleaning tests using AC Fine dust showed the filter could be repeatedly cleaned using reverse air pulses. Our analysis of commercially optimized filters suggest that cleanable steel HEPA filters need to be made from steel fibers less than 1{mu}m, and preferably 0.5 {mu}m, to meet the standard HEPA filter requirements in production units. We have demonstrated that 0.5 {mu}m steel fibers can be produced using the fiber bundling and drawing process. The 0.5 {mu}m steel fibers are then sintered into small filter samples and tested for efficiency and pressure drop. Test results on the sample showed a penetration of 0.0015 % at 0.3 {mu}m and a pressure drop of 1.15 inches at 6.9 ft/min (3.5 cm/s) velocity. Based on these results, steel fiber media can easily meet the requirements of 0.03 % penetration and 1.0 inch of pressure drop by using less fibers in the media. A cost analysis of the cleanable steel HEPA filter shows that, although the steel HEPA filter costs much more than the standard glass fiber HEPA filter, it has the potential to be very cost effective because of the high disposal costs of contaminated HEPA filters. We estimate that the steel HEPA filter will save an average of $16,000 over its 30 year life. The additional savings from the clean-up costs resulting from ruptured glass HEPA filters during accidents was not included but makes the steel HEPA filter even more cost effective. 33 refs., 28 figs., 1 tab.
