MTA Solubility: A Long Term Study (2005)

The purposes of this long-term study was to assess the amount of soluble material released by Mineral Trioxide Aggregate to a water medium, to determine if the solubility differences between specimens of various water/powder ratio, as demonstrated in a previous study, would be maintained over time, and to measure the pH of the water that was in contact with the specimens. Specimens were processed at 0.28 and 0.33 water/powder ratios, and immersed in water according to the ISO 6876 standard. The specimens were periodically removed to assess salt content release and reimmersed in fresh water. Assay testing was periodically performed over a 78-day period. Results were expressed as Daily Solubility (solubility rate), and Cumulative Solubility. The mathematical projection from Cumulative Solubility to infinite time showed that MTA could solubilize 22.06% at 0.28 water/powder ratio, and 31.095% at 0.33 water/powder ratio of the specimens' mass in regards to their initial dry weight. MTA did maintain a high pH for an extended period of time under these study conditions.
Adaptive strategy for superpixel-based region-growing image segmentation (2017)

This work presents a region-growing image segmentation approach based on superpixel decomposition. From an initial contour-constrained oversegmentation of the input image, the image segmentation is achieved by iteratively merging similar superpixels into regions. This approach raises two key issues: (1) how to compute the similarity between superpixels in order to perform accurate merging and (2) in which order those superpixels must be merged together. In this perspective, we first introduce a robust adaptive multiscale superpixel similarity in which region comparisons are made both at content and common border level. Second, we propose a global merging strategy to efficiently guide the region merging process. Such strategy uses an adaptive merging criterion to ensure that best region aggregations are given highest priorities. This allows the ability to reach a final segmentation into consistent regions with strong boundary adherence. We perform experiments on the BSDS500 image dataset to highlight to which extent our method compares favorably against other well-known image segmentation algorithms. The obtained results demonstrate the promising potential of the proposed approach.
Personalized Genomic Medicine: A Future Prerequisite for the Prevention of Coronary Artery Disease (2006)

Within the next 10-15 years, medicine will be personalized in large part on the basis of the individual's genomic variants. Coronary artery disease remains the number one cause of morbidity and mortality in the Western world and is predicted to become the number one cause worldwide by 2010. It has been stated that treating the risk factors of coronary artery disease has made it a preventable disease that should be eliminated in the 21st century. It is postulated that about 50% of susceptibility to coronary artery disease is genetic, involving known and occult risk factors. Thus, comprehensive prevention will require identification of genetic susceptibility. The recent technology of a chip with 500,000 DNA markers makes genome-wide scanning to identify the genes contributing to coronary artery disease possible. Multislice CT will provide the high-throughput coronary arteriograms required for this research and for prevention in asymptomatic individuals with a family history of heart disease.
Evaluation of Hach Fish Farmer's Water Quality Test Kits for Saline Water (1988)

Abstract Hach Company Fish Farmer's Water Quality Test Kits (Models FF‐2 and FF‐1A) were compared with Standard Methods of analysis by determining dissolved oxygen, carbon dioxide, pH, total alkalinity, total hardness, chloride, total ammonia‐nitrogen, and nitrite nitrogen in waters of 0, 17, and 30 ppt salinity. Results indicate that the kits generally are reliable for making routine water analyses of saline waters for practical aquacultural applications.
Information Extraction in an Optical Character Recognition Context (2020)

In this dissertation, we investigate the effectiveness of information extraction in the presence of Optical Character Recognition (OCR). It is well known that the OCR errors have no effects on general retrieval tasks. This is mainly due to the redundancy of information in textual documents. Our work shows that information extraction task is significantly influenced by OCR errors. Intuitively, this is due to the fact that extraction algorithms rely on a small window of text surrounding the objects to be extracted. We show that extraction methodologies based on the Hidden Markov Models are not robust enough to deal with extraction in this noisy environment. We also show that both precise shallow parsing and fuzzy shallow parsing can be used to increase the recall at the price of a significant drop in the precision. Most of our experimental work deals with the extraction of dates of birth and extraction of postal addresses. Both of these specific extractions are part of general methods of identification of privacy information in textual documents. Privacy information is particularly important when large collections of documents are posted on the Internet.
Role of BIGH3 R124H Mutation in the Diagnosis of Avellino Corneal Dystrophy (2008)

The detection of the R124H BIGH3 mutation confirmed the diagnosis of ACD in the reported families. This is the first study that shows the presence of such mutation in Spain. The authors found the same mutation reported in other countries. In earlier stages, BIGH3 mutation analysis may help to distinguish ACD from GCD, particularly in young patients.
Protective Effects of Nasal Immunization in Mice with Various Kinds of Inactivated Sendai Virus Vaccines (1986)

The immunoprophylactic effects of nasal vaccination with 13 different kinds of inactivated Sendai virus vaccines were compared by contact exposure to infector mice. Efficacies of the vaccines were evaluated on the basis of the presence of virus-infected cells by immunofluorescent examination of the entire respiratory tract, including the nasal mucosa. A single or double inoculations of B-propiolactone (0.5%)-vaccine promoted the infection in the respiratory tract, particularly in the nasal mucosa, whereas three inoculations of B-propiolactone (0.2%)-vaccine provided considerable protection throughout the respiratory tract with only slight development of serum HI titer. Formalin (0.1%)-vaccine and UV irradiated-vaccine strongly protected the nasal mucosa from infection, but did not sufficiently safeguard the lower respiratory tract even with three vaccinations despite adequate development of serum antibody. Nearly complete protection of the entire respiratory tract was induced with six to eight inoculations of a vaccine treated excessively with both UV rays and 1% formalin, without significant development of serum antibody. Out of eight thermal vaccines, five (inactivated at 23 C, 30 C, 37 C and 7 C, and 30 C and 7 C) provided strong protection against infection when inoculated three times. The others inactivated at higher temperatures (37 C, 50 C, or 60 C) were not so protective. High serum HI titers developed, on the whole, with the drop in the temperature required for inactivating the virus. In eight immune mouse groups in which infection was strongly suppressed in the entire respiratory tract, most of the mice harbored less than 50 viral antigen-positive cells in their nasal mucosa in the postexposure period. The number of the cells was assumed to be a useful criterion for evaluation of vaccine efficacy.
LONG-RANGE TRANSPORTATION PLANNING. ACHIEVING GOOD LAND USE PLANNING WITH WORKABLE TRANSPORTATION SYSTEMS AND NETWORKS (1988)

A 50-year plan is proposed that would replace the current 20-year plan for land use planning and take into account not only the growth of the population, but also allowing for future transportation developments.
Malignancy arising in extragonadal endometriosis.A case report and summary of the world literature (1977)

A case of clear cell carcinoma arising in endometriosis of the retroperitoneum is presented. It occurred 5 years after supracervical hysterectomy and bilateral salpingo-oophorectomy and following 4 years of estrogen therapy. The literature concerning malignancy developing in extragonadal endometriosis has been reviewed and is summarized as follows: 1) 45 cases have been compiled, of which 32 were carcinomas and 13 sarcomas; 2) adenocarcinoma was the most common histologic type, although virtually every tumor of müllerian derivation has been described; 3) the typical patient was nulliparous and perimenopausal; 4) the rectovaginal septum was the most common site, and in general the frequency of malignancy in a given site parallels the frequency of endometriosis in that location; 5) simultaneous tumors of the uterus or ovary were present in seven cases (15%); 6) prognosis appeared affected by site and histologic type; 7) a history of prior pelvic irradiation to effect castration was present in three (9%) of the patients with adenocarcinoma; and 8) four (12%) of the patients with adenocarcinoma were subjected to exogenous estrogens or estrogen-secreting ovarian tumors.

Effect of Sodium Hyaluronate on Corneal Wound Healing (1982)

With the development of the use of sodium hyaluronate for endothelial cell protection during anterior segment surgery, we were interested in the effect of sodium hyaluronate on corneal wound healing. Therefore, the following experiment was performed. Corneal incisions were made in both eyes of 14 albino rabbits. Sodium hyaluronate was used to fill the anterior chamber of the test eye, and balanced salt solution was used in the control eye. The wounds were sutured wih 10-0 nylon. On the seventh postoperative day, and strength was measured. After suture removal, the intraocular pressure was raised until the wound burst. Results showed no statistical difference between these and control eye.
The fungal cell wall: Modern concepts of its composition and biological function (2010)

This review deals with the cell wall (CW), a poorly known surface structure of the cell of mycelial fungi. Data are presented concerning (i) isolation techniques and purity control methods securing the absence of the cytoplasm content in the CW fraction and (ii) the chemical composition of the CW. The structural (backbone) and intrastructural components of the CW, such as aminopolysaccharides, α- and β-glucans, proteins, lipids, uronic acids, hydrophobins, sporopollenin, and melanins, are discussed in detail. Special attention is given to chitin and its novel function in terms of protecting the cells from stress as well as to the differences of this fungal aminopolysaccharide from the chitin of algae and Arthropoda. The apical growth of hyphae and the involvement of special microvesicles in morphogenesis of a fungal cell are discussed. Data on the enzymes involved in CW synthesis and lysis are presented. In conclusion, the functional role of the fungal CW is discussed in juxtaposition to the surface structures of higher eukaryotes.
Mg acceptor level in AlN probed by deep ultraviolet photoluminescence (2003)

Mg-doped AlN epilayers were grown by metalorganic chemical vapor deposition on sapphire substrates. Deep UV picosecond time-resolved photoluminescence (PL) spectroscopy has been employed to study the optical transitions in Mg-doped AlN epilayers. From PL emission spectra and the temperature dependence of the PL emission intensity, a binding energy of 0.51 eV for Mg acceptor in AlN was determined. Together with previous experimental results, the Mg acceptor activation energy in AlxGa1−xN as a function of the Al content (x) was extrapolated for the entire AlN composition range. The average hole effective mass in AlN was also deduced to be about 2.7 m0 from the experimental value of the Mg binding energy together with the use of the effective mass theory.
Software Agents: Intelligent and Autonomous (1997)

When it comes to computing there is no doubt that it is a change ridden business. Procedural programming has given way, in many application areas at least, to object oriented programming. The next major paradigm to affect the way that we use computers, especially as we connect to the net with its attendant implications for us as users, is likely to be based on software agent technologies.
Short paper (2012)

Current smartphone platforms provide ways for users to control access to information about their location. For instance, on the iPhone, when an application requests access to location information, the operating system asks the user whether to grant location access to this application. In this paper, we study how users are using these controls. Do iPhone users allow applications to access their location? Do their decisions differ from application to application? Can we predict how a user will respond for a particular application, given their past responses for other applications?
Digital image reconstruction using Zernike moments (2004)

It is well known that, a piecewise function can be expanded by an orthogonal set of functions. If the expansion coeficients are suitable for a large number of terms, the reconstruction of function can be achieved with high accuracy. However, for a few of them the reconstruction of the input function, in general, is poor. In this work, we reconstruct discrete image functions using the complex Zernike polynomials. We compare the reconstruction of the input image function in two cases. When the input image is mapped inside or outside an unit circle for several expansion orders. To measure the reconstruction we use the relative error between the input and reconstructed images. Also, we show that the relative error can be reduced if the module of the complex discrete distribution of the reconstruction is squared.
Is glycosylation in the liver needed for insulin binding, processing, and action? Evidence for heterogeneity. (1984)

Incubation of primary cultures of rat hepatocytes with tunicamycin (1 microgram/ml) for 16 h inhibits de novo glycosylation by more than 90%, yet 50% of initial 125I-insulin binding is still present. The remaining insulin-binding activity is to glycosylated receptors, since they are adsorbed and specifically desorbed from wheat germ agglutinin-Sepharose. Furthermore, there is no difference in the molecular weight size of the alpha-subunit of the insulin receptors either in normal or tunicamycin-treated hepatocytes as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis of 125I-insulin receptor cross-linked with disuccinimidyl suberate. This gives us an opportunity to study the function of these glycosylated insulin receptors in cells where de novo glycosylation is inhibited. Inhibition of de novo glycosylation decreases receptor-mediated 125I-insulin internalization and degradation. The tunicamycin-treated cells are totally resistant to insulin with regard to [14C]aminoisobutyric acid uptake. In contrast, there is normal stimulation of [14C] acetate and [14C]glucose incorporation into lipids and glycogen by a maximal concentration of insulin. The interpretation of these data is, however, complicated by the fact that tunicamycin markedly inhibits basal lipid synthesis without altering basal glycogen synthesis or [14C]aminoisobutyric uptake. These results demonstrate the heterogeneity of the postinsulin binding system in the liver. Besides glycosylation of the insulin receptor, which is needed for insulin binding, other cellular glycoproteins are important for insulin processing as well as mediation of some, but not all, of the biological actions of insulin. The nature of these liver glycoproteins and their relationship to the insulin receptor have not yet been defined.
How Downhole Temperatures and Pressures Affect Drilling: ABSTRACT (1973)

This DOI is not currently attached to any metadata records. DOIs can’t actually ever be deleted (they’re persistent), but sometimes our members create DOIs in error. We do have a process to approximate deletion which we follow only in rare cases where the DOI has been genuinely created in error, and most crucially, if the DOI has never been published anywhere online or in print and never otherwise distributed to or communicated with anyone (authors, readers, reviewers, etc.
Photo-Responsive Shape-Memory and Shape-Changing Liquid-Crystal Polymer Networks (2013)

"Surrounding matters" is a phrase that has become more significant in recent times when discussing polymeric materials. Although regular polymers do respond to external stimuli like softening of material at higher temperatures, that response is gradual and linear in nature. Smart polymers (SPs) or stimuli-responsive polymers (SRPs) behave differently to those external stimuli, as their behavior is more rapid and nonlinear in nature and even a small magnitude of external stimulus can cause noticeable changes in their shape, size, color or conductivity. Of these SRPs, two types of SPs with the ability to actively change can be differentiated: shape-memory polymers and shape-changing polymers. The uniqueness of these materials lies not only in the fast macroscopic changes occurring in their structure but also in that some of these shape changes are reversible. This paper presents a brief review of current progress in the area of light activated shape-memory polymers and shape-changing polymers and their possible field of applications.

Sterol Carrier Protein-2 Overexpression Enhances Sterol Cycling and Inhibits Cholesterol Ester Synthesis and High Density Lipoprotein Cholesterol Secretion (1997)

Recent data indicate that sterol carrier protein-2 (SCP-2) functions in the rapid movement of newly synthesized cholesterol to the plasma membrane (Puglielli, L., Rigotti, A., Greco, A. V., Santos, M. J., and Nervi, F. (1995) J. Biol. Chem. 270, 18723-18726). In order to further characterize the cellular function of SCP-2, we transfected McA-RH7777 rat hepatoma cells with a pre-SCP-2 cDNA expression construct. In stable transfectants, pre-SCP-2 processing resulted in an 8-fold increase in peroxisomal levels of SCP-2. SCP-2 overexpression increased the rates of newly synthesized cholesterol transfer to the plasma membrane and plasma membrane cholesterol internalization by 4-fold. There was no effect of SCP-2 overexpression on the microsomal levels of acyl-CoA:cholesterol acyltransferase and neutral cholesterol ester (CE) hydrolase; however, in the intact cell, CE synthesis and mass were reduced by 50%. SCP-2 overexpression also reduced high density lipoprotein-cholesterol secretion and apoA-I gene expression by 70% and doubled the rate of plasma membrane desmosterol conversion to cholesterol. We conclude that SCP-2 overexpression enhances the rate of cholesterol cycling, which reduces the availability of cholesterol for CE synthesis and alters the activity of a cellular cholesterol pool involved in regulating apoA-I-mediated high density lipoprotein cholesterol secretion. The net result of these changes in cholesterol metabolism is a 46% increase in plasma membrane cholesterol content, the implications of which are discussed.
Dependence of depolarization temperature on cation vacancies and lattice distortion for lead-free 74(Bi1/2Na1/2)TiO3–20.8(Bi1/2K1/2)TiO3–5.2BaTiO3 ferroelectric ceramics (2009)

In this paper, the off-morphotropic-phase-boundary 74(Bi1/2Na1/2)TiO3–20.8(Bi1/2K1/2)TiO3–5.2BaTiO3 ceramics were fabricated at different sintering temperatures. It was found out that as the sintering temperature increases, the volatilization of the A-site elements is aggravated, thus generating the oxygen vacancies; meanwhile, the tetragonality of the perovskite lattice reduces gradually. Besides, the temperature-dependent dielectric responses revealed that as the sintering temperature increases, the depolarization temperature Td decreases while the Curie–Weiss point TC increases. It is suggested that the lattice distortion, other than the oxygen vacancies, is the crucial factor in influencing the depolarization temperature.
