Ontology-Based Automatic Receipt Accounting System (2012)

Most computer software available today -- although capable of processing text, numbers and other symbols -- cannot process meaning or nuances as we people do. One such case, which is the focus of this work, is the processing of number-rich documents, such as receipts to fulfill business-specific constraints. This task currently is labor intensive in the sense that we manually analyze the receipts and file the information in the required categories of business expenses reports. The premises of this paper is that it should be possible to overcome many of the limitations present in manual, number-rich information filing applications, by further understanding the lexical and semantic relationships through extraction ontologies. This paper introduces one such approach and describes preliminary experimental results that support this hypothesis.
ECG-gated versus nongated three-dimensional intracoronary ultrasound analysis: Implications for volumetric measurements (1998)

The quantitative analysis of a three-dimensional (3-D) intracoronary ultrasound (ICUS) image data set permits a more comprehensive assessment of coronary arterial segments. The 3-D image sets are generally acquired during continuous motorized pullbacks. However, the cyclic changes of vascular dimensions and the cyclic spatial displacement of the ICUS transducer relative to the vessel wall can result in characteristic image artifacts, which may limit the applicability of quantitative automated analysis systems. This limitation may be overcome by an ECG-gated image acquisition. In the present study we acquired in vivo (1) nongated and (2) ECG-gated 3-D ICUS image sets of 15 human atherosclerotic coronary arteries and performed a computer-assisted contour detection of the lumen and total vessel boundaries. Total vessel and lumen volumes measured significantly larger in the nongated versus ECG-gated end-diastolic image sets (753+/-307 mm3 vs. 705+/-305 mm3; 411+/-154 mm3 vs. 388+/-165 mm3, both: P < 0.05). Both end-diastolic and systolic measurements were available in nine arteries, showing a larger total vessel and lumen volume at systole (664+/-221 mm3 vs. 686+/-227 mm3, P=0.03; 384+/-164 mm3 vs. 393+/-170 mm3, P=0.08). The differences observed may be of particular interest for volumetric ICUS studies, addressing presumably small differences in vessel or lumen dimensions.
Effects of indomethacin, piroxicam and selected prostanoids on gastric acid secretion by the rat isolated gastric mucosa (1985)

The effects of the cyclo-oxygenase inhibitors indomethacin and piroxicam have been investigated on histamine- and dibutyryl cyclic AMP-induced acid secretion in the rat isolated gastric mucosa. The relative potencies of a number of prostanoids as inhibitors of histamine-induced acid secretion were determined in an attempt to classify the prostaglandin receptor mediating this response. Indomethacin (8 X 10(-9) - 2.7 X 10(-6) M) and piroxicam (3 X 10(-6) M) potentiated the secretory responses elicited by histamine. This effect might be due to inhibition of the biosynthesis of antisecretory prostanoids. Indomethacin (2.7 X 10(-6) M) and piroxicam (3 X 10(-6) M) also potentiated the secretory response to dibutyryl cyclic AMP, but since prostaglandin E2 (PGE2, 10(-5) M) did not inhibit this secretory response, the mechanism of the potentiation may differ from that of histamine. The potency of the thromboxane mimetic U-46619 as an inhibitor of histamine-induced acid secretion was markedly reduced in the presence of indomethacin, suggesting that U-46619 may release endogenous antisecretory prostanoids. In the presence of indomethacin (2.7 X 10(-6) M) all the prostanoids tested produced concentration-related inhibitions of histamine-induced gastric acid secretion. PGE-analogues were the most potent compounds, the rank order of potency being 16, 16 dimethyl PGE2 greater than PGE2 greater than PGF2 alpha greater than U-46619 greater than PGD2 greater than PGI2. This order of potency is very similar to that obtained in smooth muscle preparations containing 'EP' receptors, suggesting that this receptor type also mediates inhibition of histamine-induced acid secretion in the rat.
Effects of Direct and Indirect Bleach on Dentin Fracture Toughness (2007)

There are concerns that tooth-whitening procedures irreversibly damage tooth structure. We investigated the hypothesis that dental bleaches significantly affect dentin structural integrity. The objective was to evaluate the effects of peroxide bleaches on dentin fracture toughness. Compact test specimens, composed of human dentin, were used (n = 10/group). Bleach (16% or 10% carbamide peroxide or 3% hydrogen peroxide) or control material, containing 0.1% sodium fluoride, was applied directly or indirectly to dentin through enamel (6 hrs/day) for 2 or 8 weeks. Fracture toughness results were analyzed by ANOVA and Fisher's LSD test (p < 0.05). There were significant decreases in mean fracture toughness after two- and eight-week direct (19-34% and 61-68%, respectively) and indirect (up to 17% and 37%, respectively) bleach application. The in vitro reduction in dentin fracture toughness caused by the application of peroxide bleaches was greater for the direct application method, longer application time, and higher bleach concentration.

Human natural killer T cells acquire a memory-activated phenotype before birth (2000)

Natural killer T (NKT) cells have recently been shown to play an important role in the rejection of malignant tumors and in the regulation of autoimmune diseases. Potent antitumor effects of the marine sponge-derived NKT cell ligand KRN7000 were observed in mice. Therefore, the elucidation of the natural ligand of NKT cells, which is currently still unknown, might have important clinical consequences for the treatment of cancer and autoimmune diseases. Analysis of cord blood mononuclear cells from healthy term infants demonstrated that in sharp contrast with the vast majority of cord blood lymphocytes, human NKT cells have already acquired a memory-activated phenotype before birth. This observation indicates that NKT cells encounter a natural ligand during fetal life and that this ligand is unlikely to be of microbial origin.
Primary Structure of a Proline-Rich Zein and Its cDNA (1986)

Eighty-five cDNA clones for gamma-zein (proline-rich zein) from a cDNA expression library were isolated using specific antibody and cDNA probes. Nucleotide sequences of seven independent clones were determined and found to be identical in regions where they overlapped. The primary structure of the mature protein, determined from the sequence of one near full-length clone, consists of 204 amino acids. It has a molecular weight of 21,824 daltons, about 5 kilodaltons less than that estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The N-terminal one-half of the sequence contained eight essentially identical tandem repeats of the hexapeptide Pro-Pro-Pro-Val-His-Leu and two of the octapeptide Gln-Pro-His-Pro-Cys-Pro-Cys-Gln. The codon specifying the third proline in the hexapeptide repeating units is identical (CCG) in all of the eight repeats. The coding region has a very high G-C content (69.8%). The multiple charge components of gamma-zein detected by isoelectric focusing do not seem to be encoded by members of a multigene family. Moreover, it was found that the codon preference in gamma-zein is, in fact, the base preference in the wobble position. A codon usage value was devised to express this phenomenon.
Isolation of <i>anteiso</i>-C<sub>17</sub>, <i>iso</i>-C<sub>17</sub>, <i>iso</i>-C<sub>16</sub>, and <i>iso</i>-C<sub>15</sub> Bacillomycin D from Bacillus amyloliquefaciens SD-32 and Their Antifungal Activities against Plant Pathogens (2014)

Two new cyclic lipopeptides (3 and 4) were isolated from the culture filtrate of Bacillus amyloliquefaciens strain SD-32, together with two known metabolites, iso-C15 and iso-C16 bacillomycin D (1 and 2). Spectroscopic and chemical analyses identified the structures of the new compounds 3 and 4 as anteiso-C17 bacillomycin D, cyclic (l-Asn-d-Tyr-d-Asn-l-Pro-l-Glu-d-Ser-l-Thr-3-amino-14-methylhexadecanoic acid) and iso-C17 bacillomycin D, cyclic (l-Asn-d-Tyr-d-Asn-l-Pro-l-Glu-d-Ser-l-Thr-3-amino-15-methylhexadecanoic acid), respectively. The absolute configuration of C-3 in the β-amino fatty acid was determined to be R on the basis of the CD spectrum of its dinitrophenyl-p-methoxyaniline derivative. The activities of compounds 1-4 were evaluated against 13 plant pathogens: the activities of anteiso- and iso-C17 bacillomycin D (3 and 4) were almost the same and stronger than those of iso-C15 and iso-C16 bacillomycin D (1 and 2); iso-C15 bacillomycin D (1) was weakest. Compounds 2-4 inhibited the growth of all fungi tested; however, Pythium aphanidermatum was not inhibited at all by any of the compounds. Furthermore, compounds 1-4 at concentrations of 80, 40, 30, and 30 μM, respectively, inhibited completely the Botrytis cinerea infection in cucumber leaf.
Privacy Policy Preferences Enforced by SPARQL Query Rewriting (2012)

When specifying privacy preferences, the data owner can control who may access its personal data, for which purpose and under which accuracy. In this paper we present an approach that enforces the privacy policy preferences by query transformation. We present also how to instrument this rewriting query algorithm using a privacy-aware model like PrivOrBAC. We take into account various dimensions of privacy preferences through the concepts of consent, accuracy, purpose and recipient.
Coagulation of carbon particles in premixed flames (1973)

The size distribution, number concentration, and fraction charged of carbon particles at successive stage of formation in a low pressure flat flame were measured using molecular beam sampling, involving electrical beam deflection and electron microscopy of beam deposits and an optical absorption technique. Observed cluster-type structure within roughly spherical particles and decreasing particle number concentration following rapid nucleation, indicate the particles do indeed coagulate during growth. Particle size and number concentration data confirm this conclusion, although the experimental coagulation rate exceeds by a factor of about 10 the kinetic theory collision rate approximately adjusted for electrostatic forces, based upon the measured extent of particle charging, and Van der Waals attraction. Calculations, based upon extrapolation of the experimental coagulation rate constant into the flame region of significant particle nucleation and surface reaction, indicate that the particles nucleated first can grow predominantly by surface growth to a volume mean diameter of about 100 Å and that the number of primary particles per spherical unit within the final chainlike clusters is of order 10. Thus crystallites, the number of which is of order 103 per spherical unit, do not represent former particles.
Multicenter Randomized Comparison of the Efficacy and Safety of Xenon and Isoflurane in Patients Undergoing Elective Surgery (2003)

This first randomized controlled multicenter trial on the use of xenon as an inhalational anesthetic confirms, in a large group of patients, that xenon in oxygen provides effective and safe anesthesia, with the advantage of a more rapid recovery when compared with anesthesia using isoflurane-nitrous oxide.
Heavy Ion Nuclear Tracks—An Emerging Technology (1981)

Nuclear tracks are a logical extrapolation of the principles of cloud and bubble chamber onto solids. Besides their well‐known application in particle detection, in solids a completely new aspect arises, the generation of extremely fine permanent tracks, which can be transformed into open channels. Nuclear tracks are therefore a unique single‐particle structuring tool. Applications comprise (i) single hole membranes for particle counting and sizing, (ii) manufacture of microfilters with very uniform hole sizes, (iii) modification of magneto‐optic materials for application in display memories, and (iv) micromachining\ of surfaces.
Photo-oxidation of Methionine-containing Peptides by the 4-Carboxybenzophenone Triplet State in Aqueous Solution. Competition Between Intramolecular Two-centered Three-electron Bonded (S∴S)+ and (S∴N)+ Formation ¶ (2000)

Quantum yields for the formation of transients were measured following the quenching of triplet 4-carboxy-benzophenone (3CB*) by methionine-containing peptides in aqueous solutions. Ketyl radicals (CBH.), ketyl radical anions (CB.-) and various sulfur radical cations were identified following the triplet-quenching events. The presence of these intermediates indicated that the triplet-quenching mechanism can be characterized as mainly electron-transfer in nature. The quenching rate constants were of the order of 2 x 10(9) M-1 s-1. There were small, but significant, differences in the triplet-quenching rate constants, and these trends indicate the existence of multiple sulfur targets in the quenchers. The absorption of the transient products was followed in detail by using spectral-resolution analysis. From the absorption data, quantum yields were estimated for the formation of the various transients. There were differences found in the yields of the transient products between the experiments, where the quenchers were the "mixed" stereoisomers of methionylmethionine (L,D and D,L) and experiments where the quenchers were L,L and D,D stereoisomers. Triplet-quenching data from several other methionine-containing small oligopeptides were analyzed in an analogous manner. Systematic variations were observed, and these patterns were discussed in terms of competitive donation of protons to the CB.- within the charge-transfer complex. The competition was between protons on carbons adjacent to the sulfur-radical center and protons on the protonated amino groups of the radical cation. In addition, there was a competition between the two intramolecular two-centered, three-electron bonded species (S therefore S)+ and (S therefore N)+ that play roles in the secondary kinetics.
An approach towards feature specific opinion mining and sentimental analysis across e-commerce websites (2014)

This research aims to automate the process of gathering online, end user reviews for any given product or service and analyzing those reviews in terms of the sentiments expressed about specific features. This involves the filtering of irrelevant and unhelpful reviews, quantification of the sentiments of thousands of (useful) reviews. And finally, providing the end user (business/manufacturer) summarized data about the expressed sentiments in way of intuitive and easy to understand graphs, charts and other visualization. This data can then be used to improve business outcomes and ensure a very high level of customer satisfaction.

Structural Basis of Ion Pumping by Ca <sup>2+</sup> -ATPase of the Sarcoplasmic Reticulum (2004)

The structures of the Ca2+-ATPase (SERCA1a) have been determined for five different states by X-ray crystallography. Detailed comparison of the structures in the Ca2+ bound form and unbound (but thapsigargin bound) form reveals that very large rearrangements of the transmembrane helices take place accompanying Ca2+ dissociation and binding and that they are mechanically linked with equally large movements of the cytoplasmic domains. The meanings of the rearrangements of the transmembrane helices and those of the cytoplasmic domains as well as the mechanistic roles of phosphorylation are now becoming clear. Furthermore, the roles of critical amino acid residues identified by extensive mutagenesis studies are becoming evident in terms of atomic structure.

The RNA-Binding Protein DDX1 Promotes Primary MicroRNA Maturation and Inhibits Ovarian Tumor Progression (2014)

Posttranscriptional maturation is a critical step in microRNA (miRNA) biogenesis that determines mature miRNA levels. In addition to core components (Drosha and DGCR8 [DiGeorge syndrome critical region gene 8]) in the microprocessor, regulatory RNA-binding proteins may confer the specificity for recruiting and processing of individual primary miRNAs (pri-miRNAs). Here, we identify DDX1 as a regulatory protein that promotes the expression of a subset of miRNAs, including five members in the microRNA-200 (miR-200) family and four miRNAs in an eight-miRNA signature of a mesenchymal ovarian cancer subtype. A majority of DDX1-dependent miRNAs are induced after DNA damage. This induction is facilitated by the ataxia telangiectasia mutated (ATM)-mediated phosphorylation of DDX1. Inhibiting DDX1 promotes ovarian tumor growth and metastasis in a syngeneic mouse model. Analysis of The Cancer Genome Atlas (TCGA) reveals that low DDX1 levels are associated with poor clinical outcome in patients with serous ovarian cancer. These findings suggest that DDX1 is a key modulator in miRNA maturation and ovarian tumor suppression.
Dynamic framework for assessing cyber security risks in a changing environment (2016)

Cyber risk assessment frameworks aim at addressing a challenging problem that public and commercial organizations and nations embrace today - a proper estimation of likelihood of cyber-related risks and assessment of their potential impact on an enterprise. However, current frameworks fail at adapting to changes which happen in dynamically shifting environments and keep organizations blind to new possible threats. These threats may occur because of different changes happening internally or externally of the organization. For example, the global presence or digital footprint of the organization can significantly increase the exposure of an organization to cyber threats. Therefore, practitioners need new instruments which can be used to advise enterprises when and how their risk assessment methods and processes should be adjusted in order to stay relevant in a rapidly changing environment. In this work, the authors propose and validate a new method of applying a system dynamics approach for designing a dynamic risk assessment framework and introduce areas of future work.
New method for remote and repeatable monitoring of intraocular pressure variations (2014)

We present initial steps toward a new measurement device enabling high-precision, noncontact remote and repeatable monitoring of intraocular pressure (IOP)-based on an innovative measurement principle. Using only a camera and a laser source, the device measures IOP by tracking the secondary speckle pattern trajectories produced by the reflection of an illuminating laser beam from the iris or the sclera. The device was tested on rabbit eyes using two different methods to modify IOP: via an infusion bag and via mechanical pressure. In both cases, the eyes were stimulated with increasing and decreasing ramps of the IOP. As IOP variations changed the speckle distributions reflected back from the eye, data were recorded under various optical configurations to define and optimize the best experimental configuration for the IOP extraction. The association between the data provided by our proposed device and that resulting from controlled modification of the IOP was assessed, revealing high correlation (R2=0.98) and sensitivity and providing a high-precision measurement (5% estimated error) for the best experimental configuration. Future steps will be directed toward applying the proposed measurement principle in clinical trials for monitoring IOP with human subjects.
Dependence of coercivity on the anisotropy field in the Nd2Fe14B-type sintered magnets (1987)

The temperature dependence of the coercivity (HcI)of Nd15(Fe1−xCox)77B8 and (Nd1−xDyx)15Fe77B8 sintered magnets and that of the saturation magnetization (Ms) and the anisotropy field (HA) of Nd2(Fe1−xCox)14B and (Nd1−xDyx)2Fe14B single crystals have been observed in the temperature range between 295 and 800 K. The dependence of the coercivity on the major magnetic properties of the matrix phase in the Nd-Fe-B based magnets are investigated using the μ0HA vs μ0HcI+Ms plot. It is demonstrated that this method of analysis is useful in studying the coercivity mechanism of the Nd-Fe-B based sintered magnets.
INTERFACE PHENOMENA AND DIELECTRIC PROPERTIES OF BIOLOGICAL TISSUE (2002)

The dielectric properties of biological cells and tissues are very remarkable. They typically display extremely high dielectric constants at low frequencies, falling off in more or less distinct steps as the excitation frequency is increased. Their frequency dependence permits identification and investigation of a number of completely different underlying mechanisms, and hence, dielectric studies of biomaterials have long been important in electrophysiology and biophysics. As an example, Hober (1, 2) deduced from dielectric studies that erythrocytes are composed of a poorly conducting envelope enclosing a conducting electrolyte, and in 1925, Fricke (3) derived a value of 3.3 nm for the thickness of this envelope. Hence their bioimpedance research provided early indication of the ultrathin cell membrane. As we shall see later, interfaces play a significant role in the frequency dependence of complex materials, particularly at audio and subaudio frequencies.
Clinical Importance of Prognostic Factors (2008)

The term prognostic factor, when used regarding patients with malignancies, has taken on several meanings. In general, a prognostic factor is considered to be useful because its results serve to separate a large heterogeneous population into smaller populations with more precisely predictable outcomes. In theory, if this separation is both reliable and disparate, one can apply therapy more efficiently to the population by exposing those most likely to need and benefit from the therapy while ensuring that the other group avoids needless toxicities.
