Integrity Mechanisms in Database Management Systems (2006)

. Our goal in this paper is to answer the following question: what mechanisms are required in a general-purpose multiuser database management system (DBMS) to facilitate the integrity objectives of information systems? We are particularly interested in relational DBMS&amp;apos;s. Although existing commercial products fall far short of providing the requisite mechanisms, in principle they can be easily extended to incorporate these mechanisms. In a nutshell our conclusion is that realistic mechanisms do exist. Our principal contribution is to identify these mechanisms, fill in the gaps where none existed and point out where gaps still remain. We have also bridged the terminology and concepts of database and security specialists in a coherent manner. 1 INTRODUCTION Information integrity means different things to different people, and will probably continue to do so for some time. The recent NIST workshop, which set out to establish a consensus definition, instead arrived at the following conclus...
Mechanical analysis and interpretation of excavation damage zone formation around deep tunnels within massive rock masses using hybrid finite–discrete element approach: case of Atomic Energy of Canada Limited (AECL) Underground Research Laboratory (URL) test tunnel (2018)

The construction of an underground opening leads to changes in the in situ stress regime surrounding the excavation. The opening influences the rock mass owing to the redistribution of the stresses and results in the disturbance of the surrounding ground. At great depths, massive to slightly or moderately fractured rock masses are usually encountered, and under high stresses, they are more likely to behave in a brittle manner during an excavation. While constitutive models have been developed and proposed for the numerical simulation of such excavations using continuum mechanics, this brittle response cannot be simulated accurately enough, since the material behaviour is governed by fracture initiation and propagation. On the contrary, discontinuum approaches are more suitable in such cases. For the purposes of this paper, the brittle behaviour of hard, massive rock masses and the associated spalling failure mechanisms were simulated by employing a finite–discrete element method (FDEM) approach using Irazu software. The generated numerical model was utilized to replicate field conditions based on the observations at the Atomic Energy of Canada Limited (AECL) Underground Research Laboratory (URL) test tunnel located in Pinawa, Manitoba, Canada. The model results are compared with field observation data to explicitly demonstrate the suitability of the method.
An Integrated Approach to the Detection, Localization, and Classification of Mines (2002)

Abstract : The best mine detectors, used both in US Army countermine operations and by humanitarian demining efforts that can afford them, are based on fifty-year-old technology comparable to metal detectors used by beachcombers. There is tremendous potential for improving the reliability of mine detection using state-of-theart sensors, computer modeling, and signal processing, combined with the phenomenal recent advances in computer power. The overall goal of humanitarian demining is to use these tools to help people around the world clear hazardous land at a cost that even developing countries can afford.
Amorphous mixed TiO2 and SiO2 films on Si(100) by chemical vapor deposition (2001)

Amorphous thin films of composition TixSi1-xO2 have been grown by low pressure chemical vapor deposition on silicon (100) substrates using Si(O-Et)4 and either Ti(O-iPr)4 or anhydrous Ti(NO3)4 as the sources of SiO2 and TiO2, respectively. The substrate temperature was varied between 300 and 535°C, and the precursor flow rates ranged from 5 to 100 sccm. Under these conditions growth rates ranging from 0.6 to 90.0 nm/min were observed. As-deposited films were amorphous to X-rays and SEM micrographs showed smooth, featureless film surfaces. Cross-sectional TEM showed no compositional inhomogeneity. RBS revealed that x (from the formula TixSi1-xO2) was dependent upon the choice of TiO2 precursor. For films grown using TTIP-TEOS x could be varied by systematic variation of the deposition conditions. For the case of TN-TEOS x remained close to 0.5 under all conditions studied. One explanation is the existence of a specific chemical reaction between TN and TEOS prior to film deposition. TEOS was mixed with a CCl4 solution of TN at room temperature to produce an amorphous white powder (Ti/Si = 1.09) and 1HNMR of the CCl4 solution indicated resonances attributable to ethyl nitrate.
Telomerase targeted oligonucleotide thio‐phosphoramidates in T24‐luc bladder cancer cells (2007)

Bladder carcinoma is the second most common genitourinary malignancy. Treatment options for bladder cancer include surgery, combined with chemotherapy, radiation, and/or immunotherapy. The adjuvant chemotherapy and immunotherapy regimen have been widely used in locally invasive as well as metastatic disease. The evaluation of new active agents with improved tolerability has been the focus of investigations over the past decade with minimal overall improvements in outcomes. Telomerase activity has been found in approximately 85-90% of all human tumors, but not in the majority of adjacent normal tissues. This suggests that telomerase may be an attractive target for the development of novel anticancer therapeutic agents. GRN163L is a lipid conjugated oligonucleotide N3' --> P5' thio-phosphoramidate, and is a potent telomerase RNA (hTR) template antagonist. In the present study, we show that the telomerase activity of T24-luc bladder cancer cells is inhibited by 1 microM GRN163L within 24 h of incubation. After two weeks of exposure to GRN163L, T24-luc cells became "clustered" whereas non-cancerous normal human uroepithelial cells were not morphologically affected. Moreover, in vitro GRN163L treated T24-luc bladder cancer cells entered G(0)/G(1) arrest following 2 weeks of continuous exposure and stopped dividing. Mismatch control compound had no effect on normal bladder epithelial cells or T24-luc cells. Additionally, a new generation of thio-phosphoramidate oligonucleotides were designed and tested in T24-luc cells and compared with GRN163L. The obtained results warrant further in vivo evaluation of GRN163L as a potential treatment for bladder cancer.
Thermal modeling and simulation of a package-on-package embedded micro wafer level package (EMWLP) structure at the package and system-level (2010)

In the embedded wafer-level packaging field, the embedded micro wafer level package (EMWLP) technology leverages on fan-out redistribution connections, keeping the reliance on wire-bonding and flip-chip bump connections to a minimum, thus streamlining the packaging process. As the embedded micro wafer level packaging (EMWLP) technology evolves to capitalize on package-on-package (POP) technology, this study's parametric thermal modeling focuses on analyzing the thermal impact of increased density in a low thermal conductivity packaging material. The package design in this work has the following specifications: the memory EMWLP (die size: 7×7×0.2mm) on logic EMWLP structure (die size : 8×8×0.2mm), sized 12×12×0.9mm in total. The POP structure, furthermore, incorporates through-mold-interconnects (TMI) in the bottom logic package to provide short electrical connection from the top package to the board level. The impact on multi-package thermal resistance is then studied as the following parameters vary: power dissipation (in both packages); mold conductivity; number of TMIs; number of solder ball connections; inclusion and size of an interpackage heatslug; inclusion and thermal conductivity of a top heatspreader. The thermal management of the dies are also studied based on the above measures and was found to accommodate under 4W of total POP power. Finally, simulation results for a general system-level thermal modeling of the EMWLP POP in a cellphone scenario are also conducted with passive thermal management solutions proposed.
X‐ray detectors based on Fe doped GaN photoconductors (2011)

Abstract X‐ray detectors based on Fe doped GaN photoconductors have been fabricated. The dark current I d and photocurrent I p as a function of bias have been investigated and a large I p / I d ratio of 180 at 200 V has been obtained in spite of optical quenching. The physical mechanism of the transient per‐ formance of the photoconductor has been studied through fitting the experimental data. The functions of photocurrent versus acceleration voltage and current of the X‐ray source have been measured and discussed. (© 2011 WILEY‐VCH Verlag GmbH &amp; Co. KGaA, Weinheim)
Ternary rare-earth metal oxide high-k layers on silicon oxide (2005)

Ternary oxides, GdScO3, DyScO3, and LaScO3, deposited by pulsed laser deposition using ceramics targets of stoichiometric composition, were studied as alternative high-k gate dielectrics on (100) Si. Their physical characterization was done using Rutherford backscattering, spectroscopic ellipsometry, x-ray diffraction, and transmission electron microscopy on blanket layers deposited on (100) Si, and electrical characterization on capacitors. It is found that DyScO3 and GdScO3 preserve their amorphous phases up to 1000°C. Other encouraging properties for high k applications were demonstrated, including k-value ∼22, almost no hysteresis or frequency dispersion in C–V curves, and leakage current reduction comparable to that of HfO2 of the same equivalent oxide thickness.
Techniques for extraction and isolation of natural products: a comprehensive review (2018)

Natural medicines were the only option for the prevention and treatment of human diseases for thousands of years. Natural products are important sources for drug development. The amounts of bioactive natural products in natural medicines are always fairly low. Today, it is very crucial to develop effective and selective methods for the extraction and isolation of those bioactive natural products. This paper intends to provide a comprehensive view of a variety of methods used in the extraction and isolation of natural products. This paper also presents the advantage, disadvantage and practical examples of conventional and modern techniques involved in natural products research.
Engineering Semantic Web Information Systems (2003)

Web Information Systems (WIS) use the Web paradigm and technologies to retrieve information from sources connected to the Web, and present the information in a web or hypermedia presentation to the user.Hera is a design methodology that supports the design of WIS.It is a model-driven method that distinguishes integration, data gathering, and presentation generation.In this paper we address the Hera methodology and specifically explain the integration model that covers the different aspects of integration, and the adaptation model, that specifies how the generated presentations are adaptable (e.g.device capabilities, user preferences).The Hera software framework provides a set of transformations that allow a WIS to go from integration to presentation generation.These transformations are based on RDF(S), and we show how RDF(S) has proven its value in combining all relevant aspects of WIS design.In this way, RDF(S) being the foundation of the Semantic Web, Hera allows the engineering of Semantic Web Information Systems (SWIS).
A Nonlinear Non-probabilistic Spot Interest Rate Model (1999)

We show how to use 'uncertainty' in place of the more traditional Brownian 'randomness' to model a short-term interest rate. The advantage of this model is principally that it is difficult to show statistically that it is wrong. Whether the model is useful for pricing fixed-income products is less clear. We discuss the pros and cons of the model, showing how to price and hedge various contracts, saying which are easy and which are hard.

Wound healing. The effects of topical antimicrobial agents (1979)

The effect of four commonly used topical antimicrobial agents on the rate of reepithelialization of clean wounds was evaluated in white domestic pigs. Neosporin Ointment was found to significantly increase the rate of reepithelialization by 25%, while Furacin significantly retarded the healing rate by 24%. Pharmadine, a preparation containing povidone-iodine, did not affect the rate of healing. Both Silvadene and its vehicle significantly increased the rate of reepithelialization by 28% and 21%, respectively. The effects of these agents cannot be explained on the basis of their antimicrobial activity.
Coordinated Beam Selection for Training Overhead Reduction in FDD Massive MIMO (2019)

While acquiring channel state information at the transmitter (CSIT) in time division duplexing systems can exploit channel reciprocity, acquiring accurate CSIT in frequency division duplexing massive multiple-input multiple-output systems is not trivial. The two main difficulties in these systems are the scalability of the downlink reference signals and the overhead associated with the required uplink feedback. Although several approaches for ensuring scalability and reducing overhead by leveraging some presumed channel properties have been studied, existing schemes do not offer a fully satisfactory solution. In this work, we propose a novel cooperative method which exploits low-rate beam-related information exchange between the mobile terminals, reduces the overhead under the assumption of the so-called grid-of-beams design, and strikes a balance between CSIT acquisition overhead, user spatial separability and coordination complexity.
The NSW Music (K-6) Syllabus and Support Statements (1984): Implications for Tertiary Institutions (1987)

The NSW Music (K-6) Syllabus and Support Statements released in 1985 committed to the teaching of music in NSW government primary schools. This statement is used as a reference to reassess the contribution made by NSW tertiary institutions to primary music education in the State.
A multi-resolution filling-in model for brightness perception (1999)

We present a multiscale neural filling-in model for brightness reconstruction of initial DoG filtered images. In contrast to the classical single-scale filling-in models it no longer requires an additional (luminance) signal to restore arbitrary images. Moreover, it substantially reduces the computational cost of the reconstruction process. We present a multilayered hierarchical neural network comparable to a Laplacian pyramid in which contrast measures are filled-in in dedicated frequency domains. We show in simulations how this model operates on synthetic as well as on real-world images.
A latching accelerometer fabricated by the anisotropic etching of (110) oriented silicon wafers (1992)

The anisotropic etching of (110) oriented silicon wafers is used to fabricate a simple latching accelerometer for moderate and high-g applications. This accelerometer consists of two cantilever beams that interlock at a set threshold acceleration which is determined by their design. The accelerometer is robust, fairly easy to fabricate and can be mass produced. Two units designed to latch at 85 g and 600 g were tested on a centrifuge and the error between the calculated latching acceleration and the experimental result was less than 15%. Arrays of accelerometers can be easily fabricated on the same silicon wafer to bracket the true acceleration. Readout schemes could include either capacitive or optical techniques. The structure can be easily designed for a wide range of acceleration ranging from a few g to several thousand g.
Chondrocyte‐specific Smad4 gene conditional knockout results in hearing loss and inner ear malformation in mice (2009)

Smad4 is the central intracellular mediator of transforming growth factor-beta (TGF-beta) signaling, which plays crucial roles in tissue regeneration, cell differentiation, embryonic development, and regulation of the immune system. Conventional Smad4 gene knockout results in embryonic lethality, precluding its use in studies of the role of Smad4 in inner ear development. We used chondrocyte-specific Smad4 knockout mice (Smad4Co/Co) to investigate the function of Smad4 in inner ear development. Smad4Co/Co mice were characterized by a smaller cochlear volume, bone malformation, and abnormalities of the osseous spiral lamina and basilar membrane. The development of the hair cells was also abnormal, as evidenced by the disorganized stereocilia and reduced density of the neuronal processes beneath the hair cells. Auditory function tests revealed the homozygous Smad4Co/Co mice suffered from severe sensorineural hearing loss. Our results suggest that Smad4 is required for inner ear development and normal auditory function in mammals.
Primary Recrystallization and Grain Growth of Tough Pitch Copper Wire (1995)

Tough pitch copper wire (99.97% Cu) is generally characterized by the spiral elongation number. The principle of the test is based on the influence of impurities on the recrystallization kinetics. Alternative non-metallographic techniques to characterize the recrystallization kinetics have been investigated in this study, such as differential scanning calorimetry (D.S.C.) and residual electrical resistivity measurement. The influence of different impurity levels on recrystallization is discussed. Furthermore, discontinuous grain growth in hot rolled rod is reported. As the heat released in this process is much smaller than in the case of primary recrystallization, D.S.C. is less appropriate to detect it and therefore a technique based on the attenuation of ultrasonic waves is proposed.
Deletion of the fibrogen alpha-chain gene (FGA) causes congenital afibrogenemia (1999)

Congenital afibrinogenemia is a rare autosomal recessive disorder characterized by the complete absence of detectable fibrinogen. Uncontrolled bleeding after birth from the umbilical cord is common, and spontaneous intracerebral bleeding and splenic rupture can occur throughout life. Patients respond well to fibrinogen replacement therapy, either prophylactically or on demand. Because the half-life of infused fibrinogen is essentially normal, the genetic defect is assumed to be at the level of synthesis, but no responsible locus has been identified. Preliminary studies using Southern blotting suggested that no gross structural changes of the fibrinogen genes were present in patients. We report the identification of causative mutations in a nonconsanguineous Swiss family with congenital afibrinogenemia. The four affected male individuals (two brothers and their two first cousins) have homozygous deletions of approximately 11 kb of the fibrinogen alpha-chain gene (FGA). Haplotype data suggest that these deletions occurred separately, on three distinct ancestral chromosomes, implying that the FGA region of the fibrinogen locus is susceptible to deletion by a common mechanism. Furthermore, our results demonstrate that humans, like mice, may be born without the capacity to synthesize functional fibrinogen.

Quasi-Bloch Oscillations in Curved Coupled Optical Waveguides (2009)

We report the observation of quasi-Bloch oscillations, a recently proposed, new type of dynamic localization in the spatial evolution of light in a curved coupled optical waveguide array. By spatially resolving the optical intensity at various propagation distances, we show the delocalization and final relocalization of the beam in the waveguide array. Through comparisons with other structures, we show that this dynamic localization is robust beyond the nearest-neighbor tight-binding approximation and exhibits a wavelength dependence different from conventional dynamic localization.
Identification by immunobinding assay of the polypeptide coded by the DNA polymerase gene of bacteriophage T5 and its amber mutants and the direction of transcription of the gene (1985)

We identified by immunobinding assay the polypeptides synthesized as the result of amber mutations in the DNA polymerase gene of bacteriophage T5. Comparison of the size of such polypeptides revealed the order of mutagenic loci of these mutations and the direction of transcription of the gene. Extracts of cells infected with wild-type T5 and with five amber mutants of the polymerase gene (D7, D8, D9, am1, and am6) were prepared, and the proteins were resolved by sodium dodecyl sulfate-polyacrylamide slab gel electrophoresis. After transfer of the proteins to a nitrocellulose sheet, a radioimmunolabeling technique was used to identify the T5 DNA polymerase and its amber mutant polypeptides. Based on the relative sizes of the polypeptides, the transcription of the T5 DNA polymerase gene was determined to proceed in the order D7, D8, am1, D9, and am6. The molecular weights of the DNA polymerase polypeptides coded by D8, am1, D9, am6, and T5+ were 23,000, 45,000, 75,000, 83,000, and 96,000, respectively. The D7-coded polypeptide was not detectable. These data suggest that the carboxyl-terminal region of the enzyme is essential for the polymerase function.
The Anti-Apoptotic Activity of BAG3 Is Restricted by Caspases and the Proteasome (2009)

BAG3 is tightly controlled by selective degradation during STS exposure. Loss of BAG3 under STS injury required sequential caspase cleavage followed by polyubiquitination and proteasomal degradation. The need for dual regulation of BAG3 in apoptosis suggests a key role for BAG3 in cancer cell resistance to apoptosis.
