Discovering Regions of Correlated Change in Dynamic Graphs (2009)

Many types of applications involve large datasets that describe the relationships between a set of entities. This has led to a growing need to design data mining algorithms to find interesting and significant patterns in these very large datasets. In these types of data mining problems, graphs provide a natural representation for such relational data. Hence, there has been a growth in research into graph mining – the field of finding interesting patterns in graphs. Most existing graph mining work considers graphs as non-changing and static, but many graph datasets do changewith time. There has been recent work on algorithms that take the dynamics of graphs into consideration, such as finding subgraphs that are frequent across multiple periods of time in a dynamic graph. However, none of the current work discovers groups of vertices and edges of a dynamic graph that change in a similar manner and are topologically close. These groups of vertices and edges are called regions of correlated spatio-temporal change. They can be used in a variety of contexts, including fault localisation in multi-layered computer networks, identification of activated parts of the brain during different activities and discovering trends in spatio-temporal datasets. In this thesis, we introduce the new concept of regions of correlated spatio-temporal change and the associated problem of finding these regions in dynamic graphs. Given that graph datasets can be very large, algorithms to find these regions must be scalable and the regions discovered by the algorithms must be accurate. In this thesis, we introduce three different algorithms to discover the regions in a dynamic graph and we propose a new method to evaluate the accuracy of discovered regions. The first algorithm we propose to find regions of correlated change is a greedy approach. It considers the region discovery problem as a multi-objective clustering prob-

Detecting backoff misbehaviour in IEEE 802.11 EDCA (2010)

Abstract In this paper, we suggest the use of the chi‐square test for detecting backoff misbehaviour in IEEE 802.11 EDCA networks. A performance evaluation is performed to compare the chi‐square test with two other methods, known in the literature. To perform a suitable comparison, these two methods are extended to support EDCA and the BEB mechanism. We assume a misbehaviour model, which can be easily executed by a selfish user. We show that the chi‐square test outperforms the other methods in terms of the probability of misbehaviour detection and time required to positively identify a misbehaving node.

Standardization of conditions for the metabolic activation of N-nitrosodiethylamine in mutagenicity tests. (2004)

Like all nitrosamines, N-nitrosodiethylamine (NDEA) requires metabolic activation in order to exert its carcinogenic effects. This activation involves cytochrome P450s (CYP), which generates unstable metabolites that react with the DNA of cells in the immediate vicinity of metabolite formation. Although NDEA is carcinogenic, it has been considered a weak mutagen in classic genotoxicity assays. We used optimized Salmonella/mammalian microsome genotoxicity assays to assess the mutagenicity and toxicity of low concentrations of NDEA. Using a fixed concentration of NDEA (36.5 mg/ml), we varied the length of preincubation in the presence of different concentrations of an S9 metabolic activation mixture. Salmonella typhimurium strains TA97 and TA102 were resistant to NDEA-induced mutagenesis, even after a preincubation of up to 120 min and the use of different concentrations of the S9 mix. Strain TA98 was susceptible to mutagenesis by NDEA in the absence of the S9 mix and after preincubation with NDEA for 90 min. When bacteria of this strain were preincubated with NDEA for 60 min, mutagenesis was detected at an S9 mix concentration >9.55 mg/ml. NDEA also induced mutagenesis in strain TA100 after preincubation for 90 or 120 min, and this effect was dependent on the S9 concentration. E. coli strain BH990 also showed a concentration-dependent response, with only 60% of the cells surviving after a 120-min preincubation with NDEA in the presence of 19.1 mg S9 mix/ml.
The Rat as an Experimental Animal (1989)

The development and characterization of many inbred, congenic, and recombinant strains of rats in recent years has led to the detailed genetic description of this species, especially in regard to its major histocompatibility complex. This information has contributed substantially to the study of comparative genetics and has greatly enhanced the utility of the rat in a variety of areas of biomedical research. This article focuses on the use of the rat in immunogenetics, transplantation, cancer-risk assessment, cardiovascular diseases, and behavior.
A Survey on Intrusion Detection Approaches (2006)

Intrusion detection plays one of the key roles in computer security techniques and is one of the prime areas of research. Usages of computer network services are tremendously increasing day by day and at the same time intruders are also playing a major role to deny network services, compromising the crucial services for Email, FTP and Web. Realizing the importance of the problem due to intrusions, many researchers have taken up research in this area and have proposed several solutions. It has come to a stage to take a stock of the research results and project a comprehensive view so that further research in this area will be motivated objectively to fulfill the gaps exists till now.

Noise and sensitivity analysis of periodically switched linear circuits in frequency domain (2000)

This paper presents new theories and efficient computational methods for noise and sensitivity analysis of multiphase periodically switched linear (PSL) circuits in frequency domain. Tellegen's theorem for PSL circuits in the phasor domain, frequency reversal theorem, and transfer function theorem, are introduced. The adjoint network of PSL circuits is developed using a frequency-domain approach. An adjoint network-based noise analysis algorithm for PSL circuits is proposed. It is shown that the computational overhead associated with multiple noise sources is eliminated by using the transfer function theorem. It is also shown that the excessive cost of computation due to aliasing effects is significantly reduced when the frequency reversal theorem is employed. In sensitivity analysis, the incremental form of Tellegen's theorem for PSL circuits in the phasor domain is introduced and frequency-domain sensitivity of PSL circuits Is obtained. It is shown that frequency-domain sensitivity of PSL circuits is a series summation of the network variables. Both the baseband and sideband frequency components of the network variables contribute to baseband sensitivity. The method yields sensitivities of one output with respect to all circuit elements in one frequency analysis. Sensitivity networks of PSL circuits are introduced. It is demonstrated that both the adjoint and sensitivity network approaches give the same sensitivity. Numerical results computed using the proposed methods are compared with measurement data and those from other CAD tools.
Analysis and detection of arcing faults in low-voltage electrical power systems (2002)

This work focuses on developing a more complete understanding of the properties of arcing fault waveforms in a 230 volt, three-phase electrical system and to detect them in a cost efficient way. Analysis of waveform properties of experimental arcing fault current waveforms revealed significant variations from an unfaulted system current. Using the results of the analysis of the data gathered from the experimental setup, an analog detector was developed and tested under faults with various loading conditions. >
Nanocrystalline Metal Chalcogenides Obtained Open to Air: Synthesis, Morphology, Mechanism, and Optical Properties (2009)

Nanocrystalline metal chalcogenide (selenide/sulfide/telluride) semiconductors make great sense in the photoelectric applications. Since the size and shape of the nanomaterials have a strong influence on their properties, new methods with high feasibility are always expected for the synthesis of chalcogenides with different dimension and morphology. In the present work, a green acetate−paraffin route was introduced that is suitable for the preparation of different chalcogenides, such as PbSe, Cu2Se, ZnSe, CdSe, NiSe2, CoSe, ZnS, Cu7.2S4, and PbTe. All the experiment processes were conducted open to air. These chalcogenides show various morphologies like grains, nanospheres, nanoplates, and so on. A mechanism was proposed to explain the formation of the different chalcogenide nanostructures. The dimension and shape of the nanostructures are dependent both on the crystal structure and the action of oleic acid on the growth rate of crystal faces. The optical properties of the prepared chalcogenides were characterized by the UV−visible diffuse reflectance spectroscopy (UV-DRS) and photoluminescence (PL) spectroscopy.
Low-cross-talk polarization-insensitive 10-GHz-spaced 128-channel arrayed-waveguide grating multiplexer–demultiplexer achieved with photosensitive phase adjustment (2001)

We successfully fabricated a polarization-insensitive 10-GHz-spaced 128-channel arrayed-waveguide grating whose cross talk ranged from -39 to -36 dB . The optical phases of all arrayed waveguides were adjusted simultaneously by means of a photoinduced refractive-index change under ArF excimer laser irradiation through metal masks.
Ischaemic Preconditioning Inhibits Opening of Mitochondrial Permeability Transition Pores in the Reperfused Rat Heart (2003)

Opening of the mitochondrial permeability transition pore (MPTP) is thought to be a critical event in mediating the damage to hearts that accompanies their reperfusion following prolonged ischaemia. Protection from reperfusion injury occurs if the prolonged ischaemic period is preceded by short ischaemic periods followed by recovery. Here we investigate whether such ischaemic preconditioning (IPC) is accompanied by inhibition of MPTP opening. MPTP opening in Langendorff‐perfused rat hearts was determined by perfusion with 2‐deoxy[ 3 H]glucose ([ 3 H]DOG) and measurement of mitochondrial [ 3 H]DOG entrapment. We demonstrate that IPC inhibits initial MPTP opening in hearts reperfused after 30 min global ischaemia, and subsequently enhances pore closure as hearts recover. However, MPTP opening in mitochondria isolated from IPC hearts occurred more readily than control mitochondria, implying that MPTP inhibition by IPC in situ was secondary to other factors such as decreased calcium overload and oxidative stress. Hearts perfused with cyclosporin A or sanglifehrin A, powerful inhibitors of the MPTP, also recovered better from ischaemia than controls (improved haemodynamic function and less lactate dehydrogenase release). However, the mitochondrial DOG entrapment technique showed these agents to be less effective than IPC at preventing MPTP opening. Our data suggest that protection from reperfusion injury is better achieved by reducing factors that induce MPTP opening than by inhibiting the MPTP directly.
SIGNATURES FROM SINGLE AIRGUNS* (1983)

A bstract The far‐field signatures from a comprehensive and systematic airgun pulse test have been analyzed. Empirical relations between the characteristic signature parameters and depth (5–12 m), pressure (100–137 bar = 10–13.7 MPa) and total chamber volume (0.65–9.5 l) have been derived. Also, the influence of using waveshape kits in different positions within the chamber has been tested. The results indicate that: The amplitude is proportional to chamber pressure to the power 3/4. The bubble period is nearly independent of the position of the waveshape plate. The increase in primary/bubble amplitude ratio is inversely proportional to the chamber volume above the waveshape plate. The amplitude is independent of airgun depth. Suggestions and comments regarding this work from Dr B. Ursin and Dr A. Ziolkowski are appreciated. The field work was supported by the Norwegian Petroleum Directorate through the Continental Shelf Project at the Seismological Observatory, University of Bergen. An airgun allowing for continuous variation of the chamber volumes was supplied by GECO (Geophysical Company of Norway). The purchase of two airguns was financed by Norske Getty Exploration A/S.

Regenerative Frequency Division with a GaAs FET (1984)

The circuit concept to be described accomplishes regenerative frequency division by employing a GaAs FET which is biased near pinchoff. The concept aims at efficient utilization of basic device characteristics, providing well-behaved divider performance and easy circuit designability. This is exemplified with the help of an experimental 16-to-8-GHz divider circuit whose output response is studied for single-tone CW, RF-pulsed, and two-tone CW excitations.
Être patrimoine, la vie de quatre monuments historiques : quatre siedlungen berlinoises des années 1920, Britz, Onkel Toms hütte, Siemensstadt, Weibe Stadt (2011)

Entre 1918 et 1933, la ville de Berlin s’est développée comme métropole de l’art moderne. La concrétisation architecturale et sociale du mouvement Moderne s’exalte dans la construction de logements : la Siedlung est la manifestation matérielle du mouvement novateur socialiste de l’entre-deux guerres. Soutenue par l’État, la construction de logements à bon marché se développa entre 1919 et 1930. Britz, Onkel Toms Hütte, Siemensstadt et Weibe Stadt, quatre Siedlungen réparties et construites dans la périphérie berlinoise en font partie. Emblèmes de la ville de Berlin, elles sont aujourd’hui des monuments historiques malgré l’histoire mouvementée de leur patrimonialisation. Ce mémoire s’intéresse à cette histoire qui va de leur construction jusqu’à leur patrimonialisation.
Hot-spot p53 mutants interact specifically with two cellular proteins during progression of the cell cycle. (1994)

Inactivation of both alleles of the p53 gene is commonly found in human cancers. In contrast to mutations of the retinoblastoma gene, certain altered forms of p53 gain growth-promoting functions. To explore the mechanisms underlying this gain of function, we have identified two nuclear proteins, with molecular masses of 42 and 38 kDa, respectively, that are specifically associated with p53 mutated within the simian virus 40 T-antigen-binding domain, "hot spots" found in many human tumors. These mutants transactivate the multiple-drug resistance gene promoter and cause cells to grow to higher density. Both the mutated p53 complex with p42 and p38 increase when cells enter S phase of the cell cycle but decrease in G1 and M phases, suggesting that they may have a role in promoting cell growth.
Monomeric plasticizers for PVC medical devices: Safety and regulatory status (1984)

Abstract As the data base for phthalates and other monomeric plasticizer classes is broadened, and our understanding of toxic mechanisms and potential risks improves, it is anticipated that industry and government agencies alike will demonstrate that these products can be safely used. Progress will depend heavily on advancements in predictive animal testing science, and extrapolation of animal data to meaningful risk assessment in humans. Future directions for testing initiatives are being determined, with a leadership role being played by CMA. Much exploratory work remains, but the focus will continue to narrow on areas critical to human risk assessment.
Computation of Elastic Properties of Portland Cement Using Molecular Dynamics (2011)

There is a growing interest in relating nanostructures to the macro properties of engineering materials such as composites and cement materials. Better understanding of structure and elastic properties of nanoparticles in concrete by modeling and experiment could lead to nanoengineered concrete with much better performance and energy efficiency. In this study, the molecular dynamics (MD) atomistic simulation technique was applied to study the elastic properties of major portland cement compounds (i.e., alite, belite, and aluminate). Applicability of three commonly used force fields: COMPASS, Universal force field (UFF), and Dreiding were evaluated in the MD simulation. The combination of different simulation cell sizes and force fields was investigated. MD simulation results of cement were comparable to the experimental data. The results could be used as nanoparticle properties for multiscale modeling of concrete, cementitious composites, and aggregate.

A hybrid case-based medical diagnosis system (2002)

This paper proposes a hybrid case-based system to help the physician. It includes a hypermedia human-machine interface and a hybrid case-based reasoner. The hypermedia human-machine interface provides a friendly human body image map for the clinician to easily enter a given consultation. It utilizes a medicine-related commonsense knowledge base to help complete the input data during the consultation. The hybrid case-based reasoner is responsible for selecting and adapting relevant cases from the case library into a diagnosis for the consultation. This reasoner does those jobs by hybridizing many techniques. Basically it uses a distributed fuzzy neural network for case retrieval. It employs decision theory, constrained induction trees, and relevance theory for case adaptation involving case combination. The technique is also used for learning new cases into the case library. Hybridizing these techniques together can effectively produce a high quality diagnosis for a given medical consultation.
