Lineage tracing in data warehouses

Data warehousing systems collect data from multiple distributed data sources and store integrated and summarized information in local databases for efficient data analysis and mining. Sometimes, when analyzing data at a warehouse, it is useful to “drill down” and investigate the source data from which certain warehouse data was derived. For a given warehouse data item, identifying the exact set of source data items that produced the warehouse data item is termed the data lineage problem. This thesis presents our research results on tracing data lineage in a warehousing environment: (1) Formal definitions of data lineage for data warehouses defined as relational materialized views over relational sources, and for warehouses defined using graphs of general data transformations. (2) Algorithms for lineage tracing, again considering both relational and transformational warehouses, along with a suite of optimization techniques. (3) Performance evaluations through simulations, and a lineage tracing prototype developed within the WHIPS (WareHousing Information Processing System) project at Stanford. (4) Applying data lineage techniques to obtain improved algorithms for the well-known database view update problem.

A novel method for purifying a DNase from lysosomal fraction from human small intestine

Aims: The purification of an acid DNase related DNase II family from lysosomes of human small intestine (jejunum). Materials and Methods: Two different methods: a column chromatography series, including phosphocellulose, CM-cellulose and Sephadex G-200 and a novel procedure that use immunoabsorbent technique were used in the purification. Results: The purified DNase is an endonuclease that consisted of one polypeptide chain (monomer) with a molecular mass of 28-32kDa with an optimal pH and temperature of 6.0 and 30°C, respectively. The enzyme prefers native DNA on denatured DNA Discussion: The catalytic properties of the purified enzyme are essentially the same as those of DNase II family such as independency of divalent ions which inhibited its activity at 10mM. The enzyme acts on dsDNA and ssDNA and generates 3’-phosphate and 5’-OH termini which was a characteristic of DNase II. The functions of the intestinal purified DNase from lysosomes were unclear, but lysosomes contained a set of enzymes required for degradation of food, and the enzyme may be necessary for degradation of nucleic acids within food, but small amounts of the enzyme were found in the nuclei and cytoplasm were detected. Several researchers suggested that DNase II family may be active in apoptosis and played a role as a barrier to transfection. The purified was designated SIDNase.
MORPHOLOGICAL AND MOLECULAR DESCRIPTION OF HAEMATOLOECHUS MERIDIONALIS N. SP. (DIGENEA: PLAGIORCHIOIDEA: HAEMATOLOECHIDAE) FROM RANA VAILLANTI BROCCHI OF GUANACASTE, COSTA RICA

An undescribed species of Haematoloechus inhabits the lungs of Rana vaillanti in northwestern Costa Rica. The new species is most similar morphologically to H. medioplexus, having a very small, but well-developed, ventral sucker and lacking extracecal uterine loops, and apparently was mis-identified previously as H. medioplexus in Rana palmipes from Colombia. It differs from H. medioplexus, notably by (1) the shape of the oral sucker, which is elliptical in H. meridionalis and spherical in H. medioplexus; (2) the posterior extent of the vitelline fields, which terminate at the same level in H. medioplexus, but always at different levels in H. meridionalis; (3) the position of the testes, which are immediately posterior to the seminal receptacle and are close together in the new species and far from the seminal receptacle and separated from each other in H. medioplexus; and (4) the location of the genital pore, which is ventral to the cecal bifurcation in the new species and ventral to the pharynx in H. medioplexus. In addition, the new species is unique among members of Haematoloechus by having flaps of tissue on the interior margins of the ventral sucker. The new species shows almost 5% sequence divergence from H. medioplexus in the variable D1 region of the 28s rDNA, complementing the morphological differences.
Performance analysis of adaptive interleaving for OFDM systems

We proposed a novel interleaving technique for orthogonal frequency division multiplexing (OFDM), namely adaptive interleaving, which can break the bursty channel errors more effectively than traditional block interleaving. The technique rearranges the symbols according to instantaneous channel state information of the OFDM subcarriers so as to reduce or minimize the bit error rate (BER) of each OFDM frame. It is well suited to OFDM systems because the channel state information (CSI) values of the whole frame could be estimated at once when transmitted symbols are framed in the frequency dimension. Extensive simulations show that the proposed scheme can greatly improve the performance of the coded modulation systems utilizing block interleaving. Furthermore, we show that the adaptive interleaving out performs any other static interleaving schemes, even in the fast fading channel (with independent fading between symbols). We derived a semi-analytical bound for the BER of the adaptive interleaving scheme under correlated Rayleigh fading channels. Furthermore, we discussed the transmitter-receiver (interleaving pattern) synchronization problem.
The importance of ornithine as a precursor for proline in mammalian cells

Ornithine aminotransferase catalyzes the reversible transamination of L‐ornithine to δ1‐pyrroline‐5‐carboxylate, the immediate precursor of proline. The direction and flux through this pathway in mammalian cells has not been established. Glutamate has generally been considered to be the most important precursor for proline biosynthesis, but recent studies in xiphoid cartilage indicate that a significant fraction of cellular proline is derived from ornithine. Using newly isolated mutant Chinese hamster ovary cells with defined defects in the proline biosynthetic pathways, we now have established that cells can grow at a maximal rate with ornithine as the sole source of proline. Furthermore, we have measured the rate of proline formation from ornithine (1.6 nmol/h/106 cells). Future studies with these mutant Chinese hamster ovary cells may offer insight into the regulatory mechanism which coordinates proline biosynthesis from ornithine and glutamate.
Development of RAPD protocol for typing of strains of lactic acid bacteria and enterococci

P.S. COCCONCELLI, D. PORRO, S. GALANDINI AND L. SENINI. 1995. A protocol for typing strains of lactic acid bacteria and enterococci based on randomly amplified polymorphic DNA (RAPD) fragments has been developed. Using a single 10‐mer primer, fingerprints were achieved without the need to isolate genomic DNA. Different conditions of DNA release and amplification were investigated in order to obtain reproducible results and high discrimination among strains. This RAPD protocol was successfully applied for the typing of strains belonging to the species Lactobacillus acidophilus, Lact. helveticus, Lact. casei, Lact. reuteri, Lact. plantarum, Enterococcus faecalis, Ent. faecium and Streptococcus thermophilus.
Generalized p Values and Confidence Intervals for Variance Components: Applications to Army Test and Evaluation

Various mixed models that are relevant for analyzing Army test data are described, along with several hypothesis testing and interval estimation problems. The problems come up in the context of investigating gun tube accuracy of an M1 Series tank; in particular, for the study of tube-to-tube dispersion. Factors that affect tube-to-tube variability might include the tanks, ammunition lot, ammunition temperature, firing occasions, and so on. Some of these are fixed factors, and others are random factors. The inference problems that arise in the study of tube-to-tube dispersion are somewhat different from those usually encountered in typical ANOVA situations. A unified approach to solving these problems is presented using the concepts of generalized p values and generalized confidence intervals. The performance of the resulting tests and confidence intervals is numerically investigated and is found to be quite satisfactory. Analysis of some Army test data is presented to illustrate the results.
Face recognition system using bag of features and multi-class SVM for robot applications

Face recognition system is used for the identification and verification of a face from a video or digital image. In the first phase, Viola Jones algorithm is used to detect and crop face region automatically from image/video frame. The second phase is to recognize the face of a person, in our proposed method Bag of Word technique used to extract features from an image which uses SURF for interest point selection, the proposed technique is tested on different state of the art face recognition databases and found more accurate and fast for face recognition. Our proposed method recognizes more than two person faces, multi-class support vector machine is used to classify the face image and assign a class label based on the learning of the classifier. The algorithm for the detection and recognition of faces is implemented in MATLAB application, and achieves a high accuracy rate of 99.21, which will be tested on the mobile robot.
Are Glacials Dry? Consequences for Paleoclimatology and for Greenhouse Warming

AbstractPast cold climates are often thought to have been drier than today on land, which appears to conflict with certain recent studies projecting widespread terrestrial drying with near-future warming. However, other work has found that, over large portions of the continents, the conclusion of future drying versus wetting strongly depends on the physical property of interest. Here, it is shown that this also holds in simulations of the Last Glacial Maximum (LGM): the continents have generally wetter topsoils and higher values of common climate wetness metrics than in the preindustrial, as well as generally lower precipitation and ubiquitously lower photosynthesis (likely driven by the low CO2), with streamflow responses falling in between. Using a large existing global pollen and plant fossil compilation, it is also confirmed that LGM grasslands and open woodlands grew at many sites of present-day forest, seasonal forests at many sites of present-day rain forest, and so forth (116–144 sites out of 302).
Cloning and nucleotide sequencing of transthyretin (prealbumin) cDNA from rat choroid plexus and liver.

Transthyretin (TTR) cDNA clones were isolated from a xgtlO cDNA library prepared from choroid plexus RNA from inbred Buffalo rats, using a previously characterized Sprague-Dawley rat live TTR cDNA (1) as a probe. The complete nucleotide sequence was determined by dideoxy sequence analysis of both strands with overlapping fragments and is presented below.
Exploring linkage for alcoholism using affection status and quantitative event related potential phenotypes

Using genome‐scan data from the Collaborative Study on the Genetics of Alcoholism (COGA), we compared results of linkage analyses using a qualitative alcoholism phenotype to results of linkage analyses using event related potential (ERP) quantitative phenotypes, and compared our results to the results of Reich et al. [1998] and Begleiter et al. [1998]. We describe a general and simple strategy for identifying regions of the genome which may harbor genes involved in alcohol dependence which takes into consideration the results of both the affection status and ERP linkage analyses.
Objektsensitive Verfolgung und Klassifikation von Fußgängern mit verteilten Multi-Sensor-Trägern

Die Zustandsschatzung einer unbekannten Anzahl an Objekten stellt trotz der Existenz theoretisch Bayes-optimaler Multi-Objekt-Filter durch die grose Anzahl an Modellannahmen dieser Filter eine grose Herausforderung dar. In dieser Arbeit wurden die Eignung derartiger Filter fur den praktischen Einsatz in Multi-Objekt-Multi-Sensor-Szenarien untersucht und die Filter um notige Modellerweiterungen erganzt. Als Anwendungsszenario wurde auf die Verfolgung von Fusgangern in Innenraumen eingegangen.
Low Voltage Stochastic Flash ADC with Front-end of Inverter-based Comparative Unit

This paper presents a low supply voltage design of stochastic flash ADC, introducing an inverter-based comparative unit which is used as the front-end. A stochastic flash ADC has a significant advantage in reducing the supply voltage, while it needs a large number of comparators even for middle-level resolution. A key of our design is in the simplicity of the structure, and it enables us to decrease the number of transistors by replacing a comparator with a chain of inverters. Plus, the supply voltage can go down to 0.6V on 65nm process, as well as it can be designed with fully digital standard cells. We introduce a latch circuit combining with the chain of inverters for the signal stability, and discuss about an appropriate circuit structure for the resolution by analyzing three different structures. In the simulation, we demonstrate fundamental but promising results for a low voltage ADC design.
An SH2 Domain-dependent, Phosphotyrosine-independent Interaction between Vav1 and the Mer Receptor Tyrosine Kinase

Mer belongs to the Mer/Axl/Tyro3 receptor tyrosine kinase family, which regulates immune homeostasis in part by triggering monocyte ingestion of apoptotic cells. Mutations in Mer can also cause retinitis pigmentosa, again due to defective phagocytosis of apoptotic material. Although, some functional aspects of Mer have been deciphered, how receptor activation lead to the physiological consequences is not understood. By using yeast two-hybrid assays, we identified the carboxyl-terminal region of the guanine nucleotide-exchange factor (GEF) Vav1 as a Mer-binding partner. Unlike similar (related) receptors, Mer interacted with Vav1 constitutively and independently of phosphotyrosine, yet the site of binding localized to the Vav1 SH2 domain. Mer activation resulted in tyrosine phosphorylation of Vav1 and release from Mer, whereas Vav1 was neither phosphorylated nor released from kinase-dead Mer. Mutation of the Vav1 SH2 domain phosphotyrosine coordinating Arg-696 did not alter Mer/Vav1 constitutive binding or Vav1 tyrosine phosphorylation but did retard Vav1 release from autophosphorylated Mer. Ligand-dependent activation of Mer in human monocytes led to Vav1 release and stimulated GDP replacement by GTP on RhoA family members. This unusual constitutive, SH2 domain-dependent, but phosphotyrosine-independent, interaction and its regulated local release and subsequent activation of Rac1, Cdc42, and RhoA may explain how Mer coordinates precise cytoskeletal changes governing the ingestion of apoptotic material by macrophages and pigmented retinal epithelial cells.
Impact of an Elderspeak In-service Training on Resident Well-being, Self- esteem, and Communication Satisfaction

reinforce negative stereotypes of aging, deprive older adults of meaningful interactions, and erode their well-being. A brief communication in-service training based on Williams, Kemper, and Hummert (2003) was presented to nursing home staff to replace elderspeak with more helpful communication behaviors. Resident staff interactions were coded, and impact of the training on -esteem, and well-being was assessed across three time periods. A separate unit of untrained staff and residents served as a comparison group. Significant reductions in the proportion of interactions containing features of elderspeak were observed for the trained staff, along with significant increases in resident satisfaction, well-being, and self-esteem.
Influence of gender and socio‐economic status on dietary patterns and nutrient intakes in 18‐year‐old Australians

This study used two‐day diet records to examine dietary behaviours in 504 Australian 18 year‐olds in relation to gender, socio‐economic status (SES) and national dietary guidelines. Fat intake exceeded 30% of energy in about 80% of subjects and was greater than 40% in about one‐quarter. Saturated fat provided more than 10% of dietary energy in more than 90% of participants; less than 1% achieved a polyunsaturated to saturated fat ratio of at least one. The major food groups contributing to fat intake were convenience foods (32% in men, 28% in women) and meat (27% in men, 25% in women). Fibre intake was less than 30 g/day in 93% of women and 77% of men. Intakes of calcium, magnesium, potassium, and vitamins C and A, as a ratio of energy consumption, were greater in women than men, while sodium intake was significantly higher in men. Convenience foods were the greatest contributors to sodium intake (27% in men, 22% in women) followed by meat, bread, and soups and sauces. Greater consumption of cereals, fruit, vegetables and low‐fat foods in young women of higher SES was reflected in their nutrient profile with higher intake of fibre and vitamin C and lower intake of fat. Men ate more cereals, meat and sugary foods and less fruit, vegetables and low‐fat foods. Only 2.5% of men and 4.1% of women conformed with the health promotion message, widely publicised locally, to eat two fruits and five vegetables daily. Not eating breakfast was associated with lower calcium intake in men and women, and lower iron and fibre intake in women. Achieving behavioural changes in young adults must take into account differences in dietary behaviour related to gender and SES.
Acquisition and modeling of material appearance

In computer graphics, the realistic rendering of synthetic scenes requires a precise description of surface geometry, lighting, and material appearance. While 3D geometry scanning and modeling have advanced significantly in recent years, measurement and modeling of accurate material appearance have remained critical challenges. Analytical models are the main tools to describe material appearance in most current applications. They provide compact and smooth approximations to real materials but lack the expressiveness to represent complex materials. Data-driven approaches based on exhaustive measurements are fully general but the measurement process is difficult and the storage requirement is very high. In this thesis, we propose the use of hybrid representations that are more compact and easier to acquire than exhaustive measurement, while preserving much generality of a data-driven approach. To represent complex bidirectional reflectance distribution functions (BRDFs), we present a new method to estimate a general microfacet distribution from measured data. We show that this representation is able to reproduce complex materials that are impossible to model with purely analytical models. We also propose a new method that significantly reduces measurement cost and time of the bidirectional texture function (BTF) through a statistical characterization of texture appearance. Our reconstruction method combines naturally aligned images and alignment-insensitive statistics to produce visually plausible results. We demonstrate our acquisition system which is able to capture intricate materials like fabrics in less than ten minutes with commodity equipments. In addition, we present a method to facilitate effective user design in the space of material appearance. We introduce a metric in the space of reflectance which corresponds roughly to perceptual measures. The main idea of our approach is to evaluate reflectance differences in terms of their induced rendered images, instead of the reflectance function itself defined in the angular domains. With rendered images, we show that even a simple computational metric can provide good perceptual spacing and enable intuitive navigation of the reflectance space.

Non-Redundant Overlapping Clustering: Algorithms and Applications

Given a dataset, traditional clustering algorithms often only provide a single partitioning or a single view of the dataset. On complex tasks, many different clusterings of a dataset exist, thus alternative clusterings which are of high quality and different from given trivial clusterings are asked to have complementary views. The task is therefore a clear multi-objective optimization problem. However, most approaches in the literature optimize these objectives sequentially (one after another one) or indirectly (by some heuristic combination). This can result in solutions which are not Pareto- optimal. The problem is even more difficult for high-dimensional datasets as clusters can be located in various subspaces of the original feature space. Besides, many practical applications require that subspace clusters can still overlap but the overlap must be below a predefined threshold. Nonetheless, most of the state-of-the-art subspace clustering algorithms can only generate a set of disjoint or significantly overlapping subspace clusters. To deal with the above issues, for full-space alternative clustering, we develop an algorithm which fully acknowledges the multiple objectives, optimizes them directly and simultaneously, and produces solutions approximating the Pareto front. As for non-redundant subspace clustering, we propose a general framework for generating K overlapping subspace clusters where the maximum overlap between them is guaranteed to be below a predefined threshold. In both cases, our algorithms can be applied for several domains as different analyzing models can be used without modifying the main parts of the algorithms.
Current Status of Visual Field Examination in Andalusia, Spain: The SICVA Study

Purpose To ascertain the frequency of visual field examination (VFE) in patients attending public Andalusian hospitals (the SICVA study). Methods This was a multicenter, observational, retrospective study of patients with documented and/or suspected glaucoma subject to campimetric monitoring for longer than 2 years. The numbers of VFEs performed in the first 2 years and in the complete follow-up period were analyzed. Data on VFE reliability were studied and VFE change was collected based on the Glaucoma Staging System 2. Results A total of 722 eyes (from 467 consecutive patients), 349 with suspected and 373 with documented glaucoma, were included. Mean patient age was 65.9 years (SD = 11.3), and median follow-up time was 56 months (P25 = 36, P75 = 84). Three (P25 = 2, P75 = 4) VFEs were performed in the first 2 years of follow-up in the overall sample, as compared to 2 VFEs (P25 = 2, P75 = 4) in patients with suspected glaucoma, and 3 VFEs (P25 = 2, P75 = 4) in those with documented glaucoma (p<0.001). Conclusions Based on these results, frequency of VFE in Andalusia differs from the standards recommended by the European Glaucoma Society to assess progression in the first 2 years of patient follow-up.
