ANSI SQL hierarchical processing can fully integrate native XML (2003)

Most SQL-based XML vendor support is through interoperation and not integration. One reason for this is that XML is inherently hierarchical and SQL is supposedly not. This paper demonstrates how ANSI SQL along with its relational Cartesian product model can naturally perform complete and flexible hierarchical query processing. With this ANSI SQL inherent hierarchical processing capability, native XML data can be fully and seamlessly integrated into SQL processing and operated on at a full hierarchical level. This paper will describe the basic stages involved in this hierarchical SQL processing: hierarchical data modeling, hierarchical working set creation, and hierarchical Cartesian product processing. These processes enable a complete relational, XML, and legacy data integration which maintains ANSI SQL compatibility even while performing the most complex multi-leg hierarchical processing, and includes the dynamic, direct, and controlled hierarchical joining of hierarchical structures. Also covered are ANSI SQL hierarchical support features: hierarchical SQL views, hierarchical data filtering, and hierarchical optimization. These make standard SQL a well rounded and complete hierarchical processor. With this full hierarchical level of processing established, it will be shown how the relational Cartesian product engine can be seamlessly replaced with a hierarchical engine, greatly increasing processing and memory utilization, and enabling advanced XML hierarchical data capabilities.

Algunos aspectos de la historia social del sida en los inicios de la epidemia (2012)

Se hizo una revisión bibliográfica sobre la historia social de la epidemia del sida, y se analizó y resumió los aspectos más relevantes de diversas publicaciones. El sida fue un problema de salud que tenía un fuerte impacto social por la desinformación, la discriminación, la economía familiar y del país, y la reacción de familiares y amigos ante el diagnóstico positivo, lo cual hizo que esta enfermedad se convirtiera tanto en un problema social como de salud pública. A pesar de ello, los científicos sociales no eran tomados en cuenta para hacer frente a la epidemia, porque la prioridad era conseguir una vacuna que pudiera curar a los infectados con el virus VIH.
Safety, efficacy, and clinical utility of asparaginase in the treatment of adult patients with acute lymphoblastic leukemia (2017)

Abstract: Adults with acute lymphoblastic leukemia (ALL) are known to have inferior outcomes compared to the pediatric population. Although the reasons for this are likely manyfold, the agents utilized and the increased intensity of pediatric treatments compared to adult treatments are likely significant contributing factors. Asparaginase, an enzyme that converts asparagine to aspartic acid, forms the backbone of almost all pediatric regimens and works by depleting extracellular asparagine, which ALL cells are unable to synthesize. Asparaginase toxicities, which include hypersensitivity reactions, pancreatitis, liver dysfunction, and thrombosis, have hindered its widespread use in the adult population. Here, we review the toxicity and efficacy of asparaginase in adult patients with ALL. With the proper precautions, it is a safe and effective agent in the treatment of younger adults with ALL with response rates in the frontline setting ranging from 78% to 96%, compared to most trials showing a 4-year overall survival of 50% or better. The age cutoff for consideration of treatment with pediatric-inspired regimens is not clear, but recent studies show promise particularly in the adolescent and young adult population. New formulations of asparaginase are actively in development, including erythrocyte-encapsulated asparaginase, which is designed to minimize the toxicity and improve the delivery of the drug.

Cornstalk as a source of fiber and energy (2006)

Wood is the major source of fiber supply. Non-wood fibers are mainly used in papermaking where there is a lack of forest resource such as in China and India. Cornstalk, among the agricultural residues and other non-wood fiber, is the most promising source of fiber. However, The usage of cornstalks is very limited in pulp and paper industry, although nearly 284 million tons/year are available worldwide, including 150 million tons/year in the United States. Cornstalk contains about 27 % hemicelluloses, which is higher than most of the hardwoods and non-wood fiber materials. Preservation of hemicelluloses in papermaking fiber is important for increased fiber-to-fiber bonding and pulp yield. Unfortunately, in conventional pulping process, most of the hemicelluloses are degraded and ends up in pulping liquor. The calorific value of hemicelluloses derivatives in black liquor is very low compare to lignin derivatives. A value added alternative is to partially extract hemicellulose in cornstalk prior to pulping by dilute acid hydrolysis in the form of sugar suitable for fermentation into ethanol without reducing fiber quality. Dilute acid hydrolysis process under various conditions has been applied for partial removal of hemicelluloses. The residual materials were pulped using soda-AQ process. The separation of hemicelluloses is optimized to protect the paper strength properties.
The revised Piper Fatigue Scale: psychometric evaluation in women with breast cancer. (1998)

As fatigue is acknowledged to be the most frequent symptom experienced by patients with cancer, accurate measurement and assessment is essential to advance not only the science of fatigue but, most importantly, to evaluate the efficacy of intervention strategies on patient and family outcomes.
Monitoring death and cancer in children born to HIV-infected women in England and Wales: use of HIV surveillance and national routine data (2007)

There may be long-term adverse health effects of in-utero antiretroviral therapy exposure. Data on children reported through national HIV surveillance were linked to routinely collected cancer and death data: a process known as "flagging". Ninety-five per cent (2612) of reported children born in 2001-2004 in England or Wales who were uninfected or of indeterminate infection status were flagged. By the end of 2005, no cancers and 14 deaths (three uninfected and 11 indeterminate) had been notified.
Saliva test could diagnose cancers (2000)

Looking for mitochondrial genetic mutations in bodily fluid could be a promising new way to detect cancers. David Sidransky and his team from Johns Hopkins University School of Medicine in Baltimore, Maryland, have discovered that genetic mutations in mitochondrial cells from cancers are highly prevalent and easily detectable in urine, sputum, and bronchial secretions.

Professor Sidransky believes that this observation could provide a powerful molecular marker for non-invasive detection of cancer (Science 2000;287:2017-9).

Mitochondrial DNA is derived from …

A hybrid filtering approach for storage optimization in main-memory cloud database (2015)

Enterprises and cloud service providers face dramatic increase in the amount of data stored in private and public clouds. Thus, data storage costs are growing hastily because they use only one single high-performance storage tier for storing all cloud data. There’s considerable potential to reduce cloud costs by classifying data into active (hot) and inactive (cold). In the main-memory databases research, recent works focus on approaches to identify hot/cold data. Most of these approaches track tuple accesses to identify hot/cold tuples. In contrast, we introduce a novel Hybrid Filtering Approach (HFA) that tracks both tuples and columns accesses in main-memory databases. Our objective is to enhance the performance in terms of three dimensions: storage space, query elapsed time and CPU time. In order to validate the effectiveness of our approach, we realized its concrete implementation on Hekaton, a SQL’s server memory-optimized engine using the well-known TPC-H benchmark. Experimental results show that the proposed HFA outperforms Hekaton approach in respect of all performance dimensions. In specific, HFA reduces the storage space by average of 44–96%, reduces the query elapsed time by average of 25–93% and reduces the CPU time by average of 31–97% compared to the traditional database approach.
Security Administration in an Open Networking Environment (1995)

As networking technologies evolve and business needs change, traditionally isolated and secure communication networks are giving way to more open computing environments. Security, network and systems administrators must therefore concern themselves not only with firewall and boundary security, but also with individual system security. Security administration in a large open network is a challenging assignment and requires a combination of auditing, assessment and compliance mechanisms. For very large networks, automation is another variable which is critical to consider in this equation. There are several tools available to assess the security of networks and systems; however, there are few freely available solutions for addressing the problems that these analysis tools detect.

This paper describes the changing network security paradigm and discusses what tools are available for identifying security vulnerabilities in an open network environment. It goes on to state the problem that we faced at Sun and describes the suite of tools that we have designed and implemented as a solution, focusing on the automation of system security assessment and compliance. Finally, SunSWAT, the Sun Security Weakness Attack Tool, is introduced and its evolution from a single shell script designed to respond to the results of a network security audit, into a system for improving system security, implementing enterprise security standards and auditing to those standards, is discussed.
Composite Bacterial Hopanoids and Their Microbial Producers across Oxygen Gradients in the Water Column of the California Current (2013)

Hopanoids are pentacyclic triterpenoid lipids produced by many prokaryotes as cell membrane components. The structural variations of composite hopanoids, or bacteriohopanepolyols (BHPs), produced by various bacterial genera make them potentially useful molecular biomarkers of bacterial communities and metabolic processes in both modern and ancient environments. Building on previous work suggesting that organisms in low-oxygen environments are important contributors to BHP production in the marine water column and that there may be physiological roles for BHPs specific to these environments, this study investigated the relationship between trends in BHP structural diversity and abundance and the genetic diversity of BHP producers for the first time in a low-oxygen environment of the Eastern Tropical North Pacific. Amplification of the hopanoid biosynthesis gene for squalene hopene cyclase (sqhC) indicated far greater genetic diversity than would be predicted by examining BHP structural diversity alone and that greater sqhC genetic diversity exists in the marine environment than is represented by cultured representatives and most marine metagenomes. In addition, the genetic relationships in this data set suggest microaerophilic environments as potential "hot spots" of BHP production. Finally, structural analysis of BHPs showed that an isomer of the commonly observed BHP bacteriohopanetetrol may be linked to a producer that is more abundant in low-oxygen environments. Results of this study increase the known diversity of BHP producers and provide a detailed phylogeny with implications for the role of hopanoids in modern bacteria, as well as the evolutionary history of hopanoid biosynthesis, both of which are important considerations for future interpretations of the marine sedimentary record.
Adaptive Codebook Selection for Limited Feedback MIMO Beamforming Systems (2009)

A combined codebook for limited feedback multi-input multi-output (MIMO) beamforming system is proposed, where two grassmannian codebooks are combined together to make a set of new codebooks, and from which to choose the codebook for quantification. The codebook selection information is implied in the feedback codeword indexes, thus we can to switch the codebook adaptively. Simulation results show that this method can be used to any channel models, and at the same BER, this method can reduce the feedback rate compare to grassmannian codebooks in correlated channels.
Keyword extraction for text categorization (2005)

Text categorization (TC) is one of the main applications of machine learning. Many methods have been proposed, such as Rocchio method, Naive bayes based method, and SVM based text classification method. These methods learn labeled text documents and then construct a classifier. A new coming text document's category can be predicted. However, these methods do not give the description of each category. In the machine learning field, there are many concept learning algorithms, such as, ID3 and CN2. This paper proposes a more robust algorithm to induce concepts from training examples, which is based on enumeration of all possible keywords combinations. Experimental results show that the rules produced by our approach have more precision and simplicity than that of other methods.
Fast image segmentation based on K-Means clustering with histograms in HSV color space (2008)

A fast and efficient approach for color image segmentation is proposed. In this work, a new quantization technique for HSV color space is implemented to generate a color histogram and a gray histogram for K-Means clustering, which operates across different dimensions in HSV color space. Compared with the traditional K-Means clustering, the initialization of centroids and the number of cluster are automatically estimated in the proposed method. In addition, a filter for post-processing is introduced to effectively eliminate small spatial regions. Experiments show that the proposed segmentation algorithm achieves high computational speed, and salient regions of images can be effectively extracted. Moreover, the segmentation results are close to human perceptions.
Defects of Insulin Action on Fatty Acid and Carbohydrate Metabolism in Familial Combined Hyperlipidemia (1997)

Familial combined hyperlipidemia (FCHL) is a common cause of premature myocardial infarction, but its metabolic basis is unknown. Insulin resistance has been suggested in some patients by the presence of fasting hyperinsulinemia. We studied insulin action on carbohydrate and fatty acid metabolism in FCHL patients and healthy control subjects by a two-step euglycemic, hyperinsulinemic clamp. During low-dose insulin infusion, steady-state nonesterified fatty acids (NEFAs) were higher in patients than in control subjects (0.36 mmol/L [95% confidence limits, 0.19, 0.53] versus 0.19 mmol/L [0.10, 0.28]; P = .05). The ratio of steady-state to basal NEFAs was increased by 88% in patients compared with control subjects (P = .005). During high-dose insulin infusion, insulin sensitivity for peripheral glucose disposal was reduced by 60% in FCHL patients compared with control subjects (P = .03). Hepatic glucose production at baseline and during the clamp was similar in the two groups. In multiple regression analysis, increased upper-body fat in the patient group accounted for the impairment of insulin-mediated glucose disposal but did not influence the defect in insulin-mediated NEFA suppression in the FCHL patients. This defect in fatty acid metabolism may be a primary defect in FCHL that contributes to abnormalities in the secretion and composition of lipoproteins in this disorder. Direct study of this defect may facilitate genetic analysis of this disorder.
A chemically selective laser ion source for on-line mass separation (1992)

Laser resonance ionization has been applied to ionize radioactive atoms released from thick ISOLDE/CERN targets. Laser light from pulsed dye lasers with a high repetition rate (10 kHz) was used for stepwise excitation and ionization. By this method, efficiency as well as the selectivity of the target/ion source system could be improved. In a series of off-line and on-line studies, the resonance ionization of elements with different ionization potentials, such as Yb (Ei=6.2 eV), Tm (Ei=5.8 eV) and Sn (Ei=7.3 eV), was investigated. For Yb, photoionization efficiencies of up to 15% have been measured. An efficiency of 0.2% was obtained for Sn at the on-line separator ISOLDE-3. However, this value can be improved by about two orders of magnitude using a transition to an autoionizing state at 59 375.9 cm−1.

A supervised learning approach for imbalanced data sets (2008)

This paper presents a new learning approach for pattern classification applications involving imbalanced data sets. In this approach, a clustering technique is employed to resample the original training set into a smaller set of representative training exemplars, represented by weighted cluster centers and their target outputs. Based on the proposed learning approach, four training algorithms are derived for feed-forward neural networks. These algorithms are implemented and tested on three benchmark data sets. Experimental results show that with the proposed learning approach, it is possible to design networks to tackle the class imbalance problem, without compromising the overall classification performance.
[Nephropathy in patients with mixed connective tissue disease]. (1994)

The first report of mixed connective tissue disease (MCTD) was described that nephropathy was rare complication of the patients with MCTD. Recently, some authors reported that the nephropathy was 25-50% of patients with MCTD. This report investigated the histopathological findings of patients with MCTD. This study was conducted on 17 patients associated with MCTD. In clinical features, there were six of nephrotic syndrome and two of hematuria and proteinuria. They were normal renal function, expect for one case (case MF). In pathological findings, there were four of membranous nephropathy, two of mesangial proliferative glomerulonephritis, including one of IgA nephropathy, and 11 of minor glomerular abnormality. Three cases translated to systemic lupus erythematosus (SLE) during follow-up period (1 to 5 years). They had hypocomplementemia and membranous nephropathy in common. In conclusion, the nephropathy is not rare complication in patients with MCTD. Sex of the 17 patients (35.3%) with MCTD have nephropathy. MCTD cases with immune-complex glomerulonephritis are likely to transit from MCTD to SLE.
BEER DRINKING AND ITS EFFECT ON URIC ACID (1984)

This study attempted to simulate the drinking habits of gout patients. Beer or squash was drunk over a 4-hour period on two successive days by five gouty and five normouricaemic men. Serum lactate increased with beer and squash, but elevation of plasma uric acid was confined to beer drinking. Urate clearance increased with both beverages, but 24-hour uric acid excretion was accentuated only by beer. The purine content of several beers was measured and the principal constituent found to be guanosine, which is probably the most readily absorbed dietary purine. It was concluded that the hyperuricaemic effect of beer was mediated by the digestion of purines contained by the beer and by an effect of ethanol on uric acid synthesis. There was no evidence that beer taken in usual quantities reduced the renal excretion of uric acid.
Principles of Rotationplasty (2012)

Rotationplasty is a reconstructive, limb-sparing option for management of lower extremity bone deficiency. This technique involves an intercalary resection, followed by 180° rotation of the distal limb to allow the ankle to function as a knee joint when it is fitted with a modified below-knee prosthesis. Gait analysis and functional outcome studies have reported favorable results with rotationplasty compared with those of above-knee amputation. Moreover, patient satisfaction with rotationplasty is higher than with other limb salvage procedures. The primary drawback of this procedure is patient acceptance of the limb's appearance.
Unified approach to the design of quadrature-mirror filters (2002)

A unified approach to the design of linear- and nonlinear-phase QMFs is developed. Formulated as an optimization problem, the design procedure is shown to translate into an eigenvalue-eigenvector problem. To find the optimal filter an algorithm is presented, which typically converges in a few tens of iterations. The flexibility of our design procedure permits several practical extensions to be made readily. These are (a) inclusion of frequency-weighted stop band energy criteria, and (b) inclusion of finite word-length constraints. We have successfully used our filters to applications such as image coding and analysis; here, their use in wavelet-series analysis of oceanographic data is demonstrated.
