Pattern Matching for Program Generation: A User Manual (1998)

The Anticipatory Optimization Generation (AOG) system is built to generate custom programs using largescale, programmatic transformations (versus pure pattern-based transformations) that operate on Abstract Syntax Trees (ASTs). Because of the scale of the AOG transformations and the often-complex program reorganizations that they enable, the transformations must operate on the low-level physical formats of the ASTs and simultaneously accommodate high degrees of variation in the ASTs. However, both the physical details of and variations within an AST are irrelevant to the AOG system in the same sense that both the physical details of and variations within a database format are irrelevant to a database management system. In both cases, only the logical structure is relevant. Database management systems introduce logical schemas to hide the details and variations in the format of their databases. Similarly, the AOG pattern matcher introduces a pattern notation that performs the analogous service for ASTs. It hides the details of and variations within an AST from the large-scale transformations that must operate on the AST and thereby reduces the complexity of the transformation code. The pattern notation is embedded in the Lisp language and provides a set of Prolog-like operators for performing complex matching and inference logic. The operators include analogs to the Prolog operators and, or, not, mark, cut, bind, is, succeed, fail, prove, and rule definition (i.e., &lt;-). They also include a number of more specialize operators such as operators that span sections of an AST, bind the remainder of a list, perform top-down and bottom-up tree searches, rename local variables, use dynamically computed variable values as patterns, invoke and use rule sets, navigate object struct...
Bridging the gaps: joining information sources with Splunk (2010)

Supercomputers are composed of many diverse components, operated at a variety of scales, and function as a coherent whole. The resulting logs are thus diverse in format, interrelated at multiple scales, and provide evidence of faults across subsystems. When combined with system configuration information, insights on both the downstream effects and upstream causes of events can be determined. However, difficulties in joining the data and expressing complex queries slow the speed at which actionable insights can be obtained. Effectively connecting data experts and data miners faces similar hurdles. This paper describes our experience with applying the Splunk log analysis tool as a vehicle to combine both data, and people. Splunk’s search language, lookups, macros, and
A novel microarray approach reveals new tissue-specific signatures of known and predicted mammalian microRNAs (2007)

Microarrays to examine the global expression levels of microRNAs (miRNAs) in a systematic in-parallel manner have become important tools to help unravel the functions of miRNAs and to understand their roles in RNA-based regulation and their implications in human diseases. We have established a novel miRNA-specific microarray platform that enables the simultaneous expression analysis of both known and predicted miRNAs obtained from human or mouse origin. Chemically modified 2'-O-(2-methoxyethyl)-(MOE) oligoribonucleotide probes were arrayed onto Evanescent Resonance (ER) microchips by robotic spotting. Supplementing the complementary probes against miRNAs with carefully designed mismatch controls allowed for accurate sequence-specific determination of miRNA expression profiles obtained from a panel of mouse tissues. This revealed new expression signatures of known miRNAs as well as of novel miRNAs previously predicted using bioinformatic methods. Systematic confirmation of the array data with northern blotting and, in particular, real-time PCR suggests that the described microarray platform is a powerful tool to analyze miRNA expression patterns with rapid throughput and high fidelity.
Analysis of regenerative fuel cells (1982)

The concept of a rechargeable fuel cell (RFC) system is considered. A newer type of rechargeable battery, the nickel hydrogen (Ni-H2) battery, is also evaluated. A review was made of past studies which showed large variations in weight, cost, and efficiency. Hydrogen-bromine and hydrogen-chlorine regenerable fuel cells were studied, and were found to have a potential for higher energy storage efficiency then the hydrogen-oxygen system. A reduction of up to 15 percent in solar array size may be possible as a result. These systems are not yet developed, but further study of them is recommended.
Decontamination System Utilizing Hydrogen Peroxide, UV Light and Catalytic Surfaces (1992)

A decontamination process utilizing condensing 50% hydrogen peroxide vapor and 254 nm ultraviolet (UV) light was tested in the laboratory utilizing several agent simulants. The UV light photolyzes hydrogen peroxide, producing hydroxyl radicals which react rapidly with most organic molecules. The rate of reaction is determined mostly by the solubility of the agent simulant in the water-like hydrogen peroxide condensate. The insecticide Dimethoate, a simulant for Agent VX, is effectively destroyed due to relatively high water solubility. Phenyl half-mustard and Malathion are much less soluble in water, and only partial decontamination was achieved. Material damage is a major concern. Several conformal coatings and two paint systems were tested. Some performed well, but others failed rapidly.
Aspirin and the Prevention of Colorectal Cancer (2003)

Awareness of the substantial morbidity and mortality attributable to colorectal cancer has focused attention on early detection and prevention through screening and on other strategies such as chemoprevention. Among several agents under evaluation, aspirin appears to have the inside track. Could aspirin reduce the burden of disease associated with the second-leading cause of cancer-related death in the United States?A protective effect of aspirin is biologically plausible. Aspirin works in part through the inhibition of cyclooxygenase-2, an enzyme that is found in colorectal cancer tissue. Epidemiologic studies have shown a consistent 40 to 50 percent reduction in the risk of . . .
A Public Keys Based Architecture for P2P Identification, Content Authenticity and Reputation (2009)

In the classic use of P2P, e.g. file sharing, there is no concern about persistent peer identification, peer and content reputation and content authenticity. Security proposals currently found in technical literature try to adapt techniques from client-server architecture to P2P environments, which it is not the most appropriate approach. This work proposes applying public keys to identify peers. It allows creating a persistent identification scheme, without losing anonymity, even in a self-managed environment as P2P. Also, it applies digital signature to provide authenticity to the P2P content and to guarantee non-repudiation in the content transfer. In order to provide credibility to the non-certified content and public keys a reputation mechanism is applied. We have developed a prototype to show the benefits of this approach.
FRAMES: Software tools for modeling, rendering and animation of 3D scenes (1987)

FRAMES is a set of flexible software tools, developed for the UNIX programming environment, that can be used to generate images and animation of 3D scenes. In FRAMES, each stage of the image-rendering pipeline is assigned to a UNIX System filter. The following is a typical FRAMES pipe sequence where each filter performs a task implied by its name:cat scene.frm|euclid|mover|shade|camera|abufFRAMES was designed to be easy to use, to permit flexible experimentation with new ideas in image rendering and geometric modeling, to allow distribution of different parts of the rendering pipeline to different processors, and to specify images in a common format for display on a variety of devices.The user communicates with FRAMES via a command language. This language is extended whenever a software developer needs to incorporate a new idea into the system by adding new commands. Data flowing through the pipeline is modified by a collection of filter programs and passed through the pipe in text or binary format.The modular and pipe-based nature of FRAMES allows for multi/parallel processor implementations and device independence. FRAMES has generated images on a local-area network of minicomputers (each filter runs on a different processor) and on a 64-processor hypercube machine (one filter runs on 64 processors). Applications of FRAMES have ranged from reconstruction of neurons from serial sections to rendering of antialiased octree objects with subpixel detail.
Anomaly detection in the maritime domain (2008)

Defence R&D Canada is developing a Collaborative Knowledge Exploitation Framework (CKEF) to support the analysts in efficiently managing and exploiting relevant knowledge assets to achieve maritime domain awareness in joint operations centres of the Canadian Forces. While developing the CKEF, anomaly detection has been clearly recognized as an important aspect requiring R&D. An activity has thus been undertaken to implement, within the CKEF, a proof-of-concept prototype of a rule-based expert system to support the analysts regarding this aspect. This expert system has to perform automated reasoning and output recommendations (or alerts) about maritime anomalies, thereby supporting the identification of vessels of interest and threat analysis. The system must contribute to a lower false alarm rate and a better probability of detection in drawing operator's attention to vessels worthy of their attention. It must provide explanations as to why the vessels may be of interest, with links to resources that help the operators dig deeper. Mechanisms are necessary for the analysts to fine tune the system, and for the knowledge engineer to maintain the knowledge base as the expertise of the operators evolves. This paper portrays the anomaly detection prototype, and describes the knowledge acquisition and elicitation session conducted to capture the know-how of the experts, the formal knowledge representation enablers and the ontology required for aspects of the maritime domain that are relevant to anomaly detection, vessels of interest, and threat analysis, the prototype high-level design and implementation on the service-oriented architecture of the CKEF, and other findings and results of this ongoing activity.
Strain-Promoted Alkyne Azide Cycloaddition for the Functionalization of Poly(amide)-Based Dendrons and Dendrimers (2010)

Functionalization of a poly(amido)-based dendron with ethylene glycol chains (PEG) using copper-catalyzed alkyne azide cycloaddition (CuAAC) afforded dendrons with significant levels of copper contaminations, preventing the use of such materials for biological applications. We suggest that the presence of amide, PEG, and triazole functional groups allows for copper complexation, thereby preventing the separation of the copper catalyst from the final dendron. To minimize this problem, synthetic variations on CuAAC including the addition of "click" additives for copper sequestering as well as the use of copper wire as the copper source were investigated. None of these strategies, however, resulted in copper-free products. In contrast, we developed a copper-free strain-promoted alkyne azide cycloaddition (SPAAC) strategy that functionalized poly(amide)-based dendrons and dendrimers with PEG chains quantitatively under mild reaction conditions without any metal contamination. The SPAAC products were characterized by (1)H and (13)C NMR, 2D HSQC and COSY NMR, mass spectrometry, and elemental analysis. This is the first report on the use of SPAAC for dendrimer functionalization, and the results obtained here show that SPAAC is an important tool to the dendrimer and more general biomaterials community for the functionalization of macromolecular structures due to the mild and metal-free reaction conditions, no side products, tolerance toward functional groups, and high yields.
Domain Adaptive Information Extraction Using Link Grammar and WordNet (2007)

Nowadays, people want to extract variety of information from on line texts. As more and more text becomes available on-line, there is emergent need for systems that extract information automatically from text corpus. One of the principle challenges of information extraction is the efficient customization of a system to a new domain. Adapting an information extraction system to a new domain entails the construction of a new set of extraction rules. Many recent information extraction systems have ignored the tedious and time-consuming nature of that process. This paper proposes an alternative approach, which generate candidate extraction rules from untagged text corpus using Link Grammar Parser and filter the final extraction rules using Wordnet and linguistic patterns. The proposed method not only reduces the amount of time and effort required to create an appropriate training corpus but also obviates the need to examine many candidate extraction rules so that the system can easily port well to different domain.
C<sub>60</sub>-Fullerene Monomalonate Adducts Selectively Inactivate Neuronal Nitric Oxide Synthase by Uncoupling the Formation of Reactive Oxygen Intermediates from Nitric Oxide Production (2000)

C(60)-Fullerene monomalonate adducts inactivate selectively the neuronal nitric oxide synthase isoform in a manner completely preventable by the concurrent presence of superoxide dismutase and catalase. This inactivation is time-, fullerene concentration-, and turnover-dependent and is not reversible by dilution. The di(carboxypropan-3-ol)methano-[60]-fullerene (diol adduct) has no effect on NADPH consumption by nNOS as measured in the absence of arginine substrate, but dramatically increases NADPH consumption in the presence of arginine. This fullerene-enhanced NADPH consumption is linked to oxygen as electron acceptor and is accompanied by the increased production of hydrogen peroxide. These effects of fullerene monomalonate adducts are unique to the nNOS isoform and are not observed using either the iNOS or the eNOS isoform. The inhibitory effects of fullerene monomalonate adducts are unaltered and insurmountable by increased concentrations of arginine, tetrahydrobiopterin, or calmodulin. These observations indicate that fullerene monomalonate adducts uncouple in the presence of arginine the formation of reactive oxygen intermediates from NO production by nNOS. These reactive oxygen intermediates dissociate from the enzyme and, acting from solution, inactivate NOS NO forming activity.
Joint estimation of chemical shift and quantitative susceptibility mapping (chemical QSM) (2014)

A joint estimation of fat content and magnetic susceptibility using an iterative chemical shift update was shown to improve image quality and accuracy on QSM images.
Statin-mediated protective effects in the central nervous system: General mechanisms and putative role of stress proteins (2006)

Available data suggest that statins may be of potential therapeutic use in a variety of diseases of the CNS including ischemic stroke, Alzheimer's disease, multiple sclerosis and some forms of retinal and eye diseases. Before general recommendations can be made and specific therapeutic approaches can be developed, more reliable clinical data and studies are required, and possible side effects must be carefully evaluated.
Implication of Mitochondrial Hydrogen Peroxide Generation in Ceramide-induced Apoptosis (1997)

The key events implicated in ceramide-triggered apoptosis remain unknown. In this study we show that 25 microM C6-ceramide induced significant H2O2 production within 60 min, which increased up to 180 min in human myeloid leukemia U937 cells. Inactive analogue dihydro-C6-ceramide had no effect. Furthermore, no H2O2 production was observed in C6-ceramide-treated U937 rho degrees cells, which are mitochondrial respiration-deficient. We also present evidence that ceramide-induced activation of the transcription factors NF-kappaB and AP-1 is mediated by mitochondrial derived reactive oxygen species. Both H2O2 production, transcription factor activation as well as apoptosis could be inhibited by rotenone and thenoyltrifluoroacetone (specific mitochondrial complexes I and II inhibitors) and antioxidants, N-acetylcysteine and pyrrolidine dithiocarbamate. These effects could be potentiated by antimycin A (specific complex III mitochondrial inhibitor). H2O2 production was also inhibitable by ruthenium red, suggesting a role of mitochondrial calcium homeostasis alterations in ceramide-induced oxidative stress. Finally, C6-ceramide had no influence on mitochondrial membrane potential within the first 6 h. Altogether, our study points to reactive oxygen species, generated at the ubiquinone site of the mitochondrial respiratory chain, as an early major mediator in ceramide-induced apoptosis.

Application of a Photochromic Dye in an Automatic Welding Filter (2009)

The main purposes of this study were to select a photochromic dye and to develop an active welding filter with a photochromic layer. A series of functionalized spirobenzopyranoindolins were synthesized and their photophysical and photochemical properties were investigated in a solution using absorption and emission spectroscopy. Time-resolved fluorescence spectroscopy measurements were used to characterize the decays and rate constants of fluorescence emission. One dye was selected as a suitable photoactive compound in automatic welding filters. A model of an active welding filter with a photochromic layer based on 1',3',3'-trimethyl-6-nitrospiro[2H-1-benzopyran-2,2'-indole] (6-nitroBIPS) was developed. The paper presents the results of tests of the filter conducted according to EN standards.
Cloning and Gene Replacement Mutagenesis of a <i>Pseudomonas atlantica</i> Agarase Gene (1988)

An agarase gene (agrA) was isolated by cloning genomic DNA prepared from Pseudomonas atlantica. The agarase activity in recombinant Escherichia coli was found in cell-free culture supernatants and could pass through a 0.45-mum-pore-size membrane separating cells from agar, suggesting that the gene product was exported in E. coli. The enzyme was specific for agar and agarose and did not digest alginate or carrageenan. Mutations generated by transposon mini-Mu d1(lacZ Km) were used to define the agrA coding region, as well as the direction of transcription of the gene. A procedure was developed to produce a P. atlantica agrA mutant. This required construction of an agrA::kan insertion mutation in vitro and subsequent introduction of the defect into the chromosome of P. atlantica by recombinational exchange. Transformation of P. atlantica with plasmids containing agrA::kan utilized a Tris-polyethylene glycol 6000-CaCl(2) treatment for making competent cells. Replacement of wild-type agrA with agrA::kan resulted in loss of agarase activity. Uses of the agrA gene probe and an Agr mutant for environmental studies are discussed.
Mineral dust and cell recovery from the bronchoalveolar lavage of healthy Vermont granite workers. (1985)

We characterized the bronchoalveolar lavage (BAL) from healthy Vermont granite workers to investigate the pulmonary response to a chronic exposure to an injurious agent. Nine granite workers with 4 to 36 yr of employment in the industry and 27 unexposed volunteers were normal by history, physical examination, electrocardiogram, blood count, spirometry, and chest radiograph. Lavage cell recovery and percent neutrophils were not different. Lymphocyte recovery in BAL was increased in the granite-exposed population. Granite dust was present within the majority of alveolar macrophages from granite workers compared with those from control subjects, as determined by polarizing light microscopy and confirmed by scanning electron microscopy with X-ray energy spectrometry. There were no differences in phagocytic function or viability of macrophages from granite workers compared with those from unexposed volunteers. We conclude that in exposed populations, granite dust can be detected and semiquantitated in lavage specimens within the alveolar macrophages, macrophage function is preserved, and the response to this exposure involves an influx of lymphocytes.
Both Plant and Bacterial Nitrate Reductases Contribute to Nitric Oxide Production in <i>Medicago truncatula</i> Nitrogen-Fixing Nodules   (2010)

Nitric oxide (NO) is a signaling and defense molecule of major importance in living organisms. In the model legume Medicago truncatula, NO production has been detected in the nitrogen fixation zone of the nodule, but the systems responsible for its synthesis are yet unknown and its role in symbiosis is far from being elucidated. In this work, using pharmacological and genetic approaches, we explored the enzymatic source of NO production in M. truncatula-Sinorhizobium meliloti nodules under normoxic and hypoxic conditions. When transferred from normoxia to hypoxia, nodule NO production was rapidly increased, indicating that NO production capacity is present in functioning nodules and may be promptly up-regulated in response to decreased oxygen availability. Contrary to roots and leaves, nodule NO production was stimulated by nitrate and nitrite and inhibited by tungstate, a nitrate reductase inhibitor. Nodules obtained with either plant nitrate reductase RNA interference double knockdown (MtNR1/2) or bacterial nitrate reductase-deficient (napA) and nitrite reductase-deficient (nirK) mutants, or both, exhibited reduced nitrate or nitrite reductase activities and NO production levels. Moreover, NO production in nodules was found to be inhibited by electron transfer chain inhibitors, and nodule energy state (ATP-ADP ratio) was significantly reduced when nodules were incubated in the presence of tungstate. Our data indicate that both plant and bacterial nitrate reductase and electron transfer chains are involved in NO synthesis. We propose the existence of a nitrate-NO respiration process in nodules that could play a role in the maintenance of the energy status required for nitrogen fixation under oxygen-limiting conditions.
Root surface conditioning with bone morphogenetic protein-2 facilitates cementum-like tissue deposition in beagle dogs (2010)
