How to Architect a Query Compiler (2016)

This paper studies architecting query compilers. The state of the art in query compiler construction is lagging behind that in the compilers field. We attempt to remedy this by exploring the key causes of technical challenges in need of well founded solutions, and by gathering the most relevant ideas and approaches from the PL and compilers communities for easy digestion by database researchers. All query compilers known to us are more or less monolithic template expanders that do the bulk of the compilation task in one large leap. Such systems are hard to build and maintain. We propose to use a stack of multiple DSLs on different levels of abstraction with lowering in multiple steps to make query compilers easier to build and extend, ultimately allowing us to create more convincing and sustainable compiler-based data management systems. We attempt to derive our advice for creating such DSL stacks from widely acceptable principles. We have also re-created a well-known query compiler following these ideas and report on this effort.
The topography of the surface of potato virus X: tritium planigraphy and immunological analysis (1992)

Thermally activated tritium atoms were used to probe the surface topography of the coat protein of potato virus X (PVX) potexvirus. The accessibility profile of amino acid residues in the polypeptide chain was determined from data on the intramolecular distribution of tritium label in the PVX coat protein. Tryptic peptides T1 and T2, as well as parts of peptides T3 and T5, from the PVX particles were all located in the N-terminal region of the PVX coat protein and were accessible to tritium labelling, whereas the C-terminal region of the coat protein was practically inaccessible to it. Indirect ELISA and immunoblotting with two PVX-specific monoclonal antibodies confirmed that the N terminus of the coat protein (residues 1 to 56) was exposed on the virus surface, and furthermore that this region forms a highly immunogenic virus-specific antigenic region. The data obtained support the spatial model of PVX, in which the N-terminal amino acids of the coat protein are exposed at the particle surface, and the C-terminal region is buried in the particle. The spatial organization of the PVX coat proteins differs from the model proposed for other filamentous plant viruses such as potyviruses and tobamoviruses where both the N and C termini of the coat protein are located at the particles' surface.
Debugging in a distributed world: observation and control (2002)

Debugging distributed programs is considerably more difficult than debugging sequential programs. We address issues in debugging distributed programs and provide a general framework for observing and controlling a distributed computation and its applications to distributed debugging. Observing distributed computations involves solving the predicate detection problem. We present the main ideas involved in developing efficient algorithms for predicate detection. Controlling distributed computations involves solving the predicate control problem. Predicate control may be used to restrict the behavior of the distributed program to suspicious executions. We also present an example of how predicate detection and predicate control can be used in practice to facilitate distributed debugging.

Modeling, simulation and analysis of an uninterruptible power supply (2002)

The uninterruptible power supply (UPS) has become an integral part of modern computer and communication systems to assure a continued and reliable operation by providing an uninterruptible power to such equipment. Various topologies have come to the fore recently with the advent of high frequency switching techniques. This paper considers such a high frequency operated UPS system and it is modeled, simulated and analyzed to provide insight and information for design studies. A framework for the software simulation of a class of UPS is proposed in this paper and its implementation results are given and discussed. The software structure and its implementation are included in the paper. The software is built on a modular basis to enable the simulation of various topologies of UPS that are in vogue and that may emerge in the future.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

When reduced ${\mathrm{TiO}}_{2}(110)$ single crystals are oxidized at moderate temperatures (470--660 K), the surfaces restructure. Interstitial Ti atoms from the bulk diffuse to the surface where they react with gaseous oxygen and form new, added ${\mathrm{TiO}}_{2}$ layers. These are characterized by three structural elements: small $(1\ifmmode\times\else\texttimes\fi{}1)$ islands, irregular networks of pseudohexagonal rosettes, and [001]-oriented strands. The strands exhibit the same structural characteristics as the $(1\ifmmode\times\else\texttimes\fi{}2)$ surface reconstruction, which forms upon annealing at higher temperatures. Atomic-resolution scanning tunneling microscopy images of the strands are consistent with the added-${\mathrm{Ti}}_{2}{\mathrm{O}}_{3}$-row model. UHV annealing of oxygen-restructured surfaces smooths the surfaces and converts the rosette networks into strands and finally into regular $(1\ifmmode\times\else\texttimes\fi{}1)$ terraces. The composition of these oxygen-induced phases is quantified using ${}^{18}{\mathrm{O}}_{2}$ gas in combination with low-energy ${\mathrm{He}}^{+}$ ion scattering measurements. Dynamic processes for the conversion from rosette networks into $(1\ifmmode\times\else\texttimes\fi{}2)$ strands and ultimately into $(1\ifmmode\times\else\texttimes\fi{}1)$ terraces are discussed.
Microstructure and mechanical properties of Sn–Cu alloys for detonating and explosive cords (2017)

To develop alloys as the substitute of Pb-based alloys for cladding materials in detonating and explosive cords, the materials requirement was analysed and Sn–Cu based alloys were selected as potential candidates. Four alloys including Sn–0.3 wt-%Cu, Sn–0.5 wt-%Cu, Sn–0.7 wt-%Cu, and Sn–1.0 wt-%Cu were prepared by casting and rolling. Microstructures of as-cast Sn–Cu alloys comprised Sn solutions with Cu6Sn5 intermetallic in the matrix. The as-rolled hypoeutectic Sn–Cu alloys (0.3–0.5 wt-%Cu) offered the yield strength from 26.1 to 31.9 MPa, UTS from 30.1 to 34 MPa and elongation from 86.4 to 87.5%, which were found to be appropriate for detonating and explosive cords. Particularly, the Sn–Cu alloys exhibited strain softening behaviour under tensile stress, which will benefit cladding manufacture and subsequent processing after assembly with high-energy explosive materials.

Inhibition of β-glucuronidase by natural glucuronides of<i>Kampo</i>, medicines using glucuronide of SN-38 (7-ethyl-10-hydroxycamptothecin) as a substrate (1993)

1. 7-Ethyl-10-[4-(piperidino)-1-piperidino] carbonyloxycamptothecin (CPT-11), a potent anticancer agent currently under development for clinical use, is metabolized in vivo to 7-ethyl-10-hydroxycamptothecin (SN-38), which is subsequently conjugated to 7-ethyl-10-hydroxycamptothecin glucuronide (SN-38-glucuronide). The SN-38-glucuronide was hydrolysed by beta-glucuronidase from E. coli to aglycones and glucuronic acid. 2. Four purified natural glucuronides including baicalin, wogonoside, luteolin-3'-glucuronide, and glycyrrhizin, inhibited beta-glucuronidase using SN-38-glucuronide as substrate. The inhibition potencies of these natural glucuronides toward beta-glucuronidase were similar to that of saccharic acid 1,4-lactone. 3. These results indicate that plant materials of Kampo (Japanese herbal) medicines containing these glucuronides could be used in vivo to decrease the enterohepatic circulation of SN-38 and possibly that of other drugs.
Editorial: Irritable Bowel Syndrome and the Elusive Mast Cells (2012)

Irritable bowel syndrome (IBS) is the most common condition seen by gastroenterologists. It presents with alternating symptoms of bowel dysfunction that often worsens with stress. The cause of these symptoms eludes investigators and many attempts have been made to discover an underlying pathology. This is a daunting task since symptoms come and go, and change characteristics. Furthermore, the pathology of IBS is unlikely to be identical in all patients. In addition, all symptoms and all features studied thus far have a strong overlap with healthy volunteers. Elsewhere in this issue, Braak et al. report a well-designed clinical investigation in patients with IBS and come to the conclusion that IBS is not characterized by mast cell or other immune cell proliferation, but by immune dysregulation in the colon. Is this the final answer?

[Determination of 15-methyl prostaglandin F2a by derivatization high pressure liquid chromatography]. (1982)

After conversion to their p-bromophenacyl esters at room temperature, the epimerit 15(R) and 15 (S) methyl prostaglandin F_(2α) were completely separated by HPLC on a microparticulate silica gel column (Perkin-Elmer Silica A prepacked) using a mixture of chloroform and ethyl acetate (1:1) as the eluent. The derivatives were detected by UV spectrophotometer at 257nm. The ratio of the epimers in a number of samples were accurately determined by this method. Several samples were quantitatively determined using pure 15 (S) prostagiandin F_(2α) p-bromophenacyl ester (mp 85～86 C) as the external standard which was prepared in our work. Other prostaglandins including PGF_(2a), PGE_1, PGE_2 and ω-ethyl-13-dehydro PGF_(2a) were also determined by the same method and their relative retention time to 15 (S) PGF_(2a) p-bromophenacyl ester were given. The method proposed was suitable for accurate determination of 15 (R) and 15 (S) methyl prostaglandin F_(2a) and their relative contents in samples.
Big Data Analytics for Fault Detection and its Application in Maintenance (2016)

Big Data analytics has attracted intense interest recently for its attempt to extract information, knowledge and wisdom from Big Data. In industry, with the development of sensor technology and Information &amp; Communication Technologies (ICT), reams of high-dimensional, streaming, and nonlinear data are being collected and curated to support decision-making. The detection of faults in these data is an important application in eMaintenance solutions, as it can facilitate maintenance decision-making. Early discovery of system faults may ensure the reliability and safety of industrial systems and reduce the risk of unplanned breakdowns. Complexities in the data, including high dimensionality, fast-flowing data streams, and high nonlinearity, impose stringent challenges on fault detection applications. From the data modelling perspective, high dimensionality may cause the notorious “curse of dimensionality” and lead to deterioration in the accuracy of fault detection algorithms. Fast-flowing data streams require algorithms to give real-time or near real-time responses upon the arrival of new samples. High nonlinearity requires fault detection approaches to have sufficiently expressive power and to avoid overfitting or underfitting problems. Most existing fault detection approaches work in relatively low-dimensional spaces. Theoretical studies on high-dimensional fault detection mainly focus on detecting anomalies on subspace projections. However, these models are either arbitrary in selecting subspaces or computationally intensive. To meet the requirements of fast-flowing data streams, several strategies have been proposed to adapt existing models to an online mode to make them applicable in stream data mining. But few studies have simultaneously tackled the challenges associated with high dimensionality and data streams. Existing nonlinear fault detection approaches cannot provide satisfactory performance in terms of smoothness, effectiveness, robustness and interpretability. New approaches are needed to address this issue. This research develops an Angle-based Subspace Anomaly Detection (ABSAD) approach to fault detection in high-dimensional data. The efficacy of the approach is demonstrated in analytical studies and numerical illustrations. Based on the sliding window strategy, the approach is extended to an online mode to detect faults in high-dimensional data streams. Experiments on synthetic datasets show the online extension can adapt to the time-varying behaviour of the monitored system and, hence, is applicable to dynamic fault detection. To deal with highly nonlinear data, the research proposes an Adaptive Kernel Density-based (Adaptive-KD) anomaly detection approach. Numerical illustrations show the approach’s superiority in terms of smoothness, effectiveness and robustness.

Techniques of assessing air pollution damage to paints (1974)

In this study, research was concerned primarily with the development of test methods that are sufficiently sensitive to detect the initial degradation of selected exterior coatings exposed to various pollutant‐containing environments. The test methods employed in generating dose response data included erosion rates, attenuated total reflectance (ATR), gloss and sheen, surface roughness, tensile strength and scanning election microscopy. Five commercially important paint systems were selected for characterizations including an oil house paint, latex coating, an alkyd industrial maintenance coating, a coil coating and an automotive refinish lacquer. The properties of the coating systems were determined periodically consequent to ‘short term’ exposure at four exterior locations and to various pollutant‐containing environments under controlled, but accelerated conditions in an Atlas Xenon Arc Weather‐Ometer® Model 600WR12. The test sites for the former ‘short term’ exterior study were located at Leeds (north central), North Dakota; Los Angeles, California; Chicago (Research Center), Illinois and Valparaiso, Indiana. These sites represent a ‘clean’ rural environment, a high O3 environment, a high SO2 environment, and a relatively high O3 environment plus a moderate SO2 environment, respectively. In the accelerated laboratory exposure study, five enenvironmental pollutant conditions were employed in the Weather‐Ometer including a zero pollutant, 0·1ppm and 1·0ppm SO2 and 0·1ppm or 1·0ppm O3 level. The zero pollutant condition represents the control (clean air) with 0·1 ppm of each pollutant type considered representative of the levels frequently reached in polluted cities. The 1·0ppm levels represent a highly polluted (industrial) site.
Fe and Ag supported on activated carbon as an effective adsorbent for 2,4-dichlorophenoxylacetic acid treatment: a theoretical study (2021)

Extended tight-binding quantum chemical method (GFN2-xTB) was performed to investigate the adsorption of 2,4-dichlorophenoxylacetic acid (2,4-D) on activated carbon (AC) and AC modified by Fe or Ag (AC-M). Electronic properties of the studied systems were estimated via vertical ionisation potential, vertical electron affinity, and global electrophilicity index. Adsorption energy, population analysis, and geometrical parameters were calculated to clarify the adsorption ability of AC and AC-M. The results indicated that the introduction of metal atoms to AC substantially enhanced the adsorption ability for 2,4-D. The adsorption mechanism changed from physical adsorption (on AC) to chemisorption (on AC-M). The influence of different solvents (water, methanol, and acetonitrile) on the adsorption process was studied via an Analytical linearized Poisson-Boltzmann algorithm.
A pilot study of ICG laser therapy of <i>acne vulgaris</i>: Photodynamic and photothermolysis treatment (2003)

Based on the concept that hair follicle, especially sebaceous gland, can be intensively and selectively stained by ICG due to dye diffusion through pilosebaceous canal and its fast uptake by living microorganisms, by vital keratinocytes of epithelium of the canal and sebaceous duct, and by rapidly proliferating sebocytes, new technologies of soft and thermal acne lesions treatment that could be used in clinical treatment of acne were proposed.
Mini-Annular Phased Array for Limb Hyperthermia (1986)

The design concepts of a thin-shell cylindrical or annular phased-array of conformal strip radiators is shown to be suitable for deep heating of phantoms simulating the limbs of the human body. The Mini-Annular Phased Array (MAPA) is presently under clinical investigation for treatment of cancer of the limbs at a limited number of institutions. The effect of frequency and tissue conductivity is shown under simulated conditions for a few sample power-density patterns illustrating the deep focusing of the radiated EM fields. These are compared to a numerical model pattern which can be used to estimate the patterns in varying diameter limbs. The effect of offsetting the limb within the array to steer pattern of heat deposition has also been shown to produce desirable asymmetrical patterns.
Abstract B58: Gene expression study on a highly aggressive canine transmissible venereal tumor of a NOD/SCID mice model (2010)

Abstract We have set up a xenograft NOD/SCID mice model bearing canine transmissible venereal tumor (CTVT) (designated as MCTVT). In addition to the similarity of the tumor cells between CTVT and MCTVT, the insertion of the specific gene fragment in the 5′ end of c-myc characteristic for a CTVT cell was also confirmed in MCTVT. However, as inoculating back to dogs, the MCTVT showed a much more aggressive growth and much higher metastatic frequency than a common CTVT. The goal of this research was to explore the gene expression differences between CTVT and MCTVT, and tried to delineate the mechanisms of their growth pattern differences. The differential gene expressions between the 2 tumors were studied using Affymetrix. Studied by hierarchical analysis and filtering the differential expressed genes by 2-fold method, we have found 105 genes significantly up-regulated and 37 down-regulated in MCTVT comparing to CTVT. Many of these genes were previously published to be involved in the areas such as malignant candidate genes, important biological processes, tumor development and immune modulation. We then used Real-Time RT-PCR to study the top 30 up-regulated genes. Three genes (APOC1, MMP1 and KMO) were further confirmed that were significantly up-regulated in MCTVT. The three genes were then tested in 22 spontaneous canine mammary gland tumors (CMGT) using Real-Time RT-PCR, the results indicated that two out of the three up-regulated genes discriminated malignant from benign CMGT and their gene expression was significantly higher in grades 4 and 5 malignant CMGT than those from lower grade tumors. We are currently studying the activities of KMO in association with the tumor cell growth. This study presented the novel candidate gene (KMO) that might associate with the malignant growth of tumor cells and has potential to be used as a biological marker to differentiate degrees of malignancy.
