Potential for Occupational Exposure to Engineered Carbon-Based Nanomaterials in Environmental Laboratory Studies (2009)

Engineered nanomaterials can become airborne when mixed in solution by sonication, especially when nanomaterials are functionalized or in water containing NOM. This finding indicates that laboratory workers may be at increased risk of exposure to engineered nanomaterials.
[Chemical, sensory and clinical characterization of lupin marmalades]. (1996)

Legumes are characterized as showing interesting hypoglicemic properties. Their presence in the diet is very useful in controlling the level of blood glucose in diabetic people. Taking in mind this property different formulations of prune marmalades were developed using 5, -7.5, 10 and 15% of full fat sweet lupin flour (FFLF). These samples were submitted to chemical, physical, sensory and clinical analysis. The protein content increased from 0.6 to 5.2% in direct proportion to lupin flour concentration. Energy content remained relatively constant in all formulations. The incorporation of FFLF did not affect the natural dark red prune color and pH, acidity and soluble solids values remained under the limits of Chilean food regulation laws. The samples were analyzed by a Rank preference test. Reported data showed a significative preference for the prune marmalade with 10% HEL (p < 0.05). A facial Hedonic test was used to compare the degree of acceptability between this formula and a control marmalade with fructose as edulcorant. Statistical analysis using the student test did not show significant difference (p < 0.05) between them. The hypoglycemic effect of the lupin flour was tested in seven adult non insulin dependent diabetic patients using the glucose tolerance test. Postprandial blood glucose concentration data was lower in individuals after a test meal of lupin marmalade compared to fructose marmalade. This result would allow diabetic people to eat foods such as marmalades which are known to contain a large amount of carbohydrates.
Diagenetic controlled reservoir quality of South Pars gas field, an integrated approach (2010)

The Dalan-Kangan Permo-Triassic aged carbonates were deposited in the South Pars gas field in the Persian Gulf Basin, offshore Iran. Based on the thin section studies from this field, pore spaces are classified into three groups including depositional, fabric-selective and non-fabric selective. Stable isotope studies confirm the role of diagenesis in reservoir quality development. Integration of various data show that different diagenetic processes developed in two reservoir zones in the Kangan and Dalan formations. While dolomitisation enhanced reservoir properties in the upper K2 and lower K4 units, lower part of K2 and upper part of K4 have experienced more dissolution. Integration of RQI, porosity-permeability values and pore-throat sizes resulted from mercury intrusion tests shows detailed petrophysical behavior in reservoir zones. Though both upper K2 and lower K4 are dolomitised, in upper K2 unit non-fabric selective pores are dominant and fabric destructive dolomitisation is the main cause of high reservoir quality. In comparison, lower K4 has more fabric-selective pores that have been connected by fabric retentive to selective dolomitisation.
Working with Tantalum and Tantalum Alloys (2003)

Abstract Tantalum materials have been used in electronic, chemical processing, and other industries for many years. Solid tantalum shapes are readily produced using conventional ingot metallurgy followed by thermomechanical processing. Alloying tantalum with tungsten improves mechanical strength as well as corrosion resistance without degrading the other physical properties of pure tantalum. Improvements in fabrication and inspection techniques have pushed tantalum fabrications into applications were long term chemical stability and moderate strength are important. Since it is a reactive metal, certain precautions are necessary when fabricating tantalum components. This paper will discuss the processing, design and fabrication, and some failure analyses of tantalum components.
Ogataea neopini sp. nov. and O. corticis sp. nov., with the emendation of the ascomycete yeast genus Ogataea, and transfer of Pichia zsoltii, P. dorogensis, and P. trehaloabstinens to it (2008)

During a survey of yeast strains having high conversion efficiency to ethanol from cellobiose, 'Ogataea pini' ATCC 28781 and 'Pichia pini' NBRC 1794 were found to be distinct from any known species and from each other by a BLAST homology search using the D1/D2 LSU rRNA gene sequences. The D1/D2 phylogeny showed that 'O. pini' ATCC 28781 and 'P. pini' NBRC 1794 belonged to the Ogataea cluster, whereas a comparison of the ITS 1 and 2 regions sequences showed that the ATCC and NBRC strains each formed a species distinct from O. ganodermae, O. pini, O. henricii, and P. zsoltii, based on the D1/D2 sequence divergence. The ATCC and NBRC strains formed two to four hat-shaped ascospores and two to four, or more ones per deliquescent ascus, respectively, were negative for DBB and urease reactions, assimilated methanol slowly and nitrate not at all, and had the major ubiquinone system Q-7. These characteristics coincided basically with the definition of Ogataea proposed by Yamada et al. in 1994, excluding the number of ascospores. On the other hand, the ATCC and NBRC strains differed not only from each other but from relatives in various phenotypic characteristics. These differences suggest that two new yeasts of Ogataea be described as novel. The new species and their type strains are as follows: O. neopini ATCC 28781(T); and O. corticis NBRC 1794(T). In addition, the emendation of the genus Ogataea is made; besides, we propose the transfer of P. zsoltii, P. dorogensis, and P. trehaloabstinens, which were placed in the Ogataea cluster based on the D1/D2 sequence analysis, to the genus Ogataea as O. zsoltii comb. nov., O. dorogensis comb. nov., and O. trehaloabstinens comb. nov.
Inhibition of Mycobacterium tuberculosis dihydrodipicolinate synthase by alpha-ketopimelic acid and its other structural analogues (2016)

The Mycobacterium tuberculosis dihydrodipicolinate synthase (Mtb-dapA) is an essential gene. Mtb-DapA catalyzes the aldol condensation between pyruvate and L-aspartate-beta-semialdehyde (ASA) to yield dihydrodipicolinate. In this work we tested the inhibitory effects of structural analogues of pyruvate on recombinant Mtb-DapA (Mtb-rDapA) using a coupled assay with recombinant dihydrodipicolinate reductase (Mtb-rDapB). Alpha-ketopimelic acid (α-KPA) showed maximum inhibition of 88% and IC50 of 21 μM in the presence of pyruvate (500 μM) and ASA (400 μM). Competition experiments with pyruvate and ASA revealed competition of α-KPA with pyruvate. Liquid chromatography-mass spectrometry (LC-MS) data with multiple reaction monitoring (MRM) showed that the relative abundance peak of final product, 2,3,4,5-tetrahydrodipicolinate, was decreased by 50%. Thermal shift assays showed 1 °C Tm shift of Mtb-rDapA upon binding α-KPA. The 2.4 Å crystal structure of Mtb-rDapA-α-KPA complex showed the interaction of critical residues at the active site with α-KPA. Molecular dynamics simulations over 500 ns of pyruvate docked to Mtb-DapA and of α-KPA-bound Mtb-rDapA revealed formation of hydrogen bonds with pyruvate throughout in contrast to α-KPA. Molecular descriptors analysis showed that ligands with polar surface area of 91.7 Å(2) are likely inhibitors. In summary, α-hydroxypimelic acid and other analogues could be explored further as inhibitors of Mtb-DapA.
FOL Learning for Knowledge Discovery in Documents (2010)

This chapter proposes the application of machine learning techniques, based on first-order logic as a representation language, to the real-world application domain of document processing. First, the tasks and problems involved in document processing are presented, along with the prototypical system DOMINUS and its architecture, whose components are aimed at facing these issues. Then, a closer look is provided for the learning component of the system, and the two sub-systems that are in charge of performing supervised and unsupervised learning as a support to the system performance. Finally, some experiments are reported that assess the quality of the learning performance. This is intended to prove to researchers and practitioners of the field that first-order logic learning can be a viable solution to tackle the domain complexity, and to solve problems such as incremental evolution of the document repository.

Implementation of an Oriented Positioning on a Car-Like Mobile Robot by Fuzzy Control (2006)

In this paper, a fuzzy logic controller (FLC) is used to implement an efficient and accurate positioning of a car-like autonomous mobile robot with a desired orientation. To accomplish such task, which has been called "oriented positioning", two FLCs have been developed: fuzzy robot positioning controller and fuzzy virtual following controller. Computer simulation results illustrate the effectiveness of the proposed technique. Finally, reel-time experiments have been made on an autonomous car-like mobile robot called "Robucar", developed to perform people transportation. Results obtained from these experiments demonstrate the good performance of the controllers
Atrial Reentrant Tachycardia After Surgery for Congenital Heart Disease (2001)

In patients with ART after the surgical correction of congenital heart disease, the use of the noncontact mapping system allows for characterization of the tachycardia and guidance for effective radiofrequency current delivery.
Whole-body cooperative balancing of humanoid robot using COG Jacobian (2003)

Since humanoid robots have a number of degrees-of-freedom in general, a pattern-based approach of the motion control reduces its difficulty. It is necessary, however, to absorb and compensate disturbances in order to maintain the stability of robots in the real world. We developed a balancing method for humanoid robots with a little modification of predesigned motion trajectories. The method proposed has an advantage that it is allowed to choose any combination of joints as modified properties, so that it has enough flexibility, being applicable for various types of robots and motions. It consists of two phases; in the first phase, the referential COG displacement is decided in accordance with both the short-term and the long-term absorption of disturbances. And in the second phase, the COG is manipulated with the whole-body cooperation, using the COG Jacobian. We verified the validity of the method with some simulations.
[Study of rat's p53 gene damage and organ specificity induced by benzidine]. (2006)

The result indicates that benzidine can cause the DNA lesions of exon 7 of p53 gene and its major target organs are liver, bladder and lung. The toxicity mechanism of benzidine is probably related to p53 gene damage.
Tin Whisker Test Method Development (2006)

The International Electronics Manufacturing Initiative (iNEMI) proposed a set of tests that were subsequently standardized by the Joint Electron Device Engineering Council (JEDEC) Solid State Technology Association as JESD22A121. However, further optimization was needed to validate and verify proposed iNEMI tests to determine whether these test methods could differentiate between component surface finishes, to investigate the connection between short-term and long-term tests, and to determine optimal inspection intervals and test durations. In the current work, 15 surface finishes were evaluated using iNEMI's three proposed environmental test conditions. These finishes were evaluated for whisker presence and length using a scanning electron microscope (SEM) every 1000 h or 500 accelerated thermal cycles for a total of at least 9000 h of isothermal testing or 3000 accelerated thermal cycles. Test results showed that thermal cycling and high-temperature/humidity testing could grow whiskers for all Pb-free Sn-based finishes, while only a few finishes exhibited whiskers after 10 000 h in an air-conditioned office environment. The results described in this paper were used to change the JEDEC tin whisker test method from the original iNEMI proposal by decreasing the humidity of the high-temperature humidity test, controlling the ambient test condition to 30 degC and 60% relative humidity (RH), and increasing the number of leads per sample and number of samples (sample size) for inspection
OpenFlow supporting inter-domain virtual machine migration (2011)

Today, Data Center Networks (DCNs) are re-architected in different new architectures in order to alleviate several emergent issues related to server virtualization and new traffic patterns, such as the limitation of bi-section bandwidth and workload migration. However, these new architectures will remain either proprietary or hidden in administrative domains, and interworking protocols will remain in-process of standardization for a time longer than the usually required time to market. Therefore, interworking cloud DCNs to provide the federated clouds is a very challenging issue that seems to be potentially alleviated by a software-defined networking (SDN) approach such as Openflow. In this paper, we propose a network infrastructure as a services (IaaS) software middleware solution based on Openflow in order to abstract the DCN architecture specifities and instantly interconnect DCNs. As a proof of concept we implement an experimental scenario dealing with virtual machine migration. Then, we evaluate the network setup and the migration delay. The use of the IaaS middleware allows automating these operations. OpenFlow solves the problem of interconnecting heterogeneous Data Centers and its implementation offers interesting delay values.
IncFS: An Integrated High-Performance Distributed File System Based on NFS (2006)

Scientific computing applications running in the cluster environment require high performance distributed file system to store and share data. A new approach, the IncFS, of building a high performance distributed file system by integrating many NFS servers is presented in this paper. The IncFS is aimed at providing a simple and convenient way to achieve high aggregate I/O bandwidth for scientific computing applications that require intensive concurrent file access. The IncFS uses a hyper structure to integrate multiple NFS file systems. And it provides multiple data layouts to effectively distribute file data among those NFS servers. Performance evaluations demonstrate that the IncFS has very good data access bandwidth with near perfect scalability, while still maintains an acceptable meta data throughput
Experimental Study on the Adsorption of Water and Ethanol by Cornmeal for Ethanol Dehydration (2006)

A fixed-bed apparatus was designed to investigate the gas adsorption capacity and selectivity of cornmeal for ethanol dehydration. The experiments were performed at near atmospheric pressure and at different temperatures and different ethanol vapor concentrations. Both equilibrium and kinetic adsorptions at the breakthrough point were conducted. The effects of superficial velocity, temperature, and vapor feed concentration on the adsorption capability were studied. The experimental results show that the water selectivity over ethanol on cornmeal is on the order of 0.5−0.6 for both equilibrium and kinetic conditions at the breakthrough point, the equilibrium adsorption capacity for cornmeal is 2.9 g of water/100 g of adsorbent and 2.5 g of ethanol/100 g of adsorbent under the conditions of 91 °C and 93.8 wt % ethanol vapor feed concentration, and the kinetic selectivity of water over ethanol at the breakthrough point is slightly higher than the equilibrium value. The adsorption isotherm for water was correlated as a linear expression for ethanol vapor feed concentrations of 85.0−95.2 wt % The experimental results demonstrate that the likelihood of selective adsorption can be given by the dynamic behavior of the adsorption of water and ethanol on cornmeal.
Analysis of coaxial photonic crystal transmittance by Fourier transform (2005)

In this work, we present an analysis of harmonic frequency transmission filters based on one-dimensional photonic crystals using a Fourier transform approach. This approach relates the photonic crystal transmittance with the Fourier transform of the logarithmic derivate of their refraction index profile. We compare this Fourier approach with the exact transmission calculated by means of the transfer matrix method. We study the accuracy of different functions proposed in the literature that relate the Fourier transform of the index profile with the transmittance. This Fourier approach provides a more intuitive understanding of the transmission properties of one-dimensional photonic crystals. We experimentally demonstrate these properties by using coaxial cables of different impedances. This kind of electrical system is easier to perform experimentally and reproduces, in the radiofrequency range, the properties of one-dimensional photonic crystals.
Immune Mechanisms on Secretory Surfaces (1971)

Immunoglobulins of all five classes are present in external secretions. The predominant one is secretory IgA, a unique form different from serum IgA. Among other differences, secretory IgA contains an interesting glycoprotein, “secretory component.” Secretory IgA antibody apparently is locally produced, but some other immunoglobulins in external secretions seemingly reach the lumina of secretory organs by diffusion. Other known or possible components of mucosal immune mechanisms are cellular immunity, the lysozyme-complement-immunoglobulin system, and interferon.
Matching pursuit and atomic signal models based on recursive filter banks (1999)

The matching pursuit algorithm can be used to derive signal decompositions in terms of the elements of a dictionary of time-frequency atoms. Using a structured overcomplete dictionary yields a signal model that is both parametric and signal adaptive. In this paper, we apply matching pursuit to the derivation of signal expansions based on damped sinusoids. It is shown that expansions in terms of complex damped sinusoids can be efficiently derived using simple recursive filter banks. We discuss a subspace extension of the pursuit algorithm that provides a framework for deriving real-valued expansions of real signals based on such complex atoms. Furthermore, we consider symmetric and asymmetric two-sided atoms constructed from underlying one-sided damped sinusoids. The primary concern is the application of this approach to the modeling of signals with transient behavior such as music; it is shown that time-frequency atoms based on damped sinusoids are more suitable for representing transients than symmetric Gabor atoms. The resulting atomic models are useful for signal coding and analysis modification synthesis.
Mechanical Properties of Square Section Bar Joint by Center Insert Drive Friction Welding Method (2007)

This paper describes the mechanical properties of square section bar welded joint that was made by a center insert drive friction welding method. A center insert drive friction welding method was proposed by authors, which was carried out by the center drive friction welding machine with the center drive gear system. The joint was made up by using a flat disk insert specimen of 10mm or short thickness, and that was inserted to a center gear supported by the drive gears. The material joined was a low carbon steel (same materials) with the weld faying surface shape of 8.9mm square section, and the effect of the friction welding condition on joining phenomena and the joint mechanical properties were investigated. The following conclusions are provided.(1) Friction torque curve had wear and seizure stages until the initial torque, when the base metals were welded at high friction speed and low friction pressure, i.e. 27.5s-1 and 36MPa. On the other hand, when the base metals were welded under high friction speed and high friction pressure conditions, i.e. 27.5s-1 and 90MPa, almost no wear existed until the initial torque was reached. The friction torque rapidly increased and reached the initial peak immediately after the weld faying surfaces contacted each other.(2) The joint that was made by using the disk insert specimen under a friction pressure of 36MPa and a friction time of 1.6s, or a friction pressure of 90MPa and a friction time of 0.6 to 1.5s, had the same tensile strength as the base metal, and fractured in the base metal. Those joints had a notch defect at the corner part in the adjacent region of the welded interfaces although the joints had also 90 degrees bend ductility.(3) When the joint was made by using the disk insert specimen under a friction pressure of 36MPa, a friction time of 1.6s and a forge pressure of 90MPa, it had a notch defect at the corner part in the adjacent region of the welded interfaces. Also, when the joint was made under a friction pressure of 36MPa, a friction time of 1.6s and a forge pressure of 36MPa with by using the convex type insert specimen, it had a notch defect. However, a notch defect of those joints were less in comparison with the joint, it was made under a friction pressure of 36MPa and a friction time of 1.6s with a flat disk insert specimen.(4) The friction welded joint with less notch defect at the corner part in the adjacent region of the welded interfaces was able to make with using a convex type insert specimen and adding forge pressure of 180MPa. The adjacent region of the welded interfaces will be able to make with using a convex type insert specimen and adding higher forge pressure.
Grafting N-vinyl-carbazole on alternating copolymers obtained from dicyclopentadiene (2009)

Copolymers based on dicyclopentadiene and maleic anhydride have been grafted with poly-vinylcarbazole chains using the
ATRP technique. We have found the appropriate conditions for performing the grafting, and the resulting conversions have
been established. All grafted copolymers have been characterized from the structural point of view, as well as by measuring
their improved thermal properties
Unsupervised and transfer learning challenge (2011)

We organized a data mining challenge in “unsupervised and transfer learning” (the UTL challenge), in collaboration with the DARPA Deep Learning program. The goal of this year's challenge was to learn good data representations that can be re-used across tasks by building models that capture regularities of the input space. The representations provided by the participants were evaluated by the organizers on supervised learning “target tasks”, which were unknown to the participants. In a first phase of the challenge, the competitors were given only unlabeled data to learn their data representation. In a second phase of the challenge, the competitors were also provided with a limited amount of labeled data from “source tasks”, distinct from the “target tasks”. We made available large datasets from various application domains: handwriting recognition, image recognition, video processing, text processing, and ecology. The results indicate that learned data representation yield results significantly better than what can be achieved with raw data or data preprocessed with standard normalizations and functional transforms. The UTL challenge is part of the IJCNN 2011 competition program <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> .
