simultaneous chiral resolution of monosaccharides as 8 aminonaphthalene 1 3 6 trisulfonate derivatives by ligand Exchange ce using borate as a central ion of the chiral selector
Electrophoresis, 2007Co-Authors: Shuji Kodama, Senichi Aizawa, Tomohisa Yamashita, Tomoko Kemmei, Atsushi Taga, Atsushi Yamamoto, Kazuichi HayakawaAbstract:: Six reducing monosaccharides (mannose, galactose, fucose, glucose, xylose, and arabinose) were derivatized with 8-aminonaphthalene-1,3,6-trisulfonate (ANTS). Based on the chiral ligand-Exchange Principle using borate as a central ion of the chiral selector and (S)-3-amino-1,2-propanediol (SAP) as a chiral selector ligand, all of the six ANTS-monosaccharides were simultaneously enantioseparated using absorbance at 245 nm for detection. The optimum conditions for both high resolution and moderately short migration time consisted of 200 mM SAP-200 mM borate buffer (pH 9.2) containing 10% ACN as a BGE at 30 degrees C with an applied voltage of +30 kV. It was revealed that the proposed chiral ligand-Exchange CE using the SAP-borate system was applicable to enantioseparation of not only diols but also polyols.

A new micro-tools Exchange Principle for micromanipulation
2004 IEEE RSJ International Conference on Intelligent Robots and Systems (IROS) (IEEE Cat. No.04CH37566), 2004Co-Authors: Cédric Clévy, A Hube, N. ChailleAbstract:This paper deals with the design, fabrication and characterization of a new micro-tools changer for a micromanipulation station including three translation stages (X-Y-Z manipulator) and a new piezoelectric microgripper. This system can be implemented in confined workspaces such as a scanning electron microscope (SEM) or more generally in a micro-factory station by the reduction of the manipulator's size and the flexibility gain. The Principle of this micro-tools changer is based on the use of a thermal glue whose state (liquid or solid) is controlled by surface mounted device (SMD) electrical resistances. Such system allows hundreds of automatic micro-tools Exchanges with a maximum position error between two consecutive tools Exchanges of respectively 4.2, 2.8 and 5.4 /spl mu/m on the X, Y and Z axis. To validate the use of the micromanipulation station in a SEM, an experimental comparison of the working Principle in low (vacuum) and high (air) pressure has also been established through thermal and degassing studies.

On some properties of threshold generated implications
Fuzzy Sets and Systems, 2012Co-Authors: Sebastia Massanet, Joan TorrensAbstract:In this paper, the recently introduced construction method of a fuzzy implication from two given ones, called threshold generation method, is studied. This method preserves several of the most usual properties of fuzzy implications from the initial ones to the threshold generated implication. In particular, the preservation of the Exchange Principle, the law of importation and the distributivities with t-norms and t-conorms, stating the minimal necessary conditions to ensure this fact is studied. From these results, some properties of h-implications, as a particular case of threshold generated implications, are pointed out.

On a new class of fuzzy implications: h-Implications and generalizations
Information Sciences, 2011Co-Authors: Sebastia Massanet, Joan TorrensAbstract:A new class of fuzzy implications called the h-implications is introduced. They are implications generated from an additive generator of a representable uninorm in a similar way of Yager's f- and g-implications which are generated from additive generators of continuous Archimedean t-norms and t-conorms. Basic properties of these implications are studied in detail. Modifications and generalizations of the initial definition are presented and their properties studied and compared between them. One of the modifications, called (h,e)-implications, is another example of a fuzzy implication satisfying the Exchange Principle but not the law of importation for any t-norm, in fact for any function F : [0,1]^2->[0,1].

FOCI - Implications generated from additive generators of representable uninorms: (h, e)-implications
2011 IEEE Symposium on Foundations of Computational Intelligence (FOCI), 2011Co-Authors: Sebastia Massanet, Joan TorrensAbstract:A new class of fuzzy implications called (h, e)-implications is introduced. They are implications generated from an additive generator of a representable uninorm in a similar way of Yager's f- and g-implications which are generated from additive generators of continuous Archimedean t-norms and t-conorms, respectively. In addition, they satisfy a classical property of some types of implications derived from uninorms that is I(e, y) = y for all y ∈ [0, 1] and they are another example of a fuzzy implication satisfying the Exchange Principle but not the law of importation for any t-norm, in fact for any function F : [0, 1]2 → [0, 1]. Other properties of these implications are studied in detail such as other classical tautologies: contrapositive symmetry and distributivity. Finally, it is proved that they do not intersect with any of the most used classes of implications.

The law of importation versus the Exchange Principle on fuzzy implications
Fuzzy Sets and Systems, 2011Co-Authors: Sebastia Massanet, Joan TorrensAbstract:Some open problems on fuzzy implications dealing with the so-called importation law are studied and totally or partially solved in this work. A weaker version of the law of importation, called the weak law of importation, is introduced. The relationships of these two properties and the Exchange Principle are studied. In particular, it is proved that the law of importation is stronger than the Exchange Principle. On the other hand, the three properties are equivalent for some kind of fuzzy implications, those that satisfy a boundary property. Along this study, new characterizations of (S,N)-implications, R-implications and their counterparts for uninorms based on the weak law of importation are showed.

IFSA/EUSFLAT Conf. - Fuzzy Implications and the Weak Law of Importation
2009Co-Authors: Sebastia Massanet, Joan TorrensAbstract:Some open problems on fuzzy implications dealing with the so-called importation law are studied and totally or partially solved in this work. In particular, it is proved that such property (in fact a weaker version than the law of importation) is stronger than the Exchange Principle. Along this study, new characterizations of (S, N)-implications and R-implications involving the law of impor- tation are showed. Keywords— Implication function, Exchange Principle, law of im- portation, (S, N)-implication, R-implication.
