Abstract: The present invention discloses an apparatus and a method of modulating a carrier with digital information having a series of datums represented in a plurality of symbols, the method comprising selecting a first number of half-periods of a first phase distinguished carrier signal for representing a corresponding symbol of a first one of the datums, selecting a second number of half-periods of a second phase distinguished carrier signal for representing a corresponding symbol of the datum following the first datum, determining at least one matching carrier signal having a third number of half-periods of a format to conform to a transition of the first phase distinguished carrier signal to the second phase distinguished carrier signal, and sequentially arranging the first number of half-periods of the first phase distinguished carrier signal, the third number of half-periods of the matching carrier signal and the second number of half-periods of the second phase distinguished carrier signal.

Abstract: Compounds of the structure I: are useful for treating bacterial growth, wherein E is selected from the group consisting of B, P, and S, T1 and T2 are each independently selected from the group consisting of O, NR, and CH2, where R=H or C1-C8 alkyl, or C1-C8 oxoalkyl, and L is selected from the group consisting of ethylene, propylene, and four to six-membered alicyclic and aromatic rings, provided that structure I does not include AI-2-borate. The compounds may be used to treat bacterial infections in human beings and to regulate biofilm formation. Pharmaceutical compositions comprising one or more such compounds are useful for treating bacterial infections in human beings.

Abstract: An integrated optoelectronic silicon biosensor that can detect biomolecules by the change of the optical coupling between the integrated light source and the integrated detector that is caused by the binding of the appropriately labeled analytes onto the recognition molecules, that have been previously immobilized onto the integrated optical fiber that connects the optical source with the detector. The device contains the optoelectronic silicon chip and its biological activation. The optoelectronic chip is realized following integrated circuits fabrication methods so as the light source, the detector and the optical fiber, that optically couples the light source with the detector, to be monolithically integrated on the same silicon substrate. The biological activation of the chip is performed through physicochemical modification of the chip surface in order to permit immobilization of the recognition biomolecules onto the optical fiber surface.

Abstract: A vessel hull transducer modular mounting system enables transducers to be replaced and upgraded without necessitating the further modification of the hull and thus not necessitating the dry-docking of the vessel. A further feature includes the ability to reduce and dampen acoustic shock impact on the transducer. Another feature includes the ability to extend and retract the transducer which can operate in bottom scan, forward looking, side scan, searchlight, and sweep modes.

Abstract: There are disclosed a novel microorganism Serratia marcescens strain and a prodigiosin isolated from the microorganism. The prodigiosin is useful as an immunosuppressive in various fields, including the treatment of the diseases requiring immunosuppression and the basic research for the diseases, the transplantation of the organs or tissues, and the immune cells.

Abstract: In a shell-and-tube type reactor, the leakage between the upper and lower chambers is substantially decreased by tightly fitting the reaction tubes to the shield. The present invention provides a reactor for use in catalytic gas phase oxidation characterized by expanding reaction tubes to at least one groove formed in the reaction tube-fixing part of an intermediate tube sheet to form a shield, thereby forming plural of chambers with the intermediate tube sheet, and forming an expansion joint around the periphery of each of the chambers.
