摘要:
The present invention is concerned with isoxazole-thiazole derivatives of formula I, having affinity and selectivity for GABA A α5 receptor, their manufacture, pharmaceutical compositions containing them and their use as therapeutically active substances. The active compounds of the present invention are useful as cognitive enhancer or for the therapeutic and/or prophylactic treatment of cognitive disorders like Alzheimer's disease.
摘要:
A multiple mode digitization system for a non-destructive inspection instrument which makes use of a multiplexing circuit and a single set of analog to digital converters to efficiently digitize analog test signals from a plurality of inputs. In the preferred embodiment, each of the analog to digital converters in the system is driven with an independent and separate clock signal, allowing for propagation delay compensation among the plurality of test signals as well as interleaved sampling such that custom sampling rates can be used for each input without the need for more than one clock frequency. In an alternate embodiment, phase adjustments on the sampling clocks are used only for interleave sampling, and digital filters are used to provide signal propagation delay compensation.
摘要:
The invention relates to isoxazolo-pyrazine derivatives and their pharmaceutically acceptable salts having affinity and selectivity for the GABA A α5 receptor binding site, their manufacture, and pharmaceutical compositions containing them. The compounds of present invention are inverse agonists of GABA A α5. The invention also relates to methods for enhancing cognition and for treating cognitive disorders like Alzheimer's disease.
摘要:
The present invention is concerned with aryl-isoxazol-4-yl-imidazo[1,2-a]pyridine derivatives of formula I: wherein R1 to R5 are as defined in the specification and pharmaceutically acceptable acid addition salts thereof. This class of compounds has high affinity and selectivity for GABA A α5 receptor binding sites and might be useful as cognitive enhancer or for the treatment of cognitive disorders like Alzheimer's disease.
摘要:
A system and method for managing the delivery of goods. The system and method particularly provides for manifesting and controlling route-based delivery of orders or packages from a vendor to one or more locations accessible by customers. The locations may include automated, self-service vending machines and/or will-call lockers, under the control of a system (ideally centralized and automated) that can receive and actively manage manifest information.
摘要:
The present invention is concerned with aryl-isoxazol-4-yl-imidazo[1,5-a]pyridine derivatives of formula wherein: R1, R2, and R3 are as defined herein and pharmaceutically acceptable acid addition salts thereof. These compounds have high affinity and selectivity for GABA A α5 receptor binding sites. The invention also relates to methods for enhancing cognition and treating cognitive disorders like Alzheimer's disease.
摘要:
The present invention is concerned with 3-aryl-isoxazole-4-carbonyl-benzofuran derivatives of formula I wherein R1, R2, and R3 are as defined in the specification and claims and with their pharmaceutically acceptable acid addition salts. These compounds have a high affinity and selectivity for GABA A α5 receptor binding sites and might be useful as cognitive enhancer or for the treatment of cognitive disorders like Alzheimer's disease.
摘要:
An axial flow rotary valve (1) for an internal combustion engine and method of manufacture thereof. The valve comprising a centre portion (5) having a cylindrical periphery, inlet and exhaust portions (9, 16) both smaller in diameter than the centre portion, and an inlet port (3) and an exhaust port (4) terminating respectively as an inlet opening (6) and an exhaust opening (7) in the periphery of the centre portion. The centre portion having at least one elongate passage (21) communicating between the inlet portion and the exhaust portion, the whole of the passage being disposed circumferentially outside the openings and radially outside at least one of the inlet and exhaust portions.
