Abstract:

The invention provides compounds of formula (I), wherein R represents C alkoxy optionally substituted by one or more fluorine atoms; R represents H or C alkoxy optionally substituted by one or more fluorine atoms; R represents one or more groups independently selected from H, halogen, C alkoxy and CF ; in addition, R and one R group may together represent âOCH â, the methylene group being attached to the ortho-position of the pendant phenyl ring; R represents a 4-, 5- or 6-membered heterocyclic ring containing 1 or 2 heteroatoms selected from N, O and S, the ring being optionally fused to a benzene ring or a 5- or 6-membered heterocyclic ring containing 1 or 2 heteroatoms selected from N, O and S, the ring system as a whole being optionally substituted; X represents CH or N; and L is absent or represents a cyclic group or an open chain group; and the pharmaceutically acceptable salts thereof. The compounds of formula (I) are useful in the treatment of inter alia benign prostatic hyperplasia.

Appl. No.:

10/710281

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G11C 11/00

US Classification:

365158, 171173

Abstract:

A method for determining a desired anisotropy axis angle for a magnetic random access memory (MRAM) device includes selecting a plurality of initial values for the anisotropy axis angle and determining, for each selected initial value, a minimum thickness for at least one ferromagnetic layer of the MRAM device. The minimum thickness corresponds to a predefined activation energy of an individual cell within the MRAM device. For each selected value, a minimum applied magnetic field value in a wordline direction and a bitline direction of the MRAM device is also determined so as maintain the predefined activation energy. For each selected value, an applied power per bit value is calculated, wherein the desired anisotropy axis angle is the selected anisotropy axis angle corresponding to a minimum power per bit value.

US Classification:

726 7

Abstract:

Systems and methods for verifying a user based on reputational information are provided. In particular, a computerized CAPTCHA system consisting of one or more computers can determine a trust score based on one or more reputation signals associated with a user computing device, select a challenge to provide to the user computing device based on the trust score, and determine whether to verify the user computing device based on a received response to the challenge and/or the trust score.

International Classification:

G10L 17/24

US Classification:

381 17

Abstract:

Systems and methods for generating and performing a three-dimensional audio CAPTCHA are provided. One exemplary system can include a decoy signal database storing a plurality of decoy signals. The system also can include a three-dimensional audio simulation engine for simulating the sounding of a target signal and at least one decoy signal in an acoustic environment and outputting a stereophonic audio signal based on the simulation. One exemplary method includes providing an audio prompt to a resource requesting entity. The audio prompt can have been generated based on a three-dimensional audio simulation of the sounding of a target signal containing an authentication key and at least one decoy signal in an acoustic environment. The method can include receiving a response to the audio prompt from the resource requesting entity and comparing the response to the authentication key.

US Classification:

257506, 438 3, 257E43006, 257E43001

Abstract:

Novel methods for reliably and reproducibly forming magnetic tunnel junctions in integrated circuits are described. In accordance with aspects of the invention, sidewall spacer features are utilized during the processing of the film stack. Advantageously, these sidewall spacer features create a tapered masking feature which helps to avoid byproduct redeposition during the etching of the MTJ film stack, thereby improving process yield. Moreover, the sidewall spacer features may be used as encapsulating layers during subsequent processing steps and as vertical contacts to higher levels of metallization.
