摘要:
The present invention provides methods to detect degenerative processes and abnormalities in soft tissues at high spatial resolution, high signal-to-noise ratio and short scanning times, based on quantitative tissue properties. These methods might provide a useful tool to detect and assess abnormalities in soft tissues and to monitor disease progression.

摘要:
Ranges and transverse coordinates of point light sources are estimated by forming an out-of-focus image of the point light sources using a camera. The out-of-focus image is formed such that it is imaged as a disk or ring having a bright periphery. This is conveniently achieved by taking advantage of under- or overcorrected spherical aberration in the lens, or of diffraction effects caused by the interaction of light with the aperture of the lens. Range estimates can be calculated from a size metric of the disk or ring, which in turn can be accurately determined due to its bright periphery. Range estimates can also be obtained using certain pattern matching methods.

Ranges of objects are determined using a camera equipped with a rotating optical axis displacement unit (ODU). The ODU receives light about an offset line of sight, and displaces it to a substantially parallel camera line of sight. The displaced light is focussed onto an image sensor. Images of a scene are captures as the ODU rotates. Range information is calculated from the apparent motion of objects in the captured images.

A meeting effectiveness indicator provides information to participants of a meeting. The information includes messages that the meeting has gone off topic, and resources are being wasted. Participants within a room or local vicinity of the indicator used wired or wireless transmitters to send indications that the meeting is going off topic. Remote participants linked to a network also send indications via a network interface. Once a total number of indications reaches a warning threshold, the indicator warns the participants that the meeting is going off topic with a warning message. If additional indications are received, then the total number of indications will reach a tangent threshold, and the participants are alerted using a tangent message that the meeting is off topic.

Compounds of Formula I: ##STR1## wherein: X.sub.1, and X.sub.2 are each independently either O.sup.- or S.sup.- ;X.sub.3 and X.sub.4 are each independently either --H or --OH, with the proviso that X.sub.3 and X.sub.4 are not simultaneously --H;R.sub.1 is selected from the group consisting of O, imido, methylene and dihalomethylene;R.sub.2 is selected from the group consisting of H, halo, alkyl, substituted alkyl, alkoxyl, nitro and azido;R.sub.3 is selected from the group consisting of H, alkyl, acyl, aryl, and arylalkyl; andR.sub.4 is selected from the group consisting of --OR', --SR', --NR', and --NR'R", wherein R' and R" are independently selected from the group consisting of H, alkyl, substituted alkyl, aryl, substituted aryl, arylalkyl, alkoxyl, and aryloxyl, with the proviso that R' is absent when R.sub.4 is double bonded from an oxygen or sulfur atom to the carbon at the 4-position of the pyrimidine ring, are used in methods of hydrating lung mucus secretions and treating lung disorders such as cystic fibrosis, ventilator-associated pneumonia, chronic bronchitis, chronic obstructive pulmonary disorder and primary ciliary dyskinesia. Pharmaceutical compositions containing compounds of Formula I, and novel compounds of Formula I are also described.
