Punctate inner choroidopathy (PIC) is a rare idiopathic inflammatory disorder of the retina and choroid usually affecting healthy, young, myopic females and presenting with photopsia, paracentral scotomata, and blurred vision. It is characterized by yellow-white chorioretinal lesions concentrated in the posterior pole, no vitritis, relapsing inflammatory activity of the retina and choroid, and ...

This report is a sequel to an earlier report [Fuller, 19711 that develops a minimal-total-processing-time (MTPT) drum scheduling algorithm. A quantative comparison between MTPT schedules and shortest-latency-timefirst (SLTF) schedules, commonly acknowledged as good schedules for drumlike storage units, is presented here. The analysis develops an analogy to random walks and proves several asympt...

Stereo vision is the recovery of depth of a scene using multiple images with di erent points of view. The major task in stereo vision is establishing correspondence of points between images given a known pinhole-model of the stereo cameras. Two major approaches to matching points have been used widely: feature-based matching and areaor correlationbased matching. It is well known that both appro...

We treat the problem of edge detection as one of statistical inference. Local edge cues, implemented by lters, provide information about the likely positions of edges which can be used as input to higher-level models. Diierent edge cues can be evaluated by the statistical eeectiveness of their corresponding lters evaluated on a dataset of 100 pre-segmented images. We use information theoretic m...

Comparison of pentane extraction and steam distillation of intact leaves of Lippia dulcis (hierbia dulce, ex Mexico) yielded 2.13% (DW basis) vs. 0.13% for pentane extraction (18 h, shaking). Analyses of the oils showed (pentane; distilled): camphor (33.9, 21.2%), camphene (1.8, 12.7%), 6-methyl-5hepten-2-one (7.9, 3.4%), (+)-hernandulcin, the sweet sesquiterpene (9.2, 5.9%), 3-methyl-2cyclohex...

Auditory neurons can be characterized by a spectro-temporal receptive field, the kernel of a linear filter model describing the neuronal response to a stimulus. With a view to better understanding the tuning properties of these cells, the receptive fields of neurons in the zebra finch auditory fore-brain are compared to a set of artificial kernels generated under the assumption of sparseness; t...

et al,' in which the authors demonstrated an altered character in the small bowel's bacterial flora in patients with rheumatoid arthritis. However, the authors did not demonstrate the presence of bacterial overgrowth. The syndrome of bacterial overgrowth is characterised by diarrhoea with malabsorption. The mechanism by which the bacterial overgrowth causes symptoms is not known. These symptoms...
