We present Inverse Airborne Optical Sectioning (IAOS), an optical analogy to Synthetic Aperture Radar (ISAR). Moving targets, such as walking people, that are heavily occluded by vegetation can be made visible and tracked with a stationary sensor (e.g., hovering camera drone above forest). introduce the principles of IAOS (i.e., inverse synthetic aperture imaging), explain how signal occluders ...

About two years ago our laboratory received for identification a sparganum of Spirometra sp. (about 10 cm long) removed from a nodule in the knee of a Tanzanian negro by Doctor Knut Saug. About the same time we received for identification two tetrathyridia of Mesocestoides sp. (about 8 cm long) found in the peritoneum of a Norwegian cat. The latter was the first record of tetrathyridia found in...

BACKGROUND The minimally invasive lateral interbody fusion (MIS LIF) in the lumbar spine can correct coronal Cobb angles, but the effect on sagittal plane correction is unclear. METHODS A retrospective review of thirty-five patients with lumbar degenerative disease who underwent MIS LIF without supplemental posterior instrumentation was undertaken to study the radiographic effect on the resto...

Student sectioning is the problem of assigning students to particular sections of courses they request while respecting constraints such as course structures, section limits, and reserved spaces. Students may also provide preferences on class times and course alternatives. In this paper, three approaches to this problem are examined and combined in order to tackle it on a practical level: stude...

BACKGROUND There is a paucity of information on structural organization of muscular bundles in the interatrial septum (IAS). The aim was to investigate histologic and ultrastructural organization of muscular bundles in human IAS, including fossa ovalis (FO) and flap valve. METHODS Macroscopic and light microscopy evaluations of IAS were performed from postmortem studies of 40 patients. Twenty...

Today, the ready availability of finer instruments, suture material, and operating microscopes has provided the stimulus to further refinements in ophthalmic and other microsurgical techniques, where, only a decade ago, with adequate operative results from old techniques, interest could not be sustained in new ideas or inventions. The present paper describes the general features of a new vibrat...

The effects on spontaneous ovulation associated with the unilateral or bilateral sectioning of the superior ovarian nerves (SON) were analyzed in guinea pigs at different time intervals of the estrous cycle. Day 1 of the estrous cycle was defined as the day when the animal presents complete loss of the vaginal membrane (open vagina). Subsequent phases of the cycle were determined by counting th...
