BACKGROUND Myomectomy often causes adhesion formation and decreases subsequent fertility. The purpose of the present study was to evaluate the effectiveness of several antiadhesion barrier materials in preventing adhesion after myomectomy. METHODS We prospectively classified 63 women undergoing myomectomy alone into four groups according to the type of(More)
Previous work in simultaneous localisation and mapbuilding (SLAM) for mobile robots has focused on the simplified case in which a robot is considered to move in two dimensions on a ground plane. While this is sometimes a good approximation, a large number of real-world applications require robots to move around terrain which has significant slopes and(More)
A novel active stereo vision system with a pair of foveated wide angle lenses is presented. The projection curve of the lens is designed so that it facilitates active vision algorithms for motion analysis, object identi cation, and precise xation. A pair of such lenses are mounted on a specially designed active stereo vision platform. It is compact and(More)
In this paper, we propose a deformable-model-driven method to recognize the state of hanging clothes using three-dimensional (3D) observed data. For the task to pick up a specific part of the clothes, it is indispensable to obtain the 3D position and posture of the part. In order to robustly obtain such information from 3D observed data of the clothes, we(More)
This paper presents some advanced examples of reactive vision-based cooperative behaviors: (1) Chasing and posing against another robot among others, (2) Unblocking the path of another robot by removing an obstacle, (3) Passing an object from one to another. These behaviors are demonstrated using real mobile robots equipped with CCD cameras, in a complex(More)
We report a patient with diffuse uterine leiomyomatosis, who wished to become pregnant. We performed hysteroscopic myomectomy after treatment with nafarelin acetate for 6 months. The patient conceived spontaneously soon after hysteroscopic myomectomy, and delivered a 2,798-g healthy baby.
Endometriosis is defined as the existence of endometrial tissue outside the uterine cavity, and it includes a chronic, inflammatory reaction associated with female infertility and pelvic pain. Endometriosis occurs in 7 to 10% of women. Although it has been studied for more than 50 years, the pathogenesis and development of endometriosis are still poorly(More)
PATIENT Male, 83 FINAL DIAGNOSIS: Membranous glomerulonephritis Symptoms: Producting cough Medication: - Clinical Procedure: - Specialty: Nephrology. OBJECTIVE Rare disease. BACKGROUND Membranous glomerulonephritis can occur secondarily from infectious diseases. There are no reports describing membranous glomerulonephritis caused by non-tuberculous(More)
In this paper, we present a novel design and implementation of a foveated wide angle lens. It is strongly motivated towards applications for active vision in complex and dynamic environments. The projection curve is designed so that it facilitates active vision algorithms for motion analysis, object identi cation, and precise xation. The implementation(More)
A novel framework for multiple robot cooperation called \Cooperation by Observation" is presented. It introduces many interesting issues such as viewpoint constraint and role interchange, as well as novel concepts like \attentional structure". The framework has the potential to realize a high level of task coordination by decentralized autonomous robots(More)
