The aim of this study was to evaluate in breast cancer whether subdermal (SB) re-injection improves surgical detection (SD) of the sentinel node (SN) in patients with negative lymphoscintigraphy on peritumoral (PT) injection, without increasing the false-negative (FN) rate. Group I comprised 261 patients with invasive breast cancer >3 cm and clinically(More)
BACKGROUND/AIMS The use of drainage after liver resection remains controversial. Data of the usefulness of drains in cirrhotic patients undergoing surgical resection are scarce. The objective of our study is to assess the usefulness of intra-abdominal drainage after liver resection for hepatocellular carcinoma in cirrhotic patients. METHODOLOGY We(More)
OBJECTIVE The aim of the study was to evaluate the efficacy of lymphatic mapping and sentinel node biopsy in non-palpable breast cancer (NPBC) patients in comparison with palpable breast cancer (PBC) patients. MATERIAL AND METHODS 199 breast cancer patients were studied. Patients were classified into two groups: NPBC and PBC. Following sentinel node(More)
This work introduces a method and apparatus for measuring real mobile robot cleaning performances based on a dedicated vision system. The measurement method can be applied to any kind of floor cleaning mobile robot but in this work it has been applied to a proprietary design. The paper presents the analysis of the first results obtained and ends with the(More)
This work proposes the creation of a bioinspired electronic white cane for blind people using the whiskers principle for short-range navigation and exploration. Whiskers are coarse hairs of an animal's face that tells the animal that it has touched something using the nerves of the skin. In this work the raw data acquired from a low-size terrestrial LIDAR(More)
Estimation of grapevine vigour using mobile proximal sensors can provide an indirect method for determining grape yield and quality. Of the various indexes related to the characteristics of grapevine foliage, the leaf area index (LAI) is probably the most widely used in viticulture. To assess the feasibility of using light detection and ranging (LiDAR)(More)
This paper describes a measurement system designed to register the displacement of the legs using a two-dimensional laser range sensor with a scanning plane parallel to the ground and extract gait parameters. In the proposed methodology, the position of the legs is estimated by fitting two circles with the laser points that define their contour and the gait(More)
