BACKGROUND AND OBJECTIVES Only few randomized trials or comparative studies with large number of patients have been reported on the outcomes of thoracoscopic and laparoscopic esophagectomy (TLE) with cervical anastomosis and open 3-field esophagectomy (OE) for patients with esophageal cancer. The objective of this study is to compare the safety,(More)
Despite the successes in capturing continuous distributions, the application of generative adversarial networks (GANs) to discrete settings, like natural language tasks, is rather restricted. The fundamental reason is the difficulty of backpropagation through discrete random variables combined with the inherent instability of the GAN training objective. To(More)
The evolution of a dynamic walking gait of biped robot is presented in this paper. The gait is generated for a biped robot to walk on flat ground and climb up stairs. For the trajectory based gait generation, various parameters satisfy ZMP criterion and can realize continuous walking. The evolutionary algorithm is used to choose the parameter combinations.(More)
Double-lumen endotracheal tube (DLET) anaesthesia is the commonly used method in minimally invasive oesophagectomy (MIE). However, DLET intubation does have its disadvantages. Firstly, the placement of the DLET needs a skilled anaesthetist with familiarity of the technique and subsequent ability to perform a fibre-optic bronchoscopy for confirmation.(More)
This paper describes an integrated quasi‐ autonomous four‐limbed robot, named Capuchin, which is equipped with appropriate sensing, planning and control capabilities to “free‐climb” vertical terrain. Unlike aid climbing that takes advantage of special tools and/or engineered terrain features, free climbing only relies on friction at the(More)
Abstract–This paper presents the research work on a small size humanoid robot: RoboSapien. The objective of this project is to build a platform for the study of dynamic walking and the artificial intelligence tools. In all, the robot has 17 degrees of freedom and each joint is driven by a DC servo motor. Two DSPs are utilized in the control system. In this(More)
The effect of neoadjuvant chemotherapy on the survival of patients with thoracic esophageal squamous cell carcinomas (ESCCs) remains controversial. The optimal management strategy for resectable ESCCs varies regionally based on local randomized controlled trials. A systematic review and meta-analysis was conducted to re-evaluate this controversial issue.A(More)
BACKGROUND The objective of this study was to describe a cosmetic skin incision for resection of large anterior mediastinal masses, and to review our experience with this technique. METHODS From 1999 to 2010, 55 patients with a diagnosis of large anterior mediastinal masses underwent "goblet"-shaped skin incision with midline sternotomy. The(More)
