#1
Peiwu Yu, Yingxue Hao
There are vast land and lots of people in western China, but the economy developing is relatively slow. However, the minimally invasive surgery was carried out firstly in China. Moreover, the type, number and difficulty of the minimally invasive surgery increased year by year. Especially, in the western area of China, Dr Zhou Zongguang, Yu Peiwu and Zheng Shuguo et al. have performed much pioneering work in laparoscopic surgery for rectal cancer, gastric cancer and laparoscopic liver resection. They led the standard development of minimally invasive in China...

In nature, insects show impressive adaptation and learning capabilities. The proposed computational model takes inspiration from specific structures of the insect brain: after proposing key hypotheses on the direct involvement of the mushroom bodies (MBs) and on their neural organization, we developed a new architecture for motor learning to be applied in insect-like walking robots. The proposed model is a nonlinear control system based on spiking neurons. MBs are modeled as a nonlinear recurrent spiking neural network (SNN) with novel characteristics, able to memorize time evolutions of key parameters of the neural motor controller, so that existing motor primitives can be improved...

Biological motion-sensitive neural circuits are quite adept in perceiving the relative motion of a relevant stimulus. Motion perception is a fundamental ability in neural sensory processing and crucial in target tracking tasks. Tracking a stimulus entails the ability to perceive its motion, i.e., extracting information about its direction and velocity. Here we focus on auditory motion perception of sound stimuli, which is poorly understood as compared to its visual counterpart. In earlier work we have developed a bio-inspired neural learning mechanism for acoustic motion perception...

Robotic surgery represents a new horizon in minimally-invasive urological surgery. This systematic review of the literature and meta-analysis examines the effectiveness of robotic surgery compared with laparoscopic or open surgery for major uro-oncological procedures. 25 articles reported findings from 8 trials of prostatectomy (4 trials) and cystectomy (4 trials) including 1033 participants. Robotic surgery is comparable to laparoscopic or open surgery for oncological outcomes, overall complications, and provides somewhat better functional outcome, when compared to laparoscopic and open surgery...

The Robot Operating System (ROS) provides roboticists with a standardized and distributed framework for real-time communication between robotic systems using a microkernel environment. This paper looks at how ROS metadata, Unified Robot Description Format (URDF), Semantic Robot Description Format (SRDF), and its message description language, can be used to identify key robot characteristics to inform User Interface (UI) design for the teleoperation of heterogeneous robot teams. Logical relationships between UI components and robot characteristics are defined by a set of relationship rules created using relevant and available information including developer expertise and ROS metadata...

Implantable sensor systems are effective tools for biomedical diagnosis, visualization and treatment of various health conditions, attracting the interest of researchers, as well as healthcare practitioners. These systems efficiently and conveniently provide essential data of the body part being diagnosed, such as gastrointestinal (temperature, pH, pressure) parameter values, blood glucose and pressure levels and electrocardiogram data. Such data are first transmitted from the implantable sensor units to an external receiver node or network and then to a central monitoring and control (computer) unit for analysis, diagnosis and/or treatment...

Triboelectric nanogenerators (TENGs) can be applied for the next generation of artificial intelligent products, where skin-like tactile sensing advances the ability of robotics to feel and interpret environment. In this paper, a flexible and thin tactile sensor was developed on the basis of dual-mode TENGs. The effective transduction of touch and pressure stimulus into independent and interpretable electrical signals permits the instantaneous sensing of location and pressure with a plane resolution of 2 mm, a high-pressure-sensing sensitivity up to 28 mV·N(-1), and a linear pressure detection ranging from 40 to 140 N...

Spiral capsule robots can be applied to human gastrointestinal tracts and blood vessels. Because of significant variations in the sizes of the inner diameters of the intestines as well as blood vessels, this research has been unable to meet the requirements for medical applications. By applying the fluid dynamic equations, using the computational fluid dynamics method, to a robot axial length ranging from 10(-5) to 10(-2) m, the operational performance indicators (axial driving force, load torque, and maximum fluid pressure on the pipe wall) of the spiral capsule robot and the fluid turbulent intensity around the robot spiral surfaces was numerically calculated in a straight rigid pipe filled with fluid...

BACKGROUND: Bilateral axillo-breast approach robotic thyroidectomy (BABA RT) is frequently performed and has excellent cosmetic results. However, there has been concern that subcutaneous tunneling in construction of the operation field might interfere with subsequent breast imaging. In this study, we evaluated whether BABA RT interferes with breast imaging by evaluating serial perioperative results of mammography and ultrasonography. METHODS: We selected female patients who underwent BABA RT between 2008 and 2012, and who also had mammography or ultrasonography pre- and postoperatively, and compared the results of pre- and postoperative imaging...

Visual 3D reconstruction techniques provide rich ecological and habitat structural information from underwater imagery. However, an unaided swimmer or diver struggles to navigate precisely over larger extents with consistent image overlap needed for visual reconstruction. While underwater robots have demonstrated systematic coverage of areas much larger than the footprint of a single image, access to suitable robotic systems is limited and requires specialized operators. Furthermore, robots are poor at navigating hydrodynamic habitats such as shallow coral reefs...

H Hess, Jennifer L Ross
Biological systems have evolved to harness non-equilibrium processes from the molecular to the macro scale. It is currently a grand challenge of chemistry, materials science, and engineering to understand and mimic biological systems that have the ability to autonomously sense stimuli, process these inputs, and respond by performing mechanical work. New chemical systems are responding to the challenge and form the basis for future responsive, adaptive, and active materials. In this article, we describe a particular biochemical-biomechanical network based on the microtubule cytoskeletal filament - itself a non-equilibrium chemical system...

Various endoscopic suturing and tying methods have been reported, but these methods remain imperfect because knots are sometimes not tied completely and additional stitches are needed. To address this problem, we developed the "Figure 4" technique in which the knot can be easily slid to the suture point and tied by pulling suture tail-these knots will never come untied. This technique requires very simple technique and can be used in other surgical procedures such as conventional laparoscopic surgery.

In the indoor environment, variation of the magnetic field is caused by building structures, and magnetic field map navigation is based on this feature. In order to estimate position using this navigation, a three-axis magnetic field must be measured at every point to build a magnetic field map. After the magnetic field map is obtained, the position of the mobile robot can be estimated with a likelihood function whereby the measured magnetic field data and the magnetic field map are used. However, if only magnetic field map navigation is used, the estimated position can have large errors...
