Minimally invasive surgery is the gold standard treatment for deep endometriosis when medical management fails. In selected cases, such as when bowel or urinary tract are involved, robotic assisted ...surgery can be useful due to its characteristics of high dexterity and manoeuvrability. This is the first case of robotic en-bloc excision of posterior compartment deep endometriosis performed with the new HugoTM RAS system.
The purpose of this video article is to show for the first time the feasibility of bowel surgery for deep endometriosis with this new robotic device.
A 24-years-old woman affected by severe dysmenorrhea, chronic pelvic pain, dyschezia and dyspareunia underwent to deep endometriosis excision using the new robotic platform HugoTM RAS system at the Unit of Gynaecological Oncology, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.
Intraoperative data, docking set up, post-operative outcomes up to three months follow up were evaluated.
The surgical procedure was carried out without intra-operative or post-operative complications, operative time (OT) was 200 minutes, while docking time was 8 minutes. No system errors or faults in the robotic arms were registered. Post-operative complete disease-related symptoms relief was reported.
According to our results, the introduction of this new robotic platform in the surgical management of deep endometriosis seems to be feasible, especially in advanced cases. However, further studies are needed to demonstrate the benefits of this surgical system and the advantages of robotic surgery compared to laparoscopy in this subset of patients.
The High Efficiency Video Coding (HEVC) standard has recently been extended to support efficient representation of multiview video and depth-based 3D video formats. The multiview extension, MV-HEVC, ...allows efficient coding of multiple camera views and associated auxiliary pictures, and can be implemented by reusing single-layer decoders without changing the block-level processing modules since block-level syntax and decoding processes remain unchanged. Bit rate savings compared with HEVC simulcast are achieved by enabling the use of inter-view references in motion-compensated prediction. The more advanced 3D video extension, 3D-HEVC, targets a coded representation consisting of multiple views and associated depth maps, as required for generating additional intermediate views in advanced 3D displays. Additional bit rate reduction compared with MV-HEVC is achieved by specifying new block-level video coding tools, which explicitly exploit statistical dependencies between video texture and depth and specifically adapt to the properties of depth maps. The technical concepts and features of both extensions are presented in this paper.
Minimally invasive sacral colpopexy is considered the gold standard for surgical treatment of Pelvic Organ Prolapse (POP), combining high success rates with low recurrence risk in comparison to other ...techniques. This is the first case of robotic sacral colpopexy (RSCP) performed with the innovative Hugo™ RAS robotic system.
The aim of this article is to show the surgical steps of a nerve sparing RSCP performed with the new Hugo™ RAS robotic system (Medtronic), by also evaluating the feasibility of this technique using this novel Robotic System.
A 50-year-old Caucasian woman with symptomatic pelvic organ prolapse (POP-Q): Aa: +2, Ba: +3, C: +4, D: +4, Bp: -2, Ap: -2 , TVL:10 GH: 3,5 BP:3 underwent RSCP as well as a subtotal hysterectomy with bilateral salpingo-oophorectomy, using the new surgical robot Hugo™ RAS in the Division of Urogynaecology and Pelvic Reconstructive Surgery, Fondazione Policlinico Universitario A. Gemelli IRCCS, Rome, Italy.
Intraoperative data, docking specifics, objective and subjective outcomes at three months follow up.
Surgical procedure was carried out without intra-operative complications, operative time (OT) was 150 minutes, docking time was 9 minutes. No system errors or faults in the robotic arms were registered. Urogynaecological examination at three months follow up showed a complete resolution of the prolapse.
RSCP using the Hugo™ RAS system seems to be a feasible and effective approach according to results in terms of operative time, cosmetic results, postoperative pain and length of hospitalisation. Large number of case reports as well as longer follow up are mandatory to better define its benefits, advantages, and costs.
Despite the emergence of computer games as a dominant cultural industry (and the accompanying emergence of computer games as the subject of scholarly research), we know little or nothing about the ...ethics of computer games. Considerations of the morality of computer games seldom go beyond intermittent portrayals of them in the mass media as training devices for teenage serial killers. In this first scholarly exploration of the subject, Miguel Sicart addresses broader issues about the ethics of games, the ethics of playing the games, and the ethical responsibilities of game designers. He argues that computer games are ethical objects, that computer game players are ethical agents, and that the ethics of computer games should be seen as a complex network of responsibilities and moral duties. Players should not be considered passive amoral creatures; they reflect, relate, and create with ethical minds. The games they play are ethical systems, with rules that create gameworlds with values at play. Drawing on concepts from philosophy and game studies, Sicart proposes a framework for analyzing the ethics of computer games as both designed objects and player experiences. After presenting his core theoretical arguments and offering a general theory for understanding computer game ethics, Sicart offers case studies examining single-player games (using Bioshock as an example), multiplayer games (illustrated by Defcon), and online gameworlds (illustrated by World of Warcraft) from an ethical perspective. He explores issues raised by unethical content in computer games and its possible effect on players and offers a synthesis of design theory and ethics that could be used as both analytical tool and inspiration in the creation of ethical gameplay.
African cinema in the 1960s originated mainly from Francophone countries. It resembled the art cinema of contemporary Europe and relied on support from the French film industry and the French state. ...Beginning in 1969 the biennial Festival panafricain du cinéma et de la télévision de Ouagadougou (FESPACO), held in Burkina Faso, became the major showcase for these films. But since the early 1990s, a new phenomenon has come to dominate the African cinema world: mass-marketed films shot on less expensive video cameras. These "Nollywood" films, so named because many originate in southern Nigeria, are a thriving industry dominating the world of African cinema. Viewing African Cinema in the Twenty-first Century is the first book to bring together a set of essays offering a comparison of these two main African cinema modes. Contributors: Ralph A.

Upon its premiere in 1992, Midway’s Mortal Kombat spawned an enormously influential series of fighting games, notorious for their violent “fatality” moves performed by photorealistic characters. ...Targeted by lawmakers and moral reformers, the series directly inspired the creation of an industrywide rating system for video games and became a referendum on the wide popularity of 16-bit home consoles. Along the way, it became one of the world’s most iconic fighting games, and formed a transmedia franchise that continues to this day. This book traces Mortal Kombat’s history as an American product inspired by both Japanese video games and Chinese martial-arts cinema, its successes and struggles in adapting to new market trends, and the ongoing influence of its secret-strewn narrative world. After outlining the specific elements of gameplay that differentiated Mortal Kombat from its competitors in the coin-op market, David Church examines the various martial-arts films that inspired its Orientalist imagery, helping explain its stereotypical uses of race and gender. He also posits the games as a cultural landmark from a moment when public policy attempted to intervene in both the remediation of cinematic aesthetics within interactive digital games and in the transition of public gaming spaces into the domestic sphere. Finally, the book explores how the franchise attempted to conquer other forms of media in the 1990s, lost ground to a new generation of 3D games in the 2000s, and has successfully rebooted itself in the 2010s to reclaim its legacy.
Face recognition with still face images has been widely studied, while the research on video-based face recognition is inadequate relatively, especially in terms of benchmark datasets and ...comparisons. Real-world video-based face recognition applications require techniques for three distinct scenarios: 1) Videoto-Still (V2S); 2) Still-to-Video (S2V); and 3) Video-to-Video (V2V), respectively, taking video or still image as query or target. To the best of our knowledge, few datasets and evaluation protocols have benchmarked for all the three scenarios. In order to facilitate the study of this specific topic, this paper contributes a benchmarking and comparative study based on a newly collected still/video face database, named COX 1 Face DB. Specifically, we make three contributions. First, we collect and release a largescale still/video face database to simulate video surveillance with three different video-based face recognition scenarios (i.e., V2S, S2V, and V2V). Second, for benchmarking the three scenarios designed on our database, we review and experimentally compare a number of existing set-based methods. Third, we further propose a novel Point-to-Set Correlation Learning (PSCL) method, and experimentally show that it can be used as a promising baseline method for V2S/S2V face recognition on COX Face DB. Extensive experimental results clearly demonstrate that video-based face recognition needs more efforts, and our COX Face DB is a good benchmark database for evaluation.
In recent years, a collection of new techniques which deal with video as input data, emerged in computer graphics and visualization. In this survey, we report the state of the art in video‐based ...graphics and video visualization. We provide a review of techniques for making photo‐realistic or artistic computer‐generated imagery from videos, as well as methods for creating summary and/or visual representations to reveal important features and events in videos. We provide a new taxonomy to categorize the concepts and techniques in this newly emerged body of knowledge. To support this review, we also give a concise overview of the major advances in automated video analysis, as some techniques in this field (e.g. feature extraction, detection, tracking and so on) have been featured in video‐based modelling and rendering pipelines for graphics and visualization.
