Immersive interconnected virtual and augmented reality : a 5G and IoT perspective

Despite remarkable advances, current augmented and virtual reality (AR/VR) applications are a largely individual and local experience. Interconnected AR/VR, where participants can virtually interact across vast distances, remains a distant dream. The great barrier that stands between current technology and such applications is the stringent end-to-end latency requirement, which should not exceed 20 ms in order to avoid motion sickness and other discomforts. Bringing AR/VR to the next level to enable immersive interconnected AR/VR will require significant advances towards 5G ultra-reliable low-latency communication (URLLC) and a Tactile Internet of Things (IoT). In this article, we articulate the technical challenges to enable a future AR/VR end-to-end architecture, that combines 5G URLLC and Tactile IoT technology to support this next generation of interconnected AR/VR applications. Through the use of IoT sensors and actuators, AR/VR applications will be aware of the environmental and user context, supporting human-centric adaptations of the application logic, and lifelike interactions with the virtual environment. We present potential use cases and the required technological building blocks. For each of them, we delve into the current state of the art and challenges that need to be addressed before the dream of remote AR/VR interaction can become reality

Znaczenie biopsji wątroby w praktyce klinicznej — rekomendacje Sekcji Hepatologicznej Polskiego Towarzystwa Gastroenterologii

Biopsja wątroby mimo wielu ograniczeń jest „złotym standardem” w ocenie stanu tego narządu u pacjentów z chorobami miąższowymi i cholestatycznymi wątroby. Postęp w zrozumieniu zjawisk patofizjologicznych i poznanie historii naturalnej chorób wątroby, jak również pojawienie się nowych metod diagnostycznych o charakterze nieinwazyjnym, zmieniły w ostatnim czasie wskazania do wykonywania biopsji wątroby. Bez względu na te zmiany, histopatologiczna ocena wątroby nadal stanowi podstawę wnioskowania diagnostycznego, rokowniczego i decyzyjnego w kwestii wyboru optymalnej terapii. Artykuł jest zbiorem polskich rekomendacji dotyczących znaczenia biopsji wątroby w praktyce lekarskiej. Celem pracy jest podsumowanie zasad bieżącej praktyki w stosowaniu biopsji wątroby u dorosłych chorych z rozlanymi i ogniskowymi chorobami wątroby. Przedstawiono przegląd wiedzy na temat techniki wykonywania i wskazań do biopsji wątroby. Tematem pracy są również powikłania i przeciwwskazania do wykonywania tego zabiegu

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms

A Generic Knowledge Based Problem Solving Method For Parameter Design

: The paper presents the Complete-Revise-Optimize method which represents a knowledge based problem solving activity aiming for the solution of parameter design problems. The method is characterised by various types of knowledge necessary for its application. It deals only with objects which are generic to particular domain. The presented method consists of various interconnected tasks which contain domain knowledge to map their generic functions to a particular domain. 1. INTRODUCTION Parameter design is a kind of configuration design which represents the selection of components and the composition of these components into a final artefact in order to provide a required functionality of the constructed artefact. Various predefined sets of components with given characteristics are available. Only (some of) these components can participate in the final artefact design. The components can be interconnected in different ways, predefined in advance. From the designer&apos;s point of view not ..

Linear Soft Constraint Satisfaction

Several approaches can be used to solve constrained problems. Unfortunately, most of them cannot process soft constraints which do not limit the solution space but only introduce a measure of acceptance for the space of possible solutions. The violation of a soft constraint does not reject the solution but only signalizes the decreasing quality of this solution (the acceptability of the solution can be preserved). A simple framework based on genetic algorithms with penalty functions enabling to solve problems with soft constraints of the linear form is presented. Keywords: Constraint satisfaction, soft constraints, genetic algorithms, penalty functions. 1 Introduction A broad class of problems can be represented as the class of problems with linear constraints. A typical example of this class of problems is defined as follows: ffl a set of variables X = fx 1 ; x 2 ; : : : ; xn g, ffl a set of linear constraints C = fc 1 ; c 2 ; : : : ; c m g: 8i 2! 1; m ?; MIN i a i1 x 1 + a i2 x 2 ..
