5 - The structure of silk

A key feature of silk fibres is the carefully controlled assembly and directed growth that produce hierarchical structures at all length scales. The final result is a material of outstanding strength, functional flexibility and often with self-healing properties. Some salient results in silk research are reviewed to identify the fundamental ‘bio-principles’ that make silk a remarkable system to st

IDENTIFYING DIFFERENTIATING FEATURES BETWEEN NORMAL AND TORN ROTATOR CUFF TENDONS USING FOURIER TRANSFORM INFRARED SPECTROSCOPY

Background: Up to one third of adults have been estimated to have rotator cuff tendon (RCT) tears. Larger RCT tears are associated with poorer scores and function, and are more likely to re-rupture after surgical repairs, hence there is a need for earlier identification and treatment. The aim of this study was to identify biomarkers of RCT tear pathologies to aid accurate identification and monito

DETERMINING CHEMICAL DIFFERENCES BETWEEN TORN AND NORMAL ROTATOR CUFF TENDONS USING FOURIER TRANSFORM INFRARED SPECTROSCOPY

BackgroundRotator cuff tears pose a huge socioeconomic burden. Our study uses Fourier transform infrared spectroscopy (FTIR) as it is a quick, non-manipulative and non-destructive test, which can identify a wide range of chemical targets from small intraoperatively obtained specimens. The aim of this study was (i) to characterise the chemical and structural composition of rotator cuff tendons and

The relevance of silks to amyloids

At the heart of protein's aggregation are specific molecular events; and how they are modulated by changes in solvent conditions and temperature is key to our understanding and control of aggregation. A certain class of structural fibrous proteins may provide the answer. Indeed, spider silk and silkworm silk proteins have evolved to readily form ‘insoluble’ ordered structures. But, to date little

Svensk forskning i musik – de senaste 100 åren

This article aims to offer an overview of the rise, growth and diversification of academic music research in Sweden. ‘Research in music’ is suggested as a comprehensive term, covering all kinds of research relating to music.In 1915 the Swedish University Chancellor’s office established a syllabus for ‘music history and theory’ at Lund University. The syllabus was initiated by Tobias Norlind, and i

Mapping geographical inequalities in childhood diarrhoeal morbidity and mortality in low-income and middle-income countries, 2000-17 : analysis for the Global Burden of Disease Study 2017

BACKGROUND: Across low-income and middle-income countries (LMICs), one in ten deaths in children younger than 5 years is attributable to diarrhoea. The substantial between-country variation in both diarrhoea incidence and mortality is attributable to interventions that protect children, prevent infection, and treat disease. Identifying subnational regions with the highest burden and mapping associ

Towards intelligent Industry 4.0 5G networks: A first throughput and QoE measurement campaign

5G promises to usher in the industrial 4.0 era. In that era, intricately managed autonomous industrial sites with for example remotely controller equipment and autonomous units promise previously unseen levels of efficiency. Although such scenarios are elusive, they come with strict long-since established safety requirements. To uphold such requirements, intelligent industrial 5G networks, that ac

Chapter 15: Circular economy and sustainable consumption: Suggestions for ethical marketing

Currently there is an ongoing push towards a circular economy. Governments, the EU, green NGOs, think-tanks, companies and their industry organizations are all advocating more circular solutions meaning that the current linear take-make-use-lose model of consumption should be replaced with a reuse-repair-recycle circular model. The circular economy is being heralded as one of the main, if not the

Prediagnostic serum polychlorinated biphenyl concentrations and primary liver cancer : A case-control study nested within two prospective cohorts

Background: Polychlorinated biphenyls (PCBs) were used in electrical equipment and a range of construction materials. Although banned in the United States and most of Europe in the 1970s, they are highly persistent in the environment and bioaccumulate. Whether PCBs are associated with liver cancer risk at general population levels is unknown. Methods: This study consisted of 136 incident liver can

Linton, Magnus, 2019. Text & Stil. Om konsten att berätta med vetenskap.

Recension av Magnus Linton, Text & Stil. Om konsten att berätta med vetenskap. Bedömningen är avgjort positiv. Linton har skrivit en träffande, relevant, adekvat bok för alla som skriver sakprosa – samhälls- och kulturvetare, humanister, essäister. Boken är full av exempel och mindre full av goda råd. Den är därtill mycket välskriven och välkomponerad.

Transient gain of function of cannabinoid CB1 receptors in the control of frontocortical glucose consumption in a rat model of Type-1 diabetes

Here we aimed to unify some previous controversial reports on changes in both cannabinoid CB1 receptor (CB1R) expression and glucose metabolism in the forebrain of rodent models of diabetes. We determined how glucose metabolism and its modulation by CB1R ligands evolve in the frontal cortex of young adult male Wistar rats, in the first 8 weeks of streptozotocin-induced type-1 diabetes (T1D). We re

Impact of etcd deployment on Kubernetes, Istio, and application performance

This experience article describes lessons learned as we conducted experiments in a Kubernetes‐based environment, the most notable of which was that the performance of both the Kubernetes control plane and the deployed application depends strongly and in unexpected ways on the performance of the etcd database. The article contains (a) detailed descriptions of how networking with and without Istio w

Adaptive and Application-agnostic Caching in Service Meshes for Resilient Cloud Applications

Service meshes factor out code dealing with inter-micro-service communication. The overall resilience of a cloud application is improved if constituent micro-services return stale data, instead of no data at all. This paper proposes and implements application agnostic caching for micro services. While caching is widely employed for serving web service traffic, its usage in inter-micro-service comm

Control-over-the-cloud: A performance study for cloud-native, critical control systems

In the Industry 4.0 era, time-sensitive and missioncritical control applications still have a long way to go, from being tied down and co-located with the systems they control, to taking full advantage of the cloud. Conservatively keeping applications local will deprive these complex applications of abundantcompute capacity, wider system integration, and the potential for collaborative control eff

Centralized Coordination of Autonomous Vehicles at Intersections

Recent advances in autonomous vehicles present new opportunities in Intelligent transportation systems (ITS) to address urban transport challenges. Therefore, urban traffic scenarios, and in particular intersections as a bottleneck of transportation network, has received significant attention. In this paper we investigate intelligent traffic control mechanisms for autonomous vehicles at intersecti

Massive MIMO Pilot Scheduling over Cloud RAN for Industry 4.0

Cloud-RAN (C-RAN) is a promising paradigm for the next generation radio access network infrastructure, which offers centralized and coordinated base-band signal processing in a BBU pool. This requires extremely low latency fronthaul links to achieve real-time signal processing. In this paper, we investigate massive MIMO pilot scheduling in a C-RAN infrastructure under a factory automation scenario

Electromagnetic Side-Channel Attack on AES using Low-end Equipment

Side-channel attacks on cryptographic algorithms targets the implementation of the algorithm. Information can leak from the implementation in several different ways and, in this paper, electromagnetic radiation from an FPGA is considered. We examine to which extent key information from an AES implementation can be deduced using a low-end oscilloscope. Moreover, we examine how the antenna's distanc
