IoT and Its Implications for Informed Consent

This report is based on a three-hour long workshop between representatives of the PETRAS IoT Hub, Pinsent Masons, and the HMG Department for Transport. The workshop is part of an ongoing investigation that explores the connections between some of the different dimensions likely to shape conceptions and applications of consent in the emerging Internet of Things (IoT). The impetus for the workshop was the recognition that two significant developments will challenge conventional approaches to online consent. From a technical perspective, the IoT will significantly increase personal data collection, use and re-use. From a regulatory perspective, the General Data Protection Regulation (GDPR) which comes into force in May 2018, will make much higher demands on practices of giving and obtaining consent. Combined, these two factors suggest that consent will be a major issue for all actors in the next five years and it requires some careful analysis now in order to adequately prepare for these developments

Sequence Dependence of Self-Interacting Random Chains

We study the thermodynamic behavior of the random chain model proposed by Iori, Marinari and Parisi, and how this depends on the actual sequence of interactions along the chain. The properties of randomly chosen sequences are compared to those of designed ones, obtained through a simulated annealing procedure in sequence space. We show that the transition to the folded phase takes place at a smaller strength of the quenched disorder for designed sequences. As a result, folding can be relatively fast for these sequences.Comment: 14 pages, uuencoded compressed postscript fil

Standardising a moving target: The development and evolution of IoT security standards

The standards landscape for IoT security is currently developing in a fragmented manner. This paper provides a review of the main IoT security standards and guidelines that have been developed by formal standardisation organisations and transnational industry associations and interest alliances to date. The review makes three main contributions to the study of current IoT standards-development processes. First, governments and regulatory agencies in the EU and the US are increasingly considering the promotion of baseline IoT security requirements, achieved through public procurement obligations and cybersecurity certification schemes. Second, the analysis reveals that the IoT security standards landscape is dominated by de facto standards initiated by a diverse range of industry associations across the IoT ecosystem. Third, the paper identifies a number of key challenges for IoT security standardisation, most notably: a) the difficulty of setting a baseline for IoT security across all IoT applications and domains; and b) the difficulty of monitoring the adoption, implementation and effectiveness of IoT security standards and best practices. The paper consequently contributes to a better understanding of the evolution of IoT security standards and proposes a more coherent standards development and deployment approach

The second season of excavations at Jebel Moya (south-central Sudan)

This report presents the latest data from ongoing excavations at Jebel Moya, Sudan. This year saw the opening of five new trenches and continued excavation of an archaeologically rich trench. We have recovered four individual burials, a mud brick wall and a number of animal and archaeobotanical remains. The excavations also yielded a longer pottery sequence, showing clearly that the site was in use by at least the sixth millennium BC. This season confirms the long and complex history of Jebel Moya and provides the material for future studies on population health and subsistence. This season also saw an increase in community engagement and a more detailed study of the various historical trajectories that make up the biography of Jebel Moya

Strong Pinning and Plastic Deformations of the Vortex Lattice

We investigate numerically the dynamically generated plastic deformations of a 3D vortex lattice (VL) driven through a disorder potential with isolated, strong pinning centers (point-like or extended along the field direction). We find that the VL exhibits a very peculiar dynamical behavior in the plastic flow regime, in particular, topological excitations consisting of three or four entangled vortices are formed. We determine the critical current density $j_c$ and the activation energy for depinning $U_c$ in the presence of a finite density of strong pinning centers.Comment: 12 pages, TeX type, Postscript figure

The DLV System for Knowledge Representation and Reasoning

This paper presents the DLV system, which is widely considered the state-of-the-art implementation of disjunctive logic programming, and addresses several aspects. As for problem solving, we provide a formal definition of its kernel language, function-free disjunctive logic programs (also known as disjunctive datalog), extended by weak constraints, which are a powerful tool to express optimization problems. We then illustrate the usage of DLV as a tool for knowledge representation and reasoning, describing a new declarative programming methodology which allows one to encode complex problems (up to $\Delta^P_3$-complete problems) in a declarative fashion. On the foundational side, we provide a detailed analysis of the computational complexity of the language of DLV, and by deriving new complexity results we chart a complete picture of the complexity of this language and important fragments thereof. Furthermore, we illustrate the general architecture of the DLV system which has been influenced by these results. As for applications, we overview application front-ends which have been developed on top of DLV to solve specific knowledge representation tasks, and we briefly describe the main international projects investigating the potential of the system for industrial exploitation. Finally, we report about thorough experimentation and benchmarking, which has been carried out to assess the efficiency of the system. The experimental results confirm the solidity of DLV and highlight its potential for emerging application areas like knowledge management and information integration.Comment: 56 pages, 9 figures, 6 table

Efficacy of boceprevir, an NS3 protease inhibitor, in combination with peginterferon alfa-2b and ribavirin in treatment-naive patients with genotype 1 hepatitis C infection (SPRINT-1): an open-label, randomised, multicentre phase 2 trial

Peginterferon plus ribavirin achieves sustained virological response (SVR) in fewer than half of patients with genotype 1 chronic hepatitis C virus infection treated for 48 weeks. We tested the efficacy of boceprevir, an NS3 hepatitis C virus oral protease inhibitor, when added to peginterferon alfa-2b and ribavirin. In part 1 of this trial, undertaken in 67 sites in the USA, Canada, and Europe, 520 treatment-naive patients with genotype 1 hepatitis C virus infection were randomly assigned to receive peginterferon alfa-2b 1·5 μg/kg plus ribavirin 800–1400 mg daily for 48 weeks (PR48; n=104); peginterferon alfa-2b and ribavirin daily for 4 weeks, followed by peginterferon alfa-2b, ribavirin, and boceprevir 800 mg three times a day for 24 weeks (PR4/PRB24; n=103) or 44 weeks (PR4/PRB44; n=103); or peginterferon alfa-2b, ribavirin, and boceprevir three times a day for 28 weeks (PRB28; n=107) or 48 weeks (PRB48; n=103). In part 2, 75 patients were randomly assigned to receive either PRB48 (n=16) or low-dose ribavirin (400–1000 mg) plus peginterferon alfa-2b and boceprevir three times a day for 48 weeks (low-dose PRB48; n=59). Randomisation was by computer-generated code, and study personnel and patients were not masked to group assignment. The primary endpoint was SVR 24 weeks after treatment. Analysis was by intention to treat. This study is registered with ClinicalTrials.gov, number NCT00423670. Patients in all four boceprevir groups had higher rates of SVR than did the control group (58/107 [54%, 95% CI 44–64], p=0·013 for PRB28; 58/103 [56%, 44–66], p=0·005 for PR4/PRB24; 69/103 [67%, 57–76], p<0·0001 for PRB48; and 77/103 [75%, 65–83], p<0·0001 for PR4/PRB44; vs 39/104 [38%, 28–48] for PR48 control). Low-dose ribavirin was associated with a high rate of viral breakthrough (16/59 [27%]), and a rate of relapse (six of 27 [22%]) similar to control (12/51 [24%]). Boceprevir-based groups had higher rates of anaemia (227/416 [55%] vs 35/104 [34%]) and dysgeusia (111/416 [27%] vs nine of 104 [9%]) than did the control group. In patients with untreated genotype 1 chronic hepatitis C infection, the addition of the direct-acting antiviral agent boceprevir to standard treatment with peginterferon and ribavirin after a 4-week lead-in seems to have the potential to double the sustained response rate compared with that recorded with standard treatment alone.
