SAMPLED: Shared Anonymous Music PLayback using wirelEss Devices

Recent advances in mobile computing enable many new applications, yet at the same time create privacy implications caused by the increasing amount of data that becomes available. This thesis will explore the possibilities of wireless-enabled portable devices and their attending privacy implications. We will describe how such a device containing personal information about the musical preferences of its user can help improve the user\u27s experience in a social setting where music is played for all, and at the same time preserve each user\u27s privacy

Maritime transport and regional climate change impacts in large EU islands and archipelagos

Maritime transport is a vital sector for global trade and the world economy. Particularly for islands, there is also an important social dimension of this sector, since island communities strongly rely on it for a connection with the mainland and the transportation of goods and passengers. Furthermore, islands are exceptionally vulnerable to climate change, as the rising sea level and extreme events are expected to induce severe impacts. Such hazards are anticipated to also affect the operations of the maritime transport sector by affecting either the port infrastructure or ships en route. The present study is an effort to better comprehend and assess the future risk of maritime transport disruption in six European islands and archipelagos, and it aims at supporting regional to local policy and decision-making. We employ state-of-the-art regional climate datasets and the widely used impact chain approach to identify the different components that might drive such risks. Larger islands (e.g., Corsica, Cyprus and Crete) are found to be more resilient to the impacts of climate change on maritime operations. Our findings also highlight the importance of adopting a low-emission pathway, since this will keep the risk of maritime transport disruption similar to present levels or even slightly decreased for some islands because of an enhanced adaptation capacity and advantageous demographic changes.Open Access funding enabled and organized by Projekt DEAL.This work has received funding from the European Union’s H2020 Research and Innovation Programme under grant agreement no. 776661 (SOCLIMPACT project).

2007 Dynamic Tree Switching for IP Networks UNIVERSITY OF LONDON ABSTRACT Dynamic Tree Switching for IP Networks

Multi-Protocol Label Switching (MPLS) provides a flexible forwarding mechanism for traffic engineering in data networks. A valuable way of further simplifying the forwarding process, particularly within IP networks is through the use of multipoint-to-point label switched paths (LSPs). The use of multipoint-to-point (MP2P) LSPs in this way was identified in even the earliest IETF drafts of MPLS. Whilst some previous work addressed the formulation of such multipoint-to-point (MP2P) LSPs, only a few schemes have been proposed and it is recognised that the formation of such LSPs is non trivial. Furthermore, resilience in such configurations has only been partially addressed. In this thesis, the notion of Dynamically Adaptive Multipoint to Point LSPs is presented whereby the MP2P LSPs are created and maintained dynamically. A new scheme (for the online creation and maintenance of MP2P LSPs) called Dynamically Adaptive Multipoint to Point (DAM) is presented. In DAM, MP2P LSPs are maintained by the exploitation of ad-hoc algorithms that can lead to fast localised healing. DAM, as part of its restoration strategy, supports a Directed Acyclic Graph (DAG). The multipath nature of this DAG has been used to formulate a load balancing strategy for use in supporting multiple overlaid MP2P LSPs

Dynamically Adaptive Mulitipoint to Point LSPs

Abstract: Multi-Protocol Label Switching provides a flexible forwarding mechanism within communication networks. Since its inception at the end of the last century it has been recognised that multipoint-to-point label switched paths offer a valuable way of further simplifying the forwarding process particularly within IP networks. Whilst work has been carried out into schemes for the formulation of such multipoint-to-point LSPs, only a couple of schemes have been proposed. Furthermore resilience in such configurations has only been partially addressed. This paper describes an improved method for the formulation of multipoint-to-point LSPs. In addition, the new notion of Dynamically Adaptive Mulitipoint to Point LSPs is presented in order to address the issue of resilience.

A review of the application of fuzzy cognitive maps in the policy decision-making life cycle

Fuzzy cognitive maps are a qualitative modeling technique that uses expert knowledge to attempt to represent the interactions between problem-specific factors aiming to simulate how these interactions alter the factors and drive the current state of a problem to a different state. Recent years have seen an increase in the number of research attempts that propose the adoption of Fuzzy cognitive maps (FCMs) as a means to forecast the effect of a policy in a number of interesting domains, including land use, urban (re)development, and other social, political, or economic issues or to simulate the current state of affairs to pinpoint possible hotspots for creating a policy. This chapter presents an overview of these research attempts where fuzzy cognitive maps have been employed as a simulation tool in order to support decision makers in their assessment of the impact of policies and help them adopt the most suitable policy to implement

User Acceptance of Technology: Statistical Analysis of Training’s Impact on Local Government Employees’ Perceived Usefulness and Perceived Ease-of-Use

This article investigates how training public officials from two municipalities in Spain and Cyprus with new technologies affects three dependent variables: level of understanding of the technological innovation being introduced, its perceived usefulness, and its perceived ease-of-use. The tests to determine the impact of training were carried out by means of a self-constructed questionnaire within a repeated measure experimental design. The results demonstrate that the three variables are indeed positively affected by the training sessions to users from both municipalities. Consequently, training plays a vital role in encouraging government employees and administrators to accept, adopt and utilize e-government technologies

Inkjet-printed polymer-fullerene blends for organic electronic applications

Organic field effect transistors, photodiodes and solar cells based on polymer-fullerene blend active layers are printed electronic applications under intense studies. We show that the viscosity of the inkjet formulation, substrate temperature, drop spacing and the height of the droplet in relation to the surface are critical parameters to achieving high quality inkjet-printed polymer-fullerene based active layers. The effect of the above processing parameters on the performance of polymer-fullerene based organic solar cells is presente

Dynamic monitoring of PD‐L1 and Ki67 in circulating tumor cells of metastatic non‐small cell lung cancer patients treated with pembrolizumab

Programmed cell death protein ligand‐1 (PD‐L1) expression in non‐small cell lung cancer (NSCLC) tumors guides treatment selection. PD‐L1 expression in circulating tumor cells (CTCs) may provide further information. We have explored PD‐L1 and marker of proliferation Ki‐67 (Ki67; also known as MKI67) in CTCs in longitudinal samples of 47 advanced NSCLC patients receiving pembrolizumab. A triple immunofluorescence, against cytokeratin, PD‐L1, and Ki67, was performed on peripheral blood mononuclear cells, at baseline, post‐first cycle, post‐third, and primary resistance (PMR). Patients displaying PMR (progression at first evaluation) were classified as progressive disease (PD) and those with clinical benefit as disease control (DC). CTCs were categorized as PD‐L1high/low/medium/negative and Ki67+ or Ki67−. CTC evaluation revealed a significant increase in the PD‐L1low CTC rate at PMR compared to baseline (2.5% at baseline vs. 36.5% at PMR), whereas a reduction in the PD‐L1high CTC rate was observed (31.5% vs. 0%, respectively). Investigation of CTC status between PD and DC patients showed that PD patients more frequently increased total and PD‐L1low CTCs after first cycle compared to DC (83% of PD vs. 37% of DC and 67% of PD vs. 8% of DC, respectively). Progression‐free survival (PFS) was longer in patients with decreased total and PD‐L1low CTCs after first cycle compared to those with increased CTCs (median PFS: not reached vs. 2 months). PD‐L1+ patients presenting a high Ki67 index (% Ki67+ CTCs > 30%) before treatment had a shorter PFS compared to those with a low Ki67 (≤ 30%), and overall survival (OS) was shorter in PD‐L1+ patients harboring Ki67+ CTCs compared to those not presenting (median OS: 11.8 months vs. 33.1 months, respectively). In sequential samples of patients with a durable benefit, a low Ki67 index was observed. Our results suggest that monitoring PD‐L1 and Ki67 expression in CTCs of NSCLC patients treated with pembrolizumab may be predictive for pembrolizumab efficacy
