Level crossing sampling (LCS) is a power-efficient analog-to-digital conversion scheme for spikelike signals that arise in many Internet of Things-enabled automotive and environmental monitoring applications. However, LCS scheme requires a dedicated time-to-digital converter with large dynamic range specifications. In this paper, we present a compressed LCS that exploits the signal sparsity in the

To obtain better fluid mixing and higher heat transfer rate in the low Reynolds number regime, various types of fins have been employed for electronic cooling applications. However, previous works showed that there are no remarkable differences in the thermal performance of a straight-plate and a channel with louvered-fins when the Reynolds number is low or moderate. In this paper, the Constructal

The Scandinavian countries have a long history of active labour market policy, using activation to promote work among those with no problems besides unemployment. However, activation policy is now permeating social policies providing economic protection for young adults who cannot work for health reasons, which has been legitimised through a strong emphasis on paid work as the main source of socia

The current paper addresses the implications of doing research on socially assistive robots in real homes. In contrast to laboratory studies, studies of robots in their intended natural environments can provide insights into people’s experiences of robots, and if and how a robot becomes embedded and used in people’s everyday life. However, moving robots out of the lab and into real life environmen

Understanding and managing coupled human and natural systems (CHANS) is a central challenge of the 21st century, but more focus is needed to pursue the most important questions within this vast field given limited research capacity and funding. We present 40 important questions for CHANS research, identified through a two-part crowdsourcing exercise within the CHANS community. We solicited members

Measurements of the production cross section of a Z boson in association with jets in proton–proton collisions at s=13 TeV are presented, using data corresponding to an integrated luminosity of 3.16 fb- 1 collected by the ATLAS experiment at the CERN Large Hadron Collider in 2015. Inclusive and differential cross sections are measured for events containing a Z boson decaying to electrons or muons

Systems whose magnetic response can be finely tuned using control parameters, such as temperature and external magnetic field strength, are extremely desirable, functional materials. Magnetic nanoparticles, in particular suspensions thereof, offer opportunities for this controllability to be realised. Cube-like particles are particularly mono-disperse examples that, together with their favourable

Achieving control of the surface chemistry of colloidal quantum dots (CQDs) is essential to fully exploit their properties in solar cells, but direct measurement of the chemistry and electronic structure in the outermost atomic layers is challenging. Here we probe the surface oxidation and passivation of cation-exchanged PbS/CdS core/shell CQDs with sub nm-scale precision using synchrotron-radiati

One layer thick iron oxide films are attractive from both applied and fundamental science perspectives. The structural and chemical properties of these systems can be tuned by changing the substrate, making them promising materials for heterogeneous catalysis. In the present work, we investigate the structure of FeO(111) monolayer films grown on Ag(100) and Ag(111) substrates by means of microscop

The exclusive charmonium production process in pp annihilation with an associated π0 meson pp→J/ψπ0 is studied in the framework of QCD collinear factorization. The feasibility of measuring this reaction through the J/ψ→e+e- decay channel with the AntiProton ANnihilation at DArmstadt (PANDA) experiment is investigated. Simulations on signal reconstruction efficiency as well as the background reject

This paper deals with those provisions of the new EU Regulation No. 2015/848 on Insolvency Proceedings (Recast) that create a system of national insolvency registers and establish a decentralized system for the interconnection of such registers by means of the European e-Justice Portal.

Timely loss-of-contact detection between devices in pervasive systems using mobile networks is an important aspect for both functionality and user experience. Traditional schemes where time-to-live is defined by the service provider are not adequate in mobile networks where communication failures are frequent. On the other hand, schemes using keep-alive messaging tend to increase the communication

Environmental policy-making increasingly involves ministries beyond environment ministries. In particular, finance ministries are important, since they control the public budget and address environmental issues from a perspective different from environmental actors. The role of finance ministries is especially salient in the European Union's (EU) Emissions Trading System (ETS), which has been subj

That big tobacco hinders the adoption of anti-smoking legislation is no surprise. Your leader correctly identifies the best route to behavioural change – shareholder pressure – but does not highlight the key channel to achieve this. Big tobacco needs to diversify. This is where shareholder pressure should be applied: to encourage manufacturers and associated leaf merchants to invest in non-harmful

With the advent of IoT and the associated variety of pervasive and context-aware applications, there is an increasing requirement to support the execution of these applications on devices with limited processing power. This is a cost-intensive process as this usually requires the deployment of centralized computing infrastructure accessible via a cloud interface. We envision a distributed executio

Identifying the genes and pathways that regulate self-renewal and differentiation in somatic stem cells is a central goal in stem cell and cancer biology. Here, we describe a method for RNA interference (RNAi)-based screens combined with next-generation sequencing (NGS) in primary human hematopoietic stem and progenitor cells (HSPCs). These cells are suitable targets for complex, selection-based s

For decades, scientists and engineers have strived to design means of assembling colloids into ordered structures. By now, the literature is quite peppered with reports of colloidal assemblies. However, the available methods can assemble only a narrow range of structures or are applicable to specific types of colloids. There are still only few generic methods that would lead to arbitrary colloidal

We outline a conceptual strategy for implementing conservation interventionsin a multiscale, multiactor, and multilevel governance world. Using farmlandas an example, we argue that conservation interventions should be implementedwithin a multiscale framework of guiding ecological principles. Inthis context, findings from multilevel governance research can inform a nuancedunderstanding of the role

Radioactive sources such as nuclear power installations can pose a great threat to both humans and our environment. How do we measure, model and regulate such threats? Environmental Radioactivity and Emergency Preparedness addresses these topical questions and aims to plug the gap in the lack of comprehensive literature in this field.The book explores how to deal with the threats posed by differen
