Large scale manufacturing route to metamaterial coatings using thermal spray techniques and their response to solar radiation

Nadimul Faisal, Nazmi Sellami, Federico Venturi, Tanvir Hussain, Tapas Mallick, Firdaus Muhammad-Sukki, Alex Bishop, Hari Upadhyaya, Nirmal Kumar Katiyar & Saurav Goel
Metamaterials, an artificial periodic two- or three-dimensional configuration can change propagation characteristics of electromagnetic waves (i.e., reflection, transmission, absorption). The current challenges in the field of metamaterial coatings are their manufacturing in large scale and large length scale. There is a clear need to enhance process technologies and scalability of these. Thermal spraying is a method used to deposit small to large scale coatings where the sprayed layer is typically formed by successive impact of...

Data from: Deliberation favours social efficiency by making people disregard their relative shares: evidence from USA and India

Valerio Capraro, Brice Corgnet, Antonio M. Espín & Roberto Hernán-González
Groups make decisions on both the production and the distribution of resources. These decisions typically involve a tension between increasing the total level of group resources (i.e. social efficiency) and distributing these resources among group members (i.e. individuals' relative shares). This is the case because the redistribution process may destroy part of the resources, thus resulting in socially inefficient allocations. Here we apply a dual-process approach to understand the cognitive underpinnings of this fundamental tension....

Data from: Measuring the immune system of the three-spined stickleback - examining natural variation in the laboratory and the wild

Shaun Robertson, Janette E. Bradley, Andrew D.C. MacColl & Andrew D. C. MacColl
Current understanding of the immune system comes primarily from laboratory-based studies. There has been substantial interest in examining how it functions in the wild, but studies have been limited by a lack of appropriate assays and study species. The three-spined stickleback (Gasterosteus aculeatus L.) provides an ideal system in which to advance the study of wild immunology, but requires the development of suitable immune assays. We demonstrate that meaningful variation in the immune response of...

Data from: The roles of contact conformity, temperature and displacement amplitude on the lubricated fretting wear of a steel-on-steel contact

Austin R. Warmuth, Wei Sun & Philip H. Shipway
This paper investigates the effect of contact geometry, temperature and displacement amplitude on the fretting behaviour of an aero-turbo oil lubricated cylinder-on-flat contact. To be effective, the lubricant needed both to penetrate the contact and then offer protection. Lubricant penetration into the fretting contact is found to be controlled by two physical parameters, namely (i) the width of the contact that remains covered throughout the fretting test and (ii) the lubricant viscosity. The protection offered...

Abdussamad, Margarethe Uerpmann, Hans-Peter Uerpmann, Bea De Cupere, Peter Magee, Majed A. Alnaqeeb, Bashir Salim, Abdul Raziq, Tadelle Dessie, Omer M. Abdelhadi, Mohammad H. Banabazi, Marzook Al-Eknah, Chris Walzer, Bernard Faye, Michael Hofreiter, Joris Peters, Olivier Hanotte & Pamela A. Burger
Dromedaries have been fundamental to the development of human societies in arid landscapes and for long-distance trade across hostile hot terrains for 3,000 y. Today they continue to be an important livestock resource in marginal agro-ecological zones. However, the history of dromedary domestication and the influence of ancient trading networks on their genetic structure have remained elusive. We combined ancient DNA sequences of wild and early-domesticated dromedary samples from arid regions with nuclear microsatellite and...

Data from: Impact of person-centred care training and person-centred activities on quality of life, agitation, and antipsychotic use in people with dementia living in nursing homes: a cluster-randomised controlled trial

Clive Ballard, Anne Corbett, Martin Orrell, Gareth Williams, Esme Moniz-Cook, Renee Romeo, Bob Woods, Lucy Garrod, Ingelin Testad, Barbara Woodward-Carlton, Jennifer Wenborn, Martin Knapp & Jane Fossey
Background: Agitation is a common, challenging symptom affecting large numbers of people with dementia and impacting on quality of life (QoL). There is an urgent need for evidence-based, cost-effective psychosocial interventions to improve these outcomes, particularly in the absence of safe, effective pharmacological therapies. This study aimed evaluate the efficacy of a person-centered care and psychosocial intervention (WHELD) on QoL, agitation and antipsychotic use in people with dementia living in nursing homes, and to determine...

Data from: Species integrity enhanced by a predation cost to hybrids in the wild

P. Anders Nilsson, Kaj Hulthén, Ben B. Chapman, Lars-Anders Hansson, Jakob Brodersen, Henrik Baktoft, Jerker Vinterstare, Christer Brőnmark & Christian Skov
Species integrity can be challenged, and even eroded, if closely related species can hybridize and produce fertile offspring of comparable fitness to that of parental species. The maintenance of newly diverged or closely related species therefore hinges on the establishment and effectiveness of pre- and/or post-zygotic reproductive barriers. Ecological selection, including predation, is often presumed to contribute to reduced hybrid fitness, but field evidence for a predation cost to hybridization remains elusive. Here we provide...

Data from: Alien honeybees increase pollination risks for range-restricted plants

Olivia Norfolk, Francis Gilbert & Markus P. Eichhorn
Aim Range-restricted species are of high conservation concern, and the way in which they interact with more widespread species has implications for their persistence. Here, we determine how the specialization of mutualistic interactions varies with respect to the geographic range size of plants and pollinators and assess how they respond to the introduction of the alien honeybee. We also compare network characteristics (connectance, specialization and nestedness) between an invaded low mountain and non-invaded high mountain...

Rethinking megafauna

Marcos Moleón, José Sánchez-Zapata, José Donázar, Eloy Revilla, Berta Martín-López, Cayetano Gutiérrez-Cánovas, Wayne Getz, Zebensui Morales-Reyes, Ahimsa Campos-Arceiz, Larry Crowder, Mauro Galetti, Manuela González-Suárez, Fengzhi He, Pedro Jordano, Rebecca Lewison, Robin Naidoo, Norman Owen-Smith, Nuria Selva, Jens-Christian Svenning, José Tella, Christiane Zarfl, Sonja Jähnig, Matt Hayward, Søren Faurby, Nuria García … & Klement Tochner
Concern for megafauna is increasing among scientists and non-scientists. Many studies have emphasized that megafauna play prominent ecological roles and provide important ecosystem services to humanity. But, what precisely are “megafauna”? Here we critically assess the concept of megafauna and propose a goal-oriented framework for megafaunal research. First, we review definitions of megafauna and analyze associated terminology in the scientific literature. Second, we conduct a survey among ecologists and paleontologists to assess the species traits...

The clinical impact of high-profile animal-based research reported in the UK national press: a detailed discussion of articles from 1995, and full search results from the Nexis database

Jarrod Bailey & Michael Balls
Objectives: We evaluated animal-based biomedical ‘breakthroughs’ reported in the UK national press in 1995 (25 years prior to the conclusion of this study). Based on evidence of over-speculative reporting of biomedical research in other areas (e.g. press releases and scientific papers), we specifically examined animal research in the media, asking, “In a given year, what proportion of animal research ‘breakthroughs’ published in the UK national press had translated, more than 20 years later, to approved...

Data from: Telenomus nizwaensis (Hymenoptera: Scelionidae), an important egg parasitoid of the pomegranate butterfly Deudorix livia Klug (Lepidoptera: Lycaenidae) in Oman

A. Polaszek, A. Al-Riyami, Z. Lahey, S. A. Al-Khatri, R. H. Al-Shidi & I. C. W. Hardy
The pomegranate butterfly Deudorix (=Virachola) livia is the major pest of pomegranate, a crop of economic importance, in Oman. A species of parasitoid wasp in the hymenopteran family Scelionidae is responsible for high levels of mortality of its eggs. This wasp is described herein as Telenomus nizwaensis Polaszek sp. n. based on morphology and DNA sequence data. Telenomus nizwaensis is currently known only from D. livia, which is also a pest of economic importance on...

Data from: Epigenetic memory via concordant DNA methylation is inversely correlated to developmental potential of mammalian cells

Minseung Choi, Diane P. Genereux, Jamie Goodson, Haneen Al-Azzawi, Shannon Q. Allain, Noah Simon, Stan Palasek, Carol B. Ware, Chris Cavanaugh, Daniel G. Miller, Winslow C. Johnson, Kevin D. Sinclair, Reinhard Stöger & Charles D. Laird
In storing and transmitting epigenetic information, organisms must balance the need to maintain information about past conditions with the capacity to respond to information in their current and future environments. Some of this information is encoded by DNA methylation, which can be transmitted with variable fidelity from parent to daughter strand. High fidelity confers strong pattern matching between the strands of individual DNA molecules and thus pattern stability over rounds of DNA replication; lower fidelity...

Data from: Experimental measurements of water molecule binding energies for the second and third solvation shells of [Ca(H2O)n]2+ complexes

Eleonora Bruzzi & Anthony J. Stace
Further understanding of the biological role of the Ca2+ ion in an aqueous environment requires quantitative measurements of both the short- and long-range interactions experienced by the ion in an aqueous medium. Here, we present experimental measurements of binding energies for water molecules occupying the second and, quite possibly, the third solvation shell surrounding a central Ca2+ ion in [Ca(H2O)n]2+ complexes. Results for these large, previously inaccessible, complexes have come from the application of finite...

Data from: Effect of lianas on forest-level tree carbon accumulation does not differ between seasons: results from a liana removal experiment in Panama

Geertje M.F. Van Der Heijden, Jennifer S. Powers & Stefan A. Schnitzer
1. Lianas are prevalent in Neotropical forests, where liana-tree competition can be intense, resulting in reduced tree growth and survival. The ability of lianas to grow relative to trees during the dry season suggests that liana-tree competition is also strongest in the dry season. If correct, the predicted intensification of the drying trend over large areas of the tropics in the future may therefore intensify liana-tree competition, resulting in a reduced carbon sink function of...

Data from: Dispositional free riders do not free ride on punishment

Till O. Weber, Ori Weisel & Simon Gächter
Strong reciprocity explains prosocial cooperation by the presence of individuals who incur costs to help those who helped them (‘strong positive reciprocity’) and to punish those who wronged them (‘strong negative reciprocity’). Theories of social preferences predict that in contrast to ‘strong reciprocators’, self-regarding people cooperate and punish only if there are sufficient future benefits. Here, we test this prediction in a two-stage design. First, participants are classified according to their disposition towards strong positive...

Data from: Individual boldness is linked with protective shell shape in aquatic snails

Johan Ahlgren, Ben B. Chapman, P. Anders Nilsson, Christer Brönmark & C. Bronmark
The existence of consistent individual differences in behaviour (‘animal personality’) has been well documented in recent years. However, how such individual variation in behaviour is maintained over evolutionary time is an ongoing conundrum. A well-studied axis of animal personality is individual variation along a bold–shy continuum, where individuals differ consistently in their propensity to take risks. A predation-risk cost to boldness is often assumed, but also that the reproductive benefits associated with boldness lead to...

Data from: Sex-specific responses of phenotypic diversity to environmental variation

Adam C. Algar & Marta Lopez-Darias
Identifying the factors generating ecomorphological diversity within species can provide a window into the nascent stages of ecological radiation. Sexual dimorphism is an obvious axis of intraspecific morphological diversity that could affect how environmental variation leads to ecological divergence among populations. In this paper we test for sex-specific responses in how environmental variation generates phenotypic diversity within species, using the generalist lizard Gallotia galloti on Tenerife (Canary Islands). We evaluate two hypotheses: the first proposes...

Data from: Community-wide scan identifies fish species associated with coral reef services across the Indo-Pacific

Eva Maire, Sébastien Villéger, Nicholas A.J. Graham, Andrew S. Hoey, Joshua Cinner, Sebastian C.A. Ferse, Catherine Aliaume, David J. Booth, David A. Feary, Michel Kulbicki, Stuart A. Sandin, Laurent Vigliola, David Mouillot & Sebastian C. A. Ferse
Determining whether many functionally complementary species or only a subset of key species are necessary to maintain ecosystem functioning and services is a critical question in community ecology and biodiversity conservation. Identifying such key species remains challenging, especially in the tropics where many species co-occur and can potentially support the same or different processes. Here, we developed a new community-wide scan (CWS) approach, analogous to the genome-wide scan, to identify fish species that significantly contribute,...
