Field, coherence and connectedness: Models, methodologies and actions for flowing moistmedia art
Authors: Nóbrega (Guto Nóbrega) Carlos Augusto Moreira da , Fragoso (MALU FRAGOSO) Maria Luiza P. Guimarães 
Published: August 2015

Abstract
This article introduces practical and theoretical investigations in fields of art and technology related to biotelematics, hybridization and transcultural experimentation based on research carried out over the last four years at the Nucleus of Art and New Organisms (NANO). We will approach this subject by considering three main points of view: field theory (Ascott 1980; Nóbrega 2009); the concept of coherence (Ho 1993; Ho & Popp 1989; Simondon 1980); and the state of connectedness (Ascott 2006). These will act as integrative models for the understanding of an emerging hybrid organic structure presented as an aesthetic organism (Nóbrega 2009). The concept of field theory is applied as a working model for the systemic role of information within the immaterial, invisible, dynamical flow that intercommunicates natural (i.e. humans and other living systems) and artificial (i.e. machine) organisms in the process of invention, as well as in the fruition of artwork. In terms of the concept of coherence, we propose the idea of artworks as transducers of energy; more specifically, as resonators of coherent fields that interconnect the artist and audience in an integrated, dynamical whole. Furthermore, we approach the state of connectedness as a fundamental notion for the dynamics involved in the invention, exhibition and absorption of contemporary artworks. NANO Lab’s involvement with artistic research is not only understood as a physical space for experimentation, but also as an environment in which our practice reflects concepts applied in artistic work. In this sense, we can highlight two theoretical references (other than Roy Ascott’s work) which guide this methodology: Humberto Maturana (2001; Varela & Maturana 1992) and the idea of a conserved ‘autopoiesis’, a systematic medium (space) in which all recursive dynamics of reciprocal interactions occur to sustain the survival of life, processes and systems, and where technology can be conceived as a powerful instrument/medium to expand our knowledge about structural and sensitive coherences within living and non-living systems; and, Jorge de Albuquerque Vieira’s (2006; 2009) approach to art as a type of knowledge related to any process that guarantees the permanence or survival of a system based on three major characteristics for the survival of an open system – sensitivity (to operate information flows), memory (to transfer and retain information), and capability (to elaborate or prepare information according to its needs).
Technoetic syncretic environments
Authors: Fraga Tania 
Published: August 2015

Abstract
This article presents and reflects upon artistic artworks at the intersection of virtual and physical computer systems with wet (biological) systems, in reference to Roy Ascott’s ‘moist theory’. It is divided into two sections. The first section offers contextualization by pointing to Darcy Ribeiro’s considerations of differentiations among Brazilians, thus leading to an expectation of miscegenation that assimilates and incorporates races and beliefs in a syncretic way. To this background is added a theoretical framework based on semiotics entwined with mathematics and physics from a set of authors. Both aspects are intertwined with visceral sensations and feelings which emerged from immersible field researches. Glimpses of the 1997 Xingu expedition are introduced as an example of such immersible field research to unveil aspects related with moist theory.
The second section presents four case studies that illustrate all of the concepts previously mentioned. Here, syncretism is understood as a field for events that engender the artworks. These artworks are created as metaphorical journeys aimed at expressing potential shamantic experiences and configured as a set of symbiotic systems. Two of these artworks explore neural connections; their research involves computer devices that allow human interferences in the behaviours of autonomous agents in virtual reality simulations. The resultant systems are artificially alive organisms in flux with the rhythms of the autonomous programmed processes; these change each time they run within the computer, allowing the user to symbiotically interfere in the algorithmic nature of artificial ‘seeds’. These poetic realms are metaphors of the flow of life itself. Summing up, they are technoetic artworks that could only arise from the Brazilian melting pot of cultural, racial and theoretical mixtures.
The world in my body, the ‘other’ in my soul: Living at risk in a moistmedia art ecology
Authors: Almeida Cristina Miranda de 
Published: August 2015

Abstract
The main notion of this article is that the blurring of the limits between offline and online dimensions of knowledge and experience, in addition to the manipulation of genes, neurons, atoms and bits, is dissolving the distinction between subjectivism (i.e. idealism) and materialism (i.e. objectivism and realism). As a consequence, in the moistmedia (from Ascott) ecology in which we are increasingly immersed, a radical kind of experience of matter, time, space and self is emerging. In this form of experience, the blending of subjectivist and materialist approaches help in overcoming the classical Cartesian polarity: we feel part of an extended reality, and we feel this extended reality in ourselves by combining bodies, points of view and multiple senses with digital layers of everything.
The article proposes these research questions: Which are the main factors that shape the change toward a moistmedia ecology resulting from the impact of the manipulation of genes, neurons, bits and atoms? Which transformation is being shaped in relation to the previous model of experience? What are the features of the new forms of materiality, sensitivity and action? How artists are putting themselves at risk in the moistmedia ecology? The hypothesis is that a hybrid kind of interval is opening between different layers of reality: analogue versus digital; nature versus culture; here versus there; past versus future; I versus others; and human versus non-human. In this recombination process, a third dimension of reality – that I call ‘radical reality’ – emerges in the moistmedia ecology. This article will analyse the radical experience (Wilson) in moistmedia environments by crossing the five dimensions (matter, space, time, identity and action) with the practices of manipulation of genes, atoms and bits using examples from art and design. This crossing shows the basic dimensions and sub-dimensions of the ‘Model of Radical Experience’ to reveal the nature of this third dimension between subjectivism and materialism, which is explored by artists who put themselves at risk in the turbulent zone between the physical and the digital.

A new insight in desiccation tolerance and cryopreservation of mazzard cherry (Prunus avium L.) seeds
Authors: Michalak Marcin , Plitta-Michalak Beata P. , Chmielarz Paweł 
Published: August 2015

Abstract
A variable response of Prunus avium L. seeds
to desiccation and storage in liquid nitrogen (LN) has
been reported in the literature. The majority of these
experiments were conducted on initially dried seeds.
The desiccation and LN exposure tolerance of fresh P.
avium seeds is unknown. In the present study, fresh seeds
were used to determine seed response to desiccation and
cryopreservation. Desiccation of seeds from a moisture
content (MC) of 19.7-20.2% to 10.1-10.9% or 07.6-8.5%
reduced seedling emergence from approximately 73 to 19
and 16% for first provenance; and from approximately 89
to 10-12% for second provenance of seeds. After exposure
to LN, seeds had the highest seedling emergence when
seed MC was the highest (19.7 and 20.2%, respectively)
prior to cryostorage. Results indicated that P. avium seeds
should be classified as intermediate. For cryopreservation
in seed banks, we recommend that seeds be dried directly
after extraction from fruits in the range of 16.8-20.2% of
MC (0.21-0.25 g·g–1 of WC) and directly immersed in LN in
tightly closed cryovials.
First record ofNeosiphonia echinata(Rhodomelaceae, Rhodophyta) in the South Pacific: an introduced species in Southeast Asia
Authors: Bustamante Danilo Edson , Won Boo Yeon , Cho Tae Oh 
Published: August 2015

AbstractNeosiphonia echinata,a well-known western Atlantic species, is here reported for the first time from Indonesia and this extends its distribution into Southeast Asia.Neosiphonia echinatawas collected from Sulawesi, Indonesia as an epiphyte onKappaphycus alvareziiand growing on ropes in a culture farm. We also collected this species from Florida, USA, and then compared their morphology and molecular data.Neosiphonia echinatais identified by having erect main filaments arising from prostrate filaments, numerous rhizoids cutting off from the proximal end of pericentral cells by a cross wall, four pericentral cells throughout the thallus, ecorticate axes, very long and abundant trichoblasts more than twice forked, abundant adventitious laterals, procarps with four-celled carpogonial branches, and a spiral arrangement of tetrasporangia. Our phylogenetic analyses ofrbcL andcox1 indicate thatN. echinatafound in Indonesia was very closely related to material from the Western Atlantic Ocean.Neosiphonia echinatamay be added as an introduced species to the Indonesian marine flora. The shipping routes western Atlantic-Mediterranean-Indonesia and western Atlantic-Pacific Ocean-Indonesia might be considered as possible pathways of introduction as a consequence of ballast water and hull fouling.
Geo-spatial modelling with unbalanced data:modelling the spatial pattern of human activityduring the Stone Age
Authors: Jasiewicz Jarosław , Sobkowiak-Tabaka Iwona 
Published: August 2015

Abstract
With the increasing availability of data, geoscienceprovides many methods to model the spatial extentof various phenomena.Acquiring representative, highquality data is the most important criterion to assess thevalue of any spatial analysis, however, there are many situationsin which these criteria cannot be fulfilled. Archiveddata, collected in the past, for which analysis cannot berepeated or supplemented is a very common informationsource. Archaeological data collected at a regional extentduring years of field work and superficial observations arean additional example. Such data rarely provide representativesamples and are usually imbalanced; only very fewexamples contain useful data, while many examples remainwithout any archaeological traces. In spite of theselimitations archaeological information presented in theform of maps can be a useful and helpful tool to analysethe spatial patterns of some phenomena and, from a morepractical point of view, a tool to predict the location ofundiscovered occurrences. The primary goal of this paperis to present a methodology for modelling spatial patternsbased on imbalanced categorical data which do not fulfilthe criteria of spatial representation and incorporatesuncertainty in its decision process. This concept will bediscussed using a collection of Stone Age sites and set ofenvironmental variables from the postglacial lowlands inWestern Poland. We will propose a machine-learning systemwhich adopts CART through bootstrap simulation toincorporate uncertainty into the spatial model and utilisethat uncertainty in the decision-making process. Finally,we will describe the relationships between the model andenvironmental variables and present our results in cartographicform using the principles of decision-tree cartography.
“What Is Royalty Without a Voice?” The Performance of Power in The King’s Speech
Authors: Logaldo Mara 
Published: August 2015

Abstract
The core subject of The King’s Speech (Tom Hooper, 2010) is the relation between voice and power. In the first place, we have the speech impediment of the Duke of York (the future George VI) and his subsequent inability to deliver effectual messages to the nation in a particularly dramatic phase in history. This failure highlights, by contrast, the identification of monarchy with voice. The film actually shows how the performative power of speech became crucial after the invention of the wireless. The BBC, as George V stated on his death bed, had turned kings into actors: elocution could either make or unmake them. Yet, these are only some facets of the complex dynamics by which language and power are interrelated in the film. Another important issue is the form of verbal exchange between doctor and patient, which enacts a wavering between two kinds of authority, the one possessed by right (legitimate power) and the one acquired by study and experience (expert power). Emphasis is also placed on standard English as the language traditionally associated with higher education, political supremacy and prestige. The importance given to Received Pronunciation and the contempt shown towards other language variants proves how deeply embedded in language power is. Though amiably, even the ironic remarks on conversational rules made by Elizabeth, the future Queen Mother, finally confirm the status quo, putting things and people back into place on the social scale. This is also, ultimately, the policy of the BBC, the institution that has been invested with the task of preserving, at the same time, British national identity and the purity of the English language.
War in Words: The Tricycle Theatre’s Re-voicing of the Bloody Sunday Inquiry
Authors: Soncini Sara 
Published: August 2015

Abstract
The tribunal plays produced at the Tricycle theatre in Kilburn, North London have come to represent under many respects the hallmark of the new spate of documentary work on the British stage, often designated as “verbatim drama” in contemporary critical parlance. Expressly envisaged as theatrical interventions into the public sphere, these dramatizations of official public inquiries turn theatrical space into legal space, grounding their claims to veracity in the exact reproduction of the actually spoken. While crucial to their ontological authority, the self-imposed orthodoxy whereby the playwright is the mere editor of words recorded in inquiry transcripts has been put under considerable strain by the very topic that has played a central role in triggering and shaping the format, that of contemporary conflict. A considerable share of recent verbatim work deals with the war on terror, a war increasingly fought outside legal jurisdiction and hence a subject that has thrown into sharp relief the epistemological limits of a form of drama that is entirely dependent on the existence and availability of legal records. This essay looks at the strategies of “re-voicing” whereby Richard Norton-Taylor negotiates the strictures of the code in his tribunal play Bloody Sunday: Scenes from the Saville Inquiry (2005). By turning the spotlight on testimony as a conflicted practice, Norton-Taylor’s editorial perspective provides a scorching critique of the long-overdue official review of the tragic events in Derry on 30 January 1972, and at the same time manages to indirectly address some highly topical issues of legitimacy and legality raised by the intervention in Iraq.
On the Complementarity between Law and Social Norms
Authors: Tsuneki Atsushi , Zasu Yoshinobu 
Published: August 2015

AbstractThis article aims to clarify the relationship between the law and social norms and examine how they interact – whether the law completely replaces, or coexists with, the pre-existing social norms. We model a close-knit society consisting of injurers and victims, assuming that both the law and social norms maximize social welfare and that the costs of enforcing legal penalties are greater than those of enforcing social norms. We find that social norms completely replace the law, even in a non-cooperative Nash equilibrium; we then develop exceptions to this result. In particular, when community sanctions for violating social norms are calibrated without consideration of its marginal social benefit due to a reduction in law enforcement cost, our model can have multiple equilibria, including cases in which legal sanctions persist even in the long run, in spite of their inefficiently high enforcement costs. However, we also show that this possibility of an inefficient non-cooperative equilibrium can be eliminated if the government behaves as a Stackelberg leader for the formation of social norms.
Targeting the vasculature
to improve neural
progenitor transplant
survival
Authors: Hill Justin , Cave John 
Published: August 2015

Abstract
Neural progenitor transplantation is a promising therapeutic option for several neurological diseases and
injuries. In nearly all human clinical trials and animal models that have tested this strategy, the low survival rate
of progenitors after engraftment remains a significant challenge to overcome. Developing methods to improve
the survival rate will reduce the number of cells required for transplant and will likely enhance functional
improvements produced by the procedure. Here we briefly review the close relationship between the blood
vasculature and neural progenitors in both the embryo and adult nervous system. We also discuss previous
studies that have explored the role of the vasculature and hypoxic pre-conditioning in neural transplants.
From these studies, we suggest that hypoxic pre-conditioning of a progenitor pool containing both neural and
endothelial cells will improve engrafted transplanted neuronal survival rates.
Nonlocal Symmetry, CRE Solvability and Exact Interaction Solutions of the Asymmetric Nizhnik–Novikov–Veselov System
Authors: Hu Xiaorui , Chen Yong 
Published: August 2015

Abstract
Applying the truncated Painlevé expansion to the (2+1)-dimensional asymmetric Nizhnik–Novikov–Veselov (ANNV) system, some Bäcklund transformations (BTs) including auto BT and non-auto BT are obtained. The auto BT leads to a nonlocal symmetry which corresponds to the residual of the truncated Painlevé expansion and the related nonlocal symmetry group is presented with the help of the localization procedure. Further, it is shown that the ANNV system has a consistent Riccati expansion (CRE). Stemming from the consistent tan-function expansion (CTE), which is a special form of CRE, some complex interaction solutions between soliton and arbitrary other seed waves of the ANNV system are readily constructed, such as bight-dark soliton solution, dark-dark soliton solution, soliton-cnoidal interaction solutions, solitoff solutions and so on.
ESCRTs are everywhere
Authors: Hurley James H 
Published: August 2015

AbstractThe ESCRT proteins are an ancient system that buds membranes and severs membrane necks from their inner face. Three “classical” functions of the ESCRTs have dominated research into these proteins since their discovery in 2001: the biogenesis of multivesicular bodies in endolysosomal sorting; the budding of HIV‐1 and other viruses from the plasma membrane of infected cells; and the membrane abscission step in cytokinesis. The past few years have seen an explosion of novel functions: the biogenesis of microvesicles and exosomes; plasma membrane wound repair; neuron pruning; extraction of defective nuclear pore complexes; nuclear envelope reformation; plus‐stranded RNA virus replication compartment formation; and micro‐ and macroautophagy. Most, and perhaps all, of the functions involve the conserved membrane‐neck‐directed activities of the ESCRTs, revealing a remarkably widespread role for this machinery through a broad swath of cell biology.
A Coalescent Model for a Sweep of a Unique Standing Variant
Authors: Berg Jeremy J , Coop Graham 
Published: August 2015

AbstractThe use of genetic polymorphism data to understand the dynamics of adaptation and identify the loci that are involved has become a major pursuit of modern evolutionary genetics. In addition to the classical “hard sweep” hitchhiking model, recent research has drawn attention to the fact that the dynamics of adaptation can play out in a variety of different ways and that the specific signatures left behind in population genetic data may depend somewhat strongly on these dynamics. One particular model for which a large number of empirical examples are already known is that in which a single derived mutation arises and drifts to some low frequency before an environmental change causes the allele to become beneficial and sweeps to fixation. Here, we pursue an analytical investigation of this model, bolstered and extended via simulation study. We use coalescent theory to develop an analytical approximation for the effect of a sweep from standing variation on the genealogy at the locus of the selected allele and sites tightly linked to it. We show that the distribution of haplotypes that the selected allele is present on at the time of the environmental change can be approximated by considering recombinant haplotypes as alleles in the infinite-alleles model. We show that this approximation can be leveraged to make accurate predictions regarding patterns of genetic polymorphism following such a sweep. We then use simulations to highlight which sources of haplotypic information are likely to be most useful in distinguishing this model from neutrality, as well as from other sweep models, such as the classic hard sweep and multiple-mutation soft sweeps. We find that in general, adaptation from a unique standing variant will likely be difficult to detect on the basis of genetic polymorphism data from a single population time point alone, and when it can be detected, it will be difficult to distinguish from other varieties of selective sweeps. Samples from multiple populations and/or time points have the potential to ease this difficulty.
Inference Under a Wright-Fisher Model Using an Accurate Beta Approximation
Authors: Tataru Paula , Bataillon Thomas , Hobolth Asger 
Published: August 2015

Abstract
The large amount and high quality of genomic data available today enable, in principle, accurate inference of evolutionary histories of observed populations. The Wright-Fisher model is one of the most widely used models for this purpose. It describes the stochastic behavior in time of allele frequencies and the influence of evolutionary pressures, such as mutation and selection. Despite its simple mathematical formulation, exact results for the distribution of allele frequency (DAF) as a function of time are not available in closed analytical form. Existing approximations build on the computationally intensive diffusion limit or rely on matching moments of the DAF. One of the moment-based approximations relies on the beta distribution, which can accurately describe the DAF when the allele frequency is not close to the boundaries (0 and 1). Nonetheless, under a Wright-Fisher model, the probability of being on the boundary can be positive, corresponding to the allele being either lost or fixed. Here we introduce the beta with spikes, an extension of the beta approximation that explicitly models the loss and fixation probabilities as two spikes at the boundaries. We show that the addition of spikes greatly improves the quality of the approximation. We additionally illustrate, using both simulated and real data, how the beta with spikes can be used for inference of divergence times between populations with comparable performance to an existing state-of-the-art method.
