Vertical Melting of a Stack of Membranes

A stack of tensionless membranes with nonlinear curvature energy and vertical harmonic interaction is studied. At low temperatures, the system forms a lamellar phase. At a critical temperature, the stack disorders vertically in a melting-like transition.Comment: 8 pages, 2 figure

Quantum Key Distribution using Continuous-variable non-Gaussian States

In this work we present a quantum key distribution protocol using continuous-variable non-Gaussian states, homodyne detection and post-selection. The employed signal states are the Photon Added then Subtracted Coherent States (PASCS) in which one photon is added and subsequently one photon is subtracted. We analyze the performance of our protocol, compared to a coherent state based protocol, for two different attacks that could be carried out by the eavesdropper (Eve). We calculate the secret key rate transmission in a lossy line for a superior channel (beam-splitter) attack, and we show that we may increase the secret key generation rate by using the non-Gaussian PASCS rather than coherent states. We also consider the simultaneous quadrature measurement (intercept-resend) attack and we show that the efficiency of Eve's attack is substantially reduced if PASCS are used as signal states.Comment: We have included an analysis of the simultaneous quadrature measurement attack plus 2 figures; we have also clarified some point

(Un)doing home: exploring home-making and identity – an example of a project in a London higher education classroom

In this article we discuss the lived, embodied experience of home-making in relation to identity and belonging through the example of a service-learning project conducted during the Covid-19 pandemic in a higher education setting in London, UK. We also explore the notion of belonging-not-belonging as a cultural, material and embodied construct, inspired by critical pedagogy. We draw on posthumanism, new materialism, intercultural studies, (auto-)ethnography and creative practice research as possible lines of flight in deconstructing the dichotomy between home and a ‘foreign’ territory-other-than-home that sits at the core of intercultural discourses. We present this project as a possible alternative discourse to (un)do more traditional considerations of home-making as a much more complex construct; in the encounter with new territories, humans and other-than-human artefacts, objects, machines and landscapes, we argue that home-making is a continuous, never-finished process that moves the learner and their teachers continuously. We aim to bring to the forefront new emerging considerations of intercultural studies at the intersection with interdisciplinary, cross-disciplinary and cross-institutional discourses, breaking away from a more traditional and neoliberal view about what belonging means within the context of higher education

Plasma Exchange in Clinical Practice

Plasma exchange (PEX) is a treatment method with increasing range of indications. However, due to the small number of randomized trials, its effectiveness is still under debate in certain conditions. The aim of our chapter is to present the major principles of PEX, discuss safety issues and reveal current data for treatment effectiveness of the method. Novel indications for PEX will also be discussed

Vitamin D and Renal Disease

The metabolism of vitamin D (VD) is severely impaired in chronic kidney disease (CKD). Uremia is not only associated with the reduction of its active form 1,25-dihydroxyvitamin D but also in the reduction of all VD metabolites. CKD-associated abnormalities in VD are part of the CKD-related mineral-bone disease. However, VD has beneficial effect on the kidneys due to its pleiotropic effects, namely, antiproteinuric effect and renin-angiotensin-aldosterone system suppression, thus making the relationship between VD and the kidney even more complicated. The aim of our chapter is to reveal the changes in vitamin D axis in CKD, to outline the possible beneficial effects of vitamin D in renal patients, including end-stage renal patients and kidney transplant recipients, and to address the current opinions concerning treatment with cholecalciferol, calcitriol, and vitamin D analogs

Decrumpling membranes by quantum effects

The phase diagram of an incompressible fluid membrane subject to quantum and thermal fluctuations is calculated exactly in a large number of dimensions of configuration space. At zero temperature, a crumpling transition is found at a critical bending rigidity $1/\alpha_{\rm c}$. For membranes of fixed lateral size, a crumpling transition occurs at nonzero temperatures in an auxiliary mean field approximation. As the lateral size L of the membrane becomes large, the flat regime shrinks with $1/\ln L$.Comment: 9 pages, 4 figure

De Novo Assembly Of Candida Sojae And Candida Boidinii Genomes, Unexplored Xylose-consuming Yeasts With Potential For Renewable Biochemical Production

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Candida boidinii and Candida sojae yeasts were isolated from energy cane bagasse and plague-insects. Both have fast xylose uptake rate and produce great amounts of xylitol, which are interesting features for food and 2G ethanol industries. Because they lack published genomes, we have sequenced and assembled them, offering new possibilities for gene prospection. © 2016 Borelli et al.41CAPES, Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorCNPq, Conselho Nacional de Desenvolvimento Científico e TecnológicoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Conceptual analysis: A Social neuroscience approach to interpersonal interaction in the context of disruption and disorganization of attachment (NAMDA)

Humans are strongly dependent upon social resources for allostasis and emotion regulation. This applies especially to early childhood because humans-as an altricial species-have a prolonged period of dependency on support and input from caregivers who typically act as sources of co-regulation. Accordingly, attachment theory proposes that the history and quality of early interactions with primary caregivers shape children's internal working models of attachment. In turn, these attachment models guide behavior, initially with the set goal of maintaining proximity to caregivers but eventually paving the way to more generalized mental representations of self and others. Mounting evidence in non-clinical populations suggests that these mental representations coincide with differential patterns of neural structure, function, and connectivity in a range of brain regions previously associated with emotional and cognitive capacities. What is currently lacking, however, is an evidence-based account of how early adverse attachment-related experiences and/or the emergence of attachment disorganization impact the developing brain. While work on early childhood adversities offers important insights, we propose that how these events become biologically embedded crucially hinges on the context of the child-caregiver attachment relationships in which the events take place. Our selective review distinguishes between direct social neuroscience research on disorganized attachment and indirect maltreatment-related research, converging on aberrant functioning in neurobiological systems subserving aversion, approach, emotion regulation, and mental state processing in the wake of severe attachment disruption. To account for heterogeneity of findings, we propose two distinct neurobiological phenotypes characterized by hyper- and hypo-arousal primarily deriving from the caregiver serving either as a threatening or as an insufficient source of co-regulation, respectively
