Acoustic Emission Activity for Characterizing Fracture of Marble under Bending

The present paper occupies with the acoustic emission (AE) monitoring of fracture of marble. The specimens belong to two different material types and were tested in three-point bending after being ultrasonically interrogated. Consequently, they were repaired by means of suitable epoxy agent and mechanically re-loaded. Apart from the well-known correlation of pulse velocity to strength, which holds for the materials of this study as well, AE provides some unique insight in the fracture of the media. Parameters like the frequency content of the waveforms, and their duration among others show a transition in relation to the load. According to their strength class, the specimens exhibit distinct AE characteristics even at low load, enabling to judge their final strength class after having sustained just a small percentage of their ultimate capacity. More importantly, the AE activity during reloading indicates the quality of repair; specimens with good restoration of strength, exhibited similar AE activity to the intact specimens, while specimens with lower repaired capacity exhibited random behavior. This work discusses the passive monitoring of marble fracture and shows that AE parameters that have been used to successfully characterize cementitious materials, provide good results in monolithic materials like marble as well. It is suggested that AE monitoring during a proof loading can provide good information on the potential strength class, which is especially useful for repaired specimens, where the pulse velocity cannot be easily used.
The Spectro-Contextual Encoding and Retrieval Theory of Episodic Memory

The spectral fingerprint hypothesis, which posits that different frequencies of oscillations underlie different cognitive operations, provides one account for how interactions between brain regions support perceptual and attentive processes (Siegel etal., 2012). Here, we explore and extend this idea to the domain of human episodic memory encoding and retrieval. Incorporating findings from the synaptic to cognitive levels of organization, we argue that spectrally precise cross-frequency coupling and phase-synchronization promote the formation of hippocampal-neocortical cell assemblies that form the basis for episodic memory. We suggest that both cell assembly firing patterns as well as the global pattern of brain oscillatory activity within hippocampal-neocortical networks represents the contents of a particular memory. Drawing upon the ideas of context reinstatement and multiple trace theory, we argue that memory retrieval is driven by internal and/or external factors which recreate these frequency-specific oscillatory patterns which occur during episodic encoding. These ideas are synthesized into a novel model of episodic memory (the spectro-contextual encoding and retrieval theory, or “SCERT”) that provides several testable predictions for future research.
Relational Goods, Sociability, and Happiness

The role of sociability and relational goods has generally been neglected in the formulation of standard economics textbook preferences. Our findings show that relational goods have significant and positive effects on self declared life satisfaction, net of the impact of other concurring factors. We also document that such effects persist when the equally significant inverse causality nexus is taken into account. This implies that a more intense relational life enhances life satisfaction and, at the same time, happier people have a more lively social life. Finally, we show that gender, age and education matter by showing that the effects of sociability on happiness are stronger for women, older and less educated individuals.
A statistical model for tensor PCA

We consider the Principal Component Analysis problem for large tensors of arbitrary order $k$ under a single-spike (or rank-one plus noise) model. On the one hand, we use information theory, and recent results in probability theory, to establish necessary and sufficient conditions under which the principal component can be estimated using unbounded computational resources. It turns out that this is possible as soon as the signal-to-noise ratio $\beta$ becomes larger than $C\sqrt{k\log k}$ (and in particular $\beta$ can remain bounded as the problem dimensions increase). On the other hand, we analyze several polynomial-time estimation algorithms, based on tensor unfolding, power iteration and message passing ideas from graphical models. We show that, unless the signal-to-noise ratio diverges in the system dimensions, none of these approaches succeeds. This is possibly related to a fundamental limitation of computationally tractable estimators for this problem. We discuss various initializations for tensor power iteration, and show that a tractable initialization based on the spectrum of the matricized tensor outperforms significantly baseline methods, statistically and computationally. Finally, we consider the case in which additional side information is available about the unknown signal. We characterize the amount of side information that allows the iterative algorithms to converge to a good estimate.
Transcranial direct current stimulation in post-stroke dysphagia: a systematic review of randomized controlled trials

Introduction: The aim of this research was to systematically review all the randomized controlled trials that have evaluated the effect of transcranial direct current stimulation (tDCS) on post-stroke dysphagia. Methods: Three electronic databases were searched for relevant articles that were uploaded from their inception to March 2015: PubMed, Cochrane Library (Cochrane Central Register of Controlled Trials), and Scopus. All data was that was related to the location of the cerebrovascular accident (CVA), the parameters of tDCS, post-stroke time to commencement of tDCS, the stimulated hemisphere, stimulation dose, any outcome measurements, and follow-up duration were extracted and assessed. Finally, a number of observations were generated through a qualitative synthesis of the extracted data.Result: Three eligible randomized controlled trials were included in the systematic review. All three trials reported that, in comparison to a placebo, tDCS had a statistically significant effect on post-stroke dysphagia.Discussion: The results of our systematic review suggest that tDCS may represent a promising novel treatment for post-stroke dysphagia. However, to date, little is known about the optimal parameters of tDCS for relieving post-stroke dysphagia. Further studies are warranted to refine this promising intervention by exploring the optimal parameters of tDCS.Conclusion: Since brainstem swallowing centers have bilateral cortical innervations, measures that enhance cortical input and sensorimotor control of brainstem swallowing may facilitate recovery from dysphagia.
Near-optimal critical sink routing tree constructions

We present critical-sink routing tree (CSRT) constructions which exploit available critical-path information to yield high-performance routing trees. Our CS-Steiner and "global slack removal" algorithms together modify traditional Steiner tree constructions to optimize signal delay at identified critical sinks. We further propose an iterative Elmore routing tree (ERT) construction which optimizes Elmore delay directly, as opposed to heuristically abstracting linear or Elmore delay as in previous approaches. Extensive timing simulations on industry IC and MCM interconnect parameters show that our methods yield trees that significantly improve (by averages of up to 67%) over minimum Steiner routings in terms of delays to identified critical sinks. ERTs also serve as generic high-performance routing trees when no critical sink is specified: for 8-sink nets in standard IC (MCM) technology, we improve average sink delay by 19% (62%) and maximum sink delay by 22% (52%) over the minimum Steiner routing. These approaches provide simple, basic advances over existing performance-driven routing tree constructions. Our results are complemented by a detailed analysis of the accuracy and fidelity of the Elmore delay approximation; we also exactly assess the suboptimality of our heuristic tree constructions. In achieving the latter result, we develop a new characterization of Elmore-optimal routing trees, as well as a decomposition theorem for optimal Steiner trees, which are of independent interest.

A systematic review of medication non-adherence in persons with dementia or cognitive impairment

Background Adherence to medication is vital for disease management while simultaneously reducing healthcare expenditure. Older persons with cognitive impairment (CI) are at risk for non-adherence as cognitive processes are needed to manage medications. This systematic review focuses on the relationship between medication non-adherence and specific cognitive domains in persons with CI, and explores determinants of medication non-adherence. When available, relationships and factors are compared with cognitively intact populations. Methods A seven database systematic search of studies published between 1 January 1949–31 December 2015 examining medication non-adherence in community dwelling persons with CI or dementia was conducted. Articles reporting medication non-adherence in people with CI or dementia in the community, with or without caregiver supports were eligible for inclusion. Papers reporting adherence to treatments in cognitively intact populations, populations from hospital or institutional settings, for non-prescribed medication or those describing dementia as a factor predicting medication non-adherence were excluded. Data on study and population characteristics, research design, data sources and analysis, specific cognitive domains, non-adherence prevalence, measurement of adherence, salient findings, factors associated with adherence and strategies to improve medication adherence were extracted. Study limitations included inconsistencies between data sources and definitions, resulting in a loss of fidelity in the value and comprehensiveness of data, as well as exclusion of non-pharmacological treatments and regimens. Findings Fifteen studies met inclusion criteria. Adherence among CI subjects ranged from 10.7%-38% with better rates of adherence in non-CI individuals. Medication non-adherence definitions varied considerably. New-learning, memory and executive functioning were associated with improved adherence and formed the focus of most studies. Multiple factors were identified as modulators of non-adherence. Conclusion This review highlights a gap in knowledge on how specific cognitive domains contribute to medication non-adherence amongst CI populations, and demonstrates the current focus is limited to two domains: memory and executive functioning.
Estimation of a k-monotone density, part 1: characterizations consistency, and minimax lower bounds

Shape constrained densities are encountered in many nonparametric estimation problems. The classes of monotone or convex (and monotone) densities can be viewed as special cases of the classes of k-monotone densities. A density g is said to be k-monotone if its successive derivatives up to order k-2 are alternately negative or positive, with the k-2 derivative convex (or concave) according as k is even (or odd) respectively. g is simply nonincreasing if k=1. These classes of shape constrained densities bridge the gap between the classes of monotone (1-monotone) and convex decreasing (2-monotone) densities for which asymptotic results are known, and the class of completely monotone densities with k infinite. In this series of four papers we consider both (nonparametric) Maximum Likelihood estimators and Least Squares estimators of a k-monotone density. In this first part (part 1), we prove existence of the estimators and give characterizations. We also establish consistency properties, and show that the estimators are splines of order k (degree k-1) with simple knots. We further provide asymptotic minimax risk lower bounds for estimating a k-monotone density g_0 (x_0) and its derivatives g_0^{(j)}(x_0), for j=1, . , k-1, at a fixed point x_0 under the assumption that the k-th derivative of g_0 at x_0 is non-zero.
Searching for cool core clusters at high redshift

Aims. We investigate the detection of Cool Cores (CCs) in the distant galaxy cluster population with the purpose of measuring the CC fraction out to redshift 0.7 ≤ z 0.7, and should also be related to the shorter age of distant clusters, implying less time to develop a cool core.
Should Public Displays be Interactive? Evaluating the Impact of Interactivity on Audience Engagement

This paper describes a comparative case study that aims to uncover the quantifiable differences between non-interactive and interactive public displays in the urban environment. The study involved a large temporary interactive public display on a central city square showing a selection of custom-made content. We have evaluated the effect on passers-by and spectators in two conditions: 1) non-interactive (2102 passers-by, 228 viewers), by showing a content loop, and 2) interactive (1676 passers-by, 257 viewers), by adding physical pushbuttons for content selection and gaming. We discuss the influence of non-interactive and interactive public displays on: 1) attracting attention, 2) engaging people, 3) improving social dynamics within and among groups of viewers, and 4) catering for the suitable time of day. Based on our observations, we provide quantitative support for the hypothesis that interactive displays are more successful than non-interactive displays to engage viewers, and to make city centers more lively and attractive.
Regenerative Therapies Using Cell Sheet-Based Tissue Engineering for Cardiac Disease

At present, cardiac diseases are a major cause of morbidity and mortality in the world. Recently, a cell-based regenerative medicine has appeared as one of the most potential and promising therapies for improving cardiac diseases. As a new generational cell-based regenerative therapy, tissue engineering is focused. Our laboratory has originally developed cell sheet-based scaffold-free tissue engineering. Three-dimensional myocardial tissue fabricated by stacking cardiomyocyte sheets, which are tightly interconnected to each other through gap junctions, beats simultaneously and macroscopically and shows the characteristic structures of native heart tissue. Cell sheet-based therapy cures the damaged heart function of animal models and is clinically applied. Cell sheet-based tissue engineering has a promising and enormous potential in myocardial tissue regenerative medicine and will cure many patients suffering from severe cardiac disease. This paper summarizes cell sheet-based tissue engineering and its satisfactory therapeutic effects on cardiac disease.
Pathogenicity of Salmonella enterica in Caenorhabditis elegans Relies on Disseminated Oxidative Stress in the Infected Host

Feeding Caenorhabditis elegans with Salmonella enterica serovar Typhimurium significantly shortens the lifespan of the nematode. S. Typhimurium-infected C. elegans, stained with 2′,7′-dichlorodihydrofluorescein diacetate which fluoresces upon exposure to reactive oxygen species, revealed intestinal luminal staining that along with the time of infection progressed to a strong staining in the hypodermal tissues of the nematode. Still, we could not detect invasion beyond the nematode's intestinal epithelium at any stage of the infection. A similar dispersion of oxidative response was also noted in nematodes infected with S. Dublin, but not with non-pathogenic Escherichia coli or the defined pathogen Burkholderia thailandensis. Addition of catalase or the reductant ascorbic acid significantly restored the lifespan of S. Typhimurium-infected nematodes. Mutational inactivation of the bacterial thioredoxin 1 resulted in total ablation of the hypodermal oxidative response to infection, and in a strong attenuation of virulence. Virulence of the thioredoxin 1 mutant was restored by trans-complementation with redox-active variants of thioredoxin 1 or, surprisingly, by exposing the thioredoxin 1 mutant to sublethal concentrations of the disulphide catalyst copper chloride prior to infection. In summary, our observations define a new aspect in virulence of S. enterica that apparently does not involve the classical invasive or intracellular phenotype of the pathogen, but that depends on the ability to provoke overwhelming systemic oxidative stress in the host through the redox activity of bacterial thioredoxin 1.
Democratization, Decentralization and the Distribution of Local Public Goods in a Poor Rural Economy

In this paper we exploit a unique panel data set describing village governance, public goods allocations, and economic circumstances in India over the past twenty years to examine the consequences of democratization and fiscal decentralization within a model that highlights landownership-based interest groups. We first construct a simple model of two-party representative democracy with probabilistic voting in which local governments must choose to allocate public resources among three different goods representing the principal local public goods in Indian villages: roads, which primarily benefit the poor by raising wages; irrigation facilities, which differentially benefit landowners; and schools which have neutral effects. We embed the voting model in a general-equilibrium model of the rural economy in order to capture the general-equilibrium effects of changes in the landless share on the economic returns to the public goods. The model yields predictions about how the landless share affects allocations of the specific public goods under democracy relative to an alternative regime in which the local elite have a disproportionate effect on outcomes relative to that dictated by democracy. The model also has implications for the effects of ceding revenue-generating authority to the local governing body that permit an assessment of the differential burden of taxation on the rich and poor. Based on specifications consistent with the model, we then find evidence consistent with the two-party model of democracy in which increasing the population weight of the poor induces public resource allocations that increase the welfare of the poor. However, we also find that local taxes, where they are permitted, are regressive - the (landless) poor pay a higher tax rate on consumption than do the rich. Finally, we assess the growth implications of local democratization. Our evidence is consistent with almost-perfect substitution of public and private irrigation investment. Our findings thus suggest that the shift in the portfolio of local public goods associated with local democratization in part represents a transformation of a local welfare program from one that serves the rich to one that increases the welfare of the poor with possibly a net gain in total output.
Committed to learn: student engagement and care in higher education

ABSTRACT Efforts to evaluate and improve student engagement have been pervasive in higher education over recent years. Critics argue, however, that troubling affinities are evident between student engagement efforts and a neoliberal agenda which emphasises accountability through performativity. Neoliberalism manifests in policies that focus on the economic benefit to individuals of higher education, rather than the broader social or intrinsic benefits. In this conceptual article, we draw on the work of Martin Heidegger and Nel Noddings in arguing that efforts aimed at promoting engagement and commitment to learn by students should include developing a capacity to care about others and things. Through the lens of care, our aim is to extend current notions of what engagement of students in their learning might look like. Challenging and supporting students entail encouraging them to take a stand on what they are learning and who they are becoming. This enriched conceptualisation has the potential to re-orient student engagement away from a narrow neoliberal agenda, while enabling students to realise the full benefits a higher education can provide.
The rise and fall of multinational enterprises in Vietnam : survival analysis using census data during 2000-2011 March 14 , 2014

[Key words] Foreign direct investment; Multinational enterprises; Survival; Ownership; Government performance; Vietnam [JEL Codes] L24, L25, O02, P27 [Abstract] Using census data from 2000–2011, we examined the survival of multinational enterprises (MNEs) located in Vietnam using Cox hazard models with time–variant covariates. Beside enterprises’ characteristics and performance, we found that the firm characteristics, structure of the ownership and nationalities of the foreign partners are associated with the probability of exiting, which suggests that a joint–venture between a foreign partner and a domestic non–state owned enterprise is more likely to exit than other types of MNEs. Also, a firm with a greater capital share owned by foreign partners was found to survive longer. Furthermore, time cost due to bureaucratic procedures and inspections, among indicators of local government performance, was found to be associated with a greater probability of MNEs exiting.
A Decoupling Approach to the Quantum Capacity

We give a short proof that the coherent information is an achievable rate for the transmission of quantum information through a noisy quantum channel. Our method is to produce random codes by performing a unitarily covariant projective measurement on a typical subspace of a tensor power state. We show that, provided the rank of each measurement operator is sufficiently small, the transmitted data will, with high probability, be decoupled from the channel environment. We also show that our construction leads to random codes whose average input is close to a product state and outline a modification yielding unitarily invariant ensembles of maximally entangled codes.
