Contact, closure and friction behaviour of rough crack concrete surfaces

Concrete-to-concrete friction contributes in many cases to the stability of a structure. In concrete dams, the assessment of safety under the presence of large cracks is combined with the problem of leakage through the same cracks. In other structural members, the possibility of interface shear transfer is explicitly taken into account at the ultimate state. In this paper, the closure and shear behaviour of cracks in concrete structures is investigated by means of a coupled numerical/experimental approach. Dilatancy is considered, and the lacunar fractality of the true contact domains is evidenced.
FIXED POINT AND COMMON FIXED POINT RESULTS FOR EXPANSIVE MAPPINGS IN Gb- CONE METRIC SPACES

Very recently, Manoj Ughade and R D Daheriya [18] introduced the concept of -cone metric and some established some fixed point and common fixed point theorems for self-mappings satisfying various contractive conditions in -cone metric spaces without the assumption of normality. In this paper, we present a fixed point theorem for self-mappings satisfying expansive type condition -cone metric spaces without the assumption of normality. Moreover, some examples are provided to illustrate the usability of the obtained results.
Title Increasing hepatitis C knowledge among homeless adults : Results of a community-based , interdisciplinary intervention Permalink

Homeless adults have high rates of hepatitis C virus infection (HCV) and low levels of HCV knowledge. This study reports results of an interdisciplinary, community-based intervention using stakeholder cooperation, case management, risk factor identification, and modification of dysfunctional psychosocial factors to increase HCV knowledge among homeless adults (N0747). Data are from a randomized quasi-experimental study, with the major goal of evaluating the effectiveness of a Nurse Case Managed Intervention compared to a Standard Intervention, encouraging completion of a three-series hepatitis A/hepatitis B vaccination program.

A significant increase in HCV knowledge resulted regardless of intervention format. Receiving the Nurse Case Managed Intervention predicted greatest gain in HCV knowledge (pG0.000). Successfully engaging key stakeholders, outreach workers, community organizations, and homeless people themselves proved most efficacious in increasing HCV knowledge.
A functional wavelet–kernel approach for time series prediction

Summary. We consider the prediction problem of a time series on a whole time interval in terms of its past. The approach that we adopt is based on functional kernel nonparametric regression estimation techniques where observations are discrete recordings of segments of an underlying stochastic process considered as curves. These curves are assumed to lie within the space of continuous functions, and the discretized time series data set consists of a relatively small, compared with the number of segments, number of measurements made at regular times. We estimate conditional expectations by using appropriate wavelet decompositions of the segmented sample paths. A notion of similarity, based on wavelet decompositions, is used to calibrate the prediction. Asymptotic properties when the number of segments grows to ∞ are investigated under mild conditions, and a nonparametric resampling procedure is used to generate, in a flexible way, valid asymptotic pointwise prediction intervals for the trajectories predicted. We illustrate the usefulness of the proposed functional wavelet–kernel methodology in finite sample situations by means of a simulated example and two real life data sets, and we compare the resulting predictions with those obtained by three other methods in the literature, in particular with a smoothing spline method, with an exponential smoothing procedure and with a seasonal autoregressive integrated moving average model.
Workers’ Health and Establishment Size

I document the relationship between establishment size and various measures of workers' health. Workers at larger establishments are more likely to have chronic health conditions, have had a bed disability day in the last 12 months and be obese. They are also less likely to be smokers. Results for other health measures depend on the specification. My results may help in more effectively targeting workplace wellness programs. The results may also inform the design of better public interventions aimed at reducing occupational injuries. I discuss the relevance of my results for the establishment size-wage premium.
Hepatocellular carcinoma : Eastern and Western experiences Advancement in HCC imaging : diagnosis , staging and treatment efficacy assessments Hepatocellular carcinoma : imaging in assessing treatment efficacy

Imaging studies play a crucial role in the diagnosis and staging of hepatocellular carcinoma (HCC). Yet, assessment of tumor response is another important goal for imaging. The imaging techniques most commonly used for assessing tumor response include computed tomography and magnetic resonance imaging. Imaging modalities and imaging criteria vary according to the treatment (surgical resection and transplantation or nonsurgical treatments such as transarterial chemoembolization, radiofrequency ablation, and molecular targeted therapy). Efficacy of nonsurgical treatments for malignancy is usually evaluated with RECIST criteria. These criteria, based on tumor shrinkage, are often inappropriate in HCCs. The response criteria should take into account tumor necrosis induced by treatment. Today, tumor necrosis is estimated by a disappearance of hypervascularization on contrast-enhanced imaging. New tools such as functional imaging (perfusion imaging, diffusion-weighted MR imaging) could be of major importance. In this article, we present a summary of the most recent information on the role of imaging in assessing treatment efficacy in HCCs.
Evidence for the effectiveness of progressive urban water demand management

Based on panel data from the City of Davis, California, comprising more than 15,000 urban water consumption units and 81 billing periods over 13 years, this study investigates residential water demand and the effectiveness of three structural water conservation measures. The city switched from a uniform to an increasing block pricing scheme, introduced a second tariff block for single-family residential households, and changed the calculation logic for the household sewer rate. An instrumental fixed effects regression analysis results in a price elasticity of -0.19 for residential consumers. The data also suggests that all structural tariff adjustments were effective, even under consideration of the general economic situation. This is the first study which demonstrates the effectiveness of coupling the sewer rate with a proxy for indoor water consumption on a household level.

Studies on separation and properties of lumbrokinase in Pheretima praepinguis

The purpose of this study was to separate lumbrokinase in Pheretima praepinguis and examine its enzymatic properties. With P. praepinguis as material, lumbrokinase was separated with the salting out method. Lumbrokinase activity was measured with casein medium plate method. Effect of pH and temperature on lumbrokinase activity was studied. Results of lumbrokinase separated from P. praepinguis was relatively high. Lumbrokinase activity in neutral or slightly alkaline environment was higher. Lumbrokinase had tolerance ability to high temperature, with highly enzymatic activity under 60°C and wide range of temperature adaptation.
Multisegment rupture in the 11 July 1889 Chilik earthquake (Mw 8.0–8.3), Kazakh Tien Shan, interpreted from remote sensing, field survey, and paleoseismic trenching

The 11 July 1889 Chilik earthquake (Mw 8.0–8.3) forms part of a remarkable sequence of large earthquakes in the late nineteenth and early twentieth centuries in the northern Tien Shan. Despite its importance, the source of the 1889 earthquake remains unknown, though the macroseismic epicenter is sited in the Chilik valley, ~100 km southeast of Almaty, Kazakhstan (~2 million population). Several short fault segments that have been inferred to have ruptured in 1889 are too short on their own to account for the estimated magnitude. In this paper we perform detailed surveying and trenching of the ~30 km long Saty fault, one of the previously inferred sources, and find that it was formed in a single earthquake within the last 700 years, involving surface slip of up to 10 m. The scarp‐forming event, likely to be the 1889 earthquake, was the only surface‐rupturing event for at least 5000 years and potentially for much longer. From satellite imagery we extend the mapped length of fresh scarps within the 1889 epicentral zone to a total of ~175 km, which we also suggest as candidate ruptures from the 1889 earthquake. The 175 km of rupture involves conjugate oblique left‐lateral and right‐lateral slip on three separate faults, with step overs of several kilometers between them. All three faults were essentially invisible in the Holocene geomorphology prior to the last slip. The recurrence interval between large earthquakes on any of these faults, and presumably on other faults of the Tien Shan, may be longer than the timescale over which the landscape is reset, providing a challenge for delineating sources of future hazard.

Features related to market; namely product characteristics, purchase channel, price and promotion were reported.
Acoustic Aging of Asphalt Pavements: A Californian /Danish Comparison

The level of noise generated by tire/pavement interaction of a pavement section changes over time. While the general consensus is that the noise level tends to increase as the pavement ages, more scientific investigation is necessary to better understand the process of acoustic aging of pavements. For more than a decade, independent studies by Caltrans and the Danish Road Institute (DRI-DK) have included monitoring of tire/pavement noise levels on selected pavements. Using data sets collected as part of those studies, a comprehensive analysis was conducted in this study to characterize the acoustic aging properties of different types of asphalt pavements. Pavement types considered in the analysis include dense-graded asphalt concrete (DGAC), open-graded asphalt concrete (OGAC), thin open-graded asphalt layer, and porous asphalt concrete (PAC). This report presents the results of the data analysis in terms of the relative changes of tire/pavement noise over time for the respective pavements. It also describes the development of an acoustic aging model for asphalt pavements. The model predicts the increase in noise level as a function of pavement age, traffic volume, and pavement type, primarily for highways with speeds over 50 mph. Further study is recommended to improve the prediction model and to integrate the noise model in a Pavement Management System.

Quadrirational Yang-Baxter maps and the Ẽ 8 Painlevé lattice

We establish that the quadrirational Yang-Baxter maps, considered on their symmetry-complete lattice, give an un-normalized form of the Painlevé systems associated with Ẽ8 symmetry. This is a unified representation bringing KdV-type and Painlevé-type systems together outside of the usual paradigm of reductions. Our approach exploits the geometric characterisation of the Painlevé equations and the formulation of both kinds of systems in terms of birational groups.
Longitudinal psychosocial functioning following mastectomywith or without breast reconstruction

Each year in the United Kingdom 48000 women receive a diagnosis of breast cancer (Jemal et at 2014). Most women opt to either have a mastectomy with or without reconstruction (Mortenson et al 2004). The aim of this thesis was to assess the longitudinal psychosocial functioning following mastectomy with or without breast reconstruction. The study highlighted that women who undergo immediate breast reconstruction suffer psychologically and physically more than women who have no reconstruction.
The Microfoundations of Organizational Social Networks

This paper focuses on an emergent debate about the microfoundations of organizational social networks. We consider three theoretical positions: an individual agency perspective suggesting that people, through their individual characteristics and cognitions, shape networks; a network patterning perspective suggesting that networks, through their structural configuration, form people; and a coevolution perspective suggesting that people, in their idiosyncrasies, and networks, in their differentiated structures, coevolve. We conclude that individual attitudes, behaviors, and outcomes cannot be fully understood without considering the structuring of organizational contexts in which people are embedded, and that social network structuring and change in organizations cannot be fully understood without considering the psychology of purposive individuals. To guide future research, we identify key questions from each of the three theoretical perspectives and, particularly, encourage more research on how individual actions and network structure coevolve in a dynamic process of reciprocal influence.
Constrained Average Cost Markov Control Processes in Borel Spaces

This paper considers constrained Markov control processes in Borel spaces, with unbounded costs. The criterion to be minimized is a long-run expected average cost, and the constraints can be imposed on similar average costs, or on average rewards, or discounted costs or rewards. We give conditions under which the constrained problem (CP) is solvable and equivalent to an equality constrained (EC) linear program. Furthermore, we show that there is no duality gap between EC and the dual program EC* and that in fact the strong duality condition holds. Finally, we introduce an explicit procedure to solve CP in some cases which is illustrated with a detailed example.
The Failure of Uncovered Interest Parity: Is it Near-rationality in the Foreign Exchange Market?

A risk-averse US investor adjusts the shares of a portfolio of short-term nominal domestic and foreign assets to maximize expected utility. The optimal strategy is to respond immediately to all new information which arrives weekly. We calculate the expected utility foregone when the investor abandons the optimal strategy and instead optimizes less frequently. We also consider the cases where the investor ignores the covariance between returns sourced in different countries, and where the investor makes unsystematic mistakes when forming expectations of exchange rate changes. We demonstrate that the expected utility cost of sub-optimal behaviour is generally very small. Thus, for example, if investors adjust portfolio shares every three months, they incur an average expected utility loss equivalent to about 0.16% p.a. It is therefore plausible that slight opportunity costs of frequent optimization may outweigh the benefits. This result may help explain the failure of uncovered interest parity.
Estimating the Physical State of a Laboratory Slow Slipping Fault from Seismic Signals

Over the last two decades, strain and GPS measurements have shown that slow slip on earthquake faults is a widespread phenomenon. Slow slip is also inferred from correlated small amplitude seismic signals known as nonvolcanic tremor and low frequency earthquakes (LFEs). Slow slip has been reproduced in laboratory and simulation studies, however the fundamental physics of these phenomena and their relationship to dynamic earthquake rupture remains poorly understood. Here we show that, in a laboratory setting, continuous seismic waves are imprinted with fundamental signatures of the fault's physical state. Using machine learning on continuous seismic waves, we can infer several bulk characteristics of the fault (friction, shear displacement, gouge thickness), at any time during the slow slip cycle. This analysis also allows us to infer many properties of the future behavior of the fault, including the time remaining before the next slow slip event. Our work suggests that by applying machine learning approaches to continuous seismic data, new insight into the physics of slow slip could be obtained in Earth.
a : Individual Characteristics Model : Peer Rejection Deviant Friends Adolescent Rule Breaking c : Sequential Processes Model : b : Additive Model : d : Parallel Processes Model :

Childhood aggression–disruptiveness (AD), chronic peer rejection, and deviant friendships were examined as predictors of early-adolescent rule-breaking behaviors. Using a sample of 383 children (193 girls and 190 boys) who were followed from ages 6 to 14, peer rejection trajectories were identified and incorporated into a series of alternative models to assess how chronic peer rejection and deviant friendships mediate the association between stable childhood AD and early-adolescent rule breaking. There were multiple mediated pathways to rule breaking that included both behavioral and relational risk factors, and findings were consistent for boys and girls. Results have implications for better understanding the influence of multiple social processes in the continuity of antisocial behaviors from middle childhood to early adolescence.
Optimization of the Deposition Parameters of HVOF FeMnCrSi+Ni+B Thermally Sprayed Coatings

HVOF thermal spray process produces coatings with low porosity and low oxide content, as well as high substrate adhesion. Small variations on the parameters of the HVOF process can generate coatings with different characteristics and properties, which also is chemical composition depended of the alloy. FeMnCrSi alloy is a cavitation resistant class of material with a great potential for HVOF deposition use. The main goal of this article is to study the influence of some HVOF parameters deposition, as standoff distance, powder feed rate and carrier gas pressure on three different alloys. FeMnCrSi experimental alloys with some variations in nickel and boron content were studied. Taguchi experimental design with L9 orthogonal array was used in this work. Porosity, oxide content, tensile adhesion strength and microhardness of the coatings were evaluated. The results indicated that all factors have significant influence on these properties. Chemical composition of the alloys was the most important factor, followed by the carrier gas pressure, standoff distance and powder feed rate. The addition of Ni, produces coatings with lower levels of oxide content and porosity. An experiment with improved parameters was conducted, and a great improvement on the coating properties was observed.
MULTISYMPLECTIC VARIATIONAL INTEGRATORS FOR NONSMOOTH LAGRANGIAN CONTINUUM MECHANICS

This paper develops the theory of multisymplectic variational integrators for nonsmooth continuum mechanics with constraints. Typical problems are the impact of an elastic body on a rigid plate or the collision of two elastic bodies. The integrators are obtained by combining, at the continuous and discrete levels, the variational multisymplectic formulation of nonsmooth continuum mechanics with the generalized Lagrange multiplier approach for optimization problems with nonsmooth constraints. These integrators verify a spacetime multisymplectic formula that generalizes the symplectic property of time integrators. In addition, they preserve the energy during the impact. In the presence of symmetry, a discrete version of the Noether theorem is verified. All these properties are inherited from the variational character of the integrator. Numerical illustrations are presented.
