AbstractAim: Insecure attachment may influence vulnerability to and outcome of psychotic symptomatology. The present study examined whether attachment style predicted symptoms and functioning of at‐risk mental state (ARMS) patients after 6 months of psychosocial intervention, over and above the effects of initial clinical severity and premorbid social adjustment (PSA).Methods: Symptoms and functioning were assessed at baseline and 6 months later in 31 ARMS patients (mean age = 15.7). No patient received antipsychotic medication, but all engaged in intense psychosocial needs‐adapted treatment. Clinicians (unaware of the aims of the study) rated attachment, PSA, symptoms, and functioning.Results: Attachment was not related to baseline clinical severity. However, improvement in psychoticism was predicted by attachment (in particular by secure, preoccupied and dismissing) beyond the effects of baseline clinical severity and PSA. Secure attachment also predicted improvements in disorganization and functioning. Poor PSA predicted less improvement in disorganization and negative symptoms but did not impact psychoticism.Conclusions: The three attachment prototypes that predicted improvement in psychoticism (secure, preoccupied and dismissing) share the existence of at least one positive psychological model (either about self or about others). It may be that the psychosocial intervention helped ARMS patients to disconfirm negative models and/or reinforce positive ones. Patients' attachment styles were not related to baseline clinical severity but impacted improvement of positive symptoms. These findings appear consistent with evidence that impaired self‐esteem and dysfunctional self and others schemas constitute risk factors for reality distortion.

Journal of the American Water Resources Association (JAWRA) 48(3): 603‐615. DOI: 10.1111/j.1752‐1688.2011.00635.xAbstract:  Public investment in urban stream restoration is growing, yet little has been done to quantify whether its benefits outweigh its cost. The most common drivers of urban stream projects are water quality improvement and infrastructure protection, although recreational and aesthetic benefits are often important community goals. We use standard economic methods to show that these contributions of restoration can be quantified and compared to costs. The approach is demonstrated with a case study in Baltimore, Maryland, a city with a legal mandate to reduce its pollutant load. Typical urban stream restoration costs of US$500‐1,200 per foot are larger than the cost of the least expensive alternatives for management of nitrogen loads from stormwater (here, detention ponds, equivalent to $30‐120 per foot of restored stream) and for protecting infrastructure (rip‐rap armoring of streambanks, at $0‐120 per foot). However, the higher costs of stream restoration can in some cases be justified by its aesthetic and recreational benefits, valued using a contingent valuation survey at $560‐1,100 per foot. We do not intend to provide a definitive answer regarding the worth of stream restoration, but demonstrate that questions of worth can be asked and answered. Broader application of economic analysis would provide a defensible basis for understanding restoration benefits and for making restoration decisions.

Whittemore, Donald O., 2012. Potential Impacts of Stormwater Runoff on Water Quality in Urban Sand Pits and Adjacent Groundwater. Journal of the American Water Resources Association (JAWRA) 48(3): 584‐602. DOI: 10.1111/j.1752‐1688.2011.00637.xAbstract:  Entrance of stormwater runoff into water‐filled pits and adjacent aquifers is a contamination concern. The water and sediment quality in several sand pits and surrounding groundwater in Wichita, Kansas, were studied to comprehensively address stormwater runoff impact. The pits are used for residential development after sand and gravel mining. Water samples were analyzed for inorganic constituents, bacteria, and 252 organic compounds, and pit sediments for inorganic components and 32 organic chemicals. Although many pesticide and degradate compounds were found in the pit and well waters, none of these chemicals exceeded existing health levels. Other organic contaminants were detected in the waters, with those exceeding health levels at one site attributed to an undiscovered groundwater contamination plume and not to stormwater runoff. Persistent insecticides and polychlorinated biphenyls detected in sediment of two pits are related to the age of residential development. The concentration distributions of pesticides and other organics at most of the sites, as well as iron, manganese, and ammonia patterns in downgradient well waters relative to upgradient well and pit waters, indicate that groundwater quality at the sites is affected by contaminants entering the pit surface waters. Thus, although current stormwater runoff does not appear to have contaminated sand‐pit water and adjacent groundwater above health levels, the data show that the potential exists if stormwater became polluted.

AbstractIntroduction:  Physical activity (PA) is important in preventing disease, but endurance elite athletes have increased prevalence of asthma and airway inflammation.Objectives:  We aimed to determine if PA was associated with increased fractional exhaled nitric oxide (FENO) in asthmatic and non‐asthmatic adolescents.Methods:  FENO was recorded (Niox Mino®, Aerocrine AB, Stockholm, Sweden) in 169 adolescents (13–14 years) in a nested case–control analysis from the Environment and Childhood Asthma study, Oslo, 92 adolescents with and 77 without asthma. They underwent clinical examination, lung function measurements and treadmill run measuring peak oxygen uptake, and objectively recorded PA for four consecutive days. PA was classified as moderate, vigorous and very vigorous, and total number of hours of each category was recorded for each subject. Associations between FENO and PA were tested using linear robust multiple regression analyses.Results:  In non‐asthmatic adolescents, FENO was associated with daily hours of vigorous to very vigorous (r = 0.27, P = 0.02) and very vigorous PAs (r = 0.25, P = 0.036) in bivariate analyses. In multivariate analyses, FENO was associated with vigorous to very vigorous PA [regression coefficients (95% confidence interval) 1.9 (0.6, 3.1); P = 0.004] and more strongly with very vigorous PA [3.9 (1.5, 6.4); P = 0.002] in non‐asthmatic but not in asthmatic adolescents. Total daily PA was not associated with FENO in either group. Thus, 1 h of very vigorous PA per day increased FENO by 3.9 ppb.Conclusion:  Vigorous to very vigorous PA, contrasting total daily PA, was significantly associated with increased FENO in non‐asthmatic adolescents, suggesting that intensive PA may induce airway inflammation independent of asthma.Please cite this paper as: Sachs‐Olsen C, Berntsen S, Lødrup Carlsen K, Anderssen SA, Mowinckel P and Carlsen K‐H.

AbstractAimTo elucidate the pathophysiology of rheumatoid arthritis (RA) as well as osteoarthritis (OA), we analyzed protein profiles of bone marrow‐derived adherent cells (BMACs) from patients with these diseases.MethodsProteins, extracted from BMACs from three RA and three OA patients, were comprehensively analyzed by 2‐dimensional differential image gel electrophoresis (2D‐DIGE). Then a part of the detected proteins, differently expressed between the two diseases, were identified by mass spectrometric analysis.Results2D‐DIGE analysis detected more than 1600 protein spots in both RA and OA BMACs. Out of these, expression of 340 spots was significantly altered between the diseases (more than 1.5‐fold: RA > OA, 26 spots; OA > RA, 314 spots; P < 0.05). Eleven protein spots the intensity of which were significantly altered by more than 2.0‐fold were identified, which included vimentin and annexin A5 as increased proteins in RA rather than in OA. As increased proteins in OA compared to RA, alpha chain of collagen VI, a membrane anchor for acetylcholine esterase, heat shock protein 27, caldesmon and cytoskeletal proteins, such as beta actin and alpha tubulin, were identified.ConclusionsWe here report different protein profiles of BMACs between RA and OA for the first time. BMACs possessing differently expressed proteins may be involved in the pathophysiology of the two diseases.

AbstractAimWe aimed to determine the prevalence and characteristics of adverse drug events (ADE) in rheumatoid arthritis (RA) and (osteoarthritis) OA patients.MethodA cross‐sectional study at rheumatology clinics, was performed by random selection of RA and OA out‐patients by a research pharmacist. All suspected ADEs occurring during the last hospital visit and the subjects were identified by retrospective chart review and direct patient interview. ADE characteristics, including causative drug groups, affected organ severity and patient outcomes, were recorded.ResultsOne hundred and forty‐three patients consisting of 129 RA and 14 OA were recruited. The patients’ mean ages were 54.3 ± 14.3 years and 121 (84.6%) patients were female. A total of 68 ADEs were detected in 51 patients. The prevalence and rate of ADE were 35.7% and 47.6 events per 100 patients, respectively. Thirty out of 68 ADEs (44.1%) were preventable. Disease‐modifying anti‐rheumatic drugs and non‐steroidal anti‐inflammatory drugs resulted in ADEs by 41 (59.4%) and 10 (14.5%) events, respectively. Common affected organs were skin, gastrointestinal tract and eyes which accounted for 20 (29.4%), 18 (26.5%) and eight events (11.6%), respectively. Continuation of the suspected drug was noted in 42 ADEs (61.8%), classified as severity level 1 and 2a‐b, and 43 ADEs (63.2%) were completely or partially resolved during the study period.ConclusionADEs are common in RA and OA patients with prevalence of 35.7%. High exposure to potentially harmful drugs might explain the higher rate of ADE in these patients.

AbstractAimTo examine the prevalence of sicca symptoms and secondary Sjögren's syndrome (sSS) in rheumatoid arthritis (RA) patients, and the impact of sSS on disease activity and treatment profile in RA patients.MethodsThree hundred and seven RA patients responding positive to at least one of the questions in a questionnaire about sicca symptoms, were examined by Schirmer I test for tear production, and unstimulated whole saliva collection (USWC). Secondary Sjögren's syndrome was defined by at least one subjective sicca symptom, in addition to a positive Schirmer I test and positive USWC.ResultsAmong the 307 RA patients, 86 (28%) responded positive to at least one question about sicca symptoms, and 11 patients were positive for both Schirmer I and USWC tests, giving a minimum prevalence of sSS at 3.6%. There were no differences in RA patients with and without sSS regarding age, sex, disease duration, disease activity score (DAS‐28) and seropositivity for anti‐cyclic citrullinated protein. RA patients with sSS had a tendency for higher numbers of tender and swollen joints and pain. None of the RA patients treated with tumor necrosis factor (TNF) inhibitors had sSS, compared to 22% of the rest of the RA population studied. The treatment of the RA patients with and without sSS was not different.ConclusionAmong the 307 RA patients, 28% had at least one sicca symptom. The estimated minimum of prevalence of sSS in 307 RA patients was 3.6%. Secondary Sjögren's syndrome was not found in RA patients treated with biologics such as TNF blockers.

AbstractAimThis study was designed to investigate adherence to anti‐osteoporotic regimens in a population following therapeutic guidelines; and to assess whether this experience differs from that in other administrative surveys.MethodsWe reviewed an outpatient database to retrieve information on prescription of anti‐osteoporotic medications at a medical centre in Taiwan from 2001 to 2007. Adherence was determined by compliance and persistence. Compliance was calculated by the medication possession ratio (MPR), and persistence by the time from treatment initiation to discontinuation. All anti‐osteoporotic regimens were considered equivalent in this study.ResultsA total of 3589 patients (3256 women and 333 men), with a mean age of 68.6 years, were included. The median MPR at 1 year and at 2 years were 99.7% (interquartile range [IQR] 26.8–100) and 61.4% (IQR 15.3–100), respectively. Good compliance (MPR ≥ 80%) was 56% at 1 year and 43% at 2 years. Regarding the 30‐day refill gap, mean duration of persistence at 1 year and at 2 years was 243 and 400 days, respectively. About 50.8% of patients continued to receive therapy at 1 year, while 36.1% at 2 years. Our findings are not different from those of other claims‐based studies. The subgroup with MPR ≥ 80% had a higher persistence rate than that with MPR < 80%.ConclusionOverall adherence to anti‐osteoporotic regimens based on guidelines was sub‐optimal in the current study. Our results are in line with previous studies using a claims database. Non‐adherence commonly occurs early after drug initiation, which indicates that efforts should be made to improve adherence as soon as possible.
The power series technique and detection of zero-group velocity Lamb waves in a functionally graded material plate

Published: February 2012

This paper presents a technique for measuring the variation of the material properties along the thickness in a functionally graded material (FGM) plate. To investigate the propagation behavior of Lamb waves in a thermal stress relaxation type FGM plate with material parameters that vary continuously along the thickness, the power series technique, which has been proved to have good convergence and high precision, is employed for theoretical derivations. The method exploits the resonance at the minimum frequency of the S1 - zero group velocity (ZGV) mode. At this minimum frequency (f0), the group velocity vanishes, whereas the phase velocity remains finite. The numerical results also reveal differences between the ZGV frequency in the FGM plate and the corresponding frequency in a homogenous plate. In terms of results, we find that the in-plane and out-plane displacements are different between Al-rich and Si-rich surfaces. The plots of the involved stresses within the plate are added to check the performed calculations. Besides, the study covers the sensitivity of S1-ZGV resonance frequency to the FGM character and any slight variation of the plate thickness. All these results give theoretical guidance not only for experimental measurement of material properties but also for nondestructive evaluation using an ultrasonic wave generation device.
Exact solutions of Wick-type stochastic Korteweg – de Vries equation
Authors: Zhang Sheng 
Published: February 2012

An algorithm is devised for using the compatibility method to find symmetries and similarity reductions of Wick-type stochastic partial differential equations. To illustrate the validity and advantages of the devised algorithm, the Wick-type stochastic Korteweg – de Vries equation is considered. With the aid of Hermite transformation and white noise theory, we obtain a symmetry and corresponding reduction of the Wick-type stochastic Korteweg – de Vries equation. Furthermore, some new similarity solutions are obtained including Jacobi elliptic function solutions, hyperbolic function solutions, and trigonometric function solutions.
CENTROID TRIANGULATIONS FROM k-SETS

Published: February 2012

Given a set V of n points in the plane, no three of them being collinear, a convex inclusion chain of V is an ordering of the points of V such that no point belongs to the convex hull of the points preceding it in the ordering. We call k-set of the convex inclusion chain, every k-set of an initial subsequence of at least k points of the ordering. We show that the number of such k-sets (without multiplicity) is an invariant of V, that is, it does not depend on the choice of the convex inclusion chain. Moreover, this number is equal to the number of regions of the order-k Voronoi diagram of V (when no four points are cocircular). The dual of the order-k Voronoi diagram belongs to the set of so-called centroid triangulations that have been originally introduced to generate bivariate simplex spline spaces. We show that the centroids of the k-sets of a convex inclusion chain are the vertices of such a centroid triangulation. This leads to the currently most efficient algorithm to construct particular centroid triangulations of any given point set; it runs in O(n log n + k(n - k) log k) worst case time.

We consider a geometric optimization problem that arises in sensor network design. Given a polygon P (possibly with holes) with n vertices, a set Y of m points representing sensors, and an integer k, 1 ≤ k ≤ m. The goal is to assign a sensing range, ri, to each of the sensors yi ∈ Y, such that each point p ∈ P is covered by at least k sensors, and the cost, [Formula: see text], of the assignment is minimized, where α is a constant. In this paper, we assume that α = 2, that is, find a set of disks centered at points of Y, such that (i) each point in P is covered by at least k disks, and (ii) the sum of the areas of the disks is minimized. We present, for any constant k ≥ 1, a polynomial-time c1-approximation algorithm for this problem, where c1 = c1(k) is a constant. The discrete version, where one has to cover a given set of n points, X, by disks centered at points of Y, arises as a subproblem. We present a polynomial-time c2-approximation algorithm for this problem, where c2 = c2(k) is a constant.
Mesozoic and Cenozoic evolution of salt structures within the Polish basin: An overview
Authors: Krzywiec Piotr 
Published: February 2012

Abstract
The Permian–Cretaceous Polish Basin belonged to the system of epicontinental depositional basins of Western and central Europe and was filled with several kilometres of siliciclastics, carbonates, and also thick Zechstein (approximately Upper Permian) evaporites. Its axial part (the so-called Mid-Polish Trough) characterized by the thickest Permo-Mesozoic sedimentary cover, developed above the Teisseyre–Tornquist Zone, lithospheric-scale boundary separating the East European Craton and the Palaeozoic Platform. The Polish Basin was inverted in Late Cretaceous–Paleocene times. A synthesis of studies based on seismic reflection data allowed some general rules regarding salt tectonics of the Polish Basin to be formulated. Two general classes of structures genetically related to the presence of the Zechstein evaporites have been described: peripheral structures located within NE and SW flanks of the Polish Basin, outside its axial part and structures located within its axial part. The first class of structures includes grabens bounded by listric faults detached above salt or salt pillows that developed where Zechstein evaporites were of relatively smaller thickness and where sub-Zechstein fault tectonics played a relatively smaller role. The second class of structures includes more mature salt structures such as salt pillows and salt diapirs and is related to the more axial part of the basin, characterized by relatively thicker Zechstein evaporites and by more intense basement tectonics. First salt movements (salt pillowing) took place in the Early Triassic that in certain cases was followed by the Late Triassic salt diapirism and extrusion. In Jurassic–Early Cretaceous times, no significant growth of salt structures took place. Most of the salt diapirs have been finally shaped by the Late Cretaceous inversion tectonics. Some salt diapirs also underwent Cenozoic reactivation, associated with localized Oligocene or Miocene subsidence that in some cases was followed by younger (Pliocene–Quaternary) inversion and uplift.
Regional-scale structural role of Permian salt within the Central European Basin System

Published: February 2012

Abstract
The Central European Basin System (CEBS) includes the former Northern and Southern Permian Basins together with superimposed Meso-Cenozoic sub-basins and contains a thick layer of Upper Permian (Zechstein) salt. This salt was mobilized in response to several post-Permian tectonic events. In order to analyse the regional relationship between the structural pattern of the Meso-Cenozoic sedimentary cover and the distribution of the Upper Permian salt, a 3D structural model of the CEBS has been constructed. In this model, the Permian salt is resolved as an extra layer for the entire basin system. According to the 3D structural model, the salt layer is strongly deformed as a result of halokinetic activity. The thickest salt is localized within salt walls and diapirs, reaching up to 9 km of thickness. A regional structural 3D analysis of the overburden in relation to underlying ductile salt demonstrates that the geometry of the sedimentary cover is strongly complicated by a variety of salt structures. The withdrawal of the Permian salt appears to have played a key role in both deposition and deformation of Meso-Cenozoic deposits in addition to tectonically forced regional subsidence.
