Structural Controls on Stress and Microseismic Response - A Horn River Basin Case Study
Authors: Snelling Paige , de Groot Michael , Craig Cecilia , Hwang KyuBum 
Published: November 2013

Abstract
This study demonstrates that geologic structure can significantly alter stresses within the completion zone and change the characteristics of microseismicity. Completions and microseismic data are used to examine the effects of geologic structure on an executed completions program. The microseismic was recorded on a 98-station near-surface array for approximately 200 stages on 7 wells. Two prominent faults are identified using microseismic data. The differences between microseismic event populations from hydraulic fracture stimulation and fault reactivation are assessed in terms of event source mechanisms and event parameters.
We examine changes in calculated bottomhole instantaneous shut-in pressure (ISIP) gradient near faults and the associated change in microseismic behavior. Stress regime, maximum horizontal stress (SHmax) directions and stress magnitudes along faults are examined with a stress inversion approach using source mechanism information.
Results show that hydraulic fractures, particularly in the Muskwa shales, have high b-values and tend to be characterized by dip-slip failures. Events relating to fault reactivation are characterized by strike-slip events and have low b-values. The orientations of SHmax derived from stress inversion for fault populations align with regional SHmax estimates from regional borehole breakout measurements. Stages intersected by prominent faults show significant increases in measured ISIP, which are more pronounced in the Evie completion zone.

Published: November 2013

SUMMARY

Objectives
This study aimed to assess the retention of metal copings luted to uremic teeth with five different luting agents.

Methods
A total of 35 sound natural molars was collected from uremic patients and randomly assigned into five groups (n=7). The teeth were prepared for metal copings using diamond tips and water coolant. Metal copings with a loop on the occlusal surface were fabricated using base metal alloy (Rexillium III). The copings were luted using Fuji I, glass ionomer (GI); Fuji Plus, resin-modified glass ionomer (RMGI); Panavia F 2.0, resin cement; Rely X Unicem, self-adhesive cement (SA); and Adhesor, zinc phosphate cement (ZPh). All specimens were incubated at 37°C for 24 hours, conditioned in artificial saliva for 7 days, and then thermocycled for 5000 cycles (5°C-55°C). The dislodging force was measured using a universal testing machine at a crosshead speed of 2 mm/min. The mode of failure of the loaded adhesive copings was evaluated. Statistical analyses were performed using one-way analysis of variance and Tukey post hoc test.

Results
GI and SA cements had the highest and the lowest mean retentive strength, respectively (580.90±17.3, 406.6±12.7). There was no significant difference between ZPh, SA, and resin cements. These cements were inferior to GI and RMGI cements (p&lt;0.05), which showed statistically similar retentive strengths.

Conclusions
The results of this study support the use of glass ionomer and resin-modified glass ionomer cements for luting of metal copings to uremic teeth with retentive preparations.
Existence and uniqueness of solutions to weakly singular integral-algebraic and integro-differential equations

Published: November 2013

Abstract
We consider systems of integral-algebraic and integro-differential equations with weakly singular kernels. Although these problem classes are not in the focus of the main stream literature, they are interesting, not only in their own right, but also because they may arise from the analysis of certain classes of differential-algebraic systems of partial differential equations. In the first part of the paper, we deal with two-dimensional integral-algebraic equations. Next, we analyze Volterra integral equations of the first kind in which the determinant of the kernel matrix k(t, x) vanishes when t = x. Finally, the third part of the work is devoted to the analysis of degenerate integro-differential systems. The aim of the paper is to specify conditions which are sufficient for the existence of a unique continuous solution to the above problems. Theoretical findings are illustrated by a number of examples.
L’impact de l’unification des aides au logement sur le profil de consommation des bénéficiaires
Authors: Mahieu Ronan 
Published: November 2013

The impact of unifying housing benefits on beneficiaries’ consumer profiles.
Individual housing benefits in the rental sector can serve a two-fold objective : increase expenditure for other consumption items (or savings) by increasing the disposable income after factoring housing expenditure but also, of course, increasing housing consumption by facilitating access to larger or more comfortable (and thus more expensive) housing, which assumes that the beneficiary moves. Here the unification occurring between 2000 and 2002 in the scale applied by two types of current aid, housing benefits [ allocation logement] and individual housing aid [ aide personnalisée au logement] is used as the natural experiment to highlight the impact of benefits on the decision to move. The data used are those from the Caisses d’Allocations familiales, which pay out housing benefits. Although it is difficult to quantify the effect of subsidies with precision given the inability to identify changes of address in the sources used, the study does reveal a significant positive effect, albeit of minor extent, from benefits for recipients’ residential mobility. Furthermore, the effect of benefits differs highly from one region to the next, possible as a result of local housing market specifics.

Published: November 2013

SummaryBackground: Similarity measures in medical images do not uniquely determine the correspondence between two voxels in deformable image registration. Uncertainties in the final computed deformation exist, questioning the actual physiological consistency of the deformation between the two images.Objectives: We developed a deformable image registration method that regularizes the deformation field in order to model a deformation with physiological properties, relying on vector calculus based operators as a regularization function.Method: We implemented a 3D multi-resolution parametric deformable image registration, containing divergence and curl of the deformation field as regularization terms. Exploiting a BSpline model, we fit the transformation to optimize histogram-based mutual information similarity measure. In order to account for compression/expansion, we extract sink/source/circulation components as irregularities in the warped image and compensate them. The registration performance was evaluated using Jacobian determinant of the deformation field, inverse-consistency, landmark errors and residual image difference along with displacement field errors. Finally, we compare our results to a robust combination of second derivative regularization, as well as to non-regularized methods.Results: The implementation was tested on synthetic phantoms and clinical data, leading to increased image similarity and reduced inverse-consistency errors. The statistical analysis on clinical cases showed that regularized methods are able to achieve better image similarity than non regularized methods. Also, divergence/curl regularization improves anatomical landmark errors compared to second derivative regularization.Conclusion: The implemented divergence/ curl regularization was successfully tested, leading to promising results in comparison with competitive regularization methods. Future work is required to establish parameter tuning and reduce the computational cost.

Published: November 2013

ABSTRACTA commitment to receive input from stakeholders is often obligatory in the crafting of environmental policies. This requirement is presumed to satisfy certain conditions of democracy. In this article, by drawing from pragmatism, we examine the logic of participation and prerequisites of the meaningful game of asking for and giving reasons. We elaborate the nature and significance of three components—the game, the pleadings, and the reasons. We conclude by offering the conditions under which the stakeholder game might be considered legitimate.

La Importancia de los Determinantes Colectivos del Desempeño en la Evaluación de Competencias
Authors: Andrés Pucheu Juan 
Published: November 2013

Hoy en día es posible observar el uso de múltiples modelos de competencias, lamayoría de los cuales asume que la capacidad o competencia es una propiedad delindividuo y que este la puede ejercer con independencia de factores colectivos uorganizacionales. Esta falta de consideración por los determinantes colectivos oambientales del desempeño es una debilidad que no sólo no corresponde al estado actual de las teorías científicas sobre personalidad, si no que además puede originar aplicaciones infructuosas e incluso la asignación inadecuada de responsabilidades ante deficiencias en el desempeño. Este artículo presenta una modelo de análisis que remedia estas carencias y señala dos ejemplos de aplicación obtenidos en estudios de consultoría e investigación académica.
Safety of Human Neural Stem Cell Transplantation in Chronic Spinal Cord Injury

Published: November 2013

Abstract
The spinal cord injury (SCI) microenvironment undergoes dynamic changes over time, which could potentially affect survival or differentiation of cells in early versus delayed transplantation study designs. Accordingly, assessment of safety parameters, including cell survival, migration, fate, sensory fiber sprouting, and behavioral measures of pain sensitivity in animals receiving transplants during the chronic postinjury period is required for establishing a potential therapeutic window. The goal of the study was assessment of safety parameters for delayed transplantation of human central nervous system-derived neural stem cells (hCNS-SCns) by comparing hCNS-SCns transplantation in the subacute period, 9 days postinjury (DPI), versus the chronic period, 60 DPI, in contusion-injured athymic nude rats. Although the number of surviving human cells after chronic transplantation was lower, no changes in cell migration were detected between the 9 and 60 DPI cohorts; however, the data suggest chronic transplantation may have enhanced the generation of mature oligodendrocytes. The timing of transplantation did not induce changes in allodynia or hyperalgesia measures. Together, these data support the safety of hCNS-SCns transplantation in the chronic period post-SCI.

AbstractWe previously demonstrated that the intravenous delivery of multipotent adult progenitor cells (MAPCs) after traumatic brain injury (TBI) in rodents provides neuroprotection by preserving the blood-brain barrier and systemically attenuating inflammation in the acute time frame following cell treatment; however, the long-term behavioral and anti-inflammatory effects of MAPC administration after TBI have yet to be explored. We hypothesized that the intravenous injection of MAPCs after TBI attenuates the inflammatory response (as measured by microglial morphology) and improves performance at motor tasks and spatial learning (Morris water maze [MWM]). MAPCs were administered intravenously 2 and 24 hours after a cortical contusion injury (CCI). We tested four groups at 120 days after TBI: sham (uninjured), injured but not treated (CCI), and injured and treated with one of two concentrations of MAPCs, either 2 million cells per kilogram (CCI-2) or 10 million cells per kilogram (CCI-10). CCI-10 rats showed significant improvement in left hind limb deficit on the balance beam. On the fifth day of MWM trials, CCI-10 animals showed a significant decrease in both latency to platform and distance traveled compared with CCI. Probe trials revealed a significant decrease in proximity measure in CCI-10 compared with CCI, suggesting improved memory retrieval. Neuroinflammation was quantified by enumerating activated microglia in the ipsilateral hippocampus. We observed a significant decrease in the number of activated microglia in the dentate gyrus in CCI-10 compared with CCI. Our results demonstrate that intravenous MAPC treatment after TBI in a rodent model offers long-term improvements in spatial learning as well as attenuation of neuroinflammation.

AbstractCerebrofaciothoracic dysplasia (CFT) (OMIM #213980) is a multiple congenital anomaly and intellectual disability syndrome involving the cranium, face, and thorax. The characteristic features are cranial involvement with macrocrania at birth, brachycephaly, various CT/MRI findings including hypoplasia of corpus callosum, enlargement of septum pellicidum, and diffuse hypodensity of the grey matter, flat face, hypertelorism, cleft lip and cleft palate, low‐set, posteriorly rotated ears, short neck, and multiple costal and vertebral anomalies. The underlying genetic defect remains unknown. Using combination of homozygosity mapping and whole‐exome sequencing, we identified a homozygous nonsense founder mutation, p.Arg87Ter (c.259 C>T), in the human transmembrane and coiled‐coil domains protein 1 (TMCO1) in four out of five families of Turkish origin. The entire critical region on chromosome 1q24 containing TMCO1 was excluded in the fifth family with characteristic findings of CFT providing evidence for genetic heterogeneity of CFT spectrum. Another founder TMCO1 mutation has recently been reported to cause a unique genetic condition, TMCO1‐defect syndrome (OMIM #614132). TMCO1‐defect syndrome shares many features with CFT. This study supports the fact that “TMCO1‐defect syndrome,” initially thought to represent a distinct disorder, indeed belongs to the genetically heterogeneous CFT dysplasia spectrum. © 2013 Wiley Periodicals, Inc.

ABSTRACTRoot cortex of Paeonia suffruticosa Andrews (Paeoniaceae), known as Moutan Cortex (MC), is known to have anti‐allergic and anti‐inflammatory properties. However, the constituents absorbed into blood after oral administration of MC remain unknown. A sensitive and rapid method by ultra‐high‐pressure liquid chromatography–electrospray ionization–quadrupole‐time‐of‐flight mass spectrometry (UPLC‐ESI‐Q‐TOF‐MS) technology and the MetaboLynxTM software combined with multiple data processing approach (Mdpa) was established to investigate the absorbed constituents in rats after oral administration of MC, providing unique high‐throughput capabilities for drug metabolism study. A hyphenated electrospray ionization and quadrupole‐time‐of‐flight analyzer was used for the determination of accurate mass of the fragment ion in negative mode, with excellent MS mass accuracy and enhanced data acquisition. This rapid automated analysis method was successfully applied for screening and identification of the constituents absorbed and metabolized studies of MC after oral administration to rats. A total of 46 peaks were obtained from MC, 41 of which were tentatively characterized. In the VIP‐plot of orthogonal partial least‐squares discriminant analysis, 23 interesting ions in serum samples were extracted, and 16 parent components and seven metabolites were detected in vivo. The integrative serum pharmacochemistry technique, UPLC‐ESI‐Q‐TOF‐MS, and Mdpa method were successfully applied for rapid discovery of multiple components from MC.

ABSTRACTBackgroundThere are limited data regarding the impact of atherosclerosis detection by carotid ultrasound (CUS) on physician prevention efforts and risk‐factor management for cardiovascular disease.HypothesisAtherosclerosis detection by CUS in asymptomatic hypertensive patients would lead to physician prevention efforts, including target low‐density lipoprotein cholesterol (LDL‐C) level and prescription. Also, it may improve risk‐factor management.MethodsA total of 347 asymptomatic hypertensive subjects (age 61 ± 8 years, 189 men) were prospectively recruited from 22 hospitals. Prior to CUS, physicians were surveyed regarding target LDL‐C level. After CUS, patients were classified into positive CUS (n = 182) and negative CUS (n = 165) groups based on CUS results. Physicians were resurveyed to assess whether the initial target LDL‐C goals were changed. At 6 months, cardiovascular risk‐factor modification status was reassessed.ResultsThe proportion of lowered target LDL‐C levels was significantly larger in the positive CUS group than in the negative CUS group (52% vs 23%, P < 0.001). These results were observed even in subjects who had low and moderate risk according to National Cholesterol Education Program–Adult Treatment Panel III guidelines. Lipid‐lowering agents were similarly added or switched to another class in both groups (7% in the positive CUS group vs 11% in the negative CUS group, P = 0.153). LDL‐C was significantly decreased in the positive CUS group (Δ = −24 ± 38 mg/dL, P < 0.001), whereas it was not significantly decreased in the negative CUS group (Δ = −6 ± 31 mg/dL, P = 0.105).ConclusionsAtherosclerosis detection by CUS lowered physicians' target LDL‐C level and improved cardiovascular risk management in terms of LDL‐C reduction.
