Inducing strong convergence of trajectories in dynamical systems associated to monotone inclusions with composite structure
Authors: Boţ Radu Ioan , Grad Sorin-Mihai , Meier Dennis , Staudigl Mathias 
Published: September 2020

Abstract
In this work we investigate dynamical systems designed to approach the solution sets of inclusion problems involving the sum of two maximally monotone operators. Our aim is to design methods which guarantee strong convergence of trajectories towards the minimum norm solution of the underlying monotone inclusion problem. To that end, we investigate in detail the asymptotic behavior of dynamical systems perturbed by a Tikhonov regularization where either the maximally monotone operators themselves, or the vector field of the dynamical system is regularized. In both cases we prove strong convergence of the trajectories towards minimum norm solutions to an underlying monotone inclusion problem, and we illustrate numerically qualitative differences between these two complementary regularization strategies. The so-constructed dynamical systems are either of Krasnoselskiĭ-Mann, of forward-backward type or of forward-backward-forward type, and with the help of injected regularization we demonstrate seminal results on the strong convergence of Hilbert space valued evolutions designed to solve monotone inclusion and equilibrium problems.
Large data existence theory for three-dimensional unsteady flows of rate-type viscoelastic fluids with stress diffusion
Authors: Bathory Michal , Bulíček Miroslav , Málek Josef 
Published: September 2020

Abstract
We prove that there exists a weak solution to a system governing an unsteady flow of a viscoelastic fluid in three dimensions, for arbitrarily large time interval and data. The fluid is described by the incompressible Navier-Stokes equations for the velocity
v
, coupled with a diffusive variant of a combination of the Oldroyd-B and the Giesekus models for a tensor 𝔹. By a proper choice of the constitutive relations for the Helmholtz free energy (which, however, is non-standard in the current literature, despite the fact that this choice is well motivated from the point of view of physics) and for the energy dissipation, we are able to prove that 𝔹 enjoys the same regularity as
v
in the classical three-dimensional Navier-Stokes equations. This enables us to handle any kind of objective derivative of 𝔹, thus obtaining existence results for the class of diffusive Johnson-Segalman models as well. Moreover, using a suitable approximation scheme, we are able to show that 𝔹 remains positive definite if the initial datum was a positive definite matrix (in a pointwise sense). We also show how the model we are considering can be derived from basic balance equations and thermodynamical principles in a natural way.

Scour Mitigation and Erodibility Improvement Using Microbially Induced Carbonate Precipitation
Authors: Do Jinung , Montoya Brina M. , Gabr Mohammed A. 
Published: September 2020

Abstract
Enhancing the scour resistance of foundation systems supporting superstructures over waterways is required for the sustainable functionality of the structure. In this article, the use of microbially induced carbonate precipitation (MICP) was investigated for the potential of its use in scour mitigation and erodibility improvement of sand. Testing was performed in a 0.91 by 1.22 by 1.22-m model box, and a double wall delivery system was developed and used to target cementation near the surface. A comparative study was performed on the scour behavior of untreated and treated samples using data from a series of flow tests. Impinging jet testing was used to evaluate the erodibility parameters of treated sand. The results from flow testing indicated that untreated and lightly cemented zones showed similar scour depth, whereas indiscernible scour was observed for the heavily cemented zone. The improvement distribution pattern throughout the media showed an ellipsoidal shape with respect to the injection source. The scour behavior and the cementation pattern indicated less cementation was achieved at the zone near the injection source because of high induced seepage velocity. Based on the impinging jet testing results, an empirical erosion model for MICP-treated sand is proposed as a function of the level of cementation.

Published: September 2020

AbstractOligodendrocytes in the central nervous system (CNS) produce myelin sheaths that insulate axons to facilitate efficient electrical conduction. These myelin sheaths contain lamellar microtubules that enable vesicular transport into the inner sheath. Mechanistically, oligodendrocytes rely on Golgi outpost organelles and the associated protein tubulin polymerization promoting protein (TPPP) to nucleate or form new microtubules outside of the cell body. Consequently, elongation of lamellar microtubules is defective inTpppknock-out (KO) mice, which have thinner and shorter myelin sheaths. We now explore the behavioral phenotypes ofTpppKO mice using a number of different assays. In open-field assays,TpppKO mice display similar activity levels and movement patterns as wild-type mice, indicating that they do not display anxiety behavior. However,TpppKO mice lack fear responses by two types of assays, traditional fear-conditioning assays and looming fear assays, which test for innate fear responses. Deficits in fear conditioning, which is a memory-dependent task, as well as in spatial memory tests, support possible short-term memory defects inTpppKO mice. Together, our experiments indicate a connection between CNS myelination and behavioral deficits.
Global longitudinal strain in chronic asymptomatic aortic regurgitation: systematic review
Authors: deCampos Diana , Teixeira Rogério , Saleiro Carolina , Botelho Ana , Gonçalve Lino 
Published: September 2020

Abstract
Chronic aortic regurgitation (AR) patients typically remain asymptomatic for a long time. Left ventricular mechanics, namely global longitudinal strain (GLS), has been associated with outcomes in AR patients. The authors conducted a systematic review to summarize and appraise GLS impact on mortality, the need for aortic valve replacement (AVR) and disease progression in AR patients. A literature search was performed using these key terms ‘aortic regurgitation’ and ‘longitudinal strain’ looking at all randomized and nonrandomized studies conducted on chronic aortic regurgitation. The search yielded six observational studies published from 2011 and 2018 with a total of 1571 patients with moderate to severe chronic AR. Only two studies included all-cause mortality as their endpoint. The other studies looked at the association between GLS with AVR and disease progression. The mean follow-up period was 4.2 years. We noted a great variability of clinical, methodological and/or statistical origin. Thus, meta-analytic portion of our study was limited. Despite a relevant heterogeneity, an impaired GLS was associated with adverse cardiac outcomes. Left ventricular GLS may offer incremental value in risk stratification and decision-making.
De Frankfurt a rio cuarto: cuestiones para el diálogo analógico de la Teoría Crítica y la Filosofía de la Liberación

Published: September 2020

Este artículo tiene dos partes, una plantear el tema de la necesidad del diálogo de la Teoría Crítica con la Filosofía de la Liberación, para aunar esfuerzos en la crítica al capitalismo. La otra, ver algunas relaciones que se dieron en el siglo XX con los pensadores de la Escuela de Frankfurt, que las nuevas generaciones tendrían que retomar. Para que esto sea real y también crítico es necesario que el diálogo sea analógico, que se respeten las diferencias.

Abstract
DNA methylation, a prototypical epigenetic modification implicated in gene silencing, occurs in many eukaryotes and plays a significant role in the etiology of diseases such as cancer. The filamentous fungus Neurospora crassa places DNA methylation at regions of constitutive heterochromatin such as in centromeres and in other A:T-rich regions of the genome, but this modification is dispensable for normal growth and development. This and other features render N. crassa an excellent model to genetically dissect elements of the DNA methylation pathway. We implemented a forward genetic selection on a massive scale, utilizing two engineered antibiotic-resistance genes silenced by DNA methylation, to isolate mutants defective in methylation (dim). Hundreds of potential mutants were characterized, yielding a rich collection of informative alleles of 11 genes important for DNA methylation, most of which were already reported. In parallel, we characterized the pairwise interactions in nuclei of the DCDC, the only histone H3 lysine 9 methyltransferase complex in Neurospora, including those between the DIM-5 catalytic subunit and other complex members. We also dissected the N- and C-termini of the key protein DIM-7, required for DIM-5 histone methyltransferase localization and activation. Lastly, we identified two alleles of a novel gene, dim-10 – a homolog of Clr5 in Schizosaccharomyces pombe – that is not essential for DNA methylation, but is necessary for repression of the antibiotic-resistance genes used in the selection, which suggests that both DIM-10 and DNA methylation promote silencing of constitutive heterochromatin.
Correlation of serum fluorescence of advanced glycation end products with diabetes duration and glycemic control in type 2 diabetic patients
Authors: Ali Sadaf , Rao Nivedita L. 
Published: September 2020

Introduction: Advanced glycation end products (AGEs) and diabetes duration have roles in the development of the vascular complications associated with morbidity and mortality in diabetic patients. The present study was conducted to estimate and find the association between serum fluorescence levels of advanced glycation products with diabetes duration and glycemic control in type 2 diabetic patients.
Methods: 46 patients who had diabetic duration of less than ten years and 49 patients with duration more than ten years were included in the study. Serum fluorescence of AGEs was measured using a simple spectrofluorometric method. Correlations of AGEs with diabetes duration, fasting glucose, and glycated hemoglobin levels were analyzed. The incidence of microvascular complications in patients of both groups was examined.
Results: Significantly higher serum fluorescent AGE levels (p < 0.001) and higher incidence of microvascular complications (p = 0.000) were found in diabetic patients who had diabetes duration of more than ten years, poorer glycemic control and higher age. Serum levels of fluorescent AGEs showed significant positive correlations with duration of diabetes mellitus, glycated haemoglobin and fasting glucose levels.
Conclusion: Screening patients for AGEs, intensive glycemic control, and therapeutic strategies that target molecular mechanisms involving advanced glycation end products are warranted in older patients with longer diabetes duration to minimize their risk of developing complications.
Prevalence and in vitro antibiotic susceptibility pattern of bacterial strains isolated from tribal women suffering from urinary tract infections in District Anuppur, Madhya Pradesh, India
Authors: Sharma Poonam , Netam Aashish Kumar , Singh Rambir 
Published: September 2020

Introduction: Urinary tract infections (UTIs) are an increasing public health problem caused by a range of uropathogens. UTI is a major health concern among tribal women due to lack of adequate health facilities at regional public health centers and district hospitals. The objective of the study was to investigate the prevalence and antibiotic susceptibility of bacteria isolated from urine samples of tribal women suffering from UTI. Urine samples were collected from 550 tribal women who visited the Outpatient Department (OPD) of the District Hospital of Anuppur, Madhya Pradesh, India.
Methods: The samples were cultured on different selective and differential media and identified by colony morphology, Gram staining and biochemical tests.
Results: Out of 550 urine samples, 360 (65.45%) were culture-positive and 190 (34.55%) were culture-negative. Klebsiella pneumoniae, Proteus mirabilis, Escherichia coli & Pseudomonas aeruginosa have been identified as major uropathogens. K. pneumoniae is the most prevalent bacteria followed by P. mirabilis, E. coli and P. aeruginosa. The drug sensitivity analysis of bacterial uropathogens was performed against different antibiotics. The antibiotic susceptibility profiling showed that most of the isolates of K. pneumoniae, P. mirabilis and E. coli were resistant against penicillin (86.67-100%) and rifampicin (72.73-97.67%).
Conclusions: Gentamycin, kanamycin and streptomycin were the most active antibiotics against the isolates of P. aeruginosa (76, 80 and 76%), P. mirabilis (76.62, 66.23 and 75.32%), K. pneumoniae (55.81, 20.93 and 44.19%) and E. coli (50.48, 37.14 and 62.86%), respectively, and may be the drug of choice for treatment of UTI in this region at present.

Lifetime Experiences Scale (LIFES): Development and validation in community samples
Authors: Azevedo Vanessa , Martins Carla , Maia Ângela 
Published: September 2020

This paper describes the development, validation, and reliability of a new measure to assess life experiences reported by adults, the Lifetime Experiences Scale (LIFES). This scale is important because no available measure focuses on both positive and negative life experiences and covers childhood, adolescence, and adulthood. LIFES is a self-report measure consisting of two sections: 75 items (organized into eight domains: school, work, health, leisure, life conditions, adverse experiences, achievements, and people and relationships) regarding lived experiences and blank spaces for non-lived (but desired) experiences. The procedures involved in the development of LIFES are described in detail (e.g., construct, generation of items and questions). Moreover, evidence based on test content, response processes, relations to other variables, and different classes of reliability for community samples are presented. Overall, the results suggest that LIFES presented good evidence of validity and reliability and can be a valuable tool for research and clinical purposes.

Abstract
Operational earthquake forecasts (OEFs) are represented as time-dependent probabilities of future earthquake hazard and risk. These probabilities can be presented in a variety of formats, including tables, maps, and text-based scenarios. In countries such as Aotearoa New Zealand, the U.S., and Japan, OEFs have been released by scientific organizations to agencies and the public, with the intent of providing information about future earthquake hazard and risk, so that people can use this information to inform their decisions and activities. Despite questions being raised about the utility of OEF for decision-making, past earthquake events have shown that agencies and the public have indeed made use of such forecasts. Responses have included making decisions about safe access into buildings, cordoning, demolition safety, timing of infrastructure repair and rebuild, insurance, postearthquake building standards, postevent land-use planning, and public communication about aftershocks. To add to this body of knowledge, we undertook a survey to investigate how agencies and GNS Science staff used OEFs that were communicated following the Mw 7.8 2016 Kaikōura earthquake in Aotearoa New Zealand. We found that agencies utilized OEFs in many of the ways listed previously, and we document individual employee’s actions taken in their home-life context. Challenges remain, however, regarding the interpretation of probabilistic information and applying this to practical decision-making. We suggest that science agencies cannot expect nontechnical users to understand and utilize forecasts without additional support. This might include developing a diversity of audience-relevant OEF information for communication purposes, alongside advice on how such information could be utilized.
The Western Limit of Iapetan Rifting in the Eastern United States: A New Assessment
Authors: Powell Christine A. , Thomas William A. , Hatcher Robert D. 
Published: September 2020

AbstractSpecifying the extent and location of rifted, crystalline Precambrian crust in the eastern United States is important for seismic hazard evaluation and for models that relate upper-mantle structure to ancient tectonic features and ongoing tectonism. As currently depicted in the National Seismic Hazard Maps (NSHM), the western limit of Iapetan rifted crust is beneath the Appalachian plateau physiographic province, west of the Valley and Ridge province. New estimates of crustal thickness using EarthScope Transportable Array and other data do not support the presence of rifted crust beneath the Blue Ridge, Valley and Ridge, and Appalachian plateau physiographic provinces. Crustal thicknesses exceed 45 km throughout most of this region. The crust thins to the southeast beneath the southeastern part of the Piedmont physiographic province and is only 36 km thick near the edge of the Atlantic coastal plain. We suggest that the western limit of Iapetan rift-extended crust is east of the Blue Ridge province and is associated with the prominent Appalachian gravity gradient. This location coincides with palinspastic reconstructions based on geologic data for the Iapetan rifted margin. Recognition of thick crust beneath the Blue Ridge and Valley and Ridge provinces, unextended by Iapetan rifting, will support more robust modeling of the effects of mantle structure (such as delamination and abrupt changes in lithospheric thickness) on ongoing tectonism and earthquake activity in the eastern United States and will provide more accurate seismotectonic zonation in the NSHM.

Published: September 2020

AbstractMoho morphology in orogens provides important constraints on the rheology and density structure of the crust and underlying mantle. Previous studies of Moho geometry in the northern Canadian Cordillera (NCC) using very sparse seismic data have indicated a flat and shallow (∼30–35  km) Moho, despite an average elevation of &gt;1000  m above sea level attributable to increased thermal buoyancy and lower crustal flow due to elevated temperatures. We estimate Moho depth using receiver functions from an expanded dataset incorporating 173 past and recently deployed broadband seismic stations, including the EarthScope Transportable Array, Mackenzie Mountains transect, and other recent deployments. We determine Moho depths in the range 27–43 km, with mean and standard deviations of 33.0 and 3.0 km, respectively, and note thickened crust beneath high-elevation seismogenic regions. In the Mackenzie Mountains, thicker crust is interpreted as due to crustal stacking from thrust sheet emplacement. The edge of this region of thickened crust is interpreted to delineate the extent of the former Laurentian margin beneath the NCC and is associated with a transition from thrust to strike-slip faulting observed in regional seismicity. More geographically extensive seismograph deployments at EarthScope Transportable Array density and scale will be required to further extend crustal-scale and lithosphere-scale imaging in western Canada.
