Characterization of AISI 316L Stainless Steel Pattern via DC Plasma Nitriding | Aiming to produce a pattern on the surface of austenitic stainless steel, AISI 316L, cylindrical samples were plasma nitrided with copper grids (the same are used in Transmission Electron Microscopy (TEM)) accommodated on the surface. Samples were positioned at the cathode and process was performed according to following constant parameters: temperature of 400 °C, pressure of 3 Torr and treatment time of 2h. In order to evaluate the difference in the pattern produced, three different gas mixtures were used: poor in nitrogen (5% N2/95% H2), rich in nitrogen (95% N2/5% H2) and a gas mixture with addition of argon (80% N2/10% H2/10% Ar). After nitriding, samples were characterized by optical interferometry (OI), scanning electron microscopy (SEM), optical microscopy (OM), micro hardness test and, X-ray diffraction (XRD). The results showed the presence of a mask (TEM grid) promotes the surface patterning of steel. This patterning is associated with high residual compressive stress induced by the introduction of a large amount of nitrogen. | Materials Science Forum | [

Genomic islands of differentiation between house mouse subspecies | Understanding the genes that contribute to reproductive isolation is essential to understanding speciation, but isolating such genes has proven very difficult. In this study I apply a multilocus test statistic to >10,000 SNP markers assayed in wild-derived inbred strains of house mice to identify genomic regions of elevated differentiation between two subspecies of house mice, Mus musculus musculus and M. m. domesticus. Differentiation was high through ∼90% of the X chromosome. In addition, eight regions of high differentiation were identified on the autosomes, totaling 7.5% of the autosomal genome. Regions of high differentiation were confirmed by direct sequencing of samples collected from the wild. Some regions of elevated differentiation have an overrepresentation of genes with host–pathogen interactions and olfaction. The most strongly differentiated region on the X has previously been shown to fail to introgress across a hybrid zone between the two subspecies. This survey indicates autosomal regions that should also be examined for differential introgression across the hybrid zone, as containing potential genes causing hybrid unfitness. | [

Early Outcomes of Endoscopic Papillary Muscle Relocation for Secondary Mitral Regurgitation Type IIIb in Patients With Severe Left Ventricular Dysfunction | Objective: Subannular mitral valve (MV) repair techniques have been developed to address increased rates of recurrent mitral regurgitation (MR) in patients with secondary MR (SMR) type IIIb. Endoscopic papillary muscle relocation (PMR) is feasible via minithoracotomy. Nevertheless, the periprocedural outcome of patients with severe left ventricular (LV) dysfunction remains unknown. Methods: A total of 98 consecutive patients with SMR type IIIb underwent PMR at our institution. Due to concomitant coronary artery bypass grafting, 62 patients underwent sternotomy and were excluded from the current analysis, whereas 36 patients were treated by a minimally invasive technique using 3-dimensional endoscopy. Of these, 18 patients had severely depressed LV ejection fraction (LVEF) ≤35% (study group) and were compared to the remaining 18 patients with LVEF >35% (control group). Periprocedural outcome was retrospectively analyzed. Results: Although LVEF was significantly worse in the study group (30% ± 4% vs 43% ± 6%, P | [

Exercise intolerance in post-COVID19 survivors after hospitalization | RationalePost-COVID19 survivors frequently have dyspnea that can lead to exercise intolerance and lower quality of life. Despite recent advances, the pathophysiological mechanisms of exercise intolerance in the post-COVID19 patients remain incompletely characterized.ObjectivesTo clarify the mechanisms of exercise intolerance in post-COVID19 survivors after hospitalization.MethodsProspective study evaluated consecutive patients previously hospitalized due to moderate-to-severe/critical COVID19. Within 90±10 days (mean±sd) of COVID19 acute symptoms onset, patients underwent a comprehensive cardiopulmonary assessment, including a cardiopulmonary exercise testing with earlobe arterialized capillary blood gas analysis.Measurements and Main ResultsEighty-seven patients were evaluated, their mean±sdpeak oxygen consumption were 19.5±5.0 ml kg−1·min−1, and the tertiles were: ≤17.0, 17.1–22.2 and ≥22.3 ml kg−1·min−1. Hospitalization severity was similar among the three groups; however, at the follow-up visit, they reported a greater sensation of dyspnea, along with indices of impaired pulmonary function, and abnormal ventilatory, gas-exchange and metabolic responses during exercise compared to patients with peak oxygen consumption >17 ml kg−1·min−1. By multivariate logistic regression analysis (ROC curve analysis) adjusted for age, sex and pulmonary embolism, a peak dead space fraction of tidal volume ≥29 and a resting forced vital capacity ≤80%predicted were independent predictors of reduced peak oxygen consumption.ConclusionsExercise intolerance in the post-COVID19 survivors was related to a high dead space fraction of tidal volume at peak exercise and a decreased resting forced vital capacity, suggesting that both pulmonary microcirculation injury and ventilatory impairment could influence aerobic capacity in this patient population. | [

“Mi escuela es como…” análisis de metáforas del profesorado principiante | RESUMEN En este artículo analizamos las concepciones que docentes principiantes de un programa de inducción tienen sobre la escuela. Hemos trabajado con 269 comentarios realizados en un foro donde han respondido a la afirmación: “Una escuela es como…”. Las metáforas obtenidas tras la codificación las hemos analizado localizando la imagen de escuela que proyectan a partir de la propuesta de Miles y Ekholms. Los resultados obtenidos indican que la concepción de escuela predominante se relaciona con su caracterización con una imagen racional, centrada en resultados. La mayoría percibe su lugar de trabajo como una organización encaminada hacia la consecución de metas específicas preestablecidas. Son escasas las referencias a la imagen política como espacio caracterizado por el enfrentamiento y el poder. | [

Modeling Calculation of the Corrosion Rate of Low Carbon Steel in Heat and Power Systems | This article is about electrochemical analysis system of passive films corrosion properties of the thermal power equipment heating surfaces. It was found that forecasting the low carbon steel corrosion rate in thermal power systems is possible based on the multiple regression equations, which includes the amount of silicon oxide and iron hydroxide phases in the films, the fraction of free area and the active component of impedance of the films in the alkaline electrolyte and mercury. Construction of the regression equation should be carried out with the preliminary classification of data on the quantities of the active component of the film impedance of mercury and an alkaline electrolyte. | [

Abstract PS6-42: Prognostic value of neutrophil to lymphocyte ratio in patients with breast cancer in a Mexican population | Abstract Background: Inflammatory serum markers (IBM) have emerged as prognostic factors in solid tumors. In breast cancer (BC) in particular, an elevated neutrophil to lymphocyte ratio (NLR) has been linked to lower overall survival (OS) and disease-free survival (DFS), although a standard cutoff value has not been established. In Mexico there is no information regarding NLR as a prognostic marker in BC. The aim of the present study was to assess NLR as prognostic factor in BC patients in a Mexican population. Methods: This single-center retrospective and descriptive study included patients, >18 years old with histological diagnosis of BC who were treated at Medica Sur oncological center in Mexico City between January 2008 and December 2019. The patients were divided into two groups according to their NLR. NLR was calculated using the following formula: absolute neutrophil count / absolute lymphocyte count (mm3). NLR was considered as elevated (>2), and as low (≤2) based on data from previous studies. The primary endpoint was OS. Statistical analysis was performed with SPSS v25. The associations between PNI and clinicopathologic characteristics were analyzed using Pearson's χ2 test. Kaplan-Meier and log-rank test methods were used for survival analysis. The prognostic value of the pre-treatment NLR was assessed by univariate and multivariate analysis. P<0.05 was considered to indicate a statistically significant difference. This study was approved by our scientific and bioethical committee. Results: A total of 110 patients were included in the final analysis. All patients had infiltrating ductal carcinoma; 18.2% were triple negative, 23.6% over-expressed HER 2 and around 51% had hormone receptor expression. 15.5% had metastatic disease. Median follow-up was 65 months. Mean NLR at diagnosis was 2.82 (SD 2.59). Mean NLR in patients with triple negative BC (TNBC) was significantly higher than in patients with non TNBC (p= 0.055), no other statistically significant associations were found between mean NLR and clinical characteristics. Median OS was not reached in two groups, but the 100 months OS was higher in NLR ≤2 group vs NLR > 2 group (90 vs 78%) (p= 0.079). In univariate and multivariate analysis, triple negative histological subtype and elevated NLR were independent prognostic indicators of poor survival. Conclusion: An elevated pretreatment NLR was an independent prognostic factor, associated with lower OS in patients with BC with local and advanced disease, although statistically significant association was not found. NLR is an accessible and minimally invasive marker with clinical value for evaluation of the prognosis of BC patients, especially in resource-limited settings.

Genomic signature of sexual reproduction in the bdelloid rotifer Macrotrachella quadricornifera | Abstract Bdelloid rotifers, common freshwater invertebrates of ancient origin and worldwide distribution have long been thought to be entirely asexual, being the principal exception to the view that in eukaryotes the loss of sex leads to early extinction. That bdelloids are facultatively sexual is shown by a study of allele sharing within a group of closely related bdelloids of the species Macrotrachella quadricornifera, supporting the view that sexual reproduction is essential for long-term success in all eukaryotes. | [

Caracterización de pigmentos históricos a través de técnicas de imagen, en diversas bandas del espectro electromagnético | El presente artículo propone una prueba de concepto para la observación mediante técnicas de imagen multibanda de 63 pigmentos de referencia histórica (usados desde la Antigüedad hasta el siglo XX). La respuesta de estos pigmentos se ha documentado en varios puntos de espectro mediante la construcción de sus imágenes, por reflexión, transmisión, luminiscencia y falso color, desde el visible (VIS) hacia sus dos extremos, ultravioleta (UV) e infrarrojo (IR), completando además el estudio con la imagen radiográfica (RX). Cada pigmento responde de manera diferente en cada una de las técnicas usadas, en función de su comportamiento espectral, lo que genera un patrón de conducta único para cada materia. El conjunto de técnicas utilizadas conforma una metodología que plantea 11 posibles formas de ver, entendiéndolas de manera aislada, si bien es en la lectura transversal y confrontación de todas ellas donde se alcanzan unos resultados más completos, a través de un método inductivo basado en la observación. Se trata de un estudio de carácter novedoso que, aunque cuenta con precedentes aislados, compendia por primera vez en forma de imágenes, el aludido comportamiento espectral de tales pigmentos. Así, los resultados obtenidos pretenden contribuir a la mejorar la lectura e interpretación de los análisis no invasivos por imagen aplicados a obras pictóricas, permitiendo la identificación preliminar de algunos pigmentos. | [

The Progressive Multilevel Embedding Method for Audio Steganography | Abstract Audio steganography refers to hiding a secret message inside a cover audio file. The existing methods follow almost a sequential embedding which leads to poor utilization of the cover. The proposed method aims to achieve the maximum feasible capacity of the audio file without lowering the quality. The proposed method is based on seven levels of thresholds and six LSB layers, while the embedding is carried out progressively. The method allocates the message bits over the cover signal horizontally to ensure fair payload distribution over the signal. Hence, the selected samples might be visited multiple times till the message is totally embedded. The experimental results show that the method is able to reach a hiding capacity of 40% of the file size or 266.6 kbps while maintaining an SNR and PSNR values of 40 and 58 dB respectively. It is concluded that the proposed progressive method is highly adaptive to the message size and capable of providing high-quality stego even when big payloads are used. The comparative study shows that the progressive method provides the best message distribution based on the nature of the cover. | [

Correction | The following corrections have been made to the article “The Hague Evidence Convention: Practice in the Netherlands”, written by E.P.A. Keyzer and M.T. Nijhuis (attorneys-at-law, Loeff & Van der Ploeg, Advocaten en Notarissen) and appearing in the last issue of the Leiden Journal of International Law (Vol. 2, No. 2, 1989).On page 162 of that issue two unrelated notes were put together (the two judgments of the Dutch Supreme Court have no bearing with the article of P. Herdenberger).On page 164, the second phrase (“Risks for Dutch parties in case they do not comply with dicovery orders”) should have been used to mark a new sub-paragraph and is not a phrase which fits within the article.On page 165, in sub-paragraph 4.3. the words “from the Communities” were mistakenly added to the phrase “In 1983 the N.V. Philips Gloeilampenfabriek (hereinafter ‘Philips’) in Eindhoven requested an exemption”. This addition did not appear in the original text and does not enhance the meaning of the text.We regret any inconvenience to our readers and extend our sincerest apologies.The Editorial Staff | [

On Free Bending Vibrations Of Concrete Beams With Variable Cross Section | The paper consists of an introduction and three sections. The introduction discusses the relevance of issues related to the study of inhomogeneous beams vibrations. The analysis of publications and the results obtained in this area is performed. The first section is devoted to the formulation of the boundary-value problem of finding natural-vibration frequencies for an inhomogeneous beam under the Euler-Bernoulli hypotheses. By introducing new variables, the problem originally formulated in displacements reduces to an identical one, but formulated in terms of bending moment. The next section describes the method of integro-differential relations, which is an alternative to the classical variational approaches. Further, the possibilities of constructing various bilateral energy estimates of the quality of approximate solutions arising from the method of integro-differential relations are investigated. In the third section, using the example of free vibrations of a supported concrete beam, numerical aspects of constructing an approximate solution for boundary problems described by an ordinary differential equation with variable coefficients are studied. The proposed bilateral quality criteria of the approximate solution make it possible to obtain high-precision solutions for mathematical models of small dimension. | [

Machine Learning Algorithm for Efficient Design of Separated Buffer Super-Junction IGBT | An improved structure for an Insulated Gate Bipolar Transistor (IGBT) with a separated buffer layer is presented in order to improve the trade-off between the turn-off loss (Eoff) and on-state voltage (Von). However, it is difficult to set efficient parameters due to the increase in the new buffer doping concentration variable. Therefore, a machine learning (ML) algorithm is proposed as a solution. Compared to the conventional Technology Computer-Aided Design (TCAD) simulation tool, it is demonstrated that incorporating the ML algorithm into the device analysis could make it possible to achieve high accuracy and significantly shorten the simulation time. Specifically, utilizing the ML algorithm could achieve coefficients of determination (R2) of Von and Eoff of 0.995 and 0.968, respectively. In addition, it enables the optimized design to fit the target characteristics. In this study, the structure proposed for the trade-off improvement was targeted to obtain the minimum Eoff at the same Von, especially by adjusting the concentration of the separated buffer. We could improve Eoff by 36.2% by optimizing the structure, which was expected to be improved by 24.7% using the ML approach. In another way, it is possible to inversely design four types of structures with characteristics close to the target characteristics (Eoff = 1.64 μJ, Von = 1.38 V). The proposed method of incorporating machine learning into device analysis is expected to be very strategic, especially for power electronics analysis (where the transistor size is comparatively large and requires significant computation). In summary, we improved the trade-off using a separated buffer, and ML enabled optimization and a more precise design, as well as reverse engineering. | Micromachines | [
