Published: February 2021

Background
People with atrial fibrillation (AF) have lower reported quality of life and increased risk of heart attack, death, and stroke. Lifestyle modifications can improve arrhythmia-free survival/symptom severity. Shared medical appointments (SMAs) have been effective at targeting lifestyle change in other chronic diseases and may be beneficial for patients with AF.

Objective
To determine if perceived self-management and satisfaction with provider communication differed between patients who participated in SMAs compared to patients in standard care. Secondary objectives were to examine differences between groups for knowledge about AF, symptom severity, and healthcare utilization.

Methods
We conducted a retrospective analysis of data collected where patients were assigned to either standard care (n = 62) or a SMA (n = 59). Surveys were administered at pre-procedure, 3, and 6 months.

Results
Perceived self-management was not significantly different at baseline (p = 0.95) or 6 months (p = 0.21). Patients in SMAs reported more knowledge gain at baseline (p = 0.01), and higher goal setting at 6 months (p = 0.0045). Symptom severity for both groups followed similar trends.

Conclusion
Patients with AF who participated in SMAs had similar perceived self-management, patient satisfaction with provider communication, symptom severity, and healthcare utilization with their counterparts, but had a statistically significant improvement in knowledge about their disease.

Background
Utility of the sentinel lymph node (SLN) biopsy in some malignancies has been reported, however, research on that of gallbladder cancer (GBC) is rare. The aim of this study is to investigate whether the concept of SLN is applicable to T2/3 GBC.

Methods
A total of 80 patients who underwent resection for gallbladder cancer were enrolled in this study. Patients with GBC were stratified into two groups based on the location of tumor, peritoneal-side (T2p or 3p) and hepatic-side (T2h or 3h) groups. We evaluated the relationship between cystic duct node (CDN) and downstream lymph node (LN) status. CDN was defined as a SLN in this study.

Results
Thirty-eight patients were classified into T2, including T2p (n = 18) and T2h (n = 20), and 42 patients into T3, including T3p (n = 22) andT3h (n = 20). The incidence of LN metastasis was significantly higher in hepatic-side than peritoneal-side in both T2 and T3 (P = 0.036 and 0.009, respectively). In T2, 14 T2p had negative CDN and downstream LN, however, three T2h had negative CDN and positive downstream LNs (defined as a skipped LN metastasis) (P = 0.043). In T3, patients with skipped LN metastasis were significantly higher in T3h (n = 11) than those in T3p (n = 2) (P<0.001). There was no recurrence of the local lymph node. Disease-free survival in the T2p and T3p were significantly better than those in the T2h and T3h (P = 0.005 and 0.025, respectively).

Conclusion
The concept of SLN can be applicable to T2p GBC, where the downstream LNs dissection can be omitted.

Published: February 2021

Abstract

Objectives
To assess the effectiveness of incorporating hygienic-dietary recommendations in laboratory reports in reducing the incidence of renal colic (RC). A study was performed to compare the incidence of RC in two groups of patients who had suffered at least a crystalluria event associated with the risk of urolithiasis. Recommendations were only incorporated in the laboratory reports of one group.

Methods
A retrospective observational study. The study sample was composed of patients who had at least an episode of crystalluria associated with a higher risk of urolithiasis. The laboratory reports of patients in Group A (n=1,115), treated in 2017, did not include any hygienic-dietary recommendations, whereas patients in Group B (n=1,692), treated in 2018, received hygienic-dietary recommendations through their laboratory reports. χ2 and Mann-Whitney U test were used to assess differences based on sex, age, and type of urinary crystals.

Results
The incidence of RC was 2.02 times higher in group A (2.24%) than in group B (1.12%). No significant differences were observed in the incidence of RC based on the type of urinary crystal. The incidence of RC was substantially higher in patients who suffered at least an event of crystalluria associated with a higher risk for urolithiasis as compared to the general population during the same period (0.46%, consistently with the incidence rates reported in the literature).

Conclusions
The incorporation of messages alerting on the risk of urolithiasis and the inclusion of hygienic-dietary recommendations in laboratory reports may be useful for reducing the incidence of RC.

Abstract
Discrimination of malignant and non-malignant cells of histopathologic specimens is a key step in cancer diagnostics. Hyperspectral Imaging (HSI) allows the acquisition of spectra in the visual and near-infrared range (500-1000nm). HSI can support the identification and classification of cancer cells using machine learning algorithms. In this work, we tested four classification methods on histopathological slides of esophageal adenocarcinoma. The best results were achieved with a Multi-Layer Perceptron. Sensitivity and F1-Score values of 90% were obtained.
Use of Electrical Impedance Spectroscopy to Distinguish Cancer from Normal Tissues with a Four Electrode Terminal Setup
Authors: Teixeira Viviane S. , Labitzky Vera , Schumacher Udo , Krautschneider Wolfgang 
Published: February 2021

Abstract
Cancer and normal tissues are visually different from each other, especially so in more advanced cancer stages. More important, they are not only visually contrasting, but if an electric field is applied to both tissue types and the frequency is varied in a wide range, it will be seen that the two tissue types in general have a spectral response divergent from each other and this has to do with the characteristics of cancer tissues in contrast to normal ones. In this work, Electrical Impedance Spectroscopy is applied to try to distinguish cancer from healthy tissues by means of their impedance spectrum using a four-electrode-terminal setup. The use of the fourterminal- setup setup is important to circumvent the impact of electrode polarization at frequencies below 1 kHz.

The influence of strut-connectors in coronary stents: A comparison of numerical simulations and μPIV measurements
Authors: Melzer Helena-Sophie , Ahrens Ralf , Guber Andreas E. , Dohse Jakob 
Published: February 2021

Abstract
This paper discusses the influence of different designs of strut-connectors of stents by numerical flow simulations and flow examinations using micro particle image velocimetry (μPIV). Many studies have shown that there is a correlation between the hemodynamics after stent implantation and the cause of biological responses like thrombosis and the in-stent restenosis. Recirculation areas may occur through a stent, which are considered to be the cause of these clinical complications. In this study, three different coronary stent designs are investigated and the hemodynamic effects from the different designs is presented. The study focuses on the design of the strut-connectors that connect two struts. Numerical simulations were performed to evaluate various flow features like recirculation zones, velocity profiles and wall shear stress (WSS) patterns. To verify the numerical results μPIVmeasurements were performed. It could be shown that the alignment in the main stream of the connectors influences the size and number of recirculation zones.

Published: February 2021

Abstract
Existence of mild solution for noninstantaneous impulsive fractional order integro-differential equations with local and nonlocal conditions in Banach space is established in this paper. Existence results with local and nonlocal conditions are obtained through operator semigroup theory using generalized Banach contraction theorem and Krasnoselskii’s fixed point theorem, respectively. Finally, illustrations are added to validate derived results.
Effects of Ti-bearing inclusions on intragranular ferrite nucleation
Authors: Qiu Yue , Chen Fuhao , Huang Bangfu , Wu Zhaoyang , Kong Hui 
Published: February 2021

Abstract
The effect of Ti-bearing inclusion characteristics, such as size and marginal composition, on intragranular ferrite (IGF) nucleation has been explored in single sample through SEM and EDS. It can be seen that Ti-bearing inclusions can induce IGF nucleation, and this nucleation ability was scaled by the number of its induced lathes. Statistical analysis suggested that this ability may be correlated with inclusion size, and independent of Ti2O3 content in inclusion. The former can be attributed to the classical theory of heterogeneous nucleation. The latter can be explained by the relationship between the diffusion quantity of Mn and its solubility in Ti2O3 based on the theory of an Mn-depletion zone. Moreover, a probabilistic feature was observed in the nucleation phenomenon which may be due to a small difference in formation energy between the ferrite side plate and the IGF. These results may be helpful to clarify the nature of oxide metallurgy of a Ti-bearing inclusion.

Authors: Murathan Ömer Faruk , Davut Kemal , Kilicli Volkan 
Published: February 2021

Abstract
In this study, the effect of austenitizing temperatures and low-temperature isothermal heat treatment (below martensite start temperature) on the microstructure and mechanical properties of AISI 9254 high silicon spring steel has been investigated. Experimental studies show that ultra-fine carbide-free bainite, tempered martensite and carbon enriched retained austenite could be observed in isothermally heat-treated samples where the as-received sample consisted of fine pearlite. A high tensile strength of ~2060 MPa, a total elongation of ~8 %, and absorbed energy of 105 J were achieved in a commercial high-Si steel by austempering below the Ms temperature. A good combination of strength and ductility has been obtained in prolonged austempering below the martensite start temperature (225 °C) from an austenitizing temperature of 870 °C.

Published: February 2021

Abstract
High quality tubular products are essential to the oil and gas industry. Quality control during their production focuses on the non-destructive detection of surface defects. The structured light technique is a candidate for the challenge to detect, monitor and evaluate such defects in real-time. In the present study the automatic processing of structured light measurements is performed and validated. The algorithm for the automatic analysis of inspection data has an advantage over current data evaluation methods based on individual assessments of operators.
Friction and wear properties of heavy load truck composite brake linings
Authors: Bayram Emre , Topuz Ahmet 
Published: February 2021

Abstract
Materials for friction used in brakes should fulfill many requirements, such as stable friction performance in all conditions, lower change in the friction coefficient, high wear resistance and low wear rate. In this study, three different compositions were produced to investigate the effects of each composition and its manufacturing parameters. Three different compositions, which are called standard, fly ash and sisal fiber mixture, were produced to be compared with existing commercial heavy-duty truck brake lining. These compositions were homogeneously mixed and hot molded at different pressures and temperatures. The post-curing effect was also investigated in some of the samples. The wear and friction tests were performed using a friction tester. The density and hardness of the samples were also analyzed in relation to compositions and manufacturing parameters. The coefficient of friction and wear behavior was compared with a commercial heavy-duty truck brake lining. The results suggest that there is a high potential in the samples investigated for commercial trucks applications of brake lining products that are highly suitable from the environmental and cost reduction view.
A novel graphene-based Fe3O4 nanocomposite for magnetic particle inspection
Authors: Zhang Zhongqiang , Lu Leijun , Yi Yipin 
Published: February 2021

Abstract
The magnetic particle material is the crucial part in the field of nondestructive inspection. Nevertheless, traditional magnetic particle still leaves much to be desired. In this research, we designed a simple procedure to synthesize a novel graphene-based ferroferric oxide (Fe3O4) nanocomposite. All characterizations implied that Fe3O4 was anchored on the surface of reduced graphene oxide (RGO) nanosheets successfully. Especially this specimen reveals significant magnetic property improvement and macroscopic stability because of the synergistic effect between Fe3O4 and graphene, as compared to the traditional magnetic particle. More importantly, our method optimizes intrinsic magnetization intensity, reduces remanence and sedimentation velocity of magnetic particle material. Thus, this nanocomposite holds great potential for the field of magnetic particle inspection.

Published: February 2021

Abstract
A collection of 141 bone and antler tools and debitage pieces recovered from the River Užava at the village of Sise constitutes the largest Mesolithic osseous assemblage in western Latvia. Radiocarbon dating of 12 pieces suggests that most of this collection dates from the 6th millennium calBC. We present a general analysis, highlighting typical and unique tool forms, ornamented and sculpted pieces, and assess the corpus in a wider geographical context.
Predominant in this rich and diverse collection are heavy duty antler tools: various forms of adzes, axes and hammers as well as sleeves, made either from shed antler or antler of hunted animals. They include two pieces classifiable as T-axes. Spear- and arrowheads as well as daggers are also present, along with chisels, wedges, awls and other tools. Artistic representations include five sculpted and engraved objects.
The heavy duty red deer antler tools have parallels in the region south of the Baltic Sea, whereas the bone projectile forms are familiar from Kunda and Narva Culture sites of the East Baltic; the closest similarity is with osseous assemblages from coastal western Lithuania.

Teoría estética. La resurrección del arte
Authors: SILVIA ANDRELI DÍAZ NAVARRO LUIS GABRIEL MATEO MEJÍA 
Published: February 2021

Resumen: Si la teoría estética fue considerada hace años como una crítica de vanguardia ante los movimientos culturales y artísticos, fue debido a la importancia de sus análisis y razonamientos. Posteriormente, la teoría estética ha pasado a segundo plano debido a las severas críticas de la filosofía postmodernista, razón por la cual, se hace necesario retomar el proyecto de una filosofía del arte. En este caso, se habla de una estética analógica.

Presentación. Teorías Críticas del Neoliberalismo
Authors: Prestifilippo Agustín Lucas 
Published: February 2021

En un diálogo que tuvo sitio recientemente en la ciudad de Lyon, Nancy Fraser y Luc Boltanski (2016) se formularon la siguiente pregunta: ¿cuál es el objeto de la actual Teoría Crítica de la Sociedad? Si de lo que se trata es de ofrecer medios conceptuales a las luchas sociales de nuestro tiempo, esto es: si queremos comprender el rostro que asume el sistema de explotación y dominación social contemporánea, inevitablemente nos topamos con la realidad del neoliberalismo. Pero al identificar nuestro presente como un tiempo signado por la forma social neoliberal, ¿no se pierde de vista su inscripción esencial en el patrón de acumulación capitalista?
Los textos que componen este dossier presentan lecturas que se mueven alrededor de la inevitabilidad de este debate, toda vez que el pensamiento radical del siglo XXI no desiste de ofrecer una correcta caracterización de nuestro mundo social.
