Inherited and Acquired Rhythm Disturbances in Sick Sinus Syndrome, Brugada Syndrome, and Atrial Fibrillation: Lessons from Preclinical Modeling

Rhythm disturbances are life-threatening cardiovascular diseases, accounting for many deaths annually worldwide. Abnormal electrical activity might arise in a structurally normal heart in response to specific triggers or as a consequence of cardiac tissue alterations, in both cases with catastrophic consequences on heart global functioning. Preclinical modeling by recapitulating human pathophysiology of rhythm disturbances is fundamental to increase the comprehension of these diseases and propose effective strategies for their prevention, diagnosis, and clinical management. In silico, in vivo, and in vitro models found variable application to dissect many congenital and acquired rhythm disturbances. In the copious list of rhythm disturbances, diseases of the conduction system, as sick sinus syndrome, Brugada syndrome, and atrial fibrillation, have found extensive preclinical modeling. In addition, the electrical remodeling as a result of other cardiovascular diseases has also been investigated in models of hypertrophic cardiomyopathy, cardiac fibrosis, as well as arrhythmias induced by other non-cardiac pathologies, stress, and drug cardiotoxicity. This review aims to offer a critical overview on the effective ability of in silico bioinformatic tools, in vivo animal studies, in vitro models to provide insights on human heart rhythm pathophysiology in case of sick sinus syndrome, Brugada syndrome, and atrial fibrillation and advance their safe and successful translation into the cardiology arena.
Disclosure Style and Its Determinants in Integrated Reports

Integrated Reporting promotes a more cohesive and efficient approach to corporate reporting and aims to improve the quality of information available to providers of financial capital. The purpose of this paper was to investigate the determinants of readability and optimism which build the disclosure style of integrated reports. Our research draws on impression management theory and legitimacy theory, while also taking into consideration the cultural system of Hofstede with its further developments by Gray. Our sample consisted of 30 annual reports, extracted randomly from the Integrated Reporting examples database set up by the International Integrated Reporting Council. For the purposes of our investigation, we have carried out a multivariate regression analysis. Firstly, our results show that the higher the revenues of the reporting company, the more balanced their integrated reports, while younger companies use a more optimistic tone when reporting. Additionally, optimism seems to be inversely correlated with the length of the reports. Secondly, entities based in countries with a stronger tendency towards transparency surprisingly provide less readable integrated reports. It was also revealed that companies operating in non-environmentally sensitive industries, as well as International Financial Reporting Standards adopters deliver foggier and thus less readable integrated reports.
Cometary evolution : clues on physical properties from chondritic interplanetary dust particles

The degree of diversity or similarity detected in comets depends primarily on the lifetimes of the individual cometary nuclei at the time of analysis. It is inherent in our understanding of cometary orbital dynamics and the seminal model of comet origins that cometary evolution is the natural order of events in our Solar System. Thus, predictions of cometary behaviour in terms of bulk physical, mineralogical or chemical parameters should contain an appreciation of temporal variation(s). Previously, Rietmeijer and Mackinnon [1987] developed mineralogical bases for the chemical evolution of cometary nuclei primarily with regard to the predominantly silicate fraction of comet nuclei. We suggested that alteration of solids in cometary nuclei should be expected and that indications of likely reactants and products can be derived from judicious comparison with terrestrial diagenetic environments which include hydrocryogenic and low-temperature aqueous alterations. In a further development of this concept, Rietmeijer [1988] provides indirect evidence for the formation of sulfides and oxides in comet nuclei. Furthermore, Rietmeijer [1988] noted that timescales for hydrocryogenic and low-temperature reactions involving liquid water are probably adequate for relatively mature comets, e.g. P/comet Halley. In this paper, we will address the evolution of comet nuclei physical parameters such as solid particle grain size, porosity and density. In natural environments, chemical evolution (e.g. mineral reactions) is often accompanied by changes in physical properties. These concurrent changes are well-documented in the terrestrial geological literature, especially in studies of sediment diagenesis and we suggest that similar basic principles apply within the upper few meters of active comet nuclei. The database for prediction of comet nuclei physical parameters is, in principle, the same as used for the proposition of chemical evolution. We use detailed mineralogical studies of chondritic interplanetary dust particles (IDPS) as a guide to the likely constitution of mature comets traversing the inner Solar System. While there is, as yet, no direct proof that a specific sub-group or type of chondritic IDP is derived from a specific comet, it is clear that these particles are extraterrestrial in origin and that a certain portion of the interplanetary flux received by the Earth is cometary in origin. Two chondritic porous (CP) IDPS, sample numbers W701OA2 and W7029CI, from the Johnson Space Center Cosmic Dust Collection have been selected for this study of putative cometary physical parameters. This particular type of particle is considered a likely candidate for a cometary origin on the basis of mineralogy, bulk composition and morphology. While many IDPs have been subjected to intensive study over the past decade, we can develop a physical parameter model on only these two CP IDPs because few others have been studied in sufficient detail.
Pathogenesis and Clinical Significance of In-Stent Restenosis in Patients with Diabetes

Diabetes mellitus (DM) is a strong risk factor for the development of cardiovascular diseases such as coronary heart disease, cerebrovascular disease, and peripheral arterial disease (PAD). In the population of people living with DM, PAD is characterised by multi-level atherosclerotic lesions as well as greater involvement of the arteries below the knee. DM is also a factor that significantly increases the risk of lower limb amputation. Percutaneous balloon angioplasty with or without stent implantation is an important method of the treatment for atherosclerotic cardiovascular diseases, but restenosis is a factor limiting its long-term effectiveness. The pathogenesis of atherosclerosis in the course of DM differs slightly from that in the general population. In the population of people living with DM, more attention is drawn to such factors as inflammation, endothelial dysfunction, platelet dysfunction, blood rheological properties, hypercoagulability, and additional factors stimulating vascular smooth muscle cell proliferation. DM is a risk factor for restenosis. The purpose of this paper is to provide a review of the literature and to present the most important information on the current state of knowledge on mechanisms and the clinical significance of restenosis and in-stent restenosis in patients with DM, especially in association with the endovascular treatment of PAD. The role of such processes as inflammation, neointimal hyperplasia and neoatherosclerosis, allergy, resistance to antimitotic drugs used for coating stents and balloons, genetic factors, and technical and mechanical factors are discussed. The information on restenosis collected in this publication may be helpful in planning further research in this field, which may contribute to the formulation of more and more precise recommendations for the clinical practice.
Diversity, Intent, and Aggregated Search

Diversity, intent and aggregated search are three core retrieval concepts that receive significant attention. In search result diversification one typically considers the relevance of a document in light of other retrieved documents. The goal is to identify the probable "aspects" of an ambiguous query, retrieve documents for each of these aspects and make the search results more diverse. By doing so, in the absence of any knowledge of users' context or preferences, the chance that the user will find at least one of these results to be relevant to their underlying information need is increased. Those probable "aspects" of a query may refer to lexical ambiguity (e.g., flash -- Adobe Flash, flash light, flash gordon, flash airlines, flash mob,.) or to intentional ambiguity (e.g., pizza -- how to make one, where to buy one, images, nutritional value, background, restaurant,.). The automatic discovery of query intent has become an active research area, with a range of observational and algorithmic studies as outcomes. Understanding the likely intents behind a query can help search engines to automatically route the query to the corresponding vertical search engines so as to obtain particularly relevant results, thus greatly improving user satisfaction. In aggregated search the task is to search and assemble information from a variety of sources and to organize the resulting material within a single interface. The result page of a modern search engine often goes beyond a simple ranked list. Many specific intents are addressed by aggregated search solutions: specially presented documents, often retrieved from specific sources, that stand out from the regular organic search results.
Does the Institutional Context Shape International Operations Strategy? Country-Level Analysis

Recent literature has proposed that institutions play a pivotal role in corporate and business strategies. We argue that this role holds for manufacturing strategy as well. Despite extensive literature regarding international operations management (OM), few studies verify how important variables in OM vary across different institutional contexts. This scarcity of comparative crosscountry research reveals an important gap both for research and practice. In this paper we address this gap by providing a data analysis of a recent survey collected in Canada and Brazil. We replicate and extend previous research by comparing important variables of manufacturing strategy in these two institutional contexts such as knowledge exchange, green process management, environmental supplier management and the traditional manufacturing performance dimensions.

Space/Interface Charge Analysis of the Multi-Layer Oil Gap and Oil Impregnated Pressboard Under the Electrical-Thermal Combined Stress

In oil-paper insulation systems, it is easy to accumulate space/interface charge under a direct current (DC) electrical field. At present, direct measurement of space/interface charge for a thick multi-layer insulation system is not possible. It is necessary to study the multi-layer oil-paper insulation system via simulation method. In this paper, the space/interface charge simulation based on the bipolar charge transport model and a simulation parameter using FEM for the multi-layer oil–paper insulation system was proposed. The influence of electrical field strength, temperature, and the combined influence of the electrical field strength and temperature on the space/interface charge behaviors were analyzed, respectively. A new method for calculating the space/interface charge density and the total charge quantity of the multi-layer oil-paper insulation under the combined action of electrical field strength and temperature was presented. Results show that the interface charge density absolute value and the total charge quantity at steady state both increases with the electrical field strength and temperature in an exponential way, respectively. Besides, temperature has a more significant influence on the charge density and the total charge quantity than the electrical field strength. The electrical field strength–temperature shifting factor αT’ was introduced for the translation of the charge density curves or the total charge quantity curves to construct the charge density main curve or the total charge quantity main curve under the combined action of electrical field strength and temperature. The equations for calculating the charge density or the total charge quantity of the multi-layer oil-paper insulation was provided, which could be used to calculate the charge density or the total charge quantity under the combined action of electrical field strength and temperature.

Estimating Min-Entropy Using Probabilistic Graphical Models

This paper presents a method for using probabilistic graphical models to discover dependency rela­ tionships among the bit positions in a sample of multi-bit blocks of binary data. Since it is computation­ ally infeasible to exhaustively test for all possible dependency combinations, a heuristic is needed. We use Bayesian networks to represent possible dependence structures and a genetic algorithm to evolve in­ creasingly better-scoring Bayesian networks that best identify the statistical dependencies in the sample. A technique for graphical models is used to estimate the min-entropy of the unknown underlying joint probability distribution based on the best-scoring Bayesian network. This method has shown success for block sizes of several dozen bits, where the output spaces cannot be easily decomposed into smaller spaces for independent analysis. Future optimizations may allow for analysis of even larger block-size entropy sources
Characteristic features of the electronic structure of copper oxide (CuO): Initiation of the polar configuration phase and middle-IR optical absorption

A model for the initiation of the polar-center phase (variable valence phase) is proposed in order to explain the characteristic features of the electronic structure and a number of physical properties of copper oxide (Cu0)-the basic model object for studying high-T, superconducting materials. The nuclei of the new phase consist of a system of electron and hole Jahn-Teller centers-CUO:and CUO:clusters, respectively. The optical signatures of the nuclei are absorption bands in the middle-IR range as well as new lines in the Raman light-scattering spectrum. The spectral, polarization, and temperature dependence of the absorption of CuO single crystals in the range 0.1-1.0 eV was studied experimentally. The two absorption bands observed at 0.1 and 0.2 eV are associated with transitions in singlet hole centers. The proposed model gives a unified description of the characteristic features of CuO spectra in the middle-IR range, the Raman scattering spectra, and the characteristic features of the temperature dependence of the electric conductivity and magnetic susceptibility.
Comparative Study of Printed Multilayer OLED Fabrication through Slot Die Coating, Gravure and Inkjet Printing, and Their Combination

In this study, multilayer organic light-emitting diodes (OLEDs) consisting of three solution-processed layers are fabricated using slot die coating, gravure printing, and inkjet printing, techniques that are commonly used in the industry. Different technique combinations are investigated to successively deposit a hole injection layer (poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS)), a cross-linkable hole transport layer (N,N′-bis(4-(6-((3-ethyloxetan-3-yl)methoxy)-hexyloxy)phenyl)-N,N′-bis(4-methoxyphenyl)biphenyl-4,4′-diamin (QUPD)), and a green emissive layer (TSG-M) on top of each other. In order to compare the application techniques, the ink formulations have to be adapted to the respective process requirements. First, the influence of the application technique on the layer homogeneity of the different materials is investigated. Large area thickness measurements of the layers based on imaging color reflectometry (ICR) are used to compare the application techniques regarding the layer homogeneity and reproducible film thickness. The total stack thickness of all solution-processed layers of 32 OLEDs could be reproduced homogeneously in a process window of 30 nm for the technique combination of slot die coating and inkjet printing. The best efficiency of 13.3 cd A−1 is reached for a process combination of slot die coating and gravure printing. In order to enable a statistically significant evaluation, in total, 96 OLEDs were analyzed and the corresponding 288 layers were measured successively to determine the influence of layer homogeneity on device performance.
RF-Eletter: A cross-domain English letter recognition system based on RFID

As the basis of human-computer interaction (HCI), gesture recognition interprets user-performed gestures as commands, followed by the content execution expressed by users’ gestures. Gesture recognition through wireless signals denotes a novel branch of human perception. Despite the recent popularity of Radio Frequency Identification (RFID) following specific advantages (lightweight, low-cost, and universality), several intricacies remain unresolved in RFID sensing research. First, most studies performed simplified body movements assessments instead of identifying complex and fine-grained or subtle gestures. Second, users require extensive training in a novel discipline to collect training data in a specific pattern. Given the paucity of an intuitive and effective means of identifying user gestures, the RF-E-letter proposed in this study denotes an RFID recognition system for complex, fine-grained, and domain-independent gestures. A multi-label array was utilized to gather gesture signals. Fine-grained gesture data could be obtained pre-processing with a novel data-processing method. Seemingly irregular RFID phase data could be converted into intuitive images for the deep learning module input as convolutional neural networks (CNNs) encompass automatic extraction characteristics for complex space-time features. The average accuracy of new environments for novel users is 95.6% and 96.6%, respectively (significantly better than current RFID-based solutions), thus demonstrating effectiveness and versatility.
Selective oxidation of excess amorphous carbon during single-walled carbon nanotubes synthesis by induction thermal plasma process

The induction thermal plasma process has been employed for the production of high quality and moderate pure single-walled carbon nanotubes, SWCNTs, (i.e. purity of ~ 40 wt. %). An effort has been made to improve the purity of SWCNTs materials during their production (i.e. an in situ purification process). Thermal oxidation process could help to remove most of amorphous carbon (a-C) impurities from the final SWCNT product resulting an increment of SWCNT purity from ~ 40 wt% to ~ 60 wt%.
Effect of Temperature on Laminar Flame Velocity for Hydrogen-Air Mixtures at Reduced Pressures

The work was done with respect to hydrogen safety of ITER vacuum vessel in cases of loss of cooling and loss of vacuum accidents. Experiments were conducted at sub-atmospheric pressures from 1 bar to 200 mbar and elevated temperatures up to 300 C. Hydrogen concentration was changed from lower to upper flammability limits in all the range of pressures and temperatures. The experiments were performed in a spherical explosion bomb equipped with two quartz windows. The flame propagation velocity was measured using pressure method and high speed shadow cinematography. The theoretical flame velocities were calculated by Cantera code using Lutz and Mueller mechanisms. The influence of the initial temperature and pressure conditions on the laminar flame speed SL, overall reaction order n and Markstein length LM are presented in this work and compared with the results of a theoretical model.
The Existence and Global Exponential Stability of Almost Periodic Solutions for Neutral-Type CNNs on Time Scales

In this paper, neutral-type competitive neural networks with mixed time-varying delays and leakage delays on time scales are proposed. Based on the contraction fixed-point theorem, some sufficient conditions that are independent of the backwards graininess function of the time scale are obtained for the existence and global exponential stability of almost periodic solutions of neural networks under consideration. The results obtained are brand new, indicating that the continuous time and discrete-time conditions of the network share the same dynamic behavior. Finally, two examples are given to illustrate the validity of the results obtained.

Knochenumbaurate vier verschiedener Implantatoberflächen in regionalem Knochen mittels Polyfluorochrom-Markierung in Beagle Hunden

Diese in vivo Studie analysiert vier Implantatoberflächen. Es wurden jeweils vier unterschiedliche TitanSchrauben-Implantate (Branemark MK III, Osseotite, Xive und Compress) mit vier unterschiedlichen Oberflächen (TiUnite, Osseotite, Friadent Plus und maschiniert/sandgestrahlt) im Unterkiefer von zwölf Beagle Hunden inseriert. Intravitale Fluorochrom-Färbung wurde in der 1. (Alizarin), 2. –3. (Calceingrün) und 4. –5. (Xylenolorange) Woche durchgeführt. Fünf Tiere wurden nach sechs Wochen, die verbleibenden sechs Tiere nach zwölf Wochen histologisch und histomorphometrisch analysiert. Nach sechs Wochen Einheilzeit konnte kein statistisch signifikanter Unterschied zwischen den vier untersuchten Implantatoberflächen sowohl hinsichtlich der analysierten peri-implantären (% der markierten Knochenoberfläche: Xive (73,38 % ± 10, 3%), Branemark (69,97 % ± 25 %), Compress (54,47 % ± 17,5 %) und Osseotite (49,53 % ± 9,5 %)) Knochenregenerationsrate als auch bezüglich der resultierenden BIC gezeigt werden. Der einzige signifikante Unterschied in der Knochenregenerationsrate konnte in der 12-Wochen-Gruppe für das Compress vs. Branemark Implantat gezeigt werden (sign test, p = 0,03; alle anderen sign tests p > 0,063). Zu diesem Zeitpunkt fand sich in Analyse der Knochen-Implantat-Kontakt-Rate (BIC) (Xive 72,36 % ± 8,21 %, Branemark 53,37 % ± 9,74 %, Osseotite 47,47 % ± 11,95 % und Compress 42,7 % ± 5,7%)) kein statistisch signifikanter Unterschied (Vorzeichentest, alle p ≥ 0,063). Diese Studie unterstützt die These, dass der Effekt der untersuchten Implantatoberflächen auf die peri-implantäre Knochenregeneration und BIC sich nicht in statistisch signifikantem Umfang unterscheidet.
