A Fault Diagnosis Method of Train Wheelset Rolling Bearing Combined with Improved LMD and FK

Trackside acoustic signals contain intense noise and nonstationary features even after Doppler distortion correction. Information on bearing defects in these signals is either weak or heavily attenuated. Thus, an improved compound interpolation envelope local mean decomposition (ICIE LMD) method combined with a fast kurtogram (FK) is proposed for wheelset bearings. In this methodology, cubic Hermite interpolation and cubic spline interpolation are employed to find the envelope of the extremal points in the ICIE LMD algorithm to improve accuracy and decrease the computing time of the decomposed signal component. An FK is sensitive to the impact signal and extracts the fault impact features efficiently. In the application, the proposed method uses ICIE LMD to decompose the multicomponent signal into several specific single product function (PF) components. The kurtosis index of the PF is calculated to select the component which contains the most fault information. Then, the selected component of PF is filtered by FK. Finally, the squared envelope spectrum is used to obtain the fault frequency and identify the fault location. The advantages of the ICIE LMD method are verified by simulation analysis. In the application, the results show that the proposed method efficiently extracts the fault features and enhances the target characteristics of the sound signals from a trackside microphone array. Furthermore, the influence of rotating frequency on locating the fault is reduced.

Blockchain Technology and Law (questions of theory and practice)

This article is devoted to the analysis of the mechanisms of legal regulation of the Blockchain system, as one of the new directions of development of the world economy. The authors define all basic concepts used in the implementation of crypto-currency technologies, study the existing experience of regulation of the Blockchain system in certain foreign countries, as well as elements of responsibility and taxation of transactions and revenues received through Blockchain technologies. The aim: to study all the main elements of the Blockchain system in terms of modern legal approaches of the Russian Federation, as well as the basis of its legal regulation in world practice. Methods: formal-logical, comparative-legal (comparative), analysis, sociological. Results: Currently, the Blockchain system is actively developing both in general and in its individual directions. It is important to understand that attitudes towards this system are becoming increasingly positive in society, despite existing problems. The most promising, according to the authors, is the issue of production tokens with due legal formalization, as it is this form of the issue of crypto that solves the tasks of developing the economy of the state by means of attracting the necessary funds for the implementation of any project. At present, there is a need to develop common approaches and adopt international acts defining the foundations of the legal status and regime of circulation of crypto and the implementation of the Blockchain system, both at the national and international levels, which allow to ensure the proper level of security, both for States and for participants in these processes. Undoubtedly, in the future, certain registration of Blockchain projects will be required, which will ensure a proper level of transparency and as a consequence of the legality of these projects. Moreover, the mechanism of taxation not only of transactions with crypto, but in general of organizations implementing Blockchain technologies and receiving profit from it, as well as the issues of liability of these firms under the legislation of the Russian Federation and foreign countries are still unclear, which will not allow this system to develop successfully in the future.
On the political feasibility of climate change mitigation pathways: Is it too late to keep warming below 1.5°C?

Keeping global warming below 1.5°C is technically possible but is it politically feasible? Understanding political feasibility requires answering three questions: (a) “Feasibility of what? ,” (b) “Feasibility when and where? ,” and (c) “Feasibility for whom? ” In relation to the 1.5°C target, these questions translate into (a) identifying specific actions comprising the 1.5°C pathways; (b) assessing the economic and political costs of these actions in different socioeconomic and political contexts; and (c) assessing the economic and institutional capacity of relevant social actors to bear these costs. This view of political feasibility stresses costs and capacities in contrast to the prevailing focus on benefits and motivations which mistakes desirability for feasibility. The evidence on the political feasibility of required climate actions is not systematic, but clearly indicates that the costs of required actions are too high in relation to capacities to bear these costs in relevant contexts. In the future, costs may decline and capacities may increase which would reduce political constraints for at least some solutions. However, this is unlikely to happen in time to avoid a temperature overshoot. Further research should focus on exploring the “dynamic political feasibility space” constrained by costs and capacities in order to find more feasible pathways to climate stabilization.
Investigating Iron Metabolism in Subarachnoid Hemorrhage Patients

Subarachnoid hemorrhage (SAH) is a stroke characterized by bleeding into the subarachnoid space of the brain, typically resulting in high mortality rate. Delayed cerebral ischemia (DCI), characterized by vasospasms induced arterial constriction, occurs in roughly one third of the surviving patients. The development of DCI and neurodegeneration could be linked to metabolic pathology that occurs after SAH, specifically iron induced changes in redox status. The oxidized environment induced by iron has the potential to functionally affect the ferroxidase ceruloplasmin (Cp), which is linked to neurodegeneration. Global LC-MS based metabolomics data revealed alterations in metabolism in the CSF at early and late timepoints after SAH as compared to controls. Early phase SAH and late phase SAH patients showed metabolic differences, however there was limited statistical significance. Specifically, the heme degradation product bilirubin (BR) and the glycolysis intermediate 3-phosphoglyceric acid were tentatively found to be down regulated in SAH. Iron toxicity was analyzed in a hemin induced model using differentiated SHSY5Y human neuroblastomas, revealing concentration-dependent cell killing and morphological changes. This data will be used as a baseline in future studies attempting to reverse iron toxicity via Cp treatment.
Scotland's Rural College Positioning smallholder farmers in the dairy innovation system in Malawi: a perspective of actors and their roles Chindime, S; Kibwika, P; Chagunda, MGG

7 The preference of an innovation systems approach to development is based on its inclusiveness and 8 interactions of the actors to co-influence each other to learn and innovate to bring about tangible 9 benefits. As more actors with diverse interests engage, the innovation system becomes more complex 10 and actors with higher influence power are likely to benefit more. Smallholder farmers in developing 11 countries are the core actors of an agricultural innovation system but their ability to influence other 12 actors to maximize their benefits is contentious. This paper applies a historical analysis of the 13 progressive development and complexity of Malawi’s diary innovation system through phased 14 emphasis on technological, organizational and institutional development to illustrate the centrality of 15 smallholder dairy farmers in the innovation system. A social network analysis is applied to assess the 16 influence of smallholder farmers on other actors. The existence and growth of the diary innovation 17 system in Malawi is founded on the resilience of smallholder dairy farmers to produce milk. Whereas 18 the smallholder farmers are the most connected in terms of interaction, they have the least influence on 19 other actors in the innovation system. To take advantage of their central position to maximize benefits, 20 smallholder farmers can only rely on their collective power to influence other actors. Organizing 21 farmers in groups and associations is a step in the right direction, but deliberate interventions by 22 innovation brokers as intermediaries needs to focus on empowering these groups. 23
Look Who's Tracking – An analysis of the 500 websites most-visited by Finnish web users

Though research into online tracking prevalence as a topic is not new, we still know little about who is tracking and profiling Finnish web users. This study examines tracking on the 500 websites most frequently visited by Finnish users. We also compare trackers on Finnish websites versus non-Finnish websites. We found trackers on 410 of the 500 websites, and a total of 466 unique trackers from 408 different organizations. Similar to most previous studies, Google had the greatest tracker coverage, mostly through Google Analytics and Doubleclick, reaching 75 % of the websites analyzed. The second-most prevalent tracking organization was Facebook, present on 46 % of the websites. After Google and Facebook came a number of organizations with fairly similar tracking coverage, followed by a long tail of others. There were notable differences when comparing Finnish websites to non-Finnish sites, displaying some level of geographical preference in publishers’ choices of advertising platforms and analytical tools.
Effect of food deprivation on neuropeptide Y immunoreactivity and concurrent biochemical and gonadal responses in tilapia Oreochromis mossambicus

The effect of short and long term fasting on neuropeptide Y (NPY) secreting neurons in the brain and concurrent biochemical and gonadal responses were determined in the cichlid fish Oreochromis mossambicus (Peters, 1852). Exposure of fish to fasting for 6 or 12 days resulted in intensely stained NPY-immunoreactive neurons in the nucleus entopeduncularis and the nucleus preopticus regions of the brain in contrast to moderately stained neurons in control fishes, whereas food supplementation after 6 days starvation restored NPY-immunoreactive profile to the same state as in control groups in both male and female fish. Gonadosomatic index (GSI) remained significantly lower in female fishes subjected to fasting alone as well as fasting followed by refeedings compared to controls. While the hepatosomatic index (HSI) also showed a significant decrease in fasting male and female fish compared to controls, it increased subsequently in fishes exposed to refeeding after starvation. In addition, a significant decrease in the serum levels of glucose and triglycerides as well as the hepatic tissue protein content in fasting fish compared to those of controls in both sexes suggested gluconeogenesis. Although the serum levels of glucose and triglycerides were reinstated in both male and female fishes subjected to starvation and refeeding. , the hepatic tissue protein levels were not completely restored in females. Collectively, these results suggest that fooddeprivation, either for short or long term duration, significantly increases the secretory activity of NPY neurons in the brain concomitant with a significant decrease in the serum levels of glucose and triglycerides, the hepatic tissue protein content and the GSI in both sexes. Although males recovered from the effects of starvation following refeeding, females appeared to be more vulnerable to the effects of fasting.
Effect of Electrolyte Additives on the LiNi0.5Mn0.3Co0.2O2 Surface Film Formation with Lithium and Graphite Negative Electrodes

The effect of various electrolyte additives (fluoroethylene carbonate (FEC), vinylene carbonate (VC), and propane sultone (PS)) on the performance of LiNi0.5Mn0. 3Co0.2O2 (NMC532) electrodes in combination with lithium (half‐cell) and graphite (full‐cell) negative electrodes, is herein reported. The cathode/electrolyte interface (CEI) layer formed on the NMC532 electrode cycled up to 4.5 V versus Li+/Li is investigated by X‐ray photoelectron spectroscopy and scanning electron microscopy. This allows correlating the electrochemical performance of the electrodes to the CEI chemical composition, thickness, and morphology. All the investigated electrolyte additives exhibit beneficial effects in half‐ and full‐cell systems, confirming the effective passivation layer formation protecting the electrolyte from further decomposition at high voltages. It is found that the thickness of the CEI layer forming on the NMC532 electrodes in half‐ and full‐cell configuration is different. VC and PS are found to be the best additives to enhance the performance mainly due to their positive contribution to the CEI formation. The solid/electrolyte interphase (SEI) formed on the graphite electrode is also investigated and compared to the CEI layer formed on the cathode. The detection of typical SEI reduction products on the positive electrode surface confirms the occurrence of cross‐talking between the two electrodes.
The Effect of Trade Liberalization on Indonesia's Exports

One of the open economic characteristics is the contribution of international trade in the economy. To make it bigger, there are many trade agreements are made to reduce international trade barriers. This study aims to determine the impact of trade liberalization on Indonesian exports to the three major trading partners in East Asia: South Korea, Japan, and China. The impact of liberalization on exports is examined using a gravity model and a panel with a period of 21 years (1996-2016). The independent variables used in this study are a tariff, degree of openness, population, exchange rate, GDP, and distance. The results of this study indicate that trade liberalization, viewed from the tariff and degree of openness has a significant effect on exports. Other influencing variables are GDP, population, and exchange rate. Distance variables have no effect on Indonesian exports to the three trading
Entanglement entropy and gravitational anomalies

Entanglement entropy is a fundamental quantity in Quantum Field Theory, characterizing the amount to which a system is entangled with its environment. For Conformal Field Theories (CFTs) with a holographic dual which is described by Einstein gravity, the entanglement entropy can be calculated using the celebrated Ryu-Takayanagi (RT) formula. However, the dual theory to a CFT with a gravitational anomaly is instead a higher derivative theory of gravity, known as Topologically Massive Gravity (TMG), so the RT procedure does not apply. An extension of the RT formula to TMG has recently been developed in [1] and there it was found that the entanglement entropy can be calculated using solutions of the so-called MPD equations, which describe spinning particles in classical General Relativity. We review this procedure and study the properties of the MPD equations in asymptotically AdS3 spacetimes. Perturbative solutions can be constructed in the limit when the spin s is small, but this perturbation breaks down when the interior of the spacetime is probed. We therefore examine the opposite limit: that of small mass m. We will look for perturbative solutions in this regime and outline a procedure to match the different solutions arising from these two limiting cases.
Relationship between overweight at 6 years of age and socioeconomic conditions at birth, breastfeeding, initial feeding practices and birth weight

ABSTRACT Objective To review the relationship between overweight at 6 years of age and socioeconomic conditions at birth, breastfeeding, early feeding practices and birth weight. Methods A cross-sectional study was carried out involving 473 six-year-old schoolchildren from public and private schools living in a municipality in Southern Brazil. Sociodemographic and breastfeeding data and other initial feeding practices were obtained through interviews with the mothers at home. Birth weight and gestational age were obtained from the child’s health card. Anthropometric data of the schoolchildren were collected during school visits. Bivariate and multivariate analyzes were performed using the Poisson Regression between the independent variables and overweight. Results The prevalence of overweight was 33.2%; 83.2% of the children were breastfed and out of these, 48.4% were breastfed only in the first six months. Non-breastfed children exhibited a 20% higher overweight prevalence (PR=1.20; 95%CI 1.13; 1.28). Children with exclusive breastfeeding for six months exhibited a lower overweight prevalence (PR=0.94; 95%CI 0.89; 0.99). Conclusion In this study, breastfeeding showed to be a protective factor for overweight.

Two technology-based addictions – internet gaming disorder (IGD) and social media addiction (SMA) – have been found to be related to comorbid disorders and impulsivity especially in adolescents and emerging adults’ populations, but results in this field are inconclusive Purpose: Using the latent profile analysis (LPA), this study identified different profiles of adolescents characterized by unique patterns of psychopathological risks, and similar levels of impulsivity, IGD, and SMA. Participants and methods: A total of 643 participants (312 males; Mage =16.02 years) were divided into three age groups (early, mid-, and late adolescence). They completed a battery of scales comprising: Internet Gaming Disorder Scale–Short Form, Bergen Social Media Addiction Scale, Barratt Impulsiveness Scale for Adolescents, and Symptom Checklist-90-R. Results: LPAs revealed distinct profiles across early, midand late adolescence with regards to the psychopathological variables taken into account. Specifically, only two profiles were identified in the 14–15 year age group, whereas three profiles emerged in the 16–17 year age group. Conclusion: This study highlighted that the profiles identified in each age group differed in terms of psychopathological risk (low, medium and high), showing instead similar (and nonclinical) scores in technology-based addictions and impulsivity. Results could be useful in designing prevention and intervention programs in youth showing similar patterns for technology-based addictions, but different levels of psychopathological symptoms.
OP-DNAR190013 327..340

Mycoplasmas are important model organisms for Systems and Synthetic Biology, and are pathogenic to a wide variety of species. Despite their relevance, many of the tools established for genome editing in other microorganisms are not available for Mycoplasmas. The Tn4001 transposon is the reference tool to work with these bacteria, but the transformation efficiencies (TEs) reported for the different species vary substantially. Here, we explore the mechanisms underlying these differences in four Mycoplasma species, Mycoplasma agalactiae, Mycoplasma feriruminatoris, Mycoplasma gallisepticum and Mycoplasma pneumoniae, selected for being representative members of each cluster of the Mycoplasma genus. We found that regulatory regions (RRs) driving the expression of the transposase and the antibiotic resistance marker have a major impact on the TEs. We then designed a synthetic RR termed SynMyco RR to control the expression of the key transposon vector elements. Using this synthetic RR, we were able to increase the TE for M. gallisepticum, M. feriruminatoris and M. agalactiae by 30-, 980and 1036-fold, respectively. Finally, to illustrate the potential of this new transposon, we performed the first essentiality study in M. agalactiae, basing our study on more than 199,000 genome insertions.
Risk Factors Associated with Spontaneous Abortion at Woman ' s Health Hospital Assiut University .

Background, Spontaneous abortion is a failed intrauterine pregnancy that ends before 20 weeks of gestation. Many factors can lead to it such as: age, smoking, etc. This study aimed to identify risk factors associated with spontaneous abortion. A descriptive study was the design. Purposive sample of 200 women diagnosed as spontaneous abortion were recruited. The setting was the emergency unit, at Woman's Health Hospital, Assiut university . The tool of data collection was an interview questionnaire which contains personal data, menstrual, obstetrical, medical and current history, other risk factors . The results of the study showed that 81% of study group were aged between 20-35years old, 54.5% were no and low level of education, 90% were from rural areas &91%were housewives. The late abortion represented 57.5%, while the missed abortion was the most frequent type of spontaneous abortions (38%). Nearly half of the study group (47.5%) exposed to passive smoking. The study concludes that the risk factors relating to the spontaneous abortion were rural residency, low level of education, short spacing, exposure to passive smoking & previous abortion. The study recommended to increase the women' awareness about the risk factors of spontaneous abortion . Encouraging early & regular antenatal care (ANC). Encouraging preconception counseling.
