Effects of perinatal loss on British Columbian obstetric nurses
Creators: name: Devic, Adisa
Publisher: name: University of British Columbia
Year: 2018

description: Background: Perinatal loss is a common occurrence on obstetric units. The effects of perinatal loss are far reaching and have profound effects on the families experiencing it, and on the nurses who care for them. Explorations of what exactly these effects are on the nursing staff providing bereavement care is lacking. Purpose: To explore the experiences of obstetric nurses who have provided care to families undergoing a perinatal loss. Methods: A qualitative descriptive design informed by principles of interpretive phenomenology was used to explore the effects of perinatal loss on nurses. A purposive sampling technique included eight nurses. Open-ended questions using a semi-structured approach guided the interviews. Results: The eight nurses interviewed were unanimous in their descriptions of how the lack of support and time to care for families experiencing perinatal loss significantly impacted their own experiences of providing care. Both positive and negative experiences were shared about the impacts of perinatal loss; yet when support and time were lacking, participants reported significant negative effects. Conversely, when nurses had adequate supports in place and the time to spend with their bereaved patient, as well as time for self-care, positive experiences were described. Finally, participants described perinatal bereavement work as highly valuable work, for which their involvement was considered a privilege. Implications: This study highlights the importance of education, preparation and support for nurses within the context of perinatal loss. The study findings point to the importance of resourcing support and prioritizing the time needed for nurses to minimize the negative effects of caring for families experiencing perinatal loss. It also highlights that strategies need to be in place for nurses to support each other to promote experiences that are more positive. Nurse leaders emerged in the study as a significant resource for shaping a climate of care and perinatal practice to mitigate the negative effects described in the literature and this study, while also advocating for the necessary resources, time and nurse-to-nurse support that can facilitate meaningful work for nurses as they care for families experiencing perinatal loss.

description: We study the survival probability and the corresponding first passage time density of fractional Brownian motion confined to a two-dimensional open wedge domain with absorbing boundaries. By analytical arguments and numerical simulation we show that in the long time limit the first passage time density scales as t**{-1+pi*(2H-2)/(2*Theta)} in terms of the Hurst exponent H and the wedge angle Theta. We discuss this scaling behaviour in connection with the reaction kinetics of FBM particles in a one-dimensional domain.

Origen
Christian reflexive theology

description: This article examines theoretical principles of Origen’s biblical hermeneutics and some fundamental features of his scientific method for the explanation of the scriptural text. In discussing the conceptual ground of biblical hermeneutics, the author focuses on the originality of the great Alexandrian’s cognitive model, contrary to that of Greek Philosophy, predominantly of Platonism, by which he was strongly influenced. The essential peculiarities of Origen’s scholarly thinking are presented as: a) a drastic agnostic point in regard to a mere intellectual quest of mind; b) the relationship of logical-discursive reasoning with biblical evidence as an alternative method of thinking to philosophy; c) biblical evidence as a true premise for attaining the truth through scholarly reasoning. Furthermore, Origen is considered to have played a highly important role in the development of allegorical interpretation of the Bible established in the Alexandrian theological tradition. Although Origen follows his predecessors in acknowledging the significance of historical and moral interpretations of the biblical narrative, his consistent adherence to the Transcendent results in the construction of allegorical metaphysics in a systematic manner. The paper also dwells on the idea of the veiled truth of the Scripture, the reception Paul’s ‘shadow’ theology, being based on Christological economy of revelation, and the novel system of the Christian metaphysics of language constructed by Origen. After outlining the common conceptual ground, the discourse briefly turns to some main themes which illustrate the techniques of the Alexandrian’s scholarly hermeneutics: ‘equivocality’ and ‘paradox’, multiplication of the object and its perigraphy, the biblical language and an articulation of a biblical interpreter. The author of this paper maintains that in his enterprise to corroborate the records of faith by constructing a scholarly doctrine, Origen not only founded biblical hermeneutics, but also constructed the first systematic exposition of the Christian faith – that is, Christian reflexive theology.
Regulation of lipin phosphorylation and lipid homeostasis by glycogen synthase kinase 3
Creators: name: Chan, Leslie Jing
Publisher: name: University of British Columbia
Year: 2020

description: It is imperative for cell survival and function to maintain proper steady-state lipid levels, or lipid homeostasis. This has significant physiological consequences, as lipid homeostasis is disrupted in metabolic diseases including obesity and diabetes, which necessitates a greater understanding of this cellular phenomenon. The lipin family of phosphatidic acid phosphatases are conserved enzymes that control the cellular balance of phospholipid and triglyceride synthesis, and mammalian lipins can also regulate lipid synthesis through interacting with transcription factors in the nucleus. Unsurprisingly, lipins are tightly regulated enzymes and a conserved mechanism of lipin regulation is phosphorylation by kinases, which can control the subcellular localization of lipins from the cytoplasm to other cellular compartments. To date, various kinases have been identified that phosphorylate lipins including the mechanistic target of rapamycin complex 1 (mTORC1), which controls lipin 1 localization from the cytoplasm to the nucleus and the ability of lipin 1 to repress sterol regulatory element binding protein (SREBP) target-gene transcription and thus cholesterol and fatty acid biosynthesis and uptake. A high-throughput screen seeking novel kinase regulators of lipins has never been performed. In this work, we designed an overexpression screen in yeast and identified Mck1, a glycogen synthase kinase 3 (GSK3) kinase, as a novel regulator of lipins and lipid homeostasis. We further discovered that this relationship was conserved from yeast to mammals by characterizing that mammalian GSK3 phosphorylates lipin 1 directly. GSK3 activity, downstream of the PI3K/Akt pathway, towards lipin 1 was found to control its localization, and in the absence of GSK3 activity, lipin 1 translocated to the nucleus and repressed SREBP target-gene expression. We observed that regulation of SREBP-target gene expression in this pathway was dependent on lipin 1 and additionally that both GSK3 paralogs, GSK3α and GSK3β, appeared to be involved. Finally, we characterized the role of GSK3 in lipid metabolism using mouse models and found that mice lacking GSK3α or GSK3β in the liver demonstrated resistance to some effects of diet-induced obesity including weight gain and the expression of certain SREBP target genes, suggesting that GSK3 in the liver plays a role in the development of these phenotypes.

description: High-precision pulsar timing relies on a solar-system ephemeris in order to convert times of arrival (TOAs) of pulses measured at an observatory to the solar system barycenter. Any error in the conversion to the barycentric TOAs leads to a systematic variation in the observed timing residuals; specifically, an incorrect planetary mass leads to a predominantly sinusoidal variation having a period and phase associated with the planet's orbital motion about the Sun. By using an array of pulsars (PSRs J0437-4715, J1744-1134, J1857+0943, J1909-3744), the masses of the planetary systems from Mercury to Saturn have been determined. These masses are consistent with the best-known masses determined by spacecraft observations, with the mass of the Jovian system, 9.547921(2)E-4 Msun, being significantly more accurate than the mass determined from the Pioneer and Voyager spacecraft, and consistent with but less accurate than the value from the Galileo spacecraft. While spacecraft are likely to produce the most accurate measurements for individual solar system bodies, the pulsar technique is sensitive to planetary system masses and has the potential to provide the most accurate values of these masses for some planets.

description: Supplementary information of submitted publication "AG-205 upregulates enzymes involved in cholesterol biosynthesis and steroidogenesis in human endometrial cells independently of PGRMC1 and related MAPR proteins"Abstract:Inappropriate response to progestogens in the human endometrium can result in fertility issues and jeopardize progestin-based treatments against pathologies such as endometriosis. PGRMC1 can mediate progesterone response in breast and ovary but its endometrial functions remain unknown. AG-205 is an alleged PGRMC1 inhibitor but its specificity was recently questioned. We added AG-205 in cultures of two endometrial cell lines and performed transcriptomic comparison. AG-205 significantly increased expression of genes coding enzymes of the cholesterol biosynthetic pathway or of steroidogenesis. However, these observations were not reproduced with cells transfected with siRNA against PGRMC1 or its related proteins (MAPRs). Furthermore, AG-205 retained its ability to increase expression of selected target genes even when expression of PGRMC1 or all MAPRs was concomitantly downregulated, indicating that neither PGRMC1 nor any MAPR is required to mediate AG-205 effect. In conclusion, although AG-205 has attractive effects encouraging its use to develop therapeutic strategies, for instance against breast cancer, our study delivers two important warning messages. First, AG-205 is not specific for PGRMC1 or other MAPRs and its mechanisms of action remain unclear. Second, due to its effects on genes involved in steroidogenesis, its use may increase the risk for endometrial pathologies resulting from imbalanced hormones concentrations.

description: We investigate experimentally and theoretically the behavior of the confined dark exciton in an InAs/GaAs semiconductor quantum dot, under the application of an external magnetic field in Voigt configuration. We show that by varying the magnitude and direction of the external field one can accurately control the dark-exciton fine-structure splitting. In addition, we show that the dark-exciton spin state is approximately polarized along the cubic crystallographic directions [100] or equivalents. By comparing our experimental results with a model for the exchange and Zeeman interactions, we find the conditions for nullifying the fine-structure splitting between the two eigenstates of the dark exciton, thereby stopping its qubit precession.

description: The non-equilibrium self-consistent generalized Langevin equation theory of colloid dynamics is used to describe the non-stationary aging processes occurring in a suddenly quenched model colloidal liquid with hard-sphere plus short-ranged attractive interactions, whose static structure factor and van Hove function evolve irreversibly from the initial conditions before the quench to a final, dynamically arrested state. The comparison of our numerical results with available simulation data are highly encouraging.

description: Motivated by the `subgraphs world' view of the ferromagnetic Ising model, we develop a general approach to studying mixing times of Glauber dynamics based on subset expansion expressions for a class of graph polynomials. With a canonical paths argument, we demonstrate that the chains defined within this framework mix rapidly upon graphs of bounded tree-width. This extends known results on rapid mixing for the Tutte polynomial, the adjacency-rank ($R_2$-)polynomial and the interlace polynomial.

description: Supermassive black holes presumably grow through numerous mergers throughout cosmic time. During each merger, supermassive black hole binaries are surrounded by a circumbinary accretion disk that imposes a significant (~1e4 G for a binary of 1e8 Msun) magnetic field. The motion of the binary through that field will convert the field energy to Poynting flux, with a luminosity ~1e43 erg/s (B/1e4 G)^2 (M/1e8 Msun)^2, some of which may emerge as synchrotron emission at frequencies near 1 GHz where current and planned wide-field radio surveys will operate. We find that the short timescales of many mergers will limit their detectability with most planned blind surveys to <1 per year over the whole sky, independent of the details of the emission process and flux distribution. Including an optimistic estimate for the radio flux makes detection even less likely, with <1 mergers per year over the whole sky. However, wide-field radio instruments may be able to localize systems identified in advance of merger by gravitational waves. Further, radio surveys may be able to detect the weaker emission produced by the binary's motion as it is modulated by spin-orbit precession and inspiral well in advance of merger.

description: Application of artificial intelligence (AI) in precision oncology typically involves predict-ing whether the cancer cells of a patient (previously unseen by AI models) will respondto any of a set of existing anticancer drugs, based on responses of previous training cellsamples to those drugs. To expand the repertoire of anticancer drugs, AI has also beenused to repurpose drugs that have not been tested in an anticancer setting, i.e., predict-ing the anticancer effects of a new drug on previously unseen cancer cellsde novo. Here,we report a computational model that addresses both of the above tasks in a unified AIframework. Our model, referred to as deep learning-based graph regularized matrix factor-ization (DeepGRMF), integrates neural networks, graph models, and matrix-factorizationtechniques to utilize diverse information from drug chemical structures, their impact oncellular signaling systems, and cancer cell cellular states to predict cell response to drugs.DeepGRMF learns embeddings of drugs so that drugs sharing similar structures and mech-anisms of action (MOAs) are closely related in the embedding space. Similarly, DeepGRMFalso learns representation embeddings of cells such that cells sharing similar cellular statesand drug responses are closely related. Evaluation of DeepGRMF and competing modelson Genomics of Drug Sensitivity in Cancer (GDSC) and Cancer Cell Line Encyclopedia(CCLE) datasets show its superiority in prediction performance. Finally, we show that themodel is capable of predicting effectiveness of a chemotherapy regimen on patient outcomesfor the lung cancer patients in The Cancer Genome Atlas (TCGA) dataset.

description: Υπό συνθήκες καταπόνησης οι κοινότητες των θυσανωδών μυκορριζικών μυκήτων (ΘΜΜ) είναι πιθανό να επηρεαστούν. Ωστόσο, δεν έχει μελετηθεί αρκετά το κατά πόσο μπορεί να επηρεαστεί η εγκατάσταση μυκορριζικών εμβολίων, καθώς επίσης και το αν είναι εφικτή η εγκατάσταση ενός εμβολίου ΘΜΜ σε καλλιέργειες πολυετών φυτών, οι οποίες είναι ήδη αποικισμένες από γηγενείς κοινότητες ΘΜΜ. Σε ήδη εγκατεστημένο και αποικισμένο αμπελώνα εφαρμόστηκε με εμβολιασμό ο μύκητας Septoglomus deserticola και με τεμαχίδια-προϊόντα αντίδρασης ενζύμων περιορισμού σε προϊόντα PCR διερευνήθηκε η εγκατάσταση του μύκητα δύο χρόνια μετά την εφαρμογή του και αν και πώς αυτή επηρεάζεται από υδατική καταπόνηση. Μετρήθηκε επίσης το ποσοστό αποικισμού του μήκους των ριζών από ΘΜΜ για ένα και δύο χρόνια μετά τον εμβολιασμό. Τα αποτελέσματα έδειξαν πως η εφαρμογή υδατικής καταπόνησης δεν είχε κάποια επίδραση, ενώ το αποτύπωμα της κοινότητας των ΘΜΜ μετά τον εμβολιασμό διαφοροποιήθηκε. Ο αποικισμός, πιο συγκεκριμένα, επηρεάστηκε από τον εμβολιασμό μόνο σε αλληλεπίδραση με τη χρονιά, χωρίς να υπάρχει σταθερή αύξηση ή μείωση κάθε χρονιά. Η εφαρμογή εμβολιασμού με ΘΜΜ σε εγκατεστημένες πολυετείς καλλιέργειες έχει νόημα στοχεύοντας στην δυνατότητα του μυκορριζικού εμβολίου να ανταγωνιστεί, να επιβιώσει, ίσως ακόμη και να κυριαρχήσει, έναντι της τοπικής κοινότητας των ΘΜΜ. Η εφαρμογή υδατικής καταπόνησης δεν φαίνεται να ευνόησε ή να εμπόδισε την εγκατάσταση ενός μύκητα με προέλευση από περιβάλλον ερήμου.
description: Under stress conditions arbuscular mycorrhizal fungal (AMF) communities can probably be affected. However, it has not been studied enough how they may affect the establishment of an AMF inoculum, as also if such an inoculum may be established in an already colonized by native AMF communities perennial crop. Inoculum of Septoglomus deserticola was applied in an already established and colonized vineyard and, using restriction fragment length polymorphism, the establishment of the fungus and how this was affected by deficit irrigation was investigated, two years after inoculation. In addition, root length colonization by AMF was measured one and two years after inoculation. The results showed that the application of drought stress had no effect, however, the histogram resulting from the RFLP pattern of the AMF community clustered with inoculation. In particular, the colonization was affected by inoculation, only in interaction with year, without a clear, consistent increase or decrease with inoculation. Applying mycorrhizal inoculation in perennial crops is meaningful, in the sense of the ability of the inoculum to compete with local fungi, survive and establish itself in the rhizosphere. Application of water deficit stress had no indication of affecting positively or negatively the establishment of an AMF originating for a desert environment.

description: Research has shown that in small businesses in Georgia, social capital, as the link between social network and business, is unused. Social networking does not significantly affect employment or entrepreneurship quality. Social integration with the support from the government is a tool to overcome business problems. Relationships with CSOs are the most consistent sources of social capital. Owning information and connecting with local government is not enough for entrepreneurs in Georgia to boost their business. As the study shows, the important factors for starting a business are expanding the diversity of business relationships and networks, training in business issues conducted by various organizations, developing information channels, consulting institutes, and networking. Needs, which are common in business, include increasing access to loans and technology, institutional support to trade with products / services by using activities such as targeted employment trai-nings (for example, hospitality and hotel management services) in order to improve and expand entrepreneurship skills and business relations and partnership in terms of supply chain strategy. It is noted that in Georgia important business-supporting state programs are being implemented. However, it should also be emphasized that direct impacts on the development of small entrepreneurship are neither institutionally nor financially effective. Recommendations are presented for providing educational and consulting services, access to finance, information on networks and business programs.

description: Little is known about the trajectory of tinnitus over time. This study addressed (1) how often tinnitus remitted in patients with chronic tinnitus; (2) how subjective reported tinnitus characteristics, such as loudness, laterality, and type and measures of burden, such as tinnitus distress, depression, and quality of life, changes over time; (3) how often tinnitus-specific treatments were undertaken and the prevalence of comorbidities, (4) if the number of treatments and comorbidities were associated to changes in tinnitus distress over time. Data from 388 patients with chronic tinnitus who visited a tertiary tinnitus clinic between 2012 and 2017 were interrogated via a mail survey in 2018. Tinnitus characteristics were measured with the Tinnitus Sample Case History Questionnaire and numeric rating scales; tinnitus distress with Tinnitus Handicap Inventory (THI) and the Tinnitus Questionnaire (TQ), depression with the Major Depression Inventory and Quality of life with the World Health Organisation Quality of Life BREF at both time points and the clinical global impression scale. Comorbidities experienced and undertaken treatments were assessed with an in-house survey. Three participants (0.8% of the sample) reported tinnitus remission between both assessments. A decrease in the THI and TQ, and numeric ratings for tinnitus severity, annoyance, unpleasantness, and discomfort was observed, but no differences in tinnitus characteristics, depression, quality of life or overall health status. 64% presented at least one comorbidity, and 88% sought at least on tinnitus-specific treatment. Common comorbidities were psychological and sleeping problems, and the most common interventions were going to the dentist, taking medications, and wearing hearing aids. Our results suggest that full remission of tinnitus is a rare condition, that tinnitus distress on average decreases over time, and that tinnitus characteristics, quality of life, and depression tend to remain unaltered. The high number of interventions and comorbidities displayed minimal association to the changes in tinnitus distress, highlighting the substantial and durable burden of tinnitus sufferers.

description: The aim of this paper is to increase role of innovation and specification of its functions under the modern challenges, as the key factor for the sustainable political-economic and social development of countries, as well as the rational use of resources and sustainable environmental protection; As well as introducing new approaches as an opportunity to accelerate expanding the role of innovation. In the definition of economic space of innovation, the objectives of sustainable development are also considered, as the implementation of the requirements of sustainable development objectives necessarily has both a spatial dimension of action and the dimension of environmental impact as a result of human activity. This implies both qualitative and quantitative spatial dimensions and an integral combination. In such approaches, direct economic interests change and it becomes clear who can create the hidden forces of contrary action that oppose targeted positive action. At the same time, the set and agreed global standards of economic area will become an authentic tool to overcome such overt or covert opposite forces that have only a consumer attitude towards the economic space. In the paper, the increase of innovation utilization index is presented as a proportion to the growth of socio-economic and political development and inverse dimension to poverty and environmental imbalances. In addition, the leading role of innovation, socio-economic environment and sustainable economic development are discussed in the three-dimensional model of the systems’ life cycle.

description: Highly polarized nuclear spins within a semiconductor quantum dot (QD) induce effective magnetic (Overhauser) fields of up to several Tesla acting on the electron spin or up to a few hundred mT for the hole spin. Recently this has been recognized as a resource for intrinsic control of QD-based spin quantum bits. However, only static long-lived Overhauser fields could be used. Here we demonstrate fast redirection on the microsecond time-scale of Overhauser fields of the order of 0.5 T experienced by a single electron spin in an optically pumped GaAs quantum dot. This has been achieved using full coherent control of an ensemble of 10^3-10^4 optically polarized nuclear spins by sequences of short radio-frequency (rf) pulses. These results open the way to a new class of experiments using rf techniques to achieve highly-correlated nuclear spins in quantum dots, such as adiabatic demagnetization in the rotating frame leading to sub-micro K nuclear spin temperatures, rapid adiabatic passage, and spin squeezing.

description: It is shown that the "new" neutrino with a high mass squared difference and a small mixing angle should reveal itself in the oscillometry measurements. For a judicious monochromatic neutrino source the "new" oscillation length $L_{42}$ is expected shorter than 1.5 m. Thus the needed measurements can be implemented with a gaseous spherical TPC of modest dimensions with a very good energy and position resolution. The best candidates for oscillometry are discussed and the sensitivity to the mixing angle $θ_{14}$ has been estimated: $\sin^2{(2θ_{14})}$=0.05 (99{%}) for two months of data handling with $^{51}$Cr.

description: This study examines the influence (effects) of export diversification in economic growth across post-soviet countries. In a sample of seven countries for the period 1997-2019 the dynamic panel estimation reveals that export diversification is important determinant of economic growth, Estimating the impacts of other variables are also important. These variables are: lagged growth, trade openness, investment, Education, Agriculture/GDP ratio, Manufacturing/GDP ratio, Services/GDP ratio, Population growth. It is found that countries with more diversified exports generally experienced faster economic growth. Results of the study indicates that export diversification has an influence on economic growth. A positive relation between export diversification and growth is established and it suggests that countries with a higher rate of export diversification (less concentration) experience a higher rate of economic growth. Moreover, the results show both export diversification and export growth are robust determinants of growth rates while trade openness is not robust. This suggests that for countries striving to achieve economic growth, export diversification should go along with the growth of its exports

description: The requirements of the design and construction market in the context of a global pandemic era are fundamentally different from the usual picture of previous years. The economic crisis affected all sectors of the national economy In general, but one of the most important areas – tourism, should be especially noted, the income of which is an important and reliable source of budget replenishment, and the development of which was largely determined by the size and intensity of foreign tourist flows. Extraordinary measures were taken by the state to protect the population: The closure of the country's external gates, the quarantine regime, social distancing, etc. caused complete stagnation in this area; The suspension of the tourism activities has created many problems for employers and industry workers, operating companies and the budget. No effective ways to get out of the current crisis situation have yet been found, but there are alternative directions, the emergence of which is associated with pre-design multidisciplinary research and the preparation of the necessary feasibility studies based on the generalization of their results. One of these promising areas is a new understanding of the river factor in the historical development; In this respect, the Mtkvari River represents a significant spatial planning environment for the development of Tbilisi's tourism infrastructure. The article discusses the possibilities of using the banks of the river and its underwater space to create attractive tourist objects. The challenges of the circular economy determine the architectural and planning conditions and the composition of design and technical specifications for the construction of specific buildings and structures

description: Introduction Football is the most popular sport worldwide and results in a high frequency of injuries. So far, mainly injuries in professional football have been investigated, and the literature lacks data regarding detailed injury epidemiology and current prevention data in amateur football tournaments. Materials and methods A prospective cohort study investigated an international amateur football tournament, the UEFA Regions’ Cup, which took place in 2019 in Germany. Injury epidemiology, current prevention strategies of the teams and the implementation of the UEFA concussion protocol were investigated in detail by means of standardized injury definitions and data samples for football (Fuller et al., Scand J Med Sci Sports 16:83–92, https:// doi. org/ 10. 1111/j. 1600- 0838. 2006.00528.x, 2006). Results 138 player of 8 teams participated in this study, while 39 players were excluded. Overall injury incidence was 12.5 per 1000 h total football exposure, 43.5 per 1000 h for match exposure. No injuries were registered during training. Injury prevalence was 14.1% per player and 1.1 injuries per match were registered. The lower extremity was predominantly affected by injuries (71.4%) and the majority of injuries (78.6%) were non-severe injury types like contusions (50%) and sprains (18.2%). Two head injuries, one contusion and one skin lesion, were handled by the guidelines of the UEFA concussion protocol. 44.4% of the players indicated at least one previous injury before tournament, 45.3% of them during the last two football seasons before start of the tournament. Injury prevention performance was included in all participating teams during the tournament by warm up or training strategies (100%). During the warm-up program just 5 exercises of the FIFA 11 + program was detected by this investigation in participating teams to be done by more half of the teams. Running exercises were the most frequently performed exercises, while trunk muscle exercises were less represented (14.3%). Conclusion This study presents for the first time epidemiological injury and prevention data of the UEFA Regions Cup. Injury incidence was higher compared to injury reports of regular seasons, but lower compared to other amateur football tournaments. Currently used prevention programs revealed trunk muscle exercises as often neglected.

description: Since 2008, when the cryptocurrency was first introduced under the name Satoshi Nakamoto, more and more people are interested in the «new money» – Bitcoin. Bitcoin is the first cryptocurrency and although many other cryptocurrencies were created and will be created in the future, Bitcoin remains the most popular cryptocurrency to this day. Naturally, along with the rapid growth of information technologies and their applications, many new «computerized» currencies will emerge. Because anyone can buy and sell cryptocurrency (e.g. bitcoin) and, thus, cryptocurrency is a subject of trade, hence cryptocurrency and in particular bitcoin is a product. Naturally, questions arise about the determinants of cryptocurrency price changes. In particular: Are the changes in the prices of cryptocurrency (and in particular Bitcoin) related to the development trends of the global economy? Are changes in the prices of cryptocurrency (and in particular Bitcoin) related to indicators of the state of the global economy, such as the well-known indices DJII, Nasdaq, S&P 500 and others. Thus it is interesting to see whether it is possible to predict changes in the prices of cryptocurrencies (and in particular Bitcoin) using different methods of time series.

description: We report on the first detection of ionospheric disturbances caused by short repeated gamma-ray bursts from the magnetar SGR J1550-5418. Very low frequency (VLF) radio wave data obtained in South America clearly show sudden amplitude and phase changes at the corresponding times of eight SGR bursts. Maximum amplitude and phase changes of the VLF signals appear to be correlated with the gamma-ray fluence. On the other hand, VLF recovery timescales do not show any significant correlation with the fluence, possibly suggesting that the bursts' spectra are not similar to each other. In summary, the Earth's ionosphere can be used as a very large gamma-ray detector and the VLF observations provide us with a new method to monitor high energy astrophysical phenomena without interruption such as Earth Occultation.
