description: The last several years have seen major enhancements to ACL2 functionality, largely driven by requests from its user community, including utilities now in common use such as 'make-event', 'mbe', and trust tags. In this paper we provide user-level summaries of some ACL2 enhancements introduced after the release of Version 3.5 (in May, 2009, at about the time of the 2009 ACL2 workshop) up through the release of Version 4.3 in July, 2011, roughly a couple of years later. Many of these features are not particularly well known yet, but most ACL2 users could take advantage of at least some of them. Some of the changes could affect existing proof efforts, such as a change that treats pairs of functions such as 'member' and 'member-equal' as the same function.

alternative data sources

description: Author presents a large-scale comparison of five multidisciplinary bibliographic data sources: Scopus, Web of Science, Dimensions, Crossref, and Microsoft Academic. Coverage differences between those data sources are determined at the level of individual scientific documents. The analysis relates to all documents processed by these data sources from the period 2008-2017. We will focus on differences in coverage of disciplines, of different types of publication sources (journals, proceedings etc.) and of publication years. Apart from coverage we will also discuss data quality and data enrichment aspects of the different data sources. More specifically we will present results of an analysis regarding the completeness and accuracy of citation links and the completeness of author affiliations and the degree to which these affiliations are linked to internal or external registers of standardized organizations. The investigation into the strengths and limitations of alternative data sources on publication output that are available under different conditions and costs is highly relevant for the future of the RISIS data infrastructure.

Delayed solidification of soft glasses: New experiments, and a theoretical challenge

description: When subjected to large amplitude oscillatory shear stress, aqueous Laponite suspensions show an abrupt solidification transition after a long delay time tc. We measure the dependence of tc on stress amplitude, frequency, and on the age-dependent initial loss modulus. At first sight our observations appear quantitatively consistent with a simple soft-glassy rheology (SGR)-type model, in which barrier crossings by mesoscopic elements are purely strain-induced. For a given strain amplitude γ0 each element can be classified as fluid or solid according to whether its local yield strain exceeds γ0. Each cycle, the barrier heights E of yielded elements are reassigned according to a fixed prior distribution ρ(E): this fixes the per-cycle probability R(γ0) of a fluid elements becoming solid. As the fraction of solid elements builds up, γ0 falls (at constant stress amplitude), so R(γ0) increases. This positive feedback accounts for the sudden solidification after a long delay. The model thus appears to directly link macroscopic rheology with mesoscopic barrier height statistics: within its precepts, our data point towards a power law for ρ(E) rather than the exponential form usually assumed in SGR. However, despite this apparent success, closer investigation shows that the assumptions of the model cannot be reconciled with the extremely large strain amplitudes arising in our experiments. The quantitative explanation of delayed solidification in Laponite therefore remains an open theoretical challenge.

description: Landscape genetics is a new field that investigates the consequences of landscape features on population genetic patterns. The small lakes of Alberta, and the brook stickleback (Culaea inconstans) that inhabit them, provide a unique system where populations are highly fragmented and isolated from one another. These lakes are prone to winterkills hypothesized to precipitate frequent bottleneck events in brook stickleback populations. As predicted, brook stickleback populations exhibited a high degree of population structure, and were hierarchically structured by small scale watersheds. AIC analyses of the role of spatial features found support for basin characteristics in driving patterns of genetic diversity, which was also consistent with the detection of recent bottlenecks in at least five of the sampled lakes. These results suggest that brook stickleback population genetic patterns are primarily controlled by processes that accelerate genetic drift, reinforcing the importance of connectivity in the maintenance of genetic diversity in fragmented landscapes.
Preliminary results on forcing vine regrowth to delay ripening to a cooler period

description: The most important climate-change-related effect on wine grapes is the advance in the harvest period. The increase of temperature during the whole growing season, and consequently, the warmer conditions over ripening, lead to the production of unbalanced wines with high alcohol levels, low acidities, a modified varietal aroma and a lack of color. One of the strategies to mitigate these unpleasant effects consists on delaying the berry ripening to cooler conditions. With the aim of delaying the grape ripeness more than two months, the study of a technique consisting on forcing vine regrowth has been studied. This technique consists on cutting the green shoots off, between the second and the third node of each shoot and at different phenological stages (from state G to state K, according to the Baillod and Baggiolini system, 1993); leaves and lateral shoots of the first and second nodes are removed as well. Depending on the phenological stage of vines during the forcing treatment, the fruit ripening was shifted from one month to more than two months, i.e. this practice was effective to shift harvest time from the warm August to the cooler October and November. Forced vines produced smaller berries with lower pH and higher acidity and anthocyanins concentration, compared to non-forced vines. This treatment is an effective technique to restore the anthocyanin-to-sugar ratio decoupled by climate warming.

Dermal features derived from optoacoustic tomograms via machine learning correlate microangiopathy phenotypes with diabetes stage

Publisher: name: Zenodo

description: Skin microangiopathy has been associated with diabetes. Here we show that skin-microangiopathy phenotypes in humans can be correlated with diabetes stage via morphophysiological cutaneous features extracted from raster-scan optoacoustic mesoscopy (RSOM) images of skin on the leg. We obtained 199 RSOM images from 115 participants (40 healthy and 75 with diabetes), and used machine learning to segment skin layers and microvasculature to identify clinically explainable features pertaining to different depths and scales of detail that provided the highest predictive power. Features in the dermal layer at the scale of detail of 0.1–1 mm (such as the number of junction-to-junction branches) were highly sensitive to diabetes stage. A 'microangiopathy score' compiling the 32 most-relevant features predicted the presence of diabetes with an area under the receiver operating characteristic curve of 0.84. The analysis of morphophysiological cutaneous features via RSOM may allow for the discovery of diabetes biomarkers in the skin and for the monitoring of diabetes status.

description: We consider the problem of discriminating between two quantum coherent states by interpreting a single state like being a collection of several successive copies of weaker coherent states. By means of recent results on multiple-copy state discrimination, it is possible to give a reinterpretation of the Dolinar receiver, and carry out a quite straightforward analysis of its behavior. We also propose and investigate a suboptimal detection scheme derived from the Dolinar's architecture, which is shown to slightly outperform some other near-optimal schemes available in literature.

Improving fruit anthocyanins in 'Cabernet Sauvignon' by shifting fruit ripening and irrigation reduction post veraison in warmer region

Year: 2019

description: In warmer regions, forcing vines to regrow and shifting fruit ripening to the cooler portion of the growing season can increase the concentration of total fruit anthocyanins (TFA) in red winegrapes, but the effect on anthocyanin composition remains unclear. Additionally, irrigation reduction post veraison was reported to improve fruit anthocyanins in cool and temperate regions with low precipitation, whereas this response has not been previously examined in forced vines grown in dry and warm regions. Experiments were conducted with 'Cabernet Sauvignon' (Vitis vinifera L.) over two consecutive years in Fresno, California, to investigate the effect of shifting fruit ripening on the concentration and composition of fruit anthocyanins as well as the influence of post-veraison irrigation reduction on fruit anthocyanins of forced vines. Vines under conventional practices (non-forced) were used as the control. Forcing treatment included removing primary leaves, clusters, and laterals, as well as hedging primary shoots, in mid-June. Control vines were irrigated at 80 % crop evapotranspiration (ETC) post veraison, whereas forced vines were irrigated at 40, 60, 80, or 100 % ETC post veraison. Results suggest that forcing vines to regrow and shifting fruit ripening led to a significant increase of TFA, primarily non-acylated anthocyanins, during fruit ripening and at harvest over two years. Forcing treatment also altered composition of fruit anthocyanins at harvest, with increased proportions of TFA comprised by the glucosides of delphinidin and petunidin but the decreased proportion of the glucosides of malvidin. This study demonstrates that forcing vines to regrow and shifting fruit ripening in the warmer region can lead to a more balanced profile of fruit anthocyanins, with improved non-acylated derivatives and altered relative abundance of the glucosides of five anthocyanidins. Reducing irrigation post veraison, however, had only a minor effect on fruit anthocyanins in forced vines.

Consolidating approaches: how the Public Policy Taxonomy was made

Subjects: vocabularies

description: In 2017, the Analysis and Policy Observatory (APO) set out to improve the way subject vocabularies were used in the APO website. Another goal was to make APO subject vocabularies share-able with collaborators, as part of the Linked Semantic Platforms project (LE180100094). Over three years of development, rationalization and consolidation, APO achieved these objectives, resulting in the Public Policy Taxonomy (PPT). This case study discusses the strategies, systems and tools employed to revise, consolidate, and publish the PPT. Challenges that confronted the APO team and project are also discussed.

 This case study presents a strategy involving bottom-up vocabulary development and alignment with external vocabularies and authorities. The PPT is the result of a combination of approaches and inputs, where disparate sources and workflows were consolidated. Key drivers of this work were: improve APO website useability; simplify business investment in vocabulary management and workflows; and enable sharing PPT via services.

 The case study will reveal the disparate inputs to the PPT and how these were wrangled. A key starting point were ‘home grown’ keyword lists that were refined using taxonomy automation methods (Kang et al, 2021). PPT also absorbed textual and structural elements from the Fields of Research (FOR), Australian Public Affairs Information Service Thesaurus (APAIS), Australian Government’s Interactive Functions Thesaurus (AGIFT), Faceted Application of Subject Terminology (FAST), and in some cases made concept-level, machine-readable mappings to elements within these vocabularies. Engagement with these established vocabularies will be discussed in the case study.

 PPT is available as a SKOS vocabulary within the Research Vocabularies Australia service. PPT continues to be updated but is arguably an unfinished case study: for example, there remain challenges for community engagement and persistent identifier issues. The case study will present concluding remarks about lessons learned from the project.

description: We measure the spatial extent of individual localized photonic states in a slow-light photonic crystal waveguide. The size of the states is measured by perturbing each state individually through a local electromagnetic interaction with a near-field probe. We find localized states which are not observed in transmission and show that these states are shorter than the waveguide. We also directly obtain near-field measurements of the participation ratio, from which the size of the states can be derived, in quantitative agreement with the size measured with the perturbation method.

description: 'Garnacha Blanca' is a somatic variant derived from 'Garnacha Tinta', an old variety with large genetic and phenotypic variability. In this work we have studied for two years the phenotypic variation existing in 'Garnacha Blanca' for yield and quality related traits in accessions from 14 sampling locations of ancient vineyards in the Ebro Valley, Spain. The results showed high variability among the accessions in many of the traits studied in 'Garnacha Blanca'. Different accessions could be distinguished both years using several traits, including two important traits in terms of quality and yield: bunch compactness and yield per plant. A large environment effect, intrinsic to the 'Garnacha' group, enhances phenotypic variation among years, what requires increasing the number of bunches and years for clonal characterization in this variety. The dimensions of the berry showed the least variability, while traits related to bunch architecture like bunch length were discriminant and also stable.

I-ADOPT: a semantic broker for variable descriptions across terminologies

Subjects: vocabularies

description: The I-ADOPT Interoperability Framework is a set of guidelines endorsed as RDA recommendations that help to provide interoperability between terminologies used to represent observable properties/variables. It is based on a simple non-domain specific ontology that supports the decomposition of complex observable properties into their essential atomic parts represented through the concepts in FAIR terminologies. While it enables semantically precise and FAIR descriptions of variables it also provides abstract reusable semantic descriptions for concrete observations. Acting as semantic broker the I-ADOPT Framework facilitates the mapping between variable descriptions across terminologies without changing the original structure, but requires adding a rich (human and machine readable) description with qualified references which will boost the findability and the reusability of observational data.

 The RDA Working Group is now in maintenance mode focusing on the implementation of the recommendations in different use cases such as the description of eLTER Standard Observations in EnvThes, the alignment of two major earth sciences parameter labeling schemes in NERC Vocabulary Server - the Climate and Forecast (CF) Standard Names and the British Oceanographic Data Centre Parameter Usage Vocabulary (BODC PUV) and the extension of the SensorThings API with I-ADOPT components. The presentation will concentrate on lessons learned from these use cases including the limitations and possible improvements and extensions of the framework.

This event series, currently comprised of four online events is a collaboration between AI3 Science Discovery Network+, Patterns & the Physical Sciences Data-Science Service (PSDS). This event series follows on from a data sharing survey that was undertaken earlier in 2020. Each event in the series handles a different aspect of dealing with data aiming to educate and inform researchers about how to work well with their data, as well as encouraging discussion along the way. Following on from these events the organisers hope to be able to organise more face-to-face events in 2021 which will expand this event series. Understanding the different data standards that are available is absolutely essential to any data-driven research, irrespective of the type of data. In these events we want to encourage re- searchers to consider this as a fundamental aspect of managing, presenting and organising their data rather than an afterthought, or something they wish they did but never got round to. This event aimed to provide an introduction to the different types of data standards, alongside examples of their usage and suggestions for best practices.

description: The foundational theory of differentiation was developed as part of the original release of ACL2(r). In work reported at the last ACL2 Workshop, we presented theorems justifying the usual differentiation rules, including the chain rule and the derivative of inverse functions. However, the process of applying these theorems to formalize the derivative of a particular function is completely manual. More recently, we developed a macro and supporting functions that can automate this process. This macro uses the ACL2 table facility to keep track of functions and their derivatives, and it also interacts with the macro that introduces inverse functions in ACL2(r), so that their derivatives can also be automated. In this paper, we present the implementation of this macro and related functions.

description: The main objective of this thesis is the development and feasibility testing of a proposed multispectral contactless hand biometric authentication system based on the Kinect v2 sensor. To achieve the goal of contactless authentication the hand images of the user are extracted in the red-green-blue, near-infrared, and depth spectra in real time. These extracted frames are then passed through an eigenhands based recognition system. To ensure the results carry across different classification methods both K-Nearest-Neighbours and Support Vector Machines are tested. The proposed hand recognition system is tested using a locally collected database of many different users recorded in the three spectra available using the Kinect v2 sensor. Through experimentation with the collected database and validation of the parameters used in the classification methods the feasibility of the proposed hand recognition system is proven.

description: The grapevine intra-specific variability captured an increasing interest during the last decades, as demonstrated by the number of recently funded European projects focused on the grapevine biodiversity preservation. However, nowadays, crop plants are mainly characterized by genotyping methods. The present work summarizes the phenotype data collected among 20 ampelographic collections spread in 15 countries, covering mostly of the viticultural areas in the Euro-Asiatic range: from Portugal to Armenia and from Cyprus to Luxembourg. Together with agro-climatic characterization of the experimental site, in two years, about 2400 accessions were described, following a common experimental protocol mainly focused on the carpological and oenological traits, obtaining a general overview of the distribution of the considered phenotypic traits in the cultivated Vitis vinifera species. The most replicated cultivars were selected and, for the subset of these reference cultivars, their behavior in the different environmental conditions over sites and years was described by ANOVA methods.

description: Three transgressive-regressive systems tracts are interpreted in the Bakken Formation in southeastern Alberta and southwestern Saskatchewan based on analysis of cores and well logs. These systems tracts include a basal transgressive systems tract TST1, a regressive systems tract RST and a transgressive systems tract TST2. Three distinct systems tracts are interpreted within Bakken RST; these are high stand systems tract (HST), Falling stage systems tract (FSST) interpreted within the Bakken Formation and a lowstand systems tract within the Exshaw Formation to the west. Fluctuations in base level that resulted from changes in relative sea level and tectonics controlled the deposition of the Bakken Formation. Detrital zircon geochronology and reworked conodonts from the Bakken middle member indicate sediment transport from multiple sources. Thrust-belt sources associated with the Franklinian Orogeny to the north and northeast contributed the majority (no less than 25%) of the Bakken clastic budget. The two mechanisms for Bakken sediments delivery are continental scale fluvial systems and longshore drift of sediments.

description: The analysis of x-ray reflectivity data from artificial heterostructures usually relies on the homogeneity of optical properties of the constituent materials. However, when the x-ray energy is tuned to the absorption edge of a particular resonant site, this assumption may no longer be appropriate. For samples realizing lattice planes with and without resonant sites, the corresponding regions containing the sites at resonance will have optical properties very different from regions without those sites. In this situation, models assuming homogeneous optical properties throughout the material can fail to describe the reflectivity adequately. As we show here, resonant soft x-ray reflectivity is sensitive to these variations, even though the wavelength is typically large as compared to the atomic distances over which the optical properties vary. We have therefore developed a scheme for analyzing resonant soft x-ray reflectivity data, which takes the atomic structure of a material into account by ‘slicing’ it into atomic planes with characteristic optical properties. Using LaSrMnO₄ as an example, we discuss both the theoretical and experimental implications of this approach. Our analysis not only allows to determine important structural information such as interface terminations and stacking of atomic layers, but also enables to extract depth-resolved spectroscopic information with atomic resolution, thus enhancing the capability of the technique to study emergent phenomena at surfaces and interfaces.

description: Wine grape is usually grown under water deficit conditions that could negatively impact plant reserves, including the organic carbon storage in perennial organs such as woody stems. Assessing the carbohydrate status in woody organs is therefore of interest as it can influence vegetative growth in the successive season. In this study, we aimed to apply an on-solid colour reaction (using Lugol's iodine solution) coupled with reflectance spectroscopy detection to assess the grapevine canes' starch accumulation in response to short drought periods. We used two Vitis vinifera cultivars ('Cabernet Sauvignon' and 'Syrah') that were subjected to three different water conditions (well-watered; early water stress; late water stress) during the growing season as case study. We sampled woody stem tissue during winter rest. The results showed that water stress reduced the starch storage in 'Syrah', especially when imposed late and recovery time was not enough for carbon restoration, while 'Cabernet Sauvignon' was not affected. The results showed that the sensitivity of the method used here is adequate to assess starch accumulation differences due to drought treatments in grapevine canes. Moreover, the analytical approach appears fast, low cost, and promising for future physiological and agronomical research applications.

description: This paper examines a continuous-time routing system with general interarrival and service time distributions, operating under the join-the-shortest-queue and power-of-two-choices policies. Under a weaker set of assumptions than those commonly found in the literature, we prove that the scaled steady-state queue length at each station converges weakly to an identical exponential random variable in heavy traffic. Specifically, our results hold under the assumption of the $(2 + δ_0)$th moment for the interarrival and service distributions with some $δ_0 > 0$. The proof leverages the Palm version of the basic adjoint relationship (BAR) as a key technique.

description: Temperature and light are key climatic factors which affect grapevine physiology in the growing season. Our aim was to investigate the interactive effects of temperature and light intensity on reproductive growth responses of 'Shiraz' vines in vineyard conditions. Well-watered vines were covered with no shade, light, medium and heavy shade covers in a vineyard over three consecutive seasons. Several heat events, i.e., air temperatures exceeding 40 °C for several days, occurred in two of the seasons. Heavy shade reduced canopy temperatures by 3.2-6 °C in the cooler season and by 4-6 °C in the warmer seasons, relative to air temperature and compared with the open canopy. The onset of berry growth was delayed by the heavy shade but the rate of sugar accumulation was not affected. During the season with the most severe heat events, berry dry matter accumulation was significantly higher in the shaded treatments compared to the unshaded vines. The hypothesis was confirmed that medium and heavy shade conferred high levels of protection on the berry ripening process from high summer temperatures and the concurrent exposure to light intensities.

description: An analytical technique to accurately measure iron isotope amount ratios by multi collector inductively coupled plasma mass spectrometer was developed. The analytical technique consisted of sample purification using ion exchange chromatography and measurement by the mass spectrometer. Numerous factors affecting the measured data including magnet stability, and chromium interferences were encountered during development. At the completion of this projects, the precision in δ(56/54Fe) is 0.09 ‰. Iron isotope measurements were completed on three data sets: a source identification study for the Cardium formation, anoxic brine samples from Lake Vida and a bioremediation study for Nova Chemicals. For the Cardium formation no definite source of iron can be identified based solely on the iron data. Similarly with the Lake Vida samples, three possible mechanisms are discussed which could produce the unique δ(56/54Fe) values. For the bioremediation study, the data highlight difficulties during sample acquisition and improvements to sample acquisition are suggested.

description: We propose a lattice action for the overlap Dirac matrix with nonzero chemical potential which is shown to preserve the chiral invariance on the lattice exactly. We further demonstrate it to arise from the Domain wall by letting the chemical potential count only the physically relevant wall modes.

description: Manufacturing and engineering organisations store data about equipment in relational databases. Sets of labels used to identify table contents are often specific to an individual company and identical equipment is often described by different labels in different databases across a single company. This situation limits automatic use and reuse of data from different data sets and the exchange of data across organisations, such as between operators of equipment and those that supply or service the equipment. Industry associations and Standards bodies have been active in developing dictionaries, taxonomies and reference data libraries (collectively called Knowledge Organisation Systems) to assist with this issue. These KOS are informed by a substantial knowledge base regarding equipment. There are many KOS to choose from and as a result a new challenge: which KOS(s) to use, and why? This paper describes a number of equipment-related KOS from 1) Engineering Standards including the ISO/IEC common data dictionary (CDD), ISO 15926-4 reference data library for process plants, IFC classes, and MIMOSA Common Conceptual Object Model for asset life data exchange, 2) hierarchical equipment coding systems including the Harmonised System (HS) used for classification of traded products, Common Procurement Vocabulary codes developed by the European Union, Electropedia (a.k.a International Electrotechnical vocabulary) developed by the IEC, and 3) Open source knowledge bases including ConceptNet, and Wikidata. For each KOS technical and practical metadata are provided. The goal of this paper is to support engineers to make informed decisions about which KOS to use, specifically for describing assets and their asset hierarchy.

description: Governments have increasingly been embarking on substantial waves of educational reform in an attempt to develop more effective school systems and raise levels of student learning and achievement. Some jurisdictions appear to be more successful than others at shifting their professional learning focus onto research-informed practice to create and apply new knowledge and expand teachers’ repertoires of instructional practices within their complex knowledge-producing and knowledge-disseminating systems. The following study, an exploratory multi-case study of four high-performing Alberta school divisions, as determined by provincial accountability pillars, offers insight into how leaders mobilize knowledge to align research and learning practice within their complex social systems. The findings lend credence to the notion that a systems or complexity approach can play a role in understanding the unpredictability of organizational change and thereby enhance the mobilization of knowledge regarding the alignment of research and learning practice. Through a grounded theory approach, a conceptual framework emerged, built upon the complex interplay of three facets: (1) enhancing student learning, (2) ensuring best practice and research, and (3) establishing relational trust. These three facets are brought to fruition through a focus on five key dimensions: (1) efficaciously decentralizing: attending to both redundancy and diversity, (2) explicitly focusing: identifying sites of redundancy, (3) enacting expectations: implementing strategies for redundancy, (4) engaging expertise: identifying sites of diversity, and (5) ensuring efficacy: implementing strategies for diversity. The framework, while not definitive, contributed to the emerging picture of knowledge mobilization and the role that complexity theory can play in understanding and enhancing knowledge mobilization, a complex emergence phenomenon, with regard to aligning research and practice within self-organizing, self-maintaining, adaptive, learning systems such as school jurisdictions. By attending to both redundancy and diversity, leaders are able to prompt the emergence of a social collective intelligence within distinguishable but intimately intertwined networks and displace the individual as the sole site of learning, and intelligence creativity.

description: The global pandemic caused by Coronavirus 19 (SARS-CoV-19) has spread rapidly and affected the entire world with the maximum number of cases reported from the United States, India and Brazil. Coronavirus 19 (SARS-CoV-19) has infected a total of 31,664,104 people and caused 972,221 deaths according to the WHO data as on 24 September 2020 [1]. Globally, the age- normalized death rate due to cardio-vascular disease (CVD) is 272 per one lakh population and in India, it is 235 per one lakh population on an average [2]. People with heart diseases are twelve times more prone to die and six times more prone to be hospitalized due to severe coronavirus disease (Covid-19) than healthy people [3]. Covid 19 disease mainly affects the respiratory system, and other extra-pulmonary complications are acute renal injury, gastrointestinal consequences, hepatocellular damage, hyperglycemia, ketosis, ocular complications, dermatologic manifestations, thrombotic sequelae, acute coronary syndromes, myocardial dysfunction and arrhythmia, neurological illnesses, etc. [4]. Acute cardiac injury is the commonest covid related cardiac abnormality affecting 8-12% of all patients [5]. Elevated level of cardiac troponin is described as acute cardiac injury [6]. Coronavirus leads to increased pro-inflammatory markers, T-lymphocyte-mediated cytotoxicity, increased sympathetic activity, rupture of plaque, myocardial cell invasion and direct myocardial damage augmented by the cytokine storm syndrome. COVID-19 related cardiovascular complications includes acute cardiac injury, acute coronary event, left ventricular systolic dysfunction, acute left ventricular failure, diastolic dysfunction [7], brain medullary cardiorespiratory dysfunction and congestive heart failure (CHF) [8-12], ST-segment elevated myocardial infarction, cardiogenic shock, diffuse myocardial edema, pericarditis, pericardial effusion, cardiac tamponade, venous thromboembolism, and cardiomyopathies mimicking STEMI presentations, sinus bradycardia [13], arrhythmia, cardiac conduction abnormalities [14] and sudden death [15]. Sufficient understanding of the COVID-19 effect on cardiovascular system is important for optimum treatment of covid affected patients and to prevent morbidity and mortality in the patients. The pathophysiology of myocardial complications is still speculative and hence, we have tried to decode the cardiovascular pathophysiology in Covid 19 infection.
