Authors: Andersson Leif Erik , Anaya‐Lara Olimpo , Tande John Olav , Merz Karl Otto , Imsland Lars 
Published: April 2021

AbstractWind farm control design is a recently new area of research that has rapidly become a key enabler for the development of large wind farm projects and their safe and efficient connection to the power grid. A comprehensive review of the intense research conducted in this area over the last 10 years is presented. Part I reviews control system concepts and structures and classifies them depending on their main objective (i.e. to maximise power production or to provide grid services. The work and key findings in each paper are discussed in detail with particular emphasis on the turbine side. Additionally, the review contributes to the existing reviews on the area by providing an elegant classification between model testing and control approaches. Areas where significant work is still needed are also discussed. In Part II, a thorough review on aerodynamic wind farm models for control design purposes is provided.

Zusammenfassung
Hintergrund Trotz einer hohen Zahl an Abschlüssen in der
Humanmedizin ist in Deutschland immer häufiger von einem
Ärztemangel die Rede. Ein Grund ist die schwierige Vereinbarkeit von
Kliniktätigkeit und Familienleben, die vor allem Ärztinnen
als Hauptgrund für die spätere Arbeit im nicht-kurativen
Bereich nennen.
Ziel der Arbeit Die vorliegende Arbeit befasst sich mit dem Einfluss
des Elternstatus von Ärztinnen und Ärzten auf ihre
Karriereentwicklung und das Belastungserleben am Ende der Weiterbildung.
Darüber hinaus betrachtet werden die Auswirkungen von befristeten
Arbeitsverträgen und erlebter Unterstützung durch den
Partner auf das Belastungserleben.
Material und Methoden Es wurden die Daten der KarMed-Studie, welche
sich mit Karriereverläufen von Ärztinnen und Ärzten
während der fachärztlichen Weiterbildung
beschäftigt, ausgewertet. Die vorliegende Arbeit befasst sich mit
der querschnittlichen Analyse des Erhebungszeitraums von Oktober 2015 bis
Mai 2016. Zu diesem befanden sich 433 StudienteilnehmerInnen am Ende ihrer
Weiterbildung. Eingesetzt wurden u. a. die Fragebögen
Work-Family Conflict und Family-Work Conflict Skalen.
Ergebnisse Ärztinnen mit Kind unterbrechen die Weiterbildung
fünfmal häufiger als ihre Kolleginnen ohne Kind und
achtzehnmal häufiger als Ärzte mit Kind. Ärztinnen
mit Kind sowie Ärzte mit Kind weisen signifikant höhere
Werte auf der Family-Work Conflict Skala auf, Ärztinnen ohne Kind
hingegen höhere Werte auf der Work-Conflict Skala. Bei
Ärzten zeigt sich kein signifikanter Unterschied auf der Work-Family
Skala. Weder ein befristeter Arbeitsvertrag noch die Verteilung von
Kinderbetreuung zwischen Ärztinnen/Ärzten und ihren
Partnern/-rinnen haben einen signifikanten Einfluss auf das
Belastungserleben zur Folge.
Schlußfolgerung Es besteht ein Bedarf die Konflikte, die aus
dem Familienleben auf das Arbeitsleben wirken insbesondere für
Ärztinnen in Weiterbildung zu reduzieren.

Pandemics: Historically Slow “Learning Curve” Leading to Biomedical Informatics and Vaccine Breakthroughs
Authors: Kulikowski Casimir A. 
Published: April 2021

Background: The worldwide tragedy of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic vividly demonstrates just how inadequate mitigation and control of the spread of infectious diseases can be when faced with a new microorganism with unknown pathogenic effects. Responses by governments in charge of public health, and all other involved organizations, have proved largely wanting. Data infrastructure and the information and communication systems needed to deal with the pandemic have likewise not been up to the task. Nevertheless, after a year of the worldwide outbreak, hope arises from this being the first major pandemic event in history where genomic and related biosciences – relying on biomedical informatics – have been essential in decoding the viral sequence data and producing the mRNA and other biotechnologies that unexpectedly rapidly have led to investigation, design, development, and testing of useful vaccines. Medical informatics may also help support public health actions and clinical interventions - but scalability and impact will depend on overcoming ingrained human shortcomings to deal with complex socio-economic, political, and technological disruptions together with the many ethical challenges presented by pandemics.Objectives: The principal goal is to review the history of biomedical information and healthcare practices related to past pandemics in order to illustrate just how exceptional and dependent on biomedical informatics are the recent scientific insights into human immune responses to viral infection, which are enabling rapid antiviral vaccine development and clinical management of severe cases – despite the many societal challenges ahead.Methods: This paper briefly reviews some of the key historical antecedents leading up to modern insights into epidemic and pandemic processes with their biomedical and healthcare information intended to guide practitioners, agencies, and the lay public in today’s ongoing pandemic events.Conclusions: Poor scientific understanding and excessively slow learning about infectious disease processes and mitigating behaviors have stymied effective treatment until the present time. Advances in insights about immune systems, genomes, proteomes, and all the other -omes, became a reality thanks to the key sequencing technologies and biomedical informatics that enabled the Human Genome Project, and only now, 20 years later, are having an impact in ameliorating devastating zoonotic infectious pandemics, including the present SARS-CoV-2 event through unprecedently rapid vaccine development. In the future these advances will hopefully also enable more targeted prevention and treatment of disease. However, past and present shortcomings of most of the COVID-19 pandemic responses illustrate just how difficult it is to persuade enough people – and especially political leaders – to adopt societally beneficial risk-avoidance behaviors and policies, even as these become better understood.

Published: April 2021

AbstractThere has been concern whether the declining cases of ST-segment elevation myocardial infarction (STEMI) during the coronavirus disease 2019 (COVID-19) outbreak associate with primary angioplasty performance.We assessed the performance of primary angioplasty in a tertiary care hospital in Jakarta, Indonesia, by comparing the door-to-device (DTD) time and thrombolysis in myocardial infarction (TIMI) flow after angioplasty between two periods of admission: during the outbreak of COVID-19 (March 1 to May 31, 2020) and before the outbreak (March 1, to May 31, 2019).Overall, there was a relative reduction of 44% for STEMI admission during the outbreak (n = 116) compared with before the outbreak (N = 208). Compared with before the outbreak period (n = 141), STEMI patients who admitted during the outbreak and received primary angioplasty (n = 70) had similar median symptom onset-to-angioplasty center admission (360 minutes for each group), similar to radial access uptake (90 vs. 89.4%, p = 0.88) and left anterior descending infarct-related artery (54.3 vs. 58.9%, p = 0.52). The median DTD time and total ischemia time were longer (104 vs. 81 minutes, p < 0.001, and 475.5 vs. 449 minutes, p = 0.43, respectively). However, the final achievement of TIMI 3 flow was similar (87.1 vs. 87.2%), and so was the in-hospital mortality (5.7 vs. 7.8%).During the COVID-19 outbreak, we found a longer DTD time for primary angioplasty, but the achievement of final TIMI 3 flow and in-hospital mortality were similar as compared with before the outbreak. Thus, primary angioplasty should remain the standard of care for STEMI during the COVID-19 outbreak.

AbstractObjective The objective of the study was to characterize the completeness and concordance of the electronic health record (EHR) documentation of cancer symptoms among multidisciplinary health care professionals.Methods We examined the EHRs of children, adolescents, and young adults who received highly emetogenic chemotherapy and characterized the completeness and concordance of chemotherapy-induced nausea and vomiting (CINV) documentation by clinician type and by the International Classification of Diseases 10th Revision (ICD-10) coding choice.Results The EHRs of 127 patients, comprising 870 patient notes, were abstracted and reviewed. A CINV assessment was documented by prescribers in 75% of patients, and by nurses in 58% of patients. Of the 60 encounters where both prescribers and nurses documented, 72% agreed on the presence/absence of CINV.Conclusion Most patients receiving highly emetogenic chemotherapy had a documented assessment of CINV; however, many had incomplete or discordant documentation of CINV from different providers by role, implying the importance of incorporating pragmatic knowledge of EHR documentation patterns among multidisciplinary health professionals for EHR phenotyping and clinical decision support systems directed toward cancer-related symptom management.
High-bandwidth modeling for rate-dependent hysteresis nonlinearity using a standard Prandtl–Ishlinskii model
Authors: Yang Haigen , Zhu Wei , Liu Feifei 
Published: April 2021

Rate-dependent hysteresis of piezoelectric stack actuators (PSAs) is known to cause oscillations and instabilities. This paper introduces a novel electro-mechanical coupling model that can accurately characterize the high-bandwidth rate-dependent hysteresis of a PSA. The proposed model contains three components to fully represent the output response of the system, namely, an electric model that is used to describe the electric dynamic behaviors of the PSA and its power amplifier, a hysteresis model that is applied to represent the inverse piezoelectric effect, and a mechanical model that is able to characterize the mechanical dynamic behavior of the PSA. It should be noted that, in the mechanical model, the force generated by the inverse piezoelectric effect of piezoelectric wafers is considered a distributed force and the dynamic model of the PSA is regarded as a longitudinal vibration straight bar with a uniform cross section. Through this proposed model, high modeling accuracy is achieved well with high-bandwidth varying frequencies (1–1000 Hz) as well as varying amplitudes. This paper provides a simple and effective novel method for the high-bandwidth modeling of smart material-based actuators with rate-dependent hysteresis nonlinearity.
Seed production and grow-out of climbing perch (Anabas testudineus) in Vietnam.
Authors: Pham Van Khanh 
Published: April 2021

Abstract

Broodfish conditioning of climbing perch (Anabas testudineus) is conducted in earthen ponds with a density of 2-4 kg m-2, at a 1:1 male to female ratio. Homemade or commercial feeds containing 22-25% crude protein are given as feed for the broodfish. To induce spawning, HCG and LH-RHa are used. Nursing from fry to fingerlings is done in earthen ponds with densities of 500-600 fry m-2. After nursing for 50-60 days, when the fish reach 4-5 cm length, they are harvested and stocked in grow-out systems. Fingerlings are stocked in grow-out ponds at a density of 20 fish m-2. Homemade and commercial feeds containing 22-25% crude protein are used to feed fish. After 6 months, the fish can reach the marketable size of 60-100 g per fish. The stocking density of fish in rice fields is lower, at 3 m-2. They feed on natural food found in the rice field. Homemade feeds are also added as supplementary feed. Rice-fish culture covers two continuous paddy rice cropping periods, or one paddy rice crop and one flooded crop.
System understanding as a scientific foundation in radioactive waste disposal, legacy site and decommissioning programmes
Authors: Lindborg Tobias , Ikonen Ari T K , Kautsky Ulrik , Smith Graham 
Published: April 2021

Abstract
Ongoing national programmes and International forums have in recent decades developed and enhanced methods and strategies in how to address the characterisation of potentially suitable sites for radioactive waste repositories. Siting processes, site selection and site investigation programmes have been conducted for near surface and geological repositories and plans for construction are in progress or have already been implemented. Lessons learned from these national and international programmes are available and results are published. In this paper we synthesise the methods and our lessons learned in how to plan, conduct, and achieve site understanding. Effective site understanding should incorporate a multi-disciplinary and integrated view of geosphere and biosphere information for a site, together with the designed parts of a repository or installation that constitute the total system. We argue that this integrated approach, following a staged program of repository development and adopting a graded approach to assessment at each stage, is to be recommended. The recommendation is supported by the results of international cooperation and progress with national programmes (e.g. the Swedish SKB). Further, we argue that this strategy is valid as a foundation for planning and execution of other types of radioactive waste management programmes such as decommissioning, legacy site management and remediation projects.
Power spectrum in stochastic inflation
Authors: Ando Kenta , Vennin Vincent 
Published: April 2021

Abstract
We compute the power spectrum of curvature perturbations in stochastic inflation. This combines the distribution of first crossing times through the end-of-inflation surface, which has been previously studied, with the distribution of the fields value at the time when a given scale crosses out the Hubble radius during inflation, which we show how to compute. This allows the stochastic-δ N formalism to make concrete contact with observations. As an application, we study how quantum diffusion at small scales (arising e.g. in models leading to primordial black holes) affects the large-scale perturbations observed in the cosmic microwave background. We find that even if those sets of scales are well separated, large effects can arise from the distortion of the classical relationship between field values and wavenumbers brought about by quantum diffusion near the end of inflation. This shows that cosmic microwave background measurements can set explicit constraints on the entire inflationary potential down to the end of inflation.
Dark sector production and baryogenesis from not quite black holes *
Authors: Aydemir Ufuk , Ren Jing 
Published: April 2021

Abstract
Primordial black holes have been considered attractive dark matter candidates, whereas some of the predictions rely heavily on the near-horizon physics that remains to be tested experimentally. As a concrete alternative, thermal 2-2-holes closely resemble black holes without event horizons. Being a probable endpoint of gravitational collapse, they provide a solution to the information loss problem but also naturally result in stable remnants. Previously, we have considered primordial 2-2-hole remnants as dark matter. Owing to the strong constraints from a novel phenomenon associated with remnant mergers, only small remnants with mass approximate to the Planck mass can constitute all dark matter. In this paper, we examine the scenario in which the majority of dark matter consists of particles produced by the evaporation of primordial 2-2-holes, whereas the remnant contribution is secondary. The products with sufficiently light mass may contribute to the number of relativistic degrees of freedom in the early universe, which we also calculate. Moreover, 2-2-hole evaporation can produce particles that are responsible for the baryon asymmetry. We observe that baryogenesis through direct B-violating decays or through leptogenesis can both be realized. Overall, the viable parameter space for the Planck remnant scenario is similar to that of primordial black holes with Planck remnants. However, heavier remnants result in different predictions, and the viable parameter space remains large even when the remnant abundance is small.

Abstract
SOLPS-ITER simulations of the European DEMO reactor with a Super-X divertor, which has larger major radius at the outer target and increased connection length, show an increased operational space for divertor power exhaust compared to the conventional single-null configuration. Using a multi-fluid approach with fluid neutrals and charge-state bundling of impurities, we assessed the existence and boundaries of the operational space in the single-null and Super-X configurations by carrying out fuelling, seeding and power scans. Compared to the conventional single-null divertor, the Super-X divertor offers lower impurity concentration (factor ∼2 lower) at the same main plasma density, and consistent with this, it has lower main plasma density at the same impurity concentration level. This observed difference is in line with the simple analytical Lengyel model predictions resulting from the increased connection length in the super-X configuration. DEMO with a Super-X divertor demonstrates remarkable robustness against increases in input power, and in this study is able to exhaust the maximum expected steady-state separatrix-crossing power of 300 MW while maintaining acceptable impurity concentration along the separatrix This is something that was not possible in the single-null configuration in this study. This robustness of the Super-X divertor lies mostly in its capability to sufficiently dissipate power in its divertor via argon (Ar) radiation at acceptable Ar concentration, which is related to two factors: long (with respect to single-null) parallel connection length from the upstream to the outer target and higher but tolerable extrinsic impurity concentration at higher input powers. Finally, consistent with neon-seeded simulations of ITER, it is observed in all our simulations that the plasma density drops with increasing Ar concentration given fixed power input. We find that as the Ar content increases, the accompanying enhancement of Ar radiation reduces the power available for deuterium (D) to be ionized, thus limiting the D ionization particle source, and consequently reducing the plasma density.
Identification of male and female nutmeg seeds based on the shape and texture features of leaf images using the learning vector quantization (LVQ)

Published: April 2021

Abstract
One of the stages in the process of planting nutmeg seedlings on agricultural land is the identification of the sex of male and female nutmeg seedlings. The process of identifying nutmeg seedlings still uses manual methods, while the method is often inaccurate and inefficient. There fore, this research discusses the methods and results of identification of male and female nutmeg seedling leaves based on the combined feature extraction and leaf texture using learning vector quantization (LVQ). The form feature extraction method used consists of slimness, roundness, narrow factor, perimeter ratio and diameter, perimeter ratio at length while for texture is contrast, correlation, energy, and homogeneity. The results of the combined extraction of shape and texture features were applied as input vectors when classification using the LVQ method. Whereas LVQ aims at classification based on extraction results, by initializing LVQ parameters, namely learning rate and epoch. The change in the learning rate value on LVQ is very influential to get the percentage of the correctness of the data, the learning rate value must be between 0 to 1. The accuracy of LVQ predictions obtained in this study is 92.30%, with the best learning rate values from 0.001 to 0.09 and epoch 50.
