Stability enhancement of induction generator–based series compensated wind power plants by alleviating subsynchronous torsional oscillations using BFOA‐optimal controller tuned STATCOM
Authors: Kumar Rajeev , Singh Rajveer , Ashfaq Haroon 
Published: May 2020

AbstractIn this paper, a STATCOM (static synchronous compensator) is used to encounter the potential SSR (subsynchronous resonance) observed by IG (Induction Generator) based series compensated wind farms. The basic controller used for STATCOM control is identical to that of the literature. An idea of a unique meta‐heuristic swarm‐based optimization technique called BFOA (bacterial foraging optimization algorithm) based optimal‐controller is introduced for optimal parameter selection of the basic controller used in the control scheme of the STATCOM. The investigation is carried out with 500 MW IG‐based wind farm exposed to three‐phase LLL‐G fault close to the PCC (point of common coupling) and implemented with MATLAB in both steady and transient states for the three different cases, namely, without STATCOM, with the basic STATCOM controller, and in the presence of the proposed BFOA‐optimal controller‐based STATCOM. In both the states, the observed eigenvalues of the test system, together with the time domain results of the generator rotor dynamics for three distinct cases, reveals the effectiveness of the suggested BFOA‐optimal controller tuned STATCOM in mitigating the potential SSR.
Forced vibrations of functionally graded annular and circular plates by domain‐boundary element method
Authors: Eshraghi Iman , Dag Serkan 
Published: May 2020

AbstractAxi‐symmetric dynamic response of functionally graded circular and annular Mindlin plates with through‐the‐thickness variations of physical properties is investigated by a new domain‐boundary element formulation. Three governing partial differential equations of motion of the inhomogeneous plate are converted to integral equations by utilizing the static fundamental solutions of the displacement components. These integral equations are then spatially discretized by dividing the entire domain into a number of cells and incorporating suitable shape functions to approximate the variation of unknown parameters across the cells. The resulting set of ordinary differential equations in time are then solved by the Houbolt method. To verify the accuracy of the developed procedure, dynamic responses generated for a homogeneous plate are compared to those calculated through an analytical solution. Different loading conditions such as step, harmonic, and impulsive loadings are considered for generation of numerical results of dynamic responses of functionally graded circular and annular plates. Convergence characteristics and effects of material inhomogeneity, and geometric parameters are extensively investigated. It has been shown that the presented method is a fast and accurate and technique in elastodynamic analysis of functionally graded plates.
Conformal Mappings Revisited in the Octonions and Clifford Algebras of Arbitrary Dimension
Authors: Kraußhar Rolf Sören 
Published: May 2020

AbstractIn this paper we revisit the concept of conformality in the sense of Gauss in the context of octonions and Clifford algebras. We extend a characterization of conformality in terms of a system of partial differential equations and differential forms using special orthonormal sets of continuous functions that have been used before in the particular quaternionic setting. The aim is to describe to which higher dimensional algebras this characterization can exactly be extended and under which circumstances. It turns out to be crucial that this characterization requires a domain of definition that lies in a subalgebra that has the norm composition property and that is either associative (Clifford algebra case) or at least alternative (octonionic case). The orthonormal frames are elements of the spin group Spin$$(n+1)$$(n+1). We round off by relating the nature of the orthonormal frames to the associated Möbius transformation which are related toSO(9, 1) in the octonionic case and to the Ahlfors–Vahlen group in the case of a Clifford algebra.

AbstractObjectiveTo investigate the association between gut microbiome with breast tumor characteristics (receptor status, stage and grade) and known breast cancer risk factors.MethodsIn a pilot cross-sectional study of 37 incident breast cancer patients, fecal samples collected prior to chemotherapy were analyzed by 16S ribosomal RNA (rRNA) gene-based sequencing protocol. Alpha diversity and specific taxa by tumor characteristics and breast cancer risk factors were tested by Wilcoxon rank sum test, and by differential abundance analysis, using a zero-inflated negative binomial regression model with adjustment for total counts, age and race/ethnicity.ResultsThere were no significant alpha diversity or phyla differences by estrogen/progesterone receptor status, tumor grade, stage, parity and body mass index. However, women with human epidermal growth factor receptor 2 positive (HER2+) (n = 12) compared to HER2− (n = 25) breast cancer showed 12–23% lower alpha diversity [number of species (OTU)p = 0.033, Shannon indexp = 0.034], lower abundance ofFirmicutes(p = 0.005) and higher abundance ofBacteroidetes(p = 0.089).Early menarche (ages ≤ 11) (n = 11) compared with later menarche (ages ≥ 12) (n = 26) was associated with lower OTU (p = 0.036), Chao1 index (p = 0.020) and lower abundance ofFirmicutes(p = 0.048). High total body fat (TBF) (> 46%) (n = 12) compared to lower (≤ 46%) TBF was also associated with lower Chao 1 index (p = 0.011). There were other significant taxa abundance differences by HER2 status, menarche age, as well as other tumor and breast cancer risk factors.Conclusions and relevanceFurther studies are needed to identify characteristics of the human microbiome and the interrelationships between breast cancer hormone receptor status and established breast cancer risk factors.
Predictive risk factors of complications in different breast reconstruction methods
Authors: Palve J. S. , Luukkaala T. H. , Kääriäinen M. T. 
Published: May 2020

Abstract
Purpose
Women with different BMI, age and comorbidities seek for breast reconstruction. It is critical to understand the risk associated with each technique to ensure the most appropriate method and timing is used. Outcome after reconstructions have been studied, but consensus is lacking regarding predictive risk factors of complications. The authors present their experience of different autologous and alloplastic reconstructions with an emphasis on predictors of complications.

Methods
Prospectively maintained reconstruction database from 2008 to 2019 was reviewed. Factors associated with complications were identified using logistic regression, multinomial logistic regression and risk factor score to determine predictors of complications.

Results
A total of 850 breast reconstructions were performed in 793 women, including 447 DIEP, 283 LD, 12 TMG and 51 implant reconstructions. Complications included minor (n = 231, 29%), re-surgery requiring (n = 142, 18%) and medical complications (n = 7, 1%). Multivariable analysis showed that complications were associated independently with BMI > 30 (OR 1.59; 95% CI 1.05–2.39, p = 0.027), LD technique (OR 4.05; 95% CI 2.10–7.81, p < 0.001), asthma or chronic obstructive pulmonary disease (OR 2.77; 95% CI 1.50–5.12, p = 0.001) and immediate operation (OR 0.69; 95% CI 0.44–1.07, p = 0.099). Each factor contributed 1 point in the creation of a risk-scoring system. The overall complication rate was increased as the risk score increased (35%, 61%, 76% and 100% for 1, 2, 3 and 4 risk scores, respectively, p < 0.001).

Conclusions
The rate of complication can be predicted by a risk-scoring system. In increasing trend of patients with medical problems undergoing breast reconstruction, tailoring of preventive measures to patients’ risk factors and careful consideration of the best timing of reconstruction is mandatory to prevent complications and costs.
The Legal Regulation of Non-stun Slaughter: Balancing Religious Freedom, Non-discrimination and Animal Welfare
Authors: Wills Joe 
Published: May 2020

AbstractIn February 2019, The Royal Society for the Prevention of Cruelty to Animals (RSPCA) and the British Veterinary Association (BVA) published a joint open letter to the British Government calling for a repeal of a legal exemption that permits the slaughter of animals without prior stunning. The RSPCA and BVA argue that repealing the exemption is required on grounds of animal welfare, claiming that non-stun slaughter causes unnecessary pain and suffering. By contrast, Islamic and Jewish groups assert that non-stun slaughter, when properly conducted, is both humane and a religious requirement for least some followers of their faiths. This article considers whether imposing a ban on non-stun slaughter is compatible with obligations to protect religious freedom and non-discrimination under the European Convention of Human Rights. It will conclude that it can be and, when done to protect animal welfare, falls within Contracting States’ margin of appreciation.

Published: May 2020

AbstractFragments of four candidate reference genes of Aphelenchoides besseyi, including actin, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ubiquitin conjugating-3 enzyme (UBC) and alpha-tubulin (α-tubulin) were cloned from the transcriptome database of A. besseyi. The expression level of these four candidate reference genes and a commonly used reference gene of A. besseyi (18S rRNA) in three experimental conditions, including the four life stages (female, male, juvenile and egg) of two populations and the mixed-stage nematodes of four populations with different origins and hosts were analyzed by RT-qPCR. The expression stability of the five candidate reference genes under the three experimental conditions was analyzed by ΔCt, geNorm, NormFinder and RefFinder respectively. The analysis results of ΔCt, geNorm, NormFinder and RefFinder all indicated that UBC was the gene with the highest average ranking of stability. In conclusion, the expression stability of UBC was optimal under the three experimental conditions, indicating that UBC could be used as a suitable reference gene instead of 18S rRNA in the RT-qPCR analysis for A. besseyi.

Abstract
Purpose
Since 2011, the evidence-based KLIK Patient Reported Outcome Measure (PROM) portal has been implemented in clinical practice in > 20 Dutch hospitals. Patients and/or parents complete PROMs on Health Related Quality of Life, symptoms and psychosocial functioning before their outpatient consultation. Answers are converted into an ePROfile and discussed by clinicians during consultation to monitor well-being over time and detect problems early. This study aims to get insight into the KLIK implementation from the clinician’s perspective.

Methods
As part of the KLIK implementation process, annual meetings were held with multidisciplinary teams to evaluate the use of KLIK. An online questionnaire was sent regarding (1) overall satisfaction, (2) feeling competent to discuss PROMs, (3) use of KLIK during the consultation, (4) influence of KLIK on the consultation, (5) usability of the KLIK PROM portal, (6) satisfaction with PROMs and feedback, and (7) support of the KLIK expert team. Open questions about (dis)advantages were included. Descriptive analyses were used.

Results
One hundred and forty-eight clinicians (response-rate 61%) from 14 hospitals in the Netherlands participated. Results show that: (1) clinicians report an overall satisfaction of median = 69/100 (visual analogue scale), (2) 85.8% feel competent discussing the ePROfile, (3) 70.3% (almost) always discuss the ePROfile, (4) 70.3% think that KLIK improves consultation, (5) 71.6% think KLIK is easy to use, (6) 80.4% are satisfied with the feedback of the overall KLIK ePROfile, (7) 71.6% experience sufficient support of the KLIK team.

Conclusion
Participating clinicians are generally satisfied with KLIK. Improvements to the KLIK PROM portal are now realized based on the mentioned disadvantages (e.g., shorten PROM completion by use of PROMIS and integrating KLIK with Electronic Health Records).
The rivalry between Bernini and Borromini from a scientometric perspective
Authors: Wieland Martin , Gorraiz Juan 
Published: May 2020

AbstractFrom a historical point of view, Rome and especially the University of La Sapienza, are closely linked to two geniuses of Baroque art: Bernini and Borromini. In this study, we analyze the rivalry between them from a scientometric perspective. This study also serves as a basis for exploring which data sources may be appropriate for broad impact assessment of individuals and/or celebrities. We pay special attention to encyclopaedias, library catalogues and other databases or types of publications that are not normally used for this purpose. The results show that some sources such as Wikipedia are not exploited according to the possibilities they offer, especially those related to different languages and cultures. Moreover, analyses are often reduced to a minimum number of data sources, which can distort the relevance of the outcome. Our results show that other sources normally not considered for this purpose, like JSTOR, PQDT, Google Scholar, Catalogue Holdings, etc. can provide more relevant or abundant information than the typically used Web of Science Core Collection and Scopus. Finally, we also contrast opportunities and limitation of old and new (YouTube, Twitter) data sources (particularly the aspects quality and accuracy of the search methods). Much room for improvement has been identified in order to use data sources more efficiently and with higher accuracy.

Published: May 2020

AbstractThe effect of pulsed light (PL) on numerous important quality characteristics of pineapple juice was studied and compared with untreated and thermally pasteurised samples. The laboratory scale PL batch system used was operated with each three different voltages (1.8, 2.1, and 2.4 kV) and numbers of pulses (47, 94, and 187). Treatments with 2.4 kV and either 94 or 187 pulses (757/1479 J·cm−2) resulted in a 5-log reduction in aerobic mesophiles and the yeast and mould counts. Peroxidase was more resistant to PL than polyphenol oxidase, whereas the bromelain activity was completely retained in all PL-treated juices. Colour and antioxidant capacity were minimally affected, while vitamin C, genuine pineapple furanones, and phenolic compounds declined. In contrast, thermal pasteurisation was more detrimental to colour, antioxidant capacity, and vitamin C content, but resulted in a superior inactivation of microorganisms and enzymes and retention of phenolic compounds. Principal component analysis (PCA) permitted the differentiation of fresh, thermally pasteurised, and all PL-treated juices. PCA on the basis of the individual juice constituents additionally arranged the latter juices according to the number of pulses and voltage levels applied, particularly promoted by the oxidation of ascorbic to dehydroascorbic acid. In conclusion, PL treatment represents a promising new alternative to conventional thermal preservation techniques, whereby the inactivation of deteriorative enzymes may be further optimised.

AbstractSulfatides might accelerate atherothrombosis. Therefore, this study aimed to monitor serum sulfatide levels in coronary arteries across atheromatous plaques during percutaneous coronary intervention (PCI) with either drug-eluting stents or drug-coated balloons. From every patient, we collected blood from points 1 and 2 before PCI, and points 3 and 4 15 min after PCI, where odd numbered points were proximal and even numbered points were distal to a stenotic lesion. Patients were separated into two groups on the basis of the requirement of a pre-balloon dilation technique (pre-BD) before collecting samples at point 2. This was because of difficulty in passing a microcatheter through narrowed lumens around atheromatous lesions. In patients without pre-BD (n = 23), mean serum sulfatide levels at points 2 (4.60 ± 4.04 nmol/mL), 3 (4.35 ± 3.76 nmol/mL), and 4 (4.53 ± 3.26 nmol/mL) were significantly higher than those at point 1 (2.49 ± 1.11 nmol/mL; all p < 0.05). Patients with pre-BD (n = 18) required additional time (15–20 min) for collecting samples at points 2 to 4 compared with those without pre-BD, but there was no significant difference between the groups. The reason for this lack of significance is not known but may be due (at least in part) to diffusion of sulfatides in the circulation caused by the extra time needed for collection. These results suggest that accumulated sulfatides in stenotic plaques evoke atherothrombosis because of the thrombogenic property of sulfatides under pathological conditions.
Geospatial simulations of airborne ice-penetrating radar surveying reveal elevation under-measurement bias for ice-sheet bed topography

Published: May 2020

AbstractAirborne radio-echo sounding (RES) surveys are widely used to measure ice-sheet bed topography. Measuring bed topography as accurately and widely as possible is of critical importance to modelling ice dynamics and hence to constraining better future ice response to climate change. Measurement accuracy of RES surveys is influenced both by the geometry of bed topography and the survey design. Here we develop a novel approach for simulating RES surveys over glaciated terrain, to quantify the sensitivity of derived bed elevation to topographic geometry. Furthermore, we investigate how measurement errors influence the quantification of glacial valley geometry. We find a negative bias across RES measurements, where off-nadir return measurement error is typically −1.8 ± 11.6 m. Topographic highlands are under-measured an order of magnitude more than lowlands. Consequently, valley depth and cross-sectional area are largely under-estimated. While overall estimates of ice thickness are likely too high, we find large glacier valley cross-sectional area to be under-estimated by −2.8 ± 18.1%. Therefore, estimates of ice flux through large outlet glaciers are likely too low when this effect is not taken into account. Additionally, bed mismeasurements potentially impact our appreciation of outlet-glacier stability.
Total cost of surgical site infection in the two years following primary knee replacement surgery
Authors: Lethbridge Lynn N. , Richardson C. Glen , Dunbar Michael J. 
Published: May 2020

AbstractObjective:The disease burden of surgical site infection (SSI) following total knee (TKA) replacement is considerable and is expected to grow with increased demand for the procedure. Diagnosing and treating SSI utilizes both inpatient and outpatient services, and the timing of diagnosis can affect health service requirements. The purpose of this study was to estimate the health system costs of infection and to compare them across time-to-diagnosis categories.Methods:Administrative data from 2005–2016 were used to identify cases diagnosed with SSI up to 1 year following primary TKA. Uninfected controls were selected matched on age, sex and comorbidities. Costs and utilization were measured over the 2-year period following surgery using hospital and out-of-hospital data. Costs and utilization were compared for those diagnosed within 30, 90, 180, and 365 days. A subsample of cases and controls without comorbidities were also compared.Results:We identified 238 SSI cases over the study period. On average, SSI cases cost 8 times more than noninfected controls over the 2-year follow-up period (CaD$41,938 [US$29,965] vs CaD$5,158 [US$3,685]) for a net difference of CaD$36,780 (US$26,279). The case-to-control ratio for costs was lowest for those diagnosed within 30 days compared to those diagnosed later. When only patients without comorbidities were included, costs were >7 times higher.Conclusion:Our results suggest that considerable costs result from SSI following TKA and that those costs vary depending on the time of diagnosis. A 2-year follow-up period provided a more complete estimate of cost and utilization.
Limit theorems for additive functionals of continuous time random walks
Authors: Kondratiev Yuri , Mishura Yuliya , Shevchenko Georgiy 
Published: May 2020

AbstractFor a continuous-time random walk X = {Xt, t ⩾ 0} (in general non-Markov), we study the asymptotic behaviour, as t → ∞, of the normalized additive functional $c_t\int _0^{t} f(X_s)\,{\rm d}s$, t⩾ 0. Similarly to the Markov situation, assuming that the distribution of jumps of X belongs to the domain of attraction to α-stable law with α > 1, we establish the convergence to the local time at zero of an α-stable Lévy motion. We further study a situation where X is delayed by a random environment given by the Poisson shot-noise potential: $\Lambda (x,\gamma )= {\rm e}^{-\sum _{y\in \gamma } \phi (x-y)},$ where $\phi \colon \mathbb R\to [0,\infty )$ is a bounded function decaying sufficiently fast, and γ is a homogeneous Poisson point process, independent of X. We find that in this case the weak limit has both ‘quenched’ component depending on Λ, and a component, where Λ is ‘averaged’.
A deeper and distributed search for culture

Abstract
The target article does not address the neural mediation of complex social behavior. I review evidence that such mediation may be compatible with proposed Bayesian information-processing principles. Notably, however, such mediation occurs subcortically as well as cortically, concerns reward uncertainty and information uncertainty, and impacts culture via group-level payoff structures that define individualism and collectivism.
Digital life, a theory of minds, and mapping human and machine cultural universals
Authors: Clark Kevin B. 
Published: May 2020

AbstractEmerging cybertechnologies, such as social digibots, bend epistemological conventions of life and culture already complicated by human and animal relationships. Virtually-augmented niches of machines and organic life promise new free-energy-governed selection of intelligent digital life. These provocative eco-evolutionary contexts demand a theory of (natural and artificial) minds to characterize and validate the immersive social phenomena universally-shaping cultural affordances.
