, maximized with respect to semidefinite constraints on D and E. Applied to the problem of approximate error correction in quantum information theory, this gives hierarchies of efficiently computable outer bounds on the success probability of approximate quantum error correction codes in any dimension. The first level of our hierarchies corresponds to a previously studied relaxation (Leung and Matthews in IEEE Trans Inf Theory 61(8):4486, 2015) and positive partial transpose constraints can be added to give a sufficient criterion for the exact convergence at a given level of the hierarchy. To quantify the worst case convergence speed of our sum-of-squares hierarchies, we derive novel quantum de Finetti theorems that allow imposing linear constraints on the approximating state. In particular, we give finite de Finetti theorems for quantum channels, quantifying closeness to the convex hull of product channels as well as closeness to local operations and classical forward communication assisted channels. As a special case this constitutes a finite version of Fuchs-Schack-Scudo’s asymptotic de Finetti theorem for quantum channels. Finally, our proof methods answer a question of Brandão and Harrow (Proceedings of the forty-fourth annual ACM symposium on theory of computing, STOC’12, p 307, 2012) by improving the approximation factor of de Finetti theorems with no symmetry from $$O(d^{k/2})$$

Abstract
Background
Management of cryptoglandular fistula-in-ano (FIA) can be challenging. Despite Dutch and international guidelines determining optimal therapy is still quite difficult. The aim of this study was to report current practices in the management of cryptoglandular FIA among gastrointestinal surgeons in the Netherlands.

Methods
Dutch surgeons and residents who are treating FIA regularly were sent a survey invitation by email. The survey was available online from September 19 to December 1 2019. The questionnaire consisted of 28 questions concerning diagnostic and surgical techniques in the treatment of intersphincteric and transsphincteric FIA.

Results
In total, 147 (43%) surgeons responded and completed the survey. Magnetic resonance imaging was the preferred diagnostic imaging modality (97%) followed by the endo-anal ultrasound (12%). In case of a high FIA, 86% used a non-cutting seton. Most respondents removed a seton between 6 weeks and 3 months (n = 84, 58%). Fistulotomy was the procedure of preference in low transsphincteric (86%) and low intersphincteric FIA (92%). Mucosal advancement flap (MAF) and ligation of intersphincteric fistula tract (LIFT), with 78% and 46%, respectively, were the procedures that were applied most often in high transsphincteric FIA. In high intersphincteric FIA 67% performed a MAF and 33% a fistulotomy. Thirty-three percent of all respondents stated that they habitually closed the internal fistula opening, half of them used a Z-plasty. For debridement of the fistula tract the preferred method was curettage (78%).

Conclusions
Dutch gastrointestinal surgeons use various techniques in the management of FIA. Novel promising techniques should be investigated adequately in sufficient large trials to increase consensus. A core outcome measurement and a prospective international database would help in comparing results. Until then, treatment should be adjusted to the individual patient, governed by fistula characteristics and patient choice.
Non-invasive diagnostic PCRs for rapid detection of golden jackal, red fox, and gray wolf/domestic dog and application to validate golden jackal presence in Styria, Austria

Published: April 2021

AbstractHuman-predator conflicts are frequently caused by livestock and/or game depredation. The golden jackal’s (Canis aureus) range expansion in Europe, as well as the recent re-expansion of several gray wolf (Canis lupus) populations, might increase risk of such conflicts. In Austria, golden jackal presence has been increasing since the 1990s including reports of wildlife and livestock kills, frequently occurring in the provinces Styria and Burgenland. We developed a rapid, two-step genetic screening protocol to (1) detect canid mtDNA from non-invasively collected samples like swabs from kills using diagnostic PCRs, and (2) assign this DNA to red fox (Vulpes vulpes), golden jackal, or gray wolf/dog. To monitor golden jackal presence in the region, a total of 167 signs of presence were collected over a period of 30 months throughout the Styrian province. Among these, 14 non-invasive genetic samples (13 swabs from kill sites and one scat) were screened with the developed protocol. Four of these samples revealed golden jackal mtDNA and six samples red fox mtDNA. The developed genetic screening protocol represents a quick and inexpensive method to assess canid presence, e.g., at kill sites, and therefore possesses high value for the conservation and wildlife management community.

Published: April 2021

AbstractTraditional robot programming is often not feasible in small-batch production, as it is time-consuming, inefficient, and expensive. To shorten the time necessary to deploy robot tasks, we need appropriate tools to enable efficient reuse of existing robot control policies. Incremental Learning from Demonstration (iLfD) and reversible Dynamic Movement Primitives (DMP) provide a framework for efficient policy demonstration and adaptation. In this paper, we extend our previously proposed framework with improvements that provide better performance and lower the algorithm’s computational burden. Further, we analyse the learning stability and evaluate the proposed framework with a comprehensive user study. The proposed methods have been evaluated on two popular collaborative robots, Franka Emika Panda and Universal Robot UR10.

AbstractMetacognitive monitoring is a significant predictor of academic achievement and is assumed to be related to language competencies. Hence, it may explain academic performance differences between native and non-native speaking students. We compared metacognitive monitoring (in terms of resolution) between native and non-native speaking fourth graders (~ 10 year olds) in two studies. In Study 1, we matched 30 native and 30 non-native speakers and assessed their monitoring in the context of a paired-associates task, including a recognition test and confidence judgements. Study 1 revealed that recognition and monitoring did not differ between native and non-native speaking children. In Study 2, we matched 36 native and 36 non-native speakers and assessed their monitoring with the same paired-associates task. Additionally, we included a text comprehension task with open-ended questions and confidence judgments. We replicated the findings of Study 1, suggesting that recognition and monitoring do not necessarily differ between native and non-native speakers. However, native speaking students answered more open-ended questions correctly than non-native speaking students did. Nevertheless, the two groups did not differ in monitoring their answers to open-ended questions. Our results indicate that native and non-native speaking children may monitor their metacognitive resolution equally, independent of task performance and characteristics. In conclusion, metacognitive monitoring deficits may not be the primary source of the academic performance differences between native and non-native speaking students.

Published: April 2021

AbstractDiabetes, one of the top 10 causes of death worldwide, is associated with the interaction between lifestyle, psychosocial, medical conditions, demographic, and genetic risk factors. Predicting type 2 diabetes is important for providing prognosis or diagnosis support to allied health professionals, and aiding in the development of an efficient and effective prevention plan. Several works proposed machine-learning algorithms to predict type 2 diabetes. However, each work uses different datasets and evaluation metrics for algorithms’ evaluation, making it difficult to compare among them. In this paper, we provide a taxonomy of diabetes risk factors and evaluate 35 different machine learning algorithms (with and without features selection) for diabetes type 2 prediction using a unified setup, to achieve an objective comparison. We use 3 real-life diabetes datasets and 9 feature selection algorithms for the evaluation. We compare the accuracy, F-measure, and execution time for model building and validation of the algorithms under study on diabetic and non-diabetic individuals. The performance analysis of the models is elaborated in the article.
Fibroblast Growth Factor Signalling in the Diseased Nervous System
Authors: Klimaschewski Lars , Claus Peter 
Published: April 2021

AbstractFibroblast growth factors (FGFs) act as key signalling molecules in brain development, maintenance, and repair. They influence the intricate relationship between myelinating cells and axons as well as the association of astrocytic and microglial processes with neuronal perikarya and synapses. Advances in molecular genetics and imaging techniques have allowed novel insights into FGF signalling in recent years. Conditional mouse mutants have revealed the functional significance of neuronal and glial FGF receptors, not only in tissue protection, axon regeneration, and glial proliferation but also in instant behavioural changes. This review provides a summary of recent findings regarding the role of FGFs and their receptors in the nervous system and in the pathogenesis of major neurological and psychiatric disorders.
Fictionalism of Anticipation
Authors: Vidunas Raimundas 
Published: April 2021

AbstractA promising recent approach for understanding complex phenomena is recognition of anticipatory behavior of living organisms and social organizations. The anticipatory, predictive action permits learning, novelty seeking, rich experiential existence. I argue that the established frameworks of anticipation, adaptation or learning imply overly passive roles of anticipatory agents, and that afictionaliststandpoint reflects the core of anticipatory behavior better than representational or future references. Cognizing beings enact not just their models of the world, but own make-believeexistential agendasas well. Anticipators embody plausible scripts of living, and effectively assume neo-Kantian or pragmatist perspectives of cognition and action. It is instructive to see that anticipatory behavior is not without mundane or loathsome deficiencies. Appreciation of ferally fictionalist anticipation suggests an equivalence of semiosis and anticipation.
Thrombose und COVID-19
Authors: Tzaneva Stanislava 
Published: April 2021

ZusammenfassungDie Prävalenz der venösen thromboembolischen (VTE) Ereignisse ist bei Coronavirus diesease 2019 (COVID-19) -Patienten hoch, insbesondere bei schwer Erkrankten. Patienten mit schwerer COVID-19 und VTE haben eine signifikant höhere Mortalität im Vergleich zu Patienten ohne VTE. Die Manifestation einer schweren Infektion mit Severe acute respiratory syndrome coronavirus-2 (SARS-CoV‑2) entspricht einem systemischen proinflammatorischen und prokoagulatorischen Phänotyp, der mit vaskulären Thrombosen nicht nur in den Venen, sondern auch in den Arterien, Kapillaren sowie mit einer Inflammation der Gefäße assoziiert ist. Ein erhöhter D‑Dimer-Spiegel kann als Indikator für VTE bei Patienten mit COVID-19 verwendet werden. Die meisten medizinischen Gesellschaften empfehlen eine VTE-Prophylaxe vorzugsweise mit niedermolekularen Heparinen (LMWH) bei allen stationären Patienten. Weitere Daten von randomisierten kontrollierten Studien (RCTs) über die optimale Antikoagulation und antithrombotische Therapie werden in der nahen Zukunft erwartet.
Rare Occurrence of Mirabilite in the Thirteenth-Century Historic Salt Mine in Bochnia (Poland): Characterisation, Preservation, and Geotourism

Published: April 2021

AbstractThe small stalactites found on the ceiling at level I near the Sutoris shaft in the thirteenth-century historic salt mine in Bochnia, Poland, are mainly composed of mirabilite (Na2SO4·10H2O) followed by blödite (Na2Mg(SO4)2·4H2O). The unique presence of these two minerals in only one location in this old underground mine is attributed to contemporary precipitation from percolating solutions. This can be caused by a combination of at least two factors: a specific and stable microclimate (characterised by a low temperature, high humidity, and relatively strong air circulation which accelerates the processes of evaporation and crystallisation) and the specific chemical composition of the leaking solution (contains a low carbonate and high sulphate content, and characterised by acidic pH (4.8) and intermediate-mineralisation (174,308 mg/L)). The microclimate specified above can be linked to the long distance from the ventilation shaft that pumps the air from the surface to the mine, while the composition of the leaking solution as well as the hydrochemical modelling results obtained with PHREEQC can be directly related to the top anhydrite layer and the overlying secondary cap consisting mainly of claystone, anhydrite, and gypsum. In this study, the challenges underlying the preservation of mirabilite in the underground environment of the salt mine are discussed, in terms of both nature and mining law. Based on the results of detailed geological, mineralogical, and chemical research, appropriate solutions that can be practically applied for the management, preservation, and protection of the mirabilite efflorescence are proposed. The presence of this intriguing mineral, with appropriate protection, can be another geological attraction for tourists visiting this thirteenth-century UNESCO-recognised salt mine.

Abstract(Ba1−xSrx)(MnyTi1−y)O3(BSMT) ceramics withx= 35, 40 mol% andy= 0, 0.1, 0.2, 0.3, 0.4, 0.5 mol% were prepared using a conventional solid-state reaction approach. The dielectric and ferroelectric properties were characterized using impedance analysis and polarization-electric field (P–E) hysteresis loop measurements, respectively. The adiabatic temperature drop was directly measured using a thermocouple when the applied electric field was removed. The results indicate that high permittivity and low dielectric losses were obtained by doping 0.1–0.4 mol% of manganese ions in (BaSr)TiO3(BST) specimens. A maximum electrocaloric effect (ECE) of 2.75 K in temperature change with electrocaloric strength of 0.55 K·(MV/m)−1was directly obtained at ∼21 °C and 50 kV/cm in Ba0.6Sr0.4Mn0.001Ti0.999O3sample, offering a promising ECE material for practical refrigeration devices working at room temperature.
Microstructure and mechanical properties of Zr3Al3C5-based ceramics synthesized by Al-Si melt infiltration

Published: April 2021

AbstractIn this work, bulk Zr3Al3C5-based ceramics were synthesized by the infiltration of Al-Si melt into zirconium carbide (ZrC) perform. The phase composition, microstructure, and mechanical properties of as-fabricated ceramics were studied. The results demonstrate that Si is more effective to reduce the twin boundary energy of ZrC than Al, and thus promotes the decrease of formation temperature of Zr3Al3C5. With the infiltration temperatures increasing from 1200 to 1500 °C, the Zr3Al3C5 content increases from 10 to 49 vol%, which is contributed to the increase of flexural strength from 62±9 to 222±10 MPa, and fracture toughness (KIC) from 2.8±0.2 to 4.1±0.3 MPa·m1/2. The decrease of mechanical properties for the samples fabricated at 1600 °C is ascribed to the abnormal growth of Zr3Al3C5 grains.
Darwin’s perception of nature and the question of disenchantment: a semantic analysis across the six editions of On the Origin of Species
Authors: Jiménez-Pazos Bárbara 
Published: April 2021

AbstractThis body of work is motivated by an apparent contradiction between, on the one hand, Darwin’s testimony in his autobiographical text about a supposed perceptual colour blindness before the aesthetic magnificence of natural landscapes, and, on the other hand, the last paragraph ofOn the Origin of Species, where he claims to perceive the forms of nature as beautiful and wonderful. My aim is to delve into the essence of the Darwinian perception of beauty in the context of the Weberian concept of “disenchantment of the world”, assumed as a possible conceptual axis that enables the unravelling of the core of this contrast of perceptions. In acknowledging the theory of evolution as one of the most prominent scientific theories likely to have contributed to disenchantment, a number of questions arise: Is disenchantment compatible with aesthetic experience and sensibility before natural beauty? Was it Darwin’s disenchanted conception of the world that led him to believe he was colour blind? To answer these questions, a computer-assisted semantic analysis of lexical frequency and variability, most especially focused on aesthetic-emotional and religious or spiritual adverbs and adjectives, has been undertaken across the six editions ofThe Origin. The semantic analysis demonstrates that, although disenchanted, Darwin’s descriptions of, mainly, the adaptational excellence of living beings, reflect an aesthetically enriched perception of nature. It is concluded that Darwin’s perceptual colour blindness, then, might be based on a confusion rooted in the equation of equality between aesthetic sensibility in nature and the perception of its beauty as part of thevestigia Dei.
Operations management of smart logistics: A literature review and future research
Authors: Feng Bo , Ye Qiwen 
Published: April 2021

AbstractThe global collaboration and integration of online and offline channels have brought new challenges to the logistics industry. Thus, smart logistics has become a promising solution for handling the increasing complexity and volume of logistics operations. Technologies, such as the Internet of Things, information communication technology, and artificial intelligence, enable more efficient functions into logistics operations. However, they also change the narrative of logistics management. Scholars in the areas of engineering, logistics, transportation, and management are attracted by this revolution. Operations management research on smart logistics mainly concerns the application of underlying technologies, business logic, operation framework, related management system, and optimization problems under specific scenarios. To explore these studies, the related literature has been systematically reviewed in this work. On the basis of the research gaps and the needs of industrial practices, future research directions in this field are also proposed.
Self‐management interventions for adults with stroke: A scoping review
Authors: Ruksakulpiwat Suebsarn , Zhou Wendie 
Published: April 2021

AbstractBackgroundStroke is a principal cause of mortality and disability globally. Numerous studies have contributed to the knowledge base regarding self‐management interventions among chronic disease patients, but there are few such studies for patients with stroke. Therefore, it is necessary to analyze self‐management interventions among stroke patients. This scoping review aimed to systematically identify and describe randomized controlled trials (RCTs) of self‐management interventions for adults with stroke.MethodsA review team carried out a scoping review on stroke and self‐management interventions based on the methodology of Arksey and O'Malley, following the Preferred Reporting Items for Systematic reviews and Meta‐Analyses extension for Scoping Reviews (PRISMA‐ScR). PubMed, Embase, Web of Science, CINAHL Plus Full Text, Medline Plus Full Text, and Cochrane Central Register of Controlled Trials were searched from inception to July 2020.ResultsFifty‐four RCTs were included. The most popular study design is comparing a self‐management intervention to usual care or waitlist control condition. Physical activity is the most common intervention topic, and interventions were mainly delivered face to face. The majority of interventions were located in inpatient and multiple settings. Interventions were conducted by various providers, with nurses the most common provider group. Symptom management was the most frequently reported outcome domain that improved.ConclusionsSelf‐management interventions benefit the symptom management of stroke patients a lot. The reasonable time for intervention is at least 6–12 months. Multifarious intervention topics, delivery formats, and providers are adopted mostly to meet the multiple needs of this population. Physical activity was the most popular topic currently. Studies comparing the effect of different types of self‐management interventions are required in the future.
