Boundary states, overlaps, nesting and bootstrapping AdS/dCFT
Authors: Gombor Tamas , Bajnok Zoltan 
Published: October 2020

Abstract
Integrable boundary states can be built up from pair annihilation amplitudes called K-matrices. These amplitudes are related to mirror reflections and they both satisfy Yang Baxter equations, which can be twisted or untwisted. We relate these two notions to each other and show how they are fixed by the unbroken symmetries, which, together with the full symmetry, must form symmetric pairs. We show that the twisted nature of the K-matrix implies specific selection rules for the overlaps. If the Bethe roots of the same type are paired the overlap is called chiral, otherwise it is achiral and they correspond to untwisted and twisted K-matrices, respectively. We use these findings to develop a nesting procedure for K-matrices, which provides the factorizing overlaps for higher rank algebras automatically. We apply these methods for the calculation of the simplest asymptotic all-loop 1-point functions in AdS/dCFT. In doing so we classify the solutions of the YBE for the K-matrices with centrally extended $$ \mathfrak{su} $$

Abstract
Symbol alphabets of n-particle amplitudes in $$ \mathcal{N} $$
N
= 4 super-Yang-Mills theory are known to contain certain cluster variables of Gr(4, n) as well as certain algebraic functions of cluster variables. In this paper we suggest an algorithm for computing these symbol alphabets from plabic graphs by solving matrix equations of the form C ∙ Z = 0 to associate functions on Gr(m, n) to parameterizations of certain cells of Gr(k, n) indexed by plabic graphs. For m = 4 and n = 8 we show that this association precisely reproduces the 18 algebraic symbol letters of the two-loop NMHV eight-particle amplitude from four plabic graphs.

AbstractThe application of anticancer drugs during pregnancy is associated with placenta-related adverse pregnancy outcomes. Therefore, it is important to study placental toxicity of anticancer drugs. The aim of this study was to compare effects on viability and steroidogenesis in placental tissue explants and trophoblast cell lines. Third trimester placental tissue explants were exposed for 72 h (culture day 4–7) to a concentration range of doxorubicin, paclitaxel, cisplatin, carboplatin, crizotinib, gefitinib, imatinib, or sunitinib. JEG-3, undifferentiated BeWo, and syncytialised BeWo cells were exposed for 48 h to the same drugs and concentrations. After exposure, tissue and cell viability were assessed and progesterone and estrone levels were quantified in culture medium. Apart from paclitaxel, all compounds affected both cell and tissue viability at clinically relevant concentrations. Paclitaxel affected explant viability moderately, while it reduced cell viability by 50% or more in all cell lines, at 3–10 nM. Doxorubicin (1 µM) reduced viability in explants to 83 ± 7% of control values, whereas it fully inhibited viability in all cell types. Interference with steroid release in explants was difficult to study due to large variability in measurements, but syncytialised BeWo cells proved suitable for this purpose. We found that 1 µM sunitinib reduced progesterone release to 76 ± 6% of control values, without affecting cell viability. While we observed differences between the models for paclitaxel and doxorubicin, most anticancer drugs affected viability significantly in both placental explants and trophoblast cell lines. Taken together, the placenta should be recognized as a potential target organ for toxicity of anticancer drugs.

Published: October 2020

AbstractKyrgyz walnut-fruit forests harbour a unique walnut diversity, which has rarely been investigated concerning nut properties and the influence of environmental conditions on these. We evaluated the influence of soil properties and altitude on physical and some chemical walnut properties at three sampling sites differing in altitude by 200 m. Walnut samples were collected from 15 randomly chosen trees. Soil samples from two depths under each tree were analysed for plant available mineral nutrients and soil chemical properties. In contrast to our hypothesis, physical nut and chemical kernel quality parameters did not differ between sampling sites at different altitude and were not affected by soil properties. Only pH showed a relationship with manganese availability in soil and kernel content, and was related to amino acid content of kernels. Tree and site-specific variability overrides abiotic influence caused by different altitude or soil properties and reflect the high genetic variability in these forests.

AbstractBackgroundCardiac magnetic resonance myocardial feature tracking (CMR-FT)-derived global strain assessments provide incremental prognostic information in patients following acute myocardial infarction (AMI). Functional analyses of the remote myocardium (RM) are scarce and whether they provide an additional prognostic value in these patients is unknown.Methods1034 patients following acute myocardial infarction were included. CMR imaging and strain analyses as well as infarct size quantification were performed after reperfusion by primary percutaneous coronary intervention. The occurrence of major adverse cardiac events (MACE) within 12 months after the index event was defined as primary clinical endpoint.ResultsPatients with MACE had significantly lower RM circumferential strain (CS) compared to those without MACE. A cutoff value for RM CS of − 25.8% best identified high-risk patients (p < 0.001 on log-rank testing) and impaired RM CS was a strong predictor of MACE (HR 1.05, 95% CI 1.07–1.14,p = 0.003). RM CS provided further risk stratification among patients considered at risk according to established CMR parameters for (1) patients with reduced left ventricular ejection fraction (LVEF) ≤ 35% (p = 0.038 on log-rank testing), (2) patients with reduced global circumferential strain (GCS) > −  18.3% (p = 0.015 on log-rank testing), and (3) patients with large microvascular obstruction ≥ 1.46% (p = 0.002 on log-rank testing).ConclusionCMR-FT-derived RM CS is a useful parameter to characterize the response of the remote myocardium and allows improved stratification following AMI beyond commonly used parameters, especially of high-risk patients.Trial registrationClinicalTrials.gov, NCT00712101 and NCT01612312Graphic abstractDefining remote segments (R) in the presence of infarct areas (I) for the analysis of remote circumferential strain (CS). Remote CS was significantly lower in patients who suffered major adverse cardiac events (MACE) and a cutoff value for remote CS of − 25.8% best identified high-risk patients. In addition, impaired remote CS ≥ − 25.8 % (Remote −) and preserved remote CS < − 25.8 % (Remote +) enabled further risk stratification when added to established parameters like left ventricular ejection fraction (LVEF), global circumferential strain (GCS) or microvascular obstruction (MVO).

AbstractPurposeInfertility is a global problem, but only a minority of couples access assisted reproductive technologies due to financial and sociocultural barriers. Complementary and alternative medicine are seen as another option. We aimed to determine the impact of complementary and alternative medicine on conception, miscarriage and live birth rates in couples not receiving assisted reproductive technology treatments.MethodsThe electronic databases EMBASE, PubMed, Web of Science and the Allied and Complementary Medicine Database were systematically searched before March 24th 2020. Reference lists of eligible studies were searched for relevant studies. Eligible studies included trials and observational studies that assessed a complementary or alternative medicine and conception, miscarriage or live births in men or women not undergoing fertility treatment. Data were extracted by two independent reviewers using a pre-designed data collection form. The study protocol was published in the PROSPERO database (CRD42018086980).ResultsTwenty randomized controlled trials were identified, including 2748 individuals. Most studies did not demonstrate any effect of a complementary or alternative medicine on pregnancy, live birth or miscarriage rates. Limited evidence was found for a positive effect of herbal therapies taken by women on conception rates. There was substantial diversity in quality across the studies.ConclusionThere is limited evidence of the effectiveness of complementary and alternative medicine on improving the chances of conception and live births, or increasing miscarriage risk. Owing to the generally sub-optimal quality and heterogeneous nature of the evidence, rigorous studies are needed to determine the impact of complementary and alternative medicine on fertility.
Introduction to the symposium: seed as a commons—exploring innovative concepts and practices of governing seed and varieties
Authors: Sievers-Glotzbach Stefanie , Christinck Anja 
Published: October 2020

AbstractThis Symposium explores how the theory of commons can be used to study, conceptualize and transform governance models for seed and plant varieties to counter ongoing trends towards agrobiodiversity loss and concentration of economic and political power in farming and food systems. Contributions to the Symposium present case studies from a range of geographical and socio-cultural contexts from the Global North and South. They show how seed and varieties relate to various known commons categories, including natural resource commons, knowledge and cultural commons, and global commons. Elements of these categories need to be integrated to gain a deeper understanding of Seed Commons, including the specific challenges that arise from the fact that seed, although a biological asset, is at least partly shaped by human selection driven by values, knowledge and needs of users. Collective responsibility, sharing of knowledge and seed, protection from private enclosure, and distributed, polycentric governance are key features of Seed Commons. The notion of ‘commoning’ focuses on the social practices and processes that create and sustain commons. Conceptualizing Seed Commons in their complexity offers initial starting points for policies and legal frameworks conducive to releasing the transformative power of Seed Commons for advancing sustainable farming and food systems.
Swedish Adolescent Female Offenders with Limited Delinquency: Exploring Family-Related Narratives from a Developmental Perspective
Authors: Ginner Hau Hanna , Azad Azade 
Published: October 2020

AbstractFamily factors are central both for adolescent development in general and for the development of delinquency. For female delinquency they appear to be particularly important. The aim of this study was to explore family-related statements in adolescent females’ delinquency narratives from a developmental perspective. Interviews with nine female adolescent offenders were analysed using consensual qualitative research (CQR). The main findings consisted of five themes concerning the family in relation to the participants’ delinquency. In the delinquency narratives, families were described as being involved in the entire process of delinquency. Urges both for proximity and distance in family relations were expressed in the narratives. Delinquency was also found to be related to transactions between participants and their families. Our findings indicate that the developmental perspective on family factors for females with limited delinquency is a meaningful way to further investigate this group of offenders. Furthermore, this perspective could in the long-term also potentially contribute to the design of adequate community-based measures for this yet under-researched group of young offenders.
Comparativism and the Measurement of Partial Belief
Authors: Elliott Edward 
Published: October 2020

AbstractAccording to comparativism, degrees of belief are reducible to a system of purely ordinal comparisons of relative confidence. (For example, being more confident that P than that Q, or being equally confident that P and that Q.) In this paper, I raise several general challenges for comparativism, relating to (1) its capacity to illuminate apparently meaningful claims regarding intervals and ratios of strengths of belief, (2) its capacity to draw enough intuitively meaningful and theoretically relevant distinctions between doxastic states, and (3) its capacity to handle common instances of irrationality.
Corona pan(dem)ic: gateway to global surveillance
Authors: Surber Regina Sibylle 
Published: October 2020

AbstractThe essay reviews the digital emergency measures many governments have adopted in an attempt to curb Covid-19. It argues that those ‘virologically legitimized’ measures may infringe the human right to privacy and mark the transition into a world of global surveillance. At this possible turning point in human history, panic and latent fear seem to fog much needed farsightedness. Leaving the current state of emotional paralysis and restarting to critically assess the digital pandemic management can serve as an emergency break against drifting into a new era of digital monitoring.
Liberalism Versus Communitarianism in Cultural Heritage Law
Authors: Zeidler Kamil , Łągiewska Magdalena 
Published: October 2020

AbstractThe aim of this study is to investigate the important role of liberal-communitarian debate in cultural heritage law and politics. Derek Gillman in the book titled “The Idea of Cultural Heritage” stressed that “During recent decades, two parallel debates have occurred with respect to public policy and heritage”, and mentioned above is the second one, which “takes place between political philosophers, especially liberal and communitarian thinkers of various shades.” The following study brings attention to the external perspective. That is, these philosophical concepts which appeared beyond legal sciences, but they have the impact on both law and almost all aspects of social life. Liberalism and communitarianism, despite their differences, are particularly useful lens through which to consider law and its functions within contemporary society. Therefore, this begs the question as to what is their approach to the cultural heritage law and practice. While much has been written about liberalism and communitarianism, their impact on cultural heritage still remains shrouded in mystery. We do accept and stress that cultural heritage law is nowadays recognised as the multilevel legal instruments for safeguarding, protection, preservation and maintenance of cultural heritage, cultural property, or even cultural rights. It is not only “multilevel”, but also “multivalued”, and for that reason many theoretical and practical problems are noticed. Liberalism versus communitarianism is one of the most significant debate. As a result, the main aim of this article is to outline the influence of liberalism and communitarianism on cultural heritage law.
Inactivation of Escherichia coli enhanced by anaerobic microbial iron reduction
Authors: Kim Lavane , Yan Tao , Pham Van Toan 
Published: October 2020

AbstractMicrobial iron reduction (MIR) is an important and ubiquitous natural process in the biogeochemical cycling of iron and carbon in anaerobic sedimentary and subsurface environments. The objectives of this study were (1) to determine if the MIR process can enhance the inactivation of Escherichia coli cells under anaerobic conditions and (2) to identify potential inactivation mechanisms. Laboratory microcosm experiments showed that the presence of MIR activity significantly enhanced E. coli inactivation, and the inactivation rate under the MIR condition was significantly larger than those under other anaerobic redox conditions. Under anoxic condition, higher Fe2+concentrations exhibited a linear function to larger E. coli inactivation rates, indicating that the production of Fe2+by MIR was one of the important roles in E. coli inactivation. When E. coli cells were amended as the sole electron source to the MIR process, increased Fe2+ production was observed, which corresponded to decreasing TOC concentration. Together, the results suggest that MIR enhanced E. coli inactivation through the production of Fe2+ as metabolic waste, and the inactivation benefited the MIR process as the inactivated cells were used as an electron source, which represents a potential new mechanism for bacterial inter-species competition. This knowledge could further improve our understanding of the fate of fecal bacteria in natural environments where the MIR process is prevalent, and may also be explored for enhanced removal of bacterial pathogens in engineering processes.
Sociodrama as a “potential stage” for creating participative and transformative research on social work with families living in vulnerable situations
Authors: Ius Marco 
Published: October 2020

AbstractThis article of the Zeitschrift für Psychodrama und Soziometrie aims to explore how Morenian sociodrama and its techniques represent valuable tools for participative research with social professionals and teachers working with children and their families in vulnerable situations. After introducing the Canon of Creativity by Moreno and its connection to art-based research, sociodrama is theoretically introduced and proposed as a research tool. This is followed by a description of an experience of participative research with a group of roughly 40 professionals within the national Italian programme P.I.P.P.I. The process of the session is described and discussed, in order to demonstrate how sociodrama can be an interesting tool for social research. The conclusion provides connections between practice and research, proposing the involvement of families in future activities, and highlighting possible future theoretical explorations in order to examine the topic in greater depth.

AbstractCinnamomum camphora(L.) J. Presl. (Laurales: Lauraceae) is widely cultivated as an important landscape tree species in many urban areas in South China, especially in Shanghai City.Pagiophloeus tsushimanusMorimoto has become a destructive insect pest ofC.camphoraplantations in Shanghai, but the biological and ecological traits of this pest remain largely unknown. In this study, we investigated the damage and life history and determined the larval instar ofP.tsushimanus. The results indicated thatP.tsushimanusis a monophagous weevil pest, andC.camphorais the unique host tree species.C.camphoraplantations in all administrative districts of Shanghai have been seriously damaged byP.tsushimanus. Adults often aggregate for feeding on the tender bark of twigs and occasionally on newly emerged buds. After experiencing damage, the twigs shrink and crack and the buds will shrink. Adults tend to repeatedly mate and oviposit, and all females lay single eggs at a time. Eggs will be covered with a mixture of secretions and wood chips by female adults. Larvae (1st–2nd instar) feed on the phloem, while 3rd–5th instar can bore into the phloem and the cambium. Massive tunnels, including three shapes (inverted “L”, inverted “T”, and inverted “Z”), were observed in the trunk of each tree, and resulted in swelling of the outer bark.P.tsushimanushas one life cycle per year in Shanghai. Both adults and larvae (3rd–5th instar) overwinter from early November to early April. Adults overwinter in grooves on the underside of branches or at branch nodes, and larvae overwinter in tunnels. Five larval instars ofP.tsushimanuswere determined according to Dyar's and Crosby's rules. The biological traits and life history ofP.tsushimanushave been identified and can provide guidance in terms of pest control and plantation management.
Electrochemical, spectroscopic and theoretical studies for acid corrosion of zinc using glycogen
Authors: Pais Mikitha , Rao Padmalatha 
Published: October 2020

AbstractThe objective of the work is to introduce and establish anticorrosion capabilities of a novel biopolymer glycogen (GLY) against sulfamic acid (NH2SO3H) induced corrosion of zinc. The corrosion and inhibition studies were done by electrochemical techniques such as potentiodynamic polarization (PDP) measurements and electrochemical impedance spectroscopy technique (EIS). Conditions were optimized to get maximum inhibition efficiency by varying the concentration of the inhibitor in the temperature range of 303–323 K. Activation and thermodynamic parameters were evaluated and discussed in detail. Suitable adsorption isotherm was proposed to fit the experimental results. Scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and atomic force microscopy (AFM) studies were performed before and after the addition of inhibitor. Adsorption of inhibitor was further confirmed by UV–Visible spectroscopy. Quantum chemical calculations were done to establish the correlation between the structure of the inhibitor and its inhibition efficiency. Energy of HOMO, LUMO, energy gap ∆E, dipole moment (µ) Mullikan charges were calculated. Different theoretical factor descriptors like the hardness (η), and softness (σ) electronegativity (χ), global electrophilicity (ω), nucleophilicity (ε) and fraction of electron transferred (ΔN) were calculated. Inhibition efficiency of glycogen increased with increase in its concentration and with temperature. Maximum efficiency of 72% could be achieved for the addition of 0.05 g L−1of GLY at 323 K. Results were fitted into Langmuir adsorption iostherm. The surface of the metal turned visibly smoother in the presence of GLY. In addition the EDX studies showed increase in carbon content which re-affirmed the adsorption of GLY on the metal surface. The density functional theory (DFT) based theoretical studies supported the experimental observations.
