Quantum Chern–Simons Theories on Cylinders: BV-BFV Partition Functions
Authors: Cattaneo Alberto S. , Mnev Pavel , Wernli Konstantin 
Published: December 2022

AbstractWe compute partition functions of Chern–Simons type theories for cylindrical spacetimes$$I \times \Sigma $$I×Σ, withIan interval and$$\dim \Sigma = 4l+2$$dimΣ=4l+2, in the BV-BFV formalism (a refinement of the Batalin–Vilkovisky formalism adapted to manifolds with boundary and cutting–gluing). The case$$\dim \Sigma = 0$$dimΣ=0is considered as a toy example. We show that one can identify—for certain choices of residual fields—the “physical part” (restriction to degree zero fields) of the BV-BFV effective action with the Hamilton–Jacobi action computed in the companion paper (Cattaneo et al., Constrained systems, generalized Hamilton–Jacobi actions, and quantization,arXiv:2012.13270), without any quantum corrections. This Hamilton–Jacobi action is the action functional of a conformal field theory on$$\Sigma $$Σ. For$$\dim \Sigma = 2$$dimΣ=2, this implies a version of the CS-WZW correspondence. For$$\dim \Sigma = 6$$dimΣ=6, using a particular polarization on one end of the cylinder, the Chern–Simons partition function is related to Kodaira–Spencer gravity (a.k.a. BCOV theory); this provides a BV-BFV quantum perspective on the semiclassical result by Gerasimov and Shatashvili.

Supersymmetric Black Holes with a Single Axial Symmetry in Five Dimensions
Authors: Katona David , Lucietti James 
Published: December 2022

AbstractWe present a classification of asymptotically flat, supersymmetric black hole and soliton solutions of five-dimensional minimal supergravity that admit a single axial symmetry which ‘commutes’ with the supersymmetry. This includes the first examples of five-dimensional black hole solutions with exactly one axial Killing field that are smooth on and outside the horizon. The solutions have similar properties to the previously studied class with biaxial symmetry, in particular, they have a Gibbons–Hawking base and the harmonic functions must be of multi-centred type with the centres corresponding to the connected components of the horizon or fixed points of the axial symmetry. We find a large moduli space of black hole and soliton spacetimes with non-contractible 2-cycles and the horizon topologies are $$S^3$$

Gluon Scattering on Self-Dual Radiative Gauge Fields
Authors: Adamo Tim , Mason Lionel , Sharma Atul 
Published: December 2022

AbstractWe present all-multiplicity formulae, derived from first principles in the MHV sector and motivated by twistor string theory for general helicities, for the tree-level S-matrix of gluon scattering on self-dual radiative backgrounds. These backgrounds are chiral, asymptotically flat gauge fields characterised by their free radiative data, and their underlying integrability is captured by twistor theory. Tree-level gluon scattering scattering amplitudes are expressed as integrals over the moduli space of holomorphic maps from the Riemann sphere to twistor space, with the degree of the map related to the helicity configuration of the external gluons. In the MHV sector, our formula is derived from the Yang–Mills action; for general helicities the formulae are obtained using a background-coupled twistor string theory and pass several consistency tests. Unlike amplitudes on a trivial vacuum, there are residual integrals due to the functional freedom in the self-dual background, but for scattering of momentum eigenstates we are able to do many of these explicitly and even more is possible in the special case of plane wave backgrounds. In general, the number of these integrals is always less than expected from standard perturbation theory, but matches the number associated with space-time MHV rules in a self-dual background field, which we develop for self-dual plane waves.
‘The Good, the Bad and the Ugly’ of terminology in Cross Domain Fusion
Authors: Gross Felix , Hundsdörfer Marie , Jung Reiner , Karstens Svenja , Wagner-Ahlfs Christian 
Published: December 2022

AbstractThis article is a contribution to the Informatik Spektrum special issue „Cross-Domain Fusion“ – Heft 2. Terminologies are paramount to establish robust communication within interdisciplinary working groups inside and outside academia. To find the “common language” is hence essential and sometimes a long way to go. Within the idea of Cross Domain Fusion, we want to tackle this issue from the very beginning. Therefore, we set up a database based on the open source MediaWiki content management system. In this dictionary, a dedicated consortium from different disciplines evaluates terminologies used in Cross Domain Fusion and provides them within the Dialogue:Wiki. The aim is to provide accessible insight into commonalities and differences between different domain-specific terminologies to foster cross domain exchange.

AbstractThe application of next-generation sequencing (NGS) to clinical practice is still hampered by the ability to interpret the clinical relevance of novel variants and the difficulty of evaluating their effect in specific tissues. Here, we applied integrated genomic approaches for interrogating blood samples of two unrelated individuals with neurodevelopmental disorders and identified a novel neuro-pathogenic role for the Mitogen-Activated Protein Kinase 4 gene (MAP4K4). In particular, we identified two novel frameshift variants in coding exons expressed in the blood and neuronal isoforms. Both variants were predicted to generate non-sense-mediated decay. By transcriptome analysis, we simultaneously demonstrated the deleterious effect of the identified variants on the splicing activity and stability of MAP4K4 mRNA. Therefore, we propose MAP4K4 as a novel causative gene for non-syndromic and syndromic neurodevelopmental disorders. Altogether, we prove the efficacy of an integrated approach of exome and transcriptome sequencing in the resolution of undiagnosed cases by leveraging the analysis of variants in genes expressed in peripheral blood.
Quantum Meets Fine-Grained Complexity: Sublinear Time Quantum Algorithms for String Problems
Authors: Le Gall François , Seddighin Saeed 
Published: December 2022

AbstractLongest common substring (), longest palindrome substring (), and Ulam distance () are three fundamental string problems that can be classically solved in near linear time. In this work, we present sublinear time quantum algorithms for these problems along with quantum lower bounds. Our results shed light on a very surprising fact: Although the classic solutions for and are almost identical (via suffix trees), their quantum computational complexities are different. While we give an exact$${{\tilde{O}}}(\sqrt{n})$$O~(n)time algorithm for , we prove that needs at least time$$\tilde{\Omega }(n^{2/3})$$Ω~(n2/3)even for 0/1 strings.

Shock transmissions and business linkages among US sectors
Authors: Nguyen Linh Xuan Diep , Chevapatrakul Thanaset , Mateut Simona 
Published: December 2022

AbstractThis paper examines the shock spillovers between US sectors and their dependence on the intersectoral business linkages. Our forecast error variance decompositions reveal significant shock transmissions among trading sectors, especially in turbulent periods such as the financial crisis and the COVID-19 pandemic. The dymamics of shock spillovers reflect the impacts of the pandemic on economic sectors. Shock spillovers are shown to be influenced by the strength of the intersectoral trading relationships. Shocks to a sector’s important supplier have a strong impact on the forecast error variance of the sector’s stock return. The total directional spillovers from/ to a sector are linked with the number of close commercial linkages between that sector and other sectors.
Transcriptomic analysis reveals the regulation of early ear-length development in maize

Published: December 2022

AbstractEar length is an important component of maize grain yield. However, the ear length is a complex quantitative trait, and the underlying molecular mechanisms remain poorly understood. Here, the chromosome segment substitution line (CSSL) 1283 displayed a longer ear length compared with the recipient parent Xu178. An RNA sequencing analysis of Xu178 and CSSL1283 ears during three undifferentiated ear developmental stages identified 1,991 differentially expressed genes (DEGs). A gene ontology analysis of the DEGs showed that genes related to transcription factors and response to abiotic stimulus were significantly enriched. Furthermore, the expression of DEGs associated with AP2/EREBP and WRKY transcription factors and heat shock proteins was upregulated in CSSL1283. In addition, several genes encoding protein kinase were differentially expressed between Xu178 and CSSL1283. Our study provided a genetic resource for the dissection of the molecular mechanisms of ear-length development and for uncovering candidate genes to increase maize ear length.
The Estimation of Taylor-Quinney Coefficients Using Small Ring Specimens
Authors: Lavie W.J. , Rouse J.P. , Hyde C.J. 
Published: December 2022

Abstract
Background
The use of the Taylor-Quinney coefficient for introducing a thermal dissipation term into material models relies on understanding its dependencies. These are usually determined through extensive experimentation, wherein temperature variations are monitored in a test piece during mechanical loading.

Objective
This study aims to reduce the cost and time necessary to determining the dependencies of the Taylor-Quinney coefficient by proposing a novel small specimen inverse testing method and demonstrating its use on aluminium alloy 7175.

Methods
The method proposed is based on mechanical testing of a novel small ring specimen in parallel with FEA simulations. In the experiments, small rings of 7175-T7351 aluminium alloy, 20 mm in outer diameter, were loaded between two pins for different pin displacement rates (namely 1, 1.5 and 2 mm/s) at room temperature and the local specimen temperature field was monitored using an infra-red thermal camera. Fully coupled thermal-mechanical simulations of the tests were performed using a range of Taylor-Quinney coefficients, and the resulting temperature evolutions compared to the experimental results in order to determine appropriate coefficient values for the material.

Results
The method presented shows good repeatability and allows for clear observation of thermal dissipation. Taylor-Quinney values ranging 0.51-0.59 are reported for the 7175 alloy, in line with values reported in the literature for similar alloys. Density, specific heat capacity and thermal conductivity, fundamental thermal material properties necessary for the simulations, are also reported for the alloy.

Conclusions
The method detailed shows promise for determining Taylor-Quinney coefficients in a wide range of experimental conditions and is proposed as a cheap and fast alternative to full-scale specimen testing of Taylor-Quinney coefficients. Taylor-Quinney values obtained for 7175 aluminium are shown to be much lower than the value of 0.9 often proposed for materials.

Cerebellar Degeneration Impairs Strategy Discovery but Not Strategy Recall
Authors: Tsay Jonathan S. , Schuck Lauren , Ivry Richard B. 
Published: December 2022

Abstract
The cerebellum is recognized to play a critical role in the automatic and implicit process by which movement errors are used to keep the sensorimotor system precisely calibrated. However, its role in other learning processes frequently engaged during sensorimotor adaptation tasks remains unclear. In the present study, we tested the performance of individuals with cerebellar degeneration on a variant of a visuomotor adaptation task in which learning requires the use of strategic re-aiming, a process that can nullify movement errors in a rapid and volitional manner. Our design allowed us to assess two components of this learning process, the discovery of an appropriate strategy and the recall of a learned strategy. Participants were exposed to a 60° visuomotor rotation twice, with the initial exposure block assessing strategy discovery and the re-exposure block assessing strategy recall. Compared to age-matched controls, individuals with cerebellar degeneration were slower to derive an appropriate aiming strategy in the initial Discovery block but exhibited similar recall of the aiming strategy during the Recall block. This dissociation underscores the multi-faceted contributions of the cerebellum to sensorimotor learning, highlighting one way in which this subcortical structure facilitates volitional action selection.
The Court of Justice of the European Union in the Case Law of the Polish Constitutional Court: The Current Breakdown in View of Polish Constitutional Jurisprudence Pre-2016
Authors: Sołtys Agnieszka 
Published: December 2022

AbstractThe current crisis in the relationship between the Polish Constitutional Court and the Court of Justice of the European Union (ECJ) is of crucial significance for the process of regional integration based on the values of liberal democracy taking place in the EU. The constitutional crisis in Poland that began in the end of 2015 has challenged the systemic position of the Polish Constitutional Court. It resulted in a new model of constitutional adjudication, and in this new model the Constitutional Court, stripped of its counter-majoritarian power, cannot be perceived as the guardian of liberal democracy. This article postulates that the assessment of the present case law of the Polish Constitutional Court in European matters is made through the prism of the Constitutional Court’s jurisprudence pre-2016 (i.e. before the constitutional crisis). Based on that assumption, the current reversal in the case law of the Polish Constitutional Court concerning the ECJ is analysed and assessed. It is argued that the root cause of the constitutional crisis in Poland is the departure from the principles of liberal democracy in the jurisprudence of the Constitutional Court, which are foundational—in light of the assumptions of the integration process—for the axiological identity of the EU and its Member States. This article also shows how the principles and concepts developed in the Polish constitutional jurisprudence pre-2016 could have served to avoid the current conflict with the ECJ, and how those notions are misused in the current jurisprudence of the Polish Constitutional Court.
Quantitative and Qualitative Assessment of As-Cast Microstructure and Microporosity of γ-γ′ Co-based Superalloys
Authors: Migas Damian , Roskosz Stanisław , Moskal Grzegorz 
Published: December 2022

AbstractThe γ-γ′ Co-based alloys have attracted extensive attention as a new class of materials for high temperature applications. The work is focused on quantitative and qualitative microstructural characterization of selected γ-γ′ type Co-based superalloys obtained by gravity casting. The four Co-based alloys were prepared via vacuum induction melting. The microstructure was analyzed by means of light microscopy and scanning electron microscopy. The microstructural parameters such as porosity and secondary dendrite arm spacing (SDAS) were evaluated by image analysis. The new Co-based superalloys are characterized by proper as-cast microstructure owing to low SDAS and limited microporosity. The values of secondary dendrite arm spacing are comparable for all alloys. The W-free alloys containing Mo and Nb exhibit substantially lower shrinkage porosity compared to those of Co–Al–W and Co–Ni–Al–W. Due to crystallization of Mo and Nb rich phases at lower temperatures, these alloys are characterized by higher solidification range.
Coastal Salinity and Water Management Practices in the Bengal Delta: A Critical Analysis to Inform Salinisation Risk Management Strategies in Asian Deltas
Authors: Feist Sean E. , Hoque Mohammad A. , Ahmed Kazi M. 
Published: December 2022

AbstractSalinisation within delta environments is a dynamic process governed by the interaction between coastal, fluvial and geomorphological systems. Increasingly, these have been modified through human activity and management practices, which lead to unintended problems associated with waterlogging and salt accumulation in soils and water resources. As a result of these issues, over 100 million people in the Ganges–Brahmaputra and other Asian deltas are negatively affected by a lack of freshwater availability and decreased crop yields. Rising sea levels, climate change, and population increase are all likely to exacerbate these problems. Using an iterative approach of literature review, we analyse the evolution of water management practices and policy and how these have influenced salinity within the delta, with a conceptual framework of understanding developed to guide risk management strategies. We find that management of coastal flooding and salinisation is hampered by socio-economic conditions and the dynamic hydro-morphology of the delta, which has increasingly been altered through diversion and abstraction of upstream flow. Whilst engineering solutions protect large areas from inundation, interruption of natural flood-dynamics also increases the potential impact from storm-surge and fluvio-tidal flooding. To limit salinity, policies based on salinisation science, as well as the implementation of adequately financed, multi-layered, integrated risk management plans at the local, regional, and river basin levels, are required. The promotion of stakeholder engagement should be encouraged to ensure local co-operation and effective implementation of policies. The mitigation of the multiple and cascading hazards associated with salinisation caused by anthropogenic activity, climate change and socio-economic development is crucial for the populations of delta regions across Asia.
Trends in carbon capture technologies: a bibliometric analysis
Authors: Ritchie Sean , Tsalaporta Elena 
Published: December 2022

AbstractClimate change is an ever-present issue, which has a vast variety of potential solutions, one of which being carbon capture. This paper aims to use bibliometric analysis techniques to find trends in carbon capture within the technologies of adsorption, absorption, membranes, and hybrid technologies. The Web of Science core collection database performed bibliometric searches, with the ‘Bibliometrix’ plug-in for R software, performing the bibliometric analysis. Bibliometric data spanned across 1997–2020 and the investigation found that adsorption technologies dominated this period in terms of citations and articles, with hybrid technologies being the least produced but rising in scientific productivity and citations. The Analysis found China and the United States of America to be the dominant producers of articles, with global collaboration being central to carbon capture. The ‘International Journal of Greenhouse Gas Control’ ranked as the top producer of articles however, the ‘ACS Applied Materials & Interfaces’ was the leading journal in terms of H-index.
Elements of a design method – a basis for describing and evaluating design methods
Authors: Gericke Kilian , Eckert Claudia , Stacey Martin 
Published: December 2022

AbstractMethod development is at the heart of design research as methods are a formalised way to express knowledge about how aspects of design could or should be done. However, assuring that methods are in fact used in industry has remained a challenge. Industry will only use methods that they can understand and that they feel will give them benefit reliably. To understand the challenges involved in adopting a method, the method needs to be seen in context: it does not exist in isolation but forms a part of an ecosystem of methods for tackling related design problems. A method depends on the knowledge and skills of the practitioners using it: while a description of a method is an artefact that is a formalisation of engineering knowledge, a method in use constitutes a socio-technical system depending on the interaction of human participants with each other as well as with the description of the method, representations of design information and, often, tools for carrying out the method’s tasks. This paper argues that crucial factors in the adoption of methods include how well they are described and how convincingly they are evaluated. The description of a method should cover itscore idea, therepresentationsin which design information is described, theprocedureto be followed, itsintended use, and thetoolsit uses. The account of a method’s intended use should cover itspurpose, the situations or product types within itsscope, itscoverageof kinds of problems within its scope, itsexpected benefitandconditionsfor its use. The different elements need to be evaluated separately as well as the method as an integrated whole. While verification and validation are important for some elements of methods, it is rarely possible to prove the validity of a method. Rather the developers of methods need to gather sufficient evidence that a method will work within a clearly articulated scope. Most design methods do not have binary success criteria, and their usefulness in practice depends as much on simplicity and usability as on the outcomes they produce. Evaluation should focus on how well they work, and how they can be customised and improved.
