description: We present a theoretical description of the London penetration depth of a multi-band superconductor in the case when both superconducting and spin-density wave orders coexist. We focus on clean systems and zero temperature to emphasize the effect of the two competing orders. Our calculation shows that the supefluid density closely follows the evolution of the superconducting order parameter as doping is increased, saturating to a BCS value in the pure superconducting state. Furthermore, we predict a strong anisotropic in-pane penetration depth induced by the spin-density wave order.

Fracturing graphene by chlorination: a theoretical viewpoint

description: Motivated by the recent photochlorination experiment [B. Li et al., ACS Nano 5, 5957 (2011)], we study theoretically the interaction of chlorine with graphene. In previous theoretical studies, covalent binding between chlorine and carbon atoms has been elusive upon adsorption to the graphene basal plane. Interestingly, in their recent experiment, Li et al. interpreted their data in terms of chemical bonding of chlorine on top of the graphene plane, associated with a change from sp2 to sp3 in carbon hybridization and formation of graphene nanodomains. We study the hypothesis that these domains are actually fractured graphene with chlorinated edges, and compare the energetics of chlorine-containing graphene edge terminations, both in zigzag and armchair directions, to chlorine adsorption onto infinite graphene. Our results indicate that edge chlorination is favored over adsorption in the experimental conditions with radical atomic chlorine and that edge chlorination with sp3-hybridized edge carbons is stable also in ambient conditions. An ab initio thermodynamical analysis shows that the presence of chlorine is able to break the pristine graphene layer. Finally, we discuss the possible effects of the silicon dioxide substrate on the chlorination of graphene.

description: We consider the full Dicke spin-boson model composed by a single bosonic mode and an ensemble of $N$ identical two-level atoms with different couplings for the resonant and anti-resonant interaction terms, and incorporate a dipole-dipole interaction between the atoms. Assuming that the system is in thermal equilibrium with a reservoir at temperature $β^{-1}$, we compute the free energy in the thermodynamic limit $N\rightarrow\infty$ in the saddle-point approximation to the path integral and determine the critical temperature for the superradiant phase transition. In the zero temperature limit, we recover the critical coupling of the quantum phase transition, presented in the literature.

description: We revisit the classical problem of diffusion-limited ion transport to a membrane (or electrode) by considering the effects of charged side walls. Using simple mathematical models and numerical simulations, we identify three basic mechanisms for over-limiting current in a microchannel: (i) {\it surface conduction} carried by excess counterions, which dominates for very thin channels, (ii) convection by {\it electro-osmotic flow} on the side walls, which dominates for thicker channels and transitions to (iii) {\it electro-osmotic instability} on the membrane end in very thick channels. These intriguing electrokinetic phenomena may find applications in biological separations, water desalination, and electrochemical energy storage.

description: The overall objective of FAIRsFAIR is to accelerate the realization of the goals of the EOSC by opening up and sharing all knowledge, expertise, guidelines, implementations, new trajectories, courses and education on FAIR matters. To support this, FAIRsFAIR is tasked to set up a single FAIR Data Stewardship Competence Centre which this report defines as a shared hub of expertise in implementing FAIR data stewardship principles, offering leadership, coordination and cataloging services to connect relevant people, guidance, learning resources and curricula in different thematic areas. Requirements for competence centres in general and a core competence centre for FAIR data stewardship in general were identified by interviewing other members of the FAIRsFAIR project to understand their expectations for a core competence centre as well as the resources they will contribute to the knowledge base. Furthermore, we carried out a broad characterisation of current competence centres enriched with case studies of good examples for certain aspects of a competence centre. We created user stories for how stakeholders might interact with the competence centres and refined them through an open consultation answered by 106 people, interviews with EOSC clusters, and feedback gathered in workshops at the Open Science Fair 2019. Based on the description of work and our research, we have identified the following priorities for competence centres in general and the FAIRsFAIR core Competence Centre in particular: Advisory Create a catalogue of resources to support FAIR data stewardship Provide a help desk to support FAIR data stewardship Provide a networking tool to support FAIR data stewardship Harmonisation Apply emerging standards to describe learning resources in FAIR data stewardship Encourage economy of scale through deploying the same tools and certifying services addressing FAIR data needs Dissemination Develop training and guidance materials on FAIR data stewardship topics currently not covered Develop curation policies for the content aggregated and developed by the FAIRsFAIR Data Stewardship Competence Centre Deliver training on core competencies for FAIR data stewardship

description: We observe that the dominant one loop contribution to the graviton propagator in the theory of N (N>>1) light scalar fields ϕ_a (with masses smaller than M_{pl}/\sqrt{N}) minimally coupled to Einstein gravity is proportional to N while that of graviton-scalar-scalar interaction vertex is N independent. We use this to argue that the coefficient of the Rϕ_a^2 term appearing at one loop level is 1/N suppressed. This observation provides a resolution to the η-problem, that the slow-roll parameter ηreceives order one quantum loop corrections for inflationary models built within the framework of scalar fields minimally coupled to Einstein gravity, for models involving large number of fields. As particular examples, we employ this to argue in favor of the absence of η-problem in M-flation and N-flation scenarios.

description: We study the structure of entanglement in a supersymmetric lattice model of fermions on certain types of decorated graphs with quenched disorder. In particular, we construct models with controllable ground state degeneracy protected by supersymmetry and the choice of Hilbert space. We show that in certain special limits these degenerate ground states are associated with local impurities and that there exists a basis of the ground state manifold in which every basis element satisfies a boundary law for entanglement entropy. On the other hand, by considering incoherent mixtures or coherent superpositions of these localized ground states, we can find regions that violate the boundary law for entanglement entropy over a wide range of length scales. More generally, we discuss various desiderata for constructing violations of the boundary law for entanglement entropy and discuss possible relations of our work to recent holographic studies.

Conceptual framework

description: Smart services offer great innovation potential by incorporating digital technologies into non-digital value-creation processes. As smart service innovation poses significant challenges to organizations, existing research has contributed to understanding and addressing this phenomenon by developing various methods, tools, and processes. Yet, the academic community often still fails to bridge the “last mile” and help practitioners apply this knowledge in their specific application contexts. This article outlines how research can empower practitioners by systematically providing methodological knowledge for smart service innovation. We review and contrast existing methodologies and present a conceptual framework for value co-creation through smart service innovation methodologies. In addition, we identify six essential resource types required in these methodologies and propose emergent research avenues to guide future contributions to smart service innovation research.

The Impact of Corporate Social Responsibility on Business Performance in the Maritime and Logistics Industries in India
Creators: name: GABRIEL
Publisher: name: ISAR Publisher
Year: 2023
Subjects: CSR, Corporate Social Responsibility, Maritime, Logistic, India

description: This article explores the profound influence of Corporate Social Responsibility (CSR) on business performance within India's maritime and logistics sectors, emphasizing the regulatory framework, exemplary case studies, benefits, and challenges. Focusing on two leading companies, Adani Ports and Special Economic Zone (APSEZ) and Mahindra Logistics, it examines their CSR initiatives and how they have integrated responsible business practices into their operations. The regulatory framework, primarily driven by the Companies Act of 2013, has made CSR not only a compliance requirement but a strategic imperative. It mandates certain companies to allocate a portion of their profits for CSR activities, demonstrating India's commitment to responsible business conduct. Exemplifying the benefits of CSR, APSEZ and Mahindra Logistics have established themselves as role models in the industry. Their CSR initiatives have led to enhanced reputation, operational efficiency, investor attraction, and employee satisfaction. These initiatives, including healthcare, education, and environmental sustainability, have not only improved the well-being of local communities but also positively impacted the companies' overall performance. However, CSR integration is not without its challenges. Compliance and accurate reporting can be administratively complex, and companies must carefully balance profitability with CSR investments. In conclusion, the integration of CSR into India's maritime and logistics industries is a strategic necessity. APSEZ, Mahindra Logistics, and other exemplary companies showcase the transformative power of CSR, contributing to a brighter, more responsible future for the sectors, society, and aligning with global sustainability goals.
Singular and Plural Functions for Functional Logic Programming

Publisher: name: arXiv
Year: 2012
Subjects: subject: Programming Languages (cs.PL)
subject: FOS: Computer and information sciences

description: Functional logic programming (FLP) languages use non-terminating and non-confluent constructor systems (CS's) as programs in order to define non-strict non-determi-nistic functions. Two semantic alternatives have been usually considered for parameter passing with this kind of functions: call-time choice and run-time choice. While the former is the standard choice of modern FLP languages, the latter lacks some properties---mainly compositionality---that have prevented its use in practical FLP systems. Traditionally it has been considered that call-time choice induces a singular denotational semantics, while run-time choice induces a plural semantics. We have discovered that this latter identification is wrong when pattern matching is involved, and thus we propose two novel compositional plural semantics for CS's that are different from run-time choice. We study the basic properties of our plural semantics---compositionality, polarity, monotonicity for substitutions, and a restricted form of the bubbling property for constructor systems---and the relation between them and to previous proposals, concluding that these semantics form a hierarchy in the sense of set inclusion of the set of computed values. We have also identified a class of programs characterized by a syntactic criterion for which the proposed plural semantics behave the same, and a program transformation that can be used to simulate one of them by term rewriting. At the practical level, we study how to use the expressive capabilities of these semantics for improving the declarative flavour of programs. We also propose a language which combines call-time choice and our plural semantics, that we have implemented in Maude. The resulting interpreter is employed to test several significant examples showing the capabilities of the combined semantics. To appear in Theory and Practice of Logic Programming (TPLP)

description: Especially in highly developed, technology-oriented countries like Germany, knowledge-intensive services contribute significantly to prosperity and growth. Existing methods and tools for managing knowledge-intensive services rarely live up to the fast-moving demands and complex interactions. This is especially due to specific features of these services such as customer integration, uncertainties or the high degree of novelty. With regard to these requirements, new methods and tools are needed in order to analyse and model such service systems. Design Structure Matrices (DSM) are a promising method for modelling weakly-structured service processes. Additionally, they enable the integration of static and dynamic features. Using a process simulation approach the service model is transformed into a discrete event simulation, thereby allowing a holistic analysis and assessment. This approach supports service managers in making well-founded decisions, even in complex situations and under uncertainty. In a case-study, an excerpt from a high-tech based service of a chemical plant development, the modelling according to the DSM-methodology and exemplary results of the simulation are presented and discussed.

description: Using a novel electrochemical phase-field model, we question the common belief that LixFePO4 nanoparticles separate into Li-rich and Li-poor phases during battery discharge. For small currents, spinodal decomposition or nucleation leads to moving phase boundaries. Above a critical current density (in the Tafel regime), the spinodal disappears, and particles fill homogeneously, which may explain the superior rate capability and long cycle life of nano-LiFePO4 cathodes.

Towards Supporting Business Process Compliance Checking with Compliance Pattern Catalogues - A Financial Industry Case Study
Creators: name: Delfmann, Patrick
name: Hübers, Michael
Publisher: name: Gesellschaft für Informatik e.V. (The German Informatics Society)
Year: 2015

description: Business process compliance checking serves to discover legal or self-regulatory violations in business processes using process models. This way, companies can react to new regulations and avoid violations quickly, hence prevent negative monetary or even legal consequences. In the business process compliance management literature, we find an abundance of approaches supporting business process compliance checking. Although many of these approaches show promise to support business process compliance checking by providing model checking-like methodologies, hardly any of them provide a common list of relevant compliance rules or violations that should be checked for. With this paper, we aim at making a step towards comprehensive catalogues of compliance rules that can be used as input for business process compliance checking approaches. In particular, we analyse two legal documents providing a set of compliance rules for service processes in financial industries. We derive compliance patterns from them and apply them to a large business process model coming from a German IT service provider for banks, using a graph pattern-based compliance checking approach. As a result, we show that deriving business process compliance rules from legal texts leads to meaningful patterns matching several subsections of common process models of financial services. Hence, we can expect catalogues of such patterns to be promising for supporting business process analysts in compliance checking.

description: We present Spitzer IRAC and MIPS observations of the star-forming region containing intermediate-mass young stellar object (YSO) AFGL 490. We supplement these data with near-IR 2MASS photometry and with deep SQIID observations off the central high extinction region. We have more than doubled the known membership of this region to 57 Class I and 303 Class II YSOs via the combined 1-24 um photometric catalog derived from these data. We construct and analyze the minimum spanning tree of their projected positions, isolating one locally over-dense cluster core containing 219 YSOs (60.8% of the region's members). We find this cluster core to be larger yet less dense than similarly analyzed clusters. Although the structure of this cluster core appears irregular, we demonstrate that the parsec-scale surface densities of both YSOs and gas are correlated with a power law slope of 2.8, as found for other similarly analyzed nearby molecular clouds. We also explore the mass segregation implications of AFGL 490's offset from the center of its core, finding that it has no apparent preferential central position relative to the low-mass members.

description: IT Service Catalogues (ITSCs) make an important contribution to the administration and distribution of IT products. It is often particularly difficult to draw up a structural concept of an IT Service Catalogue, as appropriate examples are scarce. In the future, advanced ITSCs will be especially important in attracting external customers. So, a practical structure for the ITSC is important. Different perspectives and approaches for structuring an ITSC can be found in the literature, but the total number of works on this topic is relatively small. This article combines an analysis of the literature with consultation of business experts to determine the requirements for ITSC structuring and to formulate a design proposal. This stands out due to several levels of description in combination with a view concept, through which opposing needs can be met. The proposal is illustrated by means of a case study.

TechCare Dairy Sheep Welfare Assessment Measures
Creators: name: Al., Cathy Dwyer Et
Publisher: name: Zenodo
Year: 2023

description: A description of animal-based measures and their definition as used in the dairy sheep studies by TechCare. These are NOT intended to be a comprehensive protocol for assessing overall welfare of dairy sheep but are individual measures of different welfare issues as identified by the TechCare stakeholders as the most important issues for their industry. As far as possible these are validated indicators drawn from a number of different studies (particularly the Animal Welfare Indicators (AWIN) project, national projects), which were considered the best methods to measure each issue by the TechCare WP2 team. Indicators are described in two ways: firstly for measures that can be taken in the field in undisturbed animals (typically extensively managed animals where it would not be feasible for desirable to need to handle the animals frequently) and secondly for those that can be made at close quarters, likely with some handling required (e.g. restraint). Indicators are measured at the level of the individual animal. This is required to allow validation of the sensor measures (which are recorded at the animal level). Thus, each animal must be identifiable at close quarters and at a distance if the field measures are to be used.

description: Suppliers of Product-Service Systems (PSS) pursue the objective of creating long-term customer relationships. In order to achieve that, PSS in Business to Business (B2B) markets need to be designed as a tool for PSS suppliers and clients, supporting them in achieving their certain business goals. One approach can be applied by identifying common goals and aligning all PSS-related management activities. This paper shows how this approach can be designed in a systematic way. Therefore, a consecutive framework for the development and configuration management of customer-specific PSS in B2B markets is derived. Applying it to a case study of food industry, the framework’s relevance and its transferability into practice is demonstrated.

description: Non-Gaussian noise transients in interferometric gravitational-wave detectors increase the background in searches for short-duration and un-modelled signals. We describe a method for vetoing noise transients by ranking the statistical relationship between triggers in auxiliary channels that have negligible sensitivity to gravitational waves and putative gravitational-wave triggers in the detector output. The novelty of the algorithm lies in its hierarchical approach, which leads to a minimal set of veto conditions with high performance and low deadtime. After a given channel has been selected it is used to veto triggers from the detector output, then the algorithm selects a new channel that performs well on the remaining triggers and the process is repeated. This method has been demonstrated to reduce the background in searches for transient gravitational waves by the LIGO and Virgo collaborations.

description: Combining cognitive radio technology with user cooperation could be advantageous to both primary and secondary transmissions. In this paper, we propose a first relaying scheme for cognitive radio networks (called "Adaptive relaying scheme 1"), where one relay node can assist the primary or the secondary transmission with the objective of improving the outage probability of the secondary transmission with respect to a primary outage probability threshold. Upper bound expressions of the secondary outage probability using the proposed scheme are derived over Rayleigh fading channels. Numerical and simulation results show that the secondary outage probability using the proposed scheme is lower than that of other relaying schemes. Then, we extend the proposed scheme to the case where the relay node has the ability to decode both the primary and secondary signals and also can assist simultaneously both transmissions. Simulations show the performance improvement that can be obtained due to this extension in terms of secondary outage probability.

description: As the usage of 3D models increases, so does the importance of developing accurate 3D shape retrieval algorithms. A common approach is to calculate a shape descriptor for each object, which can then be compared to determine two objects' similarity. However, these descriptors are often evaluated independently and on different datasets, making them difficult to compare. Using the SHREC 2011 Shape Retrieval Contest of Non-rigid 3D Watertight Meshes dataset, we systematically evaluate a collection of local shape descriptors. We apply each descriptor to the bag-of-words paradigm and assess the effects of varying the dictionary's size and the number of sample points. In addition, several salient point detection methods are used to choose sample points; these methods are compared to each other and to random selection. Finally, information from two local descriptors is combined in two ways and changes in performance are investigated. This paper presents results of these experiment

title: Spanish language teachers' mediation practices in Higher Education

description: The discussion of the concept ‘mediation’ in foreign language education has rapidly increased over the last few years. However, mediation from the teacher’s point of view and their agency in mediation processes in the foreign language classroom is a field that still requires further exploration. In response to the need to get a better understanding of how language teachers actually create opportunities for their learners to establish connections between languages and cultures, this thesis aims to explore the explicit mechanisms used by Spanish teachers in higher education (HE) when they mediate target language and culture in online and face-to-face teaching practices. For this research, a deliberately small sample of four Spanish practitioners in HE was selected, and a first-hand corpus of naturally occurring instances of mediation in the classroom is analysed through an inductive constructivist approach informed by thematic analytic methods. The methodology applied follows an interpretive inquiry model using qualitative methods and it includes different tools: classroom observations, stimulated recall (SR) sessions and interviews. The analysis of the examples of mediation practices in the classroom indicate that the strategies used are overlapping and multilayered which allow the creation of an effective, multidimensional way to facilitate mediation for students. Hence, this study offers empirical and detailed evidence of real instances of mediation strategies in language classrooms in HE in the UK, and it breaks new ground by discovering how this is achieved in practice through combining different strategies together. It finds that mediation has multiple implications for language teacher education, and discusses the further implications for foreign language teacher training in the light of the results of this research.

description: In this paper, rough approximations of Cayley graphs are studied and rough edge Cayley graphs are introduced. Furthermore, a new algebraic definition called pseudo-Cayley graphs containing Cayley graphs is proposed. Rough approximation is expanded to pseudo-Cayley graphs. Also, rough vertex pseudo-Cayley graphs and rough pseudo-Cayley graphs are introduced. Some theorems are provided, form which some properties such as connectivity and optimal connectivity are derived. This approach opens a new research field in sciences such as data networks.

description: Cho et al. [Phys. Rev. B, 84, 174502 (2011)] have reported on the temperature dependence of the London penetration depth deduced from Tunnel Diode Oscillator (TDO) measurements in optimally doped Fe(Se,Te) single crystals. According to their analysis, these measurements chould suggest a nodeless two-gap pairing symmetry with strong pair breaking effects. However, to reach this conclusion, the authors fit the temperature dependence of the superfluid density with a two band {\it clean} limit model which is incompatible with the presence of strong pair breaking effects, deduced from the $T^n$ temperature dependence of the London penetration depth below $T_c/3$. Moreover they claim that their results are also ruling out the suggestion that surface conditions can significantly affect the TDO data but this conclusion is based on one very specific damaging process, and is completely ignoring the large dispersion in the previously published TDO data.
