Phases of a phenomenological model of twisted bilayer graphene

We propose a lattice scale two-band generalized Hubbard model as a caricature of the electronic structure of twisted bilayer graphene. Various possible broken symmetry phases can arise, including a nematic phase (which is a form of orbital ferromagnet) and an orbital-triplet spin-singlet superconducting phase. Concerning the mechanism of superconductivity -- we propose an analogy with superconductivity in alkali-doped C$_{60}$ in which a violation of Hund's first rule plays a central role.
Two-Stage Double Bootstrap Data Envelopment Analysis for Efficiency Evaluation of Shared-Bicycle Stations in Urban Cities

To optimize the performance and operation of shared-bicycle systems, this study aims to evaluate the efficiency of shared-bicycle stations and to find factors affecting their efficiency scores. We analyzed the efficiency of 1,260 shared-bicycle stations in the City of Seoul using shared-bicycle rental and trajectory data as of June 2018. In this study, the two-stage bootstrap data envelopment analysis, which is a non-parametric frontier technique, was applied to estimate each shared-bicycle station’s efficiency. In the first stage, we evaluated efficiency scores by employing the number of bicycle racks and bicycle path ratio as input variables, and bicycle turnover rate and balancing rate as output variables. The efficiency scores were regressed on potential covariates using a bootstrapped truncated regression in the second stage. From our results, the efficiencies of shared-bicycle stations were found to be diverse depending on the nature of land use around the station location. The results present evidence to show that shared-bicycle stations located in residential and school-dominated areas are likely to be efficient, whereas those in semi-industrial areas, commercial, and business districts are generally inefficient. Furthermore, the effect of variables like the commuting population, the number of registered vehicles, and the number of bicycle-related accidents per year were statistically significant, thus affecting shared-bicycle station performance. This study offers essential insights into the efficiency of shared-bicycle stations, which could be incorporated into shared-transportation strategies to improve mobility in urban cities.
An Empirical analysis of the determinants of greenhouse gas voluntary disclosure in Australia

Based on a comprehensive theoretical framework, we investigate the determinants of greenhouse gas emission (GHG) voluntary disclosure of non GHG registered companies. Previous studies assessed the determinants of GHG voluntary disclosure of firms subject to environmental regulation, risk and liabilities. We also employ proxies of voluntary disclosure theory and agency theory in addition to the stakeholder theory and legitimacy theory used in prior studies. The content analysis for the period 2009 to 2011 shows a positive association between GHG voluntary disclosure, firm size and corporate governance. Further, firms with superior GHG performance are more likely to engage in discretionary disclosure, and listing status plays a significant role in GHG disclosure decision which suggests that stakeholders’ interests also determine disclosure decisions.
Review of Commitment Theories and Models: Application to an Emerging Profession

The purpose of this research project is to explore if traditional explanations of organizational and professional commitment and conflict, which have been developed through research of older and more established professions such as the Accounting profession, also apply to the Human Resource profession. Survey data gathered from HR practitioners are used to examine the correlates of organizational and professional commitment and conflict. Study results indicate the models explain a significant portion of the variation in both organizational and professional commitment, and that the two types of commitment have different antecedent factors. Results also indicate that organizational and professional conflict is lowest when both levels of organizational and professional commitment are high. Theoretical and practical implications are discussed.
The Sustainable Development Goals in Scientific Literature: A Bibliometric Overview at the Meta-Level

In 2015, the UN adopted the Sustainable Development Goals (SDGs), addressing social, environmental, and economic targets. Global partnerships, transnational, and interdisciplinary research are essential for achieving progress towards the SDGs. This study analyzes 4593 research articles at the meta-level, explicitly referring to the SDGs. This a comparably small amount of research items directly addressing the goals. However, comparisons with existing approaches using different queries are possible. Research that links to the SDGs through its title, keywords, or abstract facilitates knowledge sharing on the goals as it is easier to identify relevant work. Using scientometric means, we assessed the corresponding sources, research areas, affiliated countries, thematic foci, and the availability of funding acknowledgments. The results are useful for identifying research gaps and potential collaboration possibilities. The outcomes suggest that most research referring to the SDGs comes from the research areas Life Sciences & Biomedicine and Social Sciences. The most predominant SDG among the analyzed research articles is SDG 3 (“good health and well-being”). A relatively high share of open access articles contributes to the idea of knowledge sharing for the SDGs. Nearly 37% of all articles count as international publications, i.e., as being co-authored by authors from affiliations of multiple countries.
Crisis communication via social media : the interplay of sender, crisis type and brand type

In the last decade social media has become increasingly part of strategic crisis communication, due to its dialogic nature as well as its far reach and speediness to spread messages. Yet, classical crisis communication research has neglected the factors influencing crisis communication via social media. This study contributes to this research field by experimentally investigating to what extend the sender, either brand or traditional media, and the crisis type, either symbolic or functional, affect the outcomes of a crisis message for brands. Furthermore, brand type is investigated as a moderator and cultural differences were considered. Results indicate that disclosure of a crisis message by the brand lessens the negative effects of the crisis on brand reputation and the attitude towards the brand. Moreover, if the crisis is related to the values and ethics of the brand, brand-disclosure becomes even more favourable than in a crisis related to product failure. Also, results show that neither sender nor crisis type affect the likelihood with which consumers engage in secondary crisis communication (e.g. sharing of the message) or secondary crisis reaction (e.g. boycotting the brand). Lastly, functional brands are more likely to be boycotted due to a symbolic crisis and cultural differences have significant effects in crisis communication.
Traditional Cautery: A Narrative Review on New Lights through Old Window

Cautery is a traditional healing practice used in many medico-surgical conditions since ancient times with variable efficacy [1-3]. Cautery similar to moxibustion in Traditional Chinese Medicine (TCM) has a checkered history and developed after the discovery of fire [4]. Fire is linked with healing power, and as a ritual also worshiped in certain cultures of the world [4-6]. Diverse olden cultures progressively developed and improved traditional cautery, its definition, procedures, and techniques with safety measures, shapes, forms, and materials other than fire such as oil and ligatures used in traditional cautery practice [1,2,4,7]. Furthermore, advancements were also made in identifying indications, contraindications, adverse effects and complications associated with cautery [1,2,4-6]. Though the research was in infantile phase during ancient times, published data collected through case reports, case series and traditional healers’ impressive observations over thousands of centuries helped significantly in the advancements of traditional cautery and cauterization process. This research landscape of ancient times has changed robustly over the past three decades or so. Many sophisticated rigor research supported by international health organizations are now conducted globally in complementary, alternative and integrative medicine. Research also contributed to the refinement of traditional cautery (old window) and its new lights in terms of modern surgical devices. Overall, traditional cautery is still used in many health conditions around the world by folk healers and professionals, and until now they remain the strong promoters of sustaining its cost effective safe practice.
ABA in Germanic verbs June 2018 ( * ) ABA in Germanic verbs

This paper discusses cases where non-adjacent cells in morphological paradigms are syncretic, commonly called ABA patterns (Bobaljik 2012 et seqq.). Data from verbs in Germanic languages are examined, as earlier work suggests that a *ABA constraint may be active in this domain. It will be shown that there are verbs in several Germanic languages which exhibit genuine ABA patterns, precluding an analysis based on a constraint *ABA. It is suggested that the rarity of ABA patterns should instead be given a diachronic explanation in terms of Proto-Germanic conjugation classes. This approach is independently motivated by frequency asymmetries in modern Germanic languages, and correctly predicts where ABA patterns are more likely to appear. The research reported here adds to a rapidly-growing body of work on extralinguistic explanations for typological asymmetries (Anderson 2016), suggesting that formal linguistic constraints may have little or no role to play in this domain.
High-pressure EXAFS measurements of crystalline Ge using nanocrystalline diamond anvils

High-pressure extended x-ray absorption fine structure (EXAFS) measurements on crystalline Ge demonstrate that the use of nanocrystalline diamond anvils can solve the glitch problem from single crystal diamond anvils and improve the quality of the data. Our results indicate that using nanocrystalline diamond anvils for high-pressure EXAFS research can provide a large enough energy range for structural study up to four coordination shell distances. In particular, we obtained the pressure evolution of mean square relative displacement for the first neighbor shells of crystalline Ge and observed different correlation effects for different coordination shells. The use of nanocrystalline diamond anvils will provide a breakthrough for high-pressure EXAFS study, especially for amorphous compounds in which only limited structural information can be obtained by diffraction techniques.
Physical properties and microstructure of butter cake addedwith Persea americana puree

The effect of addition of avocado (Persea americana) puree on the physical and microstructure of butter cake was studied. Butter cakes were made by replacing butter with 10, 30 and 50% of avocado puree. Physical properties including batter specific gravity, volume, colour and image analysis of cellular structure of the crumb were analyzed. Texture profile analysis was determined using texture analyzer. The results showed that with the increased amount of avocado puree, the batter specific gravity increased while volume of the cakes reduced. The texture profile analysis showed that the cakes became harder as the amount of avocado puree increased, while cohesiveness was not affected. The cellular structure of the crumb exhibited a decrease in the number of air cells while the average cell size increased with addition of avocado puree. The colour analysis showed that the cake crumb became darker as the aavocado puree was increased.
Elliptic beta integrals and solvable models of statistical mechanics

The univariate elliptic beta integral was discovered by the author in 2000. Recently Bazhanov and Sergeev have interpreted it as a star-triangle relation (STR). This important observation is discussed in more detail in connection to author's previous work on the elliptic modular double and supersymmetric dualities. We describe also a new Faddeev-Volkov type solution of STR, connections with the star-star relation, and higher-dimensional analogues of such relations. In this picture, Seiberg dualities are described by symmetries of the elliptic hypergeometric integrals (interpreted as superconformal indices) which, in turn, represent STR and Kramers-Wannier type duality transformations for elementary partition functions in solvable models of statistical mechanics.
An Embedded Corrector Problem for Homogenization. Part I: Theory

This article is the first part of a two-fold study, the objective of which is the theoretical analysis and numerical investigation of new approximate corrector problems in the context of stochastic homogenization. We present here three new alternatives for the approximation of the homogenized matrix for diffusion problems with highly-oscillatory coefficients. These different approximations all rely on the use of an embedded corrector problem (that we previously introduced in [Canc\`es, Ehrlacher, Legoll and Stamm, C. R. Acad. Sci. Paris, 2015]), where a finite-size domain made of the highly oscillatory material is embedded in a homogeneous infinite medium whose diffusion coefficients have to be appropriately determined. The motivation for considering such embedded corrector problems is made clear in the companion article [Canc\`es, Ehrlacher, Legoll, Stamm and Xiang, in preparation], where a very efficient algorithm is presented for the resolution of such problems for particular heterogeneous materials. In the present article, we prove that the three different approximations we introduce converge to the homogenized matrix of the medium when the size of the embedded domain goes to infinity.
Various fungal communities colonise the functional wood tissues of old grapevines externally free from grapevine trunk disease symptoms

Background and Aims The objective of this study was to analyse the various fungal communities that colonise functional wood tissues of old vines that did not express symptoms of grapevine trunk diseases (i.e. Esca and Eutypa dieback) in the year of sampling. Plants of the cultivar Baco Blanc a grapevine hybrid of Folle Blanche and Noah used to produce Armagnac in France were sampled. Methods and Results Forty-two and 58-year-old vines, planted in the same vineyard, were uprooted, cut longitudinally and their functional wood tissues sampled. Culture-dependent and single-strand conformational polymorphism methods were used to compare the fungal communities colonising these wood tissues. It was shown that the fungal communities were significantly different depending on the age of the grapevines. A total of 421 fungal strains were isolated and identified by internal transcribed spacer region sequencing. Conclusions Many grapevine trunk diseases fungal pathogens, particularly the causal agents of Esca (42-year-old vines) and Eutypa dieback (58-year-old vines), as well as numerous potentially plant-beneficial mycoparasites (e.g. Trichoderma spp.), were isolated from the functional wood tissues of old grapevines. Significance of the Study The lack of foliar symptoms among older grapevines may reflect an ‘equilibrium’ among trunk fungal pathogens, mycoparasites and saprobes in the functional wood tissues of trunks.
Mechanical induced wounds in fish – a review on models and healing mechanisms

Skin wounds and injuries are frequently occurring in farmed fish, particularly in more intensive production systems. Any disruptions of the skin, such as mucus removal, scale loss or deeper incisions, are negatively correlated with barrier functions and disease resistance. In this review, the current knowledge on mechanically induced wounds in fish is dedicated to five areas of focus: (i) The anatomy and functions of fish skin, (ii) Techniques to inflict mechanical skin damage in farmed and laboratory fish for experimental purposes, (iii) Healing mechanisms of deep wounds, (iv) In vitro models for wound healing studies and (v) Wound care, with focus on factors that may enhance or delay skin regenerative processes. The aim of the review was to presents key points for a better understanding of skin resilience and fish robustness, with focus on Atlantic salmon, Salmo salar, in Norwegian coastal production environment.

Numerical Modeling of Instream Wood Transport, Deposition, and Accumulation in Braided Morphologies Under Unsteady Conditions: Sensitivity and High‐Resolution Quantitative Model Validation

Large wood promotes fundamental changes in river hydraulics and morphology, playing a relevant role in river ecology but also in flood hazard. Accurate predictions of large wood dynamics in terms of deposition patterns and travel distance are still lacking and only recently have numerical models been developed to this end. In this work we enhance the capabilities of the numerical model Iber‐Wood in reproducing large wood dynamics in shallow braided rivers and validate it by comparing simulations with the results of previous laboratory experiments. The flume experiments provide high‐resolution observations of wood travel distances and depositional patterns of wood. The comparison proves useful to improve the numerical simulation of (i) the interactions between wood pieces and the riverbed (e.g., when wood pieces are transported by dragging), (ii) wood pieces with roots, and (iii) the formation of wood jams (i.e., accumulations of greater than three wood pieces). A sensitivity analysis reveals the crucial role of bed topography, with limited effect played by drag and restitution coefficients. Taking advantage of a controlled environment with similar simplifying hypotheses, we combine the strengths of both physical and numerical modeling to explore the parameters that are most effective in controlling wood dynamics. We use the numerical model to explore the effect of unsteady flow conditions, with different wood supply input. The resulting wood depositional patterns, jam formation, and travel distances during floods may improve our understanding of some of the controls on biogeomorphic evolutionary trajectories of braided rivers.
Mentalizing: What’s language got to do with it?

ABSTRACT Understanding that people’s ideas may be false is a challenging step in Theory of Mind (ToM) development, which is accomplished around the age of 4–5 years old by typically developing (TD) children. False-belief attribution remains difficult beyond this age for certain clinical populations, such as Autism Spectrum Disorder (ASD), where delays in this realm are significant, and Developmental Language Disorder (DLD), where delays tend to be subtler. Research has identified links between ToM success and language skills, in particular complement clauses such as John thought/said that aliens landed in his garden, in TD, as well as in ASD and DLD. It has been hypothesized that these structures serve as tools for representing subjective truths. This article reports results from our experimental work further examining the link between complementation and ToM. Study 1 investigates if complements have a more privileged influence on ToM in ASD and TD children than abilities such as Executive Functions, which arguably also play a role. Study 2 determines if complementation skills in ASD support ToM reasoning or are merely implied in ToM task performance. Study 3 extends the evaluation of complementation in ToM reasoning to DLD and explores whether clinical groups of different etiologies—ASD and DLD—perform comparably for ToM once they have similar complementation skills, as expected by a linguistic determinism approach. Study 4 addresses speculation that complementation training may not be efficient to trigger improved ToM in instances of ToM impairments by empirically testing whether training on complements via a newly created iPad application can be useful for ToM remediation in both ASD and DLD. Taken together, this body of work both enhances our theoretical understanding of the language-cognition interface as well as widens our repertoire of clinical tools addressing difficulties in this domain.
PERFORMANCE AND EMISSION CHARACTERISTIC OF MINIATURE TURBOJET ENGINE FED JET A-1/ALCOHOL BLEND

This paper presents differences between fossil fuel (Jet A-1) and alcohol/Jet A-1 blend, during combustion process using laboratory test rig with miniature turbojet engine (MiniJETRig). The test rig has been created in Air Force Institute of Technology for research and development works aimed at alternative fuels for aviation. Fuel from different feedstock (non-fossil sources) is introduced into market due to ecological aspects, fuel price stability and energy security. Application of alcohol to propel aircraft has started form using a blend of aviation gasoline with ethanol in spark-ignited internal-combustion engines. Taking into account that large part of aviation fuels used by commercial aircraft is jet fuels, so in this area it has begun to look for possibilities to apply alcohol component. In 2016, international standard (ASTM) approved a synthetic blending component for aviation turbine fuels for use in civil aircraft and engines – alcohol-to-jet synthetic paraffinic kerosene (ATJ-SPK). According to standard, ATJ-SPK synthetic blending components shall be comprised hydro processed synthetic paraffinic kerosene wholly derived from isobutanol processed through dehydration, oligomerization, hydrogenation and fractionation. Two different fuel samples, a traditional fossil jet fuel (Jet A-1) and a blend of 10% butanol with Jet A-1 were tested. Laboratory tests of selected physicochemical properties and bench tests with the same profile of engine test were carry out for both fuel samples. The obtained results: engine parameters and exhaust gas emissions are compared and discussed.
