description: Given a matrix $A$, a linear feasibility problem (of which linear classification is a special case) aims to find a solution to a primal problem $w: A^Tw > \textbf{0}$ or a certificate for the dual problem which is a probability distribution $p: Ap = \textbf{0}$. Inspired by the continued importance of "large-margin classifiers" in machine learning, this paper studies a condition measure of $A$ called its \textit{margin} that determines the difficulty of both the above problems. To aid geometrical intuition, we first establish new characterizations of the margin in terms of relevant balls, cones and hulls. Our second contribution is analytical, where we present generalizations of Gordan's theorem, and variants of Hoffman's theorems, both using margins. We end by proving some new results on a classical iterative scheme, the Perceptron, whose convergence rates famously depends on the margin. Our results are relevant for a deeper understanding of margin-based learning and proving convergence rates of iterative schemes, apart from providing a unifying perspective on this vast topic.

description: The purpose of this study is to identify socio-psychological, cultural and physical motivations among domestic and foreign participants in a marathon event staged in the vicinity of a World Heritage Site in the City of Yogyakarta, Central Java, Indonesia. The study also aims to investigate the differences in motivation between the two types of participants. It emphasizes the importance of gaining international cross-cultural perspectives in motivations, as the marathon is organized to be part of the city’s strategies to attract visitors. It is expected that better knowledge of the participants' motivations and needs can help organizers develop marketing strategies that will boost attendance and loyalty. This research uses a descriptive-explorative method with a quantitative approach in which primary data were obtained from domestic and foreign participants and field observations. This study gives empirical support to socio-psychological motives that serve as push factors, cultural motives from the destination as pull factors and physical motives that are based on self-determination theory. On the cross-cultural perspectives of these motivations, only cultural motivations differed significantly between the two types of participants. This study then presents managerial implications on facilitating foreign participants to engage better in the cultural festivities, which is found to be one of the main motives to participate.

description: A multiplicatively closed, horizontal foliation on a Lie groupoid may be viewed as a "pseudoaction" on the base manifold $M$. A pseudoaction generates a pseudogroup of transformations of $M$ in the same way an ordinary Lie group action generates a transformation group. Infinitesimalizing a pseudoaction, one obtains the action of a Lie algebra on $M$, possibly twisted. A global converse to Lie's third theorem proven here states that every twisted Lie algebra action is integrated by a pseudoaction. When the twisted Lie algebra action is complete it integrates to a twisted Lie group action, according to a generalization of Palais' global integrability theorem.

description: The present research aims to listen to a group of stakeholders and the different territorial visions, proposing the creation of a new cooperation model that simultaneously serves the needs of the Tua Valley region and the expectations of its actors and contributes to the success of the Tua Valley Regional Natural Park's Astrotourism Project. Eight representatives of regional organisations were interviewed to ascertain their vision of networks, their involvement in any similar cooperation system, ways these entities operate within them and networks' advantages and disadvantages. The interviewees were also asked about their potential contributions and predictions in relation to the creation of a new collaborative network in the surrounding inland region. The results reveal that most stakeholders are familiar with this organisational concept as they have already integrated similar models into their operations, and the interviewees outlined the associated advantages and difficulties. These stakeholders support the development of a new Tua Valley network, in which must rely on a culture of sharing and mutual trust to meet its members and the region's needs and reflect their specificities. The findings can be used to foster new synergies based on the quintuple helix model, serving as a starting point for further research on networks in tourism and contributing to the enrichment of the relevant existing literature.

In particular, we prove that the group $\mathrm{Aut}^{\#}X$ of complex automorphisms of $X$ which act trivially on the Picard group of $X$ is a linear algebraic group defined over $\mathbb R$.

Year: 2022

description: This study examines airports as an essential tool in the strategic and marketing plans of Spanish destinations, but we are aware that every tool has a mathematical and social divergence. In the case of Spanish airports, these have been the Gates of Paradise of the Spanish tourist destination, but at the same time they have become the controller of the future of many Spanish tourist destinations, in which they condition the economy, urban planning and the labor and social scenario of the natives of that territory. The first objective is to analyze the hegemony of airports as a link to entry to the Spanish destinations, whereas, the airport and destination are communicating vessels that favor the tourist growth of Spain, but this has created a high dependence on destinations in their short and long-term plan. The second objective is to evaluate whether there are other alternatives for short and long-distance transport that reduce competition in the Spanish air sector. Finally, the third objective is to examine whether the record of tourist arrivals to Spain through airports is good for the strategic plans of Destination Management Organizations that stress quality. This correlation is not always feasible and acceptable in tourist destinations.

description: We consider the asymmetric formulation of quantum hypothesis testing, where two quantum hypotheses have different associated costs. In this problem, the aim is to minimize the probability of false negatives and the optimal performance is provided by the quantum Hoeffding bound. After a brief review of these notions, we show how this bound can be simplified for pure states. We then provide a general recipe for its computation in the case of multimode Gaussian states, also showing its connection with other easier-to-compute lower bounds. In particular, we provide analytical formulas and numerical results for important classes of one- and two-mode Gaussian states.

description: O presente artigo apresenta as considerações de uma pesquisa voltada ao viés da Semiótica do Turismo, com foco na Interdisciplinaridade. Vinculada a esta linha de pesquisa, analisa-se de forma exploratória e interpretativa o contexto das linguagens artístico-culturais presentes nos espaços culturais no entorno do Teatro Amazonas no bairro Centro de Manaus enquanto oferta para as práticas turísticas locais. Os respectivos espaços culturais escolhidos para essa pesquisa foram: "Ateliê 23", "Casarão de Idéias", "Galeria do Largo", "Palácio da Justiça", e "Casa das Artes". Estes lugares abrigam aspectos distintos que variam entre as artes do teatro, das artes visuais, do cinema, da literatura e afins, apresentando diferentes perspectivas de um centro histórico vivo e habitado cujas artes representam um diferenciado ângulo do cotidiano da sociedade manauara e amazonense. Os resultados apresentam as dinâmicas culturais variadas que são comumente excluídas do setor do turismo local ao ausentá-las de mapas turísticos e roteiros pela cidade. Foram utilizados métodos de ilustração para melhor abordar a importância da imagem nos estudos da Semiótica do Turismo e para apresentar algumas linguagens artístico-culturais presentes no centro histórico de Manaus. Após a pesquisa, foi concluído que há uma grande diversidade de ofertas que não são absorvidas pelo trade turístico manauara que poderia renovar as atividades do campo do turismo para manter uma atenção maior no espaço urbano da cidade, gerando renda para a comunidade local e um conhecimento mais profundo do visitante com as culturas e as artes amazonenses.

description: The stability of tunnel cross passages excavated in soft soil has always been a major challenge. In recent years, new techniques based on the installation of pre-reinforcements before tunnel excavation have been developed to control excavation-induced deformation and surface settlements. In this paper, a finite element numerical simulation was conducted to study the reduction effect of an umbrella vault element modelled as a homogenized area on the deformations induced after the excavation of a cross passage. The results of this study show that the ground deformations can be controlled efficiently by using this type of pre-reinforcement. However, the findings showed that there is no effect of the umbrella arch length on the reduction of the ground deformations. This paper represents a very good demonstration of 3D modelling of tunnel junctions using pre-support techniques; it is the most advanced/appropriate research tool for studying the behaviour of cross passages and is useful as a paradigm for other researchers and practitioners.

description: Abstract: SARS-CoV-2 is a recently emerged zoonotic beta-coronavirus that has become the cause of a global pandemic. In response to this pandemic, an international collaborative effort has been established to produce models of the SARS-CoV-2 lifecycle and host responses to infection, the COVID-19 Disease Mapping Consortium. Alongside this group we have produced a pair of graphical and computational models of the SARS-CoV-2 lifecycle covering viral entry into a host cell, the replication cycle of the virus, interactions between viral replication and host defence pathways and the release of daughter virions in both lung epithelial and macrophages cells. These models have been built in the yEd network editing software using the modified Edinburgh Pathway Notation (mEPN) scheme. In addition to supporting the graphical representation of biological pathways, the mEPN scheme supports computational modelling without simplification of the graphical elements. The modelling system is based on stochastic Petri nets where place nodes represent biological entities and transition nodes represent the interactions between them. Activity is represented by the rule-based flow of tokens. Simulations are performed using the tool BioLayout (http://biolayout.org/). The events depicted within these models have been produced from information available in the literature and Informed by models produced by other members of the Disease Mapping Consortium. The models produced by this project are sufficiently computationally detailed for use in drug target identification and elimination, with sufficient graphical detail and clarity to function as educational tools covering the SARS-CoV-2 lifecycle and its interaction with the Toll-like Receptor 3 and Interferon signalling pathways. We have also demonstrated that these host defence systems and the three currently included drug species significantly influence the behaviour of these models. The effects of these systems are comparable to those expected from their in vivo counterpoints, indicating that this model is suitable as a tool for in silico experimentation with SARS-CoV-2 replication.

description: Plastic waste has become a significant challenge for waste managers currently. Recycling is an important measure to reduce the associated environmental impacts. However, the recycling rate for plastic waste is low. As a notably contextual and collectivist society, China is a major consumer and waste treater of plastics. In this context, social capital may be a vital factor of Chinese plastic recycling behavior (PRB) but without enough attention. This study explores the role and mechanism of social capital on Chinese residents’ PRB based on an extended Theory of Planned Behavior model. Primary data collected from 803 residents in China was used to test the model empirically. The results show that social capital (trust, social norms and social networks) significantly influence PRB. Furthermore, personal norms and attitude are mediators between social capital and PRB. Additionally, perceived behavioral control weaken the effect of social norms on PRB.

We report the efficient and simultaneous generation of second and third harmonic by the nanoparticles. On this basis, we set up a novel imaging protocol based on the co-localization of the two harmonic signals and demonstrate its benefits in terms of increased selectivity against endogenous background sources in tissue samples. Finally, we discuss the use of BFO nanoparticles as mapping reference structures for correlative light-electron microscopy.

description: Scott proved in 1997 that for any tree $T$, every graph with bounded clique number which does not contain any subdivision of $T$ as an induced subgraph has bounded chromatic number. Scott also conjectured that the same should hold if $T$ is replaced by any graph $H$. Pawlik et al. recently constructed a family of triangle-free intersection graphs of segments in the plane with unbounded chromatic number (thereby disproving an old conjecture of Erdős). This shows that Scott's conjecture is false whenever $H$ is obtained from a non-planar graph by subdividing every edge at least once. It remains interesting to decide which graphs $H$ satisfy Scott's conjecture and which do not. In this paper, we study the construction of Pawlik et al. in more details to extract more counterexamples to Scott's conjecture. For example, we show that Scott's conjecture is false for any graph obtained from $K_4$ by subdividing every edge at least once. We also prove that if $G$ is a 2-connected multigraph with no vertex contained in every cycle of $G$, then any graph obtained from $G$ by subdividing every edge at least twice is a counterexample to Scott's conjecture.

description: The X-ray binary 4U 1543$-$624 has been provisionally identified as an ultracompact system with an orbital period of $\simeq$18~min. We have carried out time-resolved optical imaging of the binary to verify the ultra-short orbital period. Using 140\,min of high-cadence $r'$-band photometry we recover the previously-seen sinusoidal modulation and determine a period $P=18.20\pm0.09$\,min. In addition, we also see a 7.0$\times 10^{-4}$\,mag\,min$^{-1}$ linear decay, likely related to variations in the source's accretion activity. Assuming that the sinusoidal modulation arises from X-ray heating of the inner face of the companion star, we estimate a distance of 6.0--6.7\,kpc and an inclination angle of 34$^{\circ}$--61$^{\circ}$ (90\% confidence) for the binary. Given the stability of the modulation we can confirm that the modulation is orbital in origin and 4U 1543$-$624 is an ultracompact X-ray binary.

description: Understanding phase transitions in quantum matters constitutes a significant part of present day condensed matter physics. Quantum phase transitions concern ground state properties of many-body systems, and hence their signatures are expected to be pronounced in low-energy states. Here we report signature of a quantum critical point manifested in strongly out-of-equilibrium states with finite energy density with respect to the ground state and extensive (subsystem) entanglement entropy, generated by an external pulse. These non-equilibrium states are evidently completely disordered (e.g., paramagnetic in case of a magnetic ordering transition). The pulse is applied by switching a coupling of the Hamiltonian from an initial value ($λ_{I}$) to a final value ($λ_{F}$) for sufficiently long time and back again. The signature appears as non-analyticities (kinks) in the energy absorbed by the system from the pulse as a function of $λ_{F}$ at critical-points (i.e., at values of $λ_{F}$ corresponding to static critical-points of the system). As one excites higher and higher eigenstates of the final Hamiltonian $H(λ_{F})$ by increasing the pulse height ($|λ_{I} - λ_{F}|$), the non-analyticity grows stronger monotonically with it. This implies adding contributions from higher eigenstates help magnifying the non-analyticity, indicating strong imprint of the critical-point on them. Our findings are grounded on exact analytical results derived for Ising and XY chains in transverse field.

description: Purpose: This cross-sectional study explored home participation of children with and without cerebral palsy aged 7–18 years and the effect of the environment on this participation. Method: A convenience sample of 110 children with cerebral palsy (55% males; mean age 12.7 years) and 134 children without cerebral palsy (49% males; mean age 12.0 years) was included. Parents completed the Participation and Environment Measure for Children and Youth. Mann–Whitney U-test, χ2 tests and radar plots were used to analyze item-level differences between two groups. Participation of children with cerebral palsy was analyzed subsequently in relation to their functional limitations using the Spearman’s rank correlation. Results: Children with cerebral palsy participated in home activities less than children without cerebral palsy did, as perceived by their parents. The least differences were observed in activities that typically did not require much physical engagement. Number of activities done at home and the involvement level mostly correlated with fine manual and intellectual functioning. Barriers included physical layout, factors related to the activity (physical and cognitive demands), and limited resources (services, information, money). Conclusions: It is important to understand the uniqueness of each home environment in order to enhance participation of children with cerebral palsy in home setting.IMPLICATIONS FOR REHABILITATIONThe child’s relationships with family members, social demands of activities and attitudes and actions of others, as supportive factors, should be considered by professionals to facilitate home participation.There is the need to develop strategies to facilitate children’s independence in order to optimize participation outcomes in home-based activities.Differences identified in this study may assist professionals in the design of a context that improves home participation of children with cerebral palsy.

In particular we consider mild function solutions to abstract Cauchy problems and show that the unique solution is Hölder continuous in time with values in a suitable fractional Sobolev space. As this analysis is done via a-priori estimates, we can apply this result to stochastic PDEs on metric measure spaces and solve the equation in a pathwise sense for almost all paths. The main example of noise term is of fractional Brownian type and the metric measure spaces can be classical as well as given by various fractal structures. The whole approach is low dimensional and works for spectral dimensions less than 4.

description: The climate crisis is accelerating at an unprecedented rate which can be overcome by depicting pro-environmental behaviors in personal, household, and industrial consumption areas. Grounded on the social ideal theory, the current study aims to examine the direct as well as the indirect impact of Environmental Knowledge (EK) and Environmental Concern (EC) on citizens’ Pro-Environmental Behavior (PEB) while studying Perceived Environmental Responsibility (PER) as a mediator. Moreover, the moderating role of Knowledge Sharing (KS) has also been investigated between EK and PEB. Surveying 581 citizens of twin cities, i.e. Rawalpindi and Islamabad, Pakistan, at two different times. Results depicted that citizens’ EK and EC positively and significantly impact their PEB directly as well as through an underlying mechanism of PER. Moreover, the interactive effect of KS with EK has been found to enhance citizens’ PEB. Overall, this research brings multiple theoretical and policy implications with future research directions.

description: We present the ultrarelativistic boost of the general global monopole solution which is parametrized by mass and deficit solid angle. The problem is addressed from two different perspectives. In the first one the primary object for performing the boost is the metric tensor while in the second one the energy momentum tensor is used. Since the solution is sourced by a triplet of scalar fields that effectively vanish in the boosting limit we investigate the behavior of a scalar field in a simpler setup. Namely, we perform the boosting study of the spherically symmetric solution with a free scalar field given by Janis, Newman and Winicour. The scalar field is again vanishing in the limit pointing to a broader pattern of scalar field behaviour during an ultrarelativistic boost in highly symmetric situations.

description: Opening and maintaining public access to the coast, as it is for any coastal management agencies in the US, has long been one of the prime missions of the California Coastal Commission. In this article, we ask: what are the administrative agendas latent in coastal access in California? Using webscraping, we collected over 10,000 staff reports prepared by the Commission between 1996 and 2016 and examined how the agency used the permitting process to attain its missions. Using the topic modeling technique, we identified 18 key administrative agendas in the staff reports pertaining to public access. These agendas reveal a wide spectrum of environmental protection strategies that the Commission pursued along with maintaining public access. While some of these topics narrowly focus on coastal accessibility (e.g. easements, trails and paths), and utilization (e.g. recreational activities, piers, parking), many of them extend beyond and cover broader, more controversial environmental agendas, such as shoreline and sensitive habitat protection. We also explored the stability of these administrative agendas over time. We observed notable stability in these efforts in the past two decades, despite personnel changes.
Chip-firing games on Eulerian digraphs and NP-hardness of computing the rank of a divisor on a graph

description: Baker and Norine introduced a graph-theoretic analogue of the Riemann-Roch theory. A central notion in this theory is the rank of a divisor. In this paper we prove that computing the rank of a divisor on a graph is NP-hard. The determination of the rank of a divisor can be translated to a question about a chip-firing game on the same underlying graph. We prove the NP-hardness of this question by relating chip-firing on directed and undirected graphs.

description: This study aims to unravel the environmental effects of institutional quality in relationship with China’s Foreign Direct Investment (FDI) in Belt and Road Initiative (BRI) countries. The empirical analysis is conducted over the period 2003–2018, using the System-GMM approach with the Windmeijer finite-sample correction. We infer that China’s FDI has a detrimental effect on environmental quality, which validates the ‘pollution haven hypothesis’ in the BRI region. Importantly, the interaction effect of China’s FDI with indicators of institutional quality yields negative and significant results. This entails that strong institutions can boost the quality of the environment through FDI attractiveness. In further assessment, the threshold levels of institutional quality are calculated, beyond which China’s FDI can reduce carbon emissions in the BRI region. This substantiates both the pollution haven and pollution halo hypotheses. The study underscores the importance of institutional reform in the quest for sustainable development, owing to the fact that most economies prioritize FDI-led growth strategies.

description: Revealed and stated preference techniques are widely used to assess willingness to pay (WTP) for non-market goods as input to public and private decision-making. However, individuals first have to satisfy subsistence needs through market good consumption, which affects their ability to pay. We provide a methodological framework and derive a simple ex post adjustment factor to account for this effect. We quantify its impacts on the WTP for non-market goods and the ranking of projects theoretically, numerically and empirically. This confirms that non-adjusted WTP tends to be plutocratic: the views of the richest – whatever they are – are more likely to impact decision-making, potentially leading to ranking reversal between projects. We also suggest that the subsistence needs-based adjustment factor we propose has a role to play in value transfer procedures. The overall goal is a better representation of the entire population’s preferences with regard to non-market goods.
Convex Modeling of Interactions with Strong Heredity

description: We consider the task of fitting a regression model involving interactions among a potentially large set of covariates, in which we wish to enforce strong heredity. We propose FAMILY, a very general framework for this task. Our proposal is a generalization of several existing methods, such as VANISH [Radchenko and James, 2010], hierNet [Bien et al., 2013], the all-pairs lasso, and the lasso using only main effects. It can be formulated as the solution to a convex optimization problem, which we solve using an efficient alternating directions method of multipliers (ADMM) algorithm. This algorithm has guaranteed convergence to the global optimum, can be easily specialized to any convex penalty function of interest, and allows for a straightforward extension to the setting of generalized linear models. We derive an unbiased estimator of the degrees of freedom of FAMILY, and explore its performance in a simulation study and on an HIV sequence data set.

description: The global pandemic has reshaped the use of working space dramatically, mainly due to the implementation of the working from home policy and indoor social distancing requirements. This calls for the rethinking of the current office design approaches and the proposal of specific design strategies to provide a safer and healthier environment for employees to return to their offices. Also, the demand for enhancing office design to accommodate special and rare events like the pandemic is identified. More resilient and flexible office designs are needed for the post- pandemic era. This study aims to provide an insight into the human movement in the open-plan office setting by simulating the movement using agent-based modelling. Normal scenario and special scenarios with social distancing standards and reduced office capacity are simulated. The simulated scenarios contribute to the development of the new adaptive office design approaches for a safe office resume.
