description: The timed pattern matching problem is an actively studied topic because of its relevance in monitoring of real-time systems. There one is given a log $w$ and a specification $\mathcal{A}$ (given by a timed word and a timed automaton in this paper), and one wishes to return the set of intervals for which the log $w$, when restricted to the interval, satisfies the specification $\mathcal{A}$. In our previous work we presented an efficient timed pattern matching algorithm: it adopts a skipping mechanism inspired by the classic Boyer--Moore (BM) string matching algorithm. In this work we tackle the problem of online timed pattern matching, towards embedded applications where it is vital to process a vast amount of incoming data in a timely manner. Specifically, we start with the Franek-Jennings-Smyth (FJS) string matching algorithm---a recent variant of the BM algorithm---and extend it to timed pattern matching. Our experiments indicate the efficiency of our FJS-type algorithm in online and offline timed pattern matching.

description: This study reviews the current photographic tourism literature to identify what fields within tourism have been studied by researchers, the contexts, the samples used, the sampling methods employed, the photographic methods and supporting methods used, the data analysis techniques applied and the countries studied. A set of 115 relevant academic articles were selected and assessed using content analysis. The findings showed that overall publications in the field of photographic tourism increased after 1997, with a notable rise in tourism management research in this area. Tourist perceptions, tourist behaviours and destination image were the most frequently researched topics. Literature material was generally preferred over tourist samples. Purposive sampling was the most common sampling method. The main photographic data collection method was researcher-found imagery. Many studies used interviews as an accompanying method. Critical analysis was more common in North American research while statistical approaches were employed more often in Asian studies.

description: The intuition suggested by the Drake equation implies that technology should be less prevalent than biology in the galaxy. However, it has been appreciated for decades in the SETI community that technosignatures could be more abundant, longer-lived, more detectable, and less ambiguous than biosignatures. We collect the arguments for and against technosignatures' ubiquity and discuss the implications of some properties of technological life that fundamentally differ from nontechnological life in the context of modern astrobiology: It can spread among the stars to many sites, it can be more easily detected at large distances, and it can produce signs that are unambiguously technological. As an illustration in terms of the Drake equation, we consider two Drake-like equations, for technosignatures (calculating N(tech)) and biosignatures (calculating N(bio)). We argue that Earth and humanity may be poor guides to the longevity term L and that its maximum value could be very large, in that technology can outlive its creators and even its host star. We conclude that while the Drake equation implies that N(bio)>>N(tech), it is also plausible that N(tech)>>N(bio). As a consequence, as we seek possible indicators of extraterrestrial life, for instance, via characterization of the atmospheres of habitable exoplanets, we should search for both biosignatures and technosignatures. This exercise also illustrates ways in which biosignature and technosignature searches can complement and supplement each other and how methods of technosignature search, including old ideas from SETI, can inform the search for biosignatures and life generally.

description: In this paper, we propose a device to device (D2D) communication scenario underlaying a cellular network where both D2D and cellular users (CUs) are discrete power-rate systems with limited feedback from the receivers. It is assumed that there exists an adversary which wants to eavesdrop on the information transmission from the base station (BS) to CUs. Since D2D communication shares the same spectrum with cellular network, cross interference must be considered. However, when secrecy capacity is considered, the interference caused by D2D communication can help to improve the secrecy communications by confusing the eavesdroppers. Since both systems share the same spectrum, cross interference must be considered. We formulate the proposed resource allocation into an optimization problem whose objective is to maximize the average transmission rate of D2D pair in the presence of the cellular communications under average transmission power constraint. For the cellular network, we require a minimum average achievable secrecy rate in the absence of D2D communication as well as a maximum secrecy outage probability in the presence of D2D communication which should be satisfied. Due to high complexity convex optimization methods, to solve the proposed optimization problem, we apply Particle Swarm Optimization (PSO) which is an evolutionary approach. Moreover, we model and study the error in the feedback channel and the imperfectness of channel distribution information (CDI) using parametric and nonparametric methods. Finally, the impact of different system parameters on the performance of the proposed scheme is investigated through simulations. The performance of the proposed scheme is evaluated using numerical results for different scenarios.

Starting from a simple SysML/UML behavioral model of the system requirements, three formal models have been developed using three different frameworks, namely UMC, ProB, and CADP/LNT. The paper shows how the different ways to represent and analyze the system from the three different points of view allow us to take advantage of the resulting diversity.

description: To study the effect of parity-violation on the rate of complexity growth, by using "Complexity=Action" conjecture, we find the complexity growth rates in different solutions of the chiral theory of Topologically Massive Gravity (TMG) and parity-preserving theory of New Massive Gravity (NMG). Using the results, one can see that decreasing the parameter $μ$, which increases the effect of Chern-Simons term and increases chirality, would increase the rate of growth of complexity. Also one can observe a stronger correlation between complexity growth and temperature rather than complexity growth and entropy. At the end we comment on the possible meaning of the deforming term of chiral Liouville action for the rate of complexity growth of warped CFTs in the Tensor Network Renormalization picture.

description: This paper proposes a framework for integrating data plane (DP) acceleration within the Network Functions Virtualization (NFV) architecture. Data plane programming (DPP) proves to be beneficial for NFV environments, as it provides full packet forwarding flexibility through the use of self-designed algorithms. Additionally, DPP provides high-performance networking, as the DP can be configured to execute specific functions on dedicated hardware. We present an integration of the DP acceleration within the ETSI NFV architecture that leverages custom DP functions implemented in hardware switches using P4 language. Besides, OpenStack and Kubernetes are used as Virtualized Infrastructure Managers (VIMs) and Open Source MANO (OSM) as the Management and Orchestration (MANO) element.

description:
Exposure to comprehensive sex education shows promise in preventing sexual violence and sexual harassment (SVSH) perpetration and victimization and supporting survivors. Determining if these benefits are also found in communities experiencing high levels of SVSH, such as lesbian, gay, bisexual, transgender and queer (LGBTQ+) communities, is needed. Utilizing a sequential explanatory mixed-methods study design, we assessed LGBTQ + undergraduates’ exposure to sex education (SE), what SE sources they relied on, and SE’s perceived usefulness and responsivity to LGBTQ + needs. Compared to their non-LGBTQ + peers, LGBTQ + students perceived SE as less helpful in navigating personal desires (t294 = 2.08, p < .05) and sexual consent (t295= 2.15, p < .05). LGBTQ + students were more likely to use media (e.g., internet, pornography) as their primary source of SE on topics such as violence in relationships and consent. In-depth interviews substantiated quantitative findings, highlighting the non-responsiveness of SE among LGBTQ + students and further revealed that having to supplement SE through media increased LGBTQ + students’ vulnerability to SVSH (including online sexual coercion). Via interviews, LGBTQ + students reported formal SE to be non-inclusive, led to experiences of othering, silencing, erasure, and made them more vulnerable to SVSH and related outcomes. SE policy and education must be modified to be more inclusive and helpful for LGBTQ + students, especially relating to SVSH prevention.

description: Göttsche-Nakajima-Yoshioka K-theoretic blowup equations characterize the Nekrasov partition function of five dimensional $\mathcal{N}=1$ supersymmetric gauge theories compactified on a circle, which via geometric engineering correspond to the refined topological string theory on $SU(N)$ geometries. In this paper, we study the K-theoretic blowup equations for general local Calabi-Yau threefolds. We find that both vanishing and unity blowup equations exist for the partition function of refined topological string, and the crucial ingredients are the $\bf r$ fields introduced in our previous paper. These blowup equations are in fact the functional equations for the partition function and each of them results in infinite identities among the refined free energies. Evidences show that they can be used to determine the full refined BPS invariants of local Calabi-Yau threefolds. This serves an independent and sometimes more powerful way to compute the partition function other than the refined topological vertex in the A-model and the refined holomorphic anomaly equations in the B-model. We study the modular properties of the blowup equations and provide a procedure to determine all the vanishing and unity $\bf r$ fields from the polynomial part of refined topological string at large radius point. We also find that certain form of blowup equations exist at generic loci of the moduli space.

description: One of the more apparent consequences of sea level rise in coastal zone is the increased migration of salt water inland. This study investigates the intrusion of the salt water in coastal rivers in the south west region of Bangladesh. An existing Hydrodynamic model is used and new components have been developed to integrate: river and floodplain salinity transports. The Integrated model have been validated and applied to the study area. The results have been found to be consistent in estimating river flow and salinity. The Integrated model discloses a model that considers major components of the hydrologic cycle.

description: We propose a novel ultrasonic sensor structure composed of Cantilever arm structure slot dual-micro-ring resonators(DMRR).We present a theoretical analysis of transmission by using the coupled mode theory.The mode field distributions and sound pressure distributions of transmission spectrum are obtained from 3D simulations based on Comsol Multi-physics(COMSOL)method.Our ultrasonic sensor exhibit theoretical sensitivity as high as 1462.5mV/kPa,which is 22 times higher than that of single slot-based micro-ring ultrasonic sensor.Our ultrasonic sensor offers higher sensitivity and a larger detection frequency range than conventional piezoelectric based ultrasound transducer.The results show that the sensing characteristics of our system can be optimized through changing the position and the angle of sound field.Our ultrasonic sensor with an area of 25um*60um, the-factor can be approximately 1540 with radius of 5um We detect an angular range of -90o to 90o and a minimum distance of 0.01um. Finally,we calculate the Cantilever arm structure slot DMRR array ultrasonic sensor's optical performance. Our proposed design provides a promising candidate for a hydrophone.

description: Utilizing multiwavelength observations and magnetic field data from SDO/AIA, SDO/HMI, GOES and RHESSI, we investigate a large-scale ejective solar eruption of 2014 December 18 from active region NOAA 12241. This event produced a distinctive three-ribbon flare, having two parallel ribbons corresponding to the ribbons of a standard two-ribbon flare, and a larger-scale third quasi-circular ribbon offset from the other two ribbons. There are two components to this eruptive event. First, a flux rope forms above a strong-field polarity-inversion line and erupts and grows as the parallel ribbons turn on, grow, and spread part from that polarity-inversion line; this evolution is consistent with the tether-cutting-reconnection mechanism for eruptions. Second, the eruption of the arcade that has the erupting flux rope in its core under goes magnetic reconnection at the null point of a fan dome that envelops the erupting arcade, resulting in formation of the quasi-circular ribbon; this is consistent with the breakout reconnection mechanism for eruptions. We find that the parallel ribbons begin well before (12 min) circular ribbon onset, indicating that tether-cutting reconnection (or a non-ideal MHD instability) initiated this event, rather than breakout reconnection. The overall setup for this large-scale (circular-ribbon diameter 100000 km) eruption is analogous to that of coronal jets (base size 10000 km), many of which, according to recent findings, result from eruptions of small-scale minifilaments. Thus these findings confirm that eruptions of sheared-core magnetic arcades seated in fan-spine null-point magnetic topology happen on a wide range of size scales on the Sun.

description: This research paper aims at examining the concept of green building with the objective of identifying the key factors that affect the growth of green building in the construction industry. A comprehensive literature review was undertaken to provide an overview of the factors limiting the growth of green building globally. A quantitative approach was adopted and data was collected via a questionnaire survey of randomly selected construction professionals in the Gwalior construction industry. This paper is aim to analyze the factors which are mostly responsible for factors limiting the growth of green building. In order to do so a literature survey is conducted that gives the desired factors which leads to limiting the growth of green building construction. The factors are derived by a detailed literature survey. In the end, an investigation is completed by using the process Important Index (IMPI) which gives the relative importance of these factors which help in ranking those factors according to their IMPI The paper will add value to construction industry stakeholders who have limited information regarding factors limiting the growth of green building.

description: This article presents a comprehensive analysis of China’s outward foreign direct investment (OFDI) in Africa, examining its economic impact and technology spillover effects. Drawing on a review of relevant literature, the study systematically explores the influence of China’s OFDI on technological progress and efficiency in the selected African countries. Using panel data from 29 African countries over the period 2004-2019, this article computes the total factor productivity of the African countries and then empirically analyzes the Chinese OFDI technological spillover effect. The results demonstrate a significant and positive impact of China’s OFDI on technology use and advancement in these countries. The study’s conclusion summarizes the key findings and offers important policy recommendations. Overall, this research contributes to the ongoing discourse on China’s role in Africa’s economic development and enhances our understanding of the factors influencing China’s outbound investment decisions.
Analytic model for tangential YORP

description: The tangential YORP effect (TYORP) plays a significant role in the dynamical evolution of asteroids, and up to now has only been studied numerically. This paper describes the first analytic model of the TYORP effect. Although the model rests on numerous physical and mathematical simplifications, the final analytic expression for TYORP is found to be in agreement with the results of rigorous numeric simulations to the accuracy of several tens per cent. The obtained analytic expression is used to estimate the TYORP produced by the non-flat surface of regolith, -- a contribution to TYORP that has never been considered. It is found that the contribution to TYORP arising from regolith can be comparable to the conventional TYORP produced by boulders. Then, the analytic expression is fitted with a log-normal function and used to integrate TYORP over all boulder sizes. The general trend of TYORP for multiple boulders appears qualitatively similar to the trend of one boulder, and also demonstrates a maximal TYORP at some particular rotation rate. The obtained expression for integrated TYORP may be instrumental for simulations of evolution of asteroids subject to TYORP. To conclude, the physical origin of TYORP is discussed in light of the constructed analytic model.

We also observe that, in the presence of this matter sector, the black holes will grow at a much faster rate with respect to the ordinary case. These facts can explain the observed abundance of supermassive black holes feeding high-redshift quasars. The scenario will have interesting observational consequences for dark substructures and gravitational wave production.

description: Background: Limited data exist on what young adults report as their first-ever nicotine product; some evidence suggests that they report hookah as their first product smoked. Objectives: This study reports on the first nicotine product used among undergraduates who had ever tried tobacco, and explores correlates of hookah as that first product. Methods: Participants included a convenience sample of undergraduate students (n = 1538) at four universities in upstate New York during fall 2013. Descriptive statistics assessed first nicotine product used and prevalence of current use. Logistic regression was used to examine correlates of hookah as the first nicotine product used. Results: Among the 832 students who reported ever use of any nicotine product, 25.4% reported hookah as their first product smoked; only combustible cigarettes (39.5%) were reported more frequently. Among students who ever smoked cigarettes, most reported cigarettes as their introductory product. Among students who never smoked cigarettes, nearly half reported hookah as their introductory product. Among ever nicotine users, current hookah smoking was common (34.9%), and greater than current e-cigarette (25.9%) and current combustible cigarette (26.4%) use. Never users of cigarettes, females, and non-Hispanic African Americans, had higher adjusted odds of reporting hookah as their introductory product. Conclusions: The results of this study have implications for the identification of risk factors for tobacco initiation, the assessment of tobacco use patterns and behaviors, and the tailoring of tobacco prevention initiatives among youth. Our findings suggest that broadening prevention efforts beyond a focus on combustible cigarettes may be warranted.

description: We consider a model with two real scalar fields which admits phantom domain wall solutions. We investigate the structure and evolution of these phantom domain walls in an expanding homogeneous and isotropic universe. In particular, we show that the increase of the tension of the domain walls with cosmic time, associated to the evolution of the phantom scalar field, is responsible for an additional damping term in their equations of motion. We describe the macroscopic dynamics of phantom domain walls, showing that extended phantom defects whose tension varies on a cosmological timescale cannot be the dark energy.

Algebraic Torsion in higher-dimensional contact manifolds

Subjects: subject: Symplectic Geometry (math.SG)

description: We construct examples in any odd dimension of contact manifolds with finite and non-zero algebraic torsion (in the sense of Latschev-Wendl), which are therefore tight and do not admit strong symplectic fillings. We prove that Giroux torsion implies algebraic $1$-torsion in any odd dimension, which proves a conjecture by Massot-Niederkrueger-Wendl. We construct infinitely many non-diffeomorphic examples of $5$-dimensional contact manifolds which are tight, admit no strong fillings, and do not have Giroux torsion. We obtain obstruction results for symplectic cobordisms, for which we give a proof not relying on SFT machinery. We give a tentative definition of a higher-dimensional spinal open book decomposition, based on the $3$-dimensional one of Lisi-van Horn Morris-Wendl. An appendix written in co-authorship with Richard Siefring gives a basic outline of the intersection theory for punctured holomorphic curves and hypersurfaces, which generalizes his $3$-dimensional results of Siefring to higher dimensions. From the intersection theory we obtain an application to codimension-$2$ holomorphic foliations, which we use to restrict the behaviour of holomorphic curves in our examples.

description: Rapid climate change in the Arctic may increase sexual reproduction in plants because of changes in both abiotic factors, such as temperature, and biotic factors, such as pollination. Pollination may currently limit plant reproduction in the Arctic, where cold temperatures hinder pollinator activity. To understand how warming may affect pollination and plant reproduction, we studied three plant species in western Greenland. Two species were hermaphroditic and insect-pollinated (Vaccinium uliginosum and Chamerion latifolium), and one was dioecious and insect- and wind-pollinated (Salix glauca). We measured how pollinator visitation and plant reproduction varied across three temperature zones. We also conducted pollinator exclusion and pollen supplementation experiments to measure pollinator dependence and pollen limitation. Proportion of fruit set in Vaccinium and Salix was pollen limited in every temperature zone, and Vaccinium and Chamerion depended on pollinator-mediated outcrossing for maximum reproductive success. Furthermore, higher pollinator visitation to Vaccinium in the warmer temperature zones mirrored lower pollen limitation and higher fruit set, suggesting that temperature zone indirectly influenced reproduction via changes in pollination. Taken together, our results demonstrate that both abiotic factors and pollination are important in limiting reproduction in the Arctic and that plant–pollinator interactions can mediate the response of plant reproduction to warming.
Bifurcation analysis and phase diagram of a spin-string model with buckled states

description: We analyze a one-dimensional spin-string model, in which string oscillators are linearly coupled to their two nearest neighbors and to Ising spins representing internal degrees of freedom. String-spin coupling induces a long-range ferromagnetic interaction among spins that competes with a spin-spin antiferromagnetic coupling. As a consequence, the complex phase diagram of the system exhibits different flat rippled and buckled states, with first or second order transition lines between states. The two-dimensional version of the model has a similar phase diagram, which has been recently used to explain the rippled to buckled transition observed in scanning tunnelling microscopy experiments with suspended graphene sheets. Here we describe in detail the phase diagram of the simpler one-dimensional model and phase stability using bifurcation theory. This gives additional insight into the physical mechanisms underlying the different phases and the behavior observed in experiments.

description: We study quantum phase transitions in Heisenberg antiferromagnetic chains with a staggered power-law decaying long-range interactions. Employing the density-matrix renormalization group (DMRG) algorithm and the fidelity susceptibility as the criticality measure, we establish more accurate values of quantum critical points than the results obtained from the spin-wave approximation, quantum Monte Carlo and DMRG in literatures. The deviation is especially evident for strong long-range interactions. We extend isotropic long-range interactions to the anisotropic cases and find that kaleidoscope of quantum phases emerge from the interplay of anisotropy of the long-range exchange interaction and symmetry breaking. We demonstrate nonfrustrating long-range interactions induce the true long-range order in Heisenberg antiferromagnetic chains with a continuous symmetry breaking, lifting the restrictions imposed by the Mermin-Wagner theorem.

description: A series of polyfunctionalized anthraquinonehydrazones have been prepared using azo-coupling reaction between anthraquinone-based triazenes and methylene active compounds in acetic acid without a catalyst. The structures of new synthesized compounds were confirmed by their IR, LCMS,1H and 13C NMR spectroscopic data. Some of the synthesized compounds were screened for their in vitro anticancer activity according to US NCI protocols. Biological screening data led to the identification of 1-{N’-[3-(4-hydroxyphenyl)-4-oxo-2-thioxothiazolidin-5-ylidene]hydrazino}anthraquinone 3.4 as having antitumor activity on the non-small cell lung cancer NCI-H460 (GP = 13.25%) and colon cancer HCT-116 (GP = 13.69%) cell lines.

description: El siguiente Catálogo de Mapas corresponde a un esfuerzo en el marco del proyecto “Fortalecimiento de Capacidades para la Elaboración de los PARCC y PACCC” mandatado por el Ministerio de Medio Ambiente y FAO, y ejecutado por el Centro de Derecho Ambiental (CDA) de la Universidad de Chile a través del Centro de Ciencia del Clima y la Resiliencia (CR2). En estos se representan los riesgos más importantes de cada región de Chile, utilizando la información disponible en la plataforma de Atlas de Riesgo Climático del Ministerio de Medio Ambiente (Arclim.mma.cl). Para la sistematización de los mapas, se descargaron y unificaron todas las bases de datos de ARCLIM, generando variables auxiliares para calcular los valores de riesgo y amenaza a nivel comunal. Se priorizaron las cadenas de impacto en función de variables de riesgo histórico y cambio climático, enfocándose en aquellas con valores significativos de riesgo futuro y presente. Además, se eliminaron cadenas con comportamientos erráticos o difíciles de visualizar, asegurando que los mapas reflejaran de manera clara y precisa los riesgos más relevantes para cada región del país.

description: Using embryological data from 14 mammalian orders, the hypothesis is presented that in placental mammals, epiblast cavitation and polar trophoblast loss are alternative developmental solutions to shield the central epiblast from extraembryonic signalling. It is argued that such reciprocal signalling between the edge of the epiblast and the adjoining polar trophoblast or edge of the mural trophoblast or with the amniotic ectoderm is necessary for the induction of gastrulation. This article is part of the theme issue 'Extraembryonic tissues: exploring concepts, definitions and functions across the animal kingdom'.
Causal Compatibility Inequalities Admitting Quantum Violations in the Triangle Structure

description: It has long been recognized that certain quantum correlations are incompatible with particular assumption about classical causal structure. Given a causal structure of unknown classicality, the presence of such correlations certifies the nonclassical nature of the causal structure in a device-independent fashion. In structures where all parties share a common resource, these nonclassical correlations are also known as nonlocal correlations. Any constraint satisfied by all correlations which are classically compatible with a given causal structure defines a causal compatibility criterion. Such criteria were recently derived for the Triangle structure (E. Wolfe et al., arXiv:1609.00672) in the form of polynomial inequalities, begging the question of whether any of those inequalities admit violation by quantum correlations. Numerical investigation suggests that they do not, and we further conjecture that the set of correlations admitted by the classical Triangle structure is equivalent to the set of correlations admitted by its quantum generalization whenever the three observable variables are binary. Our main contribution in this work, however, is the derivation of new causal compatibility inequalities for the Triangle structure which do admit quantum violation. This provides a robust-to-noise witness of quantum correlations in the Triangle structure. We conclude by considering the possibility of quantum resources potentially qualitatively different from those known previously.

description: We introduce a simulator of charge transport in fully-depleted, thick CCDs that include Coulomb repulsion between carriers. The calculation of this long-range interaction is highly intensive computationally, and only a few thousands of carriers can be simulated in reasonable times using regular CPUs. G-CoReCCD takes advantage of the high number of multiprocessors available in a graphical processing unit (GPU) to parallelize the operations and thus achieve a massive speedup. We can simulate the path inside the CCD bulk for up to hundreds of thousands of carriers in only a few hours using modern GPUs.
