description: The observation of primordial correlators by cosmological surveys is a very promising avenue to probe high energies and the perturbative regime of quantum gravity. Hence, it is imperative that we understand how these observables are shaped by the pillars of fundamental physics, namely unitarity, locality and symmetries. To this end, we study the three-point correlators of gravitons and scalar curvature perturbations around a quasi de Sitter spacetime. We identify a set of Bootstrap Rules that fully fix the form of these correlators in the asymptotic future, i.e. at the boundary, and make no reference to bulk time evolution. Importantly, our Boostless Bootstrap accounts for the ubiquitous (spontaneous) breaking of de Sitter boosts caused by any inflationary background. We show how all bispectra involving gravitons in single-clock, canonical inflation can be easily derived in this approach. We also derive for the first time the scalar bispectrum in the Effective Field Theory of inflation to any order in derivatives. In many cases, our derivation is computationally simpler than the corresponding explicit calculation, and makes particularly transparent the implications of locality, the choice of vacuum, and the underlying symmetries.

description: Selection of appropriate tree species is an important forest management decision that may affect sequestration of carbon (C) in soil. However, information about tree species effects on soil C stocks at the global scale remains unclear. Here, we quantitatively synthesized 850 observations from field studies that were conducted in a common garden or monoculture plantations to assess how tree species type (broadleaf vs. conifer), mycorrhizal association (arbuscular mycorrhizal (AM) vs. ectomycorrhizal (ECM)), and N-fixing ability (N-fixing vs. non-N-fixing), directly and indirectly, affect topsoil (with a median depth of 10 cm) C concentration and stock, and how such effects were influenced by environmental factors such as geographical location and climate. We found that (1) tree species type, mycorrhizal association, and N-fixing ability were all important factors affecting soil C, with lower forest floor C stocks under broadleaved (44%), AM (39%), or N-fixing (28%) trees respectively, but higher mineral soil C concentration (11%, 22%, and 156%) and stock (9%, 10%, and 6%) under broadleaved, AM, and N-fixing trees respectively; (2) tree species type, mycorrhizal association, and N-fixing ability affected forest floor C stock and mineral soil C concentration and stock directly or indirectly through impacting soil properties such as microbial biomass C and nitrogen; (3) tree species effects on mineral soil C concentration and stock were mediated by latitude, MAT, MAP, and forest stand age. These results reveal how tree species and their specific traits influence forest floor C stock and mineral soil C concentration and stock at a global scale. Insights into the underlying mechanisms of tree species effects found in our study would be useful to inform tree species selection in forest management or afforestation aiming to sequester more atmospheric C in soil for mitigation of climate change.

description: In this letter, we provide counter-examples to demonstrate that it is possible to retain second-order accuracy using Sakurai et al.'s method, even when different flux boundary conditions are imposed on multiple interfaces that do not conform to the Cartesian grid. We consider both continuous and discontinuous indicator functions in our test problems. Both indicator functions yield a similar convergence rate for the problems considered here. We also find that the order of accuracy results for some of the cases presented in Sakurai et al. are not reproducible. This is demonstrated by re-considering the same one- and two-dimensional Poisson problems solved in Sakurai et al. in this letter. The results shown in this letter demonstrate that the spatial order of accuracy of the flux-based VP approach of Sakurai et al. is between $\mathcal{O}$(1) and $\mathcal{O}$(2), and it depends on the underlying problem/model. The spatial order of accuracy cannot simply be deduced a priori based on the imposed flux values, shapes, or grid-conformity of the interfaces, as concluded in Sakurai et al. Further analysis is required to understand the spatial convergence rate of the flux-based VP method.

description: The first part of Hilbert's sixteenth problem deals with the classification of the isotopy types realizable by real plane algebraic curves of given degree $m$. For $m \geq 8$, one restricts the study to the case of the $M$-curves. For $m=9$, the classification is still wide open. We say that an $M$-curve of degree 9 has a deep nest if it has a nest of depth 3. In the present paper, we prohibit 10 isotopy types with deep nests and no outer ovals.

description: 3. RESULTS   (a) RI scaling of theropods and quadrupedal carnivorous archosaurs
 Least-squares regression of log-transformed data (table 1) indicates that theropod RI scaled to mass with an exponent of 1.546 and an intercept of ― 1.630, whereas in the quadrupedal forms RI scaled to mass with an exponent and intercept of 1.624 and ― 1.630, respectively. These slopes are significantly different (t -test, p < 0.016), and that of the quadrupedal archosaurs is closer to the value of 1.667 predicted from geometric similarity. Plotting RI against body mass (figure 2) highlights the reduction of RI at large body size in theropods, despite the apparently small difference in their scaling coefficient from that of non-dinosaurian forms. Dramatically, the 5.7 tonnes (t) Acrocanthosaurus atokensis has only 43% of the RI predicted from isometric scaling, and this diminishes to 36% in the 10 t Tyrannosaurus rex. This 10 t estimate is greater than those for other specimens of T. rex (Henderson 1999), but because mass is proportional to the cube of length, the greater length of Field Museum of Natural History specimen FMNH PR2081 (we measured it at 12.01 m) results in a substantially larger body mass. As Tyrannosaurus is almost twice the mass of the next heaviest animal, Acrocanthosaurus, T. rex could potentially act as an outlier and distort the identified scaling relationship. However, exclusion of T. rex from the regression analysis resulted in trivial changes in the slope and intercept values (to 1.545 and ― 1.629, respectively).

description: Superconductivity in the vicinity of a competing electronic order often manifests itself with a superconducting dome, centred at a presumed quantum critical point in the phase diagram. This common feature, found in many unconventional superconductors, has supported a prevalent scenario that fluctuations or partial melting of a parent order are essential for inducing or enhancing superconductivity. Here we present a contrary example, found in IrTe2 nanoflakes of which the superconducting dome is identified well inside the parent stripe charge ordering phase in the thickness-dependent phase diagram. The coexisting stripe charge order in IrTe2 nanoflakes significantly increases the out-of-plane coherence length and the coupling strength of superconductivity, in contrast to the doped bulk IrTe2. These findings clarify that the inherent instabilities of the parent stripe phaseare sufficient to induce superconductivity in IrTe2 without its complete or partial melting. Our study highlights the thickness control as an effective means to unveil intrinsic phase diagrams of correlated vdW materials.

description: The lattice $A_n^*$ is an important lattice because of its covering properties in low dimensions. Clarkson \cite{Clarkson1999:Anstar} described an algorithm to compute the nearest lattice point in $A_n^*$ that requires $O(n\log{n})$ arithmetic operations. In this paper, we describe a new algorithm. While the complexity is still $O(n\log{n})$, it is significantly simpler to describe and verify. In practice, we find that the new algorithm also runs faster.

description: A magnetically trapped atom experiences an adiabatic geometric (Berry's) phase due to changing field direction. We investigate theoretically such an Aharonov-Bohm-like geometric phase for atoms adiabatically moving inside a storage ring as demonstrated in several recent experiments. Our result shows that this phase shift is easily observable in a closed loop interference experiment, and thus the shift has to be accounted for in the proposed inertial sensing applications. The spread in phase shift due to the atom transverse distribution is quantified through numerical simulations.

description: The Klein-Gordon and Dirac equations are considered in a semi-infinite lab ($x > 0$) in the presence of background metrics $ds^2 =u^2(x) η_{μν} dx^μdx^ν$ and $ds^2=-dt^2+u^2(x)η_{ij}dx^i dx^j$ with $u(x)=e^{\pm gx}$. These metrics have non-constant scalar-curvatures. Various aspects of the solutions are studied. For the first metric with $u(x)=e^{gx}$, it is shown that the spectrums are discrete, with the ground state energy $E^2_{min}=p^2c^2 + g^2c^2\hbar^2$ for spin-0 particles. For $u(x)=e^{-gx}$, the spectrums are found to be continuous. For the second metric with $u(x)=e^{-gx}$, each particle, depends on its transverse-momentum, can have continuous or discrete spectrum. For Klein-Gordon particles, this threshold transverse-momentum is $\sqrt{3}g/2$, while for Dirac particles it is $g/2$. There is no solution for $u(x)=e^{gx}$ case. Some geometrical properties of these metrics are also discussed.

Embedding of the Racah Algebra R($\boldsymbol{n}$) and Superintegrability

description: The rank-$1$ Racah algebra $R(3)$ plays a pivotal role in the theory of superintegrable systems. It appears as the symmetry algebra of the $3$-parameter system on the $2$-sphere from which all second-order conformally flat superintegrable models in $2$D can be obtained by means of suitable limits and contractions. A higher rank generalization of $R(3)$, the so-called rank $n-2$ Racah algebra $R(n)$, has been considered recently and showed to be the symmetry algebra of the general superintegrable model on the $(n-1)$-sphere. In the present work, we show that such an algebraic structure naturally arises as embedded inside a larger quadratic algebra characterizing $n$D superintegrable models with non-central terms. This is shown both in classical and quantum mechanics through suitable (symplectic or differential) realisations of the Racah and additional generators. Among the main results, we present an explicit construction of the complete symmetry algebras for two families of $n$-dimensional maximally superintegrable models, the Smorodinsky-Winternitz system and the generalized Kepler-Coulomb system. For both families, the underlying symmetry algebras are higher-rank quadratic algebras containing the Racah algebra $R(n)$ as subalgebra. High-order algebraic relations among the generators of the full quadratic algebras are also obtained both in the classical and quantum frameworks. These results should shed new light to the further understanding of the structures of quadratic algebras in the context of superintegrable systems.

In such translation, only the compensator hypermultiplet is relevant to the SS twist, and various properties of the SS mechanism can be easily understood. Especially we show the equivalence between the SS twist and boundary constant superpotentials at the full supergravity level.

description: Mobile telecommunications are converging towards all-IP solutions. This is the case of the Long Term Evolution (LTE) technology that, having no circuit-switched bearer to support voice traffic, needs a dedicated VoIP infrastructure, which often relies on the IP Multimedia Subsystem architecture. Most telecom operators implement LTE-A, an advanced version of LTE often marketed as 4G+, which achieves data rate peaks of 300 Mbps. Yet, although such novel technology boosts the access to advanced multimedia contents and services, telco operators continue to consider the VoIP market as the major revenue for their business. In this work, the authors propose a detailed performance assessment of VoIP traffic by carrying out experimental trials across a real LTE-A environment. The experimental campaign consists of two stages. First, we characterize VoIP calls between fixed and mobile terminals, based on a dataset that includes more than 750,000 data-voice packets. We analyze quality-of-service metrics such as round-trip time (RTT) and jitter, to capture the influence of uncontrolled factors that typically appear in real-world settings. In the second stage, we further consider VoIP flows across a range of codecs, looking at the trade-offs between quality and bandwidth consumption. Moreover, we propose a statistical characterization of jitter and RTT (representing the most critical parameters), identifying the optimal approximating distribution, namely the Generalized Extreme Value (GEV). The estimation of parameters through the Maximum Likelihood criterion, leads us to reveal both the short- and long-tail behaviour for jitter and RTT, respectively.

description: Automating molecular design using deep reinforcement learning (RL) has the potential to greatly accelerate the search for novel materials. Despite recent progress on leveraging graph representations to design molecules, such methods are fundamentally limited by the lack of three-dimensional (3D) information. In light of this, we propose a novel actor-critic architecture for 3D molecular design that can generate molecular structures unattainable with previous approaches. This is achieved by exploiting the symmetries of the design process through a rotationally covariant state-action representation based on a spherical harmonics series expansion. We demonstrate the benefits of our approach on several 3D molecular design tasks, where we find that building in such symmetries significantly improves generalization and the quality of generated molecules.
Formation of Hot Planets by a combination of planet scattering, tidal circularization, and Kozai mechanism

description: We have investigated the formation of close-in extrasolar giant planets through a coupling effect of mutual scattering, Kozai mechanism, and tidal circularization, by orbital integrations. We have carried out orbital integrations of three planets with Jupiter-mass, directly including the effect of tidal circularization. We have found that in about 30% runs close-in planets are formed, which is much higher than suggested by previous studies. We have found that Kozai mechanism by outer planets is responsible for the formation of close-in planets. During the three-planet orbital crossing, the Kozai excitation is repeated and the eccentricity is often increased secularly to values close enough to unity for tidal circularization to transform the inner planet to a close-in planet. Since a moderate eccentricity can remain for the close-in planet, this mechanism may account for the observed close-in planets with moderate eccentricities and without nearby secondary planets. Since these planets also remain a broad range of orbital inclinations (even retrograde ones), the contribution of this process would be clarified by more observations of Rossiter-McLaughlin effects for transiting planets.

description: Context: Supergranulation is a pattern of the velocity field at the surface of the Sun, which has been known about for more than fifty years, however, no satisfactory explanation of its origin has been proposed. Aims: New observational constraints are therefore needed to guide theoretical approaches which hesitate between scenarios that either invoke a large-scale instability of the surface turbulent convection or a direct forcing by buoyancy. Method: Using the 14-Mpixel CALAS camera at the Pic-du-Midi observatory, we obtained a 7.5h-long sequence of high resolution images with unprecedented field size. Tracking granules, we have determined the velocity field at the Sun's surface in great detail from a scale of 2.5Mm up to 250Mm. Results: The kinetic energy density spectrum shows that supergranulation peaks at 36Mm and spans on scales ranging between 20Mm and 75Mm. The decrease of supergranular flows in the small scales is close to a $k^{-2}$-power law, steeper than the equipartition Kolmogorov one. The probability distribution function of the divergence field shows the signature of intermittency of the supergranulation and thus its turbulent nature.

description: The search for large gap quantum spin Hall (QSH) and quantum anomalous Hall (QAH) insulators is important both for fundamental and practical interests. The degenerate multi-orbitals $p_x,p_y$ in honeycomb lattice provides a paradigm for QSH state with a boosted topological gap of the first order in atomic spin-orbit coupling. By using elementary band representation, we explore the feasibility of this mechanism for QSH in general two-dimensional lattices, and find that the biparticle lattices with $C_{3v}$ or $C_{4v}$ symmetry and degenerate multi-orbitals could work. We further provide concrete tight-binding models on honeycomb, kagome and square lattices to demonstrate the desired topological physics. By introducing ferromagnetism into QSH state, we extend the mechanism to QAH state with a boosted gap. The QSH and QAH states can be achieved when Fermi level is at integer filling only for honeycomb lattice, but at certain fractional filling for other lattices. We conclude with a brief discussion on the possible material venues for such mechanism.

description: Suchomimus tenerensis.—A furcula was recovered in a partially articulated skeleton (MNN GAD513) of the spinosaurid Suchomimus tenerensis (Sereno et al., 1998). The presacral vertebral column was preserved in articulation, whereas the furcula, ribs, gastralia, girdles, and limbs were disarticulated but in close association. The furcula is V-shaped in anterior view with an intrafurcular angle of 111 ° (Fig. 1; Table 1). A dorsoventrally-flattened, tongue-shaped hypocleideum projects ventrally in the midline (Fig. 2.1). In anterior view, the hypocleideum is gently concave and displaced somewhat to the left of the midline. The absence of articular rugosities on the hypocleideum suggests that it did not contact other elements of the pectoral girdle. The central ramus has a D-shape in cross-section; anterior and posterior surfaces are convex and nearly flat, respectively (Figs. 1, 2).
The proximal half of each clavicular ramus tapers in dorsoventral width at mid length before expanding as a tongue-shaped epicleideal process (Fig. 1). With the central body held vertically, the epicleideal processes arch gently posteriorly and are marked by striations both anteriorly and posteriorly. The dorsal two-thirds of the epicleideal process is thin; the ventral one-third is thickened posteriorly to form an articular platform for the edge of the acromion.

Application software for performance monitoring
Creators: name: Chen, Rong
Publisher: name: University of British Columbia
Year: 2009

description: During recent years, control loop performance monitoring has been a topic of interest in both academic and industrial circles because the method gives non-intrusive insight into the operation of control loops. Many useful results have been obtained through research, however, their industrial applications are just starting. The main reason is the lack of good application software for implementation. In this thesis, an integrated loop monitoring software system was developed. On one hand, it provides comprehensive performance monitoring tools, including process data analysis in both time domain and frequency domain, loop oscillation detection, valve friction detection, and performance index calculation. On the other hand, it integrates all the user-system interfaces from a distributed control system (DCS) into PC networks. Two direct benefits of this approach are: first, it shields the critical DCS system from user errors, avoiding potential damage to the industrial process; second, it presents a friendly graphic user interface (GUI) to the user, making the whole system much easier to use. The whole software system was developed in an industrial environment, and preliminary evaluation has been carried out.

description: Injection from metallic electrodes serves as a main channel of charge generation in organic semiconducting devices and the quantum effect is normally regarded to be essential. We develop a dynamic approach based upon the surface hopping (SH) algorithm and classical device modeling, by which both quantum tunneling and thermionic emission of charge carrier injection at metal/organic interfaces are concurrently investigated. The injected charges from metallic electrode are observed to quickly spread onto the organic molecules following by an accumulation close to the interface induced by the built-in electric field, exhibiting a transition from delocalization to localization. We compare the Ehrenfest dynamics on mean-field level and the SH algorithm by simulating the temperature dependence of charge injection dynamics, and it is found that the former one leads to an improper result that the injection efficiency decreases with increasing temperature at room-temperature regime while SH results are credible. The relationship between injected charges and the applied bias voltage suggests it is the quantum tunneling that dominates the low-threshold injection characteristics in molecular crystals, which is further supported by the calculation results of small entropy change during the injection processes. An optimum interfacial width for charge injection efficiency at the interface is also quantified and can be utilized to understand the role of interfacial buffer layer in practical devices.

Effects of antibiotics on strains of Mycobacterium smegmatis

description: Mycobacterium smegmatis is a non-pathogenic microorganism and is classified as an acid-fast bacterium due to the accumulation of mycolic acid outside of its cell wall. Mycobacteria can survive harsh conditions and treatment with antibiotics due to their complex cell envelope. In this research, the effect of antibiotics on Mycobacterium smegmatis mc²155 and Mycobacterium smegmatis Xeno were investigated. The latter of these two is a strain of bacteria infected with the temperate N cluster mycobacteriophage Xeno. The Kirby-Bauer antibiotic sensitivity test was used to examine if the two strains are differentially susceptible to antibiotics. Prior work done in our laboratory showed that M. smegmatis mc²155 infected with various mycobacteriophage were more or less resistant to certain antibiotics. Our results show that, although there was a difference in the diameters of the zones of inhibition obtained for kanamycin, novobiocin, and penicillin, between the two strains, there was no difference when using isoniazid. A combination of isoniazid and any of the aforementioned antibiotics did not show that the drugs can act synergistically. Future studies include the use of DPH anisotropy and laurdan fluorescence test to investigate changes in membrane physical properties when M. smegmatis is cultured in the presence of antibiotics. Also, other members of the lab are attempting to create stable lysogens using the phage Juice456 (F1 subcluster) and Patt (K4 subcluster), which will be used to examine for differential antibiotic susceptibility.
Instability strips of SPB and beta Cephei stars: the effect of the updated OP opacities and of the metal mixture

description: The discovery of $β$ Cephei stars in low metallicity environments, as well as the difficulty in theoretically explaining the excitation of the pulsation modes observed in some $β$ Cephei and hybrid SPB-$β$ Cephei pulsators, suggest that the ``iron opacity bump'' provided by stellar models could be underestimated. We analyze the effect of uncertainties in the opacity computations and in the solar metal mixture, on the excitation of pulsation modes in B-type stars. We carry out a pulsational stability analysis for four grids of main-sequence models with masses between 2.5 and 12 $\rm M_\odot$ computed with OPAL and OP opacity tables and two different metal mixtures. We find that in a typical $β$ Cephei model the OP opacity is 25% larger than OPAL in the region where the driving of pulsation modes occurs. Furthermore, the difference in the Fe mass fraction between the two metal mixtures considered is of the order of 20%. The implication on the excitation of pulsation modes is non-negligible: the blue border of the SPB instability strip is displaced at higher effective temperatures, leading to a larger number of models being hybrid SPB-$β$ Cephei pulsators. Moreover, higher overtone p-modes are excited in $β$ Cephei models and unstable modes are found in a larger number of models for lower metallicities, in particular $β$ Cephei pulsations are also found in models with Z=0.01.

description: A coarse graining operation of spatially homogeneous quantum states based on an SU(1,1) Lie group structure has recently been proposed in [1] and used in [2] to compute an explicit renormalisation group flow in the context of loop quantum cosmology. In this note, we explain the group theoretical origin of this procedure and generalise previous results based on these insights. We also highlight how the group theoretical origin of these techniques implies their immediate generalisation to other Lie groups.

description: This report identifies the causes of the existing skills gap, maps the trends that will affect the raw
 materials workforce and, based on the analysis made, advances a vision for moving from industryfocused
 to future-focused skills in the EU mineral raw materials sector. This vision considers three
 priority areas:
 1. Matching worker skills to available jobs;
 2. Boost STEM training;
 3. Strengthen public-private collaboration on education and lifelong training.
 The Action Plan outlined in this document identifies four primary initiatives that should be developed
 jointly to advance the vision priority areas. To facilitate the implementation of the four initiatives, the
 Action Plan details, for each, the critical factors for success, main tasks, expected outcomes,
 performance indicators, milestones and responsibility for implementation. Lastly, a 5-step
 implementation plan, a timeframe and a cost estimation (for each initiative) provide a basis for budgeting
 (the total indicative budget of the Action Plan is 13 million Euros). The Action Plan also explores
 synergies between the initiatives and suggests a prioritisation that considers the easiness of
 implementation of the activities (assuming that less complex activities, i.e. having higher acceptance
 and few and less diversified stakeholders, are easy/simple to implement) and their expected impact
 (benefit/cost ratio). The four initiatives to be implemented are (by priority order):
 1. Development of an across-the-board approach to employability skills in the raw materials
 sector (advancing a blueprint of core employability skills) coordinated across the employer
 and educational stakeholders;
 2. Strengthen cooperation between business in the raw materials sector and higher education
 institutions and vocational education and training providers (business-led apprenticeships
 and intern programmes);
 3. Reinforce public-private collaboration to enhance intelligence on labour market needs and
 develop consistent views on the immediate and mid-term skill needs, and how much is rapid
 training enabled vs long-term education (lifelong learning pathways);
 4. Definition of the operational dimensions of quality credentials of education and training
 courses that are valued by employers in the raw materials value chain (attributes of standardbased
 credentials).

Nonchaotic Stagnant Motion in a Marginal Quasiperiodic Gradient System

Publisher: name: arXiv
Year: 2008
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: A one-dimensional dynamical system with a marginal quasiperiodic gradient is presented as a mathematical extension of a nonuniform oscillator. The system exhibits a nonchaotic stagnant motion, which is reminiscent of intermittent chaos. In fact, the density function of residence times near stagnation points obeys an inverse-square law, due to a mechanism similar to type-I intermittency. However, unlike intermittent chaos, in which the alternation between long stagnant phases and rapid moving phases occurs in a random manner, here the alternation occurs in a quasiperiodic manner. In particular, in case of a gradient with the golden ratio, the renewal of the largest residence time occurs at positions corresponding to the Fibonacci sequence. Finally, the asymptotic long-time behavior, in the form of a nested logarithm, is theoretically derived. Compared with the Pomeau-Manneville intermittency, a significant difference in the relaxation property of the long-time average of the dynamical variable is found.

description: In present paper, we describe a theoretical model of generation of harmonic emissions of type III solar radio bursts. The goal of our study is to fully take into account the most efficient physical processes participating in generation of harmonic electromagnetic emission via nonlinear coupling of Langmuir waves in randomly inhomogeneous plasma of solar wind ($l+l^{'} \rightarrow t$). We revisit the conventional mechanism of coalescence of primarily generated and back-scattered Langmuir waves in quasihomogeneous plasma. Additionally, we propose and investigate another mechanism that generates the harmonic emission only in a strongly inhomogeneous plasma: the nonlinear coupling of incident and reflected Langmuir waves inside localized regions with enhanced plasma density (clumps), in the close vicinity of the reflection point. Both mechanisms imply the presence of strong density fluctuations in plasma. We use the results of a probabilistic model of beam-plasma interaction and evaluate the efficiency of energy transfer from Langmuir waves to harmonic emission. We infer that harmonic emissions from a quasihomogeneous plasma are significantly more intense than found in previous studies. The efficiency of Langmuir waves conversion into electromagnetic harmonic emission is expected to be higher at large heliospheric distances for the mechanism operating in quasihomogeneous plasma, and at small heliocentric distances - for the one operating in inhomogeneous. The evaluation of emission intensity in quasihomogeneous plasma may also be applied for type II solar radio bursts. The radiation pattern in both cases is quadrupolar, and we show that emission from density clumps may efficiently contribute to the visibility of harmonic radio emission.
