Subjects: subject: Symplectic Geometry (math.SG)

description: We investigate the uniqueness of so-called exotic structures on certain exact symplectic manifolds by looking at how their symplectic properties change under small nonexact deformations of the symplectic form. This allows us to distinguish between two examples based on those found in \cite{maydanskiy,maydanskiyseidel}, even though their classical symplectic invariants such as symplectic cohomology vanish. We also exhibit, for any $n$, an exact symplectic manifold with $n$ distinct but exotic symplectic structures, which again cannot be distinguished by symplectic cohomology.

description: This study sought to examine the role of communicative explicitness, sex, and social class upon children's utilization of a wide variety of hesitation phenomena. Speech samples were gathered from 20 British 5-year-olds under 3 conditions of elicitation. Occurrences of 13 varieties of hesitation phenomena were tabulated for each corpus and subjected to a multivariate test for equality of mean vectors for the 2 levels of sex and social class. Although there was a significant main effect for sex, there was no significant main effect for social class and only a weak interaction of sex with social class. The verbal planning functions of the several hesitation phenomena were examined by principal components analysis and interpreted in the light of textual relations. It was found that hesitations served 3 major functions: preplanning of verbalization not yet produced, coplanning of verbalization currently being articulated, and avoidance of superfluous verbalization.

description: Recent theoretical work on the role of microscopic chaos in the dynamics and relaxation of many-body quantum systems has made several experimentally confirmed predictions about the systems of interacting nuclear spins in solids, focusing, in particular, on the shapes of spin echo responses measured by nuclear magnetic resonance (NMR). These predictions were based on the idea that the transverse nuclear spin decays evolve in a manner governed at long times by the slowest decaying eigenmode of the quantum system, analogous to a chaotic resonance in a classical system. The present paper extends the above investigations both theoretically and experimentally. On the theoretical side, the notion of chaotic eigenmodes is used to make predictions about the relationships between the long-time oscillation phase of the nuclear free induction decay (FID) and the amplitudes and phases of spin echoes. On the experimental side, the above predictions are tested for the nuclear spin decays of F-19 in CaF2 crystals and Xe-129 in frozen xenon. Good agreement between the theory and the experiment is found.

description: In this article we focus on constructing a new family of spatially anisotropic Lifshitz spacetimes with arbitrary dynamical exponent z and constant negative curvature in d+1 dimensions within the framework of the Einstein-Proca theory. The constructed metric tensor depends on both the spacetime dimensionality and the critical exponent, while the curvature scalar depends just on the number of dimensions. We also obtained a novel spectrum with negative squared mass that respects the corresponding Breitenlohner-Freedman bound. Hence these new solutions are stable and can be useful within the gravity/condensed matter theory holographic duality, since the spectrum with negative squared mass is complementary to the positive ones already known in the literature.

description: The esports industry has grown from strength to strength since the turn of the century having grown in viewership year on year and is predicted to have a larger viewership than every US professional sports league other than the NFL in 2021. As a result, more the professionalism and scrutiny of esports has grown with a number of organisations created to govern the ecosystem. The project used systematic review with thematic analysis to examine existing and past esports governance models, cases and events alongside a sports comparison. This was to help understand how effective governance has been in esports and if it could be improved to better protect stakeholders. Sports is still developing its governance with recent corruption within FIFA and the IOC but has underlined transparency, financial integrity and accountability as principles to improve its governance; these are considerations that esports should follow. Past and existing esports governing organisations have failed or lack authority in esports due to control of publisher intellectual property rights ensuring they have full control of the game titles. Global esports governing organisations have also been created frequently and promotes confusion among stakeholders over their authority and the aims for the industry. Since the creation of WESA and ESIC, it has seen improvements in governing esports with the protection of the integrity within competition and the operations of leagues and teams. However, they are missing principles laid out by sports failures leaving stakeholders worried about conflict of interest over certain decisions. This dissertation will consider the need for better governance in esports, and if it should be controlled by publishers with the support of existing organisations or the formation of national governing bodies as grassroots competition continues to grow.
Resonance eigenfunction hypothesis for chaotic systems

description: A hypothesis about the average phase-space distribution of resonance eigenfunctions in chaotic systems with escape through an opening is proposed. Eigenfunctions with decay rate $γ$ are described by a classical measure that $(i)$ is conditionally invariant with classical decay rate $γ$ and $(ii)$ is uniformly distributed on sets with the same temporal distance to the quantum resolved chaotic saddle. This explains the localization of fast-decaying resonance eigenfunctions classically. It is found to occur in the phase-space region having the largest distance to the chaotic saddle. We discuss the dependence on the decay rate $γ$ and the semiclassical limit. The hypothesis is numerically demonstrated for the standard map.

description: An experiment tested a model in which affect reflects rate of movement (velocity) toward one's behavioral goal. Participants responded to an ambiguous task and received false feedback regarding their performance. The pattern of feedback either remained fairly constant at 50% correct, went from low incidence of correct to 50% correct across trials, or went from high incidence of correct to 50% correct across trials. Self-reported mood change (from before the task to the point at which all groups received 50% correct) took the following pattern: Participants moving from frequent correct to 50% correct (low velocity) changed to less positive mood, whereas those moving from infrequent correct to 50% correct (high velocity) tended to change to more positive mood. Discussion centers on convergence between these findings and those of previous research.

description: I outline a mechanism, akin to Weibel instabilities of interpenetrating beams, in which the neighboring current sheets in a striped wind from an oblique rotator interact through a two stream-like mechanism (a Weibel instability in flatland), to create an anomalous resistivity that heats the sheets and causes the magnetic field to diffusively annihilate in the wind upstream of the termination shock. The heating has consequences for observable unpulsed emission from pulsars.

description: Dual feasible functions (DFFs) have been used to provide bounds for standard packing problems and valid inequalities for integer optimization problems. In this paper, the connection between general DFFs and a particular family of cut-generating functions is explored. We find the characterization of (restricted/strongly) maximal general DFFs and prove a 2-slope theorem for extreme general DFFs. We show that any restricted maximal general DFF can be well approximated by an extreme general DFF.

description: A game-theoretic framework for time-inconsistent stopping problems where the time-inconsistency is due to the consideration of a non-linear function of an expected reward is developed. A class of mixed strategy stopping times that allows the agents in the game to jointly choose the intensity function of a Cox process is introduced and motivated. A subgame perfect Nash equilibrium is defined. The equilibrium is characterized and other necessary and sufficient equilibrium conditions including a smooth fit result are proved. Existence and uniqueness are investigated. A mean-variance and a variance problem are studied. The state process is a general one-dimensional Itô diffusion.

description: PURPOSE: To prospectively evaluate whether ultrasonography (US)-guided vascular access can be learned and performed faster with the sonic flashlight than with conventional US and to demonstrate sonic flashlight-guided vascular access in a cadaver. MATERIALS AND METHODS: Institutional review board approval and oral and written informed consent were obtained. The sonic flashlight replaces the standard US monitor with a real-time US image that appears to float beneath the skin and is displayed where it is scanned. In studies 1 and 2, participants performed sonic flashlight-guided needle insertion tasks in vascular phantoms. In study 1, 16 participants (nine women, seven men) with no US experience performed 60 simulated vascular access trials with sonic flashlight or conventional US guidance. With analysis of variance (ANOVA) and power-curve fitting, improvement with practice rate and mean differences between techniques and tasks were examined. In study 2, 14 female nurses (mean age, 50.1 years) proficient with conventional US performed simulated vascular access trials on three tasks with the sonic flashlight and conventional US. With random assignment, half the participants used the sonic flashlight first and half used conventional US first. Mean performance with each technique and that with each task were compared by using ANOVA. In study 3, feasibility of sonic flashlight guidance for access to internal jugular and basilic veins was demonstrated in a cadaver. RESULTS: For study 1, learning rates (ie, decrease in access time over trials) did not differ for vascular access with sonic flashlight and conventional US. Overall, participants achieved faster vascular access times with sonic flashlight guidance (P < .007). In study 2, participants performed procedures faster overall with the sonic flashlight (P < .02) and found the sonic flashlight easier to use. In study 3, sonic flashlight-guided vascular access was gained in the cadaver. CONCLUSION: Learning and performance of vascular access were significantly faster with the sonic flashlight than with conventional US, and vascular access could be gained in a cadaver; the sonic flashlight is ready for clinical trials.

description: Evolution and disruption of galaxies orbiting in the gravitational field of a larger cluster galaxy are driven by three coupled mechanisms: 1) the heating due to its time dependent motion in the primary; 2) mass loss due to the tidal strain field; and 3) orbital decay. Previous work demonstrated that tidal heating is effective well inside the impulse approximation limit. Not only does the overall energy increase over previous predictions, but the work is done deep inside the secondary galaxy, e.g. at or inside the half mass radius in most cases. Here, these ideas applied to cannibalization of elliptical galaxies with fundamental-plane parameters. In summary, satellites which can fall to the center of a cluster giant by dynamical friction are evaporated by internal heating by the time they reach the center. This suggests that true merger-produced multiple nuclei giants should be rare. Specifically, secondaries with mass ratios as small as 1% on any initial orbit evaporate and those on eccentric orbits with mass ratios as small as 0.1% evolve significantly and nearly evaporate in a galaxian age. Captured satellites with mass ratios smaller than roughly 1% have insufficient time to decay to the center. After many accretion events, the model predicts that the merged system has a profile similar to that of the original primary with a weak increase in concentration.

description: Using the ergodicity principle for the expectation values of several types of observables, we investigate the thermalization process in isolated fermionic systems. These are described by the two-body random ensemble, which is a paradigmatic model to study quantum chaos and specially the dynamical transition from integrability to chaos. By means of exact diagonalizations we analyze the relevance of the eigenstate thermalization hypothesis as well as the influence of other factors, like the energy and structure of the initial state, or the dimension of the Hilbert space. We also obtain analytical expressions linking the degree of thermalization for a given observable with the so-called number of principal components for transition strengths originated at a given energy, with the dimensions of the whole Hilbert space and microcanonical energy shell, and with the correlations generated by the observable. As the strength of the residual interaction is increased an order-to-chaos transition takes place, and we show that the onset of Wigner spectral fluctuations, which is the standard signature of chaos, is not sufficient to guarantee thermalization in finite systems. When all the signatures of chaos are fulfilled, including the quasi complete delocalization of eigenfunctions, the eigenstate thermalization hypothesis is the mechanism responsible for the thermalization of certain types of observables, such as (linear combinations of) occupancies and strength function operators. Our results also suggest that fully chaotic systems will thermalize relative to most observables in the thermodynamic limit.

Material examined
Type
“ SOUTH AMERICA ” • ♂; without further locality data; MNHN (Coll Simon Nº 2795) (one unsexed specimen examined by photograph).
Records
“ Paraguay ”, without further locality data (Roewer 1928). Brazil, “ Pará ”, without further locality data (Mello-Leitão 1932).
Remarks
We tentatively propose the new combination based on the external morphology (although examination of penis morphology is imperative to be certain) of the male type (MNHN) by the following features: (1) outline of dorsal scutum gamma-type; (2) eyes poorly spaced and ocularium without depression (“Mamelon oculaire assez grand, ovale transverse, bas, légèrement granuleux.” Simon 1879); (3) areas I–III with paramedian tubercles and (4) dorsal scutum and coxa IV without yellow spots. The impossibility to examine the holotype thoroughly and the “doubtful origin” of the specimen described by Simon does not allow us to verify whether this species corresponds to another already described species. It is very difficult to conclude whether the records provided by Roewer (1928) and Mello-Leitão (1932) are correct because both localities match with those of various species of Metalibitia (Coronato & Pintoda-Rocha 2017).

description: We consider the reconstruction of a heterogeneous coefficient field in a Robin boundary condition on an inaccessible part of the boundary in a Poisson problem with an uncertain (or unknown) inhomogeneous conductivity field in the interior of the domain. To account for model errors that stem from the uncertainty in the conductivity coefficient, we treat the unknown conductivity as a nuisance parameter and carry out approximative premarginalization over it, and invert for the Robin coefficient field only. We approximate the related modelling errors via the Bayesian approximation error (BAE) approach. The uncertainty analysis presented here relies on a local linearization of the parameter-to-observable map at the maximum a posteriori (MAP) estimates, which leads to a normal (Gaussian) approximation of the parameter posterior density. To compute the MAP point we apply an inexact Newton conjugate gradient approach based on the adjoint methodology. The construction of the covariance is made tractable by invoking a low-rank approximation of the data misfit component of the Hessian. Two numerical experiments are considered: one where the prior covariance on the conductivity is isotropic, and one where the prior covariance on the conductivity is anisotropic. Results are compared to those based on standard error models, with particular emphasis on the feasibility of the posterior uncertainty estimates. We show that the BAE approach is a feasible one in the sense that the predicted posterior uncertainty is consistent with the actual estimation errors, while neglecting the related modelling error yields infeasible estimates for the Robin coefficient. In addition, we demonstrate that the BAE approach is approximately as computationally expensive (measured in the number of PDE solves) as the conventional error approach.

description: A new parametric class of semi-implicit numerical schemes for a level set advection equation on Cartesian grids is derived and analyzed. An accuracy and a stability study is provided for a linear advection equation with a variable velocity using partial Lax-Wendroff procedure and numerical von Neumann stability analysis. The obtained semi-implicit kappa-scheme is 2nd order accurate in space and time in any dimensional case when using a dimension by dimension extension of the one-dimensional scheme that is not the case for analogous fully explicit or fully implicit kappa-schemes. A further improvement is obtained by using so-called Corner Transport Upwind extension in two-dimensional case. The extended semi-implicit kappa-scheme with a specific (velocity dependent) value of kappa is 3rd order accurate in space and time for a constant advection velocity, and it is unconditional stable according to the numerical von Neumann stability analysis for the linear advection equation in general.

description: Given a parameterization $ϕ$ of a rational plane curve C, we study some invariants of C via $ϕ$. We first focus on the characterization of rational cuspidal curves, in particular we establish a relation between the discriminant of the pull-back of a line via $ϕ$, the dual curve of C and its singular points. Then, by analyzing the pull-backs of the global differential forms via $ϕ$, we prove that the (nearly) freeness of a rational curve can be tested by inspecting the Hilbert function of the kernel of a canonical map. As a by product, we also show that the global Tjurina number of a rational curve can be computed directly from one of its parameterization, without relying on the computation of an equation of C.

description: BACKGROUND: It is common for individuals with chronic disabilities to continue using the compensatory movement coordination due to entrenched habits, increased perception of task difficulty, or personality variables such as low self-efficacy or a fear of failure. Following our previous work using feedback distortion in a virtual rehabilitation environment to increase strength and range of motion, we address the use of visual feedback distortion environment to alter movement coordination patterns. METHODS: Fifty-one able-bodied subjects participated in the study. During the experiment, each subject learned to move their index finger and thumb in a particular target pattern while receiving visual feedback. Visual distortion was implemented as a magnification of the error between the thumb and/or index finger position and the desired position. The error reduction profile and the effect of distortion were analyzed by comparing the mean total absolute error and a normalized error that measured performance improvement for each subject as a proportion of the baseline error. RESULTS: The results of the study showed that (1) different coordination pattern could be trained with visual feedback and have the new pattern transferred to trials without visual feedback, (2) distorting individual finger at a time allowed different error reduction profile from the controls, and (3) overall learning was not sped up by distorting individual fingers. CONCLUSION: It is important that robotic rehabilitation incorporates multi-limb or finger coordination tasks that are important for activities of daily life in the near future. This study marks the first investigation on multi-finger coordination tasks under visual feedback manipulation.

description: Spectroscopic surveys of the Galaxy reveal that its disc stars exhibit a spread in $\mathrm{[α/Fe]}$ at fixed $\mathrm{[Fe/H]}$, manifest at some locations as a bimodality. The origin of these diverse, and possibly distinct, stellar populations in the Galactic disc is not well understood. We examine the Fe and $α$-element evolution of 133 Milky Way-like galaxies from the EAGLE simulation, to investigate the origin and diversity of their $\mathrm{[α/Fe]}$-$\mathrm{[Fe/H]}$ distributions. We find that bimodal $\mathrm{[α/Fe]}$ distributions arise in galaxies whose gas accretion histories exhibit episodes of significant infall at both early and late times, with the former fostering more intense star formation than the latter. The shorter characteristic consumption timescale of gas accreted in the earlier episode suppresses its enrichment with iron synthesised by Type Ia SNe, resulting in the formation of a high-$\mathrm{[α/Fe]}$ sequence. We find that bimodality in $\mathrm{[α/Fe]}$ similar to that seen in the Galaxy is rare, appearing in approximately 5 percent of galaxies in our sample. We posit that this is a consequence of an early gas accretion episode requiring the mass accretion history of a galaxy's dark matter halo to exhibit a phase of atypically-rapid growth at early epochs. The scarcity of EAGLE galaxies exhibiting distinct sequences in the $\mathrm{[α/Fe]}$-$\mathrm{[Fe/H]}$ plane may therefore indicate that the Milky Way's elemental abundance patterns, and its accretion history, are not representative of the broader population of $\sim L^\star$ disc galaxies.

description: Background
 The Infant and Young Child Feeding Practices are the gold standard for infants and it is crucial for young children survival. Objectives
 This study assess Knowledge, Attitude and Practices of Infant and Young Child Feeding among Nursing Mothers attending Comprehensive Health Centre, Eleyele, Ile-Ife, Osun State. Methodology
 One hundred and fifty (150) mothers were studied in a cross-sectional study design and mothers were randomly selected. Questionnaires was used to assess the socio-demographic characteristics, knowledge, attitude and practices of nursing mothers. Statistical Package for Social Science (SPSS) version 20 was used for data analysis. Chi-square analysis was used to establish
 associations.
 Results
 Results shows that, majority 85.3% of respondents were Yoruba, also there were more Christians 76.2% than other religion also 46.9% of the mothers were trader, 35.7% of the children have their birth weight <2.5Kg. In the overall knowledge, more than half 97(67.8%) had good knowledge, whereas 100(69.9%) had good attitude, while 81(56.6%) had good practices on Infant and young
 child feeding practices. There is a significant association between the overall feeding practices by
 mothers attitude, knowledge and ethnicity (P < 0.05). Conclusion
 In conclusion nursing mothers attending Comprehensive Health Centres have good knowledge, attitude on practices towards infants and young child feeding. Health workers should place more emphasis on reorienting the mothers on benefits of proper child feeding which might affect the nutritional status of their children.

Cynorta itacoaiensis: ♂, holotype (MNRJ 5059, examined), from Brazil, Amazonas, Upper Itaquaí River.
Material examined
BRAZIL • 1 ♀; Acre, Cruzeiro do Sul, proximidades do Aeroporto Internacional de Cruzeiro do Sul, rodovia AC-405; 7.595972° S, 72.766528° W; 190 m a.s.l.; 30 Oct. 2016; L.S. Carvalho leg.; CHNUFPI 2317.
Remarks
The synonymy of Gonyleptes multimaculatus with Cosmetus cordatus, established by Butler (1873), is not supported here because the former possess the following features (Fig. 13): (1) large body (> 6 mm); (2) main solid white spot mostly occupying the cephalothorax; (3) scattered white dots on abdomen, free tergites and coxa IV; (4) long and smooth legs (femur IV longer than the total length of the dorsal scutum); (5) dorsal scutum beta-type and (6) tarsal counts more numerous (6/14/8/9). All those features also show that Gonyleptes multimaculatus does not belong to the genus Libitia, better fitting the diagnosis of the recently revalidated genus Paecilaemella (see Kury & Medrano 2018). The specimens of Gonyleptes multimaculatus examined by Wood (1869) were damaged and did not allow an unambiguous diagnosis as a cosmetid, since the pedipalps are missing. Butler (1873), besides his precipitated specific synonymy, already showed the relation of the species with cosmetids. After a century, H. Soares (1970) described Cynorta itacoaensis from the Itacoaí River in upper Amazonas with a description and an illustration that entirely match those of Wood’s species. Therefore, we propose that Cynorta itacoaiensis H. Soares, 1970 is a junior synonym of Paecilaemella multimaculata (Wood, 1869) comb. nov.

A Gribov-Zwanziger type action invariant under background gauge transformations

description: We propose a Gribov-Zwanziger type action for the Landau-DeWitt gauge that preserves, for any gauge group, the invariance under background gauge transformations. At zero temperature, and to one-loop accuracy, the model can be related to the Gribov no-pole condition. We apply the model to the deconfinement transition in SU(2) and SU(3) Yang-Mills theories and compare the predictions obtained with a single or with various (color dependent) Gribov parameters that can be introduced in the action without jeopardizing its background gauge invariance. The Gribov parameters associated to color directions orthogonal to the background can become negative, while keeping the background effective potential real. In some cases, the proper analysis of the transition requires the potential to be resolved in those regions.

description: Abstract: "This work explores the use of diagrams in generating executable specifications of expert knowledge. We make the observation that experts frequently use diagrams as an efficient means of communicating detailed information. For some types of information diagrams might offer the expert an alternative to the high cost of understanding existing knowledge representation formalisms. We are interested in accomplishing three things: 1) understanding the diagramming techniques used by domain experts to encode detailed information in a restricted type of diagram called a relational diagram; 2) characterizing a set of notions that experts frequently encode in relational diagrams; 3) developing an environment that allows experts to partially construct a formal specification of problem domain knowledge by drawing relational diagrams.We describe BOS, a diagramming tool that allows domain experts to build a customized set of diagramming conventions suitable to their problem domain. Diagrams drawn with BOS generate formal specifications that reduce the need to establish the diagram's meaning through accompanying text or verbal explanation. BOS is currently able to generate frames and rules from an interesting set of relational diagrams that allow the use of spatial arrangement and connectivity to represent notions about problem domain entities, part of relations, constraints, temporal ordering, and procedural steps."
The motion of point particles in curved spacetime

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: This review is concerned with the motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime. In each of the three cases the particle produces a field that behaves as outgoing radiation in the wave zone, and therefore removes energy from the particle. In the near zone the field acts on the particle and gives rise to a self-force that prevents the particle from moving on a geodesic of the background spacetime. The field's action on the particle is difficult to calculate because of its singular nature: the field diverges at the position of the particle. But it is possible to isolate the field's singular part and show that it exerts no force on the particle. What remains after subtraction is a smooth field that is fully responsible for the self-force. The mathematical tools required to derive the equations of motion of a point scalar charge, a point electric charge, and a point mass in a specified background spacetime are developed here from scratch. The review begins with a discussion of the basic theory of bitensors. It then applies the theory to the construction of convenient coordinate systems to chart a neighbourhood of the particle's word line. It continues with a thorough discussion of Green's functions in curved spacetime. The review presents a detailed derivation of each of the three equations of motion. Because the notion of a point mass is problematic in general relativity, the review concludes with an alternative derivation of the equations of motion that applies to a small body of arbitrary internal structure.

description: We consider finite-sheeted, regular, possibly branched covering spaces of compact surfaces with boundary and the associated liftable and symmetric mapping class groups. In particular, we classify when either of these subgroups coincides with the entire mapping class group of the surface. As a consequence, we construct infinite families of non-geometric embeddings of the braid group into mapping class groups in the sense of Wajnryb. Indeed, our embeddings map standard braid generators to products of Dehn twists about curves forming chains of arbitrary length. As key tools, we use the Birman-Hilden theorem and the action of the mapping class group on a particular fundamental groupoid of the surface.

description: In this work, we study ageing behavior of aqueous laponite suspension, a model soft glassy material, in creep. We observe that viscoelastic behavior is time dependent and is strongly influenced by the deformation field; the effect is known to arise due to ageing and rejuvenation. We show that irrespective of strength of deformation field (shear stress) and age, when imposed time-scale is normalized with dominating relaxation mode of the system, universal ageing behavior is obtained demonstrating time-stress superposition; the phenomena that may be generic in variety of soft materials.
