description: Reaching the strong coupling regime of light-matter interaction has led to an impressive development in fundamental quantum physics and applications to quantum information processing. Latests advances in different quantum technologies, like superconducting circuits or semiconductor quantum wells, show that the ultrastrong coupling regime (USC) can also be achieved, where novel physical phenomena and potential computational benefits have been predicted. Nevertheless, the lack of effective decoupling mechanism in this regime has so far hindered control and measurement processes. Here, we propose a method based on parity symmetry conservation that allows for the generation and reconstruction of arbitrary states in the ultrastrong coupling regime of light-matter interactions. Our protocol requires minimal external resources by making use of the coupling between the USC system and an ancillary two-level quantum system.

description: An outstanding question lying at the core of the AdS/CFT correspondence in string theory is the holographic prescription problem for Einstein metrics, which asserts that one can slightly perturb the conformal geometry at infinity of the anti-de Sitter space and still obtain an asymptotically anti-de Sitter spacetime that satisfies the Einstein equations with a negative cosmological constant. The purpose of this paper is to address this question by providing a precise quantitative statement of the real-time holographic principle for Einstein spacetimes, to outline its proof and to discuss its physical implications.

description: We provide a complete characterization of hydrodynamic transport consistent with the second law of thermodynamics at arbitrary orders in the gradient expansion. A key ingredient in facilitating this analysis is the notion of adiabatic hydrodynamics, which enables isolation of the genuinely dissipative parts of transport. We demonstrate that most transport is adiabatic. Furthermore, of the dissipative part, only terms at the leading order in gradient expansion are constrained to be sign-definite by the second law (as has been derived before).

description: For both type 1 and type 2 diabetes mellitus, the rates have been increasing in the United States and elsewhere; rates vary widely by country, and genetic factors account for less than half of new cases. These observations suggest environmental factors cause both type 1 and type 2 diabetes. Occupational exposures have been associated with increased risk of diabetes. In addition, recent data suggest that toxic substances in the environment, other than infectious agents or exposures that stimulate an immune response, are associated with the occurrence of these diseases. We reviewed the epidemiologic data that addressed whether environmental contaminants might cause type 1 or type 2 diabetes. For type 1 diabetes, higher intake of nitrates, nitrites, and N-nitroso compounds, as well as higher serum levels of polychlorinated biphenyls have been associated with increased risk. Overall, however, the data were limited or inconsistent. With respect to type 2 diabetes, data on arsenic and 2,3,7,8-tetrachlorodibenzo-p-dioxin relative to risk were suggestive of a direct association but were inconclusive. The occupational data suggested that more data on exposure to N-nitroso compounds, arsenic, dioxins, talc, and straight oil machining fluids in relation to diabetes would be useful. Although environmental factors other than contaminants may account for the majority of type 1 and type 2 diabetes, the etiologic role of several contaminants and occupational exposures deserves further study.

description: This work describes a manufacturing system and method for the ondemand production of large metallic spare parts in a robotic welding cell using a metal-inert/aktiv-gas (MIG/MAG) welding process known as Wire-and-Arc Additive Manufacturing (WAAM). It shows how the same approach may be extended to the repair of worn metallic parts. In this case, the manufacturing system has been equipped with an optical 3D geometry acquisition device to become capable of automatically detecting the damaged regions of the parts.
The presentation also describes an algorithmic approach, which allows to locate the damaged part inside the machine's working envelope. Machine path generation may be challenging for a generic defined repair task with a non-planar base surface and for the production of spare parts, which consist of "overhanging" areas. This presentation proposes an algorithm capable of producing a valid machine program under such circumstances.

description: This paper describes the design and implementation of a minimally hazardous, environmentally friendly, and energy efficient sequential reaction sequence within a sophomore level Organic Chemistry lab course to efficiently synthesize N-phenylmaleimide precursors for a Diels–Alder reaction. Substituted N-phenylmaleimides are a class of very expensive precursors of considerable interest due to their biological properties and use as intermediates in synthesis. The synthesis described herein produces a substituted N-phenylmaleimide in two steps from maleic anhydride and a substituted aniline followed by its Diels–Alder reaction with 2,5-dimethylfuran. The experiment exposes students to the green chemistry principles of atom economy, use of safer chemicals, design for energy efficiency, waste reduction, and inherently safer chemistry for accident prevention and enables students to use 1H NMR spectroscopy to characterize the products.

Wavelet-based cross-correlation analysis of structure scaling in turbulent clouds

description: We propose a statistical tool to compare the scaling behaviour of turbulence in pairs of molecular cloud maps. Using artificial maps with well defined spatial properties, we calibrate the method and test its limitations to ultimately apply it to a set of observed maps. We develop the wavelet-based weighted cross-correlation (WWCC) method to study the relative contribution of structures of different sizes and their degree of correlation in two maps as a function of spatial scale, and the mutual displacement of structures in the molecular cloud maps. We test the WWCC for circular structures having a single prominent scale and fractal structures showing a self-similar behavior without prominent scales. Observational noise and a finite map size limit the scales where the cross-correlation coefficients and displacement vectors can be reliably measured. For fractal maps containing many structures on all scales, the limitation from the observational noise is negligible for signal-to-noise ratios >5. (abbrev). Application of the WWCC to the observed line maps of the giant molecular cloud G333 allows to add specific scale information to the results obtained earlier using the principle component analysis. It confirms the chemical and excitation similarity of $^{13}$CO and C$^{18}$O on all scales, but shows a deviation of HCN at scales of up to 7' (~7 pc). This can be interpreted as a chemical transition scale. The largest structures also show a systematic offset along the filament, probably due to a large-scale density gradient. The WWCC can compare correlated structures in different maps of molecular clouds identifying scales that represent structural changes such as chemical and phase transitions and prominent or enhanced dimensions.

description: Currently, there are metadata schemas (such as DataCite, or DDI) that can describe the concrete outputs of research, e.g., papers and datasets, but relatively little work has been done on finding a metadata schema for the research itself. The problem is that different disciplines have vastly different ways of organising research activities, for instance because of differences in funding models and mechanisms, or in requirements for approval, and thus differences in how and when research is split into discrete activities and labelled.

description: This paper provides a proof of concept for an EEG-based reconstruction of a visual image which is on a user's mind. Our approach is based on the Rapid Serial Visual Presentation (RSVP) of polygon primitives and Brain-Computer Interface (BCI) technology. The presentation of polygons that contribute to build a target image (because they match the shape and/or color of the target) trigger attention-related EEG patterns. Accordingly, these target primitives can be determined using BCI classification of Event-Related Potentials (ERPs). They are then accumulated in the display until a satisfactory reconstruction is reached. Selection steps have an average classification accuracy of $75\%$. $25\%$ of the images could be reconstructed completely, while more than $65\%$ of the available visual details could be captured on average. Most of the misclassifications were not misinterpretations of the BCI concerning users' intent; rather, users tried to select polygons that were different than what was intended by the experimenters. Open problems and alternatives to develop a practical BCI-based image reconstruction application are discussed.

description: The holographic prescription for computing entanglement entropy requires that the bulk extremal surface, whose area encodes the amount of entanglement, satisfies a homology constraint. Usually this is stated as the requirement of a (spacelike) interpolating surface that connects the region of interest and the extremal surface. We investigate to what extent this constraint is upheld by the generalized gravitational entropy argument, which relies on constructing replica symmetric q-fold covering spaces of the bulk, branched at the extremal surface. We prove (at the level of topology) that the putative extremal surface satisfies the homology constraint if and only if the corresponding branched cover can be constructed for every positive integer q. We give simple examples to show that homology can be violated if the cover exists for some values of q but not others, along with some other issues.

Adapting CETEIcean for static site building with React and Gatsby

description: The JavaScript library CETEIcean, written by Hugh Cayless and Raff Viglianti, relies on the DOM processing of web browsers and HTML5 Custom Elements to publish TEI documents as a component pluggable into any HTML structure. This makes it possible to publish and lightly transform TEI documents directly in the user’s browser, doing away with complex server-side infrastructure for TEI publishing. This lightweight approach to publishing can be valuable in a “text as data” context, where the focus of labor and algorithmic complexity may be more centered on corpus building and analysis as opposed to publication. However, CETEIcean provides a fairly bare-bones API for a fully-fledged TEI publishing solution and, without some additional considerations, TEI documents rendered with CETEIcean can be invisible to search engines. #TEI2022 - 127 This demonstration will showcase an adaptation of the CETEIcean algorithm as a plugin for the static site generator Gatsby, which relies on the popular framework React for building user interfaces (UI). The static site pages generated with Gatsby will contain embedded TEI data, making it visible to search engines. Two plugins will be shown: gatsby-transformer-ceteicean (https://www.gatsbyjs.com/plugins/gatsby-transformer-ceteicean/) prepares XML to be registered as HTML5 Custom Elements. It also allows users to apply custom transformations before and after processing if the TEI data requires it for publication (the demonstration will show an example related to addSpan elements). gatsby-theme-ceteicean (https://www.npmjs.com/package/gatsby-theme-ceteicean) implements HTML5 Custom Elements for XML publishing, particularly with TEI. It re-implements parts of CETEIcean excluding behaviors; instead, users can define React components to customize the behavior of specific TEI elements. This makes it possible to access powerful React functionalities such as state management for user interaction. The demonstration will show examples from the Scholarly Editing journal (https://scholarlyediting.org), which published TEI-based small-scale editions with these tools alongside other essay-like content.

description: We analyse a generic motility model, with the motility mechanism arising by contractile stress due to the interaction of myosin and actin. A hydrodynamic active polar gel theory is used to model the cytoplasm of a cell and is combined with a Helfrich-type model to account for membrane properties. The overall model allows to consider motility without the necessity for local adhesion. Besides a detailed numerical approach together with convergence studies for the highly nonlinear free boundary problem, we also compare the induced flow field of the motile cell with that of classical squirmer models and identify the motile cell as a puller or pusher, depending on the strength of the myosin-actin interactions.

Development, implementation, and evaluation of a multidisciplinary approach when diagnosing HIV infections in the emergency department

Publisher: name: No Publisher Supplied
Year: 2023

description: The purpose of this quality improvement paper is to evaluate the development and implementation of a multidisciplinary approach when diagnosing new HIV infections in the Emergency Department and to measure the competence and compliance of healthcare workers to this approach. Moving from a single-provider diagnosis deliverance to a multidisciplinary approach, this paper focused on the creation of a workflow supported by evidence-based practice to provide the newly diagnosed HIV patient with the necessary tools to navigate the healthcare system. Through Gemba walks for process mapping (Lean Six Sigma), education (Kaizen), and feedback from healthcare workers (through Likert-scale type surveys), the author assessed the competence and compliance of healthcare workers with a multidisciplinary deliverance process. This quality improvement project utilized a sequential, explanatory mixed method (qualitative and quantitative) to understand and characterize the processes and factors associated with the staff involved in the creation of an adequate workflow followed by proper education, to improve healthcare workers' competence and compliance in delivering HIV diagnosis to new patients coming to the ED (X2 (92, N = 93) = 8.6271, p = 0.003312). Fisher’s exact test also demonstrated statistical significance at p < 0.05. The author concluded that despite the limitations (the short duration of the project and one-site approach) and barriers (providers’ resistance and short staffing), there is a high probability that the implementation of a multidisciplinary approach improved competence and compliance of healthcare workers to create appropriate linkage-to-care as outlined by National HIV/AIDS Strategy.
EXTENDING COGNITIVE-BEHAVIORAL THEORY WITH ECOLOGICAL MOMENTARY ASSESSMENT: AN APPLICATION TO PANIC DISORDER
Creators: name: Hellberg, Samantha Noelle
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Ecological momentary assessment (EMA) can offer insight into the naturalistic course of clinical phenomena. This study used EMA to test mechanisms of panic disorder (PD) posited by cognitive-behavioral theory (CBT) across and within individuals. 38 patients with PD completed gold standard clinical interviews and 2 weeks of EMA. Preliminary validation of the EMA measure of PD was conducted. Relationships theorized by CBT were tested using both multilevel modeling (MLM) and group iterative multiple model estimation (GIMME). Aggregate and idiographic findings were compared. Averaged within-subject findings overall cohered with the CBT of PD. Subgroups were identified from individual differences in core processes. Results suggested theorized relations may vary substantially across individuals. While CBT may robustly capture mechanisms of PD for the average patient, there is a need to extend this model to address idiographic dynamics. Limitations and next steps for researchers using intensive longitudinal methods to enhance clinical theory are discussed.
Many-body microhydrodynamics of colloidal particles with active boundary layers

description: Colloidal particles with active boundary layers - regions surrounding the particles where nonequilibrium processes produce large velocity gradients - are common in many physical, chemical and biological contexts. The velocity or stress at the edge of the boundary layer determines the exterior fluid flow and, hence, the many-body interparticle hydrodynamic interaction. Here, we present a method to compute the many-body hydrodynamic interaction between $N$ spherical active particles induced by their exterior microhydrodynamic flow. First, we use a boundary integral representation of the Stokes equation to eliminate bulk fluid degrees of freedom. Then, we expand the boundary velocities and tractions of the integral representation in an infinite-dimensional basis of tensorial spherical harmonics and, on enforcing boundary conditions in a weak sense on the surface of each particle, obtain a system of linear algebraic equations for the unknown expansion coefficients. The truncation of the infinite series, fixed by the degree of accuracy required, yields a finite linear system that can be solved accurately and efficiently by iterative methods. The solution linearly relates the unknown rigid body motion to the known values of the expansion coefficients, motivating the introduction of propulsion matrices. These matrices completely characterize hydrodynamic interactions in active suspensions just as mobility matrices completely characterize hydrodynamic interactions in passive suspensions. The reduction in the dimensionality of the problem, from a three-dimensional partial differential equation to a two-dimensional integral equation, allows for dynamic simulations of hundreds of thousands of active particles on multi-core computational architectures.

Implications of turbulence for jets in core-collapse supernova explosions

Year: 2014
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We show that turbulence in core collapse supernovae (CCSNe) which has been shown recently to ease shock revival might also lead to the formation of intermittent thick accretion disks, or accretion belts, around the newly born neutron star (NS). The accretion morphology is such that two low density funnels are formed along the polar directions. The disks then are likely to launch jets with a varying axis direction, i.e., jittering-jets, through the two opposite funnels. The energy contribution of jets in this jittering jets mechanism might result in an explosion energy of E>10^51erg, even without reviving the stalled shock. We strengthen the jittering jets mechanism as a possible explosion mechanism of CCSNe.

description: The thermodynamics of the Universe is restudied by requiring its compatibility with the holographic-style gravitational equations which govern the dynamics of both the cosmological apparent horizon and the entire Universe, and possible solutions are proposed to the existent confusions regarding the apparent-horizon temperature and the cosmic entropy evolution. We start from the generic Lambda Cold Dark Matter ($Λ$CDM) cosmology of general relativity (GR) to establish a framework for the gravitational thermodynamics. The Cai-Kim Clausius equation for the isochoric process of an instantaneous apparent horizon indicates that, the Universe and its horizon entropies encode the \emph{positive heat out} thermodynamic sign convention, which encourages us to adjust the traditional positive-heat-in Gibbs equation into the positive-heat-out version $dE_m=-T_mdS_m-P_mdV$. It turns out that the standard and the generalized second laws (GSLs) of nondecreasing entropies are always respected by the event-horizon system as long as the expanding Universe is dominated by nonexotic matter $-1\leq w_m\leq 1$, while for the apparent-horizon simple open system the two second laws hold if $-1\leq w_m

description: Epidemic outbreaks of new pathogens, or known pathogens in new populations, cause a great deal of fear because they are hard to predict. For theoretical models of disease spreading, on the other hand, quantities characterizing the outbreak converge to deterministic functions of time. Our goal in this paper is to shed some light on this apparent discrepancy. We measure the diversity of (and, thus, the predictability of) outbreak sizes and extinction times as functions of time given different scenarios of the amount of information available. Under the assumption of perfect information -- i.e., knowing the state of each individual with respect to the disease -- the predictability decreases exponentially, or faster, with time. The decay is slowest for intermediate values of the per-contact transmission probability. With a weaker assumption on the information available, assuming that we know only the fraction of currently infectious, recovered, or susceptible individuals, the predictability also decreases exponentially most of the time. There are, however, some peculiar regions in this scenario where the predictability decreases. In other words, to predict its final size with a given accuracy, we would need increasingly more information about the outbreak.

description: Spin-orbit interaction in Sr$_2$IrO$_4$ leads to the realization of the $J_{\mathrm{eff}}$ = 1/2 state and also induces an insulating behavior. Using large-shift Raman spectroscopy, we found two high-energy excitations of the d-shell multipletat at 690 meV and 680 meV with $A_{1g}$ and $B_{1g}$ symmetry respectively. As temperature decreases, the $A_{1g}$ and $B_{1g}$ peaks narrow, and the $A_{1g}$ peak shifts to higher energy while the energy of the $B_{1g}$ peak remains the same. When 25$\%$ of Ir is substituted with Rh the $A_{1g}$ peak softens by 10$\%$ but the $B_{1g}$ peak does not. We show that both pseudospin-flip and non-pseudosin-flip dd electronic transitions are Raman active, but only the latter are observed.
Multidimensional Social Support and Parenting among Black Fathers: A Profile-Oriented Approach
Creators: name: McBride, Margarett
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2021

description: Though the literature has gained more understanding of Black men and their support, little is known about who Black fathers lean on for support and how these support systems impact their parenting practices and beliefs. This investigation utilizes a profile-oriented approach to understand patterns of Black father general and parental support systems and how these systems impact parenting beliefs and involvement in the face of parental stress. Derived from the Representations of Fatherhood: Roles, Awareness, and MEaning (REFRAME) study, we utilized a national sample of 759 Black fathers with children between the ages of 8 and 17. Results indicate that there are 10 social support profiles for Black fathers and that these profiles vary in their levels of parenting stress, beliefs, and involvement. In general, parenting stress negatively impacts parenting beliefs, however, this relationship varies based on social support profile membership. Further implications for programming and intervention research are discussed.

description: The impossibility of superluminal communication is a fundamental principle of physics. Here we show that this principle underpins the performance of several fundamental tasks in quantum information processing and quantum metrology. In particular, we derive tight no-signaling bounds for probabilistic cloning and super-replication that coincide with the corresponding optimal achievable fidelities and rates known. In the context of quantum metrology, we derive the Heisenberg limit from the no-signaling principle for certain scenarios including reference frame alignment and maximum likelihood state estimation. We elaborate on the equivalence of assymptotic phase-covariant cloning and phase estimation for different figures of merit.

A modeling approach to investigating the impact of member heterogeneity on group performance
Creators: name: Dykstra, Nicole
Publisher: name: No Publisher Supplied
Year: 2023

description: Group membership allows individuals the potential to coordinate their behavior in order to maximize group performance. However, the group’s performance depends on its individual members correctly accomplishing the tasks that are most relevant to its goal, and differences among individuals contribute to their ability to complete tasks efficiently or correctly. This dissertation is broken up into three major objectives, with the main goal of investigating the impact of group-member heterogeneity on the group’s overall performance, using a modeling approach. The first objective is to decouple and measure individually the contributions of division of labor and division of skills (worker expertise) to workers’ task completion as a measure of collective group output. We consider group size, task diversity, varying degrees of division of labor and probabilities of worker expertise, and include as a model parameter the potential cost of switching from one task to another. We also include as an introductory chapter to this objective a review of the origin of division of labor. The second objective is to measure the impact on group performance of matching workers with specific skill expertise with available tasks when switching between tasks incurs a temporary loss of productivity. Taking the perspective of the group, we aim to (a) identify the conditions in which a mechanism to match workers’ skills with the tasks present increased worker performance and to (b) quantify that increase. The third objective is to measure the impact of group members’ perception of the expertise of fellow players on group performance in a binary choice game and to investigate the consequences of not just a single choice, but a series of them. The major results of this dissertation include: a review of the potential evolutionary and self-organizational explanations for the origin of division of labor; that colony efficiency is modulated by the presence of a cost to switching among tasks, and that this cost may promote the development of division of labor, but not worker expertise except under narrow circumstances; that the greatest improvements to worker performance with the implementation of a matching mechanism occurred when task diversity is high, and that large groups benefit from the matching mechanism slightly more than small groups; and that group performance is modulated by member expertise and the sharing of information about earlier votes, especially in groups of players with the lowest skill but in which expert players were given voting priority, particularly in the more difficult games.

description: The properties of the observed Higgs boson with mass around 125 GeV can be affected in a variety of ways by new physics beyond the Standard Model (SM). The wealth of experimental results, targeting the different combinations for the production and decay of a Higgs boson, makes it a non-trivial task to assess the compatibility of a non-SM-like Higgs boson with all available results. In this paper we present Lilith, a new public tool for constraining new physics from signal strength measurements performed at the LHC and the Tevatron. Lilith is a Python library that can also be used in C and C++/ROOT programs. The Higgs likelihood is based on experimental results stored in an easily extensible XML database, and is evaluated from the user input, given in XML format in terms of reduced couplings or signal strengths. The results of Lilith can be used to constrain a wide class of new physics scenarios.

description: Based on the universality of the entropy-area relation of a black hole, and the fact that the generalized uncertainty principle (GUP) adds a logarithmic correction term to the entropy in accordance with most approaches to quantum gravity, we argue that the GUP-corrected entropy-area relation is universal for all black objects. This correction to the entropy produces corrections to the thermodynamics. We explicitly calculate these corrections for three types of black holes: Reissner--Nordström, Kerr, and charged AdS black holes, in addition to spinning black rings. In all cases we find that they produce a remnant. Even though the GUP-corrected entropy-area relation produces the logarithmic term in the series expansion, we need to use the full form of the GUP-corrected entropy-area relation to get remnants for these black holes.

description: Via an appropriate field redefinition of the fermions, we find a set of conditions under which light cone gauge fixed world sheet theories of strings on two different backgrounds are related by a double Wick rotation. These conditions take the form of a set of transformation laws for the background fields, complementing a set of transformation laws for the metric and B field we found previously with a set for the dilaton and RR fields, and are compatible with the supergravity equations of motion. Our results prove that at least to second order in fermions, the AdS_5 x S^5 mirror model which plays an important role in the field of integrability in AdS/CFT, represents a string on `mirror AdS_5 x S^5', the background that follows from our transformations. We discuss analogous solutions for AdS_3 x S^3 x T^4 and AdS_2 x S^2 x T^6. The main ingredient in our derivation is the light cone gauge fixed action for a string on an (almost) completely generic background, which we explicitly derive to second order in fermions.

Ecstasy in real life
Creators: name: Ortiz, Devonaire
Publisher: name: No Publisher Supplied
Year: 2023

description: Ecstasy in Real Life is a project of desire—an interrogation of wanting and needing, and where the two become inseparable. My intention as an artist has always been to celebrate delight and find ways to express the wonder of my little world: of my people, of movement, of the hood, of queer life, and all that they bring. In doing so, this collection became one of questioning our joys just as much as it seeks to put them on display. Where does release end and escapism begin? How far will we go for euphoria? These poems started as an inventory of earthly desires and evolved into a dreamscape— images of the little world ruptured and rebuilt. Equal parts confessional, playground, and coro-in-verse, the language of this work is driven by an endless sense of yearning and the music of my life. It draws inspiration from the poetics of Lauryn Hill, Jay-Z, Summer Walker, Diana Ross, Lana Del Rey, Mariah Carey, Kelela, Lady Gaga, Janet Jackson, Donna Summer, Nicki Minaj, and of course, Lykke Li, who says it perfectly: couldn’t possibly tell you how I mean, but I can dance, dance, dance.

Survey

description: This 2022 online survey was conducted and evaluated by CODEX+ WP2.2, over the course from September to November. The "FAIR Guiding Principles for scientific data management and stewardship" were published in 2016. They describe various requirements for research data regarding their findability, accessibility, interoperability and reusability. In addition to general recommendations, the FAIR principles also include a number of concrete measures for the so-called "FAIRness" of research data. More at: GOFAIR - FAIR Principles General questions about about the four FAIR categories (Findability, Accessibility, Interoperability, Reusability) will be asked over 20 question. The aim of our survey is to find out to what extent the FAIR principles are already applied in the different projects across the NUM-Netzwerk (Netzwerk Universitätsmedizin). We do so in order to identify any further steps of how our work can improve the FAIRness of the projects. By the term "data" we refer to the data "processed or existing" in the projects in general (e.g. software or documentation). In the following, the term 'dataset' means: A dataset is a collection of related, discrete data that can be accessed individually or in combination, or that is managed as a whole.
On type-preserving representations of the four-punctured sphere group

description: We give counterexamples to a question of Bowditch that if a non-elementary type-preserving representation $ρ:π_1(Σ_{g,n})\rightarrow PSL(2;\mathbb R)$ of a punctured surface group sends every non-peripheral simple closed curve to a hyperbolic element, then must $ρ$ be Fuchsian. The counterexamples come from relative Euler class $\pm1$ representations of the four-punctured sphere group. We also show that the mapping class group action on each non-extremal component of the character space of type-preserving representations of the four-punctured sphere group is ergodic, which confirms a conjecture of Goldman for this case. The main tool we use is Kashaev-Penner's lengths coordinates of the decorated character spaces.

Low frequency QPOs and possible change in the accretion geometry during the outbursts of Aquila X$-$1

description: We have studied the evolution of the Low Frequency Quasi-Periodic Oscillations (LFQPOs) during the rising phase of seven outbursts of the neutron star Soft X-ray Transient (SXT) Aql X$-$1 observed with the \textit{Rossi X-ray Timing Explorer (RXTE)}. The frequency correlation between the low frequency break and the LFQPO sampled on the time scale of $\sim$2 days was seen. Except for the peculiar 2001 outburst, the frequency of the LFQPOs increased with time before the hard-to-soft state transition up to a maximum $ν_{max}$ at $\sim$31 Hz, a factor of $\sim$5 higher than those seen in black hole transients such as GX 339$-$4, making the maximum QPO frequency a likely indicator of the mass of the central compact object. The characteristic frequencies increased by around ten percent per day in the early rising phase and accelerated to nearly one hundred percent per day since $\sim$2 days before the hard-to-soft state transition. We examined the dependence of the frequency $ν_{LF}$ on the source flux $f$ and found an anti-correlation between the maximum frequency of the LFQPOs and the corresponding X-ray luminosity of the hard-to-soft transition (or outburst peak luminosity) among the outbursts. We suggest that X-ray evaporation process can not be the only mechanism that drives the variation of the inner disk radius if either of the twin kHz QPO corresponds to the Keplerian frequency at the truncation radius.
