description: We use a particular machine learning approach, called the genetic algorithms (GA), in order to place constraints on deviations from general relativity (GR) via a possible evolution of Newton's constant $μ\equiv G_\mathrm{eff}/G_\mathrm{N}$ and of the dark energy anisotropic stress $η$, both defined to be equal to one in GR. Specifically, we use a plethora of background and linear-order perturbations data, such as type Ia supernovae, baryon acoustic oscillations, cosmic chronometers, redshift space distortions and $E_g$ data. We find that although the GA is affected by the lower quality of the currently available data, especially from the $E_g$ data, the reconstruction of Newton's constant is consistent with a constant value within the errors. On the other hand, the anisotropic stress deviates strongly from unity due to the sparsity and the systematics of the $E_g$ data. Finally, we also create synthetic data based on a next-generation survey and forecast the limits of any possible detection of deviations from GR. In particular, we use two fiducial models: one based on the cosmological constant $Λ$CDM model and another on a model with an evolving Newton's constant, dubbed $μ$CDM. We find that the GA reconstructions of $μ(z)$ and $η(z)$ can be constrained to within a few percent of the fiducial models and in the case of the $μ$CDM mocks, they can also provide a strong detection of several $σ$s, thus demonstrating the utility of the GA reconstruction approach.

description: We examine the distribution and interpretation of post-copular noun phrases in French when they appear with and without an indefinite article (Marie est (une) physicienne). We propose that the alternation is due to the fact that the indefinite article marks saturation of an NP-internal argument slot, and show that because of this, post-copular indefinite NPs are usually but not always existentially quantified, while bare NPs are predicative. This theory leads to new perspectives both on cross-linguistic marking of post-copular NPs and on the treatment of the indefinite article.

description: The one-dimensional elephant random walk is a typical model of discrete-time random walk with step-reinforcement, and is introduced by Schütz and Trimper (2004). It has a parameter $α\in (-1,1)$: The case $α=0$ corresponds to the simple symmetric random walk, and when $α>0$ (resp. $α<0$), the mean displacement of the walker at time $n$ grows (resp. vanishes) like $n^α$. The walk admits a phase transition at $α=1/2$ from the diffusive behavior to the superdiffusive behavior. In this paper, we study the rate of the moment convergence in the central limit theorem for the position of the walker when $-1 < α\leq 1/2$. We find a crossover phenomenon in the rate of convergence of the $2m$-th moments with $m=2,3,\ldots$ inside the diffusive regime $-1<α<1/2$.

description: MRChem is a code for molecular electronic structure calculations, based on a multiwavelet adaptive basis representation. We provide a description of our implementation strategy and several benchmark calculations. Systems comprising more than a thousand orbitals are investigated at the HF level of theory, with an emphasis on scaling properties. With our design, terms which formally scale quadratically with the system size, in effect have a better scaling because of the implicit screening introduced by the inherent adaptivity of the method: all operations are performed to the requested precision, which serves the dual purpose of minimizing the computational cost and controlling the final error precisely. Comparisons with traditional Gaussian-type orbitals based software, show that MRChem can be competitive with respect to performance.

description: A careful study of naming constructions is essential for the understanding of the syntax and semantics of proper names. Cross-linguistic analysis of verbs of naming shows that they take a small clause complement and therefore argues that a proper name is essentially a nominal predicate, whose contents mentions the name itself. The indexicality of proper names in argument positions can be compositionally derived from their independently motivated internal complexity.

description: We present a simple extension of the Standard Model with three right-handed neutrinos in a SUSY framework, with an additional U(1$)_\text{F}$ abelian flavor symmetry with a non standard leptonic charge $L_e-L_μ-L_τ$ for lepton doublets and arbitrary right-handed charges. We show that the model is able to reproduce the experimental values of the mixing angles of the PMNS matrix and of the $r=Δm_\text{sun}^2/Δm_\text{atm}^2$ ratio, with only a moderate fine tuning of the Lagrangian free parameters. The baryon asymmetry of the Universe is generated via thermal leptogenesis through CP-violating decays of the heavy right-handed neutrinos. We present a detailed numerical solution of the relevant Boltzmann equation accounting for the impact of the distribution of the asymmetry in the various lepton flavors.

Year: 2019

description: In this paper we argue that reflexive psychological verbs in Spanish (SRPVs), such as aburrirse ‘bore-REFL’ constitute a special subclass of stative predicate which we term BOUNDED STATE PREDICATES. Bounded state predicates entail that the onset of the state they denote falls within the reference time for the predicate. The analysis not only accounts for subtle differences between SRPVs and related estar+participle expressions but also lays the groundwork for explaining the otherwise puzzling fact that SRPVs are translated into English with phrases involving get in some cases and be in others.

description: Presentation for: Workshop on Open Citations and Open Scholarly Metadata 2022 (online), October 5 2022 Abstract:
 Research funders spend considerable efforts collecting information on outcomes of the research they fund. To help funders track publication output associated with their funding, Crossref initiated FundRef in 2013, enabling publishers to register funding information using persistent identifiers. However, it is hard to assess the coverage of funder metadata because it is unknown how many articles are the result of funded research and therefore should include funder metadata. We looked at 5,004 publications reported by researchers to be the result of funding by a specific funding agency: the Dutch Research Council NWO. Only 67% of these articles contain funding information in Crossref, with a subset acknowledging NWO as funder name and/or Funder IDs linked to NWO (53% and 45%, respectively). Web of Science (WoS), Scopus and Dimensions are all able to infer additional funding information from funding statements in the full text of the articles. Funding information in Lens largely corresponds to that in Crossref, with some additional funding information likely taken from PubMed. We observe interesting differences between publishers in the coverage and completeness of funding metadata in Crossref compared to proprietary databases, highlighting potential to increase the quality of open metadata on funding.

De Se Reductionism Takes on Monsters

Year: 2019

description: Chierchia (1989) and others have used the contrast between George hopes that he will win and Georges hopes to win in mistaken-self-identity scenarios, to argue for dedicated de se LFs. The argument, further strengthened by evidence of shiftable indexicals, appears applicable against any reductionist account that sees de se as merely a particular subtype of de re. My Acquaintance Resolution framework is an attempt at such a reduction, and this paper seeks to extend that theory with a logical principle of introspection for belief, to account for the data within a unified treatment of de re and de se.

Measuring the degree of unitarity for any quantum process

Year: 2014

description: Quantum processes can be divided into two categories: unitary and non-unitary ones. For a given quantum process, we can define a \textit{degree of the unitarity (DU)} of this process to be the fidelity between it and its closest unitary one. The DU, as an intrinsic property of a given quantum process, is able to quantify the distance between the process and the group of unitary ones, and is closely related to the noise of this quantum process. We derive analytical results of DU for qubit unital channels, and obtain the lower and upper bounds in general. The lower bound is tight for most of quantum processes, and is particularly tight when the corresponding DU is sufficiently large. The upper bound is found to be an indicator for the tightness of the lower bound. Moreover, we study the distribution of DU in random quantum processes with different environments. In particular, The relationship between the DU of any quantum process and the non-markovian behavior of it is also addressed.

description: We present an updated sample of blue horizontal-branch (BHB) stars selected from the photometric and spectroscopic data from Sloan Digital Sky Survey and its associated project Sloan Extension for Galactic Understanding and Exploration (SEGUE). With this data, we selected candidates for A-type stars in the color-color space and then a mixture modeling technique was implemented in order to distinguish between BHB and main-sequence/blue-straggler stars based on their surface gravity values ($\log \rm{g}$) estimated by the SEGUE Stellar Parameter Pipeline. Our robust approach allows us to attribute individual probabilities of each star truly being in the BHB stage. Hence, our method is advantageous in comparison to previous SEGUE BHB selections that adopted simple $\log \rm{g}$ cuts. We also revisit the color-magnitude relation for these stars and propose two calibrations, based on updated distances for Galactic globular clusters, to estimate absolute magnitudes with $(g-r)_0$ and $(u-r)_0$ colors.

Attitudes Toward Degrees

description: Degree modifiers of the type exemplified in the sentence “She was frustratingly late” are analyzed. These modifiers, which indicate that a propositional attitude – here frustration – holds with respect to the degree associated with the predicate – here lateness, are shown to have certain monotonicity entailments which are absent from simple adverbial attitude reports such as “Frustratingly, she was 10 minutes late.” These entailments account for an interesting puzzle concerning the semantics of the degree modifiers which arises when standard analyses of attitude predicates are combined with standard accounts of degree modification.

description: We study some observational signatures of nonlinearities of the electromagnetic field. First to all we show the vital role played by nonlinearities in triggering a material behavior of the vacuum with $(\varepsilon > 0, μ<0)$, which corresponds to a ferrimagnetic material. Secondly, the permittivity and susceptibility induced by nonlinearities are considered in order to obtain the refractive index via the dispersion relation for logarithmic electrodynamics. Finally, we consider the electromagnetic radiation produced by a moving charged particle interacting with a medium characterized by nonlinearities of the electromagnetic field. To this end we consider logarithmic electrodynamics. The result shows that the radiation is driven by the medium through which the particle travels like the one that happens in the Cherenkov effect.

description: In dieser qualitativen Forschungsarbeit befragten die Autoren Mischa Bucher und Yannik Fasser fünf Careleaver. Die Arbeit ist der Frage gewidmet, wie peergestützte Ansätze in einem Careleaver-Netzwerk angewendet werden und welche Erfahrungen von Careleaver damit gesammelt werden. Careleaver sind junge Erwachsene, welche sich im Übertritt in die Eigenständigkeit befinden und einen Teil ihres Lebens in einem stationären Setting oder einer Pflegefamilie verbracht haben. Die Careleaver-Netzwerke bieten den Careleaver Möglichkeiten, sich mit Gleichgesinnten auszutauschen, sich weiterzubilden oder sich auf gesellschaftlicher, politischer oder institutioneller Ebene aktiv für die Leaving-Care-Thematik einzusetzen. Einleitend wird in dieser Arbeit in zwei Theoriekapiteln auf die Careleaver und den Peer-Ansatz eingegangen. Die beiden Kapitel werden abgerundet mit dem Beizug zweier Theoretiker der Sozialen Arbeit, Lothar Bönisch und Michael Winkler, damit ein theoretischer Bezug hergestellt wird. Die Grundsätze der qualitativen Forschung werden im Forschungsdesign vorgestellt. Die fünf Interviews wurden mit der Methode des Leitfadeninterviews geführt und transkribiert sowie nach der qualitativen Inhaltsanalyse nach Philipp Mayring ausgewertet. In der Forschung zeigte sich, dass vor allem die Kommunikation mit Gleichgesinnten im Netzwerk von den Careleaver geschätzt wird und dass peergestützte Ansätze für den Übertritt in die Eigenständigkeit unterstützend wirken können.

A Semantic Analysis of the Korean Plural Marker 'Tul'
Creators: name: Joh, Yoon-Kyoung
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: I argue that Extrinsic Plural Marker tul in Korean has two semantic components, distributivity and maximality, that operate on the predicate that tul attaches to. In this paper, the universal quantificational force associated with the semantic effects of EPM-tul will be accounted for, relying on a distributivity operator and a focussensitive operator. The good-fitting requirement on the Cover variable of the distributivity operator explains the maximizing effect of the predicate marked with tul while the focus-sensitive operator captures the fact that different positions of EPM-tul generate different distributive relations.

description: Full 3D inversion of time-domain Airborne ElectroMagnetic (AEM) data requires specialists' expertise and a tremendous amount of computational resources, not readily available to everyone. Consequently, quasi-2D/3D inversion methods are prevailing, using a much faster but approximate (1D) forward model. We propose an appraisal tool that indicates zones in the inversion model that are not in agreement with the multidimensional data and therefore, should not be interpreted quantitatively. The image appraisal relies on multidimensional forward modelling to compute a so-called normalized gradient. Large values in that gradient indicate model parameters that do not fit the true multidimensionality of the observed data well and should not be interpreted quantitatively. An alternative approach is proposed to account for imperfect forward modelling, such that the appraisal tool is computationally inexpensive. The method is demonstrated on an AEM survey in a salinization context, revealing possible problematic zones in the estimated fresh-saltwater interface.

description: We explore nonrelativistic limits of $\mathcal{N}=1$ quiver gauge theories in 5d. The stringy counterpart of these SCFTs is characterised by torsional string Newton-Cartan (TSNC) sigma models those are defined over non-Lorentzian manifolds. We further show that under transverse T-duality, these TSNC sigma models are mapped into another new class of nonrelativistic sigma models those are defined over a T-dual TSNC background. Considering nonrelativistic limits of various field theory observables in a holographic set up, we further estimate corresponding entities in the TSNC limit of $ \mathcal{N}=1 $ quivers. We carry out a parallel analysis on holomorphic functions and the associated pole structures in the nonrelativistic limit of ($ p ,q $) five brane webs. In particular, we investigate the generic structure of various loop operators in a nonrelativistic set up and explore their properties under S-duality. Finally, we comment on the large $ c $ limit of RR fields and discuss the associated S-duality transformation rules in the nonrelativistic limit of $ \mathcal{N}=1 $ quivers.

In this study genetic and proteomic variation of Labeo rohita determined by functional genomics and proteomics through computational biology and bioinformatics. This is the advance level of consequent study which carried over the whole genome sequencing shotgun analysis done by the students of MS. Fisheries & Limnology Session 2017-2018 previous year. In chromosome level assembly of L. rohita total number of bases of the genome found is 1,159,574,983 . No. of sequence in my study is 2401 which indicates less fragmented better genome than other reference sequence. N50 is 35.5 mbp2, L50 is smallest in my study 9, which is better because of having large sized scaffolds. Among 47,568 genes found in my study up to chromosome level, majority of those are placed in chromosome. Approximately 1010 annotated genes are protein coding and directly or indirectly responsible for muscle growth of L. rohita from Halda River. According to the refseq BAU-BD-2019 approximately 82 unique genes are found in L. rohita from Halda River. 29.27% of those genes are unplaced; 24 genes. Among 82 genes, 58 (70.73%) genes are placed in chromosome. Max. number of unique muscle genes lies in chr. 2 indicating high degree of polymorphism and mutations while no uniqueness in chr. 10, chr. 13, chr. 22 & chr. 23 indicates less polymorphism and mutations in those regions. This study carried out the divergence, unique genetic features of one of the most important common carp ‘Rohu’ from Halda River.

description: We present an image segmentation framework based on a fast feature matching algorithm designed to leverage powerful pretrained vision foundation models. Our framework is embedded into a computer vision annotation tool which enables an interactive image segmentation workflow for precise segmentation guided by visual prompting. Users begin by uploading an image and marking objects of interest with scribbles directly on the interface. These scribbles serve as annotations to guide the segmentation process. Upon initiating segmentation, the system leverages pretrained models and our efficient matching algorithms to generate segmentation masks in real-time. Users can then review the initial results and iteratively refine them by adding or deleting scribbles as needed. This interactive workflow enables rapid feedback loops, facilitating the iterative refinement of annotations tailored to the requirements of the particular visual domain at hand. By customizing annotations iteratively, users can swiftly optimize segmentation accuracy, resulting in a comprehensive, data-driven solution for achieving precise segmentation across diverse technical visual domains.
Togetherness

description: This paper investigates the notion of ‘togetherness’ expressed by adverbials like together in English or ensemble in French. We show that the natural division between the main uses of these adverbials is aspectual: whereas achievements impose no significant restrictions, non-achievements demand that the eventualities that are grouped ‘together’ be causally controlled or coordinated. In particular, contrary to what is frequently assumed in the literature, it is not sufficient that they occupy the same spatio-temporal location. This leads us to propose a new picture of togetherness, which accounts for the intuitions of ‘grouping’ (Lasersohn) or ‘integration’ (Moltmann) but puts them in a different perspective.

description: In this paper we analyze the expected time complexity of the auction algorithm for the matching problem on random bipartite graphs. We prove that the expected time complexity of the auction algorithm for bipartite matching is $O\left(\frac{N\log^2(N)}{\log\left(Np\right)}\right)$ on sequential machines. This is equivalent to other augmenting path algorithms such as the HK algorithm. Furthermore, we show that the algorithm can be implemented on parallel machines with $O(\log(N))$ processors and shared memory with an expected time complexity of $O(N\log(N))$.

description: In the present paper we investigate thermal fluctuation corrections to the vacuum energy at zero temperature of a conformally coupled massless scalar field whose modes propagate in the Einstein universe with a spherical boundary, characterized by both Dirichlet and Neumann boundary conditions. Thus, we generalize the results found in literature in this scenario, which has considered only the vacuum energy at zero temperature. To do this, we use the generalized zeta function method plus Abel-Plana formula and calculate the renormalized Casimir free energy as well as other thermodynamics quantities, namely, internal energy and entropy. For each one of them we also investigate the limits of high and low temperatures. At high temperatures we found that the renormalized Casimir free energy presents classical contributions, along with a logarithmic term. Also in this limit, the internal energy presents a classical contribution and the entropy a logarithmic term in addition to a classical contribution as well. Conversely, at low temperatures, it is shown that both the renormalized Casimir free energy and internal energy are dominated by the vacuum energy at zero temperature. It is also shown that the entropy obeys the third law of thermodynamics.

description: We investigate the properties of a harmonic chain in contact with a thermal bath at one end and subjected, at its other end, to a periodic force. The particles also undergo a random velocity reversal action, which results in a finite heat conductivity of the system. We prove the approach of the system to a time periodic state and compute the heat current, equal to the time averaged work done on the system, in that state. This work approaches a finite positive value as the length of the chain increases. Rescaling space, the strength and/or the period of the force leads to a macroscopic temperature profile corresponding to the stationary solution of a continuum heat equation with Dirichlet-Neumann boundary conditions.

description: (27) Diplosoma listerianum (H. Milne Edwards, 1841)
Status in U.K. – cryptogenic.
Diplosoma listerianum has been recorded at several monitoring programme sites, most years since 2012, most recently from scrape samples. It has also been recorded from renewable energy structures (Want et al. 2017). It is difficult to identify with certainty and is likely to have been present more widely but recorded as Didemnidae. A record from 2012 was listed as D. listerianum / spongiforme.
It is listed as non-native in the Mediterranean (Airoldi et al. 2015; López-Legentil and Legentil 2015) and as invasive in the Netherlands (Gittenberger 2007). Molecular studies by Pérez-Portela et al. (2013) identified cryptic species and evidence of anthropogenic introductions but did not determine the native range. The species should be considered cryptogenic in the U.K. Diplosoma spongiforme (Giard, 1872) is likewise also considered here as cryptogenic in Europe. Both D. spongiforme and D. listerianum were recorded from Orkney by Want et al. (2017) growing on marine renewable energy structures.

However, little observational evidence has been presented for such inflows, which are expected to be only a few km s$^{-1}$ in the central regions of the disk, i.e. within three disk scale-lengths, but could reach of order 50-100 km s$^{-1}$ in the very outer disk. The effects of systematic inflow on the 2-d velocity field are examined and it is shown that these are quite similar to those produced by geometric warps of the disks, with twist distortions of both the kinematic major and minor axes. This makes it potentially difficult to distinguish between these in practice. By comparing the handedness of the observed twisting of the kinematic axes and of the spiral arms for a sample of nearby galaxies, we find (assuming that the spiral arms are generally trailing) that the effects of warps are in fact likely to dominate over the effects of radial inflows. However, the common practice of treating these twist distortions of the kinematic major and minor axes as being due only to warps can lead, for galaxies of low-to-intermediate inclinations, to substantial underestimates of any systematic inflow.

description: We present nuclear spectral energy distributions (SEDs) from 1 to 18 micron of a small sample of nearby, nearly face-on and undisturbed Seyfert galaxies without prominent nuclear dust lanes. These nuclear SEDs probe the central ~35 pc of the galaxies, on average, and include photometric and spectroscopic infrared (IR) data. We use these SEDs, the clumpy torus models of Nenkova et al. and a Bayesian approach to study the sensitivity of different IR wavelengths to the torus parameters. We find that high angular resolution 8-13 micron spectroscopy alone reliably constrains the number of clumps and their optical depth (N0 and tau_V). On the other hand, we need a combination of mid- and near-IR subarcsecond resolution photometry to constrain torus width and inclination, as well as the radial distribution of the clouds (sigma, i and q). For flat radial profiles (q=0,1), it is possible to constrain the extent of the mid-IR-emitting dust within the torus (Y) when N-band spectroscopy is available, in addition to near-IR photometry. Finally, by fitting different combinations of average and individual Seyfert 1 and Seyfert 2 data, we find that, in general, for undisturbed, nearly face-on Seyferts without prominent nuclear dust lanes, the minimum combination of data necessary to reliably constrain all the torus parameters is J+K+M-band photometry + N-band spectroscopy.

Anankastic Conditionals and Salient Goals
Creators: name: Huitink, Janneke
Publisher: name: Proceedings of Sinn und Bedeutung
Year: 2019

description: In this paper I evaluate two recent analyses of anankastic conditionals, the designated goal analysis by von Fintel and Iatridou (2004) and the modal base restriction account of Penka, Krasikowa and von Stechow (2004). I will show that both theories make the wrong predictions in scenarios with multiple non-conflicting goals. To solve the problem, I propose that ordering sources select salient goals from the context of utterance. For anankastic conditionals the ordering source selects the goal described in the if-clause. At the end of this paper I present some arguments against the recent analysis of anankastic conditionals as counterfactuals by von Stechow, Krasikowa and Penka (2004).

Non-monotonic dependence of projection probabilities as a function of distinguishability

description: Typically, quantum superpositions, and thus measurement projections of quantum states involving interference, decrease (or increase) monotonically as a function of increased distinguishability. Distinguishability, in turn, can be a consequence of decoherence, for example caused by the (simultaneous) loss of excitation or due to inadequate mode matching (either deliberate or indeliberate). It is known that for some cases of multi-photon interference, non-monotonic decay of projection probabilities occurs, which has so far been attributed to interference between four or more two photons. We show that such a non-monotonic behaviour of projection probabilities is not unnatural, and can also occur for single-photon and even semiclassical states. Thus, while the effect traces its roots from indistinguishability and thus interference, the states for which this can be observed do not need to have particular quantum features.

description: The analytic galactic wind model derived by Chevalier and Clegg in 1985 (CC85) assumes $\textit{uniform}$ energy and mass-injection within the starburst galaxy nucleus. However, the structure of nuclear star clusters, bulges, and star-forming knots are non-uniform. We generalize to cases with spherically-symmetric energy/mass injection that scale as $r^{-Δ}$ within the starburst volume $R$, providing solutions for $Δ= 0$, 1/2, 1, 3/2, and 2. In marked contrast with the CC85 model ($Δ=0$), which predicts zero velocity at the center, for a singular isothermal sphere profile ($Δ=2$), we find that the flow maintains a $\textit{constant}$ Mach number of $\mathcal{M}=\sqrt{3/5} \simeq 0.77$ throughout the volume. The fast interior flow can be written as $v_{r < R} = (\dot{E}_T/3\dot{M}_T)^{1/2} \simeq 0.41 \, v_\infty$, where $v_\infty$ is the asymptotic velocity, and $\dot{E}_T$ and $\dot{M}_T$ are the total energy and mass injection rates. For $v_\infty \simeq 2000 \, \mathrm{km \, s^{-1}}$, $v_{r

description: This paper aims at providing a survey on the problems that can be easily addressed by cellular automata in bioinformatics. Some of the authors have proposed algorithms for addressing some problems in bioinformatics but the application of cellular automata in bioinformatics is a virgin field in research. None of the researchers has tried to relate the major problems in bioinformatics and find a common solution. Extensive literature surveys were conducted. We have considered some papers in various journals and conferences for conduct of our research. This paper provides intuition towards relating various problems in bioinformatics logically and tries to attain a common frame work for addressing the same.

description: In 1927 Louis de Broglie proposed an alternative approach to standard quantum mechanics known as the double solution program (DSP) where particles are represented as bunched fields or solitons guided by a base (weaker) wave. DSP evolved as the famous de Broglie-Bohm pilot wave interpretation (PWI) also known as Bohmian mechanics but the general idea to use solitons guided by a base wave to reproduce the dynamics of the PWI was abandonned. Here we propose a nonlinear scalar field theory able to reproduce the PWI for the Schrödinger and Klein-Gordon guiding waves. Our model relies on a relativistic `phase harmony' condition locking the phases of the solitonic particle and the guiding wave. We also discuss an extension of the theory for the $N$ particles cases in presence of entanglement and external (classical) electromagnectic fields.

description: The local structure of a fractal set is described by its dimension $D$, which is the exponent of a power-law relating the mass ${\cal N}$ in a ball to its radius $ε$: ${\cal N}\sim ε^D$. It is desirable to characterise the {\em shapes} of constellations of points sampling a fractal measure, as well as their masses. The simplest example is the distribution of shapes of triangles formed by triplets of points, which we investigate for fractals generated by chaotic dynamical systems. The most significant parameter describing the triangle shape is the ratio $z$ of its area to the radius of gyration squared. We show that the probability density of $z$ has a phase transition: $P(z)$ is independent of $ε$ and approximately uniform below a critical flow compressibility $β_{\rm c}$, but for $β>β_{\rm c}$ it is described by two power laws: $P(z)\sim z^{α_1}$ when $1\gg z\gg z_{\rm c}(ε)$, and $P(z)\sim z^{α_2}$ when $z\ll z_{\rm c}(ε)$.

description: General movement assessment (GMA) of infant movement videos (IMVs) is an effective method for early detection of cerebral palsy (CP) in infants. We demonstrate in this paper that end-to-end trainable neural networks for image sequence recognition can be applied to achieve good results in GMA, and more importantly, augmenting raw video with infant body parsing and pose estimation information can significantly improve performance. To solve the problem of efficiently utilizing partially labeled IMVs for body parsing, we propose a semi-supervised model, termed SiamParseNet (SPN), which consists of two branches, one for intra-frame body parts segmentation and another for inter-frame label propagation. During training, the two branches are jointly trained by alternating between using input pairs of only labeled frames and input of both labeled and unlabeled frames. We also investigate training data augmentation by proposing a factorized video generative adversarial network (FVGAN) to synthesize novel labeled frames for training. When testing, we employ a multi-source inference mechanism, where the final result for a test frame is either obtained via the segmentation branch or via propagation from a nearby key frame. We conduct extensive experiments for body parsing using SPN on two infant movement video datasets, where SPN coupled with FVGAN achieves state-of-the-art performance. We further demonstrate that SPN can be easily adapted to the infant pose estimation task with superior performance. Last but not least, we explore the clinical application of our method for GMA. We collected a new clinical IMV dataset with GMA annotations, and our experiments show that SPN models for body parsing and pose estimation trained on the first two datasets generalize well to the new clinical dataset and their results can significantly boost the CRNN-based GMA prediction performance.

description: This survey reviews the existing literature on the most relevant Bayesian inference methods for univariate and multivariate GARCH models. The advantages and drawbacks of each procedure are outlined as well as the advantages of the Bayesian approach versus classical procedures. The paper makes emphasis on recent Bayesian non-parametric approaches for GARCH models that avoid imposing arbitrary parametric distributional assumptions. These novel approaches implicitly assume infinite mixture of Gaussian distributions on the standardized returns which have been shown to be more flexible and describe better the uncertainty about future volatilities. Finally, the survey presents an illustration using real data to show the flexibility and usefulness of the non-parametric approach.
