Exact asymptotics in eigenproblems for fractional Brownian covariance operators

description: Many results in the theory of Gaussian processes rely on the eigenstructure of the covariance operator. However, eigenproblems are notoriously hard to solve explicitly and closed form solutions are known only in a limited number of cases. In this paper we set up a framework for the spectral analysis of the fractional type covariance operators, corresponding to an important family of processes, which includes the fractional Brownian motion and its noise. We obtain accurate asymptotic approximations for the eigenvalues and the eigenfunctions. Our results provide a key to several problems, whose solution is long known in the standard Brownian case, but was missing in the more general fractional setting. This includes computation of the exact limits of $L^2$-small ball probabilities and asymptotic analysis of singularly perturbed integral equations, arising in mathematical physics and applied probability.

description: The finding of a double red clump in the luminosity function of the Milky Way bulge has been interpreted as evidence for an X-shaped structure. Recently, an alternative explanation has been suggested, where the double red clump is an effect of multiple stellar populations in a classical spheroid. In this letter we provide an observational assessment of this scenario and show that it is not consistent with the behaviour of the red clump across different lines of sight, particularly at high distances from the Galactic plane. Instead, we confirm that the shape of the red clump magnitude distribution closely follows the distance distribution expected for an X-shaped bulge at critical Galactic latitudes. We also emphasize some key observational properties of the bulge red clump that should not be neglected in the search for alternative scenarios.

description: In this paper we prove global regularity for the full water waves system in 3 dimensions for small data, under the influence of both gravity and surface tension. This problem presents essential difficulties which were absent in all of the earlier global regularity results for other water wave models. To construct global solutions we use a combination of energy estimates and matching dispersive estimates. There is a significant new difficulty in proving energy estimates in our problem, namely the combination of slow pointwise decay of solutions (no better than $|t|^{-5/6}$) and the presence of a large, codimension 1, set of quadratic time-resonances. To deal with such a situation we propose here a new mechanism, which exploits a non-degeneracy property of the time-resonant hypersurfaces and some special structure of the quadratic part of the nonlinearity, connected to the conserved energy of the system. The dispersive estimates rely on analysis of the Duhamel formula in the Fourier space. The main contributions come from the set of space-time resonances, which is a large set of dimension 1. To control the corresponding bilinear interactions we use Harmonic Analysis techniques, such as orthogonality arguments in the Fourier space and atomic decompositions of functions. Most importantly, we construct and use a refined norm which is well adapted to the geometry of the problem.

 Lectotype (designated here): –– INDIA, Bombay District, December 1891, Lisboa 03 (K barcode K000245013!), Fig. 2.
 Notes:–– Stapf (1892) described Tripogon lisboae based on specimens collected from India. He cited the four specimens in the protologue as “ India, from Canara and Mysore to Mt. Abu: Canara and Mysore, Law; Bombay Presidency, Lisboa; on rocks near the Carley Coves, near Poonah, Jacquemont, 581; Rajputana, Mt. Abu, on rocks, Duthie, 6788”. The search for the original materials in various herbaria (B, BLAT, BSI, BSID, C, CAL, CALI, E, K, MH, P, RHT, W) revealed the existence of four sheets at K herbarium (K000245013!, K000245014!, K000245015!, K000245016!). Among them, the sheet (barcode K000245013) from India with the drawings of dissected floral parts with annotations by the author which matches perfectly with the original description is selected here as the lectotype of T. lisboae.

description: The Wiener-Khinchin theorem shows how the power spectrum of a stationary random signal $I(t)$ is related to its correlation function $\left\langle I(t)I(t+τ)\right\rangle$. We consider non-stationary processes with the widely observed aging correlation function $\langle I(t) I(t+τ) \rangle \sim t^γϕ_{\rm EN}(τ/t)$ and relate it to the sample spectrum. We formulate two aging Wiener-Khinchin theorems relating the power spectrum to the time and ensemble averaged correlation functions, discussing briefly the advantages of each. When the scaling function $ϕ_{\rm EN}(x)$ exhibits a non-analytical behavior in the vicinity of its small argument we obtain aging $1/f$ type of spectrum. We demonstrate our results with three examples: blinking quantum dots, single file diffusion and Brownian motion in a logarithmic potential, showing that our approach is valid for a wide range of physical mechanisms.

description: Electron transport is conventionally determined by the momentum-relaxing scattering of electrons by the host solid and its excitations. The electrical resistance is set by geometrical factors and the resistivity, which is a microscopic property of the solid. Hydrodynamic fluid flow through channels, in contrast, is determined by geometrical factors, boundary scattering and the viscosity of the fluid, which is governed by momentum-conserving internal collisions. A long-standing question in the physics of solids, brought into focus by the advent of new calculational techniques, has been whether the viscosity of the electron fluid plays an observable role in determining the resistance. At first sight this seems unlikely, because in almost all known materials the rate of momentum-relaxing collisions dominates that of the momentum-conserving ones that give the viscous term. Here, we show this is not always the case. We report experimental evidence that the resistance of restricted channels of the ultra-pure two-dimensional metal PdCoO$_2$ has a large viscous contribution. Comparison with theory allows an estimate of the electronic viscosity in the range between $6\times 10^{-3}$~kg(ms)$^{-1}$ and $3\times 10^{-4}$~kg(ms)$^{-1}$, which brackets that of water at room temperature.

Combination of small angle neutron scattering and electron microscopy opens new vistas in ultrastructural studies of photosynthetic membranes
Creators: name: Ünnep, Renáta
Publisher: name: Zenodo
Year: 2023

description: Photosynthesis is the source of almost all energy used by living organisms and 80 % of humankind’s energy use. Understanding the processes of adaptation and protection mechanisms of photosynthetic organisms is essential because photosynthetic organisms, including crop plants, tend to face extreme environmental conditions due to global climate change. Photosynthetic machineries are highly organized systems. The light reactions in oxygenic photosynthetic organisms occur in the multilamellar thylakoid membrane system, which contains virtually all components of the light energy conversion apparatus. Our knowledge about the structure and structural dynamics of thylakoid membrane systems in the mesoscopic size range is incomplete. In this range, small-angle neutron scattering (SANS) provides a unique possibility for studies under close to the physiological conditions. SANS contains accurate structural information on large statistical population with time resolutions of a few seconds or minutes. Electron microscopy (EM) provides more detailed information on the ultrastructure but it is not suited to monitor the kinetics of membrane reorganizations. Therefore, SANS and EM techniques complement well each other and their combination opens new vistas in ultrastructural studies of membranes during diverse adaptation mechanisms to changing environmental conditions. The presentation will focus on (i) membrane disorganization associated with a novel energy-dissipation mechanism in desert-crust cyanobacteria, (ii) balanced feeding of the two photosystems during spectral changes of the incident light (chromatic adaptation) in green algae, and (iii) combination of EM and SANS during physiologically important mechanisms and different abiotic stress factors in leaves and whole plants.

description: We extend the Heegaard Floer homological definition of spectral order for closed contact 3-manifolds due to Kutluhan, Matić, Van Horn-Morris, and Wand to contact 3-manifolds with convex boundary. We show that the order of a codimension zero contact submanifold bounds the order of the ambient manifold from above. As the neighborhood of an overtwisted disk has order zero, we obtain that overtwisted contact structures have order zero. We also prove that the order of a small perturbation of a $2π$ Giroux torsion domain has order at most two, hence any contact structure with positive Giroux torsion has order at most two (and, in particular, a vanishing contact invariant).

description: Innovative ways of harnessing sustainable energy are needed to meet the world's ever-increasing energy demands. Supercapacitors may contribute, as they can convert waste heat to electricity through cyclic charging and discharging at different temperatures. Herein, we use an analytically-solvable model of a cylindrical pore filled with a single file of ions to identify optimal conditions for heat-to-electricity conversion with supercapacitors. We consider Stirling and Ericsson-like charging cycles and show that the former or latter yields more work when a supercapacitor operates under charge or voltage limitations, respectively. Both cycles yield the most work for pores almost as narrow as the size of the ions they contain, as is the case for energy storage with supercapacitors. In contrast to energy storage, which can be maximised by ionophobic pores, such pores do not yield the best heat-to-electricity conversion, independently of the applied potential. Instead, we find that for a given pore size, a moderately ionophilic pore harvests more work than ionophobic and strongly ionophilic pores.
Interpreting the radio/X-ray correlation of black hole sources based on the accretion-jet model

description: Two types of correlations between the radio and X-ray luminosities ($L_R$ and $L_X$) have been found in black hole X-ray binaries. For some sources, they follow the `original' type of correlation which is described by a single power-law. Later it was found that some other sources follow a different correlation consisting of three power-law branches, with each branch having different power-law indexes. In this work, we explain these two types of correlation under the coupled accretion--jet model. We attribute the difference between these two types of sources to the different value of viscosity parameter $α$. One possible reason for different $α$ is the different configuration of magnetic field in the accretion material coming from the companion stars. For the `single power-law' sources, their $α$ is high; so their accretion is always in the mode of advection-dominated accretion flow (ADAF) for the whole range of X-ray luminosity. For those `hybrid power-law' sources, the value of $α$ is small so their accretion mode changes from an ADAF to a luminous hot accretion flow, and eventually to two-phase accretion as the accretion rate increases. Because the dependence of radiative efficiency on the mass accretion rate is different for these three accretion modes, different power-law indexes in the $L_R--L_X$ correlation are expected. Constraints on the ratio of the mass loss rate into the jet and the mass accretion rate in the accretion flow are obtained, which can be tested in future by radiative magnetohydrodynamic numerical simulations of jet formation.

description: It is increasingly important to enable privacy-preserving inference for cloud services based on Transformers. Post-quantum cryptographic techniques, e.g., fully homomorphic encryption (FHE), and multi-party computation (MPC), are popular methods to support private Transformer inference. However, existing works still suffer from prohibitively computational and communicational overhead. In this work, we present, Primer, to enable a fast and accurate Transformer over encrypted data for natural language processing tasks. In particular, Primer is constructed by a hybrid cryptographic protocol optimized for attention-based Transformer models, as well as techniques including computation merge and tokens-first ciphertext packing. Comprehensive experiments on encrypted language modeling show that Primer achieves state-of-the-art accuracy and reduces the inference latency by 90.6% ~ 97.5% over previous methods.

description: A common challenge in designing and implementing information retrieval systems in the healthcare industry is the integration of systems supplied by different vendors. Vendors usually produce closed systems (systems without any electronic interfaces to share information with other systems) and this hinders free sharing of information among different medical systems. Integrated health information systems that link the data from hospitals, health plan providers, and regulators would not only improve efficiency, but also would save money. Medical records that are digitally stored in servers need to be accessible from different applications. If products of different vendors were to communicate better and share medical data, it would significantly improve usefulness of information technology applications in healthcare industry. The purpose of this research is to explore system integration issues through a case study of Vegatip (Vegatip is an alias to protect the identity of the real company), a records management company that serves the healthcare industry.  This research will identify the problems faced while attempting to integrate Vegatip's servers that hold digitized images with the medical practice management systems that the hospitals and physicians' offices use.  The research will define practice management systems and describe available commercial systems, will describe issues related to systems integration, and will describe the procedure used to recommend an integration method to connect a given practice management system to the server.  Limitations associated with various options of systems integration will also be discussed.

description: Spacetime with general linear vector distortion is introduced. Thus, the torsion and the nonmetricity of the affine connection are assumed to be proportional to a vector field (and not its derivatives). The resulting two-parameter family of non-Riemannian geometries generalises the conformal Weyl geometry and some other interesting special cases. Taking into account the leading order quadratic curvature correction to the Einstein-Hilbert action results uniquely in the one-parameter extension of the Starobinsky inflation known as the alpha-attractor. The most general quadratic curvature action introduces, in addition to the canonical vector kinetic term, novel ghost-free vector-tensor interactions.

description: This paper describes a usability study of Botanical Pride, a contributor-supplied metadata creation tool which allows botany enthusiasts to create metadata for images of botanical specimens. Two versions of the interface were tested: a Definitions Only version that included definitions of metadata elements and a Definitions+Examples version that included definitions of metadata elements and one or more examples of metadata element values. Participants used each version of the interface to create a metadata record for a different selected image. Testing was conducted via the World Wide Web. Usability was measured by responses to a satisfaction questionnaire and by mean task completion times. Recommendations are made for the use of examples in the help for Botanical Pride. Implications for the design of future studies of metadata creation tools for use by non-metadata experts are considered.

description: This paper analyzes the visions, schemas, and vocabularies of prominent rights expression languages, including Creative Commons, METS, ODRL, and MPEG-21. The paper extends Michel Callon's sociological insight that all forms of human agency are multiple and diverse. Callon argues, in the context of economic sociology, that one must constantly decide between a strategy emphasizing "framing" as the norm with "overflows" treated as leaks, or conversely a strategy accepting "overflows" as the norm with "framing" as inherently imperfect. Callon's categories are extended, through a modeling exercise, to the classification of current metadata schemes. The analysis suggests that metadata developers should explore what semantic choices and strictures are left out of metadata schemes, as well as those that are included. Such a thought exercise is especially useful in distinguishing areas suited for XML rights markup extensions.

description: Using numerical simulations we present the accretion of supersonic winds onto a rotating black hole in three dimensions. We study five representative directions of the wind with respect to the axis of rotation of the black hole and focus on the evolution and stability of the high density shock cone that is formed during the process. We explore both, the regime in which the shock cone is expected to be stable in order to confirm previous results obtained with two dimensional simulations, and the regime in which the shock cone is expected to show a flip-flop type of instability. The methods used to attempt triggering the instability were first the accumulation of numerical errors and second the explicit application of a perturbation on the velocity field after the shock-cone was formed. The result is negative, that is, we did not find the flip-flop instability within the parameter space we explored, which includes cases that are expected to be unstable.

description: A lossless beam-splitter has certain (complex-valued) probability amplitudes for sending an incoming photon into one of two possible directions. We use elementary laws of classical and quantum optics to obtain general relations among the magnitudes and phases of these probability amplitudes. Proceeding to examine a pair of (nearly) single-mode wavepackets in the number-states |n1> and |n2> that simultaneously arrive at the splitter's input ports, we find the distribution of photon-number states at the output ports using an argument inspired by Feynman's scattering analysis of indistinguishable Bose particles. The result thus obtained coincides with that of the standard quantum-optical treatment of beam-splitters via annihilation and creation operators a and a†. A simple application of the Feynman method provides a form of justification for the Bose enhancement implicit in the well-known formulas a|n>=sqrt(n)|n-1> and a†|n>=sqrt(n+1)|n+1>.

description: This study proposes the need for secure remote communications to protect the data and information infrastructure of an organization. Several common remote access technologies are discussed, along with their various flaws and strengths. End-to-end encrypted VPN tunnels appear to be the most secure method of remote network access, and are discussed in terms of their performance and implementation details. A performance test for a VPN tunnel was performed to highlight the differences in network latency and throughput when additional levels of security are added. Cryptographic functions like hashing and Perfect Forward Secrecy are discussed and compared along with different cryptographic algorithms like DES and 3DES. Ultimately, the differences in performance between cryptographic configurations are slight, though could be amplified by network conditions.

description: Animals are faced with a variety of dangers or threats, which are increasing in frequency with ongoing environmental change. While our understanding of fearfulness of such dangers is increasing in the context of predation and parasitism risk, the extent to which non-trophic, interspecific dangers elicit fear in animals remains less appreciated. We provide an experimental test for fear responses of savannah ungulates to a dominant and aggressive megaherbivore, the African bush elephant (Loxodonta africana), and contrast responses to an apex predator known to elicit fear in this system. Using an automated behavioural response system, we contrast vigilance and run responses of ungulates to elephant, leopard (Panthera pardus), and control (red-chested cuckoo Cuculus solitarius) vocalizations. Overall, we find that ungulates responded to elephant calls, both in terms of an increase in run and vigilance responses relative to controls. The magnitude of most behavioural responses (four of six considered) to elephant vocalizations were not significantly different than responses to leopards. These results suggest that megaherbivores can elicit strong non-trophic fear responses by ungulates and call to broaden frameworks on fear to consider dominant species, such as megaherbivores, as key modifiers of fear-induced interactions.

description: We consider a variant of the Nojiri-Odintsov covariant Horava-like gravitational model, where diffeomorphism invariance is broken dynamically via a non-standard coupling to a perfect fluid. The theory allows to address some of the potential instability problems present in Horava-Lifshitz gravity due to explicit diffeomorphism invariance breaking. The fluid is instead constructed from a scalar field constrained by a Lagrange multiplier. In fact, the Lagrange multiplier construction allows for an extension of the Horava-like model to include the scalar field of mimetic gravity, an extension which we thoroughly explore. By adding a potential for the scalar field, we show how one can reproduce a number of interesting cosmological scenarios. We then turn to the study of perturbations around a flat FLRW background, showing that the fluid in question behaves as an irrotational fluid, with zero sound speed. To address this problem, we consider a modified version of the theory, adding higher derivative terms in a way which brings us beyond the Horndeski framework. We compute the sound speed in this modified higher order mimetic Horava-like model and show that it is non-zero, which means that perturbations therein can be sensibly defined. Caveats to our analysis, as well as comparisons to projectable Horava-Lifshitz gravity, are also discussed. In conclusion, we present a theory of gravity which preserves diffeomorphism invariance at the level of the action but breaks it dynamically in the UV, reduces to General Relativity in the IR, allows the realization of a number of interesting cosmological scenarios, is well defined when considering perturbations around a flat FLRW background, and features cosmological dark matter emerging as an integration constant.

Hudibras

description: This Master's paper consists of a descriptive catalog of sixty-nine editions of Samuel Butler's epic poem "Hudibras" from a collection of Butler's works donated to the Rare Book Collection at the University of North Carolina at Chapel Hill by Robert W. Severance.  This catalog does not represent the entire Severance collection nor does it represent the Rare Book Collection's entire holdings of "Hudibras".  Rather it is limited only to the editions of the poem from the Severance collection published in the seventeenth and eighteenth centuries (the Severance collection includes editions published through the twentieth century).  Each of the sixty-nine one-page descriptions provides a title page transcription, collation, pagination, list of contents, description of type and page size, and description of illustrations.  While the catalog is not an all-inclusive representation of the seventeenth and eighteenth editions of the poem, it is a fairly comprehensive description of the publishing history of "Hudibras" before 1800.

description: We present broadband observations and spectral modeling of PKS B0008-421, and identify it as an extreme gigahertz-peaked spectrum (GPS) source. PKS B0008-421 is characterized by the steepest known spectral slope below the turnover, close to the theoretical limit of synchrotron self-absorption, and the smallest known spectral width of any GPS source. Spectral coverage of the source spans from 0.118 to 22 GHz, which includes data from the Murchison Widefield Array and the wide bandpass receivers on the Australia Telescope Compact Array. We have implemented a Bayesian inference model fitting routine to fit the data with various absorption models. We find that without the inclusion of a high-frequency exponential break the absorption models can not accurately fit the data, with significant deviations above and below the peak in the radio spectrum. The addition of a high-frequency break provides acceptable spectral fits for the inhomogeneous free-free absorption and double-component synchrotron self-absorption models, with the inhomogeneous free-free absorption model statistically favored. The requirement of a high-frequency spectral break implies that the source has ceased injecting fresh particles. Additional support for the inhomogeneous free-free absorption model as being responsible for the turnover in the spectrum is given by the consistency between the physical parameters derived from the model fit and the implications of the exponential spectral break, such as the necessity of the source being surrounded by a dense ambient medium to maintain the peak frequency near the gigahertz region. The discovery of PKS B0008-421 suggests that the next generation of low radio frequency surveys could reveal a large population of GPS sources that have ceased activity, and that a portion of the ultra-steep spectrum source population could be composed of these GPS sources in a relic phase.

description: We derive an inequality that relates nodal set and eigenvalues of a class of twisted Dirac operators on closed surfaces and point out how this inequality naturally arises as an eigenvalue estimate for the $\rm Spin^c$ Dirac operator. This allows us to obtain eigenvalue estimates for the twisted Dirac operator appearing in the context of Dirac-harmonic maps and their extensions, from which we also obtain several Liouville type results.

The Cabinet of Curiosities: Recreating the Renaissance Experience

description: The cabinet of curiosities, or collection of the exotic and the obscure, was a product of the Renaissance.  Efforts by the elite to acquire and display natural and man-made marvels served a dual purpose: to illustrate prestige and to support intellectual pursuits.  In regard to the latter, this paper suggests three uses of the Renaissance cabinet: as a refuge, conducive to creativity and critical thinking; as a laboratory, facilitating experimentation via the arrangement or observation of objects; and as a forum, to inspire intellectual conversation. Linking the historical cabinet to its contemporary counterparts, this paper examines similar attributes in three modern exhibits on display, or displayed, at the University of Colorado Boulder, the University of Minnesota Twin Cities, and the Canadian Museum of Civilization.  It concludes that the cabinet of curiosities remains a relevant model for exhibit design, that the appeal of the unexpected is timeless.

description: This study examines the use of trusted digital repository tools and standards for self-audit in digital repositories. While there has been increasing attention given to external audit and certification of trusted digital repositories, there has not yet been a cross-institutional study of repository self-audits.
        Describing a series of semi-structured interviews with six information professionals employed at six university digital repositories, this study examines these repositories’ experiences with self-audit. The study explores the tools that are being used for self-audit, how self-audits are conducted, and the value of self-audit to repositories and their stakeholders. Findings from this study provide some insight into the current state of self-audit in digital repositories, and the paper also suggests areas for improvement and future research in this field.

description: Recent work has focused on the problem of nonparametric estimation of information divergence functionals. Many existing approaches are restrictive in their assumptions on the density support set or require difficult calculations at the support boundary which must be known a priori. The MSE convergence rate of a leave-one-out kernel density plug-in divergence functional estimator for general bounded density support sets is derived where knowledge of the support boundary is not required. The theory of optimally weighted ensemble estimation is generalized to derive a divergence estimator that achieves the parametric rate when the densities are sufficiently smooth. The asymptotic distribution of this estimator and some guidelines for tuning parameter selection are provided. Based on the theory, an empirical estimator of Rényi-$α$ divergence is proposed that outperforms the standard kernel density plug-in estimator, especially in high dimension. The estimator is shown to be robust to the choice of tuning parameters. As an illustration, we use the estimator to estimate bounds on the Bayes error rate of a classification problem.

description: Over the last decade, law firms have dramatically increased the availability and usage of information technology in their offices. This paper seeks to explore the relationship between productivity and information technology within the legal community. Combining Consumer Population Survey data compiled by the Bureau of Labor Statistics with several different surveys of law firms to provide evidence of information technology deployment, the paper seeks to understand why productivity does not seem to be increasing with the broadening usage of information technology in the legal profession and how the definition of productivity and attorney billing practices need to change in order to reflect a shifting paradigm.
