description: We take the tensor network describing explicit p-adic CFT partition functions proposed in [1], and considered boundary conditions of the network describing a deformed Bruhat-Tits (BT) tree geometry. We demonstrate that this geometry satisfies an emergent graph Einstein equation in a unique way that is consistent with the bulk effective matter action encoding the same correlation function as the tensor network, at least in the perturbative limit order by order away from the pure BT tree. Moreover, the (perturbative) definition of the graph curvature in the Mathematics literature naturally emerges from the consistency requirements of the emergent Einstein equation. This could provide new insights into the understanding of gravitational dynamics potentially encoded in more general tensor networks.

description: Context: Future astrometric missions such as SIM PlanetQuest need very stable reference stars. K giants have large luminosities, which place them at large distances and thus the jitter of their photocenters by companions is relatively small. Therefore K giants would be best suited as references. To confirm this observationally a radial velocity survey is performed to quantify the level of intrinsic variability in K giants. Aims: From this radial velocity survey we present 34 K giants with an observed standard deviation of the radial velocity of less than 20 m/s. These stars are considered ``stable'' and can be used as radial velocity standards. Methods: The radial velocity survey contains 179 K giants. All K giants have a declination between -30 and +65 degrees and visual magnitude of 3-6 mag. The Coude Auxiliary Telescope (CAT) at UCO/Lick Observatory is used to obtain radial velocities with an accuracy of 5-8 m/s. The number of epochs for the 34 stable stars ranges from 11 to 28 with a total timespan of the observations between 1800 and a little over 2200 days. Results: The observational results of the 34 ``stable'' stars are shown together with a discussion about their position in the M_{V} vs. B-V diagram and some conclusions concerning the radial velocity variability of K giants. These results are in agreement with the theoretical predictions. K giants in a certain range of the M_{V} vs. B-V diagram are suitable reference stars.

description: Ternary and quaternary cubic c-AlxIn1-xN/GaN and c-AlxGayIn1-x-y/GaN heterostructures lattice-matched to c-GaN on freestanding 3C-SiC substrates were grown by plasma-assisted molecular beam epitaxy. The c-AlxGayIn1-x-y alloy permits the independent control of band gap and lattice parameter. The ternary and quaternary films were grown at 620 C. Different alloy compositions were obtained by varying the Al and Ga fluxes. The alloy composition was measured by Energy Dispersive X-ray Spectroscopy (EDX) and Rutherford Backscattering Spectrometry (RBS). X-ray reciprocal space map of asymmetric (-1-13) reflex were used to measure the lattice parameters and to verify the lattice match between the alloy and the c-GaN buffer.

description: We present a photometric and spectroscopic study of four G-K dwarfs, namely HD 166, epsilon Eri, chi1 Ori and kappa1 Cet. In three cases, we find a clear spatial association between photospheric and chromospheric active regions. For chi1 Ori we do not find appreciable variations of photospheric temperature, and chromospheric Halpha emission. We applied a spot/plage model to the observed rotational modulation of temperature and flux to derive spot/plage parameters and to reconstruct a rough three-dimensional map of the outer atmosphere of kappa1 Cet, HD 166 and epsilon Eri.

Interplay and competition between disorder and flat band in an interacting Creutz ladder

description: We clarify the interplay and competition between disorder and flat band in the Creutz ladder with inter-particle interactions focusing on the system's dynamics. Without disorder, the Creutz ladder exhibits flat-band many-body localization (FMBL). In this work, we find that disorder generates drastic effects on the system, i.e., addition of it induces a thermal phase first and further increase of it leads the system to the conventional many-body-localized (MBL) phase. The competition gives novel localization properties and unconventional quench dynamics to the system. We first draw the global sketch of the localization phase diagram by focusing on the two-particle system. The thermal phase intrudes between the FMBL and MBL phases, the regime of which depends on the strength of disorder and interactions. Based on the two-particle phase diagram and the properties of the quench dynamics, we further investigate finite-filling cases in detail. At finite-filling fractions, we again find that the interplay/competition between the interactions and disorder in the original flat-band Creutz ladder induces thermal phase, which separates the FMBL and MBL phases. We also verify that the time evolution of the system coincides with the static phase diagrams. For suitable fillings, the conservation of the initial-state information and low-growth entanglement dynamics are also observed. These properties depend on the strength of disorder and interactions.

description: Meson Green's functions and decay constants $f_Γ$ in different channels $Γ$ are calculated using the Field Correlator Method. Both, spectrum and $f_Γ$, appear to be expressed only through universal constants: the string tension $σ$, $α_s$, and the pole quark masses. For the $S$-wave states the calculated masses agree with the experimental numbers within $\pm 5$ MeV. For the $D$ and $D_s$ mesons the values of $f_{\rm P} (1S)$ are equal to 210(10) and 260(10) MeV, respectively, and their ratio $f_{D_s}/f_D$=1.24(3) agrees with recent CLEO experiment. The values $f_{\rm P}(1S)=182, 216, 438$ MeV are obtained for the $B$, $B_s$, and $B_c$ mesons with the ratio $f_{B_s}/f_B$=1.19(2) and $f_D/f_B$=1.14(2). The decay constants $f_{\rm P}(2S)$ for the first radial excitations as well as the decay constants $f_{\rm V}(1S)$ in the vector channel are also calculated. The difference of about 20% between $f_{D_s}$ and $f_D$, $f_{B_s}$ and $f_B$ directly follows from our analytical formulas.

description: The thermodynamics-gravity conjecture reveals that one can derive the gravitational field equations by using the first law of thermodynamics and vice versa. Considering the entropy associated with the horizon in the form of non-extensive Tsallis entropy, $S\sim A^β$ here we first derive the corresponding gravitational field equations by applying the Clausius relation $δQ=T δS$ to the horizon. We then construct the Friedmann equations of Friedmann-Lemaître-Robertson-Walker (FLRW) universe based on Tsallis modified gravity (TMG). Moreover, in order to constrain the cosmological parameters of TMG model, we use observational data, including Planck cosmic microwave background (CMB), weak lensing, supernovae, baryon acoustic oscillations (BAO), and redshift-space distortions (RSD) data. Numerical results indicate that TMG model with a quintessential dark energy is more compatible with the low redshift measurements of large scale structures by predicting a lower value for the structure growth parameter $σ_8$ with respect to $Λ$CDM model. This implies that TMG model would slightly alleviate the $σ_8$ tension.

Automated decomposition of electromyographic signals recorded with surface electrode arrays
Creators: name: Chen, Yunquan
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents results of various investigations which led to the development and validation of a new system for multi-channel surface electromyographic (EMG) recording for clinical examinations (McSERCE) and of a new method for multi-channel surface EMG decomposition (McSED). To obtain individual motor unit action potentials (MUAP5) non-invasively, we invented 1) a brush-tip pin (BTP) electrode made of a bundle of fine wires for contacting the skin without electrolytic jelly; 2) a miniature active surface electrode array consisting of the BTP electrodes and signal buffers built into the device for sampling the MUAPs distributed on the skin; and 3) a surface EMG recording method which makes use of the bipolar electrode configuration for spatial filtering and the Hilbert transform for correcting for the phase-frequency non-linearity of the bipolar electrode transfer function. Based on these novel electrodes and recording method, the McSERCE system can be used to obtain MUAPs with high selectivity, resolution and signal-to-noise ratios. To extract individual MUAPs from EMG signals recorded on the skin with the McSERCE system, McSED, an effective, efficient, and robust multi-channel surface EMG decomposition method, was developed. The McSED method incorporates the following new techniques: 1) the detection of MUAPs using a multi-pass scheme which locates and matches action potentials detected simultaneously at slightly different locations on the skin; 2) the representation of MUAPs with their spatial distribution and temporal propagation patterns and times of occurrences; 3) the measurement of dissimilarity between MUAPs in terms of these patterns and times of occurrences; 4) the classification of MUAPs using both the “chaining” and the “dissection” characteristics of the single and complete linkage clustering methods, respectively; and 5) the estimation of the firing parameters of an incomplete MUAP train using a maximum-likelihood estimator. Using McSERCE and McSED, a clinical study was conducted on the MU conduction velocities of the abductor pollicis brevis muscle. Results showed that 2% of the 894 MUs detected in the muscles of 32 control subjects were “slow MUs” (v < 2.5 m/sec), whereas 27.7% of the 141 MUs detected in the muscles of four patients with myopathic disorders were slow MUs.

description: In this sequel to [1], we take up a second approach in bending the Bruhat-Tits tree. Inspired by the BTZ black hole connection, we demonstrate that one can transplant it to the Bruhat-Tits tree, at the cost of defining a novel "exponential function" on the p-adic numbers that is hinted by the BT tree. We demonstrate that the PGL$(2,Q_p)$ Wilson lines [2] evaluated on this analogue BTZ connection is indeed consistent with correlation functions of a CFT at finite temperatures. We demonstrate that these results match up with the tensor network reconstruction of the p-adic AdS/CFT with a different cutoff surface at the asymptotic boundary, and give explicit coordinate transformations that relate the analogue p-adic BTZ background and the "pure" Bruhat-Tits tree background. This is an interesting demonstration that despite the purported lack of descendents in p-adic CFTs, there exists non-trivial local Weyl transformations in the CFT corresponding to diffeomorphism in the Bruhat-Tits tree.

description: Globally symmetric spinor condensates in free space are argued not to support stable topological defects in either two or three dimensions.

A sufficient condition for the existence of Skyrmion solutions in three dimensions is formulated and illustrated in simple examples. Our results pertain to Bose-Einstein condensation in Rb.

description: The nucleus of Hen 2-428 is a short orbital period (4.2 h) spectroscopic binary, whose status as potential supernovae type Ia progenitor has raised some controversy in the literature. We present preliminary results of a thorough analysis of this interesting system, which combines quantitative non-local thermodynamic (non-LTE) equilibrium spectral modelling, radial velocity analysis, multi-band light curve fitting, and state-of-the art stellar evolutionary calculations. Importantly, we find that the dynamical system mass that is derived by using all available He II lines does not exceed the Chandrasekhar mass limit. Furthermore, the individual masses of the two central stars are too small to lead to an SN Ia in case of a dynamical explosion during the merger process.

The thesis begins by introducing to the reader the status of information in the modern era, which along with the technological evolution contributed to the development of this form of libraries. Following, an attempt is made to clarify the concept of digital library and to present examples of its operation. It outlines the relevant copyright legislative framework at domestic, community and international level by addressing specific issues of infringment on the operation of digital libraries. Moreover, specific legal interest issues related to digital libraries are being introduced. Such are the existence and protection of databases included in digital libraries, the management and protection of particular cases of orphan or οut of print works, the protection measures by means of technology, the digital rights management systems and the legal status of collective management of copyright. Finally, it tracks the modern trend of open access to digital content, the specific case of creative commons licenses along with their application to the example of digital repositories.

description: The recent measurements by CLEO Collaboration for the inclusive J/Psi and Psi(2S) production in Upsilon(1S) decay and our previous calculation are analyzed. The J/Psi momentum spectrum and the production ratio of Psi(2S) versus J/Psi favour Upsilon to J/Psi(Psi(2S)) + ccbar g as the dominant contribution. We point out that the differences between the experimental data and our previous results are mainly originated from the setting of the parameter charm quark mass. We further suggest the associate strange particle enhancement as a probe for the open charm particles in Upsilon to J/Psi (Psi(2S)) + ccbar g.

description: Direct measurements of the masses of supermassive black holes (SMBHs) are key to understanding their growth and constrain their symbiotic relationship to their host galaxies. However, current methods used to directly measure black hole masses in active quasars become challenging or impossible beyond $z\gtrsim0.2$. Spectroastrometry (SA) measures the spatial centroid of an object's spectrum as a function of wavelength, delivering angular resolution far better than the point-spread function (PSF) for high signal-to-noise ratio observations. We observed the luminous quasar SDSS J212329.47--005052.9 at $z=2.279$ with the aim of resolving its $\sim100μ\mathrm{as}$ H$α$ broad emission-line region (BLR), and present the first SA constraints on the size and kinematic structure of the BLR. Using a novel pipeline to extract the SA signal and reliable uncertainties, we achieved a centroiding precision of $\simeq100μ\mathrm{as}$, or $>2000\times$ smaller than the $K$-band AO-corrected PSF, yielding a tentative $3.2σ$ detection of an SA signal from the BLR. Modeling the BLR emission as arising from an inclined rotating disk with a mixture of coherent and random motions we constrain $r_\mathrm{BLR}=454^{+565}_{-162}\,μ\mathrm{as}$ ($3.71^{+4.65}_{-1.28}\,\mathrm{pc}$), providing a $95\%$ confidence upper limit on the black hole mass $M_\mathrm{BH}\,\sin^2\,i \leq1.8 \times10^9\,\mathrm{M}_\odot$. Our results agree with the $r_\mathrm{BLR}-L$ relation measured for lower-$z$ quasars, but expands its dynamic range by an order of magnitude in luminosity. We did not detect the potentially stronger SA signal from the narrow-line region, but discuss in detail why it may be absent. Already with existing instrumentation, SA can deliver $\sim6\times$ smaller uncertainties ($\sim15\,μ\mathrm{as}$) than achieved here, enabling $\sim10\%$ measurements of SMBH masses in high-$z$ quasars.

description: A financial market is called "diverse" if no single stock is ever allowed to dominate the entire market in terms of relative capitalization. In the context of the standard Ito-process model initiated by Samuelson (1965) we formulate this property (and the allied, successively weaker notions of "weak diversity" and "asymptotic weak diversity") in precise terms. We show that diversity is possible to achieve, but delicate. Several illustrative examples are provided, which demonstrate that weakly-diverse financial markets contain relative arbitrage opportunities: it is possible to outperform (or underperform) such markets over sufficiently long time-horizons, and to underperform them significantly over arbitrary time-horizons. The existence of such relative arbitrage does not interfere with the development of option pricing, and has interesting consequences for the pricing of long-term warrants and for put-call parity. Several open questions are suggested for further study.

description: Fawzi and Fawzi recently defined the sharp Rényi divergence, $D_α^\#$, for $α\in (1, \infty)$, as an additional quantum Rényi divergence with nice mathematical properties and applications in quantum channel discrimination and quantum communication. One of their open questions was the limit $α \to 1$ of this divergence. By finding a new expression of the sharp divergence in terms of a minimization of the geometric Rényi divergence, we show that this limit is equal to the Belavkin-Staszewski relative entropy. Analogous minimizations of arbitrary generalized divergences lead to a new family of generalized divergences that we call kringel divergences, and for which we prove various properties including the data-processing inequality.

description: Humus forms are a distinctive morphological indicator of soil organic matter decomposition. The spatial distribution of humus forms depends on environmental factors such as topography, climate and vegetation. In montane and subalpine forests, environmental influences show a high spatial heterogeneity, which is reflected by a high spatial variability of humus forms. This study aims at examining spatial patterns of humus forms and their dependence on the spatial scale in a high mountain forest environment (Val di Sole/Val di Rabbi, Trentino, Italian Alps). On the basis of the distributions of environmental covariates across the study area, we described humus forms at the local scale (six sampling sites), slope scale (60 sampling sites) and landscape scale (30 additional sampling sites). The local variability of humus forms was analyzed with regard to the ground cover type. At the slope and landscape scale, spatial patterns of humus forms were modeled applying random forests and ordinary kriging of the model residuals. The results indicate that the occurrence of the humus form classes Mull, Mullmoder, Moder, Amphi and Eroded Moder generally depends on the topographical position. Local-scale patterns are mostly related to micro-topography (local accumulation and erosion sites) and ground cover, whereas slope-scale patterns are mainly connected with slope exposure and elevation. Patterns at the landscape scale show a rather irregular distribution, as spatial models at this scale do not account for local to slope-scale variations of humus forms. Moreover, models at the slope scale perform distinctly better than at the landscape scale. In conclusion, the results of this study highlight that landscape-scale predictions of humus forms should be accompanied by local- and slope-scale studies in order to enhance the general understanding of humus form patterns.

description: Context. The discovery of an extrasolar planet with an ocean has crucial importance in the search for life beyond Earth. The polarimetric detection of specularly reflected light from a smooth liquid surface is anticipated theoretically, though the polarimetric signature of Earth's oceans has not yet been conclusively detected in disk-integrated planetary light. Aims. We aim to detect and measure the polarimetric signature of the Earth's oceans. Methods. We conducted near-infrared polarimetry for lunar Earthshine and collected data on 32 nights with a variety of ocean fractions in the Earthshine-contributing region. Results. A clear positive correlation was revealed between the polarization degree and ocean fraction. We found hourly variations in polarization in accordance with rotational transition of the ocean fraction. The ratios of the variation to the typical polarization degree were as large as ~0.2-1.4. Conclusions. Our observations provide plausible evidence of the polarimetric signature attributed to Earth's oceans. Near-infrared polarimetry may be considered a prospective technique in the search for exoplanetary oceans.

description: In this article we study the influence of magnetic fields on the axial gravitational waves emitted during the collapse of a homogeneous dust sphere. We found that while the energy emitted depends weakly on the initial matter perturbations it has strong dependence on the strength and the distribution of the magnetic field perturbations. The gravitational wave output of such a collapse can be up to an order of magnitude larger or smaller calling for detailed numerical 3D studies of collapsing magnetized configurations.

description: Recent research provides evidence for the socialisation of outgroup attitudes (i.e., prejudice) in friendship networks: Over time, individuals’ attitudes become more similar to their friends’ attitudes (Bracegirdle et al., 2022; Hjerm et al., 2018; la Roi et al., 2020; van Zalk et al., 2013; Zingora et al., 2020). But does socialisation lead to overall more or less prejudice? This question remains open because studies to date have not assessed the extent to which socialisation can drive prejudice in different directions. We will apply RSiena simulation models, a newly developed extension of longitudinal social network analysis, to assess the consequences of socialisation for the overall levels of prejudice in a network. We will quantify and compare the extent to which influence from low-, neutral- and high- prejudice individuals leads to changes in prejudice in the network, depending on individuals’ initial levels of prejudice.

description: We present the leading colour and light fermionic planar two-loop corrections for the production of two photons and a jet in the quark-antiquark and quark-gluon channels. In particular, we compute the interference of the two-loop amplitudes with the corresponding tree level ones, summed over colours and polarisations. Our calculation uses the latest advancements in the algorithms for integration-by-parts reduction and multivariate partial fraction decomposition to produce compact and easy-to-use results. We have implemented our results in an efficient C++ numerical code. We also provide their analytic expressions in Mathematica format.

description: The effects of space charges on hysteresis loops and field distributions in ferroelectrics have been investigated numerically using the phenomenological Landau-Ginzburg-Devonshire theory. Cases with the ferroelectric fully and partially depleted have been considered. In general, increasing the number of charged impurities results in a lowering of the polarization and coercive field values. Squarer loops were observed in the partially depleted cases and a method was proposed to identify fully depleted samples experimentally from dielectric and polarization measurements alone. Unusual field distributions found for higher dopant concentrations have some interesting implications for leakage mechanisms and limit the range of validity of usual semiconductor equations for carrier transport.

description: We present a comprehensive theory of the Dyakonov-Shur (DS) plasma instability in current-biased graphene transistors. Using the hydrodynamic approach, we derive equations describing the DS instability in the two-dimensional electron fluid in graphene at arbitrary values of electron drift velocity. These nonlinear equations together with Maxwell's equations are used for numerical analysis of the spatial and temporal evolution of the graphene electron system after the DS instability is triggered by random current fluctuations. We analyze conditions necessary for the onset of the DS instability and the properties of the final stationary state of the graphene electron system. We demonstrate that the instability results in the coherent anharmonic oscillatory state of the electron fluid and calculate both the spatial distribution and the power of the electromagnetic radiation generated by the graphene transistor in the DS instability regime.

description: Purpose: Language Impairment Testing in Multilingual Settings (LITMUS) instruments were developed to improve the identification of developmental language disorders in multilingual children. The current study investigated the usability and feasibility of the online Dutch version of several of these instruments (LITMUS-NL) according to speech-language pathologists (SLPs), thereby taking the first steps toward implementation in clinical practice.Method: We first conducted a usability study in which 24 SLPs performed the LITMUS-NL tests while using a think-aloud protocol. They subsequently filled out a questionnaire to investigate the degree of usability and added value of LITMUS-NL. After adapting LITMUS-NL based on the results of the usability study, a feasibility study was carried out in which 25 other SLPs each used LITMUS-NL with three multilingual children. Afterward, they completed a feasibility questionnaire and questionnaires about the reactions of the children.Results: In the first study, many usability issues emerged, mainly concerning technical problems, instructions, and test construction. Despite these issues, the SLPs evaluated the degree of usability and added value as positive. The feasibility study revealed a lower degree of usability and, despite the adaptations, feasibility issues in the same categories.Conclusions: By involving the intended users in the process toward implementing a new product, we identified (and solved) many issues that would interfere with successful implementation in daily clinical practice. A systematic, iterative approach toward implementation helps identify what is deemed important by the intended users of a new product and bridges the gap between research and practice.Supplemental Material S1.
