description: Enabling on-demand control of heat flow is key for the development of next-generation electronic devices, solid-state heat pumps, and thermal logic. However, precise and agile tuning of the relevant microscopic material parameters for adjusting thermal conductivities remains elusive. Here, we study several single crystals of lanthanum aluminate (LaAlO$_{3}$) with different domain structures and show that ferroelastic domain walls behave as boundaries that act like efficient controllers to govern thermal conductivity. At low temperature (3 K), we demonstrate a fivefold reduction in thermal conductivity induced by domain walls orthogonal to the heat flow and a twofold reduction when they are parallel to the heat flow. Atomistic calculations fully support this experimental observation. By breaking down phonon scattering mechanisms, we also analyze the temperature dependence of the thermal conductivity to derive a quantitative relation between thermal conductivity variations and domain wall organization and density.

description: In this paper, we develop a Markovian model that deals with the volume offered at the best quote of an electronic order book. The volume of the first limit is a stochastic process whose paths are periodically interrupted and reset to a new value, either by a new limit order submitted inside the spread or by a market order that removes the first limit. Using applied probability results on killing and resurrecting Markov processes, we derive the stationary distribution of the volume offered at the best quote. All proposed models are empirically fitted and compared, stressing the importance of the proposed mechanisms.

description: We propose a novel non-negative spherical relaxation for optimization problems over binary matrices with injectivity constraints, which in particular has applications in multi-matching and clustering. We relax respective binary matrix constraints to the (high-dimensional) non-negative sphere. To optimize our relaxed problem, we use a conditional power iteration method to iteratively improve the objective function, while at same time sweeping over a continuous scalar parameter that is (indirectly) related to the universe size (or number of clusters). Opposed to existing procedures that require to fix the integer universe size before optimization, our method automatically adjusts the analogous continuous parameter. Furthermore, while our approach shares similarities with spectral multi-matching and spectral clustering, our formulation has the strong advantage that we do not rely on additional post-processing procedures to obtain binary results. Our method shows compelling results in various multi-matching and clustering settings, even when compared to methods that use the ground truth universe size (or number of clusters).

A resonance feature in the $hh$ invariant mass is a smoking gun of an $s$-channel heavy Higgs resonance, $H$. With one $h$ decaying to two photons and the other decaying to $b$-quarks, the resonant signal may be discoverable above the $hh$ continuum background for $M_H

description: It is shown that for the one-dimensional quantum anharmonic oscillator with potential $V(x)= x^2+g^2 x^4$ the Perturbation Theory (PT) in powers of $g^2$ (weak coupling regime) and the semiclassical expansion in powers of $\hbar$ for energies coincide. It is related to the fact that the dynamics in $x$-space and in $(gx)$-space corresponds to the same energy spectrum with effective coupling constant $\hbar g^2$. Two equations, which govern the dynamics in those two spaces, the Riccati-Bloch (RB) and the Generalized Bloch (GB) equations, respectively, are derived. The PT in $g^2$ for the logarithmic derivative of wave function leads to PT (with polynomial in $x$ coefficients) for the RB equation and to the true semiclassical expansion in powers of $\hbar$ for the GB equation, which corresponds to a loop expansion for the density matrix in the path integral formalism. A 2-parametric interpolation of these two expansions leads to a uniform approximation of the wavefunction in $x$-space with unprecedented accuracy $\sim 10^{-6}$ locally and unprecedented accuracy $\sim 10^{-9}-10^{-10}$ in energy for any $g^2 \geq 0$. A generalization to the radial quartic oscillator is briefly discussed.

Geminates, the OCP and the Nature of CON
Creators: name: Keer, Edward W.
Publisher: name: No Publisher Supplied
Year: 1999

description: This dissertation is concerned with the Obligatory Contour Principle (OCP) and its relationship to the representation of geminate consonants. The OCP blocks lexical forms with pair geminates, a pair of adjacent identical melodies. Therefore geminates must be represented as single melodies associated to two timing units. The OCP is also active on outputs, blocking phonology from creating pair geminates. The dual nature of the OCP (as both input and output constraint) is derived from the interaction of ranked and violable output constraints in an Optimality-theoretic grammar. In this analysis, no input restrictions are required. The OCP is interpreted as a constraint on the set of constraints in UG (CON). The lexical OCP is accounted for by positing that no faithfulness constraint requires maintaining a distinction between one segment and two identical adjacent segments. The output OCP is accounted for by positing that output markedness constraints universally prefer one segment to two. The interaction of these markedness and faithfulness constraints neutralizes the contrast between pair and single geminates. One consequence of the analysis is that no specific OCP constraint is required. Rather, the effects of the OCP follow from general markedness considerations. Geminates behave differently with respect to phonological changes compared to their singleton counterparts. Geminates are sometimes affected by changes that affect singletons (alterability). Examples of geminate alterability are found in Faroese, Persian, Fula, and Alabama. The fission of geminates appears to be a counter example to the claim that markedness universally prefers one segment to two. It is shown that fission follows from the activity of faithfulness constraints relativized to the syllable onset. The analysis of fission captures an asymmetry in fission processes. No fission process creates a cluster where the initial segment is more faithful to the input than second segment. In addition to alterability, geminates are sometimes unaffected by changes that affect singletons (inalterability). Examples of geminate inalterability include Tiberian Hebrew, Latin, and the restriction of coda consonants in many languages. Universal inalterability must be an effect of the constraint responsible for the change in singletons. Parochial inalterability however, is the result of standard constraint interaction in an OT grammar.

description: As one of targets of many flux monitoring campaigns, the FSRQ 0507+179 shows various flux variation properties at almost all observing wavelengths, from radio to $γ$-ray. With Urumqi 25-m telescope, our study on this object is focusing on its radio flux variability, especially the Intra-Day Variability (IDV). We carried out a total of six epochs of IDV observations on 0507+179 at 4.8 GHz since Mar. 2010, found clearly IDV behaviors in all observing sessions and consider it is likely a type I IDV source by analyzing the characteristics and the timescales of the light curves. Additionally, we found 0507+179 exhibited some different IDV behaviors after an optical flare.

description: KA1858+4850 is a narrow-line Seyfert 1 galaxy at redshift 0.078 and is among the brightest active galaxies monitored by the Kepler mission. We have carried out a reverberation mapping campaign designed to measure the broad-line region size and estimate the mass of the black hole in this galaxy. We obtained 74 epochs of spectroscopic data using the Kast Spectrograph at the Lick 3-m telescope from February to November of 2012, and obtained complementary V-band images from five other ground-based telescopes. We measured the H-beta light curve lag with respect to the V-band continuum light curve using both cross-correlation techniques (CCF) and continuum light curve variability modeling with the JAVELIN method, and found rest-frame lags of lag_CCF = 13.53 (+2.03, -2.32) days and lag_JAVELIN = 13.15 (+1.08, -1.00) days. The H-beta root-mean-square line profile has a width of sigma_line = 770 +/- 49 km/s. Combining these two results and assuming a virial scale factor of f = 5.13, we obtained a virial estimate of M_BH = 8.06 (+1.59, -1.72) x 10^6 M_sun for the mass of the central black hole and an Eddington ratio of L/L_Edd ~ 0.2. We also obtained consistent but slightly shorter emission-line lags with respect to the Kepler light curve. Thanks to the Kepler mission, the light curve of KA1858+4850 has among the highest cadences and signal-to-noise ratios ever measured for an active galactic nucleus; thus, our black hole mass measurement will serve as a reference point for relations between black hole mass and continuum variability characteristics in active galactic nuclei.

description: In this paper we develop the analytical framework for a novel Wireless signal-based Sensing capability for Robotics (WSR) by leveraging robots' mobility. It allows robots to primarily measure relative direction, or Angle-of-Arrival (AOA), to other robots, while operating in non-line-of-sight unmapped environments and without requiring external infrastructure. We do so by capturing all of the paths that a wireless signal traverses as it travels from a transmitting to a receiving robot in the team, which we term as an AOA profile. The key intuition behind our approach is to enable a robot to emulate antenna arrays as it moves freely in 2D and 3D space. The small differences in the phase of the wireless signals are thus processed with knowledge of robots' local displacement to obtain the profile, via a method akin to Synthetic Aperture Radar (SAR). The main contribution of this work is the development of i) a framework to accommodate arbitrary 2D and 3D motion, as well as continuous mobility of both signal transmitting and receiving robots, while computing AOA profiles between them and ii) a Cramer-Rao Bound analysis, based on antenna array theory, that provides a lower bound on the variance in AOA estimation as a function of the geometry of robot motion. We show that allowing robots to use their full mobility in 3D space while performing SAR, results in more accurate AOA profiles and thus better AOA estimation. All analytical developments are substantiated by extensive simulation and hardware experiments on air/ground robot platforms using 5 GHz WiFi. Our experimental results bolster our analytical findings, demonstrating that 3D motion provides enhanced and consistent accuracy, with total AOA error of less than 10 degree for 95% of trials. We also analytically characterize the impact of displacement estimation errors on the measured AOA.

A Generally Covariant Theory of Quantized Dirac Field in de Sitter Spacetime

description: As a sequel to our previous work\cite{Feng2020}, we propose in this paper a quantization scheme for Dirac field in de Sitter spacetime. Our scheme is covariant under both general transformations and Lorentz transformations. We first present a Hamiltonian structure, then quantize the field following the standard approach of constrained systems. For the free field, the time-dependent quantized Hamiltonian is diagonalized by Bogliubov transformation and the eigen-states at each instant are interpreted as the observed particle states at that instant. The measurable energy-momentum of observed particle/antiparticles are the same as obtained for Klein-Gordon field. Moreover, the energy-momentum also satisfies geodesic equation, a feature justifying its measurability. As in \cite{Feng2020}, though the mathematics is carried out in terms of conformal coordinates for the sake of convenience, the whole theory can be transformed into any other coordinates based on general covariance. It is concluded that particle/antiparticle states, such as vacuum states in particular are time-dependent and vacuum states at one time evolves into non-vacuum states at later times. Formalism of perturbational calculation is provided with an extended Dirac picture.

Harmony, Dominance and Control
Creators: name: Bakovic, Eric
Publisher: name: No Publisher Supplied
Year: 2000

description: In this dissertation I argue for a general model of assimilation within Optimality Theory, with vowel harmony processes serving as a specific empirical testing ground. The model centers around agreement constraints. I demonstrate that the interaction among agreement constraints and other well-established constraints (particular members of the general markedness and faithfulness constraint families) is sufficient to account for the various vagaries of vowel harmony, and that representational devices such as crucial underspecification and autosegmental feature-sharing are consequently unnecessary. Vowel harmony processes can be either stem-controlled or dominant-recessive. Stem-controlled vowel harmony processes are the more familiar kind, where the harmonic feature value of vowels in the stem determines the harmonic feature value of vowels in subsequent affixes. In a language with a dominant-recessive vowel harmony process, on the other hand, one harmonic feature value is 'dominant' and the other is 'recessive' such that any dominant-valued morpheme vowel, stem or affix, determines the harmonic feature value of all other (otherwise recessive-valued) morpheme vowels. I offer a novel analysis of the distinction between stem-controlled and dominant-recessive vowel harmony processes. I argue that the phenomenon of stem control is due to the relatively higher rank of faithfulness constraints on the correspondence relation between stems and their affixed forms; i.e., that stem-controlled vowel harmony is a cyclic process. Dominance, on the other hand, is due to the relatively higher rank of a constraint that specifically prevents dominant-valued (here understood as 'unmarked') segments from becoming recessive-valued ('marked'). I argue that this type of constraint, a local conjunction of markedness and faithfulness, is independently required in order to explain the fact that a larger number of segments with a particular value of the harmonic feature do not ever "gang up" on a smaller number of segments with the opposite value, a universal fact that has otherwise proven to be difficult to guarantee as a general result. The factorial typology of the constraints relevant to the proposed model is thoroughly investigated, and several challenging examples (Yoruba, Maasai, Turkana and Nez Perce) are given detailed attention and analysis. Taken together, these components of the dissertation confirm the descriptive and explanatory adequacy of the proposed model.

description: The paper aims at developing the Bayesian seasonally cointegrated model for quarterly data. We propose the prior structure, derive the set of full conditional posterior distributions, and propose the sampling scheme. The identification of cointegrating spaces is obtained \emph{via} orthonormality restrictions imposed on vectors spanning them. In the case of annual frequency, the cointegrating vectors are complex, which should be taken into account when identifying them. The point estimation of the cointegrating spaces is also discussed. The presented methods are illustrated by a simulation experiment and are employed in the analysis of money and prices in the Polish economy.

description: We present in this paper a theoretical and numerical analysis of bending waves localized on the boundary of a platonic crystal whose building blocks are split ring resonators (SRR). We first derive the homogenized parameters of the structured plate using a three-scale asymptotic expansion in the linearized biharmonic equation. In the limit when the wavelength of the bending wave is much larger than the typical heterogeneity size of the platonic crystal, we show that it behaves as an artificial plate with an anisotropic effective Young modulus and a dispersive effective mass density. We then analyze dispersion diagrams associated with bending waves propagating within an infinite array of SRR, for which eigen-solutions are sought in the form of Floquet-Bloch waves. We finally demonstrate that this structure displays the hallmarks of All-Angle-Negative-Refraction(AANR) and it leads to superlensing and ultrarefraction effects, interpreted thanks to our homogenization model as a consequence of negative and vanishing effective density, respectively.

If an element of $R$ belongs to $h(R)=\cup _{α\in G}R_{α}$, then it is called a homogeneous. A Left $R$-module $M$ is said to be \textit{a graded }$R$\textit{-module} if there exists a family of additive subgroups $\{M_{α}\}_{α\in G}$ of $M$ such that $% M=\bigoplus_{α\in G}M_{α}$ and $R_{α}M_{β}\subseteq M_{αβ}$ for all $α,β\in G.$ Also if an element of $M$ belongs to $\cup _{α\in G}M_{α}=h(M)$, then it is called a homogeneous. A submodule $N$ of $M$ is said to be \textit{a graded submodule of }$M$ if $N=\bigoplus_{α\in G}(N\cap M_{α}):=\bigoplus_{α\in G}N_{α}$. Let $G$ be a group with identity $e$. Let $R$ be a $G$% -graded commutative ring and $M$ a graded $R$-module. A proper graded submodule $S$ of $M$ is said to be \textit{a graded semiprime (}shortly $gr$% \textit{-semiprime) submodule} if whenever $r^{n}m\in S$ where $r\in h(R)$, $% m\in h(M)$ and $n\in Z^{+}$, then $rm\in S.$ In this work, we introduce the concept of graded quasi-semiprime (shortly $gr$-quasi-semiprime) submodule as a generalization of $gr$-semiprime submodule and give some basic properties of these classes of graded submodules. We say that a proper graded submodule $S$ of $M$ is a $gr$-quasi-semiprime submodule if $% (S:_{R}M)=\{r\in R:rM\subseteq S\}$ is a $gr$-semiprime ideal of $R$.
Theoretical Aspects of Panoan Metrical Phonology: Disyllabic Footing and Contextual Syllable Weight
Creators: name: Ulloa, Jose A. Elias
Publisher: name: No Publisher Supplied
Year: 2006

description: This dissertation studies the relation between foot size and contextual syllable-weight. In particular, it focuses on the influence that foot disyllabicity has on triggering quantity adjustments of syllable weight. Within Optimality Theory (Prince and Smolensky 1993; 2004), this dissertation formally addresses the relation between foot size and syllable weight through the stringency relation between two constraints: *FOOT(syllable) and *FOOT(mora). The former penalizes feet smaller than two syllables and the latter, feet smaller than two moras. In isolation, they create a scale in which disyllabic feet are more preferable than monosyllabic feet and, in turn, bimoraic monosyllabic feet (symbolized as (H)-feet) are more preferable than monomoraic monosyllabic feet (symbolized as (L)-feet). The existence of other conflicting constraints can, however, prevent the occurrence of disyllabic feet, which in turn causes the emergence of monosyllabic feet. Whether feet are disyllabic or monosyllabic in a given context depends on the conflict between respecting the constraints that inhibit quantity adjustments, complying with those that restrict the distribution of syllable weight and satisfying the constraints *FOOT(syllable) and *FOOT(mora). Empirically, the relation between foot disyllabicity and quantity adjustments of syllable weight is studied through the detailed examination of two Panoan languages spoken in the Peruvian Amazon: Shipibo and Capanahua. The data presented is the result of several field trips carried out by the author. Although both languages are trochaic by default and distinguish heavy versus light syllables, (H)-feet are avoided in favor of disyllabic feet. In order to obtain disyllabic feet and avoid heavy syllables as heads of uneven (H.L)-trochees or in unstressed positions, Shipibo and Capanahua contextually adjust vowel length and the weight of closed syllables. The disyllabic footing of Shipibo and Capanahua is not only supported by the distribution of heads within the Prosodic Word (PrWd) but also by a number of segmental rhythmic phenomena; for example, rhythmic allomorphy, long vowels and heavy closed syllables restricted to even syllables, inhibition of glottal coalescence in odd syllables.

description: Entanglement swapping at telecom wavelengths is at the heart of quantum networking in optical fiber infrastructures. Although entanglement swapping has been demonstrated experimentally so far using various types of entangled photon sources both in near-infrared and telecom wavelength regions, the rate of swapping operation has been too low to be applied to practical quantum protocols, due to limited efficiency of entangled photon sources and photon detectors. Here we demonstrate drastic improvement of the efficiency at telecom wavelength by using two ultra-bright entangled photon sources and four highly efficient superconducting nanowire single photon detectors.We have attained a four-fold coincidence count rate of 108 counts per second, which is three orders higher than the previous experiments at telecom wavelengths. A raw (net) visibility in a Hong-Ou-Mandel interference between the two independent entangled sources was 73.3 $\pm$ 1.0% (85.1 $\pm$ 0.8%). We performed the teleportation and entanglement swapping, and obtained a fidelity of 76.3% in the swapping test.Our results on the coincidence count rates are comparable with the ones ever recorded in teleportation/swaping and multi-photon entanglement generation experiments at around 800\,nm wavelengths. Our setup opens the way to practical implementation of device-independent quantum key distribution and its distance extension by the entanglement swapping as well as multi-photon entangled state generation in telecom band infrastructures with both space and fiber links.

In this paper we focus on decentralized approaches able to provide adaptability to different infrastructural and traffic conditions. We formalize an Emergent Behavior Approach that, as per our knowledge, has never been performed for this purpose, and a Decentralized Auction approach. We compare them against existing centralized negotiation approaches based on auctions and we determine under which conditions each approach is preferable to the others.

description: This paper provides a dendriform-tree setting for Fliess operators with matrix-valued inputs. This class of analytic nonlinear input-output systems is convenient, for example, in quantum control. In particular, a description of such Fliess operators is provided using planar binary trees. Sufficient conditions for convergence of the defining series are also given.

description: We study fixed loci of antisymplectic involutions on projective hyperkähler manifolds of $\mathrm{K3}^{[n]}$-type. When the involution is induced by an ample class of square 2 in the Beauville-Bogomolov-Fujiki lattice, we show that the number of connected components of the fixed locus is equal to the divisibility of the class, which is either 1 or 2.

description: We present a fluorescence-lifetime based method for monitoring cell and tissue activity in situ, during cell culturing and in the presence of a strong autofluorescence background. The miniature fiber-optic probes are easily incorporated in the tight space of a cell culture chamber or in an endoscope. As a first application we monitored the cytosolic calcium levels in porcine tracheal explant cultures using the Calcium Green-5N (CG5N) indicator. Despite the simplicity of the optical setup we are able to detect changes of calcium concentration as small as 2.5 nM, with a monitoring time resolution of less than 1 s.

description: This thesis investigates the impact internationalisation has on environmental politics. Increases in the prevalence of environmental issues in politics have occurred across countries as internationalisation has intensified, yet most explanations for this focus on domestic factors. Investigating political parties across 34 countries over six decades, this thesis assesses the extent to which parties prioritise environmental issues in their election manifestos. It reveals that internationalisation contributes to parties paying more attention to environmental issues, demonstrating the relevance of external forces, and revealing that internationalisation might lead to more responsible and just forms of international cooperation and action on environmental crises.

Anomalous sound attenuation in Weyl semimetals in magnetic and pseudomagnetic fields

description: We evaluate the sound attenuation in a Weyl semimetal subject to a magnetic field or a pseudomagnetic field associated with a strain. Due to the interplay of intra- and inter-node scattering processes as well as screening, the fields generically reduce the sound absorption. A nontrivial dependence on the relative direction of the magnetic field and the sound wave vector, i.e., the magnetic sound dichroism, can occur in materials with nonsymmetric Weyl nodes (e.g., different Fermi velocities and/or relaxation times). It is found that the sound dichroism in Weyl materials can also be activated by an external strain-induced pseudomagnetic field. In view of the dependence on the field direction, the dichroism may lead to a weak enhancement of the sound attenuation compared with its value at vanishing fields.

description: Combinatorial optimization is a well-established area in operations research and computer science. Until recently, its methods have focused on solving problem instances in isolation, ignoring that they often stem from related data distributions in practice. However, recent years have seen a surge of interest in using machine learning, especially graph neural networks (GNNs), as a key building block for combinatorial tasks, either directly as solvers or by enhancing exact solvers. The inductive bias of GNNs effectively encodes combinatorial and relational input due to their invariance to permutations and awareness of input sparsity. This paper presents a conceptual review of recent key advancements in this emerging field, aiming at optimization and machine learning researchers.

description: In this paper, a new approach is presented to predict the crack growth path in the rock materials by taking into account the size effect. The proposed approach is an incremental method in which the crack initiation angle for each step is determined from the modified forms of the maximum tangential stress criterion. These modified maximum tangential stress criteria take into account the influence of the higher order terms of the stress series at the crack tip in addition to the singular terms. As an important parameter in the proposed method, the critical distance rc is also assumed to be size dependent. Finally the incremental method is evaluated by experimental results obtained from Guiting limestone and Ghorveh marble specimens reported in the previous studies. It is shown that the proposed approach can predict the fracture trajectory of cracked specimens with different sizes in good agreement with the experimental results when three terms of Williams series expansion are considered for characterizing the stress field around the crack tip.

description: The elucidation of fundamental mechanisms underlying ion-induced radiation damage of biological systems is crucial for the advancement of radiotherapy with ion beams and for radiation protection in space. The study of ion-induced biodamage using the phenomenon-based MultiScale Approach to the physics of radiation damage with ions (MSA) has led to the prediction of nanoscale shock waves (SW) that are created by ions in the biological medium at the high linear energy transfer (LET). The high-LET regime corresponding to energy losses higher than 1 keV/nm is typical for ions heavier than carbon in biological media at the Bragg peak region. This paper reveals that the thermomechanical stress of the DNA molecule by the ion-induced SW becomes the dominant mechanism of complex DNA damage at the high-LET ion irradiation. Damage of the DNA molecule in water caused by the ion-induced SW is studied by means of reactive molecular dynamics simulations. Five projectile ions (C, O, Si, Ar, and Fe) at the Bragg peak energies are considered. Simulations reveal that Ar and, especially, Fe ions induce multiple bond breakages in a DNA segment containing 20 base pairs. The DNA damage produced in segments of such size leads to complex irreparable lesions in a cell. This makes the SW-induced thermomechanical stress the dominant mechanism of complex DNA damage at the high-LET ion irradiation. A detailed theory for evaluating the DNA damage caused by ions at high-LET is formulated and integrated into the MSA formalism. The theoretical analysis reveals that a single ion hitting a cell nucleus at high-LET is sufficient to produce highly complex, lethal damages to a cell by the SW-induced thermomechanical stress. A good agreement of the calculated cell survival probabilities with experimental data obtained for the cell irradiation with iron ions provides strong experimental evidence of the ion-induced SW effect.

description: Mixed mode I/III behavior of Perspex (polymethyl methacrylate (PMMA)) is studied experimentally and theoretically in this research using a new and simple laboratory test configuration. The specimen is a circular disc containing a sharp V-notch along the diameter that is loaded by the conventional three-point bend fixture. The critical values of notch stress intensity factors (KjV and Кщ) were obtained for the whole combinations of modes I and III simply by changing the notch inclination angle relative to the loading rollers. The value of notch fracture toughness under pure or dominantly tension loads was greater than its corresponding value under mode III or dominantly torsion loads. The experimental results were also predicted very well by employing the local strain energy density (SED) criterion.

description: In this paper we study parametric TraceFEM and parametric SurfaceFEM (SFEM) discretizations of a surface Stokes problem. These methods are applied both to the Stokes problem in velocity-pressure formulation and in stream function formulation. A class of higher order methods is presented in a unified framework. Numerical efficiency aspects of the two formulations are discussed and a systematic comparison of TraceFEM and SFEM is given. A benchmark problem is introduced in which a scalar reference quantity is defined and numerically determined.
