description: Modification of interatomic distances due to high pressure leads to exotic phenomena, including metallicity, superconductivity and magnetism, observed in materials not showing such properties in normal conditions. In two-dimensional crystals, such as graphene, atomic bond lengths can be modified by more that 10 percent by applying in-plane strain, i.e., without generating high pressure in the bulk. In this work, we study the strain-induced Mott transition on a honeycomb lattice by using computationally inexpensive techniques, including Gutzwiller Wave Function (GWF) and different variants of Gutzwiller Approximation (GA), obtaining the lower and upper bounds for critical Hubbard repulsion ($U$) of electrons. For uniaxial strain in the armchair direction the band gap is absent, and electron correlations play a dominant role. A significant reduction of the critical Hubbard $U$ is predicted. Model considerations are mapped onto tight-binding Hamiltonian for monolayer graphene by the auxiliary Su-Schrieffer-Heeger model for acoustic phonons, assuming zero stress in the direction perpendicular to the strain applied. Our results suggest that graphene, although staying in semimetallic phase even for extremely high uniaxial strains, may show measurable signatures of electron correlations, such as the band narrowing and the reduction of double occupancies.

description: We report the results of a long campaign of time-series photometry on the nova-like variable UX Ursae Majoris during 2015. It spanned 150 nights, with ~1800 hours of coverage on 121 separate nights. The star was in its normal `high state' near magnitude V=13, with slow waves in the light curve and eclipses every 4.72 hours. Remarkably, the star also showed a nearly sinusoidal signal with a full amplitude of 0.44 mag and a period of 3.680 +/- 0.007 d. We interpret this as the signature of a retrograde precession (wobble) of the accretion disc. The same period is manifest as a +/-33 s wobble in the timings of mid-eclipse, indicating that the disc's centre of light moves with this period. The star also showed strong `negative superhumps' at frequencies w_orb+N and 2w_orb+N, where w_orb and N are respectively the orbital and precession frequencies. It is possible that these powerful signals have been present, unsuspected, throughout the more than 60 years of previous photometric studies.

description: The ability to test and constrain theories of cosmic inflation will advance substantially over the next decade. Key data sources include cosmic microwave background (CMB) measurements and observations of the distribution of matter at low-redshift from optical, near-infrared, and 21cm intensity surveys. A positive detection of a CMB B-mode consistent with a primordial stochastic gravitational wave background (SGWB) is widely viewed as a smoking gun for an inflationary phase. Still, a null result does not exclude inflation. However, in a significant class of inflationary scenarios, a low SGWB amplitude is correlated with a more significant running, $α_s$, in the primordial density perturbations than is seen with the simplest inflationary potentials. With this motivation, we forecast the precision with which the spectral index $n_{\rm{s}}$ and $α_{\rm{s}}$ can be constrained by currently envisaged observations, including CMB (Simons Observatory, CMB-S4 and LiteBIRD), optical/near infra-red (DESI and SPHEREx), and 21cm intensity mapping (Tianlai and CHIME) surveys. We identify optimal combinations of datasets for constraining the running and show that they may yield additional and informative constraints on the overall inflationary parameter space if the SGWB remains undetected.

Agency problems, subsidiary staffing composition, and performance
Creators: name: Kim, Kyungjoong
Publisher: name: No Publisher Supplied
Year: 2022

description: Based on agency theory and institutional perspective, I argue that staffing composition in a foreign subsidiary reflects the aggregate effect of formal and informal institutions in the host country and that the composition affects subsidiary performance. The opportunism in agency relationships varies with the extent to which culture constrains the opportunistic behavior of local employees, and this, in turn, influences the staffing composition for headquarters to reduce agency costs in a subsidiary. Furthermore, I also argue that, although a high proportion of local employees outsourced from outside headquarters detrimentally affects its subsidiary performance, this negative relationship is moderated by the cultural characteristics of the host country which restrict the opportunistic behavior and goal-incongruence in work contracts. Lastly, the business group association of a parent firm contributes to increasing its subsidiary performance. In the first essay, I tested my arguments on a sample of 22,902 foreign subsidiaries of 4,253 Korean MNEs in 60 countries in 2012, 2014, and 2016. The second and third essays used a sample of 3,830 and 3,832 foreign subsidiaries of 475 Korean firms operating in 46 countries from 2011 to 2016.

Asymptotics of Some Plancherel Averages via Polynomiality Results

Subjects: subject: Combinatorics (math.CO)

description: Consider Young diagrams of $n$ boxes distributed according to the Plancherel measure. So those diagrams could be the output of the RSK algorithm, when applied to random permutations of the set $\{1,\ldots,n\}$. Here we are interested in asymptotics, as $n\to \infty$, of expectations of certain functions of random Young diagrams, such as the number of bumping steps of the RSK algorithm that leads to that diagram, the side length of its Durfee square, or the logarithm of its probability. We can express these functions in terms of hook lengths or contents of the boxes of the diagram, which opens the door for application of known polynomiality results for Plancherel averages. We thus obtain representations of expectations as binomial convolutions, that can be further analyzed with the help of Rice's integral or Poisson generating functions. Among our results is a very explicit expression for the constant appearing in the almost equipartition property of the Plancherel measure.

description: Here we study subwavelength gratings for coupling into graphene plasmons by means of an an- alytical model based on transformation optics that is not limited to very shallow gratings. We consider gratings that consist of a periodic modulation of the charge density in the graphene sheet, and gratings formed by this conductivity modulation together with a dielectric grating placed in close vicinity of the graphene. Explicit expressions for the dispersion relation of the plasmon po- laritons supported by the system, and reflectance and transmittance under plane wave illumination are given. We discuss the conditions for maximising the coupling between incident radiation and plasmons in the graphene, finding the optimal modulation strength for a conductivity grating.

description: This article explores the novel notion of gyrogroup actions, which is a natural generalization of the usual notion of group actions. As a first step toward the study of gyrogroup actions from the algebraic viewpoint, we prove three well-known theorems in group theory for gyrogroups: the orbit-stabilizer theorem, the orbit decomposition theorem, and the Burnside lemma (or the Cauchy-Frobenius lemma). We then prove that under a certain condition, a gyrogroup $G$ acts transitively on the set $G/H$ of left cosets of a subgyrogroup $H$ in $G$ in a natural way. From this we prove the structure theorem that every transitive action of a gyrogroup can be realized as a gyrogroup action by left gyroaddition. We also exhibit concrete examples of gyrogroup actions from the Möbius and Einstein gyrogroups.
Cosmogenesis as symmetry transformation

description: We consider the quantized bi-scalar gravity, which may serve as a locally Lorentz invariant cosmological model with varying speed of light and varying gravitational constant. The equation governing the quantum regime for the case of homogeneous and isotropic cosmological setup is a Dirac-like equation which replaces the standard Wheeler-DeWitt equation. We show that particular cosmogenesis may occur as a result of the action of the symmetry transformation which due to Wigner's theorem can either be unitary or antiunitary. We demonstrate that the transition from the pre-big-bang contraction to the post-big-bang expansion - a scenario that also occurs in string quantum cosmologies - can be attributed to the action of charge conjugation, which belongs to the class of antiunitary transformations. We also demonstrate that the emergence of the two classical expanding post-big-bang universe-antiuniverse pairs, each with opposite spin projections, can be understood as being triggered by the action of a unitary transformation resembling the Hadamard gate.

Using transmission electron microscopy together with energy dispersive x-ray spectra (which maps the element concentration across the BiFeO$_3$/Ag interface) and x-ray photoelectron spectroscopy, we show that both the observed specific self-assembly pattern of BiFeO$_3$ and Ag nanoparticles and the charge transfer between Ag and O are responsible for such an enormous rise in room-temperature magnetization. The BiFeO$_3$/Ag nanocomposites, therefore, could prove to be extremely useful for a variety of applications including biomedical.

description: A key unanswered question is how the settling rate of large particles is related to the rheology of the fluid and the local shear in the particle vicinity. In this study, a numerical investigation of large particle settling in un-sheared and sheared non-Newtonian fluids is presented. The particle settling rate increases with increasing imposed shear and with increasing shear thinning. For power-law and Herschel-Bulkley fluid rheology model, a criterion proposed for estimating the settling velocity under shear that can be used to provide estimates of particle settling under transport and the likely distance before complete stratification under laminar flow.

We define such a system space-temporal Sinai billiard We dis- cuss the problem in semiclassical approach. We show that in semiclassical regime the formation of trapped periodic semiclassical orbits inside the sys- tem is unavoidable. This leads to general expression of survival probabilities and scattering time delays, expanded to the chaotic Pollicott-Ruelle reso- nances. Finally, we comment on possible generalizations of these aspects to relativistic quantum field theory.

description: The fast electrical switching of electrical signals in an LED illumination bulb allows it to be used for both Visible Light Communication (VLC) and Visible Light Positioning (VLP). An indoor simple, fast, geometric positioning system called the Binary Search Algorithm which uses RSSI trilateration is introduced. It is robust against noise. When dealing with multipath light reflection issues the positioning accuracy ballooned from millimeters to meters. The photodetector Field-of-View minimization and error minimization algorithms are proposed reducing positioning errors to centimeters. This work guides the lighting engineer for the best installation of LED lamps by considering illumination and positioning criteria.

description: The complete quantum metric of a parametrized quantum system has a real part (usually known as the Provost-Vallee metric) and a symplectic imaginary part (known as the Berry curvature). In this paper, we first investigate the relation between the Riemann curvature tensor of the space described by the metric, and the Berry curvature, by explicit parallel transport of a vector in Hilbert space. Subsequently, we write a generating function from which the complex metric, as well as higher order geometric tensors (affine connection, Riemann curvature tensor) can be obtained in terms of gauge invariant cumulants. The generating function explicitly relates the quantities which characterize the geometry of the parameter space to quantum fluctuations. We also show that for a mixed quantum-classical system both real and imaginary parts of the quantum metric contribute to the dynamics, if the mass tensor is Hermitian. A many operator generalization of the uncertainty principle results from taking the determinant of the complex quantum metric. We also calculate the quantum metric for a number of Lie group coherent states, including several representations of the $SU(1,1)$ group. In our examples non-trivial complex geometry results for generalized coherent states. A pair of oscillator states corresponding to the $SU(1,1)$ group gives a double series for its spectrum. The two minimal uncertainty coherent states show trivial geometry, but, again, for generalized coherent states non-trivial geometry results.

description: In this PhD thesis the mechanical and microstructural properties of various FRPs when exposed to different harsh environments and used with concrete (i.e. seawater and sea sand concrete (SWSSC)) are investigated. To study the mechanical properties of several types of FRP under environmental conditions, different mechanical tests, including three-point bending, charpy impact, compression, tensile, split-disk, and push-out, were carried out. Moreover, to investigate the microstructural properties and degradation mechanisms, scanning electron microscopy (SEM) and micro computed tomography (micro- CT) analyses were conducted. Regression models (linear Bayesian regression) and long-term performance models (using Arrhenius law) were constructed to predict short-term and long-term mechanical properties of different FRPs under different conditions. Finally, reduction factors for different environments were proposed based on the experimental results and long-term performance models.

description: We simulate the time-dependent coherent dynamics of a spatially indirect exciton (an electron-hole pair with the two particles confined in different layers) in a GaAs coupled quantum well system. We use a unitary wave-packet propagation method taking into account in full the four degrees of freedom of the two particles in a two-dimensional system, including both the long-range Coulomb attraction and arbitrary two-dimensional electrostatic potentials affecting the electron and/or the hole separately. The method has been implemented for massively parallel architectures to cope with the huge numerical problem, showing good scaling properties and allowing evolution for tens of picoseconds. We have investigated both transient time phenomena and asymptotic time transmission and reflection coefficients for potential profiles consisting of i) extended barriers and wells and ii) a single-slit geometry. We found clear signatures of the internal two-body dynamics, with transient phenomena in the picosecond time-scale which might be revealed by optical spectroscopy. Exact results have been compared with mean-field approaches which, neglecting dynamical correlations by construction, turn out to be inadequate to describe the electron-hole pair evolution in realistic experimental conditions.

description: A single living biological cell is small in scale, but complex in structure. Various achievements have been fulfilled by microinjection process: injecting external particles at nanoscale into the living cells. This study investigates mechanical responses of biological cells being indented by atomic force microscope, from the cell’s deformation to the cell membrane disruption. The interactions between the living cell and the indenting probe are described by novelistically established models, and validated by experiments. The models established in this study illustrate the complex mechanical structure of the cell, furthering the understanding of the mechanical behaviour of the single cell during microinjection.

description: HfTe5 is predicted to be a promising platform for studying topological phases. Here through an electrical transport study, we present the first observation of chiral anomaly and ultrahigh mobility in HfTe5 crystals. Negative magneto-resistivity in HfTe5 is observed when the external magnetic and electrical fields are parallel (B//E) and quickly disappears once B deviates from the direction of E. Quantitative fitting further confirms the chiral anomaly as the underlying physics. Moreover, by analyzing the conductivity tensors of longitudinal and Hall traces, ultrahigh mobility and ultralow carrier density are revealed in HfTe5, which paves the way for potential electronic applications.

description: We propose a neuralized undirected graphical model called Neural-Hidden-CRF to solve the weakly-supervised sequence labeling problem. Under the umbrella of probabilistic undirected graph theory, the proposed Neural-Hidden-CRF embedded with a hidden CRF layer models the variables of word sequence, latent ground truth sequence, and weak label sequence with the global perspective that undirected graphical models particularly enjoy. In Neural-Hidden-CRF, we can capitalize on the powerful language model BERT or other deep models to provide rich contextual semantic knowledge to the latent ground truth sequence, and use the hidden CRF layer to capture the internal label dependencies. Neural-Hidden-CRF is conceptually simple and empirically powerful. It obtains new state-of-the-art results on one crowdsourcing benchmark and three weak-supervision benchmarks, including outperforming the recent advanced model CHMM by 2.80 F1 points and 2.23 F1 points in average generalization and inference performance, respectively.

Appearing in the transformation formulas are generalizations of Dedekind sums involving the periodic Bernoulli function. Reciprocity law is proved for periodic Apostol-Dedekind sum outside of the context of the transformation formulas. Furthermore, transformation formulas are presented for $G(z,s;A_α,I;r_{1},r_{2})$ and $G(z,s;I,A_{α};r_{1},r_{2})$, where $I=\left\{ 1\right\}$. As an application of these formulas, analogues of Ramanujan's formula for periodic zeta-functions are derived.

description: We present the results of an IR spectroscopic study of pyridine–water heterodimer formation in helium nanodroplets. The experiments were carried out in the frequency range of the pyridine C–H stretch region (3055–3100 cm−1) and upon water deuteration in the D–O stretch region (2740–2800 cm−1). In order to come to an unambiguous assignment we have determined the angle between the permanent dipole and the vibrational transition moment of the aggregates. The experiments have been accompanied by theoretical simulations which yielded two minimum structures with a 16.28 kJ mol−1energy difference. The experimentally observed bands were assigned to two structures with different H-bonds: an N⋯H bond and a bifurcated O⋯H–C bond.

The widely used linear observation model (with additive Gaussian noise) is combined with the linear spectral mixture model to form the likelihoods of the observations. The non-negativity and sum-to-one constraints resulting from the intrinsic physical properties of the abundances are introduced as prior information to regularize this ill-posed problem. The joint fusion and unmixing problem is then formulated as maximizing the joint posterior distribution with respect to the endmember signatures and abundance maps, This optimization problem is attacked with an alternating optimization strategy. The two resulting sub-problems are convex and are solved efficiently using the alternating direction method of multipliers. Experiments are conducted for both synthetic and semi-real data. Simulation results show that the proposed unmixing based fusion scheme improves both the abundance and endmember estimation comparing with the state-of-the-art joint fusion and unmixing algorithms.

description: We analyze in detail the possibility to use charge-dipole interaction between a single polar molecule or a 1D molecular array and a single Rydberg atom to read out rotational populations. The change in the Rydberg electron energy is conditioned on the rotational state of the polar molecules, allowing for realization of a CNOT quantum gate between the molecules and the atom. Subsequent readout of the atomic fluorescence results in a non-destructive measurement of the rotational state. We study the interaction between a 1D array of polar molecules and an array or a cloud of atoms in a Rydberg superatom (blockaded) state and calculate the resolved energy shifts of Rb(60s) with KRb and RbYb molecules, with N=1, 3, 5 molecules. We show that collective molecular rotational states can be read out using the conditioned Rydberg energy shifts.

description: We have investigated the boson sector in an extended standard model (SM) with additional $U(1)_D$ symmetry. In the proposed model, the singlet scalar and doublet scalar Higgs are added in addition to the SM-like scalar Higgs. These scalars are also coupled to the gauge boson fields. In this work, we calculate the masses of both gauge and scalar Higgs bosons. Their masses are obtained through spontaneous symmetry breaking using the Higgs fields with non-zero vacuum expectation values. We also study numerically the positivity conditions of the vacuum expectation value of the scalars. In particular, we perform scanning of the parameter space of the potential and study the obtained scalar mass dependence on the parameter of the model.

description: We report high-resolution inelastic x ray scattering measurements of the acoustic phonons of URu2Si2. We observe minimal change in the phonon structure upon entering the Hidden Order phase. At all temperatures, the longitudinal acoustic phonons are anomalously broad at low q. There is no evidence to suggest that the increase in thermal conductivity in the Hidden Order phase is driven by a change in phonon dispersions or lifetimes. A more likely explanation is that the magnetic excitations in the Hidden Order state contribute to thermal transport.

description: While intermittent streams are distributed all around the world, there has been little focus on protecting them and understanding their hydrological behaviour. I developed a spatially distributed hydrological model of rural catchments with intermittent streamflow in south-west of Victoria. I applied the model to assess the impacts of rainfall frequency and land-use change on the water balance of seasonally dry regions. My study shows the important relationships between catchment topography and location of afforested areas, questioning the use of simple lumped models for the implementation of regulations to manage intermittent catchments.

description: Diapria apicalis Walker, 1860: 359.
Valid name
Trichopria walkeri (Dalla Torre, 1890) comb. nov.
Summary of types
Syntype ♀, BMNH number 9.895.
Primary type data
63-52; apicalis; Diapria.
Type locality
Sri Lanka (as Ceylon).
Remarks
The syntype is mounted on a card and is entire. The number 63-52 refers to Natural History Museum Entomology register number 1863-52, which includes a group of insects described as “Type specimens described by Mr Walker in the Annuals & Magazine for 1858-59 -60”. Diapria apicalis was renamed Diapria walkeri by Dalla Torre (1890) because of homonymy with Diapria apicalis (Say 1836). The type of D. apicalis is a Trichopria so Trichopria walkeri is a new combination.

description: Hydrides are simple compounds containing one or a few hydrogen atoms bonded to a heavier atom. They are fundamental precursor molecules in cosmic chemistry and many hydride ions have become observable in high quality for the first time thanks to the Herschel Space Observatory. Ionized hydrides, such as CH+ and OH+, and also HCO+ that affect the chemistry of molecules such as water, provide complementary information on irradiation by far UV (FUV) or X-rays and gas temperature. The targeted lines of CH+, OH+, H2O+, C+ and CH are detected mostly in blue-shifted absorption. H3O+ and SH+ are detected in emission and only toward some high-mass objects. The observed line parameters and correlations suggest two different origins, related to gas entrained by the outflows and to the circumstellar envelope. The column density ratios of CH+/OH+ are estimated from chemical slab models, assuming that the H2 density is given by the specific density model of each object at the beam radius. For the low-mass YSOs the observed ratio can be reproduced for an FUV flux of 2-400 times the ISRF at the location of the molecules. In two high-mass objects, the UV flux is 20-200 times the ISRF derived from absorption lines, and 300-600 ISRF using emission lines. If the FUV flux required for low-mass objects originates at the central protostar, a substantial FUV luminosity, up to 1.5 L_sun, is required. There is no molecular evidence for X-ray induced chemistry in the low-mass objects on the observed scales of a few 1000 AU. For high-mass regions, the FUV flux required to produce the observed molecular ratios is smaller than the unattenuated flux expected from the central object(s) at the Herschel beam radius. This is consistent with an FUV flux reduced by circumstellar extinction or by bloating of the protostar.

description: Everything is in motion. "Inertness" arises from (approximative) repetition, that is, through rotation or an alternation that delineates a focus of consciousness.
This focus of consciousness, in turn, must also move/alternate (the two differ only in continuity). If its alternation seems to go too far - physically, psychically or intellectually - it reaches into the subconscious.
In this way, interconnection is established by the alternation of the focus of consciousness. Therefore, in a world in which everything is interconnected, all focuses must reciprocally transition into each other.
"Reality" is a common "goal", a focus which all participants can switch into and which is conscious to them as such, as a potential one. Its "degree of reality" is the probability of its fully becoming conscious (or more simply: its current degree of consciousness).
Thus, a reality is created when all participants increase its probability or, respectively, their consciousness of it. Published in: Journal of Consciousness Exploration & Research (2011), 2(6), p.877-884.

description: A quantum Hall edge state provides a rich foundation to study electrons in 1-dimension (1d) but is limited to chiral propagation along a single direction. Here, we demonstrate a versatile platform to realize new 1d systems made by combining quantum Hall edge states of opposite chiralities in a graphene electron-hole bilayer. Using this approach, we engineer helical 1d edge conductors where the counterpropagating modes are localized in separate electron and hole layers by a tunable electric field. These helical conductors exhibit strong nonlocal transport signals and suppressed backscattering due to the opposite spin polarizations of the counterpropagating modes. Moreover, we investigate these electron-hole bilayers in the fractional quantum Hall regime, where we observe conduction through fractional and integer edge states of opposite chiralities, paving the way towards the realization of 1d helical systems with fractional quantum statistics.

description: This thesis presents the experimental and theoretical investigations of rock dynamic splitting containing weak interfaces in the aim of understanding the failure mechanism of inhomogeneous rock. Two processes, a dynamically propagating crack interaction with a pre-existing weak bedding or grain/inclusion boundary and the local splitting around a grain/inclusion induced by dynamic tension, are respectively studied from the perspective of crack propagation in this interface-containing rock structure. This research reveals the intrinsic mechanism of heterogeneous rock fracturing under dynamic tension, with broad applications to rock blasting, fault zone pulverisation, and rock mass failure under dynamic loading.

description: The empirical spectra and $E2$ decay rates in $^{110,112,114,116}$Cd are shown to be consistent with a vibrational interpretation for low-lying normal states, coexisting with a single deformed $γ$-soft band of intruder states. The observed deviations from this paradigm show up in particular non-yrast states, which are properly described by a Hamiltonian with U(5) partial dynamical symmetry. The latter is characterized by a good (broken) symmetry in most (in selected) normal states, weakly coupled to intruder states.
