Quantum theory of the real and the complexified projective line
Creators: name: Leitenberger, Frank
Publisher: name: arXiv
Year: 2005
Subjects: subject: Quantum Algebra (math.QA)
subject: FOS: Mathematics

description: Quantum deformations of sets of points of the real and the complexified projective line are constructed. These deformations depend on the deformation parameter q and certain further parameters λ_{ij}. The deformations for which the subspace of polynomials of degree three has a basis of ordered monomials are selected. We show that the corresponding algebras of three points have "polynomiality". Invariant elements which turn out to be cross ratios in the classical limit are defined. For the special case |λ_{ij}| = 1 a quantum cross ratio with properties similar to the classical case is presented. As an application a quantum version of the real Euclidean distance is given.

description: We have observed condensation of fermionic atom pairs in the BCS-BEC crossover regime. A trapped gas of fermionic 40K atoms is evaporatively cooled to quantum degeneracy and then a magnetic-field Feshbach resonance is used to control the atom-atom interactions. The location of this resonance is precisely determined from low-density measurements of molecule dissociation. In order to search for condensation on either side of the resonance we introduce a technique that pairwise projects fermionic atoms onto molecules; this enables us to measure the momentum distribution of fermionic atom pairs. The transition to condensation of fermionic atom pairs is mapped out as a function of the initial atom gas temperature T compared to the Fermi temperature TF for magnetic-field detunings on both the BCS and BEC sides of the resonance.
Corruption in Russia : IKEA's expansion to the East (A-D)
Creators: name: Müller, Urs
Publisher: name: American University
Year: 2023

description: This four-part case series can be used to discuss business ethics, compliance/governance, integrity management, reacting to and preparing against corruption in the context of internationalization and allows to also briefly touching upon the issue of Corporate Social Responsibility (CSR). Case (A) describes a challenge IKEA was facing, while trying to enter Russia in 2000. The company was preparing to open its first flagship store on the outskirts of Moscow, only the first of several planned projects. After substantial investments in infrastructure and logistics, IKEA focused on marketing, but quickly faced a sudden complication. Its major ad campaign in the Moscow Metro with the slogan "[e]very 10th European was made in one of our beds" was labeled "tasteless". IKEA had to stop the campaign because it "couldn't prove" the claim. Soon Lennart Dahlgren, the first general manager of IKEA in Russia must have realized that the unsuccessful ad campaign was going to be the least of his problems: A few weeks before the planned opening, the local utility company decided not to provide their services for the store if IKEA did not pay a bribe. What should IKEA and Lennart Dahlgren do? Was there any alternative to playing the game the Russian way, and paying? The subsequent cases (B), (C), and (D) describe IKEA's creative response to the challenges described in case (A), and then report about new challenges with alleged corruption within IKEA and in the legal environment, and finally raise the question whether IKEA can be considered to have a (corporate social) responsibility to fight corruption on a societal level in order to build the platform for its own operation in Russia. This four-part case series can be used to discuss business ethics, compliance/governance, integrity management, reacting to and preparing against corruption in the context of internationalization and allows to also briefly touching upon the issue of Corporate Social Responsibility (CSR).
Evolution of Massive Black Hole Binaries

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present the result of large-scale N-body simulations of the stellar-dynamical evolution of a massive black-hole binary at the center of a spherical galaxy. We focus on the dependence of the hardening rate on the relaxation timescale of the parent galaxy. A simple theoretical argument predicts that a binary black hole creates the ``loss cone'' around it. Once the loss cone is formed, the hardening rate is determined by the rate at which field stars diffuse into the loss cone. Therefore the hardening timescale becomes proportional to the relaxation timescale. Recent N-body simulations, however, have failed to confirm this theory and various explanations have been proposed. By performing simulations with sufficiently large N (up to $10^6$) for sufficiently long time, we found that the hardening rate does depend on N. Our result is consistent with the simple theoretical prediction that the hardening timescale is proportional to the relaxation timescale. This dependence implies that most massive black hole binaries are unlikely to merge within the Hubble time through interaction with field stars and gravitational wave radiation alone.

description: Cyanide is one of the most potent and rapidly acting inorganic poison and it can cause toxicity in animals, principally in ruminants. “Prussic acid poisoning” is older terminology for cyanide poisoning. Hydrogen cyanide was first isolated from a blue dye (Prussian blue) and because of its acidic nature, it became known by the common name “prussic acid”.

Cyanogenic glycosides present in living plant cells and it can be converted to cyanide by enzymes present in the plant when plant cells are crushed, chewed, wilted and ruptured. Ruminants are very susceptible to cyanide poisoning because the rumen environment is mildly acidic, usually has ample water content, and the microflora can rapidly convert cyanogenic glyocosides in plants to free cyanide gas. s

description: Humid hydrophobic ionic liquids, widely used as electrolytes, have narrowed electrochemical windows, because their water, absorbed on the electrode surface, gets involved in electrolysis. In this work, we performed molecular dynamics simulations to explore effects of adding Li-salt in humid ionic liquids on the water adsorbed on the electrode surface. Results reveal that most of water molecules are pushed away from both cathode and anode, by adding salt. The water remained on the electrode is almost bound with Li+, which has significantly lowered activity. The Li+-bonding and re-arrangement of the surface-adsorbed water both facilitate the inhibition of water electrolysis, and thus prevent the reduction of electrochemical windows of humid hydrophobic ionic liquids. This finding is testified by cyclic voltammetry measurements where salt-in-humid ionic liquids exhibit enhanced electrochemical windows. Our work provides the underlying mechanism and a simple but practical approach for protection of humid ionic liquids from performance degradation.

description: We present the results of electrical resistivity and Hall effect measurements on single crystals of HfNiSn, TiPtSn, and TiNiSn. Semiconducting behavior is observed in each case, involving the transport of a small number of highly compensated carriers. Magnetization measurements suggest that impurities and site disorder create both localized magnetic moments and extended paramagnetic states, with the susceptibility of the latter increasing strongly with reduced temperature. The magnetoresistance is sublinear or linear in fields ranging from 0.01 - 9 Tesla at the lowest temperatures. As the temperature increases, the normal quadratic magnetoresistance is regained, initially at low fields, and at the highest temperatures extending over the complete range of fields. The origin of the vanishingly small field scale implied by these measurements remains unknown, presenting a challenge to existing classical and quantum mechanical theories of magnetoresistance.

description: Light illumination of thin crystals of CDW conductor TaS$_3$ is found to result in dramatic changes of both linear ($G$) and nonlinear conduction. The increase of $G$ is accompanied by suppression of the collective conduction, growth of the threshold field $E_T$, and appearance of the switching and hysteretic behavior in the nonlinear conduction. The effects in the nonlinear conduction are associated with increase of CDW elasticity due to illumination that leads in particular to appearance of a relation $E_T\propto G^{1/3}$ expected for the one-dimensional pinning.

Information Rigidity and Economic Uncertainty: A New Theory and Stylized Facts

Publisher: name: ProQuest
Year: 2023
Subjects: classificationCode: 38
subject: Economics

description: I propose a structural micro-founded sticky-noisy information model with high- and low-uncertainty regimes. Agents first appraise the state of uncertainty and only spend resources to update their inflation expectations if they perceive uncertainty as sufficiently high. Time-varying uncertainty affects expectation formation through two direct channels: 1) the "wake-up call" effect, which causes agents to pay more attention, increasing their quantity of information; and 2) the "wait-and-see" effect, which decreases their quality of information and prompts them to put less weight on new noisier information. Using structural estimation of alternative models with information frictions, I find that accounting for the indirect state-dependence channel, the proposed innovation of the model, better explains the observed information rigidity, since it considers the interaction between the two direct effects. A substantial amount of information rigidity is due to inattention, leaving ample room for policymakers to employ frequent, direct, and simple forward guidance to "pierce the veil" of inattention.

description: Within a cosmological framework, we provide a Hamiltonian analysis of the Mixmaster Universe dynamics on the base of a standard Arnowitt-Deser-Misner approach, showing how the chaotic behavior characterizing the evolution of the system near the cosmological singularity can be obtained as the semiclassical limit of the canonical quantization of the model in the same dynamical representation. The relation between this intrinsic chaotic behavior and the indeterministic quantum dynamics is inferred through the coincidence between the microcanonical probability distribution and the semiclassical quantum one.

The following research aimed to determine the concentrations of five contaminants – fluoranthene, naphthalene, pyrene, decamethylcyclopentasilolxane (D5) and 2,4,6,8-Tetramethylcyclotetrasiloxane (2468) – at five sites within the Anacostia watershed to determine whether there was a correlation between land use patterns and contaminant concentrations. There were no statistically significant differences in contaminant concentrations between urban and suburban sites except for D5, in which urban sites had higher concentrations. There was no statistically significant difference when comparing seasonality to fluoranthene concentrations. There was no predictive relationship at all between population density, precipitation, discharge rates and the concentrations observed. Although 2468 was not identified in any of the samples, these results provided concentrations for fluoranthene, naphthalene, pyrene, and D5 amongst the five chosen sample sites. The average sediment concentrations for fluoranthene (2.70 x 10^1 ± 2.18 x 10^1 µM/g), naphthalene (1.37 x 10^2 ± 1.58 x 10^-2 µM/g), and pyrene (2.01 x 10^2 ± 3.66 x 10^1 µM/g) have increased in comparison to studies published in the early 2000s.

description: Quasinormal mode (QNM) expansion is a popular tool to analyze light-matter interaction in nanoresonators. However, expanding far-field quantities such as the energy flux is an open problem because QNMs diverge with an increasing distance to the resonant systems. We introduce a theory to compute modal expansions of far-field quantities rigorously. The presented approach is based on the complex eigenfrequencies of QNMs. The divergence problem is circumvented by using contour integration with an analytical continuation of the far-field quantity into the complex frequency plane. We demonstrate the approach by computing the angular resolved modal energy flux in the far field of a nanophotonic device.

description: In 1968, using an inheritance from her mother, painter Joan Mitchell (1925-1992) bought a property in Vétheuil, France, where she would live for the rest of her life. There, she created vibrant abstract paintings that combined dripping washes and globular brushwork on white backgrounds, but their titles often referenced foliage, land, and territories. One such work, "White Territory," painted from 1970 to 1971, layered these two types of brushwork through a time-consuming studio practice. Existing scholarship on Mitchell terms her a “Second Generation Abstract Expressionist” and suggests her work pays homage to the formative movement. Rather than read Mitchell’s "White Territory" as belated Abstract Expressionism, my thesis examines the painting’s relationship to the historic home in which it was made. From 1878 to 1881, Monet had owned the Vétheuil property that Mitchell bought almost one hundred years later. There, he painted landscapes of Vétheuil’s cathedral, the river Seine, and his lush garden, capturing the appearance of the countryside and its changing weather patterns. Mitchell’s paintings at Vétheuil evacuated mimetic references to the home and the town and, instead, represented the dynamism of nature itself. Through her slow, calculated process of combining and layering different types of brushwork, in works like "White Territory," Mitchell depicted nature as a force one encounters rather than a site to behold. Her paintings thus reimagined the idea of landscape and re-asserted the significance of nature and painting in the emerging digital age.

description: The four persistent radio sources in the northern sky with the highest flux density at metre wavelengths are Cassiopeia A, Cygnus A, Taurus A, and Virgo A; collectively they are called the A-team. Their flux densities at ultra-low frequencies (<100 MHz) can reach several thousands of janskys, and they often contaminate observations of the low-frequency sky by interfering with image processing. Furthermore, these sources are foreground objects for all-sky observations hampering the study of faint signals, such as the cosmological 21 cm line from the epoch of reionisation. We aim to produce robust models for the surface brightness emission as a function of frequency for the A-team sources at ultra-low frequencies. These models are needed for the calibration and imaging of wide-area surveys of the sky with low-frequency interferometers. This requires obtaining images at an angular resolution better than 15 arcsec with a high dynamic range and good image fidelity. We observed the A-team with the Low Frequency Array (LOFAR) at frequencies between 30 MHz and 77 MHz using the Low Band Antenna (LBA) system. We reduced the datasets and obtained an image for each A-team source. The paper presents the best models to date for the sources Cassiopeia A, Cygnus A, Taurus A, and Virgo A between 30 MHz and 77 MHz. We were able to obtain the aimed resolution and dynamic range in all cases. Owing to its compactness and complexity, observations with the long baselines of the International LOFAR Telescope will be required to improve the source model for Cygnus A further.

description: Motivated by phenomenological models of hidden local symmetries and the ideas of dimensional deconstruction and gauge/gravity duality, we consider the model of an "open moose". Such a model has a large number K of hidden gauge groups as well as a global chiral symmetry. In the continuum limit K->infinity the model becomes a 4+1 dimensional theory of a gauge field propagating in a dilaton background and an external space-time metric with two boundaries. We show that the model reproduces several well known phenomenological and theoretical aspects of low-energy hadron dynamics. We derive the general formulas for the mass spectrum, the decay constants of the pion and vector mesons, and the couplings between mesons. We then consider two simple realizations, one with a flat metric and another with a "cosh" metric interpolating between two AdS boundaries. For the pion form-factor, the single pole rho-meson dominance is exact in the latter case and approximate in the former case. We discover that an AdS/CFT-like prescription emerges in the computation of current-current correlators. We speculate on the role of the model in the theory dual to QCD.

description: Tight-binding molecular dynamics simulations of photo-excitations in small Se clusters (isolated Se$_8$ ring and helical Se chain) and glassy Se networks (containing 162 atoms) were carried out in order to analyse the photo induced instability inside the amorphous selenium. In the cluster systems after taking an electron from the highest occupied molecular orbital to the lowest unoccupied molecular orbital a bond breaking occurs. In the glassy networks photoinduced volume expansion was observed and at the same time the number of coordination defects changed significantly due to illumination.

description: We present a new method for vectorization of technical line drawings, such as floor plans, architectural drawings, and 2D CAD images. Our method includes (1) a deep learning-based cleaning stage to eliminate the background and imperfections in the image and fill in missing parts, (2) a transformer-based network to estimate vector primitives, and (3) optimization procedure to obtain the final primitive configurations. We train the networks on synthetic data, renderings of vector line drawings, and manually vectorized scans of line drawings. Our method quantitatively and qualitatively outperforms a number of existing techniques on a collection of representative technical drawings.

High-precision finite-size scaling analysis of the quantum-critical point of S=1/2 Heisenberg antiferromagnetic bilayers

description: We use quantum Monte Carlo (stochastic series expansion) and finite-size scaling to study the quantum critical points of two S=1/2 Heisenberg antiferromagnets in two dimensions: a bilayer and a Kondo-lattice-like system (incomplete bilayer), each with intra- and inter-plane couplings J and J_perp. We discuss the ground-state finite-size scaling properties of three different quantities--the Binder moment ratio, the spin stiffness, and the long-wavelength magnetic susceptibility--which we use to extract the critical value of the coupling ratio g=J_perp/J. The individual estimates of g_c are consistent provided that subleading finite-size corrections are properly taken into account. In the case of the complete bilayer, the Binder ratio leads to the most precise estimate of the critical coupling, although the subleading finite-size corrections to the stiffness are considerably smaller. For the incomplete bilayer, the subleading corrections to the stiffness are extremely small, and this quantity then gives the best estimate of the critical point. Contrary to predictions, we do not find a universal prefactor of the 1/L spin stiffness scaling at the critical point, whereas the Binder ratio is consistent with a universal value. Our results for the critical coupling ratios are g_c=2.52181(3) (full bilayer) and g_c=1.38882(2) (incomplete bilayer), which represent improvements of two orders of magnitude relative to the previous best estimates. For the correlation length exponent we obtain nu = 0.7106(9), consistent with the expected 3D Heisenberg universality class.

Do quantum states evolve? Apropos of Marchildon's remarks

description: Marchildon's (favorable) assessment (quant-ph/0303170, to appear in Found. Phys.) of the Pondicherry interpretation of quantum mechanics raises several issues, which are addressed. Proceeding from the assumption that quantum mechanics is fundamentally a probability algorithm, this interpretation determines the nature of a world that is irreducibly described by this probability algorithm. Such a world features an objective fuzziness, which implies that its spatiotemporal differentiation does not "go all the way down". This result is inconsistent with the existence of an evolving instantaneous state, quantum or otherwise.

The Relationship Between Helicopter Parenting and the Psychological Well-Being of Emerging Adults
Creators: name: Cole, Caroline I.
Publisher: name: American University
Year: 2023

description: Helicopter parenting refers to the over-involved behavior of parents and/or caregivers who are highly invested and concerned for the well-being of their children. Helicopter parents typically engage in behaviors designed to remove obstacles from their children’s way. Although helicopter parents likely have good intentions for their children, as a child’s need for autonomy progresses, it is important to adjust the level of involvement and control accordingly. The present study represents an initial investigation into the relationship between helicopter parenting behaviors and the well-being of young university students. Participants consisted of 120 college students in their second semester of freshman year and 25 parents of student participants. Students completed measures of helicopter parenting for up to two parents/caregivers (e.g., mother and/or father), parents completed a self-report measure of helicopter parenting, and all participants completed self-report measures of anxiety and depression. Students who reported high levels of helicopter parenting behavior for the parent/caregiver with whom they have the most contact reported significantly higher levels of anxious arousal and lower grade point averages. Female parents/caregivers were reported to exhibit significantly greater helicopter parenting than that of male parents/caregivers. Male students perceived higher levels of helicopter parenting behaviors than female students. Student and parent reports of helicopter parenting were positively correlated with a large correlation coefficient, suggesting concordance between parent and child reports.
