description: We present a tensor formulation for free compact electrodynamics in three Euclidean dimensions and use this formulation to construct a quantum Hamiltonian in the continuous-time limit. Gauge-invariance is maintained at every step and the resulting Hamiltonian can be written as a rotor model. The energy eigenvalues for this Hamiltonian are computed using the tensor formulation, and compared with perturbation theory. We find good agreement between the calculations demonstrating a smooth passage from the statistical lattice Lagrangian description to the quantum Hamiltonian description.

description: We obtain Q-ball solutions in noncommutative scalar field theory with a global U(1) invariance. The Q-ball solutions are shown to be classically and quantum mechanically stable. We also find that "excited Q-ball" states exist for some class of scalar potentials, which are classically stable in the large noncommutativity limit.

description: Nondipole effects in the atomic dynamic interference are investigated by numerically solving the time-dependent Schrödinger equation~(TDSE) of hydrogen. It is found that the inclusion of nondipole corrections in the TDSE can induce momentum shifts of photoelectrons in the opposite direction of the laser propagation. The magnitude of the momentum shift is roughly proportional to the laser peak intensity and to the momentum component of the photoelectron along the laser propagation. By including the nondipole corrections of the Volkov phase into a semi-analytical model previously developed under the dipole approximation, all the main features of the momentum shifts can be nicely reproduced. Through an analytic expression, the origin of such momentum shifts is attributed to the nondipole phase difference between the two electron wave packets ejected in the rising edge and the falling edge, which will interfere with each other and result in the final fringe pattern. One important consequence of such momentum shifts is that they can smooth out the peak splitting induced by the dynamic interference in the photoelectron energy spectrum. Nevertheless, it should be emphasized that the dynamic interference persists in the photoelectron momentum distributions and is not suppressed at all for the laser parameters considered in this work.

description: Coronavirus disease 2019 (COVID-19) has a wide spectrum of disease severity from mild upper respiratory symptoms to respiratory failure. The role of neutralizing antibody (NAb) response in disease progression remains elusive. This study determined the seroprevalence of 733 non-COVID-19 individuals from April 2018 to February 2020 in the Hong Kong Special Administrative Region and compared the neutralizing antibody (NAb) responses of eight COVID-19 patients admitted to the intensive care unit (ICU) with those of 42 patients not admitted to the ICU. We found that NAb against SARS-CoV-2 was not detectable in any of the anonymous serum specimens from the 733 non-COVID-19 individuals. The peak serum geometric mean NAb titer was significantly higher among the eight ICU patients than the 42 non-ICU patients (7280 [95% confidence interval (CI) 1468-36099]) vs (671 [95% CI, 368-1223]). Furthermore, NAb titer increased significantly at earlier infection stages among ICU patients than among non-ICU patients. The median number of days to reach the peak Nab titers after symptoms onset was shorter among the ICU patients (17.6) than that of the non-ICU patients (20.1). Multivariate analysis showed that oxygen requirement and fever during admission were the only clinical factors independently associated with higher NAb titers. Our data suggested that SARS-CoV-2 was unlikely to have silently spread before the COVID-19 emergence in Hong Kong. ICU patients had an accelerated and augmented NAb response compared to non-ICU patients, which was associated with disease severity. Further studies are required to understand the relationship between high NAb response and disease severity.
On the quantum dynamics of Davydov solitons in protein $α$-helices

description: The transport of energy inside protein $α$-helices is studied by deriving a system of quantum equations of motion from the Davydov Hamiltonian with the use of the Schrödinger equation and the generalized Ehrenfest theorem. Numerically solving the system of quantum equations of motion for different initial distributions of the amide I energy over the peptide groups confirmed the generation of both moving or stationary Davydov solitons. In this simulation the soliton generation, propagation, and stability were found to be dependent on the symmetry of the exciton-phonon interaction Hamiltonian and the initial site of application of the exciton energy.

Η μέθοδος που αναπτύξαμε ονομάζεται Spatial Pyramid with Vectors of Locally Aggregated Descriptors (SP-VLAD) και σχεδιάστηκε με γνώμονα την εφαρμογή της στο πρόβλημα της ανάκτησης εικόνων με τρόπο που να επιτυγχάνεται υψηλή ακρίβεια και αποδοτικότητα, με χαμηλές απαιτήσεις μνήμης. Η μέθοδος SP-VLAD στηρίζεται στις ιδέες των μεθόδων Spatial Pyramid Matching (SPM) και Vector of Locally Aggregated Descriptors (VLAD). Συγκεκριμένα, συνδυάζει τη δομή της χωρικής πυραμίδας με τα διανύσματα VLAD. Η αξιολόγηση της μεθόδου SP-VLAD οδήγησε σε αισθητά υψηλότερες επιδόσεις σε σχέση με τις μεθόδους SPM και VLAD. Γι' αυτό το λόγο εφαρμόστηκε και στο πρόβλημα της κατηγοριοποίησης εικόνων, όπου ξεπέρασε το βαθμό κατηγορίοποιησης των μεθόδων SPM και VLAD στις βάσεις εικόνων στις οποίες δοκιμάστηκε. Οι εξαιρετικές επιδόσεις της μεθόδου SP-VLAD επετεύχθησαν με πολύ χαμηλές απαιτήσεις μνήμης μετά την μείωση της διάστασης των τελικών διανυσμάτων περιγραφής στις 128 και 64 διαστάσεις μέσω της μεθόδου PCA. Στο πλαίσιο της ερευνητικής μας δραστηριότητας δημιουργήθηκε η νέα βάση εικόνων Flowers 15 με σκοπό την εφαρμογή της μεθόδου SP-VLAD σε εικόνες ανθοφόρων φυτών.
description: We propose a new method for the vector representation of an image which is based on aggregation of image descriptors while exploiting their spatial information. Our method, Spatial Pyramid with Vectors of Locally Aggregated Descriptors (SP-VLAD), was designed for the problem of image retrieval in order to achieve high accuracy and efficiency, with low memory requirements. SP-VLAD is based on the ideas of two other methods, Spatial Pyramid Matching (SPM) and Vector of Locally Aggregated Descriptors (VLAD). Specifically, it combines the idea of spatial pyramid with the VLAD descriptor vectors. The SP-VLAD method achieves high accuracy and significantly outperforms SPM and VLAD methods. Τhe promising results led us to apply our method to the problem of image classification as well; exceeding the classification rate of SPM and VLAD methods on all databases which were used. The excellent results of our method were achieved with low memory usage after the dimension reduction of the descriptor vectors with the PCA method which resulted to vectors of 64 or 128 dimensions. We also created the dataset Flowers 15 for the needs of our research in order to be able to test the SP-VLAD method upon images of flowering plants.

description: The $U(1)\times SU(2)$ Chern-Simons gauge theory is applied to study the 2-D $t-J$ model describing the normal state of underdoped cuprate superconductors. The U(1) field produces a flux phase for holons converting them into Dirac-like fermions, while the SU(2) field, due to the coupling to holons gives rise to a gap for spinons. An effective low-energy action involving holons, spinons and a self-generated U(1) gauge field is derived. The Fermi surface and electron spectral function obtained are consistent with photoemission experiments. The theory predicts a minimal gap proportional to doping concentration. It also explains anomalous transport properties including linear $T$ dependence of the in-plane resistivity.

description: Injectable and/or Implantable medical devices are widely used in the treatment of diseases. Among them, vascular stents provide the medical solution to treat blood clotting. However, traditional metallic stents, even with current improvements in anticoagulation properties, have potential drawbacks in local inflammation when first implanted into the body and undesirable protein adsorption and cell adhesion after a prolonged period of time in the body. In this perspective, we discuss several engineering approaches, including drug-eluting materials, polymeric and non-polymeric coatings, and surface modifications to coating materials that can be applied to the surface of medical implants to significantly improve the hemocompatibility. These coatings are expected to have a slow degradation rate with the ability to either load drugs or attach biomacromolecules to form an architecture that mimics the surrounding cells. In general, our perspective provides a current view on the achievements of hemo-compatible coatings and future trends in coating materials that will extend the life of the medical implants.

description: Previous studies of the structure of liquid water under pressure performed by neutron diffraction, allowed us to establish two structural limits in liquid water. These two limits are closely connected to the two known forms of amorphous ice : the low density amorphous ice (LDA) and the high density amorphous ice (HDA). In the present paper, we propose some interpretation of our data in terms of a two level type model of water. This leads to show some evidence of a liquid-liquid phase transition in liquid supercooled water. The result looks in agreement with recent computer simulations that incorporate the two forms of amorphous ice.

description: We propose Multi-Strategy Coevolving Aging Particles (MS-CAP), a novel population-based algorithm for black-box optimization. In a memetic fashion, MS-CAP combines two components with complementary algorithm logics. In the first stage, each particle is perturbed independently along each dimension with a progressively shrinking (decaying) radius, and attracted towards the current best solution with an increasing force. In the second phase, the particles are mutated and recombined according to a multi-strategy approach in the fashion of the ensemble of mutation strategies in Differential Evolution. The proposed algorithm is tested, at different dimensionalities, on two complete black-box optimization benchmarks proposed at the Congress on Evolutionary Computation 2010 and 2013. To demonstrate the applicability of the approach, we also test MS-CAP to train a Feedforward Neural Network modelling the kinematics of an 8-link robot manipulator. The numerical results show that MS-CAP, for the setting considered in this study, tends to outperform the state-of-the-art optimization algorithms on a large set of problems, thus resulting in a robust and versatile optimizer.
Properties of general relativistic, irrotational binary neutron stars in close quasiequilibrium orbits : Polytropic equations of state

description: We investigate close binary neutron stars in quasiequilibrium states in a general relativistic framework. We assume conformal flatness for the spatial metric and irrotational velocity field for the neutron stars. We adopt the polytropic equation of state. The computation is performed for the polytropic index n(=0.5, 0.66667, 0.8, 1, 1.25), and compactness of neutron stars M/R(=0.03 - 0.3). Results of this paper are as follows. (i) The sequences of the irrotational binary are always terminated at an innermost orbit where a cusp (inner Lagrange point)appears at the inner edges of the stellar surface. The binaries with cusps are found to be dynamically unstable for n=0.5 and stable for n > 0.8 irrespective of M/R < 0.2. For n=0.66667, the stability changes depending on M/R. (ii) The gravitational wave frequency at the innermost orbit turns out to be between 800 and 1500 Hz for realistic compactness 0.14 < M/R < 0.2. (iii) The ISCO for n=0.5 appears to be determined by a hydrodynamic instability for M/R < 0.2. We derive fitting formulae for the relation between the orbital angular velocity at the ISCO and the compactness to clarify it. (iv) The maximum density of neutron stars in binary systems slightly decreases with decreasing the orbital separation and hence they are stable against individual radial collapse during the inspiral. (v) q = J_tot/M_ADM^2 at the innermost orbits is always less than unity for M/R > 0.13 irrespective of n, which indicates that the realistic binary neutron stars satisfy a necessary condition (q<1) for formation of a black hole before the merger. (vi) The specific angular momentum of any mass element in irrotational binary neutron stars at the innermost orbit appears to be too small to form a disk around black holes formed after the merger.

description: Two-dimensional (2D) semiconductors exhibit great potential to minimize the size and drastically reduce the energy consumption of optoelectronic devices due to promising features induced by quantum confinement. It has achieved many successes in infrared and visible light optoelectronic devices. The study on ultra-wide band gap 2D semiconductors except h-BN are still limited, however, the requirement is more and more urgent. Inspired by the progresses of III-nitride semiconductors in recent several decades, 2D AlN is highly expected to be a new member of ultra-wide band gap 2D semiconductors. In this work, we employed the first-principles calculations to investigate the structural and electronic properties of 2D AlN. We revealed that few-layer AlN acquires a square-octagon (so-AlN) configuration in the vertical direction when the number of atomic layers n is smaller than 16. With increasing the thickness from 2 ML to 8 ML, the band gap decreased due to the weakening of quantum confinement effect. We demonstrated the intrinsic indirect band gap can be tuned to be direct by applying different direction strains for so-AlN. Our results open new avenues for their application in nano-optoelectronics.

description: In this work we explore accurate new ways to derive the ionization parameter ($U$) and the equivalent effective temperature ($T_*$) in HII regions using emission-line intensities from the ionized gas. The so-called softness parameter ($η$), based on [OII], [OIII], [SII], and [SIII] has been proposed to estimate the hardening of the ionizing incident field of radiation, but the simplest relation of this parameter with $T_*$ also depends on $U$ and metallicity ($Z$). Here we provide a Bayesian-like code (HCm-Teff) that compares the observed emission lines of $η$ with the predictions of a large grid of photoionization models giving precise estimations of both $U$ and $T_*$ when $Z$ is known. We also study the radial variation of these parameters in well-studied disc galaxies observed by the CHAOS collaboration. Our results indicate that the observed radial decreasing of $η$ can be attributed to a radial hardening of $T_*$, across galactic discs as in NGC~628 and NGC~5457. On the other hand NGC~5194, which presents a positive slope of the fitting of the softness parameter, has a flat slope in $T_*$. On the contrary the three galaxies do not seem to present large radial variations of the ionization parameter. When we inspect a larger sample of galaxies we observe steeper radial variations of $T_*$ in less bright and later-type galaxies, mimicking a similar trend observed for $Z$ but the studied sample should be enlarged to obtain more statistically significant conclusions.

Fraud By the National Australia Bank and The Theft of customer funds
Creators: name: Buckman, Paul
Publisher: name: Federation University Australia

Subjects: Uncategorized

description: The matters discussed here had their genesis during 1998 and 1999 and relate to instances of theft and fraud engaged in by the National Australia Bank against their customer (Basstech Pty Ltd, acn 006035301 (deregistered 2004)). A long consistent history of matters such as this example saw the establishment of The Royal Commission into the Banking and Financial Services sector (2018). These, the Basstech matters, remain unresolved to this day.
Any resolution of crimes such as these must be enacted through the criminal prosecution of the “Corporation”; that is the corporation as a “corporate citizen, a person before the law”.

This paper examines one case of theft and fraud by a bank, the problems endemic in corporate prosecution, the personality of the corporation and then explores methods of control and prosecution.

description: The correlation length of the square-lattice spin-1/2 Heisenberg antiferromagnet is studied in the low-temperature (asymptotic-scaling) regime. Our novel approach combines a very efficient loop cluster algorithm -- operating directly in the Euclidean time continuum -- with finite-size scaling. This enables us to probe correlation lengths up to $ξ\approx 350,000$ lattice spacings -- more than three orders of magnitude larger than any previous study. We resolve a conundrum concerning the applicability of asymptotic-scaling formulae to experimentally- and numerically-determined correlation lengths, and arrive at a very precise determination of the low-energy observables. Our results have direct implications for the zero-temperature behavior of spin-1/2 ladders.

Numerical study of vortex matter using the Bose model: First-order melting and entanglement

description: We present an extensive numerical study of vortex matter using the mapping to 2D bosons and Path-Integral Monte Carlo simulations. We find a first-order vortex lattice melting transition into an entangled vortex liquid. The jumps in entropy and density are consistent with experimental results on YBCO. The liquid is denser than the lattice and has a correlation length l_z approx 1.7 epsilon a_0 in the direction parallel to the field. In the language of bosons we find a sharp quantum phase transition from a Wigner crystal to a superfluid, even in the case of logarithmic interaction. We also measure the excitation spectrum of the Bose system and find the roton minimum to be insensitive to the range of the interaction.

An improved formulation of Jaccard's theory of the electric properties of ice

Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: In the standard derivation of Jaccard's theory of the electric properties of ice, no fundamental distinction is made between bound and free charges. This leads to some didactical problems like the ad hoc introduction of the so-called 'configuration vector' $\bfΩ$. However, when the two types of charges are distinguished, it becomes clear that $\bfΩ$ is redundant and proportional to the polarisation density. We also show that Jaccard's formulation contains a wrong formula for the electric susceptibility and that the correct $Φ$ factor can be derived from a straightforward kinetic approach (which Jaccard failed to do).

description: We introduce and study an exactly solvable model of several species of fermions in which particles interact pairwise through a mutual magnetic field; the interaction operates only between particles belonging to different species. After an unitary transformation, the model reduces to one in which each particle sees a magnetic field which depends on the total numbers of particles of all the other species; this may be viewed as the mean-field model for a class of anyonic theories. Our model is invariant under charge conjugation C and the product PT (parity and time reversal). For the special case of two species, we examine various properties of this system, such as the Hall conductivity, the wave function overlap arising from the transfer of one particle from one species to another, and the one-particle off-diagonal density matrix. Our model is a generalization of a recently introduced solvable model in one dimension.

description: Very recently we developed an efficient method to calculate the free energy of 2D materials on substrates and achieved high calculation precision for graphene or $γ$-graphyne on copper substrates. In the present work, the method was further confirmed to be accurate by molecular dynamic simulations of silicene on Ag substrate using empirical potential and was applied to predict the optimum conditions based on \emph{ab initio} calculations for silicene growth on Ag (110) and Ag (111) surface, which are in good agreement with previous experimental observations.

description: We calculate the specific heat of the antiferromagnetic spin-1 chain compound Y_2BaNi_{1-x}Zn_xO_5 in the presence of a magnetic field. The low-energy spectrum of a Heisenberg Hamiltonian, which includes realistic anisotropies, has been solved using the density matrix renormalization group. The observed Schottky anomaly is very well described by this theory. For large chains ($N>50$), contrary to previous interpretations of the specific heat data, we find S=1/2 states. These results are thus also consistent with electron- spin-resonance data for NENP.

description: We study the reflection amplitudes of affine Toda field theories with boundary, following the ideas developed by Fring and Koberle and focusing our attention on the $E_{n}$ series elements, because of their interesting structure of higher order poles. We also investigate the corresponding minimal reflection matrices, finding, with respect to the bulk case, a more complicated relation between the spectra of bound states associated to the minimal and to the ''dressed'' amplitudes.

title: Effect of Sampling Errors on Estimates of Recruitment and Fishing Mortality from Separable Virtual Population Analysis

publisherIdentifier: https://ror.org/04zjtrb98

description: Separable virtual population analysis (SVPA) models provide estimates of historical recruitment and fishing mortality from analyzing catch data based on the separability of fishing mortality into age specific-gear selection and yearly mortality. These models assume that the catch is randomly sampled and that sampling error is a random variable with constant variance and mean equal to zero. These models do not account for sampling measurement errors that occur when the catch partitioned by age is not measured on every sampling unit without error, and spatio-temporal errors that occur when the observed catch is not representative of the harvested population throughout time and space. I studied the effect of these sampling errors on estimates of recruitment and fishing mortality from the SVPA of Pope and Shepherd (1982) based on the catch (1986- 1996) in the Atlantic menhaden fishery. Underreporting total catch by 20% underestimated recruitment in the same magnitude, but did not result in observable error in fishing mortality. When undercoverage of spatial areas was modeled by a deterministic simulation, average errors in recruitment and fishing mortality were estimated to be from 6% to 116% over the simulated period. Using bootstrapping, I found that stochastic-sampling errors in mean weight also biased estimates of recruitment and fishing mortality, on average up to 8% for the simulated period. In the presence of measurement errors, SVPA underestimated recruitment, but correctly estimated fishing mortality, whereas in the presence of sampling spatial errors SVPA failed to correctly estimate both recruitment and fishing mortality. Thus, sampling errors are potential sources of substantial errors beyond those associated with ageing fish, estimating proportion of fish by age, and improper parametization of a model.

description: In the context of non-critical Liouville strings, we clarify why we expect non-quantum-mechanical dissipative effects to be of order E^2/M_P, where E is a typical energy scale of the probe, and M_P is the Planck scale. In Liouville strings, energy is conserved {\it at best} only as a statistical average, as distinct from Lindblad systems, where it is {\it strictly} conserved at an operator level, and the magnitude of dissipative effects could only be much smaller. We also emphasize the importance of nonlinear terms in the evolution equation for the density matrix, which are important for any analysis of complete positivity.

description: We present CO(J= 1-0; 3-2; 5-4; 10-9) and 1.2-kpc resolution [CII] line observations of the dusty star-forming galaxy (SFG) HXMM05 -- carried out with the Karl G. Jansky Very Large Array, the Combined Array for Research in Millimeter-wave Astronomy, the Plateau de Bure Interferometer, and the Atacama Large Millimeter/submillimeter Array, measuring an unambiguous redshift of z = 2.9850+/-0.0009. We find that HXMM05 is a hyper-luminous infrared galaxy (LIR=(4+/-1)x10^13 Lsun) with a total molecular gas mass of (2.1+/-0.7)x10^11 (alpha_CO/0.8) Msun. The CO(J=1-0) and [CII] emission are extended over ~9 kpc in diameter, and the CO line FWHM exceeds 1100 km s^-1. The [CII] emission shows a monotonic velocity gradient consistent with a disk, with a maximum rotation velocity of v_c = 616+/-100 km s^-1 and a dynamical mass of (7.7+/-3.1)x10^11 Msun. We find a star formation rate (SFR) of 2900^750_-595 Msun yr^-1. HXMM05 is thus among the most intensely star-forming galaxies known at high redshift. Photo-dissociation region modeling suggests physical conditions similar to nearby SFGs, showing extended star formation, which is consistent with our finding that the gas and dust emission are co-spatial. Its molecular gas excitation resembles the local major merger Arp 220. The broad CO and [CII] lines and a pair of compact dust nuclei suggest the presence of a late-stage major merger at the center of the extended disk, again reminiscent of Arp 220. The observed gas kinematics and conditions together with the presence of a companion and the pair of nuclei suggest that HXMM05 is experiencing multiple mergers as a part of the evolution.

Centered rarefaction wave with a liquid-gas phase transition in the approximation of "phase-flip" hydrodynamics
Creators: name: Basko, Mikhail M.
Publisher: name: arXiv
Year: 2018

description: It is proposed to evaluate the effects of thermodynamic metastability on fluid dynamics by comparing two different ideal-hydrodynamics solutions --- one obtained with the fully equilibrium equation of state using the Maxwell construction, and the other in what we call the phase-flip approximation. The latter is based on the assumption of instantaneous decay of metastable states upon reaching the spinodal. The proposed method is applied to the classical problem of the centered rarefaction wave by expansion into vacuum, for which exact analytical solutions exist in both approximations. It is shown that the rapid decay of metastable states leads to the formation of a rarefaction shock in the expanding flow. Implications for the laser-heating experiments are discussed.
