description: The notion of optical geometry, introduced more than twenty years ago as a formal tool in quantum field theory on a static background, has recently found several applications to the study of physical processes around compact objects. In this paper we define optical geometry for spherically symmetric gravitational collapse, with the purpose of extending the current formalism to physically interesting spacetimes which are not conformally static. The treatment is fully general but, as an example, we also discuss the special case of the Oppenheimer-Snyder model. The analysis of the late time behaviour shows a close correspondence between the structure of optical spacetime for gravitational collapse and that of flat spacetime with an accelerating boundary. Thus, optical geometry provides a natural physical interpretation for derivations of the Hawking effect based on the ``moving mirror analogy.'' Finally, we briefly discuss the issue of back-reaction in black hole evaporation and the information paradox from the perspective of optical geometry.

description: In this paper we study Dixmier traces of powers of Hankel operators in Lorentz ideals. We extend results of Engliš-Zhang to the case of powers $p\geq 1$ and general Lorentz ideals starting from abstract extrapolation results of Gayral-Sukochev. In the special case $p=2,4,6$ we give an exact formula for the Dixmier trace. For general $p$, we give upper and lower bounds on the Dixmier trace. We also construct, for any $p$ and any Lorentz ideal, examples of non-measurable Hankel operators.

Elasticity, Shape Fluctuations and Phase Transitions in the New Tubule Phase of Anisotropic Tethered Membranes

description: We study the shape, elasticity and fluctuations of the recently predicted (cond-mat/9510172) and subsequently observed (in numerical simulations) (cond-mat/9705059) tubule phase of anisotropic membranes, as well as the phase transitions into and out of it. This novel phase lies between the previously predicted flat and crumpled phases, both in temperature and in its physical properties: it is crumpled in one direction, and extended in the other. Its shape and elastic properties are characterized by a radius of gyration exponent $ν$ and an anisotropy exponent $z$. We derive scaling laws for the radius of gyration $R_G(L_\perp,L_y)$ (i.e. the average thickness) of the tubule about a spontaneously selected straight axis and for the tubule undulations $h_{rms}(L_\perp,L_y)$ transverse to its average extension. For phantom (i.e. non-self-avoiding) membranes, we predict $ν=1/4$, $z=1/2$ and $η_κ=0$, exactly, in excellent agreement with simulations. For membranes embedded in the space of dimension $d<11$, self-avoidance greatly swells the tubule and suppresses its wild transverse undulations, changing its shape exponents $ν$ and $z$. We give detailed scaling results for the shape of the tubule of an arbitrary aspect ratio and compute a variety of correlation functions, as well as the anomalous elasticity of the tubules. Finally we present a scaling theory for the shape of the membrane and its specific heat near the continuous transitions into and out of the tubule phase and perform detailed renormalization group calculations for the crumpled-to-tubule transition for phantom membranes.

description: We investigate the status of models containing exotic fermions or extra Z-like neutral gauge bosons in the light of the recent data on anomalous magnetic moment of muon. We find that it is possible to extract interesting bounds on the parameters characterizing such models. The bounds are particularly strong if the new flavour-changing neutral currents are axial vectorlike.

description: We consider the herding to non-herding transition caused by idiosyncratic choices or imperfect imitation in the context of the Kirman Model for financial markets, or equivalently the Noisy Voter Model for opinion formation. In these original models this is a finite size transition that disappears for a large number of agents. We show how the introduction of two different mechanisms make this transition robust and well defined. A first mechanism is nonlinear interactions among agents taking into account the nonlinear effect of local majorities. The second one is aging, so that the longer an agent has been in a given state the more reluctant she becomes to change state.

Το SOM αρχικά χρησιμοποιείται ως τελεστής αναπαραγωγής όπου τα πρότυπα εκπαίδευσης αναλαμβάνουν το ρόλο των γονέων και το εκπαιδευμένο δίκτυο SOM συνθέτει την επόμενη γενιά. Στη συνέχεια το SOM χρησιμοποιείται ως μεταπρότυπο αξιολόγησης, βασισμένο σε ένα αριθμό προηγούμενων αξιολογήσεων και για το προς αξιολόγηση διάνυσμα σχεδιασμού επιστρέφει μια προσεγγιστική τιμή της αντικειμενικής του συνάρτησης. Ως τρίτη και τελευταία χρήση, το SOM συνδυάζεται με μια μέθοδο ομαδοποίησης και χρησιμοποιείται για να διευκολυνθεί η παρουσίαση και η κατανόηση αποτελεσμάτων πολυκριτηριακής βελτιστοποίησης. Και οι τρείς μέθοδοι εφαρμόζονται τόσο σε προβλήματα ελαχιστοποίησης μαθηματικών συναρτήσεων όσο και σε προβλήματα βελτιστοποίησης στην αεροδυναμικής.
description: The present Diploma Thesis on different ways of using a particular class of neural networks, i.e. the so called Self-Organizing Maps (SOMs), to support the efficient use of Evolutionary Algorithms in aerodynamic optimization. In the first method, SOMs are used as reproduction operator where the training patterns correspond to the parent population and the trained SOM nodes correspond the new generation members (offspring). In the second method, SOMs are used as evaluation metamodel, that returns an approximate fitness function value. The last SOM’s usage serves to increase the comprehension of the optimization results. All three methods are used in function minimization and aerodynamic optimization problems.

A Viscoelastic model of phase separation

description: We show here a general model of phase separation in isotropic condensed matter, namely, a viscoelastic model. We propose that the bulk mechanical relaxation modulus that has so far been ignored in previous theories plays an important role in viscoelastic phase separation in addition to the shear relaxation modulus. In polymer solutions, for example, attractive interactions between polymers under a poor-solvent condition likely cause the transient gellike behavior, which makes both bulk and shear modes active. Although such attractive interactions between molecules of the same component exist universally in the two-phase region of a mixture, the stress arising from attractive interactions is asymmetrically divided between the components only in dynamically asymmetric mixtures such as polymer solutions and colloidal suspensions. Thus, the interaction network between the slower components, which can store the elastic energy against its deformation through bulk and shear moduli, is formed. It is the bulk relaxation modulus associated with this interaction network that is primarily responsible for the appearance of the sponge structure peculiar to viscoelastic phase separation and the phase inversion. We demonstrate that a viscoelastic model of phase separation including this new effect is a general model that can describe all types of isotropic phase separation including solid and fluid models as its special cases without any exception, if there is no coupling with additional order parameter. The physical origin of volume shrinking behavior during viscoelastic phase separation and the universality of the resulting spongelike structure are also discussed.

Results of seismic and infrasound noise, electromagnetic attenuation and cosmic muon radiation measurements are reported in the underground Matra Gravitational and Geophysical Laboratory near Gyöngyösoroszi, Hungary. The collected seismic data of more than two years is evaluated from the point of view of the Einstein Telescope, a proposed third generation underground gravitational wave observatory. Applying our results for the site selection will significantly improve the signal to nose ratio of the multi-messenger astrophysics era, especially at the low frequency regime.

description: Here, we describe a method for the enhanced self-assembly of triblock Janus colloids targeted to form a kagome lattice. Using computer simulations, we demonstrate that the formation of this elusive structure can be significantly improved by self-propelling or activating the colloids along the axis connecting their hydrophobic hemispheres. The process by which metastable aggregates are destabilized and transformed into the favored kagome lattice is quite general, and we argue this active approach provides a systematic pathway to improving the self-assembly of a large number of colloidal structures.

description: Current drought and water scarcity management in England and Wales is reactive rather than proactive and the array of instruments and measures focuses primarily on what to do when in a drought, but less on how to prevent a drought or to plan ahead for a drought. This paper presents the results of a workshop that was held in late 2016 with stakeholders and researchers from UK drought and water scarcity management – the environment ministry (Department for Environment, Food and Rural Affairs), the Environment Agency, water companies, the economic regulator and water consultancies using the explorative scenario technique. The workshop offered the opportunity for unconstrained blue-sky thinking about drought management options based on the question What can happen? and it is useful in cases where there is fairly good knowledge regarding how the system works at present, but one is interested in exploring the consequences of alternative developments in drought management. The workshop developed four scenarios on the topic of resilient drought and water scarcity management in England and Wales in 2065: (1) ‘Accepting decline’, (2) ‘Rising to the challenge’, (3) ‘Enjoying their luck’ and (4) ‘Passive acceptance’. The corresponding narratives are presented as are limits of the workshop but also potential uses of the scenarios.

description:
Much of what is known and theorized concerning passive sampling techniques has been developed considering chemical analytes. Yet, historically, biological analytes, such as Salmonella typhi, have been collected from wastewater via passive sampling with Moore swabs. In response to the COVID-19 pandemic, passive sampling is re-emerging as a promising technique to monitor SARS-CoV-2 RNA in wastewater. Method comparisons and disease surveillance using composite, grab, and passive sampling for SARS-CoV-2 RNA detection have found passive sampling with a variety of materials routinely produced qualitative results superior to grab samples and useful for sub-sewershed surveillance of COVID-19. Among individual studies, SARS-CoV-2 RNA concentrations derived from passive samplers demonstrated heterogeneous correlation with concentrations from paired composite samples ranging from weak (R2 = 0.27, 0.31) to moderate (R2 = 0.59) to strong (R2 = 0.76). Among passive sampler materials, electronegative membranes have shown great promise with linear uptake of SARS-CoV-2 RNA observed for exposure durations of 24 to 48 h and in several cases RNA positivity on par with composite samples. Continuing development of passive sampling methods for the surveillance of infectious diseases via diverse forms of fecal waste should focus on optimizing sampler materials for the efficient uptake and recovery of biological analytes, kit-free extraction, and resource-efficient testing methods capable of rapidly producing qualitative or quantitative data. With such refinements passive sampling could prove to be a fundamental tool for scaling wastewater surveillance of infectious disease, especially among the 1.8 billion persons living in low-resource settings served by non-traditional wastewater collection infrastructure.

description: We examine the spectra of 23 fast radio bursts detected in a fly's-eye survey with the Australian SKA Pathfinder, including those of three bursts not previously reported. The mean spectral index of $α= -1.6_{-0.2}^{+0.3}$ ($F_ν\propto ν^α$) is close to that of the Galactic pulsar population. The sample is dominated by bursts exhibiting a large degree of spectral modulation: 17 exhibit fine-scale spectral modulation with an rms exceeding 50% of the mean, with decorrelation bandwidths (half-maximum) ranging from $\approx$ to 49 MHz. Most decorrelation bandwidths are an order of magnitude lower than the $\gtrsim 30\,$MHz expected of Galactic interstellar scintillation at the Galactic latitude of the survey, $|b| = 50 \pm 5 °$. A test of the amplitude distribution of the spectral fluctuations reveals only 12 bursts consistent at better than a 5% confidence level with the prediction of 100%-modulated diffractive scintillation. Moreover, five of six FRBs with a signal-to-noise ratio exceeding 18 are consistent with this prediction at less than 1% confidence. Nonetheless, there is weak evidence (88-95% confidence) that the amplitude of the fine-scale spectral modulation is anti-correlated with dispersion measure (DM) that would suggest it originates as a propagation effect. This effect appears to be corroborated by the smoothness of the higher-DM Parkes FRBs, and could arise due to quenching of diffractive scintillation (e.g. in the interstellar medium of the host galaxy) by angular broadening in the intergalactic medium.

description: Recent astrophysical observations seem to indicate that the cosmological constant is small but nonzero and positive. The old cosmological constant problem asks why it is so small; we must now ask, in addition, why it is nonzero (and is in the range found by recent observations), and why it is positive. In this essay, we try to kill these three metaphorical birds with one stone. That stone is the unimodular theory of gravity, which is the ordinary theory of gravity, except for the way the cosmological constant arises in the theory. We argue that the cosmological constant becomes dynamical, and eventually, in terms of the cosmic scale factor $R(t)$, it takes the form $Λ(t) = Λ(t_0)(R(t_0)/R(t))^2$, but not before the epoch corresponding to the redshift parameter $z \sim 1$.
description: A discussion on the form of the cosmological constant (inversely proportional to the square of the cosmic scale factor) after the epoch corresponding to the redshift $z \sim 1$ is added. Two new references are added. This version of the paper will appear in Int. J. Mod. Phys. D

description: Renal cell carcinoma (RCC) is a common malignant tumour affecting the urinary system, and multidrug resistance is one of the major reasons why chemotherapy for this type of cancer often fails. Previous studies have shown that loss of the human organic cation transporter OCT2 is the main factor contributing to oxaliplatin resistance in RCC, and that DNA hypermethylation and histone methylation play important roles in the transcriptional repression of OCT2 in RCC. In this study, we found that histone acetylation also regulates OCT2 repression in RCC and elucidated the underlying mechanisms. In normal renal cells, HDAC7 combines with MYC at the OCT2 promoter, resulting in a decrease in free HDAC7, which in turn increases the levels of H3K18ac and H3K27ac at the OCT2 promotor and activates OCT2 expression. In RCC cells, however, the interaction between HDAC7 and MYC does not occur, which leads a high abundance of HDAC7 and low levels of H3K18ac and H3K27ac at the OCT2 promoter, thereby resulting in the inhibition of OCT2 transcription. We found that combined treatment using the DNA methylation inhibitor decitabine and the histone deacetylase inhibitor vorinostat significantly increased the expression of OCT2 in RCC cell lines, which sensitized these cells to oxaliplatin. We accordingly propose that the combination of anticancer agents and epigenetic drugs can provide a novel chemotherapeutic regimen.

description: We propose here a new mechanism of droplet coarsening in phase-separating fluid mixtures. In contrast to the conventional understanding that there are no interactions between droplets in the late stage of spinodal decomposition, we demonstrate the existence of interactions between droplets that is caused by the coupling between diffuse concentration change around droplets. We show the possibility that this mechanism plays an important role in droplet phase separation together with Brownian-coagulation mechanism. We also discuss the coupling between hydrodynamic and diffusion modes, namely, "collision-induced collision" phenomena.

description: In ionic materials, circularly polarized phonons carry orbital magnetic moments that arise from circular motions of the ions, and which interact with other magnetic moments or fields. Here, we calculate the orbital magnetic moments of phonons in 35 different materials using density functional theory, and we identify the factors that lead to, and materials that show, large responses. We compute the resulting macroscopic orbital magnetic moments that can be induced by the excitation of coherent phonons using mid-infrared laser pulses, and we evaluate the magnitudes of the phonon Zeeman effect in a strong magnetic field. Finally, we apply our formalism to chiral phonons, in which the motions of the ions are intrinsically circular. The zoology presented here may serve as a guide to finding materials for phonon and spin-phonon driven phenomena.

description: The non-commutative version of the euclidean $g^2ϕ^4$ theory is considered. By using Wilsonian flow equations the ultraviolet renormalizability can be proved to all orders in perturbation theory. On the other hand, the infrared sector cannot be treated perturbatively and requires a resummation of the leading divergencies in the two-point function. This is analogous to what is done in the Hard Thermal Loops resummation of finite temperature field theory. Next-to-leading order corrections to the self-energy are computed, resulting in $O(g^3)$ contributions in the massless case, and $O(g^6\log g^2)$ in the massive one.
description: 4 pages, 3 figures. The resummation procedure is now discussed also at finite ultraviolet cut-off. Minor changes in abstract and references. Final version to be published in Physical Review Letters

description: We analyze the known results for the eigenvalue of the Balitsky-Fadin-Kuraev-Lipatov (BFKL) equation in the perturbative regime using the analytic continuation of harmonic sums from even positive arguments to the complex plane. The resulting meromorphic functions have poles at negative integer values of the argument. The typical classification of harmonic sums is determined by two major parameters: $a)$ the \textit{weight} - a sum of inverse powers of the summation indices; $b)$ the \textit{depth} - a number of nested summations. We introduce the third parameter: the \textit{alternation} - a number of nested sign-alternating summations in a given harmonic sum. We claim that the maximal alternation of the nested summation in the functions building the BFKL eigenvalue is preserved from loop to loop in the perturbative expansion. The BFKL equation is formulated for arbitrary color configuration of the propagating states in the $t$-channel. Based on known results one can state that color adjoint BFKL eigenvalue be can written using only harmonic sums with positive indices, maximal alternation zero, and at most depth one, whereas the singlet BFKL eigenvalue is constructed of harmonic sums with maximal sign alternation being equal one. We also note that for maximal alternation being equal unity the harmonic sums can be expressed through alternation zero harmonic sums with half-shifted arguments.

description: Recombinant human HER2 monoclonal antibody for injection (AK-HER2) is a potential biosimilar of trastuzumab (Herceptin®). This phase Ⅰ study aimed to demonstrate the pharmacokinetic (PK) equivalence between AK-HER2 and trastuzumab in healthy volunteers. Besides, safety and immunogenicity were investigated. This was a randomized, double-blind phase Ⅰ trial in 96 healthy adults who received a single intravenous infusion of AK-HER2 or trastuzumab at 6 mg/kg. The primary PK endpoints were area under the serum concentration curve (AUC) from time 0 to the last time point (AUC0-t) and peak concentration in serum (Cmax). The PK bioequivalence was confirmed using the standard equivalence margins of 80%-125%. The PK profiles of AK-HER2 and trastuzumab displayed high similarity. The geometric mean ratios (90% confidence intervals) of primary PK endpoints were within 80%-125%. The C max and AUC 0-t of female subjects in the AK-HER2 group were greater than those of male subjects (P <0.05). No infusion-related reactions (IRRs) or anti-drug antibody-positivity was observed after dosing. AK-HER2 was demonstrated to have highly similar PK to trastuzumab in healthy Chinese adults. Both drugs showed comparable safety and immunogenicity using dexamethasone as premedication to prevent IRRs..

description: We report on a search for the host galaxy of FRB171020, the fast radio burst with the smallest recorded dispersion measure (DM $=114$ pc cm$^{-3}$) of our on-ongoing ASKAP survey. The low DM confines the burst location within a sufficiently small volume to rigorously constrain the identity of the host galaxy. We identify 16 candidate galaxies in the search volume and single out ESO 601-G036, a Sc galaxy at redshift $z=0.00867$, as the most likely host galaxy. UV and optical imaging and spectroscopy reveal this galaxy has a star-formation rate of approximately 0.1 M$_\odot$ yr$^{-1}$ and oxygen abundance $12 + \log({\rm O/H}) = 8.3 \pm 0.2$, properties remarkably consistent with the galaxy hosting the repeating FRB121102. However, in contrast to FRB121102, follow-up radio observations of ESO 601-G036 show no compact radio emission above a 5$σ$ limit of $L_{2.1{\rm GHz}}=3.6\times 10^{19}$ W Hz$^{-1}$. Using radio continuum observations of the field, combined with archival optical imaging data, we find no analog to the persistent radio source associated with FRB121102 within the localization region of FRB171020 out to $z=0.06$. These results suggest that FRBs are not necessarily associated with a luminous and compact radio continuum source.

Relative entropy for compact Riemann surfaces

description: The relative entropy of the massive free bosonic field theory is studied on various compact Riemann surfaces as a universal quantity with physical significance, in particular, for gravitational phenomena. The exact expression for the sphere is obtained, as well as its asymptotic series for large mass and its Taylor series for small mass. One can also derive exact expressions for the torus but not for higher genus. However, the asymptotic behaviour for large mass can always be established-up to a constant-with heat-kernel methods. It consists of an asymptotic series determined only by the curvature, hence common for homogeneous surfaces of genus higher than one, and exponentially vanishing corrections whose form is determined by the concrete topology. The coefficient of the logarithmic term in this series gives the conformal anomaly.

description: A novel method for simulating the statistical mechanics of molecular systems in which both nuclear and electronic degrees of freedom are treated quantum mechanically is presented. The scheme combines a path integral description of the nuclear variables with a first-principles adiabatic description of the electronic structure. The electronic problem is solved for the ground state within a density functional approach, with the electronic orbitals expanded in a localized (Gaussian) basis set. The discretized path integral is computed by a Metropolis Monte Carlo sampling technique on the normal modes of the isomorphic ring-polymer. An effective short-time action correct to order $τ^4$ is used. The validity and performance of the method are tested in two small Lithium clusters, namely Li$_4$ and Li$_5^+$. Structural and electronic properties computed within this fully quantum-mechanical scheme are presented and compared to those obtained within the classical nuclei approximation. Quantum delocalization effects are significant but tunneling turns out to be irrelevant at low temperatures.

Local Interactions and Protein Folding: A Model Study on the Square and Triangular Lattices

description: We study a simple heteropolymer model containing sequence-independent local interactions on both square and triangular lattices. Sticking to a two-letter code, we investigate the model for varying strength $κ$ of the local interactions; $κ=0$ corresponds to the well-known HP model [K.F. Lau and K.A. Dill, Macromolecules 22, 3986 (1989)]. By exhaustive enumerations for short chains, we obtain all structures which act as a unique and pronounced energy minimum for at least one sequence. We find that the number of such designable structures depends strongly on $κ$. Also, we find that the number of designable structures can differ widely for the two lattices at a given $κ$. This is the case, for example, at $κ=0$, which implies that the HP model exhibits different behavior on the two lattices. Our findings clearly show that sequence-independent local properties of the chains can play an important role in the formation of unique minimum energy structures.

Rotating Bianchi type V dust models generalizing the k = -1 Friedmann model

Publisher: name: arXiv

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The Einstein equations for one of the hypersurface-homogeneous rotating dust models are investigated. It is a Bianchi type V model in which one of the Killing fields is spanned on velocity and rotation (case 1.2.2.2 in the classification scheme of the earlier papers). A first integral of the field equations is found, and with a special value of this integral coordinate transformations are used to eliminate two components of the metric. The k = -1 Friedmann model is shown to be contained among the solutions in the limit of zero rotation. The field equations for the simplified metric are reduced to 3 second-order ordinary differential equations that determine 3 metric components plus a first integral that algebraically determines the fourth component. First derivatives of the metric components are subject to a constraint (a second-degree polynomial with coefficients depending on the functions). It is shown that the set does not follow from a Lagrangian of the Hilbert type. The group of Lie point-symmetries of the set is found, it is two-dimensional noncommutative. Finally, a method of searching for first integrals (for sets of differential equations) that are polynomials of degree 1 or 2 in the first derivatives is applied. No such first integrals exist. The method is used to find a constraint (of degree 1 in first derivatives) that could be imposed on the metric, but it leads to a vacuum solution, and so is of no interest for cosmology.

description: The land-use characteristics of a watershed determined the amount of pollution produced in it, which can be curtailed by implementation of best management practices (BMPs) in an identified critical source area (CSA). Present and future land-use scenarios of the watershed were produced, and the hydrological simulation program FORTRAN model was used to model the hydrology and in-stream pollutants’ concentrations. The validated model was utilized to identify the CSA for diffuse total nitrogen, total phosphorus, sediment, and biochemical oxygen demand considering the two land-use scenarios. The results showed that CSA and the water quality index produced by the two land-use scenarios varied in each of the diffuse pollutants considered. It was observed that some portion of the identified CSA remains unchanged despite the changes in the land use and this was attributed to consistent urban development in these areas. The results in this study illustrate that BMPs can be included in the design and planning of future urban expansion based on the identified CSA derived from the expected future land-use changes. As anticipated, this approach will provide resilience on the effects of urbanization on the diffuse pollutants loads in a rapidly urbanized watershed.
