description: A possible discrepancy has been found between the results of a neutron interferometry experiment and Quantum Mechanics. This experiment suggests that the weak equivalence principle is violated at small length scales, which quantum mechanics cannot explain. In this paper, we investigated whether the Generalized Uncertainty Principle (GUP), proposed by some approaches to quantum gravity such as String Theory and Doubly Special Relativity Theories (DSR), can explain the violation of the weak equivalence principle at small length scales. We also investigated the consequences of the GUP on the Liouville theorem in statistical mechanics. We have found a new form of invariant phase space in the presence of GUP. This result should modify the density states and affect the calculation of the entropy bound of local quantum field theory, the cosmological constant, black body radiation, etc. Furthermore, such modification may have observable consequences at length scales much larger than the Planck scale. This modification leads to a \sqrt{A}-type correction to the bound of the maximal entropy of a bosonic field which would definitely shed some light on the holographic theory.

description: We communicate results on correlation functions for the spin-1/2 Heisenberg-chain in two particularly important cases: (a) for the infinite chain at arbitrary finite temperature $T$, and (b) for finite chains of arbitrary length $L$ in the ground-state. In both cases we present explicit formulas expressing the short-range correlators in a range of up to seven lattice sites in terms of a single function $ω$ encoding the dependence of the correlators on $T$ ($L$). These formulas allow us to obtain accurate numerical values for the correlators and derived quantities like the entanglement entropy. By calculating the low $T$ (large $L$) asymptotics of $ω$ we show that the asymptotics of the static correlation functions at any finite distance are $T^2$ ($1/L^2$) terms. We obtain exact and explicit formulas for the coefficients of the leading order terms for up to eight lattice sites.

On the Spaces and Dimensions of Geographical Systems

Publisher: name: arXiv
Year: 2011
Subjects: subject: Physics and Society (physics.soc-ph)
subject: FOS: Physical sciences

description: To remove the confusion of concepts about different sorts of geographical space and dimension, a new framework of space theory is proposed in this paper. Based on three sets of fractal dimensions, the geographical space is divided into three types: real space (R-space), phase space (P-space), and order space (O-space). The real space is concrete or visual space, the fractal dimension of which can be evaluated through digital maps or remotely sensed images. The phase space and order space are both abstract space, the fractal dimension values of which cannot be estimated with one or two maps or images. The dimension of phase space can be computed by using time series, and that of order space can be determined with cross-sectional data in certain time. Three examples are offered to illustrate the three types of spaces and fractal dimension of geographical systems. The new space theory can be employed to explain the parameters of geographical scaling laws, such as the scaling exponent of the allometric growth law of cities and the fractal dimension based on Horton's laws of rivers.

description: Penetrable Square Wells in one dimension were introduced for the first time in [A. Santos et. al., Phys. Rev. E, 77, 051206 (2008)] as a paradigm for ultra-soft colloids. Using the Kastner, Schreiber, and Schnetz theorem [M. Kastner, Rev. Mod. Phys., 80, 167 (2008)] we give strong evidence for the absence of any phase transition for this model. The argument can be generalized to a large class of model fluids and complements the van Hove's theorem.

description: The fully quantized model of double qubits coupled to a common bath is solved using the quantum state diffusion (QSD) approach in the non-Markovian regime. We have established the explicit time-local non-Markovian QSD equations for the two-qubit dissipative and dephasing models. Diffusive quantum trajectories are applied to the entanglement estimation of two-qubit systems in a non-Markovian regime. In both cases, non-Markovian features of entanglement evolution are revealed through quantum diffusive unravellings in the system state space.

description: Using infrared photometry from the Spitzer Space Telescope, we perform the first inventory of aromatic feature emission (AFE, but also commonly referred to as PAH emission) for a statistically complete sample of star-forming galaxies in the local volume. The photometric methodology involved is calibrated and demonstrated to recover the aromatic fraction of the IRAC 8 micron flux with a standard deviation of 6% for a training set of 40 SINGS galaxies (ranging from stellar to dust dominated) with both suitable mid-infrared Spitzer IRS spectra and equivalent photometry. A potential factor of two improvement could be realized with suitable 5.5 and 10 micron photometry, such as what may be provided in the future by JWST. The resulting technique is then applied to mid-infrared photometry for the 258 galaxies from the Local Volume Legacy (LVL) survey, a large sample dominated in number by low-luminosity dwarf galaxies for which obtaining comparable mid-infrared spectroscopy is not feasible. We find the total LVL luminosity due to five strong aromatic features in the 8 micron complex to be 2.47E10 solar luminosities with a mean volume density of 8.8E6 solar luminosities per cubic Megaparsec. Twenty-four of the LVL galaxies, corresponding to a luminosity cut at M = -18.22 in the B band, account for 90% of the aromatic luminosity. Using oxygen abundances compiled from the literature for 129 of the 258 LVL galaxies, we find a correlation between metallicity and the aromatic to total infrared emission ratio but not the aromatic to total 8 micron dust emission ratio. A possible explanation is that metallicity plays a role in the abundance of aromatic molecules relative to the total dust content, but other factors such as star formation and/or the local radiation field affect the excitation of those molecules.

Exploring Shortest Paths on Large-Scale Networks
Creators: name: Wang, Ye
Publisher: name: The Australian National University
Year: 2022

description: Networks, which are gaining much popularity in various disciplines, model connec-tions between different real-world entities. Based on graph theory, we gain insightinto a series of problems for understanding networks. Shortest path is among themost fundamental notions studied in graph theory. By exploring shortest path struc-ture, we can better understand the connections between entities. However, it is oftencomputationally expensive to compute shortest paths on large-scale networks whichare common nowadays.This thesis addresses two problems on large-scale networks in relating to shortestpaths: (1) How are two vertices connected in a graph? We first define the notion ofshortest path graph which contains exactly all shortest paths between two vertices.This notion empowers us to make full use of shortest path structures for analysingthe connection between vertices. We formalize the shortest-path-graph problem andpropose a novel method, called Query-by-Sketch, which can efficiently leverage of-fline labelling to guide online searching through a fast-sketching process for solvingthe shortest-path-graph problem on complex networks. (2) How is one source vertexconnected to other vertices in a graph? Enumerating all shortest paths between a source vertex and all other vertices is less informative due the fact that the number of shortest paths is excessive. In addition to this, coverage centrality fails to measure how influ-ential a vertex is in the information flow from a source vertex. Thus we extend thenotion of coverage centrality to relative coverage, to measure the importance a vertexis w.r.t a source vertex. Then we formalize the top-k relative coverage problem anddevelop an efficient method to answer top-k relative coverage queries in a reducedspace, and design a bit-parallel optimization to speed up the computation of relativecoverage.The thesis also theoretically discusses the complexity of proposed methods, andpresents the experimental results of proposed methods using 12 and 6 real-worlddatasets for two problems respectively, which illustrates the efficiency and scalabilityof proposed metho

We prove that $$\sum_{k=0}^{p-1}\binom{-1/(p+1)}k^{p+1}\equiv 0\ \pmod{p^5}\ \ \ \mbox{and}\ \ \ \sum_{k=0}^{p-1}\binom{1/(p-1)}k^{p-1}\equiv \frac{2}{3}p^4B_{p-3}\ \pmod{p^5},$$ where $B_0,B_1,B_2,\ldots$ are Bernoulli numbers. We also show that for any $a\in\mathbb Z$ with $p\nmid a$ we have $$\sum_{k=1}^{p-1}\frac1k\left(1+\frac ak\right)^k\equiv -1\pmod{p}\ \ \ \mbox{and}\ \ \ \sum_{k=1}^{p-1}\frac1{k^2}\left(1+\frac ak\right)^k\equiv 1+\frac 1{2a}\pmod{p}.$$

A magnetic field evolution scenario for brown dwarfs and giant planets

description: Very little is known about magnetic fields of extrasolar planets and brown dwarfs. We use the energy flux scaling law presented by Christensen et al. (2009) to calculate the evolution of average magnetic fields in extrasolar planets and brown dwarfs under the assumption of fast rotation, which is probably the case for most of them. We find that massive brown dwarfs of about 70 M_Jup can have fields of a few kilo-Gauss during the first few hundred Million years. These fields can grow by a factor of two before they weaken after deuterium burning has stopped. Brown dwarfs with weak deuterium burning and extrasolar giant planets start with magnetic fields between ~100G and ~1kG at the age of a few Myr, depending on their mass. Their magnetic field weakens steadily until after 10Gyr it has shrunk by about a factor of 10. We use observed X-ray luminosities to estimate the age of the known extrasolar giant planets that are more massive than 0.3M_Jup and closer than 20pc. Taking into account the age estimate, and assuming sun-like wind-properties and radio emission processes similar to those at Jupiter, we calculate their radio flux and its frequency. The highest radio flux we predict comes out as 700mJy at a frequency around 150MHz for $τ$Boob, but the flux is below 60mJy for the rest. Most planets are expected to emit radiation between a few Mhz and up to 100MHz, well above the ionospheric cutoff frequency.

description: We present the first unambiguous evidence of a broad (Gaussian width ~330 eV) component of the iron K-alpha fluorescent emission line in the X-ray obscured Narrow Line Seyfert 1 Galaxy NGC5506. This is the main results of a spectroscopic monitoring campaign on this source performed with the XMM-Newton observatory between February 2001 and January 2009. The broad line lacks extreme redwards skewness. If modelled with a relativistic component, the profile of the line is consistent with a flat emissivity radial dependence (alpha~1.9). The disk inclination (~40 degrees) is nominally larger then typically observed in unobscured AGN, in agreement with most measurements of broadened iron lines in Seyfert 2 galaxies. The quality of the data allows us to decompose the full iron emission line complex, and to study its long-term (timescales of weeks to years) variability pattern. The intensity of the neutral and narrow iron K-alpha core remains constant during the monitoring campaign. This indicates that the optically thick gas responsible for the non-relativistic reprocessing of the primary AGN continuum in NGC5506 is probably located in the torus rather than in the optical Broad Line Region.

Our simulations are performed at a lattice cutoff of $1/a$=2.0 GeV in a spatial volume of $(3\;\text{fm})^3$ with the nonperturbatively $O(a)$ improved Wilson action for the light quarks and a relativistic heavy quark action for the charm quark. We have found that the potential $V_{c\bar{c} N}(r)$ is weakly attractive at short distance and exponentially screened at long distance.

description: Let $G$ be a connected nilpotent Lie group. Given probability-preserving $G$-actions $(X_i,Σ_i,μ_i,u_i)$, $i=0,1,...,k$, and also polynomial maps $ϕ_i:\mathbb{R}\to G$, $i=1,...,k$, we consider the trajectory of a joining $λ$ of the systems $(X_i,Σ_i,μ_i,u_i)$ under the `off-diagonal' flow \[(t,(x_0,x_1,x_2,...,x_k))\mapsto (x_0,u_1^{ϕ_1(t)}x_1,u_2^{ϕ_2(t)}x_2,...,u_k^{ϕ_k(t)}x_k).\] It is proved that any joining $λ$ is equidistributed under this flow with respect to some limit joining $λ'$. This is deduced from the stronger fact of norm convergence for a system of multiple ergodic averages, related to those arising in Furstenberg's approach to the study of multiple recurrence. It is also shown that the limit joining $λ'$ is invariant under the subgroup of $G^{k+1}$ generated by the image of the off-diagonal flow, in addition to the diagonal subgroup.

description: Doppler cooling the center-of-mass motion of an optically levitated microsphere via the velocity dependent scattering force from narrow whispering gallery mode (WGM) resonances is described. Light that is red detuned from the WGM resonance can be used to damp the center-of-mass motion in a process analogous to the Doppler cooling of atoms. Leakage of photons out of the microsphere when the incident field is near resonant with the narrow WGM resonance acts to damp the motion of the sphere. The scattering force is not limited by saturation, but can be controlled by the incident power. Cooling times on the order of seconds are calculated for a 20 micron diameter silica microsphere trapped within optical tweezers, with a Doppler temperature limit in the microKelvin regime.

description: Siamo nel 2015, molti degli stati europei appartenenti all’Unione Europea hanno concesso i diritti egualitari anche alle coppie omosessuali. È dagli anni ‘90 ad oggi che sono stati ottenuti i maggiori progressi in merito; infatti sono pochi ormai gli stati membri che non hanno regolamentato le unioni civili, i matrimoni o le adozioni per coppie di omosessuali. Eppure siamo nel 2015 anche in Italia, ma al contrario della maggior parte degli stati della comunità europea, in questo paese il traguardo sembra ancora lontano e impossibile da raggiungere. In questi ultimi anni si è provato a proporre leggi contro l’omofobia o sulle unioni civili, ma purtroppo senza alcun risultato. Oggi in Parlamento si sta forse muovendo qualcosa, dopo ciò che è successo in Irlanda e negli Stati Uniti, è stata rilanciata la proposta delle unioni civili. Con la speranza accesa di poter arrivare ad avere una legge che dia la possibilità alle coppie gay di ottenere alcuni dei diritti tanto desiderati, è nata l’esigenza di capire perché l’Italia sia sempre stata restia a dare questi diritti che nel resto d’Europa sembra siano scontati.

description: Come è possibile rendere l’incontro con un’orchestra sinfonica una reale attività di educazione all’ascolto? Partendo da questa domanda, durante un periodo di tirocinio presso la scuola elementare di Chiasso tra marzo e aprile 2013, è stato progettata, organizzata, gestita e verificata una ricerca-azione che, muovendo dalle recenti teorie psico-cognitive e pedagogiche relative all’educazione all’ascolto, ispirandosi al paradigma dell’educazione dinamica proposto da Carlo Delfrati, ha condotto gli allievi di tre classi di quarta e quinta elementare a sviluppare le competenze (strutturale, linguistica, culturale), il tipo di ascolto (tassonomico) e le motivazioni necessarie per vivere uno dei Concerti per le scuole dell’Orchestra della Svizzera Italiana in maniera più approfondita rispetto ai loro coetanei. Essi, infatti, sono stati stimolati ad adottare comportamenti che consentono la costruzione di una rappresentazione multidimensionale della musica, grazie a metodologie che coinvolgono la relazionalità, il movimento, l’immedesimazione e la multisensorialità.

description: The bachelor's work is devoted to the development of a web portal for storing specifications in the LibSL language. The web portal being developed can be used to simplify software development when using third-party libraries, by considering the behavior ofsoftware libraries. The paper highlights modern approaches to creating a web application. Based on the studied approaches, we developed our own approach to creating a web portal with the necessary criteria for working with specifications in the LibSL language. Based on this approach, a web service was implemented,and the resulting tool was tested, which showed the performance of the web portal. In the future, we plan to develop the web application and develop additional features.

Using GIT we contruct a coarse moduli space for $δ$-semistable pairs $(\mathcal{E},ϕ)$ consisting of a coherent sheaf $\mathcal{E}$ and a homomorphism $ϕ\colon \mathcal{D}\rightarrow \mathcal{E}$. We prove a chamber structure result and establish a connection to the moduli space of coherent systems constructed by Le Potier in \cite{LeP} and \cite{LeP2}.

On the Quantitative Impact of the Schechter-Valle Theorem

description: We evaluate the Schechter-Valle (Black Box) theorem quantitatively by considering the most general Lorentz invariant Lagrangian consisting of point-like operators for neutrinoless double beta decay. It is well known that the Black Box operators induce Majorana neutrino masses at four-loop level. This warrants the statement that an observation of neutrinoless double beta decay guarantees the Majorana nature of neutrinos. We calculate these radiatively generated masses and find that they are many orders of magnitude smaller than the observed neutrino masses and splittings. Thus, some lepton number violating New Physics (which may at tree-level not be related to neutrino masses) may induce Black Box operators which can explain an observed rate of neutrinoless double beta decay. Although these operators guarantee finite Majorana neutrino masses, the smallness of the Black Box contributions implies that other neutrino mass terms (Dirac or Majorana) must exist. If neutrino masses have a significant Majorana contribution then this will become the dominant part of the Black Box operator. However, neutrinos might also be predominantly Dirac particles, while other lepton number violating New Physics dominates neutrinoless double beta decay. Translating an observed rate of neutrinoless double beta decay into neutrino masses would then be completely misleading. Although the principal statement of the Schechter-Valle theorem remains valid, we conclude that the Black Box diagram itself generates radiatively only mass terms which are many orders of magnitude too small to explain neutrino masses. Therefore, other operators must give the leading contributions to neutrino masses, which could be of Dirac or Majorana nature.

Valence particles and the correction to relativistic mean field binding energy

Subjects: subject: Nuclear Theory (nucl-th)

description: The differences between the experimental and the theoretically calculated binding energies in Relativistic Mean Field (RMF) approach have been calculated for a large number of odd-$Z$ nuclei from $A=47$ to 229. Neutron-proton (n-p) interaction is expected to be the major contributor to this difference. This difference, excluding certain mass regions and taking other effects as well as the odd-even mass difference into account, may be linearly parametrized by the Casten factor, a recognized measure of the n-p interaction in the nucleus. The results follow the same pattern as in the case of even-$Z$ nuclei observed earlier.
Resilience enhancement for interdependent critical infrastructures
Creators: name: Yang, Zejun
Publisher: name: University of British Columbia
Year: 2020

description: Modern societies depend on the proper and resilient functioning of their critical infrastructures (CIs) to support quality of life to their population. The interdependencies of the CI systems, however, make the CIs increasingly vulnerable to several threats; as a result, natural or human-made disasters can cause significant physical, economic, and social disruptions. Since total beforehand protection cannot be guaranteed, CI protection strategies should focus on resilience enhancement at both the pre- and the post-disaster phase for a better response. This thesis first proposes a resilience assessment framework that provides quantitative means to assess infrastructure resilience for interdependent CI systems. The framework is tested within the Infrastructure Interdependencies Simulator (i2SIM) that models and simulates the CI interdependencies. A coupled Cyber-Physical System (CPS) is modelled within the i2SIM framework to study the process of cascading failures. Resilience enhancement for the pre-disaster preparedness is done with a risk evaluation approach and is proposed by considering the profile of a hurricane to calculate the probability of failure of the network components. Based on the results of the evaluation, a resource allocation optimization is formulated using mixed-integer nonlinear programming (MINLP). For post-disaster resilience enhancement, an optimal reconfiguration algorithm, together with a hybrid load shedding strategy, is developed to find alternative paths to maintain supply to the most critical loads. A modified shortest path search that we call the Optimal Recovery Sequencing (ORS) is used to optimize the repair sequences. The obtained numerical results validate that the recovery ability of the coupled system, and as a result its resilience, is increased with the proposed optimization. Finally, to reduce the computational complexity for very large scenarios and for real-time response, this thesis uses a Soft-Hard Optimal Convergence (SHOC) methodology. Machine learning techniques are used to train an artificial intelligence (AI) agent with thousands of off-line scenarios to provide the initial estimate for the SHOC algorithm. After the disaster occurs, hard optimization methods are used on a small subset of solutions identified by the AI agent. Using this methodology, solution time speedups of 800 times for a 70-bus test system with 30 simultaneous faults are achieved.
Blaschke products and nonideal ideals in higher order Lipschitz algebras

description: We investigate certain ideals (associated with Blaschke products) of the analytic Lipschitz algebra $A^α$, with $α>1$, that fail to be "ideal spaces". The latter means that the ideals in question are not describable by any size condition on the function's modulus. In the case where $α=n$ is an integer, we study this phenomenon for the algebra $H^\infty_n=\{f:f^{(n)}\in H^\infty\}$ rather than for its more manageable Zygmund-type version. This part is based on a new theorem concerning the canonical factorization in $H^\infty_n$.

description: Although property rights have been used to understand numerous wildlife issues, such as extinctions, they have rarely been used to provide insights into specific management options. We present analytical frameworks that may be used to characterize property rights to wildlife for the purpose of understanding the implications of management actions for various stakeholders. The frameworks consider multiple types of values, including consumptive, non-consumptive, and passive-use values. Our case study involves the emergence of Chronic Wasting Disease (CWD) and its potential influence on the rights of stakeholders (i.e. the general public and hunters) in Alberta, Canada. Populating the framework for each stakeholder with characteristics of current property rights allow us to identify: 1) how the emergence of CWD could influence stakeholders’ current rights, 2) how management actions could change property rights and associated incentives; and 3) management options that have not been considered.

description: This study aims to propose an extended model of the theory of planned behavior (TPB) which helps us to investigate young Chinese consumers from college and university, and who are aged 18 to 30 years, on purchase intention for organic food. Using a sample of 515, analyses were done using structural equation modeling. The findings indicated that attitude (A), subjective norms (SNs), and perceived behavioral control (PBC) have positive effects on the purchase intention of young consumers for organic food. Moreover, attitude has a positive effect on environmental concerns (EC). Furthermore, EC has a positive effect on young consumers’ purchase intentions for organic food. Findings indicated that EC positively mediates the association between attitude and young consumers’ purchase intentions for organic food. More importantly, the relationship between all latent variables (A, SNs, PBC) and purchase intention by young consumers is positively moderated by environmental awareness.

description: The Void Galaxy Survey (VGS) is a multi-wavelength program to study $\sim$60 void galaxies. Each has been selected from the deepest interior regions of identified voids in the SDSS redshift survey on the basis of a unique geometric technique, with no a prior selection of intrinsic properties of the void galaxies. The project intends to study in detail the gas content, star formation history and stellar content, as well as kinematics and dynamics of void galaxies and their companions in a broad sample of void environments. It involves the HI imaging of the gas distribution in each of the VGS galaxies. Amongst its most tantalizing findings is the possible evidence for cold gas accretion in some of the most interesting objects, amongst which are a polar ring galaxy and a filamentary configuration of void galaxies. Here we shortly describe the scope of the VGS and the results of the full analysis of the pilot sample of 15 void galaxies.

description: The effect of epitaxial strain on the phonon spectra, crystal structure, spontaneous polarization, dielectric, piezoelectric, and elastic properties of (001)-oriented ferroelectric (BaTiO$_3$)$_m$/(SrTiO$_3$)$_n$ superlattices ($m = n = {}$1-4) was studied using the first-principles density-functional theory. The ground state of free-standing superlattices is the monoclinic $Cm$ polar phase. Under the in-plane biaxial compressive strain, it transforms to tetragonal $P4mm$ polar phase, and under the in-plane biaxial tensile strain, it transforms to orthorhombic $Amm2$ polar phase. When changing the in-plane lattice parameter, a softening of several optical and acoustic modes appears at the boundaries between the polar phases, and corresponding components of dielectric, piezoelectric, and elastic tensors diverge critically. The comparison of the mixing enthalpy of disordered Ba$_{0.5}$Sr$_{0.5}$TiO$_3$ solid solution modeled using two special quasirandom structures SQS-4 with the mixing enthalpy of the superlattices reveals a tendency of the BaTiO$_3$-SrTiO$_3$ system to short-range ordering and shows that these superlattices are thermodynamically quite stable.

description: Road verges could provide habitats for threatened grassland species, but current verge management is suboptimal for achieving this. Altering verge management to favor grassland species is possible but depends on stakeholder attitudes and valuation. We describe the attitudes of 373 Finnish road verge stakeholders toward grassland-friendly verge management and investigate the drivers underlying these attitudes. We also assess the perceived feasibility of different grassland-friendly management alterations and identify barriers facing their implementation. Gathered with online questionnaires, the data for the study comprises open-ended and Likert scale questions and was analyzed with multivariate methods and linear mixed models. According to the results, valued verge attributes, such as perceived species-richness and safety, and personal familiarity with biodiversity and semi-natural grasslands structure stakeholder attitudes toward grassland-friendly management. Specific management alterations, such as readjusted mowing schedules, are viewed with varying positivity, but insufficient resources and compromised traffic safety are perceived to hinder their implementation.
