Structural property relationships for Canadian dimension lumber
Creators: name: Liliefna, Leonard Dantje
Publisher: name: University of British Columbia
Year: 2009

description: Lumber property data from Canadian In-Grade Program for visually-graded dimension lumber are used to model lumber property relationships. The lumber properties studied are modulus of elasticity (MOE), modulus of rupture (MOR), ultimate tensile stress parallel to the grain (UTS), and ultimate compression stress parallel to the grain (UCS) for Douglas-fir, Hem-Fir and Spruce-Pine-Fir species groups. Structural property relationships based on three different approaches using Canadian dimension lumber have been modeled. The nonlinear models were adopted for the general stiffness-strength property relationships. The fitted regression models for the general stiffhess-strength property relationships then were used to model the strength property relationships. Band-width method was used to derive the relationships between modulus of elasticity and lower exclusion limits of strength values. The fitted models then were used to model the strength property relationships. The resulted models represent the relationship between two strength properties at the lower exclusion limit for lumber selected on the basis of modulus of elasticity. The strength property relationships derived using equal-rank method agree with that derived using general stiffness-strength property relationships. Therefore, for lumber selected on the basis of modulus of elasticity, the models derived using equal-rank method yield an average or mean trend for the estimated properties. The results of the analysis show that there exist good relationships between lumber strength properties. The strength property ratios for Canadian dimension lumber show significant species dependency particularly at the higher strength level. Property relationships trends are consistent across the species and methods of analyses. The property ratio models are intended to provide property estimates of characteristic values for untested properties. The property ratios for Canadian dimension lumber are significantly higher than that proposed by the American Society for Testing and Materials (ASTM) standard D 1990.
Gramsci: the Democratic Philosopher

description: Peter Thomas's The Gramscian Moment provides a definitive rebuttal of Perry Anderson's and Louis Althusser's influential critiques of the work of Antonio Gramsci. Throughout the course of the book, which ranges from discussions of the literary form of the Prison Notebooks to explications of the concepts of 'passive revolution' and the 'integral state' he demonstrates that Gramsci's work is characterized by 'absolute historicism', 'absolute immanence' and 'absolute humanism'. Hegemony, that is, constitutes a 'metaphysical event' or a 'philosophical fact': the passage between these last two conceptions delineates the 'Gramscian moment' of 1931-1932.

description: Automatic extraction of medical conditions from free-text radiology reports is critical for supervising computer vision models to interpret medical images. In this work, we show that radiologists labeling reports significantly disagree with radiologists labeling corresponding chest X-ray images, which reduces the quality of report labels as proxies for image labels. We develop and evaluate methods to produce labels from radiology reports that have better agreement with radiologists labeling images. Our best performing method, called VisualCheXbert, uses a biomedically-pretrained BERT model to directly map from a radiology report to the image labels, with a supervisory signal determined by a computer vision model trained to detect medical conditions from chest X-ray images. We find that VisualCheXbert outperforms an approach using an existing radiology report labeler by an average F1 score of 0.14 (95% CI 0.12, 0.17). We also find that VisualCheXbert better agrees with radiologists labeling chest X-ray images than do radiologists labeling the corresponding radiology reports by an average F1 score across several medical conditions of between 0.12 (95% CI 0.09, 0.15) and 0.21 (95% CI 0.18, 0.24).

description: In the present work the contribution of forest maps and forest cadaster in the protection and sustainable management of forest ecosystems and their biodiversity is being studied. The concepts of forest ecosystem, biodiversity, forest map and forest cadaster are analyzed and their interrelationships are being examined. The role of forest ecosystems to face serious environmental problems such as climate change, desertification and water cycle, is considered unreplaceable. The definition of forest - forest land, it is a critical point for the compilation of forest maps and forest cadaster. The role of forest maps and forest cadaster are demonstrated: a) in the protection of forest ecosystems and their biodiversity from pressures and disasters due to human activities (violations, deforestations, land use change), but also b) in safeguarding of the real state forest property, thus contributing to the planning of right forest policy and also in the creation of safe environment in making over of the real properties. And finally, recommendations are provided under the frame of the creation of an updated forest cadaster

description: We study the level statistics of an interacting multi-qubit system, namely the kicked Ising spin chain, in the regime of quantum chaos. Long range quasi-energy level statistics show effects analogous to the ones observed in semi-classical systems due to the presence of classical periodic orbits, while short range level statistics display perfect statistical agreement with random matrix theory. Even though our system possesses no classical limit, our result suggest existence of an important non-universal system specific behavior at short time scale, which clearly goes beyond finite size effects in random matrix theory.

Our theory takes into account charge-renormalization of the colloidal interactions and volume terms due to many-body effects. For valencies as small as Z=1 and as large as $10^4$ we find a gas--liquid spinodal instability in the colloid-salt phase diagram provided $Z\lB/a\gtrsim24\pm1$, where $\lB$ is the Bjerrum length.

description: Many new results on hadron spectra have been appearing in the past few years thanks to improved experimental techniques and searches in new channels. New theoretical techniques including refined methods of lattice QCD have kept pace with these developments. Much has been learned about states made of both light (u, d, and s) and heavy (c, b) quarks. The present review treats light-quark mesons, glueballs, hybrids, particles with a single c or b quark, charmonium, and bottomonium states. Some prospects for further study are noted.

description: Evolution of the cosmic star formation rate (SFR) and molecular gas mass density is expected to be matched by a similarly strong evolution of the fraction of atomic hydrogen (HI) in the cold neutral medium (CNM). We use results from a recent commissioning survey for intervening 21-cm absorbers with the Australian Square Kilometre Array Pathfinder (ASKAP) to construct a Bayesian statistical model of the $N_{\rm HI}$-weighted harmonic mean spin temperature ($T_{\rm s}$) at redshifts between $z = 0.37$ and $1.0$. We find that $T_{\rm s} \leq 274$K with 95 per cent probability, suggesting that at these redshifts the typical HI gas in galaxies at equivalent DLA column densities may be colder than the Milky Way interstellar medium ($T_{\rm s, MW} \sim 300$K). This result is consistent with an evolving CNM fraction that mirrors the molecular gas towards the SFR peak at $z \sim 2$. We expect that future surveys for HI 21-cm absorption with the current SKA pathfinder telescopes will provide constraints on the CNM fraction that are an order of magnitude greater than presented here.

description: In an effort to study the applicability of adaptive mesh refinement (AMR) techniques to atmospheric models an interpolation-based spectral element shallow water model on a cubed-sphere grid is compared to a block-structured finite volume method in latitude-longitude geometry. Both models utilize a non-conforming adaptation approach which doubles the resolution at fine-coarse mesh interfaces. The underlying AMR libraries are quad-tree based and ensure that neighboring regions can only differ by one refinement level. The models are compared via selected test cases from a standard test suite for the shallow water equations. They include the advection of a cosine bell, a steady-state geostrophic flow, a flow over an idealized mountain and a Rossby-Haurwitz wave. Both static and dynamics adaptations are evaluated which reveal the strengths and weaknesses of the AMR techniques. Overall, the AMR simulations show that both models successfully place static and dynamic adaptations in local regions without requiring a fine grid in the global domain. The adaptive grids reliably track features of interests without visible distortions or noise at mesh interfaces. Simple threshold adaptation criteria for the geopotential height and the relative vorticity are assessed.

Within the mean field theory approximation, our study of the solitonic dynamics shows that the solitonic wave function, its center of mass motion, and the local spin evolutions are stable and are intimately related to the domain structures studied recently in spin-1 $^{87}$Rb condensates. We discuss a rotating reference frame wherein the dynamics of the solitonic local spatial spin distribution become time independent.

While formal valence counting would imply this material to be an undoped insulator, it is a self-doped superconductor with a Tc of 60K, possessing simultaneously both electron- and hole-doped FS sheets. Intriguingly, the FS sheet characterized by the much larger gap is the electron-doped one, which has a shape disfavoring two electronic features considered to be important for the pairing mechanism: the van Hove singularity and the antiferromagnetic (Pi/a, Pi/a) scattering.

description: Quasicrystals exhibit long-range order but lack translational symmetry. When grown as single crystals, they possess distinctive and unusual properties owing to the absence of grain boundaries. Unfortunately, conventional methods such as bulk crystal growth or thin film deposition only allow us to synthesize either polycrystalline quasicrystals or quasicrystals that are at most a few centimeters in size. Here, we reveal through real-time and 3D imaging the formation of a single decagonal quasicrystal arising from a hard collision between multiple growing quasicrystals in an Al-Co-Ni liquid. Through corresponding molecular dynamics simulations, we examine the underlying kinetics of quasicrystal coalescence and investigate the effects of initial misorientation between the growing quasicrystalline grains on the formation of grain boundaries. At small misorientation, coalescence occurs following rigid rotation that is facilitated by phasons. Our joint experimental-computational discovery paves the way toward fabrication of single, large-scale quasicrystals for novel applications.

description: We consider the Rosenfeld-Groebner algorithm for computing a regular decomposition of a radical differential ideal generated by a set of ordinary differential polynomials in n indeterminates. For a set of ordinary differential polynomials F, let M(F) be the sum of maximal orders of differential indeterminates occurring in F. We propose a modification of the Rosenfeld-Groebner algorithm, in which for every intermediate polynomial system F, the bound M(F) is less than or equal to (n-1)!M(G), where G is the initial set of generators of the radical ideal. In particular, the resulting regular systems satisfy the bound. Since regular ideals can be decomposed into characterizable components algebraically, the bound also holds for the orders of derivatives occurring in a characteristic decomposition of a radical differential ideal. We also give an algorithm for converting a characteristic decomposition of a radical differential ideal from one ranking into another. This algorithm performs all differentiations in the beginning and then uses a purely algebraic decomposition algorithm.

description: In recent years, dynamical phase transitions and out-of-equilibrium criticality have been at the forefront of ultracold gases and condensed matter research. Whereas universality and scaling are established topics in equilibrium quantum many-body physics, out-of-equilibrium extensions of such concepts still leave much to be desired. Using exact diagonalization and the time-dependent variational principle in uniform martrix product states, we calculate the time evolution of the local order parameter and Loschmidt return rate in transverse-field Ising chains with antiferromagnetic power law-decaying interactions, and map out the corresponding rich dynamical phase diagram. \textit{Anomalous} cusps in the return rate, which are ubiquitous at small quenches within the ordered phase in the case of ferromagnetic long-range interactions, are absent within the accessible timescales of our simulations in the antiferromagnetic case, showing that long-range interactions are not a sufficient condition for their appearance. We attribute this to much weaker domain-wall binding in the antiferromagnetic case. For quenches across the quantum critical point, \textit{regular} cusps appear in the return rate and connect to the local order parameter changing sign, indicating the concurrence of two major concepts of dynamical phase transitions. Our results consolidate conclusions of previous works that a necessary condition for the appearance of anomalous cusps in the return rate after quenches within the ordered phase is for topologically trivial local spin flips to be the energetically dominant excitations in the spectrum of the quench Hamiltonian. Our findings are readily accessible in modern trapped-ion setups, and we outline the associated experimental considerations.

description: We analyse the metallicity histories of ~4,500 galaxies from the GAMA survey at z<0.06 modelled by the SED-fitting code ProSpect using an evolving metallicity implementation. These metallicity histories, in combination with the associated star formation histories, allow us to analyse the inferred gas-phase mass--metallicity relation. Furthermore, we extract the mass--metallicity relation at a sequence of epochs in cosmic history, to track the evolving mass--metallicity relation with time. Through comparison with observations of gas-phase metallicity over a large range of redshifts, we show that, remarkably, our forensic SED analysis has produced an evolving mass--metallicity relationship that is consistent with observations at all epochs. We additionally analyse the three dimensional mass--metallicity--SFR space, showing that galaxies occupy a clearly defined plane. This plane is shown to be subtly evolving, displaying an increased tilt with time caused by general enrichment, and also the slowing down of star formation with cosmic time. This evolution is most apparent at lookback times greater than 7 Gyr. The trends in metallicity recovered in this work highlight that the evolving metallicity implementation used within the SED fitting code ProSpect produces reasonable metallicity results over the history of a galaxy. This is expected to provide a significant improvement to the accuracy of the SED fitting outputs.

description: Let $m\in\mathbb N_{\ge 2}$, and let $\mathcal K=\{K_λ: λ\in(0, 1/m]\}$ be a class of Cantor sets, where $K_λ=\{\sum_{i=1}^\infty d_iλ^i: d_i\in\{0,1,\ldots, m-1\}, i\ge 1\}$. We investigate in this paper the likelyhood of a fixed point in the Cantor sets of $\mathcal K$. More precisely, for a fixed point $x\in(0,1)$ we consider the parameter set $Λ(x)=\{λ\in(0,1/m]: x\in K_λ\}$, and show that $Λ(x)$ is a topological Cantor set having zero Lebesgue measure and full Hausdorff dimension. Furthermore, by constructing a sequence of Cantor subsets with large thickness in $Λ(x)$ we prove that the intersection $Λ(x)\capΛ(y)$ also has full Hausdorff dimension for any $x, y\in(0,1)$.

An alternate approach to simulate the dynamics of perturbed liquid drops

description: Liquid drops when subjected to external periodic perturbations can execute polygonal oscillations. In this work, a simple model is presented that demonstrates these oscillations and their characteristic properties. The model consists of a spring-mass network such that the masses are analogous to liquid molecules and the springs are to intermolecular forces. Neo-Hookean springs are considered to represent these intermolecular forces. The restoring force of a neo-Hookean spring depends nonlinearly on its length such that the force of a compressed spring is much higher than the force of a spring elongated by the same amount. This is equivalent to the incompressibility of liquids, making these springs suitable to simulate the polygonal oscillations. It is shown that this spring-mass network can imitate most of the characteristic features of experimentally reported polygonal oscillations. Additionally, it is shown that the network can execute certain dynamics which so far have not been observed in a perturbed liquid drop. The features of dynamics which are observed in the perturbed network are: polygonal oscillations, rotation of network, numerical relations (rational and irrational) between the frequencies of polygonal oscillations and the forcing signal, and the dependency of the shape of the polygons on the parameters of perturbation.

description: Here we present the entropic dynamics formalism for networks. That is, a framework for the dynamics of graphs meant to represent a network derived from the principle of maximum entropy and the rate of transition is obtained taking into account the natural information geometry of probability distributions. We apply this framework to the Gibbs distribution of random graphs obtained with constraints on the node connectivity. The information geometry for this graph ensemble is calculated and the dynamical process is obtained as a diffusion equation. We compare the steady state of this dynamics to degree distributions found on real-world networks.

description: In this paper we show that a quadratic lagrangian, with no constraints, containing ordinary time derivatives up to the order $m$ of $N$ dynamical variables, has $2mN$ symmetries consisting in the translation of the variables with solutions of the equations of motion. We construct explicitly the generators of these transformations and prove that they satisfy the Heisenberg algebra. We also analyse other specific cases which are not included in our previous statement: the Klein-Gordon lagrangian, $N$ Fermi oscillators and the Dirac lagrangian. In the first case, the system is described by an equation involving partial derivatives, the second case is described by Grassmann variables and the third shows both features. Furthermore, the Fermi oscillator and the Dirac field lagrangians lead to second class constraints. We prove that also in these last two cases there are translational symmetries and we construct the algebra of the generators. For the Klein-Gordon case we find a continuum version of the Heisenberg algebra, whereas in the other cases, the Grassmann generators satisfy, after quantization, the algebra of the Fermi creation and annihilation operators.

Ethical Issues in Empirical Studies using Student Subjects: Re-visiting Practices and Perceptions

description: Context: Using student subjects in empirical studies has been discussed extensively from a methodological perspective in Software Engineering (SE), but there is a lack of similar discussion surrounding ethical aspects of doing so. As students are in a subordinate relationship to their instructors, such a discussion is needed. Objective: We aim to increase the understanding of practices and perceptions SE researchers have of ethical issues with student participation in empirical studies. Method: We conducted a systematic mapping study of 372 empirical SE studies involving students, following up with a survey answered by 100 SE researchers regarding their current practices and opinions regarding student participation. Results: The mapping study shows that the majority of studies does not report conditions regarding recruitment, voluntariness, compensation, and ethics approval. In contrast, the majority of survey participants supports reporting these conditions. The survey further reveals that less than half of the participants require ethics approval. Additionally, the majority of participants recruit their own students on a voluntary basis, and use informed consent with withdrawal options. There is disagreement among the participants whether course instructors should be involved in research studies and if should know who participates in a study. Conclusions: It is a positive sign that mandatory participation is rare, and that informed consent and withdrawal options are standard. However, we see immediate need for action, as study conditions are under-reported, and as opinions on ethical practices differ widely. In particular, there is little regard in SE on the power relationship between instructors and students.

description: We determine the phase diagram and the momentum distribution for a one-dimensional Bose gas with repulsive short range interactions in the presence of a two-color lattice potential, with incommensurate ratio among the respective wave lengths, by using a combined numerical (DMRG) and analytical (bosonization) analysis. The system displays a delocalized (superfluid) phase at small values of the intensity of the secondary lattice V2 and a localized (Bose glass-like) phase at larger intensity V2. We analyze the localization transition as a function of the height V2 beyond the known limits of free and hard-core bosons. We find that weak repulsive interactions unfavor the localized phase i. e. they increase the critical value of V2 at which localization occurs. In the case of integer filling of the primary lattice, the phase diagram at fixed density displays, in addition to a transition from a superfluid to a Bose glass phase, a transition to a Mott-insulating state for not too large V2 and large repulsion. We also analyze the emergence of a Bose-glass phase by looking at the evolution of the Mott-insulator lobes when increasing V2. The Mott lobes shrink and disappear above a critical value of V2. Finally, we characterize the superfluid phase by the momentum distribution, and show that it displays a power-law decay at small momenta typical of Luttinger liquids, with an exponent depending on the combined effect of the interactions and of the secondary lattice. In addition, we observe two side peaks which are due to the diffraction of the Bose gas by the second lattice. This latter feature could be observed in current experiments as characteristics of pseudo-random Bose systems.

description: In questo studio viene proposta una ricostruzione comparativa del nome del popolo progenitore degli Sciti: i *Sagatas, di cui si deduce la traduzione nel greco *Σαγέται, Sageti.  Viene inoltre formulata la derivazione del nome *Sagatas dal termine *Swagautas, a cui si attribuisce il significato di “allevatori di vacche”, facendolo a sua volta derivare da *swagaus, composto che può significare “vacca addomesticata” o “mandria”, o dalla sua derivazione *swagauna, “foraggio”. Viene poi presentata una ricostruzione del carattere religioso dei Sageti, confrontato con quello dei popoli affini. Viene infine proposta, sulla base di un’analisi dei toponimi, degli etnonimi e delle testimonianze storiche, una ricostruzione delle migrazioni dei Sageti dalla loro terra di origine, le praterie a Nord della Sogdiana, verso il resto dell’Asia e l’Europa, riconoscendo la loro discendenza nelle popolazioni dei due continenti, dagli Ascaloni ai Balti e dai Caledoni ai Kusana e agli Ainu.

After providing some background on Eznik’s views on the origin of evil and free will as they are argued for in his treatise Refutation of the Sects, the article reviews the history of the interpretation of a passage in this work (Eznik, I, 11 [§ 45]), giving a critical assessment of the suggested emendations so far, and proposing two hypothetical readings, based on a comparison of the Armenian text with its supposed Greek Vorlage, the text’s transmission history, and internal contextual analysis.

Dynamics of Rarefaction Waves in General-Relativistic Collapsing Clouds

Subjects: subject: Astrophysics (astro-ph)

description: Formation and evolution of general relativistic collapse inhomogeneity is investigated. It is shown that a rarefaction wave forms at initial collapse stages and propagates inside from the cloud boundary to its center. The focusing time of the rarefaction wave is found. In massive clouds, the rarefaction wave focusing time equals the free-fall time. The collapse of such clouds leads to black hole formation. In low-mass clouds, the rarefaction wave focusing time is less than the free-fall time. After focusing, the collapse of such clouds becomes fully inhomogeneous and can be sufficiently decelerated by the pressure gradient.

description: L’obiettivo posto in questo contributo è quello di analizzare i discorsi prodotti dalla voce del popolo e da quella dei candidati intorno alle elezioni europee 2014 in Francia, per rintracciare i legami che intercorrono tra esse. L’approccio lessicometrico ha consentito di congiungere i dati numerici raccolti nel corpus di rifermento, incentrato sulla produzione discorsiva della voce del popolo, con l’analisi vera e propria dei discorsi politici. Attraverso un percorso che va quindi dai dati analizzati in senso numerico e quantitativo, all’osservazione empirica dell’uso effettivo dei discorsi e della loro circolazione, in questo articolo si vuole dimostrare la presenza di richiami, rinvii e rimandi continui tra le voci in esame. Due sono i punti chiave dell’analisi qui presentata: uno studio dell’espressione della soggettività da parte dei protagonisti dei discorsi e un’indagine dei modi di
stabilizzazione degli stessi attraverso l’osservazione delle tracce linguistiche dell’interdiscorsività.
A Little-Known Dah-nāma: ʿAishī’s ʿIshrat-nāma

description:

The present article offers an edition of the single known manuscript of ʿAishī Shīrāzī’s ʿIshrat-nāma in the Bibliothèque Nationale in Paris, Suppl. Persan 1142 (nr. 1642 in the catalogue of Blochet), a poem belonging to the mathnawī genre dah-nāma. In this genre, the evolution of the relationship of two lovers up to their union is described through their exchange of ten letters or, as is also the case here, ten verbal messages. It is argued that it was written between 874/1470 and 882/1478, namely, at the time of Aq-Quyūnlū Khalīl b. Uzun Ḥasan, during his governorship of Fārs, some seventy years later than Blochet’s estimate. This is the first of two articles about this poem. The second article, in which the messengers – ten different musical instruments who convey the messages between the lovers – shall be discussed, will be published in the next issue.

description: We introduce a new method permitting the analytical determination of entanglement entropy (and related quantities) between configurations of a quantum field, which is either free or in interaction with a classical source, at two distinct spatial locations. We show how such a setup can be described by a bipartite, continuous Gaussian system. This allows us to derive explicit and exact formulas for the entanglement entropy, the mutual information and the quantum discord, solely in terms of the Fourier-space power spectra of the field. This contrasts with previous studies, which mostly rely on numerical considerations. As an illustration, we apply our formalism to massless fields in flat space, where exact expressions are derived that only involve the ratio between the size of the regions over which the field is coarse-grained, and the distance between these regions. In particular, we recover the well-known fact that mutual information decays as the fourth power of this ratio at large distances, as previously observed in numerical works. Our method leads to the first analytical derivation of this result, and to an exact formula that also applies to arbitrary distances. Finally, we determine the quantum discord and find that it identically vanishes (unless coarse-graining is performed over smeared spheres, in which case it obeys the same suppression at large distance as mutual information).

description: We study QED corrections to the chiral symmetry breaking in Nambu-Jona-Lasinio (NJL) model with two flavors of quarks. In the model the isospin symmetry is broken by differences of the current quark masses and the electromagnetic charges between up and down quarks. In the leading order of the 1/N expansion we calculate the effective potential of the model with one-loop QED corrections. Evaluating the effective potential, we study an influence of the isospin symmetry breaking on the orientation of chiral symmetry breaking. The current quark mass has an important contribution for the orientation of chiral symmetry breaking.

description: We propose single-step additive fabrication of graded-index optical elements by introducing the light exposure as the additional dimension to three-dimensional (3D) laser writing, hence (3+1)D writing. We use a commercial printer and photoresist to realize the proposed single step fabrication method that can be swiftly adopted for research and engineering. After presenting the characterization of the graded-index profiles via basic structures, we demonstrate two different optical devices: volume holograms that are superimposed using angular and peristrophic multiplexing, and optical waveguides with well-defined refractive index profiles. In the latter, we precisely control the propagating modes via tuning the (3+1)D-printed waveguide parameters and report step-index and graded-index core-cladding transitions.
