Variation in resistance and tolerance of black cottonwood to Melampsora occidentalis (Jacks) rust
Creators: name: Wang, Jun
Publisher: name: University of British Columbia
Year: 2011

description: Ramets of 14 clones of western black cottonwood Populus trichocarpa Torr. & Gray collected from the interior and coast of British Columbia were tested in the nursery for their growth performance after infection by the leaf rust Melampsora occidentalis Jacks. Linear relationships were demonstrated between various growth parameters (total dry weight, stem dry weight, root dry weight, volume, diameter and height) and disease severity rated as diseased leaf-weeks divided by total leaf-weeks. Losses due to rust infection included reduced total dry weight and volume growth in the year of heavy disease, the death of severely infected ramets during the following winter and reduced initial volume increment in the following growing season. The percentage reduction in yield (total dry weight) was greater than the cumulative percent leaf area infected, suggesting that the rust infected leaf parts act as sinks for photosynthate. The normal pattern of photosynthate allocation was altered in favour of the top growth of ramets. Ratios of stem/root dry weight increased rapidly as disease level increased. A threshold infection level, below which no loss occurred, was not detected in this pathosystem. Significant variation in rust resistance of black cottonwood clones was detected both within and between the two geographic areas. Clones from the coast or warm, moist areas were, on average, more resistant than clones from the interior or cold, dry climates. The phenomenon of induced resistance was not detected at either the local or the systemic levels in black cottonwood challenged by the rust. Variation in rust tolerance among black cottonwood clones was demonstrated. Rust tolerance was defined as the slope of the relationship between yield of ramets (expressed as a proportion of controls) and disease severity (expressed as the proportion of the total number of leaf-weeks infected). A negative correlation between rust tolerance and rust resistance was found. In the collection of clones tested, the positive effect of disease resistance on the growth of cottonwood clones was partially counterbalanced by the negative effect of reduced tolerance on the growth. The importance of this relationship in both natural and artificial selection of superior trees against disease is indicated.

description: We combine a limited number of accurately measured transition frequencies in hydrogen and deuterium, recent quantum electrodynamics (QED) calculations, and, as an essential additional ingredient, a generalized least-squares analysis, to obtain precise and optimal predictions for hydrogen and deuterium transition frequencies. Some of the predicted transition frequencies have relative uncertainties more than an order of magnitude smaller than that of the g-factor of the electron, which was previously the most accurate prediction of QED.

description: We study the radiative heat flux between two nanoparticles in close vicinity to the natural hyperbolic material hBN with its optical axis oriented parallel to the interface. We show that the heat flux between the nanoparticles can be efficiently modulated when rotating the nanoparticles due to the coupling to the highly directional hyperbolic surface modes in hBN. Finally, we discuss the thickness and distance dependence of this effect.
A geometric Birkhoffian formalism for nonlinear RLC networks

description: The aim of this paper is to give a formulation of the dynamics of nonlinear RLC circuits as a geometric Birkhoffian system and to discuss in this context the concepts of regularity, conservativeness, dissipativeness. An RLC circuit, with no assumptions placed on its topology, will be described by a family of Birkhoffian systems, parameterized by a finite number of real constants which correspond to initial values of certain state variables of the circuit. The configuration space and a special Pfaffian form, called Birkhoffian, are obtained from the constitutive relations of the resistors, inductors and capacitors involved and from Kirchhoff's laws. Under certain assumptions on the voltage-current characteristic for resistors, it is shown that a Birkhoffian system associated to an RLC circuit is dissipative. For RLC networks which contain a number of pure capacitor loops or pure resistor loops the Birkhoffian associated is never regular. A procedure to reduce the original configuration space to a lower dimensional one, thereby regularizing the Birkhoffian, it is also presented. In order to illustrate the results, specific examples are discussed in detail.

description: We construct a family of viable scalar-tensor models of dark energy (DE) which possess a phase of late-time acceleration preceded by a standard matter era, while at the same time satisfying the local gravity constraints (LGC). The coupling Q between the scalar field and the non-relativistic matter in the Einstein frame is assumed to be constant in our scenario, which is a generalization of f(R) gravity theories corresponding to the coupling Q=-1/sqrt{6}. We find that these models can be made compatible with local gravity constraints even when |Q| is of the order of unity through a chameleon mechanism, if the scalar-field potential is chosen to have a sufficiently large mass in the high-curvature regions. We show that these models generally lead to the divergence of the equation of state of DE, which occur at smaller redshifts as the deviation from the LambdaCDM model become more significant. We also study the evolution of matter density perturbations and employ them to place bounds on the coupling |Q| as well as model parameters of the field potential from observations of the matter power spectrum and the CMB anisotropies. We find that, as long as |Q| is smaller than the order of unity, there exist allowed parameter regions that are consistent with both observational and local gravity constraints.

description: Haiti is a country with a history of political instability and faces considerable challenges in attracting foreign direct investment (FDI). This study investigates the impact of political turmoil on FDI in Haiti from 1994 to 2020. The study relies on secondary data obtained from sources such as International Financial Statistics (IFS), World Development Indicators(WDI), and the International Country Risk Guide (ICRG). The study utilizes the Vector Error Correction Model (VECM) and the Dynamic Ordinary Least Squares (DOLS) statistical technique. The findings indicate that, over the long run, political instability and inflation have an adverse influence on FDI in Haiti. Conversely, exchange rate, interest rate, and trade openness positively affect FDI. However, these variables do not directly drive FDI in the short term but are influenced by external factors. This paper emphasizes the critical role of establishing a stable political environment, effectively managing inflation, and maintaining competitive exchange rates and interest rates to enhance FDI attraction. Additionally, promoting trade openness is deemed crucial.

description: We study the frontier between learnable and unlearnable hidden Markov models (HMMs). HMMs are flexible tools for clustering dependent data coming from unknown populations. The model parameters are known to be fully identifiable (up to label-switching) without any modeling assumption on the distributions of the populations as soon as the clusters are distinct and the hidden chain is ergodic with a full rank transition matrix. In the limit as any one of these conditions fails, it becomes impossible in general to identify parameters. For a chain with two hidden states we prove nonasymptotic minimax upper and lower bounds, matching up to constants, which exhibit thresholds at which the parameters become learnable. We also provide an upper bound on the relative entropy rate for parameters in a neighbourhood of the unlearnable region which may have interest in itself.

The problem is to classify the groups that can be written as bicrossed products between groups of fixed isomorphism types. The groups obtained as bicrossed products of two finite cyclic groups, one being of prime order, are described.

Curves of Marginal Stability in Two-Dimensional CP(N-1) Models with Z_N-Symmetric Twisted Masses

description: We consider curves of marginal stability (CMS) in CP(N-1) models in two dimensions with N = (2, 2) supersymmetry. In these theories, one can introduce twisted mass terms. The BPS spectrum has different number of states in the weak and strong coupling regimes. This spectral restructuring can be explained by the fact that two regimes are separated by CMS on which some BPS states decay. We focus on a special case of Z_N-symmetric twisted masses. In this case, the general solution due to Dorey greatly simplifies, and CMS can be found explicitly. For small-$N$ values numerical results are presented. In the large-N limit, we find CMS analytically up to ln N /N corrections.

description: Post-processing of analysis results is an integral part of a computer simulation of a structure (CAE) using the Finite Element Method (FEM). The goal of this dissertation is to design a automatic post-processing system, capable to fulfil current analysis model growing needs. In this dissertation the procedures that are used in the industrial field are studied. This way the problems are detected, and the characteristics of the modern finite element models, such as the size and the number of result files, are identified. Ways to enrich the available information to the engineer are examined closely, in order to improve the calculation possibilities and the visual representation of the results. Innovative ideas are proposed to accelerate the procedures using a solver's input file information, and automation is achieved with the creation of a script library for every analysis. Additionally this dissertation studies the modern graphics technologies and their application, in order to improve the visual quality of model results. Finally, techniques are proposed to compare the results of different model versions, and methodologies to correlate them with experimental data, something that leads to more accurate and faster evaluation of structural behaviour

description: We present the first resolved-star photometry of VV124 (UGC4879) and find that this is the most isolated dwarf galaxy in the periphery of the Local Group. Based on imaging and spectroscopic follow up observations with the 6m BTA telescope, we resolve VV124 into 1560 stars down to the limiting magnitude levels of V~25.6 and I~23.9. The young blue stellar populations and emission gas are found near the core, but noticeably displaced from the center of the galaxy as traced by dominant evolved red stars. The mean radial velocity derived from the spectra of two Blue Supergiant stars, an HII region and unresolved continuum sources is -80+/-10 km/s. The evolved ``red tangle'' stellar populations, which contains the red giant branch (RGB), are identified at large galactocentric radii. We use the I-band luminosity function to determine the distance based on the Tip of RGB method, 1.1+/-0.1 Mpc. This is ~10 times closer than the values usually assumed in the literature, and we provide revised distance dependent parameters. From the mean (V-I) color of the RGB, we estimate the mean metallicity as [Fe/H]~-1.37 dex. Despite of its isolated location, the properties of VV124 are clearly not those of a galaxy in formation, but rather similar to a transitional dIrr/dSph type.

description: We present an analysis of the X-ray emission of a large sample of z~3 Lyman break galaxies (LBGs), based on Chandra/ACIS observations of several LBG survey fields. 24 LBGs are directly detected in the X-ray. 13 of the LBGs have optical spectroscopic signatures of AGN activity, but almost all the other X-ray detections are also likely to host an accreting black hole based on their X-ray properties. The AGN exhibit a wide range in X-ray luminosity, from weak Seyferts to bright QSOs. Optical spectroscopy identified approximately 1/3 of the X-ray detected sources as broad line QSOs, 1/3 as narrow line AGN and 1/3 as normal star forming LBGs. The fraction of X-ray detected LBGs is 3%, much lower than has been found for submm selected galaxies. 2 galaxies have X-ray luminosities, spectra and f_x/f_opt values that are consistent with emission from star formation processes and are candidate X-ray bright, pure starburst galaxies at z~3. X-ray spectral analysis of the LBGs shows a mean photon index 1.96, similar to local AGN. There is evidence for absorption in at least 40% of the objects. Significantly more absorption is evident in the narrow line AGN, consistent with AGN unification schemes. After correction for absorption the narrow and broad line objects show the same average luminosity. LBGs spectroscopically classified as normal galaxies are less luminous in X-ray indicating that the host galaxy is outshining any optical AGN signature. For the LBGs without direct detections, stacking the X-ray flux in the 2 deepest fields under consideration (the HDF-N and GWS) produced significant detections in each. The detection in the HDF-N gives an X-ray derived SFR of 42.4+/-7.8 Msolar/yr per LBG and, by comparing with the UV SFR, the implied UV extinction correction is 4.1+/-0.8. (abridged)

description: String compactification with fluxes yields MSSM soft SUSY breaking terms that receive comparable contributions from modulus and anomaly mediation whose relative strength is governed by a phenomenological parameter $α$. Gaugino and first/second generation (and sometimes also Higgs and third generation) scalar mass parameters unify at a mirage unification scale $Q \not= M_{\rm GUT}$, determined by the value of $α$. The ratio of scalar to gaugino masses at this mirage unification scale depends directly on the scalar field modular weights, which are fixed in turn by the brane or brane intersections on which the MSSM fields are localized. We outline a program of measurements which can in principle be made at the CERN LHC and the International Linear $e^+e^-$ collider (ILC) which can lead to a determination of the modular weights.

Επιλέχθηκαν πέντε πληθυσμοί από δύο περιοχές της Νότιας Ελλάδας(Ναύπακτος και Ναύπλιο) που διέφεραν ως προς την πληθυσμιακή πυκνότητα και τις μικροκλιματικές συνθήκες.

Επίσης, σε ορισμένα από τα ζώα των δύο γενεών έγινε ιστολογική μελέτη της σπερματοθήκης. Από τα αποτελέσματα προέκυψε ότι οι μικροκλιματικές συνθήκες του ενδιαιτήματος τροποποιούν τη συζευκτική συμπεριφορά των σαλιγκαριών, μια και σε ξηρά ενδιατημικά ζώα τείνουν να συζεύγνυνται ταχύτερα και συχνότερα ώστε να επωφεληθούν από τις ευκαιριακές ευνοϊκές συνθήκες που παρουσιάζονται.

Also, in some of the animals of both generations, the complexity of the fertilization pouch(spermatheca), was studied histologically. The results showed that the microclimatic conditions of the habitat modify mating behaviour of snails, since animals from dry habitats tend to copulate more rapidly and more often, so as to benefit from the occasional favourable conditions prevailing. The fertilization pouch of H. apspersa presents a stable model, independent from the density, the microclimatic conditions and the mating behaviour in the populations

Extinction in the Large Magellanic Cloud

description: We present an extinction map of the Large Magellanic Cloud (LMC), using 204,502 stars from the Two Micron All Sky Survey point source catalog. We first use the NICE method to determine the reddening distribution, \ehk and \ejh, which we compare to the HI distribution to find a near-infrared reddening law of $\ejh/\ehk=1.20\pm 0.04$. A visual extinction map ($\sim 6^\circ\times 6^\circ$) of the LMC is created using the NICER method; at 4 arcmin resolution, a mean value of $\av=0.38$ mag is found. We derive the LMC CO-to-H$_2$ conversion factor, $\x{LMC}$, independent of assumptions about the virialization of giant molecular clouds, by comparing the NICER extinction map with NANTEN $^{12}$CO observations. In regions where $\av>1$ mag and $^{12}$CO emission is $\ge$ 2 \counits, we measure $\x{LMC}=9.3\pm 0.4\times 10^{20} \xunits$. In the same regions, the LMC contains a total molecular mass of $(4.5\pm 0.2)\times 10^7 \msun$.

description: Potential energy surfaces of the hydrogen molecular ion H$_2^+$ in the Born-Oppenheimer approximation are computed by means of the Riccati-Padé method (RPM). The convergence properties of the method are analyzed for different states. The equilibrium internuclear distance, as well as the corresponding electronic plus nuclear energy, and the associated separation constants, are computed to 40 digits of accuracy for several bound states. For the ground state the same parameters are computed with more than 100 digits of accuracy. Additional benchmark values of the electronic energy at different internuclear distances are given for several additional states. The software implementation of the RPM is given under a free software license. The results obtained in the present work are the most accurate available so far, and further additional benchmarks are made available through the software provided.

description: We analyze a 96 ks Chandra/HETGS observation of the single G-type giant HR 9024. The high flux allows us to examine spectral line and continuum diagnostics at high temporal resolution, to derive plasma parameters. A time-dependent 1D hydrodynamic model of a loop with half-length $L = 5 \times 10^{11}$ cm ($\sim R_{\star}/2$), cross-section radius $r = 4.3 \times 10^{10}$ cm, with a heat pulse of 15 ks and $2 \times 10^{11}$~erg cm$^{-2}$ s$^{-1}$ deposited at the loop footpoints, satisfactorily reproduces the observed evolution of temperature and emission measure, derived from the analysis of the strong continuum emission. For the first time we can compare predictions from the hydrodynamic model with single spectral features, other than with global spectral properties. We find that the model closely matches the observed line emission, especially for the hot ($\sim 10^8$ K) plasma emission of the FeXXV complex at $\sim 1.85$Å. The model loop has $L/R_{\star} \sim 1/2$ and aspect ratio $r/L \sim 0.1$ as typically derived for flares observed in active stellar coronae, suggesting that the underlying physics is the same for these very dynamic and extreme phenomena in stellar coronae independently on stellar parameters and evolutionary stage.

Part I. Coral Limestone and Its Use. Part II. Chemical Stabilization of Coral Surfaces

description: I. Coral Limestone and Its Use

Limestone of coral origin was abundantly used for construction
of Military and Naval bases in the Pacific during World War II.
Its use was almost always spectacularly successful and contributed
largely to the successful operations against the Japanese Empire.
Nevertheless a rigid analysis of the coral used reveals it to be a
rather poor material. This study briefly reviews the theoretical
concepts of the origin of coral deposits and describes the nature of
the various types of deposits. From this a guide is established to
assist the construction engineer in finding the coral he needs, sometimes
a difficult problem.

The characteristics of coral deposits are explained and a
method of processing the coral for desirable results is given, along
with the reasons for the method. A logical explanation for the
"setting up" phenomena is established.

II. Chemical Stabilization of Coral Surfaces

The possibility of chemical stabilization of the top surface
of coral bases to prevent dust is explored. The process involved is
analysed and an order of magnitude of quantities determined. The
necessary experiments to prove the process and tentative field procedures
are outlined.

Correlated errors can lead to better performance of quantum codes

Publisher: name: arXiv
Year: 2007
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: A formulation for evaluating the performance of quantum error correcting codes for a general error model is presented. In this formulation, the correlation between errors is quantified by a Hamiltonian description of the noise process. We classify correlated errors using the system-bath interaction: local versus nonlocal and two-body versus many-body interactions. In particular, we consider Calderbank-Shor-Steane codes and observe a better performance in the presence of correlated errors depending on the timing of the error recovery. We also find this timing to be an important factor in the design of a coding system for achieving higher fidelities.

description: Στην εκπόνηση της συγκεκριμένης διατριβής οδήγησε η έλλειψη μελετών των Καλών Τεχνών κατά τη διάρκεια της πρώιμης, ιδιάζουσας καλλιτεχνικής και πνευματικής ζωής της Θεσσαλονίκης. Ερευνήθηκαν και απαντήθηκαν τα ερωτήματα που αφορούσαν στην πορεία των εικαστικών τεχνών πρωτίστως, οι οποίες πάντως εξετάστηκαν μέσα στο ευρύτερο πλαίσιο των τεχνών-αρχιτεκτονικής, λογοτεχνίας, μουσικής, θεάτρου, κινηματογράφου-λόγω των αλληλεπιδράσεων που παρατηρήθηκαν, διαμορφώνοντας αισθητικές τάσεις και κριτήρια κατά τη διάρκεια της πιο πολυκύμαντης περιόδου της ιστορίας της Θεσσαλονίκης 1912-1967. Ζητήματα που εκκεμούσαν λόγω απουσίας μονογραφιών, επιμερισμένης, συχνά εξωραϊσμένης θεώρησης του καλλιτεχνικού φαινομένου, αντιμετωπίστηκαν ολοκληρωμένα, συνθετικά, σε σχέση με τα ιστορικά, κοινωνικοπολιτικά γεγονότα, το ειδικό και γενικό καλλιτεχνικό κλίμα της πόλης. Περιοδολόγηση βασιζόμενη στα ιστορικά γεγονότα, γραμμική παρακολούθηση της δημόσιας παρουσίασης των τεχνών, με αξιοκρατικά πάντα κριτήρια, έμφαση στις τομές, τους θεσμούς, τις παλινδρομήσεις, τη στασιμότητα, την ακμή ή και την παρακμή του παραγόμενου έργου, η καλλιτεχνική δημιουργία διερευνήθηκε σε σχέση με τις ιδιότυπες συνθήκες διαμόρφωσης και λειτουργίας του αστικού χώρου
description: The present thesis arose out of a need to redress the lack of available studies on the Fine Arts during the early phase of the dinstinctive artistic and cultural life of modern Thessaloniki. The thesis deals mainly with questions relating to the development of the visual arts, though these have been examined in the context of the arts in general-architecture, literature, music, theatre, cinema-because of the cross-influence between them, which helped ti shape aesthetic trends and criteria during the most eventful period in Thessaloniki's history, the period 1912-1967. Issues that had long been unresolved due to a lack of monographs and a selective, often prettified treatment of the artistic phenomenon have been dealt with in a comprehensive and synthetic manner, with reference to historical and socio-political events and the city;s general and special artistic climate. Artistic developments are examined in chronological order, based on the sequence of historical events. The study provides a linear treatment of the public presentation of the arts-always based on meritocratic criteria-and highlights the major developements and institutions in the city's artistic life, as well as its regressive tendencies, stagnation and periods of prosperity and decline. Furthermore, it examines artistic creation in relation to the peculiar conditions of the city's urban development and manner of operation

description: We demonstrate experimentally a read-out method that distinguishes between two-electron spin states in a quantum dot. This scheme combines the advantages of the two existing mechanisms for spin-to-charge conversion with single-shot charge detection: a large difference in energy between the two states and a large difference in tunnel rate between the states and a reservoir. As a result, a spin measurement fidelity of 97% was achieved, which is much higher than previously reported fidelities.
