description: In recent experiments by Richardson et al. ((2010), PLoS ONE 5(3): e9621. doi:10.1371/ journal.pone.0009621) ant motion out of the nest is shown to be a non-stationary process intriguingly similar to the dynamics encountered in \emph{physical aging} of glassy systems. Specifically, exit events can be described as a Poisson process in logarithmic time, or, for short, a log-Poisson process. Nouvellet et al.(J. Theor. Biol. 266, 573. (2010)) criticized these conclusions and performed new experiments where the exit process could more simply be described by standard Poisson statistics. In their reply, (J Theor. Biol. 269, 356-358 (2011)) Richardson et al. stressed that the two sets of experiments were performed under very different conditions and claimed that this was the likely source of the discrepancy. The focal point of this work is whether log-Poisson and Poisson statistics both are possible under different external conditions. To this end, a model is introduced where interacting ants move in a stochastic fashion from one site to a neighboring site on a finite 2D lattice. The probability of each move is determined by the ensuing changes of a utility function which is a sum of pairwise interactions between ants, weighted by distance. Depending on how the interactions are defined and on a control parameter dubbed 'degree of stochasticity' (DS), the dynamics either quickly converges to a stationary state, where movements are a standard Poisson process, or may enter a non-stationary regime, where exits can be described as suggested by Richardson et al.

Performance-based seismic design and assessment of concrete bridge piers reinforced with high-strength steel rebar
Creators: name: Aldabagh, Saif Maad
Publisher: name: University of British Columbia
Year: 2021

description: Utilizing high-strength steel (HSS) rebars in concrete bridge columns in seismic applications is greatly restricted primarily due to the lack of appropriate seismic design guidelines. The purpose of this study is to use a combination of analytical and experimental methods to evaluate the seismic performance of concrete bridge columns reinforced with HSS rebars, and thereby make appropriate design recommendations. ASTM A1035 Grade 690 steel was the primary focus of this study, however, other types of HSS were also considered in a number of assessments for comparison purposes. In this study, a comprehensive analytical program with an overarching objective of proposing simplified expressions to predict drift ratio limit states for circular concrete columns reinforced with HSS was first carried out. A machine learning-based symbolic regression was used to fit the resulting data into simplified numerical expressions. The proposed simplified expression provided adequate predictions of the drift ratio limit states obtained from the numerical analysis as well as those measured in previous experimental programs. In addition, a comprehensive experimental study was carried out to examine the low-cycle fatigue performance of ASTM A1035 Grade 690 rebars under cyclic-strain reversals. Existing strain and energy-based fatigue-life models’ constants were calibrated using the generated experimental fatigue data. Previously established low-cycle fatigue life models of HSS rebars were utilized as a part of an analytical program to identify conditions under which such rebars can achieve adequate performance in comparison to that of benchmark ASTM A706 Grade 420 steel bars in concrete bridge columns. Irrespective of the spacing-to-bar diameter ratio, ASTM A1035 Grade 690 rebars demonstrated adequate low-cycle fatigue performance for crustal earthquakes up to a displacement ductility level of 2. Design codes were found overly restrictive in not permitting the use of HSS in seismic applications based on their low-cycle fatigue performance. Lastly, analytical seismic fragility curves were developed for a concrete bridge pier alternately reinforced with HSS and conventional normal-strength steel. Comparisons between fragility curves were made to evaluate the applicability of certain clauses of the Canadian Highway Bridge Design Code to bridge piers reinforced with HSS.

description: We measure elastomechanical spectra for a family of thin shells. We show that these spectra can be described by a "semiclassical" trace formula comprising periodic orbits on geodesics, with the periods of these orbits consistent with those extracted from experiment. The influence of periodic orbits on spectra in the case of two-dimensional curved geometries is thereby demonstrated, where the parameter corresponding to Planck's constant in quantum systems involves the wave number and the curvature radius. We use these findings to explain the marked clustering of levels when the shell is hemispherical.

These are the Schreier graphs associated with the action of two well-known self-similar groups acting on the binary rooted tree by automorphisms: the first Grigorchuk group of intermediate growth, and the iterated monodromy group of the complex polynomial $z^2-1$ known as the Basilica group. For both of them, we describe the Tutte polynomial and we compute several special evaluations of it, giving further information about the combinatorial structure of these graphs.

description: Monochromatic photons could be produced in the annihilation or decay of dark matter particles. At high energies, the search for such line features in the cosmic gamma-ray spectrum is essentially background free because plausible astrophysical processes are not expected to produce such a signal. The observation of a gamma-ray line would hence be a `smoking-gun' signature for dark matter, making the search for such signals particularly attractive. Among the different dark matter models predicting gamma-ray lines, the local supersymmetric extension of the standard model with small R-parity violation and gravitino LSP is of particular interest because it provides a framework where primordial nucleosynthesis, gravitino dark matter and thermal leptogenesis are naturally consistent. Using the two-years Fermi LAT data, we present a dedicated search for gamma-ray lines coming from dark matter annihilation or decay in the Galactic halo. Taking into account the full detector response, and using a binned profile likelihood method, we search for significant line features in the energy spectrum of the diffuse flux observed in different regions of the sky. No evidence for a line signal at the 5-sigma level is found for photon energies between 1 and 300 GeV, and conservative bounds on dark matter decay rates and annihilation cross sections are presented. Implications for gravitino dark matter in presence of small R-parity violation are discussed, as well as the impact of our results on the prospect for seeing long-lived neutralinos or staus at the LHC.

description: We show how the path-integral formulation of quantum statistical mechanics can be used to construct practical {\em ab initio} techniques for computing the chemical potential of molecules adsorbed on surfaces, with full inclusion of quantum nuclear effects. The techniques we describe are based on the computation of the potential of mean force on a chosen molecule, and generalise the techniques developed recently for classical nuclei. We present practical calculations based on density functional theory with a generalised-gradient exchange-correlation functional for the case of H$_2$O on the MgO~(001) surface at low coverage. We note that the very high vibrational frequencies of the H$_2$O molecule would normally require very large numbers of time slices (beads) in path-integral calculations, but we show that this requirement can be dramatically reduced by employing the idea of thermodynamic integration with respect to the number of beads. The validity and correctness of our path-integral calculations on the H$_2$O/MgO~(001) system are demonstrated by supporting calculations on a set of simple model systems for which quantum contributions to the free energy are known exactly from analytic arguments.

description: Chronic kidney disease of undetermined aetiology (CKDu) is mainly responsible for the deaths of young males in agricultural lowland regions of Central America. The aim of this thesis was to advance the understanding of the causes of CKDu by conducting several different epidemiological research studies. The systematic review identified a number of cross-sectional studies and occupational cohort studies with limited follow-up periods, but the findings were inconclusive regarding the causes of CKDu. The cohort study described in this PhD thesis is the first community-based cohort study in the region to evaluate the natural history of disease in apparently healthy people aged 18-30 years. It collected information about a wide range of exposure conditions with a questionnaire, biological samples, and water samples. There was an unparalleled, asymptomatic and very rapid decline in renal function among 10% of males and 3.5% of females who had normal renal function at baseline. Meanwhile, the group displaying established renal dysfunction (mean estimated glomerular filtration rate, eGFR: 58 mL/min/1.73 m2) at baseline showed a slower subsequent decline in kidney function (3.6 mL/min/1.73 m2/year). A rapid decrease in eGFR was associated with outdoor work, agricultural work, and a lack of shade during work breaks. The nested case-control study measured eGFR, and urinary neutrophil gelatinase-associated lipocalin (uNGAL) at baseline. After adjusting for eGFR, uNGAL did not improve prediction a rapid decline in kidney function among individuals who initially presented a normal eGFR. This is the first study to show that in northwest Nicaragua, 10% of the male and 3.5% of the female population aged 18-30 years showed a very strong decline in kidney function. Larger community-based and occupational longitudinal studies with more detailed analyses of exposure data are needed to identify the cause(s) of CKDu.

description: This final qualification work is devoted to the priority movement of urban electric transport in the city of St. Petersburg. The paper considered the possibility of organizing the priority movement of urban electric transport on the example of tram route â39. To solve the problem, an approach was chosen to introduce adaptive management and the use of technical means of traffic management. The target indicator defines the travel time of public transport. The application of the approach is demonstrated by the example of three intersections of roadways. PTV Vissim has developed models of the considered sections of the road network.

description: We study a stochastic process $X_t$ related to the Bessel and the Rayleigh processes, with various applications in physics, chemistry, biology, economics, finance and other fields. The stochastic differential equation is $dX_t = (nD/X_t) dt + \sqrt{2D} dW_t$, where $W_t$ is the Wiener process. Due to the singularity of the drift term for $X_t = 0$, different natures of boundary at the origin arise depending on the real parameter $n$: entrance, exit, and regular. For each of them we calculate analytically and numerically the probability density functions of first-passage times or first-exit times. Nontrivial behaviour is observed in the case of a regular boundary.

description: Oggigiorno viviamo in una società sempre più confrontata con le nuove tecnologie e i media. Tutto ciò ha delle ripercussioni anche sul mondo dei più piccoli, i quali entrano in possesso di modelli di gestione dei conflitti non idonei e perlopiù basati sulla violenza. Il lavoro di docente richiede una particolare attenzione anche allo sviluppo personale di ogni singolo bambino, con lo scopo di accompagnarli tutti verso una maggiore autonomia e presa di decisioni ragionevoli. Per garantire di avere in futuro adulti responsabili e inclini all’uso della pace, è necessario fornir loro dei validi supporti per far fronte a situazioni difficoltose. Nel percorso inerente a questa tesi di Bachelor gli alunni si sono confrontati con i principi dell’apprendimento cooperativo e dell’educazione socio-emotiva. Gli allievi sono stati incoraggiati costantemente a riconoscere, nominare e gestire le proprie emozioni, con l’intento di identificare i propri bisogni e necessità. Inoltre si sono misurati con alcuni strumenti per la gestione nonviolenta dei conflitti. L’intero percorso ha permesso loro di realizzare un progetto condiviso. Quest’ultimo si è basato sul concetto di identità competente, la quale ha permesso agli alunni di riflettere sulle proprie peculiarità, con lo scopo di metterle a disposizione del gruppo. I dati raccolti e le numerose discussioni hanno permesso di evidenziare un’evoluzione in positivo della classe e di dimostrare quanto sia importante promuovere questi concetti.

description: Agroclimatic conditions of the Yakutia and the limiting factors constraining of potato productivity enlargement are considered. Problems and prospects of breeding work on a potato in the Yakutia are shown. The article summarizes the results of studies assessing potato hybrids economically valuable traits, resistance to most common diseases and the keeping quality according to the accepted scheme of selection in the arid conditions of cry ozone. As pollinators, 14 varieties of early and middle early groups of ripeness with high economic efficiency were used. Twenty combinations of crossing with 15 maternal forms were carried out. The most effective pollinators by the results of hybridization were the varieties Latona, Yakutyanka, Breeze, from the mother forms Rosalind, Adretta, Kamensky and Rosara. Because of breeding works, new promising hybrids of 232 (Aurora x Bonus), 233 (Slavyanka x Rosalind) were obtained with an average yield of 27.7 t / ha, potential 42.0 t / ha, with excellent taste. Evaluation of these hybrids will continue. Based on these studies the grade Aldan 117 1 (720.131 x Spring (white)) was suggested, which is transferred to the Russian State Commission for Testing and Protection of New Varieties of Plants from the Yakut State Research Institute of Agriculture named after M.G. Safronov. The characteristics of potato varieties of local breeding, created in accordance with the priority areas for the region of breeding, included in the State Register of Breeding Achievements of the Russian Federation and protected by patents are also given.

description: We investigated the relationship between the X-ray variability amplitude and X-ray luminosity for a sample of 14 bright Ultra-luminous X-ray sources (ULXs) with XMM-Newton/EPIC data, and compare it with the well established similar relationship for Active Galactic Nuclei (AGN). We computed the normalised excess variance in the 2-10 keV light curves of these objects and their 2-10 keV band intrinsic luminosity. We also determined model "variability-luminosity" relationships for AGN, under several assumptions regarding their power-spectral shape. We compared these model predictions at low luminosities with the ULX data. The variability amplitude of the ULXs is significantly smaller than that expected from a simple extrapolation of the AGN "variability-luminosity" relationship at low luminosities. We also find evidence for an anti-correlation between the variability amplitude and L(2-10 keV) for ULXs. The shape of this relationship is consistent with the AGN data but only if the ULXs data are shifted by four orders of magnitudes in luminosity. Most (but not all) of the ULXs could be "scaled-down" version of AGN if we assume that: i) their black hole mass and accretion rate are of the order of ~(2.5-30)x 10E+03 Msolar and ~ 1-80 % of the Eddington limit, and ii) their Power Spectral Density has a doubly broken power-law shape. This PDS shape and accretion rate is consistent with Galactic black hole systems operating in their so-called "low-hard" and "very-high" states.

description: The article presents the results of field studies on the biological production of fodder crops in cryolithozone conditions for the production of green frozen food. The purpose of the research is to study the yield, nutritional value and productivity of oats, and its mixtures with peas, rapeseed and barley at different sowing times for cryofeed. Field experiments were conducted on permafrost floodplain sod-gley soils of the Oymyakonsky District (Cold Pole) of the Republic of Sakha (Yakutia). Laboratory studies were performed on the basis of the laboratory of biochemistry and mass analysis (GOST-26205-86). In Oymyakon, the duration of the period with an average daily temperature above 10 degrees is equal to 73 days on average. The transition of the average daily air temperature through + 10 degrees occurs in August, after + 5 in September, the sum of active temperatures above +10 degrees is 913 degrees Celsius, which allows cultivation of cold-resistant feed crops for cryofeed. The highest crop of forage crops in an average of 3 years of research was obtained by the second term of sowing. Oats provided the maximum yield of green mass 10.6 t/ha. The yield of the green mass of the oatmeal mixture was 10.2 t/ha, the oats + barley provided 9.5 t/ha of the green mass. The oatmeal mixture has the lowest yield of green mass 6.4 t/ha, which is explained by the biological features of the plants. In terms of productivity, the highest rates were noted for oats the gross energy collection for the second term was 48.4 GJ/ha, the exchange energy was 28.2 GJ/ha, and the digestible protein was 0.36 t/ha. The oat-pea mixture provided the maximum yield of feed-protein units for the second sowing period — 0.64 t/ha, while the gross energy was 46.5 GJ/ha, the exchange energy was 25.0 GJ/ha, and the digestible protein was 0.49 t/ha, dry weight yield was 2.7 t/ha. A distinctive feature of the production of cryofeed is that the sowing of forage crops is carried out not in spring, but in mid-July (the second term of sowing), with the calculation of the remaining amount of active temperatures 650-700 degrees Celsius sufficient for the accumulation of high yield of green mass (6.4-10.6 t/ha) by the time of transition of average daily air temperature through +5 degrees to minus. The production of frozen by natural cold green fodder based on the late date of sowing annual forage crops in permafrost conditions will provide for the need of feed protein and animal vitamins of the North in the winter-spring period.

description: The article examines investment opportunities in agriculture, in terms of the food security. Investment highlights as well as the basic risks are defined. Low output profitability, outstanding debt liabilities of the agricultural organizations, differentiation of the agricultural investment opportunities on the area basis as well as differentiation of the companies providing services within the industry according to their ability to raise the external funds are considered to be the principal risks for the Smolensk Region. Based on the state control and regulation pattern in agriculture, there were defined actions to be taken in order to improve investment opportunities in agriculture this is a budgetary financing of priority sectors. The key farming sector in the Smolensk Region is considered to be dairy cattle breeding: according to the estimated and forecasted development, it is possible to expand the cow population by more than 20 % and to practically double the amount of milk produced by using high technologies. The support of investors will lead to better infrastructure development, including storage facilities, processing plants, technical maintenance. The sales of products remain another big problem: this risk results in losses despite the efforts of the landowners, therefore future state control shall be aimed at further expansion of the sales channels.

description: X-ray devices are far superior to optical ones for providing nanometre spatial and attosecond temporal resolutions. Such resolution is indispensable in biology, medicine, physics, material sciences, and their applications. A bright ultrafast coherent X-ray source is highly desirable, for example, for the diffractive imaging of individual large molecules, viruses, or cells. Here we demonstrate experimentally a new compact X-ray source involving high-order harmonics produced by a relativistic-irradiance femtosecond laser in a gas target. In our first implementation using a 9 Terawatt laser, coherent soft X-rays are emitted with a comb-like spectrum reaching the 'water window' range. The generation mechanism is robust being based on phenomena inherent in relativistic laser plasmas: self-focusing, nonlinear wave generation accompanied by electron density singularities, and collective radiation by a compact electric charge. The formation of singularities (electron density spikes) is described by the elegant mathematical catastrophe theory, which explains sudden changes in various complex systems, from physics to social sciences. The new X-ray source has advantageous scalings, as the maximum harmonic order is proportional to the cube of the laser amplitude enhanced by relativistic self-focusing in plasma. This allows straightforward extension of the coherent X-ray generation to the keV and tens of keV spectral regions. The implemented X-ray source is remarkably easily accessible: the requirements for the laser can be met in a university-scale laboratory, the gas jet is a replenishable debris-free target, and the harmonics emanate directly from the gas jet without additional devices. Our results open the way to a compact coherent ultrashort brilliant X-ray source with single shot and high-repetition rate capabilities, suitable for numerous applications and diagnostics in many research fields.

According to scientists data, nonsaline alkaline soils and alkaline soil takes up approximately 30% of the republic’s total cropland area. The territory belongs to sulfur-sodium saline accumulation type. When chemically meliorated by gypsum the soil on 0-40cm layer activates the resalinization process. With such treatment feeding crops yield was 14.4-20.2 t/ha with gypsum only; with green manure fertilizer at the background11,4-16,1 t/ha. Yield increased by 33-64 quintals per hectare, meaning being increased by 20,844,4%. By productivity means, vetch-oat mixes in gypsum treatment variant contained 0,66-0,79 feeding units, 94,15-123,11 digestible protein units and 16,7817,80MJ of gross energy per 1kg of the dry component. Control samples’ exchange energy was 8,13MJ, wherein gypsum treated sample was 9,00-9,53MJ. Improved soil water permeability and aeration facilitated the increase in root uptake of calcium, potassium, phosphorus, and microelements in gypsum treated saline soils. Altogether, such way of soil treatment is very likely having a positive impact on feeding crops yield in saline soils of Central Yakutia.

description: A new model for the finite one-dimensional harmonic oscillator is proposed based upon the algebra u(2)_α. This algebra is a deformation of the Lie algebra u(2) extended by a parity operator, with deformation parameter α. A class of irreducible unitary representations of u(2)_α is constructed. In the finite oscillator model, the (discrete) spectrum of the position operator is determined, and the position wave functions are shown to be dual Hahn polynomials. Plots of these discrete wave functions display interesting properties, similar to those of the parabose oscillator. We show indeed that in the limit, when the dimension of the representations goes to infinity, the discrete wave functions tend to the continuous wave functions of the parabose oscillator.

description: Numerical values of charged-particle thermonuclear reaction rates for nuclei in the A=14 to 40 region are tabulated. The results are obtained using a method, based on Monte Carlo techniques, that has been described in the preceding paper of this series (Paper I). We present a low rate, median rate and high rate which correspond to the 0.16, 0.50 and 0.84 quantiles, respectively, of the cumulative reaction rate distribution. The meaning of these quantities is in general different from the commonly reported, but statistically meaningless expressions, "lower limit", "nominal value" and "upper limit" of the total reaction rate. In addition, we approximate the Monte Carlo probability density function of the total reaction rate by a lognormal distribution and tabulate the lognormal parameters μ and σ at each temperature. We also provide a quantitative measure (Anderson-Darling test statistic) for the reliability of the lognormal approximation. The user can implement the approximate lognormal reaction rate probability density functions directly in a stellar model code for studies of stellar energy generation and nucleosynthesis. For each reaction, the Monte Carlo reaction rate probability density functions, together with their lognormal approximations, are displayed graphically for selected temperatures in order to provide a visual impression. Our new reaction rates are appropriate for bare nuclei in the laboratory. The nuclear physics input used to derive our reaction rates is presented in the subsequent paper of this series (Paper III). In the fourth paper of this series (Paper IV) we compare our new reaction rates to previous results.
