description: The Suzaku AGN Spin Survey is designed to determine the supermassive black hole spin in six nearby active galactic nuclei (AGN) via deep Suzaku stares, thereby giving us our first glimpse of the local black hole spin distribution. Here, we present an analysis of the first target to be studied under the auspices of this Key Project, the Seyfert galaxy NGC 3783. Despite complexity in the spectrum arising from a multi-component warm absorber, we detect and study relativistic reflection from the inner accretion disk. Assuming that the X-ray reflection is from the surface of a flat disk around a Kerr black hole, and that no X-ray reflection occurs within the general relativistic radius of marginal stability, we determine a lower limit on the black hole spin of a > 0.88 (99% confidence). We examine the robustness of this result to the assumption of the analysis, and present a brief discussion of spin-related selection biases that might affect flux-limited samples of AGN.

Testing, advancing, and applying an isotope mass balance model to investigate nitrogen uptake and assimilation in poplar and willow
Creators: name: Hu, Yi
Publisher: name: University of British Columbia
Year: 2022

description: Poplars and willows are widely distributed in temperate ecosystems and are important woody crops, but their growth depends on adequate (and often replete) supplies of water and nitrogen. Nitrogen isotope discrimination (∆¹⁵N) have utility as an indicator of nitrogen-use in plants, and an isotope mass balance (IMB) model has been proposed to estimate the fluxes across root plasma membranes (E/I), the proportion of inorganic nitrogen assimilated in roots (Proot) and translocation of inorganic nitrogen to shoots (Ti/Tt) under steady-state conditions. Good correspondence between model-estimated E/I and compartmental analysis of tracer efflux has been demonstrated. In this thesis, the IMB model was further validated and then, after adjusting the ∆¹⁵N value of nitrate reductase (∆enzyme), used to explore intraspecific variation in nitrogen-use in black cottonwood (Populus trichocarpa Torr. & Gray) and heart-leaved willow (Salix eriocephala Michx.). To test the IMB model, I measured concentrations and δ¹⁵N of inorganic and organic nitrogen in xylem sap extracted from stems of black cottonwood provisioned hydroponically with nitrate. Direct determinations of Ti/Tt and Proot compared very favorably with IMB model-derived estimates. The difference in δ¹⁵N between organic-N and NO3̄ -N fractions in xylem sap (24.9‰) suggests a ∆enzyme of 25.1‰, which is higher than previously assumed by the IMB model, but close to recent estimates that average ~22‰. There was significant variation in nitrogen-use related traits in both poplar and willow. In heart-leaved willow, variation in δ¹⁵N, δ¹³C and C/N ratios indicated differences in nitrogen uptake and assimilation, WUE, and NUE. Clinal variation in δ¹⁵N was found in field and hydroponic experiments, possibly related to water availability. The absence of a trade-off between E/I, WUE, and NUE in willow suggests that additive variation in these traits can be captured without compromise. Variation in growth, R:S ratio, ∆¹⁵N, and C/N ratio was also found in black cottonwood, but biogeoclimatic correlations were not strong. The GWAS study using root and leaf ∆¹⁵N and other traits did not find significant genes related to nitrate transport or assimilation. There was one for root ∆¹⁵N and several for R:S ratio, which was in turn correlated with whole-plant ∆¹⁵N and E/I.

Stimulated Supersymmetry Breaking

description: We show that small soft terms can create a supersymmetry breaking minimum along a pseudo-flat direction of a hidden sector which would otherwise be incapable of spontaneous supersymmetry breaking. As this minimum lies along a pseudo-flat direction, with non-zero F- or D-terms, the resultant supersymmetry breaking in the hidden sector can be orders of magnitude greater than the soft terms which created the minimum. This opens new avenues for building models of gauge mediation, may have consequences for the cosmology of hidden sectors, and strengthens the case for multiple supersymmetry breaking sectors.

Search for pair production of first or second generation leptoquarks in proton-proton collisions at sqrt(s)=7 TeV using the ATLAS detector at the LHC
Creators: name: The ATLAS Collaboration
Publisher: name: arXiv
Year: 2011
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: This paper describes searches for the pair production of first or second generation scalar leptoquarks using 35/pb of proton-proton collision data recorded by the ATLAS detector at sqrt(s)=7 TeV. Leptoquarks are seached in events with two oppositely charged muons or electrons and at least two jets, and in events with one muon or electron, missing transverse momentum and at least two jets. After event selection, the observed yields are consistent with the predicted backgrounds. Leptoquark production is excluded at the 95% CL for masses mLQ<376 (319) GeV and mLQ<422 (362) GeV for first and second generation scalar leptoquarks, respectively, when assuming the branching fraction of a leptoquark to a charged lepton is equal to 1.0 (0.5).

description: For an Indigenous population, there is a need for an inclusive educational space from the language and culture srevitalisation perspective. This is especially important during the early years when the basics of the language are formed alongside cultural knowledge. This paper takes a closer look at a South Sámi preschool language learning environment through the lenses of teachers. The South Sámi (South Saami) is the southernmost Sámi population, frequently described as a minority within the minority. The estimation for South Sámi speakers in Norway is around 300, making the language severely endangered This paper aims to take a closer look at how early childhood education teachers describe the South Sámi language learning space in their preschool environment. For this study, in total, three preschool teachers from a South Sámi preschool were interviewed. This textual data were analysed with content analysis. According to the results, the early childhood education in South Sámi context was seen as an important inclusive language and culture srevitalising space with a clear societal responsibility.

description: Two different oscillation modes in microdischarge with parallel-plate geometry has been observed: relaxation oscillations with frequency range between 1.23 and 2.1 kHz and free-running oscillations with 7 kHz frequency. The oscillation modes are induced by increasing power supply voltage or discharge current. For a given power supply voltage, there is a spontaneous transition from one to other oscillation mode and vice versa. Before the transition from relaxation to free-running oscillations, the spontaneous increase of oscillation frequency of relaxation oscillations form 1.3 kHz to 2.1 kHz is measured. Fourier Transform Spectra of relaxation oscillations reveal chaotic behaviour of microdischarge. Volt-Ampere characteristics associated with relaxation oscillations describes periodical transition between low current, diffuse discharge and normal glow. However, free-running oscillations appear in subnormal glow only.

These include alignments of the largest modes of CMB anisotropy with each other and with geometry and direction of motion of the Solar System, and the unusually low power at these largest scales. We discuss these findings in relation to expectation from standard inflationary cosmology, their statistical significance, the tools to study them, and the various attempts to explain them.

Assessment of source water microbial quality using Bayesian belief networks and data balancing algorithms
Creators: name: Aliashrafi Zagi, Atefeh
Publisher: name: University of British Columbia
Year: 2022

description: Cryptosporidium and E. coli are recognized as critical pathogens in source water with mortality risk. In order to protect public health from waterborne risks, monitoring of Cryptosporidium and E. coli in drinking water sources is essential. However, direct measurement of these pathogens is expensive and labor-intensive, resulting in limited information and time-delays for risk-based management of water systems. While these challenges slow down the real-time monitoring of pathogens’ levels in ambient waters, AI-based techniques offer a fast and effective alternative for direct measurements. Bayesian Belief Networks (BBNs) is one of these data-driven methods gaining traction in modelling environmental systems and capturing their uncertainties. BBNs can assist the decision-makers by visualizing the interaction of variables in the complex systems. In this thesis, BBNs have been used to estimate Cryptosporidium and E. coli levels to provide a real-time assessment of the microbial quality of source water and fill the time gap required for direct measurement. However, available Cryptosporidium data are rare and unbalanced, mainly indicating absence or non-detectable levels of Cryptosporidium. To overcome this challenge, two data balancing algorithms, Adaptive Synthesized Sampling (ADASYN) and Synthetic Over Sampling Technique (SMOTE) have been utilized. The objective was to eliminate unbalanced features of the dataset and train the model in a way that can predict both presence and absence of Cryptosporidium based on unbalanced and real measurements. In current work, the BBN model has been used for Cryptosporidium prediction and trained for the first time with a balanced dataset generated through ADASYN and SMOTE algorithms. The application of balancing algorithms increased the prediction accuracy to more than 60%, compared with models developed by unbalanced datasets. Furthermore, the sensitivity of pathogen’s level to different water quality and weather parameters was also investigated with the aim of improving the information regarding factors influencing source waters quality. Although precipitation and temperature indicated a significant impact on target parameters, the scale of the impact was very site-specific. The observation indicated that besides weather and water quality characteristics, different characteristics of each monitoring site seem to affect the level of Cryptosporidium and E. coli in studied water sources.

description: The latest CDF anomaly, the excess of dijet events in the invariant-mass window 120-160 GeV in associated production with a $W$ boson, can be explained by a baryonic $Z'$ model in which the $Z'$ boson has negligible couplings to leptons. Although this $Z'$ model is hardly subject to the Drell-Yan constraint from Tevatron, it is constrained by the dijet data from UA2 ($\sqrt{s} = 630$ GeV), and the precision measurements at LEP through the mixing with the SM $Z$ boson. We show that under these constraints this model can still explain the excess in the M_{jj} \sim 120 - 160 GeV window, as well as the claimed cross section $σ(W Z') \sim 4$ pb. Implications at the Tevatron would be the associated production of $γZ',\; Z Z'$, and $Z'Z'$ with the $Z' \to jj$. We show that with tightened jet cuts and improved systematic uncertainties both $γZ' \to γjj$ and $Z Z' \to \ell^+ \ell^- j j$ channels could be useful to probe this model at the Tevatron.

description: We propose a realistic generalization of the Maki-Thompson rumour model by assuming that each spreader ceases to propagate the rumour right after being involved in a random number of stifling experiences. We consider the process with a general initial configuration and establish the asymptotic behaviour (and its fluctuation) of the ultimate proportion of ignorants as the population size grows to $\infty$. Our approach leads to explicit formulas so that the limiting proportion of ignorants and its variance can be computed.

description: A major challenge of spintronics is in generating, controlling and detecting spin-polarized current. Manipulation of spin-polarized current, in particular, is difficult. We demonstrate here, based on calculated transport properties of graphene nanoribbons, that nearly +-100% spin-polarized current can be generated in zigzag graphene nanoribbons (ZGNRs) and tuned by a source-drain voltage in the bipolar spin diode, in addition to magnetic configurations of the electrodes. This unusual transport property is attributed to the intrinsic transmission selection rule of the spin subbands near the Fermi level in ZGNRs. The simultaneous control of spin current by the bias voltage and the magnetic configurations of the electrodes provides an opportunity to implement a whole range of spintronics devices. We propose theoretical designs for a complete set of basic spintronic devices, including bipolar spin diode, transistor and logic gates, based on ZGNRs.

description: Positive-parity spin-1/2 excitations of the nucleon are explored in lattice QCD. The variational method is used in this investigation and several correlation matrices are employed. As our focus is on the utility and methodology of the variational approach, we work in the quenched approximation to QCD. Various sweeps of Gaussian fermion-field smearing is applied at the source and at the sink of $χ_{1}\barχ_{1}$ and $χ_{1}χ_{2}$ correlation functions to obtain a large basis of operators. Using several different approaches for constructing basis interpolators, we demonstrate how improving the basis can split what otherwise might be interpreted as a single state into multiple eigenstates. Consistency of the extracted excited energy states are explored over various dimensions of the correlation matrices. The use of large correlation matrices is emphasized for the reliable extraction of the excited eigenstates of QCD.

description: The axial light distributions in parallel-plate dc microdischarges in argon show similar behavior to large scale discharges. Between the low-current Townsend mode and the high current glow mode exists a large region of currents where different oscillations appear and the dynamic Volt-Ampere characteristic shows hysteresis behavior. During the oscillations the maximum peak intensity moves closer to the cathode, which is characteristic for the abnormal glow regime even though the average current is considerably smaller.

description: We study a known filtration of the second cohomology of a finite dimensional nilpotent Lie algebra $\mathfrak{g}$ with coefficients in a finite dimensional nilpotent $\mathfrak{g}$-module $M$, that is based upon a refinement of the correspondence between $\mathrm{H}^2(\mathfrak{g},M)$ and equivalence classes of abelian extensions of $\mathfrak{g}$ by $M$. We give a different characterization of this filtration and as a corollary, we obtain an expression for the second Betti number of $\mathfrak{g}$. Using this expression, we find bounds for the second Betti number and derive a cohomological criterium for the existence of certain central extensions of $\mathfrak{g}$.

description: I present a concise review of the major issues and challenges in particle physics at the start of the LHC era. After a brief overview of the Standard Model and of QCD, I will focus on the electroweak symmetry breaking problem which plays a central role in particle physics today. The Higgs sector of the minimal Standard Model is so far just a mere conjecture that needs to be verified or discarded by the LHC. Probably the reality is more complicated. I will summarize the motivation for new physics that should accompany or even replace the Higgs discovery and a number of its possible forms that could be revealed by the LHC.

title: Hull vibration analysis of a small multipurpose fishing vessel from Newfoundland and Labrador
Creators: name: Auf, Mohamed
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Regarded as one of the most dangerous industries for workers, commercial fishing is a high-risk industry that provides a living for millions around the world. It is imperative for designers to analyze and obtain practical solutions for the reduction of these unnecessary hazards. The need to quantify and analyze the risk areas onboard fishing vessels has been pressed by authorities worldwide from the increasing number of injuries and fatalities in this industry. Fishing vessels are mainly known for their high levels of vibrations due to their layout and relatively small size. Vibration mitigation on fishing vessels impacts both vessel equipment and onboard crew. Benefits of reduction include protection of sensitive ship equipment and hydro-acoustic apparatus, low noise emitted to the water so as not to scare fish schools, and increased safety of the onboard crew. Fish harvesters working in these vessels are in constant prolonged exposure causing a decrease in comfort levels leading to an unsafe work environment. The approach of this study is to effectively capture the dynamics of a case study fishing vessel in terms of vibrations, providing a practical methodology for designers to implement.

A unique Fock quantization for fields in non-stationary spacetimes

description: In curved spacetimes, the lack of criteria for the construction of a unique quantization is a fundamental problem undermining the significance of the predictions of quantum field theory. Inequivalent quantizations lead to different physics. Recently, however, some uniqueness results have been obtained for fields in non-stationary settings. In particular, for vacua that are invariant under the background symmetries, a unitary implementation of the classical evolution suffices to pick up a unique Fock quantization in the case of Klein-Gordon fields with time-dependent mass, propagating in a static spacetime whose spatial sections are three-spheres. In fact, the field equation can be reinterpreted as describing the propagation in a Friedmann-Robertson-Walker spacetime after a suitable scaling of the field by a function of time. For this class of fields, we prove here an even stronger result about the Fock quantization: the uniqueness persists when one allows for linear time-dependent transformations of the field in order to account for a scaling by background functions. In total, paying attention to the dynamics, there exists a preferred choice of quantum field, and only one $SO(4)$-invariant Fock representation for it that respects the standard probabilistic interpretation along the evolution. The result has relevant implications e.g. in cosmology.

Superstrings in AdS(2)xS(2)xT(6)

description: We consider the type IIB Green-Schwarz superstring theory on AdS(2)xS(2)xT(6) supported by homogeneous Ramond-Ramond 5-form flux and its type IIA T-duals. One motivation is to understand the solution of this theory based on integrability. This background is a limit of a 1/4 supersymmetric supergravity solution describing four intersecting D3-branes and represents a consistent embedding of AdS(2)xS(2) into critical superstring theory. Its AdS(2)xS(2) part with corresponding fermions can be described by a classically integrable PSU(1,1|2)/SO(1,1)xU(1) supercoset sigma-model. We point out that since the RR 5-form field has non-zero components along the 6-torus directions one cannot, in general, factorize the 10d superstring theory into the supercoset part plus 6 bosons and 6 additional massless fermions. Still, we demonstrate that the full superstring model (i) is classically integrable, at least to quadratic order in fermions, and (ii) admits a consistent classical truncation to the supercoset part. Following the analogy with other integrable backgrounds and starting with the finite-gap equations of the PSU(1,1|2)/SO(1,1)xU(1) supercoset we propose a set of asymptotic Bethe ansatz equations for a subset of the quantum string states.

description: Statistics and thermally activated dynamics of crack nucleation and propagation in a two-dimensional heterogeneous material containing quenched randomly distributed defects are studied theoretically. Using the generalized Griffith criterion we derive the equation of motion for the crack tip position accounting for dissipation, thermal noise and the random forces arising from the defects. We find that aggregations of defects generating long-range interaction forces (e.g., clouds of dislocations) lead to anomalously slow creep of the crack tip or even to its complete arrest. We demonstrate that heterogeneous materials with frozen defects contain a large number of arrested microcracks and that their fracture toughness is enhanced to the experimentally accessible time scales.

description: The energy-dependence of charged particle mean multiplicity and pseudorapidity density at midrapidity measured in nucleus-nucleus and (anti)proton-proton collisions are studied in the entire available energy range. The study is performed using a model, which considers the multiparticle production process according to the dissipating energy of the participants and their types, namely a combination of the constituent quark picture together with Landau relativistic hydrodynamics. The model reveals interrelations between the variables under study measured in nucleus-nucleus and nucleon-nucleon collisions. Measurements in nuclear reactions are shown to be well reproduced by the measurements in (anti)proton-proton interactions common and the corresponding fits are presented. Different observations in other types of collisions are discussed in the framework of the proposed model. Predictions are made for measurements at the forthcoming LHC energies.

description: The thin films, methods for measuring the properties of thin films, development of a device based on the STM-32 microcontroller for removing volt - ampere characteristics, electrical resistivity of thin films thin films with certain characteristics. The literature on various semiconductor structures (films) was analyzed. Various contact and contactless methods for measuring film parameters are considered, from which the contact-dual-probe method was chosen. Next, a circuit device based on an STM-32 microcontroller was developed that is capable of measuring current-voltage characteristics and specific electrical conductivity of samples.

description: The ${\cal F}$-lipped $SU(5)\times U(1)_X$ Grand Unified Theory (GUT) supplemented by TeV-scale vector-like particles from ${\cal F}$-theory, together dubbed ${\cal F}$-SU(5), offers a natural multi-phase unification process which suggests an elegant implementation of the No-Scale Supergravity boundary conditions at the unification scale $M_{\cal F} \simeq 7 \times 10^{17}$ GeV. Enforcing the No-Scale boundary conditions, including $B_μ(M_{\cal F})=0$ on the Higgs bilinear soft term, with the precision 7-year WMAP value on the dark matter relic density isolates a highly constrained "golden point" located near $M_{1/2} = 455$ GeV and $\tan β= 15$ in the $\tanβ-M_{1/2}$ plane, which simultaneously satisfies all known experiments, and moreover corresponds to an imminently observable proton decay rate. Because the universal gaugino mass is actually determined from established low energy data via Renormalization Group Equation (RGE) running, there are no surviving arbitrary scale parameters in the present model.
