description: In order to understand properties of ultrathin copper nanowires, we have simulated several copper nanowires using classical molecular dynamic simulations. As the temperature increases, copper nanowires were transformed into structures of the lowest surface stresses and surface energy, circular cross-section with {111}-like surface. As thickness of copper nanowire increases, the breaking of nanowire and the structural transition hardly occurrs. From studies of angular correlation and radial distribution functions, it was shown that ultrathin {111} nanowires was more stable than that of {100} nanowires. The vibrational frequency of nanowires was different to that of bulk about 3 THz and above 8 THz. The structural properties of cylindrical multi-shell nanowires were greatly different from that of face centered cubic.

description: Microgravity conditions are required to study plant performance in space and are modelled on the Earth’s ground using 3D-clinorotation, under which growing plants are constantly rotated around two orthogonal axes [1]. We have applied the special ionic exchanger polyacrylonitrile fiber substrate Panion-110/320 to facilitate successful cultivation of Arabidopsis plants during the whole ontogenesis under 3D-clinorotation up to the formation of viable seeds. 3D-clinorotation caused a transient (≈ 20 h) delay in biomass growth, accompanied by a rise in total H2O2 content in 10–14 day old seedlings. Clinorotation also inhibited root elongation temporarily, stimulated excessive root curvature and directed root growth abnormally. Metabolite profiling of 10–14 day old seedlings showed the trend to decrease in content of the majority of metabolites under clinorotation except for malate.Pulse amplitude modulation (PAM) fluorometric analysis of photochemical activity in leaves of 3D-clinorotated seedlings was performed to understand the peculiar properties of plant cultivation in microgravity conditions. We have also studied cytoskeleton organization in vivoin 7 day old Arabidopsis seedlings usingGFP-fABD2 and Lifeact-Venus transgenic lines for microfilaments (MFs), and MAP4-GFP and TUA6-GFP lines for microtubules (MTs). Under vertical growth conditions, MTs laid oblique both in hypocotyl and in root elongation zone and did not change significantly under 3D-clinorotation. In actin cytoskeleton, axial MFs dominated both in root cortex and stele in elongation zone, followed by oblique MFs, and minor transversally oriented MFs. However, microgravity modelling lowered the fraction of axial MFs by 50% in root cortex but not in stele, the total number of MFs was lower as well, and the fraction of transversal MFs was higher, contributing to overall ‘randomized’ image of actin. Remarkably, first in a lifetime placement of seedlings from 3D-clinorotation to a vertical position stimulated fast actin ‘axialization’ within 30 min. Therefore, we suggest that the ‘default’ organization of actin is random in the absence of gravity vector, and MF axial orientation is stimulated by gravity.The study was supported by RFBR project No. 17-04-00862 to S.M.References:1.

description: Lorentz symmetry is an important concept in modern physics. Precision pulsar timing was used to put tight constraints on the coefficients for Lorentz violation in the pure-gravity sector of the Standard-Model Extension (SME). We extend the analysis to Lorentz-violating matter-gravity couplings, utilizing three small-eccentricity relativistic neutron star (NS) -- white dwarf (WD) binaries. We obtain compelling limits on various SME coefficients related to the neutron, the proton, and the electron. These results are complementary to limits obtained from lunar laser ranging and clock experiments.

description: The effects of the agricultural crisis have also been felt among business operators in small towns of North Dakota. Our recent survey of business operators provides a first-hand glimpse at how farm events affected nonfarm businesses, the management adjustments operators made, and their expectations for the next few years. Businesses that started up in the 1970's appear to have been hurt most by declining revenue and falling equity in the farm sector. Business operators were nonetheless cautiously optimistic about the future.
Fast and Accurate Computation of Vertical Modes

description: The vertical modes of linearized equations of motion are widely used by the oceanographic community in numerous theoretical and observational contexts. However, the standard approach for solving the generalized eigenvalue problem using second-order finite difference matrices produces $O(1)$ errors for all but the few lowest modes, and increasing resolution quickly becomes too slow as the computational complexity of eigenvalue algorithms increase as $O(n^3)$. Existing methods are therefore inadequate for computing a full spectrum of internal waves, such as needed for initializing a numerical model with a full internal wave spectrum. Here we show that rewriting the eigenvalue problem in stretched coordinates and projecting onto Chebyshev polynomials results in substantially more accurate modes than finite-differencing at a fraction of the computational cost. We also compute the surface quasigeostrophic modes using the same methods. All spectral and finite difference algorithms are made available in a suite of Matlab classes that have been validated against known analytical solutions in constant and exponential stratification.

description: By doping MgB_2 superconductor with SiC nano-particles, we have successfully introduced pinning sites directly into the crystal lattice of MgB_2 grains (intra-grain pinning). It became possible due to the combination of counter-balanced Si and C co-substitution for B, leading to a large number of intra-granular dislocations and the dispersed nano-size impurities induced by the substitution. The magnetic field dependence of the critical current density was significantly improved in a wide temperature range, whereas the transition temperature in the sample MgB_2(SiC)_x having x = 0.34, the highest doping level prepared, dropped only by 2.6 K.

description: We revisit charge density wave (CDW) behavior in the archetypal quasi-one-dimensional (quasi-1D) material NbSe$_3$ by high-resolution angle-resolved photoemission spectroscopy measurements utilizing a microfocused laser with a photon energy of 6.3 eV. We present a detailed view of the electronic structure of this complex multiband system and unambiguously resolve CDW gaps at the Fermi level ($E_F$). By employing a tight-binding model, we argue that these gaps are the result of interband coupling between electronic states that reside predominantly on distinct 1D chains within the material. Two such localized states are found to couple to an electronic state that extends across multiple 1D chains, highlighting the importance of a higher-dimensional interaction in stabilizing the CDW ordering in this material. In addition, the temperature evolution of intrachain gaps caused by the CDW periodicities far below $E_F$ deviate from the behavior expected for a Peierls-type mechanism driven by nesting; the upper and lower bands of the renormalized CDW dispersions maintain a fixed peak-to-peak distance while the gaps are gradually removed at higher temperatures. This points toward a gradual loss of long-range phase coherence as the dominant effect in reducing the CDW order parameter, which may correspond to the loss of coherence between the coupled chains. Furthermore, one of the gaps is observed above the bulk and surface CDW transition temperatures, implying the persistence of short-range incoherent CDW order. The influence of such higher-dimensional interactions likely plays an important role in a range of low-dimensional systems.

Investigation of optimization methods used for reconfiguration of the naval electric ship power system

Constrained simulated annealing

description: The future generation of United States naval electric ships will be completely powered by electricity and will have the ability to reconfigure the power system to adapt to the dynamic needs of the ship. This thesis explores four different numerical methods used to find the optimal switch state for the system. Each optimization routine was applied to three different case studies, each with different problem constraints. The methods were evaluated based on computational speed, accuracy in finding the best solution, and amount of setup time needed The method used depends heavily on the degree that the problem is constrained and the solution requirements. The direct search method is completely accurate and requires little setup time, but its slow speed motivates the search for quicker methods. The genetic algorithm performed quickly and found an accurate solution, but it is subject to multiple parameters whose roles are difficult to quantify. The binary integer procedure works very quickly and is easy to set up, but its solution accuracy is limited. The constrained simulated annealing method works well across a variety of problems. Although it is affected by many parameters, their role in shaping the method’s effectiveness is easier to empirically and conceptually understand compared to the genetic algorithm. If the percentage error must be less than two percent, the genetic algorithm is typically the fastest method. Otherwise, constrained simulated annealing is recommended due to its computational speed and setup time

The collection of Schwarzschild and Reissner-Nordström wormholes are separately considered to represent the foam. The Casimir energy shows that the Reissner-Nordström wormholes cannot be used to represent the foam.

INTEGRATED PHOTONICS WAVEFRONT SENSOR (IP WFS)

description: In this work, a novel kind of wavefront sensor (WFS) for adaptive optics in solar physics based on integrated photonics is proposed. Shack-Hartmann and plenoptic sensors are limited to pupil sampling of approximately 8 cm because they need a solar granulation image with a minimum contrast to be able to compute displacements. To overcome this limitation and effectively use existing deformable mirrors with thousands of actuators, a novel WFS is proposed, which will be able to obtain wavefront phase differences of the beam with higher pupil sampling. The proposed WFS can increase the resolution and speed with respect to the other sensors as the incoming wavefront is obtained by passing the wavefront through optical fibres to the Integrated Photonics - Wavefront Sensor (IP-WFS) and directly measuring the phase differences without the generation of images. In the same way as Shack-Hartmann and plenoptic sensors, the proposed IP-WFS delivers data about the phase differences on the incoming wavefront to subsequently use this information to calculate the deformable mirror actuation. Consequently, the integration of the proposed IP-WFS in the current systems of adaptive optics can be performed without having to make drastic modifications to the existing instruments.

description: The inflaton potential in four-dimensional theory is rather arbitrary, and fine-tuning is required generically. By contrast, inflation in the brane world scenario has the interesting feature that the inflaton potential is motivated from higher dimensional gravity, or more generally, from bulk modes or string theory. We emphasize this feature with examples. We also consider the impact on the spectrum of density perturbation from a velocity-dependent potential between branes in the brane inflationary scenario. It is likely that such a potential can have an observable effect on the ratio of tensor to scalar perturbations.

As numerical examples quantum spin systems are studied. Our initial aim was to identify pathological examples or circumstances, such as strong frustration or unusual densities of states, where these methods could fail. Instead we failed with the attempt. All investigated systems allow such approximations, only at temperatures of the order of the lowest energy gap the convergence is somewhat slower in the number of random vectors over which observables are averaged.

description: In the framework of a Fermi liquid theory it is considered the possibility of ferromagnetic and antiferromagnetic phase transitions in symmetric nuclear matter with Skyrme effective interaction. The zero temperature dependence of ferromagnetic and antiferromagnetic spin polarization parameters as functions of density is found for SkM$^*$, SGII effective forces. It is shown that in the density domain, where both type of solutions of self--consistent equations exist, ferromagnetic spin state is more preferable than antiferromagnetic one.

description: In this paper we deal with the notion of the effective impedance of AC networks consisting of resistances, coils and capacitors. Mathematically such a network is a locally finite graph whose edges are endowed with complex-valued weights depending on a complex parameter $λ$ (by the physical meaning, $λ=iω$, where $ω$ is the frequency of the AC). For finite networks, we prove some estimates of the effective impedance. Using these estimates, we show that, for infinite networks, the sequence of impedances of finite graph approximations converges in certain domains in $\mathbb{C}$ to a holomorphic function of $λ$, which allows us to define the effective impedance of the infinite network.

The recently observed huge enhancement $T_1^{-1}({\bf r})$ below $T_c$ at a core site in Tl$_2$Ba$_2$CuO$_6$ is explained.

description: Nowadays, in globalization industries are adopting new techniques and tools to produce goods for sustainability. However, manufacturing industries are facing challenges to minimize operations costs, market inconsistency, competition, and variance demands. Lean practice helps sustainability of the industries by doing more with less resources through elimination of non-value-added activities to maintain effectiveness and profitability. A study uses the method of survey to identify factors for effective implementation of the lean manufacturing. Two industries producing plastics, metals, textiles, woods, biscuits, and bread products were selected for the study. The results revealed that manufacturing planning and control, new product development, process and equipment, concurrent engineering, workforce management, customer relationship, and supplier relationship are positive factors for the adoption of lean practice in Vietnam. However, a lean model indicates that concurrent engineering has the highest correlation to lean practice whereas new product development has the lowest significance. The new product development is not common because most industries have a lack of innovation, limited technology, less desire of customers on changes of product features, dearth of research and development culture, lack of desire from top management, inadequate resources, and a fear of failure for new products. It was advised that effective application of lean factors enable companies to map risk of non-value-added activities and improve business value.
A multidisciplinary approach to studying language attitudes and language use in the Ottawa-Gatineau region

Language behavior

description: This dissertation focuses on the language behavior of individuals from the Ottawa– Gatineau metropolitan region (OGR) and the ways in which it correlates with their language attitudes as expressed in social media and in person. Although attitudes are believed to be intrinsically related to behavior, there is a lack of consensus among social psychologists regarding the nature of this relationship. Furthermore, there is a paucity of work exploring the link between language attitudes (LA) and language behavior. I intend to address this gap through my dissertation. The OGR is a fertile ground for such a study. It is a largely stable bilingual region where a total of 48.5% of the population speaks English and 30.3% speaks French as their mother tongue (Statistics Canada, 2016). However, the region is not a homogenous linguistic community. It is linguistically divided by the Québec-Ontario provincial border with the largely francophone Gatineau on the Québec side and the mainly anglophone Ottawa on the Ontario side of the border. The two cities are also different in terms of language policies and language planning measures adopted by their respective municipal and provincial governments. In this study, I established language use patterns through ethnographic observations in local cafés, farmer’s markets and grocery stores and through people’s use of French and English on Twitter. Language attitudes were assessed through a language attitude questionnaire (Kircher, 2009) distributed among people in different public spaces in the OGR and through a study of tweets from individuals in the region. The analysis reveals important differences in language attitudes and language use among francophones and anglophones. We also noticed that the two official languages do not enjoy the same status and that attitudes towards Québec/Canadian French (QF/CF) are more negative than attitudes towards European French (EF) or the French language in general. Finally, we discovered that language attitudes and language use had an important influence on each other, but this relationship was dependent on other factors as well.
The Schwarzschild solution in a Kaluza-Klein theory with two times

description: A new spherically-symmetric solution is determined in a noncompactified Kaluza-Klein theory in which a time character is ascribed to the fifth coordinate. This solution contains two independent parameters which are related with mass and electric charge. The solution exhibits a Schwarzschild radius and represents a generalization of the Schwarzschild solution in four dimensions. The parameter of the solution connected with the electric charge depends on the derivative of the fifth (second time) coordinate with respect to the ordinary time coordinate. It is shown that the perihelic motion in four-dimensional relativity has a counterpart in five dimensions in the perinucleic motion of a negatively-charged particle. If the quantization conditions of the older quantum theory are applied to that motion, an analogue of the fine-structure formula of atomic spectra is obtained.

description: Look for another round of farm, consolidation, older farmers, and higher farm income by the turn of the century. The number of farmers by then may be 20 percent below the 1982 figure. Abetting these changes are the precarious financial position of many who began farming in the 1970's and fewer farm children to take over from parents. These trends may portend slower productivity growth, more leasing of farmland, and a changing marketplace for businesses and institutions serving the farm sector.

description: Quantum Belinski-Khalatnikov-Lifshitz scenario presents an unitary evolution of the system. However, the affine coherent states quantization applied to the quantization of the underlying classical scenario depends on the choice of the group parametrization. Using two simplest parameterizations of the affine group, we show that qualitative features of our quantum system do not depend on the choice. It means that the quantum bounce replacing singular classical scenario is expected to be a generic feature of considered system. This paper complements our recent article [1].

description: Studies on small and medium-sized towns have begun to focus on the role of agency in shaping industrial transformation outcomes. Local agency plays a key role in determining the direction of transformation of industrial towns, yet it is unclear how they shape transformation paths in the context of smallness and multiscalarity. By comparing six industrial towns in Switzerland and Slovenia, we explore how local actors bridge scales, particularly through the lens of institutional work. This study contributes to a nuanced understanding of smallness as both an opportunity and a limitation for local change agents.

Each period, the investor selectively discloses his information to influence the manager's capital investment decision. While the manager knows that she can learn from the investor's disclosures, she also knows that the investor is trying to manipulate her; in equilibrium, the investor's incentives to mislead the manager constrain the credibility of his disclosures, leading to a mutually-deleterious loss of information. I compare the set of cheap talk equilibria with the Bayesian persuasion equilibrium. My model has implications for short-termism, management guidance, and investor credibility over the business cycle.

description: This paper examines off-farm labor supply effects of farm mechanization. The conceptual framework in the paper suggests positive effect of farm mechanization on farm operator’s off-farm labor supply. The paper uses adoption of tractor as proxy measure of farm mechanization and utilizes a nationally representative household survey dataset from Bangladesh. Using Probit and Tobit models, the paper finds support for the proposition that farm mechanization boosts farm operator’s off-farm labor supply.

Competition

description: This dissertation provides an overview of the interaction between banks and shadow banks in the two markets: the warehouse lending market, in which banks supply funding to shadow banks, and in the mortgage origination market, in which banks and shadow banks compete with each other. It studies how their interaction in one market affects their interaction in the other market, the equilibrium feedback between the two markets, and the implications for policy pass-though. I collect shadow bank call reports through FOIA requests and document that most of shadow banks’ warehouse funding is obtained from the banks that compete with them in the mortgage market. I provide evidence that banks trade off information advantage in warehouse lending against the loss in profits from increased mortgage market competition: (i) warehouse lending is clustered between competitors in local mortgage markets, especially in regions where public information of local housing value is less reliable; (ii) shadow banks cannot easily substitute to alternative funding sources if their relationship banks exogenously reduce warehouse lending; and (iii) a bank lends less to shadow banks in regions where it has greater market share in mortgage origination. To study the net effect on mortgage market competition in equilibrium, I calibrate a quantitative model that links warehouse lending and mortgage market competition. Warehouse lending market power is substantial. Banks charge 30% extra markups to the competing shadow banks relative to non-competitors. In the counterfactual, a faster GSE loan purchase program, which changes the warehouse lending market structure, would increase mortgage market competition, improving consumer welfare by $3.5 billion.

description: We focus on understanding the influence of the two-component coupling in ferronematics, a colloidal suspension of magnetic nanoparticles in nematic liquid crystals. Using coarse-grained Landau-de Gennes free energies, we study the ordering dynamics of this complex fluid and present a range of analytical and numerical results. Our main observations are: (i) slaved coarsening for quench temperatures $T$ intermediate to the critical temperatures of the uncoupled components, (ii) slower growth similar to the Lifshitz-Slyozov law ($L \sim t^{1/3}$) for symmetric magneto-nematic coupling, (iii) sub-domain morphologies dominated by interfacial defects for asymmetric coupling strengths. These novel results will serve to guide future experiments on this technologically important system.

description: USDA conducts mandatory census survey every 5 year. According to the report the total amount of farms drops to 1,717,898 in 2012, which is 23.34% less then that in 1982. The number of farm exits varies from 906,100 to 652,597 during the 30 years. What are the factors influencing farm exit rates will be studied with logistic regression.
Exact Hurst exponent and crossover behavior in a limit order market model

description: An exclusion particle model is considered as a highly simplified model of a limit order market. Its price behavior reproduces the well known crossover from over-diffusion (Hurst exponent H>1/2) to diffusion (H=1/2) when the time horizon is increased, provided that orders are allowed to be canceled. For early times a mapping to the totally asymmetric exclusion process yields the exact result H=2/3 which is in good agreement with empirical data. The underlying universality class of the exclusion process suggests some robustness of the exponent with respect to changes in the trading rules. In the crossover regime the Hurst plot has a scaling property where the bulk deposition/cancellation rate is the critical parameter. Analytical results are fully supported by numerical simulations.

description: Introduction: There are limited data on optimal dosing of antibiotics in different age groups for neonates and children. Clinicians usually consult pediatric formularies or online databases for dose selection, but these have variable recommendations, are usually based on expert opinion and are not graded based on the existing pharmacokinetic-pharmacodynamic (PKPD) studies. We describe here a potential new tool that could be used to grade the strength of evidence emanating from PKPD studies. Areas covered: A scoring system was developed (GAPPS tool) to quantify the strength of each PK assessment and rate the studies quality in already published articles. GAPPS was evaluated by applying it to pediatric PKPD studies of antibiotics from the 2019 Essential Medicines List for children (EMLC), identified through a search of PubMed. Expert opinion: Evidence for most antibiotic dose selection decisions was generally weak, coming from individual PK studies and lacked PKPD modeling and simulations. However, the quality of evidence appears to have improved over the last two decades. Incorporating a formal grading system, such as GAPPS, into formulary development will provide a transparent tool to support decision-making in clinical practice and guideline development, and guide PKPD authors on study designs most likely to influence guidelines.

description: We develop a new parametric bootstrap-based statistical test for presence of futures price and options-based implied volatility biases. The new test is applicable to data with overlapping prediction horizons. Information on anticipated volatility embedded in options prices is explicitly used when testing for futures price biases. Our method is well adapted to analysis of fast changing commodity markets as it does not rely on asymptotic theory and does not require a time series spanning several decades. We apply the new test to investigate if futures and options biases can explain very low loss ratios exhibited by USDA’s Livestock Gross Margin for Dairy Cattle insurance program.
Interaction and coalescence of large bubbles rising in a thin gap

description: We present accurate measurements of the relative motion and deformation of two large bubbles released consecutively in a quiescent liquid confined in a thin-gap cell. Though the second bubble injected is smaller, we observed that in all cases it accelerates and catches up with the leading bubble. This acceleration is related to the wake of the leading bubble which also induces significant changes in the width and curvature of the trailing bubble. On the contrary, the velocity of the leading bubble is unaltered during the whole interaction and coalescence process. Shape adaptation of the two bubbles is observed just prior to coalescence. After pinch-off, the liquid film is drained at a constant velocity.

description: The low-temperature specific heat C(T,H) of a new superconductor MgCNi3 has been measured in detail. (C/gammasub_nTc=1.97 is estimated from the anomaly at Tc. At low temperatures, the electronic contribution in the superconducting state follows Ces/gammasub_nTc=7.96exp(-1.46Tc/T). The magnetic field dependence of gamma(H) is found to be linear with respect to H. Tc estimated from the McMillan formula agrees well with the observed value. All the specific heat data appear to be consistent with each other within the moderate-coupling BCS context. It is amazing that such a superconductor unstable to ferromagnetism behaves so conventionally. The Debye temperature Thetasub_D=287 K and the normal state gammasub_n=33.6 mJ/mol K2 are determined for the present sample. Discussions on the existence of a small magnetic coupling and unconventional order parameter are also presented.
