description: We study the inclusive production of bottom-flavored hadrons from semileptonic decays of polarized top quarks at next-to-leading order in QCD using fragmentation functions recently determined from a global fit to $e^+e^-$ data. We provide the relevant differential decay widths at parton level in analytic form. These results fill an important gap in the theoretical interpretation of recent measurements of the top-quark polarization and the $t\bar{t}$ spin correlations using dilepton final states in proton-proton collisions at the CERN Large Hadron Collider. As an illustration, we study the distributions in the scaled bottom-hadron energy of the polarized-top-quark decay widths for different $W$-boson helicities.

description: It can be said that overfishing is the problem of ""too many boats chasing too few fish"". One can then question how fishing boats get developed in the first place, and what influences people to invest in boats. This research aims to approach this question of boat development, from the perspective of boatowners, in the context of Vietnamese tuna longline fishing industry. It aims to better understand tuna fishers' decision to acquire their first fishing boat, to reinvest in fishing boats, and the elements of resource sustainability that the fishers consider. This research employed a constructivist grounded theory method using qualitative data generated from interviews, observation and collected documents. In-depth face-to-face interviews were carried out with 28 tuna-fishing boat-owners and 44 other participants closely involved in the tuna fishing industry. Fieldwork was conducted mainly in three tuna-fishing provinces in Vietnam (Binh Dinh, Phu Yen, Khanh Hoa) during 2010-2012. Data analysis was conducted through two stages of coding, generating themes from the data and reporting propositions. The study finds that the decision of fishers to acquire their first fishing boat is, primarily, a commitment to work long-term as a fisher. Notably, fishers seem to self-select themselves into the occupation of fishing before they acquire their first boat; career identity is an important source of motivation for acquiring a boat. Aside from that fishers are also motivated by financial rewards and job satisfaction of fishing. The study examines two types of fishers' reinvestment activities: expanding their own boats, and acquiring extra boats. In both types fishers' reinvestments in boats are aimed at bringing about larger profit and strengthening their career identity and success. Fishers tend to expand and improve their own boats before getting extra boats. However they face the challenges of capital availability, profitability, personnel and resource concerns when considering reinvestment. The study finds that fishers develop certain dependence on the fish resource. Given the unpredictability of fish landings, fishers maintain commitment to their fishing occupation, expanding boats and increasing their fishing effort to improve their income. While considering oceanic tuna as viable stock for the medium term, fishers are, to some extent, prepared to switch to other fisheries. Fishers do not wish for their children to pursue the occupation of fishing.

description: High pressure water jetting was evaluated as a surface preparation tool for bridge maintenance painting. The tests were conducted on the John F. Kennedy Bridge, which has lead containing existing paint system. The primary concerns were the surface preparation and the lead levels of the wastewater. Test areas were washed at 10,000 psi, 15,000 psi, and 20,000 psi and wastewater was collected for analysis. Lead tests were conducted on unfiltered wastewater and wastewater filtered through a variety of filter fabrics. High-pressure water jetting produces and excellent surface for painting but, on bridges with existing lead paint, the wastewater lead levels are too high for conventional KyDOH filtering requirements.

New effective theories of gravitation and their phenomenological consequences

Publisher: name: arXiv
Year: 2021
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: This thesis focuses on modifications on Einstein's theory of General Relativity, which could explain the current problems in gravitation and cosmology. More specifically, modifications of the affine structure of the spacetime, which is the structure that tells us how to perform derivatives, are studied. These theories appear when imposing that the system must be invariant under the action of the local Poincaré group. Within these theories, their stability, the conditions for the appearance of singularities, the movement of fermions, and if it is possible to find different Black Hole solutions than in Einstein's theory, is explored. Moreover, a non-local extension of the mentioned modification is proposed, which can make the theory free of instabilities and singularities at the linear limit.

description: Superconductivity in high temperature superconducting materials arises due to the constituent electrons becoming strongly correlated. In particular, in the Iron based family of superconductors, antiferromagnetic fluctuations of the electron spins and charge fluctuations of the Iron d-orbitals are thought to be important. The strong correlations of the electrons in an Iron based superconductor lead to the electronic ground state adopting a lower symmetry than the crystal lattice. Transport studies of these systems under the application of uniaxial strain show a strongly anisotropic response of the materials to straining along different lattice directions, suggesting that the electronic correlations are in fact coupled to the lattice. In this thesis I present a study of the response of the magnetic and superconducting states of these Iron based materials to changes of their crystal structure induced by applying uniaxial strain or through doping. I first examine the response of the magnetism in Fe₁₊ₓTe, the parent compound of the Iron chalcogenides, to the change that occurs in the crystal structure as the system is doped with Iron. I present a spin polarized STM study of the magnetism throughout the phase diagram of Fe₁₊ₓTe using in-situ prepared magnetic tips to measure the spin structure. By using the STM tip to remove excess Iron atoms from the surface I show that it is possible to decouple the effects of the excess Iron atoms from the change of crystal structure. Therefore showing the effect of the structural change on the magnetism. Next I present an STM study of how the superconductivity in the tetragonal LiFeAs system responds to the application of uniaxial strain deforming the crystal structure. I describe the construction of a modifed STM sample holder that allows for the in-situ application of a variable Strain to the LiFeAs sample. I present the resulting impact of this straining process to the superconductivity of LiFeAs on an atomic scale and report the formation of a strain induced charge density wave state that coexists with the superconductivity. In the final chapter I report a quasiparticle interference study of the superconducting state of Sulphur doped FeSe and discuss the results in comparison of those from the literature for the undoped FeSe system.

description: The scope of the present paper is the progress of city planning in an area of western Thessaloniki, which is located at a nodal point of the city-complex, and is directly affected by the City's growth dynamic of the previous years. The particular area is a degraded section of the Municipality of Menemeni, that shows a large concentration of both heavy and small industrial plants and warehouses, and is very close to inhabited areas of the Municipality as well as to the not yet build area of Lahanokipi. Lahanokipi of the Municipalities of Menemeni and Thessaloniki is the epicentre of construction development and investments at a metropolitan level, and is therefore the western gate of entrance of the city-complex. Thus, Lahanokipi could become the new receptor of the city's central functions. This perspective leads to the development of a number of special uses in the broader area of the Municipality of Menemeni, and within the context of this paper, the effect that these new uses have on the evolution of that area to a new Peripheral Metropolitan Centre of the Thessaloniki city-complex, shall be examined.

description: Since the first signal in 2015, the gravitational-wave detections of merging binary black holes (BBHs) by the LIGO and Virgo collaborations (LVC) have completely transformed our understanding of the lives and deaths of compact object binaries, and have motivated an enormous amount of theoretical work on the astrophysical origin of these objects. We show that the phenomenological fit to the redshift-dependent merger rate of BBHs from Abbott et al. (2020) is consistent with a purely dynamical origin for these objects, and that the current merger rate of BBHs from the LVC could be explained entirely with globular clusters alone. While this does not prove that globular clusters are the dominant formation channel, we emphasize that many formation scenarios could contribute a significant fraction of the current LVC rate, and that any analysis that assumes a single (or dominant) mechanism for producing BBH mergers is implicitly using a specious astrophysical prior.

description: We investigate properties of attractors for scalar field in the Lorentz violating scalar-vector-tensor theory of gravity. In this framework, both the effective coupling and potential functions determine the stabilities of the fixed points. In the model, we consider the constants of slope of the effective coupling and potential functions which lead to the quadratic effective coupling vector with the (inverse) power-law potential. For the case of purely scalar field, there are only two stable attractor solutions in the inflationary scenario. In the presence of a barotropic fluid, the fluid dominated solution is absent. We find two scaling solutions: the kinetic scaling solution and the scalar field scaling solutions. We show the stable attractors in regions of ($γ$, $ξ$) parameter space and in phase plane plot for different qualitative evolutions. From the standard nucleosynthesis, we derive the constraints for the value of the coupling parameter.

description: The symmetry operators for the Laplacian in flat space were recently described and here we consider the same question for the square of the Laplacian. Again, there is a close connection with conformal geometry. There are three main steps in our construction. The first is to show that the symbol of a symmetry is constrained by an overdetermined partial differential equation. The second is to show existence of symmetries with specified symbol (using a simple version of the AdS/CFT correspondence). The third is to compute the composition of two first order symmetry operators and hence determine the structure of the symmetry algebra. There are some interesting differences as compared to the corresponding results for the Laplacian.

description: We investigate the dynamics of discrete-time quantum walk subject to time correlated noise. Noise is described as an unitary coin-type operator before each step, and attention is focused on the noise generated by a Gaussian Ornstein Uhlenbeck process, going beyond the usual telegraph noise, where the random variables are consist of only -1 and 1. Under the first-order approximation of BCH formula, the master equation of noisy discrete-time quantum walk is derived. The dynamics given by the master equation are in good agreement with those given by numerical simulations within a certain period of steps, which is controlled by noise parameters. Two remarker behaviors of long time noisy dynamics are observed in numerical simulations, corresponding to two opposite noise regimes: in slow noise regime, with the increase of the noise amplitude, the quantum coherence is suppressed, and the dynamics of noisy discrete-time quantum walk gradually transits to that of classical random walk. In fast noise regime, the walker is confined into few lattice sites, and the width of wave packet is much narrower compared with that in slow noise regime.

description: We give a new proof of the Alexander-Wermer Theorem that characterizes the oriented curves in C^n which bound positive holomorphic chains, in terms of the linking numbers of the curve with algebraic cycles in the complement. In fact, we establish a slightly stronger version which applies to a wider class of boundary 1-cycles. Arguments here are based on the Hahn-Banach Theorem and some geometric measure theory. Several ingredients in the original proof have been eliminated.

Nash equilibrium selection in multi-leader multi-follower games with vertical separation
Creators: name: Ceparano, Maria Carmela
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2015

description: The aim of this thesis is twofold. On the one hand  new results on the concavity and  the isotonicity of the optimal solution function of a parametric maximization problem are obtained.  The maximizing function is not required to be continuous and  the  generalized version of the notion of pseudoconcavity in terms of  Dini derivatives is used.
These results, together with a new fixed point theorem for set-valued maps, are  used to answer to the second issue concerning a selection of Nash equilibria, called equilibrium under passive beliefs, of a multi-leader multi-follower game with vertical separation and partially observed actions. Indeed, an equilibrium under passive beliefs correspond to a fixed point of particular set-valued maps related to the sets of solutions of parametric bilevel optimization problems. Existence of equilibria under passive beliefs for significative classes of problems and conditions of minimal character on data possibly discontinuous are proved.
An economic example of such interaction can be found in games of multilateral vertical contracts: competing manufacturers (the leaders) delegate retail decisions to exclusive retailers (the followers), offering a private contract.

description: Point spread function (PSF) engineering of the emitter can code higher spatial frequency information of an image to break diffraction limit but suffer from the complexed optical systems. Here we present a robust strategy to simultaneously achieve diverse PSFs from upconversion nanoparticles under a single doughnut-shape scanning beam. By saturating the four-photon state, the high-frequency information can be extracted through the doughnut emission PSF. In contrast, the complementary lower frequency information can be carried out by the Gaussian-like emission PSF, as a result of over-saturated at the two-photon state. With the Fourier domain heterochromatic fusion, we verify the capability of the synthesised PSF to cover both low and high-frequency information, yielding the overall enhanced image quality. We show a spatial resolution of 40 nm, 1/24th of the excitation wavelength. This work suggests a new scope for developing nonlinear multi-colour emitting probes to improve image quality and noise control in nanoscopy.

description: Vision in Motion is a lasting theoretical proposal left by one of Modernism's great artists - Laszlo Moholy-Nagy. Operating as an account of the curriculum for The Institute of Design, which he founded in Chicago, Vision in Motion proposes a democratic vision of self-expression, one that emphasises the necessity of integrating art with life. His proposal that we learn to utilise all our sensory capacities and to see everything in relationship, emphasises simultaneity and motion through the interconnection of space and time. In doing so Moholy-Nagy proposes a theory of perception and of change, which is dynamic and fitting for the modern age. This thesis will propose that another artist operating in similar fields at the same time was intuitively exploring many of these ideas: Len Lye; a New Zealander whose art practice paralleled and intersected with Moholy-Nagy's as an experimental film maker and kinetic sculptor. Where Moholy-Nagy's life-long pursuit was of the expression of light, Lye's was of motion, but both artists shared similar complexities in their work in regards to the treatment of space and time, responding to the annihilation of time and space as a result of 19th century technological and scientific developments. Yann Beauvais' essay "Rapports entre Len Lye et Moholy-Nagy" is the departure point for this thesis, using the concept of 'Vision in Motion' to investigate further the conjectures and differences between these two artists. In doing so this thesis aims to demonstrate that Lye was the exemplary artist that Moholy-Nagy theorised about, adding further prominence to the recognition of Lye as one of the great visionaries of interdisciplinary practice and Modernism.

description: The physical properties of faint stellar and substellar objects often rely on indirect, model-dependent estimates. For example, the masses of brown dwarfs are usually inferred using evolutionary models, which are age dependent and have yet to be properly calibrated. With the goal of identifying new benchmark objects to test low-mass stellar and substellar models, we have carried out a comprehensive adaptive optics survey as part of the TaRgetting bENchmark-objects with the Doppler Spectroscopy high-contrast imaging program. Using legacy radial velocity measurements from High Resolution Echelle Spectrometer at Keck, we have identified several dozen stars that show long-term Doppler accelerations. We present follow-up high-contrast observations from the campaign and report the discovery of 31 co-moving companions, as well as 11 strong candidate companions, to solar-type stars with well-determined parallax and metallicity values. Benchmark objects of this nature lend themselves to orbit determinations, dynamical mass estimates, and independent compositional assessment. This compendium of benchmark objects will serve as a convenient test group to substantiate theoretical evolutionary and atmospheric models near the hydrogen fusing limit.

description: We report observations of Crab giant pulses made with the Australia Telescope Compact Array and a baseband recorder system, made simultaneously at two frequencies, 1300 and 1470 MHz. These observations were sensitive to pulses with amplitudes \ga 3 kJy and widths \ga 0.5 $μ$s. Our analysis led to the detection of more than 700 such bright giant pulses over 3 hours, and using this large sample we investigate their amplitude, width, arrival time and energy distributions. The brightest pulse detected in our data has a peak amplitude of $\sim$ 45 kJy and a width of $\sim$ 0.5 $μ$s, and therefore an inferred brightness temperature of $\sim 10^{35}$ K. The duration of giant-pulse emission is typically $\sim$1 $μ$s, however it can also be as long as 10 $μ$s. The pulse shape at a high time resolution (128 ns) shows rich diversity and complexity in structure and is marked by an unusually low degree of scattering. We discuss possible implications for scattering due to the nebula, and for underlying structures and electron densities.

description: The major aspect of this research is the development of a variable-energy PALS beamline based on a Surko-type buffer gas positron trap, the first of its kind in the world. A significant amount of work has gone into optimization of the timing and intensity characteristics of positron pulse. Successful implantation of 'Mills ideal function' bunching method has led to positron pulses of 800ps, allowing depth selective studies across a range of defect sizes, from point defects with lifetimes as low as 200ps, to large voids (~10 nm) resulting in lifetimes >50 ns. In addition to experimental development aspects, the materials investigations presented here focus on defects in semiconductor materials produced by ion implantation and focused laser pulses. The PALS beamline was used to demonstrate the suppression of void formation due to the Si/Si0{u2082} interface in Helium ion implanted silicon-on-insulator (SOl). Vacancy clustering in self-ion-implanted Germanium has also been studied using both the PALS beamline and Rutherford Backscattering Spectroscopy (RBS). The evolution of the ion implantation induced damage during annealing was investigated with results indicating that vacancy cluster occurs in both crystalline and amorphous states. In gallium antimonide, positrons were used to probe void formation in swift heavy ion implantation at various fluences, leading to a better understanding of the transition between isolated channels and heavily porous states as the ion implantation fluence increases. Finally, the positron beamline was used to study the large voids produced by focused femtosecond laser pulses in fused silica, where lifetimes associated with o-Ps annihilation in 0{u2082} filled voids were observed. By combining the PALS measurements with TEM images, the residual 0{u2082} pressure inside the voids after isochronal annealing was estimated and compared with expected values from Monte-Carlo simulations.

description: In previous work, we have considered Hamiltonians associated with 3 dimensional conformally flat spaces, possessing 2, 3 and 4 dimensional isometry algebras. Previously our Hamiltonians have represented free motion, but here we consider the problem of adding potential functions in the presence of symmetry. Separable potentials in the 3 dimensional space reduce to 3 or 4 parameter potentials for Darboux-Koenigs Hamiltonians. Other 3D coordinate systems reveal connections between Darboux-Koenigs and other well known super-integrable Hamiltonians, such as the Kepler problem and isotropic oscillator.

The nature and origins of sub-Neptune size planets

description: Planets intermediate in size between the Earth and Neptune, and orbiting closer to their host stars than Mercury does the Sun, are the most common type of planet revealed by exoplanet surveys over the last quarter century. Results from NASA's Kepler mission have revealed a bimodality in the radius distribution of these objects, with a relative underabundance of planets between 1.5 and 2.0 $R_{\oplus}$. This bimodality suggests that sub-Neptunes are mostly rocky planets that were born with primary atmospheres a few percent by mass accreted from the protoplanetary nebula. Planets above the radius gap were able to retain their atmospheres ("gas-rich super-Earths"), while planets below the radius gap lost their atmospheres and are stripped cores ("true super-Earths"). The mechanism that drives atmospheric loss for these planets remains an outstanding question, with photoevaporation and core-powered mass loss being the prime candidates. As with the mass-loss mechanism, there are two contenders for the origins of the solids in sub-Neptune planets: the migration model involves the growth and migration of embryos from beyond the ice line, while the drift model involves inward-drifting pebbles that coagulate to form planets close-in. Atmospheric studies have the potential to break degeneracies in interior structure models and place additional constraints on the origins of these planets. However, most atmospheric characterization efforts have been confounded by aerosols. Observations with upcoming facilities are expected to finally reveal the atmospheric compositions of these worlds, which are arguably the first fundamentally new type of planetary object identified from the study of exoplanets.

High Fidelity Single-Qubit Gates Using Non-adiabatic Rapid Passage

description: Numerical simulation results are presented which suggest that a class of non-adiabatic rapid passage sweeps first realized experimentally in 1991 should be capable of implementing a set of quantum gates that is universal for one-qubit unitary operations and whose elements operate with error probabilities per operation P < 10^{-4}. The sweeps are non-composite and generate controllable quantum interference effects which allow the one-qubit gates produced to operate non-adiabatically while maintaining high accuracy. The simulations suggest that the one-qubit gates produced by these sweeps show promise as possible elements of a fault-tolerant scheme for quantum computing.

description: The introduction of Health Education in education was the motive for carrying out several investigations in the area of school, family and society in general. In particular, the relationship of certain factors relating to the circumstances and lifestyles , the causality or the prevention of cancer, has been demonstrated in many modern studies, which reveals that many cancers could be prevented. This thesis was based on the results of quantitative research carried out in Aristotle University of Thessaloniki, Greece, identifying and recording the knowledge, attitudes and behaviour of students on issues referring to the prevention of carcinogenesis. In the research there I also a comparison of the results with those of a survey undertaken by the respective sample ,a decade ago in the same university in order to record and interpret possible variations.
Astronomical Image Subtraction by Cross-Convolution

Subjects: subject: Astrophysics (astro-ph)

description: In recent years, there has been a proliferation of wide-field sky surveys to search for a variety of transient objects. Using relatively short focal lengths, the optics of these systems produce undersampled stellar images often marred by a variety of aberrations. As participants in such activities, we have developed a new algorithm for image subtraction that no longer requires high quality reference images for comparison. The computational efficiency is comparable with similar procedures currently in use. The general technique is cross-convolution: two convolution kernels are generated to make a test image and a reference image separately transform to match as closely as possible. In analogy to the optimization technique for generating smoothing splines, the inclusion of an RMS width penalty term constrains the diffusion of stellar images. In addition, by evaluating the convolution kernels on uniformly spaced subimages across the total area, these routines can accomodate point spread functions that vary considerably across the focal plane.
