description: A Geant4-based Monte Carlo model for Heavy-Ion Therapy (MCHIT) is used to study radiation fields of H-1, He-4, Li-7 and C-12 beams with similar ranges (~160-180 mm) in water. Microdosimetry spectra are simulated for wall-less and walled Tissue Equivalent Proportional Counters (TEPCs) placed outside or inside a phantom, as in experiments performed, respectively, at NIRS, Japan and GSI, Germany. The impact of fragmentation reactions on microdosimetry spectra is investigated for He-4, Li-7 and C-12, and contributions from nuclear fragments of different charge are evaluated for various TEPC positions in the phantom. The microdosimetry spectra measured on the beam axis are well described by MCHIT, in particular, in the vicinity of the Bragg peak. However, the simulated spectra for the walled TEPC far from the beam axis are underestimated. Relative Biological Effectiveness (RBE) of the considered beams is estimated using a modified microdosimetric-kinetic model. Calculations show a similar rise of the RBE up to 2.2-2.9 close to the Bragg peak for helium, lithium and carbon beams compared to the modest values of 1-1.2 at the plateau region. Our results suggest that helium and lithium beams are also promising options for cancer therapy.

description: We study the heavy quark scattering on partons of the quark gluon plasma (QGP) being especially interested in the collisional (elastic) scattering processes of heavy quarks on quarks and gluons. We calculate the different cross sections for perturbative partons (massless on-shell particles in the vacuum) and for dynamical quasi-particles (off-shell particles in the QGP medium as described by the dynamical quasi-particles model "DQPM") using the leading order Born diagrams. Our results show clearly the effect of a finite parton mass and width on the perturbative elastic $(q(g) Q \rightarrow q (g) Q)$ cross sections which depend on temperature $T$, energy density $ε$, the invariant energy $\sqrt{s}$ and the scattering angle $θ$. Our detailed comparisons demonstrate that the finite width of the quasi-particles in the DQPM - which encodes the multiple partonic scattering - has little influence on the cross section for $q Q \rightarrow q Q$ as well as $g Q \rightarrow g Q$ scattering except close to thresholds. Thus when studying the dynamics of energetic heavy quarks in a QGP medium the spectral width of the degrees-of-freedom may be discarded. We have, furthermore, compared the cross sections from the DQPM with corresponding results from hard-thermal-loop (HTL) approaches. The HTL inspired models - essentially fixing the regulators by elementary vacuum cross sections and decay amplitudes instead of properties of the QGP at finite temperature - provide quite different results especially w.r.t. the temperature dependence of the $qQ$ and $gQ$ cross sections (in all settings). Accordingly, the transport properties of heavy quarks will be very different as a function of temperature when compared to DQPM results.

 Abstract.
 HTTP-Based Adaptive Streaming (HAS) has been widely adopted for video streaming over the Internet, because it can serve a large variety of heterogeneous clients. Each client expe- riences different network conditions, which can rapidly change during a streaming session. Therefore, one of the main streaming challenges is adjusting the streaming settings in order to maximize Quality of Experience (QoE). QoE is defined as minimizing playback disrup- tions along with quality transitions while maximizing video quality [18]. Additionally, low latencies are required for live streaming. Streaming over HTTP requires the client to retrieve the video in form of segments from a server via HTTP requests. Hence, in live streaming a minimal delay of one segment duration is introduced because the request can only be sent when the segment is completely created. Reducing the segment duration allows segments to be delivered to the client sooner. Nevertheless, as a result of the increased number of requests, the added overhead has a negative impact on the video transmission. Moreover, reducing the segment duration implies having faster reaction time to fluctuations in bandwidth changes. We provide software components to reduce latency in live streaming sessions. To counter the overhead of reduced segment durations, we use the HTTP/2 Server Push and request cancelling features. The aim of this thesis is to reduce the usual delay of 30 seconds during live transmissions to under 5 seconds.

description: The planet occurrence rate for multiple stars is important in two aspects. First, almost half of stellar systems in the solar neighborhood are multiple systems. Second, the comparison of the planet occurrence rate for multiple stars to that for single stars sheds light on the influence of stellar multiplicity on planet formation and evolution. We developed a method of distinguishing planet occurrence rates for single and multiple stars. From a sample of 138 bright (KP <13.5) Kepler multi-planet candidate systems, we compared the stellar multiplicity rate of these planet host stars to that of field stars. Using dynamical stability analyses and archival Doppler measurements, we find that the stellar multiplicity rate of planet host stars is significantly lower than field stars for semi-major axes less than 20 AU, suggesting that planet formation and evolution are suppressed by the presence of a close-in companion star at these separations. The influence of stellar multiplicity at larger separations is uncertain because of search in- completeness due to a limited Doppler observation time baseline and a lack of high resolution imaging observation. We calculated the planet confidence for the sample of mutlti-planet candidates, and find that the planet confidences for KOI 82.01, KOI 115.01, KOI 282.01 and KOI 1781.02 are higher than 99.7% and thus validate the planetary nature of these four planet candidates. This sample of bright Kepler multi-planet candidates with refined stellar and orbital parameters, planet confidence estimation, and nearby stellar companion identification offers a well-characterized sample for future theoretical and observational study.

description: We investigate the orbifold limits of string theory compactifications with geometric and non-geometric fluxes. Exploiting the connection between internal fluxes and structure constants of the gaugings in the reduced supergravity theory, we can identify the types of fluxes arising in certain classes of freely-acting symmetric and asymmetric orbifolds. We give a general procedure for deriving the gauge algebra of the effective gauged supergravity using the exact CFT description at the orbifold point. We find that the asymmetry is, in general, related to the presence of non-geometric Q- and R- fluxes. The action of T-duality is studied explicitly on various orbifold models and the resulting transformation of the fluxes is derived. Several explicit examples are provided, including compactifications with geometric fluxes, Q-backgrounds (T-folds) and R-backgrounds. In particular, we present an asymmetric Z4xZ2 orbifold in which all geometric and non-geometric fluxes ω, H, Q, R are turned on simultaneously. We also derive the corresponding flux backgrounds, which are not in general T-dual to geometric ones, and may even simultaneously depend non-trivially on both the coordinates and their winding T-duals.

description: We study the evolution of atomic and molecular gas in galaxies in semi-analytic models of galaxy formation that include new modeling of the partitioning of cold gas in galactic discs into atomic, molecular, and ionised phases. We adopt two scenarios for the formation of molecules: one pressure-based and one metallicity-based. We find that both recipes successfully reproduce the gas fractions and gas-to-stellar mass ratios of HI and H2 in local galaxies,as well as the HI and H2 disc sizes up to z<2. We reach good agreement with the locally observed HI and H2 mass function, although both recipes slightly overpredict the low-mass end of the HI mass function. Both of our models predict that the high-mass end of the HI mass function remains nearly constant at redshifts z < 2.0. The metallicity-based recipe yields a higher cosmic density of cold gas and much lower cosmic H2 fraction over the entire redshift range probed than the pressure based recipe. These strong differences in HI mass function and cosmic density between the two recipes are driven by low mass galaxies (log (M*/Msun) < 7) residing in low mass halos (log (Mvir/Msun) < 10). Both recipes predict that galaxy gas fractions remain high from z ~ 6-3 and drop rapidly at lower redshift. The galaxy H2 fractions show a similar trend, but drop even more rapidly. We provide predictions for the CO J = 1-0 luminosity of galaxies, which will be directly comparable with observations with sub-mm and radio instruments.

description: We propose an experimental scheme to realize the valley-dependent gauge fields for ultracold fermionic atoms trapped in a state-dependent square optical lattice. Our scheme relies on two sets of Raman laser beams to engineer the hopping between adjacent sites populated by two-component fermionic atoms. One set of Raman beams are used to realize a staggered π-flux lattice, where low energy atoms near two inequivalent Dirac points should be described by the Dirac equation for spin-1/2 particles. Another set of laser beams with proper Rabi frequencies are added to further modulate the atomic hopping parameters. The hopping modulation will give rise to effective gauge potentials with opposite signs near the two valleys, mimicking the interesting strain-induced pseudo-gauge fields in graphene. The proposed valley-dependent gauge fields are tunable and provide a new route to realize quantum valley Hall effects and atomic valleytronics.

description: Bio-oils are a promising renewable and carbon-neutral hydrocarbon material that can become a new energy source. Bio-oil mixtures have complex multi-component composition consisting of the pyrolysis products of cellulose, hemicellulose, and lignin of various molecular sizes with a range of highly oxygenated functional groups. Chemical characterization of bio-oil components is therefore necessary to inform the upgrading process of bio-oil and improve its commercial viability. We utilize aerosol technology to facilitate characterization of bio-oil components resulting in compositional differences specific to its volatility-separated fractions. We aerosolize bio-oil mixture, followed by size separation and collection of obtained particles using a cascade impactor, where the collected particles are exposed to sequentially reduced pressures at each of the impaction stages. We characterize components of the impactor separated bio-oil fractions using high-resolution mass spectrometry equipped with interchangeable electrospray ionization and dopant-assisted atmospheric pressure photoionization sources. Through examination of the detected chemical species in each of the separated fractions and assessment of their physiochemical properties, we identify a range of fuel-like aliphatic species with low O/C ratio and low viscosity in the most volatile fraction. The less volatile fractions contained progressively higher portions of more viscous species containing lignin and sugars moieties with characteristic high O/C values. We show that the impactor-based separation of bio-oil fractions facilitates comprehensive characterization of its components with varying fuel viability, capable of guiding upgrading processes.

description: We study some aspects of the generalized geometry of nilmanifolds and examine to which extent different types of fluxes can coexist on them. Nilmanifolds constitute a class of homogeneous spaces which are interesting in string compactifications with fluxes since they carry geometric flux by construction. They are generalized Calabi-Yau spaces and therefore simple examples of generalized geometry at work. We identify and classify Dirac structures on nilmanifolds, which are maximally isotropic subbundles closed under the Courant bracket. In the presence of non-vanishing fluxes, these structures are twisted and closed under appropriate extensions of the Courant bracket. Twisted Dirac structures on a nilmanifold may carry multiple coexistent fluxes of any type. We also show how dual Dirac structures combine to Courant algebroids and work out an explicit example where all types of generalized fluxes coexist. These results may be useful in the context of general flux compactifications in string theory.

description: In this paper, we define a stochastic calculus with respect to the Rosenblatt process by means of white noise distribution theory. For this purpose, we compute the translated characteristic function of the Rosenblatt process at time $t>0$ in any direction $ξ\in S(\mathbb{R})$ and the derivative of the Rosenblatt process in the white noise sense. Using Wick multiplication by the former derivative and Pettis integration, we define our stochastic integral with respect to the Rosenblatt process for a wide class of distribution processes. We obtain an explicit formula for the variance of such a stochastic integral and Itô's formulae for a certain class of functionals of the Rosenblatt process. Finally, we compare our stochastic integral to other approaches.
title: Oaths, kings and subjects : a study of the oaths sworn to kings by subjects in England, c.870-c,1200
Creators: name: Hey, Joshua
Publisher: name: University of St Andrews
Year: 2018

description: This thesis is a study of the oaths sworn by subjects to kings of England between c. 870 and c. 1200. Who swore oaths to the king? When did they swear? What sorts of oaths were sworn? What commitments did swearing lead to? Where were oaths sworn, and what rituals were involved in swearing? These are some of the questions asked of the evidence, a combination of narrative and legal sources. This material is examined over four thematic chapters. The first three look at oaths sworn ordinarily at the time of accessions, as part of succession planning, and within the confines of reigns themselves, respectively. The final chapter examines oaths sworn outside of this process—oaths sworn in non-normal, extraordinary circumstances.
Redundant Automation Monitoring: Four Eyes Don’t See More Than Two, if Everyone Turns a Blind Eye

description: Background: In safety-critical and highly automated environments, more than one person typically monitors the system in order to increase reliability. Objective: We investigate whether the anticipated advantage of redundant automation monitoring is lost due to social loafing and whether individual performance feedback can mitigate this effect. Method: In two experiments, participants worked on a multitasking paradigm in which one task was the monitoring and cross-checking of an automation. Participants worked either alone or with a team partner on this task. The redundant group was further subdivided. One subgroup was instructed that only team performance would be evaluated, whereas the other subgroup expected to receive individual performance feedback after the experiment. Results: Compared to participants working alone, those who worked collectively but did not expect individual feedback performed significantly less cross-checks and found 25% fewer automation failures. Due to this social loafing effect, even the combined team performance did not surpass the performance of participants working alone. However, when participants expected individual performance feedback, their monitoring behavior and failure detection performance was similar to participants working alone and a team advantage became apparent. Conclusion: Social loafing in redundant automation monitoring can negate the expected gain, if individual performance feedback is not provided. Application: These findings may motivate safety experts to evaluate whether their implementation of human redundancy is vulnerable to social loafing effects.

description: In this work we show that modifying the thermal history of the Universe by including an early period of matter domination can lead to the formation of astronomical objects. However, the survival of these objects can only be possible if the dominating matter decays to a daughter particle which is not only almost degenerate with the parent particle but also has an open coannihilation channel. This requirement translates in an upper bound for the coupling of such a channel and makes the early structure formation viable.

description: Respiratory aerosols arise due to bronchial fluid film bursting within the pulmonary tract, the vibration of the vocal folds during phonation, and articulation of the tongue/lips/teeth. We expect respiratory aerosol emission rates to be lower in children than adults due to the smaller size of their laryngeal structure, reduced sub-glottal pressure created during speech, and reduced number of alveoli. However, few studies have evaluated respiratory aerosols for children. We recruited 50 participants from three age categories: children aged 6–11 years, children aged 12–18 years, and adults (>18 years). We investigated particle emissions for three different 5 s sustained vocalizations of /a/ or /pa/ at 262 Hz, as well as for running speech and breathing. The particle generation rate ranged from 0 to 488 particles/s. Children aged 6–11 years produced fewer particles (mean 12 ± SD 9 particles/s) than children aged 12–18 years (23 ± 19 particles/s) and adults (70 ± 73 particles/s). Taking a deep breath before vocalizing /a/ resulted in higher aerosol emission rates than the baseline case. The particle number size distributions for all vocalizations and age groups consistently showed two modes at ≈0.6 μm and ≈2 μm. Children had a slightly smaller primary mode location and larger secondary mode location than adults. Superemitters (statistical outliers) were found in all groups. Experiments repeated over time revealed large intrapersonal variability indicating additional variables (e.g., environmental, physiological, behavioral) may significantly influence emission rates. The lower respiratory aerosol emission rates for children indicate a need to consider population demographics when predicting airborne disease transmission risks.

description: We study the simple hypothesis testing problem for the drift coefficient for stochastic fractional heat equation driven by additive noise. We introduce the notion of asymptotically the most powerful test, and find explicit forms of such tests in two asymptotic regimes: large time asymptotics, and increasing number of Fourier modes. The proposed statistics are derived based on Maximum Likelihood Ratio. Additionally, we obtain a series of important technical results of independent interest: we find the cumulant generating function of the log-likelihood ratio; obtain sharp large deviation type results for $T\to\infty$ and $N\to\infty$.

 Abstract.
 Our expectations of Explainable AI have grown together with its popularity. So far, the interpretability technique of Layer-Wise Relevance Propagation (LRP) has been adopted with mostly qualitative evaluation of its rules. Therefore, a quantitative and qualitative evaluation of LRP rules is conducted to determine which hyperparameters provide the best scoring heatmaps according to the Pixel-Flipping and Area Under the Curve evaluation framework. It can be concluded from the experiment results that the choice of evaluation metrics and visualization of heatmaps has a significant impact on explanations. Additionally, due to the inherent subjectivity of visual explanations the requirements should be defined on a case-by-case basis.

description: The accurate measurement of PM2.5 and its inorganic matters (IMs) is crucial for compliance monitoring and understanding particle formation. However, semi-volatile IMs (SVIMs) like NH4+, NO3−, and Cl− tend to evaporate from particles, causing sampling artifacts. The evaporation loss occurs due to many factors making the quantitative prediction difficult. This study aimed to investigate the evaporation loss of SVIMs in PM2.5 under different sampling conditions. In the field tests, when a normal single Teflon filter (STF) sampler, which is like a Federal Reference Method (FRM) sampler, was used to sample PM2.5 at ambient conditions, a significant SVIM evaporation loss was observed, resulting in negative biases for total IMs (−25.68 ± 3.25%) and PM2.5 concentrations (−9.87 ± 4.27%). But if PM2.5 was sampled by a chilled Teflon filter sampler (CTF) at 4 °C following aerosol dehumidification so that relative humidity (RH) was controlled to within the 10–20% range (RHd), evaporation loss was minimized with a bias of < ±10% for both total IMs and PM2.5 based on the reference data. When RHd is below 10%, both IMs and PM2.5 are under-measured, but only PM2.5 is over-measured when RHd is >20%. A model considering predictable saturation ratios for NH4+, NO3−, and Cl− under various pressure drop, temperature and RH conditions was developed to predict accurately the actual concentrations of PM2.5 and its SVIMs for the STF. Additionally, the ISORROPIA-II model predicted SVIMs effectively for the CTF. In summary, using the CTF at optimized sampling conditions can achieve accurate measurement of both SVIMs and PM2.5 concentrations simultaneously.

Cooling of atomic ensembles in optical cavities: Semiclassical limit

description: The semiclassical dynamics of atoms are theoretically studied, when the atoms are confined inside a standing-wave high-finesse resonator. The atoms are cooled by scattering processes in which the photons of a transverse laser are coherently scattered into the cavity mode. We derive a Fokker-Planck equation for the atomic center-of-mass variables which allows us to determine the equations of motion in the semiclassical limit for any value of the intensity of the laser field. We extract its prediction for the dynamics when the resonator is essentially in the vacuum state and the atoms are cooled by scattering photons into the cavity mode, which then decays. Its predictions for the stationary atomic distribution are compared with the ones of the Fokker-Planck equation in [P. Domokos, P. Horak, and H. Ritsch, J. Phys. B 34, 187 (2001)], which has been derived under different assumptions. We find full agreement in the considered parameter regime.

Floquet Theory of Electron Waiting Times in Quantum-Coherent Conductors

description: We present a Floquet scattering theory of electron waiting time distributions in periodically driven quantum conductors. We employ a second-quantized formulation that allows us to relate the waiting time distribution to the Floquet scattering matrix of the system. As an application we evaluate the electron waiting times for a quantum point contact, modulating either the applied voltage (external driving) or the transmission probability (internal driving) periodically in time. Lorentzian-shaped voltage pulses are of particular interest as they lead to the emission of clean single-particle excitations as recently demonstrated experimentally. The distributions of waiting times provide us with a detailed characterization of the dynamical properties of the quantum-coherent conductor in addition to what can be obtained from the shot noise or the full counting statistics.

description: Orbital angular momentum (OAM) of graphene electrons in a perpendicular magnetic field is calculated and corresponding magnetic moment is used to investigate the magnetism of perfect graphene. Variation in magnetization demonstrates its decrease with carrier-doping, plateaus in a large field, and de Haas-van Alphen oscillation. Regulation of magnetism by a parallel electric field is presented. The OAM originates from atomic-scale electronic motion in graphene lattice, and vector hopping interaction between carbon atomic orbitals is the building element. A comparison between OAM of graphene electrons, OAM of Dirac fermions, and total angular momentum of the latter demonstrates their different roles in magnetism of graphene. Applicability and relation to experiments of the results are discussed.

description: A detailed study of nucleon parton distribution functions is performed within a radiative Next-to-Next-to Leading Order (NNLO) parton model whose low-scale input is rigidly described by wave functions which include quarks and dressing meson-cloud. The light-front Hamiltonian dynamics fixes the three-quark wave functions and the meson cloud is introduced by means of high-order Fock component in time-ordered perturbation theory in the infinite momentum frame. Non-strange as well as strange mesons-baryon fluctuations are considered ($π$, $ρ$, $ω$, $K$ and $K^*$, together with $N$, $Δ$, $Λ$ and $Σ$) and the effects on strange and non-strange parton distributions investigated showing the large effects due to (non-strange) sea asymmetries and the delicate balance of the strange asymmetry. The non-strange and the strange components, the valence as well as the gluon distributions are compared with available experimental data confirming the need of both non-perturbative degrees of freedom and perturbative (NNLO) radiative effects.

description: We investigate the impact of direct LHC SUSY searches on the parameter space of three natural scenarios in the MSSM. In the first case the spectrum consists of light stops, sbottoms, and Higgsino-like neutralinos, while the other particles are assumed to be out of the experimental reach. In the second case we consider an additional light gluino. Finally we study a more complex spectrum comprising also light sleptons, a wino-like chargino, and a bino-like neutralino. We simulate in detail three LHC searches: stop production at ATLAS with 20.7/fb, CMS 11.7/fb inclusive search for squarks and gluinos with the variable α_T, and CMS 9.2/fb electroweak production with 3 leptons in the final state. For each point in our scans we calculate the exclusion likelihood due to the individual searches and to their statistical combination. We calculate the fine-tuning measure of the points allowed by the LHC and the implications for the Higgs mass and other phenomenological observables: Higgs signal rates, the relic density, BR(Bs --> μ^+μ^-), BR(B --> Xs γ), and the spin-independent neutralino-proton scattering cross section. We find that points with acceptable levels of fine-tuning are for the most part already excluded by the LHC and including the other constraints further reduces the overall naturalness of our scenarios.
