description: We construct SU($N$) super Yang-Mills theories with extended supersymmetry on hypercubic lattices of various dimensions keeping one or two supercharges exactly. It is based on topological field theory formulation for the super Yang-Mills theories. Gauge fields are represented by compact unitary link variables, and the exact supercharges on the lattice are nilpotent up to gauge transformations. In particular, the lattice models are free from the vacuum degeneracy problem, which was encountered in earlier approaches. Thus, we do not need to introduce any supersymmetry breaking terms, and the exact supersymmetry is preserved wholly in the process of taking the continuum limit. Among the models, we show that the desired continuum theories are obtained without any fine tuning of parameters for the cases ${\cal N}=2, 4, 8$ in two-dimensions. Also, the cases ${\cal N}=4, 8$ in three-dimensions are investigated, and a problem arising in four-dimensional models is discussed.

Gait assessment of dairy cattle
Creators: name: Flower, Frances Claire
Publisher: name: University of British Columbia
Year: 2010

description: Hoof and leg pathologies are important to the welfare of dairy cows and the profitability of farms; however, to date researchers have had little success in detecting cows with hoof pathologies using current gait analysis methods which are poorly defined and un-validated. The first aim of my thesis was to describe the walking gait profile of cows with no visible hoof pathologies, compare this with profiles of cows with sole haemorrhages, and cows with sole ulcers, and determine which gait measures were valid and reliable indicators of hoof pathologies. The second aim of my thesis was to examine how udder size and flooring surface influenced the way cows walk, and how these effects varied for cows with different hoof pathologies. Analyses of cow gait, using kinematic techniques and subjective gait assessment, showed distinct differences among cows with no visible hoof pathologies compared to those with painful sole ulcers. Cows with sole ulcers probably walked differently to reduce loading on the affected leg. The gait pattern of cows before and after milking was also different; cows had longer strides and walked more quickly after milking. These results suggest that the most suitable time to conduct on-farm assessments of dairy cattle gait is after milking. Rubber flooring improved the gait of both cows with and without sole ulcers. Lame cattle showed the greatest improvement, suggesting that rubber flooring provided a more secure and comfortable surface for cows to walk on. This research provides novel contributions to the field of dairy cattle lameness; this research was the first study to quantify and validate the gait of cows with and without hoof pathologies using computer-aided kinematic techniques and was also the first to explicitly define, validate, and test the reliability of an overall gait score and individual behavioural gait attributes. Although there is still much work to be done to better understand how hoof and leg pathologies affect cows, the research described here provides insight into how dairy cows with and without hoof pathologies walk and how certain variables such as milking and flooring influence cow walking patterns.

description: Király in [On maximal independent arborescence packing, SIAM J. Discrete. Math. 30 (4) (2016), 2107-2114] solved the following packing problem: Given a digraph $D = (V, A)$, a matroid $M$ on a set $S = \{s_{1}, \ldots,s_{k} \}$ along with a map $π: S \rightarrow V$, find $k$ arc-disjoint maximal arborescences $T_{1}, \ldots ,T_{k}$ with roots $π(s_{1}), \ldots ,π(s_{k})$, such that, for any $v \in V$, the set $\{s_{i} : v \in V(T_{i})\}$ is independent and its rank reaches the theoretical maximum. In this paper, we give a new characterization for packing of maximal independent mixed arborescences under matroid constraints. This new characterization is simplified to the form of finding a supermodular function that should be covered by an orientation of each strong component of a matroid-based rooted mixed graph. Our proofs come along with a polynomial-time algorithm. Note that our new characterization extends Király's result to mixed graphs, this answers a question that has already attracted some attentions.

description: Current speaker verification techniques rely on a neural network to extract speaker representations. The successful x-vector architecture is a Time Delay Neural Network (TDNN) that applies statistics pooling to project variable-length utterances into fixed-length speaker characterizing embeddings. In this paper, we propose multiple enhancements to this architecture based on recent trends in the related fields of face verification and computer vision. Firstly, the initial frame layers can be restructured into 1-dimensional Res2Net modules with impactful skip connections. Similarly to SE-ResNet, we introduce Squeeze-and-Excitation blocks in these modules to explicitly model channel interdependencies. The SE block expands the temporal context of the frame layer by rescaling the channels according to global properties of the recording. Secondly, neural networks are known to learn hierarchical features, with each layer operating on a different level of complexity. To leverage this complementary information, we aggregate and propagate features of different hierarchical levels. Finally, we improve the statistics pooling module with channel-dependent frame attention. This enables the network to focus on different subsets of frames during each of the channel's statistics estimation. The proposed ECAPA-TDNN architecture significantly outperforms state-of-the-art TDNN based systems on the VoxCeleb test sets and the 2019 VoxCeleb Speaker Recognition Challenge.

description: In the present work a simple analytical approach is presented in order to clarify the physics behind the edge current density behaviour of a hot plasma entering in contact with a resistive conductor. When a plasma enters in contact with a highly resistive wall, large current densities appear at the edge of the plasma. The model shows that this edge current originates from the plasma response, which attempts to conserve the poloidal magnetic flux ($Ψ$) when the outer current is being lost. The loss of outer current is caused by the high resistance of the outer current path compared to the plasma core resistance. The resistance of the outer path may be given by plasma contact with a very resistive structure or by a sudden decrease of the outer plasma temperature (e.g. due to a partial thermal quench or due to a cold front penetration caused by massive gas injection). For general plasma geometries and current density profiles the model shows that given a small change of minor radius ($δa$) the plasma current is conserved to first order ($δI_p = 0 + \mathcal{O}(δa^2)$). This conservation comes from the fact that total inductance remains constant ($δL = 0$) due to an exact compensation of the change of external inductance with the change of internal inductance ($δL_\text{ext}+δL_\text{int} = 0$). As the total current is conserved and the plasma volume is reduced, the edge safety factor drops according to $q_a \propto a^2/I_p$. Finally the consistency of the resulting analytical predictions is checked with the help of free-boundary MHD simulations.

title: Sequence analysis of the merozoite surface protein 7 (PvMSP-7) multigene family: vaccine candidates for Plasmodium vivax
Creators: name: Cheng, C
Publisher: name: University of Liverpool Repository
Year: 2019

description: P. vivax is found predominantly in Asia and the emergence of resistance to antimalarial drug and insecticides are major challenges to control of vivax malaria. Control is further complicated by the dormant liver stage of P. vivax, which produces an asymptomatic parasite reservoir. Malaria vaccine development is recognised as the most efficient control intervention globally. Currently, malaria vaccine development is concentrated in P. falciparum and RTS,S has been the most promising vaccine. This has encouraged similar initiatives to develop a P. vivax vaccine. The subject of this thesis is the Plasmodium vivax merozoite surface protein 7 (PvMSP-7), which forms a multi-protein complex with other merozoite surface proteins and plays a principal role in erythrocyte invasion. Studies in P. falciparum have shown that targeting MSP-7 can impair erythrocyte invasion and regulate disease severity. For this reason, PvMSP-7 is a plausible vaccine candidate. However, several questions remain to be addressed before a vaccine can be developed; (i) the antigenic variation and expression pattern of the PvMSP-7 multigene family, (ii) which PvMSP-7 paralog is the most promising target, and (iii) which domain of the protein is most antigenically relevant. The main aim of this thesis is to characterise the structural and expression variation in PvMSP-7 paralogs in the Thai clinical setting, to pinpoint the optimal PvMSP-7 antigen for malaria vaccine development. The conclusion of the thesis is that, of the 13 PvMSP-7 paralogs, PvMSP-7A is the most promising malaria vaccine candidate, being least polymorphic across parasite populations, expressed throughout the bloodstream infection cycle, and containing the greatest number of immunogenic B-cell epitopes. These immunogenic epitopes may confer a two-fold advantage in eliciting immunity and by impairing host cell invasion. This thesis provides a basis for the development of PvMSP-7A as an experimental vaccine, leading to the sustainable prevention of vivax malaria across the world.

In particular, we study for driven conductors the electron current and its noise properties. We review recent corresponding theoretical descriptions which are based on Floquet theory. Alternative approaches, as well as various limiting approximation schemes are investigated and compared. The general theory is subsequently applied to different representative nanoscale devices, like the non-adiabatic pumps, molecular gates, molecular quantum ratchets, and molecular transistors. Potential applications range from molecular wires under the influence of strong laser fields to microwave-irradiated quantum dots.

Optimizing acoustical conditions for speech intelligibility in classrooms
Creators: name: Yang, Wonyoung
Publisher: name: University of British Columbia
Year: 2010

description: High speech intelligibility is imperative in classrooms where verbal communication is critical. However, the optimal acoustical conditions to achieve a high degree of speech intelligibility have previously been investigated with inconsistent results, and practical room-acoustical solutions to optimize the acoustical conditions for speech intelligibility have not been developed. This experimental study validated auralization for speech-intelligibility testing, investigated the optimal reverberation for speech intelligibility for both normal and hearing-impaired listeners using more realistic room-acoustical models, and proposed an optimal sound-control design for speech intelligibility based on the findings. The auralization technique was used to perform subjective speech-intelligibility tests. The validation study, comparing auralization results with those of real classroom speech-intelligibility tests, found that if the room to be auralized is not very absorptive or noisy, speech-intelligibility tests using auralization are valid. The speech-intelligibility tests were done in two different auralized sound fields--approximately diffuse and non-diffuse--using the Modified Rhyme Test and both normal and hearing-impaired listeners. A hybrid room-acoustical prediction program was used throughout the work, and it and a 1/8 scale-model classroom were used to evaluate the effects of ceiling barriers and reflectors. For both subject groups, in approximately diffuse sound fields, when the speech source was closer to the listener than the noise source, the optimal reverberation time was zero. When the noise source was closer to the listener than the speech source, the optimal reverberation time was 0.4s (with another peak at 0.0s) with relative output power levels of the speech and noise sources SNS = 5dB, and 0.8s with SNS = 0dB. In non-diffuse sound fields, when the noise source was between the speaker and the listener, the optimal reverberation time was 0.6s with SNS = 4dB and increased to 0.8 and 1.2s with decreased SNS = 0dB, for both normal and hearing-impaired listeners. Hearing-impaired listeners required more early energy than normal-hearing listeners. Reflective ceiling barriers and ceiling reflectors--in particular, parallel front-back rows of semi-circular reflectors--achieved the goal of decreasing reverberation with the least speech-level reduction.

description: A constraint on the tidal charge generated within a brane world is shown. Using the shadow of a rotating black hole in a brane context in order to describe the M87* parameters recently announced by the Event Horizon Telescope Collaboration, the deviation from circularity of the reported shadow produces an upper bound on the bulk's nonlocal effect, which is conceived of as a tidal charge in the four-dimensional brane induced by the five-dimensional bulk. Therefore, a deviation from circularity $\lesssim 10\%$ leads to an upper bound on the tidal charge $\lesssim 0.004M^2$.

description: The calculation on the lattice of cross--sections, form--factors and decay rates associated to phenomenologically relevant physical processes is complicated by the spatial momenta quantization rule arising from the introduction of limited box sizes in numerical simulations. A method to overcome this problem, based on the adoption of two distinct boundary conditions for two fermions species on a finite lattice, is here discussed and numerical results supporting the physical significance of this procedure are shown.

description: We address a phase estimation scheme using Gaussian states in the presence of non-Gaussian phase noise. At variance with previous analysis, we analyze situations in which the noise occurs before encoding phase information. In particular, we study how squeezing may be profitably used before or after phase diffusion. Our results show that squeezing the probe after the noise greatly enhances the sensitivity of the estimation scheme, as witnessed by the increase of the quantum Fisher information. We then consider a realistic setup where homodyne detection is employed at the measurement stage, and address its optimality as well as its performance in the two different scenarios.

title: Variant Surface Glycoprotein Diversity in African Trypanosomes
Creators: name: Silva Pereira, S
Publisher: name: University of Liverpool Repository
Year: 2018

description: African trypanosomes are vector-borne haemoparasites that cause animal and human African trypanosomiasis. Survival in the mammal host is mediated by antigenic variation, an immune evasion mechanism based on the sequential replacement of the Variant Surface Glycoprotein (VSG) coat that covers the parasite surface. As the main factors in the host-trypanosome interaction, VSG expression and structure has been extensively studied in Trypanosoma brucei. Since trypanosome genomes contain hundreds of highly dynamic VSG genes, studies of VSG diversity are challenging and have been limited to reference strains. However, we expect VSG diversity to be vitally important to disease, both during individual infections and across parasite populations. This thesis examines VSG sequence diversity within and between trypanosome populations to produce new approaches to measuring VSG diversity and a holistic view of antigenic diversity in trypanosome genomes. In chapters two and five, I present ‘variant antigen profiling’ as a method to characterise VSG repertoires in genomic and transcriptomic data from T. congolense and T. vivax respectively. Due to species differences in VSG repertoire composition, bespoke methodologies were required. Analysing VSG diversity over space and time was a challenge to conventional techniques that can now be overcome. In chapter three, I apply variant antigen profiling to metacyclic transcriptomes to characterise T. congolense metacyclic VSG expression in the tsetse fly. This revealed that specific phylotypes might be preferentially expressed in infective, metacyclic-stage parasites, which can be taken forward in field experiments. In chapter four I present a description of putative T. congolense expression sites, which are compared to T. brucei. In chapter six, I present a comparative analysis of the balance of evolutionary forces affecting molecular evolution of VSGs in T. brucei, T. congolense, and T. vivax. These two chapters bring new insights into antigenic variation evolution in African trypanosomes, aiding the reconstruction of the process of host-parasite coevolution. Collectively, this work makes a substantial, original contribution to our understanding of antigenic diversity in African trypanosomes, whilst revealing the need for revisiting basic questions of the mechanisms of antigenic variation in T. congolense and T. vivax. Such projects will certainly be aided by the multiple applications of variant antigen profiling to gene expression, functional and population studies.

description: In the frame of a large project to digitize the plate archives of the Italian and Vatican Astronomical Observatories, we have already performed the digitization of all available plates of the field of the quasar 3C345. The plates, approximately 100, were taken with the three telescopes of the Asiago Observatory (122 cm, 182 cm, 67/90 cm Schmidt Telescope) in the period from 1967 to 1990. We present here essentially new data, mostly in the B band, about the variability of 3C 345 and also of other four objects (3 quasars and the active galaxy NGC 6212) in the same field, in that period. Beyond the well known 3C 345 itself, also the other three quasars show variability, with a range of 2.0 mag for Q1 and Q2, 1 mag for Q3. The low level variability detected for the nucleus of NGC 6212 is more suspicious, and should be confirmed by linear detector data.

description: Stars at the end of their lives return much of their mass back to the ISM. This process is the main source of dust in the ISM, and potentially a source of large molecules. I discuss several areas where SKA will have major impact on our understanding of the mass loss and the circumstellar processes. The resulting requirements for SKA, including frequency coverage and location, are discussed.

description: We present preliminary numerical results for the three dimensional non-compact QED with a weak four-fermion term in the lattice action. Approaches based on Schwinger-Dyson studies, arguments based on thermodynamic inequalities and numerical simulations lead to estimates of the critical number of fermion flavors (below which chiral symmetry is broken) ranging from $N_{fc}=1$ to $N_{fc}=4$. The weak four-fermion coupling provides the framework for an improved algorithm, which allows us to simulate the chiral limit of massless fermions and expose delicate effects.

Publisher: name: arXiv

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)
subject: FOS: Physical sciences

description: An explicit expression for the Kadowaki-Woods ratio in correlated metals is derived by invoking saturation of the (high-frequency) Fermi-liquid scattering rate at the Mott-Ioffe-Regel limit. Significant deviations observed in a number of oxides are quantitatively explained due to variations in carrier density, dimensionality, unit cell volume and the number of individual sheets in the Brillouin zone. A generic re-scaling of the original Kadowaki-Woods plot is also presented.

description: We performed time-series photometry of the PG1159-type star HE 1429-1209, which was recently discovered in the ESO SPY survey. We show that the star is a low-amplitude (about 0.05 mag) non-radial g-mode pulsator with a period of 919s. HE 1429-1209 is among the hottest known post-AGB stars (Teff=160000 K) and, together with the known pulsator RX J2117.1+3412, it defines empirically the blue edge of the GW Vir instability strip in the HRD at high luminosities.

description: We observe field emission from an isolated nano-machined gold island. The island is able to mechanically oscillate between two facing electrodes, which provide recharging and detection of the emission current. We are able to trace and reproduce the transition from current flow through a rectangular tunneling barrier to the regime of field emission. A theoretical model via a master-equation reproduces the experimental data and shows deviation from the Fowler-Nordheim description due to the island's electric isolation.

description: Nonlinear metasurfaces that dynamically manipulate the phase of a passing light beam are of interest for a wide range of applications. The controlled operation of such devices requires accurate measurements of the optical transmission phase in both the linear and nonlinear regime, an experimentally challenging task. In this paper we show that this phase information can be extracted directly from simple transmission measurements, using a Hilbert transform approach, removing the need for complicated, interferometric experimental set-ups, and enabling direct measurements of the phase in conditions not suitable for other traditional approaches, such Z-scan measurements.

Neo-liberal eugenics? : prenatal testing and the "insourcing" of biopolitics
Creators: name: Trawick, Richard Jonathan
Publisher: name: University of British Columbia
Year: 2010

description: This essay seeks to address some of the social concerns surrounding the practice of prenatal testing in a preliminary fashion, through a review of the existing literature and research on the topic. The focus is placed on a discussion of the claims that prenatal testing constitutes a new form of eugenics in that it is primarily concerned with the diagnosis and therapeutic abortion of fetuses that have disabling, but not imminently life-threatening conditions, and a theoretical contextualization of how prenatal testing represents a larger shift in contemporary governance of health from the state as biopolitician to the individual as biopolitician. The essay begins with a summary of prenatal testing practices and terminology, followed by a brief history of eugenics, human genetics and genetic counselling. Next, an assessment of prenatal testing and the operation of biopolitics is made followed by a discussion of how prenatal testing exposes the limits of Foucault’s concept of biopolitics. Nikolas Rose’s reconceptualization of biopolitics as riskpolitics, molecularpolitics and ethopolitics under the prevailing ideology of neo-liberalism is then used to frame the new operation of biopower. Finally, the arguments for and against the characterization of prenatal testing as a eugenic practice are examined followed by a discussion of the concerns that surround this practice. This essay concludes that a clear historical lineage can be traced between contemporary prenatal testing and previous eugenic movements and that prenatal testing could be constituted as eugenic in that it is leading to a significant reduction in the number of children born with certain disabling conditions. However, the terminology of eugenics draws attention away from the ultimate discussion of whether or not this technology is discriminatory and how might the implicit forms of discrimination be rectified. A number of specific and realistic recommendations for doing this are suggested.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Topological polarization, dual invariants, and surface flat band in crystalline insulators

description: We describe a three-dimensional crystalline topological insulator (TI) phase of matter that exhibits spontaneous polarization. This polarization results from the presence of (approximately) flat bands on the surface of such TIs. These flat bands are a consequence of the bulk-boundary correspondence of polarized topological media, and contrary to related nodal line semimetal phases also containing surface flat bands, they span the entire surface Brillouin zone. We also present an example Hamiltonian exhibiting a Lifshitz transition from the nodal line phase to the TI phase with polarization. Utilizing elasticity tetrads, we show a complete classification of 3D crystalline TI phases and invariants. The phase with polarization naturally arises from this classification as a dual to the previously better-known 3D TI phase exhibiting quantum (spin) Hall effect. Besides polarization, another implication of the large surface flat band is the susceptibility to interaction effects such as superconductivity: the mean-field critical temperature is proportional to the size of the flat bands, and this type of systems may hence exhibit superconductivity with a very high critical temperature.

description: The role of gradient dependent constitutive spaces is investigated on the example of Extended Thermodynamics of rigid heat conductors. Different levels of nonlocality are developed and the different versions of extended thermodynamics are classified. The local form of the entropy density plays a crucial role in the investigations. The entropy inequality is solved under suitable constitutive assumptions. Balance form of evolution equations is obtained in special cases. Closure relations are derived on a phenomenological level.

description: The classification of supernovae (SNe) and its impact on our understanding of the explosion physics and progenitors have traditionally been based on the presence or absence of certain spectral features. However, current and upcoming wide-field time-domain surveys have increased the transient discovery rate far beyond our capacity to obtain even a single spectrum of each new event. We must therefore rely heavily on photometric classification, connecting SN light curves back to their spectroscopically defined classes. Here we present Superphot, an open-source Python implementation of the machine-learning classification algorithm of Villar et al., and apply it to 2315 previously unclassified transients from the Pan-STARRS1 Medium Deep Survey for which we obtained spectroscopic host-galaxy redshifts. Our classifier achieves an overall accuracy of 82%, with completenesses and purities of >80% for the best classes (SNe Ia and superluminous SNe). For the worst performing SN class (SNe Ibc), the completeness and purity fall to 37% and 21%, respectively. Our classifier provides 1257 newly classified SNe Ia, 521 SNe II, 298 SNe Ibc, 181 SNe IIn, and 58 SLSNe. These are among the largest uniformly observed samples of SNe available in the literature and will enable a wide range of statistical studies of each class.

description: It is proved that the only additive and isotropic information measure that can depend on the probability distribution and also on its first derivative is a linear combination of the Boltzmann-Gibbs-Shannon and Fisher information measures. Power law equilibrium distributions are found as a result of the interaction of the two terms. The case of second order derivative dependence is investigated and a corresponding additive information measure is given.
