description: We study the evolution of the colour-magnitude relation for galaxies in the VIMOS Public Extragalactic Redshift Survey (VIPERS) by introducing the concept of the bright edge, and use this to derive constraints on the quenching of star formation activity in galaxies over the redshift range $0.5 < z < 1.1$. The bright-edge of the colour-magnitude diagram evolves with little dependence on galaxy colour, and therefore on the amount of star formation taking place in bright galaxies. We modelled this evolution with delayed exponential star formation histories (SFHs), to better understand the time-scale of the turn-off in star formation activity. We show that using SFHs without quenching, the transition from the blue cloud to the red sequence is too slow. This indicates that a scenario purely driven by the consumption of the gas inside each galaxy does not reproduce the observed evolution of the colour-magnitude bright edge. Among the quenching scenarios explored, the one that best matches the observations assumes that galaxies stop their star formation at a randomly selected time with a uniform distribution up to $2.5$ Gyr. We argue that quenching is required over a wide range of stellar masses. Qualitatively similar evolution of the bright edge is found in the predictions of a semi-analytical galaxy formation model, but quantitatively there are marked differences with the observations. This illustrates the utility of the bright edge as a test of galaxy formation models. The evolution changes and no longer matches the observed trend if feedback from heating by active galactic nuclei is turned off.

description: There is an increasing interest in microRNAs (miRNAs) as they are of utmost importance in gene regulation at the posttranscriptional level. Sex-related susceptibility for non-communicable diseases later in life could originate in early life. Until now, no data on sex-specific miRNA expression are available for the placenta. Therefore, we investigated the difference by sex of newborn’s miRNA expression in human placental tissue. Within the ENVIRONAGE birth cohort, miRNA and mRNA expression profiling was performed in 60 placentae (50% boys) using Agilent (8 × 60 K) microarrays. The distribution of chromosome locations was studied and pathway analysis of the identified sex-specific miRNAs in the placenta was carried out. Of the total 2558 miRNAs on the array, 597 miRNAs were expressed in over 70% of the samples and were included for further analyses. A total of 142 miRNAs were significantly (FDR<0.05) associated with the newborn’s sex. In newborn girls, 76 miRNAs had higher expression (hsa-miR-361-5p as most significant) and 66 miRNAs had lower expression (hsa-miR-4646-5p as most significant) than in newborn boys. In the same study population, placental differentially expressed genes by sex were also identified using a whole genome approach. The placental gene expression revealed 27 differentially expressed genes by comparing girls to boys. Ultimately, we studied the miRNA-RNA interactome and identified 14 miRNA–mRNA interactions as sex-specific. Sex differences in placental m(i)RNA expression may reveal sex-specific patterns already present during pregnancy, which may influence physiological conditions in early or later life. These molecular processes might play a role in sex-specific disease susceptibility in later life.

description: The fermion doubling theorem plays a pivotal role in Hermitian topological materials. It states, for example, that Weyl points must come in pairs in three-dimensional semimetals. Here, we present an extension of the doubling theorem to non-Hermitian lattice Hamiltonians. We focus on two-dimensional non-Hermitian systems without any symmetry constraints, which can host two different types of topological point nodes, namely, (i) Fermi points and (ii) exceptional points. We show that these two types of protected point nodes obey doubling theorems, which require that the point nodes come in pairs. To prove the doubling theorem for exceptional points, we introduce a generalized winding number invariant, which we call the discriminant number. Importantly, this invariant is applicable to any two-dimensional non-Hermitian Hamiltonian with exceptional points of arbitrary order, and moreover can also be used to characterize non-defective degeneracy points. Furthermore, we show that a surface of a three-dimensional system can violate the non-Hermitian doubling theorems, which implies unusual bulk physics.

description: Thorough control of the optical mode of a single photon is essential for quantum information applications. We present a comprehensive experimental and theoretical study of a light-matter interface based on cavity quantum electrodynamics. We identify key parameters like the phases of the involved light fields and demonstrate absolute, flexible, and accurate control of the time-dependent complex-valued wave function of a single photon over several orders of magnitude. This capability will be an important tool for the development of distributed quantum systems with multiple components that interact via photons.

description: Consumer preferences for labeled products are often assumed to be exogenous to the presence of labels. However, the label itself (and not the information on the label) can be interpreted as a noisy warning signal. We measure the impact of “contains” labels and additional information about the labeled ingredients, treating preferences for labeled characteristics as endogenous. We find that for organic-food shoppers, the “contains” label absent additional information serves as a noisy warning signal leading them to overestimate the riskiness of consuming the product. Providing additional information mitigates the large negative signaling effect of the label.
A locally compact quantum group analogue of the normalizer of SU(1,1) in SL(2,C)

description: S.L. Woronowicz proved in 1991 that quantum SU(1,1) does not exist as a locally compact quantum group. Results by L.I. Korogodsky in 1994 and more recently by Woronowicz gave strong indications that the normalizer N of SU(1,1) in SL(2,C) is a much better quantization candidate than SU(1,1) itself. In this paper we show that this is indeed the case by constructing N_q, a new example of a unimodular locally compact quantum group (depending on a parameter q) that is a deformation of N. After defining the underlying von Neumann algebra of N_q we use a certain class of q-hypergeometric functions and their orthogonality relations to construct the comultiplication. The coassociativity of this comultiplication is the hardest result to establish. We define the Haar weight and obtain simple formulas for the antipode and its polar decomposition. As a final result we produce the underlying C*-algebra of N_q. The proofs of all these results depend on various properties of q-hypergeometric 1\phi1 functions.

description: Cerebral contusions that result from brain trauma have the propensity to enlarge over the days following injury, including extension of the haemorrhage core and swelling of the surrounding peri-contusional brain. This secondary injury increases the likelihood of death and severe disabil- ity, and interventions to prevent or limit contusion progression may improve clinical outcomes. In preclinical studies a number of pathophysiological process have been identified that contribute to brain oedema including blood brain barrier (BBB) disruption, neuroinflammation, and cerebral metabolic dysfunction. This work has set out to measure and quantify contusion progression in TBI patients, characterise BBB permeability with computed tomography imaging, and identify key mediators of this process using intracerebral microdialysis. • Study I: A robust and effective stereological method for measuring the volume of brain lesions was validated and applied to a cohort of TBI patients to examine the temporal course of contusion progression. Intracranial pressure and brain lactate/pyruvate ratio were found to be associated with the magnitude of contusion expansion. • Study II: Dynamic contrast enhanced computed tomography (DCE-CT) was applied in pa- tients with brain contusions to quantify BBB permeability. The imaging showed profound reduction in cerebral blood flow associated with contusions but did not show evidence of contrast extravasation or BBB permeability. • Study III: Paired microdialysis catheters, one inserted in proximity to a contusion and an- other in non-injured brain, were used to characterise the peri-contusional inflammatory response with a multiplex assay of 42 cytokines, chemokines, and growth factors. Peri- contusional tissue was found to exhibit an early pro-inflammatory signature. • Study IV: A paired microdialysis study of pericontusional expression of matrix metalloproteinases (MMP). Specific increase in the expression of MMP-9 was identified in pericontusional brain. • Study V: Nitric oxide (NOx) concentrations were assayed in pericontusional and uninjured brain with paired microdialysis. NOx levels were lower in pericontusional brain and exhibited significant correlations with brain glucose, pyruvate, and lactate. • Study VI: Microdialysis data from 619 TBI patients with collated to explore the physiological correlates of deranged metabolism and elevated LPR. Cerebral glucose was found to a key determinant of LPR. The implications of these findings in the context of existing knowledge of BBB permeability, in- flammation, and cerebral metabolism in TBI are discussed. Future investigations to clarify the mechanisms highlighted, and potential therapeutic studies directed at reducing contusion pro- gression and brain oedema are suggested.

description: Cell-fate networks are traditionally studied within the framework of gene regulatory networks. This paradigm considers only interactions of genes through expressed transcription factors and does not incorporate chromatin modification processes. This paper introduces a mathematical model that seamlessly combines gene regulatory networks and DNA methylation (DNAm), with the goal of quantitatively characterizing the contribution of epigenetic regulation to gene silencing. The ‘Basin of Attraction percentage’ is introduced as a metric to quantify gene silencing abilities. As a case study, a computational and theoretical analysis is carried out for a model of the pluripotent stem cell circuit as well as a simplified self-activating gene model. The results confirm that the methodology quantitatively captures the key role that DNAm plays in enhancing the stability of the silenced gene state.

For $n=d=1$ we can handle all polynomials. In higher dimensions, we pose restrictions on the admissible polynomial mappings stemming from a combination of interacting geometric, analytic and number-theoretic obstacles.

description: With the growing concerns over global warming and depleting oil reserves, full and hybrid electric vehicles (EVs) are gaining significant attention from commercial bodies as well as government policymakers. Considering the high cost and range anxiety of full EVs, hybrid EVs are expected to be the immediate solution. The electric drive train of the hybrid vehicle needs to have four main functions, high torque low-speed motoring for engine starting,low torque high speed generating for charging the onboard battery as the vehicle alternator, medium torque medium speed motoring for torque boost, and medium torque medium speed generating for regenerative braking. Two electric machine drives are normally required to meet the above requirements, resulting in a complex system and higher cost. In this thesis, a novel induction machine drive, reconfigurable induction machine drive (RIMD) is proposed to achieve a modified torque-speed envelope, so the drive train of hybrid EVs can be replaced by one single machine drive. The reconfigurable induction machine drive is based on the principle of pole phase modulation. A novel concept of independent phase belt controlled pole-phase modulation is developed. The proposed pole-phase modulation technique offers higher reconfigurability compared to the previously reported literature. As an example, a toroidally wound machine with 36 stator slots can be reconfigured to 2/4/6/8/10 pole operation by using a 12-phase inverter. The proposed concept is analysed by using Finite Element Analysis (FEA) method and the equivalent circuit and parameters of the reconfigurable induction machine are obtained. To validate the proposed machine, a scaled-down 1.5 kW prototype has been developed which is capable of 2/4/6/8/10 pole operation. A 12-phase inverter has been developed as well to drive the machine. Results from open and short circuit tests have validated the design and equivalent circuit model of the machine. A circulating power test bench has been developed. The torque-speed characteristics of the developed machine have been obtained from the test bench. Finally, a dynamic model of the proposed RIMD has been developed based on the d-q model theory. The model has been then used to develop an online pole transition control scheme, which ensures there is no significant oscillation in speed and current. The scheme allows online pole transition in only 0.1 s. The dynamic model along with with the proposed control scheme has been simulated in Matlab – Simulink platform. Finally the online pole changing control scheme has been implemented in the hardware and the experimental results are reported.

description: We explore how market power in a complementary input sector compares to that in a downstream sector for producer and consumer welfare. We develop a model of a homogeneous product market encompassing bilateral and complementary relationships. Our main finding is that market power exercised by the supplier of a complementary input generates greater negative welfare effects than the same level of market power exercised by downstream firms. We provide a discussion of the implications of the results for policy in the context of current problems in the Canadian grain-handling and transportation system.

This study uses transaction data from Iowa preconditioned and regular feeder-calf auction sales to quantify the impact of a wide variety of factors, several of which have not been used in previous studies on feeder-calf prices. Notably, market premiums for preconditioned sales versus regular sales, feedlot capacity utilization, and seller reputation are found to be significant factors affecting feeder-calf prices. Estimated coefficients are then used to predict prices to demonstrate how this information can be used in making management and marketing decisions.

description: Accurate and consistent mental interpretation of fluoroscopy to determine the position and orientation of acetabular bone fragments in 3D space is difficult. We propose a computer assisted approach that uses a single fluoroscopic view and quickly reports the pose of an acetabular fragment without any user input or initialization. Intraoperatively, but prior to any osteotomies, two constellations of metallic ball-bearings (BBs) are injected into the wing of a patient's ilium and lateral superior pubic ramus. One constellation is located on the expected acetabular fragment, and the other is located on the remaining, larger, pelvis fragment. The 3D locations of each BB are reconstructed using three fluoroscopic views and 2D/3D registrations to a preoperative CT scan of the pelvis. The relative pose of the fragment is established by estimating the movement of the two BB constellations using a single fluoroscopic view taken after osteotomy and fragment relocation. BB detection and inter-view correspondences are automatically computed throughout the processing pipeline. The proposed method was evaluated on a multitude of fluoroscopic images collected from six cadaveric surgeries performed bilaterally on three specimens. Mean fragment rotation error was 2.4 +/- 1.0 degrees, mean translation error was 2.1 +/- 0.6 mm, and mean 3D lateral center edge angle error was 1.0 +/- 0.5 degrees. The average runtime of the single-view pose estimation was 0.7 +/- 0.2 seconds. The proposed method demonstrates accuracy similar to other state of the art systems which require optical tracking systems or multiple-view 2D/3D registrations with manual input. The errors reported on fragment poses and lateral center edge angles are within the margins required for accurate intraoperative evaluation of femoral head coverage.

description: Maternal stress is associated with adverse child health. Breast milk microRNAs encapsulated in extracellular vesicles (EVs) are involved in mother-infant biochemical communication during early-life programming. We leverage the PRogramming of Intergenerational Stress Mechanisms (PRISM) pregnancy cohort to investigate associations between maternal stress and breast milk EV-microRNAs. Lifetime stress and negative life events (NLEs) during pregnancy were assessed using the Life Stressor Checklist-Revised (LSCR) and the Crisis in Family Systems-Revised surveys, respectively. RNA was extracted from breast milk EVs (N = 80; collected 6.1 ± 5.9 weeks postnatally), and microRNAs were profiled using the TaqMan OpenArray Human miRNA panel. Associations between stress scores and detection (yes/no) of 173 microRNAs identified in 20–80% of samples were assessed using logistic regression; associations with expression levels of 205 EV-microRNAs identified in >50% of samples were assessed using linear regression. In adjusted models, detection of 60 and 44 EV-microRNAs was associated with higher LSCR and NLE scores, respectively (p priori criteria of p Bregression|>0.2. Enriched KEGG pathways for microRNAs associated with stress scores included fatty acid metabolism and the Hippo signaling pathway. Maternal lifetime stress and NLEs during pregnancy were both associated with detection and expression level of breast milk EV-microRNAs, although associations with microRNA profiles differed between stress measures. Further research is needed to identify biological pathways impacted by associated microRNAs and investigate relationships with child health outcomes.

description: We propose a model that elucidates the two channels through which alternative marketing arrangements affect spot price in livestock markets. The direct effect works through their effect on demand and supply. The indirect effect works through spot price volatility, which has been ignored in the literature. We then estimate a dynamic model with data from the U.S. hog market to test our model implications and quantify the two effects. We find increases in the use of AMAs increase spot price volatility and decrease spot price level. The short-run effects are small but the long-run effects are nontrivial.

subject: Jump Diffusion

description: An anchoring-adjusted option pricing model is developed in which the expected return of the underlying stock is used as a starting point that gets adjusted upwards to form expectations about corresponding call option returns. Anchoring bias implies that such adjustments are insufficient. In continuous time, the anchoring price always lies within the bounds implied by expected utility maximization when there are proportional transaction costs. Hence, an expected utility maximizer may not gain utility by trading against the anchoring prone investors. The anchoring model is consistent with key features in option prices such as implied volatility skew, superior historical performance of covered call writing, inferior performance of zero-beta straddles, smaller than expected call option returns, and large magnitude negative put returns. The model is also consistent with the puzzling patterns in leverage adjusted option returns, and extends easily to jump-diffusion and stochastic-volatility approaches.

description: In this contribution we review the large body of work carried out over the past two decades to probe the dark matter in the local universe using redshift survey and peculiar velocity data. While redshift surveys have evolved rapidly over the years, gathering suitable peculiar velocity data and understanding the short-comings of different analyses have proven to be a difficult task. These difficulties have led to conflicting results which have casted some doubts on the usefulness of cosmic flows to constrain cosmological models. Recently, however, a consistent picture seems to be finally emerging with various methods of analyses applied to different data sets yielding concordant results. These favor a low-density universe, with constraints which are in good agreement with those obtained from LSS, high-redshift supernovae and CMB studies.

Turbulent entrainment in flows induced by distributed buoyancy sources

description: Free shear and wall-bounded buoyancy-driven turbulent flows occur in both natural environments and industrial situations. In this thesis, to better understand the entrainment process within these flows, experiments and theory have been used to investigate point and distributed buoyancy sources and, in particular, the effect of a bounding vertical wall on these flows. A free shear flow was first investigated by performing velocity and scalar edge measurements on an axisymmetric plume created by a continuous point source release of buoyancy. By conditionally sampling the velocity measurements based on the presence of both eddies and plume fluid, engulfment, whereby large pockets of ambient are engulfed in to the plume, was shown to be a dominant turbulent entrainment process. To isolate the effect of a wall on a turbulent buoyancy-driven flow, a line plume distant from all vertical boundaries and a wall plume, adjacent to a vertical wall were also studied. Simultaneous velocity and buoyancy field measurements were performed and a reduction in the net entrainment, and entrainment coefficient, for a wall plume were found. This reduction was investigated by considering an energy decomposition of the entrainment coefficient where the relative contributions of turbulent production, buoyancy and viscous terms were calculated. The reduced entrainment was also investigated by considering the statistics of the turbulent interface. Finally, simultaneous velocity and buoyancy field measurements on a vertically distributed buoyant plume were performed by forcing relatively dense fluid through a very low porosity plate. A reduced entrainment coefficient, compared to that of a wall plume, was observed. In order to model the ventilation of a room with a heated or cooled wall the flow was then enclosed within a mechanically ventilated model room. The evolving and steady-state ambient stratification was measured using dye-attenuation with an LED-light bank for varying buoyancy fluxes and ventilation flow rates.

description: Being a fundamental component in training and inference, data processing has not been systematically considered in human pose estimation community, to the best of our knowledge. In this paper, we focus on this problem and find that the devil of human pose estimation evolution is in the biased data processing. Specifically, by investigating the standard data processing in state-of-the-art approaches mainly including coordinate system transformation and keypoint format transformation (i.e., encoding and decoding), we find that the results obtained by common flipping strategy are unaligned with the original ones in inference. Moreover, there is a statistical error in some keypoint format transformation methods. Two problems couple together, significantly degrade the pose estimation performance and thus lay a trap for the research community. This trap has given bone to many suboptimal remedies, which are always unreported, confusing but influential. By causing failure in reproduction and unfair in comparison, the unreported remedies seriously impedes the technological development. To tackle this dilemma from the source, we propose Unbiased Data Processing (UDP) consist of two technique aspect for the two aforementioned problems respectively (i.e., unbiased coordinate system transformation and unbiased keypoint format transformation). As a model-agnostic approach and a superior solution, UDP successfully pushes the performance boundary of human pose estimation and offers a higher and more reliable baseline for research community.

description: In this paper we consider the possibility of measuring the corrections induced by the square of the parameter a_g of the Kerr metric to the general relativistic deflection of electromagnetic waves and time delay in an Earth based experiment. It turns out that, while at astronomical scale the well known gravitoelectric effects are far larger than the gravitomagnetic ones, at laboratory scale the situation is reversed: the gravitomagnetic effects exceed definitely the gravitoelectric ones which are totally negligible. By using a small rapidly rotating sphere as gravitating source on the Earth the deflection of a grazing light ray amounts to 10^{-13} rad and the time delay is proportional to 10^{-23} s. These figures are determined by the upper limit in the attainable values of a_g due to the need of preventing the body from exploding under the action of the centrifugal forces. Possible criticisms to the use of the Kerr metric at a_g^2 level are discussed.

description: Maternal stress is associated with adverse child health. Breast milk microRNAs encapsulated in extracellular vesicles (EVs) are involved in mother-infant biochemical communication during early-life programming. We leverage the PRogramming of Intergenerational Stress Mechanisms (PRISM) pregnancy cohort to investigate associations between maternal stress and breast milk EV-microRNAs. Lifetime stress and negative life events (NLEs) in the past 6 months during pregnancy were assessed using the Life Stressor Checklist-Revised (LSCR) and the Crisis in Family Systems-Revised surveys, respectively. Breastmilk was collected 6.1±5.9 weeks postnatally (N=80), RNA was extracted from isolated EVs, and microRNAs were profiled using the TaqMan OpenArray Human miRNA panel. Associations between stress scores and detection (yes/no) of 173 microRNAs identified in 20-80% of samples were assessed using logistic regression; associations with expression levels of 205 EV-microRNA identified in >50% of samples were assessed using linear regression. In adjusted models, detection of 60 and 44 EV-microRNAs was associated with increased LSCR and higher NLE scores, respectively (p<0.05). Expression level of 8 and 17 EV-microRNAs was associated with LSCR and NLE scores, respectively, at our a priori criteria of p<0.05 and |Bregression |>0.2. Enriched KEGG pathways for microRNAs associated with stress scores included fatty acid metabolism and the Hippo signaling pathway. Maternal lifetime stress and NLEs during pregnancy were both associated with detection and expression level of breast milk EV-microRNAs, although associations with microRNA profiles differed between stress measures. Further research is needed to identify biological pathways impacted by associated microRNAs and investigate relationships with child health outcomes.

description: Much of the scholarship on refugee camps has focused on the spatial politics of such sites, but only a small number of scholars has primarily examined the temporal dimension. While the literature has acknowledged the complex nature of time in these humanitarian spaces, time itself has not often been used as an analytical tool through which to understand the power dynamics at the center of refugee camp operation. This dissertation contributes to this area of literature by interrogating the relationship between time and power as it manifests through daily lived realities in Azraq refugee camp in Jordan. Based on 14 months of ethnographic fieldwork, this dissertation seeks to complicate perceptions of Azraq as the ‘ideal’ refugee camp through an investigation of its particular politics of time, analyzing perspectives of both refugees and aid workers. I call on literature on emergency, bureaucracy, and humanitarian politics in order to examine how these power structures have established a monopoly over time within the camp’s borders. I analyze the role of street-level aid workers within Azraq’s bureaucracy as being both shapers of policy but also subject to the power system and its particular temporalities. I explore how refugees then navigate this system, both in the day-to-day and over years, by evaluating various layers of waiting as they affect refugee perceptions of time in the camp – not only the present, but the past, near future, and far future. By focusing on time in particular, this dissertation reveals a significant temporal dimension of refugee governance in Azraq, and in Jordan more generally. I argue that the camp operates as a ‘nine-to-five’ emergency through which mundane bureaucratic procedures serve to sustain a power system that manipulates refugees’ time. The camp administration limits refugees’ capacity to enhance the camp environment as it seeks to preserve the camp as new and refugees as vulnerable and thus under control. Refugees are socialized by this power politics to endure a cynical wait – both for services and for the return – without expectations for a better outcome; that is, refugees wait merely as if they believe a meaningful future is possible. I argue that, far from an ‘ideal’ camp, Azraq and its politics of time constitute a cruel reality in which a power system meant to aid refugees is experienced as one that suppresses, foreclosing futures that it is supposed to preserve. This fits within a Jordanian project of containment and isolation of Syrian refugees, a project both spatial and – equally as important – temporal in nature.

description: Effective hadron models commonly require the computation of functional determinants. In the static case these are one--loop vacuum polarization energies, known as Casimir energies. In this talk I will present general methods to efficiently compute renormalized one--loop vacuum polarization energies and energy densities and apply these methods to construct soliton solutions within a variational approach. This calculational method is particularly useful to study singular limits that emerge in the discussion of the {\it classical} Casimir problem which is usually posed as the response of a fluctuating quantum field to externally imposed boundary conditions.
