description: This thesis develops a narrative for the horses and mules of the Canadian artillery units and ammunition columns, while consequently expanding that of the soldiers serving alongside them. Carrying out mounted, draught, and pack work, these animals played an invaluable role in military operations and greatly impacted daily life. Immense effort was made to preserve the wellbeing of the horses and mules, although casualties were considered inevitable. The evolution of the acquisition, training, and transport practices of these animals and men is examined. This is followed by a general analysis of the labour performed and the working conditions, with specific battles given as case studies. The daily care that went into the horses and mules and the relationship between man and animal is also addressed. Finally, the negligible impact of mechanization is discussed.

Learning as laowai : race, social positioning, and Chinese language acquisition in China
Creators: name: Ilnyckyj, Roma Areta
Publisher: name: University of British Columbia
Year: 2010

description: Due to China’s increasing economic and political power, interest in learning Chinese as an Additional Language (CAL) is growing rapidly around the world. Large numbers of learners with no historical or cultural ties to China are undertaking the study of Mandarin, often for professional or economic gain. Research in the field of CAL has traditionally been driven by cognitive considerations, and has only recently begun to examine social and cultural factors that influence the learning of Chinese. In particular, the relationships between language acquisition and social identity categories such as race, gender, and class have only begun to be investigated. This interview-based multiple case study explored the relationship between racial identity and language acquisition in China. Interviews were conducted with five adult, White learners of Mandarin who had previously studied or worked in China. The study found that participants were sensitive to their privileged position in the Chinese context, and worked to construct the identity of the conscientious sojourner in order to address this privilege. Simultaneously, their racialized identity as White sojourners caused their learning of Chinese to function as discordant knowledge, or knowledge that they were not, for social and cultural reasons, expected to possess. This discordance of their knowledge often allowed participants greater power or access to particular target communities. This study provides insight into the experiences of a particular set of White learners of Chinese, offering a starting point for further research into the relationship between racial identity and Chinese language acquisition.

description: We present measurements of ionospheric Poynting flux using new data from the EFI (Electric Field Instruments) and magnetometers on the ESA Swarm spacecraft. Global maps of the ionospheric Poynting flux are provided as a function of interplanetary magnetic field (IMF) conditions and geomagnetic activity levels. On average, it is found that the ionospheric Poynting flux is directed downwards into the Earth, indicating that it acts to dissipate elec- tromagnetic energy from the Sun-Magnetosphere system. A preliminary analysis indicates that the total Poynting flux into the ionosphere depends on IMF Bz. It is found that the total dissipation in the northern hemisphere exceeds that which occurs in the southern hemisphere by approximately one order of magnitude. This implies that electrical dissipation structures in the ionosphere are acting as potential, rather than current driven systems.

On the equivalence between standard and sequentially ordered hidden Markov models

description: Chopin (2007) introduced a sequentially ordered hidden Markov model, for which states are ordered according to their order of appearance, and claimed that such a model is a re-parametrisation of a standard Markov model. This note gives a formal proof that this equivalence holds in Bayesian terms, as both formulations generate equivalent posterior distributions, but does not hold in Frequentist terms, as both formulations generate incompatible likelihood functions. Perhaps surprisingly, this shows that Bayesian re-parametrisation and Frequentist re-parametrisation are not identical concepts.
Prenatal Risk Factors for Childhood Obesity: A Meta-Analysis

Subjects: subject: Educational Psychology

subject: risk factor

description: The purpose of this study was to determine the significance of two prenatal risk factors for the development of childhood overweight and/or obesity: maternal smoking and family history of obesity. Accordingly, a systematic literature review of English-language studies published from 1980 to 2012 using the following data bases: MEDLINE, PsychINFO, Cochrane Database of Systematic Reviews, and Dissertation Abstracts International was conducted. The following terms were used in the search: pregnancy, overweight, obesity, smoking, family history, parents, childhood, risk factors. Eighteen studies of maternal smoking during pregnancy and 11 studies of family history and obesity conducted in Europe, Asia, North America, and South America met the inclusion criteria. A meta-analysis of these studies indicated that maternal smoking during pregnancy is a significant risk factor for overweight and obesity; mothers who smoke during pregnancy are at a greater risk for developing obesity or overweight; the quantity of cigarettes consumed by the mother during pregnancy influenced the odds of offspring overweight and/or obesity; family history of obesity is a significant risk factor of overweight and /or obesity in offspring; risk for offspring overweight and/or obesity associated with family history varies depending of the family members included in the analysis; and when family history of obesity is present, the offspring are at greater risk for developing obesity or overweight. In addition, the results from moderator analyses suggest that part of the heterogeneity discovered between the studies can be explained by the region of world that the study occurred in and the age of the child at the time of weight assessment. The strengths as well as limitations of the study are discussed, along with directions for future research, practical implications, and the relationship of the research findings to the field of school psychology.
Counting statistics of heat transport in harmonic junctions -- transient and steady states

description: We study the statistics of heat transferred in a given time interval $t_M$, through a finite harmonic chain, called the center $(C)$, which is connected with two heat baths, the left $(L)$ and the right $(R)$, that are maintained at two different temperatures. The center atoms are driven by an external time-dependent force. We calculate the cumulant generating function (CGF) for the heat transferred out of the left lead, $Q_L$, based on two-time measurement concept and using nonequilibrium Green's function (NEGF) method. The CGF can be concisely expressed in terms of Green's functions of the center and an argument-shifted self-energy of the lead. The expression of CGF is valid in both transient and steady state regimes. We consider three different initial conditions for the density operator and show numerically, for one-dimensional (1D) linear chains, how transient behavior differs from each other but finally approaches the same steady state, independent of the initial distributions. We also derive the CGF for the joint probability distribution $P(Q_L,Q_R)$, and discuss the correlations between $Q_L$ and $Q_R$. We calculate the total entropy flow to the reservoirs. In the steady state we explicitly show that the CGF obeys steady state fluctuation theorem (SSFT). Classical results are obtained by taking $\hbar \to 0$. The method is also applied to the counting of the electron number and electron energy, for which the associated self-energy is obtained from the usual lead self-energy by multiplying a phase or shifting the contour time, respectively.

description: Studying mobilities means paying attention to practices, subjectivities, materialities, sociospatially co-constituted spaces, and the complex social, political, and economic milieus in which planners, policy makers, and mobile subjects operate. When the complexities and interplays of these aspects of mobility are considered together, we can describe regimes of mobility. This dissertation focuses on a specific form of mobility: velomobility (mobility by bicycle). It presents a comparative analysis of the regimes of velomobility in two cities: Calgary, Canada, and Amsterdam, Netherlands. It draws from a wide range of evidence, including 102 semi-structured interviews conducted with cyclists, 24 interviews conducted with policy makers, document analysis (including a visual content and thematic analysis of print advertisements), and ethnographic research (including ethnographic photography). By comparing and contrasting these two regimes of velomobility, this dissertation seeks to de-naturalize velomobility by highlighting the ways that politics and policies affect mobile subjectivities and associated practices by enabling or constraining urban forms, by influencing the design and development of transportation infrastructure, and by encouraging or restricting automobility. Drawing on notions of governmentality, sociospatial theory, risk, class habitus, and the performance of identity, this research project sits at the intersections of several theoretical frameworks as it explores the intersections through which cyclists move.

description: We use semiclassical methods to evaluate the spectral two-point correlation function of quantum chaotic systems with discrete geometrical symmetries. The energy spectra of these systems can be divided into subspectra that are associated to irreducible representations of the corresponding symmetry group. We show that for (spinless) time reversal invariant systems the statistics inside these subspectra depend on the type of irreducible representation. For real representations the spectral statistics agree with those of the Gaussian Orthogonal Ensemble (GOE) of Random Matrix Theory (RMT), whereas complex representations correspond to the Gaussian Unitary Ensemble (GUE). For systems without time reversal invariance all subspectra show GUE statistics. There are no correlations between non-degenerate subspectra. Our techniques generalize recent developments in the semiclassical approach to quantum chaos allowing one to obtain full agreement with the two-point correlation function predicted by RMT, including oscillatory contributions.

description: An observable on a quantum structure is any $σ$-homomorphism of quantum structures from the Borel $σ$-algebra of the real line into the quantum structure which is in our case a monotone $σ$-complete effect algebras with the Riesz Decomposition Property. We show that every observable is a smearing of a sharp observable which takes values from a Boolean $σ$-subalgebra of the effect algebra, and we prove that for every element of the effect algebra there is its spectral measure.

description: Monitoring the concentration of methane is of crucial importance for health, safety, and maintenance. NDIR spectroscopy is a widely used commercially available method of monitoring the concentration of Gases. Enhancing the sensitivity of the IR detector enhances the limit of detection of NDIR sensors. Plasmonic crystal structures have been shown to enhance the absorption of EM radiation at certain wavelengths depending on their dimensions. In this thesis, a 13 fold enhancement in the LOD of a methane NDIR gas sensor was achieved by designing a plasmonic crystal structure. The structure is a layer of gold with a two dimensional array of micro sized holes. The dimensions of the structure were optimized by COMSOL simulations to get maximum absorption at λ=7.7 µm. The structure was fabricated and the NDIR sensor was developed to experimentally show the enhancement. The experimental results showed good agreement with the simulations and achieved the expected enhancement.

description: Over the last decade, online Learning Management System (LMS) services have been utilized by many universities. Desire2Learn (D2L) is the official LMS used by the University of Calgary (U of C). Every student, teaching assistant, and faculty member has access to D2L services. This thesis presents a workload characterization study of the D2L Web site for on-campus and off-campus users based on a period of two calender years, 2015 and 2016. D2L mainly provides online learning services, delivers course content, and monitors student progress. It uses content delivery networks consisting of geographically dispersed nodes. Persistent and parallel connections are used extensively throughout D2L sessions with users. This thesis sheds light upon the usage of modern LMS services like D2L. It utilizes network-level data for an extended period of time. Our measurement results highlight the impacts of network latency on the user-perceived D2L performance at the U of C.

description: We introduce a class of compactly supported C infinite kernels (CINAPACT-splines) whose integer translates form a shift-invariant reconstruction space that can be tuned to achieve any order of accuracy. CINAPACT-splines resemble traditional B-splines in that higher orders of accuracy are achieved by successive convolutions with a B-spline of degree zero. Unlike B-splines however, the starting point for CINAPACT-splines is a compactly supported bump function that has been properly normalized so that it fulfills the partition of unity criterion. We explore the properties of CINAPACT-splines in reconstructing volumetric data sampled on regular grids. We show that CINAPACT-splines provide similar reconstruction quality and cost compared to some well-established filters, while being infinitely smooth. We further explore the advantages of our filter by implementing a curvature-based transfer function using second derivatives of the filter to demonstrate feature lines of a function. We apply the same technique using filters of smaller support and less cost.
Incorporating Asset-Building into a Shared Risk Factor Approach to School-Based Eating Disorder and Obesity Prevention

description: In response to the high prevalence of eating disorders and obesity in adolescents, researchers are increasingly recognizing the benefits of developing universal prevention programs that address risk factors relevant to both issues. Further, an exclusive emphasis on risk overlooks the strengths in adolescents’ lives, potentially undermining their capacity to overcome challenges and develop into healthy adults. The developmental assets framework, which is composed of internal and external assets that have been consistently associated with a broad range of outcomes and health behaviours, represents an optimistic vocabulary for discussing adolescent health that has been gaining momentum in the prevention literature. For the current research study, five shared risk factors (low self-esteem, body dissatisfaction, dieting, weight-related teasing, and media internalization) were targeted through a school-based eating disorder and obesity prevention program that simultaneously promoted three developmental asset areas (positive identity, positive values, and social competencies). Teacher-led lesson plans known as Body Image Kits were delivered to junior high school students as part of their physical education classes. A quasi-experimental research design was used to assess program effectiveness by examining participants’ scores on measures of risk factors and developmental assets at post-program and follow up when compared to those of a control group. Additional subgroup analyses were also conducted to assess if intervention group participants demonstrated differential program effects based on baseline levels of developmental assets. Generalized estimating equations (GEE) were used to measure between-group differences over time. Results of the analyses revealed that the intervention group experienced a short-term reduction in dieting as well as greater overall positive identity compared to the control group. No other significant group or interaction effects were found for the remaining risk factors or developmental asset areas. Findings from the subgroup analyses were mixed, indicating the need to further explore the potential utility of applying the developmental assets framework to complement eating disorder and obesity prevention. The modest program effects found in this research illuminate the practical and methodological challenges that accompany universal school-based research. The implications of these challenges for school-based eating disorder and obesity prevention, counselling psychology, and research, as well as accompanying recommendations, are discussed.

The coupling of center-of-mass and relative-motion coordinates is treated using an exact diagonalization (configuration-interaction) approach. The orthorhombic symmetry of an optical lattice with three different but orthogonal lattice vectors is explicitly considered as is the Fermionic or Bosonic symmetry in the case of indistinguishable particles.

description: There are gaps in the current literature on Generalized Linear Models (GLM) for binary outcomes with the log link. This dissertation explores a number of these gaps and presents specific results: (1) Uniqueness considerations for the Maximum Likelihood Estimate (MLE) are established from the conditions for the strict concavity of the log-likelihood. The full column rank of certain subsets of the covariate matrix is shown to be a condition for the strict concavity of the loglikelihood. (2) Conditions are established for the finiteness of components of the MLE. A method is proposed to address the possibility of non-finite components for the MLE, and it is based on determining directions of recession of the log-likelihood. In addition, it is established when the MLE will be in the interior of the parameter space and when the MLE will possibly be on a boundary of the parameter space. (3) Examples are presented of closed form expressions for the MLE. For a number of models with indicator variables and measured variables, closed form expressions for the MLE are presented. (4) There are considerations for the construction of confidence intervals when the MLE is close to a boundary of the parameter space. A new metric, called the “fraction within the parameter space”, is introduced for assessing intervals for MLEs close to a boundary. A simulation study is provided that offers support for Bootstrap Percentile Intervals having larger fractions when compared to Relative Likelihood Intervals and Normal Confidence Intervals. This dissertation continues by developing a proportional probability model using the log link for ordinal outcomes. For this model, similar results are presented for topics (1) and (3) above. In addition, there is the introduction of a score test to assess proportionality. The dissertation concludes with a discussion of future work. In particular, this discussion includes some preliminary work with the identity link GLM for binary and ordinal outcomes. Throughout this dissertation, there are many practical considerations and illustrations presented. The use of the log link and the identity link for binary and ordinal outcomes should now become a viable modeling option for researchers.

Science Diplomacy
foresight analysis

description: This study seeks to explore the possible developments facing the EU and its role of leadership in a global science diplomacy. Engaging in a foresight analysis, its aim is to provide a reflection on future scenarios and how EU action could influence and operate within them.  The emergence of a clear EU science diplomacy is faced with challenges which are both of a conceptual and material nature. On the one hand, the term remains subject to different interpretations and uses, and its value as a label for science cooperation initiatives is still unclear. On the other hand, unprecedented challenges like climate change require concerted science-based solutions. These seem increasingly harder to achieve in contexts where populist movements discredit scientific evidence as a basis for policy making or where scientific and technological progress is read in a purely competitive way. Within the EU, lack of support for further integration in domains that are not yet communitarised and distance between policy makers and the scientific community risk to nip EU science diplomacy in the bud.

description: The purpose of this research is to investigate the change in geometry of a hydraulic fracture aperture over time when cold frac fluid is injected into a hot reservoir. Secondary cracks may occur around the surface of a hydraulic fracture if there is large difference between frac fluid and the formation temperature. The study is organized as follows: 1. Literature review and development of fundamental equations (Chapter 1 & 2): Literature related to hydraulic fracture stimulation is reviewed, to support this study’s importance and explain how it will enrich the research in the field of hydraulic fracturing. Fundamental equations of flow and deformation, which form the basis of this this research, are developed. 2. Initiation and propagation of secondary cracks (Chapter 3): Using the finite element method, initiation and propagation of secondary cracks in porous media is calculated under varying combinations of pore pressure, temperature, Young’s modulus, initial effective stress, pressure and thermal diffusivity, leakoff conditions and crack spacing. The initiation time and growth of the length and width of the secondary cracks are computed. 3. Growth and decay of a hydraulic fracture (Chapter 4): Aperture formulae, based on the continuum thermo-poroelasticity for a KGD (Khristianovic-Geerstma-de Klerk) fracture model under 2D plane strain and plane stress conditions, are developed. These new, simple formulae consider the effects of poroelasticity and thermo-elasticity, as well as the distances the pressure and temperature propagate into the medium (penetration depth). The aperture formulae are validated by comparing their results with the results of the finite element method. The comparison shows that the simplified formulae provide excellent results with significant reduction in computation time. 4. Effects of secondary cracks on the aperture of hydraulic fracture (Chapter 5): This phenomenon is quite new in the hydraulic fracturing stimulation. Under given boundary conditions, secondary cracks will appear on the fracture surface and propagate into the formation. When the secondary cracks occur, fracture aperture magnitude and shape change. Therefore, the presence of secondary cracks will significantly influence the fracturing stimulation process. Discussion and recommendations for further studies are provided at the end of the dissertation in Chapter 6. The results emphasize the important role that geomechanics plays in the simulation of hydraulic fracturing.

description: We obtain a compact expression for the octagon MHV amplitude / Wilson loop at 3 loops in planar N=4 SYM and in special 2d kinematics in terms of 7 unfixed coefficients. We do this by making use of the cyclic and parity symmetry of the amplitude/Wilson loop and its behaviour in the soft/collinear limits as well as in the leading term in the expansion away from this limit. We also make a natural and quite general assumption about the functional form of the result, namely that it should consist of weight 6 polylogarithms whose symbol consists of basic cross-ratios only (and not functions thereof). We also describe the uplift of this result to 10 points.

description: The present study investigated whether naming would facilitate infants’ transfer of information from picture books to the real world. Independent groups of 18- and 21-month-olds were shown a picture book that taught them a novel label for a novel object. Infants then saw a second picture book in which an adult demonstrated how to elicit the object’s nonobvious property. Accompanying narration described the pictures using the object’s newly learned label. Infants were subsequently tested with the real-world object depicted in the book and a different-colour exemplar. Infants’ performance on the test trials was compared with that of infants in a no label condition. The odds of attempting to elicit the object’s nonobvious property with the exact object depicted in the book were almost 2.5 times greater for infants who heard the label compared to infants who did not. Naming did not predict test performance for the different-colour exemplar.

description: The recent discovery of a transiting planet around WASP-33, the misalignment of the stellar rotation axis and the planet orbit, the possible existence of an additional planet in the system, and the presence of $δ$ Scuti pulsations in the hosting star make this system a highly interesting object to help us understand the origin and evolution of giant planets orbiting very close a star. High spatial resolution imaging allows the study of the presence of the predicted additional planet, and any other objects, constraining the possible formation scenarios of the system. In November 2010, we recorded high spatial resolution images from 1 to 2.5 $μ$m using the W.M. 10m-Keck II telescope and its adaptive optics system, obtaining broad (Jc,Hc, and Kc) and narrow band (FeII) images of the system. After data reduction, the contrast and angular resolution provided by this instrument allowed us to constraint the multiplicity of this system and to detect one potential companion. We have found a new object at a distance of 1.961$"$ $\pm$ 0.003$"$ from the WASP-33, with a position angle of 276.32$\pm$0.24 deg. It could be a dwarf star/ brown dwarf or an extragalactic object. In the first case, and assuming the same distance from the Sun, the object is 227 AU from the central star. On the other hand, no additional objects have been found. This constraints the possible objects in the system, depending on its age and masses. A potential companion object to WASP-33 was obtained. The gravitational link must be confirmed, but this object could influence the evolution of the planetary system depending on its orbital eccentricity. We have ruled-out the existence of additional objects, depending on the age of the system.

Genetic and epigenetic factors in a mouse model for multifactorial cleft lip
Creators: name: Plamondon, Jenna Ashley
Publisher: name: University of British Columbia

description: Cleft lip (CL/P) is a human birth defect with complex genetic etiology. Two loci are involved in CL/P in the A/WySn mouse model: Wnt9b on Chromosome 11 and clf2 on Chromosome 13. There are two known mutant alleles at Wnt9b; clf1 is a spontaneous recessive mutation caused by an insertion of an IAP transposon near the gene Wnt9b and the second allele is a Wnt9b knock out. Clf2 is the second locus required for the CL/P phenotype. Quantitative PCR was used to investigate expression of other genes that might be affected by the absence of Wnt9b expression. Expression levels of Bmp4, Dkk1, Msx1, Msx2, Raldh3, Sox11, Wnt3, Wnt4 and β-catenin were examined. This experiment detected a significant decrease in expression levels of β-catenin in Wnt9bNull/Null embryos. The clf2 gene has not yet been identified and the function was unknown. Segregants from multi-generation crosses using the Wnt9b knockout, “Cross 1” and “Cross 2”, were examined for CL/P and genotype at polymorphic markers linked to Wnt9b and clf2 to ask whether clf2 modifies the frequency of CL in the Wnt9b null homozygotes. I also used recombinants from a congenic stock, consulted the mouse genome assembly and examined ancestral haplotypes in a strain survey to define the clf2 candidate region and examined mouse genome databases to develop a candidate gene list. My studies have reduced the clf2 candidate region to a 3.0 mb region between Cntnap3 and Ak029746. This region contains 48 genes and a majority of them encode zinc finger proteins. The specific crosses gave unexpected results that interfered with the ability to study the effect of clf2 genotype on penetrance of CL/P; the limited data suggested that clf2 does not affect penetrance of CL/P in the Wnt9b null embryos. However, Cross 2 provided an inverse way to address the role of clf2: to test whether clf2 modifies the methylation of the IAP transposon at Wnt9b in the clf1 mutant allele. Using the COBRA technique we studied the methylation levels of the IAP in Wnt9bclf1/Null embryos segregating at clf2. The results indicated that clf2 modifies the methylation status of the IAP.

description: The differential and total cross sections for electron capture by positrons from helium atoms are calculated using a first-order distorted wave theory satisfying the Coulomb boundary conditions. In this formalism a parametric potential is used to describe the electron screening in a consistent and realistic manner. The present procedure is self consistent because (i) it satisfies the correct boundary conditions and post-prior symmetry, and (ii) the potential and the electron binding energies appearing in the transition amplitude are consistent with the wave functions describing the collision system. The results are compared with the other theories and with the available experimental measurements. At the considered range of collision energies, the results agree reasonably well with recent experiments and theories.

description: Effective provisioning in the cloud demands an understanding of application workload dynamics. Current methods are extremely challenged given the mix and diversity of workloads and their on-demand deployment. This dissertation examines cloud workloads through statistical analysis to determine their salient features. These are employed to address three important issues in cloud environments: 1) Isolation of statistical models that accurately capture workload dynamics 2) Forecasting such workloads over short and long timescales, and 3) Resource provisioning to meet workload Quality-of-Service (QoS) requirements. A diverse set of traces from production cloud environments was analyzed. Henceforth a methodology was developed, one that classifies cloud workloads according to their distinguishing statistical features. This methodology has enabled the isolation of a novel statistical model that describes salient features specific to cloud storage workloads. The model employs current methods from econometrics described as Autoregressive Conditional Score (ACS) in this realization. The forecasting algorithm realized from this model improves accuracy over existing methods, reducing forecasting errors by 10% up to 25%. The algorithm has been realized in MATLAB and integrated into the R statistical computing package. Furthermore, this model has inspired the development of a novel measure of workload burstiness, its variance, one that extends current measures by employing statistical features specific to each workload. That is, if a workload demonstrates standard or nonstandard variance properties, the burstiness is calculated accordingly. It is described as the Normalized Score Index (NSI). It also provides a means for burstiness comparison which facilitates resource provisioning given its [0,1] range expressible as a percentage. Thus workloads with scores of 0.2 and 0.6 are assigned resources by their scores. Regarding resource provisioning, two novel algorithms have been realized each integrated as rate-based solutions applicable at integral points in cloud networks. The first targets the cloud network edge using the NSI in bandwidth provisioning. This was realized as a rate-adaptive framework applicable in virtualized cloud environments. The second algorithm is developed specifically as a scalable solution given enterprise cloud infrastructure. The methods have been tested under diverse conditions and found to provide tractable bandwidth assurance and foster QoS provisioning in dynamic cloud environments.

description: We consider sneutrino inflation and post-inflation cosmology in the singlet extension of the MSSM with approximate Peccei-Quinn(PQ) symmetry, assuming that supersymmetry breaking is mediated by gauge interaction. The PQ symmetry is broken by the intermediate-scale VEVs of two flaton fields, which are determined by the interplay between radiative flaton soft masses and higher order terms. Then, from the flaton VEVs, we obtain the correct mu term and the right-handed(RH) neutrino masses for see-saw mechanism. We show that the RH sneutrino with non-minimal gravity coupling drives inflation, thanks to the same flaton coupling giving rise to the RH neutrino mass. After inflation, extra vector-like states, that are responsible for the radiative breaking of the PQ symmetry, results in thermal inflation with the flaton field, solving the gravitino problem caused by high reheating temperature. Our model predicts the spectral index to be n_s\simeq 0.96 due to the additional efoldings from thermal inflation. We show that a right dark matter abundance comes from the gravitino of 100 keV mass and a successful baryogenesis is possible via Affleck-Dine leptogenesis.

Mixed volumes and mixed integrals

description: In recent years, mathematicians have developed new
approaches to study convex sets: instead of considering
convex sets themselves, they explore certain functions
or measures that are related to them. Problems
from convex geometry become thereby accessible to
analytic and probabilistic tools, and we can use these
tools to make progress on very difficult open problems.
We discuss in this Snapshot such a functional extension
of some “volumes” which measure how “big”
a set is. We recall the construction of “intrinsic volumes”,
discuss the fundamental inequalities between
them, and explain the functional extensions of these
results.
