description: We present computations of nucleosynthesis in low-mass red-giant-branch and asymptotic-giant-branch stars of Population I experiencing extended mixing. We adopt the updated version of the FRANEC evolutionary model, a new post-process code for non-convective mixing and the most recent revisions for solar abundances. In this framework, we discuss the effects of recent improvements in relevant reaction rates for proton captures on intermediate-mass nuclei (from carbon to aluminum). For each nucleus we briefly discuss the new choices and their motivations. The calculations are then performed on the basis of a parameterized circulation, where the effects of the new nuclear inputs are best compared to previous works. We find that the new rates (and notably the one for the 14N(p,g)15O reaction) imply considerable modifications in the composition of post-main sequence stars. In particular, the slight temperature changes due to the reduced efficiency of proton captures on 14N induce abundance variations at the first dredge up (especially for 17O, whose equilibrium ratio to 16O is very sensitive to the temperature). In this new scenario presolar oxide grains of AGB origin turn out to be produced almost exclusively by very-low mass stars (M<=1.5-1.7Msun), never becoming C-rich. The whole population of grains with 18O/16O below 0.0015 (the limit permitted by first dredge up) is now explained. Also, there is now no forbidden area for very low values of 17O/16O (below 0.0005), contrary to previous findings. A rather shallow type of transport seems to be sufficient for the CNO changes in RGB stages. Both thermohaline diffusion and magnetic-buoyancy-induced mixing might provide a suitable physical mechanism for this. Thermohaline mixing is in any case certainly inadequate to account for the production of 26Al on the AGB. Other transport mechanisms must therefore be at play.

description: To reduce the thickness of CuIn1-xGaxSe2 (CIGSe) solar cells, light management concepts must be used. One concept is the combination of an Al/indium1-tin1-oxide (ITO) reflector/contact and an optical scattering element at the back side of the device. Herein, nanostructured substrates, obtained by laser interference lithography and lift-off process, are covered with an Al/ITO back contact. Structure dimensions are a pitch of 1.96 μm and heights of 100–700 nm. Solar cells with 600 nm CIGSe absorber having this integrated structured back reflector exhibit an increase in JSC of up to 3.2 mA cm−2 compared with the Mo reference sample of identical thickness. To understand this optical gain, 3D finite-difference time-domain (FDTD) simulations are performed. To this end, a model is built to simulate structure formation. It is shown that locally enhanced optical absorption can be achieved by the integrated structured back reflector. It is also shown that parasitic absorption in the back ITO diffusion barrier needs to be minimized.
Analysis of Linear Time-Varying & Periodic Systems

description: This thesis applies Floquet theory to analyze linear periodic time-varying (LPTV) systems, represented by a system of ordinary differential equations (ODEs) that depend on a time variable t and have a matrix of coefficients with period T>0. The transition matrix of an LPTV system represented by a square periodic-function matrix A(t)=A(t+T) can be expressed as the product of a square periodic function matrix P(t)=P(t+T) and an exponentiated square matrix of the form Rt, where R is a constant matrix (independent of t). Despite the validity of Floquet theory, it is difficult to find an analytical closed form for the matrices P(t) and R when the transition matrix Φ_A (t,t_0 ) is unknown. In essence, it is difficult to find an analytical solution for an LPTV system (i.e., a closed form for its transition matrix). The research results show that for a given family of periodic matrices A(t), we can compare the powers of ω that multiply the harmonics (i.e., ω is part of the coefficients multiplying the cosine [sine] factors in even [odd] representations or of the exponential factors in complex representations) to determine the matrices P(t) and R. In addition, the results lead to relations between LPTV systems at frequency ω and the associated linear time-invariant system, which is defined by having zero frequency (ω=0).

description: I first met Leo Breiman in 1979 at the beginning of his third career, Professor of Statistics at Berkeley. He obtained his PhD with Loéve at Berkeley in 1957. His first career was as a probabilist in the Mathematics Department at UCLA. After distinguished research, including the Shannon--Breiman--MacMillan Theorem and getting tenure, he decided that his real interest was in applied statistics, so he resigned his position at UCLA and set up as a consultant. Before doing so he produced two classic texts, Probability, now reprinted as a SIAM Classic in Applied Mathematics, and Statistics. Both books reflected his strong opinion that intuition and rigor must be combined. He expressed this in his probability book which he viewed as a combination of his learning the right hand of probability, rigor, from Loéve, and the left-hand, intuition, from David Blackwell.

Role of regulatory T cells in obesity and insulin resistance
Creators: name: Wu, Dan
Publisher: name: University of British Columbia

description: Adipose tissue (AT)-resident regulatory T cells (Tregs) are important regulators of local and systemic inflammation and metabolism. We have previously found that insulin receptor signaling inhibits Treg suppressive function in vitro, and hyperinsulinemia is associated with alterations in visceral AT Tregs in vivo. To directly test the role of Treg-intrinsic insulin receptor signaling, we generated Foxp3(cre)InsR(fl/fl) mice and fed them either chow or high-fat diet (HFD) to induce hyperinsulinemia and obesity. Compared to Foxp3(cre) mice, Foxp3(cre)InsR(fl/fl) mice had improved glucose tolerance and insulin sensitivity after 13 weeks of HFD. This protective metabolic effect was associated with increased brown AT ST2+ Treg numbers and functions and dampened AT inflammation in Foxp3(cre)InsR(fl/fl) mice, rather than changes in food consumption or energy expenditure. Moreover, Foxp3(cre)InsR(fl/fl) mice were protected from age-associated glucose intolerance and insulin resistance as determined in 52-week-old mice. Unlike in the HFD cohort, visceral AT Treg numbers and functions were greatly reduced in aged Foxp3(cre)InsR(fl/fl) mice, leading to increased inflammation in the visceral AT. Surprisingly, elevated AT inflammation was associated with improved metabolic outcomes. Gene expression analysis revealed differential gene signatures in AT Tregs and total AT inflammation, suggesting that the underlying mechanisms contributing to the metabolic syndromes were distinct between the two insulin resistance models. Together, these data suggest that hyperinsulinemia contributes to metabolic syndrome in part by differentially affecting Treg control of AT inflammation in diet-induced versus age-associated metabolic syndrome. In mice, lean visceral AT is populated with anti-inflammatory cells, notably Tregs expressing the IL-33 receptor ST2. Conversely, obese AT contains fewer Tregs and more pro-inflammatory cells. In humans, however, there is limited evidence for a similar pattern of obesity-associated immunomodulation. We used flow cytometry and mRNA quantification to characterize human omental AT in 29 obese individuals, 18 of whom had T2D. Omental AT Treg frequencies negatively correlated to BMI but were comparable between T2D and non-T2D individuals. Compared to human thymic Tregs, omental AT Tregs had a distinct gene signature. ST2, however was not detectable on omental AT Tregs from lean or obese subjects.

description: We introduce a simple model to study movie competition in the recommender systems. Movies of heterogeneous quality compete against each other through viewers' reviews and generate interesting dynamics of box-office. By assuming mean-field interactions between the competing movies, we show that run-away effect of popularity spreading is triggered by defeating the average review score, leading to hits in box-office. The average review score thus characterizes the critical movie quality necessary for transition from box-office bombs to blockbusters. The major factors affecting the critical review score are examined. By iterating the mean-field dynamical equations, we obtain qualitative agreements with simulations and real systems in the dynamical forms of box-office, revealing the significant role of competition in understanding box-office dynamics.

description: Targeting influential nodes in complex networks allows fastening or hindering rumors, epidemics, and electric blackouts. Since communities are prevalent in real-world networks, community-aware centrality measures exploit this information to target influential nodes. Researches show that they compare favorably with classical measures that are agnostic about the community structure. Although the diffusion process is of prime importance, previous studies consider mainly the famous Susceptible-Infected-Recovered (SIR) epidemic propagation model. This work investigates the consistency of previous analyses using the popular Linear Threshold (LT) propagation model, which characterizes many spreading processes in our real life. We perform a comparative analysis of seven influential community-aware centrality measures on thirteen real-world networks. Overall, results show that Community-based Mediator, Comm Centrality, and Modularity Vitality outperform the other measures. Moreover, Community-based Mediator is more effective on a tight budget (i.e., a small fraction of initially activated nodes), while Comm Centrality and Modularity Vitality perform better with a medium to a high fraction of initially activated nodes.

description: Identifying key nodes is crucial for accelerating or impeding dynamic spreading in a network. Community-aware centrality measures tackle this problem by exploiting the community structure of a network. Although there is a growing trend to design new community-aware centrality measures, there is no systematic investigation of the proposed measures' effectiveness. This study performs an extensive comparative evaluation of prominent community-aware centrality measures using the Susceptible-Infected-Recovered (SIR) model on real-world online social networks. Overall, results show that K-shell with Community and Community-based Centrality measures are the most accurate in identifying influential nodes under a single-spreader problem. Additionally, the epidemic transmission rate doesn't significantly affect the behavior of the community-aware centrality measures.

description: It is of paramount importance to uncover influential nodes to control diffusion phenomena in a network. In recent works, there is a growing trend to investigate the role of the community structure to solve this issue. Up to now, the vast majority of the so-called community-aware centrality measures rely on non-overlapping community structure. However, in many real-world networks, such as social networks, the communities overlap. In other words, a node can belong to multiple communities. To overcome this drawback, we propose and investigate the "Overlapping Modularity Vitality" centrality measure. This extension of "Modularity Vitality" quantifies the community structure strength variation when removing a node. It allows identifying a node as a hub or a bridge based on its contribution to the overlapping modularity of a network. A comparative analysis with its non-overlapping version using the Susceptible-Infected-Recovered (SIR) epidemic diffusion model has been performed on a set of six real-world networks. Overall, Overlapping Modularity Vitality outperforms its alternative. These results illustrate the importance of incorporating knowledge about the overlapping community structure to identify influential nodes effectively. Moreover, one can use multiple ranking strategies as the two measures are signed. Results show that selecting the nodes with the top positive or the top absolute centrality values is more effective than choosing the ones with the maximum negative values to spread the epidemic.

description: Protein$α$-helices provide an ordered biological environment that is conducive to soliton-assisted energy transport. The nonlinear interaction between amide I excitons and phonon deformations induced in the hydrogen-bonded lattice of peptide groups leads to self-trapping of the amide I energy, thereby creating a localized quasiparticle (soliton) that persists at zero temperature. The presence of thermal noise, however, could destabilize the protein soliton and dissipate its energy within a finite lifetime. In this work, we have computationally solved the system of stochastic differential equations that govern the quantum dynamics of protein solitons at physiological temperature, T=310 K, for either a single isolated $α$-helix spine of hydrogen bonded peptide groups or the full protein $α$-helix comprised of three parallel $α$-helix spines. The simulated stochastic dynamics revealed that although the thermal noise is detrimental for the single isolated $α$-helix spine, the cooperative action of three amide I exciton quanta in the full protein $α$-helix ensures soliton lifetime of over 30 ps, during which the amide I energy could be transported along the entire extent of an 18-nm-long $α$-helix. Thus, macromolecular protein complexes, which are built up of protein $α$-helices could harness soliton-assisted energy transport at physiological temperature. Because the hydrolysis of a single adenosine triphosphate molecule is able to initiate three amide I exciton quanta, it is feasible that multiquantal protein solitons subserve a variety of specialized physiological functions in living systems.

description: We compute higher-point superstring correlators involving spin fields in various even space-time dimensions D at tree-level and to arbitrary loop order. This generalizes previous work in D=4 space-time dimensions. The main focus are D=6,8 and D=10 superstring compactifications for which correlation functions with four and more spin fields are computed. More precisely, we present every non-vanishing six-point function. A number of results can even be derived for arbitrary D. A closed formula for the correlators with any number of fermions psi and two spin fields S in D space-time dimensions is given for arbitrary genus. Moreover, in D=6 and for arbitrary genus, we find a general formula for the correlators . The latter serve as basic building blocks to construct higher-point fermionic correlation functions. In D=8 we can profit from the SO(8)-triality to derive further tree-level correlators with a large numbers of spin fields.

description: The solutions to certain nested recursions, such as Conolly's C(n) = C(n-C(n-1))+C(n-1-C(n-2)), with initial conditions C(1)=1, C(2)=2, have a well-established combinatorial interpretation in terms of counting leaves in an infinite binary tree. This tree-based interpretation, which has a natural generalization to a k-term nested recursion of this type, only applies to homogeneous recursions, and only solves each recursion for one set of initial conditions determined by the tree. In this paper, we extend the tree-based interpretation to solve a non-homogeneous version of the k-term recursion that includes a constant term. To do so we introduce a tree-grafting methodology that inserts copies of a finite tree into the infinite k-ary tree associated with the solution of the corresponding homogeneous k-term recursion. This technique can also be used to solve the given non-homogeneous recursion with various sets of initial conditions.

description: The annihilation cross section of thermal relic dark matter determines both its relic density and indirect detection signals. We determine how large indirect signals may be in scenarios with Sommerfeld-enhanced annihilation, subject to the constraint that the dark matter has the correct relic density. This work refines our previous analysis through detailed treatments of resonant Sommerfeld enhancement and the effect of Sommerfeld enhancement on freeze out. Sommerfeld enhancements raise many interesting issues in the freeze out calculation, and we find that the cutoff of resonant enhancement, the equilibration of force carriers, the temperature of kinetic decoupling, and the efficiency of self-interactions for preserving thermal velocity distributions all play a role. These effects may have striking consequences; for example, for resonantly-enhanced Sommerfeld annihilation, dark matter freezes out but may then chemically recouple, implying highly suppressed indirect signals, in contrast to naive expectations. In the minimal scenario with standard astrophysical assumptions, and tuning all parameters to maximize the signal, we find that, for force-carrier mass m_phi = 250 MeV and dark matter masses m_X = 0.1, 0.3, and 1 TeV, the maximal Sommerfeld enhancement factors are S_eff = 7, 30, and 90, respectively. Such boosts are too small to explain both the PAMELA and Fermi excesses. Non-minimal models may require smaller boosts, but the bounds on S_eff could also be more stringent, and dedicated freeze out analyses are required. For concreteness, we focus on 4 mu final states, but we also discuss 4 e and other modes, deviations from standard astrophysical assumptions and non-minimal particle physics models, and we outline the steps required to determine if such considerations may lead to a self-consistent explanation of the PAMELA or Fermi excesses.

Fractalkine signaling in psychiatric disorder : observations in the postmortem brain
Creators: name: Hill, Sarah Louise
Publisher: name: University of British Columbia
Year: 2019

description: Schizophrenia (SCZ), bipolar disorder (BD), and major depressive disorder (MDD) are debilitating psychiatric illnesses. Though the pathophysiology underlying each disorder is not yet understood, previous studies have suggested that altered immune function may play a role, with microglia, the brain’s resident immune cells, implicated in this process. A recent genetic association study and meta-analysis of microarray data indicated that dysregulation of CX3CR1, a microglial G-protein coupled receptor, may be associated with SCZ. Signaling between CX3CR1 and its neuronal ligand, fractalkine (CX3CL1), is proposed to mediate neuron-microglia interactions, recruiting microglia to synaptic sites and modulating changes in microglial activation status. However, it remains to be determined whether fractalkine is dysregulated in SCZ, BD, or MDD, or if fractalkine signaling is associated with microglial morphology and activation status, or synaptic density in these disorders. To this end, we quantified mRNA and protein expression of fractalkine, CX3CR1, and the disintegrin-like metalloproteinase 10 (ADAM10), involved in ectodomain shedding of fractalkine, in postmortem brain tissue from individuals with SCZ, BD, MDD and matched controls. We detected a significant decrease in fractalkine protein levels in SCZ relative to controls, suggesting fractalkine-CX3CR1 signaling may be disrupted in this disorder. Correlations were observed between fractalkine, CX3CR1, microglial measures and pre-synaptic protein levels.

description: We present an analysis of high-resolution spectra of three core-helium-burning "clump" stars and two first ascent giants in the open cluster IC 4651. Atmospheric parameters (T_eff, log_g, v_t, and [Fe/H]) were determined in our previous study by Carretta et al. (2004). In this study we present abundances of C, N, O and up to 24 other chemical elements. Abundances of carbon were derived using the C_2 Swan (0,1) band head at 5635.5 A. The wavelength interval 7980-8130 A, with strong CN features, was analysed in order to determine nitrogen abundances and 12^C/13^C isotope ratios. The oxygen abundances were determined from the [O i] line at 6300 A. Compared with the Sun and other dwarf stars of the Galactic disk, mean abundances in the investigated clump stars suggest that carbon is depleted by about 0.3 dex, nitrogen is overabundant by about 0.2 dex and oxygen is close to solar. This has the effect of lowering the mean C/N ratio to 1.36 +- 0.11. The mean 12^C/13^C ratios are lowered to 16 +- 2. Other investigated chemical elements have abundance ratios close to the solar ones.

description: We present a scheme to improve the noise threshold for the fault-tolerant topological one-way computation with a constant overhead. Certain cluster states of finite size, say star clusters, are constructed with logical qubits through an efficient verification process to achieve high fidelity. Then, the star clusters are connected near-deterministically with verification to form a three-dimensional cluster state to implement the topological one-way computation. The necessary postselection for verification is localized within the star clusters, ensuring the salability of computation. This scheme works with a high error rate $ \sim 1 % $ and reasonable resources comparable to or less than those for the other fault-tolerant schemes, suggesting potentially a noise threshold higher than 5%.

description: Focus of this work is to recognize standards and further features directly from 3D CAD models. For this reason, a neural network was trained to recognize nine classes of machine elements. After the system identified a part as a standard, like a hexagon head screw after the DIN EN ISO 8676, it accesses the geometrical information of the CAD system via the Application Programming Interface (API). In the API, the system searches for necessary information to describe the part appropriately. Based on this information standardized parts can be recognized in detail and supplemented with further information.
Non-photonic electron-hadron correlations and non-photonic electron $v_2$ at STAR/RHIC

description: Non-photonic electrons (when $p_T >$ 3 GeV/$c$) represent the directions of the parent heavy quarks, and their angular correlations with charged hadrons provide a unique tool to study the relative contributions from $D$ and B meson decays in p+p collisions, as well as the flavor-dependence of the energy loss mechanism in A+A collisions. We review the disentanglement of charm and bottom contributions to non-photonic electrons in p+p collisions at $\sqrt{s} = 200$ GeV at RHIC. B decay contribution is approximately 50$ at the electron transverse momentum of $p_{T} > 5$ GeV/$c$ from STAR results. Incorporating the energy loss information of non-photonic electrons, the result indicates a B meson suppression at high $p_T$ in heavy ion collisions. We also present non-photonic electron-hadron correlations in d+Au collisions as a baseline reference for the investigation of the heavy quark energy loss in A+A collisions. Heavy quark energy loss and heavy quark evolution in the QCD medium can lead to a finite "elliptic flow" parameter ($v_2$) of $D$ and $B$ mesons which can be studied through $v_2$ of non-photonic electrons. Preliminary $v_2$ measurements for non-photonic electrons are shown to be lower than $v_2$ of charged hadrons (or $K_S^0$, $Λ$) for 200 GeV Au+Au collisions.

description: We propose a novel deep learning based denoising filter selection algorithm for noisy Electrocardiograph (ECG) signal preprocessing. ECG signals measured under clinical conditions, such as those acquired using skin contact devices in hospitals, often contain baseline signal disturbances and unwanted artefacts; indeed for signals obtained outside of a clinical environment, such as heart rate signatures recorded using non-contact radar systems, the measurements contain greater levels of noise than those acquired under clinical conditions. In this paper, we focus on heart rate signals acquired using non-contact radar systems for use in assisted living environments. Such signals contain more noise than those measured under clinical conditions and thus require a novel signal noise removal method capable of adaptive determining filters. Currently, the most common method of removing noise from such a waveform is through the use of filters; the most popular filtering method amongst which is the wavelet filter. There are, however, circumstances in which using a different filtering method may result in higher signal-to-noise-ratios (SNR) for a waveform; in this paper, we investigate the wavelet and elliptical filtering methods for the task of reducing noise in ECG signals acquired using assistive technologies. Our proposed convolutional neural network architecture classifies (with 92.8% accuracy) the optimum filtering method for noisy signal based on its expected SNR value.
