description: The brain keeps its overall dynamics in a corridor of intermediate activity and it has been a long standing question what possible mechanism could achieve this task. Mechanisms from the field of statistical physics have long been suggesting that this homeostasis of brain activity could occur even without a central regulator, via self-organization on the level of neurons and their interactions, alone. Such physical mechanisms from the class of self-organized criticality exhibit characteristic dynamical signatures, similar to seismic activity related to earthquakes. Measurements of cortex rest activity showed first signs of dynamical signatures potentially pointing to self-organized critical dynamics in the brain. Indeed, recent more accurate measurements allowed for a detailed comparison with scaling theory of non-equilibrium critical phenomena, proving the existence of criticality in cortex dynamics. We here compare this new evaluation of cortex activity data to the predictions of the earliest physics spin model of self-organized critical neural networks. We find that the model matches with the recent experimental data and its interpretation in terms of dynamical signatures for criticality in the brain. The combination of signatures for criticality, power law distributions of avalanche sizes and durations, as well as a specific scaling relationship between anomalous exponents, defines a universality class characteristic of the particular critical phenomenon observed in the neural experiments. The spin model is a candidate for a minimal model of a self-organized critical adaptive network for the universality class of neural criticality. As a prototype model, it provides the background for models that include more biological details, yet share the same universality class characteristic of the homeostasis of activity in the brain.

description: There is evidence that ice age cycles are paced by astronomical forcing, suggesting some kind of synchronisation phenomenon. Here, we identify the type of such synchronisation and explore systematically its uniqueness and robustness using a simple paleoclimate model akin to the van der Pol relaxation oscillator and dynamical system theory. As the insolation is quite a complex quasiperiodic signal involving different frequencies, the traditional concepts used to define synchronisation to periodic forcing are no longer applicable. Instead, we explore a different concept of generalised synchronisation in terms of (coexisting) synchronised solutions for the forced system, their basins of attraction and instabilities. We propose a clustering technique to compute the number of synchronised solutions, each of which corresponds to a different paleoclimate history. In this way, we uncover multistable synchronisation (reminiscent of phase- or frequency-locking to individual periodic components of astronomical forcing) at low forcing strength, and monostable or unique synchronisation at stronger forcing. In the multistable regime, different initial conditions may lead to different paleoclimate histories. To study their robustness, we analyse Lyapunov exponents that quantify the rate of convergence towards each synchronised solution (local stability), and basins of attraction that indicate critical levels of external perturbations (global stability). We find that even though synchronised solutions are stable on a long term, there exist short episodes of desynchronisation where nearby climate trajectories diverge temporarily (for about 50 kyr).

description: We show that a class of Einstein-Maxwell-Dilaton (EMD) theories are related to higher dimensional AdS-Maxwell gravity via a dimensional reduction over compact Einstein spaces combined with continuation in the dimension of the compact space to non-integral values (`generalized dimensional reduction'). This relates (fairly complicated) black hole solutions of EMD theories to simple black hole/brane solutions of AdS-Maxwell gravity and explains their properties. The generalized dimensional reduction is used to infer the holographic dictionary and the hydrodynamic behavior for this class of theories from those of AdS. As a specific example, we analyze the case of a black brane carrying a wave whose universal sector is described by gravity coupled to a Maxwell field and two neutral scalars. At thermal equilibrium and finite chemical potential the two operators dual to the bulk scalar fields acquire expectation values characterizing the breaking of conformal and generalized conformal invariance. We compute holographically the first order transport coefficients (conductivity, shear and bulk viscosity) for this system.

description: The physics of self-sustained oscillations in the phenomenon of positive glow corona is presented. The dynamics of charged-particle oscillation under static electric field has been briefly outlined; and, the resulting self-sustained current oscillations in the electrodes have been compared with the measurements from the positive glow corona experiments. The profile of self-sustained electrode current oscillations predicted by the presented theory qualitatively agrees with the experimental measurements. For instance, the experimentally observed saw-tooth shaped electrode current pulses are reproduced by the presented theory. Further, the theory correctly predicts the pulses of radiation accompanying the abrupt rises in the saw-tooth shaped current oscillations, as verified from the various glow corona experiments.

description: We model the robustness against random failure or intentional attack of networks with arbitrary large-scale structure. We construct a block-based model which incorporates --- in a general fashion --- both connectivity and interdependence links, as well as arbitrary degree distributions and block correlations. By optimizing the percolation properties of this general class of networks, we identify a simple core-periphery structure as the topology most robust against random failure. In such networks, a distinct and small "core" of nodes with higher degree is responsible for most of the connectivity, functioning as a central "backbone" of the system. This centralized topology remains the optimal structure when other constraints are imposed, such as a given fraction of interdependence links and fixed degree distributions. This distinguishes simple centralized topologies as the most likely to emerge, when robustness against failure is the dominant evolutionary force.

The relationship between dynamic knee joint load and matrix metalloproteinases in people with and without knee osteoarthritis
Creators: name: Bahar, Mohammadreza
Publisher: name: University of British Columbia
Year: 2013

description: Introduction: Knee osteoarthritis (OA) is a destructive joint disease resulting from a number of factors including excessive and repetitive loading of the joints. Even though OA symptoms begin mostly in midlife, the degenerative changes of articular cartilage take place a long time before the onset, so it is important to track osteoarthritic changes at earlier phases. Radiology imaging is widely used for this purpose; however, radiology does not show minute changes that occur before onset of OA symptoms. Due to such limitations, the investigation of molecular changes is growing in today’s research. Matrix metalloproteinases (MMPs) are degenerative enzymes of connective tissue and their quantities are thought to be related to OA changes. Our goal was to investigate how MMP variance is explained by OA–related factors, mainly dynamic knee joint loading. Methods: A cross-sectional design was used to collect data on the intraarticular knee joint load, reflected by knee adduction moment (KAM), as well as serum samples in 28 participants of which half had mild to severe OA and the other half were OA-free. Laboratory-based motion analysis was used to compute the KAM, while MMP levels (MMPs- 1, 3, 13) were measured using ELISA. Multiple-regression analysis was used to investigate the explanatory role of KAM, and potential confounders like age, and OA severity in explaining MMP variance. Results: KAM impulse predicted significant variance in MMP-3 levels (R²=0.197, p=0.018). After controlling for the effect of age and severity, the explanatory role of KAM impulse was decreased (R²=0.157), still remaining statistically significant (p=0.036). The explained variance of MMP-1, 13 did not reveal statistical significance from explanatory variables. Conclusion: This research provides evidence of a positive relationship between MMP- 3 and intraarticular knee joint load, quantified by the KAM. The relationship remained significant after controlling for age and OA severity. Our findings support the notion that MMP-3 may be a candidate for OA investigations. Since MMP levels are influenced by a number of factors, it seems logical to consider the levels of other biomarkers along with them.

description: Background: Neutron-induced backgrounds are a significant concern for experiments that require extremely low levels of radioactive backgrounds such as direct dark matter searches and neutrinoless double-beta decay experiments. Unmeasured neutron scattering cross sections are often accounted for incorrectly in Monte Carlo simulations. Purpose: Determine partial gamma-ray production cross sections for (n,xng) reactions in natural argon for incident neutron energies between 1 and 30 MeV. Methods: The broad spectrum neutron beam at the Los Alamos Neutron Science Center (LANSCE) was used used for the measurement. Neutron energies were determined using time-of-flight and resulting gamma rays from neutron-induced reactions were detected using the GErmanium Array for Neutron Induced Excitations (GEANIE). Results: Partial gamma-ray cross sections were measured for six excited states in Ar-40 and two excited states in Ar-39. Measured (n,xng) cross sections were compared to the TALYS and CoH3 nuclear reaction codes. Conclusions: These new measurements will help to identify potential backgrounds in neutrinoless double-beta decay and dark matter experiments that use argon as a detection medium or shielding. The measurements will also aid in the identification of neutron interactions in these experiments through the detection of gamma rays produced by (n,xng) reactions.

description: Lifting operators play an important role in starting a lattice Boltzmann model from a given initial density. The density, a macroscopic variable, needs to be mapped to the distribution functions, mesoscopic variables, of the lattice Boltzmann model. Several methods proposed as lifting operators have been tested and discussed in the literature. The most famous methods are an analytically found lifting operator, like the Chapman-Enskog expansion, and a numerical method, like the Constrained Runs algorithm, to arrive at an implicit expression for the unknown distribution functions with the help of the density. This paper proposes a lifting operator that alleviates several drawbacks of these existing methods. In particular, we focus on the computational expense and the analytical work that needs to be done. The proposed lifting operator, a numerical Chapman-Enskog expansion, obtains the coefficients of the Chapman-Enskog expansion numerically. Another important feature of the use of lifting operators is found in hybrid models. There the lattice Boltzmann model is spatially coupled with a model based on a more macroscopic description, for example an advection-diffusion-reaction equation. In one part of the domain, the lattice Boltzmann model is used, while in another part, the more macroscopic model. Such a hybrid coupling results in missing data at the interfaces between the different models. A lifting operator is then an important tool since the lattice Boltzmann model is typically described by more variables than a model based on a macroscopic partial differential equation.

description: Carbon nanotubes provide one of the most accessible experimental realizations of one dimensional electron systems. In the experimentally relevant regime of low doping the Luttinger liquid formed by electrons may be approximated by a Wigner crystal. The crystal-like electronic order suggests that nanotubes exhibit effects similar to the Mössbauer effect where the momentum of an emitted photon is absorbed by the whole crystal. We show that the circular photovoltaic effect in chiral nanotubes is of the same nature. We obtain the frequency dependence of the photovoltage and characterize its singularities in a broad frequency range where the electron correlations are essential. Our predictions provide a basis for using the photogalvanic effect as a new experimental probe of electron correlations in nanotubes.

The relationship between T and B cell hepatitis B virus vaccine-specific responses in a cohort of healthy infants
Creators: name: Gelinas, Laura Clinckett
Publisher: name: University of British Columbia
Year: 2013

description: Vaccines are one of the greatest medical triumphs. Due to the empirical nature of vaccine development, however, it is still unclear how we maintain immunological memory and protection following vaccination. Using cells from a cohort of healthy infants and the hepatitis B virus (HBV) vaccine as a model, I developed a vaccine-specific stimulation assay that detects multiple immune readouts simultaneously from memory T cells in response to antigen stimulation in vitro. By stratifying my cohort by their anti-HBV surface antigen antibody (anti-HBs) titers, I determined how their HBV-specific memory T cell immune responses differed stratified by serological response. Based on my results, interferon (IFN)-γ appeared to be the most consistent predictor of a stronger serological response to HBV vaccination. The most striking trend was a positive correlation between bulk IFN-γ secretion and anti-HBs titers at 6 and 18 months following vaccination. A similar trend was noted for interleukin (IL)-10 secretion, but it did not extend past the 6-month time point. Tumor necrosis factor (TNF)-α, on the other hand, had a dynamic production profile. Overall, TNF-α production in proliferating CD8 T cells was increased in those subjects who produced lower levels of anti-HBs six months after vaccination. This observation was reversed by the 18-month time point—children who had anti-HBs titers less than 10 IU/l secreted lower levels of TNF-α. Many poor responders, as defined by their anti-HBs titers, demonstrated evidence of T cell memory either by HBsAg-specific proliferation, intracellular cytokine production, or cytokine secretion—indicating that an alternative or additional immunological mechanism might also correlate with vaccine-induced protection. The ultimate goal of this research project was to develop an in vitro antigen stimulation protocol that minimized sample usage and gathered data to help generate hypotheses regarding how the adaptive immune system, as a whole, responds to vaccination. The results from my study identified IFN-γ, TNF-α, as well as IL-10 as potential targets for continued investigation. However, in order to determine which immune parameters—whether humoral, cell-mediated, or even innate immunity—best predict strong and long-lasting immunological memory, we need to design more comprehensive longitudinal studies that extend beyond infancy.

description: The extragalactic background light (EBL), i.e., the diffuse meta-galactic photon field in the ultraviolet to infrared, is dominated by the emission from stars in galaxies. It is, therefore, intimately connected with the integrated star formation rate density (SFRD). In this paper, the SFRD is constrained using recent limits on the EBL density derived from observations of distant sources of high and very-high energy gamma-rays. The stellar EBL contribution is modeled utilizing simple stellar population spectra including dust attenuation and emission. For modeling the SFRD up to z=4 a broken power law function in z+1 is assumed. A wide range of values for the different model parameters (SFRD(z), metallicity, dust absorption) is investigated and their impact on the resulting EBL is studied. The calculated EBL densities are compared with the specific EBL density limits and constraints on the SFRD are derived. For the fiducial model, adopting a Chabrier initial mass function (IMF) and a second power law index for the SFRD of beta=0.3, the SFRD is constrained to

Year: 2025

description: This study aimed to implement the Analysis, Design, Development, Implementation, Evaluation (ADDIE) model to enhance the effectiveness of teaching colour painting in the training of future professionals. The methodology involved analysing the current teaching state in this course at Henan Technical College of Construction, combining traditional education with applying the ADDIE model. A comparative analysis was conducted between the learning outcomes of students using the ADDIE model and those taught using traditional methods. The ADDIE model facilitated the improvement of course structure, established clear learning objectives, and developed assessment mechanisms that took into account both theoretical knowledge and practical skills. The integration of blended design led to increased student engagement and interest in the subject. The results showed significant improvement in students’ abilities, knowledge, and practical skills. Furthermore, the new approach to assessment provided more accurate information on students’ knowledge levels and progress. The findings of the research indicate the effectiveness of the proposed model for teaching similar subjects in vocational institutions. A key aspect is the adaptation of educational methods to meet the modern requirements of professional training. The study examined the impact of technological innovations on the learning process and their role in shaping students’ competencies. The use of blended teaching methods not only increased student engagement but also fostered the development of creative thinking and visual perception. An important component of the research was the design of effective educational activities that promote the development of critical thinking and student autonomy. Various methods, such as group projects and creative tasks, enabled participants to present their ideas and receive feedback. This also boosted their motivation to learn, as students were able to apply their acquired knowledge in practice. Overall, the integration of the ADDIE model not only improved the quality of instruction but also created conditions for a deeper understanding of colour painting as an artistic discipline, which is essential in the training of professionals.

Adaptive sensing performance lower bounds for sparse signal detection and support estimation

description: This paper gives a precise characterization of the fundamental limits of adaptive sensing for diverse estimation and testing problems concerning sparse signals. We consider in particular the setting introduced in (IEEE Trans. Inform. Theory 57 (2011) 6222-6235) and show necessary conditions on the minimum signal magnitude for both detection and estimation: if ${\mathbf {x}}\in \mathbb{R}^n$ is a sparse vector with $s$ non-zero components then it can be reliably detected in noise provided the magnitude of the non-zero components exceeds $\sqrt{2/s}$. Furthermore, the signal support can be exactly identified provided the minimum magnitude exceeds $\sqrt{2\log s}$. Notably there is no dependence on $n$, the extrinsic signal dimension. These results show that the adaptive sensing methodologies proposed previously in the literature are essentially optimal, and cannot be substantially improved. In addition, these results provide further insights on the limits of adaptive compressive sensing.

description: In 2006 Masuda and Suh asked if two compact non-singular toric varieties having isomorphic cohomology rings are homeomorphic. In the first part of this paper we discuss this question for topological generalizations of toric varieties, so-called torus manifolds. For example we show that there are homotopy equivalent torus manifolds which are not homeomorphic. Moreover, we characterize those groups which appear as the fundamental groups of locally standard torus manifolds. In the second part we give a classification of quasitoric manifolds and certain six-dimensional torus manifolds up to equivariant diffeomorphism. In the third part we enumerate the number of conjugacy classes of tori in the diffeomorphism group of torus manifolds. For torus manifolds of dimension greater than six there are always infinitely many conjugacy classes. We give examples which show that this does not hold for six-dimensional torus manifolds.

description: We present integral field spectroscopy observations, covering the [O III]4959,5007 emission-line doublet of eight high-redshift (z=1.4-3.4) ultra-luminous infrared galaxies (ULIRGs) that host Active Galactic Nuclei (AGN) activity, including known sub-millimetre luminous galaxies (SMGs). The targets have moderate radio luminosities that are typical of high-redshift ULIRGs (L(1.4GHz)=10^(24)-10^(25)W/Hz) and therefore are not radio-loud AGN. We de-couple kinematic components due to the galaxy dynamics and mergers from those due to outflows. We find evidence in the four most luminous systems (L([O III])>~10^(43)erg/s) for the signatures of large-scale energetic outflows: extremely broad [O III] emission (FWHM ~ 700-1400km/s) across ~4-15kpc, with high velocity offsets from the systemic redshifts (up to ~850km/s). The four less luminous systems have lower quality data displaying weaker evidence for spatially extended outflows. We estimate that these outflows are potentially depositing energy into their host galaxies at considerable rates (~10^(43)-10^(45)erg/s); however, due to the lack of constraints on the density of the outflowing material and the structure of the outflow, these estimates should be taken as illustrative only. Based on the measured maximum velocities (v(max)~400-1400km/s) the outflows observed are likely to unbind some fraction of the gas from their host galaxies, but are unlikely to completely remove gas from the galaxy haloes. By using a combination of energetic arguments and a comparison to ULIRGs without clear evidence for AGN activity, we show that the AGN activity could be the dominant power source for driving all of the observed outflows, although star formation may also play a significant role in some of the sources.

description: We present a unifying framework to the understanding of when and how quantum mechanical systems become independent of their initial conditions and adapt macroscopic properties (like temperature) of the environment.By viewing this problem from an quantum information theory perspective, we are able to simplify it in a very natural and easy way. We first show that for any interaction between the system and the environment, and almost all initial states of the system, the question of how long the system retains memory of its initial conditions can be answered by studying the temporal evolution of just one special initial state. This special state thereby depends only on our knowledge of macroscopic parameters of the system. We provide a simple entropic inequality for this state that can be used to determine whether mosts states of the system have, or have not become independent of their initial conditions after time $t$. We discuss applications of our entropic criterion to thermalization times in systems with an effective light-cone and to quantum memories suffering depolarizing noise. We make a similar statement for almost all initial states of the environment, and finally provide a sufficient condition for which a system never thermalizes, but remains close to its initial state for all times.

Oligomerization dependent enzyme kinetics and mechanistic characterization of type I protein arginine N-methyltransferases
Creators: name: Thomas, Dylan
Publisher: name: University of British Columbia
Year: 2013

description: Protein arginine N-methyltransferases (PRMTs) constitute a family of post-translational modifying enzymes that modulate protein-protein interactions via the addition of methyl groups to arginine residues in protein substrates (1). PRMTs have been demonstrated to homooligomerize via a dimerization arm that binds with the outer surface of the S-adenosyl-Lmethionine (AdoMet) binding domain (2-5). In this body of work, I have demonstrated and quantified in vitro the strength of homodimerization for PRMT1 and PRMT6 and demonstrated that saturating concentrations of S-adenosyl-L-methionine (AdoMet) or S-adenosyl-Lhomocysteine (AdoHcy) respectively strengthen or weaken this interaction. This finding supports an ordered bisubstrate mechanism in which AdoMet binding promotes formation of the complete peptide-substrate binding groove through dimerization, and AdoHcy generation promotes dissociation of the dimeric complex and turnover of substrate. A kinetic study using HIV Tat peptides revealed oligomerization-dependent kinetic patterns with these substrates. Kinetic experiments were initially performed on HIV Tat peptide with novel ωN-substitutions to probe their ability to inhibit PRMT1, 4 and 6. It was found that these Tat-peptides act as substrate inhibitors for both PRMT1 and PRMT6 and that this substrate inhibition was mitigated as the enzyme concentration increased. A model was proposed that represents activity as the sum of each ordered oligomer in solution, with the monomer being uniquely susceptible to substrate inhibition. Diverging from strictly oligomerization effects, R1 fibrillarin-like peptide containing a single arginine was substituted to alter the pKa of the terminal guanidino group to better probe the physicochemical properties that control methyltransfer. Surprisingly, hydroxyl substituted R1 peptide demonstrated an enhanced catalytic constant with PRMT1. MS and MS² experiments demonstrate that only monomethylation occurs on substituted arginines with PRMT1, and that this addition is asymmetric. PRMT1 D51N, a catalytically compromised mutant, revealed the kcat as rate limiting in the presence of D₂O, and electrostatic potential maps indicate that deprotonation of hydroxyl substituted arginine produces a strong nucleophile capable of enhanced methyltransfer. Altogether, these studies support water mediated, ordered bisubstrate mechanism in which oligomerization modulates activity. Substrate inhibition and active site chemistry were investigated using novel chemically substituted peptide probes that highlight trends beyond what site-directed mutagenesis can reveal alone.

description: An important and incompletely answered question is whether a closed quantum system of many interacting particles can be localized by disorder. The time evolution of simple (unentangled) initial states is studied numerically for a system of interacting spinless fermions in one dimension described by the random-field XXZ Hamiltonian. Interactions induce a dramatic change in the propagation of entanglement and a smaller change in the propagation of particles. For even weak interactions, when the system is thought to be in a many-body localized phase, entanglement shows neither localized nor diffusive behavior but grows without limit in an infinite system: interactions act as a singular perturbation on the localized state with no interactions. The significance for proposed atomic experiments is that local measurements will show a large but nonthermal entropy in the many-body localized state. This entropy develops slowly (approximately logarithmically) over a diverging time scale as in glassy systems.
