description: This study is a review of current practices in 13 states to: (1) measure traffic congestion and its costs; and (2) manage congestion with programs and techniques that do not involve the building of new highway capacity. In regard to the measures of congestion, the findings suggest two broad conclusions: (a) the most popular measures are not LOS or volume to capacity ratios; but rather the direct measures of either average time to traverse the distance between two points, or the average speed of vehicles. These are sometimes used to construct estimates of delay during peak traffic periods. (b) Five of the 13 states are either using or trying to devise more complex measures of congestion, measures that include estimates of the various costs associated with congestion. Regarding congestion management, most of the 13 states are implementing the 10 congestion management techniques identified by the study. When asked to rank the most effective techniques, the top four were incident management programs, signal coordination, traffic management centers, and access management.

description: We show that, under some mild conditions, a bialgebra in an abelian and coabelian braided monoidal category has a weak projection onto a formally smooth (as a coalgebra) sub-bialgebra with antipode; see Theorem 1.12. In the second part of the paper we prove that bialgebras with weak projections are cross product bialgebras; see Theorem 2.12. In the particular case when the bialgebra $A$ is cocommutative and a certain cocycle associated to the weak projection is trivial we prove that $A$ is a double cross product, or biproduct in Madjid's terminology. The last result is based on a universal property of double cross products which, by Theorem 2.15, works in braided monoidal categories. We also investigate the situation when the right action of the associated matched pair is trivial.

description: Light sources on the scale of single molecules can be addressed and characterized on their proper sub-nanometer scale by scanning tunneling microscopy induced luminescence (STML). Such a source can be driven by defined short charge pulses while the luminescence is detected with sub-nanosecond resolution. We introduce an approach to concurrently image the molecular emitter, which is based on an individual defect, with its local environment along with its luminescence dynamics at a resolution of a billion frames per second. The observed dynamics can be assigned to the single electron capture occurring in the low-nanosecond regime. While the emitter's location on the surface remains fixed, the scanning of the tip modifies the energy landscape for charge injection to the defect. The principle of measurement is extendable to fundamental processes beyond charge transfer like exciton diffusion.

description: The integer $d$ is called an exponential divisor of $n=\prod_{i=1}^r p_i^{a_i}>1$ if $d=\prod_{i=1}^r p_i^{c_i}$, where $c_i \mid a_i$ for every $1\le i \le r$. The integers $n=\prod_{i=1}^r p_i^{a_i}, m=\prod_{i=1}^r p_i^{b_i}>1$ having the same prime factors are called exponentially coprime if $(a_i,b_i)=1$ for every $1\le i\le r$. In the paper we investigate asymptotic properties of certain arithmetic functions involving exponential divisors and exponentially coprime integers.

description: Despite the potential benefits of assistive technologies (ATs) for people with various disabilities, only around 7% of Chinese with disabilities have had an opportunity to use ATs. Even for those who have used ATs, the abandonment rate was high. Although China has the world's largest population with disabilities, prior research exploring how ATs are used and perceived, and why ATs are abandoned have been conducted primarily in North America and Europe. In this paper, we present an interview study conducted in China with 26 people with various disabilities to understand their practices, challenges, perceptions, and misperceptions of using ATs. From the study, we learned about factors that influence AT adoption practices (e.g., misuse of accessible infrastructure, issues with replicating existing commercial ATs), challenges using ATs in social interactions (e.g., Chinese stigma), and misperceptions about ATs (e.g., ATs should overcome inaccessible social infrastructures). Informed by the findings, we derive a set of design considerations to bridge the existing gaps in AT design (e.g., manual vs. electronic ATs) and to improve ATs' social acceptability in China.

Bulk Flow and Shear Moments of the SFI++ Survey

description: We find the nine bulk--flow and shear moments from the SFI++ survey, as well as for subsamples of group and field galaxies. We constrain the velocity power spectrum shape parameter $Γ$ in linear theory using these moments. A likelihood function for $Γ$ was found after marginalizing over the power spectrum amplitude $σ_8Ω_m^{0.6}$ using constraints obtained from comparisons between redshift surveys and peculiar velocity data. We have estimated the velocity noise $σ_*$ from the data since without it our results may be biased. We also performed a statistical analysis of the difference between the field and group catalogues and found that the results from each reflect the same underlying large scale flows. We found that we can constrain the power spectrum shape parameter to be $Γ=0.15^{+0.18}_{-0.08}$ for the groups catalogue and $Γ=0.09^{+0.04}_{-0.04}$ for the field galaxy catalogue in fair agreement with the value from WMAP.
Origin of ferroelectricity in the multiferroic barium fluorides BaMF4

description: We present a first principles study of the series of multiferroic barium fluorides with the composition BaMF4, where M is Mn, Fe, Co, or Ni. We discuss trends in the structural, electronic, and magnetic properties, and we show that the ferroelectricity in these systems results from the "freezing in" of a single unstable polar phonon mode. In contrast to the case of the standard perovskite ferroelectrics, this structural distortion is not accompanied by charge transfer between cations and anions. Thus, the ferroelectric instability in the multiferroic barium fluorides arises solely due to size effects and the special geometrical constraints of the underlying crystal structure.

description: Mechanical metamaterials with complex microstructures have superior physical properties such as graded stiffness, negative Poisson's ratio, and advantage in energy absorption. In recent years, origami provide many inspirations in the geometry structure of the metamaterials. Here we present a modular origami inspired reconfigurable metamaterial. Our approach exploits a transformable module consisted of the Sarrus linkage and planar four-bar linkage, and the modules are connected following a tessellation pattern to form a periodic structure. Different arrangements, module shapes and grid pattern of the metamaterial are discussed, and the loading capacity and stiffness variation are analysed experimentally. The proposed material can be used to realize reconfigurable structures or architectures over a wide range of length scales.

description: Within a first principles framework, we study the electronic structure of the recently synthesized polymeric coordination compound Cu(II)-2,5-bis(pyrazol-1-yl)-1,4-dihydroxybenzene (CuCCP), which has been suggested to be a good realization of a Heisenberg spin-1/2 chain with antiferromagnetic coupling. By using a combination of classical with ab initio quantum mechanical methods, we design on the computer reliable modified structures of CuCCP aimed at studying effects of Cu-Cu coupling strength variations on this spin-1/2 system. For this purpose, we performed two types of modifications on CuCCP. In one case, we replaced H in the linker by i) an electron donating group (NH2) and ii) an electron withdrawing group (CN), while the other modification consisted in adding H2O and NH3 molecules in the structure which change the local coordination of the Cu(II) ions. With the NMTO-downfolding method we provide a quantitative analysis of the modified electronic structure and the nature of the Cu-Cu interaction paths in these new structures and discuss its implications for the underlying microscopic model.

It has a luminosity of 3.828e26 Watts, and despite that we receive only 2 parts per billion of this, it allows for the Earth's life to thrive. Moreover, we know that the Sun has been shining in the same way for about 4.6 billion years (the age of the Earth) and will likely still do the same for another 5 billion years or so. The Sun's power engine, as well as the one of all the stars we see in the night sky, has for long been a mystery, but astronomers now have a good understanding of it.

Self-energy-functional theory for systems of interacting electrons with disorder

Year: 2006
Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

subject: FOS: Physical sciences

description: Based on a functional-integral formalism, a generalization of the self-energy-functional theory (SFT) is proposed which is applicable to systems of interacting electrons with disorder. Similar to the pure case without disorder, a variational principle is set up which gives the physical (disorder) self-energy as a stationary point of the (averaged) grand potential. Although the resulting self-energy functional turns out to be more complicated, the formal structure of the theory can be retained since the unknown part of the functional is universal. This allows to construct non-perturbative and thermodynamically consistent approximations via searching for a stationary point on a restricted domain of the functional. The theory and the possible approximations are worked out for models with local interactions and local disorder. This results in a derivation of different mean-field approaches and various cluster extensions, including well-known concepts as the statistical dynamical mean-field theory, the molecular coherent-potential approximation and the dynamical cluster approximation. Due to the common formal framework provided by the SFT, one achieves a general systematization of dynamical approaches, i.e. approaches based on the spectrum of one-particle excitations. New mean-field and new cluster schemes naturally appear in this framework and complement the existing ones. Their prospects for future applications are discussed.

The underemployment of B.C. college graduates
Creators: name: Cram, Daniel William
Publisher: name: University of British Columbia
Year: 2009

description: Underemployment is a much discussed but little researched topic. The thesis begins with a broad discussion of the theory and methodology underlying the recent research on underemployment. It then proceeds to a quantitative analysis of underemployment using data from the 1995 follow-up of B.C. college leavers from vocational, technical and two-year academic university transfer programs. The study finds that, overall, one third of B.C. college leavers were employed in jobs that did not require the level of education that they had attained. As expected, there were significant differences by field of study and subsequent occupation. The rate of underemployment among students from academic programs was eight times the rate of underemployment for students from vocational programs and twice that of students from career/technical programs. Additionally, almost a third of all college leavers were employed in Sales and Service occupations and roughly two-thirds of those were underemployed. Labour market segmentation theory provides the most useful theoretical explanation for these findings. The markedly uneven rates of underemployment experienced by college leavers in the core and peripheral sectors support the labour market segmentation perspective. In conclusion, underemployment is a useful, though limited construct. Such a measure should only be used in conjunction with other measures of employment outcomes like unemployment, salary and full/part-time employment status.
Chiral Symmetry Restoration and Deconfinement in the Contact Interaction Model of Quarks with a Parallel Electric and Magnetic Fields

description: We study the impact of steady, homogeneous, and external parallel electric and magnetic field strength ($eE\parallel eB$), on the chiral symmetry breaking-restoration and confinement-deconfinement phase transitions. We also sketch the phase diagram of quantum chromodynamics (QCD) at finite temperature $T$ and in the presence of background fields. Our unified formalism for this study is based on the Schwinger-Dyson equations, symmetry preserving vector-vector contact interaction model of quarks, and the proper time regularization scheme. At $T=0$, in the purely magnetic case ($eE\rightarrow 0$), we observe the well known magnetic catalysis effect. On the other hand, in the pure electric field background ($eB\rightarrow 0$), the electric field tends to restore the chiral symmetry and deconfinement above the pseudo-critical electric field $eE^{χ, C}_c$. In the presence of both $eE$ and $eB$: we find the magnetic catalysis effect in the particular region where $eB$ dominates over $eE$, whereas, we observe the chiral inhibition (or electric chiral rotation) effect, when $eE$ stand over $eB$. At finite $T$, in the pure electric field case, the phenomenon of inverse electric catalysis appears to exist in our model. On the other hand for pure magnetic field background, we notice the magnetic catalysis effect in the mean-field approximation and inverse magnetic catalysis with $eB$-dependent coupling. The combined effect of both $eE$ and $eB$ on the pseudo-critical $T^{χ, C}_c$ yields the inverse electromagnetic catalysis, with and without $eB-$dependent effective coupling of the model. Our findings are satisfactory in agreement with already predicted results by lattice simulations and other reliable effective models of QCD.

description: Intuitionistic fuzzy preference relations can take membership degrees, non-membership degrees, and hesitancy degrees into account during decision making. It has good practicability and flexibility in dealing with fuzzy and uncertain information. As for analytic network process, it is performed by thinking over the interaction and feedback relationships between criteria and indices, so that an effective method is provided for multi-criteria decision making. An index system with network structure for evaluating the bonds is presented, and a comprehensive method by combining the advantages of intuitionistic fuzzy preference relations and analytic network process is proposed to select and rank the bonds. A case study is given by the proposed method as well.

description: Chandra and XMM-Newton resolved extremely long tails behind two middle-aged pulsars, J1509-5850 and J1740+1000. The tail of PSR J1509-5850 is discernible up to 5.6' from the pulsar (6.5 pc at a distance of 4 kpc), with a flux of 2*10^{-13} erg s^{-1} cm^{-2} in 0.5-8 keV. The tail spectrum fits an absorbed power-law (PL) model with the photon index of 2.3\pm0.2, corresponding to the 0.5-8 keV luminosity of 1*10^{33} ergs s^{-1}, for n_H= 2.1*10^{22} cm^{-2}. The tail of PSR J1740+1000 is firmly detected up to 5' (2 pc at a 1.4 kpc distance), with a flux of 6*10^{-14} ergs cm^{-2} s^{-1} in 0.4-10 keV. The PL fit yields photon index of 1.4-1.5 and n_H=1*10^{21} cm^{-2}. The large extent of the tails suggests that the bulk flow in the tails starts as mildly relativistic downstream of the termination shock, and then gradually decelerates. Within the observed extent of the J1509-5850 tail, the average flow speed exceeds 5,000 km s^{-1}, and the equipartition magnetic field is a few times 10^{-5} G. For the J1740+1000 tail, the equipartition field is a factor of a few lower. The harder spectrum of the J1740+1000 tail implies either less efficient cooling or a harder spectrum of injected electrons. For the high-latitude PSR J1740+1000, the orientation of the tail on the sky shows that the pulsar is moving toward the Galactic plane, which means that it was born from a halo-star progenitor. The comparison between the J1509 and J1740 tails and the X-ray tails of other pulsars shows that the X-ray radiation efficiency correlates poorly with the pulsar spin-down luminosity or age. The X-ray efficiencies of the ram-pressure confined pulsar wind nebulae (PWNe) are systematically higher than those of PWNe around slowly moving pulsars with similar spin-down parameters.

description: Background: Substantial evidence indicates that maternal depression during pregnancy (i.e., antenatal depression) is associated not only with maternal wellbeing but also with child emotional and behavioural development. Children of antenatally depressed women are at risk of emotional and behavioural problems, including internalising problems (e.g., anxiety and depression) and externalising problems (e.g., attention problems), that may last at least to adolescence. These enduring effects also constitute an enormous economic cost. Despite the seriousness of this problem, until recently there existed very few controlled studies evaluating whether active psychological treatment for antenatal depression can prevent adverse child outcomes. Our previous pilot randomised controlled trial (RCT) exploring the effect of cognitive behavioural therapy (CBT) for antenatal depression on child outcomes showed promising results. We aim to assess whether treating antenatal depression with an evidence-based 8-week structured CBT program can prevent or ameliorate adverse child developmental outcomes at 2 years of age. Methods: Pregnant women ≤ 30 weeks gestation diagnosed with a depressive disorder are recruited and randomised to CBT or treatment as usual (TAU). The target sample size is 230 and the primary outcome measure is the infant Internalising scale of the Child Behaviour Checklist (CBCL) at 24 months of age. Secondary infant outcome measures at 24 months are the Externalising scale of the CBCL and the motor and cognitive development subscales of the Ages & Stages Questionnaire (ASQ-3). Additional secondary outcome measures are subscales of the Revised Infant Behaviour Questionnaire (IBQ-R), ASQ-3 and the ASQ-Socio-Emotional (ASQ-SE) at 3 and 12 months of age and the quality of mother-infant interaction at 3 and 24 months. Maternal measures, including demographic data, depression diagnosis, depressive and anxiety symptoms, perceived stress and parenting stress, are collected across all time points. Discussion: The trial is ongoing and recruitment was slowed due to the COVID-19 pandemic. If results suggest a beneficial effect of antenatal depression treatment on infant outcomes, the project could have repercussions for standard antenatal care, for maternal and infant health services and for preventing the intergenerational transmission of mental health disorders.

Imperfectives

description: This paper focuses on imperfective TAM (tense-aspect-mood) categories in Tlacochahuaya Zapotec, an Otomanguean language indigenous to the Tlacolula Valley in Oaxaca, Mexico. While the inflectional TAM morphology of Zapotec languages has been broadly described, both synchronically and diachronically, the semantics of these TAM categories is less robustly analyzed. This paper is the first step in my larger research plan to holistically describe the Tlacochahuaya Zapotec TAM system. The goal is to contribute to the descriptive literature on Zapotec languages and to provide a basis for meaningful diachronic studies of Zapotec TAM, which in turn would contribute to our typological understanding of TAM systems and semantic change. I approach Tlacochahuaya Zapotec imperfectives from three angles: (i) by considering the five imperfective TAM categories together to see how they delinate semantic (Aktionsart-based) verb categories (Chapter 2); (ii) by summarizing all the semantic contexts in which a single TAM category, the Imperfect r-, appears (Chapter 3); and (iii) by synthesizing analyses of imperfectives across Zapotec languages to probe the Proto-Zapotec system (Chapter 4). I conclude in Chapter 5.

description: We introduce two generalisations of the full symmetric inverse semigroup ${\mathcal{I}}_X$ and its dual semigroup ${\mathcal{I}^{\ast}}_X$ -- inverse semigroups ${\mathcal{PI}^{\ast}}_X$ and ${\overline{\mathcal{PI}^{\ast}}}_X$. Both of them have the same carrier and contain $\IS_X$. Binary operations on ${\mathcal{PI}^{\ast}}_X$ and ${\overline{\mathcal{PI}^{\ast}}}_X$ are reminiscent of the multiplication in ${\mathcal{I}}_X$. We use a convenient geometric way to realise elements from these two semigroups. This enables us to study efficiently their inner properties and to compare them with the corresponding properties of $\IS_X$ and ${\mathcal{I}^{\ast}}_X$.

description: Field measurement campaigns have grown exponentially in recent years, stemming from the need for reliable data to validate urban climate models and obtain a better understanding of urban climate features. Also contributing to this growth is the Local Climate Zone (LCZ) scheme, firstly developed to enhance the accuracy in the contextualisation of urban measurements, and lately used for characterising urban areas. Due to its relative novelty, researchers are still investigating the potential of LCZs and its indicators for urban temperature variability detection. In this respect, the present study introduces the results of an extensive monitoring campaign carried out in the city of Madrid over a two-year period (2016-2018). The aim of this work is to further examine the relationships between LCZs and air temperature differences, with emphasis on their hourly and seasonal evolution. A graphical and statistical analysis to identify temperature variability trends for each LCZ is performed. Results support the existing evidence suggesting a high level of effectiveness in capturing the heat island (UHI) profile of different urban areas, while underperforming when it comes to capturing diurnal temperature variability. The incorporation of indicators that explain the daytime temperature variation phenomenon into the LCZ scheme is therefore recommended, warranting further research.

Tet regulates nervous system development by controlling axon guidance
Creators: name: Tran, Hiep Hoang
Publisher: name: No Publisher Supplied
Year: 2023

description: Tet (Ten-eleven translocation) proteins are essential for animal development. They can regulate a variety of biological processes in cells in zygotic development, embryogenesis, or specific cell types during neuronal development. Tets can act in multiple layers to fine-tune the expression of important genes during development. The regulation can occur at both transcriptional and post-transcriptional levels. Mammalian TETs can control DNA demethylation to regulate the genomic methylation status. Tets can also interact with a wide variety of proteins, among them are epigenetic regulators, to control target gene expression independent of its DNA demethylation. In our study, we described Tet function in regulating 5hmrC (5-hydroxymethylribocytosine) mRNA modification which contributes to the post-transcriptional control of gene expression. Tet modified a selective subset of transcripts in the larval brain which are responsible for axonal and dendritic development including the axon guidance genes slit and robo2. The mRNA modification may occur cotranscriptionally facilitated by Tet binding to the target gene via its DNA-binding domain. The 5hmrC modification possibly affects the translation of the modified transcripts. The function of the Tet and its DNA-binding domain was further studied. Tet is required during the early pupal stage for normal brain development and a point mutation in the Tet DNA-binding domain (TetAXXC) exhibited strong axonal defects in the mushroom body structure of the brain. The phenotype is reminiscent of the Fmr1 mutant phenotype. Further study of the Tet DNA-binding domain mutant showed that glutamatergic signaling was altered in the mutation via downregulation of Gs2 (Glutamine synthetase 2). The down-regulation was also observed in Fmr1 (Fragile X messenger ribonucleoprotein 1) mutant. Restoring glutamatergic signaling by expressing Gs2 in insulin-producing cells, a group of neurosecretory cells in the Drosophila brain, can rescue axon guidance defects in both Tet and Fmr1 mutant brains. Thus, Tet also controls axon guidance in the developing brain through glutamatergic signaling. This study also uncovered the overlapping functions of Tet and Fmr1 and this has an important implication in neurodevelopmental research and therapy as several convergent pathways may be affected in both Tet and Fmr1-associated disorders. Taken together, Tet controls nervous system development by regulating axon guidance through both epigenetic and epi-transcriptomic mechanisms. These two mechanisms are possibly mediated by different Tet interactors in specific cell types and at different developmental stages.

description: Using 14M $ψ(2S)$ events accumulated by BESII at the BEPC, a Covariant Helicity Amplitude Analysis is performed for $ψ(2S)\toπ^+π^-J/ψ, J/ψ\to μ^+μ^-$. The $π^+π^-$ mass spectrum, distinctly different from phase space, suggests $σ$ production in this process. Two different theoretical schemes are used in the global fit to the data. The results are consistent with the existence of the $σ$. The $σ$ pole position is determined to be $(552^{+84}_{-106})-i(232^{+81}_{-72})$ MeV/$c^2$.

description: In the work presented here, the impact of magnetic field on the dynamical evolution of cometary globules Sim 129 and Sim 130 in Sh2-236 H\,II region and the ionized gas streaming out of their surfaces is investigated. The magnetic field morphology in the region associated with these globules is inferred using optical polarization measurements with the Sampurnanand Telescope at ARIES. The nebular emission is probed through radio continuum mapping at 1.4~GHz with the archival National Radio Astronomy Observatory (NRAO) very large array (VLA) Sky Survey (NVSS) data. The correlation of these measurements suggest that the photoevaporated gas from the surfaces of Sim 129 and Sim 130 is accumulated in clouds and starts streaming along the magnetic field lines. The $\rm ^{12}CO$ (J=1-0) molecular line observations are performed towards NGC\,1893 from 14-m single dish radio telescope in Taeduk Radio Astronomy Observatory (TRAO). The velocity dispersion in $\rm ^{12}CO$ (J=1-0) molecular line and the dispersion in polarization angles are used in Davis-Chandrasekhar-Fermi formulation to estimate the magnetic field strength towards two sim nebulae. The average value of field strength is found to be $\sim$60$μ$G with uncertainty of 0.5 times the estimated value.

Quantum Separability and Entanglement Detection via Entanglement-Witness Search and Global Optimization

description: We focus on determining the separability of an unknown bipartite quantum state $ρ$ by invoking a sufficiently large subset of all possible entanglement witnesses given the expected value of each element of a set of mutually orthogonal observables. We review the concept of an entanglement witness from the geometrical point of view and use this geometry to show that the set of separable states is not a polytope and to characterize the class of entanglement witnesses (observables) that detect entangled states on opposite sides of the set of separable states. All this serves to motivate a classical algorithm which, given the expected values of a subset of an orthogonal basis of observables of an otherwise unknown quantum state, searches for an entanglement witness in the span of the subset of observables. The idea of such an algorithm, which is an efficient reduction of the quantum separability problem to a global optimization problem, was introduced in PRA 70 060303(R), where it was shown to be an improvement on the naive approach for the quantum separability problem (exhaustive search for a decomposition of the given state into a convex combination of separable states). The last section of the paper discusses in more generality such algorithms, which, in our case, assume a subroutine that computes the global maximum of a real function of several variables. Despite this, we anticipate that such algorithms will perform sufficiently well on small instances that they will render a feasible test for separability in some cases of interest (e.g. in 3-by-3 dimensional systems).

description: The mysterious very high energy gamma-ray source, TeV J2032+4130, is coincident with the powerful Cygnus OB2 stellar association, though a physical association between the two remains uncertain. It is possible that the detected very high energy photons are produced via an overdensity of locally accelerated cosmic rays impinging on molecular clouds in the source region. In order to test this hypothesis, we used the Kitt Peak 12m, the Heinrich-Hertz Submillimeter Telescope (HH-SMT), and the Five College Radio Astronomy Observatory (FCRAO), to obtain observations in the J=1-->0 and J=2-->1 lines of both 12CO and 13CO. We report here on the detection of significant molecular material toward the TeV source region which could be acting as the target of locally accelerated CRs. We also find evidence of compact molecular clumps, showing large line widths in the CO spectra, possibly indicative of energetic processes in this region of Cygnus OB2.

description: We discuss the effect of a single diagonal defect on both the static and dynamical properties of entanglement in a spin chain. We show that entanglement localizes at the defect and discuss its localization length, arguing that this can be used as a mean to store entanglement. We also show that the impurity site can behave as an entanglement mirror and characterize the bouncing process in terms of reflection and transmission coefficients.

description: Due to their characteristic temperature and density, loop structures in active regions (ARs) can be seen bright in extreme ultraviolet (EUV) and soft X-ray images. The semiempirical determination of the three-dimensional (3D) distribution of basic physical parameters (electronic density and temperature, and magnetic field) is a key constraint for coronal heating models. In this work we develop a technique for the study of EUV bright loops based on differential emission measure (DEM) analysis and we first apply it to AR structures observed by the {Atmospheric Imaging Assembly} (AIA) on board the {Solar Dynamics Observatory} (SDO). The 3D structure and intensity of the magnetic field of the observed EUV loops are modelled using force-free field extrapolations based on magnetograms taken by the {Helioseismic and Magnetic Imager} (HMI) on board SDO. In this work we report the results obtained for several bright loops identified in different ARs. Our analysis indicates that the mean and width of the temperature distributions are nearly invariant along the loop lengths. For a particular loop we study its temporal evolution and find that these characteristics remain approximately constant for most of its life time. The appearance and disappearance of this loop occurs at time-scales much shorter than its life time of $\approx 2.5$ hours. The results of this analysis are compared with numerical simulations using the zero-dimensional (0D) hydrodynamic model, Enthalpy-Based Thermal Evolution of Loops (EBTEL). We study two alternative heating scenarios: first, we apply a constant heating rate assuming loops in quasi-static equilibrium, and second, we heat the loops using impulsive events or nanoflares. We find that all the observed loops are overdense with respect to a quasi-static equilibrium solution and that the nanoflare heating better reproduces the observed densities and temperatures.

description: Cette these cherche a analyser le contenu litteraire de La Princesse de Montpensier et de La Princesse de Cleves de Madame de Lafayette en fonction de leur valeur comme des documents qui refletent le contexte socio-historique de leur epoque. Ainsi, on reconnait chez l'auteur la qualite de temoin astucieux qui imbue ses ecrits d'elements importants contribuant a une meilleure appreciation de la condition feminine au dix-septieme siecle. L'auteur de ces deux romans met au point le genre du roman historique afin de l'employer comme canevas sur lequel elle impose sa vision perspicace des elements sociaux qui influencent plusieurs aspects de la vie de la femme noble depuis sa jeunesse jusqu'ci sa mort. Afin de profiter de cette structure, ce travail s'organise en trois chapitres suivant la chronologie de cette vie. Commengant avec les representations de l'education de la jeune fille, on passe a sa formation visee au mariage et a une analyse detaillee du statut de la femme mariee. Finalement, on abdrde la question du statut de la veuve. En considerant tous ces elements a la lumiere des ecrits critiques et historiques qui ont paru pendant trois siecles, on ressort une richesse de renseignements portant sur les exigences d'ordre moral et pratique qui delerminent la quality du statut de la femme au dix-septieme siecle. Les observations evoquees par Madame de Lafayette nous aident a preciser les influences, les transformations, les conflits et surtout les contradictions et les paradoxes qui parcourent la vie de la femme noble pendant l'age classique.

description: We propose an experiment to probe the unconventional quantum statistics of quasi-particles in fractional quantum Hall states by measurement of current noise. The geometry we consider is that of a Hall bar where two quantum point contacts introduce two interfering amplitudes for back-scattering. Thermal fluctuations of the number of quasi-particles enclosed between the two point contacts introduce current noise, which reflects the statistics of the quasi-particles. We analyze abelian $ν=1/q$ states and the non-abelian $ν=5/2$ state.

description: We consider the dynamics of a rigid filament in a motor protein assay under external loading. The motor proteins are modeled as active harmonic linkers with tail ends immobilized on a substrate. Their heads attach to the filament stochastically to extend along it, resulting in a force on the filament, before detaching. The rate of extension and detachment are load dependent. Here we formulate and characterize the governing dynamics in the mean field approximation using linear stability analysis, and direct numerical simulations of the motor proteins and filament. Under constant loading, the system shows transition from a stable configuration to instability towards detachment of the filament from motor proteins. Under elastic loading, we find emergence of stable limit cycle oscillations via a supercritical Hopf bifurcation with change in activity and the number of motor proteins. Numerical simulations of the system for large number of motor proteins show good agreement with the mean field predictions.
