description: We present a self-consistent numerical approach to solve the Gutzwiller variational problem for general multi-band models with arbitrary on-site interaction. The proposed method generalizes and improves the procedure derived by Deng et al., Phys. Rev. B. 79 075114 (2009), overcoming the restriction to density-density interaction without increasing the complexity of the computational algorithm. Our approach drastically reduces the problem of the high-dimensional Gutzwiller minimization by mapping it to a minimization only in the variational density matrix, in the spirit of the Levy and Lieb formulation of DFT. For fixed density the Gutzwiller renormalization matrix is determined as a fixpoint of a proper functional, whose evaluation only requires ground-state calculations of matrices defined in the Gutzwiller variational space. Furthermore, the proposed method is able to account for the symmetries of the variational function in a controlled way, reducing the number of variational parameters. After a detailed description of the method we present calculations for multi-band Hubbard models with full (rotationally invariant) Hund's rule on-site interaction. Our analysis shows that the numerical algorithm is very efficient, stable and easy to implement. For these reasons this method is particularly suitable for first principle studies -- e.g., in combination with DFT -- of many complex real materials, where the full intra-atomic interaction is important to obtain correct results.

Methods for improved imaging and analysis of tissue-based biomarkers
Creators: name: Khojasteh-Lakelayeh, Mehrnoush
Publisher: name: University of British Columbia
Year: 2012

description: Study of molecular biomarkers can provide insight into the molecular complexity of cancer, create new cancer screening tools, monitor treatment’s effectiveness, and predict patient’s response to treatment. This thesis proposes novel methods for the improved quantitative analysis of labeled molecular biomarkers in tissue sections. This is a necessary step towards the ultimate goal of personalized treatment of cancer. As 85% of all cancers arise in epithelial tissue, we have developed means for objectively and quantitatively assessing the distribution of a molecular biomarker in epithelial tissue sections. We have applied this means to characterize the spatial distribution of proliferating cells in 613 normal and pre-neoplastic bronchial epithelial biopsies. We have demonstrated, for the first time ever, that the knowledge of the spatial distribution of proliferating cells enables prediction of the outcome of lung intraepithelial lesions. We have developed methods for the automated and quantitative assessment of the expression of tissue-based molecular biomarkers on a cell-by-cell basis. This is achieved by multispectral imaging of labeled tissue sections. We have proposed methods for unsupervised linear spectral unmixing of multispectral images for the purpose of identifying individual labels in a multiple labeled tissue section. We have demonstrated that the use of multispectral imaging combined with our proposed analysis methods quantitatively improves the results of cell nuclei identification compared to three-color RGB imaging, in more than 22,000 cells in 58 tissue sections with nuclear, cytoplasmic, or membrane bound biomarkers. Finally, we have developed an imaging method for capturing images representing biomarkers in a tissue. Compared to multispectral imaging, our proposed imaging method significantly reduces the number of captured images required for the identification of a biomarker in a tissue. This method uses images captured under a series of narrow-band illumination spectra φ_i,i=1,2,…,N to find a weighted linear combination of the images that represents a certain component in a tissue. The weights in the weighted linear combination of images are then used to design one or two illumination spectra as weighted linear combinations of the narrow-band spectra φ_i. Images representing the component of interest are then captured under the designed illuminations.

An action research study on dynamic sight translation as a pedagogical tool for skill development and transfer in simultaneous interpreting teaching

subject: Other education not elsewhere classified

description: Sight translation (ST) is a common didactic tool in simultaneous interpreting (SI) teaching but there is only limited research on systemic usage of ST and expansion of its current pedagogical roles in skill acquisition. This research therefore is conducted to fill such a pedagogical gap. Based on Moser's (1978) information processing model, Giles's effort model and cognitive theories of skill acquisition, shared cognitive stages and skill components in SI and ST are discussed as the basis upon which a new ST variant, the so called dynamic sight translating (DST) is designed and further the effects of the new variant integrated into different forms of DST-related exercises for SI skill acquisition are discussed.
 The findings show that appropriate use of DST-related exercises can contribute to the skill development and transfer in SI training, which requires measured yet flexible manipulations of variables to accommodate students' skill levels and learning needs. Nevertheless, their intrinsic limitation calls for complementary use of other exercise components in SI to achieve a synergy of skill development. Meanwhile, the findings also have proved R is an effective methodological approach to explore pedagogical issues in a way that is personal, holistic,locally relevant and mutually stimulating to both teacher-researchers and students.

description: The development of post-Holocaust culture is coming to be understood as a transition between two regimes of memory. An initial period of repression gave way, after twenty years or more, to one of obsession. Before he turns to a careful discussion of the second of these regimes in international context, Omer Bartov deals with the first only briefly and then in largely negative and summary terms. In this short comment, I want to try to complicate this somewhat undifferentiated account of the first twenty years after the war. The period is critical, I suggest, because it may offer some important resources for escaping the vicious circle of enemies and victims that Bartov identifies.

description: We investigate how making highly consequential, highly undesirable decisions affects emotions and preference for autonomy. We examine individuals facing real or hypothetical decisions to discontinue their infants' life support who either choose personally or have physicians choose for them. Findings from a multidisciplinary approach consisting of a qualitative analysis of in-depth interviews and three laboratory studies reveal that perceived personal causality for making tragic decisions generates more negative feelings than having the same choices externally made. Tragic decisions also undermine coping abilities, weakening the desire for autonomy. Consequently, participants disliked making decisions but also resented relinquishing their option to choose.

description: Ob in den Tarifverhandlungen oder der Debatte über den Fachkräftemangel: Die Arbeitszeiten der Beschäftigten in Deutschland werden derzeit kontrovers diskutiert. Unterschiedliche Seiten bringen eine Ausweitung oder auch eine Reduzierung der Arbeitszeit ins Spiel. Auf Grundlage von Daten des Sozio-oekonomischen Panels wirft die vorliegende Untersuchung einen detaillierten Blick auf die Entwicklung der Arbeitszeiten seit der Wiedervereinigung. Die Analyse zeigt, dass die durchschnittlichen wöchentlichen Arbeitszeiten der Beschäftigten zwar gesunken sind, das Gesamtarbeitsvolumen aber gleichzeitig stieg und 2023 seinen bisherigen Höhepunkt von 55 Milliarden Stunden erreicht hat. Insbesondere für Mütter ist es noch immer schwierig, Familie und Beruf zu vereinbaren. Das führt dazu, dass Frauen häufig weniger arbeiten, als sie gerne würden. Mit Blick auf den hohen Fachkräftebedarf sollten politische Maßnahmen darauf abzielen, Frauen stärker bei der Ausweitung ihrer Arbeitszeiten zu unterstützen.

description: We report the design, synthesis and characterization of a novel molecular beacon (MB-FB) which uses the fluorescent bases (FB) 2-aminopurine (AP) and pyrrolo-dC (P-dC) as fluorophores. Because the quantum yield of these FB depend on hybridization with complementary target, the fluorescent properties of MB-FB were tuned by placing the FB site specifically within the MB such that hybridization with complementary sequence switches from single strand to double strand for AP and vice versa for P-dC. The MB-FB produces a ratiometric fluorescence increase (the fluorescence emission of P-dC over that of AP in the presence and absence of complementary sequence) of 8.5 when excited at 310 nm, the maximum absorption of AP. This ratiometric fluorescence is increased to 14 by further optimizing excitation (325 nm). The fluorescence lifetime is also affected by the addition of target, producing a change in the long-lived component from 6.5 to 8.7 ns (Exc. 310 nm, Em. 450 nm). Thermal denaturation profiles monitored at 450 nm (P-dC emission) show a cooperative denaturation of the MB-FB with a melting temperature of 53°C. The thermal denaturation profile of MB-FB hybridized with its target shows a marked fluorescence reduction at 53°C, consistent with a transition from double stranded helix to random coil DNA.

description: A new model of quantum computation is considered, in which the connections between gates are programmed by the state of a quantum register. This new model of computation is shown to be more powerful than the usual quantum computation, e. g. in achieving the programmability of permutations of N different unitary channels with 1 use instead of N uses per channel. For this task, a new elemental resource is needed, the "quantum switch", which can be programmed to switch the order of two channels with a single use of each one.

description: It is shown that the extended Hubbard Hamiltonian describing atoms confined in an optical lattice always contains commonly neglected terms which can significantly change the dynamical properties of the system. Particularly for bosonic systems, they can be exploited for creating orbital states on demand via the parametric resonance phenomenon. This indicates an additional application for optical lattices, namely the study and emulation of interactions between particles and lattice vibrations.

description: In this article, the application of 10 new amino-m-terphenyls in 3D-VAT printing was described. New compounds have specially designed D-π-A structure, where the central phenyl ring with nitrile and amino groups is the acceptor and the modifiable amino group is donor. Such design eliminates problem with acid scavenging and guaranteed desire properties and photoactivity as well as it allows further development of such system for 3D-VAT printing. Efficient excitation with intramolecular charge transfer provides excellent absorption and electrochemical properties, which can be tuned by modification of the amino group. The design allows photoinitiation of free radical, hybrid and especially cationic polymerisation even at 455 nm with more than 70% of monomer conversion. Such properties allow to use the developed compounds as efficient visible light photoinitiators for 3D printing of nanocomposite materials. The terphenyls can efficiently cure resins containing CuO and Al2O3 nano additives leading to high-resolution 3D prints.

description: We report the design, synthesis, and characterization of a molecular beacon (MB) consisting of two fluorescent dyes (Alexa 488 and RedX) for DNA and RNA analysis. In the absence of the target DNA or RNA the MB is in its stem-closed form and shows efficient energy transfer from the donor (Alexa) to the acceptor (RedX), generating mostly fluorescence from RedX. In the presence of the complementary target DNA the MB opened efficiently, hybridizes with the target DNA, and energy transfer is blocked in the stem-open form. This attachment to the target generates a fluorescence signature, which is clearly distinguishable from the fluorescence signature of the stem-closed form, allowing for ratiometric analysis of the fluorescence signal. In addition to steady-state fluorescence analysis, time resolved fluorescence (ps time range) and fluorescence depolarization studies were performed. We show that fluorescence lifetime and fluorescence depolarization measurements are useful analytical tools to optimize the MB design.

description: Alloy design coupled with metal additive manufacturing (AM) opens many opportunities for materials innovation. Investigating the effect of printing parameters for alloy design is essential to achieve good part quality. Among different factors, laser absorptivity, heat diffusivity, and in situ intermetallic phase formations are critical. In this study, the first step employed was a reduction in Al and V contents in Ti6Al4 V to design Ti3Al2 V alloy, and further 10 wt.% tantalum (Ta) and 3 wt.% copper (Cu) were added to Ti3Al2 V. A synergistic effect of Ta and Cu addition in Ti3Al2 V negated their effect with higher porosities in Ti3Al2V-Ta-Cu. Ti3Al2V-Ta composition was more sensitive to the laser power, whereas Ti3Al2V-Ta-Cu to the overall energy density. Understanding the effect of energy density on these alloys’ microstructural evolution and mechanical properties highlights the need for process-property optimisation during alloy design using AM.

description: We establish continuity of the integral representation y(t)=x(t)+∫0th(y(s)) ds, t≥0, mapping a function x into a function y when the underlying function space D is endowed with the Skorohod M1 topology. We apply this integral representation with the continuous mapping theorem to establish heavy-traffic stochastic-process limits for many-server queueing models when the limit process has jumps unmatched in the converging processes as can occur with bursty arrival processes or service interruptions. The proof of M1-continuity is based on a new characterization of the M1 convergence, in which the time portions of the parametric representations are absolutely continuous with respect to Lebesgue measure, and the derivatives are uniformly bounded and converge in L1.

description: Hohe und unsichere Stromkosten werden von der deutschen Wirtschaft als große Herausforderungen angesehen. Über einen Erneuerbare-Energien-Pool (EE-Pool) könnten derartige Preisrisiken mittelfristig abgesichert werden. Im Poolkonzept werden die günstigen Konditionen wettbewerblicher Ausschreibungen für neue Windkraft- und Solarprojekte an die Stromverbraucher*innen weitergegeben. Die Strompreise der Kund*innen werden so für den Anteil ihres Verbrauchs abgesichert, der dem Erzeugungsprofil des Pools entspricht. Dadurch werden die Anreize gestärkt in Flexibilität zu investieren, beispielweise in Wärmespeicher oder Batterien, um so den Strombedarf an die Wind- und Solarerzeugung anzupassen. Zudem bietet der Pool eine Referenz, um an Terminmärkten neue Produkte zur Absicherung von Flexibilität zu handeln. Neben den Vorteilen für Stromverbraucher*innen adressiert der Pool auch Finanzierungsrisiken für Projektentwickler erneuerbarer Energien und senkt damit deren Finanzierungskosten. So kann der Ausbau der Windkraft- und Solarenergie gefördert werden. Der EE-Pool trägt dazu bei, dass erneuerbare Energie noch besser zur Energieversorgung genutzt werden und das Stromsystem auf eine Welt mit einem hohen Anteil erneuerbarer Energien vorbereitet wird.

description: Measurements from the CMS experiment at the LHC of dihadron correlations for charged particles produced in PbPb collisions at a nucleon-nucleon centre-of-mass energy of 2.76 TeV are presented. The results are reported as a function of the particle transverse momenta (pt) and collision centrality over a broad range in relative pseudorapidity [Delta(eta)] and the full range of relative azimuthal angle [Delta(phi)]. The observed two-dimensional correlation structure in Delta(eta) and Delta(phi) is characterised by a narrow peak at (Delta(eta), Delta(phi)) approximately (0, 0) from jet-like correlations and a long-range structure that persists up to at least |Delta(eta)| = 4. An enhancement of the magnitude of the short-range jet peak is observed with increasing centrality, especially for particles of pt around 1-2 GeV/c. The long-range azimuthal dihadron correlations are extensively studied using a Fourier decomposition analysis. The extracted Fourier coefficients are found to factorise into a product of single-particle azimuthal anisotropies up to pt approximately 3-3.5 GeV/c for at least one particle from each pair, except for the second-order harmonics in the most central PbPb events. Various orders of the single-particle azimuthal anisotropy harmonics are extracted for associated particle pt of 1-3 GeV/c, as a function of the trigger particle pt up to 20 GeV/c and over the full centrality range.

description: Large and deterministic 3D structures with nanoscale features and porosities are valuable for various applications but are challenging to print due to the proximity effects that lead to the merging of adjacently printed features. Here, this challenge has been overcome by minimising the proximity effects in projection two-photon lithography (P-TPL), which is a high-throughput photopolymerization-based 3D printing technique. Through empirical studies and physics-based computational models, it is demonstrated that the proximity effects arise from distinct optical and chemical sources. Processing conditions that individually minimise these sources have been identified. These insights have been leveraged to generate an interspersing P-TPL technique capable of rapidly printing 3D structures with features smaller than 300 nm, pores finer than 700 nm, and at rates greater than 0.5 mm2/s per layer. As interspersing P-TPL is up to 50 times faster than conventional point-scanning TPL, it can enable the scalable printing of nanoporous 3D structures.

description: The Casimir effect between metal surfaces has now been well-verified at the few-percent level experimentally. However, the temperature dependence has never been observed in the laboratory, since all experiments are conducted at room temperature. The temperature dependence for the related Casimir-Polder force between an atom and a bulk material has, in contrast, been observed between a BEC and a silica substrate, with the environment and the silica held at different temperatures. There is a controversy about the temperature dependence for the force between metals, having to do with the magnitude of the linear temperature term for both low and high temperature, the latter being most prominent at large distances. There are also related anomalies pertaining to semiconductors. The status of this controversy, and of the relevant experiments, are reviewed in this report.

description: Masked stereolithography printing can be used to produce functionalised magneto-responsive polymer structures. Magnetic filler additivation of the photopolymer enables the production of powerful and fast soft robotics. However, current approaches require high filler concentrations, reducing the mechanical properties and compromising the processability. In this study, FeNi nanoparticles were added to a photopolymer to take advantage of their soft magnetic response and high magnetisation. Field-assisted printing gives rise to magnetic anisotropy by arranging laser-synthesised FeNi nanoparticles into uniaxial magnetic strands of up to 500 μm length. Favoured by the small size and even distribution of the nanoparticles, only 0.02 wt% are needed to detect magnetic responsivity. Thus, the impact on the mechanical property is reduced while facilitating the control over the composite magnetic properties. The practical feasibility of the composites is demonstrated by actuating gripper and impeller structures which offer possibilities in applications like drug delivery and tissue engineering.
Measurement of the electron charge asymmetry in inclusive W production in pp collisions at sqrt(s) = 7 TeV

description: A measurement of the electron charge asymmetry in inclusive pp to W + X to e nu + X production at sqrt(s) = 7 TeV is presented based on data recorded by the CMS detector at the LHC and corresponding to an integrated luminosity of 840 inverse picobarns. The electron charge asymmetry reflects the unequal production of positive and negative W bosons in pp collisions. The electron charge asymmetry is measured in bins of absolute value of electron pseudorapidity in the range of abs(eta) < 2.4. The asymmetry rises from about 0.1 to 0.2 as a function of the pseudorapidity and is measured with a relative precision better than 7%. This measurement provides new stringent constraints for parton distribution functions.

description: We have performed rigorous quantum five-dimensional (5D) calculations of the translation-rotation (T-R) energy levels and wave functions of H2, HD, and D2 inside C60. This work is an extension of our earlier investigation of the quantum T-R dynamics of H2@C60 [M. Xu et al., J. Chem. Phys. 128, 011101 (2008)] and uses the same computational methodology. Two 5D intermolecular potential energy surfaces (PESs) were employed, differing considerably in their well depths and the degree of confinement of the hydrogen molecule. Our calculations revealed pronounced sensitivity of the endohedral T-R dynamics to the differences in the interaction potentials, and to the large variations in the masses and the rotational constants of H2, HD, and D2. The T-R levels vary significantly in their energies and ordering on the two PESs, as well as from one isotopomer to another. Nevertheless, they all display the same distinctive patterns of degeneracies, which can be qualitatively understood and assigned in terms the model which combines the isotropic three-dimensional harmonic oscillator, the rigid rotor, and the coupling between the orbital and the rotational angular momenta of H2/HD/D2. The quantum number j associated with the rotation of H2, HD, and D2 was found to be a good quantum number for H2 and D2 on both PESs, while most of the T-R levels of HD exhibit strong mixing of two or more rotational basis functions with different j values.

description: A model for electroweak unification of quarks and leptons, in a gauge group $SU_{C}(3)\times SU(4)\times U_{X}(1)$ is constructed. The model requires, three generations of quarks and leptons which are replicas (mirror) of the standard quarks and leptons. The gauge group $SU(4)\times U_{X}(1)$ is broken in such a way so as to reproduce standard model and to generate heavy masses for the vector bosons ($W^{\pm}_{R_μ}$, $Z^{\prime}_μ$,$Z^{\prime\prime}_μ$), the leptoquarks and mirror fermions. It is shown lower limit on mass scale of mirror fermions is $m_{E}\geq\frac{m_{Z}}{2}$, $E^{-}$ being the lightest mirror fermion coupled to Z boson. As the universe expands, the heavy matter is decoupled at an early stage of expansion and may be a source of dark matter. Leptoquarks in the model connect the standard model and mirror fermions. Baryon genesis in our Universe implies antibaryon genesis in mirror Universe.

Eine Rekommunalisierung führt demnach nicht unbedingt zu einer Beschleunigung der Stilllegung, und diese bleibt in den bisherigen Wärmeplänen unberücksichtigt. Außerdem erschwert der derzeitige, auf Kosteneffizienz und Anschlusspflicht ausgerichtete Regulierungsrahmen die Stilllegung. Die Kommunen haben zudem einen finanziellen Anreiz, aus dem Gasgeschäft weiterhin Einnahmen zu erzielen – auch weil alternative Einnahmequellen fehlen, um die öffentliche Daseinsvorsorge zu finanzieren. Notwendig sind daher Anpassungen in der Regulierung sowie weitere Unterstützung der Kommunen durch Bund und Länder, um die Teilstilllegung der Erdgasinfrastruktur zu organisieren.

description: Direct excitation at 1064 nm and detection of singlet molecular oxygen at 1270 nm is made possible by the availability of powerful YAG-lasers and sensitive NIR photomultipliers. Singlet oxygen was generated in condensed phase at 77 K by direct excitation at 1064 nm (without the use of sensitizers). Several luminescing species were observed by time resolved luminescence spectroscopy and luminescence lifetime measurements, including the single molecule 1Δgand 1Σg+states as well as luminescence from the [1Δg]2 simultaneous transition. As an application we propose a novel method for obtaining quantitative non-intrusive mapping of the 2-D oxygen concentrations and pressure at cryogenic temperatures, which is of importance in aircraft design for high altitudes.

description: Training for 5 hours made the learning index of H3K23A overexpression group at the similar level to the H3WT group. A courtship learning experiment was conducted to value the learning levels after training 5 hours. Each male fly was allowed to train for 5 hours as the method described. The learning index of courtship was the time spent during the final 10 min vs. the initial 10 min. Unpaired t-test was used for statistics. Error bars represent the standard error of the mean; the number of samples was indicated in the bar. n.s., not significant. p=0.1379. (DOCX 50 kb)

description: Blaiseus chiapasensis Douglas, new species (Figs. 9, 18) Material examined. Three males. Etymology. The name of this and of all new species in this article refers to the type locality of the species. Type material. Holotype: Male labeled: ‘‘Ocozocoautla, Chis./ MEX.2.VIII.69/ L.A. Kelton’ ’; [red] ‘‘ HOLOTYPE / Blaiseus / chiapasensis/ Douglas 2006,’’ with genitalia in microvial attached to pin (CNCI). Paratypes: 2 males labeled: ‘‘ MEXICO: Chiapas,/ 12 mi. n. Ocozocoautla / July 8, 1971 / Clark, Murray,/ Hart, Schaffner’’ and ‘‘ MEXICO: Chiapas / 11 mi. n. Ocozocoautla/ July 19, 1973 / Mastro & Schaffner,’’ both with the following paratype designation labels [yellow] ‘‘ PARATYPE / Blaiseus / chiapasensis/ Douglas 2007’’ (TAMU). Type locality: Mexico, Chiapas, Ocozocoautla, approximately (16.92 ° N, 93.37 ° W). Diagnosis. Pterothorax: Elytra with apex upturned (including suture).

Integument without lighter coloured patches on elytra (Fig. 9). Head: Antennae reaching metacoxae; labrum concave in lateral view; nasale with circular pits antero-mesad of antennal fossae. Prothorax: Hypomeron with hind edge sinuate immediately meso-ventrad of hind angles. Prosternum with ventral surface of prosternal process surface not carinate laterally. Pterothorax: Scutellum with posterior apex rounded. Elytra with apex upturned (including suture), posterior surface flattened (Fig. 16); interval 5 costate; epipleurae with globular serrations posteriorly. Legs: Protibiae without teeth at midlength or apex (Fig. 6), (fossorial); tarsomere 4 with small ventral lobe. Male genitalia: Aedeagus with median lobe broadest near base, weakly concave at apex; parameres with free part of dorsal (setose) apices 1/4 length of ventral apices (Fig. 18), ventral apices curved laterad; inner apices present but unsclerotized. Female: Unknown. Comments. Males of this species most resemble B. guatemalensis new species. They differ from that species in that the median lobe of the aedeagus is broadest at the base and not the apex and in the length of the ventral lobes of the parameres, which are longer and curved laterad. Known from only the type locality and a site about 1 km to the south, elevation 750–1,000 m. This is the only Blaiseus species known from southern Mexico.

description: For decades, the Democrats have been viewed as the party of the poor, with the Republicans representing the rich. Recent presidential elections, however, have shown a reverse pattern, with Democrats performing well in the richer blue states in the northeast and coasts, and Republicans dominating in the red states in the middle of the country and the south. Through multilevel modeling of individual-level survey data and county- and state-level demographic and electoral data, we reconcile these patterns. Furthermore, we find that income matters more in red America than in blue America. In poor states, rich people are much more likely than poor people to vote for the Republican presidential candidate, but in rich states (such as Connecticut), income has a very low correlation with vote preference.

Quantum discord and non-Markovianity of quantum dynamics

description: The problem of recognizing (non-)Markovianity of a quantum dynamics is revisited through analyzing quantum correlations. We argue that instantaneously-vanishing quantum discord provides a necessary and sufficient condition for Markovianity of a quantum map. This is used to introduce a measure of non-Markovianity. This measure, however, requires demanding knowledge about the system and the environment. By using a quantum correlation monogamy property and an ancillary system, we propose a simplified measure with less requirements. Non-Markovianity is thereby decided by quantum state tomography of the system and the ancilla.

Struggles with survey weighting and regression modeling

description: The general principles of Bayesian data analysis imply that models for survey responses should be constructed conditional on all variables that affect the probability of inclusion and nonresponse, which are also the variables used in survey weighting and clustering. However, such models can quickly become very complicated, with potentially thousands of poststratification cells. It is then a challenge to develop general families of multilevel probability models that yield reasonable Bayesian inferences. We discuss in the context of several ongoing public health and social surveys. This work is currently open-ended, and we conclude with thoughts on how research could proceed to solve these problems.
Universality and Scaling Behaviour of Injected Power in Elastic Turbulence in Worm-like Micellar Gel

description: We study the statistical properties of spatially averaged global injected power fluctuations for Taylor-Couette flow of a worm-like micellar gel formed by surfactant CTAT. At sufficiently high Weissenberg numbers (Wi) the shear rate and hence the injected power p(t) at a constant applied stress shows large irregular fluctuations in time. The nature of the probability distribution function (pdf) of p(t) and the power-law decay of its power spectrum are very similar to that observed in recent studies of elastic turbulence for polymer solutions. Remarkably, these non-Gaussian pdfs can be well described by an universal large deviation functional form given by the Generalized Gumbel (GG) distribution observed in the context of spatially averaged global measures in diverse classes of highly correlated systems. We show by in-situ rheology and polarized light scattering experiments that in the elastic turbulent regime the flow is spatially smooth but random in time, in agreement with a recent hypothesis for elastic turbulence.
