description: Halide perovskites are strongly influenced by large amplitude anharmonic lattice fluctuations at room temperature. We develop a tight binding model for dynamically disordered MAPbI$_3$ based on density functional theory (DFT) calculations to calculate electronic structure for finite temperature crystal structures at the length scale of thermal disorder and carrier localization. The model predicts individual Hamiltonian matrix elements and band structures with high accuracy, owing to the inclusion of additional matrix elements and descriptors for non-Coulombic interactions. We apply this model to electronic structure at length and time scales inaccessible to first principles methods, finding an increase in band gap, carrier mass, and the sub-picosecond fluctuations in these quantities with increasing temperature as well as the onset of carrier localization in large supercells induced by thermal disorder at 300 K. We identify the length scale $L^*= 5$ nm as the onset of localization in the electronic structure, associated with associated with decreasing band edge fluctuations, increasing carrier mass, and Rashba splitting approaching zero.
Syntheses of chlorin, benzoporphyrin and bacteriochlorin derivatives

Publisher: name: University of British Columbia
Year: 2010

description: The syntheses of chlorin, benzoporphyrin, and bacteriochlorin derivatives are presented in this thesis. The key step in each synthesis involved a Diels-Alder reaction of a vinylporphyrin with an appropriate dienophile. The vinylporphyrins 81,101 and 106 were prepared in high yield using a variation of Johnson's regioselective synthesis employing dipyrromethenes 93,94,104, and 144 as crucial building blocks. As the first objective, the Diels-Alder reactions of 81 with 1,2-disubstituted vinyl sulfones were investigated in order to provide a route to chlorin derivatives which could act as intermediates in a proposed synthetic pathway for a model compound of factor 1. The regio-and stereoselectivity of the cycloadditions were examined and the appropriate regioisomers were considered for the continuation of the proposed synthetic plan. The second objective of the work was to provide a general strategy directed towards the synthesis of benzoporphyrin derivatives via a common intermediate, namely the β-unsubstituted-β'-vinylporphyrin 101. Evidence is presented that suggests an isomerization of the initial cycloadduct to another porphyrin en route to the benzoporphyrin 171. The final objective of the work was to synthesize stable bacteriochlorin derivatives to be used as photosensitizers in photodynamic therapy. The key intermediate, an A,C-divinylporphyrin 106, was synthesized via two routes, and its chemistry with olefinic and acetylenic dienophiles was studied. The resulting bis-adducts (e.g. 179 and 183) were isolated in moderate yields and were found to be stable compounds absorbing light in the 730-800 nm region.[See Thesis for Diagrams]

description: As in many other areas of science, systems biology makes extensive use of statistical association and significance estimates in contingency tables, a type of categorical data analysis known in this field as enrichment (also over-representation or enhancement) analysis. In spite of efforts to create probabilistic annotations, especially in the Gene Ontology context, or to deal with uncertainty in high throughput-based datasets, current enrichment methods largely ignore this probabilistic information since they are mainly based on variants of the Fisher Exact Test. We developed an open-source R package to deal with probabilistic categorical data analysis, ProbCD, that does not require a static contingency table. The contingency table for the enrichment problem is built using the expectation of a Bernoulli Scheme stochastic process given the categorization probabilities. An on-line interface was created to allow usage by non-programmers and is available at: http://xerad.systemsbiology.net/ProbCD/ . We present an analysis framework and software tools to address the issue of uncertainty in categorical data analysis. In particular, concerning the enrichment analysis, ProbCD can accommodate: (i) the stochastic nature of the high-throughput experimental techniques and (ii) probabilistic gene annotation.

Adaptive use of replicated Latin Hypercube Designs for computing Sobol' sensitivity indices

Year: 2021
Subjects: subject: Computation (stat.CO)

description: As recently pointed out in the field of Global Sensitivity Analysis (GSA) of computer simulations, the use of replicated Latin Hypercube Designs (rLHDs) is a cost-saving alternative to regular Monte Carlo sampling to estimate first-order Sobol' indices. Indeed, two rLHDs are sufficient to compute the whole set of those indices regardless of the number of input variables. This relies on a permutation trick which, however, only works within the class of estimators called Oracle 2. In the present paper, we show that rLHDs are still beneficial to another class of estimators, called Oracle 1, which often outperforms Oracle 2 for estimating small and moderate indices. Even though unlike Oracle 2 the computation cost of Oracle 1 depends on the input dimension, the permutation trick can be applied to construct an averaged (triple) Oracle 1 estimator whose great accuracy is presented on a numerical example. Thus, we promote an adaptive rLHDs-based Sobol' sensitivity analysis where the first stage is to compute the whole set of first-order indices by Oracle 2. If needed, the accuracy of small and moderate indices can then be reevaluated by the averaged Oracle 1 estimators. This strategy, cost-saving and guaranteeing the accuracy of estimates, is applied to a computer model from the nuclear field.

description: We present a simple and generic theoretical description of actin-based motility, where polymerization of filaments maintains propulsion. The dynamics is driven by polymerization kinetics at the filaments' free ends, crosslinking of the actin network, attachment and detachment of filaments to the obstacle interfaces and entropic forces. We show that spontaneous oscillations in the velocity emerge in a broad range of parameter values, and compare our findings with experiments.

Novel terpenoid metabolites from the marine sponge xestopongia vanilla
Creators: name: Northcote, Peter T.
Publisher: name: University of British Columbia
Year: 2010

description: A chemical study of the marine petrosid sponge Xestospongia vanilla has led to the isolation of nine new isoprene derived secondary metabolites. Their proposed structures were elucidated by a combination of spectroscopic analysis and chemical degradation and interconversions. Xestodiol (94), a C₁₈ apocarotenoid, appears to be a degradation product of the abundant marine carotenoid fucoxanthin (103). The xestovanins (98-102) are triterpene glycosides; their isolation represents the second reported occurrence of this type of compound from sponges. Their triterpene carbon skeletons are unique, and are either monocyclic (secoxestovanane skeleton) or bicyclic (xestovanane skeleton). All the xestovanins contain the same disaccharide fragment composed of L-rhamnose alpha linked to the 4 position of D-fucose. The fucose residue is beta linked to the same position on the aglycone in all isolated xestovanins. Xestovanin D (102) contains an extra L-rhamnose residue attached to a different position on the aglycone. Xestovanin A (98) was found to be an inhibitor of fungal growth, while xestovanin C (101) inhibited the growth of bacteria. A series of three smaller apparently related terpenes was also isolated. Xestenone (95) and secoxestenone (97) both contained new C₁₉ carbon skeletons. Secoxestenone (97), a monocyclic compound, could be converted into the bicyclic xestenone (95) by an intramolecular aldol condensation. The C₂₀ xestolide (96), with a similar structure to both xestenone and secoxestenone, had an unique carbon skeleton that could not be derived readily from an unrearranged diterpene skeleton. It is suggested that these three smaller terpenes (95-97) are degraded triterpenes, derived from a secoxestovanane carbon skeleton. The secondary metabolite chemistry of the petrosid sponges is reviewed, and an overview of triterpenes of marine origin is presented.
Cluster many-body expansion: a many-body expansion of the electron correlation energy about a cluster mean-field reference

description: The many-body expansion (MBE) is an efficient tool which has a long history of use for calculating interaction energies, binding energies, lattice energies, and so on. In the past, applications of MBE to correlation energy have been unfeasible for large systems, but recent improvements to computing resources have sparked renewed interest in capturing the correlation energy using the generalized $n$-th order Bethe-Goldstone equation. In this work, we extend this approach, originally proposed for a Slater determinant, to a tensor product state (TPS) based wavefunction. By partitioning the active space into smaller orbital clusters, our approach starts from a cluster mean field reference TPS configuration and includes the correlation contribution of the excited TPSs using the many-body expansion. This method, named cluster many-body expansion (cMBE), improves the convergence of MBE at lower orders compared to directly doing a block based MBE from a RHF reference. We present numerical results for strongly correlated systems such as the one- and two-dimensional Hubbard models and the chromium dimer. The performance of the cMBE method is also tested by partitioning the extended $π$ space of several large $π$-conjugated systems, including a graphene nano-sheet with a very large active space of 114 electrons in 114 orbitals, which would require $10^{66}$ determinants for the exact FCI solution.

We show how these types of path integrals can be evaluated and apply our results to study the thermodynamics of a minority stripe phase in a bulk membrane. The fluctuation induced contribution to the line tension between the stripe and the bulk phase is computed, as well as the effective interaction between the two phases in the tensionless case where the two phases have differing bending rigidities.

description: Klaus Kempter follows up his biographical sketch on long-time metalworker’s union chairman Eugen Loderer (1920–1995) with a reflection on Loderer’s being a member of the generation of the so-called “forty-fivers”, which has frequently been under the focus of attention in recent years. It becomes evident that – irrespective of its anti-capitalistic rhetoric and its reception by the public – IG Metall under Eugen Loderer practiced essentially pragmatic politics of representing labour interests, not unlike supposedly more conservative trade unions under the leadership of other “forty-fivers”. Loderer and his contemporaries, then, link to the older tradition of the  "Gewerkschaftsbeamten” and thus make the generation of determined socialists of the in-between years (Otto Brenner, Willi Bleicher, and others) appear as an exception in trade union history.

description: Driven by the idea of a future democratic socialist Germany, Ludwig Rosenberg (1903–1977), forced into exile in Britain by the National Socialists and later to become chairman of the German Federation of Trade Unions, returns in June 1945 to his destroyed homeland. On the basis of his experience of a functioning democracy and a strong institutionalised worker’s movement gained in exile, he wants to investigate the possibilities of establishing a German equivalent of the Workers’ Educational Association. After six months in post-war Germany, Rosenberg, who lost part of his family to the Nazis, realises that the Nazis were far less successful in instilling their ideology in the minds of the German people than leaving behind a moral indifference and complete ignorance.

description: All hydrodynamical simulations of turbulent astrophysical phenomena require sub-grid scale models to properly treat energy dissipation and metal mixing. We present the first implementation and application of an anisotropic eddy viscosity and metal mixing model in Lagrangian astrophysical simulations, including a dynamic procedure for the model parameter. We compare these two models directly to the common Smagorinsky and dynamic variant. Using the mesh-free finite mass method as an example, we show that the anisotropic model is best able to reproduce the proper Kolmogorov inertial range scaling in homogeneous, isotropic turbulence. Additionally, we provide a method to calibrate the metal mixing rate that ensures numerical convergence. In our first application to cosmological simulations, we find that all models strongly impact the early evolution of galaxies leading to differences in enrichment and thermodynamic histories. The anisotropic model has the strongest impact, with little difference between the dynamic and the constant-coefficient variant. We also find that the metal distribution functions in the circumgalactic gas are significantly tighter at all redshifts, with the anisotropic model providing the tightest distributions. This is contrary to a recent study that found metal mixing to be relatively unimportant on cosmological scales. In all of our experiments the constant-coefficient Smagorinsky and anisotropic models rivaled their dynamic counterparts, suggesting that the computationally inexpensive constant-coefficient models are viable alternatives in cosmological contexts.

For each prime ideal p of good reduction, let m_p(F,P) be the size of the F-orbit of the reduction of P modulo p. Fix any e > 0. We show that for almost all primes p, in the sense of analytic density, the orbit size m_p(F,P) is larger than (log(N(p)))^(1-e), where N(p) is the norm of the ideal p.

description: The elite of the German trade unions is characterised by a high continuity regarding the social profile of the leadership, the recruiting patterns and the position of power inside the organisations. Despite the political integration of the trade unions this elite remains an outsider in a socio-cultural manner. Nowadays the unions are standing at a crossroads. The conditions have changed fundamentally: a tremendous loss of members, a dwindling political influence, a declining loyalty of the works councils and a diminishing ability to mobilise the rank and file. This process, caused by the erosion of the cooperative industrial relations in the course of the transformation of global capitalism, also has an effect on the leadership. One can notice an external recruitment of some chairmen, a rising importance of the works council chairmen of the big companies, a growing distance to the traditional ally, the socialdemocratic party, but the outcome stays open.

description: By combining high-resolution (HST-WFPC2) and wide-field ground based (2.2m ESO-WFI) and space (GALEX) observations, we have collected a multi-wavelength photometric data base (ranging from the far UV to the near infrared) of the galactic globular cluster NGC1904 (M79). The sample covers the entire cluster extension, from the very central regions up to the tidal radius. In the present paper such a data set is used to study the BSS population and its radial distribution. A total number of 39 bright ($m_{218}\le 19.5$) BSS has been detected, and they have been found to be highly segregated in the cluster core. No significant upturn in the BSS frequency has been observed in the outskirts of NGC 1904, in contrast to other clusters (M 3, 47 Tuc, NGC 6752, M 5) studied with the same technique. Such evidences, coupled with the large radius of avoidance estimated for NGC 1904 ($r_{avoid}\sim 30$ core radii), indicate that the vast majority of the cluster heavy stars (binaries) has already sunk to the core. Accordingly, extensive dynamical simulations suggest that BSS formed by mass transfer activity in primordial binaries evolving in isolation in the cluster outskirts represent only a negligible (0--10%) fraction of the overall population.

How important are next-to-leading order models in predicting strange particle spectra in p+p collisions at STAR ?
Creators: name: Heinz, Mark
Publisher: name: arXiv
Year: 2007
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: STAR has measured a variety of strange particle species in p + p collisions at $\sqrt{s}$ = 200 GeV. These high statistics data are ideal for comparing to existing leading- and next-to-leading order perturbative QCD (pQCD) models. Next-to-leading (NLO) models have been successful in describing inclusive hadron production using parameterized fragmentation functions (FF) for quarks and gluons. However, in order to describe identied strange particle spectra at NLO, knowledge of flavor separated FF is essential. Such FF have recently been parameterized using data by the OPAL experiment and allow for the first time to perform NLO calculation for strange baryons. In fact, comparing the STAR Lambda data with these calculations allow to put a constraint on the gluon fragmentation function. We show that the Leading-order (LO) event generator PYTHIA has to be tuned significantly to reproduce the STAR identified strange particle data. In particular, it fails to describe the observed enhancement of baryon-to-meson ratio at intermediate pT (2-6 GeV/c). In heavy-ion (HI) collisions this observable has been extensively compared with models and shows a strong dependency on collision centrality or parton density. In the HI context the observed enhancement has been explained by recent approaches in terms of parton coalescense and recombination models.

description: We compare the star-forming properties of satellites around Milky Way (MW) analogs from the Stage~II release of the Satellites Around Galactic Analogs Survey (SAGA-II) to those from the APOSTLE and Auriga cosmological zoom-in simulation suites. We use archival GALEX UV imaging as a star-formation indicator for the SAGA-II sample and derive star-formation rates (SFRs) to compare with those from APOSTLE and Auriga. We compare our detection rates from the NUV and FUV bands to the SAGA-II H$α$ detections and find that they are broadly consistent with over $85\%$ of observed satellites detected in all three tracers. We apply the same spatial selection criteria used around SAGA-II hosts to select satellites around the MW-like hosts in APOSTLE and Auriga. We find very good overall agreement in the derived SFRs for the star-forming satellites as well as the number of star-forming satellites per host in observed and simulated samples. However, the number and fraction of quenched satellites in the SAGA-II sample are significantly lower than those in APOSTLE and Auriga below a stellar mass of $M_*\sim10^{8}\,M_{\odot}$, even when the SAGA-II incompleteness and interloper corrections are included. This discrepancy is robust with respect to the resolution of the simulations and persists when alternative star-formation tracers are employed. We posit that this disagreement is not readily explained by vagaries in the observed or simulated samples considered here, suggesting a genuine discrepancy that may inform the physics of satellite populations around MW analogs.

description: An analysis of 1,955 physics graduate students from 19 PhD programs shows that undergraduate grade point average predicts graduate grades and PhD completion more effectively than GRE scores. Students' undergraduate GPA (UGPA) and GRE Physics (GRE-P) scores are small but statistically significant predictors of graduate course grades, while GRE quantitative and GRE verbal scores are not. We also find that males and females score equally well in their graduate coursework despite a statistically significant 18 percentile point gap in median GRE-P scores between genders. A counterfactual mediation analysis demonstrates that among admission metrics tested only UGPA is a significant predictor of overall PhD completion, and that UGPA predicts PhD completion indirectly through graduate grades. Thus UGPA measures traits linked to graduate course grades, which in turn predict graduate completion. Although GRE-P scores are not significantly associated with PhD completion, our results suggest that any predictive effect they may have are also linked indirectly through graduate GPA. Overall our results indicate that among commonly used quantitative admissions metrics, UGPA offers the most insight into two important measures of graduate school success, while posing fewer concerns for equitable admissions practices.

In the present article the inversion spectrum of ${\rm{PH_3}}$ is considered with the help of the Schrödinger equation (SE) with position dependent mass and corresponding modified double-well potential. The SE is shown to be exactly solvable. The results are used for the analysis of the pertinent experimental data available in literature. We are based on the reliable value $ν_2=E_2-E_0=992.1\ {\rm cm^{-1}}$ ($2ν_2=E_4-E_0=1972.5\ {\rm cm^{-1}}$; $3ν_2=E_6-E_0=2940.8\ {\rm cm^{-1}}$; $4ν_2=E_8-E_0=3895.9\ {\rm cm^{-1}}$) obtained by \v Spirko et al. Also we use the value for the barrier height $E_b=12300 \ {\rm cm^{-1}}$ that seems to be commonly accepted at present and the hypothetical value for the energy splitting of the 11-th doublet of the $10ν_2$ band $s_{10}=E_{21}-E_{20}\approx 7.2\ {\rm cm^{-1}}$ suggested in the literature. Definite predictions are derived for the energy splitting of the 4-th doublet of the $3ν_2$ band $s_3=E_{7}-E_{6}$ that is a test one for the observation in the experiment of Okuda et al. SE with position dependent mass provides self-consistently the required values of $\{ν_2; E_b;s_{10}\}$ yielding $s_3= 6.21\cdot 10^{-12}\ {\rm cm^{-1}}$.

description: The phenomenology of the low scale U(1)_{B-L} extension of the standard model and its implications at LHC is presented. In this model, an extra gauge boson corresponding to B-L gauge symmetry and an extra SM singlet scalar (heavy Higgs) are predicted. We show a detailed analysis of both heavy and light Higgses decay and production in addition to the possible decay channels of the new gauge boson. We find that the cross sections of the SM-like Higgs production are reduced by ~ 20%-30%, while its decay branching ratios remain intact. The extra Higgs has relatively small cross sections and the branching ratios of Z'-> l^+ l^- are of order ~20% compared to ~ 3% of the SM resuls. Hence, the search for Z' is accessible via a clean dilepton signal at LHC.

description: Gravitationally lensed curved arcs provide a wealth of information about the underlying lensing distortions. Extracting precise lensing information from extended sources is a key component in many studies aiming to answer fundamental questions about the Universe. To maintain accuracy with increased precision, it is of vital importance to characterize and understand the impact of degeneracies inherent in lensing observables. In this work, we present a formalism to describe the gravitational lensing distortion effects resulting in curved extended arcs based on the eigenvectors and eigenvalues of the local lensing Jacobian and their directional differentials. We identify a non-local and non-linear extended deflector basis that inherits these local properties. Our parameterization is tightly linked to observable features in extended sources and allows one to accurately extract the lensing information of extended images without imposing an explicit global deflector model. We quantify what degeneracies can be broken based on specific assumptions on the local lensing nature and assumed intrinsic source shape. Our formalism is applicable from the weak linear regime, the semi-linear regime all the way up to the highly non-linear regime of highly magnified arcs of multiple images. The methodology and implementation presented in this work provides a framework to assessing systematics, to guide inference efforts in the right choices in complexity based on the data at hand, and to quantify the lensing information extracted in a model-independent way.

description: In the canonical formalism of statistical physics, a signature of a first order phase transition for finite systems is the bimodal distribution of an order parameter. Previous thermodynamical studies of nuclear sources produced in heavy-ion collisions provide information which support the existence of a phase transition in those finite nuclear systems. Some results suggest that the observable Z1 (charge of the biggest fragment) can be considered as a reliable order parameter of the transition. This talk will show how from peripheral collisions studied with the INDRA detector at GSI we can obtain this bimodal behaviour of Z1. Getting rid of the entrance channel effects and under the constraint of an equiprobable distribution of excitation energy (E*), we use the canonical description of a phase transition to link this bimodal behaviour with the residual convexity of the entropy. Theoretical (with and without phase transition) and experimental Z1-E* correlations are compared. This comparison allows us to rule out the case without transition. Moreover that quantitative comparison provides us with information about the coexistence region in the Z1-E* plane which is in good agreement with that obtained with the signal of abnormal uctuations of configurational energy (microcanonical negative heat capacity).

Entropy Multiparticle Correlation Expansion for a Crystal

description: As first shown by H. S. Green in 1952, the entropy of a classical fluid of identical particles can be written as a sum of many-particle contributions, each of them being a distinctive functional of all spatial distribution functions up to a given order. By revisiting the combinatorial derivation of the entropy formula, we argue that a similar correlation expansion holds for the entropy of a crystalline system. We discuss how one- and two-body entropies scale with the size of the crystal, and provide fresh numerical data to check the expectation, grounded on theoretical arguments, that both entropies are extensive quantities.

Group velocity of gravitational waves in an expanding universe

description: The group velocity of gravitational waves in a flat Friedman-Robertson-Walker universe is investigated. For plane waves with wavelength well inside the horizon, and a universe filled with an ideal fluid with the pressure to density ratio less than 1/3, the group velocity is greater than the velocity of light. As a result, a planar pulse of gravitational waves propagating through the universe during the matter/dark energy dominated era arrives to the observer with the peak shifted towards the forefront. For gravitational waves emitted by inspiralling supermassive black holes at the edge of the observable universe, the typical shift that remains after the effects of nonplanarity are suppressed is of order of ten picoseconds.

Influence of thermal fluctuations on active diffusion at large Péclet numbers

description: Wavelet Monte Carlo dynamics simulations are used to study the dynamics of passive particles in the presence of microswimmers, taking account of the often-omitted thermal motion alongside the hydrodynamic flows generated by the swimmers. Although the Péclet numbers considered are large, we find the thermal motion to have a significant effect on the dynamics of our passive particles, and can be included as a decorrelation factor in the velocity autocorrelation with a decay time proportional to the Péclet number. Similar decorrelation factors come from swimmer rotations, e.g.~run and tumble motion, and apply to both entrainment and far field loop contributions. These decorrelation factors lead to active diffusivity having a weak apparent power law close to $Pe^{0.2}$ for small tracer-like particles at Péclet numbers appropriate for E. coli swimmers at room temperature. Meanwhile, the reduced hydrodynamic response of large particles to nearby forces has a corresponding reduction in active diffusivity in that regime. Together, they lead to a non-monotonic dependence of active diffusivity on particle size that can shed light on similar behaviour observed in experiments by Patteson et al.

The main aspects of the state environmental policy of the Russian Federation Government and legal regulation over the past decade in the field of industrial enterprises’ business activities are analyzed. A role of the business sector and the state in the commencement of a global environmental modernization of the production in the modern Russian reality is determined. Further directions of the state policy in the field of environmental protection both at the federal and regional levels are predicted.

description: Using shear wave elastography, we measure the changes in the wave speed with the stress produced by a striated muscle during isometric voluntary contraction. To isolate the behaviour of an individual muscle from complementary or antagonistic actions of adjacent muscles, we select the flexor digiti minimi muscle, whose sole function is to extend the little finger. To link the wave speed to the stiffness, we develop an acousto-elastic theory for shear waves in homogeneous, transversely isotropic, incompressible solids subject to uniaxial stress. We then provide measurements of the apparent shear elastic modulus along, and transversely to, the fibre axis for six healthy human volunteers of different age and sex. The results display a great variety across the six subjects. We find that the slope of the apparent shear elastic modulus along the fibre direction changes inversely to the maximum voluntary contraction (MVC) produced by the volunteer. We propose an interpretation of our results by introducing the S (slow) or F (fast) nature of the fibres, which harden the muscle differently and accordingly, produce different MVCs. This work opens the way to measuring the elastic stiffness of muscles in patients with musculoskeletal disorders or neurodegenerative diseases.

description: High-temperature conventional superconductivity in hydrogen-rich materials under high pressure has been reportedly found in twelve different compounds in recent years. However, the experimental evidence on which these claims are based has recently been called into question. Here we discuss the measurement of trapped magnetic flux, that should establish definitively that these materials are indeed high-temperature superconductors. Its absence should confirm claims to the contrary.
