description: Unless there is evidence for fractal scaling with a single exponent over distances .1 <= r <= 100 h^-1 Mpc then the widely accepted notion of scale invariance of the correlation integral for .1 <= r <= 10 h^-1 Mpc must be questioned. The attempt to extract a scaling exponent νfrom the correlation integral n(r) by plotting log(n(r)) vs. log(r) is unreliable unless the underlying point set is approximately monofractal. The extraction of a spectrum of generalized dimensions ν_q from a plot of the correlation integral generating function G_n(q) by a similar procedure is probably an indication that G_n(q) does not scale at all. We explain these assertions after defining the term multifractal, mutually--inconsistent definitions having been confused together in the cosmology literature. Part of this confusion is traced to a misleading speculation made earlier in the dynamical systems theory literature, while other errors follow from confusing together entirely different definitions of ``multifractal'' from two different schools of thought. Most important are serious errors in data analysis that follow from taking for granted a largest term approximation that is inevitably advertised in the literature on both fractals and dynamical systems theory.

description: Half-metallic ferromagnets can produce fully spin-polarized conduction electrons and can be applied to fabricate spintronic devices. Thus, in this study, the electronic structure, magnetic properties, and optical properties of GaSb, which has exhibited half-metallicity, doped with Mn, a 3d transition metal, are calculated using the generalized gradient approximation and Heyd-Scuseria-Ernzerhof (HSE) functional. Ga$_{1-x}$Mn$_x$Sb ($x = 0.25, 0.5, 0.75$) materials exhibit ferromagnetic half-metallic properties and a high Curie temperature, indicating that this series can applied in spintronic devices. Meanwhile, they absorb strongly in the infrared band, suggesting that Ga$_{1-x}$Mn$_{x}$Sb also has potential applications in infrared photoelectric devices.

description: Iterative phase retrieval algorithms typically employ projections onto constraint subspaces to recover the unknown phases in the Fourier transform of an image, or, in the case of x-ray crystallography, the electron density of a molecule. For a general class of algorithms, where the basic iteration is specified by the difference map, solutions are associated with fixed points of the map, the attractive character of which determines the effectiveness of the algorithm. The behavior of the difference map near fixed points is controlled by the relative orientation of the tangent spaces of the two constraint subspaces employed by the map. Since the dimensionalities involved are always large in practical applications, it is appropriate to use random matrix theory ideas to analyze the average-case convergence at fixed points. Optimal values of the gamma parameters of the difference map are found which differ somewhat from the values previously obtained on the assumption of orthogonal tangent spaces.

Publisher: name: Columbia University
Year: 2011
Subjects: Chemistry, Physical and theoretical

description: This thesis harnesses the environmental sensitivity of the dark states of molecular fluorophores, both endogeneous in cells/tissue and externally introduced for mapping of chemical micro-environments including factors such as ion concentration and microviscosity. A novel technique for directly detecting the dynamics and population of dark states, such as the lowest triplet state, was developed and called FAPA, Fluorescence Anomalous Phase Advance. This technique is a sensitive and fast reporter of dark state dynamics and can be used for imaging. In addition, a genetically-encoded microviscosity and micro-environmental mapping ability with high protein-specific specificity was developed by using a TMP-tag and Fluorescence Lifetime Imaging.

description: Group-III-nitride semiconductors (GaN, InGaN, and AlGaN) are important for the fabrication of a range of optoelectronic devices (such as blue-green light emitting diodes, laser diodes, and UV detectors) as well as devices for high-temperature/high-power electronics. In the fabrication of these devices, ion bombardment represents a very attractive technological tool. However, a successful application of ion implantation depends on an understanding of the effects of radiation damage. Hence, this thesis explores a number of fundamental aspects of radiation effects in wurtzite III-nitrides. Emphasis is given to an understanding of (i) the evolution of defect structures in III-nitrides during ion irradiation and (ii) the influence of ion bombardment on structural, mechanical, optical, and electrical properties of these materials. ¶ ... ¶ The work presented in this thesis has resulted in the identification and understanding of a number of both fundamental and technologically important ion-beam processes in III-nitrides. Most of the phenomena investigated are related to the nature and effects of implantation damage, such as lattice amorphization, formation of planar defects, preferential surface disordering, porosity, decomposition, and quenching of CL. These effects are often technologically undesirable, and the work of this thesis has indicated, in some cases, how such effects can be minimized or controlled. However, the thesis has also investigated one example where irradiation-produced defects can be successfully applied for a technological benefit, namely for electrical isolation of GaN-based devices. Finally, results of this thesis will clearly stimulate further research both to probe some of the mechanisms for unusual ion-induced effects and also to develop processes to avoid or repair unwanted lattice damage produced by ion bombardment.

description: Abtrak

This research aims to reveal the prevention of fraud in village funds. One way that the government can use to mitigate the risk of fraud is by applying local wisdom and preventive efforts that need to be taken. Preventing fraud in managing village funds is very important to identify practices that are detrimental and undermine the integrity of the use of funds. The method used was a systematic literature review, and by reviewing 30 related journals, several preventions of village fund fraud in Indonesia were identified. Strengthening Ethics and Cultural Values, Building Community Awareness, Transparency and Accountability, Encouraging Collaboration between Interested Parties and Respecting Cultural Diversity, by utilizing Indonesian culture as a foundation, it is hoped that fraud prevention efforts can be more effective and sustainable, and create a fairer society, have integrity, and progress.

description: It is shown by Connes, Douglas and Schwarz that gauge theory on noncommutative torus describes compactifications of M-theory to tori with constant background three-form field. This indicates that noncommutative gauge theories on more general manifolds also can be useful in string theory. We discuss a framework to noncommutative quantum gauge theory on Poisson manifolds by using the deformation quantization. The Kontsevich formula for the star product was given originally in terms of the perturbation expansion and it leads to a non-renormalizable quantum field theory. We discuss the nonperturbative path integral formulation of Cattaneo and Felder as a possible approach to construction of noncommutative quantum gauge theory on Poisson manifolds. Some other aspects of classical and quantum noncommutative field theory are also discussed.

description: We study the stochastic heat equation in two spatial dimensions with a multiplicative white noise, as the limit of the equation driven by a noise that is mollified in space and white in time. As the mollification radius $ \varepsilon\to 0 $, we tune the coupling constant near the critical point, and show that the single time correlation functions converge to a limit written in terms of an explicit non-trivial semigroup. Our approach consists of two steps. First we show the convergence of the resolvent of the (tuned) two-dimensional delta Bose gas, by adapting the framework of Dimock and Rajeev (2004) to our setup of spatial mollification. Then we match this to the Laplace transform of our semigroup.

description: The electronic structures of S and Mo as well as the local coordination of Mo are investigated as a function of metal promotion Chevrel-phase (CP) sulfides. We observe the effect of metal promoter-induced electron donation into the stoichiometric range MxMo6S8 (M = Fe, Ni, Cu; x = 0–2) through analysis of X-ray absorption near-edge structure regions. We further observe the effect of this promotion on the bonding environment of Mo6 metal centers through extended X-ray absorption fine structure analysis. We monitor expansion and contraction of Mo6 octahedra with and without metal promotion, as has been predicted by Hückel molecular orbital theory. We further observe a marked tunability in the electronic structure of sulfur upon charge transfer between promoting species and Mo6S8 units. Average Mo6 octahedron Mo–Mo bond contraction from 2.76 Å to as short as 2.69 Å was observed upon incorporation of metal promoters, while intercluster separation displays a pronounced increase for promoter-host lattices compared to un-promoted Mo6S8. To corroborate spectroscopically observed phenomena, we performed computational analyses of spin-polarized densities of state for the CP materials investigated herein, where a detectable increase in sulfur-based frontier orbital population is observed in accordance with experimentally validated orbital filling.

description: Network analysis has become a well-recognized methodology in physics education research (PER), with study topics including student performance and persistence, faculty change, and the structure of conceptual networks. The social network analysis side of this work has focused on quantitative analysis of whole-network cases, such as the structure of networks in single classrooms. Egocentric or personal network approaches are largely unexplored, and qualitative methods are underdeveloped. In this paper, we outline theoretical and practical differences between two major network paradigms--whole-network and egocentric--and introduce theoretical frameworks and methodological considerations for egocentric studies. We also describe qualitative and mixed-methods approaches that are currently missing from the PER literature. We identify areas where these additional network methods may be of particular interest to physics education researchers, and end by discussing example cases and implications for new PER studies.

description: We study the final stages of the evolution of a binary system consisted of a black hole and a white dwarf star. We implement the quantum hydrodynamic equations and carry out numerical simulations. As a model of a white dwarf star, we consider a zero temperature droplet of attractively interacting degenerate atomic bosons and spin-polarized atomic fermions. Such mixtures are investigated experimentally nowadays. We find that the white dwarf star is stripped off its mass while passing the periastron. Due to nonlinear effects, the accretion disk originated from the white dwarf becomes fragmented and the onset of a quantum turbulence with giant quantized vortices present in the bosonic component of the accretion disk is observed. The binary system ends its life in a spectacular way, revealing quantum features underlying the white dwarf star's structure. We find a charged mass, falling onto a black hole, could be responsible for recently discovered ultraluminous X-ray bursts. The simulations show that the final passage of a white dwarf near a black hole can cause a gamma-ray burst.

description: This thesis presents a numerical exploration of the dynamics governing rotating flow driven by a surface stress in the " sliced cylinder " model of Pedlosky & Greenspan (1967) and Beardsley (1969), and its close relative, the " sliced cone " model introduced by Griffiths & Veronis (1997). The sliced cylinder model simulates the barotropic wind-driven circulation in a circular basin with vertical sidewalls, using a depth gradient to mimic the effects of a gradient in Coriolis parameter. In the sliced cone the vertical sidewalls are replaced by an azimuthally uniform slope around the perimeter of the basin to simulate a continental slope. Since these models can be implemented in the laboratory, their dynamics can be explored by a complementary interplay of analysis and numerical and laboratory experiments. ¶ In this thesis a derivation is presented of a generalised quasigeostrophic formulation which is valid for linear and moderately nonlinear barotropic flows over large-amplitude topography on an f-plane, yet retains the simplicity and conservation properties of the standard quasigeostrophic vorticity equation (which is valid only for small depth variations). This formulation is implemented in a numerical model based on a code developed by Page (1982) and Becker & Page (1990). ¶ ...

description: The non-detection of companion stars in Type Ia supernova (SN) progenitor systems lends support to the notion of double-degenerate (DD) systems and explosions triggered by the merging of two white dwarfs. This very asymmetric process should lead to a conspicuous polarimetric signature. By contrast, observations consistently find very low continuum polarization as the signatures from the explosion process largely dominate over the pre-explosion configuration within several days. Critical information about the interaction of the ejecta with a companion and any circumstellar matter is encoded in the early polarization spectra. In this study, we obtain spectropolarimetry of SN\,2018gv with the ESO Very Large Telescope at $-$13.6 days relative to the $B-$band maximum light, or $\sim$5 days after the estimated explosion --- the earliest spectropolarimetric observations to date of any Type Ia SN. These early observations still show a low continuum polarization ($\lesssim$0.2\%) and moderate line polarization (0.30$\pm$0.04\% for the prominent \ion{Si}{2} $λ$6355 feature and 0.85$\pm$0.04\% for the high-velocity Ca component). The high degree of spherical symmetry implied by the low line and continuum polarization at this early epoch is consistent with explosion models of delayed detonations and is inconsistent with the merger-induced explosion scenario. The dense UV and optical photometry and optical spectroscopy within the first $\sim$100 days after the maximum light indicate that SN\,2018gv is a normal Type Ia SN with similar spectrophotometric behavior to SN\,2011fe.

The Quite [sic] Revolution: An analysis of the change toward below-replacement-level fertility in Addis Ababa

description: Rural-urban differentials in fertility behaviour are neither new nor surprising, but a difference of over four children per woman as observed between rural Ethiopia and the country's national capital, Addis Ababa, in 1990 is rare, possibly unique. Reported fertility in Addis Ababa in 1990 was about 2.6 children per woman. By the mid-1990s, it declined further to 1.8 children per woman. This study investigates the dimensions, components and causes of this remarkable reproductive change. ¶ The study specifically asks and seeks to answer the following questions. Is the decline real, or is it merely an illusion created by faulty reporting? If it is real, how has it come about? Did it result from a change in the onset of reproduction or a decline in the proportion of women reaching high parities or both? And in what context has such a fundamental, even revolutionary, change taken place in a country and a continent that are mostly yet to join the global transition to a small family-size norm. ¶ Data for the study were drawn from two national population censuses, undertaken in 1984 and 1994, two fertility surveys, conducted in 1990 and 1995, and a number of supplementary sources, including a qualitative study conducted by the investigator. Results from the study confirm that the trend of declining fertility and the recent fall to below-replacement-level are indeed real. As the analysis shows the decline was largely driven by changes in the marriage pattern, and supplemented by the increased propensity of fertility control observed across all birth orders and age groups. All socio-economic groups in the city have had a decline in cohort fertility and this was brought about both by shifts in population composition (a composition effect) and increased intensity of fertility control within each group (a rate effect). The institutional and cultural factors that are believed to have prompted these changes are discussed in the thesis in some detail.

description: It has been experimentally observed that weakly conducting suspended films of smectic liquid crystals undergo electroconvection when subjected to a large enough potential difference. The resulting counter-rotating vortices form a very simple convection pattern and exhibit a variety of interesting nonlinear effects. The linear stability problem for this system has recently been solved. The convection mechanism, which involves charge separation at the free surfaces of the film, is applicable to any sufficiently two-dimensional fluid. In this paper, we derive an amplitude equation which describes the weakly nonlinear regime, by starting from the basic electrohydrodynamic equations. This regime has been the subject of several recent experimental studies. The lowest order amplitude equation we derive is of the Ginzburg-Landau form, and describes a forward bifurcation as is observed experimentally. The coefficients of the amplitude equation are calculated and compared with the values independently deduced from the linear stability calculation.

description: As defined by Guralnick and Saxl given a nonabelian simple group $S$ and its nonidentity automorphism $x$, a natural number $α_S(x)$ does not exceed a natural number $m$ if some $m$ conjugates of $x$ in the group $\langle x,S\rangle$ generate a subgroup that includes $S$. The outcome of this paper together with one by Di Martino, Pellegrini, and Zalesski, both of which are based on computer calculations with character tables, is a refinement of the estimates by Guralnick and Saxl on the value of $α_S(x)$ in the case where $S$ is a sporadic group. In particular, we prove that $α_S(x)\leqslant 4$, except when $S$ is one of the Fischer groups and $x$ is a $3$-transposition. In the latter case, $α_S(x)=6$ if $S$ is either $Fi_{22}$ or $Fi_{23}$ and $α_S(x)=5$ if $S={Fi_{24}}'$.

It’s fungus, its grow on sorghum seedling mainly affected by fluorescence (ovary). useful for blood clotting and bleeding. The experiment was to determine the effectiveness role on blood clotting and recovery of wound healing. Smut treated by Trichoderma Powder. The cultivation of this crop is challenged by different biotic and abiotic production constraints such as disease, insets pests, and moisture deficiency according to environment. the maturing fungal Fruiting Structures rupture and release the teliospores that infect sees on other plants. Only seedborne spores cause infection. Teliospores adhere to the surface of seeds where they overwinter. The sorghum smut (fungus) grow in monsoon season because the fungus in summer season under dormancy. They meet favorable condition so its again grow.

The dried powder sorghum smut obtained by sorghum plant. Its evaluation mainly on their Morphology, Appearance, PH determination, Solubility Microscopic evaluation. These are mainly soluble in organic solvents but insoluble in water sparingly soluble in alcohol .the smut basic in nature so due to its ancient time its treated by cow’s urine spread on crop. The smut powder find out the some anticoagulant character and clotting activating factor.

The pharmaceutical powder are used for a number of properties and aesthetic purposes, including recovery of new and old wound healing, Bleeding, rapidly clotting and any types of Cuts, wound, runny bleeding etc. The fungus powder  is not any harm to human health. The general population and society can safely employ these blood stop powder drug.

description: The third (Es3) member of the Eocene Shahejie Formation is the main hydrocarbon source rock interval in the Raoyang Sag of the Bohai Bay Basin. The lower Es3 (Es3L) and upper Es3 (Es3U) submembers display clear differences in source rock quality. The formation mechanisms of the source rocks are investigated via geochemical methods using 60 samples from three wells to reconstruct the paleo-environment during deposition. The major element parameters exhibit changes in paleoclimate from humid to arid. Indicators such as Sr/Ba, B/Ga, the gammacerane index and isotopic data suggest fresh–brackish and hydrological open lakes with unstable water column stratification likely occurred during deposition of the Es3L submember and saline and hydrologically closed lakes with stable water column stratification likely during deposition of the Es3U submember. Carbon isotope values of organic matter, trace elements and biomarker parameters suggest that the Es3L submember had moderate productivity, with a significant contribution from terrigenous organic matter whereas the Es3U submember had slightly enhanced productivity, with no or minor contributions from terrigenous organic matter. Furthermore, the pristane/phytane ratio and the enrichment of Mo and U indicate that the euxinic bottom-water conditions (sulfidic) of the lakes during deposition of the Es3U submember were best for preserving organic matter. Comparison of the models of source rock deposition of the Es3L and Es3U submembers indicates that the redox conditions play an important role in the formation of organic-rich source rocks in the Raoyang Sag.

description: Image partitioning, or segmentation without semantics, is the task of decomposing an image into distinct segments, or equivalently to detect closed contours. Most prior work either requires seeds, one per segment; or a threshold; or formulates the task as multicut / correlation clustering, an NP-hard problem. Here, we propose an efficient algorithm for graph partitioning, the "Mutex Watershed''. Unlike seeded watershed, the algorithm can accommodate not only attractive but also repulsive cues, allowing it to find a previously unspecified number of segments without the need for explicit seeds or a tunable threshold. We also prove that this simple algorithm solves to global optimality an objective function that is intimately related to the multicut / correlation clustering integer linear programming formulation. The algorithm is deterministic, very simple to implement, and has empirically linearithmic complexity. When presented with short-range attractive and long-range repulsive cues from a deep neural network, the Mutex Watershed gives the best results currently known for the competitive ISBI 2012 EM segmentation benchmark.

description: I calculate optimistically asymptotic behaviors of the WRT SU(2) invariants for the three-manifolds obtained from the figure-eight knot by p-surgeries with p=0,1,2,...,10, from which one can extract volumes and the Chern-Simons invariants of these closed manifolds. I conjecture that this also holds for general closed three-manifolds.

Farrell cohomology of low genus pure mapping class groups with punctures

description: In this paper, we calculate the p-torsion of the Farrell cohomology for low genus pure mapping class groups with punctures, where p is an odd prime. Here, `low genus' means g=1,2,3; and `pure mapping class groups with punctures' means the mapping class groups with any number of punctures, where the punctures are not allowed to be permuted. These calculations use our previous results about the periodicity of pure mapping class groups with punctures, as well as other cohomological tools. The low genus cases are interesting because we know that the high genus cases can be reduced to the low genus ones. Also, the cohomological properties of the mapping class groups without punctures are closely related to our cases.

Hexagonal patterns in finite domains

Publisher: name: arXiv
Year: 1997
Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: In many mathematical models for pattern formation, a regular hexagonal pattern is stable in an infinite region. However, laboratory and numerical experiments are carried out in finite domains, and this imposes certain constraints on the possible patterns. In finite rectangular domains, it is shown that a regular hexagonal pattern cannot occur if the aspect ratio is rational. In practice, it is found experimentally that in a rectangular region, patterns of irregular hexagons are often observed. This work analyses the geometry and dynamics of irregular hexagonal patterns. These patterns occur in two different symmetry types, either with a reflection symmetry, involving two wavenumbers, or without symmetry, involving three different wavenumbers. The relevant amplitude equations are studied to investigate the detailed bifurcation structure in each case. It is shown that hexagonal patterns can bifurcate subcritically either from the trivial solution or from a pattern of rolls. Numerical simulations of a model partial differential equation are also presented to illustrate the behaviour.

description: Adequate cell production for adoptive cell transfer therapies such as Chimeric Antigen Receptor (CAR)-T cell therapy remains a critical barrier to treatment for indications that fail to achieve clinical success. One such disease is Chronic Lymphocytic Leukemia (CLL), a B-cell lymphoma with their characteristically exhausted T cells, marked by a progressive loss of the ability to secrete cytokines and proliferate, as well as an increase in the expression of checkpoint inhibitor molecules such as PD-1. The goal of this thesis is to characterize the functional differences or specific biomarkers within the CLL patient population that is indicative of the proliferation outcomes. Conventional clinical markers such as Rai stage or PD-1 expression alone were inadequate to describe the complex variability among patients. In order to better characterize exhaustion using microscopy-based cell function assays, we developed a sample sparing microscopy chamber that requires as little as 1000 cells per sample. The microscopy chambers were mass produced via injection molding, and made compatible with the antibody microcontact printing technique developed in the Kam lab. The chambers typically reduced cell usage per experiment by 20-fold. This reduction allowed us to measure IL-2 secretion, T cell arrest response to activating antibody patterns (pattern alignment), and motility of scarce human samples simultaneously from a single experiment. Results from these functional readouts along with other clinical markers were used as inputs for a multifactor exploratory analysis to cluster patients according to their functional similarities from the combination of responses in an unbiased manner. The resulting clusters based on the combination of the top 3 parameters IL-2, pattern alignment, and PD-1 resulted in better separation of patient groups and provided a basis for predicting max doubling outcomes from these inputs. We further used motility measurements as a way to understand initial T cell response to activation before the stop response, which was measured as pattern alignment previously. The time it takes for cells to come to a stop at the signal was most informative for translating T cell activation response to a stop response, and eventually to downstream effector functions of cytokine secretion and proliferation. The results of this work provide a powerful framework to describe different donors, and can be applied to cells from additional donors to guide future cell expansion studies.

description: Stormwater biofilters have shown promising yet variable removal of faecal microorganisms. The effects of vegetation, filter media and extended drying on the removal of Escherichia coli are investigated in the current study. Semi-synthetic stormwater was applied to 25 biofilters representing five different design configurations, all of which contained a submerged zone (SZ). The influence of extended dry periods on E. coli removal depended on the presence/absence of vegetation. Uptake of SZ water by plants with extensive roots during the dry periods lead to deterioration of the subsequent outflow water quality compared to unvegetated biofilters. Without a significant loss of SZ volume, a loamy sand biofilter planted with either Carex appressa or Leptospermum continentale can achieve a higher removal performance than an unvegetated washed sand biofilter. However, in warmer climates that experience long dry weather periods, and inability to control SZ volumes, un-vegetated columns may result in lower effluent E. coli concentrations.
