description: We study, by using a wavelet decomposition methodology, the solar signature on global surface temperature data using the ACRIM total solar irradiance satellite composite by Willson and Mordvinov. These data present a +0.047%/decade trend between minima during solar cycles 21-23 (1980-2002). We estimate that the ACRIM upward trend might have minimally contributed $\sim$10-30% of the global surface temperature warming over the period 1980-2002.
Fractal Structures in Multidimensional Integer Arrays Generated by Multivariate Homogeneous Linear Recurrence Relations

subject: Mathematical sciences

description: The integer entries of Pascal’s triangle, when color-coded according to whether they are even or odd, produce a discrete version of the Sierpinski triangle fractal. We can think of this an example of a connection between a “local” phenomenon — the well-known recurrence relation for binomial coefficients, the entries of Pascal’s triangle, allows these entries to be described entirely in terms of nearby entries — and a “global” phenomenon, in which the color-coding modulo 2 produces patterns of arbitrarily large scale. The fractal nature of the global phenomenon mean that this pattern is particularly visually compelling, exhibiting a distinctive feature called “self-similarity” in which aspects of the pattern repeat across infinitely many scales.In this document we explain and explore the connection between these locally operating multidimensional recurrence relations and the global fractal patterns that result. Specifically, we show that for a certain class of multivariate homogeneous linear recurrence relations, their arrangement of nonzero residues modulo a prime always generates a fractal pattern. We call these functions “Delannoy-like” after the case of the Delannoy numbers, a two-dimensional array which modulo 3 produces another celebrated fractal, the Sierpinski carpet. Our approach is number-theoretic and combinatoric in nature, first by focusing on how these functions count lattice paths and thus obey a general formula, and then showing how this formula embodies the “Lucas property.” This property, which relates the value of a function modulo any prime p to the base-p expansions of its arguments turns out to be the key to establishing the correspondence between recurrence relations and fractals.We also explore compellingly similar phenomena beyond the strict premises of our main result, illustrating fractal-like behavior in the residues of such functions with respect to non-prime moduli or of functions which are not Delannoy-like.

description: We prove second and fourth order improved Poincaré type inequalities on the hyperbolic space involving Hardy-type remainder terms. Since theirs l.h.s. only involve the radial part of the gradient or of the laplacian, they can be seen as stronger versions of the classical Poincaré inequality. We show that such inequalities hold true on model manifolds as well, under suitable curvature assumptions and sharpness of some constants is also discussed.

RXTE and BeppoSAX Observations of MCG -5-23-16: Reflection From Distant Cold Material

description: We examine the spectral variability of the Seyfert 1.9 galaxy MCG -5-23-16 using RXTE and BeppoSAX observations spanning 2 years from April 1996 to April 1998. During the first year the X-ray source brightens by a factor of ~25% on timescales of days to months. During this time, the reprocessed continuum emission seen with RXTE does not respond measurably to the continuum increase. However, by the end of the second year during the BeppoSAX epoch the X-ray source has faded again. This time, the reprocessed emission has also faded, indicating that the reprocessed flux has responded to the continuum. If these effects are caused by time delays due to the distance between the X-ray source and the reprocessing region, we derive a light crossing time of between ~1 light day and ~1.5 light years. This corresponds to a distance of 0.001 pc to 0.55 pc, which implies that the reprocessed emission originates between 3x10^15 cm and 1.6x10^18 cm from the X-ray source. In other words, the reprocessing in MCG -5-23-16 is not dominated by the inner regions of a standard accretion disk.

description: Multi-focus image fusion, a technique to generate an all-in-focus image from two or more partially-focused source images, can benefit many computer vision tasks. However, currently there is no large and realistic dataset to perform convincing evaluation and comparison of algorithms in multi-focus image fusion. Moreover, it is difficult to train a deep neural network for multi-focus image fusion without a suitable dataset. In this letter, we introduce a large and realistic multi-focus dataset called Real-MFF, which contains 710 pairs of source images with corresponding ground truth images. The dataset is generated by light field images, and both the source images and the ground truth images are realistic. To serve as both a well-established benchmark for existing multi-focus image fusion algorithms and an appropriate training dataset for future development of deep-learning-based methods, the dataset contains a variety of scenes, including buildings, plants, humans, shopping malls, squares and so on. We also evaluate 10 typical multi-focus algorithms on this dataset for the purpose of illustration.

description: The bcc-based Fe_{1-x}Al_{x} exhibit interesting magnetic and anomalous structural properties as a function of composition and sample processing conditions arising from thermal or off-stoichiometric chemical disorder, and, although well studied, these properties are not understood. In stoichiometric B2 FeAl, including the effects of partial long-range order (i.e., thermal antisites), we find the observed paramagnetic response (with non-zero local moments), in contrast to past investigations which find ferromagnetism based on local density approximation (LDA) to density functional theory or which find a non-magnetic state from LDA+U, both of which are inconsistent with experiment. Moreover, from this magneto-chemical coupling, we are able to determine the origins of the lattice constant anomalies found in Fe_{1-x}Al_{x} for x=25-50, as observed from various processing conditions.

“NO ORDINARY FEELINGS”: MORMON WOMEN’S POLITICAL ACTIVISM, 1870–1920
Creators: name: Kitterman, Katherine
Publisher: name: American University
Year: 2023

description: This dissertation explores the rhetoric and strategies Mormon women employed in their efforts to defend and secure suffrage in the 19th and 20th centuries. Women citizens in Utah Territory became the first in the United States to cast ballots under an equal suffrage law in 1870. Their votes immediately attracted national scrutiny, enmeshing their suffrage rights in the national conflict over the Mormon practice of polygamy. They entered the suffrage movement to defend their voting rights against Congressional legislation and to support the push for a federal suffrage amendment. From indignation meetings and petitioning to printing a newspaper and lobbying public officials, Mormon women’s activism shaped and was shaped by the evolving national struggle for women’s voting rights over the next 50 years. Because Utah women’s voting rights were entangled in the conflict over Mormon polygamy from the beginning, their contributions and connections to the national suffrage movement have been obscured in public memory. This dissertation weaves this early and important part of the suffrage story back into the narrative, showing where Utah women’s experiences and choices fit into national trends and where they do not. Mormon women’s newspaper, petitions, diaries, and female Relief Society records reveal the politically astute strategies they employed to mobilize local organizations and build connections with open-minded suffragists in the east. Neither pawns nor militants, they drew on established patterns of women’s political engagement to speak in their own behalf, claim the rights and privileges of citizenship, and push for a federal women’s suffrage amendment. They also pioneered a new era of women in politics after Utah statehood in 1896. Telling their story from their perspective reframes U.S. suffrage history to include the women who pioneered the vote and first countered anti-suffrage arguments with their own experience.
The Milky Way's rotation curve with superfluid dark matter

description: Recent studies have shown that dark matter with a superfluid phase in which phonons mediate a long-distance force gives rise to the phenomenologically well-established regularities of Modified Newtonian Dynamics (MOND). Superfluid dark matter, therefore, has emerged as a promising explanation for astrophysical observations by combining the benefits of both particle dark matter and MOND, or its relativistic completions, respectively. We here investigate whether superfluid dark matter can reproduce the observed Milky Way rotation curve for $ R < 25\,\rm{kpc}$ and are able to answer this question in the affirmative. Our analysis demonstrates that superfluid dark matter fits the data well with parameters in reasonable ranges. The most notable difference between superfluid dark matter and MOND is that superfluid dark matter requires about $ 20\% $ less total baryonic mass (with a suitable interpolation function). The total baryonic mass is then $5.96 \cdot 10^{10}\,M_\odot$, of which $1.03\cdot10^{10}\,M_\odot$ are from the bulge, $3.95\cdot10^{10}\,M_\odot$ are from the stellar disk, and $0.98\cdot10^{10}\,M_\odot$ are from the gas disk. Our analysis further allows us to estimate the radius of the Milky Way's superfluid core (concretely, the so-called NFW and thermal radii) and the total mass of dark matter in both the superfluid and the normal phase. By varying the boundary conditions of the superfluid to give virial masses $M_{200}^{\rm{DM}}$ in the range $0.5-3.0\cdot10^{12}\,M_\odot$, we find that the NFW radius $R_{\rm{NFW}}$ varies between $65\,\rm{kpc}$ and $73\,\rm{kpc}$, while the thermal radius $R_T$ varies between about $67\,\rm{kpc}$ and $105\,\rm{kpc}$. This is the first such treatment of a non-spherically-symmetric system in superfluid dark matter.

description: We present a detailed investigation of the wave vector dependence of collective atomic motion in Au49Cu26.9Si16.3Ag5.5Pd2.3 and Pd42.5Cu27Ni9.5P21 supercooled liquids close to the glass transition temperature. Using x-ray photon correlation spectroscopy in a precedent uncovered spatial range of only few interatomic distances, we show that the microscopic structural relaxation process follows in phase the structure with a marked slowing down at the main average inter-particle distance. This behavior is accompanied by dramatic changes in the shape of the intermediate scattering functions which suggest the presence of large dynamical heterogeneities at length-scales corresponding to few particle diameters. A ballistic-like mechanism of particle motion seems to govern the structural relaxation of the two systems in the highly viscous phase, likely associated to hopping of caged particles in agreement with theoretical studies.
Field-induced gap in ordered Heisenberg antiferromagnets

description: Heisenberg antiferromagnets in a strong uniform magnetic field $H$ are expected to exhibit a gapless phase with a global O(2) symmetry. In many real magnets, a small energy gap is induced by additional interactions that can be viewed as a staggered transverse magnetic field $h = c H$, where $c$ is a small proportionality constant. We study the effects of such a perturbation, particularly for magnets with long-range order, by using several complimentary approaches: numerical diagonalizations of a model with long-range interactions, classical equations of motion, and scaling arguments. In an ordered state at zero temperature, the energy gap at first grows as $(cH)^{1/2}$ and then may dip to a smaller value, of order $(cH)^{2/3}$, at the quantum critical point separating the ``gapless'' phase from the gapped state with saturated magnetization. In one spatial dimension, the latter exponent changes to 4/5.

NSR picture changing operators have an elegant super-geometrical interpretation. In this paper we provide a generalization of this super-geometrical construction, which is also applicable to the pure spinor formalism.

description: Using Einstein, Landau-Lifshitz, Papapetrou and Weinberg energy-momentum complexes we explicitly evaluate the energy and momentum distributions associated with a non-static and circularly symmetric three-dimensional spacetime. The gravitational background under study is an exact solution of the Einstein's equations in the presence of a cosmological constant and a null fluid. It can be regarded as the three-dimensional analogue of the Vaidya metric and represents a non-static spinless (2+1)-dimensional black hole with an outflux of null radiation. All four above-mentioned prescriptions give exactly the same energy and momentum distributions for the specific black hole background. Therefore, the results obtained here provide evidence in support of the claim that for a given gravitational background, different energy-momentum complexes can give identical results in three dimensions. Furthermore, in the limit of zero cosmological constant the results presented here reproduce the results obtained by Virbhadra who utilized the Landau-Lifshitz energy-momentum complex for the same (2+1)-dimensional black hole background in the absence of a cosmological constant.

description: Hadronic vacuum polarization (HVP) is not only a critical part of the Standard Model (SM) prediction for the anomalous magnetic moment of the muon $(g-2)_μ$, but also a crucial ingredient for global fits to electroweak (EW) precision observables due to its contribution to the running of the fine-structure constant encoded in $Δα^{(5)}_\text{had}$. We find that with modern EW precision data, including the measurement of the Higgs mass, the global fit alone provides a competitive, independent determination of $Δα^{(5)}_\text{had}\big|_\text{EW}=270.2(3.0)\times 10^{-4}$. This value actually lies below the range derived from $e^+e^-\to\text{hadrons}$ cross-section data, and thus goes into the opposite direction as would be required if a change in HVP were to bring the SM prediction for $(g-2)_μ$ into agreement with the Brookhaven measurement. Depending on the energy where the bulk of the changes in the cross section occurs, reconciling experiment and SM prediction for $(g-2)_μ$ by adjusting HVP would thus not necessarily weaken the case for physics beyond the SM (BSM), but to some extent shift it from $(g-2)_μ$ to the EW fit. We briefly explore some options of BSM scenarios that could conceivably explain the ensuing tension.

FAITH RINGGOLD’S SLAVE RAPE STORY QUILT: STITCHING THE HISTORIES OF ENSLAVED AFRICAN AMERICAN WOMEN
Creators: name: Kalfaian, Eva E.
Publisher: name: American University
Year: 2023

description: Faith Ringgold is known for narrative quilts focusing on issues of gender and race in popular culture and art history. But one of her earliest works, and the subject of this thesis, is Slave Rape Story Quilt (1985), which addresses the history of slavery through three media—none of which, at first glance, immediately registers this subject. The top, or face, of the quilt’s surface is comprised of tie dye patches of fabric made by quiltmaker Marquetta Johnson. A large off-white cross shape occupies over half of the quilt and is comprised of both graphic and written elements. The black and white aquatint line etching at the center of the cross depicts an amalgamation of abstracted figures while the text occupying each branch of the cross tells the story of an enslaved woman named Beata. This thesis explores how and why Ringgold addresses slavery by way of these three media. Focusing on the central portion of the quilt, I consider the relationship between the narrative text and the relatively abstract imagery. I argue that the central image, the abstracted aquatint line etching, and the narrative story on Slave Rape Story Quilt work together to provide a first-hand account of the emotional and physical trauma of slavery. While the image evokes the emotional realities of the transatlantic slave trade, the story on the quilt explicitly addresses the physical trauma inflicted upon enslaved women. The text of the quilt does this by describing the gruesome rape of both Beata and her mother, leaving little to the imagination about the horrors enslaved women experienced. Although the tie dye portion of the quilt may seem out of place in relation to a work about enslavement and rape, I contend that it speaks to African arts, crafts, and textile traditions. By looking to and evoking African textile styles and techniques, Ringgold reconnects Beata with her ancestral homeland and also works to mend and repair the trauma and damage of enslavement. Slave Rape Story Quilt thus revises the history of enslavement to include the experiences, perspectives, and techniques of African American women. In the final quarter of the twentieth century, when popular culture was revisiting the history of slavery, Ringgold used this quilt to insert women back into the historical record.
On the derivation of power-law distributions within classical statistical mechanics far from the thermodynamic limit

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We show that within classical statistical mechanics without taking the thermodynamic limit, the most general Boltzmann factor for the canonical ensemble is a q-exponential function. The only assumption here is that microcanonical distributions have to be separable from of the total system energy, which is the prerequisite for any sensible measurement. We derive that all separable distributions are parametrized by a mathematical separation constant Q which can be related to the non-extensivity q-parameter in Tsallis distributions. We further demonstrate that nature fixes the separation constant Q to 1 for large dimensionality of Gibbs Gamma-phase space. Our results will be relevant for systems with a low-dimensional Gamma-space, for example nanosystems, comprised of a small number of particles or for systems with a dimensionally collapsed phase space, which might be the case for a large class of complex systems.

description: In quest of light harvesting systems, the interaction of a dithiolato-bisimino zinc complex, {2,6-bis(2-mercapto-3,5-ditert-butylphenylaminomethyl)pyridine zinc(II)} (DBZ) and 1,4,8,11,18,22,25-octabutoxy-29H,31H-phthalocyanine (Pc) has been investigated by steady-state absorption and fluorescence, as well as time resolved fluorescence techniques in both polar and nonpolar solvents. In nonpolar solvent, the fluorescence of the singlet DBZ (at 390 nm) was heavily quenched accompanied with formation of the singlet state of Pc (at 777 nm), indicating the occurrence of energy transfer from the singlet DBZ to populate the singlet Pc. Based on the fluorescence lifetime measurements of DBZ in the absence and presence of Pc, the rate constant (kENT) and quantum yield (ΦENT) of energy transfer were found to be 2.63 × 108 s−1 and 0.47, respectively. By exciting the Pc entity in the presence of DBZ, electron transfer takes place from the electron donating Pc to the electron accepting DBZ in polar acetonitrile. The observed thermodynamic parameters suggest the spontaneity of the binding for DBZ to Pc and the key interacting forces may involve hydrogen bonds, van der Waals forces and π-π stacking. The results suggest that the electron transfer via the singlet Pc is thermodynamically feasible. The difference in behavior in both solvents can therefore be ascribed to the difference in polarity and the nucleophilic character of the solvent, i.e. the donor strength of the coordinated solvent.

Although the tie dye portion of the quilt may seem out of place in relation to a work about enslavement and rape, I contend that it speaks to African arts, crafts, and textile traditions. By looking to and evoking African textile styles and techniques, Ringgold reconnects Beata with her ancestral homeland and also works to mend and repair the trauma and damage of enslavement. Slave Rape Story Quilt thus revises the history of enslavement to include the experiences, perspectives, and techniques of African American women. In the final quarter of the twentieth century, when popular culture was revisiting the history of slavery, Ringgold used this quilt to insert women back into the historical record.

description: The histopathological images contain a huge amount of information, which can make diagnosis an extremely timeconsuming and tedious task. In this study, we developed a completely automated system to detect regions of interest (ROIs) in whole slide images (WSI) of renal cell carcinoma (RCC), to reduce time analysis and assist pathologists in making more accurate decisions. The proposed approach is based on an efficient texture descriptor named dominant rotated local binary pattern (DRLBP) and color transformation to reveal and exploit the immense texture variability at the microscopic high magnifications level. Thereby, the DRLBPs retain the structural information and utilize the magnitude values in a local neighborhood for more discriminative power. For the classification of the relevant ROIs, feature extraction of WSIs patches was performed on the color channels separately to form the histograms. Next, we used the most frequently occurring patterns as a feature selection step to discard non-informative features. The performances of different classifiers on a set of 1800 kidney cancer patches originating from 12 whole slide images were compared and evaluated. Furthermore, the small size of the image dataset allows to investigate deep learning approach based on transfer learning for image patches classification by using deep features and fine-tuning methods. High recognition accuracy was obtained and the classifiers are efficient, the best precision result was 99.17% achieved with SVM. Moreover, transfer learning models perform well with comparable performance, and the highest precision using ResNet-50 reached 98.50%. The proposed approach results revealed a very efficient image classification and demonstrated efficacy in identifying ROIs. This study presents an automatic system to detect regions of interest relevant to the diagnosis of kidney cancer in whole slide histopathology images.

description: We study the onset of symmetry breaking after hybrid inflation in a model having the field content of the SU(2) gauge-scalar sector of the standard model, coupled to a singlet inflaton. This process is studied in (3+1)-dimensions in a fully non-perturbative way with the help of lattice techniques within the classical approximation. We focus on the role played by gauge fields and, in particular, on the generation of Chern-Simons number. Our results are shown to be insensitive to the various cut-offs introduced in our numerical approach. The spectra preserves a large hierarchy between long and short-wavelength modes during the whole period of symmetry breaking and Chern-Simons generation, confirming that the dynamics is driven by the low momentum sector of the theory. We establish that the Chern-Simons production mechanism is associated with local sphaleron-like structures. The corresponding sphaleron rates are of order 10^{-5} m^4, which, within certain scenarios of electroweak baryogenesis and a (not unnaturally large) additional source of CP violation, could explain the present baryon asymmetry of the universe.

description: We classify 5d N=1 gauge theories carrying a simple gauge group that can arise by mass-deforming 5d SCFTs and 6d SCFTs (compactified on a circle, possibly with a twist). For theories having a 6d UV completion, we determine the tensor branch data of the 6d SCFT and capture the twist in terms of the tensor branch data. We also determine the dualities between these 5d gauge theories, thus determining the sets of gauge theories having a common UV completion.

description: In vivo detection of neurotransmitters is a difficult process, but such detection offers vital data to tracking a patient’s progress through certain therapies. Using carbon fiber microelectrodes (CFMEs) has been verified as a cost-effective method to detect neurotransmitters for both in vivo and in vitro experimentation. However, bare CFMEs have some limitations as they are not sensitive enough to detect trace amounts of dopamine such as those found in a Parkinson’s Disease patient’s brain. Therefore, a more sensitive method is needed. It has been shown that gold nanoparticles (AuNPs) can be deposited onto CFMEs to enhance the detection sensitivity. However, only preliminary studies have been performed up to now and this can be further explored. In addition to spherical gold nanoparticles (AuNPs), a number of different shapes and sizes of AuNPs can be synthesized. Shapes such as cubes, octahedrons, rhombic dodecahedrons, rods, spheres, and prisms can enhance the sensitivity of detection in different ratios across various neurotransmitter metabolites by changing the surface of the sensor. The purpose of this research is to use shape-specific AuNPs modified CFMEs (AuNPs-CFMEs) to detect neurotransmitters, such as dopamine. We hypothesize that not only the chemical composition of the coating, but also the shape and surface roughness, can enhance neurochemical deposition. For this study, we have focused on preparing CFMEs coated with cubic, octahedral, and rhombic dodecahedral (RD) AuNPs. Nanoparticles are deposited onto the CFMEs using specific techniques. We plan to find the effect of specific AuNP morphologies, sizes, and uniformity on CFME sensitivity and detection using fast scan cyclic voltammetry (FSCV). Future considerations begin with the synthesis of other morphologies, such as nanorods, nano prisms, and nanospheres. Dopamine analogues, such as tyrosine, can also be considered as an aim for detection in the future.

description: We use a functional integral formalism developed earlier for the pure Luttinger liquid (LL) to find an exact representation for the electron Green function of the LL in the presence of a single backscattering impurity. This allows us to reproduce results (well known from the bosonization techniques) for the suppression of the electron local density of states (LDoS) at the position of the impurity and for the Friedel oscillations at finite temperature. In addition, we have extracted from the exact representation an analytic dependence of LDoS on the distance from the impurity and shown how it crosses over to that for the pure LL.

description: Carbon fiber microelectrodes (CFMEs) have a vast range of applications in neurotransmitter detection. However, CFMEs have low conductivity and surface area, and the bare carbon fiber microelectrode will cause electrode fouling during neurotransmitter detection, thereby reducing the detection sensitivity. Due to the limitations of the CFMEs, in this experiment, various morphological gold nanoparticles (AuNPs) such as cubic, octahedral, and rhombic dodecahedral (RD) were modified on CFMEs. Shape-specific AuNPs modified CFMEs have a larger electroactive surface area and higher detection sensitivity than bare CFMEs. When using fast scan cyclic voltammetry (FSCV) to detect neurotransmitters such as dopamine, shape specific AuNPs can continuously detect dopamine at a lower detection limit than bare CFMEs and have higher sensitivity. This research is of great significance for enhancing neurotransmitters' detection (such as dopamine) in vivo and in vitro by carbon fiber electrodes. It is also essential for the research of drug abuse, depression, and neurodegenerative diseases.

description: In many developing countries, supermarkets are spreading rapidly at the expense of traditional food markets and shops. Changing retail environments and food choices may affect consumer diets and nutritional outcomes. Previous research suggested that supermarkets may contribute to rising rates of obesity. However, most existing research looked at adult populations. Here, we analyze effects of supermarkets on child nutrition with panel data from medium-sized towns in Kenya. Instrumental variable regressions show that supermarket food purchases significantly increase child height-for-age and weight-for age Z-scores. The effects on height are larger than the effects on weight. These are welcome findings, because child stunting continues to be a major nutrition problem in developing countries that is declining more slowly than child underweight. Supermarkets do not seem to be a driver of childhood obesity in Kenya. The positive effects of supermarkets on child nutrition are channeled through improvements in food variety and dietary quality.
