description: From 2000 through 2004, per-capita orange juice purchases decreased by 12.3 percent in the United States, while the popularity and media coverage of low-carbohydrate dieting exploded. Content analysis was used to count selected newspaper articles topically related to low-carbohydrate dieting, the Atkins diet, and the South Beach diet. These data were included in a national orange juice demand model, where purchase data served as the independent variable and proxy for consumer demand of orange juice. Results indicate that media coverage of low-carbohydrate diets and dieting was negatively and significantly related to demand for orange juice in the United States.
H-minimal graphs of low regularity in the Heisenberg group

Subjects: subject: Differential Geometry (math.DG)

description: In this paper we investigate H-minimal graphs of lower regularity. We show that noncharactersitic C^1 H-minimal graphs whose components of the unit horizontal Gauss map are in W^{1,1} are ruled surfaces with C^2 seed curves. In a different direction, we investigate ways in which patches of C^1 H-minimal graphs can be glued together to form continuous piecewise C^1 H-minimal surfaces. We apply these description of H-minimal graphs to the question of the existence of smooth solutions to the Dirichlet problem with smooth data. We find a necessary condition for the existence of smooth solutions and produce examples where the conditions are satisfied and where they fail. In particular we illustrate the failure of the smoothness of the data to force smoothness of the solution to the Dirichlet problem by producing a class of smooth curves whoses H-minimal spanning graphs cannot be C^2.

description: By confining water in nano-pores of silica glass, we can bypass the crystallization and study the pressure effect on the dynamical behavior in deeply supercooled state using neutron scattering. We observe a clear evidence of a cusp-like fragile-to-strong (F-S) dynamic transition. Here we show that the transition temperature decreases steadily with an increasing pressure, until it intersects the homogenous nucleation temperature line of bulk water at a pressure of 1600 bar. Above this pressure, it is no longer possible to discern the characteristic feature of the F-S transition. Identification of this end point with the possible second critical point is discussed.

title: The integration of large biological and clinical datasets towards the understanding of human disease

Publisher: name: University of Glasgow

description: As the cost of high-throughput techniques reduces, and new more powerful equipment is designed, more highly-dimensional biological data will be available – and a lot of data is already in the public domain. The aim of this thesis is to investigate three case studies with interesting opportunities for the integration of large molecular datasets, corresponding clinical data, and publicly available data. Genome-wide DNA methylation was studied with respect to hypertension. Genomic location data was used both to group individual methylation sites into meaningful functional groups such as promoter regions, and to report the results in a genomic context. Genome-wide SNP data was used to help rule out potential false positives where SNPs interfere with detection of DNA methylation. Left ventricular hypertrophy is an intermediate cardiovascular phenotype associated with the development of heart failure. This phenotype was studied as a continuous variable – left ventricular mass index (LVMI) – using multiple sample types, in the context of a large cohort, using datasets with different classes of biomolecules and varying genomic coverage. Two alternative analysis approaches were compared, and a linear model was generated showing that a signature of molecular and clinical markers in combination best describes LVMI. A multi-omics respiratory dataset was investigated, which includes high-throughput data for mRNA, miRNA, proteins, and metabolites and has measurements in two relevant sample types. Test statistics were performed on all datasets, identifying molecules dysregulated with asthma, COPD, and smoking. An asthma molecular interaction network was created with the significant molecules, and the links between them were formed using a variety of public data. Comparisons were made between asthma and COPD, and between asthma in smokers and non-smokers. Correlations with cell type counts may indicate cell type of origin in samples with multiple cell types like induced sputum.
The mobility of dual vortices in honeycomb, square, triangular, Kagome and dice lattices

description: It was known that by a duality transformation, interaction bosons at filling factor $ f=p/q $ hopping on a lattice can be mapped to interacting vortices hopping on the dual lattice subject to a fluctuating{\em dual} " magnetic field" whose average strength through a dual plaquette is equal to the boson density $ f=p/q $.So the kinetic term of the vortices is the same as the Hofstadter problem of electrons moving in a lattice in the presence of $ f=p/q $ flux per plaquette. Motivated by this mapping, we study the Hofstadter bands of vortices hopping in the presence of magnetic flux $ f=p/q $ per plaquette on 5 most common bi-partisian and frustrated lattices such as square, honeycomb, triangular, dice and Kagome lattices. We also determine the number of minima and their locations in the lowest band. We numerically calculate the bandwidths of the lowest Hofstadter bands in these lattices and find that except the Kagome lattice at odd $ q $, they all satisfy the exponential decay law $ W = A e^{-cq} $ even at the smallest $ q $. We determine $ (A, c) $ for the 5 different lattices. When $ q=2 $, we find that the lowest Hofstadter band is completely flat for both Kagome and dice lattices. This indicates that the boson ground state at half filling with nearest neighbor hopping on Kagome and dice lattice is always a superfluid state,in contrast to the triangular lattice where the boson ground state was shown previously to undergo a transition from superfluid to supersolid state.

description: Recent work has proven the existence of extreme inbreeding in a European ancestry sample taken from the contemporary UK population \cite{nature_01}. This result brings our attention again to a math problem related to inbreeding family trees and diversity. Groups with a finite number of individuals could give a variety of genetic relationships. { In previous works \cite{PhysRevE.92.052132, PhysRevE.90.022125, JARNE20191}, we have addressed the issue of building inbreeding trees for biparental reproduction using Markovian models. Here, we extend these studies by presenting an algorithm to generate and represent inbreeding trees with no overlapping generations. We explicitly assume a two-gender reproductory scheme, and we pay particular attention to the links between nodes. We show that even for a simple case with a relatively small number of nodes in the tree, there are a large number of possible ways to rearrange the links between generations. We present an open-source python code to generate the tree graph, the adjacency matrix, and the histogram of the links for each different tree representation. We show how this mapping reflects the difference between tree realizations, and how valuable information may be extracted upon inspection of these matrices. The algorithm includes a feature to average several tree realizations, obtain the connectivity distribution, and calculate the average and mean value. We used this feature to compare trees with a different number of generations and nodes. The code presented here, available in Git-Hub, may be easily modified to be applied to other areas of interest involving connections between individuals, extend the study to add more characteristics of the different nodes, etc.

description: Proposals for realizing Majorana fermions in condensed matter systems typically rely on magnetic fields, which degrade the proximitizing superconductor and plague the Majoranas' detection. We propose an alternative scheme to realize Majoranas based only on phase-biased superconductors. The phases (at least three of them) can be biased by a tiny magnetic field threading macroscopic superconducting loops, focusing and enhancing the effect of the magnetic field onto the junction, or by supercurrents. We show how a combination of the superconducting phase winding and the spin-orbit phase induced in closed loops (Aharonov-Casher effect) facilitates a topological superconducting state with Majorana end states. We demontrate this scheme by an analytically tractable model as well as simulations of realistic setups comprising only conventional materials.

description: We used a controlled, uniform 5th-price auction to elicit values for sweet potatoes—both when location is known and unknown, and before and after tasting and providing health information. Significant differences were found between pre- and post-consumption valuations and also found that there were significant effects for location of origin and health information. Interestingly, we also find that location of origin not only affects the level of bids, but also the marginal differences in bids between different potatoes. Overall, however, these results suggest little consistency in bid values across information sets, suggesting that attempting to elicit values of attributes in isolation may lead to erroneous results.

description: Observations of the solar magnetic cycle showed that the amplitude of the cycle did not grow all the time in the past. Thus, there must be a mechanism to halt the growth of the magnetic field in the Sun. We demonstrate a recently proposed mechanism for this under the Babcock--Leighton dynamo framework, which is believed to be the most promising paradigm for the generation of the solar magnetic field at present. This mechanism is based on the observational fact that the stronger solar cycles produce bipolar magnetic regions (BMRs) at higher latitudes and thus have higher mean latitudes than the weaker ones. We capture this effect in our three-dimensional Babcock--Leighton solar dynamo model and show that when the toroidal magnetic field tries to grow, it produces BMRs at higher latitudes. The BMRs at higher latitudes generate a less poloidal field, which consequently limits the overall growth of the magnetic field in our model. Thus, our study suggests that the latitudinal variation of BMRs is a potential mechanism for limiting the magnetic field growth in the Sun.

description: Biological systems are known to be highly transparent to 700-1100nm near-infrared (NIR) light. It is shown here that the strong optical absorbance of single-walled carbon nanotubes (SWNTs) in this special spectral window, an intrinsic property of SWNTs, can be utilized for optical stimulation of nanotubes inside living cells to afford multifunctional nanotube biological transporters. For oligonucleotides transported inside living cells by nanotubes, the oligos can translocate into cell nucleus upon endosomal rupture triggered by NIR laser pulses. Continuous NIR radiation can cause cell death due to excessive local heating of SWNT in vitro. Selective cancer cell destruction can be achieved via functionalization of SWNT with a folate moiety, selective internalization of SWNTs inside cells labeled with folate receptor tumor-markers and NIR triggered cell death, without harming receptor-free normal cells. Thus, the transporting capabilities of carbon nanotubes combined with suitable functionalization chemistry and their intrinsic optical properties can lead to new classes of novel nanomaterials for drug delivery and cancer therapy.

description: Entropy plays a crucial role in characterization of information and entanglement, but it is not a scalar quantity and for many systems it is different for different relativistic observers. Loop quantum gravity predicts the Bekenstein-Hawking term for black hole entropy and logarithmic correction to it. The latter originates in the entanglement between the pieces of spin networks that describe black hole horizon. Entanglement between gravity and matter may restore the unitarity in the black hole evaporation process. If the collapsing matter is assumed to be initially in a pure state, then entropy of the Hawking radiation is exactly the created entanglement between matter and gravity.

description: Using supermarket survey data that include a store’s adoption of a new fresh irradiated ground beef product, this paper investigates whether the adoption decision-making process differs depending on whether adoption would make the store a leader or a follower. We model the adoption decision in two ways that take the leader-follower decision into account. Our results show only limited differences in store attributes across groups classified as leaders, followers, or non-adopters. More significantly, however, the results show that store attributes such as proximity to competitors and store size, among others, play separate roles in the decision to lead or follow.

description: We present Low Distortion Local Eigenmaps (LDLE), a manifold learning technique which constructs a set of low distortion local views of a dataset in lower dimension and registers them to obtain a global embedding. The local views are constructed using the global eigenvectors of the graph Laplacian and are registered using Procrustes analysis. The choice of these eigenvectors may vary across the regions. In contrast to existing techniques, LDLE can embed closed and non-orientable manifolds into their intrinsic dimension by tearing them apart. It also provides gluing instruction on the boundary of the torn embedding to help identify the topology of the original manifold. Our experimental results will show that LDLE largely preserved distances up to a constant scale while other techniques produced higher distortion. We also demonstrate that LDLE produces high quality embeddings even when the data is noisy or sparse.

The late time light curves can provide insight into the behavior of the decay products and their effect of the shape of the curves. We present the optical light curves of six "normal" Type Ia supernovae, obtained at late times with template image subtraction, and the fits of these light curves to supernova energy deposition models.

The predicted tetraquark mass $M_Z=3.99\pm0.09\,\rm{GeV}$ is in excellent agreement with the experimental value $3985.2^{+2.1}_{-2.0}\pm1.7\,\rm{MeV}$ from the BESIII collaboration, which supports identifying the $Z_{cs}(3985)$ as the cousin of the $Z_c(3900)$ with the quantum numbers $J^{PC}=1^{+-}$. We take into account the light flavor $SU(3)$ mass-breaking effect to estimate the mass spectrum of the diquark-antidiquark type hidden-charm tetraquark states having the strangeness according to the previous works.

In a simple model, we calculate the specific heat, linear and nonlinear magnetic susceptibilities and the change of transition temperature in a magnetic field with such an order parameter, and obtain quantitative agreement with experiments in terms of two parameters extracted from the data. The peculiar temperature dependence of the NMR linewidth and the nature of the loss of excitations in the ordered phase seen by neutron scattering are also explained and experiments are suggested to directly confirm the proposed order parameter.

description: This study utilized intra-firm, socio-cultural, geographical-proximity, and political-stability variables to explain bimodal foreign direct investment (FDI) patterns by agri-food and beverage multinational companies into and within the European Union. A logit framework incorporated a unique-count database of firm-level investment patterns from 1987–1998. The results showed the 1992 structural changes under the Maastricht Treaty increased the probability of wholly owned FDI modes such as greenfields and buyouts. The model also found that past modal strategies of firms, language barriers, and exchange-rate volatility all correctly explained modal investment patterns. The results provide important contributions toward understanding modal investment strategies including the role of macroeconomic changes within a custom union.

We calculate the eight independent polarization parameters from the spin density matrix elements of the $Z$, which can probe underlying new physics contributions to $ZH$ production. By using the approach that connects these polarization observables to the coefficients in the angular distribution of the decay products of the $Z$, we estimate the limits on the anomalous $ZZH$ coupling that can be obtained at the 14 TeV LHC.

Although B-twisted Landau-Ginzburg models have been discussed extensively in the literature, virtually no work has been done on A-twisted theories. In particular, we study examples of Landau-Ginzburg models over topologically nontrivial spaces - not just vector spaces - away from large-radius limits, so that one expects nontrivial curve corrections. By studying examples of Landau-Ginzburg models in the same universality class as nonlinear sigma models on nontrivial Calabi-Yaus, we obtain nontrivial tests of our methods as well as a physical realization of some simple examples of virtual fundamental class computations.

description: In his lifelong effort to overcome the limits of Panofsky’s iconological method, Max Imdahl tried to sketch out an «iconic understanding» which is pre-reflexive, performed below the level of conceptual and verbal explication. Under the auspices of Konrad Fiedler’s theoretical position, Imdahl opposed the Panofskian «recognizing view» with a more formalistic «seeing view», in order to gain access to a third form of vision which he called «knowing view». After outlining Imdahl’s critic of the reduced and unilateral significance of «form» and «formal composition» in Panofsky’s approach, I will clarify how far Imdahl has gone in the analysis of what should be properly defined as an authentic logic of images. Then, focusing on a paradigmatic case study, I will show the importance of the syntax of an image (i.e. the positioning of its elements on the left or on the right, underneath or above, in the back or in the front) for its semantic meaning.

In this contribution, complementing recent investigations of Ishihara and Ogawa, we present a detailed investigation of charge screening using a perturbative approach with the charge strength as an expansion parameter. It is shown how perfect global and remarkably good local screening can be derived from Gauss' theorem, and the asymptotic form of the fields far from the sources. The perturbative results are shown to compare favourably to the numerical ones.

description: We consider the relationship between the total HI mass in late-type galaxies and the kinematic properties of their disks. The mass $M_HI$ for galaxies with a wide variety of properties, from dwarf dIrr galaxies with active star formation to giant low-brightness galaxies, is shown to correlate with the product $V_c R_0$ ($V_c$ is the rotational velocity, and $R_0$ is the radial photometric disks scale length), which characterizes the specific angular momentum of the disk. This relationship, along with the anticorrelation between the relative mass of HI in a galaxy and $V_c$, can be explained in terms of the previously made assumption that the gas density in the disks of most galaxies is maintained at a level close to the threshold (marginal) stability of a gaseous layer to local gravitational perturbations. In this case, the regulation mechanism of the star formation rate associated with the growth of local gravitational instability in the gaseous layer must play a crucial role in the evolution of the gas content in the galactic disk.

description: In the standard Lambda-CDM paradigm, dwarf galaxies are expected to be dark-matter-rich, as baryonic feedback is thought to quickly drive gas out of their shallow potential wells and quench star formation at early epochs. Recent observations of local dwarfs with extremely low dark matter content appear to contradict this picture, potentially bringing the validity of the standard model into question. We use NewHorizon, a high-resolution cosmological simulation, to demonstrate that sustained stripping of dark matter, in tidal interactions between a massive galaxy and a dwarf satellite, naturally produces dwarfs that are dark-matter-deficient, even though their initial dark matter fractions are normal. The process of dark matter stripping is responsible for the large scatter in the halo-to-stellar mass relation in the dwarf regime. The degree of stripping is driven by the closeness of the orbit of the dwarf around its massive companion and, in extreme cases, produces dwarfs with halo-to-stellar mass ratios as low as unity, consistent with the findings of recent observational studies. ~30 per cent of dwarfs show some deviation from normal dark matter fractions due to dark matter stripping, with 10 per cent showing high levels of dark matter deficiency (Mhalo/M*<10). Given their close orbits, a significant fraction of dark-matter-deficient dwarfs merge with their massive companions (e.g. ~70 per cent merge over timescales of ~3.5 Gyrs), with the dark-matter-deficient population being constantly replenished by new interactions between dwarfs and massive companions. The creation of these galaxies is, therefore, a natural by-product of galaxy evolution and their existence is not in tension with the standard paradigm.

description: Purpose: Hearing loss is the third most prevalent chronic health condition among adults in the United States. Rural adults face disproportionately high rates of hearing loss and numerous systemic barriers to hearing health care (HHC). This study aims to explore experiences of hearing loss, identify factors that impact access, and assess the potential acceptability of a patient navigation program. Perspectives of patients experiencing hearing loss and rural health care providers are vital for designing an intervention that addresses barriers to HHC experienced in rural settings.Method: As the first phase of a larger project guided by the PRECEDE-PROCEED planning model, a qualitative needs assessment was conducted using semistructured interviews with 21 adult primary care patients with hearing loss and 11 health care personnel from primary care clinics in rural Kentucky. Thematic analysis identified predisposing, enabling, and need factors perceived as influencing whether HHC is accessed by rural adults with hearing loss.Results: Analyses revealed that patients accessing HHC was perceived to be affected by predisposing (concerns about noise exposure and attitudes about HHC), enabling (connection to HHC and resources, lack of local HHC services, communication challenges, transportation challenges, and cost of care), and need factors (experience with hearing loss). Participants agreed that a patient navigator (PN) could increase access to HHC by providing social support and by connecting patients to education and resources.Conclusions: Results from this analysis will inform the development of a patient navigation intervention for HHC for rural adults. PNs will receive specialized training to help patients meet stated needs and overcome commonly reported barriers.Supplemental Material S1.

Axisymmetric stability criteria for a composite system of stellar and magnetized gaseous singular isothermal discs

description: Using the fluid-magnetofluid formalism, we obtain axisymmetric stability criteria for a composite disc system consisting of stellar and gaseous magnetized singular isothermal discs (MSIDs). Lou & Zou recently constructed exact global stationary configurations for both axisymmetric and nonaxisymmetric coplanar MHD perturbations in such a composite MSID system and proposed the MHD $D_s-$criteria for axisymmetric stability by the hydrodynamic analogy. In a different perspective, we derive and analyze here the time-dependent WKBJ dispersion relation in the low-frequency and tight-winding regime to examine axisymmetric stability properties. By introducing a rotational Mach number $D_s$ for the ratio of the stellar rotation speed $V_s$ to the stellar velocity dispersion $a_s$, one readily determines the stable range of $D_s^2$ numerically to establish the $D_s-$criteria for axisymmetric MSID stability. Those MSID systems rotating either too fast (ring ragmentation) or too slow (Jeans collapse) are unstable. Our WKBJ results of (M)SID instability provide physically compelling explanations for the stationary analysis of Lou & Zou. We further introduce an effective MHD $Q$ parameter for a composite MSID system and compare with the earlier work of Elmegreen, Jog and Shen & Lou. As expected, an axisymmetric dark matter halo enhances the stability against axisymmetric disturbances in a composite partial MSID system.

description: Historically, China's political attempts to provide access to rural credit has met with mixed results and an institutional structure that often strays from intended policy goals. There has been a close correspondence between financial depression and many policy-driven financial institutions that dominated the rural financial system in China. More recently, ongoing reforms are dedicated towards a gradual liberalization within the system. In this study, we explore the context of agricultural transition and political process as defined by the various interlinkages across the Chinese rural financial system. We find that there has been negligible progress in the evolution of the rural financial market in China. The policy-led financial institutions ended up as merely a disbursement window and a costly drain on state budget. Institutional changes were locked in by patching up the existing institutions.

description: Das Ziel dieser Arbeit ist, die elektronischen Eigenschaften von CZTS zu verstehen. Ein leistungsfahigesWerkzeug zu diesem Zweck ist die Rontgen-Nahkanten Absorptions-Spektroskopie (XANES). Die Interpretation von XANES-Spektren komplexer Materialien ist nicht trivial und erfordert daher theoretische Modellierung. Alle Rechnungen in dieser Arbeit wurden mittels der im exciting Code implementierten Linearized-Augmented-Plane- Wave-Methode, welche alle Elektronen gleichberechtigt behandelt, durchgefuhrt. Die genaue Beschreibung der Anregungen von Kernzustanden wird durch ein zweistufiges Verfahren erreicht. Zunachst wird die elektronische Struktur berechnet, indem die Kohn-Sham-Gleichungen (KS) der Dichtefunktionaltheorie (DFT) gelost werden. Die Absorptionsspektren unter Berucksichtigung der Elektron-Loch-Wechselwirkung (e-h) werden durch die Losung der Bethe-Salpeter Gleichung (BSE) der Vielteilchen-Storungstheorie (MBPT) unter Einsatz der KS-Zustonde als Ausgangspunkt beschrieben.
description: The aim of this work is to understand the electronic properties of CZTS. X-ray absorption near edge structure (XANES) is a powerful tool for this purpose. Interpreting XANES of complex materials is nontrivial and thus requires theoretical modeling. Here, all the calculations are performed using an all-electron full-potential augmented plane-wave method as implemented in the exciting code. The accurate description of the core level excitations is performed by a two-step procedure. First, the electronic structure is calculated by solving the Kohn-Sham (KS) equation of density functional theory (DFT). The absorption spectra including electron-hole (e-h) is described by the solution of the Bethe-Salpeter equation (BSE) of many-body perturbation theory (MBPT) using the KS states as starting point.

description: In this paper, we analyze the properties of invertible neural networks, which provide a way of solving inverse problems. Our main focus lies on investigating and controlling the Lipschitz constants of the corresponding inverse networks. Without such an control, numerical simulations are prone to errors and not much is gained against traditional approaches. Fortunately, our analysis indicates that changing the latent distribution from a standard normal one to a Gaussian mixture model resolves the issue of exploding Lipschitz constants. Indeed, numerical simulations confirm that this modification leads to significantly improved sampling quality in multimodal applications.
