description: Structural variants (SVs) contribute to many disorders, yet, functionally annotating them remains a major challenge. Here, we integrate SVs with RNA-sequencing from human post-mortem brains to quantify their dosage and regulatory effects. We show that genic and regulatory SVs exist at significantly lower frequencies than intergenic SVs. Functional impact of copy number variants (CNVs) stems from both the proportion of genic and regulatory content altered and loss-of-function intolerance of the gene. We train a linear model to predict expression effects of rare CNVs and use it to annotate regulatory disruption of CNVs from 14,891 independent genome-sequenced individuals. Pathogenic deletions implicated in neurodevelopmental disorders show significantly more extreme regulatory disruption scores and if rank ordered would be prioritized higher than using frequency or length alone. This work shows the deleteriousness of regulatory SVs, particularly those altering CTCF sites and provides a simple approach for functionally annotating the regulatory consequences of CNVs.

description: This work reports an experimental and numerical analysis on the sooting characteristics of butanol isomers. Light extinction and gas chromatography were used to measure soot and gas-phase species, respectively. Kinetic analysis of the tested flames was performed with detailed gas-phase mechanism and a sectional soot model. The present work aims to provide an understanding on the effects of butanol isomeric structures on sooting tendencies. For a comprehensive analysis, flames of both neat butanol fuels and butanol/hydrocarbon mixtures were studied. The results showed that the relative ranking of sooting tendencies among the butanol isomers were similar in neat butanol flames and in butanol-doped ethylene flames. In addition, we show that a small amount of butanol addition in ethylene flame enhanced soot formation. It was found that different isomeric structures mainly affected the formation of C3H3, which led to the different concentrations of important aromatic soot precursors. In the butanol-doped ethylene flames, the blending of the four butanol isomers increased the number of C3H3 formation pathways, which in turn significantly increased the production of benzene. Structural effects explaining for the differences in the sooting tendencies of the four butanol isomers in neat butanol flames and ethylene/butanol flames were found to be the same.

description: AbstractObjective: This study aimed to investigate if retroverted (RV) uterus noted on nuchal translucency (NT) ultrasound is associated with second-trimester pregnancy loss and other adverse pregnancy outcomes.Study design: This was a retrospective cohort study of patients with RV uterus documented on NT ultrasound at a single academic medical center from October 2019 to March 2023. Subjects were identified using a query for "retroverted" uterine position within an obstetric ultrasound imaging program. For each RV case, two anteverted (AV) subjects were selected for comparison. Patients with multiple gestation, Mullerian anomalies, or fetal aneuploidy were excluded. Maternal demographics, obstetric, and neonatal outcomes were obtained by chart review. Fisher's exact test and Mann-Whitney test were used for categorical and continuous variables, respectively, with p-value <0.05 denoting significance. Multivariable logistic regression was used to adjust for possible confounding variables.Results: Analysis included 249 patients-83 RV and 166 AV. RV patients were more likely to identify as Caucasian (71.1 vs. 49.4%, p = 0.001), have private insurance (80.7 vs. 59.4%, p = 0.001), lower body mass index (25.4 ± 5.1 vs 29.1 ± 7.2, p < 0.001), and conceive by in vitro fertilization (IVF, 11 vs. 3%, p = 0.018). Most RV subjects (98%) had a resolution of retroversion by the second trimester. There was no difference in second-trimester pregnancy loss (0 vs. 1.2%, p = 0.55). After adjusting for race and IVF, RV subjects were four times more likely to have first-trimester vaginal bleeding (16.9 vs. 4.2%, odds ratio = 4.1, p = 0.0056). No other differences in adverse outcomes were observed.Conclusion: Persistent RV uterus in the first trimester is associated with increased risk of first-trimester vaginal bleeding. However, rates of pregnancy loss were similar between groups, providing valuable information for patient counseling. Significantly more RV subjects conceived by IVF, highlighting the need for further study in this population.Key points: ·Pregnancy outcomes of patients with retroverted uterus have not been widely studied.. · Significantly more patients with a retroverted uterus conceived by in vitro fertilization.. · Patients with retroverted uterus were four times more likely to have first-trimester bleeding.. · Despite increased rates of vaginal bleeding, there was no increased rate of pregnancy loss..

description: Hematopoietic stem and progenitor cells (HSPCs) are crucial for lifelong blood cell production. We analyzed the cell cycle and cell production rate in HSPCs in murine hematopoiesis. The labeling of DNA-synthesizing cells by two thymidine analogues, optimized for in-vivo use, enabled determination of the cell cycle flow rate into G2-phase, the duration of S-phase and the average cell cycle time in Sca-1+ and Sca-1− HSPCs. Determination of cells with 2n DNA content labeled in preceding S-phase was then used to establish the cell flow rates in G1-phase. Our measurements revealed a significant difference in how Sca-1+ and Sca-1− myeloid progenitors self-renew and differentiate. Division of the Sca-1+ progenitors led to loss of the Sca-1 marker in about half of newly produced cells, corresponding to asymmetric cell division. Sca-1− cells arising from cell division entered a new round of the cell cycle, corresponding to symmetric self-renewing cell division. The novel data also enabled the estimation of the cell production rates in Sca-1+ and in three subtypes of Sca-1− HSPCs and revealed Sca-1 negative cells as the major amplification stage in the blood cell development.
title: Processing of Space Surveillance Observations

Publisher: name: Universität Bern
Year: 2021
Subjects: subject: 520 Astronomy

description: This thesis covers the processing of different types of space surveillance measurements. The emphasis is on the initial build-up of a catalogue. Most experiments focus on the identification of objects from pairs of observations by testing whether these two observations could originate from the same object. The advantage of this approach is that an orbit from two passes is usually more precise than that from a single pass and thus the chance of associating subsequent measurements with this newly derived orbit is higher.

The main contribution is the introduction of a method for perturbed initial orbit determination and observation correlation from two radar tracklets. The perturbed initial orbit determination provides the solutions for all possible numbers of revolutions from two positions under consideration of the secular J2-perturbations, which causes for example the rotation of the orbital plane. The perturbations are considered analytically in an iterative process. From the different numbers of revolutions, the most probable solution can either be selected via the minimum Mahalanobis distance, using the range-rate as a remaining observable, or after an additional post-processing. The robustness and applicability of the method is shown using real radar measurements, which includes a large percentage of successful initial orbit determinations for tracklets which are more than 20 days apart. This method is also extended to the combination of optical and radar measurements for objects in Highly Elliptical Orbits.

Concerning the simulation of a cold-start of a catalogue, two different processing strategies are introduced. One is adding a least squares orbit determination using a pair of possibly correlated tracklets, while the other approach collects data over a longer time span and generates a graph network from which clusters of tracklets are derived as new candidate objects.

Further analysis focuses on aspects of operational processing of space surveillance measurements. This includes the automated decision making process for the monitoring of the quality of existing catalogue objects and the design of an autonomous processing pipeline for optical measurements at the Zimmerwald observatory. A potential space mission to observe the Geostationary Orbit is also analysed with regard to its performance during the catalogue build-up.

description: Differences in looking at the eyes of others are one of the earliest behavioral markers for social difficulties in neurodevelopmental disabilities, including autism. However, it is unknown how early visuo-social experiences relate to the maturation of infant brain networks that process visual social stimuli. We investigated functional connectivity (FC) within the ventral visual object pathway as a contributing neural system. Densely sampled, longitudinal eye-tracking and resting state fMRI (rs-fMRI) data were collected from infant rhesus macaques, an important model of human social development, from birth through 6 months of age. Mean trajectories were fit for both datasets and individual trajectories from subjects with both eye-tracking and rs-fMRI data were used to test for brain-behavior relationships. Exploratory findings showed infants with greater increases in FC between left V1 to V3 visual areas have an earlier increase in eye-looking before 2 months. This relationship was moderated by social status such that infants with low social status had a stronger association between left V1 to V3 connectivity and eye-looking than high status infants. Results indicated that maturation of the visual object pathway may provide an important neural substrate supporting adaptive transitions in social visual attention during infancy.

description: Amid rising mental health concerns in New Zealand schools, the imperative for teachers to grasp psychological capital's principles is underscored in this concise overview. Seven key reasons illuminate the significance of this understanding. Teachers, as central figures in student development, play a pivotal role in supporting well-being by instilling hope, efficacy, resilience, and optimism. Importantly, awareness of psychological capital enables early identification and intervention, equipping students with essential coping skills.Fostering a positive classroom culture is another vital dimension. Teachers, armed with psychological capital knowledge, contribute significantly to reducing mental health stigma and creating environments conducive to seeking support. The impact isn't unidirectional; teacher well-being is positively influenced, enhancing overall job satisfaction.Aligning with New Zealand's focus on holistic well-being, integrating psychological capital into education resonates with the vision of nurturing resilient individuals. Improved classroom dynamics result from teachers actively incorporating these principles, enhancing both learning experiences and relationships.The discussion is substantiated by a succinct review of pertinent literature, referencing foundational works by Luthans and Youssef on psychological capital. Additionally, local context is acknowledged through references to New Zealand-specific research on mental health in schools. Citations from educational psychology journals fortify the argument, offering a concise yet comprehensive insight into the critical role of psychological capital in addressing mental health challenges facing our educational system n New Zealand schools.

description: The environmental stability of the layered semiconductor black phosphorus (bP) remains a challenge. Passivation of the bP surface with phosphorus oxide, POx, grown by a reactive ion etch with oxygen plasma is known to improve photoluminescence efficiency of exfoliated bP flakes. We apply phosphorus oxide passivation in the fabrication of bP field effect transistors using a gate stack consisting of a POx layer grown by reactive ion etching followed by atomic layer deposition of Al2O3. We observe room temperature top-gate mobilities of 115 cm2/Vs in ambient conditions, which we attribute to the low defect density of the bP/POx interface.

description: Macroautophagy/autophagy is a conserved degradation process in eukaryotic cells involving the sequestration of proteins and organelles within double-membrane vesicles termed autophagosomes. In filamentous fungi, its main purposes are the regulation of starvation adaptation and developmental processes. In contrast to nonselective bulk autophagy, selective autophagy is characterized by cargo receptors, which bind specific cargos such as superfluous organelles, damaged or harmful proteins, or microbes, and target them for autophagic degradation. Herein, using the core autophagy protein ATG8 as bait, GFP-Trap analysis followed by liquid chromatography mass spectrometry (LC/MS) identified a putative homolog of the human autophagy cargo receptor NBR1 (NBR1, autophagy cargo receptor) in the filamentous ascomycete Sordaria macrospora (Sm). Fluorescence microscopy revealed that SmNBR1 colocalizes with SmATG8 at autophagosome-like structures and in the lumen of vacuoles. Delivery of SmNBR1 to the vacuoles requires SmATG8. Both proteins interact in an LC3 interacting region (LIR)-dependent manner. Deletion of Smnbr1 leads to impaired vegetative growth under starvation conditions and reduced sexual spore production under non-starvation conditions. The human NBR1 homolog partially rescues the phenotypic defects of the fungal Smnbr1 deletion mutant. The Smnbr1 mutant can neither use fatty acids as a sole carbon source nor form fruiting bodies under oxidative stress conditions. Fluorescence microscopy revealed that degradation of a peroxisomal reporter protein is impaired in the Smnbr1 deletion mutant. Thus, SmNBR1 is a cargo receptor for pexophagy in filamentous ascomycetes.

description: There has recently been interest in the role of inverse bremsstrahlung, the emission of photons by fast suprathermal ions in collisions with ambient electrons possessing relatively low velocities, in tenuous plasmas in various astrophysical contexts. This follows a long hiatus in the application of suprathermal ion bremsstrahlung to astrophysical models since the early 1970s. The potential importance of inverse bremsstrahlung relative to normal bremsstrahlung, i.e. where ions are at rest, hinges upon the underlying velocity distributions of the interacting species. In this paper, we identify the conditions under which the inverse bremsstrahlung emissivity is significant relative to that for normal bremsstrahlung in shocked astrophysical plasmas. We determine that, since both observational and theoretical evidence favors electron temperatures almost comparable to, and certainly not very deficient relative to proton temperatures in shocked plasmas, these environments generally render inverse bremsstrahlung at best a minor contributor to the overall emission. Hence inverse bremsstrahlung can be safely neglected in most models invoking shock acceleration in discrete sources such as supernova remnants. However, on scales > 100pc distant from these sources, Coulomb collisional losses can deplete the cosmic ray electrons, rendering inverse bremsstrahlung, and perhaps bremsstrahlung from knock-on electrons, possibly detectable.

description: Alien fishes are regarded as one of the major causes of the decline of aquatic fauna and biodiversity. Up to now, more than 500 fish species have been introduced into China from other countries. However, nationwide documentation of the established alien fishes is still lacking and their ecological risk is unclear. We compiled a comprehensive inventory of the colonized alien fish species based on various sources, and then provided a summary of their potential ecological risk. The results indicated that 68 alien fish species (13.44%) have successfully established in the natural waters. These species belong to 12 orders and 29 families. Among them, 56 species (82.35%) were introduced for aquaculture purposes, 11 species (16.18%) were introduced for aquarium and one species (1.47%) was introduced for bio-control. Over 85% of the established fishes were introduced after the 1970s. Geographically, these species are native to 12 regions around the world. Eighteen species and two hybrid species are native to North America which is the most dominant donor. Among these species, 61 can live in freshwater, 41 species can live in brackish and 19 species can live in marine water. Although large number of species, high taxonomic diversity, intensive human activity, diverse geographical origins and high adaptability of non-native species may lead to the increase of invasion risk, previous research about invasive risk just focus on the general impact of aquaculture activities, invasiveness screening using semi-quantitative models and distribution prediction using species distribution models. Further studies will need to be conducted on comprehensive risk assessment, ecological interaction between non-native fish and new environment, on fish species, ecosystem, the impact of human activity and global change on non-native fish colonization.

description: Arrays of H-shape microfluidic channels connecting two different fluidic reservoirs have been built with silicon/SU8 microfabrication technologies utilized in production of thermal inkjet printheads. The fluids are delivered to the channels via slots etched through the silicon wafer. Every H-shape channel comprises four thermal inkjet resistors, one in each of the four legs. The resistors vaporize water and generate drive bubbles that pump the fluids from the bulk reservoirs into and out of the channels. By varying relative frequencies of the four pumps, input fluids can be routed to any part of the network in any proportion. Several fluidic operations including dilution, mixing, dynamic valving, and routing have been demonstrated. Thus, a fully integrated microfluidic switchboard that does not require external sources of mechanical power has been achieved. A matrix formalism to describe flow in complex switchboards has been developed and tested.

description: The star formation rate history of the Milky Way is derived using the chromospheric age distribution for 552 stars in the solar neighborhood. The stars sample birthsites distributed over a very large range of distances because of orbital diffusion, and so give an estimate of the global star formation rate history. The derivation incorporates the metallicity dependence of chromospheric emission at a given age, and corrections to account for incompleteness, scale height-age correlations, and stellar evolutionary effects. The results show that the Milky Way has undergone fluctuations in the global star formation rate with amplitudes greater than a factor of 2-3 on timescales less than 0.2-1 Gyr. The actual history is likely to be more bursty than found here because of the smearing effect of age uncertainties. There is some evidence for a slow secular increase in the star formation rate, perhaps a record of the accumulation history of our galaxy. A smooth nearly-constant star formation rate history is strongly ruled out, confirming the result first discovered by Barry (1988) using a smaller sample and a different age calibration. This result suggests that galaxies can fluctuate coherently on large scales.

description: We aim to use multi-band imaging from the Phase-3 Verification Data of the J-PLUS survey to derive accurate photometric redshifts (photo-z) and look for potential new members in the surroundings of the nearby galaxy clusters A2589 (z=0.0414) & A2593 (z=0.0440), using redshift probability distribution functions. The ultimate goal is to demonstrate the usefulness of a 12-band filter system in the study of large-scale structure in the local universe. We present an optimized pipeline for the estimation of photo-z in clusters of galaxies. We tested our photo-z with a sample of 296 spectroscopically confirmed cluster members with a magnitude of = 16.6 and redshift =0.041. The combination of seven narrow and five broadband filters with a typical photometric-depth of r<21.5 provides dz/(1+z)=0.01 photo-z estimates. A precision of dz/(1+z)=0.005 is obtained for the 177 galaxies brighter than magnitude r<17. To foresee the precision beyond the spectroscopic sample, we designed a set of simulations in which real cluster galaxies are modeled and reinjected inside the images at different signal-to-noise. A precision of dz/(1+z)=0.02 and dz/(1+z)=0.03 is expected at = 18-22, respectively. Complementarily, we used SDSS/DR12 data to derive photo-z estimates for the same galaxy sample, demonstrating that the wavelength-resolution of the J-PLUS can double the precision achieved by SDSS for galaxies with a high S/N. We find as much as 170 new candidates across the entire field. The spatial distribution of these galaxies may suggest an overlap between the systems with no evidence of a clear filamentary structure connecting the clusters. These preliminary results show the potential of J-PLUS data to revisit membership of groups and clusters from nearby galaxies, important for the determination of luminosity and mass functions and environmental studies at the intermediate and low-mass regime.

description: Mechanical resonators made with monolithic piezoelectric quartz crystals are promising for studying new physical phenomena. High mechanical quality factors ($Q$) exhibited by the mm-sized quartz resonators make them ideal for studying weak couplings or long timescales in the quantum regime. However, energy losses through mechanical supports pose a serious limiting factor for obtaining high quality factors. Here we investigate how the $Q$ of quartz resonators at deep cryogenic temperatures can be limited by several types of losses related to anchoring. We first introduce means to reduce the mechanical losses by more than an order of magnitude in a no-clamping scheme, obtaining $Q$-factors of $10^8$ of the lowest shear mode. We can exclude a wide coverage of aluminum metallization on the disk or bond wires as sources of dissipation. However, we find a dramatic reduction of the $Q$-factor accompanying an electrode configuration that involves strong focusing of the vibrations in the disk center. We propose a circuit model that accounts for the reduced mechanical $Q$-factor in terms of electrical losses. In particular, we show how the limiting factor for losses can be small ohmic dissipation in a grounding connection, which can be interpreted as electrical anchor losses of the mechanical device.

Further rise’ing to the challenge of type 2 diabetes in youth

description: Despite three decades of increasing prevalence of type 2 diabetes (T2D) in adolescents, the diabetes community continues to grapple with the pathophysiology of youth-onset T2D. Accumulating evidence indicates that when compared with T2D in adults, T2D in youth follows a more aggressive course. Adolescents are therefore entering adulthood with an advanced and perhaps misunderstood disease that puts them at risk for morbidity from micro- and macrovascular complications. Moreover, as the susceptibility of individuals with diabetes to poor outcomes during the coronavirus pandemic became increasingly apparent, the urgency to address the health crisis of T2D in youth has been amplified.
Bounding Effective Operators at the One-Loop Level: The Case of Four-Fermion Neutrino Interactions

description: The contributions of non-standard four-neutrino contact interactions to electroweak observables are considered at the one-loop level by using the effective quantum field theory. The analysis is done in terms of three unknown parameters: the strength of the non-standard neutrino interactions, $\tilde{F}$, an additional derivative coupling needed to renormalize the divergent contributions that appear when the four-neutrino interactions are used at the loop level and a non-standard non-derivative $Z$-${\barν} ν$ coupling. Then, the precise measurements of the invisible width of the $Z$-boson at LEP and the data on the neutrino deep-inelastic scattering yield the result $\tilde{F} = (-100 \pm 140) G_F$. Assuming that there are no unnatural cancellations between the contributions of the three effective couplings a much stronger bound is obtained: $\abs{\tilde{F}}\ltap~ 2 G_F$, which is a factor 200 better than the one obtained in previous analyses based on tree level calculations.

Faint blue objects on the Hubble Deep Field North & South as possible nearby old halo white dwarfs

description: Using data derived from the deepest and finest angular resolution images of the universe yet acquired by astronomers at optical wavelengths using the Hubble Space Telescope (HST) in two postage-stamp sections of the sky (Williams et al. 1996a,b), plus simple geometrical and scaling arguments, we demonstrate that the faint blue population of point-source objects detected on those two fields (Méndez et al. 1996) could actually be ancient halo white dwarfs at distances closer than about 2 kpc from the Sun. This finding has profound implications, as the mass density of the detected objects would account for about half of the missing dark matter in the Milky-Way (Bahcall and Soneira 1980), thus solving one of the most controversial issues of modern astrophysics (Trimble 1987, Ashman 1992). The existence of these faint blue objects points to a very large mass locked into ancient halo white dwarfs. Our estimate indicates that they could account for as much as half of the dark matter in our Galaxy, confirming the suggestions of the MACHO microlensing experiment (Alcock et al. 1997). Because of the importance of this discovery, deep follow-up observations with HST within the next two years would be needed to determine more accurately the kinematics (tangential motions) for these faint blue old white dwarfs.

description: We consider the flavour problem in a supersymmetric Grand Unified theory with gauged SU(6) group, where the Higgs doublets are understood as pseudo-Goldstone bosons of a larger $\SU(6)\otimes\SU(6)$ global symmetry of the Higgs superpotential. A key element of this work is that we never appeal to any flavour symmetry. One main interesting feature emerges: only one of the light fermions, an up-type quark, to be identified with the top, can get a Yukawa coupling at renormalizable level. This fact, together with bottom-tau Yukawa unification, also implied in our scheme, gives rise to a characteristic correlation between the top and the Higgs mass. By including a flavour-blind discrete symmetry and requiring that all higher dimensional operators be mediated by the exchange of appropriate heavy multiplets, it is possible to give an approximate description of all masses and mixing angles in term of a hierarchy of grand unified scales. A special ``texture'' arises, implying a relation between the top mass and the third generation mixing angles. Several other possible consequences of this approach are pointed out, concerning the $μ/s$ mass ratio, the Cabibbo angle and the proton decay.

description: To determine that two given undirected graphs are isomorphic, we construct for them auxiliary graphs, using the breadth-first search. This makes capability to position vertices in each digraph with respect to each other. If the given graphs are isomorphic, in each of them we can find such positionally equivalent auxiliary digraphs that have the same mutual positioning of vertices. Obviously, if the given graphs are isomorphic, then such equivalent digraphs exist. Proceeding from the arrangement of vertices in one of the digraphs, we try to determine the corresponding vertices in another digraph. As a result we develop the algorithm for constructing a bijective mapping between vertices of the given graphs if they are isomorphic. The running time of the algorithm equal to $O(n^5)$, where $n$ is the number of graph vertices.

description: This work investigates a scalable building performance simulation (BPS) based on a modular setup deploying the recently developed functional mock-up interface standard. A procedure for the realization of such an approach is presented and a prototypical implementation is described. One of the key obstacles of the modular simulation is identified to be the collocation of simulation modules, which is addressed using a knowledge-based method enabled through ontology. The procedure allows to automatically derive a simulation topology based on the information about the interfacing variables for varying levels of detail. Also information from other sources such as building information models is incorporated. The feasibility of the proposed method is demonstrated by deploying it in test cases of a single-zone and a multi-zone BPS as well as a zonal airflow simulation.
Label-free imaging of cholesterol and lipid distributions in model membranes

description: Over recent decades, lipid membranes have become standard models for examining the biophysics and biochemistry of cell membranes. Interrogation of lipid domains within biomembranes is generally done with fluorescence microscopy via exogenous chemical probes. However, most fluorophores have limited partitioning tunability, with the majority segregating in the least biologically relevant domains (i.e., low-density liquid domains). Therefore, a molecular-level picture of the majority of non-labeled lipids forming the membrane is still elusive. Here, we present simple, label-free imaging of domain formation in lipid monolayers, with chemical selectivity in unraveling lipid and cholesterol composition in all domain types. Exploiting conventional vibrational contrast in spontaneous Raman imaging, combined with chemometrics analysis, allows for examination of ternary systems containing saturated lipids, unsaturated lipids, and cholesterol. We confirm features commonly observed by fluorescence microscopy, and provide an unprecedented analysis of cholesterol distribution at the single-membrane level.
Local Kernels that Approximate Bayesian Regularization and Proximal Operators

description: In this work, we broadly connect kernel-based filtering (e.g. approaches such as the bilateral filters and nonlocal means, but also many more) with general variational formulations of Bayesian regularized least squares, and the related concept of proximal operators. The latter set of variational/Bayesian/proximal formulations often result in optimization problems that do not have closed-form solutions, and therefore typically require global iterative solutions. Our main contribution here is to establish how one can approximate the solution of the resulting global optimization problems with use of locally adaptive filters with specific kernels. Our results are valid for small regularization strength but the approach is powerful enough to be useful for a wide range of applications because we expose how to derive a "kernelized" solution to these problems that approximates the global solution in one-shot, using only local operations. As another side benefit in the reverse direction, given a local data-adaptive filter constructed with a particular choice of kernel, we enable the interpretation of such filters in the variational/Bayesian/proximal framework.
Nambu mass hierarchies in strings

description: We show that a recent proposal by Nambu to generate a hierarchy among Yukawa couplings in the standard model may be easily implemented in superstring models. In such models, two of the main ingredients of the Nambu proposal find a natural explanation: minimising with respect to the Yukawas amounts to a minimisation with respect to the underlying moduli fields and a constraint on the Yukawas of the type of the Veltman condition may be attributed to the relaxation process to a phenomenologically viable string vacuum.

description: Recently, scale-scale correlations have been detected in the distributions of quasar's Ly$α$ absorption lines and the maps of cosmic temperature fluctuations. In this paper, we investigate the scale-scale correlations in galaxy distributions. Using samples of mass field given by N-body simulation, we first show that the scale-scale correlation of 2-D and 3-D mass distributions at present day is capable of breaking the degeneracy between the SCDM (standard cold dark matter model) and OCDM (open CDM model) or LCDM (flat CDM model), and even show the difference between the OCDM and LCDM. Using biased galaxy samples produced in an appropriate bias model, we show that the scale-scale correlation of galaxy distribution at zero redshift is still a powerful tool to break the degeneracy in the parameter space, including both cosmological and biasing parameters. We analyze the scale-scale correlations of the APM bright galaxy catalog, and compare it with the mock catalog in the SCDM, OCDM and LCDM models. We find that all the spectra of local and non-local scale-scale correlations predicted by the OCDM model are in excellent agreement with those of the APM-BGC sample, while the SCDM and LCDM mock catalog appear to have somewhat weaker scale-scale correlations than the observation.

Local Self-Energies for V and Pd Emergent from a Non-Local LDA+FLEX Implementation

description: In the spirit of recently developed LDA+U and LDA+DMFT methods we implement a combination of density functional theory in its local density approximation (LDA) with a $k$- and $ω-$dependent self-energy found from diagrammatic fluctuational exchange (FLEX) approximation. The active Hilbert space here is described by the correlated subset of electrons which allows to tremendously reduce the sizes of matrices needed to represent charge and spin susceptibilities. The method is perturbative in nature but accounts for both bubble and ladder diagrams and accumulates the physics of momentum resolved spin fluctuations missing in such popular approach as GW. As an application, we study correlation effects on band structures in V and Pd. The d-electron self-energies emergent from this calculation are found to be remarkably k-independent. However, when we compare our calculated electronic mass enhancements against LDA+DMFT, we find that for a long standing problem of spin fluctuations in Pd, LDA+FLEX delivers a better agreement with experiment, although this conclusion depends on a particular value of Hubbard $U$ used in the simulation. We also discuss outcomes of recently proposed combinations of k-dependent FLEX with DMFT.
