description: Diabetes is the most frequent metabolic disorder during pregnancy. Its development is related to multiple factors and is associated with maternal and perinatal adverse effects. This study aims to determine the association of nutritional patterns, anthropometric and sociodemographic aspects with gestational diabetes mellitus (GDM), and perinatal results. A prospective cohort study was conducted on 237 pregnant women with the application of questionnaires: structured, global physical activity (GPAQ), 24-hour recall, and review of the perinatal medical history. Exploratory factor analysis was performed to determine the nutritional patterns; descriptive, bivariate, and multivariate analysis between the groups of patients with GDM and without GDM in users of the Centro de salud de Puengasí 2, and the Hospital Gineco Obstetrico Isidro Ayora in the city of Quito, from January to September 2021. Three nutritional patterns were identified in pregnant women. There was a difference in the variables, such as age, years of study, previous pregnancies, weight, and body mass index (BMI) for gestational age at the beginning of pregnancy between pregnant women diagnosed with GDM and those without GDM. Multivariate analysis confirms the association of GDM with BMI for gestational age at the start of pregnancy RR 0.293 (0.08-0.970) and passive smoking RR 0.037 (0.00196-0.701). No association with nutritional patterns was found. In conclusion,the affinity for nutritional patterns and physical activity does not show an association with GDM. The association between BMI for gestational age at the beginning of pregnancy and passive smoking with GDM is confirmed.
Formality of Sinha's cosimplicial model for long knots spaces and the Gerstenhaber algebra structure of homology

description: Sinha has constructed a cosimplicial space X for a fixed integer N. One of his main result states that for N > 3, X is a cosimplicial model for the space of long knots (modulo immersions). On the other hand, Lambrechts, Turchin and Volic showed that for N > 3 the homology Bousfield-Kan spectral sequence associated to Sinha's cosimplicial space collapses at the page 2 rationally. Their approach consists first to prove the formality of some other diagrams approximating X and next deduce the collapsing result. In this paper, we prove directly the formality of Sinha's cosimplicial space and this allows us to construct a very short proof of the collapsing result for N > 2. Moreover, we prove that the isomorphism between the page 2 and the rational homology of the space of long knots modulo immersions is of Poisson algebras, when N > 3.

description: This article studies the smoothness of conformal mappings between two Riemannian manifolds whose metric tensors have limited regularity. We show that any bi-Lipschitz conformal mapping or $1$-quasiregular mapping between two manifolds with $C^r$ metric tensors ($r > 1$) is a $C^{r+1}$ conformal (local) diffeomorphism. This result was proved in [12, 27, 33], but we give a new proof of this fact. The proof is based on $n$-harmonic coordinates, a generalization of the standard harmonic coordinates that is particularly suited to studying conformal mappings. We establish the existence of a $p$-harmonic coordinate system for $1 < p < \infty$ on any Riemannian manifold.

description: We consider unimodular random rooted trees (URTs) and invariant forests in Cayley graphs. We show that URTs of bounded degree are the same as the law of the component of the root in an invariant percolation on a regular tree. We use this to give a new proof that URTs are sofic, a result of Elek. We show that ends of invariant forests in the hyperbolic plane converge to ideal boundary points. We also prove that uniform integrability of the degree distribution of a family of finite graphs implies tightness of that family for local convergence, also known as random weak convergence.

Bayesian Structure Learning in Sparse Gaussian Graphical Models

description: Decoding complex relationships among large numbers of variables with relatively few observations is one of the crucial issues in science. One approach to this problem is Gaussian graphical modeling, which describes conditional independence of variables through the presence or absence of edges in the underlying graph. In this paper, we introduce a novel and efficient Bayesian framework for Gaussian graphical model determination which is a trans-dimensional Markov Chain Monte Carlo (MCMC) approach based on a continuous-time birth-death process. We cover the theory and computational details of the method. It is easy to implement and computationally feasible for high-dimensional graphs. We show our method outperforms alternative Bayesian approaches in terms of convergence, mixing in the graph space and computing time. Unlike frequentist approaches, it gives a principled and, in practice, sensible approach for structure learning. We illustrate the efficiency of the method on a broad range of simulated data. We then apply the method on large-scale real applications from human and mammary gland gene expression studies to show its empirical usefulness. In addition, we implemented the method in the R package BDgraph which is freely available at http://CRAN.R-project.org/package=BDgraph

description: We have applied the coupled-channel complex scaling method (ccCSM) to K^{bar}N-πY system. One advantage of ccCSM is that resonant states as well as scattering states can be treated in the same framework. For the interactions in the system, we have constructed a meson-baryon potential-matrix by basing on the chiral SU(3) theory and respecting the K^{bar}N scattering length obtained in the Martin's analysis. For future purpose to apply it more complicated system such as K^{bar}NN, we adopt a local Gaussian form in the r-space. We have investigated both the non-relativistic (NR) and the semi-relativistic (SR) kinematics. In the SR case, two types of the potentials are obtained. To test the constructed potentials, we have calculated scattering amplitudes and searched resonances. One resonance pole, corresponding to Λ(1405), is found in isospin I=0 system around (1419, -20) MeV ((1425, -25) or (1419, -13) MeV) on complex-energy plane with the NR (SR) kinematics. Mean distance between meson and baryon in the resonant state is 1.3 - i0.3 fm (1.2 - i0.5 fm) for NR (SR), in which the states are treated as Gamow states. In addition, we have observed a signature of another pole in lower-energy region involving large decay width, although they are unstable against the change of scaling angle θ. This may correspond to the lower pole of the double-pole of Λ(1405) discussed in literature to date.

description: Hematopoietic Stem Cells (HSCs) are cells that have the ability to self-renewal and differentiate into all of hematopoietic lineages. The lack of donors and unavailable efficient protocols for ex vivo expansion of HSCs, are obstacles in successful cell therapies. MicroRNAs (also refer as miRNAs or miRs) have significant roles in hematopoiesis; they can effect on HSCs expansion, maintaining undifferentiated state, self-renewal and differentiation. Recently attentions have been given to these small regulatory molecules to utilize them in order to expand HSCs. Using bioinformatics analysis we identified Sall4 as putative target of miR-15b and miR-219-5p. Relative expression levels of miRNAs and Sall4 were evaluated by qRT-PCR. Here we show 247-fold and 4.2-fold increasing Sall4 expression level compared to control group in CD34+ cells nucleofected by anti-miR-15b and anti-miR-219-5p, respectively. These data showed that anti-miR-15b can promote clonogenic capacity of HSCs and also we found that miR-15b alone was able to increase the number of CD34+HSCs in vitro by more than 2 fold by targeting Sall4. Moreover, level of CD34 marker in HSCs nucleofected by anti-miR-15b increased more than 50 %. Our analysis showed no statistically difference in mRNA level of Sall4 after nucleofection of anti-miR-219-5p. Sall4 is a factor capable of enhancing HSC expansion significantly. We demonstrated that inhibition of miR-15b can enhance ex vivo expansion of UCB-derived HSCs and also expression of Sall4 allowed expansion and preserve self- renewal of CD34+ HSCs.

description: The current attempt is aimed to honor the first centennial of Johannes Diderik van der Waals (VDW) awarding Nobel Prize in Physics. The VDW theory of ordinary fluids is reviewed in the first part of the paper, where special effort is devoted to the equation of state and the law of corresponding states. In addition, a few mathematical features involving properties of cubic equations are discussed, for appreciating the intrinsic beauty of the VDW theory. A theory of astrophysical fluids is shortly reviewed in the second part of the paper, grounding on the tensor virial theorem for two-component systems, and an equation of state is formulated with a convenient choice of reduced variables. Additional effort is devoted to particular choices of density profiles, namely a simple guidance case and two cases of astrophysical interest. The related macroisothermal curves are found to be qualitatively similar to VDW isothermal curves below the critical threshold and, for sufficiently steep density profiles, a critical macroisothermal curve exists, with a single horizontal inflexion point. Under the working hypothesis of a phase transition (assumed to be gas-stars) for astrophysical fluids, similar to the vapour-liquid phase transition in ordinary fluids, the location of gas clouds, stellar systems, galaxies, cluster of galaxies, on the plane scanned by reduced variables, is tentatively assigned. A brief discussion shows how van der Waals' two great discoveries, namely a gas equation of state where tidal interactions between molecules are taken into account, and the law of corresponding states, related to microcosmos, find a counterpart with regard to macrocosmos. In conclusion, after more than a century since the awarding of the Nobel Prize in Physics, van der Waals' ideas are still valid and helpful to day for a full understanding of the universe.

Abstract

Large websites are difficult to evaluate for Web Accessibility compliance due to the shear number of pages, the inaccuracy of current Web evaluation engines, and the W3C stated need to include human evaluators within the testing regime. This makes evaluating large websites all-but technically unfeasible. Therefore, sampling of the pages becomes a critical first step in the evaluation process. Current methods rely on drawing random samples, best guess samples, or convenience samples. In all cases the evaluation results cannot be trusted because the underlying structure and nature of the site are not known; they are missing `website demographics'. By understanding the quantifiable statistics of a given population of pages we are better able to decide on the coverage we need for a full review, as well as the sample we need to draw in order to enact an evaluation. Our solution is to crawl a website comparing, and then clustering, the pages discovered based on Document Object Model block level similarity. This technique can be useful in reducing very large sites to a more manageable size, and allowing an 80% coverage by evaluating between approx 0.1-4% of pages; additionally, by refining our clustering algorithm, we discuss how this could be reduced further.

description: The sample sizes of the two most recent (2011 and 2013) Gulf of Alaska bottom trawl surveys were reduced by 20% and 33% (to 670 and 548 from 825 stations), respectively because of lack of funding and logistical reasons. In this study we examine the potential impact these sample size reductions has on the precision of the biomass estimates of 11 common species assessed by this survey. Surveys of sample sizes ranging from 300 to 825 stations were simulated by randomly sampling stations without replacement from the 2007 Gulf of Alaska survey. The coefficient of variance was plotted against sample size for each of the 11 species, and the rate of decline of the slope of the fitted curve was used to determine whether the reduced sample sizes of the two most recent surveys resulted in adequate precision. A threshold value of the slope (70% of its value at N = 300) was used to decide whether the reduced sample sizes of the 2011 and 2013 surveys were adequate for each species. The sample size of the 2013 (N = 548) survey resulted in none of the 11 species meeting the threshold, suggesting that the sample size that year was too low. In contrast, 3 species met the threshold at the sample size of the 2011 survey (N = 670) and 10 species met the threshold for a traditional full-scale survey (N = 825).

Platonic hyperbolic monopoles

Year: 2012
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We construct a number of explicit examples of hyperbolic monopoles, with various charges and often with some platonic symmetry. The fields are obtained from instanton data in four-dimensional Euclidean space that are invariant under a circle action, and in most cases the monopole charge is equal to the instanton charge. A key ingredient is the identification of a new set of constraints on ADHM instanton data that are sufficient to ensure the circle invariance. Unlike for Euclidean monopoles, the formulae for the squared Higgs field magnitude in the examples we construct are rational functions of the coordinates. Using these formulae, we compute and illustrate the energy density of the monopoles. We also prove, for particular monopoles, that the number of zeros of the Higgs field is greater than the monopole charge, confirming numerical results established earlier for Euclidean monopoles. We also present some one-parameter families of monopoles analogous to known scattering events for Euclidean monopoles within the geodesic approximation.

description: This paper was originally published in June 2013 in JFM (vol. 725). There was one result concerning an expression of viscous dissipation in convective flows and a second result on the condition of applicability of the anelastic liquid equation ($γ- 1 \ll 1$). We then found that this second result was wrong and the explanation why this is so was published as a corrigendum in July 2014 in JFM (vol. 751). In a few words, the origin of the error is that we have derived an expression for dissipation in the framework of the exact equations and subsequently used it in the framework of the anelastic models. Here we have included the original article, followed by its corrigendum.

description: The North Pacific Groundfish and Halibut Observer Program is a potentially huge source of coral location data that could provide much needed information on high diversity hotspots and vulnerable marine ecosystems. We implemented a pilot project in 2012 and 2013 with experienced fisheries observers to improve data collection on coral bycatch by the Alaskan commercial fishing fleet. Observers were provided with coral identification training in a classroom setting and taxonomic field guides and instructed to collect and identify each unique coral taxon encountered when possible. Specimens were frozen and shipped to the Alaska Fisheries Science Center where they were identified. Specimen identifications were used to gauge the potential capabilities and limitations of the observers and resolve problems with coral identification training and collection protocols. Over 240 observers received training during this project and they observed 20,945 gear hauls during the study period. Trained observers reported corals in less than 10% of sampled hauls, and more than 70% of reported corals were sea pens and sea whips (pennatulaceans). Samples collected by observers indicate that identification accuracy was relatively low, with 74% of corals correctly identified to the requested taxonomic level. Misidentified specimens included a variety of benthic invertebrates such as hydroids, bryozoans, and sponges. The highly variable success rate among observers and relatively low overall accuracy rate indicates that the level of training was insufficient to provide consistently reliable results at the requested level of taxonomy. Long-term implementation of a coral identification protocol, like the one tested for this project, would require a significant investment of training resources.

description: Arbitrary regularization dependent parameters in Quantum Field Theory are usually fixed on symmetry or phenomenology grounds. We verify that the quadratically divergent behavior responsible for the lack of naturalness in the Standard Model (SM) is intrinsically arbitrary and regularization dependent. While quadratic divergences are welcome for instance in effective models of low energy QCD, they pose a problem in the SM treated as an effective theory in the Higgs sector. Being the very existence of quadratic divergences a matter of debate, a plausible scenario is to search for a symmetry requirement that could fix the arbitrary coefficient of the leading quadratic behavior to the Higgs boson mass to zero. We show that this is possible employing consistency of scale symmetry breaking by quantum corrections. Besides eliminating a fine-tuning problem and restoring validity of perturbation theory, this requirement allows to construct bounds for the Higgs boson mass in terms of $δm^2/m^2_H$ (where $m_H$ is the renormalized Higgs mass and $δm^2$ is the 1-loop Higgs mass correction). Whereas $δm^2/m^2_H<1$ (perturbative regime) in this scenario allows the Higgs boson mass around the current accepted value, the inclusion of the quadratic divergence demands $δm^2/m^2_H$ arbitrarily large to reach that experimental value.

description: Urban form has been empirically demonstrated to be of scaling invariance and can be described with fractal geometry. However, the rational range of fractal dimension value and the relationships between various fractal indicators of cities are not yet revealed in theory. By mathematical deduction and transformation (e.g. Fourier transform), I find that scaling analysis, spectral analysis, and spatial correlation analysis are all associated with fractal concepts and can be integrated into a new approach to fractal analysis of cities. This method can be termed 3S analyses of urban form. Using the 3S analysis, I derived a set of fractal parameter equations, by which different fractal parameters of cities can be linked up with one another. Each fractal parameter has its own reasonable extent of values. According to the fractal parameter equations, the intersection of the rational ranges of different fractal parameters suggests the proper scale of the fractal dimension of urban patterns, which varies from 1.5 to 2. The fractal dimension equations based on the 3S analysis and the numerical relationships between different fractal parameters are useful for geographers to understand urban evolution and potentially helpful for future city planning.

description: Communication forms the basis of biological interactions. While the use of a single communication mechanism (for example visual communication) by a species is quite well understood, in nature the majority of species communicate via multiple mechanisms. Here, I review some mathematical results on the unexpected behaviors that can be observed in biological aggregations where individuals interact with each other via multiple communication mechanisms.

description: Quantum fluctuations give rise to van der Waals and Casimir forces that dominate the interaction between electrically neutral objects at sub-micron separations. Under the trend of miniaturization, such quantum electrodynamical effects are expected to play an important role in micro- and nano-mechanical devices. Nevertheless, utilization of Casimir forces on the chip level remains a major challenge because all experiments so far require an external object to be manually positioned close to the mechanical element. Here, by integrating a force-sensing micromechanical beam and an electrostatic actuator on a single chip, we demonstrate the Casimir effect between two micromachined silicon components on the same substrate. A high degree of parallelism between the two near-planar interacting surfaces can be achieved because they are defined in a single lithographic step. Apart from providing a compact platform for Casimir force measurements, this scheme also opens the possibility of tailoring the Casimir force using lithographically defined components of non-conventional shapes.

description: In recent years Alaska's sport fisheries have undergone substantial changes, particularly in the management of the Pacific halibut (Hippoglossus stenolepis) charter fishery. As a result of these regulatory changes, participation in the charter sector Pacific halibut fishery has been capped with a limited entry program and charter vessel operators in some areas have been subject to size restrictions and bag limits on the catch of Pacific halibut during guided trips. Additionally, a halibut catch sharing plan (CSP) formalizing the process of allocating catch between the commercial and charter sectors was implemented in January 2014 (78 FR 39121)

Multiplicative formality of operads and Sinha's spectral sequence for long knots

description: Lambrechts, Turchin and Volić proved the Bousfield-Kan type rational homology spectral sequence associated to the $d$-th Kontsevich operad collapses at $E^2$-page if $d\geq 4$. The key of their proof is formality of the operad. In this paper, we simplify their proof using a model category of operads. As byproducts we obtain two new consequences. One is collapse of the spectral sequence in the case of $d=3$ (and the coefficients being rational numbers). The other says there is no non-trivial extension for the Gerstenhaber algebra structure on the spectral sequence.

description: The eastern Bering Sea bottom trawl survey has been conducted annually since 1975 by the Resource Assessment and Conservation Engineering Division of the Alaska Fisheries Science Center, National Marine Fisheries Service. The purpose of this survey is to collect data on the distribution and abundance of crab, groundfish, and other benthic resources in the eastern Bering Sea. These data are used to estimate population abundances for the management of commercially important species in the region. In 2013, 376 standard stations were sampled on the eastern Bering Sea shelf.
Representations of Lie Algebras by non-Skewselfadjoint Operators in Hilbert Space

description: We study non-selfadjoint representations of a finite dimensional real Lie algebra $\fg$. To this end we embed a non-selfadjoint representation of $\fg$ into a more complicated structure, that we call a $\fg$-operator vessel and that is associated to an overdetermined linear conservative input/state/output system on the corresponding simply connected Lie group $\fG$. We develop the frequency domain theory of the system in terms of representations of $\fG$, and introduce the joint characteristic function of a $\fg$-operator vessel which is the analogue of the classical notion of the characteristic function of a single non-selfadjoint operator. As the first non-commutative example, we apply the theory to the Lie algebra of the $ax+b$ group, the group of affine transformations of the line.

description: The world faces a massive gender gap in science. In Ethiopia, only ~ 13% of all scientists are women, and this number becomes even lower when considering fundamental sciences. In addition, if able to continue with their studies at the secondary school level, girls avoid choosing science, technology, engineering, and mathematics (STEM) fields mainly due to the lack of support, information, and role models. This becomes even more evident when going to remote and rural areas, where 80% of the Ethiopian population lives. The SciGirls project aims to improve in the long term the gender gap in science and the current lack of girls in STEM by empowering secondary school girls from rural areas and their female science teachers through astronomy and its multidisciplinarity. To do so, we organised a strong capacity-building workshop for 30 participants from different regions of Ethiopia, with an aim to build the future advocates of STEM in rural areas through trained girls and female teachers. The SciGirls is one of the OAD-IAU 2022-funded projects, with the strong support of the Ethiopian Space Science and Geospatial Institute. Through this talk, we will share our experience, and give more details about the project and its future developments. The workshop organised was extremely successful and through our experience, we would like to motivate others to use the SciGirls as a pilot project and model in other countries and areas.
A Search for Correlation of Ultra-High Energy Cosmic Rays with IRAS-PSCz and 2MASS-6dF Galaxies

description: We study the arrival directions of 69 ultra-high energy cosmic rays (UHECRs) observed at the Pierre Auger Observatory (PAO) with energies exceeding 55 EeV. We investigate whether the UHECRs exhibit the anisotropy signal expected if the primary particles are protons that originate in galaxies in the local universe, or in sources correlated with these galaxies. We cross-correlate the UHECR arrival directions with the positions of IRAS-PSCz and 2MASS-6dF galaxies taking into account particle energy losses during propagation. This is the first time that the 6dF survey is used in a search for the sources of UHECRs and the first time that the PSCz survey is used with the full 69 PAO events. The observed cross-correlation signal is larger for the PAO UHECRs than for 94% (98%) of realisations from an isotropic distribution when cross-correlated with the PSCz (6dF). On the other hand the observed cross-correlation signal is lower than that expected from 85% of realisations, had the UHECRs originated in galaxies in either survey. The observed cross-correlation signal does exceed that expected by 50% of the realisations if the UHECRs are randomly deflected by intervening magnetic fields by 5 degrees or more. We propose a new method of analysing the expected anisotropy signal, by dividing the predicted UHECR source distribution into equal predicted flux radial shells, which can help localise and constrain the properties of UHECR sources. We find that the 69 PAO events are consistent with isotropy in the nearest of three shells we define, whereas there is weak evidence for correlation with the predicted source distribution in the two more distant shells in which the galaxy distribution is less anisotropic.
