increasing regular physical activity in adults with cardiometabolic risk factors
Creators: name: Liamina, Anastasia
Publisher: name: No Publisher Supplied
Year: 2023

description: Purpose of Project: Metabolic syndrome is a condition characterized by the presence of at least three of the following: abdominal obesity, elevated triglyceride levels, low levels of high-density lipoproteins (HDL), high fasting blood sugar, or increased blood pressure. Management of metabolic syndrome often requires lifestyle modifications such as a healthy diet and regular exercise.The purpose of this quality improvement project was to increase regular physical activity in adults with cardiometabolic risk factors. Methods: This project included adult patients (18 years and older) with at least one cardiometabolic risk factor that are able to exercise/walk. Counseling on the benefits of physical activity, self-monitoring (via pedometer and physical activity logs), and weekly follow-ups has been provided to 6 participants. The participants have been instructed to record a daily number of steps and minutes of physical activity using a physical activity log for 1 month. Results: Data analysis for the project was focused on the total number of steps and minutes of physical activity as compared pre-and post-intervention. The increase in minutes of activity per week pre and post intervention was statistically significant with p value of 0.0448. The increase in minutes of activity during weeks 1-4 was statistically significant with p value of 0.019. Results showed that education provided to participants together with handouts and fitness tracker increased their physical activity over a span of 4 weeks. Implications for practice: The intervention introduced a more structured approach to the way patients in the clinic were counseled on physical activity. Further research is needed to confirm if the increase in physical activity reduced participants’ cardiometabolic risk factors.

description: The implementation of computational sensing strategies often faces calibration problems typically solved by means of multiple, accurately chosen training signals, an approach that can be resource-consuming and cumbersome. Conversely, blind calibration does not require any training, but corresponds to a bilinear inverse problem whose algorithmic solution is an open issue. We here address blind calibration as a non-convex problem for linear random sensing models in which we aim to recover an unknown signal from its projections on sub-Gaussian random vectors, each of which is subject to an unknown multiplicative factor (gain). To solve this optimisation problem we resort to projected gradient descent starting from a suitable initialisation. An analysis of this algorithm allows us to show that it converges to the global optimum provided a sample complexity requirement is met, i.e., relating convergence to the amount of information collected during the sensing process. Finally, we present some numerical experiments in which our algorithm allows for a simple solution to blind calibration of sensor gains in computational sensing applications.

description: Coupling a many-body-localized system to a dissipative bath necessarily leads to delocalization. Here, we investigate the nature of the ensuing relaxation dynamics and the information it holds on the many-body-localized state. We formulate the relevant Lindblad equation in terms of the local integrals of motion of the underlying localized Hamiltonian. This allows to map the quantum evolution deep in the localized state to tractable classical rate equations. We consider two different types of dissipation relevant to systems of ultra-cold atoms: dephasing due to inelastic scattering on the lattice lasers and particle loss. Only the latter mechanism shows a pronounced effects of interactions on the relaxation of observables.

description: Design master students often focus on delivering creative, resourceful and unique ideas on the design problems at hand while encountering periods of uncertainty, such as dealing with stress, anxiety and depression. Additionally, some design practices do not propose to pause and wonder what will happen if students take time to explore and comprehend their emotions, as recognizing and understanding emotions is sometimes challenging. However, pursuing reflective practices could foster students’ confidence, facilitating self-expression and creativity. To explore this area, I conducted an immersive, exploratory action-research dialogue that questioned how design master students could nourish their emotional well-being under periods of uncertainty. The findings indicate that bringing emotions to a tactile form enables students to experience a sense of well-being and cultivate confidence.

description: We study the geometry of gauge fluxes in four-dimensional F-theory vacua with gauge group SU(3)xSU(2)xU(1)xU(1) and its implications for phenomenology. The models are defined by a previously introduced class of elliptic fibrations whose fibre is given as a cubic hypersurface in ${\rm Bl}_2{\mathbb P}^2$, with the non-abelian gauge group factors SU(3)xSU(2) engineered torically via the top construction. To describe gauge fluxes on these fibrations we provide a classification of the primary vertical middle cohomology group in a fashion valid for any choice of base space. Using the ideal theoretic technique of primary decomposition we compute the cohomology classes of the matter surfaces associated with states charged under the non-abelian gauge group. These expressions allow us to interpret the cancellation of the pure and mixed non-abelian anomalies geometrically as a result of the general form of the matter surfaces, without reference to a specific type of gauge flux. Explicit results for the chiral indices of all matter states are obtained in terms of intersection numbers of the base and can be directly applied to any choice of base consistent with the fibration. As a demonstration we scan for globally consistent F-theory vacua on $\mathbb P^3$, ${\rm Bl}_1\mathbb P^3$ and ${\rm Bl}_2 \mathbb{P}^3$, and find a globally consistent flux configuration with the chiral Standard Model spectrum plus an extra triplet pair, which may be lifted by a recombination process.

description: Starting with the pioneering work of Ein and Lazarsfeld restrictions on values of Seshadri constants on algebraic surfaces have been studied by many authors. In the present note we show how approximation involving continued fractions combined with recent results of Kuronya and Lozovanu on Okounkov bodies of line bundles on surfaces lead to effective statements considerably restricting possible values of Seshadri constants. These results in turn provide strong aditional evidence to a conjecture governing the Seshadri constants on algebraic surfaces with Picard number 1.

description: A Reissner-Nordström black hole (BH) is superradiantly unstable against spherical perturbations of a charged scalar field, enclosed in a cavity, with frequency lower than a critical value. We use numerical relativity techniques to follow the development of this unstable system -- dubbed a charged BH bomb -- into the non-linear regime, solving the full Einstein--Maxwell--Klein-Gordon equations, in spherical symmetry. We show that: $i)$ the process stops before all the charge is extracted from the BH; $ii)$ the system settles down into a hairy BH: a charged horizon in equilibrium with a scalar field condensate, whose phase is oscillating at the (final) critical frequency. For low scalar field charge, $q$, the final state is approached smoothly and monotonically. For large $q$, however, the energy extraction overshoots and an explosive phenomenon, akin to a $bosenova$, pushes some energy back into the BH. The charge extraction, by contrast, does not reverse.

The existence of a global fundamental solution for homogeneous Hörmander operators via a global lifting method

description: We prove the existence of a global fundamental solution $Γ(x;y)$ (with pole $x$) for any Hörmander operator $\mathcal{L}=\sum_{i=1}^m X_i^2$ on $\mathbb{R}^n$ which is $δ$-homogeneous of degree $2$. By means of a global Lifting method for homogeneous operators proved by Folland in [On the Rothschild-Stein lifting theorem, Comm. PDEs, 1977], there exists a Carnot group $\mathbb{G}$ and a polynomial surjective map $π:\mathbb{G}\to \mathbb{R}^n$ such that $\mathcal{L}$ is $π$-related to a sub-Laplacian $\mathcal{L}_{\mathbb{G}}$ on $\mathbb{G}$. We show that it is always possible to perform a (global) change of variable on $\mathbb{G}$ such that the lifting map $π$ becomes the projection of $\mathbb{G}\equiv \mathbb{R}^n\times\mathbb{R}^p$ onto $\mathbb{R}^n$. If $Γ_{\mathbb{G}}(x,{x}';y,{y}')$ ($x,{x}'\in\mathbb{R}^n$; $y,{y}'\in\mathbb{R}^p$) is the fundamental solution of $\mathcal{L}_{\mathbb{G}}$, we show that $Γ_{\mathbb{G}}(x,0;y,{y}')$ is always integrable w.r.t. ${y}'\in \mathbb{R}^p$, and its integral is a fundamental solution for $\mathcal{L}$.

description: We present a first QCD analysis of next-to-next-leading-order (NNLO) contributions of the spin-dependent parton distribution functions (PPDFs) in the nucleon and their uncertainties using the Jacobi polynomial approach. Having the NNLO contributions of the quark-quark and gluon-quark splitting functions in perturbative QCD (Nucl. Phys. B 889 (2014) 351-400), one can obtain the evolution of longitudinally polarized parton densities of hadrons up to NNLO accuracy of QCD. A very large sets of recent and up-to-date experimental data of spin structure functions of the proton $g_1^p$, neutron $g_1^n$, and deuteron $g_1^d$ have been used in this analysis. The predictions for the NNLO calculations of the polarized parton distribution functions as well as the proton, neutron and deuteron polarized structure functions are compared with the corresponding results of the NLO approximation. We form a mutually consistent set of polarized PDFs due to the inclusion of the most available experimental data including the recently high-precision measurements from {\tt COMPASS16} experiments (Phys. Lett. B 753 (2016) 18-28). We have performed a careful estimation of the uncertainties using the most common and practical method, the Hessian method, for the polarized PDFs originating from the experimental errors. The proton, neutron and deuteron structure functions and also their first moments, $Γ^{\rm p, n, d}$, are in good agreement with the experimental data at small and large momentum fraction of $x$. We will discuss how our knowledge of spin-dependence structure functions can improve at small and large value of $x$ by the recent {\tt COMPASS16} measurements at CERN, the {\tt PHENIX} and {\tt STAR} measurements at RHIC, and at the future proposed colliders such as Electron-Ion collider (EIC).

description: It has been shown by Remmen and Carroll that, for a model universe which contains only a kinetically canonical scalar field minimally coupled to gravity it is possible to choose 'special coordinates' to describe a two-dimensional effective phase space. The special, non-canonical, coordinates are $ϕ$,$\dotϕ$ and the ability to describe an effective phase space with these coordinates empowers the common usage of $ϕ-\dotϕ$ as the space to define inflationary initial conditions. This paper extends the result to the full Horndeski action. The existence of a two-dimensional effective phase space is shown for the general case. Subsets of the Horndeski action, relevant to cosmology are considered as particular examples to highlight important aspects of the procedure.

description: We present a method for the numerical calculation of derivatives of functions of general complex matrices. The method can be used in combination with any algorithm that evaluates or approximates the desired matrix function, in particular with implicit Krylov-Ritz-type approximations. An important use case for the method is the evaluation of the overlap Dirac operator in lattice Quantum Chromodynamics (QCD) at finite chemical potential, which requires the application of the sign function of a non-Hermitian matrix to some source vector. While the sign function of non-Hermitian matrices in practice cannot be efficiently approximated with source-independent polynomials or rational functions, sufficiently good approximating polynomials can still be constructed for each particular source vector. Our method allows for an efficient calculation of the derivatives of such implicit approximations with respect to the gauge field or other external parameters, which is necessary for the calculation of conserved lattice currents or the fermionic force in Hybrid Monte-Carlo or Langevin simulations. We also give an explicit deflation prescription for the case when one knows several eigenvalues and eigenvectors of the matrix being the argument of the differentiated function. We test the method for the two-sided Lanczos approximation of the finite-density overlap Dirac operator on realistic $SU(3)$ gauge field configurations on lattices with sizes as large as $14\times14^3$ and $6\times18^3$.

description: Gamma-ray experiments seeking to detect evidence of dark matter annihilation in dwarf spheroidal galaxies require knowledge of the distribution of dark matter within these systems. We analyze the effects of flattening on the annihilation (J) and decay (D) factors of dwarf spheroidal galaxies with both analytic and numerical methods. Flattening has two consequences: first, there is a geometric effect as the squeezing (or stretching) of the dark matter distribution enhances (or diminishes) the J-factor; second, the line of sight velocity dispersion of stars must hold up the flattened baryonic component in the flattened dark matter halo. We provide analytic formulae and a simple numerical approach to estimate the correction to the J- and D-factors required over simple spherical modeling. The formulae are validated with a series of equilibrium models of flattened stellar distributions embedded in flattened dark-matter distributions. We compute corrections to the J- and D-factors for the Milky Way dwarf spheroidal galaxies under the assumption that they are all prolate or all oblate and find that the hierarchy of J-factors for the dwarf spheroidals is slightly altered (typical correction factors for an ellipticity of $0.4$ are $0.75$ for the oblate case and $1.6$ for the prolate case). We demonstrate that spherical estimates of the D-factors are very insensitive to the flattening and introduce uncertainties significantly less than the uncertainties in the D-factors from the other observables for all the dwarf spheroidals (for example, ${}^{+10\mathrm{\,percent}}_{-3\mathrm{\,percent}}$ for a typical ellipticity of $0.4$). We conclude by investigating the spread in correction factors produced by triaxial figures and provide uncertainties in the J-factors for the dwarf spheroidals using different physically-motivated assumptions for their intrinsic shape and axis alignments.

description: We present the widest-field resolved stellar map to date of the closest ($D\sim3.8$ Mpc) massive elliptical galaxy NGC 5128 (Centaurus A; Cen A), extending out to a projected galactocentric radius of $\sim150$ kpc. The dataset is part of our ongoing Panoramic Imaging Survey of Centaurus and Sculptor (PISCeS) utilizing the Magellan/Megacam imager. We resolve a population of old red giant branch stars down to $\sim1.5$ mag below the tip of the red giant branch, reaching surface brightness limits as low as $μ_{V,0}\sim32$ mag arcsec$^{-2}$. The resulting spatial stellar density map highlights a plethora of previously unknown streams, shells, and satellites, including the first tidally disrupting dwarf around Cen A (CenA-MM-Dw3), which underline its active accretion history. We report 13 previously unknown dwarf satellite candidates, of which 9 are confirmed to be at the distance of Cen A (the remaining 4 are not resolved into stars), with magnitudes in the range $M_V=-7.2$ to $-13.0$, central surface brightness values of $μ_{V,0}=25.4-26.9$ mag arcsec$^{-2}$, and half-light radii of $r_h=0.22-2.92$ kpc. These values are in line with Local Group dwarfs but also lie at the faint/diffuse end of their distribution; interestingly, CenA-MM-Dw3 has similar properties to the recently discovered ultra-diffuse galaxies in Virgo and Coma. Most of the new dwarfs are fainter than the previously known Cen A satellites. The newly discovered dwarfs and halo substructures are discussed in light of their stellar populations, and they are compared to those discovered by the PAndAS survey of M31.

Improving influenza vaccination rates in the orthodox Jewish community

description: Purpose of Project: The seasonal influenza vaccine is the gold standard public health tool for combatting the seasonal spread of influenza in the community, which leads to significant illness and death. Despite widespread availability and proven efficacy, uptake of the vaccine remains low due to vaccine hesitancy. The purpose of the project was to increase rates of seasonal influenza vaccination in the Orthodox Jewish community, which is known for high rates of vaccine hesitancy.Methodology: This project was implemented in a single, high volume urgent care clinic with a predominantly Orthodox Jewish patient population. A practice protocol that focused on steps to increase vaccine uptake was created. The protocol utilized the 5 As approach, which is an evidence-based health behavior change tool that involves 5 key steps: ask, advise, assess, assist, and arrange.Healthcare providers and staff were trained to use the 5 As approach to encourage patients to get vaccinated. Fifty (50) patient charts were randomly sampled from October 2021 (pre intervention) and the same amount of patient charts (50) were randomly selected from October 2022 (post intervention). The rates of vaccination (pre- and post-intervention) were compared using the chi-square test for independence. Results: During October 2021, out of 50 randomly selected patients (charts), 22 received influenza vaccination. During October 2022, 34 patients got vaccinated. This post-intervention increase in vaccination rates was statistically significant, with a p-value of 0.015629. Implications for Practice: This quality improvement protocol is low-cost and easy to implement. It was found to be effective in improving vaccine uptake and can be implemented broadly by primary and urgent care practices to combat misinformation and increase influenza vaccine uptake.

description: This piece is inspired by the premise of Closeness and Distance. In order to capture this theme I turned to Descartes’ Meditations on First Philosophy, in which he examines, through a lens of doubt, the three faculties of reason in determining what actually exists. One of the main features of this text is that Descartes is doing all of this ‘out of body’ thinking and rebuilding of all of his beliefs from an armchair in his study. Descartes began this experiment with the belief that he didn’t need any connection with the world and environment outside of his own mind in order to attain the truth about existence. To me this demonstrates a fascinating example of both closeness and distance – closeness to one’s own mind and assurance in it’s ability to internally discover absolute truth; and distance for the measure you have to push your mental capacity to in order to strip away all of your own beliefs in order to rebuild them within a frame work of that absolute truth. This second point, of course, also creates a distance between the meditator and the rest of the world.

description: By making use of a low-energy effective model of Weyl semimetals, we show that the Fermi arc transport is dissipative. The origin of the dissipation is the scattering of the surface Fermi arc states into the bulk of the semimetal. It is noticeable that corresponding scattering rate is nonzero and can be estimated even in a perturbative theory, although in general the reliable calculations of transport properties necessitate a nonperturbative approach. Nondecoupling of the surface and bulk sectors in the low-energy theory of Weyl semimetals invalidates the usual argument of a nondissipative transport due to one-dimensional arc states. This property of Weyl semimetals is in drastic contrast to that of topological insulators, where the decoupling is protected by a gap in the bulk. Within the framework of the linear response theory, we obtain an approximate result for the conductivity due to the Fermi arc states and analyze its dependence on chemical potential, temperature, and other parameters of the model.

description: The advent of social media has spawned an entire digital ecosystem for communication and information management. This change has had a profound effect on science and the way its results are published and disseminated. Twitter, Wikipedia, and news outlets are now the visible heads of an extensive number of channels for scientific communication, integrating and making the discourse and dissemination of scientific results visible to society as a whole. This has led to the exploration of how science is consumed in such environments and the attention it captures beyond the realm of academia. However, a lack of depth and exploitation of the media studied beyond counting mentions of scholarly outputs has been identified, along with putting the activity around science into greater context. There also exists the unexplored platforms and limited adaptation of traditional methods of scientometrics for the quantitative study of science. This thesis aims to address these challenges to delve into the potential of massive social media data and the heterogeneity of social media for the study of science by combining data science and scientometrics. As a result, proposals for conceptual and methodological frameworks for the use and mapping of social media data have been developed. For this purpose, classic scientometric techniques have been adapted for social network analysis, and new methods have been proposed for the creation of scientific maps that combine social and semantic information. This allows the identification of knowledge structures established through social activity and the identification of cognitive communities of social actors. Furthermore, the methodological proposals have been put into practice through case studies and large-scale studies to validate them and provide novel results on the discussion and dissemination of science on Twitter and Wikipedia, particularly in comparison to academia.

description: Detecting a deviation from a featureless primordial power spectrum of fluctuations would give profound insight into the physics of the primordial Universe. Depending on their nature, primordial features can either provide direct evidence for the inflation scenario or pin down details of the inflation model. Thus far, using the cosmic microwave background (CMB) we have only been able to put stringent constraints on the amplitude of features, but no significant evidence has been found for such signals. Here we explore the limit of the experimental reach in constraining such features using 21 cm tomography at high redshift. A measurement of the 21 cm power spectrum from the Dark Ages is generally considered as the ideal experiment for early Universe physics, with potentially access to a large number of modes. We consider three different categories of theoretically motivated models: the sharp feature models, resonance models, and standard clock models. We study the improvements on bounds on features as a function of the total number of observed modes and identify parameter degeneracies. The detectability depends critically on the amplitude, frequency and scale-location of the features, as well as the angular and redshift resolution of the experiment. We quantify these effects by considering different fiducial models. Our forecast shows that a cosmic variance limited 21 cm experiment measuring fluctuations in the redshift range $30\leq z \leq 100$ with a 0.01-MHz bandwidth and sub-arcminute angular resolution could potentially improve bounds by several orders of magnitude for most features compared to current Planck bounds. At the same time, 21 cm tomography also opens up a unique window into features that are located on very small scales.

description: Upcoming space-based coronagraphic instruments in the next decade will perform reflected light spectroscopy and photometry of cool, directly imaged extrasolar giant planets. We are developing a new atmospheric retrieval methodology to help assess the science return and inform the instrument design for such future missions, and ultimately interpret the resulting observations. Our retrieval technique employs a geometric albedo model coupled with both a Markov chain Monte Carlo Ensemble Sampler (emcee) and a multimodal nested sampling algorithm (MultiNest) to map the posterior distribution. This combination makes the global evidence calculation more robust for any given model, and highlights possible discrepancies in the likelihood maps. As a proof-of-concept, our current atmospheric model contains 1 or 2 cloud layers, methane as a major absorber, and a H$_2$-He background gas. This 6-to-9 parameter model is appropriate for Jupiter-like planets and can be easily expanded in the future. In addition to deriving the marginal likelihood distribution and confidence intervals for the model parameters, we perform model selection to determine the significance of methane and cloud detection as a function of expected signal-to-noise in the presence of spectral noise correlations. After internal validation, the method is applied to realistic spectra of Jupiter, Saturn, and HD 99492 c, a model observing target. We find that the presence or absence of clouds and methane can be determined with high confidence, while parameter uncertainties are model-dependent and correlated. Such general methods will also be applicable to the interpretation of direct imaging spectra of cloudy terrestrial planets.
