description: System of differential equations describing the initial stage of the capture of oscillatory systems into the parametric autoresonance is considered. Of special interest are solutions whose amplitude increases without bound with time. The possibility of capture the system into the autoresonance is related with the stability of such solutions. We study the stability of autoresonant solutions with respect to persistent perturbations of white noise type, and we show that under certain conditions on the intensity of the noise, the capture into parametric autoresonance is preserved with probability tending to one.

description: CONTEXT: Evidence-based strategies to prevent progression of dysglycemia in newly diagnosed type 2 diabetes are needed.

OBJECTIVE: To undertake a secondary analysis of the Early Diabetes Intervention Program (EDIP) in order to understand the features that were protective against worsening glycemia.

DESIGN: EDIP was a randomized, placebo-controlled trial.

SETTING: Two university diabetes centers.

PATIENTS: A total of 219 overweight individuals with fasting glucose < 7.8 mmol/L and 2-hour oral glucose tolerance test (OGTT) glucose > 11.1 mmol/L.

INTERVENTIONS: Acarbose versus placebo, on a background of dietary recommendations, with quarterly visits to assess glycemia and intervention adherence for up to 5 years.

MAIN OUTCOME MEASURES: Progression of fasting glucose ≥ 7.8 mmol/L on two consecutive quarterly visits. Cox proportional hazards modeling and ANOVA were performed to evaluate determinants of progression.

RESULTS: Progression-free status was associated with reductions in weight, fasting glucose, 2-hour OGTT glucose, and increases in the high-density lipoprotein/triglyceride ratio. The reduction in fasting glucose was the only effect that remained significantly associated with progression-free status in multivariable Cox modeling. The reduction in fasting glucose was in turn primarily associated with reductions in weight and in 2-hour OGTT glucose. Acarbose treatment did not explain these changes.

CONCLUSIONS: In early diabetes, reductions in glucose, driven by reductions in weight, can delay progressive metabolic worsening. These observations underscore the importance of lifestyle management including weight loss as a tool to mitigate worsening of glycemia in newly diagnosed diabetes.
Small Winding-Number Expansion: Vortex Solutions at Critical Coupling

Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study an axially symmetric solution of a vortex in the Abelian-Higgs model at critical coupling in detail. Here we propose a new idea for a perturbative expansion of a solution, where the winding number of a vortex is naturally extended to be a real number and the solution is expanded with respect to it around its origin. We test this idea on three typical constants contained in the solution and confirm that this expansion works well with the help of the Padé approximation. For instance, we analytically reproduce the value of the scalar charge of the vortex with an error of $O(10^{-6})$. This expansion is also powerful even for large winding numbers.

description: Quantum entanglement provides a novel way to test short distance physics in the non-relativistic regime. We will provide a protocol to {\it potentially} test new physics by bringing two charged massive particle interferometers adjacent to each other. Being charged, the two superpositions will be entangled via electromagnetic interactions mediated by the photons, including the Coulomb and the Casimir-Polder potential. We will bring a method of {\it entanglement based tomography} to seek time evolution of very small entanglement phases to probe new physical effects mediated by {\it hitherto unknown macroscopic force} which might be responsible for entangling the two charged superpositions modelled by the Yukawa type potential. We will be able to constrain the Yukawa couplings $α\geq 10^{-35}$ for $r\geq 10^{-6}$m for new physics occurring in the electromagnetic sector, and in the gravitational potential $α_g \geq 10^{-8}$ for $r \geq 10^{-6}$m. Furthermore, our protocol can also constrain the axion like particle mass and coupling, which is complimentary to the existing experimental bounds.

description: An analysis of absorption profiles of the $λ$6614 diffuse interstellar band recorded along the lines-of-sight towards HD 179406 (20 Aql) and HD 147889 is described. The difference in band shape is attributed to the degree of internal excitation of the carrier, which is principally due to vibrational hot bands although an electronic component may also be present. The results are discussed with respect to other models of diffuse band spectral line shape.

description: Numerically exact simulations of quantum reaction dynamics, including non-adiabatic effects in excited electronic states, are essential to gain fundamental insights into ultrafast chemical reactivity and rigorous interpretations of molecular spectroscopy. Here, we introduce the tensor-train split-operator KSL (TT-SOKSL) method for quantum simulations in tensor-train (TT)/matrix product state (MPS) representations. TT-SOKSL propagates the quantum state as a tensor train using the Trotter expansion of the time-evolution operator, as in the tensor-train split-operator Fourier transform (TT-SOFT) method. However, the exponential operators of the Trotter expansion are applied using a rank adaptive TT-KSL scheme instead of using the scaling and squaring approach as in TT-SOFT. We demonstrate the accuracy and efficiency of TT-SOKSL as applied to simulations of the photoisomerization of the retinal chromophore in rhodopsin, including non-adiabatic dynamics at a conical intersection of potential energy surfaces. The quantum evolution is described in full dimensionality by a time-dependent wavepacket evolving according to a two-state 25-dimensional model Hamiltonian. We find that TT-SOKSL converges faster than TT-SOFT with respect to the maximally allowed memory requirement of the tensor-train representation and better preserves the norm of the time-evolving state. When compared to the corresponding simulations based on the TT-KSL method, TT-SOKSL has the advantage of avoiding the need of constructing the matrix product state Laplacian by exploiting the linear scaling of multidimensional tensor train Fourier transforms.

description: We obtain a complete time expansion of the pull-back operator generated by a real analytic flow of real analytic automorphisms acting on analytic tensor sections of a manifold. Our expansion is given in terms of multiple Lie derivatives. Motivated by this expansion, we provide a rather simple and explicit estimate for higher order covariant derivatives of multiple Lie derivatives acting on smooth endomorphism sections of the tangent bundle of a manifold. We assume the covariant derivative to be torsion free. The estimate is given in terms of Dyck polynomials. The proof uses a new result on the combinatorics of rooted labeled ordered forests and Dyck polynomials.

description: Cross-sectional mri-studies comparing psychiatric patients with healthy individuals have shown that patients show brain morphometric as well as functional changes. However, it is unclear whether these are pathological factors or whether these neurobiological changes are simply a risk factor for mental disorders, a consequence of therapy, only occur in certain subgroups. Therefore, the influence of a broad spectrum of different risk factors for mental disorders on brain morphometry as well as function was investigated in the present study: polygenic risk scores for psychiatric disorders, temporal perspective, shortened prenatal development as well as an extremely high risk for the development of psychosis. It can be shown that these risk factors significantly influence brain structural parameters as well as brain function. Some of these changes also correlated with behavioural changes such as poorer cognitive performance. These behavioural correlates could be valuable diagnostic or prognostic markers and could also be important research targets for the development of new therapeutic approaches.

description: CONTEXT: Diet modification is a mainstay of diabetes management. US Hispanics/Latinos are disproportionately affected by diabetes, but few studies have examined dietary intake among US Hispanics/Latinos with diabetes, and little is known regarding the influence of diabetes awareness on dietary intake.

OBJECTIVE: We evaluated macronutrient intake and its associations with diabetes awareness and glycemic control among US Hispanics/Latinos with diabetes.

PARTICIPANTS: This analysis included 3310 diabetic adults aged 18–74 years from the Hispanic Community Health Study/Study of Latinos (2008–2011).

MAIN OUTCOME MEASURES: Diabetes was defined as diagnosed (based on medical history or antihyperglycemic medication use) or undiagnosed diabetes (based on fasting glucose ≥ 126 mg/dL, glycated hemoglobin [HbA1c] ≥ 6.5%, or 2 h glucose ≥ 200 mg/dL in the absence of a physician diagnosis). Dietary intake was assessed using two 24-hour recalls.

RESULTS: Among Hispanic/Latino adults with diabetes, 21.2%, 55.7%, and 71.2% met the American Diabetes Association recommendations for fiber (≥14 g per 1000 kcal), saturated fat (<10% of total energy), and cholesterol intake (<300 mg), respectively. Compared with those with undiagnosed diabetes, people with diagnosed diabetes consumed less carbohydrate (50.3 vs 52.4% of total energy; P = .017), total sugar (19.1 vs 21.5% of total energy; P = .002), added sugar (9.8 vs 12.1% of total energy; P < .001), and more total fat (30.7 vs 29.3% of total energy; P = .048) and monounsaturated fat (11.5 vs 10.7% of total energy; P = .021). Association between diabetes awareness and low total and added sugar intake was observed in individuals of Mexican and Puerto Rican background but not in other groups (P for interaction < .05). Among people with diagnosed diabetes, those with HbA1c of 7% or greater consumed more total fat, saturated fat, and cholesterol than those with HbA1c less than 7% (all P < .05).

CONCLUSIONS: Among US Hispanics/Latinos with diabetes, fiber intake is low, and diabetes awareness is associated with reduced carbohydrate and sugar intake and increased monounsaturated fat intake. Sugar intake may require special attention in certain Hispanic/Latino background groups.

description: An excitable chemical medium --- Belousov-Zhabotinsky (BZ) reaction --- is proven to be a fruitful substrate for prototyping unconventional computing devices. These include image processors, logical circuits, and robot controllers. We study a BZ potential for characterising a geometry of street networks on a fragment of Tehran street map. The city was chosen because it is one of the most populated cities in the World with nearly uncontrollable urban growth. In numerical experiments with Oregonator model of BZ reaction, we demonstrate that excitability of the medium allows acts as a selector between omnidirectional waves and soliton-like localised excitations. We uncover a phase-transition like dynamics, controlled by the excitability, of coverage of the street network by excitation wave-fronts. In the cluster analysis, we show how the network geometry, when it meets propagation of BZ wave-front, relates to the traffic flow of Tehran

description: The structural, electronic and optical properties of nearly ferromagnetic compound HfZn2 have been studied using ab-initio technique. We have carried out the plane-wave pseudopotential approach within the framework of the first-principles density functional theory (DFT) implemented within the CASTEP code. The calculated structural parameters show a good agreement with the experimental results. In our work we have used GGA-PBE to calculate the electronic properties and it is found that the results exhibit similar band structure qualitatively with the results calculated using LDA. The electronic band structure reveals metallic conductivity and the major contribution comes from Hf-5d states. Our results for structural and electronic properties are compared with the experimental and other theoretical results wherever these are available.

description: We simulate the excited states of the Lipkin model using the recently proposed Quantum Equation of Motion (qEOM) method. The qEOM generalizes the EOM on classical computers and gives access to collective excitations based on quasi-boson operators $\hat{O}^\dagger_n(α)$ of increasing configuration complexity $α$. We show, in particular, that the accuracy strongly depends on the fermion to qubit encoding. Standard encoding leads to large errors, but the use of symmetries and the Gray code reduces the quantum resources and improves significantly the results on current noisy quantum devices. With this encoding scheme, we use IBM quantum machines to compute the energy spectrum for a system of $N=2, 3$ and $4$ particles and compare the accuracy against the exact solution. We found that the results of the approach with $α= 2$, an analog of the second random phase approximation (SRPA), are, in principle, more accurate than with $α= 1$, which corresponds to the random phase approximation (RPA), but the SRPA is more amenable to noise for large coupling strengths. Thus, the proposed scheme shows potential for achieving higher spectroscopic accuracy by implementations with higher configuration complexity, if a proper error mitigation method is applied.

description: The size and mass of two circum-galactic medium (CGM) clouds in the halo (impact parameter = 65 kpc) of a nearby late-type galaxy, MGC-01-04-005 ($cz = 1865$ km/s), are investigated using a close triplet of QSO sight lines (the "LBQS Triplet"; Crighton et al. 2010). Far ultraviolet spectra obtained with the Cosmic Origins Spectrograph (COS) aboard the Hubble Space Telescope (HST) find two velocity components in Lyman $α$ at $\sim1830$ and 1900 km/s in two of these sight lines, requiring minimum transverse cloud sizes of $\geq10$ kpc. A plausible, but not conclusive, detection of CIV 1548 Å absorption at the higher velocity in the third sight line suggests an even larger lower limit of $\geq23$ kpc for that cloud. Using various combinations of constraints, including photo-ionization modeling for one absorber, lower limits on masses of these two clouds of $\geq10^6$ M_Sun are obtained. Ground-based imaging and long-slit spectroscopy of MCG -01-04-005 obtained at the Apache Point Observatory (APO) 3.5m telescope find it to be a relatively normal late-type galaxy with a current star formation rate (SFR) of $\sim0.01$ M_Sun per year. Galaxy Evolution Explorer (GALEX) photometry finds an SFR only a few times higher over the last $10^8$ yrs. We conclude that the CGM clouds probed by these spectra are typical in being at impact parameters of 0.4-0.5 R_vir from a rather typical, non-starbursting late-type galaxy so that these size and mass results should be generic for this class. Therefore, at least some CGM clouds are exceptionally large and massive.

description: We study mass deformations of certain three dimensional $\mathcal{N}=4$ Superconformal Field Theories (SCFTs) that have come to be called $T^ρ[G]$ theories. These are associated to tame defects of the six dimensional $(0,2)$ SCFT $X[\mathfrak{j}]$ for $\mathfrak{j}=A,D,E$. We describe these deformations using a refined version of the theory of sheets, a subject of interest in Geometric Representation Theory. In mathematical terms, we parameterize local mass-like deformations of the tamely ramified Hitchin integrable system and identify the subset of the deformations that do admit an interpretation as a mass deformation for the theories under consideration. We point out the existence of non-trivial Rigid SCFTs among these theories. We classify the Rigid theories within this set of SCFTs and give a description of their Higgs and Coulomb branches. We then study the implications for the endpoints of RG flows triggered by mass deformations in these 3d $\mathcal{N}=4$ theories. Finally, we discuss connections with the recently proposed idea of Symplectic Duality and describe some conjectures about its action.

description: Context: Endometriosis results in aberrant gene expression in the eutopic endometrium (EuE) and subsequent progesterone resistance. MicroRNA (miR) microarray data in a baboon model of endometriosis showed an increased expression of miR-29c.

Objectives: To explore the role of miR-29c in progesterone resistance in a subset of women with endometriosis.

Design: MiR-29c expression was analyzed in the endometrium of baboons and women with or without endometriosis. The role in progesterone resistance and decidualization was analyzed by transfecting human uterine fibroblast cells with miR-29c.

Patients: Subjects diagnosed with deep infiltrative endometriosis (DIE) by transvaginal ultrasound with bowel preparation underwent surgical excision of endometriosis. Eutopic secretory endometrium was collected pre- and postoperatively. Women with normal EuE and without DIE served as controls.

Results: Quantitative reverse transcription polymerase chain reaction demonstrated that miR-29c expression increased, while the transcript levels of its target, FK506-binding protein 4 (FKBP4), decreased in the EuE of baboons following the induction of endometriosis. FKBP4 messenger RNA and decidual markers were statistically significantly decreased in decidualized human uterine fibroblast cells transfected with a miR-29c mimic compared with controls. Human data corroborated our baboon data and demonstrated higher expression of miR-29c in endometriosis EuE compared with normal EuE. MiR-29c was significantly decreased in endometriosis EuE postoperatively compared with preoperative tissues, and FKBP4 showed an inverse trend following radical laparoscopic resection surgery.

Conclusions: We demonstrate that miR-29c expression is increased in EuE of baboons and women with endometriosis, which might contribute to a compromised progesterone response by diminishing the levels of FKBP4. Resection of DIE is likely to reverse the progesterone resistance associated with endometriosis in women.

description: We consider a cosmological model consisting of two scalar fields defined in the hyperbolic plane known as hyperbolic inflation. For the background space, we consider a homogeneous and isotropic spacetime with nonzero curvature. We study the asymptotic behaviour of solutions and we search for attractors in the expanding regime. We prove that two hyperbolic inflationary stages are stable solutions that can solve the flatness problem and describe acceleration for both open and closed models, and additionally we obtain a Milne-like attractor solution for the open model. We also investigate the contracting branch obtaining mirror solutions with the opposite dynamical behaviours.

description: Dynamical systems describe the changes in processes that arise naturally from their underlying physical principles, such as the laws of motion or the conservation of mass, energy or momentum. These models facilitate a causal explanation for the drivers and impediments of the processes. But do they describe the behaviour of the observed data? And how can we quantify the models' parameters that cannot be measured directly? This paper addresses these two questions by providing a methodology for estimating the solution; and the parameters of linear dynamical systems from incomplete and noisy observations of the processes. The proposed procedure builds on the parameter cascading approach, where a linear combination of basis functions approximates the implicitly defined solution of the dynamical system. The systems' parameters are then estimated so that this approximating solution adheres to the data. By taking advantage of the linearity of the system, we have simplified the parameter cascading estimation procedure, and by developing a new iterative scheme, we achieve fast and stable computation. We illustrate our approach by obtaining a linear differential equation that represents real data from biomechanics. Comparing our approach with popular methods for estimating the parameters of linear dynamical systems, namely, the non-linear least-squares approach, simulated annealing, parameter cascading and smooth functional tempering reveals a considerable reduction in computation and an improved bias and sampling variance.

description: This paper describes a new multilevel procedure that can solve the discrete Navier-Stokes system arising from finite volume discretizations on composite grids, which may consist of more than one level. SIMPLE is used and tested as the smoother, but the multilevel procedure is such that it does not exclude the use of other smoothers. Local refinement is guided by a criterion based on an estimate of the truncation error. The numerical experiments presented test not only the behaviour of the multilevel algebraic solver, but also the efficiency of local refinement based on this particular criterion.

description: Active materials are capable of converting free energy into mechanical work to produce autonomous motion, and exhibit striking collective dynamics that biology relies on for essential functions. Controlling those dynamics and transport in synthetic systems has been particularly challenging. Here, we introduce the concept of spatially structured activity as a means to control and manipulate transport in active nematic liquid crystals consisting of actin filaments and light-sensitive myosin motors. Simulations and experiments are used to demonstrate that topological defects can be generated at will, and then constrained to move along specified trajectories, by inducing local stresses in an otherwise passive material. These results provide a foundation for design of autonomous and reconfigurable microfluidic systems where transport is controlled by modulating activity with light.

description: We study probability density functions that are log-concave. Despite the space of all such densities being infinite-dimensional, the maximum likelihood estimate is the exponential of a piecewise linear function determined by finitely many quantities, namely the function values, or heights, at the data points. We explore in what sense exact solutions to this problem are possible. First, we show that the heights given by the maximum likelihood estimate are generically transcendental. For a cell in one dimension, the maximum likelihood estimator is expressed in closed form using the generalized W-Lambert function. Even more, we show that finding the log-concave maximum likelihood estimate is equivalent to solving a collection of polynomial-exponential systems of a special form. Even in the case of two equations, very little is known about solutions to these systems. As an alternative, we use Smale's alpha-theory to refine approximate numerical solutions and to certify solutions to log-concave density estimation.

description: Due to iron's low toxicity and abundance on Earth, chiral inexpensive metallic iron catalysts have gained great attention. There are still no examples of the direct use of simple and readily available chiral iron catalysts to catalyse the activation of C-H bonds to enantioselectively form C-N bonds. This thesis is based on the enantioselective catalytic amination of challenging secondary and tertiary C-H bonds via chiral N4 iron catalysts. At the same time, the enantioselective amination produces a series of unnatural α-amino acids. A novel approach for synthesizing α-amino acids is disclosed. In the first two sections, a series of chiral N4 iron catalysts were synthesized and successfully applied to asymmetric secondary C-H bonds amination reactions. Our method employs abundant and easily accessible carboxylic acids as starting materials, which are connected to a nitrogenation reagent, followed by a highly regio- and enantioselective iron-catalyzed C(sp3)-H amination. This straightforward method displays a broad scope, providing rapid access to optically active α-amino acids with aryl, allyl, and alkyl side chains, and also permits stereocontrolled late-stage amination of carboxylic acid-containing drugs and natural products. In the third section, A straightforward two-step synthesis of non-racemic α,α-disubstituted α-amino acids by an enantioconvergent 1,3-migratory nitrene C(sp3)-H insertion is reported. Readily available racemic α-branched carboxylic acids are DCC/EDCI-coupled to provide racemic azanyl esters which undergo a rearrangement into non-racemic N-Troc-protected α,α-disubstituted α-amino acids catalyzed by an easy to store and robust chiral iron catalyst. α,α-Disubstituted α-amino acids with one aryl group in α-position are provided in yields of up to 99% and with up to 88% ee. Selected examples demonstrate that recrystallization can improve the enantiomeric excess to 99% ee.

description: We propose a measurement of the top Yukawa coupling at a 100 TeV hadron collider, based on boosted Higgs and top decays. We find that the top Yukawa coupling can be measured to 1%, with excellent handles for reducing systematic and theoretical uncertainties, both from side bands and from $t\bar{t}H/t\bar{t}Z$ ratios.

description: Equilibrium thermodynamic laws are typically applied to horizons in general relativity without stating the conditions that bring them into equilibrium. We fill this gap by applying a new thermodynamic interpretation to a generalized Raychaudhuri equation for a worldsheet orthogonal to a closed spacelike 2-surface, the "screen", which encompasses a system of arbitrary size in nonequilibrium with its surroundings in general. In the case of spherical symmetry this enables us to identify quasilocal thermodynamic potentials directly related to standard quasilocal energy definitions. Quasilocal thermodynamic equilibrium is defined by minimizing the mean extrinsic curvature of the screen. Moreover, without any direct reference to surface gravity, we find that the system comes into quasilocal thermodynamic equilibrium when the screen is located at a generalized apparent horizon. Examples of the Schwarzschild, Friedmann-Lemaître and Lemaître-Tolman geometries are investigated and compared. Conditions for the quasilocal thermodynamic and hydrodynamic equilibrium states to coincide are also discussed, and a quasilocal virial relation is suggested as a potential application of this approach.

description: Context: US Hispanic/Latino youth are disproportionally affected by the obesity and diabetes.

Objective: We examined associations of adiposity measures with insulin resistance (IR) and hyperglycemia and the influences of sex and pubertal development on these associations.

Design, Setting, and Participants: We performed a cross-sectional analysis of 1223 8- to 16-year-old Hispanic/Latino youth from a community-based study in the United States (SOL Youth).

Main Outcome Measures: We measured IR (≥75th percentile of sex-specific Homeostatic Model Assessment of Insulin Resistance) and hyperglycemia (fasting glucose ≥100 mg/dL or hemoglobin a1c ≥5.7%).

Results: In boys, body mass index (BMI) showed the strongest association with IR [prevalence ratio (PR), 2.10; 95% confidence interval (CI), 1.87 to 2.36 per standard deviation], which was not statistically different compared with body fat percentage (%BF) (PR, 2.03; 95% CI, 1.81 to 2.29) and waist circumference (WC) (PR, 1.89; 95% CI, 1.67 to 2.13) but was significantly stronger compared with fat mass index (FMI) (PR, 1.79; 95% CI, 1.63 to 1.96), waist-to-hip ratio (WHR) (PR, 1.32; 95% CI, 1.21 to 1.44), and waist-to-height ratio (WHtR) (PR, 1.76; 95% CI, 1.54 to 2.01) (P for difference, <0.05). In girls, %BF (PR, 2.73; 95% CI, 2.34 to 3.20) showed a significantly stronger association with IR compared with BMI (PR, 1.48; 95% CI, 1.29 to 1.70), FMI (PR, 1.71; 95% CI, 1.49 to 1.95), WC (PR, 1.96; 95% CI, 1.70 to 2.27), WHR (PR, 1.95; 95% CI, 1.70 to 2.23), and WHtR (PR, 1.79; 95% CI, 1.53 to 2.09) (P for difference, <0.003). Associations between adiposity measures and IR were generally stronger among children in puberty versus those who had completed puberty, with significant interactions for WC and WHtR in boys and for BMI in girls (P for interaction, <0.01). Adiposity measures were modestly associated with hyperglycemia (PR, 1.14 to 1.25), with no interactions with sex or pubertal status.

Conclusions: Sex and puberty may influence associations between adiposity measures and IR in US Hispanic/Latino youth. Multiple adiposity measures are needed to better assess IR risk between boys and girls according to pubertal status.
