Angiographic performance of a novel sirolimus-coated balloon in native coronary lesions: the FAtebenefratelli SIrolimus COated NATIVES prospective registry.

AIMS To evaluate the angiographic performance of a novel sirolimus-coated balloon (SCB) in de novo coronary lesions. METHODS Out of an all-comer prospective registry of patients treated with the SCB at our center from April 2016 to September 2017, we selected those treated for a de novo stenosis on a native vessel, with a scheduled angiographic control at at least 4 months after the index procedure. We performed a centralized, blinded core-lab adjudicated quantitative coronary angiography analysis. Primary endpoint was late lumen loss. Secondary endpoints were binary restenosis and target-lesion revascularization. RESULTS A total of 27 patients with native coronary arteries treated with SCB and with angiographic follow-up entered the study; seven patients were excluded because a stent was implanted at the lesion site during the index procedure. The degree of calcification (assessed with coronary angiography) was high in six patients (30%) and the average lesion length was 20.52 ± 6.88 mm. The reference vessel diameter was 2.32 ± 0.44 mm and the percentage diameter stenosis was 67 ± 12. Procedural success was obtained in all patients. After a median of 6.6 ± 2.5 months, late lumen loss was 0.09 ± 0.34 mm and the percentage diameter stenosis was 31 ± 18. We observed two cases (10%) of binary restenosis which underwent subsequent target-lesion revascularization: in one a drug-eluting stent was implanted, whereas the other patient was treated with paclitaxel-coated balloon. No myocardial infarction or death was observed during follow-up. CONCLUSION The use of a novel SCB in native coronary arteries was associated with good angiographic outcome at 6-month follow-up.
On the Point Behavior of Fourier Series and Conjugate Series

We investigate the point behavior of periodic functions and Schwartz distributions when the Fourier series and the conjugate series are both Abel summable at a point. In particular we show that if f is a bounded function and its Fourier series and conjugate series are Abel summable to values gamma and beta at the point theta(0), respectively, then the primitive of f is differentiable at theta(0), with derivative equal to gamma, the conjugate function satisfies lim(theta ->theta 0) 3/(theta-theta(0))(3) integral(theta)(theta 0) (f) over tildet (theta - t)(2) dt = beta, and the Fourier series and the conjugate series are both (C, kappa) summable at theta(0), for any kappa > 0. We show a similar result for positive measures and L-1 functions bounded from below. Since the converse of our results are valid, we therefore provide a complete characterization of simultaneous Abel summability of the Fourier and conjugate series in terms of "average point values", within the classes of positive measures and functions bounded from below. For general L-1 functions, we also give a.e. distributional interpretation of -1/2 pi p.v. integral(pi)(-pi) f(t + theta(0)) cott/2 dt as the point value of the conjugate series when viewed as a distribution. We obtain more general results of this kind for arbitrary trigonometric series with coefficients of slow growth, i.e., periodic distributions.
Accurate Compton scattering measurements of noble gases: the importance of electron correlations in heavy atoms

The Compton profiles of He, Ar and Xe atoms are measured using 121.7 keV synchrotron x-rays. Comparisons of the results with recent mean-field Dirac–Hartree–Fock calculations reveal that the degree of discrepancy between the experiment and theory increases as the atomic number increases although the profile of He is reproduced well by the calculation. This study underlines the importance of incorporating the effects of electron correlations into the relativistic calculations.
On the slow quenching of ℳ* galaxies: heavily obscured AGNs clarify the picture

We investigate the connection between X-ray and radio-loud AGNs and the physical properties of their evolved and massive host galaxies, focussing on the mass-related quenching channel followed by $\mathcal{M}^\star (\simeq 10^{10.6} M_\odot)$ galaxies in the rest-frame NUVrK colour diagram at $0.2 10^{11}M_\odot$) galaxies, ruling out their feedback as a primary driver of $\mathcal{M}^\star$ galaxy quenching, we found that (2) X-ray AGNs affected by heavy obscuration of their soft X-ray emission are mostly hosted by $\mathcal{M}^\star$ galaxies that are in the process of quenching. This is consistent with a quenching scenario that involves mergers of (gas-poor) $\mathcal{M}^\star$ galaxies $after$ the onset of the quenching process, i.e., a scenario where $\mathcal{M}^\star$ galaxy mergers are not the cause but rather an aftermath of the quenching mechanism(s). In that respect, we discuss how our results may support a picture where the slow quenching of $\mathcal{M}^\star$ galaxies happens due to halo-halo mergers along cosmic filaments.
Outlier Robust Finite Population Estimation

Abstract Outliers in sample data are a perennial problem for applied survey statisticians. Moreover, it is a problem for which traditional sample survey theory offers no real solution, beyond the sensible advice that such sample elements should not be weighted to their fullest extent in estimation. Sample outliers can be identified as of two basic types. Here we are concerned with the first type, which may conveniently be termed representative outliers. These are sample elements with values that have been correctly recorded and that cannot be assumed to be unique. That is, there is no good reason to assume there are no more similar outliers in the nonsampled part of the target population. The remaining sample outliers, which by default are termed nonrepresentative, are sample elements whose data values are incorrect or unique in some sense. Methods for dealing with these nonrepresentative outliers lie basically within the scope of survey editing and imputation theory and are, therefore, not considered in .
Hyperbolic-sine analogues of Eisenstein series, generalized Hurwitz numbers, and q-zeta functions

Abstract. We consider certain double series of Eisenstein type involving hyperbolic-sine functions. We define certain generalized Hurwitz numbers, in terms of which we evaluate those double series. Our main results can be regarded as a certain generalization of well-known results of Hurwitz, Herglotz, Katayama and so on. Our results also include recent formulas of the third-named author which are double analogues of the formulas of Cauchy, Mellin, Ramanujan, Berndt and so on, about certain Dirichlet series involving hyperbolic functions. As an application, we give some evaluation formulas for q-zeta functions at positive integers.
Variation of Supergranule Parameters with Solar Cycles: Results from Century-long Kodaikanal Digitized Ca ii K Data

The Ca ii K spectroheliograms spanning over a century (1907–2007) from Kodaikanal Solar Observatory, India, have recently been digitized and calibrated. Applying a fully automated algorithm (which includes contrast enhancement and the “Watershed method”) to these data, we have identified the supergranules and calculated the associated parameters, such as scale, circularity, and fractal dimension. We have segregated the quiet and active regions and obtained the supergranule parameters separately for these two domains. In this way, we have isolated the effect of large-scale and small-scale magnetic fields on these structures and find a significantly different behavior of the supergranule parameters over solar cycles. These differences indicate intrinsic changes in the physical mechanism behind the generation and evolution of supergranules in the presence of small-scale and large-scale magnetic fields. This also highlights the need for further studies using solar dynamo theory along with magneto-convection models.
Effects of construction history on the stress distribution under a sand pile

We report experiments on cohesionless granular piles to determine the effect of construction history on the static stress distribution. The stresses beneath the piles are monitored using a very sensitive capacitive technique. The piles are formed either by release of granular material from a relatively small output (localized source), or from a large diameter sieve (homogeneous rain). The stress profiles resulting from localized source inputs have a clear stress dip near the center of the pile while the results from an homogeneous rain show no stress dip. We also show that the stress profiles scale simply with the pile height. Experiments on wedges-shaped piles show the same effects but to a lesser degree.
Quantum aspects of self-interacting fields around cosmic strings

The authors study the quantum effect of self-interacting fields in the classical background of conical space, i.e. around a cosmic string with infinitesimal width. The renormalized value of ( phi 2) and energy-momentum tensor in the presence of cosmic strings are calculated in the self-interacting scalar field theory. The amount of condensation is also estimated in the case of the Dirac Lagrangian with the four-fermion interaction. The physical implications of the above analyses are discussed.
On effective constraints for the Riemann–Lanczos system of equations

There have been conflicting points of view concerning the Riemann–Lanczos problem in three and four dimensions. Using direct differentiation on the defining partial differential equations, Massa and Pagani (in four dimensions) and Edgar (in dimensions n⩾3) have argued that there are effective constraints so that not all Riemann tensors can have Lanczos potentials; using Cartan’s criteria of integrability of ideals of differential forms Bampi and Caviglia have argued that there are no such constraints in dimensions n⩽4, and that, in these dimensions, all Riemann tensors can have Lanczos potentials. In this article we give a simple direct derivation of a constraint equation, confirm explicitly that known exact solutions of the Riemann–Lanczos problem satisfy it, and argue that the Bampi and Caviglia conclusion must therefore be flawed. In support of this, we refer to the recent work of Dolan and Gerber on the three-dimensional problem; by a method closely related to that of Bampi and Caviglia, they have fou.
On the lifespan and the blowup mechanism of smooth solutions to a class of 2-D nonlinear wave equations with small initial data

This paper is concerned with the lifespan and the blowup mechanism for smooth solutions to the 2-D nonlinear wave equation $\p_t^2u-\ds\sum_{i=1}^2\p_i(c_i^2(u)\p_iu)$ $=0$, where $c_i(u)\in C^{\infty}(\Bbb R^n)$, $c_i(0)\neq 0$, and $(c_1'(0))^2+(c_2'(0))^2\neq 0$. This equation has an interesting physics background as it arises from the pressure-gradient model in compressible fluid dynamics and also in nonlinear variational wave equations. Under the initial condition $(u(0,x), \p_tu(0,x))=(\ve u_0(x), \ve u_1(x))$ with $u_0(x), u_1(x)\in C_0^{\infty}(\Bbb R^2)$, and $\ve>0$ is small, we will show that the classical solution $u(t,x)$ stops to be smooth at some finite time $T_{\ve}$. Moreover, blowup occurs due to the formation of a singularity of the first-order derivatives $\na_{t,x}u(t,x)$, while $u(t,x)$ itself is continuous up to the blowup time $T_{\ve}$.
The cell functional minimization scheme for the anisotropic diffusion problems on arbitrary polygonal grids

A finite volume scheme based on minimization of a certain cell functional is constructed for unstructured polygonal meshes. This new scheme has a local stencil, allows arbitrary diffusion tensors, leads to a symmetric positive definite diffusion matrix in case that edge unknowns are defined at the midpoints of edges, and is linearity-preserving, i.e. , preserves linear solutions. Under a very weak geometry condition, the stability result and discrete H 1 error estimate of the scheme is obtained through a discrete functional approach. Finally, numerical results on various mesh types (including a particular jigsaw puzzle mesh) demonstrate the good performance of the scheme and validate the theoretical analysis.
Sensitivity of the Tropospheric Circulation to Changes in the Strength of the Stratospheric Polar Vortex

Abstract The sensitivity of the wintertime tropospheric circulation to changes in the strength of the Northern Hemisphere stratospheric polar vortex is studied using one of the latest versions of the ECMWF model. Three sets of experiments were carried out: one control integration and two integrations in which the strength of the stratospheric polar vortex has been gradually reduced and increased, respectively, during the course of the integration. The strength of the polar vortex is changed by applying a forcing to the model tendencies in the stratosphere only. The forcing has been obtained using the adjoint technique. It is shown that, in the ECMWF model, changes in the strength of the polar vortex in the middle and lower stratosphere have a significant and slightly delayed (on the order of days) impact on the tropospheric circulation. The tropospheric response shows some resemblance to the North Atlantic Oscillation (NAO), though the centers of action are slightly shifted toward the east compared to tho.
Transport and Deposition of Angular Fibers in Turbulent Channel Flows

Transport and deposition of angular fibrous particles in turbulent channel flows were studied. The instantaneous fluid velocity field was generated by the direct numerical simulation (DNS) of the Navier-Stokes equation via a pseudo-spectral method. An angular fibers was assumed to consist of two elongated ellipsoids attached at their tips. For a dilute suspension of fibers, a one-way coupling assumption was used in that the flow carries the fibers, but the coupling effect of the fiber on the flow was neglected. The particle equations of motion used included the hydrodynamic forces and torques, the shear-induced lift and the gravitational forces. The hydrodynamic interactions of the high aspect ratio linkage were assumed to be negligibly small. Euler's four parameters (quaternions) were used for describing the time evolution of fiber orientations. Ensembles of fiber trajectories and orientations in turbulent channel flows were generated and statistically analyzed. The results were compared with those for spherical particles and straight fibers and their differences were discussed. Effects of fiber size, aspect ratio, fiber angle, turbulence near wall eddies, and various forces were studied. The DNS predictions were compared with experimental data for straight fibers and a proposed empirical equation model.
Low-lying meson spectrum of largeNCstrongly coupled lattice QCD

We compute the low energy mass spectrum of lattice QCD in the large $N_C$ limit. Expanding around a gauge-invariant ground state, which spontaneously breaks the discrete chiral symmetry, we derive an improved strong-coupling expansion and evaluate, for any value of $N_C$, the masses of the low-lying states in the unflavored meson spectrum. We then take the 't Hooft limit by rescaling $g^2 N_C\to g^2$; the 't Hooft limit is smooth and no arbitrary parameters are needed. We find, already at the fourth order of the strong coupling perturbation theory, a very good agreement between the results of our lattice computation and the known continuum values.
Overexpression of microRNA‐186 inhibits angiogenesis in retinoblastoma via the Hedgehog signaling pathway by targeting ATAD2

Retinoblastoma (RB) represents an aggressive malignancy in the eye during the period of infancy and childhood. We delineated the ability of microRNA‐186 (miR‐186) to influence viability, invasion, migration, angiogenesis, and apoptosis of RB via the Hedgehog signaling pathway by targeting AAA domain‐containing protein 2 (ATAD2). The microarray‐based analysis was adopted to identify differentially expressed genes (DEGs) related to RB. Subsequently, RB cells were treated with miR‐186 mimic, miR‐186 inhibitor, or si‐ATAD2. The expression of miR‐186, ATAD2, Hedgehog signaling pathway‐related genes were evaluated, and the target relationship between miR‐186 and ATAD2 was verified. Finally, cell proliferation, invasion, migration, apoptosis, and angiogenesis were assessed. ATAD2 was identified as a DEG and modulated by miR‐186. Moreover, we revealed that ATAD2 was highly expressed, whereas miR‐186 was lowly expressed, and the Hedgehog signaling pathway was activated in RB. Then, ATAD2 as a putative target of miR‐186 was validated using a luciferase assay. miR‐186 mimic or siRNA‐ATAD2 in RB cells reduced cell viability, invasion, and migration coordinating with elevated apoptosis via impairing the Hedgehog signaling pathway, where repressed angiogenesis was observed. Overexpression of miR‐186 attenuates RB via the inactivation of the Hedgehog signaling pathway by downregulating ATAD2.
Correlated charge detection for readout of a solid-state quantum computer

The single-electron transistor (SET) is a prime candidate for reading out the final state of a qubit in a solid-state quantum computer. Such a measurement requires the detection of subelectron charge motion in the presence of random charging events. We present a detection scheme where the signals from two SETs are cross-correlated to suppress unwanted artifacts due to charge noise. This technique is demonstrated by using the two SETs to detect the charge state of two coupled metal dots, thereby simulating charge transfer and readout in a two-qubit system. These measurements indicate that for comparable buried dopant semiconductor architectures, the minimum measurement time required to distinguish between the two charge states is of the order of 10 ns.
Finite set of invariants to characterize local Clifford equivalence of stabilizer states

The classification of stabilizer states under local Clifford (LC) equivalence is of particular importance in quantum error-correction and measurement-based quantum computation. Two stabilizer states are called LC equivalent if there exists a local Clifford operation which maps the first state to the second. We present a finite set of invariants which completely characterizes the LC equivalence class of any stabilizer state. Our invariants have simple descriptions within the binary framework in which stabilizer states are usually described.
BM ORIONIS, THE ECLIPSING BINARY IN THE TRAPEZIUM

Photoelectric UBV observations of BM Orionis were obtained by offsetting in a consistent manner which corrected for both nebulosity and scattered light. A complete li ht curve was obtained in V, with U and B observations made at maximum an minimum. A secondary eclipse of 0" O4 was found; rimary eclipse, shown to be an occultation, had a totali lastin nine hours. T e new ephemeris is JD 2440265.343 + 6d470525 E. So ution o the V light curve gave k = 0.29 I 0.03, rg = O.274,Lg = 0.591, audi = 83 & Thesha ekandde thk agreed very well. The V magnitudes and the B- V and U- B in ices were 93, , and - 0'! '58 for the hotter star and , , and - for the cooler star, respectively. A plot on the color-color diagram indicated that the hotter star is B2 or B3, in good agreement with spectral classifications. The cooler star is anomalous and can be considered an Al star with U-B = Withft9)') = 0.35 9)' a, from Struve and Titus and with the 9)'t:L relation applied only to the B star, the resulting dimensions are 5.4 9)'u,2.5 Ro. , Mv = 07 for the B star and 2.89)'to. , 8.5 R Mv - for the A star. The B star is thus below the observational ZAMS of Blaauw but on the theoretical ZAMS of Iben; the A star is two magnitudes overluminous for its mass. The dimensions imply that the B star is about 5 X 10 years old, seemingly older than the Trapezium (10 years) presumably because of its binary nature. With = I and m - M = 8"'2 I 0"'2 for the Trapezium, the resulting Av/ 4 6 0 8 implying that this ratio is larger than 3.0 but not as large as 5.5.
Spatially Resolved Dense Molecular Gas Excitation in the Nearby LIRG VV 114

We present high-resolution observations (0.″2–1.″5) of multiple dense gas tracers, HCN and HCO+ (J = 1–0, 3–2, and 4–3), HNC (J = 1–0), and CS (J = 7–6) lines, toward the nearby luminous infrared galaxy VV 114 with the Atacama Large Millimeter/submillimeter Array. All lines are robustly detected at the central gaseous filamentary structure, including the eastern nucleus and the overlap region, the collision interface of the progenitors. We found that there is no correlation between star formation efficiency and dense gas fraction, indicating that the amount of dense gas does not simply control star formation in VV 114. We predict the presence of more turbulent and diffuse molecular gas clouds around the overlap region compared to those at the nuclear region, assuming a turbulence-regulated star formation model. The intracloud turbulence at the overlap region might be excited by galaxy-merger-induced shocks, which also explains the enhancement of gas-phase CH3OH abundance previously found there. We also present spatially resolved spectral line energy distributions of HCN and HCO+ for the first time, and derive excitation parameters by assuming optically thin and local thermodynamic equilibrium (LTE) conditions. The LTE model revealed that warmer, HCO+-poorer molecular gas medium is dominated around the eastern nucleus, harboring an active galactic nucleus (AGN). The HCN abundance is remarkably flat (∼3.5 × 10−9) independently of the various environments within the filament of VV 114 (i.e., AGN, star formation, and shock).
ALMA deep field in SSA22: Survey design and source catalog of a 20 arcmin2 survey at 1.1 mm

To search for dust-obscured star-formation activity in the early Universe, it is essential to obtain a deep and wide submillimeter/millimeter map. The advent of the Atacama Large Millimeter/submillimeter Array (ALMA) has enabled us to obtain such maps with sufficiently high spatial resolution to be free from source confusion. We present a new 1.1 mm-wave map obtained by ALMA in the SSA22 field. The field contains a remarkable proto-cluster at z = 3.09; therefore, it is an ideal region to investigate the role of a large-scale cosmic web on dust-obscured star formation. The typical 1 sigma depth of our map is 73 mu Jy beam(-1) with a 0. '' 5 resolution. Combining the present survey with earlier, archived observations, we map an area of 20 arcmin(2) (71 comoving Mpc(2) at z = 3.09). Within the combined survey area we have detected 35 sources at a signal-to-noise ratio (S/N) > 5, with flux densities of S-1.1 mm = 0.43-5.6 mJy, equivalent to star-formation rates of greater than or similar to 100-1000 M-circle dot yr(-1) at z = 3.09, for a Chabrier initial mass function: 17 sources out of 35 are new detections. The cumulative number counts show an excess by a factor of three to five compared to blank fields. The excess suggests enhanced, dust-enshrouded star-formation activity in the proto-cluster on a 10 comoving Mpc scale, indicating accelerated galaxy evolution in this overdense region.
