On the identification of a vortex

Considerable confusion surrounds the longstanding question of what constitutes a vortex, especially in a turbulent flow. This question, frequently misunderstood as academic, has recently acquired particular significance since coherent structures (CS) in turbulent flows are now commonly regarded as vortices. An objective definition of a vortex should permit the use of vortex dynamics concepts to educe CS, to explain formation and evolutionary dynamics of CS, to explore the role of CS in turbulence phenomena, and to develop viable turbulence models and control strategies for turbulence phenomena. We propose a definition of a vortex in an incompressible flow in terms of the eigenvalues of the symmetric tensor ${\bm {\cal S}}^2 + {\bm \Omega}^2$; here ${\bm {\cal S}}$ and ${\bm \Omega}$ are respectively the symmetric and antisymmetric parts of the velocity gradient tensor ${\bm \Delta}{\bm u}$. This definition captures the pressure minimum in a plane perpendicular to the vortex axis at high Reynolds numbers, and also accurately defines vortex cores at low Reynolds numbers, unlike a pressure-minimum criterion. We compare our definition with prior schemes/definitions using exact and numerical solutions of the Euler and Navier–Stokes equations for a variety of laminar and turbulent flows. In contrast to definitions based on the positive second invariant of ${\bm \Delta}{\bm u}$ or the complex eigenvalues of ${\bm \Delta}{\bm u}$, our definition accurately identifies the vortex core in flows where the vortex geometry is intuitively clear.
Three-Dimensional Wind Field Analysis from Dual-Doppler Radar Data. Part II: Minimizing the Error due to Temporal Variation

Abstract One of the major problems in three-dimensional wind field analysis from dual (or multiple) Doppler radar data resides in the non-stationary of the observed air flow within the volume sampling time which ranges typically from 2 to 5 min. The present part II is focused on this problem. Most often, the storm moves horizontally at a speed of 5–25 m s−1.Therefore, the temporal variation for a fixed observer at ground level results from the superposition of two effects: 1) the intrinsic temporal variation (or variation seen in a frame moving with the storm) and 2) the effect of horizontal advection. The first contribution of the paper concerns the development of an algorithm for correcting for the advection effect in the case of a dual-Doppler radar observation. This algorithm, which provides a mathematically exact solution to the problem of correcting for advection, can be very easily implemented in a computer program. The second contribution deals with the errors that may arise from an accurate (or l.
Definable V-topologies, Henselianity and NIP

We initiate the study of definable [Formula: see text]-topologies and show that there is at most one such [Formula: see text]-topology on a [Formula: see text]-henselian NIP field. Equivalently, we show that if [Formula: see text] is a bi-valued NIP field with [Formula: see text] henselian (respectively, [Formula: see text]-henselian), then [Formula: see text] and [Formula: see text] are comparable (respectively, dependent). As a consequence, Shelah’s conjecture for NIP fields implies the henselianity conjecture for NIP fields. Furthermore, the latter conjecture is proved for any field admitting a henselian valuation with a dp-minimal residue field. We conclude by showing that Shelah’s conjecture is equivalent to the statement that any NIP field not contained in the algebraic closure of a finite field is [Formula: see text]-henselian.
An algebraic model for rational naive-commutative equivariant ring spectra

Equipping a non-equivariant topological E_\infty operad with the trivial G-action gives an operad in G-spaces. The algebra structure encoded by this operad in G-spectra is characterised homotopically by having no non-trivial multiplicative norms. Algebras over this operad are called naive-commutative ring G-spectra. In this paper we let G be a finite group and we show that commutative algebras in the algebraic model for rational G-spectra model the rational naive-commutative ring G-spectra.
Optical refrigeration progress: cooling below NIST cryogenic temperature of 123K

We have achieved cryogenic optical refrigeration with a record low temperature in optical refrigeration by cooling 5% wt.Yb:YLF crystal to 119K ±1K (~-154 C) at 1=1020 nm corresponding to its E4-E5 Stark manifold resonance with an estimated cooling power of 18 mW. This demonstration confirms the predicted minimum achievable temperature (MAT). Further cooling is achievable as shown by measurements of a doping study where a 10% wt. Yb:YLF crystal with reduced parasitic heating has predicted cooling below 100K (~-173K).
Advances in the growth of alkaline-Earth halide single crystals for scintillator detectors

Alkaline-earth scintillators such as strontium iodide and other alkaline-earth halides activated with divalent europium represent some of the most efficient and highest energy resolution scintillators for use as gamma-ray detectors in a wide range of applications. These applications include the areas of nuclear nonproliferation, homeland security, the detection of undeclared nuclear material, nuclear physics and materials science, medical diagnostics, space physics, high energy physics, and radiation monitoring systems for first responders, police, and fire/rescue personnel. Recent advances in the growth of large single crystals of these scintillator materials hold the promise of higher crystal yields and significantly lower detector production costs. In the present work, we describe new processing protocols that, when combined with our molten salt filtration methods, have led to advances in achieving a significant reduction of cracking effects during the growth of single crystals of SrI2:Eu2+. In particular, we have found that extended pumping on the molten crystalgrowth charge under vacuum for time periods extending up to 48 hours is generally beneficial in compensating for variations in the alkaline-earth halide purity and stoichiometry of the materials as initially supplied by commercial sources. These melt-pumping and processing techniques are now being applied to the purification of CaI2:Eu2+ and some mixed-anion europium-doped alkaline-earth halides prior to single-crystal growth by means of the vertical Bridgman technique. The results of initial studies of the effects of aliovalent doping of SrI2:Eu2+ on the scintillation characteristics of this material are also described.
A geometric approach to the synthesis of failure detection filters

A geometric formulation of Beard's failure detection filter problem is stated using the concepts of (C, A) -invariant and unobservability subspaces. The notions of output separable and mutually detectable families of subspaces introduced by Beard are also clarified. It is shown that mutual detectability is a necessary and sufficient condition for the existence of a detection filter with arbitrarily assignable spectrum. Moreover, it is shown that the failure detection falter problem has a computationally simple solution when the failure events satisfy some mild restrictions. Finally, the complete duality between a generalization of Beard's detection filter problem and the restricted control decoupling problem is illustrated.
Homogenization of obstacle problems in Orlicz–Sobolev spaces

We study the homogenization of obstacle problems in Orlicz-Sobolev spaces for a wide class of monotone operators (possibly degenerate or singular) of the $p(\cdot)$-Laplacian type. Our approach is based on the Lewy-Stampacchia inequalities, which then give access to a compactness argument. We also prove the convergence of the coincidence sets under non-degeneracy conditions.
Transitive factorisations in the symmetric group, and combinatorial aspects of singularity theory

We consider the determination of the number c k ( α ) of ordered factorisations of an arbitrary permutation on n symbols, with cycle distribution α, into k -cycles such that the factorisations have minimal length and such that the group generated by the factors acts transitively on the n symbols. The case k = 2 corresponds to the celebrated result of Hurwitz on the number of topologically distinct holomorphic functions on the 2-sphere that preserve a given number of elementary branch point singularities. In this case the monodromy group is the full symmetric group. For k = 3 , the monodromy group is the alternating group, and this is another case that, in principle, is of considerable interest. We conjecture an explicit form, for arbitrary k, for the generating series for c k ( α ) , and prove that it holds for factorisations of permutations with one, two and three cycles ( α is a partition with at most three parts). The generating series is naturally expressed in terms of the symmetric functions dual to the those introduced by Macdonald for the “top” connection coeﬃcients in the class algebra of the symmetric group. Our approach is to determine a diﬀerential equation for the generating series from a combinatorial analysis of the creation and annihilation of cycles in products under the minimality condition.
B → ρ transition form factors and the ρ-meson transverse leading-twist distribution amplitude

The QCD light-cone sum rules (LCSR) provide an effective way for dealing with heavy-to-light transition form factors (TFFs), in which the non-perturbative dynamics are parameterized into the light-meson’s light-cone distribution amplitudes (LCDAs). By taking the chiral correlator as the starting point, we derive new LCSRs for TFFs up to twist-4 accuracy. In those LCSRs, the twist-2 transverse LCDA provides dominant contribution, while the twist-3 and twist-4 contributions are δ2-suppressed (). Thus, they provide good platforms for testing behavior. For the purpose, we suggest a WH-model for , in which a single parameter dominantly controls its longitudinal distribution. When setting , varies from the single-peak behavior to the double-humped behavior. We present a detailed comparison of the LCSR estimation for TFFs with those predicted by pQCD and lattice QCD calculations. The TFFs become smaller with the increment of and a larger is not allowed by lattice QCD predictions. By using the extrapolated TFFs, we further predict the Cabibbo–Kobayashi–Maskawa (CKM)-matrix element with the help of two semi-leptonic decays. The predicted increases with the increment of , i.e. we have for and for . If treating the BABAR prediction on as a criteria, we observe that should be within the region of [−0.20, +0.10], which indicates that the ρ-meson LCDA prefers a single-peak behavior rather than a double-humped behavior.
Deeply Virtual Compton Scattering off Helium-4

The Generalized Parton Distributions (GPDs) are rich structure functions that contain information on quark/anti-quark correlations, and on correlation between longitudinal momentum and the transverse spatial position of partons. These GPDs are accessible via hard exclusive reactions such as Deeply Virtual Compton Scattering (DVCS), i.e. the leptoproduction of a real photon where the photon is emitted by the target hadron. Nuclear DVCS opens a new avenue to explore the nature of medium modifications at the partonic level. In this work, we present the first exclusive measurement of the DVCS process off helium-4 with a longitudinally polarized electron beam of 6 GeV using the CLAS detector in the experimental Hall-B at Jefferson Lab, USA. The helium-4 is of particular interest since the number of GPDs is reduced to one, because of its spin zero. The aim of this study is to understand the nuclear medium modifications of parton distributions. In our experiment, the CLAS detector was upgraded with a Radial Time Projection Chamber (RTPC) to detect the low-energy recoil nuclei, and an Inner Calorimeter (IC) to detect the forward going photons. The details of the structure, calibration and working principle of the RTPC will be presented. Then, the measurement of the beam-spin asymmetries in the DVCS channel will be presented.
Complete Devil's Staircase, Fractal Dimension, and Universality of Mode- Locking Structure in the Circle Map

It is shown numerically that the stability intervals for limit cycles of the circle map form a complete devil's staircase at the onset of chaos. The complementary set to the stability intervals is a Cantor set of fractal dimension $D=0.87$. This exponent is found to be universal for a large class of functions.
The social functions of mimicry on the consequences and qualifiers of facial imitation

This thesis deals with the social functions of mimicry. Mimicry was defined broadly as 'doing what others are doing'. This 'doing' can be verbal or nonverbal behaviors and expressions, like words, accents, speech rates, postures, gestures, and facial expressions. Part I of this thesis was aimed to provide insights on the social functions of mimicry by thoroughly inquiring and relating social benefits of mimicry to each other. In Part II, this investigation on the social functions of mimicry was proceeded by examining the limitations of mimicry-effects. Overall, the current thesis shows that mimicry has social benefits for mimickers and mimickees; empathy and understanding is facilitated, which creates a special bond between people. When those consequences of mimicry appear not to be functional in specific situations, the effects of mimicry are reduced. This implies that mimicry can be a tool to regulate people's social lives, which cannot be forced. However, people catch others' emotions due to mimicry regardless its functions. Implying that people have an innate tendency to feel into other people's emotions via mimicry, which can only be disrupted when losing one's facial expressions. The findings have implications for understanding why people nonconsciously and automatically mimic. It seems that mimicry facilitates interactions and creates bonds between people. But more importantly, mimicry facilitates empathy and understanding for one another, which is the basis of positive and lasting relationships
Effect of AlN addition on the photoluminescence and phosphorescence properties of SrAl2O4 : Eu2+,Dy3+ phosphors

Abstract. The effect of AlN addition on the phase structures and luminescence properties of SrAl2O4:Eu2+,Dy3+ phosphor has been discussed. SrAl2+xO4Nx:0.02Eu2+,0.03Dy3+ (x=0 to 0.3) phosphors have been synthesized by a solid-state reaction. X-ray powder diffraction shows that the phase structures of as-prepared SrAl2+xO4Nx:0.02Eu2+,0.03Dy3+ remain invariable with the SrAl2O4 phase when the content of AlN is below 0.3. With the addition of AlN, photoluminescence intensities of SrAl2+xO4Nx:0.02Eu2+,0.03Dy3+ phosphors decrease with increasing x; however, the afterglow phosphorescence intensities obviously increased. The mechanism of the enhanced phosphorescence properties was also discussed.
The effect of the external pressure on the internal conditions inside the discharge tube

The model for quasi-steady-state operation of the discharge tube by A. Loeb and Z. Kaplan (see IEEE Trans. Magn., vol.25, p.342-6, Jan. 1989) is extended to include the dependence of the axial pressure, density, and velocity profiles inside the discharge tube on the external conditions. An interesting analogy between the discharge tube and the subsonic converging nozzle is demonstrated. The sensitivity of internal tube parameters to the external pressure is determined. The axial profiles are calculated and plotted, and three qualitatively different regimes are identified. Although the present analysis is semiqualitative and cannot replace a full 1-D time-dependent simulation, its results might be helpful as guidelines in the design of discharge tubes for electrothermal accelerators. >
Periodic long-time behaviour for an approximate model of nematic polymers

We study the long-time behaviour of a nonlinear Fokker-Planck equation, which models the evolution of rigid polymers in a given flow, after a closure approximation. The aim of this work is twofold: first, we propose a microscopic derivation of the classical Doi closure, at the level of the kinetic equation ; second, under specific assumptions on the parameters and the initial condition, we prove convergence of the solution to the Fokker-Planck equation to a particular periodic solution in the long-time limit.
The comparison of different coherence function and application

Considering seismic spatial effect, different bridge support has different stimulation, and the action usually be decided by spatial seismic effect. So far, a variety of coherence functions have been modeled and advised. Through the comparison, QWW model is appropriate to create the external stimulation wave. At last, a usual procedure for seismic wave generation is given considering the coherence effect.
The coarse Baum--Connes conjecture and groupoids II

Given a (not necessarily discrete) proper metric space $M$ with bounded geometry, we define a groupoid $G(M)$. We show that the coarse Baum--Connes conjecture with coefficients, which states that the assembly map with coefficients for G(M) is an isomorphism, is hereditary by taking closed subspaces.
General solutions of the Wess-Zumino consistency condition for the Weyl anomalies

The general solutions of the Wess-Zumino consistency condition for the Weyl anomalies are derived in a purely algebraic manner. The solutions are obtained, in arbitrary dimensions, by explicitly computing the cohomology of the corresponding Becchi-Rouet-Stora-Tyutin differential in the space of integrated local functions at ghost number unity.
Hom-Lie Color Algebra Structures

The aim of this article is to introduce the notion of Hom-Lie color algebras. This class of algebras is a natural generalization of the Hom-Lie algebras as well as a special case of the quasi-hom-Lie algebras. In the article, homomorphism relations between Hom-Lie color algebras are defined and studied. We present a way to obtain Hom-Lie color algebras from the classical Lie color algebras along with algebra endomorphisms and offer some applications. Also, we introduce a multiplier σ on the abelian group Γ and provide constructions of new Hom-Lie color algebras from old ones by the σ-twists. Finally, we explore some general classes of Hom-Lie color admissible algebras and describe all these classes via G–Hom-associative color algebras, where G is a subgroup of the symmetric group S 3.
A simple accurate solution to minority electron injection in the p-type heavily doped emitter region of silicon devices

In the p-type quasi-neutral and heavily doped emitter region of silicon devices at room temperature, with the aid of our accurate empirical models for the apparent band-gap narrowing and minority-electron lifetime, a simple accurate theory of minority-electron (emitter) saturation current density JEO, and effective minority-electron transit time, which are expressed as functions of the surface acceptor density Ns, the electron surface recombination velocity S, and the emitter width W, is derived and discussed. It is found that, under transparent emitter region condition, our theoretical values of JEO(Ns) for S = ∞ and 0.19 μm ≦ W ≦ 0.25 μm are in good agreement with the corresponding ones measured by Cuevas et al., with a precision of the order of 22%. Dans la region d'emitteur tres dope et quasi-neutre de type p des dispositifs a silicium, a la temperature ambiante, a l'aide de nos expressions empiriques et precises de reduction de la bande interdite et de duree de vie des electrons minoritaires, une theorie precise mais simple de densite de courant-saturation de l'emitteur JEO, et de temps de transit des electrons, exprimes en fonction de la concentration maximale des accepteurs Ns, la vitesse de recombinaison electronique a la surface S, et la largeur de l'emitteur W, est obtenue et discutee. Dans la condition de transparence de la region d'emitteur, pour S = ∞ and 0,19 μm ≦ W ≦ 0,25 μm, nos valeurs theoriques de JEO(Ns) sont en bon accord avec celles mesurees par Cuevas et al., avec une precision de l'ordre de 22%.
Oscillator strengths of A, B, and C excitons in ZnO films

We examine how the short-range part of the electron--hole exchange interaction influences the strain-induced variations of the oscillator strength in ZnO films. Our model enables us to account for the surprisingly small oscillator strength of the A exciton in $E\ensuremath{\perp}c$ polarization without having to invoke any inverted valence-band scheme. We then conclude that the valence-band physics is very similar in both ZnO and GaN.
A Quasi‐Sliding Mode Observer‐based Controller for PMSM Drives

In this paper a quasi‐sliding mode control for a permanent magnet synchronous motor (PMSM) is proposed where a cascade control scheme based on a properly designed state observer provides accurate speed tracking performance. The ultimate boundedness of both the observation error and the speed tracking error is proven. The controller performance has been validated using hardware in the loop (HIL) tests on a simulator based on the model of a commercial PMSM drive. Tests show that the proposed observer‐based controller produces good speed trajectory tracking performance and it is robust in the presence of disturbances affecting the system.
