Abstract:

The generation of high-order harmonics in a semi-infinite cell by femtosecond laser pulses is a common practice for reliable coherent and low divergence XUV source beams for applications. Despite the relative simplicity of the experimental method, several phenomena coexist that affect the generated spectral and divergence characteristics of the high harmonic XUV frequency comb. The ionisation degree of the medium and the consequent plasma formation length imposes a spatiotemporal evolution of the fundamental EM field and XUV absorption. Varying the laser pulse chirp and the focusing conditions, as well as the gas density, we measured intense harmonic spectral and divergence variations attributed mainly to self-phase modulations of the laser EM field in the partially ionised medium. Additionally, low-divergence high harmonics are observed for certain laser chirp values attributed to the strong phase matching of only the short electron quantum path. Thus, a tunable, low divergent, and coherent XUV source can be realised for spatiotemporal imaging applications in the nanoscale.

Abstract:

Rousseau and Marx represent two paradigmatic variants of a radical opposition to the world. Without a doubt, there are significant moments of convergence between these thinkers, for instance in terms of division of labour, or in respect to the self-commandment. However, it is our contention that despite certain currents in literature, the tendencies of divergence are stronger than convergence, therefore, we argue that these thinkers signify two different variants of radical thought. We base these differences in a reading of Rousseau that focuses on collective authenticity, justice, self-presentation of people and protest against envy. Marx cannot be read from the perspective of the intensified crisis of non-authenticity, in fact, his critique of political economy generates a reflexive field (overcoming of the wage labour, etc.), which is deeply divergent compared to Rousseau.

Abstract:

Using Leibbrandt's general prescription for regularizing (n · q)−1 poles in momentum intergrals in axial-type non-covariant gauges we show that the difference between two linearly divergent integrals which arise in such gauges yield a surface term which is logarithmically divergent. The form of divergence of this term is shown to be independent of the choice of non-covariant gauge. We show that such a term modifies the expression for the one-loop Yang–Mills self-energy evaluated using a cutoff scheme of adding to it a divergent part.

Abstract:

The pointxfor which the limitlimr→0⁡(log⁡μBx,r/log⁡r)does not exist is called divergence point. Recently, multifractal structure of the divergence points of self-similar measures has been investigated by many authors. This paper is devoted to the study of some Moran measures with the support on the homogeneous Moran fractals associated with the sequences of which the frequency of the letter exists; the Moran measures associated with this kind of structure are neither Gibbs nor self-similar and than complex. Such measures possess singular features because of the existence of so-called divergence points. By the box-counting principle, we analyze multifractal structure of the divergence points of some homogeneous Moran measures and show that the Hausdorff dimension of the set of divergence points is the same as the dimension of the whole Moran set.

Abstract:

Various mathematical models are created for exploring complex self-organizing systems. In geosystems, the deterministic nature of processes is due to their stochastic properties. In such systems, regular deterministic processes are formed by numerous random interelement interactions that occur at the micro level. In many cases, it is not possible to define correctly the deterministic law of evolution of the observable system or its part because of the large number of unpredictable and unknown factors that influence it. However, at the micro level, statistical distributions of system elements are available for observation, which allows to predict its behavior and evaluate the factors influencing the system. The most universal methods for modeling systems with stochastic properties are based on the fundamental concepts of statistical mechanics — the Gibbs-Shannon and Renyi information entropies. The article studies the entropy methods for calculating quantitative estimations of the states of spatially distributed geosystems and their divergences in the process of self-organization: alpha-divergence, Kullback divergence, variability of the spectrum of Renyi dimensions. The features of the above systems with multifractal structures according to hyperspectral measurements are observed. The examples illustrate the use of entropy models in numerical experiments with real data obtained from a natural gas field. Verification of the entropy methods for determining the boundaries of hydrocarbon deposits based on the hyperspectral data of emission of a homogeneous vegetation cover was carried out.

Abstract:

Two-dimensional magnetosonic beams directed along a line forming a constant angle θ with the equilibrium straight magnetic field are considered. Perturbations in a plasma are described by the system of ideal magnetohydrodynamic equations. The dynamics of perturbations in a beam are different in the cases of fast and slow modes, and it is determined by θ and equilibrium parameters of a plasma. In particular, a beam divergence may be unusual in the case of parallel propagation ( θ = 0). Diffraction is more pronounced in the case of parallel propagation as compared to a flow without magnetic field, and less manifested in the case of perpendicular propagation. The beams propagating oblique to the magnetic field do not reveal diffraction. The dynamics of perturbations in a beam are analytically described in the cases of weak and strong nonlinearity compared to diffraction. Small magnitude perturbations at the axis of a beam in unusual cases propagate slower than that in the plane wave. Involving of thermal conduction leads to the coupling equations describing thermal self-action of a beam, which behaves differently in the ordinary and unusual cases. Self-focusing may occur in the presence of a magnetic field instead of conventional defocusing in gases.

Abstract:

Supervised and unsupervised vector quantization methods for classification and clustering traditionally use dissimilarities, frequently taken as Euclidean distances. In this article, we investigate the applicability of divergences instead, focusing on online learning. We deduce the mathematical fundamentals for its utilization in gradient-based online vector quantization algorithms. It bears on the generalized derivatives of the divergences known as Fréchet derivatives in functional analysis, which reduces in finite-dimensional problems to partial derivatives in a natural way. We demonstrate the application of this methodology for widely applied supervised and unsupervised online vector quantization schemes, including self-organizing maps, neural gas, and learning vector quantization. Additionally, principles for hyperparameter optimization and relevance learning for parameterized divergences in the case of supervised vector quantization are given to achieve improved classification accuracy.

Abstract:

Abstract Analysis of nucleotide sequences that regulate the expression of self-incompatibility in flowering plants affords a direct means of examining classical hypotheses for the origin and evolution of this major feature of mating systems. Departing from the classical view of monophyly of all forms of self-incompatibility, the current paradigm for the origin of self-incompatibility postulates multiple episodes of recruitment and modification of preexisting genes. In Brassica, the S locus, which regulates sporophytic self-incompatibility, shows homology to a multigene family present both in self-compatible congeners and in groups for which this form of self-incompatibility is atypical. A phylogenetic analysis of S-allele sequences together with homologous sequences that do not cosegregate with self-incompatibility permits dating the change of function that marked the origin of self-incompatibility. A generalized least-squares method is introduced that provides closed-form expressions for estimates and standard errors for function-specific divergence rates and times of divergence among sequences. This analysis suggests that the age of the sporophytic self-incompatibility system expressed in Brassica exceeds species divergence within the genus by four- to fivefold. The extraordinarily high levels of sequence diversity exhibited by S alleles appears to reflect their ancient derivation, with the alternative hypothesis of hypermutability rejected by the analysis.

CNN templates for image processing and pattern formation are derived from neural field equations, advection equations and reaction–diffusion equations by discretizing spatial integrals and derivatives. Many useful CNN templates are derived by this approach. Furthermore, self-organization is investigated from the viewpoint of divergence of vector fields.

Abstract:

In a single-component material, a chemical potential gradient or a wind force drives self-diffusion. If the self-diffusion flux has a divergence, the material deforms. We formulate a continuum theory to be consistent with this kinematic constraint. When the diffusion flux is divergence-free, the theory decouples into Stokes’s theory for creep and Herring’s theory for self-diffusion. A length emerges from the coupled theory to characterize the relative rate of self-diffusion and creep. For a flow in a film driven by a stress gradient, creep dominates in thick films, and self-diffusion dominates in thin films. Depending on the film thickness, either stress-driven creep or stress-driven diffusion prevails to counterbalance electromigration. The transition occurs when the film thickness is comparable to the characteristic length of the material.

Abstract:

We review gauge invariant [Formula: see text] supersymmetric massive U(1) gauge theory coupled to matter and Stuckelberg superfields. We focus on the leading order self-energy and vertex correction to the matter field in the massless limit of both the U(1) vector superfield and the Stuckelberg superfield. We explicitly verify that the theory is infrared divergence free in the massless limit. Hence the Stuckelberg mechanism appears to be the efficient route to handle infrared divergences seen in supersymmetric quantum electrodynamics. Since these additional particles have very small masses they can serve as dark matter candidates through “Ultralight particles” mechanism.

Abstract:

AbstractThis article reports on a study of ethnic variation in the phonetics of Montreal English. The speech of 93 native speakers of Montreal English from three ethnic groups, British-Irish, Italian and Jewish, was recorded and subjected to acoustic analysis. Several statistically significant differences among the ethnic groups were identified. The present paper undertakes an apparent-time analysis of these differences, to see whether they are getting smaller over time, as might be expected under the assumption that post-immigrant generations gradually assimilate to the linguistic and cultural patterns of their adopted homelands. While Jewish Montrealers show some signs of convergence with the British-origin standard, Italians — especially young Italian men—appear to be diverging from that model. It is suggested that the unusual persistence and even intensification of ethno-phonetic variation in English-speaking Montreal reflects both the residential and social self-segregation of its ethnic communities and the local dominance of French.

Abstract:

In both religion & philosophy, the concept of self is of tremendous significance. It has always been an idea of contemplation for mankind as man has always discovered himself uncertain about the true value of his self. Self is a spiritual entity that contains the whole cosmos in itself & has dominion over the physical part of the body. Its power is fathomless & moves freely around the whole universe. Allama Iqbal & Walt Whitman are associated with different religious & cultural backgrounds, but despite this divergence, spiritual, ideological & poetical convergence can be seen in their works. The most striking similarity that can be spotted in their poetry, is their treatment of self. Both use self as a symbol of spirituality & mysticism. Iqbal’s Secret of Self & Whitman’s Song of Myself presents a distinct composition of religious, cultural, political & spiritual changes, their nations were going through. This research paper seeks to examine the poetry of Iqbal & Whitman to highlight the convergence as well as divergence in their beliefs on self.

Abstract:

AbstractKhintchine's theorem is a classical result from metric number theory which relates the Lebesgue measure of certain limsup sets with the convergence/divergence of naturally occurring volume sums. In this paper we ask whether an analogous result holds for iterated function systems (IFS's). We say that an IFS is approximation regular if we observe Khintchine type behaviour, i.e., if the size of certain limsup sets defined using the IFS is determined by the convergence/divergence of naturally occurring sums. We prove that an IFS is approximation regular if it consists of conformal mappings and satisfies the open set condition. The divergence condition we introduce incorporates the inhomogeneity present within the IFS. We demonstrate via an example that such an approach is essential. We also formulate an analogue of the Duffin–Schaeffer conjecture and show that it holds for a set of full Hausdorff dimension.Combining our results with the mass transference principle of Beresnevich and Velani [4], we prove a general result that implies the existence of exceptional points within the attractor of our IFS. These points are exceptional in the sense that they are “very well approximated”. As a corollary of this result, we obtain a general solution to a problem of Mahler, and prove that there are badly approximable numbers that are very well approximated by quadratic irrationals.The ideas put forward in this paper are introduced in the general setting of iterated function systems that may contain overlaps. We believe that by viewing iterated function systems from the perspective of metric number theory, one can gain a greater insight into the extent to which they overlap. The results of this paper should be interpreted as a first step in this investigation.

Abstract:

We focus on the early evolution of energy E and enstrophy Z when the dissipation grows in significance from negligible to important. By considering a sequence of viscous shell model solutions we find that both energy and dissipation are continuous functions of time in the inviscid limit. Inviscidly, Z takes only a finite time t* to diverge, where t* depends on initial conditions. For viscous solutions, Z peaks long after t*, but the inflection point for Z(t) provides an excellent approximation to t*. Near t*, all of our high Reynolds number solutions obey the formula ναdZ/dt = F(νβZ). Neither the function F nor the constants α and β depend on initial conditions. We use F to obtain the inviscid limit. The energy spectrum remains concave down on double logarithmic scales until t*. At t*, the spectrum becomes algebraic at high wavenumbers, i.e. E(k, t*) ∼ C0kα. Crucially, the spectral slope σ is steeper than −5/3. Thus, we conclude that the inviscid singularity at t* is not associated with the establishment of a semi-infinite Kolmogorov range. For viscous solutions, the −5/3 range builds gradually after t* starting from high wavenumbers, and Z peaks when the inertial range reaches the integral scale. Thus, the formation of the inertial range is a viscous process in our shell model.

Abstract:

The mathematical and physical properties of the Lamb vector divergence are explored. Toward this aim, the instantaneous and mean dynamics of the Lamb vector divergence are examined in several analytic and turbulent flow examples relative to its capacity to identify and characterize spatially localized motions having a distinct capacity to effect a time rate of change of momentum. In this context, the transport equation for the Lamb vector divergence is developed and shown to accurately describe the dynamical mechanisms by which adjacent high- and low-momentum fluid parcels interact to effect a time rate of change of momentum and generate forces such as drag. From this, a transport-equation-based framework is developed that captures the self-sustaining spatiotemporal interactions between coherent motions, e.g. ejections and sweeps in turbulent wall flows, as predicted by the binary source–sink distribution of the Lamb vector divergence. New insight into coherent motion development and evolution is found through the analysis of the Lamb vector divergence.

Abstract:

AbstractThe aim of this paper was to explore potential divergence and convergence in relation to health care professionals’ and patients’ acceptability of the use of telehealth within palliative care provision through the lens of Self-Determination Theory. The research utilized a deductive qualitative approach utilizing semi-structured interviews to explore divergence and convergence between health care professionals’ preconceptions of the use of telehealth in palliative care and the lived experiences of patients accessing support in this manner. Semi-structured interviews were conducted with both professionals and patients to explore whether the barriers and benefits of telehealth perceived by professionals corresponded to the patient’s lived experience of utilizing the technology in their palliative care. Interviews were analyzed using a deductive thematic analysis. Professionals and patients identified that the use of telehealth could satisfy the need for autonomy, however this manifested in different ways. Greater divergence was apparent between patient and professional perceptions about how telehealth could satisfy the need for relatedness and competence needs. The findings of this paper highlight how professionals preconceived concerns about the use of telehealth in relation to providing supportive palliative care may not be realized when exploring the experiences of patients accessing services through this medium. This paper highlights the important role of psychological need satisfaction when considering acceptability of telehealth, and motivation to engage in the implementation of technologically driven health services.

Abstract:

(1) Objectives: A divergence in self- and preceptor-evaluations of clinical skills has been noted during Advanced Pharmacy Practice Experiences (APPEs). The goal of this study was to determine the domains of overestimation of clinical skills by students during their APPE rotations. (2) Methods: Preceptor-assigned grades for APPE rotations from 2017–2022 were analyzed to identify instances of letter grade B or lower. The self- and preceptor-evaluations of APPE rotation were compared to determine the domains of divergence in evaluation between students and preceptors. (3) Results: Between 2017 and 2022, 305 student APPE rotations were graded as B or lower (~14%) by the preceptors. A statistically significant difference was noted between self- and preceptor-assigned letter grades across all practice settings including ambulatory patient care, community pharmacy, general medicine patient care, hospital/health system pharmacy, and special population patient care APPE rotations. In addition, examining the self- and preceptor evaluation rubric for these rotations revealed a statistically significant overestimation of clinical skills by students in all 9 domains of APPE evaluation. Finally, the divergence in the rating of clinical skills between student- and preceptor evaluation was found to be highest in the domains of planning and follow-up of patient care, disease knowledge, and communication with patients. (4) Conclusions: Students who fail to exhibit exemplary practice readiness during APPEs tend to overestimate their clinical skills in all domains of APPE evaluation. The results from our study support the need for additional avenues to assist in the identification of deficits in student learning before APPEs to increase their self-awareness (metacognition).

Abstract:

Vertical-cavity surface-emitting lasers (VCSELs) yield single-longitudinal-mode operation, low-divergence circular output beam, and low threshold current. This paper gives an overview on theoretical, self-consistent modelling of physical phenomena occurring in a VCSEL. The model has been experimentally confirmed. We present versatile numerical methods for nitride, arsenide, and phosphide VCSELs emitting light at wavelengths varying from violet to near infrared. We also discuss different designs with respect to optical confinement: gain guidance using tunnel junctions and index guidance using oxide confinement or photonic crystal and we focus on the problem of single-transverse-mode operation.

Abstract:

ABSTRACT The sexual development and virulence of the fungal pathogen Cryptococcus neoformans is controlled by a bipolar mating system determined by a single locus that exists in two alleles, α and a. The α and a mating-type alleles from two divergent varieties were cloned and sequenced. The C. neoformans mating-type locus is unique, spans >100 kb, and contains more than 20 genes. MAT-encoded products include homologs of regulators of sexual development in other fungi, pheromone and pheromone receptors, divergent components of a MAP kinase cascade, and other proteins with no obvious function in mating. The α and a alleles of the mating-type locus have extensively rearranged during evolution and strain divergence but are stable during genetic crosses and in the population. The C. neoformans mating-type locus is strikingly different from the other known fungal mating-type loci, sharing features with the self-incompatibility systems and sex chromosomes of algae, plants, and animals. Our study establishes a new paradigm for mating-type loci in fungi with implications for the evolution of cell identity and self/nonself recognition.

Abstract:

AbstractPropagation of an intense laser pulse in plasma with a periodically modulated density is considered using envelope equations. The laser induces modifications of the plasma refractive indexviarelativistic and ponderomotive nonlinearities. In the region of high plasma density, the self focusing effect of nonlinearity suppresses the diffraction divergence, and the laser converges. As the beam enters into the low density region, the diffraction tends to diverge it offsetting the convergence due to the curvature it has acquired. For a given set of plasma parameters, there is a critical power of the laser above which it propagates in a periodically focused manner. Below this power the laser undergoes overall divergence. At substantially higher powers, the laser beam continues to converge until the saturation effect of nonlinearity suppresses the self focusing and diffraction predominates. The effect of density ripple is to cause overall increase in the self focusing length. The minimum spot size decreases with the wave number of the ripple.

Abstract:

"When I feel like crying it’s political is a performance created through devised techniques, combining director-driven dramaturgy with content generated by the actresses-performers, in a process shifting the role of the director into one of a curator. Centered on self-representation, the work proposes a frame for empowerment while approaching sensible themes, such as the hierarchy of power in theatrical contexts (vocational schools and professional theatres) and the objectification of female performers. This paper contextualizes the concept and artistic process of the work, while proposing a work model based on care and owning differences. Keywords: self-representation, performative theatre, agency, feminism, divergence, empowerment, pedagogy of care."

Abstract:

I argue that Europe's political fragmentation interacted with her political innovations—self-governing cities and national parliaments—to facilitate “economic liberty,” which in turn unleashed faster and more inter-connected urban growth. Examining urban growth over the period 600–1800 ce throughout Eurasia, I show that inter-city growth correlations were positive and significant only in Western Europe after 1200 ce. Within Western Europe, I show that growth correlations were greatest in the most fragmented and parliamentary areas, individual cities became significantly more tied to urban growth when their realms became parliamentary, and spillover effects (due to competition between rulers) were significant.

Abstract:

Stueckelberg mechanism introduces a scalar field, known as Stueckelberg field, so that gauge symmetry is preserved in the massive Abelian gauge theory. In this work, we show that the role of the Stueckelberg field is similar to the Kulish and Faddeev coherent state approach to handle infrared (IR) divergences. We expect that the light-front quantum electrodynamics (LFQED) with Stueckelberg field must be IR finite in the massless limit of the gauge boson. We have explicitly shown the cancellation of IR divergences in the relevant diagrams contributing to self-energy and vertex correction at leading order.

Abstract:

AbstractA paraxial ray formalism is developed to study the evolution of an on axis intensity spike on a Gaussian laser beam in a plasma dominated by relativistic and ponderomotive non-linearities. Ion motion is taken to be frozen. A single beam width parameter characterizes the evolution of the spike. The spike introduces two competing influences: diffraction divergence and self-convergence. The former grows with the reduction in spot size of the spike, while the latter depends on the gradient in non-linear permittivity. Parameter δ = (ωpr00/c) a00/(3.5 r00/r01) characterizes the relative importance of the two, where r01 and r00 are the spike and main beam radii, ωp is the plasma frequency, and a00 is the normalized laser amplitude. For δ > 1, the intensity ripple causes faster self-focusing of the beam; higher the ripple amplitude stronger the focusing. In the opposite limit, diffraction divergence increases more rapidly, slowing down the self-focusing of the beam. As the beam intensity rises due to self-focusing, it causes stronger generation of the third harmonic.
