description: The experimental observation of the self$-$excited dust acoustic waves (DAWs) and its propagation characteristics in the absence and presence of a floating cylindrical object are investigated. The experiments are carried out in a direct current (DC) glow discharge dusty plasma in the background of argon gas. Dust particles are found levitated at the interface of plasma and cathode sheath region. The DAWs are spontaneously excited in the dust medium and found to propagate in the direction of ion drift (along the gravity) above a threshold discharge current at lower pressure. The excitation of such low frequency wave is a result of the ion--dust streaming instability in the dust cloud. The characteristics of the propagating dust acoustic wave get modified in presence of a floating cylindrical object of radius larger than the dust Debye length. Instead of propagating in the vertical direction, the DAWs are found to propagate obliquely in presence of the floating object (kept either vertically or horizontally). In addition, horizontally aligned floating object gives rise to form a wave structure in the cone shaped dust cloud in the sheath region. The change in the propagation characteristics of DAWs are explained on the basis of modified potential (or electric field) distribution, which is a consequence of coupling of sheaths formed around the cylindrical object and the cathode.

description: Various diaryl/hetaryl representatives of penta-1,4-dien-3-one series attract the attention of synthetic chemists during several decades owing to the possibility of their consequent chemical modification resulted in obtaining compounds of potential interest to materials science. In addition to their synthetic importance, title diarylideneacetones can be applied directly as medical drugs, such as antioxidants and anti-inflammatory agents. In this communication, we report the synthesis of a series of new asymmetric thiazole cycle containing diarylideneacetones, which further demonstrated high regioselectivity in their reaction with hydrazine. To clarify this feature, quantum-chemical modeling of the cyclization process was conducted.
Convolutional neural network search for long-duration transient gravitational waves from glitching pulsars

description: Machine learning can be a powerful tool to discover new signal types in astronomical data. We here apply it to search for long-duration transient gravitational waves triggered by pulsar glitches, which could yield physical insight into the mostly unknown depths of the pulsar. Current methods to search for such signals rely on matched filtering and a brute-force grid search over possible signal durations, which is sensitive but can become very computationally expensive. We develop a method to search for post-glitch signals on combining matched filtering with convolutional neural networks, which reaches similar sensitivities to the standard method at false-alarm probabilities relevant for practical searches, while being significantly faster. We specialize to the Vela glitch during the LIGO-Virgo O2 run, and set upper limits on the gravitational-wave strain amplitude from the data of the two LIGO detectors for both constant-amplitude and exponentially decaying signals.

Street dance culture
Xpress VIBE H.O.M.E

description: While street dance has been a hot topic of discussion for almost a decade now, it could be assumed there would also be a concerted effort to grow healthy community practices alongside its climb in popularity. As an active member of the dance community for the last twenty years, there have been efforts to center change, yet it leaves much to be desired in light of belonging. There are quarrels, beef, and separations of dance tribes within the community due to a specific reason; these communities are built outside a strong sense of belonging. My thesis project examines the current state of street dance culture from my perspective and how community facilitators can become aware of communal needs by addressing individuals through the lens of belonging. This paper investigates the process of building my performance piece Xpress VIBE H.O.M.E. Xpress VIBE H.O.M.E examines ways to reimage what culture building in street dance communities can look like based on several hypotheses tested in the rehearsal and performance process of X.V.H. In the spirit of street dance culture, this paper intentionally breaks conventional academic writing forms, switches from active voice to passive voice, and leans into ethnographic experiences. My approach is the essence of street culture, to take what is learned, remix it, and make it into your thang.

description: We study numerically the effect of mode mixing and direct dipole-dipole interactions between gain molecules on spasing in a small composite nanoparticles with a metallic core and a dye-doped dielectric shell. By combining Maxwell-Bloch equations with Green's function formalism, we calculate lasing frequency and threshold population inversion for various gain densities in the shell. We find that gain coupling to nonresonant plasmon modes has a negligible effect on spasing threshold. In contrast, the direct dipole-dipole coupling, by causing random shifts of gain molecules' excitation frequencies, hinders reaching the spasing threshold in small systems. We identify a region of parameter space in which spasing can occur considering these effects.

description: Platón fue el primero en sostener que la educación debe estar al servicio del Estado. Esto lo llevo a establecer las bases de una educación institucionalizada cuyo objetivo sería reproducir las bases de la organización política deseada. Desde Platón la educación deja de ser una actividad informal (como lo era con Sócrates) para convertirse enuna actividad formal a cargo del Estado. Para el fundador de la academia la educación es ante todo un hecho político. Esta relación entre educación y política es fundamental para entender la construcción de su estado ideal mediante la base de un sistema educativo basado en la enseñanza de la filosofía. La toma de partido del filósofo ateniense por la filosofía radica en el descubrimiento platónico de la importancia de la educación filosófica para el buen funcionamiento del estado.

description: We propose a hetero-homodyne receiver for quantum illumination (QI) target detection. Unlike prior QI receivers, it uses a cascaded positive operator-valued measurement (POVM) that does not require a quantum interaction between QI's returned radiation and its stored idler. When used without sequential detection its performance matches the 3 dB quantum advantage over optimum classical illumination (CI) that Guha and Erkmen's [Phys. Rev. A 80, 052310 (2009)] phase-conjugate and parametric amplifier receivers enjoy. When used in a sequential detection QI protocol, the hetero-homodyne receiver offers a 9 dB quantum advantage over a conventional CI radar, and a 3 dB advantage over a CI radar with sequential detection. Our work is a significant step forward toward a practical quantum radar for the microwave region, and, more generally, emphasizes the potential offered by cascaded POVMs for quantum radar.

description: Asteroid families are groups of minor bodies produced by high-velocity collisions. After the initial dispersions of the parent bodies fragments, their orbits evolve because of several gravitational and non-gravitational effects,such as diffusion in mean-motion resonances, Yarkovsky and YORP effects, close encounters of collisions, etc. The subsequent dynamical evolution of asteroid family members may cause some of the original fragments to travel beyond the conventional limits of the asteroid family. Eventually, the whole family will dynamically disperse and no longer be recognizable. A natural question that may arise concerns the timescales for dispersion of large families. In particular, what is the oldest still recognizable family in the main belt? Are there any families that may date from the late stages of the Late Heavy Bombardment and that could provide clues on our understanding of the primitive Solar System? In this work, we investigate the dynamical stability of seven of the allegedly oldest families in the asteroid main belt. Our results show that none of the seven studied families has a nominally mean estimated age older than 2.7 Gyr, assuming standard values for the parameters describing the strength of the Yarkovsky force. Most "paleo-families" that formed between 2.7 and 3.8 Gyr would be characterized by a very shallow size-frequency distribution, and could be recognizable only if located in a dynamically less active region (such as that of the Koronis family). V-type asteroids in the central main belt could be compatible with a formation from a paleo-Eunomia family.

This pattern disappears when individual returns are averaged; it is also absent in stock price indices, which points to explanations based on firm-specific drivers of re- turns.

description: Characteristic Modes Analysis (CMA) is a widely used method with recent progress in multi-antenna systems. We employ this method to characterize the mutual coupling phenomenon between two SKALA4.1 antennas, the low-frequency array elements of the future radiotelescope Square Kilometer Array (SKA-Low). The CMA accuracy is first validated at the lowest frequency range of interest with respect to a standard Method of Moments (MoM) solution by decomposing the single antenna into its characteristic modes. We then examine critical frequencies of a two-antenna system in modal decomposition, and characterize those responsible for the radiated electric field spurious spectral features owing to the mutual coupling. We connect these modes to first-order coupling of single antenna CMA modes, by using the eigenvalue data of both single- and two- antenna simulations.

Compound 6a indicated a higher activity against Gram-negative bacteria and compound 7d toward Gram-positive bacteria. Antifungal validation of the compounds revealed 7b as sensible against Aspergillus niger, Aspergillus oryzae, Candida albicans, and Penicillium chrysogenum at all concentrations. Compound 6b showed prominent cytotoxic activity with IC50 (µM) values of 0.8 ± 0.61, 1.0 ± 0.3, 1.2 ± 0.7, and 0.90 ± 0.71 against MCF-7, A-549, HeLa, and Panc-1 cancer cell lines, respectively. Compounds 6c and 10c showed significant antioxidant activity at all concentrations with ED50 values (3.39 ± 0.3 and 4.27 ± 0.5 μM, respectively). Further, docking was performed at the 1SA5 active site to anticipate their conceivable binding mode by compound 6b.

The products were obtained via two different strategies providing both exellent yields. The major advantages of this process are the short reaction time, and high productivity as well as being eco-friendly. Moreover, the obtained derivatives were assessed against different bacterial strains. Three derivatives were found to be highly effective against both studied bacterial strains.

The convenient work-up procedure, mild reaction conditions, high yields, and practically short reaction times were the specific merits of the synthetic method. In addition, the designed ionic liquid was recycled efficiently and reused four times without further decrease in the catalytic ability.

description: The title polyaromatic chalcone compound (PyMQ-chalcone) was sequentially synthesized via a three steps synthetic procedure and well characterized. Structural illumination was achieved by 1D and 2D NMR techniques, FTIR, LCMS/MS, and SEM. Photophysical investigations showed that the emission capacity remarkably increased by aggregation although target compound exhibited lower emission at solution state in common organic solvents. Furthermore, addition of some metal cations (such as Al3+ and Cr3+) slightly enhanced the emission in acetonitrile/water media in metal sensing studies. Lastly, density-functional theory studies were carried out by ORCA 4.2.0 software ((B3LYP; def2-TZVP basis set) to determine some electronic parameters such as HOMO–LUMO energy, total energy, dipol moment, and bond lengths, etc.

description: Dermal fibrosis and Parkinson's disease are two chronic syndromes affecting a large population leading to systematic morbidity. The mechanisms of these diseases are well debated, and many medicines are in the market for managing them. Recently, istradefylline was approved by the FDA as a medicine for the management of aforesaid disorders. But the detailed structure and reactivity profile of this compound was not reported. We use molecular modeling using density functional theory (DFT) and time-dependent density functional theory (TD-DFT) methods using B3LYP/CAM-B3LYP/aug-cc-pVDZ level to study the structure, reactivity and other physicochemical properties of this compound. Conformational analysis over two dihedral angles was discussed. The compound was found to be an ideal candidate for being used as an NLO material. Molar refractivity was found to be 13.19 times greater than urea and 2.61 times greater than p-nitro acetanilide. TD-DFT indicated that the compound shows excellent light-harvesting efficiency of 94.21 in the near UV region of 337.23 nm. We also report several wavefunction-based properties such as molecular electrostatic potential, localized orbital locator, average local ionization energy, local information entropy and electron localized function. Using MESP, LIE, LOL, etc., information entropy studies showed that the molecule is stable with low uncertainty electrons in spatial distribution. These studies are useful for future experimental studies involving istradefylline and will assist in the design and prediction of the activity of new derivatives from this compound.

description: The ground state of the Dirac one-electron atom, placed in a weak, static electric field of definite $2^{L}$-polarity, is studied within the framework of the first-order perturbation theory. The Sturmian expansion of the generalized Dirac-Coulomb Green function [R. Szmytkowski, J. Phys. B 30 (1997) 825, erratum: 30 (1997) 2747] is used to derive closed-form analytical expressions for various far-field and near-nucleus static electric multipole susceptibilities of the atom. The far-field multipole susceptibilities --- the polarizabilities $α_{L}$, electric-to-magnetic cross-susceptibilities $α_{\mathrm{E}L\to\mathrm{M}(L\mp1)}$ and electric-to-toroidal-magnetic cross-susceptibilities $α_{\mathrm{E}L\to\mathrm{T}L}$ --- are found to be expressible in terms of one or two non-terminating generalized hypergeometric functions ${}_{3}F_{2}$ with the unit argument. Counterpart formulas for the near-nucleus multipole susceptibilities --- the electric nuclear shielding constants $σ_{\mathrm{E}L\to\mathrm{E}L}$, near-nucleus electric-to-magnetic cross-susceptibilities $σ_{\mathrm{E}L\to\mathrm{M}(L\mp1)}$ and near-nucleus electric-to-toroidal-magnetic cross-susceptibilities $σ_{\mathrm{E}L\to\mathrm{T}L}$ --- involve terminating ${}_{3}F_{2}(1)$ series and for each $L$ may be rewritten in terms of elementary functions. Exact numerical values of the far-field dipole, quadrupole, octupole and hexadecapole susceptibilities are provided for selected hydrogenic ions. Analytical quasi-relativistic approximations, valid to the second order in $αZ$, where $α$ is the fine-structure constant and $Z$ is the nuclear charge number, are derived for all types of the far-field and near-nucleus susceptibilities considered in the paper.

Simultaneous Measurement of Two Quantum Observables: Compatibility, Broadcasting, and In-between

description: One of the central features of quantum theory is that there are pairs of quantum observables that cannot be measured simultaneously. This incompatibility of quantum observables is a necessary ingredient in several quantum phenomena, such as measurement uncertainty relations, violation of Bell inequalities and steering. Two quantum observables that admit a simultaneous measurement are, in this respect, classical. A finer classification of classicality can be made by formulating four symmetric relations on the set of observables that are stronger than compatibility; they are broadcastability, one-side broadcastability, mutual nondisturbance and nondisturbance. It is proven that the five relations form a hierarchy, and their differences in terms of the required devices needed in a simultaneous measurement is explained. All the four relations stronger than compatibility are completely characterized in the case of qubit observables.

description: A new series of 1-(6-amino-3,5-dicyano-4-(substituted)pyridin-2-yl)-4-methylthiosemicarbazide derivatives 4(a–i) was achieved by the reaction of malononitrile and 4-methyl-3-thiosemicarbazide with various aldehydes. All the newly designed compounds were structurally established by various analytical methods (IR, 1H, 13C NMR, and HRMS). Further, all the entitled derivatives were evaluated for their potential antioxidant activity by DPPH radical method in which standard, ascorbic acid, was used for comparison and results revealed that the derivatives, 4a and 4i exhibited the highest antioxidant effect.

description: We present a general review of the bifurcation sequences of periodic orbits in general position of a family of resonant Hamiltonian normal forms with nearly equal unperturbed frequencies, invariant under $Z_2 \times Z_2$ symmetry. The rich structure of these classical systems is investigated with geometric methods and the relation with the singularity theory approach is also highlighted. The geometric approach is the most straightforward way to obtain a general picture of the phase-space dynamics of the family as is defined by a complete subset in the space of control parameters complying with the symmetry constraint. It is shown how to find an energy-momentum map describing the phase space structure of each member of the family, a catastrophe map that captures its global features and formal expressions for action-angle variables. Several examples, mainly taken from astrodynamics, are used as applications.

Intra-system uniformity: a natural outcome of dynamical sculpting

description: There is evidence that exoplanet systems display intra-system uniformity in mass, radius, and orbital spacing (like ``peas in a pod'') when compared with the system-to-system variations of planetary systems. This has been interpreted as the outcome of the early stages of planet formation, indicative of a picture in which planets form at characteristic mass scales with uniform separations. In this paper, we argue instead that intra-system uniformity in planet sizes and orbital spacings likely arose from the dynamical sculpting of initially-overly-packed planetary systems (in other words, the giant impact phase). With a suite of $N$-body simulations, we demonstrate that systems with random initial masses and compact planet spacings naturally develop intra-system uniformity, in quantitative agreement with observations, due to collisions between planets. Our results suggest that the pre-giant impact planet mass distribution is fairly wide and provide evidence for the prevalence of dynamical sculpting in shaping the observed population of exoplanets.

ISADORA DUNCAN: MOTHER OF MODERN DANCE
Creators: name: Azamatova, Diyora
Publisher: name: Zenodo

description: Isadora Duncan, often referred to as the "Mother of Modern Dance," is a pivotal figure in the history of dance. This article examines Duncan's life, artistic philosophy, and revolutionary approach to movement that laid the foundation for modern dance. Through a detailed exploration of her early influences, major works, and enduring legacy, this study argues that Duncan's contributions were not merely technical innovations but a profound reimagining of dance as a vehicle for personal and spiritual expression. Duncan's influence extends beyond her immediate successors and continues to resonate in contemporary dance practices. This article examines the life, philosophy, and artistic contributions of Isadora Duncan, widely recognized as the "Mother of Modern Dance." It explores how Duncan’s rejection of classical ballet and her innovative approach to movement laid the groundwork for modern dance. Through an analysis of her artistic philosophy, key performances, and enduring legacy, this article argues that Duncan's pioneering spirit not only redefined dance but also established a new paradigm that continues to influence contemporary dance practices.

description: Learning skills by imitation is a promising concept for the intuitive teaching of robots. A common way to learn such skills is to learn a parametric model by maximizing the likelihood given the demonstrations. Yet, human demonstrations are often multi-modal, i.e., the same task is solved in multiple ways which is a major challenge for most imitation learning methods that are based on such a maximum likelihood (ML) objective. The ML objective forces the model to cover all data, it prevents specialization in the context space and can cause mode-averaging in the behavior space, leading to suboptimal or potentially catastrophic behavior. Here, we alleviate those issues by introducing a curriculum using a weight for each data point, allowing the model to specialize on data it can represent while incentivizing it to cover as much data as possible by an entropy bonus. We extend our algorithm to a Mixture of (linear) Experts (MoE) such that the single components can specialize on local context regions, while the MoE covers all data points. We evaluate our approach in complex simulated and real robot control tasks and show it learns from versatile human demonstrations and significantly outperforms current SOTA methods.
