description: Motivated by experimental results on the interplay between molecular motors and tau proteins, we extend lattice-based models of intracellular transport to include a second species of particle which locally influences the motor-filament attachment rate. We consider various exactly solvable limits of a stochastic multi-particle model before focusing on the low-motor-density regime. Here, an approximate treatment based on the random walk behaviour of single motors gives good quantitative agreement with simulation results for the tau-dependence of the motor current. Finally, we discuss the possible physiological implications of our results.

description: Tribe Clavigerini Leach, 1815
All Clavigeritae of Madagascar are currently assigned to the tribe Clavigerini as newly defined by Hlaváč et al. (2021). There are apparently four genera in this tribe which resemble each other and are easily separated from others. Ambrosiger Silvestri, 1926 (from Macao, China), Apoderiger, Micrapoderiger and Trymalius (all three from Madagascar) are all originally placed in the tribe Apoderigerini (Newton & Chandler, 1989). All these genera share a smooth surface of the forebody, trimerous antennae with the terminal antennomere very long and dilated distad to form a distal club, and the composite tergite lacking trichomes. Ambrosiger, Micrapoderiger and Trymalius are monogeneric and Apoderiger after this revision contains six species.

description: Auszug aus dem Einleitungskapitel:

„Sowohl von Studierenden als auch in wissenschaftlichen Studien wird immer wieder betont, wie wichtig Stimme und Sprechweise der Lehrperson für das Unterrichten sind. Jedoch wird nur an den wenigsten Hochschulen ein adäquates Stimm- und Sprechtraining während der Ausbildung angeboten. Auch später im Beruf scheint das Thema «Stimme» eher nebensächlich zu sein. Studien zeigen jedoch, dass ein intensives Stimmtraining von Nutzen ist, um zur nachhaltigen Gesunderhaltung und zur sprecherischen Ausdrucksfähigkeit der Stimme beizutragen. Denn schliesslich kann eine Lehrperson durch ihre Stimme Aufmerksamkeit erzeugen, trösten, leiten, beruhigen und schlichten, spannend erzählen, motivierend erklären und überzeugend argumentieren. Wenn es der Lehrperson gelingt, ihre Stimme physiologisch und variantenreich zu gebrauchen, kann sie optimal die verschiedenen Kommunikationssituationen im Klassenzimmer meistern und die Schülerinnen und Schüler lernförderlich durch das Unterrichtsgeschehen leiten –denn Sprechen und Stimme sind zentrales Medium im Unterricht! 

In dieser Broschüre geht es um das Thema «Stimme im Lehrberuf», welches aus verschiedenen Perspektiven beleuchtet wird. Dabei werden folgende Fragen geklärt:

• Warum sind Sprechen und Stimme entscheidende Wirkungsfaktoren beim Unterrichten?

• Warum ist die Stimm- und Sprechbildung – für (angehende) Lehrpersonen sowie Schülerinnen und Schüler – so wichtig?

• Wie kann eine Lehrperson sorgsam mit der Stimme umgehen und sie gezielt trainieren?

 Um diese Fragen zu beantworten, kommen eine Sprechbildnerin und eine Lehrerin ins Gespräch und fachsimpeln – eine jede aus ihrer Perspektive – zum Stimmgebrauch im Unterricht.“[S.3]

description: It is well known that Euler experimentally discovered the functional equation of the Riemann zeta function. Indeed he detected the fundamental $s\mapsto 1-s$ invariance of $ζ(s)$ by looking only at special values. In particular, via this functional equation, the permutation group on two letters, $S_2\simeq\Z/(2)$, is realized as a group of symmetries of $ζ(s)$. In this paper, we use the theory of special-values of our characteristic $p$ zeta functions to experimentally detect a natural symmetry group $S_{(q)}$ for these functions of cardinality ${\mathfrak c}=2^{\aleph_0}$ (where $\mathfrak c$ is the cardinality of the continuum); $S_{(q)}$ is a realization of the permutation group on $\{0,1,2...\}$ as homeomorphisms of $\Zp$ stabilizing both the nonpositive and nonnegative integers. We present a number of distinct instances in which $S_{(q)}$ acts (or appears to act) as symmetries of our functions. In particular, we present a natural, but highly mysterious, action of $S_{(q)}$ on a large subset of the domain of our functions that appears to stabilize zeta-zeroes. As of this writing, we do not yet know an overarching formalism that unifies these examples; however, it would seem that this formalism will involve an interplay between the 1-unit group $U_1$ -- playing the role of a "gauge group" -- and $S_{(q)}$. Furthermore, we show that $S_{(q)}$ may be naturally realized as an automorphism group of the convolution algebras of characteristic $p$ valued measures.
description: This the version that should appear in the proceedings of the conferences on noncommutative geometry (and I corrected a few small typos). Here we give direct evidence that our group S_{(q)} acts on zeta-zeroes with the 1-unit group, U_1, acting as a sort of "gauge group"

description: Resumo Previous studies of sediments from marine core GeoB 6211-2 collected at the upper margin of the Rio Grande Cone off Southern Brazil provided paleoenvironmental data of the last 14 ka (thousand years ago). These studies established the provenance of sediments associated with environmental changes, using grain-size distribution, diatom count, major element concentration, and magnetic methods. Our current study seeks a different approach to determine the provenance of these sediments by combining heavy mineral and quartz grain texture and luminescence data. Heavy minerals will be analyzed using the optical microscope and Raman spectrometry. Quartz-grain textures will be investigated by the optical microscope and the scanning electronic microscope (SEM). We plan to use two luminescence methods to establish the provenance of sediments using quartz grains. The first method is luminescence sensitivity, which is the luminescence intensity measured in response to a unit radioactive dose. This analysis will encompass optically stimulated luminescence and thermoluminescence sensitivities using multi- and single-grain aliquots in a RISO reader. The second luminescence method consists of hyperspectral cathodoluminescence analysis of selected quartz grains, using a cathodoluminescence system with a spectrometer attached to an SEM platform. A growing body of evidence shows that these luminescence methods provide data that can be related to the provenance of sediments. To illustrate the use of these grain analysis methods, we will show a preceding study conducted by André Zular on the provenance of sediments from an archeological site at the Negev desert, Israel.

description: The observed mass pattern of scalar resonances below 1 GeV gives preference to the tetraquark assignment over the conventional $\bar qq$ assignment for these states. We present a search for tetraquarks with isospins 0,1/2,1 in lattice QCD, where isospin channels 1/2 and 1 have not been studied before. Our simulation uses Chirally Improved fermions on quenched gauge configurations. We determine three energy levels for each isospin using the variational method. The ground state is consistent with the scattering state, while the two excited states have energy above 2 GeV. Therefore we find no indication for light tetraquarks at our range of pion masses 344-576 MeV.

description: RESUMO – Zircões magmáticos associados a rochas hidrotermalmente alteradas possuem assinaturas geoquímicas distintas em comparação aos grãos estritamente magmáticos. Parâmetros geoquímicos para caracterizar e interpretar a influência do hidrotermalismo na sua alteração e/ou gênese ainda estão em elaboração, com avanços notáveis na última década. Zircões de rochas do embasamento e de encaixantes dos depósitos arqueanos Furnas e Paulo Afonso, ambos de tipo IOCG (cobre-ouro-ferro oxidado), da Província Mineral de Carajás, possuem assinaturas geoquímicas anomalamente enriquecidas em U, Th e elementos terras raras (ETR). Estes depósitos estão localizados na porção norte da província e inseridos no contexto tectônico-estrutural da Zona de Cisalhamento do Cinzento, o mesmo em que se localizam a Mina do Salobo e os depósitos Igarapé Bahia e GT-46, dentre outros. Os dados em zircão de Furnas e Paulo Afonso indicaram populações distintas em termos de idade e assinaturas geoquímicas, onde se observa: (i) os zircões de ~2,75 Ga possuem feições magmáticas típicas, assim como o conteúdo de U e Th, com padrão hidrotermal ausente, ou mínimo; (ii) zircões de ~2,55 Ga possuem textura, morfologia e assinaturas geoquímicas para U, Th e ETR compatíveis com características hidrotermais e (iii) os zircões de ~1,88 Ga apresentam texturas magmáticas, enriquecimento em conteúdo de U, típico padrão magmático para ETR, mas com enriquecimento isolado destes elementos em alguns dos cristais analisados. Trabalhos prévios em Salobo, Igarapé Bahia e GT-46 mostram resultados similares aos obtidos nesta pesquisa, onde zircões de ~2,55 Ga têm assinaturas geoquímicas para U e Th análogas às de Furnas e Paulo Afonso, sendo diferentes das observadas nos grupos com idade ~2,75 Ga e ~1,9 Ga. Com isso, indicamos que estes zircões hidrotermais foram gerados regionalmente em ~2.55 Ga, sob condições geoquímicas similares e, possivelmente, por associação a movimentos tectônicos, mais do que ao magmatismo. Estes zircões hidrotermais de Furnas e Paulo Afonso estão relacionados com proeminentes depósitos IOCG, como Salobo e Igarapé Bahia, sugerindo circulação regional de fluidos hidrotermais com composição similar. Assim, indicamos o potencial do zircão para exploração mineral e seu uso como proxy para mineralização, por conta das assinaturas geoquímicas e texturas geradas pelo hidrotermalismo.

description: Resumo – The Eastern Cordillera, in the Colombian Northern Andes, registered high deformation rates during the Quaternary, influencing the drainage network evolution in combination with orographic precipitation. To unravel the late Pleistocene-Holocene interaction between climate and fault activity, we applied optically stimulated luminescence (OSL) dating on quartz grains extracted from sediments deposited in fluvial terraces and an alluvial fan in the medium reach of the Casanare River. The OSL sensitivity of the samples was also analyzed to further understand the sedimentary history of the fluvial basin. Fluvial terraces ages varied between 111.2 ± 16.8 and 13.1 ± 1.5 ka, while alluvial fan ages varied between 10.5 ± 2.4 and 1.5 ± 0.3 ka. Combining the resulting ages with elevation differences between sample and current thalweg positions, translate into incision rates of 14 to 9 m/ka, approximately one order of magnitude higher than previously reported exhumation rates for the Eastern Cordillera. OSL sensitivity increases for younger samples which can be interpreted as different sediment sources for the terraces and alluvial deposits or as an increase in sediment recycling within the alluvial fan, possibly due to higher sediment reworking than in the fluvial terraces. Alluvial fan ages in combination with the deformation produced by fault reactivation confirm that these structures have been active throughout the late Pleistocene-Holocene. The deposition timing suggests that receding glaciers and drainage reorganization drove sediment supply the river system, being deposited in the fluvial terraces between 111.2 and 13.1 ka ago. After 13.1 ka, the river system shifted from a period dominated by fluvial terrace aggradation into an incision phase. OSL sensitivity suggests that sediments from fluvial terraces where reworked and later deposited in the alluvial fan during the Holocene. Fault activity occurring after 10.5 ka controlled alluvial fan incision though nearby rivers still produce local alluvial aggradation by avulsion processes.

description: In this paper, we study properties of baryons by using a holographic dual of QCD on the basis of the D4/D8-brane configuration, where baryons are described by a soliton. We first determine the asymptotic behavior of the soliton solution, which allows us to evaluate well-defined currents associated with the U(N_f)_L \times U(N_f)_R chiral symmetry. Using the currents, we compute static quantities of baryons such as charge radii and magnetic moments, and make a quantitative test with experiments. It is emphasized that not only the nucleon but also excited baryons, such as Δ, N(1440), N(1535) etc., can be analyzed systematically in this model. We also investigate the form factors and find that our form factors agree well with the results that are well-established empirically. With the form factors, the effective baryon-baryon-meson cubic coupling constants among their infinite towers in the model can be determined. Some physical implications following from these results are discussed.

description: This paper provides a complete list of Krajewski diagrams representing the standard model of particle physics. We will give the possible representations of the algebra and the anomaly free lifts which provide the representation of the standard model gauge group on the fermionic Hilbert space. The algebra representations following from the Krajewski diagrams are not complete in the sense that the corresponding spectral triples do not necessarily obey to the axiom of Poincare duality. This defect may be repaired by adding new particles to the model, i.e. by building models beyond the standard model. The aim of this list of finite spectral triples (up to Poincare duality) is therefore to provide a basis for model building beyond the standard model.

description: In some galaxies, the central velocity dispersion, sigma, is depressed with respect to the surroundings. This sigma-drop phenomenon may have different physical origins, bearing information about the internal dynamics of the host galaxy. In this article, we stress the importance also of observational artifacts due to the sigma-metallicity degeneracy: when a spectrum of a population is compared with a template of miss-matched metallicity, the velocity dispersion may be wrongly estimated. A sigma-drop may appear in place of a metallicity peak. The discussion is illustrated using VLT/FORS spectra of diffuse elliptical galaxies. Some of the sigma-drop galaxies reported in the literature may be analysis artifacts.

description: Alexander Kaimberger geht in seinem luziden Artikel dem Begriff der Schleichwerbung nach, indem er einleitend nach dem Mediengesetz zwischen "ungekennzeichneter Werbung" und "unzureichend gekennzeichneter Werbung" unterscheidet. Dabei sucht er eine Antwort auf die Frage, was Medienunternehmen dazu verleitet, ihre gesellschaftliche Verantwortung zu unterwandern und sich auf das Spiel der Werbung einzulassen. Wird damit Information zum rein marktförmigen Gut? Kaimberger konstatiert eine bedenkliche Ökonomisierung der Printmedien, welche die sozioökonomischen, demokratiepolitischen und kulturellen Funktionen der Medien überdeckt und in den Hintergrund drängt. Insofern liegt mit diesem Artikel eine nachdrückliche Aufforderung zur Medienkritik im Sinne der Gesellschaftskritik vor. Dies betrifft die Felder der Werbung, der Public Relations und des Journalismus gleichermaßen.

description: We present a microscopic electronic description of how antiskyrmions can be stabilized in a Dresselhaus spin-orbit coupled magnetic metal. Furthermore, we show that the antiskyrmions can be tuned into Bloch skyrmions via a change in sign of hopping integral. The results are based on the state of the art hybrid Monte Carlo simulations. Origin of such topological textures is understood via an effective spin-only model. Our results uncover a novel connection between two very distinct topological spin textures of immense current interest, and present a microscopic explanation of skyrmion formation reported recently in certain magnetic Weyl semimetals.

description: Self-regulated learning (SRL) represents a critical educational framework through which learners proactively govern their learning processes using self-motivation, metacognitive reflection, and strategic task management. This article examines SRL’s transformative role in enhancing academic performance, particularly for underperforming students who often face significant academic and environmental challenges. SRL offers a structured approach for these students by promoting resilience and reinforcing goal-oriented learning behaviors. Key SRL components include establishing structured learning environments, optimizing resource use, and building self-efficacy. Through SRL instruction, educators can support underperformers in cultivating sustainable, autonomous learning practices. Specific strategies, such as peer tutoring and interactive tools like "Betty’s Brain," reinforce understanding as students teach and apply learned concepts. Integrating SRL among underperforming students cultivates lifelong learning skills and establishes a foundation for enduring academic and professional success. Future research should explore innovative SRL approaches tailored to the needs of underperforming students, with particular emphasis on applications within medical education, where SRL could significantly enhance both immediate and long-term outcomes.

description: Let M be a matroid representable over a (partial) field P and B a matrix representable over a sub-partial field P' of P. We say that B confines M to P' if, whenever a P-representation matrix A of M has a submatrix B, A is a scaled P'-matrix. We show that, under some conditions on the partial fields, on M, and on B, verifying whether B confines M to P' amounts to a finite check. A corollary of this result is Whittle's Stabilizer Theorem. A combination of the Confinement Theorem and the Lift Theorem from arXiv:0804.3263 leads to a short proof of Whittle's characterization of the matroids representable over GF(3) and other fields. We also use a combination of the Confinement Theorem and the Lift Theorem to prove a characterization, in terms of representability over partial fields, of the 3-connected matroids that have k inequivalent representations over GF(5), for k = 1, ..., 6. Additionally we give, for a fixed matroid M, an algebraic construction of a partial field P_M and a representation A over P_M such that every representation of M over a partial field P is equal to f(A) for some homomorphism f:P_M->P. Using the Confinement Theorem we prove an algebraic analog of the theory of free expansions by Geelen et al.

A linewidth in the order of around 100 Hz of the laser system has been measured with respect to an ultrastable 657 nm diode laser with 1 Hz linewidth using a femtosecond fiber comb as transfer oscillator. The laser has been used to measure the magnetically induced 1S0-3P0 clock transition in 88Sr where a linewidth of 165 Hz has been observed. The transfer oscillator method provides a virtual beat signal between the two diode lasers that has been used to phase lock the 698 nm laser to the 1 Hz linewidth laser at 657 nm, transferring its stability to the 698 nm laser system.

description: We develop a method of multifractal analysis of N-body cosmological simulations that improves on the customary counts-in-cells method by taking special care of the effects of discreteness and large scale homogeneity. The analysis of the Mare-Nostrum simulation with our method provides strong evidence of self-similar multifractal distributions of dark matter and gas, with a halo mass function that is of Press-Schechter type but has a power-law exponent -2, as corresponds to a multifractal. Furthermore, our analysis shows that the dark matter and gas distributions are indistinguishable as multifractals. To determine if there is any gas biasing, we calculate the cross-correlation coefficient, with negative but inconclusive results. Hence, we develop an effective Bayesian analysis connected with information theory, which clearly demonstrates that the gas is biased in a long range of scales, up to the scale of homogeneity. However, entropic measures related to the Bayesian analysis show that this gas bias is small (in a precise sense) and is such that the fractal singularities of both distributions coincide and are identical. We conclude that this common multifractal cosmic web structure is determined by the dynamics and is independent of the initial conditions.

description: Massive stars are strong sources of far-ultraviolet radiation that can be hostile to the evolution of protoplanetary disks, driving mass loss by external photoevaporation and shortening disk-dissipation timescales. Their effect may also reduce the timescale of angular momentum exchanges between the disk and host star during the early pre-main-sequence phase. To improve our understanding of the environmental influence on the rotational history of stars, we developed a model that considers the influence of the local far-ultraviolet radiation on the spin evolution of low mass stars. Our model includes an assumption of disk-locking, which fixes the rotation rate during the star-disk-interaction phase, with the duration of this phase parametrised as a function of the local far-ultraviolet radiation and stellar mass (in the range 0.1--1.3 M$_\odot$). In this way, we demonstrate how the feedback from massive stars can significantly influence the spin evolution of stars and explain the mass-dependency observed in period-mass distributions of young regions like Upper Sco and NGC 2264. The high far-ultraviolet environments of high-mass stars can skew the period distribution of surrounding stars towards fast-rotation, explaining the excess of fast-rotating stars in the open cluster h Per. The proposed link between rotation and the pre-main-sequence environment opens new avenues for interpreting the rotational distributions of young stars. For example, we suggest that stellar rotation may be used as a tracer for the primordial ultraviolet irradiation for stars up to $\sim$1 Gyr, which offers a potential method to connect mature planetary systems to their birth environment.

description: We study how well magnetic models can be implemented with ultracold bosonic atoms of two different hyperfine states in an optical superlattice. The system is captured by a two-species Bose-Hubbard model, but realizes in a certain parameter regime actually the physics of a spin-1/2 Heisenberg magnet, describing the second order hopping processes. Tuning of the superlattice allows for controlling the effect of fast first order processes versus the slower second order ones. Using the density-matrix renormalization-group method, we provide the evolution of typical experimentally available observables. The validity of the description via the Heisenberg model, depending on the parameters of the Hubbard model, is studied numerically and analytically. The analysis is also motivated by recent experiments [S. Foelling et al., Nature 448, 1029 (2007); S. Trotzky et al., Sience 319, 295 (2008)] where coherent two-particle dynamics with ultracold bosonic atoms in isolated double wells were realized. We provide theoretical background for the next step, the observation of coherent many-particle dynamics after coupling the double wells. Contrary to the case of isolated double wells, relaxation of local observables can be observed. The tunability between the Bose-Hubbard model and the Heisenberg model in this setup could be used to study experimentally the differences in equilibration processes for nonintegrable and Bethe ansatz integrable models. We show that the relaxation in the Heisenberg model is connected to a phase averaging effect, which is in contrast to the typical scattering driven thermalization in nonintegrable models. We discuss the preparation of magnetic groundstates by adiabatic tuning of the superlattice parameters.

description: An initial-value problem for arbitrary small 3D vorticity perturbations imposed on a free shear flow is considered. The viscous perturbation equations are then combined in terms of the vorticity and velocity, and are solved by means of a combined Laplace-Fourier transform in the plane normal to the basic flow. This treatment allows for a simplification of the governing equations such that it is possible to observe long transients, that can last hundreds time scales. This result would not be possible over an acceptable lapse of time by carrying out a direct numerical integration of the linearized Navier-Stokes equations. The exploration is done with respect to physical inputs as the angle of obliquity, the symmetry of the perturbation and the streamwise damping rate. The base flow is an intermediate section of the growing 2D circular cylinder wake where the entrainment process is still active. Two Reynolds numbers of the order of the critical value for the onset of the first instability are considered. The early transient evolution offers very different scenarios for which we present a summary for particular cases. For example, for amplified perturbations, we have observed two kinds of transients, namely (1) a monotone amplification and (2) a sequence of growth - decrease - final growth. In the latter case, if the initial condition is an asymmetric oblique or longitudinal perturbation, the transient clearly shows an initial oscillatory time scale. Furthermore, the more a perturbation is longitudinally confined the more it is amplified in time. The long-term behavior of two-dimensional disturbances shows excellent agreement with a recent two-dimensional spatio-temporal multiscale modal analysis and with laboratory data concerning the frequency and wave length of the parallel vortex shedding in the cylinder wake.

description: Virtual Reality applications are becoming increasingly mature. The requirements and complexity of such systems is steadily increasing. Realistic and detailed environments are often omitted in order to concentrate on the interaction possibilities within the application. Creating an accurate and realistic virtual environment is not a task for laypeople, but for experts in 3D design and modeling. To save costs and avoid hiring experts, panorama images are often used to create realistic looking virtual environments. These images can be captured and provided by non-experts. Panorama images are an alternative to handcrafted 3D models in many cases because they offer immersion and a scene can be captured in great detail with the touch of a button. This work investigates whether it is advisable to recreate an environment in detail by hand or whether it is recommended to use panorama images for virtual environments in certain scenarios. For this purpose, an interactive virtual environment was created in which a handmade 3D environment is almost indistinguishable from an environment created with panorama images. Interactive elements were added and a user study was conducted to investigate the effect of both environments to the user. The study conducted indicates that panorama images can be a useful substitute for 3D modeled environments.

description: The calculations of the potential energy surface are essential in the theoretical description of the fission process. In the constrained self-consistent approach, the smooth evolution of nuclear shape is described from the ground state until a very elongated one with a narrow neck. In all microscopic calculations, the rupture of the neck at scission is associated with a substantial change of nuclear matter density distribution and rapid energy decrease. In this paper, we show that there is no discontinuity of the potential energy surface at scission when multi-constrained calculations are applied with the neck constraint. An early rupture of the neck at lower quadrupole and octupole moments is discussed as competitive with the conventional fission path. We discuss the neck properties in the scission configuration. We find that the neck radius in the asymmetric fission mode cannot decrease below 2 fm, and the nuclear matter density cannot decrease below the saturation density. In the compact fission mode, nuclear density may go down to half of the saturation density before the rupture of the neck.
