description: A single graphene layer placed between two parallel Ni(111) surfaces screens the strong attractive force and results in a significant reduction of adhesion and sliding friction. When two graphene layers are inserted, each graphene is attached to one of the metal surfaces with a significant binding and reduces the adhesion further. In the sliding motion of these surfaces the transition from stick-slip to continuous sliding is attained, whereby non-equilibrium phonon generation through sudden processes is suppressed. The adhesion and corrugation strength continues to decrease upon insertion of the third graphene layer and eventually saturates at a constant value with increasing number of graphene layers. In the absence of Ni surfaces, the corrugation strength of multilayered graphene is relatively higher and practically independent of the number of layers. Present first-principles calculations reveal the superlubricant feature of graphene layers placed between pseudomorphic Ni(111) surfaces, which is achieved through the coupling of Ni-3d and graphene-$π$ orbitals. The effect of graphene layers inserted between a pair of parallel Cu(111) and Al(111) surfaces are also discussed. The treatment of sliding friction under the constant loading force, by taking into account the deformations corresponding to any relative positions of sliding slabs, is the unique feature of our study.

description: SQUID arrays are promising candidates for low profile antennas and low noise amplifier applications. We present the integrated circuit designs and results of DC and RF measurements of the wideband serial arrays based on integration of linear bi-SQUID cells forming a Superconducting Quantum Interference Filter (bi-SQUID SQIF). Various configurations of serial arrays designs are described. The measured linearity, power gain, and noise temperature are analyzed and compared. The experimental results are matched to results of mathematical modeling. A serial bi-SQUID SQIF arrays are mounted into a coplanar waveguide (CPW) and symmetrically grounded to corresponding sides of CPW. The RF output comes out from the central common line, which is also used for DC biasing and forms a symmetrical balanced output. The signal and DC flux biasing line is designed as coplanar lines passed in parallel over each bi-SQUID cell in a bidirectional fashion concentrating magnetic flux inside of each cell. Serial bi-SQUID SQIF arrays are fabricated on 5 mm x 5 mm chips using standard HYPRES niobium 4.5 kA/cm2 fabrication process.

description: Due to the rising number of offshore structures all over the world, underwater wet welding has become increasingly relevant, mainly as a repair method. Welding in direct contact with water involves numerous challenges. A topic focused by many studies is the risk of hydrogen-induced cracking in wet weldments due to hardness values of up to 500 HV 0.2 in the heat-affected zone (HAZ) and high levels of diffusible hydrogen in the weld metal. The risk of cracking increases as the equivalent carbon content rises, because the potential to form martensitic structures within the HAZ rises too. Thus, high-strength steels are especially prone to hydrogen-induced cracking and are considered unsafe for underwater wet repair weldments. © 2020 The Authors.

Autoregressive Diffusion with Retentive Networks for Image and Audio Generation
Creators: name: Albers, Josef
Publisher: name: Zenodo
Year: 2024

description: This paper introduces a novel approach to generative modeling that combines autoregressive diffusion processes with Retentive Networks (RetNet) for both image and audio generation. Our method, termed Autoregressive Diffusion with Retention (ADR), leverages the dual-mode capability of RetNet to achieve efficient parallel processing during training while enabling fast autoregressive generation through recurrent computation during inference. This approach demonstrates promising results in generating high-quality images and audio samples while potentially reducing computational complexity and improving scalability. We evaluate our model on standard datasets and discuss the implications of this approach for the broader field of generative AI.

description: Exact analytical, closed-form solutions, expressed in terms of special functions, are presented for the case of a three-dimensional nonlinear quantum oscillator with a position dependent mass. This system is the generalization of the corresponding one-dimensional system, which has been the focus of recent attention. In contrast to other approaches, we are able to obtain solutions in terms of special functions, without a reliance upon a Rodrigues-type of formula. The wave functions of the quantum oscillator have the familiar spherical harmonic solutions for the angular part. For the s-states of the system, the radial equation accepts solutions that have been recently found for the one-dimensional nonlinear quantum oscillator, given in terms of associated Legendre functions, along with a constant shift in the energy eigenvalues. Radial solutions are obtained for all angular momentum states, along with the complete energy spectrum of the bound states.

Directionally 2-Signed and Bidirected Graphs

description: An edge uv in a graph Γ is directionally 2-signed (or, (2,d)-signed) by an ordered pair (a,b), a,b in {+,-}, if the label l(uv) = (a,b) from u to v, and l(vu) = (b,a) from v to u. Directionally 2-signed graphs are equivalent to bidirected graphs, where each end of an edge has a sign. A bidirected graph implies a signed graph, where each edge has a sign. We extend a theorem of Sriraj and Sampathkumar by proving that the signed graph is antibalanced (all even cycles and only even cycles have positive edge sign product) if, and only if, in the bidirected graph, after suitable reorientation of edges every vertex is a source or a sink.

description: Intense, ultrashort laser pulses are required for the study of many nonlinear optical effects and are of utmost relevance for various applications from ultrafast X-ray radiography in medicine up to remote sensing of the atmosphere. Increasing their intensity while interacting with matter eventually leads to the generation of laser-induced plasma. This plasma has fascinating optical properties such as a negative refractive index contribution proportional to the free electron density or the lack of a damage threshold, giving the prospect of a multitude of new applications based on the manipulation of light with plasma. The realization of such plasma-based applications requires a precise knowledge of its properties and temporal evolution, as the plasma remains for much longer than its generation event. A method to generate and investigate ultrashort laser pulses as well as laser-induced plasma is femtosecond filamentation. It represents the formation of an intense self-guided light channel in a medium for distances much longer than the Rayleigh range of the same beam focused in vacuum. It is formed by a dynamic balance of Kerr-induced self-focusing and plasma-induced defocusing. In this thesis, it is demonstrated that femtosecond filamentation can be employed as a tool to investigate the temporal evolution of laser-induced plasma. The study is realized in various atomic and molecular gas atmospheres via measuring the temporal evolution of the enhancement of third harmonic radiation generated by a femtosecond filament which is intercepted by a laser-induced plasma spot. Significant differences for the lifetime of the plasma in atomic and molecular gas atmospheres are found. Further, a novel method for the complete spatio-temporal characterization of a femtosecond filament along its length is presented. It is based on controlled filament termination at various positions along its length in combination with spatio-temporal pulse characterization and numerical backpropagation of the filament pulses to the termination point. The capabilities of the method are illustrated by revealing complex spatio-temporal dynamics and couplings during filament propagation.

description: In this paper we discuss some connections between groupoids and Frobenius algebras specialized in the case of Poisson sigma models with boundary. We prove a correspondence between groupoids in the category Set and relative Frobenius algebras in the category Rel, as well as an adjunction between a special type of semigroupoids and relative H*-algebras. The connection between groupoids and Frobenius algebras is made explicit by introducing what we called weak monoids and relational symplectic groupoids, in the context of Poisson sigma models with boundary and in particular, describing such structures in the ex- tended symplectic category and the category of Hilbert spaces. This is part of a joint work with Alberto Cattaneo and Chris Heunen.

description: Die Dissertation befasst sich mit den Ursachen, den Folgen und dem Wandel der traditionellen Arbeitsteilung in Partnerschaften von Akademikerinnen und Akademikern in Deutschland. Die übergreifende Forschungsfrage ist, welche Auswirkungen die traditionelle Arbeitsteilung infolge der Familiengründung auf die Erwerbsverläufe von Männern und Frauen mit Hochschulabschluss hat. Der Fokus auf Personen mit Hochschulabschluss liegt darin begründet, dass diese Gruppe überdurchschnittlich progressive Werthaltungen mitbringt und als Initiator sozialen Wandels gilt. Aus einer lebensverlaufstheoretischen Perspektive und mit humankapitaltheoretischen und geschlechterrollentheoretischen Erklärungen, werden verschiedene Aspekte der traditionellen Arbeitsteilung untersucht. Es werden die Aushandlungen der Elternzeitverteilung von Paaren zur Ergründung von Ursachen der traditionellen Arbeitsteilung, die Einkommensdifferenz von Männern und Frauen, als eine Folge der traditionellen Arbeitsteilung, sowie Veränderungen der Lebenslaufsmuster von Müttern und Vätern, als Hinweise auf einen Wandel der traditionellen Arbeitsteilung, behandelt. Für die empirischen Analysen werden die Daten der bundesweit repräsentativen DZHW-Absolventenpanel der Abschlussjahrgänge 1997, 2001 und 2005 genutzt. Diese umfassen insgesamt rund 14.500 Hochschulabsolvent(inn)en und deren berufliche und familiale Verläufe über einen Zeitraum von rund zehn Jahren nach dem Abschluss des Studiums. Die Analyseverfahren sind jeweils auf den Untersuchungsgegenstand angepasst und umfassen multivariate Regressionsmodelle, Effektzerlegungen und Sequenzanalysen.

In particular, if $w\in C^d_{2t}\cap A_{\infty}^d$ then $w^{2t}\in A_q^d$ for some $q>1$.

description: To improve the bond strength of hybrid components when joined by friction welding, specimens with various front end surface geometries were evaluated. Rods made of aluminum AA6082 (AlSi1MgMn/EN AW-6082) and the case-hardening steel 20MnCr5 (AISI 5120) with adapted joining surface geometries were investigated to create both a form-locked and material-bonded joint. Eight different geometries were selected and tested. Subsequently, the joined components were metallographically examined to analyze the bonding and the resulting microstructures. The mechanical properties were tested by means of tensile tests and hardness measurements. Three geometrical variants with different locking types were identified as the most promising for further processing in a forming process chain due to the observed material bond and tensile strengths above 220 MPa. The hardness tests revealed an increase in the steel’s hardness and a softening of the aluminum near the transition area. Apparent intermetallic phases in the joining zone were analyzed by scanning electron microscopy (SEM) and an accumulation of silicon in the joining zone was detected by energy-dispersive X-ray spectroscopy (EDS). © 2021 by the authors.

description: Single-crystalline Bi2Te2Se nanoplates with thicknesses between 8 and 30 nm and lateral sizes of several micrometers were synthesized by a vapour-solid growth method. Angle-dependent magnetoconductance measurements on individual nanoplates revealed the presence of a two-dimensional weak anti-localization effect. In conjunction with gate-dependent charge transport studies performed at different temperatures, evidence was gained that this effect originates from the topologically protected surface states of the nanoplates.

description: We present the first high-angular resolution survey for multiple systems among very low-mass stars and brown dwarfs in the Hyades open cluster. Using the Keck\,II adaptive optics system, we observed a complete sample of 16 objects with estimated masses $\lesssim$0.1 Msun. We have identified three close binaries with projected separation $\lesssim$0.11", or $\lesssim$5 AU. A number of wide, mostly faint candidate companions are also detected in our images, most of which are revealed as unrelated background sources based on astrometric and/or photometric considerations. The derived multiplicity frequency, 19+13/-6 % over the 2-350 AU range, and the rarity of systems wider than 10 AU are both consistent with observations of field very low-mass objects. In the limited 3-50 AU separation range, the companion frequency is essentially constant from brown dwarfs to solar-type stars in the Hyades cluster, which is also in line with our current knowledge for field stars. Combining the binaries discovered in this surveys with those already known in the Pleiades cluster reveals that very low-mass binaries in open clusters, as well as in star-forming regions, are skewed toward lower mass ratios ($0.6 \lesssim q \lesssim 0.8$) than are their field counterparts, a result that cannot be accounted for by selection effects. Although the possibility of severe systematic errors in model-based mass estimates for very low-mass stars cannot be completely excluded, it is unlikely to explain this difference. We speculate that this trend indicates that surveys among very low-mass field stars may have missed a substantial population of intermediate mass ratio systems, implying that these systems are more common and more diverse than previously thought.

Origin of symmetry energy in finite nuclei and density dependence of nuclear matter symmetry energy from measured alpha-decay energies

description: Based on the Skyrme energy density functional, the spatial distribution of the symmetry energy of a finite nucleus is derived in order to examine whether the symmetry energy of a finite nucleus originates from its interior or from its surface. It is found that the surface part of a heavy nucleus contributes dominantly to its symmetry energy compared to its inner part. The symmetry energy coefficient $a_{\text{sym}}({A})$ is then directly extracted and the ratio of the surface symmetry coefficient to the volume symmetry coefficient $κ$ is estimated. Meanwhile, with the help of experimental alpha decay energies, a macroscopic method is developed to determine the symmetry energy coefficient of heavy nuclei. The resultant $a_{\text{sym}}({A})$ is used to analyze the density dependence of the symmetry energy coefficient of nuclear matter around the saturation density, and furthermore, the neutron skin thickness of $^{208}\text{Pb}$ is deduced which is consistent with the pygmy dipole resonance analysis. In addition, it is shown that the ratio $κ$ obtained from the macroscopic method is in agreement with that from the Skyrme energy density functional. Thus the two completely different approaches may validate each other to achieve more compelling results.

description: Il volume propone una riflessione collettiva sulle città intese come soggetti istituzionali che assumono sempre maggiore rilevanza pubblica. Le città, quali enti di autogoverno locale più prossimi alle cittadinanze, ricoprono un ruolo centrale nelle dinamiche multilivello degli Stati costituzionali contemporanei e rappresentano spesso l’istituzione giuridico-politica che per prima si confronta con gli accelerati mutamenti dell’epoca globale e digitale.
I saggi che compongono il volume tengono insieme profili costituzionalistici, sensibilità storica e analisi comparata e interrogano il contesto urbano nelle sue diverse prospettive, come spazio giuridico di conflitto, mediazione e trasformazione sociale, evidenziando criticità e opportunità: da domande di nuova regolazione e partecipazione, a esigenze di autonomia e libertà che caratterizzano la storia, plurale e molteplice, del costituzionalismo moderno e contemporaneo. A partire dalle città del presente e del futuro.

description: This paper focuses on the awareness, use, satisfaction and problems regarding the available library resources at Dronacharya College of Engineering. In this study, the perspectives of teachers and students were compared side by side. To collect data from 400 targeted samples (350 students and 50 teachers) with the help of a structured questionnaire designed to cover all possible aspects required to fulfil the study objectives using the descriptive survey method. Based on the responses of 236 valid respondents (59.00%), it can be inferred that although the library offers a sizable collection of print and electronic resources, it is somewhat short on valued and updated materials. Besides, students put the internet facility into serious question. Overall, the teachers are neutrally satisfied with the collection and the students are satisfied enough. Updated collection, demand driven acquisition, expanded internet access, and awareness campaigns are just a few suggested actions that could improve user satisfaction and the effective use of library resources.

description: Phylogenetic analyses of gene expression have great potential for addressing a wide range of questions. These analyses will, for example, identify genes that have evolutionary shifts in expression that are correlated with evolutionary changes in morphological, physiological, and developmental characters of interest. This will provide entirely new opportunities to identify genes related to particular phenotypes. There are, however, three key challenges that must be addressed for such studies to realize their potential. First, gene expression data must be measured from multiple species, some of which may be field collected, and parameterized in such a way that they can be compared across species. Second, it will be necessary to develop phylogenetic comparative methods suitable for large multidimensional datasets. In most phylogenetic comparative studies to date, the number n of independent observations (independent contrasts) has been greater than the number p of variables (characters). The behavior of comparative methods for these classic n>p problems are now well understood under a wide variety of conditions. In gene expression studies, and studies based on other high-throughput tools, the number n of samples is dwarfed by the number p of variables. The estimated covariance matrices will be singular, complicating their analysis and interpretation, and prone to spurious results. Third, new approaches are needed to investigate the expression of the many genes whose phylogenies are not congruent with species phylogenies due to gene loss, gene duplication, and incomplete lineage sorting. Here we outline general project design considerations for phylogenetic analyses of gene expression, and suggest solutions to these three categories of challenges. These topics are relevant to high-throughput phenotypic data well beyond gene expression.

description: Expectations are among the main driving forces for economic dynamics. Therefore, managing expectations has become a primary objective for monetary policy seeking to stabilize the business cycle. In this paper, we study whether central banks can manage private-sector expectations by means of publishing one-period ahead inflation projections in a New Keynesian learning-to-forecast experiment. Subjects in the experiment observe these projections along with the historic development of the economy and subsequently submit their own one-period ahead inflation forecasts. In this context, we find that the central bank can significantly manage private-sector expectations and that this management strongly supports monetary policy in stabilizing the economy. Moreover, published central bank inflation projections drastically reduce the probability of a deflationary spiral after strong negative shocks to the economy.

description: Coughs sounds have shown promising as-potential marker for distinguishing COVID individuals from non-COVID ones. In this paper, we propose an attention-based ensemble learning approach to learn complementary representations from cough samples. Unlike most traditional schemes such as mere maxing or averaging, the proposed approach fairly considers the contribution of the representation generated by each single model. The attention mechanism is further investigated at the feature level and the decision level. Evaluated on the Track-1 test set of the DiCOVA challenge 2021, the experimental results demonstrate that the proposed feature-level attention-based ensemble learning achieves the best performance (Area Under Curve, AUC: 77.96%), resulting in an 8.05% improvement over the challenge baseline. ©

description: *Context The evolution of young massive protoplanetary disks toward planetary systems is expected to include the formation of gaps and the depletion of dust and gas. *Aims A special group of flaring disks around Herbig Ae/Be stars do not show prominent silicate emission features. We focus our attention on four key Herbig Ae/Be stars to understand the structural properties responsible for the absence of silicate feature emission. *Methods We investigate Q- and N-band images taken with Subaru/COMICS, Gemini South/T-ReCS and VLT/VISIR. Our radiative transfer modeling solutions require a separation of inner- and outer- disks by a large gap. From this we characterize the radial density structure of dust and PAHs in the disk. *Results The inner edge of the outer disk has a high surface brightness and a typical temperature between ~100-150 K and therefore dominates the emission in the Q-band. We derive radii of the inner edge of the outer disk of 34, 23, 30 and 63 AU for HD97048, HD169142, HD135344B and Oph IRS 48 respectively. For HD97048 this is the first detection of a disk gap. The continuum emission in the N-band is not due to emission in the wings of PAHs. This continuum emission can be due to VSGs or to thermal emission from the inner disk. We find that PAH emission is not always dominated by PAHs on the surface of the outer disk. *Conclusions. The absence of silicate emission features is due to the presence of large gaps in the critical temperature regime. Many, if not all Herbig disks with Spectral Energy Distribution (SED) classification `group I' are disks with large gaps and can be characterized as (pre-) transitional. An evolutionary path from the observed group I to the observed group II sources seems no longer likely. Instead, both might derive from a common ancestor.

Momentum Dependent Local-Ansatz with Hybrid Wavefunction from Weak to Strong Electron Correlations

description: The variational theory of momentum dependent local-ansatz (MLA) has been generalized by introducing a hybrid (HB) wavefunction as a starting wavefunction, whose potential can flexibly change from the Hartree-Fock type to the alloy-analogy type by varying a weighting factor from zero to one. Numerical results based on the half-filled band Hubbard model on the hypercubic lattice in infinite dimensions show up that the new wavefunction yields the ground-state energy lower than that of the Gutzwiller wavefunction (GW) in the whole Coulomb interaction regime. Calculated double occupation number is smaller than the result of the GW in the weak Coulomb interaction regime, and remains finite in the strong regime. Furthermore, the momentum distribution shows a distinct momentum dependence, which is qualitatively different from that of the GW.

description: A new synthetic access to the Lewis acid [Au(OTeF5)3] and the preparation of the related, unprecedented anion [Au(OTeF5)4]− with inorganic or organic cations starting from commercially available and easy-to-handle gold chlorides are presented. In this first extensive study of the Lewis acidity of a transition metal teflate complex using different experimental and quantum chemical methods, [Au(OTeF5)3] was classified as a Lewis superacid. The solid state structure of the triphenylphosphane adduct [Au(OPPh3)(OTeF5)3] was determined, representing the first structural characterization of an adduct of this highly reactive [Au(OTeF5)3]. Therein, the coordination environment around the gold center slightly deviates from the typical square planar geometry. The related, unprecedented anion [Au(OTeF5)4]− shows a similar coordination motif.
