description: Im Praxissemester sind Mentor*innen für Studierende wichtige Bezugspersonen und Kooperationspartner*innen, die die Studierenden u.a. bei der Planung, Durchführung und Reflexion von Unterricht begleiten. Während z.B. zur Kompetenzentwicklung Studierender im Praxissemester mehrere Erkenntnisse vorliegen, wurde die Perspektive von Mentor*innen bisher wenig untersucht. Dieser Beitrag zielt darauf, die Perspektive und Erfahrungen von Mentor*innen zu explorieren und sichtbar zu machen. In diesem Zusammenhang werden Ergebnisse einer leitfadenzentrierten Interviewstudie vorgestellt, an der 23 nordrhein-westfälische Lehrkräfte teilnahmen. Auf Grundlage der inhaltsanalytischen Auswertung der Transkripte werden die nachstehenden Fragestellungen beantwortet: (1) Was sind aus Sicht von Mentor*innen Aufgaben im Zusammenhang mit der Betreuung und Begleitung von Praxissemesterstudierenden?, (2) Welche Ziele haben Praxisphasen aus der Perspektive der Mentor*innen?, (3) Welchen Betreuungsstrategien folgen Mentor*innen bei der Betreuung und Begleitung von Praxissemesterstudierenden? Die Ergebnisse zeigen, dass die Antworten der Mentor*innen hinsichtlich der ihnen selbst zugeschriebenen Aufgaben und der dem Praxissemester attribuierten Ziele kaum differieren. Die Betreuungsstrategien der Befragten unterscheiden sich hingegen vergleichsweise stark. Unterschiede bestehen u.a. bezüglich der den Studierenden zugesprochenen Freiheitsgrade bei der Unterrichtsplanung und -durchführung sowie bei der (gemeinsamen) Gestaltung der Unterrichtsplanung bzw. -vorbesprechung.

description: A Richman game is a combinatorial game in which, rather than alternating moves, the two players bid for the privilege of making the next move. We consider both the case where the players pay each other and the case where the players pay a neutral third party. We find optimal strategies considering both the case where the players know how much money their opponent has and the case where they do not.

Remarks.
The 38 specimens from the Aldabra Atoll (from Cinq Cases, Malabar, and Picard) for which sex can reliably be determined are all females, such that the population is parthenogenetic. They are likely conspecific with L. tristani as described from the Chagos Archipelago (Popovici et al. 2024), sharing the distinctly reduced spinous process on the tibia of leg pair 12, often taking the form of a rounded bump (Fig. 1 C). The stability of this character is however uncertain as specimens from localities in the Aldabra Atoll exhibit conspicuous variation in the shape of the process (Fig. 1 D, Table 1). Additional similarities between these two populations include the morphology of the forcipular coxosternite (Fig. 1 A, B), the number of antennal articles, and the number and shape of the spurs on the female gonopods (Fig. 1 E). Variability in the characters of antennal article number, number, and distribution of coxal pores and shape of the distal spinous process on the tibia of leg pair 12 are listed in Table 1 and compared with putatively conspecific individuals from the Chagos Archipelago, excluding anamorphic stages.

A simple interpretation of quantum mirages

Year: 2000
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: In an interesting new experiment the electronic structure of a magnetic atom adsorbed on the surface of Cu(111), observed by STM, was projected into a remote location on the same surface. The purpose of the present paper is to interpret this experiment with a model Hamiltonian, using ellipses of the size of the experimental ones, containing about 2300 atoms. The charge distribution for the different wavefunctions is analyzed, in particular, for those with energy close to the Fermi energy of copper Ef. Some of them show two symmetric maxima located on the principal axis of the ellipse but not necessarily at the foci. If a Co atom is adsorbed at the site where the wavefunction with energy $E_F$ has a maximum and the interaction is small, the main effect of the adsorbed atom will be to split this particular wavefunction in two. The total charge density will remain the same but the local density of states will present a dip at Ef at any site where the charge density is large enough. We relate the presence of this dip to the observation of quantum mirages. Our interpretation suggests that other sites, apart from the foci of the ellipses, can be used for projecting atomic images and also indicates the conditions for other non magnetic adsorbates to produce mirages.

description: The analysis of extensive numerical data for the percolation probabilities of incipient spanning clusters in two dimensional percolation at criticality are presented. We developed an effective code for the single-scan version of the Hoshen-Kopelman algorithm. We measured the probabilities on the square lattice forming samples of rectangular strips with widths from 8 to 256 sites and lengths up to 3200 sites. At total of more than $10^{15}$ random numbers are generated for the sampling procedure. Our data confirm the proposed exact formulaes for the probability exponents conjectured recently on the base of 2D conformal field theory. Some preliminary results for 3D percolation are also discussed.

description: We employ nonperturbative flow equations to compute the equation of state for two flavor QCD within an effective quark meson model. This yields the temperature and quark mass dependence of quantities like the chiral condensate or the pion mass. A precision estimate of the universal critical equation of state for the three-dimensional O(4) Heisenberg model is presented. We explicitly connect the O(4) universal behavior near the critical temperature and zero quark mass with the physics at zero temperature and a realistic pion mass. For realistic quark masses the pion correlation length near T_c turns out to be smaller than its zero temperature value.

description: We re-examine the nature of the ground states of bilayer graphene at odd integer filling factors within a simplified model of nearly degenerate $n=0$ and $n=1$ Landau levels. Previous Hartree-Fock studies have found that ferroelectric states with orbital coherence can be stabilized by tuning the orbital splitting between these levels. These studies indicated that, in addition to a uniform ferroelectric state, a helical ferroelectric phase with spontaneously broken translational symmetry is possible. By performing exact diagonalization on the torus, we argue that the system does not have a uniform coherent state but instead transitions directly from the uniform incoherent state into the ferroelectric helical phase. We argue that there is a realistic prospect to stabilize the helical ferroelectric state in bilayer graphene by tuning the interlayer electric field in a model that includes all single particle corrections to its zero energy eight-fold multiplet of Landau levels.

description: It is shown that the partition function of the 2d Ising model on the dual finite lattice with periodical boundary conditions is expressed through some specific combination of the partition functions of the model on the torus with corresponding boundary conditions. The generalization of the duality relations for the nonhomogeneous case is given. These relations are proved for the weakly-nonhomogeneous distribution of the coupling constants for the finite lattice of arbitrary sizes. Using the duality relations for the nonhomogeneous Ising model, we obtain the duality relations for the two-point correlation function on the torus, the 2d Ising model with magnetic fields applied to the boundaries and the 2d Ising model with free, fixed and mixed boundary conditions.

description: A $\mathcal G$-system is a collection of $\mathbb Z$-bases of $\mathbb Z^n$ with some extra axiomatic conditions. There are two kinds of actions "mutations" and "co-Bongartz completions" naturally acting on a $\mathcal G$-system, which provide the combinatorial structure of a $\mathcal G$-system. It turns out that "co-Bongartz completions" have good compatibility with "mutations". The constructions of "mutations" are known before in different contexts, including cluster tilting theory, silting theory, $τ$-tilting theory, cluster algebras, marked surfaces. We found that in addition to "mutations", there exists another kind of actions "co-Bongartz completions" naturally appearing in these different theories. With the help of "co-Bongartz completions" some good combinatorial results can be easily obtained. In this paper, we give the constructions of "co-Bongartz completions" in different theories. Then we show that $\mathcal G$-systems naturally arise from these theories, and the "mutations" and "co-Bongartz completions" in different theories are compatible with those in $\mathcal G$-systems.

description: The advent of Machine-to-Machine communication has sparked a new wave of interest to random access protocols, especially in application to LTE Random Access (RA). By analogy with classical slotted ALOHA, state-of-the-art models LTE RA as a multi-channel slotted ALOHA. In this letter, we direct the attention to the resource consumption of RA. We show that the consumption is a random variable dependent on the contention parameters. We consider two approaches to include the consumption into RA optimization: by defining resource efficiency and by the means of a bi-objective optimization, where resource consumption and throughput are the competing objectives. We then develop the algorithm to obtain Pareto-optimal RA configuration under resource constraint. We show that the algorithm achieves lower burst resolution delay and higher throughput than the state-of-the-art.

description: We present an analysis of Chandra spectra of five gravitationally lensed active galactic nuclei. We confirm the previous detections of FeK$α$ emission lines in most images of these objects with high significance. The line energies range from 5.8 to 6.8 keV with widths from unresolved to 0.6 keV, consistent with emission close to spinning black holes viewed at different inclination angles. We also confirm the positive offset from the Iwasawa-Taniguchi effect, the inverse correlation between the FeK$α$ equivalent width and the X-ray luminosity in AGN, where our measured equivalent widths are larger in lensed quasars. We attribute this effect to microlensing, and perform a microlensing likelihood analysis to constrain the emission size of the relativistic reflection region and the spin of supermassive black holes, assuming that the X-ray corona and the reflection region, responsible for the iron emission line, both follow power-law emissivity profiles. The microlensing analysis yields strong constraints on the spin and emissivity index of the reflection component for Q2237+0305, with $a > 0.92$ and $n > 5.4$. For the remaining four targets, we jointly constrain the two parameters, yielding $a=0.8\pm0.16$ and an emissivity index of $n=4.0\pm 0.8$, suggesting that the relativistic X-ray reflection region is ultra-compact and very close to the innermost stable circular orbits of black holes, which are spinning at close to the maximal value. We successfully constrain the half light radius of the emission region to $< 2.4$ $r_g$ ($r_g = GM/c^2$) for Q2237+0305 and in the range 5.9--7.4 $r_g$ for the joint sample.

description: We perform molecular dynamics simulations of an idealized polymer melt surrounding a nanoscopic filler particle to probe the effects of a filler on the local melt structure and dynamics. We show that the glass transition temperature $T_g$ of the melt can be shifted to either higher or lower temperatures by appropriately tuning the interactions between polymer and filler. A gradual change of the polymer dynamics approaching the filler surface causes the change in the glass transition. We also find that while the bulk structure of the polymers changes little, the polymers close to the surface tend to be elongated and flattened, independent of the type of interaction we study. Consequently, the dynamics appear strongly influenced by the interactions, while the melt structure is only altered by the geometric constraints imposed by the presence of the filler. Our findings show a strong similarity to those obtained for ultra-thin polymer films (thickness $\lesssim 100$ nm) suggesting that both ultra-thin films and filled-polymer systems might be understood in the same context.

Remarks.
Cryptops mauritianus has been described by Verhoeff (1939) from Mauritius. Subsequent taxonomic revision of Mauritian Cryptops species (Lewis 2002) completed the summary original description and provided additional illustrations of material from near the type locality. In the singular Aldabra specimen examined, the presence of minute accessory spurs on the pretarsus of leg pairs 1–20 (Fig. 3 G) clearly delimits it from all other Cryptops species known from localities in the Western Indian Ocean (Lewis 2011). Subsequent re-description by Lewis (2002) provided data on an immature (“ adolescens ”) specimen which matches the condition of the material presently examined (body length 8 mm), allowing us to confidently refer it to C. mauritianus.

description: A modification of the Gerasimov--Drell--Hearn sum rule suggested by the current experimental data is presented. Within the conventional theoretical framework, we find it necessary to consider the possibility of the presence of a localized region inside a nucleon, in which the electromagnetic (EM) gauge symmetry is spontaneous broken down, if the constraints of the gauge invariance, Lorentz invariance and the assumption of the commutativity of the EM charge density operator at equal-time are considered. We also discuss the propagation of a virtual photon inside a nucleon under such a scenario. A comment on some of the recent model independent works on the same subject is provided.

The impact of non-Gaussianity on the error covariance for observations of the Epoch of Reionization 21-cm power spectrum

description: Recent simulations show the Epoch of Reionization (EoR) 21-cm signal to be inherently non-Gaussian whereby the error covariance matrix $\mathbf{C}_{ij}$ of the 21-cm power spectrum (PS) contains a trispectrum contribution that would be absent if the signal were Gaussian. Using the binned power spectrum and trispectrum from simulations, here we present a methodology for incorporating these with the baseline distribution and system noise to make error predictions for observations with any radio-interferometric array. Here we consider the upcoming SKA-Low. Non-Gaussianity enhances the errors introducing a positive deviation $Δ$ relative to the Gaussian predictions. $Δ$ increases with observation time $t_{\rm obs}$ and saturates as the errors approach the cosmic variance. Considering $t_{\rm obs}=1024$ hours where a $5 σ$ detection is possible at all redshifts $7 \le z \le 13$, in the absence of foregrounds we find that the deviations are important at small $k$ where we have $Δ\sim 40-100 \%$ at $k~\sim 0.04 ~{\rm Mpc}^{-1}$ for some of the redshifts and also at intermediate $k \, (\sim 0.4 ~{\rm Mpc}^{-1})$ where we have $Δ\sim 200 \%$ at $z=7$. Non-Gaussianity also introduces correlations between the errors in different $k$ bins, and we find both correlations and anticorrelations with the correlation coefficient value spanning $-0.4 \le r_{ij} \le 0.8$. Incorporating the foreground wedge, $Δ$ continues to be important ($> 50\%$) at $z=7$. We conclude that non-Gaussianity makes a significant contribution to the errors and this is important in the context of the future instruments that aim to achieve high-sensitivity measurements of the EoR 21-cm PS.

description: Base4NFDI proposal for the initialisation phase of DALIA4NFDI

 

Name of proposed Basic Service: DALIA Platform for Data Literacy Education and Training Resources

 

Abstract:

DALIA4NFDI aims to establish a centralised platform for promoting data literacy and research data management (RDM) through quality-assured, open, accessible teaching and training resources. It emphasises user-centric development by integrating feedback from community workshops, aligning materials with career levels, disciplines, and FAIR data principles.The platform utilises semantic web technology and a knowledge graph for efficient resource organisation and personalised recommendations. DALIA's technical readiness spans several components, including search functionality (TRL 7) and learning paths (TRL 2). The project leverages the DALIA Interchange Format for metadata standardisation, ensuring interoperability with NFDI knowledge graphs and other services. Key objectives during the initialisation phase include empowering the community, enhancing semantic integration within NFDI, and connecting with other platforms like EOSC. By supporting open collaboration, DALIA4NFDI aligns with the NFDI’s goal of harmonising educational efforts across disciplines. Future development focuses on improving features, expanding connections, and ensuring sustainable operations. Through DALIA4NFDI, we envision a robust foundation for fostering data literacy across academia and beyond.

description: In a recent Letter (K.Halpern and K.Huang, Phys. Rev. Lett. 74 (1995) 3526), certain properties of the Local Potential Approximation (LPA) to the Wilson renormalization group were uncovered, which led the authors to conclude that $D>2$ dimensional scalar field theories endowed with {\sl non-polynomial} interactions allow for a continuum of renormalization group fixed points, and that around the Gaussian fixed point, asymptotically free interactions exist. If true, this could herald very important new physics, particularly for the Higgs sector of the Standard Model. Continuing work in support of these ideas, has motivated us to point out that we previously studied the same properties and showed that they lead to very different conclusions. Indeed, in as much as the statements in hep-th/9406199 are correct, they point to some deep and beautiful facts about the LPA and its generalisations, but however no new physics.

When $A$ is a subset of $\mathbb{F}_p\smallsetminus\{0\}$ of cardinality $|A|> (p+1)/3$, then an application of Cauchy-Davenport Theorem gives $\mathbb{F}_p\smallsetminus\{0\}\subset A(A+A)$. In this note, we improve on this and we show that if $|A|\ge 0.3051 p$ implies $A(A+A)\supseteq\mathbb{F}_p\smallsetminus\{0\}$. In the opposite direction we show that there exists a set $A$ such that $|A| > (1/8+o(1))p$ and $\mathbb{F}_p\smallsetminus\{0\}\not\subseteq A(A+A)$.

description: Abstract
This article aims to examine solid waste management practices in Dilla town, Southern Ethiopia. The
empirical data is gathered through repeated fieldwork carried out in 2017 with 120 households in Dilla
town. Observation, questionnaires, interviews, and focus group discussions were used to obtain the primary data. This study has also benefited from various secondary sources. As the study shows, in Dilla, there is a paucity of basic infrastructure to collect and safely dispose solid wastes. As a result, scenes of scattered wastes, the heap of wastes, and overflowing containers are common in the town. These problems are linked to lack of containers, improper use of transfer stations, limited municipal waste collection service, apathy towards environmental sanitation, a gap in law enforcement, low municipal budgets for the sector, and lack of strategic planning. Thus, the existing rules and regulations of solid waste management have to be strengthened and enforced. There have to be mechanisms by which the government and private sectors work together to ensure sustainable solid waste management.

The GENNOVATE approach (“Enabling Gender Equality in Agricultural and Environmental Innovation”) weaves together three broad methodological challenges—context, comparison, and collaboration—and highlights how addressing the social context of innovation contributes to applied research. We discuss GENNOVATE’s analytic approach, sampling framework, data collection, and analysis procedures, and reflect critically on the research strategies adopted to document and learn from the perspectives and experiences of over 7,000 women and men in 137 villages across 26 low- and middle-income countries.
Zero frequency divergence and gauge phase factor in the optical response theory

description: The static current-current correlation leads to the definitional zero frequency divergence (ZFD) in the optical susceptibilities. Previous computations have shown nonequivalent results between two gauges (${\bf p\cdot A}$ and ${\bf E \cdot r}$) under the exact same unperturbed wave functions. We reveal that those problems are caused by the improper treatment of the time-dependent gauge phase factor in the optical response theory. The gauge phase factor, which is conventionally ignored by the theory, is important in solving ZFD and obtaining the equivalent results between these two gauges. The Hamiltonians with these two gauges are not necessary equivalent unless the gauge phase factor is properly considered in the wavefunctions. Both Su-Shrieffer-Heeger (SSH) and Takayama-Lin-Liu-Maki (TLM) models of trans-polyacetylene serve as our illustrative examples to study the linear susceptibility $χ^{(1)}$ through both current-current and dipole-dipole correlations. Previous improper results of the $χ^{(1)}$ calculations and distribution functions with both gauges are discussed. The importance of gauge phase factor to solve the ZFD problem is emphasized based on SSH and TLM models. As a conclusion, the reason why dipole-dipole correlation favors over current-current correlation in the practical computations is explained.

description: Relations between the thermodynamics and dynamics of supercooled liquids approaching a glass transition have been proposed over many years. The potential energy surface of model liquids has been increasingly studied since it provides a connection between the configurational component of the partition function on one hand, and the system dynamics on the other. This connection is most obvious at low temperatures, where the motion of the system can be partitioned into vibrations within a basin of attraction and infrequent inter-basin transitions. In this work, we present a description of the potential energy surface properties of supercooled liquid water. The dynamics of this model has been studied in great details in the last years. Specifically, we locate the minima sampled by the liquid by ``quenches'' from equilibrium configurations generated via molecular dynamics simulations. We calculate the temperature and density dependence of the basin energy, degeneracy, and shape. The temperature dependence of the energy of the minima is qualitatively similar to simple liquids, but has anomalous density dependence. The unusual density dependence is also reflected in the configurational entropy, the thermodynamic measure of degeneracy. Finally, we study the structure of simulated water at the minima, which provides insight on the progressive tetrahedral ordering of the liquid on cooling.
