description: We consider four-dimensional Einstein gravity minimally coupled to a dilaton scalar field with a supergravity-inspired scalar potential. We obtain an exact time-dependent spherically symmetric solution describing gravitational collapse to a static scalar-hairy black hole. The solution can be asymptotically AdS, flat or dS depending on the value of the cosmological constant parameter $Λ$ in the potential. As the advanced time $u$ increases, the spacetime reaches equilibrium in an exponential fashion, i.e., $e^{-u/u_0}$ with $u_0\sim1/(α^4 M_0)^{1/3}$, where $M_0$ is the mass of the final black hole and $α$ is the second parameter in the potential. Similar to the Vaidya solution, at $u=0$, the spacetime can be matched to an (A)dS or flat vacuum except that at the origin a naked singularity may occur. Moreover, a limiting case of our solution with $α=0$ gives rise to an (A)dS generalization of the Roberts solution, thereby making it relevant to critical phenomena. Our results provide a new model for investigating formation of real life black holes with $Λ\geq 0$. For $Λ<0$, it can be instead used to study non-equilibrium thermalization of certain strongly-coupled field theory.

title: Application of ECO2FUME® phosphine fumigant for the complete control of major stored product insect pests in milled rice in Thailand

description: ECO2FUME® phosphine fumigant was used to fumigate milled rice in a commercial plastic bag (5 kg) and milled rice in a jumbo bag (1,000 kg) under gas-proof sheets to assess its performance against a mixed-age culture of Sitophilus zeamais, Tribolium castaneum and Oryzaephilus surinamensis. The trials were divided into 2 groups:
1) milled rice in a commercial plastic bag (packed rice) treated with a 50 g/m3 ECO2FUME® application rate (700 ppm phosphine) for 2 days with two bag stacks of 46 m3 and 55 m3 and for 3 days with two bag stacks of 50 m3 each; and
2) milled rice in a jumbo bag (raw material rice) with stack size of 314 m3 treated with a 35 g/m3 ECO2FUME® application rate (500 ppm phosphine) for 3 days and a stack size of 435 m3 treated with 50 g/m3 ECO2FUME® application rate for 2 days.
Gas sampling lines were installed in the stack to measure the phosphine concentrations during the fumigation period. The results of the fumigation trials showed that mixed-age cultures of the three insect species in packed rice stacks were completely controlled at 2 and 3 days when applied with an ECO2FUME® application rate of 50 g/m3, whereas most insects in untreated control cages remained alive. ECO2FUME® was also 100% effective in raw material rice stacks with complete control of mixed-age cultures of the three insect species using 35 g/m3 of ECO2FUME® for 3 days and 50 g/m3 of ECO2FUME® for 2 days. Commercial tarp fumigation of milled rice with ECO2FUME® can be fumigated successfully without “top up” with good sealing procedures. Gas monitoring at regular intervals throughout the whole fumigation period is part of best fumigation practice to ensure that the minimum recommended phosphine concentration is maintained for complete control of all stages of target insect pests.

description: The uniaxial stress dependence of the band structure and the exciton-polariton transitions in wurtzite ZnO is thoroughly studied using modern first-principles calculations based on the HSE+G0W0 approach, k p modeling using the deformation potential framework, and polarized photoluminescence measurements. The ordering of the valence bands [A(G7), B(G9), C(G7)] is found to be robust even for high uniaxial and biaxial strains. Theoretical results for the uniaxial pressure coefficients and splitting rates of the A, B, and C valence bands and their optical transitions are obtained including the effects of the spin-orbit interaction. The excitonic deformation potentials are derived and the stress rates for hydrostatic pressure are determined based on the results for uniaxial and biaxial stress. In addition, the theory for the stress dependence of the exchange interaction and longitudinal-transversal splitting of the exciton-polaritons is developed using the basic exciton functions of the quasi-cubic approximation and taking the interaction between all exciton states into account. It is shown that the consideration of these effects is crucial for an accurate description of the stress dependence of the optical spectra in ZnO. The theoretical results are compared to polarized photoluminescence measurements of different ZnO substrates as function of uniaxial pressure and experimental values reported in the literature demonstrating an excellent agreement with the computed pressure coefficients.

title: Residual behaviour of phosphine in different commodities

description: Phosphine is one of the most common active substances used in storage protection worldwide. As it is very efficient amongst a broad range of living organisms, it has become the favoured product after phasing out methyl bromide in 2010, as it can be used in many commodities. In 2005, the regulation 396/2005 was enacted and came into force in 2008. With this, the European commission started to evaluate residues arising from the use of a pesticide and to set maximum residue levels (MRLs) for safe and regulated food trade. To proof residue levels are below MRL and therefore far below concerning concentrations of phosphine in food or feed, residue studies are permanently conducted. In addition to support MRL settings, the intention of these trials is to determine withholding periods needed in storage protection, corresponding to PHI (pre harvest interval) for field and glasshouse treatments. Results of those studies show different levels and differences in decrease of residues after defined time periods. Thus, withholding periods for various commodities can differ. Residue trials with repeated exposure were conducted as well to determine possible additive effects.

description: We have investigated spin dynamics in a 2D quantum gas. Through spin-changing collisions, two clouds with opposite spin orientations are spontaneously created in a Bose-Einstein condensate. After ballistic expansion, both clouds acquire ring-shaped density distributions with superimposed angular density modulations. The density distributions depend on the applied magnetic field and are well explained by a simple Bogoliubov model. We show that the two clouds are anti-correlated in momentum space. The observed momentum correlations pave the way towards the creation of an atom source with non-local Einstein-Podolsky-Rosen entanglement.

description: Stored product beetles that are resistant to the fumigant phosphine (hydrogen phosphide) have been reported for more than 50 years in many places worldwide. The high levels of phosphine resistance in lesser grain borer Rhyzopertha dominica (F.) have been noted from several countries including Bangladesh. This study was designed to evaluate the status of resistance to phosphine in Bangladeshi R. dominica and to verify the possible comparison among other phosphine resistant strains from tropical countries viz. Burkina Faso and Malaysia. The data reported and summarized here showed varied levels of resistance compared to the laboratory phosphine susceptible strain (RDLAB). Rhyzopertha dominica strains originating from Bangladesh (RDBGD) and Burkina Faso (RDBKF) exhibited higher levels of resistance to phosphine compared to the Malaysian strains (RDMAL). Analysis of dose–response data indicated that the RDBGD and RDBKF strains were the most resistant to phosphine under different exposure periods. At LC50, these two strains were more than 80-fold more resistant at all exposures compared to the susceptible strain. Results also revealed that RDBGD and RDBKF strains required a relatively high concentration of 334.94 and 240.081 mg L-1 for 99% mortality. The mean survival time (MST) for the phosphine resistant and susceptible also varied significantly. The maximum MST was recorded for RDBGD and RDBKF strains. The present findings further confirmed that the Bangladeshi originated R. dominica strain contained higher resistance to phosphine compared to strains from other countries. This study could be useful in developing management strategies to prevent stored grain from being infested by resistant strains of R. dominica in tropical countries.

description: We study the finite-temperature transition in a model XY antiferromagnet on a pyrochlore lattice, which describes the pyrochlore material Er2Ti2O7. The ordered magnetic structure selected by thermal fluctuations is six-fold degenerate. Nevertheless, our classical Monte Carlo simulations show that the critical behavior corresponds to the three-dimensional XY universality class. We determine an additional critical exponent nu_6=0.75>nu characteristic of a dangerously irrelevant scaling variable. Persistent thermal fluctuations in the ordered phase are revealed in Monte Carlo simulations by the peculiar coexistence of Bragg peaks and diffuse magnetic scattering, the feature also observed in neutron diffraction experiments.

Prominente Beispiele sind die APOS-Theorie (Dubinsky, 1991), der Procept-Ansatz (Gray & Tall, 1994) oder das Modell nach Sfard (1991, 1992). In diesen Theorien werden mathematische Begriffe als Prozess-Objekt-Dualitäten aufgefasst, sodass ein mathematischer Begriff als mentaler mathematischer Prozess oder als mentales mathematisches Objekt verstanden werden kann. Hierbei wird angenommen, dass in dem Erwerbsprozess eines Begriffs das Objekt aus dem jeweiligen Prozess hervorgeht, also für ein Begriffsverständnis insbesondere das Prozesswissen vor dem Objektwissen erworben werden sollte. Pantziara und Philippou (2012) lieferten bereits empirische Evidenz, die darauf hindeutet, dass sich bei dem Bruchzahlbegriff eine Progression vom Prozess- zum Objektwissen zeigt.

description: Sub-lethal dose application of phosphine (PH3) that is mostly caused by leakage during fumigation has resulted in resistance in Tribolium castaneum, Rhyzopertha dominica, Cryptolestes ferrugineus, Sitophilus oryzae, and other stored-product insect pest species worldwide. However, PH3 resistance in the saw-toothed grain beetle, Oryzaephilus surinamensis, has not been reported in any country. Additionally, the discriminating dose of PH3 for eggs of O. surinamensis has not been estimated. In this study, the discriminating dose for eggs of the susceptible strain of O. surinamensis was estimated as 28.4 ppm applied for 3 d. Adults from 4 out of 14 field-collected populations showed detectable resistance to PH3 whereas eggs in 9 out of 14 populations had detectable resistance. Resistance frequencies in both adults and eggs in Box BF, Box BR and OKWat populations were > 90%. Levels of resistance (LC99) in these three populations were estimated using probit analysis. LC99 values for adults of Box BF, Box BR, and OKWat populations were 320.5, 290.7 and 263 ppm, respectively, whereas those in eggs from the same populations were 1055.9, 1030.7, and 564.5 ppm, respectively, over 3-d fumigation. Resistance levels of adults and eggs of the most resistant population, Box BF, were 24.3- and 43.6-fold, respectively, higher than those of the lab-susceptible strain. The resistance levels in eggs from these three populations were > 3-fold higher than that in adults and this shows eggs of O. surinamensis are more tolerant to PH3 than adults. These results indicate that it may not be practical to use PH3 to control Box BF and Box BR populations. Therefore, it is important to develop alternative pest management strategies for controlling highly PH3-resistant populations of stored-product insect pests.

Basiswissen entspricht dem Wissen über zentrale Definitionen und Zusammenhänge; es umfasst dabei Wissen um den Begriffsinhalt, den Begriffsumfang und das Begriffsnetz (Weigand et al., 2014). Methodenwissen umfasst Wissen über den korrekten Aufbau von Beweisen, insbesondere Wissen über Beweisschema, Beweisstruktur und Beweiskette (Heinze & Reiss, 2003).

description: Recent implications of results from quantum information theory applied to black holes has led to the confusing conclusions that requires either abandoning the equivalence principle (e.g. the firewall picture), or the no-hair theorem (e.g. the fuzzball picture), or even more unpalatable options. The recent discovery of a pulsar orbiting a black hole opens up new possibilities for tests of theories of gravity. We examine possible observational effects of semiclassical quantum gravity in the vicinity of black holes, as probed by pulsars and event horizon telescope imaging of flares. Pulsar radiation is observable at wavelengths only two orders of magnitude shorter than the Hawking radiation, so precision interferometry of lensed pulsar images may shed light on the quantum gravitational processes and interaction of Hawking radiation with the spacetime near the black hole. This paper discusses the impact on the pulsar radiation interference pattern, which is observable through the modulation index in the foreseeable future, and discusses a possible classical limit of BHC.

description: We consider one cosmological application of an axionic extension of the Maxwell-Vlasov theory, which describes axionically induced oscillatory regime in the state of global magnetic field evolving in the anisotropic expanding (early) universe. We show that the cooperative electric field in the relativistic plasma, being coupled to the pseudoscalar (axion) and global magnetic fields, plays the role of a regulator in this three-level system; in particular, the cooperative (Vlasov) electric field converts the regime of anomalous growth of the pseudoscalar field, caused by the axion-photon coupling at the inflationary epoch of the universe expansion, into an oscillatory regime with finite density of relic axions. We analyze solutions to the dispersion equations for the axionically induced cooperative oscillations of the electric field in the relativistic plasma.

Entsprechend stellen sie in der mathematischen Ausbildung ein wichtiges Lernziel dar (Reiss & Ufer, 2009), was bspw. durch die Einbettung in die Bildungsstandards deutlich wird (vgl. KMK, 2003). Empirische Untersuchungen haben jedoch wiederholt in verschiedenen Jahrgängen und Kontexten gezeigt, dass Lernende Schwierigkeiten mit mathematischen Beweisen haben (Healy & Hoyles, 1998; Heinze, 2004). Diese Schwierigkeiten lassen sich u.a. durch unzureichendes Wissen über Beweise (aufgefasst als Objekte) und den Umgang mit Beweisen (aufgefasst als Prozesse wie bspw. das Konstruieren oder Validieren) erklären (Heinze & Reiss, 2003). Entsprechendes Wissen über Beweise und den Umgang mit Beweisen kann wiederum als ein Aspekt individuellen Beweisverständnisses beschrieben werden (Sporn et al., 2021).

description: Numa sociedade que desconsidera e ignora o corpo dos processos existenciais, é precioso saber que há um espaço na psicologia para lembrar que o corpo tem uma linguagem que precisa ser vista, escutada e compreendida, no mínimo. Esse chamamento veio de Wilhelm Reich (1897-1957), que unindo ousadia, inteligência e coragem, no decorrer da sua prática profissional, comunicou o quanto este corpo guarda memórias, emoções e marcas significativas, construídas ao longo do desenvolvimento, com todos os estresses e as delícias de uma vida. Essas marcas ficaram conhecidas como couraças musculares, que contém afetos, emoções, recordações e energia estagnada. Considerando que as couraças musculares podem ser flexibilizadas por meio de movimentos, a proposta do presente trabalho é discutir as possibilidades que a dança traz, enquanto complemento do trabalho da Análise Reichiana, como também enquanto facilitadora de flexibilizações psíquicas e musculares.

description: Short gamma-ray bursts (sGRBs) are widely believed to result from the mergers of compact binaries. This model predicts an afterglow that bears the characteristic signatures of a constant, low density medium, including a smooth prompt-afterglow transition, and a simple temporal evolution. However, these expectations are in conflict with observations for a non-negligible fraction of sGRB afterglows. In particular, the onset of the afterglow phase for some of these events appears to be delayed and, in addition, a few of them exhibit late- time rapid fading in their lightcurves. We show that these peculiar observations can be explained independently of ongoing central engine activity if some sGRB progenitors are compact binaries hosting at least one pulsar. The Poynting flux emanating from the pulsar companion can excavate a bow-shock cavity surround- ing the binary. If this cavity is larger than the shock deceleration length scale in the undisturbed interstellar medium, then the onset of the afterglow will be delayed. Should the deceleration occur entirely within the swept-up thin shell, a rapid fade in the lightcurve will ensue. We identify two types of pulsar that can achieve the conditions necessary for altering the afterglow: low field, long lived pulsars, and high field pulsars. We find that a sizable fraction (~20-50%) of low field pulsars are likely to reside in neutron star binaries based on observations, while their high field counterparts are not. Hydrodynamical calculations motivated by this model are shown to be in good agreement with observations of sGRB afterglow lightcurves.

description: Mathematische Problemlöseaufgaben erfolgreich zu bearbeiten ist eine in den Bildungsstandards des Faches Mathematik verankerte und zu fördernde Kompetenz (KMK, 2003). Unter Problemlöseaufgaben werden jene Aufgaben verstanden, zu deren Bearbeitung geeignete Heurismen zielführend auszuwählen wie auch anzuwenden sind (Bruder & Collet, 2011) und deren Bearbeitung idealtypisch entlang von spezifischen Problemlösephasen erfolgt. Heurismen verstehen sich dabei als Werkzeug und machen eine Bearbeitung überhaupt erst möglich. Jene können in heuristische Hilfsmittel, Strategien und Prinzipien unterschieden werden (Bruder & Collet, 2011).

description: Modified atmosphere hermetic storage, now used in over 115 countries for fumigant-free storage of dry commodities from coffee to rice and maize, has been available for almost three decades. This paper describes the progress in the field use of hermetic postharvest storage systems and of recent innovations in this technology which include the introduction of remote monitoring of temperature, humidity and O2 or CO2 levels in large, sealed hermetic containers. Also, introduced in 2018, is the Cocoon Lite™, a 2nd generation multi-tonne container with major improvements in the permeability, weight and cost of high performance, large hermetic storage systems. Early examples of the uses of these innovations and data obtained from their study is expected by year end. The GrainPro EcoWiSe™ is a remote sensing system that enables monitoring of temperature, moisture and oxygen/carbon dioxide levels, thus providing real-time data on the conditions of the stored commodity involved without manual intervention. One (or more) low-cost, remote, wireless sensors/transmitters placed inside sealed. Postharvest hermetic storage units can be read remotely on laptops or cellphones. Data collected and accumulated over time enables development of an “algorithm” for a stored commodity to define an alarm, where the user can be notified immediately of any unsafe humidity or oxygen storage conditions. A substantial advance in large hermetic storage containers known as Cocoons™ is the new Cocoon Lite, a 500:1 improvement in permeability to oxygen as well as a unit weight only 28% of existing Cocoons with the same capacity and a significantly lower cost. The paper also discusses prevention of the public health hazard of exponential growth of aflatoxin levels in conventional postharvest storage such as in rice, maize, and groundnuts; field data is provided on the control achieved through hermetic storage.

description: While clinical education-related stressors in other healthcare professions have been reported, clinical education stressors in physical therapy students are not yet clear. This study aimed to identify clusters of stressors associated with clinical education among Japanese physical therapy students and determine the association between these clusters and emotional states. Participants were physical therapy students who had completed five weeks of clinical education. In addition to demographic data, the survey included the Brief Job Stress Questionnaire (BJSQ) and the Stress Reaction Scale (SRS-18). Exploratory factor analysis was used to extract latent variables for sub-items of the BJSQ. Spearman’s correlation coefficients between the extracted latent variables and the subscales of the SRS-18 were calculated. Data from 114 individuals (median age 21 years, 68 men and 46 women) were analyzed. The variables identified as clusters of stressors were: 1) “adaptation to clinical education”; 2) “task burden”; and 3) “appropriate work environment.” These three clusters of stressors were significantly but only weakly correlated with the subscales of the SRS-18 (|rs| ≤ |-.39|). The stressors associated with physical therapy clinical education need to be understood in terms of the students’ active attitude toward clinical education, the burden of practice tasks, and the physical environment during practice.

description: To examine the insulating mechanism of 5$d$ transition metal oxide Sr$_2$IrO$_4$, we study the ground state properties of a three-orbital Hubbard model with a large relativistic spin-orbit coupling on a square lattice. Using a variational Monte Carlo method, we find that the insulating state appearing in the ground state phase diagram for one hole per site varies from a weakly correlated to a strongly correlated antiferromagnetic (AF) state with increasing Coulomb interactions. This crossover is characterized by the different energy gain mechanisms of the AF insulating state, i.e., from an interaction-energy driven Slater-type insulator to a band-energy driven Mott-type insulator with increasing Coulomb interactions. Our calculations reveal that Sr$_2$IrO$_4$ is a "moderately correlated" AF insulator located in the intermediate coupling region between a Slater-type and a Mott-type insulators.

description: Darstellungsvernetzung kann den Aufbau konzeptuellen Verständnisses unterstützen (Duval, 2006). Unterrichten mit Darstellungsvernetzung ist jedoch bisher relativ wenig untersucht worden (Stylianou, 2010). Das hier vorgestellte Projekt trägt dazu bei, genauer zu untersuchen, wie Lehrkräfte Darstellungsvernetzung im Unterrichtsgespräch etablieren. Im hier vorgestellten Projekt werden am Beispiel von bedingten Wahrscheinlichkeiten Praktiken von Lehrkräften rekonstruiert, um herauszufinden, welche Aktionen oder Impulse Darstellungsvernetzungsprozesse fördern.

description: Die Heterogenität bei Studienanfänger*innen im Lehramt Mathematik ist groß und das Führen und Erklären von Beweisen arithmetischer Zusammenhänge sowie die Entwicklung inhaltlich-anschaulicher Darstellungen führt regelmäßig zu Schwierigkeiten (Kempen, 2019). Erklärungen nehmen eine zentrale Rolle im Mathematikunterricht ein. Sie haben als eine Wissens- oder Fähigkeitsvermittlung das Ziel, dass jemand etwas weiß, versteht oder kann (Vogt, 2009). Das Lehramtsstudium schafft für die angehenden Lehrkräfte eine fachmathematische und -didaktische Wissensgrundlage, auf deren Basis Erklärungen formuliert werden können (Schmidt-Thieme, 2014).

description: Grundvorstellungen als normativ formulierte inhaltliche Deutungen mathematischer Begriffe sind in den letzten beiden Jahrzehnten zentral für die Unterrichtsplanung im Fach Mathematik geworden (Greefrath et al., 2016; Salle & Clüver, 2021; vom Hofe, 1995). Durch Lehr-Lern-Arrangements, in denen die inhaltlichen Deutungen zum Tragen kommen, soll den Lernenden neben einer Sinnkonstituierung der mathematischen Begriffe ermöglicht werden, mental mit diesen Begriffen zu operieren und sie flexibel anzuwenden (vom Hofe, 1995). Welche individuellen Vorstellungen Schüler*innen in diesem Zuge aufbauen, wird unter dem sogenannten deskriptiven Aspekt der Grundvorstellungstheorie diskutiert (vom Hofe, 1995).
Amplitude death in coupled robust-chaos oscillators

description: We investigate the synchronization behavior of a system of globally coupled, continuous-time oscillators possessing robust chaos. The local dynamics corresponds to the Shimizu-Morioka model where the occurrence of robust chaos in a region of its parameter space has been recently discovered. We show that the global coupling can drive the oscillators to synchronization into a fixed point created by the coupling, resulting in amplitude death in the system. The existence of robust chaos allows to introduce heterogeneity in the local parameters, while guaranteeing the functioning of all the oscillators in a chaotic mode. In this case, the system reaches a state of oscillation death, with coexisting clusters of oscillators in different steady states. The phenomena of amplitude death or oscillation death in coupled robust-chaos flows could be employed as mechanisms for stabilization and control in systems that require reliable operation under chaos.
