description: In this work we investigate the global activity patterns predicted from a model active region heated by distributions of nanoflares that have a range of frequencies. What differs is the average frequency of the distributions. The activity patterns are manifested in time lag maps of narrow-band instrument channel pairs. We combine hydrodynamic and forward modeling codes with a magnetic field extrapolation to create a model active region and apply the time lag method to synthetic observations. Our aim is not to reproduce a particular set of observations in detail, but to recover some typical properties and patterns observed in active regions. Our key findings are the following. 1. cooling dominates the time lag signature and the time lags between the channel pairs are generally consistent with observed values. 2. shorter coronal loops in the core cool more quickly than longer loops at the periphery. 3. all channel pairs show zero time lag when the line-of-sight passes through coronal loop foot-points. 4. there is strong evidence that plasma must be re-energized on a time scale comparable to the cooling timescale to reproduce the observed coronal activity, but it is likely that a relatively broad spectrum of heating frequencies are operating across active regions. 5. due to their highly dynamic nature, we find nanoflare trains produce zero time lags along entire flux tubes in our model active region that are seen between the same channel pairs in observed active regions.

description: Die Friedliche Revolution und die folgende Systemtransformation wurden von den Ostdeutschen als tiefer biographischer Einschnitt erlebt. Weite Teile ihrer Lebenswelt veränderten sich, einstige Sicherheiten waren auf einmal nicht mehr sicher. Dieser revolutionäre Wandlungsprozess wurde ganz unterschiedlich erlebt und gedeutet. Heute prägen die damaligen Erfahrungen den Rückblick auf diese Zeit. Es besteht ein Erinnerungskonflikt zwischen einem Revolutionsgedächtnis, das die demokratischen Errungenschaften hochhält, und einem Verlustgedächtnis, das den Umbruch als Zeit der Verunsicherung und enttäuschten Erwartungen abgespeichert hat und bis heute eine skeptische Haltung zur neuen politischen Ordnung einnimmt. Eng verklammert ist die jeweilige Deutung zudem mit unterschiedlichen Geschichtsbildern von der SED-Diktatur, deren wichtigste Quelle heute die Familie ist. Schule und Gedenkstätten spielen bei der Ausprägung von Geschichtsbildern hingegen eine deutlich nachgeordnete Rolle. Auch die jeweiligen Diktaturerfahrungen prägen also die Sicht auf die Transformation.

description: In anticipation of new observational results for Jupiter's axial moment of inertia and gravitational zonal harmonic coefficients from the forthcoming Juno orbiter, we present a number of preliminary Jupiter interior models. We combine results from ab initio computer simulations of hydrogen-helium mixtures, including immiscibility calculations, with a new nonperturbative calculation of Jupiter's zonal harmonic coefficients, to derive a self-consistent model for the planet's external gravity and moment of inertia. We assume helium rain modified the interior temperature and composition profiles. Our calculation predicts zonal harmonic values to which measurements can be compared. Although some models fit the observed (pre-Juno) second- and fourth-order zonal harmonics to within their error bars, our preferred reference model predicts a fourth-order zonal harmonic whose absolute value lies above the pre-Juno error bars. This model has a dense core of about 12 Earth masses, and a hydrogen-helium-rich envelope with approximately 3 times solar metallicity.

description: We revisit the derivation of the Hawking-Moss transition rate. Using the static coordinates, we show that the Euclidean action is entirely determined by the contribution of the entropy of de Sitter space which is proportional to the surface area of the horizon. This holographic feature is common to any static spacetime with a horizon on which the shift vector vanishes.

description: In high energy heavy ion collisions, the directed flow of particles is conventionally measured with respect to that of the projectile spectators, which is defined as positive $x$ direction. But it is not known if the spectators deflect in the "outward" direction or "inward" -- toward the center line of the collision. In this Letter we discuss how the measurements of the directed flow at mid-rapidity, especially in asymmetric collision such as Cu+Au, can be used to answer this question. We show that the existing data strongly favor the case that the spectators, in the ultrarelativistic collisions, on average deflect outwards.

High-efficiency diphenylsulfon derivatives-based organic light-emitting diode exhibiting thermally activated delayed fluorescence

description: Novel thermally activated delayed fluorescence (TADF) material with diphenyl sulfone (DPS) as an electron acceptor and 3,6-dimethoxycarbazole (DMOC) and 1,3,6,8-Tetramethyl-9H-carbazole (TMC) as electron donors were investigated theoretically for a blue organic light emitting diode (OLED) emitter. We calculate the energies of the first singlet (S1) and first triplet (T1)-excited states of TADF materials by performing density functional theory (DFT) and time-dependent DFT (TD-DFT) calculations on the ground state using a dependence on charge transfer amounts for the optimal Hartree-Fock percentage in the exchange-correlation of TD-DFT. The calculated ΔEST values of TMC-DPS (0.094 eV) was smaller than DMOC-DPS (0.386 eV) because of the large dihedral angles between the donor and accepter moieties. We show that TMC-DPS would have a suitable blue OLED emitter, because it has a large dihedral angle that creates a small spatial overlap between the HOMO and the LUMO and, consequently, the small ΔEST and the emission wavelength of 2.82 eV (439.9 nm).

Chromospheric Nanoflares as a Source of Coronal Plasma: II. Repeating Nanoflares

description: The million degree plasma of the solar corona must be supplied by the underlying layers of the atmosphere. The mechanism and location of energy release, and the precise source of coronal plasma, remain unresolved. In earlier work we pursued the idea that warm plasma is supplied to the corona via direct heating of the chromosphere by nanoflares, contrary to the prevailing belief that the corona is heated in-situ and the chromosphere is subsequently energized and ablated by thermal conduction. We found that single (low-frequency) chromospheric nanoflares could not explain the observed intensities, Doppler-shifts, and red/blue asymmetries in Fe XII and XIV emission lines. In the present work we follow up on another suggestion that the corona could be powered by chromospheric nanoflares that repeat on a timescale substantially shorter than the cooling/draining timescale. That is, a single magnetic strand is re-supplied with coronal plasma before the existing plasma has time to cool and drain. We perform a series of hydrodynamic experiments and predict the Fe XII and XIV line intensities, Doppler-shifts, and red/blue asymmetries. We find that our predicted quantities disagree dramatically with observations and fully developed loop structures cannot be created by intermediate- or high-frequency chromospheric nanoflares. We conclude that the mechanism ultimately responsible for producing coronal plasma operates above the chromosphere, but this does not preclude the possibility of a similar mechanism powering the chromosphere; extreme examples of which may be responsible for heating chromospheric plasma to transition region temperatures (e.g. type II spicules).

description: Es ist etwas in Bewegung geraten in der ohnehin komplizierten deutsch-deutschen Erinnerungslandschaft. Nach dreißig Jahren wandeln sich die Rückblicke auf die jüngste Vergangenheit. Im Fokus steht dabei die Zeitenwende von 1989/90, die Deutschland und Europa wieder intensiv umtreibt. Eine neue Welle von Populismen und Nationalismen spült scheinbar vergessene, verdrängte oder überwunden geglaubte Fragen zu den materiellen wie ideellen Erbschaften von Staats- und Postsozialismus erneut an die Oberflächen. Als zuletzt auch die sonst in dieser Hinsicht so schweigsame Bundeskanzlerin Angela Merkel in einem Interview gegenwärtig – angesichts bisweilen heftiger publizistischer Debatten – ein ostdeutsches „1968“ aufdämmern sah, wurde offensichtlich: Vormals festgefügte Meister- beziehungsweise Siegererzählungen (West?) und hierauf bezogene Gegen- beziehungsweise Opfererzählungen (Ost?) werden brüchig und verlieren an Überzeugungs- und Bindekraft.Politische, generationelle, wissenschaftliche und kommunikativ-technologische Dynamiken überschneiden sich in einem nur schwer überschaubaren Geflecht aus vielfältigen Interessen, Meinungen und Emotionen. Und mittendrin: eine gerade erst dieses neue Feld empirisch für sich entdeckende Zeitgeschichtsforschung.

description: We construct infinite new classes of $AdS_4\times S^1\times S^5$ solutions of type IIB string theory which have non-trivial $SL(2,\mathbb{Z})$ monodromy along the $S^1$ direction. The solutions are supersymmetric and holographically dual, generically, to $\mathcal{N}=1$ SCFTs in $d=3$. The solutions are first constructed as $AdS_4\times \mathbb{R}$ solutions in $D=5$ $SO(6)$ gauged supergravity and then uplifted to $D=10$. Unlike the known $AdS_4\times \mathbb{R}$ S-fold solutions, there is no continuous symmetry associated with the $\mathbb{R}$ direction. The solutions all arise as limiting cases of Janus solutions of $d=4$, $\mathcal{N}=4$ SYM theory which are supported both by a different value of the coupling constant on either side of the interface, as well as by fermion and boson mass deformations. As special cases, the construction recovers three known S-fold constructions, preserving $\mathcal{N}=1,2$ and 4 supersymmetry, as well as a recently constructed $\mathcal{N}=1$ $AdS_4\times S^1\times S^5$ solution (not S-folded). We also present some novel "one-sided Janus" solutions that are non-singular.

description: The article explores the Apostle Paul’s method of preaching, particularly his use of his personal conversion and experience with divine grace as a recurring theme. It argues that Paul’s “one sermon” acts as spiritual nuclear fission, generating unending spiritual energy for fulfilling his ministry. Drawing parallels with Rabbi Abraham Joshua Heschel’s notion of divine wonder and the transformative power of the cross, the article contends that preachers should root their ministries in their personal encounters with the living God. Doing so not only energizes their work but also leads to spontaneous doxological combustion—a sudden, organic burst into praise and worship. The article concludes that this authentic approach to ministry can transform both the minister and the congregation.
Theoretical study of asymmetric A-π-D-π-D-π-A' tribranched organic sensitizer for Dye-sensitized solar cells

description: An asymmetric A-π-D-π-D-π-A' tribranched organic dye (dye1) with a cyanoacrylic acid and an indolinum carboxyl acid as electron acceptors and a triphenylamine as an electron donor was designed and theoretically investigated for dye-sensitized solar cells (DSSCs). Dye1 was compared to reference well-known dyes with single electron acceptors (D5 and JYL-SQ6). Density functional theory and time-dependent density functional theory calculations were used to estimate the photovoltaic properties of the dyes. Due to the different lowest unoccupied molecular orbital levels of each acceptor and the energy antenna of the dual electron donor (D-π-D), the absorption spectrum of each branch displayed different shapes. Considering the overall properties, the asymmetric A-π-D-π-D-π-A' tribranched organic dye exhibited high conversion efficiency performance for DSSCs. The findings of this work suggest that optimizing the branch of electron donors and acceptors in dye sensitizers based on asymmetric A-π-D-π-D-π-A' tribranched organic dye produces good photovoltaic properties for DSSCs.

description: A new model of nonlinear electrodynamics with a dimensional parameter $β$ coupled to gravity is considered. We show that an accelerated expansion of the universe takes place if the nonlinear electromagnetic field is the source of the gravitational field. A pure magnetic universe is investigated and the magnetic field drives the universe to accelerate. In this model, after the big bang, the universe undergoes inflation, and the accelerated expansion and then decelerates approaching Minkowski spacetime asymptotically. We demonstrate the causality of the model and a classical stability at the deceleration phase.

The transport mean free path is found to stay inversely proportional to the square of the relative fluctuation of the dielectric constant as in the 1D and 2D cases but with . The transport properties of light through a sample with a fixed size can be modulated from ballistic to localized regime as well, and a generalized scaling function is defined to determine the light transport status in such a sample. The calculation of the diffusion coefficient and the energy density profile of the most transmitted eigenchannel clearly exhibits the transition of transport behaviour from diffusion to localization.

However, fundamental understanding of the underlying mechanisms remains elusive. Here we present a new model for multi-shot helicity-dependent AOS in ferromagnetic materials based on a purely heat-driven mechanism in the presence of Magnetic Circular Dichroism (MCD). We predict that AOS should be possible with as little as 0.5% of MCD, after a minimum number of laser shots. Finally, we re- produce previous AOS results by simulating the sweeping of a laser beam on an FePtC granular ferromagnetic film.

description: The concept of homeschooling in the United States, though more mainstream today, remains an alternative way of educating our children. Researchers seeking to examine this method of education often focus on the outcomes for the children who receive their education through this mode of education. Seldom does the attention fall to the educator, the homeschool parent. The mother typically takes the active role in educating the children and she receives little attention as a person (Lois, 2016). This study examines the ways in which these mother/teachers navigate the academic and non-academic parts of their lives and what impact that has on their own and their family’s well-being. Because the number of families who choose this mode of education continues to rise, examining factors that affect their well-being is crucial (Ray, 2022). Nine online discussions with 26 homeschooling mothers set up as focus groups revealed strong connections to self-efficacy and agency. Group sizes ranged from two to four participants making some of the groups dyadic interviews rather than focus groups (Morgan, 1996). Agency and self-efficacy contributed to the sense of well-being for the mother and by extension to her family (Bandura 1977, 2006). The findings from this study suggest other homeschool mothers and past experiences played a role in their self-efficacy that contributed to their well-being leading to their self-efficacy expectation. Though previous literature suggests that homeschooling mothers connect strongly to the concept of good mother, the mothers in this study rejected many of the principles Hays (1996) suggests a good mother exhibits. The use of metaphors as a qualitative tool aided in the discovery of ways these mothers navigate their lives and how their management impacted their families. As an engaged qualitative inductive study, suggestions to existing homeschool groups and organizations that hope to support homeschooling families gave a connection back to communities outside of academia.

description: Saturable absorption is a non-perturbative nonlinear optical phenomenon that plays a pivotal role in the generation of ultrafast light pulses. Here we show that this effect emerges in graphene at unprecedentedly low light intensities, thus opening avenues to new nonlinear physics and applications in optical technology. Specifically, we theoretically investigate saturable absorption in extended graphene by developing a non-perturbative single-particle approach, describing conduction-electron dynamics in the atomically-thin material using the two-dimensional Dirac equation for massless Dirac fermions, which is recast in the form of generalized Bloch equations. By solving the electron dynamics non-perturbatively, we account for both interband and intraband contributions to the intensity-dependent saturated conductivity and conclude that the former dominates regardless of the intrinsic doping state of the material. The results are in excellent agreement with atomistic quantum-mechanical simulations including higher-band effects. Additionally, we find that the modulation depth of saturable absorption in graphene can be electrically manipulated through an externally applied gate voltage. Our results are relevant for the development of graphene-based optoelectronic devices, as well as for applications in mode-locking and random lasers.

description: We investigate the feasibility of CMOS-compatible optical structures to develop novel integrated spectroscopy systems. We show that local field enhancement is achievable utilizing dimers of plasmonic nanospheres that can be assembled from colloidal solutions on top of a CMOS-compatible optical waveguide. The resonant dimer nanoantennas are excited by modes guided in the integrated silicon nitride waveguide. Simulations show that 100 fold electric field enhancement builds up in the dimer gap as compared to the waveguide evanescent field amplitude at the same location. We investigate how the field enhancement depends on dimer location, orientation, distance and excited waveguide modes.

In the ablation casting, the mold is eroded away by water, and the water becomes responsible for the heat transfer from the casting. In our work, ablative cooling could not be applied quickly enough to have any influence on the microstructure of the 1 mm thick cast section. In the 2-mm-thick specimen, ablation increased the nodule count from 497 to 1484 and graphite nodularity from 76 to 93%. In the 8 mm section, the tensile yield strength increased from 539 to 624 MPa and elongation was increased from 4.9 to 10.2%.

description: In [1], Nakatsu and Takasaki have shown that the melting crystal model behind the topological strings vertex provides a tau-function of the KP hierarchy after an appropriate time deformation. We revisit their derivation with a focus on the underlying quantum $W_{1+\infty}$ symmetry. Specifically, we point out the role played by automorphisms and the connection with the intertwiner - or vertex operator - of the algebra. This algebraic perspective allows us to extend part of their derivation to the refined melting crystal model, lifting the algebra to the quantum toroidal algebra of $\mathfrak{gl}(1)$ (also called Ding-Iohara-Miki algebra). In this way, we take a first step toward the definition of deformed hierarchies associated to A-model refined topological strings.

description: We investigate the harmonic response of neon atoms to mid-IR laser fields (2000-3000nm) using a single-active electron (SAE) model and the fully ab initio all-electron R-Matrix with Time-dependence (RMT) method. The laser peak intensity and wavelength are varied to find suitable parameters for high-harmonic imaging in the water window. Comparison of the SAE and RMT results shows qualitative agreement between them as well as parameters such as the cutoff frequency predicted by the classical three-step model. However, there are significant differences in the details, particularly in the predicted conversion efficiency. These details indicate the possible importance of multi-electron effects, as well as a strong sensitivity of quantitative predictions on specific aspects of the numerical model.

description: We compute the top quark contribution to the two-loop amplitude for on-shell $Z$ boson pair production in gluon fusion, $gg \to ZZ$. Exact dependence on the top quark mass is retained. For each phase space point the integral reduction is performed numerically and the master integrals are evaluated using the auxiliary mass flow method, allowing fast computation of the amplitude with very high precision.

description: We study topological defect lines in two character rational conformal field theories. Among them one set of two character theories are commutant pairs in $E_{8,1}$ conformal field theory. Using these defect lines we construct defect partition function in the $E_8$ theory. We find that the defects preserve only a part of the $E_8$ current algebra symmetry. We also determine the defect partition function in $c=24$ CFTs using these defects lines of 2 character theories and we find that, with appropriate choice of commutant pairs, these defects preserve all current algebra symmetries of c = 24 CFTs.

description: We study the observability of new interactions which modify Higgs-pair production via vector-boson fusion processes at the LHC and at future proton-proton colliders. In an effective-Lagrangian approach, we explore in particular the effect of the operator $h^2 W_{μν}^a W^{a,μν}$, which describes the interaction of the Higgs boson with transverse vector-boson polarization modes. By tagging highly boosted Higgs bosons in the final state, we determine projected bounds for the coefficient of this operator at the LHC and at a future 27 TeV or 100 TeV collider. Taking into account unitarity constraints, we estimate the new-physics discovery potential of Higgs pair production in this channel.

description: We investigate the potential stochastic gravitational waves from first-order electroweak phase transitions in a model with pseudo-Nambu-Goldstone dark matter and two Higgs doublets. The dark matter candidate can naturally evade direct detection bounds, and can achieve the observed relic abundance via the thermal mechanism. Three scalar fields in the model obtain vacuum expectation values, related to phase transitions at the early Universe. We search for the parameter points that can cause first-order phase transitions, taking into account the existed experimental constraints. The resulting gravitational wave spectra are further evaluated. Some parameter points are found to induce strong gravitational wave signals, which have the opportunity to be detected in future space-based interferometer experiments LISA, Taiji, and TianQin.

description: In the present article, we study the Hawking effect and the bounds on greybody factor in a spacetime with radial deformation. This deformation is expected to carry the imprint of a non-Einsteinian theory of gravity, but shares some of the important characteristics of general relativity (GR). In particular, this radial deformation will restore the asymptotic behavior, and also allows for the separation of the scalar field equation in terms of the angular and radial coordinates -- making it suitable to study the Hawking effect and greybody factors. However, the radial deformation would introduce a change in the locations of the horizon, and therefore, the temperature of the Hawking effect naturally alters. In fact, we observe that the deformation parameter has an enhancing effect on both temperature and bounds on the greybody factor, which introduces a useful distinction with the Kerr spacetime. We discuss these effects elaborately, and broadly study the thermal behavior of a radially deformed spacetime.

Supergravity solution-generating techniques and canonical transformations of $σ$-models from $O(D,D)$

description: Within the framework of the flux formulation of Double Field Theory (DFT) we employ a generalised Scherk-Schwarz ansatz and discuss the classification of the twists that in the presence of the strong constraint give rise to constant generalised fluxes interpreted as gaugings. We analyse the various possibilities of turning on the fluxes $H_{ijk}, F_{ij}{}^k, Q_i{}^{jk}$ and $R^{ijk}$, and the solutions for the twists allowed in each case. While we do not impose the DFT (or equivalently supergravity) equations of motion, our results provide solution-generating techniques in supergravity when applied to a background that does solve the DFT equations. At the same time, our results give rise also to canonical transformations of 2-dimensional $σ$-models, a fact which is interesting especially because these are integrability-preserving transformations on the worldsheet. Both the solution-generating techniques of supergravity and the canonical transformations of 2-dimensional $σ$-models arise as maps that leave the generalised fluxes of DFT and their flat derivatives invariant. These maps include the known abelian/non-abelian/Poisson-Lie T-duality transformations, Yang-Baxter deformations, as well as novel generalisations of them.

description: This study aimed to investigate the effect of replacing silicon with 4.3% aluminum on the kinetics of the bainitic transformation and its effect on the physical properties of cast iron with a chemical composition of 3.4% C, 4.3% Al, 0.32% Si, 0.04% Mg. First, the samples were prepared to the same dimensions followed by austenitization for 2 hours at 900 °C; Then, austempering was performed on the samples at four temperatures i.e., 375 °C, 400 °C, 425 °C, and 450 °C (high-temperature region) for different periods (1–512 min). Microstructural studies were performed by both optical and electron microscopes and it was found that with an increase in the austempering temperature, the thickness of the bainitic ferrite plates increased from 0.31 μm at 375 °C to 0.63 μm at 450 °C and a coarser microstructure was obtained. The results of this study showed that the austempering transformation in Al-alloyed ductile iron will result in the formation of an ausferritic structure.

description: We continue the exploration of the BaLROG (Bars in Low Redshift Optical Galaxies) sample: 16 large mosaics of barred galaxies observed with the integral field unit SAURON. We quantify the influence of bars on the composition of the stellar component. We derive linestrength indices of H$β$, Fe5015 and Mgb. Based on single stellar population (SSP) models, we calculate ages, metallicities and [Mg/Fe] abundances and their gradients along the bar major and minor axes. The high spatial resolution of our data allows us to identify breaks among index and SSP profiles, commonly at 0.13$\pm$0.06 bar length, consistent with kinematic features. Inner gradients are about ten times steeper than outer gradients and become larger when there is a central rotating component, implying that the gradients are not independent of dynamics and orbits. Central ages appear to be younger for stronger bars. Yet, the bar regions are usually old. We find a flattening of the iron (Fe5015) and magnesium (Mgb) outer gradients along the bar major axis, translating into a flattening of the metallicity gradient. This gradient is found to be 0.03$\pm$0.07 dex/kpc along the bar major axis while the mean value of the bar minor axis compares well with that of an unbarred control sample and is significantly steeper, namely -0.20$\pm$0.04 dex/kpc. These results confirm recent simulations and discern the important localized influence of bars. The elevated [Mg/Fe] abundances of bars and bulges compared to the lower values of discs suggest an early formation, in particular for early type galaxies.
