description: We show theoretically that photonic crystal membranes cause large variations in the spontaneous emission rate of dipole emitters, not only inside but also in the near-field above the membranes. Our three-dimensional finite difference time-domain calculations reveal an inhibition of more than five times and an enhancement of more than ten times for the spontaneous emission rate of emitters with select dipole orientations and frequencies. Furthermore we demonstrate theoretically, the potential of a nanoscopic emitter attached to the end of a glass fiber tip as a local probe for mapping the large spatial variations of the photonic crystal local radiative density of states. This arrangement is promising for on-command modification of the coupling between an emitter and the photonic crystal in quantum optical experiments.

description: We give the results for all the one-loop propagators, including finite parts, in the Coulomb gauge. In finite parts we find new non-rational functions in addition to the single logarithms of the Feynman gauge. Of course, the two gauges must agree for any gauge invariant function. We revise the manuscript hep-th/0311118v2 and Eur.Phys.J.C37, 307-313(2004) in accordance with the notation and correct Feynman rules for the Coulomb gauge in Minkowski space found in [16]. The high-energy behaviour of the proper two-point functions is added in Appendix C.

Circumstellar Light Echo as a Possible Origin of the Polarization of Type IIP Supernovae

description: Type IIP supernovae (SNe IIP) are the most common class of core-collapse SNe. They often show rapid increase of polarization degree in the late phase. This time evolution is generally believed to originate from the emergence of an inner aspherical core, while an effect of polarized-scattered echoes by circumstellar (CS) dust around the SN may also substantially contribute to this polarization feature. In this study, we examine the effects of the scatted echoes on the SN polarization through radiative transfer simulations for various geometry and amount of CS dust. It has been found that asymmetrically-distributed CS dust, which is generally inferred for red supergiants, could reproduce the observed polarization features. We have applied our results to SNe 2004dj and 2006ov, deriving the geometry and amount of CS dust to explain their observed polarization features in this scenario. For both SNe, the blob-like or bipolar distribution of CS dust rather than the disk-like distribution is favored. The derived dust mass $M_{\mathrm{dust}}$ in the blob model (the bipolar CS dust model) for SNe 2004dj and 2006ov are $\sim 7.5 \times 10^{-4}$ M$_{\odot}$ ($\sim 8.5 \times10^{-4}$ M$_{\odot}$) and $\sim 5.2 \times 10^{-4}$ M$_{\odot}$ ($\sim 1.3 \times10^{-3}$ M$_{\odot}$), respectively. Even in the case where this process would not play a dominant role in the observed polarization signals, this effect should in principle contribute to it, the strength of which depends on the nature of CS dust. Therefore, this effect must be taken into account in discussing multi-dimensional structure of an SN explosion through polarimetric observations.

description: Shell effects in nuclei close to the neutron-drip lines have been investigated. It has been demonstrated in the relativistic mean-field theory that nuclei very far from stability manifest the shell effects strongly. This behaviour is in accord with the predictions of nuclear masses in the finite-range droplet model including shell corrections. As a consequence we find a large neutron halo in nuclei near the neutron-drip line. The shell effects predicted in the existing Skyrme mean-field theory in comparison are significantly weaker than those of the other approaches.

description: Precision orbit determination methods, along with a new technique to compute relative data weights, have been applied to the determination of the Earth’s gravity field and other geophysical parameters from the combination of satellite ground-based tracking data, satellite altimetry data, and the surface gravimetry data. The University of Texas Earth's gravity field model, TEG-2, was determined from data sets collected from fifteen satellites, spanning the inclination ranges from 15° to 115°, and surface gravity data. The satellite measurements include laser ranging data, doppler range-rate data, and satellite-toocean radar altimeter data, which include the direct height measurement and the differenced measurements at ground track crossings (crossover measurements). The terrestrial gravimetry data used in the TEG-2 solution were provided from the Ohio State University 1°×1° area-mean free-air gravity anomaly data and elevation data. The estimated parameters in the TEG-2 solution include GM - gravitational constant of the Earth, geopotential coefficients complete to degree and order 50, selected dynamical tide coefficients, coordinates of the doppler tracking stations, two separate sets of surface spherical harmonics coefficients complete to degree and order 10 for Seasat and Geosat altimeter-derived quasi-stationary sea surface topography. Error assessment and calibration of the TEG-2 solution and formal error covariance have been performed. Observation residual combined with covariance prediction analysis indicate that a level of internal consistency has been achieved in the TEG-2 solution, and a calibration factor has been determined for the TEG-2 formal error covariance matrix so that the resulting covariance presents a realistic accuracy of TEG-2 solution. The improvement of the TEG-2 geopotential solution presented in this investigation is due in large part to the optimal weighting technique applied to the simultaneous solution for the topography, the gravity field, and the satellite orbit. The accuracy of geographically correlated mean for Topex radial orbit predicted from the 36×36 part of the TEG-2 geopotential error covariance is about 11 cm, and the global accuracy of geoid undulation predicted from the 50×50 part of the TEG-2 geopotential error covariance is about 1.6 m.

Satellite Orbit Perturbations Due to the Geopotential

geopotential

description: Satellite-borne radar altimeters have the capability of measuring the distance from the satellite platform to the ocean surface with an accuracy of five centimeters or less. To fully exploit the geophysical information contained in this data, it is necessary to have independent knowledge of the geocentric satellite distance to a comparable level of accuracy. Current altimeter satellite ephemerides fail this requirement by at least an order of magnitude. The radial errors contained in the estimated orbits are primarily a result of inadequacies in the modeling of the Earth's gravity field. To better understand the limitations this orbit error imposes on the analysis of the altimeter data, this study details the temporal and spatial characteristics of the radial orbit perturbations produced by the geopotential. The temporal description fully describes the frequency spectrum of the perturbations, and the spatial description provides a direct method for quantifying the perturbations on a geographical basis. These results are used to analyze the expected radial orbit perturbations of the altimeter satellite to be flown by the proposed TOPEX Mission. To facilitate other possible applications, the geopotential perturbations in the along-track and cross-track directions are presented also.

description: Reducing noise in quantum systems is a major challenge towards the application of quantum technologies. Here, we propose and demonstrate a scheme to reduce noise using a quantum autoencoder with rigorous performance guarantees. The quantum autoencoder learns to compresses noisy quantum states into a latent subspace and removes noise via projective measurements. We find various noise models where we can perfectly reconstruct the original state even for high noise levels. We apply the autoencoder to cool thermal states to the ground state and reduce the cost of magic state distillation by several orders of magnitude. Our autoencoder can be implemented using only unitary transformations without ancillas, making it immediately compatible with the state of the art. We experimentally demonstrate our methods to reduce noise in a photonic integrated circuit. Our results can be directly applied to make quantum technologies more robust to noise.

The theory is based on the notion of configurational forces in conjunction with a mechanical version of the second law. Kinking and curving of the crack are allowed under the assumption that the crack will propagate in a direction that maximizes the rate at which it dissipates energy."

description: We study 1 or 2 neighboring Mn impurities, as well as complexes of 1 Mn and 1 or 2 Mg ions in a 64 atoms supercell of GaN by means of density functional calculations. Taking into account the electron correlation in the local spin density approximation with explicit correction of the Hubbard term (the LSDA+U method) and full lattice relaxation we determine the nearest neighbor exchange J for a pair of Mn impurities. We find J to be ferromagnetic and of the order of about 18 meV in the Hamiltonian H=-2*J1*J2. That J is only weakly influenced by the U parameter (varying between 2 and 8 eV) and by the lattice relaxation. From a detailed analysis of the magnetization density distribution we get hints for a ferromagnetic super-exchange mechanism. Also the Mn valence was found to be 3+ without any doubt in the absence of co-doping with Mg. Co-doping with Mg leads to a valence change to 4+ for 1 Mg and to 5+ for 2 Mg. We show that the valence change can already be concluded from a careful analysis of the density of states of GaN doped with Mn without any Mg.

description: We design a control law for two agents to successfully track a level curve in the plane without explicitly estimating the field gradient. The velocity of each agent is decomposed along two mutually perpendicular directions, and separate control laws are designed along each direction. We prove that the formation center will converge to the neighborhood of the level curve with the desired level value. The algorithm is tested on some test functions used in optimization problems in the presence of noise. Our results indicate that in spite of the control law being simple and gradient-free, we are able to successfully track noisy planar level curves fast and with a high degree of accuracy.

description: The advent of ChatGPT has created a disparity between the original circumstances for which our educational systems were designed and the current reality of education.This thesis aims to set a perimeter for both what we should teach now and how.This is achieved through a mixed-methods approach, involving interviews with several educators at TU Wien, a survey conducted among both students and educators there, and a critical analysis of how systems like ChatGPT function aswell as their potential use in education.The findings indicate that while ChatGPT and systems like it are highly effective in certain aspects – such as summarising and personalising – and show promise in making education more accessible and efficient, they also pose a range of potential risks, including emotional manipulation, propagated biases, and misplaced trust.These risks, however, are often not adequately addressed in discussions about them.The conclusion drawn is that now is a time to educate not with but about ChatGPT, its potentials and risks. Emphasising the human elements in education,such as personal connections and interactions, is paramount for addressing the challenges that arise. ChatGPT can certainly serve as a tool; however, it should not be seen as a replacement for educators. As one interviewee in the study expressed,"Without a doubt, it simply needs people [...]."This, however, presents significant challenges for educational institutions, with resources being the most critical. The necessary changes are far from inexpensive.

range-based solutions

description: In the generation of the standard GRACE gravity fields, the K-Band Ranging (KBR) system data is used in its range-rate mode. Because time derivatives attenuate the gravity signal relative to the data noise at the lower frequencies, it is thought that solutions using range data might have better low-degree (low-frequency) characteristics. The purpose of this work is to detail the methods required to generate range-based solutions, to determine some of the properties of these solutions, and then to compare them to range-rate-based solutions. It is demonstrated that range-based solutions are feasible, and that the most effective KBR parameterization in this analysis is to estimate the bias parameter four times per orbital revolution, the bias-rate parameter twice per revolution, and the bias-acceleration and periodic parameters once per revolution. This parameterization yields an improvement in the accuracy of the earth oblateness term, C20, of almost a factor of three, compared to an independent measurement. However, this improvement comes at the expense of the accuracy of the higher-degree gravity coefficients.

description: Abstract—Background: Early-stage accelerator programs teach new entrepreneurs how to identify and exploit venture opportunities. In doing so, they implicitly teach these new entrepreneurs how to develop and iterate claims. But since this function of teaching persuasion has been implicit and generally unsystematic, it is unclear how well it works. Literature review: We review related literature on the venture development process, value propositions, and logic orientation (Goods-Dominant vs. Service-Dominant Logic). Research questions: 1. Does an entrepreneurship training program implicitly teach new entrepreneurs to make and iterate persuasive claims? 2. How effectively does it do so, and how can it improve? Research methodology: We examine one such accelerator program via a qualitative case study. In this case study, we collected interviews, observations, and artifacts, then analyzed them with thematic coding. Results/discussion: All teams had received previous entrepreneurship training and mentoring. However, they differed in their problem and logic orientations as well as their stage in the venture development process. These differences related to the extent to which they iterated value propositions in the program. Conclusions: We conclude with recommendations for improving how accelerator programs can better train new entrepreneurs to communicate and persuade.

We endow $\mathcal{C}_ω(X)$ with the topology of uniform convergence on bounded sets and prove that the modulus of continuity of the generic mapping in $\mathcal{C}_ω(X)$, in the sense of Baire categories, is precisely $ω$. Some related results in spaces of bounded mappings and in the topology of pointwise convergence are also discussed. This note can be seen as a completion of various results due to F. Strobin, S.

Zur Erreichung eines guten Zustands in unseren Binnen- und Küstengewässern und der Ostsee sind weiterhin Maßnahmen zur Reduzierung punktueller stofflicher Belastungen erforderlich. Neben Emissionen aus kommunalen Kläranlagen sind dabei auch andere Eintragspfade stärker in den Blick zu nehmen. Dies betrifft insbesondere Niederschlagswasser aus Siedlungsgebieten, von Verkehrsflächen, aber auch landwirtschaftlichen Betriebsflächen. Gleichzeitig rücken neue Verschmutzungsparameter und bisher nur unzureichend bewertbare Risikostoffe in den Fokus. Spätestens mit Veröffentlichung der Ergebnisse aus dem Stakeholder Dialog "Spurenstoffstrategie des Bundes" nimmt auch die Diskussion zur "4. Reinigungsstufe" Fahrt auf. Schon aus Gründen der Kosteneffizienz sind neben wasserwirtschaftlichen Maßnahmen zunehmend quellenorientierte Reduktionsansätze erforderlich. Dies gilt insbesondere für den ländlichen Raum und das Trennsystem mit zahlreichen diffus verteilten Einleitpunkten aus unterschiedlichen Quellen. Die Entwicklung und Umsetzung effektiver Maßnahmen erfordert deshalb ein gutes Systemverständnis, schlaues Engineering, effektive Verwaltung sowie eine ehrliche Erfolgskontrolle.

Furthermore, for each size at least three, we prove that, modulo term equivalence, there is a continuum of equational domains of that size.

description: Structural Mapping at 1:1000 scale of the Cambrian rocks within Beavertail State Park, Narragansett Basin, Rhode Island has revealed an early open to isoclinal fold generation (F₁) and axial planar foliation (S₁) followed by a later, more prominent, Evergent, N-trending non-coaxial fold generation (F₂) and associated foliation (S₂). A third map-scale folding phase is inferred from the NNE-trending, broad warping of S₂. Quartz veins are folded by and cross cut F₂ folds. N-S to NE-SW extension resulted in 1-10 m scale boudins that deform S₂. All of these structures are cross cut by NNE to ENEstriking faults and joints. Kinematic indicators show that the dominant motion on these faults was normal with minor sinistral and/or dextral motions. The Beaverhead Shear Zone that juxtaposes the Cambrian rocks with Pennsylvanian rocks of the Narragansett Basin deflects S₂ in a dextral sense, consistent with recorded motion elsewhere. Kink bands associated with faulting trend NNE to ENE and display WNW to NNW side up. Petrographic work reveals S₁ is a penetrative foliation defined by alignment of white micas. S₂ is a crenulation cleavage of S₁ that is enhanced by pressure solution. S₂ is the dominant foliation expressed in the field; however there are areas where S₁ is locally better developed. Siderite and quartz nodules overgrow S₁ and are wrapped by S₂. Mica, quartz and iron carbonate pressure shadows on these nodules are parallel to S₂. Fabric development and orientation, style, and sequence of structures found in the lower greenschist Cambrian rocks within and up to 4 km north of Beavertail State Park, RI are dissimilar to those associated with the Taconic and Acadian events, but identical to Alleghanian structures in Pennsylvanian aged rocks of the Narragansett Basin. These similarities indicate that the Cambrian rocks have exclusively recorded the Pennsylvanian-Permian Alleghanian orogeny, and could not have been in place in North America during the Ordovician Taconic and Devonian Acadian orogenies. Timing constraints indicate the collision of the Avalon microcontinent occurred during the late Pennsylvanian, whereas progressive deformation of the Pennsylvanian rocks of the Narragansett Basin and the Cambrian rocks took place during the Permian

description: The classical paradox of social choice theory asserts that there is no fair way to deterministically select a winner in an election among more than two candidates; the only definite collective preferences are between individual pairs of candidates. Combinatorially, one may summarize this information with a graph-theoretic tournament on n vertices (one per candidate), placing an edge from u to v if u would beat v in an election between only those two candidates (no ties are permitted). One well-studied procedure for selecting a winner is to specify a complete binary tree whose leaves are labeled by the candidates, and evaluate it by running pairwise elections between the pairs of leaves, sending the winners to successive rounds of pairwise elections which ultimately terminate with a single winner. This structure is called a voting tree. Much research has investigated which functions on tournaments are computable in this way. Fischer, Procaccia, and Samorodnitsky quantitatively studied the computability of the Copeland rule, which returns a vertex of maximum out-degree in the given tournament. Perhaps surprisingly, the best previously known voting tree could only guarantee a returned out-degree of at least log2 n, despite the fact that every tournament has a vertex of degree at least n−1 2 . In this paper, we present three constructions, the first of which substantially improves this guarantee to Θ(√ n). The other two demonstrate the richness of the voting tree universe, with a tree that resists manipulation, and a tree which implements arithmetic modulo three.

description: We compute an upper bound for the dimension of the tangent spaces at classical points of certain eigenvarieties associated with definite unitary groups, especially including the so-called critically refined cases. Our bound is given in terms of "critical types" and when our bound is minimized it matches the dimension of the eigenvariety. In those cases, which we explicitly determine, the eigenvariety is necessarily smooth and our proof also shows that the completed local ring on the eigenvariety is naturally a certain universal Galois deformation ring.

description: Quaternary tectonic and climate interactions have and continue to contribute to a substantial stratigraphic record that preserves the key regional events that result from the interplay of these dynamic processes. Near Yakutat Bay, Alaska, temperate glacial cover continuously manipulates and shapes the southern Alaskan margin and delivers substantial amounts of sediment annually. During cooler climatic periods, these glaciers, like most glaciers in Alaska, experience increases in volume and advance across the shelf. Using an integrated seismic data set, we investigate stratigraphic signatures buried along the shelf, between the present Yakutat and Alsek Sea Valleys, in order to understand the mechanics governing the regional glacial system during advance phases. Our investigations reveal four glacial unconformities, of which, two show preserved retreat sediment packages. The events are indicative of ice advance phases during the Little Ice Age (LIA), the Last Glacial Maxima (LGM), and two pre-LGM events. The events show dominance by ice expanse from the Malaspina and Alsek River districts. The LGM event transgresses the shelf and concentrates erosion in highly overdeepened troughs, somewhat analogous to ice stream behavior. In addition, associated with these regional events, we find a suite of large-scale channel forms, exhibiting widths between 0.6-4.2 km and depths between 49-353 m. The channels are highly eroded vertically relative to lateral extent; widths to thickness ratios of the buried channel deposits are 15.7 on average. The channels show good correlation with the interpreted erosional events and other stratigraphic signatures indicative of ice occupation, i.e. moraines, grounding lines, etc. The channels exhibit distinct facies and facies assemblages of variable thicknesses and occurrence and show common morphologic characteristics with one another, i.e. cross-cuts. The facies and assemblages appear dominated by glacio-proximal, glacio-fluvial and glacio-lacustrine/marine physical processes. The characteristic morphology of the channels implies they are subglacially derived, and facies suggest subsequent fill by subaerial/submarine processes after ice retreat. Based on morphologic interpretations of the channels and their associations with glacial stratigraphy and erosional events, we interpret them as tunnel valleys. Expanding on their predictable relationship with specific glacial stratigraphy, we conclude that the tunnel valleys are indicators of retreat following glacial advance periods, when significant amounts of ice and melt are available to initiate and generate large tunnel valley deposits. As such, we conclude that the tunnel valleys are useful paleoclimate indicators

description: The lightest $Z_2$ odd particle in the scotogenic model, referred to as scotogenic dark matter (DM), is a widely studied candidate for DM. This scotogenic DM is generated through well-known thermal processes as well as via the evaporation of primordial black holes (PBHs). Recent reports suggested that the curvature fluctuations of PBHs during an epoch dominated by these entities in the early universe can serve as the source of so-called induced gravitational waves (GWs). In this study, we demonstrate that stringent constraints on the mass of scotogenic DM and PBHs can be obtained through the detection of induced GWs using future detectors.

Analysis of the $B^+\to J/ψϕK^+$ data at low $J/ψϕ$ invariant masses and the $X(4140)$ and $X(4160)$ resonances

description: We have studied the $J/ψϕ$ mass distribution of the $B^+\to J/ψϕK^+$ reaction from threshold to about 4250 MeV, and find that one needs the contribution of the $X(4140)$ with a narrow width, together with the $X(4160)$ which accounts for most of the strength of the distribution in that region. The existence of a clear cusp at the $D_s^* \bar{D}_s^*$ threshold indicates that the $X(4160)$ resonance is strongly tied to the $D_s^* \bar{D}_s^*$ channel, which finds a natural interpretation in the molecular picture of this resonance.

Computational spectroscopy of helium-solvated molecules: effective inertia, from small He clusters toward the nano-droplet regime

description: Accurate computer simulations of the rotational dynamics of linear molecules solvated in He clusters indicate that the large-size (nano-droplet) regime is attained quickly for light rotors (HCN, CO) and slowly for heavy ones (OCS, N$_2$O, CO$_2$), thus challenging previously reported results. Those results spurred the view that the different behavior of light rotors with respect to heavy ones - including a smaller reduction of inertia upon solvation of the former - would result from the lack of adiabatic following of the He density upon molecular rotation. We have performed computer experiments in which the rotational dynamics of OCS and HCN molecules was simulated using a fictitious inertia appropriate to the other molecule. These experiments indicate that the approach to the nano-droplet regime, as well as the reduction of the molecular inertia upon solvation, is determined by the anistropy of the potential, more than by the molecular weight. Our findings are in agreement with recent infrared and/or microwave experimental data which, however, are not yet totally conclusive by themselves.

Convergence of stochastic particle systems undergoing advection and coagulation

description: The convergence of stochastic particle systems representing physical advection, inflow, outflow and coagulation is considered. The problem is studied on a bounded spatial domain such that there is a general upper bound on the residence time of a particle. The laws on the appropriate Skorohod path space of the empirical measures of the particle systems are shown to be relatively compact. The paths charged by the limits are characterised as solutions of a weak equation restricted to functions taking the value zero on the outflow boundary. The limit points of the empirical measures are shown to have densities with respect to Lebesgue measure when projected on to physical position space. In the case of a discrete particle type space a strong form of the Smoluchowski coagulation equation with a delocalised coagulation interaction and an inflow boundary condition is derived. As the spatial discretisation is refined in the limit equations, the delocalised coagulation term reduces to the standard local Smoluchowski interaction.

description: We model a radiating star undergoing dissipative gravitational collapse in the form of radial heat flux. The exterior of the collapsing star is described by the generalised Vaidya solution representing a mixture of null radiation and strings. Our model generalises previously known results of constant string density atmosphere to include inhomogeneities in the exterior spacetime. By utilising a causal heat transport equation of the Maxwell-Cattaneo form we show that relaxational effects are enhanced in the presence of inhomogeneities due to the string density.

description: Perturbative spectra and related factorization properties of one-loop open string amplitudes in the presence of a constant external background B are analysed in detail. While the pattern of the closed string spectrum, obtained after a careful study of the properly symmetrized amplitudes, turns out to be unaffected by the presence of B, a series of double open-string poles, which would be absent when B is turned off, can couple owing to a partial symmetry loss. These features are studied first in a bosonic setting and then generalized in the more satisfactory superstring context. When the background is of an ``electric'' type, a classical perturbative instability is produced beyond a critical value of the electric field. In the Seiberg-Witten limit this instability is the origin of the unphysical tachyonic cut occurring in the non-planar amplitudes of the corresponding noncommutative field theories.

description: We explore the class of trilevel equilibrium problems with a focus on energy-environmental applications and present a novel single-level reformulation for such problems, based on strong duality. To the best of our knowledge, only one alternative single-level reformulation for trilevel problems exists. This reformulation uses a representation of the bottom-level solution set, whereas we propose a reformulation based on strong duality. Our novel reformulation is compared to this existing formulation, discussing both model sizes and computational performance. In particular, we apply this trilevel framework to a power market model, exploring the possibilities of an international policymaker in reducing emissions of the system. Using the proposed methods, we are able to obtain globally optimal solutions for a five-node case study representing the Nordic countries and assess the impact of a carbon tax on the electricity production portfolio.

description: In this paper we propose a time discretization of a system of two parabolic equations describing diffusion-driven atom rearrangement in crystalline matter. The equations express the balances of microforces and microenergy; the two phase fields are the order parameter and the chemical potential. The initial and boundary-value problem for the evolutionary system is known to be well posed. Convergence of the discrete scheme to the solution of the continuous problem is proved by a careful development of uniform estimates, by weak compactness and a suitable treatment of nonlinearities. Moreover, for the difference of discrete and continuous solutions we prove an error estimate of order one with respect to the time step.

description: Abstract: "We discuss the problem of computing the volume of a convex body K in R[superscript n]. We review worst-case results which show that it is hard to deterministically approximate vol[subscript n]K and randomised approximation algorithms which show that with randomisation one can approximate very nicely. We then provide some applications of this latter result."
