description: We combine the methods of Hamiltonian Truncation and the recently proposed generalisation of the S-matrix bootstrap that includes local operators to determine the two-particle scattering amplitude and the two-particle form factor of the stress tensor at $s>0$ in the 2d $ϕ^4$ theory. We use the form factor of the stress tensor at $s\le 0$ and its spectral density computed using Lightcone Conformal Truncation (LCT), and inject them into the generalized S-matrix bootstrap set-up. The obtained results for the scattering amplitude and the form factor are fully reliable only in the elastic regime. We independently construct the "pure" S-matrix bootstrap bounds (bootstrap without including matrix elements of local operators), and find that the sinh-Gordon model and its analytic continuation the "staircase model" saturate these bounds. Surprisingly, the $ϕ^4$ two-particle scattering amplitude also very nearly saturates these bounds, and moreover is extremely close to that of the sinh-Gordon/staircase model.

description: This paper deals with the quasilinear attraction-repulsion chemotaxis system \begin{align*} \begin{cases} u_t=\nabla\cdot \big((u+1)^{m-1}\nabla u -χu(u+1)^{p-2}\nabla v +ξu(u+1)^{q-2}\nabla w\big) +f(u), \\[1.05mm] 0=Δv+αu-βv, \\[1.05mm] 0=Δw+γu-δw \end{cases} \end{align*} in a bounded domain $Ω\subset \mathbb{R}^n$ ($n \in \mathbb{N}$) with smooth boundary $\partialΩ$, where $m, p, q \in \mathbb{R}$, $χ, ξ, α, β, γ, δ>0$ are constants. Moreover, it is supposed that the function $f$ satisfies $f(u)\equiv0$ in the study of boundedness, whereas, when considering blow-up, it is assumed that $m>0$ and $f$ is a function of logistic type such as $f(u)=λu-μu^κ$ with $λ\ge 0$, $μ>0$ and $κ>1$ sufficiently close to~$1$, in the radially symmetric setting. In the case that $ξ=0$ and $f(u) \equiv 0$, global existence and boundedness have been proved under the condition $p0$. This paper classifies boundedness and blow-up into the cases $pq$ without any condition for the sign of $χα-ξγ$ and the case $p=q$ with $χα-ξγ<0$ or $χα-ξγ>0$.

description: We study the structure and dynamics of entanglement in CFTs and black holes. We use a local entanglement measure, the entanglement contour, which is a spatial density function for von Neumann entropy with some additional properties. The entanglement contour can be calculated in many 1+1d condensed matter systems and simple models of black hole evaporation. We calculate the entanglement contour of a state excited by a splitting quench, and find universal results for the entanglement contours of low energy non-equilibrium states in 2d CFTs. We also calculate the contour of a non-gravitational bath coupled to an extremal AdS$_2$ black hole, and find that the contour only has finite support within the bath, due to an island phase transition. The particular entanglement contour proposal we use quantifies how well the bath's state can be reconstructed from its marginals, through its connection to conditional mutual information, and the vanishing contour is a reflection of the protection of bulk island regions against erasures of the boundary state.

description: We show that if the lepton flavor violating $μ\rightarrow e γ$ process is observed in the MEG II experiment, the initial density of primordial black holes (PBHs) can be constrained with the scotogenic dark matter. As a benchmark case, if the PBH evaporation occurs in the radiation dominated era, the initial density may be $2\times 10^{-17} \lesssim β\lesssim 3 \times 10^{-16}$ for $\mathcal{O}$ (TeV) scale dark sector in the scotogenic model where $β=ρ_{\rm PBH}/ρ_{\rm rad}$ is the ratio of the PBH density $ρ_{\rm PBH}$ to the radiation density $ρ_{\rm rad}$ at the time of PBH formation. As an other benchmark case, if PBHs evaporate in the PBH dominated era, the initial density may be $1 \times 10^{-8} \lesssim β\lesssim 3 \times 10^{-7}$ for $\mathcal{O}$ (GeV) scale dark matter with other $\mathcal{O}$ (TeV) scale particles in the scotogenic model.

The main diagnostic character of the Merodon melanocerus species group is the presence of a patch of dense and strong yellow pile on the metatrochanter (Fig. 3A: marked with arrow). The melanocerus species subgroup has the oral margin notched, produced forward, and bare (Fig. 3B: marked with arrow), while the planifacies species subgroup has the oral margin reduced and microtrichose.

description: Jet-medium interaction involves two important effects: jet energy loss and medium response. The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions. In this work, we perform a systematic study on how the lost energy from hard jets evolves with the bulk medium and redistributes in the final state of heavy-ion collisions via a multi-phase transport model. In particular, the ($Δη, Δϕ$) distribution of charged particles with respect to the jet axis and jet shape function are studied for various Pb+Pb collision centralities and for different transverse momentum intervals of charged particles. Our numerical result shows a strong enhancement of soft particles at large angles for Pb+Pb collisions relative to p+p collisions at the LHC, qualitatively consistent with recent CMS data. This indicates that a significant fraction of the lost energy from hard jets is carried by soft particles at large angles away from the jet axis.

description: Steering criteria are conditions whose violation excludes the possibility of describing the observed measurement statistics with local hidden state (LHS) models. When the available data do not allow to exclude arbitrary LHS models, it may still be possible to exclude LHS models with a specific separability structure. Here, we derive experimentally feasible criteria that put quantitative bounds on the multipartite entanglement of LHS. Our results reveal that separable states may contain hidden entanglement that can be unlocked by measurements on another system, even if no steering between the two systems is possible.

description: Der seit rund 130 Jahren in vielen Gewässern Europas ausgesetzte Sonnenbarsch Lepomis gibbosus konnte sich zwar etablieren, kam aber bisher in Mitteleuropa nur sehr lokal in relativ kleinen und unbeständigen Populationen vor. Erst in den letzten Jahren ist in Mitteldeutschland eine deutliche Tendenz zur Vermehrung und Ausbreitung zu beobachten. Das wird vermutlich durch die Klimaerwärmung begünstigt, da die klimatischen Verhältnisse für diese in Nordamerika etwa zwischen 32 und 51 Grad nördlicher Breite beheimatete Fischart nicht optimal sind. Auch der sogenannte time-lag, eine bei vielen Neobiota zu beobachtende mehrjährige Zeitdifferenz zwischen Einführung und eigenständiger Ausbreitung, kommt als Ursache der gegenwärtigen Expansion in Betracht. Es werden einige neue Vorkommen in Sachsen-Anhalt aufgeführt und mögliche Ursachen der aktuellen Ausbreitung diskutiert. Beschleunigt durch den sogenannten Gründereffekt könnte sich der Kürbiskern-Sonnenbarsch in Europa zu einer eigenständigen neuen Art („Lepomis europaeus“) entwickeln.
description: The Pumpkinseed sunfish Lepomis gibbosus, native ranging in North America nearly between 32 and 51 degree of latitude, is established as an alien species in Europe since nearly 130 years. Until now this species occurs in the Middle of Germany only in local and inconstant populations. In last years Pumpkinseed sunfish extended the frequency and density of his populations. Climate warming or time-lag may be the reasons for this accumulation, because climatic conditions in Germany are not optimal for this species occurring in more southern areas. Some new locations in Saxony-Anhalt were advised and possible reasons of the extending and increasing of the species are discussed.

description: We present the Regensburg Breast Shape Model (RBSM) -- a 3D statistical shape model of the female breast built from 110 breast scans acquired in a standing position, and the first publicly available. Together with the model, a fully automated, pairwise surface registration pipeline used to establish dense correspondence among 3D breast scans is introduced. Our method is computationally efficient and requires only four landmarks to guide the registration process. A major challenge when modeling female breasts from surface-only 3D breast scans is the non-separability of breast and thorax. In order to weaken the strong coupling between breast and surrounding areas, we propose to minimize the variance outside the breast region as much as possible. To achieve this goal, a novel concept called breast probability masks (BPMs) is introduced. A BPM assigns probabilities to each point of a 3D breast scan, telling how likely it is that a particular point belongs to the breast area. During registration, we use BPMs to align the template to the target as accurately as possible inside the breast region and only roughly outside. This simple yet effective strategy significantly reduces the unwanted variance outside the breast region, leading to better statistical shape models in which breast shapes are quite well decoupled from the thorax. The RBSM is thus able to produce a variety of different breast shapes as independently as possible from the shape of the thorax. Our systematic experimental evaluation reveals a generalization ability of 0.17 mm and a specificity of 2.8 mm. To underline the expressiveness of the proposed model, we finally demonstrate in two showcase applications how the RBSM can be used for surgical outcome simulation and the prediction of a missing breast from the remaining one. Our model is available at https://www.rbsm.re-mic.de/.

description: Radiation management in climate engineering - an overview: Climate engineering methods that intervene in the radiation budget and thus in the energy budget of the earth are subsumed under the term radiation management. The proposed methods almost all rely on redirecting incoming solar radiation in such a way that this reduces the warming at the earth's surface by a certain amount. One proposal also involves increasing outgoing thermal radiation. The potential effectiveness of the methods is highly variable. What they have in common is the possibility for undesirable meteorological or environmental side effects. This contribution provides a first overview of the variety of methods, more detailed information can be found in the following sub-chapters.

description: We provide evidence for conjectural dualities between nonrelativistic Chern-Simons-matter theories and theories of (fractional, nonAbelian) quantum Hall fluids in $2+1$ dimensions. At low temperatures, the dynamics of nonrelativistic Chern-Simons-matter theories can be described in terms of a nonrelativistic quantum mechanics of vortices. At critical coupling, this may be solved by geometric quantisation of the vortex moduli space. Using localisation techniques, we compute the Euler characteristic $χ(\mathcal{L}^λ)$ of an arbitrary power $λ$ of a quantum line bundle $\mathcal{L}$ on the moduli space of vortices in $U(N_c)$ gauge theory with $N_f$ fundamental scalar flavours on an arbitrary closed Riemann surface. We conjecture that this is equal to the dimension of the Hilbert space of vortex states when the area of the metric on the spatial surface is sufficiently large. We find that the vortices in theories with $N_c = N_f = λ$ behave as fermions in the lowest nonAbelian Landau level, with strikingly simple quantum degeneracy. More generally, we find evidence that the quantum vortices may be regarded as composite objects, made of dual anyons. We comment on potential links between the dualities and three-dimensional mirror symmetry. We also compute the expected degeneracy of local Abelian vortices on the $Ω$-deformed sphere, finding it to be a $q$-analog of the undeformed case.

description: Bei Nietleben hat der Bergbau auf Braunkohle schon im 19. Jh. die Landschaft und die Struktur der Wirtschaft verändert sowie durch Zunahme der Bevölkerung die Siedlung Nietleben vergrößert. Anliegen dieses Beitrags ist die Entwicklung des Braunkohlenbergbaus bei Nietleben. Die neuen Erkenntnisse gründen sich fast gänzlich auf das Studium von Akten des ehemaligen Oberbergamtes Halle im Landesarchiv Sachsen-Anhalt. Die Braunkohle tritt bei Nietleben mit einem Unterflöz aus dem Oberen Eozän und einem Oberflöz aus dem Unteren Oligozän auf. Die Gruben Neuglück, Wilhelm und Charlotte bebauten von 1826 bis 1855 nur das Oberflöz mit einem Tagebau sowie mehreren Schächten und Tagesstrecken. Die von der Gemeinde Nietleben 1826 aufgenommene Grube Neuglück kam 1837 durch Kauf in die Hand des Kaufmanns J.G.Boltze. Die Nähe zur Stadt Halle hat die Entwicklung des Braunkohlenbergbaus bei Nietleben begünstigt. Bis 1840 wurden 253750 t Braunkohle gefördert. Die 1834 installierte Dampfmaschine zur Hebung des Wassers war in der Umgebung von Halle die erste Dampfmaschine in einer Braunkohlengrube. Die Besitzer der drei Gruben begannen am Ende der 1830er Jahre eine Zusammenarbeit mit dem Ziel einer Konsolidierung.
description: At Nietleben, brown coal mining had already changed the landscape and the structure of the economy in the 19th century and, by increasing the population, enlarged the settlement of Nietleben. The purpose of this article is to discuss the development of brown coal mining at Nietleben. The new findings are based almost entirely on the study of files from the former Oberbergamt Halle in the Landesarchiv Sachsen-Anhalt. Brown coal occurs in Nietleben with a lower seam from the Upper Eocene and an upper seam from the Lower Oligocene. The mines Neuglück, Wilhelm and Charlotte built from 1826 to 1855 only the upper seam with an open cast as well as several shafts and galleries. The Neuglück mine, which was taken up by the municipality of Nietleben in 1826, was bought by the merchant J.G. Boltze in 1837. The proximity to the city of Halle has favoured the development of brown coal mining at Nietleben. Up to and including 1840 253750 tonnes of brown coal had been mined. The steam engine installed in 1834 to lift the water was the first steam engine in a brown coal mine in the vicinity of Halle. At the end of the 1830s, the owners of the three mines began working together with the aim of consolidation

description: Quantum scattering amplitudes for massive matter have received new attention in connection to classical calculations relevant to gravitational-wave physics. Amplitude methods and insights are now employed for precision computations of observables needed for describing the gravitational dynamics of bound massive objects such as black holes. An important direction is the inclusion of spin effects needed to accurately describe rotating (Kerr) black holes. Higher-spin amplitudes introduced by Arkani-Hamed, Huang and Huang at three points have by now a firm connection to the effective description of Kerr black-hole physics. The corresponding Compton higher-spin amplitudes remain however an elusive open problem. Here we draw from results of the higher-spin literature and show that physical insights can be used to uniquely fix the Compton amplitudes up to spin 5/2, by imposing a constraint on a three-point higher-spin current that is a necessary condition for the existence of an underlying unitary theory. We give the unique effective Lagrangians up to spin $5/2$, and show that they reproduce the previously-known amplitudes. For the multi-graviton amplitudes analogous to the Compton amplitude, no further corrections to our Lagrangians are expected, and hence such amplitudes are uniquely predicted. As an essential tool, we introduce a modified version of the massive spinor-helicity formalism which allows us to conveniently obtain higher-spin states, propagators and compact expressions for the amplitudes.

description: Um die meist nur hypothetischen Spekulationen über den Versauerungszustand des Teutoburger Waldes durch weitere empirische Daten zu prüfen, analysiert diese Arbeit die hydrochemischen Kennwerte einer Quelle aus einem Silikatbuchenwald im Waller Berg/nördlicher Teutoburger Wald. Die Quellwasserdaten werden nach anerkannt gültigen Indikatoren der Gewässerversauerung ausgewertet. Ein Versauerungsquotient < 1, eine Alkalinität im negativen Bereich von -0,62 mmolc L-1, ein Säuregrad von pH 4,0 und eine Aluminiumkonzentration von 4,8 mg L-1 weisen dem Quellwasser die Versauerungsstufe „stark versauert“ zu. Die Typisierung des Quellwassers bestätigt die Einstufung, dass auf der Kationenseite Aluminium, auf der Anionenseite Sulfat dominieren, wobei das Hydrogen-carbonat fehlt. Die im Vergleich zum Jahr 2003 zurückgehende Konzentration der Schlüsselsubstanz anthropogener Gewässerversauerung, des Aluminiums, deutet zwar eine Entsauerung an, ohne aber die Versauerung aufzuheben. Die Alkalinität der Waller Quelle liegt noch im derart tiefen, negativen Bereich, dass der Quellstandort von einer Erholung im biocönotischen Sinne weit entfernt ist.
description: To examine the mostly hypothetical speculations about the acidification state of the Teutoburg Forest by using further empirical data, this article analyses the hydro-chemical characteristics of a spring water in an acidophilic beech forest of the northern Teutoburg Forest, the Waller Mountain. The spring water data are evaluated on the basis of usual indicators of water acidification. An acidification quotient < 1, a negative alkalinity of ‒ 0,62 mmolc L-1, an acidification grade of pH 4.0 and a concentration of aluminium of 4.8 mg L-1 assign the acidification degree “strongly acidified” to the spring. The typification of the spring water confirms this classification: aluminum dominates the cation side, sulphate the anion side of the equivalent rank, hydrogen carbonate is missing. Indeed, the concentration of aluminium, the key substance of anthropogenic acidification, has declined between 2003 and 2018 and, thus, suggests a de-acidification, but without removing the acidification. The alkalinity of the spring water is still so deeply negative that the spring stand is far from recovering biocoenotically.

Modular symmetry is advantageous because it reduces the usage of extra scalar fields significantly. Moreover, the Yukawa couplings are expressed in terms of Dedekind eta functions, which also have a $q$ expansion form, utilized to achieve numerical simplicity. Our proposed model includes six heavy fermion superfields i.e., $\mathcal{N}_{Ri}$, $\mathcal{S}_{Li}$ and a weighton. The study of neutrino phenomenology becomes simplified and effective by the usage of $A^\prime_5$ modular symmetry, which provides us a well defined mass structure for the lepton sector. Here, we observe that all the neutrino oscillation parameters, as well as the effective electron neutrino mass in neutrinoless double beta decay can be accommodated in this model. We also briefly discuss the lepton flavor violating decays $\ell_i \to \ell_j γ$ and comment on non-unitarity of lepton mixing matrix.

description: Chaos in semiconductor lasers or other optical systems has been intensively studied in the past two decades. However, modulation around threshold has received much less attention, in particular in gain-modulated semiconductor lasers. In this article, we investigate the bifurcation sequence which appears with pump modulation in the threshold region with a large amplitude and different values of modulation frequency. Modulation around threshold necessarily includes ``below-threshold'' dynamics, which can be effectively displayed only through through a nonlinear visualization of the oscillations. The irregular temporal behaviour is examined at various modulation frequencies and amplitudes, highlighting a possible route to chaos for very large amplitude modulation in the near-threshold region. The addition of the (average) spontaneous emission to the lasing mode enables a coupled dynamics between photons and carriers even below threshold, thus extending the pump range in which the modulation actively modifies the laser behaviour. We also report on the existence of a transition between similar attractors characterized by a temporal transient which depends on the amplitude of the modulation driving the pump.

description: In this paper we propose a noncommutative generalization of the relationship between compact Kähler manifolds and complex projective algebraic varieties. Beginning with a prequantized Kähler structure, we use a holomorphic Poisson tensor to deform the underlying complex structure into a generalized complex structure, such that the prequantum line bundle and its tensor powers deform to a sequence of generalized complex branes. Taking homomorphisms between the resulting branes, we obtain a noncommutative deformation of the homogeneous coordinate ring. As a proof of concept, this is implemented for all compact toric Kähler manifolds equipped with an R-matrix holomorphic Poisson structure, resulting in what could be called noncommutative toric varieties. To define the homomorphisms between generalized complex branes, we propose a method which involves lifting each pair of generalized complex branes to a single coisotropic A-brane in the real symplectic groupoid of the underlying Poisson structure, and compute morphisms in the A-model between the Lagrangian identity bisection and the lifted coisotropic brane. This is done with the use of a multiplicative holomorphic Lagrangian polarization of the groupoid.

description: Many applications in quantum communication, sensing and computation need provably quantum non-Gaussian light. Recently such light, witnessed by a negative Wigner function, has been estimated using homodyne tomography from a single atom dispersively coupled to a high-finesse cavity. This opens an investigation of quantum non-Gaussian light for many experiments with atoms and solid-state emitters. However, at their early stage, an atom or emitter in a cavity system with different channels to the environment and additional noise are insufficient to produce negative Wigner functions. Moreover, homodyne detection is frequently challenging for such experiments. We analyse these issues and prove that such cavities can be used to emit quantum non-Gaussian light employing single-photon detection in the Hanbury Brown and Twiss configuration and quantum non-Gaussianity criteria suitable for this measurement. We investigate in detail cases of considerable cavity leakage when the negativity of the Wigner function disappears completely. Advantageously, quantum non-Gaussian light can be still conclusively proven for a large set of the cavity parameters at the cost of overall measurement time, even if noise is present.

description: Deep learning has an increasing impact to assist research, allowing, for example, the discovery of novel materials. Until now, however, these artificial intelligence techniques have fallen short of discovering the full differential equation of an experimental physical system. Here we show that a dynamical neural network, trained on a minimal amount of data, can predict the behavior of spintronic devices with high accuracy and an extremely efficient simulation time, compared to the micromagnetic simulations that are usually employed to model them. For this purpose, we re-frame the formalism of Neural Ordinary Differential Equations (ODEs) to the constraints of spintronics: few measured outputs, multiple inputs and internal parameters. We demonstrate with Spin-Neural ODEs an acceleration factor over 200 compared to micromagnetic simulations for a complex problem -- the simulation of a reservoir computer made of magnetic skyrmions (20 minutes compared to three days). In a second realization, we show that we can predict the noisy response of experimental spintronic nano-oscillators to varying inputs after training Spin-Neural ODEs on five milliseconds of their measured response to different excitations. Spin-Neural ODE is a disruptive tool for developing spintronic applications in complement to micromagnetic simulations, which are time-consuming and cannot fit experiments when noise or imperfections are present. Spin-Neural ODE can also be generalized to other electronic devices involving dynamics.

description: Artificially brightened surfaces to increase albedo: Climate-Engineering by altering surface albedo seems like an easy-to-understand solution to reduce global warming. However, the interventions are substantial, whether by altering ecosystems or covering surfaces with reflective materials, and their consequences are largely unstudied. Moreover, the costs are disproportionate to those of the much more effective reduction of greenhouse gases. Nevertheless, some measures appear to make sense, at least regionally in agriculture and in cities, in terms of changing the local climate.

description: We present spatially resolved measurements of cool gas flowing into and out of the Milky Way (MW), using archival ultraviolet spectra of background quasars from the Hubble Space Telescope/Cosmic Origins Spectrograph. We co-add spectra of different background sources at close projected angular separation on the sky. This novel stacking technique dramatically increases the signal-to-noise ratio of the spectra, allowing detection of low column density gas (down to $EW$ > 2 mA). We identify absorption as inflowing or outflowing, by using blue/redshifted high velocity cloud (HVC) absorption components in the Galactocentric rest frame, respectively. The mass surface densities of inflowing and outflowing gas both vary by more than an order of magnitude across the sky, with mean values of $\langle Σ_{in}\rangle \gtrsim 10^{4.6\pm0.1}$ $M_{\odot}\,\mathrm{kpc}^{-2}$ for inflowing gas and $\langle Σ_{out}\rangle \gtrsim 10^{3.5\pm 0.1}$ $M_{\odot}\,\mathrm{kpc}^{-2}$ for outflowing gas, respectively. The mass flow rate surface densities (mass flow rates per unit area) also show large variation across the sky with $\langle \dotΣ(d)_{in}\rangle \gtrsim (10^{-3.6\pm0.1})(d/12 \mathrm{kpc})^{-1} M_{\odot}\,\mathrm{kpc}^{-2} \mathrm{yr}^{-1}$ for inflowing and $\langle \dotΣ(d)_{out}\rangle \gtrsim (10^{-4.8\pm0.1})(d/12\,\mathrm{kpc})^{-1} M_{\odot}\,\mathrm{kpc}^{-2}\,\mathrm{yr}^{-1}$ for outflowing gas, respectively. The regions with highest surface mass density of inflowing gas are clustered at smaller angular scales ($θ< 40^\circ$). This indicates that most of the mass in inflowing gas is confined to small, well-defined structures, whereas the distribution of outflowing gas is spread more uniformly throughout the sky. Our study confirms that the MW is predominantly accreting gas, but is also losing a non-negligible mass of gas via outflow.

Linking Khotan and Dūnhuáng: Buddhist Narratives in Text and Image
Creators: name: Anderl, Christoph
Publisher: name: Entangled Religions
Year: 2018

description: In the propagation and spread of Buddhism throughout Asia, jātaka and avadāna narratives played a decisive role, both in the form of texts and iconographical representations. In this paper I will focus on another set of narratives which enjoyed great popularity in the Dūnhuáng area during the later Tang and Five Dynasties period, dealing with historical projections concerning the origin and transmission of Buddhism. In this stories, “Auspicious Statues” (ruìxiàng 瑞像) play a key role. These “living” statues were thought to have moved from Indian monasteries to Khotan and other regions, serving as agents of the transmission of the Dharma in these areas. Besides reflecting religious key concern during that period, the historical narratives on the spread of Buddhism also give witness to the close diplomatic and family relations between Dunhuang and the Kingdom of Khotan during that period.
