description: Generative text-to-image models have gained great popularity among the public for their powerful capability to generate high-quality images based on natural language prompts. However, developing effective prompts for desired images can be challenging due to the complexity and ambiguity of natural language. This research proposes PromptMagician, a visual analysis system that helps users explore the image results and refine the input prompts. The backbone of our system is a prompt recommendation model that takes user prompts as input, retrieves similar prompt-image pairs from DiffusionDB, and identifies special (important and relevant) prompt keywords. To facilitate interactive prompt refinement, PromptMagician introduces a multi-level visualization for the cross-modal embedding of the retrieved images and recommended keywords, and supports users in specifying multiple criteria for personalized exploration. Two usage scenarios, a user study, and expert interviews demonstrate the effectiveness and usability of our system, suggesting it facilitates prompt engineering and improves the creativity support of the generative text-to-image model.

description: We examine the behavior of non-Gaussian states of light under the action of probabilistic noiseless amplification and attenuation. Surprisingly, we find that the mean field amplitude may decrease in the process of noiseless amplification -- or increase in the process of noiseless attenuation, a counterintuitive effect that Gaussian states cannot exhibit. This striking phenomenon could be tested with experimentally accessible non-Gaussian states, such as single-photon added coherent states. We propose an experimental scheme, which is robust with respect to the major experimental imperfections such as inefficient single-photon detection and imperfect photon addition. In particular, we argue that the observation of mean field amplification by noiseless attenuation should be feasible with current technology.

description: New reverberation mapping measurements of the size of the optical iron emission-line region in quasars are provided, and a tentative size-luminosity relation for this component is reported. Combined with lag measurements in low-luminosity sources, the results imply an emission-region size that is comparable to and at most twice that of the H$β$ line, and is characterized by a similar luminosity dependence. This suggests that the physics underlying the formation of the optical iron blends in quasars may be similar to that of other broad emission lines.

description: We report the discovery of Mothra, an extremely magnified monster star, likely a binary system of two supergiant stars, in one of the strongly lensed galaxies behind the galaxy cluster MACS0416. The star is in a galaxy with spectroscopic redshift $z=2.091$ in a portion of the galaxy that is parsecs away from the cluster caustic. The binary star is observed only on the side of the critical curve with negative parity but has been detectable for at least eight years, implying the presence of a small lensing perturber. Microlenses alone cannot explain the earlier observations of this object made with the Hubble Space Telescope. A larger perturber with a mass of at least $10^4$\,\Msun\ offers a more satisfactory explanation. Based on the lack of perturbation on other nearby sources in the same arc, the maximum mass of the perturber is $M< 2.5\times10^6$\,\Msun, making it the smallest substructure constrained by lensing above redshift 0.3. The existence of this millilens is fully consistent with the expectations from the standard cold dark matter model. On the other hand, the existence of such small substructure in a cluster environment has implications for other dark matter models. In particular, warm dark matter models with particle masses below 8.7\,keV are excluded by our observations. Similarly, axion dark matter models are consistent with the observations only if the axion mass is in the range $0.5\times10^{-22}\, {\rm eV} < m_a < 5\times10^{-22}\, {\rm eV}$.

description: SAO244567, the exciting star of the Stingray nebula, is rapidly evolving. Previous analyses suggested that it has heated up from an effective temperature of about 21kK in 1971 to over 50kK in the 1990s. Canonical post-asymptotic giant branch evolution suggests a relatively high mass while previous analyses indicate a low-mass star. Fitting line profiles from static and expanding non-LTE model atmospheres to the observed UV and optical spectra, taken during 1988-2013, allowed us to study the temporal change of effective temperature, surface gravity, mass-loss rate, and terminal wind velocity. In addition, we determined the chemical composition of the atmosphere. We find that the central star has steadily increased its effective temperature from 38kK in 1988 to a peak value of 60kK in 2002. During the same time, the star was contracting, as concluded from an increase in surface gravity from log g = 4.8 to 6.0 and a drop in luminosity. Simultaneously, the mass-loss rate declined from log (dM/dt/Msun/yr)=-9.0 to -11.6 and the terminal wind velocity increased from 1800km/s to 2800km/s. Since around 2002, the star stopped heating and has cooled down again to 55kK by 2006. It has a largely solar surface composition with the exception of slightly subsolar carbon, phosphorus, and sulfur. By comparison with stellar-evolution calculations, we confirm that SAO244567 must be a low-mass star (M < 0.55 Msun). However, the slow evolution of the respective stellar evolutionary models is in strong contrast to the observed fast evolution and the young planetary nebula with a kinematical age of only about 1000 years. We speculate that the star could be a late He-shell flash object. Alternatively, it could be the outcome of close-binary evolution. Then SAO244567 would be a low-mass (0.354 Msun) helium prewhite dwarf after the common-envelope phase, during which the planetary nebula was ejected.

description: In the human lower than normal concentrations of IgA in saliva have been found to be associated with stress. In studies of animal welfare and prolonged stress there is a need for nominvasive methods and assays of secretory IgA would be simple to develop for many species. In the present study we studied IgA in the chicken and compared levels of IgA in tears. serum and bile. Two strains of chickens were compared. The concentration of IgA in the lacrimal fluid of line C chickens was two-fold higher than that of line 151 chickens. Levels of IgA in their serum and bile where the same. Following on from the replication of avirulent Newcastle disease virus (NDV)1n the Harderian gland of thc nietitating membiane line C chickens contained NDV — specific lacrimal IgA to a titre of 102 whereas line 151 chickens contained none at 10-1-5. Both lines conmined NDV ~specific IgA in their bile to a titre of 103. Line 151 chickens therefore have a selective deficiency in lacrimal IgA compared to biliary IgA.

Computer Simulation of Quantum Dynamics in a Classical Spin Environment
Creators: name: Sergi, Alessandro
Publisher: name: arXiv
Year: 2014
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: In this paper a formalism for studying the dynamics of quantum systems coupled to classical spin environments is reviewed. The theory is based on generalized antisymmetric brackets and naturally predicts open-path off-diagonal geometric phases in the evolution of the density matrix. It is shown that such geometric phases must also be considered in the quantum-classical Liouville equation for a classical bath with canonical phase space coordinates; this occurs whenever the adiabatics basis is complex (as in the case of a magnetic field coupled to the quantum subsystem). When the quantum subsystem is weakly coupled to the spin environment, non-adiabatic transitions can be neglected and one can construct an effective non-Markovian computer simulation scheme for open quantum system dynamics in classical spin environments. In order to tackle this case, integration algorithms based on the symmetric Trotter factorization of the classical-like spin propagator are derived. Such algorithms are applied to a model comprising a quantum two-level system coupled to a single classical spin in an external magnetic field. Starting from an excited state, the population difference and the coherences of this two-state model are simulated in time while the dynamics of the classical spin is monitored in detail. It is the author's opinion that the numerical evidence provided in this paper is a first step toward developing the simulation of quantum dynamics in classical spin environments into an effective tool. In turn, the ability to simulate such a dynamics can have a positive impact on various fields, among which, for example, nano-science.

description: Visual-Semantic Embedding (VSE) networks can help search engines better understand the meaning behind visual content and associate it with relevant textual information, leading to more accurate search results. VSE networks can be used in cross-modal search engines to embed image and textual descriptions in a shared space, enabling image-to-text and text-to-image retrieval tasks. However, the full potential of VSE networks for search engines has yet to be fully explored. This paper presents Boon, a novel cross-modal search engine that combines two state-of-the-art networks: the GPT-3.5-turbo large language model, and the VSE network VITR (VIsion Transformers with Relation-focused learning) to enhance the engine's capabilities in extracting and reasoning with regional relationships in images. VITR employs encoders from CLIP that were trained with 400 million image-description pairs and it was fine-turned on the RefCOCOg dataset. Boon's neural-based components serve as its main functionalities: 1) a 'cross-modal search engine' that enables end-users to perform image-to-text and text-to-image retrieval. 2) a 'multi-lingual conversational AI' component that enables the end-user to converse about one or more images selected by the end-user. Such a feature makes the search engine accessible to a wide audience, including those with visual impairments. 3) Boon is multi-lingual and can take queries and handle conversations about images in multiple languages. Boon was implemented using the Django and PyTorch frameworks. The interface and capabilities of the Boon search engine are demonstrated using the RefCOCOg dataset, and the engine's ability to search for multimedia through the web is facilitated by Google's API.

description: Constructing supervised machine learning models for real-world video analysis require substantial labeled data, which is costly to acquire due to scarce domain expertise and laborious manual inspection. While data programming shows promise in generating labeled data at scale with user-defined labeling functions, the high dimensional and complex temporal information in videos poses additional challenges for effectively composing and evaluating labeling functions. In this paper, we propose VideoPro, a visual analytics approach to support flexible and scalable video data programming for model steering with reduced human effort. We first extract human-understandable events from videos using computer vision techniques and treat them as atomic components of labeling functions. We further propose a two-stage template mining algorithm that characterizes the sequential patterns of these events to serve as labeling function templates for efficient data labeling. The visual interface of VideoPro facilitates multifaceted exploration, examination, and application of the labeling templates, allowing for effective programming of video data at scale. Moreover, users can monitor the impact of programming on model performance and make informed adjustments during the iterative programming process. We demonstrate the efficiency and effectiveness of our approach with two case studies and expert interviews.

description: We define a new geometric flow, which we shall call the $K$-flow, on 3-dimensional Riemannian manifolds; and study the behavior of Thurston's model geometries under this flow both analytically and numerically. As an example, we show that an initially arbitrarily deformed homogeneous 3-sphere flows into a round 3-sphere and shrinks to a point in the unnormalized flow; or stays as a round 3-sphere in the volume normalized flow. The $K$-flow equation arises as the gradient flow of a specific purely quadratic action functional that has appeared as the quadratic part of New Massive Gravity in physics; and a decade earlier in the mathematics literature, as a new variational characterization of three-dimensional space forms. We show the short-time existence of the $K$-flow using a DeTurck-type argument.

description: Understanding the modification of jets and high-$p_T$ probes in small systems requires the integration of soft and hard physics. We present recent developments in extending the JETSCAPE framework to build an event generator, which includes correlations between soft and hard partons, to study jet observables in small systems. The multi-scale physics of the collision is separated into different stages. Hard scatterings are first sampled at binary collision positions provided by the Glauber geometry. They are then propagated backward in space-time following an initial-state shower to obtain the initiating partons' energies and momenta before the collision. These energies and momenta are then subtracted from the incoming colliding nucleons for soft-particle production, modeled by the 3D-Glauber + hydrodynamics + hadronic transport framework. This new hybrid approach (X-SCAPE) includes non-trivial correlations between jet and soft particle productions in small systems. We calibrate this framework with the final state hadrons' $p_T$-spectra from low to high $p_T$ in $p$-$p$, and and then compare with the spectra in $p$-$Pb$ collisions from the LHC. We also present results for additional observables such as the distributions of event activity as a function of the hardest jet $p_T$ in forward and mid-rapidity for both $p$-$p$ and $p$-$Pb$ collisions.

description: We present an analysis of the debris disc around the nearby K2 V star HIP 17439. In the context of the Herschel DUNES key programme the disc was observed and spatially resolved in the far-IR with the Herschel PACS and SPIRE instruments. In a first model, Ertel et al. (2014) assumed the size and radial distribution of the circumstellar dust to be independent power laws. There, by exploring a very broad range of possible model parameters several scenarios capable of explaining the observations were suggested. In this paper, we perform a follow-up in-depth collisional modelling of these scenarios trying to further distinguish between them. In our models we consider collisions, direct radiation pressure, and drag forces, i.e. the actual physical processes operating in debris discs. We find that all scenarios discussed in Ertel et al. are physically sensible and can reproduce the observed SED along with the PACS surface brightness profiles reasonably well. In one model, the dust is produced beyond 120au in a narrow planetesimal belt and is transported inwards by Poynting-Robertson and stellar wind drag. A good agreement with the observed radial profiles would require stellar winds by about an order of magnitude stronger than the solar value, which is not supported, although not ruled out, by observations. Another model consists of two spatially separated planetesimal belts, a warm inner and a cold outer one. This scenario would probably imply the presence of planets clearing the gap between the two components. Finally, we show qualitatively that the observations can be explained by assuming the dust is produced in a single, but broad planetesimal disc with a surface density of solids rising outwards, as expected for an extended disc that experiences a natural inside-out collisional depletion. Prospects of discriminating between the competing scenarios by future observations are discussed.

description: We have in a rat model studied the role of gastric neuroendocrine cells in the regulation of gastric function and growth and given indication for an important role of these cells in physiology and human carcinogenesis. Because of the high incidence of spontaneous tumors in the glandular stomach of mastomys (Praomys (mastomys) natalensis), we wanted to investigate if mastomys might be an useful model for our further studies. Tumors. were recognized in several organs of our mastomys, but not in the stomach. However, a high incidence oftrichobezoars was observed in the stomach and intestine, and obstruction from these was the cause of illness and death for many of them. Multiple factors are involved in the formation of bezoars. and these are discussed in relation to the occurrence in our mastomys colony.

description: The eigenvalues and eigenvectors of the matrix of coefficients of the linearized kinetic equations applied to aggregation in surfactant solution determine the full spectrum of characteristic times and specific modes of micellar relaxation. The dependence of these relaxation times and modes on the total surfactant concentration has been analyzed for concentrations in the vicinity and well above the second critical micelle concentration (cmc2) for systems with coexisting spherical and cylindrical micelles. The analysis has been done on the basis of a discrete form of the Becker-Doering kinetic equations employing the Smoluchowsky diffusion model for the attachment rates of surfactant monomers to surfactant aggregates with matching the rates for spherical aggregates and the rates for large cylindrical micelles. The equilibrium distribution of surfactant aggregates in solution has been modeled as having one maximum for monomers, another maximum for spherical micelles and wide slowly descending branch for cylindrical micelles. The results of computations have been compared with the analytical ones known in the limiting cases from solutions of the continuous Becker-Doering kinetic equation. They demonstrated a fair agreement even in the vicinity of the cmc2 where the analytical theory looses formally its applicability.

description: We develop a framework to understand the mechanics of metamaterial sheets on curved surfaces. Here we have constructed a continuum elastic theory of mechanical metamaterials by introducing an auxiliary, scalar gauge-like field that absorbs the strain along the soft mode and projects out the stiff ones. We propose a general form of the elastic energy of a mechanism based metamaterial sheet and specialize to the cases of dilational metamaterials and shear metamaterials conforming to positively and negatively curved substrates in the Föppl-Von Kármán limit of small strains. We perform numerical simulations of these systems and obtain good agreement with our analytical predictions. This work provides a framework that can be easily extended to explore non-linear soft modes in metamaterial elasticity in future.

description: A colony of Peruvian mice backerossed onto C3H/He mlee was found by serologieal testing to be infected with MHV. 10 male and 10 female mice of the most recent backcross generation were selected and tested for antibodies to MHV. Nineteen animals were serologically positive. These were passed into a positive pressure isolator via a Virkson bath. MFl sentinel mice in a second isolator unit were exposed to dirty litter from the backcress from day 13 onwards. Blood samples were taken from the sentinels on days 27, 34. 48 and 76. The backcross mice produced their first litter on day 43. No serocenversion occurred in the sentinel mice, or in offspring of the backcross. Animals from the original colony tested at the same age and time as the backeross oilspring had seroconverted to MHV.

description: The structures of multiply quantized vortices (MQVs) of an equal-population atomic Fermi superfluid in a rotating spherical bubble trap approximated as a thin shell are analyzed by solving the Bogoliubov-de Gennes (BdG) equation throughout the BCS-Bose Einstein condensation (BEC) crossover. Consistent with the Poincare-Hopf theorem, a pair of vortices emerge at the poles of the rotation axis in the presence of azimuthal symmetry, and the compact geometry provides confinement for the MQVs. While the single-vorticity vortex structure is similar to that in a planar geometry, higher-vorticity vortices exhibit interesting phenomena at the vortex center, such as a density peak due to accumulation of a normal Fermi gas and reversed circulation of current due to in-gap states carrying angular momentum, in the BCS regime but not the BEC regime because of the subtle relations between the order parameter and density. The energy spectrum shows the number of the in-gap state branches corresponds to the vorticity of a vortex, and an explanation based on a topological correspondence is provided.

description: Methods for euthanasia in laboratory animals should primarily be chosen with regard to animal welfare. safety of personnel and the purpose of the experiment, In the present study different killing techniques for guinea pigs, rats and mice were compared with regard to the animal response as well as post-mortem changes. Stunning by a blow to the back ofthe neck (guinea pigs), decapitation with guillotine (rats) and cervical dislocation (mice) werejudged to be followed by immediate unconsciousness rapidly followed by a cessation of breathing. If possible, animals should be sedated or lightly anaesthetized before euthanasia using a physical method. Physical methods induced local traumatic damage (neck, brain. meninges) as well as changes in the respiratory organs, especially the lungs (emphysema, bleeding. blood and fodder aspiration). Intraperitoneal overdose of pentobarbital (ISO mg/kg bw) was followed by a calm induction within 2—3 minutes and a cessation of breathing within 8—1 1 minutes. with considerable individual variation Morphologically, acute degenerative lesions in myocardial muscle cells and circulatory changes in the kidney cortex as well as limited lung changes were demonstrated in all species. Pure carbon dioxide in an equilibrated system induced unconsciousness within 10—20 see in rats and mice and within 40 sec. in guinea pigs, followed by rapid death. Rats especially showed a moderate uneasiness during the induction. All species developed lung emphysema while myocardial cell changes and extravasation to alveoli were found in guinea pigs and rats. Induction with (CO2/O2 (80:20) for 1 minute followed by pure CO; was judged to be the most humane method in all species from the animal welfare point of view. By adding oxygen the time for induction of unconsciousness was doubled in rats and mice but not much changed in guinea pigs. Breathmg ceased within 4 min in rats and mice and within 7 min in guinea pigs. In all specics this method induced lung oedema and considerable extravasation to ulveoli. This method cannot be recommended for studies including morphological investigations ofltmgs. From a strict animal welfare point of view the COQ/Oz-method is the most recommendable of the methods studied, followed by the pure CO2-method and next pentobarbital i/p. The equipment for inhalation euthanasia should be equilibrated With the actual gas or gas mixture before introduction ot'the animals. From the animal welfare point of view it is clear that the handling of the animals and technical efficiency of the person in charge are crucial factors for a good result. Ethically. all euthanasia techniques call for properly trained personnel and knowledge about post-mortem changes for an optimal scientific outcome.

description: Interacting systems of events may exhibit cascading behavior where events tend to be temporally clustered. While the cascades themselves may be obvious from the data, it is important to understand which states of the system trigger them. For this purpose, we propose a modeling framework based on continuous-time Bayesian networks (CTBNs) to analyze cascading behavior in complex systems. This framework allows us to describe how events propagate through the system and to identify likely sentry states, that is, system states that may lead to imminent cascading behavior. Moreover, CTBNs have a simple graphical representation and provide interpretable outputs, both of which are important when communicating with domain experts. We also develop new methods for knowledge extraction from CTBNs and we apply the proposed methodology to a data set of alarms in a large industrial system.

A Moments' Analysis of Quasi-Exactly Solvable Systems: A New Perspective on the Sextic Anharmonic and Bender-Dunne Potentials

description: There continues to be great interest in understanding quasi-exactly solvable (QES) systems. In one dimension, QES states assume the form $Ψ(x) =x^γP_d(x) {\cal A}(x)$, where ${\cal A}(x) > 0$ is known in closed form, and $P_d(x)$ is a polynomial to be determined. That is ${{Ψ(x)}\over {x^γ{\cal A}(x)}} = \sum_{n=0}^\infty a_nx^n$ truncates. The extension of this "truncation" procedure to non-QES states corresponds to the Hill determinant method, which is unstable when the {\it reference} function assumes the physical asymptotic form. Recently, Handy and Vrinceanu introduced the Orthogonal Polynomial Projection Quantization (OPPQ) method which has non of these problems, allowing for a unified analysis of QES and non-QES states. OPPQ uses a non-orthogonal basis constructed from the orthonormal polynomials of ${\cal A}$: $Ψ(x) = \sum_{j=0}^\infty Ω_j {\cal P}^{(j)}(x) {\cal A}(x)$, where $\langle {\cal P}^{(j_1)}|{\cal A}|{\cal P}^{(j_2)} \rangle = δ_{j_1,j_2}$, and $Ω_j = \langle {\cal P}^{(j)}|Ψ\rangle$. For systems admitting a moment equation representation, such as those considered here, these coefficients can be readily determined. The OPPQ quantization condition, $Ω_{j} = 0$, is exact for QES states (provided $j \geq d+1$); and is computationally stable, and exponentially convergent, for non-QES states. OPPQ provides an alternate explanation to the Bender-Dunne (BD) orthogonal polynomial formalism for identifying QES states: they correlate with an anomalous kink behavior in the order of the finite difference moment equation associated with the $Φ= x^γ{\cal A}(x) Ψ(x)$ {\it Bessis}-representation (i.e. a spontaneous change in the degrees of freedom of the system).

description: Regional blood peifusion. intraosseous pressure (IOP) and partial pressures of the intraosseous P02 and PCO2. were studied in the femoral bones of full grown minipigs. Half of the animals were treated with high, pulsed doses ot‘prednisone for 8 months, in order to examine the influence of corticosteroids on the bone blood flow, the IOP and the respiratory gases, and in an attempt to develop an animal model of steroid induced osteoneerosis. The regional perfusion of the femoral bones varied from 19.7 ml/100 g/min in the femoral neck to 1.1 ml/100 g/min in the diaphysis. The mean intraosseous pressure in the femoral head was 18.9 +/- 2.5 mmHg (mean : SEM) in the treated group and 16.2 +/- 1.4 mmllg in the controls (n.s.). The mean P02 in the femoral head was 52.1 +/- 2.7 mmHg and 54.2 : 3.2., respectively (11.5.) and PCO: was 39.2 +/- 1.9 mmllg and 44.5 +/- 1.2 (n.s.) Femoral head blood flow in the steroid treated animals was 13.4 +/- 2.1 ml/100 g/min and 14.3 +/- 1.0 ml/100g/min in controls. There was no difference in corresponding areas at the right and the left femoral bone, and no difference in any of the examined parameters in animals that had received steroids and those that had not. It is concluded, that a pronounced heterogeneity exists in the blood flow and in the intraosseous respiratory gases in the femoral bone, and that it is not possible to induce necrosis in the femoral head of minipigs by treating them with prednisone alone.

description: We demonstrate the fabrication of single-crystalline diamond nanopillars on a (111)-oriented chemical vapor deposited diamond substrate. This crystal orientation offers optimal coupling of nitrogen-vacancy (NV) center emission to the nanopillar mode and is thus advantageous over previous approaches. We characterize single native NV centers in these nanopillars and find one of the highest reported saturated fluorescence count rates in single crystalline diamond in excess of 10${}^6$ counts per second. We show that our nano-fabrication procedure conserves the preferential alignment as well as the spin coherence of the NVs in our structures. Our results will enable a new generation of highly sensitive probes for NV magnetometry and pave the way toward photonic crystals with optimal orientation of the NV center's emission dipole.
