description: We use a series of N-body/smoothed particle hydrodynamics simulations and analytic arguments to show that the presence of an effective temperature floor in the interstellar medium at T_F ~ 10^4 K naturally explains the tendency for low-mass galaxies to be more spheroidal, more gas rich, and less efficient in converting baryons into stars than larger galaxies. The trend arises because gas pressure support becomes important compared to angular momentum support in small dark matter haloes. We suggest that dwarf galaxies with rotational velocities ~ 40 km/s do not originate as thin discs, but rather are born as thick, puffy systems. If accreted on to larger haloes, tenuous dwarfs of this kind will be more susceptible to gas loss or tidal transformation than scaled-down versions of larger spirals. For a constant temperature floor, pressure support becomes less important in large haloes, and this produces a tendency for massive isolated galaxies to have thinner discs and more efficient star formation than their less massive counterparts, as observed.

description: We present a study of the relationships and environmental dependencies between stellar mass, star formation rate, and gas metallicity for more than 700 galaxies in groups up to redshift 0.35 from the Galaxy And Mass Assembly (GAMA) survey. To identify the main drivers, our sample was analyzed as a function of group-centric distance, projected galaxy number density, and stellar mass. By using control samples of more than 16000 star-forming field galaxies and volume limited samples, we find that the highest enhancement in SFR (0.3 dex) occurs in galaxies with the lowest local density. In contrast to previous work, our data show small enhancements of $\sim$0.1 dex in SFR for galaxies at the highest local densities or group-centric distances. Our data indicates quenching in SFR only for massive galaxies, suggesting that stellar mass might be the main driver of quenching processes for star forming galaxies. We can discard a morphological driven quenching, since the Sérsic index distribution for group and control galaxies are similar. The gas metallicity does not vary drastically. It increases $\sim$0.08 dex for galaxies at the highest local densities, and decreases for galaxies at the highest group-centric distances, in agreement with previous work. Altogether, the local density, rather than group-centric distance, shows the stronger impact in enhancing both, the SFR and gas metallicity. We applied the same methodology to galaxies from the IllustrisTNG simulations, and although we were able to reproduce the general observational trends, the differences between group and control samples only partially agree with the observations

description: Abstract: Large Language Models (LLMs) offer numerous applications, the full extent of which
is not yet understood. This paper investigates if LLMs can be applied for editing structured and
semi-structured documents with minimal effort. Using a qualitative research approach, we conduct
two case studies with ChatGPT and thoroughly analyze the results. Our experiments indicate that
LLMs can effectively edit structured and semi-structured documents when provided with basic,
straightforward prompts. ChatGPT demonstrates a strong ability to recognize and process the structure
of annotated documents. This suggests that explicitly structuring tasks and data in prompts might
enhance an LLM’s ability to understand and solve tasks. Furthermore, the experiments also reveal
impressive pattern matching skills in ChatGPT. This observation deserves further investigation, as it
may contribute to understanding the processes leading to hallucinations in LLMs.

description: We study the degeneracies between neutrino mass and dark energy as they manifest themselves in cosmological observations. In contradiction to a popular formula in the literature, the suppression of the matter power spectrum caused by massive neutrinos is not just a function of the ratio of neutrino to total mass densities f_nu=Omega_nu/Omega_m, but also each of the densities independently. We also present a fitting formula for the logarithmic growth factor of perturbations in a flat universe, f(z, k;f_nu,w,Omega_DE)= (1-A(k)*Omega_DE*f_nu+B(k)*f_nu^2-C(k)*f_nu^3)*Omega_m(z)^alpha, where alpha depends on the dark energy equation of state parameter w. We then discuss cosmological probes where the f factor directly appears: peculiar velocities, redshift distortion and the Intergrated Sachs-Wolfe effect. We also modify the approximation of Eisenstein & Hu (1999) for the power spectrum of fluctuations in the presence of massive neutrinos and provide a revised code (http://www.star.ucl.ac.uk/~lahav/nu_matter_power.f)

Nano-optical imaging of WS e2 waveguide modes revealing light-exciton interactions

Subjects: cond-mat.mes-hall

description: © 2016 American Physical Society. We report on a nano-optical imaging study of WSe2 thin flakes with scanning near-field optical microscopy (NSOM). The NSOM technique allows us to visualize in real space various waveguide photon modes inside WSe2. By tuning the excitation laser energy, we are able to map the entire dispersion of these waveguide modes both above and below the A exciton energy of WSe2. We found that all the modes interact strongly with WSe2 excitons. The outcome of the interaction is that the observed waveguide modes shift to higher momenta right below the A exciton energy. At higher energies, on the other hand, these modes are strongly damped due to adjacent B excitons or band-edge absorptions. The mode-shifting phenomena are consistent with polariton formation in WSe2.

description: We examine avalanche statistics of rain- and vibration-driven granular slides in miniature sand mounds. A crossover from power-law to non power-law avalanche-size statistics is demonstrated as a generic driving rate $ν$ is increased. For slowly-driven mounds, the tail of the avalanche-size distribution is a power-law with exponent $-1.97\pm 0.31$, reasonably close to the value previously reported for landslide volumes. The interevent occurrence times are also analyzed for slowly-driven mounds; its distribution exhibits a power-law with exponent $-2.670\pm 0.001$.

description: Personallose Selbstbedienungsshops im Einzelhandel sind im Vormarsch. Die Gründe hiefür sind vielfältig und aller Voraussicht nach auch im Zusammenhang mit Veränderungen, die durch die Pandemie ausgelöst wurden, zu sehen. Personalmangel, Schaffung von Möglichkeiten einer flexiblen, dezentralen und effizienten Versorgung wie auch Aspekte der Nachhaltigkeit können hierbei aufgezählt werden. Einen besonderen Stellenwert nimmt die Vermarktung regionaler Lebensmittelprodukte ein. Die Nähe zum Erzeuger, die Schaffung einer direkten Verkaufsmöglichkeit für die Produzenten unter Ausschluss komplexer Handelsketten, Aspekte der Frische und insbesondere eines umweltgerechten Handelns stellen wesentliche Treiber dar. Beinahe zwingend ergibt sich hieraus, dass dies mittels kleinerer, dezentraler Verkaufseinheiten umgesetzt werden kann. Dem entgegen stehen Kosten der zu schaffenden Infrastruktur und für den Betrieb, die schlussendlich aus Effizienzgründen den Einsatz digitaler Technologien erfordern. So müssen zur Schaffung der Betriebsfähigkeit einfache, sichere Kassensysteme zum Einsatz kommen, Überwachungssysteme aus Gründen der Sicherheit und zur Missbrauchsreduzierung, aber auch autarke, smarte Energieversorgungssysteme. Weniger Augenmerk wurde bis dato auf den Einsatz digitaler Technologien zur Verbesserung der sogenannten Customer Experience gelegt. Im Rahmen dieser Arbeit soll ein Versuchsfeld (Living-lab) geschaffen werden, um Chancen, Risiken und Handlungsempfehlungen für den Einsatz generativer KI-Techniken innerhalb sogenannter Micro-shops zu untersuchen. Primär sollen hierbei einfache bis hin zu multimediale ChatBot-Systeme zum Einsatz kommen, mit dem primären Ziel, das Einkaufserlebnis der Kund:innen zu steigern. Das sekundäre Ziel besteht darin, einen effizienteren Betrieb dieser Verkaufsformen sicherzustellen.
Depth-Resolved Composition and Electronic Structure of Buried Layers and Interfaces in a LaNiO3/SrTiO3 Superlattice from Soft- and Hard- X-ray Standing-Wave Angle-Resolved Photoemission

description: © 2016 Elsevier B.V. LaNiO3 (LNO) is an intriguing member of the rare-earth nickelates in exhibiting a metal-insulator transition for a critical film thickness of about 4 unit cells [Son et al., Appl. Phys. Lett. 96, 062114 (2010)]; however, such thin films also show a transition to a metallic state in superlattices with SrTiO3 (STO) [Son et al., Appl. Phys. Lett. 97, 202109 (2010)]. In order to better understand this transition, we have studied a strained LNO/STO superlattice with 10 repeats of [4 unit-cell LNO/3 unit-cell STO] grown on an (LaAlO3)0.3(Sr2AlTaO6)0.7 substrate using soft x-ray standing-wave-excited angle-resolved photoemission (SWARPES), together with soft- and hard- x-ray photoemission measurements of core levels and densities-of-states valence spectra. The experimental results are compared with state-of-the-art density functional theory (DFT) calculations of band structures and densities of states. Using core-level rocking curves and x-ray optical modeling to assess the position of the standing wave, SWARPES measurements are carried out for various incidence angles and used to determine interface-specific changes in momentum-resolved electronic structure. We further show that the momentum-resolved behavior of the Ni 3d eg and t2g states near the Fermi level, as well as those at the bottom of the valence bands, is very similar to recently published SWARPES results for a related La0.7Sr0.3MnO3/SrTiO3 superlattice that was studied using the same technique (Gray et al., Europhysics Letters 104, 17004 (2013)), which further validates this experimental approach and our conclusions. Our conclusions are also supported in several ways by comparison to DFT calculations for the parent materials and the superlattice, including layer-resolved density-of-states results.

description: We investigate halo mass selection properties of red-sequence cluster finders using galaxy populations of the Millennium Simulation (MS). A clear red sequence exists for MS galaxies in massive halos at redshifts z < 1, and we use this knowledge to inform a cluster-finding algorithm applied to 500 Mpc/h projections of the simulated volume. At low redshift (z=0.4), we find that 90% of the clusters found have galaxy membership dominated by a single, real-space halo, and that 10% are blended systems for which no single halo contributes a majority of a cluster's membership. At z=1, the fraction of blends increases to 22%, as weaker redshift evolution in observed color extends the comoving length probed by a fixed range of color. Other factors contributing to the increased blending at high-z include broadening of the red sequence and confusion from a larger number of intermediate mass halos hosting bright red galaxies of magnitude similar to those in higher mass halos. Our method produces catalogs of cluster candidates whose halo mass selection function, p(M|\Ngal,z), is characterized by a bimodal log-normal model with a dominant component that reproduces well the real-space distribution, and a redshift-dependent tail that is broader and displaced by a factor ~2 lower in mass. We discuss implications for X-ray properties of optically selected clusters and offer ideas for improving both mock catalogs and cluster-finding in future surveys.

description: © 2016 American Physical Society. We present measurements of the near side of triggered di-hadron correlations using neutral strange baryons (Λ,Λ) and mesons (KS0) at intermediate transverse momentum (3 < pT <6 GeV/c) to look for possible flavor and baryon-meson dependence. This study is performed in d+Au, Cu+Cu, and Au+Au collisions at sNN=200 GeV measured by the STAR experiment at RHIC. The near-side di-hadron correlation contains two structures, a peak which is narrow in azimuth and pseudorapidity consistent with correlations from jet fragmentation, and a correlation in azimuth which is broad in pseudorapidity. The particle composition of the jet-like correlation is determined using identified associated particles. The dependence of the conditional yield of the jet-like correlation on the trigger particle momentum, associated particle momentum, and centrality for correlations with unidentified trigger particles are presented. The neutral strange particle composition in jet-like correlations with unidentified charged particle triggers is not well described by PYTHIA. However, the yield of unidentified particles in jet-like correlations with neutral strange particle triggers is described reasonably well by the same model.

description: Companies face major challenges when it comes to developing a strategic approach related to artificial intelligence (AI). The massive wave of generative models that has just started is another indication that technology adaptation is associated with very large uncertainties. As a result, a large number of undirected activities in corporates occur in which so-called use cases, prototypes and minimum viable products are implemented. A targeted and strategic approach is hardly recognizable. The aim of the work carried out here was to develop a practical model that meets all parameters: moving forward quickly, learning from mistakes, developing unique selling points and thus competitive advantages ultimately resulting in an AI strategy. This is exactly what can be achieved in 3 steps, the efficiency phase, the competitive advantage phase and the transformation phase, all of which build on one another sequentially. The model presented here also makes a significant contribution to the development and adaptation of a responsible AI.

As a by-product we obtain a closed formula for the fundamental solution to the discrete Laplacian. For the proofs we express the resolvent in a general dimension in terms of the Appell--Lauricella hypergeometric function of type $C$ outside a disk encircling the spectrum. In low dimensions it reduces to a generalized hypergeometric function, for which certain transformation formulas are available for the desired expansions.

description: © 2015. There are languages A such that there is a Pushdown Automata (PDA) that recognizes A which is much smaller than any Deterministic Pushdown Automata (DPDA) that recognizes A. There are languages A such that there is a Linear Bounded Automata (Linear Space Turing Machine, henceforth LBA) that recognizes A which is much smaller than any PDA that recognizes A. There are languages A such that both A and A are recognizable by a PDA, but the PDA for A is much smaller than the PDA for A. There are languages A1, A2 such that A1, A2, A1∩A2 are recognizable by a PDA, but the PDA for A1 and A2 are much smaller than the PDA for A1∩A2. We investigate these phenomena and show that, in all these cases, the size difference is captured by a function whose Turing degree is on the second level of the arithmetic hierarchy.Our theorems lead to infinitely-many-n results. For example: for-infinitely-many-n there exists a language An recognized by a DPDA such that there is a small PDA for An, but any DPDA for An is very large. We look at cases where we can get all-but-a-finite-number-of-n results, though with much smaller size differences.

description: Runtime monitoring is generally considered a light-weight alternative to formal verification. In safety-critical systems, however, the monitor itself is a critical component. For example, if the monitor is responsible for initiating emergency protocols, as proposed in a recent aviation standard, then the safety of the entire system critically depends on guarantees of the correctness of the monitor. In this paper, we present a verification extension to the Lola monitoring language that integrates the efficient specification of the monitor with Hoare-style annotations that guarantee the correctness of the monitor specification. We add two new operators, assume and assert, which specify assumptions of the monitor and expectations on its output, respectively. The validity of the annotations is established by an integrated SMT solver. We report on experience in applying the approach to specifications from the avionics domain, where the annotation with assumptions and assertions has lead to the discovery of safety-critical errors in the specifications. The errors range from incorrect default values in offset computations to complex algorithmic errors that result in unexpected temporal patterns.

description: Part of a collection of correspondence from Kathleen Raine to Robin Skelton. Skelton was a British poet, academic, anthologist, and practicing Wiccan. He taught at Manchester University before emigrating to Canada in 1963, where he taught creative writing at the University of Victoria and started the literary magazine The Malahat Review. Also included are some letters to Skelton’s wife Sylvia, and his daughters. Spanning close to forty-five years, the correspondence discusses poetry, writing, and philosophy; particularly Platonism and Neoplatonism. Raine often refers to the writings of William Blake and W. B. Yeats. Many letters also mention contemporary literary figures at the time including: Herbert Read, Peter Russell, Liam Miller, and Thurairajah Tambimuttu. In this letter, Raine explains why she does not wish for her work to be anthologised, David Gascoyne, her daughter Anna's writing, and extending her time in academia at Cambridge.

Parametrizing Shimura subvarieties of A 1 Shimura varieties and related geometric problems

Shimura variety

description: © 2016, Springer International Publishing. This paper gives a complete parametrization of the commensurability classes of totally geodesic subspaces of irreducible arithmetic quotients of Xa,b=(H2)a×(H3)b. A special case describes all Shimura subvarieties of type A 1 Shimura varieties. We produce, for any n≥ 1 , examples of manifolds/Shimura varieties with precisely n commensurability classes of totally geodesic submanifolds/Shimura subvarieties. This is in stark contrast with the previously studied cases of arithmetic hyperbolic 3-manifolds and quaternionic Shimura surfaces, where the presence of one commensurability class of geodesic submanifolds implies the existence of infinitely many classes.

subject: process mining simulation

description: Ever-evolving business processes can be re-engineered with process mining and simulation as a technology, as the approach shapes future outcomes, analyzing their present and past. Developing effective models can make it easier and more cost-effective, as there are potential benefits such as working with what-if scenarios and eliminating bottlenecks, but their quality check is always an issue. Different criteria have been applied to tackle this quality issue, disclosing expected benefits and weaknesses. This can help build suitable ground for analyzing and implementing relevant use cases. The criteria extracted from process model quality research demonstrate the effectiveness of model assessment and have practical implications for improving use case modeling. Results display the quality of particular models and indicate how use case modeling can be improved.

description: © 2016, Science China Press and Springer-Verlag Berlin Heidelberg. It has been shown that analog-to-information conversion (AIC) is an efficient scheme to perform sub-Nyquist sampling of pulsed radar echoes. However, it is often impractical, if not infeasible, to reconstruct full-range Nyquist samples because of huge storage and computational load requirements. Based on the analyses of AIC measurement system, this paper develops a novel segment-sliding reconstruction (SegSR) scheme to effectively reconstruct the Nyquist samples. The SegSR performs segment-by-segment reconstruction in a sliding mode and can be implemented in real time. An important characteristic that distinguishes the proposed SegSR from existing methods is that the measurement matrix in each segment satisfies the restricted isometry property (RIP) condition. Partial support in the previous segment can be incorporated into the estimation of the Nyquist samples in the current segment. The effect of interference introduced from adjacent segments is theoretically analyzed, and it is revealed that the interference consists of two interference levels with different impacts to the signal reconstruction performance. With these observations, a two-step orthogonal matching pursuit (OMP) procedure is proposed for segment reconstruction, which takes into account different interference levels and partially known support of the previous segment. The proposed SegSR scheme achieves near-optimal reconstruction performance with a significant reduction of computational loads and storage requirements. Theoretical analyses and simulations verify its effectiveness.
Breakdown of the adiabatic limit in low dimensional gapless systems

description: It is generally believed that a generic system can be reversibly transformed from one state into another by sufficiently slow change of parameters. A standard argument favoring this assertion is based on a possibility to expand the energy or the entropy of the system into the Taylor series in the ramp speed. Here we show that this argumentation is only valid in high enough dimensions and can break down in low-dimensional gapless systems. We identify three generic regimes of a system response to a slow ramp: (A) mean-field, (B) non-analytic, and (C) non-adiabatic. In the last regime the limits of the ramp speed going to zero and the system size going to infinity do not commute and the adiabatic process does not exist in the thermodynamic limit. We support our results by numerical simulations. Our findings can be relevant to condensed-matter, atomic physics, quantum computing, quantum optics, cosmology and others.

PARLIAMENTARY SOVEREIGNTY AND CONSTITUTIONAL SUPREMACY: A UK-INDIA COMPARATIVE PERSPECTIVE
Creators: name: Dr. Goutam Banerjee
Publisher: name: Zenodo
Year: 2025

description: This study critically investigates the evolving dynamics between parliamentary sovereignty and constitutional supremacy in the UK and India from 2020 to 2024, addressing a pressing need to understand constitutional resilience amid rising legislative dominance. With growing concerns over democratic backsliding, the research aims to assess how these two contrasting legal systems manage the tension between legislative autonomy and constitutional accountability. Utilizing a qualitative-comparative methodology grounded in secondary data-including 40+ scholarly works, government reports, and judicial records-the study combines thematic analysis with statistical techniques such as paired and independent t-tests, regression modeling, and correlation analysis. Major findings reveal a 14-point decline in UK public trust (from 60% to 46%) and a 15-point fall in India’s judicial independence (from 68% to 53%), alongside a rise in legislative dominance (UK: +34 points; India: constant at 76%). Statistical results include a strong negative correlation between legislative dominance and institutional autonomy (r = -0.92), and a regression model explaining 86% of variance in institutional resilience. Conclusions highlight converging erosion of constitutional safeguards despite differing traditions, confirming that codified or uncodified structures alone are insufficient. The study recommends enhanced legislative scrutiny, judicial reform, and creation of transnational oversight mechanisms. Findings have global implications for reinforcing democratic governance and checking legislative overreach.
Recent Advances in Leveraging Human Guidance for Sequential Decision-Making Tasks

description: A longstanding goal of artificial intelligence is to create artificial agents capable of learning to perform tasks that require sequential decision making. Importantly, while it is the artificial agent that learns and acts, it is still up to humans to specify the particular task to be performed. Classical task-specification approaches typically involve humans providing stationary reward functions or explicit demonstrations of the desired tasks. However, there has recently been a great deal of research energy invested in exploring alternative ways in which humans may guide learning agents that may, e.g., be more suitable for certain tasks or require less human effort. This survey provides a high-level overview of five recent machine learning frameworks that primarily rely on human guidance apart from pre-specified reward functions or conventional, step-by-step action demonstrations. We review the motivation, assumptions, and implementation of each framework, and we discuss possible future research directions.

description: We say that an algebra A is periodic if it has a periodic projective resolution as an (A,A)-bimodule. We show that any self-injective algebra of finite representation type is periodic. To prove this, we first apply the theory of smash products to show that for a finite Galois covering B --> A, B is periodic if and only if A is. In addition, when A has finite representation type, we build upon results of Buchweitz to show that periodicity passes between A and its stable Auslander algebra. Finally, we use Asashiba's classification of the derived equivalence classes of self-injective algebras of finite type to compute bounds for the periods of these algebras, and give an application to stable Calabi-Yau dimensions.
