description: Das Verhältnis zwischen Raumordnung und Verkehrspolitik ist vom Widerspruch zwischen langlebigen Siedlungsstrukturen und dynamisierenden Änderungen der Erreichbarkeitsverhältnisse geprägt. Damit stimulieren sich beide Bereiche, aber sind zugleich zur Partnerschaft verpflichtet. Für den Verkehrsplaner ist Raumordnung der wichtigste Gestaltungsbereich, um Verkehrswachstum großräumig zu vermeiden. Für die Raumordnung wiederum bildet der Verkehr die wichtigste Fachplanung, um funktionsfähige Raumstrukturen zu erhalten. Dieser Beitrag schildert die Tradition deutscher Raumordnung, Ziele und konkrete Aufgaben nach dem 2. Weltkrieg, den tiefgreifenden Strukturwandel beider Politikbereiche und ihre Herausforderungen durch deutsche Einheit, europäische Vernetzung und ökologische Neuorientierung.
description: The interrelationship between regional policy und transport policy is characterized by the contradiction between long-lasting setttlement structures and dynamising effects resulting from the changed degree and patterns of accessibility. The two fields stimulate each other but at the same time are obliged to cooperate. To transport planners regional policy is the most important political area of influence to restrict and channel traffic growth. For regional policy, on the other hand transport planning is the most influencial sector planning to ensure viable and effective spatial patterns. The paper describes the tradition of regional policy in Germany, its aims and concrete tasks after the war, the fundamental structural change in both fields and the challenge created by German unification, European integration and ecological reorientation.

description: This study compared the performance of seven gap-filling methods in daily streamflow and precipitation data and assessed the maximum number of gap days on which the methods perform well. Random (occurring randomly in the data series) and sequential (consecutive days with missing record) gaps were considered. Results show that the type of gaps affects the performance of the methods for gap-filling streamflow and precipitation data. Concerning random gaps, the best methods for streamflow were autoregressive integrate moving average and spline interpolation. For precipitation, the best methods were inverse distance weighting and linear regression (LR). Regarding sequential gaps, LR and multiple regression perform well in gap-filling up to 60 consecutive days in streamflow series. The other methods perform well up to 15 consecutive gap days. For precipitation series, the methods performed well up to seven consecutive missing days. For longer gaps (15, 30, 45 and 60 days), the methods performed poorly.

description: High-resolution galaxy spectra encode information about the stellar populations within galaxies. The properties of the stars, such as their ages, masses, and metallicities, provide insights into the underlying physical processes that drive the growth and transformation of galaxies over cosmic time.
 We explore a simulation-based inference (SBI) workflow to infer from optical absorption spectra the posterior distributions of metallicities and the star formation histories (SFHs) of galaxies (i.e. the star formation rate as a function of time).
 We generated a dataset of synthetic spectra to train and test our model using the spectroscopic predictions of the MILES stellar population library and non-parametric SFHs. We reliably estimate the mass assembly of an integrated stellar population with well-calibrated uncertainties. Specifically, we reach a score of $0.97\,R^2$ for the time at which a given galaxy from the test set formed $50\%$ of its stellar mass, obtaining samples of the posteriors in only $10^{-4}$\,s. We then applied the pipeline to real observations of massive elliptical galaxies, recovering the well-known relationship between the age and the velocity dispersion, and show that the most massive galaxies ($σ\sim300$ km/s) built up to 90\% of their total stellar masses within $1$\,Gyr of the Big Bang. The inferred properties also agree with the state-of-the-art inversion codes, but the inference is performed up to five orders of magnitude faster.
 This SBI approach coupled with machine learning and applied to full spectral fitting makes it possible to address large numbers of galaxies while performing a thick sampling of the posteriors. It will allow both the deterministic trends and the inherent uncertainties of the highly degenerated inversion problem to be estimated for large and complex upcoming spectroscopic surveys, such as DESI, WEAVE, or 4MOST.

description: We investigate the electronic and transport properties of gated bilayer graphene with one corrugated layer, which results in a stacking AB/BA boundary. When a gate voltage is applied to one layer, topologically protected gap states appear at the corrugation, which reveal as robust transport channels along the stacking boundary. With increasing size of the corrugation, more localized, quantum-well-like states emerge. These finite-size states are also conductive along the fold, but in contrast to the stacking boundary states, which are gapless, they present a gap. We have also studied periodic corrugations in bilayer graphene; our findings show that such corrugations between AB- and BA-stacked regions behave as conducting channels that can be easily identified by their shape.

description: We determine the contribution to the anomalous magnetic moment of the muon from the $α^2_{\mathrm{QED}}$ hadronic vacuum polarization diagram using full lattice QCD and including $u/d$ quarks with physical masses for the first time. We use gluon field configurations that include $u$, $d$, $s$ and $c$ quarks in the sea at multiple values of the lattice spacing, multiple $u/d$ masses and multiple volumes that allow us to include an analysis of finite-volume effects. We obtain a result for $a_μ^{\mathrm{HVP,LO}}$ of $667(6)(12)$, where the first error is from the lattice calculation and the second includes systematic errors from missing QED and isospin-breaking effects and from quark-line disconnected diagrams. Our result implies a discrepancy between the experimental determination of $a_μ$ and the Standard Model of 3$σ$.

description: Many time-dependent deformation processes at elevated temperatures produce significant concurrent microstructure changes that can alter the mechanical properties in a profound manner. Such microstructure evolution is usually absent in mesoscale deformation models and simulations. Here we present an integrated full-field modeling scheme that couples the mechanical response with the underlying microstructure evolution. As a first demonstration, we integrate a fast Fourier transform-based elasto-viscoplastic (FFT-EVP) model with a phase-field (PF) recrystallization model, and carry out three-dimensional (3D) simulations of dynamic recrystallization (DRX) in polycrystalline copper. A physics-based coupling between FFT-EVP and PF is achieved by (1) adopting a dislocation-based constitutive model in FFT-EVP, which allows the predicted dislocation density distribution to be converted to a stored energy distribution and passed to PF, and (2) implementing a stochastic nucleation model for DRX. Calibrated with the experimental DRX stress-strain curves, the integrated model is able to deliver full-field mechanical and microstructural information, from which quantitative description and analysis of DRX can be achieved. It is suggested that the initiation of DRX occurs significantly earlier than previous predictions, due to heterogeneous deformation. DRX grains are revealed to form at both grain boundaries and junctions (e.g., quadruple junctions) and tend to maintain a triple line with old grains during the growth. The resulted stress redistribution is found to have a profound influence on the subsequent dislocation evolution and the softening.

description: The accuracy of quantitative rainfall forecasts (QPFs) obtained from numerical weather prediction (NWP) models plays a crucial role in setting up a catchment streamflow forecasting system. Additionally, a suitable hydrological model is required. This study addresses input and model uncertainty in developing a five-day streamflow forecasting system in Narmada River Basin. We use deterministic and ensemble QPFs obtained from the Japan Meteorological Agency (JMA), National Centre for Medium Range Weather Forecasting (NCMRWF), and European Centre for Medium-Range Weather Forecasts (ECMWF). We use two hydrological models, the Soil and Water Assessment Tool (SWAT) and variable infiltration capacity (VIC), to generate streamflow forecasts. By comparing simulated streamflow forecasts with the observed discharge data, our results indicate that the forecast accuracy of NCMRWF is better than other forecasting products for lead times of two to five days. The streamflow generated using VIC produces better results than that obtained from the SWAT hydrological model.

description: Employee retention is a major problem for businesses of all sizes. While there are many factors that contribute to employee retention, compensation is one of the most important. This review article examines the research on the effectiveness of compensation in maintaining employee retention. The article begins by discussing the importance of compensation in employee retention. It then reviews the research on the determinants of employee retention and the impact of compensation on employee retention. The article concludes by discussing the implications of the research for organizations. The research reviewed in this article suggests that compensation is an important factor in employee retention. Studies have shown that compensation plays a significant role in employee retention. Employees who are paid more are more likely to stay with their organizations. However, it is clear that organizations must also focus on other factors beyond compensation, including job satisfaction, work-life balance, opportunities for career development, employee engagement, recognition, and communication also play a significant role in retaining employees. Furthermore, company culture, leadership, and other benefits can also affect employee retention. Organizations can improve their employee retention rates by offering competitive compensation packages. However, it is important to remember that compensation is not the only factor that affects employee retention. Organizations seeking to improve their employee retention rates should adopt a comprehensive approach that includes competitive compensation as well as addressing other factors important to employees that value and retains top talent, leading to long-term success and sustainability.

description: Current Event Stream Super-Resolution (ESR) methods overlook the redundant and complementary information present in positive and negative events within the event stream, employing a direct mixing approach for super-resolution, which may lead to detail loss and inefficiency. To address these issues, we propose an efficient Recursive Multi-Branch Information Fusion Network (RMFNet) that separates positive and negative events for complementary information extraction, followed by mutual supplementation and refinement. Particularly, we introduce Feature Fusion Modules (FFM) and Feature Exchange Modules (FEM). FFM is designed for the fusion of contextual information within neighboring event streams, leveraging the coupling relationship between positive and negative events to alleviate the misleading of noises in the respective branches. FEM efficiently promotes the fusion and exchange of information between positive and negative branches, enabling superior local information enhancement and global information complementation. Experimental results demonstrate that our approach achieves over 17% and 31% improvement on synthetic and real datasets, accompanied by a 2.3X acceleration. Furthermore, we evaluate our method on two downstream event-driven applications, \emph{i.e.}, object recognition and video reconstruction, achieving remarkable results that outperform existing methods. Our code and Supplementary Material are available at https://github.com/Lqm26/RMFNet.

description: The high-energy radiative output, from the X-ray to the ultraviolet, of exoplanet host stars drives photochemical reactions and mass loss in the upper regions of planetary atmospheres. In order to place constraints on the atmospheric properties of the three closest terrestrial exoplanets transiting M dwarfs, we observe the high-energy spectra of the host stars LTT1445A and GJ486 in the X-ray with XMM-Newton and Chandra and in the ultraviolet with HST/COS and STIS. We combine these observations with estimates of extreme ultraviolet flux, reconstructions of the Ly-a lines, and stellar models at optical and infrared wavelengths to produce panchromatic spectra from 1A--20um for each star. While LTT1445Ab, LTT1445Ac, and GJ486b do not possess primordial hydrogen-dominated atmospheres, we calculate that they are able to retain pure CO2 atmospheres if starting with 10, 15, and 50% of Earth's total CO2 budget, respectively, in the presence of their host stars' stellar wind. We use age-activity relationships to place lower limits of 2.2 and 6.6 Gyr on the ages of the host stars LTT1445A and GJ486. Despite both LTT1445A and GJ486 appearing inactive at optical wavelengths, we detect flares at ultraviolet and X-ray wavelengths for both stars. In particular, GJ486 exhibits two flares with absolute energies of 10^29.5 and 10^30.1 erg (equivalent durations of 4357+/-96 and 19724+/-169 s) occurring three hours apart, captured with HST/COS G130M. Based on the timing of the observations, we suggest that these high-energy flares are related and indicative of heightened flaring activity that lasts for a period of days, but our interpretations are limited by sparse time-sampling. Consistent high-energy monitoring is needed to determine the duration and extent of high-energy activity on individual M dwarfs, as well as the population as a whole.

description: The Tsallis distribution has been tested to fit the all particle spectra at mid-rapidity from central events produced in d+Au, Cu+Cu, Au+Au collisions at RHIC and p+Pb, Pb+Pb collisions at LHC. Even though there are strong medium effects in Cu+Cu and Au+Au collisions, the results show that the Tsallis distribution can be used to fit most of particle spectra in the collisions studied except in Au+Au collisions where some deviations are seen for proton and $Λ$ at low $p_T$. In addition, as the Tsallis distribution can only fit part of the particle spectra produced in Pb+Pb collisions where $p_T$ is up to 20 GeV/c, a new formula with one more fitting degree of freedom is proposed in order to reproduce the entire $p_T$ region.

description: This paper investigates the dynamics of cosmological models incorporating nonlinear electrodynamics (NLED), focusing on their stability and causality. We explore two specific NLED models: the Power-Law and Rational Lagrangians. We assess these models' viability in describing the universe's evolution using dynamical systems theory and Bayesian inference. We present the theoretical framework of NLED coupled with general relativity, followed by an analysis of the stability and causality through the squared sound speed of the NLED Lagrangians. We then conduct a detailed dynamical analysis to identify the universe's evolution with this matter content. Our results show that the Power-Law Lagrangian model transitions through various cosmological phases from a Maxwell radiation-dominated state to a matter-dominated state. For the Rational Lagrangian model, including the Maxwell term, stable and causal behavior is observed within specific parameter ranges, with critical points indicating the evolutionary pathways of the universe. To validate our theoretical findings, we perform Bayesian parameter estimation using a comprehensive set of observational data, including cosmic chronometers, Baryon Acoustic Oscillation (BAO) measurements, and Type Ia Supernovae (SNeIa). The estimated parameters for both models align with expected values for the current universe, particularly the matter density $Ω_m$ and the Hubble parameter $h$. However, the parameters $α$ and $b$ are not tightly constrained within the prior ranges. Our model comparison strongly favors the $Λ$CDM model over the NLED models for late-universe observations, as the NLED model does not exhibit a cosmological constant behavior. Our results highlight the need for further refinement and exploration of NLED-based cosmological models to fully integrate them into the standard cosmological framework.

description: Abstract  Global corporate operations have transformed due to AI integration. This revolution has significant challenges and great practices, like every other. Our article examines corporate AI adoption and implementation methods, highlighting the difficulty of this transformation. We work on governance measures that ensure AI's ethical use and regulatory compliance. A smooth AI  augmented transition requires change management. Employees, consumers, and regulators are crucial to this revolutionary path. Globally, we monitor AI adoption patterns across continents and economies. In the US, a powerhouse of innovation and diversity, AI faces a mass of laws and business uses. Canada and the UK prioritize ethical AI and data regulation. With government support and lots of data, China can dominate AI ethically. Japan uses AI in senior care, a novel technique given its aging population. We investigate beyond these global titans. We analyze the Philippines, a fast-changing economy influenced by AI. This country uses AI in banking, healthcare, and agriculture. AI chatbots increase banking customer service and innovative AI apps boost waste management. Equitable AI access and digital inclusion are the Philippines' specific issues. This report exposes the complex yet exciting environment of AI acceptance and implementation through meticulous research and nuanced review. It intends to educate companies and decision-makers about AI's issues and opportunities to foster ethical and effective AI growth and global industry improvement.  Keywords: Artificial Intelligence, AI Adoption, Implementation Strategies, Challenges, Best Practices, Governance, Change Management, Stakeholders, Global Economies, Philippines.

description: The recently reported compactified hyperboloidal method has found wide use in the numerical computation of quasinormal modes, with implications for fields as diverse as gravitational physics and optics. We extend this intrinsically relativistic method into the non-relativistic domain, demonstrating its use to calculate the quasinormal modes of the Schrödinger equation and solve related bound-state problems. We also describe how to further generalize this method, offering a perspective on the importance of non-relativistic quasinormal modes for the programme of black hole spectroscopy.

description: This chapter provides an introductory overview of the recent emergence of facial recognition technologies (FRTs) into everyday societal contexts and settings. As such, the chapter provides valuable social, political and economic context to the legal, ethical and regulatory issues that surround this fast-growing area of technology development. In particular, the chapter considers a range of emerging ‘pro-social’ applications of FRT that have begun to be introduced across various societal domains - from the application of FRTs in retail, entertainment, leisure and domestic contexts, through to the growing prevalence of 1:1 ID matching for intimate practices such as unlocking smartphones and other personal devices. In contrast to this seemingly steady acceptance and practical take-up of FRT throughout everyday life, the chapter makes a case for continuing to pay renewed attention to the everyday harms of these technologies in situ – most notably the harms associated with misrecognition of people’s presumed identities and/or mis-recognition of their inferred characteristics and attributes. All told, the chapter argues that FRT remains a technology that should not be considered as a benign addition to the current digital landscape. This remains technology that requires continued critical attention from scholars working in the social, cultural and legal domains.

description: North Carolina is home to the largest population of American Indians east of the Mississippi River, and the state with the seventh largest Indian population overall. Likewise, the nationwide Indian population is growing at a rate almost twice as fast as the U.S. average. Anticipating the needs of a growing population, it is important that public libraries in North Carolina provide Indian youth with books which provide culturally-affirming representations of Indian peoples, traditions, and histories.
For this study, the nine counties in North Carolina with the largest Indian populations were isolated using 2013 U.S. Census estimates. Then, utilizing the online public access catalogs of the public libraries serving those counties, bibliographic searches were conducted for a selection of 206 books recommended by professional reviewing authorities. The data indicate that less than a quarter of the selected titles have been collected by a majority of libraries in the subset.

description: We present evidence of Kelvin excitations in space-time resolved spectra of numerical simulations of quantum turbulence. Kelvin waves are transverse and circularly polarized waves that propagate along quantized vortices, for which the restitutive force is the tension of the vortex line, and which play an important role in theories of superfluid turbulence. We use the Gross-Pitaevskii equation to model quantum flows, letting an initial array of well-organized vortices develop into a turbulent bundle of intertwined vortex filaments. By achieving high spatial and temporal resolution we are able to calculate space-time resolved mass density and kinetic energy spectra. Evidence of Kelvin and sound waves is clear in both spectra. Identification of the waves allows us to extract the spatial spectrum of Kelvin waves, clarifying their role in the transfer of energy

description: CONTEXT: The spectral analysis of hot, massive stars is a fundamental astrophysical method to obtain their intrinsic properties and their feedback. Quantitative spectroscopy for hot, massive stars requires detailed numerical modeling of the atmosphere and an iterative treatment to obtain the best solution within a given framework. AIMS: We present an overview of different techniques for the quantitative spectroscopy of hot stars employed within the X-Shooting ULLYSES collaboration, from grid-based approaches to tailored fits. By performing a blind test, we gain an overview about the similarities and differences of the resulting parameters. Our study aims to provide an overview of the parameter spread caused by different approaches. METHODS: For three different stars from the sample (SMC O5 star AzV 377, LMC O7 star Sk -69 50, and LMC O9 star Sk -66 171), we employ different atmosphere codes (CMFGEN, Fastwind, PoWR) and strategies to determine their best-fitting model. For our analyses, UV and optical spectra are used to derive the properties with some methods relying purely on optical data for comparison. To determine the overall spectral energy distribution, we further employ additional photometry from the literature. RESULTS: Effective temperatures for each of three sample stars agree within 3 kK while the differences in log g can be up to 0.2 dex. Luminosity differences of up to 0.1 dex result from different reddening assumptions, which seem to be larger for the methods employing a genetic algorithm. All sample stars are nitrogen-enriched. CONCLUSIONS: We find a reasonable agreement between the different methods. Tailored fitting tends to be able to minimize discrepancies obtained with more course or automatized treatments. UV spectral data is essential for the determination of realistic wind parameters. For one target (Sk -69 50), we find clear indications of an evolved status.

description: Objective Physical education, physical activity and sports provision are important factors in whole school health promotion, however, a standardised evaluation framework to evaluate the contribution of these components is lacking. A framework that accounts for the distinct structures and associated factors, that impact upon provision would facilitate a more coherent evaluation. Methods A concept mapping methodology, involving the generation of factors relevant to school physical education, physical activity and sports provision and their subsequent thematic and numeric rating and sorting was utilised. Concept mapping effectively gathers, integrates, and visually and numerically represents the composite thinking of a group of relevant and expert stakeholders around a complex social phenomenon. Following a review of the extant literature and synthesis among 20 expert stakeholders, a list of 95 factor statements relevant to school physical education, physical activity and sports provision were developed. Results Each factor statement was rated and sorted by 197 multi-disciplinary participants. An eight-cluster framework that demonstrated good validity (stress value: 0.266), was derived from the data based on: 1. Partnerships and Pupil Centered Physical Education; 2. Physical Activity and Sports; 3. School Demographics; 4. Equipment, Facilities and Budget; 5. Extra Costs; 6. Curriculum and Policy; 7. School Management and 8. Timetable. Statements within the cluster on school management received the highest mean importance and modifiability ratings while statements within the cluster on school demographics received the low?est mean importance and modifiability ratings. Conclusions Eight overarching structures which account for school physical education, physical activity and sports provision have been identified. Within each of these, structures and overall factors of greatest importance and modifiability have been illuminated. Findings stemming from this rigorous methodology, provide the foundation for the development of a national provision evaluation index to inform both school-level and national policy and actions. It is recommended the current methodology is replicated in other nations to gain corresponding insights

description: A survey of academic reference librarians in North Carolina provided data for an examination of differences in survey administration on paper and the World Wide Web.  Research via the Internet is becoming more attractive for many researchers, but the effects of this medium upon research outcomes has been little explored.  This study examined in particular sampling and mode effects, and response rates of Web surveys.  The study found no sampling bias or mode effects in tests of the respondents' demographics and the content of responses.  Response rates to Web surveys are not as high as traditional survey methods, and while responses are gathered more quickly, the paper instrument was not far behind.  Email notices were more efficient for promoting the Web survey than paper notices.  Traditional postal surveys still hold some advantages over Web surveys.  Researchers must weigh the advantages in cost and speed to justify use of such instruments.
