description: Introduction: This paper describes the nurses' perception of their leader's transformational leadership and how it reflects on their work engagement, and whether this prevents nurses' workforce depreciation for a foreseeable time.
 Methods: The study uses a descriptive correlational quantitative research design. Respondents are staff nurses (N=134) selected using probability stratified random sampling—use of adopted survey questionnaire, Multifactorial Leadership questionnaire rater form, and Work and well-being survey form. Statistical analyses were mean, percentage, standard deviation, t-test, Pearson correlation, Chi-square test, Kendal tau, and Spearman’s rho.
 Results: The study revealed that there is a positive relationship between the perceived three transformational leadership dimensions with nurses' work engagement, in contrast, intellectual stimulation has no significant relationship with work engagement. The demographic profile of nurses in terms of educational attainment and years of service has no significant relationship with the level of their work engagement in contrary to nurses’ age and gender characteristics.
 Discussion: Although the respondents perceived their leaders sometimes use the transformational leadership style and experienced physical and mental health challenges, nurses-maintained resilience to establish work engagement. The study recommends maintaining and practicing more transformational leadership training, such as shared governance activities and a reward system that boosts employee morale and engagement. A positive manager-employee relationship will help create a safe, healthy, and supportive work climate that leads to patient safety and care services satisfaction.

description: Massive spectroscopic survey are becoming trendy in astrophysics and cosmology, as they can address new fundamental knowledge such as Galactic Archaeology and probe the nature of the mysterious Dark Energy. To enable massive spectroscopic surveys, new technology are being developed to place thousands of optical fibers at a given position on a focal plane. These technology needs to be: 1) accurate, with micrometer positional accuracy; 2) fast to minimize overhead; 3) robust to minimize failure; and 4) low cost. In this paper we present the development of a new 8-mm in diameter fiber positionner robot using two 4mm DC-brushless gearmotors, developed in the context of the Dark Energy Spectroscopic Instrument. This development was conducted by a Spanish-Swiss (ES-CH) team led by the Instituto de Física Teórica (UAM-CSIC) and the Laboratoire d'Astrophysique (EPFL), in collaboration with the AVS company in Spain and the Faulhaber group (MPS & FAULHABER-MINIMOTOR) in Switzerland.

Parity-violating primordial gravitational waves from null energy condition violation

description: We investigate the parity-violating effects in primordial gravitational waves (GWs) due to null energy condition (NEC) violation in two very early universe scenarios: bounce-inflation and intermediate NEC violation during inflation. In both scenarios, we numerically solve the power spectra of parity-violating primordial GWs generated by coupling the background field and the spectator field with the Nieh-Yan term, respectively. We find that the background field can significantly enhance parity-violating effects at scales corresponding to the maximum of the GW power spectra. In contrast, the parity-violating effects produced by the spectator show significantly weaker observability even if the coupling constant is large. Therefore, in NEC-violating scenarios, the significant observable parity-violating effects in primordial GWs primarily arise from the physics directly related to NEC violation. This result highlights the potential of primordial GWs as crucial tools for exploring NEC-violating and parity-violating physics.

A pressure correction scheme for generalized form of energy-stable open boundary conditions for incompressible flows

description: We present a generalized form of open boundary conditions, and an associated numerical algorithm, for simulating incompressible flows involving open or outflow boundaries. The generalized form represents a family of open boundary conditions, which all ensure the energy stability of the system, even in situations where strong vortices or backflows occur at the open/outflow boundaries. Our numerical algorithm for treating these open boundary conditions is based on a rotational pressure correction-type strategy, with a formulation suitable for $C^0$ spectral-element spatial discretizations. We have introduced a discrete equation and associated boundary conditions for an auxiliary variable. The algorithm contains constructions that prevent a numerical locking at the open/outflow boundary. In addition, we have also developed a scheme with a provable unconditional stability for a sub-class of the open boundary conditions. Extensive numerical experiments have been presented to demonstrate the performance of our method for several flow problems involving open/outflow boundaries. We compare simulation results with the experimental data to demonstrate the accuracy of our algorithm. Long-time simulations have been performed for a range of Reynolds numbers at which strong vortices or backflows occur at the open/outflow boundaries. We show that the open boundary conditions and the numerical algorithm developed herein produce stable simulations in such situations.

description: We present Very Large Array observations at 7 mm that trace the thermal emission of large dust grains in the HD 169142 protoplanetary disk. Our images show a ring of enhanced emission of radius ~25-30 AU, whose inner region is devoid of detectable 7 mm emission. We interpret this ring as tracing the rim of an inner cavity or gap, possibly created by a planet or a substellar companion. The ring appears asymmetric, with the western part significantly brighter than the eastern one. This azimuthal asymmetry is reminiscent of the lopsided structures that are expected to be produced as a consequence of trapping of large dust grains. Our observations also reveal an outer annular gap at radii from ~40 to ~70 AU. Unlike other sources, the radii of the inner cavity, the ring, and the outer gap observed in the 7 mm images, which trace preferentially the distribution of large (mm/cm sized) dust grains, coincide with those obtained from a previous near-infrared polarimetric image, which traces scattered light from small (micron- sized) dust grains. We model the broad-band spectral energy distribution and the 7 mm images to constrain the disk physical structure. From this modeling we infer the presence of a small (radius ~0.6 AU) residual disk inside the central cavity, indicating that the HD 169142 disk is a pre-transitional disk. The distribution of dust in three annuli with gaps in between them suggests that the disk in HD 169142 is being disrupted by at least two planets or substellar objects.

J. S. Bachs Kanonische Veränderungen über "Vom Himmel hoch" (BWV 769)

description: Die Versuche der Forschung, zu einem eindeutigen Ergebnis in der Frage zu kommen, welche der beiden Hauptquellen, der Originaldruck Q oder die autographe Reinschrift A, die Fassung letzter Hand darstellt, stellen ein irreführendes Unternehmen dar. Beide Quellen sind vielschichtige Komplexe, deren Beziehungen zueinander sich in jedem Stadium ihrer mitunter verworrenen Entstehungsgeschichte anders gestalten. Auf die kanonischen Veränderungen 'Vom Himmel hoch' BWV 769 ist das Konzept einer Fassung letzer Hand überhaupt nicht anwendbar, ja es erweist sich sogar als für das Verständnis des Werkes kontraproduktiv.

description: The Bell-CHSH (Clauser-Horne-Shimony-Holt) inequality in the vacuum state of a relativistic scalar quantum field is analyzed. Using Weyl operators built with smeared fields localized in the Rindler wedges, the Bell-CHSH inequality is expressed in terms of the Lorentz invariant inner products of test functions. A numerical framework for these inner products is devised. Causality is also explicitly checked by a numerical evaluation of the Pauli-Jordan function. Violations of the Bell-CHSH inequality are reported for different values of the particle mass parameter.

Reliability of concrete slabs subjected to a natural fire designed by tabulated values

Fire safety engineering

description: The design check regarding the fire resistance of concrete slabs can be easily performed using tabulated values. Design codes specify the minimum thickness and minimum axis distance for the desired fire rating. The tables are based on experimental results and are well accepted by engineers and building authorities. However, the actual level of safety of the structural components, that is obtained by this approach, is not known. On the other hand, performance-based methods are more accepted, but require a target reliability as performance criterion. Hence there is a need for calibration of the performance methods using the results of the “traditional” descriptive approach. The calibration is performed for a single span concrete slab, where the axis distance of the reinforcement is chosen in order to meet the design requirements for a fire rating R30 and R90. A “standard” compartment is selected to cover typical fields of application. The opening factor is considered as parameter to obtain the maximum peak temperatures in the compartment. The stochastic basic variables are identified and a Monte-Carlo simulation is set up to calculate the probabilities of failure. The results indicate that the calculated reliability index is within the range, which has been used for the derivation of safety and combination factors in the Eurocodes. It can be observed that members designed for a fire rating R90 have a significant increase of the structural safety compared to a design for a fire rating R30.

description: Numerical studies on the imaging and caustic properties of the singular isothermal sphere (SIS) under a wide range of external shear (from 0.0 to 2.0) are presented. Using a direct inverse-mapping formula for this lens system (Lee 2003), we investigate various lensing properties under both a low (i.e., γ < 1.0), and a high (i.e., γ > 1.0) shear case: image separations, total or individual magnifications, flux ratios of 2-images, maximum number of images, and lensing cross-sections. We systematically analyze the effective lensing cross-sections of double-lensing and quad-lensing systems based on the radio luminosity function obtained by Jodrell-VLA Astrometric Survey (JVAS) and Cosmic Lens ALL-Sky Survey (CLASS). We find that the limit of a survey selection bias (i.e., between a brighter- and a fainter-image) preferentially reduces the effective lensing cross-sections of 2-image lensing systems. By considering the effects of survey selection bias, we demonstrate that the long standing anomaly on the high Quads-to-Doubles ratios (i.e., JVAS & CLASS: 50% ~ 70%) can be explained by the moderate effective shear of 0.16 ~ 0.18, which is half of previous estimates. The derived inverse mapping formula could facilitate the SIS + shear lens model to be useful for galaxy-lensing simulations. *Key-words: Cosmology; Theory; Gravitational lens; Strong.

description: We review the consequences of intrinsic frustration of the orbital superexchange and of spin-orbital entanglement. While Heisenberg perturbing interactions remove frustration in the compass model, the lowest columnar excitations are robust in the nanoscopic compass clusters and might be used for quantum computations. Entangled spin-orbital states determine the ground states in some cases, while in others concern excited states and lead to measurable consequences, as in the $R$VO$_3$ perovskites. On-site entanglement for strong spin-orbit coupling generates the frustrated Kitaev-Heisenberg model with a rich magnetic phase diagram on the honeycomb lattice. Frustration is here reflected in hole propagation which changes from coherent in an antiferromagnet via hidden quasiparticles in zigzag and stripe phases to entirely incoherent one in the Kitaev spin liquid.

Die Zuschreibung an Heinichen geht auf Philipp Spitta zurück. Ihr wird anhand der Geschichte der acht vorhandenen Handschriften des Werks widersprochen, deren Abhängigkeitsverhältnisse und Geschichte untersucht werden: Spittas Fehlzuschreibung beruht demzufolge auf dem engen Nebeneinander verschiedener überlieferter Stücke in der Quelle P 303, das den Irrtum ermöglichte, während sieben andere Quellen eindeutig Bach als Autor angeben. Es schließen sich Ausführungen über das Motiv des Labyrinths in der Vorstellungswelt vom Mittelalter bis zum Barock an.

Eintragungen Altnickols in Original-MS Bachs zeigen, dass er als Organist der Naumburger Wenzelskirche Zugang zu Werken seines Lehrers hatte und diese auch praktisch nutzte (zum Beispiel BWV 120 und BWV 197). Zahlreiche weitere Werke Bachs finden sich in einem Choralbuch, das Altnickols Nachfolger Johann Christoph Gräbner (gestorben 1794) um 1760 anlegte. In den weiteren Zusammenhang der Naumburger Bach-Überlieferung gehört schließlich auch die einzige bekannte Quelle zu Johann Adam Reinckens Choralbearbeitung 'An Wasserflüssen Babylon'.

Anhand eines Kriterienkatalogs konnten über 20 Instrumente des älteren Typs, sogar bisher unbekannte Tenor-Instrumente, identifiziert werden. Ein großer Teil des historischen Repertoires, etwa aus Hamburg, Darmstadt und Mitteldeutschland, wurde auf solchen Instrumenten gespielt. Charakteristisch sind eine unspezifische Stimmführung und improvisierte Akkorde. (Autor, Quelle: Bibliographie des Musikschrifttums online)

description: Two-dimensional atomic crystals are extensively studied in recent years due to their exciting physics and device applications. However, a molecular counterpart, with scalable processability and competitive device performance, is still challenging. Here, we demonstrate that high-quality few-layer dioctylbenzothienobenzothiophene molecular crystals can be grown on graphene or boron nitride substrate via van der Waals epitaxy, with precisely controlled thickness down to monolayer, large-area single crystal, low process temperature and patterning capability. The crystalline layers are atomically smooth and effectively decoupled from the substrate due to weak van der Waals interactions, affording a pristine interface for high-performance organic transistors. As a result, monolayer dioctylbenzothienobenzothiophene molecular crystal field-effect transistors on boron nitride show record-high carrier mobility up to 10cm2V-1s-1 and aggressively scaled saturation voltage around 1V. Our work unveils an exciting new class of two-dimensional molecular materials for electronic and optoelectronic applications.

description: Despite the remarkable progress in emerging solar cell technologies such as hybrid organic-inorganic perovskites, there are still significant limitations related to the stability of the devices and their non-ideal electrical behavior under certain external stimuli. We present a conceptual framework for characterizing photovoltaic devices by integrating cyclic voltammetry (CV) and impedance spectroscopy (IS). This framework is constructed from a microscopic, multi-mode perspective that explicitly accounts for drift, diffusion, displacement, and memory contributions. We derive comprehensive analytical expressions for current-voltage relationships and complex admittance. Our model reveals the inseparable connection between hysteresis behaviors in current-voltage characteristics observed in CV and the apparent capacitive and inductive behaviors seen in IS spectral analysis. We demonstrate how CV and IS naturally complement each other, providing a deeper microscopic understanding of device performance and limitations. Additionally, we establish the relationship between intrinsic material parameters and experimentally accessible extrinsic parameters such as light intensity, temperature, DC bias, voltage amplitude, and frequency. This framework enables unprecedented optimization of solar cell performance, marking a significant advancement towards sustainability.

description: The original shipping strategy of FedEx is to fly all packages to a hub location during the afternoon and evening, sort them there, and then fly them to their destinations during the night for delivery the next day. This leads to interesting mathematical questions: Given a population represented by points in Euclidean space or on a sphere, what is the location of the point of the hub that minimizes the total distance to all the points? Is such a point unique? Then using census data from 2000 we examine how close the FedEx hub in Memphis is to the hub for the U.S. population.

description: 2015 marked the 90th anniversary of the description of the first fossil ofAustralopithecus africanus, commonly known as the Taung Child, which was unearthed during blasting at the Buxton-Norlim Limeworks (referred to as the BNL) 15 km SE of the town of Taung, South Africa. Subsequently, this site has been recognized as a UNESCOWorld Heritage site on the basis of its importance to southern African palaeoanthropology. Some other sites such as Equus Cave and Black Earth Cave have also been investigated; but the latter not since the 1940s. These sites indicate that the complex of palaeontological and archaeological localities at the BNL preserve a time sequence spanning the Pliocene to the Holocene. The relationship of these various sites and how they fit into the sequence of formation of tufa, landscapes and caves at the limeworks have also not been investigated or discussed in detail since Peabody’s efforts in the 1940s. In this contribution we mark the 90th anniversary of the discovery and description of the Taung Child by providing a critical review of previous work at Taung based on our recent preliminary work at the site. This includes a reassessment of the Taung Child Type Site, as well as renewed excavations at Equus Cave and the lesser-known locality and little-investigated Black Earth Cave. Preliminary results suggest that much of our previous understandings of the BNL’s formational history and site formation processes need to be reassessed. Only through detailed analysis on the BNLas a whole can we understand this complex depositional environment.

description: A passive optical network (PON) based on non-orthogonal multiple access (NOMA) meets low latency and high capacity. In the NOMA-PON, the asynchronous clocks between the strong and weak optical network units (ONUs) cause the timing error and phase noise on the signal of the weak ONU. The theoretical derivation shows that the timing error and phase noise can be independently compensated. In this Letter, we propose a timing recovery (TR) algorithm based on an absolute timing error detector (Abs TED) and a pilot-based carrier phase recovery (CPR) to eliminate the timing error and phase noise separately. An experiment for 25G NOMA-PON is set up to verify the feasibility of the proposed algorithms. The weak ONU can achieve the 20% soft-decision forward error correction limit after compensating for timing error and phase noise. In conclusion, the proposed TR and the pilot-based CPR show great potential for the NOMA-PON.

description: Il saggio indaga, a partire da un sondaggio nelle schede lessicografiche sanguinetiane, la presenza di Boccioni nell’attività del poeta genovese. Il lessicomane Sanguineti condivide con l’artista la mania del collezionismo, come si evince dall’Atlas boccioniano, composto con alcune riproduzioni tratte da «Emporium», spesso riutilizzate come apparato iconografico. Gli esiti di questa indagine permettono una valutazione più chiara delle rispettive posture d’avanguardia.
description: The essay, based on a survey into Sanguineti's lexicographic cards, investigates the presence of Boccioni in the activity of the Genoese poet. Sanguineti, who defines himself as “lessicomane”, shared with the artist a passion for collecting, as can be seen in Boccioni's Atlas, composed with reproductions taken from ‘Emporium’, often reused as an iconographic apparatus. The results of this investigation allow a clearer evaluation of the respective avant-garde postures.

Geospecific View Generation -- Geometry-Context Aware High-resolution Ground View Inference from Satellite Views

Subjects: subject: Computer Vision and Pattern Recognition (cs.CV)

description: Predicting realistic ground views from satellite imagery in urban scenes is a challenging task due to the significant view gaps between satellite and ground-view images. We propose a novel pipeline to tackle this challenge, by generating geospecifc views that maximally respect the weak geometry and texture from multi-view satellite images. Different from existing approaches that hallucinate images from cues such as partial semantics or geometry from overhead satellite images, our method directly predicts ground-view images at geolocation by using a comprehensive set of information from the satellite image, resulting in ground-level images with a resolution boost at a factor of ten or more. We leverage a novel building refinement method to reduce geometric distortions in satellite data at ground level, which ensures the creation of accurate conditions for view synthesis using diffusion networks. Moreover, we proposed a novel geospecific prior, which prompts distribution learning of diffusion models to respect image samples that are closer to the geolocation of the predicted images. We demonstrate our pipeline is the first to generate close-to-real and geospecific ground views merely based on satellite images.

description: The chirality in soft triaxial nuclei is investigated for the first time with the time-dependent and tilted axis cranking covariant density functional theories on a three-dimensional space lattice in a microscopic and self-consistent way. Taking the puzzling chiral nucleus $^{106}$Ag as an example, the experimental energies of the observed nearly degenerate bands are well reproduced without any free parameters beyond the well-defined density functional. A novel chiral mode in soft triaxial nuclei is newly revealed from the microscopic dynamics of the total angular momentum. This opens a new research area for the study of chirality, particularly in relation to soft nuclear shapes.

description: Molybdenum disulfide is considered as one of the most promising two-dimensional semiconductors for electronic and optoelectronic device applications. So far, the charge transport in monolayer molybdenum disulfide is dominated by extrinsic factors such as charged impurities, structural defects and traps, leading to much lower mobility than the intrinsic limit. Here, we develop a facile low-temperature thiol chemistry to repair the sulfur vacancies and improve the interface, resulting in significant reduction of the charged impurities and traps. High mobility greater than 80cm2 V-1 s-1 is achieved in backgated monolayer molybdenum disulfide field-effect transistors at room temperature. Furthermore, we develop a theoretical model to quantitatively extract the key microscopic quantities that control the transistor performances, including the density of charged impurities, short-range defects and traps. Our combined experimental and theoretical study provides a clear path towards intrinsic charge transport in two-dimensional dichalcogenides for future high-performance device applications.
