Authors: KhairEldin Mohamed , Daoud Ahmed Osama , Ibrahim Ahmed Hussein , Toma Hossam M. 
Published: January 2025

Abstract
Effective construction waste (CW) management, mainly concrete, brick, and steel, is a critical challenge due to its significant environmental and economic impacts. This study addresses this challenge by proposing multiple linear regression models to predict waste generation in residential buildings within the Egyptian construction industry, considering the influence of factors such as building design and site management features. Using data from 25 case studies, the models demonstrated high predictive accuracy, with adjusted R² values of 0.877, 0.893, and 0.889 for concrete, bricks, and steel waste, respectively. These R2 values indicate that the models explain approximately 88–89% of the variance in waste generation in residential buildings, highlighting their effectiveness in enhancing resource planning and waste management strategies. The findings suggest that incorporating variables such as total area, design consistency, and site organization significantly improves the accuracy of waste predictions. Although the models show acceptable performance, future research should aim to expand the dataset, incorporate additional variables, and test the models across different types of construction projects to validate further and refine these predictive tools. The models offer valuable insights for enhancing construction practices, minimizing waste, and supporting sustainable development in Egypt’s construction industry. With accurate forecasts of waste generation, the models help project managers and stakeholders to plan CW more effectively, mitigating unnecessary material consumption and reducing environmental impacts. These findings help to adopt sustainable construction practices, such as improved recycling processes and decreased dependence on landfills, to support Egypt’s Vision 2030.

Abstract
Elevated cortisol in chronic stress and mood disorders causes morbidity including metabolic and cardiovascular diseases. There is therefore interest in developing drugs that lower cortisol by targeting its endocrine pathway, the hypothalamic–pituitary–adrenal (HPA) axis. However, several promising HPA-modulating drugs have failed to reduce long-term cortisol in mood disorders, despite effectiveness in other hypercortisolism conditions such as Cushing’s syndrome. The reasons for these failures remain unclear. Here, we use a mathematical model of the HPA axis to demonstrate that the pituitary and adrenal glands compensate for drug effects by adjusting their functional mass, a feedback mechanism absent in Cushing tumors. Our systematic in silico analysis identifies two interventions targeting corticotropin-releasing hormone (CRH) as effective for lowering long-term cortisol. Other targets either fail due to gland mass compensation or harm other aspects of the HPA axis. We propose CRH-neutralizing antibodies and CRH-synthesis inhibitors as potential targets for reducing long-term cortisol in mood disorders and chronic stress. More generally, this study indicates that understanding the slow compensatory mechanisms in endocrine axes can be crucial to prioritize drug targets.

Published: January 2025

AbstractAccurate and efficient calculation of a transformer's magnetic field is fundamental for the rapid calculation of its losses, temperature rise, and structural forces. However, existing numerical methods for calculating the harmonic magnetic field of a product‐level transformer are time‐consuming and fail to meet the rapid requirements of digital operations and maintenance. To address this, this paper first utilises the harmonic field method to obtain the snapshot matrix of the transformer's magnetic field. Subsequently, a response surface model of the magnetic field is constructed using intrinsic quadrature theory and radial basis functions in the augmented form. To enhance the efficiency of constructing the reduced‐order model, an adaptive Latin hypercube sampling method, integrating the additive rule and leave‐one‐out cross‐validation, is introduced, significantly improving the efficiency of sample space construction. The effectiveness of the proposed method is validated by applying the proper orthogonal decomposition‐radial basis function including linear polynomial (POD‐RBFLP) method to calculate the harmonic magnetic field of a three‐phase power transformer in reduced order. The results are compared with those from COMSOL calculations, showing that the reduced‐order model maintains the calculation error within a reasonable range, thereby confirming the accuracy of the proposed method. Additionally, the reduced‐order model demonstrates a significant advantage in computation time compared to COMSOL simulations, enabling the calculation of the transformer's magnetic field in seconds.
A stellar census in globular clusters with MUSE

Published: January 2025

Context. Multiple populations are ubiquitous in the old massive globular clusters (GCs) of the Milky Way. It is still unclear how they arose during the formation of a GC. The topic of iron and metallicity variations has recently attracted attention with the measurement of iron variations among the primordial population (P1) stars of Galactic GCs.
Aims. We explore the relationship between the metallicity of the P1 stars on the red-giant branch (RGB) of Galactic GCs and their ∆F275W,F814W pseudo-color. We also measure the metallicity dispersion of P1 and P2 stars.
Methods. We used the spectra of more than 8000 RGB stars in 21 Galactic GCs observed with the integral-field spectrograph MUSE to derive individual stellar metallicities, [M/H]. For each cluster, we used Hubble Space Telescope photometric catalogs to separate the stars into two main populations (P1 and P2). We measured the metallicity spread within the primordial population of each cluster by combining our metallicity measurements with the stars’ ∆F275W,F814W pseudo-color. We also derived metallicity dispersions (σ[M/H]) for the P1 and P2 stars of each GC.
Results. In all but three GCs we find a significant correlation between the metallicity and the ∆F275W,F814W pseudo-color of the P1 stars: stars with larger ∆F275W,F814W have higher metallicities. We measure metallicity spreads that range from 0.03 to 0.24 dex and correlate with the GC masses. As for the intrinsic metallicity dispersions, when combining the P1 and P2 stars, we measure values ranging from 0.02 dex to 0.08 dex, which correlate very well with the GC masses. The two clusters that show the largest σ[M/H] are NGC 6388 and NGC 6441. The P2 stars have metallicity dispersions that are smaller than or equal to those of the P1 stars.
Conclusions. We present a homogeneous spectroscopic characterization of the metallicities of the P1 and P2 stars in a set of 21 Galactic GCs. We find that both the metallicity spreads of the P1 stars (from the ∆F275W,F814W spread on the chromosome maps) and the metallicity dispersions (σ[M/H]) correlate with the GC masses, as predicted by some theoretical self-enrichment models presented in the literature.

Context. The hypergiant RW Cep is one of the largest stars in the Galaxy. The evolution and mass loss of such stars have profound effects on their surrounding regions and their galaxy as a whole. Between 2020 and 2024, RW Cep experienced a historic mass-loss event known as the Great Dimming.
Aims. This study provides a spectroscopic analysis of RW Cep during the Great Dimming. We examine its atmospheric dynamics and place it in the context of the star’s variability behaviour since the early 2000s.
Methods. We conducted high-cadence spectroscopic observations of RW Cep during the dimming event using the Tartu Observatory 1.5-meter telescope and the Nordic Optical Telescope. We analysed the atmospheric dynamics by measuring the radial velocities and line depths of Fe I and other spectral lines.
Results. The radial velocities of the Fe I lines reveal a vertical velocity gradient of 10–20 km s−1 in the atmosphere, correlating with the strength of the spectral lines. Stronger lines, formed in higher atmospheric layers, have higher radial velocities. We measured the systemic velocity at −50.3 km s−1. During the dimming, radial velocities were affected by additional emission from the ejected gas, which was blue-shifted relative to the absorption lines. Post-dimming, we observed large-scale atmospheric motions with an amplitude of ~25 km s−1. Strong resonance lines of Ba II, K I, Na I, and Ca I showed stable central emission components at −56 km s−1, which are likely of circumstellar origin.

AbstractEight new 4,5-seco-abietane-type diterpenes, salpratones B–I, along with two analogues, featuring diverse 6/5/6, 6/6/6, 6/6/7, and 6/6/8 ring systems, were isolated from Salvia prattii. Notably, salpratone B is the first example of a 4,5;13,14-bis-seco-abietane diterpene characteristic with a rare rearranged 6/5/6 tricyclic core skeleton. Their structures were determined by comprehensive NMR spectroscopy, single-crystal X-ray diffraction, and electronic circular dichroism. Moreover, salpratones B–D were resolved into optically pure enantiomers. Partial diterpenes were evaluated for their in vitro anticoagulant activities. While salpratones B, E, F can weakly prolong the clotting times of human plasma in the activated partial thromboplastin time (APTT) assays with concentrations of 100 μM, showing no appreciable anticoagulant activities.
Temperature-dependent optical constants of nanometer-thin flakes of Fe(Te,Se) superconductor in the visible and near-infrared regime
Authors: Pattanayak Aswini K. , Rout Jagi , Jha Pankaj K. 
Published: January 2025

Iron chalcogenide superconductors, such as Fe(Te,Se), have recently garnered significant attention due to their simple crystal structure with a relatively easy synthesis process, high-temperature superconductivity, intrinsic topological band structure, and an unconventional pairing of superconductivity with ferromagnetism. Here, we report the complex in-plane refractive index measurement of a nanometer-thin Fe(Te,Se) flake exfoliated from a single crystal FeTe0.6Se0.4 for photon wavelengths from 450 to 1100 nm over a temperature range from 4 to 295 K. The results were obtained by employing a two-Drude model for the dielectric function of Fe(Te,Se), a multiband superconductor, and fitting the absolute optical reflection spectra using the transfer matrix method. A high extinction coefficient in the visible to near-infrared range makes nanometer-thin Fe(Te,Se) flakes a promising material for photodetection applications.
Voices in the Linguistic Landscape
Authors: Heyd Theresa , Pithan Jana 
Published: January 2025

Abstract
This paper contributes to the emerging analytical framework of anthropo­morphized artifacts as part of Linguistic
Landscapes. It describes and analyzes cases where signage, objects, or related inanimate objects are inscribed with language that
includes first-person pronoun usage and thus constructs the notion of speakerhood. We analyze a corpus of over 80 such items and
provide qualitative analysis that includes structural aspects such as emerging syntactic regularities as well as the prevalence of
graphematic and stylistic informality markers. We identify discursive and pragmatic functions that the construction of voice has
in the analyzed material. We connect the phenomenon and our findings to theories of anthropo­morphization in general and to
current developments in posthumanist linguistics and the uncertain epistemic status of speakerhood more specifically.
Approaching language rights and justice for linguistic minorities from the perspective of constitutional
economics
Authors: Wickström Bengt-Arne 
Published: January 2025

Abstract
Methodological individualism is a central concept in normative economics. As the point of departure of our
discussion of linguistic justice, we postulates the equality of all individuals in relation to their first language. Any deviation
from this ideal has to be motivated. One such motivation is the impracticability of policy measures, for instance due to cost
arguments. A constitutional-economics analysis of the allocation of language rights focuses on this trade-off between equity and
efficiency. One can define a scale running from perfect equality combined with extensive inefficiency to perfect efficiency
combined with considerable inequalities between different individuals of different mother tongues. “(Linguistic) justice” of
public policy is then defined as an “optimal” choice, or trade-off, on this scale.
For the analysis, two tools in the tool chest of the economist will be applied in this essay:

An intuitive-imaginary analysis, based on a Gedankenexperiment involving an
imaginary “original position” behind a “veil of ignorance” from which the choice between different societies can be seen
as an individual’s choice of implicit income distributions under uncertainty about the individual’s own position in this
distribution. The chosen society is then defined as “just” and the choice is determined by the individuals’ attitude
towards uncertainty.

A formal-axiomatic definition of a (paretian) social-welfare function in implicit incomes (money
income plus perceived value of, for instance, language rights) of all citizens in the society. The definition of “justice”
is then found in the formal properties of this welfare function.

Both approaches lead to the same qualitative results.
Spatial curvature in coincident gauge f(Q) cosmology
Authors: Jensko Erik 
Published: January 2025

Abstract
In this work we study the Friedmann–Lemaître–Robertson–Walker cosmologies with arbitrary spatial curvature for the symmetric teleparallel theories of gravity, giving the first presentation of their coincident gauge form. Our approach explicitly starts with the cosmological Killing vectors and constructs the coincident gauge coordinates adapted to these Killing vectors. We then obtain three distinct spatially flat branches and a single spatially curved branch. Contrary to some previous claims, we show that all branches can be studied in this gauge-fixed formalism, which offers certain conceptual advantages. We also identify common flaws that have appeared in the literature regarding the coincident gauge. Using this approach, we find that both the flat and spatially curved solutions in f(Q) gravity can be seen as equivalent to the metric teleparallel f(T) models, demonstrating a deeper connection between these theories. This is accomplished by studying the connection equation of motion, which can be interpreted as a consistency condition in the gauge-fixed approach. Finally, we discuss the role of diffeomorphism invariance and local Lorentz invariance in these geometric modifications of gravity.
Mean-field criteria for the onset of discontinuous recrystallization in cold rolled aluminum alloys
Authors: Falkinger Georg , Kahlenberg Robert , Theissing Moritz , Tosone Ramona , Pogatscher Stefan 
Published: January 2025

Abstract
Discontinuous subgrain growth is an important mechanism for the formation of recrystallization nuclei during annealing after cold rolling of aluminum alloys. Based on the analytical textbook theory for continuous and discontinuous growth of cellular microstructures, we derive and validate simple mean-field criteria for the onset of discontinuous recrystallization in aluminum alloys. The determining factors in the criteria are the stored energy after deformation, the rate of recovery and the mobility of large angle grain boundaries. The criteria are successfully applied to isothermal annealings and annealings at constant heating rates. They can be combined with arbitrary mean-field recovery models, including the widely used phenomenological softening laws.

Abstract
To implement a neuromorphic computing system capable of efficiently processing vast amounts of unstructured data, a significant number of synapse and neuron devices are needed, resulting in increased area demands. Therefore, we developed a nanoscale vertically structured synapse device that supports high-density integration. To realize this synapse device, the interface effects between the resistive switching layer and the electrode were investigated and utilized. Electrical and physical analyses were conducted to comprehend the operational mechanism of the developed synapse device. The results indicate that oxygen ions from the resistive switching layer were absorbed by the electrode, forming metal–oxygen bonds. The

Abstract
We investigate the effect of focused-ion-beam (FIB) irradiation on spin waves with sub-micron wavelengths in yttrium-iron-garnet films. Time-resolved scanning transmission x-ray microscopy was used to image the spin waves in irradiated regions and deduce corresponding changes in the magnetic parameters of the film. We find that the changes of Ga+ irradiation can be understood by assuming a few percent change in the effective magnetization

A mutually injected multi-wavelength opto-optic microwave oscillator
Authors: Zhu Xiang , Huang Yali , He Tong , Yu Xianbin 
Published: January 2025

Abstract
Flexible opto-optic microwave oscillators (OOMO) have high potential for providing both optical and electrical signals with high quality. In this work, a scalable OOMO with iterative substructures is proposed and demonstrated. Different from the previous all-optical microwave oscillators, multiple lasers with different wavelengths in an opto-optic oscillation loop serve as a series of optical carriers to support the Vernier effect in the wavelength domain. By performing mutual injection between various laser carriers in a single loop with the semiconductor optical amplifiers (SOAs) as the modulators, the gain competition between the laser carriers in the SOAs can be prevented, and stable and single-mode oscillation without an ultranarrow bandpass filter can be realized. We experimentally demonstrate a single-loop OOMO based on the proposed method, and tunable dual-wavelength optical signals for generating microwave signals with low phase noises in a wideband are successfully achieved. The scalable structure of this oscillator is expected to be applicable in the high-quality wavelength division multiplexing applications.

Published: January 2025

Abstract
The aim of this work is the development of scientifically based ways of influencing the process of nucleation of crystallization centres to control the cast structure and the properties of blanks at the casting stage. The possibility of controlling crystal nucleation was studied on transparent modelling media using the droplet method. The dependence of the crystallization kinetics of drops with a size of 100÷200 μm on the overheat temperature (up to 15 degrees), the exposure in the overheated state and the degree of supercooling (up to 10 degrees) were established. The curves of the crystallization kinetics of drops from their melts were chosen as the criteria for evaluating the crystallization process. The nature of the change in the experimental media crystallization kinetics curves confirms the assumption about the decisive role of impurities in the crystallization processes of any alloys. The confirmation of the hypothesis about the decisive role of impurities in the processes of crystallization from positions of heterogeneous nucleation is the dependence of the number of solidified drops with the same diameter on the degree and duration of their overheating.
