Abstract
Pyrene-based metal-organic frameworks (MOFs) have tremendous potential for various applications. With infinite structural possibilities, the MOF community often relies on simulations to identify the most promising candidates for given applications. Among thousands of reported structures, many exhibit limited reproducibility — in either synthesis, performance, or both — owing to the sensitivity of synthetic conditions. Geometric distortions that may arise in the functional groups of pyrene-based ligands during synthesis and/or activation cannot easily be predicted. This sometimes leads to discrepancies between in silico and experimental results. Here, we investigate a series of pyrene-based MOFs for carbon capture. These structures share the same ligand (1,3,6,8–tetrakis(p–benzoic acid)pyrene (TBAPy)) but have different metals (M-TBAPy, M = Al, Ga, In, and Sc). The ligands stack parallel in their orthorhombic crystal structure, creating a promising binding site for CO2. As predicted, the metal is shown to affect the pyrene stacking distance and, therefore, the CO2 uptake. Here, we investigate the metal’s intrinsic effects on the MOFs’ crystal structure. Crystallographic analysis shows the emergence of additional phases, which thus impacts the overall adsorption characteristics of the MOFs. Considering these additional phases improves the prediction of adsorption isotherms, enhancing our understanding of pyrene-based MOFs for carbon capture.

Abstract
Accurate characterization of space radiation exposure is critical to assess and communicate multiple health risks for crewmembers participating in future exploration missions. A combination of models and on-board instruments are utilized to meet this requirement. In this work, computational models are evaluated against spaceflight measurements taken within the International Space Station, the Orion spacecraft, the BioSentinel CubeSat, and on the Martian surface. All calculations and measurements cover the exact same time period defined by the Artemis-I mission, and all model calculations were performed blind—without prior knowledge of the measurements. The models are shown to accurately characterize the absorbed dose-rate in highly complex and diverse shielding configurations in locations from Earth to Mars.

Abstract
New research has highlighted a shortfall in the Standard Model (SM) because it predicts neutrinos to have zero mass. However, recent experiments on neutrino oscillation have revealed that the majority of neutrino parameters indeed indicate their significant mass. In response, scientists are increasingly incorporating discrete symmetries alongside continuous ones for the observed patterns of neutrino mixing. In this study, we have examined a model within
$$SU(2)_L \times U(1)_Y \times A_{4}\times S_2\times Z_{10} \times Z_{3}$$
symmetry to estimate the neutrino masses using particle swarm optimization technique for both mass hierarchy of neutrino. This model employed a hybrid seesaw mechanism, a combination of seesaw mechanism of type-I and type-II, to establish the effective Majorana neutrino mass matrix.

Published: February 2025

Abstract
In tropical oceans, phytoplankton experience significant alterations during marine heatwaves (MHWs), yet the consequences of reduced or absent marine cold-spells (MCSs) on these microscopic algae are currently overlooked. Synergistically combining in situ measurements, Argo-float data, remotely-sensed observations, and hydrodynamic model outputs, we explore such relationships in the Red Sea. Results show a long-term (1982 to 2018) gradual increase in MHW days (5–20 days/decade) and a clear decrease in MCS days (10–30 days/decade). Compound extreme temperature and chlorophyll-a events (Chl-a – an index of phytoplankton biomass) exhibit consistently lower Chl-a concentrations during MHWs and higher ones during MCSs, particularly in the northern and southern Red Sea. In these regions, during the main phytoplankton-growth period, the presence of MHWs/MCSs leads to respective Chl-a anomalies in 94% of the cases. Yet, phytoplankton responses in the central Red Sea are more complex, most likely linked to the region’s highly dynamic circulation (e.g., mesoscale anti-cyclonic eddies), and multiple nutrient sources. In the naturally warm and stratified ecosystem of the Red Sea, where deeper mixed layers enhance the transfer of nutrient-rich waters to the lit zone, the substantial reduction of MCSs could be more impactful for phytoplankton than the gradual rise of MHWs.

Published: February 2025

Abstract
Spatial development and landscape pattern are fundamental elements of the land system of village. Analysing the spatial differentiation and coupling relationship between spatial development intensity and landscape pattern is of great significance for the development and protection of village land resources. In order to address the current research lack on the coupling response between village spatial development intensity and landscape pattern, a technical method for analysing the spatial differentiation and coupling relationship between village spatial development intensity and landscape pattern is constructed based on the methods of village spatial development intensity model, landscape pattern index, bivariate spatial autocorrelation model, coupling degree and coupling coordination degree model. Taking 100 villages in Anhui Province, China as an example, the spatial distribution characteristics and coupling characteristics of village spatial development intensity and landscape pattern are analysed. The results show that there are obvious regional differences in the spatial distribution of village spatial development intensity and landscape pattern in Anhui Province. The village spatial development intensity shows a pattern of the Northern Anhui plain region (NAPR) > along the Yangtze River plain region (YRPR) > Jiang-huai Hilly region (JHHR) > Southern Anhui mountainous region (SAMR) > Western Anhui mountainous region (WAMR). The village landscape pattern in NAPR and YRPR are high fragmentation, while the village in JHHR has the lowest fragmentation, and the villages in SAMR and WAMR show relatively low fragmentation. The spatial coupling relationship between village spatial development intensity and landscape pattern is mainly characterised by high-high clustering and low-high clustering. The coupling coordinated development of villages in NAPR is the best, followed by YRPR, JHHR and SAMR, and WAMR is the worst. There is only a significant multi-linear relationship between village landscape pattern and multiple spatial development intensity indicators in WAMR and NAPR. The spatial differentiation and coupling relationship are influenced by both natural geographical factors and human activity factors. Finally, the study puts forward some targeted countermeasures and suggestions. The research results can provide theoretical method and practical application reference for village land space development and protection and village planning.
Catalytic degradation of norfloxacin using persulfate activation by Ni-Fe layered double hydroxide catalyst supported on activated carbon
Authors: Adly Adel , Galal Mona M , Matta Minerva E 
Published: February 2025

Abstract
This study investigated the catalytic degradation of Norfloxacin (NOR), a persistent fluoroquinolone antibiotic, using a novel Ni-Fe Layered Double Hydroxide supported on Activated Carbon (NiFe-LDH@AC) as a catalyst. The composite was designed to activate persulfate (PDS) and generate sulfate radicals for NOR degradation in aqueous solutions. Characterization techniques such as XRD, SEM, EDS, TEM, FTIR, and BET confirmed the successful synthesis and structural integrity of the composite. The optimal degradation was achieved with a NiFe-LDH@AC ratio of 2:1, 0.3 g/L catalyst dosage, and 1 g/L PDS, resulting in 86% NOR removal efficiency within 60 min at neutral pH and ambient temperature for an initial concentration of 50 mg/L, and 100% removal for initial concentrations of 10 mg/L and 20 mg/L under the same conditions. The activation energy of the reaction was calculated as 58.27 kJ/mol. Radical scavenging experiments identified sulfate (SO₄˙⁻) and hydroxyl (•OH) radicals as the dominant reactive species, but the SO₄˙⁻ played a larger role. Furthermore, the catalyst exhibited good reusability, maintaining 75% degradation efficiency after four cycles, and showed minimal metal leaching. The study also proposed a mechanism for PDS activation using XPS analysis and suggested NOR degradation pathways through LC-ESI-MS/MS analysis. Moreover, the NiFe-LDH@AC/PDS system demonstrated 84% NOR degradation and 55% COD removal in real treated wastewater. Results demonstrated that the NiFe-LDH@AC composite effectively activated PDS, achieving high NOR removal efficiency, making it a promising sustainable material for wastewater treatment.

Published: February 2025

Abstract
Health systems must solve two climate-related problems simultaneously: mitigate their greenhouse gas emissions and adapt to additional patient loads associated with climate-induced demands for care from weather sequalae and vector-borne diseases. We aimed to benchmark the mitigation and adaptive efforts of OECD member countries compared with their health system performance. We used Multidimensional Scaling and Hierarchical Cluster Analysis to group all 38 OECD member countries as at January 2024. Clusters were defined according to greenhouse gases per capita, vulnerability to climate change and the United Nations’ Human Development Index. Post hoc analyses compared each cluster’s performance to the OECD’s Health Care Quality Indicators. The countries fell into five profiles: Vulnerable low emitters; Vulnerable aspiring; Middle of the road; Robust aspiring; and Goldilocks zone. Post-hoc analyses revealed strong links between the profiles and health system performance. Characterising countries in a five-dimensional model may help policymakers to share benchmarked country-level information, devise ways to support resilient care practices, better target healthcare investments, and improve access to needed care.
Extreme two-phase change of ionospheric electron temperature overshoot during geomagnetic storms

Published: February 2025

Abstract
An intense surge in the equatorial electron temperature (Te) at sunrise, known as the morning Te overshoot, has been one of the defining ionospheric features since its discovery early in the Space Age. Despite decades of study, the behavior of the morning overshoot during geomagnetic storms remains poorly understood. We report a two-stage response of the morning Te overshoot to geomagnetic activity, uncovered by a neural network model. Electron temperatures show an initial enhancement during the storm’s main phase, followed by a drastic depletion exceeding 1000 K and disappearance of the overshoot in the recovery phase. This two-phase change aligns with the early influence of westward prompt penetration electric field, overtaken by the development of the eastward disturbance dynamo later in the storm. These electric field changes affect vertical plasma drifts that redistribute electron densities, modifying ionospheric cooling rates. Our findings provide new insights into the dynamics of one of the most widely studied ionospheric features and showcase the potential of new-generation digital twin models of near-Earth space environment to reveal previously unrecognized physical patterns.

Abstract
Continuous access to electronic health records will fuel the digital transformation of medicine. For data-sharing initiatives, the challenge lies in ensuring data access aligns with the interests of data holders. Federated data access authorization, where data remains controlled locally, may offer a solution to balance these interests. This paper reports on a digital health implementation of the federated data access authorization system used in the German National Emergency Department Data Registry. Using data from 2017 to 2024, we analyzed the system’s effectiveness in managing data access in a nationwide research network of 58 emergency departments. Facilitating access to more than 7.9 million records, 75% of data access queries were authorized within 15 days. The system also supports periodic queries, enabling recurring real-time access. Query volumes grew from 15 to over 23,000 by 2024, with completion rates of 86%. The system may thus serve as a blueprint for data-sharing initiatives worldwide.

The Role of Parental Temperament and Parent–Child Fit in Two Stuttering Therapy Programs for Preschool-Aged Children Who Stutter: A Preliminary Study
Authors: Berani Diellza , Franken Marie-Christine , Stipdonk Lottie 
Published: February 2025

Purpose:
To understand factors contributing to therapy success, this study investigated the role of parents' temperament and the fit between parents' temperament and parent-reported child behavior problems in therapy outcomes across two therapy types.

Method:
A total of 177 children who stutter and their parents were included in this study. Data from 149 children were present at the follow-up. Children received either Lidcombe Program (LP) or Rotterdam Evaluation Study of Stuttering Therapy randomized trial–Demands and Capacities Model (RESTART-DCM) therapy. Parents' temperaments and children's behaviors were measured at baseline. At 18 months of therapy postonset (T4) and 5 years later (T5), the children's remittance or persistence in stuttering was assessed.

Results:
High parental novelty seeking and high harm avoidance were associated with transient stuttering at T4 in the entire sample. Looking across therapies, novelty seeking remained significant in the RESTART-DCM group at T4, whereas in the LP group, significant associations were observed for reward dependence (at T4 and T5) and persistence (at T4). Meanwhile, none of the parent–child fits were associated with therapy outcome.

Conclusions:
The results suggest that for preschoolers receiving treatment, parents who tend to seek novelty and exploration, as well as those with greater vigilance toward harm, have a positive impact on therapy success. In contrast, socially dependent parents might have a negative impact on therapy success in children receiving LP treatment, whereas diligent parents could serve as a protective factor in this therapy. These exploratory results should be interpreted with caution, and future research will be crucial to confirm and further interpret these results.
Toward a Taxonomy for Supraglottic Structure Vibrations in Voice: A Narrative Literature Review
Authors: Aaen Mathias , Sadolin Cathrine , McGlashan Julian 
Published: February 2025

Objective:
Supraglottic structures can be used as a sound source in both pathological and healthy voice production. In professional voice users, supraglottic vibration phenotypes have been previously identified; however, at present, no reviews integrating literature on the topic are available. This narrative literature review provides an integrative narrative to develop a taxonomy of supraglottic sound sources, including distinguishing vibrational strategy, level of control, number of vibrating sources, and phenotypes.

Method:
This study used a narrative literature review integrating extant literature on supraglottic sound source use in professional voice users into a taxonomy.

Results:
Supraglottic sound source use can be described according to four dimensions: (a) vibrational strategy including supplementary or substitutional functions, (b) level of control including intentional and unintentional supraglottic vibrations, (c) number of supraglottic sources including unisource and multisource types, and (d) supraglottic phenotypes related to ventricular-on-ventricular, arytenoid-on-arytenoid, cuneiform/arytenoid apex-on-epiglottis, and aryepiglottic fold and laryngeal mucosa low amplitude vibrations. The physiology, acoustic impact, electroglottographic oscillation, and sound exemplars are discussed for each phenotype. The narrative review highlights several gaps in current knowledge about both specific supraglottic vibration patterns and overlaps between pathological and healthy supraglottic sound source use.

Conclusions:
Supraglottic sound sources and their use can be described in an integrative taxonomy for professional voice users along four dimensions that each describes distinct facets. The taxonomy has conceptual, health, pedagogical, perceptual, and potentially clinical relevance, each of which is discussed in turn.
A structure‐prior guided adaptive context selection network for remote sensing semantic segmentation
Authors: Xu Shengjun , Shen Rui , Liu Erhu , Ma Zongfang , Du Miao , Liu Jun , Zhan Bohan 
Published: February 2025

AbstractIn remote sensing image segmentation, recognizing buildings is challenging when the visual evidence from pixels is weak or when buildings belong to small, spatially structured objects. To address this issue, a structure‐prior guided adaptive context selection network (SGACS‐Net) is proposed for remote sensing semantic segmentation. The core is to use structure‐prior knowledge to dynamically capture prior contextual information and higher‐order object structural features, thereby improving the accuracy of remote sensing building segmentation. First, an adaptive context selection module is designed. By dynamically adjusting the spatial sensing field, this module effectively models the global long‐range context information dependencies. It captures varying context information of buildings at different scales, thereby enhancing the network's ability to extract building feature representations. Second, a structure‐prior guided variable loss function is proposed. It utilizes the structural features of building points, lines, and surface to identify key regions. By leveraging advanced structure‐prior knowledge, it enhances the network's ability to express structural features. Experimental results on two datasets show that the proposed SGACS‐Net outperforms other typical and state‐of‐the‐art methods in terms of remote sensing semantic segmentation performance.

AbstractThis study aims to exploit the resistance states of Cr/ZnO/TiN memristors to generate random numbers. A random number generator (RNG) circuit employing a single memristor is proposed. We suggest that current compliance (CC) is a significant parameter in determining the quality of randomness; it is found that low CCs (20‐50 µA) have a wide resistance state distribution that facilitates random bits. This work provides insight into the implementation of memristors for data security applications.

ABSTRACTThis paper discusses the power electronic converter's architecture and control for overtopping breakwater for wave energy conversion (OBREC) systems for the first time for this kind of technology. After a recall of the main OBREC's components, their dynamic models and control strategies are briefly summarized. Then, an innovative maximum power point tracking strategy is proposed, and a proactive overview of different existing power electronic architectures to connect the OBREC system to the harbour's electrical distribution systems is conducted. The whole converter's control design process is preliminarily tested utilizing the processor‐in‐the‐loop tool implemented in the Matlab environment. Finally, two numerical case studies on a realistic scenario are discussed and commented.
