Classical Arabic poetry played a powerful social role in Arab society, particularly during the Jāhiliyya (pre-Islamic) period, due to its high level of eloquence (faṣāḥa) and balāgha. Within this poetic tradition—shaped around themes such as heroism (ḥamāsah), boasting (fakhr), satire (hijā’), and love (tashbīb)—‘aṣabiyya occupied a central position as a means of constructing and preserving tribal identity through language. Poets exalted their own tribes and disparaged rival ones by employing persuasive and emotionally charged expression. With the revelation of the Qur’an in 610 CE, this literary and cultural heritage, grounded in aesthetic and expressive power, was reconfigured within a new religious framework. The Qur’an’s challenge-oriented discourse entered into direct interaction with existing poetic sensibilities. Against this background, the present study examines the transformation of ‘aṣabiyya in classical Arabic poetry during the early Islamic period. It offers a comparative analysis of lineage-centered ‘aṣabiyya in Jāhiliyya poetry and the emergence of an ummah-centered discourse of unity in Islamic poetry, drawing on poems by different poets from both periods. Using content analysis, rhetorical text analysis, and inductive methods, the study demonstrates that the Qur’an’s influence on Arabic poetry was neither uniform nor one-dimensional but significantly shaped poetic themes and authorial attitudes. By focusing on ‘aṣabiyya, the article aims to contribute to a renewed understanding of the Qur’an–poetry relationship in early Islam. Full article

This article examines Daniel 10 as a key witness to the formation of early Jewish apocalyptic literature. The chapter portrays Daniel as a sage whose encounter with a celestial messenger prepares him to guide his community. Narratively, this scene introduces the final revelation of Daniel 11–12; ideologically, it expresses the authors’ conviction that access to the heavenly realm is achieved through scribal discipline and engagement with inherited traditions. The study advances two related contributions. Drawing on recent reassessments of apocalyptic origins—especially insights from Aramaic texts at Qumran—the study offers a new analysis of intertextuality in Daniel 10, highlighting how apocalyptic writing predates the persecutions of Antiochus IV and is developed through the reinterpretation of authoritative Scriptures in the Persian and Hellenistic periods. Daniel’s profile aligns with elite temple-based scribes who operated across imperial and cultic settings and used apocalyptic discourse in intra-Judean power struggles. In addition, the reference to the Tigris in Dan 10:4 is reinterpreted in light of Seleucia-on-Tigris, whose culturally hybrid environment illuminates the cosmopolitan backdrop of the maśkîlîm traditions.

Autoinflammatory diseases involve recurrent systemic inflammation caused by dysregulated innate immunity, arising from genetic or multifactorial mechanisms, as seen in periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome. About 10% of PFAPA patients show autosomal dominant inheritance. We describe a three-generation family with a PFAPA-like recurrent fever syndrome displaying clear autosomal dominant transmission. All affected individuals tested negative on a diagnostic panel of 13 known autoinflammatory genes. Whole-exome sequencing was performed in two distantly related affected members, followed by variant filtering, segregation analysis, and phenotype-based prioritization. A single heterozygous missense variant in RXFP1, c.154G>A p.(Asp52Asn), co-segregated with disease in all affected relatives. This variant is extremely rare in population databases, absent from ClinVar, present in COSMIC, and predicted as damaging by REVEL and CADD. RXFP1, not previously implicated in autoinflammatory or innate immune disorders, encodes the relaxin family peptide receptor 1, a G protein–coupled receptor involved in extracellular matrix regulation, anti-fibrotic pathways, and modulation of inflammatory cytokine production. Protein network analysis showed interactions with RLXN1-3, inflammatory mediators, PTGDR, ADORA2B, and C1QTNF8, supporting an immunomodulatory function. This is the first report linking RXFP1 variation to a hereditary recurrent fever syndrome, identifying relaxin signalling as a potential immune regulatory pathway. Full article

We construct a novel hand-collected large dataset of 205 U.S. hedge funds and 1025 activist events over the period 2005–2013, which records both the Schedule 13D filing date and the voice date, and explore the role of voice in value creation. We employ alternative inferential statistical approaches, including parametric, non-parametric, and heteroscedasticity-robust tests. We reveal that the voice date is important in creating short-term firm value and provide strong evidence that voice is associated with positive abnormal returns. These findings suggest that voice leads to information revelation, with implications for U.S. stock market arbitrage. Full article

Male-factor infertility accounts for approxiamately half of all infertility cases globally, yet therapeutic options remain limited for individuals with no retrievable spermatozoa, such as those with non-obstructive azoospermia (NOA). In recent years, artificial gametogenesis has emerged as a promising avenue for fertility restoration, driven by advances in two complementary strategies: organotypic in vitro spermatogenesis (IVS), which aims to complete spermatogenesis ex vivo using native testicular tissue, and in vitro gametogenesis (IVG), which seeks to generate male gametes de novo from pluripotent or reprogrammed somatic stem cells. To evaluate the current landscape and future potential of these approaches, a narrative, semi-systematic literature search was conducted in PubMed and Scopus for the period January 2010 to February 2025. Additionally, landmark studies published prior to 2010 that contributed foundational knowledge in spermatogenesis and testicular tissue modeling were reviewed to provide historical context. This narrative review synthesizes multidisciplinary evidence from cell biology, tissue engineering, and translational medicine to benchmark IVS and IVG technologies against species-specific developmental milestones, ranging from rodent models to non-human primates and emerging human systems. Key challenges—such as the reconstitution of the blood–testis barrier, stage-specific endocrine signaling, and epigenetic reprogramming—are discussed alongside critical performance metrics of various platforms, including air–liquid interface slice cultures, three-dimensional organoids, microfluidic “testis-on-chip” devices, and stem cell-derived gametogenic protocols. Particular attention is given to clinical applicability in contexts such as NOA, oncofertility preservation in prepubertal patients, genetic syndromes, and reprocutive scenarios involving same-sex or unpartnered individuals. Safety, regulatory, and ethical considerations are critically appraised, and a translational framework is outlined that emphasizes biomimetic scaffold design, multi-omics-guided media optimization, and rigorous genomic and epigenomic quality control. While the generation of functionally mature sperm in vitro remains unachieved, converging progress in animal models and early human systems suggests that clinically revelant IVS and IVG applications are approaching feasibility, offering a paradigm shift in reproductive medicine.

Material stocks (MS) serve as essential physical foundations for socio–economic systems, reflecting the accumulation, transformation, and consumption of resources over time and space. Positioned at the intersection of environmental and socio–economic systems, MS are increasingly recognized as leverage points for advancing sustainability. However, there is currently a lack of comprehensive overview, making it difficult to fully capture the latest developments and cutting–edge research. We adopt a systems perspective to conduct a comprehensive bibliometric and thematic review of 602 scholarly publications on MS research. The results showed that MS research encompasses has three development periods: preliminary exploration (before 2007), rapid development (2007–2016), and expansion and deepening (after 2016). MS research continues to deepen, gathering multiple teams and differentiating into diverse topics. MS research has evolved from simple accounting to intersection with socio–economic, resources, and environmental systems, and shifted from relying on statistical data to integrating high–spatio–temporal–resolution geographic big data. MS research is shifting from problem revelation to problem solving, constantly achieving new developments and improvements. In the future, it is still necessary to refine MS spatio–temporal distribution, reveal MS’s evolution mechanism, establish standardized databases, strengthen interaction with other systems, enhance problem–solving abilities, and provide powerful guidance for the formulation of dematerialization and decarbonization policies to achieve sustainable development.

The aim of sequential recommendation (SR) is to predict a user’s next interaction by analyzing their historical behavioral sequences. The proposed framework leverages the inherent symmetry in user behavior patterns, where temporal and spectral representations exhibit complementary structures that can be harmonized for robust recommendation. Conventional SR methods predominantly utilize implicit feedback (e.g., clicks and views) as model inputs, whereby observed interactions are treated as positive instances, while unobserved ones are considered negative samples. However, the inherent randomness and diversity in user behaviors inevitably introduce noise into such implicit feedback, potentially compromising the accuracy of recommendations. Recent studies have explored noise mitigation through two primary approaches: temporal-domain methods that reweight interactions to distill clean samples for comprehensive user preference modeling, and frequency-domain techniques that purify item embeddings to reduce the propagation of noise. While temporal approaches excel in sample refinement, frequency-based methods demonstrate superior capability in learning noise-resistant representations through spectral analysis. Motivated by the desire to synergize these complementary advantages, we propose SR-DFN, a novel framework that systematically addresses noise interference through coordinated time–frequency processing. Self-guided sample purification is implemented in the temporal domain of our architecture via adaptive interaction weighting, effectively distilling behaviorally significant patterns. The refined sequence is then transformed into the frequency domain, where learnable spectral filters operate to further attenuate residual noise components while preserving essential preference signals. Drawing on the convolution theorem’s revelation regarding frequency-domain operations capturing behavioral periodicity, we critically examine conventional position encoding schemes and propose an efficient parameterization strategy that eliminates redundant positional embeddings without compromising temporal awareness. Comprehensive experiments conducted on four real-world benchmark datasets demonstrate SR-DFN’s superior performance over state-of-the-art baselines, with ablation studies validating the effectiveness of our dual-domain denoising mechanism. Our findings suggest that coordinated time–frequency processing offers a principled solution for noise-resilient sequential recommendation while challenging conventional assumptions about positional encoding requirements in spectral-based approaches. The symmetry principles underlying our dual-domain approach demonstrate how the balanced processing of temporal and frequency domains can achieve superior noise resilience. Full article

Interpretations of the Book of Revelation were extremely popular in the 16th century, not least due to the precarious situation of Protestantism in Europe. In these contexts, the Revelation of John was of utmost importance to the issue of pastoral care in the early modern period, despite the intensive discussions about its canonicity. It contained the most detailed explanations of what awaited Christians after their death and how the events of the end times would unfold until the return of Christ. The perspective of what to expect after death was of great pastoral, and therefore, theological importance. One of the most important commentaries was the ‘Hundred Sermons on the Apocalypse’ by the Zurich-born reformer Heinrich Bullinger. This article examines the biblical concepts of the future that Bullinger identified, as well as the reformer’s own emphases and their practical implications. This article combines, therefore, the flourishing history of the reception of the Bible with the history of Christian conceptions of the future—and its pastoral implications—that have yet to be applied to the Swiss Reformation.

In-depth analysis of the evolution of ecosystem services (ESs) in the basin at different spatial scales, scientific identification of ecosystem service clusters, and revelation of their spatial and temporal characteristics as well as coupling mechanisms of interactions are the key prerequisites for effective implementation of ES management. This paper assessed the spatial and temporal changes of six key ESs covering food provisioning (FP), water yield (WY), soil retention (SR), water conservation (WC), habitat quality (HQ), and carbon sequestration (CS) in the Xijiang River Basin (XRB), China, between 2000 and 2020. Given that the scale effects of ESs and their spatial heterogeneity in the XRB are still subject to large uncertainties, a combination of Spearman correlation analysis and geographically weighted regression (GWR) modelling systematically revealed the trade-offs and synergistic relationships between ESs and the scale effects from a grid, watershed, and county perspective. Additionally, we applied the self-organizing mapping (SOM) method to identify multiple ecosystem service bundles (ESBs) and propose corresponding sustainable spatial planning and management strategies for each cluster. The results reveal the following key findings: (1) Spatial distribution and heterogeneity: The six ESs demonstrated pronounced spatial variability across the study area during the two-decade period from 2000 to 2020. The downstream areas had higher levels of ESs, while the upstream regions showed comparatively lower levels. This trend was particularly evident in areas with extensive arable land, higher population density, and more developed economic activity, where ESs levels were lower. (2) Trade-offs/synergies: The analysis highlighted the prevalence of synergistic effects among ESs, with food provisioning-related services exhibiting notable trade-offs. Trade-off/Synergistic effects were weaker at the grid scale but more pronounced at the sub-basin and county scales, with significant spatial heterogeneity. (3) Identification of ESBs: We identified five distinct ESBs: the HQ-CS synergy bundle (HCSB), the integrated ecological bundle (IEB), the agricultural bundle (AB), the key synergetic bundle lacking HQ (KSB), and the supply service bundle (SSB). These clusters suggest that the overall ecological environment of the study area has significantly improved, the supply functions have strengthened, and ecosystem vulnerability has been effectively mitigated. Building upon the identified multi-scale spatiotemporal heterogeneity patterns of ESBs in the XRB, this study proposes an integrated framework for territorial spatial planning and adaptive land management, aiming to optimize regional ecosystem service provisioning and enhance socio-ecological sustainability.

Wire arc additive manufacturing (WAAM) with a special arc mode of cold metal transfer pulse advanced (CMT-PADV) is an ideal additive manufacturing process for fabricating aerospace components, primarily high-strength aluminum alloys, offering advantages such as high deposition rates and low cost. However, the numerical simulation of the CMT-PADV WAAM process has not been researched until now. In this study, we first developed a three-dimensional fluid dynamics model for the CMT-PADV WAAM of 7075 aluminum alloy, aiming at analyzing the droplet transition and molten pool flow. The results indicate that, under the CMT-PADV mode, droplet transition follows a mixed transition mode, combining short-circuiting and spray transition. The Direct Current Electrode Positive period of the arc accelerates droplet spray transition, significantly increasing molten pool flow. In contrast, the Direct Current Electrode Negative period of the arc predominantly features droplet short-circuiting transition with low heat input and a weak impact on the molten pool. The periodic switching of the current polarity of CMT-PADV mode results in periodic variations in molten pool size and volume, reducing heat input while maintaining high deposition quality. The revelation of this mechanism provides process-based guidance for low-defect, high-performance manufacturing of critical components. Full article

Background: Rhododendron is a globally distributed and extensive genus, comprising over 1000 species. In the southwestern mountains of China, there exists a remarkable diversity of Rhododendron, with Yunnan Province alone harboring more than 600 species. R. decorum Franch. has long been utilized by local communities for its medicinal and edible properties. However, the transcriptional regulation function, medicinal properties, and edibility characteristics of R. decorum Franch. currently lack a solid theoretical basis. Methods: Total RNA was extracted from leaves, corollas and androecium/gynoecium of R. decorum Franch. in Heqing county, followed by the construction of cDNA libraries and the de novo assembly of transcriptomes. Results: A total of 63,050 unigenes were extracted from the flowers and leaf organs of R. decorum Franch. Among these unigenes, 43,517 were predicted to be coding sequences, with 32,690 being effectively annotated. Differential gene expression enrichment was observed among different organs within their respective transcriptomes; notably floral organs exhibited significant defense against plant diseases along with signal transduction functions. Furthermore, during the flower harvesting period, all floral organs exhibited gene enrichment pathways associated with carbohydrate metabolism. Additionally, the stamen and pistil displayed flavonoid metabolism pathways, suggesting their potential applications as functional food or medicine. Conclusions: Our results shed light on plant–pathogen defense mechanisms and the molecular bias of flavonoids biosynthesis on flower organs during the flowering period, which might help to understand the consumption of R. decorum Franch. corollas by the Bai nationality of Heqing county.

This paper critically examines Scheler’s mid-period religious theory, focusing on his pursuit of a harmonious cosmic order and religious experience by integrating Catholic theology and phenomenology. The argument has four key stages. First, I argue that the realization of this cosmic order, which enables communion with both the cosmos and God, relies on three elements: spiritual intuition, love, and faith in God’s reality. Second, I contend that these elements, in turn, originate from God’s self-revelation and divine love, which establish a bidirectional relationship between humanity and God. Third, I demonstrate that this mutuality is deepened through Scheler’s dual-layered cosmic order, which employs analogy and phenomenological intuition to distinguish between the microcosm and the macrocosm. Finally, I identify two critical limitations in Scheler’s framework: his oversimplification of the divine–human asymmetry through analogy and his insufficient treatment of the origins of evil. Therefore, while Scheler’s synthesis offers valuable insights, it necessitates the further exploration of metaphysical and religious questions, particularly those concerning divine transcendence and the nature of evil.

The role of the mosque has become increasingly vital, particularly in contemporary societies such as Britain, where both the place and status of religion in public life are constantly discussed and debated. Indeed, in the contemporary period, the role of the mosque has several dimensions, ranging from a social space, educational and cultural exchange, and community cohesion centre to a knowledge hub. In this context, this paper suggests that a mosque should be seen as an independent religious institution, although these are influenced by and responsive to governments, elites, pressure groups, public bodies, etc. Using a thematic analysis of news items in The Guardian and The Daily Telegraph over a period of two years (8 July 2005–7 July 2007), it finds that in the aftermath of 7/7, the mosque as a religious place and an institution for British Muslims is largely seen as incompatible and a threat to secular British society and that it is linked with radicalisation and terrorism. According to Quranic texts and revelations, it is indeed a fact that mosques are open to all. This is logical since God’s mercy, love, and forgiveness are for all of mankind without any distinction, which is perhaps why the mosque has been the sacred house of God Himself. This study aims to reveal the development of visible hostility in some sections of the British media and political campaigns. Moreover, it intends to trace the determination and idea of the mosque as a religious place and an institution for British Muslims rather than only a place for worship. Finally, this study will argue the role of the mosque in promoting community cohesion and mutual understanding within the Muslim and other faith communities located in Britain. Full article

I consider a class of dynamic Bayesian games in which types evolve stochastically according to a first-order Markov process on a continuous type space. Types are privately informed, but they become public together with actions when payoffs are obtained, resulting in a delayed information revelation. In this environment, I show that there exists a stationary Bayesian–Markov equilibrium in which a player’s strategy maps a tuple of the previous type and action profiles and the player’s current type to a mixed action. The existence can be extended to K-periodic revelation. I also offer a computational algorithm to find an equilibrium. Full article

This study delves into the dynamic behavior of ultra-high-speed rotor systems underpinned by helium hydrostatic gas bearings, with a focus on the impact of rotational velocity on system performance. We have formulated an integrative dynamic model that harmonizes the rotor motion equation with the transient Reynolds equation. This model has been meticulously resolved via the Finite Difference Method (FDM) and the Wilson-Θ technique. Our findings unveil intricate nonlinear dynamics, including 2T-periodic and multi-periodic oscillations, and underscore the pivotal role of first-order temporal fluctuations, which account for over 20% of the transient pressure at rotational speeds exceeding 95.0 krpm. Further, we have executed empirical studies to evaluate the system’s performance in practical settings. It is observed that when the ratio of low-frequency to fundamental frequency approaches 0.3 and the amplitude ratio exceeds 3, the vigilant monitoring of system stability and reliability is imperative. Collective insights from both computational simulations and experimental studies have enriched our understanding of the dynamic attributes of ultra-high-speed rotor systems. These revelations are crucial for the advancement of more efficacious and resilient rotor systems designed for high-speed applications. Full article
