Quantum technologies have the potential to play a significant role in future technological and economic advancement. However, our understanding of the specific narratives and topics present in national quantum technology policies is limited, even though these policies are vital for shaping global strategies, progress, and responsible development in the field. In this study, we use narrative policy analysis together with computational topic modeling to examine 55 governmental documents from 24 countries, covering over a decade. Using BERTopic modeling and the Narrative Policy Framework, the results reveal that national initiatives primarily focus on technological leadership for security and economic prosperity, assessing technological readiness, and, to a lesser extent, commercialization, and societal impacts. Over time, we see a trend toward greater alignment in the prevalence of these narratives, with different themes beginning to be considered more equally. Nevertheless, the narrative surrounding responsible quantum development and societal implications remains the least represented. The study shows the strategic priorities of the analyzed countries and introduces an innovative method for analyzing policy texts. Based on the results, we recommend a balanced regulatory approach for quantum technologies that promotes ethical innovation, supports inclusive technological ecosystems, and encourages global collaboration. Furthermore, we caution that an excessive emphasis on leadership and competition may lead to isolated innovation systems that could hinder progress, cooperation, and joint efforts.
Let $p$ be an odd prime, and let $E_1$ and $E_2$ be two elliptic curves defined over a number field $K$, with good ordinary reduction at $p$. We compare the $\Lambda$-ranks and (generalized) Iwasawa invariants of the Pontryagin duals of the Selmer groups of $E_1$ and $E_2$ over ${\mathbb{Z}}_p^d$-extensions $\mathbb{L}_\infty$ of $K$ for general $d \ge 1$ under the hypothesis that $E_1[p^i] \cong E_2[p^i]$ as Galois modules for a sufficiently large $i$. This generalizes and complements previous work over ${\mathbb{Z}}_p$-extensions. The comparison of generalized Iwasawa invariants is related via an up-down approach to the comparison of the variation of classical Iwasawa invariants over the ${\mathbb{Z}}_p$-extensions of $K$ which are contained in $\mathbb{L}_\infty$.
Dynamic stall on aerofoils is an undesirable and potentially dangerous phenomenon. The motto for aerodynamic systems with unsteadily moving wings, such as helicopters or wind turbines, is that prevention beats recovery. In case prevention fails or is not feasible, we need to know when recovery starts, how long it takes, and how we can improve it. This study revisits dynamic stall reattachment to identify the sequence of events during flow and load recovery, and to characterise key observable features in the pressure, force and flow field. Our analysis is based on time-resolved velocity field and surface pressure data obtained experimentally for a two-dimensional, sinusoidally pitching thin aerofoil. Stall recovery is a transient process that does not start immediately when the angle of attack falls below the critical stall angle. The onset of recovery is delayed to angles below the critical stall angle, and the duration of the reattachment delay decreases with increasing unsteadiness of the pitching motion. An angle of attack below the critical angle is a necessary but not sufficient condition to initiate the stall recovery process. We identified a critical value of the leading-edge suction parameter, independent of the pitch rate, that is a threshold beyond which reattachment consistently initiates. Based on prominent changes in the evolution of the shear layer, the leading-edge suction, and the lift deficit due to stall, we divided the reattachment process into three stages: the reaction delay, wave propagation and the relaxation stage, and extracted the characteristic features and time scales for each stage.
We construct various novel and elementary examples of dynamics with metric attractors that have intermingled basins. A main ingredient is the introduction of random walks along orbits of a given dynamical system. We develop the theory and use it in particular to provide examples of thick metric attractors with intermingled basins.
“Labor” as a specific domain of embodied experience and a source of imagery and figurative language in early China remains understudied. The study invites critical attention to this topic, focusing on four types of imagery of labor—plowing, weaving, fishing, and hunting—which constituted an interpenetrated rhetorical body sustaining varying socio-political and intellectual agendas. Either foregrounded with expressive rhetorical figures like metaphor and allegory or sedimented in commonplace language, the four types of labor imagery emerged and proliferated to present a constellation of moral, epistemic, and aesthetic values toward the characterization of specific practices of ruling, learning, speaking, and writing, as well as the intellectual agency thereof. This rhetorical phenomenon emerged in pre-imperial China and gained new prominence during Han times. Especially since the first century bce, the four tropes of labor were made particularly useful to characterize a growing body of intellectual labor, which was increasingly engaged and coupled with literary learning and production in a manner of self-oriented accumulation and manifestation. This change worked in concert with a forcefully emerging and proliferating literary culture, as well as its embedded scholarly aesthetics and ideology.
The entry into force of the amendments to the International Health Regulations 2005 (IHR 2005), on September 19, 2025, represents a pivotal moment in global health emergency governance history.1 The COVID-19 crisis revealed the inability of both developed and developing nations to protect their populations from the pandemic. Developing nations experienced disproportionate impacts due to insufficient financial resources and manufacturing capacity to obtain necessary health products for pandemic response.2 The neoliberal emphasis on economic efficiency and enforced trade liberalization through the World Trade Organization (WTO) framework, particularly mandatory product patent protection under the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS) widened inequities in access to vaccines, therapeutics and diagnostics (VTDs), and increased dependency of developing countries on developed countries for this access.3
Explore the relationship between the severity of psychological distress symptoms and COVID-19-related bereavement, along with various sociodemographic factors and smoking/substance use behaviors during the COVID-19 pandemic.
Methods
This study used 962 Missouri residents’ (age: mean 44.8, SD 16.7, range 18-86 years; 67% [641] female) responses in the context of COVID-19 during 2022. Severity of psychological distress was measured using combined responses from PHQ-8 and GAD-7 scales and classified as moderate to severe using a cutoff score of ≥15 in PHQ-8 or ≥10 in GAD-7 scale. Predictors were bereavement (yes/no), current smoking (yes/no), and any substance use and polysubstance use (≥2). Logistic regressions adjusted for age, highest educational level, and employment status.
Results
Approximately 19% experienced loss due to COVID-19; 28% exhibited moderate to severe symptoms of psychological distress. Individuals who experienced COVID-19-related deaths were more likely to suffer from moderate to severe psychological distress symptoms (Adjusted Odds Ratios (AOR): 1.46; 95% CI:1.00, 2.12). Smoking (AOR:1.68; 95% CI: 1.20, 2.36) and polysubstance use (AOR: 2.44; 95% CI: 1.64, 3.65) also exhibited higher odds.
Conclusions
COVID-19 bereavement and smoking/substance use were linked to higher distress. Future research and strategies should integrate bereavement supports with substance-use screening/brief intervention in disaster mental-health services.
In recent years, the controversy between legal positivists and their opponents has been reframed as a debate on whether ‘legal facts’—aka facts about the ‘content of the law’—are determined by social or moral facts. This new framing ought to be resisted, for two reasons. First, it is biased against legal positivism, by making it the default picture that the ‘content of the law’ is not a set of legal norms atomistically individuated—which is essential to positivism—but a set of ‘facts’ (“the fact that Jones legally ought to pay $35 to Smith”) which can then be grounded holistically in moral facts. Second, talk of ‘legal facts’ has been instrumental in the recent metaphysical turn in jurisprudence, especially in the growing literature on grounding and law. Jurisprudes—of all stripes—should resist it, as it impoverishes and obfuscates many important philosophical questions about law.
The incorporation of algorithmic systems into organizations is reconfiguring decision-making processes and raising new ethical challenges related to transparency, impartiality, and accountability. This study maps the field of algorithmic ethics in organizational contexts through a co-citation–based bibliometric analysis of 1,437 Web of Science publications (search conducted on August 20, 2025). The analysis identifies 12 thematic clusters and reveals a robust intellectual structure, with high modularity (Q = 0.726) and a high weighted mean silhouette value (S = 0.894). The findings highlight the centrality of algorithmic management, responsible artificial intelligence, and explainability, as well as bridging works that connect technical, normative, and management-oriented perspectives. The study advances an integrative conceptual model and a future research agenda that point to the emergence of algorithmic ethics as an institutional logic of organizational governance. For managers, the results underscore the need to embed algorithmic ethics within organizational decision-making and control systems.
This is the first multimodal analysis of a real—not mock or hypothetical—jury deliberation and consists of two parts. The first part investigates the interactive contours of laughter and how it integrates with co-speech gesture to provide an authoritative stance to the juror’s narrative. The second part examines the multimodal interplay among poetics, gesture, and stance in pursuit of justice during deliberation. Rather than consider justice as an abstract or theoretical concept I demonstrate how it circulates in and through embodied conduct.
Intrinsically disordered proteins (IDPs) and disordered regions of folded proteins (IDRs) perform a plethora of cellular functions involving interactions with a variety of proteins, DNA, and RNA. Their flexibility enables them to interact with different cellular components. They can adopt molten globule as well as extended statistical coil structures depending on their amino acid residue sequence. They are generally more enriched in polar and charged residues, which generally facilitate solvation. This review article asks to what extent water as a solvent affects local (on a residue level) and global properties (size, Flory exponents) of IDPs. It introduces various aspects of protein hydration in the folded state as a benchmark and reference. The results of experimental and computational studies on short model peptides reveal how local structural propensities of residues are determined by water–backbone and water–side chain interactions. Ramachandran plots of individual amino acid residues are side-chain and neighbor-dependent. For unfolded oligo-peptides and IDPs (IDRs) the article discusses the intricated relationship between IDP hydration and global parameters (i.e., radius of gyration), which involves multiple parameters such as net charge, charge distribution, hydrophobicity, and the ionic strength of the aqueous solution. A review of experimental work that explored the strength of water–protein interactions and their influence on water dynamics reveals significant differences between water binding to folded and disordered proteins. Finally, The role of water in liquid–liquid mixing of short peptides and IDPs is delineated, which can lead to gelation and the formation of membrane-less droplets.
Some philosophers and legal theorists believe that certain fundamental normative phenomena cannot be adequately explained without appeal to second-order reasons—that is, reasons to act (or not to act) for certain reasons. Others are resistant to such an appeal. This resistance takes a robust form in the Credit Argument, which holds that, since we cannot act for a reason for a reason, the very idea of second-order reasons must be incoherent. In this paper, I do several things. Firstly, I clarify in just what sense the Credit Argument supposes it is not ‘possible’ to act for a reason for a reason. Secondly, I propose a novel typology of second-order reasons. Thirdly, using these insights, I demonstrate that the Credit Argument is weak at several points and should therefore be roundly rejected. This amounts to a partial defence of the appeal to second-order reasons in the explanation of fundamental normative phenomena.
Over the past 10 million years, coastal-marine settings along the Peruvian Margin have undergone profound geographic and oceanographic transformations, resulting in extensive changes in coastal-marine communities. While mollusk taxonomy research is slowly being integrated into ecosystem-wide analyses, which have historically centered on vertebrates, a long-term chronostratigraphically controlled analysis of molluscan diversity and compositional changes has not been undertaken for this region. We compiled a database covering 152 species, 97 genera, and 51 families of mollusk fossils from the Peruvian Margin (13–16°S) to assess long-term diversification patterns and faunal turnover from the late Miocene to the present. We identified two distinctive molluscan assemblages. The first, dating to the late Miocene (10–6 Ma), underwent a substantial shift during the Mio-Pliocene transition (6–4 Ma), culminating in a second assemblage more akin to modern counterparts. This shift resulted in an increase in diversity, with the younger assemblage (6–0 Ma) exhibiting greater genus richness than the former late Miocene assemblage. The turnover at 6–4 Ma was driven by peaks in bivalve origination (6–5 Ma) along with elevated extinction rates for gastropods (6–5 Ma) and bivalves (5–4 Ma). Ecological analyses revealed that no single ecological trait consistently changed during this interval, indicating that the turnover resulted from a broad reorganization of ecological strategies. We propose that the major molluscan turnover during the late Miocene–early Pliocene is associated with geomorphological changes related to the Andean uplift, the disappearance of semi-embayments, and a sea-level rise.
This article analyzes the parliamentary debates over three Canadian federal laws (2021-2024) on medical assistance in dying (MAID). It explores the factors that influenced Parliament’s decision to expand MAID eligibility to include mental illness in 2021 and to subsequently defer that eligibility on two occasions in 2023 and 2024. We argue that the expansion of MAID to include mental illness was partly driven by a looming judicial deadline and the government’s desire to avoid future Charter litigation, while the deferrals were driven by the perceived lack of readiness from key stakeholders, especially the provinces. This case study identifies broader dynamics of judicial-legislative interaction that can affect policy outcomes, including governments’ attempts at “future-oriented compliance” to pre-empt litigation rather than merely respond to it. It also demonstrates both how judicial deadlines can constrain legislative choice in unforeseen ways and how sunset clauses can foster policy uncertainty.
This article examines how the socio-indexical meanings of dialects/style are reconfigured through two-way parallel migration in Ningbo-Fenghua, China, focusing on the socio-indexical (re)valuation of Putonghua, Ningbonese, and Fenghuanese. Using two-phase matched-guise experiments and interviews, the study traces how mobility patterns and generational positioning mediate these meanings. Results show that, while Putonghua retains institutional prestige, it is often regarded affectively empty. In contrast, Fenghuanese and Ningbonese carry ambivalent, shifting values. Fenghua-born migrants reframe Fenghuanese as a resource for expressing intimacy, trust, and regionalism, while non-migrants view it as outdated. Ningbonese occupies a middle-ground, indexing familiarity, respectability, or obsolescence depending on context. Notably, younger speakers collapse dialectal distinctions, reframing both as ‘old speech’ tied to generation rather than place. These findings challenge Global North models that link indexical revaluation to elite cosmopolitanism, showing instead how meaning-making in the Global South can also emerge through administrative restructuring, regional absorption, and long-standing mobility patterns. (Indexicality, social meaning, Ningbo-Fenghua, migration and language, language attitudes).
The $q$-Weibull distribution, as a generalization of the Weibull distribution, plays an important role in the field of reliability theory, survival analysis, finance, engineering, medical science, etc. In contrast to the Weibull distribution, which is limited to describing monotonic hazard rate functions, the $q$-Weibull distribution offers the flexibility to model various behaviors of the hazard rate function, including unimodal, bathtub-shaped, monotonic (both increasing and decreasing), and constant. In this article, we investigated the stochastic comparison of extreme order statistics derived from independent, heterogeneous $q$-Weibull random variables using various stochastic orderings, including the usual stochastic order, hazard rate order, reversed hazard rate order, and likelihood ratio order. Some of these results are further extended to dependent setups by incorporating Archimedean copulas to model the dependence structure. Finally, we explored the behavior of extreme order statistics when the random variables are subjected to random shocks.
The nonlinear free-surface response of moonpools with recesses is investigated through both experimental and theoretical analyses. A theoretical model is developed to compute the natural frequencies using linearised potential flow theory and eigenfunction expansions. Four moonpool configurations with varying recess lengths are examined experimentally. The analysis reveals that larger recess lengths correspond to increasingly pronounced nonlinear responses. It is also shown that, for an incident wave group with suitable frequency content, the linear moonpool response can be significantly smaller than the second- and third-harmonic components. This effect is attributed to super-harmonic secondary resonance, characterised by $n \omega =\omega _{pq}$ ($n\geqslant 2$ and $p+q\geqslant 1$), where $n$ denotes the super-harmonic order, $\omega$ is the excitation frequency, and $p$ and $q$ are the longitudinal and transverse mode numbers, respectively. Here, $\omega_{pq}$ represents the sloshing frequency of the three-dimensional moonpool. Furthermore, it is found that, as the primary responses increase, cross-flow instability can lead to secondary resonance in non-symmetric modes. This occurs because the double and triple frequencies of the base mode approach the transverse or diagonal sloshing frequencies. Additionally, hard-spring Duffing effects for secondary resonance induced by super-harmonics are observed in cases with recesses, becoming more pronounced as the recess length increases, particularly when $h/l\lt 0.3368$, where $h$ is the water depth above the recess and $l$ is the moonpool length.
Let T be a bounded linear operator on a separable Banach space that satisfies geometric properties similar to those of $\ell ^p,\, p>1$. We prove that the smallest and the largest norm of weak cluster points of all maximizing sequences for T can only take the values $0$ or $1$. The three classes of bounded linear operators emerging from the dichotomy of these extremal norm values coincide with the partition, created by considering the norm-attaining property and if the essential norm equals the norm.
As the Canadian population ages, supporting older adults’ desire to age in their homes and communities is vital. Oasis is an older adult-driven program implemented within naturally occurring retirement communities (NORCs) that fosters social connections to support aging in place. While housing partners provide space for such programs, their perspectives are underexplored.
Objective
This study examined housing partners’ experiences (landlords, owners, superintendents) to understand benefits, barriers, and facilitators of implementing the Oasis in different NORC settings.
Methods
We interviewed 11 housing partners via Zoom and analysed data using thematic analysis.
Findings
Four themes emerged: (i) perceived benefits of Oasis program: building social connections and promoting health among older adults, (ii) transforming the building, (iii) Site Coordinator is the ‘secret sauce’, and (iv) starting up and sustaining Oasis: facilitators and challenges.
Discussion
Findings emphasize expanding NORC-based programs like Oasis and sustaining investment in healthy aging.
The notion of faithful flatness of a module over a commutative ring is studied for two R-modules M arising in functional analysis, where R is a Banach algebra and M is a Hilbert space. The following results are shown:
If X is a locally compact Hausdorff topological space, and $\mu $ is a positive Radon measure on X, then $L^2(X,\mu )$ is a flat $L^\infty (X,\mu )$-module. Moreover:
• If $\mu $ is $\sigma $-finite, then for every finitely generated, nonzero, proper ideal $\mathfrak {n}$ of $L^\infty (X,\mu )$, there holds $\mathfrak {n}L^2(X,\mu )\subsetneq $$L^2(X,\mu )$.
• If X is the union of an increasing family of Borel sets $U_n$, $n\!\in \! {\mathbb {N}}$, such that for each $n\in {\mathbb {N}}$, $\overline {U_n}$ is compact and $\mu (U_{n+1}\setminus U_n)>0$, then $L^2(X,\mu )$ is not a faithfully flat $L^\infty (X,\mu )$-module.
In addition, it is shown that the classical Hardy space $H^2$ is a flat, but not a faithfully flat $H^\infty $-module, which answers a 2005 question of Alban Quadrat.
