This work aims to address two main scientific objectives. First, it seeks to rigorously compare ice thickness estimates from GPR datasets with those derived from various modelling approaches. Second, it examines warm and cold ice areas identified by GPR in relation to 2D thermal modelling performed along selected profiles. The analyses focus on two nearby glaciers in Greenland, surveyed in different years (2014 and 2024) and seasons (August and February) and with different GPR antennas, namely 50 MHz unshielded and 100 MHz shielded. We found that global-scale ice thickness models provide relatively accurate volume estimates at regional scale, while they have limitations in local accuracy, as well as the ice thickness models, especially when the bedrock topography derived from GPR data is complex. 2D thermal modelling results were only partially consistent with warm and cold ice occurrence derived from GPR data, indicating the unique and complex thermal structures of polythermal glaciers with irregular shape and geometry. Due to the differences between the two surveys, we believe that the results are relevant not only to the specific test site, but also to a wider range of geographical and climatic conditions and may provide useful guidance for similar applications.

The resonance constraint holds that something can benefit someone only if it bears a connection to her favoring attitudes. It is widely taken as a decisive reason to reject objective views of well-being since they do not guarantee such a connection. I aim to show that this is a mistake and that felt-quality hedonism about well-being can in fact meet the constraint. First, I argue that the typical way of putting the constraint is misguided in its demandingness. I then introduce alternatives and argue that the most plausible among them are compatible with felt-quality hedonism. I proceed to show that the same considerations which animate traditional resonance concerns motivate another kind of resonance which the hedonist is well-positioned to accommodate. One upshot is that the constraint does not provide us with a reason to favor subjective views of well-being, as they are traditionally formulated, over objective ones.

La critique de John L. Austin contre le représentationnalisme en philosophie de la perception l’a mené à soutenir que les sens sont « muets », c’est-à-dire qu’ils ne nous fournissent aucun contenu conceptuel. Cette thèse a été reprise par Charles Travis et Jocelyn Benoist, qui y voient tous les deux une raison d’abandonner toute conception normative de la perception. Si la thèse du mutisme des sens prescrit en effet un rejet du caractère conceptuel de la perception, le présent article s’efforce toutefois de montrer que la tendance à en déduire que la perception exclut toute norme relève en fait d’une radicalisation de la thèse originale d’Austin.

We investigate semigroups S which have the property that every subsemigroup of $S\times S$ which contains the diagonal $\{ (s,s)\colon s\in S\}$ is necessarily a congruence on S. We call such an S a DSC semigroup. It is well known that all finite groups are DSC, and easy to see that every DSC semigroup must be simple. Building on this, we show that for broad classes of semigroups, including periodic, stable, inverse and several well-known types of simple semigroups, the only DSC members are groups. However, it turns out that there exist nongroup DSC semigroups, which we obtain by utilising a construction introduced by Byleen for the purpose of constructing interesting congruence-free semigroups. Such examples can additionally be regular or bisimple.

There has been substantial research undertaken on the role of a health-promoting diet in depression. Yet, the evidence of the relationship between the Nordic diet and the risk of depression is scarce. This cross-sectional study aimed to assess whether a healthy Nordic diet is associated with depressive symptoms. In total, 2603 men aged 42–60 years from the Kuopio Ischaemic Heart Disease Risk Factor Study were included. Diet quality was evaluated with a healthy Nordic diet score derived from the 4-day food diaries and depressive symptoms with the self-reported Human Population Laboratory (HPL) depression scale. Quade ANCOVA was used to examine the mean values of HPL scores in quartiles of a healthy Nordic diet score. Participants’ mean age was 53 years and BMI 26·8 kg/m2; 31·7 % were current smokers, and 86·9 % were married or living as a couple. The mean healthy Nordic diet score was 12·8 (sd 4·0, range 2–25), and the mean HPL depression score was 1·9 (sd 2·1, range 0–13). The findings suggested that lower adherence to a healthy Nordic diet was associated with higher HPL depression scores after adjusting for age, examination year, daily energy intake, leisure-time physical activity, adulthood socio-economic status, smoking and marital status (extreme quartile difference: 0·33 points, 95 % CI 0·10, 0·56, P for trend across the quartiles = 0·003). The results support the hypothesis that a lower-quality diet increases the odds of having depressive symptoms. However, prospective studies are needed to confirm the association.

Previous research has established various debt thresholds beyond which economic performance deteriorates, but few studies examine these thresholds in the context of ongoing fiscal consolidation efforts. This study investigates the interplay between government debt and fiscal consolidation in Organisation for Economic Co-operation and Development countries from 2000 to 2022. The findings reveal that fiscal consolidation, encompassing reductions in government expenditure and tax increases, results in a notable reduction of 1.366% in the primary fiscal balance and a minor 0.024% decrease in GDP per capita. This study significantly contributes to the literature by clarifying the impact of fiscal consolidation relative to specific debt thresholds and its implications for economic performance. A critical government debt threshold of 31.4% of GDP is identified, beyond which debt negatively affects GDP per capita in the presence of fiscal consolidation. Similarly, a debt threshold of 86.7% is found to have a detrimental effect on the primary fiscal balance in the presence of fiscal consolidation. The study shows for disaggregating government expenditure and taxation, that military spending reduces GDP per capita, while investments in health and education have positive effects. Notably, government consumption expenditure harms GDP per capita. On the fiscal balance side, military and education spending improve fiscal health, whereas government consumption and indirect taxes contribute negatively. The findings underline the importance of targeted fiscal policies, suggesting that prudent government spending, especially in health as well as education, and careful management of debt levels are crucial for maintaining economic stability during fiscal consolidation.

Semantic transparency is usually defined as the extent to which the lexical meaning of a morphologically complex word can be inferred from its structure and constituents. Recent studies have emphasized the need to distinguish two aspects of transparency: relatedness (i.e. the degree to which the meaning of lexical constituents is retained in that of a complex word) and compositionality (i.e. the degree to which the meaning of a complex word is determined by the meaning of its constituents and the way they are combined). In this paper, we investigate the influence of a variety of linguistic factors on both relatedness and compositionality. Our objective is twofold, as we seek to (i) determine more precisely the impact of lexical and morphological properties on transparency and (ii) better understand the distinction between relatedness and compositionality based on their respective determinants. The study focuses on deverbal nouns in French and estimates relatedness and compositionality based on human judgments and computational methods. The results indicate that the frequency and ambiguity of bases and derivatives, as well as the productivity and polyfunctionality of nominalizing suffixes, have different effects on relatedness and compositionality. They confirm the relevance of the distinction between the two aspects of transparency.

This paper presents the design of a phase gradient metasurface lens (MSL) that enables the orbital angular momentum (OAM) beam convergence alleviating the limitations of the OAM beams in far-field wireless communication. An MSL of a specific constitutive electromagnetic parameter, i.e., relative refractive index, in front of a traditional Uniform Circular Array is designed at 10 GHz. In the presence of the lens, the beam converges from 58∘ to 24∘ for +1 and –1 OAM modes. The proposed MSL can also be used for second-order (±2) OAM modes. The experimental verification performed on the laboratory prototype agrees well with the simulated results. The purity analysis also confirms that the OAM beams passing through the lens maintain high mode purity, thereby not disturbing the phase distribution in the corresponding OAM modes. The designed lens can be used in point-to-point and defense communications.

Cet article examine les enjeux politiques et épistémiques de l’intégration des connaissances autochtones dans les systèmes de savoirs occidentaux, en y soulignant les résidus de l’impérialisme culturel. Adoptant une perspective épistémologique sociale et constructiviste, il nuance la vision majoritairement positive de cette intégration en la resituant dans un contexte de rapports de pouvoir historiques et structurels. Malgré ses intentions inclusives, l’intégration risque d’altérer profondément les savoirs autochtones en les soumettant aux cadres occidentaux, nécessitant ainsi une remise en question des structures qui façonnent la production et la validation des connaissances.

Cet article présente une critique des conclusions auxquelles parvient C.Thi Nguyen (2020) dans le neuvième chapitre de Games: Agency As Art, qui met en garde contre les dangers de la ludification (gamification) de l’existence, c’est-à-dire le fait d’introduire des éléments fictifs de jeu dans la vie réelle. En mobilisant d’abord des recherches en neuropsychologie, afin de mettre en lumière les enjeux avec lesquels vivent les personnes neurodivergentes, je dénonce les présupposés capacitistes et l’ignorance neurotypique dont fait preuve Nguyen lorsqu’il aborde la ludification de la vie. Puis, je consolide ma critique en l’appuyant sur un point de vue différent, soit celui de le·a philosophe·sse Quill R. Kukla. Certes, son concept d’enchevêtrement (messiness) permet de remettre en question la vertu nguyenne de bon·ne joueur·euse. Enfin, j’atténue l’argument de Nguyen par rapport à la saisie de la valeur en avançant qu’il vise la mauvaise cible en accusant la ludification de l’existence en elle-même plutôt que les institutions néolibérales qui en instrumentalisent les atouts à des fins capitalistes et vicieuses.

Breeding management in laboratory rodents is challenging, particularly around parturition and the neonatal period, where cage disturbance is often avoided in an attempt to limit neonatal mortality. Nevertheless, cage-side observations and single daily checks frequently underestimate pup numbers born and miss parturition complications. Home Cage Monitoring (HCM) systems are gaining popularity in animal facilities, detecting critical events such as food availability and activity levels. Parturition is a complex event involving specific patterns of behaviour, activity and vocalisations. In this study, audio and video data were collected from parturition events of single-housed C57BL/6J females and breeding pairs housed in a prototype rack with integrated microphones. Vocalisations were detected during parturition in both housing conditions, with minimal vocalisations observed prior to parturition, except for ultrasonic sounds in pair-housed mice (Mus musculus). After parturition, all vocalisations gradually decreased. Despite limitations such as the need for post-event analysis and the focus on a single mouse strain, this study suggests that detecting vocalisations can be a promising basis for developing automated parturition detection. This highlights the potential of HCM systems for improving breeding management and welfare in laboratory rodent colonies.

Existing research has primarily examined coping strategies for dirty work while giving less attention to employees’ satisfaction. Much of this work has considered the phenomenon from an identity perspective, despite its underlying connections to job demands and resources. Drawing on the Job Demand-Resource (JD-R) model, this study investigates the relationship between dirty work and employee satisfaction, with emotional exhaustion as a mediating variable and self-consciousness as a moderator. Data collected from 234 participants in dirty work occupations with a 4-week time lag show that dirty work is positively associated with emotional exhaustion, which negatively impacts job, career, and life satisfaction. The findings further indicate that employees with higher self-consciousness report greater emotional exhaustion, while those with lower self-consciousness experience less emotional exhaustion. These results provide theoretical contributions to the dirty work literature and offer practical implications for mitigating emotional exhaustion in these roles.

Les ingénieurs en IA ont besoin de directives applicables pour l’implémentation de principes éthiques dans leurs solutions technologiques. Mais comment y arriver ? Dans cet article, nous prenons le cas du développement de l’intelligence artificielle explicable (XIA) comme point de départ. Sur le plan des mesures concrètes devant être intégrées à l’IA pour la rendre explicable, nous remettons en question l’approche universaliste. Nous proposons une méthodologie normative pour évaluer les mesures de la XIA adaptées à des contextes spécifiques. Cette approche intègre l’éthique dans le développement de l’IA, offrant ainsi une méthode pragmatique pour les ingénieurs, régulateurs et chercheurs en éthique.

Milk fat is a crucial component for evaluating the production performance and nutritional value of goat milk. Previous research indicated that the composition of ruminal microbiota plays a significant role in regulating milk fat percentage in ruminants. Thus, this study aimed to identify key ruminal microorganisms and blood metabolites relevant to milk fat synthesis in dairy goats as a mean to explore their role in regulating milk fat synthesis. Sixty clinically healthy Xinong Saanen dairy goats at mid-lactation and of similar body weight, and similar milk yield were used in a feeding study for 15 days. Based on daily milk yield of dairy goats and the results of milk component determination on the 1st and 8th days, five goats with the highest milk fat content (H group) and five goats with the lowest milk fat content (L group) were selected for further analysis. Before the morning feeding on the 15th day of the experiment, samples of milk, blood and ruminal fluid were collected for analyses of components, volatile fatty acids, microbiota and metabolites. Results revealed that acetate content in the rumen of H group was greater compared with L group. H group had abundant beneficial bacteria including Ruminococcaceae_UCG-005, Saccharofermentans, Ruminococcaceae-UCG-002 and Prevotellaceae_UCG-3, which were important for plant cellulose and hemicellulose degradation and immune regulation. Metabolomics analysis revealed H group had greater relative concentrations of 4-acetamidobutanoic acid and azelaic acid in serum, and had lower relative concentrations of Arginyl-Alanine, SM(d18:1/12:0) and DL-Tryptophan. These altered metabolites are involved in the sphingolipid signaling pathway, arginine and proline metabolism. Overall, this study identified key ruminal microorganisms and serum metabolites associated with milk fat synthesis in dairy goats. These findings offer insights for enhancing the quality of goat milk and contribute to a better understanding of the regulatory mechanisms involved in milk fat synthesis in dairy goats.

This article examines the 19th-century ‘antiquities rush’ – the frenzy of archaeological digging, scientific expeditions, and straightforward looting of artefacts in the broader Mediterranean – through the framework of international status competition. To do this, I first situate material culture at the foundation of international status-seeking and demonstrate the importance of cultural objects as status symbols for states. I then elaborate two logics of status-seeking that explain why states engaged in massive cultural extraction practices in the early 19th century. The first logic is that of cultural custodianship, where states pursued status as guardians of the cultural heritage of humankind. The second logic is a claim to cultural descendance, where states sought recognition as cultural heirs of classical civilisations. Cultural extraction, therefore, was critical in the establishment of the 19th-century international cultural hierarchy. Echoes of these arguments reverberate today in the competing claims of ownership and restitution of these antiquities. To illustrate these arguments, the article focuses on the international competition between France and Great Britain over the extraction of antiquities, examining in detail the removal of the Parthenon Marbles from Athens at the turn of the 19th century.

We revisit the time evolution of initially trapped Bose-Einstein condensates in the Gross-Pitaevskii regime. We show that the system continues to exhibit BEC once the trap has been released and that the dynamics of the condensate is described by the time-dependent Gross-Pitaevskii equation. Like the recent work [15], we obtain optimal bounds on the number of excitations orthogonal to the condensate state. In contrast to [15], however, whose main strategy consists of controlling the number of excitations with regard to a suitable fluctuation dynamics $t\mapsto e^{-B_t} e^{-iH_Nt}$ with renormalized generator, our proof is based on controlling renormalized excitation number operators directly with regards to the Schrödinger dynamics $t\mapsto e^{-iH_Nt}$.
