This article explores how cultural representations of outer space in Kazakhstan reflect and shape public debates on the history and legacy of the Soviet cosmos while offering new perspectives on national cosmic imaginaries. Kazakhstan inherited much of the Soviet outer space physical infrastructure, including its most potent artefact, spaceport Baikonur. The article demonstrates that the artistic representations of the cosmic themes provide an important ground for understanding 1) how the cosmic enthusiasm and utopianism of Soviet astroculture have been moulded into a more critical interpretation of outer space and its impact on Kazakhstani society and 2) how the cosmic mythologies of the past have been used for reinventing Kazakho-futurism as an element of the nation’s future. ‘Cosmic art’ offers a unique lens for exploring how cultural representations of outer space contribute to the redefinition of societal conditions and the complexity of becoming a sovereign nation in the twenty-first century.
Low cardiac output syndrome is a leading cause of morbidity and mortality after CHD surgery. Early, transparent risk estimation at paediatric cardiac ICU admission could guide monitoring and resource allocation.
Objectives:
To develop and evaluate a multivariable model that estimates the risk of low cardiac output syndrome using routinely available preoperative, intraoperative, and immediate postoperative variables.
Methods:
In this single-centre retrospective observational cohort, children ≤18 years undergoing CHD surgery between February 2023 and November 2024 were included. Low cardiac output syndrome was defined using prespecified criteria from the Paediatric Cardiac Critical Care Consortium. Candidate predictors were screened in univariate analyses; independent associations were estimated with multivariable logistic regression and backward elimination.
Results:
Among 191 patients, 46 (24%) developed low cardiac output syndrome. Independent predictors were higher surgical complexity ([RACHS-1] ≥ 4; AOR 3.69, 95% confidence intervals 1.38–9.81), preoperative inotrope use (AOR 2.75, 1.02–7.43), longer cardiopulmonary bypass duration (AOR 1.01 per minute, 1.00–1.02), and a greater number of prior cardiac operations (AOR 2.00 per operation, 1.34–2.97); higher operative weight was protective (AOR 0.92 per kilogram, 0.87–0.97). Model performance metrics were AUROC 0.88 and AUPRC 0.71; at a prespecified decision threshold, accuracy 0.82, positive predictive value 0.66, sensitivity (recall) 0.50, F1 score 0.57, and negative predictive value 0.85.
Conclusions:
A parsimonious, interpretable model derived from routinely collected data identifies children at increased risk of low cardiac output syndrome at ICU arrival and can inform early intervention and staffing. Prospective multicentre validation and dynamic updating with continuous postoperative physiology are warranted.
This article investigates multisensory listening, ecological approaches and embodiment in videomusic and audiovisual performance. Rooted in practice-based research, autoethnography and phenomenology, it explores how interactions between sound, image, bodies and intersubjective encounters within the triad of space, place and environment condition transmodal perception. The study identifies scenophony, affect and imagination as constitutive vectors of immersion, highlighting the porosity between physical sites and virtual environments where sensory boundaries dissolve. Synchresis is analysed as a primary mechanism of audiovisual transmodality, while the process of habitation facilitates the transformation of the technical dispositif into a lived place. Texture is established as a foundational compositional principle to organise sensory experience, using the analysis of Nuées (2016) to demonstrate how these dynamics operate through perceptual deviation and transmodal textures in motion. This research defines audiovisual creation as an ecological practice shaped through fluidity, intersubjectivity and situated modes of inhabiting space.
This paper studies the definability of natural language generalized quantifiers. The semantics of generalized quantifiers are provided by a collection of subsets of the underlying domain. However, the generalized quantifiers appearing in natural language are definable either by first-order quantification or by cardinality notions. This paper provides an explanation for this observed phenomenon. The explanation is that the famous constraints of domain independence and conservativity, when extended to Henkin models, suffice to ensure low-level definability, namely $\Delta ^1_1$-definability or at least $\Sigma ^1_1$-definability; and in most cases this definability can be made to be bounded. This is basically a consequence of Feferman’s Preservation Theorem [15], which Marker [46] has provided a short model-theoretic proof of. Further, we verify that the paradigmatic cardinality quantifiers are indeed $\Delta ^1_1$-definable for a reasonable choice of background theory. Finally, in many other cases, we show that this definability can be lowered to first-order definability.
The prioritization of belligerent perspectives at the expense of civilian protection and welfare has a long history in just war theory and practice, from the works of early just war theorists to the legal and scholarly defenses of colonial conquest to the contemporary moral injury discourse. In this article, I show how this history has contributed to the ongoing infliction of devastating harms on civilians, as evidenced in the case studies of drone warfare and the war in Gaza, and I argue for the inclusion and prioritization of noncombatant civilian perspectives in academic, policy, and legal analyses of war. Doing so, as I demonstrate, radically disrupts traditional just war thinking and has important implications for broader social, legal, and policy approaches to armed conflict and its aftermath.
The aim of this review is to describe nutrition strategies that may help to meet the ever-increasing global demand for chicken meat in a sustainable manner. This may include decreased reliance on imported feedstuffs through replacement of imported protein (e.g., soybean meal) with locally available alternatives such as canola or grain legumes, as well as a reduction in crude protein content in feeds through a precision use of amino acids and enzymatic supplements. Challenges, opportunities and research needs associated with alternative feed ingredients are illustrated, and potential risks or benefits to the health of birds, consumers and their environment are discussed. It is concluded that the long-term sustainability of chicken meat requires a multifactorial approach that relies on improved feed formulation practices based on use of local ingredients, reduced crude protein, optimizing feed processing (e.g., particle size), and use of feed additives (e.g., enzymes, synthetic amino acids, pre-and pro-biotics) whilst considering their impact on efficiency of production as well as animal, human and environmental health.
Extreme gust encounters by finite wings with disturbance velocity exceeding their cruise speed remain largely unexplored, while being particularly relevant to miniature-scale aircraft. This study considers extreme aerodynamic flows around a square wing and the large, unsteady forces that result from gust encounters. We analyse the evolution of three-dimensional, large-scale vortical structures and their complex interactions with the wing by performing direct numerical simulations at a chord-based Reynolds number of 600. We find that a strong incoming positive gust vortex induces a prominent leading-edge vortex (LEV) on the upper surface of the wing, accompanied by tip vortices (TiVs) strengthened through the interaction. Conversely, a strong negative gust vortex induces an LEV on the lower surface of the wing and causes a reversal in TiV orientation. In both extreme vortex gust encounters, the wing experiences significant lift fluctuations. Furthermore, we identify two opposing effects of the TiVs on the large lift fluctuations. First, the enhanced or reversed TiVs contribute to significant lift surges or drops by generating large low-pressure cores near the wing. Second, the TiVs play a part in attenuating lift fluctuations through enhanced downwash or upwash, formation of an arch vortex and distortion of vortical structure around the wing corners. The second effect outweighs the first, resulting in smaller transient lift changes on the finite wing compared with the two-dimensional wing. We also show that flying above a positive gust vortex or flying below a negative one can mitigate lift fluctuations during encounters. The current findings provide potential guidance on how TiV dynamics and wing positions could be leveraged to alleviate large transient lift fluctuations experienced by finite wings in severe gust conditions.
Nado.pred že.part! ‘Ça, alors !’ est la manière dont une personne parlant russe pourrait s’exprimer lorsqu’elle est prise de court, lorsqu’elle est frappée de surprise. Cet article propose d’expliquer cet emploi si particulier du modal nado (qui, comme nous le verrons, exprime une forme de nécessité, « il faut ») qui peut, lorsqu’il est utilisé conjointement à la particule énonciative že perdre son expression modale stricte et exprimer alors un ressenti du locuteur à un instant t. Ses usages feront également l’objet d’une analyse et d’une proposition de classification à travers la description d’énoncés russes en contexte.
In cases of isolated left brachiocephalic artery, if both ductus arteriosus remain patent, excessive pulmonary blood flow can occur, and cerebral perfusion may be compromised by a steal phenomenon, potentially leading to cerebral atrophy. We report a case of an isolated left brachiocephalic artery with bilateral patent ductus arteriosus in which transcatheter closure of both ductus arteriosus was successfully performed.
This article explores support for Black Lives Matter through the lens of intergroup conflict and solidarity—concepts at the core of Paula D. McClain’s research. We examine the extent to which expressions of “American identity” amplify support for or opposition to the Black Lives Matter movement. The merits of protest are perceived differently across racial groups in the United States, but theories of superordinate identity suggest attitudes could be unified through common expressions of a shared identity. Using 2016 Collaborative Multiracial Post-Election Survey data (N=3,711; sum of Black and white respondents), we employ multivariate regression analysis to show that although Black and white respondents express similarly strong levels of a superordinate “American identity,” American identity moderates Black and white support for Black Lives Matter inconsistently—and at times in opposing directions. These findings provide additional context for understanding how American identity relates to support for protest activity, suggesting that American identity can assume distinct meanings for different groups of Americans.
By targeting treatment according to molecular biomarkers, precision medicine promises a revolution in health care. We examine this promise by distinguishing three precision medicine strategies: biomarker-stratified high-risk-targeting, biomarker-based individual targeting, and biomarker-based disease targeting. Each strategy seeks to boost one of the determinants of the population impact of a medical intervention. We conclude that these strategies give a molecular coating to decades-old tactics. There is no compelling reason to believe that precision medicine strategies are uniquely effective for sick individuals or sick populations.
This study reconstructs Late Holocene vegetation and Indian summer monsoon (ISM) variability over the past ∼2700 years from the Bandhavgarh Tiger Reserve, located in central India’s Core Monsoon Zone (CMZ). High-resolution pollen data reveal five distinct vegetational phases, with the period between ∼2700 and 2300 cal yr BP characterized by a dense moist deciduous forest dominated by Shorea robusta, indicating strong monsoonal activity. The interval between ∼2300 and 1600 cal yr BP shows four distinct sub-phases: a warm and humid episode (∼2300–2200 cal yr BP), a pronounced dry spell (∼2200–2030 cal yr BP), an ameliorating phase (∼2030–1680 cal yr BP), and renewed monsoon intensification (∼1680–1600 cal yr BP). A moderately strong and stable ISM persisted until ∼820 cal yr BP, followed by a dry, open vegetation regime (∼820–400 cal yr BP) coinciding with increased anthropogenic indicators. Since ∼400 cal yr BP, the resurgence of moist deciduous taxa reflects climatic recovery and forest regeneration. Pollen-based climate reconstructions provide valuable insights into long-term monsoon–vegetation interactions in tropical India.
We investigate the noise reduction performance of a NACA-0012 airfoil at a low subsonic Mach number and a moderate Reynolds number. Noise suppression at the trailing edge is targeted by minimising the wall-pressure jump, which is stipulated by the unsteady Kutta condition. Guided by this principle, we propose an effective trailing-edge configuration capable of significantly suppressing the radiated noise. Numerical results reveal that a pure streamwise-decreasing impedance trailing edge fails to provide effective noise reduction across a broad range of characteristic frequencies; in some cases, it even leads to a significant increase in noise radiation levels. Therefore, we develop an extended trailing-edge (ETE) configuration, which achieves a notable noise reduction of 3.62 dB. This performance is further improved to 4.22 dB with the incorporation of an impedance design, forming an extended impedance trailing edge (EITE). The reduction in radiated noise is accompanied by modifications in the local flow near the EITE, primarily characterised by a decrease of the streamwise and spanwise Reynolds stresses and a rapid decay of coherent structures. With the aid of high-fidelity near-wall data, the distribution patterns of acoustic sources in the wavenumber–frequency space are analysed in detail with insights derived from the Kutta condition, thereby isolating the distinct role of different elements in achieving the desired noise reduction. For the ETE, it is found that noise suppression is attributed to two primary effects: (i) enhanced destructive interference between sound waves scattered by wall sources near the trailing edges, and (ii) a significant suppression of the vortex shedding process, particularly as evidenced by the distribution of near-field longitudinal process sources. Furthermore, extra noise attenuation is attained by the use of EITE, as the impedance surface leads to a lower convective velocity of pressure fluctuations and reduced energy within the supersonic phase speed region, consequently contributing to a lower scattering efficiency.
We show that there exist constants $\delta _1,\delta _2\gt 0$ such that if $G$ is an $(n,d,\lambda )$-graph with $\lambda /d\le \delta _1$, then $G$ contains an induced cycle of length at least $\delta _2n/d$. We further demonstrate that, up to a constant factor, this is best possible. Utilising our techniques, we derive that the number of non-isomorphic induced subgraphs of such $G$ is at least exponential in $n\log d/d$, and further demonstrate that this is tight up to a constant factor in the exponent.
