The current study presents an HPSG analysis for deliminative verbal reduplication in Mandarin Chinese. We provide a detailed description of the phenomenon. After discussing reduplication’s interaction with verb classes and aspect markers, we argue that it is better analyzed as a morphological rather than a syntactic process. We put forward a lexical rule for verbal reduplication in Mandarin Chinese, and the different forms of reduplication are captured in an inheritance hierarchy. The interaction between verbal reduplication and aspect marking is handled by multiple inheritance. This analysis covers all forms of deliminative verbal reduplication in Mandarin Chinese and has none of the shortcomings of previous analyses.
We analyse the monetary-fiscal policy mix in post-war Europe, focusing on France and Italy, to trace the historical dynamics of debt and inflation. Using a Markov-switching DSGE model, we identify distinct policy regimes: a Passive Monetary-Active Fiscal (PM/AF) regime before the late 1980s/early 1990s, an Active Monetary-Passive Fiscal (AM/PF) regime associated with central bank independence and EMU convergence, and a third regime marked by the ELB and active fiscal measures aimed at recovery. Simulations reveal that the PM/AF regime in France led to price volatility but stabilised debt, while AM/PF curbed inflation at the cost of rising debt. In contrast, Italy’s procyclical fiscal policy in downturns exacerbated imbalances, aggregate volatility, and low growth. We further assess the implications of policy credibility and uncertainty.
Previous literature has shown that the introduction of homogeneous perforation on plates and cylinders decreases aerodynamic drag. Here, it is shown that the opposite is true for a sphere; drag can increase with porosity. Hollow porous spheres exposed to a uniform free stream are studied experimentally using force and flow field measurements. The parameter space encompasses moderate to high Reynolds numbers ($5 \times 10^4 \leq \textit{Re} \leq 4 \times 10^5$) and porosities ranging from $0\,\%$ to $80\,\%$. The main conclusion is that drag increases with porosity, at super-critical Reynolds numbers, for all studied porosities. At low porosities (less than $9\,\%$), the effect of porosity on drag can be explained by shifts in the separation point. At higher porosities the drag increase cannot be explained by separation shifts, and instead is explained by two competing forms of kinetic energy dissipation: (i) shear on the macro-scale of the body, and (ii) hole losses from flow through the pores. The former generally decreases with porosity, as bleeding flow passing through the body decreases the characteristic velocity difference in the body-scale wake. In a sphere, hole losses increase with porosity sufficiently fast to overcome decreasing body-scale shear losses, in contrast to plates and cylinders where this is not the case. Relatively weak wake vortex structures, and associated low drag coefficient at zero porosity, for a sphere reduce the impact of wake bleeding. Moreover, fluid entering the fore of a sphere can exit perpendicular to the free stream, further reducing wake bleeding while still contributing to hole losses.
This work aims to complement the description of the atomisation process in a typical commercial pressure-swirl atomiser. Conventional characterisation focuses on the final spray, where established experimental techniques allow for measuring spherical droplets in a dilute regime. However, the early stages of atomisation involve distorted liquid structures with complex interface morphology that challenge both experimental and numerical approaches. While numerical simulations with interface-capturing methods have provided access to this region, they currently remain computationally prohibitive to follow the atomisation process until the formation of the final spherical droplets. To characterise the evolving interface morphology, we propose analysing the curvature distribution obtained from both simulations and two-photon laser-induced fluorescence (2P-LIF) imaging. This curvature-based methodology, recently developed to characterise numerical sprays (Palanti et al. Intl J. Multiphase Flow 147, 2022, 103879; Ferrando et al. Atomiz. Sprays 33, 2023, 1–28), is here extended to experimental data. Both approaches are compared with available phase Doppler anemometry (PDA) measurements performed further downstream on spherical droplets. The morphological evolution of the atomising spray is interpreted through curvature statistics, which provide a unified framework applicable to all atomisation stages. When applied to spherical droplets, the curvature distribution recovers the conventional drop size distribution, linking early interface deformation to the final spray structure. The birth of this final drop size distribution can thus be observed by comparing the three approaches – numerical simulation limited to the early stage of atomisation, curvature derived from 2P-LIF images limited to two-dimensional (2-D) contour analysis, and PDA measurements of the dilute spray. The results show that curvature properties evolve in a way that can be directly representative of the final spray even at early atomisation stages.
A lattice Boltzmann method is adopted to investigate the breakup of surfactant-free and surfactant-laden droplets in both regular and irregular T-junction microchannels. During droplet neck contraction, the neck thinning shifts from inertia dominated to interfacial tension dominated, causing spontaneous rapid neck collapse due to Rayleigh–Plateau instability. For the regular rectangular microchannels, we find that the prerequisite for the spontaneous breakup of a surfactant-free droplet is that the local capillary pressure in the triggering area exceeds the Laplace pressure difference between the inside and outside of the droplet neck. Results show that the critical neck thickness $\delta _\textit{cr}^{*}$ for the droplet spontaneous breakup increases with increasing height-to-width ratio $\chi$ of the microchannel in both surfactant-free and surfactant-laden systems. The presence of surfactants decreases $\delta _\textit{cr}^{*}$ at the identified $\chi$, while the surfactant effects are gradually enhanced as $\chi$ increases. Subsequently, a constriction section is incorporated into the upper microchannel wall to establish an irregular microchannel. As constriction depth (length) increases, $\delta _\textit{cr}^{*}$ linearly decreases (increases) in the surfactant-free system, while $\delta _\textit{cr}^{*}$ exponentially decreases (linearly increases) in the surfactant-laden system. Four empirical formulas are proposed to predict the values of $\delta _\textit{cr}^{*}$ under varying constriction depths and lengths in the two systems.
Guidelines urge that infected fluid or tissue obtained during surgery be submitted for microbiologic study directly rather than via swab. A prospective study of operative specimens showed concordance in 64.7% of cases with better yield from abscess fluid, but swab cultures sometimes identified important pathogens missed by fluid culture.
The chronology of Late Pleistocene and Holocene aeolian sand activity in midcontinent North America provides important insight into paleoenvironmental change and associated surface processes. Near the limit of Marine Isotope Stage 2 glaciation of the Huron-Erie Lobe (Laurentide Ice Sheet) in south-central Indiana, aeolian sand deposits found along the eastern margin of outwash plains in the East Fork and West Fork White River valleys provide an opportunity to test the causal mechanisms for aeolian sand activity. Twenty-five optically stimulated luminescence ages on aeolian sand and four radiocarbon ages on gastropod shells document two phases of aeolian sand activity. The first phase, between 26 and 19 ka, records deflation from active outwash plains in the East Fork and West Fork White River valleys during and after the local glacial maximum. These ages overlap with the chronology of Huron-Erie Lobe advance into and out of the White River drainage basin based on a radiocarbon-dated slackwater succession. The second phase, between 16 and 12 ka, records reworking of older aeolian sand and outwash during a period of no-analog vegetation during the Bølling-Allerød/Younger Dryas and is in general agreement with the timing of dune activity from previous studies in the Great Lakes region.
Early life stress (ELS) increases the risk of metabolic disorders such as obesity, as well as neuropsychiatric conditions including depression. Adolescence represents a critical window for metabolic programming, particularly under the influence of ELS and poor dietary habits. Animal models of ELS, such as maternal separation (MS180), induce long-term alterations in hypothalamic-pituitary-adrenal (HPA) axis function, glucose metabolism, and emotionality; however, it remains unclear whether this paradigm increases vulnerability to a chronic metabolic challenge. The aim of this study was to evaluate the effects of MS180 on male rats provided with mild fructose in drinking water starting at postnatal day (P) 21. Control and MS180 (3 h daily, from postnatal day 1 to day 14) rats were given a choice of normal water or a 10% fructose solution for 10 weeks, with standard animal facility-reared (STD) animals serving as controls. Innate emotionality was assessed using the forced swimming test. Animals were implanted with a jugular vein catheter and we evaluated fasting glucose, glucose tolerance, and baseline corticosterone (CORT) levels after one week. Our findings showed that only MS180 + Fructose rats showed a decrease in swimming and increased immobility in the forced swimming test, and previously reported effects of MS180 were only observed when performing simple comparisons. MS180 also increased body weight gain, caloric intake, impaired glucose tolerance, and elevated baseline CORT levels; however, these effects were not exacerbated by fructose. These findings suggest that even low-level fructose exposure during periadolescence may exacerbate behavioral, but not metabolic, vulnerabilities induced by ELS.
Animals appear in different kinds of sources in medieval Islam, from the Quran to animal fables and works of belles-lettres. This article benefits from previous research on Islam’s attitude towards animals, specifically from the viewpoint of the ascetic-mystical stream of Islam during its classical stage. It examines animals in early Sufi narrative material from three perspectives. The first is the theological-ethical perspective that both questions Sufi morals in approaching animals and animality as well as the allegorical use of animals to portray the human psyche. The second perspective is the narrative angle that examines narrative tropes that use animals as a literary device to enhance human piety. The third perspective is ontological and it examines animals as active agents and practitioners of Sufi piety who share bonds and cosmic interconnectedness with human devotees. This cosmic interconnectedness implies an encompassing unity of the universe in which both human and non-human beings are able to obtain God’s love and intimacy.
After an introduction that places the topic within a broader framework of studying animals in Islamic culture, the article approaches stories as a substantially significant source for Sufi thought. It then discusses the three proposed perspectives using birds, lions and dogs as case studies.
Human impacts on species and ecosystems are increasing at a drastic rate. Raptors, a group of birds particularly vulnerable due to their ecological traits, are heavily affected by a variety of direct and indirect threats. Identifying important areas used during the breeding season and assessing exposure to main risks is crucial for promoting effective management and conservation strategies. We GPS-tracked 25 Eleonora’s Falcons Falco eleonorae, i.e. 2% of the Italian breeding population from a colony in Sardinia, and identified an Important Conservation Area (ICA) of 8,099 km2. This ICA spans Sardinia (Italy, 83%) and Corsica (France, 17%), with only 29.1% of its area covered by Natura 2000 sites. During the breeding season falcons undertook extensive excursions across both sea and land (females: 159 ± 288, males: 198 ± 391 km), often reaching areas far from the colony and routinely encountering wind farms. In Sardinia, 10.2% of the region’s turbines were within the ICA. Around 53% of the locations during foraging excursions fell within the turbine rotor-swept zone (RSZ), and accelerometer data revealed that peak flight activity of falcons coincided with peak wind intensity, the moment when turbines are most likely to be operational. Overall, results suggested that Eleonora’s Falcons are highly mobile during the breeding season and that wind farms pose a potential threat. To aid in spatial planning and management, especially considering the predicted increase in offshore wind farms in the area, we provide the identified ICA freely available for download.
The right of the accused to a timely trial is a fundamental aspect of the right to a fair trial, regarded as a cornerstone of criminal justice systems worldwide. This article explores how this right can be enforced through writ jurisdiction, with a particular focus on Sri Lanka. By comparing writ jurisdiction in Sri Lanka with that of the United Kingdom and Australia, the article examines how developments in these jurisdictions have recognised delays in proceedings as a form of procedural unfairness, thereby establishing it as a valid ground for invoking writ jurisdiction. While the right to a timely trial is an implied fundamental right in Sri Lanka, the article highlights how the rich Indian jurisprudence on this matter could guide in more precisely defining its scope and developing a legal framework for its protection. Furthermore, the article discusses how the intersection of writ and fundamental rights jurisdictions in Sri Lanka has enabled judicial review of violations of the right to a timely trial by inferior courts. Overall, the article offers valuable insights into expanding writ jurisdiction to ensure the timely resolution of criminal trials in other Commonwealth jurisdictions that, like Sri Lanka, follow English legal principles in judicial review.
The early years of life are crucial for developing cognitive abilities, such as intelligence. This period is marked by rapid brain development, in which nutrition is essential. This study aimed to characterise dietary patterns at age 2 and investigate their association with cognitive performance at ages 6-7. The study used data from the 2015 Pelotas Birth Cohort, Brazil (n=4,275). Dietary intake was assessed using a habitual consumption questionnaire, and patterns were extracted using principal component analysis. Cognitive performance was assessed using the Wechsler Intelligence Scale for Children (4th edition), providing intelligence quotient (IQ) scores. Associations were tested using linear regression models. The unhealthy dietary pattern (characterised by packaged snacks, instant noodles, sweet biscuits, sweets and candies, soft drinks, sausages, and processed meats) was negatively associated with IQ (p <0.001). Exploratory analyses suggest that early-life deficits (low weight, height, or head circumference for age) may amplify the negative effects of unhealthy dietary pattern on IQ (interaction p=0.020). Children with high adherence to this pattern and early-life deficits showed a 4.78-point IQ reduction (95% CI: -7.06; -2.49), while those without deficits had a 2.24-point reduction (95% CI: -3.35; -1.13), compared to those with low adherence, even after adjustments. No significant associations were found between the healthy dietary pattern (characterised by beans, baby foods, fruits, vegetables, and natural fruit juices) and IQ scores. These findings suggest that an unhealthy diet in early childhood may impair cognitive performance, particularly in children with early-life deficits.
The Painel USP de Gêmeos (University of São Paulo Twin Panel) is, based at the Instituto de Psicologia da Universidade de São Paulo. It was formally established in 2017 to advance research on fundamental psychological processes through twin study designs. Our relatively new registry comprises a volunteer sample of 8839 twin individuals, 70% of whom live in Brazil’s Southeast, the region with the highest twinning birth rate (10.64‰) of the country, within a national population of 213 million. Our collaborative research group has expanded to include partners from psychology, dentistry, and medicine at USP, as well as other Brazilian institutions, such as the Universidade Federal do Rio Grande do Norte, Universidade Federal da Bahia, and Universidade Federal do Espírito Santo. We are advancing biobehavioral research in Brazil through innovative methodologies, interdisciplinary collaboration, and international partnerships. All twin participants contribute to multiple studies associated with four datasets employing the same hierarchical identification system for participants and families: the Biorepository, the Physiological and Physical Repository, the Behavioral Repository, and Fonoteca Cesar Ades (FOCA). Future directions include expanding our twin registry across the five regions of Brazil, our research partnerships, promoting genetic literacy, and fostering public engagement.
