This article employs terroir as an analytical framework to examine how a place-specific tea acquired its reputation and contributed to processes of cultural self-fashioning in Song China. Focusing on Fujian’s Beiyuan 北苑 tea—exceptionally well documented in Song sources—it explores the close connections among tea, landscape appreciation, and place-making. Drawing on tea manuals and connoisseur writings, the article shows how literati linked tea quality to both natural conditions and cultural practices, using such associations to articulate refined taste and produce place-based knowledge. The case of Beiyuan tea reveals the emergence of a distinctly Chinese rhetoric of terroir, one that transformed environmental description into a rhetoric that mediated between local expertise and imperial order. Within this framework, place itself came to embody quality, integrating physical environment, cultural identity, and sensory experience.
The problem concerning water wave scattering by a floating breakwater has been an interesting subject of study under linearized water wave theory in the past few decades due to the reason that not only do these structures allow better water circulation to have smaller impact on sediment transport and fish migration, but also their construction is cost effective compared with the bottom founded structures. Modern study observes that thick breakwaters, with their larger and bulkier structure, are more effective at reducing wave energy compared with thin breakwaters. However, recent research reveals that breakwaters that combine both thin and thick parts offer enhanced performance by providing effective wave attenuation and reducing the construction costs. We may mention that these problems are primarily studied when the depth of water is uniform. However, in practice, the bathymetry of the water region is not uniform. This motivated us to study the problem of water wave scattering by a $ \boldsymbol \sqcap $-shaped floating breakwater (which is a combination of thick and thin parts) in the presence of a rectangular submarine trench. For analytical solution of the corresponding boundary value problem, the geometric symmetry of the problem simplifies the mathematical difficulty considerably. For this, the domain of definition is divided into smaller subdomains and by suitable matching conditions at the various boundaries of the subdomains, the corresponding boundary value problem is formulated in terms of two Fredholm-type integral equations. The multi-term Galerkin approximation technique, involving Chebyshev polynomials and ultraspherical Gegenbauer polynomials as basis functions, is employed to solve the integral equations. It is important to note here that the choice of basis functions depends on the types of singularities at the corner of the trench and at the submerged sharp edge of the breakwater. The solutions of the integral equations are then employed to evaluate reflection and transmission coefficients. Graphical illustrations show that the length, width of the trench and the width of the breakwater have definite impact on the reflected wave, transmitted wave and the force on the breakwater. It is observed that the presence of trench produces oscillations in the reflection and transmission coefficients. When the width of the trench is equal to the width of the breakwater, reflection and transmission coefficients show smooth uniform oscillations. However, when the width of the trench and the width of the breakwater are unequal, nonuniform, nonsmooth oscillations in the reflection and transmission coefficients are observed. It is interesting to note that for a particular width of the breakwater, the reflected wave of certain wavelength shows resonating behaviour. Also, with the increase of submerged length of the side wall of the $\large \boldsymbol \sqcap $-shaped breakwater, the horizontal force on the breakwater enhances and the vertical force diminishes. Additionally, it is observed that when the breakwater is present in a water region with a trench, the horizontal force is more than the vertical force. However, when the breakwater is present in uniformly deep water without a trench, the vertical force is more than the horizontal force.
Power loss mechanisms in large wind farms are complex due to the multiscale nature of wind farm aerodynamics. Recent studies based on ‘two-scale momentum theory’ have brought new insights into this field; however, most of them have been limited to idealised wind farm scenarios. To better understand power loss mechanisms in real wind farms, in this study, we extend the framework of the two-scale momentum theory to non-ideal turbine design and layout scenarios, and then introduce simple analytical models to account for the associated power losses. This extension provides a holistic view of how turbine design, layout, operating conditions and atmospheric conditions collectively determine the amounts of different types of power losses in real wind farms, including the losses due to turbine-wake interference (i.e. ‘internal’ power loss) and farm-atmosphere interaction (i.e. ‘external’ power loss). We also present a simple iterative method for calculating the optimal farm induction factor that maximises the overall farm power for a given set of conditions, including the atmospheric boundary layer height. Analogously to blade-element momentum theory playing a key role in wind turbine design optimisation, the present theory may play a key role in wind farm design optimisation.
We propose a novel machine-learning-based turbulence closure framework in which a tensor basis neural network (TBNN) is directly embedded into a Reynolds-averaged Navier–Stokes (RANS) formulation, eliminating reliance on traditional baseline turbulence models. The TBNN is trained to predict the Reynolds stress anisotropic tensor from local invariant inputs and geometry-informed features, including stream function and velocity potential. Its output is processed by a regression model that generates an optimised eddy viscosity field, which is then integrated into the RANS equations as a zero-equation turbulence closure. The framework is evaluated on three turbulent flows over complex geometries: a wavy-bottom channel, a smoothed step and a backward-facing step. Incorporating geometry-informed features significantly enhances model robustness, yielding numerically stable and convergent solutions across all cases. The predicted velocity fields and turbulence distributions closely match large eddy simulation (LES) data, confirming the accuracy of the proposed approach and demonstrating its ability to operate independently of conventional turbulence closures.
In 1519, the German theologian and humanist Johann Eck published an edition and commentary on Pseudo-Dionysius’ Mystical theology. By examining this edition, this article explores the early modern reception of Pseudo-Dionysius and the influences that shaped Eck as a scholar. It categorises these influences into humanism, scholasticism and affective theology, analysing how each impacted his work. This article also argues that the purpose behind Eck’s edition is two-fold: to renew scholastic theology and to revive mystical theology by introducing or recommending it to an audience of scholastic theologians.
Numerical computation of the ideal magnetohydrodynamic (MHD) equilibrium magnetic field is at the base of stellarator optimisation and provides the starting point for solving more sophisticated partial differential equations like transport or turbulence models. Conventional approaches solve for a single stationary point of the ideal MHD equations, which is fully defined by three invariants and the numerical scheme employed by the solver. We present the first numerical approach that can solve for a continuous distribution of equilibria with fixed boundary and rotational transform, varying only the pressure invariant. This approach minimises the force residual by optimising parameters of multilayer perceptrons that map from a scalar pressure multiplier to the Fourier Zernike basis as implemented in the modern stellarator equilibrium solver DESC.
Postsecondary education is at the forefront of preparing the next generation of cultural resource management (CRM) practitioners for the workforce. We conducted a study from 2022 to 2023 to gain perspective on improving postsecondary CRM curricula in order to better prepare students for careers in CRM. Our research included semi-structured interviews of nine key consultants with careers in CRM, along with a survey of the broader CRM professional community in the Pacific Northwest, USA. Results from the research identified the necessary skills for new college graduates, areas where CRM programs could improve their curricula, and various approaches in and out of the classroom that are helpful in training students.
Understanding how prehistoric human groups sustained themselves upon encountering novel island environments is crucial for modelling population movements in key world regions like Southeast Asia. Here, the authors present new radiocarbon dates and isotopic data for human and animal remains recovered from the Neolithic site of Xiying on Haitan Island, on the south-east China coast. The human remains are the earliest yet discovered on the island, their stable isotope ratios revealing a lifelong heavy reliance on marine foods despite the availability of a diversity of terrestrial resources, offering new insights into human adaptive flexibility in maritime environments.
This article aims to demonstrate that the “Alevi Revival,” commonly described as the sudden increase in visibility of Alevis in Turkey in the early 1990s, was actually the result of a decade-long transformation experienced by Alevis in Europe since the late 1970s. This historical contextualization is not entirely novel but is typically only framed in reference to certain milestone events. The present article substantiates this approach based on an analysis of nine issues of Yurtseverler Birliği, one of the earliest Alevi political journals, published from 1982 to 1989 in Berlin and not yet studied. The evolving discourse surrounding Alevism in this journal’s issues provides the earliest substantial evidence for understanding the emergence and evolution of strategies employed to promote the visibility of Alevism from the 1980s to the 1990s. By the end of this period, the strategy of “making Alevism known” had become dominant in defining Alevism in Europe, in contrast to heterogeneous approaches to framing Alevism in Turkey. In this sense, the “Alevi Manifesto,” an open letter published in 1990 in Turkey, and the first Alevi Culture Week, organized a year before in Germany, should be regarded as outcomes of the preexisting context rather than the Revival’s initiation.
Assessment for children with acquired brain injury (ABI) often includes measures of preinjury functioning; however, there is limited understanding of how social determinants of health (SDOH) are associated with preinjury measures. This study investigated the association of the Area Deprivation Index (ADI) with measures of preinjury functioning.
Methods:
196 caregivers of children with ABI completed the Adaptive Behavioral Assessment System-3rd Edition (ABAS-III), and 188 children with ABI completed the Wide Range Achievement Testing-4th Edition or 5th Edition word reading subtest (WRAT-Word Reading). Two linear regressions were performed: 1) ADI × WRAT-Reading and 2) ADI × ABAS-III.
Results:
The ADI demonstrated significant associations with the ABAS-III and WRAT-Reading scores. Children in lower deprivation areas demonstrated higher preinjury functioning and word reading scores.
Conclusions:
These findings have implications for recovery from brain injury, considerations for incorporating social determinants of health into neuropsychological evaluations, and implications for clinician interpretation of a child’s testing.
We report the first streamwise-localised travelling-wave solution in square-duct flow that acts as an edge state in the full phase space, without any imposed spatial symmetries. Performing edge tracking and Newton iteration, we identify a steady travelling wave that possesses a codimension-one stable manifold, which (at least locally) forms the boundary between the basins of laminar and turbulent attractors. Parametric continuation identifies this solution as the lower branch of a saddle-node bifurcation pair. Perturbation analysis places both solutions on the laminar–turbulent boundary and uncovers a heteroclinic connection that links the two branches and is likewise confined to the basin boundary. This symmetry-free, localised edge state expands the catalogue of invariant solutions in wall-bounded shear flows and provides a geometric framework for understanding the transition dynamics in extended systems.
Our study evaluated a large language model (gpt-4o-mini) for surgical site infection (SSI) adjudication, achieving 100% sensitivity but 69.4% specificity. While reducing the manual screening workload by 66%, the agent generated many false positives, underscoring the need for refined models to improve specificity without compromising accuracy.
Knotroot foxtail is a troublesome perennial grass found in pastures across the Southeastern United States. Herbicides such as hexazinone and quinclorac are labeled for control of this weed; however, their efficacy can be inconsistent due to delayed or excessive rainfall, which limits herbicide movement into the soil for root uptake, allowing knotroot foxtail rhizomes to survive and produce new shoots, resulting in reduced control. A greenhouse study was conducted at Auburn University, Alabama, in 2023 and 2024 to evaluate the effect of rainfall timing on the efficacy of quinclorac and hexazinone in controlling knotroot foxtail. Knotroot foxtail plants averaging 28 cm in height were treated with quinclorac (0.4 kg ae ha-1) or hexazinone (0.8 kg ai ha-1), followed by simulated rainfall (6.3 mm) applied at 0, 3, 6, 9, 12, and 15 days after herbicide treatment. Hexazinone provided greater knotroot foxtail control and rhizome biomass reduction than quinclorac. At 51 days after each rainfall treatment (DAERT), hexazinone provided 90% control, compared with 76% with quinclorac. In 2024, at 51 DAERT, control with hexazinone ranged from 99% to 92% when rainfall occurred within 0 to 6 days after application, but declined to 85% and 81% when rainfall was delayed until 12 and 15 days, respectively. Similarly, quinclorac-treated plants achieved 87% to 77% control when rainfall occurred within 0 to 9 days, but control dropped to 67% to 62% with delayed rainfall at 12 to 15 days. Relative to the nontreated control, hexazinone and quinclorac reduced knotroot foxtail rhizome biomass by 72% and 42%, respectively. Early rainfall (0 to 6 days) after herbicide application enhanced knotroot foxtail control, while delayed rainfall reduced herbicide effectiveness. This study underscores the importance of the timing of application when hexazinone or quinclorac is used for knotroot foxtail management before precipitation events.
Pneumocystis jirovecii pneumonia is a serious opportunistic infection in immunocompromised individuals. Despite recognized person-to-person transmission and healthcare-associated outbreaks, optimal infection control strategies remain unclear. The COVID-19 pandemic led to the implementation of universal masking and physical distancing in hospitals, providing a unique setting to observe P. jirovecii transmission under stringent “droplet precaution”-like conditions. This study investigated healthcare-associated P. jirovecii transmission between June 2020 and November 2021.
Design:
Retrospective cohort study.
Setting:
One tertiary-care hospital in Montréal, QC, Canada.
Patients:
All patients with P. jirovecii pneumonia at our institution during that period.
Methods:
Cases were identified via laboratory data and chart review. P. jirovecii-positive samples underwent genotyping using multilocus sequence typing. A transmission map was constructed based on shared genotypes and spatiotemporal overlap of hospital visits within a defined window of potential exposure.
Results:
Twenty-eight P. jirovecii pneumonia cases were identified. Genotyping succeeded at providing a distinct sequence type (ST) in 21 cases, revealing 7 patients with shared genotypes (3 with ST52, 2 with STX7, 2 with ST19). The transmission map of 12 patients with shared or unknown genotypes revealed 34 same-day and 34 within-one-day contacts, exclusively within outpatient clinics and imaging facilities. Three spatiotemporal clusters of plausible healthcare-associated transmission were identified despite universal masking.
Conclusion:
The occurrence of plausible healthcare-associated P. jirovecii transmission despite stringent universal masking suggests that traditional “droplet precautions” alone may be insufficient to prevent spread, supporting airborne transmission. Infection prevention strategies may need to be expanded in high-risk settings and should account for airborne transmission.
As gauged by the factors usually believed to determine legislative success with Congress—party control, seat share, and presidential approval—President Trump was situated similarly during the first years of each of his terms. Yet, he achieved substantially greater legislative success in 2025 than in 2017. This contrast indicates that the conventional explanatory factors no longer fully capture what drives presidential success in an era of intense party polarization. Instead, intraparty dynamics and legislative strategy have an important role in shaping outcomes under unified government today. Understanding contemporary presidential effectiveness requires looking beyond seat shares and public opinion to the internal politics of the governing coalition.
