On December 1, 2023, the International Court of Justice (ICJ) delivered a unanimous order on provisional measures in Arbitral Award of 3 October 1899 (Guyana v. Venezuela) (Provisional Measures Order). The ICJ indicated two provisional measures. It ordered first that, pending a final decision in the case, Venezuela shall refrain from taking any action that would modify the situation that currently prevails in the relevant disputed territory (the current situation being that Guyana administers and exercises control over the territory) and, second, that both states shall refrain from any action that might aggravate or extend the dispute before the ICJ.
A novel selective mode decomposition, proper orthogonal decomposition and dynamic mode decomposition methods are used to analyse large-eddy simulation data of the flow field about a NACA0012 airfoil at low Reynolds numbers of $5\times 10^4$ and $9\times 10^4$, and at near-stall conditions. The objective of the analysis is to investigate the structure of the laminar separation bubble (LSB) and its associated low-frequency flow oscillation (LFO). It is shown that the flow field can be decomposed into three dominant flow modes: two low-frequency modes (LFO-Mode-1 and LFO-Mode-2) that govern an interplay of a triad of vortices and sustain the LFO phenomenon, and a high-frequency oscillating (HFO) mode featuring travelling Kelvin–Helmholtz waves along the wake of the airfoil. The structure and dynamics of the LSB depend on the energy content of these three dominant flow modes. At angles of attack lower than the stall angle of attack and above the angle of a full stall, the flow is dominated by the HFO mode. At angles of attack above the stall angle of attack the LFO-Mode-2 overtakes the HFO mode, triggers instability in the LSB and initiates the LFO phenomenon. Previous studies peg the structure, stability and bursting conditions of the separation bubble to local flow parameters. However, the amplitude of these local flow parameters is dependent on the energy content of the three dominant flow modes. Thus, the present work proposes a more robust bursting criterion that is based on global eigenmodes.
Soil available phosphorus (SAP) and potassium (SAK) are indispensable for crops, and their stocks are important for food production needed for a growing global population. This study analysed 991 soil profiles across a large part of Romania covering forestland, grassland and cropland in almost all ecological regions. This study investigated SAP and SAK stocks for different soil depths and characterized their magnitude and variability within land uses under different environmental ecosystems, soil classes and soil types, for a better soil and land management under a temperate-continental climate. Cropland soils present the highest SAP and SAK stocks. Chernozems, Phaeozems and Vertosols possess the highest SAP and SAK stocks in Romania, representing the largest country's pool. Both SAP stocks and SAK stocks are significantly correlated with basic environmental properties, existing direct correlations between SAP, SAK, soil organic carbon (SOC) and total nitrogen (TN) stocks. For all land uses, SAP and SAK stocks correlated significantly and directly with each other, as well as with annual temperature, clay content, pH and sum of base cations, and inversely with altitude, slope and annual precipitation. The best predictive values using multiple regression models and basic environmental driving factors were found for forestland stocks of SAP and SAK, followed by grassland stocks, while the lowest prediction occurred for cropland stocks, probably due to the long-term additional nutrient input performed by farmers in cropland that changed the natural conditions otherwise present in grassland, and especially in forestland. Based on these results some management measures are discussed.
Photography may seem primarily a technology of image-making, but it was in fact a powerful mode of meaning-making in the nineteenth century, and its operation as such was actively under negotiation from its invention. This essay examines the photograph's status as both documentary object and artistic expression, drawing on examples including journalistic, political, and familial uses of the medium as well as the forms of entertainment it provided. As a force of knowledge production—whether helping consolidate emerging sentimental ideals of family relations, forwarding anthropological understandings of the world, or supporting the work of spiritualists claiming to commune with the dead—photography was used to clarify and shape people's ideas about phenomena they did not understand and often otherwise could not see. As such, it became a vital infrastructure for the transmission of culture and the consolidation of national identity.
What happens when someone ignorant of their Jewish heritage uncovers the truth in dramatic circumstances? This article focuses on and advocates for further analysis of an unstudied discrete phenomenon: ‘the moment of discovery’ in early twentieth century Germany and Austria. The article's four empirical sections analyse various facets of this moment: the clues which pointed towards the Jewish ancestral secret, missed by many non-Jewish ‘Jews’; the reaction of antisemites to becoming the object of their own hatred complex; the deep despair felt during the moment of discovery; the mitigatory actions which could ameliorate the latter; and the minority who reacted positively to the news. Collectively, the piece displays the terror associated with being ‘Jewish’ at the time, the extent to which non-Jewish ‘Jews’ were truly separated from the Jewish community and, crucially, the radicalisation of moments of discovery under Nazism, when they became more devastating than ever.
The drive toward precision, punctuality, and an accurate global mapping of the ocean has always been in tension with the forces that undermine and undercut the attempt: human failure, bad weather, broken instruments, bad luck, and so on. The serial labor of embedding infrastructure is risky and requires both improvisatory skills and persistence. The ships that paid out the telegraph cable, and the many kinds of serial writing that took place onboard these ships, were all part of the infrastructural endeavor of the nineteenth century, and they anticipated the digital as much as the cables did themselves. If we think of their role as actively and serially remaking positionality in this uneven imperial world, we can think of serial data produced onboard moving ships in the nineteenth century as shaping an infrastructure that powerfully anticipates the digital.
This case is a 4-month-old patient with Kawasaki disease who showed coronary artery lesions after a disease relapse. Following the guidelines from the Randomised Controlled Trial to Assess Immunoglobulin plus Steroid Efficacy, the patient initially saw an improvement in symptoms. However, a relapse occurred despite low levels of C-reactive protein, leading to significant coronary artery growth. Treatment with a third dose of intravenous immunoglobulin and cyclosporine led to a slow reduction in the size of the coronary artery abnormalities. This case highlights the difficulty in monitoring Kawasaki disease progression through clinical symptoms and C-reactive protein levels alone. We also emphasise the necessity of echocardiographic monitoring in patients receiving anti-inflammatory treatments, including steroids, because coronary artery problems can arise or continue without the usual signs of Kawasaki disease or increased C-reactive protein levels.
Functional MRI (fMRI) has proven valuable in presurgical planning for people with brain tumors. However, it is underutilized for patients with epilepsy, likely due to less data on its added clinical value in this population. We reviewed clinical fMRI referrals at the QEII Health Sciences Center (Halifax, Nova Scotia) to determine the impact of fMRI on surgical planning for patients with epilepsy. We focused on reasons for fMRI referrals, findings and clinical decisions based on fMRI findings, as well as postoperative cognitive outcomes.
Methods:
We conducted a retrospective chart review of patients who underwent fMRI between June 2015 and March 2021.
Results:
Language lateralization represented the primary indication for fMRI (100%), with 7.7% of patients also referred for motor and sensory mapping. Language dominance on the side of resection was observed in 12.8% of patients; in 20.5%, activation was adjacent to the proposed resection site. In 18% of patients, fMRI provided an indication for further invasive testing due to the risk of significant cognitive morbidity (e.g., anterograde amnesia). Further invasive testing was avoided based on fMRI findings in 69.2% of patients. Cognitive outcomes based on combined neuropsychological findings and fMRI-determined language dominance were variable.
Conclusion:
fMRI in epilepsy was most often required to identify hemispheric language dominance. Although fMRI-determined language dominance was not directly predictive of cognitive outcomes, it helped identify patients at low risk of catastrophic cognitive morbidity and those at high risk who required additional invasive testing.
Oral traditions describing details of ancient volcanic eruptions and their effects survive throughout the inhabited world. Many such eruptions, especially those having catastrophic environmental and societal consequences, proved sufficiently memorable to form the basis of enduring oral traditions. Using global databases, we identified 2306 such eruptions from 477 inhabited locations that occurred before the start of the Common Era (CE) and are therefore likely to have been the subject of oral traditions. Of these, we selected 20 events (‘remembered’ Holocene eruptions) for which there are extant oral (-derived) traditions that demonstrate how such traditions can reveal details of past volcanism that often are undetectable by retrodictive geoscientific enquiry. We also selected 20 events (‘forgotten’ Holocene eruptions) about which no oral traditions are known and discuss the possible reasons for this. Such oral traditions, while often challenging for conventionally trained geoscientists to interpret, are valuable yet largely overlooked sources of information about the nature and effects of Holocene volcanism that can usefully complement geoscientific enquiry. In particular, we identified locations where memories of such volcanism appear ‘forgotten’ in the hope that scientists might focus their attention on revealing, identifying, and analyzing local traditions.
In the Victorian era, innovations in infrastructure, notably the revolutionary stagecoach, redefined women's travel experiences and offered them a means to break free from domesticity. While the rapid pace of the stagecoach initially unsettles individuals like Jane Eyre in Charlotte Brontë's Jane Eyre (1847), she accustoms herself to its motion to evade perilous situations. Bearing in mind the cadence of the stagecoach, I suggest that Patricia Park's modern retelling of Jane Eyre, Re Jane (2015), adapts the rhythm of the coach by recasting it as the motion of the New York City subway. Revising in this way, Park incorporates positive racial representation through the subway and its passengers. By re-creating the rhythm of the coach through the subway train, Park considers two historical ideas: the New York City subway was built by racial and ethnic minorities such as Irish immigrants and African Americans, and the subway also softly calls back to the beginnings of the American transcontinental railroad that erased the visibility of Chinese immigrant laborers. This essay contends that the transportation systems in nineteenth-century England and twenty-first-century New York created changes that liberated women from the rooted domestic ideologies of their respective periods.
Municipal solid waste management shapes public life at every moment, and it did so for the Victorians as much as it does for us today. Victorians were concerned about the sanitary risk unruly trash posed, but profit, not conservation or fear of hazardous waste, was the primary motivator behind all Victorian municipal waste management. Though the Victorian period is often characterized as a time when government and public works were becoming centralized, this was not the case with municipal solid waste management. Instead, a focus on the individual pursuit of profit meant that Victorian waste management was dispersed across society, with homemakers, recycling entrepreneurs, dustmen, and the very poorest members of society all playing a role. The structures Victorians built (or failed to build) to attend to their trash can help us understand how they ordered society. Waste management practices provide a microcosm of nineteenth-century British capitalism, class, gender roles, and imperial nationalism.
Attempts to use artificial intelligence (AI) in psychiatric disorders show moderate success, highlighting the potential of incorporating information from clinical assessments to improve the models. This study focuses on using large language models (LLMs) to detect suicide risk from medical text in psychiatric care.
Aims
To extract information about suicidality status from the admission notes in electronic health records (EHRs) using privacy-sensitive, locally hosted LLMs, specifically evaluating the efficacy of Llama-2 models.
Method
We compared the performance of several variants of the open source LLM Llama-2 in extracting suicidality status from 100 psychiatric reports against a ground truth defined by human experts, assessing accuracy, sensitivity, specificity and F1 score across different prompting strategies.
Results
A German fine-tuned Llama-2 model showed the highest accuracy (87.5%), sensitivity (83.0%) and specificity (91.8%) in identifying suicidality, with significant improvements in sensitivity and specificity across various prompt designs.
Conclusions
The study demonstrates the capability of LLMs, particularly Llama-2, in accurately extracting information on suicidality from psychiatric records while preserving data privacy. This suggests their application in surveillance systems for psychiatric emergencies and improving the clinical management of suicidality by improving systematic quality control and research.
This article examines Rokeya Hossain's “Sultana's Dream” (1905), a short story that pictures a solar-powered utopia governed by women, as a key site for thinking through the entanglements of sovereignty, gender, colonization, and environmental relations as they are articulated through infrastructure. To read infrastructurally in this way, we attend to socio-historical contexts of nineteenth-century Bengali society and to the Victorian imperial roots of early solar inventions, alongside the more modular aesthetics and meaning-making affordances of solar energy. Such a mode of reading makes infrastructure legible as an essential political ground for the maintenance or transformation of socio-ecological relations and reveals the irreducible political, material, and poetic qualities of infrastructures themselves. Texts like “Sultana's Dream” make such configurations visible and open to interrogation, and demonstrate the ways that solar, as infrastructure, energizes new social and political forms—even those yet undreamed.
This review looks back on our experience with acute middle cerebral artery embolectomies in the 1990s, frowned upon by stroke experts at the time, and no match for the newly introduced and proven treatment of acute ischemic stroke with intravenous recombinant tissue plasminogen activator (alteplase). The past several decades have seen dramatic developments in acute cerebral revascularization, the major paradigm shift being in the form of endovascular thrombectomy. Mechanical thrombectomy has moved from the operating room, where we performed it, to the interventional angiography suite armed with ever-improving clot aspiration and retrieval technologies.
Pensions were a means of social provisioning long before they became a cornerstone of state welfare policies in the early twentieth century. The multifarious pension forms that persisted and were reshaped during the Victorian period offer occasions to glimpse how social bonds and obligations across time were imagined and contested. The pensions of Charles Dickens's Bleak House (1852–53) suggest how the infrastructural potential of a form might flicker within the literary text, even as it is unacknowledged and left behind.
There is a growing body of literature calling for the decolonisation of International Relations (IR) theory. This literature, which includes perspectives from the Global South, Indigenous, and feminist approaches, has explained how the colonial thought and White supremacy of early IR scholars like Wilson, Reinsch, and Schmitt shaped the contemporary field and is still reflected in mainstream understandings of core concepts like peace, sovereignty, and security. The need to decolonise IR is well established, but the way to do so is not always clear. This paper explores how engaging with the global politics of Afro-Caribbean Rebel Music serves the decolonisation effort. We can understand Rebel Music as a form of knowledge that emerged in dialogue with, and continues to reproduce ideas embedded in, global and anti-colonial Black approaches to IR theory. Textually and sonically, Rebel Music critiques the nation-state as the primary agent of peace, security, and identity, imagines a transnational Black identity, and is one of the primary forms in which we can hear the voice of the marginalised communicate their understanding of world politics. Engaging with Rebel Music is thus one avenue to decolonising contemporary IR.
