Using Large Language Models to Abstract Complex Social Determinants of Health From Original and Deidentified Medical Notes: Development and Validation Study.

Social determinants of health (SDoH) such as housing insecurity are known to be intricately linked to patients' health status. More efficient methods for abstracting structured data on SDoH can help accelerate the inclusion of exposome variables in biomedical research and support health care systems in identifying patients who could benefit from proactive outreach. Large language models (LLMs) developed from Generative Pre-trained Transformers (GPTs) have shown potential for performing complex abstraction tasks on unstructured clinical notes. Here, we assess the performance of GPTs on identifying temporal aspects of housing insecurity and compare results between both original and deidentified notes. We compared the ability of GPT-3.5 and GPT-4 to identify instances of both current and past housing instability, as well as general housing status, from 25,217 notes from 795 pregnant women. Results were compared with manual abstraction, a named entity recognition model, and regular expressions. Compared with GPT-3.5 and the named entity recognition model, GPT-4 had the highest performance and had a much higher recall (0.924) than human abstractors (0.702) in identifying patients experiencing current or past housing instability, although precision was lower (0.850) compared with human abstractors (0.971). GPT-4's precision improved slightly (0.936 original, 0.939 deidentified) on deidentified versions of the same notes, while recall dropped (0.781 original, 0.704 deidentified). This work demonstrates that while manual abstraction is likely to yield slightly more accurate results overall, LLMs can provide a scalable, cost-effective solution with the advantage of greater recall. This could support semiautomated abstraction, but given the potential risk for harm, human review would be essential before using results for any patient engagement or care decisions. Furthermore, recall was lower when notes were deidentified prior to LLM abstraction.

Deep Kinetic Energy Response to the Variability of the Kuroshio Extension

AbstractThe transfer of energy from the upper to deep oceans is a well‐known and challenging subject in physical oceanography. This research investigates the intricate relationship between surface and deep ocean currents. Utilizing nearly 2 years of observations from the Kuroshio Extension System Study (KESS), our study unveils the deep‐ocean kinetic energy response to the Kuroshio Extension (KE) variability. We introduce the Kuroshio Extension Jet Path Index (KEJPI), which identifies two distinct modes of the KE jet on an intra‐seasonal timescale. Our findings reveal a strong correlation (0.73) between KEJPI and the mean kinetic energy of deep‐ocean geostrophic circulation, suggesting that the KE jet's large amplitude meanders have a significant impact on deep‐ocean kinetic energy. Singular Value Decomposition (SVD) analysis further unveils a co‐evolving spatial pattern between upper and lower ocean kinetic energy. We investigate the dynamic vertical coupling (DVC) mechanism by examining the coherent variation among the sea surface height (SSH), 15°C isotherm (Z15), deep pressure anomaly, and abyssal flow. The KE jet migration can induce net divergence and convergence within the water column, which in turn generates deep‐ocean quasi‐geostrophic currents. These currents show a marked increase in kinetic energy, reaching levels three times higher than the background. This DVC‐driven kinetic energy can further cascade into near‐inertial and high‐frequency internal waves, contributing to abyssal mixing. Our study underscores the role of large current system instabilities in transferring energy to the deep ocean and facilitating deep mixing processes.

Microfragmented Adipose Tissue Injection Reduced Pain Compared With a Saline Control Among Patients With Symptomatic Osteoarthritis of the Knee During 1-Year Follow-Up: A Randomized Controlled Trial

PurposeTo evaluate the effectiveness of microfragmented adipose tissue (MFAT) for pain relief and improved joint functionality in knee OA in a randomized, controlled clinical trial with 1-year follow-up. MethodsSeventy-five patients were stratified by baseline pain level, and randomized to one of three treatment groups: MFAT, corticosteroid (CS), or saline control (C) injection. Patients 18 years of age or older, diagnosed with symptomatic knee osteoarthritis, with radiographic evidence of knee osteoarthritis and a visual analog pain scale (VAS) score of 3/10 or greater were included. Patients were excluded if they had any prior intra-articular knee injection, current knee ligamentous instability or an allergy to lidocaine/corticosteroid. The VAS pain scale, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the Knee Injury and Osteoarthritis Outcome score (KOOS) were recorded pre-procedure and at 2 weeks, 6 weeks, 3 and 6 months, and 1 year follow-up. ResultsMFAT demonstrated consistent and statistically significant improvements across all primary outcome measures for joint pain and functionality compared to C. For MFAT, there was a significant improvement over baseline at each follow-up, with median (95% CI) KOOS Pain score changes of 18.1 (11.1, 26.4) at week 2 to 27.8 (19.4, 37.5) at 1 year. For CS, the median KOOS pain score reached a maximum of 22.2 (15.3, 30.6) at week 2, only to level off to 13.9 (-2.8, 29.2), a level not statistically different from baseline, at 1 year. The median changes for C hovered around 6-11 points, with statistically significant improvements over baseline indicating a placebo effect. Similar trends were seen for the WOMAC Pain score and VAS Pain score. ConclusionsIn this study, MFAT demonstrated a clinically significant improvement in primary outcome scores compared with a saline control group, while the corticosteroid group only showed statistically significant improvement compared to the control group at 2 and 6 weeks. This finding indicates that MFAT may be a viable alternative treatment for patients with knee OA that fall into the orthopaedic treatment gap.

Collaborating in future states—Contextual instability, paradigmatic remaking, and public policy

AbstractCollaboration is ubiquitous in public policy life, with its presence and profile determined by prevailing governance conditions. Commitments to globalisation and marketisation in the latter part of the 20th century marked the onset of an era defined by collaboration, between and across tiers and spheres of government, with non‐state actors, and through market and network instruments. Current contextual instability poses questions for dominant public policy paradigms and the existing collaborative settlement. This article explores the challenges presented in the current moment and how policymakers and scholars might navigate them. It focuses on how ideas about economics and security shape public policy, illustrating the paradigm‐shifting impact of economism and securitisation. It argues for the replacement of economism and securitisation by sustainability, sovereignty, and justice and demonstrates the latter's engagement with economics and security and their accounting for what have hitherto been ‘subaltern voices’ in public policy. It discusses the implications for collaboration in relation to future collective action problems, more diverse and disconnected ‘publics’, and a more congested and lower trust policy environment. It highlights the need for collaborative plasticity and pluralistic agency.Points for practitioners Public policymaking is shaped by dominant ideas about economics and security; ideas that become ‘taken for granted’ in policy practice. The prevailing ideas of economism and securitisation are being challenged by contextual changes, globally, regionally, and nationally. This creates space for new ideas to shape future public policy. Ideas of sustainability, sovereignty, and justice offer an alternative framework for public policymaking. These ideas can engage productively with economics and security, and they are also inclusive of a wider variety of ‘voices’ particularly those previously marginalised. Collaboration will remain integral to the success of public policy. However, it will need to adapt to new circumstances. This will include defining new purposes, reassessing its appropriateness, reshaping collaborative scope, scale, and form, and refining collaborative activities. A paradigmatic shift in public policy that highlights sustainability, sovereignty, and justice will require the active involvement of a plurality of actors enabled to contribute new knowledge and contest the status quo.

What is ‘children’s television’ in the streaming era?: Assessing content discoverability through Australian children’s streaming platform fluencies

In line with international trends, increasing numbers of children in Australia use streaming video platforms to watch television on-demand from extensive catalogues. Child viewers thus tend to negotiate platform interfaces organised by algorithmic curation to select content, rather than accessing content via scheduled linear TV. The deeper implications of this substantial shift in child audience habits around television have yet to be robustly reckoned with across scholarly and national policy approaches. Indeed, policy settings in Australia have not kept pace with these transformations, one result of which has been that 84% less Australian content was aired on free-to-air commercial broadcasters in 2022 compared to 2019. Key producer bodies fear the sector is in serious peril and may not withstand the current instability. Given that local children’s television meets Australian children’s best interests by situating them within their own socio-cultural context, the issue has become a site of significant policy, industry, and cultural concern. At this precarious time for the Australian children’s television sector, this article outlines key findings of a mixed method study with Australian children aged 7–9 ( n = 37) and their adult guardians to illustrate how children understand, identify, and discover ‘local’ and ‘children’s’ content on streaming platforms. This child audience research contributes to current policy and scholarly debates around the ‘routes to content’ audiences develop in the streaming era. A focus of our analysis is how and if children find Australian content. Our aim is to shed light on how ‘discoverability’ issues compound the current state of turmoil for the sector. We elucidate children’s digital fluencies with platform interfaces but highlight their limited cultural literacies with the content itself, which poses significant implications for industry and policy strategy around local content discoverability for child audiences on streaming platforms.

Intensified Currents Associated With Benthic Storms Underneath an Eddying Jet

AbstractBenthic storms are episodes of intensified near‐bottom currents capable of sediment resuspension in the deep ocean. They typically occur under regions of high surface eddy kinetic energy (EKE), such as the Gulf Stream. Although they have long been observed, the mechanism(s) responsible for their formation and their relationships with salient features of the deep ocean, such as bottom mixed layers (BMLs) and benthic nepheloid layers (BNLs), remain poorly understood. Here we conduct idealized experiments with a primitive‐equation model to explore the impacts of the unforced instability of a surface‐intensified jet on near‐bottom flows of a deep zonal channel. Vertical resolution is increased near the bottom to represent the bottom boundary layer. We find that the unstable near‐surface jet develops meanders and evolves into alternating, deep‐reaching cyclones and anticyclones. Simultaneously, EKE increases near the bottom due to the convergence of vertical eddy pressure fluxes, leading to near‐bottom currents comparable to those observed during benthic storms. These currents in turn form BMLs with thickness of O(100 m) from enhanced velocity shears and turbulence production near the bottom. The deep cyclonic eddies transport fluid particles both laterally and vertically, from near the bottom through the entire BML and may contribute to the formation of the lower part of BNLs. A sloping bottom reduces both the intensity of the near‐bottom currents and the extent of vertical transport. Overall, our study highlights a significant response of the abyssal environment to near‐surface current instability, with potential implications for sediment transport in the deep ocean.

Current Oscillations and Resonances in Nanocrystals of Narrow-gap Semiconductors

In single colloidal nanocrystals of narrow-gap semiconductors PbS and InSb, current instability in the form of quasi-periodic spikes and current resonance peaks was studied by measuring on a scanning probe microscope and analyzing Current-Voltage Characteristics (CVC). The observed phenomena are explained in models of the wave de Broglie process and Bloch oscillations. Statistically, the percentages of such samples and the parameters of oscillations on the current-voltage characteristic are higher, the larger the size quantization parameter, determined by the de Broglie wavelength. A possible practical use is the generation and recording of terahertz radiation modulated by ultrashort pulses.

Enhancing Financial Security in the Digital Age: Mitigating Risks of Virtual Currencies Through Regulation and Institutional Mechanisms

Abstract The swift rise of virtual currencies (VCs) as financial instruments has raised concerns about their ability to increase risks in the global financial system, especially given the current geopolitical instability. This article examines the connection between virtual currencies and financial security, highlighting the importance of strong economic and financial institutions and mechanisms to ensure the reliability of digital assets. We investigate through an extensive literature analysis the various risks linked to VCs, including market volatility, regulatory inconsistencies, and security vulnerabilities, which are exacerbated by geopolitical conflicts. We then examine how institutions have responded to these concerns, focusing on the proactive actions taken by international organizations and national authorities to reduce possible disruptions. The focus of our paper is the Markets in Cryptoassets (MiCA) law, an innovative legislative framework created by the European Union to standardize VC regulation among member states. We analyse the goals and main provisions of MiCA to evaluate its ability to establish an international benchmark for overseeing virtual currencies, ultimately improving investor safety and market integrity. The paper concludes by discussing the changing role of VCs in the geopolitical sphere and supports flexible and cooperative regulatory strategies to balance the advancement of digital assets with financial security needs.

Investment contract as a basis for obtaining housing: theory and practice problems

The investment contract, as a mechanism that allows you to get housing, is gaining more and more popularity in modern housing construction. This tool becomes key in ensuring access to housing for broad segments of the population and contributes to the development of housing construction. However, along with its advantages, the investment contract causes several problems in both theoretical and practical aspects. In the current economic instability in Ukraine and the difficult financial situation of a large part of the population, the search for affordable and effective ways to realize the dream of owning a home has intensified. In this context, new buildings are especially popular as objects that provide an opportunity to purchase housing during the construction stage. Investment contracts certainly remain among the most profitable in this process. Purchasing at the construction stage allows you to reduce costs as much as possible, and later sell at a higher price when the object is ready for operation, reducing the tax burden. However, having chosen this path, future owners face the risk of an unforeseen situation, since there are almost no guarantees for investors to invest in residential construction without complying with the law or the terms of the contracts. In this context, studying the problems of the theory and practice of the investment contract as a basis for obtaining housing is an urgent task. On the one hand, it is necessary to carefully analyze the theoretical foundations of the investment contract and its place in the system of legal regulation. On the other hand, it is important to consider the practical experience of using this tool, identify the problems faced by participants in housing construction, and propose ways to solve them. In this work, we will reveal the essence of the investment contract as a mechanism for obtaining housing, analyze the theoretical aspects of this issue, consider the practical experience of using investment contracts in housing construction, and identify the main problems that arise in this area. Such an analysis will make it possible to draw conclusions about the effectiveness of using an investment contract as a tool for obtaining housing and to determine directions for further research in this area.

Searching for the Profitability of Energy Crops: An Agroecological–Economic Land Use Suitability (AE-landUSE) Model

The current geopolitical and energy market instability calls for speeding up the EU clean energy transition to increase energy security in all the European regions and make Europe the first climate-neutral continent by 2050. Among renewable energies, modern bioenergy is a promising near-zero-emission fuel for increasing energy security in the heating, electricity and transport sectors while promoting growth and job creation, especially in rural areas. In such a context, energy crops will continue to play a key role. Since agricultural planning is a complex issue, especially when energy crops could compete with food ones, we propose an agroecological–economic land use suitability model (AE-landUSE model) to promote the sustainable use of land resources. The AE-landUSE model was developed by integrating cost–benefit analysis (CBA) and land use suitability analysis (LSA) within geographic information systems (GISs). Tested in the Basilicata region (Southern Italy), comparing two different energy crops (rapeseed and cardoon), the results show the model’s utility in identifying suitable areas for energy crops where the investments will be cost-effective. The proposed model will help decision-makers in energy-agricultural planning to increase energy security sustainably.

Documentation practices of hypogea churches of Ethiopia: the case of Lay Gayint Woreda, South Gondar

PurposeThis study aims to document the hypogea churches in Lay Gayint Woreda, South Gondar, to provide information for future tourism development practices and serve as insurance against loss of value due to unmanaged deteriorative factors.Design/methodology/approachThe study followed a descriptive research design with qualitative research approach. Data were collected through field observations, interviews and written sources examination.FindingsThe study explored the lesser-known hypogea churches, which have significant tourist attraction values, including environmental, historical and architectural significance. However, the use of these potential cultural resources for tourism development is not yet attempted, and their conservation status is found to be critical. This documentation work is significant both for the sake of future tourism development plans and as insurance against looming cultural losses.Research limitations/implicationsThis study did not record the ancient treasures of the churches because of the current political instabilities that hindered the access of data. However, it has implication for the need of an extensive documentation activity to trace the cultural resources in the remote areas of the country for future tourism development and conservation practices.Originality/valueThis paper documented the remote hypogea churches not only for the purpose of future tourism development plan but also as an insurance of their values against unmanaged destructive factors.

Sociological education in Belarus: History and the present time

As has happened more than once in history, today education again needs a clear direction for its development. The whirlwinds of change calmed down, and it became obvious that a lot of good things had been lost: education is essentially conservative, and this is its great advantage. Education shows a path to eternal truths, to understanding the laws of evolution and the world of the mind. The university in this sense is not a place of services, bargain, purchase or sale, it is a temple of science and truth, which by definition cannot be widespread. The university lives its own life but in connection with the state, its history, national traditions and values. The article considers the problems of the transformation of sociological education and institutionalization of sociology in Belarus. The teaching of sociological disciplines began with the opening of the Belarusian State University (BSU) in 1921. Professor S.Z. Katzenbogen became the first teacher of sociological disciplines and the head of the department of sociology and primitive culture. This was followed by a more than a thirty-year forced break due to the removal of sociology from the curriculum, repressions of the 1930s, the Great Patriotic War and post-war reconstruction. The revival of sociology began in the 1960s with the efforts of G.P. Davidyuk and E.M. Babosov. Sociological departments were opened at the Academy of Sciences and leading universities; sociology became one of the main sources of knowledge about the contemporary society and social well-being. Despite all difficulties and obstacles, sociology has become in demand under the current uncertainty, global instability and social turbulence. However, the ignorance of national experience and educational traditions and mechanical borrowing of foreign practices is unacceptable and leads to stagnation.

Long-Term Science Goals with In Situ Observations at the Sun-Earth Lagrange Point L4

The Korean heliospheric community, led by the Korea Astronomy and Space Science Institute (KASI), is currently assessing the viability of deploying a spacecraft at the Sun-Earth Lagrange Point L4 in collaboration with National Aeronautics and Space Administration (NASA). The aim of this mission is to utilize a combination of remote sensing and in situ instruments for comprehensive observations, complementing the capabilities of the L1 and L5 observatories. The paper outlines long-term scientific objectives, underscoring the significance of multi-point in-situ observations to better understand critical heliospheric phenomena. These include coronal mass ejections, magnetic flux ropes, heliospheric current sheets, kinetic waves and instabilities, suprathermal electrons and solar energetic particle events, as well as remote detection of solar radiation phenomena. Furthermore, the mission’s significance in advancing space weather prediction and space radiation exposure assessment models through the integration of L4 observations is discussed. This article is concluded with an emphasis on the potential of L4 observations to propel advancements in heliospheric science.

Operation procedures of civil defence authorities in time of war

The relevance of this study is determined by the current instability of the global political climate in the world and the outbreak of a number of military conflicts, which necessitates the study of the mechanisms of activity of structures that protect the interests of the population and the state. Thus, the purpose of the paper is to analyse the algorithm for the activities of civil defence authorities, particularly in wartime conditions. Among the methods used are the methods of logical analysis, deduction, synthesis, induction, functional analysis, analogy. This study provides a detailed analysis of the importance and key role played by civil protection agencies in addressing the challenges of protecting, ensuring security and developing society. The importance of their function lies in the effective implementation of strategies aimed at protecting the population and the state in times of threat and danger. The analysis in this paper takes into account the various components necessary for the successful management of various types of warfare. This includes the study of effective strategies for interaction and coordination between civil protection authorities and military command and control. Particular attention is paid to the key factors that determine the effectiveness of the organisation of interaction between military authorities and protection commissioners. Similarly, significant was the analysis of the demand for the resolution of qualitative foresight implementation tasks. Accordingly, an algorithm that will provide a more detailed and relevant examination of the wartime operational algorithm of the governing bodies has been developed. The practical value of the obtained results is that it will increase the appropriate level of combat alertness, the guarantor of the protection of the national interests of the state and its population, its territorial integrity and will generally raise the level of effectiveness of the relevant bodies considered

Objectives The purpose of this study is, on the one hand, to examine the experiences of individuals who are full-time employees and enrolled in the process of learning in counselor education, and on the other hand, to phenomenologically reveal the meaning behind their experiences.
 Methods Interviews were conducted on seven full-time employees who are in counseling graduate school for more than 3 semesters or within 1 year of graduation, and analyzed by Colaizzi's phenomenological research method. Participants consisted of those in their late 30s to early 50s who had more than 10 years of work experience and experienced vocational activities in different occupations from the counseling field. The data collection period was from September to December 2021, and after an in-depth interview of 90 to 120 minutes, additional interviews were conducted by phone or text message if necessary.
 Results As a result, 5 categories, 19 topic bundles, and 81 topics were derived. The five categories are as follows. ‘studying counseling to break away from current instability’, ‘making good changes during the counseling course of study’, ‘facing psychological difficulties arising from both occupation and academic affairs’, ‘maturing the mind through learning in counselor education’, and ‘running a life as an employee also doing in counseling job’. In conclusion, participants, with over 10 years of full-time work experience and a stable career will go to counseling, a new field, and the world of experience can be summarized as “growth through counseling studies upgrades professionalism in the current workplace and running a life as an employee also doing counseling job.”
 Conclusions The research results confirmed the experiences and meanings experienced in the course of learning in counselor education, and based on this, provided basic data for future related education and information provision.

Setups for eliminating static charge of the ATLAS18 strip sensors

Construction of the new all-silicon Inner Tracker (ITk), developed by the ATLAS collaboration to beable to track charged particles produced at the High-Luminosity LHC, started in 2020 and is expected tocontinue till 2028. The ITk detector will include 18,000 highly segmented and radiation hard n+-in-psilicon strip sensors (ATLAS18), which are being manufactured by Hamamatsu Photonics. Mechanical and electrical characteristics of produced sensors are measured upon their delivery at several institutes participating in a complex Quality Control (QC) program. The QC tests performed on each individual sensor check the overall integrity and quality of the sensor.During the QC testing of ATLAS18 strip sensors, an increased number of sensors thatfailed the electrical tests was observed. In particular, IV measurements indicated an early breakdown,while large areas containing several tens or hundreds of neighbouring strips with low interstrip isolationwere identified by the Full strip tests, and leakage current instabilities were measured in a long-term leakage current stability setup. Moreover, a high surface electrostatic charge reaching a level of several hundreds of volts per inch was measured on a large number of sensors and on the plastic sheets, whichmechanically protect these sensors in their paper envelopes. Accumulated data indicates a clearcorrelation between observed electrical failures and the sensor charge-up.To mitigate the above-described issues, the QC testing sites significantly modified the sensor handlingprocedures and introduced sensor recovery techniques based on irradiation of the sensor surface with UVlight or application of intensive flows of ionized gas. In this presentation, we will describe the setupsimplemented by the QC testing sites to treat silicon strip sensors affected by static charge andevaluate the effectiveness of these setups in terms of improvement of the sensor performance.

Long-term Effectiveness and Outcome-Determining Factors of Arthroscopic Bankart Repair for Recreational Sports Population: An Assessment of 100 Patients With a Mean Follow-up of 12.7 Years

Background: A limited number of studies have reported the long-term effectiveness of and associated factors for recurrence of anterior shoulder instability after arthroscopic Bankart repair (ABR). Purpose: To report the long-term clinical outcomes after ABR in a recreational sports population and identify the associated factors that influence the final instability status. Study Design: Case series; Level of evidence, 4. Methods: A retrospective study was performed in patients treated with ABR between 2007 and 2013 by a single surgeon. Patient data, magnetic resonance imaging measurements of bone loss and glenoid track, and intra- and perioperative factors were analyzed. After a minimum follow-up of 10 years, patient-reported outcomes including the Western Ontario Shoulder Instability Index score, the Rowe score, the visual analog scale for pain and function, the American Shoulder and Elbow Surgeons score, and sports activity were assessed. The current instability status was classified into 3 groups: stable, apprehensive, and redislocated. These groups were statistically compared with respect to outcomes and associated factors. Results: A total of 100 patients with a mean age of 22.4 ± 5.5 years and a mean follow-up of 12.7 ± 2.1 years were included. At the final follow-up, 38 patients (38%) showed recurrent symptoms: 19 patients (19%) with subjective apprehension and 19 patients (19%) with redislocation, including 10 patients (10%) with revision surgery. At the final follow-up, the redislocated group showed the lowest patient-reported outcomes and return to sports (both P < .001). The apprehensive group also showed a lower Western Ontario Shoulder Instability Index score (P = .011), Rowe score (P = .003), American Shoulder and Elbow Surgeons score (P = .027), and return to sports (P = .005) than the stable group. Participation in contact sports (P = .026), glenoid bone loss (P = .005), size of Hill-Sachs lesion (P = .009), and off-track lesions (P = .016) were all associated with recurrent symptoms, whereas age <20 years (P = .012), participation in contact sports (P = .003), and off-track lesions (P = .042) were associated with redislocation. Conclusion: After long-term follow-up in a recreational sports population, ABR demonstrated a 19% rate of subjective apprehension and 19% rate of redislocation, with a gradual decline in clinical outcomes and sports activity over time. Therefore, candidates for ABR should be selected based on consideration of risk factors such as off-track lesions, age <20 years, and participation in contact sports.
