The theory of event medicine: a literature review
Authors: Shelswell Robert 
Published: February 2025

Background: Event medicine is a field of medicine that encompasses the provision of healthcare to spectators/attendees at sports stadiums, music events, and festivals. This article explores existing theory to understand the evidence base currently afforded to operational practice. Aim: The study aim is to explore the current literature on event medicine to identify collective themes and areas for future research, prompt clinician reflective practice, and inform future standards of professional practice. Methods: A six-stage thematic-analysis-based literature review was conducted. The electronic databases of Google Scholar, Medline and PubMed were searched between January and April 2024. The search terms used were ‘event medicine’, ‘mass gathering medicine’, stadium medicine’, and crowd medicine’. Articles prior to January 2004 were excluded. The search included English language full-text articles. Findings: A total of 32 articles were selected. They originated from Europe, Northern America, Southern Africa, and Asia, across a variety of sporting, outdoor festival, and music events. From their analysis, five main themes were identified: patient presentations; medical resource skill mix; predictive modelling; transfer to hospital rates; and acute cardiac events. Conclusion: Event medicine operational practice is under-researched, and essentially affords a large theory-practice gap in event medical service planning, provision, and application. Event-medicine clinicians should aim to deliver prehospital medical care that reflects the complexity of the five identified themes, as well as critically analyse existing event medical data, challenge their conceptual roles, and seek to develop future improved core standards of event medicine with a view to developing safer models of care for event spectators/attendees.

Published: February 2025

Background
After two decades of mass drug administration (MDA) for schistosomiasis in Burkina Faso, an impact assessment was conducted in 16 health districts (HDs) between February 2023 to March 2024 to determine the epidemiological situation of schistosomiasis in school-aged children and facilitate the decision for sub-district level treatment decision.

Methodology/Principal findings
A cross-sectional cluster survey was conducted with randomly selected children aged 5–14 years. Haemastix reagent strips were used to detect microhaematuria in urine, and urine filtration was used to detect and quantify Schistosoma haematobium eggs in children with microhaematuria. The Kato-Katz was used to detect and quantify S. mansoni eggs in fecal samples. The prevalence of infection and the prevalence of heavy-intensity (HI) infections were calculated. The overall prevalence of schistosomiasis was 2.4% (range: 0–11.1%) in 16 HDs, with the overall prevalence of HI infection of 0.9% (range: 0–4.2%). Four HDs (Tenkodogo, Batié, Sig-Nonghin, and Karangasso-Vigué) had a prevalence of HI infection from 1.3% to 4.2%. Forty-seven health areas still had an overall prevalence of 1.4–62.5%, with seven health areas in five HDs >10%, and 29 health areas had a prevalence of HI infection from 1.4% to 22.9%. Boys had a higher prevalence of HI infections than girls. The prevalence of microhaematuria at 5.8% was significantly higher than that of S. haematobium infection by urine filtration at 2.3%, and Haemastix results were significantly associated with the intensity of infection.

Conclusions/Significance
The results showed that progress has been made in eliminating schistosomiasis as a public health problem in the 16 HDs in Burkina Faso after two decades of mass treatment. However, hotspots of infections remain, with 29 health areas having a prevalence of HI infection above the 1% threshold. The results provide evidence for planning targeted sub-district-level treatment.
Training physicians to work in a second language
Authors: Szymańska Oliwia 
Published: February 2025

This study highlights the importance of targeting practices that facilitate physician-patient communication in language courses for health professionals. The aim of this study is twofold. Firstly, it examines if and how physicians with a second language deploy metaphors to facilitate understanding. Secondly, it investigates how this practice can be enhanced through communicative training. The study comprises two separate parts, each with a different approach, method, and participants. Study 1 investigates the use of metaphors in authentic situations from outpatient clinics, where physicians consulted patients in L2 Norwegian. The data consists of transcripts of video recordings and an interview with one of the physicians. Study 2 examines the outcomes of an intervention during an intensive language course before the physicians’ arrival in Norway. The data in this study include oral and written production, as well as an interview with one of the participants. Study 1 revealed contexts in which migrant physicians deploy metaphors to facilitate their communication in L2 and types of the expressions they use. Study 2 showed that stimulating metaphor awareness might be beneficial for metaphor use in communication and comprehension in visual representation, which in turn can support L2 communication in the physicians’ everyday practices.
Prediction method of S-wave velocities in tight sandstone reservoirs – a case study of CO2 geological storage area in Ordos Basin
Authors: Li Lin , Wang Haofan , Ma Jinfeng 
Published: February 2025

Abstract
S-wave velocity, among the critical parameters essential for developing 3D/4D seismic forward models, is prominent. Variations in both P- and S-wave velocities result from changes in the formation pressure and fluid saturation inside reservoirs during CO2 geological storage operations. This study, understanding the significant variety and uneven stress distributions of tight sandstone reservoirs in the Ordos Basin, begins with developing a predictive model for S-wave velocities. The model integrates the Digby and DEM models and takes into account the changes in the formation pressure and alterations in pore shapes. Data from petrophysical experiments are used to validate this model. By comparing the shear wave velocity prediction results under four pore shapes, spherical, needle-shaped, disc-shaped, and coin-shaped gaps, the dominant pore shape of this sedimentary facies belt was selected, and the pore shape of the target layer was identified as needle-shaped pores. The shear wave velocity prediction model for this area was then optimized. Moreover, by analyzing actual well logging data, the methodology is validated and it shows high accuracy when using the dominant pore shapes to predict the S-wave velocity. This study emphasizes how important it is to take geological factors into account when developing 3D/4D seismic petrophysical predication models of S-wave velocities specifically designed for tight sandstone reservoirs.
Effect of pore throats on the reservoir quality of tight sandstone: A case study of the Yanchang Formation in the Zhidan area, Ordos Basin

Published: February 2025

Abstract
Due to the tight sandstone widespread development of nanoscale pore-throat systems, the microscopic pore-throat characteristics of tight reservoirs are the focus of research. Taking the main tight oil production province of the Ordos Basin in China as a case study, nuclear magnetic resonance (NMR), pressure-controlled mercury injection (PMI), scanning electron microscopy, and micro-computed tomography (μCT) are used to analyze the characteristics of four types of tight sandstones with different pore throats. Furthermore, the effects of pore throats on movable fluid, connectivity, and reservoir physical properties are analyzed. The results show that the pore throats of the four types of tight sandstones are obviously different, but they are all dominated by nanoscale pore-throat systems. From types I to IV, the pore types of the tight sandstone change from residual intergranular pores to the coexistence of feldspar dissolved pores and residual intergranular pores and then to the coexistence of residual intergranular pores and intergranular micropores. The T
2 NMR spectrum changes from a double peak to a single peak, the pore-throat connectivity revealed by μCT decreases from 83.8% for type I to 13.1% for type IV, the pore-throat volume ratio revealed by PMI decreases from 2.09 to 0.43, and the NMR movable fluid saturation decreases from 38.91 to 12.39%. Tight sandstone with larger pores and a uniform distribution has high movable fluid saturation and good pore-throat connectivity. Although the tight sandstone with dissolved pores and intergranular pores may have a medium porosity, the pore–throat connectivity deteriorates compared with high porosity sandstone. Large pore throats, which account for less than 15% of all pore throats, contribute more than 90% of the permeability, while pore throats less than 0.8 μm in diameter are major contributors to the reservoir space, and both the porosity and permeability decrease as the pore-throat diameter decreases.

Authors: Panagiotou Dimitrios 
Published: February 2025

Abstract
The present study investigates the linkages among the futures prices of feeder cattle, live cattle and lean hogs in the US. This has been pursued using a flexible methodology that allows modelling price relationships at different parts of their joint distribution. Data are daily closing prices for the period between 1/1/2015 and 12/31/2023. According to the empirical results: i) livestock commodities boom together and crash (with one exception) together, ii) extreme price decreases are transmitted with higher intensity compared to extreme price increases, iii) transmission asymmetries in prices, between livestock commodities, can occur at the tails as well as at the median of the joint distributions. Lastly, opportunities for speculators to profit from the spread between the commodities of feeder cattle and live cattle can be present.

Abstract
In this paper, we explore the interconnection of natural processes and current technologies to satisfy the emerging requirements of next-generation Internet of Things (IoT) ecosystems. Motivated by biological networks, we propose a novel routing and optical communication approach that leverages nature’s ability for self-organization, flexibility and resilience. This paper presents a model for bio-inspired routing protocols to be used in Internet of Things networks in order to improve scalability, reduce latency and maximize data transmission efficiency. Moreover, we investigate the potential of optical communication technologies, which are fast, low-latency and energy-efficient, to support the immense data transmission requirements of Internet of Things systems. The research finds key barriers and opportunities for integrating nature-based approaches.

Published: February 2025

Abstract
Ceramics are one of the key materials of today’s industry. The manufacturing technique used for preparing the ceramics greatly affects the material’s structural and electrical properties. Therefore, the elements and their distribution in the material as well as understanding their relation with the manufacturing process are the key factors for managing the expected outcome. In this study, NaNbO3 ceramics and the effect of CuO-doping in solid state calcination process was investigated. For this purpose pure, 0.5 mol.% and 1.0 mol.% CuO-doped sample discs were prepared. Crystallite size, strain, atomic structure, lattice parameters and atomic occupancies of the material were calculated by using X-ray diffraction patterns combined with Rietveld analysis. Additionally, the samples were investigated with the scanning electron microscopy technique to observe the effect of CuO doping. For electrical characterization, dielectric constant and tangent loss measurements were carried out on samples. As a result, it was concluded that CuO doping affected the crystal structure of the NaNbO3 which triggered the changes in its electrical behavior. The observed effects were more pronounced at 1.0 mol.% CuO content.
Evaluating the Impact of Spectrum-Matched Time Histories on Biased FRS Estimates: Part 1-Sensitivity Analysis Using Machine Learning
Authors: Li Bo 
Published: February 2025

ABSTRACT
In the wake of the Fukushima nuclear disaster, assessing the seismic safety of nuclear facilities, especially the secondary system, has become crucial. Floor response spectra (FRS) are keys to this assessment, typically generated through time history analyses. However, prior research shows that different time histories matching the same target spectrum can produce highly variable FRS estimates. This study examines the impact of spectrum-matched time histories on biased FRS estimates using machine learning methods. We generated 1750 spectrum-matched time histories based on five distinct target response spectra and applied them to eight typical steel moment-resisting frame buildings to compute their FRS. Machine learning techniques were then used to analyze the sensitivity of FRS estimates to modifications in ground-motion parameters due to spectral matching. The results indicate that changes in spectral accelerations are the primary factor influencing biased FRS estimates, followed by the damping scaling factor index for damping ratios of 7%, 2%, 10%, and 1%. These findings will aid in generating more accurate spectrum-matched time histories, reducing the risk of biased FRS estimates and improving seismic safety assessments for nuclear facilities.

ABSTRACT
The Guangdong–Hong Kong–Macao Greater Bay area, a highly populated region, plays a vital role in the economic development of East Asia. Its construction and development rely on accurately characterizing near-surface loose sediment layers. However, traditional drilling and active source methods are often impractical for large-scale exploration in densely populated areas due to their high costs and destructive nature. To overcome this shortage, a dense array comprising 6214 stations was deployed and the noise horizontal-to-vertical spectral ratio method was employed to determine the fundamental frequency (f0) and peak amplitude. The Quaternary sediment thickness was further estimated based on their empirical relationships with f0. More importantly, several buried paleochannels were identified, manifesting deep valleys on the vertical section and curved stripes on the horizontal section. Combining regional drilling data and sites of geological hazards in the past, we conclude that the paleochannels are zones of high seismic and geological hazard. This study provides a scientific basis for urban construction and disaster prevention.

Condensate dropout in the reservoir, below the saturation pressure, leads to a change in the composition of hydrocarbon gas and liquid at reservoir conditions, blocking part of the pore space, resulting in reduced well productivity. It also causes the composition of the fluid carried to the surface to contain a smaller amount of valuable intermediate hydrocarbon components such as C5+. The condensate dropped-out in the reservoir remains immobile until its saturation exceeds the critical saturation, or it is re-evaporated by miscible injection at pressure. The volume of the condensate bank in the reservoir and the resulting residual condensate reserves can reach tens of millions of m3 and, as a rule, consist of light and valuable hydrocarbon fractions. This publication investigates, using a compositional hydrodynamic simulator, the possibility of re-vaporizing a given volume of condensate and producing it by injecting a fluid that, at a given pressure and temperature, will mix with the condensate in the reservoir and form a single phase. A low-permeability gas condensate reservoir (0.001–0.1 mD), developed using a horizontal well with multi-stage hydraulic fracturing, is considered as a synthetic model. The results of the simulation showed a significant change in the composition of reservoir fluids with a corresponding decrease in reservoir pressure. The composition of the dropped-out condensate was determined, and a method for its mobilization by sequential injection of a mixing agent and production (huff-and-puff) was tested for different injection fluids. The methodology for selecting an injection agent based on the equation of state (EOS) in a PVT package for mixing displacement is considered and described. This type of numerical sensitivity provides a better understanding of the phase behavior of gas condensate, not only along the wellbore or fractures but also deep into the reservoir. It allows engineers to better optimize the development process and achieve significantly higher gas and condensate recovery rates by injecting a miscible fluid that is properly selected for a particular fluid system.
