Published: February 2025

Vestibular research is essential for understanding and treating disorders such as vertigo and Meniere’s disease. The vestibulo-ocular reflex (VOR) is a key method for assessing vestibular function and an essential tool for diagnosing vertigo. Traditionally, the VOR comprises angular VOR (aVOR) and translational VOR (tVOR), which originate from the vestibular semicircular canals (SCCs) and otolith organs, respectively. VOR consists of both fast-phase and slow-phase eye movements, which functionally interact to contribute to gaze control. However, to calculate the gain and phase parameters of the VOR, it is common practice to exclude fast-phase information superimposed on slow-phase eye movements. As a result, the information contained in the fast phase has not been fully utilized. OVAR is primarily used to evaluate otolith function, as there is no SCC input during its steady state. It is widely accepted that fast-phase nystagmus (FPN) during OVAR is generated by periodic otolith inputs via the central vestibular velocity storage mechanism (VSM). Surprisingly, we discovered in this study that SCC input can modify the generation of FPN in mouse OVAR test, as demonstrated by testingZpld1(Zona pellucida-like domain containing 1 protein) mutant mice with SCC deficits. This finding was further confirmed using both unilateral and bilateral semicircular canals dehiscence (SCD) surgical models. In addition to revealing the dependence of FPN on SCC input, we demonstrated that FPN can be used to evaluate vestibular function, particularly in conditions that are difficult to assess using slow-phase eye movements, such as unilateral vestibular lesions (UVL) and central modulation via Baclofen treatment.Significance statementAlthough the SCC input is absent during the steady state of OVAR test, we discovered that SCC input can modify the generation of fast-phase nystagmus (FPN) in mice. This was demonstrated usingZpld1mutant mice with SCC deficits and further confirmed through semicircular canal dehiscence (SCD) models. Additionally, we found that FPN is valuable for assessing vestibular function in conditions such as unilateral vestibular lesions (UVL) and in cases of central modulation by Baclofen, making it a promising diagnostic tool for vestibular clinics.

Authors: Swanepoel Azette , Van Heerden Susanna Maria 
Published: February 2025

First Year Students in Occupational Therapy enter Higher Education and take on different roles while engaging in occupations of academics, Instrumental Activities of Daily Living (IADL) and Social participation. Some of the roles are new and pose challenges to students which in turn influence their academic performance. Thus a qualitative study was conducted with eighteen first year occupational therapy students at the University of the Free State, with no prior higher education experience, were randomly selected to take part in the study. Data were collected from documentation and Nominal Group Technique discussions. Four roles were identified namely: role of a student, role of an independent young adult, role of a friend and role of a member of campus residence.

Published: February 2025

ABSTRACT
The shear-wave velocity (VS) structure plays an important role in characterizing site amplification. The Large-n Seismic Survey in Oklahoma (LASSO; 1820 stations) revealed large vertical ground-motion variability in a 25 km × 32 km area in northern Oklahoma. The LASSO array has a relatively simple and flat topography, typical in a sedimentary basin environment in the central United States. In this study, we use the dense array to investigate the velocity structure under the LASSO array and how vertical ground motions relate to the shallow-to-deep structures. We extract the fundamental-mode Rayleigh wave by cross-correlating one month of ambient noise (0.7–5 Hz). We use double-beamforming to measure the group and phase velocities and anisotropy. By jointly inverting the group and phase velocities, we obtain the VS structure. We observe correlations between VS at depths of 0.1–1.5 km and vertical ground motions using sites on the stiffer Permian formations. The shallow Quaternary alluvium and terrace deposits can amplify vertical ground motions by a factor of 2–4.5 between 2 and 25 Hz and attenuate signals above 25 Hz. We use 1D VS profiles to simulate the SV-wave transfer functions. An average VS of 250 m/s in the upper 20–40 m may cause the observed amplification between 2 and 40 Hz. VS estimated by topographic slopes cannot predict the relative amplification. Our results highlight the large variability of site-dependent ground motion in a small local region and the importance of characterizing shallow structures to estimate seismic hazards. Small thickness variations of the shallow formation can significantly change the resonance amplitude and frequency, which likely reduces the coherency of the Rayleigh waves extracted from ambient noise.
Mathematical Morphological Filtering with a Self-Adaptive Reconstruction Technique and Application to Local Seismic Data
Authors: Tibi Rigobert 
Published: February 2025

ABSTRACT
Recorded seismic data are generally contaminated by noise from different sources, which masks the signals of interest. In the seismology community, frequency filtering (FF) is the standard method for noise suppression. However, when the signal of interest and noise share the same frequency band, the latter cannot be filtered out without infringing on the former. We implemented a noise suppression approach based on the mathematical morphology theorem. The method involves compound operations of dilation and erosion using structuring elements of varying lengths and decomposes an input noisy waveform into several time functions with differing characteristics. The filtered waveform is constructed from the time functions using a self-adaptive reconstruction technique. Application to a data set of &gt;4700 local waveforms suggests that the implemented mathematical morphological filtering (MMF) approach is efficient for data with low signal-to-noise ratio (SNR) and significantly outperforms FF in that SNR range. For most of the dataset, FF, machine learning (ML) denoising, and continuous wavelet transform (CWT) thresholding result in higher SNR values compared with the MMF method. However, for ∼42% of the waveforms, MMF outperforms FF, and the SNR gain achieved with MMF is as large as ∼23 dB. Compared to ML denoising and CWT thresholding, this proportion drops to only ∼10%–14%. Our results suggests that in an operational setting, MMF cannot replace the other noise suppression methods; however, signal detection can be improved if MMF is used to supplement them in some scenarios. MMF could help detect signals in problematic low-SNR data, which are currently being missed particularly when using FF alone.

Selected Recommended Practices for Increasing the Efficiency and Accuracy of CO2 Sequestration Models

Published: February 2025

Summary
Computer simulation has become widely used to predict the life of CO2 plumes resulting from planned subsurface sequestration schemes. The process is very similar to what has been done in the oil and gas industry for decades; however, while reservoir simulations can be “history matched” to real-world performance, analog data are mostly missing to calibrate proposed CO2 project models. Therefore, it is critical to attempt to understand the impact of the various “default” input parameters that are often used in CO2 sequestration models. With this paper, we attempt to highlight potential enhancements in the modeling process that can lead to improved accuracy of predictions.
Many CO2 screening investigations use simple homogeneous block models in place of utilizing more complex realistic geologic models. Comparisons between homogeneous models of porosity and permeability with simple stochastically generated porosity and permeability (having the equivalent average values) could make significant differences. The use of black-oil models instead of compositional models will be investigated as a method to improve time efficiency, allowing the investigation of more “what-if” scenarios. Guidelines for simple calibration of a black-oil model to a compositional model are also presented.
The importance of residual phase trapping as a potential primary trapping mechanism in addition to structural and stratigraphic trapping will be investigated. While including parameters for residual trapping, too often, default values in simulation tools are used without recognizing the high variability of these parameters, especially considering the laboratory-based observations for some of them. Several scenarios are presented that highlight the importance of these uncertainties.
Endpoint values of relative permeability curves can have significant effects on plume geometry and are modeled in various scenarios. Critical gas saturation is often overlooked in the modeling process. This value is often defaulted to an unrealistically low value that can lead to “runaway” low saturation plumes when models are run for extended periods (as required by government regulations). Critical gas trapping at the edge of plumes can be an often overlooked additional trapping mechanism.

Published: February 2025

Summary
To accurately predict the sustained casing pressure resulting from tubing leakage in high-pressure and high-temperature (HPHT) gas wells during production operations, we developed a predictive model that incorporates the effects of tubing leakages, wellbore temperature changes, and multiannulus interactions. First, we determined the thermodynamic parameters of the annular liquid through a combination of experimental and computational methods. Next, we formulated a transient model to predict wellbore temperature and pressure. Then, we analyzed the coupling relationship between tubing leakages, wellbore temperature changes, and multiannulus interactions, and proposed an equation to calculate the sustained casing pressure. Finally, to illustrate the significance of coupled effects of multiple factors, we conducted a comparative case study using both the new model, which incorporates these effects, and the existing model, which considers only the tubing leakage. The characteristics of the sustained casing pressure were analyzed, and a sensitivity analysis was performed. The results show that, compared with measured data, the average error of the new model was 9.2%, which was much lower than the existing model’s 21.6%. The increase rate and maximum value of the annular pressure obtained by the new model were higher than those of the existing model. When the equivalent diameter of the leakage point was less than 0.65 mm, the coupled effects of multiple factors had a more pronounced impact on the sustained casing pressure. Optimizing the annular liquid density proved to be a more economical and effective method for mitigating the sustained casing pressure. This model offers valuable technological support for the prediction and analysis of the sustained casing pressure during production operations.
Comparison of the Effectiveness of CO2 and Hydrocarbon Gas for Shale Huff ’n’ Puff
Authors: Guo Yujia , Shi Yue , Mohanty Kishore 
Published: February 2025

Summary
The gas huff ’n’ puff (HnP) technique holds great potential for enhancing oil recovery from shale reservoirs following primary recovery. Both CO2 and hydrocarbon (HC) gases are commonly considered for HnP processes, each offering distinct advantages and disadvantages. In this study, we propose a novel experimental approach to systematically evaluate the enhanced oil recovery (EOR) potential of different injectants in shale cores and the potential carbon storage capacity for CO2 HnP. The HC gas mixture utilized consists of 72% methane (C1), 16% ethane (C2), and 12% propane (C3), closely mirroring the composition of available HC gas in oil fields. In each test, shale cores were first saturated with the dead oil, and then high-pressure methane diffusion was utilized to make in-situ live oil. Primary recovery was performed before HnP cycles. Next, six cycles of gas HnP were conducted with a huff pressure of 6,000 psi, a soaking time of 24 hours, and a puff pressure of 2,000 psi. The huff pressure was selected to be much higher than the calculated minimum miscibility pressure (MMP) to enable the development of miscibility of injected gases with the oil in the matrix. The EOR performance of each injectant was evaluated by analyzing oil recovery through nuclear magnetic resonance (NMR), core mass measurements, and effluent fluid collected at each step. The produced gas and liquid effluent were carefully collected and analyzed by gas chromatography (GC) analysis. The experimental results revealed that both CO2 and HC gas enhance oil recovery from the studied shale cores. After six cycles of HnP process, oil recoveries reached 84% for CO2 and 74% for HC gas. Oil recovery efficiency was about 58 STB/MMscf of gas injected. NMR results confirmed that most of the injected oil could be extracted after six cycles of gas injection. However, incremental oil recovery decreased significantly with each subsequent cycle for both gases. In addition, oil produced in later cycles generally had a higher fraction of heavy HC components, as evidenced by density measurements and GC analysis. CO2 can be stored in the pore space of the shale matrix, with up to 1.56 kg/ft³ of the shale bulk volume if the production is ceased in the final HnP cycle.
Self-Belief in Creative Fluency Mediates the Association between Life Satisfaction and Optimism Among Adults in Japan: Insights from an Online Survey and Case-Control Workshop
Authors: Kabir Russell Sarwar , Uehara Soshi , Walter Brett Raymond , Hihara Shogo 
Published: February 2025

Abstract

Background: In the context of Japan, beliefs about individual creativity are low. Studies rarely account for multiple factors of creativity or provide brief-session applications.
Methods: The present study (1) examines associations between originality and fluency as distinct sources of variation in self-beliefs of satisfaction with life (SWLS) and optimism (LOT-R) in an observational study design of national survey panel participants recruited during the COVID-19 pandemic (n=880; 401 females; Mage=38.12, SD=4.67), and (2) performs a quasi-experimental comparison of scores taken with emerging adults participating in a three-hour, intercultural creativity-based workshop featuring 15 U.S. and 25 undergraduate students from Japan.
Results: Results indicated correlational support for the two subscales of the Reisman Diagnostic Creativity Assessment (RDCA): originality (life satisfaction: r=.24; optimism: r=.29, ps <.001) and fluency (SWLS: r=.29; LOT-R: r=.31, ps <.001). Mediation analysis revealed unique support for the RDCA factor of fluency (β=0.15, p=.003) over originality (β=-0.03, p=.481) as a parallel mediator for the association between optimism and life satisfaction. Case-control comparison revealed that mean factor scores of survey participants for originality were comparable to creative self-assessments after the intercultural workshop (d=.110, p=.569), but fluency scores were numerically higher and statistically significant (d=-.444, p=.026), in favor of the workshop participants.
Conclusions: These findings suggest that the specific creative tendency to generate many ideas is relevant to well-being outcomes and might be shaped by educational settings for adults in Japan, offering implications for instructional designers targeting creative self-efficacy.

Published: February 2025

Abstract

Background
In 2020, the World Federation Dental highlighted the importance of oral health in "Vision 2030," noting the widespread impact of oral disorders, which affected 3.5 billion people in 2019. Despite their prevalence, these disorders are often overlooked in healthcare due to their non-life-threatening nature. This study evaluates the global, regional, and national burden of oral disorders from 1990 to 2021, providing insights for future oral health policies and addressing inequalities.
Methods
We analyzed data from the GBD 2021 database, examining incidence, prevalence, and DALYs of oral disorders from 1990 to 2021. We calculated age-standardized rates, Estimated Annual Percentage Change (EAPC), and percentage changes across super-regions, genders, SDI groupings, and 204 countries or territories. The Age-Period-Cohort model explored temporal burden differences, while the Geographically Weighted Regression model assessed the impact of social and commercial health determinants on ASIR.
Results
In 2021, global DALYs due to oral disorders reached 23.24 million, with 3.7 billion prevalent cases. The global ASDR and ASPR showed slight decreases, but ASIR increased. Sub-Saharan Africa experienced significant rises in DALYs, incidence, and prevalence. Edentulism accounted for 41.3% of DALYs worldwide. Middle SDI countries showed a rapid increase in disease burden, with children most affected. Social and commercial health determinants, notably smoking and sugar intake, considerably impacted LMICs more than HICs.
Conclusion
Oral disorders affect approximately 3.7 billion people globally, with LMICs experiencing doubled burdens. Vulnerable groups include children and the elderly, exacerbated by socio-economic disparities and commercial determinants. LMICs must enhance dental resources, integrate oral care into primary healthcare, and counteract commercial influences to ensure optimal oral health.

Abstract

This study explores the potential effects of climate change on runoff in the upper Birbir sub-basin of Western Ethiopia. Utilizing the Coordinated Regional Climate Downscaling Experiment (CORDEX)-Africa data from the Hadley Global Environment Model 2-Earth System (HadGEM2-ES), we made future projections under two Representative Concentration Pathway scenarios, RCP4.5 and RCP8.5, for the mid-term (2041–2070) and long-term (2071–2100). To evaluate data trends at a 5% significance level, we employed the Mann-Kendall (MK) trend test alongside Sen's estimators. For simulating future stream flow based on projected climate variables, we used the Hydrologiska Byråns Vattenbalansavdelning (HBV) model. The simulations of future runoff under climate change scenarios reveal that rainfall, with the exception of at the Yubdo station, tends to increase, while temperatures exhibit a warming trend. Runoff is expected to decrease in winter and spring but rise during the summer and autumn, largely following rainfall patterns. In the mid-term, we project an annual average runoff decrease of 2.05% and 1.35% under RCP4.5 and RCP8.5, respectively. Long-term runoff projections indicate a decline of about 0.03% under RCP4.5 and 2.0% under RCP8.5. The findings of this study are intended to assist decision-makers in mitigating the impacts of climate change and in the sustainable use of water resources for irrigation projects and other applications, while also considering the health of riverine ecosystems.
