Published: February 2025

Solitary fibrous tumor (SFT) is a rare neoplasm, belongs to spindle cell tumors of mesenchymal origin, which usually arise from serous membranes, but can also be detected in tissues of other organs. SFTs are predominantly benign tumors, however, the frequency of malignancy, according to various authors, can reach up to 15—20%. The share of SFTs of the head and neck organs is 25% of all localizations. In the larynx, SFT is quite rare. SFT is characterized by the difficulty of preoperative and differential diagnostics, requiring immunohistochemical examination. In immunohistochemical examination, CD34 and Vimentin are positive in most cases, CD99 in 50%; Cytokeratin, bcl 2, S100, SMA, CEA, MSLN, Desmin are negative in most cases. The gold standard is the determination of STAT6 expression. The basic method of treatment of SFT patients is surgical therapy.

Objective. To determine clinical and morphological predictors influencing the achievement of pCR in patients with breast cancer (BC) after neoadjuvant therapy (NAT), and to evaluate oncological outcomes in the group with and without NAT. Material and methods. A single-center retrospective non-randomized study was conducted, for which 984 patients with stage I–II breast cancer treated at the P.A. Herzen Moscow Oncology Research Institute from 2014 to 2022 were examined, in whom the surgical stage included subcutaneous/skin-sparing mastectomies with simultaneous reconstruction. The study participants were divided into 2 groups: Group 1 (n=276) — patients who received NAT courses at stage 1, Group 2 (n=708) — individuals who underwent surgical treatment at stage 1. Depending on the biological type, NAT included the following treatment regimens and number of courses: 4AC+4T for the luminal HER2-negative type, 6TCN or 6TCN+pertuzumab for the HER2-positive type, 4AC+4 paclitaxel/carboplatin for the triple-negative type. Subcutaneous mastectomy with reconstruction was performed in 617 (60.5%) patients, skin-sparing mastectomy — in 403 (39.5%) patients. Results. When analyzing the treatment results of 276 patients in group 1, a complete pathomorphological response (pCR) according to the morphological examination of the surgical material was achieved in 141 (49%) cases. The relative risk (RR) of developing local recurrence of breast cancer was 0.528 (CI 0.237—1.177) in group 1 and 1.962 (CI 0.880—4.375) in group 2. Metastases in the 1st group were detected in 5.4% of patients (pCR — 2.1%, non pCR — 8.8%), 5-year overall survival was 98.6%, event-free survival reached 92.1%, in the 2nd group metastases were detected in 5.4% of patients, overall survival for 5 years was 98.2%, and event-free survival was recorded at 89.8%. Conclusion. Achieving a complete pathological response is a marker of a decrease in the frequency of metastases and relapse. Achieving pCR reduces the risk of an adverse event, which follows from the analysis of event-free survival, which was 94.3% versus 87.8% among patients with pCR and non pCR, respectively.

Published: February 2025

Introduction and aim: Research indicates that premature infants are at risk of neurological abnormalities and developmental and functional delays during infancy and early childhood. Annually, in South Africa, approximately 15% of infants are born prematurely, the majority being from low socio-economic homes. Basic needs and survival of the infant take priority over developmental progress of infants. Since developmental progress is dependent on sensory integration, the aim of this study was to determine the occurrence of developmental and sensory integration difficulties in premature infants in South Africa.Methods: A descriptive, observational study was conducted. Relevant information on medical history and environmental factors were obtained through parent questionnaires. Three standardised assessments, the Bayley III Scales of Infant and Toddler Development, the Test of Sensory Function in Infants and the Infant/Toddler Sensory Profile, were used.Results: Infants presented with low average to average performance in all developmental subtests. The majority (67.7%) of infants presented with typical sensory seeking behaviour. Sensory processing difficulties were identified in terms of high neurological thresholds resulting in low registration behaviour as well as low neurological thresholds, resulting in sensory sensitivity and sensory avoiding behaviour. This influenced their adaptive motor functions and normal development.Conclusion: Premature infants participating in this research presented with challenges regarding developmental and sensory integration.Key words: sensory integration difficulties; development; premature infants; South Africa.

Authors: Strauss Monique , Van Heerden Susanna Maria , Joubert Gina
Published: February 2025

The mental health care user (MHCU) with psychosis has restrictions in occupational performance components and occupational performance areas, causing impaired activity participation, compromising the achievement of Occupational Therapy (OT) goals with this population.Â  The effect of slow versus fast tempo music during OT treatment of the MHCU with psychosis was investigated by means of a quantitative, experimental study. One hundred and sixty MHCUs with either inhibited or agitated symptoms of psychosis were included. The activity participation of the MHCUs, in terms of attention, following of instructions, directedness towards activity and willingness to participate were evaluated by three assessors through a pre- and post-test. The study indicated that music tempo, together with activity, has the ability to improve attention, following of instructions and directedness towards activity in the inhibited MHCU and attention and following of instructions in the agitated MHCU.Â  Occupational therapy with music elements might be useful when working with the MHCU with psychosis.KEY WORDSMental Health care user (MHCU), Psychosis, Occupational Therapy, music tempo, occupational performance component (OPC), occupational performance area (OPA)

The FUTURE project aims to enhance seismic surveying in South African mining by integrating advanced acquisition technologies. In this paper, we detail surface and underground seismic surveys at the South Deep gold mine as part of the project. Surface seismic acquisition used co-located broadband micro-electromechanical sensors, one and three component recorders connected to geophones, distributed acoustic sensing using a straight fibre optic cable, along with a 6 ton broadband seismic vibrator operating with 4-180 Hz linear sweeps. In addition, underground surveys employed a combination of straight, and helically wound fibre optic cables, cabled-based and nodal sensors, along with a 500 kg drophammer mounted on a skid steer bobcat. The surface and underground seismic arrays were time synchronised using a GPS-time transmitter to allow for accurate seismic data recording in a GPS-denied environment. Results show the efficacy of these techniques in acquiring high-resolution seismic data, revealing detailed subsurface geological structures and mineralisation down to 3500 m below ground surface. Surface data revealed clear seismic reflections corresponding to the Black Reef and Ventersdorp Contact Reef. An underground P-wave velocity model exhibits low velocity anomalies that are associated with fracturing, while a P-wave reflection stack section shows significant reflections and a degree of faulting below the tunnel floor that was not observed on the surface reflection seismic data. We highlight the potential of these technologies to enhance safety, efficiency, and sustainability in mining. This study sets a benchmark for future reflection seismic surveys, paving the way for safer, more efficient, deep mineral exploration and extraction practices.

Understanding the distribution patterns of species is crucial for developing effective conservation strategies, particularly in regions with high biodiversity and endemism like Ecuador. Amphibians, especially poison dart frogs (Dendrobatidae), serve as important bioindicators of environmental health, yet they face significant threats from habitat loss, climate change, and other anthropogenic factors. This study examines the distribution patterns of poison dart frog species across various provinces and protected areas in Ecuador, utilizing an updated database containing 48 species, 32 of which are endemic to the country. Cluster Analysis and Principal Component Analysis (PCA) were applied to compare provinces and protected areas based on species richness, effectively identifying regions with higher and lower poison dart frog species presence. Additionally, ecological factors and the influence of protected areas on the distribution of these frogs are discussed. The findings reveal regions of high species richness, underscore the potential effects of environmental changes on poison dart frog communities, and highlight the crucial role of protected areas in safeguarding biodiversity. This study underscores the importance of integrating these analyses into conservation planning and decision-making processes, aiming to protect poison dart frogs and their habitats. By addressing these challenges, this research contributes complementary perspectives into preserving Ecuador’s unique amphibian diversity.

Published: February 2025

Ignorance of the rational use of insecticides leads farmers in developing countries such as Ecuador to exceed the limit of permitted applications. In addition, little is known about the effect of insecticides on entomofauna of Lupinus mutabilis (lupine). This study aims to analyze the effect of insecticides on pests and beneficial insects, with special emphasis on pollinators, without neglecting the effect on crop yield. The entomofauna associated with Andean Lupin was used as a reference. Seventy-nine agricultural fields were evaluated in Cotopaxi-Ecuador, with the treatments with chemicals, without chemicals, and without any control. Once the experiment was presented to the participating group, the farmers chose the management treatment for their fields with recommendations from the researchers. For insect monitoring, yellow sticky and plate traps were used to obtain variables of insect abundance and diversity. The use and application of pesticides was recorded using surveys developed with Survey 123. The results showed that the application of insecticides was not always effective in controlling the pests studied. In addition, the treatments evaluated had different effects according to the type of insect pollinator analyzed. On the other hand, the study also showed that certain pests, especially borers, could induce a positive response (70 % more flowers) that can actually benefit the final yield. These results suggest that pest controls for this crop should be more targeted and carried out before flowering to avoid causing damage to pollinators and borers, as well as natural enemies of pests.

Published: February 2025

Although the vertical structure of rain is relevant in aspects such as climate models (CM) and quantitative precipitation estimation (QPE), data about it is limited in the Andes. Within these aspects, extreme rainfall events are important due to their potential social impacts. Therefore, this study aims to characterize the vertical structure of rain and extreme events in the Tropical Andes using a Vertically Pointing Micro Rain Radar. For this, (i) the diurnal rainfall cycle was determined; (ii) the bright band was characterized; (iii) common characteristics of the vertical rain profile during extreme events, along with the average vertical reflectivity profiles of different development stages of a characteristic extreme event were studied. The study was performed using five years of data from a vertically pointing rain radar installed in Cuenca, Ecuador. The main results indicate that (i) rain events with high intensities are concentrated between 12:30 – 20:00 h (Local Time), during which 77 % of the total rainfall occurs; (ii) the bright band has a thickness between 200 and 400 m, and its top (melting layer) is located between 4500 and 4900 m above sea level; (iii) rainfall shows a high variability in the water column: during the convective stage reflectivity values can increase up to 94 % from the fusion layer to the ground. The results show the complexity of rainfall events in the Andean region and the need to consider these aspects into CM and QPE to improve their accuracy.

The growth system of microalgae photobioreactors (PBRs) has drawn a lot of interest as a viable and sustainable method for generating quality biomass for value-added products and biofuels. The objective of this research work is to cultivate micro-algae species Chlorella vulgaris in a photobioreactor that was designed, fabricated, and powered by solar energy system. Three experimental conditions were compared with 1:4 ratios of microalgae culture (40L) and fresh water (10L) having 100mL of media (nutrients) used in each experiment with control sample (ambient air aeration) experiment # 1, injecting 200 g of CO2 for 15 sec (experiment # 2), and 300g of CO2 for 25 sec (experiment # 3) on alternate days during the cultivation period. All experiments showed the reduction of nutrients concentration (orthophosphate and nitrate) and enhancement of biomass productivity with respect to 10 days of cultivation period. Experiments 1, 2 and 3 showed removal of orthophosphate as 50 %, 41.74 % and 60.78 % respectively, whereas nitrate removal was 22 %, 48 % and 58 %. Biomass productivity from experiments 1, 2 and 3 after 10 days of cultivation period were 196.63 mg/L, 203.43 mg/L, 318.76 mg/L respectively. Statistical analysis revealed that supplying CO2 from external source in experiment # 2 and experiment # 3 have same pattern of statistical significance with co-relationship between two groups of means with p-value of 6.306 × . The maximum microalgal biomass was recovered from experiment # 3, with 7.98 % by weight protein content yield and lipid content yield 37.4 % by weight (1.87/ 5 g of dried biomass). Kinetic study showed volumetric mass transfer capacities of  and  were found to be 1.763× /s and 1.676× /s, with better result of  gas transfer capacity of the system. In the extracted lipids favorable qualities of fatty acids for the production of microalgae biodiesel were found such as myristic (C14:0), palmitic (C16:0), palmitoleic (C16:1), oleic (C18:1), linoleic (C18:1), and linolenic acids (C18:3). The use of urban micro-algae photobioreactors is an environmentally sustainable strategy that can contribute significantly to the bio-based economy and reduce the negative effects of traditional fossil fuel usage on the environment.

Published: February 2025

To increase the nutritive value of Lupinus mutabilis Sweet (chocho) foliage meal by solid-state fermentation with Aspergillus niger J1 and Trichoderma viride M5-2 strains, two laboratory experiments were carried out. A completely randomized design with 2×8 factorial arrangement and three replicates was used. The two strains of lignocellulolytic fungi and the fermentation times (0, 24, 48, 72, 96, 120, 144 and 168 h) were selected as factors. Samples were taken every 24 h for enzymatic analyses (exo β1-4 glucanase) and chemical composition (neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose and lignin). Substrate pH and moisture, as well as phenolic and flavonoid content composition were measured. Variations in the physicochemical properties of the flour studied were observed, with decreases in NDF, flavonoids and phenolic content by both strains, reaching a maximum of 12, 75 and 84 % respectively in a maximum time of 168 hours in the fermentation with A. niger J1 (P<0.01). In enzyme kinetics, interaction was observed in all factors (P<0.01). High values of exo β 1-4 glucanase enzymes were recorded in L. mutabilis Sweet with strain T. viride M5-2 at 96 h and sustained this activity over time for A. niger J1 with 0.189 UPF/mL. T. viride M5-2 and A. niger J1 strains improve the nutritive value of legume meal.

Authors: Afifi Tracie O. , Osorio Ana , Fortier Janique , Stewart-Tufescu Ashley , Taillieu Tamara L. , McCarthy Julie-Anne
Published: February 2025

Objectives

Although past studies have identified sex differences in child maltreatment experiences and poor mental and physical health‒related outcomes, more research is needed to understand child maltreatment among sexual minorities (i.e., those who identify as other than heterosexual) and how child maltreatment and sexual identity are related to depression, anxiety, and at-risk alcohol and cannabis use among emerging adults.

Methods

Data were drawn from the longitudinal Well-Being and Experiences (WE) Study collected from 2017 (14 to 17 years) to 2022 (18 to 23 years) from Manitoba, Canada (n = 584). Descriptive statistics and logistic regression models were computed.

Results

Compared to heterosexual or straight sexual identity: homosexual, gay or lesbian; bisexual; and different or other identity were associated with an increased likelihood of experiencing child maltreatment, with the most robust relationships for bisexual identity and all child maltreatment outcomes. Indicating “I don’t know” for sexual identity compared to heterosexual identity was associated with 7.45 increased odds of exposure to intimate partner violence in adjusted models. Bisexual identity compared to heterosexual identity had the most robust association, with increased odds of depression, anxiety, at-risk alcohol use, and at-risk cannabis use. Findings provide some evidence to suggest that trends may be worse for some mental health and substance use outcomes among sexual minorities who also experience child maltreatment.

Conclusion

Preventing child maltreatment among all children, including youth identifying as other than heterosexual, is a public health priority. Such efforts will work towards optimizing mental health and reducing substance use in early adulthood.
Development of a Program Evaluation Framework for Improving the Quality of Undergraduate Medical Education
Authors: Kang Yulim , Kim Hae Won , Choi Jun Yong
Published: February 2025

The development and implementation of a systematic program evaluation framework is critical for improving the quality of the undergraduate medical education. At Yonsei University College of Medicine, we established the following five evaluation domains that encompass various aspects of educational experiences: (1) preclinical curriculum; (2) clinical curriculum; (3) educational environment, resources, and systems; (4) performance of students and graduates and program outcomes; and (5) implementation and outcomes of the curriculum. Specific evaluation indicators were designed within these domains and validated through the Delphi technique, which integrated expert opinions. In total, 98 indicators were identified across five domains. These indicators will function as a comprehensive tool for assessing medical education programs. The proposed evaluation framework addresses both shortand long-term educational changes, facilitating systematic monitoring, continuous quality improvement of curricula, and better outcomes for students. As this framework is grounded in the unique context of the institution, it is appropriate for a comprehensive evaluation of interactions at various educational stages. Furthermore, it may serve as a strategic foundation for identifying areas that require improvement, ensuring that the curriculum aligns with current medical education standards and practices. The framework’s structured approach and continuing evaluation processes may make it possible to obtain essential data for ongoing development, potentially contributing to a robust system for quality improvement in medical education. The findings of this study are expected to serve as a valuable reference for developing similar evaluation frameworks in other medical schools.

Published: February 2025

As artificial intelligence (AI) technologies advance and become increasingly integrated into medicine and healthcare services, there is a growing consensus that it is necessary to prepare medical students to understand and utilize AI in medical education. Research and discussions are ongoing regarding the AI competencies that healthcare professionals should have. There are diverse opinions on how to integrate the necessary AI competencies for medical graduates into existing curricula. However, wide agreement exists regarding the importance of providing sufficient and appropriate education on the ethical aspects of using AI in clinical practice and research. In this paper, the authors aim to introduce practical educational principles, strategies, and methods for educators interested in teaching AI ethics in medicine. To achieve this, the paper (1) introduces the AI competencies and medical ethics competencies that medical school graduates should possess; (2) explains the necessity of fostering AI ethics competencies in medical education; (3) discusses the principles of developing AI ethics education and considerations for implementing such curricula; and (4) presents educational modules that can be utilized to cultivate AI ethics competencies in medical students and young physicians. The authors of the paper hope that the case-based module on medical AI ethics we have developed may contribute to prepare medical graduates who are familiar with the principles and guidelines of medical AI ethics, enabling them to make the best ethical choices in any given environment.

Published: February 2025

In this paper, we continue our study of the damped Rayleigh beam system. The purpose of this work is to add two additional force controls in moment and rotation and see if this remains exponentially stable. Thus we obtain a four-control system. Using the Riesz basis approach, we prove the stability of nonhomogeneous Rayleigh beam via an indefinite damping and the boundary control feedbacks in position, velocity, moment and rotation. We transform the system to an evolution problem and prove that the linear operator of the Cauchy problem generates a semigroup of contractions. Subsequently, we show how the damping term can affect the decay rate asymptotically.

Authors: Shamionov R.M. , Sharov A.A.
Published: February 2025

The purpose of the study is to identify the role of adaptive readiness and subjective assessment of the situation in the academic adaptation of students. The results were obtained from a sample of 385 respondents studying at higher educational institutions in Moscow, Volgograd, as well as Saratov and the region. The following tools were used: the "Scale of diagnostics of adaptive readiness of personality" (M.V. Grigorieva), the methodology of diagnosis of academic adaptation (R.M. Shamionov et al.), the author's scales of significance and stress of situations in the educational environment. It is shown that the predictors of academic adaptation of students are interactions with the administration and classmates, the importance of lectures. It is revealed that the psychological component of adaptive readiness is a predictor of academic adaptation. The travel analysis confirmed the hypothesis of the leading role of relations with the administration and classmates, lecture classes in their academic adaptation. The psychological and socio-psychological components of adaptive readiness also play an important role in the academic adaptation of students. It has been established that the components of adaptive readiness are direct predictors of academic adaptation. In addition, they are mediators of a direct link between the attitude to the educational environment and academic adaptation. It is concluded that mediation of adaptive readiness in the presented model can be recommended for the development of academic adaptation programs.

Introduction
The development of hyperammonemia and subsequent hepatic encephalopathy (HE) after the application of artificial portosystemic shunts (APS) in children with portal hypertension (PH) continues to be an urgent problem in modern pediatric surgery. To date, there have been no data on the study of the prevalence of hyperammonemia after various vascular bypass operations (for PG) in large groups of patients. Solving this problem may make it possible to make an adequate choice of treatment method for children with PH, taking into account the risk of developing НE in the future.
Material and methods
This work analyzed the results of 480 studies of ammonia levels in the blood of 223 children, of which 197 had liver disease (the majority had undergone vascular bypass surgery).
Results
According to the analysis, in unoperated patients with PG the risk of hyperammonemia is small, but it increases after the use of certain vascular bypass operations. To the least extent, this applies to physiological mesoprotal shunt (MPS) and selective distal splenorenal shunt (DSRS), and to the greatest extent to total PSS: splenorenal shunts (SRS) (side-to-side splenorenal shunt, splenosuprarenal shunts) and mesocaval shunt (MCS).
Conclusion
Our data confirm the advantage of MPS and DSRS compared with SRS and MCS in terms of the low risk of developing hyperammonemia in childhood. At the same time, the study confirms the effectiveness of SRS reconstruction in DSRS in terms of reducing blood ammonia levels.

Published: February 2025

We study the applicability and limitations of the single-station P-wave seismogram method for estimating VS30 by analyzing data from two accelerometer arrays in Greece. Although the method (and its variants) is usually applied at regional and local networks using small earthquake data (M 2–5), we employ a rather small number of stations (25) from the two arrays to validate the method against detailed geophysical models available for these test sites. We also examine the method applicability to downhole accelerometers, not considered in similar studies. The results show a rather systematic overestimation of the time-averaged (to depth z) shear-wave velocity, VSZ, for most stations. We employ a Monte Carlo approach with synthetic data to quantify the effect of hypocentral errors and explore possible correlations between the ray parameter, p, and VSZ. We find a clear correlation between the epicentral error and extremely large VSZ-values (even >5 km/s). Removing records with low ray parameters (p <0.1 s/km) significantly improves the result stability. We also identify a correlation between the earthquake local magnitude ML and the estimated VSZ-values, in agreement with theoretical considerations, and propose a correction for this effect. Using reference geophysical models for the two arrays, we confirm that the method exploration depth z increases with the pulse duration of the source time function (τp), though with a larger average τp=0.15  s value for M∼3.0 events than previously suggested. Application of the proposed corrections leads to VSZ- and VS30-values (estimated from VSZ-to-VS30 semi-empirical relations) within ∼21% of the reference array velocity models. These rather small VS30 deviations from reference values, compared to similar studies, suggest that the P-wave seismogram method can provide reliable VS30 estimates for existing large-scale recording networks for which measured values are not available.

Rapid and reliable earthquake magnitude estimation is crucial for disaster management, scientific research, and resource conservation across multiple fields, especially during the initial stages of event detection. The most reliable traditional methods rely on complete waveform records, including earthquake epicenter distance and waveform amplitude, which can delay magnitude assessment. Machine learning techniques offer a promising avenue for capturing nonlinear relationships within seismic data, enhancing both information extraction and timeliness in magnitude estimation. In this study, we introduce an Attention-based machine learning model for MAGnitude estimation (AMAG) tailored for real-time earthquake monitoring. Using two independent datasets for training and testing, the results demonstrate the efficacy of our method in accurately predicting earthquake magnitudes. The magnitude prediction errors on the two test sets are −0.2 and −0.1, respectively, and the picking errors for both are 0.02 s. Our approach can be used directly for different time windows and signal lengths (at least 1 s) without retraining. We investigate the influence of signal-to-noise ratio, distances, and the integration of attention mechanisms. The attention mechanism facilitates the identification of the first motion and provides insights into the network’s focus areas, thereby establishing a relationship between waveform characteristics and earthquake magnitude. In addition, we systematically explore the impact of network architectures, loss functions, and signal lengths on prediction performance. Our findings reveal that a network with a depth of four layers and a convolution kernel size of five yields optimal prediction accuracy, with mean square error identified as the most effective loss function. When the input waveform is six seconds long, with equal durations of noise and signal, the model’s prediction accuracy is optimized. Our study underscores the potential of machine learning-based magnitude estimation for real-time earthquake monitoring, offering novel opportunities to mitigate natural disaster impacts, minimize casualties, and safeguard lives and property.
Improving the Resolution of Array-Based Surface-Wave Phase Velocity Tomography by Correcting for Array-Averaging Effects

Published: February 2025

In recent years, the development of array-based surface-wave technology has brought ambient noise surface-wave imaging into the era of overtone surface waves. Overtone surface-wave dispersion curves offer additional constraints in inversion, significantly enhancing depth resolution, especially for low-velocity zones. However, these methods require noise cross-correlation functions from dozens of stations for each dispersion extraction. Previous imaging work used dispersion curves extracted from the subarray to represent the average structure beneath the subarray, obtaining a 1D velocity structure at the center point of different subarrays. This approach can lead to observed phase velocity values and distributions being influenced by the subarray’s size due to the averaging effect. In this work, we try to establish the relationship between the phase velocity distribution and the observed dispersion curves using simple approximations. Then, the averaging issue can be effectively addressed through a spatial phase-velocity further inversion, for which the phase velocity distribution is treated as the inverted model and the phase velocities obtained by subarrays as the observed data. Synthetic tests demonstrate that this inversion effectively enhances the horizontal spatial resolution of the array surface-wave method and corrects the observed absolute velocity values. We also apply this method to the eastern South China block with our previously developed surface-wave method, the frequency–Bessel transform method, supplementing more essential details for the midcrustal low-velocity zones. Furthermore, the inversion enables a chessboard test to estimate the horizontal resolution of the inverted phase velocity distribution, addressing a key concern in array-based surface-wave imaging.

Published: February 2025

There is growing interest in floating offshore wind turbine (FOWT) technology, where turbines are installed on floating structures anchored to the seabed, allowing wind energy development in areas unsuitable for traditional fixed-platform turbines. Responsible development requires monitoring the impact of FOWTs on marine wildlife, such as whales, throughout the operational lifecycle of the turbines. Distributed acoustic sensing (DAS)—a technology that transforms fiber-optic cables into vibration sensor arrays—has been demonstrated for acoustic monitoring of whales using seafloor telecommunications cables. However, no studies have yet evaluated DAS performance in dynamic, engineered environments, such as floating platforms or moving vessels with complex, dynamic strain loads, despite their relevance to FOWT settings. This study addresses that gap by deploying DAS aboard a boat in Monterey Bay, California, where a fiber-optic cable was lowered using a weighted and suspended mooring line, enabling vertical deployment. Humpback whale vocalizations were captured and identified in the DAS data, noise sources were identified, and DAS data were compared to audio captured by a standalone hydrophone attached to the mooring line and a nearby hydrophone on a cabled observatory. This study is unique in: (1) deploying DAS in a vertical deployment mode, where noise from turbulence, cable vibrations, and other sources posed additional challenges compared to seafloor DAS applications; (2) demonstrating DAS in a dynamic, nonstationary setup, which is uncommon for DAS interrogators typically used in more stable environments; and (3) leveraging looped sections of the cable to reduce the noise floor and mitigate the effects of excessive cable vibrations and strain. This research demonstrates DAS’s ability to capture whale vocalizations in challenging environments, highlighting its potential to enhance underwater acoustic monitoring, particularly in the context of renewable energy development in offshore environments.
Earthquake Location with Distributed Acoustic Sensing Subarray Beamforming with Implications for Earthquake Early Warning
Authors: Ben-Zeev Shahar , Lior Itzhak
Published: February 2025

Earthquake location is a crucial component of earthquake monitoring and earthquake early warning (EEW) systems. The emerging distributed acoustic sensing (DAS) technology allows array measurements of strain rate in an unprecedented spatial resolution and over long distances. Hence, it holds great promise for earthquake location evaluation. Yet, many existing fibers that are in use for seismological applications are of linear geometry and often result in ambiguous location estimation. Here, we show that time-domain beamforming and phase arrival-time difference, applied to many short DAS subarrays, can produce robust evaluations of source locations. The aggregation of beams and phase arrival times from many segments along the fiber constrains the epicenter location. We demonstrate the method using two local small-size earthquakes recorded on a 66 km fiber. We further show the method’s applicability for real-time EEW.
Prevalence of activity limitation due to work related musculoskeletal disorder in long standing metro station workers
Authors: Gayathri  , N. Harshitha
Published: February 2025

Background: The study sought to estimate the prevalence of work-related musculoskeletal disorders among metro workers in Bangalore using the REBA scale, ICF, and WHO-QOL. Workers at metro stations must perform strenuous jobs, such as standing for long hours or walking, performing repetitive activities, and maintaining awkward postures during work hours. They are therefore more prone to musculoskeletal disorders (MSDs) and their symptoms. Objective was to determine the prevalence of activity limitations among long-standing metro station workers with WRMSD.
Methods: A cross-sectional study involving 100 Bangalore metro station workers aged 20-45 were assessed for their activity limitation using ICF core sets and REBA score derived from captured postures of most awkward positions maintained by the subjects for more than a minute. Consent was obtained and WHO-QOL BREF questioner was used to evaluate their overall productivity.
Results: The findings revealed that 67% of participants had WMSDs, and that there were significant relationships between musculoskeletal discomfort and demographic traits. The results highlight the need for targeted ergonomic interventions and workplace changes in order to improve the health of workers at metro stations.
Conclusions: In conclusion the study revealed a high percentage of prevalence of WRMSD among long standing metro station workers as well as a negative association between age and activity restriction, suggesting that as age increases, the amount of activity limitation tends to decrease.
