Published: October 2024

This work presents a Brillouin amplification performance comparison of seed generation techniques using double-sideband suppressed carrier (DSB-SC) and single-sideband suppressed carrier (SSB-SC) modulations. The SSB-SC is obtained using an optical bandpass filter (OBPF) and in-phase and quadrature Mach-Zehnder modulator (IQ-MZM). All three techniques provide high amplification performance with optical signal-to-noise ratio (OSNR) enhancement of 37.47 dB, 33.14 dB, and 32.67 dB using DSB-SC, SSB-SC/OBPF, and SSB-SC/IQ-MZM, respectively. The best seed generation technique is using the DSB with a signal amplification of 62.47 dB. The technique presents ~4 dB higher OSNR enhancement due to the dual-energy transfer obtained from the beating process of the DSB than SSB. A ~3 dB OSNR reduction is found when pump linewidth (LW) was changed from 1kHz to 50 MHz, which suggests using a low-cost pump source whenever the OSNR reduction is not critical. The work also shows that the three techniques required 10 dBm stimulated Brillouin scattering threshold (SBST) to stimulate the process. An additional analysis of DSB-SC shows that a high-carrier suppression during the seed generation technique using MZMs is insignificant to the amplification performance. The high-carrier suppression produces a high seed signal power that distorts the Brillouin gain spectrum (BGS) and the pump depletion region, hence reducing the Brillouin gain (BG). Since carrier suppression is not a primary consideration, a cost-effective MZM with a modest extinction ratio requirement is allowed. The relaxed requirement of the pump’s linewidth and MZM’s extinction ratio suggest a cost-effective development of the SBS-based optical amplifier with narrow filter bandwidth.

Authors: Rodrigues Maria Eduarda Gomes , Costa Joanne Elizabeth Ferraz da , Palitot Esther Bastos
Published: October 2024

Introdução: a hanseníase é causada pelo bacilo Mycobacterium leprae e afeta pele e/ou nervos periféricos. Reações adversas às medicações utilizadas no tratamento da doença têm sido relatadas na literatura. Objetivo: relatar o caso de paciente que apresentou reação adversa grave à dapsona no tratamento da hanseníase. Descrição do caso: paciente do sexo feminino, 51 anos, buscou atendimento no ambulatório de dermatologia do Hospital Universitário Lauro Wanderley da Universidade Federal da Paraíba, vinculado à Empresa Brasileira de Serviços Hospitalares, com queixa de manchas em membros inferiores há três anos, sendo identificadas, em exame físico, máculas eritêmato-acastanhadas com alteração de sensibilidade em membros inferiores. Foi realizada biópsia das lesões e a baciloscopia de esfregaço dérmico, que confirmaram o diagnóstico da hanseníase, procedendo-se ao início da poliquimioterapia, esquema único. Após três semanas, a paciente apresentou anemia hemolítica causada pela dapsona, sendo necessária a suspensão da poliquimioterapia, esquema único e prescrição de dois hemoconcentrados e hidrocortisona endovenosa, com evolução satisfatória. Discussão: há relatos na literatura de reações adversas à poliquimioterapia, esquema único, com ênfase à dapsona. A anemia hemolítica corresponde a um dos efeitos adversos mais comuns. Porém, os baixos níveis de hemoglobina da paciente diferiram dos achados de estudos prévios, sendo necessária a suspensão das medicações. Considerações finais: o destaque trazido pelo caso enfoca a anemia severa, evidenciando a relevância de uma abordagem interdisciplinar e da atenção minuciosa aos pacientes sob tal esquema terapêutico.

Organizations should implement pilot projects to assess the effectiveness of blockchain in enhancing data security in their specific contexts. Policymakers should develop clear regulatory frameworks to support the adoption of blockchain technology across sectors.
Characteristics and outcomes of surgical clipping of ruptured intracranial aneurysms at a tertiary care institution in Trinidad & Tobago – a descriptive report
Authors: Seetahal-Maraj Panduranga , Arjoon Sharies , Ramnarine Narendra
Published: October 2024

ABSTRACT

Objectives
Reports on the management and outcomes of intracranial aneurysms are sparse from the English-Speaking Caribbean. This study aimed to determine the characteristics and outcomes of surgically clipped ruptured intracranial aneurysms undertaken by a single neurosurgeon, under the unique challenges faced in a low-resources setting.

Methods
The neurosurgical operative logbook from the period July 1st 2018 - July 31st 2021 was examined to identify all patients who had surgically clipped cerebral aneurysms at a tertiary care teaching hospital in Trinidad and Tobago. Patients’ charts were reviewed to assess risk factors such as hypertension, smoking, positive family history, aneurysm grades and types, including presenting Hunt and Hess (HH) Grade, modified Fisher CT Grade, time to definitive surgery and Glasgow Outcome Scale - extended (GOSE). 

Results
Twenty-six patients underwent open surgical aneurysmal clipping, between the ages of 20 – 73 years. Posterior communicating artery aneurysms (35%) and anterior communicating artery aneurysms (38%) were the most commonly encountered types of aneurysms. One half of patients were HH Grade 1, and 58% were Fisher Grade 4. Time to clipping ranged from 3 – 62 days, with a mean of 12 days. About 42% of aneurysms were clipped prior to the peak vasospasm period, while 61% were clipped within 14 days. Following the procedure, 62% of patients had GOSE score of 8 (maximum function).

Conclusion
Surgical clipping of ruptured intracranial aneurysms may yield good patient outcomes even in a low-resource setting, despite challenges faced due to limited resources and operating time. Clipping during peak vasospasm period did not result in worse outcomes. The establishment of a neurovascular service may be beneficial even in low-resource settings.

Authors: Barrett Kijana , Sawh Dayanand , Palmer Wayne , Williams Pierre , Chin See Charlene
Published: October 2024

Abstract

Objectives
To determine the prevalence of nail-stick foot injuries in children visiting the Bustamante Hospital for Children (BHC) in Jamaica, identify the time between injury and hospital presentation, identify the risk factors for injury and complications, identify the complications, and the association between time to presentation and complication rate.

Method
A retrospective cohort analysis of children between the ages of 0-12 years presenting to the BHC from July 1, 2015, to August 31, 2018, with nail-stick foot injuries was performed. Extracted data included demographics, date of injury and presentation, side injured, zone of injury, number of nail-sticks, footwear use during injury, treatment, date of hospital discharge and complications. Data were analysed to determine the factors associated with morbidity including complications.

Results
Two hundred and ten (210) children met the inclusion criteria. The prevalence rate was 6 patients per 1000 hospital admissions. The mean time to presentation was 2 days. Using Patzakis classification, 26, 76 and 66 persons had zone 1, 2 and 3 injuries respectively. The complication rate was 14.8%. Complications observed were abscesses (77.4%), retained foreign bodies (9.7%), osteomyelitis (6.5%), deep wound infection (3.2%) and cellulitis (3.2%). Children presenting after 2 days (p<0.0001) and zone 1 injuries (p=0.030) were more likely to have complications. Footwear was protective against complications (p=0.006).

Conclusion
Nail-stick foot injuries are frequent presentations at the Bustamante Hospital for Children. Boys older than 9 years are the greatest at-risk group. The most common complication is abscess formation and delays in presentation greater than 2 days were more likely associated with complications.

Abstract

Objective
We examined the demographic, clinical characteristics and indicators of poor outcomes among hospitalised adults with COVID-19 infection at the University Hospital of the West Indies, Jamaica.

Methods
A retrospective medical record review between March 10 and December 31, 2020 was done and demographic clinical data were collected.

Results
There were 218 males (mean age 59.5 years) and 144 females (mean age 55.7 years). Hypertension, diabetes mellitus, cardiovascular disease, obesity and chronic kidney disease were the most common comorbidities. Cough, shortness of breath, fever and malaise were the most common presenting complaints. Fifty-one per cent of patients were moderately to severely ill on admission; 11% were critically ill; 18% were admitted to the Intensive Care Unit (ICU). Death occurred in 62 (17%) patients (95% CI 13.6-21.4). Among obese participants, there were increased odds of  developing respiratory failure (OR 5.2,  p < 0.001), acute kidney injury (OR 4.7, p < 0.001), sepsis (OR 2.9, p =0.013) and the need for ICU care (OR 3.7, p < 0.001). Factors independently associated with increased odds of death were age (OR 1.03 per year, p = 0.013) and obesity (OR 2.26, p = 0.017). Mortality also correlated significantly with D-dimer > 1000 ng/mL (OR 2.78; p = 0.03), serum albumin < 40 g/L (OR 3.54; p = 0.03) and serum LDH > 485 U/L OR 1.92, p = 0.11).

Conclusions
Comorbidities were prevalent among COVID-19 cases in this study. Significant correlates of mortality were older age and obesity. Hypoalbuminaemia, elevated D-dimer and serum LDH at admission also portend a poor prognosis.

Moda y Stasis: el impacto fotográfico de Shoichi Aoki
Authors: Torres Jurado Juan Jesús
Published: October 2024

El 26 de abril de 2023, el fotógrafo japonés Shoichi Aoki (Tokio, 1955), lanzaba en formato digital una versión en inglés del primer número de la revista Fruits, publicada originalmente en Japón el 23 de junio de 1997. Aquel primer número, de apenas 85 páginas con fotografías a color, mostraba una selección de la moda callejera característica del barrio de Harajuku, en Tokyo. Las páginas de aquel primer número de Fruits eran un desfile de jóvenes ataviados con llamativos atuendos diseñados por marcas lujosas como Comme des Garçons o Vivienne Westwood, combinados con diseños propios de marcas locales como Harajuku Milkboy. Los siguientes 269 números de la revista Fruits la convirtieron en un referente de la fotografía de moda en el cambio de milenio. El lanzamiento de la versión en inglés en formato digital de aquel primer número puede ser entendido, por supuesto, como una ofrenda a una revista esencial, pero también como algo intrínseco a toda la obra de Shoichi Aoki: como apología de la fotografía de moda como documento indispensable para la comprensión de la estética urbana de un siglo XXI globalizado e hiperconectado.

Authors: Rubio Francisco , Llopis-Albert Carlos , Palacios-Marqués Daniel , García-Hurtado Dayanis , Zeng Souzhen
Published: October 2024

The contemporary university has evolved into a multifaceted institution, serving not only as a hub for research, professional training, and knowledge dissemination, but also as a pivotal component of economic machinery and societal advancement, especially within the context of globalization and intense competition. These institutions are now expected to significantly contribute to the socio-economic development of their surroundings, striving for excellence and competing within an increasingly interconnected global framework. To meet these heightened expectations, universities have undergone profound transformations over recent decades. This period of change is particularly notable within the Spanish context, mirroring the broader societal shifts since the onset of the democratic transition in 1975 through to the present day in 2024. This era has necessitated substantial reforms in university governance, equipping these institutions with the requisite tools to navigate and address emerging challenges effectively. A pivotal moment in this transformative journey was the enactment of the University Reform Law of 1983. Grounded in constitutional principles, this law marked a significant milestone in updating and revitalizing university education in Spain. After this, the Organic Law on Universities of 2001 further aligned the Spanish university framework with the broader European educational landscape, reinforcing the integration and competitiveness of Spanish institutions on a continental scale. However, to comprehensively grasp the magnitude and implications of these changes, it is essential to extend our analysis beyond the immediate past and explore the historical trajectory of Spanish universities over previous centuries. By examining this extensive historical context, we can better understand the foundational elements that have shaped the current state of higher education. This article aims to meticulously analyze the evolution of the Spanish university system, delineating the chronological progress, identifying persistent challenges, and engaging in a critical discourse on potential solutions. Through this examination, the article seeks to provide a nuanced understanding of the interplay between historical legacies and contemporary reforms, offering insights that are essential for shaping the future trajectory of higher education in Spain.
Corrosion Prediction Model for Long-Distance Pipelines Based on Nonlinear Feature Expansion-Northern Goshawk Optimization-Extreme Learning Machine
Authors: Du Xingyu , Dai Yujie , Zheng Bailing , zhu Xinqi
Published: October 2024

Pipeline corrosion is a significant challenge in oil and gas transportation, leading to economic losses and environmental hazards. Traditional detection methods are time-consuming and labor-intensive, necessitating the development of more efficient prediction models. This study introduces a hybrid model that combines nonlinear feature expansion (NLFE) and Northern Goshawk optimization (NGO) with an extreme learning machine (ELM) to predict the corrosion rate of natural gas pipelines. This model addresses the limitations of existing methods by enhancing data processing capabilities and improving prediction accuracy. NLFE captures feature relationships within the data, while NGO optimizes ELM by avoiding local minima and premature convergence. This hybrid method was validated using a dataset from a pipeline in Mexico, which contains 106 samples and 10 influencing factors, including oxidation-reduction potential, pipeline operation time, soil pH, grounding potential, and soil resistivity. The results indicate that the NLFE-NGO-ELM model outperforms traditional methods regarding prediction accuracy and robustness. Through an innovative combination of advanced feature augmentation and optimization techniques, this model effectively reduces the impact of noise and redundant information, capturing the intrinsic characteristics of the original data. The contributions of this study include addressing the sample size limitation through nonlinear feature expansion, optimizing the simulation with NGO, and validating the model’s feasibility using various performance metrics and Taylor diagrams. The NLFE-NGO-ELM hybrid model provides a promising solution for accurately predicting natural gas pipeline corrosion rates, enhancing pipeline safety and operational efficiency. This study lays the foundation for future research and practical applications in pipeline integrity management.

Abstract. The joint use of hourly resolution sampling and analyses with accelerated ion beams such as Particle Induced X-ray Emission (PIXE) technique has allowed the measurement of hourly temporal patterns of particulate matter (PM) composition at many sites in different parts of the world. The demand within the scientific community for this type of analysis has been continuously increasing in recent years, but hourly resolution samplers suitable for PIXE analysis are now discontinued and/or suffer from some technical limitations. In this framework, a new hourly sampler, STRAS (Size and Time Resolved Aerosol Sampler), was developed for the collection of PM10, PM2.5 or PM1. It allows automatic sequential sampling of up to 168 hourly samples (1 week), it is mechanically robust, compact, and easily transportable. To increase PIXE sensitivity, each sample is concentrated on a small surface area on a polycarbonate membrane. The comparison between the elemental concentrations retrieved by STRAS samples and samples collected using a standard sequential sampler operated in parallel shows a very good agreement; indeed, if both the samplers use the same kind of membrane, the concentrations of all detected elements are in agreement within 10 %.
Rain-on-snow events in mountainous catchments under climate change

Published: October 2024

Abstract. The frequency and intensity of rain-on-snow events (RoS) are expected to change in response to climate variations due to changes in precipitation, increase in air temperature and subsequent changes in the snow occurrence. In this study, we attributed these changes to the simulated variations in RoS events using a sensitivity analysis of precipitation and air temperature, and subsequent effects on RoS-related runoff responses were evaluated. We selected 93 mountainous catchments located in Central Europe across Czechia (60), Switzerland (26) and Germany (7), and used a conceptual hydrological model to simulate runoff components for 24 climate projections relative to the reference period 1980–2010. Climate change-driven RoS changes were highly variable over regions, across elevations, and within the cold season. The warmest projections suggested a decrease in RoS days by about 75 % for the Czech catchments. In contrast, the Swiss catchments may respond less sensitively, with the number of RoS days even increasing, specifically during the winter months and at higher elevations. Our projections also suggested that the RoS contribution to annual runoff will be considerably reduced from the current 10 % to 2–4 % for the warmest projections in Czechia, and from 18 % to 5–9 % in Switzerland. However, the RoS contribution to runoff may increase in winter months, especially for projections leading to an increase in precipitation, demonstrating the joint importance of air temperature and precipitation for future hydrological behavior in snow-dominated catchments.
Dust-producing weather patterns of the North American Great Plains
Authors: Evans Stuart
Published: October 2024

Abstract. The North American Great Plains are a semi-arid and windy environment prone to dust events that produce a variety of hazards to public health, transportation, and land degradation. Dust has substantial spatial variability across the plains, and the weather responsible for that dust is understudied in most of the plains, especially the North and East. Here we identify specific weather patterns associated with dust occurrence across the plains. We make use of an atmospheric classification that defines 21 weather patterns for the Great Plains that includes various stages of warm and cold frontal passages, northerlies, anticyclones, and summertime patterns not associated with mid-latitude cyclones. We use the time series of weather pattern to composite satellite daily dust observations from 2012–2021. We calculate average dust occurrence for each weather pattern, the contribution of each pattern to local dust loads, and identify the specific weather patterns most important to each location and subregion. We find no single weather pattern is responsible for dust occurrence in the plains, but that different patterns are responsible for dust in different subregions of the Great Plains. Passing cold fronts are most responsible for dust events in western Texas and New Mexico, southerlies are responsible in the northeastern plains of from Iowa to the Dakotas, and summer weather patterns produce the majority of dust in the High Plains from Colorado to Canada. Identifying the dust-producing weather patterns of particular subregions is a valuable step toward understanding dust variability and improving dust predictions, both present and future.
Storm frequency, magnitude, and cumulative storm beach impact along the US east coast

Abstract. This study extracted historical water level data from 12 National Oceanographic and Atmospheric Administration tide gauge stations, spanning the period from the early 20th century to 2022 from central Maine to southern Florida, in order to determine if temporal and spatial trends existed in the frequency and magnitude of storms along the US Atlantic Ocean coast. We used the Storm Erosion Potential Index (SEPI) to identify and quantify storms. We then use the timing and magnitude of those storms to determine the cumulative effect of storm clustering and large-magnitude storms on sandy beaches using the cumulative storm impact index (CSII) empirical model. The results from this study showed (1) no appreciable increase in storm frequency at any of the stations (except for sheltered stations susceptible to storm tide augmentation), (2) statistically significant but modest increases in storm magnitudes over time for 8 of the 12 tidal stations, (3) regional differences in storm magnitudes (SEPI) and cumulative storm impacts (CSII) characteristic of more frequent extratropical storms (temporal clustering) in the north and less frequent tropical storms in the south, and (4) a 4- to 10-year recovery period for regional beach recovery.

Abstract. Windstorms affecting Europe are among the natural hazards with the largest socio-economic impacts. Therefore, many sectors like society, the economy, or the insurance industry are highly interested in reliable information on associated impacts and losses. In this study, we compare – for the first time – estimated windstorm losses using a simplified meteorological loss index (LI) with losses obtained from a complex insurance loss (catastrophe) model, namely the European Windstorm Model of Aon Impact Forecasting. To test the sensitivity of LI to different meteorological input data, we furthermore contrast LI based on the reanalysis dataset ERA5 and its predecessor ERA-Interim. We focus on similarities and differences between the datasets in terms of loss values and storm rank for specific historical storm events in the common reanalysis period across 11 European countries. Our results reveal higher LI values for ERA5 than for ERA-Interim for all of Europe (by roughly a factor of 10), coming mostly from the higher spatial resolution in ERA5. The storm ranking is comparable for western and central European countries for both reanalyses, confirmed by high correlation values between 0.6 and 0.89. Compared to the Aon Impact Forecasting model, LI ERA5 shows comparable storm ranks, with correlation values ranging between 0.45 and 0.8. In terms of normalized loss, LI exhibits overall lower values and smaller regional differences. Compared to the market perspective represented by the insurance loss model, LI seems to have particular difficulty in distinguishing between high-impact events at the tail of the wind gust distribution and moderate-impact events. Thus, the loss distribution in LI is likely not steep enough, and the tail is probably underestimated. Nevertheless, it is an effective index that is suitable for estimating the impacts of storm events and ranking storm events, precisely because of its simplicity.
The optimum range of design axial induction factors for lowest levelized-cost of energy
Authors: Major Desirae , Schmitz Sven
Published: October 2024

Abstract. The present work proposes a new fatigue, aerodynamics, and cost-scaled turbine (FACT) blade design methodology. The basis of the FACT blade design is an objective function for change in levelized-cost of energy, ΔLCOE, as a function of design axial induction factor, a, that strikes a balance between increasing (or up-scaling) blade length and annual energy production while accounting for the additional cost and loading changes associated with a longer blade. In the process of developing the ΔLCOE objective function, new insights were gained about changes in capital cost and operations and maintenance cost with rotor up-scaling. As part of the capital cost function development, new engineering approximations for rotor mass are discussed that are suitable for large-diameter offshore wind turbines, which use improved materials technologies and manufacturing processes. Additionally, a detailed operations and maintenance model is developed using available wind farm reliability data. Furthermore, a relationship between turbine failure rate and damage-equivalent loads for failure-prone turbine subsystems is proposed. FACT rotor blade design points are identified using five reference wind turbines with power ratings of 10- to 22-MW as a baseline. Projected LCOE savings with a FACT rotor blade design are on the order of 5 % for an optimum design axial induction factor in the range of a = 0.21 and 0.27, thus falling between the low-induction rotor concept (a = 0.18) and the Betz optimum for maximum CP (a =  0.33).
