Seed characterisation and micromorphology of taxa of the genus Crocus (Iridaceae) in Bulgarian flora
Authors: Raycheva Tsvetanka , Stoyanov Kiril
Published: January 2025

The morphology of seeds and SEM structure of epicuticular formations of the seed testa of 14 species of Crocus genus known so far for Bulgaria have been studied. The results have demonstrated great diversity. This study provided additional characteristics for the taxonomy of the crocuses that would be particularly useful for distinguishing some morphologically similar and critical species. A great diversity has been observed in the sculpturing pattern of the seed surface in the taxa studied. Discreet characters relevant to Crocus taxonomy have been revealed. The established differences in the microsurface structures correspond to differences in the metric and qualitative characteristics of the seeds in the studied taxa. Some of the investigated species of the genus Crocus in Bulgaria have been investigated for the first time by seed morphology. It follows from the obtained results that the morphological characteristics of the seeds are closely related to the taxonomy of the genus. As a result of the research, we proposed an analytical key for the recognition of the characteristics of the seeds.
Poéticas del afuera: un nuevo marco lírico
Authors: Núñez Marco Antonio , Ortega Antonio
Published: January 2025

En la poesía española se viene dando una rotura textual con las diversas oleadas de epígonos que la asolan y la siguen arruinando (tanto de las más jóvenes, con una supuesta renovación que suena a lo mismo; como de las anteriores que siguen fomentando la inercia y la complacencia). Bajo la denominación de Poéticas del afuera hemos reunido una serie de poetas que trasgreden las líneas habituales de los caminos trillados y que han creado un campo poético diferente, discordante y propio. Se trata de un marco que se bifurca en aquellos que abren fugas en el texto poético mediante la intrapoesía y aquellos que lo agujeran por medio de mostrar el proceso creativo del mismo. De esos autores sobre todo se comentará su estilística, centrada principalmente en su pensamiento poético.

Authors: Garriga Baraut Teresa , Escoda Delgado Nuria , Heredia Vives Aleix , Alcolea López Justo M.
Published: January 2025

Introducción. El uso de ácido hialurónico (AH) en tratamientos médico-estéticos faciales sigue aumentando sin cesar. Aunque el AH se considera un relleno dérmico seguro, en la literatura ya se han descrito casos de reacciones adversas (RA), incluyendo las de hipersensibilidad (RH), tras su inyección. El objetivo de esta revisión sistemática es analizar la literatura médica publicada hasta el momento sobre las RA al AH inyectado en la cara, para determinar la prevalencia de las RA y de las RH, así como su asociación con la zona de aplicación.

Materiales y método. Se ha realizado una búsqueda sistemática en bases de datos (Medline, PubMed y Cochrane) hasta agosto de 2024. Se incluyeron casos clínicos, series de casos y artículos originales en inglés que informaran sobre RA a las inyecciones faciales de AH, incluyendo las RH. Se excluyeron revisiones, estudios experimentales y literatura repetida.

Resultados. De los 124 artículos resultantes de la búsqueda inicial, 20 cumplieron los criterios de inclusión. Se informaron dos casos de hipersensibilidad inmediata tipo I y se analizaron las reacciones retardadas en 241 pacientes, siendo los nódulos y el edema las RA más frecuentes. Se observó una posible asociación con enfermedades autoinmunes e infecciones.

Conclusiones. Las RA y RH al AH, aunque poco frecuentes, suceden y deben conocerse. Se necesitan más estudios, para comprender los factores de riesgo asociados y sus mecanismos fisiopatogénicos, a fin de desarrollar productos más seguros.

Published: January 2025

This research work was conducted in 2023 to identify preferred traits of Triticum aestivum and Triticum durum wheat among farmers in North-Western Plain Zone (NWPZ) and Central Zone (CZ) of India, respectively. The method of sampling used for choosing 120 farmers was multi-stage random sampling, of which 60 farmers were from Aligarh, Uttar Pradesh, and 60 farmers were from Dewas, Madhya Pradesh. SPSS was used to perform quantitative conjoint analysis of the preferences for plant height, crop duration, irrigation requirement, pest attack, grain yield, grain size, and straw yield. From observations taken during the interviews, farmers preferred early maturity, species or hybrids with high grain and straw yield, large grain size, high market price, low water usage through irrigation, and disease or pest attack rating. Grain yield and straw yield, grain size, and market rate had a very high influence on preference, while plant height had the least influence. These insights can inform future wheat breeding programs aligned with preferences by farmers to improve food production in the NWPZ and CZ regions. Understand what these preferences are and formulate varieties that will meet the requirements for better food production.

Published: January 2025

This Arduino program is designed for measuring ammonia (NH3) gas concentrations using an MQ gas sensor. It reads the sensor's analog output connected to pin A0, calculates the sensor resistance (Rs) based on the voltage drop across the sensor and predefined resistor values. The program compares the sensor resistance to a reference resistance (Ro) to calculate the ratio (Rs/Ro), which is used to estimate the gas concentration. Using a formula derived from the sensor's calibration data (slope 'm' and intercept 'b'), the program calculates the ammonia concentration in parts per million (ppm).The data, including the ammonia concentration and corresponding voltage, is displayed on a 16x2 LCD screen. The program also features a safety mechanism: if the ammonia concentration exceeds a set threshold (50 ppm), a buzzer and a fan are activated as an alert system. Otherwise, the buzzer and fan remain off. This process continuously repeats, providing real-time monitoring of ammonia levels

Authors: Nandan S  , Mr. Pradeep Nayak  , Amar B M  , Manikanta  , Karthik Madakari T P
Published: January 2025

Intrusion Detection Systems (IDSs) are critical tools in the realm of cybersecurity, designed to detect and respond to unauthorized access, malicious activities, and potential threats within network or host environments. These systems monitor and analyze network traffic or system behavior, identifying patterns that may indicate security breaches. IDSs are classified into various types, including Network-based (NIDS), Host-based (HIDS), and Hybrid systems, each offering distinct advantages based on the nature of the monitored environment. Signature-based detection focuses on identifying known threats, while anomaly-based detection aims to detect unknown or novel attacks by analyzing deviations from normal system behavior. Despite their effectiveness, IDSs face challenges such as false positives, resource constraints, and the need for constant updates. The integration of IDSs with complementary tools, such as firewalls and Security Information and Event Management (SIEM) systems, enhances their capabilities. This abstract highlights the importance of IDSs in maintaining robust cybersecurity defenses, emphasizing the need for continuous adaptation and improvement to combat ever-evolving threats and safeguard organizational systems and data

Authors: Butarovich D. O. , Panshin M. V. , Panshin A. V.
Published: January 2025

Introduction (problem statement and relevance). Today, electric buses are used as one of the main transport means on the routes of Moscow. It has been found that operation of electric buses significantly differs from operation of conventional buses equipped with an internal combustion engine. In this regard the need to define the initial data in terms of the electric bus speed on the route, power supplied and torque distribution per unit of time on the transmission shafts determining operational loading modes of the electromechanical transmission gear, remains a pressing issue. Thus, it is necessary to perform a comprehensive mode-metering of the transmission as the examined vehicle drives the city routes.

The purpose of the study is to form initial data for determination of the load mode parameters of the transmission being developed or examined.

Methodology and research methods. The proposed method of forming the initial data consists in reading the information coming to the electronic unit of wireless message transmission via the Controller Area Network protocol (CAN messages) along with the functions of collecting telematics information with further processing to represent it in the form of graphs of distribution of torque and speed over time.

Scientific novelty and results. The mode-metering of loading of an electromechanical transmission of urban wheeled electric transport when driving on the route, using the Controller Area Network bus embedded in the vehicle, allowed obtaining a set of data on distribution of vehicle speed and torque occurring in the transmission over time.

Practical significance. The developed method of mode-metering of electromechanical transmissions of urban wheeled electric transport can be applied in analysis of transmission durability on various electric bus routes in Moscow while excluding creation of expensive specialized measuring complexes.

Authors: Aliyu Aminu , Muhammad Yahaya
Published: January 2025

This study aims to investigate the efficacy of Universal Design for Learning (UDL) interventions in enhancing engagement among pre-service teachers. Traditional instructional methods often neglect learner diversity, resulting in low engagement and academic achievement. UDL offers a proactive framework that incorporates Multiple Means of Engagement, Representation, and Expression to create inclusive learning opportunities for all students. Methods: A quasi-experimental research design was employed, involving a sample of 244 pre-service teachers, randomly assigned into two groups: a UDL-based instruction group (n = 122) and a traditional instruction group (n = 122). Participants’ engagement levels were measured using a validated UDL-based Engagement Scale. Results: The analysis revealed a significant difference in engagement levels between the two groups (p < .05), with the Experimental group exhibiting higher mean engagement scores (M = 70.48, SD = 9.59) compared to the traditional instruction group (M = 56.17, SD = 9.49). Conclusions: These findings provide empirical evidence that UDL-based interventions significantly enhance engagement among pre-service teachers. By addressing the diverse needs of learners, UDL frameworks can break down barriers to engagement, suggesting that their implementation in teacher education programs may lead to improved academic outcomes and better preparedness for future educators in diverse classroom settings.

Published: January 2025

Este artigo apresenta a trajetória da pesquisadora Fernanda Nascimento Almeida.

Minha história na bioinformática foi se construindo pouco a pouco, em um caminho sinuoso que me levou a explorar diferentes áreas e desafios. Tudo começou com a escolha pela citogenética na graduação, onde tive a primeira noção de como a biologia molecular se entrelaça com a tecnologia. Naquele momento, eu nem imaginava que isso abriria portas para a bioinformática, mas, aos poucos, fui mergulhando cada vez mais nesse universo fascinante. O contato com técnicas de sequenciamento de genes e a análise de dados genômicos foi me revelando como a computação poderia ser uma aliada poderosa da biologia. Ao longo dos anos, com o mestrado, doutorado e pós-doutorado, fui consolidando esse caminho, que de início parecia cheio de curvas, mas que, no fim das contas, me levou exatamente onde eu queria estar: desenvolvendo soluções para a saúde, a agropecuária e a ciência de dados. A bioinformática, para mim, é esse espaço dinâmico, onde a curiosidade e a ciência de vanguarda se encontram, e, mesmo com os desafios – seja como mulher, mãe ou pesquisadora – sigo com a mesma paixão e vontade de aprender.

Preparing for an extensive ∆14CO2 flask sample monitoring campaign over Europe to constrain fossil CO2 emissions
Authors: Gómez-Ortiz Carlos , Monteil Guillaume , Karstens Ute , Scholze Marko
Published: January 2025

Abstract. During 2024, an intensive Δ14CO2 flask sampling campaign is being conducted at 12 stations across Europe as part of the CO2MVS Research on Supplementary Observations (CORSO) project. These Δ14CO2 samples, combined with CO2 atmospheric measurements, aim to improve fossil CO2 emission estimates across Europe through inverse modeling. In this study, we perform a series of Observing System Simulation Experiments (OSSEs) to assess the added value of this intensive campaign and explore different sampling strategies for optimizing fossil fuel emission estimates. The strategies focus on selecting samples for inversions based on their fossil CO2 and nuclear 14C composition. We evaluate three sampling approaches: (1) a base scenario using uniform sampling without specific selection criteria, comparing current methods with the addition of flask samples; (2) a strategy that selects samples with high fossil CO2 content; and (3) a combined approach that accounts for nuclear 14C contamination to reduce potential biases from nuclear facilities. Our results suggest that higher sampling density improves the accuracy of fossil CO2 estimates, especially during low-emission periods, such as summer. Increasing the number of samples reduces uncertainty, enhancing the robustness of inverse modeling outcomes. Selecting samples based on fossil CO2 contamination further refines the estimates, but the most significant uncertainty reduction occurs when nuclear contamination is also considered. This combined strategy effectively mitigates biases in regions with high nuclear activity, like France and the UK. These findings highlight the importance of increasing sampling frequency and strategically selecting samples to improve fossil fuel emission estimates across Europe.

Abstract. Wetlands perform a vital array of ecosystem functions, but up to 50 % of global wetlands have been lost and those that remain are under ongoing threat from development pressures. Accurate and comprehensive maps are critical for the management and protection of wetland resources. Conventional methods for wetland mapping are time consuming and resource intensive, and the common mapping methods that rely on the inspection of aerial imagery often miss forested and other wetland types that do not have a distinctive visual signature, i.e. cryptic wetlands. The use of machine learning and spatial data to map wetlands is a growing field that promises a fast and efficient complement to conventional methods and improved detection of forested and other cryptic wetlands. In this paper we demonstrate the use of a random forest model to generate a large-scale, state-wide map of wetland probabilities in the Commonwealth of Massachusetts, using widely available open source software and publicly accessible data. Through this model we also test the efficacy of multi-scale predictors, including not only terrain derivatives used in previous research but also multi-scale implementations of soil, vegetation, and spectral data. The random forest was trained on the official Massachusetts wetland inventory, and achieved an overall accuracy rate of 92 % relative to that dataset. The model showed particular promise in detecting cryptic wetlands by identifying an additional 40 % of probable wetland area statewide, and an additional 46 % of forested wetland specifically. The use of diverse multi-scale predictors was supported by model performance, variable importance measures, and the feature selection process. This strategy for improving detection of cryptic wetlands and creating better estimates of wetland extent, using non-proprietary software and data, will be a vital adjunct to conventional methods for wetland mapping and monitoring.

Abstract. Existing process-based models for simulating coastal foredune evolution largely use the same analytical approach for estimating wind-induced surface shear stress distributions over spatially variable topography. Originally developed for smooth, low-sloping hills, these analytical models face significant limitations when the topography of interest exhibits large height-to-length ratios and/or steep, localized features. In this work, we utilize computational fluid dynamics (CFD) to examine the error trends of a commonly used analytical shear stress model for a series of idealized two-dimensional dune profiles. It is observed that the prediction error of the analytical model increases compared to the CFD simulations for increasing height-to-length ratio and localized slope values. Furthermore, we explore two data-driven methodologies for generating alternative shear stress prediction models, namely, symbolic regression and linear, projection-based, non-intrusive reduced-order modeling. These alternative modeling strategies demonstrate reduced overall error but still suffer in their generalizability to broader sets of dune profiles outside of the training data. Finally, the impact of these improvements on aeolian sediment transport fluxes is examined to demonstrate that even modest improvements to the shear stress prediction can have significant impacts on dune evolution simulations over engineering-relevant timescales.

Although nearly 600,000 people experience homelessness in the United States (U.S) every year, efforts to address this public health crisis are limited by the underperformance of standard methods to estimate localized and nationwide homelessness. Recent studies suggest social media activity can function as a proxy for measures of state-level public health, detectable through straightforward applications of natural language processing. We present the results of our efforts to apply this approach to estimate homelessness at the state level throughout the US during the period 2010-2019 and 2022 using a dataset of roughly 1 million geotagged tweets containing the substring “homeless.” Correlations between homelessness-related tweet counts and ranked per capita homelessness volume, but not general-population densities, suggest a relationship between the likelihood of Twitter users to personally encounter or observe homelessness in their everyday lives and their likelihood to communicate about it online. An increase in the log-odds of the word “homeless” appearing in an English-language tweet, as well as an acceleration in the increase in average tweet sentiment, suggest that tweets about homelessness are also affected by trends at the nation-scale. Additionally, changes to the lexical content of tweets over time suggest that reversals to the polarity of national or state-level trends may be detectable through an increase in political or service-sector language over the semantics of charity or direct appeals. While a computational approach to social media analysis may provide a low-cost, real-time dataset rich with information about nationwide and localized impacts of homelessness and homelessness policy, we find that practical issues abound, limiting the potential of social media as a proxy to complement other measures of homelessness.
