Authors: Ogungbemi Kayode Idowu , Adedokun Margret Bose , Oyebola Olusola Olurorimi
Published: May 2024

Background
This work investigates radon activities in administrative offices in five different floors to ascertain annual equivalent dose (AEqD) and excess lifetime cancer risk due to gamma radiations on the office workers.
Method
RAD7 an electronic radon detector manufactured by Durridge Co. USA calibrated in-house was used to measure the indoor radon concentration levels in offices of the Administration block.
Results
Mean radon concentration from offices studied ranged from 134.72 Bqm-3 − 536.98 Bqm-3in all the offices. The mean of the annual effective dose due to 222Rn progeny (AEDR) in mSv/yr. is highest in GFL this value is 2.344 x 10− 3 mSv/yr. and it’s lowest at the LFL with the value of 1.010 x 10− 3 mSv/yr. The lung cancer cases mean, maximum and the 95th percentile per million people values obtained from offices and the obtained values are 85.81, 11.44, and 11.21.
Conclusion
The obtained values were lower than the public limit of 1mSvy-1 as recommended by ICRP, and this findings show a significant correlation between indoor radon effective doses obtained by other studies elsewhere.

Authors: Akinnubi Abiola , Alassad Mustafa , Amure Ridwan , Agarwal Nitin
Published: May 2024

Analyzing opinions, extracting and modeling information, and performing network analysis in online information studies are challenging tasks with multi-source social network data. This complexity arises from the difficulty in harnessing data across various platforms and the absence of a unified data modeling approach. Although social network analysis has used a multiplex approach to study complex networks, no previous work has integrated data from multiple social networks, knowledge graph fusion, and contextual focal structure analysis (CFSA) for an online study. This study has developed a multi-source graph model and applied a Cartesian merge to model relations across multiple documents, entities, and topics. We improved the information modeled with third-party data sources such as WikiData and DiffBot. This approach has created a multiplex network instance for CFSA detection, incorporating topic-topic, entity-entity, and document-document models. We applied this method to a dataset from the Indo-Pacific region and identified 40,000 unique focal sets of influential topics, entities, and documents. The top sets discussed economics, elections, and policies such as the Indo-Pacific Economic Framework, Ekonomi baru, #NKRIHargaMati, #IndonesiaJaya, and the Xinjiang Supply Chain. Our model tracks information spread across multiple social media platforms and enhances the visibility of vital information using various relationships. The results underscore the effectiveness of KG-CFSA in contextualizing large-scale information from multiple sources.
Off-Policy Asymptotic and Adaptive Maximum Entropy Deep Reinforcement Learning
Authors: Zhang Huihui , Han Xu
Published: May 2024

Maximum entropy deep reinforcement learning has shown great promise in tackling various challenging continuous tasks. By incorporating the maximum entropy framework, the goal is to introduce more randomness in action selection and improve the training process. However, there exists a tradeoff between efficiency and stability, especially when dealing with large-scale tasks with high state and action dimensions.In certain situations, it becomes necessary to constrain the temperature hyperparameter of the maximum entropy term to prevent instability, which can hinder convergence. In this study, we propose an algorithm that combines adaptive and asymptotic maximum entropy with actor-critic random policies.Specifically, we introduce a state-dependent adaptive temperature to accelerate the training process and include an additional term involving asymptotic maximum entropy to ensure stable convergence. These components are combined with the selected critic value to serve as the target Q-value and the surrogate objective in the policy evaluation and improvement steps.The adaptive and asymptotic maximum entropy algorithm demonstrates robust adaptation to the efficiency-stability tradeoff, providing increased exploration and flexibility to address saddle point problems. We evaluate our method on various Gym tasks, and the results indicate that our proposed algorithms outperform several baselines in the domain of continuous control.
Decoding Reddit Memes Virality
Authors: Sah Tanmay , Jordan Kayden
Published: May 2024

Understanding the elements that contribute to a meme's virality is crucial due to the significant role memes play in digital culture and communication. This study analyzed 16,968 memes from Reddit, which are now available on the Open Science Framework (OSF). It aimed to identify predictors of virality, focusing on both textual and image-based characteristics. Our findings indicate that memes featuring multiple objects, humans, or animals, and those utilizing less saturated colors such as light gray and dark gray, tend to achieve higher virality. Additionally, smaller thumbnail dimensions and the avoidance of surprise facial expressions are associated with higher virality. Notably, memes posted between 12 pm and 6 pm UTC show a significant increase in virality. Combining these predictors enhances the Area Under the Receiver Operating Characteristic Curve (AUC-ROC) of virality predictions, highlighting the complex interplay between content elements in meme dissemination.This research underscores the importance of a multifaceted approach in predicting meme virality and offers insights into effective social media strategies. Additionally, we provide an open-source codebase on GitHub to promote research transparency and reproducibility.

Authors: Gökçe Serdar
Published: May 2024

The M-type barium hexaferrite (\(\text{B}\text{a}{\text{F}\text{e}}_{12}{\text{O}}_{19}\)) nanoparticles were synthesized by polymethylmethacrylate (PMMA) assisted sol-gel process. PMMA was used as a template at \(\text{P}\text{M}\text{M}\text{A}/\text{B}\text{a}{\text{F}\text{e}}_{12}{\text{O}}_{19}\) weight ratio of 20/80, 40/60, 60/40% in the synthesis. The X-Ray Diffraction (XRD) and scanning electron microscopy (SEM) have been used to determine the structural, compositional and morphological features of particles. DC magnetic properties have been measured by using electron spin resonance (ESR) spectrometer and vibrating sample magnetometry (VSM) at room temperature. The dielectric, magnetic and microwave properties were studied by reflection/transmission technique in the coaxial waveguide at the frequency range of 2–18 GHz. The results show that the nanorod nanoparticles are ~ 200 nm in length and ~ 40–50 nm in width for the sample with \(\text{P}\text{M}\text{M}\text{A}/\text{B}\text{a}{\text{F}\text{e}}_{12}{\text{O}}_{19}\) weight ratio of 20/80. The minimum reflection loss value of rod-shaped nanoparticles achieves ~ -50 dB with bandwidth of 2.25 GHz at -20 dB.
WITHDRAWN: Performance of Plastic Aggregate along with Steel Slag in the Concrete through the Mechanical Tests and Microstructural Analysis
Authors: Rani Kavita , SENTHIL KASILINGAM
Published: May 2024

The demand on the utilization of the industrial by-product increased in order to preserve the natural resources and create a sustainable environment for the future generation. Therefore, the present study is focused on the utilization of industrial by-product electric arc furnace slag (EAFS) as the replacement of cement and fine aggregates whereas the plastic aggregate (PA) were replaced with the coarse aggregate. The optimization of the mix design was performed by replacing the cementitious slag (SAC) upto 50%, whereas the slag as the replacement of fine aggregates (SAFA) upto 70%. Also, plastic aggregates (PACA) were replaced with coarse aggregates upto 50%. It is concluded that the 30% replacement of cementitious slag and fine slag aggregate found optimum whereas the same found to be 50% in case of coarse aggregate replacement with plastic aggregate. Further, the combined effect of mix with 30% cement, 50% fine aggregate along with 30% of PA was studied. The flexural strength of mix SCFPA found to be 5.5 MPa whereas the same found to be 5.17 MPa in the mix PACA3 and it shows that the cementitious slag and slag fine aggregate contribute marginally on the resistance under flexure. The tensile strength of combined mixes such as SCFA, SCPA, SFPA and SCFPA was found insignificant, whereas the compressive strength of SCPA mix was found as the worst performer. Further, SEM, XRD and EDS analysis were also conducted in order to study the microstructure of the different mixes. The CSH, ettringite and portlandite were majorly observed and the calcium silicate hydrate is an important compound for measuring the strength and rheological properties of concrete. The ettringite (3CaO•Al2 O3 •3CaSO4 •32H2 O) having a needle-like crystals structure plays an important role in the setting time, strength development and shrinkage of concrete, whereas the portlandite identified as a cubical smooth structure works as a bonding agent.
A Mendelian randomization study of the causal relationships between immune cells and colorectal cancer
Authors: He Weihua , He Lan , Deng Lan
Published: May 2024

Background: The incidence of colorectal cancer (CRC) is increasing steadily. This is corroborated by increasing evidence that establishes a connection between the regulation of immunocytes and the advancement of CRC. However, the exact underlying mechanisms remain unclear. Hence, this study aimed to elucidate the link between immune cells and vulnerability to CRC through the application of Mendelian randomization (MR) analysis.
Methods Existing genome-wide association studies (GWAS) have provided summary data on immune cells and CRC in European populations. The ebi-a-GCST90018808 cohort was designated the discovery cohort, while the finn-b-C3_COLORECTAL cohort was the validation cohort. Only single nucleotide polymorphisms (SNPs) that satisfied the following conditions were selected as instrumental variables (IVs): a p-value less than 1×10–5, a linkage disequilibrium coefficient (r2) less than 0.001, and a linkage disequilibrium region width of 10000 kb. The cornerstone analytical methodology used was inverse variance weighting (IVW), which was reinforced by the MR-Egger method to assess the causality of effects. Heterogeneity analysis was performed utilizing I2 and Cochran's Q tests. To assess pleiotropy, the MR-Egger method's intercept was utilized, complemented by sensitivity evaluation through a leave-one-out approach. The two datasets were combined for meta-analysis to further validate whether the two immune cell traits were consistent between the two cohorts.
Results In the discovery and validation cohorts, a causal association was found between CD25 expression on unswitched memory B cells and CD25++ CD45RA- CD4 not regulatory T cell absolute count, resulting in a decreased risk of CRC. Heterogeneity analysis indicated I2 < 50% and P >0.05 according to Cochran's Q test, suggesting no heterogeneity among the IVs. The intercept obtained from the MR‒Egger analysis showed no significant difference from zero, suggesting a negligible influence of horizontal pleiotropy on the IVs. A meta-analysis was conducted to amalgamate the aggregated data from both datasets, further corroborating the influence of the two immune cell traits in mitigating CRC risk.
Conclusion The results from MR analysis reveal that CD25 expression on unswitched memory B cells and CD25++ CD45RA- CD4 not regulatory T cell absolute count are intricately associated with a reduced risk of CRC.
Evaluation of the spatial equality of the medical service function from the perspective of the life circle：A case study of Chengdu City
Authors: Zhu ran , Rong Zi-qi , Wang Hai-li
Published: May 2024

Background
At a time when life is starting to return to normal following the global pandemic, the medical service function as a key component of public infrastructure in livable communities still have an undeniable importance. In practice, however, due to a heterogeneity in the distribution of medical facilities, a significant spatial imbalance can exist in urban and country regions. By integrating the life circle theory and complex system theory, we try to propose a new framework to fill this gap and explain the formation mechanism of the medical service function equality. Furthermore, the feasibility of the framework was verified by evaluating the spatial equality of medical services of the primary, secondary, tertiary and total medical service function in Chengdu City, China.
Methods
Based on Z-score method, a quantitative method was constructed to quantitative detect the spatial pattern of Chengdu’s medical services. This method can help to accurately identify the spatial equality of the medical service function, thereby facilitating further refined policy formulation to improve these functions.
Results
The results for accessibility within the life circle indicate that 97.69% of the population and 63.76% of metropolitan Chengdu enjoy total access to medical services, but this desirable accessibility gradually decreases around the central line of Chengdu and the central areas of other districts and counties. The multi-center hierarchical structure of level II, level III and the total function reflects the fact that accessibility to medical facilities in the main urban areas is better than that in the surrounding counties, and in the central urban areas of these surrounding counties are better than that in their peripheral areas. the spatial equality for the total function, level III, and level II exhibits a clear hierarchical structure, namely core-edge pattern. Urban construction is gradually spread from the center to the outside, which fundamentally determines the skeleton of the spatial pattern of medical service facilities in Chengdu.
Conclusions
Findings of this research contribute new theoretical and methodological insights into addressing the spatial equality of public service functions in complex regional and urban system.
Visualization of Bipartite Graphs in Limited Window Size
Authors: Efrat Alon , Evans William , Köck Kassian , Kobourov Stephen , Miller Jacob
Published: May 2024

Bipartite graphs are commonly used to visualize objects and their features. An object may possess several features and several objects may share a common feature.The standard visualization of bipartite graphs, with objects and features on two (say horizontal) parallel lines at integer coordinates and edges drawn as line segments, can often be difficult to work with. A common task in visualization of such graphs is to consider one object and all its features. This naturally defines a drawing window, defined as the smallest interval that contains the x-coordinates of the object and all its features. We show that if both objects and features can be reordered, minimizing the average window size is NP-hard. However, if the features are fixed, then we provide an efficient polynomial time algorithm for arranging the objects, so as to minimize the average window size. Finally, we introduce a different way of visualizing the bipartite graph, by placing the nodes of the two parts on two concentric circles. For this setting we also show NP-hardness for the general case and a polynomial time algorithm when the features are fixed.
From a Radiologist’s Eye: a Case Report of Actinomycetoma of the Foot With Comprehensive Review of Literature
Authors: A Ebinesh
Published: May 2024

Background:Tropical diseases comprise of an array of communicable and non-communicable diseases that prevail in the tropical belt. Madura foot, classified as a tropical disease by WHO, is a chronic granulomatous disease that predominantly involves the skin and subcutaneous tissue, commonly affecting the lower limbs. We present a case of actinomycetoma with extensive review of the existing literature, focusing on diagnostic imaging.Case presentation:A 36-year-old female from eastern India presented with a six-month history of right foot swelling and a discharging wound. She was unsuccessfully treated with multiple courses of antibiotics in local hospitals. Upon referral, radiological investigations were performed for further evaluation. USG showed infiltrative hypoechoic soft tissue with nodular lesions showing targetoid appearance. MRI revealed infiltrative soft tissue with variable sized nodular lesion showing characteristic ‘dot-in-circle' appearance, prompting the diagnosis of pedal mycetoma. Actinomycetoma was confirmed on biopsy.Conclusions:Pedal mycetoma presents significant diagnostic and therapeutic challenges owing to its insidious progression and delayed diagnosis. Radiological imaging, particularly MRI, plays a pivotal role in diagnosis and staging of the disease, enabling detailed evaluation of soft tissue and bone involvement. The ‘dot-in-circle' sign observed on imaging is pathognomic and aids in accurate diagnosis. Early diagnosis facilitated by diagnostic imaging warrants improved therapeutic outcomes.

Authors: Kofie Samuel Nartey , Min-Zhang Ivy , Chen Kai , Percy Wei
Published: May 2024

The increasing need to protect individual privacy in data releases has led to significant advancements in privacy-preserving technologies. Differential Privacy (DP) offers robust privacy guarantees but often at the expense of data utility. On the other hand, data pooling, while improving utility, lacks formal privacy assurances. Our study introduces a novel hybrid method, termed PoolDiv, which combines differential privacy with data pooling to enhance both privacy guarantees and data utility. Through extensive simulations and real data analysis, we assess the performance of synthetic datasets generated via traditional DP methods, data pooling, and our proposed PoolDiv method, demonstrating the advantages of our hybrid approach in maintaining data utility while ensuring privacy.

Authors: Shao Yilu , Yuan Ma-Ke , Zhou Yang
Published: May 2024

We study entanglement negativity for evaporating black hole based on the holographic model with defect brane. We introduce a defect extremal surface formula for entanglement negativity. Based on partial reduction, we show the equivalence between defect extremal surface formula and island formula for entanglement negativity in AdS_33/BCFT_22. Extending the study to the model of eternal black hole plus CFT bath, we find that black hole-black hole negativity decreases until vanishing, left black hole-left radiation negativity is always a constant, radiation-radiation negativity increases and then saturates at a time later than Page time. In all the time dependent cases, defect extremal surface formula agrees with island formula.

Authors: Juarros-Basterretxea Joel , Rodríguez-Franco Luis , Herrero Juan , Rodríguez-Díaz Francisco Javier
Published: May 2024

Eysenck’s PEN model is one of the most relevant and fruitful models with empirical support, and continues eliciting a large research corpus. Nevertheless, the systematic limitations regarding the psychoticism dimension and questionable inclusion of social desirability as a personality dimension have limited the model. The current research aimed to estimate an alternativePEN model including social desirability as a control and test its validity and reliability. This sample consists of 2969 Spanish young adults. Confirmatory factor analysis was carried out to test the fitting of four different models tothe data. Once the best-fitting model was obtained, multiple-group analyses were carried out to assess the configural, metric, and scalar invariance of themodel across sexes. The results showed that the three-dimension PEN model and two-dimension EN model controlling social desirability best fit the dataand were invariant across sexes. Despite the apparent appropriateness of both models, the EN model controlling for social desirability is more appropriate due to the weakness of the P dimension.

Published: May 2024

The prevalence of type 2 diabetes among older people is increasing every year. The main pathogenetic mechanisms of type 2 diabetes in elderly patients include disruption of the intestinal microbiota, cellular aging, oxidative stress and mitochondrial dysfunction, immune and inflammatory processes. Short-chain fatty acids produced by the intestinal microbiota influence inflammatory processes in pancreatic β-cells. Cellular senescence causes the secretion of different cytokines, chemokines, growth factors and proteases, exacerbating the proinflammatory state and increasing insulin resistance of the tissues. Oxidative stress and mitochondrial dysfunction decrease the ATP synthesis process and increase the formation of reactive oxygen species. Changes in the immune system in elderly patients contribute to autoimmune processes and systemic inflammation. Clinical features of diabetes mellitus in old age include asymptomatic progression, impaired recognition of hypoglycemia, impaired cognitive function, and muscle atrophy. The progressive decline in β-cells function in type 2 diabetes requires insulin therapy in many patients. Biphasic insulins allow to control both basal and postprandial glycemia, are easy to use and are indicated for patients who have difficulty counting amount of carbohydrates. However, it is worth remembering a balanced approach to prescribing and deintensifying therapy.

Authors: Pinto Guedes Dartagnan , Lima Keila , De Paula Cintia
Published: May 2024

A pandemia de COVID-19 vem acarretando mudanças substanciais no comportamento da população e em desfechos de saúde. O objetivo do estudo foi analisar as tendências temporais de um conjunto de condutas de risco do estilo de vida autorrelatadas por professores do ensino básico de escolas públicas da cidade de Curitiba, Paraná, antes e durante o autoconfinamento imposto pela pandemia de COVID-19. Trata-se de um estudo observacional em que duas amostras de professores do ensino básico responderam questionário padronizado de autorrelato com itens sobre atividade física, tempo de tela, duração de sono, consumo de frutas/hortaliças, uso de tabaco e bebida alcoólica. Uma amostra respondeu as questões em período não-pandêmico (n = 376) e a outra amostra respondeu as questões um ano após início da pandemia (n = 294). Os achados sugerem que a pandemia de COVID-19 impulsionou fortemente alterações nas condutas de risco do estilo de vida, incluindo inatividade física, tempo excessivo de tela, duração insuficiente de sono, ingestão inadequada de frutas/hortaliças e consumo abusivo de bebida alcoólica. No período pandêmico a chance de maior exposição para inatividade física (OR = 2,07 [1,40 – 3,01]) e duração insuficiente de sono (OR = 2,19 [1,39 – 3,46]) mais que dobrou e, no caso do tempo excessivo de tela (OR = 2,99 [2,02 – 4,36]), triplicou em comparação com o período pré-pandêmico. Concluindo, ações de intervenção devem ser orientadas em uma perspectiva ampla e abrangente de educação em saúde, que atendam as condições de isolamento/distanciamento social dos docentes e da população em geral.

Published: May 2024

Acquired immunodeficiency syndrome is an infectious disease caused by human immunodeficiency virus (HIV). Pharmacological antiretroviral therapy, along with therapeutic monitoring of drug plasma concentrations, facilitates adequate and effective follow-up in each patient. Our main objective was to develop and validate a high-performance liquid chromatography with ultraviolet detector (HPLC-UV) bioanalytical method for the simultaneous quantification of plasma concentrations of three commonly used antiretrovirals in Colombia: efavirenz, lopinavir, and ritonavir. This method is intended for therapeutic drug monitoring in persons living with HIV locally or in developing countries. The method is selective, specific, accurate, precise, and stable over the concentration range of 250 and 20,000 ng mL-1 for the drugs. It was successfully applied to measure the plasma levels of efavirenz, lopinavir, and ritonavir in HIV patients, which ranged from 251.0 ± 10.4 to 7186.2 ± 10.2, 8188.2 ± 5.9 to 15,312.5 ± 6.6, and 246.1 ± 6.5 to 1189.0 ± 6.4 ng mL-1, respectively.
Walker’s Appeal... is the main manifesto of radical African-American abolitionism
Authors: Shumakov Andrey A.
Published: May 2024

This work is about one of the key episodes of African-American history and the history of American abolitionism associated with the publication in September 1829 in Boston of Walker’s Appeal, in Four Articles; Together with a Preamble, to the Coloured Citizens of the World. The appearance of this “revolutionary appeal” undoubtedly marked a new milestone in the development of the anti-slavery movement and the actual emergence of such a trend as radical African-American abolitionism. The reaction to the release of this document by the authorities of the Southern States can be called unprecedented in its scale and consequences. It found expression in the adoption of a number of repressive laws, which, in turn, marked the beginning of a period of prolonged reaction in the American South, which would end only after the end of the Civil War of 1861–1865. The significance of this event is difficult to overestimate. After almost two centuries, the figure of David Walker and his Appeal still arouse increased interest from Western researchers and not only. However, no serious works on this topic have been published in Russian historiography up to the present moment.
This study aims to identify and examine the causes and circumstances of the writing of the Walker’s Appeal…, to analyze the main provisions of this document and the consequences caused by its dissemination. In addition, the author pays special attention to the review of the historiography of this issue. The source base is newspaper publications, letters and bills of the period under review, as well as the text of the Appeal.
The methodological basis of the research consists of causal, historical-descriptive, historical-genetic, historical-typological, retrospective, and comparative-historical methods. The materialistic dialectic plays the main role, showing the development of the abolitionist movement in dynamics and the influence of related factors.
The author concludes that Walker’s Appeal… became an expression of the most important trend in the development of American abolitionism at the end of the first third of the nineteenth century. The appearance of this document clearly demonstrated the radicalization of the African-American community itself and its willingness to join the struggle for the abolition of slavery and its rights.
Dialect vocabulary with the roots of quantitative semantics in Vologda dialects
Authors: Ilyina Elenа N.
Published: May 2024

The article comments on the morphemic and word-formation structure of words with the roots of quantitative semantics on the material of the Dictio­nary of Vologda Dialects. Models of nominal, verbal and adverbial stems are characterized. The ways and means of forming words with quantitative roots are described, as well as the spectrum of word-forming meanings of derivative dialect words. Against the background of the general Russian patterns of their morphemic and word-formation structure, dialectal differences are revealed regarding the distribution of common Russian roots and affixes, as well as a wider range of their formal and semantic variation. Based on the study of the lexical composition of the nests of qualitative semantics and the structural organization of the dialect words included in them, conclusions are drawn about the specifics of the dialect language picture of the world: its anthropocentricity, pragmatism, traditionality and expressiveness.
“Lunar New Year” by A. Parkau: cultural memory
Authors: Arustamova Anna A. , Chunyu Gao , Kondakov Boris V.
Published: May 2024

This article considers the Russian émigré literature in China in the aspect of implementing the principles of intercultural communication and interaction between the cultures of Russia and China. Scholars began to study it in the 1990s, and currently the work of many Russian writers from Harbin and Shanghai remains unexplored.
Features of the interaction of national traditions are analyzed in the poem “Lunar New Year” (Chinese New Year) by the poet of the Russian diaspora — A. Parkau, published in the poetic book Unquenchable Fire. Her artistic world still is not in the focus of the scholars.
The poem “Lunar New Year,” included in the Bitter Paths cycle, is the artistic description of the Chinese holiday. Its content is determined by Chinese culture, and its artistic form is determined by the Russian poetic tradition. The article traces the connections of the poem with Chinese culture and philosophy, on the one hand, and with the contexts of the Russian poetry of the 19th century, expressed in poetic meters, on the other.
The authors of the article examine the compositional and semantic principles of organizing a book of poems and come to the conclusion that the analyzed poem is included simultaneously in several cycles — calendar, reflecting the life of nature, and social, expressing the existential ideas of emigrants, expressed with the motives of loneliness, and fear of death, among others.

Recent Advances in Technologies for Removing Nanoparticles from Water
Authors: Liang Yankai , Shah Kinjal J. , Sun Yongjun
Published: May 2024

Nanoparticles are widely used in manufacturing, daily life applications, and other fields
because of their unique properties. However, the nanoparticles that end up in surface water are difficult
to break down naturally and cause environmental hazards that cannot be ignored. In this paper,
the migration mode of nanoparticles in the environment was proposed, and the factors affecting the
removal efficiency of nanoparticles mainly include ionic strength, natural organic matter, surface
properties, etc. The common methods for removing nanoparticles mainly include coagulation precipitation
methods, activated sludge methods, membrane filtration methods, and adsorption methods. In
addition, new technologies such as photothermal removal and electro-adsorption have also been applied
to remove nanoparticles in water. In future research, combining the advantages of different
removal methods and using different methods interactively to remove nanoparticles in water could
become a new research direction.

Reestablishment of Zamia lawsoniana (Zamiaceae, Cycadales), an endemic species of Mexico, with first description of the ovulate strobilus
Authors: Nicolalde-Morejón Fernando , Martínez-Domínguez Lilí , González-Aguilar Marlon Aramis , Stevenson Dennis Wm.
Published: May 2024

Background and Aims: Zamia, with 86 species, is the most diverse Neotropical cycad genus. In Mexico, 18 species occur, of which 15 are endemics. These taxa are distributed from sea level to 1200 m a.s.l. Recently, the phenology of Zamia in wild populations from southern Veracruz and Tabasco was studied to evaluate the morphological patterns of reproductive structures. While these records have been considered as Z. loddigesii, a species with a wide distribution along the Gulf of Mexico, different populations do possess morphological differences. Based on these data, we reevaluated the synonymy of Z. lawsoniana, which was described in 1884 and synonymized with Z. loddigesii in 1995.
Methods: Botanical material was collected from three populations in Tabasco, ten in Veracruz and two in Oaxaca previously considered part of Z. loddigesii. Reproductive structures were measured at maturity in habitat. Populations were visited during 2022 and 2023 to record reproductive phenology. Herbarium specimens of Zamia lawsoniana and morphologically similar species (Z. loddigesii, Z. spartea and Z. stenophyllidia) were examined. A morphological description and an illustration for Z. lawsoniana were prepared. In addition, an identification key that included related species in terms of morphology, geography and phylogenetics was made.
Key results: Zamia lawsoniana is removed from synonymy and some taxonomic clarifications are made. In this context, we provide a complete description of pollen strobili, including the microsporophylls, range of vegetative morphological variation, and a botanical illustration. Additionally, the ovulate strobilus is described for the first time and a preliminary conservation status is proposed.
Conclusions: Based on morphological evidence of reproductive structures and vegetative characters, we propose the reestablishment of Zamia lawsoniana and its removal from synonymy with Z. loddigesii.

Background

The use of digital biomarkers through remote patient monitoring offers valuable and timely insights into a patient’s condition, including aspects such as disease progression and treatment response. This serves as a complementary resource to traditional health care settings leveraging mobile technology to improve scale and lower latency, cost, and burden.

Objective

Smartphones with embedded and connected sensors have immense potential for improving health care through various apps and mobile health (mHealth) platforms. This capability could enable the development of reliable digital biomarkers from long-term longitudinal data collected remotely from patients.

Methods

We built an open-source platform, RADAR-base, to support large-scale data collection in remote monitoring studies. RADAR-base is a modern remote data collection platform built around Confluent’s Apache Kafka to support scalability, extensibility, security, privacy, and quality of data. It provides support for study design and setup and active (eg, patient-reported outcome measures) and passive (eg, phone sensors, wearable devices, and Internet of Things) remote data collection capabilities with feature generation (eg, behavioral, environmental, and physiological markers). The back end enables secure data transmission and scalable solutions for data storage, management, and data access.

Results

The platform has been used to successfully collect longitudinal data for various cohorts in a number of disease areas including multiple sclerosis, depression, epilepsy, attention-deficit/hyperactivity disorder, Alzheimer disease, autism, and lung diseases. Digital biomarkers developed through collected data are providing useful insights into different diseases.

Conclusions

RADAR-base offers a contemporary, open-source solution driven by the community for remotely monitoring, collecting data, and digitally characterizing both physical and mental health conditions. Clinicians have the ability to enhance their insight through the use of digital biomarkers, enabling improved prevention, personalization, and early intervention in the context of disease management.

The human intestine is a diverse ecosystem populated by microbiota affected by several factors, including age. The aim of this research was to evaluate the effects of the probiotic powder Lactobacillus plantarum Dad-13 on the numbers of gut microbiota, short-chain fatty acids (SCFA), and fecal characteristics in healthy adolescents. This research was conducted at SMPN 1 Pangururan, Samosir, with a randomized, double-blind, parallel placebo-controlled trial. 54 healthy adolescents aged 13 to 14 were divided into two groups, one consumed a gram of skimmed milk powder (placebo group) and the other ingested powder containing L. plantarum Dad-13 with 1.18 × 109 CFU/gram (probiotic group). After 33 days of intervention, the height of placebo group (149.42 ± 5.03 cm) and probiotic group (154.37 ± 4.67 cm) increased significantly. Significant increases in body weight (44.35 kg ± 4.61 to 45.20 kg ± 4.78) and BMI (and 18.77 ± 2.12 to 18.99 ± 2.11) were observed in the probiotic group. In the probiotic group, the numbers of gut microbiota were not significantly affected (p > 0.05). The amount of SCFA and fecal characteristics of both groups showed no significant differences. Thus, the consumption of L. plantarum Dad-13 increased weight, height, and BMI but could not influence the numbers of gut microbiota, SCFA, and the fecal characteristics of healthy adolescents.

Este artigo tem por objetivo investigar os saberes pedagógicos musicais que constituem a identidade profissional de professores não especialistas em música. Com base na epistemologia da prática profissional de Maurice Tardif, realizou-se uma investigação qualitativa, no contexto de uma observação participante, que envolveu quatro professores de Arte, habilitados em Artes Visuais/Plásticas. O material empírico foi constituído por meio de questionários, entrevistas e notas de campo da observação participante. Os dados revelaram que os saberes pedagógicos musicais que constituem a identidade profissional dos professores estão relacionados ao planejamento das aulas, às estratégias de ensino, à articulação com outras áreas do conhecimento, às atividades práticas e à avaliação da aprendizagem.
Hacia una política social sobre la vulnerabilidad
Authors: Acevedo Alemana Jesús , Arteaga Basurto Carlos
Published: May 2024

Se puede entender como población vulnerable aquella que no puede atender sus necesidades por sus propios medios; es decir, la no satisfacción de las necesidades humanas fundamentales vuelve vulnerable a un individuo, a un grupo social o a una sociedad. Ahora bien, la vulnerabilidad no es cuestión de situación personal, sino de circunstancias sociales, de un fenómeno que se ubica en la estructura misma de una sociedad. No se trata de un asunto que pueda ser resuelto por el ser humano aislado por medio de su empeño personal, sino de un fenómeno estructural. Así pues, la vulnerabilidad justifica sobradamente la intervención del Estado como agente responsable de reconocer y establecer los planes estratégicos y las líneas de acción que necesariamente tienen que estar encaminados a resolver la problemática social, así como prevenir el futuro inmediato y mediato de su població
Trabajo social crítico antiopresivo. Una aproximación teórica y metodológica
Authors: Cornejo Pérez Aczel Fernando
Published: May 2024

A diferencia del trabajo social crítico, la crítica no siempre forma parte de la constitución integral en el ejercicio del trabajo social tradicional, pues al sustentarse en las políticas sociales del Estado, tiende a la institucionalización y en la mayoría de las ocasiones se vuelve meramente operativo en su accionar. La crítica es aquello que nos permite cuestionar el conocimiento, previo a la realización de un trabajo de intervención con una población. En este escrito se abordará la especificidad de una ramificación del trabajo social crítico: el antiopresivo, caracterizado por fungir como herramienta que opta por la liberación social de los sujetos ante las ataduras de las instituciones del Estado. En este sentido, se plantea una diferenciación entre esta postura y la tradicional. Y se enuncian los aspectos teórico-metodológicos que debe contemplar un trabajador social crítico. Asimismo, se establece la ruta teórico-referencial mediante la cual se introduce la práctica crítica en el trabajo social antiopresivo cargada de referencias antirracistas. También se discute su pertinencia para el quehacer profesional en la región latinoamericana, y la importancia del campo político para materializar la estrategia antiopresiva. Se concluye con la necesidad del enfoque crítico antiopresivo, no solo para la práctica profesional del trabajador social, sino para la emancipación de las sociedades latinoamericanas que viven en condiciones de desigualdad.

Authors: López Amador María de Jesús
Published: May 2024

El presente artículo tiene como propósito exponer algunas reflexiones y elementos de análisis sobre la importancia de la evaluación como practica especializada del trabajo social. Puesto que el marco de la evaluación de los programas y proyectos sociales es una de las herramientas base de la intervención del profesional de trabajo social. La evaluación en México tiene un marco normativo y legal con el que opera la política pública social; su importancia radica en que permite definir los problemas públicos que son prioritarios para un país y su ciudadanía, y que, a su vez, están orientados a resolver necesidades y demandas a través de los bienes y servicios públicos que se generan. El proceso metodológico que se siguió para elaborar el presente trabajo, consistió en la revisión de documentos teórico-metodológicos sobre la evaluación y la consulta de las normas jurídicas y leyes que regulan la evaluación en México, junto con su principal institución CONEVAL; así como el análisis del Plan Nacional de Desarrollo instrumento base de la planeación en México, y de los programas sociales en la administración actual. El contenido de este artículo aborda cuatro aspectos principales: La Evaluación de programas y proyectos sociales, aspectos teóricos metodológicos. La Política Pública: características y procesos, así como El Marco de la Evaluación en México; en el que también se presenta una reflexión sobre la Política de Bienestaren México y algunas directrices importantes para el trabajo social. Las políticas públicas y su incidencia en la vida social. Finalmente, se concluye con algunos aspectos claves vinculados al trabajo social.
El apoyo familiar en las tareas escolares. Presencia del descuido socio-psicológico
Authors: Aguilar Medina José Iñigo
Published: May 2024

En la siguiente investigación se analiza el comportamiento de 128 individuos de la Zona Metropolitana del Valle de México (ZMVM), para conocer cómo interactúan con sus menores en la realización de las tareas escolares. Este acto de auxilio es importante para el aprendizaje de los chicos. Pero, cuando se da una presión inadecuada puede producirles una carga extra de estrés que, además, se convierte en un nuevo obstáculo a superar. Dicha presión, con la que se busca asegurar el éxito escolar, puede causar daños psicológicos y emocionales, e incluso violencia física. Esto incrementa los niveles de ansiedad y preocupación en los menores, por lo que estas medidas resultan contraproducentes. Los resultados muestran que poco menos de tres cuartos de las familias encuestadas consideran bueno aplicar correctivos, y una de cada diez les dan manotazos. Mientras que, apenas la mitad supone adecuado premiar su desempeño. Además, se indican algunas maneras de intervenir para que la familia mejore sus formas de apoyo.
