Authors: Tripathy Sujit , Mishro Pranaba , Mukherjee Vishwajeet
Published: January 2025

The use of microstrip antenna in microwave imaging for clinical assessment assistance has grown to a great extent. In this paper, an inset feed defected ground structure rectangular patch antenna with Rogers RT/duroid 5880 as the substrate material is designed in the frequency range of 4.80 GHz to 5.80 GHz for clinical diagnosis assistance. A four layered human head phantom model is used for evaluation in Ansys HFSS electromagnetic simulation. The suggested antenna is simulated over the head phantom model in three different positions i.e., over the head phantom model free of tumor, over the head phantom model with a superficial tumor region of 6mm radius and over the head phantom model with deep-seated tumor. The quantitative assessment of the proposed technique is conducted using different antenna parameters, such as: radiation efficiency, reflection factor, co-polarization, cross-polarization, surface current in comparison to the cutting-edge techniques. Graphical representation of the parameters is also presented in order to conclude the presence of tumor inside the brain.

Introdução: O Zika vírus é um flavivírus com elevada afinidade pelo sistema nervoso central, sendo capaz de ocasionar a Síndrome Congênita do Zika, na qual são identificadas alterações neurológicas pediátricas, com destaque para a microcefalia. Objetivos: Analisar os desfechos neurológicos na população pediátrica exposta ao Zika vírus (ZIKV). Métodos: Foi realizada uma revisão integrativa da literatura através de uma busca detalhada nas bases de dados PubMed, Lilacs, Scopus, MEDLINE e Periódicos CAPES, por meio de descritores DeCS e MeSH. Foram selecionados 20 artigos para o presente estudo, que incluíssem desfechos neurológicos em crianças e tivessem sido publicados nos últimos dez anos. Artigos metodologicamente inadequados foram excluídos ou que não abordassem o Zika Vírus, impactos neurais ou a população pediátrica. Resultados e Discussão: Os impactos neurológicos em crianças expostas ao Zika vírus reportados pelos artigos foram microcefalia severa, epilepsia, hipertonia e atrasos no desenvolvimento motor e cognitivo. A infecção no início da gestação apresentou maior gravidade em relação à morbimortalidade, mas sequelas também foram relatadas em infecções tardias, como perda auditiva e alterações comportamentais. Estudos destacam lacunas no acompanhamento de casos assintomáticos ao nascimento e reforçam a necessidade de pesquisas longitudinais. Conclusão: Os artigos analisados demonstram enfoque em populações específicas dentre a faixa pediátrica, sendo necessário novos estudos de caráter prospectivo que explorem a relação entre a infecção por ZIKV e desfechos neurológicos para melhor entendimento de seu percurso patológico e delineamento do prognóstico.

O estudo detalha o monitoramento do volume (m3) de troncos submersos presentes no rio Madeira próximos à Usinas Hidrelétricas (UHE). O deposito desse material foi observado ao longo de um período na região da UHE de Jirau. Para a coleta de dados foi utilizado o sistema SeeSub®/Venturo acoplado a uma embarcação. O SeeSub®/Venturo é um sistema de inspeção subaquática que usa tecnologia hidroacústica. Isso possibilitou a visualização em uma única imagem da totalidade da área inspecionada, tornando a verificação da integridade de estruturas um processo seguro e altamente confiável. A atividade detalhou (temporal e espacial) o volume de material lenhoso submersos nas regiões a montante e jusante da catenária dos antigos sistemas de Log Boom da UHE Jirau. O período de atividade na obtenção de dados ocorreu entre abril de 2021 a maio de 2022 com frequência semanal. A análise dos dados evidenciou diferenças entre a margem direita e esquerda. Na margem direita, uma tendência de redução da quantidade de troncos submersos transportados (ponderado/h) ao longo do período. E na margem esquerda verificou-se uniformidade da quantidade de troncos submersos transportados (ponderado/h) nos meses de dezembro e janeiro, discreto aumento no mês de fevereiro e redução abrupta no mês de março. Com isso, a Jirau Energia obteve informações sobre o funcionamento do antigo sistema de proteção Log Boom e sua disponibilidade operacional na UHE Jirau.

A agricultura brasileira enfrenta desafios significativos, como a dependência de fertilizantes químicos importados, que elevam custos e aumentam a vulnerabilidade a oscilações do mercado global, além de impactos ambientais como a contaminação de solos e águas. Nesse contexto, biofertilizantes e biochar surgem como soluções promissoras para promover sustentabilidade e reduzir esses impactos. Este estudo tem como objetivo analisar os benefícios econômicos e ambientais dessas tecnologias e propor políticas públicas que facilitem sua adoção. A metodologia combinou pesquisa exploratória e análise de patentes entre 2012 e 2023. Foram realizadas buscas bibliográficas em bases como Scielo e Google Acadêmico e consultas à plataforma Orbit Questel para mapear inovações tecnológicas e tendências relacionadas aos biofertilizantes e ao biochar. O período analisado abrangeu marcos importantes, como o Acordo de Paris e a criação do Programa Nacional de Bioinsumos. Os resultados destacam a redução de custos de produção com biofertilizantes locais e o papel do biochar no sequestro de carbono e na melhoria da qualidade do solo. Apesar disso, barreiras como infraestrutura inadequada, altos custos iniciais e lentidão no registro de patentes ainda limitam sua adoção em larga escala. O estudo conclui que o Brasil possui potencial para liderar globalmente a agricultura sustentável, desde que sejam implementadas políticas públicas integradas, incluindo incentivos financeiros, capacitação de agricultores e investimentos em pesquisa e desenvolvimento.

The North African (NA) region has recorded the highest average Carbon Dioxide (CO2) emissions in Africa and endures a growing rate in Mean Surface Temperature (MST) levels. Focusing on six NA countries: Algeria, Egypt, Libya, Morocco, Sudan, and Tunisia, this study examines the period from 1990 to 2020. A mathematical identity for anthropogenic CO2 emissions was derived using the Kaya identity, expressing individual countries through four drivers: population, GDP per capita, energy intensity, and carbon intensity. Panel Regression and Simple Linear Regression (SLR) analysis were further conducted to determine the regional and country-specific impact of CO2 emissions on MST. The key findings indicate a notable elevation in the four drivers among countries, resulting in over a 50% increase in CO2 emissions by 2020 compared to 1990. Regression results suggest that regional and local CO2 emissions significantly positively impact MST variations in the NA region. The study proposes customised local policies to address the drivers of CO2 emissions to mitigate the negative climatic consequences of rising CO2 levels.

These days lot of people spend long hours at a computer, so they face lot of health issues because of wrong sitting postures. Good posture is crucial for human well-being. A vision-based system is proposed to minimize the poor ergonomic practices among computer users. It can be installed in the corresponding user computer, and it runs with low computation burden. The proposed system is based on image comparison with a reference image. The reference image is an image, that the user utilizing their webcam or computer camera to capture themselves in the correct seated posture. Initially it has been a converted into grayscale and applied a Gaussian filter before store in the memory. After making the reference image, the proposed system is stared to capture user’s image at a free defined frequency. The captured user’s image is filtered and converted to a binary image using a predefined threshold. After that, two parallel processes are applied to same resultant image to identify the moment of left and right side and bending of forward and backward. The decision of both processes has been estimated by comparing the calculated black- to-white pixel ratio with a predefined threshold. The notification has been generated via a pop-up message on corresponding computer screen. To test the effectiveness, the proposed system has been implemented on a laptop computer in a Python environment with the support of OpenCV library. The test has been conducted of four different bad postures such as over leaning to the right angle, left angle, forward and backward postures with 150 attempts. The test results shows that it has high potential to identify the bad postures of computer uses.

The advancement of technology has transformed face-to-face communication by transferring interactions to virtual spaces such as Facebook, which are heavily used by undergraduates and might be negative to their mental health. The present quantitative study examined the predictive role of self-esteem in the problematic use of Facebook among undergraduates from universities in the Colombo District, Sri Lanka, and how gender moderates the connection. The study was conducted using a cross-sectional design, and an online survey with 372 undergraduates. Bergen’s Facebook addiction scale was used to measure the outcome variable, problematic usage of Facebook, while the Rosenberg self-esteem scale was used to test the predictor variable, self-esteem. In the analysis, gender was evaluated as a moderator variable. Data was analyzed using Simple linear regression and logistic regression analysis via SPSS and the Process Macro tool. Every phase of the research process included a careful integration of ethical considerations. Results show that higher self-esteem is associated with higher problematic Facebook utilization; however, this relationship is statistically significant (F (1, 370) = 26.230, p<.05), and it only accounts for a small percentage of the variance (R² =.066) in problematic use of Facebook among young individuals in Sri Lanka with no gender-based moderation. A variety of psychosocial factors significantly influence the self- esteem and problematic usage of Facebook of young individuals in Sri Lanka, and this effect is consistent for both gender categories, male and female. More research on the psychological and environmental problems linked to youth utilization of social media is desperately needed in Sri Lanka. Keywords: Self-esteem; Problematic Facebook Usage; Gender

Masonry units (i.e., bricks or earth blocks) made from agro and demolition waste have become popular day-by-day as a sustainable solution for environmental pollution. At the same time, such developments are also proposed as “adsorptive units” to treat heavy metals and organic dyes in industrial effluent streams. In this regard, a brick made from rice husk ash/cement/clay brick waste has been proposed to serve as both a masonry and adsorptive unit with a compressive strength of 3.61 MPa and 51% water absorption, which is suitable for non-load-bearing applications and can effectively adsorb common pollutants in wastewater (i.e. Pb(II), Hg(II), As(V)). However, the reported adsorption and mechanical properties have not been linked with the brick’s microstructure and surface characteristics. Thus, an in-depth understanding of the brick’s performance is unclear. In this regard, the present study utilizes Scanning Electron Microscopy (SEM) and Fourier Transformation Infrared Spectroscopy (FTIR) techniques to investigate the above. As per study outcomes, a pozzolanic reaction is evident in the brick through SEM and FTIR analyses. The phases portlandite, ettringite and calcium hydroxide phases are visible in the brick after 28 days of development, and the brick’s physical properties (water absorbency and compressive strength) can be correlated with C-S-H and C-A-H phases. Based on FTIR studies, it is evident that active groups (O-H and C-S-H) exist on the brick’s surface to assist the adsorption of Hg (II), Pb(II) and As(V) adsorbates.

Published: January 2025

Therapeutic psychology has been directed towards utilizing a synthesized approach of the Western and Eastern principles of health and healing with the emerging discipline of integrative care to adapt the potentials of holistic care relapse prevention, and promotion of a healthy lifestyle. Integrative care has introduced several therapeutic approaches and one of the prominent mind-body interventions was yoga therapy or therapeutic yoga. Yoga is a practice that has developed with the practice of physical posture (asana), breathing experience (pranayama), and meditation (dhyana), which provided the foundation for contemporary yoga therapy. Globally, both researchers and clinicians in mental health have utilized this approach to treat common mental health disorders and indicate significant outcomes related to the effective management of mental disorders such as depression, bipolar affective disorder, anxiety schizophrenia, and so on. In addition, yoga therapy was effective in the management of stress or the causes of mental disorders. Therefore, this study evidentially shows the contribution of yoga in the management of common mental disorders and the tool of prevention in future mental health care.

Amidst the socioeconomic advancements, the transgender community continues to endure marginalization, stigma, and discrimination. This persistent social reality underscores the urgent need to delve into the coping strategies employed by transgenders in navigating identity-related challenges and to assess the available psychosocial support systems. This study investigates perceptions of gender identity within the community and broader society, and the lived experiences of transgender individuals and their coping mechanisms. Employing a qualitative methodology, semi-structured interviews were conducted with ten transgender individuals, analyzing the data through thematic analysis. The data was obtained from a larger study that explored the Post-COVID Minority Distress and Resilience in Sri Lanka’s LGBTQIA+ Community. Findings illuminate the challenges faced, ranging from familial rejection to societal discrimination, including encounters with legal authorities. The perception of gender identity among transgender individuals is influenced by factors, including individual personality traits, available support networks, cultural context, awareness levels, and interactions within the community. While there has been a positive shift in societal attitudes in recent years, significant barriers persist, hindering full acceptance and integration of transgender identities. Despite the lack of formalized psychosocial support mechanisms, transgender individuals employ diverse coping strategies, including engagement with music, relaxation techniques, following religious practices, and withdrawing from social interactions to manage distress. In conclusion, while the existing community organizations offer vital support, the study findings underscore the need for comprehensive interventions spanning individual-level psychological support and systemic changes at the policy and legal levels. By addressing these multifaceted challenges and bolstering support structures, a more inclusive society can be fostered that affirms and supports the diverse identities within the transgender community.

Originated in England, English language is a West Germanic language that belongs to the Indo-European language family. From its introduction to the British Isles, the tremendous changes it experienced shaped and developed it into the current lingua franca. In order for English to become a dominant and significant language as it is now, it has gone through a development marked by signifi cant historical events and cultural exchanges. This study analyses Anglo Saxon English/Old English which is considered as the foundation of Englishes that are spoken and studied today. The key area that is analysed in this study includes the morphological features of Anglo Saxon English along with its comparison to the Modern English translation. Textual comparison is used for this purpose focusing on the historical poem: Caedmon’s Hymn. Furthermore, this research underscores how Old English morphology laid the groundwork for modern grammatical structures. The study reveals a gradual simplification of inflections over time, which led to a more streamlined syntax. Understanding these historical transformations enhances our appreciation of the language’s resilience and adaptability. The findings of this study emphasise the significance of historical linguistic evolution in shaping English, highlighting the enduring impact of its Anglo-Saxon roots on contemporary language.

The history of the English language identified two core varieties: British English and American English. However, World Englishes have gained prestige over the decades. English, therefore, has become the lingua franca in the world. As a result, Sri Lankan English has fascinatingly become a specific variety. The people of a particular region or a country adapt English in specific ways, which are visible in their regular activities such as at college, at supermarkets and at workplaces. Novel words can be found among several groups of people, which support the function of proper communication. Moreover, social media platforms spread varied English morphemes. The younger generation of Sri Lanka plays an innovative role in the process of word formation. Therefore, this research focuses on specific word formation processes in the Sri Lankan context among young adults. The objectives of this research are to recognize innovative word formation processes in English in the Sri Lankan context and to analyse the use of these processes which are commonly used among young adults in Sri Lanka. The data relevant to word formation processes were gathered by observing young adults’ speech on social media platforms and daily speech practices of the participants. The data collected were analyzed both quantitatively and qualitatively. Furthermore, data was gathered via a questionnaire distributed among the participants. Eleven different word formation processes which were identified are analyzed in this research and they are also categorized under the most-used formation processes and generally-used processes. The findings indicate that novel word formations in English are explicitly visible among young adults in the Sri Lankan context. It was also found that most of these formations occur unintentionally. This study is thus useful in identifying the key word formation processes prevalent in present Sri Lankan society and in understanding the future direction of Sri Lankan English.

This study assesses the monthly real wage rate of the public sector of Sri Lanka by elaborating a suitable time series model to identify the future trends associated with the real wage rates of Sri Lanka. The sample data set consists of monthly real wage rate data from January 2018 to March 2024 from the Central Bank of Sri Lanka (CBSL). The real wage rate has been calculated selecting 2016 as the base year. Suitable parsimonious models were identified through the patterns of the sample parti al autocorrelation function (PACF) and sample auto-correlation function (ACF) of the stationary series. Based on the indications such as Akaike information criterion (AIC), Schwarz Criterion (SC) and log likelihood an autoregressive integrated moving average (ARIMA) model of the type (0,1,2) was distinguished as the best fitted model. The residuals of the best fitted model were ascertained to be white noise. The model has been validated for the first three months of 2024. The Mean Absolute Percentage Error (MAPE) for the validation data is 9.59%.

Authors: Gao Xin , Zhang Jianxin
Published: January 2025

In this paper, greedy algorithm is used to optimize the planning of tourism routes based on multi-objective decision theory. The main goal of the research is to design the best travel route for foreign tourists by considering various factors such as time, cost and number of attractions. Firstly, this paper establishes a dataset including information of cities, attraction ratings, transportation time and cost through data integration and processing. Secondly, this paper used hierarchical analysis to evaluate 352 cities in multiple dimensions and identified the 50 cities that are most desirable to foreign tourists. Finally, combined with the greedy algorithm, this paper designed multiple optimization strategies under different constraints. The greedy algorithm used in the study can quickly provide tourist routes that meet the needs of tourists under multi-objective decision-making, and at the same time provides a new way of thinking for the planning of tourist routes.
Measurement and Analysis of Indoor Radon Concentration and its Influencing Factors in A University in Shanghai
Authors: Ma Xionghui
Published: January 2025

This study focuses on the dormitories of a university, where indoor radon concentrations and environmental parameters were measured using instruments such as the RAD7 detector from May to November 2024. The results show that the average indoor radon concentration was 26.83±22.30 Bq/m³, with a logarithmic distribution overall. Radon concentrations varied under different floor levels, times, seasons, weather conditions, and occupancy levels. For example, the first floor had the highest concentration, concentrations were higher at night and during the day, concentrations were relatively higher in winter, and were higher on sunny and cloudy days. Correlation analysis indicated significant associations between floor level, time, and season with radon concentrations. This study provides a basis for improving the dormitory environment in universities, though it has limitations such as the restricted measurement range and time. Future research could expand the scope and duration for further investigation.
Devletçilikten Özelleştirmeye Kastamonu’da Bir “Milli Fabrika”: Taşköprü Kendir Sanayi Müessesesi
Authors: Akın Yalçın Yeşim
Published: January 2025

Taşköprü Kendir Sanayi Müessesesi Sümerbank tarafından 1947 yılında Kastamonu’nun Taşköprü ilçesinde kurulmuştur. Devletçilik politikasının son dönemlerinde faaliyete geçen ve 1990'ların ikinci yarısına dek varlığını sürdüren müessesenin, hem yerel ölçekte katkıları hem Türkiye emek tarihi açısından kazandırdıkları önemlidir. Küçük ölçekli bir fabrika olan kuruluş, bölgenin iktisadi ve toplumsal dokusunu canlandırıcı niteliğiyle birlikte Türkiye’nin sermaye birikimindeki yeri açısından da önemlidir. Çalışma dâhilinde geçimlik tarımsal faaliyetle yaşamını sürdüren köylünün sanayi işçisine dönüşümü ile tarım sanayinin gelişimi ortaya koyulmuştur. Taşköprü Kendir Sanayi Müessesesinin somutluğunda, müessese çalışanlarının yaşamlarını ve üretim alanlarını dönüştürmelerinin öyküsünün emek tarihi yazınında hak ettiği yeri kazanması ve benzer araştırmalara yönelik ilginin artmasına katkı sağlaması amaçlanmıştır. Devletçilikten özelleştirmeye giden yolda belirleyici dinamiklerin etki ve sonuçları bu araştırmanın özünü oluşturmaktadır. Türkiye’nin kendir ihtiyacının % 40’ını karşılayan fabrikada iktisat politikalarının pratik karşılıkları ile yaşam koşullarındaki dönüşümlerin hem iktisadi hem toplumsal mercekten okunması çalışmanın zeminini belirlemektedir. 1980 sonrası özelleştirme dalgasından payını alan ve teknolojik gelişmelerden, yatırımlardan alıkonulan kurumun öyküsünde devletçilik ile başlayıp özelleştirmelere yüzünü dönen iktisat politikası arasındaki açı değerlendirilmektedir. Taşköprü örneği tarihe olduğu kadar içinde bulunduğumuz koşulları değerlendirmeye de ışık tutacaktır.
Türkiye’de Bölüşüm: En Büyük 1000 Sanayi Kuruluşu Üzerinden Bir Değerlendirme
Authors: Duvan Osman Berke
Published: January 2025

Emeğin gelirden aldığı pay tüm dünyada uzunca bir süredir gerilemektedir. 2008-2009’da küresel finansal kriz, 2020’de Covid-19 salgını emeğin payındaki gerilemeyi tüm ekonomilerde daha da görünür kılmıştır. Türkiye’de de benzer bir süreç yaşanırken, 2021’de ekonomi politikalarında yapılan değişiklikler ülke tarihinin en derin bölüşüm krizlerinden birine sebep olmuştur. Ekonomide yaşanan tıkanma ve kriz anları aynı zamanda bölüşüm ilişkilerinin emek ve sermaye ile sermayenin kendi içinde yeniden tanzim edildiği zamanlardır. Bu çalışma 1997-2023 döneminde en büyük 1000 sanayi kuruluşu üzerinden, Türkiye’de bölüşüm ilişkilerinde yaşanan değişimi ve bu değişim esnasında gerçekleşen kırılma anlarını analiz etmeyi amaçlamaktadır. Daha önce 1000 büyük sanayi kuruluşu üzerinden Türkiye’de böyle bir çalışma yapılmamıştır. Çalışma bu yönüyle ilktir. Elde edilen bulgulara göre; Türkiye’de nispi ücret dengesi büyük sanayi kuruluşlarında çalışanlar aleyhine gelişmektedir. Yine, 2001 krizinden sonra, bu kuruluşlarda çalışanların reel ücretleri emek verimliliğindeki artışlara intibak edememiştir. Son çeyrek yüzyılda, en büyük 500 firma başta olmak üzere, Türkiye’nin büyük sanayi kuruluşlarında emeğin katma değerden aldığı pay gerilemektedir. 2020-2022 döneminde yaşanan bölüşüm krizinde büyük sanayi kuruluşları, özellikle de ilk 500 firma, kâr marjlarını ve katma değerden aldıkları payı artırmış; buna karşın krizin yükü çalışanların omuzlarında kalmıştır.
Türkiye’de “Çalışma Ekonomisi ve Endüstri İlişkileri” Yayınlarının Gelişimi: Çalışma ve Toplum Dergisi Üzerinden Bir İnceleme
Authors: Cam Erdem , Yıldırım Engin
Published: January 2025

Türkiye’de çalışma ekonomisi ve endüstri ilişkileri alanında yayın yapan sınırlı sayıda uzmanlaşmış dergi bulunmaktadır. Bu dergilerde yapılan yayınlar hangi konuların önemli olduğu, sorun alanlarının tespiti ve bu bilim alanının hangi yöne evrimleştiği gibi sorulara yanıt bulmamızda bize ışık tutabilir. Bu makalede Çalışma Ekonomisi ve Endüstri İlişkileri konularında yayın yapan en önemli dergilerden biri olan Çalışma ve Toplum Dergisi’nin 2004-2023 yılları arasında yayımlanmış 80 sayısında toplam 686 makale incelenmiştir. Makaleler yıllık bazda inceleme altına alınmış ve makale konuları; “çalışma ekonomisi”, “endüstri ilişkileri”, “sosyal politika”, “iş ve sosyal güvenlik hukuku”, “insan kaynakları yönetimi” ve “diğer konular” başlıkları altında sınıflandırılmıştır. Çalışma ve Toplum dergisinde yayınlanan incelemelerden hareketle çalışma ekonomisi ve endüstri ilişkileri alanının geleneksel endüstri ilişkileri konularından sosyal politikanın başat olduğu daha geniş bir çalışma ilişkileri alanına doğru evrildiği görülmektedir.
ILO’nun İnsana Yakışır İş Hedefinin 2030 Sürdürülebilir Kalkınma Hedefi Bağlamında Değerlendirilmesi
Authors: Öktem Özgür Ayşenur
Published: January 2025

Birleşmiş Milletler (BM), 2030 yılına kadar sürdürülebilir kalkınmayı sağlamak amacıyla Sürdürülebilir Kalkınma Hedeflerini (SKH) kabul etmiştir. “Dünyamızı dönüştürmek” olarak adlandırılan bu hedefler, iddialı bir gündemin ana hatlarını çizmektedir. Bu hedefler arasında SKH 8, işgücü piyasasıyla ilgili olarak üretkenlik düzeyinin artırılması, 2030 yılına kadar herkes için tam ve üretken istihdamın sağlanması, insana yakışır işlerin oluşturulması gibi alt hedeflere sahiptir. Söz konusu hedef ayrıca, eşit işe eşit ücret, zorla çalıştırmanın ortadan kaldırılması, çocuk emeğine son verilmesi ve güvencesiz istihdam edilenler ve göçmen çalışanların çalışma haklarının korunmasını da içermektedir. BM'nin tüm üye ülkelerinde “insana yakışır iş” kavramı üzerinden ekonomik büyümeyi teşvik etme amacı doğrultusunda önemli bir uluslararası taahhüt bulunmaktadır. Ancak, insana yakışır iş ve ekonomik büyümeyi desteklemeye yönelik çabalara rağmen, bu hedeflere ulaşmada ciddi zorluklar devam etmektedir. Bu bağlamda, çalışmanın amacı, BM 2030 hedeflerinden SKH 8'in ulaşılabilirliğine yönelik mevcut durumu ortaya koymak ve işgücü piyasasına dair göstergeler ışığında tartışmaktır.
On the growth rate of partial quotients in Engel continued fractions
Authors: Song Kunkun , Li Zhihui , Shang Lei
Published: January 2025

Let $(b_n(x))_{n\geq 1}$ be the sequence of the partial quotients of the Engel continued fraction expansion of an irrational number $x\in(0,1)$. This paper is concerned with the Hausdorff dimension of some exceptional sets related to the growth rate of $(b_n(x))_{n\geq 1}$. As a main result, we obtain the Hausdorff dimension of the set $$E_{\inf}(\psi)=\{x\in[0,1):\liminf\limits_{n\to\infty}\frac{\log b_n(x)}{\psi(n)}=1\},$$ where $\psi:\mathbb{N}\rightarrow\mathbb{R}^+$ is a function satisfying $\psi(n)\to\infty$ as $n\to\infty$.
