Published: November 2024

IntroductionThe Dicranopteris dichotoma fern community plays vital roles in nutrient sequestration, succession regulation, and ecological threshold control. However, the mechanisms underlying the formation of the D. dichotoma–dominant community remain unclear.MethodsThis study established four different community types to investigate the effects of environmental factors on the formation of a D. dichotoma–dominant community.ResultsWe found that climate was the primary factor affecting the formation of patches dominated by D. dichotoma at the regional scale. Specifically, higher annual mean temperature and annual mean precipitation were associated with larger single-dominant-species patches of D. dichotoma. Understory light intensity was the major factor affecting the formation of the D. dichotoma community at the community scale. Light intensity ranging from 200 to 500 µmol·m⁻²·s⁻¹ was most conducive to the development of a large D. dichotoma community. Additionally, understory light intensity enhanced the importance value of D. dichotoma in the herb community by decreasing its biomass proportion of support modules and increasing its biomass proportion of photosynthetic and reproductive modules. Soil properties and D. dichotoma characteristics showed interactions with each other. Acidic red-yellow soil was most suitable for the formation of single-dominant-species patches of D. dichotoma, and the growth of D. dichotoma further decreased the soil pH. Soil total phosphorus content was identified as a limiting factor for formation of the D. dichotoma community.DiscussionIn summary, the formation of single-dominant-species patches of D. dichotoma is mainly influenced by a combination of climate, community, and soil.

BackgroundThere is persistent pressure on countries with a high burden of HIV infection to reach desired targets for HIV treatment outcomes. This has led to moving from the “one-size-fits-all” model to differentiated service delivery (DSD) models, which are meant to be more patient-centered and efficient but without compromising on the quality of patient care. However, for DSD models to be efficient, facilities should have indicators of HIV services available and ready to provide the DSD models. We aimed to assess the availability of HIV service indicators and the readiness of facilities to provide DSD models for HIV treatment in selected public health facilities in Zambia.MethodsWe conducted a nationwide cross-sectional survey among public health facilities in Zambia that provide antiretroviral therapy (ART) services. We used an interviewer-administered questionnaire based on a World Health Organization (WHO) Service Availability Readiness Assessment (SARA) tool to assess the availability of HIV service indicators and the readiness of facilities to implement DSD models for HIV treatment. Availability and readiness were considered latent constructs, and therefore, we used structural equation modeling (SEM) to determine the correlations between them and their respective indicators.ResultsOf 60 public health ART facilities, the overall availability of HIV service indicators was 80.0% (48/60), and readiness to provide the DSD models was 81.7% (48/60). However, only 48 and 39% of the facilities had all indicators of availability and readiness, respectively. Retention in care for HIV multidisciplinary teams was more likely to occur in urban areas than in rural areas. SEM showed that the standardized estimate between availability and readiness was significantly and positively correlated (r = 0.73, p &lt; 0.0001). In addition, both availability and readiness were significantly and positively correlated with most of their respective indicators.ConclusionAlthough most facilities had available HIV service indicators and were ready to provide DSD models, most facilities did not have all indicators of availability and readiness. In addition, there were differences between rural and urban facilities in some indicators. There is a need for persistent and heightened efforts meant to implement DSD in HIV treatment, especially in rural areas to accelerate reaching the desired HIV treatment outcomes.

Leishmania spp. commonly infects phagocytic cells of the immune system, particularly macrophages, employing various immune evasion strategies that enable their survival by altering the intracellular environment. In mammals, these parasites establish persistent infections by modulating gene expression in macrophages, thus interfering with immune signaling and response pathways, ultimately creating a favorable environment for the parasite’s survival and reproduction. In this study, our objective was to use data mining and subsequent filtering techniques to identify the genes that play a crucial role in the infection process of Leishmania spp. We aimed to pinpoint genes that have the potential to influence the progression of Leishmania infection. To achieve this, we exploited prior, curated knowledge from major databases and constructed 16 datasets of human molecular information consisting of coding genes and corresponding proteins. We obtained over 400 proteins, identifying approximately 200 genes. The proteins coded by these genes were subsequently used to build a network of protein–protein interactions, which enabled the identification of key players; we named this set Predicted Genes. Then, we selected approximately 10% of Predicted Genes for biological validation. THP-1 cells, a line of human macrophages, were infected with Leishmania major in vitro for the validation process. We observed that L. major has the capacity to impact crucial genes involved in the immune response, resulting in macrophage inactivation and creating a conducive environment for the survival of Leishmania parasites.
New Results on Graph Matching from Degree-Preserving Growth

Published: November 2024

The recently introduced model in S. R. Kharel et al.’s study [Degree-preserving network growth. Nature Physics 2022, 18, 100–106] uses matchings to insert new vertices of prescribed degrees into the current graph of an ever-growing graph sequence. The process depends both on the size of the largest available matching, which is the focus of this paper, as well as on the actual choice of the matching. Here, we first show that the question of whether a graphic degree sequence, extended with a new degree 2δ, remains graphic is equivalent to the existence of a realization of the original degree sequence with a matching of size δ. Secondly, we present lower bounds for the size of the maximum matchings in any realization of the degree sequence. We then study the bounds on the size of maximal matchings in some realizations of the sequence, known as the potential matching number. We also estimate the minimum size of both maximal and maximum matchings, as determined by the degree sequence, independently of graphical realizations. Along this line we answer a question raised by T. Biedl et al.: Tight bounds on maximal and maximum matchings. Discrete Mathematics 2004, 285, 7–15.

Published: November 2024

This paper investigates the optimization of tensile strength, tensile strength per unit weight, and tensile strength per unit time of polyethylene terephthalate glycol (PETG) material in fused deposition modeling (FDM) technology using the Taguchi method and analysis of variance (ANOVA). Unlike previous studies that typically focused on optimizing a single mechanical property, our research offers a multi-dimensional evaluation by simultaneously optimizing three critical quality characteristics: tensile strength, tensile strength per unit weight, and tensile strength per unit time. This comprehensive approach provides a broader perspective on both the mechanical performance and production efficiency, contributing new insights into the optimization of PETG in FDM. The Taguchi method (L16 45) was designed and executed, with the layer height, infill density, print temperature, print speed, and infill line direction as the control factors. Sixteen tensile tests were conducted, and ANOVA was employed to identify the main influencing factors for each quality characteristic. For the tensile strength, the infill density was found to have the greatest impact (48.45%), while the print temperature had the least impact (0.78%). The optimal parameter combination reduced the quality loss to 31.28% and standard deviation to 55.93%. For tensile strength per unit weight, the infill line direction had the greatest impact (87.22%), whereas the print temperature had the least impact (0.77%). The optimal parameter combination reduced the quality loss to 54.09% and standard deviation to 73.54%. Regarding the tensile strength per unit time, the layer height had the greatest impact (82.12%), while the print temperature had the least impact (0.08%). The optimal parameter combination reduced the quality loss to 10.81% and standard deviation to 32.87%.

Tujuan dari penelitian ini adalah ditemukannya konsep serta strategi pemberdayaan masyarakat inklusi terkait anak penyandang disabilitas serta ditemukannya sejauh mana bentuk penegakan hukum dalam pemenuhan hak-hak anak penyandang disabilitas. Penelitian ini dilakukan secara deskriptif analitis, yaitu memberikan fakta yang ada, baik berupa data sekunder bahan pemerintahan dan bahan hukum primer. Berpedoman dari peraturan tersebut maka Dinas Sosial Kabupaten Bandung Barat mempunyai peran yang penting yaitu memberikan pelayanan di bidang sosial dan menjadi solusi bagi permasalahan pada masyarakat. Permasalahan yang ada di masyarakat cukup beragam khususnya masalah tentang anak yang mana permasalahan ini menjadi perhatian yang penting bagi pemerintah karena kasus yang terjadi pada anak mengalami peningkatan yang signifikan. Masalah pada anak ini beragam salah satunya yakni permasalahan pada anak yang menyandang disabilitas. Secara yuridis normatif Pemerintah Kabupaten Bandung Barat sudah memiliki Peraturan Daerah Kabupaten Bandung Barat Nomor 2 Tahun 2022 tentang Penghormatan, Perlindungan, dan Pemenuhan Hak Disabilitas. Kendala penegakan hukum dalam pemenuhan hak-hak anak penyandang disabilitas dapat dilihat berdasarkan faktor sarana dan fasilitas pendukung, serta budaya hukum masyarakat. Sosialisasi dan edukasi sebaiknya lebih dioptimalkan kembali oleh Dinas Sosial dan para stakeholder lainnya karena masih minimnya pengetahuan, kondisi, dan partisipasi masyarakat tentang disabilitas, serta penegakan hukum tidak hanya melibatkan institusi akan tetapi juga masyarakat.

This research presents an analysis of language politeness in interactions between students and lecturers on WhatsApp group. With the increasing integration of digital platforms in educational settings, understanding the dynamics of language use and politeness in these contexts becomes crucial. The study aims to investigate the strategies employed by students and lecturers to convey politeness and maintain positive interactions within a virtual learning environment. The research adopts a qualitative approach, utilizing discourse analysis to examine messages exchanged on WhatsApp group among students and lecturers. The data collection involved capturing and archiving conversations from WhatsApp group in English Syntax course in 2021/2022 academic year of English Department in Universitas Komputer Indonesia (Unikom). The data are analyzed using Leech’s politeness theory. According to Leech the politeness principles are divided into six, namely the tact maxim, generosity maxim, approbation maxim, modesty maxim, agreement maxim, and sympathy maxim. The results show that the percentage of conformity regarding compliance and violation of maxims with the result being 100% conform, so that politeness in language interactions between students and lecturers in WhatsApp media in the course was stated to be very polite. The findings indicate that both students and lecturers employ various politeness strategies to foster positive communication. These strategies include the use of indirect speech acts, mitigating language, politeness markers, and positive politeness strategies such as expressing gratitude and offering support. Furthermore, the analysis reveals the influence of power dynamics on language politeness. Lecturers were found to engage in a more authoritative discourse, while students often adopted deferential and respectful language. However, instances of assertiveness from students were also observed, challenging traditional power differentials and promoting a more egalitarian communication style. The implications of this research shed light on the importance of fostering respectful and polite communication within virtual learning environments. The findings can inform educators and students on effective language use to maintain positive interactions and create inclusive educational spaces. Furthermore, the study contributes to the existing literature on digital communication and politeness strategies, adding valuable insights into the specific context of WhatsApp group interactions in educational settings.

Published: November 2024

Graffiti merupakan seni yang saat ini mulai digemari oleh anak – anak muda di ruang publik, sebagai karya seni jalanan, graffiti banyak menghiasi tembok – tembok pinggir jalan, dan dengan banyaknya anak muda yang memiliki minat terhadap karya seni ini, mereka kemudian membuat kelompok – kelompok. Timbulnya banyak kelompok membuat adanya pergesekan kelompok satu dengan yang lainnya dalam memperebutkan ruang publik untuk membangun eksistensi kelompok mereka masing – masing. Perseteruan antar kelompok kemudian menjadi hal yang tidak terhindarkan bagi kelompok graffiti dalam upaya mereka membangun eksistensi kelompok satu sama lain. Penelitian ini membahas tentang bagaimana graffiti digunakan sebagai alat dalam membangun eksistensi kelompok dari sudut pandang pegiat graffiti dalam suatu kelompok yang pernah mengalami kasus penimpaan karya graffiti mereka dengan karya kelompok lain. Metode yang digunakan dalam penelitian ini menggunakan metode etnometodologi dengan pendekatan kualitatif yang bersifat deskriptif. Pengumpulan data penelitian ini menggunakan teknik wawancara dengan ikut serta dalam kegiatan kelompok graffiti turun ke jalan membuat karya di jalanan. Hasil penelitian ini menunjukkan bahwa dalam membangun eksistensi penimpaan karya satu kelompok menjadi salah satu bentuk kelompok tersebut membangun eksistensi mereka namun dampaknya menghadirkan perselisihan antar kelompok yang memiliki karya asli dengan kelompok yang menimpa karya tersebut.
