"Because of HIV, It Opened My Mind": Intersectional Stigma Experiences Among Filipino Gay and Bisexual Men Living With HIV.

Previous work has demonstrated that gay, bisexual men, and other men who have sex with men (GBM) living with HIV are likely to experience intersectional stigma. However, mainstream systems often fail to recognize how power and privilege shape this experience. Such a complex psychological phenomenon requires an in-depth reflective inquiry that acknowledges individuals as experts in their own experiences. To explicate this matter, this study aimed to develop an understanding of how intersectional stigma impacts the experiences of GBM living with HIV and to illuminate how contexts (un)fuel inequities. The semi-structured interviews with five Filipino GBM living with HIV were analyzed using interpretative phenomenological analysis (IPA). Exploration of their accounts elucidated how cultural elements fueled power dynamics and privilege, which in turn shaped intersectional stigma and their experiences. Narratives accentuated how Filipino GBM living with HIV situate themselves from victims to agents of change who empower and liberate others in the community. Insights from this study underscore the critical role of collective actions in bridging gaps in inequities and guiding the improvement of policies and interventions that are well-suited to the context and culturally appropriate for people living with HIV and other multiply marginalized populations.

Design concept of intelligent integrated control system for neutral beam injection

Abstract Due to the specificity of neutral beam injection (NBI) system, the control of its actual physical system is achieved by the integrated control system (ICS). The current NBI ICS adopts a distributed design structure to balance the system load, which is also the mainstream system design and architecture model of ICS around the world. However, from a practical point of view, the distributed system architecture is not perfect. In the long run, upgrading the system intelligence and automation capabilities is an inevitable choice for the future, so it is necessary to explore ways to transform and upgrade the ICS. At present, Internet of Things (IoT), as an important part of the new generation information technology, can realize the control of everything through data exchange. This is because on the one hand, IoT has wide compatibility and powerful scenario-based capabilities, it not only has the advantages and characteristics of distributed design, but also can pull the NBI subsystems into the same level scenario and lay the foundation for the further construction of digital NBI; on the other hand, the intervention of artificial intelligence makes IoT have some new typical characteristics such as intelligent sensing, ubiquitous connectivity, precise control, digital modeling, real-time analysis and iterative optimization, which is enough to pull the current NBI ICS into a new intelligent control era. Finally, it is worth mentioning that due to its inherent design structure and functional characteristics, ICS tends to be broadly generic, so it is not exclusively used for NBI operation in nuclear fusion, and it can provide some insight into other application areas.

Enriching systems practice with African perspectives

AbstractThis paper follows an autoethnographic approach that seeks to give a practitioner's reflection by exploring the intersection between African philosophies, particularly the concepts of Ubuntu and Ukama, and the practice of systems thinking. It raises concern about the absence of an African perspective in the discourse on mainstream systems thinking approaches. It argues that African philosophies, with their emphasis on relationality, community and humanness, can contribute to and enrich the discourse on developing systems thinking approaches. The main author's positionality, including his struggles with his identity as an African, his personal experiences growing up in a rural African village and being exposed to traditional African storytelling and community‐based practices, is used to illustrate the connections between African philosophies and systems thinking. As an example of this linkage and how an African perspective can enrich the practice of systems thinking, the paper applies an African worldview to Critical Systems Heuristics.

Real-Time Estimation of Tree Position, Tree Height, and Tree Diameter at Breast Height Point, Using Smartphones Based on Monocular SLAM

Precisely estimating the position, diameter at breast height (DBH), and height of trees is essential in forest resource inventory. Augmented reality (AR)-based devices help overcome the issue of inconsistent global point cloud data under thick forest canopies with insufficient Global Navigation Satellite System (GNSS) coverage. Although monocular simultaneous localization and mapping (SLAM) is one of the current mainstream systems, there is still no monocular SLAM solution for forest resource inventories, particularly for the precise measurement of inclined trees. We developed a forest plot survey system based on monocular SLAM that utilizes array cameras and Inertial Measurement Unit (IMU) sensors provided by smartphones, combined with augmented reality technology, to achieve a real-time estimation of the position, DBH, and height of trees within forest plots. Our results from the tested plots showed that the tree position estimation is unbiased, with an RMSE of 0.12 m and 0.11 m in the x-axis and y-axis directions, respectively; the DBH estimation bias is −0.17 cm (−0.65%), with an RMSE of 0.83 cm (3.59%), while the height estimation bias is −0.1 m (−0.95%), with an RMSE of 0.99 m (5.38%). This study will be useful in designing an algorithm to estimate the DBH and position of inclined trees using point clouds constrained by sectional planes at the breast height of the trunk, developing an algorithm to estimate the height of inclined trees utilizing the relationship between rays and plane positions, and providing observers with visual measurement results using augmented reality technology, allowing them to judge the accuracy of the estimates intuitively. Clearly, this system has significant potential applications in forest resource management and ecological research.

Chronic Kidney Disease in Light of Ayurveda: A Literary Review on Vataj Pandu

In recent years, chronic kidney disease (CKD) has become a centre of attraction for researchers all over the world, due to increasing incidence. However, delayed diagnosis and lack of proper management has made it one of the leading causes of death worldwide. In the earlier phase of the disease, relief to the patients can be provided based on chief complaints. But as the disease progresses, only dialysis and kidney transplants remain the line of treatment according to the mainstream system of medicine, thus leading to a large number of side effects and ultimately decreasing the life expectancy. In Ayurveda, CKD is not mentioned in the Samhita directly, but it can be correlated with Vataj pandu according to similarities in some of the symptoms and causes of these two diseases as mentioned in ancient literature. We can also look out for the Nidaan and Samprapti according to the history given by the patient and evaluate the Dosh, Dushya, and the Srotas involved, and then devise a line of treatment according to the patient's Bala, Prakriti, Agni and Oja. In this article, we're going to talk about an aspect of CKD that can be used as a part of management to improve the quality of life and give hope to all the patients suffering from this disease.

Deconstructing gendered approaches in ‘single-sex’ flexi schools: two Australian case studies

In Australia coeducation dominates government schooling, with single-sex institutions usually being the preserve of selective government schools and private, often elite, institutions. For marginalised young people who ‘drop out’ or are forced to leave the coeducational mainstream system, flexible and/or non-traditional schools provide alternative pathways. Such schools are primarily coeducational. This paper draws upon data from two flexible/non-traditional schools in Australia that attempted to address the issues of educational disengagement via the provision of single-sex schooling: Fernvale Education Centre and Lorem School. The data are insightful with regard to these two very different gender and education paradigms and to their associated discourses about masculinity and femininity. The paper will identify the ways in which these schools both reproduce and challenge dominant constructions of gender within the context of responding to disenfranchised/disengaged young people.

Continuous-variable quantum key distribution system: Past, present, and future

Quantum key distribution provides secure keys with information-theoretic security ensured by the principle of quantum mechanics. The continuous-variable version of quantum key distribution using coherent states offers the advantages of its compatibility with telecom industry, e.g., using commercial laser and homodyne detector, is now going through a booming period. In this review article, we describe the principle of continuous-variable quantum key distribution system; focus on protocols based on coherent states, whose systems are gradually moving from proof-of-principle lab demonstrations to in-field implementations and technological prototypes. We start by reviewing the theoretical protocols and the current security status of these protocols. Then, we discuss the system structure, the key module, and the mainstream system implementations. The advanced progresses for future applications are discussed, including the digital techniques, system on chip, and point-to-multipoint system. Finally, we discuss the practical security of the system and conclude with promising perspectives in this research field.

A Distributed System Fault Diagnosis System based on Machine Learning

Now days distributed system becomes the mainstream system of information storage and processing. Compared with traditional systems, distributed systems are larger and more complex.However, the average probability of failure is higher and the difficulty, complexity of operation and maintenance are greatly increased. Therefore, it is necessary to use efficient methods to diagnose the system. Our aim is to use the trained model to diagnose the fault data of the distributed system, so we can obtain as high diagnostic accuracy as possible, and create a web side for users to use. The technique we proposed uses the integrated learning approach of Stacking to model the superposition of the raw data. To realize this, we trained with a dataset of 10,000 pieces of data and assessed accuracy every once in a while. Our best training results are about 80.69% accurate and can be used on the web side. By training data sets and analyzing distributed system faults with Stacking technology, a model with a test accuracy of 80.69% was obtained. Through this model and the web platform we built, the fault of distributed system can be diagnosed, and the diagnosis results are better than other models.

Facilitators for inclusive education: rethinking schools from the experience of young people with intellectual disabilities in Spain

Although compulsory education is a reality for students between the ages of 6 and 16 in Spain, the search for a single quality system for all and success for all continues to be a concern for the Spanish education system and an ongoing issue after successive educational reforms. The aim of this article is to present the facilitators for educational inclusion identified by 30 young people with intellectual disabilities between the ages of 19 and 30 in Spain. Using a biographical-narrative methodology, these young people review and reflect on their educational trajectories, from primary school to university. The participants identified factors related to the teaching staff, pupils, and the curriculum which helped them in their learning and contributed to their feeling of being part of the educational institution, especially in the very last years of their educational training. The facilitators outlined above could be key to rethinking some decision-making in schools. Points of interest Many students with intellectual disabilities in Spain are in segregated schools during the compulsory education level. This article analyses the facilitators that 30 young people with intellectual disabilities identify in their educative experiences, from primary school to university education, using a biographical-narrative methodology. All the participants began their educational experience in the mainstream system, but most of them were sent to special schools during the secondary education. The participants identify facilitators that have helped them to learn and participate in their educational pathway which is related to teachers, curriculum, and peers.

Model and algorithm analysis of MPC control in aerospace engineering

With the continuous development of time and technology, the control system has thus evolved in the direction of great complexity. In the field of path control, once control algorithms cannot absolutely meet the requirements of all people, so this paper introduces an alternative algorithm-MPC. This article focuses on the development of MPC from when it is invented and its application in aerospace today with specified examples, and then lists and analyses the mainstream MPC algorithms, namely LTI, LTV, LPV, PWA and nonlinear systems. Article below also illustrates the derivation of sample of non-parametric model-based algorithms (Dynamic matrix control) and parametric model-based algorithms (Generalized Predictive Control) and the elaboration of mainstream systems and their applications in the form of an overview. Eventually gives a conclusion to the current situation of MPC and relationships among various algorithms. Note that this article is mainly aimed at scholars who are new to MPC algorithms.

한국 대중음악에서의 B급 문화 분석 연구

The purpose of this paper is to study B-class culture in Korean popular music. B-class identity as a subculture was examined, observing the changes in B-class music since the 2000s, and cultural diversity was discussed. Following the literature review, Psy, Norazo, and UV were selected as research subjects. The external items of capital, popularity, and intentionality and the internal items of language, content, format, behavior, and image characteristics were analyzed deductively through NVivo 14. As a result, Psy's music carried B-class features in terms of language, behavior, and image, and Norazo and UV's music had them in all internal aspects. Those meanings have all been transferred to a reconceptualized B-class. They were subordinated to large capital or the mainstream system, and the consumer base expanded from the minority to the majority. Moreover, resistance has weakened and was replaced by interest. The B-class mainstreaming passed through a latent and transitional period in the 2000s and settled on one side of the popular culture in the 2010s, facing the authenticity issue. Opinions on diversifying music culture were presented, with the claims for recovery of the rights of musical cultural subjects and resolution of the imbalance in music culture.

How to Provide Nitrite Robustly for Anaerobic Ammonium Oxidation in Mainstream Nitrogen Removal.

Innovation in decarbonizing wastewater treatment is urgent in response to global climate change. The practical implementation of anaerobic ammonium oxidation (anammox) treating domestic wastewater is the key to reconciling carbon-neutral management of wastewater treatment with sustainable development. Nitrite availability is the prerequisite of the anammox reaction, but how to achieve robust nitrite supply and accumulation for mainstream systems remains elusive. This work presents a state-of-the-art review on the recent advances in nitrite supply for mainstream anammox, paying special attention to available pathways (forward-going (from ammonium to nitrite) and backward-going (from nitrate to nitrite)), key controlling strategies, and physiological and ecological characteristics of functional microorganisms involved in nitrite supply. First, we comprehensively assessed the mainstream nitrite-oxidizing bacteria control methods, outlining that these technologies are transitioning to technologies possessing multiple selective pressures (such as intermittent aeration and membrane-aerated biological reactor), integrating side stream treatment (such as free ammonia/free nitrous acid suppression in recirculated sludge treatment), and maintaining high activity of ammonia-oxidizing bacteria and anammox bacteria for competing oxygen and nitrite with nitrite-oxidizing bacteria. We then highlight emerging strategies of nitrite supply, including the nitrite production driven by novel ammonia-oxidizing microbes (ammonia-oxidizing archaea and complete ammonia oxidation bacteria) and nitrate reduction pathways (partial denitrification and nitrate-dependent anaerobic methane oxidation). The resources requirement of different mainstream nitrite supply pathways is analyzed, and a hybrid nitrite supply pathway by combining partial nitrification and nitrate reduction is encouraged. Moreover, data-driven modeling of a mainstream nitrite supply process as well as proactive microbiome management is proposed in the hope of achieving mainstream nitrite supply in practical application. Finally, the existing challenges and further perspectives are highlighted, i.e., investigation of nitrite-supplying bacteria, the scaling-up of hybrid nitrite supply technologies from laboratory to practical implementation under real conditions, and the data-driven management for the stable performance of mainstream nitrite supply. The fundamental insights in this review aim to inspire and advance our understanding about how to provide nitrite robustly for mainstream anammox and shed light on important obstacles warranting further settlement.

Indian Tribal Narratives: Retracing History and Culture

Culture, a term with abstract meanings, can highlight Eastern culture's perceived spirituality over Western culture. Indian culture, with a 5000-year history, is captivating, blending adaptability and indigenous values. This paper focuses on ethnic life representation in Indian literature, especially through tribal communities. Novels by tribal authors serve as a platform, analyzing ethnicity in socio-cultural and historical contexts. Literature offers insight into lives, experiences, and teachings, shedding light on marginalized indigenous populations seeking recognition. Emerging literature lets indigenous ethnicities represent dynamic cultures and reclaim hidden histories. The paper's primary objective is to discuss the socio-political and cultural significance of tribal literature. It accomplishes this by analyzing tribal narratives from Kerala and Arunachal Pradesh, featuring works by authors like Narayan and Mamang Dai. These narratives delve into tribal identity and their struggles within the mainstream system. The paper provides an insightful examination of tribal life and society in these regions, as portrayed by these authors.

Research on Fault Detection for Microservices Based on Log Information and Social Network Mechanism Using BiLSTM-DCNN Model

The microservice architecture breaks through the traditional cluster architecture mode based on virtual machines and uses containers as carriers to interact through lightweight communication mechanisms to reduce system coupling and provide more flexible system service support. With the expansion of the system scale, a large number of system logs with complex structures and chaotic relationships are generated. How to accurately analyze the system logs and make efficient fault prediction is particularly important for building a safe and reliable system. By studying neural network technology, this paper proposes an Attention-Based Bidirectional Long Short-Term Memory Network (Bi-LSTM). Combined with the dual channel convolutional neural network model (DCNN), it uses the attention mechanism to explore the differences between dimensional features, realizes multi-dimensional feature fusion, and establishes a BiLSTM-DCNN deep learning model that integrates the attention mechanism. From the perspective of social network analysis, a data preprocessing method is proposed to process fault redundant data and improve the accuracy of fault prediction under Microservices. Compare BiLSTM-DCNN with the mainstream system log analysis machine learning models SVM, CNN and Bi-LSTM, and explore the advantages of BiLSTM-DCNN in processing microservice system log text. The model is applied to simulation data and HDFS data set for experimental comparison, which proves the good generalization ability and universality of BiLSTM-DCNN.

A Study of Subculture Based on Online Communication from the Perspective of Carnival Theory: Taking Hip-Hop Culture as an Example

As a kind of subculture that is relatively popular among young people, hip-hop culture has been developing well in the past few years with the power of internet communication. Hip-hop culture includes street dance, rap, DJ and graffiti, and has a very rebellious spirit that advocates a free and equal relationship. As for China, hip-hop culture, as an imported product, was once excluded from the mainstream system and had been growing wildly "underground" for a long time. However, in recent years, along with the broadcast of some variety shows, hip-hop culture has been presented in the discourse system of mass media based on online communication, which has attracted widespread attention. The essay includes four parts. The first part starts from the respective concepts of hip-hop culture, subculture, and rave concept, and explains their definition and the process of development respectively. The second part explains the connotation and development of hip-hop culture and subculture from the perspective of rave theory. The third part describes how the online medium has influenced cultural communication. The last part describes the process of localization and transformation of hip-hop culture in China and its current development.

Feasibility of a return-sludge nursery concept for mainstream anammox biostimulation: Creating optimal conditions for anammox to recover and grow in a parallel tank

To overcome limiting anammox activity under sewage treatment conditions, a return-sludge nursery concept is proposed. This concept involves blending sludge reject water treated with partial nitritation with mainstream effluent to increase the temperature, N levels, and electrical conductivity (EC) of the anammox nursery reactor, which sludge periodically passes through the return sludge line of the mainstream system. Various nursery frequencies were tested in two 2.5 L reactors, including 0.5–2 days of nursery treatment per 3.5–14 days of the total operation. Bioreactor experiments showed that nursery increased nitrogen removal rates during mainstream operation by 33–38%. The increased anammox activity can be partly (35–60%) explained by higher temperatures. Elevated EC, higher nitrogen concentrations, and a putative synergy and/or unknown factor were responsible for 15–16%, 12–14%, and 10–36%, respectively. A relatively stable microbial community was observed, dominated by a “Candidatus Brocadia” member. This new concept boosted activity and sludge growth, which may facilitate mainstream anammox implementations based on partial nitritation/anammox or partial nitrification/denitratation/anammox.

Does desegregation matter? A comparative study of school‐based social capital for university‐bound minority students in segregated and desegregated school contexts of Hong Kong

AbstractDespite national policies, de facto school segregation for racial/ethnic minority students in the West and East has continued to deepen. In Hong Kong, the segregated school system was abolished in 2013, while from 2004 reformed School Places Allocation Systems encouraged minority students to choose mainstream primary and secondary schools. However, de facto ethnicity‐based school segregation continues to prevail. Most minority students in the mainstream system are stuck in low‐status schools where they face discrimination and institutional exclusion. This has led many of them to retreat to a limited number of schools that have traditionally catered for minority communities. Such segregation calls forth scholarly attention to the paradoxical correlation between the physical mixing of diverse students and equality of educational opportunity, especially equal access to post‐secondary education (PSE)—a key for minority youth to function in the competitive labour market. This study employed the theory of school‐based social capital (SBSC) and compared the ways in which PSE‐relevant institutional resources and support were rationalised and enacted by staff in de facto segregated and desegregated school contexts. Case studies of two secondary schools lead us to argue that desegregation is only effective when institutional structure, culture and agents empower minority students through access to instrumental resources and support for the pursuit of PSE. The findings confound the desegregation policy and call for structural/institutional interventions to ensure instrumental SBSC is accessible to PSE‐bound minority students in all schools, and thus increase the effectiveness of school desegregation.

Impact of instrumentation reliability on mainstream suspended Partial denitrification anammox (PdNA).

This study successfully revealed the importance of probe reliability and sensitivity with ion sensitive electrode (ISE) probes on achieving high partial denitrification (PdN) efficiency; and decreasing carbon overdosing events that cause the decline of microbial populations and performance of partial denitrification-anammox (PdNA). In a mainstream integrated hybrid granule-floc system, an average PdN efficiency of 76% was achieved with acetate as the carbon source. Thauera was identified as the dominant PdN species; Its presence in the system was analogous to instrumentation reliability and PdN selection and wasn't a consequence of bioaugmentation. Up to 27-121 mg TIN/L/d, an equivalent of 18 - 48% of the overall TIN removed, was achieved through the PdNA pathway. Candidatus Brocadia was the main anoxic ammonium oxidizing bacteria (AnAOB) species that was seeded from sidestream, and enriched and retained in the mainstream system with observed growth rates of 0.04 - 0.13 d-1 . Moreover, there was no direct negative impact of methanol's use for post-polishing on AnAOB activity and growth.

Indigenous institutions and local government in the Torres Strait

AbstractThe relationships between local governments and Indigenous institutions in Australia are unstudied, despite both being oriented to the local level. Related research focuses on the performance of Indigenous local governments, Indigenous forms of governance and its relation to local government, relations between local governments and Indigenous communities, and the intercultural dynamics of Indigenous and Western governance frameworks in local governments. This article presents the findings of a study that examines relations between local governments and Indigenous institutions in the Torres Strait, a relationship that is framed by s. 9(3) of the Local Government Act 2009 (Qld) (LGA) that allows local governments to ‘take account of Aboriginal tradition and Island custom’. A framework adapted from health‐related studies, consisting of three alternative policy approaches—mainstreaming, indigenisation, and hybridisation—is used in this study to characterise relationships between local governments and Indigenous institutions. Kinship and country, two important Indigenous institutions, are marginalised in Queensland's mainstream system of local government, which in turn creates obstacles for Aboriginal and Torres Strait Islander people from participating and engaging in local government processes.Points for practitioners Government that does not recognise the institutions which are fundamental to how Indigenous people govern will marginalise them from power. Indigenous institutions are legitimate actors whose voice must be considered within mainstreaming discussions. Representation within indigenous institutions influences local government relations.

Creating and sustaining democratic spaces in education

Abstract This article explores the context for the accompanying suite of papers on creating and sustaining democratic spaces in education. Prompted by the centenary of Summerhill, the internationally famous democratic school founded in Suffolk, England, in 1921, by A.S. Neill, this collection of papers explores and broadens out the central questions at the heart of experiments in democratic education. We suggest that, at a time of distrust in and questioning of the central institutions of democratic government, and in the wake of challenges to the mainstream system of state schooling, these questions are more relevant than ever. We argue that detailed attention to the everyday practice of creating democratic spaces in a variety of educational and social contexts can highlight the myriad ways in which educators, students, families and communities can keep democratic values and principles alive, thereby enriching our discussions about the meaning and value of democratic education.
