Hypergraph Convolution on Nodes-Hyperedges Network for Semi-Supervised Node Classification

Hypergraphs have shown great power in representing high-order relations among entities, and lots of hypergraph-based deep learning methods have been proposed to learn informative data representations for the node classification problem. However, most of these deep learning approaches do not take full consideration of either the hyperedge information or the original relationships among nodes and hyperedges. In this article, we present a simple yet effective semi-supervised node classification method named Hypergraph Convolution on Nodes-Hyperedges network, which performs filtering on both nodes and hyperedges as well as recovers the original hypergraph with the least information loss. Instead of only reducing the cross-entropy loss over the labeled samples as most previous approaches do, we additionally consider the hypergraph reconstruction loss as prior information to improve prediction accuracy. As a result, by taking both the cross-entropy loss on the labeled samples and the hypergraph reconstruction loss into consideration, we are able to achieve discriminative latent data representations for training a classifier. We perform extensive experiments on the semi-supervised node classification problem and compare the proposed method with state-of-the-art algorithms. The promising results demonstrate the effectiveness of the proposed method.

Achieving Reconciliation between Privacy Preservation and Auditability in Zero-trust Cloud Storage using Intel SGX

Cloud storage allows for saving files at an off-site location that is accessible through the public internet. However, cloud storage suffers from a lack of trust since employees have physical and electronic access to almost all of the data, and zero-trust security is thus essential. This paper proposes an SGX-based file hosting scheme that gives full consideration to both privacy preservation and auditability to address the aforementioned concerns. We designed a secure key exchange protocol consisting of two phases: a key generation phase and a key verification phase. Theoretical analysis and experiments indicate that the protocol can resist man in-the-middle attacks, which has been unattainable in previous studies. The experimental results show that our scheme takes little time regardless of file size and achieves solid performance in handling concurrent requests; furthermore, it is innocuous for clients, and the memory usage is acceptable.

Climate Change in Court: Overcoming Procedural Hurdles in Transboundary Environmental Cases

Climate change and its consequences will likely be the defining human rights challenge of the 21st Century. The European Court of Human Rights is well-placed to help shape the response to this looming crisis. Indeed, the first four applications concerning climate change have recently been filed before the Court. However, the applicants in these pending cases, as well as potential applicants in any future climate cases, will have to overcome significant procedural hurdles to ensure that the Court will hear their arguments on the merits. This article discusses some of the most significant issues that applicants seeking to bring climate cases will face, which include proving exhaustion of domestic remedies, establishing that the applicants have victim status, and demonstrating that the applicants face a significant disadvantage. This article considers how the Court can ensure that these admissibility hurdles do not preclude climate cases from receiving full consideration on the merits.

Ways to Translate a Newly-Introduced Concept

Translation is a complicated thinking and a practicing process, which involves many theories and skills. According to the theory of dynamic equivalence and based on literature studies as well as personal practical experiences, three viewpoints have been proposed in this article to discuss on how to translate a newly-introduced concept; namely, giving full consideration to the meaning of newly-introduced concepts, paying attention to the evolution of the concepts, and seeking for a similar meaning in the traditional classics of a nation, each of which is exemplified in order to facilitate understanding.

Racism and Religious Intolerance: A Critical Analysis of the Coloniality of Brazilian Christianity

This article examines the persistence of religious intolerance experienced by practitioners of Afro-Brazilian religions. Drawing from recent reports and historical resources on religious intolerance, it approaches religious diversity in Brazil from a decolonial perspective, pointing to the contradiction between the image of Brazil as a place where religious change and plurality occurs with minimal conflict and the painful reality experienced by practitioners of Afro-Brazilian religions. Picturing religious intolerance and racism as two faces of the same coin, it argues that both must be resisted. The article concludes with a call for a religious-racial literacy which is intercultural in nature and promises a path to overcome the insidious persistence of racism and religious intolerance. Such a way forward, however, demands a de-centering of Brazilian Christianity, despite its religious majority status, in favor of an epistemic humility which gives full consideration to the knowledge, memories, and lived experience of Afro-Brazilian religious practitioners.

The Analysis of Mechanical Properties and Lightweight Design of Nonmetallic Armored Umbilical Cable

Due to the development of gas and oil exploration into the deep sea, the effective tensile capacity provided by armored steel wire will decrease rapidly with the increase of the weight of umbilical cables. In this paper, two designs of lightweight umbilical cables were studied in full consideration of the geometric characteristics, and the mechanical properties were investigated under tension, bending, and torsion. The contact and friction between the components of the umbilical cables were also included in the model. Three cases are presented for validation from theoretical and finite element methods. The discussion on variables was carried out from the views of friction coefficient and helically wound angle. Compared with the steel tube umbilical model, the nonmetallic armored umbilical cable shows higher tensile strength and more flexibility. With the increase of friction coefficient, the stiffness of umbilical cable models don't change much. The helically wound angle has a great influence on the tensile stiffness and bending stiffness but little effect on the torsional rigidity. The proposed lightweight model can be applicable to 6000m water depth. This research can benefit the design of umbilical cables to achieve the goal of high tensile capacity in deepwater applications.

Social and economic profitability of alternative measures to detention face to face with the visibility of the Romanian national probation system

20 years after the issue of Ordonnance 92/2000 which was establishing the need to provide services for the social reintegration of offenders and supervision for non-custodial sanctions, called from 2006 probation services, a national study was carried out on the visibility of probation system among citizens. The respondents were all the probation services Chiefs in the country and their opinion confirmed the hypothesis that the National Probation System, ignoring the recommendations of the Committee of Ministers of European Council, don't have a promoting strategy nither the concern for creating a recognizable image among the other actors involved in the justice act. Consequently, the field has so far failed to gain full consideration within the Romanian Criminal Justice System and visibility among citizens, although after 2014 when the New Criminal Code started to be applied, the number of offenders attended by probation services was tripled and the staff's attributions war extended. The article is structured in two parallel planes, first showing the social and economic benefits of alternative detention measures supervised by probation services in the light of the costs of incarceration and the second showing the unfair lack of visibility of these benefits and the unknown activity carried out by probation counselors for the social reintegration of offenders.

A new model to identify node importance in complex networks based on DEMATEL method

It is still a hot research topic to identify node importance in complex networks. Recently many methods have been proposed to deal with this problem. However, most of the methods only focus on local or path information, they do not combine local and global information well. In this paper, a new model to identify node importance based on Decision-making Trial and Evaluation Laboratory (DEMATEL) is presented. DEMATEL method is based on graph theory which takes the global information into full consideration so that it can effectively identify the importance of one element in the whole complex system. Some experiments based on susceptible-infected (SI) model are used to compare the new model with other methods. The applications in three different networks illustrate the effectiveness of the new model.

Separating the apples from the oranges: from NAFLD heterogeneity to personalized medicine

Recently, Arrese and Colleagues have published a review article entitled, “Insights into Nonalcoholic Fatty-Liver Disease (NAFLD) Heterogeneity” (Semin Liver Dis. 2021;41:421-34. doi: 10.1055/s-0041-1730927). This milestone publication clearly and exhaustively explains the multitude of pathogenic pathways involved in the development and progression of disease eventually conducive to heterogeneous clinical phenotypes and different disease outcomes. The present commentary first briefly discusses the biological grounds of NAFLD heterogeneity and then illustrates the work by Arrese et al. In conclusion, the presently adopted nomenclatures appear inadequate in rendering the complexity of disease in the individual patient. In order to adopt the principles of personalized care, what remains to be done is to propose and validate a simple and accurate classification system. This should give full consideration to the principal disease modifiers and should shape a scheme to be adopted in both clinical practice and in the research arena. Care should be taken to not neglect the systemic nature of disease.

Evaluating Elimination Thresholds and Stopping Criteria for Interventions Against the Vector-borne Macroparasitic Disease, Lymphatic Filariasis, Using Mathematical Modelling

We leverage the ability of the EPIFIL transmission model fit to field data for allowing calculations of the probabilities of transmission elimination and recrudescence once infection levels are predicted to fall below the threshold used in the WHO Transmission Assessment Surveys (TAS) versus site-specific model-estimated thresholds to evaluate the implications of using these thresholds for making Lymphatic Filariasis (LF) intervention stopping decisions. Our results, overall, indicate that understanding the underlying parasite transmission and extinction dynamics will be crucial for choosing the right intervention stopping thresholds, and indeed the right interventions connected with these thresholds, if we are to bring about the sustainable elimination of LF. They also warn that applying stopping criteria set for operational purposes without a full consideration of population dynamics, as employed in the current TAS strategy, could, by risking infection recrudescence especially over the long-term, seriously undermine the goal of achieving global LF elimination.
