Hemin treatment drives viral reactivation and plasma cell differentiation of EBV latently infected B cells

Plos.org 

by Anna M. Burnet, Tonya Brunetti, Rosemary Rochford

Epstein-Barr virus (EBV) and Plasmodium falciparum have a well described role in the development of endemic Burkitt lymphoma (BL), yet the mechanisms involved remain unknown. A major hallmark of malarial disease is hemolysis and bystander eryptosis of red blood cells, which causes release of free heme in large quantities into peripheral blood. We hypothesized that heme released during malaria infection drives differentiation of latently infected EBV-positive B cells... Читать дальше...

Knowledge distillation based on multi-layer fusion features

Plos.org 

by Shengyuan Tan, Rongzuo Guo, Jialiang Tang, Ning Jiang, Junying Zou

Knowledge distillation improves the performance of a small student network by promoting it to learn the knowledge from a pre-trained high-performance but bulky teacher network. Generally, most of the current knowledge distillation methods extract relatively simple features from the middle or bottom layer of teacher network for knowledge transmission. However, the above methods ignore the fusion of features, and the fused features contain richer information. Читать дальше...

“I think taking herbal medicine first can help prevent. If it doesn’t work, then can take start taking the medication given by the doctors. Patients’ perceptions towards hypertension in Fiji

Plos.org 

by Avock Johnny Jonathan, Masoud Mohammadnezhad, Filimone Raikanikoda

Background

Hypertension remains a public health challenge worldwide however, the prevention, detection, treatment and management of this condition are not highly prioritized. Health knowledge has an important impact on individual’s health. The ability to actively participate in screening, diagnosis and management of hypertension are influenced by patient’s knowledge of hypertension. To understand why hypertension is so difficult to control... Читать дальше...



Coherent feedback leads to robust background compensation in oscillatory and non-oscillatory homeostats

Plos.org 

by Melissa Nygård, Peter Ruoff

When in a reaction kinetic integral controller a step perturbation is applied besides a constant background, the concentration of a controlled variable (described as A) will generally respond with decreased response amplitudes ΔA as backgrounds increase. The controller variable E will at the same time provide the necessary compensatory flux to move A back to its set-point. A typical example of decreased response amplitudes at increased backgrounds is found in retinal light adaptation. Читать дальше...

Modelling consumers’ choice of novel food

Plos.org 

by Dawne Skinner, John Blake

A variety of approaches to reducing the environmental impact of food production and consumption are being explored including technological solutions, such as food produced via biotechnological processes. However, the development of these technologies requires significant upfront investment and consumer acceptance is not guaranteed. The purpose of this research is to develop a system dynamics model to forecast demand, under multiple marketing and quality scenarios... Читать дальше...

A wavelet based data coupling method for spatial damage detection in beam-type structures

Plos.org 

by Jianwei Zhao, Zhuo Zhou, Deqing Guan, Jia Guo

Spatial damage identification is of great significance in mechanical, aerospace, and civil engineering. In this study, a data coupling method based on continuous wavelet transform (CWT) is proposed to identify the spatial damage location of beam-type structures. The singularity of the wavelet coefficient can be used to identify the signal singularity, and data coupling method calculates the spatial location of the damage. Numerical simulations...

Changing face of socio-economic vulnerability and COVID-19: An analysis of country wealth during the first two years of the pandemic

Plos.org 

by Víctor Pérez-Segura, Raquel Caro-Carretero, Antonio Rua

There are numerous academic studies on the relationship between population wealth and the incidence of COVID-19. However, research developed shows contradictory results on their relationship. In accordance with this question, this work pursues two objectives: on the one hand, to check whether wealth and disease incidence have a unidirectional and stable relationship. And on the other hand, to find out if the country’s statistical... Читать дальше...

The effects of group adaptation on task performance: An agent-based approach

Plos.org 

by Darío Blanco-Fernández, Stephan Leitner, Alexandra Rausch

Organisations rely upon group formation to solve complex tasks, and groups often adapt to the demands of the task they face by changing their composition periodically. Previous research has often employed experimental, survey-based, and fieldwork methods to study the effects of group adaptation on task performance. This paper, by contrast, employs an agent-based approach to study these effects. There are three reasons why we do so. Читать дальше...

In silico epitope prediction and evolutionary analysis reveals capsid mutation patterns for enterovirus B

Plos.org 

by Hui Wang, Yulu Fang, Yongtao Jia, Jiajie Tang, Changzheng Dong

Enterovirus B (EVB) is a common species of enterovirus, mainly consisting of Echovirus (Echo) and Coxsackievirus B (CVB). The population is generally susceptible to EVB, especially among children. Since the 21st century, EVB has been widely prevalent worldwide, and can cause serious diseases, such as viral meningitis, myocarditis, and neonatal sepsis. By using cryo-electron microscopy, the three-dimensional (3D) structures... Читать дальше...

FPLV: Enhancing recommender systems with fuzzy preference, vector similarity, and user community for rating prediction

Plos.org 

by Zhan Su, Haochuan Yang, Jun Ai

Rating prediction is crucial in recommender systems as it enables personalized recommendations based on different models and techniques, making it of significant theoretical importance and practical value. However, presenting these recommendations in the form of lists raises the challenge of improving the list’s quality, making it a prominent research topic. This study focuses on enhancing the ranking quality of recommended items in user lists while ensuring interpretability. Читать дальше...
