Link prediction of heterogeneous complex networks based on an improved embedding learning algorithm

Plos.org 
En

by Lang Chai, Rui Huang

Link prediction in heterogeneous networks is an active research topic in the field of complex network science. Recognizing the limitations of existing methods, which often overlook the varying contributions of different local structures within these networks, this study introduces a novel algorithm named SW-Metapath2vec. This algorithm enhances the embedding learning process by assigning weights to meta-path traces generated through random walks and translates the... Читать дальше...

A two-stage hybrid NSGA-III with BWO for path planning and task allocation in agricultural land preparation

Plos.org 
En

by Manxian Yang, Yanhong Chen, Yongke Li, Taihong Zhang, Tianlun Wu

Automated large-scale farmland preparation operations face significant challenges related to path planning efficiency and uniformity in resource allocation. To improve agricultural production efficiency and reduce operational costs, an enhanced method for planning land preparation paths is proposed. In the initial stage, unmanned aerial vehicles (UAVs) are employed to collect data from the field, which is then used to construct accurate farm models. Читать дальше...

Anomaly detection in virtual machine logs against irrelevant attribute interference

Plos.org 
En

by Hao Zhang, Yun Zhou, Huahu Xu, Jiangang Shi, Xinhua Lin, Yiqin Gao

Virtual machine logs are generated in large quantities. Virtual machine logs may contain some abnormal logs that indicate security risks or system failures of the virtual machine platform. Therefore, using unsupervised anomaly detection methods to identify abnormal logs is a meaningful task. However, collecting accurate anomaly logs in the real world is often challenging, and there is inherent noise in the log information. Читать дальше...



The Bimanual Observation of The Hands (BOTH): Development, reliability, and validity for stroke rehabilitation

Plos.org 
En

by Debbie Rand, Nitsan Omer, Amihai Levkoviz, Samar Assadi Khalil

Importance

To efficiently perform bimanual daily tasks, bimanual coordination is needed. Bimanual coordination is the interaction between an individual’s hands, which may be impaired post-stroke, however clinical and functional assessments are lacking and research is limited.

Objectives

To develop a valid and reliable observation tool to assess bimanual coordination of individuals post-stroke.

Design

A cross-sectional study. Читать дальше...

Effects of pre-oxidation temperature and air volume on oxidation thermogravimetric and functional group change of lignite

by Baoshan Jia, Zihao Chai, Wanting Zhao, Xian Wu

To investigate the impact of the oxidation temperature and variations in airflow conditions on coal spontaneous combustion characteristics, pre-oxidized coal samples were prepared using a programmed temperature rise method. Synchronous thermal analysis experiments and Fourier transform infrared spectroscopy were conducted to explore changes in the thermal effects and functional group content of the coal samples, respectively. The results indicate... Читать дальше...

Effects of the pan-caspase inhibitor Q-VD-OPh on human neutrophil lifespan and function

Plos.org 
En

by Lisa Khuu, Alisha Pillay, Allan Prichard, Lee-Ann H. Allen

Human neutrophils are abundant, short-lived leukocytes that turn over at a rate of approximately 1011 cells/day via a constitutive apoptosis program. Certain growth factors, inflammatory mediators and infectious agents can delay apoptosis or induce neutrophils to die by other mechanisms. Nonetheless, a large body of data demonstrates that apoptosis of untreated neutrophils typically ensues within 24 hours of cell isolation and in vitro culture. Читать дальше...

Association of varicose veins with the risk of heart failure: A nationwide cohort study

Plos.org 
En

by Dongyeop Kim, Moo-Seok Park, Ju-young Park, Tae-Jin Song

Background

Research investigating the association between varicose veins (VV) and heart failure has been limited. Here, we examine this association within a nationwide longitudinal cohort, hypothesizing an increased risk of heart failure associated with the presence of VV.

Methods

Our study included 390,436 participants based on health screening results conducted from 2005 to 2010 in the South Korean health screening cohort database. Читать дальше...

Research on boundary control of vehicle-mounted flexible manipulator based on partial differential equations

En

by Yuzhi Tang

Vehicle-mounted flexible robotic arms (VFRAs) are crucial in enhancing operational capabilities in sectors where human intervention is limited due to accessibility or safety concerns, such as hazardous environments or precision surgery. This paper introduces the latest generation of VFRAs that utilize advanced soft materials and are designed with elongated structures to provide greater flexibility and control. We present a novel mathematical model, derived using Hamilton’s principle... Читать дальше...

Gender difference in domain-specific quality of life measured by modified WHOQoL-BREF questionnaire and their associated factors among older adults in a rural district in Bangladesh

Plos.org 
En

by Fakir M. Amirul Islam

Background

The global population of older adults has steadily increased in recent decades. Little is known about the gender difference in the quality of life (QoL) of older adults in the general population. This study aimed to identify factors associated with QoL among older adults by gender.

Method

Data on QoL using the World Health Organization Quality of Life (WHOQoL-BREF) questionnaire and socio-demographic characteristics, including living status and sources of income... Читать дальше...
