M-ReDet: A mamba-based method for remote sensing ship object detection and fine-grained recognition

by Xuhui Liu, Chi Feng, Shuran Zi, Zhengkun Qin, Qinghe Guan

Ship object detection and fine-grained recognition of remote sensing images are hot topics in remote sensing image processing, with applications in fishing vessel operation command, merchant ship navigation route planning, and other fields. In order to improve the detection accuracy for different types of remote sensing ship objects, this paper proposes a ship object perception and feature refinement method based on the improved ReDet, called Mamba-ReDet (M-ReDet).

Malnutrition among under-five children in amhara and oromia regions, Ethiopia: Continuous time markov multi-state modeling

by Dafa Duge Wachifo, Dereje Danbe Debeko, Zeytu Gashaw Asfaw

Background

Ethiopia faces a high burden of undernutrition prevalence, ranking among the 15 worst-affected nations globally. So, this study aimed to find out how often and how long under-five children (U5C) in Ethiopia’s Amhara and Oromia regions move between different states of Composite Index Anthropometry Failure (CIAF) as well as what factors influence these changes.

Methods

The data used for this study was extracted... Читать дальше...

Modeling the formation of a worldwide health network fighting TBC: Key drivers in policy, management and governance in developing countries and global health institutions

by Mauro Gallegati, Milena Lopreite, Michelangelo Puliga

We present an original study on the usage of a model of network formation to analyze the X (formerly Twitter) friendship network relative to the health organizations that are fighting a specific infectious disease such as Tuberculosis (TBC) as well as how the network evolves over time. Using this model, that mixes information from social media and the underlying reconstructed economic network of their actors, together with disease incidence information... Читать дальше...

An efficient hybrid reliability analysis method with application to the harmonic drive

by Jingqi Cui, Di Zuo, Xiaoxi Men, Chongshuai Wang

The harmonic drive is a new type of high-efficiency gear transmission system, widely used in precision machinery, robotics, and aerospace due to its compact structure and high transmission accuracy, and the multiple uncertain parameters in it will seriously affect its transmission performance. In this paper, the limit state functions for multiple failure modes of harmonic drive are established based on the stress-strength interference theory. Читать дальше...

Advancing fall risk prediction in older adults with cognitive frailty: A machine learning approach using 2-year clinical data

by Catherine Park, Namhee Kim, Miji Kim, Chang Won Won, Beom-Chan Lee

Falls are a critical concern in older adults with cognitive frailty (CF). However, previous studies have not fully examined whether machine learning models can predict falls in older individuals with CF. The 2-year longitudinal data set from the Korean Frailty and Aging Cohort Study and machine learning approach were utilized to predict fall risk. We analyzed multidimensional health data, including demographics, clinical conditions... Читать дальше...

A lightweight cross-scale feature fusion model based on YOLOv8 for defect detection in sewer pipeline

by Ruibo Sha, Zhifeng Zhang, Xiao Cui, Qingzheng Mu

Sewer pipeline defect detection is a critical task for ensuring the normal operation of urban infrastructure. However, the sewer environment often presents challenges such as multi-scale defects, complex backgrounds, lighting changes, and diverse defect morphologies. To address these issues, this paper proposes a lightweight cross-scale feature fusion model based on YOLOv8. First, the C2f module in the backbone network is replaced with the... Читать дальше...

EchoMamba: A new Mamba model for fast and efficient hyperspectral image classification

by Yancong Zhang, Xiu Jin, Xiaodan Zhang, Yuting Wu, Lijing Tu

The classification of hyperspectral images (HSI) is an important foundation in the field of remote sensing. Mamba architectures based on state space model (SSM) have shown great potential in the field of HSI processing due to their powerful long-range sequence modeling capabilities and the efficiency advantages of linear computing. Based on this theoretical basis, We propose a novel deep learning framework: long-sequence Mamba (EchoMamba)... Читать дальше...

Global burden and trends of age-related and other hearing loss: A 32-year analysis and future projections based on the GBD 2021

by Jiao Zhu, Min Yang, Cuiying Zhou, Houyong Kang, Deping Wang

Background

To evaluate the global, regional, and national burdens of and trends in age-related and other hearing loss (ARoHL) from 1990–2021 based on the Global Burden of Disease 2021 database.

Methods

This study examined trends and disparities in the prevalence and years lived with disability (YLDs) of patients with ARoHL across age, sex, and the sociodemographic index (SDI). The estimated annual percentage change (EAPC) was calculated to assess temporal trends. Читать дальше...

The effects of landscape on visual preference and fatigue recovery among university students: Differences in gender, grade level and major

by Chenyu Zheng, Ming Fang, Yue Zhang, Xinyu Liu, Zhihuan Huang

Exposure to natural landscapes has been shown to affect both physiological and psychological well-being, with the extent of these effects varying across different landscape types. However, the underlying mechanisms remain poorly understood. The association among stress reduction, environments characteristics and individual differences requires further investigation, particularly considering the complexity of landscape attributes and the variability of personal responses.

A cross-sectional study of COVID-19 testing and disclosure hesitancy: The role of responsibility attribution in South Korea

by Minjung Lee

Efficient and effective public health surveillance during epidemics relies heavily on active and voluntary public participation, including timely COVID-19 testing and disclosure of results to contacts. This study aimed to investigate predictors of COVID-19 testing and disclosure hesitancy, with a focus on the role of responsibility attribution during the early stages of the Omicron epidemic in South Korea. A cross-sectional survey was conducted with 1,000 participants between February 25 and March 2, 2022. Читать дальше...
