Abstract

ObjectiveTo explore the application value of the patient version of general practitioner assessment of cognition (P-GPCOG) for screening elderly with mild cognitive impairment (MCI) in community.MethodsA total of 905 elderly were recruited from West China Tianfu Hospital, Sichuan University and Chongzhou Second Hospital from April 2022 to November 2023, including 627 cases in normal cognitive function group (NC group) and 278 cases in MCI group. The cognitive function of the subjects was evaluated by P-GPCOG, the Montreal Cognitive Assessment (MoCA), and the 8-item ascertain dementia (AD8). The independence of daily living ability was evaluated by the Lawton Instrumental Activities of Daily Living Scale (IADLs). The Geriatric Depression Scale-15 (GDS-15) was used to assess the depressive symptoms of the subjects. The receiver operating characteristic (ROC) curve was drawn, and the area under the curve (AUC), sensitivity, specificity, positive predictive value and negative predictive value were calculated to evaluate the application value of GPCOG screening.ResultsCompared with the NC group, the MoCA and Lawton-IADL scores were significantly lower in the MCI group (PP=0.022). The AD8 and GDS-15 scores were significantly higher (PZ=15.001, PPCI (0.773, 0.836), P

Abstract

With the vigorous development of digital technology, the development of the digital economy has become an important component of the global economy. Against the background of negative growth of major global economies hit hard by the COVID-19 epidemic, the steadily rising digital economy has become a key force to boost the global economy and an important engine to promote global economic development. Northeast Asian countries should use the dividends released by the digital economy to promote the coordinated development of digital technology innovation within the region, respond to technological revolution and industrial transformation, and build new international competitive advantages. This article provides a detailed overview of the current development status of digital economy in various countries in Northeast Asia, analyzes the challenges faced by countries in the region in developing cross-border digital economic and trade cooperation from three aspects: political mutual trust, digital divide, and network security. It further proposes to build a cross-border digital service trade platform in Northeast Asia, establish a China North Russia Far East digital free trade zone, so as to promote the deepening of cooperation and common development in digital trade within the region.

Abstract

The paper focuses on improving the interpretability of Grammatical Error Correction (GEC) metrics, which receives little attention in previous studies. To bridge the gap, we propose CLEME2.0, a reference-based evaluation strategy that can describe four elementary dimensions of GEC systems, namely hit-correction, error-correction, under-correction, and over-correction. They collectively contribute to revealing the critical characteristics and locating drawbacks of GEC systems. Evaluating systems by Combining these dimensions leads to high human consistency over other reference-based and reference-less metrics. Extensive experiments on 2 human judgement datasets and 6 reference datasets demonstrate the effectiveness and robustness of our method. All the codes will be released after the peer review., Comment: 16 pages, 8 tables, 2 figures. Under review

Abstract

The current collector, one of the main components in the manufacture of composite electrodes, is mainly used to enhance the mechanical stability and improve the performance and cycle performance of the electrodes. During the electrochemical reaction, the lithium diffusion can induce compressive stress and affect the mechanical performance, lifespan, and performance of batteries. Therefore, this study analyzed the influence of copper foil on the mechanical response and degradation performance of electrodes. In addition, a mathematical model was developed to analyze the effect of copper foil on the stress–strain behavior of the electrodes. The results indicated that the stress and modulus of the graphite electrodes have a non-linear increase with the lithiation process. Based on those findings, utilizing a thinner and more compliant current collector could effectively mitigate the in-plane strain and the stress within electrodes. Thus, developing a thinner and softer copper foil could simultaneously enhance the mechanical properties and specific density of composite electrodes for the next-generation LiBs.

Abstract

This is a summary of a consensus statement on the introduction of "Ultrasound microvasculomics" produced by The Chinese Artificial Intelligence Alliance for Thyroid and Breast Ultrasound. The evaluation of microvessels is a very important part for the assessment of diseases. Super-resolution ultrasound (SRUS) microvascular imaging surpasses traditional ultrasound imaging in the morphological and functional analysis of microcirculation. SRUS microvascular imaging relies on contrast microbubbles to gain sensitivity to microvessels and improves the spatial resolution of ultrasound blood flow imaging for a more detailed depiction of vascular structures and hemodynamics. This method has been applied in preclinical animal models and pilot clinical studies, involving areas including neurology, oncology, nephrology, and cardiology. However, the current quantitative parameters of SRUS images are not enough for precise evaluation of microvessels. Therefore, by employing omics methods, more quantification indicators can be obtained, enabling a more precise and personalized assessment of microvascular status. Ultrasound microvasculomics - a high-throughput extraction of image features from SRUS images - is one novel approach that holds great promise but needs further validation in both bench and clinical settings. Clinical relevance statement: Super-resolution Ultrasound (SRUS) blood flow imaging improves spatial resolution. Ultrasound microvasculomics is possible to acquire high-throughput information of features from SRUS images. It provides more precise and abundant micro-blood flow information in clinical medicine. Key Points: This consensus statement reviews the development and application of super-resolution ultrasound (SRUS). The shortcomings of the current quantification indicators of SRUS and strengths of the omics methodology are addressed. "Ultrasound microvasculomics" is introduced for a high-throughput extraction of image features from SRUS images. [ABSTRACT FROM AUTHOR]
