Objective: To investigate the relationship between apathy and subjective cognitive decline (SCD) in commu-nity-dwelling older ***: A total of 211 participants without objective cognitive impairment were included in this study. Their SCD, apathy, sleep quality, depression, and anxiety were assessed by face-to-face interviews. Multivari-ate logistic regression was constructed to examine the independent relationship between apathy and SCD with adjustment for ***: The participants' average SCD-questionnaire and apathy evaluation scale-self scores were 7.13 and 30.65, respectively. Nearly half of the participants were categorized as having SCD. A quarter of participants were identified as apathetic. The apathy score was significantly associated with an increased risk of SCD (odds ratio 1.05, 95% confidence interval 1.01-1.10) after controlling for ***: Apathy was independently and significantly associated with SCD in community-dwelling older adults without objective cognitive impairment. Thus early intervention on apathy is important to protect elderly cognitive functioning.(c) 2022 Elsevier Inc. All rights reserved.

arXiv 2024年

作者： Ge, Huabin Meng, Yunpeng wang, chuwen Yang, Yuxuan School of Mathematics Renmin University of China Beijing100872 China School of Mathematical Sciences Capital Normal University Beijing100048 China Beijing International Center for Mathematical Research Peking University Beijing100871 China

For a twist knot Kp′, let M be the closed 3-manifold obtained by doing (p, q) Dehn-filling along Kp′. In this article, we prove that Chen-Yang’s volume conjecture holds for sufficiently large |p|+ |q| and |p′| for M. In the proof, we construct a new ideal triangulation of the Whitehead link complement which is different from Thurston’s triangulation. Our triangulation has led to some new discoveries regarding symmetry, including insights into "sister manifolds" as introduced by Hodgson, Meyerhoff, and Weeks. © 2024, CC BY-NC-ND.

Cryptococcosis is an invasive fungal disease with increased morbidity in China over the past two decades. Cryptococci can infect immunocompromised hosts as well as immunocompetent ones. In this study, we reviewed data of 71 inpatients with cryptococcosis at Ningbo First Hospital from May 2010 to May 2020 and compared the clinical profiles of pulmonary cryptococcosis (PC) and extrapulmonary cryptococcosis (EPC). Of 71 patients (38 males, 33 females), 70 were non-HIV. The annual inpatient population increased dramatically, especially in the PC group. PC was confirmed in 77.46% (55/71) of cases by pathology. The rest were EPC including intracranial infection (15.49%, 11/71) and cryptococcemia (7.04%, 5/71). Compared with PC, a larger proportion of EPC patients were found to have immunocompromised conditions judged by predisposing factors (p < 0.01), or detectable humoral or cellular immunodeficiency. Fever and headache were more common in EPC patients (p < 0.001). Patients with EPC had lower serum sodium level (p = 0.041), lower monocyte counts (p = 0.025) and higher C-reactive protein (p = 0.012). In our study, the sensitivity of cryptococcus antigen detection for EPC was 100% regardless of sample type, while serum lateral flow assay (LFA) tested negative in 25% (5/20) of PC. Immunocompromised hosts are more likely to suffer from EPC than PC.

The carbon market is a vital tool to achieve carbon neutrality. This paper uses daily closing price data of Shenzhen carbon trading market, energy, commodity and financial markets from 18 October 2018 to 19 August 2021, examining the transmission of risk/information from the perspective of market volatility spillover and tail risk transmission based on quantile spillover. The stock market crash and COVID-19 have increased the volatility of the system substantially. Next, the increase in trading frequency is accompanied by an increase in total volatility connectivity, and the carbon market transforms into a recipient of systemic shocks. Finally, the results of tail risk transmission reveal that the net effect of carbon reception increases significantly. These findings have implications for policymakers to improve the carbon market and provide important insights for investors to trade in turbulent periods.

Toward the integration of European gas futures market under COVID-19 shock: A quantile connectedness approach

Natural gas is an essential resource to achieve energy transition and carbon neutrality, and the allocation of natural gas resources depends on the integrated development of the natural gas market. This paper presents a quantile spillover approach to measure changes in the integration of the European gas futures market when major events occur. The empirical results show that extreme events exacerbate the transmission of market risk, and COVID-19 has weakened market integration. The arrival of severe cold weather led to a supply and demand imbalance in the market, and the level of market resource integration was hit hard. In addition, when active and effective reform policies are implemented, they help restore market connectivity. From the perspective of risk transmission within the system, this paper also finds that liberalized or highly liquid hubs can better cope with extreme risks. The findings have implications for policymakers to improve market integration and provide important insights for investors to trade during turbulent times such as COVID-19.

Next-Generation Simulation Illuminates Scientific Problems of Organised Complexity

As artificial intelligence becomes increasingly prevalent in scientific research, data-driven methodologies appear to overshadow traditional approaches in resolving scientific problems. In this Perspective, we revisit a classic classification of scientific problems and acknowledge that a series of unresolved problems remain. Throughout the history of researching scientific problems, scientists have continuously formed new paradigms facilitated by advances in data, algorithms, and computational power. To better tackle unresolved problems, especially those of organised complexity, a novel paradigm is necessitated. While recognising that the strengths of new paradigms have expanded the scope of resolvable scientific problems, we aware that the continued advancement of data, algorithms, and computational power alone is hardly to bring a new paradigm. We posit that the integration of paradigms, which capitalises on the strengths of each, represents a promising approach. Specifically, we focus on next-generation simulation (NGS), which can serve as a platform to integrate methods from different paradigms. We propose a methodology, sophisticated behavioural simulation (SBS), to realise it. SBS represents a higher level of paradigms integration based on foundational models to simulate complex systems, such as social systems involving sophisticated human strategies and behaviours. NGS extends beyond the capabilities of traditional mathematical modelling simulations and agent-based modelling simulations, and therefore, positions itself as a potential solution to problems of organised complexity in complex systems.

The development of social media platforms has brought global attention to short video applications;in China, this is especially true of Douyin. This study aims to find out: how different generations of people perceive and react to this age of short video dominance;what factors affect behaviors towards Douyin usage;and what level of influence each of these factors has on the behaviours. From the established scholarship, we gleaned insights to develop our framework of various motivation and hindrance factors that may influence each generation's response to short video application usage. We then conducted a survey that garnered responses from 169 participants to evaluate the extent of influence each factor had on the different generations. This led to a further examination of both their attitudes towards Douyin, and their usage of Douyin, measured by time spent on the application. Our results found three main factors that motivate users to use Douyin: to seek entertainment;to seek self-status;and to disseminate information. On the other hand, the most common factors that hinder users from using Douyin are: dissatisfaction with content and how immersed one is made to become when using the application. The results for Generation Z also show a distinctive difference in time spent on Douyin, compared to that of Generations X and Y. This age factor plays a crucial role in mediating how much time a user spends on Douyin, with each generation identifying different purposes for using the application.

We obtain a priori L∞ estimate for a general class of (n − 1)−form fully nonlinear partial differential equations on compact Hermitian manifolds. Our method relies on the local version of comparison with auxiliary Monge-Ampère equations, developed earlier by B. Guo and D. H. Phong. The key is to find the appropriate elliptic operator such that the maximum principle applies. © 2022, CC BY.
