    As a city rich in petroleum and coal, there are two pillar industries in Yan’an city. This essay is going to analyze the long term effect of mineral resources development on the city’s economy in respect of regression analysis method and on its fiscal revenue and expenditure employment and resident’s income, ecological environment, and the development differences among each area countries in terms of qualitative analysis method. The aim of this essay is to analyze the influences and the effects of mineral resources development on Yan’an overall society and economy so as to provide testimonies for the significant effects of mineral resources development in regional social and economic development.Key words: Exploitation of mineral resources; Yan’an city; Development; Influence

    The Effect of Tactile Training on Sustained Attention in Young Adults

    Sustained attention is crucial for higher-order cognition and real-world activities. The idea that tactile training improves sustained attention is appealing and has clinical significance. The aim of this study was to explore whether tactile training could improve visual sustained attention. Using 128-channel electroencephalography (EEG), we found that participants with tactile training outperformed non-trainees in the accuracy and calculation efficiency measured by the Math task. Furthermore, trainees demonstrated significantly decreased omission error measured by the sustained attention to response task (SART). We also found that the improvements in behavioral performance were associated with parietal P300 amplitude enhancements. EEG source imaging analyses revealed stronger brain activation among the trainees in the prefrontal and sensorimotor regions at P300. These results suggest that the tactile training can improve sustained attention in young adults, and the improved sustained attention following training may be due to more effective attentional resources allocation. Our findings also indicate the use of a noninvasive tactile training paradigm to improve cognitive functions (e.g., sustained attention) in young adults, potentially leading to new training and rehabilitative protocols

    Brain Resource Occupancy: A Novel User-Centered Criteria for Brain-computer Interface Performance Evaluation

    No full text
    Brain-computer interfaces (BCIs) offer a direct channel for communication between external devices and the user's central nervous system, holding significant promise for restoring limb mobility in patients, particularly those afflicted by conditions such as peripheral nerve injury. However, the widespread utilization of BCIs is impeded by the absence of an objective and user-centric evaluation system. This paper proposes a novel BCI evaluation index termed "brain resource occupancy," serving as a quantitative measure of an individual's cognitive resource utilization at any given moment. Derived from cognitive psychology, this metric is perceived as a crucial determinant of performance across various single-task and multi-task scenarios. The paper delves into the concept of brain resource occupancy, its significance, measurement techniques, and underscores its potential to objectively assess BCI system performance from the user's viewpoint. Additionally, it explores the correlation between brain resource occupancy and the privacy protection and security facets within the realm of BCIs

    Recently, Toll-like receptors (TLRs) have been extensively studied in radiation damage, but the inherent defects of high toxicity and low efficacy of most TLR ligands limit their further clinical transformation. CRX-527, as a TLR4 ligand, has rarely been reported to protect against radiation. We demonstrated that CRX-527 was safer than LPS at the same dose in vivo and had almost no toxic effect in vitro. Administration of CRX-527 improved the survival rate of total body irradiation (TBI) to 100% in wild-type mice but not in TLR4-/- mice. After TBI, hematopoietic system damage was significantly alleviated, and the recovery period was accelerated in CRX-527-treated mice. Moreover, CRX-527 induced differentiation of HSCs and the stimulation of CRX-527 significantly increased the proportion and number of LSK cells and promoted their differentiation into macrophages, activating immune defense. Furthermore, we proposed an immune defense role for hematopoietic differentiation in the protection against intestinal radiation damage, and confirmed that macrophages invaded the intestines through peripheral blood to protect them from radiation damage. Meanwhile, CRX-527 maintained intestinal function and homeostasis, promoted the regeneration of intestinal stem cells, and protected intestinal injury from lethal dose irradiation. Furthermore, After the use of mice, we found that CRX-527 had no significant protective effect on the hematopoietic and intestinal systems of irradiated TLR4-/- mice. in conclusion, CRX-527 induced differentiation of HSCs protecting the intestinal epithelium from radiation damage.</p
