Terahertz biotechnology has been increasingly applied in various biomedical fields and has especially shown great potential for application in brain sciences.In this article,we review the development of terahertz biotechnology and its applications in the field of neuropsychiatry.Available evidence indicates promising prospects for the use of terahertz spectroscopy and terahertz imaging techniques in the diagnosis of amyloid disease,cerebrovascular disease,glioma,psychiatric disease,traumatic brain injury,and myelin deficit.In vitro and animal experiments have also demonstrated the potential therapeutic value of terahertz technology in some neuropsychiatric diseases.Although the precise underlying mechanism of the interactions between terahertz electromagnetic waves and the biosystem is not yet fully understood,the research progress in this field shows great potential for biomedical noninvasive diagnostic and therapeutic applications.However,the biosafety of terahertz radiation requires further exploration regarding its two-sided efficacy in practical applications.This review demonstrates that terahertz biotechnology has the potential to be a promising method in the field of neuropsychiatry based on its unique advantages. 展开更多

Special Purpose Rice (SPR) is a technology that consists of different rice varieties that were developed by Central Luzon State University. The unique varietal characteristics of SPR are pigmented, glutinous, good-yielding varieties planted in lowland areas. This study was conducted to increase farmers’ income through employing different promotion and extension activities and enterprise development. Data were analyzed using descriptive statistics. Cost and return and benefit-cost analysis were used to determine the financial benefits of using the SPR in different production systems. Results revealed that incorporating the following parameters is critical in the sustainable adoption of the SPR. Amongst them are: ensuring that recommended production technologies are strictly followed by the farmers, ensuring the quality of seeds for planting, the presence of a market for the produce, engaging the farmers in value-adding activities like processing, capability development in entrepreneurship, and adopting clustering approach of the farmers to address economies of scale in marketing and processing. The use of SPR produced an average yield of 6.11 MT/ha and 5.04 MT/ha during the dry and wet seasons from 2021-2023, respectively, higher than the usual varieties of inbred rice. The net benefit from producing a CLS-2 variety of SPR is higher than regular rice, having an average difference of Php 22,355.53 per hectare from 2021-2023. 展开更多

Cracks are important migration channels and storage spaces for oil and gas, and the peripheral cracks in the Ordos Basin have developed extensively after multiple tectonic movements. Using unmanned aerial vehicle oblique photogrammetry technology to obtain field outcrop image data and establish a three-dimensional model for observation, the NEE and NNW fractures are the most developed in the Yanchang Formation of the study area, while the NW and NNE fractures are slightly developed, all of which are high angle vertical fractures and belong to regional structural fractures. The NNW oriented cracks are restricted by the NEE oriented cracks and developed in the late stage. Combined with the analysis of regional geological background, fracture intersection relationship and tectonic stress field, it is considered that there are two stages of fractures in Dongjiahe, namely, the late Indosinian and Yanshanian. 展开更多

The world today is undergoing disruptive,transformative shifts driven by a new wave of technological revolutions and industrial changes.In this context,a central question for China’s innovation-driven development strategy is how to effectively identify and measure high-quality technological innovations.Drawing on the stylized facts and scenario narrative of China’s technological landscape,this paper proposes a framework and measurement system for evaluating high-quality technological innovations.While China’s top-level design for technological innovation is guided by policy documents,the increasing number of enterprises applying for“high-tech enterprise”status has coincided with a decline in the quality of patent filings.In response,this paper first underscores the challenges and necessity of measuring the quality of technological innovations.Second,we introduce the high-quality technological innovation indicators and employ them to assess the quality of tech innovations at the firm level,utilizing an approach that combines analogical narrative,gene coding,text analysis,semantic logic,and a database of granted invention patents in China.Third,we examine the systematic and individual biases inherent in citation counts,a commonly used indicator,under specific contexts,and employ a granular instrumental variable approach to validate the effectiveness of the indicators.Finally,we develop a“family tree”of the indicators and explore their application scenarios through a combination of established and extended indicators.Our findings provide a theoretical foundation for evaluating China’s technological innovation quality,inform policy incentives,and offer insights for academia to apply high-quality technological innovation indicators in different contexts. 展开更多

To ameliorate the difficulties of on-site dynamic disaster control in the end-mining stage of traditional mining engineering,this paper introduces the mathematical research and engineering application of the end-mining technology system with non-pillar in mines(ETSNM)in recent years.The petal warning criterion for the stability of the surrounding rock of the roadway at the end-mining stage was obtained by studying the inverse problem of the petal theorem.A conformal mathematical model of the end-mining stage was established using the conformal mapping method,and the limit theorem of the peak point of mine pressure(LTPPMP)in the end-mining stage was demonstrated.Based on the cross-fusion of the above basic mathematical theory and the LTPPMP,a new ETSNM model was proposed,which includes no coal pillar,no dedicated retracement roadways,and fast retracement equipment(NNF).The mathematical principles of engineering technology for height control,speed limit,and roof cutting in the end-mining stage with non-pillar were revealed.The scientific and application values of the ETSNM were confirmed through engineering applications.Based on this,a new non-pillar control technology for dynamic disasters in the end-mining stage was proposed.The above research will play an active role in promoting the engineering application of ETSNM driven by mathematical theory. 展开更多
