<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[The aviation and aerospace transition zone, spanning altitudes between 50~250 km, constitutes a strategic arena for hypersonic weapon penetration and electronic warfare operations, serving as a critical battlefield that significantly impacts operational effectiveness. AI (artificial intelligence) is profoundly empowering the regions information warfare systems, driving their evolution toward dynamic and intelligent capabilities. Key AI technologies and applications across the entire “perception-fusion-prediction-countermeasure” chain are systematically reviewed: relying on deep learning for efficient inversion of environmental parameters; utilizing intelligent fusion to construct digital twins of battlefield environments; enhancing forecast accuracy through physical information; and developing autonomous learning and game-theoretic decision-making capabilities to support precise cognition and counter-interference.The core challenges facing AI-enabled information warfare include environmental perception uncertainty, weak model interpretability, difficulties in cross-domain transfer, and restricted data acquisition. Finally, the outlook for future development is presented, emphasizing that AI is evolving from a technical tool into a core driving force.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[A thermal concentrator is a thermal functional device based on transformation thermotics, effective-medium theory, and scattering-cancellation principles. By tailoring the spatial distribution of thermal conductivity or geometric configurations, it efficiently concentrates large-scale heat flux into localized regions, enabling precise control of both steady-state and transient heat transport. With advances in materials science and manufacturing technologies, research on the thermal concentrator is moving from theoretical models toward engineering implementation, and it shows application potential in microelectronic cooling, thermoelectric energy harvesting, energy heating, and thermal therapy. The physical mechanisms, structural designs, and implementation pathways of the thermal concentrator were systematically reviewed, summarized its development and representative works, compared the applicability and performance characteristics of different theoretical frameworks and configurations, and analyzed its technical advantages and engineering feasibility in typical application scenarios. Finally, future trends of the thermal concentrator were discussed, including extensions to complex geometries, multiscale systems, emerging energy platforms, and extreme thermal environments.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Absolute gravity measurement based on laser interferometry is the main means to establish a gravity measurement reference, and it is also the gravity reference instrument used currently. In recent years, along with the development of quantum absolute gravity measurement techniques, new opportunities have been presented for establishing a gravity reference with higher accuracy. With the support of the National Development and Reform Commission, Huazhong University of Science and Technology had established the “PGMF(precision gravity measurement facility)” as a major national scientific and technological infrastructure. A key component of this facility′s construction is the establishment of a micro-Gal level absolute gravity measurement reference station. This station provides a standardized reference for gravity measurement instruments and data, serving as a foundation for achieving high-precision measurements and applications in the gravitational field. High-precision gravity measurement instruments are the core equipment for PGMF to achieve a gravity measurement reference. For this purpose, PGMF independently developed a reference quantum absolute gravimeter suitable for station measurement and a miniaturized quantum absolute gravimeter for reference extension. Furthermore, a gravity comparison field and a background physical environment monitoring system were established. Ultimately, a micro-Gal level gravity measurement reference station was established.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[Fiber-based supercontinuum offer broad spectral bandwidth, high brightness, and excellent spatial coherence, showing great promise in applications such as electro-optical countermeasures, gas sensing, and optical coherence tomography. To address the diverse performance requirements of supercontinuum imposed by different application scenarios, this paper reviewed recent advances in three key directions of fiber-based supercontinuum: power scaling, long wave extension, and low noise research. The technical approaches tailored to enhance each specific performance metric were summarized, and an outlook on future developments was provided, aiming to serve as a reference for the development and application of high-performance supercontinuum.]]></description>

<description xmlns:cf="http://www.microsoft.com/schemas/rss/core/2005" cf:type="html"><![CDATA[DA (data assimilation) is a crucial technical method for improving the accuracy of atmospheric chemical forecasts by integrating the results of atmospheric chemistry models with multi-source observational data, reducing uncertainties in model input data. Centering on DA techniques for atmospheric chemistry models, the transformation process of initial field assimilation for pollutant gases and aerosols from single state variables to multi-state variables was systematically reviewed. Meanwhile, the important progress of pollutant emission source assimilation inversion using ensemble methods and four-dimensional variational methods was focused on the improvement of emission source accuracy, optimization of spatiotemporal resolution, and enhancement of pollutant concentration prediction performance. With the explosive growth of observational data, a core challenge in the current field lies in fully leveraging high-resolution geospatial and remote sensing data for atmospheric chemical DA. The deep integration of DA with artificial intelligence algorithms represents a key research direction to break through this bottleneck and significantly enhance the accuracy of atmospheric composition analysis and forecasting.]]></description>
