Abstract ：
Solar-blind ultraviolet photodetectors (SBUV-PDs) are utilized in various military and civilian fields, encompassing missile tracking, high-voltage detection, and fire warning systems. Ga2O3 emerges as the prime candidate for such PDs owing to its elevated bandgap, remarkable thermal stability, and facile fabrication process. The metal-semiconductor-metal (MSM) structure garners attention for its swift response time and straightforward preparation, thus becoming a focal point among diverse PD architectures. Nevertheless, the metal surface impedes optical absorption, thereby diminishing the quantum efficiency of the PD. In this work, we introduce a nanograting onto the Ga2O3 surface, which results in a 747-fold increase in responsivity in the SBUV region compared to a normal MSM grating-free structure. Metal gratings can induce surface plasmon polaritons (SPP), thereby augmenting the optical absorption of the PD and stimulating hot electrons to increase photocurrent. However, the broadband response caused by the introduction of metal gratings is a common problem. By optimizing the doping concentration of the Ga2O3 absorption layer, adjusting the incident light intensity, and reverse voltage, the problem of broadband response has been solved. The responsivity of the device in the non-SBUV region is suppressed 24-fold. This methodology holds promise as a reliable approach for fabricating high-performance SBUV-PDs.

Abstract ：
Mobile edge caching (MEC) has grown substantially with the rapid development in scale and complexity of data traffic. By exploiting the expansive coverage of autonomous aerial vehicles (AAVs), MEC enables services for massive vehicle users (VUs) simultaneously, which is promising for enhancing network transmission efficiency. Nonetheless, due to challenges arising from the timeliness and freshness of content services caused by AAVs' limited endurance and airborne capacity, caching strategy considering the real-time of content in large-scale dynamic Internet of Vehicles (IoV) environments remains open. With the above consideration, in this article, the cache refreshing cycle and content placement are jointly optimized in the cache-enabled AAV-assisted vehicular integrated networks (CAVINs) to minimize the content Age of Information (AoI) and energy consumption of the macro AAV. Since the joint optimization problem is variational coupled with nonconvex binary constraints, it is decoupled and solved by a double-iteration method. Specifically, the optimal cache refreshing cycle is derived in semi-closed form with the Karush-Kuhn-Tucker (KKT) conditions. The locally optimal solution of the content placement is obtained through successive convex approximation (SCA). Simulation results corroborate the effectiveness and superiority of the proposed scheme.

Abstract ：
For high-precision sensor applications, high dynamic range discrete-time delta-sigma modulators (DSMs) are key components. For the design of high dynamic range DSMs, the system architecture is crucial. The system requires strong in-band noise suppression for small input amplitudes and a large maximum stable amplitude (MSA) for large input amplitudes. This article presents the system design and optimization method of discrete- time delta-sigma modulator. It provides a detailed discussion on the behavior-level modeling and characteristics of low-bit and multi-bit quantizers. Additionally, design considerations of quantizers in DSM systems are analyzed. An approach for optimizing DSM systems by leveraging the properties of quantizers is proposed, along with a simple optimization case study. Potential future application scenarios are also presented. The purpose of this article is to offer design guidelines for developing well-performing DSMs systems.

Abstract ：
Remote sensing image-text retrieval (RSITR) is a cross-modal task that integrates visual and textual information, attracting significant attention in remote sensing research. Remote sensing images typically contain complex scenes with abundant details, presenting significant challenges for accurate semantic alignment between images and texts. Despite advances in the field, achieving precise alignment in such intricate contexts remains a major hurdle. To address this challenge, this article introduces a novel context-aware local-global semantic alignment (CLGSA) method. The proposed method consists of two key modules: the local key feature alignment (LKFA) module and the cross-sample global semantic alignment (CGSA) module. The LKFA module incorporates a local image masking and reconstruction task to improve the alignment between image and text features. Specifically, this module masks certain regions of the image and uses text context information to guide the reconstruction of the masked areas, enhancing the alignment of local semantics and ensuring more accurate retrieval of region-specific content. The CGSA module employs a hard sample triplet loss to improve global semantic consistency. By prioritizing difficult samples during training, this module refines feature space distributions, helping the model better capture global semantics across the entire image-text pair. A series of extensive experiments demonstrates the effectiveness of the proposed method. The method achieves an mR score of 32.07% on the RSICD dataset and 46.63% on the RSITMD dataset, outperforming baseline methods and confirming the robustness and accuracy of the approach.

Abstract ：
In hyperspectral images (HSIs), different land cover (LC) classes have distinct reflective characteristics at various wavelengths. Therefore, relying on only a few bands to distinguish all LC classes often leads to information loss, resulting in poor average accuracy. To address this problem, we propose a method called Cascaded Spatial Cross-Attention Network (CSCANet) for HSI classification. We design a cascaded spatial cross-attention module, which first performs cross-attention on local and global features in the spatial context, then uses a group cascade structure to sequentially propagate important spatial regions within the different channels, and finally obtains joint attention features to improve the robustness of the network. Moreover, we also design a two-branch feature separation structure based on spatial-spectral features to separate different LC Tokens as much as possible, thereby improving the distinguishability of different LC classes. Extensive experiments demonstrate that our method achieves excellent performance in enhancing classification accuracy and robustness.

Abstract ：
Monitoring the vacuum ultraviolet (VUV) radiation from the Sun by spaceborne photodetectors is an indispensable and crucial approach in solar physics research and atmospheric photochemistry investigations. Diamond-based photodetectors are emerging as ideal candidates to replace traditional silicon-based detectors for high-selectivity and radiation hardness. Here, a vertical Schottky photodiode based on p-type high-quality single-crystal diamond is presented. By modulating the diamond surface band structure and band alignment, an ultra-short response time of only 15 ns, and a photo-to-dark current ratio greater than 105 under the reverse bias are achieved. It is the first time to study the spectral response of the diamond photodiode in the range of 260 nm to as low as 120 nm under vacuum conditions, exhibiting an ideal selective responsivity and excellent imaging capability in the VUV range. This device holds promising prospects for coupling with optomechanical systems to enable a multidimensional detection of solar VUV radiation, including imaging and spectrum.

Abstract ：
Aluminum alloys are renowned for their lightweight nature, resistance to oxidation, and impressive mechanical properties. Despite these advantages, their mechanical performance deteriorates significantly in extreme environments. Herein, we present an innovative solution by developing aluminum matrix composites (AMCs) that incorporate 3D printed alumina ceramic lattices. Our investigation demonstrates a remarkable 112.4 % increase in the strength of AMCs compared to pure aluminum, with a concurrent 54.8 % improvement in modulus under identical conditions. Additionally, as the volume fraction of the ceramic lattice varies from 0.21 to 0.45, the modulus of AMCs exhibits a noteworthy increase, ranging from 96.2 to 106.5 GPa, surpassing that of pure aluminum (68.8 GPa). Notably, even at temperatures of up to 300 degrees C, the strength of the Al2O3-Al composite matrix remains stable at 477.3 MPa. X-ray computed tomography analysis elucidates that the structural integrity of these composites predominantly relies on the load-bearing capacity of the ceramic lattices, complemented by the damping effect provided by the aluminum matrix. This innovative approach not only paves the way for scalable production of high-strength metal alloys in the industrial sector but also holds promise for substantial economic opportunities in the near future.

Abstract ：
In recent years, the rapid development of the unmanned aerial vehicle (UAV) technology has generated a large number of aerial photography images captured by UAV. Consequently, the object detection in UAV aerial images has emerged as a recent research focus. However, due to the flexible flight heights and diverse shooting angles of UAV, two significant challenges have arisen in UAV aerial images: extreme variation in target scale and the presence of numerous small targets. To address these challenges, this article introduces a semantic information-guided fusion module specifically tailored for small targets. This module utilizes high-level semantic information to guide and align the underlying texture information, thereby enhancing the semantic representation of small targets at the feature level and subsequently improving the model's ability to detect them. In addition, this article introduces a novel global-local fusion detection strategy to strengthen the detection of small targets. We have redesigned the foreground region assembly method to address the drawbacks of previous methods that involved multiple inferences. Extensive experiments conducted on the VisDrone and UAVDT datasets demonstrate that our two self-designed modules can significantly enhance the detection capability of small targets compared with the YOLOX-M model. Our code is publicly available at: https://github.com/LearnYZZ/GLSDet.

Abstract ：
Optimized inductively coupled plasma (ICP) etching process can improve the surface quality of (1-Ga2O3 thin film to enhance the power figure of merit of (1-Ga2O3 Schottky barrier diodes (SBDs). However, the mechanism of surface quality improvement of ICP etching is not yet clear. In this letter, we verified that the surface qualities of (1-Ga2O3 SBDs could be modified by varying the ratios of BCl3 and Ar etching plasmas. Moreover, electrical performance tests were conducted to verify that the improved surface quality can enhance the electrical properties. Benefitted from the high surface quality of (1-Ga2O3 epitaxial layer, the (1-Ga2O3 SBD without termination structure exhibits a low specific on-resistance (Ron,sp) of 4 m Omega & sdot;cm2 and high breakdown voltage (BV) of 1500 V. These results can pave the way for the preparation of high-performance (1-Ga2O3 power SBDs.
