This study explores the variations in address forms within the Tinghu dialect of Yancheng city.The findings reveal that the ways individuals address one another in this region deviate from the established principles of tone sandhi theory.In Chinese phonology,it is generally assumed that individual characters serve as fundamental forms based on their standard pronunciations,with real-time pronunciations adapting to phonetic conditions.However,the study of address forms has not traditionally been integrated into this framework.Observations indicate that a wide range of addressing methods is employed in social interactions,reflecting the complexity of regional cultural traits and social dynamics.This research highlights the distinctive features of address forms in the Tinghu dialect,particularly in terms of tone sandhi,vocative expressions,and indirect address.By examining these unique characteristics,the study enhances our understanding of the principles governing tonal changes in Chinese.Furthermore,it offers valuable insights into the preservation and inheritance of regional dialects. 展开更多

High-performance, large-area optical gratings for applications like chirped pulse amplification, gravitational wave astronomy, and X-ray optics require sub-nanometer line placement control over several cm^(2). Electron beam lithography with a variable shaped beam(VSB) is well suited but limited by tool-dependent address grid discretization. We adapted address grid interpolation to the VSB method, reducing the effective placement grid to 25 pm, as confirmed by stray light measurements. 展开更多

The increasing reliance on interconnected Internet of Things(IoT)devices has amplified the demand for robust anonymization strategies to protect device identities and ensure secure communication.However,traditional anonymization methods for IoT networks often rely on static identity models,making them vulnerable to inference attacks through long-term observation.Moreover,these methods tend to sacrifice data availability to protect privacy,limiting their practicality in real-world applications.To overcome these limitations,we propose a dynamic device identity anonymization framework using Moving Target Defense(MTD)principles implemented via Software-Defined Networking(SDN).In our model,the SDN controller periodically reconfigures the network addresses and routes of IoT devices using a constraint-aware backtracking algorithmthat constructs new virtual topologies under connectivity and performance constraints.This address-hopping scheme introduces continuous unpredictability at the network layer dynamically changing device identifiers,routing paths,and even network topology which thwarts attacker reconnaissance while preserving normal communication.Experimental results demonstrate that our approach significantly reduces device identity exposure and scan success rates for attackers compared to static networks.Moreover,the dynamic schememaintains high data availability and network performance.Under attack conditions it reduced average communication delay by approximately 60% vs.an unprotected network,with minimal overhead on system resources. 展开更多

As a typical in-memory computing hardware design, nonvolatile ternary content-addressable memories(TCAMs) enable the logic operation and data storage for high throughout in parallel big data processing. However,TCAM cells based on conventional silicon-based devices suffer from structural complexity and large footprintlimitations. Here, we demonstrate an ultrafast nonvolatile TCAM cell based on the MoTe2/hBN/multilayergraphene (MLG) van der Waals heterostructure using a top-gated partial floating-gate field-effect transistor(PFGFET) architecture. Based on its ambipolar transport properties, the carrier type in the source/drain andcentral channel regions of the MoTe2 channel can be efficiently tuned by the control gate and top gate, respectively,enabling the reconfigurable operation of the device in either memory or FET mode. When working inthe memory mode, it achieves an ultrafast 60 ns programming/erase speed with a current on-off ratio of ∼105,excellent retention capability, and robust endurance. When serving as a reconfigurable transistor, unipolar p-typeand n-type FETs are obtained by adopting ultrafast 60 ns control-gate voltage pulses with different polarities.The monolithic integration of memory and logic within a single device enables the content-addressable memory(CAM) functionality. Finally, by integrating two PFGFETs in parallel, a TCAM cell with a high current ratioof ∼10^(5) between the match and mismatch states is achieved without requiring additional peripheral circuitry.These results provide a promising route for the design of high-performance TCAM devices for future in-memorycomputing applications. 展开更多

NAT回流是NAT技术的关键应用场景之一,解决了内网主机通过公网地址访问内部服务器的问题。该研究针对NAT Hairpin、双向NAT和NAT Policy三种主流回流范式,通过仿真实验分析其工作机制,提供核心配置与测试方案,并系统对比三者的性能特点。结果表明:在性能方面,NAT Hairpin时延最低,双向NAT次之,NAT Policy因策略匹配开销较大而时延最高;在配置与安全方面,NAT Policy支持多维度策略控制,灵活性最强,双向NAT通过双向转换提升安全性,NAT Hairpin配置简便但受设备兼容性限制。研究成果可为不同网络环境中NAT回流方案的选择提供理论参考与实践指导。 展开更多

Within the scope of human beings, some addressing terms are similar. However, different addressing terms still exist,which are influenced by the background of high context communication or low context communication. A good example is that Chinese traditional culture, a typical instance of high context communication, puts much emphasis on etiquette, which is represented in addressing terms as more complex and definite; In western, with the background of low context communication, every individual is more equal and they address each other more generally and much simpler. This paper tries to explore the addressing terms both in Chinese and in English from the perspective of frame theory. 展开更多
