The rapid growth of CMOS logic circuits has surpassed the advancements in memory access,leading to significant “memory wall” bottlenecks, particularly in artificial intelligence applications. To address this challenge, compute-in-memory(CIM) has emerged as a promising approach to enhance the performance,area efficiency, and energy efficiency of computing systems. By enabling memory cells to perform parallel computations, CIM improves data reuse and minimizes data movement between the memory and the processor. This study conducts a comprehensive review of various domains of SRAM-based CIM macros and their associated computing paradigms. Additionally, it presents a survey of recent SRAM-CIM macros, with a specific focus on the key challenges and design tradeoffs involved. Furthermore, this research identifies potential future trends in SRAM-CIM macro-level design, including hybrid computing, precision enhancement, and operator reconfiguration. These trends aim to resolve the tradeoff between computational accuracy, energy efficiency, and support for diverse operators within the SRAM-CIM framework. At the microarchitecture level, two possible solutions for tradeoffs are proposed: chiplet integration and sparsity optimization. Finally,research perspectives are proposed for future development.

Aiming at the tracking problem of a class of discrete nonaffine nonlinear multi-input multi-output(MIMO) repetitive systems subjected to separable and nonseparable disturbances, a novel data-driven iterative learning control(ILC) scheme based on the zeroing neural networks(ZNNs) is proposed. First, the equivalent dynamic linearization data model is obtained by means of dynamic linearization technology, which exists theoretically in the iteration domain. Then, the iterative extended state observer(IESO) is developed to estimate the disturbance and the coupling between systems, and the decoupled dynamic linearization model is obtained for the purpose of controller synthesis. To solve the zero-seeking tracking problem with inherent tolerance of noise,an ILC based on noise-tolerant modified ZNN is proposed. The strict assumptions imposed on the initialization conditions of each iteration in the existing ILC methods can be absolutely removed with our method. In addition, theoretical analysis indicates that the modified ZNN can converge to the exact solution of the zero-seeking tracking problem. Finally, a generalized example and an application-oriented example are presented to verify the effectiveness and superiority of the proposed process.

为了保证新型强迫换流型真空直流限流断路器关断短路电流的可靠性，对该型断路器分断过程的真空介质恢复特性进行研究。设计了与断路器关断过程等效的介质恢复试验方案，通过等效试验结果和理论推演公式的拟合，得到了新型强迫换流型限流断路器真空灭弧室触头打开过程的动态介质强度恢复规律。研究结果表明：减小燃弧能量、提高触头运动速度可提高真空灭弧室介质的临界击穿电压；综合考虑燃弧时间与燃弧能量及触头开距的关系，随着燃弧时间的增加，真空灭弧室临界击穿电压先减小后增大。所得介质恢复规律可以作为新型断路器优化设计的参考依据。

Objective: To compare the clinical efficacy of artificial femoral head replacement and Proximal femoral nail antirotation (PFNA) in the treatment of unstable femoral intertrochanteric fractures in the elderly. Methods: This study retrospectively analyzed 60 elderly patients with unstable intertrochanteric fractures treated with PFNA and artificial femoral head replacement from 2015.06 to 2018.06, of which 34 were in the PFNA group (Group A) and 26 in the artificial femoral head replacement group (Group B). Statistical analysis of relevant surgical indicators such as surgical time, intraoperative blood loss, postoperative blood transfusion, postoperative time to landing, postoperative infection rate, hospital stay, number of secondary operations, postoperative VAS score, and postoperative Hip function score comparison. Results: All 60 patients were followed up for 1 - 24 months. Compared with the artificial femoral head replacement group, the operation time of PFNA group was shorter, the blood loss during operation was less, and the difference was statistically significant (P 0.05). Conclusion: The hip joint function and pain scores of the artificial femoral head replacement group in the early and follow-up periods are better than those of the PFNA group. The artificial femoral head replacement is more suitable for the treatment of elderly unstable intertrochanteric fractures.

人性话语在新世纪文学和批评中出现碎片化与泛一体化的嬗变。在文化内涵上,从"私人的文学"到"人民的文学",言说方式从"人性"转向"人民性"。创作与批评中的人性话语在断裂语境中呈现分化与弥合的特征。从哲学本质来看,人性话语的感觉化与自我化的思维出现分离,转变为开放性与封闭性的矛盾和吊诡。从价值取向来看,人性话语阐释的有效性与合法性受到质疑,在被否定和自我否定中得到一定程度的自我修复,构建了新的人性价值体系。

江飞首先是青年学者,其次是文学评论家,同时还是作家。然而,在社会分工日益精细化和高效化的当下,学者、作家、评论家等因角色定位的不同和专业领域的差别而出现了分化的现象。但在文学批评已然走向学院化的背景中,三者的身份界限又在很大程度上模糊化了。正因如此,江飞并不满足于只当知识型的学者或者技术型的专才,而是将上述三重身份加以贯通而进入超越之境,并游刃有余地发挥着多重身份融合所带来的独特优势。
