Modern CPUs are operating faster than ever because to the quick development of integrated circuits. On hardware, FIFO frequently acts as the buffer for data transmission and reception. In order to transfer data across systems with various time domains quickly and simply, asynchronous FIFOs can solve a variety of clock domain difficulties. However, stable operation of the system requires adjustment of the clock periods. This paper focuses on making the use of two '2 D Flip flop' as synchroniser to avoid the metastability conditions in the design. Universal gates and status flags have been introduced with Gray Code to increase the speed and efficiency of FIFO. It is anticipated that this paper will serve as a resource for IC designers when they are creating interface circuits and helpful in real time applications as it happens on own time and doesn't need scheduling includes emails, company newsletter, chatting on Slack, and Asana and Trello boards. The results have been verified using the software Xilinx Vivado that the proposed asynchronous design is relatively faster, accurate and consumes relatively lesser power while maintaining comparable performance in terms of delays and metastability. The design presented here is for a 16-bytes FIFO memory which can be modified further as per the memory required. © 2024 IEEE.

Atomically thin 2D films and their van der Waals heterostructures have demonstrated immense potential for breakthroughs and innovations in science and technology. Integrating 2D films into electronics and optoelectronics devices and their applications in electronics and optoelectronics can lead to improve device efficiencies and tunability. Consequently, there has been steady progress in large-area 2D films for both front- and back-end technologies, with a keen interest in optimizing different growth and synthetic techniques. Parallelly, a significant amount of attention has been directed toward efficient transfer techniques of 2D films on different substrates. Current methods for synthesizing 2D films often involve high-temperature synthesis, precursors, and growth stimulants with highly chemical reactivity. This limitation hinders the widespread applications of 2D films. As a result, reports concerning transfer strategies of 2D films from bare substrates to target substrates have proliferated, showcasing varying degrees of cleanliness, surface damage, and material uniformity. This review aims to evaluate, discuss, and provide an overview of the most advanced transfer methods to date, encompassing wet, dry, and quasi-dry transfer methods. The processes, mechanisms, and pros and cons of each transfer method are critically summarized. Furthermore, we discuss the feasibility of these 2D film transfer methods, concerning their applications in devices and various technology platforms. © 2024 The Authors.

Cluster-preserving sampling algorithm for large-scale graphs

Science China(Information Sciences) 2023年第1期66卷 60-76页

Graph sampling is a very effective method to deal with scalability issues when analyzing largescale graphs. Lots of sampling algorithms have been proposed, and sampling qualities have been quantified using explicit properties(e.g., degree distribution) of the sample. However, the existing sampling techniques are inadequate for the current sampling task: sampling the clustering structure, which is a crucial property of the current networks. In this paper, using different expansion strategies, two novel top-leader sampling methods(i.e., TLS-e and TLS-i) are proposed to obtain representative samples, and they are capable of effectively preserving the clustering structure. The rationale behind them is to select top-leader nodes of most clusters into the sample and then heuristically incorporate peripheral nodes into the sample using specific expansion strategies. Extensive experiments are conducted to investigate how well sampling techniques preserve the clustering structure of graphs. Our empirical results show that the proposed sampling algorithms can preserve the population's clustering structure well and provide feasible solutions to sample the clustering structure from large-scale graphs.

Monoclonal antibodies, secreted by a single clone of B cells, possess excellent specificity and high sensitivity. Due to their outstanding advantages, the monoclonal antibody market is overgrowing. Currently, the preparation of monoclonal antibodies mainly relies on hybridoma technology, which preserves the biological activity and increases the antibody yield. However, the time-consuming cell screening and low throughput in hybridoma technology greatly limit the antibody screening process. In this study, a microfluidic chip for antibody functional screening was developed by combining hybridoma technology with single-cell technology. The microarraybased approach significantly improved the screening throughput and reduced the screening time. © 2024 Copyright held by the owner/author(s).

Monoclonal antibodies(mAb), currently the largest category of biopharmaceuticals, are widely used due to their high specificity and low side effects. The main method for producing monoclonal antibodies is hybridoma technology, which involves the fusion of B cells with myeloma cells and a series of screening steps to obtain hybridoma cells with good functional activity. However, traditional cell screening methods have limitations such as long cycle times, low throughput, and high cost. In this study, a microfluidic chip was invented that enables affinity screening and functional activity screening of monoclonal antibodies based on hybridoma cells. This chip significantly reduces screening time, improves cell handling throughput, and reduces costs. © 2024 Copyright held by the owner/author(s).
