由于具有宽容量范围、高工作电压、轻质、性能可靠等优点,聚合物基的电介质薄膜电容器等在现代电子学中具有重要作用。通常所研究的介电聚合物和填料都是不可生物降解的,这是产生电子废物污染的原因之一。为了解决这个问题,本研究选择了可生物降解的聚酯PBAT作为基体,将其分别与两种自制的生物质衍生填料复合,制备了可生物降解的聚合物基电介质复合材料。论文主要分为以下几个主要内容:首先,以香蕉皮废弃物（BP-W）为原料,通过热解的方法,分别制备了N掺杂和非掺杂的生物质炭,N掺杂技术解决了非掺杂生物炭性能上的一些缺陷,通过透射电子显微镜（TEM）、X射线衍射（XRD）、能量色散X射线分析（EDX）、X射线光电子能谱（XPS）、傅里叶变换红外光谱（FTIR）和热重分析（TGA）等手段对产物进行了系统表征,结果证实了氮的成功掺杂。并将它们作为含碳导电有机填料分别与PBAT复合制备了复合电介质材料,掺杂N生物炭可以改善聚合物复合材料的介电性能和热稳定性,而不会牺牲力学性能和生物降解性。具体而言,含有10 wt.%N掺杂生物炭的PBAT纳米复合材料的介电常数为10.64,比纯PBAT（介电常数为5.85）增加了83%。此外,复合材料介电损耗在1000 Hz时保持在0.071以下。其次,通过对生物质废料牛骨头的热解,制备了羟基磷灰石（HAp）并将其作为陶瓷无机填料,对其进行了系统的表征。随后,利用溶液共混和热压技术制备了包含HAp和PBAT的可生物降解介电复合材料,并进行了系统的表征。结果表明了单相结晶HAp的成功制备,具有良好定义的晶界,所得到的可生物降解复合材料表现出显著的介电性能,包括高介电常数、低介电损耗和良好的低填料含量下的击穿强度。介电常数随着填料含量的增加而增加,而介电损耗保持低水平,击穿强度随着填料含量的增加而略有降低。能量储存密度的理论研究表明,PBAT/HAp-3%复合材料具有较高的能量储存密度(Ust=3.56 J/cm3),比纯PBAT(Ust=2.48J/cm3)高出43.55%。HAp/PBAT复合材料的力学性能和热稳定性均得到了不同程度的提升。此外,对两个体系的复合材料生物降解性能进行了分析,评估了介电复合材料的生物降解行为,包括在不同时间段内浸泡在谷胱甘肽溶液中以模拟酶降解。评估参数包括重量损失率、力学性能和外观检查等。对完全可生物降解的PBAT/绿色填料复合材料的生物降解性能进行了全面的评价。

猪圆环病毒2型(Porcine Circovirus type 2,PCV2)衣壳(Capsid)蛋白是制备抗猪圆环2型病毒亚单位疫苗的有效免疫抗原,能在大肠杆菌及杆状病毒/昆虫细胞表达系统中获得表达,然而在哺乳细胞中的表达研究仍然缺乏。瞬时表达条件考察结果显示,采用宿主HEK293F细胞及PEI-40kDa转染试剂能获得35%病毒PCV2 Capsid基因细胞转染效率。转染试剂PEI(Polyethylenimine)与DNA比例差异会影响复合物形成大小及形态,复合物形成15~80 nm颗粒有利于转染效率的提高。实验以免疫逃逸型猪圆环病毒2b型NDSU41513病毒株,设计了新型PCV2 Capsid (△1-41aa)-Fc(pig) protein(PCFP)分子。在3 L反应器中成功实现了HEK293F细胞瞬时表达PCFP,表达水平达到3.8 mg/L。PCFP蛋白能够自主装形成约为41 nm类病毒颗粒,诱导小鼠机体内产生强烈的体液免疫反应,具有很高的应用潜力。

Dear Editor,In the era of big data and artificial intelligence,"smart breeding"has become a broad conceptual framework encompassing the paradigm shift of crop breeding to relying on analysis of high-throughput population genetics and phenomics data to conduct genomic selection,allowing identification and optimal use of the genetic potential in crop species(Xiao et al.,2022;Xu et al.,2022;Wang et al.,2023).Most existing tools for analyzing high-throughput breeding data require extensive computational power,complex installation processes,and command-line expertise and are therefore challenging and inconvenient for the majority of researchers and breeders(Brandies and Hogg,2021).

Evaluating Privacy Leakage and Memorization Attacks on Large Language Models (LLMs) in Generative AI Applications

引用

Journal of Software Engineering and Applications 2024年第5期17卷 421-447页

作者： Harshvardhan Aditya Siddansh Chawla Gunika Dhingra Parijat Rai Saumil Sood Tanmay Singh Zeba mohsin Wase Arshdeep Bahga Vijay K. Madisetti School of Computer Science Engineering & Technology Bennett University Greater Noida India Cloudemy Technology Labs Chandigarh India School of Cybersecurity and Privacy Georgia Institute of Technology Atlanta USA

The recent interest in the deployment of Generative AI applications that use large language models (LLMs) has brought to the forefront significant privacy concerns, notably the leakage of Personally Identifiable Information (PII) and other confidential or protected information that may have been memorized during training, specifically during a fine-tuning or customization process. We describe different black-box attacks from potential adversaries and study their impact on the amount and type of information that may be recovered from commonly used and deployed LLMs. Our research investigates the relationship between PII leakage, memorization, and factors such as model size, architecture, and the nature of attacks employed. The study utilizes two broad categories of attacks: PII leakage-focused attacks (auto-completion and extraction attacks) and memorization-focused attacks (various membership inference attacks). The findings from these investigations are quantified using an array of evaluative metrics, providing a detailed understanding of LLM vulnerabilities and the effectiveness of different attacks.
