NFT数字艺术品作为一种新生事物,其交易十分火爆,但其中铸造者、购买者和NFT交易平台都存在不同程度的侵权风险。NFT数字艺术品实现交易流通的底层逻辑在于区块链加智能合约的组合。对于NFT数字艺术品的法律定性,“物权说”“债权说”“加密数字凭证说”等学说各行其道,但“物权说”无法对“物权法定”的基本原则进行解释,“债权说”过度关注智能合约在NFT数字艺术品交易过程发挥的“合同”作用,忽视了持有者获得的是一项财产性权益。而“加密数字凭证说”难以涵摄NFT数字艺术品价值性和可交易性的基本属性。NFT数字艺术品无法满足独创性的要求,故非《著作权法》意义上的作品,因而应当被认定为网络虚拟财产。由于NFT数字艺术品铸造及交易便利且侵权成本低,加之“避风港”规则的失灵,铸造者在铸造以及后续交易中可能因未获取原艺术品著作权人授权许可而侵犯其复制权、信息网络传播权,购买者也会因购买侵权NFT后在平台上展示而涉嫌侵犯信息网络传播权,而交易平台则可能因未尽到必要的注意义务而承担帮助侵权责任。要改善NFT数字艺术品交易领域的著作权侵权乱象,需要从不同角度出发,构建侵权监测和侵权举报系统,做好内容监管;以注意义务限制“避风港”规则的滥用,促进交易合规;完善NFT数字艺术品著作权侵权的救济路径,避免损失扩大。

The US GAAP is believed to be the best and most comprehensive set of accounting standards in the world. However, the Enron scandal has made the world reconsider it. According to research reports by the US SEC and FASB, principle-based accounting standards should be adopted in the US. But which is better, a GAAP based on principles or on rules? By considering the shift from a rule-based accounting standard to a principle-based one on bad debt provisions in China, this paper examines the association between earnings management and types of accounting standards. We find that listed firms are more likely to manage earnings with discretion under principle-based accounting standards, while rule-based accounting standards limit firms' earnings management behaviour.

Uncontrolled microglial activation is decisively involved in the neuroinflammatory pathogenesis of brain diseases. Consequently, suppression of microglial overactivation appears to be a strategy for the prevention of nerve injury. In this paper, a novel vanadium complex, vanadyl N-(p-N,Ndimethylaminophenylcarbamoylmethyl)iminodiacetate(VO(p-dmada)), was synthesized from vanadyl sulfate and N,N-dimethyl-p-phenylenediamine, which was structurally characterized by Fourier transform infrared spectrum and ESI-MS analysis. The effect of VO(p-dmada) on neuroinflammation was investigated by using the models of lipopolysaccharide(LPS)-induced BV2 microglial cells and BALB/c *** data demonstrated that VO(p-dmada) significantly suppressed microglial activation by downregulating inflammatory mediators and associated proteins, and inactivating nuclear factor-κ B(NF-κ B) signaling pathway. VO(p-dmada) also upregulated peroxisome proliferator activated receptor gamma(PPARγ) by reducing transglutaminase 2 and heat shock protein 60 expression. Co-treatment with PPARγ antagonist GW9662 significantly impeded the inhibitory effect of VO(p-dmada) on LPS-induced *** cumulative findings demonstrated that VO(p-dmada) is a potential new drug for the treatment of neuroinflammation-related neurodegenerative diseases.

采用不同比例的麸皮和发酵青草等生物质材料耦合黑臭水体疏浚底泥进行好氧堆肥中试试验。针对实际工程产生的疏浚底泥,探究适宜比例的调理剂投加配比。设置不同物料配比的对照组2组(CK0、CK1)、试验组5组(T1—T5)进行中试试验,通过理化性质、种子发芽率等指标检测揭示不同原料配比对底泥好氧堆肥过程中堆肥性能的影响。结果表明:堆肥初期,含水率控制在50%左右,C/N控制在25~35,1 d后各堆体温度均超过50℃,各组高温期(温度>55℃)维持时间超过5 d,均符合HJ 1266—2022《生物质废物堆肥污染控制技术规范》标准要求。堆肥过程中,堆体升温速率和最高温度随着生物质材料添加量的增加呈递增趋势,其中T1和T2组的最高温度均超过70℃并维持24 h以上,这证明将麸皮和发酵青草2种生物质材料按适宜比例混合作为调理剂能够促进堆体快速发酵;堆肥结束后,各组挥发分含量稳定在20%~30%,含水率为7%~16%,pH值为8.15~8.30,各组种子发芽指数(GI)均>140%。其中,T2组固氮作用最显著、堆肥品质最优。因此,在实际生产中,按m(疏浚底泥)∶m(发酵青草)∶m(麸皮)=400∶125∶125进行好氧发酵堆肥,可显著降低物料生物毒性并产生高肥效种植土。

与装配在主干电网的同步相量单元(phasor measurement unit,PMU)相比,配电网PMU在进行频率测量时,除了无法利用对称的三相信号之外,还面临更高强度谐波和噪声的干扰。该文针对配电网PMU测量具体特点,研究低通数字微分滤波器的优化设计,通过对单相信号相位进行滤波实现频率测量。优化设计目标是,在低频段获得高精确度微分运算频响特性同时,强化中高频段对相位误差中各次谐波的有效抑制,并最小化噪声增益。通过对含约束优化问题求解,实现了长度为1.0~1.5工频周期的线性相位有限冲激响应(finite impulse response,FIR)数字微分器设计。仿真结果表明,所设计滤波器与IEEEC37.118.1相量测量参考算法配合,可以在静态和动态配电网环境下实现频率的快速精确测量,具有较高的工程应用价值。
