Trading silence, defined as unusually low trading activity, before anticipated firm information events, is an important capital market phenomenon which hampers price discovery. Using unique data on firm-level cryptocurrency holdings extracted from the SEC filings, we find that silence quarterly earnings announcements intensifies after a firm's initial adoption of cryptocurrency. Moreover, this effect stronger for subsample firms reporting losses. Our findings are robust to endogenous concern...
Spatial crowdsourcing is an effective and novel method. In systems, a centralized platform traditionally used to allocate tasks select workers. Centralized platforms always face following challenges: 1) How ensure the rationality of allocating; 2) payments workers in system when dishonest requesters exist; 3) maximum number are assigned. 4) integrity reliability platform. To solve these problems, this article proposed distributed blockchain-based framework - TSWCrowd (Task Select Worker...
Efficient Indexing is a key us content-based video retrieval solutions. In this paper we represent sequences as traces via scaling and linear transformation of the frame luminance field. Then an appropriate lower dimensional subspace identified for trace indexing. We also develop geometry matching algorithm based on average projection distance with locally embedded metric. Simulation results demonstrated high accuracy very fast speed proposed solution
With the phenomenal growth of online and personal video repositories, an efficient robust example-based search solution is required to support applications like query by clip, capture, repeated clip detection. In this letter, sequences are represented as temporal trajectories via scaling lower dimensional representation frame luminance field, a trajectory indexing matching scheme developed search. Simulation results demonstrate that proposed approach achieves excellent performance in both...
The complex wavelet transform modulus maximum of the PD signal increases with scale, while white noise decreases scale. According to characteristics, a study on suppression using effective coefficient (ECWC) threshold method is launched in this paper and comparison conducted denoising selection Stein unbiased risk estimate theory minimax theory. results show that ECWC more distortion extract lower compared other method.
To investigate the steady state disposition and action of racemic propafenone its enantiomers potential for an enatiomer‐enantiomer interaction in Chinese subjects. Eight healthy male individuals received a double‐blind, randomized, cross‐over study (150 mg every 6 h), (S)‐, (R)‐propafenone each h) placebo orally 4 days. During last dosing interval plasma concentrations both were measured ECG, blood pressure (MAP) heart rate monitored. Whereas apparent elimination half‐life (t ½,z ), mean...
摘要: 该文研究了衰落信道中基于译码－转发的多中继合作分集系统的功率分配问题。假设源节点有完全的信道状态信息，在总功率一定的条件下，以最小化系统的中断(outage)概率为目标，给出了如何选择中继节点以及如何在源节点和所选中继节点之间进行功率分配的算法。通过在任何时候最大化系统的瞬时容量来最小化系统的中断概率。仿真结果表明，该文提出的算法性能优于平均分配功率时系统的性能。 关键词: 无线通信;发射分集;合作分集;功率分配
