Music via motion: transdomain mapping of motion and sound for interactive performances

This paper presents a framework called Music via Motion (MvM) designed for the transdomain mapping between physical movements of the performer(s) and multimedia events, translating activities from one creative domain to another-for example, from physical gesture to audio output. With a brief background of this domain and prototype designs, the paper describes a number of inter- and multidisciplinary collaborative works for interactive multimedia performances. These include a virtual musical instrument interface, exploring video-based tracking technology to provide an intuitive and nonintrusive musical interface, and sensor-based augmented instrument designs. The paper also describes a distributed multimedia-mapping server which allows multiplatform and multisensory integrations and presents a sample application which integrates a real-time face tracking system. Ongoing developments and plausible future explorations on stage augmentation with virtual and augmented realities as well as gesture analysis on the correlations of musical gesture and physical gesture are also discussed.     

An Extended Service Filtering Technique for Mass Calling-Type Services Using Intelligent Peripheral in an SCP-Bound Network

This paper proposes an extended service filtering technique to prevent overload in service control point (SCP) due to televoting (VOT) or mass calling (MAS) services with the heavy traffic characteristics. Also, this paper compares this extended technique with the existing overload control techniques, and calculates steady state call blocking probabilities in intelligent network (IN) under overload conditions. The proposed technique considers SCP overload and IN Capability Set (CS)-1 services (such as VOT or MAS service) that have to use the specialized resources of intelligent peripheral (IP). This technique uses first an activating step in which SCP requests service filtering to service switching point (SSP). Then, in the filtering step, SSP sends filtering results to SCP periodically or each Ncalls. Also, when filtering time-out expires, SSP stops service filtering, and sends service filtering response to SCP in the deactivating step. This paper applies this technique to VOT/MAS service, and calculates SCP and SSP-IP (circuit) call blocking probabilities by using an analytical VOT/MAS service model. With the modeling and analyzing of this new technique, it shows that this technique reduces the traffic flow into SCP from SSP and IP prominently.

一种两步判决的说话人分割算法

为了提高说话人分割(SS)准确率,该文综合考虑了静音信息和性别信息在SS中的作用,提出了一种两步判决的SS算法。在从音频流中分离出语音段的基础上,采用两步判决的方法进行SS。第1步采用基频信息为主、性别模型为辅的策略进行SS,将相邻说话人基频差异大的说话人改变检测出来;第2步采用基于性别的改进T2判决公式进行SS,实现相邻说话人基频差异小的同性别SS,为此,该文提出了一个基于块的潜在说话人改变点检测算法。实验结果表明,本文算法提高了分割准确率,F1度量值可达85.14%。对于短时长(2 s)语音段的SS,该算法和传统的贝叶斯信息判决算法相比,漏检率减少了16%。     

A Versatile Platform for the Tumor-Targeted Intracellular Delivery of Peptides,Proteins, and siRNA

The efficient delivery of biologics into cells provide unique opportunities to modulate intracellular targets not druggable by conventional small molecules. The supercharged polypeptide (SCP) has become a novel intracellular delivery system due to their special advantages, including enhanced delivery efficiency and serum tolerance. However, owing to their cationic charge and non-specificity characteristics, the in vivo application of SCP is limited. Here, an activatable SCP (ASCP) with a pH-sensitive charge shielding sequence (CSS), a protease cleavage site, and SCP are engineered. This system shows the potential to reduce the non-specific binding and effectively deliver various cargo (peptide, protein, small molecule, and siRNA) into the cytosol not only in vitro but also in vivo. Furthermore, an ASCP fusion protein is designed to co-delivery of peptide (KLA)/siRNA (IKBKE) with different tumorigenesis pathways to triple negative breast cancer (TNBC) for optimal therapeutic outcomes. It is believed that ASCP delivery system will facilitate the development of bioactive molecules for use against intracellular targets. This simple yet versatile delivery system can also pave the way for the co-delivery of multiple therapeutic cargos to address the emerging needs of combination cancer therapy.
