Conventional timescale modification methods have the problem that as the modification rate gets higher the timescale modified speech signal becomes less intelligible, because they ignore the effect of articulation rate on speech characteristics. In this paper, we propose a variable timescale modification method based on the knowledge that the timing(More)
— Network topology information helps one analyze faults in IP networks and their locations. Rectifying such faults is a key role of an enterprise IP network management system. Thus, the automatic discovery of enterprise network topology has been the subject of rigorous study for many years. This paper proposes a Simple Network Management Protocol(More)

PURPOSE Plasma lipoprotein-associated phospholipase A₂ (Lp-PLA₂) binds to low-density lipoprotein. The levels of Lp-PLA₂ reflect the plaque burden, and are upregulated in acute coronary syndrome (ACS). We investigated the diagnostic value of Lp-PLA2 levels and found that it might be a potential biomarker for ACS. MATERIALS AND METHODS We classified 226(More)
This paper represents a robust target signal detector using two microphones. Most of target signal detection (TSD) algorithms incorporate with microphone arrays (MAs), and their basic assumption is that the location of target acoustic source is known. Therefore, target signal portions can be identified by exploiting the spatial information of the target(More)
Spontaneous coronary artery dissection (SCAD) is a rare and occasionally life-threatening cause of acute coronary syndrome. Patients may present with clinical scenarios ranging from angina pectoris to cardiogenic shock to sudden cardiac death, and it may be a potentially life-threatening condition if not recognized. However, its etiology, pathophysiology(More)
