As process technology goes into deep submicron range, interconnect delay becomes dominant among overall system delay, occupying most of the system clock cycle time. Interconnect delay is now a crucial factor that needs to be considered even during high-level synthesis. In this paper, we propose a concurrent scheduling and binding algorithm that takes(More)
Interconnect delay should be considered together with computation delay during architectural synthesis in order to achieve timing closure in deep submicrometer technology. In this paper, we propose an architectural synthesis technique for <i>distributed-register architecture,</i> which separates interconnect delay for data transfer from component delay for(More)
In this paper, we propose a systematic pipelining method for a linear system to minimize power and maximize throughput, given a constraint on the number of pipeline stages and a set of resource constraints. The method first retimes operations such that as many operations as possible take common operands as their inputs, and then performs the operand sharing(More)
Providing multiple modes to support dynamically changing environments, standards, and new services is prevalent in embedded systems, especially in mobile radio systems. Because such a system frequently contains time-constrained tasks, it is important to analyze the temporal requirements as well as the functional correctness. This paper presents a method to(More)
OBJECTIVE To determine whether quantitative perfusion parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) correlate with immunohistochemical markers of angiogenesis in rectal cancer. MATERIALS AND METHODS Preoperative DCE-MRI was performed in 63 patients with rectal adenocarcinoma. Transendothelial volume transfer (K(trans) ) and(More)
The transplantation of neural precursor cells (NPCs) is known to be a promising approach to ameliorating behavioral deficits after stroke in a rodent model of middle cerebral artery occlusion (MCAo). Previous studies have shown that transplanted NPCs migrate toward the infarct region, survive and differentiate into mature neurons to some extent. However,(More)
Real-time planning and scheduling in a shop floor are not easy to accomplish due to the concurrent flow of various parts as well as sharing of different types of resources. Multi-pass scheduling is a well known method for solving the aforementioned problem. Its success depends largely on selecting the best decision-making rule fast and effectively. Although(More)
Perfluorocarbon nanoemulsions (PFCNEs) have recently been undergoing rigorous study to investigate their ability to improve the therapeutic efficacy of tumor ablation by high intensity focused ultrasound (HIFU). For precise control of PFCNE delivery and thermal ablation, their accumulation and distribution in a tumor should be quantitatively analyzed. Here,(More)
