Discrete-time queues are infinite dimensional switches in time. Ever since Shannon published his paper ("Memory requirements in telephone exchange," Bell Syst. Tech. J., pp. 343-349, vol. 29, 1950) on the memory requirements in a telephone exchange, there have been tremendous efforts in the search for switches with minimum complexity. Constructing queues(More)
Background. Based on epidemiological data, clinical trials, and meta-analytic reviews, omega-3 polyunsaturated fatty acids (n-3 PUFAs) seem to be a biological link between depression and cardiovascular diseases (CVDs). Presentation. Involvement of n-3 PUFAs in depression and CVDs may be associated with a chronic, low-grade, inflammation. We hypothesize that(More)
The purpose of extractive summarization is to automatically select a number of indicative sentences, passages, or paragraphs from the original document according to a target summarization ratio and then sequence them to form a concise summary. In the paper, we proposed the use of probabilistic latent topical information for extractive summarization of(More)
We present a multi-instance object segmentation algorithm to tackle occlusions. As an object is split into two parts by an occluder, it is nearly impossible to group the two separate regions into an instance by purely bottom-up schemes. To address this problem, we propose to incorporate top-down category specific reasoning and shape prediction through(More)
The epidermal growth factor receptor (EGFR)/RAS/RAF/MEK/MAPK pathway is an important pathway in the carcinogenesis, invasion and metastasis of colorectal cancers (CRCs). We conducted a retrospective study to determine the prognostic values of EGFR expression and KRAS mutation in patients with metastatic CRC (mCRC) based on synchronous or metachronous(More)
BACKGROUND Areca nut chewing has been reported to be associated with obesity, metabolic syndrome, hypertension, and cardiovascular mortality in previous studies. The aim of this study was to examine whether chewing areca nut increases the risk of coronary artery disease (CAD) in Taiwanese men. METHODS This study is a hospital-based case-control study. The(More)
—In this paper, we consider extractive summarization of broadcast news speech and propose a unified probabilistic gen-erative framework that combines the sentence generative probability and the sentence prior probability for sentence ranking. Each sentence of a spoken document to be summarized is treated as a probabilistic generative model for predicting(More)
— Queueing theory is generally known as the theory to study the performance of queues. In this paper, we are interested in another aspect of queueing theory, the theory to construct queues via switched delay lines. We consider three types of discrete-time queues: linear compressors, non-overtaking delay lines and flexible delay lines. These three types of(More)
— In this paper, we study the problem of exact emu-lation of two types of optical queues: (i) N-to-1 output-buffered multiplexers with variable length bursts, and (ii) N × N output-buffered switches with variable length bursts. For both queues, the delay of a packet is known upon its arrival. As such, one can emulate such queues by finding a delay path that(More)
