Given the extensive study of clock skew minimization, in the ISPD 2009 Clock Network Synthesis (CNS) Contest, clock latency range (CLR) was initially minimized across multiple supply voltages under capacitance and slew constraints. CLR approximates the summation of the clock skew and the maximum source-to-sink delay variation for multiple supply voltages.(More)
BACKGROUND Human papillomavirus (HPV) persistence is the pivotal event in cervical carcinogenesis. We followed a large-scale community-based cohort for 16 years to investigate the role of genotype-specific HPV persistence in predicting cervical cancer including invasive and in situ carcinoma. METHODS At the baseline examination in 1991-1992, 11,923(More)
Human papillomavirus (HPV) 52 and 58 are oncogenic HPV types prevalent in Asia. Our study aims to explore intratypic variants of HPV 52 and 58 in Taiwan. A total of 11,923 women were enrolled from seven townships in 1991-1992. HPV DNA in their cervical cells was detected and typed by EasyChip® HPV blot. Among 424 participants infected with HPV 52 and/or 58,(More)
OBJECTIVES To investigate the prevalence at live birth of congenital heart disease (CHD) in Taiwan. STUDY DESIGN Patients with CHD born from 2000 to 2006 were identified from National Health Insurance databases. RESULTS CHD prevalence was 13.08 per 1000 live births: 12.05 (simple, 10.53; severe, 1.51) in male infants and 14.21 (simple, 12.90; severe,(More)
BACKGROUND Concurrent with the recent rise of the incidence in obesity, nonalcoholic fatty liver disease is increasingly prevalent in childhood. The aim of this study was to identify non-invasive biomarkers for liver steatosis in obese children and adolescents. METHODS We used a cross-sectional study to examine risk factors for liver steatosis in obese(More)
OBJECTIVE To compare the epidemiological and economic impact of additional cross-protection against oncogenic human papillomavirus (HPV) types beyond 16/18 of the bivalent vaccine (BV) versus protection against nononcogenic HPV types 6/11 of the quadrivalent vaccine (QV) in Taiwan. METHODS A lifetime Markov model calibrated to the Taiwanese setting(More)
BACKGROUND Only a small proportion of women infected with human papillomavirus type 18 (HPV18) may progress to persistent infection and cervical neoplasia. This community-based cohort study aimed to assess associations with human leukocyte antigen (HLA) class II genotypes for natural infection of HPV18 and subsequent risk of cervical neoplasia. METHODS(More)
Human papillomavirus (HPV) causes cervical neoplasia; but limited data are available from Asia. We conducted a large-scale community-based cohort study in Taiwan to estimate prevalence of genotype-specific HPV infection and cervical neoplasia. Following written informed consent, cervical cells for cytology and HPV testing were collected from 11,923(More)
OBJECTIVE To compare the risk of respiratory syncytial virus (RSV)-associated hospitalization and analyze the epidemiology of RSV infection in patients with cyanotic and acyanotic congenital heart disease (CHD), we analyzed the nationwide health insurance database from 2005-2010. STUDY DESIGN This study included 1050 patients with cyanotic CHD and 7077(More)
A nested case-control study of invasive and in situ cervical cancer was performed within a community-based cohort of 13,595 Taiwanese women assembled in 1991, with a follow-up period of 9 years. Baseline serum or plasma samples were analysed for antibodies against human papillomavirus (HPV) types 6, 16 and 18 and Chlamydia trachomatis. In total, 114 cases(More)
