Three experiments explored preschoolers' and adults' understanding of the distinctive semantic functions of adjectives (i.e., to name properties) and count nouns (i.e., to name object kinds). In Experiment 1, we modeled a familiar adjective (e.g., "blue") syntactically as either an adjective (e.g., "This is a blue one") or a count noun (e.g., "This is a(More)
Head and neck cancers are a cause of morbidity and mortality throughout the United States. For low-income, African American men they are one of the leading causes of excess cancer deaths: although all racial/ethnic groups suffer from these cancers, African American men disproportionately suffer and die from them. Low-income communities have increased risks(More)
Design trade-offs for a low-voltage two-stage amplifier in the HP CMOS14 process are presented and some of the issues of low-voltage analog design are discussed. The design of a new constant-transconductance input stage that has a rail-to-rail common-mode input range is described, along with the rail-to-rail class-AB output stage. The performance(More)
A cross-sectional study was conducted with 50 African American head and neck cancer survivors. Common coping strategies were identified and examined in relation with quality of life and relationship well-being. Coping through support from God, seeking emotional support from family and friends, and helping others were the most commonly used strategies.(More)
Head and neck cancer is the ninth most common cancer in the USA, accounting for 3.3 % of all cancers. The incidence of head and neck cancer has plateaued recently; however, morbidity and mortality continue to remain high. Moreover, racial disparity between African-American and White patients has been studied in the head and neck community, and a vast(More)
Multiple factors contribute to disparities in head and neck cancer prevalence across the sociodemographic spectrum, including a lack of screening efforts in mostly underserved minority communities. African Americans and other ethnic minorities are at greater risk for late-stage diagnoses due to the lack of routine screenings and examinations. Advanced stage(More)
A low-jitter charge-pump PLL is built in 90-nm CMOS for 1-10 Gb/s SerDes transmitter clocking. The PLL employs a programmable dual-path loop filter with integrating path and novel resistorless proportional path that can be independently controlled and accurately modeled for flexible setting of closed-loop bandwidth and peaking. Frequency is synthesized(More)
