Pulsar Signal of Deconfinement
A solitary millisecond pulsar, if near the mass limit, and undergoing a phase
transition, either first or second order, provided the transition is to a
substantially more compressible phase, will emit a blatantly obvious
signal---spontaneous spin-up. Normally a pulsar spins down by angular momentum
loss to radiation. The signal is trivial to detect and is estimated to be
``on'' for 1/50 of the spin-down era of millisecond pulsars. Presently about 25
solitary millisecond pulsars are known. The phenomenon is analogous to
``backbending'' observed in high spin nuclei in the 1970's.Comment: 12 pages, 11 figures, Latex-espcrc1.sty (Dec. 1997, Plenary Talk to

Discipline-specific reading expectation and challenges for ESL learners in US universities
English-medium institutions of higher education host increasing numbers of English-as-a second-language (ESL) learners in the US. English language skill is vital to their progress. Previous research examined reading challenges and expectations faculty have for their first-year students within five popular majors for international students including Biology, Business, Computer Science, Engineering, and Psychology. Analyses revealed differences across majors and identified the reading expectations and challenges these first-year learners face. Building on the research, this study examines the reading expectations of faculty for their upper-division students nearing graduation. In addition to comparing the reading expectations and challenges within the same five majors, we compared professor perceptions across the baccalaureate experience. We present these findings along with observations of participating faculty across the five majors regarding the linguistic preparation of their students for professional work or graduate study within the discipline. The implications and applications of these findings are discussed
Enhanced proportional-derivative control of a micro quadcopter
ABSTRACT This paper studies the design of an enhanced proportionalderivative (PD) controller to improve the transient response of a micro quadrotor helicopter (quadcopter Introduction Micro aerial vehicles (MAVs) have a wingspan less than 0.15 m and a mass less than 0.1 kg The control of quadcopters has mostly been focused on ma

Conservation plans for the northern spotted owl and other forest management proposals in Oregon : the economics of changing timber availability
The goal of this study is to analyze how the ISC Conservation Strategy may influence Oregon's timber availability and economy in the context of overall changes in public land management. Two themes are important: first, how the state's future will differ from today and second, how the state's future will be affected by reductions from recently observed harvest levels.
This report summarizes the history of timber harvests in Oregon, the role of the timber industry in Oregon's economy, and the implications of changing timber availability for (1) Oregon's forest land allocation, (2) Oregon's harvests by owner and region, (3) Oregon's state economy in terms of jobs and payrolls in timber industries and other sectors of the economy, receipts to local governments, and regional timber product prices, and (4) Oregon's communities in terms of jobs, wage and salary income, receipts to local governments, and potential dislocation of local citizens.Gerald W.
