A total of 403 healthy, premenopausal women, residing near Santa Clara, California, were recruited from a large health care plan in California for a study of menstrual function. After a telephone interview, participants collected daily urine samples and recorded bleeding and other information in diaries. Data were collected during 1990-1991. Urine samples were analyzed for creatinine and for es...

a watershed management program is usually based on the results of watershed modeling. accurate modeling results are decided by the appropriate parameters and input data. precipitation is the most important input for watershed modeling. precipitation characteristics usually exhibit significant spatial variation, even within small watersheds. therefore, properly describing the spatial variation o...

The absolute frequency of the length standard at 514.67 nm based on the molecular iodine ( I2) transition of the P(13) 43-0 component a3 is measured using a self-referenced femtosecond optical comb. This frequency-based technique improves measurement precision more than 100 times compared with previous wavelength-based results. Powerand pressure-related frequency shifts have been carefully stud...

Computation of pairs of analysis and synthesis (dual) windows is very important in using discrete-time Gabor transform. Biorthogonal-like sequence theory ooers some simple solutions for computing dual windows for signal representation. Solutions to the biorthogonal-like condition are obtained by dividing the problem into various cases. As an example, dual windows for the truncated Gaussian wind...

Due to increase in MOS scaling, frequency and bandwidth of high performance CMOS VLSI circuits, on-chip consumed power is enhanced. It creates an important role in both switching and dc power dissipation. This dissipated power is usually rehabilitated into degenerated heat, affecting the performance and consistency of a chip. In this paper we contribute: an algorithm for thermal bound placement...

Three experiments compared younger (mean age was 23.7years) and older (mean age was 72.1years) observers' ability to visually discriminate line length using both explicit and implicit standard stimuli. In Experiment 1, the method of constant stimuli (with an explicit standard) was used to determine difference thresholds, whereas the method of single stimuli (where the knowledge of the standard ...

HYPOTHESIS Current techniques for open conventional thyroidectomy or parathyroidectomy have evolved to enable a shorter incision (main proposition), and the length of the incision is influenced by objective factors. DESIGN Case series. SETTING University referral center. PATIENTS AND INTERVENTION Retrospective study of the most recent 200 primary consecutive routine thyroid and parathyroi...

PURPOSE To investigate the effect of axial length (AL) on the structure-function relationship between retinal nerve fiber layer (RNFL) thickness measurements and visual field (VF) sensitivity measured with Goldmann III and V. METHOD There were 85 eyes of 85 patients with primary open angle glaucoma included in the current study. Optical coherence tomography and VF (Humphrey Field Analyzer 24-...
