For more than two decades rudimentary versions of the fixed sample and sequential search strategies have provided the primary theoretical foundation for the study of mate choice decisions by searchers. The theory that surrounds these models has expanded markedly over this time period. In this paper, we review and extend results derived from these models, with a focus on the empirical analysis of searcher behavior. The basic models are impractical for empirical purposes because they rely on the as- sumption that searchers--and, for applied purposes, researchers--assess prospective mates based on their quality, the fitness consequences of mate choice decisions. Here we expound versions of the models that are more empirically useful, reformulated to reflect decisions based on male phenotypic characters. For some organisms, it may be possible to use preference functions to de- rive predictions from the reformulated models and thereby avoid difficulties associated with the measurement of male quality per se. But predictions derived from the two models are difficult to differentiate empirically, regardless of how the models are formu- lated. Here we develop ideas that illustrate how this goal might be accomplished. In addition, we clarify how the variability of male quality should be evaluated and we extend what is known about how this variability influences searcher behavior under each model. more general difficulties associated with the empirical study of mate choice decisions by searchers are also discussed [Current Zoology 59 （2）： 184-199, 2013].

Background: Estrogens produce several beneficial effects upon the cardiovascular system. Amongst these, an endothelium-independent effect has been convincingly demonstrated only in vitro, while there is no evidence for such an effect in vivo. The aim of the present study was to evaluate the effect of acute administration of estradiol 17β upon coronary artery reactivity to methylergometrine in 16 menopausal patients with coronary artery disease. methods: Sixteen menopausal patients underwent coronary angiography at rest and after incremental doses of methylergometrine(intracoronary 2, 10, 30 μ g) before and 20 min after either intracoronary estradiol 17β (20 ng/mL at 1 mL/min for 20 min; 8 patients) or placebo(Dextrose 5% , 1 mL/min; 8 patients). Results and conclusions: No significant differences were observed in baseline coronary artery diameter or area between the 2 groups. No significant differences in the degree of coronary artery constriction were observed after either estradiol 17β or placebo at submaximal doses of methylergometrine. However, the degree of coronary artery constriction after maximal doses of methylergometrine was significantly attenuated by estradiol 17β compared to placebo(change in diameter:- 0.9± 4.5% vs.- 19± 6% , pwing methylergometrine administration in menopausal patients with coronary artery disease. This effect may be related to the calcium-antagonist properties of the ovarian hormone. Condensed The effect of acute administration of estradiol 17β upon coronary artery reactivity to methylergometrine was evaluated by coronary angiography in 16menopausalwomen with CAD. The investigation was performed at rest and after incremental dose of methylergometrine before and 20 min after either intracoronary estradiol 17β or placebo. Significant differences were not observed either in the baseline coronary artery diameter or the ar

A mobile incoherent Doppler lidar system has been experimentally demonstrated to be able to transmit reliable single frequency operation laser pulse, even after truck transit and in very high vibration environments. The linewidth of the injection-seeded pulse Nd:YAG laser can be measured by means of an I2 molecular filter. And, lidar validation experiments demonstrated the feasibility and capability of measuring wind field by the mie-Rayleigh Doppler wind lidar. The un-certainty of measured wind speed is 0.985m/s in the altitude range from 2 to 4 km.

Purpose: To compare lid-induced changes in corneal optics following reading, microscopy and computer work. methods: Nine subjects with normal ocular health were recruited for the study. Five subjects were myopic, two were emmetropic, one was astigmatic and one was hyperopic. Corneal topography was measured before and after 60 mins of reading a novel, performing a blood cell counting task on a microscope and Internet searching. Corneal topography data were used to derive the corneal wavefront Zernike coefficients up to the fourth order. A meridian analysis of instantaneous corneal power along the upper 90- degree semi-meridian was performed to examine local changes caused by eyelid pressure. Digital photography was used to capture body posture and eyelid position during the tasks. Results: Each of the three tasks showed systematically different effects on both the characteristics and location of corneal topography changes. Reading and microscopy generally exhibited larger and more centrally located changes compared with the computer task. Differences in wavefront aberration characteristics between the three tasks were apparent in both lower and higher order aberrations. The location of corneal distortions differed significantly between microscopy and computer work, with microscopy causing distortions to occur closer to the videokeratoscope measurement axis compared with computer work (p=0.015). Conclusions: Reading, microscopy and computer work have different effects on corneal aberrations. The results are in agreement with the hypothesis that lidinduced corneal aberrations may play a role in myopia development.

The sensitivity of snowpack sublimation estimates to instrument and measurement uncertainty perturbed in a monte Carlo fram.w.rk

The bulk aerodynamic flux equation is often used to estimate snowpack sublimation since it requires meteorological measurements at only one height above the snow surface. However, to date the uncertainty of these estimates and the individual input variables and input parameters uncertainty have not been quantified. we modeled sublimation for three (average snowpack in 2005, deep snowpack in 2011, and shallow snowpack in 2012) different water years (October 1 to September 30) at west Glacier Lake watershed within the Glacier Lakes Ecosystem Experiments Site in *** performed a monte Carlo analysis to evaluate the sensitivity of modeled sublimation to uncertainties of the input variables and parameters from the bulk aerodynamic flux equation. Input variable time series were uniformly adjusted by a normally distributed random variable with a standard deviation given as follows: 1) the manufacturer's stated instrument accuracy of 0.3A degrees C for temperature (T), 0.3 m/s for wind speed (U (z)), 2% for relative humidity (RH), and 1 mb for pressure (P); 2) 0.0093 m for the aerodynamic roughness length (z (0)) based on z (0) profiles calculations from multiple heights; and 3) 0.08 m for measurement height (z). Often z is held constant; here we used a constant z compared to the ground surface, and subsequently altered z to account for the change in snow depth (d (s) ). The most important source of uncertainty was z (0), then RH. Accounting for measurement height as it changed due to snowpack accumulation/ablation was also relevant for deeper snow. Snow surface sublimation uncertainties, from this study, are in the range of 1% to 29% for individual input parameter perturbations. The mean cumulative uncertainty was 41% for the three water years with 55%, 37%, and 32% occurring for the wet, average, and low water years. The top three variables (z varying with d (s) , z (0), and RH) accounted for 74% to 84% of the cumulative sublimation uncertainty.
