    Notes: The dynamics of domain walls in an ac magnetic field is formulated and solved numerically under free boundary conditions. Previous calculations are applicable only in the limit when the sample size is much less than the bare penetration depth, whereas no such approximation is made in the present approach. Our calculation provides for an interpretation of recent experimental results that observe a peak in the ac susceptibility of soft magnets as a function of the amplitude of the external magnetic field. © 2000 American Institute of Physics.

    Prey-size Preference, Maximum Handling Size, and Consumption Rates for Redear Sunfish Lepomis microlophus Feeding on Two Gastropods Common to Aquaculture Ponds (2003)

    Notes: Maximum handling sizes, prey size and species preferences, and ad libitum consumption rates were determined for three size classes of redear sunfish Lepomis microlophus feeding on Physa gyrina and Helisoma trivolvis, two common aquaculture-pond snails which serve as intermediate hosts for fish parasites. Maximum handling-size experiments indicated that redear sunfish as small as 14-cm total length were capable of consuming all sizes of Physa typically observed in ponds, whereas only redear sunfish of at least 32-cm total length are capable of consuming all commonly observed sizes of pond-dwelling Helisoma. When presented with a range of sizes of both snail species, redear sunfish consumed higher proportions of smaller- and medium-sized snails; the largest snails offered were uneaten or consumed in relatively small quantities. Multiple linear regression was applied to consumption data to develop a simple model for predicting mean daily ad libitum consumption rate (g/g per d) for redear sunfish feeding on snails with temperature (20–27 C) and fish total length (9–24 cm) as independent variables. Our findings will facilitate prediction of numbers of redear sunfish of a given size required to control populations of Physa and Helisoma in ponds. Such predictions will enable pond owners to quickly evaluate whether stocking redear sunfish as a control agent for undesirable snail populations will be economically and logistically feasible. Findings also indicate potential limitations in the use of redear sunfish to control populations of Helisoma due to the inability of redear sunfish as large as 24-cm total length to consume the largest 30–40% of Helisoma commonly observed in ponds and to the expense of stocking larger fish (32-cm total length) capable of consuming all sizes of Helisoma.

    Broodstock Rearing and Controlled Reproduction of Reeves Shad Tenualosa reevesii (2003)

    Notes: Reeves shad Tenualosa reevesii is one of China's best known anadromous fish, but is presently on the verge of extinction. There is an urgent need for conservation of this species through artificial reproduction and culture. In this study, shad broodstock were held in captivity then were induced to spawn with serial injections of luteinizing hormone-releasing hormone analogue (LHRHa) following GtH priming by implantations of 17-methytestosterone (T) combined with environmental manipulations. Induced maturation of 4, 5, and 6-year-old females reached 83.3%, 87.5%, and 100%, respectively, while fish in control treatments remained immature. During the gonadal development priming period, mean serum 17-estradiol levels in the T treatment were significantly higher than the LHRHa treatment and control fish. Gonadal development of females was suppressed when their mesenteric fat index was below 1.5% by April. The effective accumulating temperatures for female and male maturation were 3,995 ± 31.4 C/d and 2,278 ± 8.9 C/d, respectively. Two injections of LHRHa in combination with domperidone (DOM) and environmental regulations were effective in inducing ovulation. About 800,000 fertilized ova were obtained (fertilization 75%) in 1995, and 5,000 fry were hatched in 1996. These results are an important step to develop shad culture and save this endangered species.

    Minimization of MRF Energy with Relaxation Labeling (1997)

    Notes: Abstract Recently, there has been increasing interest in Markovrandom field (MRF) modeling for solving a variety of computer visionproblems formulated in terms of the maximum a posteriori(MAP) probability. When the label set is discrete, such as in imagesegmentation and matching, the minimization is combinatorial. Theobjective of this paper is twofold: Firstly, we propose to use thecontinuous relaxation labeling (RL) as an alternative approach forthe minimization. The motivation is that it provides a goodcompromise between the solution quality and the computational cost.We show how the original combinatorial optimization can be convertedinto a form suitable for continuous RL. Secondly, we compare variousminimization algorithms, namely, the RL algorithms proposed byRosenfeld et al., and by Hummel and Zucker, the mean field annealing ofPeterson and Soderberg, simulated annealing of Kirkpatrick, theiterative conditional modes (ICM) of Besag and an annealing versionof ICM proposed in this paper. The comparisons are in terms of theminimized energy value (i.e., the solution quality), the requirednumber of iterations (i.e., the computational cost), and also thedependence of each algorithm on heuristics.

    Robust Estimation of Rotation Angles from Image Sequences Using the Annealing M-Estimator (1998)

    Notes: Abstract A robust method is presented for computing rotation angles of image sequences from a set of corresponding points containing outliers. Assuming known rotation axis, a least-squares (LS) solution are derived to compute the rotation angle from a clean data set of point correspondences. Since clean data is not guaranteed, we introduce a robust solution, based on the M-estimator, to deal with outliers. Then we present an enhanced robust algorithm, called the annealing M-estimator (AM-estimator), for reliable robust estimation. The AM-estimator has several attractive advantages over the traditional M-estimator: By definition, the AM-estimator involves neither scale estimator nor free parameters and hence avoids instabilities therein. Algorithmically, it uses a deterministic annealing technique to approximate the global solution regardless of the initialization. Experimental results are presented to compare the performance of the LS, M- and AM-estimators for the angle estimation. Experiments show that in the presence of outliers, the M-estimator outperforms the LS estimator and the AM-estimator outperforms the M-estimator.

    Notes: Abstract  The interaction between anionic surfactants and polyvinylpyrrolidone (PVP) are investigated using 13C NMR, ESR spectroscopy and surface tension measurements at the air/water interface. The behavior of single-chained surfactant, sodium dodecyl sulphonate (AS), is compared with that of the double-chained surfactant, sodium bis(2-ethylhexyl) phosphate (NaDEHP). The results showed that a surfactant–polymer complex of “necklace and head structure” is formed in AS aqueous solutions in the presence of PVP due to the hydrophobic interaction between PVP and AS. The AS micelles nucleate on the polymer hydrophobic sites, and the mobility of the AS head groups is not affected. But, for NaDEHP surfactant, it was found that PVP is little effective in influencing the monomer–micelle equilibrium and no surfactant– polymer complex formed in the NaDEHP aqueous solution.
