We investigate whether controlling shareholders expropriate corporate resources during a financial crisis using the data of Thai firms. Our results are consistent with the argument of Friedman, Johnson, and Mitton (2003) that the propensity to tunnel and prop is higher for business groups in particular if they are organized in pyramids. Specifically, we find that firms that belong to the top 30...

Mummichogs (Fundulus heteroclitus; Cyprinodontiformes) are intertidal killifish that can breathe air and locomote on land. Our goals were to characterize the terrestrial locomotion of mummichogs and determine their method of navigation towards water in a terrestrial environment. We used high-speed video to record behavior during stranding experiments and found that mummichogs use a tail-flip ju...

This paper proposes a new version of a method (G-Prop-III, genetic backpropaga-tion) that attempts to solve the problem of nding appropriate initial weights and learning parameters for a single hidden layer Mul-tilayer Perceptron (MLP) by combining a genetic algorithm (GA) and backpropagation (BP). The GA selects the initial weights and the learning rate of the network, and changes the number o...

Systemic exposure of the antidepressant S-citalopram (escitalopram, SCIT) differs several-fold according to variable cytochrome P450 2C19 activity, demonstrating the importance of this enzyme for the metabolic clearance of SCIT in vivo. However, previous studies have indicated that the involvement of CYP2C19 in formation of the metabolite N-desmethyl S-citalopram (SDCIT) is limited. Therefore, ...

In this paper, we propose an inference procedure for deep convolutional neural networks (CNNs) where partial evidence might be available during inference. We introduce a general feedback-based propagation approach (feedbackprop) that allows us to boost the prediction accuracy of an existing CNN model for an arbitrary set of unknown image labels when a non-overlapping arbitrary set of labels is ...

Abstract. Biotransformations are chemical reactions carried out by microorganisms on organic substrates. can be regio-, chemo-, stereo- and enantio-selective. Bioreductions of great interest to the food pharmaceutical industries as they help reduce costs impacts environment. In this work, following biotransformations chalcones were performed: (2E)-1-(4-hydroxy-phenyl)-3-(2-methoxy-phenyl)-prop-...

Extrapolation of results from empirical studies of natural or anthropogenic perturbations are a useful tool in estimating potential effects of future impacts, For 5 years we studied the direct effects of a major oil spill on fringing red mangroves (Rhizophora mangle) and the organisms that live attached to their submerged prop roots, Based on these data, we here estimate the effects of this oil...

The unstable isomeric compounds 5-hydroxy-7-prop-2-en-(E)-ylidene-7,7adihydro-2H-cyclopenta[b]pyran-6-one (1) and 5-hydroxy-7-prop-2-en-(Z)-ylidene-7,7adihydro-2H-cyclopenta[b]pyran-6-one (2), previously described as antimicrobial metabolites from the sponge Ulosa sp., were isolated and identified as major components of the ascidian Diplosoma virens. In this paper, full spectral data for 2 and ...

The California Stem Cell Research and Cures Act, also called Proposition 71 [5], was a ballot initiative proposed by California voters in 2004 to allocate three billion dollars of state funds for stem cell research over ten years. Endorsed by California scientists and patient-advocates, Prop 71 passed on 2 November 2004, amending the state constitution to make stem cell research a constitutiona...
