  • Multimedia Montage—Counterpoint Synthesis of Movies
    Multimedia Tools and Applications, 2000
    Co-Authors: R. Suzuki, Y. Iwadate, Ryohei Nakatsu, Michihiko Mihoh
    Abstract:

    In this paper, we propose “Multimedia Montage”, which is the structural synthesis in time and space of multimedia components, such as movies and sounds, as a new image expression method for communications. In this study, we introduce the counterpoint theory in music to compose movie structures, and we use scripts to describe the structures. The nature of counterpoints lies in the parallelism of autonomous elements and they fit today's multimedia technologies very well. We confirm the effectiveness of our method by making example movies based on the counterpoint theory, developing a prototype system, and conducting movie synthesis experiments using the prototype. Our next goal is to achieve automatic synchronization among multimedia components based on their Internal Rhythms, which we have observed in experiments.

  • central carbon metabolism and electron transport in chlamydomonas reinhardtii metabolic constraints for carbon partitioning between oil and starch
    Eukaryotic Cell, 2013
    Co-Authors: Xenie Johnson, Jean Alric
    Abstract:

    ABSTRACT The metabolism of microalgae is so flexible that it is not an easy task to give a comprehensive description of the interplay between the various metabolic pathways. There are, however, constraints that govern central carbon metabolism in Chlamydomonas reinhardtii that are revealed by the compartmentalization and regulation of the pathways and their relation to key cellular processes such as cell motility, division, carbon uptake and partitioning, external and Internal Rhythms, and nutrient stress. Both photosynthetic and mitochondrial electron transfer provide energy for metabolic processes and how energy transfer impacts metabolism and vice versa is a means of exploring the regulation and function of these pathways. A key example is the specific chloroplast localization of glycolysis/gluconeogenesis and how it impacts the redox poise and ATP budget of the plastid in the dark. To compare starch and lipids as carbon reserves, their value can be calculated in terms of NAD(P)H and ATP. As microalgae are now considered a potential renewable feedstock, we examine current work on the subject and also explore the possibility of rerouting metabolism toward lipid production.

  • Melatonin Relations with Energy Metabolism as Possibly Involved in Fatal Mountain Road Traffic Accidents
    International journal of molecular sciences, 2020
    Co-Authors: Claus Behn, Nicole De Gregorio
    Abstract:

    Previous results evidenced acute exposure to high altitude (HA) weakening the relation between daily melatonin cycle and the respiratory quotient. This review deals with the threat extreme environments pose on body time order, particularly concerning energy metabolism. Working at HA, at poles, or in space challenge our ancestral inborn body timing system. This conflict may also mark many aspects of our current lifestyle, involving shift work, rapid time zone crossing, and even prolonged office work in closed buildings. Misalignments between external and Internal Rhythms, in the short term, traduce into risk of mental and physical performance shortfalls, mood changes, quarrels, drug and alcohol abuse, failure to accomplish with the mission and, finally, high rates of fatal accidents. Relations of melatonin with energy metabolism being altered under a condition of hypoxia focused our attention on interactions of the indoleamine with redox state, as well as, with autonomic regulations. Individual tolerance/susceptibility to such interactions may hint at adequately dealing with body timing disorders under extreme conditions.

  • Life after harvest: circadian regulation in photosynthetic pigments of rocket leaves during supermarket storage affects the nutritional quality
    MDPI, 2019
    Co-Authors: Ruiz De Larrinaga, Lorena, Resco De Dios, Víctor, Fabrikov Dmitri, Guil Guerrero, José Luis, Becerril, José María, García-plazaola, José Ignacio, Esteban Raquel
    Abstract:

    Vegetables, once harvested and stored on supermarket shelves, continue to perform biochemical adjustments due to their modular nature and their ability to retain physiological autonomy. They can live after being harvested. In particular, the content of some essential nutraceuticals, such as carotenoids, can be altered in response to environmental or Internal stimuli. Therefore, in the present study, we wondered whether endogenous Rhythms continue to operate in commercial vegetables and if so, whether vegetable nutritional quality could be altered by such cycles. Our experimental model consisted of rocket leaves entrained under light/darkness cycles of 12/12 h over 3 days, and then we examined free-run oscillations for 2 days under continuous light or continuous darkness, which led to chlorophyll and carotenoid oscillations in both constant conditions. Given the importance of preserving food quality, the existence of such Internal Rhythms during continuous conditions may open new research perspective in nutrition science. However, while chromatographic techniques employed to determine pigment composition are accurate, they are also time-consuming and expensive. Here we propose for the first time an alternative method to estimate pigment content and the nutritional quality by the use of non-destructive and in situ optical techniques. These results are promising for nutritional quality assessments
