    Abstract: This book contains the refereed contributions from the 43rd annual meeting of ISOTT. The annual meetings of ISOTT bring together scientists from various fields (medicine, physiology, mathematics, biology, chemistry, physics, engineering, etc.) in a unique international forum. ISOTT conferences are a place where an atmosphere of interaction is created, where many questions are asked after each presentation and lively discussions occur at a high scientific level. This vivid interaction is the main motivation for members to participate and gain new ideas and knowledge in the broad field of oxygen transport to tissue. The proceedings include sessions covered various research topics including Multi-Modal Imaging/Spectroscopy & Instrumentation; Cancer Metabolism; Cellular Hypoxia and Mitochondrial Function; Brain Oxygenation and Function; Other Organ Function and Metabolism; Oxygen Transport in Sports, Diseases and Clinical Care; Acupuncture, Meridians, and Primo Vascular System; EPR, MRS and MRI

    Notes: Summary Two numerical experiments were performed for sensitivity study of surface albedo, one was a control run in which the albedo values for snow-free surfaces were prescribed as constant; the other was a sensitivity run in which an albedo with seasonal variation was incorporated into the model show that the simulation of precipitation is sensitive to the surface albedo variations, especially those over Eastern Asia and the Sahara. Changes in surface albedo also have an impact on the monthly mean sea level pressure, especially on the July-mean Western Pacific subtropical high. Surface air temperature decreased over most of the Eastern Asia but increases over most of the Antarctica in July.

    Notes: Abstract For discrete-time systems, an H 2-suboptimal control problem is defined and analyzed. Then, an algorithm called H 2-suboptimal state feedback gain sequence (Algorithm A1) is developed. Rather than utilizing a perturbation method, which is numerically stiff and computationally prohibitive, Algorithm A1 utilizes a direct eigenvalue assignment method to come up with a sequence of H 2-suboptimal state feedback gains. Also, although the sequence of H 2-suboptimal state feedback gains constructed by Algorithm A1 depends on a parameter ɛ, the construction procedure itself does not require explicitly the value of the parameter ɛ. Next, attention is focused on constructing a sequence of H 2-suboptimal estimator-based measurement feedback controllers. Three different estimator structures (prediction, current, and reduced-order estimators) are considered. For a given H 2-suboptimal state feedback gain, a sequence of estimator gains for any of the three estimators considered can be constructed by merely dualizing Algorithm A1. The direct method of constructing H 2-suboptimal controllers developed here has a number of advantages over the perturbation method, e.g., it has the ability to design all three types of estimator-based controllers while still maintaining throughout the design the computational simplicity of it. This paper is the discrete-time version of Ref. 1. There are some conceptual similarities as well as fundamental differences between the H 2-suboptimal control problems for continuous-time and discrete-time systems. The fundamental differences arise mainly from the fact that, in contrast to continuous-time systems, for discrete-time systems the infimum of the H 2-norm over the class of strictly proper controllers is in general different from the infimum of the H 2-norm over the class of proper controllers.

    Notes: Abstract The gas exchange characteristics are reported for Amaranthus tricolor, a C4 vegetable amaranth of southeastern Asia. Maximum photosynthetic capacity was 48.3±1.0 μmol CO2 m-2 s-1 and the temperature optimum was 35°C. The calculated intercellular CO2 concentration at this leaf temperature and an incident photon flux (400–700 mm) of 2 mmol m-2 s-1 averaged 208±14 μl l-1, abnormally high for a C4 species. The photosynthetic rate, intercellular CO2 concentration, and leaf conductance all decreased with an increase in water vapor pressure deficit. However, the decrease in leaf conductance which resulted in a decrease in intercellular CO2 concentration accounted for only one fourth of the observed decrease in photosynthetic rate as water vapor pressure deficit was increased. Subsequent measurements indicated that the dependence of net photosynthesis on intercellular CO2 concentration changed with water vapor pressure deficit.

    Notes: Abstract The electrooxidation of glassy carbon electrodes in acid and neutral solution has been investigated using in situ FTIR spectroelectrochemical techniques. The formation and transformation of intermediate oxide species in different potential regions has been observed. The results show that in the lower anodic potential region (i.e., 〈 +1.2 V vs SCE), the main reaction is the transformation of oxide species (i.e. phenol-like species) initially on the carbon electrode surface. But in the high anodic potential region (i.e., 〉 + 1.65 V vs SCE), the electrooxidation of carbon is a combination of electrochemical and chemical oxidation. A more detailed electrooxidation mechanism is proposed based on the experimental results.

    Description / Table of Contents: Zusammenfassung Ein Fall einer rechtsmedizinischen Obduktion an der Leiche eines männlichen Kindes mit Hydranencephalie wird beschrieben, in welchem zunächst der Verdacht einer Kindstötung bestand. Das Kind war 48cm lang und 2,86kg schwer, die Umfänge des Kopfes, des Brustkorbs und des Abdomens waren 32,2cm, 31,0 cm, und 30,4cm. Kopf mit Körper waren normal geformt. Die Obduktion deckte jedoch einen schweren Defekt des Zentralnervensystems auf. Die Schädelhöhle war mit einer trüben, dunkelroten Flüssigkeit (ca. 310 ml) ausgefüllt. Die Gewebsreste des Zentralnervensystems waren überwiegend subtentoriale Strukturen des Hirnstamms, speziell Corpus mamillare, Corpora quadrigemina, Corpus pineale, Crura cerebri, Pons, Cerebellum, Medulla oblongata und Rückenmark. Die Basalganglien, Thalamus, Hypothalamus und das Chiasma opticum konnten nicht gefunden werden, obwohl eine atrophische Hypophyse sowie Augenbulbi und Sehnerven in den Augenhöhlen vorhanden waren. Die normale Verzweigung der cerebralen Blutgefäße, speziell der Äste der vorderen und mittleren Cerebralarterien und des Circulus arteriosus Willisi, fehlten trotz Vorhandensein der Arteriae carotides internae et externae. Andere Organe waren im allgemeinen gestaut. Die ausgeprägte Rindenatrophie der Nebennieren (links 0,5g, rechts 0,6g), spezielle der Zona fasciculata, war charakteristisch. Die Lungenschwimmprobe gab teilweise positive Resultate, dies war jedoch die Folge einer künstlichen Beatmung durch einen Mann des Rettungsdienstes zu erklären, weil Fruchtwasserbestandteile mikroskopisch festgestellt und vollständig entfaltete Alveolen nicht gefunden wurden. Im Resultat wurde eine Totgeburt des Kindes diagnostiziert. Todesursache war die Aspiration von Amnionflüssigkeit, verursacht durch einen schweren Defekt der vegetativen hypothalamischen Funktion infolge Hydranencephalie.
    Notes: Summary A medico-legal autopsy case of hydranencephaly in a male infant which was first suspected of maternal infanticide is reported. The infant was 48cm in height, weighed 2.86kg and the circumference of the head, the chest and the abdomen was 32.2cm, 31.0cm and 30.4cm, respectively, with no deformities of the head or body. Autopsy examination, however, revealed a severe defect in the central nervous system. The cranial cavity was filled with a cloudy dark red fluid (ca. 310ml) instead of the cerebral hemispheres. The residual central nervous tissues were mostly subtentorial structures from the midbrain to the spinal cord namely, corpus mamillare, corpora quadrigemina, corpus pineale, crus cerebri, pons, cerebellum, medulla oblongata and spinal cord. The basal ganglia, thalamus, hypothalamus and chiasma opticum could not be found, although atrophic hypophysis, eyeballs and optic nerves were present. The usual distribution of cerebral blood vessels, especially the branches of the anterior and middle cerebral arteries and Willis' ring, was absent despite the presence of the internal and external carotid arteries. Other organs were, in general, congestive. The marked cortical atrophy of the adrenal glands (left 0.5g, right 0.6g), especially the zona fasciculata, was characteristic. The hydrostatic lung test gave partially positive results, but this was considered to be due to artificial respiration by an ambulance man because amniotic fluid components were microscopically noted and fully expanded alveoli were not found. In conclusion, the cause of the infant's death was diagnosed as stillbirth due to aspiration of amniotic fluid caused by the severe defect of vegetative hypothalamic function through hydranencephaly.
