    Notes: Abstract Rapid advances in multimedia technology necessitate the development of a generic multimedia information system with a powerful retrieval engine for prototyping multimedia applications. We develop a content-based retrieval engine (CORE) that makes use of novel indexing techniques for multimedia object retrieval. We formalize the concepts related to multimedia information systems such as multimedia objects and content-based retrieval. We bring out the requirements and challenges of a multimedia information system. The architecture of CORE is described in detail along with the associated retrieval mechanisms and indexing techniques. Various modules developed for efficient retrieval are presented with some APIs. The efficacy of CORE is demonstrated in the development of two multimedia systems, a computer-aided facial image inference and retrieval (CAFIIR) system and a system for trademark archival and retrieval (STAR), which have been developed at the Institute of Systems Science (ISS). We expect that CORE will be useful for effective prototyping of other such multimedia applications.

    Notes: Abstract We report in this study a patient who developed repeated convulsions as a result of valproate therapy. MELAS (mitochondrial myopathy, encephalopathy, lactic acidosis and stroke-like episodes) was subsequently diagnosed and a nucleotide 3243 A→G mutation was detected in the mitochondrial DNA. This mutation predisposes the patient to the detrimental effects of valproate on oxidative phosphorylation. Conclusion We support the suggestion of Ponchaut et al. [14] that valproate should not be given to patients suspected of having mitochondrial diseases. In addition, for patients whose seizures worsen with valproate therapy, an inborn error of mitochondrial metabolism should be suspected. The underlying mitochondrial DNA defects should be sought for family screening and genetic counselling.

    Notes: Abstract Goitre is common among growing children and adolescents. To define the aetiology of goitre in adolescents of Hong Kong and to examine their current level of iodine intake, this cross-sectional survey of goitre in high school students was performed and urine samples were collected for the analysis of iodine excretion. Screening examinations were carried out in 2439 secondary school students aged 12–18 years from ten randomly selected high schools in Hong Kong. Blood samples were obtained from all goitrous subjects for the determination of serum TSH, free T4 and thyroid antibodies. We obtained 476 random urine samples and 80 24-h urinary collections for the analysis of iodine excretion. Of these, 85 subjects (3.5%) had goitre, 70 had simple goitre. Chronic lymphocytic thyroiditis was found in ten subjects. Two had Graves' disease and three had nodular goitre. The median urinary iodine concentration for the random urine samples was 190 μg/l (1.50 μmol/l) or 158 μg/g creatinine. The median 24-h urinary excretion of iodine was 189 μg (1.49 μmol) per day. Conclusion This cross-sectional study demonstrates the spectrum of thyroid disease in Chinese adolescents in Hong Kong. Their urinary iodine excretion was adequate and much higher than those of children from many European countries and coastal cities of China.

    Description / Table of Contents: Riassunto In questo lavoro si applica la teoria della matriceU per dedurre un'espressione esplicita per lo spettro d'energia di eccitazione dell'4He liquido. Usando un modello per il potenziale chimico efficace per l'4He si è in grado di produrre uno spettro di eccitazione molto simile a quello osservato. L'inverso della massa efficace, cioè 1/m *, è ottenuto in funzione del momentok. Si trova che il rapporto tra massa efficace e la massa dell'atomo di elio ak=2.0 Å−1, cioè vicino alla profondità del rotore, èm * (k=2.0 Å−1)/m He= =0.18298, mentre quello ak=1.0 Å−1 èm * (k=1.0 Å−1)/m he=−0.17103. Il risultato teorico dello spettro di eccitazione è coerente con i dati sperimentali.
    Abstract: Резюме В этой статье мы применяем теориюU-матрицы для вывода явного выражения для энергетического спектра возбуждений Зидкого4He. Используя модель для эффективного химического потенциала для4He, мы воспроизводим спектр возбуждений который оказывается очень близким к зкспериментально наблюдаемому. Вычисляется обратная величина эффективной массы, т.е. 1/m *, как функция импульсаk. Получено отношение эффективной массы к массе атома гелия приk=2.0 Å−1, которое составляетm * (k=2.0 Å−1)/m He=0.18298, тогда как это отношение приk=1.0 Å−1 равноm * (k=1.0 Å−1)/m He=−0.17103. Теоретический результат для спектра возбужений согласуется с имеющимися экспериментальными данными.
    Notes: Summary In this paper, we apply theU-matrix theory to derive an explicit expression for the excitation energy spectrum of liquid4He. Using a model for the effective chemical potential for4He, we are able to produce an excitation spectrum which is very close to the observed one. The inverse of the effective mass,i.e. 1/m *, is obtained as a function of momentumk. The ratio between the effective mass and the mass of helium atom atk=2.0 Å−1,i.e. near the roton depth, is found to bem *(k=2.0 Å−1)/m He=0.18298, while the ratio atk=1.0 Å−1 ism *(k=1.0 Å−1)/m He=−0.17103. The theoretical result of the excitation spectrum is consistent with observational data.
