    Low temperature spin dynamics of geometrically frustrated antiferromagnets Y2Mo2O7 and Y2Mo1.6Ti0.4O7 studied by muon spin relaxation : The 40th annual conference on magnetism and magnetic materials (1996)

    Notes: The spin dynamics of geometrically frustrated pyrochlore antiferromagnets Y2Mo2O7 and Y2Mo1.6Ti0.4O7 have been investigated using muon spin relaxation. In Y2Mo2O7 a dramatic slowing down of the Mo4+ spin fluctuations occurs as one approaches the spin freezing temperature TF of 22 K from above. At lower temperatures the spins freeze into a disordered magnetic state similar to that found in a spin glass but with a small residual muon spin relaxation rate at low temperatures. This residual relaxation rate is larger in Y2Mo1.6Ti0.4O7 where TF=15 K. These results suggest that there is a nonzero density of states for magnetic excitations in these systems near zero energy. © 1996 American Institute of Physics.

    Notes: Rhizopus stolonifer causes severe losses to Israeli grape exports. The fungus develops on mature berries in the field, during storage at temperatures above 08C and during shelf-life. It was isolated from naturally contaminated soils throughout the year, and from fruits after mid-June. The airborne spore population increased in vineyards at the time of fruit maturation and was related to the proximity of stone-fruit orchards. The size of this population was highly correlated with disease incidence and thus may be a satisfactory tool for disease prediction. Intact young berries were more resistant than mature ones to Rhizopus inoculation, in both the vineyard and in the laboratory. Mechanical wounding, or chloroform dips, dramatically increased the susceptibility of young berries. The decline in acidity and the increase in the soluble solids content during growth and maturation of the berry were accompanied by an increase in susceptibility to inoculation. Scanning electron microscopy showed the fruit surface to be covered with white amorphous structures. At higher magnifications small cracks (approximately 1 μm in length) were observed on the surface but in no case was fungal penetration noticed through these cracks. In artificially inoculated fruits the fungus germinated near the wound and developed vigorously inside and around the fissure, producing sporangia. The young sporangium is covered by a smooth external layer which is compressed against the sporangiospores. After lysis of the cover, the young hexagonal sporangiospores can be observed. With maturation, the columella collapses and the mature sporangiospores are dispersed. In naturally infected berries, an important path for fungal penetration is the incomplete connection between the berry and the pedicle. Heavily infested berries become disconnected from their pedicles. Two chemicals applied to the surrounding atmosphere, orthophenyl phenate (as a fog) and calcium hypochlorite (as chlorine vapour), significantly decreased postharvest decay in artificially inoculated berries.

As this is the lower bound of the symmetry detection problem for the considered output form, our algorithm is optimal. We show that a slight modification of our symmetry detection algorithm can be used to solve the related conguity problem of polyhedra.

    Notes: Abstract We propose a simple and efficient general algorithm for determining both rotational and involutional symmetries of polyhedra. It requiresO(m 2) time and usesO(m) space, wherem is the number of edges of the polyhedron. As this is the lower bound of the symmetry detection problem for the considered output form, our algorithm is optimal. We show that a slight modification of our symmetry detection algorithm can be used to solve the related conguity problem of polyhedra.

    Restoring subsampled color images (1999)

    Keywords: Key words:Demosaicing – Color interpolation – Regularization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Computer Science
    Notes: Abstract. In some capturing devices, such as digital cameras, there is only one color sensor at each pixel. Usually, 50% of the pixels have only a green sensor, 25% only a red sensor, and 25% only a blue sensor. The problem is then to restore the two missing colors at each pixel – this is called “demosaicing”, because the original samples are usually arranged in a mosaic pattern. In this short paper, a few demosaicing algorithms are developed and compared. They all incorporate a notion of “smoothness in chroma space”, by imposing conditions not only on the behavior of each color channel separately, but also on the correlation between the three channels.

    The effect of change in skin temperature due to evaporative cooling on sweating response during exercise (1997)
    Springer
    International journal of biometeorology 40 (1997), S. 99-102

    ISSN: 1432-1254

    Notes: Abstract  The purpose of this study was to investigate whether there are any effects of skin temperature changes on sweating response in the first few minutes of mild exercise. Six healthy males performed a bicycle exercise at 100 W (50 rpm) for 30 min under an ambient temperature of 23° C (40% RH). Esophageal temperature (T es), mean skin temperature (T– sk), local skin temperature at the lower left scapula (T sl), local sweating rate (M. sw), and cutaneous blood flow by laser-Doppler flowmetry (LDF) were measured continuously. Although T sl decreased markedly just after the onset of sweating, T– sk did not change. M. sw did not increase constantly in the early stages of exercise, and there was a temporary interruption in the increase of M. sw. This interruption in sweating was affected by the rate of change in T sl rather than by the absolute value of T sl, since there was a positive and significant correlation between the time of the interruption in the increase of M. sw and the rate of decrease in T sl (y=6.47x+0.04; r=0.86, P〈0.05). The results suggest that sweating response in the early stages of exercise may be influenced by changes in local skin temperature due to evaporative cooling.

    Postharvest disinfestation of diapausing and non-diapausing twospotted spider mite (Tetranychus urticae) on persimmons: hot water immersion and coolstorage (1997)

    Notes: Abstract The mortality response of diapausing and non-diapausing twospotted spider mite (Tetranychus urticae Koch) on persimmons to hot water immersion treatments between 44 and 54 °C was examined, for potential as a quarantine treatment. The mean immersion time for mean 99% mortality (LT99) of diapausing mites at 44 °C was 211 min, and this time decreased with increasing temperature to 3.6 min at 54 °C. Non-diapausing mites were found to be less tolerant to temperatures below 48 °C, with an estimated LT99 of 102 min at 44 °C, but had similar thermotolerance above 48 °C. In 47 °C water the immersion time required to kill 99% of diapausing mites was estimated at 67 min. This time was not reduced by subsequent coolstorage at 0 °C for up to eight weeks. Rather, coolstorage had the effect of keeping mites alive, relative to LT99 estimates calculated for mites stored at 20 °C. Similarly the thermotolerance of mites did not change with increased time in diapause, even though mites in diapause for 12 weeks had high control mortality. Hot water immersion appears to be a potentially useful disinfestation method for persimmons.

    Tissue-Specific Expressed Sequence Tags from the Black Tiger Shrimp Penaeus monodon (1999)

    Notes: Abstract: Expressed sequence tag data were generated from complementary DNA libraries created from cephalothorax, eyestalk, and pleopod tissue of the black tiger shrimp (Penaeus monodon). Significant database matches were found for 48 of 83 nuclear genes sequenced from the cephalothorax library, 22 of 55 nuclear genes from the eyestalk library, and 6 of 13 nuclear genes from the pleopod library. The putative identities of these genes reflected the expected tissue specificity. For example, genes for digestive enzymes were identified from the cephalothorax library and genes involved in the visual and neuroendocrine system from the eyestalk library. A few sequences matched anonymous EST or genomic sequences, and others contained mini-satellite or microsatellite repeat sequences. The remainder, 31 from the cephalothorax library, 25 from the eyestalk library, and 5 from the pleopod library, were sequences of high nucleotide complexity with no matches in any database searched and thus may represent novel genes.
