    Notes: In this paper, we introduce the notion of interval structures in an attempt to establish a unified framework for representing uncertain information. Two views are suggested for the interpretation of an interval structure. A typical example using the compatibility view is the rough set model in which the lower and upper approximations form an interval structure. Incidence calculus adopts the allocation view in which an interval structure is defined by the tightest lower and upper incidence bounds. The relationship between interval structures and interval-based numeric belief and plausibility functions is also examined. As an application of the proposed model, an algorithm is developed for computing the tightest incidence bounds.

    Notes: We apply rough set constructs to inductive learning from a database. A design guideline is suggested, which provides users the option to choose appropriate attributes, for the construction of data classification rules. Error probabilities for the resultant rule are derived. A classification rule can be further generalized using concept hierarchies. The condition for preventing overgeneralization is derived. Moreover, given a constraint, an algorithm for generating a rule with minimal error probability is proposed.

    Notes: A vein-yellowing disease of Ageratum conyzoides in Singapore was shown to be caused by a geminivirus, here named ageratum yellow vein virus (AYVV), which was transmitted by the whitefly Bemisia tabaci but not by inoculation with sap or through seed. AYVV particles (30 × 20 nm) are serologically related to those of other whitefly-transmitted geminiviruses, and reacted with some monoclonal antibodies elicited by particles of African cassava mosaic or Indian cassava mosaic geminiviruses. However, the epitope profile of AYVV differed from the profiles of these viruses, and from those of geminiviruses from vein yellowing-affected A. conyzoides from India and from yellow leaf curl-affected tomato from either Singapore or India. The results provide further evidence of antigenic differences among geminiviruses that cause similar diseases in the same plant species in different geographical regions.

    Notes: regina freestone peaches from california were given low postharvest doses of gamma radiation (65-75 krads) and were compared with non-irradiated controls approximately one month after harvest. Practiced judges were used, with a technique of minimal cross-sensory interference, as an analytical tool to guide subsequent instrumental analysis. Strong differences were found in odor and components of taste not associated with sweetness. Lesser trends were noted for firmness and appearance. Untrained subjects also detected gross sensory differences.

    Notes: Bing cherries from California were given low postharvest doses of gamma radiation (60-80 Krads) and were compared with nonirradiated controls during a period 3-11 days after harvest. Irradiated cherries showed a greater degree of shrivelling, a trend to be softer on chewing and also exhibited flavor differences. Trends for consistent differences in firmness tested manually, darkness of skin color and degree of brown blemishing were not noted.

    Notes: Navel oranges from two locations in California were given low postharvest doses of gamma radiation (60 - 80 Krads) and compared with nonirradiated controls for taste, flavor, odor, firmness, degree of orange color, degree of brown blemishing, ease of peeling and intactness of the membranes on sectioning. Practiced judges were used as an analytical screening tool using minimal cross-sensory interference, while untrained subjects were used to determine whether changes might be distinguished by‘nonexperts’. Greatest differences were found for degree of blemishing, lesser differences for flavor by mouth and odor and some trends for taste, color, texture and ease of peeling.

    Notes: Summary Extensive artificial hybridisation among members of some 86 genera of vandaceous orchids within the subtribe Sarcanthinae in Singapore over the past five decades has created many thousands of exotic hybrids. A small number of these are selected for commercial cut-flower production, while others are cultivated as pot-plants. Two classes of intergeneric hybrids are of special commercial importance as export cut-flowers, the bigeneric Aranda (Arachnis x Vanda) and the trigeneric Mokara (Arachnis x Vanda x Ascocentrum) hybrids. Cytogenetic studies of these hybrids in recent years have provided information on the significance of ploidy levels and genomic constitutions on the horticultural performance of cut-flower cultivars, and also on the strategy for effective breeding in vandaceous orchids.

    Notes: Abstract Incidence calculus is a mechanism for uncertain reasoning originally introduced by Bundy. He suggested a set of inference rules for deriving new incidence bounds from a given set of lower and upper bounds of some propositions. However, it is important to demonstrate that the inference axioms are complete in any axiomatization. It is proved in this paper that inference rules used by Bundy are indeed complete.
