Greyscale morphology is more efficient and useful for processing greyscale image. It is the extension of binary morphology by use of a min or max operations. Optics is suitable for the implementation of morphological transformations because of its parallelism. However, greyscale morphology with both greyscale images and greyscale structuring elements is difficult to realize threshold decomposition since it does not commute with threshold. We propose a correlation approach for greyscale morphological transformations using area-coding technique to represent the umbra of surfaces of both greyscale image and greyscale structuring element. A primary experiment of greyscale dilation is presented.

The genome-enzyme complex is isolated from the silkworm cytoplasmic polyhedrosis viruswith DEAE-Sephadex column chromatography after ultraviolet irradiation. The genome-enzyme complex shows both RNA-polymerase and methyltransferase activities while using ~3H-UTP and [~3H-methyl]-S-adenosyle-L-methionine as substrates. Like the double-stranded RNAgenome of CPV, the genome-enzyme complex eould be separated into nine segments on pol-yacrylamide gel electrophoresis. It is demonstrated that the RNA po1ymerase and methyl-transferase are tightly bound to the double-stranded RNA genome and that the individualsegments of the genome-enzyme complex all possess RNA-polymerase and methyltransferaseactivities. It appears that each segment of the double-stranded RNA genome is transcribedindependently.

According to the electron microscopic observation the wheat yellow curl-leaf disease wascaused by a rickettsia-like organism (RLO). The morphology and structure of the pathogenand its distribution within the host plant were of typical characteristics of the RLO. RLO_Swere seen in the phloem and xylem of the host plant. In xylem elements RLO particleswere closely related to electron-dense materials spreading in them. Some channels wereformed in the cell walls of protoxylem, and sometimes in the cell walls of mature xylem ele-ments which were eroded. RLOs entered adjacent cells and intercellular spaces via thesechannels. A large number of RLOs were seen in sieve elements and they could get intoadjacent sieve elements via sieve pores. The places of intercellular movement of RLOs weremostly in the plasmodesmata-dense areas or pit fields where the primary cell walls amongplasmodesmata were dissolved to form some channels by the invasion of RLOs. And theforming of less intercellular channels did not relate to plasmodesmata and pit fields. Basedon these results the mechanism of systematical infection of host plant caused by the RLO isdiscussed in this paper.

In this paper, we report the synthesis of the 5’-half molecule of yeast alanine tRNA (tRNAyAla) by ligating three oligonucleotide fragments corresponding to the nucleotide sequences 1-13, 14-22 and 23-35 respectively under the catalysis of T4 RNA ligase （Fig. 1）. Because of the high purity of the oligonuclcotide fragments and the excellent quality of T4RNA ligase and polynucleotide kinase we prepared, the isolation steps were simplified and the overall yields were much higher. The ligating yield of the docosamer （Ⅳ） was 75%, that of the pentatriacontamer （Ⅴ）, 90%, and the isolated yield of the final product was 21% calculated on the basis of the tridecamer （Ⅲ） used in the. first reaction. Under the action of T4 RNA ligase the synthetic 5’-half molecule was joined with the natural 3’-half molecule forming a semi-synthetic tRNAyAla, which possessed the biological activities of both accepting （3H）-alanine and incorpprating it into proteins. The correctness of the structure of the synthetic 5

Stack filters are more general and robust nonlinear filters than median filter, which possess threshold decomposition and stacking properties. Stack filters can be carried out one step using optical parallel fuzzy logic technique instead of three steps in threshold decomposition. All window, width 3 stack filters but two trivial stack filters are expressed in unified expression with coefficiencies to choose desired stack filter, so they are realized by an optical approach, window 3×3 separable stack filters can be realized by cascading the window width 3 stack filters. Window width 5 stack filters can be realized using the same method.
