It is proved that there is a one to one correspondence between representations of C^*-ternary ring M and C^*-algebra 𝒜(M). We discuss primitive and modular ideals of a C^*-ternary ring and prove that a closed ideal I is primitive or modular if and only if so is the ideal 𝒜(I) of 𝒜(M). We also show that a closed ideal in M is primitive if and only if it is the kernel of some irreducible representation of M. Lastly, we obtain approximate identity characterization of strongly quasi-central C^*-ternary ring and the ideal structure of the TRO V ⊗^tmin B for a C^*-algebra B.

Primitive chain network model for block copolymers is used here to simulate molecular dynamics in the entangled state with acceptable computational cost. It was found that i) the hooking procedure rearranging the topology of the entangled network is critical for the equilibrium structure of the system, and ii) simulations accounting for the different chemistry, i.e., with a biased hooking probability based on interaction parameter ${\chi}$ for selection of the hooked partner, generates a reasonable phase diagram.

We analysed a hardware design issues, which is strong, compact and efficient. Due to its low area constraints, primitive based on hardware is especially suited for RFID (Radio Frequency Identification) devices. primitive is based on the classical DES (Data Encryption Standard) design. This approach makes it possible to considerably decrease chip size requirements.

An oceanographic measurement by Senjyu and Watanabe (1999) shows that a sudden drop of temperature in the northern Japanese coastal regions occurs with the passing of Typhoon Oliwa, September in 1997. The temperature variation ranges 6 to 7$^{\circ}C$. A three-dimensional primitive model (Princeton Ocean Model) is implemented to examine how it happens. (omitted)

Non-verbal information plays an important role not only in human-to-human communications but also in human computer interaction. In this paper, we examine effects of human-like agent's primitive movements on user's impression, where the human-like agent's primitive movements include eye, mouth, and head. SD (Semantic Differential) method was used for evaluation, and two factors were extracted as a result of the factor analysis. It is found that the first factor influenced the user's impression particularly.

Let g be a continuous function on an interval I which is not constant on any subinterval of I, and let ${\mu}$ be a Borel measure on I. In this paper we give a necessary and sufficient conditions guaranteeing, for the strongly measurable function f on I with values in a Banach space X, the existence of a continuous primitive function F on I with respect to g.

Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its read. Most of the sources of security and privacy issues in RFID technology arise from the violation of the air interface between a tag and its reader. This paper will approach consideration of security analysis with cryptographic primitive based on hardware basis.

The prenatal development of lateral motor columns in the lumbar spinal cord was studied by electron microscopy in human embryos and fetuses ranging from 9 mm to 260 mm crown-rump length ($5{\sim}30$ weeks of gestational age). At 9 mm embryo, the lateral motor column were developed from ventro-lateral projection into the marginal layer and composed of primitive neuroblasts. At 20 mm embryo the primitive motor neurons were packed closely together and could readly be distinguished from primitive glioblasts by a presence of large nuclei. The primitive multipolar neurons were observed in lateral motor column at 40 mm fetus. At 80 mm fetus multipolar neurons were characterized by their many dendrites and axons in the vicinity of motor neuron perikarya. At 260 mm fetus, the motor neurons were large and contained all intracytoplasmic structures in the cytoplasm which were also found in mature motor neuron in lateral motor column. The first axo-dendritic synapses found at 40 mm fetus and increased in number throughout fetal development. Axo-somatic synapses with spherical vesicles were first observed at 80 mm fetus. A few axo-somatic synapses were found at next prenatal stages. Axo-dendritic and axo-somatic synapses contained mixed populations of spherical and flattened vesicles by 120 mm fetus. These findings indicate that axo-dendritic synapses develop prior to axo-somatic synapses in the spinal cord during neurogenesis.
