我々は遺伝子塩基配列中のエクソン・イントロン境界を判別する有効な手法の一つとして遺伝的プログラミング(Genetic Programming : GP)について研究を行ってきた. これまで, A, G, C, Tで表される4種の塩基記号を2または4ビット長で符号化しモデル生成を行っていたが, 各ビットを独立して入力とするため生成されたモデルは塩基記号を直接反映していなかった. 2または4ビットで符号化すると入力する候補が2倍, 4倍になるので学習モデルの生成までに多くの入力候補の組み合わせを試さなくてはならない. そこで本報告では塩基記号を直接入力とするモデルをGPにより生成する手法と生成した境界判別モデルの判別率について報告する.

Waveform distortion is a serious problem in higher-frequency signals on printed circuit boards (PCB). In order to overcome this problem, the segmental transmission line (STL) has already been proposed. However, the STL requires segments of wide-range widths. The wide-range line-width impedes higher optimization of waveforms and it also causes cost-increment in the PCB manufacturing. In this paper, we propose a novel STL with variable length segments in order to overcome the difficulties in previous work. We also develop a design methodology using a GA to determine the parameters for the proposed STL. We apply our new STL to the clock line in the actual PCB, and show its effectiveness compared with the previously proposed STL. © 2005 IEEE.

Abstract ###Finding transcription regulatory elements (TREs) is one of the most important tasks in the ###field of genome informatics. The objective of this research is to extract TREs in DNA sequences of ###Dictyostelium discoideum (D.discoideum). Extracting characteristic patterns in DNA sequences is ###important to find TREs. We propose indices (Score M, Score T) to extract characteristic patterns in ###D.discoideum. Score M is proposed to extract patterns appeared in common region of DNA ###sequences. Score T is proposed to extract repeated patterns in common region of DNA sequences. ###Characteristic patterns according to Score M and Score T are extracted from non-transcribed ###region of Dictyostelium discoideum. The experimental Result shows that Score M and Score T are ###effective to extract targeted patterns.

Abstract ###It is important clarifying the function of the gene to extract exon, because exon is translated into the ###protein. In this laboratory has worked on the research of an automatic extraction of exon by using genetic ###programming (GP) and neural net work (NN). In this research, it has automatic of exon of human genome ###extracted it by using HMM as a comparison technique with these techniques. As a result, the identification ###accuracy of GT boundary became 90.7% and the identification accuracy in the AG boundary became 84.8%. ###Moreover, the comparison verification was done with HMM, GP, and NN.

Abstract ###The distortion of signal wave form is a major problem in higher frequency of signals on ###printed circuit board. To overcome this problem, the idea which changes transmission line width ###and positively using the reflection wave was proposed. However, it is difficult to apply realistic ###scale circuit because that method needs a lot of parameters. Thus, we propose the idea to reduce ###parameters and develop the method which decides parameters using GA. Next, we design actual ###clock line with a memory module and evaluate our new method.

ABSTRACT ###Recently, PC clusters are usually used in many laboratories in universities and departments in com-###panies. However these small scale PC cluster systems do not have software to manage jobs and tasks. ###So the management of PC cluster system is one of the complicated work for system administrators. To ###simplify the cluster management, we developed a web-based, client independent PC cluster manage-###ment system "CASPER". Since CASPER is made by the open-source software, it can work on many ###platforms. And it only requests the computers consisting the PC cluster use the unix-based operating ###system. The usability of CASPER was evaluated by questionnaires.

Abstract ###Surfers prefer a certain range of wave height so that they can ride on waves. It is a waste of ###time for them to go to seashore, when the waves are too low or high. Development of ###forecasting system has been expected to evade wasting time. Insufficient accurate data and ###complicated relations between wave height and factors make us choose fuzzy logic. ###A forecasting system is proposed, inputs of which are wave height and wind velocity of the ###previous day and wind velocity of the previous night, and the fuzzy rules of which are obtained ###from experts' know-how. The validation test using past two-year data at Kizakihama in ###Miyazaki leads us to the conclusion that the system realizes 86% forecast accuracy.

Melanophore-stimulating hormone (MSH) has been shown to be associated with food intake in addition to body color change in teleosts. MSH is encoded by a proopiomelanocortin (POMC) gene together with endorphin (END). To assess the significance of MSH to biological activities, we determined the structure and evaluated the expression of POMC mRNA in barfin flounder (bf), Verasper moseri, a member of a group of teleosts, Pleuronectiformes. Three subtypes of POMC cDNAs (A, B, and C) were amplified from bf pituitary glands. These bfPOMCs contained segments for N-POMC, α-MSH, β-MSH, and β-END as do other teleost POMCs, while POMC-C showed remarkable variations in the segments corresponding to N-POMC and β-END. A phylogenetic tree of ray-finned fish POMCs constructed by the neighbor joining method revealed that the three POMC subtypes may have appeared as a result of duplication events occurring at least twice during the course of bf evolution. The first duplication may have generated the lineage leading to an ancestor of bfPOMC-A and -B and that leading to bfPOMC-C, and then the lineage of bfPOMC-A may have diverged from that of bfPOMC-B. All peptides flanked by processing signals excluding N-POMC-C (1-14) were identified in a single pituitary extract by mass spectrometry, and the cDNAs of three POMCs were amplified from a single pituitary by reverse transcription polymerase chain reaction. These results demonstrated that the three POMC genes are expressed in a single individual. While the bfPOMC-A gene was exclusively expressed in the pituitary, the bfPOMC-B and -C genes were expressed in non-pituitary tissues such as brain, gill, heart, spleen, liver, stomach, intestine, testis, muscle, blood, and skin in addition to the pituitary. The expression levels of the POMC-A, -B, and -C genes in pituitary neurointermediate lobe were greater in the fish reared with a black background than the fish reared with a white background, indicating that MSH derived from all of the three bfPOMC genes was associated with body color change. No difference was observed in the expression levels of bfPOMC-C in the brain in response to feeding status. © 2005 Elsevier Inc. All rights reserved.
