Fiber bundles for imaging internal organs with minimum physical damage have been increasingly developed for both basic life sciences and clinical applications. Reflectance imaging is possible using fiber bundles for detecting the intrinsic optical contrast of blood vessels and tissue structure. The placement of an illumination source adjacent to imaging optics causes scattered light from deeper tissue layers to illuminate superficial tissues and results in a reflectance image. However, it does not have focal capacity and lacks depth resolution. In this study, we performed spatial analysis for the vertical reconstruction of in vivo tissues using a multipositional illumination scheme. The observed image corresponded to the “shadow” of a target object. When we manipulated the location of illumination, the shadow moved horizontally depending on the depth of the target. We used this horizontal displacement as a cue and successfully performed the vertical reconstruction of mouse brain blood vessels.

The LUC4,6 cryptosystem is a system analogy with RSA cryptosystem and extended from LUC and LUC3 cryptosystems. The process of encryption and decryption are derived from the fourth order linear recurrence sequence and based on Lucas function. This paper reports an investigation into the common modulus attack on the LUC4,6 cryptosystem. In general, the common modulus attack will be succeeded if the sender sends the plaintext to two users used same RSA-modulus and both of encryption keys of them are relatively prime to each other. However, based on the characteristics of high order Lucas sequence, the LUC4,6 cryptosystem is unattackable

Several contributions of the Thrace group to magnetospheric, solar, and planetary physics over the last three decades are summarized from the perspective of a paradigm shift in nonlinear plasma physics. The work by Dennis Papadopoulos on plasma instabilities has been a source of inspiration for our magnetospheric studies including the introduction of the chaos hypothesis.

Evaluating Simulation Heuristics in Monte‐Carlo Tree Search and its Application to a Production Scheduling

This paper reports simulation heuristics of Monte‐Carlo Tree Search (MCTS) and shows an application example. MCTS introduced by Coulom is a best‐first search where pseudorandom simulations guide the solution of problem. Recent improvements on MCTS have produced strong computer Go program, which has a large search space, and the success is a hot topic for selecting the best move. So far, most of reports about MCTS have been on two‐player games, and MCTS has been used rarely for one‐player perfect‐information games. MCTS does not need admissible heuristic, so the application of MCTS for one‐player games might be an interesting alternative. Additionally, one‐player games like puzzles are determinately operated only by one player’s decision, so the sequences of changes in state are describable as a network diagram with interdependence between operations. If MCTS for one‐player games is available as a meta‐heuristic algorithm, we can use this algorithm for not only combinatorial optimization problems, but also many practical problems. Especially, as MCTS does not fully depend on evaluation function, so the solutions based on MCTS remain effective if objective function is modified. This paper firstly investigates on the application of Single Player MCTS (SP‐MCTS) introduced by Schadd et al. to a puzzle game called Bubble Breaker. Next this paper shows the effectiveness of new simulation strategies of SP‐MCTS, and considers the differences between each parameter. Based on the results, this paper discusses the application potentiality of SP‐MCTS for a scheduling problem.

A k‐regular hamiltonian and hamiltonian connected graph G is optimal fault‐tolerant hamiltonian and hamiltonian connected if G remains hamiltonian after removing at most k−2 nodes and/or edges and remains hamiltonian connected after removing at most k−3 nodes and/or edges. In this paper, we investigate a construction scheme to construct optimal fault‐tolerant hamiltonian and hamiltonian connected graphs. Hence, some of the generalized hypercubes, Twisted‐cubes, Crossed‐cubes, and Möbius cubes are optimal fault‐tolerant hamiltonian and optimal fault‐tolerant hamiltonian connected.

AIP Conference Proceedings 2008年第1期1052卷 177-181页

In this study, we carried out development of non‐invasive optical transcutaneous partial pressure of carbon dioxide, pCO2, monitoring system. The purpose of this system is to detect CO2 from outer skin, not from the arterial blood‐gathering method. There are advantages about a reduction of analysis time and real‐time monitoring that this system might be available. The measurement system is composed of the IR lamp, the pyroelectric sensor including a 4.26 μm optical filter, the optical gas reaction chamber and the signal processing circuit. The optical reaction length of chamber was reduced by 1 mm using the soft‐lithography method which CO2 is exhausted in human body as we considered. The fabricated pCO2 monitoring system showed linear result of 6.50×10−6 absorbance/ppm sensitivity for CO2 concentration from 0 ∼5,000 ppm by MFC and about 2 seconds of fast response time. The proposed system can be used in the optical biosensor field for the medical diagnosis such as pCO2 monitoring system and environment monitoring systems.

Approximation algorithms of non‐unique probes selection for biological target identification

引用

AIP Conference Proceedings 2007年第1期953卷 174-184页

作者： My T. Thai Ping Deng Weili Wu Taieb Znati aDepartment of Computer and Information Science and Engineering University of Florida Gainesville FL 32611 bDepartment of Computer Science University of Texas at Dallas Richardson TX 75083 cDepartment of Computer Science University of Pittsburgh Pittsburgh PA 15215

Non‐unique probes are used to identify the targets, i.e., viruses, present in a given sample. Since the number of selected non‐unique probes is equal to the number of hybridization experiments, it is important to find a minimum set of non‐unique probes, which is NP‐complete. Using d‐disjunct matrix, we present two (1+(d+1)logn)‐approximation algorithms to identify at most d targets. Based on our selected non‐unique probes, we also present the decoding algorithms with linear time complexity. In addition, our solutions are fault tolerant. The proposed algorithms can identify at most d targets in the presence of experimental errors.

TIM Barrel Protein Structure Classification Using Alignment Approach and Best Hit Strategy

引用

AIP Conference Proceedings 2007年第1期952卷 177-186页

作者： Jia‐Han Chu Chun Yuan Lin Cheng‐Wen Chang Chihan Lee Yuh‐Shyong Yang Chuan Yi Tang aDepartment of Computer Science National Tsing Hua University Hsinchu Taiwan cDepartment of Computer Science and Information Engineering Chang Gung University TaoYuan Taiwan bInstitute of Biochemical Engineering College of Biological Science and Technology National Chiao Tung University Hsinchu Taiwan

The classification of protein structures is essential for their function determination in bioinformatics. It has been estimated that around 10% of all known enzymes have TIM barrel domains from the Structural Classification of Proteins (SCOP) database. With its high sequence variation and diverse functionalities, TIM barrel protein becomes to be an attractive target for protein engineering and for the evolution study. Hence, in this paper, an alignment approach with the best hit strategy is proposed to classify the TIM barrel protein structure in terms of superfamily and family levels in the SCOP. This work is also used to do the classification for class level in the Enzyme nomenclature (ENZYME) database. Two testing data sets, TIM40D and TIM95D, both are used to evaluate this approach. The resulting classification has an overall prediction accuracy rate of 90.3% for the superfamily level in the SCOP, 89.5% for the family level in the SCOP and 70.1% for the class level in the ENZYME. These results demonstrate that the alignment approach with the best hit strategy is a simple and viable method for the TIM barrel protein structure classification, even only has the amino acid sequences information.
