Magnetic Nano-Particles and Their Applications in Immunoassays
Horng Herng-Er,C. C. Wu,Hong Chin-Yih,Liao S.H.,Liu C.M.,Yang S.Y.,Yang H.C. 한국물리학회 2006 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.48 No.5I
Biocompatible magnetic nano-particles show great potential in bio-magnetic applications, such as MRI contrast agents, drug delivery, magnetically labeled immunoassays, and so on. In this work, the feasibility of magnetically labeled immunoassay using bio-compatible magnetic nano-particles is investigated. To do this, we study the synthesis technologies for magnetic nano-particles of Fe3O4, as well as the coating of various bio-probes onto the magnetic nano-particles to detect the bio-targets avidin, such as, etc. Furthermore, different measurements, like magnetic relaxation and saturated magnetization, for the amounts of bio-targets are developed. In order to achieve an ultra-high sensitivity in magnetically labeled immunoassays, we used SQUIDs because SQUIDs are the most sensitive sensors for magnetic signals. The characterizations of these magnetically labeled immunological measurements are discussed.

CUSTOMER REACTIONS TO BRAND NAME REDEPLOYMENT AFTER M&A – THE MODERATING EFFECT OF M&A TYPE
Horng-Der Leu,Hsiao-Fang Hsu 글로벌지식마케팅경영학회 2014 Global Marketing Conference Vol.2014 No.7
In the context of M&A, how to redeploy two corporate assets is one of important organizational tasks. Among tasks, the management of intangible assets – in particular of corporate brand name is a critical element reflects consumers’ response. There has been increasing interest in the role of corporate names in academic fields. However, little attention has been paid to the different name and symbol options on M&A types. No empirical research has yet addressed branding strategies between in-market and cross-market M&A from the individual customers’ perspectives of acquired company. This paper seeks to address the research gap, by exploring acquired company customer on brand identity options in the context of post merger. Specifically, it considers the degree to which name and symbol influence acquired consumer responses. Thus, 5(brand strategy: target-dominant brand name A, acquirer-dominant brand name B, acquirer-dominant synergistic brand name BA, target-dominant synergistic brand name AB or create new brand name C) × 2(M & A types: in market or cross-market) between subject experiment design was conducted. 494 undergraduate or graduate students are the subjects from a college. Questionnaires were collected by convenience sampling. The results show that: (1). Brand name redeployment strategy has significant effect on customers’ sovereignty deprivation and brand switching intention. (2). In in-market M&A type situation, target-dominant brand tend to outperform acquirer-dominant brand strategy in decreasing the degree of acquired company customers’ perceived sovereignty deprivation and brand switching intention when compared with cross-market M&A type. (3). In in-market M&A type situation, new brand tend to outperform acquirer-dominant brand strategy in decreasing the degree of acquired company customers’ perceived sovereignty deprivation and brand switching intention when compared with cross-market M&A type. (4). In in-market M&A type situation, acquirer-dominant synergistic brand strategy tend to outperform new brand strategy in decreasing the degree of acquired company customers’ perceived sovereignty deprivation when compared with cross-market M&A type. In summary, in in-market M&A type situation, acquirer-dominant synergistic brand is the best strategy and new brand name is the second best option in decreasing the degree of acquired company customers’ perceived sovereignty deprivation when compared with cross-market type situation. The results should guide managers regarding post-M&A branding strategies.

LuGre Model-Based Neural Network Friction Compensator in a Linear Motor Stage
Horng, Rong-Hwang,Lin, Li-Ren,Lee, An-Chen Korean Society for Precision Engineering 2006 International Journal of Precision Engineering and Vol.7 No.2
This paper proposes a LuGre Model-Based Neural Network (MBNN) friction compensation algorithm for a linear motor stage. For matching the friction phenomena in both the motion-start region and the motion-reverse region, the LuGre dynamic model is employed into the proposed compensation algorithm. After training of the model-based neural network is completed, the estimated friction for compensation is obtained. From the obtained result we find that the new structure gains advantage over the non-friction compensation system on the performance of the compensator in both regions. The proposed compensator is evaluated and compared experimentally with an uncompensated system on a microcomputer controlled linear motor tracking system in the final section of the paper. The experimental results show the improvement on the maximum velocity error and the root mean square tracking error in the motion-start region ranges from 34% to 53% and from 53% to 75% respectively, and in the motion-reverse region from 48% to 65% and from 79% to 90% respectively.

Background/Aims: In endoscopic submucosal dissection (ESD) training, only a flat target lesion can usually be simulated in the normal mucosa. This study aimed to evaluate the feasibility of simulated targets in the stomachs of live pigs for complete training. Methods: Six trained endoscopists with hands-on experience with ex vivo, isolated pig stomachs were enrolled in this pilot study. An endoscopic banding device was used to create a polyp that was snared, leaving an ulcerated lesion. This simulated target model was used to perform ESD in pigs. The en bloc resection rate, procedure time, complications, quality of resection, and participants` opinions on the simulated targets were compared with the conventional model. Results: En bloc resections were achieved in all six simulated targets and six conventional models. The mean size of the resected specimens was 32.2 mm (range, 20 to 39 mm) in the simulated target group and 23.5 mm (range, 11 to 40 mm) in the conventional group. The target model had a high quality of resection and had a high satisfaction rate for margin identification and correct peripheral marking. Conclusions: Good identification of the lesion and ease of periphery marking in the target model may improve resection quality. (Gut Liver 2014;8:619-624)

Performance Evaluation of Packet Radios with Finite Population under Multipath Interference
Jyh -Horng Wen,Di-Yar Han 에스케이텔레콤 (주) 1998 Telecommunications Review Vol.8 No.5
This paper proposes a three-dimensional Markov model to study the effect of multipath interference on packet radios with a finite population. With this Markov model and minislot approximation, the system performance in terms of throughput and delay is evaluated. Computer simulations are performed to verify the correctness of the analytical method. In addition, an extended-slot method is also proposed to reduce the multipath interference triggered by line-of-sight packets in the preceding slot. Numerical results show that the proposed method remarkably enhances system performance.

The issue of capacity constraint resources (CCR) or bottlenecks wandering in product mix decision by applying Theory of Constraints (TOC) management philosophy has been mentioned and demonstrated in several papers. In this study, the effect for prolonging the planning period (PPP) so as to stabilize the CCR is investigated. The results show that the effect for PPP alternative will be positive or negative which is depending on the environment condition. However, a majority cases which have positive effect for PPP alternative can be recognized prior knowing the marketing demand, which is significant in the real application.
