Objective: Vertebral compression fractures (VCFs) are common complications of osteoporosis. The expansion of VCFs with a Sky Bone Expander is a new procedure which improves kyphotic deformities and decreases pain associated with VCFs. The purpose of this study was to investigate the preliminary results for the treatment of painful osteoporotic VCFs with a Sky Bone Expander. Materials and Methods: Twenty-six patients with pain-causing VCFs were treated with a Sky Bone Expander. This operation involved the percutaneous insertion of the Sky Bone Expander into a fractured vertebral body transpedicularly. Following the expansion, the Sky Bone Expander was contracted and removed, resulting in a cavity to be filled with bone cement. All fractures were analyzed for improvement in sagittal alignment. Clinical complications, pain relief and ambulation status were evaluated 1 day, 1 week, 1 month, and 3 months after the operation. Results: Twenty-four hours after the operation, all the patients treated experienced some degree of pain relief. In addition, no postoperative neurologic complications were noted. The average operative time was 42.4 ± 15.5 min per vertebra. Moreover, an average cement volume of 3.5 mL (range, 2.5 ± 5.0 mL) was injected per vertebra. The average anterior height was 18.4 ± 5.1 mm preoperatively and 20.5 ± 5.3 mm postoperatively (p < 0.01). Furthermore, the average midline height was 15.5 ± 5.2 mm preoperatively and 18.9 ± 4.0 mm postoperatively (p < 0.01). The Cobb angle improved from 18.5 ± 8.2 degrees preoperatively to 9.2 ± 4.0 degrees postoperatively (p < 0.01). The Visual Anabog Scale scores decreased from 7.7 ± 1.8 points preoperatively to 3.1 ± 2.0, 2.9 ± 1.7, 2.6 ± 1.5 and 2.9 ± 11.3 after 1 day, 1 week, 1 month and 3 months after the operation, respectively. Cement extrusion was observed in four patients without any neurologic symptoms. Conclusion: As a result of this study, we can postulate that the expansion of compressed vetrebra with a Sky Bone Expander is a safe and minimally invasive procedure resulting in the restoration of vertebral body height and the relief of pain associated with VCFs.

Detection of epistatic interaction of two QTLs, <i>gw8.1</i> and <i>gw9.1</i>, underlying grain weight using nearly isogenic lines in rice

<P>Grain weight (GW) is one of the most important targets for grain yield in rice breeding. In previous studies, two quantitative trait loci (QTLs) for GW, <I>gw8.1</I> and <I>gw9.1</I>, have been identified using progeny derived from a cross between the <I>japonica</I> cultivar Hwaseong and <I>Oryza rufipogon </I>(IRGC 105491). To test whether these quantitative trait loci (QTLs) have an epistatic interaction, we developed an F<SUB>2</SUB> population by crossing two nearly isogenic lines (NILs) harboring <I>gw8.1</I> and <I>gw9.1</I>. Simple sequence repeat (SSR) markers tightly linked to the QTLs were used to select F<SUB>3</SUB> QTL-NILs from the F<SUB>2</SUB> population. A two-way ANOVA revealed an epistatic interaction between the two QTLs in the F<SUB>2</SUB> population (<I>P</I> = 0.0084). This interaction was confirmed by an analysis of F<SUB>3</SUB> QTL-NILs indicating that both QTLs are involved in the same genetic mechanism controlling GW. The <I>gw8.1</I> QTL was further mapped between two SSR markers, RM23204 and RM23211, which are 110.1 kb apart. To our knowledge, this is the first report using QTL-NILs to reveal an epistatic interaction between QTLs for GW.</P>

Pyramiding of 2 QTLs, gw8 and gw9, underlying grain weight using nearly isogenic lines (NILs) in rice

Feng-Xue Jin,Xiao-Bo Xie,Shi-Dong Ji,Hong-Guang Ju,Jung-Pil Suh,Hung-Goo Hwang,Sang-Nag Ahn 한국작물학회 2008 한국작물학회 학술발표대회 논문집 Vol.2008 No.10

Grain weight (GW) or grain size is the most important target not only as a major component of grain yield, but also associated with the cooking quality in rice breeding program. In a previous study, two loci for grain weight, gw8 and gw9, have been fine map to about 306.4kb and 37.4kb, respectively, in backcross populations derived from a cross between the Korean japonica cultivar Hwaseongbyeo and Oryza rufipigon (IRGC 105491). Both O.rufipogon alleles increased GW in the Hwaseongbyeo background despite the fact that O. rufipogon was the small-seeded parent. To test the effect of pyramiding the QTLs for grain weight, an F2 population consisted of 226 individuals was developed derived from the cross between the two QTLs (gw8 and gw9), and used MAS to select nearly isgenic lines for two QTLs and a pyramiding line. Molecular genotyping of F2 population revealed the existence of interaction between gw8 and gw9. Moreover, the interaction was also confirmed by phenotypic analysis of four QTL-NILs. The results suggest that epistasis interaction is important genetic basis in determining yield traits in rice.

A damage localization method based on the singular value decomposition (SVD) for plates

Zhi-Bo Yang,Jin-Tao Yu,Shao-Hua Tian,Xue-Feng Chen,Guan-Ji Xu 국제구조공학회 2018 Smart Structures and Systems, An International Jou Vol.22 No.5

Boundary effect and the noise robustness are the two crucial aspects which affect the effectiveness of the damage localization based on the mode shape measurements. To overcome the boundary effect problem and enhance the noise robustness in damage detection, a simple damage localization method is proposed based on the Singular Value Decomposition (SVD) for the mode shape of composite plates. In the proposed method, the boundary effect problem is addressed by the decomposition and reconstruction of mode shape, and the noise robustness in enhanced by the noise filtering during the decomposition and reconstruction process. Numerical validations are performed on plate-like structures for various damage and boundary scenarios. Validations show that the proposed method is accurate and effective in the damage detection for the two-dimensional structures.

The evolution property of four-body concurrence in Jaynes-Cummings model

Xing-Ri JIN,Shou ZHANG,Bo-Xue LIU,Chung-In UM,Kyu-Hwang YEON 한국물리학회 2005 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.46 No.4

We realized the four-body approximate W state by the interaction of two atoms and two mode vacuum cavity fields, no matter that the two atoms are initially in Einstein-Podolsky-Rosen entangled states or in disentangled states. The four-body entanglement changes with the initial state of the system and the detuning degree. What’s important is that when the two atoms are initially in Einstein-Podolsky-Rosen, the entanglement of atom-atom and field-field can reach a maximal value of 1. Also if the two atoms are initially in disentangled tates, the entanglement of atom-atom andfield-field won’t go beyond 1/2.

JointMulti-innovation Recursive Extended Least Squares Parameter and State Estimation for a Class of State-space Systems

Ting Cui,Feng Ding,Xue-Bo Jin,Ahmed Alsaedi,Tasawar Hayat 제어·로봇·시스템학회 2020 International Journal of Control, Automation, and Vol.18 No.6

The relationship between the parameters and the states of state-space systems is nonlinear, which makes the identification problems of state-space systems complicated. This paper considers the joint parameter and state estimation issues for a class of state-space systems in the observer canonical form with the process noises and the observation noises. By means of the least squares principle and the Kalman filtering, we derive a Kalman filtering based recursive extended least squares algorithm. For purpose of achieving the higher estimation accuracy, a Kalman filtering based multi-innovation recursive extended least squares algorithm is proposed by utilizing a range of available data and more information at each recursion. Finally, the effectiveness of the proposed algorithms is validated through a simulation example.

Dynamic Guaranteed Cost Compression for Time Series Big Data

Miao Bei-bei,Jin Xue-bo 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.4

Most time series big data is with noise and uncertain. To abstract the key information effectively and quickly, the estimation is one of the feasible methods for the uncertain big data. The Kalman filter with adaptive method by part of samples can give the high dimensional characteristics, reduce the computing cost and data uncertainty, but encounter the irregular estimation. The number of sample and the performance of the abstracted information have the tradeoff, which means we can use the suitable number of sample to abstract the key information of the series data. This paper discusses how to find the suitable sampling points for the time series data and the simulations show that the key dynamic information of time series big data can be guaranteed with the compression amount number of sample data.
