As more and more researchers begin to analyse the dynamics characteristics of high-degree-of-freedom and nonlinear vehicle models, it is very important and valuable to propose a new analysis method for this type of model. Moreover, it is a promising research direction to propose quantitative indicators for analysing global vehicle dynamics. Therefore, on the basis of classic works, this paper proposes and verifies a quantitative analysis method - dissipation of energy method for 5-DOF nonlinear vehicle plane motion model for the first time. The quantitative indicators for vehicle nonlinear dynamics is expanded. The transfer relationship between the energy components is revealed, which shows that the dissipation of energy method can reflect the dynamics characteristics and stable region characteristics of the nonlinear 5-DOF vehicle system. The effects of tire force lateral-longitudinal coupling and driving modes on global dynamics are analysed. Finally, the prospect of this method is discussed.
Implementing 1 → <i>M</i> economical phase-covariant cloning and telecloning in cavity QED
Meng, Fanyu,Zhu, Aidong,Yeon, Kyu-Hwang,Yu, Seong-Cho IOP Pub 2009 Journal of Physics B: Atomic, Molecular and Optica Vol.42 No.16
<P>We propose a scheme to implement 1 → <I>M</I> economical phase-covariant quantum cloning by using <I>N</I> three-level atoms nonresonantly interacting with a cavity assisted by a classical laser field. Using this interaction 1 → <I>M</I> telecloning is also implemented by applying the maximal entangled <I>W</I> state and partial entangled <I>W</I> state as the quantum channel, respectively. It is pointed out by analysing the fidelities and success probabilities that a relatively high fidelity and success probability can be obtained by choosing an appropriate channel in terms of the pre-known information of the input state.</P>

Objective: This study aimed to investigate the effects of enrichment resources (a perch, dustbath, and nest) layout in furnished laying-hen cages (FC) on exterior quality of eggs. Methods: One hundred and sixty-eight (168) Hy-Line Brown laying hens at 16 weeks of age were randomly distributed to four treatments: small furnished cages (SFC), medium furnished cages type I (MFC-I), medium furnished cages type II (MFC-II), and medium furnished cages type III (MFC-III). Each treatment had 4 replicates or cages with 6 hens for SFC (24 birds for each SFC) and 12 hen/cage for MFC-I, -II, and -III (48 birds for each MFC-I, -II and -III). Following a 2-week acclimation, data collection started at 18 weeks of age and continued till 52 weeks of age. Dirtiness of egg surface or cracked shell as indicators of the exterior egg quality were recorded each week. Results: The results showed that the proportion of cracked or dirty eggs was significantly affected by the FC type (p<0.01) in that the highest proportion of cracked or dirty eggs was found in MFC-I and the lowest proportion of dirty eggs in SFC. The results of this showed that furnished cage types affected both dirty eggs and cracked eggs (p<0.01). The results also indicated that not nest but dustbath lead to more dirty eggs. Only MFC-I had higher dirty eggs at nest than other FC (p<0.01). The results of dirty eggs in MFC-I and MFC-II compared with SFC and MFC-III seemed suggest that a low position of dustbath led to more dirty eggs. Conclusion: SFC design affected exterior egg quality and the low position of dustbath in FC resulted in higher proportion of dirty eggs.

NAC proteins in plants respond to stress and play an important role in plant growth regulation. This regulation occurs through a variety of downstream eff ects mediated by plant hormones in response to stress. In this study, we performed a systematic genome-wide analysis of the NAC gene family in tomato based on genome version SL4.0. We identifi ed 99 SlNAC genes by abiotic stress analysis of conserved motifs and gene structure, phylogenetic analysis, cis-element analysis, chromosome localization analysis, synteny relationship and expression pattern analysis. These 99 SlNAC genes were distributed on all 12 chromosomes. Except for genes without introns, there was no signifi cant correlation between gene structures and phylogenetic relationships. Most of the cis-elements identifi ed were associated with plant hormones and environmental responses. There were 77 SlNAC genes that showed no homogeneity between tomato and wild rice, suggesting that these homologous genes arose after the diff erentiation of dicotyledonous and monocotyledonous plants. The comprehensive analysis of the SlNAC gene family provides a valuable resource for studying this gene family in tomato and a foundation for further study of the functional characteristics of these genes.
