Objective: The aim of this study was to evaluate the effects of three feeding systems, i.e., indoor feeding (CON), indoor feeding with 4-h daily access to grazing artificial pasture (ITGP), and indoor feeding with 8-h daily access to grazing artificial pasture (IEGP), on the plasma antioxidant and immunological capacity, slaughter characteristics, meat quality and economic efficiency of Huang-huai lambs. Methods: Thirty-three healthy Huang-huai rams with similar body weight (approximately 5 mo of age, 28.96±1.01 kg) were assigned equally to three experimental groups. When finished fattening, six lambs from each group were collect blood samples for plasma analyses and then slaughtered to determine slaughter characteristics and obtain biceps brachii muscle for further analysis of meat quality and fatty acid profile. Results: Compared to CON group, animals submitted to ITGP and IEGP groups resulted in greater contents of serum glutathione peroxidase, immunoglobulins (IgA, IgG, and IgM), polyunsaturated fatty acids (PUFA), n-6 PUFA, and PUFA/saturated fatty acid (FA) ratio and lower palmitic /oleic acid ratio (p<0.05). Moreover, animals in ITGP group exhibited a higher (p<0.05) loin eye area, content of meat crude protein (CP), and eicosetrienoic acid compared to CON group, while slaughter performance was superior (p<0.05) to that of the IEGP group. The economic efficiency of ITGP group was 70.12% higher than that of CON group, while the IEGP group exhibited a decrease of 92.54% in economic efficiency compared to the CON group. Conclusion: Restricted grazing time combined with indoor feeding was more effective in conferring superior body health, carcass traits and economic efficiency in Huang-huai lambs, as well as higher CP content and healthier FA composition in the resulting meat.
COMPLETELY GENERALIZED MILDLY NONLINEAR COMPLEMENTARITY PROBLEMS FOR FUZZY MAPPINGS
Huang, Nan-Jing,Zhang, Wen-Bin 한국전산응용수학회 1997 Journal of applied mathematics & informatics Vol.4 No.2
In this paper we introduce and study a new class of completely generalized mildly nonlinear complementarity problems for fuzzy mappings and construct some new iterative algorithms. We also show the existence of solution and the convergence of iterative sequences generated by the algorithm. Our results extend some recent results of Noor, Chang and huang.

We present a unique global solvability and flocking estimate of an entropic weak solution to the one-dimensional pressureless Euler system with a flocking dissipation in all-to-all coupling setting. This model appears naturally as a quasi-equilibrium model for hydrodynamic description of Cucker-Smale flocking. For the unique global solvability, we adopt the variation approach from Ding and Huang's work [19] on the inhomogeneous pressureless gas dynamic model. When initial mass and velocity are locally integrable and bounded measurable functions, respectively, we give explicit representations for the global entropic weak solutions. Our results do not require any smallness of initial data except that initial mass density is almost everywhere positive.

This study is intended to investigate the fundamental properties of cement mortar with solid content and leaving time of recycled water that stabilizing agent is added. According to the results, fluidity and air content does not make a big difference with variation of solid content. As the leaving time of recycled water is long, fluidity and air content increases. Setting time is shortened due to fine particle with an increase of solid content and leaving time. Compressive strength and flexural strength increase with an increase of solid content, and they increase at the leaving time of 1 day, but decrease after 2days. Length change by drying shrinkage is smaller than that of plain concrete, and is almost same with variation of solid content. And it is reduced at the leaving time of 1 day, but increases after that. Therefore, it analyzed that the effect of stabilizing agent is best under condition of adding ratio of 0.15%, solid content of 3% and leaving time of 1day, and it also works upto solid content of 5% and leaving time of 2days.

Carbon disulfide (CS2), a common organic solvent, induces a variety of adverse effects in the male reproductive system. In this study, we investigated the cytotoxicity, ultrastructural changes, and potential apoptotic induction mechanisms of CS2 in mixed cultures of Sertoli and germ cells. Sertoli and germ cells were cocultured and treated with CS2 for 24 h. Growth rates were noted, and apoptotic cells were identified by Hoechst 33258 staining. Ultrastructure changes were observed via transmission electron microscopy (TEM). Mitochondrial membrane potential and expressions of apoptosis-related factors (cytochrome c, Bax, Bcl- 2, caspase-3 and caspase-9) were examined by JC-1 staining, western blot, and real-time PCR. The results showed that CS2 treatment was associated with reduced growth rates of Sertoli-germ cells. Ultrastructure changes in Sertoli-germ cells treated with CS2 were typical of apoptosis. In addition, CS2 treatment depolarized mitochondrial membrane potential, upregulated Bax levels and downregulated Bcl-2 levels, released cytochrome c from the mitochondrial intermembrane space to the cytosol, and triggered mitochondria-mediated apoptosis. Subsequently, caspase-9 and caspase-3 were activated, resulting in Sertoli-germ cells apoptosis. The above data suggest that CS2 has adverse effect on the viability of Sertoli-germ cells and induces apoptosis through mitochondrial pathway.
ON THE END EXTENDING IN THE HILBERT-HUANG TRANSFORM
Da Ji Huang,Jin Ping Zhao,Ji Lian Su 한국해안해양공학회 1999 학술강연회 발표논문초록집 Vol.1 No.1
Hilbert-Huang transform is powerful method of nonlinear and non-stationary time series analysis. Two approaches, mirror periodic and extrema extending method, have been developed for handling the end effects of Hilbert-Huang transform. The mirror periodic method is based on the data distribution at ends. Two mirrors are placed at the extrema of both ends. The data within the mirrors are extended with mirror reflection to obtain a periodic sequence. With this method, the end effects of empirical mode decomposition and Hilbert transform are solved once forever. The mirror periodic method can get best results by placed the mirrors at the extrema, which have symmetric property of the data. Extrema extending method is implemented by adding two maxima and minima at the ends, which are defined by the two consecutive extrema of the data at ends. It is easy to perform and has equally well behalf as mirror periodic method. The extrema method is superior to the mirror periodic method when the data has strong asymmetric waveform.
SEDUCING CUSTOMERS WITH FOND MEMORIES: THE EFFECT OF NOSTALGIA ON CONSUMER SWITCHING BEHAVIOR

Nostalgia refers to the sentimental longing for the valued past (Sedikides, Wildschut, & Baden, 2004). It is considered a bittersweet emotion, involving both wistful joy and sadness (Sedikides et al., 2004). Nostalgia is also a social emotion. Nostalgic memories typically center on social activities involving the self and close others (Wildschut et al., 2010). Prior research has mainly focused on the social and emotional nature of nostalgic narratives, and researchers have only recently started to investigate the motivations triggered by the process of recalling nostalgic narratives. For example, recalling a nostalgic event can heighten people’s motivation to savor such an experience and prolong it (Huang, Huang, & Wyer, 2016). In the current research, we posit that thinking about nostalgic events can trigger another motivation, namely, a desire to revive the past. Whenever people experience nostalgic feelings, they are likely to perceive differences between the present and their memorable past and desire to go back in time (Hepper et al., 2012; Sedikides et al., 2004). This motivation, once activated, can lead people to take actions to change their current state in the hope of reviving the past (Koole & Jostmann, 2004; Kuhl, 1985). This tendency of taking actions to make changes may generalize to subsequent unrelated situations (Kruglanski et al., 2002), and consequently increase consumer switching behavior (Jiang, Zhan, & Rucker, 2014). These predictions were tested across five studies in various consumption contexts. Our findings contribute to consumer research in two important ways, (a) by demonstrating a novel motivational impact of nostalgia on consumer behavior, and (b) by delineating a systematic influence of an unexplored but pervasive emotional factor— nostalgia—on consumer switching behavior. This research also offers practical implications. Conventional wisdom suggests that nostalgia can make consumers prefer products reminiscent of the “old days”. Our findings show that nostalgia can have broader implications for consumer choices and marketers may use it to manage consumer switching behavior.
