The cingulum,the neural tract connecting the orbitofrontal cortex with the medial temporal lobe,plays an important role in cognition（Bush et al.,2000）.It is also important in memory because it provides cholinergic innervations to the cerebral cortex after obtaining innervation from the medial septal nucleus,the vertical nucleus of the diagonal band, and the nucleus basalis of Meynert via the medial cholinergic pathway （Nieuwenhuys et al., 2008; Naidich and Duvernoy, 2009; Hong and Jang, 2010a）.

The current status of 2D organic–inorganic hybrid perovskites for use in photovoltaic(PV)and light-emitting diode(LED)applications lags far behind their 3D ***,we propose a computational strategy for discovering novel perovskites with as few computing resources as possible.A tandem optimization algorithm consisting of an elitism-reinforced nondominated sorting genetic algorithm(NSGA-II)and a multiobjective Bayesian optimization(MOBO)algorithm was used for density functional theory(DFT)*** DFT-calculated band gap and effective mass were taken as objective functions to be optimized,and the constituent molecules and elements of a Ruddlesden–Popper(RP)structure(n=2)were taken as decision *** previously unknown RP perovskite candidates for PV and LED applications were discovered as a result of the NSGA-II/MOBO ***,more accurate DFT calculations based on the HSE06 exchange correlation functional and ab initio molecular dynamics(AIMD)were conducted for the discovered 2D perovskites to ensure their validity.

作者： dong Hun kim Sang-Chul Lee do-Yeon Kwak Kyeong-Yeoll Lee School of Applied Biosciences College of Agricultura and Life Sciences Kyungpook National University Daegu Yeongnam Agricultural Research Institute Milyang Republic of Korea

Three heat shock protein （HSP） genes （hsp70, hsc70, hsp90） were partially cloned from the brown planthopper Nilaparvata lugens and the small brown planthopper Laodelphax striatellus （Homoptera： Delphacidae）, which are serious pests of the rice plant. Sequence comparisons at the deduced amino acid level showed that the three HSPs of planthoppers were most homologous to corresponding HSPs of dipteran and lepidopteran species. Identities of both heat shock cognate 70 and HSP90 were higher than HSP70 in both species. Identity of the HSP70 between the two planthopper species was only 81%, a value much lower than seen among fly and moth groups. Effects of heat and cold shocks were demonstrated on expression of the three hsp genes in the two planthopper species. Heat shock （40 ℃） upregulated the hsp90 level but did not change the hsc70 level in either the nymph and adult stages of either species. On the other hand, the hsp70 level was only upregulated in L. striatellus. This heat shock response was prompt and lasted only for 1 h after treatment. In contrast, cold shock at 4℃ did not change the expression levels of any hsp in either species.
