The effect of the radial heat conduction on the effective thermal conductivity of carbon nanotube(CNT) bundles is studied by the nonequilibrium molecular dynamics(NEMD) method. The hexagonal CNT bundle consists of seven(10, 10) single-walled carbon nanotubes(SWCNTs). The radial heat conduction is induced by creating the vacancy defects in some segments of the constituent CNTs. Combined with the temperature differences and the inter-tube thermal resistances at the different segments,the radial heat flow in the CNT bundle is calculated. The maximum percentage of the radial heat flow is less than 7% with the presence of four defective CNTs, while the resultant decrement of the effective thermal conductivity of the bundle is about 18%.The present results indicate that the radial heat flow can significantly diminish the axial heat conduction in the CNT bundles,which probably explains the smaller effective thermal conductivity in the CNT assemblies compared to that of the individual CNTs.

We study the electron states and the differential cross section for an electron Raman scattering process in a semi- conductor quantum well wire of cylindrical ring geometry. The electron Raman scattering developed here can be used to provide direct information about the electron band structures of these confinement systems. We assume that the system grows in a GaAs/Al0.35Ga0.65As matrix. The system is modeled by considering T = 0 K and also a single parabolic con- duction band, which is split into a sub-band system due to the confinement. The emission spectra are discussed for different scattering configurations, and the selection rules for the processes are also studied. Singularities in the spectra are found and interpreted.

While it is known that patatin-related phospholipase A （pPLA） activity is rapidly activated within 3min by auxin, hardly anything is known about how this signal influences downstream responses like transcription of early auxin-induced genes or other physiological responses. We screened mutants with T-DNA insertions in members of the pPLA gene family for molecular and physiological phenotypes related to auxin. Only one in nine Arabidopsis thaliana ppla knockdown mutants displayed an obvious constitutive auxin-related phenotype. Compared to wild-type, ppla-IIlδ mutant seedlings had decreased main root lengths and increased lateral root numbers. We tested auxin-induced gene expression as a molecular readout for primary molecular auxin responses in nine ppla mutants and found delayed up- regulation of auxin-responsive gene exRression in all of themL Thirty minutes after auxin treatment, up-regulation of up to 40% of auxin-induced genes was delayed in mutant seedlings. We observed only a few cases with hypersensitive auxin-induced gene expression in ppla mutants. While, in three ppla mutants, which were investigated in detail, rapid up- regulation （as early as 10 min after auxin stimulus） of auxin-regulated genes was impaired, late transcriptional responses were wild-type-like. This regulatory or dynamic phenotype was consistently observed in different ppla mutants with delayed up-regulation that frequently affected the same genes. This defect was not affected by pPLA transcript levels which remained constant. This indicates aposttranslational mechanism as a functional link of pPLAs to auxin signaling. The need for a receptor triggering an auxin response without employing transcription regulation is discussed.
