Activity-dependent alterations in the strength of an individual glutamatergic synapse are often accompanied by changes in the size and shape of the postsynaptic terminal. Two studies in this issue of Neuron, Meyer et al. (2014) and Bosch et al. (2014), shed new light on the mechanisms and signaling pathways underlying structural long-term potentiation.

geometric morphometric method was used to examine body shape variations among all the seven valid species of the genus alburnus in iran. in total 409 specimens of a. chalcoides, a. filippii, a. atropatenae, a. caeruleus, a. mossulensis, a. hohenackeri and a. zagrosensis were collected from babolrud, baleqlu-chai, miriseh, sarabeleh, gamasiyab, mahabad-chai rivers and the gandoman lagoon, respec...

the present study is concerned with optimal shape determination of inhomogeneous and temperature dependent domains under steady state heat conduction. such situations are important in many thermal design problems, especially in shape design of electronic components and chips. in the present paper, we formulate the shape optimization problem based on volume minimization of heat conductive materi...

the phase transformation phenomenon due to the crystallographic change of shape memory alloys subjected to mechanical or thermal loading is very complicated. regarding the thermo-mechanical coupling effects in shape memory alloys, in case of high  loading rates, heat generation/absorption during the forward/reverse transformation, will lead in temperature-dependent variation and consequently af...

The flexibility and curvature of duplex DNAs containing mismatched sites have been monitored as a function of temperature. The diffusion coefficients are dependent on the flexibility and the curvature of the DNA, and these have been determined by NMR-based methods. The diffusion coefficients, D, depend on a Boltzmann term and the viscosity of the solvent, eta, which is also temperature dependen...

The alignment between the inertialess spheroids and directions of fluid Lagrangian stretching or compression is sensitive to particles shape near wall but not center channel [Cui et al. “Alignment statistics rods with direction in a flow,” J. Fluid Mech. 901, A16 (2020)]. This observation further investigated current study uncover mechanism particle behavior different regions flows at Reτ≈180 1...
