, 2012 Correlative light (LM) and transmission electron microscopic (TEM) analysis is useful, if ultrastructural details of cells need to be related to functional aspects which can only be examined at the LM level. The first protocol presented here introduces a relatively simple way of obtaining TEM images which, on the one hand, reveal ultrastructural ...

Bilepton Resonance in Electron-Electron Scattering [PDF]
, 2000 Theoretical backgound for bileptonic gauge bosons is reviewed, both the SU(15) GUT model and the 3-3-1 model. Mass limits on bileptons are discussed coming from $e^+e^-$ scattering, polarized muon decay and muonium-antimuonium conversion. Discovery in $e^

Crown-down preflaring in the determination of the first apical file
Brazilian Oral Research, 2010 In this study, scanning electron microscopy (SEM) was used to evaluate the adaptation of the first apical file after preflaring in mesiobuccal (MB) and mesiolingual (ML) canals of mandibular molars considering the tactile sensibility as a reference.

Role of electron-electron and electron-phonon interaction effect in the optical conductivity of VO2 [PDF]
, 2006 We have investigated the charge dynamics of VO2 by optical reflectivity measurements. Optical conductivity clearly shows a metal-insulator transition. In the metallic phase, a broad Drude-like structure is observed.

Electron hole capture centers in an irradiated K2SO4-Cu crystal
Eurasian Journal of Physics and Functional Materials, 2021 The methods of vacuum ultraviolet and thermal activation spectroscopy were used to measure the excitation spectra of impurity radiation in the fundamental absorption band of K2SO4-Cu crystals at 15 K and 300 K.

Electron-electron interaction in multiwall carbon nanotubes [PDF]
, 2001 Magnetic susceptibility $\chi$ of pristine and brominated arc-produced sample of multiwall carbon nanotubes was measured from 4.2 to 400 K. An additional contribution $\Delta \chi(T)$ to diamagnetic susceptibility $\chi(T)$ of carbon nanotubes was found ...

Electronic Markets and Electronic Hierarchies [PDF]
Communications of the ACM, 1987 Abstract The innovations in information technologies of the past two decades have radically reduced the time and cost of processing and communicating information. These reductions have in turn brought many changes in the ways that tasks are accomplished in firms.

On Emergent Particles and Stable Neutral Plasma Balls in SU(2) Yang-Mills Thermodynamics
Universe, 2022 For a pure SU(2) Yang–Mills theory in 4D, we revisit the spatial (3D), ball-like region of radius r0 in its bulk subject to the pressureless, deconfining phase at T0=1.32Tc, where Tc denotes the critical temperature for the onset of the deconfining ...
