TL;DR: In this article, an inversion pulse for wideband application is obtained from a simple nonlinear amplitude modulation wherein the amplitude is modulated in accord with A(t)=A 0 {1-| sin βt| n } and the entire pulse is frequency modulated such that the phase varies as φ(t) =φ 0 + 1/2 kt 2

TL;DR: Near optimal hole doping, the Fermi surface is large and consistent with band calculations, and in underdoped samples with ${T}_{c} of 60\char21{}70 K, portions of this Fermani surface are not seen.
Abstract: We report angle-resolved photoemission results on ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{Ca}}_{1\ensuremath{-}x}{\mathrm{Dy}}_{x}{\mathrm{Cu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}$ and oxygen depleted ${\mathrm{Bi}}_{2}{\mathrm{Sr}}_{2}{\mathrm{CaCu}}_{2}{\mathrm{O}}_{8+\ensuremath{\delta}}$ investigating the electronic structure changes above ${T}_{c}$ in materials with hole doping levels ranging from insulating to slightly overdoped. Near optimal hole doping, the Fermi surface is large and consistent with band calculations. In underdoped samples with ${T}_{c}$ of 60--70 K, portions of this Fermi surface are not seen. This change is related to the opening of an energy gap near $(\ensuremath{\pi},0)$ above ${T}_{c}$.

TL;DR: In this article, a simple on-column concentration technique in high-performance capillary electrophoresis (HPCE) is reported, where a short plug of water before sample introduction is injected to provide a high electric field strength from the beginning of the injection.

TL;DR: In this article, a method for highly sensitive indirect detection of nuclear magnetic resonance of nuclei having a low gyromagnetic ratio using pulse techniques is presented, which employs a coherent transfer of transverse magnetization from the nuclei of interest to nuclei with high gyromagnetic ratio for which the free induction decay, S (t 2 ), is observed as a function of the length of the time interval, t 1, between imposition of transversal magnetization upon the nucleus of interest and transfer of magnetization to the observed nuclei.
