An X-ray absorption and photoemission study of the electronic structure of Ni porphyrins and Ni N-confused porphyrin
(2008)Investigations of chemical bonding and electronic structure features for polycrystalline (porphyrinato)nickel (II) (NiP, the simplest Ni porphyrin), (5,10,15,20-tetraphenylporphyrinato)nickel (II) (NiTPP) and (2-aza-2 ... -
X-ray diffraction study of ferroelectric and antiferroelectric liquid crystal mixtures exhibiting de Vries SmA∗-SmC∗ transitions
(2010)In this Rapid Communication, results on smectic layer thickness, using synchrotron radiation x-ray diffraction, for different mixtures of ferroelectric and antiferroelectric liquid crystals are given. We find that with ... -
X-ray laser diffraction for structure determination of the rhodopsin-arrestin complex
(2016)Serial femtosecond X-ray crystallography (SFX) using an X-ray free electron laser (XFEL) is a recent advancement in structural biology for solving crystal structures of challenging membrane proteins, including G-protein ... -
The X-ray spectroscopic diagnosis of laser-produced plasmas, with emphasis on line broadening
(American Physical Society, 1980)A detailed account is given of the x-ray spectroscopic diagnosis of plasmas formed by exploding pusher microballoons. The measurements of the electron temperature from the shell and from the core is described. A method for ... -
X-ray spectroscopic studies of the electronic structure of chromium-based p-type transparent conducting oxides
(2016)The valence band structure of p-type transparent oxides—crystalline MgxCr2−xO3 and nanocrystalline CuxCrOy—is analyzed as a function of incoming photon energy. The valence band of both p-type transparent conducting oxides ... -
X-ray spectroscopic study of the electronic structure of CuCrO2
(2009)The electronic structure of the p-type transparent conducting oxide CuCrO2 has been studied by x-ray photoemission, x-ray absorption, and x-ray emission spectroscopies. The upper part of the valence band derives mainly ... -
X-ray spectroscopic study of the electronic structure of the high-dielectric-constant material CaCu3Ti4O12
(2005)The element-specific valence- and conduction-band densities of states for the high-dielectric-material CaCu 3 Ti 4 O 12 have been measured using soft x-ray emission and absorption spectroscopies. Ti L a , b , ... -
An X11[alpha]/FSBP complex represses transcription of the GSK3[beta] gene promoter.
(2010)X11? is a neuronal adaptor protein that interacts with the amyloid precursor protein (APP) via a centrally located phosphotyrosine binding (PTB) domain to inhibit production of A? peptide that is deposited in Alzheimer's ... -
X11beta rescues memory and long-term potentiation deficits in Alzheimer's disease APPswe Tg2576 mice.
(2009)Increased production and deposition of amyloid ?-protein (A?) are believed to be key pathogenic events in Alzheimer?s disease. As such, routes for lowering cerebral A? levels represent potential therapeutic targets for ... -
X509Cloud - Framework for a Ubiquitous PKI
(2017)The SSL protocol has been widely used for verifying digital identities and to secure Internet traffic since the early days of the web. Although X.509 certificates have been in existence for more than two decades, individual ... -
Xerostomia in patients with advanced cancer: a scoping review of clinical features and complications
(2023)Background: The aim of this project was to review the literature on dry mouth / xerostomia in patients with advanced cancer, with the objectives being to determine its prevalence, clinical features, and complications. Methods: ... -
An XG-PON Module for the NS-3 Network Simulator
(2013)10-Gigabit-capable Passive Optical Network (XG-PON), one of the latest standards of optical access networks, is regar ded as one of the key technologies for future Internet access net - works. In this paper, we propose ... -
