• #### X-Box Binding Protein-1 Dependent Plasma Cell Responses Limit the Development of Atherosclerosis. ﻿

(American Heart Association, 2017-07-21)
RATIONALE: Diverse B cell responses and functions may be involved in atherosclerosis. Protective antibody responses, such as those against oxidized lipid epitopes, are thought to mainly derive from T cell-independent innate ...
• #### X-ray generation using carbon nanotubes ﻿

(Springer, 2015-01-06)
Since the discovery of X-rays over a century ago the techniques applied to the engineering of X-ray sources have remained relatively unchanged. From the inception of thermionic electron sources, which, due to simplicity ...
• #### An X-ray magnetic circular dichroism (XMCD) study of Fe ordering in a synthetic MgAl₂O₄ – Fe₃O₄ (spinel – magnetite) solid solution series; implications for magnetic properties. ﻿

(Mineralogical Society of America, 2016-06-02)
Fe L₂,₃-edge XAS and XMCD studies have been used to unravel structural trends in the MgAl₂O₄-Fe₃O₄ solid solution where thermodynamic modelling has presented a challenge due to the complex ordering arrangements of the ...
• #### X-ray properties of cool core galaxy clusters ﻿

(2010-07-06)
• #### X-ray reflectivity method for the characterization of InGaN/GaN quantum well interface ﻿

(Wiley, 2017-08-01)
A method to characterize the interface of InGaN/GaN quantum wells by X-ray reflectivity is presented. The interface roughness can be obtained from the ratio of diffuse to specular scatterings obtained on a transverse ω-scan. ...
• #### X-ray spectroscopy of the $\textit{z}$=6.4 quasar SDSS J1148+5251 ﻿

(Oxford University Press, 2017-06-01)
We present the 78 ks $\textit{Chandra}$ observations of the $\textit{z}$ = 6.4 quasar SDSS J1148+5251. The source is clearly detected in the energy range 0.3–7 keV with 42 counts (with a significance ≳9σ). The X-ray spectrum ...
• #### X-ray structure determination using low-resolution electron microscopy maps for molecular replacement ﻿

(NPG, 2015-07-30)
Structures of multisubunit macromolecular machines are primarily determined either by electron microscopy (EM) or by X-ray crystallography. In many cases, a structure for a complex can be obtained at low resolution (at a ...
• #### The X-ray transform for connections in negative curvature ﻿

(Springer, 2015-11-23)
We consider integral geometry inverse problems for unitary connections and skew-Hermitian Higgs fields on manifolds with negative sectional curvature. The results apply to manifolds in any dimension, with or without boundary, ...
• #### X-rays across the galaxy population – I. Tracing the main sequence of star formation ﻿

(Oxford University Press, 2017-03-01)
We use deep $\textit{Chandra}$ imaging to measure the distribution of X-ray luminosities (LX) for samples of star-forming galaxies as a function of stellar mass and redshift, using a Bayesian method to push below the nominal ...
• #### X-rays from the redshift 7.1 quasar ULAS J1120+0641 ﻿

(Oxford Journals on behalf of the Royal Astronomical Society, 2014-02-27)
We present X-ray imaging and spectroscopy of the redshift z = 7.084 radio-quiet quasar ULAS J112001.48+064124.3 obtained with Chandra and XMM–Newton. The quasar is detected as a point source with both observatories. The ...
• #### Xenophon and the Nazis: a case study in the politicization of Greek thought through educational propaganda ﻿

(Oxford University Press, 2016-01-08)
In National Socialist Germany, radical reinterpretations of Classical texts were always on the agenda. The Reich Education Ministry decreed unequivocally that only those ancient texts which could serve the regime’s new ...
• #### XGAP: a uniform and extensible data model and software platform for genotype and phenotype experiments ﻿

(2010-03-09)
Abstract We present an extensible software model for the genotype and phenotype community, XGAP. Readers can download a standard XGAP (http://www.xgap.org) or auto-generate a custom version using MOLGENIS with programming ...
• #### XIAP and cIAP1 amplifications induce Beclin 1-dependent autophagy through NFκB activation ﻿

(Oxford University Press, 2015-02-10)
Perturbations in autophagy and apoptosis are associated with cancer development. XIAP and cIAP1 are two members of the inhibitors of apoptosis protein family whose expression is elevated in different cancers. Here we report ...
• #### Xist-dependent imprinted X inactivation and the early developmental consequences of its failure ﻿

(Nature Publishing Group, 2017-03-01)
The long noncoding RNA Xist is expressed from only the paternal X chromosome in mouse preimplantation female embryos and mediates transcriptional silencing of that chromosome. In females, absence of Xist leads to ...
• #### The XIV Gyalwa Karmapa--His Divine Personality ﻿

(Namgyal Institute of Tibetology, Gangtok, Sikkim, 1982)
• #### XL-MS: Protein cross-linking coupled with mass spectrometry ﻿

(Elsevier, 2015-06-12)
With the continuing trend to study larger and more complex systems, the application of protein cross-linking coupled with mass spectrometry (XL-MS) provides a varied toolkit perfectly suited to achieve these goals. By ...
