AdS/QCD and light front holography: A new approximation to QCD

Light-front holography leads to a rigorous connection between hadronic amplitudes in a higher dimensional anti-de Sitter(AdS) space and frame-independent light-front wavefunctions of hadrons in(3 + 1)-dimensional physical space-time,thus providing a compelling physical interpretation of the AdS/CFT correspondence principle and AdS/QCD,a useful framework which describes the correspondence between theories in a modified AdS 5 background and confining field theories in physical *** a first semiclassical approximation,where quantum loops and quark masses are not included,this approach leads to a single-variable light-front Schro¨dinger equation which determines the eigenspectrum and the light-front wavefunctions of hadrons for general spin and orbital angular *** coordinate z in AdS space is uniquely identified with a Lorentz-invariant coordinate ζ which measures the separation of the constituents within a hadron at equal light-front *** internal structure of hadrons is explicitly introduced and the angular momentum of the constituents plays a key *** give an overview of the light-front holographic approach to strongly coupled *** particular,we study the photon-to-meson transition form factors(TFFs) FMγ(Q 2) for γ→ M using light-front holographic *** results for the TFFs for the η and η ' mesons are also *** novel features of QCD are discussed,including the consequences of confinement for quark and gluon condensates.A method for computing the hadronization of quark and gluon jets at the amplitude level is outlined.

自汶川大地震以来,"爱"似乎成了城中热话,人们亦开始思考关爱、和谐与人性的美好给人类社会带来的震撼、感动和改变。痛定思痛,历史总能留给我们一些教训。而本文作者通过简单的故事,以一种平淡而深沉的方式,从某种程度上暴露和讽刺了在当时那麻木自私的思想腐蚀下,人们精神的堕落。希望在未来,主人公的遭遇真真正正地成为历史……

Simultaneous Endovascular Approach for Aortic Arch Aneurysm Associated with Aortic Valve Stenosis. What Have We Learned?

引用

International Journal of Clinical Medicine 2015年第2期6卷 81-84页

作者： Joel Lapeze guy Durand de Gevigney Didier Revel Olivier Jegaden department of Cardiovascular Surgery Louis Pradel HospitalLyonFrance department of Cardiology Louis Pradel HospitalLyonFrance department of Radiology Louis Pradel HospitalLyonFrance department of Cardiovascular Surgery Cleveland Clinic Abu DhabiAbu DhabiUAE

Aortic arch aneurysms are rarely isolated entities, and most frequently associated with either ascending or descending aorta pathologies. Association with aortic valve stenosis is uncommon and traditional surgical treatment is always challenging. Here we report a minimally invasive and endovascular management of these two pathologies in a 89-year-old man with LAD-stented ischemic cardiomyopathy. We describe our initial therapeutic strategy, per procedure difficulties and final management of this challenging case. Finally, we discuss the different therapeutic options for the endovascular treatment of aortic arch aneurysm associated with aortic valve stenosis.
