background: several echocardiographic markers have been introduced to assess the left ventricular (lv) mechanical dyssynchrony. we studied dyssynchrony markers and the latest lv activation site in heart failure patients with and without left bundle branch block (lbbb). methods: conventional echocardiography and tissue velocity imaging were performed for 78 patients (lv ejection fraction ≤ 35%),...

Let G be a complex simply connected semisimple Lie group and let Γ torsionless uniform irreducible lattice in G. Then Γ﹨G is compact non-Kähler manifold whose tangent bundle holomorphically trivial. In this note we compute the Picard of when rank(G)≥3. When rank(G)<3, determine Pic0(Γ﹨G)⊂Pic(Γ﹨G) topologically trivial holomorphic line bundles. rank(G)≥2, also show that Pic0(PΓ) isomorphic to Pi...

Central line-associated bloodstream infections (CLABSI) remained a significant cause of mortality and morbidity in neonatal patients admitted to the neonatal intensive care unit (NICU) who require central line (CL) insertion for whatever medical reason. Recent introduction of CL bundle strategies was associated with a drop in the CLABSI rates. Data about the effect of CL bundle on the rate of C...

Let X a smooth quasi-projective algebraic surface, L a line bundle on X. Let X [n] the Hilbert scheme of n points on X and L the tautological bundle on X [n] naturally associated to the line bundle L on X. We explicitely compute the image Φ(L) of the tautological bundle L for the Bridgeland-King-Reid equivalence Φ : D(X ) → DbSn(X ), in terms of a complex C L of Snequivariant sheaves in DbSn(X ...

We develop a holomorphic equivalence between on one hand the space of pairs (stable bundle, flat connection bundle) and sheaf connections (the splittings one-jet sequence) for determinant (Quillen) line bundle over moduli vector bundles compact connected Riemann surface. This is shown to be holomorphically symplectic. The equivalences, both symplectic, seem quite general, in that they extend ot...

BACKGROUND Consistent radiographic guidelines for tunnel placement in single- or double-bundle posterior cruciate ligament (PCL) reconstructions are not well defined. Quantitative guidelines reporting the location of the individual PCL bundle attachments would aid in intraoperative tunnel placement and postoperative assessment of a PCL reconstruction. HYPOTHESIS Consistent and reproducible me...

This is a topological dynamics perspective on the full bifurcation unfolding in unimodal mappings. We present a bundle structure, visualized as a bundle plot, to show the evolution of symbolic space as we vary a system parameter. The bundle plot can be viewed as a limit process of an assignment plot, which are lines assignments between points from two dynamical systems. Such line assignments ar...

Let G be a simple linear algebraic group defined over the field of complex numbers. Fix a proper parabolic subgroup P of G, and also fix a nontrivial antidominant character χ of P . We prove that a holomorphic principal G–bundle EG over a connected complex projective manifold M is semistable satisfying the condition that the second Chern class c2(ad(EG)) ∈ H (M, Q) vanishes if and only if the l...

The Schrödinger operators on the Newtonian space-time are defined in a way which make them independent on the class of inertial observers. In this picture the Schrödinger operators act not on functions on the space-time but on sections of certain one-dimensional complex vector bundle – the Schrödinger line bundle. This line bundle has trivializations indexed by inertial observers and is associa...

Let M = M̃/Γ be a Kähler manifold, where Γ ' π1(M) and where M̃ is the universal Kähler cover. Let (L, h) → M be a positive Hermitian holomorophic line bundle. We first prove that the L Szegő projector Π̃N for L holomorphic sections on the lifted bundle L̃ → M̃ is related to the Szegő projector for H(M,L ) by Π̂N (x, y) = ∑ γ∈Γ ̃̂ ΠN (γ · x, y). We apply this result to give a simple proof of Napier’s t...
