Bando-futaki Invariants on Hypersurfaces
In 1983, Futaki introduced the well-known Futaki invariant [6], which is an obstacle to the existence of Kähler-Einstein metrics on a compact complex manifold with positive first Chern class. Other generalizations of the Futaki invariant were introduced later, all of which are obstructions to certain geometric structures. The Calabi-Futaki invariant [3] is an obstruction to the existence of Käh...
متن کاملOn the Futaki Invariants of Complete Intersections
In 1983, Futaki [2] introduced his invariants which generalize the obstruction of Kazdan-Warner to prescribe Gauss curvature on S. The Futaki invariants are defined for any compact Kähler manifold with positive first Chern class that has nontrivial holomorphic vector fields. Their vanishing are necessary conditions to the existence of Kähler-Einstein metric on the underlying manifold. Let M be ...
متن کاملSpontaneous Breathing Trial a Reliable Method for Weaning in Children
Introduction Mechanical ventilation may be lifesaving intervention,It can be associated with complications,Thus,successful weaning is constitutive.One of the factors which is important in successful weaning is method of weaning. It is shown that weaning is conducted successfully by using Spontaneous Breathing Trial (SBT) through T-piece and pressure support (PS) ventilation.But few studies ...
متن کاملThe Effect of Motivational Abdominal Breathing Device on Breathing Patterns and Shortness of Breath in Patients with Chronic Obstructive Pulmonary Disease
Background and purpose: Despite the high prevalence of chronic obstructive pulmonary disease, There haven,t been definite curative treatment for the disease and focus of treatment has directed towards pulmonary rehabilitation as an effective non-drug treatments. this study were performed to determine the effect of motivational abdominal breathing device on breathing pattern and dyspnea of chron...
متن کاملRegistration of Free-Breathing Abdominal 3D Contrast-Enhanced CT
CT perfusion imaging is used for the follow-up of abdominal tumors. A specificity of our work is that patients are breathing freely during image acquisition (5 minutes). We propose an automatic 3D image registration to compensate respiratory motion. The registration is computed in two main steps: global translation in the z-direction and 3D multiresolution blockmatching. Within this algorithm, ...
