Time-dependent density functional theory (TDDFT) has broad application in the study of electronic response, excitation and transport. To extend such application to large and complex systems, we develop a reformulation of TDDFT equations in terms of non-orthogonal localized molecular orbitals (NOLMOs). NOLMO is the most localized representation of electronic degrees of freedom and has been used ...

OBJECTIVES Orbital manifestation of Wegener's granulomatosis is diverse and diagnosis is often difficult. This study aims to improve the diagnostic strategy in orbital Wegener. METHODS A review of the diagnostic process in patients in whom a diagnosis of orbital WG was considered. RESULTS Thirty-three patients were analysed, consisting of 15 patients with orbital WG, 11 with idiopathic orbi...

We study the three-orbital Kondo effect in quantum dot (QD) systems by applying the non-crossing approximation to the three-orbital Anderson impurity model. By investigating the tunneling conductance through a QD, we show that the competition between the Hund-coupling and the orbital level-splitting gives rise to characteristic behavior in transport properties. It is found that the Hund-couplin...

Orbital emphysema is typically a benign condition that occurs following forceful injection of air into the orbital soft tissue spaces. In many cases there is a history of trauma and fracture of an orbital bone, which permits air entry. However, other mechanisms of orbital emphysema have been reported including infection, pulmonary barotrauma, injury from compressed-air hoses, and complications ...

BACKGROUND/PURPOSE Orbital fractures are a common facial fracture managed by multiple surgical specialties. Methods: A retrospective review of the electronic medical records of patients (age, 18-85 years) presenting to Northwestern Memorial Hospital and Northwestern Medical Faculty Foundation in Chicago, IL, USA with International Classification of Diseases, Ninth Revision codes for facial frac...

PURPOSE To study the characteristics of orbital cyst associated with microphthalmos in a group of Chinese patients, and to analyze the relationship between orbital cyst and orbital volume. DESIGN Cross-sectional comparative study. PARTICIPANTS 120 patients who were diagnosed as unilateral clinical blind microphthalmos, in which 20 patients had orbital cyst in the affected eye. METHOD Part...
