Spectral Hole-Burning Studies of a Mononuclear Eu(III) Complex Reveal Narrow Optical Linewidths of the D→F Transition and Seconds Long Nuclear Spin Lifetimes.

Coordination complexes of rare-earth ions (REI) show optical transitions with narrow linewidths enabling the creation of coherent light-matter interfaces for quantum information processing (QIP) applications. Among the REI-based complexes, Eu(III) complexes showing the D→F transition are of interest for QIP applications due to the narrow linewidths associated with the transition. Herein, we report on the synthesis, structure, and optical properties of a novel Eu(III) complex and its Gd(III) analogue composed of 2,9-bis(pyrazol-1-yl)-1,10-phenanthroline (dpphen) and three nitrate (NO) ligands.

Perceptions of faculty towards online teaching for undergraduate medical education: An interview-based qualitative study.

Background The Covid-19 pandemic drastically affected medical education. One consequence was the shift of teaching-learning process to the online mode. This left many teachers unprepared.

Atlantoaxial Stabilization by Posterior C1 and C2 Screw-Rod Fixation for Various Pathologies: Case Series and Comprehensive Review of Literature.

We retrospectively analyzed atlantoaxial dislocation (AAD) of various pathologies, namely, rheumatoid arthritis (RA), os odontoideum, and trauma. Various techniques were discussed in relation to C1-C2 stabilization. The study aims to share our clinical experience in a series of six cases of C1-C2 instability that underwent posterior C1-C2 fusion, with free hand technique and limited fluoroscopy.

Perceptions of undergraduate medical students regarding institutional online teaching-learning programme.

Background: Medical education all over the country has been forced to shift to e-learning, mainly online classes. In this scenario, the medical education department (MEU) of a teaching hospital under a deemed university felt the need to study the satisfaction and usefulness of these classes, as perceived by the undergraduate medical students.

Methods: Questionnaire survey was planned.

A Rare Case of Giant Intradiploeic Epidermal Cyst of the Frontal Bone with Intracranial Extension.

Calvarial intradiploeic epidermal cyst are very rare neoplasms which can have intracranial extension. These cysts can attain a large size and can cause lytic destruction of the calvarium resembling malignancy. Since these lesions are benign complete excision is curative.
