1 Introduction Deterministic single-photon emitters, which release one photon at a time, are fundamental to quantum information science applications such as quantum computing[1-4] and communication.[5-8] Researchers have been actively working on developing efficient single-photon emitters based on two primary platforms: semiconductor quantum dots (QDs)[1-11] and defect-based solid-state materials, including diamond, SiC, transition-metal dichalcogenide, h-BN and GaN.[12-18] Each platform...

1. Introduction Proper posture refers to a state of musculoskeletal balance that imposes a minimum amount of stress and strain on body structures [1]. Many people suffer from poor posture, and postural abnormalities can have a negative impact on musculoskeletal balance and psychological health [2]. A poor or altered posture of the spine can put considerable pressure on the surrounding muscles and ligaments, which can eventually affect the stability of the spine.
