We demonstrate a (FMCW) light detection and ranging (LIDAR) system utilizing a (SNSPD) to measure vibrational spectra using reflected signals at the single-photon level. By determining the time-variant Doppler shift of the reflected probe signal, this system successfully reconstructs various audio signals, including pure sinusoidal, multi-tonal, and musical signals, up to 200 Hz, limited by the laser frequency modulation rate and the Nyquist sampling theorem. Additionally, we employ scanning galvo mirrors to perform 3D measurements and map audio signals from different regions in the scanned field of view.

This study delves into how various musical factors influence the experience of auditory illusions, building on Diana Deutsch's scale illusion experiments and subsequent studies. Exploring the interaction between scale mode and timbre, this study assesses their influence on auditory misperceptions, while also considering the impact of an individual's musical training and ability to discern absolute pitch. Participants were divided into nonmusicians, musicians with absolute pitch, and musicians with relative pitch, and were exposed to stimuli modified across three scale modes (tonal, dissonant, atonal) and two timbres (same, different).

Context: Several data from the literature have focused on the relationship between congenital sensorineural hearing loss, as well as acquired hearing loss, and their impact on cognition and the risk of dementia. However, few studies have been conducted on this subject in countries where access to hearing rehabilitation measures is limited. Thus, the objective of the present study was to investigate the relationship between sensorineural hearing loss and cognitive disorders in a correlational approach.

In Western tonal music, major and minor modes are recognized as the primary musical features in eliciting emotional responses. The underlying correlates of this dichotomy in music perception have been extensively investigated through decades of psychological and neuroscientific research, yielding plentiful yet often discordant results that highlight the complexity and individual differences in how these modes are perceived. This variability suggests that a deeper understanding of major-minor mode perception in music is still needed.

Background: Modified Cajal's trichrome stain (MCTS) is a good differential stain that allows one to visibly distinguish between connective tissue and epithelial elements with different tonalities of colour.
Aim: Our study aims to evaluate and analyse the effectiveness of oral squamous cell carcinoma (OSCC) using MCTS.
Materials And Methods: A study was conducted retrospectively with 30 tissue blocks embedded in paraffin from cases of OSCC that have been confirmed by histopathology.
