Adaptive Filtering for Multi-Track Audio Based on Time–Frequency-Based Masking Detection (2024)
Journal Article
Zhao, W., & Pérez-Cota, F. (2024). Adaptive Filtering for Multi-Track Audio Based on Time–Frequency-Based Masking Detection. Signals, 5(4), 633-641. https://doi.org/10.3390/signals5040035

There is a growing need to facilitate the production of recorded music as independent musicians are now key in preserving the broader cultural roles of music. A critical component of the production of music is multitrack mixing, a time-consuming task...

Super-resolution imaging using nano-bells (2018)
Journal Article
Fuentes-Dominguez, R., Pérez-Cota, F., Naznin, S., Smith, R. J., & Clark, M. (2018). Super-resolution imaging using nano-bells. Scientific Reports, 8, 1-9. https://doi.org/10.1038/s41598-018-34744-6

In this paper we demonstrate a new scheme for optical super-resolution, inspired, in-part, by PALM and STORM. In this scheme each object in the field of view is tagged with a signal that allows them to be detected separately. By doing this we can ide...

Cell imaging by phonon microscopy: sub-optical wavelength ultrasound for non-invasive imaging (2017)
Journal Article
Perez-Cota, F., Smith, R. J., Moradi, E., Leija, A. L., Velickovic, K., Marques, L., Webb, K. F., Symonds, M. E., Sottile, V., Elsheikha, H., & Clark, M. (2017). Cell imaging by phonon microscopy: sub-optical wavelength ultrasound for non-invasive imaging

The mechanical properties of cells play an important role in cell function and behavior. This paper presents recent developments that have enabled the use of laser-generated phonons (ultrasound) with sub-optical wavelengths to look inside living cell...

High resolution 3D imaging of living cells with sub-optical wavelength phonons (2016)
Journal Article
Perez-Cota, F., Smith, R. J., Moradi, E., Marques, L., Webb, K. F., & Clark, M. (2016). High resolution 3D imaging of living cells with sub-optical wavelength phonons. Scientific Reports, 6, Article 39326. https://doi.org/10.1038/srep39326

Label-free imaging of living cells below the optical diffraction limit poses great challenges for optical microscopy. Biologically relevant structural information remains below the Rayleigh limit and beyond the reach of conventional microscopes. Supe...

Optically excited nanoscale ultrasonic transducers (2015)
Journal Article
Smith, R. J., Cota, F. P., Marques, L., Chen, X., Arca, A., Webb, K., Aylott, J. W., Somekh, M. G., & Clark, M. (2015). Optically excited nanoscale ultrasonic transducers. Journal of the Acoustical Society of America, 137(1), 219-227. https://doi.org/10.1121/1.4904487

© 2015 Acoustical Society of America. In order to work at higher ultrasonic frequencies, for instance, to increase the resolution, it is necessary to fabricate smaller and higher frequency transducers. This paper presents an ultrasonic transducer cap... Read More about Optically excited nanoscale ultrasonic transducers.
