Science with a Small Two-Band UV-Photometry Mission III: Active Galactic Nuclei and Nuclear Transients by Zajaček, M., Czerny, B., Jaiswal, V. K., Štolc, M., Karas, V., Pandey, A., Pasham, D. R., Śniegowska, M., Witzany, V., Suková, P., Münz, F., Werner, N., Řípa, J., Merc, J., Labaj, M., Kurfürst, P., Krtička, J.

“…For tidal disruption events (TDEs), high-cadence UV monitoring is crucial for distinguishing among different scenarios for the origin of the UV emission. The small two-band UV space telescope will also provide information about the near- and far-UV continuum variability for rare transients, such as repetitive partial TDEs and jetted TDEs. …”

Investigating the EM performance of building materials for mid-band 5G in urban built environment: an exploratory study by Ng, Sean Jake Peng

“…The resulting polynomial model delineates the change in frequency response to a corresponding change in continuous factor levels within the parameter space of the experimental design. The thesis is concluded with the investigation of material loading on an evolved antecedent hexagonal-stubbed complementary split-ring resonator (CSRR)-loaded electrically small antenna (ESA) designed to cover the 3.5 GHz 5G frequency band. …”
