Geometric Shaping for Distortion-Limited Intensity Modulation/Direct Detection Data Center Links

open access: yesIEEE Photonics Journal, 2023
Intra-data center links are subject to transmission impairments that pose challenges for efficient scaling of per-wavelength data rates beyond 100 Gb/s.

Loop effects in direct detection [PDF]

open access: yesJournal of Cosmology and Astroparticle Physics, 2018
We consider loop level contributions to dark matter scattering off nucleons in cases where the spin independent scattering cross section is absent or suppressed at tree level. In the case of a pseudoscalar interaction, for which the tree level cross section is both spin-dependent and suppressed by 4 powers of the exchanged momentum, we show that loop ...

Challenges in Direct Detection of Flaviviruses: A Review

open access: yesPathogens, 2023
Arthropods transmit arboviruses via mosquito and tick bites to humans and other animals. The genus flavivirus, which causes diseases, sequelae, and thousands of deaths, mainly in developing and underdeveloped countries, is among the arboviruses of ...

Directional Observation of Cold Dark Matter Particles (WIMP) in Light Target Experiments

open access: yesUniverse, 2021
For the last 10 years, the search for dark matter (DM) was carried out taking into account the fact that the DM particles are WIMPs (Weakly Interacted Massive Particles) which were introduced in supersymmetric extensions of the Standard Model.
