Efficient optomechanical refrigeration of two vibrations via an auxiliary feedback loop: Giant enhancement in mechanical susceptibilities and net cooling rates

open access: yesPhysical Review Research, 2022
We propose a method to realize the simultaneous ground-state refrigeration of two vibrational modes beyond the resolved-sideband regime via an auxiliary feedback loop (AFL).

Evolution from Periodic Intensity Modulations to Dissipative Vector Solitons in A Single-Mode Fiber Laser

open access: yesPhotonics, 2020
We investigated—both experimentally and numerically—the operation of a weakly birefringent cavity fiber laser under different net cavity dispersion values.

Differences in viral decay and production following exposure to sunlight and dark

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2023
Although we have gained insight into the biological and biochemical effects of natural sunlight exposure on prokaryotes, little is known about sunlight exposure on natural virus communities.

Can a galaxy redshift survey measure dark energy clustering? [PDF]

open access: yes, 2006
(abridged) A wide-field galaxy redshift survey allows one to probe galaxy clustering at largest spatial scales, which carries an invaluable information on horizon-scale physics complementarily to the cosmic microwave background (CMB).

Microbenthic Net Metabolism Along Intertidal Gradients (Cadiz Bay, SW Spain): Spatio-Temporal Patterns and Environmental Factors [PDF]

open access: yes, 2020
Microphytobenthos (MPB), the photosynthetic primary producing component of microbenthos, shows variable patterns in its biomass distribution along the intertidal gradient as a result of the interactions of factors such as light, tides, temperature ...

Bright–Dark Pulse Pair in a Figure-Eight Dispersion-Managed Passively Mode-Locked Fiber Laser

open access: yesIEEE Photonics Journal, 2012
We report on the generation of bright–dark pulse pair in a figure-eight dispersion-managed (DM) passively mode-locked fiber laser with net anomalous cavity group velocity dispersion (GVD). The nonlinear amplifying loop mirror (NALM) is employed in

On the Prospects for Detecting a Net Photon Circular Polarization Produced by Decaying Dark Matter

open access: yes, 2017
If dark matter interactions with Standard Model particles are $CP$-violating, then dark matter annihilation/decay can produce photons with a net circular polarization.

Photosynthetic responses of three common mosses from continental Antarctica [PDF]

open access: yes, 2005
Predicting the effects of climate change on Antarctic terrestrial vegetation requires a better knowledge of the ecophysiology of common moss species. In this paper we provide a comprehensive matrix for photosynthesis and major environmental parameters ...
