The Review of Economic Studies, 2017 We provide a Keynesian growth theory in which pessimistic expectations can lead to very persistent, or even permanent, slumps characterized by high unemployment and weak growth. We refer to these episodes as stagnation traps, because they consist in the joint occurrence of a liquidity and a growth trap.

Trapping of Neutral Rubidium with a Macroscopic Three-Phase Electric Trap
, 2007 We trap neutral ground-state rubidium atoms in a macroscopic trap based on purely electric fields. For this, three electrostatic field configurations are alternated in a periodic manner.

Efficacy of synthetic lures for pine bark beetle monitoring
Journal of Forest Science, 2022 The Scots pine (Pinus sylvestris) plantations in central Europe are currently damaged by a large-scale infestation by bark beetles (Scolytinae). Ips acuminatus and Ips sexdentatus are among the most aggressive species causing infestations of pine trees ...

Interfacial Insight of Charge Transport in BaTiO3/Epoxy Composites
Nanomaterials, 2023 Space charge accumulation greatly influences the dielectric performance of epoxy composites under high voltage. It has been reported that nano-fillers can suppress the charge accumulation in the bulk of insulation materials.

An improved lure for trapping the bark beetle Dendroctonus armandi (Coleoptera: Scolytinae)
European Journal of Entomology, 2012 The pine bark beetle, Dendroctonus armandi, is a native pest restricted to forests in the Qinling Mountains in China. There was an outbreak of this species there that affected over 0.36 million hectares of pine forest.

Evaporation of buffer gas-thermalized anions out of a multipole rf ion trap
, 2007 We identify plain evaporation of ions as the fundamental loss mechanism out of a multipole ion trap. Using thermalized negative Cl- ions we find that the evaporative loss rate is proportional to a Boltzmann factor.
