While many scholars have noted a rise in boredom coinciding with the emergence of modern capitalism, philosophers have long maintained that boredom is part of the horizon of human experience. Although specific social conditions may exacerbate it, boredom will never be completely eradicated. Nevertheless, its presence indicates that something is not right.

Studies of laser-driven strong field processes subjected to a (quasi-)static field have been mainly confined to theory. Here we provide an experimental realization by introducing a bichromatic approach for high harmonic generation (HHG) in a dielectric that combines an intense 70 femtosecond duration mid-infrared driving field with a weak 2 picosecond period terahertz (THz) dressing field. We address the physics underlying the THz field induced static symmetry breaking and its consequences on the efficient production/suppression of even-/odd-order harmonics, and demonstrate the ability to probe the HHG dynamics via the modulation of the harmonic distribution.

We report on a tunable intense femtosecond mid-infrared (mid-IR) light source carrying orbital angular momentum (OAM). Our setup is based on an optical parametric amplification system with an 800 nm pump shaped with a spiral phase plate. We confirm the anisotropic OAM transfer from the pump to the idler through stimulated difference frequency generation by measuring the diffraction patterns of a triangular aperture illuminated by the signal, pump, and idler beams.

Background: Tobacco abuse is a well-recognized scourge on health and healthcare costs. Attempts to facilitate tobacco cessation are rarely better than marginally effective.

Primary Objective: To describe an observational trial of an existing and highly successful tobacco cessation program featuring health coaching as the primary intervention.

The purpose of this research was to determine what impact the Indiana 4-H Tractor Program has had on safer tractor operating behavior and attitudes of participants and to provide recommendations for program improvement. To assess the impact, 108 non 4-H youth who reported they operated a tractor regularly were compared with 104 4-H Tractor Program participants. A single skilled evaluator observed each individual in the two groups as she/he operated a tractor through a standard tractor-operating course.
