Lattice fence and hedge barriers around an apiary increase honey bee flight height and decrease stings to people nearby [PDF]
, 2014 Urban beekeeping is becoming more popular in the UK. One of the challenges faced by urban beekeepers is finding a suitable apiary location. Honey bees are often perceived as a nuisance, mainly due to their stinging behaviour. Here, we experimentally test

Duck! Scaling the height of a horizontal barrier to body height [PDF]
Attention, Perception & Psychophysics, 2010 Recent research shows that the body is used to scale environmental extents. We question whether the body is used to scale heights as measured by real actions (Experiments 1 and 2) or by judgments about action and extent made from a single viewpoint (Experiments 3 and 4).

Apparent Barrier Height in Scanning Tunneling Microscopy Revisited [PDF]
Physical Review Letters, 1996 The apparent barrier height ${\ensuremath{\varphi}}_{\mathrm{ap}}$, that is, the rate of change of the logarithm of the conductance with tip-sample separation in a scanning tunneling microscope (STM), has been measured for Ni, Pt, and Au single crystal surfaces.

Barrier height inhomogeneities on Pd/n-4H-SiC Schottky diodes in a wide temperature range
Materials Science and Engineering: B, 2019 Barrier height inhomogeneities on Pd/n-type 4H-SiC Schottky barrier diodes in the 300–800 K temperature range have been investigated. Palladium is known to form silicide above 673 K.

Electric field modulation of Schottky barrier height in graphene/MoSe2 van der Waals heterointerface [PDF]
, 2015 We demonstrate a vertical field-effect transistor based on a graphene/MoSe2 van der Waals (vdW) heterostructure. The vdW interface between the graphene and MoSe2 exhibits a Schottky barrier with an ideality factor of around 1.3, suggesting a high-quality

Electrical and Photovoltaic Properties of In-pSi Contact [PDF]
Engineering and Technology Journal, 2007 In the present work, the electrical and photovoltaic properties of In-pSi contact were investigated for the first time. Two creditable methods were used to determine the value of barrier height for this contact.

Direct Measurement of Barrier Heights in Protein Folding [PDF]
Journal of the American Chemical Society, 2005 A serious limitation in the study of protein folding reactions resides in the lack of experimental methods to measure the absolute height of the free energy barrier. This is particularly unfortunate given that if folding barriers are small, as theory predicts, it might be possible to resolve folding mechanisms directly.
