Habitat requirements of black mudfish (Neochanna diversus) in the Waikato region, North Island, New Zealand. [PDF]
, 1996 Black mudfish (Neochanna diversus) were found at 39 of 80 sites in the Waikato region, New Zealand, ranging from large wetlands to small swampy streams. Of the sites with mudfish, 87% were dry at some time during summer. Sites with mudfish also generally

Glutamate-mediated blood-brain barrier opening. implications for neuroprotection and drug delivery [PDF]
, 2016 The blood-brain barrier is a highly selective anatomical and functional interface allowing a unique environment for neuro-glia networks. Blood-brain barrier dysfunction is common in most brain disorders and is associated with disease course and delayed ...

Fusion at deep subbarrier energies: potential inversion revisited [PDF]
, 2008 For a single potential barrier, the barrier penetrability can be inverted based on the WKB approximation to yield the barrier thickness. We apply this method to heavy-ion fusion reactions at energies well below the Coulomb barrier and directly determine ...

Large-angle scattering and quasi-elastic barrier distributions [PDF]
, 2004 We study in detail the barrier distributions extracted from large-angle quasi-elastic scattering of heavy ions at energies near the Coulomb barrier. Using a closed-form expression for scattering from a single barrier, we compare the quasi-elastic barrier

Akt-dependent Pp2a activity is required for epidermal barrier formation during late embryonic development [PDF]
, 2009 Acquisition of epidermal barrier function occurs late in mouse gestation. Several days before birth a wave of barrier acquisition sweeps across murine fetal skin, converging on dorsal and ventral midlines.

Cold Spring Harbor Perspectives in Medicine, 2014 The epidermis functions as a physical barrier to the external environment and works to prevent loss of water from the skin. Numerous factors have been implicated in the formation of epidermal barriers, such as cornified envelopes, corneocytes, lipids, junctional proteins, proteases, protease inhibitors, antimicrobial peptides, and transcription factors.

The conditional tunneling time for reflection using the WKB wave-function [PDF]
, 2002 We derive an expression for the conditional time for the reflection of a wave from an arbitrary potential barrier using the WKB wavefunction in the barrier region.

Natural Barriers and Policy Barriers [PDF]
SSRN Electronic Journal, 2020 This paper investigates whether "natural" trade barriers of a country due to geography and other factors outside the country's control stimulate more or less policy barriers such as tariffs. Our theory predicts that the politician's relative weight on private benefits over social welfare in a "protection-for-sale" setup depends on these "natural ...

Characterizations of safety in hybrid inclusions via barrier functions [PDF]
, 2019 This paper investigates characterizations of safety in terms of barrier functions for hybrid systems modeled by hybrid inclusions. After introducing an adequate definition of safety for hybrid inclusions, sufficient conditions using continuously ...

Performance of T-shape barriers with top surface covered with absorptive quadratic residue diffusers [PDF]
, 2008 A previous paper [Applied Acoustics 66 (2005) 709–730] has shown that adding a quadratic residue diffuser (QRD) to the top of a T-shape barrier can provide better barrier performance than an equivalent purely absorptive barrier.
