Similarity solutions of Reaction-Diffusion equation with space- and time-dependent diffusion and reaction terms

open access: yes, 2015
We consider solvability of the generalized reaction-diffusion equation with both space- and time-dependent diffusion and reaction terms by means of the similarity method.

Arctic regional methane fluxes by ecotope as derived using eddy covariance from a low-flying aircraft [PDF]

open access: yesAtmospheric Chemistry and Physics, 2017
The Arctic terrestrial and sub-sea permafrost region contains approximately 30 % of the global carbon stock, and therefore understanding Arctic methane emissions and how they might change with a changing climate is important for quantifying the global

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

open access: yesFEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

Diffusion welding [PDF]

open access: yes, 1974
Dispersion-strengthened nickel alloys are sanded on one side and chemically polished. This is followed by a single-step welding process wherein the polished surfaces are forced into intimate contact at 1,400 F for one hour in a vacuum.

Laterality and Sex Differences of Human Lateral Habenula Afferent and Efferent Fiber Tracts

open access: yesFrontiers in Neuroscience, 2022
IntroductionThe lateral habenula (LHb) is an epithalamic nucleus associated with negative valence and affective disorders. It receives input via the stria medullaris (SM) and sends output via the fasciculus retroflexus (FR).
