A Theory of How Columns in the Neocortex Enable Learning the Structure of the World

open access: yesFront. Neural Circuits, 2017
Neocortical regions are organized into columns and layers. Connections between layers run mostly perpendicular to the surface suggesting a columnar functional organization.

A parametric study on buckling of R/C columns exposed to fire [PDF]

open access: yes, 2016
Buckling of concrete columns is a major issue in fire design, since heating of the columns will result in loss of stiffness and strength in the outer concrete layers.

Three years of greenhouse gas column-averaged dry air mole fractions retrieved from satellite – Part 2: Methane [PDF]

open access: yes, 2008
Carbon dioxide (CO2) and methane (CH4) are the two most important anthropogenic greenhouse gases. SCIAMACHY on ENVISAT is the first satellite instrument whose measurements are sensitive to concentration changes of the two gases at all altitude levels ...

Growth of single-crystal columns of CoSi2 embedded in epitaxial Si on Si(111) by molecular beam epitaxy [PDF]

open access: yes, 1989
The codeposition of Si and Co on a heated Si(111) substrate is found to result in epitaxial columns of CoSi2 if the Si:Co ratio is greater than approximately 3:1. These columns are surrounded by a Si matrix which shows bulk-like crystalline quality based

Modeling Stone Columns

open access: yesMaterials, 2017
This paper reviews the main modeling techniques for stone columns, both ordinary stone columns and geosynthetic-encased stone columns. The paper tries to encompass the more recent advances and recommendations in the topic. Regarding the geometrical model,

Comparison of impulsive wave forces on a semi-submerged platform deck, with and without columns and considering air compressibility effects, under regular wave actions

open access: yesEngineering Applications of Computational Fluid Mechanics, 2021
The decks of oil-extracting  platforms could be damaged by great wave impact loads under harsh ocean conditions. Our understanding of the pressure distribution characteristics under the deck, especially those influenced by columns, is incomplete.

Analytical modeling of reinforced concrete columns subjected to bidirectional shear [PDF]

open access: yes, 2017
Under general seismic loading, reinforced concrete columns may be subjected to lateral loads in more than one direction. Available experimental data on columns subjected to bidirectional forces indicate that higher levels of damage and a higher loss of ...
