ECOS: Evolutionary Column-Oriented Storage [PDF]

open access: yes, 2011
As DBMS has grown more powerful over the last decades, they have also become more complex to manage. To achieve efficiency by DBMS tuning is nowadays a hard task carried out by experts. This development inspired the ongoing research on self-tuning to make DBMS more easily manageable.

Enhancement of Planar Orientation of Reactive Mesogen Molecules for Optical Retarder Film by Anisotropic Surface Plasma Treatment

open access: yesCrystals, 2021
We proposed a method for enhancing the planar orientation of reactive mesogen (RM) molecules by means of anisotropic plasma treatment. Anisotropic surface plasma, of which energy density is dependent on the azimuthal angle, was generated by column-shaped

Visual Background Choice and Light Environment Affect Male Guppy Visual Contrast

open access: yesVision, 2022
Male guppies (Poecilia reticulata) have multiple colored spots and perform courtship displays near the edges of streams in Trinidad in shallow water flowing through rainforest. Depending upon the orientation of the pair, the female sees the male displays

Orientation columns in the mouse superior colliculus

open access: yesNature, 2014
More than twenty types of retinal ganglion cells conduct visual information from the eye to the rest of the brain. Each retinal ganglion cell type tessellates the retina in a regular mosaic, so that every point in visual space is processed for visual primitives such as contrast and motion.

The pairwise phase consistency in cortical network and its relationship with neuronal activation

open access: yesBIO Web of Conferences, 2017
Gamma-band neuronal oscillation and synchronization with the range of 30-90 Hz are ubiquitous phenomenon across numerous brain areas and various species, and correlated with plenty of cognitive functions.

Thermal Stability of PS-PVD YSZ Coatings with Typical Dense Layered and Columnar Structures

open access: yesCrystals, 2020
Yttria-stabilized zirconia (YSZ) coatings with typical pyramid columnar and dense layered structure were prepared by plasma spray-physical vapor deposition (PS-PVD).

Contributions of cell behavior to geometric order in embryonic cartilage.

open access: yesPLoS Computational Biology, 2023
During early development, cartilage provides shape and stability to the embryo while serving as a precursor for the skeleton. Correct formation of embryonic cartilage is hence essential for healthy development.

xial compression behaviour of hybrid composite FRP–concrete–steel double-skin tubular columns with various fibre orientations

open access: yesCase Studies in Construction Materials, 2022
The hybrid double-skin tubular column (DSTC) is a unique composite column composed of an outer tube made of a fibre-reinforced polymer (FRP) and an inner tube made of steel, with concrete filling the space between the outer and inner tubes.

What are we learning from the relative orientation between density structures and the magnetic field in molecular clouds [PDF]

open access: yes, 2017
We investigate the conditions of ideal magnetohydrodynamic (MHD) turbulence responsible for the relative orientation between density structures, characterized by their gradient, $\vec{\nabla}\rho$, and the magnetic field, $\vec{B}$, in molecular clouds ...
