On the Topological Characterization of Near Force-Free Magnetic Fields, and the work of late-onset visually-impaired Topologists [PDF]

open access: yes, 2015
The Giroux correspondence and the notion of a near force-free magnetic field are used to topologically characterize near force-free magnetic fields which describe a variety of physical processes, including plasma equilibrium.

An elevated bax/bcl-2 ratio corresponds with the onset of prostate epithelial cell apoptosis [PDF]

open access: yesCell Death & Differentiation, 1999
The prostate gland in adult male rats is highly dependent on androgenic steroids. Castration initiates the regression of this tissue through a process involving the loss of the vast majority of cells by means of apoptosis. We studied this well characterized in vivo model of apoptosis to evaluate how the expression of two particular gene products, bcl-2

Negativity Bounds for Weyl-Heisenberg Quasiprobability Representations [PDF]

open access: yes, 2017
The appearance of negative terms in quasiprobability representations of quantum theory is known to be inevitable, and, due to its equivalence with the onset of contextuality, of central interest in quantum computation and information.

Peripheral cuing by abrupt-onset cues: the influence of color in S–R corresponding conditions

open access: yesActa Psychologica, 2004
Research on visuospatial attention indicates that a peripheral abrupt-onset cue at target position (valid condition) facilitates processing of the target, whereas a cue at another position interferes. This validity effect seems to be contingent on a similarity of the cue's color to the set of target colors (cf. J. Exp. Psychol.: Human Percep.

Brane parity orders in the insulating state of Hubbard ladders [PDF]

open access: yes, 2015
The Mott insulating state of the Hubbard model at half-filling could be depicted as a spin liquid of singly occupied sites with holon-doublon quantum fluctuations localized in pairs.

Developmental correspondence between action prediction and motor ability in early infancy. [PDF]

open access: yes, 2011
乳児期初期における他者理解のメカニズムを解明. 京都大学プレスリリース. 2011-06-08How do infants understand the goals of others' actions? It has been proposed that action-understanding results from a mechanism whereby an observed action is mapped onto the observer's own motor ...

Statistical study of the substorm onset: its dependence on solar wind parameters and solar illumination [PDF]

open access: yesAnnales Geophysicae, 2005
Based on 1829 well-defined substorm onsets in the Northern Hemisphere, observed during a 2-year period by the FUV Imager on board the IMAGE spacecraft, a statistical study is performed. From the combination of solar wind parameter observations by ACE and

Impact of rainfall onset date on crops yield in Ghana

open access: yesFrontiers in Sustainable Food Systems, 2023
Rainfall onset date (ROD) influences farmer planting decisions, yet there is a dearth of information on the extent to which ROD influences crop yield. This study assesses the effect of ROD on the yield of four crops (Maize, millet, rice, and sorghum) in ...

Retrospective Analysis of Wood Anatomical Traits Reveals a Recent Extension in Tree Cambial Activity in Two High-Elevation Conifers [PDF]

open access: yes, 2017
The study of xylogenesis or wood formation is a powerful, yet labor intensive monitoring approach to investigate intra-annual tree growth responses to environmental factors.
