Psychological potential field and human eye fixation on binary line-drawing images: A comparative experimental study

引用

Computational Visual Media 2020年第2期6卷 205-214页

作者： Naoyuki Awano yuki Hayashi Osaka University of Economics OsakaOsaka533-8533Japan Osaka Prefecture University SakaiOsaka599-8531Japan

Quantitatively evaluating the psychological and perceptual effects of objects is an important issue,but is difficult. In cognitive studies, the psychological potential field(PPF), which represents psychological intensities in vision and can be calculated by applying computational algorithms to digital images, may help with this issue. Although studies have reported using the PPF to evaluate psychological effects, such as impressions, detailed investigations on how the PPF represents psychological perception and its limitations have not yet been performed. Another relevant tool is the fixation map, which visualizes human eye fixations;this map is generated from actual measurements acquired by eye-tracking and does not represent psychological effects directly. Although the PPF and the fixation map are based on visual imaging, they have never been compared. In this paper, we do so for the first time, using psychological and perceptual properties of line-drawing images. The results demonstrate the difference between these methods, including their representation of different properties with respect to visual perception. Moreover, the similarity between the two methods highlights the possibility of assessing perceptual phenomena such as categorization and cognition of objects based on human vision.

Regulation of Vascular Development by CLE Peptide-receptor Systems

引用

Journal of Integrative Plant Biology 2010年第1期52卷 8-16页

作者： yuki Hirakawa yuki Kondo Hiroo Fukuda Department of Biological Sciences Graduate School of ScienceThe University of Tokyo

Cell division and differentiation of stem cells are controlled by non- cell-autonomous signals in higher organisms. The plant vascular meristem is a stem-cell tissue comprising procambial cells that produce xylem cells on one side and phloem cells on the other side. Recent studies have revealed that TDIF （tracheary element differentiation inhibitory factor）/CLE41/CLE44 peptide signal controls the procambial cell fate in a non-cell-autonomous manner. TDIF produced in and secreted from phloem cells is perceived by TDR/PXY, a leucine-rich repeat receptor kinase located in the plasma membrane of procambial cells. This signal suppresses xylem cell differentiation of procambial cells and promotes their proliferation. In addition to TDIF, some other CLE peptides play roles in vascular development. Here, we summarize recent advances in CLE signaling governing vascular development.

This study aimed to clarify the immediate effect that trunk muscle exercise has on muscle reaction time, and to clarify the effect of 2-week exercise on muscle reaction time. The study showed that as for immediate effects, the muscle reaction time was significantly shortened in the TrA/OI (transversus abdominis muscle/obliquus internus muscle) of two exercise groups. However, the immediate effect seen before the 2-week trunk muscle exercise intervention disappeared after the intervention. In addition, trunk muscle exercise intervention for 2 weeks significantly shortened the muscle reaction time of TrA/OI in one exercise group. Furthermore, shortening of the muscle reaction time was also observed in the MF (multifidus muscle) of both exercise groups. The factors affecting the muscle reaction time of TrA observed in this study were considered to be an improvement of neuromuscular function by the central nervous system. It was also considered that 2-week exercise intervention has a lower value after 2 weeks due to an improvement of neuromuscular function by the central nervous system, and an immediate effect could not be obtained with the same exercise as at the time of intervention.
