Boron (B) is required for cross linking of the pectic polysaccharide rhamnogalacturonan II (RG-II) and consequently essential maintenance cell wall structure. Arabidopsis (Arabidopsis thaliana) BOR1 an efflux B transporter xylem loading B. Here, we describe roles BOR2, most similar paralog BOR1. BOR2 encodes localized in plasma membrane strongly expressed lateral root caps epidermis elongation zones roots. Transfer DNA insertion reduced by 68%, whereas mutation it 32% under low availability...

We have measured the visual similarity between photos manually by making dozens of people classify similar photos. proposed method how to predict unmeasured use several 1000 class classifications pre-trained Convolutional Neural Networks (CNNs). conducted a survey asking students take their lives that interest them. 200 were collected from 2012 2014. The matrix P these was measured. Q them easily obtained CNNs. Divide into two groups A and B. Assuming only included in Minimizing Kullback -...

By using the objective visual similarity matrix P that is given only to some photo pairs and image Q can be calculated automatically for all pairs, of missing parts predicted. To make we use 1000 class classification semantic segmentation photos by pre-trained Convolutional Neural Networks (CNNs). Minimizing Kullback-Leibler divergence between two Gaussian distributions with mean 0, covariance respectively, completed. 200 were collected from students at University Tokyo was measured. 184...

There were three types of photo sets, 200 student life photos, 242 townscapes, and 100 garden landscapes. The photos included various including landscapes, objects, people, food. On the other hand, there only in was some variation townscapes. inter-photo visual similarity had been measured manually for each set. Dividing set randomly into training test data parts, predicted via pre-trained computer vision models (CVMs), such as CNN, Vision Transformer (ViT), CLIP. prediction accuracy could...

SALoT Map is the impression map of a town that integrates collective information snapshots (S), attributes (A) person who took snapshots, their locations (Lo) and descriptive texts (T). It constructed by two-stage procedure: classification locations, correspondence analysis on words in texts. Using intelligence, method can translate subjective individual impressions into rather an objective comprehensive expression. One hundred twenty-eight local college students part survey to search...

'Collective intelligence' is defined as groups of individuals doing things collectively that seem intelligent. Currently, many students have digital cameras or cell-phone cameras. Moreover, a good network environment commonly available and it has become very easy to collect email photos. We aimed analyze landscape cognition using 'collective large number photos taken target place by students. A web-based system was developed aggregate the collected On this web system, each student used...

In order to obtain some informations on the behavior or translocation and storage of nitrogen compounds in root tubers during growing period, present investigation was undertaken with sweet potatoes variety "Gokoku" as material. The experimental results obtained may be summarized follows : 1. At early stage tuber growth, protein-N contents were relatively high prominent soluble-N also recognized, but they display a tendency decrease concomitant march their development. 2. accordance vigorous...

The viewpoints to private gardens in Japan were compared between Japanese and British students. Sample of garden landscapes was collected through area sampling. From the rate familiarity students landscapes, divided into ‘unfamiliar’ and‘familiar’ gardens. Comparison made by correspondence analysis data gathered psychological experiments using questionnaires. When two groups' characters are analysis, meaning components revealed differs groups. To see this detail, British's with highest...

The development of deep learning for image cognition is remarkable. Computer Vision Models (CVMs) such as CNN, Transformer (ViT), and CLIP, which were pretrained on a huge amount training data, released. We studied environmental using photos. Photos quantified by many participants manually measuring the inter-phot visual similarity (IVS). had three types photosets:, 200 student life photos, 242 townscapes, 100 garden landscapes. measured how similar inter-photo CVM with IVS MDS coordinates....

Individual differences in the ways to perceive residential garden-views were investigated. Japanese and English participants required choose domestic gardens (existing their own country) from a garden-view picture set presented.
