Prior research showed that observers can tolerate large speed alterations in real-world videos. The present study examined how sensitive the human visual system is to the change of kinematic information of human actions with altered playback speeds. We recorded four persons walking at various speeds and produced point-light walker stimuli (standard stimuli), from which we also created test stimuli either by speeding up or slowing down the playback speed. In the experiments, two point-light walkers were presented sequentially: one standard and the other test stimuli. Importantly, in each trial, the expected speed of translation was kept constant (e.g., a pair of one walking at 5.40 km/h and the other walking at 2.70 km/h but played with double speed), differing only in gait kinematic information. Participants reported which stimulus was played at a normal speed. We also included the manipulations of orientation (upright vs. inverted) and spatial scrambling of the point-light dots. The results showed that the unnaturalness detection was performed at above chance levels, confirming that kinematic inconsistencies provided a discernible cue. However, detection was only reliable when the speed alteration in a test stimulus was fairly large. Interestingly, we found little differences in performance among upright-intact, inverted, and scrambled conditions. The lack of the large detriments from inversion or scrambling suggests that the participants did not rely strongly on global form or orientation cues to perform the unnaturalness detection and points to greater contributions of local motion signals.

When railway vehicles running in snowy weather, the adhesive force between rails and wheels is lower than that in rainy weather. For this reason, we studied a method to increase the adhesion coefficient focusing on the temperature and the roughness of wheel treads. From the viewpoint of minimizing specification changes, improving the material of current abrasive block through full-scale dynamo bench test, we developed new abrasive block. An optimal wheel tread cleaner device operating pattern was found through running tests using an actual vehicle in winter. The execution of the pattern contributes to improving adhesive effect such as increasing roughness of wheel treads, and suppressing slipping in the high-speed range, in addition to reducing temperature rise and improving wear resistance.

A new family of Mg salts of carba-closo-dodecaborate was developed for Mg ion battery applications. Modification at the boron vertices drastically improves the solubility without compromising the chemical and redox stability.

The objective of our studies is the inquiry into data set of the silhouette styling by machine learning for the luxury brands. The computer vision meets the visual fashion for the long years. Recently, computer vision techniques has been employed in algorithm of fashion recognition. But the aim of the computer vision is that the computer vision meets fashion but not that fashion meets computer visions. The luxury fashion consumer expects the favorite own beautiful silhouette styling, not simply the computer pictures. Therefore, silhouette learning of clothing by Neural Network Console needs to meet the personal professional styling knowledge.

Our attempts to deprotometalate N,N-dialkyl ferrocenecarboxamides enantioselectively by using chiral lithium or lithium–zinc dialkylamides are reported.

The dynamics of colloidal gel particle suspensions, i.e., microgel suspensions, has been investigated by dynamic light scattering (DLS) over a wide concentration range from the (I) dilute (φ < φcp) to the (II) intermediate (φ ≈ φcp) and (III) high concentration regions (φ ≫ φcp), where φ and φcp are the volume fraction of the gel particles in the suspension and the random close packing fraction, φcp ≈ 0.64, respectively. The time-intensity correlation function exhibited a distinct change with increasing φ, i.e., from ergodic behaviour (region I and II) to nonergodic behaviour (region III). A mode transition from translational (region I) to cooperative diffusion (the so-called gel mode) (region II) was also observed due to the soft and deformable nature of the microgels. Different from the dynamics of hard colloidal glass suspensions, the gel mode remained even at φ ≫ φcp. By using the ensemble-averaged time-correlation function, IE, we quantify the relationship between φ and their dynamics, and show that the soft microgels are deswollen in the densely packed state.
