Scientific Reports, 2021 AbstractIt has been experimentally reported that chemotactic cells exhibit cellular memory, that is, a tendency to maintain the migration direction despite changes in the chemoattractant gradient. In this study, we analyzed a phenomenological model assuming the presence of cellular inertia, as well as a response time in motility, resulting in the ...

Nature, 1889 As a student and teacher of physics who has come much into contact with engineers and other artisans, I venture to say a few words on the vexed question of dynamical units now under discussion in your pages. It seems to me that it would be a distinctly retrograde step to adopt the proposals which Mr. Worthington makes in a recent number of NATURE.

On the carrier of inertia [PDF]
AIP Advances, 2018 A change in momentum will inevitably perturb the all-embracing vacuum, whose reaction we understand as inertia. Since the vacuum’s physical properties relate to light, we propose that the vacuum embodies photons, but in pairs without net electromagnetic fields.

Multivariate Autoregressive Model Based Heart Motion Prediction Approach for Beating Heart Surgery
International Journal of Advanced Robotic Systems, 2013 A robotic tool can enable a surgeon to conduct off-pump coronary artery graft bypass surgery on a beating heart. The robotic tool actively alleviates the relative motion between the point of interest (POI) on the heart surface and the surgical tool and ...
