Soft actuators have a high potential for the creative design of flexible robots and safe human–robot interaction. So far, significant progress has been made in soft actuators’ flexibility, deformation amplitude, variable stiffness. However, there are still deficiencies output force retention. This paper presents new negative pressure-driven folding actuator inspired by origami. First, we establ...

Abstract Biomechanics is a fundamental feature of cell. However, the manner by which actomysin tension affects tumor immune evasion remains unclear. Here we show that although cytotoxic T lymphocytes (CTL) can effectively destroy stiff differentiated cells, they fail to kill soft tumor-repopulating cells (TRC). TRC softness prevented membrane pore formation caused CTL-released perforin. Perfori...

We present an ensemble of classifiers that can be used to predict quality characteristics of an important process in pulp and paper industry: the tissue softness estimation. This classification problem is a difficult one since, with respect to our data set, the accuracy of all the well-known classifiers is below 68%. Contrary to that, the bagging random trees ensemble model is able to increase ...

The projected shell model is used to study the multi-quasiparticle and collective excitations of Hf. With an axially symmetric basis, the spin-16 isomer at 2.4 MeV appears to be well separated in energy/spin space from other configurations. However, projected energy surface calculations suggest that Hf has significant softness to axially asymmetric shapes, which can strongly modify the level di...

Conventional complete denture lacks retention and stability in patients with fibrous hyperplasic tissue. The ideal properties of a denture are adequate rigidity of polished surface to bear masticatory forces and at the same time, flexibility and softness for better stress distribution. In conventional denture, there is uneven distribution of load due to rigidity of tissue surface, especially in...

Although the idea must have been around for years the use of a ball for the calibration of interferometer transmissions spheres was, to our knowledge first reported in 1999. The ball used at the time was made of black (neutral density filter) glass and worked fine for a demonstration of the principle but was not really practical because of its relative softness of the glass and susceptibility t...
