Slowly-compressed single crystals, bulk metallic glasses (BMGs), rocks, granular materials, and the earth all deform via intermittent slips or "quakes". We find that although these systems span 12 decades in length scale, they all show the same scaling behavior for their slip size distributions and other statistical properties. Remarkably, the size distributions follow the same power law multip...
Spondylolysis is the term used for a defect in the pars interarticularis of the vertebra. The term is from the Greek roots spondylos, meaning vertebra, and lysis, meaning break or defect. Spondylolisthesis is from spondylos and listhesis, meaning movement or slipping, and refers to the slipping forward of one vertebra on the next caudal vertebra. Spondylolisthesis was first described in 1782 by...
Tugging and pulling in asymmetric cell divisions n asymmetric divisions, the cell alters the normal process that centers the spindle in the mother cell, but how it regulates the timing of spindle movement is unclear. Now, on page 245, Labbé et al. describe a tethering system that resists premature movement of the mitotic spindle during asymmetric cell divisions in C. elegans embryogenesis. It w...
This paper proposes a robust tracking controller based on a Generalized Extended State Observer (GESO) method for a wheeled mobile robot (WMR) with unknown skidding and slipping. Skidding and slipping of a WMR are inevitable in practice. We regard skidding and slipping as disturbances and modify the dynamics model to consider them simply. Then, we adopt the GESO to design...
It has been hypothesized that highly hypnotizable people spontaneously slip into trance when given imaginative suggestions without prior induction of hypnosis. We tested this in two studies. In Study 1, we examined state reports from ten highly suggestible students following the administration of a suggestion for altered colour perception. The suggestion was administered twice, once with and on...
The Additive Factors Model (AFM), a widely used model of student learning, estimates students’ prior knowledge, the difficulty of tutored skills, and the rates at which these skills are learned. In contrast to Bayesian Knowledge Tracing (BKT), another widely used model of student learning, AFM does not have parameters for the slipping rates of learned skills; i.e., it does not explicitly model ...
Central nervous system (CNS) involvement from breast cancer (BC) has been historically considered a relatively rare event. However, the development of new therapeutic strategies with a better control of extra-cranial disease and a longer overall survival (OS) has determined an increased incidence of brain metastases. Patients with HER2-positive or triple negative BC have higher occurrence of CN...
