The composite cylindrical roller is composed of a hollow cylindrical roller and a filler body and is a new type sex-swings of structure roller bearing.In order to explore the influence of different parameters on the contact characteristics and vibration characteristics of bearings, finite element models of static contact, modal analysis, and harmon
Background: Food allergy prevalence has continued to rise over the past decade.While studies have reported threshold doses for multiple foods, large-scale multi-food allergen studies are lacking.Our goal was to identify threshold dose distributions and predictors of severe reactions during blinded oral food challenges (OFCs) in multi-food allergic
Introduction: the progressive hemifacial atrophy or Parry-Romberg syndrome is a rare disease, of slow clinical evolution that generates atrophy of the soft tissues.It compromises frequently only one side of the face, where the left side is the most affected.The disease usually establishes in early ages and with the time it could compromise one or m
Abstract The low-dimensional, highly anisotropic geometries, and superior mechanical properties of one-dimensional (1D) nanomaterials allow the exquisite strain engineering with a broad tunability inaccessible to bulk or thin-film materials.Such capability enables unprecedented possibilities for probing intriguing physics and materials science in t
