    摘要： The present disclosure relates to methods of preparing protein hydrogels and to protein hydrogels which may, for example, be prepared from such methods. The methods comprise denaturing a protein in an aqueous environment to produce an aqueous composition comprising overlapping polypeptide chains; crosslinking the polypeptide chains to produce a denatured protein hydrogel comprising a crosslinked network of entangled polypeptide chains; and optionally at least partially renaturing the denatured protein hydrogel.

    摘要： A method of providing an authenticator for an event includes capturing first information of the event, obtaining a first distillation of the first information of the event. The method also includes digitally signing the first distillation of the information of the event to provide a digitally signed first distillation, and providing the digitally signed first distillation during the event for embedding into the event. The method may include obtaining a recording of the event including a digital signature and a purported first distillation, generating a second distillation of information from the second recording, authenticating the purported first distillation of information utilizing a public key associated with the private key utilized to create the digital signature, and conducting a comparison of the second distillation of the event to the purported first distillation.

    摘要： Helmet prevent or mitigate cervical spine fractures, including the type of injuries associated with axial compression of the spine and fracture of the spine which may otherwise result in deformation and/or injury to the spinal cord. Helmets convert an impact force with a component aligned with the axis of the spine (a “spinally axial component”) to rotational motion. In the event of a head-first impact, such helmets flexion of the neck so that the head and the cervical spine are not aligned (or less aligned) with the direction of an impact force, thereby mitigating the likelihood and/or severity of cervical spine fractures.
