The method comprises sharing a first secret key with a message-sending node, sharing a second secret key with a message-receiving node, generating a first trusted-node signature by performing a partial QKD process together with the message-sending node, generating a second trusted-node signature by performing a partial QKD process together with the message-receiving node, and verifying a first message with the shared first and second secret keys and with the first and second trusted-node signatures.

Abstract: Disclosed is a sustained-release lipid pre-concentrate. The sustained-release lipid pre-concentrate forms liquid crystals when exposed to an aqueous medium, thus enabling the sustained-release of a drug, and can sustain drug release for two weeks to one month. In addition, the formed liquid crystals are sustainably released even at low viscosity, and have excellent ease of use due to low extrusion force when injected.

Abstract: Systems, methods, and apparatuses for implementing a digital personal assistant. The digital personal assistant determining that a user has initiated a user experience with it. In response, the digital personal assistant collects information concerning the user's sensibilities about content and a current context in which the digital personal assistant is being used. With that information, the digital personal assistant infers facets of the user's sensibilities and deduces a context of use. With those inferences and that deduction, the digital personal assistant evaluates whether the presentation of responsive content should be modified to better comport with the user's sensibilities and to be more appropriate for the context of use. Additionally, in response to determining a user's need for content, the digital personal assistant can use the inference and deduction to supply suggested content to the user.
