    Abstract: A multi-party security protocol that incorporates biometric-based authentication and withstands attacks against any single party (e.g., mobile phone, cloud, or the user). The protocol involves the function split between mobile and cloud and the mechanisms to chain-hold the secrets. A key generation mechanisms binds secrets to a specific device or URL (uniform resource locator) by adding salt to a master credential. An inline CAPTCHA (Completely Automated Public Turing test to tell Computers and Humans Apart) handling mechanism uses the same sensor modality as the authentication process, which not only improves the usability, but also facilitates the authentication process. This architecture further enhances existing overall system security (e.g., handling untrusted or compromised cloud service, phone being lost, impersonation, etc.) and also improves the usability by automatically handling the CAPTCHA.

    Abstract: Methods of regenerating tissue using progenitor cells in combination with primary cells from a target tissue are disclosed. In particular, progenitor cells catalyze proliferation and tissue production by primary cells allowing the use of fewer primary cells from a target tissue for effective tissue regeneration. Cell-based therapies combining progenitor cells and primary cells can be used for repair and regeneration of damaged tissue and organs for treating bodily injuries and degenerative diseases. For example, adipose-derived stem cells and neonatal articular chondrocytes, co-encapsulated in mixed or bilayered cultures in a hydrogel comprising chondroitin sulfate methacrylate and poly(ethylene)glycol diacrylate, generated cartilage that could be used for treatment of traumatic injuries or diseases involving cartilage degeneration. Moreover, the inventors showed that progenitor cells could be used to stimulate cartilage formation with a minimal number of primary cells, as few as 1% or less, in mixed cultures containing primary cells and progenitor cells.

    Abstract: This disclosure provides systems, methods and apparatus relating to implementations of a switchable substrate that can be used in an imaging device. In one aspect, the switchable substrate includes a plurality of pixels, with each pixel having at least one switchable element. The switchable element can be switched between a first optical state and a second optical state. In the first optical state, a first spectral band of broadband light is reflected from the switchable element while a second spectral band is transmitted through the switchable element. In the second optical state, the first spectral band of the broadband light is transmitted through the switchable element while the second spectral band is reflected from the switchable element.

    Abstract: Devices and methods for fast, sensitive hydrogen gas detection using a single palladium nanowire. In one embodiment, a hydrogen sensor comprises a palladium nanowire extending between metal contacts. The palladium nanowire is not subject to fracturing when exposed to hydrogen. The nanowire is able to rapidly and reversibly detect hydrogen as a resistance increase down to 2 ppm with excellent reproducibility and baseline stability at room temperature.
