Under appropriate pump actuation the selected modes produce circumferential laser radiation with the output surface comprising of the entire outer perimeter of the cylindrical ring waveguide. The design is applicable toward both micro-resonators and resonators much larger than the optical wavelength, enabling high output powers and scalability. The circumferential radial laser emission can be concentrated by positioning the cylindrical ring laser inside a three-dimensional conical mirror thereby forming a laser ring of light propagating in the axial dimension away from the surface of the laser, which can be subsequently collimated for focused using conventional optics. |

Quantum random, self-modifiable computer
We describe a computing machine, called a quantum random, self-modifiable computer, that uses self-modification and randomness to enhance the computating power. Sometimes it is called an ex-machine, derived from the latin extra machinam because its can evolve as it computes so that its complexity increases without an upper bound. In an embodiment, an ex-machine program can compute languages that a Turing or standard machine cannot compute. In an embodiment, the ex-machine has three types of instructions: standard instructions, meta instructions and random instructions. In an embodiment, the meta instruction self-modify the machine as it is executing so that new instructions are added. In an embodiment, the standard instructions are expressed in the C programming language or a hardware description language such as VHDL. Random instructions take random measurements from a random source. In an embodiment, the random source produces quantum events which are measured during the machine's execution.In an embodiment, an ex-machine receives a computer program as input, containing only standard instructions. In an embodiment, the ex-machine combines its random instructions and its meta instructions to self-modify the ex-machine instructions, so that it can evolve to compute (i.e., verify) the correctness of the computer program that it received as input. In an embodiment, an ex-machine uses its meta instructions and random instructions to improve its machine learning procedures as the ex-machine is computing.In an embodiment, machine computation that adds randomness and self-modification to the standard digital computer instructions has more computing capability than a standard digital computer. This capability enables more advanced machine learning procedures where in some embodiments meta instructions and random instructions improve the machine learning procedure, as it is executing. In an embodiment, differential forms, the curvature tensor, and curvature of saddle points are used to help self-modify and improve an initial, standard gradient descent method. |

In response to receiving from the host a read request designating a physical address indicative of a physical storage location of the nonvolatile memory, the controller reads both the encrypted data and the first address from the nonvolatile memory on the basis of the physical address, and decrypts the read encrypted data with the first encryption key and the read first address. |

System and method for detecting source code anomalies
A system includes a source code repository which stores source code entries, which include instructions in a programming language for performing computing tasks. A style repository stores a style profile. Each style profile includes predefined style features associated with formatting characteristics of the stored source code entries. A source code analyzer receives a source code which includes instructions in the programming language for performing a computing task. Style features of the source code are determined. The style features include characteristics of a format of the source code. The source code analyzer determines whether the style features correspond to predefined style features indicated by a style profile. If this is the case, the source code is stored in the source code repository. If this is not the case, storage of the source code is prevented. |

Request control device, request control method, and request control program
A request control device, when receiving a request issued from a client to a Web system, causes a sandbox in which an environment of the Web system is reproduced to inspect the request. The request control device transfers the request to the Web system if an inspection result of the request in the sandbox does not indicate detection of an attack. The request control device does not transfer the request to the Web system if the inspection result of the request indicates detection of an attack. |

Stateless password manager
A first application name is received. For example, the first application name may be the name of the application, a Universal Resource Locator (URL) of a web site (e.g., microfocus.com), and/or the like. The first application name represents a computer application of a plurality of computer applications that the user logs into. A global password is received from the user. The global password is used as a seed to login to the plurality of computer applications. The global password is converted to a phonetic password. A first application password is generated for the first computer application based on the first application name and the phonetic password. For example, the first application name and the phonetic password are used as an input to a key deviation function. The first application password is then displayed to the user. The user can then use the displayed password to login to the first application. |

Systems and methods of multi-modal biometric analysis
Exemplary embodiments are directed to a multi-modal biometric analysis system including one or more illumination sources, one or more cameras, and a processing device. The illumination sources are configured to illuminate an iris of a subject. The cameras are configured to capture one or more images of the subject during illumination of the subject with the one or more illumination sources. The images include iris biometric data associated with the iris of the subject and face biometric data associated with a face of the subject. The processing device receives as input the one or more images, analyzes the iris biometric data for iris biometric authenticity, analyzes the face biometric data for face biometric authenticity, and compares the iris biometric data and the face biometric data to determine the biometric authenticity of the subject. |

Method and apparatus to dynamically control facial illumination
Systems and methods for authenticating a user in an authentication system using a computing device configured to capture authentication biometric identity information. The authentication biometric identify information captured during an authentication session. The authentication biometric identify information may comprise or be derived from one or more images of the user being authenticated. The authentication biometric identify information is compared to root identify biometric information. The root identify biometric information is captured from a trusted source, such as trusted devices located at trusted locations, such as a government entity, financial institution, or business. Identity verification may occur by comparing the trusted root identify biometric information to the biometric identify information captured during an authentication session. Liveness determination may also occur to verify the user is a live person. Liveness determination may include comparing two images of the user such that the two images are captured at different distances from the user. |
