    Abstract: An aerial device is provided. The aerial device includes a processor and a memory that includes instructions configured to cause the processor to perform certain operations when the processor executes the instructions. The operations may include receiving a first signal indicative of a first position of the aerial device. The operations may also include generating, based on the first signal and based on a randomly or pseudo-randomly generated sequence, a second signal configured to actuate flight hardware of the aerial device to a second position.

    Abstract: A method for treating against, or at least inhibiting or suppressing, the proliferation of an internal ribosome entry site-utilizing virus (IRES-utilizing virus) involves administering a compound, a tautomer, or a pharmaceutically acceptable salt thereof, in an amount effective for inhibiting replication of the IRES-utilizing virus in cells, wherein the compound is represented by the formula: wherein each R1 is independent of the other and represents a halogen atom selected from the group consisting of bromo, chloro, fluoro and iodo.

    Abstract: A method, computer program, and computer system is provided for analyzing chemical mixtures. Data corresponding to a mixture comprising one or more component species is obtained. A parameter corresponding to a species having a largest parameter value within the mixture is determined from among the component species. The parameter associated with the species having the largest parameter value is subtracted from the data. One or more remaining species associated with the mixture are detected.

    Abstract: A myocardial blood flow analysis scan includes incorporating a pharmacological kinetic model with the standard factor analysis model where each time activity curve is assumed to be a linear combination of factor curves. Pharmacological kinetics based factor analysis of dynamic structures (K-FADS-II) model can be applied, whereby estimating factor curves in the myocardium can be physiologically meaningful is provided. Additional optional aspects include performing a discretization to transform continuous-time K-FADS-II model into a discrete-time K-FADS-II model and application of an iterative Improved Voxel-Resolution myocardial blood flow (IV-MBF) algorithm. Where the model is applied without assumption that a right ventricle tissue curve and a left ventricle tissue curve obey a particular mathematical relationship, a least squares objective function can be applied to obtain estimates for parameters of the pharmacological kinetic model by applying a majorize-minimize optimization technique to iteratively estimate the curves.

    Abstract: Methods and compositions are provided for reducing transmission and/or infection of HIV in a subject by increasing the bioavailability of a drug in the subject. The methods and compositions provided herein include an efflux transporter inhibitor and a drug effective for reducing the transmission and/or infection of HIV in a subject. The efflux transporter inhibitor is effective to reduce the efflux of the drug through at least one of P-glycoprotein (Pgp), breast cancer resistant protein (BCRP), and multidrug resistant associated protein 1-9 (MRP1-9).

    Abstract: A redundant and diverse secondary control system mirrors a primary control system but has some fundamental structural difference as compared to the primary control system to prevent a spread of a security breach from the primary control system to the secondary control system. The secondary control system may operate on different hardware built on different software written with different programming language as compared to the primary control system while performing the same function as that of the primary system. By hardware coding the algorithm to produce actuation signals, software based viruses and worms cannot interfere with the secondary control system's operation. A monitor device receives actuation signals from both the primary and secondary controls signals to determine whether an error occurred and to provide correct actuation signals to the controlled system.
