Abstract: The disclosed embodiments concern methods, apparatus, systems, and computer program products for developing polygenic risk score (PRS) models. In some implementations, a fully automated process is provided that allows for a PRS model to be defined by an initial set of parameters. In some implementations the PRS models are trained to provide a PRS for particular populations.

Abstract: A wheelchair luggage towing device to securely attach a luggage to the back of a wheelchair and pull the luggage along with the wheelchair. The device can be used with wheeled, as well as unwheeled luggage using a wheeled luggage carrier. The device comprises of a single or multiplicity of bars. A single bar is used with wheelchairs which have long vertical bars on their back. Two bars are used with wheelchairs which have a horizontal bar at their upper back. And three bars are used with wheelchairs which have two short vertical bars and no horizontal bar. In this case, a first bar is connected horizontally to the vertical bars of the wheelchair. A second bar is connected vertically to the first bar. And a third bar is connected horizontally to the lower end of the second bar. In all cases, the luggage is secured on the horizontal bar located close to the ground.

A single bar is used with wheelchairs which have long vertical bars on their back. In this case, a bar is horizontally connected to the vertical bars at the back of the wheelchair so that a luggage can be secured on it. Two bars are used with wheelchairs which have a horizontal bar at their upper back. In this case, one bar is vertically connected to the horizontal bar and the second bar is connected to the lower end of the horizontal bar. Three bar combination is used with wheelchairs which have two short vertical bars and no horizontal bar. In this case, the first bar is connected horizontally to the vertical bars of the wheelchair. The second bar is connected vertically to the first bar.
