Method for evaluating the solubility of a crystalline substance in a polymer

A viable strategy to enhance the bioavailability of poorly soluble drugs is to use amorphous solids in place of the more commonly used crystalline solids in pharmaceutical formulations. However, amorphous solids are physically meta-stable and tend to revert back to their crystalline counterpart. An effective approach to stabilizing an amorphous drug against crystallization is to disperse it in a polymer matrix. The drug's solubility in the chosen polymer defines the upper limit of drug loading without any risk of crystallization. Measuring the solubility of a drug in a polymer has been a scientific and technological challenge because the high viscosity of polymers makes achieving solubility equilibrium difficult and because pharmaceutically important drug/polymer dispersions are glasses, which undergo structural relaxation over time. The invention provides a method based on Differential Scanning Calorimetry (DSC) for measuring the solubility of crystalline drugs in polymeric matrices. The method relies on the detection of the dissolution endpoint of a drug/polymer mixture prepared by cryomilling.

Provided are a method and apparatus for enabling a main stream to refer to an elementary stream existing in another simple aggregation format (SAF) session by using a global ID during provision of a light application scene representation (LASeR) service, and a LASeR service providing apparatus. In order for a main stream to refer to an elementary stream included in an SAF session different from an SAF session in which the main stream is included without a change of existing LASeR and SAF stream structures, the main stream for a LASeR service uses a global stream ID of the elementary stream as a reference value. Accordingly, the elementary stream included in the SAF session different from the SAF session of the main stream can be effectively referred to without need to create a separate apparatus or change an existing apparatus even when a global ID included in a LASeR scene description is used as in the conventional art.

Non-line-of-sight detection

A wireless device can perform non-line-of-sight detection. The wireless device may establish a wireless link with another wireless device using a wireless channel. The wireless device may perform one or more channel measurements for the wireless channel. The wireless device may determine whether a line-of-sight path is available for the wireless channel based at least in part on the one or more channel measurements. The wireless device may determine whether to trigger beamforming selection, antenna selection, and/or any other link maintenance operations based at least in part on the determined line-of-sight availability.
