Abstract: The field of various phototriggered drug release and photoreactions, including reactions generally based on triplet-triplet energy transfer with light excitation at long wavelengths. Systems and methods for absorbing energy in a photosensitizer, and methods for making or using such systems, kits including such systems. The systems and methods comprise transferring that energy by triplet-triplet energy transfer to cleave a cleavable or other active moiety, for instance, in order to cause the release of a releasable moiety. In some cases, these may be contained within a suitable carrier material, for example, a particle or a micelle. Such systems and methods may be used in a variety of applications, including various biological or physical applications. For example, such systems and methods may be useful for delivering drugs or other releasable moieties to regions of a subject.

Abstract: A methods and systems for determining rounded contours of target contours or other lithography related contour for mask design. The method includes converting a contour representation to (i) a first set of contour point locations in a first dimension (e.g., x) and (ii) a second set of contour point locations in a second dimension (e.g., y). A signal function is determined based on the first and second sets of contour point locations, the signal function indicative of different segments of the contour representation. The first set of contour point locations is updated based on a first filter function and the signal function, and the second set of contour point locations is updated based on a second filter function and the signal function. Based on the updated contour point locations, a rounded contour of the contour representation is generated.
