RodentSQL: A software suite for colony management of animal protocols

Most of the mouse experiments tend to generate a large-scale data, which is needed to be stored and eventually made publicly available. Many research groups still struggle to have central storage and integrated management system of this metadata. Some existing tools like Microsoft excel sheets and couple other colony management web/cloud-based tools are either cumbersome or expensive. There seems a constant need for...

Continuous frame in Hilbert space and its applications

In this paper, we study continuous frames in Hilbert spaces using a family of linearly independent vectors called coherent state (CS) and applying it in any physical space. To accomplish this goal, the standard theory of frames in Hilbert spaces, using discrete bases, is generalized to one where the basis vectors may be labeled using discrete, continuous or a mixture of the two types of indices.  A comprehensive...
