[HTML][HTML] Saving phase: Injectivity and stability for phase retrieval
Recent advances in convex optimization have led to new strides in the phase retrieval problem
over finite-dimensional vector spaces. However, certain fundamental questions remain: …

Certifying the restricted isometry property is hard
This paper is concerned with an important matrix condition in compressed sensing known
as the restricted isometry property (RIP). We demonstrate that testing whether a matrix …

Steiner equiangular tight frames
We provide a new method for constructing equiangular tight frames (ETFs). The construction
is valid in both the real and complex settings, and shows that many of the few previously-…

Full spark frames
Finite frame theory has a number of real-world applications. In applications like sparse
signal processing, data transmission with robustness to erasures, and reconstruction without …

Phase retrieval with polarization
In many areas of imaging science, it is difficult to measure the phase of linear measurements.
As such, one often wishes to reconstruct a signal from intensity measurements, that is, …

Sparse phase retrieval from short-time Fourier measurements
We consider the classical 1D phase retrieval problem. In order to overcome the difficulties
associated with phase retrieval from measurements of the Fourier magnitude, we treat …

The road to deterministic matrices with the restricted isometry property
The restricted isometry property (RIP) is a well-known matrix condition that provides state-of-the-art
reconstruction guarantees for compressed sensing. While random matrices are …

Tables of the existence of equiangular tight frames
A Grassmannian frame is a collection of unit vectors which are optimally incoherent. To date,
the vast majority of explicit Grassmannian frames are equiangular tight frames (ETFs). This …

In vitro investigation of the biological effects associated with human dermal fibroblasts exposed to 2.52 THz radiation
Background Terahertz (THz) radiation sources are increasingly being used in military,
defense, and medical applications. However, the biological effects associated with this type of …

Neural collapse with unconstrained features
Neural collapse is an emergent phenomenon in deep learning that was recently discovered
by Papyan, Han and Donoho. We propose a simple "unconstrained features model" in …
