Completely Positive Biquadratic Tensors
In this paper, we systemically introduce completely positive biquadratic (CPB) tensors and copositive biquadratic tensors. We show that all weakly CPB tensors are sum of squares tensors, the CPB tensor cone and the copositive biquadratic tensor cone are dual cone to each other. We also show that the outer product of two completely positive matrices is a CPB tensor, and the outer product of two copositive matrices is a copositive biquadratic tensor. We then study two easily checkable subclasses …

A continued fraction approximation for the effective elasticity tensor of two-dimensional polycrystals as a function of the crystal elasticity tensor
For two-dimensional polycrystals the effective elasticity tensor $C_*$ as a function $C_*(C_0)$ of the elasticity tensor $C_0$ of the constituent crystal is considered. It is shown that this function can be approximated by one with a continued fraction expansion resembling that associated with a class of microstructure known as sequential laminates. These are hierarchical microstructures defined inductively. Rank 0 sequential laminates are simply rotations of the pure crystal. Rank $j$ sequenti…

A novel imaging solution, called
"prostate-specific membrane antigen (PSMA) positron emission tomography (PET) scanning",
can more effectively detect the recurrence of prostate cancer
compared to standard imaging methods,
and is associated with improved survival outcomes.

New imaging technique boosts survival in prostate cancer patients
A multicenter study led by London Health Sciences Centre Research Institute (LHSCRI), Lawson Research Institute of St. Joseph's Health Care London (Lawson), and University Health Network (UHN) has found a novel imaging solution, called prostate-specific membrane antigen (PSMA) positron emission tomography (PET) scanning, can more effectively detect the recurrence of prostate cancer compared to standard imaging methods, and is associated with improved survival outcomes.

Tensor Logic: The Language of AI
Progress in AI is hindered by the lack of a programming language with all the requisite features. Libraries like PyTorch and TensorFlow provide automatic differentiation and efficient GPU implementation, but are additions to Python, which was never intended for AI. Their lack of support for automated reasoning and knowledge acquisition has led to a long and costly series of hacky attempts to tack them on. On the other hand, AI languages like LISP an Prolog lack scalability and support for learn…

LEGO: Spatial Accelerator Generation and Optimization for Tensor Applications
Modern tensor applications, especially foundation models and generative AI applications require multiple input modalities (both vision and language), which increases the demand for flexible accelerator architecture. Existing frameworks suffer from the trade-off between design flexibility and productivity of RTL generation: either limited to very few hand-written templates or cannot automatically generate the RTL. To address this challenge, we propose the LEGO framework, which targets tensor app…
