Transient acoustic vaporization signatures unique to low boiling point phase change contrast agents enable super-resolution ultrasound imaging without spatiotemporal filtering

open access: yesAIP Advances, 2020
The unique activation signal of phase-change contrast agents (PCCAs or droplets) can be separated from the tissue signal and localized to generate super-resolution (SR) ultrasound (US) images.

Anisotropic multicomponent topology optimization for additive manufacturing with build orientation design and stress-constrained interfaces [PDF]

open access: yesarXiv, 2019
This paper presents a multicomponent topology optimization method for designing structures assembled from additively-manufactured components, considering anisotropic material behavior for each component due to its build orientation, distinct material behavior and stress constraint at component interfaces (i.e., joints).

The Longitudinal Relationship Between Pain and Depression in People with Inflammatory Arthritis: a Narrative Review

open access: yesArthritis Care &Research, Accepted Article.
As many patients with inflammatory arthritis (IA) have chronic pain, understanding how to best assess and manage pain in IA is a priority. Co‐morbid depression is prevalent in adults with IA, affecting 15 to 39% of people. Whilst pain and depression are thought to be associated in IA, this concept is largely based on cross‐sectional data.

Effect of Precursor Blending Ratio and Rotation Speed of Mechanically Activated Fly Ash on Properties of Geopolymer Foam Concrete

open access: yesBuildings
This research used fly ash and slag to create geopolymer foam concrete. They were activated with an alkali, resulting in a chemical reaction that produced a gel that strengthened the concrete’s structural integrity.

Generalized Mutual Information [PDF]

open access: yesarXiv, 2019
Mutual information is one of the essential building blocks of information theory. Yet, it is only finitely defined for distributions with fast decaying tails on a countable joint alphabet of two random elements. The unboundedness of mutual information over the general class of all distributions on a joint alphabet prevents its potential utility to be ...

Frequency Analysis of Temporal Graph Signals [PDF]

open access: yesarXiv, 2016
This letter extends the concept of graph-frequency to graph signals that evolve with time. Our goal is to generalize and, in fact, unify the familiar concepts from time- and graph-frequency analysis. To this end, we study a joint temporal and graph Fourier transform (JFT) and demonstrate its attractive properties.

Investing In Public Life [PDF]

open access: yes, 2005
At the end of the 20th century, civil investing emerged as one of the most important developments in American philanthropy. Not quite a philosophy, not quite a grantmaking strategy, and not quite a type of grant, civil investing can be broadly defined as
