Active matrix factorization for surveys [PDF]
The Annals of Applied Statistics, 2020 Amid historically low response rates, survey researchers seek ways to reduce respondent burden while measuring desired concepts with precision. We propose to ask fewer questions of respondents and impute missing responses via probabilistic matrix factorization.

Lossy Microwave Filters With Active Shape Correction
IEEE Access, 2021 Obtaining the prescribed microwave filter response is highly desirable for proper frequency selectivity in RF transceivers. As the traditional microwave filter design methods do not take into account finite unloaded quality factors, lossy resonators ...

Matrix metalloproteases and PAR1 activation [PDF]
Blood, 2013 AbstractCardiovascular diseases, including atherothrombosis, are the leading cause of morbidity and mortality in the United States, Europe, and the developed world. Matrix metalloproteases (MMPs) have recently emerged as important mediators of platelet and endothelial function, and atherothrombotic disease.

Antibacterial activity of matrix-bound ovotransferrin [PDF]
Antimicrobial Agents and Chemotherapy, 1982 Ovotransferrin immobilized by covalent linkage to Sepharose 4B showed a bacteriostatic effect towards Escherichia coli similar to that of free ovotransferrin. The growth of the bacteria, after exposure to the gel-bound ovotransferrin and its removal, depended on the length of exposure.
