Comparison of 3-D synthetic aperture phased-array ultrasound imaging and parallel beamforming.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control

Rasmussen MF, Jensen JA.
PMID: 25265174
IEEE Trans Ultrason Ferroelectr Freq Control. 2014 Oct;61(10):1638-50. doi: 10.1109/TUFFC.2014.006345.

This paper demonstrates that synthetic aperture imaging (SAI) can be used to achieve real-time 3-D ultrasound phased-array imaging. It investigates whether SAI increases the image quality compared with the parallel beamforming (PB) technique for real-time 3-D imaging. Data are...

Vascular rejection in cardiac transplantation: Histologic, immunopathologic, and ultrastructural features.

Hammond EH, Hansen JK, Spencer LS, Jensen A, Riddell D, Craven CM, Yowell RL.
PMID: 25990520
Cardiovasc Pathol. 1993 Jan-Mar;2(1):21-34. doi: 10.1016/1054-8807(93)90010-Y.

Although the majority of rejection found in cardiac transplant biopsies is cellular in type, a variety of vascular alterations occur in cardiac biopsies, constituting different forms of rejection that can be recognized using light microscopic and immunopathologic criteria. In...

Synthesis and Pharmacological Evaluation of DHβE Analogues as Neuronal Nicotinic Acetylcholine Receptor Antagonists.

ACS medicinal chemistry letters

ACS Med Chem Lett. 2014 May 20;5(7):766-70. doi: 10.1021/ml500094c. eCollection 2014 Jul 10.

Dihydro-β-erythroidine (DHβE) is a member of the Erythrina family of alkaloids and a potent competitive antagonist of the α4β2-subtype of the nicotinic acetylcholine receptors (nAChRs). Guided by an X-ray structure of DHβE in complex with an ACh binding protein,...

Dietary choice for a balanced nutrient intake increases the mean and reduces the variance in the reproductive performance of male and female cockroaches.

Ecology and evolution

Bunning H, Bassett L, Clowser C, Rapkin J, Jensen K, House CM, Archer CR, Hunt J.
PMID: 27547307
Ecol Evol. 2016 Jun 12;6(14):4711-30. doi: 10.1002/ece3.2243. eCollection 2016 Jul.

Sexual selection may cause dietary requirements for reproduction to diverge across the sexes and promote the evolution of different foraging strategies in males and females. However, our understanding of how the sexes regulate their nutrition and the effects that...

Multistage extraction platform for highly efficient and fully continuous purification of nanoparticles.

Nanoscale

Shen Y, Weeranoppanant N, Xie L, Chen Y, Lusardi MR, Imbrogno J, Bawendi MG, Jensen KF.
PMID: 28561116
Nanoscale. 2017 Jun 14;9(23):7703-7707. doi: 10.1039/c7nr01826f.

This paper presents a fully-continuous novel liquid-liquid-extraction (LLE) platform for the purification of nanoparticles. The use of multistage operation enhances the purity of the final stream without the expense of high solvent consumption. Two case studies, purification of CdSe...

Constraint on Defect and Boundary Renormalization Group Flows.

Physical review letters

Jensen K, O'Bannon A.
PMID: 26991169
Phys Rev Lett. 2016 Mar 04;116(9):091601. doi: 10.1103/PhysRevLett.116.091601. Epub 2016 Mar 03.

A conformal field theory (CFT) in dimension d≥3 coupled to a planar, two-dimensional, conformal defect is characterized in part by a "central charge" b that multiplies the Euler density in the defect's Weyl anomaly. For defect renormalization group flows,...

Characterization of Indium Phosphide Quantum Dot Growth Intermediates Using MALDI-TOF Mass Spectrometry.

Journal of the American Chemical Society

Xie L, Shen Y, Franke D, Sebastián V, Bawendi MG, Jensen KF.
PMID: 27690411
J Am Chem Soc. 2016 Oct 19;138(41):13469-13472. doi: 10.1021/jacs.6b06468. Epub 2016 Oct 06.

Clusters have been identified as important growth intermediates during group III-V quantum dot (QD) formation. Here we report a one-solvent protocol that integrates synthesis, purification, and mass characterization of indium phosphide (InP) QD growth mixtures. The use of matrix-assisted...

Acoustical cross-talk in row-column addressed 2-D transducer arrays for ultrasound imaging.

Ultrasonics

Christiansen TL, Jensen JA, Thomsen EV.
