Demonstration of a 280  Gbit/s free-space space-division-multiplexing communications link utilizing plane-wave spatial multiplexing.

Optics letters

Lavery MP, Huang H, Ren Y, Xie G, Willner AE.
PMID: 26974062
Opt Lett. 2016 Mar 01;41(5):851-4. doi: 10.1364/OL.41.000851.

We demonstrate a 280 Gbit/s free-space space-division-multiplexing communications link incorporating a set of independent tilted truncated plane-waves, each generated by a single mode fiber placed at the back-focal plane of a spherical lens. Each of the seven tilted plane-wave...

Liposome Bupivacaine for Postsurgical Analgesia in Adult Patients Undergoing Laparoscopic Colectomy: Results from Prospective Phase IV Sequential Cohort Studies Assessing Health Economic Outcomes.

Current therapeutic research, clinical and experimental

Candiotti KA, Sands LR, Lee E, Bergese SD, Harzman AE, Marcet J, Kumar AS, Haas E.
PMID: 25031661
Curr Ther Res Clin Exp. 2013 Dec 27;76:1-6. doi: 10.1016/j.curtheres.2013.12.001. eCollection 2014 Dec.

BACKGROUND: Opioid-based postsurgical analgesia exposes patients undergoing laparoscopic colectomy to elevated risk for gastrointestinal motility problems and other opioid-related adverse events (ORAEs). The purpose of our research was to investigate postsurgical outcomes, including opioid consumption, hospital length of stay,...

Demonstration of Tunable Steering and Multiplexing of Two 28 GHz Data Carrying Orbital Angular Momentum Beams Using Antenna Array.

Scientific reports

Xie G, Zhao Z, Yan Y, Li L, Ren Y, Ahmed N, Cao Y, Willner AJ, Bao C, Wang Z, Liu C, Ziyadi M, Talwar S, Sajuyigbe S, Ashrafi S, Tur M, Molisch AF, Willner AE.
PMID: 27833168
Sci Rep. 2016 Nov 11;6:37078. doi: 10.1038/srep37078.

In line-of-sight communication systems, accurate alignment between the transmitter and receiver is important to guarantee sufficient signal power at the receiver. Such alignment is even more important for orbital angular momentum (OAM) multiplexing systems since misalignment between the transmitter...

Localization from the unique intensity gradient of an orbital-angular-momentum beam.

Optics letters

Xie G, Li L, Ren Y, Yan Y, Ahmed N, Zhao Z, Bao C, Wang Z, Liu C, Song H, Zhang R, Pang K, Ashrafi S, Tur M, Willner AE.
PMID: 28146485
Opt Lett. 2017 Feb 01;42(3):395-398. doi: 10.1364/OL.42.000395.

We propose and simulate the use of the unique intensity gradient of beams carrying orbital angular momentum (OAM) for tracking and localization of an object. We design a three-pixel detector structure to efficiently determine the intensity gradient of an...

Molecular-like hierarchical self-assembly of monolayers of mixtures of particles.

Scientific reports

Singh P, Hossain M, Gurupatham SK, Shah K, Amah E, Ju D, Janjua M, Nudurupati S, Fischer I.
PMID: 25510331
Sci Rep. 2014 Dec 16;4:7427. doi: 10.1038/srep07427.

We present a technique that uses an externally applied electric field to self-assemble monolayers of mixtures of particles into molecular-like hierarchical arrangements on fluid-liquid interfaces. The arrangements consist of composite particles (analogous to molecules) which are arranged in a...

Lipid Bilayers: The Effect of Force Field on Ordering and Dynamics.

J Chem Theory Comput. 2012 Nov 13;8(11):4807-17. doi: 10.1021/ct300675z. Epub 2012 Oct 18.

The sensitivity of the structure and dynamics of a fully hydrated pure bilayer of 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) in molecular dynamics simulations to changes in force-field and simulation parameters has been assessed. Three related force fields (the Gromos 54A7 force field,...

Population dynamics with regard to evolution of traits has typically been studied using matrix projection models (MPMs). Recently, to work with continuous traits, integral projection models (IPMs) have been proposed. Imitating the path with MPMs, IPMs are handled first...

Activating the Prolactin Receptor: Effect of the Ligand on the Conformation of the Extracellular Domain.

Journal of chemical theory and computation

Groothuizen FS, Poger D, Mark AE.
PMID: 26616789
J Chem Theory Comput. 2010 Oct 12;6(10):3274-83. doi: 10.1021/ct1003934.

The prolactin receptor resides on the surface of the cell as a preformed dimer. This suggests that cell signaling is triggered by conformational changes within the extracellular domain of the receptors. Here, by using atomistic molecular dynamics simulations, we...
