Time-lenses for time-division multiplexing of optical OFDM channels.

Optics express

Geng Z, Corcoran B, Zhu C, Lowery AJ.
PMID: 26698462
Opt Express. 2015 Nov 16;23(23):29788-801. doi: 10.1364/OE.23.029788.

Time-lenses provide a promising platform for novel, broadband optical signal processing. However, in order to minimize system penalties, design constraints must be adequately taken into account. We investigate the impact of third-order-dispersion and nonlinear distortion on the performance of...

Widely-tunable low-phase-noise coherent receiver using an optical Wadley loop.

Optics express

Lowery AJ, Corcoran B, Zhu C.
PMID: 26367649
Opt Express. 2015 Jul 27;23(15):19891-900. doi: 10.1364/OE.23.019891.

The Wadley Loop is a method of down-converting RF signals over a wide frequency range using a low-quality widely-tunable oscillator and a high-stability frequency comb reference. Together the widely tunable oscillator and high-stability comb source provide a widely-tunable high-stability...

Integrated microwave photonic splitter with reconfigurable amplitude, phase, and delay offsets.

Optics letters

Zhuang L, Burla M, Taddei C, Roeloffzen CG, Hoekman M, Leinse A, Boller KJ, Lowery AJ.
PMID: 26625065
Opt Lett. 2015 Dec 01;40(23):5618-21. doi: 10.1364/OL.40.005618.

This work presents an integrated microwave photonics splitter with reconfigurable amplitude, phase, and delay offsets. The core components for this function are a dual-parallel Mach-Zehnder modulator, a deinterleaver, and tunable delay lines, all implemented using photonic integrated circuits. Using...

Socio-demographic patterns of posttraumatic stress disorder in Medellin, Colombia and the context of lifetime trauma exposure.

Disaster health

Gaviria SL, Alarcón RD, Espinola M, Restrepo D, Lotero J, Berbesi DY, Sierra GM, Chaskel R, Espinel Z, Shultz JM.
PMID: 28265488

Colombia, South America is currently transitioning to post-conflict status following 6 decades of armed conflict. The population has experienced extensive exposures to potentially traumatic events throughout the lifespan. Sources of trauma exposure include the prolonged armed insurgency, narco-trafficking violence,...

Interfacial Control of Magnetic Properties at LaMnO3/LaNiO3 Interfaces.

Nano letters

Gibert M, Viret M, Torres-Pardo A, Piamonteze C, Zubko P, Jaouen N, Tonnerre JM, Mougin A, Fowlie J, Catalano S, Gloter A, Stéphan O, Triscone JM.
PMID: 26484628

The functional properties of oxide heterostructures ultimately rely on how the electronic and structural mismatches occurring at interfaces are accommodated by the chosen materials combination. We discuss here LaMnO3/LaNiO3 heterostructures, which display an intrinsic interface structural asymmetry depending on...

Screening for cervical cancer in women with disability and multimorbidity: a retrospective cohort study in Ontario, Canada.

CMAJ open

Lofters A, Guilcher S, Glazier RH, Jaglal S, Voth J, Bayoumi AM.

BACKGROUND: People with disability, multiple chronic conditions or both may experience challenges in accessing primary care. We aimed to determine the association between appropriate cervical cancer screening and level of disability among women eligible for screening in Ontario and...

Comparisons of spectrally-enhanced asymmetrically-clipped optical OFDM systems.

Optics express

Lowery AJ.
PMID: 26907048
Opt Express. 2016 Feb 22;24(4):3950-66. doi: 10.1364/OE.24.003950.

Asymmetrically clipped optical orthogonal frequency-division multiplexing (ACO-OFDM) is a technique that sacrifices spectral efficiency in order to transmit an orthogonally frequency-division multiplexed signal over a unipolar channel, such as a directly modulated direct-detection fiber or free-space channel. Several methods...

TIPsy tour guides: how microtubule plus-end tracking proteins (+TIPs) facilitate axon guidance.

Frontiers in cellular neuroscience

Bearce EA, Erdogan B, Lowery LA.
PMID: 26175669
Front Cell Neurosci. 2015 Jun 30;9:241. doi: 10.3389/fncel.2015.00241. eCollection 2015.

The growth cone is a dynamic cytoskeletal vehicle, which drives the end of a developing axon. It serves to interpret and navigate through the complex landscape and guidance cues of the early nervous system. The growth cone's distinctive cytoskeletal...

MG-132, an inhibitor of proteasomes and calpains, induced inhibition of oocyte maturation and aneuploidy in mouse oocytes.

Cell & chromosome

Mailhes JB, Hilliard C, Lowery M, London SN.
PMID: 12437781
Cell Chromosome. 2002 Oct 08;1(1):2. doi: 10.1186/1475-9268-1-2.

BACKGROUND: Although chromosome missegregation during oocyte maturation (OM) is a significant contributor to human morbidity and mortality, very little is known about the causes and mechanisms of aneuploidy. Several investigators have proposed that temporal perturbations during OM predispose oocytes...
