Functionally graded ferroelectric polyetherimide composites for high temperature sensing
High temperature ferroelectrics for thermally stable devices that can detect pressure and temperature are of great industrial interest. Here we describe composites of lead titanate (PT) particle-polyetherimide (PEI) polymers...

Hyperconnectivity of the ventromedial prefrontal cortex in obsessive-compulsive disorder.
Annemieke M Apergis-Schoute, Bastiaan Bijleveld, Claire M Gillan, Naomi A Fineberg, Barbara J Sahakian, Trevor W Robbins
Jan 03, 2020
Neuroimaging research has highlighted maladaptive thalamo-cortico-striatal interactions in obsessive-compulsive disorder as well as a more general deficit in prefrontal functioning linked with compromised executive functioning....
1064 nm laser-induced defects in pure SiO<sub>2</sub> fibers
We investigate evidence of the formation of nonbridging oxygen hole centers in pure silica photonic crystal fibers from 5 ps 1064 nm pulses. The formation of the defects is attributed to the breaking of stressed silicon-oxygen...
Highly birefringent 98-core fiber
We report on the fabrication and characterization of a polarization- maintaining multicore fiber. The fiber has 98 aligned cores, each with a birefringence of ≈2.3 × 10. The beat length, polarization extinction ratio, and...
Mesoscopic kinetic Monte Carlo modeling of organic photovoltaic device characteristics
Measured mobility and current-voltage characteristics of single layer and photovoltaic (PV) devices composed of poly{9,9-dioctylfluorene-co-bis[N,N -(4-butylphenyl)]bis(N,N-phenyl-1,4- phenylene)diamine} (PFB) and...

Time-dependent degradation of photonic crystal fiber attenuation around OH absorption wavelengths
We present a study of the time-dependent degradation of attenuation in Photonic Crystal Fibers in the wavelength region from 1350 nm to 1450 nm. Changes in spectral attenuation were monitored over 16 weeks of exposure to a...
Efficient diode-pumped mid-infrared emission from acetylene-filled hollow-core fiber
We report 3.1-3.2 μm mid-infrared emission from acetylene-filled low loss antiresonant hollow-core fiber pumped with an amplified, modulated, narrowband, tunable 1.5 μm diode laser. The maximum power conversion efficiency of...

Efficient 1.9 μm emission in H-filled hollow core fiber by pure stimulated vibrational Raman scattering
We report here efficient 1.9 μm emission by pure stimulated vibrational Raman scattering in a hydrogen-filled anti-resonant hollow-core fiber pumped with a 1064 nm microchip laser. A maximum quantum conversion efficiency ∼48%...

Temperature response of an all-solid photonic bandgap fiber for sensing applications
The spectral shift due to temperature in the photonic bandgap (PBG) of an all-solid PBG fiber is investigated, aiming at discrete and distributed temperature sensing. A temperature rise induces a red shift in the bandgap...

Femtosecond pulses at 20 GHz repetition rate through spectral masking of a phase modulated signal and nonlinear pulse compression
We present a laser system capable of producing 190 femtosecond pulses at a repetition rate of 20 GHz. The spectral masking of a phase modulated diode laser is used to produce a train of picosecond pulses which are compressed...
Flexible delivery of Er:YAG radiation at 2.94 μm with novel hollow-core silica glass fibres
In this work we present the delivery of high energy Er:YAG laser pulses operating at 2.94 μm through a hollow-core negative curvature fibre (HC-NCF) and a hollow-core photonic crystal fibre (HC-PCF) and their use for the...
The BTZ black hole violates strong cosmic censorship
Abstract: We investigate the stability of the inner horizon of a rotating BTZ black hole. We show that linear perturbations arising from smooth initial data are arbitrarily differentiable at the inner horizon if the black hole...

Holographic dual of hot Polchinski-Strassler quark-gluon plasma
Abstract: We construct the supergravity dual of the hot quark-gluon plasma in the mass-deformed N = 4 Super-Yang-Mills theory (also known as N = 1∗). The full ten-dimensional type IIB holographic dual is described by 20...
