Polarisation effects in optical microcoil resonators
Optical microcoil resonators (OMRs) fabricated by wrapping a microfibre around a rod to allow evanescent coupling between adjacent turns as in Fig 1. (a) have recently attracted much interest due to their high Q-factor and large extinction ratios resonances, low input and output coupling losses, large evanescent field and compactness [1,2], with applications such as sensing [3] and signal processing [4]. However, theoretical models published so far have neglected polarisation effects, and hence in order to develop a more detailed understanding we have modelled the OMR with polarisation-dependent coupled mode equations in the linear [5] and nonlinear regimes
Theoretical study of noise reduction of NRZ signals using nonlinear broken micro-coil resonators
Nonlinear microcoil resonators are extremely attractive devices for nonlinear optics; however, due to their high-Q values, their use at high speeds is limited. In this letter, we analyze a simple way of increasing their bandwidth, namely breaking the fiber in several places, and show that the resulting device is suitable for noise reduction in realistic systems. Simulations show that an in-line broken resonator can significantly reduce the impact of amplitude noise on the bit-error rate of nonreturn-to-zero signals
Proton-exchanged lithium niobate waveguides for photonic applications
This talk shall provide an overview of the current activity on integrated LiNbO3 devices based on proton-exchange techniques at the ORC. We shall present the technology and the experimental results obtained so far on slab waveguides in 2D Nonlinear Photonic Crystals and on channel waveguides in Periodically Poled Lithium Niobate and discuss perspective applications for all-optical signal processing in ultra-fast fibre telecom systems
Numerical model for a widely tunable self-similar oscillator
We propose a design for a widely tunable oscillator operating over the wavelength range 1µm to 2µm. Numerical simulations show that the pulses evolve self-similarly in each stage of the oscillator maintaining a hyperbolic secant form
Performance and Professional Wrestling
Performance and Professional Wrestling is the first edited volume to consider professional wrestling explicitly from the vantage point of theatre and performance studies. Moving beyond simply noting its performative qualities or reading it via other performance genres, this collection of essays offers a complete critical reassessment of the popular sport.
Topics such as the suspension of disbelief, simulation, silence and speech, physical culture, and the performance of pain within the squared circle are explored in relation to professional wrestling, with work by both scholars and practitioners grouped into seven short sections:
Audience
Circulation
Lucha
Gender
Queerness
Bodies
Race
A significant re-reading of wrestling as a performing art, Performance and Professional Wrestling makes essential reading for scholars and students intrigued by this uniquely theatrical sport
Vincent L. Broderick - A Distinguished Jurist and Great Teacher
Judge Broderick had a wonderful sense of humor and taught our law students, the bench and bar, and his colleagues, to be stronger professionals and better human beings. He will be sorely missed by the faculty, deans, students, and alumnae of the Pace University School of Law
Modeling large air fraction holey optical fibers
We develop a modal decomposition approach to solve the full vector wave equation for holey optical fibers (HF). This model can be used to explore the modal properties of a wide range of HFs, including those with large air holes. The optical properties of HF can be tailored via the arrangement of the air holes, and this flexibility leads to a wide range of practical applications
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Effects of alfalfa silage storage structure and roasting corn on ruminal digestion and microbial CP synthesis in lactating dairy cows
The objective of this experiment was to quantify the effects of unroasted or roasted ground-shelled corn (GSC), when fed with
alfalfa ensiled in bag, bunker, or O2
-limiting tower silos on ruminal digestion and microbial CP synthesis in lactating dairy cows.
The roasted corn was heat-treated in a propane-fired roasting system. Alfalfa was harvested as second cutting from fields with
regrowth of the same maturity. A portion of each field was allotted to each silo. The diets with 3 3 2 factorial arrangement of
treatments were fed to six multiparous rumen-cannulated Holstein cows in a cyclic change-over design with five 21-day periods.
Experimental diets were comparable and averaged (on dry matter (DM) basis): 410 g/kg alfalfa silage (AS), 150 g/kg corn silage,
350 g/kg GSC, 50 g/kg soybean meal, 40 g/kg roasted soybeans, 177 g/kg CP, 264 g/kg NDF and 250 g/kg starch. Nutrient flow was
quantified by the omasal sampling technique with use of three markers (Co, Yb and indigestible NDF). Continuous infusion of 10%
atom excess (

)2
SO4 was used to label microbial CP. None of the interactions between storage structure of dietary AS and
corn type were significant. DM intake was not different among dietary treatments, averaging 24.5 kg/day across diets. Means of
ADF digested in the rumen for cows fed diets with AS from bag, bunker and O2
-limiting tower silo were 2.1, 1.7 and 2.1 kg/day,
respectively, and was lower in cows fed AS from the bunker silo. This response may partly be a reflection of the higher intake
of ADF by cows fed AS ensiled in the O2
-limiting tower silo compared with the bunker. There was a slightly greater supply of
fermentable substrates for cows fed diets with roasted compared with unroasted GSC. The small increases in yield of milk protein
and lactose observed in the previous production trial in cows fed diets containing roasted corn may have occurred because of
greater supply of fermentable substrate
