It has been observed that the low temperature magnetoresistance behaviour in polycrystalline colossal magnetoresistive (CMR) manganites differ significantly from the single crystals. The polycrystalline samples show large magnetoresistance at temperatures much below the ferromagnetic transition temperature where the magnetoresistance of single crystals is very small. This has conventionally bee...

The ENVISAT ASAR (Advanced Synthetic Aperture Radar) AP (Alternating Polarisation) mode provides a new opportunity for spaceborne monitoring of vessel traffic and fishing activities. A series of data has been collected and analysed over Canadian and Norwegian waters, as well as other locations of opportunity. Three vessels were imaged during a Canadian trial and an oil production vessel in the ...

We investigate the Tits buildings of the paramodular groups with or without canonical level structure, respectively. These give important combinatorical information about the boundary of the toroidal compactification of the moduli spaces of non-principally polarised Abelian varieties. We give a full classification of the isotropic lines for all of these groups. Furthermore, for square-free, cop...

In this work we study the reflection of circularly polarised light from a nano-structured biological material found in the exocuticle of scarabus beetles. This material is made of a stack of ultra-thin (~5 nm) uniaxial layers arranged in a left-handed helicoidal stack, which resonantly reflects circularly polarized light. A chirp in the layer thickness combined with a finite absorption coeffici...

The HERMES experiment at DESY, Hamburg used the HERA 27.6GeV electron/positron polarised beam to study the structure of the nucleon. Deeply Virtual Compton Scattering (DVCS) provides access to Generalised Parton Distributions (GPDs) via measured azimuthal asymmetries. Data was collected from 1995 to 2007 with both longitudinally and transversely polarised gas tar-gets(H, D or heavier nuclei), w...

This paper presents a conical monopole antenna with two C-shaped slots to provide a frequency stopband to suppress interference. Compared to previous work reported in the literature, the antenna provides increased gain suppression to vertically polarised signals within the notch-band of up to 41.5 dB in four specific directions. It also yields omni-directional radiation patterns at frequencies ...

We report a new measurement of the beam-spin asymmetry $\boldsymbol{\Sigma}$ for $\vec{\gamma} n \rightarrow K^+\Sigma^-$ reaction using quasi-free neutrons in liquid-deuterium target. The dataset includes data at previously unmeasured photon energy and angular ranges, thereby providing constraints on partial wave analyses used to extract properties excited nucleon states. experimental were obt...
