Single antenna interference cancellation for synchronised GSM networks using a widely linear receiver

IET Communications, 2007
A novel cochannel single antenna interference cancellation (SAIC) receiver is proposed for synchronised Group Special Mobile (GSM) systems. The receiver uses a two-stage strategy, where in the first stage cochannel interference is cancelled by a widely linear filter, while inter-symbol interference due to the GSM frequency-selective Rayleigh-fading ...

Could the chemical industry mitigate rapid global cooling from a catastrophic volcanic eruption?

AIChE Journal, EarlyView.
Abstract Estimates based on historical data place the probability of a catastrophic volcanic eruption in the next 100 years at around one in six. Large volcanic eruptions can lead to significant global cooling for 2–4 years, with potentially devastating impacts on global agriculture.

The Architecture of Large Kurgans of the Scythians and Their Periphery: A Challenge for Magnetometer Prospections in the Eurasian Steppe Belt

Archaeological Prospection, EarlyView.
ABSTRACT The burial mounds of the early Iron Age, which we will refer to below as kurgans, from the nomadic equestrian warriors of Eurasia, form a very complex group of archaeological monuments. Archaeological excavations in Aržan 2 (Siberia) and Aleksandropol (Ukraine) show that the large burial mounds are complex architectural constructions.

Electronic and Magnetic Properties of Ferrous Iron in a True Square‐Planar Molecular Environment

Chemistry – A European Journal, Accepted Article.
The electronic and magnetic properties of ferrous iron in the substituted iron phthalocyanine, FePcOAr, exhibiting a true square‐planar molecular environment, are investigated. Inhibition of intermolecular interactions by steric substituents, allows detailed investigation of the electronic structure arising from the planar geometry of the d6 electron ...

Low‐Micromolar Quantification of Fluorinated Analytes Using Hyperpolarized 19F Benchtop Nuclear Magnetic Resonance

Chemistry–Methods, EarlyView.
Limits of detection and quantification of fluorinated analytes by 19F benchtop (1 T) NMR spectroscopy in the high nanomolar to low micromolar range are achieved using signal amplification by reversible exchange (SABRE) combined with the multiplet‐refocusing technique, SHARPER (Sensitive, Homogeneous, And Resolved PEaks in Real time).

Dielectrophoresis Tutorial: Inspired by Hatfield's 1924 Patent and Boltzmann's Theory and Experiments of 1874

ELECTROPHORESIS, EarlyView.
ABSTRACT The first patent to describe dielectrophoresis (DEP) as a means and process to separate particles from a mixture was granted by the US Patent Office to Henry Stafford Hatfield in 1924. The novel methods of sample preparation and designs of electrode geometry covered by the patent's disclosures and claims describe the basis for most present‐day

Exchange Rate Risk and Deviations From Purchasing Power Parity

International Journal of Finance &Economics, EarlyView.
ABSTRACT This paper proposes a new solution to the purchasing power parity (PPP) puzzles, arguing that investors' higher‐order risk attitudes, combined with higher‐order uncertainty about nominal exchange rates, as reflected by skewness and kurtosis, drive a risk premium that leads to deviations from PPP.
