The effect of macroeconomic variables on exchange rate: Evidence from Ghana
Cogent Economics & Finance, 2020 The study examined the effect of macroeconomic variables on exchange rate in Ghana using a multivariate modeling technique of the Vector Autoregression (VAR) and focusing on impact of broad money supply (M2), lending rate, inflation and real GDP on ...

Incommensurate Spiral Order from Double-Exchange Interactions [PDF]
Physical Review Letters, 2017 The double exchange model describing interactions of itinerant electrons with localized spins is usually used to explain ferromagnetism in metals. We show that for a variety of crystal lattices of different dimensionalities and for a wide range of model parameters the ferromagnetic state is unstable against a non-collinear spiral magnetic order.

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Macrospin dynamics in antiferromagnets triggered by sub-20 femtosecond injection of nanomagnons
Nature Communications, 2016 Magnetic order in nature is defined by the exchange interaction, however its understanding on the ultrafast- and nanometer-scales is limited. Here, the authors follow the femtosecond sub-nanometer dynamics of the antiferromagnetic order parameter in ...

Sacramental Exchange: Eschatological Economy and Consumption Ritual
Religions, 2020 Contemporary sacramental theology construes the sacraments as a symbolic gift exchange between God and humanity; God initiates in the ministry of Jesus Christ, and human beings acknowledge and respond to God’s gift.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

FEBS Letters, EarlyView.The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...
