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 ...

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Exchange rate regimes and external financial stability [PDF]
Ekonomski Anali, 2016 Financial stability within the framework of the global financial crisis has become a common topic for researchers and practitioners. In order to analyse the impact of exchange rate regimes on financial stability we use both the de jure and de ...

Social Exchange and Micro Social Order [PDF]
American Sociological Review, 2008 This study uses an affect theory of social exchange (Lawler 2001) to investigate how and when network structures generate “micro social orders.” Micro social order entails recurrent interactions, emotional reactions, perceptions of a group, and affective sentiments.

A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner
Molecular Oncology, EarlyView.We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

The examination of signaling theory versus pecking order theory: Evidence from Tehran Stock Exchange [PDF]
Management Science Letters, 2013 This study investigates the explanatory power of leverage and cash flows in future cash flow prediction in Tehran Stock Exchange by considering Signaling Theory and Pecking Order Theory. Based on theoretical foundations, the regression models of leverage

Competing Spin Liquids and Hidden Spin-Nematic Order in Spin Ice with Frustrated Transverse Exchange
Physical Review X, 2017 Frustration in magnetic interactions can give rise to disordered ground states with subtle and beautiful properties. The spin ices Ho_{2}Ti_{2}O_{7} and Dy_{2}Ti_{2}O_{7} exemplify this phenomenon, displaying a classical spin-liquid state, with ...

Protein O‐glycosylation in the Bacteroidota phylum
FEBS Open Bio, EarlyView.Species of the Bacteroidota phylum exhibit a unique O‐glycosylation system. It modifies noncytoplasmic proteins on a specific amino acid motif with a shared glycan core but a species‐specific outer glycan. A locus of multiple glycosyltransferases responsible for the synthesis of the outer glycan has been identified.

Order from disorder in the double-exchange model [PDF]
Journal of Physics: Condensed Matter, 2002 The magnetic excitations of the double exchange (DE) model are usually discussed in terms of an equivalent ferromagnetic Heisenberg model. However this equivalence is valid only at a quasi--classical level - we show that both quantum and thermal corrections to the magnetic properties of DE model differ from an effective Heisenberg model because its ...
