Hamiltonian Loop Group Actions and T-Duality for group manifolds

, 2004
We carry out a Hamiltonian analysis of Poisson-Lie T-duality based on the loop geometry of the underlying phases spaces of the dual sigma and WZW models.

Comparing the Protests of Undocumented Migrants Beyond Contexts: Collective Actions as Acts of Emancipation [PDF]

, 2012
In this article, we demonstrate that the collective actions of undocumented migrants possess similar symbolic dimensions, even if the contexts of their actions differ.

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

“Netflix Wanted to Hold a Festival, and the Film World Tore Itself Apart.” Independence and Struggles at the Boundaries of a Cultural Industry

Biens Symboliques
In late 2021, the proposed programming of the Netflix Film Club—a festival showcasing Netflix original productions—in some of France’s most renowned arthouse cinemas, sparked fierce controversy. The polemic revealed a united front among film distribution

Monopole Condensation and Antisymmetric Tensor Fields: Compact QED and the Wilsonian RG Flow in Yang-Mills Theories [PDF]

, 1999
A field theoretic description of monopole condensation in strongly coupled gauge theories is given by actions involving antisymmetric tensors B_{\mu\nu} of rank 2.

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Analysis of perceptions and knowledge in managing coastal resources: A case study in Fiji

Frontiers in Marine Science, 2016
Sustainable management of coastal resources depends on human knowledge and perceptions of natural resources and coastal environments. However, empirical evidence has been limited in order to understand linkages between knowledge, perceptions and ...

Collaborative and collective! Reflexive coordination and the dynamics of open innovation in clusters [PDF]

Economic geography increasingly conceptualises "innovation as a collective action" (Storper, 1996). However, cluster literature often reduces the collective dimension to the circulation of knowledge between local-regional organisations based on various ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
