Rethinking Representation: Representative Claims in Global Perspective

Politics and Governance, 2019
The established notion of political representation is challenged on multiple accounts—theoretically, conceptually, and empirically. The contributions to this thematic issue explore the constructivist turn as the means for rethinking political ...

On the Hyperbolic Gluing Equations and Representations of Fundamental Groups of Closed 3-Manifolds [PDF]

arXiv, 2010
We show that for a representation of the fundamental group of a triangulated closed 3-manifold (not necessarily hyperbolic) into $\PSL$ so that any edge loop has non-trivial image under the representation, there exist uncountably many solutions to the hyperbolic gluing equation whose associated representations are conjugate to the given representation,

Diphthamide synthesis is linked to the eEF2‐client chaperone machinery

FEBS Letters, EarlyView.
The diphthamide modification of eukaryotic translation elongation factor 2 (eEF2) is important for accurate protein synthesis. We addressed the potential coordination of de novo eEF2 synthesis with simultaneous or subsequent diphthamide modification. Our work reveals that the co‐chaperones Hgh1 and Cpr7, which are known to support folding of nascent ...

The Equivariant Fundamental Groupoid as an Orbifold Invariant [PDF]

arXiv, 2019
We construct a 2-category version of tom Dieck's equivariant fundamental groupoid for representable orbifolds and show that the discrete fundamental groupoid is Morita invariant; hence an orbifold invariant for representable orbifolds.

Characterization of fungal carbonyl sulfide hydrolase belonging to clade D β‐carbonic anhydrase

FEBS Letters, EarlyView.
Here, we performed a functional analysis of the fungal enzymes belonging to clade D of the β‐class carbonic anhydrase family (β‐D‐CA). The β‐D‐CAs in the basidiomycete Gloeophyllum trabeum and the ascomycete Trichoderma harzianum showed very low activity in the hydration of CO2 but exhibited high activity in the hydrolysis of carbonyl sulfide (COS ...

Representations of Gelfand-Graev type for the unitriangular group [PDF]

Fundamental and applied mathematics, 18:3, 2013, 161-178, 2014
We consider the analog of Gelfand-Graev representations of the uniteriangular group. We obtain the decomposition into the sum of irreducible representations, prove that these representations are multiplicity free, calculate the Hecke algebra.}

Automatic Analysis of Facial Affect: A Survey of Registration, Representation, and Recognition

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2015
Automatic affect analysis has attracted great interest in various contexts including the recognition of action units and basic or non-basic emotions.

Elucidation of interface interactions between a dehydratase domain and an acyl carrier protein in cremimycin polyketide synthase

FEBS Letters, EarlyView.
In modular polyketide synthases, the dehydratase (DH) domain catalyzes the dehydration reaction of the β‐hydroxyacyl unit attached to the cognate acyl carrier protein (ACP) domain. However, it is unclear how DH interacts with ACP during the reaction. In this study, we identified DH–ACP interface residues, providing the first detailed insights into DH ...

Some remarks on the companions conjecture for normal varieties

Comptes Rendus. Mathématique
Drinfeld in 2010 proved the companions conjecture for smooth varieties over a finite field, generalizing L. Lafforgue’s result for smooth curves. We study the obstruction to prove the conjecture for arbitrary normal varieties.

Branching rules for modular fundamental representations of symplectic groups [PDF]

arXiv, 2000
In this paper branching rules for the fundamental representations of the symplectic groups in positive characteristic are found. The submodule structure of the restrictions of the fundamental modules for the group $Sp_{2n}(K)$ to the naturally embedded subgroup $Sp_{2n-2}(K)$ is determined.
