Comparison of differential representations for radially symmetric Stokes flow
Abstract and Applied Analysis, 2004 Papkovich and Neuber (PN), and Palaniappan, Nigam, Amaranath, and Usha (PNAU) proposed two different representations of the velocity and the pressure fields in Stokes flow, in terms of harmonic and biharmonic functions, which form a practical tool for ...

Comparative evaluation of interpolation methods for the directivity of musical instruments
EURASIP Journal on Audio, Speech, and Music Processing, 2021 Measurements of the directivity of acoustic sound sources must be interpolated in almost all cases, either for spatial upsampling to higher resolution representations of the data, for spatial resampling to another sampling grid, or for use in simulations

Spherical subcategories in representation theory [PDF]
Mathematische Zeitschrift, 2018 We introduce a new invariant for triangulated categories: the poset of spherical subcategories ordered by inclusion. This yields several numerical invariants, like the cardinality and the height of the poset. We explicitly describe spherical subcategories and their poset structure for derived categories of certain finite-dimensional algebras.

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Representations, Characters, and Spherical Functions Associated to Causal Symmetric Spaces
, 1999 In this paper we study spherical unitary highest weight representations associated to a compactly causal symmetric space and use the results to prove estimates for the corresponding spherical functions of the c-dual non-compactly causal symmetric space ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Complete Irreducibility and X-Spherical Representations
Journal of Functional Analysis, 1993 Let \(G\) be a locally compact group, \(K\) a compact subgroup and \(\chi:K \to \{| z |=1\}\) be a continuous homomorphism. Let \(\pi\) be a continuous representation of \(G\) on a complete locally convex space \(V\) such that the subspace \(V(\chi)=\{v \in V \mid \pi(k) v=\chi(k)v,\;k \in K\}\) is one-dimensional. The author shows that \(\pi\) is then

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

A characterization of spherical series representations of the free group
, 1991 The spherical series representations of a free nonabelian group are here characterized as those irreducible unitary representations possessing a certain type of matrix coefficient.
