An approach to anomalies in M-theory via KSpin
, 2007 The M-theory fieldstrength and its dual, given by the integral lift of the left hand side of the equation of motion, both satisfy certain cohomological properties.

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 degree theory for a class of perturbed Fredholm maps
Fixed Point Theory and Applications, 2005 We define a notion of degree for a class of perturbations of nonlinear Fredholm maps of index zero between infinite-dimensional real Banach spaces. Our notion extends the degree introduced by Nussbaum for locally α-contractive perturbations of the ...

Orientability of Fredholm families and topological degree [PDF]
, 1994 We construct a degree theory for oriented Fredholm mappings of index zero between open subsets of Banach spaces and between Banach manifolds. Our approach is based on the orientation of Fredholm mappings: it does not use Fredholm structures on the domain

Streamlined subrecursive degree theory
Annals of Pure and Applied Logic, 2012 The paper under review consists of two parts. Part I is devoted to the investigation of the structure of honest elementary degrees, i.e., the degree structure induced on the honest functions by the reducibility relation ``being (Kalmar) elementary in''. In Part II the degree theory found in Part I is generalized.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Conceptualizing degrees of theory of mind [PDF]
Proceedings of the National Academy of Sciences, 2018 Successful navigation of the social world requires making accurate inferences about the contents of other people’s minds, being able to represent in one’s own mind the thoughts, beliefs, and intentions of another. This “theory of mind” (ToM) ability allows us to explain and predict others’ behavior in terms of their mental states (1).

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

FEBS Letters, EarlyView.Mitochondrial remodeling shapes neural and glial lineage progression by matching metabolic supply with demand. Elevated OXPHOS supports differentiation and myelin formation, while myelin compaction lowers mitochondrial dependence, revealing mitochondria as key drivers of developmental energy adaptation.

Variational inequalities with the duality operator in Banach spaces
Results in Nonlinear Analysis, 2020 We study variational inequality by way of metric projection in Banach spaces. The main method is to use a topological degree theory for the class of operators of monotone type in Banach spaces. More precisely, some variational inequality associated with
