Towards A Topological G_2 String
, 2005 We define new topological theories related to sigma models whose target space is a 7 dimensional manifold of G_2 holonomy. We show how to define the topological twist and identify the BRST operator and the physical states. Correlation functions at genus zero are computed and related to Hitchin's topological action for three-forms.

Small, EarlyView.This work identifies a size‐dependent shrinkage effect that arises during polymer pyrolysis and uses it to embed residual stress into tensegrity‐inspired nanoarchitectures. By adjusting the dimensions of the structural elements, controlled prestress can be introduced in a simple and repeatable manner, enabling mechanically tunable nanostructures with ...

Mind and Cosmos as Throughput Systems: A Convergence Through the Throughput Model
Systems Research and Behavioral Science, EarlyView.ABSTRACT This paper advances a conceptual and mathematical foundations approach by applying the throughput model (TPM) to cosmic phenomena, reframing the universe as an extended information processing system. TPM's four stages, Perception, Information, Judgement and Decision Choice, are reformulated in explicit information‐theoretic and dynamical ...

Bound by blood and bloodshed: Sibling ties and participation in genocidal violence
Criminology, EarlyView.Abstract Focusing on the 1994 genocide in Rwanda, we examine how sibling relationships—one of the most salient familial bonds—influence individual engagement in violence during mass atrocity. Drawing on an adaptation of differential association and social learning theories for contexts of mass atrocity, we analyze a novel dataset linking over 300,000 ...

Integrative Zoology, EarlyView.Kaempferol modulates the tryptophan metabolism pathway by increasing the abundances of Christensenellaceae R7 group, Bacteroides, and Blautia and reducing that of Rikenellaceae RC9 gut group, thereby significantly increasing the levels of ILA and IAA. This process inhibits the activation of NF‐κB/NLRP3 signaling pathway, reduces pro‐inflammatory factor

Allergy, EarlyView.We exposed human nasal epithelial tissues to pollen from grasses grown under different climate treatments (temperature and CO2). Pollen weakened epithelial tight junctions and altered cytokine‐related gene expression, with similar protein‐level effects.

Homo luzonensis and the role of homoplasy in the morphology of hominin insular species
Cladistics, EarlyView.Abstract Homo luzonensis lived during the upper Pleistocene in the northern Philippines, east of the Wallace line. The few specimens attributed to this species show a mosaic of plesiomorphies for the genus Homo and apomorphies found in upper Pleistocene Homo species.

The ALE partition functions of M-strings
Journal of High Energy PhysicsWe compute the equivariant partition function of the six-dimensional M-string SCFTs on a background with the topology of a product of a two-dimensional torus and an ALE singularity.
