Topological open/closed string dualities: matrix models and wave functions
We sharpen the duality between open and closed topological string partition functions for topological gravity coupled to matter. The closed string partition function is a generalized Kontsevich matrix model in the large dimension limit.

This study investigates the role of triply periodic minimal structures in load bearing bone tissue engineering applications. Research uses a combination of mechanical testing, material characterization, and in vitro tests to study the impact of TPMS lattice structures (gyroid, lidinoid and split‐P).

T-Duality in the Green-Schwarz Formalism, and the Massless/Massive IIA Duality Map [PDF]
We derive a component-field expansion of the Green-Schwarz action for the type IIA string, in an arbitrary background of massless NS-NS and R-R bosonic fields, up to quadratic order in the fermionic coordinates \theta.

Open/closed string duality for topological gravity with matter [PDF]
The exact FZZT brane partition function for topological gravity with matter is computed using the dual two-matrix model. We show how the effective theory of open strings on a stack of FZZT branes is described by the generalized Kontsevich matrix integral,

A 3D‐printed PCL scaffold coated with Arginine was laminated with electrospun polyvinyl alcohol (PVA) nanofibers containing cationic cellulose nanocrystals (PVA@cCNC). This created nanoisland‐like regions of aligned and random cCNC‐rich fibers. The composite scaffold, under fluid shear stimulation, modulated macrophage polarization from M1 to M2 ...

We detail the construction of the exceptional sigma model, which describes a string propagating in the “extended spacetime” of exceptional field theory. This is to U-duality as the doubled sigma model is to T-duality. Symmetry specifies the Weylinvariant

Extracellular vesicles (EVs) are pivotal mediators of intercellular communication and disease, yet the fundamental mechanisms controlling their biogenesis and cargo selection remain unclear. This limitation hinders their diagnostic utility and therapeutic development.

Gauge/gravity correspondence from open/closed string duality [PDF]
We compute the annulus diagram corresponding to the interaction of a fractional D3 brane with a gauge field on its world-volume and a stack of N fractional D3 branes on the orbifolds 2/2 and 3/(2 ? 2).

Gauge spinors and string duality [PDF]
When the gauge groups of the two heterotic string theories are broken, over tori, to their "SO(16)x SO(16)" subgroups, the winding modes correspond to representations which are spinorial with respect to those subgroups. Globally, the two subgroups are isomorphic neither to SO(16)x SO(16) nor to each other.

A mechanically active OsteoChondral Unit (OCU)‐on‐Chip platform mimicking the OCU's functional anatomy and the strain gradient across the osteochondral interface is presented. Upon compartment‐specific hyperphysiological compression, the model replicates mechanisms observed in osteoarthritis (OA) progression, such as calcium crystal accumulation ...
