A solvable model of flat space holography
We propose an explicit realization of flat space holography in two dimensions where both sides of the duality are independently defined and the boundary theory is completely solvable.

Comparison of therapeutic and diagnostic applications of a surface‐emitting light source with multiwavelength emission characteristics. Abstract Conventional light‐emitting‐diode‐based light sources suffer from rigidity, localized heating, and poor adaptability to skin deformation, limiting their use in skin‐attached medical devices.

Spikes and spines in 4D Lorentzian simplicial quantum gravity
Simplicial approaches to quantum gravity such as quantum Regge calculus and spin foams include configurations where bulk edges can become arbitrarily large while the boundary edges are kept small.

This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

What is the curvature of 2D Euclidean quantum gravity?
We re-examine the nonperturbative curvature properties of two-dimensional Euclidean quantum gravity, obtained as the scaling limit of a path integral over dynamical triangulations of a two-sphere, which lies in the same universality class as Liouville ...

Off-shell unimodular N = 1, d = 4 supergravity
We formulate a unimodular N = 1, d = 4 supergravity theory off shell. We see that the infinitesimal Grassmann parameters defining the unimodular supergravity trans- formations are constrained and show that the conmutator of two infinitesinal unimodular ...

Aqueously Upcycled Lignin with Emergent Tribonegativity for Skin‐Integrated Triboelectronics
Aqueously upcycled lignin is transformed into a printable ink that self‐assembles into a nanotextured surface during printing with the highest reported biopolymer‐based tribonegativity. The resulting skin‐integrated triboelectric sensor enables high‐fidelity cardiovascular monitoring and objective mental workload classification, demonstrating a ...

Influence of Micropillar Height Modulation on Droplet Evaporation and Wetting State Transitions
Controlling droplet evaporation dynamics is crucial across many fields. Here, it demonstrates laser‐fabricated polymer micropillar arrays with tailored height variations to regulate evaporation behavior. While all arrays exhibit superhydrophobic wetting, their distinct height profiles effectively slow evaporation and alter evaporation modes ...

A model of quantum gravity with emergent spacetime [PDF]
Abstract We construct a model of quantum gravity in which dimension, topology and geometry of spacetime are dynamical. The microscopic degree of freedom is a real rectangular matrix whose rows label internal flavours, and columns label spatial sites. In the limit that the size of the matrix is large, the sites can collectively form
