Quantum Gravity: Has Spacetime Quantum Properties? [PDF]
, 2009 The conceptual incompatibility between General Relativity and Quantum Mechanics is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - Quantum Mechanics gives a universally valid

Advanced Functional Materials, EarlyView.We introduce a capillary‐filtering‐based particle‐filling (CFPF) process that simultaneously forms vertical thermal pathways and electrical vias within µ‐pores. In situ microfluidic analysis reveals that capillary‐driven velocity gradients generate vorticity that governs µ‐platelet rotation and vertical alignment.

A new class of group field theories for 1st order discrete quantum gravity
, 2008 Group Field Theories, a generalization of matrix models for 2d gravity, represent a 2nd quantization of both loop quantum gravity and simplicial quantum gravity.

Advanced Functional Materials, EarlyView.An architecture‐enabled bottom‐heated 3D solar convective evaporator spatially decouples photothermal heating from evaporation, triggering natural convection that intensifies sidewall vapour removal and heat transfer. The system achieves significantly enhanced evaporation rates over 2D and conventional 3D designs while confining salt precipitation to ...

Analytical kernels for efficient constant Q transforms in dark matter searches with LIGO
Scientific ReportsWe introduce a novel scalable logarithmic spectral estimation method based on insights from computer-music analysis, allowing us to perform an efficient constant Q transform with no need for pre-computing.

The emergence of spacetime, or, quantum gravity on your desktop
, 2008 Is there an approach to quantum gravity which is conceptually simple, relies on very few fundamental physical principles and ingredients, emphasizes geometric (as opposed to algebraic) properties, comes with a definite numerical approximation scheme, and

Reduced Graphene Oxide Transparent Electrodes Enabling Compact Soft Tunable Lenses
Advanced Functional Materials, EarlyView.By spray‐coating an elastomeric membrane with reduced graphene oxide (rGO) at various surface densities, elastomeric actuators are manufactured. Electro‐mechano‐optical characterizations show the suitability of rGO as an effective material for compliant, semi‐transparent electrodes, enabling soft electrically tunable lenses with a compact form factor ...

International trade without CES : estimating translog gravity [PDF]
, 2010 This paper derives a micro-founded gravity equation in general equilibrium based on a translog demand system that allows for endogenous markups and substitution patterns across goods. In contrast to standard CES-based gravity equations, trade is more
