A new class of group field theories for 1st order discrete quantum gravity [PDF]
, 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.

On the pitfalls of Airy isostasy and the isostatic gravity anomaly in general [PDF]
, 2019 Isostatic gravity anomalies provide a measure of the Earth's gravity field free from the gravitational attractions of the topography and its isostatic compensation, most commonly represented by a variation in the depth of a compensating density contrast,

Anomaly-free scale symmetry and gravity
, 2023 In this Letter, we address the question of whether the conformal invariance can be considered as a global symmetry of a theory of fundamental interactions.

The emergence of spacetime, or, quantum gravity on your desktop [PDF]
, 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

A locally finite model for gravity [PDF]
, 2008 Matter interacting classically with gravity in 3+1 dimensions usually gives rise to a continuum of degrees of freedom, so that, in any attempt to quantize the theory, ultraviolet divergences are nearly inevitable.

Paediatric development of radiopharmaceutical imaging agents and radioligand therapeutics
British Journal of Clinical Pharmacology, EarlyView.Abstract This review focuses on the development of radiopharmaceutical imaging agents and radioligand therapeutics for paediatric use. Nuclear medicine plays an important role in the diagnosis and treatment of various childhood conditions, including cancers, infections and brain disorders.

Using satellite altimetry leveling to assess the marine geoid
Geodesy and Geodynamics, 2020 Based on the concept of Global Position System (GPS)/leveling, the satellite altimetry leveling (SAL) is first proposed to evaluate the marine geoid. SAL is derived by the difference among the mean sea surface (MSS), mean dynamic ocean topography (MDT ...

Heterotic Braneworld Gravity [PDF]
, 2009 In the past decade, there has been considerable interest in braneworld scenarios where the universe lives on a brane in a higher-dimensional bulk and gravity is modified.
