Meteoritics &Planetary Science, EarlyView.Abstract Despite meteorites having been recognized as the source of iron in some ancient iron artifacts, few archeological irons have been analyzed so far, as invasive methods are precluded. In this work, four iron knives and one axe collected near Guelmime and Imilchil (Morocco) were investigated by advanced analytical techniques, including handheld ...

Chondrule size averaging in two and three dimensions
Meteoritics &Planetary Science, EarlyView.Abstract Chondrule sizes are an important discriminant of chondrite groups and chondrule formation theories. Yet most studies report 2‐D sizes without attempting the somewhat tedious corrections to 3‐D proposed in the past literature. I show here that 3‐D size averages can be simply calculated directly from 2‐D averages of appropriate powers of sizes ...

Problems with the cosmological constant problem [PDF]
, 2017 The cosmological constant problem is widely viewed as an important barrier and hint to merging quantum field theory and general relativity. It is a barrier insofar as it remains unsolved, and a solution may hint at a fuller theory of quantum gravity.

A Self-Tuning Solution of the Cosmological Constant Problem [PDF]
, 2000 We discuss the four-dimensional cosmological constant problem in a five-dimensional setting. A scalar field coupled to the SM forms dynamically a smooth brane with four-dimensional Poincar\'e invariance, independently of SM physics.

Extracting vitalities: Cuts in Indigenous women's bodies‐territories (Brazil)
Medical Anthropology Quarterly, EarlyView.Abstract In this article, I explore the connections between the medicalization of childbirth and environmental devastation through Guarani‐Mbyá understandings of life and the living. I argue that the cuts made to Guarani‐Mbyá women's vaginas (episiotomies) in Brazilian hospitals are experienced and situated on the same cosmopolitical level as the cuts ...

Can compactifications solve the cosmological constant problem?
, 2017 Recently, there have been claims in the literature that the cosmological constant problem can be dynamically solved by specific compactifications of gravity from higher-dimensional toy models.

Landscaping the strong CP problem
Journal of High Energy Physics, 2019 One often hears that the strong CP problem is the one problem which cannot be solved by anthropic reasoning. We argue that this is not so. Due to nonperturbative dynamics, states with a different CP violating paramenter θ acquire different vacuum ...

, 2003 The cosmological constant problem is reviewed and a possible quantum gravity resolution is proposed. A space satellite Eötvös experiment for zero-point vacuum energy is proposed to see whether Casimir vacuum energy falls in a gravitational field at the same rate as ordinary matter.

The Analogia Entis for Reformed Theology: Retrieving Calvin's Implicit Metaphysics
Modern Theology, EarlyView.Abstract The famous controversy between Emil Brunner and Karl Barth which led to Barth's ‘No!’ was driven by disagreements over how to read John Calvin: Barth and Brunner never agreed on whether Calvin had a doctrine of the analogy of being. This article rekindles the debate.
