Reverse engineering of ceramic anthropomorphic figurines from the Tumaco archaeological tradition in southwest Colombia.
Traditional studies of archaeological ceramics in Colombia have been largely based on visual and stylistic analyses. Here we introduce frameworks and concepts of reverse engineering as a complementary strategy to develop...

Testing the New World
Abstract: The paper presents new research on an assemblage of metallurgical crucibles used in the assay of minerals at colonial Jamestown. The aim of the study is to explore the range of chemical operations carried out at the...
Amber in prehistoric Iberia
Mercedes Murillo-Barroso, Enrique Peñalver, Primitiva Bueno, Rosa Barroso, Rodrigo de Balbín, Marcos Martinón-Torres
Nov 13, 2018
Provenancing exotic raw materials and reconstructing the nature and routes of exchange is a major concern of prehistoric archaeology. Amber has long been recognised as a key commodity of prehistoric exchange networks in Europe....
Interwoven traditions in Bell Beaker metallurgy

Sep 13, 2021
Debates on early metallurgy in Western Europe have frequently focused on the social value of copper (between utilitarian and symbolic) and its purported role in the emergence and consolidation of hierarchies. Recent research...
A Comparative Analysis of Deep Learning Approaches for Network Intrusion Detection Systems (N-IDSs)
Recently, due to the advance and impressive results of deep learning techniques in the fields of image recognition, natural language processing and speech recognition for various long-standing artificial intelligence (AI) tasks...

The neural basis of hot and cold cognition in depressed patients, unaffected relatives, and low-risk healthy controls
BACKGROUND: Modern cognitive neuropsychological models of depression posit that negatively biased emotional ("hot") processing confers risk for depression, while preserved executive function ("cold") cognition promotes...
Non-Lorentzian SU(1, n) Spacetime Symmetry In Various Dimensions
We discuss non-Lorentzian Lagrangian field theories in $2n-1$ dimensions that
admit an $SU(1,n)$ spacetime symmetry which includes a scaling transformation.
These can be obtained by a conformal compactification of a...
Exact properties of an integrated correlator in N = 4 SU( N ) SYM
Abstract: We present a novel expression for an integrated correlation function of four superconformal primaries in SU(N) N = 4 supersymmetric Yang-Mills (N = 4 SYM) theory. This integrated correlator, which is based on...
Factorisation of 3d N = 4 twisted indices and the geometry of vortex moduli space
We study the twisted indices of $\mathcal{N}=4$ supersymmetric gauge theories
in three dimensions on spatial $S^{2}$ with an angular momentum refinement. We
demonstrate factorisation of the index into holomorphic blocks for...

Voltammetric Monitoring of a Solid-Liquid Phase Transition in N,N,N’,N’-Tetraoctyl-2,6-diamino-9,10-anthraquinone (TODAQ)
Sun Yhik Ahn, Thomas Forder, Matthew Jones, Richard Blackburn, Paul Fordred, Steven Bull, Frank Marken
Jan 31, 2020
Exploratory experiments on effects from a phase transition are reported for a low-melting microcrystalline anthraquinone (N,N,N′,N′-tetraoctyl-2,6-diamino-9,10-anthraquinone or TODAQ). Data for the solid-liquid phase...

On the appearance of nitrite anion in [PdX(OAc)L<sub>2</sub>] and [Pd(X)(C∧N)L] syntheses (X = OAc or NO<sub>2</sub>)

Pd 3(OAc) 5NO 2, an impurity in "Pd(OAc) 2" {formally Pd 3(OAc) 6}, emerges as a serious issue in the synthesis of pure Pd II complexes derived from Pd(OAc) 2, for example in our C-H activation precatalyst, Pd(OAc) 2(pip) 2 (pip...
Surface chromium on Terracotta Army bronze weapons is neither an ancient anti-rust treatment nor the reason for their good preservation.

For forty years, there has been a widely held belief that over 2,000 years ago the Chinese Qin developed an advanced chromate conversion coating technology (CCC) to prevent metal corrosion. This belief was based on the detection...
