Pre‐industrial Use of Bauxite by Late Gothic Goldsmith Masters: Analytical Evidence and Experimental Study

open access: yesChemPlusChem, EarlyView.
First analytical evidence and replication of yet undescribed substantial change in gilding technology in the early modern period ‐ the replacement of imported red clay (bole) with locally available bauxite. Proof of its source ‐ Croatian Minjera, according to a unique find of mineral diaspore.

Current‐Mirror Based Filters With Reduced Circuit Complexity

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A novel current‐mirror‐based lossless integration stage, derived from the corresponding lossy integration stage, just by adding an extra DC current source, is introduced in this letter. The unique contribution that it offers is the reduction of the circuit complexity in the resulting current‐mode systems, where the introduced integrator is utilized.

The effects of climate on bat morphology across space and time

open access: yesEcography, EarlyView.
According to Bergmann's and Allen's rules, climate change may drive morphological shifts in species, affecting body size and appendage length. These rules predict that species in colder climates tend to be larger and have shorter appendages to improve thermoregulation. Bats are thought to be sensitive to climate and are therefore expected to respond to

From One Strand Dyed/Undyed Hair With/Without Root to Fast and Successful STR Profiling and Evaluation With Principle Component Analysis

open access: yesELECTROPHORESIS, EarlyView.
ABSTRACT Fallen/shed single hair shafts with/without roots can be encountered as evidence in crime scenes. Identification from hair exhibits serious difficulties, due to the low amount of DNA, PCR inhibitors, and the existence of DNA mostly in degraded forms. Exposure of hair to chemical oxidation, sunlight, etc.

(Im)mobile intimacies: Commodities and marriage at the crossroads of Asia

open access: yesFeminist Anthropology, EarlyView.
Abstract This article follows traders and entrepreneurs that live and work between Kyrgyzstan and China's northwestern region of Xinjiang. Looking specifically at Islamic marriage and business partnerships forged between persecuted Uyghurs and their Uzbek partners, it argues that commodity‐mediated forms of transnational intimacy create spaces of ...
