Compatibility of personal care thickening polymers in sulphate‐free surfactants

International Journal of Cosmetic Science, EarlyView.
Phase behaviour for alpha olefin sulfonate surfactant 10–15 wt% combined with 1 wt% sodium carboxy methyl cellulose, clearly indicating the sensitivity in miscibility when adding various levels of background salt. Abstract Objective Formulators today know that when traditional surfactants and polymers are replaced new problems occur. What was before a ‘

A physiologically relevant in vitro screening model for predictive assessment of foundation colour shift

International Journal of Cosmetic Science, EarlyView.
A novel airbrush‐based in vitro sebum secretion model enables predictive assessment of foundation colour shift. Artificial sebum was applied at a physiologically relevant amount and 3 h post‐foundation application. Our results showed strong alignment with consumer perception and revealed the dominance of drying‐phase dynamics in foundation colour shift.

Miners' Reward Elasticity and Stability of Competing Proof‐of‐Work Cryptocurrencies

International Economic Review, EarlyView.
ABSTRACT Proof‐of‐Work cryptocurrencies employ miners to sustain the system through algorithmic reward adjustments. We develop a stochastic model of the multicurrency mining and identify conditions for stable transaction speeds. Bitcoin's algorithm requires hash supply elasticity <$<$1 for stability, while ASERT remains stable for any elasticity and ...

Longitudinal associations between violence exposure and adolescent conduct problems in a high‐adversity, South African setting

Journal of Child Psychology and Psychiatry, EarlyView.
Background Violence exposure is a well‐established risk factor for adolescent conduct problems, yet longitudinal research in high‐adversity, low‐ and middle‐income countries (LMICs) remains limited. This study investigated whether early adolescent violence exposure predicts concurrent and longer‐term conduct problems, and explored potential ...
