Tradeoffs in automated financial regulation of decentralized finance due to limits on mutable turing machines.

We examine which decentralized finance architectures enable meaningful regulation by combining financial and computational theory. We show via deduction that a decentralized and permissionless Turing-complete system cannot provably comply with regulations concerning anti-money laundering, know-your-client obligations, some securities restrictions and forms of exchange control. Any system that claims to follow regulations must choose either a form of permission or a less-than-Turing-complete update facility.

Introduction: Financial stress (FS) during young adulthood may have lasting effects on financial security, physical health, and overall wellbeing. This study examines the burden, social determinants and mental health consequences of experienced FS among young adults in the United States, based on objective measures of financial stress.
Methods: We studied young adults aged 18-26 years using pooled data from the 2013-18 National Health Interview Survey.
Navigating DR-TB Treatment care: a qualitative exploration of barriers and facilitators to retention in care among people with history of early disengagement from drug-resistant tuberculosis treatment in Johannesburg, South Africa.

Background: Despite advances in drug-resistant tuberculosis (DR-TB) diagnosis, treatment, and service delivery, individuals with DR-TB often face significant socioeconomic and psychosocial challenges due to limited resources. These challenges can hinder retention in care, undermining the progress made in DR-TB management. As a consequence, advances in DR-TB diagnostics and treatment have not resulted in DR-TB programs meeting the 75% treatment success targets set by the World Health Organization (WHO).

Promises are widely used to increase trust in social status; yet how promise levels and social status influence trust behavior and its underlying neurophysiological mechanisms remain unclear. We used a modified trust game to investigate the effects of promise levels and social status on trust behavior. Participants, as investors paired with trustees of varying social status who were given the opportunity to promise to return different levels of money, were required to decide to whether trust the trustees.

Ranking sectors and countries within global value chains is of paramount importance to estimate risks and forecast growth in large economies. However, this task is often non-trivial due to the lack of complete and accurate information on the flows of money and goods between sectors and countries, which are encoded in input-output (I-O) tables. In this work, we show that an accurate estimation of the role played by sectors and countries in supply chain networks can be achieved without full knowledge of the I-O tables, but only relying on local and aggregate information, e.
