Tunable p–p Interactions Along Linear Chains Control Metavalent Bonding in Chalcogenide Heterostructures

open access: yesAdvanced Science, EarlyView.
Substitution of Sr at the Pb site within an atomic plane of PbTe perturbs the p–p hopping network. Since Sr does not support the p–p interaction key to metavalent bonding along (‐Pb‐Te‐) chains, long‐range electronic charge transfer in response to displacement of Pb is stalked at the Sr site.

Studying Transaction Fees in the Bitcoin Blockchain with Probabilistic Logic Programming

open access: yesInformation, 2019
In Bitcoin, if a miner is able to solve a computationally hard problem called proof of work, it will receive an amount of bitcoin as a reward which is the sum of the fees for the transactions included in a block plus an amount inversely proportional to ...

AARS1‐Mediated RUNX3 K193 Lactylation Enhances the Activation and Cytotoxicity of CD8+T Cells in Smoking‐Related Emphysema

open access: yesAdvanced Science, EarlyView.
Exposure to CS causes an elevation of AARS1 levels, which increases the levels of RUNX3 lactylation at the K193 site and increases protein levels of RUNX3 through inhibition of autolysosomal degradation. Elevated RUNX3 levels promote CD8+T cell activation and augment their cytotoxicity, which induces alveolar epithelial cell death and facilitates the ...

MetaboSense: An Integrated Quantum Dot‐Mediated Aptamer Assay and Modular Microfluidic Platform for Continuous In‐Line Monitoring of Lung Metabolism During Ex Vivo Perfusion

open access: yesAdvanced Science, EarlyView.
MetaboSense is a first‐of‐its‐kind microfluidic platform enabling continuous, in‐line monitoring of glucose and lactate during ex vivo lung perfusion. Combining a quantum dot–mediated aptamer assay with mixing, depletion, and optofluidic detection modules, it achieves 60–s temporal resolution and shows strong agreement with standard blood gas analyzers,

The impact of user fees on health services utilization and infectious disease diagnoses in Neno District, Malawi: a longitudinal, quasi-experimental study

open access: yesBMC Health Services Research, 2016
Background User fees have generally fallen out of favor across Africa, and they have been associated with reductions in access to healthcare. We examined the effects of the introduction and removal of user fees on outpatient attendances and new diagnoses

Ultrafast Chemical Pre‐Sodiation of Pseudocapacitive CaV8O20 Anodes for High‐Performance Sodium‐Ion Capacitors

open access: yesAdvanced Science, EarlyView.
An ultrafast (2‐minute), gas‐free chemical pre‐sodiation strategy using Na‐benzophenone is developed to compensate for initial sodium loss in calcium vanadate (CaV8O20). Driven by the Ca2+ ‘spectator effect’, the framework enables highly reversible, quasi‐zero‐strain solid‐solution sodium storage, explicitly bypassing destructive conversion reactions ...

Association Between User Fees and Dropout from Methadone Maintenance Therapy: Results of a Cohort Study in Vietnam

open access: yesHealth Systems & Reform, 2018
—Vietnam launched methadone maintenance therapy (MMT) in 2008 with donor funding. To expand and ensure sustainability of the program, Vietnam shifted the responsibility for financing portions of MMT to provinces and, in 2015, some provinces started ...
