Machine-learned force fields have transformed the atomistic modelling of materials by enabling simulations ab initio quality on unprecedented time and length scales. However, they are currently limited by: (i) significant computational human effort that must go into development validation potentials for each particular system interest; (ii) a general lack transferability from one chemical to next. Here, using state-of-the-art MACE architecture we introduce single general-purpose ML model,...

The nature of ion–ion interactions in electrolytes confined to nanoscale pores has important implications for energy storage and separation technologies. However, the physical effects dictating structure nanoconfined remain debated. Here we employ machine-learning-based molecular dynamics simulations investigate with density functional theory level accuracy a prototypical electrolyte, aqueous NaCl within graphene slit pores. We find that free ion pairing highly deviates substantially from...

The extent of ion pairing in solution is an important phenomenon to rationalize transport and thermodynamic properties electrolytes. A fundamental measure this the potential mean force (PMF) between solvated ions. relative stabilities paired solvent shared states PMF barrier them are highly sensitive underlying energy surface. However, direct application accurate electronic structure methods challenging, since long simulations required. We develop wave function based machine learning...

Life on Earth depends upon the dissolution of ionic salts in water, particularly NaCl. However, an atomistic scale understanding process remains elusive. Simulations lend themselves conveniently to studying since they provide spatio-temporal resolution that can be difficult obtain experimentally. Nevertheless, complexity various inter- and intra-molecular interactions require careful treatment long time simulations, both which are typically hindered by computational expense. Here, we use...

e13518 Background: Anticancer drug dosing recommendations in kidney dysfunction are often empirical, based on non-standardised creatinine assays calculated via the Cockcroft-Gault equation, and lack applicability to globally accepted classifications. ADDIKD aims provide a standardised approach assessing function cancer patients, apply evidence consensus-based anticancer dysfunction. Methods: An expert international multidisciplinary working group was established develop recommendations. The...

Abstract Background Older adults and particularly older with frailty are high users of acute hospital care which results in overall higher costs reduced functional independence. Early supported discharge (ESD) was found to have a statistically significant impact reducing length stay admitted for medical reasons. This poster outlines the rehabilitation pathway developed by an ICPOP team provide early frail inpatients SMART rehab goals. Methods Suitable patients identified assessed prior from...

Abstract Background Detention orders are the inherent jurisdiction of high court. Only mechanism to support treatment in those lacking capacity and refusing care. Considered a last resort. Integrated care for older persons teams (ICPOP) often engage with complex cases who require this intervention. I aim review detention enacted on ICPOP patients within 1 year. Methods Retrospective notes all required order transfer from March 2023- 2024. Assessing patient’s primary diagnosis, expressed...
