Article Abstract
We analyze and experimentally demonstrate quantum steering using criteria based on generalized entropies and criteria with minimal assumptions based on the so-called dimension-bounded steering. Further, we investigate and compare their robustness against experimental imperfections such as misalignment in the shared measurement reference frame. While entropy based criteria are robust against imperfections in state preparation, we demonstrate an advantage in dimension-bounded steering in the presence of measurement imprecision. As steering with such minimal assumptions is easier to reach than fully nonlocal correlations, and as our setting requires very little trust in the measurement devices, the results provide a candidate for the costly Bell tests while remaining highly device independent.

Silicene is a two-dimensional silicon monolayer with a band gap caused by relatively strong spin-orbit coupling. This band gap can be steered using a vertical electric field. In turn, the change in this electric field value leads to a transition from a topological insulator to a bulk insulator regime.

Quantum randomness can be certified from probabilistic behavior demonstrating Bell nonlocality or Einstein-Podolsky-Rosen steering, leveraging outcomes from uncharacterized devices. However, in standard spot-checking protocols, such nonlocal correlations are not always sufficient for this task, necessitating the identification of required minimum quantum resources. In this Letter, we focus on the bipartite scenario and provide the necessary and sufficient condition for nonzero certified randomness under any arbitrary but fixed input, formulated in terms of measurement incompatibility.

Background: Obesity is highly prevalent among individuals with heart failure with mildly reduced ejection fraction (HFmrEF) or heart failure with preserved ejection fraction (HFpEF) and is associated with increased risk of disability and death.
Objectives: The purpose of this study is to explore the association between different adiposity-related anthropometrics and clinical outcomes in this population.
Methods: In this participant-level pooled analysis of 5 international randomized trials that enrolled adults with HFmrEF/HFpEF, the association between adiposity-related anthropometrics (body mass index [BMI], waist circumference [WC], and waist-to-height ratio [WHtR]) and heart failure (HF) and mortality outcomes was evaluated, overall and by age and sex.

Background: Mapping clinical, biomarker, and diuretic dosing trajectories before adverse clinical outcomes in patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) may inform population monitoring approaches.
Objectives: We assessed temporal patterns of 2 biomarkers (N-terminal pro-B-type natriuretic peptide [NT-proBNP] and estimated glomerular filtration rate [eGFR]), physician assigned functional status (NYHA functional class), a patient-reported outcome (Kansas City Cardiomyopathy Questionnaire Total Symptom Score [KCCQ-TSS]), and diuretic dosing leading up to a clinical event.
Methods: FINEARTS-HF was a double-blind, randomized clinical trial testing finerenone vs placebo in 6,001 patients with symptomatic HF and a left ventricular ejection fraction of ≥40%.
