An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented

Confined Hot Carrier Cooling Via Excited‐State Energy Gap Engineering in Graphyne Carbon Allotropes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The excited‐state energy gap (EEG), regulated by the concentration of sp‐hybridized carbon, provides an effective handle for tuning electron–phonon coupling behavior. This design enables long‐lived confinement of hot carriers near the top of the EEG with controllable energy levels.

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.

Honesty in Difficult Conversations: Insights From Healthcare Professionals

open access: yesEuropean Journal of Social Psychology, EarlyView.
ABSTRACT When being honest is expected to cause emotional distress to those it concerns, it can be difficult to practice. This study examines how honesty is understood and accounted for in situations of emotional, moral and relational complexity. Drawing on semi‐structured interviews with 16 Danish healthcare professionals (8 doctors and 8 nurses), we ...
