Material Selection through Accelerated Aging Enables >95% Performance Retention of a Perovskite–Silicon Tandem Solar Cell after 1 Year of Outdoor Monitoring

Abstract In order to ensure that the degradation modes of perovskite–silicon tandem solar cells exacerbated by accelerated aging tests are relevant to those observed under real-world operating conditions, accelerated testing should be developed in line with outdoor monitoring. He...

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Doping is a cornerstone strategy for enhancing charge transport in semiconducting polymers, important for their application in, for example, semi-transparent electrode materials, thermoelectric devices, and antistatic coatings. Both chemical and electrochemical doping have, for t...

The postsynaptic scaffolding protein SAPAP3 shapes mitochondrial activity: the case of Huntington’s disease

Abstract Postsynaptic scaffolding protein SAP90/PSD95-associated protein 3 (SAPAP3) modulates cortico-striatal signalling and regulates the maintenance of synaptic structure. Notably, SAPAP3 defects have been reported in several human psychiatric disorders that share pathophysiol...

Drainage divide dynamics modulated by erosion-driven landscape adjustment in a low-deformation setting

The Vosges Mountains (northeast France) are a mid-altitude mountain range with peaks reaching ∼1500 m a.s.l., in a low-deformation setting. Despite this, they maintain significant topographic relief (up to ∼1000 m), characterized by deeply incised valleys and broad, rounded uplan...

Soft Foam Polyurethane Recycling and Foaming in Reactive Extrusion Using Partial Aminolysis and a Latent Cross-Linking Chemistry

Abstract Polyurethane (PU) foams are widely used as thermosets and yet poorly recycled due to their generally cross-linked nature and the difficulty in recovering their isolated monomers from chemical recycling processes. A mechanochemical recycling process was demonstrated in th...

STABILOOP, a cohort trial to assess automated insulin delivery in the management of patients living with type 1 diabetes who are eligible for islet transplantation

A limited subset of people living with type 1 diabetes (T1D) is affected by extreme glycemic lability and frequent unpredictable severe hypoglycemia, significantly impairing quality of life and associated with higher morbidity, mortality, and healthcare costs. Islet transplantati...

Improving ADRC Strategy for DC-Link Voltage Regulation in PV Grid-Tied Four-Leg Inverters Using an Adaptive Nonlinear High-Gain Observer

In practical photovoltaic grid-tied four-leg inverter systems (PV-GTFLIs), changes in radiation, temperature, and grid voltage magnitude cause significant disturbances, including DC-link voltage disturbance and power unbalance, which can impact the system’s dynamic responses, con...

Nested contextual change and the temporal compression of episodic memory

Abstract How does the structure of events influence the when and the where of life experiences in comparison to the what? We developed a novel virtual reality (VR) environment to understand how the quantity of information within nested structures influence participants’ memory fo...

Behavioral changes preceded by subthalamic nucleus activity alterations in a progressive macaque model of Parkinson’s disease

Abstract Parkinson’s disease (PD) is diagnosed after motor symptoms appear, although non-motor symptoms emerge years earlier. Following years of pharmacological treatment, high-frequency stimulation (HFS) of the subthalamic nucleus (STN), a key hub in goal-directed behaviors, can...

Alcohol and tobacco in cancer: A unified framework of interaction across carcinogenic pathways and cancer types

Background Alcohol and tobacco are among the leading preventable causes of cancer worldwide and frequently co-occur. While both are well-established independent carcinogens, their combined effects remain insufficiently characterized and inconsistently interpreted across cancer ty...
