Hard carbon (HC) has emerged as a promising anode material for sodium-ion batteries (SIBs) owing to its superior sodium storage performance. However, the high cost of conventional HC precursors remains a critical challenge. To address this, coal─a low-cost, carbon-rich precursor─has been explored for HC synthesis.

Since the release of the Supreme Court decision in June 2022, researchers have been working to better understand the impact that the growing number of abortion restrictions are having on the provision of and access to abortion services in the United States (US). Less is known about the impact of abortion restrictions on the provision of sexual and reproductive health (SRH) services more broadly, including at clinics that do not directly offer abortion. Between November 2023 and February 2024, we conducted interviews with SRH managers, clinic managers, and other administrators at publicly funded SRH clinics around the US to generate evidence on the effects of state-level abortion restrictions on the provision of abortion and related services, such as pregnancy options counselling and abortion referrals, at facilities providing contraceptive services.

Introduction: Post-stroke spasticity can cause serious impairment, activity limitation, and participation restrictions for survivors, leading to stroke-related disability. While there are hundreds of qualitative studies regarding stroke survivor experience, the phenomenon of what it is like to have post-stroke spasticity is not well understood.
Methods: Ten community-dwelling adults with chronic stroke and upper limb spasticity who had recently participated in an intensive upper limb rehabilitation programme were interviewed.

Sensorineural hearing loss is the most common form of deafness, typically resulting from the loss of sensory cells on the basilar membrane, which cannot regenerate and thus lose sensitivity to sound vibrations. Here, we report a reconfigurable piezo-ionotropic polymer membrane engineered for biomimetic sustainable multi-resonance acoustic sensing, offering exceptional sensitivity (530 kPa) and broadband frequency discrimination (20 Hz to 3300 Hz) while remaining resistant to "dying". The acoustic sensing capability is driven by an ion hitching-in cage effect intrinsic to the ion gel combined with fluorinated polyurethane.

Purpose: Federated Learning helps training deep learning networks with diverse data from different locations, particularly in restricted clinical settings. However, label distributions overlapping only partially across clients, due to different demographics, may significantly harm the global training, and thus local model performance. Investigating such effects before rolling out large-scale Federated Learning setups requires proper sampling of the expected label distributions.
