Humans handle uncertainty poorly. Prospect theory accounts for this with a value function in which possible losses are overweighted compared to possible gains, and the marginal utility of rewards decreases with size. fMRI studies have explored the neural basis of this value function. A separate body of research claims that prediction errors are calculated by midbrain dopamine neurons. We investigated whether the prospect theoretic effects shown in behavioral and fMRI studies were present in midbrain prediction error coding by using the feedback-related negativity, an ERP component believed to reflect midbrain prediction errors. Participants' stated satisfaction with outcomes followed prospect theory but their feedback-related negativity did not, instead showing no effect of marginal utility and greater sensitivity to potential gains than losses.

Background: Pulmonary rehabilitation (PR) is increasingly offered to patients who have undergone lung resection for non-small-cell lung carcinoma (NSCLC) as it can improve exercise tolerance and quality of life. However, designing and implementing such a complex multidisciplinary programme has its challenges.
Objective: This study aims to explore perspectives of patients offered PR services post-lung resection for NSCLC to gain an understanding of the potential barriers and facilitators behind implementing and designing PR programmes.

Liquid crystals (LC) are widely used in various optical devices due to their birefringence, dielectric anisotropy, and responsive behavior to external fields. Enhancing the properties of existing LCs through doping with nanoparticles, including semiconductor quantum dots, offers a promising route for improving their performance. Among various nanoparticles, QDs stand out for their high charge mobility, sensitivity in the near-infrared spectral region, and cost-effectiveness.

Low-cost and effective electrocatalysts are critical for energy storage and conversion. Herein, iron(III) and vanadium(III) acetylacetonates were first adsorbed and confined in porous zeolitic imidazolate framework-8 (ZIF-8), which further cross-linked together by the methanol-induced-assembly. Following the pyrolysis, the FeVO nanoparticles were efficiently encapsulated within three-dimensional (3D) N-doped interconnected porous carbon, termed FeVO/NIPC.

Background: Empirical reviews suggested that cryptoglandular anal fistulas require surgical resolution. However, some reports have indicated the possibility of nonsurgical and conservative treatment, which is discussed in this review.
Methods: This review explores the potential of nonsurgical approaches for curing anal fistulas through bacterial inhibition and immunomodulation.
