The issue of new nuclear power is once again high up on the public policy agenda in many countries, and candidate sites for new civilian stations are likely to include those that have existing nuclear facilities. A common assumption is that existing nuclear communities will be more accepting of new build because of the direct economic and other benefits nuclear power already makes to a local area. Surprisingly, there is a dearth of contemporary data on perceptions of the risks, benefits, and values associated with nuclear power within such communities. This study uses Q-methodology to investigate the perspectives on living with nuclear risk among people (n = 84) drawn from communities near to two nuclear power stations in the United Kingdom. Both stations, at Bradwell-on-Sea and Oldbury-on-Severn, had been in operation for over 40 years. The Q-analysis identified four main perspectives, or points of view, accounting for 53% of total variance. These were interpreted as: Beneficial and Safe; Threat and Distrust; Reluctant Acceptance; and There's No Point Worrying. We conclude that the "landscape of beliefs" about nuclear power in such communities is both subtle and complex, avoiding simplistic bipolar dichotomies such as "for" or "against," and that there is a need for extensive and meaningful dialogue with such communities over any new build plans. The usefulness of Q-methodology for investigating the ways in which people live with risk is highlighted, as are the implications of the results for theories of risk and trust.

Plutonium-238 (Pu) is a scarce heat-source radioisotope used in nuclear batteries, which is produced by in-reactor irradiation of Americium-241 (Am) or Neptunium-237 (Np). Optimizing the neutron spectrum can improve the production efficiency of Pu, but currently, it is still a lack of knowledge about the optimal neutron spectrum for Pu production. Genetic algorithms and burnup algorithms are combined to identify optimal neutron spectra for Pu production under various irradiation times and flux levels, and build an optimal neutron spectrum database, which answers the questions "What is the optimal neutron spectrum for Pu production?" and "What is the maximum efficiency for Pu production" once and for all.

Bacterial biofilms, complex microbial communities encased in a protective extracellular matrix, pose a significant threat to public health due to their inherent antibiotic resistance. This review explores the potential of peptides, particularly antimicrobial peptides (AMPs), as innovative tools to combat biofilm-related infections. AMPs, characterized by their potent antimicrobial activity and tissue permeability, offer a promising approach to overcome the challenges posed by biofilms.

The testing and modeling of semiconductor devices are the foundation of circuit design. The issue of high-power device testing urgently needs to be solved as the power level of the devices under test (DUTs) increases. This work proposes advanced measurement methods based on three aspects of "measuring capability, security, and stability" with a focus on the features of high output power, easy self-oscillation in mismatch tests, and safety risk in the measurement system of high-power transistors.

Near-surface wind speed (NSWS), a determinant of wind energy, is influenced by both natural and anthropogenic factors. However, the specific impacts of volcanic eruptions on NSWS, remain unexplored. Our simulations spanning the last millennium reveal a consistent 2-year global NSWS reduction following 10 major historical eruptions.
