Abstract

We provide an overview of the experimental techniques, measurement modalities, and diverse applications of the quantum diamond microscope (QDM). The QDM employs a dense layer of fluorescent nitrogen-vacancy (NV) color centers near the surface of a transparent diamond chip on which a sample of interest is placed. NV electronic spins are coherently probed with microwaves and optically initialized and read out to provide spatially resolved maps of local magnetic fields. NV fluorescence is measured simultaneously across the diamond surface, resulting in a wide-field, two-dimensional magnetic field image with adjustable spatial pixel size set by the parameters of the imaging system. NV measurement protocols are tailored for imaging of broadband and narrowband fields, from DC to GHz frequencies. Here we summarize the physical principles common to diverse implementations of the QDM and review example applications of the technology in geoscience, biology, and materials science.

28. COVID-19 and the Gender Gap in Research Productivity: Understanding the Effect of Having Primary Responsibility for the Care of Children

Author

Peetz, David, Preston, Alison, Walsworth, Scott, and Weststar, Johanna

Abstract

In this paper we contribute to the emerging literature on the effect of the COVID-19 pandemic on the gender gap in research productivity. We extend previous studies by considering men and women academics from science and non-science disciplines through an analysis of data from academics at 14 universities across two countries (seven in Australia and seven in Canada) and focusing on the role of primary caregiving. Our empirical approach used logistic regressions and the Blinder-Oaxaca decomposition technique. The latter enabled us to ask: 'How much of the gender gap in perceived productivity during the pandemic is due to gender differences in primary care responsibilities?' Within the sample (N = 2,817) of academics, 33% of women and 25% of men reported that their perceived publication ability decreased a lot during the pandemic. This is an eight percentage-point gender gap in perceived publication ability. Statistical analysis revealed that two-fifths (40%) of this gap may be explained by gender differences in having primary responsibility for the care of children. Gender differences in other characteristics such as age, discipline, and increased teaching and administrative work were not, as a group, significant. There were also no differences between Australia and Canada. The findings are important, particularly for the pursuit of gender equality within academia. In the absence of specific mitigating interventions, research disruptions in 2020 may have long-lasting career scarring effects (e.g. hiring, promotion, tenure) and, as a result, see women further disadvantaged within the academy.

Abstract

Redd counts are commonly applied to estimate spawning population size for salmonids and allow for broad spatial and temporal coverage in monitoring efforts. However, the utility of redd counts may be compromised by observation error, particularly with respect to superimposition, where later arriving spawners construct redds overlapping existing redds. Here, we provide a mechanistic evaluation of the effects of superimposition on the error structure and biological significance of redd count data for Yellowstone cutthroat trout (Oncorhynchus clarkii bouvieri) spawning within tributaries to the Snake River, Wyoming. We used a Bayesian framework to parse observation error into distinct components and found low detection of redd clusters (i.e., areas of superimposition) was offset by overestimates of the number of redds per cluster, such that observed counts accurately reflected census redd abundance. However, a saturating relationship between redd counts and spawner abundance indicated that counts is best interpreted as effective reproductive effort rather than spawner abundance. Our results provide a mechanistic understanding of redd count data that can be used to assess their application and interpretation for monitoring. Key words: trout, superimposition, redd counts, observation error, monitoring, Bayesian model, Introduction Understanding population status and trends is critical for effectively managing and conserving species of recreational, commercial, or ecological value (e.g., Hilborn et al. 2020). Conservation targets for vulnerable and [...]

48. Benefits of stocking fewer but larger individuals with implications for native fish recovery

Subjects
Fish stocking -- Environmental aspects, Company distribution practices, Earth sciences
Abstract

Artificial propagation is commonly used to reduce extinction risk for native, imperiled fish species. Thus, identifying stocking strategies that most effectively augment adult abundance is a critical aspect of successful adaptive management. The threatened June sucker (Chasmistes liorus), endemic to Utah Lake, UT, USA, experienced major declines in abundance following extensive ecosystem degredation. Over 800 000 June sucker were stocked from hatcheries, grow-out ponds, and refuge populations from 1990-2019 across a range of sizes and seasons. Here, we evaluated post-stocking survival of June sucker using a Cormack-Jolly-Seber model with three covariates: size at stocking, origin, and season. Survival was positively correlated with size at stocking, with evidence of a possible size-selective predation threshold between 200 and 300 mm, and spring stocking appeared to produce higher survival rates than summer or fall. We also compared cost and benefit for stocking hatchery-origin June sucker at different sizes, finding that stocking fewer but larger (age-2) individuals was more cost-effective than stocking more but smaller (age-1) individuals. Our results highlight operational changes that can help maximize the efficacy of native fish hatchery programs. Key words: Cormack-Jolly-Seber model, stocking survival, imperiled fishes, cost-benefit analysis, Chasmistes liorus, Introduction Freshwater ecosystems are hotbeds of biodiversity yet are becoming increasingly imperiled due to anthropogenic disturbances, as overexploitation, pollution, flow modification, habitat degradation, and introduction of exotic species all pose [...]

50. Dressed-state control of effective dipolar interaction between strongly-coupled solid-state spins

Abstract

Abstract Strong interactions between defect spins in many-body solid-state quantum systems are a crucial resource for exploring non-classical states. However, they face the key challenge of controlling interactions between the defect spins, since they are spatially fixed inside the host lattice. In this work, we present a dressed state approach to control the effective dipolar coupling between solid-state spins and demonstrate this scheme experimentally using two strongly-coupled nitrogen vacancy (NV) centers in diamond. Through Ramsey spectroscopy on the sensor spin, we detect the change of the effective dipolar field generated by the control spin prepared in different dressed states. To observe the change of interaction dynamics, we deploy spin-lock-based polarization transfer measurements between the two NV spins in different dressed states. This scheme allows us to control the distribution of interaction strengths in strongly interacting spin systems, which can be a valuable tool for generating multi-spin correlated states for quantum-enhanced sensing.
