Results of theoretical and experimental studies of the method of the near-field microwave tomography of the thorax are presented. Integral equations of inverse tomography problem of 3D blood- and air content inhomogeneities by data of multisensory measurements are obtained. Methods of air and blood content profiling in processes of breathing and heart activity by data of bistatic measurements of the scattered signal are proposed and solving algorithms of inverse problems are studied in the numerical simulation. Multifrequency and pulse measurements of scattered signals are carried out in processes of cardiorespiratory activity. By data of bistatic measurements of scattered signals parameters from the thorax, profiling relative air- and blood content profiles has been realized. Application possibilities of the method in the biomedical diagnostics are considered.

Knowledge claims may play an essential role in reproductive decision-making, as individuals seek out, assess, reject, and use information about health and fertility gathered from numerous sources. This paper focuses specifically on childless women’s self-perceptions of knowledge about infertility and age-related fertility decline. How knowledgeable do childless women perceive themselves to be about fertility and infertility in general, and from where they do they obtain this knowledge? Furthermore, how knowledgeable do childless women perceive themselves to be about their own fertility and ability to conceive, and to what do they attribute this knowledge? Data for this project was gathered through semi-structured interviews with 72 childless American women; the interviews were inductively and thematically coded using qualitative-analysis software. Childless women assessed their general knowledge of fertility as confident, self-doubting, or novices, and they claimed multiple sources as the basis of this knowledge, including formal education and training, media and popular culture, and family members and peers. When assessing knowledge about their own fecundity, the women tended to rely on two additional sources: biomedical diagnostics and embodied knowledge. Childless women’s awareness of average statistics of age-related fertility decline did not necessarily translate to individual self-knowledge about their own bodies and fecundity. Because knowledge claims were based on multiple information sources given unequal weight, this raises questions about authoritative knowledge—that is, the knowledge that “counts” for women as they make decisions regarding their future childbearing.

AbstractSpectroscopy is a well-established nonintrusive tool that has played an important role in identifying and quantifying substances, from quantum descriptions to chemical and biomedical diagnostics. Challenges exist in accurate spectrum analysis in free space, which hinders us from understanding the composition of multiple gases and the chemical processes in the atmosphere. A photon-counting distributed free-space spectroscopy is proposed and demonstrated using lidar technique, incorporating a comb-referenced frequency-scanning laser and a superconducting nanowire single-photon detector. It is suitable for remote spectrum analysis with a range resolution over a wide band. As an example, a continuous field experiment is carried out over 72 h to obtain the spectra of carbon dioxide (CO2) and semi-heavy water (HDO, isotopic water vapor) in 6 km, with a range resolution of 60 m and a time resolution of 10 min. Compared to the methods that obtain only column-integrated spectra over kilometer-scale, the range resolution is improved by 2–3 orders of magnitude in this work. The CO2 and HDO concentrations are retrieved from the spectra acquired with uncertainties as low as ±1.2% and ±14.3%, respectively. This method holds much promise for increasing knowledge of atmospheric environment and chemistry researches, especially in terms of the evolution of complex molecular spectra in open areas.
