Single-shot incoherent digital holography based on generalised three-step phase-shifting method with 1D phase grating
Abstract Incoherent digital holography (IDH) is a passive holographic 3D imaging technique under spatially incoherent light. Single-shot recording with high light-utilization efficiency and high spatial resolution is a challenge in IDH. Herein, we propose a single-shot three-step phase-shifting IDH system with a 1D phase grating that has a line-and-space structure. The 0th and ± 1st diffraction orders of the grating are used for simultaneously creating three self-interference holograms, which are then captured using an image sensor at a single exposure. Three-step phase shifts are introduced into the holograms using the geometric phase of circular polarizations. To compensate the intensity variations between the holograms due to grating fabrication errors, we derive and implement a generalised three-step phase-shifting algorithm. We experimentally performed the single-shot recording of reflective objects as a proof-of-principle demonstration. We further examined the theoretical noise tolerances between three- and four-step phase-shifting methods for grating-assisted space-division phase shifting. The results show that the three-step phase-shifting method is superior to the four-step method when the diffraction efficiency of the 1D phase grating is at least four-thirds higher than that of the 2D phase grating used for the four-step method.

Patient characteristics modify the association between changes in mineral metabolism parameters and mortality in a nationwide hemodialysis cohort study
Abstract In hemodialysis patients, it remains unclear whether patient characteristics influence the clinical impacts of changes in serum mineral metabolism parameters on mortality. In this 9-year cohort study, we investigated the associations between the changes in calcium/phosphate levels and all-cause mortality using a time-dependent approach after adjustment for potential confounders in groups stratified by performance status (PS), a history of atherosclerotic cardiovascular disease (ACVD), or diabetic nephropathy (DN). In patients with baseline serum calcium levels of 9.5–<10.0 mg/dL, increases in serum calcium levels were associated with higher mortality exclusively in patients with PS Grade 0. In the same baseline calcium range, a significant association was observed between reduced serum calcium levels and lower mortality only in patients with a history of ACVD or DN. Similarly, in patients with baseline serum phosphate levels of 5.0–<5.5 mg/dL, reduced serum phosphate levels were associated with lower mortality only in those with PS Grade 0, a history of ACVD or DN. These findings indicate that PS should be considered in treating mild hypercalcemia or hyperphosphatemia in hemodialysis patients. Moreover, stringent management of hypercalcemia and hyperphosphatemia in patients with a history of ACVD or DN might be associated with a better prognosis.

Study on indoor thermal environment and energy consumption of traditional dwellings of ethnic minorities in Sichuan plateau
Abstract In this paper, field tests, questionnaire surveys, and DesignBuilder were used to analyse the indoor thermal environment and energy consumption of traditional houses in a traditional ethnic minority village of Western Sichuan Plateau of China, The results showed that during the summer test period, the outdoor temperature range was 9.3–7.8 °C and the relative humidity range was 53.5–67.4%, while the indoor temperature range of the tested room was 13.3–2.3 °C, and the relative humidity range was 69.1–83.0%. The humidity is high, and the thermal environment does not meet the requirement of local standard. Therefore, corresponding energy-saving optimization measures are proposed. In the winter heating building model data, compared with the heat load before optimization, the energy saving reaches about 56.5%. In addition, the carbon emissions and economic suitability of different heating methods were evaluated. Electric heating, coal-fired heating and biomass heating have payback periods of 11 years, 24 years and 6 years respectively. With perspective focusing on the special regional and ethnic characteristics of the plateau, this research aims to promote energy conservation and sustainable development of local traditional buildings of ethnic minorities, and help improve the living environment of the Sichuan Plateau. In the future, a long-term monitoring mechanism can be established to continuously track residential buildings after the adoption of optimization measures to evaluate the actual effect of these measures.
