Summary: Source identification and sound field reconstruction using near-field acoustical holography (NAH) is challenging when the measurement data are sparse. Fast wideband acoustical holography (WBH) is an inverse solution method based on compressed sensing theory, but it is often unsatisfactory for low-frequency coherent sources. This study proposes a modified WBH method that combines conventional WBH and steepest descent methods to improve low-frequency and high-frequency performance.

Summary: This study observes the interstitial fluorine anion-doping in Sr3Fe2O7-delta for the first time, and demonstrates the impact of fluorine anion-doping on the local coordination environment of oxygen electrodes, as well as its effect on the activation of oxygen ions. Density functional theory calculations verify the insertion of fluorine anions into tetrahedral intervals and the alteration of ion proportion in the tetrahedra. The fluorine anion-doped oxygen electrode exhibits improved performance and higher peak power density within the temperature range.

Summary: A reconstruction algorithm based on multi-dictionary learning (MDL) is proposed to improve the reconstruction quality of acoustic tomography for complex temperature fields. The algorithm aims to address the under-determination of the inverse problem by utilizing the sparse representation of sound slowness signal. Simulation and actual temperature distribution reconstruction experiments demonstrate that the MDL algorithm outperforms other algorithms in terms of reconstruction accuracy.

Summary: The purpose of this study was to compare the rates and time to union of open tibia fractures that underwent soft-tissue coverage. The results showed that flap type significantly affected time to union, with muscle flaps having shorter time to union than fasciocutaneous flaps. Moreover, patients who underwent an initial soft-tissue reconstruction with a local muscle flap were more likely to require a second flap.

Summary: This paper presents a methodology for joint cosmological analysis using weak gravitational lensing and galaxy clustering data from multiple surveys. The analysis incorporates cross-correlations, develops a hybrid model for non-linear scales, updates calibration procedures, and assesses signal contributions from astrophysical effects. The study also validates likelihood and goodness-of-fit statistics, introduces a new prior on the structure growth parameter, and proposes an alternative estimator for S-8 weak lensing constraints. Systematic effects are shown to bias S-8 by no more than 0.1 standard deviations, with expected improvements in S-8 constraints compared to previous analyses.

Summary: This study combines weak gravitational lensing observations from KiDS-1000, redshift-space galaxy clustering observations from BOSS, and galaxy-galaxy lensing observations from overlapping surveys to constrain the structure growth parameter S-8, resulting in a discrepancy with the Planck observations by 8.3% relative to Planck. The systematic uncertainties identified through various analyses are incorporated into the cosmological analysis, revealing a tension in the matter fluctuation amplitude parameter, sigma(8).

Summary: This study presents weak lensing shear catalogues from the KiDS-1000 survey, evaluating the accuracy of the PSF model and validating the shear estimates. No significant non-lensing B-mode distortions were found in the data, with low amplitude of PSF residuals detected in the highest-redshift bins. The joint KiDS-1000 shear and photometric redshift calibration is deemed sufficiently robust for combined-probe gravitational lensing and spectroscopic clustering analyses.

Summary: This study introduces an improved framework for estimating the growth rate of large-scale structure, by utilizing measurements of galaxy-velocity cross-correlation. By considering various standard estimators and introducing a new estimator, along with analyzing covariance and minimizing chi(2), accurate estimates and errors for the growth rate can be determined. Testing the framework on mock data sets has shown a significant reduction in statistical uncertainty by combining different correlation statistics.

Summary: We evaluated the performance of the multipole expansion formalism in single-dish HI intensity mapping with consideration of instrumental and foreground removal effects. Our analysis provides Markov chain Monte Carlo forecasts for HI and cosmological parameters, and shows that foreground subtraction effects can introduce biases in parameter estimation. By constructing a two-parameter foreground modeling prescription, we achieve unbiased parameter estimation at the cost of increased uncertainties in cosmological parameters.

Summary: This study presents galaxy redshift distribution estimates for the KiDS-1000 data, crucial for weak gravitational lensing measurements. Utilizing deep spectroscopic reference catalogues and self-organising map (SOM), the redshift distributions were accurately calibrated and validated, providing alternative calibration with only slightly larger uncertainties for cosmological weak lensing analyses.

Summary: In this study, a new experimental design using clustering-based redshift inference was used to measure the evolving galaxy luminosity function (GLF). The results showed a relatively constant power-law slope for a certain range of magnitudes and a sharp increase thereafter, which may be attributed to the dominance of globular clusters.

Summary: Lensing without borders is a cross-survey collaboration aimed at assessing the consistency of galaxy-galaxy lensing signals across different data sets and testing systematic errors. The study compares the amplitude of Delta sigma using lens samples from different surveys and finds good agreement between empirically estimated and reported systematic errors. A correlation between lensing amplitude and survey depth is detected in some lenses, possibly due to unrecognized galaxy blends and imperfections in photometric redshift calibration. The analysis suggests that lensing systematics alone are unlikely to fully explain the 'lensing is low' effect.
