Abstract We reduced image noise in broadband full‐color holographic capture a compact self‐interference incoherent digital holography (SIDH) system by combining cholesteric liquid crystal (CLC) circular polarizer with quarter‐waveplate‐based geometric phase lens (QW‐GPL). To address chromatic wavefront issues commonly found conventional half‐waveplate‐based SIDH systems, we explore incorporating GPL In particular, resolve angular polarization‐dependent QW‐GPL modulation utilizing circularly polarized Bragg reflection of CLC as polarization filter. This approach ensures an ideal beam state across wide range incident angles and wavelengths. By effectively mitigating distortion QW‐GPL, our method significantly improves the quality reconstructed images form factor, demonstrated entropy values.

Biological tissue consists of various molecules. Instead focusing on a particular molecule, we consider the Shannon entropy which is calculated from abundance different molecules at each spot in tissue. The spatial distribution interest. In this paper, first obtain heat map perplexity, whose logarithm entropy. To characterize variety molecules, propose scalar k that concerned with coarse-graining perplexity map. verify usefulness number, experiments mass spectrometry imaging were performed for mouse kidneys. We found k has large values renal pelvis area, cortex veins, and arteries kidney, whereas fractal dimensions fail to distinguish those regions. Published by American Physical Society 2024

A single breast cancer is a prevalent form of cancer, affecting over 2.3 million women worldwide, as reported by the World Health Organization. Recently, researchers have extensively explored utilization biomaterials in theranostics. One notable biomaterial being investigated various structures copper sulfide (CuS). In this work, microsphere (MS) structure composed CuS was employed for label-free imaging MCF-7 cells and normal Vero cells, respectively. Various techniques, such bright field, dark phase contrast (PC), differential interference (DIC), were to capture images MSs, cell, intact MSs within cell. The study compared outcomes each technique determined that DIC provided highest resolution incubated with MSs. Furthermore, combination PC techniques proved be effective conjunction This research underscores potential cell detection emphasizes significance selecting appropriate attain high-quality field observation.

ABSTRACT Accurate grading of gliomas is critical to guide therapy and predict prognosis. The presence microvascular proliferation a hallmark feature high grade which traditionally requires targeted surgical biopsy representative tissue. Superb imaging (SMI) novel resolution Doppler ultrasound technique can uniquely define the architecture whole tumours. We examined both qualitative quantitative vascular features captured with SMI, analysing flow signal density, vessel number, branching points, curvature, angle deviation, fractal dimension, entropy. Results indicate that high-grade exhibit significantly greater complexity disorganisation, increased dimension entropy, correlating known histopathological markers aggressive angiogenesis. integrated ROC model achieved accuracy (AUC = 0.95), highlighting SMI’s potential as non-invasive diagnostic prognostic tool. While further validation larger datasets required, this study opens avenues for SMI in glioma management, supporting intraoperative decision-making informing future
