Summary: The proposed method utilizes Spatially Offset Raman Spectroscopy (SORS) to estimate the reduced scattering coefficient (mu(s)') of turbid samples, with high accuracy achieved through calibration on a PTFE model sample. Knowledge of mu(s)' in the NIR range is valuable for optimizing SORS illumination and geometric configurations, providing in-depth information about SORS measurements, and benefiting various photon applications in fields such as biomedical, pharmaceutical, security, forensic, and cultural sciences.

Summary: This study investigated the effects of adding different proportions of oat beta-glucan on the texture and sensory attributes of goat milk yogurt. Microfluidization was found to improve the texture instability, while oat beta-glucan suppressed the goaty and salty taste. However, a higher proportion of oat beta-glucan resulted in a stronger cereal taste and lower acceptability of the product.

Summary: This study aims to assess the material anisotropy noninvasively with as few measurements as possible. We evaluate different methods for detecting anisotropy using sample rotations, perpendicular planes of incidence, and single observation. Anisotropy is estimated by fitting ellipses to diffuse reflectance isocontours, and the robustness of this method is assessed as the number of observations is reduced. Additionally, a machine learning model is proposed to support the validity of the ellipse fitting method for estimating material anisotropy.

Summary: This article introduces a simple multiwavelength, multireflectance spectroscopic technique called MRS-Technology, which is suitable for monitoring constituents in suspensions and emulsions. By measuring the reflectance from small and large measuring volumes, the reduced scattering coefficient and the sum of the reduced scattering coefficient and absorption coefficient can be determined. Analytical and numerical results show the potential of MRS-Technology for analyzing milk samples.

Summary: Various diseases are linked to microvascular dysfunctions, and the SP-DRI technique is a non-invasive way to diagnose microcirculation conditions. The modulation parameter K is closely associated with capillary diameter and serves as a reliable indicator for evaluating microcirculation. SP-DRI is emerging as a crucial tool for early and convenient diagnosis of microcirculation-related diseases.

Summary: A coarse oil-in-water emulsion was prepared using whey protein hydrolysate-citric pectin complex. The emulsion was further homogenized to obtain different droplet sizes. Reduced-fat yogurt variations were prepared using the emulsion, with smaller droplet sizes showing higher overall acceptability. The viscosity and viscoelastic moduli were lower for the reduced-fat yogurt compared to full-fat yogurt.

Summary: This study found that increasing the number of alfalfa rows and maize density can improve the land equivalent ratio of narrow-strip intercropping, with the 1M3A arrangement under high maize density showing synergistic production of maize and alfalfa. Intercropping significantly reduced the incidence of the invasive fall armyworm, highlighting the potential for ecological pest control and sustainable maize production through intercropping.

Summary: As the complexity of aligning a feed antenna to a steerable reflectarray increases at higher mm-wave frequencies, illuminating the structure from the far field becomes desirable. However, the cost and size limitations of large arrays lead to spill-over feed radiation and specular reflections that degrade the far-field pattern of the array. To address this issue, this paper proposes three designs that reduce specular reflections of a planar surface caused by obliquely-incident waves at 240 GHz. The designs are evaluated by measuring the frequency dependency of specular reflection and far-field pattern of a small array, and the results show significant attenuation.

Summary: Diabetic foot ulcers are a common cause of lower-extremity amputation in diabetic patients globally. Researchers have identified optical diagnostic techniques for monitoring blood oxygenation in foot tissue, but DRS may offer a feasible solution for localized blood volume extraction. Preliminary results suggest that DRS could provide real-time, noninvasive monitoring of blood oxygenation in diabetic foot ulcers.

Summary: High-contrast gratings (HCG), specifically pedestal HCG (PHCG), show enhanced performance compared to conventional HCG for label-free detection of biomarkers. PHCG demonstrated an improvement of 11.2% in bulk refractive index sensitivity and 10.5% in surface sensitivity. For the detection of avidin as a model analyte, PHCG achieved a lower limit of detection (LoD) of 2.1 ng/mL and a lower limit of quantification (LoQ) of 85 ng/mL, significantly better than the values obtained with conventional HCG.

Summary: Crystallisation fouling is a challenge in various applications and understanding the basic mechanisms is crucial in mitigating fouling. In this study, we conducted in situ investigation of dynamic effects using X-ray micro-computed tomography (mu CT) to analyze the fouling process in a steel pipe. Advanced segmentation techniques were employed to quantify the evolving fouling based on 4D images. Computational fluid dynamic simulations were performed using experimental geometries to understand the impact of pipe interface structure on reactive transport. The study identified three growth phases: initiation, expansion, and densification.

Summary: This review article summarizes recent advances in the role of processing on the surface roughness of AM-printed polymers and provides a benchmark for surface quality improvement in AM processes. The impact of four AM techniques (FFF, SLS, VPP, MJT) on the surface roughness of polymeric parts is discussed by analyzing key processes and printing parameters. Comparable research summaries are provided to assist in selecting the most appropriate method of 3D printing, and a detailed survey of current techniques, process parameters, roughness ranges, and their applicability in achieving surface quality improvement in as-printed polymers is presented.

Summary: The clinical significance of tumor-immune interaction in breast cancer has been established. Tumor-infiltrating lymphocytes (TILs) have emerged as predictive and prognostic biomarkers for patients with triple-negative and HER2-positive breast cancer. The use of machine learning (ML) to automatically evaluate TILs has shown promising results. However, there are challenges in implementing this in trial and routine clinical management, including technical slide issues, ML and image analysis aspects, data challenges, and validation issues.

Summary: Selective laser sintering (SLS) is a well-established additive manufacturing technology. Efforts have been made to improve SLS by optimizing powder deposition, laser parameters, and temperature settings. This study evaluated the surface roughness and grain size differences of curved objects manufactured using a new SLS technology featuring two CO laser sources. Significant differences were found in some surface roughness and grain size measurements when varying build setup, presence of thin walls, and sample position on the powder bed.

Summary: The penetration depth of optical coherence tomography (OCT) is greater than conventional microscopy, but signal reduction with depth is a challenge. This study explores the role of multiple scattering in OCT image contrast and introduces a geometry that separates the incident and collection fields, enhancing contrast at depth. Theoretical and experimental results demonstrate a significant improvement in contrast, with a ninefold enhancement observed in biological samples.

Summary: Spectral X-ray computed tomography (SCT) is a promising technique for non-destructive imaging. The proposed correction method, based on spectral deep learning, efficiently reduces streaking artifacts in all energy channels. Additional information in the energy domain is crucial for restoring the quality of low-energy reconstruction affected by metal artifacts.
