Summary: This article presents a practical solution to the problem of detecting spectral peaks in nonuniform spectra. A robust probabilistic approach is applied, where the histogram of trimmed spectral data is fitted with a truncated Gamma distribution. The estimated distribution parameters are used to derive a threshold through a hypothesis test. The proposed approach is robust as it formulates the distribution without peaks, regardless of the number of peaks in the spectral data. The authors also suggest a preprocessing step to handle nonuniform spectra, and the methodology is validated using simulated and experimental signals.

Summary: This paper presents a Denoising Dynamic Statistical Threshold (DDST) detection algorithm for detecting Fiber Bragg Grating (FBG) spectral peaks in noisy conditions with changing Signal-to-Noise Ratio (SNR). The algorithm incorporates background noise fluctuations, nonlinear signal attenuation of a Single-Mode Fiber, and short-term interference. It uses a sliding wavelength window technique and power scaling to adjust the detection threshold and probability of false alarms (p(FA)). The algorithm improves detection robustness and resolution for overlapping FBG spectral peaks and is simple to implement.

Summary: This study utilized Raman spectroscopy to investigate the diagnostic capacity of identifying colored chromophores of fungi on paper, exploring the characteristics of chromophores and biochemistry of fungi in different regions. By conducting quantum chemistry calculations and comparing theory with experiment, specific chromophores such as fonsecin, erythroglaucin, and carotenes were identified in fungal filaments. The diverse Raman resonances observed in different spatial regions provide insights into the rich biochemistry of developing fungal structures, essential for understanding the impact of fungi on paper objects and designing new materials based on fungal hyphal mats.

Summary: The biodegradation ability of various fungi, including Diaporthe italiana, Thyrostroma jaczewskii, Collectotrichum fructicola, and Stagonosporopsis citrulli, in culturing with LDPE film as the sole carbon source has been studied. These fungi showed significant growth and degradation of the LDPE film, indicating their potential use in plastic degradation systems.

Summary: This study explored the diversity of antagonistic fungi associated with Potato Cyst Nematodes (PCN) obtained from soil samples in Kenya and evaluated their effect on PCN egg viability and hatching. Trichoderma spp. was the most abundant isolate, showing a significant reduction in PCN egg viability and hatching. These fungal isolates could be potential tools for PCN management in potato production systems, but further studies are needed to validate these findings under greenhouse and field conditions.

Summary: Endophytic fungi residing in medicinal plants have the potential to produce various bioactive compounds. In this study, three endophytic fungi were isolated from different medicinal plants and their intra- and extracellular products were analyzed. The analysis revealed the presence of bioactive metabolites and phytochemicals, and the extracts exhibited strong antibacterial and antioxidant activity. Molecular docking analysis also suggested the potential anticancer activity of certain compounds. These findings highlight the importance of endophytic fungi in natural drug development and reducing the environmental burden of synthetic drugs.

Summary: A novel classification framework, including spatial-spectral density peaks-based discriminant analysis (SSDP), is proposed for intelligent diagnosis of MN. SSDP constructs a set of graphs describing intrinsic structure of MHSI and obtains low-dimensional features for MN diagnosis. Experimental results show that SSDP achieves a sensitivity of 99.36%, indicating potential clinical value for automatic diagnosis of MN.

Summary: Microscopic filamentous fungi are adaptable microorganisms that can form biofilms on various surfaces. This study aimed to find a reliable method for measuring the biofilm growth of selected fungi strains. Multiple methods were tested, and crystal violet staining was found to be suitable for determining total biofilm biomass, while the MTT assay was suitable for determining its metabolic activity. Fluorescent stains successfully dyed the hyphae of microscopic fungi.

Summary: Liver and biliary diseases have a significant impact on global health, with the intestinal bacterial microbiome playing a well-established role. However, the role of the fungal microbiome, or mycobiome, has been overlooked for a long time. Recent studies have highlighted the importance of the mycobiome in hepatobiliary diseases, particularly the involvement of the Candida genus. This article compares colonization and infection, describes mycobiome findings in healthy and diseased states, and discusses the potential for modulating the gut mycobiome to improve hepatobiliary conditions.

Summary: Garlic, an important crop, is susceptible to fungal infection. In this study, an electronic nose was used as a nondestructive and fast method to detect fungal infection on garlic. The aroma profile obtained by the electronic nose can help identify infection at an early stage, contributing to food security.

Summary: Fungal diseases are a major challenge in the postharvest citrus industry. Some diseases reduce marketability, while others rapidly spread to adjacent fruits, making them unsuitable for storage or export. Early detection is crucial, and this paper investigates various optical methods, including imaging and spectroscopic, for identifying citrus fungal diseases.
