Summary: This study characterizes the morphology of intermediate to silicic lava flows and investigates their relationship with thickness distribution, pre-surface slope, composition, and rheology. It is found that the pre-eruptive slope, effusion rate, and viscosity of the lava play important roles in determining the lava flow morphology. Four main types of lava flows are identified based on the analysis of 49 intermediate to silicic lava flows.

Summary: In this study, the value of polarimetric information in observing lava flow is discussed. Dualpolarimetric Synthetic Aperture Radar (SAR) measurements are processed using a polarimetric change detector that detects changes in the polarimetric scattering behavior instead of the backscatter intensity variation. The results show that the proposed polarimetric approach correlates well with the footprint of the lava flow and outperforms conventional single-polarization measurements.

Summary: Firearm related evidence plays a significant role in forensic science. Researchers have been exploring the value of organic gunshot residue (OGSR) evidence, including factors like recoverability. Raman spectroscopy and LIBS are two nondestructive and rapid techniques used in this study to identify and characterize OGSR particles from closely related ammunition types. The goal is to differentiate between ammunition types of the same caliber and manufacturer, generated under identical firing conditions.

Summary: We investigated the mineralogy, petrography, and structural characteristics of organic matter (Corg) in three different types of DST nodules. The Raman spectra analysis showed that the Corg underwent low-grade metamorphism and exhibited structural heterogeneities in the center, rim, and host rock. The structural characteristics of Corg also showed distinct preferences for different mineral matrices, indicating different mineral-organic interactions during the formation of nodules.

Summary: Rapid identification of newly emerging or circulating viruses is crucial for managing public health responses. A portable virus capture device paired with label-free Raman spectroscopy enables fast detection and recognition of viruses using a machine learning approach. A convolutional neural network classifier achieves high accuracy in analyzing Raman spectra of human and avian viruses.

Summary: Rapid identification of newly emerging or circulating viruses is crucial for public health response. A study presents a machine learning approach coupled with label-free Raman spectroscopy for fast virus detection and identification. The method achieves high accuracy for various virus type or subtype identification tasks and highlights important Raman spectral ranges for virus identification. The study verifies that the machine learning model effectively recognizes the Raman signatures of proteins, lipids, and other functional groups in different viruses.

Summary: This study presents the design, additive manufacturing, and testing of a small-scale cavity flameholder for high-speed premixed ethylene combustion. The effects of flow compressibility and heat release on turbulent flame structures and stabilization mechanisms are comprehensively studied. The final design allows for sustained ethylene flame for over an hour of repeated cycles.

Summary: Non-invasive, rapid, on-site detection and identification of body fluids is important in forensic investigations. This study investigated the fluorescent properties of different body fluids and found specific fluorescent signatures for their identification. The results showed that fluorescent behavior can be used as a non-invasive tool for body fluid identification, improving the current guidelines and providing robustness to fluorescence-based methods.

Summary: The study investigates the effectiveness of the Q-LavHA algorithm in simulating lava flows in Gran Canaria and finds that the probabilistic Maximum Length constraint provides the best simulations. Most simulations almost entirely overlap with the actual lava flow, with some cases of relatively high overestimated areas and generally low underestimated areas.

Summary: Nevados de Chillan volcanic complex (NChVC) in Chile is one of the most active volcanoes, with the last eruption in 2008 and reactivation starting in 2016. Seismic activity includes a variety of waveforms, and the eruption phases are divided into five stages, involving lava flows, lava dome extrusion, and constant vulcanian type eruptions.

Summary: Kallistos Vallis is a channel system on Venus that extends over 1200 km from a source region marked by a graben-like feature and chaotic terrain, terminating at plains covered in volcanic flows. The channels are wide, reaching tens of kilometers, with prominent streamlined erosional residuals. The topographic disturbances at the head of Kallistos Vallis are likely caused by a deep-rooted igneous plumbing system, which transported large volumes of mafic or ultramafic magma to the surface. The development of the system could have occurred in tens of days, but multiple eruptive episodes separated by longer periods of inactivity are also possible. The minimum total volume of lava required for the development of Kallistos Vallis is estimated to be around 7000 km(3), suggesting significant differences between the volcanism on Venus and modern Earth.

Summary: This study analyzed 27 radar observations from the Mars Reconnaissance Orbiter to identify subsurface structures in the Echus-Kasei region on Mars. These structures were found beneath recent lava flows and are of interest for understanding the late Amazonian volcanic, fluvial, and glacial activities on Mars.

Summary: The volcanic (lava tube) caves at Lava Beds National Monument in Northern California, USA, serve as a valuable terrestrial analog for studying volcanic caves on Mars and the Moon. By analyzing the chemical composition of speleothems and cave waters in terrestrial volcanic caves, insights into the formation of speleothems and records of paleoenvironmental changes can be revealed.

Summary: In Roman wall paintings, blue and green pigments were less commonly used compared to red and yellow due to their higher cost. The nomenclature and composition of these pigments, such as Egyptian blue for blue and celadonite, glauconite for green, sometimes lead to confusion. This study evaluates the Raman spectroscopic identification of Roman blue and green pigments used in wall paintings, aiming to clarify their nomenclature.

Summary: The parameters involved in variscite colors were determined through a 3D study of the distribution of mineral phases. The study found that depth is not directly related to color. The content of Cr3+ in variscite affects its color, and when mixed with white minerals such as quartz or kandite, the colors of variscite and turquoise become paler.
