Summary: Further developments in luminescence dating, dosimetry and temperature-sensing require a deep understanding of luminescence processes and their driving parameters. The lack of suitable natural reference samples is identified as a pivotal problem impeding significant progression. This study presents a multi-technique luminescence comparison of two natural quartz samples, demonstrating fundamental differences in signal composition and sensitivity.

Summary: Loess deposits in southeastern China are important for paleoclimate reconstruction. Luminescence dating of a loess-paleosol sequence in northern Jiangsu Province using SAR-OSL and pIRIR protocols revealed accurate ages up to -70 ka, confirming Last Glaciation deposition. However, beyond 70 ka, quartz ages are underestimated while pIRIR ages are likely overestimated, highlighting the challenges of dating methods for older samples.

Summary: This study used different methods to date quartz samples from the Lingjiatan archaeological site in China. The results showed two types of OSL characteristics in the samples, corresponding to different heating temperatures. By modifying the OSL-SAR measurement conditions, the ages of most samples were successfully determined.

Summary: The parameters of traps in quartz play a crucial role in determining the thermal stability and dating range of OSL components. Recent research has found an effective method for separating the fast OSL component in quartz using the thermally modulated OSL (TM-OSL) method. By comparing the trap parameters obtained through different methods, it was found that the values stay consistent for quartz samples from different origins. The new approach of measuring OTDCs with the TM-OSL method enables the best precision and the obtained trap parameters are consistent with literature data.

Summary: The fluvial terraces along the Minjiang River in China's Songpan area were investigated and dated using optically stimulated luminescence (OSL) techniques. The reliability of previously reported terrace ages was evaluated, and relatively reliable ages were determined based on stratigraphic and geomorphological consistency. The study provides important information on terrace formation ages and river incision rates.

Summary: This study aimed to investigate the genesis and evolution of remnant wet soils under buriti palms/palm swamps in the Brazilian semiarid. Our results show that remnant wetlands are associated with dynamics of the hydrogeological conditions and the regional relief, strongly influenced by the morphostructure and the current morphogenesis of the Araripe Plateau.

Summary: The Achajur loess-palaeosol section in northeastern Armenia consists of three prominent pedocomplexes with intercalated loess units, spanning at least three glacial-interglacial cycles. The Sevkar loess area, serving as a bridge between loess sections in southeastern Europe and Central Asia, plays a crucial role in establishing a numerical chronology and reconstructing the paleoenvironment of the region. Luminescence dating on fine grain material was used to study the last glacial-interglacial cycle, showing deposition during dry phases in MIS3 and 4, and formation of pedocomplexes during wetter phases in MIS5 and MIS6.

Summary: Through extensive field investigation in the Zoige Basin of the eastern Tibetan Plateau, a typical sedimentary profile was found, which provides powerful evidence for the transformation of the Zoige paleolake environment into the Yellow River paleo-river environment. The study also has important scientific significance for understanding the evolution of river-lake water systems and the formation of the Yellow River source water system in the eastern Tibetan Plateau.

Summary: This study used the optically stimulated luminescence (OSL) dating method to determine the formation time of Kobresia mattic epipedon (ME) on the northeastern Qinghai-Tibetan Plateau (NE-QTP). The results showed that aeolian dust deposition was an important source of ME parent materials, and modern ME formation mainly occurred in the Late Holocene, taking an average of 0.9 ka to form a majority thickness of about 20 cm ME. The average deposition rate (DR) of MEs was 0.3 +/- 0.04 mm·a-1, and the mass deposition rate (MDR) was 346.3 +/- 45.9 g·m-2·a-1, which was similar to the flux of modern atmospheric fallen dust. Most MEs were formed by aeolian dust aggradation.

Summary: Using luminescence to date rock surfaces has revolutionized geochronology. The opacity of the rock, total insolation, and incidence angle of sunlight significantly affect the bleaching depth, which follows seasonal cycles. Calibration samples should have the same lithology, location, and orientation.

Summary: This study investigates the history of climate variability during the last glaciation in the Tibetan Plateau (TP) using loess deposits in the eastern TP as an archive. Through dating techniques and environmental proxy analysis, the researchers establish a reliable chronology and reconstruct the dust activities and environmental variation. The results show that wind-blown loess in this region started accumulating at least 60 thousand years ago and experienced high variability during the last glacial period.

Summary: This study demonstrates the potential of using OSL laser scanning to improve the resolution and parameter extrapolative precision of depth profiles in rock samples. By filtering out non-quartz OSL anomalies, the resolution and parameterization of the depth profile datasets can be further improved. However, scatter in the scanning datasets affects the absolute uncertainty of parameterization, which can be mitigated with optimized instrumentation and scanning protocols.

Summary: In this study, Fricke gel dosimeters were prepared and irradiated to investigate color changes and oxidation processes. The results showed no significant differences in the oxidation effect on the dosimeters within the investigated dose range. This study suggested that colorimetric analysis, combined with the spectrophotometric one, can be a useful tool for characterizing the samples.

Summary: This study investigated the footwall of the Paganica normal fault, the source of the 2009 L'Aquila earthquake in Italy, using integrated geological and geomorphological approaches. The results showed that the fault activity led to long-term fluvial incision and footwall uplift. The research also found an increasing relief growth and suggested that the fault's ongoing activity might trigger larger seismic events.

Summary: This study compares two methods for organ dose evaluation in CT: an experimental method using radiochromic films and a computational method using commercial software. The results show the potential of EBT-3 in CT patient dosimetry, as its lower angular dependence compensates for low sensitivity in the diagnostic dose range compared to XR-QA2.

Summary: This research focuses on developing a sensor using Sansevieria plants to measure UV-A radiation. The sensor utilizes soils, plants, metabolic processes, and bacterial activities to overcome environmental pollution caused by silicon-based solutions. The sensor does not emit CO2 during production and can reduce existing CO2 in the environment through natural photosynthesis. The study introduces the concept of a living sensor based on Sansevieria and analyzes its performance in measuring radiation.
