Summary: This paper discusses the theory and application of calibration curve experiments in a zinc bioavailability study with broiler chickens. Four commonly used methods of calculating bioavailability are compared, and the Abductive Method is found to have an advantage in estimating the mean and confidence intervals of zinc bioavailability.

Summary: We developed a new econometric model that combines multiple predictors to predict binary outcomes. The model uses the pair-copula construction (PCC) and allows the conditional copula to depend on the conditioning variable in a nonparametric way. We applied this methodology to predict US business cycle peaks 6 months in advance using three leading indicators, and found that it outperformed popular combination models in terms of predictive accuracy measured by the receiver operating characteristic curve. We also evaluated the probability forecasts generated by these models using various diagnostic tools to assess their skill.

Summary: Accurate quantification of microcystins (MCs) in freshwater is essential for environmental monitoring and human health. A novel one-point calibration strategy, using liquid chromatography tandem mass spectrometry (LC-MS/MS), was proposed for the quantitation of eight MCs in freshwater lakes. This strategy showed good performance in selectivity, sensitivity, accuracy and precision, comparable to the traditional multi-sample external calibration curve (MSCC). The strategy allows for sample dilution and removal of blank matrixes, simplifying the workflow and improving throughput.

Summary: Pi-SAR2 is an airborne polarimetric synthetic aperture radar operated by the National Institute of Information and Communications Technology. The polarimetric observation data of Pi-SAR2 have high resolution but lack effective calibration with respect to elevation. In this study, we utilized the AI Bridging Cloud Infrastructure (ABCI) to calibrate the large Pi-SAR2 observation data and report on the calibration, scattering power decomposition, and orthorectification.

Summary: Using the Attouch-The'\ra duality, cycles, gap vectors, and fixed point sets of compositions of proximal mappings are studied, with sufficient conditions given for the existence of cycles and gap vectors. A primal-dual framework establishes an exact relationship between the cycles and gap vectors, and generalized cycle and gap vectors are introduced for cases where classical ones do not exist. Examples are provided to illustrate the results.

Summary: Through analyzing Layer J72S of Unit X in Tabun Cave and other Acheulo-Yabrudian cultural remains, the study reveals the technological and cultural changes during the transition from the Lower to Middle Paleolithic. This suggests that the shift from Lower to Middle Paleolithic may involve a synthesis of old and new technological concepts, rather than a simple displacement process.

Summary: This study investigates the X-ray fluorescence spectroscopy features of micro- and nanosized powder mixtures of copper and nickel, revealing significant differences in calibration curves between nano and micro powders. The study suggests that the XRF measurement error due to particle size is often not taken into consideration, limiting the method's applicability in certain cases. The research demonstrates the potential for expanding the presented approach to other metals and particle sizes.

Summary: This study suggests that adherence to a plant-based paleolithic diet and paleolithic-like lifestyle may reduce the risk of colorectal cancer. These dietary and lifestyle approaches may work by reducing inflammation, oxidative stress, and insulin levels. The study also found a stronger inverse association between the lifestyle score and the risk of colorectal cancer.

Summary: In this study, a detection method was constructed by combining LAMP reaction and CRISPR/Cas12a, which has good specificity and sensitivity. The detection limit of this method is 2.5 CFU/mL and 5 fg/uL, and the detection of artificially contaminated samples can be achieved within 30 minutes. This method allows for more accurate quantification of the template and can be used with visual observation utilizing a UV lamp, making it highly valuable in places with limited medical conditions.

Summary: The concentrations of radiocarbon (C-14) in the oceans differ from those in the atmosphere. Understanding these differences is important for dating samples from the marine environment and studying the carbon cycle. The Marine20 radiocarbon age calibration curve provides a global surface ocean record of radiocarbon from 55,000-0 cal yr BP, accounting for oceanic response to atmospheric C-14 variations and known changes in palaeoclimatic variables. Marine20 is an improvement over the previous Marine13 curve and includes guidelines for calibration and estimating regional oceanic C-14 variation.

Summary: The fossil record of the cave lion suggests a gradual decrease in body size, calling for further investigation. Analysis of cave lion fossils in Ukraine supports the trend of decreasing size, with acceleration during the late stage. The subfossil records of the extant lion in Ukraine most likely represent the Persian lion.

Summary: Understanding the dynamics of dissolved organic carbon (DOC) export from carbon-rich environments is crucial. This study monitored DOC flux from a temperate peatland over 31 months using ultrahigh temporal resolution sampling, and found seasonal and event dynamics in DOC concentration. Discharge was not a reliable predictor of instantaneous DOC concentration, while water temperature showed the most consistent predictability. High-resolution data revealed the complexity of DOC export dynamics and provided insights for future sampling frequency in these environments.

Summary: Radiocarbon dating is widely used in archaeology, particularly in human evolution studies, to determine the timeframe of key events. However, its accuracy is sometimes insufficient to fully comprehend the significant processes of human evolution. This paper reviews the latest method developments in radiocarbon dating ('Radiocarbon 3.0'), aiming for more precise chronologies and a better understanding of major events in recent human evolution. The authors apply these new methods to discuss the dating of the important Palaeolithic site of Bacho Kiro in Bulgaria.

Summary: By studying the ancient mitochondrial genomes of narrow-headed voles from Europe and Asia, the researchers found that the evolution of narrow-headed voles and collared lemings was influenced by climate fluctuations. They also identified time-structured mtDNA lineages in European narrow-headed voles during the Late Pleistocene, which helped explain the drivers of dynamics in steppe- and cold-adapted species.

Summary: Figurative depictions in art emerged about 50,000 years ago and were considered an advanced symbolic behavior. A phallus-like pendant, dating back to around 42,000 years ago, was discovered at the Tolbor-21 archaeological site in Mongolia. This pendant, with its unique characteristics, suggests that hunter-gatherer communities used sexual attributes as symbols early on in their dispersal. Its production coincides with the period of interaction between Homo sapiens and Denisovans, making it a significant find.

Summary: This study examines prehistoric human skeletal remains from the Farneto rock shelter in northern Italy. Despite the fragmented and commingled nature of the remains, radiocarbon analysis provided an accurate dating and revealed intentional interventions and treatment of the corpses. Comparison with other European Neolithic/Eneolithic funerary contexts enhanced the understanding of these complex ritual practices.

Summary: During the Last Glacial Maximum, human populations experienced range contractions that had significant effects on their genetic variation. The genetic ancestry of individuals associated with the post-LGM Magdalenian technocomplex has been linked to pre-LGM Aurignacian groups, but differs from that of the Gravettian in central Europe. Genomic data from southern Spain indicates a direct connection between earlier Aurignacian-associated individuals and post-LGM Magdalenian-associated ancestry, suggesting Iberia as a potential refugium for western European pre-LGM ancestry.

Summary: Palaeo-ice sheets leave behind subglacial lineations, which contain valuable information about the direction of ice flow. The information provided by these lineations is currently underutilised due to the lack of rigorous model-data comparison techniques. This study presents the LALA tool, which allows for a quantitative assessment of ice sheet simulations by comparing simulated and observed lineations. The application of LALA to simulations of the British-Irish Ice Sheet demonstrates its usefulness in identifying the best-fit simulations.
