Characterization of lead and zinc in catchment sediments and their relationship with lead‑zinc mineralization from the Sino–Mongolian border region

The Sino–Mongolian border region is one of the most important metallogenic belts in Central Asia and is an important source of Au, Ag, Pb, Zn, Sn, Cu, and rare metals in southern Mongolia and northern China. The variations in Pb and Zn concentrations and their spatial distribution in the region can indirectly reflect the distribution pattern of mineral resources in the region and provide reference data for the exploration of elements associated with Pb and Zn (e.g., Au, Ag, Cu, and Mn). Moreover, Pb and Zn data are valuable in environmental research because the elements are persistent and potentially toxic heavy metals. Although numerous geological and geochemical surveys of PbZn resources have been conducted in China, the Sino–Mongolian border region remains under studied. Therefore, in this study, we performed an integrated and comprehensive analytical study of single-element and combined PbZn geochemical anomalies. A total of 10,452 catchment sediment samples were collected. Pb concentrations in the samples ranged from 1.90 to 494 mg/kg, while Zn concentrations ranged from 3.00 to 1940 mg/kg. Of these, the median and mean values for Pb were 19.4 mg/kg and 55.0 mg/kg, respectively, while the median and mean values for Zn were 19.9 mg/kg and 58.0 mg/kg, respectively. To characterize the concentration and spatial distribution of Pb and Zn in the study area, we conducted an exhaustive study across several dimensions, considering the geological setting, mineral development, and utilization, and explored the key factors affecting these characteristics. A total of 53 Pb, Zn geochemical anomalies (geochemical province/domain, Pb > 23.1 mg/kg and Zn > 75 mg/kg, > Q85%), including 17 PbZn combined geochemical anomalies, were identified in this study. The PbZn combined geochemical anomalies were mainly concentrated in the Altai region in the west and the Daxinganling region in the east of the study area and are closely related to the distribution of known PbZn deposits. The high-quality geochemical data produced during this study could be an important reference for future mineral exploration work and environmental change studies in the Sino–Mongolian border region.

Multichannel EMG-based gesture recognition utilizing advanced machine learning techniques: A random forest classifier for high-precision signal classification

This research examines how advanced machine learning algorithms can be used to classify multichannel electromyographic (EMG) signals with a high level of accuracy to assist in recognizing hand gestures. The goal is to create a robust and scalable system for gesture-based virtual control using EMG signals with potential applications in assistive technologies, rehabilitation, and human-computer interaction. Data were gathered using a MYO Thalmic bracelet containing eight EMG sensors on thirty-six subjects, and a Random Forest classifier was trained to identify seven distinct types of hand gestures (rest, fist clench, wrist flexion/extension, and radial/ulnar deviations). The machine learning pipeline included extensive preprocessing (i.e., EMG signal normalization and signal feature extraction; root mean square, waveform length, and zero crossing rate) and several hyperparameter tuning procedures to improve model performance. The Random Forest model (100 decision trees) achieved an overall classification accuracy of 98.68%, with a range of accuracies for each class (e.g., 95.2% wrist flexion and 91.8% ulnar deviation) when evaluated using cross-validation (i.e., average F1-score = 0.92, precision = 0.94, recall = .91). Overall, the study provides strong evidence for the effectiveness of ensemble learning methods at analyzing complex, multidimensional EMG signals. The high classification accuracy reported, in particular, demonstrates that the system could function for real-time recognition of hand gestures in a virtual environment. Ultimately, the initial work sets the stage for future exploration of a model that may be integrated with actuation models to control prosthetic limbs, virtual actors/avatars, and robotic devices. By demonstrating a scalable and efficient method of gesture recognition using EMG signals, these early findings enable future pathways and possibilities to design innovative, assistive solutions for digital systems that increase accessibility and interaction for users who are motor impaired or have a limited range of motion.

Lateritic Ni–Co Prospectivity Modeling in Eastern Australia Using an Enhanced Generative Adversarial Network and Positive-Unlabeled Bagging

AbstractThe surging demand for Ni and Co, driven by the acceleration of clean energy transitions, has sparked interest in the Lachlan Orogen of New South Wales for its potential lateritic Ni–Co resources. Despite recent discoveries, a substantial knowledge gap exists in understanding the full scope of these critical metals in this geological province. This study employed a machine learning-based framework, integrating multidimensional datasets to create prospectivity maps for lateritic Ni–Co deposits within a specific Lachlan Orogen segment. The framework generated a variety of data-driven models incorporating geological (rock units, metamorphic facies), structural, and geophysical (magnetics, gravity, radiometrics, and remote sensing spectroscopy) data layers. These models ranged from comprehensive models that use all available data layers to fine-tuned models restricted to high-ranking features. Additionally, two hybrid (knowledge-data-driven) models distinguished between hypogene and supergene components of the lateritic Ni–Co mineral systems. The study implemented data augmentation methods and tackled imbalances in training samples using the SMOTE–GAN method, addressing common machine learning challenges with sparse training data. The study overcame difficulties in defining negative training samples by translating geological and geophysical data into training proxy layers and employing a positive and unlabeled bagging technique. The prospectivity maps revealed a robust spatial correlation between high probabilities and known mineral occurrences, projecting extensions from these sites and identifying potential greenfield areas for future exploration in the Lachlan Orogen. The high-accuracy models developed in this study utilizing the Random Forest classifier enhanced the understanding of mineralization processes and exploration potential in this promising region.

Identification of Key Genes Involved in Seed Germination of Astragalus mongholicus

Seed germination is a fundamental process in plant reproduction, and it involves a series of complex physiological mechanisms. The germination rate of Astragalus mongholicus (AM) seeds is significantly lower under natural conditions. To investigate the key genes associated with AM seed germination, seeds from AM plants were collected at 0, 12, 24, and 48 h for a transcriptomic analysis, weighted gene co-expression network analysis (WGCNA), and machine learning (ML) analysis. The primary pathways involved in AM seed germination include plant-pathogen interactions and plant hormone signaling. Four key genes were identified through the WGCNA and ML: Cluster-28,554.0, FAS4, T10O24.10, and EPSIN2. These findings were validated using real-time quantitative reverse transcription PCR (qRT-PCR), and results from RNA sequencing demonstrated a high degree of concordance. This study reveals, for the first time, the key genes related to AM seed germination, providing potential gene targets for further research. The discovery of N4-acetylcysteine (ac4C) modification during seed germination not only enhances our understanding of plant ac4C but also offers valuable insights for future functional research and application exploration.

AI-powered simulation-based inference of a genuinely spatial-stochastic gene regulation model of early mouse embryogenesis.

Understanding how multicellular organisms reliably orchestrate cell-fate decisions is a central challenge in developmental biology, particularly in early mammalian development, where tissue-level differentiation arises from seemingly cell-autonomous mechanisms. In this study, we present a multi-scale, spatial-stochastic simulation framework for mouse embryogenesis, focusing on inner cell mass (ICM) differentiation into epiblast (EPI) and primitive endoderm (PRE) at the blastocyst stage. Our framework models key regulatory and tissue-scale interactions in a biophysically realistic fashion, capturing the inherent stochasticity of intracellular gene expression and intercellular signaling, while efficiently simulating these processes by advancing event-driven simulation techniques. Leveraging the power of Simulation-Based Inference (SBI) through the AI-driven Sequential Neural Posterior Estimation (SNPE) algorithm, we conduct a large-scale Bayesian inferential analysis to identify parameter sets that faithfully reproduce experimentally observed features of ICM specification. Our results reveal mechanistic insights into how the combined action of autocrine and paracrine FGF4 signaling coordinates stochastic gene expression at the cellular scale to achieve robust and reproducible ICM patterning at the tissue scale. We further demonstrate that the ICM exhibits a specific time window of sensitivity to exogenous FGF4, enabling lineage proportions to be adjusted based on timing and dosage, thereby extending current experimental findings and providing quantitative predictions for both mutant and wild-type ICM systems. Notably, FGF4 signaling not only ensures correct EPI-PRE lineage proportions but also enhances ICM resilience to perturbations, reducing fate-proportioning errors by 10-20% compared to a purely cell-autonomous system. Additionally, we uncover a surprising role for variability in intracellular initial conditions, showing that high gene-expression heterogeneity can improve both the accuracy and precision of cell-fate proportioning, which remains robust when fewer than 25% of the ICM population experiences perturbed initial conditions. Our work offers a comprehensive, spatial-stochastic description of the biochemical processes driving ICM differentiation and identifies the necessary conditions for its robust unfolding. It also provides a framework for future exploration of similar spatial-stochastic systems in developmental biology.

Geology of Mudstones Atop the Sangonghe Formation, Shuixigou Group, Turpan‐Hami Basin: New Insights and Their Implications for Petroleum Geology

ABSTRACTAs the exploration of deep‐seated oil and gas resources in the Turpan‐Hami Basin intensifies, there is an urgent need to thoroughly depict the geological characteristics of newly uncovered, underexplored strata in sub‐sag centers. This study undertakes the inaugural systematic geochemical analysis of mudstones atop the Sangonghe Formation, including palynological identification, maceral identification, biomarker analysis, total organic carbon (TOC) analysis, and pyrolysis. The findings reveal that the mudstone sequence, as the target layer, was deposited in a warm and moist paleoclimate and a weakly reducing to weakly oxidising saline water environment, fostering the growth of prolific algae and bacteria, thus ensuring substantial foundational materials for source rock formation. The organic matter in the mudstone sequence displays pronounced laminar accumulation. Despite the overall modest abundance, the organic matter features notable hydrocarbon‐generating potential per unit of organic carbon and favourable types. Humic‐sapropelic kerogens (type II1) are found in the mudstones, with organic matter generally reaching a mature to highly mature stage. These characteristics establish the mudstones as effective source rocks, furthermore, the hydrocarbon expulsion in the Xishanyao Formation precedes that of the Sangonghe Formation and that both formations constitute a sequential process in terms of hydrocarbon generation and expulsion timing and hydrocarbon contribution. Reanalyzing this mudstone sequence not only revises prior geological understanding of it as direct cap rocks, but also facilitates the reclassification of deep‐seated strata into three distinct petroleum systems. Centered around this source rock layer, dual modes, namely the “lower‐source rock and upper‐reservoir” and the “ lower‐reservoir and upper‐source rock” modes can be formed. These new insights will offer profound implications for hydrocarbon resource evaluation and future hydrocarbon exploration endeavours in the Shuixigou Group within the Taibei sag.

STEM-14. INTEGRATED ANALYSIS OF GLIOBLASTOMA PROGENITOR SUBTYPES REVEALS A TUMOR-DERIVED STEM CELL POPULATION WITH NEURAL AND VASCULAR POTENTIAL

Abstract Glioblastoma (GBM) exhibits a vast heterogeneity in cell types and states. Recent research highlights the reactivation of neurodevelopmental programs in GBM, contributing to this heterogeneity and, ultimately, therapy resistance. To characterize the landscape of progenitor cell types in human primary GBM, we compiled a meta-atlas of single-cell transcriptomes from seven published studies. Using a novel bioinformatic method for gene program analysis, we derived GBM gene expression meta-modules represented across multiple tumors. Our analyses validated previously described GBM gene programs and revealed novel tumor progenitor subtypes. Among these subtypes, we identified a tumor-derived stem cell population exhibiting a mixed vascular identity and transcriptional programs reminiscent of neural stem cells, which we identified as a putative neurovascular progenitor (NVP). To our knowledge, this population has not been previously described in GBM. We validated the existence of NVPs in situ using immunofluorescence from primary patient GBM samples. We then performed an enrichment for NVPs using fluorescence-activated cell sorting direct from patient tumors, followed by single-cell RNA sequencing. Examination of data from traditional model systems, including gliomaspheres and mouse GBM models, confirmed the preservation of NVP identity across systems. In vivo analysis of NVPs in multiple mouse models of GBM elucidate the influence of NVPs on GBM cell type composition, highlighting their role as multipotent progenitors. Finally, we utilized single-cell lineage barcoding to trace the progeny of patient-derived NVP cells in a novel organoid transplantation model, revealing NVP differentiation into vascular-like and neural-like cells. These data indicate that NVP cells play crucial roles in tumor plasticity and may represent a valuable therapeutic target for future exploration.

Patch Correctness Assessment: A Survey

Most automated program repair methods rely on test cases to determine the correctness of the generated patches. However, due to the incompleteness of available test suites, some patches that pass all the test cases may still be incorrect. This issue is known as the patch overfitting problem. Overfitting problem is a longstanding problem in automated program repair. Due to overfitting patches, the patches obtained by automated program repair tools require further validation to determine their correctness. Researchers have proposed many methods to automatically assess the correctness of patches, but no systematic review provides a detailed introduction to this problem, the existing solutions, and the challenges. To address this deficiency, we systematically review the existing approaches to patch correctness assessment. We first offer a few examples of overfitting patches to acquire a more detailed understanding of this problem. We then propose a comprehensive categorization of publicly available techniques and datasets, examine the commonly used evaluation metrics, and perform an in-depth analysis of the effectiveness of the existing models in addressing the challenge of overfitting. Based on our analysis, we provided the difficulties encountered by current methodologies, alongside the possible avenues for future research exploration.
