Synthesizing PET-like images from computed tomography (CT) has been proposed as a way to approximate metabolic information; however, existing approaches either fail to capture region-specific variability or rely on multiple organ-specific models that do not scale to whole-body imaging. In this work, we introduce UniPET, a unified approach for whole-body CT-to-PET translation based on curriculum learning. By progressively incorporating anatomical regions of increasing complexity, UniPET enables a single network to learn coherent morpho-metabolic relationships across different regions. We evaluate UniPET on a public dataset of 900 patients and an external cohort of 579 patients. The model achieves image quality and metabolic consistency comparable to region-specific approaches, while improving over conventional whole-body models and maintaining stable performance under distribution shifts. By capturing region-specific variability within a single model, UniPET provides a promising approach for augmenting CT-based workflows with synthetic metabolic information, with potential applications in screening triage, in low-resource environments where PET is unavailable, and as an additional input for multimodal analysis pipelines.

This article proposes a hash-chained audit-ledger framework to transform public LLM conversations into canonical off-chain units, generate cryptographic commitments using SHA-256 and HMAC-SHA-256, build a lightweight ledger with Merkle roots, and verify integrity against induced tampering. The study integrates three heterogeneous sources, LMSYS-Chat-1M, WildChat, and Chatbot Arena, and produces 3,971,887 auditable units. In the full-corpus HMAC-SHA-256 experiment, the 11,899.55 MiB normalized repository was represented by 1,473.44 MiB of hash-only audit records, 2.03 MiB of ledger block headers, and 380.52 MiB for the operational ledger plus membership structures required for record-level verification. Five induced tampering categories, Merkle and decision-hash integrity, hash-chain linkage integrity, block ordering integrity, membership completeness, and dataset-membership consistency, were detected without false acceptance; a separate clean-ledger baseline validated the untampered ledger with zero error signals. Load experiments showed near-linear growth of mean total pipeline time with respect to the number of audit records. Operational ledger-stage throughput increased across the intermediate workloads but declined at the largest evaluated load, while full record-set verification throughput remained comparatively stable up to 250,000 interactions before decreasing in the 500,000-interaction scenario. This contribution demonstrates that the traceability of decisions generated by LLM can be formulated as a measurable, private, and cryptographically verifiable experimental chain.

Investing in stocks involves various evaluation techniques. However, many of these techniques are restricted to a small set of variables or measurements that are static and historical, limiting their ability to assess the evolving risk-return tradeoff. The objective of this research is to develop a more sophisticated technique that integrates stock evaluation and forecasting by combining traditional financial performance indicators and machine learning time-series forecasting techniques. The result is a system that provides a more organized, simplified, and transparent representation of asset performance and prospective trends. The system provides risk-adjusted performance health scores based on traditional financial metrics such as annualized return, volatility, Sharpe ratio, and drawdown, and supplements this assessment with a Long Short-Term Memory (LSTM) network, which is trained on historical return patterns to generate the predictive signal. Monte Carlo simulation technique is implemented in this work to expect future price paths which, on one hand, are mathematically constrained by the financial limits and, on the other hand, are statistically based on the past distributions. Besides, the framework applies explainable AI methods to interpret the forecasted variations in terms of publicly available market and macroeconomic data, ultimately aiming at opening the \"black box\" to the users and building their trust. The suggested method offers consistent performance evaluation, stable long-term forecasts, and comprehensible insights, which makes it appropriate for decision-support applications in retail investment analysis, according to experimental evaluation using Indian equity and mutual fund data.</p>","PeriodicalId":33315,"journal":{"name":"Frontiers in Artificial Intelligence","volume":"9 ","pages":"1811451"},"PeriodicalIF":6.7,"publicationDate":"2026-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13669191/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149217047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing AI model may struggle to detect the subtle difference due to low resolution fetal movement, which can lead to errors in measurements and diagnosis. In addition, traditional NT measurement methods rely heavily on manual caliper placement, making the process operator-dependent and reducing consistency and automation. To address these challenges, this paper proposes an Enhanced Multi-Scale Spatial Temporal Graph Attention Network (EMSSTGAN) to predict the risk of chromosomal abnormalities in NT. Initially, the input images of NT are pre-processed using feature refinement attention network (FRANet) for denoising and Multi-Scale Attention Retinex Network (MARN) for contrast enhancement. NT detection is then performed by localizing the nuchal translucency region using bounding box annotations, followed by U-Net-based segmentation for precise extraction of the NT area. The Active Contour Model (ACM) is subsequently applied to measure the NT thickness based on boundary geometry. The thickness when compared with threshold values is used to identify the risk of chromosomal abnormalities as low, medium and high.

Existing deep learning-based intrusion detection methods have high identification capability. However, they are also highly susceptible to adversarial attacks, in which even slight perturbations to features can fool the model into misclassification. To address these issues, this study introduced a hybrid deep learning framework. It integrates Convolutional Neural Networks (CNN) and Bidirectional Gated Recurrent Units (BiGRU) to detect diverse types of attacks in real time. CNN extracts spatial interactions to model traffic characteristics, while BiGRU, a recurrent neural network, models temporal dependencies in data flows. This combination enables the model to capture complex spatiotemporal behavioral patterns in network traffic. To address class imbalance, we propose a new Neuro-Evolutionary Resampling Algorithm (NERA). This method uses neural density estimation and evolutionary optimization to generate balanced, noise-filtered training samples. Additionally, a Context-Adaptive Deep Evolutionary Game Framework (CADEGF) is designed to improve resistance to attacks. It does this by simulating interactions between attackers and defenders. It also adjusts detection thresholds using game-theoretic ideas. Experimental results show that this approach achieves high classification accuracy, effectively detects minority classes, and highlights trade-offs between minority-class detection and adversarial robustness, indicating contexts where NERA benefits or harms resilience.
