Summary: A multiplexed assay is developed on a nanoparticle-based laser desorption/ionization mass spectrometry platform for the detection of serum metabolic fingerprints (SMFs) in lung adenocarcinoma (LUAD). A dual modal model, MP-NN, integrating SMFs with protein tumor marker CEA via deep learning, shows superior performance compared to a single modal model. The tri modal model, MPI-RF, integrating SMFs, tumor marker CEA, and image features, demonstrates significantly higher performance in pulmonary nodule classification.

TRIMOON: Two-Round Inconsistency-based Multi-modal fusion Network for fake news detection
Shufeng Xiong, Guipei Zhang, Vishwash Batra, Lei Xi, Lei Shi, Liangliang Liu
Summary: Compared to ordinary news, fake news spreads faster with lower production cost, causing significant social harm. Detecting fake news efficiently and accurately has become a research focus due to these reasons. We propose a Two-Round Inconsistency-based Multi-modal fusion Network (TRIMOON) for fake news detection, consisting of feature extraction, fusion, and classification modules. By performing two-fold inconsistency detection, we effectively filter noise generated during the fusion process. Experimental results demonstrate the superiority of our TRIMOON model over state-of-the-art approaches on Chinese and English datasets.

Nonlinear prediction of functional time series
Haixu Wang, Jiguo Cao
Summary: We propose a nonlinear prediction (NOP) method for functional time series. This method addresses the limitations of conventional approaches, which rely on the stationary or linear assumption of the functional time series and struggle with multivariate functional time series. The NOP method employs a nonlinear mapping for functional data, avoids calculating covariance functions, and enables online estimation and prediction, showing superior prediction performances in simulations and real applications.

Longitudinal Spatial Relationships Between Atrophy and Hypometabolism Across the Alzheimer's Disease Continuum
Jane Stocks, Ashley Heywood, Karteek Popuri, Mirza Faisal Beg, Howie Rosen, Lei Wang
Summary: By analyzing the multimodal neuroimaging relationships between MRI and 18FDG-PET, it was found that in the suspected non-Alzheimer's disease pathology (SNAP) group, there is a spatially overlapping relationship between brain atrophy and hypometabolism at the M-12 timepoint. In the Amyloid Only group, there is a spatially discordant relationship between distributed atrophy and hypometabolism at all time points. In Probable AD subjects, there is a local correlation between bilateral temporal lobes at baseline and M-12 when both modalities are assessed. Across groups, hypometabolism at baseline is correlated with non-local atrophy at M-12. These results support the view that local concordance of atrophy and hypometabolism is the result of a tau-mediated process driving neurodegeneration.

Auditory robustness and resilience in the aging auditory system of the desert locust
Thomas T. Austin, Christian L. Thomas, Ben Warren
Summary: This study investigated the effects of age on the robustness and resilience of auditory system using the desert locust. The researchers found that gene expression changes were mainly influenced by age rather than noise exposure. Both young and aged locusts were able to recover their auditory nerve function within 48 hours of noise exposure, but the recovery of transduction current magnitude was impaired in aged locusts. Key genes responsible for robustness to noise exposure in young locusts and potential candidates for compensatory mechanisms in auditory neurons of aged locusts were identified.
