A 3GPP Perspective on Spectrum Sharing for 5G-to-6G Migration: From LTE-NR DSS Lessons to MRSS Design
arXiv:2604.26853v2 Announce Type: replace Abstract: Dynamic spectrum sharing (DSS) played an important role in the 4G-to-5G transition by allowing 5G new radio (NR) to reuse legacy spectrum without immediate static refarming. Yet practical deployments also exposed the cost of coexistence of NR with long-term evolution (LTE), including overheads, control-channel bottlenecks, neighbor-cell interference, etc. As 6G begins to take shape, spectrum scarcity below 7 GHz is again making 5G-6G...
Hepatic stearoyl-CoA desaturase-1 is specifically suppressed by dextran sodium sulfate but does not influence colitis sensitivity
The delta-9 desaturase stearoyl-CoA desaturase-1 (SCD1) catalyzes the conversion of saturated fatty acids to monounsaturated fatty acids (MUFA) and is highly expressed in liver and adipocytes. Previous studies have demonstrated that treating mice with dextran sulfate sodium (DSS), a chemical inducer of ulcerative colitis, results in severe downregulation of SCD1 in the liver. However, the specific role of hepatic SCD1 in modulating colitis severity, as well as the impact of DSS on SCD1 and...
An Alternative Trajectory for Generative AI
arXiv:2603.14147v2 Announce Type: replace Abstract: The generative artificial intelligence (AI) ecosystem is undergoing rapid transformations that threaten its sustainability. As models transition from research prototypes to high-traffic products, the energetic burden has shifted from one-time training to recurring, unbounded inference. This is exacerbated by reasoning models that inflate compute costs by orders of magnitude per query.
Gut Microbiota Dysbiosis Drives Myocardial Hypertrophy Through GBP2b/GBP1-Mediated Immune Reprogramming and Exosomal Signaling in Chronic Colitis
BACKGROUND: Patients with inflammatory bowel disease (IBD) are at increased risk of cardiovascular disease, yet the mechanisms linking chronic intestinal inflammation to cardiac dysfunction remain poorly understood. IBD is characterized by profound gut microbiota dysbiosis, which we hypothesize drives systemic immune dysregulation and contributes to cardiac dysfunction. A chronic colitis mouse model was used to assess gut microbiota dysbiosis, systemic immune cell metabolism, and cardiac...
Periplasmic detoxification of urate hydroperoxide underpins E. coli survival in the inflamed gut
Uric acid, the final product of purine metabolism in humans, accumulates in blood and tissues at relatively high concentrations as humans lack the enzyme uricase. Under inflammatory conditions, uric acid can be oxidised to yield reactive intermediates. In activated neutrophils, myeloperoxidase (MPO) catalyses the oxidation of uric acid by hydrogen peroxide, leading to the formation of urate hydroperoxide (UH).
Correcting for Global Synonymous Selection Improves the Accuracy of Episodic Positive Selection Inference
The ratio of nonsynonymous to synonymous substitution rates ({omega}) constitutes a fundamental parameter for inferring adaptive protein evolution, predicated upon the assumption that synonymous substitutions are selectively inert. This premise, however, is increasingly untenable given evidence of selection acting on synonymous substitutions, driven by various biological processes such as translational efficiency and mRNA stability. In this study, we demonstrate that unmodelled synonymous...
