arXiv The work adapts the WUSH transform, originally for weight-activation quantization, to the KV cache of grouped-query attention: calibration data builds separate key and value transforms per KV head (the value transform folded into the weights, the key transform applied after RoPE), the transform is shown to be near-optimal among sensitivity-balanced transforms for the QuEST quantizer, and end-to-end evaluation in SGLang with OSCAR-style percentile-clipped affine quantization gives 2-bit WikiText-2 perplexity of 10.51 on Qwen3-8B versus OSCAR's 13.74, with the 8B model scoring higher than OSCAR on AIME 2025, MATH-500, GPQA Diamond, and LiveCodeBench v6.

Cohere Labs Cohere introduces RCP-nDCG@10, a retrieval evaluation methodology in which a calibrated AI judge grades every retrieved document against the same explicit relevance rubric and combines rubric answers with group-wise comparisons and calibration, so relevant documents absent from the answer key can still earn credit; in a blind study with 46 annotators, 273 queries and 289 head-to-head contests, reviewers sided with RCP-nDCG 70% of the time where the two metrics named different winners, and across all contests RCP-nDCG matched reviewer preference 77% of the time versus 52% for conventional nDCG, with the gain driven mainly by crediting relevant documents the answer key missed (19 percentage points).

Natural Sciences and Applied Technology Using 17,049 e-commerce transaction records from 5,000 customers observed between January 2023 and February 2024, the study built a customer-level customer lifetime value (CLV) prediction pipeline with 33 modelling attributes and compared ridge-based Linear Regression, Random Forest, Gradient Boosted Trees and a feed-forward Neural Network under a common 10-fold cross-validation design in Altair AI Studio (RapidMiner), then converted predicted value into three actionable segments of 2,763 low-value, 1,252 medium-value and 985 high-value customers.

The FASEB Journal In KRAS-mutant and KRAS wild-type pancreatic ductal adenocarcinoma cells (PANC-1, BxPC-3) and a PANC-1 subcutaneous xenograft model, this study shows that the natural polyphenol ellagic acid (EA) combined with the GPX4 inhibitor RSL3 synergistically reduces cell viability and suppresses tumor growth by activating p38 MAPK and upregulating Keap1 to inhibit the Nrf2/HO-1 antioxidant axis, amplifying ferroptotic hallmarks such as iron accumulation, lipid peroxidation, and GPX4 downregulation, with Fer-1 rescuing viability while apoptosis, necroptosis, and autophagy inhibitors do not.

bioRxiv The study introduces VRPTR, a three-dimensional encoder-decoder combining a compressed Transformer bottleneck, variational latent sampling, and multiscale skip connections, trained on 360 healthy adults from the WU-Minn Human Connectome Project and evaluated on 40 held-out participants for the story-versus-math language contrast, achieving mean voxel-map Pearson r=0.642 and Dice AUC=0.519, exceeding compact volumetric BrainSurfCNN-like and SWIFUN-like comparators by Δr=0.0376 and 0.0335 respectively, while raw 95% intervals covered only 4.7% of observed values and five-fold calibration within the held-out cohort raised coverage to 94.8%.
