Seven KNN hyperparameter tuning strategies compared across 15 datasets: PSO ranks best overall but significantly beats only random search

Under a nested cross-validation framework, this study compared seven hyperparameter tuning strategies for classical KNN over a mixed search space comprising an integer neighborhood size k, a categorical distance metric, and a continuous Minkowski exponent p—grid search, random search, Bayesian optimization, genetic algorithm, surrogate optimization, particle swarm optimization (PSO), and grey wolf optimizer—evaluating them on 15 public classification datasets using accuracy, macro AUC, cross-validation loss, cross-entropy loss, and runtime, and found that PSO achieved the best overall mean rank but held a statistically significant advantage only over random search under Holm-corrected Wilcoxon signed-rank tests.

Leakage-aware ML predicts MOF drug loading and cell viability at in-domain R² of 0.557 and 0.774, but R² turns negative when whole publications are held out

Using data reconstructed from Wang et al.'s supplementary tables, this study built 161 loading-capacity observations with 110 descriptors and 444 cell-viability observations with 25 descriptors, optimized histogram-based gradient boosting regression (HGBR) and partial least squares regression (PLSR) with differential evolution under five-fold grouped cross-validation, and constrained exact duplicate records to the same partition to prevent information leakage; on the duplicate-safe 20% holdout HGBR was strongest for cell viability (R² = 0.774, RMSE = 11.655 percentage points, MAE = 8.153, AARD = 16.69%) while PLSR was best for loading capacity (R² = 0.557, RMSE = 0.345 g/g, MAE = 0.210 g/g), yet holding out entire source publications drove all R² values negative (viability −0.391 and −0.

Network meta-analysis of 10 phase III trials and over 8,000 advanced gastric cancer patients ranks trastuzumab and tislelizumab highest for delaying quality-of-life deterioration

This network meta-analysis pooled 10 phase III randomized controlled trials with over 8,000 patients with unresectable advanced gastric cancer, ranked first-line immune checkpoint inhibitors and targeted agents by SUCRA on time to deterioration across EORTC QLQ-C30, EORTC QLQ-STO22 and EQ-5D domains, and used an exploratory minimum distance criterion to integrate overall survival with health-related quality of life, finding that trastuzumab (HER2-positive population) and tislelizumab (largely biomarker-unselected population) ranked most favorably across most quality-of-life domains, while the composite metric remains exploratory, lacks uncertainty estimates, and should not serve as primary evidence for clinical decision-making.

Splitting the East China Sea into clear and turbid regimes by nLw555, a CatBoost reconstruction finds the turbid zone is a weak CO2 source and that conventional models overestimate the ECS sink by about 46%

Using a threshold of nLw555 = 1.5 mW cm-2 µm-1 sr-1 from MODIS to separate the East China Sea into Clear Water (CW) and Turbid Water (TW), this study reconstructed surface pCO2 for 2003–2023 with a CatBoost model that treats water type as a categorical input alongside multi-spectral satellite variables, achieving independent-test accuracy of R2 = 0.86 and RMSE = 16.55 µatm and cutting TW RMSE by up to about 81% relative to conventional models; the 21-year climatology gives CW 361.2 µatm and TW 415.1 µatm, with TW acting as a weak net source (+0.50 Tg C yr-1) driven by positive non-thermal anomalies (+28.09 µatm), implying conventional models overestimate total ECS carbon uptake by roughly 46% (about 4.04 Tg C yr-1).

A game between two hybrid pension managers under jump-diffusion liabilities: competition pushes risk-taking to K=(μ−r)/σ², while own liability jumps lower welfare and the rival's jumps raise it

The study models two competing hybrid DC pension fund managers as a stochastic differential game in which liability risk follows a jump-diffusion process with truncated exponential jump amplitudes and the exact asset-to-liability ratio formulation is used, and it derives closed-form Nash equilibrium portfolio strategies and value functions via Hamilton–Jacobi–Bellman dynamic programming, finding that equilibrium weights are independent of liability jump parameters, reduce to K=(μ−r)/σ² and are independent of both managers' risk aversion in the symmetric liability-correlation case, that competition strictly amplifies risk-taking relative to the single-agent benchmark, and that a manager's own liability jumps reduce welfare while the competitor's jumps improve it.

Across 2,907 FAERS reports on methotrexate in pediatric leukemia, nervous system disorders gave the strongest signal, febrile neutropenia was the most reported PT, and 72.1% of evaluable onsets fell within 30 days

Drawing 2,907 FAERS reports (Q1 2018–Q1 2025) in which methotrexate was the primary suspect drug for pediatric leukemia, the study applied four disproportionality methods (ROR, PRR, BCPNN, MGPS) with sex and five age strata and fitted time-to-onset with a Weibull distribution, finding that nervous system disorders had the largest SOC-level report count (1,691 cases, ROR 2.87, 95% CI 2.69–3.05), that febrile neutropenia led at the PT level (446 reports) followed by neurotoxicity (238) and mucosal inflammation (170), that confusional state, dehydration, and epistaxis showed greater reporting disproportionality in males, that six PTs were detected in all five age strata, and that 681 of 944 evaluable onset reports (72.

This Perspective proposes three principles—substrate proportionality, temporal defeasibility, and auditable continuity—so memory-enabled LLM agents can decide which substrate a new piece of evidence belongs in, or whether to write nothing at all.

This Perspective addresses LLM agents that accumulate state across sessions, tools, users, and changing environments, and proposes a framework of controlled knowledge updating: treating an update as a decision to select the least invasive substrate sufficient for the claim's scope—among context, external memory, model parameters, activation states, and tool or workflow definitions—including the option not to write persistent state, organized by three principles (substrate proportionality, temporal defeasibility, auditable continuity) and motivating evaluation criteria covering update selection, temporal consistency, interference, reversibility, efficiency, and robustness, together with a four-phase minimal benchmark unit.

RNASeek uses a 1.6B-parameter cross-phyla transcriptomic model for RNA function prediction and GRPO-guided design, yielding ribozymes at wild-type activity and 3′ UTRs beyond the training data

The authors present RNASeek, a 1.6-billion-parameter generative foundation model built on a DeepSeek architecture and trained on a cross-phyla transcriptomic corpus, using natural-language tokens for conditional prediction and sequence design; it captures species-specific transcript features and intron–exon boundaries in a zero-shot setting, can be fine-tuned to predict ribozyme self-cleavage activity and viral mRNA stability while revealing interpretable features such as loop flexibility, stem stability, and AU-rich motifs, and these functional predictors then serve as reward models for GRPO updates to the generation policy, producing faster-cleaving ribozymes and stability-enhancing 3′ UTRs under user-specified IUPAC constraints, with experimentally validated generated ribozymes reaching

Greek trisyllabic word list developed: 40 words retained after testing 20 children aged 6 to 12 for speech recognition threshold

Addressing the gap in Speech Recognition Threshold (SRT) materials for Greek-speaking school-aged children (6 to 12 years), this study selected words on four criteria—syllabic structure (trisyllabics), age-appropriate vocabulary familiarity, phonemic differentiation, and homogeneity in audibility—recorded and processed them per ISO 8253-3:2022, had 20 children take part in the word homogeneity evaluation, determined for each word the presentation level needed for 50% correct recognition, and measured recognition rates across intensities to locate the steepest rise of the Performance-Intensity (PI) function between 20% and 80% recognition; it found that words homogeneous in recognition rate are not homogeneous in recognition threshold and vice versa, so only words within +1 Standard Deviati
