A survey of deep multivariate time-series models with an empirical reproducibility audit

Multivariate time series (MTS) analysis is increasingly important for extracting insights from complex, interdependent temporal data in domains such as healthcare, finance, and industrial monitoring. Recent advances in deep learning have significantly improved MTS modeling; yet,...

Global spatiotemporal variability of chlorophyll a and environmental drivers revealed by empirical orthogonal function analysis

Abstract Chlorophyll a (Chl a ) is a key indicator of phytoplankton biomass and marine primary productivity, linking ocean ecosystem change to biogeochemical cycling and climate. Understanding the environmental controls on long‐term Chl a variability is therefore essential. Here,...

Optimization of Poly-γ-Glutamic Acid Production by Moderate Electric Field-Assisted Fermentation in a Haematococcus pluvialis-Based Medium

Moderate electric field (MEF) fermentation was investigated as a nonthermal stress strategy to enhance the formation of extracellular polymeric substances (EPS; mucilage) by Bacillus subtilis HA in a Haematococcus-based medium. Response surface methodology (RSM), combined with a...

In-Situ anchoring of amorphous NixB nanoparticles onto Nb2CTx MXene nanosheets for high-performance asymmetric supercapacitors

An amorphous nickel boride/niobium carbide MXene (Ni x B/Nb 2 CT x ) composite was designed and synthesized via a combined HF-assisted etching and in-situ chemical reduction strategy. The uniform anchoring of 0D Ni x B nanoparticles within the multilayered Nb 2 CT x nanosheets le...

Brachyspira hyodysenteriae detected in a dog with acute haemorrhagic diarrhoea: a case report

Abstract Background Brachyspira hyodysenteriae is a well-known pathogen of swine dysentery, a severe mucohaemorrhagic colitis in pigs. While several Brachyspira species are reported in dogs, natural Brachyspira hyodysenteriae detection in dogs is extremely rare. This case report...

Halophyte-derived bacterial SynComs improve soybean growth under salinity stress

Abstract Rhizosphere microbes with plant growth-promoting (PGP) traits can sustain crop productivity, yet endophyte-derived synthetic communities (SynComs) from hypersaline environments remain underexplored. We hypothesize that halophyte endophyte-derived SynComs improve stress t...

KiGEP: a quantitative algorithm for calculating human kidney similarity and nephrotoxicity in human kidney organoids

Kidney organoids (KOs) are being actively developed and used as models for evaluating nephrotoxicity, which is an important process during drug development. To evaluate human pluripotent stem cell-derived KOs, various lineage markers have been used to confirm KO differentiation v...

Enhanced salivary correlation between Streptococcus mutans and herpes simplex virus-1 in oral squamous cell carcinoma: a case-control study

Streptococcus mutans modulates local immune responses in the oral mucosa and has been implicated in oral squamous cell carcinoma (OSCC) pathogenesis. Emerging evidence suggests that certain oral bacteria can influence viral infections through immune modulation. This case-control...

Conformal prediction for spatial data with GAM-trend adjustment

Reliable uncertainty quantification for spatial prediction remains a central challenge due to the sensitivity of classical geostatistical methods, particularly kriging, to assumptions of stationarity, Gaussianity, and correctly specified covariance models.This study presents a pr...
