A figure of the JAK-STAT signaling pathway: cytokine binding to a receptor, JAK phosphorylation, STAT dimerization, nuclear translocation, and target gene transcription. Labeled arrows, a clean blue palette, Nature-style typography.

A transformer architecture diagram: input embedding and positional encoding, multi-head self-attention block, feed-forward layers, residual connections and layer norm, ending in a softmax output. Rounded blocks, an attention heatmap inset, muted scientific palette.

A left-to-right experimental workflow for a single-cell RNA-seq study: sample collection, tissue dissociation, droplet capture, library prep, sequencing, and downstream clustering. Labeled stage boxes connected by arrows, editorial journal style.

A reaction mechanism figure for a palladium-catalyzed cross-coupling: oxidative addition, transmetalation, and reductive elimination shown as a catalytic cycle with intermediates and labeled electron arrows. Clean line style on a white background.

A CONSORT-style flow diagram of a three-arm randomized controlled trial: enrollment, randomization into three arms, allocation, follow-up, and analysis, with participant counts at each stage. Boxed steps, top-to-bottom arrows, journal-grade typography.

A labeled schematic of a microfluidic device: inlet channels, mixing junction, reaction chamber, and outlet, with flow-direction arrows and component labels. Clean vector style, soft shadows, scientific palette.
