Clay weekly context brief for the Quantitative Biology category (ISO week 2026-W31). Clay tracks publications from the Quantitative Biology feed list. Below are recent items from this category, each with its source and a short description of what the publication covers when one is available in the source feed. Recent publications: 1. Multiscale Modelling of Birth-Death Processes Source: q-bio.PE (Populations and Evolution) Link: https://arxiv.org/abs/2601.12712 Many biological systems exhibit multiscale dynamics, where some species occur in high copy numbers while others remain rare. 2. Universal BCI Personalization: One API for Frozen EEG Trunks and Foundation Models Source: q-bio.NC (Neurons and Cognition) Link: https://arxiv.org/abs/2607.22397 Frozen EEG encoders proliferate; per-model fine-tune defaults do not scale. 3. Dynamical compatibility for finite and infinite population models used in genetics Source: q-bio.PE (Populations and Evolution) Link: https://arxiv.org/abs/2512.08783 Finite and infinite population models are frequently used in population dynamics. 4. NUMA balancing hampering performance of spiking network simulations Source: q-bio.NC (Neurons and Cognition) Link: https://arxiv.org/abs/2607.22275 Computing centers today mostly operate conventional CPU- and GPU-based systems, where the direct way of decreasing energy consumption is a reduction in the applications' runtime. 5. From biodiversity modelling to conservation action: a spatial indicator for prioritising tropical forest protection, restoration, and management Source: q-bio.PE (Populations and Evolution) Link: https://arxiv.org/abs/2607.21690 Tropical forests harbour exceptional biodiversity but are increasingly threatened by anthropogenic pressures, making their conservation central to achieving the Convention on Biological Diversity targets. 6. Cycles of Discourse, Speech Dysfluency, and Active Inference Source: q-bio.NC (Neurons and Cognition) Link: https://arxiv.org/abs/2607.22180 Speech is a complex motor and social act. 7. Enumerating monophyletic characters in mathematical phylogenetics Source: q-bio.PE (Populations and Evolution) Link: https://arxiv.org/abs/2607.22097 Grouping species according to their phylogenetic relationships often results in different groups than grouping them according to their shared traits. Sources in this brief: q-bio.NC (Neurons and Cognition); q-bio.PE (Populations and Evolution). Selected 7 of 7 available items for this weekly brief.
