**A**: The advantages of the GNN architecture are well illustrated by the results for chignolin.
A previous machine-learning study of chignolin identified two slow CVs, one for the folding-unfolding transition and one distinguishing competing folded states[63]. Our VAMPnets appear to recover these two CVs (Figures 3 and S3; results shown are with SubMixer), distinguishing folded and unfolded states with CV 1 and four folded states with CV 2**B**: CV 2 distinguishes the folded states by the configurations of Thr6 and Thr8 side chains, which can each occupy two rotamers, yielding four possible folded states. These side chain dynamics could not be detected by VAMPnets that take backbone internal coordinates as inputs, as is common, or even GNNs limited to backbone atoms (Bonati, Piccini, and Parrinello [63] included distances to side chain atoms and then manually curated the inputs).**C**: To understand the physical differences between the folded states, we plot CVs 1 and 2 as functions of the fraction of native contacts and the χ1subscript𝜒1\chi_{1}italic_χ start_POSTSUBSCRIPT 1 end_POSTSUBSCRIPT side chain dihedral of Thr6 or Thr8 (Figure 4).

**A**: What might you do? If you start very early and have plenty of time, you might prefer to walk all the way. If you have very little time, you might need to run all the way**B**: But if you had an intermediate amount of time, what might you do? Here, we perform this experiment for two long distances over 800 meters, and show that humans systematically use a mixture of walking and running when there is an intermediate amount of time. That is, we show that for such overground tasks, there is not a sharp gait transition speed below which walking is preferred and above which running is preferred. Having this mixture of walking and running instead of a sharp gait transition speed is energy optimal [1, 22, 23], and was earlier observed over short distance tasks in humans [1], so the primary experimental contribution of the current study is its demonstration over much longer distances.

For instance, the Umberger et al model [27] predicted roughly 7% of experimentally measured cost for an isomeric task involving tracking sinusoidal forces [28]. The models developed from in vivo human experiments have either no prediction for isometric tasks as they were derived with terms specific to non-isometric tasks [29, 30, 31], considered only force level changes but not time series changes [32, 8] or only time series changes but not force level changes [33, 28].

**A**: Second, there is a separation of mutational time scales: site complexity changes take place at a much lower rate than recognition site and target mutations (ν≪μmuch-less-than𝜈𝜇\nu\ll\muitalic_ν ≪ italic_μ). Third, because selection on the recognition function depends only the binding affinity phenotype ΔGΔ𝐺\Delta Groman_Δ italic_G, the model does not introduce any explicit fitness benefit of sequence complexity. Nevertheless, complexity can emerge as a collateral of selection for function in a non-equilibrium dynamical pathway – an evolutionary ratchet. We will first characterize the complexity of stationary states in different parameter regimes of the evolutionary model, then derive specific dynamical pathways towards these states.**B**: Three model features turn out to be crucial for what follows. First, the sequence mutation dynamics does not introduce any bias towards higher complexity**C**:
Clearly, the minimal evolutionary model is a broad approximation to the evolutionary dynamics of any specific receptor-target interface. The model neglects many details of actual molecular evolution processes that are not important for conclusions of this paper

**A**: A strong core-periphery structure implies the system has a set of dominant, highly interconnected basins of attraction (the core) where transitions are frequent and stable**B**: The peripheral basins of attraction are less frequently visited, with transitions mainly leading back to the core**C**: This structure indicates that the system tends to remain within the core’s stable dynamics and only occasionally explores the less stable, transient states represented by the periphery. In contrast, in the syncopation condition, the average dwelling time and motif length decreased, betweenness centrality declined, and average shortest path length increased. This indicates that stronger coupling in syncopation enhances the stability of a larger set of states and distributes the probability flow more broadly, reducing the dominance of core nodes and creating a more distributed but less efficient flow.

Relationships between living things and their natural environments are the only focus of ecological research. Ecological systems are developed by their interactions, which are important for population ecology. In nature, resources are frequently distributed extensively over the ecosystem**B**: Therefore, organisms are diffusive throughout the environment because they must locate food and survive. Since trophic interactions are greatly influenced by species movement, different spatial patterns in nature have evolved. Several studies have demonstrated that aquatic and terrestrial populations may form patterns [31, 32]**C**: Spatial patterns are shaped by many causes, including deterministic processes, species growth, mobility, stochastic processes, environmental changes, and more. Because species interact across habitats, patterns are common in the ecological system [33, 34]. Self-organized spatial patterns are the result of a deterministic process in interacting organisms. The spatio-temporal predator-prey model is given as follows:

When GABA binds to these receptors, the channel opens, allowing chloride ions to enter the neuron**C**: This influx of chloride ions causes hyperpolarization of the neuronal membrane, making it less likely for the neuron to fire an action potential.

**A**: In extreme cases this mismatch in individual fitness and population viability can lead to evolutionary suicide, where viable populations adapt in a way that they can no longer persist (Parvinen, 2005; Ferriere and Legendre, 2013). Conversely, because of the interplay between evolutionary and ecological processes (such as fluctuation in host densities), parasites should evolve toward decreased virulence (Lenski and May, 1994). Moreover, co-infection of hosts (singly infected cells remain susceptible and can be infected again) (Alizon, 2013) can result in feedback loops between the rate at which susceptible individuals acquire a disease (the force of infection) and virulence: when double infections are common increased virulence is favored; however, increased pathogen virulence decreases the force of infection, favoring decreased virulence once more (van Baalen and Sabelis, 1995).
**B**: Still, since selection acts first and foremost on the level of individuals, traits which produce more offspring should generally increase in frequency. This suggests tensions between selective pressures on individual phages and the viability of the phage population overall**C**: A natural expectation is that larger burst sizes would benefit the phage population.

These studies have contributed to the development of both linear and nonlinear models that map stimuli to brain activity from fMRI signals. Previous work focused on e.g**C**: enhancements in network scaling and uncovering associations between brain activity and specific auditory and semantic processing tasks (Caucheteux and King, 2022). However, limitations in the temporal resolution of fMRI, which are particularly relevant in speech decoding due to the high-frequency content of the stimuli, have led researchers to explore MEG data collected during exposure to auditory stimuli.

**A**: In a homogeneous attractant environment, after a large number of runs and tumbles the net displacement of the cell is zero. But in presence of an attractant concentration gradient, runs in the favorable direction are extended and those in the opposite direction are shortened, giving rise to a chemotactic drift [27, 28, 29, 30, 31].**B**:
In this work, we use reinforcement learning to study a model that has been motivated by the phenomenon of bacterial chemotaxis [15, 16, 17]. Certain bacteria like E.coli, S.typhimurium, B.subtilis are known to show chemotaxis where they can move along a chemical gradient in their environment [18, 19, 20]**C**: When these microorganisms experience concentration gradient of an attractant chemical in their surroundings, they show a tendency to migrate towards regions of higher attractant concentration [21, 22, 23, 24]. This migration happens via run-and-tumble motion, which is characterized by persistent movement along a particular direction (run), punctuated by abrupt change of direction (tumble) [25, 26]

**A**: Additionally, learning discrete states independently becomes prohibitively costly when estimating dynamics for a population that contains multiple independent subgroups. In this scenario, SLDS learns distinct systems for each potential combination of dynamics**B**: For example, switched systems often learn approximate dynamics which have discontinuities along the boundaries of the switches. This can be well suited to capturing sudden changes in dynamics, but may not accurately represent smooth transitions between dynamical modes.
Approximating smooth transitions requires increasing the number of linear states available to capture intermediate stages**C**: However, the number of possibilities grows exponentially as the number of subgroups and dynamical modes increases, rendering it combinatorially impractical. Moreover, this challenge is compounded during inference where the learned systems are rigid and cannot adapt to capture similar dynamics. Instead, SLDS must learn new distinct states to accurately represent subtle variations of similar dynamics. For a fixed number of parameters, dLDS improves the expressivity of the switching linear approach by offering a controlled way to flexibly modify and reuse learned linear regimes.

By providing a simultaneous handle on the multiple timescales that govern behavior such as cruising and wandering, differential modulation of speed and egocentric direction preference, our approach sets the stage for dissecting the underlying brain circuits for navigation in a transparent vertebrate brain. Along with the serotoninergic modulation of motor activity mentioned previously, we can dissect how multiple brain regions function together to give rise to this hierarchy of timescales in behavior**B**: The hindbrain oscillator, also called anterior rhombencephalic turning region has been identified as one brain region that confers a persistence of the left/right steering in the larval zebrafish (dunn2016brain, wolf2017sensorimotor). We hypothesize that the interplay of this region with the mesencephalic locomotor region (MLR, carbo2023mesencephalic), the nucleus of the medial longitudinal fasciculus (wang2014selective, berg2023brainstem), projecting onto the reticular formation (orger2008control, carbo2023mesencephalic) could explain the dynamics we uncover**C**: In particular, the modulation of the MLR by dopamine released from posterior tuberculum (carbo2023mesencephalic) could explain the long-lived persistence of cruising behaviors. There is already some evidence for this in mice, where dopamine release has been associated with long time scale (seconds to minutes) persistence of motor sequences (markowitz2023spontaneous).

**A**: Notably, we observed that smaller initial gains can paradoxically hinder learning. This result is explained by our analysis of the Lyapunov exponent, which is crucial for the stability and information propagation within the network. We found that smaller initial gains resulted in larger deviations of the Lyapunov exponent from zero before training, indicating a greater challenge in achieving the balanced dynamical properties necessary for effective learning**B**: To address this challenge, we brought the gradient flossing method into the biologically plausible learning framework, leading to performance improvement for suboptimal initial weight magnitudes. Overall, these findings provide insights into how variations in initial connectivity may influence learning in neural circuits, offering predictions that can guide future experimental work. Additionally, these findings have practical implications for the design of neuromorphic chips, where optimizing initial weight configurations could enhance the efficiency and effectiveness of energy-efficient biologically plausible learning algorithms.
**C**: This study highlights the role of initial weight magnitude in shaping the learning dynamics of biologically plausible rules, predicting its importance in neural circuit learning. While the influence of initial connectivity on learning has been extensively explored in the realm of backpropagation-based learning, our work is novel because it extends this inquiry to biologically plausible settings. Our findings demonstrate that, similar to backpropagation through time (BPTT), the choice of initial weight magnitude in e-prop — a biologically plausible learning rule — has a profound impact on learning performance

These arguments and predicates may align with existing human-like categories or form entirely novel “alien-like” categories that could represent statistical constructs [11] or “polysemic concepts” [14, 53] not directly relatable to human cognitive categories.

**A**: Seasonal antigenic prediction, particularly for influenza A H3N2, has benefited from machine learning approaches that help forecast viral evolution, supporting timely vaccine updates [304]. Finally, phylogenetic analyses have identified optimal influenza virus candidates for seasonal vaccines, underscoring the significance of LLMs in guiding vaccine development against anticipated strains [316].
**B**: Additionally, antigenic prediction plays a crucial role in designing effective influenza vaccines, especially for rapidly evolving strains. Statistical analyses of antigenic similarity, such as those conducted for influenza A (H3N2), highlight the potential of machine learning models in mapping antigenic drift and optimizing strain selection for seasonal vaccines [313]**C**: Moreover, cellular correlates of protection identified through human influenza virus challenges have advanced our understanding of immune responses to oral vaccines, demonstrating the applicability of machine learning models in immune signature identification [314]. Blood inflammatory biomarkers have also been analyzed to differentiate COVID-19 from influenza cases, showcasing the predictive power of LLMs in clinical biomarker differentiation [315]

**A**: We are interested in what would happen if grazers and browsers are added into a purely competitive environment among plants and whether trees, grass, grazers, and browsers can coexist. Therefore, we focus on the co-existence steady state of four species (which is unique) in the proposed savanna system (1.1) and study related traveling wave solutions, which may provide important information about the transition dynamics between the co-existence state and other steady states**B**: To obtain our results, we employ the upper-lower solution method widely used in related studies. However, due to the absence of linear reaction terms in our herbivore equations for G𝐺Gitalic_G and B𝐵Bitalic_B, the usual form of exponential functions for the lower solutions does not work in our case. To overcome this difficulty, we introduce Gaussian-like functions at one end of the real line domain and successfully find suitable lower solutions for our problem.**C**: We demonstrate the existence of two types of traveling waves, the waves transitioning
from the extinction state to the co-existence state and the waves from a grass-vegetation state (where only grass and grazers exist) to the co-existence state. Our results indicate that under suitable conditions, the co-existence state of four species may be dominant or more stable compared to other steady states in the sense of wave dynamics

Each sub-layer is followed by a residual connection and layer normalization to normalize input values for all neurons in the same layer [27], as illustrated in Fig 1.

**A**: Clinical Trial Matching**B**: Many studies have focused on learning patient retrieval and enrollment information for predicting individual patient outcomes within clinical trials, rather than making overall predictions about trial success.
Doctor2Vec [1] learns representations for medical providers from EHR data, and for trials from their descriptions and categorical information, in order to address data insufficiency issues such as trial recruitment in less populated countries**C**: DeepEnroll [28] encodes enrollment criteria and patient records into a shared latent space for matching inference. COMPOSE [7] encodes structured patient records into multiple levels based on medical ontology and used the eligibility criteria embedding as queries to enable dynamic patient-trial matching. In contrast, our work focuses on predicting the clinical trial outcome directly based on drug molecules, target diseases, and eligibility criteria.

**A**: The methods of both Zou and Zhang, (2015) and Castoe et al., (2009) require that the foreground lineages share the same amino acid. However, there are cases where replicated changes in protein function arise from different amino acids at the same site (Zhen et al., , 2012; Mohammadi et al., , 2022). One approach to address this is to relax the requirement for each foreground lineage to have evolved the same amino acid. For example, this can be achieved running the above two methods multiple times for different subsets of the foreground lineages**B**: However this approach is computationally intensive for studies with a large number of foreground lineages (Fukushima and Pollock, , 2023). Chabrol et al., (2018) developed a model that inherently accommodates situations where some foreground species have different amino acids. Their approach steps away from explicit ancestral sequence reconstruction and instead uses a Continuous Time Markov Model of sequence evolution to determine the likelihood of replicated amino acid transitions occurring in the phylogeny branches leading to the foreground lineages. The ConDor workflow (Morel et al., (2024), available as a web-based tool) can also facilitate some foreground lineages not sharing a particular amino acid by allowing the user to specify a minimum number of lineages required to share the same amino acid substitution**C**: Their approach was designed to account for potential uncertainty in phenotypic classification, which can be common in viral studies. The Profile Change with One Change (PCOC) method (Rey et al., , 2018) takes a different approach to modeling variation in the amino acids of the foreground lineages by identifying sites where the foreground lineages have a different amino acid preference (e.g. a preference for a hydrophobic versus hydrophilic amino-acid) compared to the background lineages. While the other approaches focus solely on the most common amino acid in the foreground lineages, PCOC uses all the amino acids in the foreground lineage to determine changes in amino acid profile. Additionally, both the “PC” and “OC” components of the model can be used independently, allowing for analysis of a range of amino acid replication scenarios.

**A**: While it is true that between minutes 5 and 6 more than one ant reaches the barrier, the process would then be mediated by multiple ants seeking information, retaining it, and triggering a cascade**B**: From the moment this effective ant reaches the barrier, it remains activated and triggers a panic avalanche among its nestmates.
**C**: This, along with the finite nature of information retention, leads us to conclude that a more simplified mechanism explaining the shift in the CM can be understood as a single “effective ant” representing several informed ants

As autoinducers are produced by both sub-populations at a rate r𝑟ritalic_r (see [38]), and the bacteria can either switch or remain in their category, we assume that:
**B**: When a bacterium responds to an external stimulus by increasing the amount of a cellular component, the process is up-regulated, and it is down-regulated otherwise. To put it another way, the dynamics of the bacteria are regulated by both, autoinducers as well as growth of the bacteria population itself**C**: In order to capture the key qualitative ingredients of QS mechanisms in bacteria, we follow a simplified approach. In so doing, we assume that the autoinducers bind to receptors that enhance the expression of a particular gene, and its production also directly depends on the bacteria population (e. g. [25])
