**A**: Given RhoFold+’s high accuracy and speed, we finally conducted ablation studies to understand which components and information are important to RhoFold+’s predictions. The architectural components we investigated included 4 different modules (Fig.5a, see Methods)**B**: Ablation studies were performed on 138 PDB targets (collected between April 2022 and December 2023) with sequence similarities below 80% to our training set and lengths ranging from 16 to 300 nt (the ‘Ablation set’). By removing each RhoFold+ component, we observed that all contributed to improving the performance, with the MSA module being the most critical, followed by the RNA-FM language model (Fig.5a)**C**: The RNA-modified version of AlphaFold2, without the MSA module, performed worse than RhoFold+ (Fig.5a). Notably, removing RNA-FM led to a sharper performance decline for dissimilar sequences (Fig.5b), and the RNA-FM module seemed to compensate for the loss of the MSA module, maintaining higher TM-scores (Fig.5c). Additionally, removing the recycling module most significantly affected predictions for longer sequences, likely due to its role in effectively deepening the model (Supplementary Figure 7; detailed discussion in Supplementary).

**A**: In Tsamardinos et al. six AutoML tools were compared [14]. Of these, only one had a predictive performance estimation strategy that could adjusts for multiple model validations (limitedly to SO problems and not affecting model selection), while most of the tools have the necessity to withold a test set for an unbiased estimation of the performance of the winning model, thus loosing samples from the final model training.**B**: Although various methods have been developed to enhance performance estimation in model selection using k-fold CV, their design and implementation have been limited to SO problems. Tsamardinos et al. [12] compared double CV, the Tibshirani and Tibshirani method [13], and nested CV in their ability to improve the estimation of the fitness for SO problems**C**: These algorithms modify fitness estimations but do not change the model selection process; the chosen model remains the same as it would be using simple hyperparameter optimization with k-fold CV for model evaluation. Automated ML (AutoML) tools offer an approach designed to explore various model and hyperparameter combinations. These tools aim to identify and deliver the most effective model along with an assessment of its performance

**A**: The tasks above concern prediction of static properties, including structures**B**: Because molecular dynamics trajectories consist of sequences of structures, GNNs should be useful for identifying features for computing reaction statistics, and several groups have combined GNNs with VAMP [8] to learn metastable states and relaxation time scales of both materials and biomolecules [31, 32, 33, 34, 35]**C**: These groups report improved variational scores, convergence for shorter lag times, and more interpretable learned representations relative to VAMPnets based on fully connected networks. However, existing GNNs for analyzing dynamics do not readily scale to large numbers of atoms, so the graphs in these studies are small, either because the molecules are small, or only a subset of atoms (e.g., the Cα atoms of proteins) are used as inputs.

Considering this structure leads to more realistic models of the epidemic. **B**: This trend also intensified during the Covid-19 pandemic, where network based epidemic models were applied and developed, in an attempt to prevent the spread of the disease [17, 18]. While classical deterministic models assume a homogeneously-mixed population, in practice populations are not fully-mixed and more likely to behave as a complex network [19]**C**: Namely, in a real population diseases spread between individuals only when they are actually in contact with one-another.

**A**: In summary, we have shown that fast antigenic drift can induce selection for complex adaptive immune responses, in line with our general picture of complexity in dynamical recognition systems**B**: These processes depend on the long-term co-evolution of host immune systems and multiple viral pathogens [86], which is beyond the scope of this paper. Other features of immune recognition not contained in the minimal model include a feedback of recognition onto the speed of target evolution. If epitope mutations come with a collateral cost to the pathogen (for example, through their effect on protein stability), a complex immune response can slow down or halt antigenic drift; this effect has recently been reported for measles [76].**C**: This finding is consistent with observations: several fast-evolving RNA viruses, including influenza [25, 82], norovirus [69], and Sars-Cov-2 [83, 84, 85], are subject to multi-epitope responses, although successful targeting of a single epitope is sufficient for neutralization [75].

In the realm of disease incidence, the seminal work by Bettencourt et al. reported that HIV/AIDS cases in the USA scale superlinearly with population size [9], a pattern also observed in Brazil by Antonio et al. [12]**B**: The authors suggest that the superlinear scaling observed in some infectious diseases likely reflects the increased number of contacts among residents in larger cities compared to smaller towns [14]. In contrast, the isometric and sublinear scaling of other infectious diseases may be due to the insufficient allocation of medical resources in smaller cities. Patterson-Lomba et al. [15] reported that sexually transmitted diseases scale superlinearly with the population of urban areas in the USA, even when controlling for socioeconomic variables. They also found that income inequality positively correlates with disease incidence, while educational level is negatively correlated.**C**: Rocha et al. [13] extended this analysis by investigating the scaling of various health indicators using data from Brazil, Sweden, and the USA. Their findings revealed that infectious diseases such as HIV/AIDS, chlamydia, and influenza generally scale superlinearly with population size.

This nonlinearity[5] poses significant challenges for traditional age prediction models, which often assume a uniform rate of change across the lifespan**B**: However, modeling DNA methylation age prediction effectively is complex due to two intrinsic properties of CpG methylation. Firstly, the correlation between CpG site methylation levels and age is not static but changes with age, which we call Epigenetic Correlation Drift (ECD)**C**: Consequently, relying on a static overall linear correlation value can overlook CpG sites that are highly correlated with age in specific ranges, such as 40-50 years, but exhibit low correlation outside these ranges. Different CpG sites exhibit distinct methylation change patterns, called Heterogeneity Among CpGs (HAC). For example, a CpG site might have a high correlation with age during one age stage but a low correlation in the next, while other CpG sites maintain a high correlation in the subsequent stage.

Phages are much smaller than bacteria and each host cell presents multiple receptors that phages can bind to, so multiple phages can adsorb to a single host cell, though not all adsorptions necessarily lead to infection**B**: Multiple adsorptions become increasingly likely at higher phage densities (Turner and Duffy, 2008; Christen et al., 1990) and can become the dominant transmission mode at sufficiently high densities (Turner and Chao, 1999). If phage densities are very high, it is possible that multiple phages simultaneously adsorb to and then infect the same host cell**C**: Here, we explore the impact of simultaneous infections on phage-host ecology. We define simultaneous infection as infections that occur within a very small time window and distinguish between simultaneous infection and previously studied forms of co-infection, where after a pause an already infected host cell is infected again. Interestingly, given sufficient time phages can prevent multiple, sequential infections through host cell manipulations (Joseph et al., 2009) but these mechanisms are not applicable to the small time window relevant for simultaneous infections.

The Text model exhibits a similar pattern with pronounced negative correlations in the frontal regions, indicating alpha rhythms are engaged during both auditory and text-encoded auditory processing, with significant involvement of cognitive control regions.**C**: The Theta band (4-8 Hz) reveals significant negative correlations in the frontal regions for both models, particularly in the prefrontal cortex, involved in working memory and executive functions during auditory processing

**A**: Even when the initial position of the agent is uniformly distributed throughout the system, the agent is not able to learn about its complete environment and gets trapped in nearest attractant peak, for low exploration rate and high learning rate**B**: When the attractant profile has peaks of different sizes, the exploration-exploitation trade off is even more pronounced**C**: As a result, even after a long time has passed, the agent may show same affinity for the lower and higher attractant peaks, which is detrimental for its performance. An optimum balance between exploitation and exploration helps the agent overcome the trapping effect and show its best performance. For non-uniform initial condition, when the agent starts near the lower attractant peak, its probability to localize near the higher peak after a long time, shows a maximum for intermediate rates of exploration and learning.

**A**: We plotted the correlation values for all the best performing models from conv1, conv2 and conv3 layers. Each point represents a signal-wise model, and the color represents the model type (blue is AFRT, red is Linear-AlexNet)**B**: Our analysis shows that the predicted activity from the AFRT model correlate higher with ground truth signals compared to the predicted activity from the baseline model Linear-AlexNet (Fig. 2)**C**: Although the baseline model makes use of a significant higher amount of features, our results show that models containing the affine components perform better (with a correlation value of 0.5 or higher). Overall, AFRT encodes MUA activity more accurately than the Linear-AlexNet model and our results also show that AFRT is less prone to overfitting.

**A**: Genes that have been previously shown to be downregulated in HD from which we obtain a negative correlation between SHAP and gene expression in SPN clusters are: Pde10A [19] or Scnb4 [20]. We have validated other lower rank genes previously described in different HD models, such as Penk1 (cluster iSPN), Gria3 (clusters iSPN, dSPN) [21] or Nrg1 [22]. Although our main focus was put on SPN clusters, other neuronal clusters are worth mentioning since they show shared altered genes with SPN clusters, eg. Gria3 and Nrg1 in clusters eSPN and adult NPC, Onecut2 in eSPN Adam12, Pcp4 in eSPN Rxrg and Adult NPC, or Pde10A in eSPN, Interneuron Whrn, Cholinergic Adrenergic neurons. **B**: Further model validation was made from SHAP results based on published data obtained from in vivo HD models or patients. For this validation, we compare the correlation between SHAP values and gene expression of previously described altered genes, expecting to observe a positive correlation between higher HD expression levels with positive SHAP values and a negative correlation between reduced HD expression levels with negative SHAP values**C**: Among the top 20 informative genes, some were previously described as being upregulated in HD. For them, we observe a positive correlation between SHAP and gene expression in SPN clusters are: Onecut2 [17] or Sfmtb2 [18]

**A**: For instance, the file parsing is highly optimized and executed with asynchronous buffers**B**: All data is read in streams, so that the number of input files, and their sizes, do not significantly affect the amount of required memory. Processor-intensive steps, such as file parsing and the statistics computations, are multi-threaded with a shared thread pool to leverage modern multi-core systems, and we paid close attention to selecting appropriate data structures for efficiency.**C**: Performance in runtime and memory was one of the major design goals
