Abstract Although the taxonomic composition of human microbiome varies tremendously across individuals, its gene or functional capacity is highly conserved — implying an ecological property known as redundancy. Such redundancy has been hypothesized to underlie stability and resilience microbiome, but this hypothesis never quantitatively tested. The origin still elusive. Here, we investigate basis for in by analyzing genomic content network a bipartite graph that links microbes genes their...

An articulation point in a network is node whose removal disconnects the network. Those nodes play key roles ensuring connectivity of many real-world networks, from infrastructure networks to protein interaction and terrorist communication networks. Despite their fundamental importance, general framework studying points complex lacking. Here we develop analytical tools study issues pertinent points, e.g. expected number them vulnerability against removal, an arbitrary We find that greedy...

Recent advancements in Large Vision-Language Models (LVLMs) highlight their ability to integrate and process multi-modal information. However, hallucinations—where generated content is inconsistent with input vision instructions—remain a challenge. In this paper, we analyze LVLMs' layer-wise decoding identify that hallucinations can arise during the reasoning factual information injection process. Additionally, as number of tokens increases, forgetting original prompt may also lead...

Large language models (LLMs) like ChatGPT have exhibited remarkable abilities on a wide range of natural processing (NLP) tasks, including various machine translation accomplished during chat. However, these are only accessible through restricted APIs, which creates barriers to new research and advancements in the field. Therefore, we propose ParroT, framework enhance regulate chat based open-source LLMs (e.g., LLaMA), human-written feedback data. Specifically, ParroT reformulates data into...

Abstract The initial transient phase of an emerging epidemic is critical importance for data-driven model building, model-based prediction the trend, and articulation control/prevention strategies. Quantitative models real-world epidemics need to be memory-dependent or non-Markovian, but this presents difficulties data collection, parameter estimation, computation, analyses. In contrast, such do not arise in traditional Markovian models. To uncover conditions under which non-Markovian are...

Structural vulnerability of a network can be studied via two key notions in graph theory: articulation points (APs) and bridges, representing nodes edges whose removal will disconnect the network, respectively. Fundamental properties APs bridges classical random networks have been recently. Yet, it is unknown if those still hold quantum networks. Quantum allow for transmission information between physically separated systems. They play very important role computing, communication, sensing....

In many real-world scenarios, we decentralized protocol guide system (e.g., unmanned vehicles or nanorobots) reach an ordered state prompt noise-robust manner. Here,...
