Summary: The study demonstrates that the yeast myosin-1 Myo5 is more likely to generate power than to serve as a force-sensitive anchor in cells. This finding has implications for Myo5's role in clathrin-mediated endocytosis.

Summary: Dimension is a fundamental property of objects and space, but its ideal notions don't always apply to physical spaces and discrete systems. This study introduces a dynamics-based notion of dimension by analyzing diffusive processes, which is relevant for non-ideal physical systems and networks. It demonstrates the application of relative dimension in various fields.

Summary: Reliable traffic flow prediction is important for traffic control and public safety. This article proposes a Global-Local Temporal Convolutional Network (GL-TCN) that effectively captures long-term local dynamics through a novel local temporal convolutional mechanism and integrates global and local flow patterns to handle the impact of global flow trend on local dynamics. Experiments demonstrate the superior performance of this method over several state-of-the-art baselines.

Summary: Temporal action proposal generation is a crucial and challenging task in video understanding, with the current mainstream methods struggling to handle both local and global dependencies simultaneously. To address this, CLGNet is proposed, integrating Temporal Convolution Network and Bidirectional Long Short-Term Memory to effectively manage local and global dependencies. Extensive experiments have demonstrated the strong capability of this method in modeling actions with varying temporal durations.

Summary: Temporal modeling in videos is crucial for action recognition. In this paper, an Efficient Action Recognition network (EAR) is proposed, consisting of Persistence of Appearance (PA) and Various-timescale Aggregation (VA) modules for local-global temporal aggregation, achieving competitive results on challenging action recognition benchmarks at low FLOPs.

Summary: In this paper, a new framework for temporal knowledge graph (TKG) representation learning with local and global structure evolutions, named EvoExplore, is proposed. The local structure evolution is defined as the establishment process of relations between entities, and a hierarchical-attention-based temporal point process is proposed to capture the formation process of the graph structure. For global structure evolution, a novel soft modularity parameterized by entity representations is proposed to capture the dynamic community partition of the TKGs. Experimental results show the superiority of EvoExplore compared with baseline methods.

Summary: A new centrality method is proposed, which combines the degree centrality and the information centrality. By using a fractional parameter gamma, the changes in the node centrality rankings are explored. The fractional centralities behave similarly to the degree centrality when gamma is close to 0, and the fractional information centrality becomes a global centrality as gamma changes from 0 to 1.

Summary: This letter proposes a novel approach for satellite video super-resolution, which utilizes a two-branch alignment network and a fusion module to improve the spatial resolution of satellite videos. Experimental results demonstrate that the proposed method can achieve comparable results to current state-of-the-art methods with fewer parameters.

Summary: This study analyzed the SH3-mediated endocytic pathway in yeast using mutagenesis and live-cell fluorescence microscopy. It was found that multiple SH3 domains regulate the assembly and dissociation of the actin nucleation-promoting complex Las17-Vrp1. Most endocytic SH3 domain proteins use the domain for their own recruitment, while a minority use it to recruit other proteins. These results provide a dynamic map of SH3 functions in yeast endocytosis and a framework for studying SH3 interaction networks in biology.

Summary: In this study, we investigate the time evolution of the density of active links and the entropy of the distribution of agents among opinions in multistate voter models on uncorrelated networks with all-to-all interaction. We find that the density of active links decays exponentially, while the average entropy decays exponentially only when there are at most two opinions left in the population.

Summary: This study investigates the impact of adaptive CNVs with different structures and copy numbers on genetic mutational tolerance and genome-wide genetic interactions in Saccharomyces cerevisiae strains evolved under glutamine-limited conditions. It is found that CNVs increase mutational target size, confer increased mutational tolerance in amplified essential genes, and result in novel genetic interactions with unlinked genes. Furthermore, CNV strains show decreased fitness compared to the wild-type ancestor in rich media, and most genes amplified by CNVs are not affected by transcriptional dosage compensation.

Summary: This study analyzed the integration of the Tf1 retrotransposon in Schizosaccharomyces pombe and found a palindromic pattern in its integration sites, indicating interaction with subunits of the integrase oligomer. Furthermore, the study showed that Tf1 integration favors regions with nucleosome depletion.

Summary: This paper proposes a novel network called the Local-Global Transformer Neural Network (LGTNN) to address the limitations of using Transformer-based networks for video processing. LGTNN efficiently captures multiscale features, solves the paradox of perceiving higher- and lower-level representations, and improves performance through a refinement process. Experimental results demonstrate that LGTNN outperforms state-of-the-art methods in temporal action segmentation.

Summary: Dynamic actin filaments are essential for the formation and internalization of endocytic vesicles. Pan1p and Ent1p/2p cooperatively regulate the interaction between the endocytic vesicle and the actin cable.
