Summary: Cytogenetic analyses on Leptodactylus bufonius in Argentina revealed a karyotype of 2n = 2x = 22 and FN = 44, with secondary constrictions in chromosome pair 8 and a sex-linked pericentromeric band in chromosome pair 4. The presence of heteromorphic XY sex chromosomes in L. bufonius is the second case within the genus Leptodactylus and the fifth within the family Leptodactylidae.

Summary: The study conducted a cytogenetic analysis on five out of the seven species of the genus Lyciasalamandra, revealing a high diversity in karyotype configuration and nucleolus organizing regions (NORs). The unique taxon-specific NOR configuration supports the taxonomic validity of different evolutionary lineages and suggests a scenario of synchronous evolution in the Lycian salamanders. The observed variability in NORs is likely derived from multiple independent translocations and inversions, contributing to lineage divergence in Lyciasalamandra.

Summary: The CRISPR-Cas9 system is widely used for gene editing and clinical applications. However, it can cause off-target effects. This study found significant sex differences in p53-associated Cas9 activities. Further analysis revealed sex-specific dependencies of gene knockouts in different cancer types, potentially mediated by transcriptional factors. These findings suggest the need to consider the p53-dependent sex bias in future CRISPR-Cas9 clinical applications, especially in cancer.

Summary: The study aims to generate event proposals using visual-audio cues, enhance event-level representations, capture relationships between events, and fuse multi-modal information through an attention-gating mechanism, proposing an event-centric multi-modal fusion approach for dense video captioning. Experimental results demonstrate significant progress on the ActivityNet Caption and YouCook2 datasets.

Summary: The proposed approach in this paper overcomes the limitations of current medical image fusion methods by using two algorithms to handle low-frequency and high-frequency components separately. This results in a fused image with improved contrast and preserved details, as demonstrated by experimental results.

Summary: Some organisms have brightly colored structures that are only visible when they are in motion, such as wing parts visible during flight. The Carolina grasshopper uses its hindwings to startle and confuse predators before quickly returning to camouflage.

Summary: This article introduces a novel optimization framework for 3D and ego-centric relative pose estimation in a team of robots, using Ultra WideBand (UWB) nodes for obtaining pose information without relying on fixed external infrastructure. The validity of the proposed method is demonstrated through experiments.

Summary: This study identified several satellite DNAs (satDNAs) in Trigona bees, with ThyaSat01-301 being the most abundant satDNA associated with c-heterochromatin. The presence or absence of this satDNA in different Trigona species suggests divergent evolution of c-heterochromatin between clades A and B. These findings provide insights into the origin and evolutionary patterns of c-heterochromatin in Trigona bees.

Summary: Correct folding of chromosomes is crucial for proper genome function in eukaryotic nuclei. The HCHC complex affects genome organization by increasing heterochromatic region interactions when CDP-2 is lost, and decreasing heterochromatic region compaction when CHAP is lost. Additionally, loss of CDP-2 and DIM-2 leads to extensive genome disorder due to increased heterochromatin-euchromatin contacts despite additional H3K9me3 enrichment.

Summary: Grasshoppers pose a substantial threat to North American rangelands, with potential for significant economic damages. Current grasshopper forecasting efforts in the western United States are solely based on previous year's data. This study in Wyoming found that October precipitation and past grasshopper density were among the best predictors for future grasshopper population density, and environmental factors play a significant role in forecasting efforts.

Summary: A large quantity of publicly available documents, such as patents and journal articles, can inspire designers and facilitate product innovation and collaborative design. The acquisition, sharing, and reuse of design rationale (DR) is valuable to designers as it helps them grasp design intentions and ideas, support design automation, and promote better collaborative design. However, the fragmentation of DR in documentation poses a challenge for designers. This study proposes a three-dimensional design knowledge network metamodel and a knowledge fusion method to construct a Design Knowledge Network (DKN), which shows good feasibility and application prospects.

Summary: Event cameras are becoming popular due to their advantages in high dynamics or challenging illumination conditions. To promote the application of event cameras in multi-sensor SLAM, new benchmark datasets are needed. This study presents the first complete benchmark dataset with a multi-sensor setup, including event-based cameras, regular cameras, depth sensors, and inertial measurement units.

Summary: Point cloud registration is a core task in 3D perception. Traditional methods tend to fail in aligning point clouds with low overlap. Recent deep learning-based approaches lack robustness and accuracy. Therefore, the authors propose a novel registration pipeline that focuses on object-level alignment to achieve robust and accurate alignment of point clouds.
