Theory predicts that the approach of catastrophic thresholds in natural systems (e.g., ecosystems, climate) may result an increasingly slow recovery from small perturbations, a phenomenon called critical slowing down. We used replicate laboratory populations budding yeast Saccharomyces cerevisiae for direct observation down before population collapse. mapped bifurcation diagram experimentally and found became more vulnerable to disturbance closer tipping point. Fluctuations density increased...
Significance Alternative stable states and critical transitions are widespread in nature can have profound consequences for conservation, climate changes, human health. Our current toolbox of early warning signals before has seen both successes failures. Understanding the limitations these indicators is crucial application real-world scenarios. In this study, we explored population dynamics laboratory yeast under different forms environmental deterioration. We found that performance drivers...
In the waterway construction projects of upper reaches Yangtze River, crushed mudstone particles are widely used to backfill foundations rock-socketed concrete-filled steel tube (RSCFST) piles, a structure adopted in port constructions. these projects, steel–mudstone interfaces experience complex loading conditions, and surface profile tends vary within certain ranges during operation. The changes boundary conditions material significantly impact bearing performance piles when subjected...
The sudden increase in high latitude ionospheric currents and two-cell convection are both important elements during geomagnetic substorms. Although simulations statistical analyses suggest a relationship between the two phenomena magnetosphere-ionosphere coupling, spatiotemporal correlation of their evolution observation has not been clearly demonstrated. Here we select multiple continuous strong substorms under storm as case to effectively reveal synchronous field-aligned (FACs) auroral...
 Previous research has established that in geospace, the total electron content (TEC) ionosphere can be modulated efficiently by ultralow frequency (ULF) waves high-latitude regions. However, correlations between TEC variations and ULF middle-latitude low-latitude regions remain inadequately explored. In this study, using ground-based magnetometer data from Chinese Meridian Project, we identified wave events within Pc4 bands midlatitude region. During period July 1 December 30,...
Combination atlas–axis fractures are less studied but relatively common with a higher incidence of neurological deficits than isolated C1 or C2 fractures. Several authors focused on the treatment strategies, there is no study to compare stability different fixation methods; neither not yet clear which technique represents best choice and whether stabilization devices can be efficient beneficial for complex atlantoaxial The aim this was biomechanical properties three techniques: pedicle...
Following the pioneering observations with COBE in early 1990s, studies of cosmic microwave background (CMB) have focused on temperature and polarization anisotropies. CMB spectral distortions - tiny departures energy spectrum from that a perfect blackbody provide second, independent probe fundamental physics, reach deep into primordial Universe. The theoretical foundation has seen major advances recent years, which highlight immense potential this emerging field. Spectral property Universe...

Machine unlearning (MU) has gained significant attention as a means to remove specific data from trained models without requiring full retraining process. While progress been made in unimodal domains like text and image classification, multimodal remains relatively underexplored. In this work, we address the unique challenges of CLIP, prominent model that aligns visual textual representations. We introduce CLIPErase, novel approach disentangles selectively forgets both associations, ensuring...
Audio-Visual Question Answering (AVQA) is a challenging task that involves answering questions based on both auditory and visual information in videos. A significant challenge interpreting complex multi-modal scenes, which include objects sound sources, connecting them to the given question. In this paper, we introduce Source-aware Semantic Representation Network (SaSR-Net), novel model designed for AVQA. SaSR-Net utilizes source-wise learnable tokens efficiently capture align audio-visual...
In this study, different modeling approaches used in panel data for performance forecast of transportation infrastructure are firstly reviewed, and the models (PDMs) highlighted longitudinal sets. The state-space specification PDMs proposed as a framework to formulate dynamic facilities sets estimation. could simultaneously capture heterogeneity update through inspections. applied tackle cross-section data, forms achieve goal updating with new coming data. To illustrate methodology, three...
&lt;p&gt;A key link in the Sun &amp;#8211; Earth connection is solar wind coupling with terrestrial magnetosphere. Mass and energy enter geospace via dayside magnetic reconnection; reconnection tail leads to release of particle injection deep into magnetosphere, causing geomagnetic substorms. The end product these processes visual manifestation variable auroral emissions. These have been observed both from ground space, latter for relatively short continuous periods time. In situ...
A method of symmetric distortion correction is described and successfully applied to correct the mapping errors caused by CGH as well internal imaging optics. The aspheric surface 160 mm in diameter has a maximum departure 145 μm. According model established fiducial spots on surface, we show experimental results after direct measurement distortion-corrected error map respectively. that useful effective.
