  摘要：Warmer temperatures and higher sea level than today characterized the Last Interglacial interval [Pleistocene, 128 to 116 thousand years ago (ka)]. This period is a remarkable deep-time analog for temperature and sea-level conditions as projected for 2100 AD, yet there has been no evidence of fossil assemblages in the equatorial Atlantic. Here, we report foraminifer, metazoan (mollusks, bony fish, bryozoans, decapods, and sharks among others), and plant communities of coastal tropical marine a...
• Autophagy maintains endosperm quality during seed storage to preserve germination ability in Arabidopsis AI翻译

  摘要：To preserve germination ability, plant seeds must be protected from environmental stresses during the storage period. Here, we demonstrate that autophagy, an intracellular degradation system, maintains seed germination ability in Arabidopsis thaliana. The germination ability of long - term (>5 years) stored dry seeds of autophagy- defective (atg) mutant and wild - type (WT) plants was compared. Long - term stored (old) seeds of atg mutants showed lower germination ability than WT seeds, althou...
• Distilling dynamical knowledge from stochastic reaction networks AI翻译

  摘要：Stochastic reaction networks are widely used in the modeling of stochastic systems across diverse domains such as biology, chemistry, physics, and ecology. However, the comprehension of the dynamic behaviors inherent in stochastic reaction networks is a formidable undertaking, primarily due to the exponential growth in the number of possible states or trajectories as the state space dimension increases. In this study, we introduce a knowledge distillation method based on reinforcement learning...
• Key language markers of depression on social media depend on race AI翻译

  摘要：Depression has robust natural language correlates and can increasingly be measured in language using predictive models. However, despite evidence that language use varies as a function of individual demographic features (e.g., age, gender), previous work has not systematically examined whether and how depression's association with language varies by race. We examine how race moderates the relationship between language features (i.e., first -person pronouns and negative emotions) from social me...
• Identifying outbreaks in sewer networks: An adaptive sampling scheme under network's uncertainty AI翻译

  摘要：Motivated by the implementation of a SARS-Cov-2 sewer surveillance system in Chile during the COVID-19 pandemic, we propose a set of mathematical and algorithmic tools that aim to identify the location of an outbreak under uncertainty in the network structure. Given an upper bound on the number of samples we can take on any given day, our framework allows us to detect an unknown infected node by adaptively sampling different network nodes on different days. Crucially, despite the uncertainty o...
• Multiple forces facilitate the aquatic acrobatics of grasshopper and bioinspired robot AI翻译

  摘要：Aquatic locomotion is challenging for land-dwelling creatures because of the high degree of fluidity with which the water yields to loads. We surprisingly found that the Chinese rice grasshopper Oxya chinensis, known for its terrestrial acrobatics, could swiftly launch itself off the water's surface in around 25 ms and seamlessly transition into flight. Biological observations showed that jumping grasshoppers use their front and middle legs to tilt up bodies first and then lift off by propelli...
• Climate change is poised to alter mountain stream ecosystem processes via organismal phenological shifts AI翻译

  摘要：Climate change is affecting the phenology of organisms and ecosystem processes across a wide range of environments. However, the links between organismal and ecosystem process change in complex communities remain uncertain. In snow- dominated watersheds, snowmelt in the spring and early summer, followed by a long low- flow period, characterizes the natural flow regime of streams and rivers. Here, we examined how earlier snowmelt will alter the phenology of mountain stream organisms and ecosyst...
• Brain mechanism of foraging: Reward-dependent synaptic plasticity versus neural integration of values AI翻译
  作者：Pereira-Obilinovic, Ulises; Hou, Han; Svoboda, Karel; Wang, Xiao-Jing
  作者单位：New York University
  摘要：During foraging behavior, action values are persistently encoded in neural activity and updated depending on the history of choice outcomes. What is the neural mechanism for action value maintenance and updating? Here, we explore two contrasting network models: synaptic learning of action value versus neural integration. We show that both models can reproduce extant experimental data, but they yield distinct predictions about the underlying biological neural circuits. In particular, the neural...

• AI can help people feel heard, but an AI label diminishes this impact AI翻译

  摘要：People want to feel heard to perceive that they are understood, validated, and valued. Can AI serve the deeply human function of making others feel heard? Our research addresses two fundamental issues: Can AI generate responses that make human recipients feel heard, and how do human recipients react when they believe the response comes from AI? We conducted an experiment and a follow - up study to disentangle the effects of actual source of a message and the presumed source. We found that AI- ...
