Prmt5 is essential for intestinal stem cell maintenance and homeostasis
Published 2025-02-01“…Mechanistically, Prmt5 sustains a high level of H3K27ac accumulation by inhibiting Hdac9 expression in the intestinal epithelium, and maintains the stemness of ISCs in a cell-autonomous manner. Notably, inhibition of histone deacetylases can rescue both self‐renewal and differentiation capacities of Prmt5‐depleted ISCs. …”

Cooperative trajectory prediction system for intelligent and automated connected convoy based on blockchain
Published 2020-06-01“…Autonomous vehicles have been extensively researched and developed rapidly in recent years.However,these vehicles may be not able to avoid collision with vehicles that appear suddenly.To solve this problem,a cooperative trajectory prediction system for intelligent and automated connected convoy based on blockchain was proposed.In the proposed system,each node in the intelligent and automated connected convoy and roadside infrastructure predict the trajectory of vehicles around them with the LSTM model,and they share the information they get.Using blockchain,the intelligent and automated connected convoy and roadside infrastructure rate the received messages.The summarized rating will be stored as a block in the blockchain that stores the trust values.Vehicles in the intelligent and automated connected convoy are able to judge whether the other nodes in the Conroy are credible according to their trust value,and messages from the low trust value sender will be ignored,thus achieving cooperative driving.Experiment shows that the proposed system plays a significant role in improving driving safety of the intelligent connected platoon.…”

Walking into the wild. A transition to a co-evolutionary landscape
Published 2023-06-01“… This research paper attempts to shift the approach and the possible attitudes of architectural and landscape design towards an interpretation of ecological transition based on the dimension of the ‘wild’, that is, on the possibility that the transformation of places by man contemplates other and the most diverse forms of life, spheres of proximity in which human activities give way to third and fourth natures, which develop their own habitats in an autonomous, dynamic and vital manner. In this reflection, thinking about a ‘landscape of the wild’ means thinking again about the relationship between human and natural habitats, which develops on many levels that cannot be reduced and simplified in the impending phenomenon of ‘rewilding’, ranging from the possibility of giving shape to the spaces of nature, of creating new forms of shared spaces between man and living things, to the conception of minimal architectures necessary to stimulate ancient human practices (such as walking) and which are capable of developing new ecologies. …”

Trajectory planning of UUV-assisted UWOC systems based on DQN
Published 2023-05-01“…As a key submarine-based communication platform, unmanned underwater vehicle (UUV) can facilitate underwater wireless optical communication (UWOC).However, fluctuating characteristics of water body, different water qualities, multi-user access present challenges to UUV-assisted UWOC systems, which could be alleviated by an appropriate path planning to maximize the system and each user performance.Deep reinforcement learning (DRL) technology was applied in the path planning of autonomous vehicles, a trajectory planning scheme for UUV-assisted UWOC systems was proposed.The UUV automatically decides the navigation direction through deep Q-network (DQN) method, thereby improving the communication capacity of the system and each user.The impact of distinct water qualities on the capacity enhancement was also investigated.Simulation results suggest that the outputted strategy of DQN can improve the link capacity of the system and each user.This capacity improvement in clear seawater is better than that in pure seawater but lower than that in coastal water.…”
