Recognizing Mechanical Behaviors of Silt-Based Foamed Concretes from Image of Pores Using Deep-Learning Strategy

Abstract The pore structure of foamed concrete exhibits an inherent interaction with mechanical behavior. This study developed a novel deep-learning (DL) strategy to predict mechanical behavior of foamed concrete based on the image of pore distribution. This framework includes tw...

Machine Learning‐Guided Additive Manufacturing of Multilayer Aerogels for Ultrabroadband, Ultralow‐Reflection Electromagnetic Shielding

The development of broadband, low-reflection electromagnetic interference (EMI) shielding materials is critically needed to suppress secondary electromagnetic pollution. Here, we report a machine learning (ML)-guided additive manufacturing strategy for precisely fabricating multi...

Diverse life histories and childhood socialization during the middle and late Dawenkou period: incremental dentin isotope evidence from the Jiaojia site, China

Investigating childhood socialization can enhance our comprehensions of families and the overall society in the past. Previous studies paid little attention to subadults, and the evidence on the intergenerational inheritance of wealth and status is still lacking. Stable isotope a...

Fluorite‐Type Silsesquioxane‐Protected Cerium Cluster as Molecular Analog of Highly Reduced Nanoceria Fragment for Efficient Photocatalysis

ABSTRACT The surface oxygen vacancy defects generated from the abstraction of lattice oxygen atoms of bulk ceria accompanied by the reduction of Ce IV to Ce III , are considered to play a pivotal role in photocatalysis. As ideal molecular models of nanoceria, atom‐precise cerium‐...

AmTH Plays an Indispensable Role in Larval Development as Well as Adult Immunity in Apis mellifera

In insects, tyrosine hydroxylase (TH) plays crucial roles in a wide variety of biological processes. However, its function in Apis mellifera remains unknown. Here, AmTH (A. mellifera TH) was cloned and characterized. Expression profiles at different stages showed that AmTH was hi...

The efficacy, immunogenicity and safety of the LZ901 vaccine for herpes zoster virus in adults 40 years of age or older: a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial

In previously completed Phase 1 and 2 clinical trials, a recombinant gE-Fc fusion protein subunit vaccine adjuvanted with aluminum hydroxide (called LZ901) demonstrated favorable safety profiles and elicited robust immune responses. This randomized, placebo-controlled, double-bli...

<title>Abstract</title> The activities in deep underground engineering may induce variations in the stress state of the rock, increasing the risk of engineering disasters. The decrease in normal stress <italic>σ</italic>_n and the increase in shear stress <italic>τ</ita...

Dual-targeted bioengineered bacterial extracellular vesicles ameliorate senile osteoporosis via SAE1-mediated NAT10 SUMOylation and ac4C-dependent glycolysis

Senile osteoporosis (SOP) is an age-related skeletal disease characterized by progressive bone loss and the deterioration of bone microarchitecture. Promoting the osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) is a potential strategy for SOP intervention...

Oceanic Thermal and Storm Dynamic Controls on Precipitation Variability of Landfalling Typhoons in Zhejiang Province, China (2000–2025)

Landfalling typhoons frequently cause severe flooding and socioeconomic losses along the eastern coast of China, yet the relative influence of oceanic and storm-related factors on precipitation variability remains insufficiently understood. This study investigates the relationshi...

Crop Growth Models: Development, Applications, Recent Advances, and Future Perspectives

Global climate change has posed a serious threat to agricultural production and food security. Crop growth models, with their excellent simulation and prediction capabilities, have become one of the important tools for guiding agricultural production and ensuring food security. T...

Biophysical reprogramming of immunosuppressive neutrophils by cold atmospheric plasma reinvigorates antitumor immunity

Neutrophils are increasingly recognized as key orchestrators of the immunosuppressive tumor microenvironment, yet their intrinsic plasticity, short lifespan and resistance to genetic manipulation have impeded therapeutic targeting. Here, we report a non-pharmacological, biophysic...

Antarctic Circumpolar Current creates a boundary limiting the meridional dispersal of bacteria in the Southern Ocean

Impact statement As the world's largest ocean current in terms of volume transport, the Antarctic Circumpolar Current (ACC) significantly affects the movement of heat and water in the Southern Ocean. However, the impact of the ACC on the biogeographic distribution of marine bacte...

A transposon-derived transcription factor senses ionic stress through phase separation to govern plant autophagy

Salt stress severely impairs plant growth through two distinct cellular insults: osmotic stress caused by water limitation and ionic toxicity resulting from excessive Na + accumulation. Although plant osmosensors have been identified, the mechanisms underlying ionic stress percep...
