A Low‐Cost, Handheld Optical Stiffness Sensor for Minimally Invasive Surgery

open access: yesAdvanced Robotics Research, EarlyView.
A novel handheld stiffness sensor is presented for real‐time tissue stiffness characterization. By simultaneously sensing contact force and tissue deformation, the device enables accurate stiffness quantification without requiring precise manual control. This approach offers a promising solution for intraoperative tumor detection and minimally invasive

Climate Change Threatens Micronutrient Density of European Winter Wheat

open access: yesAdvanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Research on the damage evolution law of iron tailing sand based foam concrete under cyclic loading

open access: yesCase Studies in Construction Materials
In order to investigate the dynamic response of iron tailing sand based foam concrete as a roadbed filler, graded cyclic loading and unloading tests were carried out in this paper to examine its dynamic properties. The hysteresis curve, fatigue strength,

Amuc_1473 Links Gut Microbes to Skeletal Homeostasis and Counteracts Multifactorial Osteoporosis

open access: yesAdvanced Science, EarlyView.
Amuc_1473, a previously uncharacterized protein enriched in Akkermansia muciniphila‐derived extracellular vesicles, is identified as a gut–bone messenger that promotes osteogenesis and inhibits osteoclastogenesis by engaging transcriptional and translational regulators in bone cells.

Experimental study on stress of large-section loess tunnel lining structure under cyclic loading and unloading

open access: yesYantu gongcheng xuebao
Surface cracks have a high propensity to emerge in shallowly buried large-section loess tunnels. The lining structure endures repeated loading and unloading actions due to periodic infiltration of seasonal rainfall or agricultural irrigation, thereby ...

TME/NIR Dual‐Responsive Zinc‐Based Targeted Nanoagonist for Multimodal Amplification of STING‐Mediated Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A multifunctional nanoagonist (cDZ@IP) enables nano‐metabolite–driven multimodal activation of the STING pathway and enhanced immune recognition, achieving potent antitumor immunity and suppressing tumor growth and metastasis. This strategy highlights the rational design of therapeutic metabolites and establishes a new paradigm bridging nanomedicine ...

Cyclic lateral loading of monopile foundations in cohesionless soils

open access: yes, 2015
The monopile is the dominant foundation type for offshore wind turbines, with current design guidance based on knowledge transferred from the oil and gas industry. Whilst there are some similarities between wind turbine and oil and gas pile design, there
