Canopy structural modeling using object-oriented image classification and laser scanning [PDF]

open access: yes, 2008
A terrestrial laser scanning (TLS) experiment was carried out in the EAGLE 2006 campaign to characterize and model the canopy structure of the Speulderbos forest. Semi-variogram analysis was used to describe spatial variability of the surface.

Sequential Regulation of Neurovascular Bone Regeneration in Large Bone Defects Using Black Phosphorus‐Europium Nanosheet Integrated TPMS Biomimetic Scaffold with Photo‐Controlled Ion Release

open access: yesAdvanced Science, EarlyView.
TPBE scaffolds, in conjunction with mild photothermal effects, effectively activate the PI3K/Akt signaling cascade, thereby promoting early neuronal differentiation and neurite growth. Short‐term (12 W) in vivo implantation studies revealed no significant pathological damage to major organs, providing preliminary evidence of the material's excellent ...

Fast Terahertz Computed-Tomography Imaging With a Quantum-Cascade Laser and a Scanning Mirror [PDF]

open access: yes, 2013
A terahertz transmission imaging system based on a quantum-cascade laser (QCL), a fast scanning mirror, and a sensitive Ge:Ga detector is demonstrated. In order to reduce artifacts, special care was taken on the optics and the conversion of the measured

Magneto‐Sono‐Enhanced Nanozyme Catalysis Drives ROS‐Mediated Pathogen Killing and Mitophagy‐Linked Inflammation Control in Bacterial Pneumonia

open access: yesAdvanced Science, EarlyView.
Nebulized BN@NF nanozymes integrate boron nanosheets with Nd‐doped iron phosphide to form a sono‐magneto‐responsive Z‐scheme heterostructure. Under ultrasound and magnetic activation, BN@NF amplifies ROS generation, eradicates bacteria, disrupts biofilms, and reshapes pulmonary inflammation through NF‐κB suppression, mitophagy promotion, and M1‐to‐M2 ...

Simultaneous Electronic and Crystallographic Modulation of Cs3Bi2Br9 by Single‐Element Sn Substitution for Enhanced CO2 Photoreduction

open access: yesAdvanced Energy Materials, EarlyView.
Aliovalent B‐site substitution with Sn2+ in lead‐free perovskite, Cs3Bi2Br9, is employed to simultaneously induce lattice contraction and bromine vacancy through charge imbalance and ionic radius mismatch. The resulting structural distortion modulates the electronic structure and improves charge separation, leading to enhanced visible‐light‐driven CO2 ...

The diagnostic value of the circadian rhythm gene KLF10 in anxiety‐depressive disorders and its neuroimmune regulatory mechanisms

open access: yesAnimal Models and Experimental Medicine, EarlyView.
This graphical abstract illustrates the protective role and molecular mechanism of the circadian rhythm‐related gene KLF10, identified as a diagnostic biomarker and therapeutic target in anxiety‐depressive disorder. Model establishment and phenotypes: An anxiety‐depression model was successfully established by chronic restraint stress combined with ...

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

open access: yesBMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Optical coherence tomography and scanning laser ophthalmoscopy: Approaches to dual-channel retinal tissue imaging [PDF]

open access: yes, 2014
We report a Talbot bands-based optical coherence tomography (OCT) system capable of producing longitudinal B-scan OCT images and en-face scanning laser ophthalmoscopy (SLO) images of the human retina in-vivo, with various degrees of ...
