Artificial Intelligence-Guided Inverse Design of Deployable Thermo-Metamaterial Implants.

Current limitations in implant design often lead to trade-offs between minimally invasive surgery and achieving the desired post-implantation functionality. Here, we present an artificial intelligence inverse design paradigm for creating deployable implants as planar and tubular thermal mechanical metamaterials (thermo-metamaterials). These thermo-metamaterial implants exhibit tunable mechanical properties and volume change in response to temperature changes, enabling minimally invasive and personalized surgery.

Evolution of hydraulic property and crack propagation of mine roof strata during bending-splitting deformation.

To explore the mechanism of water inrush from the mine roof strata, a series of seepage-acoustic emission (SAE) experiments on red sandstone disc samples were carried out. The effects of the height to diameter ratio (H/D) and pore pressure on the mechanical, hydraulic and crack propagation properties of red sandstones were investigated. Test results show that, the peak load of rock samples declines with the decreasing H/D and increasing pore pressure.

Cuminaldehyde Potentiates Antiproteolytic Peptide Efficacy via Parallel Pathways of Enhanced Inner Membrane-Damaging Activity and Inhibition of Bacterial Energy Metabolism.

Antimicrobial peptides (AMPs) offer potential as antibiotic alternatives, but high cost, off-site cytotoxicity, and poor stability limit their application. Combining AMPs with adjuvants holds promise in surmounting these limitations. Among potentiators, terpenoids account for the highest proportion, yet their potential to enhance the AMPs efficacy and underlying mechanism remain unclear.

Clarifying the Active Structure and Reaction Mechanism of Atomically Dispersed Metal and Nonmetal Sites with Enhanced Activity for Oxygen Reduction Reaction.

Atomically dispersed transition metal (ADTM) catalysts are widely implemented in energy conversion reactions, while the similar properties of TMs make it difficult to continuously improve the activity of ADTMs via tuning the composition of metals. Introducing nonmetal sites into ADTMs may help to effectively modulate the electronic structure of metals and significantly improve the activity. However, it is difficult to achieve the co-existence of ADTMs with nonmetal atoms and clarify their synergistic effect on the catalytic mechanism.

Beclin 1 is a core component of the phosphatidylinositol 3-kinase (PI3K) autophagy complex and positively regulates plant immunity against viruses. The upregulation of Eureka lemon ClBeclin1 was observed in response to citrus yellow vein clearing virus (CYVCV) infection.

Origin of fast charging in solid-state batteries revealed by Cryo-transmission X-ray microscopy.

The interface issue poses a limitation on the fast charging of solid-state batteries (SSBs), with the high-impedance non-Faraday electric field serving as a pivotal factor. However, the mechanism of fast-charging capability degradation triggered by the dynamic evolution of non-Faraday electric fields remains unclear due to the lack of particle-scale nondestructive detection techniques. Here, we dissect the generation and elimination processes of non-Faradaic electric field in segments using the developed operando cryogenic transmission X-ray microscopy (Cryo-TXM).

Associations of light-adapted electroretinogram in paediatric amblyopia.

Purpose: The aim of this study was to investigate changes in the light-adapted (LA) electroretinogram (ERG) associated with paediatric amblyopia.

Method: A total of 220 eyes from 81 postoperative paediatric cataract patients and 29 healthy children were enrolled in four groups, namely controls, unilaterally amblyopic eyes, non-amblyopic fellow eyes and bilaterally affected eyes. Differences in LA ERG variables (peak time and amplitude of a- and b-waves and photopic negative response [PhNR]) were compared across groups, as well as their associations with visual acuity and changes in axial length.

De novo design of Na-activated lipopeptides with selective antifungal activity: A promising strategy for antifungal drug discovery.

In recent years, invasive fungal infections have posed a significant threat to human health, particularly due to the limited availability of effective antifungal medications. This study responds to the urgent need for powerful and selective antifungal agents by designing and synthesizing a series of lipopeptides with lipoylation at the N-terminus of the antimicrobial peptide I6. Compared to the parent peptide I6, lipopeptides exhibited selective antifungal efficacy in the presence of Na.

Cerium Dioxide-Induced Abundant Cu/Cu Sites for Electrocatalytic Reduction of Carbon Dioxide to C Products.

In recent years, the electrochemical reduction of carbon dioxide (CORR) has made many advances in C production. Cu/Cu site is beneficial for C-C coupling process, but the oxidation state of copper cannot be well maintained during the reaction process, resulting in a decrease in catalyst activity. Based on this consideration, in this work, transition metal oxide CeO with a hollow cube structure and oxygen vacancies was introduced to stabilize and increase Cu/Cu active sites (CeCu).

Optimized designs for micropillar cavity with simultaneously high quality factor and Gaussian far field at near-wavelength diameter.

Micropillar cavities with small volumes and high quality factors (Q-factor) greatly enhance the light-matter interaction. Crucially, these cavities exhibit a near-Gaussian far-field pattern, making them highly suitable for efficiently coupling and manipulation of emitted photons. However, their miniaturization into near-wavelength scales is limited by diffraction, resulting in both Q-factor degradation and far-field emission divergence.

However, current segmentation methods often use addition or concatenation to fuse PET and CT images, which potentially overlooks the nuanced interplay between these modalities.

Biomechanics Model to Characterize Atomic Force Microscopy-Based Virus-Host Cell Adhesion Measurements.

We present a model for virus-cell adhesion that can be used for quantitative extraction of adhesive properties from atomic force microscopy (AFM)-based force spectroscopy measurements. We extend a previously reported continuum model of viral cell interactions based on a single parameter representing adhesive energy density by using a cohesive zone model in which adhesion is represented by two parameters, a pull-off stress and associated characteristic displacement. This approach accounts for the deformability of the adhesive receptors, such as the Spike protein and transmembrane immunoglobulin and mucin domain (TIM) family that mediate adhesion of SARS-CoV-2 and Ebola viruses, and the omnipresent glycocalyx.
