Self-assembled nanoparticle superlattices (NPSLs) are an emergent class of self-architected nanocomposite materials that possess promising properties arising from precise ordering. Their multiple coupled make them desirable as functional components in devices where mechanical robustness is critical. However, questions remain about NPSL and how shaping affects their response. Here, we perform situ nanomechanical experiments evidence up to 11-fold increase stiffness (∼1.49 16.9 GPa) a 5-fold...

The cytoskeleton (CSK) plays an important role in many cell functions. Given the similarities between mechanical behavior of tensegrity structures and CSK, studies have proposed different tensegrity-based models for simulating mechanics. However, low symmetry most units has hindered analysis realistic 3D structures. As a result, modeling mechanics been mainly focused on single cells or monolayers. In this paper, we propose model based finite element method We show that not only captures...

Effective sentence embeddings that capture semantic nuances and generalize well across diverse contexts are crucial for natural language processing tasks. We address this challenge by applying SimCSE (Simple Contrastive Learning of Sentence Embeddings) using contrastive learning to fine-tune the minBERT model sentiment analysis, textual similarity (STS), paraphrase detection. Our contributions include experimenting with three different dropout techniques, namely standard dropout, curriculum...

Abstract Enveloped RNA viruses are a group of with an outer membrane derived from host cell and genome consisting ribonucleic acid (RNA). These rely on machinery organelles to replicate assemble new virus particles. However, the interaction between may be disrupted by nanomaterials, such as gold nanoparticles (AuNPs) unique physical chemical properties. In this study, we investigated effects AuNPs different surface charge properties subcellular structure function mammalian cells, their two...

Abstract Milk‐derived extracellular vesicles (M‐EVs) are low‐cost, can be prepared in large quantities, and cross the gastrointestinal barrier for oral administration. However, composition of milk is complex, M‐EVs obtained by different extraction methods may affect their delivery. Based on this, a new method extracting based cryogenic freezing treatment (Cryo‐M‐EVs) proposed compared with previously reported acetic acid (Acid‐M‐EVs) conventional ultracentrifugation (Ulltr‐M‐EVs). The...

Metal surface quality control is significant in the production line of metal products. Detecting defects challenging due to various types and morphological patterns. Recent advances have witnessed deep learning-based automated optical inspection systems as a promising solution. This paper presents an enhanced YOLOv4 model for defect detection (MSDD). Specifically, we integrate three boosting components into original YOLOv4, including 1) self-dependent attentive fusion (SAF) block, placed...

This paper describes the shaking table tests carried out at European Centre for Training and Research in Earthquake Engineering (EUCENTRE) to investigate seismic behaviour of four configurations stacked concrete blocks, commonly used Organisation Nuclear (CERN) as a shielding barrier against different types radiation. The blocks these have been designed guarantee an adequate level protection radiation and, same time, be easily transported managed installations. block configuration specimens...

Abstract Hierarchical heterostructures of two-dimensional (2D) nanomaterials are versatile platforms for nanoscale optoelectronics. Further coupling these 2D materials with plasmonic nanostructures, especially in non-close-packed morphologies, imparts new metastructural properties such as increased photosensitivity well spectral selectivity and range. However, the integration nanoparticles has largely been limited to lithographic patterning and/or undefined deposition metallic structures....

Topologically interlocking material (TIM) systems offer adjustable bending stiffness controlled by external pre-stress. This study focuses on a specific TIM system comprised of truncated tetrahedral particles interconnected via tensioned wires. The fabrication process involves weaving nylon wires through 3D printed tetrahedrons that have longitudinal and latitudinal through-holes. By varying the tension applied to wires, one can systematically control overall system. We change surface...

Phenylketonuria(PKU) is a kind of genetic and metabolic disease which caused by mutations. High concent phenylalanine its metabolites in the blood result impairment brain development, even mental retardation. In recent years, due to impact factors diet environment, PKU was significantly increased. Studies have shown that early detection abnormal levels treatment will greatly reduce rate Therefore, monitoring particularly important for phenylketonuria patients. This study discussed new method...

Abstract This paper proposes a simpler and operable method to replace the traditional detection detect mercury ion in water samples quickly easily.
