Architectural metamaterials that span different length scales and are either self-similar or dissimilar to one another make up hierarchical lattices. Comparing hierarchical lattices to traditional ones reveals that they offer superior and customizable properties, which allows for a wide variety of material property manipulation and optimization. Each computer network can be represented as a graph, where nodes alternate as vertices and links are edges. The recent advanced topic of resolvability parameters of a graph involves shaping the entire structure to obtain each nodes' specific position. In this article, we computed the metric, fault metric, and partition dimension of the hierarchal lattic tube. The application of the metric dimension is also covered in this paper.

A search for antifungal compounds from the mushroom using a bioassay-guided chromatographic fractionation approach led to the discovery of a novel polyketide harboring a rare 3,3a,9,9a-tetrahydro-1-furo[3,4-]chromen-1-one skeleton. The novel compound was named coprinolide. The inhibitory activity and fungicidal potential of coprinolide were evaluated against five economically important plant-pathogenic fungi.

Here, we proposed and experimentally demonstrated a quasi-distributed high-temperature sensor based on an SFBG array sealed in an argon gas-infiltrated sapphire tube interrogated by using an InGaAs-based interrogator. An SFBG array including five SFBGs was inscribed using the femtosecond laser line-by-line method and sealed in an argon gas-infiltrated sapphire tube.

Firstly, two standard single-mode fibers are interposed into a capillary tube to constitute a cantilever beam structure FPI. FPI achieved a high axial strain sensitivity of 15.

Based on the air-backed push-pull fiber optic hydrophone structure, the inner elastic tube is replaced by a thick hollow column, introducing axial acoustic pressure sensing to improve the detection sensitivity of the fiber optic hydrophone. The influence of axial stress on the deformation of the composite structure is investigated by theoretical analysis and numerical simulation, and the structural design of fiber optic hydrophone with high acoustic pressure sensitivity and wide frequency response range is realized.
