AI Article Synopsis
- The study explores how guided waves can be used to identify defects by examining how different shapes and sizes affect transmitted and reflected wave fields.
- Using a hybrid boundary element method, researchers numerically calculated and compared reflection and transmission coefficients for specific guided wave modes with experimental data.
- The research concludes that effective defect characterization is achievable if appropriate criteria for selecting wave modes are established, and that the data can aid in creating algorithms for defect identification.
Article Abstract
The potential use of guided waves for defect characterization is studied. The influence of defect shape and size on transmitted and reflected fields is considered. Using the hybrid boundary element technique, the reflection and transmission coefficients for selected guided wave modes are numerically calculated and compared to experimental data. Selecting the aspect ratio as a shape parameter for various defects, the transmission and reflection coefficients are measured for certain guided wave modes input to the defect. The influence of defect size is then studied by monitoring the transmission and reflection coefficients for defects of various shapes and depths. The studies presented indicate that defect characterization is possible if a proper mode selection criteria can be established. The suitable features related to transmission and reflection coefficient data can also be used for algorithm development and implementation purposes of defect characterization.

Hepatosplenic T-cell lymphoma (HSTCL) is an aggressive mature T-cell lymphoma characterized by significant hepatosplenomegaly, bone marrow involvement, and minimal or no lymphadenopathy. Primarily affecting young adults, it is exceptionally rare in children and adolescents. This makes diagnosis and treatment particularly challenging for pathologists and pediatric oncologists.

Finding ways to produce dense and smooth perovskite films with negligible defects is vital for achieving high-efficiency perovskite solar cells (PSCs). Herein, we aim to enhance the quality of the perovskite films through the utilization of a multifunctional additive in the perovskite anti-solvent, a strategy referred to as anti-solvent additive engineering. Specifically, we introduce ortho-substituted-4'-(4,4″-di-tert-butyl-1,1':3',1″-terphenyl)-graphdiyne (o-TB-GDY) as an AAE additive, characterized by its sp/sp-cohybridized and highly π-conjugated structure, into the anti-solvent.

Gastrointestinal Defects and Immunodeficiency Syndrome-1 (GIDID-1), caused by abnormalities in TTC7A, is an autosomal recessive disorder characterized by multiple gastrointestinal malformations and immune deficiencies, often accompanied by inflammatory bowel disease (IBD). This condition typically results in poor treatment outcomes and is usually fatal in early infancy. This paper examined the genetic abnormalities and clinical features of GIDID by analyzing data from three children and one fetus with gastrointestinal dysfunction and immune deficiency associated with TTC7A abnormalities at our hospital, and reviewed reported cases worldwide.

The cadmium-rich intermetallic compounds RhCd ( = Ca, Sr, Y, La-Nd, Sm-Lu) were synthesized from the elements in sealed tantalum tubes. The elements were reacted in an induction furnace and the samples were post-annealed to increase phase purity and crystallinity. The RhCd phases crystallize with the cubic CeCrAl type structure, space group 3̄.

Hyperpolarized Xe MRI/MRS enables quantitative mapping of function in lung airspaces, membrane tissue, and red blood cells (RBCs) within the pulmonary capillaries. The RBC signal also exhibits cardiogenic oscillations that are reduced in pre-capillary pulmonary hypertension (PH). This effect is obscured in patients with concomitant defects in transfer from airspaces to RBCs, which increase RBC oscillation amplitudes.
