The continuous global effort to predict material properties through artificial intelligence has predominantly focused on utilizing material stoichiometry or structures in deep learning models. This study aims to predict material properties using electrochemical impedance data, along with frequency and time parameters, that can be obtained during processing stages. The target material, silica aerogel, is widely recognized for its lightweight structure and excellent insulating properties, which are attributed to its large surface area and pore size.

Elastic relaxation of lattice misfit strain via traction-free surface results in complex 3D strain distribution and morphological modification at the boundary of epitaxial heterostructure. While this phenomenon is extensively studied, the influence of the interface coherency constraining the strain relaxation has received little attention. Here it is shown that the interfacial shear stresses arise toward the traction free sidewall of microscale light emitting diode (LED) wires while the two complementary strained InGaN and GaN layers are relaxed to revert their bulk lattice parameters near the sidewall.

Mass spectrometry-based lipidomics, developed through rapid advancements in instruments and techniques, provides comprehensive analyses of individual lipidomes in diverse biological systems. This contribution summarizes the limitations of classical methods for measuring lipid oxidation in foods and presents current novel technologies for evaluating lipid oxidation. Notably, this study introduces the mass spectrometry-based lipidomics approach and its utility in assessing lipid oxidation through various analytical modes, supported by numerous examples.

Background: This study aimed to evaluate the progress of treatment with intensive targeted therapy in high-risk pulmonary arterial hypertension (PAH) patients and focused on setting an appropriate hemodynamic target of pulmonary vascular resistance (PVR) ≤4 Wood units (WU) and mean pulmonary arterial pressure (mPAP) ≤ 40 mmHg.

Methods: We retrospectively evaluated high-risk PAH patients who were administered treprostinil at a single tertiary pulmonary hypertension center between January 2020 and December 2022. Echocardiography, right heart catheterization, 6-minute walk distance (6MWD), and blood tests were obtained 6 and 12 months after the initiation of parenteral treprostinil administration.

Branched-chain amino acids (BCAAs) are important for normal growth, development, and function. In urea cycle disorders (UCDs), plasma BCAA levels can be relatively low; this has been attributed variously to low protein intake, hyperammonaemia, and nitrogen scavenger treatment. We undertook a retrospective review of plasma BCAA levels in individuals with UCDs comprising ornithine carbamoyltransferase deficiency (OTCD  = 22), arginosuccinate lyase deficiency (ASLD  = 12), and argininosuccinate synthase deficiency (ASSD  = 6).
