This paper improves the breadth-¯rst search strategy in directed automated random testing (DART) to generate a fewer number of test data while gaining higher branch coverage, namely Static DART or SDART for short. In addition, the paper extends the test data compilation mechanism in DART, which currently only supports the projects written in C, to generate test data for C++ projects.

This study outlines a nanotechnology-based method to enhance its solubility and absorption of rosuvastatin. The process entails the formulation of rosuvastatin nanoparticles through a combination of precipitation and ultrasonic techniques. Rosuvastatin is initially dissolved in an organic solvent, such as acetone, and subsequently mixed with an aqueous phase containing stabilizers like Poloxamer 407 or PVP to induce precipitation. Ultrasound reduces particle size to 50-200 nm.

Red phosphorus is an important ingredient in the manufacture of pyrotechnic smoke and is likely to be in service for many years. One of the most effective ways to use smoke screens is to protect special vehicles from laser and infrared guidance systems. In this work, the formulation, obscurant and emission characteristics of the smoke composition in smoke devices used in special vehicles were determined and evaluated.

Resveratrol is a naturally occurring compound with anti-inflammatory properties. However, the protective molecular mechanisms of resveratrol against LPS-induced inflammation have not been thoroughly known. In the present study, we examined the antiinflammatory effect of resveratrol in inflammatory model using murine macrophage-like cell RAW264.7 stimulated with LPS. Resveratrol suppressed the production of inflammatory cytokines in LPS-stimulated RAW264.7 cells with the IC50 value as 17.5 ± 0.7 μM for IL-6, 14.2 ± 1.9 μM for IL-10, and 18.9 ± 0.6 μM for TNF-α.

In this study, a computational investigation of the physicochemical properties of hypericin and pseudohypericin revealed drug-like characteristics. Pharmacokinetic predictions indicated that hypericin and pseudohypericin are non-toxic to the central nervous system, hepatic system, and cardiac system. Molecular docking results indicated a strong binding affinity of hypericin/pseudohypericin with MPXV thymidylate kinase. As a result, these compounds are being considered as potential Mpox control candidates.

This paper investigates the problem of finite-time stability for discrete-time neural networks with sector-bounded neuron activation functions and interval-like timevarying delay. The extended reciprocally convex approach is used to establish a delay-dependent sufficient condition to ensure finite-time stability for this class of systems.

Salicylic acid (SA), sodium benzoate (SB), phenoxyethanol (PO), and benzyl alcohol (BA) are “non paraben” preservatives commonly used in cosmetic products like shampoos, and often in combination of at least two compounds to assure their antimicrobial effectiveness at low concentrations. In this study, an HPLC-DAD method was developed and validated for simultaneous determination of SA, SB, PO, and BA in commercial shampoos.
