Dynamic information flow tracking (DIFT) has been proven an effective technique to track data usage; prevent control data attacks and non-control data attacks at runtime; and analyze program performance. Therefore, a series of DIFT techniques have been developed recently. In this paper, we summarize the current DIFT solutions and analyze the features and limitations of these solutions. Based on the analysis, we classify the existing solutions into three categories, i.e., software, hardware, software and hardware co-design. We discuss the DIFT design from the perspective of whole system and point out the limitations of current DIFT frameworks. Potential enhancements to these solutions are also presented. Furthermore, we present suggestions about the possible future direction of DIFT solutions so that DIFT can help improve security levels.

Microfluidic chips often face challenges related to the formation and accumulation of air bubbles, which can hinder their performance. This study investigated a bubble trapping mechanism integrated into microfluidic chip to address this issue. Microfluidic chip design includes a high shear stress section of fluid flow that can generate up to 2.

Background: Bee venom consists of more than 50 % melittin (MLT), which has anti-cancer, anti-inflammatory, and antimicrobial properties. Bee venom also contains toxic components such as phospholipase A2 (PLA2) and hyaluronidase (HYA), which cause allergic reactions, so the toxic components must be removed to use MLT. In previous studies, analytical methods were used to separate MLT.

Objective: The study aims to elucidate the mechanisms underlying plaque growth by analyzing the variations in hemodynamic parameters within the plaque region of patients' carotid arteries before and after the development of atherosclerotic lesions.
Methods: The study enrolls 25 patients with common carotid artery stenosis and 25 with tandem carotid artery stenosis. Based on pathological analysis, three-dimensional models of the actual blood vessels before and after the lesion are constructed for two patients within a two-year period.

Theories predicted that shear promotes desorption, but due to the presence of factors such as aggregation effects, it is difficult to observe how shear influences the adsorption and desorption of individual protein molecules. In this study, we employed high-throughput single-molecule tracking and molecular dynamics simulations to investigate how shear flow affects the adsorption kinetics of plasma proteins (including human serum albumin, immunoglobulin G, and fibrinogen) at solid-liquid interfaces. Over the studied shear rate range of 0 - 10 s, shear stress did not trigger the protein desorption.

Cities exhibit diverse urban metabolism patterns in terms of the natural environment, industrial composition, energy, and material consumption. A chronicled city-level quantification of emergy metabolic flows over time can significantly enhance the understanding of the temporal dynamics and urban metabolism patterns, which provides critical insights for the transitions to sustainability. However, there exists no city-level urban emergy metabolism dataset in China that can support detailed spatial-temporal analysis.
