A soft, skin-mounted microfluidic device captures microliter volumes of sweat and quantitatively measures biochemical markers by colorimetric analysis.
Prominent techniques such as real-time polymerase chain reaction (RT-PCR), enzyme-linked immunosorbent assay (ELISA), and rapid kits are currently being explored to both enhance sensitivity reduce time for diagnostic tests. Existing commercial molecular methods typically take several hours, while immunoassays can range from hours tens of minutes. Rapid diagnostics crucial in Point-of-Care Testing (POCT). We propose an approach that integrates a time-series deep learning architecture AI-based...
Abstract Background Landslide susceptibility assessment (LSA) is a crucial indicator of landslide hazards, and its accuracy improving with the development artificial intelligence (AI) technology. However, AI algorithms are inconsistent across regions strongly dependent on input variables. Additionally, LSA must include historical data, which often restricts to local scale single events. Methods In this study, we performed an for entirety South Korea. A total 30 variables were constructed,...
The methane (CH4) – carbon dioxide (CO2) swapping phenomenon in naturally occurring gas hydrates is regarded as an attractive method of CO2 sequestration and CH4 recovery. In this study, a high pressure microdifferential scanning calorimeter (HP μ-DSC) was used to monitor quantify the replacement hydrate structure. HP μ-DSC provided reliable measurements dissociation equilibrium heat for pure mixed hydrates. data obtained from endothermic thermograms replaced indicate that at least 60%...
This study aims to examine the thermodynamic feasibility of separating sulfur hexafluoride (SF(6)), which is widely used in various industrial fields and one most potent greenhouse gases, from gas mixtures using hydrate formation. The key process variables phase equilibria, pressure-composition diagram, formation kinetics, structure identification mixed hydrates, were closely investigated verify overall concept this hydrate-based SF(6) separation process. three-phase equilibria (H), liquid...
Since many lateral flow assays (LFA) are tested daily, the improvement in accuracy can greatly impact individual patient care and public health. However, current self-testing for COVID-19 detection suffers from low accuracy, mainly due to LFA sensitivity reading ambiguities. Here, we present deep learning-assisted smartphone-based (SMARTAI-LFA) diagnostics provide accurate decisions with higher sensitivity. Combining clinical data learning two-step algorithms enables a cradle-free on-site...
This article presents a new mobile platform with two-degree-of-freedom (2-DOF) transformable wheels for service robots, which can overcome steps and stairs of various sizes encountered in indoor environments. The concept the 2-DOF wheel is introduced required transformation ranges are examined. In this article, five-bar PRRRP mechanism adopted as base transformation. Also, to separate rotation from effectively, four-bar RRPP incorporated into mechanism. design variables determined not only...
Abstract This paper describes deterministic assembly processes for transforming conventional, planar devices based on flexible printed circuit board (FPCB) platforms into those with 3D architectures in a manner that is fully compatible off‐the‐shelf packaged or unpackaged component parts. The strategy involves mechanically guided geometry transformation by out‐of‐plane buckling motions follow from controlled forces imposed at precise locations across the FPCB substrate prestretched elastomer...
Abstract During the pandemic surge, including SARS‐CoV‐2 and influenza, pooling samples emerged as an efficient strategy to identify infected individuals in large groups. While enhances RT‐PCR throughput, reducing costs resources, it dilutes positive with negative ones, lowering sensitivity increasing false negatives. This study proposes a new method address trade‐off between pool sizes accuracy. integrates large‐scale sample enrichment using nano‐hybrid membrane, preventing pooling‐induced...

This study briefly overviews the current status, challenges, prospects inventorying provides a case tree inventory assessment through student participatory program South Korea. maps from 25 universities eight countries were investigated. A usually consists various...
Background/Objectives: Ovariectomized rodents experience metabolic dysfunction in whole-body and skeletal muscle. A disrupted balance between oxidative stress antioxidants might exacerbate ovariectomized rodents. Dietary antioxidants, such as vitamin E intake, before or during exercise would be beneficial by mitigating the exercise-induced increase The purpose of current study was to investigate potential effect intake combined with voluntary on muscle metabolism mice. Methods: This used...

This paper presents a novel active noise cancellation (ANC) method to reduce the engine inside cabin of car. During last three decades, many methods have been developed for control quasi-stationary narrowband sinusoidal signal. However, since interior signal is non-stationary with fast frequency variation when car accelerates rapidly, these cannot stably noise. The proposed can even if speed changed quickly. uses an adaptive filter optimal weight vector such determining demonstrated. In...
