Construction of AlGaN/GaN high-electron-mobility transistor-based biosensor for ultrasensitive detection of SARS-CoV-2 spike proteins and virions

The COVID-19 pandemic has highlighted the need for rapid and sensitive detection of SARS-CoV-2. Here, we report an ultrasensitive SARS-CoV-2 immunosensor by integration of an AlGaN/GaN high-electron-mobility transistor (HEMT) and anti-SARS-CoV-2 spike protein antibody. The AlGaN/GaN HEMT immunosensor has demonstrated the capability to detect...

General Optimal Trajectory Planning: Enabling Autonomous Vehicles with the Principle of Least Action

This study presents a general optimal trajectory planning (GOTP) framework for autonomous vehicles (AVs) that can effectively avoid obstacles and guide AVs to complete driving tasks safely and efficiently. Firstly, we employ the fifth-order Bezier curve to generate and smooth the reference path along the road centerline. Cartesian coordinates...

An agent-based resilience model of oil tank farms exposed to earthquakes

Frequent unpredictable earthquake disasters such as the Turkey Earthquake in 2023 pose an increasing threat to oil tank farms since they may trigger major accidents and domino effects, resulting in casualties, economic losses, and environmental pollution. Unpredictable earthquakes are definitely difficult to prevent and thus resilience...

基于热力学模拟的碱激发材料物相演变与耐久性能研究进展

Alkali-activated materials (AAMs) are one of green cementitious materials in building materials industry and beneficial to the goals of carbon peaking and carbon neutrality. Compared with ordinary Portland cement (PC) based materials, however, the raw material composition, reaction products and pore solution composition of AAMs are complex...

Biointegration of architecture and ecology system

Many species that are dependent on buildings are beginning to appear as more and more species of nature learn to adapt to city life. In the same vein, the concurrent loss of biodiversity presents a problem for the planning of vertical greening. This article attempts to explore the combination of animal nesting and vertical greening to develop a...

Extending SymbolicPlanners with forward propagation landmark extraction

The Fast Downward planning system is currently mainly used for solving classical problems. Another alternative to Fast Downward is SymbolicPlanners, which sacrifices speed for generality and extensibility. SymbolicPlanners is missing landmark based planners and landmark extraction algorithms. The research question we are trying to answer in this...

The Hotel—Wellness Spa Segment: ImmerseFlow

ImmerseFlow is a Wellness Spa hotel segment that blends sensory treatment with water-enhanced tranquility. It is part of The Hotel, a collective project that studies the hotel, both as a building type and as a place of hospitality, through a collection of fourteen individual contributions inside one skyscraper. The project imagines hospitality...

The Hotel—Chain Segment: Marriott Metropolitan

Marriott Metropolitan is a chain hotel segment that entices business travelers to extend their journey. It is part of The Hotel, a collective project that studies the hotel, both as a building type and as a place of hospitality, through a collection of fourteen individual contributions inside one skyscraper. The project...

Directly serving 3D Tiles from a Geo-DBMS

The rise of urban digital twins emphasises the critical role of representing real-world environments for decision-making and collaboration among stakeholders. This leads to an expectation of effective management and visualisation of large-scale urban data models. 3D Tiles is an open specification designed for streaming and rendering massive...

Waste Houses: Messing up The Netherlands

The Netherlands has the ambition to transition to a fully circular economy before 2050. Between this future and where we stand now, there is still a large gap. The Netherlands produces 60 million tonnes of waste per year. This fact contains two problems that this project aims to deal with: 1) the heigh of this number in the first place, and 2)...

River Recovery: A pilot for making healthy rivers in Europe

Only 1% of the surface water in the Netherlands has been classified as ‘good’, making it the EU member state with the worst quality of surface water (Didde, 2022). Polluted rivers cause problems such as worsened human health, reduced biodiversity, and poor soil fertility. To comply with the Water Framework Directive, there is an urgent need to...
