pH-sensitive and biodegradable charge-transfer nanocomplex for second near-infrared photoacoustic tumor imaging
The emerging photoacoustic imaging (PAI), especially in the NIR window, offers reliable sensing for deep-penetration and high-resolution closing to clinical requirements. However, the contrast agents that are capable of ...
Development of organic semiconducting materials for deep-tissue optical imaging, phototherapy and photoactivation
Biophotonics as a highly interdisciplinary frontier often requires the assistance of optical agents to control the light pathways in cells, tissues and living organisms for specific biomedical applications. Organic ...
High-speed, low-cost, pulsed laser diode based second generation desktop photoacoustic tomography system
Bulky, expensive Nd:YAG lasers are used in conventional photoacoustic tomography (PAT) systems making them difficult to translate into clinics. Moreover, real-time imaging is not feasible when single-element ultrasound ...
A linear programming model for selection of sparse high-dimensional multiperiod portfolios
This paper studies the mean-variance (MV) portfolio problems under static and dynamic settings, particularly for the case in which the number of assets (p) is larger than the number of observations (n). We prove that the ...
Avenging Christchurch Terror : Indonesian Militant Responses
The March 2019 massacre at two mosques in Christchurch, New Zealand by a white supremacist has sparked retaliatory messages from Islamist militants in Indonesia. Outrage from the self-proclaimed Islamic State (IS) and its ...
Post-Lee Kuan Yew World : Is His Strategic Vision Still Relevant?
Singapore’s founding prime minister Lee Kuan Yew shaped the country’s foreign policy since its independence in 1965. But the world has changed much with the shifting geopolitical balance of power and disruptions caused by ...
21st Century Military Modernisation : Its Challenges
When a military organisation modernises its combat capabilities, it is natural to expect the new capabilities to be better than the old ones. This improvement is typically measured in terms of lethality. However, lethality ...
Singapore’s Total Defence : Overcoming Complacency
The absence of terror attacks in Singapore has led many Singaporeans to become complacent about the threat landscape. This could in turn, undermine national crisis preparedness. How can Singaporeans avoid this complacency mindset?
Vision-based flexible leader-follower formation tracking of multiple nonholonomic mobile robots in unknown obstacle environments
This brief investigates the flexible leader-follower formation tracking problem for a group of nonholonomic mobile robots, while most of the formation control related work in the literature focuses on the rigid formation. ...
Innovation-driven industrial green development : the moderating role of regional factors
Industrial green development (IGD) is a critical response to the over-consumption of natural resources and pollution caused by modern industry. Innovation-driven IGD has generated great interest in recent years. However, ...
