Around 800,000 people fall prey to cyberattacks annually, most often by “malware”. Malware has the potential to become a destructive weapon in Cyber-world. It is a difficult task to manually thwart an assault by malware. It is crucial to properly categorize malware binaries in order to identify thei...

In many places in Vietnam central region, the fresh coastal sand dune aquifers have an interface with salty water below, so upon groundwater (GW) abstraction, there is a risk of salty water upconing to the abstraction facilities. With the same abstraction rate, the horizontal drains shall significan...

A D-shaped highly sensitive plasmonic resonance sensor for low refractive index (RI) detection is proposed in this work. Plasmonic material layer and the sensing layer have been placed outside of the fiber structure in order to sense the changes in refractive index of the surrounding medium. Titaniu...

Intro: Dengue epidemics impose considerable strain on healthcare resources. Real-time continuous and non-invasive monitoring of patients admitted to the hospital could lead to improved care and outcomes. We evaluated the performance of a commercially-available wearable (SmartCare) utilising photople...

A novel hollow core Kagome lattice photonic crystal fiber(PCF) has been designed and analyzed for terahertz (THz) wave guidance by pumping Xenon (Xe) gas inside the hollow core of the PCF. Using finite element method (FEM), optical properties have been simulated and optimized with different strut wi...

The ability of hyperbolic metamaterials to achieve sub-diffraction imaging via high- k wave propagation is intrinsically limited by a narrow operational bandwidth near Fabry-Perot resonances. We elucidate the physical origin of the image artifacts by first modeling the metamaterial slab as a cavity ...
