An Optical Frequency Comb has been numerically generated using a Silicon Nitride Waveguide. Geometrical parameters have been optimized for all normal dispersion profiles. Using a dual-wavelength pump around 1.55 μm in the ...

Job stress and management process alignment can influence work attitudes and productivity; however, there is still no empirical evidence addressing how these factors influence customer service quality in banking industry. ...

new D-shaped photonic crystal fiber (PCF) based surface plasmon resonance (SPR) sensor has been introduced for refractive index (RI) sensing. The proposed sensor is designed and numerically investigated by the Full Vector ...

Detection and classification of leaf and crop diseases in a traditional way is a very laborious task as it involves a significant amount of physical work, huge expert manpower, and valuable time. Automatic systems are more ...

This work presents an anisotropic cylindrical source’s gravitational expansion and collapse with the cosmological constant. For this purpose, we use the cylindrically symmetric metric and energy–momentum tensor to achieve ...

The objective of the study was to determine the impact of unethical behavior of the officials of different departments on citizens’ trust with reference to good governance in Pakistan. The livelihood, way of life, and ...

Geopolitical risks and uncertainty negatively affect the economy and environmental quality. High geopolitical risks and high uncertainty increase carbon emission intensity by increasing dependence on fossil fuels. However, ...

We examine the key drivers behind management decisions on share repurchase from various theoretical perspectives, including the free cash flow theory and the signaling theory/hypothesis. Specifically, we investigate the ...

Anaemia among preeclamptic (PE) women is a major undefined health issue in Bangladesh. This study explored the risk factors associated with anaemia and mapped the regional influences to understand the geographical inequalities. ...

Pulmonary Tuberculosis (PTB) is a significant global health issue due to its high incidence, drug resistance, contagious nature, and impact on people with compromised immune systems. As mentioned by the World Health ...
