CT-guided needle biopsy is an important minimally invasive procedure to obtain tissue cells from lung nodules for cytological lung cancer diagnosis. The current procedure requires a specially-trained interventional ...

This thesis presents a design methodology of a low-power and low-noise integrated front-end readout circuits for radiation detection. Since a charge sensitive amplifier (CSA) and a pulse shaper are essential circuit units ...

I present design of a new ultra-sensitive data acquisition system for fluorescence detection applications. Based on single photon detection, the developed system comprises a unique single photon spectrometer with high ...

There are two principal reasons why we age: 1) the toxicity of oxygen species; 2) the continuous degradation of collagen by groups of enzymes such as the matrix metalloproteinases (MMPs). The MMPs are a group of more than ...

Despite extensive research in last 40 years, the treatment of TB is still limited to a cocktail of classical drugs that mostly target cell wall biosynthesis, DNA coiling, transcription, translation. Knowing the bacterial ...

Infectious diseases, caused by pathogenic biological agents, are the leading causes of death worldwide, especially in low-income countries. Two such pathogenic bacteria that are our centers of interest are Staphylococcus ...

In this study, heterogeneous chemical reactions between trace gases and atmospheric soot particles are investigated using a particle-resolved aerosol model. The model accounts for physical and chemical processes in the ...

Researchers have reported diverse mechanical properties (Young's modulus) of human tooth enamel from experiments and finite element simulations, because of the complicated microstructure, which contains variations in crystal ...

The ecological and evolutionary study of plant invasion processes is of exceeding importance in today's changing environment. However, few studies have addressed the impact of natural selection on invasive plant species. ...
