Introduction Acoustic scanner noise during image acquisition is a well-known problem in functional MRI (fMRI). The noise is created by gradient coil switching and causes an unwanted BOLD signal in the auditory cortex [1]. Most of the time, echo-planar imaging (EPI) is used for fMRI. However, this sequence produces high acoustic noise due to fast switching of trapezoidal gradients. The sound pre...

Drought analysis via the Standardized Precipitation Index (SPI) and Evapotranspiration (SPEI) is necessary for effective water resource management in Sarawak, Malaysia. Rainfall best indicator of a drought, but temperature also significant because it controls evaporation condensation. This study examined drought periods state Sarawak using SPI SPEI based on monthly precipitation data from thirt...

Introduction: Susceptibility-weighted imaging (SWI) is a newly developed approach to enhance contrast between tissues with different magnetic susceptibilities [1]. SWI takes advantage of the high sensitivity of NMR phase images to tissue susceptibility differences, and enhances image contrast in magnitude images using NMR phase images as masks. In addition to its initial application for imaging...

Drought as a natural but temporary imbalance of water availability is the interaction between natural environment and human life resulting in diminished water resources availability and reduced carrying capacity of the ecosystems. Drought indices are essential elements for an efficient drought monitoring system. These indices make the transforming information of climatic anomalies easier and al...
