Stress‚ the disruption of the homeostatic balance by internal or external influences‚ is inherent‚ inevitable and exists in every stages of life‚ starting as early as the fetal stage till one’s death. In particular‚ early life stress (ELS) has come to light in recent years as it is becoming more prevalent and epidemiological studies have shown that ELS increases one’s vulnerability to subsequent stressors‚ leading to a multitude of stress-related neuropsychiatric disorders such as depression and

A Power Line Communication Explained (1984) Challenges and Technologies Abstract This paper reviews the sources of attenuation‚ noise and distortion encountered when communicating over AC power wiring. Various technologies which have been used to address these challenges‚ such as spread spectrum and digital signal processing‚ are then examined in light of the known channel conditions. Introduction While the idea of sending communication signals on the same pair of wires as are used for

to do this. Code Division Multiple Access is a new technology used in wireless communication devices. This technology made its commercial debut in the early nineties. Significant advantage of the CDMA is the fact that unlike other modulation schemes it does not have to allocate part of the frequency for each user. It allocates whole frequency spectrum to each user‚ distinguishing each signal with the unique pseudo-random sequence. CDMA stands for "Code Division Multiple

Amplitude Modulation – A method of signal transmission in which the amplitude of the carrier is varied in accordance with the signal. With respect to optical fiber cabling‚ the modulation is done by varying the amplitude of a light wave‚ common in analog/RF applications. 9.

J. S. Bach and the Second Brandenburg Concerto In December 1917‚ Johann Sebastian Bach began working as Prince Leopold of Cothen’s Kappelmeister (German: “chapel master‚” director of music)‚ tasked with composing for celebrations and holidays. A lover of music‚ the prince held Bach in high esteem; paying Bach more than twice the salary of his predecessor. Restricted by the chapel’s low-quality organ‚ Bach negotiated for new instruments in Carlsbad and Berlin‚ traveling with the prince throughout
