Interjoint reflex function of the insect leg contributes to postural control at rest or to movement control during locomotor movements. In the stick insect (Carausius morosus), we investigated the role that sensory signals from the femoral chordotonal organ (fCO), the transducer of the femur-tibia (FT) joint, play in patterning motoneuronal activity in the(More)
Coordination of motor output between leg joints is crucial for the generation of posture and active movements in multijointed appendages of legged organisms. We investigated in the stick insect the information flow between the middle leg femoral chordotonal organ (fCO), which measures position and movement in the femur-tibia (FT) joint and the motoneuron(More)
This paper presents the first demonstration of a " zero-undercut " precision formation of ultrafine-line copper conductor patterns for redistribution layers (RDL) and thin film RF passives. This is accomplished by using a highly-anisotropic and uniform copper plasma-etching process to remove the seed layer with no lateral etching of the copper patterns,(More)
Plasma-assisted oxidation, anodization, and nitridation of silicon have been performed in microwave, rf, and dc plasmas with a variety of reactor configurations and a range of plasma densities. Compared to thermal processes at equivalent substrate temperatures, film growth rates are accelerated by the plasma-enhanced generation of reactive chemical species(More)
Amphiphobic wood has successfully been fabricated using a combination of O2 plasma surface activation and coating of pre-hydrolyzed methyltrimethoxysilane (MTMS). The effect of O2 plasma activation on surface chemistry and surface roughness was investigated using X-ray photoelectron spectroscopy and laser scanning confocal microscope profilometry,(More)
iii ACKNOWLEDGEMENTS I would like to make special thanks to my advisor Elsa Reichmanis who gave me remarkable opportunities by allowing research in the group. I will remember her as a person with deep patience and understanding. Her optimism and support were great cheers to me. Also I share thanks to my committee, Prof. and Yulin Deng, whom I am very proud(More)
To my parents iii ACKNOWLEDGEMENTS I am deeply grateful to my advisor, Dr. Meindl, for his guidance, motivation, and inspiration. I thank my committee members Dr. for many motivating and spirited discussions. I thank former GSI group members Azeez Bhavnagarwala, Keith Bowman, and Ragu Venkatesan, for many inspiring discussions. I thank Blanca Austin for(More)
