BACKGROUND The rapid growth of tumor parenchyma leads to chronic hypoxia that can result in the selection of cancer cells with a more aggressive behavior and death-resistant potential to survive and proliferate. Thus, identifying the key molecules and molecular mechanisms responsible for the phenotypic changes associated with chronic hypoxia has valuable(More)
—As operation frequencies and performance requirements of wireless devices increase, the resultant demands on the performance of passive components also increase. Miniaturiza-tion of inductive components for high frequency has been a key research area to address this issue; however, in general, minia-turized integrated inductors can suffer from low Q(More)
An integrated flexible inductor is realized for wireless transcutaneous power transmission to implantable devices. Our method uses a mechanically flexible inductor which can be less invasively implanted in, or more easily attached to, the human body. The inductor pair is used for wireless power transmission. The primary inductor is attached on the(More)
Induction coils were fabricated based on flexible printed circuit board for inductive transcutaneous power transmission. The coil had closed magnetic circuit (CMC) structure consisting of inner and outer magnetic core. The power transmission efficiency of the fabricated device was measured in the air and in vivo condition. It was confirmed that the CMC coil(More)
This paper reports on a thermoelectric generator (TEG) used for converting human body heat energy to electrical energy. The proposed TEG was composed of a polydimethylsiloxane (PDMS) substrate and thermocouples. The use of PDMS provides flexibility to the TEG and low thermal conductivity that helps minimize losses in the effective heat flowing through the(More)
The aim of this study was to compare the effects of spermatozoa separation techniques on sperm quality and in-vitro fertilization (IVF) results for cryopreserved bovine semen. Sephadex, glass wool and Percoll gradient separation techniques were used for sperm separation and sperm motility, morphology and membrane integrity were evaluated before and after(More)
This paper proposes the design and VLSI implement of high efficient Context-based Adaptive Variable Length Coding (CAVLC) encoder which adopted a modified Variable Length Coding (VLC) look up table technique and parallel processing. The proposed CAVLC encoder used upper and under buffer as input buffer to perform zigzag scanning with both way ordering.(More)
This paper presents the development of flexible electrocardiography (ECG) sensors using both a flexible printed circuit (FPCB) and microelectromechanical systems (MEMS) technology. By using FPCB technology, polymer-based ECG sensors of a bipolar Laplacian-type electrode were fabricated and their ECG measurement capability was examined by both implanting the(More)
The current study presents an organotypic rat midbrain slice culture that served as a consistent and informative framework, where the STN neurons and their interconnectivity were closely examined with respect to electrophysiological and pharmacological properties. From multi-electrode array recordings, it was found that the majority of STN neurons(More)
—This paper describes the design and VLSI implementation of high throughput deblocking filter which adopted hybrid filtering order, single port memory, and hierarchical memory structure. The proposed deblocking filter used upper and left buffer. Because of this, the number of access to constructed picture memory can be reduced. Moreover, we design the(More)
