complementary metal-oxide semiconductor (cmos) technology has been the industry standard to implement very large scale integrated (vlsi) devices for the last two decades. due to the consequences of miniaturization of such devices (i.e. increasing switching speeds, increasing complexity and decreasing power consumption), it is essential to replace them with a new technology. quantum-dot cellular...

we have successfully fabricated and tested a high temperature superconducting sigma-delta A/D converter. The quantizer is a balanced comparator that has been characterized separately in two temperature regimes. The circuits have been fabricated with ramp edge junctions with a PrBaCuGaO-barrier on a buried ground plane. For the current to voltage conversion in the sigma-delta converter we fabric...

Fig. 3. Simulated dependences of the measured flip angle on φ0 in the weak (a) and strong (b-d) spoiling regimes for n=5 (a,b: parameters from Fig. 2); n=4 (c: TR1/TR2=20/80 ms, AG1/AG2= 204/816 mT·ms/m); and n=3 (d: TR1/TR2=20/60 ms, AG1/AG2=255/765 mT·ms/m). Black and gray lines correspond to the standard (1,2) and modified (3) RF spoiling schemes. For plots (b-d), the constant spoiler area i...

In this work, thermal cycling (T/C) reliability of anisotropic conductive film (ACF) flip chip assemblies having various chip and substrate thicknesses for thin chip-on-board (COB) packages were investigated. In order to analyze T/C reliability, shear strains of six flip chip assemblies were calculated using Suhir’s model. In addition, correlation of shear strain with die warpage was attempted....

Introduction Steady state free precession (SSFP) imaging is used in widespread applications such as breath-hold MRI examinations of the abdomen and cardiac due to its very high signal-sampling efficiency and good tissue contrast. SSFP imaging at a high static field strength of 3 T and greater often suffers from specific absorption rate (SAR) problems because a high flip angle and short repetiti...

The passive transbilayer movement-flip-flop-was investigated on planar bilayer lipid membranes (BLMs), containing myristic, stearic, or linoleic long-chain fatty acids (FA). In response to a transbilayer pH gradient, a difference in the surface charges between inner and outer leaflets appeared. Because the BLM was formed from FA and neutral lipid, a surface potential difference was originated s...

Low scaling technology makes a significant reduction in dimension and supply voltage, and lead to new challenges about power consumption such as increasing nodes sensitivity over radiation-induced soft errors in VLSI circuits. In this area, different design methods have been proposed to low power flip-flops and various research studies have been done to reach a suitable hardened flip-flops. In ...

Motivated by higher homological algebra, we associate quivers to triangulations of even-dimensional cyclic polytopes and prove two results showing what information about the triangulation is encoded in quiver. We first show that cut Iyama Oppermann correspond precisely 2d-dimensional without interior (d+1)-simplices. This implies these form a connected subgraph flip graph. Our second result sho...
