In this work, we will review possible technology options for next generation wireless communication. Next to the introduction of specific device architectures and materials, dissimilar from standard ...Si CMOS, the challenge will lie in the co-integration of these non-Si technologies with CMOS to enable power efficient systems with high performance, in this case high speed and output power, and reduced form factor. Next to monolithic integration, sequential 3D, currently been investigated for LOGIC density scaling, can be one of the enablers, allowing to combine technologies with very different needs at a finer grain and thus higher density than traditional 3D-SOC and 3D-IC technologies.
We review our recent studies of oxide traps in InGaAs MOS gate stacks for novel high-mobility n-channel MOSFETs. We discuss and correlate various trap characterization techniques such as Bias ...Temperature Instability, defect Capture-Emission-Time maps (applied here to InGaAs devices), Random Telegraph Noise, hysteresis traces, multi-frequency C-V dispersion, all performed on a variety of device test vehicles (capacitors, planar MOSFETs, finFETs, nanowires). Finally we demonstrate guidelines for developing sufficiently reliable IIIV gate stacks.

We demonstrate a system for capturing multi-thousand frame-per-second (fps) video using a dense array of cheap 30 fps CMOS image sensors. A benefit of using a camera array to capture high-speed video ...is that we can scale to higher speeds by simply adding more cameras. Even at extremely high frame rates, our array architecture supports continuous streaming to disk from all of the cameras. This allows us to record unpredictable events, in which nothing occurs before the event of interest that could be used to trigger the beginning of recording. Synthesizing one high-speed video sequence using images from an array of cameras requires methods to calibrate and correct those cameras' varying radiometric and geometric properties. We assume that our scene is either relatively planar or is very far away from the camera and that the images can therefore be aligned using projective transforms. We analyze the errors from this assumption and present methods to make them less visually objectionable. We also present a new method to automatically color match our sensors. Finally, we demonstrate how to compensate for spatial and temporal distortions caused by the electronic rolling shutter, a common feature of low-end CMOS sensors.
Mechanisms of the myelotoxic action of doxorubicin associated with changes in the expression and functional activity of P2X7 receptors have been assessed. The acute and subacute exposure of bone ...marrow cells to doxorubicin in vivo changed the expression of P2X7, altered the intracellular and extracellular ATP concentrations, and modulated the process of programmed cell death. These changes were associated with transformed susceptibility of hemopoietic cells to the apoptogenic action of ATP. Various possible mechanisms of realization of the apoptogenic action of ATP during acute and subacute exposure to doxorubicin are discussed.
Muds from harbors and embayments are sintered to produce high-Quality construction ceramics. Structural composition and mechanical properties of the aggregate are determined. The environmental ...consequences of using dredge soil for making bricks are discussed.
The effects of glycolysis metabolites and some amino acids on the activity of bovine brain enolase have been studied. The inhibiting effect of glycolysis metabolites, of which two (2-phosphoglycolate ...and glyceraldehyde 3-phosphate) may be functionally significant, has been demonstrated. The action mechanisms of these compounds within a range of physiological concentrations as well as the combined effect of glyceraldehyde 3-phosphate and phosphoglyceromutase on enolase activity have been investigated.
