TL;DR: In this paper, an active-matrix display with 64 × 64 pixels, each driven by a thin-film transistor with a solution-processed polymer semiconductor, is described.
Abstract: The handling of grey levels by these large displays paves the way for electronic paper. The main advantages of using soluble semiconductive polymers in microelectronic devices are ease of processing1,2,3 and mechanical flexibility4. Here we describe an active-matrix display with 64 × 64 pixels, each driven by a thin-film transistor with a solution-processed polymer semiconductor. In a significant step towards low-cost flexible displays, this polymer-dispersed liquid-crystal arrangement gives a reflective, low-power display with paper-like contrast, which can handle 256 grey levels while being refreshed at video speed.

TL;DR: The data identify a downstream effector pathway that links Myc directly to cell cycle progression and suggests that cyclin D2 is repressed in a histone deacetylase‐dependent manner in quiescent cells.
Abstract: Ectopic expression of Myc induces Cdk2 kinase activity in quiescent cells and antagonizes association of p27 kip1 with Cdk2. The target gene(s) by which Myc mediates this effect is largely unknown. We now show that p27 is rapidly and transiently sequestered by cyclin D2–Cdk4 complexes upon activation of Myc and that cyclin D2 is a direct target gene of Myc. The cyclin D2 promoter is repressed by Mad–Max complexes and de‐repressed by Myc via a single highly conserved E‐box element. Addition of trichostatin A to quiescent cells mimics activation of Myc and induces cyclin D2 expression, suggesting that cyclin D2 is repressed in a histone deacetylase‐dependent manner in quiescent cells. Inhibition of cyclin D2 function in established cell lines, either by ectopic expression of p16 or by antibody injection, inhibits Myc‐dependent dissociation of p27 from Cdk2 and Myc‐induced cell cycle entry. Primary mouse fibroblasts that are cyclin D2‐deficient undergo accelerated senescence in culture and are not immortalized by Myc; induction of apoptosis by Myc is unimpaired in such cells. Our data identify a downstream effector pathway that links Myc directly to cell cycle progression.

TL;DR: In this article, forced oscillations in a circuit with non-linear resistance were studied. But the authors focused on the reception with reactive triodes. And they did not consider the effects of the reactive triode on the circuit.

TL;DR: An overview of current industrial practices as well as academic research in core-based IC design is provided and the challenges for future research are described.
Abstract: Advances in semiconductor process and design technology enable the design of complex system chips. Traditional IC design in which every circuit is designed from scratch and reuse is limited to standard-cell libraries, is more and more replaced by a design style based on embedding large reusable modules, the so-called cores. This core-based design poses a series of new challenges, especially in the domains of manufacturing test and design validation and debug. This paper provides an overview of current industrial practices as well as academic research in these areas. We also discuss industry-wide efforts by VSIA and IEEE P1500 and describe the challenges for future research.

TL;DR: This work has shown that the paraperspective factorization method can be applied to a much wider range of motion scenarios, including image sequences containing motion toward the camera and aerial image sequences of terrain taken from a low-altitude airplane.
Abstract: The factorization method, first developed by Tomasi and Kanade (1992), recovers both the shape of an object and its motion from a sequence of images, using many images and tracking many feature points to obtain highly redundant feature position information. The method robustly processes the feature trajectory information using singular value decomposition (SVD), taking advantage of the linear algebraic properties of orthographic projection. However, an orthographic formulation limits the range of motions the method can accommodate. Paraperspective projection, first introduced by Ohta et al. (1981), is a projection model that closely approximates perspective projection by modeling several effects not modeled under orthographic projection, while retaining linear algebraic properties. Our paraperspective factorization method can be applied to a much wider range of motion scenarios, including image sequences containing motion toward the camera and aerial image sequences of terrain taken from a low-altitude airplane.
