Umweltreport DDR des IÖW: Ökologischer Umbau der DDR

BMI1, ATM and DDR

The polycomb group protein BMI1 is a component of the polycomb repressive complex 1 (PRC1). Although lacking enzymatic activity, BMI1 makes an important contribution to the intrinsic E3 ubiquitin ligase activity of PRC1 via binding of the catalytic subunit RING2. PRC1 catalyzes mono-ubiquitination of histone H2A at lysine 119 (H2AK119Ub), a well-recognized epigenetic marker associated with gene...

Cell-ECM interactions control DDR

Fundamental to an improvement of cancer cure rates is a better understanding of the underlying molecular mechanisms driving resistance to standard treatments such as radioand chemotherapy. A powerful and promising approach to sensitize cancer cells to therapy is represented by Paul Ehrlich ́s old and still up-to-date concept of the “magic bullet”. Reviewing the complexity of the “hallmarks of ca...

DDR and the Complexity of Contemporary Conflict

A Low Power DDR SDRAM Controller Design

This paper work leads to a working implementation of a Low Power DDR SDRAM Controller that is meant to be used as a reference for future implementations. . The DDR SDRAM is an enhancement to the traditional Synchronous DRAM. It supports data transfers on both edges of each clock cycle, effectively doubling the data throughput of the memory device. In this project Low Power Techniques are propos...

DDR SDRAM CHARACTERISTIC IMPEDANCE and PCB Design

As clock speeds increase and rise times decrease, the importance of maintaining good signal integrity in electronic products has assumed increasing importance and visibility. This is particularly true of the ubiquitous products incorporating DDR SDRAM devices. The characteristic impedance of the circuit board under design is usually the first, and arguably the most important, design parameter. ...
