Flush+Flush: A Fast and Stealthy Cache Attack

Research on cache attacks has shown that CPU caches leak significant information. Proposed detection mechanisms assume that all cache attacks cause more cache hits and cache misses than benign applications and use hardware performance counters for detection. In this article, we show that this assumption does not hold by developing a novel attack technique: the Flush+Flush attack. The Flush+Flus...

FLUSH: A Flexible Lexicon Design

Approaches to natural language processing that use a phrasal lexicon have the advantage of easily handling linguistic constructions that might otherwise be extragrammatical. However, current phrasal lexicons are often too rigid: their phrasal entries fail to cover the more flexible constructions. FLUSH, for Flexible Lexicon Utilizing Specialized and Hierarchical knowledge, is a knowledge-based ...

A Cheap Flush-Out Latrine

Drawing to a Diamond flush.

In this issue of Blood, Dutt and colleagues address the selective effect of ribosomal protein haploinsufficiency on erythroid development observed in congenital Diamond-Blackfan anemia (DBA) and acquired 5q-syndrome. Their findings reveal a selective induction of p53 in the erythroid lineage in response to reduced expression of ribosomal proteins affected in these diseases. Moreover, the select...
