Have We Been Hebbing Down the Wrong Path?

چکیده
In this issue of Neuron, Stepanyants, Hof, and Chklovskii derive a simple mathematical formula to calculate, from measurable anatomical parameters, the capacity for neuronal wiring plasticity involving local synaptic rearrangements. Their work provides a deeper understanding of the potential contribution of structural plasticity to learning and memory.

Exploiting the Prefetching Effect Provided by Executing Mispredicted Load Instructions
As the degree of instruction-level parallelism in superscalar architectures increases, the gap between processor and memory performance continues to grow requiring more aggressive techniques to increase the performance of the memory system. We propose a new technique, which is based on the wrong-path execution of loads far beyond instruction fetch-limiting conditional branches, to exploit more ...
متن کاملInvestigating the Effects of Wrong-Path Memory References in Shared-Memory Multiprocessor Systems
Uniprocessor studies have shown that wrong-path memory references pollute the caches by bringing in data that are not needed for the correct execution path and by evicting useful data or instructions. Additionally, they also increase the amount of cache and memory traffic. On the positive side, however, they may have a prefetching effect for loads and instructions on the correct path. While the...
متن کاملHuman Papillomavirus and Cancer - Immunological Consequences of MHC Class I Down-Regulation
Few studies have been conducted on the causative factors associated with the development of cancer. Infection by high risk human papillomaviruses (HPVs) have been implicated as causative agents in a variety of cancers. HPV is capable of evading immune system and establishing persistent infections. Prolonged infection and lesion maintenance are associated with higher risk of neoplastic progressi...
متن کاملWrong Path Events: Exploiting Illegal and Unusual Program Behavior for Early Misprediction Recovery
Control and data speculation are widely used to improve processor performance. Correct speculation can reduce execution time, but incorrect speculation can lead to increased execution time and greater energy consumption. This paper proposes a mechanism to leverage unexpected program behavior, called wrong-path events, that occur during periods of incorrect speculation. A wrong-path event is an ...
متن کاملApplication of Molecular DNA Markers (STRs) in Molecular Diagnosis of Down Syndrome in Iran
Down syndrome is one of the most common causes of mental retardation observed in approximately 1/700 live birth. The use of two or more STR markers related to chromosome 21 facilitates the diagnosis of Down syndrome within about six hours from the collection of the samples. This is the first study has been performed in Iranian population to assess the diagnostic value of using small tandem repe...
