We demonstrate a four-user 10-Gb/s spectrally phasecoded optical code-division multiple-access system via nonlinear processing with ultralow power ( 30 fJ/bit). Full interference suppression is achieved in a time-slotted scheme without the need for chip-level coordination and synchronous detection. Performance degradation caused by pulse overlap between(More)
Maintenance of genomic stability is essential for normal organismal development and is vital to prevent diseases such as cancer. As genetic information is packaged into chromatin, it has become increasingly clear that the chromatin environment plays an important role in DNA damage response. However, how DNA repair is controlled by epigenetic mechanisms is(More)
The histone demethylase PHF8 has been implicated in multiple pathological disorders, including X-linked mental retardation and tumorigenesis. However, it is not clear how the abundance and function of PHF8 are regulated. Here, we report that PHF8 physically associates with the deubiquitinase USP7. Specifically, we demonstrated that USP7 promotes(More)
Although SIRT7 is a member of sirtuin family proteins that are described as NAD(+)-dependent class III histone deacetylases, the intrinsic enzymatic activity of this sirtuin protein remains to be investigated and the cellular function of SIRT7 remains to be explored. Here we report that SIRT7 is an NAD(+)-dependent histone desuccinylase. We show that SIRT7(More)
Defective centrosome duplication is implicated in microcephaly and primordial dwarfism as well as various ciliopathies and cancers. Yet, how the centrosome biogenesis is regulated remains poorly understood. Here we report that the X-linked deubiquitinase USP9X is physically associated with centriolar satellite protein CEP131, thereby stabilizing CEP131(More)
In order to improve the communication efficiency of ForCES transport mapping layer (ForCES TML), the paper proposes an evaluation model based on communication model of TML. In the model ,it tries to separate the communication process into two different stages: connection-setup and data-transmission stage. In both of them, we analysis the performance factors(More)
