A large number of long non-coding RNAs (lncRNAs) have been identified over the past decades. Accumulating evidence proves that lncRNAs play key roles in various biological processes. However, the majority of the lncRNAs have not been functionally characterized. The annotation of lncRNA functions has become an area of focus in the fields of biology and bioinformatics. In this paper, we develop a global...
Identifying the interactions between proteins and Long non-coding RNAs (lncRNAs) can provide valuable clues for understanding the mechanisms and physiological functions of lncRNAs. In this work, we propose a computational method, PLIPCOM, which can accurately detect protein-lncRNA interactions by integrating two groups of network features. Low dimensional diffusion characteristics and HeteSim features...

An electro-optic chaos generator is proposed based on phase modulation to intensity modulation conversion and an analog-digital hybrid feedback loop. The analog part takes the digital sequences from shift registers as input and converts them into analog noise like signal, from which new bits are determined. The effective bandwidth and complexity of the output analog signal can reach a high level with...
We propose a novel structure of optoelectronic oscillator (OEO) based on a microwave photonics filter (MPF), and this MPF is implemented by phase modulation to intensity modulation conversion and a heterogeneous multicore fiber. In our scheme, the periodicity of the generated finite impulse response (FIR) filter by using the multicore fiber is broken by the phase modulation to intensity modulation...

We consider the scenario where a cloud service provider (CSP) operates multiple geo-distributed datacenters to provide Internet-scale service. Our objective is to minimize the total electricity and bandwidth cost by jointly optimizing electricity procurement from wholesale markets and geographical load balancing (GLB), i.e., dynamically routing workloads to locations with cheaper electricity. Under...
