In this paper, we consider the scenario that a population-based algorithm is applied to a numerical optimization problem and a solution needs to be presented within a given time budget. Although a wide range of population-based algorithms, such as evolutionary algorithms, particle swarm optimizers, and differential evolution, have been developed and studied(More)
Protein phosphorylation plays a fundamental role in most of the cellular regulatory pathways. Experimental identification of protein kinases' (PKs) substrates with their phosphorylation sites is labor-intensive and often limited by the availability and optimization of enzymatic reactions. Recently, large-scale analysis of the phosphoproteome by the mass(More)
Carrier frequency offset (CFO) damages the orthogonality between sub-carriers and thus causes multiuser interference in uplink OFDMA/SC-FDMA systems. For a given CFO, such multiuser interference is mainly dictated by channel (sub-carrier) allocation, which also specifies the diversity gain of one user over multi-path channels. In particular, the positions(More)
In this paper, an iterative algorithm is constructed to solve the minimum Frobenius norm residual problem: min ∥∥∥(A1XB1 A2XB2)− (C1 C2)∥∥∥ over bisymmetric matrices. By this algorithm, for any initial bisymmetric matrix X0, a solution X can be obtained in finite iteration steps in the absence of roundoff errors, and the solution with least norm can be(More)
Protein sumoylation is an important reversible post-translational modification of proteins in the nucleus, and it orchestrates a variety of the cellular processes. Genome-wide analysis of functional abundance and distribution of Small Ubiquitin-related MOdifier (SUMO) substrates may shed a light on how sumoylation is involved in nuclear biological processes(More)
In the past decades, many theoretical results related to the time complexity of evolutionary algorithms (EAs) on different problems are obtained. However, there is not any general and easy-to-apply approach designed particularly for population-based EAs on unimodal problems. In this paper, we first generalize the concept of the takeover time to EAs with(More)
Due to its lower peak-to-average power ratio (PAPR) compared with orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA) has been recently accepted as the uplink multiple access scheme in the Long Term Evolution (LTE) of cellular systems by the Third Generation Partnership Project (3GPP). However,(More)
Web content structure is proposed to facilitate automatic web page adaptation in this paper. By identifying the logic relationship of web content based on layout information, web content structure effectively represents authors' presentation intention. An automatic top-down, tag-tree independent approach to detect web content structure is presented. It(More)
