The relationships between individuals in various systems are always described by networks. Recently, the quick development of computer science makes it possible to study the structures of those super-complex networks in many areas including sociology (Xuan et al., 2009; Xuan, Du & Wu, 2010a), biology (Barabási & Oltvai, 2004; Eguíluz et al., 2005), physics (Dorogovtsev et al., 2008; Rozenfeld e...

The phytochemistry of the genus Piper is rich in terms of numbers of compounds discovered, but given the diversity of this genus and the intraspecific diversity of secondary metabolites in those species that have been examined, Piper chemistry has not been adequately investigated. The natural products chemistry that has been elucidated is well documented and has been the subject of extensive re...

Tensin is a focal adhesion molecule that binds to actin filaments through its N terminus (Lo et al., 1994a; Lo et al., 1994b; Chuang et al., 1995). In addition, it contains two functional motifs, including a Src homology domain 2 (SH2) and a phosphotyrosine binding (PTB) domain (Davis et al., 1991; Chen et al., 2000; Chen et al., 2002). This conserved domain structure gives significant clues to...

Recently, a general polarimetric model-based decomposition framework was proposed by Chen et al., which addresses several well-known limitations in previous decomposition methods and implements a simultaneous full-parameter inversion by using complete polarimetric information. However, it only employs four typical models to characterize the volume scattering component, which limits the paramete...

Recently, Chen et al (2011 New J. Phys. 13 083018) presented experimental results, accompanied by quantum-mechanical analysis, showing that the quantum interference behavior of Bell states could be simulated in a modified Mach–Zehnder interferometer whose inputs are pseudothermal light beams obtained by passing laser light through a rotating ground-glass diffuser. Their experiments and their th...

In this paper, we develop an approach for optimizing the explicit binomial confidence interval recently derived by Chen et al. The optimization reduces conservativeness while guaranteeing prescribed coverage probability. 1 Explicit Formula of Chen et al. Let X be a Bernoulli random variable defined in probability space (Ω,F ,Pr) with distribution Pr{X = 1} = 1 − Pr{X = 0} = p ∈ (0, 1). It is a ...

Covered lagoon biodigesters (CLB) have been widespread in Brazil the treatment of pig manure. However, quantification biogas production CLB using mathematical models is still limited and scarce. This study aimed to evaluate compare six models—Chen-Hashimoto (Chen, 1983), CETESB (2006), COD Conversion (Chernicharo, 2016), IPCC Deng (Deng et al., 2014), modified Stover-Kincannon (Yu 1998)—usually...

Correction for ‘A hollow urchin-like metal–organic framework with Ni–O-cluster SBUs as a promising electrode an alkaline battery–supercapacitor device’ by Tianqi Chen et al., Inorg. Chem. Front. , 2023, 10 2380–2386, https://doi.org/10.1039/D3QI00123G.

The limits for the predictability of the El Niño–Southern Oscillation (ENSO) have been long discussed. Even when ENSO prediction skill is expected to be limited, questions remain as to which are the controlling factors. The role of atmospheric noise for ENSO initiation, the growth of initial errors and inadequate models have been identified as key elements (e.g., Chen et al. 2004; Chen and Cane...
