SP100 is an antiviral protein that restricts the productive stage of human papillomavirus(HPV)and multiple other viruses,and viruses in turn block sUMO-1-mediated stabilization of SP100 and promotes its degradation(Table S1).Interferon(IFN)signaling could still produce more SP100 through transcription to counteract viruses.1 Viruses also disable the transcriptional up-regulation of SP100 to achieve persistent infection in hosts.

The single particle energies obtained in a Kohn-Sham density functional theory(DFT) calculation are generally known to be poor approximations to electron excitation energies that are measured in transport,tunneling and spectroscopic experiments such as photo-emission spectroscopy. The correction to these energies can be obtained from the poles of a single particle green's function derived from a many-body perturbation theory. From a computational perspective, the accuracy and efficiency of such an approach depends on how a self energy term that properly accounts for dynamic screening of electrons is approximated. The g_0W_0 approximation is a widely used technique in which the self energy is expressed as the convolution of a noninteracting green's function(g_0) and a screened Coulomb interaction(W_0) in the frequency domain. The computational cost associated with such a convolution is high due to the high complexity of evaluating W_0 at multiple frequencies. In this paper, we discuss how the cost of g_0W_0 calculation can be reduced by constructing a low rank approximation to the frequency dependent part of W_0. In particular, we examine the effect of such a low rank approximation on the accuracy of the g_0W_0 approximation. We also discuss how the numerical convolution of g_0 and W_0 can be evaluated efficiently and accurately by using a contour deformation technique with an appropriate choice of the contour.

In this paper, we use the fractional complex transform and the （g＇/g）-expansion method to study the nonlinear fractional differential equations and find the exact solutions. The fractional complex transform is proposed to convert a partial fractional differential equation with Jumarie＇s modified Riemann-Liouville derivative into its ordinary differential equation. It is shown that the considered transform and method are very efficient and powerful in solving wide classes of nonlinear fractional order equations.

The problem of eliminating edge-chipping at the entrance and exit of the hole while drilling brittle materials is still a challenging task in different industries. grinding- aided electrochemical discharge machining （g-ECDM） is a promising technology for drilling advanced hard-to-ma- chine ceramics, glass, composites, and other brittle mate- rials. Edge-chipping at the entrance of the hole can be fully eliminated by optimizing the machining parameters of g-ECDM. However, edge-chipping at the exit of the hole is difficult to eliminate during the drilling of ceramics and glass. This investigation suggests some practical ways to reduce edge-chipping at the exit of the hole. For this pur- pose, a three-dimensional finite element model was developed, and a coupled field analysis was conducted to study the effect of four parameters, i.e., cutting depth, support length, applied voltage, and pulse-on time, on the maximum normal stress in the region where the edge- chipping initiates. The model is capable of predicting the edge-chipping thickness, and the results predicted by the model are in close agreement with the experiment results. This investigation recommends the use of a low voltage and low pulse-on time at the hole entrance and exit when applying g-ECDM to reduce the edge-chipping thickness. Moreover, the use of a full rigid support in the form of a base plate or sacrificial plate beneath the workpiece can postpone the initiation of chipping by providing support when the tool reaches the bottom layer of the workpiece, thereby reducing the edge-chipping thickness.

Unusual polarization properties of the high galactic latitude supernova remnant (SNR) g4.8+6.2 are reported. The percentage polarization is larger than 70% over the two main shells of g4.8+6.2 at 1400MHz. It is the second SNR with such high polarization at such a low frequency among the known 225SNRs. We show that this is very unusual for an SNR. Its morphology and polarization are very similar to those of the supernova remnant DA530 (g93.0+6.5), which is another high galactic latitude SNR.

Poly（2-hydroxyethylmethacrylate） chains were grafted onto the backbone of agar using a microwave assisted method involving a combination of microwave irradiation and ceric ammonium nitrate to initiate the grafting reaction. The synthesized graft copolymers were characterized by intrinsic viscosity measurements, Fourier transform infrared spectroscopy, elemental analysis （C, H, N, O and S） and scanning electron microscopy. Ag-g-P （HEMA）-2 showed a much higher flocculation efficacy than agar. The optimized dosage of flocculation for Ag-g-P （HEMA）-2 in the wastewater was found to be 0.75 ppm. Compared to agar, Ag-g-P（HEMA）-2 was found to considerably reduce the pollutant load in the wastewater.
