Stochastic Stabilization of Dual-Layer Rumor Propagation Model with Multiple Channels and Rumor-Detection Mechanism.

With the development of information technology, individuals are able to receive rumor information through various channels and subsequently act based on their own perceptions. The significance of the disparity between media and individual cognition in the propagation of rumors cannot be underestimated. In this paper, we establish a dual-layer rumor propagation model considering the differences in individual cognition to study the propagation behavior of rumors in multiple channels.

Evaluation of the Effectiveness of Active and Passive Safety Measures in Preventing Ship-Bridge Collision.

The risk of ship-bridge collisions should be evaluated using advanced models to consider different anti-collision and bridge-protection measures.

A Novel Epidemic Model Base on Pulse Charging in Wireless Rechargeable Sensor Networks.

As wireless rechargeable sensor networks (WRSNs) are gradually being widely accepted and recognized, the security issues of WRSNs have also become the focus of research discussion. In the existing WRSNs research, few people introduced the idea of pulse charging. Taking into account the utilization rate of nodes' energy, this paper proposes a novel pulse infectious disease model (SIALS-P), which is composed of susceptible, infected, anti-malware and low-energy susceptible states under pulse charging, to deal with the security issues of WRSNs.

A Modified Sparrow Search Algorithm with Application in 3d Route Planning for UAV.

The unmanned aerial vehicle (UAV) route planning problem mainly centralizes on the process of calculating the best route between the departure point and target point as well as avoiding obstructions on route to avoid collisions within a given flight area. A highly efficient route planning approach is required for this complex high dimensional optimization problem. However, many algorithms are infeasible or have low efficiency, particularly in the complex three-dimensional (3d) flight environment.

A Novel Epidemic Model for Wireless Rechargeable Sensor Network Security.

With the development of wireless rechargeable sensor networks (WRSNs ), security issues of WRSNs have attracted more attention from scholars around the world. In this paper, a novel epidemic model, SILS(usceptible, nfected, ow-energy, usceptible), considering the removal, charging and reinfection process of WRSNs is proposed. Subsequently, the local and global stabilities of disease-free and epidemic equilibrium points are analyzed and simulated after obtaining the basic reproductive number R0.

Postoperative intensity-modulated radiation therapy reduces local recurrence and improves overall survival in III-N2 non-small-cell lung cancer: A single-center, retrospective study.

Purpose: To determine the postoperative effects of radiotherapy (PORT) on the local recurrence-free survival (LRFS) and overall survival (OS) of stage III-N2 non-small-cell lung cancer (NSCLC).

Materials And Methods: 183 patients with resected stage III-pN2 NSCLC from Hunan Cancer Hospital between 2013 and 2016 were divided into two groups for postoperative chemotherapy (POCT) (n = 105) or combination chemotherapy and radiotherapy (POCRT) (n = 78). The LRFS and OS were compared and the factors affecting local recurrence were illustrated in these two groups.

c-Fos over-expression promotes radioresistance and predicts poor prognosis in malignant glioma.

c-Fos is a major component of activator protein (AP)-1 complex. It has been implicated in cell differentiation, proliferation, angiogenesis, invasion, and metastasis. To investigate the role of c-Fos in glioma radiosensitivity and to understand the underlying molecular mechanisms, we downregulated c-Fos gene expression by lentivirus-mediated shRNA in glioma cell lines and subsequently analyzed the radiosensitivity, DNA damage repair capacity, and cell cycle distribution.

Structural basis for the immunomodulatory function of cysteine protease inhibitor from human roundworm Ascaris lumbricoides.

Immunosuppression associated with infections of nematode parasites has been documented. Cysteine protease inhibitor (CPI) released by the nematode parasites is identified as one of the major modulators of host immune response. In this report, we demonstrated that the recombinant CPI protein of Ascaris lumbricoides (Al-CPI) strongly inhibited the activities of cathepsin L, C, S, and showed weaker effect to cathepsin B.

[Rapid change in structure of Brachionus calyciflorus complex collected from Jiulian Pond and its ecological mechanism].

In order to investigate the rapid variation in the structure of Brachionus calyciflorus complex and the fitness traits of the two sibling species, the rotifers were collected once a week from Jiulian Pond during 16 July and 6 August, their COI genes were sequenced and analyzed, and their fitness parameters (average lifespan, net reproductive rate, intrinsic rate of population increase and proportion of sexual offspring) were calculated at 28 degrees C and 32 degrees C with 1.0 x 10(6), 3.0 x 10(6) and 5.

Modulation of dendritic cell function and immune response by cysteine protease inhibitor from murine nematode parasite Heligmosomoides polygyrus.

Modulation and suppression of the immune response of the host by nematode parasites have been reported extensively and the cysteine protease inhibitor (CPI or cystatin) is identified as one of the major immunomodulators. In the present study, we cloned and produced recombinant CPI protein from the murine nematode parasite Heligmosomoides polygyrus (rHp-CPI) and investigated its immunomodulatory effects on dendritic cell (DC) function and immune responses in mice. Bone-marrow-derived CD11c(+) DC (BMDC) that were exposed to rHp-CPI during the differentiation stage showed reduced MHC-II molecule expression compared with BMDC that were generated in normal culture conditions.

Aim: Since any relationship between hormonal and reproductive factors and risk of esophageal cancer is unclear, we investigated this question in Shandong province of China.

Methods: A hospital-based 1:1 matched case-control study was conducted from January 2008 to November 2010, with face to face interviews conducted for 132 cases and 132 controls. All cases recruited in this study were confirmed by endoscopy and histological examination.

The phenotype and function of naturally existing regulatory dendritic cells in nematode-infected mice.

Immunosuppression associated with chronic helminth infections has been documented in many studies and regulatory T (Treg) cells have been shown to mediate the nematode-induced immunosuppression, but the role of dendritic cells (DCs) in the induction of Treg cell response and immunosuppression has not yet been fully determined. We analysed the response and function of DCs in mesenteric lymph node (MLNs) of mice infected with a gastrointestinal nematode, Heligmosomoides polygyrus, and observed a substantial expansion of DCs in MLNs following the infection. The CD11c(+) DCs in MLNs of infected mice showed reduced expression of co-stimulatory molecules CD40, CD86 and MHC-II, and production of inflammatory cytokines IL-12 and IL-6.
