Bundling has become an important operational tool for online retail platforms to attract consumers. Nevertheless, published empirical results on consumer behavior show that a bundle discount negatively influences the consumers’ perceived value of individual component products. We investigate how valuation discounts like these influence the online retail platforms’ decision optimization in bundling. Optimization models for mixed-joint and mixed-leader bundling are developed to analyze this effect. Based on the benchmark model of no-bundling, insightful implications are...

Background:Trigger point (TrP) acupuncture is commonly used to treat chronic non-specific low back pain (CNLBP). Evidence for the efficacy of most TrP acupuncture modalities is weak or lacking.Objective:To assess the effect of TrP acupuncture on pain, disability, gait and muscle activation in patients with CNLBP.Methods:From May 2019 to February 2020, a randomised, single-blind clinical trial was carried out involving 33 participants with CNLBP, divided into one of two intervention groups or a control group (n...

In China, a developing country, the car ownership level is much lower than that in developed countries, but transportation policies have been implemented to discourage car ownership and mitigate traffic congestion. However, car ownership (considered as car availability in this paper, meaning that an individual has access to a household private car) may influence travelers’ well-being. To highlight the interrelation between car ownership and travelers’ well-being, this paper develops a probit-based discrete-continuous model to analyze...

To evaluate and compare the blood lipid profile in retinal artery occlusion (RAO) and retinal vein occlusion (RVO). We included 82 RAO patients and 95 RVO patients in this retrospective case–control study. Controls were matched to RAO or RVO patients at a 1:1 ratio, respectively. Associated lipid variates were analyzed in multivariable logistic regression models. LDL-C (OR = 1.69), non-HDL-C (OR = 1.87), and ApoB (OR = 11.72) individually significantly increased the risk of RAO....

This study aimed to investigate the correlations between smartphone use, physical activity, and quality of life (QOL) among Chinese college students. We enrolled 6323 students who were chosen from three Chinese universities. All participants completed the World Health Organization QOL Scale-Brief, Smartphone Addiction Index, and Physical Activity Questionnaire-Short Form. Smartphone addiction was negatively related to QOL (β = −1.375, 95% CI [–1.442, –1.306]), whereas physical activity was positively related to QOL (β = .059, 95%...

Current predictors are largely unsatisfied for early recurrence (ER) of hepatocellular carcinoma (HCC) after thermal ablation. We aimed to explore the prognostic value of peripheral immune factors (PIFs) for better ER prediction of HCC after thermal ablation. Patients who received peripheral blood mononuclear cells (PBMCs) tests before thermal ablation were included. Clinical parameters and 18 PIFs were selected to construct ModelClin, ModelPIFs and the hybrid ModelPIFs-Clin. Model performances were evaluated using area under the curve...

The liver is an organ of particular interest for gene therapy, both for correcting inherited metabolic disorders, as well as a biofactory for secretion of therapeutic proteins. The CRISPR/Cas9 genome editing system has greatly improved specificity and precision of gene targeting and can be efficiently delivered to the liver with adeno associated viral vectors (AAV). The goal of this project is to identify novel safe harbor sites in the liver that could drive high expression...

Supplemental Material for Carboxyl-functionalized nanocellulose/sulfonated poly(aryl ether ether ketone ketone) composites for proton exchange membrane by electrospinning by Xiaohui Guo, Xue Yang, Wanli Liu, Shuai Zheng, Yuanrui Wang, Wei Hu, Baijun Liu in High Performance Polymers

A novel nanocomposite proton-exchange membrane (PEM) was obtained by combined electrospinning and solution casting of a composite solution of sulfophenylated poly(ether ether ketone ketone) (SP-PEEKK) and maleic anhydride modified nanocellulose (MN). SP-PEEKK was prepared by polymerization between phenyl hydroquinone and 1,4-bis(4-fluorobenzoyl)benzene followed by post-sulfonation. Nanocellulose (NCC) was prepared by the acid treatment of MCC with sulfuric acid, and MN with carboxyl group was obtained by modifying NCC with maleic anhydride. PEMs with 2% MN (MN2)...

Endothelial function may improve with enhanced external counterpulsation (EECP) or acupuncture. This study aimed to evaluate the feasibility of acupoint stimulation combined with EECP (acupoint-EECP) for endothelial cell function in patients with essential hypertension. Thirty essential hypertensive patients were, randomly divided into two groups, with 15 patients in the acupoint-EECP group, and 15 patients in the control group, of which 3 cases were lost by week 6. Both groups were treated with continued medicine. The...

Electron cyclotron harmonic (ECH) waves, which are responsible for the diffuse aurora, are usually observed with the strongest intensity in the first band. Here, we present observations of enhanced higher-band ECH with wave amplitudes ~1 mV/m by Van Allen Probes. Fully thermal simulation results indicate that these waves can be locally excited by the observed electron distributions, and higher plasma densities and lower magnetic strength are beneficial for exciting the higher-band ECH. The pitch angle...

Wet oxidation absorption is an efficient and promising method of exhaust gas treatment. When the micro-nano bubbles collapse, they can generate hydroxyl radicals with strong oxidising ability, which can oxidise a variety of pollutants in diesel exhaust. Ozone has strong oxidising properties, and the coupling of ozone and micro-nano bubbles can improve the oxidation and removal effects of polluted gases. In this study, the ozone micro-nano bubbles system was used to oxidise NOx, SO2, and...

To screen and identify the antimicrobial ingredients of Forsythia suspensa leaves (FL). A screening method based on a constituent knock-out/knock-in strategy was conducted. The antimicrobial activities of FL components against seven commonly infective strains were determined using the Oxford cup method. Their antimicrobial effects when used in combination with common antibiotics were investigated by a checkerboard titration method. Two of the seven strains, Staphylococcus aureus and methicillin-resistant S. aureus (MRSA), were considered to be the...

An ultracompact fiber inclinometer based on a bubble controlled by Marangoni force was proposed in this Letter. By coupling a 980 nm laser, the bubble could suspend in quantum dots (QDs) liquid-core waveguide (LCW) due to the Marangoni effect. Under the excitation of a 405 nm laser, QDs LCW exhibited green emission centered at 523 nm. When the tilt angle changes, the position of the bubble changes as well, which causes the variation of the...
