Will the Order Be Canceled? Order Cancellation Probability Prediction Based on Deep Residual Model

Haokai Sun, Zhiqiang Lv, Jianbo Li, Zhihao Xu & Zhaoyu Sheng
Online ride-hailing is gradually becoming one of the indispensable travel modes for people. Online ride-hailing platforms receive tens of thousands of taxi travel orders every day. However, some orders are canceled by the user after the driver answers. User cancellation of orders will disrupt the regular operation of the taxi platform, reduce the efficiency and income of drivers on the online ride-hailing platform, and affect the ride experience of other users. To capture the relationship...

Baoyi Huang, Mingli Huang, Chengfeng Zhang, Zhiyin Yu, Yawen Hou, Yun Miao & Zheng Chen
Abstract Background Predicting allograft survival is vital for efficient transplant success. With dynamic changes in patient conditions, clinical indicators may change longitudinally, and doctors’ judgments may be highly variable. It is necessary to establish a dynamic model to precisely predict the individual risk/survival of new allografts. Methods The follow-up data of 407 patients were obtained from a renal allograft failure study. We introduced a landmarking-based dynamic Cox model that incorporated baseline values (age at transplantation,...

Emergency versus delayed hepatectomy following transarterial embolization in spontaneously ruptured hepatocellular carcinoma survivors: a systematic review and meta-analysis

Wei Zhang, Zhangkan Huang & Xu Che
Abstract Background Spontaneous rupture is a life-threatening complication of hepatocellular carcinoma (HCC). Recent trends in surgical treatments avoid emergency hepatectomy (EH) and favor emergency transarterial embolization (TAE) followed by delayed hepatectomy (DH). Still, there is debate on which is the better treatment option and whether delaying hepatectomy increases peritoneal metastasis. Aim To provide evidence-based references for the optimal management of patients with spontaneously ruptured HCC by comparing the outcomes of EH and DH. Methods Literature...

Vari-focal liquid microlens array using electrically responsive fluid actuated by ring array patterned electrode

Miao Xu, Yating Liu, Senhao Li, Jing Li, Lyudi Zhang & Hongbo Lu
A transparent fluid dibutyl adipate (DBA) is suitable for fabricating the adaptive lens due to its unique deformation under a direct current (DC) electric field. In this report, a DBA liquid microlens array (LMA) with tunable focal length is demonstrated. A hydrophobic layer deposited in the ring-array patterns on the electrode induced the formation of the DBA liquid microdroplets array self-assembly. The electronegative DBA liquid tends to move to the anode at a DC voltage....

A novel serum spherical lectin from lamprey reveals a more efficient mechanism of immune initiation and regulation in jawless vertebrates

Jiali Lu, Jinsong Duan, Yinglun Han, Meng Gou, Jun Li, Qingwei Li & Yue Pang
Abstract The innate immune system is the body’s first line of defense against pathogens and involves antibody and complement system-mediated antigen removal. Immune-response-related complement molecules have been identified in lamprey, and the occurrence of innate immune response via the mannose-binding lectin-associated serine proteases of the lectin cascade has been reported. We have previously shown that lamprey (Lampetra japonica) serum can efficiently and specifically eliminate foreign pathogens. Therefore, we aimed to understand the immune mechanism of...

Accurate Determination of Trace Cadmium in Soil Samples with Graphite Furnace Atomic Absorption Spectrometry Using Metal–Organic Frameworks as Matrix Modifiers

Hanyi Liu, Hao Cui, Yu Wang, Zhenmao Jiang, Lidan Lei & Shiqiang Wei
Cadmium (Cd) is a highly toxic heavy metal that is widely distributed in soils at low concentrations. Its volatilization loss occurs at an ashing temperature higher than 350 °C. Accordingly, the accurate determination of its concentration in soils often requires the addition of chemical modifiers by graphite furnace atomic absorption spectrometry (GFAAS) to improve the thermal stability of Cd. In this work, a metal–organic framework (MOF, UIO-66-NH2) was utilized as a matrix modifier to improve...

Weizhu Zeng, Xiaoyu Shan, Li Liu & Jingwen Zhou
Abstract 1,3-Dihydroxyacetone (DHA) is a commercially important chemical and widely used in cosmetics, pharmaceuticals, and food industries as it prevents excessive water evaporation, and provides anti-ultraviolet radiation protection and antioxidant activity. Currently, the industrial production of DHA is based on a biotechnological synthetic route using Gluconobacter oxydans. However, achieving higher production requires more improvements in the synthetic process. In this study, we compared DHA synthesis levels in five industrial wild-type Gluconobacter strains, after which the...
