Every Cloud has a Silver Lining: Using Silver Concentration to Identify the Number of Sources of Lead used in Shang Dynasty Bronzes

Ruiliang LIU, A. Mark POLLARD, Cheng LIU, Jessica RAWSON

Acta Geologica Sinica ‐ English Edition > 94 > 3 > 585 - 593

The use of lead, some of which is characterized by a highly radiogenic signature, sharply distinguishes Bronze Age China from the rest of Eurasia. Scholars have long hypothesized that silver can offer an independent proxy to characterize lead minerals. The summary of silver distribution associated with Shang and Western Zhou bronzes in this paper reveals an important difference between the south (Sanxingdui,...

Crosstalk between tubular epithelial cells and glomerular endothelial cells in diabetic kidney disease

Si‐Jie Chen, Lin‐Li Lv, Bi‐Cheng Liu, Ri‐Ning Tang

Cell Proliferation > 53 > 3 > n/a - n/a

In recent years, although the development of clinical therapy for diabetic kidney disease (DKD) has made great progress, the progression of DKD still cannot be controlled. Therefore, further study of the pathogenesis of DKD and improvements in DKD treatment are crucial for prognosis. Traditional studies have shown that podocyte injury plays an important role in this process. Recently, it has been...

Tunable Structural Color Patterns Based on the Visible‐Light‐Responsive Dynamic Diselenide Metathesis

Cheng Liu, Zhiyuan Fan, Yizheng Tan, Fuqiang Fan, more

Advanced Materials > 32 > 12 > n/a - n/a

Structural color materials with reversible stimuli‐responsiveness to external environment have been widely used in sensors, encryption, display, and other fields. Compared with other stimuli, visible light is highly controllable both temporally and spatially with less damage to materials, which is more suitable for structural color patterning. Herein, a new diselenide‐containing shape memory material...

Tighter Bound of Entropic Uncertainty under the Unruh Effect

Juan He, Zhi Yong Ding, Jia Dong Shi, Cheng Cheng Liu, more

Annalen der Physik > 532 > 3 > n/a - n/a

The uncertainty principle limits the ability to simultaneously predict measurement outcomes for two non‐commuting observables of a quantum particle. However, the uncertainty can be violated by considering a particle as a quantum memory correlated with the primary particle. By modeling an Unruh–Dewitt detector coupled to a massless scalar field, it is explored how the Unruh effect affects the entropic...

The association of the optimal bolus of dexmedetomidine with its favourable haemodynamic outcomes in adult surgical patients under general anaesthesia

Cheng‐yu Wang, Fang Chen, Junzheng Wu, Shu‐ying Fu, more

British Journal of Clinical Pharmacology > 86 > 1 > 85 - 92

Aims Dexmedetomidine is highly specific α2‐adrenoceptor agonist. A single bolus of dexmedetomidine can achieve clinical therapeutic effect. Therefore, it is essential to know the safety margin between the clinical effectiveness dosages of dexmedetomidine and its side effect. Methods A total of 42 patients who underwent elective thyroidectomy were enrolled in this study. Dexmedetomidine was given...

Enhanced properties of phthalonitrile resins under lower curing temperature via complex curing agent

Zhihuan Weng, Yue Hu, Yu Qi, Shouhai Zhang, more

Polymers for Advanced Technologies > 31 > 2 > 233 - 239

High curing temperature has been restricting the application and development of phthalonitrile resin. A complex curing agent containing melamine (ME) and ZnCl₂ was developed to promote the curing reaction of resorcinol‐based phthalonitrile resin (DPPH). The thermal stability of ME can be significantly enhanced via adding ZnCl₂, which was due to the interaction between ZnCl₂ and amino group in ME....

Journal of Cardiac Surgery > 34 > 12 > 1540 - 1549

Background Primary malignant cardiac tumors (PMCTs) are fatal, but up to now, there is still a lack of survival prediction model for prognosis evaluation. We developed nomograms to predict overall survival (OS) and cancer‐specific survival (CSS) for PMCTs by the Surveillance, Epidemiology, and End Result (SEER) database. Methods A total of 506 PMCTs participants were identified in the SEER database...

Effects of water intake layout along the wharf shoreline on ships

Xian-wei Kong, Lei Ding, Hai-cheng Liu, Jing Qu, more

Polish Maritime Research > 2019 > nr 4 > 165--171

The construction of a water intake along the wharf shoreline can realise the intensive and comprehensive utilisation of the shoreline. However, since the water intake will increase the lateral flow at the wharf and also the hydrodynamic forces on ships, it will bring risks to ships mooring and leaving. The effects of the water intake on ships are studied using a physical model, numerical model and...

Introduction the revolving scarf osteotomy for treating severe hallux valgus with an increased distal metatarsal articular angle: a retrospective cohort study

Xinwen Wang, Qian Wen, Yi Li, Cheng Liu, more

BMC Musculoskeletal Disorders > 2019 > 20 > 1 > 1-7

Background Hallux valgus(HV) with an increased distal metatarsal articular angle (DMAA) is one of the most common foot deformities among adults. Double metatarsal osteotomy (DMO) is effective in treating severe HV deformity with an increased DMAA. However, this technique presents the risk of avascular necrosis (AVN) of the metatarsal head and transfer metatarsalgia due to shortening of the first metatarsal...
