Mean Li–Yorke chaos along some good sequences

If a topological dynamical system (X, T) has positive topological entropy, then it is multivariant mean Li–Yorke chaotic along a sequence \(\{a_k\}_{k=1}^\infty \) of positive integers which is “good” for pointwise ergodic convergence with a mild condition; more specifically, there exists a Cantor subset K of X such that for every \(n\ge 2\) and pairwise distinct points ...

Characterization and Processing of Advanced Porous Materials

significantly improved by loading with a small amount of metallic iron nanoparticles. Bowen Li and Jian Li are the JOM advisors for the Materials Characterization Committee of the TMS Extraction & Processing

Carbon Nanodots as Dual-Mode Nanosensors for Selective Detection of Hydrogen Peroxide

Hydrogen peroxide (H2O2) is an important product of oxidase-based enzymatic reactions, such as glucose/glucose oxidase (GOD) reaction. Therefore, the probing of generated H2O2 for achieving the detection of various carbohydrates and their oxidases is very significative. Herein, we report one kind of dual-emission carbon nanodots (CDs) that can serve as novel dual-mode nanosensors ...

Transcriptomic variation of eyestalk reveals the genes and biological processes associated with molting in Portunus trituberculatus

Background Molting is an essential biological process throughout the life history of crustaceans, which is regulated by many neuropeptide hormones expressed in the eyestalk. To better understand the molting mechanism in Portunus trituberculatus, we used digital gene expression (DGE) to analyze single eyestalk samples during the molting cycle by high-throughput sequencing. Results ...

A Comparative Study of Video-Assisted Thoracic Surgery with Thoracotomy for Middle Lobe Syndrome

right middle lobe or left lingular segment was defined as MLS Jian Li and Chengwu Liu have contributed equally to this study. [2]. Most patients with MLS would recover by applying antibiotics and

The coherent large-scale circulation change between dry/wet years over central eastern China simulated by NCAR CAM5

This study evaluates the simulation of the coherent circulation structure correspond to the changes of mid-summer (July–August) rainfall over eastern China (30°–40° N, 110°–120° E) in high-resolution NCAR CAM5. Forced by historical sea surface temperatures (SSTs), the NCAR CAM5 reasonably reproduces coherent changes of temperature and large-scale circulations, corresponding to the ...

Impact of moisture divergence on systematic errors in precipitation around the Tibetan Plateau in a general circulation model

Current state-of-the-art atmospheric general circulation models tend to strongly overestimate the amount of precipitation around steep mountains, which constitutes a stubborn systematic error that causes the climate drift and hinders the model performance. In this study, two contrasting model tests are performed to investigate the sensitivity of precipitation around steep slopes. ...

Size effect of Au/PAMAM contrast agent on CT imaging of reticuloendothelial system and tumor tissue

Polyamidoamine (PAMAM)-entrapped Au nanoparticles were synthesized with distinct sizes to figure out the size effect of Au-based contrast agent on CT imaging of passively targeted tissues. Au/PAMAM nanoparticles were first synthesized with narrow distribution of particles size of 22.2 ± 3.1, 54.2 ± 3.7, and 104.9 ± 4.7 nm in diameters. Size effect leads no significant difference on ...

The patterns and timing of recurrence after curative resection for gastric cancer in China

Background The recurrence of gastric cancer after curative resection had adverse effects on patients’ survival. The treatment presence varied from different countries. The aims of this study were to understand the recurrence incidence, patterns, and timing and to explore the risk factors in China. Methods One thousand three hundred four patients who undergoing curative resection ...

New classification of lunate fossa fractures of the distal radius

Background A die-punch fracture is a depression fracture of the lunate fossa of the distal radius. We propose a morphological classification of die-punch fractures that includes five types: center depression fractures, vertical depression fractures, volar depression fractures, dorsal depression fractures, and double die-punch fractures. Methods The radiographs of 112 die-punch ...

A microRNA molecular modeling extension for prediction of colorectal cancer treatment

Background Several studies show that the regulatory impact of microRNAs (miRNAs) is an essential contribution to the pathogenesis of colorectal cancer (CRC). The expression levels of diverse miRNAs are associated with specific clinical diagnoses and prognoses of CRC. However, this association reveals very little actionable information with regard to how or whether to treat a CRC ...

CD147 promotes cell motility via upregulation of p190-B RhoGAP in hepatocellular carcinoma

Background The acquisition of inappropriate migratory feature is crucial for tumor metastasis. Rho-family GTPases including RhoA are molecular switches that play critical roles in regulating cell movement. We investigated the molecular mechanism underlying CD147 induced RhoA deactivation in hepatocellular carcinoma (HCC) cells. Methods Wound-healing assay was performed to study the ...

Monitoring the Prevalence of Leucocytozoon sabrazesi in Southern China and Testing Tricyclic Compounds against Gametocytes

Leucocytozoon parasites infect many species of avian hosts, including domestic chicken, and can inflict heavy economic loss on the poultry industry. Two major species of Leucocytozoon parasites have been reported in China, L. sabrazesi and L. caulleryi, although L. sabrazesi appears to be more widespread than L. caulleryi in southern China. The traditional method for detecting ...

Effort-reward imbalance and perceived quality of patient care: a cross-sectional study among physicians in Germany

Background Work stress may impair physicians’ ability to provide high quality patient care. Prior research remains however sparse and has insufficiently explored explanations for this relationship. It has been suggested that physicians’ poor mental health is one potential explanatory factor. We drew on a well-established model to measure work stress (the effort-reward imbalance ...
