Effects of astaxanthin on antioxidant capacity of golden pompano (Trachinotus ovatus) in vivo and in vitro

The objective of this research was to study the effect of astaxanthin (AST) on growth performance and antioxidant capacity in golden pompano (Trachinotus ovatus) both in vivo and in vitro. In the in vivo study, two diets were formulated with or without astaxanthin supplementation (D1 and D2; 0 and 200 mg/kg) to feed fish for 6 weeks. In the in vitro study, cells from hepatopancreas ...

Tests of the Stability of Chinese RhFe Resistance Thermometers at Low Temperatures

Rhodium–iron resistance thermometers are recommended as precise thermometers at temperatures below 25 K. The thermometers were developed at the National Physical Laboratory and produced by H. Tinsley and Co Ltd almost 50 years ago. Later, they were made by other companies and institutes as well, but despite this, the availability of the thermometers decreased and a new source of ...

Genetic analysis of RNF213 p.R4810K variant in non-moyamoya intracranial artery stenosis/occlusion disease in a Chinese population

Objectives RNF213 p.R4810K was identified as a susceptibility variant for moyamoya disease in Asia and non-moyamoya intracranial artery stenosis/occlusion disease in Japan and Korea recently. The occurrence of this variant was evaluated in patients with non-moyamoya intracranial artery stenosis/occlusion disease in China. Methods Two study populations were used in this study. One ...

Surface roughness characteristics effects on fluid load capability of tilt pad thrust bearings with water lubrication

The effects of surface roughness characteristics on the fluid load capacity of tilt pad thrust bearings with water lubrication were studied by the average flow model. The flow factors utilized in the average flow model were simulated with various surface roughness parameters including skewness, kurtosis and the roughness directional pattern. The results indicated that the fluid ...

Song Ci (1186–1249), “Father of World Legal Medicine”: History, Science, and Forensic Culture in Contemporary China

Song Ci (1186–1249) was an official of the Southern Song Dynasty best known for authoring the Collected Writings on the Washing Away of Wrongs (Xiyuan jilu), a work often hailed as the world's first systematic treatise on forensic medicine. While biographical details about his life were known in local history writings during the late imperial period, Song had garnered relatively ...

Real-time crash prediction on freeways using data mining and emerging techniques

Recent advances in intelligent transportation system allow traffic safety studies to extend from historic data-based analyses to real-time applications. The study presents a new method to predict crash likelihood with traffic data collected by discrete loop detectors as well as the web-crawl weather data. Matched case–control method and support vector machines (SVMs) technique were ...

Correlated GNSS and temperature measurements at 10-minute intervals on the Severn Suspension Bridge

Global Navigation Satellite System (GNSS) data were gathered on the 998-m-long Severn Suspension Bridge main span. The antennas were located on the tops of the four support towers, as well as five locations on the suspension cables; data were gathered at rates of 10 and 20 Hz. In addition, air and steel temperatures were gathered every 10 min. The GNSS data were processed in an On ...

Many-objective optimization for coordinated operation of integrated electricity and gas network

This paper develops a many-objective optimization model, which contains objectives representing the interests of the electricity and gas networks, as well as the distributed district heating and cooling units, to coordinate the benefits of all parties participated in the integrated energy system (IES). In order to solve the many-objective optimization model efficiently, an improved ...

Effect of Fe3O4 nanoparticles on Sphingobium yanoikuyae XLDN2-5 cells in carbazole biodegradation

This study explored the effect of Fe3O4 nanoparticles on Sphingobium yanoikuyae XLDN2-5, an important environmentally microorganism in carbazole biodegradation process. Microbial cell/Fe3O4 nanoparticles biocomposite was constructed by assembling Fe3O4 nanoparticles onto the surface of Sphingobium yanoikuyae XLDN2-5 cells. With the increase in Fe3O4 nanoparticles concentration, ...

Starvation signals in yeast are integrated to coordinate metabolic reprogramming and stress response to ensure longevity

Studies on replicative and chronological aging in Saccharomyces cerevisiae have greatly advanced our understanding of how longevity is regulated in all eukaryotes. Chronological lifespan (CLS) of yeast is defined as the age-dependent viability of non-dividing cell populations. A number of nutrient sensing and signal transduction pathways (mainly TOR and PKA) have been shown to ...

Simple solution to the optimal deployment of cooperative nodes in two-dimensional TOA-based and AOA-based localization system

Cellular-based cooperative communication is a promising technique that allows cooperation among mobile devices not only to increase data throughput but also to improve localization services. For a certain number of cooperative nodes, the geometry plays a significant role in enhancing the accuracy of target. In this paper, a simple solution to the deployment of cooperative nodes ...

Risk assessment of precipitation extremes in northern Xinjiang, China

This study was conducted using daily precipitation records gathered at 37 meteorological stations in northern Xinjiang, China, from 1961 to 2010. We used the extreme value theory model, generalized extreme value (GEV) and generalized Pareto distribution (GPD), statistical distribution function to fit outputs of precipitation extremes with different return periods to estimate risks ...

Aberrant DNA methylation and expression of SPDEF and FOXA2 in airway epithelium of patients with COPD

Background Goblet cell metaplasia, a common feature of chronic obstructive pulmonary disease (COPD), is associated with mucus hypersecretion which contributes to the morbidity and mortality among patients. Transcription factors SAM-pointed domain-containing Ets-like factor (SPDEF) and forkhead box protein A2 (FOXA2) regulate goblet cell differentiation. This study aimed to (1) ...

Performance of Horizontal Wells with Inflow Control Devices in Homogeneous Reservoirs with Bottom Water Drive

Horizontal well techniques play an important role in the development of unconventional oil and gas plays. A key challenge in horizontal well completions is that water cut will rise rapidly once water breakthrough without inflow control. Inflow control devices restrict flow by creating an additional drop in pressure to equal the drop in wellbore pressure in order to reduce water or ...

Mutual Information-Based Tracking for Multiple Cameras and Multiple Planes

Based on mutual information (MI), this paper proposes a systematic analysis of tracking a multi-plane object with multiple cameras. Firstly, a geometric model consisting of a piecewise planar object and multiple cameras is setup. Given an initial pose guess, the method seeks a pose update that maximizes the global MI of all the pairs of reference image and camera image. An object ...
