Socioeconomic and demographic characterization of an endemic malaria region in Brazil by multiple correspondence analysis

Background In the process of geographical retraction of malaria, some important endemicity pockets remain. Here, we report results from a study developed to obtain detailed community data from an important malaria hotspot in Latin America (Alto Juruá, Acre, Brazil), to investigate the association of ...

Detection of pelagic habitat hotspots for skipjack tuna in the Gulf of Bone-Flores Sea, southwestern Coral Triangle tuna, Indonesia

Using remote sensing of sea surface temperature (SST), sea surface height anomaly (SSHA) and chlorophyll-a (Chl-a) together with catch data, we investigated the detection and persistence of important pelagic habitat hotspots for skipjack tuna in the Gulf of Bone-Flores Sea, Indonesia. We analyzed the ...

Data reconstruction can improve abundance index estimation: An example using Taiwanese longline data for Pacific bluefin tuna

Catch-per-unit-effort (CPUE) is often the main piece of information used in fisheries stock assessment; however, the catch and effort data that are traditionally compiled from commercial logbooks can be incomplete or unreliable due to many reasons. Pacific bluefin tuna (PBF) is a seasonal target species ...

Advances in the analysis of complex food matrices: Species identification in surimi-based products using Next Generation Sequencing technologies

The Next Generation Sequencing (NGS) technologies represent a turning point in the food inspection field, particularly for species identification in matrices composed of a blend of two or more species. In this study NGS technologies were applied by testing the usefulness of the Ion Torrent Personal ...

A graph localization approach to assist a diver-in-distress

In this paper, we focus on the problem of locating a diver-in-distress using graph localization tools. Without GPS reception while being submerged, a diver cannot report on his location and upon distress can only rely on help from fellow divers by sending periodic SOS messages using underwater acoustic ...

Multi-Elements in Source Water (Drinking and Surface Water) within Five Cities from the Semi-Arid and Arid Region, NW China: Occurrence, Spatial Distribution and Risk Ass...

The purpose of this study was to identify the concentration of multi-elements (MEs) in source water (surface and drinking water) and assess their quality for sustainability. A total of 161 water samples including 88 tap drinking waters (DW) and 73 surface waters (SW) were collected from five cities ...

Research on fault warning of AC filter in converter station based on RBF neural network

AC filter in converter station is an important part of HVDC transmission system, and the tripping accident of AC filter will directly affect the transmission power of the DC transmission system. This paper presents a method for on-line identification of AC filter's health status based on the opening/closing ...

Deriving sea surface wind from synthetic aperture radar based on Fourier transform and neural network

The acquisition of sea surface wind information is of great value for marine activities, such as navigation, fishing and sea operations. In this paper, the ERS-2 SAR data, covering the Yangtze River estuary and its adjacent waters at around 10:30 local time on March 15, 2007, was applied to retrieve ...

Developing integrated classification system to provide systematic information of science and technology policy

To support evidence-based science and technology policy, it is important to provide information systematically through platforms such as a decision support system. This study suggests an integrated classification system for categorizing information as a way to provide it systematically. The integrated ...

Subsea Cable Health Monitoring System

Subsea power cables forms a major part of tidal energy systems and are damaged easily due to drag of the ship anchors and fishing trolls. This paper addresses both structural health of subsea cable as well as a multi-sensor monitoring techniques for a robust defect detection system. The paper addresses ...

Application of synergetic and fractal methods in the implementation of the environmental audit system

The decline of the environmental situation in the world generates a need for regular drinking water quality monitoring as well as for the efficient nature management system development. An introduction to the concept of a fractal-synergetic approach to the procedure for conducting the environmental ...

Data-driven SISO predictive control using adaptive discrete-time fliess operator approximations

Modern control theory has been applied successfully in a wide variety of engineering disciplines for decades. In sharp contrast to this situation, however, there are fields like ecology where control methodologies have not been so successful in practice. This largely due to the poor quality of models ...

Design and Deployment of a Wireless Sensor Network for the Mar Menor Coastal Observation System

The Coastal Ocean Observation System of Murcia Region (OOCMUR) was established in 2008 as a major scientific and technological infrastructure in Spain with the main objective of studying the impact of global climate change in the Mediterranean. The coastal lagoon of Mar Menor in southeast Spain was ...

A PSO fuzzy-expert system: As an assistant for specifying the acceptance by NOET measures, at PH.D level

The intelligent decision making systems are useful tools for the assistance of human expert, and or as a perfect alternative for expert in a variety of auto-decision making fields. The use of such systems in education, agriculture, industry, fishery, animal husbandry etc., can decrease manpower errors ...

Deep Census: AUV-Based Scallop Population Monitoring

We describe an integrated system for vision-based counting of wild scallops in order to measure population health, particularly pre- and post-dredging in fisheries areas. Sequential images collected by an autonomous underwater vehicle (AUV) are independently analyzed by a convolutional neural network ...

HSF4 regulates lens fiber cell differentiation by activating p53 and its downstream regulators

Cataract refers to opacities of the lens that impede the passage of light. Mutations in heat shock transcription factor 4 (HSF4) have been associated with cataract; however, the mechanisms regarding how mutations in HSF4 cause cataract are still obscure. In this study, we generated an hsf4 knockout ...

Activation of the Nkx2.5–Calr–p53 signaling pathway by hyperglycemia induces cardiac remodeling and dysfunction in adult zebrafish

ABSTRACT Hyperglycemia is an independent risk factor for diabetic cardiomyopathy in humans; however, the underlying mechanisms have not been thoroughly elucidated. Zebrafish (Danio rerio) was used in this study as a novel vertebrate model to explore the signaling pathways of human adult cardiomyopathy. ...

Joint Toxicity of Different Heavy Metal Mixtures after a Short-Term Oral Repeated-Administration in Rats

The systemic toxicity of different combinations of heavy metal mixtures (HMMs) was studied according to equivalent proportions of the eight most common detectable heavy metals found in fish consumption in the Ningbo area of China. The ion mass proportions of Zn, Cu, Mn, Cr, Ni, Cd, Pb, and Hg were 1070.0, ...

Maternal prenatal blood mercury is not adversely associated with offspring IQ at 8 years provided the mother eats fish: A British prebirth cohort study

Background Conflicting evidence concerning possible harm from mercury (Hg) in regard to offspring cognition if the woman eats fish has prompted this study to examine evidence from a British pre-birth cohort to investigate the relationship between the two. Methods Pregnant women (median prenatal blood ...

An always best connected-supported intelligent handover decision mechanism based on improved artificial fish swarm algorithm

In order to cope with the rapid development of the Internet and to solve the lack of IP address resources, this paper proposes an ABC(Always Best Connected)-supported intelligent handover decision mechanism based on Improved Artificial Fish Swarm Algorithm (IAFSA). The proposed mechanism takes into ...
