Aged nuclear piping has been reported to undergo corrosion-induced accelerated failures, often without giving signatures to current inspection campaigns. Therefore, we need diverse sensors which can cover a wide area in an on-line application. We suggest an integrated approach to monitor the flow accelerated corrosion (FAC) susceptible piping. Since FAC is a combined phenomenon, we need to monitor as many parameters as possible and that cover wide area, since we do not know where the FAC occurs. ...

In a clinical setting, acupuncture treatment consists of multiple components including somatosensory stimulation, treatment context, and attention to needle-based procedures. In order to dissociate somatosensory versus contextual and attentional aspects of acupuncture, we devised a novel form of placebo acupuncture, a visual manipulation dubbed phantom acupuncture, which reproduces the acupuncture needling ritual without somatosensory tactile stimulation. Subjects (N = 20) received both real (REAL) ...

Our study describes the discovery of a series of highly potent hepatitis C virus (HCV) NS5A inhibitors based on symmetrical prolinamide derivatives of benzidine and diaminofluorene. Through modification of benzidine, l-proline, and diaminofluorene derivatives, we developed novel inhibitor structures, which allowed us to establish a library of potent HCV NS5A inhibitors. After optimizing the benzidine prolinamide backbone, we identified inhibitors embedding meta-substituted benzidine core structures ...

A fire detection system requires accurate and fast mechanisms to make the right decision in a fire situation. Since most commercial fire detection systems use a simple sensor, their fire recognition accuracy is deficient because of the limitations of the detection capability of the sensor. Existing proposals, which use rule-based algorithms or image-based machine learning can hardly adapt to the changes in the environment because of their static features. Since the legacy fire detection systems ...

With the difficulty of collecting desirable training data due to the heterogeneities of IoT sensors in various buildings and the scarcity of fire events, it is time consuming and expensive to apply data-driven deep learning approaches to fire detection systems in specific building environments. Simulation-based learning has been actively researched to mitigate data scarcity problems by reproducing potential fire events. Since simulation-based learning mainly depends on synthetic training data, trained ...

The corrosion of nuclear-grade steels in lead–bismuth eutectic (LBE) complicates the realization of high coolant temperatures. Corrosion tests of T91, HT9, and SS316L were performed in static cells at 600 °C for 2000 h at an oxygen level of 10−6 wt.%. The obtained corrosion surfaces of post-processed samples were characterized by several microscopy methods. Up to 1000 h, all the alloys exhibited an evolution of duplex oxide layers, which were spalled until 2000 h due to their increased thickness and ...

One of main operational issues in assembly lines is to assign tasks and workers to workstations so that the maximum productivity can be achieved. Many previous studies have addressed this problem, but most of them have assumed one worker in each workstation or multiple workers with the same skill level in a workstation. In this study, we consider the worker assignment and balancing problem for a real automotive parts assembly line where multiple workers simultaneously perform different tasks in ...

The production of polyhydroxyalkanoates (PHAs) through the biological conversion of methane is a promising solution to address both methane emissions and plastic waste. Type II methanotrophs naturally accumulate a representative PHA, poly(3-hydroxybutyrate) (PHB), using methane as the sole carbon source. In this study, we aimed to produce poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV copolymer) with improved properties compared with PHB, using the type II methanotroph, Methylocystis sp. MJC1. ...

Methylation of cytosines at CpG dinucleotides is essential for mammalian development. MeCP2, MBD1, MBD2, MBD3, and MBD4 comprise a family of proteins that contain a methyl-CpG binding domain (MBD). Except for MBD4, these proteins are involved in gene silencing imposed by methylated DNA. We have identified a human gene that codes for a protein that is 42% identical to MBD3 and 38% identical to MBD2 but lacks the methyl-CpG binding domain. The recombinant protein does not bind to methylated DNA in ...

The amplification and overexpression of Her2 proto‐oncogene have been found to be associated with the development and progression of human breast cancer. A polymorphic valine allele at codon 655 of the Her2 gene ( Her2 V655 ) was suggested by some authors to be a susceptible genetic factor for the development of breast cancer. The Her2 polymorphism at codon 655 was investigated in 304 Korean women including 177 patients with breast cancer. The association between Her2 genotype and Her2 protein overexpression ...

LiBH4–MgH2 composite is one of the most promising solid-state hydrogen storage materials because it exhibits good reversibility as well as lower total reaction enthalpy. Nevertheless, its utilization for onboard hydrogen storage is hindered by poor reaction kinetics. In order to improve the kinetics, pre-milled multi-walled carbon nanotubes (MWCNTs) were added to LiBH4–MgH2 composite. Thereafter, we measured in situ X-ray diffraction patterns of LiBH4–MgH2 and LiBH4–MgH2-MWCNTs composites at various ...

Bump mapping is a technique that represents the detailed parts of an object surface, such as the skin of a peanut, using the geometry mapping without complex modeling. However, the hardware implementation for bump mapping is very expensive, because a large amount of per pixel computations, including the normal vector shading, is required. In this paper, we propose an effective bump mapping algorithm that utilizes the reference space with the polar coordinate system and also propose a new hardware ...
