A novel convolutional neural network for enhancing the continuity of pavement crack detection.

Pavement cracks affect the structural stability and safety of roads, making accurate identification of crack for assessing the extent of damage and evaluating road health. However, traditional convolutional neural networks often struggle with issues such as missed detection and false detection when extracting cracks. This paper introduces a network called CPCDNet, designed to maintain continuous extraction of pavement cracks.

Augmented-reality-based surgical navigation for endoscope retrograde cholangiopancreatography: A phantom study.

Background: Endoscope retrograde cholangiopancreatography is a standard surgical treatment for gallbladder and pancreatic diseases. However, surgeons is at high risk and require sufficient surgical experience and skills.

Methods: (1) The simultaneous localisation and mapping technique to reconstruct the surgical environment.

City-Wide Traffic Flow Forecasting Using a Deep Convolutional Neural Network.

City-wide traffic flow forecasting is a significant function of the Intelligent Transport System (ITS), which plays an important role in city traffic management and public travel safety. However, this remains a very challenging task that is affected by many complex factors, such as road network distribution and external factors (e.g.

Microbial production of cis-1,2-dihydroxy-cyclohexa-3,5-diene-1-carboxylate by genetically modified Pseudomonas putida.

Arene cis-diols are interesting chemicals because of their chiral structures and great potentials in industrial synthesis of useful chiral chemical products. Pseudomonas putida KT2442 was genetically modified to transform benzoic acid (benzoate) to 1,2-dihydroxy-cyclohexa-3,5-diene-1-carboxylic acid (DHCDC) or named benzoate cis-diol. BenD gene encoding cis-diol dehydrogenase was deleted to generate a mutant named P.

Genetic engineering of Pseudomonas putida KT2442 for biotransformation of aromatic compounds to chiral cis-diols.

Toluene dioxygenase (TDO) catalyzes asymmetric cis-dihydroxylations of aromatic compounds. Pseudomonas putida KT2442 (pSPM01) harboring TDO genes could effectively biotransform a wide-range of aromatic substrates into their cis-diols products. In shake-flask culture, approximately 2.

Microbial transformation of benzene to cis-3,5-cyclohexadien-1,2-diols by recombinant bacteria harboring toluene dioxygenase gene tod.

Toluene dioxygenase (TDO) catalyzes asymmetric cis-dihydroxylation of aromatic compounds. To achieve high efficient biotransformation of benzene to benzene cis-diols, Pseudomonas putida KT2442, Pseudomonas stutzeri 1317, and Aeromonas hydrophila 4AK4 were used as hosts to express TDO gene tod. Plasmid pSPM01, a derivative of broad-host plasmid pBBR1MCS-2 harboring tod from plasmid pKST11, was constructed and introduced into the above three strains.
