Laser cutting is a non-contact thermal cutting process and an integral part of manufacturing. In metal processing, laser cutting is at the forefront of the manufacturing chain followed by joining and manufacturing processes like welding. The future of metal manufacturing processes like laser cutting shall rely on intelligent systems such as automation and robotics based on the advancement of technology and digital transformation spearheaded by Industry 4.0. Moreover, the digital transition where robots and automated systems are key drivers creates a broader platform to utilize energy-efficiency materials. Such energy-efficient materials include high-strength steels (HSS) for structural applications (e.g. bio-energy structures, wind turbines, ice-going vessels) onshore, offshore and in the Arctic region. The aim of this paper is to elucidate the prospects of robot laser cutting systems in the framework of integrated metal manufacturing in future factories. Previous studies on laser cutting technologies are examined based on scientific and industrial perspectives. Robot laser cutting system is compared with the well-known flat-bed laser cutting CNC machine in several aspects including flexibility in manufacturing, ease for digitalization, off-line capabilities and investment analysis. The findings shall help to determine the competitiveness of robot laser cutting systems with flat-bed laser cutting CNC machines, especially when considering metal manufacturing in small and medium-sized enterprises (SMEs). The outcome of this study is to stir up experimental and computational research on robot laser cutting systems of metals, and help companies in their decision-making process when deciding which laser cutting system will best suit their manufacturing operations in the future.

New Levels in ^118Pd Observed in the β Decay of Very Neutron-Rich ^118Rh Isotope

Chinese Physics Letters 2006年第4期23卷 808-811页

作者：王友宝 P. Dendooven J. Huikari A. Jokinen V. S. Kolhinen G. Lhersonneau A. Nieminen S. Nummela H. Penttila K. Perajarvi S. Rinta-antila J. Szerypo J. C. Wang J.Aysto China Institute of Atomic Energy PO Box 275(46) Beijing 102413 Department of Physics PO Box 35(YFL) FIN-40014 University of Jyvaskyla Finland

We investigate the β decay of very neutron-rich ^118Rh isotope using on-line mass-separated sources which are produced by applying 25 MeV proton induced symmetric fission of natural uranium at the IGISOL facility. The β-γ and γ-γ coincidence spectroscopy is employed to establish the level scheme of daughter nucleus ^118Pd. Five low-lying new levels are identified for the first time with tentative spin and parity assignments based on the even-mass Pd systematics.

Objective. Preoperative differentiation of primary andmetastatic ovarian tumors is difficult. Young age of the patient,bilateralism and reduced multilocularity are cited characteristics of secondary ovarian malignancies. We sought to identity pre- and perioperative factors which may aid in differentiating metastatic ovarian tumors from primary ovarian *** and methods. We performed a retrospective analysis of demographic parameters, preoperative serum tumor marker levels and ultrasonographic as well as operative findings in 38 patients with secondary ovarian malignancies and 76 control patients with primary epithelial ovarian cancer. All patients were treated at our institute from 1996 to 2003. Results. The proportion of secondary ovarian tumors, of all ovarian malignancies,was 5.2% . The most common sites of origin were the gastrointestinal tract (42% ), breast (29% ) and peritoneum(16% ). Fifty- eight percent of the patients with a secondary ovarian tumor had a history of previous malignancy; 42% of the primary malignancies were detected only following diagnosis of ovarian metastasis. The two patient groups (primary or secondary ovarian malignancy) could not be distinguished by age, parity, menopausal status or history of *** the serum markers, the preoperative level of serum CA 125 was not different between the two groups. Both serum tumor associated trypsin inhibitor (TATI) (7.2 ± 9.6 vs. 4.7 ± 9.4μ g/l [mean ± SD]) and carsino embryonic antigen (CEA) levels(19.7± 30.8 vs. 6.7 ± 120.0 μ g/l) were higher in the group with secondary malignancies (P < 0.02). The metastatic ovarian tumors, as measured preoperatively by ultrasonography (US),were smaller (64 mm, 62- 89 mm [median, 95% Cl]) than the primary tumors (105 mm, 104- 134 mm) (P < 0.0005). The same was true for tumor sizes measured at surgery (P < 0.05)- . Furthermore, the secondary tumors were more often solid(50 vs. 10% ) (P < 0.005), and more seldom cystic- solid (17 vs. 55% )
