Multi-Objective Ant Colony Algorithm in EPC Risk Control

AbstractAccording to the risks and risk control target in energy performance contracting (EPC), this paper has designed the risk control measure set. On the basis, a risk control model is put forward, including the risk evaluation, risk control cost, risk loss. Then, a multi-objective ant colony algorithm, based on Pareto theory, is used to solve the model. A series of Pareto optimal solutions are got by example. The result shows that the solutions have the better diversity and convergence. At the same time, the model can find the best combination of various risk control measures in EPC, which can provide direct evidence for the company of EPC

Clinical efficacy of radiotherapy combined with sodium glycididazole in the treatment of recurrent oesophageal carcinoma

Purpose: To assess the clinical efficacy and side effects of radiotherapy combined with sodium glycididazole in the treatment of recurrent esophageal carcinoma.Methods: Ninety patients with locally recurrent oesophageal carcinoma who were admitted to the Oncology Department at Taian City Central Hospital, Shandong, China, were randomly divided into a treatment group (treated with radiotherapy and sodium glycididazole) and a control group (treated with radiotherapy alone) in a randomized study. Short-term curative effects, median progression-free survival (PFS), and side effects were compared between the two groups.Results: The cure rate in the treatment group was 86.70 %, whereas that in the control group was 51.10 % (p < 0.05). Median PFS in the treatment group was 9.9 months versus 5.3 months in the control group (p < 0.05). Side effects in both groups included alopecia, headache, nausea, vomiting and leucopaenia, at level one or two. In this regard, the difference between the two groups was statistically insignificant (p > 0.05).Conclusion: Radiotherapy combined with sodium glycididazole shows a higher short-term curative effect in the treatment of recurrent oesophageal carcinoma than radiotherapy alone.Keywords: Alopecia, Leucopaenia, Oesophageal carcinoma, Radiotherapy, Sodium glycididazol

Constraints on flavor-changing neutral-current HtqHtq couplings from the signal of tHtH associated production with QCD next-to-leading order accuracy at the LHC

We study a generic Higgs boson and a top quark associated production via model-independent flavor-changing neutral-current couplings at the LHC, including complete QCD next-to-leading order (NLO) corrections to the production and decay of the top quark and the Higgs boson. We find that QCD NLO corrections can increase the total production cross sections by about 48.9% and 57.9% for the $Htu$ and $Htc$ coupling induced processes at the LHC, respectively. After kinematic cuts are imposed on the decay products of the top quark and the Higgs boson, the QCD NLO corrections are reduced to 11% for the $Htu$ coupling induced process and almost vanish for the $Htc$ coupling induced process. Moreover, QCD NLO corrections reduce the dependence of the total cross sections on the renormalization and factorization scales. We also discuss signals of the $tH$ associated production with the decay mode t \rightarrow bl^{+}E \slash_{T}, H \rightarrow b\bar{b} and $t\bar{t}$ production with the decay mode \bar{t} \rightarrow H\bar{q}, t\rightarrow bl^{+}E \slash_{T}. Our results show that, in some parameter regions, the LHC may observe the above signals at the $5\sigma$ level. Otherwise, the upper limits on the FCNC $Htq$ couplings can be set.Comment: 28 pages, 14 figures, 5 tables; version published in PR

1,2-Bis(4-nitro­benz­yl)diselane

The title compound, C14H12N2O4Se2, is not chiral, but the mol­ecules assume a chiral conformation in the solid state and crystallize as an aggregate. The central C—Se—Se—C torsion angle is 90.4 (2)°, while the two Se—Se—C—C fragments assume gauche conformations with values of −59.4 (5) and 67.5 (4)°. The dihedral angle between the two benzene rings is 80.74 (14)°
