stable two-sided matching of slot allocation in airport collaborative decision making by top trading cycles mechanism

引用

Chinese Journal of Aeronautics 2018年第3期31卷 534-545页

作者： Marcio Augusto da silva souza Weigang LI Reinaldo Crispiniano GARCIA Trans Lab Department of Computer Science University of Brasilia Department of Production Engineering University of Brasilia

The problem of capacity shortage in some airports needs to be dealt with sustainable solutions including a more efficient use of the existing runway slots at the airports. The Collaborative Decision Making（CDM） is an important approach applied to Air Traffic Management（ATM）to achieve this efficient use of the slots allocation. Using the Matching approach for two-sided markets of Game theory, the Top Trading Cycle CDM（TTC-CDM） algorithm developed in this research is an extension of the CDM approach aggregating the Ground Delay Program（GDP）of the air sector. The paper compared the developed TTC-CDM model to the existing models such as the conventional Compression algorithm in CDM, the Trade Cycle algorithm and the Deferred Acceptance CDM（da-CDM） model to evaluate the performance of the proposed model. Through a case study, the results show the effective application of TTC-CDM model to slot allocation in ATM and also presents the advantage of considering the preferences of airport managers beside ATC controllers and airlines in the decision processing.

The corpus cavernosum after treatment with dutasteride or finasteride： a histomorphometric study in a benign prostatic hyperplasia rodent model

引用

Asian Journal of Andrology 2018年第5期20卷 505-510页

作者： Marcello H A da silva Waldemar s Costa Francisco J B sampaio Diogo B De souza Urogenital Research Unit Rio de Janeiro State University Rio de Janeiro RJ 20551-030 Brazil

Erectile dysfunction is a common side effect of finasteride and dutasteride treatments. The objective of this study was to investigate the structural changes in the penis using a benign prostatic hyperplasia （BPH） rodent model treated with dutasteride or finasteride. sixty male rats were divided into the following groups： C, untreated control rats; C ＋ D, control rats receiving dutasteride; C ＋ F, control rats receiving finasteride; H, untreated spontaneously hypertensive rats （sHRs）; H ＋ D, sHRs treated with dutasteride; and H ＋ F, sHRs treated with finasteride. Treatments were performed for 40 days, and penises were collected immediately thereafter. The organs were analyzed using histomorphometric methods to determine the cross-sectional penile area, as well as the surface density （sv） of smooth muscle fibers, connective tissue, elastic system fibers, and sinusoidal spaces of the corpus cavernosum. The results were compared using a one-way ANOVA with Bonferroni＇s posttest. Groups C ＋ D and C ＋ F had a significantly smaller penile cross-sectional area, but more elastic system fiber sv compared to Group C. Group C ＋ D showed less smooth muscle sv, and Group H showed more connective tissue but a smaller sinusoidal space sv in the corpus cavernosum compared to Group C. Groups H ＋ D and H ＋ F had less smooth muscle sv than Group H. Group H ＋ D also had more connective tissue and elastic system fiber sv than Group H. Both dutasteride and finasteride promoted penile modifications in the control rat penis, although this affect was ~reater in Group H animals. In this rodent model, dutasteride was the drug that most affected the corpus cavernosum.

Fractionation of rare earth and other trace elements in crabs,Ucides cordatus,from a subtropical mangrove affected by fertilizer industry

Fractionation of rare earth elements（REE） and other trace metal concentrations（Th, U, Cd,Cr, Cu, Ni, Pb, and Zn） between mangrove sediments and claw muscles and shells of male crabs（Ucides cordatus） from a subtropical estuary highly impacted by fertilizer industry activities was investigated. This is the first record of REE distribution in these organisms,and the results showed higher accumulations of these metals, U and Th in shells, probably related to the replacement of Ca during molting. Contents of Cd, Cr and Ni were similar in both tissues, but Cu, Zn and Pb were mostly accumulated in the claw muscle with concentrations above those considered safe for human consumption according to the Brazilian legislation. REE fractionation was different in the analyzed tissues being softer in the shells. The results provided evidences that the water absorbed during molting controls the chemistry of REE in shells. In contrast, the chemistry of REE in the claw muscle, in which was observed preferential absorption of light REE, is controlled by diet. REE fractionation obtained for the claw muscles was closely correlated to the observed in the contaminated substrate and in materials related to the production of phosphate fertilizers（contamination source）, which supports their transference to this Ucides cordatus tissue without fractionation by the ingestion of sediments. Our results showed the potential use of crab tissues for monitoring REE and trace element sources in mangrove areas, with claw muscle exhibiting the contaminant source fingerprint.
