进食障碍是一种严重的精神疾病,近年来在全球的发病率迅速上升。进食障碍经常与其他精神疾病并存,且死亡率较高。英国伦敦大学Llewellyn教授领衔的团队使用了荷兰R世代研究(Generation R study)和英国Gemini研究的数据,对2801名荷兰儿童和869名英国儿童开展了为期10年的随访研究。儿童4~5岁时,父母报告儿童食欲特征;12~14岁时,青少年自我报告暴饮暴食和限制性进食等多种进食障碍症状。结果显示,童年早期对食物反应性较高(看到、闻到或尝到美味食物时有进食的冲动)会增加青少年期出现暴饮暴食、失控性进食(感到失控,吃得比平时多)、限制性饮食(限制食物摄入以控制或减轻体重)和补偿性行为(抵消暴食后体重增加的行为,如催吐、禁食、多运动等)的概率。

The first problem considered in this article reads： is it possible to find upper estimates for the spanning tree congestion in bipartite graphs, which are better than those for general graphs？ It is proved that there exists a bipartite version of the known graph with spanning tree congestion of order n3/2, where n is the number of vertices. The second problem is to estimate spanning tree congestion of random graphs. It is proved that the standard model of random graphs cannot be used to find graphs whose spanning tree congestion has order greater than n3/2.

To improve the mechanical properties of the Y_(2)O_(3)-added W alloy,mo and Zr were independently added to a sample of W-Y_(2)O_(3).In this study,the effects of minor additions of elemental mo and Zr on He bubble formation in the Y_(2)O_(3)added W alloys were investigated at 773 K,973 K,and 1173 K,where the maximum irradiation fluence of the samples using 5 keV He ions was 1.8×10^(21) He m^(−2).He bubbles were observed at all temperatures for both alloys;however,the irradiation fluences at which He bubbles could be observed differed at each *** increase in irradiation temperature,the He irradiation fluence for which the formation of He bubbles could be observed *** the relatively low temperature of 773 K,the void swelling in the W-mo-Y_(2)O_(3)and W-Zr-Y_(2)O_(3)alloys was slightly lower than that of W-Y_(2)O_(3)***,at high temperature of 973 K and 1173 K,the He irradiation resistances of both W-mo-Y_(2)O_(3)and W-Zr-Y_(2)O_(3)were worse than that of W-Y_(2)O_(3).The addition of Zr enhanced the interaction between vacancies and He,enhancing the formation of He ***,the addition of mo coarsened the Y_(2)O_(3)particles,reducing the suppression of vacancy cluster formation due to the dispersion of Y_(2)O_(3)*** is,therefore,necessary to fully consider mechanical properties and T-retention in addition to the irradiation resistance of He to select an alloy as the plasma-facing material for fusion applications.

The reproductive potential of overwintering boll weevil, Anthonomus grandis grandis （Boheman）, females collected from pheromone traps in september, November and January, fed for 1, 3, and 5 weeks on plant pollens, and then provided cotton squares, was determined in the laboratory at 27 ~ I^C, 65% RH, and a photoperiod 13 ： 11 （L ： D） h. Duration of pollen feeding by overwintering boll weevils did not significantly influence egg and feeding punctures, or puncture ratios （egg to total punctures） for any of the three months of parent weevil collections when provided cotton squares on a daily basis. However, punctures and puncture ratios are significantly different when comparing mean data between months of boll weevil collections. When boll weevils were provided with cotton squares daily, the pre-ovipositional periods of female parents captured in september, November and January were 5, 9 and 14 days, respectively. The rate of eggs by females was significantly lower during November and January than september. Female parents collected in september produced a significantly higher percentage of eggs yielding adult progeny than those collected in November and January. Life table parameters indicated that net reproductive rate （Ro） of boll weevil females collected in september was 1.2- fold higher than those collected in November and 10.7-fold higher than those collected in January. Except for testes size, no differences in male reproductive parameters were observed during the cotton-free period compared with males captured during mid-cotton （June）. The number of oocytes in the ovarioles and the number of ooeytes containing yolk were significantly lower during september, November and January compared with June. The reproductive potential ofoverwintering boll weevil females collected in different months is an important consideration in determining the success of any control strategy.

In this talk, I present the results on the pole structure of pion-nucleon scattering in an analytic model based on meson exchange. The analytic properties of scattering amplitudes provide important information. Besides the cuts, the poles and zeros on the different Riemann sheets determine the global behavior of the amplitude on the physical axis. Pole positions and residues allow for a parameterization of resonances in a well-defined way, free of assumptions for the background and energy dependence of the resonance part. This is a necessary condition to relate resonance contributions in different reactions.
