至今,在使用显式外推算子的叠前深度偏移中都忽略了地震波的衰减和弥散。本文介绍了一种在深度偏移方案中考虑吸收和弥散效应的方法。用一种最优化算法来设计补偿吸收和弥散的外推算子。设计的原则是算子的波数响应应该等于理想的外推算子,在波场外推中同时使用相速度和吸收宏观模型。在有中等—强吸收性的介质模型中,使用该方法所得到的图像要好于那些用没有补偿吸收的外推算子得到的图像。

Data centers are often equipped with multiple cooling units. Here, an aquifer thermal energy storage (ATES) system has shown to be efficient. However, the usage of hot and cold-water wells in the ATES must be balanced for legal and environmental reasons. Reinforcement Learning has been proven to be a useful tool for optimizing the cooling operation at data centers. Nonetheless, since cooling demand changes continuously, balancing the ATES usage on a yearly basis imposes an additional challenge in the form of a delayed reward. To overcome this, we formulate a return decomposition, Cool-RUDDER, which relies on simple domain knowledge and needs no training. We trained a proximal policy optimization agent to keep server temperatures steady while minimizing operational costs. Comparing the Cool-RUDDER reward signal to other ATES-associated rewards, all models kept the server temperatures steady at around 30 °C. An optimal ATES balance was defined to be 0% and a yearly imbalance of −4.9% with a confidence interval of [−6.2, −3.8]% was achieved for the Cool 2.0 reward. This outperformed a baseline ATES-associated reward of 0 at −16.3% with a confidence interval of [−17.1, −15.4]% and all other ATES-associated rewards. However, the improved ATES balance comes with a higher energy consumption cost of 12.5% when comparing the relative cost of the Cool 2.0 reward to the zero reward, resulting in a trade-off. Moreover, the method comes with limited requirements and is applicable to any long-term problem satisfying a linear state-transition system.

Asian Journal of Andrology 2010年第1期12卷 26-32页

作者： rune Eliasson Bjornstigen 13 SE 165 71 HASSELBY Sweden

The new World Health Organization （WHO） Manual for Semen Analysis contains several improvements. One is that the 20 million spermatozoa per mL paradigm has been ousted in favour of proper calculations of lower reference limits for semen from men, whose partners had a time-to-pregnancy of 12 months or less. The recommendation to grade the progressive motility as described in the third and fourth editions of the WHO manual was not evidence-based, and WHO was therefore motivated to abandon it. However, the new recommendation is not evidence-based either, and it is difficult to understand the rational for the new assessment. It may have been a compromise to avoid returning to the rather robust system recommended in the first edition （1980）. The unconditional recommendation of the ＇Tygerberg strict criteria＇ is not evidence-based, and seems to be the result of an unfortunate bias in the composition of the Committee in favour of individuals known to support the ＇strict criteria＇ method. This recommendation will have negative effects on the develop- ment ofandrology as a scientific field. Given the importance of the WHO manual, it is unfortunate that the recommenda- tions for such important variables, as motility and morphology, lack evidence-based support.
