The mid-Pleistocene transition （MPT, c. 1.2 to 0.5 Ma） records fundamental changes in Earth＇s climate state, where low-amplitude 41-kyr obliquity-dominated cycles gave way progressively to the high-amplitude, quasiperiodic （c. 100-kyr） fluctuations that characterize the later Pleistocene and Holocene. We use wavelet analysis on the LR04 δ^l8O benthic foraminiferal stack to confirm low-frequency power as early as 1.25-1.20 Ma, determine the persistence of obliquity-dominated cyclicity through and beyond the MPT, and reveal new levels of complexity in climate evolution.

A challenging task when applying high-order digital modulation schemes is the complexity of the detector. Particularly, the complexity of the optimal a posteriori probability （APP） detector increases exponentially with respect to the number of bits per data symbol. This statement is also true for the Max-Log-APP detector, which is a common simplification of the APP detector. Thus it is important to design new detection algorithms which combine a sufficient performance with low complexity. In this contribution, a detection algorithm for two- dimensional digital modulation schemes which cannot be split-up into real and imaginary parts （like phase shift keying and phase-shifted snperposition modulation （PSM）） is proposed with emphasis on PSM with equal power allocation. This algorithm exploits the relationship between Max-Log-APP detection and a Voronoi diagram to determine planar surfaces of the soft outputs over the entire range of detector input values. As opposed to state-of-the-art detectors based on Voronoi surfaces, a priori information is taken into account, enabling iterative processing. Since the algorithm achieves Max-Log-APP performance, even in the presence of a priori information, this implies a great potential for complexity reduction compared to the classical APP detection.

Food security is a global concern in view of the ongoing global （social and climate） change. The challenges to food securityfrom global change, sharply increasing food and feed demands, whereas increasing the frequency and severity of stresses,coupled with degradation and scarcity of natural resources, are indeed urgent and real （Prasanna et al. 2013）. Crop productionmust double by 2050 to meet future production demands （Tilman et al. 2011）. The ability to achieve this increaserepresents a significant challenge to plant breeders. Crop yields must increase at a rate of 2.47o per year, yet the averagerate of increase is only 1.3% with yields stagnating in up to 40% of land under cereal production （Ray et al. 2012, 2013）. Therefore,crops with higher yield potential and more resistant to abiotic stress conditions are needed to address such challenges.

轮胎行业正致力于发展节能轮胎和环保轮胎。为了实现这一目标,需要面临一些制造技术方面的挑战。美国PPG工业公司提出的材料解决方法,可以同时解决这一系列的挑战。该方法体现为两个技术平台——即Hi-Sil沉淀法白炭黑和Agilon功能白炭黑。Hi-Sil EZ160G-D白炭黑(+原位硅烷偶联剂)可在一定程度上减少能量损耗,降低生热,还可提高抗降解效果;Agilon400 G-D功能白炭黑可大大减少能量损耗,降低生热,提高燃油效率,还可保持和/或提高抗降解效果,大大改善贮存稳定性和挤出收缩率,解决了原有传统白炭黑+原位硅烷偶联剂体系在制造技术方面的问题。
