Evolution Strategy Optimization for Selective Pulses in NMR

We present a first set of improved selective pulses, obtained with a numerical technique similar to the one proposed by Geen and Freeman. The novelty is essentially a robust and efficient “evolution strategy” which consistently leads, in a matter of minutes, to “solutions” better than those published so far. The other two ingredients are a “cost function,” which includes contributions from peak and average radiofrequency power, and some understanding of the peculiar requirements of each type of pulse. For example, good solutions for self-refocusing pulses and “negative phase excitation pulses” (which yield a maximum signal well after the end of the pulse) are found, as may have been predicted, among amplitude modulated pulses with 270° tip angles. Emphasis is given to the search for solutions with low RF power for selective excitation, saturation, and inversion pulses. Experimental verification of accuracy and power requirements of the pulses has been performed with a 4.7 T Sisco imager.

优质猪肉供应链中养猪场的行为选择机理及其优化策略研究

实施供应链管理是优质猪肉生产的有效途径,养猪场行为是决定猪肉产品质量安全的关键.本文依据博弈理论和方法,分析了优质猪肉供应链中养猪场和公司行为选择的机理,导出了双方行为选择的混合战略纳什均衡点.研究表明:降低风险偏好、监督成本和违约超常收益,增加违约惩罚、违约潜在损失、违约信用损失、供应链内外收益差和合作期限,是优化养猪场行为选择的有效途径,据此从强制性和诱致性两种作用入手提出了6种基本优化策略.     

The Impact of Specific Exertion on the Efficiency and Ease of the Voice: A Pilot Study

Even though most singers and other professional voice users are encouraged to relax to optimize the quality and performance of the voice, observations of acclaimed singers, actors, and public speakers would suggest otherwise. These successful vocal performers appear to be energized, actively working and exerting themselves. For this reason, a study was designed to explore the role of exertion in maintaining and optimizing the voice. The focus of this study was the possibility that increasing exertion could improve the voice and might result in the voice user experiencing less strain and, therefore, more comfort and ease. Ten subjects were recorded before and after completing a workshop to develop their skills with precise use of effort involving selected parameters of the larynx and vocal tract. Self-reported ratings of degree of exertion and level of comfort were collected at the time of each recording. The preworkshop and postworkshop recordings were analyzed acoustically and perceptually to compare the degree of noise in the signal that corresponds with the efficiency of the voice. The results indicated that, for all subjects, the quality of the voice improved with an increase in the use of specific exertion. Furthermore, ease and comfort also significantly increased.
