A 660MHz ZVS DC-DC converter using gate-driver charge-recycling in 0.18μm CMOS with an integrated output filter

The design and manufacture of a prototype chip level power supply is described, with both simulated and experimental results. Of particular interest is the inclusion of a fully integrated on-chip LC filter. A high switching frequency of 660MHz and the design of a device drive circuit reduce losses by supply stacking, low-swing signaling and charge recycling. The paper demonstrates that a chip level converter operating at high frequency can be built and shows how this can be achieved, using zero voltage switching techniques similar to those commonly used in larger converters. Both simulations and experimental data from a fabricated circuit in 0.18μm CMOS are included. The circuit converts 2.2V to 0.75∼1.0V at ∼55mA. ©2008 IEEE.

Anchors, scales and the relative coding of value in the brain.

People are alarmingly susceptible to manipulations that change both their expectations and experience of the value of goods. Recent studies in behavioral economics suggest such variability reflects more than mere caprice. People commonly judge options and prices in relative terms, rather than absolutely, and display strong sensitivity to exemplar and price anchors. We propose that these findings elucidate important principles about reward processing in the brain. In particular, relative valuation may be a natural consequence of adaptive coding of neuronal firing to optimise sensitivity across large ranges of value. Furthermore, the initial apparent arbitrariness of value may reflect the brains' attempts to optimally integrate diverse sources of value-relevant information in the face of perceived uncertainty. Recent findings in neuroscience support both accounts, and implicate regions in the orbitofrontal cortex, striatum, and ventromedial prefrontal cortex in the construction of value.

无机阴离子在涂敷十六烷基吡啶的C_(18)键合相柱上的分离和测定

<正> 近年来,离子相互作用色谱法得到了迅速发展,使用这种方法,不仅可用有机树脂作固定相,同样可使用高效的键合固定相,并且可以通过改变离子相互作用,试剂在流动相中的浓度或涂敷在固定相上的量来改变柱的交换容量。实验使用常规的液相色谱仪,易于方法的广泛应用。在无机阴离子的分离中,这一方法显示了优越的分离效率。 本文研究了在涂敷十六烷基吡啶的C_8键合固定相上分离无机阴离子,并利用一些无机阴离子在

三种淡水枝角类生物学的研究

在恒温条件下,观察了平突船卵潘、隆线溞、微型裸腹溞的生长和繁殖。这三种淡水枝角类的生长随龄数的增加而变慢;总生活时间随温度升高而缩短。 平突船卵溞在20℃时,有3个幼龄、18个成龄、总生活时间为46.8天;30℃时为3个幼龄、15个成龄和18.8天。30℃时,隆线溞有3个幼龄、14个成龄、总生活时间为18.7天;微型裸腹溞则为2个幼龄、9个成龄和10.7天。 种类不同,累计产卵数相差很大。隆线溞在30℃时高达366个;微型裸腹溞仅为48个。平突船卵溞在20℃和30℃时分别为178个和172个。产卵率以隆线

Isolation and characterization of 18 polymorphic microsatellite markers in Chinese mandarin fish Siniperca chuatsi (Basilewsky)

Eighteen microsatellite markers were isolated and characterized using an enrichment protocol in the Chinese mandarin fish Siniperca chuatsi (Basilewsky), a commercially important piscivorous fish in China. Out of 48 pairs of primers designed, 18 loci exhibited polymorphism with three to six alleles (mean 4.4 alleles/locus) and average observed heterozygosity ranged from 0.633 to 0.833 (mean 0.748) in a test population from Dongting Lake of China. Except for two loci, all other 16 loci were in the Hardy-Weinberg equilibrium. These markers would be useful for such studies as population genetics, ecology and selective breeding of the Chinese mandarin fish in future.
