作者： dougherty steven t Department of Mathematics University of Scranton ScrantonPA 18510 USA

In this paper,we generalize the concept of type Ⅱ codes to arbitrary finite rings. We focus on type Ⅱ codes over finite chain rings and use the Chinese Remainder theorem on these codes to study type Ⅱ codes over pr... 详细信息

CYCLIC CODES OVER FORMAL POWER SERIES RINGS

引用

Acta Mathematica Scientia 2011年第1期31卷 331-343页

作者： dougherty steven t. 刘宏伟 Department of Mathematics University of Scranton Department of Mathematics Huazhong Normal University

In this article, cyclic codes and negacyclic codes over formal power series rings are studied. the structure of cyclic codes over this class of rings is given, and the relationship between these codes and cyclic codes over finite chain rings is obtained. Using an isomorphism between cyclic and negacyclic codes over formal power series rings, the structure of negacyclic codes over the formal power series rings is obtained.

Annual rings from 30 year old vines in a California rootstock trial were measured to determine the effects of 15 different rootstocks on Chardonnay and Cabernet Sauvignon *** traits measuring vegetative growth,yield,berry quality,and nutrient uptake were collected at the beginning(1995 to 1999)and end(2017 to 2020)of the lifetime of a vineyard initially planted in 1991 and removed in 2021.X-ray Computed tomography(Ct)was used to measure ring widths in 103 *** width was modeled as a function of ring number using a negative exponential *** and late wood ring widths,cambium width,and scion trunk radius were correlated with 27 *** of annual ring width shows that scions alter the width of the first rings but that rootstocks alter the decay of later rings,consistently shortening ring width throughout the lifetime of the *** index,juice pH,photosynthetic assimilation and transpiration rates,and instantaneous water use efficiency are correlated with scion trunk ***,our research indicates that rootstocks modulate secondary growth over years,altering physiology and agronomic *** act in similar but distinct ways from climate to modulate ring width,which borrowing techniques from dendrochronology,can be used to monitor both genetic and environmental effects in woody perennial crop species.

试验利用了8头安格斯半同阉牛(X=270千克),在3个成熟期(再生草24、40和47天),4个牧草DM供给量(1.0、1.5、2.0和2.5千克/100千克活重),在每段放牧时间(2天)对它们的采食行为进行了研究。采用拴系放牧制,每头阉牛及其采食小区为一个试验单位,8和14点开始放牧。采食量直线增加,DM从1千克/100千克活重时的1.98千克增至2.5千克,尽管牧草的利用由0.69降至0.43,但每口采食的DM却从1千克/100千克活重的供给量时的1.0克
