Total ionizing dose effect in an input/output device for flash memory

Input/output devices for flash memory are exposed to gamma ray irradiation. Total ionizing dose has been shown great influence on characteristic degradation of transistors with different sizes. In this paper, we observed a larger increase of off-state leakage in the short channel device than in long one. However, a larger threshold voltage shift is observed for the narrow width device than for the wide one, which is well known as the radiation induced narrow channel effect. The radiation induced charge in the shallow trench isolation oxide influences the electric field of the narrow channel device. Also, the drain bias dependence of the off-state leakage after irradiation is observed, which is called the radiation enhanced drain induced barrier lowing effect. Finally, we found that substrate bias voltage can suppress the off-state leakage, while leading to more obvious hump effect.

PERFORMANCE ANALYSIS OF ATM SWITCH FABRIC WITH COMBINED-INPUT/OUTPUT BUFFERING

This paper analyses the performance of the ATM switch fabric with Combined-Input/ Output Buffering(C-IOB) under two different service principles for the cells at the head of line (HOL) positions of input buffers: First Come First Service (FCFS)/Random Service(RS) for the set of HOL cells addressed to a given output port with different/same "age" (the waiting time at the HOL position) and Pure Random Service(PRS) for all HOL cells addressed to a given output port regardless of their "ages" while the Queue Loss (QL) transfer scheme is adopted for interaction between input and output buffers in the ATM switch fabric. The results obtained show that the C-IOB ATM switch fabric with PRS service policy and the QL transfer scheme is better than other buffering ATM switch fabrics.

基于超效率Output-DEA模型的主产区粮食生产能力评价

应用超效率Output-DEA模型,对我国2008年13个粮食主产省区的粮食生产能力进行了研究。结果表明,主产区处于技术有效的省份仅有4个,其超效率值存在较大差距。多数省区技术无效率是规模效率低造成的。如果能够提高无效率省区的技术效率,发挥有效率省份的生产潜力,对提升全国的粮食生产能力将产生十分明显的效果。各无效率省区还存在投入的冗余,减少这些投入冗余对于降低粮食生产成本具有重要作用。我国政府应该把提高粮食生产效率作为粮食政策的首要目标,促进粮食生产区域的合理布局,优化粮食生产支持政策。

Loss Rate Estimation of Yield and Output Value of Tobacco Leaf Infected by Tobacco Blown Spot (Alternaria alternata)

[Objective] The paper was to study the effect of tobacco blown spot on the yield and output value of tobacco leaf.[Method]The upper,middle and lower leaves in tobacco plant were selected during the harvest period of tobacco to carry out loss rate estimation of yield and output value of tobacco leaf caused by different disease levels of brown spot.Regression correlation analysis was also conducted.[Result]The disease levels of brown spot had extremely significant strong negative correlation with single leaf weight of tobacco leaf,and it had extremely significant strong positive correlation with the loss rate of single leaf weight.The increase speed of loss rate of single leaf weight of middle and upper leaves was obviously faster than that of lower leaves.The loss rates of single leaf weight of upper,middle and lower leaves were 3.18%-28.95%,3.43%-28.88% and 10.07%-26.90%,respectively.The higher the disease level of blown spot was,the lower the yield and output value of tobacco leaf was,and the corresponding loss rate was also higher.Correlation analysis showed that the disease level of blown spot had extremely significant strong negative correlation with the yield and output value of tobacco leaf,and it had extremely significant strong positive correlation with the loss rate of yield and output value.The negative impact of blown spot on the output value of tobacco leaf was far greater than that on the yield.The highest loss rate of the yield of tobacco leaf was 28.56%,while the highest loss rate of output value reached 89.67%.[Conclusion] The study provided theoretical basis for accurately holding the critical period for the control of blown spot,thus reducing the damage on tobacco leaf and improving the output value of tobacco leaf.

A four-dimensional model for the information storage/output of life

A large amount of progress has achieved in neuroscience,however,there is still a lack of reasonable model for the storage/output(S/O)of life information.The cyclical motion of cardio-and pulmonary-myocyte is a typical process of the life information S/O,while the opening and closing sites of Ca^(2+)ion channels during the motion can form a genetically programmed time-dependent three-dimensional(3D)pattern.Those phenomena indicate a strong correlation of the information S/O model of these myocytes with the time-sequence 3D patterns.Therefore,based on the time-dependent Ca^(2+)fluorescence imaging during the motion of cardio-and pulmonary-myocyte,here we suggest a four-dimensional(4D)code of information S/O model in cell and nervous system.Further from the fact of pulmonary myocyte motion able to be controlled by brain,it is deduced that the 4D code in brain has a role of controlling muscles through a pathway of the central nervous system,peripheral nervous system,neuromuscular junction,and muscle cells.In addition,we also suggested the 4D code of non-innate skill that can be programmed by the learning/training of a long time(~3 years),such as walking,writing,painting,sports,speech,singing,and dancing.Noticeably,this 4D S/O model is reasonable for the ultralow energy consumption of life information transmission.

The Role of Output in Grammar Learning

In China, English teachers tend to emphasize a lot on the importance of grammar learning because knowledge of grammar is the base of the competence of communication. This thesis just focuses on how output affects students' grammar learning by analyzing the role of output in learning of English and the strategies of English learning.

The Effects of Noticing Function of Output on Second Language Acquisition

Swain's(1985) "Output Hypothesis"maintains that output performsthree functions,namely,the"noticing/triggering function",the"hypothesis-testing"function,and the " metalinguistic" function.Based on the " Noticing Hypothesis",this study aims to investigate the role of the noticing function of output in second language acquisition.The major findings of this research are summarized as follows:1) when composing,the learner could notice linguistic problems in their ineterlanguaeamong which problems arising from vocabulary and sentence were the most prominent.2) with more attention paid to vocabulary,the learner could notice linguistic forms of various aspects when comparing their original text to the modelsof writing.And they could partially incorporate what they hadnoticed in models into their subsequent revision.3) through models of writing learning,the EG learners performed better than the CG learnersin error correction in Composition2,which proves that output with subsequent input learning has superiority over output without relevant input followed in facilitatingthe acquisition of accuracy of linguistic forms.

From Input to Output-Exploring the Role of Intake in English Learning

This paper aims to explore the role of intake in second language learning.Based on her literature review and the case of an English lesson in a Chinese secondary school,the author argues that L2 acquisition does not take place directly from input to output.In each sqecific part of L2 acquisition process,intake plays various important roles such as filtering,facilitating in comprehensible input and processing in pushed output.In the Chinese foreign language teaching context,it is also found that L2 acquisition is an arduous task for learners to extract information from the input,utilize it in forming a grammar and produce target language forms accurately and fluently.It is the same with L2 teachers who need to play their roles of a controller,a corrector,an organizer and a prompter in the learning process.

The Importance of Output in SLA and Its Pedagogical Implications

Input and output in second language acquisition are closely related. Input is the essential preparation for output, while output is the purpose of input, and in turn promotes input. They complement each other and help to improve students' linguistic competence. Comprehensible input and output are equally important in language learning. Therefore, it is unwise to ignore the roles of output in pedagogical situation.
