基于ThorLAT栅格计算程序,以统一慢化方程形式实现了子群法、嵌入式自屏法(Embedded Self-Shielding Method,ESSM)、Tone和考虑不同燃料区影响的Tone-N共振计算方法。采用SHEM361能群结构,通过反应堆应用虚拟环境(Virtual Environment for Reactor Applications,VERA)组件基准题和熔盐堆燃料栅元基准题对ThorLAT中实现的各类共振计算方法进行了验证和分析。在VERA组件基准题中,有效增殖因子keff及棒功率与参考解均符合较好。对于熔盐堆燃料栅元基准题,基于均匀共振积分表插值的ESSM和Tone方法计算精度较高,且在存在温度分布的算例中计算精度和效率均优于不相关模型和全相关模型的子群法。Tone-N与Tone方法得到的熔盐堆燃料栅元基准题计算结果基本相同,说明了在Tone方法中使用均匀截面假设的合理性。相比XMAS172能群结构,SHEM361能群结构通过体现可分辨共振能区更精细的能谱来有效改进精度。上述结果初步表明,SHEM361能群结构下基于均匀共振积分表插值的ESSM和Tone方法可用于熔盐堆共振计算。

Objective: To identify the effect of dyslipidemia on auditory function detected by Pure Tone Audiometry. To check if dyslipidemia worsens the hearing level in diabetics.Design: This was a comparative study where 120 subjects between the age group of 20 and 50 years underwent pure Tone audiometry, lipid profile and blood sugars. Group 1 consisted of 30 subjects with type 2 diabetes and dyslipidemia; Group 2 had 30 subjects with isolated diabetes;Group 3 had 30 with isolated dyslipidemia and Group 4 included 30 normal subjects as control.Results: Significant hearing loss was seen only in the group with isolated diabetes(63%). The most common type of hearing loss was high frequency sensorineural hearing loss. When comparison was made between the combinations of different lipid profiles, no association was found to the level of hearing.Conclusions: Diabetics are more prone to high frequency hearing loss. Altered lipid profile has no role in causing hearing loss.

We investigate whether pledgee competition affects the disclosure choice of firms whose controlling shareholders pledge their shares.We find that pledgee competition is positively related to pledge firms’ annual report Tone management.This positive relationship is stronger for pledge firms with lower credit quality and non-state-owned enterprise pledge firms.Further corroborating our results, higher pledgee competition increases the future crash risk of pledge firms.Collectively, our results suggest that competition pressure induces pledgees to lower their monitoring incentives to remain competitive in the marketplace, thus leading to pledge firms’ bad news hoarding behavior.

Background: Narcolepsy type 1 is a sleep disorder characterized by excessive sleepiness along with cataplexy and/or hypocretin deficiency. We present a case of narcolepsy type 1 in which the cataplexy symptoms were reduced while on suboxone. Aim: This case report aims to note the reduction of cataplexy symptoms with suboxone. Case Presentation: A 39-year-old female patient with narcolepsy type 1 was referred to our pain clinic for management with suboxone. The patient had tried various other medications for the management of narcolepsy. With opioid management, the patient reported reduced cataplexy symptoms. Conclusion: The case illustrates the scientific thought that opioids could increase hypocretin and reduce symptoms in narcolepsy type 1.

急性低频感音神经性聋（acute low—Tone sensori—neural hearingloss，ALHL）是一种原因不明的急性起病并以低频听力损失为主不伴眩晕的感音神经性聋，患者主要以低调耳鸣、耳闷胀感、听力下降为主诉或症状。该病于1982年由Abe首次提出，但对其认识不足，起初认为是一种以低频听力下降为表现的轻度突发性聋。目前认为其是一种独立的疾病，有别于突发性耳聋，在临床并非少见，甚至有增多的趋势。本文通过对国内外相关文献的查阅，对该病近些年的发展从以下方面进行阐述。

This paper describes tonal contrasts in Xiuning Hui Chinese dialect in terms of a detailed acoustic phonetic analysis of F0 and duration data from 10 native speakers. There are 2 level Tones,2 rising Tones,1 falling Tone and 1 concave Tone in Xiuning. The results show that pitch levels and pitch contours both contribute to the characterization of Tones. And a detailed examination of tonal contours reveals that speakers may employ different articulatory strategies in tonal production. Phonological consequences are also discussed on the basis of the phonetic data.

Frontiers of Literary Studies in China-Selected Publications from Chinese Universities 2012年第3期6卷 393-409页

作者： Wenjin Cui Department of East Asian Studies New York University New York NY 10003 USA

With his insistence upon the literal rendering in Chinese of foreign texts, especially regarding syntax, Lu Xun＇s understanding of＂literal translation＂ strikes a rather distinct note in the modern Chinese literary scene. The intention behind this method, namely, the aim to ＂retain the Tone of the original,＂ reveals a generative perception of language that takes language as not just the bearer of the already existent thought, but as the formative element of thought that has meaning in itself. This paper seeks to delineate the structural constitution of the materiality of language as grasped by Lu Xun. By comparing the notion of the ＂Tone＂ to Wilhelm yon Humboldt＇s notion of the ＂inner form ~of language＂ and situating it within the genealogy of qi, as well as tracing its link with Zhang Taiyan＇s idea of＂zhiyan,＂ I will attempt to reveal the philosophical and historical basis of Lu Xun＇s principle of ＂literal translation＂ and its significance for Chinese literary modernity in general.

The modern multi-channel cochlear implants usually extract and encode the temporal envelope cues. This kind of algorithms can hardly satisfy the users who speak tonal languages, such as Mandarin. Many studies have tried to enhance the recognition ability of Mandarin through encoding tonal information and made suggestions to frequency-modulate the fixed pulse-rate carrier with the extracted tonal information based on the rate-pitch theory in electric hearing. However, how to encode and deliver the tonal information such as F0 by changing electric-stimulus rate has not got further study in clinical electric-stimulus mode. The present paper focuses on this matter by piecewise calculating the appreciable electric-stimulus rates. Then an electric-stimulus encoding algorithm of Mandarin Tone is brought forward and testified through acoustic simulations. Such conclusion can be drawn that this algorithm of electric-stimulus rate could convey tonal information well and help to enhance the Mandarin speech recognition ability.
