A Kernel-Based Convolution Method to Calculate Sparse Aerial Image Intensity for Lithography Simulation

Optical proximity correction (OPC) systems require an accurate and fast way to predict how patterns will be transferred to the wafer.Based on Gabor's 'reduction to principal waves',a partially coherent imaging system can be represented as a superposition of coherent imaging systems,so an accurate and fast sparse aerial image intensity calculation algorithm for lithography simulation is presented based on convolution kernels,which also include simulating the lateral diffusion and some mask processing effects via Gaussian filter.The simplicity of this model leads to substantial computational and analytical benefits.Efficiency of this method is also shown through simulation results.

Nurse trainees' perception of effective clinical instructor characteristics

Objectives:Clinical education and experience in the clinical environment play an important role in shaping the clinical experience.Effective clinical teaching improves the clinical practice of the nursing trainees which in turn improves the quality of patient care.It mandates for the clinical instructor with desired qualities,to have a positive influence in clinical education.This study examined nurse trainees'perceptions of clinical instructor characteristics.Methods:The current study was conducted in a multi-cultural tertiary setting using a cross-sectional descriptive design.Using convenience sampling,302 trainees were chosen as participants for the study,and there were 296 respondents.The data were collected from the participants using the Nursing Clinical Teacher Effectiveness Inventory(NCTEI)tool.Results:The findings of the study revealed that the clinical instructors have scored high in personality(scoring percentage=84.0%)and relatively low in teaching ability(scoring percentage=81.3%).Also,the overall perception was almost the same among all the trainees though there was a slight variation in their rating of each dimension.Conclusions:Nursing trainees indicated the instructors as having good personality and relatively low teaching ability.This mandates the clinical instructors in the clinical environment to empower themselves in this area of improvement.This helps the teaching institutions to consider all the domains of effective clinical instructor characteristics while recruitment and also organize programs giving emphasis on building and developing these characteristics to create effective instructors.

NEW METHOD TO RECOVER INTERNET PACKET LOSSES USING(2,1,m)SYSTEMATIC CONVOLUTIONAL CODES

A new method to recover packet losses using (2,1,m) convolutional codes is proposed. The erasure correcting decoding algorithm and the decoding determinant theorem is presented. It is also proved that the codes with optimal distance profile have also optimal delay characteristic. Simulation results show that the proposed method can recover the packet losses more elliciently than RS codes over different decoding delay conditions and thus suits for different packet network delav conditions.

Investigations and thoughts of the ethics in genetic discrimination

A questionnaire research in ethics was conducted to get the view of students of medical universities in Shanghai on genomics and genetic discrimination. We find that 66% respondents indicated their willingness to understand the genetic information and 79% of respondents mind their own genetic information be aware of by other people. In contrast, 77% of the respondents believe that medical organization are not able to protect personal genetic information from disclose. Hence, it is significant to take some measures to preserve citizen's genetic information privacy. Depending on our results, we put forward our suggestion to this problem.

Modelling the upwelling off the east Hainan Island coast in summer 2010

A synoptic-scale upwelling event that developed off the east coast of the Hainan Island（EHIU） in the summer of 2010 is defi ned well via processing the Moderate Resolution Imaging Spectroradiometer（MODIS） sea surface temperature（SST） data. The Regional Ocean Modeling System（ROMS） with high spatial resolution has been used to investigate this upwelling event. By comparing the ROMS results against tide station data, Argo fl oat profi les and MODIS SST, it is confi rmed that the ROMS reproduces the EHIU well. The cooler-water core（CWC） distinguished by waters（27） 27.5℃ in the EHIU, which occurred in the east Qiongzhou Strait mouth area and was bounded by a high temperature gradient, was the focus of this paper. Vertical structure of the CWC suggests that interaction between the westward fl ow and the bathymetry slope played a signifi cant role in the formation of CWC. Numerical experiments indicated that the westward fl ow in the Qiongzhou Strait was the result of tidal rectifi cation over variable topography（Shi et al., 2002）, thus tides played a critical role on the development of the CWC. The negative wind stress curl that dominated the east Qiongzhou Strait mouth area suppressed the intensity of the CWC by 0.2–0.4℃. Further, nonlinear interaction between tidal currents and wind stress enhanced vertical mixing greatly, which would benefi t the development of the CWC.

实施“高考制+申请制”并行运作的高考招生改革构想

本文依据教育与心理测量学理论和方法，对目前高等教育“大众化阶段”的高考形式进行了深入剖析。在此基础上提出了变革传统的“千校一卷”的高考形式，实施“高考制＋申请制”并行运作的高考招生制度改革构想；即将高职高专招生考试从目前的高考体制中剥离出来，使高考分为两个层次，一是“本科层次”；二是“高职高专院层次”对应目前的高考制度，前者为常模参照考试，主要体现高考的选拔功能；后者为标准参照考试，用申请制替代目前的高考制度。
