The erase voltage impact on the 0.18μm triple self-aligned split-gate flash endurance is *** optimized erase voltage is necessary in order to achieve the best endurance.A lower erase voltage can cause more cell current degradation by increasing its sensitivity to the floating gate voltage drop,which is induced by tunnel oxide charge trapping during program/erase cycling.A higher erase voltage also aggravates the endurance degradation by introducing select gate oxide charge trapping.A progressive erase voltage method is proposed and demonstrated to better balance the two degradation mechanisms and thus further improve endurance performance.

Announced in 2010 at the International AIDS Conference in Vienna and pioneered by the Joint United Nations Programme on HIV/AIDS (UNAIDS) and the World Health Organization's (WHO) leadership at the global level, Treatment 2.0 is a new approach to the HIV response that encourages innovation, efficiency, and sustainability. Building upon WHO and UNAIDS' '3 by 5' Initiative, Treatment 2.0 focuses upon scale-up and universal access of life-saving ART treatment through strategic investments and innovations in five priority pillars that include: 1) Optimize drug regimens, 2) Provide point-of-care (POC) and other simplified diagnostic and monitoring tools, 3) Reduce costs, 4) Adapt service delivery, and 5) Mobilize communities [1-3]. The Treatment 2.0 approach is in line with UNAIDS' 2011-2015 Strategy: Getting to Zero with the vision of, 'Zero New infections;Zero discrimination;and Zero AIDS-related deaths', and as well as the four strategic directions for the health sector response outlined under WHO's Global Health Sector Strategy on HIV/AIDS 2011-2015 [4,5]. At the Sixty-fourth World Health Assembly (WHA) in May 2011, it was formally announced that Vietnam has taken the leadership to pilot Treatment 2.0 in two of its provinces, with support from both the WHO and UNAIDS country offices [6,7]. Given that Vietnam is one of the few countries with a concentrated epidemic to pilot Treatment 2.0, the outcomes and experiences of this initiative can provide valuable insight to other countries who may consider implementation. The objectives of this article are therefore to: 1) Describe the early process for translating Treatment 2.0 concept in Vietnam's context;and 2) Highlight early progress and challenges.

我们开发了一种新型可配置逻辑阵列测试结构,它采用高度可伸缩且兼具功耗低和配置时间短两大优势的第3代分离栅极闪存单元。此分离栅极Super Flash配置元件(SCE)已通过90nm嵌入式闪存技术进行了演示。得到的SCE消除了对深奥的制造工艺、检测和SRAM电路的需求,并缩短了可编程阵列(PA)(例如,FPGA和CPLD)的配置时间。此外,SCE本身还具有SST分离栅极闪存技术的优点,包括紧凑的区域、低电压读操作、低功耗多晶硅间(pol y-t o-pol y)擦除、源极侧通道热电子(SSCHE)注入编程机制以及超高的可靠性。

The amount of tunnels excavated along stratified/sedimentary rock masses in Quangninh coal mine area,Vietnam, is gradually increasing. Rock mass in Quangninh is characterized by beddings between rock layers. The behavior of stratified rock masses surrounding the tunnels depends on both the intact rock and the beddings between rock layers. The main characteristics of stratified rock masses that need to be considered are their heterogeneity and anisotropy. Depending on the dip angle of rock layers, movements and failure zones developed surrounding the tunnels can be asymmetrical over the vertical axis of tunnel. This asymmetry causes adverse behaviors of the tunnel structures. The objective of this study is to highlight convergences and yielded zones developed in rock masses surrounding noncircular tunnels in Quangninh coal mine area using a finite element method. The presence of bedding joints is explicitly simulated. The numerical results indicated that with the increase in dip angle of bedding joints, the stress asymmetry over the tunnel vertical axis increases. It gradually leads to an asymmetry of the failure zone surrounding the tunnel. An increase of rock mass quality means a decrease of rock mass sensitivity to the discontinuities. In addition,a dip angle of the bedding joints of approximately 45° could be considered as the critical angle at which the rock mass mechanism changes between sliding and bending.
