系统级封装(SiP)技术已广泛应用于移动设备、可穿戴设备、健康和医疗设备、人工智能(AI)、物联网(IoT)和汽车电子。SiP采用异构集成的方式,将各种芯片和元件集成到一个封装中,以实现特定功能,并具有节省电路板空间、简化布局设计和降低制造成本等优势。随着电子组件的小型化发展方向不断持续,一些SiP已经发展成为模块或系统级模块(SiM),可以直接连接并安装到器件中。回顾了SiP从多芯片模块(MCM)、多芯片封装(MCP)到高级芯粒封装和共封装光学器件(CPO)的演变。未来几年,更多的SiP将变成SiM,直接连接器件或系统。

The recent approval of gene therapy products in Europe and Asia and the upsurge of gene therapy products in clinical trials signal the rebound of this technology not only for many orphan diseases but also for non-life threatening diseases. Following the success of induced pluripotent stem （iPS） cells in research, other modifed ex vivo gene therapies are also knocking on the door of the clinic. Historically, gene therapy has experienced many ups and downs and still faces many *** the past 10 years, many new ideas have been tried, and the goal of making this technology a more effective treatment modality through greater safety and control is coming within reach. The frst clinical trial of iPS cells has begun, and cell mediated gene therapy products have reached phase Ⅲ in some countries. The potential for tumorigenicity and immunogenicity are still concerns with these products, so physicians should understand the biological aspects of engineered cells in the clinic. In this review article, we attempted to provide a summary update of the current state of knowledge regarding this technology： that is, we reviewed products that have fnished clinical trials, are still in clinical trials and/or are at the research stage. We also focused on the challenges, future directions, and strategies for making this technology available in the clinic. In addition, the available measures for making gene therapy products safer are within the scope of this article. It is also important to understand the manufacturing process for gene therapy products, because cell characteristics can change during the cell expansion process. When physicians use gene therapy products in the clinic, they should be aware of the viability, temperature sensitivity and stability of these cells because biologic products are different from chemical products. Although we may not be able to answer all possible questions and concerns, we believe that this is the right time for physicians to increase th

In the context of climate change, planning for forest management goals becomes more complicated. Possible changes in precipitation, temperature, and CO2 can affect tree growth substantially and potential effects differ by species and region. However, integration of potential forest growth responses to these factors can be achieved using models. Because of the need to understand the range of forest growth forecasts and the strengths and limitations of different modeling approaches, I summarized results from 25 studies of forecasted forest responses over coming decades. Some models used statistical relationships between tree rings and climate to forecast growth responses to future climate, some simulated net photosynthesis of a standard forest canopy, and many used tree or stand growth models at various levels of mechanistic detail. In general, models that included CO2 responses predicted enhanced forest growth by 2100 across most of the commercial timberland areas of the US and Canada. For modest warming, most models showed growth enhancement in most regions. For hotter scenarios, many models and regions showed even more growth enhancement, but some regions such as the Southwest, mountain West, and southwestern Canada were predicted to experience drought stress and increased fire incidence, although projections in these regions were variable. Young stands, angiosperms, and early-successional species were predicted to exhibit the most positive responses. As a result, commercial harvest ages might be accelerated by several years, depending on species. Some simulations for the Midwest and Northeast US predicted a doubling or more of net primary productivity although other studies show a lesser response. Model runs that did not include mechanisms of CO2 fertilization showed positive growth responses in only limited cases and generally showed growth declines. There also was some evidence indicating the potential spread of forest into woodland at shrub or prairie ecotones.

Despite having a better understanding of the COVID-19 disease, we are facing significant challenges regarding behaviors that enforce the lack of adherence to public health recommendations including the use of face masks and vaccine acceptability. Lessons learned from the 1918 flu pandemic, highlight the importance of wearing a face mask in conjunction with adherence to other public health recommendations. There are two key factors that influence how our communities are translating scientific evidence, denialism and ignorance. Sadly, a real consequence of this pandemic among a significant number of patients with COVID-19 disease is denial. As health care providers we need to take part in addressing these issues and educate our communities especially during this time where we see a second and larger uptake of COVID-19 cases. Fighting denialism and ignorance represents a significant challenge to our society and could have a substantial positive impact on helping with vaccine acceptability and other public health recommendations.

In this paper, we implement a content authoring and cloud system for cloud-based smart cloud learning. With the advent of the smartphone and mobile devices such as tablets, the educational paradigm is also changing. Was using the computer to aid in the learning e-learning started in ICT education are evolving Over the variety, in recent years, combines smart learning and social learning, cloud-based smart devices in e-learning the concept of Smart Cloud Smart Education Services Learning was gives rise to the term. Smart Cloud and free running is always the knowledge content uploaded by anyone, anywhere, can also be shared with other users. A terminal and location, without limitations on time, are continuously available to the environment of a high- quality knowledge content was coming through a variety of smart media, open educational content platform is built over the level of the possible conditions than e-learning. In this paper, we develop applications and Web sites that can provide authored content for smart cloud learning. In addition, we have built the cloud for content management and the website that can share content with other users. In the future, should wish to study a way that can provide customized services over the learner analysis based on big data technology.
