臺灣野生酵母菌之族群遺傳基因體學
為了解決ap-2318p 的問題，作者李佳燁 這樣論述：
Population genetics is the study of genetic variations within and between groups of individuals. With a long history of domestication, the budding yeast Saccharomyces cerevisiae is a great model for population, ecology and evolutionary studies, given that more than a thousand isolates have been col
lected from a wide range including both artificial and natural niches. Previous studies pointed to East Asia as the geographical origin of the species, where highly genetically diverse wild populations were discovered. Among them, three isolates from Taiwan revealed unprecedented divergence to popul
ations from the rest of the world. However, a lack of systemic survey and isolation in Taiwan limits our knowledge of the species’ distribution and diversity in nature. In the following chapters, I describe the fundamental ideas behind population genetic approach, strategies to sample broadly, and f
indings from the 121 isolates collected in Taiwan. Overall, S. cerevisiae is prevalent in diverse habitats in low abundance, contrary to their dominance in domesticated environments. Multiple coexisting and admixing natural lineages elevated the total genetic diversity within limited geographical ra
nge, comparable to that of continent level. These distinct lineages diverged from Chinese counterparts during the Pleistocene epoch when land bridges connected both regions. Polymorphism pattern within each lineage indicated that the diversity was shaped by differences in life history and selective
pressure. These findings establish the budding yeast harbors rich diversities that provide insights into its natural history.Keywords: population genomics, Saccharomyces cerevisiae, microbial ecology, amplicon sequence
應用於衛星通訊之高增益超寬頻圓形極化號角狀天線
為了解決ap-2318p 的問題，作者梁家誠 這樣論述：
低軌道衛星(Low Earth Orbit)通訊具有低延遲、高覆蓋率、高資料傳輸量，是未來通訊產業非常重要的一部分。其中高增益與圓形極化的天線特性是必要的條件。故本論文的研究目標在於，如何設計一超寬頻及高增益之圓形極化天線。該天線由四個高增益寬頻韋瓦第天線(Vivaldi antenna)以及超寬頻90度耦合電路(90°Hybrid coupler)所組成，除此之外，本論文提出一種從水平至垂直接面之微帶線訊號轉換。最後進行實作並進行量測，其阻抗匹配頻寬為12至40 GHz，涵蓋Ku、K、Ka頻段，在全頻段內天線軸比皆低於3 dB，天線增益可達到18.35 dBic。
