Chip War : The Fight for the World’s Most Critical Technology

為了解決Scarce的問題，作者 這樣論述：

你不可不知，全球當今最夯話題 關於中美晶片大戰的全面揭秘！   　　今日的晶片技術價值之高，可謂是當代「新石油」，一個全球都爭先搶後的稀缺資源！現代無論是軍事、經濟，甚至是各國的政治權力基礎，都可以說是建立在電腦晶片的基石上，這說法並不誇張，畢竟大至飛彈武器，小至家庭廚房必備的微波爐；從人手一機的智慧型手機，到掌握全球經濟命脈的股市市場，背後無一不靠晶片運作。目前美國尚還保有最強大、高速的晶片設計能力，足以讓其坐在晶片的龍頭寶位上，然而美國與各個競爭對手如台灣、南韓的距離卻越來越小，其中尤以中國最為虎視眈眈。本書中指出，近幾年來中國砸了數十億美元發展研究，為的就是要追趕上美國的腳步。此一

大舉動，自然危及了美國在全球的軍事和經濟體的優越地位。   　　經濟史學家克里斯．米勒，在本書中詳細記載了小小的半導體，是如何成為當代操控政治和經濟的重要因素，以及美國在一開始如何在晶片設計和製造取得先機，並將技術進一步發展至軍事上。另一方面，中國在晶片發展上的野心以及軍事的先進改革，又是如何追趕而上，與美國齊頭並進。美國曾讓晶片製程的關鍵部分脫離其掌控，這不僅導致全球晶片短缺，並讓最大競爭對手有機可乘。透過本書，讀者將更進一步了解如今貿易大戰中最重要的角色──晶片。(文/博客來編譯) 　　You may be surprised to learn that microchips are th

e new oil—the scarce resource on which the modern world depends. Today, military, economic, and geopolitical power are built on a foundation of computer chips. Virtually everything—from missiles to microwaves—runs on chips, including cars, smartphones, the stock market, even the electric grid. Until

recently, America designed and built the fastest chips and maintained its lead as the #1 superpower, but America’s edge is in danger of slipping, undermined by players in Taiwan, Korea, and Europe taking over manufacturing. Now, as Chip War reveals, China, which spends more on chips than any other

product, is pouring billions into a chip-building initiative to catch up to the US. At stake is America’s military superiority and economic prosperity. 　　Economic historian Chris Miller explains how the technology works and why it’s so important, recounting the fascinating events that led to the Un

ited States perfecting the chip design, and to America’s victory in the Cold War by using faster chips to render the Soviet Union’s arsenal of precision-guided weapons obsolete. But lately, America has let key components of the chip-building process slip out of its grasp, leading to a worldwide chip

shortage and a new war brewing with a superpower adversary that is desperate to bridge the gap. 　　Illuminating, timely, and fascinating, Chip War shows that, to make sense of the current state of politics, economics, and technology, we must first understand the vital role played by chips.

基於翻譯序列推薦模型於跨領域推薦系統之強化方法

為了解決Scarce的問題，作者王均捷 這樣論述：

若我們有足夠多的歷史資料，就可以用很多不同的方法去建立一個聰明的推薦系統。但在某些情況下，比如一個新的社交媒體平台或電商平台上線時，我們沒有足夠的使用者物品互動資料來建構出好的推薦系統。其中一個強化跨領域推薦（cross-domain recommendation）的解決方案，是藉由將「來源領域（資訊含量較多之領域）」的資料加入「目標領域（資訊量相對較少的領域）」來提升資訊量，然後對「目標領域」進行推薦。本論文採用圖形學習表示演算法，結合改良並善用翻譯序列推薦模型（Translation-based Recommendation，TransRec）的推薦優勢，特化模型訓練時採樣方法、改變翻譯

序列合併方法，並引入貝氏個人化推薦（Bayesian Personalized Ranking，BPR）中負採樣（negative sampling）的概念，訓練得到推薦系統任務導向之表示向量，藉此改善推薦結果。本研究旨在通過改良後的翻譯序列推薦模型「TransRecCross」來強化跨領域推薦效果。驗證本論文的新方法時，使用了 Amazon Review 系列資料集中的其中四個，並在論文最後比較了加入不同比例的來源領域資料後的推薦結果，以驗證本論文提出之方法的可靠程度。

Chip War: The Quest to Dominate the World’s Most Critical Technology

利用本土嗜酸性硫桿菌從晶片載板中進行銅生物浸出探討

為了解決Scarce的問題，作者林俊宇 這樣論述：

由於現代電子產業的蓬勃發展，讓生活更便利的同時，也造成了印刷電路板和晶片載板等電子廢棄物量的增加，而印刷電路板(Printed circuit board，縮寫PCB)和晶片載板為金屬回收提供了可觀的資源。不久的未來，從電子廢棄物中有效回收這些金屬將成為一個非常重要的問題。從傳統的濕法冶金和火法冶金中回收這些金屬的方法成本高，而且會造成環境汙染。生物浸出(Bioleaching)是將金屬從固體物質中提取到溶液中，該反應由某些微生物的代謝促進，而嗜酸菌如Acidithiobacillus ferrooxidans是細菌生物浸出中眾所周知的參與者。本研究中，我們使用多個溫度、轉速、培養基和添加金

屬螯合劑去測試嗜酸菌適合的生長環境，並使用嗜酸菌進行PCB對銅生物浸出的探討。除了使用從食品工業研究所(BCRC)獲得的細菌菌株外，同時也從重金屬汙染的工業廢水中分離出能夠在酸性環境(pH2.5)中生長的微生物(Acidithiobacillus sp. CK-W)。實驗結果顯示，Acidithiobacillus sp. CK-W在30℃、轉速165 rpm、9K培養基和添加金屬螯合劑的環境下有較好的生長狀況。在生物浸出實驗中，菌株CK-W在第10天時擁有最大的銅浸出率(82%)。本研究的後續展望，將可收集生物浸出後含有金屬的溶液，進一步探討使用微生物吸附金屬的特性，進行後續金屬回收的分析與

研究。
