Arthur Frommer’’s Europe

為了解決twice的問題，作者Frommer, Arthur,Ames, Paul,Barron, Peter 這樣論述：

Arthur Frommer The son of a Polish-born mother and an Austrian-born father, Frommer was drafted into the U.S. Army during the Korean War, but was stationed in Europe because of his fluency in German and Russian. During his service, he wrote and self-published a guidebook called The GI’s Guide to Tra

veling in Europe in 1955 that was an immediate hit among his fellow soldiers. In 1957, Frommer created a civilian version called Europe on 5 Dollars a Day, which became an overnight best seller. He subsequently published guidebooks covering all parts of the globe. Frommer licensed his travel guide b

ook business to Simon & Schuster in 1977. Eventually, the Frommer’s series was purchased by John Wiley & Sons, and in August 2012, Google purchased the travel guides. Through all the exchanges, Arthur Frommer was always deeply involved with the guide books. In 2013, Frommer reacquired control of the

guidebooks bearing his name and has come full circle, now self-publishing his iconic travel books again. Additionally, Arthur Frommer writes a travel column syndicated through King Features, and co-hosts a weekly syndicated radio show with his daughter Pauline, ＂The Travel Show with Arthur & Paulin

e Frommer.＂ Arthur resides in New York City. Paul Ames (author Portugal): A native of England’s East Anglia region, Ames has been fascinated by Portugal since a childhood visit in the 1970s when the country was gripped by revolutionary fervor. After 20 years based in Brussels covering Europe for Th

e Associated Press and other international media, he returned to Lisbon in 2013. Paul works as a freelance journalist and never tires of exploring the delights of his adopted homeland, from the green hills of the Minho to sub-tropical Madeira island and all the beaches in between. Peter Barron (auth

or Spain): After careers at the BBC and Google, Peter Barron turned his attention to restoring a barn with his wife Julia at their finca on the border between Andalucía and Extremadura. He has been visiting Spain for over thirty years and loves flamenco guitar, ibérico ham, and manzanilla sherry. He

is one of the authors of Frommer’s Spain and blogs about Extremaduran life at adventuresinextremadura.com. He divides his time between Spain and London. Anna E. Brooke (author France) relocated from her native Britain to Paris in 2000 and hasn’t looked back since. She is now a full-fledged bohemian

, juggling life between freelance travel writing (Frommer’s, Sunday New York Times Travel, Time Out Paris and the Financial Times), children’s fiction, acting and songwriting for film. Jennifer Ceaser (author Belgium and The Netherlands) is a freelance writer and editor who has specialized in travel

journalism for two decades. A former New Yorker and staff editor at the New York Post, Jennifer has lived in Europe since 2016, including Amsterdam, Berlin and Barcelona. She contributes to a variety of publications including Condé Nast Traveler, AFAR, New York magazine, BBC, Time Out, Delta Sky, a

nd Wine Enthusiast. Jason Cochran (author, England & Scotland) was twice awarded Guide Book of the Year by the Lowell Thomas Awards (Society of American Travel Writers) and once by the North American Travel Journalists Association for his book Frommer’s EasyGuide to London. His writing has appeared

in the New York Post, Entertainment Weekly, Travel + Leisure, USA Today, and Budget Travel , among many others. Jason has appeared as a host and commentator on CBS, Fox and AOL, to name a few. He currently is the Editor in Chief of Frommers.com. Donald Strachan (author Italy) is a writer and journal

ist who has written about Italy for publications worldwide, including National Geographic, the Guardian, Sunday Telegraph, and the Independent. Rachel Glassberg (author Austria, Germany, Switzerland) is a Berlin-based journalist last seen traversing the Alps for Frommer’s Switzerland and ruining he

r friends’ favorite bars for Frommer’s Germany. Formerly deputy editor of the English-language city magazine Exberliner, she now divides her time between writing, music, and travel -- sometimes two or even all three of those simultaneously.

運動訓練與停止訓練對中老年人骨骼肌氧合能力與身體功能表現之影響

為了解決twice的問題，作者杨永 這樣論述：

運動是一種改善中老年人骨骼肌氧合能力、提高肌肉力量並最終影響整體身體功能表現的有效方式。然而，較少的研究評估不同運動類型之間訓練效益的差異。此外，由於中老年人生病、外出旅行與照顧兒童等原因，迫使運動鍛煉的中斷。如何合理安排運動訓練的週期、強度與停訓週期，以促使中老年人在未來再訓練快速恢復以往訓練效益，目前亦尚不清楚。本文以三個研究建構而成。研究I：不同運動訓練模式對中老年人的骨骼肌氧合能力、肌力與身體功能表現的影響。以此探討50歲及以上中老年人進行每週2次為期8週的爆發力、阻力訓練以及心肺訓練在改善中老年人肌肉組織氧合能力、與肌肉力量身體功能效益的差異。我們的研究結果表明：爆發力組在改善下肢

肌力、最大爆發力與肌肉品質方面表現出較佳的效果。心肺組提高了30s坐站測試成績並減少了肌肉耗氧量，從而改善了中老年人在30s坐站測試期間的運動經濟性。年紀較高的肌力組則對於改善平衡能力更加有效。此外，三組運動形式均有效改善了中老年人人敏捷性。研究 Ⅱ：停止訓練對運動訓練後中老年人肌力與身體功能表現的影響：系統性回顧與meta分析。本研究欲探討停止訓練對運動訓練後中老年人肌力與身體功能表現訓練效益維持的影響。我們的研究結果表明：訓練期大於停止運動訓練期是肌力維持的重要因素。若訓練期

調控高分子給體二維共軛側鏈與設計共軛中心核與pi-架橋小分子受體結構與性質之系統性研究

為了解決twice的問題，作者陳重豪 這樣論述：

此研究中，我們通過引入具有（苯並二噻吩）-（噻吩）（噻吩）-四氫苯並惡二唑（BDTTBO）主鏈的新型供體-受體（D/A）共軛聚合物製備了用於有機光伏（OPV）的三元共混物。在BDTTBO單體中BDT供體單元上修飾不同的共軛側鏈聯噻吩 (BT)、苯並噻吩 (BzT) 和噻吩並噻吩 (TT)（記為 BDTTBO-BT、BDTTBO-BzT 和 BDTTBO-TT）。然後，我們將 BDTTBO-BT 或 BDTTBO-BzT 或 BDTTBO-TT 與聚（苯並二噻吩-氟噻吩並噻吩）（PTB7-TH）結合起來，以擴大太陽光譜的吸收並調整活性層中 PTB7-TH 和富勒烯的分子堆積，從而增加短路電流密

度。我們發現參入10%的BDTTBO-BT高分子以形成 PTB7-TH：BDTTBO-BT：PC71BM 形成三元共混物元件活性層可以將太陽能元件的功率轉換效率從 PTB7-TH 的二元共混物元件 9.0% 提高到 10.4%： PC71BM 轉換效率相對增長超過 15%。於第二部分，我們比較在BDTTBO單體中BDT供體單元上修飾硫原子或氯原子 取代和同時修飾硫原子和氯原子取代的側鏈聚合物供體與小分子受體光伏的功率轉換效率 (PCE) 的實驗結果與由監督產生的預測 PCE。使用隨機森林算法的機器學習 (ML) 模型。我們發現 ML 可以解釋原子變化的聚合物側鏈結構中的結構差異，因此對二元共混

系統中的 PCE 趨勢給出了合理的預測，提供了系統中的形態差異，例如分子堆積和取向被最小化。因此，活性層中分子取向和堆積導致的結構差異顯著影響 PCE 的預測值和實驗值之間的差異。我們通過改變其原始聚合物聚[苯並二噻吩-噻吩-苯並惡二唑] (PBDTTBO) 的側鏈結構合成了三種新的聚合物供體。同時修飾硫原子和氯原子取代的側鏈結構用於改變聚合物供體的相對取向和表面能，從而改變活性層的形態。 BDTSCl-TBO:IT-4F 器件的最高功率轉換效率 (PCE) 為 11.7%，與使用基於隨機森林算法的機器學習預測的 11.8% 的 PCE 一致。這項研究不僅提供了對新聚合物供體光伏性能的深入了解

，而且還提出了未明確納入機器學習算法的形態（堆積取向和表面能）的可能影響。於第三部分，為了理解下一代材料化學結構的設計規則提高有機光伏（OPV）性能。特別是在小分子受體的化學結構不僅決定了其互補光吸收的程度，還決定了與聚合物供體結合時本體異質結 (BHJ) 活性層的形態。通過正確選擇受體實現優化的OPV 元件性能。在本研究中，我們選擇了四種具有不同共軛核心的小分子受體——稠環核心茚二噻吩、二噻吩並茚並茚二噻吩（IDTT）、具有氧烷基-苯基取代的IDTT稠環核心、二噻吩並噻吩-吡咯並苯並噻二唑結構相同的端基，標記為 ID-4Cl、IT-4Cl、m-ITIC-OR-4Cl 和 Y7，與寬能帶高分子

PTQ10 形成二共混物元件。我們發現基於 Y7 受體的器件在所有二元混合物器件中表現出最好的光伏性能，功率轉換效率 (PCE) 達到 14.5%，與具有 10.0% 的 PCE 的 ID-4Cl 受體相比，可以提高 45%主要歸因於短路電流密度 (JSC) 和填充因子 (FF) 的增強，這是由於熔環核心區域中共軛和對稱梯型的增加，提供了更廣泛的光吸收，誘導面朝向並減小域尺寸。該研究揭示了核心結構單元在影響有源層形態和器件性能方面的重要性，並為設計新材料和優化器件提供了指導，這將有助於有機光伏技術的發展。最後，我們比較了具有 AD-A´-DA 結構的合成小分子受體——其中 A、A´ 和 D 分

別代表端基、核心和 π 價橋單元—它們與有機光伏聚合物 PM6 形成二共混物元件。 增加核苝四羧酸二亞胺 (PDI) 單元的數量並將它們與噻吩並噻吩 (TT) 或二噻吩吡咯 (DTP) π 橋單元共軛增強了分子內電荷轉移 (ICT) 並增加了有效共軛，從而改善了光吸收和分子包裝。 hPDI-DTP-IC2F的吸收係數具有最高值（8 X 104 cm-1），因為它具有最大程度的 ICT，遠大於 PDI-TT-IC2F、hPDI-TT-IC2F和 PDI-DTP-IC2F。 PM6:hPDI-DTP-IC2F 器件提供了 11.6% 的最高功率轉換效率 (PCE)；該值是 PM6:PDI-DTP-

IC2F (4.8%) 設備的兩倍多。從一個 PDI 核心到兩個 PDI 核心案例的器件 PCE 的大幅增加可歸因於兩個 PDI 核心案例具有 (i) 更強的 ICT，(ii) 正面分子堆積，提供更高的和更平衡的載波遷移率和 (iii) 比單 PDI 情況下的能量損失更小。因此，越來越多的 PDI 單元與適當的髮色團共軛以增強小分子受體中的 ICT 可以成為提高有機光伏效率的有效方法
