Visualization of details down to ~150 μm has been reported for this device. A cadaveric femur was imaged on UHR CT at three radial locations within the field-of-view: 0 cm (isocenter), 9 cm from the isocenter, and 18 cm from the isocenter; we expect the non-stationary blurs to worsen with increasing radial displacement. Gray level cooccurrence (GLCM) and gray level run length (GLRLM) texture features were extracted from 237 trabecular regions of interest (ROIs, 5 cm diameter) placed at corresponding locations in the femoral head in scans obtained at the different shifts. We evaluated concordance correlation coefficient (CCC) between texture features at 0 cm (reference) and at 9 cm and 18 cm. We also investigated whether the spatially-variant blurs affect K-means clustering of trabecular bone ROIs based on their texture features.</p><p><strong>Results: </strong>The average CCCs (against the 0 cm reference) for GLCM and GLRM features were ~0.7 at 9 cm. At 18 cm, the average CCCs were reduced to ~0.17 for GLCM and ~0.26 for GLRM. The non-stationary blurs are incorporated in radiomic features of cancellous bone, leading to inconsistencies in clustering of trabecular ROIs between different radial locations: an intersection-over-union overlap of corresponding (most similar) clusters between 0 cm and 9 cm shift was >70%, but dropped to <60% for the majority of corresponding clusters between 0 cm and 18 cm shift.</p><p><strong>Conclusion: </strong>Non-stationary CT system blurs reduce inter-scan reproducibility of texture features of trabecular bone in UHR CT, especially for locations >15 cm from the isocenter. Radiomic models of bone quality derived from UHR CT measurements at isocenter might need to be revised before application in peripheral body sites such as the hips.</p>","PeriodicalId":45312,"journal":{"name":"PACIFIC HISTORICAL REVIEW","volume":"12 1","pages":""},"PeriodicalIF":2.7,"publicationDate":"2023-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10788132/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90415852","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Haddad’s eminently readable book traces what he calls a “seismic shift” in the decades between 1860 and 1900 as American Protestant missionaries sought to bring China to Christ (p. 3). Through twelve chapters of hair-raising stories of danger, hardship, and more than occasional pig-headedness, Haddad shows how missionaries shifted from preaching Christ to building hospitals, schools, and voluntary organizations that met Chinese needs and welcomed Chinese leadership. This shift in strategy, Haddad argues, was more than just a new hope for the Gospel in China. The evolving partnership between American Protestant missionaries and their Chinese Christian allies also created many enduring institutions that helped lay the foundations of modern China. Haddad tells this story through vivid memoirs and essays written by both Chinese and American missionaries. He demonstrates how early American attempts to browbeat local communities into the churches resulted in constant friction and very few converts. “After...

Despite Los Angeles County’s reputation for large public beaches, privatization and the discouragement of public use came to characterize Malibu’s Broad Beach by the end of the twentieth century. In the same era, erosion reshaped the boundary between public and private property on the beach. Residents called for permanent structures to stabilize the coast. Public beach activists rejected homeowners’ claims that beach armoring was in the public’s interest. Activists demanded state authorities expand access opportunities and protect public recreation instead of protecting beachfront mansions. As coastal erosion altered the parameters of public access, environmental change raised the stakes regarding state and federal authorities’ responsibilities to maintain beaches. At the turn of the twenty-first century, the longstanding challenge to public access in this exclusive Malibu enclave collided with the unfolding climate crisis, highlighting the entwined nature of environmental risk and real estate development on the beach.","PeriodicalId":45312,"journal":{"name":"PACIFIC HISTORICAL REVIEW","volume":"1 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"66922346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"历史学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It argues that U.S. western history and its adjacent fields can benefit from more sustained attention not only to particular religious practices and traditions, but also to the dynamics of religion-making or, in other words, to the social processes that configure “religion” and shape assumptions, both popular and scholarly, about where it can be found and how it operates.
