Eponyms are widely represented in technical, social and natural sciences. Electrocardiography terms, named after the researcher who first described them, have not been summarized in one place until now. Wellens syndrome (Henrick Joan Joost Wellens, Dutch cardiologist) refers to a subgroup of patients with unstable angina who are at risk of developing an anterior myocardial infarction. In 2008, the Dutch cardiologist Robert Jan de Winter described a unique electrocardiographic (ECG) finding for proximal left anterior descending artery occlusion, named de Winter's pattern.Smith-Sgarbossa criteria (Elena Sgarbossa, Stephen Smith) are used to recognize acute myocardial infarction in patients with left bundle branch block. Schamroth's sign (Abraham Leo Schamroth, South African cardiologist) is an indirect ECG finding that indicates chronic obstructive pulmonary disease. Wolff-Parkinson-White syndrome (WPW) was named after the doctors who in 1930. first described the syndrome of short PR interval and abnormal QRS complexes, associated with paroxysmal tachycardia (Louis Wolff, John Parkinson, Paul Dudley White). S1Q3T3 or McGinn-White sign (Sylvester McGinn and Paul White) was first described in 1935. as an ECG finding in support of acute pulmonary heart disease. Second degree AV blocks could be type Wenckebach (Karel Frederik Wenckebach, Dutch anatomist) or type Mobitz (Woldemar Mobitz, Russian-German physician). Ashman's phenomenon (Richard F. Ashman, American physiologist) is a simple ECG manifestation of conduction disturbances, caused by a change in frequency. Bix's rule (Harold Bix) is used to recognize supraventricular tachycardia. Brugada syndrome (Pedro and Josep Brugada) is a congenital channelopathy of sodium channels, with a high risk of sudden cardiac arrest. TP segment's down-sloping in the early stage of pericarditis is called Spodick's sign (David H. Spodick, American cardiologist).

In this fine collective biography of the merchants-turned-industrialists who developed the famed Waltham-Lowell system of textile manufacture, Robert F. Dalzell has produced a book of considerable importance in the history of American industrialization, entrepreneurship, and philanthropy. Dalzell presents a well-researched and lucid study of this wealthy, closely knit group of businessmen, a study that appropriately places these men and their activities in the broad sociocultural setting. The Boston Associates, according to Dalzell, were industrial pioneers who introduced integrated innovations on a hitherto unparalleled scale, but whose motivation was essentially conservative.

Timothy Tyson frames his prize-winning first book with two images. In 1936 an eleven-year old African-American boy in Monroe, North Carolina, witnessed a white police officer, Jesse Helms, Sr., physically assault a black woman and then drag her, dress up over her head, along the pavement to the local jail. White bystanders laughed. African American men hung their heads and hurried away. Sixty years later Robert F. Williams, that black boy who became an advocate of "armed self-reliance," was laid to rest, his body carefully dressed in a gray suit given him by Mao Zedong, his coffin adorned with a red, black, and green pan-African flag, and his eulogy given by Rosa Parks, the embodiment of non-violent resistance.

Full textAbstract:
Abstract Immune checkpoint inhibitors (ICI) were recently approved as a first-line treatment for inoperable esophageal adenocarcinomas (EAC) in combination with chemotherapy (CTX). Unfortunately, even though EAC has one of the highest tumor mutation burdens among all cancer types, response to immunochemotherapy (ICI+CTX) is highly variable, and the underlying molecular basis is incompletely understood. While genomic features such as mutations and copy number alterations in EAC are highly variable across samples, DNA methylation array data from numerous studies suggested that EAC can be clustered into a few consistent subtypes. We thus hypothesize that epigenetic heterogeneity of EAC may contribute to or associate with patients’ heterogeneous response to ICI+CTX, possibly through modulation of key genes or neoantigens. To test this hypothesis, we took advantage of a unique ICI+CTX LUD2015-005 trial in which inoperable EAC patients received first-line ICI for four weeks (ICI-4W), followed by ICI+CTX. Instead of methylation array, we also used a new DNA methylation sequencing technology, TET-Assisted Pyridine-Borane Sequencing (TAPS), on 64 tumor and 15 adjacent normal tissue samples collected from 23 EAC patients before and throughout treatment. Unlike prior studies that used methylation arrays which only cover ~2.5% of all CpG sites in the genome, TAPS detects genome-wide, base-resolution DNA methylation information. Furthermore, many previous studies did not account for variability in tumor content between samples, which could impact downstream DNA methylation analyses. In view of this, we proposed an analytical framework that includes tumor content and local copy number as key parameters, which estimates the tumor and stromal methylation and tests for differentially methylated regions (DMR). We also performed unsupervised clustering based on large scale genome-wide methylation pattern and revealed 2 major tumor clusters. Using the whole genome data, we identified a large set of shared tumor-specific DMRs, revealing that hypomethylation across wide regions of the genome and hypermethylation of certain gene bodies are common features in EAC. We also identified a set of shared outcome-associated DMRs in pre-treatment samples, which predicts better progression-free survival at 12 months. We further performed subgroup analysis of the 2 tumor clusters. Interestingly, we found higher numbers of cluster-specific prognostic DMRs with stronger effect sizes. This suggests that tumor subtypes may respond differently to treatment, and should be considered separately in statistical analyses. Altogether, these results indicate that a detailed understanding of tumor epigenetic heterogeneity will improve patient stratification in immunochemotherapy. Citation Format: Phil F.

Abstract The discovery of innovative cancer prevention and treatment approaches relies on voluntary participation in clinical trials (CTs); however, participation remains low among minorities/ethnic groups. Knowledge of CTs has been reported as a barrier to CT participation. Yet, there is limited understanding regarding CTs knowledge and participation among gastrointestinal (GI) cancer survivors in Puerto Rico (PR). Colorectal cancer is the second leading cause of death in PR, accounting for 13% among men and women. We aimed to describe the knowledge and factors associated with cancer-related CTs among Hispanic/Latino GI cancer survivors in PR. We analyzed preliminary data from an ongoing cross-sectional study targeting Hispanic/Latino GI cancer survivors aged 21+ years in PR. The study employed an interviewer-administered questionnaire to assess participants' awareness, knowledge, and participation in cancer-related CTs, and the social determinants of health (SDoH) associated with CT participation. Descriptive statistics were used to describe the population. Pearson chi-square test or Fisher's exact test were used accordingly to assess significance. A generalized linear model was used to estimate the odds ratios and 95% confidence intervals (CI) for significant variables. As of November 9, 2023, 59 Hispanic/Latino GI cancer survivors had completed the questionnaire. Women accounted for 56% of the sample, and the median age of study participants was 65 years (IQR: 19). Racial identity among participants was primarily white (63%), followed by other races (18%) and African-American (18%). Most participants were in complete or partial remission from cancer (83%). A significant proportion of the respondents reported having at least 12th grade (81%) and an annual income of $20,000 or higher (67%). Most participants (76%) accurately identified the correct definition of a CT. Participants with 12th grade or more had 1.5 (95% CI:1.1-1.9) times the possibility to correctly identify the CT definition compared to to those with less than 12th grade. Similarly, respondents with an annual income equal or higher than $20,000 had 1.4 (95% CI:1.1-1.8) times the possibility to correctly identify the CT definition compared to their counterpart. Furthermore, 93.2% of respondents had a score of at least 80% of correct responses regarding their knowledge of CTs. Although nearly 100% of the respondents knew about CTs, only 20% had participated. Despite a high level of knowledge regarding CTs in PR, a significant gap remains between knowledge and participation. Factors such as education and income might play a role in understanding the CT definition. However, the barriers preventing participation, including SDoH need further exploration. Enhancing participation among Hispanic/Latino GI cancer survivors in PR is essential for advancing cancer research and improving outcomes for this at-risk population.

Full textAbstract:
Abstract INTRODUCTION: Clonal hematopoiesis of indeterminate potential (CHIP) is defined by the expansion of progeny derived from hematopoietic stem cells that have acquired somatic mutations at a VAF greater than 2%. CHIP manifests in 10% of patients older than 65 and is associated with an increased risk of progression to malignancies such as the MDS or AML. Although the risk factors for developing CHIP remain incompletely defined, they include prior exposure to chemotherapy and a history of smoking. Monoclonal gammopathy of undetermined significance (MGUS) is characterized by the abnormal growth of clonal plasma cells in the bone marrow and carries a risk of 1% for progression to multiple myeloma (MM) per year. Like CHIP, it becomes more prevalent with age and is associated with smoking. Additionally, patients with MM have demonstrated an increased risk for malignancies. Thus, an examination for a correlation between CHIP and MGUS promises to reveal a link between these two pre-malignant conditions. A recent study did not demonstrate such an association, but this study was performed in a very elderly population and may not be applicable to younger patients. In this study, we aim to assess the relationship between CHIP and MGUS in a population-based cohort of MGUS patients seen at UT Southwestern Medical Center. METHODS: To evaluate an association between CHIP and MGUS, we collected bone marrow samples from 37 patients diagnosed with MGUS. We employed a hybridization capture-based next generation sequencing assay in order to detect CHIP. We identified 24 genes known to cause CHIP in adults. We also evaluated patients risk for developing MM after having been diagnosed with CHIP. RESULTS: The mean age was 68, (range 26-92). 22 patients were white, 8 were black and 3 Hispanic/Latino. 17 patients had IgG, 7 had IgA, 3 had IgM, 3 had biclonal gammopathy and 7 light-chain MGUS. We identified 18 mutations to validate the presence of CHIP in 10 (27%) patients, with the most frequent being DNMT3A (7 patients) and TET2 (5 patients). Other common mutations noted were PPM1D (2), GND1 (1), SF3B1 (1), ASXL1 in (1), and NRAS in (1). 3 out of the 10 patients harbored 2 mutations and 1 harbored 4 mutations. History of chemotherapy (n=6) and smoking (n=14) was taken into consideration to determine the relative risk of patients with MGUS developing CHIP. We found that those who had a prior history of smoking and chemotherapy displayed a higher risk of CHIP. CONCLUSION: There was no significant association between CHIP and MM progression. Our analysis showed 1 patient with CHIP progression and 2 without CHIP progression. Because the rates of CHIP and MGUS are positively correlated with characteristics like aging and a history of smoking, we expected to see high rates of CHIP in patients within our cohort. However, our data suggests that CHIP is frequent (27%) in MGUS patients, but larger future cohorts need to be evaluated to validate this association.

Waging war in Afghanistan and Iraq, U.S. Secretary of Defense Robert M. Gates rarely got a chance to relive the lighter days of his youth. One such moment came on July 28, 2010—a day of celebration at Fort A.P. Hill in Virginia. The year marked the one-hundredth birthday of the Boy Scouts of America (BSA), and Gates’s keynote address set the tone for a big patriotic show featuring flags, paratroopers, antiaircraft cannons firing blank shots, and a flyover of F-16 jets. Despite the jubilant occasion, the Pentagon chief had not come to spin campfire yarn. Amid the cheers of almost fifty thousand Scouts gathered at the army installation, Gates, an Eagle Scout from 1958, reaffirmed the movement’s intergenerational contract that promised a relationship of mutual allegiance between boys and men. “I believe that today, as for the past 100 years, there is no finer program for preparing American boys for citizenship and leadership than the Boy Scouts of America.” Reciting the themes of crisis, anxiety, and salvation that supporters of the nation’s foremost youth organization had evoked since its founding, Gates extolled scouting as the best remedy for an America “where the young are increasingly physically unfit and society as a whole languishes in ignoble moral ease.” While many youths had degenerated into “couch potatoes,” the BSA continued to make men and leaders, men of “integrity and decency … moral courage” and “strong character—the kind of person who built this country and made it into the greatest democracy and the greatest economic powerhouse in the history of the world.” More was at stake than the fate of the nation. “The future of the world itself,” said Gates, depended on the “kind of citizens our young people” would become. Only with the ...

Abstract On January 20, 1993, Hillary Rodham Clinton moved into the White House amid predictions that she would completely rewrite the job of First Lady. Headlines described a president’s”First Partner" who is”breaking new ground." One magazine searched the record of three administrations to fashion a composite that did her justice, finally concluding that she was a”presidential super spouse" who combined”the policy presence of an Eleanor Roosevelt [with] the sounding board of a Milton Eisenhower and the ... generalship on hard decisions that Robert F. Kennedy offered during the Cuban missile crisis of 1962." Within months, a popular magazine outlined not”The President’s First One Hundred Days" but”A Hundred Days of Hillary." The normally sedate Atlantic suggested that she was making”motherhood look good" on women’s job resumes, and the career-minded Working Woman evaluated the”ripple effect of the’Biliary’ phenomenon" on”husband-wife business relationships" across the nation." Television viewers of CNN’s popular”Sonya Live" cheerfully offered their own opinions of the First Lady’s effect on the president and on the nation.

This chapter continues to detail the history of the social justice–focused Cambridge movement and white politicos’ use of laissez-faire gradualism to thwart it. It discusses Richardson’s growing influence in the Cambridge movement, particularly her ideas about who should be involved in the movement, what its goals should be, and what strategies and tactics should be used to achieve them. She rejected the politics of respectability, which stressed adherence to certain dress and personal behavior standards, and presented herself to white leaders, including Attorney General Robert F. Kennedy, as an unflinching advocate for black liberation. This chapter also covers Richardson’s role in the “Treaty of Cambridge,” a formal agreement between city leaders and CNAC that outlined the steps white leaders would take to address the city’s racial issues.

Abstract Chapter Seven studies the growing radicalization of Black protest, and the concomitant stiffening of white resistance, in the wake of the passage of the Civil Rights Act of 1964. The Act empowered Black activists to broaden their campaign of sit-ins and boycotts around the city, in the hopes of ending segregation practices rendered illegal by the Act. These renewed protests, however, in turn sparked violent efforts by the Ku Klux Klan and white citizens to maintain segregation, regardless of federal legislation. This chapter also illuminates Black efforts to engage the Klan in a gun battle, the ongoing legal efforts intended to force local eateries to serve Black customers, and the eventual intervention of US Attorney General Robert F. Kennedy.

Especially among poor minorities, he had a particular magnetism – at once shy, boyish, and tough. As part of his own evolution, he found himself most comfortable in black inner cities, on Indian reservations, or among striking Chicano workers. Yet the former Attorney General also preached “law-and-order,” winning cheers from white working class audiences. His assassination in the immediate aftermath of his California primary victory stained an already-marred year, with deep effects on the electorate’s moods and the candidates’ fortunes.

Abstract The Kennedy White House focused on Cuba within a week of taking office. Two days after the inauguration, the chair of the Joint Chiefs of Staff, General Lyman Lemnitzer, arrived at the State Department with a packet of measures aimed at overthrowing Castro, which he presented in a meeting of several advisers, including Dulles, Rusk, McNamara, Undersecretary of State Chester Bowles, and Attorney General Robert F. Kennedy. No one discussed a plan of action, except that Rusk mentioned the possibility of landing the exiles on the Isle of Pines below Havana. His colleagues, however, added a new twist to the proposal by emphasizing the necessity of direct U.S. military support.

This chapter looks at the continuing centrality of race to understandings of the southern way of life from the end of World War II to the mid-1960s. Seminal events included the Supreme Court’s Brown v. Board of Education decision that mandated the desegregation of public schools and the conservative reaction to it symbolized by the White Citizens’ Council, the rebirth of the Lost Cause, and the murder of Emmett Till. The Montgomery Bus Boycott launched an activist civil rights movement, and the chapter examines the role of Martin Luther King Jr. and Robert F. Williams in articulating competing non-violent and self-defense strategies. The chapter covers a range of approaches by politicians from Massive Resistance to desegregation to the efforts of moderate white leaders to reform but keep the segregationist structure of southern life. The sit-ins in the early 1960s were important to a slowly evolving regional consciousness. The end of legal segregation and disfranchisement were landmarks in the transformation of southern society.

Under orders from President John F. Kennedy and Attorney General Robert F. Kennedy, the Internal Revenue Service (IRS) and the Federal Communications Commission (FCC) tightened the regulatory screws on conservative broadcasters. The IRS launched the “Ideological Organizations Project” to challenge the tax-exempt status of conservative broadcasters and to stem the flow of donations. The FCC strengthened its “Fairness Doctrine” rules, which required radio stations to ensure politically balanced discussion of public policy and to give free response time to victims of personal attacks made on the air. The United Auto Workers financed the creation of an opposition research clearing house, Group Research Inc., that compiled dossiers of damaging information on conservative broadcasters and politicians. The White House also organized a front organization, the Citizens Committee for a Nuclear Test Ban, to gain free, pro-administration airtime from radio stations that aired conservative critiques of the proposed treaty.

This chapter argues that the key to the theory and practice of the Black Panther Party (BPP) during its early years was an understanding of urban black neighborhoods as colonized spaces that needed to be liberated before African Americans could truly be free. Drawing from Frantz Fanon, Mao Zedong, Che Guevara, and pioneering black internationalists such as Malcolm X and Robert F. Williams, the Panthers embraced a form of revolutionary nationalism that posited the dire conditions facing black Oaklanders as part of a worldwide system of oppression linked to capitalism and white supremacy. In doing so, the BPP's founders built directly on their experiences with other organizations, particularly the Revolutionary Action Movement (RAM), as well as lessons drawn from the daily lives of people of color in the Bay Area.

Full textAbstract:
The presented research addresses the development, implementation and evaluation of helicopter flight control laws based on Incremental Dynamic Inversion (IDI). IDI is a promising control approach for manned helicopter applications as it is inherently robust against modeling errors, hence alleviating the need for highly accurate dynamics models usually required for decoupling controllers. The discussed controller is designed for the DLR's ACT/FHS research helicopter and was tested in its associated high-fidelity flight simulator AVES. The ACT/FHS is a modified EC135 helicopter equipped with a fly-by-wire/fly-by-light control system with full authority. While most research on IDI focuses on nonlinear control, the presented controller demonstrated good control ability over the full flight envelope utilizing only linear models of the ACT/FHS. To overcome actuator rate saturation, different methods were evaluated. The final flight controller was assessed in simulator test trials for its tracking performance and flight characteristics. In direct comparison with a currently used model-based flight controller of the DLR, IDI achieved significantly higher robustness against modeling errors and similar reference tracking performance. Furthermore, in conclusive pilot tests the Handling Qualities (HQ) for the Mission Task Elements Pirouette and Slalom according to ADS-33E (Ref. 1) were assessed. The controller achieved HQ ratings between Level 1 and Level 2.

Full textAbstract:
Harold F. Pitcairn, American aviation and Autogiro pioneer, died from a single gunshot wound to the head in the late evening hours of April 23, 1960 at the age of 62 after a gala evening at which he presided over a celebration attended by more than 450 guests for his brother's Raymond's 75th birthday. Initially labelled a suicide by the press, Pitcairn's widow Clara declared that "she never wanted to hear another word about the tragedy", while friends and friendly local authorities made the argument, duly reported by Frank Kingston Smith in Legacy of Wings, his devotional Pitcairn biography (subsidized by the Pitcairn family), that the death was accidental because "there was no note, no indication of depression or unhappiness" and "the police investigation disclosed that two shots had been fired; one had penetrated the ceiling directly over the desk in the first floor study, another had struck Pitcairn in the eye" and that "the next morning it was discovered the semi-automatic pistol was defective: when cocked, it had a supersensitive "hair trigger," and it had a faulty disconnector so that it would fire more than one shot at a time, a condition known as "doubling."" The Pitcairn families, prominent and powerful, prevailed upon the local authorities to declare the death accidental and Kingston Smith's 1981account became the de facto authoritative story of the death of Harold F. Pitcairn. With the perspective, however, of six decades, it appears far more likely that Pitcairn's death was a suicide for reasons that were not readily evident, minimized, unappreciated or deliberately ignored at the time to craft a result that met the needs of Clara Pitcairn and her surviving family. These included the fact that while the claim was made that Pitcairn was making his nightly rounds to check on the estate’s ground-level windows (and had been doing so since the Lindbergh kidnapping in 1932), he actually died at his desk; that those in the house only reported a single shot; the 1907 Savage pistol had no reputation for a hair-trigger, and had not evidenced such a flaw in almost three decades of Pitcairn's nightly ritual; that even though Pitcairn had been assured that his almost-decade-long lawsuit against the United States government for Patent infringement of his Autogiro patents was going well, he was concerned about the impact this lawsuit was having on his aged associates who had been called to give depositions and he had voiced the sentiment that "if he had known that he would have to sue the government, he would not have gone into the Autogiro business"; that the lawsuit, itself intended as a vindication of Pitcairn's contribution to aviation was dragging on and would reach its first legal conclusion in 1967, and not finally conclude upon appeal until 1977; and most importantly, those who deny suicide and point to Pitcairn’s state-of-mind, have failed to take into account when the death occurred or ready evidence of his 'state of mind' To fail to see the tragic end of Harold F. Pitcairn is to forget that 29 years and one day earlier, he had been recognized for "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." The memory of that day on the White House back lawn with the President was the high point of his life even as Pitcairn prepared to celebrate his older brother's achievements. The evidence, when marshalled and documented, conclusively points to suicide - a death of an American aviation pioneer before his contributions were vindicated in the largest patent infringement judgement against the United States in history. To fail to see the tragic end of Harold F. Pitcairn is to forget that 29 years earlier, he had been recognized for "the greatest achievement in aeronautics or astronautics in America".

Full textAbstract:
With the recent renewed interest in higher speed passenger rail (“HrSR”) in North America, there will be increased pressure on freight railroads to collaborate with public transportation agencies in the establishment of “shared use” tracks. Track infrastructure in these corridors must be robust enough to support the heavy axle loading associated with conventional North American freight traffic while accommodating FRA Class 6-7 passenger operating speeds in excess of 100 mph. Turnouts which permit higher diverging route speeds will become increasingly important as service-sensitive passenger operations look to reduce transit times and freights grapple with capacity concerns. Innovative approaches to the design, manufacture and construction of turnouts are called for. Critical design elements for a new generation of “shared use” turnouts will include: a) Tangential and compound geometries to optimize ride quality and safety; b) Respecting the spatial constraints of existing infrastructure (opposing signal locations) while maximizing diverging route permissible speeds; c) Kinematic gauge optimization through switches to enhance ride quality and increase component life; d) Premium frog designs to minimize running surface discontinuities; e) Cross tie housed rodding and position detection systems to facilitate continuous maintenance surfacing; f) Integrated switch drive, detection and monitoring systems to facilitate proactive intervention by maintenance forces.

Abstract Among the list of advanced technologies required to support the energy industry’s novel Supercritical Carbon Dioxide (sCO2) power cycle is the need for a robust and responsive control system. Recent testing has been performed on a 2.5 MWe sCO2 compressor operating near the critical temperature (31C) and critical pressure (73.8 bar), developed with funding from the US DOE Apollo program and industry partners. While sCO2 compression has been performed before, operating near the critical point has many key benefits for power generation with its low head requirements and smaller physical footprint. However, with these benefits come unique challenges, namely controlling this system to steady-state operating conditions. Operating just above the critical point (35°C [95°F] and 8.5 MPa [1,233 psi]) there can be large and rapid swings in density produced by subtle changes in temperature, leading to increased difficulty in maintaining adequate control of the compressor system. This means that proper functionality of the entire compressor system, and its usefulness to a closed loop recompression Brayton power cycle, is largely dependent on variables such as thermal sources, precision and response time of the instrumentation, proper heat soaking, and strategic filling and venting sequences. While other papers have discussed the science behind and performance of sCO2 compressors, this paper will discuss the challenges associated with steady-state control of the compressor at or near operating conditions, how the fill process was executed for optimal startup, and changes that occurred while idling during trip events.

Full textAbstract:
The extended loss of AC power (ELAP) event can pose a significant challenge to the integrity of the Reactor Coolant System (RCS) in a Pressurized Water Reactor (PWR). To mitigate the consequences of this event, it is important to maintain adequate coolant inventory and the associated heat removal capability of the RCS. A critical RCS component in maintaining RCS inventory is the Reactor Coolant Pump (RCP) seals. To ensure seal integrity, the RCP seals are either independently cooled by back-up systems or are sufficiently robust to maintain their integrity without cooling until such time when cooling may be restored. A number of new RCP seal designs have been proposed by seal manufacturers to meet this challenge. This paper focuses on one such design, namely, the KSB Station Blackout (SBO) seal package. KSB RCP seals were first introduced in the nuclear industry in the 1970s. The original KSB RCP seals, designated as HDD-254 Type A, consisted of a three stage hydrodynamic design with each stage capable of retaining full RCS pressure. The Type A seals were initially installed in the Combustion Engineering (CE) Palo Verde units and in several reactors in Germany. In the 1980s, these seals were replaced with the Type C seals that incorporated several design improvements. These seals have been successfully installed and operated in over 100 RCPs in Europe, South America, South Korea, and China. These seals continue to demonstrate excellent operating experience with typical replacement interval of 4 to 6 years. Although the reliability of the Type C seals has been excellent based on operating experience, the seal was not specifically designed for coping with an ELAP event that might ensue following an SBO. In order to support the emerging needs of nuclear industry in response to Fukushima, KSB embarked on a seal design improvement program directed towards retaining the high operational reliability of the Type C seal while enhancing the RCP seal package’s high temperature coping capability. This activity resulted in a new seal package design that includes: (1) an advanced high temperature resistant, three stage, Type F seal, (2) a passive thermal check valve (PTCV) intended to passively isolate the RCP controlled bleed-off (CBO) line to maintain RCS inventory, and (3) a back-up fourth stage shaft seal called the “Stand-still” seal. This paper discusses the design and post-accident performance of KSB’s Type F hydrodynamic RCP seal package with emphasis on seal performance capabilities under ELAP conditions. The report concludes that the capability of the primary three stage hydrodynamic seals and the fourth stage “Stand-still” seal to function at high temperatures coupled with the reliable RCP CBO line closure capability and subsequent RCS depressurization ensures that any potential seal leakage would be held to a minimum (less than 2 gpm) for the duration of a 72 hour ELAP scenario. The ELAP coping strategies and their outcomes were validated by a seal test program conducted at KSB’s testing laboratories in Frankenthal, Germany. The results of the tests confirmed that the Type F seals exhibited extremely low leakage rates (∼0.01 gpm) at conditions representative of an ELAP scenario (120 hours up to 300 °C [572 °F] temperature and 160 barg [2320 psig] pressure).

IntroductionDigital assistant systems (DAS) can support tasks by mediating between complex data and users, promoting continuous learning and on-the-job training (Jwo et al., 2021; Longo et al., 2017; Prinz et al., 2017). Integrating a DAS into surgical instrument reprocessing, where instrument-specific and complex manual tasks need to be performed strictly according to the manufacturer's instructions, can be advantageous. In Germany, reprocessing by trained on-the-job personnel is common. In addition, human factors are often neglected in the instructions for instrument reprocessing (Choi et al., 2017). A cooperative robot can be a valuable addition to mitigate health risks associated with handling contaminated surgical instruments during reprocessing, resulting in a cyber-physical assistance system (Heibeyn et al., 2021). However, it is unclear how the transition from paper-based instructions to either a DAS or a DAS supplemented with a cooperative robot assistance (“cyber-physical assistance system” – CPAS) affects usability for complex and workpiece-specific tasks in instrument reprocessing. Therefore, this study aimed to investigate the differences in usability with different assistance systems for typical tasks in instrument reprocessing for untrained personnel.MethodsWe conducted an interaction-centered user study with 13 participants unfamiliar with the reprocessing tasks. The participants were asked to complete typical reprocessing tasks three times in a random order, using different assistance approaches each time. The reference process consisted of paper-based instructions that required stepping away from the workstation to retrieve information from the storage of guidelines, simulating common set-ups of current reprocessing processes. The first assistance approach presented digital instructions right at the workstation. The second assistant combined a cooperative robot with digital instructions. The robot performed simple processing steps, while the human operator focused on the complex tasks and verified the cleaning success. We measured the required time, counted user errors and rated the criticality, measured the perceived workload using the NASA-TLX questionnaire (NASA, 2020), and documented the remarks of the participants using the thinking-out-loud method for all assistance systems.Results The NASA-TLX did not reveal any significant differences among the three systems, however, the CPAS reduced the number of critical errors. The errors included omitted processing steps and deviations from required times, which could pose risks to patients. The DAS was perceived as a suitable way to check instructions, based on the participants’ comments. However, in the case of the CPAS, some participants missed or ignored messages provided by the user interface.Discussion and ConclusionIn summary, the CPAS improved usability the most, improving effectiveness (number of errors) while maintaining the same efficiency (total duration). Although our study found promising results for integrating a DAS or CPAS into on-the-job training assistance for novice personnel, future studies should compare the results obtained from inexperienced to those of experienced users to fully assess the usability of related approaches. This study contributes to the field of human factors by providing comparative data on usability across different levels of assistance for complex and workpiece-specific tasks in surgical instrument reprocessing.ReferencesChoi, J., Seraphina, S., & Knudsen, K.
