Damage Analysis and Startup Schedule Optimization of Steam Turbine Rotors With an Anisotropic Damage Coupled Viscoplastic Constitutive Model
Authors: Wang YuanLiang , Ni YongZhong , Liao YanQing , Xu Hong 
Published: March 2024

Abstract
The optimization of the operation scheme is of great significance for improving the flexibility of thermal power plants in energy systems dominated by renewable energy. However, thermal stress and corresponding thermomechanical fatigue damage are the main limitations. A unified viscoplastic constitutive model coupled with anisotropic damage is introduced and validated by comparing the experimental and simulated hysteresis loops and cyclic softening curves. The model is implemented into the ansys software by using the USERMAT subroutine to numerically investigate the high-temperature fatigue behavior of a 1000 MW steam turbine rotor on different startup schedules. The critical areas of the rotor are studied in terms of temperature, stress, accumulated inelastic strain, and damage. Based on the damage analysis, the hot start schedule is optimized and validated. The startup time can be significantly shortened within permitted fatigue damage. Moreover, the life expenditure under different loading-up rates is calculated and the extra startup costs can be evaluated accordingly for wider application.

Photovoltaic devices fabricated using mixed-cation halide perovskites have demonstrated a superior combination of high efficiency and long operating life. In this study, we synthesize a series of mixed-cation halide perovskites with the composition of MA1− xCs xPbBr3 (MA = CH3NH3), where x varies from 0 to 1. We carefully examine various polar solvents and develop a relatively facile, room temperature solution-based growth method for growing these single crystals under optimal conditions. We conduct a comprehensive investigation of the influence of the Cs+ cation on the structure and optical properties of the perovskite solid solutions. The structural characterization using X-ray diffraction confirms the successful substitution of cesium for the methylammonium (MA) cation in the MA1− xCs xPbBr3 perovskite structure, with a continuous solubility. As the Cs+ content increases, the crystal structure undergoes a gradual transformation from a cubic phase (for MAPbBr3) to an orthorhombic phase (for CsPbBr3). To study the impact of Cs substitution on their optical properties, we perform UV–Vis absorption analysis, and find no significant change in the bandgap value, which remains approximately 2.12–2.14 eV for the compositions with x up to 0.7. For x > 0.7, however, the bandgap value gradually increases to reach 2.21 eV for pure CsPbBr3. This work demonstrates a valid technique for the growth of halide perovskite solid solution crystals, which can be a versatile tool for tailoring the structure, long-term stability, and optoelectronic properties for advanced photovoltaic applications.
A Decentralized Private Data Marketplace using Blockchain and Secure Multi-Party Computation
Authors: Bernabé-Rodríguez Julen , Garreta Albert , Lage Oscar 
Published: March 2024

Big data has proven to be a very useful tool for companies and users, but companies with larger datasets have ended being more competitive than the others thanks to machine learning or artificial intelligence. Secure multi-party computation (SMPC) allows the smaller companies to jointly train arbitrary models on their private data while assuring privacy, and thus gives data owners the ability to perform what are currently known as federated learning algorithms. Besides, with a blockchain it is possible to coordinate and audit those computations in a decentralized way.
In this document, we consider a private data marketplace as a space where researchers and data owners meet to agree the use of private data for statistics or more complex model trainings. This document presents a candidate architecure for a private data marketplace by combining SMPC and a public, general-purpose blockchain. Such a marketplace is proposed as a smart contract deployed in the blockchain, while the privacy preserving computation is held by SMPC.
Characteristics of Carcinoembryonic Antigen-Related Cell Adhesion Molecules and Their Relationship to Cancer
Authors: Ma Ru-xue , Wei Jian-rui , Hu Yan-wei 
Published: March 2024

Abstract
Carcinoembryonic antigen-related cell adhesion molecules (CEACAM), such as carcinoembryonic antigen (CEA) and the oncofetal glycoprotein family, are tumor markers. The CEACAMs consist of 12 different human CEACAMs and 5 different murine CEACAMs. The CEACAM family of proteins participates in multiple biological processes that include the immune response, angiogenesis, and cancer. CEACAMs play a significant role in cancer initiation and development. Increasing evidence suggests that family members may be new cancer biomarkers and targets in that CEACEAMs tend to be aberrantly expressed and therefore may have potential diagnostic and therapeutic importance. This review systematically summarizes the biogenesis, biological properties, and functions of CEACAMs, with a focus on their relationship with cancer and potential clinical application. As our knowledge of the relationships among CEACAMs and cancer increases, and as our understanding of the involved molecular mechanisms improves, new therapeutic strategies will evolve for cancer prevention and treatment of patients with cancer.
A Tale of Two Laureates
Authors: Helgesson Stefan 
Published: March 2024

Abstract
Focusing on the reception of the two Nobel laureates Nadine Gordimer and J.M. Coetzee, this article investigates the literature prize as a national, and indeed Stockholm-based, phenomenon in Sweden. It makes two general claims. The first is that the press exercises a co-consecrating authority that both rivals and depends on the authority of the Swedish Academy. This becomes evident not least in occasional attempts by critics to deconsecrate a laureate. The second claim is that the dramaturgy of the literature prize, beginning with the announcement in October and ending with the award ceremony in December, culminates shortly before the ceremony with the Nobel lecture, when the laureate is heard in their own voice. In an analysis of Gordimer’s and Coetzee’s lectures, the article concludes that they present sharply different attempts at performatively resolving the tension between literary autonomy and heteronomy.
The Visual Economy of Cultural Consecration
Authors: Yacavone Kathrin 
Published: March 2024

Abstract
This article explores the impact of the Nobel Prize on the visual economy of literary culture by analysing how photographic author portraits are used by the Nobel Foundation and the Swedish Academy to construct a visual pantheon of literary laureates. The photographic Nobel pantheon is here conceptualised as a transnational visual construction that has a unique symbolic function in demarcating, homogenising, and essentialising the global literary field. It is argued that the images, together with their use by the consecrating institutions, ‘mythologise’ the author persona as a timeless, supra-national essence rather than presenting the more accurate picture of an historically, nationally, and culturally specific and contingent conception of literature. In analysing the semiotic structures and functions, as well as aesthetic patterns of photographic author portraits in relation to implicit notions of authorship, the article thereby shines a critical light on institutional ideology and its relation to visual culture.
The Look of the Book
Authors: Nienhaus Sarah A. 
Published: March 2024

Abstract
This paper shows how book design responds to the Nobel’s prestige. Using previously unpublished materials from German publishing archives, I explore how the Nobel Prize is accompanied by the requirement to design iconic books. This unique material documents how different players in the publishing industry exchange ideas about ‘Nobel Prize-appropriate’ book design. This applies, for example, to the illustrations for an essay by Octavio Paz, designed covers for Nadine Gordimer, and the pictorial representation of Günter Grass’s and Tomas Tranströmer’s ‘life and work’.
The ‘Most Ideal’ Peter Handke?
Authors: Bareis J. Alexander 
Published: March 2024

Abstract
The Nobel Prize in Literature to the Austrian writer Peter Handke in 2019 gave new attention to one of the basic, and historically highly disputed (cf. Espmark 2001, 2021), questions in relation to the practice of the world’s most important literary prize – on what grounds, aesthetic or otherwise, does the Swedish Academy award the prize? In the aftermath of the 2019 prize to Handke, there was an intense public debate about the aesthetic criteria in relation to ethical criteria, in particular in Swedish national newspapers. Several members of the Academy as well as members of the Nobel Prize committee, wrote articles and gave statements about their individual reasoning for awarding the prize to Handke. Using this debate about the prize awarded to Handke as a case study, I aim to discuss the methodological and theoretical implications connected to the question of which criteria guide the selection of the Nobel Prize in Literature.
Japan’s Quest for the Nobel Prize in Literature and Its Aftereffects
Authors: Inoue Takashi 
Published: March 2024

Abstract
This paper examines Japan’s quest for the Nobel Prize in Literature as a narrative “before” winning, and its aftereffect as a narrative “after” winning. It first draws from archival material to discuss the roles of diplomacy, the context of Cold War politics and translation techniques in Kawabata Yasunari’s win. Next, it explores how Oe Kenzaburo responded to the negative acceptance of his win in Japan, referring to the court decision on record and Oe’s manuscripts. Overall, this paper shows that the stereotypically held belief that laureates are commended solely for their literary superiority, and are therefore revered in their home countries, does not fully describe the complicated reality.

Published: March 2024

This study examines the safety and efficacy of using peak anti-Xa levels to achieve prophylactic enoxaparin (Lovenox, Sanofi-Aventis) levels in patients who underwent hepatic surgery. Prospectively enrolled patients undergoing major and minor hepatic procedures received postoperative enoxaparin dosing. The enoxaparin dose was adjusted to attain a peak anti-Xa level ≥ 0.20 U/ml. This group was compared to a historical cohort of patients who underwent similar procedures and received standard postoperative VTE chemoprophylaxis dosing. Inpatient postoperative VTE rates were higher in the control group when compared to the experimental group (0 patients [0.00%] vs 4 patients [8.16%]; P = .035). There was no statistically significant difference in number of postoperative blood transfusions, discharge hemoglobin, or in-hospital bleeding events. Adjusting enoxaparin dosing to achieve prophylactic peak anti-Xa levels of ≥0.20 IU/ml was associated with a reduced incidence of symptomatic inpatient postoperative VTE in patients who underwent hepatic surgery without increasing postoperative bleeding events.

Published: March 2024

Objective: Compare ventilation pressures of 2 endotracheal tube designs used in laser airway surgery in clinical practice and with a benchtop model to elucidate differences and understand the design elements that impact airflow dynamics. Methods: Ventilatory and aerodynamic characteristics of the laser resistant stainless-steel endotracheal tube (LRSS-ET) design and the laser resistant aluminum-wrapped silicone endotracheal tube (LRAS-ET) design were compared. Ventilatory parameters were collected for 32 patients undergoing laser-assisted airway surgery through retrospective chart review. An in vitro benchtop simulation measured average resistance and centerline turbulence intensity of both designs at various diameters and physiological frequencies. Results: Baseline patient characteristics did not differ between the 2 groups. Clinically, the median LRAS-ET peak inspiratory pressure (PIP; 21.00 cm H2O) was significantly decreased compared to LRSS-ET PIP (34.67 cm H2O). In benchtop simulation, the average PIP of the LRAS-ET was significantly lower at all sizes and frequencies. The LRSS-ET consistently demonstrated an increased resistance, although no patterns were observed in turbulence intensity data between both designs. Conclusion: The benchtop model demonstrated increased resistance in the LRSS-ET compared to the LRAS-ET at all comparable sizes. This finding is supported by retrospective ventilatory pressures during laser airway surgery, which show significantly increased PIPs when comparing identically sized inner diameters. Given the equivocal turbulence intensity data, these differences in resistance and pressures are likely caused by wall roughness and intraluminal presence of tubing, not inlet or outlet geometries. The decreased PIPs of the LRAS-ET should assist in following lung protective ventilator management strategies and reduce risk of pulmonary injury and hemodynamic instability to the patient.

Published: March 2024

Background: Little is known about trauma and its mental health impact on Native Hawaiians/Pacific Islanders (NH/PI), an understudied Indigenous-colonized population that endures severe mental health disparities. Aims: This novel investigation assessed trauma prevalence and its mental health and substance use correlates in NH/PIs in the U.S. Method: Using community-based participatory research methods, survey data on NH/PI trauma, depression, anxiety, substance use, and treatment need were collected from 306 NH/PI adults using online, telephone, and in-person methods. Descriptive statistics and adjusted regression models were employed. Results: Sixty-nine percent of participants experienced lifetime trauma, reporting mean exposure to 2.5 different trauma types. Childhood physical and sexual abuse, and lifetime forced sexual assault rates were 34%, 25%, and 27%, respectively, exceeding general population rates. Women and men reported equivalent total mean exposure to different trauma types, as well as equal prevalence for every trauma type examined (e.g. sexual abuse/assault). Confirming hypotheses, after controlling for key demographic and mental health risk factors, increased exposure to multiple trauma types uniquely associated with greater depression, anxiety, alcohol symptomology, and greater likelihood for needing treatment and using illicit substances. Conclusions: Trauma is prevalent in NH/PI populations and significantly impacts NH/PI mental health; serving as an important but overlooked contributor to NH/PI mental health disparities. Current findings fill critical gaps in our knowledge of NH/PI trauma and mental health while revealing the importance of screening and treating NH/PIs for trauma exposure to alleviate existing mental health disparities.

Published: March 2024

The increasing advancements in science and technology have led to a growing demand for wearable products. In this paper, copper sulfide/melamine foam composites were prepared by chemical deposition of copper sulfide on the melamine foam skeleton. The effects of different deposition amount of copper sulfide on its microstructure, and electrical conductivity were studied. The results showed that the composite had good electrical conductivity and flexibility when the reaction solution concentration was 1 wt.%. The material can be used as an electric heater, the surface of the material can be heated to 145°C under the low voltage of 4 V, and the material can also be used as a flexible pressure sensor with a high sensitivity of 0.385 kPa−1 and a stability of more than 2000 cycles. Materials based on flexible copper sulfide/melamine foams can be used for electric heaters and flexible pressure sensor, which will make them promising applications in wearable products.

Published: March 2024

The objective of this study was to develop polymeric films of high-density polyethylene (HDPE)/low-density polyethylene (LDPE) that comprise 1 wt% of different nanofillers, that is, either nanofibrillated cellulose (NFC), montmorillonite clay (MMT), or graphene nanoplatelets (GNPs); the polymeric films were developed with and without the inclusion of a coupling agent (CA). The results indicated that all the samples that comprised nanofillers exhibited, at least, an increase of 3 to 25°C compared with that of the matrix and demonstrated higher stability at the beginning of the thermal degradation, as verified using TGA. In the DSC analysis of the samples that contained GNPs had highest crystallinity index (55%), having as the consequent improvement in the mechanical properties and in the oxygen permeation. The incorporation of GNPs provided a 127.71% increase in deformation at break and a lower value in oxygen permeability with 50.06 mL.cm.(cm2.s.cmHg)−1, when compared to the polymeric matrix. It was concluded that all the different nanofillers tested promoted distinct improvements in HDPE/LDPE films nanocomposite. It can be inferred that these modifications are related to the chemical composition, size and morphology of each nanofiller. Thereby, it is indicated that with the use of each nanofiller one must be in accordance with the necessary demand of each composite film.

Background Tuberculosis (TB) is one of the most common infections among systemic lupus erythematosus (SLE) patients. We aimed to evaluate the global prevalence of TB infection and disease, its type, and medication risk factors in SLE patients. Methods We searched PubMed, Science Direct, EBSCO, and Web of Science databases from inception to April 30, 2023, and included studies assessing TB among SLE patients. We estimated the prevalence of TB disease (including type of TB disease), TB infection, and SLE medication as TB risk factors. Meta-analysis was performed using Stata 14.2 and Review Manager 5.3. Results Twenty-seven studies met the eligibility criteria. The global prevalence of TB disease was 4% (95% confidence interval (CI): 3–4%, n = 25) and TB infection was 18% (95% CI: 10–26%, n = 3). The pooled prevalence of pulmonary TB, extrapulmonary TB, and disseminated TB were 2% (95% CI: 2–3%, n = 20), 1% (95% CI: 1–2%, n = 17), and 1% (95% CI: 0–1%, n = 6), respectively. The 1-year cumulative glucocorticoid (GC) dose in SLE patients contracting TB was higher than in those without TB, having a mean difference of 2.56 (95% CI: 0.22–4.91, p < .00001, n = 3). The odd ratio of TB was 2.11 (95% CI: 1.01–4.41, p = .05, n = 3) in SLE patients receiving methylprednisolone (MP) pulse therapy as compared to those without MP pulse therapy. Other immunosuppressive agents were not significantly associated with TB. Conclusion TB prevalence in SLE was relatively high and associated with GC. Awareness of TB and lowering GC dose are warranted to alleviate the TB burden in SLE.

Published: March 2024

Background Euthanasia is a controversial practice in many countries. Since Spain’s Euthanasia Law came into effect on March 24, 2021, healthcare providers have faced a new challenge since they must inform patients, provide care, accompany them, and implement the law. It also represents a new stumbling block at universities, which must adapt to regulatory changes and educate future professionals accordingly. Little is known about the attitude of nursing students in Spain toward euthanasia since this law was implemented. Objective This study aims to answer the following research questions: What is the attitude of nursing students toward euthanasia? What factors influence this attitude? Research design A cross-sectional study was conducted using an online questionnaire. Participants and research context The study population comprised all nursing students at a public university in Barcelona ( n = 444), Spain, during the 2022–2023 academic year. The validated Spanish version of the Euthanasia Attitude Scale was employed. A bivariate analysis was performed. Ethical considerations The university Ethics Committee (CEEAH 6247) approved this study. All participating students signed an informed consent form. Participation was voluntary, and data anonymity and confidentiality were guaranteed. Results Two hundred and forty-four nursing students responded to the questionnaire. The mean total score was 79.64. Participants with religious beliefs presented lower scores, indicating a more negative attitude toward euthanasia. Participants in their second, third, or fourth year of the nursing degree scored higher, demonstrating a more positive attitude. Conclusions The attitude of nursing students toward euthanasia was remarkably positive. Working on ethical content during the degree course and clinical practice are factors that help to develop a more positive attitude. In addition, nursing education should encourage professional aspects to prevail over religious beliefs in euthanasia situations.
