Authors: Hu Xiaoxiang , Guo Chenguang , Hu Changhua , He Bing 
Published: April 2022

AbstractSliding mode‐based learning control is presented for T‐S fuzzy system. A T‐S fuzzy model with both uncertainties and unmodeled dynamics is proposed firstly, in which the information of uncertainties and unmodeled dynamics are assumed to be unknown. Then, according to a given reference model, state‐tracking error system is built. Respecting facts, the input matrices of the built T‐S fuzzy model are different from each other. An extended state observer is built for estimating the unknown uncertainties and unmodeled dynamics, and a corresponding sliding surface is proposed. A learning controller is then presented for the closed loop system. Moreover, a numerical simulation result on hypersonic flight vehicles is considered to testify the controller's availability.

Published: April 2022

AbstractThe relationship between augmented reality (AR) in mobile applications and consumers' online impulse purchase intention is still at its nascent stage. This study focuses on the cosmetics category under online purchase. Firstly, it examines the relationship between women consumers' motivation to use AR in the mobile app, vis a vis perceived quality of augmentation on perceived value. Secondly, it also tests the relationship between perceived value and impulsive online purchase. Thirdly, it examines the mediating role of perceived value between two exogenous variables and impulsive intention of online purchase. Further, it tests the moderating role of product involvement between perceived value and impulsive intention of online purchase. We collected data from 343 millennial women respondents and analyzed them using PLS‐SEM. The results highlight that AR in mobile applications can lead to impulsive purchase intentions among millennial women.

Published: April 2022

AbstractNitrile hydratase (NHase) is an excellent biocatalyst for the synthesis of amide compounds and is composed of two heterologous subunits. However, the secretory expression of NHase has been difficult to achieve because of its complex expression mechanism. In this work, a novel fluorescent probe Rho‐IDA‐CoII was synthesized by a one‐pot method. Rho‐IDA‐CoII could specifically label His‐tagged proteins in vitro, such as for staining in‐gel, Western blot, and ELISA analysis. Furthermore, Rho‐IDA‐CoII combined with dot blots could quantitatively detect His‐tagged proteins at between 1–10 pmol and perform high‐throughput screening for the NHase signal peptide library. Recombinant Bacillus subtilis WB800/phoB‐HBA with the extracellular expression of NHase was screened (ca. 6500 clones). After optimization of fermentation conditions, the NHase activity in the culture supernatant reached 17.34±0.16 U/mL. This is the first time that secretory NHase has been expressed in B. subtilis successfully.

Published: April 2022

AbstractHymen imperforation is uncommon. Symptoms include primary amenorrhea, cyclical lower abdominal pain, and rarely a pelvic mass syndrome. Delayed discovery may lead to endometriosis and infertility. Pelvic ultrasound and nuclear magnetic resonance detect associated genito‐urinary malformations. Hymenectomy is the standard surgical treatment.
Impact of N‐Aryl‐ and NHC Core‐Substituents on the Coupling of Alkylzinc Nucleophiles: Is Bigger always Better?
Authors: Eckert Philip , Organ Michael G. 
Published: April 2022

AbstractBulky Pd−N‐heterocyclic carbene (NHC) catalysts (e. g., N‐(di‐2,6‐(3‐pentyl)phenyl), IPent) have been shown to have significantly higher reactivity in a wide variety of cross‐coupling applications (i. e., C−C, C−S, C−N) than less hindered variants (e. g., N‐(di‐2,6‐(isopropyl)phenyl), IPr). Further, chlorinating the backbone of the NHC ring sees an even greater increase in reactivity. In the cross‐coupling of (hetero)aryl electrophiles to secondary alkyl nucleophiles, making the N‐aryl groups larger reduces the amount of β‐hydride elimination leading to alkene byproducts and chlorinating the NHC core had an even greater effect, all but eliminating alkene formation. In the present study involving the cross‐coupling of primary alkyl electrophiles and nucleophiles, a sharp and surprising reversal of all of the above trends was observed. Bulkier catalysts had generally slower rate of reaction and β‐hydride elimination worsened leading to extensive amounts of alkene byproducts.
Changes in properties of H2 molecules at the fluid–fluid phase transition in warm dense hydrogen
Authors: Sartan Roman A. 
Published: April 2022

AbstractThe warm dense hydrogen is studied in the region of the fluid–fluid phase transition in the density functional theory framework. A formalized definition of the term “molecule” based on geometry is proposed for calculating the concentration of molecules H2 and their lifetime. Correlations between density, conductivity, H2 molecules' lifetime, interatomic distance, and their dissociation degree are studied. The transition from molecular fluid to atomic fluid is not abrupt, while there is a drastic change in the H2 molecules' lifetime at the density, where the phase transition occurs. It can be interpreted as the ionization of H2 to plus e− at the phase transition, and the start of dissociation of to H plus H+ right after the phase transition.
Racism, Not Race: A Physician Perspective on Anti‐Black Racism in America
Authors: Clayborne Elizabeth P. 
Published: April 2022

AbstractIn this commentary, which responds to the article “Anti‐Black Racism as a Chronic Condition,” by Nneka Sederstrom and Tamika Lasege, I draw on my experience as a physician who cares for a largely Black patient population. Physicians are trained to “first do no harm” and strive to treat patients to the best of their abilities. However well intentioned, many of us fall short of this goal and witness the consequences of health inequities that disproportionally impact the lives of Black patients. Recent years have brought increased acknowledgment and understanding of social determinants of health, but these modest changes fail to identify the true culprit of health disparities. Racism, not race, is responsible for the negative outcomes that we see in our communities of color. Both subtle and overt forms of systemic racism plague the educational systems and scientific metrics of medicine in the United States. Physicians’ training, culture, and biases are founded in White norms. To decenter Whiteness as a normality, medicine must enact a multipronged approach that begins with increasing the diversity of physicians and providers to better reflect the patients that they care for. Bioethicists must publicly state that racism is real and that we are dedicated to changing it, but to get beyond statements, we must also have a measure of improvement and success in battling racism.
Anti‐Black Racism and Power: Centering Black Scholars to Achieve Health Equity
Authors: Best Alicia L. 
Published: April 2022

AbstractIn health equity research, anti‐Black racism and power imbalances manifest at every phase of the research process and contribute to the marginalization and exclusion of Black scholars. This essay highlights how power operates as a central component of anti‐Black racism, and I describe the importance of centering Black scholars in funding, conducting, and implementing health equity research. Interdisciplinary collaboration between the fields of bioethics, public health ethics, and health equity could generate dialogue and develop recommendations to help balance power dynamics, address anti‐Black racism, and, ultimately, make meaningful progress toward health equity.
Holding Them Accountable: Organizational Commitments to Ending Systemic Anti‐Black Racism in Medicine and Public Health
Authors: Ray Keisha S. 
Published: April 2022

AbstractIn this essay, I detail commitments that some of the major health organizations—the American Medical Association, the American Public Health Association, and the Centers for Disease Control and Prevention—have made to addressing anti‐Black racism and discuss their policies meant to curtail racism's effects on health equity. Although these organizations’ historical lack of action has contributed to a culture of anti‐Black racism in health care and public health and many Black people have suffered because of it, progress has to begin somewhere, and outlining their future actions is a good start. Now, bioethicists, with our expertise in how historic policies connect to contemporary disparate health outcomes and access to health care, are in a position to hold these organizations accountable for fulfilling their commitments.
Black and Waiting: Bioethics and Care during the Covid‐19 Pandemic
Authors: Collins Mali 
Published: April 2022

AbstractIn this essay, a Black scholar of the cultural histories of Black women's reproductive lives launches a discussion of generations of racism, health inequities, and violence against Black bodies by looking at Black poet and essayist Dionne Brand's critique of the notion of returning to “the normal” after the Covid‐19 pandemic. To what, the essay asks, is everyone so eager to return? The intergenerational wait for Black people's moment of racial reckoning is its own unique biomedical warfare, which cannot end with the end of a pandemic. This warfare undercuts Black people's daily health with anxiety and depression, altering the very chromosomes passed down to their children. To health care providers, bioethicists, and those who practice antiracist health work the author poses these questions: How will you confront anti‐Black racism within every formulation of “treatment”—diagnosis, care, medication distribution, physical therapy? How long will the violence against Black lives be dissolved into talking points about our bodies? How can one listen, ethically, to Black people? These, she asserts, are questions of practice, of politics, and of care.

Study to assess the utility of discrete event simulation software in projection & optimization of resources in the out‐patient department at an apex cancer institute in India
Authors: Singh Angel Rajan , Gupta Anant , Satpathy Sidhartha , Gowda Naveen 
Published: April 2022

AbstractBackground and AimsA study was done to create and run a discrete event simulation in the outpatient department (OPD) of a tertiary care cancer hospital in North India to project and optimize resource deployment.MethodsThe OPD process & workflow as per the expected load at tertiary care cancer hospital were finalized with various stakeholders in a focused group discussion. The finalized OPD process & workflow along with the OPD Building plans were utilized to develop a discrete event simulation model for the OPD at a tertiary care cancer hospital using a discrete event simulator. The simulation model thus developed was tested with incremental patient loads in 5 different scenarios/“What if” situations (Scenario 1–5). The data regarding initial patient load and resources deployed was taken from on‐ground observations at the tertiary care cancer hospital.ResultsIt was found that rooms and doctors were over‐utilized and support staff utilization remained low. This was implemented with a lesser waiting time for patients. No additional support staff was provided thus improving utilization of existing staff and saving on resources. The simulations enabled us to deploy resources just when it was required, which ensured optimal utilization and better efficiency. The peak census helped us to determine the capacity of the waiting area in different scenarios with incremental patient load and resource deployment.ConclusionThe simulation software was very helpful, as “what if scenarios” could be created and the system tested, without disturbing the normal functioning of OPD. This enabled decision‐making before making on‐ground changes which saved a lot of time and money. Also, the processes of the old system were reengineered to fit the needs of changing times.

IntroductionBK virus‐associated hemorrhagic cystitis is a significant complication of hematopoietic stem cell transplantation. Although severe BK virus‐associated hemorrhagic cystitis is associated with treatment‐related mortality, sufficient evidence regarding its management is lacking.Case presentationA 14‐year‐old boy presented with BK virus‐associated hemorrhagic cystitis and bladder clot retention after hematopoietic stem cell transplantation. Various urological interventions failed to improve cystitis. While bladder clot retention frequently recurred, surgical intervention was difficult because of the underlying hematological disorder. Hence, bilateral single‐J ureteral stenting followed by Foley catheter placement was performed as a urinary diversion. The bladder clot completely disappeared 27 days after stenting. No additional procedure was required. BK virus‐associated hemorrhagic cystitis did not recur after the blood clot disappeared.ConclusionBilateral single‐J ureteral stenting followed by Foley catheter placement is a simple and effective treatment method and should be considered before surgical intervention for severe BK virus‐associated hemorrhagic cystitis.
Water table dynamics between two adjacent subsurface drainage laterals in a paddy field: A newly improved analytical solution
Authors: Jafari Talukolaee Mehdi , Shahnazari Ali , Ritzema Henk 
Published: April 2022

AbstractInstallation of subsurface drainage systems in paddy fields is crucial to achieve the feasibility of year‐round cropping and high productivity and to create more conducive working conditions for the use of farm machinery. Therefore, three subsurface drainage systems were installed in a paddy field located in northern Iran to control the water table (WT) during the rainy seasons. To predict the WT between subsurface drainage systems in the field, an analytical solution of two‐dimensional transient saturated flow was presented using the Bear equation. In the next step, a modified procedure was developed to separately involve the vertical head due to the existence of clayey and layered soils in the studied field. The results of the solutions were compared with the collected field data. The obtained results for the WT profile indicated that the modified procedure had a better agreement with the field data (9%–13% differences) in comparison with the conventional two‐dimensional solution (23%–75% differences). This revealed that considering the vertical head in the media cannot be ignored in analytical or numerical simulations of WT dynamics. As a concluding result, the modified procedure was found to be more efficient in paddy field drainage design.
Product market competition and operating leverage: International evidence*
Authors: Babar Md. , Habib Ahsan 
Published: April 2022

AbstractThis study examines the association between product market competition (PMC) and operating leverage for a large sample of international firms from 46 countries spanning the period 1985–2019. Using the Herfindahl‐Hirschman (HH) index and the Industry Adjusted Price Cost Margin (IPCM) as two proxies for PMC, we provide evidence that PMC is significantly and positively associated with the operating leverage of firms. Cross‐sectional analyses reveal that investment intensity, firm life cycle and the country‐level employment protection legislation moderate the relationship between PMC and operating leverage. This study contributes to the scarce literature on the determinants of operating leverage. We expect our findings to be informative for investors in understanding the role market competition plays in shaping cost structures.
Social prescribing from the patient's perspective: A literature review
Authors: Araki Kazuo , Takahashi Yoshimitsu , Okada Hiroshi , Nakayama Takeo 
Published: April 2022

AbstractSocial prescribing (SP) has aroused widespread interest across countries. SP is a way of linking patients in primary care with sources of support within the community by empowering patients to coproduce solutions to improve their health and well‐being. While previous research has demonstrated that SP contributes to reducing the total cost of the National Health Service, the analysis of its effects on patients is still inadequate. This literature review critically evaluated SP from the patient's perspective through the lens of medical anthropology. The review was made with respect to the three key concepts: treatment evaluation, coproduction, and empowerment. The study revealed that SP services in the UK enabled patients to feel comfort in many cases, but general practitioners, link workers, and patients should be collaborative with each other, and their interrelationships should not be hierarchical. Nevertheless, certain modifications may be needed to introduce SP in other healthcare systems.
Use of natural low‐methoxyl pectin from sunflower by‐products for the formulation of low‐sucrose strawberry jams
Authors: Muñoz‐Almagro Nerea , Garrido‐Galand Sara , Taladrid Diego , Moreno‐Arribas M. Victoria , Villamiel Mar , Montilla Antonia 
Published: April 2022

AbstractBACKGROUNDDue to the increasing incidence of obesity and cardiovascular diseases, consumers are demanding products with lower sugar content. In this sense, the reformulation of traditional foods with improved, safe and tasty ingredients is arousing a huge interest. Jams are conventionally produced with elevated amounts of sucrose, which increase the glycaemic index and must be avoided in certain kinds of consumers.RESULTSThis paper describes for the first time the elaboration of strawberry jams using low‐methoxyl pectins from sunflower by‐products, which allowed the addition of low amounts of sucrose (10–30%). These jams were compared with best‐selling commercial samples. An in‐depth physicochemical, compositional, sensorial and rheological characterization was carried out. The obtained jams were safe considering aw and pH values; samples presented enough acidity to avoid microorganism development and syneresis. The stabilizing role of sunflower pectin is noteworthy in terms of colour and other physicochemical characteristics. The organoleptic analysis showed that the taste and sweetness of laboratory samples were highly valued, although the presence of pieces of fruits was disliked some panellists. After knowing the content of added sugar used in each jam, the tasters preferred samples with 20% and 30% of sucrose over commercial samples.CONCLUSIONSThe results show the usefulness of sunflower pectin for the elaboration of jams of low glycaemic index. © 2022 The Authors.
