Decolonizing health policy and practice: Vaccine hesitancy in the United States
Authors: Hatcher Barbara 
Published: March 2023

AbstractUsing 2021 data and information related to COVID‐19, this paper discusses the contribution of colonization, medical mistrust and racism to vaccine hesitancy. Vaccine hesitancy is defined as ‘delay in acceptance or refusal of vaccines despite availability’. Colonization is described as the ‘way the extractive economic system of capitalism came to the United States, supported by systems of supremacy and domination, which are a necessary part of keeping the wealth and power accumulated in the hands of the colonizers and ultimately their financiers’. The system of colonization results in policies and practices, including those related to health, that continue to create oppression and support racism. Persons experience trauma as the byproduct of colonization. Chronic stress and trauma create chronic inflammation and all diseases, whether genetic or lifestyle, have a common pathogenesis that is a component of inflammation. Medical mistrust is the absence of trust that healthcare providers and organizations genuinely care for patients' interests, are honest, practice confidentiality and have the competence to produce the best possible results. Finally, racism is described as everyday racism and perceived racism in healthcare.
Refashioning place and new‐build gentrification: The material and symbolic redevelopment of Three Kings, Auckland
Authors: Naismith Larissa , Murphy Laurence 
Published: March 2023

AbstractAuckland's post‐suburban landscape is associated with new mixed‐use apartment developments. When located in former industrial sites, these emergent residential and retail spaces constitute new‐build gentrification and carry the potential to rupture existing people/place dynamics. This article examines material and socio‐cultural processes associated with the redevelopment of an industrial quarry in Three Kings, Auckland. It is argued that the redevelopment constitutes a physical refashioning of a former industrial space located within a traditional working‐class community. The development involves a remaking of the material and socio‐cultural fabric of the neighbourhood and aligns with new‐build gentrification practices.

Published: March 2023

A plethora of literature has investigated the voting behavior of US legislators on trade bills to reveal a possible causal mechanism. Relying on dichotomous roll‐call voting data, however, has certain limitations on revealing the comprehensive thought probes of lawmakers on a complex diplomatic issue such as making an FTA deal. In this paper, we provide new insight to fill such a gap by analyzing congressional speech data during FTA ratification procedures. Using an automated web scraper, we collected the entire speech data (N = 5,372) of Senators and House Representatives in the 108th and 112th US Congress regarding AUSFTA and KORUS FTA, respectively. The speech sentiment analysis results show background and context (i.e., attitude‐behavior inconsistency) in the process of trade negotiations and agreements. Additionally, the results help identify important factors (i.e., ideology, constituency stimuli) that influence whether members of Congress stand for and against the FTA implementations.

AbstractCiliated muconodular papillary tumor/bronchiolar adenoma (CMPT/BA) is a recently introduced benign lung tumor. It remains unclear whether CMPT/BA is associated with a specific type of lung cancer (LC). We studied the clinicopathological characteristics and genetic profiles of the coexisting primary LC and CMPT/BA (LCCM) cases. We identified eight LCCM (0.4%) from the resected Stage 0–III primary LC (n = 1945). The LCCM cohort was male‐dominant (n = 8), elderly (median 72 years old), and most were smokers (n = 6). In addition to the adenocarcinoma (n = 8), we detected two squamous cell carcinomas and one small cell carcinoma—in some cases, multiple cancer. The target sequence/whole exome sequence (WES) revealed no shared mutations between CMPT/BA and LC. One exceptional case was invasive mucinous adenocarcinoma harboring an HRAS mutation (I46N, c.137T>A), but it was likely to be a single nucleotide polymorphism based on variant allele frequency (VAF). Other driver mutations in LC included EGFR (InDel, n = 2), BRAF(V600E) (n = 1), KRAS (n = 2), GNAS (n = 1), and TP53 (n = 2). BRAF(V600E) was the most frequent mutation in CMPT/BA (60%). In contrast, LC showed no specific trend in driver gene mutations. In conclusion, our study revealed differences in the gene mutation profiles of CMPT/BA and LC in coexisting cases, suggesting mostly independent clonal tumorigenesis of CMPT/BA from LC.

AbstractThe quantification of resting‐state electroencephalography (EEG) is associated with a variety of measures. These include power estimates at different frequencies, microstate analysis, and frequency‐resolved source power and connectivity analyses. Resting‐state EEG metrics have been widely used to delineate the manifestation of cognition and to identify psychophysiological indicators of age‐related cognitive decline. The reliability of the utilized metrics is a prerequisite for establishing robust brain–behavior relationships and clinically relevant indicators of cognitive decline. To date, however, test–retest reliability examination of measures derived from resting human EEG, comparing different resting‐state measures between young and older participants, within the same adequately powered dataset, is lacking. The present registered report examined test–retest reliability in a sample of 95 young (age range: 20–35 years) and 93 older (age range: 60–80 years) participants. A good‐to‐excellent test–retest reliability was confirmed in both age groups for power estimates on both scalp and source levels as well as for the individual alpha peak power and frequency. Partial confirmation was observed for hypotheses stating good‐to‐excellent reliability of microstates measures and connectivity. Equal levels of reliability between the age groups were confirmed for scalp‐level power estimates and partially so for source‐level power and connectivity. In total, five out of the nine postulated hypotheses were empirically supported and confirmed good‐to‐excellent reliability of the most commonly reported resting‐state EEG metrics.
Conceptualization and measurement of regulatory discretion: Text analysis of 120 years of British legislation
Authors: Kosti Nir 
Published: March 2023

AbstractRegulatory discretion is a central concept in the study of the regulatory state. Yet little attention has been paid to the origins of regulatory discretion, and how it varies across polities, policy areas, and over time. This paper presents a conceptualization of regulatory discretion that draws on three dimensions: delegation, content, and procedure. It argues that to measure regulatory discretion in legislation, we need to identify provisions that delegate regulatory powers to governments and then examine the extent to which exercising regulatory powers is constrained. Using Natural Language Processing techniques, this paper presents descriptive findings of the dynamics of regulatory discretion in the United Kingdom between 1900 and 2020. The findings portray how discretion has been constrained and formalized over the years through the content of regulations, while it has still retained high levels of flexibility in exercising regulatory powers. In doing so, the findings illustrate the rise of the British regulatory state through its legislative language.

AbstractIntroductionThis study investigated demographic differences in interpersonal theory of suicide factors and their associations with suicide attempts among sexual minority young adults.Methods784 sexual minority young adults ages 18–29 (42.7% cisgender men, 42.2% cisgender women, 15.1% transgender/gender diverse; 62.2% non‐Hispanic White; 50.5% gay/lesbian, 49.5% bisexual+) completed an online survey assessing lifetime suicide attempts and interpersonal theory of suicide factors.ResultsDemographic differences included (1) greater perceived burdensomeness among transgender/gender diverse participants compared to other gender groups; (2) greater acquired capability for suicide and suicide attempts among cisgender men compared to cisgender women; (3) greater acquired capability for suicide among bisexual+ compared to gay/lesbian participants; and (4) a lower number of suicide attempts among Asian/Asian American sexual minority participants compared to most other sexual minority participants. All interpersonal theory of suicide factors were significantly associated with a higher number of suicide attempts, though only perceived burdensomeness and acquired capability for suicide remained significant when examining all three simultaneously. No two‐ or three‐way interactions between interpersonal theory of suicide factors were significant.ConclusionThe interpersonal theory of suicide may be useful for understanding suicide attempts in this population, with perceived burdensomeness and acquired capability being particularly relevant to consider.

AbstractBackground and ObjectivesIdentification of antibody characteristics and genetics underlying the development of maternal anti‐A/B linked to inducing haemolytic disease of the foetus and newborn could contribute to the development of screening methods predicting pregnancies at risk with high diagnostic accuracy.Materials and MethodsWe examined 73 samples from mothers to 37 newborns with haemolysis (cases) and 36 without (controls). The secretor status was determined by genotyping a single nucleotide polymorphism in FUT2, rs601338 (c.428G>A).ResultsWe found a significant association between secretor mothers and newborns developing haemolysis (p = 0.028). However, stratifying by the newborn's blood group, the association was found only in secretor mothers to blood group B newborns (p = 0.032). In fact, only secretor mothers were found in this group. By including antibody data from a previous study, we found higher median semi‐quantitative levels of IgG1 and IgG3 among secretor mothers than non‐secretor mothers to newborns with and without haemolysis.ConclusionWe found that the maternal secretor status is associated with the production of anti‐A/B, pathogenic to ABO‐incompatible newborns. We suggest that secretors experience hyper‐immunizing events more frequently than non‐secretors, leading to the production of pathogenic ABO antibodies, especially anti‐B.

AbstractBackground and ObjectivesNo systematic study has measured the incidence of adverse reactions (ARs) to blood donation at the national level in China before 2019. The objective of this study was to establish an effective reporting system to collect information on ARs to blood donation in China.Materials and MethodsThe status of donor haemovigilance (DHV) in blood collection facilities in China was evaluated, and an online DHV system was established to collect data on ARs to blood donation in July 2019. The definitions of ARs were based on the International Society of Blood Transfusion (ISBT) standards. The prevalence and data quality of ARs from 2019 to 2021 were analysed.ResultsA standard online reporting system has been established for ARs to blood donation. In total, 61, 62 and 81 participating sites were included in this pilot study in 2019, 2020 and 2021, respectively. From July 2019 to December 2021, 21,502 cases of whole‐blood‐related ARs and 1114 cases of apheresis platelet‐related ARs were reported, with an incidence of 3.8‰ and 2.2‰, respectively. Data completeness for key reporting elements improved from 41.7% (15/36) in 2019 to 74.4% (29/39) in 2020. Data quality analysis for the year 2021 yielded similar results as for 2020.ConclusionThe construction and continuous improvement of the blood donor safety monitoring system prompted the establishment of the DHV system. Improvements have been made to the DHV system in China, with a significant increase in sentinels and higher data quality.

AbstractA numerical study has been carried out on the two-dimensional flow past a circular cylinder. In this case, a splitter plate is provided at the rear stagnation point in the downstream direction. ansys fluent has been used to carry out the numerical simulations based on finite volume method approach. Grid independence was achieved and the numerical model was validated with results available in open literature at Reynolds numbers of 100, 5000, and 100,000 respectively. In the present investigation, the characteristics of vortex shedding due to the presence of splitter plate in the circular cylinder were investigated. The main focus of this research was to find the optimal splitter plate length for low, moderate, and high Reynolds numbers. It was observed that at low, moderate, and high Reynolds numbers, the drag coefficient (cd) for optimal plate length decreased drastically as compared to the baseline circular cylinder case. Moreover, the fluctuating nature of lift coefficient (cl) had also ceased. This research work has a good potential to decrease time-varying structural loads on bluff bodies by decreasing the vortex shedding frequency and consequently decreasing drag. The scope of our research extends to structures of bridges and large vehicles, radiator pipes of heat exchangers, landing gears of aircraft, and many more.
Heat Transfer Intensification of a Confined Impinging Air Jet Via a Guiding Baffle

Published: March 2023

Abstract
The heat transfer intensification of a confined impinging jet was achieved using a rough surface or pin fins as well as using modified nozzles such as chamfering, chevron, sweeping, swirling, etc. In this work, an enhanced cooling process utilizing a single confined air jet impinged on a flat plate using a guiding baffle is implemented. The impacts of Reynolds number (Re) ranged from 500 to 5000, guiding baffle diameter-to-nozzle diameter (D/d) of 2, 4, and 6, and guiding baffle height-to-nozzle to impinging plate distance (h/H) of 1/3, 1/2, and 3/4 on the cooling process are studied. The distributions of surface temperature are acquired experimentally using a thermal infrared camera. As well, the local Nusselt number (Nu), stagnation point Nusselt number (Nust), average Nusselt number (Nu¯), and average Nusselt number ratio (Nu¯r) are evaluated. The results reveal that the enhancement of heat transfer is achieved due to installing a guiding baffle with a D/d of 2 for all values of baffle height and Reynolds number. In addition, the Nu¯r is increased with increasing the Re in the range from 500 to 2500, then it is decreased by a further increase in Re. Moreover, based on the experimental results, an empirical correlation is proposed to compute the Nu¯ depending on Re, D/d, and h/H with a ±2.65% standard deviation.
Self-Aligning Rotational Latching Mechanisms: Optimal Geometry for Mechanical Robustness

Published: March 2023

AbstractIn concurrent work, we introduced a novel robotic package delivery system latching intelligent modular mobility system (LIMMS). Each LIMMS end effector requires a small, lightweight latching mechanism for pre-manufactured containers, such as cardboard boxes. In order to effectively process a high volume of packages, aligning the latching mechanism quickly and reliably is critical. Instead of depending on highly accurate controllers for alignment, we propose a novel self-aligning rotational mechanism to increase the system’s tolerance to misalignment. The radial latching design consists of evenly spaced blades that rotate into slots cut into the box. When misaligned, the blades contact the edges of the engagement slots, generating a self-correcting force that passively centers the blades with the slot pattern. This paper introduces a mathematical framework with closed form expressions to quantify error tolerance for these mechanisms. Through our mathematical and optimization analyses, it is shown that a two-blade design can tolerate a maximum misalignment of three times the radius to the blade tips, much larger than commonly used designs with three or more blade-like contacts. Our approach can be generalized for a class of rotational latching mechanisms with any number of blades. Utilizing this theory, a design process is laid out for developing an optimal self-aligning rotational latching mechanism given desired parameters and task constraints. With this methodology, we designed, manufactured, and verified the effectiveness of both two-blade and three-blade self-aligning in practical experiments.
Comprehensive Correlations for Small Punch Test Response Post-Processing Toward Preserved Mechanical Strength Estimation
Authors: Patel Pruthvish , Patel B. K. 
Published: March 2023

Abstract
The small punch test (SPT) approach is a miniature specimen testing technique to estimate the preserved mechanical strength of an in-service component to check its fitness for service. The SPT results are summarized in form of force-specimen deflection, (F − u) and force-punch displacement, (F − v) response. There are many standards published in an attempt to define a universally accepted approach for SPT-aided mechanical characterization. However, it was recognized that such standards were not concerned to practice a consistent approach while SPT response measurement and strength estimation toward outlining proclaimed best-fitting correlations. This paper narrates limitations caused by known inconsistent practices and proposed comprehensive correlations for accurate strength estimation for metallic materials which are exposed to 100–2000 MPa strengths.
A Direct Backstepping Super-Twisting Algorithm Controller MPPT for a Standalone Photovoltaic Storage System: Design and Real-Time Implementation

Published: March 2023

Abstract
In this paper, we introduce a novel direct maximum power point tracking (MPPT) approach that combines the backstepping controller (BSC) and the super-twisting algorithm (STA). The direct backstepping super-twisting algorithm control (BSSTAC) MPPT was developed to extract the maximum power point (MPP) produced by a photovoltaic (PV) generator connected to the battery through a boost DC-DC converter. To reduce the number of sensors required for the BSSTAC implementation, a high gain observer (HGO) was proposed to estimate the value of the state of the PV storage system from measurements of the PV generator voltage and current. The suggested technique is based on the quadratic Lyapunov function and does not employ a standard MPPT algorithm. Results show that the suggested control scheme has good tracking performance with reduced overshoot, chattering, and settling time as compared to the prevalent MPPT tracking algorithms such as perturb and observe (P&O), conventional sliding mode control (CSMC), BSC, and integral backstepping controller (IBSC). Finally, real-time findings using the dSPACE DS 1104 software indicate that the generator PV can accurately forecast the MPP, as well as the efficacy of the suggested MPPT technique. The provided approach’s effectiveness has been validated by a comprehensive comparison with different methods, resulting in the greatest efficiency of 99.88% for BSSTAC.
Point Contact Thermal Mixed Elastohydrodynamic Lubrication Under Short-Period Intermittent Motion

Published: March 2023

Abstract
To improve mechanical efficiency, the tribological performance of short-period intermittent motion needs to be investigated. Based on the theory of thermal elastohydrodynamic lubrication (EHL) and considering the influences of rough surface, a mixed-EHL model under point contact simple sliding intermittent motion is established. Using this model, the transition from mixed-EHL to EHL in the contact area is realized by changing the period of intermittent motion and setting the surface roughness. It is found that the thermal effect on simple sliding intermittent motion should not be ignored, and the pressure, temperature rise distribution, and friction coefficient during the stop and start-up are fluctuated obviously. Under the condition of rough surface contact, the contact area will enter the mixed-EHL state during the stop and start-up. Shortening the period of intermittent motion is beneficial to alleviate the adverse effect of the mixed-EHL.
A Parametric Study of the Bouc–Wen Model for Bolted Joint Dynamics
Authors: Shetty Drithi , Allen Matthew 
Published: March 2023

AbstractBuilt-up structures exhibit nonlinear dynamic phenomena due to friction at the surfaces that are held together using mechanical fasteners. This nonlinearity is hysteretic or history dependent. Additionally, interfacial slip results in stiffness and damping variations that are dependent on the vibration amplitude. In the microslip regime, the dissipation varies as a power of the amplitude. The four-parameter Iwan model can capture both the hysteretic and power-law dissipation behavior that is characteristic of many bolted joints. However, simulating the dynamic response of this model is computationally expensive since the states of several slider elements must be tracked implicitly, necessitating the use of fixed-step integration schemes with small time-steps. The Bouc–Wen model is an alternative hysteretic model in which the restoring force is given by a first-order nonlinear differential equation. Numerical integration of this model is much faster because it consists of just one additional state variable, i.e., the hysteretic variable. Existing literature predominantly focuses on studying the steady-state behavior of this model. This paper tests the effectiveness of the Bouc–Wen model in capturing power-law dissipation by comparing it to four-parameter Iwan models with various parameters. Additionally, the effect of each Bouc–Wen parameter on the overall amplitude-dependent damping is presented. The results show that the Bouc–Wen model cannot capture power-law behavior over the entire microslip regime, but it can be tuned to simulate the response over a smaller amplitude range.
