Latinx identification with whiteness: What drives it, and what effects does it have on political preferences?
Authors: Filindra Alexandra , Kolbe Melanie 
Published: September 2022

AbstractObjectiveWe seek to determine the antecedents of self‐categorization as white and white identity salience among Latinx people. We also investigate the effects of both on Latinx's political preferences.MethodsWe perform multivariate regression analyses using the 2012 American National Election Survey (ANES). The survey included 1005 Latinx U.S. citizens.ResultsWe find that Latinx citizens with a strong Latino consciousness and more educated Latinx are less likely to self‐categorize as white, while those with a higher income are more likely to do so. Furthermore, we find that white identity salience correlates positively with being a Republican and a conservative and with opposition to welfare. Still, it is not a significant predictor of anti‐immigrant policy preferences.ConclusionMany Latinx show a strong attachment to white identity, and these affective ties to whiteness correlate with conservative political orientations.

SUMMARYThe spatial organization of protein synthesis in the eukaryotic cell is essential for maintaining the integrity of the proteome and the functioning of the cell. Translation on free polysomes or on ribosomes associated with the endoplasmic reticulum has been studied for a long time. More recent data have revealed selective translation of mRNAs in other compartments, in particular at the surface of mitochondria. Although these processes have been described in many organisms, particularky in plants, the mRNA targeting and localized translation mechanisms remain poorly understood. Here, the Arabidopsis thaliana Friendly (FMT) protein is shown to be a cytosolic RNA binding protein that associates with cytosolic ribosomes at the surface of mitochondria. FMT knockout delays seedling development and causes mitochondrial clustering. The mutation also disrupts the mitochondrial proteome, as well as the localization of nuclear transcripts encoding mitochondrial proteins at the surface of mitochondria. These data indicate that FMT participates in the localization of mRNAs and their translation at the surface of mitochondria.

AbstractBackgroundBacterial contamination in platelets remain a major public health concern, which prompted the US Food and Drug Administration guidance for bacterial contamination mitigation. Pathogen reduction technology (PRT) is one mitigation strategy that has shown success in Europe over the last decade. Therefore, our center sought to transition from a dual system of bacterial culturing (BacT) and PRT to full PRT.MethodsA 1 month pilot study was conducted to simulate 100% PRT conditions. Our center also collected baseline data on key platelet production metrics in the 4 months prior to 100% PRT and compared it to the 4 months post‐implementation.ResultsThe pilot study showed no statistical differences in split rate, proportion of low‐yield products, or proportion of single, double, and triple collections. The only observed difference was an 11 min increase in the average duration of double collections. Our baseline versus post‐implementation monitoring showed no difference in split rate, discard rate, percentage of low‐yield units, and average yield of low yield units. Statistical differences were detected in the proportion of single, double, and triple collections, as well as the average yield of full dose products. Roughly 20% of our inventory consisted of low‐yield products.DiscussionWith suitable mitigation strategies, transitioning to a full PRT inventory may result in higher net margins while not adversely affecting overall platelet production. A pilot study is a good way to project potential effects of switching from a dual BacT and PRT inventory to full PRT, and can be adopted by other centers aiming to make the transition.
La adaptabilidad en edificios patrimoniales
Authors: Cirvini Silvia , Gómez Voltan José Alejandro 
Published: September 2022

Este artículo sintetiza la primera etapa de un estudio en desarrollo y está dirigido a analizar el significado y alcance de la noción de “adaptabilidad edilicia disponible” en edificios históricos. Asimismo, a partir de establecer analogías con conceptos semejantes usados en otras disciplinas o saberes se ha examinado la relación entre la adaptabilidad, la vulnerabilidad y la valoración histórico-cultural.
Nuestro objetivo es establecer una técnica para evaluar cómo las características materiales del edificio se relacionan con la posibilidad de admitir cambios, en particular respecto del uso. Cuando se realiza un proyecto de reutilización, es habitual que la elección y asignación del nuevo uso o función para el bien patrimonial se realice de manera subjetiva, sin considerar ni evaluar sus condiciones y características tanto materiales como culturales. Como consecuencia de asignaciones arbitrarias del uso, las intervenciones requeridas para adecuar o “llevar” al edificio a un nuevo destino representan un forzamiento con alteraciones y modificaciones que impactan negativamente sobre su materialidad y peor aún, sobre su significación y valor cultural.
El proyecto marco que desarrollamos plantea como hipótesis que los edificios históricos poseen un potencial de adaptabilidad material inherente que representa la capacidad del edificio para responder a algún tipo cambio, en particular aquel orientado a su reutilización. Este potencial de adaptabilidad material (PAM) queda definido por un índice elaborado a partir de variables operacionales e indicadores que representan las principales condiciones y características materiales que le son propias o inherentes al bien edilicio.

Abstract
The recent COVID-19 pandemic reveals the vulnerability of global supply chains: the unforeseen supply crunches and unpredictable variability in customer demands lead to catastrophic disruption to production planning and management, causing wild swings in productivity for most manufacturing systems. Therefore, a smart and resilient manufacturing system (S&RMS) is promised to withstand such unexpected perturbations and adjust promptly to mitigate their impacts on the system’s stability. However, modeling the system’s resilience to the impacts of disruptive events has not been fully addressed. We investigate a generalized polynomial chaos (gPC) expansion-based discrete-event dynamic system (DEDS) model to capture uncertainties and irregularly disruptive events for manufacturing systems. The analytic approach allows a real-time optimization for production planning to mitigate the impacts of intermittent disruptive events (e.g., supply shortages) and enhance the system’s resilience. The case study on a hybrid bearing manufacturing workshop suggests that the proposed approach allows a timely intervention in production planning to significantly reduce the downtime (around one-fifth of the downtime compared to the one without controls) while guaranteeing maximum productivity under the system perturbations and uncertainties.

Abstract
Although teamwork is being integrated throughout engineering education because of the perceived benefits of teams, the construct of psychological safety has been largely ignored in engineering research. This omission is unfortunate because psychological safety reflects collective perceptions about how comfortable team members feel in sharing their perspectives, and it has been found to positively impact team performance in samples outside of engineering. While prior research has indicated that psychological safety is positively related to team performance and outcomes, research related to psychological safety in engineering teams is less established. There is also a lack of comprehensive methodologies that capture the dynamic changes that occur throughout the design process and at each time point. In light of this, the goal of the current study was to understand how psychological safety might be measured practically and reliably in engineering student teams over time. In addition, we sought to identify factors that impact the building and waning of psychological safety in these teams over time. This was accomplished through a study with 260 engineering students in 68 teams in a first-year engineering design class. The psychological safety of the teams was captured for each team over five time points over the course of a semester long design project. The results of this study provide some of the first evidence on the reliability of psychological safety in engineering teams and offer insights as to how to support and improve psychological safety.
A Data-Driven Tip Flow Loss Prediction Method for a Transonic Fan Under Boundary Layer Ingesting Inflow Distortion
Authors: Yang Zhe , Lu Hanan , Pan Tianyu , Li Qiushi 
Published: September 2022

Abstract
In a boundary layer ingesting (BLI) propulsion system, the fan blades need to operate continuously under large-scale inflow distortion. The distortion will lead to serious aerodynamic losses in the fan, degrading the fan performance and the overall aerodynamic benefits of the aircraft. Therefore, in the preliminary design of a BLI propulsion system, it is necessary to evaluate the influence of the fuselage boundary layer under different flight conditions on the fan aerodynamic performance. However, a gap exists in the current computational methods for BLI fan performance evaluations. The full-annulus unsteady Reynolds-averaged Navier–Stokes (URANS) simulations can provide reliable predictions but are computationally expensive for design iterations. The low-order computational methods are cost-efficient but rely on the loss models for accurate prediction. The conventional empirical or physics-based loss models show notable limitations under complex distortion-induced off-design working conditions in a BLI fan, especially in the rotor tip region, compromising the reliability of the low-order computational methods. To balance the accuracy and cost of loss prediction, the paper proposes a data-driven tip flow loss prediction framework for a BLI fan. It employs a neural network to build a surrogate model to predict the tip flow loss at complex non-uniform aerodynamic conditions. Physical understandings of the flow features in the BLI fan are integrated into the data-driven modeling process, to further reduce the computational cost and improve the method’s applicability. The data-driven prediction method shows good accuracy in predicting the overall values and radial distributions of fan rotor tip flow loss under various BLI inflow distortion conditions. Not only does it have higher accuracy than the conventional physics-based loss models but also needs much less computational time than the full-annulus time-accurate simulations. The present work has demonstrated a significant potential of data-driven approaches in complex aerodynamic loss modeling and will contribute to future BLI fan design.
Robustness Analysis on Aerothermal Performance of the Winglet Squealer Tip—Part 1: Aerodynamic Performance
Authors: Huang Ming , Li Zhigang , Li Jun 
Published: September 2022

Abstract
Accurately assessing the robustness of the aerothermal performance of the blade tip is important considering that uncertainty is inevitable in the actual operation of turbines. However, the conventional uncertainty quantification methods are computationally inefficient for such an expensive black-box problem as turbine aerothermal performance prediction. In this paper, an efficient framework that is based on the combination of the sparse polynomial chaos expansion (PCE) and universal Kriging (UK) metamodel is applied to the uncertainty quantification of the effect of the conventional squealer tip and three different winglet squealer tips on the aerodynamic performance of the GE-E3 rotor blade tip. However, the inlet total pressure, inlet total temperature, and inlet flow angle are considered to flow condition uncertainty parameters and tip clearance is considered a geometrical uncertainty parameter. According to the results of the uncertainty quantification, in actual operation, although the setup of the winglet structure can still reduce the leakage flowrate, its effect will be much lower than predicted by deterministic calculations. The parameter that has the greatest influence on the uncertainty of the aerodynamic performance of the four tip structures is the tip clearance. Therefore, the geometric accuracy of the tip clearance should be strictly ensured in the turbine blade assembly and marching process. The uncertainty quantification calculations reveal that there is an antagonistic relationship between the pressure side cavity and suction side cavity on the aerodynamic performance uncertainty of the blade tip, which indicates a reasonable ratio of pressure side cavity and suction side cavity can make the fluctuation of the aerodynamic performance of the pressure side cavity vortex and suction side cavity vortex completely cancel, and thus design the winglet squealer tip with strong aerodynamic performance robustness.
Vortex Unsteadiness in the Endwall Region of a High-Lift Low-Pressure Turbine Passage

Published: September 2022

Abstract
Three-dimensional vortical structures within the endwall region of turbine passages directly affect the aerodynamic efficiency and heat transfer characteristics of the turbine. Interactions between the vortical endwall structures and the suction surface flow have been shown to be a significant source of loss generation through passages. One dominant vortex extends from the leading-edge junction region of the blade across the passage, where it interacts with the flow along the suction surface of the adjacent blade. In high-lift low-pressure turbine cascade passages, the vortical structure intermittently loses coherence and exhibits unsteady variations of strength and position as it extends across the passage. The present paper details the temporal behavior through high-speed measurements in a low-speed linear cascade of high-lift low-pressure turbine blades. Stereoscopic particle image velocimetry measurements in the passage are used to evaluate the unsteady behavior of the vortex. Space-time iso-surface plots of Q-criterion clearly show the evolution of the vortex over time. Analysis of the data reveals the various time scales of fluctuations in strength and position. Comparisons of the temporal fluctuations in the high-lift turbine passage are made with similar phenomena found in canonical junction flow papers in the literature. Key findings support the hypothesis that in-passage vortex unsteady characteristics near the endwall are influenced by leading-edge junction flow dynamics, and provide additional insight into the unsteady endwall flow physics that is necessary to further the development of endwall loss reduction techniques.
Use of Multiple Tracer Gases to Quantify Vane Trailing Edge Flow Into Turbine Rim Seals

Published: September 2022

Abstract
Overlapping features are commonly used as rim seals between stationary and rotating components in a turbine stage. These rim seals are used to prevent main gas path ingestion to the wheelspace cavity, which reduces the lifespan of critical engine components such as the turbine disk. In addition to the overlapping features, purge flow, diverted from the compressor, is injected into the rim cavity to act as an airflow sealing mechanism. Previous research identified that in addition to the purge flow in the rim cavity, cooling flow from the vane trailing edge (VTE) is ingested into the rim seal cavity carrying the potential to cool components in the wheelspace. These previous findings, however, were not able to distinctly separate purge from VTE cooling flows, which is the contribution of this paper based on uniquely using two different tracer gases. A one-stage test turbine operating at engine-relevant conditions and consisting of real engine hardware was used to validate and quantify the ingestion of the VTE flow by independently seeding the purge and VTE flows with two different tracer gases. Experimental results show the presence of VTE flow in the rim seal throughout all purge flowrates evaluated. Circumferential variation of VTE flow was also studied both experimentally and computationally using a computational fluid dynamics model. Results showed that ingested VTE flow can reduce the detrimental effect of hot gas ingestion particularly at higher purge flowrates.
Plume Model for Buoyancy-Induced Flow and Heat Transfer in Closed Rotating Cavities
Authors: Tang Hui , Owen J. Michael 
Published: September 2022

Abstract
The radial clearance between the rotating blades and stationary casing of a gas-turbine compressor depends on the radial growth of the rotating discs to which the blades are attached, and this growth depends on the buoyancy-induced flow and heat transfer in the air-filled cavities between adjacent discs. In some engines, the cavities are sealed, which creates a closed rotating cavity. A theoretical model has been developed to calculate the radial distribution of the temperature of the disc in a closed rotating cavity. The principal assumptions are that the convective heat transfer from the hot shroud to the cold hub of the cavity is via plumes of fluid in which the cold fluid moves radially outward, and the hot fluid inward, inside an inviscid quasi-axisymmetric core of rotating fluid. The fluid core is surrounded by boundary layers on all rotating surfaces, with free-convection layers on the surfaces of the shroud and hub and laminar Ekman layers on the surface of the discs. In addition to the convection, heat is transferred by one-dimensional radial conduction in the rotating discs. Using the model, equations have been derived to calculate the radial distribution of temperature in the discs and fluid core. These equations reveal that the non-dimensional temperatures for the disc and core, θd and θc, are controlled by three non-dimensional parameters: Reϕ, βΔT, and χ, the rotational Reynolds number, the buoyancy parameter, and the compressibility parameter, respectively. The compressibility parameter is defined as χ=defMa2/βΔT where Ma is a Mach number, and χ is shown to strongly affect the radial distribution of the core temperatures. There will be a critical value of χ at which the core temperature equals that of the heated shroud. For a closed cavity with adiabatic discs and xa = 0.5, the critical value is 6.7. Above this critical value, stratification is expected to occur and heat transfer from the shroud to the core will be by conduction rather than by convection. The theoretical model predicts radial distributions of temperatures in the discs and fluid core that are in good agreement with the experimentally derived values in a companion paper.
Comparison of Flame Describing Functions Measured in Single and Multiple Injector Configurations

Published: September 2022

Abstract
Recent investigations of combustion instabilities in annular systems indicate that considerable insights may be gained by using information gathered in single-sector experiments. Such experiments are, for example, employed to measure flame describing functions (FDFs), which represent the flame response to incident perturbations. These data may be used in combination with low-order models to interpret instabilities in multiple injector annular systems. It is known, however, that the structure and dynamical behavior of an isolated flame do not necessarily coincide with those of a flame placed in an annular environment with neighboring side flames. It is then worth analyzing effects that may be induced by the difference in lateral boundary conditions and specifically examining the extent to which the FDF data from single-sector experiments portrays the dynamical response of the flame in the annular environment. These issues are investigated with a new setup named TICCA-Spray, which comprises a linear arrangement of three injectors. The central flame is surrounded by two identical side flames in a rectangular geometry with key dimensions, sidewall separation, and spacing between injectors identical to those of the annular system MICCA-Spray. The describing function of the central flame is determined with techniques recently developed in single-sector experiments (SICCA-Spray). The FDFs obtained in the two configurations are compared for two swirler types having different swirl numbers and pressure drops. The effect of the swirl direction of the neighboring injectors is also explored by operating with co- and counter-swirl combinations. Differences between FDFs determined in the two test facilities, sometimes modest and in other cases less negligible, are found to depend on the flames' spatial extension and interactions. The general inference is that the FDFs measured in a single-injector combustor are better suited if the flame-wall interaction is weak, and provided that the area is equivalent to that of a single sector of an annular combustor. Nonetheless, using a multi-injector system would be more appropriate for a more precise FDF determination.
