AbstractAimThe three‐phase enriched environment (EE) intervention paradigm has been shown to improve learning and memory function after cerebral ischemia, but the neuronal mechanisms are still unclear. This study aimed to investigate the hippocampal–cortical connectivity and the metabolic interactions between neurons and astrocytes to elucidate the underlying mechanisms of EE‐induced memory improvement after stroke.MethodsRats were subjected to permanent middle cerebral artery occlusion (pMCAO) or sham surgery and housed in standard environment or EE for 30 days. Memory function was examined by Morris water maze (MWM) test. Magnetic resonance imaging (MRI) was conducted to detect the structural and functional changes. [18F]‐fluorodeoxyglucose (FDG) positron emission tomography (PET) was conducted to detect brain energy metabolism. PET‐based brain connectivity and network analysis was performed to study the changes of hippocampal–cortical connectivity. Astrocyte‐neuron metabolic coupling, including gap junction protein connexin 43 (Cx43), glucose transporters (GLUTs), and monocarboxylate transporters (MCTs), was detected by histological studies.ResultsOur results showed EE promoted memory function improvement, protected structure integrity, and benefited energy metabolism after stroke. More importantly, EE intervention significantly increased functional connectivity between the hippocampus and peri‐hippocampal cortical regions, and specifically regulated the level of Cx43, GLUTs and MCTs in the hippocampus and cortex.ConclusionsOur results revealed the three‐phase enriched environment paradigm enhanced hippocampal–cortical connectivity plasticity and ameliorated post‐stroke memory deficits. These findings might provide some new clues for the development of EE and thus facilitate the clinical transformation of EE.
Subjectively preferred octave size is resolved at the late stages of cerebral auditory processing

Published: September 2023

AbstractHuman listeners prefer octave intervals slightly above the exact 2:1 frequency ratio. To study the neural underpinnings of this subjective preference, called the octave enlargement phenomenon, we compared neural responses between exact, slightly enlarged, oversized, and compressed octaves (or their multiples). The first experiment (n = 20) focused on the N1 and P2 event‐related potentials (ERPs) elicited in EEG 50–250 ms after the second tone onset during passive listening of one‐octave intervals. In the second experiment (n = 20) applying four‐octave intervals, musician participants actively rated the different octave types as ‘low’, ‘good’ and ‘high’. The preferred slightly enlarged octave was individually determined prior to the second experiment. In both experiments, N1‐P2 peak‐to‐peak amplitudes attenuated for the exact and slightly enlarged octave intervals compared with compressed and oversized intervals, suggesting overlapping neural representations of tones an octave (or its multiples) apart. While there were no differences between the N1‐P2 amplitudes to the exact and preferred enlarged octaves, ERP amplitudes differed after 500 ms from onset of the second tone of the pair. In the multivariate pattern analysis (MVPA) of the second experiment, the different octave types were distinguishable (spatial classification across electroencephalography [EEG] channels) 200 ms after second tone onset. Temporal classification within channels suggested two separate discrimination processes peaking around 300 and 700 ms. These findings appear to be related to active listening, as no multivariate results were found in the first, passive listening experiment. The present results suggest that the subjectively preferred octave size is resolved at the late stages of auditory processing.
Complementarity analysis of a multi‐item inventory model with leading product pricing
Authors: Kim Sangjo , Feng Youyi , Xu Jianjun 
Published: September 2023

Our research investigates a joint inventory replenishment and pricing problem, where a seller controls the price of a leading product while restocking for all the products. We demonstrate that the seller's expected value functions present an [Formula: see text] structure, recommending an optimal order‐up‐to inventory‐level and list‐price policy. Our findings reveal divergent economic relationships between products from the seller's and customer's perspectives, suggesting managers broaden their strategies beyond customer viewpoints. We extend the pricing and inventory analysis to scenarios involving three substitute products under both price and inventory control. In these situations, we further reveal that sellers and customers uniformly view product inventories as substitutes, and the corresponding value functions are submodular and mutually diagonally dominant.

Published: September 2023

AbstractIntroductionWe investigated whether the Death/Suicide Implicit Association Test (D/S‐IAT) predicted suicidal ideation (SI) in psychiatric inpatients.MethodsOne hundred eighty veterans admitted for either SI or suicidal behavior (SB) (the primary sample) (N = 90) or alcohol detoxification (N = 90) completed the D/S‐IAT and scales measuring SI. Correlation and regression coefficients were measured between the D/S‐IAT (as a full‐scale or dichotomized score [D > 0]) and self‐reported current or imminent SI (over the next 1–3 days).ResultsIn the primary sample, the full‐scale D/S‐IAT was significantly correlated with the intensity of current SI (r = 0.22, p = 0.04) and especially with wishes to be dead (r = 0.35, p < 0.001). The intensity of imminent SI was significantly predicted by the full‐scale (p = 0.02) and dichotomized D/S‐IAT score (p = 0.05) in a multiple regression model. However, no significant associations were observed when both the D/S‐IAT score and current (present/absent) or imminent SI (occurred/did not occur) were dichotomous measures. In participants receiving alcohol detoxification, the D/S‐IAT significantly predicted only wishes to be dead (r = 0.33, p < 0.001).ConclusionThe full‐scale D/S‐IAT score predicted the current intensity of wishes to be dead in both inpatient samples, and current and imminent SI in participants admitted for SI/SB. The dichotomized D/S‐IAT score did not predict the simple occurrence of SI.
Must religious nationalism divide? Race, government‐supported religion, and views of political solidarity and compromise
Authors: Perry Samuel L. , McDaniel Eric L. 
Published: September 2023

AbstractBackgroundAmericans who believe government policies should bolster religion's influence tend to favor rigid in‐group/out‐group distinctions and hierarchies. Yet given that religious and political views are fundamentally racialized, we theorize racial identity moderates the link between favoring government‐supported religion and views toward political solidarity and compromise.ObjectiveThis study extends our understanding of how beliefs about religion and politics involve not only different, but contradictory orientations to political solidarity and compromise contingent on racial identity.MethodsWe estimate binary logistic regression models using data from Pew Research Center's American Trends Panel, Wave 92, a nationally representative survey of over 9200 Americans.ResultsMain effects indicate that favoring government‐supported religion is associated with rejecting political compromise, but unassociated with measures of solidarity. Interactions, however, show main‐effects mask considerable racial variation. Substantively, the link between favoring government‐supported religion and rejecting political compromise is limited to White Americans. Yet Black Americans who favor government‐supported religion become significantly more likely to recognize shared values despite political differences and Black Americans who favor government‐supported religion see less difference between Democrats and Republicans, while their White counterparts see more.ConclusionsFavorability toward government policies supporting religion does not necessarily represent “us versus them” orientations. Rather, the association is racially contingent.

AbstractObjectiveTo describe the surgical treatment, postoperative management, and outcome of a miniature horse undergoing total hip arthroplasty (THA).Study designCase report.AnimalsA 4‐year‐old miniature horse stallion weighing 85 kg.MethodsThe horse presented with left coxofemoral luxation of ~6 weeks duration. Computed tomography confirmed craniodorsal luxation with marked degenerative changes to the femoral head. The horse underwent THA using cementless press fit implants, including an interlocking lateral bolt for the femoral stem.ResultsThe horse recovered well from anesthesia but suffered a coma‐like episode after returning to a stable. Following treatment of presumed hypovolemia, the horse regained normal mentation and was discharged 24 days after surgery. At reassessment 12 weeks postoperatively, the horse was 2/10 left hind limb lameness at trot with good healing of the surgery site. Five months postoperatively mild (1/10) lameness remained at trot but the horse was able to canter normally on both reins. The horse has since been managed normally with no veterinary treatment required for 32 months postoperatively.ConclusionTotal hip arthroplasty is possible in miniature horses weighing up to 85 kg and can result in a good long‐term outcome.

Published: September 2023

Abstract
Objective: This study characterizes three commercially available wearable respiratory monitors (WRMs): (1) Hexoskin Smart Garment, (2) Smartex WWS, and (3) Equivital EQ02 LifeMonitor, each with a unique chest motion sensor technology: respiratory inductance plethysmography, piezoresistor, and strain gauge, respectively. WRMs comprise of a body garment with embedded sensors that measure ambulatory chest motion in real-time. Once calibrated, chest motion waveforms from WRMs can be converted to lung volume waveform, which is then used to derive respiratory topography. The aim of this study is to assess and compare these WRMs in terms of: (i) their response signal to chest motion linearity, which is necessary for successful calibration, and (ii) their ability to measure breath-hold, which is a parameter of interest for lung deposition modeling. Methods: A benchtop test setup was built to simulate chest motion in a controlled way to facilitate comparison across the three devices. A staircase square-wave chest motion profile was used to simultaneously assess both signal linearity and ability to measure breath-hold. The respiratory response from the sensors was compared to the simulated chest motion. Results: The Hexoskin showed the best performance in both metrics, whereas the Equivital had the worst performance in both. The Smartex showed moderate ability to measure breath-hold but poor signal linearity. Conclusion: Of the three WRMs tested, the Hexoskin appears to be the best choice for ambulatory lung volume measurement. Significance: This study demonstrates the feasibility of adapting current technology to observe respiratory behavior valuable in many research domains, including tobacco research.
Cellular Inorganic Ceramic for Highly Efficient Daytime Passive Radiative Cooling

Abstract
Traditional compression-based cooling systems consume great amounts of energy, causing adverse impacts on the environment by releasing heat and ozone-depleting pollutants. Daytime passive radiative cooling is regarded as an eco-friendly alternative to generate cooling without electricity and coolants. In order to achieve continuous and effective cooling, the cooler requires high solar reflection as well as strong mid infrared emission. However, it remains a great challenge to realize cooling effect in the daytime. Sunlight is an intensive heat source in the daytime, especially during noontime. Under sunlight, even absorption of a few percent of solar irradiation can easily compensate for the thermal heat dissipated by thermal radiation, and therefore fail to achieve any cooling effect. Here we develop a cellular inorganic radiative cooler in the format of ceramic, which possesses advanced optical properties for radiation cooling while exhibiting great outdoor applicability. The cellular ceramic possesses a hierarchically porous structure, which results in efficient light scattering across the whole solar spectrum. The average solar reflection of the cellular ceramic reached a recorded-high of 99.6% with porosity of 70% and thickness of around 600 μm. With the near-ideal solar reflection and high thermal emission (96%), the cellular ceramic can theoretically obtain cooling power in excess of 140 W/m2 under 1000 W/m2 solar intensity in favorable application conditions. Moreover, the high bond strength and chemical inertness of alumina protect the cellular ceramic from the adverse effect of UV exposure, which is desired for long-term outdoor applications. The outstanding performance of cellular ceramic surpasses that of current daytime radiative coolers. The facile fabrication and promising applicability of cellular ceramic exhibits great potential for large-scale applications, such as buildings, to saving the energy for indoor thermal regulation.
Hydrogel-Coated Mesh for High-Efficiency, Ultra-Fast Oil-Water Separation

Published: September 2023

Abstract
Fast and efficient oil-water separation is critical to resolving industrial wastewater, environmental protection, and oil spills. With the demand for oil continuing to grow and the global oil reserves being limited in supply, it becomes more important to be able to recover as much oil as possible. In this paper, a reinforced membrane made using a polyacrylamide (PAM) hydrogel solution was used to coat different copper mesh samples that have a variety of pore sizes. The wetting properties of membranes are characterized by the contact angle (CA) measurements, the permeability of bulk fluids, and the surface morphologies of the mesh before and after coating. Using a contact angle goniometer, it was found that the static underwater oil CA showed to be over 90° while the oil CA in air resulted in an angle below 15°. Since the oil CA in the air is less than the oil CA underwater, we can imply that the PAM hydrogel-coated mesh samples are superhydrophilic in the method of using an air-solid-liquid three-phase system. As the mesh pore size increases, the oil CA also increases. The difference in weight during the swelling period becomes larger with increasing mesh pore size up to approximately 2880 minutes. With the use of a long working distance microscope, it was found a uniform hydrogel coating resulted in smaller pore size and a rougher surface. It was found that the coated mesh after testing has less binding at the mesh joints compared to the coated mesh before testing. From this, it can be indicated that high swelling rates result from large aggregation near the mesh joints.
Design Methodology of a Concentrating Solar Volumetric Receiver
Authors: Akba Tufan , Baker Derek , Mengüç M. Pınar 
Published: September 2023

Abstract
A volumetric receiver design process is proposed to respond wide range of power, outlet temperature, or mass flow rate needs. In the receiver model, concentrated solar radiation hits the inner surface cavity and heats the gaseous fluid passing through the porous media assembled between the cavity and the insulator. Porous media properties and receiver geometry are coupled in the design process to determine the best possible option. A two-step process starts with a parameter sweep to create a surrogate model. Then, gradient-based design optimization is performed using two different surrogate models to maximize the outlet air temperature for bounded design variables in receiver volume and outer surface temperature constraints.
The proposed design process has the advantage of exploring more design options faster using the surrogate model and more accurate results using the base model in the plant-level simulations. The methodology is discussed by comparing the surrogate models and the model validation shows that over 95% accuracy is obtained using both surrogate models. Surrogate-based design optimization is compared as in solution time and the final results are compared with respect to the base receiver model.
Thermodynamic Performance Investigation of Environmentally Friendly Working Fluids in a Geothermal Integrated Pumped Thermal Energy Storage System
Authors: Mwesigye Aggrey 
Published: September 2023

Abstract
Among the available energy storage technologies, pumped thermal energy storage (PTES) is emerging as a potential solution for large-scale electrical energy storage with no geographical limitations and high roundtrip efficiencies. However, PTES requires a low-cost high temperature heat source to achieve reasonable roundtrip efficiencies. Moreover, organic Rankine cycle-based PTES systems require high performance and environmentally friendly working fluids. In this study, the thermodynamic performance of a geothermal integrated PTES system using environmentally friendly working fluids is investigated. The mathematical model of the geothermal integrated PTES system is developed using the first and second laws of thermodynamics and implemented in Engineering Equation Solver (EES). With the developed model, the thermodynamic performance of the PTES system for different working fluids, including Butene, cyclopentane, iso-butane, R1233zd(E), R1234ze(Z), R1224yd(Z), HFO1336-mzz(Z), R365mfc, n-hexane, and n-pentane was investigated. For geothermal fluid outlet temperatures between 60°C and 120°C and geothermal fluid inlet and outlet temperature differences across the evaporator between 20°C and 60°C, the net power ratio i.e., the ratio of the electrical energy discharged to the electrical energy used to run the charging cycle is between 0.25 and 1.40. This shows that the system has the potential to give back more than 100% of the electrical energy used during charging under certain conditions. High net power ratios are obtained for a combination of high source temperatures and low geothermal fluid inlet and outlet temperature differences.
Stability Assessment of High Temperature Coatings for Flux Measurement Applications
Authors: McLaughlin Luke P. , Laubscher Hendrik , Konings Jörgen 
Published: September 2023

Abstract
This study investigated the durability of four high temperature coatings for use as a Gardon gauge foil coating. Failure modes and effects analysis have identified Gardon gauge foil coating as a critical component for the development of a robust flux gauge for high intensity flux measurements. Degradation of coating optical properties and physical condition alters flux gauge sensitivity, resulting in flux measurement errors. In this paper, four coatings were exposed to solar and thermal cycles to simulate real-world aging. Solar simulator and box furnace facilities at the National Solar Thermal Test Facility (NSTTF) were utilized in separate test campaigns. Coating absorptance and emissivity properties were measured and combined into a figure of merit (FOM) to characterize the optical property stability of each coating, and physical coating degradation was assessed qualitatively using microscope images. Results suggest rapid high temperature cycling did not significantly impact coating optical properties and physical state. In contrast, prolonged exposure of coatings to high temperatures degraded coating optical properties and physical state. Coatings degraded after 1 hour of exposure at temperatures above 400 °C and stabilized after 6–24 hours of exposure. It is concluded that the combination of high temperatures and prolonged exposure provide the energy necessary to sustain coating surface reactions and alter optical and physical coating properties. Results also suggest flux gauge foil coatings could benefit from long duration high temperature curing (&gt; 400 °C) prior to sensor calibration to stabilize coating properties and increase measurement reliability in high flux and high temperature applications.

Published: September 2023

Abstract
The energy demands from data centers contribute greatly to water scarcity footprint and carbon emissions. Understanding the use of on-site renewable power generation is an important step to gaining insight into making data centers more sustainable. This study examines the impact of on-site solar or wind energy on water scarcity usage effectiveness (WSUE) and carbon usage effectiveness (CUE) at a U.S. county scale for a given data center size, water consumption level, and energy efficiency. The analysis uncovers combinations of specific metrics associated with the grid-based carbon emissions and water scarcity footprint that enable predictions of the improvements anticipated when implementing on-site solar or wind energy. The implementation of on-site renewables has the most benefit on reducing carbon footprint in areas with high existing grid-based emissions such as the mountain regions and the western side of the Appalachian Mountains. The largest benefit in reducing water scarcity footprint is generally seen in the western U.S.

Published: September 2023

Abstract
This paper aims to assess the receiver efficiency, maximum surface temperature, and pressure drop through a ∼10 MW thermal solar receiver designed to heat carbon dioxide from 550 to 720°C at 20 MPa. The solar receiver is comprised of 400 identical unit-cells fabricated using additive manufacturing. Each unit-cell contains an array of micro-pins with a single inlet and outlet for carbon dioxide. A unit-cell thermal hydraulic submodel developed in prior work is integrated into a multiple unit-cell receiver model, which solves for the mass flow rate, outlet temperature, maximum surface temperature, efficiency, pressure drop, and other parameters of each unit-cell and the overall receiver for a specified solar flux distribution. Simulations are conducted for a scenario in which the overall outlet temperature is fixed, and the pressure drop through each parallel unit cell is the same. The results suggest that overall receiver efficiency for the parallel unit-cell approach can be optimized using different unit-cell geometries throughout the receiver.
