Published: February 2024

AbstractNeighborhoods are one of the key determinants of health disparities among young people in the United States. While neighborhood deprivation can exacerbate health disparities, amenities such as quality parks and greenspace can support adolescent health. Existing conceptual frameworks of greening‐health largely focus on greenspace exposures, rather than greening interventions. In this paper, we develop and propose a Greening Theory of Change that explains how greening initiatives might affect adolescent health in deprived neighborhoods. The theory situates greening activities and possible mechanisms of change in the context of their ability to modify distal social determinants of health factors, stemming from macrostructural and historical processes that lead to resource inequalities, affecting both the social and built environment in which adolescents live and develop. The framework illustrates both short‐ and long‐term health, economic, and security effects of greening. We also describe how the theory informed the development of Project VITAL (Vacant lot Improvement to Transform Adolescent Lives) in Baltimore, MD, which aims to (1) build a citywide sharable database on vacant lot restoration activities, (2) evaluate the impact of greening initiatives on adolescent health outcomes, (3) conduct cost‐effectiveness analyses, and (4) develop best practices for greening programs for improved adolescent health.
Building blocks for a happy life: Longitudinal associations between early life income, mentorship and later well‐being

Published: February 2024

AbstractLongitudinal data from the Panel Study of Income Dynamics (PSID; N = 2996) were used to test hypotheses about the link between well‐being and financial and social developmental resources. Results suggest that higher average family income from birth to age 18, and personal and professional mentoring received between 17 and 30, were positively associated with indicators of positive well‐being and negatively related to negative indicators of well‐being. Interactions between early life family income and mentoring during emerging adulthood were not significant predictors of any of the well‐being outcomes. In all cases, the magnitudes of the coefficients became larger when simultaneously accounting for early life income, emerging adulthood mentoring, and their interactions—suggesting that financial and social resources in earlier life are independently linked to later life well‐being. Findings highlight that mentoring received in emerging adulthood benefits downstream hedonic and eudemonic well‐being, regardless of financial resources.

AbstractThe carbonate electrolyte chemistry is a primary determinant for the development of high‐voltage lithium metal batteries (LMBs). Unfortunately, their implementation is greatly plagued by sluggish electrode interfacial dynamics and insufficient electrolyte thermodynamic stability. Herein, lithium trifluoroacetate‐lithium nitrate (LiTFA−LiNO3) dual‐salt additive‐reinforced carbonate electrolyte (LTFAN) is proposed for stabilizing high‐voltage LMBs. We reveal that 1) the in situ generated inorganic‐rich electrode‐electrolyte interphase (EEI) enables rapid interfacial dynamics, 2) TFA− preferentially interacts with moisture over PF6− to strengthen the moisture tolerance of designed electrolyte, and 3) NO3− is found to be noticeably enriched at the cathode interface on charging, thus constructing Li+‐enriched, solvent‐coordinated, thermodynamically favorable electric double layer (EDL). The superior moisture tolerance of LTFAN and the thermodynamically stable EDL constructed at cathode interface play a decisive role in upgrading the compatibility of carbonate electrolyte with high‐voltage cathode. The LMBs with LTFAN realize 4.3 V‐NCM523/4.4 V‐NCM622 superior cycling reversibility and excellent rate capability, which is the leading level of documented records for carbonate electrode.

AbstractPhotocatalytic selective oxidation under visible light presents a promising approach for the sustainable transformation of biomass‐derived wastes. However, achieving both high conversion and excellent selectivity poses a significant challenge. In this study, two valuable trioses, glyceraldehyde and dihydroxyacetone, are produced from glycerol over Cuδ+‐decorated WO3 photocatalyst in the presence of H2O2. The photocatalyst exhibits a remarkable five‐fold increase in the conversion rate (3.81 mmol ⋅ g−1 ⋅ h−1) while maintaining a high selectivity towards two trioses (46.4 % to glyceraldehyde and 32.9 % to dihydroxyacetone). Through a comprehensive analysis involving X‐ray photoelectron spectroscopy measurements with and without light irradiation, electron spin resonance spectroscopy, and isotopic analysis, the critical role of Cu+ species has been explored as efficient hole acceptors. These species facilitate charge transfer, promoting glycerol oxidation by photoholes, followed by coupling with OH‐, which are subsequently dehydrated to yield the desired glyceraldehyde and dihydroxyacetone.

Published: February 2024

AbstractFunctional imaging (FI) techniques have revolutionized tumor imaging by providing information on specific tumor functions, such as glycometabolism. However, tumor cells lack unique molecular characteristics at the molecular level and metabolic pathways, resulting in limited metabolic differences compared to normal cells and increased background signals from FI. To address this limitation, we developed a novel imaging technique termed proximity‐enhanced functional imaging (PEFI) for accurate visualization of tumors. By using “two adjacent chemically labeled glycoproteins” as output signals, we significantly enhance the metabolic differences between tumor and normal cells by PEFI, thereby reducing the background signals for analysis and improving the accuracy of tumor functional imaging. Our results demonstrate that PEFI can accurately identify tumors at the cellular, tissue, and animal level, and has potential value in clinical identification and analysis of tumor cells and tissues, as well as in the guidance of clinical tumor resection surgery.

Abstract[Cu(5‐ClSal‐Trp)(bpy)]·CH3OH (1) and [Cu(3,5‐ClSal‐Trp)(bpy)]·H2O (2) (5‐ClSal‐Trp: Schiff base derived from 5‐chlorosalicylaldehyde and tryptophan, 3,5‐ClSal‐Trp: Schiff base derived from 3,5‐dichlorosalicylaldehyde and tryptophan, bpy: 2,2′‐bipyridine) have been synthesized and analyzed by CHN analysis, FTIR, electronic absorption spectroscopy, ESI‐MS and XRD techniques. Interaction of the complexes with biomolecules {calf thymus DNA (CT‐DNA) and bovine serum albumin (BSA)} has been researched by fluorescence and electronic absorption spectroscopy. The results show that the complexes can bind via a moderate intercalation binding mode. According to the results obtained with both methods, the logKb and logKSV values of the complexes were found to be very close to each other. BSA quenching mechanism was found to be static. The results showed that the interaction between the complexes and BSA is driven by the hydrogen bond and van der Waals interaction. Additionally, the r values of the complexes (the complex 1 = 0.59 nm and the complex 2 = 0.53 nm) calculated from FRET theory suggested that the distance between the complexes (acceptor) and BSA (donor) is quite close. The complexes exhibited free radical scavenging activity compared to the standard antioxidant β‐carotene and catechin. Antiproliferative efficiency of the complexes on both breast cancer cells (MCF‐7 and MDA‐MB‐231) were also researched using the Sulforhodamine B (SRB) viability assay. It was found that the complex 1 (IC50 = 10.99 μM) exhibited higher cytotoxicity than cisplatin (IC50 = 15.6 μM) against MDA‐MB‐231 cell line. Additionally, intracellular reactive oxygen species (ROS) formation was determined by dihydroethidium (DHE) fluorescent staining. N‐acetylcysteine (NAC) was used as an efficient reactive oxygen species (ROS) scavenger. It was observed that newly synthesized Cu (II) complexes exhibited anti‐growth potential in human breast cancer cells. Additionally, it was determined that the complexes induced reactive oxygen species (ROS) formation in cells in a dose‐dependent manner.

Published: February 2024

AbstractThe molecular structure of a crystalline monolayer of hydrocarbon chains was modeled and studied via computer simulation using the Metropolis Monte Carlo algorithm at a temperature T = 300 K. The only interactions in this system occur through Lennard‐Jones dispersion forces and short‐range atom‐atom repulsion. The intent was to establish whether the chains were either rigidly extended or twisted via the thermal formation of gauche bonds and apply the results to understand observations made on two possible oleogelators: triacontane and stearic acid. Specifically, we aimed to understand if their observed crystalline monolayer thicknesses are due to gauche‐bond‐shortened hydrocarbon chains oriented perpendicular to the monolayer surface, or to fully extended rigid chains oriented at a tilt angle with respect to the surface. The results showed that crystals of hydrocarbon chains did not include significant gauche bonds, so that all molecules were rigidly extended, thus explaining the experimental data previously reported. Accordingly, TC and SA dimer molecules are packed in crystalline multilayers with tilt angles in relation to the methyl group plane.

AbstractIt is of great importance to enhance ability of charring formation for polystyrene (PS) to overcome non‐charring feature during burning. Here, we demonstrate a kind of ternary intumescent flame retardant composition composed by a novel ionic liquid butyltriphenylphosphonium‐chelated orthoborates (IL) with self‐expanded flame retardant, ammonium polyphosphate (APP) and expandable graphite (EG), to improve flame retardancy of PS. This ternary composition promotes limited oxygen index (LOI) value to 26.6 ± 0.5% and UL‐94 V0 level for PS composite with 15 wt% total loading. In addition, the peak value of heat release rate and smoke production rate of PS composite with ternary composition are separately reduced by 79.7% and 70.7% comparing to neat PS as well as 44.4% and 29.2% to its IL‐free binary counterpart in cone calorimeter test. Meanwhile, the ternary composition displays compact charring bulk constructed by large‐expansion‐volume vermiform expanded graphite. The TG‐FTIR technique is used to analyze gaseous profiles. The rheological property discloses that expansion behavior of the ternary composition contributes to robust viscoelasticity of composite and advantageous network construction at high temperature. Given the fire performance of the ternary composition, the combination of IFR and IL provides an opportunity for rational design and fabrication of functional flame‐retardant system.

AbstractAn unprecedented meglumine‐based three‐component deep eutectic solvent (3c‐DES) (MegPAc) was synthesized using meglumine, p‐toluenesulfonic acid (PTSA), and acetic acid as a renewable, and non‐toxic solvent. The exploitation of the MegPAc as an eco‐friendly reaction media to construct a selective and sensitive small organic molecular sensing probe, namely, pyrazolo[5,1‐b]quinazoline‐3‐carboxylates (PQCs) was executed. Captivatingly, the MegPAc served the dual role of solvent and catalyst, and it delivered the title components with 69–94 % yields within 67–150 minutes. Furthermore, a UV‐visible study unfolds the selective detection of Cu2+ ions with our synthetic probe 4 ba and resulted in hypsochromic shift due to electrostatic interactions. Additionally, 1H NMR titration study and density functional theory (DFT) calculations were performed to attest the binding mechanism of sensing probe 4 ba and Cu2+ ions. Worthy of mention, this protocol unveils the efficacy of meglumine‐based 3c‐DES for the first time as a bio‐renewable system to synthesize the PQCs.
State‐dependent indirect hp‐pseudospectral method for rigid spacecraft attitude optimal control problem
Authors: Liu Yuxian , Li Yan 
Published: February 2024

AbstractThe state‐dependent indirect ‐pseudospectral (SDIHP) method for rigid spacecraft attitude control is presented in this paper. The optimal controller is obtained by the SDIHP method through classifying the attitude optimal control problem as a nonlinear quadratic optimal control problem. In the proposed control scheme, successive state‐dependent coefficient (SDC) parameterization is initially applied to the spacecraft dynamics to derive an available linear system to decrease the calculation cost and speed. Then, the indirect ‐adaptive spectral discretization is developed to convert the resultant optimal control problem into a sequence of linear equations, which can improve the global computational efficiency and guarantee the solving precision. Hence, the optimal control can be efficiently solved using basic matrix operations under the necessary collocation points based on the ‐adaptive features. Considering the inertia uncertainties and external disturbances, a state feedback controller is generated by the receding horizon control (RHC) framework to improve the robustness. Simulation results are included to show the effectiveness and performance of the suggested optimal method.
Transfer reinforcement learning for multi‐agent pursuit‐evasion differential game with obstacles in a continuous environment
Authors: Hu Penglin , Pan Quan , Zhao Chunhui , Guo Yaning 
Published: February 2024

AbstractIn this paper, we study the multi‐pursuer single‐evader pursuit‐evasion (MSPE) differential game in a continuous environment with the consideration of obstacles. We propose a novel pursuit‐evasion algorithm based on reinforcement learning and transfer learning. In the source task learning stage, we employ the Q‐learning and value function approximation method to overcome the challenges posed by the large‐scale storage space required by the conventional Q‐table solution method. This approach expands the discrete space to the continuous space by value function approximation and effectively reduces the demand for storage space. During the target task learning stage, we utilize the Gaussian mixture model (GMM) to classify the source tasks. The source policies whose corresponding state‐value sets have the highest probability densities are assigned for the agent in the target task for learning. This methodology not only effectively avoids negative transfer but also enhances the algorithm's generalization ability and convergence speed. Through simulation and experiment, we demonstrate the algorithm's effectiveness.
Studies of bright flat‐spectrum radio quasar 3C 454.3 at high and very‐high‐energies

Published: February 2024

AbstractBlazars are the subclass of active galactic nuclei (AGNs) which includes the Flat Spectrum Radio Quasars (FSRQ) and BL Lacertae (BL Lac) objects. Variability on the short‐ and long‐time scale in all the wide energy ranges from radio up to gamma‐ray emission is a special characteristic of blazars. Multi‐wavelength studies of the flaring activity and variability of blazars can serve as a tool to probe the physical properties of the near the core regions and processes responsible for the observed features. 3C 454.3 is a bright FSRQ that is intensively studied through the wide range of electromagnetic spectrum. It has shown remarkably high activity since 2000. The long‐term observations of 3C 454.3 at 800 GeV–100 TeV energies with the SHALON telescope were started in 1998 year. A number of activity periods were found. The most significant flaring state of 3C 454.3 at TeV energies was detected in the SHALON observational period of November–December 2010. This increase is correlated with the flares at a lower energy range in observations of Fermi‐LAT. The direct association of the significant changes of gamma‐ray flux with strong core radio flares are not clear but observed correlations and lags in multi‐wavelength activity may point to the complexity of the emission processes in blazars connected with disturbance propagating in the jet.

AbstractThe investigation of very high energy gamma‐ray sources touches on the problem of the cosmic ray origin and the role of the Galaxy in their generation. The SHALON observations have yielded the results on Cygni SNR Galactic supernova remnant. The observation results are presented with spectral energy distribution and emission map by SHALON in comparison with other experiment data obtained by ROSAT in x‐ray energy range, radio‐data by CGPS, and also observations of GeV–TeV gamma‐rays by Fermi LAT. The overall Cygni SNR characteristics detected in radio, x‐rays, and GeV–TeV gamma‐rays can be a result of the shocks at the interaction of the supernova ejecta and the surrounding medium. The collected experimental data help to make clear the origin of TeV ‐ray emission in the Cygni SNR. The density of target material in the SNR surroundings is enough to produce the observable TeV gamma‐ray flux via the shock acceleration of hadrons in the detected regions. The detection of gamma‐ray emission at 0.8–60 TeV from the North‐West and South‐East shells of Cygni SNR by SHALON would favor the hadronic origin of the gamma‐rays in this supernova remnant.

Published: February 2024

AbstractThe renal tubular organic cation transporter 2 (OCT2) and multidrug and toxin extrusion protein 1 (MATE1) mediate the vectorial elimination of many drugs and toxins from the kidney, and endogenous biomarkers for vectorial transport (OCT2‐MATE1) would allow more accurate drug dosing and help to characterize drug–drug interactions and toxicity. Human serum uptake in OCT2‐overexpressing cells and metabolomics analysis were carried out. Potential biomarkers were verified in vitro and in vivo. The specificity of biomarkers was validated in renal transporter overexpressing cells and the sensitivity was investigated by Km. The results showed that the uptake of thiamine, histamine, and 5‐hydroxytryptamine was significantly increased in OCT2‐overexpressing cells. In vitro assays confirmed that thiamine, histamine, and 5‐hydroxytryptamine were substrates of both OCT2 and MATE1. In vivo measurements indicated that the serum thiamine level was increased significantly in the presence of the rOCT2 inhibitor cimetidine, and the level in renal tissue was increased significantly by the rMATE1 inhibitor pyrimethamine. There were no significant changes in the uptake or efflux of thiamine in cell lines overexpressed OAT1, OAT2, OAT3, MRP4, organic anion transporting polypeptide 4C1, P‐gp, peptide transporter 2, urate transporter 1, and OAT4. The Km for thiamine with OCT2 and MATE1 were 71.2 and 10.8 μM, respectively. In addition, the cumulative excretion of thiamine at 2 and 4 h was strongly correlated with metformin excretion (R2 > 0.6). Thus, thiamine is preferentially secreted by the OCT2 and MATE1 in renal tubules and can provide a reference value for evaluating the function of the renal tubular OCT2‐MATE1.
