Published: January 2025

ABSTRACTGuided by density functional theory (DFT), four benzothiadiazole based bifunctional monomers with varying electronic properties and geometric sizes have been designed. Utilizing tri(4‐ethynylphenyl)amine (TEA) as a multifunctional monomer, with temperature control, four TEA‐based conjugated microporous polymers (CMPs) TEA‐BT1‐TEA‐BT4 have been synthesized by Sonogashira Hagihara coupling polymerization. The electronic and geometric effects of the bifunctional monomers on the photocatalytic water splitting hydrogen evolution of TEA based CMPs have been investigated in detail. It shows that as the electron donating ability of the bifunctional monomers increases, the thermal stability enhances and the bandgap increases while the specific surface area and hydrogen evolution performance remain relatively unchanged. As the geometric area increases, the thermal stability decreases, the bandgap increases, the specific surface area and hydrogen evolution performance decreases seriously. All four polymers exhibit excellent thermal stability and stable photocatalytic water splitting hydrogen evolution properties. Without the presence of a cocatalyst, TEA‐BT1 gives the highest hydrogen evolution efficiency(115.74 μmol g−1 h−1). This research suggests that TEA is a novel and excellent multifunctional block for CMPs based photocatalysts, above all, it provides a new method to optimize CMPs properties to design high efficiency photocatalysts.

Published: January 2025

AbstractIn this paper, we examine the regulation performance of single‐input single‐output networked control systems (NCSs). Network limitations such as time delay, noise, and insufficient bandwidth significantly challenge the regulation performance of NCSs. We derive the regulation performance limits under dual‐channel Gaussian noise, encoding–decoding processes, and bandwidth constraints using coprime factorization and spectral techniques. Our findings reveal that the regulation performance of NCSs is closely associated with the nonminimum phase zeros, unstable poles, and the communication constraints of the network. We also present a numerical simulation to validate our findings.
Generous Returners, Vanishing Refunds: How Consumers Spend Monetary Refunds of Returns
Authors: Jami Ata 
Published: January 2025

ABSTRACTFor every $100 spent on retail industry, consumers on average return $14.50 value of products to retailers, and they receive the amount they originally paid as a refund. The refund money is fungible, and it can be freely spent on other items or be saved. This research examines consumers' propensity to spend return refunds and the types of products they purchase with return refunds. Across 10 studies (N = 2710), I show that people are more likely to make a purchase and to purchase hedonic products when they are spending return refunds versus money typically used for purchases. Examining the psychological mechanism underlying this effect, I show that consumers are more likely to spend return refunds because they perceive a lower psychological loss and experience less pain of paying when spending refund money than when spending other regularly available monetary sources. Hence, receiving return refunds has a stronger effect on the spending behavior of people who chronically experience an intense pain of paying (i.e., “tightwads”) than those who experience less pain (i.e., “spendthrifts”). Moreover, this research shows that neither payment depreciation nor the perception of a return refund as a windfall fully explain how people choose to spend it. In sum, individuals have a different psychological experience when they spend return refunds versus other conventional monetary sources.

Comprehensive SummaryPhotothermal hydrogenation of carbon monoxide (CO) holds the potential to generate valuable C2+ chemicals using renewable solar energy. However, its activity and selectivity towards C2—C3 alkanes are limited compared to conventional thermal catalysis. In this study, we developed a robust catalyst consisting of Cu/Fe3O4 nanoparticles on Mo2CTx MXene, showing enhanced photothermal C2—C3 production. The Cu component plays a crucial role in H2 dissociation and subsequent H spillover, facilitating the in situ generation of Fe0 in Fe5C2 active sites and thus efficiently promoting photothermal CO hydrogenation. As a result, we achieved a 51.3% C2+ selectivity and 78.5% CO conversion at a high gas hourly space velocity (GHSV) of 12000 mL·gcat−1·h−1 and 2.5 MPa in a flow reactor at 320 °C. The overall C2—C3 yield reached 23.6% with Cu/Fe3O4/Mo2CTx catalysts, marking a 2.8‐fold increase compared to the performance of the bare Fe3O4/Mo2CTx catalyst.

ABSTRACTAchieving successful cross‐media color reproduction is very important in image processing. The purpose of this study is to accumulate high dynamic range data to verify and modify the CAM16‐UCS model. There are two experiments in this study. The first experiment was aimed to collect corresponding data of color patches between colors on a display and the real scene viewed under high dynamic range viewing conditions. The results were used to refine CAM16‐UCS model. Six illumination levels (i.e., 15, 100, 1000, 3160, 10 000, and 32 000 lx) and 13 test color samples were used in the experiment. Ten observers adjusted the color patches on the display to match the color samples of the real scene. The visual results showed a clear trend, an increase in the illumination level raised vividness perception (both increase in lightness and colorfulness). However, CAM16‐UCS did not give accurate prediction to the visual results, especially in the lightness direction. The model was then refined to achieve satisfactory performance and to truthfully reflect the visual phenomena. However, the effect of the modified model could not achieve successful color image reproduction, especially under low illumination conditions. Experiment 2 was conducted by adjusting the overall lightness and colorfulness of the image. The results were used to extend the model for image reproduction. Also, an independent experiment verified that the image generated by the new model matched the real environment well, indicating that the model can perform well in scene restoration.

AbstractAimsThe study aims to examine characteristics and outcomes associated with health‐related quality of life (HRQoL) in patients with heart failure (HF) with preserved, mildly reduced and reduced ejection fraction (EF) (HFpEF, HFmrEF and HFrEF).Methods and resultsData on HRQoL were collected in the Swedish Heart Failure Registry (SwedeHF; 2000–2021) using the EuroQoL 5‐dimensional visual analogue scale (EQ 5D‐vas). Baseline EQ 5D‐vas scores were categorized as ‘best’ (76–100), ‘good’ (51–75), ‘bad’ (26–50) and ‘worst’ (0–25). Independent associations between patients' characteristics and EQ 5D‐vas, as well as between EQ 5D‐vas and outcomes were assessed. Of 40 809 patients (median age 74 years; 32% female), 29% were in the ‘best’, 41% in the ‘good’, 25% in the ‘bad’ and 5% in the ‘worst’ EQ 5D‐vas categories, similarly distributed across all EF categories. Higher New York Heart Association (NYHA) class was strongly associated with lower EQ 5D‐vas regardless of EF categories, followed by chronic obstructive pulmonary disease, smoking, body mass index, higher heart rate, anaemia, previous stroke, ischaemic heart disease, use of diuretics and living alone, whereas higher income, male sex, outpatient status and higher systolic blood pressure were inversely associated with lower EQ 5D‐vas categories. Patients in the ‘worst’ EQ 5D‐vas category as compared with the ‘best’ had the highest risk of all‐cause death [adjusted hazard ratios 1.97, 95% confidence interval (CI) 1.64–2.37 in HFrEF, 1.77, 95% CI 1.30–2.40 in HFmrEF and 1.43 95% CI 1.02–2.00 in HFpEF].ConclusionsMost patients were in the two highest EQ 5D‐vas categories. Higher NYHA class had the strongest association with lower EQ 5D‐vas categories, across all EF categories. Patients in the worst EQ 5D‐vas category were at the highest risk of mortality.

ABSTRACTTo address the challenge of dynamically assessing overhead transmission lines under varying meteorological conditions through manual inspections and drone monitoring, this study proposes an evaluation method for the operating status of overhead transmission lines based on the Analytic Hierarchy Process (AHP). A mathematical model based on AHP is first established to perform weighted processing of five meteorological factors, generating a comprehensive meteorological dataset. A simulation model for the LGJ‐300/70 type conductor is then developed under the temperature field, where temperature distribution during operation is determined based on different meteorological data. Stress variations are observed, and evaluation criteria are established by calculating displacement deviations in the two‐dimensional transmission line model. The transmission line is considered to be in a normal operating state when the maximum displacement deviation is ≤ ±0.63 mm. This demonstrates that the AHP‐based evaluation method can effectively enable dynamic assessment of the operating status of overhead transmission lines.
An Implicit Scheme for Least‐Square Gradient in Coupled Algorithm
Authors: Li Zhao‐Ren , Ou Guo‐Hui , Chen Li , Ji Wen‐Tao , Tao Wen‐Quan 
Published: January 2025

ABSTRACTIn this paper, an implicit scheme that uses the least‐square method to compute the pressure gradient term in the momentum equation, mainly for coupled algorithm was proposed. Accurate computation of the pressure gradient is crucial in computational fluid dynamics, directly influencing the precision of calculation results. The least‐square gradient can reach unconditional second‐order accuracy in the finite volume method. Currently, the least‐square gradient method is predominantly employed in segregated algorithms, primarily utilizing explicit schemes that are not applicable to coupled algorithms. The scarcity of high‐accuracy schemes for computing pressure gradients in coupled algorithms underscores a significant research gap. It contributes by presenting a derivation of an implicit scheme for the least‐square gradient, complemented by an extensive discussion on boundary treatment methods. The efficacy of proposed least‐square method through comparative analysis involving the Green‐Gauss method, as well as benchmarking against existing literature or analytical solutions across distinct cases. The findings demonstrate that, in the majority of cases, the least‐square method offers superior accuracy and convergence rates compared with the Green‐Gauss method.

ABSTRACTInfantile myofibromatosis (IM) comprises a wide clinical spectrum, ranging from solitary or multicentric lesions to generalized life‐threatening forms. IM is mostly linked to germline or somatic heterozygous mutations in the PDGFRβ tyrosine kinase, encoded by the PDGFRB gene. Treatments for IM range from wait and see approach to systemic chemotherapy, according to the clinical context. Targeted therapies, such as tyrosine kinase inhibitors (TKIs) like Imatinib, show promise in treating IM lesions with PDGFRB gain‐of‐function mutations. Here, we report the first evidence of two sporadic, multifocal IM with PDGFRB gene fusions. RNA sequencing analysis revealed two novel fusion transcripts involving the protein kinase domain of PDGFRB, with UBE2I and FN1 genes, respectively. Although gene fusions are frequent and potent oncogenic drivers in soft‐tissue neoplasia, fusion genes involving PDGFRB have not previously been linked to IM. DNA‐based NGS panel testing may not detect chromosomal rearrangements, such as translocations, emphasizing the critical role of comprehensive molecular profiling, including RNA sequencing, in diagnosing and managing children with IM.

Published: January 2025

ABSTRACTThis study examines the transient magnetohydrodynamic (MHD) flow of Walter's‐B viscoelastic fluid over a vertical porous plate within a porous medium, considering the effects of radiation and chemical processes. The nonlinear flow control equations are solved using a closed‐loop method, producing detailed numerical solutions for velocity, temperature, and concentration profiles. Velocity decreases with increasing permeability (K), Schmidt number (Sc), radiation (R), and magnetic field strength (M). In contrast, it increases with higher Prandtl number (Pr), permeability (K), and time (t). Temperature decreases with higher radiation but rises with Prandtl number and time. Concentration decreases with higher permeability and Schmidt number but increases with time. Notably, an increase in the Brownian motion parameter enhances heat and momentum transfer, thickening the velocity and thermal boundary layers. This research has practical applications in fields, such as blood oxygenators, chemical reactors, and polymer processing industries. The novelty of the study lies in its integration of radiation, chemical processes, and MHD flows in the analysis of viscoelastic fluids, a topic that has not been widely explored in previous studies. Future research could focus on optimizing MHD Walter's‐B viscoelastic flow systems, with particular attention to the effects of magnetic field strength and viscoelastic parameters on flow behavior.

Energy Transfer from CRT To Photosensitive Media
Authors: Beiser Leo 
Published: January 2025

SummaryA method is presented for determining the degree of “fit” to be expected between the cathode‐ray tube, as the source of radiation, and a photosensor for subsequent display or data processing. Four most prominent photo‐recording phosphors have been matched with the two basic emulsions to derive a set of transfer indices from CRT to film. Similarly, two of the phosphor types have been matched with two prominent photocathode types to yield similar transfer indices from CRT to photomultiplier. Specification incompatibility and uncertainty have been eliminated by stepping back to the power input to the cathode‐ray tube as the source of energy, and tracing the power losses through the phosphor and the optics in corresponding units.Precaution regarding phosphor decay rates, spectral incompatibility, and intervening elements has brought to light the danger of neglect of such factors. Power transfer equations are developed having indices which may be directly extracted from several tables. The ease with which reliable design conclusions may be reached is demonstrated.
Spread Regression, Skewness Regression, and Kurtosis Regression With an Application to the US Wage Structure
Authors: Chen Qiang , Xiao Zhijie 
Published: January 2025

ABSTRACTQuantile regression provides a powerful tool for investigating the effects of covariates on key quantiles of a conditional distribution. However, we often lack a general picture of how covariates affect the overall shape of the conditional distribution. Using quantile regression estimation and quantile‐based measures of spread, skewness, and kurtosis, we propose spread regression, skewness regression, and kurtosis regression as empirical tools to quantify the effects of covariates on the spread, skewness, and kurtosis of the conditional distribution. This methodology is applied to US wage data during 1980–2019 with substantive findings, and a comparison is made with a moment‐based robust approach. In addition, we decompose changes in the spread into composition effects and structural effects to clarify rising inequality. We also provide the Stata commands spreadreg, skewreg, and kurtosisreg, which are available from the Statistical Software Components (SSC) archive, for easy implementation of spread, skewness, and kurtotis regressions.

Authors: P Valarmathi , A Packialatha 
Published: January 2025

ABSTRACTNowadays, virtual reality (VR) has emerged as a successful new therapeutic strategy in a variety of sectors of the health profession, including rehabilitation, the promotion of inpatients' emotional wellness, diagnostics, surgeon training and mental health therapy. This study develops a new model VRAPMG for children with ASD with the following steps that consider 3D gaming. In this work, the face image is considered to evaluate the attention of the children. In the data acquisition, the input face image is converted into a noncoloured image called a greyscale image. The preprocessing phase is carried out with a median filter and Viola–Jones (VJ) algorithm–based face detection is carried out. Then, the improved active shape model (ASM), shape local binary texture (SLBT) and eye position localization–based features are extracted. In the detection phase, DMO and Bi‐GRU models are combined to form the hybrid classification model. Then, improved SLF is done, and the output is detected. Depending on the detected emotions, it is determined whether the children are attentive or not via entropy‐based attention prediction.

AbstractIntroductionAdults with relapsed or refractory Philadelphia chromosome‐positive B‐cell precursor acute lymphoblastic leukaemia (R/R Ph+ BCP‐ALL) have a dismal outcome. Blinatumomab as a single agent has shown activity in R/R Ph‐ BCP‐ALL, and second or third‐generation tyrosine kinase inhibitors (TKIs) can produce high remission rates in Ph+ leukaemias. We aimed to assess the activity of blinatumomab and TKI in combination with intensive chemotherapy in the relapsed or refractory setting.MethodsTen patients with R/R Ph+ BCP‐ALL were treated with the combination of a modified hyper‐CVAD (mHCVAD) regimen (cyclophosphamide, vincristine, adriamycin, dexamethasone), blinatumomab and TKI (mainly ponatinib).ResultsComplete remission (CR) was achieved in 10/10 patients, with deep molecular responses, and 6/10 were alive in remission after a median follow‐up of 19.4 months. Three major cardiovascular events were noted.ConclusionThese preliminary data, suggest that the mHCVAD‐blinatumomab‐TKI (mainly ponatinib) regimen may achieve a high rate of CR with undetectable measurable residual disease in adults with R/R Ph+ BCP‐ALL and could be proposed to such patients, but cardiovascular or infectious complications should be warning, especially in older or frail patients.

AbstractObjectivesTo evaluate diagnostic testing frequency/yield and determine drivers of hospital charges in a prospective cohort of infants with brief resolved unexplained event (BRUE) to test the hypothesis that length of stay (LOS), low‐yield diagnostic testing, and repeat hospital visits increase costs.MethodsWe conducted a prospective cohort study of infants admitted after BRUE to determine how clinical practice impacts the cost of care. Charge data from our institution's billing records database included room and board, diagnostics, medications, and professional fees for index hospitalizations and 6‐month follow‐ups. Charts were reviewed for clinical data, testing results, and repeat hospitalizations. Parent‐reported symptoms and management changes were obtained by questionnaires. Multivariable analyses with linear regression were conducted to determine risk factors for hospitalization charges and total charges including hospitalization and 6‐month follow‐up.ResultsThe cohort included 155 subjects with median index hospitalization charges of $11,256 and total charges of $15,675. Overall, 76% had persistent BRUE symptoms and 15% repeat hospitalization; 34% were treated with acid suppression. Only 9.7% of the tests performed provided a potential diagnosis, but the videofluoroscopic swallow study (VFSS) had the highest yield with 70% abnormal. On multivariable analysis, LOS, VFSS, flexible laryngoscopy, electroencephalogram, and repeat hospital visits were all associated with increased charges (fold change: 142%–354%).ConclusionsHospitalization and follow‐up care are costly after BRUE. Potentially modifiable drivers of charges include test number, LOS, and repeat hospital visits. Most testing is low‐yield, but timely performance of VFSS may allow for cost‐effective and appropriate treatment of oropharyngeal dysphagia and prevention of persistent symptoms. Gastroenterologists are frequently involved in caring for these children and are uniquely positioned to help guide testing and treatment related to gastroesophageal reflux disease and oropharyngeal dysphagia.
