Joint Investment and Pricing Decisions in a Mobile Game Supply Chain Considering Risk Attitudes
Authors: Qu Jiali , Zhang Jiawei , Hu Benyong , Meng Chao 
Published: October 2024

ABSTRACTThis paper studies the joint decision‐making problem of investment and pricing in a mobile game supply chain with a game developer and a distribution platform with different risk attitudes. The investment here involves the mobile game's quality investment during the development process and promotion investment during the operation process. First, the mean–variance utility theory is used to describe the risk attitudes of the supply chain participants. On this basis, considering the mobile game's individualized operational characteristics with respect to production and sales, the supply chain's and its participants' decision‐making models are established with the expected utility as an objective function. Second, the supply chain collaboration is modeled as a Stackelberg game. This paper obtains the optimal decisions of the participants and reveals the effects of the participants' risk attitudes on the optimal quality investment, promotion investment, and pricing policy. Finally, this paper further reveals the relationship between participants' risk attitudes and their expected profits. It is found that participants' risk attitudes will change the relationship between the expected profits under centralized decision‐making and those under decentralized decision‐making. These characteristics remain valid when a different demand format is employed or the supply chain members play a Nash game.
Passage: Rehearsals in linguistic returns

Published: October 2024

AbstractThis project is a rehearsal in language and its capacity to refuse comprehensibility. In this experimental process, we will be exploring the boundaries of legibility through a tracing of the shards and fragments embodied in the minor detail. With our sight fixed toward Palestine, we will explore how detail holds radical potential, be it in classical texts in the canon of Palestinian literature, or in the oral testimonies that have emerged from Gaza over the past 6 months. The focus on illegibility and language that defies comprehension exists in the shadow of genocide, where language fails to capture the immensity of the moment. Broken and sharp, it turns inward into a sense closer to emotion than to logic. In that sense, this project is also a rehearsal in utilizing language as matter, as material, as tangible touch.

ABSTRACTThe environmental problems caused by thermal reactions have prompted the search for new approaches. Photochemical curing, which uses light energy, offers a sustainable solution for polymerizing complex polymers, reducing energy consumption, and emissions. Current study involves cationic UV‐curing of biobased polyurethanes (PU) with a thermo‐responsive shape memory behavior on very low temperature almost equal to human body temperature. This product has a potential to be utilized as drug carrier or related biomedical applications, as well as self‐tightening materials against human body heat. Polymer has been designed from sesame oil, with slight modification through a facile epoxidation approach. Main objectives of this research were to prepare biobased PU recipe; to utilize a specially designed UV‐curing approach for this synthesis; and to develop shape memory properties upon sensing human body temperature. Prepared material has been analyzed through FTIR, SEM, TGA, DSC, water absorption capacity (WAC), and gel contents (GCs). Shape memory behavior has been tested in both air and water against a range of temperatures (35°C–80°C). At 35°C in 208 s, prepared sample, presented 96.60% Rr and 90.56% Rf, whereas at 80°C in 55 s Rr increased to 98.33% and Rf increased to 100%. Hydrophobic nature of sample was confirmed by 4.1% water absorption in 48 h.

AbstractBackgroundYouth sports coaches play a critical role in proper concussion recognition and management, reinforcing the need for coach concussion education. As of 2021, most states have statutory and policy measures mandating concussion education for coaches. In practice, these mandates have been enacted through state legislatures and their respective youth sport governing bodies. Prior studies have found significant variations in the contents of state‐level concussion risk reduction policies and have raised questions about their specificity.ObjectiveTo expand on previous analyses to provide an overview of youth sports coach concussion education, highlighting variations in state policies and discrepancies between state mandates and youth sport governing bodies.MethodsThis report utilized qualitative content analysis to characterize and compare U.S. state and governing body concussion education requirements for youth sport coaches. State concussion statutes were identified via the National Conference of State Legislatures and Open States databases, and governing body handbooks/bylaws were obtained via their websites. Two researchers independently coded the policies, and discrepancies were resolved through consensus meetings with additional youth traumatic brain injury experts.ResultsWe found significant variability in educational requirements and their implementation. A majority (68%; n = 34) of states require the completion of concussion education training for coaches. Notably, many states designate responsibility for enforcement and implementation of provisions to another party but just four state statutes delineate explicit consequences for noncompliance. Additionally, only 12 state statutes extend mandates to noninterscholastic sports, limiting their reach. In most cases, independent sanctioning authorities implement more stringent policies than the minimum acceptable standard established by state law.ConclusionOur findings provide a coded data set of youth coach concussion laws and independent sanctioning authority guidelines that can be used in future research efforts. Further research investigating a relationship between the strength of coach concussion education policies and relevant youth and adolescent concussion‐related metrics is required.

Published: October 2024

ABSTRACTMost vertical form, fill and seal machines use thermoplastic films. However, the gradual shift towards sustainability has created challenges for the packaging industry to employ flexible coated paper‐based materials for packing products. Forming shoulders are a crucial component in packaging machinery for creating coated paper‐based packaging as the size and shape of the packaging depend on their geometrical features. However, the shoulder geometry and design can negatively affect paper packaging by causing unwanted wrinkles and tears, which can affect the shelf lives of products. Therefore, this study focused on developing a new shoulder and optimizing its geometrical parameters for coated paper‐based packaging. Conventional forming shoulders were experimentally investigated by evaluating the influence of their geometrical parameters on flexible coated papers before focusing on optimizing the new shoulder. Additionally, this study aimed to improve the overall runnability and convertibility of the coated paper on the forming shoulder. The newly designed optimized shoulder features an enhanced geometry that can minimize the stress–strain effect. Additionally, the computerized numerical control machined new shoulder features improved web tracking and material handling process. The study achieved to produce lower surface roughness with minimum number of wrinkles on the pillow bag's surface. Furthermore, it ensures that the oil‐ and grease‐resistance properties of the converted coated paper are maintained and feature an enhanced geometry that minimizes the stress–strain effect on paper, thereby offering a more sustainable and efficient packaging solution.

Published: October 2024

AbstractA straightforward microfluidic approach has been developed to fabricate the monodisperse thermo‐responsive self‐bursting poly(N‐isopropylacrylamide) (PNIPAM) microcapsules for the rapid on‐demand release of liposoluble drugs. The PNIPAM microcapsules possess excellent structural integrity with a dense shell and spacious cavity, providing ample space for encapsulating liposoluble matters. The swollen hydrogel shells effectively prevent drugs leakage and contamination below the volume phase transition temperature (VPTT), while the shrunken hydrogel shells enable drugs to release from microcapsules above the VPTT. The microcapsules demonstrate rapid thermo‐responsiveness, with drug release occurring within 4–6 minutes and subsequent swelling taking place within 2–3 minutes. The PNIPAM microcapsules exhibit a reversible and repetitive swelling/shrinking response to temperature changes. The thermo‐responsive self‐bursting PNIPAM microcapsules exhibit great potential as microcarriers for encapsulating, storing, and rapidly releasing liposoluble substances such as drugs, fluorescent dyes, corrosion inhibitors, and other chemical ingredients. The simple, controllable and reproducible microfluidic approach presented here provides valuable guidance for the design and fabrication of monodisperse PNIPAM microcapsules.

Published: October 2024

AbstractBifunctional catalysts are widely used in the hydroisomerization of long‐chain n‐alkanes, which are of great significance in the production of high value‐added chemicals. Herein, the Ni/ZSM‐23‐W and Ni/ZSM‐23‐EG catalysts were prepared using water and ethylene glycol, respectively. The catalysts were characterized using XRD, SEM, TEM, NH3‐TPD, Py–IR, H2‐TPR, H2‐TPD, ICP–OES, and XPS, and their catalytic performance was evaluated by conducting the hydroisomerization of n‐hexadecane as a model reaction. It was revealed that the polarity of the impregnating solvent has a significant impact on the dispersion of Ni nanoparticles. When employing ethylene glycol as a solvent, a strong interaction occurred between NiOx and ZSM‐23 in the Ni/ZSM‐23‐EG catalyst, which facilitated the formation of small‐sized and well‐dispersed Ni nanoparticles. Consequently, the Ni/ZSM‐23‐EG catalyst demonstrated a strong hydrogenation capacity, yielding an impressive 72.9% of iso‐hexadecanes yield.
Molten‐Salt‐Assisted Synthesis of Carbon‐Doped BN Nanosheets for the Sensitive Detection of Paracetamol
Authors: Shen Hao , Ouyang Huiying , Li Weifeng , Long Yumei 
Published: October 2024

AbstractHigh‐performance sensors are in constant demand for health care and environmental protection. In this study, a sensitive paracetamol (PCM) sensor was designed by modifying glassy carbon electrode (GCE) with carbon‐doped boron nitride (BCN/GCE) nanosheets. The BCN nanosheets were synthesized using a molten‐salt method, which ensured the uniformity of size distribution. X‐ray diffraction and transmission electron microscopy results suggested that the carbon‐doping hardly changed the crystal structure and morphology of hexagonal boron nitride (HBN). However, the carbon‐doping can reduce the bandgap, increase the specific surface area and improve the electrical conductivity, which is attributed to the formation of abundant point defects in the BN crystal. These point defects modulate electronic structure and surface activity, and further improve the electrocatalytic properties of BN. The BCN nanosheets exhibited outstanding electrocatalytic activity in the oxidation of paracetamol (PCM). With the help of square wave voltammetry (SWV) method, the BCN/GCE demonstrated linear current response towards PCM covering the concentrations of 0.05–70 μM and 70–200 μM with a detection limit (LOD) of 0.0086 μM. The developed method also showed excellent selectivity and high stability. In addition, the BCN/GCE sensor worked well when it was applied to quantify PCM in actual samples.

AbstractThe following is an abstract of the study. The objective of this study was to identify the chemical constituents of Jasmine Leaves and predict their potential sedative effects. A rapid chemical analysis identified the compounds present in Jasmine Leaves. A database was created to establish “target‐disease” and “compound‐target” networks. Four machine learning models were developed and evaluated to predict the sedative potential of various compounds. Molecular docking was performed on the two most promising compounds identified through network analysis and their respective targets. A total of 34 compounds were identified in Jasmine Leaves. Eight compounds, including citric acid and Pogostone, were identified as being associated with genes involved in the process of sedation. The Random Forest (RF) model showed the best performance, with an accuracy of 0.75, an F1 score of 0.76, an AUC of 0.83, a sensitivity of 0.70, a specificity of 0.72, a precision of 0.77, and an MCC of 0.42. The model predicted the potential sedative effects of citric acid and Pogostone with probabilities of 0.51 and 0.29, respectively. Molecular docking results indicated that citric acid and Pogostone had strong interactions with tyrosinase and gamma‐aminobutyric acid type A (GABAA) receptors, with MOE software scores of −3.83 and −4.18, respectively. This study concludes that a rapid assessment method was developed to evaluate the pharmacological potential of natural products, suggesting that Jasmine Leaves may exert sedative effects through interactions between citric acid and Pogostone with tyrosinase and GABAA receptors. Additionally, Jasmine Leaves show promise as a cost‐effective sleep aid beverage.

Published: October 2024

AbstractOrganic luminogens play an indispensable role in optoelectronic devices, yet there is a pressing need to address their aggregation‐caused quenching (ACQ) and stability. Here we designed and prepared multilayered boron nitride nanosheets/fluorescein isothiocyanate (MBNNSs/FITC) composite phosphors with tunable photoluminescence by controlling the FITC content and annealing temperature. The research results indicate that MBNNSs/FITC with low or high loading of FITC is not conducive to enhancing the emission intensity of FITC, which can be attributed to the fact that low loading leads to a decrease in the content of fluorescent groups, while high loading promotes intermolecular aggregation of FITC dyes. Interestingly, the emission intensity of FITC in MBNNSs/FITC‐6 composite phosphors can be further enhanced by annealing treatment (200 °C), which can be ascribed to the suppression of the ACQ and effective energy transfer from the MBNNSs to the FITC. Moreover, the resultant composite phosphor displays outstanding thermal stability, remarkable photo stability and exceptional water‐resistance. This work provides a new design space for the development of non‐rare‐earth fluorescent materials using organic fluorescent dyes.

AbstractThe utilization of biologically active metal complexes in medicine is gaining recognition as an alternative approach to traditional biologically active organic molecules, which often exhibit undesirable side effects. This study focuses on the synthesis and characterization of a Co(II) complex derived from the (E)‐2‐((2‐hydroxybenzylidene)amino)‐5‐methylbenzonitrile ligand system (HL) and cobalt(II) acetate tetrahydrate in a dichloromethane/methanol solution. A comprehensive characterization strategy was employed, involving proton and carbon nuclear magnetic resonance, infrared, electronic spectra, PXRD, SEM‐EDX, and mass spectroscopies, as well as elemental analysis (CHN and Co), TGA, and molar conductance, to confirm the chemical structures of the ligand and its complex. The infrared spectral data revealed the ligand as a bidentate ligand, chelating the Co(II) ion through the oxygen and nitrogen atoms of the phenolate and imine groups. Additionally, PXRD and SEM analyses indicated crystalline and amorphous properties for the ligand and complex, respectively. Assessment of antimicrobial potential using a modified disc diffusion method, with streptomycin as the positive control, demonstrated the complex's enhanced antibacterial activity compared to the ligand against all tested bacteria, showing a concentration‐dependent response. Similarly, antioxidant studies revealed promising results, with the complex exhibiting superior DPPH radical scavenging activity (IC50 values: ligand 64.5 μg.mL−1, complex 43.1 μg.mL−1). Theoretical analysis through DFT calculations and molecular docking provided insights into the electronic properties and binding affinity of the ligand and complex, supporting the experimental findings and affirming the biological activities exhibited by the compounds. Overall, this research showcases the synthesis, characterization, and biological evaluation of a promising Co(II) complex, highlighting its potential as an effective antimicrobial and antioxidant agent.

AbstractA series of 2,2′‐(1,4‐phenylene)bis(N‐substituted phenylthiazolidine‐4‐amide) derivatives, denoted as (A3–9), were synthesized, and characterized for their potential applications against prostate cancer cells (PC3), and Candida albicans fungi. These compounds incorporate various substituents on the phenyl ring such as 4‐NO2, 3‐NO2, 4‐COCH3, 4‐H, 4‐OCH3, 4‐OCH2CH3, and 4‐Cl. The chemical structures of these derivatives were confirmed by NMR, FTIR, and mass spectroscopy. Biological assays, utilizing the MTT assay for prostate cancer cells (PC3) and the disk diffusion assay for Candida albicans fungi, were conducted to evaluate the bioactivity of these compounds. The results revealed promising cytotoxic and antifungal activities. Specifically, compounds A3 (IC50=69.74±0.96), A4 (IC50=63.64±0.950), and A9 (IC50=57.14±0.88 μg/mL) exhibited notable potency against PC3 cells, while A7 and A8 exhibited considerable antifungal efficacy against Candida albicans with MIC of 312 μg/mL. Moreover, density functional theory (DFT) simulations were used to study electronic properties and reactivity descriptors such as energy gap (Eg), ionization potential (IP), electron affinity (EA), chemical potential (μ), chemical hardness (η), global softness (σ), electronegativity (χ), and electrophilicity (ω) to gain a better understanding of the Structure‐Activity Relationship (SAR). Molecular docking analysis against DNA Gyrase and EGFR tyrosine kinase enzymes revealed strong binding interactions of the investigated molecules within their active sites, making them valuable candidates for further development as therapeutic agents against prostate cancer and fungal infections. POM analysis indicates the presence of two antifungal pharmacophore sites (O1δ−, O2δ−) and (O3δ−, O4δ−), as well as two antitumor pharmacophore sites (O1δ−, NH1δ+) and (O4δ−, NH2δ+).

AbstractSupercapacitors (SCs) are crucial for high‐performance energy storage, offering high power density, swift charge–discharge rates, and durability. The enhancement of their performance hinges on the development of advanced electrode materials. This study presents an innovative method involving polyacrylonitrile (PAN) nanofibers adorned with manganese dioxide (MnO₂) nanoparticles (NPs), created through electrospinning and subsequent thermal treatment. This synergy exploits the extensive surface area and electrical conductivity of PAN nanofibers along with the substantial capacitance of MnO₂. The MnO₂‐coated PAN nanofibers reached an impressive specific capacitance of 247 F g−1 at a scan rate of 10 mVs−1, markedly boosting the efficacy of all‐solid‐state asymmetric SCs. The SCs, incorporating a polyvinyl alcohol (PVA)/potassium hydroxide (KOH) gel electrolyte, exhibited an energy density of 8.2 Wh kg−1 at a power density of 700 W kg−1, preserving 80.4% of their original capacitance after 5000 cycles. This research is pioneering in combining MnO₂ with PAN nanofibers, marking a significant leap forward in supercapacitor technology with enhanced energy storage capacity and prolonged stability. These findings underscore the promise of these composite materials in future energy storage solutions.

AbstractThree 8‐coordinated terbium acylpyrazolone complexes [Tb(DMBPMP)3(H2O)2] (Tb1), [Tb(DMBMCPMP)3(H2O)2] (Tb2), and [Tb(DMBPTMP)3(H2O)2] (Tb3) with a distorted bicapped trigonal prismatic structure were synthesized (where, 3,5‐dimethylbenzoyl 1‐(phenyl = DMBPMP/m‐chlorophenyl = DMBMCPMP/p‐tolyl = DMBPTMP) 3‐methyl 5‐pyrazolone). The structures of the complexes were comprehensively analyzed using mass ESI, FTIR, UV–vis, powder XRD, and TG‐DTA methods. Single‐crystal analysis of Tb3·H2O confirmed an eight‐coordinate structure (TbO8) with a distorted bicapped trigonal prismatic geometry. In the on‐state emission spectrum, the 5D4 → 7F5 transition exhibits hypersensitivity in the green region of the visible spectrum (∼540–560 nm). The differences between electric dipole (ED) and magnetic dipole (MD) transitions indicate a small degree of asymmetry. The examination of solid‐state emission spectra included the assessment of intensity, G/B ratio, green color purity, and the antenna effect energy diagram.
