AbstractBackgroundA novel contact force (CF) sensing catheter with a mesh‐shaped irrigation tip (TactiFlexTM SE, Abbott), is expected to provide safe and effective radiofrequency ablation. Our previous study revealed that the TactiFlex catheter needs a higher power for pulmonary vein isolation (PVI) due to the long tip length. This study aimed to examine the feasibility and safety of a 50 W ablation with the TactiFlex for PVI of atrial fibrillation (AF).MethodsA PVI was performed in 100 AF patients using TactiFlex catheters with a 50 W setting, 5‐20 g CF, and 15–20 s ablation time. The primary outcomes included a successful PVI, the incidence of first‐pass isolations (FPIs), the presence of PV conduction gaps, and the incidence of complications.ResultsFPIs were achieved for 82/100 (82%) right pulmonary veins (RPVs) and 87/100 (87%) left PVs (LPVs). Among the unsuccessful RPV FPIs, residual carina potentials were observed in 16/18 cases (89%), PV gaps in 1/18 cases (5.5%), and both carina and PV gaps in 1/18 cases (5.5%). Similarly, among the unsuccessful LPV FPIs, residual carina potentials were observed in 11/13 cases (84.6%), PV gaps in 1/13 cases (7.7%), and both carina and PV gaps in 1/13 cases (7.7%). Periesophageal nerve injury occurred in 1/100 cases (1%), and no cardiac tamponade occurred. The overall AF‐free rate at one‐year was 81.7%.ConclusionsThe 50 W ablation with the TactiFlex demonstrated a high rate of an FPI, low incidence of PV gaps, and proved to be a safe and effective approach for the initial PVI of AF.

AbstractPersistent cognitive challenges in bipolar disorder (BD) may be tied to insulin resistance, which crucially affects both metabolism and brain health. Additionally, mitochondrial DNA (mtDNA) copy number has emerged as an indicator of cognitive performance and response to treatment in BD. However, it remains unclear whether and how this indicator might serve as a bridge between metabolic dysfunction and cognitive capacity. In 68 study participants with euthymic BD, insulin resistance was assessed according to fasting glucose and insulin levels. mtDNA copy number was quantified from leukocytes, and executive function was measured with the Wisconsin card‐sorting test (WCST). Mediation models were applied to explore the statistical relationship between insulin resistance, mtDNA copy number, and executive function. Both linear regression and Poisson distribution approaches with robust bootstrap simulations were used for significance testing. The results indicated that insulin resistance indirectly affects executive function via mtDNA copy number. This mediation relationship was statistically significant for both preservation errors and completion of categories in the WCST, although there were no significant direct effects of insulin resistance on the executive functions. We therefore concluded that insulin resistance is associated with reduced mtDNA copy number in blood, which may negatively impact executive functions in patients with euthymic BD. Further work is warranted to determine if improving metabolic and mitochondrial health may lead to better cognitive outcomes in BD.

AbstractIntroductionPsychiatric measurement‐based care (MBC) can be more effective than usual care, but health systems face implementation challenges. Achieving attitudinal alignment before implementing MBC is critical, yet few studies incorporate perspectives from multiple stakeholders this early in planning. This analysis identifies alignment and themes in pre‐implementation feedback from patients, providers, and administrators regarding a planned MBC implementation in a safety net psychiatry clinic.MethodsWe used interview guides informed by Conceptual Model of Implementation Research to gather qualitative pre‐implementation attitudes about perceived Appropriateness, Acceptability, and Feasibility of an MBC measure (Computerized Adaptive Test—Mental Health; CAT‐MH) from five patients, two providers, and six administrators. We applied rapid qualitative analysis methods to generate actionable feedback for department leadership still planning implementation. [Correction added on 22 January 2025, after first online publication: In the previous sentence, the word ‘general’ was replaced with the word ‘generate’.] We used a multistep process to generate thematic findings with potential relevance for other similar mental health settings.ResultsThere was more attitudinal alignment across stakeholder groups regarding MBC's Acceptability and Feasibility than its Appropriateness. All three groups agreed that it was important to contextualize MBC for patients and providers, anticipate MBC's impact on patient–provider relationships, and consider the system's capacity to respond to patient needs unearthed by CAT‐MH before implementation began. Our thematic analysis suggests: (1) Introducing MBC may complicate patient–provider relationships by adding a new and potentially conflicting input for decision making, that is, MBC data, to the more typical inputs of patient report and provider expertise; [Correction added on 22 January 2025, after first online publication: In the previous sentence, the word ‘complicated’ was replaced with the word ‘complicate’.] (2) MBC poses theoretical risks to health equity for safety net patients because of limitations in access to MBC tools themselves and the resources needed to respond to MBC data; and (3) Tension exists between individual‐ and system‐level applications of MBC.ConclusionsOur analysis highlights shifting treatment dynamics, equity considerations, and tension between individual‐ and population‐level needs that our participants anticipated when planning for MBC implementation in a safety net psychiatry clinic.

AbstractThe effects of crystal nuclei or crystallization on the isothermal crystallization behavior of isotactic polypropylene homopolymer are examined using fast scanning calorimetry (FSC) and wide‐angle X‐ray scattering (WAXD). During crystalline nucleation below the glass transition temperature as described by Tammann's two‐stage nucleation approach, an increased crystallization rate is observed, regardless of whether the mesophase structures formed in the low‐temperature region or α‐crystals formed in the high‐temperature region. No increase in isothermal crystallization rate is detected following self‐nucleation just above the melting point. Additionally, the influence of the pre‐existing crystals on the subsequent crystallization behavior is investigated by combining crystallization time and temperature profiles, whereby crystallization at high temperatures is followed by slight crystallization at low temperatures, and in reverse order. Surprisingly, it is confirmed that the presence of pre‐existing crystals do not affect the subsequent crystallization rate. The crystallization rate of iPP is influenced only by low‐temperature pre‐annealing that enhances the pre‐nucleation.
Solvent Effects in the Synthesis of Highly Charged Foams of Poly(4‐styrenesulfonate‐co‐glycidylmethacrylate) for Efficient Adsorption of Methylene Blue Enhanced by Aromatic–Aromatic Interactions

Published: November 2024

AbstractWater‐resistant porous solid foams expressing a high amount of benzene sulfonate moieties have been fabricated to enhance the adsorption of cationic aromatic pollutants from wastewaters by aromatic–aromatic interactions. Copolymers of sodium 4‐styrene sulfonate (NaSS) and glycidyl methacrylate (GMA) have been obtained and submitted to thermal treatment at 270 °C for 15 min. The influence of the solvent used in the copolymerization step on foamability and foam stability, when formed, has been studied. The use of water as cosolvent with N,N‐dimethyl formamide (DMF) inhibited foam formation. The use of DMF or DMF/dimethyl sulfoxide (DMSO) = 1:1 as solvents allowed the expansion of copolymers, but the resulting foams are unstable in water, forming hydrogels. However, using DMF/DMSO = 5:1 as solvent, stable water‐resistant foams showing NaSS molar fractions of 43, 57, and 68% are obtained, showing high maximum capacity of 244, 435 and 588 mg g−1 and outstanding pseudo‐second‐order kinetic constants of 1.78, 4.49 and 5.64 g mg−1 min−1 toward adsorption of methylene blue (MB), between 2 and 5 orders‐of‐magnitude higher than referenced adsorbents. This is due to the highly exposed benzene sulfonate active sites / adsorbent mass ratio that induces strong aromatic–aromatic interactions with the cationic aromatic dye.

AbstractThe development of nontraditional luminogens (NTLs) with enhanced and red‐shifted emissions has attracted rapidly increasing attention. Here, a new strategy is provided for preparing NTLs with enhanced and red‐shifted emissions based on polyelectrolyte complexes (PECs) formed by an anionic polyelectrolyte sodium alginate (SA) and a cationic polyelectrolyte polyethyleneimine (PEI). The direct blending of SA and PEI leads to enhanced emissions but no red‐shift in emission wavelengths in the solution and dried films. After soaking in HCl solutions (pH≤2.0), SA‐PEI PEC films are obtained. The SA‐PEI PEC wet and dried films show maximum emissions at ≈ 370 and 470 nm as well as a significantly red‐shifted emission at 550 nm. The SA‐PEI PEC dried films maintain high quantum yields under a wide range of excitation wavelengths and the quantum yield is as high as 29.4% under 470 nm excitation. Furthermore, the films emit nearly white fluorescence under the irradiation of 290 or 370 nm UV light. The enhanced and red‐shifted emission is attributed to the formation of the compact luminescent clusters with more extended through‐space conjugation and rigidified conformations through ionic bonding between NH+ groups and COO− groups and the enhanced hydrogen bonding.

AbstractProperties of pH‐responsive electrospun nanofibers incorporated with biocompatible/degradable Carbopol, commonly used in pharmaceuticals and personal care products, are reported. Sonication of Carbopol dispersions prior to electrospinning leads to uniform incorporation into fibers of the host polymer polyvinylpyrrolidone. The hydration behavior is strongly influenced by pH conditions, forming a viscous network at higher pH. Since Carbopol is more responsive to higher pH, at pH > 6 increasing Carbopol concentration leads to increased uptake volume of buffer solution, faster uptake rate and complete gel formation. The physical spreadability (resulting from a combination of viscoelastic properties and the structural polymer network) of the hydrated fibers is evaluated for multiple Carbopol concentrations and pH conditions. At low starting pH of 4, increasing the Carbopol amount results in slightly increasing viscosity while maintain solution pH. On the other hand, at high starting pH of 8 increasing Carbopol concentrations result in significant reduction in the pH of the buffer solution, which in turn decreases the viscosity of the gel and increases its spreadability. These findings provide guidelines for rational designs of pH responsive Carbopol fibers for various applications, including drug delivery, wound dressing, contraceptive devices, and prevention of sexually transmitted diseases.

Published: November 2024

AbstractAmphiphilic magnetic‐responsive mixed‐shell nanoparticles (Mag‐MSNPs) with tailorable compositions are synthesized by electrostatic‐mediated cross‐linking of core‐forming blocks of two diblock copolymers, followed by in situ growth of magnetite in the cross‐linked core. The Mag‐MSNPs have a magnetic‐responsive core and hydrophilic/lipophilic mixed shells, firmly anchoring at the oil–water interface of emulsified oil droplets due to their high interfacial activity (13.1 mN m−1 at a rather low emulsifier concentration of 1.2 mg mL−1 in the n‐hexane/water system), outperforming most of Janus particles. Driven by the magnetic field, the emulsified oil droplets with Mag‐MSNPs at the interface are drawn to one side for collection. The oil–water separation efficiency reaches 99.5%, manifesting their excellent ability to remove emulsified oil droplets from oily water. After five separation and regeneration cycles, the separation efficiency remains at 98.8%, showcasing their potential for recyclable oily water purification.

AbstractAfter magnetization, the magnetic loss of FeSiAl/SrFe12O19 (SrM) soft magnetic composite is greatly reduced compared with that before magnetization, which has similar effect with FeSiAl magnetic powder core with applied external transverse magnetic field. The experimental results show that the internal bias field provided by SrM ferrite after magnetization increases the average domain size, reduces the number of domain walls and the displacement of domain walls, thereby effectively reducing the hysteresis loss. When the content of SrM ferrite is 8.1 wt.‐%, the magnetic loss is reduced by about 50 %, and the overall performance is the best.
The reinforcing effect of carbon fibers on the mechanical properties of aluminum‐carbon fibers composite sheet prepared by the accumulative roll bonding method

Published: November 2024

AbstractThe 3 K and 6 K (meaning that 3000 or 6000 carbon filaments are contained in one bundle) carbon fibers were embedded by pure aluminum sheets to have a sandwich composite structure under the accumulative roll bonding method. The tensile and cupping tests were carried out to reveal the strengthening mechanism of carbon fibers embedded in the aluminum+carbon fibers composite sheets. The improvements of ultimate tensile and cupping strengths of aluminum+carbon fibers composite sheets reached to be as high as 48 % and 38 %, compared with that of as‐received sheets. With the detailed observation of the tensile and cupping fractures, the underlying strengthening mechanism comes from the bridging effect of carbon fibers during tensile and cupping tests. The accumulative roll bonding method was approved to be an effective way for aluminum+carbon fibers composite sheets preparation with higher tensile and cupping strength.
Fabrication and property evaluation of waste glass dust filled epoxy‐hemp and epoxy‐flax hybrid composites

Published: November 2024

AbstractGlass dust particles, generated in glass cutting industries as a process waste possess health risk and serious environmental issues. This paper essentially reports on exploring the possibility of using this waste glass dust as particulate filler in two different natural fibers (hemp/flax) reinforced polymer composites. Such composites are prepared by hand lay‐up route, varying weight percentages of waste glass dust from 0 to 20. The physical and mechanical characterizations are evaluated experimentally. X‐ray diffractogram analysis reveals the degree of crystallinity of the composites and the phases present in the raw filler. With the incorporation of waste glass dust, the flexural strength, inter‐laminar shear stress and micro‐hardness of the composites are improved up to about 52 %, 44 % and 20 % respectively. On the contrary, tensile and impact strengths tend to decrease about 32 % and 17 % with filler content. Using scanning electron microscopy, the possible mechanisms such as fiber‐matrix de‐bonding, fiber‐pullout, matrix crack and rupture etc. are identified for failures of the composites under tensile, flexural and impact loadings. With low crystallinity and fairly good mechanical properties, these hybrid composites can have potential use in thermal insulations and low‐load engineering applications.

ABSTRACTIn clinical consultation, Shared Decision Making (SDM) between the patient and clinician can inform the patient about available treatment options, likely harms and benefits in order to reach a joint decision that accommodates the patient's preferences. Multi‐Criteria Decision Analysis (MCDA) can be beneficial for this complex problem by offering systematic approaches to elicit preferences for multiple conflicting criteria and evaluate alternatives accordingly. We propose an online SDM tool based on MCDA to guide decisions in clinical consultation where there are multiple treatment options whose outcomes in different factors vary according to the patient. The tool was designed with a panel of domain experts and it enables rapid elicitation of patient preferences and clinician judgements. It is based on Preference Ranking Organization Method for Enrichment Evaluations II (PROMETHEE II) to produce a comprehensive evaluation of the options. The patient‐specific outcomes used in the SDM tool are derived from predictive machine learning models or published evidence. The tool was firstly qualitatively evaluated using a fictitious shoulder pain scenario with three focus groups of consultant and specialist physiotherapists. It was evaluated further with patients via structured interview format. The general response was positive; stating that the tool was informative about options and their performance in multiple criteria, and also useful in making a joint decision. The tool is ready to be incorporated into clinical care and evaluated by clinicians and patients in parallel with existing processes.

ABSTRACTIn order to explain the development prospects and expected benefits of graphene battery material electric vehicles, we introduce electrical energy consumption and graphene battery material preference under the background of carbon trading and dual credit policy and use the Stackelberg game model to solve the optimal decision‐making of the supply chain nodes under different production conditions and then study the social welfare accordingly. The results show that the dual credit policy and carbon trading policy can effectively regulate the production activities of enterprises. Graphene material has a large impact on the market, but its performance is not impressive. The trend of social welfare suggests that graphene materials have great potential.
Bonding the Gap: Surety Bond Guarantee, Defaults, and Small Businesses
Authors: Patel Pankaj C. 
Published: November 2024

ABSTRACTWhen small and medium‐sized enterprises (SMEs) submit bids or tender proposals for projects, they often encounter difficulties in obtaining a surety bond, which is a financial guarantee from a third party that they will meet their contractual obligations. Drawing on transaction cost economics, this study focuses on a seldom‐studied phenomenon of third‐party bond surety programs available to small businesses. For each one‐unit increase in the bond guarantee percentage the odds of default decrease, higher project amount or subcontracting exacerbates the odds of default, and geographic distance between the business and project site does not affect default. The effect sizes are practically meaningful, and the inferences are robust to alternate specifications.
