Published: August 2024

AbstractAdsorptive nanofiber electrospun membranes (ANEMs) show promise for heavy metal removal, particularly in dilute solutions. Nanofibrous polyacrylonitrile (PAN) membranes incorporating Cloisite 20A (C20) organoclay were fabricated via electrospinning for As(V) removal. The impact of C20 on structural properties and As(V) removal efficiency of the nanofiber membranes was investigated. The results indicated that the PAN‐C20 membranes morphology was uniform, with fiber diameters mostly falling within the 100–300 nm range. Incorporation of C20, especially in an exfoliated structure, led to increased hydrophilicity, mechanical strength, and roughness of the membranes. Batch adsorption results revealed that the adding C20 up to 1.5 wt.% significantly enhanced adsorption capacity due to the higher concentration and proper C20 dispersion. Dynamic filtration showed that the PAN‐C20(1.0) membrane achieved over 90% As(V) removal efficiency for 960 min and demonstrated excellent regeneration ability.Highlights
Cloisite 20A organoclay was incorporated into PAN by electrospinning to prepare adsorptive membrane.
Adsorptive membranes were used for As(V) removal from water.
Type of Cloisite 20A dispersion in PAN in dynamic filtration was more important than in static adsorption
PAN‐C20‐1.0 with exfoliated structure showed higher removal efficiency than PAN‐C20‐1.0 with intercalated structure.
PAN‐C20‐1.0 membrane was usable for multiple adsorption–desorption cycles.

AbstractSegregated conductive polymer composites (CPCs) show high conductivity at low loading of filler. However, the weak interactions between fillers and polymer matrix may destroy the mechanical property of the segregated CPCs. Moreover, even with the introduction of dynamic bonds in thermoset polymers, the preparation of thermosetting CPCs remains a big challenge, as most crosslinked polymers should be ground into granules or crushed into powder with liquid nitrogen before mixing with fillers. Herein, the dynamic crosslinked polythiourethane microspheres (PTUM) are designed and synthesized. Then, a special mixing method (the mixing temperature is higher than melting temperature of soft segments of PTUM) is used to make the carbon nanotubes (CNTs) adhering closely to the surface of the crosslinked PTUM, promoting the formation of compacted conductive network. The CNT‐3%/PTUM shows the electrical conductivity of 21.9 S/m and an elongation at break of 472%. Additionally, the CNT/PTUM composites exhibit good self‐healing property, reprocessability, and close‐loop recycling property. The construction of dynamic crosslinked microspheres and compacted segregated conductive network in this work supplies a new approach to prepare thermoset CPCs with simultaneous high electrical conductivity and mechanical property, which is expected to be applied to wearable strain sensors.

ABSTRACTObjectiveAlthough the relative survival rate of childhood cancer has increased substantially in recent years, the pursuit of successful outcomes is often accompanied by negative impacts on pediatric and adolescent cancer survivors and their parents' physical and psychological well‐being. However, little is known about their experiences during the period of cancer survivorship. This study aimed to gain an understanding of the experience of cancer survivorship among pediatric and adolescent cancer survivors and their parents.MethodsThis study utilized a descriptive qualitative study employing the photovoice design. From September 2022 to March 2023, 17 pediatric and adolescent cancer survivors (9–18 years), who had completed active treatment at least 6 months before recruitment, participated in this study. A total of 217 photographs submitted by survivors and their parents and the interview data, were thematically analyzed to identify themes and subthemes.ResultsThe analysis revealed five prominent themes: indelible marks, struggling with late effects, striving to return to normalcy, the strength of support, and living in the moment and hope for the future.ConclusionThe findings shed light on the experiences of pediatric and adolescent cancer survivors and their parents throughout the cancer journey, elucidating the influence on both negative and positive aspects. Additionally, the study highlighted that photovoice facilitated self‐reflection, the discovery of values, and the recognition of strengths and can be a therapeutic strategy for pediatric and adolescent cancer survivors and their parents in further research.
Mutational analysis reveals the importance of residues of the access tunnel inhibitor site to human P‐glycoprotein (ABCB1)‐mediated transport

Published: August 2024

AbstractHuman P‐glycoprotein (P‐gp) utilizes energy from ATP hydrolysis for the efflux of chemically dissimilar amphipathic small molecules and plays an important role in the development of resistance to chemotherapeutic agents in most cancers. Efforts to overcome drug resistance have focused on inhibiting P‐gp‐mediated drug efflux. Understanding the features distinguishing P‐gp inhibitors from substrates is critical. Cryo‐electron microscopy has revealed distinct binding patterns, emphasizing the role of the L‐site or access tunnel in inhibition. We substituted 5–9 residues of the L‐site with alanine to investigate whether the binding of a second inhibitor molecule to the L‐site is required for inhibiting drug efflux. We reveal, for the first time, that mutations in the L‐site affect the drug efflux activity of P‐gp, despite their distance from the substrate‐binding pocket (SBP). Surprisingly, after the mutations were introduced, inhibitors such as tariquidar and zosuquidar still inhibited drug efflux by mutant P‐gps. Communication between the transmembrane helices (TMHs) and nucleotide‐binding domains (NBDs) was evaluated using the ATPase assay, revealing distinct modulation patterns by inhibitors for the mutants, with zosuquidar exhibiting substrate‐like stimulation of ATPase. Furthermore, L‐site mutations abolished ATP‐dependent thermal stabilization. In silico molecular docking studies corroborated the altered inhibitor binding due to mutations in the L‐site residues, shedding light on their critical role in substrate transport and inhibitor interactions with P‐gp. These findings suggest that inhibitors bind either to the SBP alone, and/or to alternate site(s) when the L‐site is disabled by mutagenesis.

AbstractHerein, we present an efficient, one‐pot reaction for accessing 3‐benzylated indoles via the coupling of benzyl alcohols with indoles under heterogeneous catalysis by manganese ferrite (MnFe2O4) nanoparticles. Notably, this reaction, for the first time, employs MnFe2O4 nanoparticles prepared using a simple grinding method. The high compatibility of MnFe2O4 nanoparticles enables a broad substrate scope and high regioselectivity. Moreover, this approach offers several attractive highlights including the use of a recyclable oxide catalyst and green and cost‐effective alkylating reagents under solvent‐free conditions.

Authors: Kirlangiç Burak , Çakmak Esen 
Published: August 2024

AbstractCopper oxide nanoparticles have attracted a great deal of attention in many fields due to their attractive physico‐chemical properties. In particular, their synthesis using an environmentally friendly method offers advantages in many applications. In the present report, copper oxide nanoparticles are produced from extracts of the plant Paulownia tomentosa by a method of biosynthesis. The synthesized CuO NPs have been characterized morphologically and structurally by fourier transform infrared spectroscopy, scanning electron microscopy, energy‐dispersive X‐ray analysis, and X‐ray diffraction. Furthermore, the antimicrobial, antibiofilm and anticancer activities of the synthesized CuO NPs were evaluated. The CuO NPs were spherical and the particle size was 12.5 nm. For the tested microorganisms, CuO NPs showed a high inhibitory effect in terms of antimicrobial and antibiofilm activity. The cytotoxicity of the synthesized CuO NPs against HT‐22 and MCF‐7 showed a dose‐response activity. 50 % inhibitory concentration values were found to be 18.34 and 14.32 μg/mL of CuO NPs against the HT‐22 and MCF‐7 cancer cells, respectively. The results suggest that these nanoparticles can be used as effective antibacterial, antibiofilm and anticancer agents in the biomedical fields.
Seeing the whole: Configurational cognition and new venture resource mobilization

Published: August 2024

AbstractResearch SummaryResearch is scant on how multiple venture attributes combine as “whole packages” of signals (or cognitive configurations) in resource holders’ eyes, shaping a venture's ability to mobilize resources. Drawing on a qualitative comparative analysis of 1,395 crowdfunding campaigns, we identified different configurations of signals for high and low resource mobilization, theorizing abductively their underlying mechanisms through the analysis of case‐level qualitative data. Our results explain some past mixed findings, such as the contradictory effects of social value and entrepreneurial narratives, showing that these narratives can instead be successfully combined in the presence of signals of venture quality and community embeddedness. We show that there is no single best way to impress resource holders, but multiple recipes to holistically communicate a venture's value.Managerial SummaryAnalyzing Kickstarter crowdfunding campaigns, we examine how entrepreneurs combine four signals to raise money: 1) the venture's underlying quality; 2) social networks; 3) narratives; 4) embeddedness in the crowdfunding community. We identified four successful configurations of these signals (500% above the funding goal) and two failing configurations (4% of the funding goal). Narratives per se are not sufficient to mobilize resources, unless backed by signals of quality and community embeddedness. A simpler narrative is supported by cheaper quality signals (product images). More complex narratives (combining social value, entrepreneurial orientation, positive psychology) are supported by more costly signals (videos). Our results encourage entrepreneurs to look beyond “silver bullet” solutions and think holistically how to communicate their ventures as “whole packages”.
When do firms benefit from overconfident CEOs? The role of board expertise and power for technological breakthrough innovation
Authors: Kraft Priscilla S. , Dickler Teresa A. , Withers Michael C. 
Published: August 2024

AbstractResearch SummaryWhile prior upper echelon research has shown that overconfident CEOs are beneficial for innovation, less is known about how firms can harness the benefits of these CEOs for breakthrough innovations. To extend this stream of research, we identify crucial board characteristics that enable firms to benefit from overconfident CEOs in the context of promoting breakthrough innovations. Using longitudinal data of US high‐tech firms, our results emphasize that overconfident CEOs guided by boards with expertise and power strongly outperform fellow CEOs who are monitored by boards lacking either or both of these characteristics. By theorizing and empirically demonstrating how powerful expert boards are important for firms to profit from their CEO's overconfidence, our study provides important contributions to the CEO overconfidence, corporate board, and breakthrough innovation literatures.Managerial SummaryCan boards harness the benefits of overconfident CEOs to increase breakthrough innovation for their firms? We examine this question using a longitudinal dataset of US high‐tech firms and find that board expertise and power enable firms to benefit from CEO overconfidence in the context of breakthrough innovations. Our results suggest that boards need both power and expertise to effectively channel an overconfident CEO's drive toward breakthrough innovations. Interestingly, powerful boards that lack expertise may be detrimental to harnessing CEO overconfidence for breakthrough innovations. For governance practitioners, ensuring that a board is composed of directors with knowledge and understanding of breakthrough innovations and a balance of power with their CEOs will create a beneficial context for firms led by CEO overconfidence to produce breakthrough innovations.

AbstractRainwater harvesting could address freshwater shortages impacting urban agriculture caused by climate change. Limited studies exist on perceptions and concerns about using harvested rainwater for crop irrigation, and to our knowledge none have focused on urban agriculture. We surveyed urban farms and community gardens in Baltimore, Maryland, to document current irrigation practices and water sources and determine interest in rainwater harvesting. We evaluated differences in farm/garden characteristics and water uses between those harvesting rainwater, interested in rainwater harvesting, and not interested in rainwater harvesting. Most Baltimore farms/gardens surveyed were concerned about water availability (59%, n = 20), but all had access to city‐supplied water and only 14% (n = 5) reported water access preventing site expansion. Only 18% of sites used drip irrigation (n = 11), 89% (n = 33) were not using any water filtration, and most (72%, n = 23) had never attended a produce safety training. Twenty‐seven percent (n = 10) of sites were harvesting rainwater, 54% (n = 20) were interested in harvesting rainwater, and 19% (n = 7) were not interested. Ninety percent (n = 9) of the sites currently harvesting rainwater used covered rain barrels, an important strategy for preventing contamination. There were no significant associations between farm/gardens’ rainwater harvesting interests and farming practices, water access and use, or demographics of site respondents. Those currently harvesting rainwater and those interested had numerous concerns about rainwater harvesting including installation, design, and water quality, and were interested in additional information. Offering rainwater harvesting, food safety and education programs to urban farmers and gardeners could increase the safe use of this important water source.
Neutrinoless double beta decay in the minimal type-I seesaw model: mass-dependent nuclear matrix element, current limits and future sensitivities
Authors: Fang Dong-Liang , Li Yu-Feng , Zhang Yi-Yu , Zhu Jing-yu 
Published: August 2024

Abstract
In this work we discuss the neutrino mass dependent nuclear matrix element (NME) of the neutrinoless double beta decay process and derive the limit on the parameter space of the minimal Type-I seesaw model from the current available experimental data as well as the future sensitivities from the next-generation experiments. Both the explicit many-body calculations and naive extrapolations of the mass dependent NME are employed in the current work. The uncertainties of the theoretical nuclear structure models are taken into account. By combining the latest experimental data from 76Ge-based experiments, GERDA and MAJORANA, the 130Te-based experiment, CUORE and the 136Xe-based experiments, KamLAND-Zen and EXO-200, the bounds on the parameter space of the minimal Type-I seesaw model are obtained and compared with the limits from other experimental probes. Sensitivities for future experiments utilizing 76Ge-based (LEGEND-1000), 82Se-based (SuperNEMO), 130Te based (SNO+II) and 136Xe-based (nEXO), with a ten-year exposure, are also derived.

. Such subleading contributions are captured by the fluctuations of the Hubbard-Stratonovich auxiliary field which need to be handled with care due to a subtle divergence structure which we clarify. The examples we consider include the scalar O(N) model, the Gross-Neveu model, the Nambu-Jona-Lasinio model and the massless Chern-Simons Quantum Electrodynamics. We present explicit results for the free energy density to the subleading order in $$ \frac{1}{N} $$

, which captures the thermal one-point function of the stress-energy tensor to this order. We also include the dependence on a chemical potential. We determine the Wilson coefficient in the thermal effective action that is sensitive to global symmetry for the first time directly in interacting CFTs, which produces a symmetry-resolved asymptotic density of states. We further provide a formula from diagrammatics for the one-point functions of general single-trace higher-spin currents. We observe that in most cases considered, these subleading effects lift the apparent degeneracies between observables in different models at infinite N, while in special cases the discrepancies only start to appear at the next-to-subleading order.
Baryon-number-violating nucleon decays in ALP effective field theories
Authors: Li Tong , Schmidt Michael A. , Yao Chang-Yuan 
Published: August 2024

Abstract
The search for baryon-number-violating (BNV) nucleon decay is an intriguing probe of new physics beyond the SM in future neutrino experiments with enhanced sensitivity. The dark sector states such as an axion or axion-like particle (ALP) can induce nucleon decays with distinct signature and kinematics from the conventional nucleon decays. In this work, we study the ALP effective field theories (EFTs) with baryon number violation and the impact of light ALP on BNV nucleon decays. We revisit the dimension-8 BNV operators in the extended EFTs with an ALP field a respecting shift symmetry. The low-energy EFT operators with |∆(B – L)| = 2 and |∆(B – L)| = 0 are matched to the baryon chiral perturbation theory. We obtain the effective chiral Lagrangian and the BNV interactions between ALP and baryons/mesons. The ALP interactions lead to two-body baryon decays B → ℓ (or ν) a and three-body nucleon decays N → M ℓ (or ν) a. We obtain the constraints on the UV scale from the invisible Λ0 decay search at BESIII, the invisible neutron decay search at KamLAND and proton decay search at Super-K. We also show the projections of some other baryon/nucleon decays and present the distinct distributions of kinematic observable.

Abstract
We revisit and extend Fisher’s argument for a Ginzburg-Landau description of multicritical Yang-Lee models in terms of a single boson Lagrangian with potential φ2(iφ)n. We explicitly study the cases of n = 1, 2 by a Truncated Hamiltonian Approach based on the free massive boson perturbed by PT symmetric deformations, providing clear evidence of the spontaneous breaking of PT symmetry. For n = 1, the symmetric and the broken phases are separated by the critical point corresponding to the minimal model $$ \mathcal{M}\left(2,5\right) $$

Abstract
A significant number of prostate cancer patients are long-term survivors after primary definitive therapy, and the occurrence of late side effects, such as second primary cancers, has gained interest. The aim of this editorial is to discuss the most current evidence on second primary cancers based on six retrospective studies published in 2021–2024 using large data repositories not accounting for all possible confounding factors, such as smoking or pre-existing comorbidities. Overall, prostate cancer patients treated with curative radiotherapy have an increased risk (0.7–1%) of the development of second primary cancers compared to patients treated with surgery up to 25 years after treatment. However, current evidence suggests that the implementation of intensity modulated radiation therapy is not increasing the risk of second primary cancers compared to conformal 3D-planned radiotherapy. Furthermore, increasing evidence indicates that highly conformal radiotherapy techniques may not increase the probability of second primary cancers compared to radical prostatectomy. Consequently, future studies should consider the radiotherapy technique and other confounding factors to provide a more accurate estimation of the occurrence of second primary cancers.
