Published: October 2023

AbstractThe aim of this paper is to study the impact of technologies on the welfare of society through the value co-creation processes that Non-Profit Organizations (NPOs) carry out with social enterprises. Based on the literature on Cross-Sector Social Interactions, the research was aimed at evaluating to what extent certain technological variables (innovation orientation, omnichannel, and ICTs) condition the fact that an NPO, a key agent of social innovation, co-creates (programmes, projects, activities or services) with a social enterprise to improve the social impact and the achievement of the organizational mission of both entities in favour of society. To this end, a research model was developed and its main hypotheses tested with data collected from a sample of Spanish 104 NPOs that collaborate, to a greater or lesser extent, with social enterprises. The study employs partial least squares structural equation modelling in SmartPLS. The article is framed within the most current lines of research on the identification of resources, in this case technological, conditioning the impact of NPOs on the welfare of society. In this sense, this research concludes that the development of a real innovative culture by NPOs and the general use of ICTs are key factors, through the full implementation of an omnichannel strategy, in driving the development of co-creation processes that have a strong transformative impact on the well-being of society.
Colloquialism and genre variation in Chinese
Authors: Li Jialei 
Published: October 2023

Abstract
Colloquialization has been identified as one of the most crucial change processes of the English language, through
which written genres gradually shift towards spoken styles. Colloquialism refers to the synchronous features resulting from
colloquialization. There is limited research into the lexical and phrasal patterns indicating colloquialism in Chinese or how
Chinese colloquialism manifests in different spoken and written genres. To extract the lexical and phrasal patterns indicating
colloquialism in Chinese, this study used a corpus-driven approach to determine and compare keywords and phrase frames from two
training Chinese corpora and those keywords and phrase frames with higher frequencies were retained for further testing.

Abstract
Currently, an increasing quantity of portable energy harvesting modules are being developed to capture the energy generated by human motion. However, the size and weight of a device can affect the smoothness and comfort of a user’s normal limb movements in the process of collecting energy generated by human movement. Especially on manual workers, this effect will significantly increase their physical exertion, so the design of energy-harvesting devices for wearing on manual workers has higher requirements. The bend knee energy harvester (BKEH) designed in the work presented in this paper used a laboratory-made flexible rack to harvest the energy generated by manual workers’ frequently bent knees during work. It converts the collected energy into electricity for various wearable devices to monitor the working status of manual workers and improve their working conditions. One end of the flexible rack is fixed to the upper thigh. When the user bends the knee, the flexible rack will move downward, causing the gear to rotate, thereby collecting the energy generated by the body’s movement. The BKEH was made of many lightweight materials and weighed only 406 g, greatly reducing the impact on the user’s normal limb movements and physical exertion. Practical experiments showed that the BKEH output open-circuit voltage is up to 80.3 V, the output power reached as high as 3.16 W, and the power density reached as high as 7.9 W kg−1, which can effectively supply sufficient electrical power for wearable devices to work normally. The BKEH has a high practical value and good adaptability to human movement posture and can generate enough voltage and power to allow some wearable devices to work properly. These wearable devices can effectively provide users with the ability to monitor their work status and improve working conditions.
Recognizing and correcting for errors in frequency-dependent modulation spectroscopy
Authors: Wilson N M , Aarnio H , Österbacka R 
Published: October 2023

Abstract
This work shows how to acquire reliable data from frequency dependent continuous-wave modulation spectroscopy. We demonstrate this through the example of continuous-wave photoinduced absorption (cwPA), a characterization technique useful for studying long-lived photoexcitations in thin-film solar cell materials. Experimental errors arising at moderate frequencies in modulation spectroscopy are identified and corrected for. Limitations of the detectors and electronics are seen to cause both signal loss and phase shifts. Imperfect charge collection in the detector leads to wavelength-dependent correction factors, while phase shifts caused by the experimental setup call for frequency-dependent corrections. The methods outlined in this work act as a guide to avoid pitfalls in setting up modulation spectroscopy measurements and correcting for limitations.

Hierarchical controlled cyclic quantum teleportation
Authors: Yang Benchao 
Published: October 2023

Abstract
In this paper, a new hierarchical controlled cyclic quantum teleportation scheme is proposed, which can be applied to hierarchical quantum information transmission in a variety of application scenarios. In this scheme, Charlie in the low-level position can only complete simple sending tasks under the control of Bob, while Alice in the middle-level position needs to complete ordinary sending tasks under the control of Charlie and Diana; Bob in the high-level position needs to complete important tasks sent to Charlie under the control of the controller Diana and the high-level controller Eve. Diana and Eve can be regarded as both internal middle and high-level managers as well as different external regulators. Finally, this paper also discusses the number of controllers and their control capabilities, and briefly proposes a simplified hierarchical cyclic quantum teleportation scheme, which provides more options for users with different needs.
Bethe-Heitler lepton pair production in the deuteron breakup reaction*

Published: October 2023

Abstract
We study the lepton pair production via the Bethe-Heitler mechanism in the deuteron breakup reaction. The complete seven-fold differential cross section is calculated with final state interactions taken into account. The deuteron bound state is described by a relativistic covariant deuteron-nucleon vertex. The numerical results indicate that the differential cross section is highly dependent on the lepton's azimuthal angle in regions of small polar angles and exhibits sharp peaks in the distribution over the invariant mass of the generated lepton pair or the two nucleons in the final state. We demonstrate that such a nearly singular feature originates from the collinearity between the produced lepton or antilepton and the incident photon, and it is physically regularized by the lepton mass in our calculation. The final state interaction between the knocked-out nucleon and recoil nucleon redistributes the differential cross section over the missing momentum, with a significant enhancement at a large missing momentum and a suppression in the intermediate region. With a further decomposition of the final state interaction contribution, It is found that the on-shell term dominates the near quasi-elastic region, while the off-shell term dominates the other end. Additionally, we examine the contribution from the interference between the proton amplitude and neutron amplitude, which, as expected, is found negligible even if the proton-neutron rescattering is included. The results of this study can serve as inputs for the analysis and background estimation of multiple exclusive measurements at Jefferson Lab and future electron-ion colliders.
Antibacterial mechanism of Xiuyan jade mineral waste as a natural inorganic antibacterial agent
Authors: Wang Jimei , Wang Xiaoyan , Yang Yang 
Published: October 2023

Abstract
The Xiuyan jade waste exhibits prominent antibacterial properties after mechanical activation; these properties can be further optimized through low-temperature annealing. To elucidate its antibacterial mechanism, analysis methods involving metal-ion leaching monitoring and zeta potential analysis were used. Although the activated waste cannot be easily dissolved in water, Mg2+ and Ca2+ ions precipitated when the waste particles were dispersed in water. The particle surface showed different degrees of electronegativity, which could be the main reason for the antibacterial properties of the material. This study proved the importance of the surface electrical properties of activated waste particles on their properties by observing their adsorption capacity for methylene blue. At the annealing temperature of 270 °C, the Xiuyan jade waste exhibited the highest electronegativity and optimal antibacterial properties as well as the adsorption rate of methylene blue, verifying the significance of electronegativity of activated mineral waste powders on the antibacterial mechanism.

Published: October 2023

Abstract
Non-calcined petroleum coke can serve as an anode material for lithium-ion batteries (LIBs). Nevertheless, this method results in materials with insufficient conductivities and low Coulombic efficiencies during the initial cycle. To address these challenges, the usage of pre-baked carbon anodes as a material for anodes in LIBs is proposed in this study. The surface features of the pre-baked anode (i.e. wrinkle-like filaments) aid in reducing the volume expansion of the electrode during the lithium-ion insertion–removal process. Furthermore, the treatment increases the particle contact area, improving the conductivity of the pre-baked anode. At a current density of 3 A g−1, the pre-baked anode demonstrated an initial discharge capacity and a stable discharge capacity of 548.7 and 134.5 mAh g−1, respectively, after 100 cycles. The capacity of the anode (after 1000 cycles) consistently varies within a narrow range at a current density of 3 A g−1, indicating the stability of the electrode capacity over extended use. Therefore, this study provides valuable insights into exploring potential applications of pre-baked anode materials.

Published: October 2023

Abstract
Since carbon dots (CDs)-metal nanoparticles (MNPs) nanocomposites combine the advantages of both carbon quantum dots (CQDs) and MNPs, they show unique properties and are applied in heterogeneous catalysis. In the nanocomposite catalysts, CDs can act as modifiers to modulate the electronic properties of the metals or produce synergy with the metals. Consequently, the nanocomposite catalysts have good catalytic performance. This paper summarizes the preparation methods of nanocomposite catalysts and focuses on their applications in heterogeneous catalysis. Various specific preparation methods are not only summarized as completely as possible but also are also classified at the macro logic level. The applications of the nanocomposite catalysts in heterogeneous catalysis include photocatalysis, sonocatalysis, electrocatalysis, and thermal catalysis. It also reveals how the nanocomposite catalysts produce excellent catalytic performances in various catalytic reactions. Finally, the existing problems and the direction of future efforts are proposed. It is hoped that this paper will provide a slight reference for the future research of MNPs-CQDs nanocomposite catalysts and their application in the field of catalysis.

Published: October 2023

Abstract
Electrochemical production of hydrogen from water requires the development of electrocatalysts that are active, stable, and low-cost for water splitting. To address these challenges, researchers are increasingly exploring binder-free electrocatalytic integrated electrodes (IEs) as an alternative to conventional powder-based electrode preparation methods, for the former is highly desirable to improve the catalytic activity and long-term stability for large-scale applications of electrocatalysts. Herein, we demonstrate a laser-induced hydrothermal reaction (LIHR) technique to grow NiMoO4 nanosheets on nickel foam, which is then calcined under H2/Ar mixed gases to prepare the IE IE-NiMo-LR. This electrode exhibits superior hydrogen evolution reaction performance, requiring overpotentials of 59, 116 and 143 mV to achieve current densities of 100, 500 and 1000 mA·cm−2. During the 350 h chronopotentiometry test at current densities of 100 and 500 mA·cm−2, the overpotential remains essentially unchanged. In addition, NiFe-layered double hydroxide grown on Ni foam is also fabricated with the same LIHR method and coupled with IE-NiMo-IR to achieve water splitting. This combination exhibits excellent durability under industrial current density. The energy consumption and production efficiency of the LIHR method are systematically compared with the conventional hydrothermal method. The LIHR method significantly improves the production rate by over 19 times, while consuming only 27.78% of the total energy required by conventional hydrothermal methods to achieve the same production.
Vortex detection in atomic Bose–Einstein condensates using neural networks trained on synthetic images

Published: October 2023

Abstract
Quantum vortices in atomic Bose–Einstein condensates (BECs) are topological defects characterized by quantized circulation of particles around them. In experimental studies, vortices are commonly detected by time-of-flight imaging, where their density-depleted cores are enlarged. In this work, we describe a machine learning-based method for detecting vortices in experimental BEC images, particularly focusing on turbulent condensates containing irregularly distributed vortices. Our approach employs a convolutional neural network (CNN) trained solely on synthetic simulated images, eliminating the need for manual labeling of the vortex positions as ground truth. We find that the CNN achieves accurate vortex detection in real experimental images, thereby facilitating analysis of large experimental datasets without being constrained by specific experimental conditions. This novel approach represents a significant advancement in studying quantum vortex dynamics and streamlines the analysis process in the investigation of turbulent BECs.

Abstract

Background
The rapid turnover of the intestinal epithelium is driven by the proliferation and differentiation of intestinal stem cells (ISCs). The dynamics of the F-actin cytoskeleton are critical for maintaining intercellular force and the signal transduction network. However, it remains unclear how direct interference with actin polymerization impacts ISC homeostasis. This study aims to reveal the regulatory effects of the F-actin cytoskeleton on the homeostasis of intestinal epithelium, as well as the potential risks of benproperine (BPP) as an anti-tumor drug.

Methods
Phalloidin fluorescence staining was utilized to test F-actin polymerization. Flow cytometry and IHC staining were employed to discriminate different types of intestinal epithelial cells. Cell proliferation was assessed through bromo-deoxyuridine (BrdU) and 5-ethynyl-2′-deoxyuridine (EdU) incorporation assays. The proliferation and differentiation of intestinal stem cells were replicated in vitro through organoid culture. Epithelial migration was evaluated through BrdU pulse labeling and chasing in mice.

Results
The F-actin content was observed to significantly increase as crypt cells migrated into the villus region. Additionally, actin polymerization in secretory cells, especially in Paneth cells (PCs), was much higher than that in neighboring ISCs. Treatment with the newly identified actin-related protein 2/3 complex subunit 2 (ARPC2) inhibitor BPP led to a dose-dependent increase or inhibition of intestinal organoid growth in vitro and crypt cell proliferation in vivo. Compared with the vehicle group, BPP treatment decreased the expression of Lgr5 ISC feature genes in vivo and in organoid culture. Meanwhile, PC differentiation derived from ISCs and progenitors was decreased by inhibition of F-actin polymerization. Mechanistically, BPP-induced actin polymerization inhibition may activate the Yes1-associated transcriptional regulator pathway, which affects ISC proliferation and differentiation. Accordingly, BPP treatment affected intestinal epithelial cell migration in a dose-dependent manner.

Conclusion
Our findings indicate that the regulation of cytoskeleton reorganization can affect ISC homeostasis. In addition, inhibiting ARPC2 with the Food and Drug Administration-approved drug BPP represents a novel approach to influencing the turnover of intestinal epithelial cells.

Abstract

Background
Multidrug-resistant (MDR) gram-negative bacteria-related infectious diseases have caused an increase in the public health burden and mortality. Moreover, the formation of biofilms makes these bacteria difficult to control. Therefore, developing novel interventions to combat MDR gram-negative bacteria and their biofilms-related infections are urgently needed. The purpose of this study was to develop a multifunctional nanoassembly (IRNB) based on IR-780 and N, N′-di-sec-butyl-N, N′- dinitroso-1,4-phenylenediamine (BNN6) for synergistic effect on the infected wounds and subcutaneous abscesses caused by gram-negative bacteria.

Methods
The characterization and bacteria-targeting ability of IRNB were investigated. The bactericidal efficacy of IRNB against gram-negative bacteria and their biofilms was demonstrated by crystal violet staining assay, plate counting method and live/dead staining in vitro. The antibacterial efficiency of IRNB was examined on a subcutaneous abscess and cutaneous infected wound model in vivo. A cell counting kit-8 assay, Calcein/PI cytotoxicity assay, hemolysis assay and intravenous injection assay were performed to detect the biocompatibility of IRNB in vitro and in vivo.

Results
Herein, we successfully developed a multifunctional nanoassembly IRNB based on IR-780 and BNN6 for synergistic photothermal therapy (PTT), photodynamic therapy (PDT) and nitric oxide (NO) effect triggered by an 808 nm laser. This nanoassembly could accumulate specifically at the infected sites of MDR gram-negative bacteria and their biofilms via the covalent coupling effect. Upon irradiation with an 808 nm laser, IRNB was activated and produced both reactive oxygen species (ROS) and hyperthermia. The local hyperthermia could induce NO generation, which further reacted with ROS to generate ONOO−, leading to the enhancement of bactericidal efficacy. Furthermore, NO and ONOO− could disrupt the cell membrane, which converts bacteria to an extremely susceptible state and further enhances the photothermal effect. In this study, IRNB showed a superior photothermal-photodynamic-chemo (NO) synergistic therapeutic effect on the infected wounds and subcutaneous abscesses caused by gram-negative bacteria. This resulted in effective control of associated infections, relief of inflammation, promotion of re-epithelization and collagen deposition, and regulation of angiogenesis during wound healing. Moreover, IRNB exhibited excellent biocompatibility, both in vitro and in vivo.

Conclusions
The present research suggests that IRNB can be considered a promising alternative for treating infections caused by MDR gram-negative bacteria and their biofilms.
