Published: November 2023

AbstractDeveloping a facile strategy for constructing oriented mixed matrix membranes (MMMs) with uniformly dispersed and high‐loading metal–organic frameworks (MOFs) is a crucial scientific challenge in probing the enhanced capability and potential applications of MOF‐polymer MMMs. Herein, a novel synchronous synthetic method for constructing oriented CuBDC/poly(m‐phenylenediamine) (CuBDC/PmPD) MMM with uniform MOF dispersion at high loading at the air–solution interface via the dual function of metal ions is reported. The resulting MMM exhibits excellent separation performance in ion sieving and seawater desalination due to the structural integrity of the proposed membrane and the highly interconnected channels created through the oriented distribution of MOF in a polymer matrix. Such a cutting‐edge approach may provide promising insights into the development of advanced MMMs with optimized structure and superior performances.

AbstractThe design and fabrication of NO‐evolving core‐shell nanoparticles (denoted as NC@Fe), comprised of BNN6‐laden COF@Fe3O4 nanoparticles, are reported. This innovation extends to the modification of 3D printed polyetheretherketone scaffolds with NC@Fe, establishing a pioneering approach to multi‐modal bone therapy tailored to address complications such as device‐associated infections and osteomyelitis. This work stands out prominently from previous research, particularly those relying on the use of antibiotics, by introducing a bone implant capable of simultaneous NO gas therapy and photothermal therapy (PPT). Under NIR laser irradiation, the Fe3O4 NP core (photothermal conversion agent) within NC@Fe absorbs photoenergy and initiates electron transfer to the loaded NO donor (BNN6), resulting in controlled NO release. The additional heat generated through photothermal conversion further propels the NC@Fe nanoparticles, amplifying the therapeutic reach. The combined effect of NO release and PPT enhances the efficacy in eradicating bacteria over a more extensive area around the implant, presenting a distinctive solution to conventional challenges. Thorough in vitro and in vivo investigations validate the robust potential of the scaffold in infection control, osteogenesis, and angiogenesis, emphasizing the timeliness of this unique solution in managing complicated bone related infectious diseases.

Published: November 2023

AbstractA sonication‐assisted liquid‐phase preparation technique is developed to prepare boron quantum dots (BQDs) with a lateral size of 3 nm in a solution of NMP and NBA; it shows a direct bandgap semiconductor with a bandgap of 3 eV and a specific capacitance of 41 F g−1. A BQDs(10)‐Ti3C2Tx membrane electrode with excellent capacitance and high flexibility is prepared by using Ti3C2Tx nanosheets (NSs) as assembled units and BQDs as pillar; it gives a specific capacitance of 524 F g−1 at 1 A g−1 in 6 m H2SO4 electrolyte, a high capacity retention of 75%, and a minimum relaxation time of 0.51 s. An all‐solid‐state BQDs(10)‐Ti3C2Tx flexibility supercapacitor is assembled by using a BQDs(10)‐Ti3C2Tx membrane as electrodes and PVA/H2SO4 hydrogel as electrolyte; it not only shows an area specific capacitance of 552 mF cm−2 at 1.25 mA cm−2, a retention rate of 75%, a capacity retention of 93% after 5000 cycles, and an energy density of 40.4 Wh cm−3 at a volume power density of 416 W cm−3, but also provides superior flexibility and can be bent to different degrees, showing that the assembled BQDs(10)‐Ti3C2Tx membrane electrode and BQDs(10)‐Ti3C2Tx flexible supercapacitor display broad application prospects in field of portable/wearable electronic devices.

AbstractComposite biocatalysts (CB) consisting of amylases and Saccharomyces cerevisiae immobilized separately on bacterial nanocellulose (BNC) are used for the process of simultaneous saccharification and fermentation (SSF) of starch (5%, w/v) for bioethanol production. Parameters such as: i) addition of phosphates and/or divalent metal‐ions salts during the co‐immobilization process of the amylases, ii) required co‐immobilization time, iii) fermentation temperature and initial pH of starch, and iv) CB as single or double freeze‐dried are studied. The utilization of double freeze‐dried CB exhibits fermentation efficiency 89.9% and ethanol yield 0.51 g ethanol g−1 starch while the single freeze‐dried CB 81.1% and 0.46 g ethanol g−1 starch, respectively. In the case of double freeze‐dried CB, the fermentation efficiency decreases by only 27.1% in two‐recycling batches, while in the single freeze‐dried one decreases by 51.3%. The application of double freeze‐dried CB can be used for: i) the eco‐friendly biosynthesis of value‐added bioproducts; ii) the promising option for fuel‐grade bioethanol through starchy wastes or foodstuff starchy residues treatment, and iii) the implementation of industrialization. Finally, to simulate an industrial process of one‐step SSF of starch by applying a CB model, a technoeconomic analysis is evaluated, where using BNCs makes the bioprocess cost‐effective and environmentally favorable, simultaneously.
Government‐enterprise collusion and public oversight in the green transformation of resource‐based enterprises: A principal‐agent perspective
Authors: Li Cunfang , Gu Xinyi , Li Zhan , Lai Yongzeng 
Published: November 2023

AbstractIn this work, by constructing a principal‐agent model, we analyze the intrinsic causes of collusion between the government and enterprises, particularly through the central and local governments and resource‐based enterprises. The analysis has been conducted by introducing the public as a third‐party monitoring body to explore the positive role of public participation in preventing collusion between the government and enterprises, and henceforth entailing model analysis and validation with certain examples. The green transformation of resource‐based enterprises is an effective way for their sustainable development, besides being an inevitable requirement for China's high‐quality economic development and ecological civilization construction in the new era. In this perspective, our study reveals that: (1) Government‐enterprise collusion is motivated by the central government's improper assessment and incentive mechanism, besides the information deficit between the central government and the colluding parties. (2) The conditions for government‐enterprise collusion in development remain on the resource‐based enterprises and local governments that face fewer expected penalties than expected benefits, thus resulting in lower collusion risks. (3) Public participation in monitoring can effectively combat the willingness of the local governments and resource‐based enterprises to collude and significantly increase the level of effort of both parties in the green transition. (4) Public monitoring increases the probability of collusion detection, and prompt detection improves the timeliness and effectiveness of punishment. The findings from this study can provide a scientific basis for improving the regulatory system, thus improving public participation and strengthening the penal system.

AbstractBackgroundAlthough poor medication adherence has a negative impact on disease prognosis in patients with inflammatory bowel disease (IBD), finding proven solutions remains a challenge. In this study, we developed a telehealth management model based on education and patient‐centered medical care (PCEB) using the social media platform WeChat.ObjectiveTo investigate the effect of PCEB on adherence and clinical outcomes.MethodsIn this retrospective cohort, 543 IBD patients (274 in the PCEB group and 269 in the routine group) at the IBD center of Renmin Hospital (Wuhan University, Wuhan, China) were enrolled between January 2020 and September 2022. The routine group received routine follow‐up and management, while for PCEB patients, a comprehensive IBD education program and PCEB were conducted. Medication adherence and clinical outcomes were also evaluated.ResultsThere were no differences between the PCEB and routine groups in terms of patient demographics and clinical characteristics, including disease classification, duration, biological treatment, and educational background at baseline. Compared with routine treatment, PCEB greatly improved patient medication adherence, as assessed by compliance with oral medication, enteral nutrition, biological infusion, and scheduled endoscopic assessment. Clinical and endoscopic remission in patients with PCEB increased during short‐term (month 4) and long‐term (month 12) follow‐ups, along with a decrease in relapse rates for CD (13.3% vs. 31.8%) and UC (19.8% vs. 37.2%).ConclusionThe telehealth model applied to the PCEB group improved medication adherence and clinical outcomes in patients with IBD. This is a new and powerful solution for the long‐term management of this chronic and progressive disease.
Scattering amplitudes from dispersive iterations of unitarity
Authors: Tourkine Piotr , Zhiboedov Alexander 
Published: November 2023

Abstract
We present and numerically implement a computational method to construct relativistic scattering amplitudes that obey analyticity, crossing, elastic and inelastic unitarity in three and four spacetime dimensions. The algorithm is based on the Mandelstam representation of the amplitude and iterations of unitarity. The input for the iterative procedure is given by the multi-particle double spectral density, the S-wave inelasticity, and the value of the amplitude at the crossing-symmetric point. The output, obtained at the fixed point of the iteration of unitarity, is a nonperturbative scattering amplitude. The amplitudes we obtain exhibit interesting features, such as non-zero particle production, intricate high-energy and near the two-particle threshold behavior. Scattering amplitudes obtained by initializing the iteration process with zero (or small) multi-particle input end up close to saturating the S-matrix bounds derived by other methods. There is a version of the iterative algorithm that is directly related to Feynman diagrams: it effectively re-sums infinitely many two-particle reducible planar Feynman graphs in the ϕ4 theory, which remarkably produces a unitary nonperturbative scattering amplitude function. Finally, we discuss how the algorithm can be further refined by including multi-particle unitarity.
Particle realization of Bondi-Metzner-Sachs symmetry in 2 + 1 space-time
Authors: Batlle Carles , Campello Víctor , Gomis Joaquim 
Published: November 2023

Abstract
We construct a Lorentz invariant massive particle model in (2+1) space-time with an enlarged set of symmetries which includes Bondi-Metzner-Sachs (BMS) translations (supertranslations), using the non-linear realization framework. The Hamiltonian formalism for the resulting Lagrangian is constructed, and the infinite phase-space constraints and the set of gauge transformations are analysed. We also compute the massless limit of the theory in phase-space. After eliminating the gauge degrees of freedom, the physical reduced space is left only with the degrees of freedom of a standard Poincaré particle but with a residual set of symmetries that we prove to be BMS. A similar result for the massless limit, including in this case superrotations, is pointed out.
Integrable coupled massive Thirring model with field values in a Grassmann algebra

Published: November 2023

Abstract
A coupled massive Thirring model of two interacting Dirac spinors in 1 + 1 dimensions with fields taking values in a Grassmann algebra is introduced, which is closely related to a SU(1) version of the Grassmannian Thirring model also introduced in this work. The Lax pair for the system is constructed, and its equations of motion are obtained from a zero curvature condition. It is shown that the system possesses several infinite hierarchies of conserved quantities, which strongly confirms its integrability. The model admits a canonical formulation and is invariant under space-time translations, Lorentz boosts and global U(1) gauge transformations, as well as discrete symmetries like parity and time reversal. The conserved quantities associated to the continuous symmetries are derived using Noether’s theorem, and their relation to the lower-order integrals of motion is spelled out. New nonlocal integrable models are constructed through consistent nonlocal reductions between the field components of the general model. The Lagrangian, the Hamiltonian, the Lax pair and several infinite hierarchies of conserved quantities for each of these nonlocal models are obtained substituting its reduction in the expressions of the analogous quantities for the general model. It is shown that, although the Lorentz symmetry of the general model breaks down for its nonlocal reductions, these reductions remain invariant under parity, time reversal, global U(1) gauge transformations and space-time translations.
Critical Edges in Rips Complexes and Persistence
Authors: Goričan Peter , Virk Žiga 
Published: November 2023

AbstractWe consider persistent homology obtained by applying homology to the open Rips filtration of a compact metric space (X, d). We show that each decrease in zero-dimensional persistence and each increase in one-dimensional persistence is induced by local minima of the distance function d. When d attains local minimum at only finitely many pairs of points, we prove that each above mentioned change in persistence is induced by a specific critical edge in Rips complexes, which represents a local minimum of d. We use this fact to develop a theory (including interpretation) of critical edges of persistence. The obtained results include upper bounds for the rank of one-dimensional persistence and a corresponding reconstruction result. Of potential computational interest is a simple geometric criterion recognizing local minima of d that induce a change in persistence. We conclude with a proof that each locally isolated minimum of d can be detected through persistent homology with selective Rips complexes. The results of this paper offer the first interpretation of critical scales of persistent homology (obtained via Rips complexes) for general compact metric spaces.

Abstract
Aims/hypothesis
Hypomagnesaemia has been associated with insulin resistance and an increased risk of type 2 diabetes. Whether magnesium supplementation improves insulin sensitivity in people with type 2 diabetes and a low serum magnesium level is unknown.

Methods
Using a randomised, double-blind (both participants and investigators were blinded to the participants’ treatment sequences), placebo-controlled, crossover study design, we compared the effect of oral magnesium supplementation (15 mmol/day) for 6 weeks with that of matched placebo in individuals with insulin-treated type 2 diabetes (age ≥18 years, BMI 18–40 kg/m2, HbA1c <100 mmol/mol [11.3%], serum magnesium ≤0.79 mmol/l). Participants were recruited from the outpatient clinic and through advertisements. Randomisation to a treatment sequence order was done using a randomisation list. We used block randomisation and the two possible treatment sequences were evenly distributed among the trial population. The primary outcome was the mean glucose infusion rate during the final 30 min of a hyperinsulinaemic–euglycaemic clamp (i.e. M value). Secondary outcomes included variables of glucose control, insulin need, BP, lipid profile and hypomagnesaemia-related symptoms during follow-up.

Results
We recruited 14 participants (50% women, 100% White, mean ± SD age 67±6 years, BMI 31±5 kg/m2, HbA1c 58±9 mmol/mol [7.4±0.9%]) with insulin-treated type 2 diabetes. Magnesium supplementation increased both mean ± SEM serum magnesium level (0.75±0.02 vs 0.70±0.02 mmol/l, p=0.016) and urinary magnesium excretion (magnesium/creatinine ratio, 0.23±0.02 vs 0.15±0.02, p=0.005), as compared with placebo. The M value of the glucose clamp did not differ between the magnesium and placebo study arms (4.6±0.5 vs 4.4±0.6 mg kg−1 min−1, p=0.108). During the 6 weeks of treatment, continuous glucose monitoring outcomes, HbA1c, insulin dose, lipid profile and BP also did not differ, except for a lower HDL-cholesterol concentration after magnesium compared with placebo (1.14±0.08 vs 1.20±0.09 mmol/l, p=0.026). Symptoms potentially related to hypomagnesaemia were similar for both treatment arms.

Conclusions/interpretation
Despite an albeit modest increase in serum magnesium concentration, oral magnesium supplementation does not improve insulin sensitivity in people with insulin-treated type 2 diabetes and low magnesium levels.

AbstractThe Santa María and Antares Zn-Pb(-Ag) skarn deposits in the Velardeña Mining District are located in central–NW Mexico. They lie 470 m apart along the contact between Oligocene felsic intrusions and Cretaceous limestones, and were developed during prograde, retrograde, post-ore (Santa María), and late stages. Firstly, the prograde stage was formed by fluids at ~ 600 °C and 15 wt% NaCl equiv., and consists of garnet + wollastonite ± clinopyroxene and biotite ± K-feldspar assemblages. Secondly, the retrograde/ore stage was formed by fluids at 300–500 °C with salinities of 20–30 wt% CaCl2 (Santa María) and > 40 wt% NaCl equiv. (Antares). It comprises assemblages of chlorite, amphibole, epidote, calcite, scapolite, quartz, sericite, adularia, fluorite, and muscovite associated with sphalerite, pyrite, galena, pyrrhotite, arsenopyrite, chalcopyrite, and Pb-Bi-Sb sulfosalts. Thirdly, the post-ore stage was formed by fluids at ~ 400 °C and 20–30 wt.% CaCl2 and comprises poorly mineralized calcite veins. Fourthly, the late stage was formed by fluids at < 300 °C and 20–30 wt.% CaCl2 (Santa María) and ~ 15 wt% NaCl equiv. (Antares), and crystallized tetrahedrite-group minerals and pyrite + marcasite. δ18Ofluid between ~ 14‰ and 23‰ at Santa María and between ~ 12‰ and 17‰ at Antares show a less-modified magmatic affinity for mineralizing fluids at Antares; δ13Cfluid between 0‰ and –6‰ register recycling of sedimentary C. Moreover, sulfides with δ34SVCDT between –3‰ and 2‰ reveal a magmatic source for S. Altogether, these data suggest that, at Santa María, magmatic-derived fluids actively interacted with the wall rocks, whereas at Antares the fluid-rock interaction was milder. In both deposits, metal deposition was triggered by the cooling and neutralization of ore-bearing fluids with carbonate rocks. Our 40Ar/39Ar dates for adularia of ca. 37.5 Ma place the deposits within the Eocene–early Miocene metallogenetic epoch of central–NW Mexico, during which other world-class skarn-epithermal systems were emplaced (e.g., Concepción del Oro and Mazapil-Peñasquito).
Diversification and information in contests
Authors: Lemus Jorge , Temnyalov Emil 
Published: November 2023

AbstractWe study contests with technological uncertainty, where contestants can invest in different technologies of uncertain value. The principal, who is also uncertain about the value of the technologies, can disclose an informative yet noisy public signal about the merit of each technology. The signal can focus contestants’ investments into more promising technologies or increase diversification. We characterize the principal’s optimal disclosure of information about the technologies, which depends on the value of diversification, the informativeness of available signals, and the ex-ante beliefs of the likelihood of success for each technology. We also find that under some conditions offering larger prizes or having more contestants decreases the extent of information disclosure.
