摘要：
Ammonium‐ion batteries: NH4+‐rich nickel hexacyanoferrate was successfully synthesized through a facile one‐pot method. It exhibits excellent electrochemical performances as cathode material for ammonium‐ion batteries which can be attributed to reversible redox reaction and durable structure. Abstract Rechargeable aqueous batteries based on ammonium‐ion (NH4+) redox reactions shows great potential for large‐scale energy‐storage due to its plentiful supplies, environmental friendliness, intrinsic security, and sustainability. Prussian blue analogues (PBAs) are regarded to be one of the most promising electrode materials owning to high energy storage density, ease of synthesis, and excellent electrochemical performances. However, the synthesis of ammonium rich Prussian blue analogues is too complicated. Herein, a one pot synthesis of NH4+‐rich nickel hexacyanoferrate (NNiHCF) is developed and the NH4+ storage chemistry is investigated. NNiHCF cathode is coupled with an activated carbon (AC) anode and (NH4)2SO4 aqueous electrolyte to assemble ammonium‐ion batteries. The aqueous full cell demonstrates good electrochemical performance, such as 50.2 mAh g−1 at the current rate of 2 C, and 60 % capacity retention in 5000 cycles. Furthermore, the fundamental characteristics of the reversible redox reaction and the durable structure of NNiHCF are revealed by X‐ray diffraction (XRD) and electrochemical measurements. This work proposes a facile method for the synthesis of ammonium‐rich Prussian.

摘要：
A study of B-c(+) -> chi(c) pi(+) decays is reported using proton-proton collision data, collected with the LHCb detector at centre-of-mass energies of 7, 8, and 13TeV, corresponding to an integrated luminosity of 9 fb(-1). The decay B-c(+) -> chi(c2)pi(+) is observed for the first time, with a significance exceeding seven standard deviations. The relative branching fraction with respect to the B-c(+) -> J/psi pi(+) decay is measured to be BBc+ ->chi c2 pi+/BBc+ -> (J/psi pi+) = 0.37 +/- 0.06 +/- 0.02 +/- 0.01, where the first uncertainty is statistical, the second is systematic, and the third is due to the knowledge of the chi(c2) -> J/psi gamma branching fraction. No significant B-c(+) -> chi(+)(c1 pi) signal is observed and an upper limit for the relative branching fraction for the B-c(+) -> chi(c1)pi(+) and B-c(+) -> chi(c2)pi(+) decays of BBc+ ->chi c1 pi+/BBc+ -> chi(c2)pi(+) < 0.49 is set at the 90% confidence level.
摘要：
In this paper, we construct a bounce inflation cosmological scenario in the framework of the modified symmetric teleparallel gravity, namely f(Q) theory, and investigate the tensor perturbations therein. As is well-known, the tensor perturbations generated in the very early Universe (inflation and pre-inflation regions) can account for the primordial gravitational waves (PGWs) that are to be detected by the next generation of GW experiments. We discuss the stability condition of the tensor perturbations in the bounce inflation process and investigate in detail the evolution of the perturbation variable. The general form of the tensor power spectrum is obtained both for large as well as small scale modes. As a result, we show both kinds of modes (short or long wavelength modes), and the tensor spectrum may get a positive tilt in the parametric range where the tensor perturbation proves to be stable-this interestingly hints an enhancement of gravitational waves' amplitude in the background of the f(Q) bounce-inflation scenario. Moreover, we study the LQC-like scenario as a specific case of our model, in which, the primordial tensor power spectrum turns out to be nearly scale-invariant on both small and large scales.

摘要：
Chemodynamic therapy (CDT) is a promising cancer treatment strategy. However, mild acidic pH, insufficient H(2)O(2) content, and overexpressed glutathione (GSH) in the tumor microenvironment (TME) severely impair CDT efficiency. In this study, a novel therapeutic nanosystem (Cu/ZIF-8/Vc-Ca/HA) was constructed for H(2)O(2) self-supply and GSH depletion co-enhanced CDT. Typically, calcium ascorbate (Vc-Ca) loaded on the surface of Cu(2+)-doped ZIF-8 (Cu/ZIF-8) was designed as an original source for H(2)O(2) generation, and a hyaluronic acid (HA) shell was subsequently coated to act as a tumor-targeted "guide" and protective layer. Along with the HA shell disintegrated in the TME, exposed Cu/ZIF-8/Vc-Ca dissociated in the tumor acidic microenvironment, thus triggering the release of Vc-Ca and Cu(2+). Vc-Ca selectively produced H(2)O(2) in tumor cells, which provided abundant H(2)O(2) for boosting Fenton-like reactions. Meanwhile, the released Cu(2+) could get converted into Cu(+) by consuming excess intracellular GSH, which could reduce the tumor antioxidant capability of the nanosystem. Moreover, byproduct Cu(+) reacted with abundant H(2)O(2) by a highly efficient Fenton-like reaction to generate toxic ˙OH. Biological assays indicated that the Cu/ZIF-8/HA@Vc-Ca nanosystem showed significant anticancer activity by enhancing the CDT process. This study may provide a new strategy for improving the effectiveness of CDT.

摘要：
Hybrid quantum systems based on magnons in magnetic materials have made significant progress in the past decade. They are built based on the couplings of magnons with microwave photons, optical photons, vibration phonons, and superconducting qubits. In particular, the interactions among magnons, microwave cavity photons, and vibration phonons form the system of cavity magnomechanics (CMM), which lies in the interdisciplinary field of cavity QED, magnonics, quantum optics, and quantum information. Here, we review the experimental and theoretical progress of this emerging field. We first introduce the underlying theories of the magnomechanical coupling, and then some representative classical phenomena that have been experimentally observed, including magnomechanically induced transparency, magnomechanical dynamical backaction, magnon-phonon cross-Kerr nonlinearity, etc. We also discuss a number of theoretical proposals, which show the potential of the CMM system for preparing different kinds of quantum states of magnons, phonons, and photons, and hybrid systems combining magnomechanics and optomechanics and relevant quantum protocols based on them. Finally, we summarize this review and provide an outlook for the future research directions in this field.

opportunistic mobile networks;energy-efficient;geographic information
摘要：
Opportunistic mobile networks, as an important supplement to the traditional communication methods in unique environments, are composed of mobile communication devices. It is a network form that realizes message transmission by using the opportune encounter of these mobile communication devices. Consequently, mobile communication devices necessitate periodic contact detection in order to identify potential communication opportunities, thereby leading to a substantial reduction in the already limited battery life of such devices. Previous studies on opportunistic networks have often utilized geographic information in routing design to enhance message delivery rate. However, the significance of geographic information in energy conservation has been overlooked. Furthermore, previous research on energy-efficient routing has lacked diversification in terms of the methods employed. Therefore, this paper proposes a dynamic co-operative energy-efficient routing algorithm based on geographic information perception (DCEE-GIP) to leverage geographic information to facilitate dynamic co-operation among nodes and optimize node sleep time through probabilistic analysis. The DCEE-GIP routing and other existing algorithms were simulated using opportunistic network environment (ONE) simulation. The results demonstrate that DCEE-GIP effectively extends network service time and successfully delivers the most messages. The service time of DCEE-GIP increased by 8.05 similar to 31.11%, and more messages were delivered by 14.82 similar to 115.9%.

摘要：
Nucleosomes represent hubs in chromatin organization and gene regulation and interact with a plethora of chromatin factors through different modes. In addition, alterations in histone proteins such as cancer mutations and post-translational modifications have profound effects on histone/nucleosome interactions. To elucidate the principles of histone interactions and the effects of those alterations, we developed histone interactomes for comprehensive mapping of histone-histone interactions (HHIs), histone-DNA interactions (HDIs), histone-partner interactions (HPIs) and DNA-partner interactions (DPIs) of 37 organisms, which contains a total of 3808 HPIs from 2544 binding proteins and 339 HHIs, 100 HDIs and 142 DPIs across 110 histone variants. With the developed networks, we explored histone interactions at different levels of granularities (protein-, domain- and residue-level) and performed systematic analysis on histone interactions at a large scale. Our analyses have characterized the preferred binding hotspots on both nucleosomal/linker DNA and histone octamer and unraveled diverse binding modes between nucleosome and different classes of binding partners. Last, to understand the impact of histone cancer-associated mutations on histone/nucleosome interactions, we complied one comprehensive cancer mutation dataset including 7940 cancer-associated histone mutations and further mapped those mutations onto 419,125 histone interactions at the residue level. Our quantitative analyses point to histone cancer-associated mutations' strongly disruptive effects on HHIs, HDIs and HPIs. We have further predicted 57 recurrent histone cancer mutations that have large effects on histone/nucleosome interactions and may have driver status in oncogenesis.

摘要：
Waveguides are fundamental components in communication systems. However, they suffer from reflection and scattering losses at sharp routes or defects. The breakthrough in developing topological photonic crystals (PhCs) provides promising solutions to robust signal transmission. In this work, we propose a new mechanism for protecting wave-guiding modes by decorating the boundaries of a conventional waveguide with valley-Hall PhCs. This special layout enables the robust propagation of conventional transverse electric (TE) waves against defects and bends. Moreover, the proposed waveguide is compatible with the substrate-integrated waveguide (SIW). High-efficient mode conversion from the SIW to the proposed waveguide is achievable. By leveraging the idea of topology to conventional waveguides, we provide a powerful and practical tool that can largely improve the performance of microwave and millimeter-wave integrated circuits while reserving the features of wave-guiding modes.

摘要：
Abstract This paper proposes a new Padé via Arnoldi algorithm with single‐size matrix simplification for electromagnetic (EM) fast frequency sweep. New equations are derived to reduce the double‐size system matrix to single‐size system matrix. We also propose a systematic algorithm to calculate S‐parameters using the simplified single‐size system matrix. Using the proposed algorithm, the EM responses can be obtained with the same accuracy while consuming much less time compared with that using the existing double‐size matrix Padé via Lanczos. The proposed algorithm is demonstrated by two microwave examples.
摘要：
Zinc metal batteries (ZMBs) have received a lot of attention due to their high capacity, proper redox potential and low cost. However, zinc anodes suffer from serious dendritic problems and side reactions, resulting in poor cycling stability of zinc ion batteries. Herein, organic additive trimethyl phosphate (TMP) is introduced into inexpensive ZnSO4 electrolyte to stabilize Zn anode. TMP exhibits bifunctional properties in this cost-effective electrolyte system. It prefers adsorbing on (002) plane of zinc which leads to preferential crystal growth and uniform zinc deposition. Moreover, TMP can reshape the original hydrogen bond network, regulate the solvation structure and inhibit the parasitic reaction generated by water. As a result, the zinc anode with TMP addition could maintain 2000 h at a current density of 0.5 mA cm−2 which is superior to bare zinc anode. When paired with V2O5 cathode, the full cell also shows excellent cyclic performance. Such a low-cost bifunctional additive would offer a strategy for stabilizing Zn plating/stripping behaviors and suppressing side reactions in mild aqueous electrolyte.
摘要：
A low-profile coding metasurface based on beam diffusion and absorption is proposed, which can be applied for broadband Radar Cross section (RCS) reduction. Through inserting resistors into the polarization conversion element, the proposed unit cell can convert a portion of the electromagnetic wave to ohmic loss as well as retain polarization conversion. Subsequently, the power loss and surface current were used to explain the mechanism of absorption and polarization conversion, and the arrangement of the elements was optimized using a simulated annealing algorithm. Furthermore, both the simulated and measured results have shown that the RCS reduction is greater than 10 dB at 6.7-19.3 GHz (the relative bandwidth is 96.9%), and the metasurface still maintains great characteristics at 45 degrees incidence. Thanks to the proposed metasurface offer advantages such as fewer resistors, a wider bandwidth for RCS reduction, an ultra-thin profile (0.066 lambda L, where lambda L represents the longest wavelength), a stable incident angle, and a more uniform scattering of energy, it can be used in electromagnetic stealth for large targets.
摘要：
This paper proposes a bifunctional linear-to linear polarization converter with a sandwich structure that enables transmissive and reflective polarization conversions in different operating bands, simultaneously. The unit cell of the converter metasurface comprises an S-shaped wire, a dielectric slab, and an S-shaped slot, where the S-shaped wire and slot have complementary structures and a 30 degrees difference in orientation. When an x-polarized electromagnetic wave is incident on the proposed metasurface, most of the transmitted wave is y-polarized in the frequency range of 7.07 GHz to 7.46 GHz, while most of the reflected wave is y-polarized in the frequency range of 16.59 GHz to 16.91 GHz. The physical mechanism underlying these two types of polarization conversions was analyzed based on the surface current, and electric field distributions. Notably, the transmissive polarization conversion was primarily attributed to magnetic resonance, while its reflective counterpart was ascribed to electric resonance. In addition, the Jones vector and Stokes parameters were analyzed thereby elucidating the polarization characteristics of the proposed metasurface. Furthermore, simulation data demonstrated excellent agreement with the measured results of polarization conversion. The designed metasurface will promote subsequent research on bifunctional polarization converters.

摘要：
In this study, we utilize the complexity-action duality to study the evolution of complexity in a holographic QCD model at finite temperature and chemical potential. By inserting a fundamental string as a probe, we investigated the properties of complexity growth in this Einstein-Maxwell-scalar gravity system, which is affected by the string velocity, chemical potential, and temperature. Our results show that the complexity growth is maximized when the probe string is stationary, and it decreases as the velocity of the string increases. When the string approaches relativistic velocities, the complexity growth always increases monotonically with respect to the chemical potential. Furthermore, we find that the complexity growth can be used to identify phase transitions and crossovers in the model.

摘要：
We propose a scheme to generate nonreciprocal entanglement between an yttrium iron garnet (YIG) sphere and two nitrogen -vacancy -center ensembles by magnon Kerr effects in a transmission -line resonator. By driving the YIG sphere appropriately, strong Kerr nonlinearities emerge and then induce magnon parametric amplification and magnon frequency shift, resulting in the appearance of optimal entanglements. Depending on the direction of the bias magnetic field, macroscopic nonreciprocal entanglement is realized in this all -solid-state quantum system, which may find potential applications in chiral quantum information processing.
摘要：
The main goal of this paper is to investigate the predefined-time sliding mode control and synchronization of uncertain hyperchaotic systems and its application in secure communication. Firstly, a novel predefined-time sliding surface is designed. Then a predefined-time sliding mode controller is proposed for uncertain hyperchaotic systems, which can guarantee synchronization of the master-slave system within a predefined time in the presence of parameter uncertain and external disturbance. Specially, the settling time, as a part of control parameters, can be predefined as needed independent of initial conditions. Furthermore, the validity of the proposed approach is proved by Lyapunov stability theory. Finally, comparative tests and image encryption application are given to show advantages of the proposed method.

摘要：
Zincophilic property and high electrical conductivity are both very important parameters to design novel Zn anode for aqueous Zn-ion batteries (AZIBs). However, single material is difficult to exhibit zincophilic property and high electrical conductivity at the same time. Herein, originating from theoretical calculation, a zincophilic particle regulation strategy is proposed to address these limitations and carbon coated Na3V2(PO4)3 is taken as an example to be a protective layer on zinc metal (NVPC@Zn). Na3V2(PO4)3 (NVP) is a common cathode material for Zn-ion batteries, which is zincophilic. Carbon materials not only offer an electron pathway to help Zn deposition onto NVPC surface, but also enhance the zinc nucleophilicity of Na3V2(PO4)3. Hence, this hybrid coating layer can tune zinc deposition and resist side reactions such as hydrogen generation and Zn metal corrosion. Experimentally, a symmetrical battery with NVPC@Zn electrode displays highly reversible plating/stripping behavior with a long cycle lifespan over 1800 h at 2 mA cm-2, much better than carbon and Na3V2(PO4)3 solely modified Zn electrodes. When the Na3V2(PO4)3 is replaced with zincophobic Al2O3 or zincophilic V2O3, the stability of the modified zinc anodes is also prolonged. This strategy expands the option of zincophilic materials and provides a general and effective way to stabilize the Zn electrode.

摘要：
In radio frequency (RF) and microwave design optimization, electromagnetic (EM) simulation is crucial yet time-consuming. Solving extensive system equations is computationally expensive for finite-element method (FEM)-based EM simulation. In addition, during optimization, changes to the EM structure are often incremental, leading to inefficiencies in generating and solving new FEM system equations. To address this situation, this article proposes a novel design space decomposition (DSD) technique to rapidly calculate the EM response ( $S$ -parameter) of EM waveguide structures featuring newly optimized topologies. The proposed DSD technique is to segment the variable in the whole design space into several small variables in subspaces. Specifically, the FEM system matrix is decomposed into a constant part and a variable part, where the variable part can be further decomposed into a diagonal block matrix. Subsequently, a novel algorithm is developed to expedite the calculation of the EM response when modifications are applied to the diagonal block matrix within the variable part. With the proposed algorithm, the size of the small matrix remains independent of the number of subspaces, maintaining its smallest size consistently. This streamlined approach facilitates rapid calculations. The proposed technique negates the need to compute the entire, extensive system matrix, thereby greatly reducing the computational burden. Consequently, the proposed technique expedites the overall EM topology optimization. The efficiency of the proposed method is demonstrated through two microwave examples.
