摘要:
This paper investigates a Simultaneously Transmitting and Reflecting Reconfigurable Intelligent Surface (STAR-RIS)-assisted unmanned aerial vehicle (UAV)-enabled outdoor-to-indoor (O2I) wireless powered communication network (WPCN), in which the UAV avoids flying over the indoor no-fly zone (NFZ). In the downlink energy transfer (DET) stage, the energy-constrained STAR-RIS and the O2I Internet of Things (IoT) devices harvest energy from the radio frequency (RF) signals of the UAV to self-sustain its operation. In the uplink information transmission (UIT) stage, the IoT devices transmit information to the UAV using the harvested energy, assisted by the STAR-RIS. We introduce the STAR-RIS energy splitting (ES) and time switching (TS) operating protocols in the DET and UIT stages, respectively, to maximize the harvested downlink energy and the achievable uplink sum-rate. Further, an alternating optimization (AO) algorithm based on the penalty method and successive convex approximation (SCA) technology is proposed to solve the resulting highly-coupled non-convex optimization problems, in which the UAV trajectory based on the UAV power consumption model, resource allocation of the O2I IoT devices, and beamforming vectors of the STAR-RIS are jointly optimized. Finally, numerical results demonstrate that our proposed scheme can achieve significant system sum-rate gains that are better than other baseline schemes.

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:
Ternary copper halides, such as Cs3Cu2I5, as an emerging class of nontoxic alternatives to lead halide perovskites, have drawn extensive attention in the X-ray detection field due to their efficient self-trapped exciton emissions. However, the light yield far below the theoretical limit seriously hinders the high-resolution X-ray detection application of copper halide scintillators. Herein, Cs3Cu2I5:K+ scintillation films and single crystals with enhanced photoluminescence (PL) and radiation luminescence (RL) were first obtained by adjusting the doping concentration of K+ ions in the 0-8 at% range. The substitution of Cs+ by doping K+ compacted the adjacent [Cu2I5](3-) dimer groups, resulting in a stronger exciton-photon coupling strength. Therefore, Cs3Cu2I5:K+ single crystals exhibited a stronger RL emission under X-ray excitation, and their light output was about 49.6% higher than that of the pure Cs3Cu2I5, with an accelerated scintillation decay time (330 to 241 ns). Benefiting from these advantages, X-ray detectors based on hydrophobic polymethyl methacrylate (PMMA)-coated Cs3Cu2I5:K+ flexible films could deliver a higher X-ray imaging resolution of 11.7 lp mm(-1)@MTF = 0.2 in comparison with the commercial gadolinium oxysulfide (GOS)-based detectors (6.2 lp mm(-1)@MTF = 0.2). This work provides insights for the design of metal halides for use in low-cost and high-resolution flexible X-ray imaging systems.

摘要:
Biological processes such as transcription, repair, and regulation require interactions between DNA and proteins. To unravel their functions, it is imperative to determine the high-resolution structures of DNA-protein complexes. However, experimental methods for this purpose are costly and technically demanding. Consequently, there is an urgent need for computational techniques to identify the structures of DNA-protein complexes. Despite technological advancements, accurately identifying DNA-protein complexes through computational methods still poses a challenge. Our team has developed a cutting-edge deep-learning approach called DDPScore that assesses DNA-protein complex structures. DDPScore utilizes a 4D convolutional neural network to overcome limited training data. This approach effectively captures local and global features while comprehensively considering the conformational changes arising from the flexibility during the DNA-protein docking process. DDPScore consistently outperformed the available methods in comprehensive DNA-protein complex docking evaluations, even for the flexible docking challenges. DDPScore has a wide range of applications in predicting and designing structures of DNA-protein complexes. Biological processes such as transcription, repair, and regulation require interactions between DNA and proteins.
摘要:
Herein, we aimed to solve the problem of difficulty in filtering the noise components in the monitoring of strain on wind turbine blades using fiber bragg grating, a denoising method based on parameter-optimized variational mode decomposition (VMD) is proposed. This method uses the minimum envelope entropy as the fitness function and the slime mould algorithm for self-adaptive optimization to find the optimal combination of modal decomposition components K and the quadratic penalty factor alpha of VMD. The optimized VMD was used to decompose the strain data of wind turbine blades over time into K intrinsic mode components, and the noise mode was removed using the sample entropy to obtain the effective signal. The proposed method was compared to ensemble empirical mode decomposition and complementary ensemble empirical mode decomposition using the simulated signals and engineering data. The experimental results show that the proposed method can effectively remove noise from the strain data of wind turbine blades and has better denoising performance than the other two methods, which provides a reliable basis for analyzing the strain data of wind turbine blades.

摘要:
The magnetic fields in heavy-ion collisions are important ingredients for many interesting phenomena, such as the chiral magnetic effect, the chiral magnetic wave, the directed flow v1 of D0 mesons, and the splitting of the spin polarization of the Lambda/(Lambda) over bar over bar . Quantitative studies of these phenomena, however, suffer from limited understanding of the dynamical evolution of these fields in the medium created by the collisions, which remains a critical and challenging problem. The initial magnetic fields from the colliding nuclei decay very fast in the vacuum but their lifetime could be extended through medium response due to electrically conducting quarks and antiquarks. Here we perform a detailed analysis of such medium effect on the dynamical magnetic fields by numerically solving Maxwell's equations concurrently with the expanding medium described by viscous hydrodynamics, under the assumption of negligible back reaction of the fields on the fluid evolution. Our results suggest a considerable enhancement of late time magnetic fields, the magnitude of which depends sensitively on the fireball expansion as well as the medium electric conductivity both before and during hydrodynamic stage.

摘要:
Motivated by recent experimental LHC measurements on the forward inclusive jet productions and based on our previous calculations on forward hadron productions, we calculate a single inclusive jet cross section in pA collisions at forward rapidity within the color glass condensate framework up to the next-to -leading order. Moreover, with the application of a jet algorithm and proper subtraction of the rapidity and collinear divergences, we further demonstrate that the resulting next-to-leading-order hard coefficients are finite. In addition, in order to deal with the large logarithms that can potentially spoil the convergence of the perturbative expansion and improve the reliability of the numerical predictions, we introduce the collinear jet function and the threshold jet function and resum these large logarithms hidden in the hard coefficients.

magnetic target localization;magnetic gradient tensor;localization dead zone;eigenvector constraints
摘要:
Magnetic target localization using the magnetic gradient tensor (MGT) plays a significant role in underwater localization. However, this method inherently has a localization dead zone, which presents challenges for real-world applications. This paper delves into the root cause of this dead zone, identifying the non-invertibility of the MGT when the magnetic moment vector is orthogonal to the position vector from the target to the observation point. To tackle this issue, a method based on the eigenvector constraints is proposed. By constructing an objective function with eigenvector constraints and leveraging the property that its gradient at the observation point is zero, we derive an equivalent expression for the inverse of MGT that always holds and further develop a dead-zone-free localization method. To validate the robustness and efficacy of the proposed localization method, a comparative analysis with other methods is conducted. Simulation results in a 10 m × 10 m area under Gaussian noise demonstrate the proposed method’s capability to eliminate the dead zone and achieve an average localization error of 0.032 m. Experimental results further demonstrate that the proposed method eliminates the localization dead zone and exhibits greater robustness than the dominant method in the normal region. In summation, this paper provides an effective method for eliminating localization dead zone, offering a more stable and reliable method for magnetic target localization in practice.

摘要:
Mach cones are expected to form in the expanding quark-gluon plasma (QGP) when energetic quarks and gluons traverse the hot medium at a velocity faster than the speed of sound in high-energy heavy-ion collisions. The shape of the Mach cone and the associated diffusion wake are sensitive to the initial jet production location and the propagation direction of the parton shower relative to the radial flow because of the distortion caused by the collective expansion of the QGP and the large density gradient. The shape of jet-induced Mach cones and their distortions in heavy-ion collisions provide a unique and direct probe of the dynamical evolution and the equation of state of QGP. However, it is difficult to identify the Mach cone and the diffusion wake in current experimental measurements of final hadron distributions because they are averaged over all possible initial jet production locations and parton-shower propagation directions. To overcome this difficulty, we develop a deep learning assisted jet tomography which uses the full information of the final hadrons from jets to localize the initial jet production positions. This method can help to constrain the initial regions of jet production in heavy-ion collisions and enable a differential study of Mach-cones with different path lengths and orientations relative to the radial flow of the QGP in heavy-ion collisions.

摘要:
The interpretation of cosmic antiproton flux measurements from space-borne experiments is currently limited by the knowledge of the antiproton production cross-section in collisions between primary cosmic rays and the interstellar medium. Using collisions of protons with an energy of 6.5
$$\,\text {Te\hspace{-1.00006pt}V}$$
incident on helium nuclei at rest in the proximity of the interaction region of the LHCb experiment, the ratio of antiprotons originating from antihyperon decays to prompt production is measured for antiproton momenta between 12 and
$$110\,\text {Ge\hspace{-1.00006pt}V\!/}c $$
. The dominant antihyperon contribution, namely
$${\overline{\varLambda }} \rightarrow {\overline{{p}}} {{\pi } ^+} $$
decays from promptly produced
$$\overline{\varLambda }$$
particles, is also exclusively measured. The results complement the measurement of prompt antiproton production obtained from the same data sample. At the energy scale of this measurement, the antihyperon contributions to antiproton production are observed to be significantly larger than predictions of commonly used hadronic production models.

摘要:
A transfer learning method, Domain Adversarial Neural Network (DANN), is introduced to study the phase transition of two-dimensional q-state Potts model. With the DANN, we only need to choose a few labeled configurations automatically as input data, then the critical points can be obtained after training the algorithm. By an additional iterative process, the critical points can be captured to comparable accuracy to Monte Carlo simulations as we demonstrate it for q = 3,4, 5, 7 and 10. The type of phase transition (first or second-order) is also determined at the same time. Meanwhile, for the second -order phase transition at q = 3, we can calculate the critical exponent & nu; by data collapse. Furthermore, compared to the traditional supervised learning, we found the DANN to be more accurate with lower cost.& COPY; 2023 Elsevier B.V. All rights reserved.

摘要:
A combined amplitude analysis is performed for the decays B0-+ D0D thorn s & pi;- and B thorn -+ D-D thorn s & pi; thorn , which are related by isospin symmetry. The analysis is based on data collected by the LHCb detector in proton -proton collisions at center-of-mass energies of 7, 8, and 13 TeV. The full data sample corresponds to an integrated luminosity of 9 fb-1. Two new resonant states with masses of 2.908 ⠂ 0.011 ⠂ 0.020 GeV and widths of 0.136 ⠂ 0.023 ⠂ 0.013 GeV are observed, which decay to D thorn s & pi; thorn and D thorn s & pi;- respectively. The former state indicates the first observation of a doubly charged open-charm tetraquark state with minimal quark content 1/2cs over bar ud over bar ⠃, and the latter state is a neutral tetraquark composed of 1/2cs over bar u over bar d ⠃ quarks. Both states are found to have spin-parity of 0 thorn , and their resonant parameters are consistent with each other, which suggests that they belong to an isospin triplet.
