摘要：
In these proceedings, we present the measurements of centrality, transverse momentum, and rapidity dependences of proton (p) and light-nuclei (d ((d) over bar), t, He-3 ((He-3) over bar), and He-4) production in Au+Au collisions at root s(NN) = 3 GeV, and isobaric (Ru+Ru and Zr+Zr) collisions at root s(NN) = 200 GeV. The compound yield ratios in central collisions at 3 GeV are found to be larger than the transport model calculations. Furthermore, the kinetic freeze-out parameters at 3 GeV show a different trend compared to those of light hadrons (pi, K, p) at higher energies.

摘要：
Current assessments of urban forest carbon storage were missing or largely underestimating their values due to limited spatial resolution. In this study, combining field plot measurements and satellite imagery, a wall-to-wall forest biomass map were generated at a very high spatial resolution (5 m) over urban areas in Wuhan City, China. Specifically, a series of characteristic metrics were extracted from Jilin-1 satellite images, including multispectral reflectances, vegetation indices, and texture features. The estimations of forest aboveground biomass from three machine learning models were evaluated at sampled field plot level. Results demonstrated that the random forest model achieved the highest accuracy using the leave-one-out cross-validation method, with a test set RMSE of 31.84 Mg/ha. However, discrepancies were observed in low biomass areas due to variations in vegetation species, leading to overestimation of lower values.

摘要：
Deep learning frameworks (DLFs) have been playing an increasingly important role in this intelligence age since they act as a basic infrastructure for an increasingly wide range of AI-based applications. Meanwhile, as multi-programming-language (MPL) software systems, DLFs are inevitably suffering from bugs caused by the use of multiple programming languages (PLs). Hence, it is of paramount significance to understand the bugs (especially the bugs involving multiple PLs, i.e., MPL bugs) of DLFs, which can provide a foundation for preventing, detecting, and resolving bugs in the development of DLFs. To this end, we manually analyzed 1497 bugs in three MPL DLFs, namely MXNet, PyTorch, and TensorFlow. First, we classified bugs in these DLFs into 12 types (e.g., algorithm design bugs and memory bugs) according to their bug labels and characteristics. Second, we further explored the impacts of different bug types on the development of DLFs, and found that deployment bugs and memory bugs negatively impact the development of DLFs in different aspects the most. Third, we found that 28.6%, 31.4%, and 16.0% of bugs in MXNet, PyTorch, and TensorFlow are MPL bugs, respectively; the PL combination of Python and C/C++ is most used in fixing more than 92% MPL bugs in all DLFs. Finally, the code change complexity of MPL bug fixes is significantly greater than that of single-programming-language (SPL) bug fixes in all the three DLFs, while in PyTorch MPL bug fixes have longer open time and greater communication complexity than SPL bug fixes. These results provide insights for bug management in DLFs.

摘要：
Motivated by the development of single image superresolution (SR) reconstruction in computer version, classic SR networks have been widely applied to the channel estimation of wireless communication system. To capture the spatial correlations in the reflection element-domain of reconfigurable intelligent surface (RIS), we propose a multi-scale supervised learning-based Laplacian pyramid wide residual network (LapWRes) to achieve the progressive reconstruction of cascaded channel in a coarse-to-fine fashion. The LapWRes can be divided vertically into feature extraction branch (FEB) and channel reconstruction branch (CRB), while it can also be viewed horizontally as multiple channel reconstruction modules (RMs) at different scales. In the FEB, the wide activation residual blocks are stacked to extract the high-frequency information of cascaded channel. In the CRB, the high-frequency and low-frequency information of cascaded channel is fused by utilizing the residual learning. Simulation results show that the LapWRes can achieve better estimation accuracy than other channel estimation schemes and faster convergence than existing SR network-based channel estimation models.

摘要：
This paper presents the design and test results of a low noise Phase Locked Loop (PLL) Application Specific Integrated Circuit (ASIC), which is designed for the data transmission system in a pixel chip for a beam monitor of the Cooling Storage Ring (CSR) external target experiment at HIRFL in China. The proposed PLL consists of a differential ring oscillator, a digital divider, a three-state phase frequency detector, a current charge pump, a second-order loop filter and current mode level buffers. A prototype PLL ASIC has been fabricated in a standard 130 nm CMOS process. The test results show that the frequency of the output clock is about 2.2 GHz with a phase noise of −90 dBc/Hz at a frequency offset of 1 MHz and a root mean square jitter of 1.15 ps. The core circuit of the PLL consumes about 30 mW under the power supply of 1.2 V.

摘要：
In this paper, we study a simultaneously transmitting and reflecting reconfigurable intelligent surface (STAR-RIS) supported simultaneous wireless information and power transfer (SWIPT) system, in which a multi-antenna access point (AP) provides power supply and communication services for multiple energy harvesting receivers (EHRs) and information decoding receivers (IDRs) respectively. To maximize the performance of the STAR-RIS, we utilize the energy splitting (ES) operation protocol in this paper. By optimizing the AP beamforming and the STAR-RIS transmission and reflection coefficients, we create a weighted sum-power maximization problem. We demonstrate that the AP can service both the IDRs and the EHRs by merely delivering information signals, which simplifies the initial optimization challenge. Then, the initial problem is split into two subproblems, and an alternative optimization method is utilized to produce high-precision suboptimal solutions to the optimization problem. Finally, we testify that the sum power received by EHRs is remarkably enhanced by the STAR-RIS-aided SWIPT systems compared with benchmark schemes in numerical results.

摘要：
A joint cascaded channel estimation framework is proposed for simultaneously transmitting and reflecting reconfigurable intelligent surfaces (STAR-RIS) systems with hardware imperfection, in which practical the hybrid-field electromagnetic wave radiation with spatial non-stationarity is investigated. By exploiting the cascaded channel correlations in user domain and STAR-RIS element domain, we propose a multi-task network (MTN) with multi-expert branches to simultaneously reconstruct the high-dimensional transmitting and reflecting channels from the observed mixture channel with noise. In the proposed MTN architecture, a learnable shrinkage module is exploited to constrict the communication noise, and self-attention mechanism-based Transformer layers are utilized to extract the non-local feature of the non-stationary cascaded channel. Numerical results show that the proposed MTN achieves superior channel estimation accuracy with less training overhead compared with existing state-of-the-art benchmarks, in terms of required pilots, computations, and network parameters.
摘要：
This work tackles two crucial challenges in representation learning-based rating prediction for engineering recommender systems. Firstly, it addresses the disparity between the ideal rating distribution and the actual scattered-grain rating distribution by incorporating a Poisson prior generative paradigm that assigns higher a priori representations to higher rating values, rather than treating all rating forms equally. Secondly, it explores the interactivity between the rating matrix and contextual information by mapping them through a lowdimensional real-valued vector, enabling a deeper understanding of users' interests and hidden interest relationships. Graph convolutional networks are employed to mitigate the impact of user preferences and enhance the estimation of interaction factors. Experimental results on six benchmark datasets demonstrate the proposed method's effectiveness in improving recommendation accuracy and novelty when replacing user decisions.

摘要：
With the continuous improvement of artificial intelligence technology, autonomous driving technology has been greatly developed. Hence automated driving software has drawn more and more attention from both researchers and practitioners. Code clone is a commonly used to speed up the development cycle in software development, but many studies have shown that code clones may affect software maintainability. Currently, there is little research investigating code clones in automated driving software. To bridge this gap, we conduct a comprehensive experience study on the code clones in automated driving software. Through the analysis of Apollo and Autoware, we have presented that code clones are prevalent in automated driving software. about 30% of code lines are involved in code clones and more than 50% of files contain code clones. Moreover, a notable portion of these code clones has caused bugs and co-modifications. Due to the high complexity of autonomous driving, the automated driving software is often designed to be modular, with each module responsible for a single task. When considering each module individually, we have found that Perception, Planning, Canbus, and Sensing modules are more likely to encounter code clones, and more likely to have bug-prone and co-modified clones. Finally, we have shown that there exist cross-module clones to propagate bugs and co-modifications in different modules, which undermine the software's modularity.
摘要：
Space mapping (SM) is widely used in electromagnetic (EM) optimization due to its fast characteristics. For waveguide devices, mesh morphing-embedded space mapping helps speed up electromagnetic optimization of coarse model. In this paper, the recent advances in mesh morphing-embedded space mapping is reviewed from the aspects of parallel SM and coarse- and fine-mesh SM based on mesh deformation. The current mesh morphing technology is not limited to wave-guides with rectangular structures, but also waveguides with arc structures can be meshed better with mesh morphing. Two microwave instances of different structures will serve as proof of the aforementioned techniques.

摘要：
We present the first lattice QCD results of the second-order fluctuations of, and correlations among net-baryon number, electric charge, and strangeness in (2+1)-flavor lattice QCD in the presence of a background magnetic field with physical pion mass m(pi) = 135 MeV. To mimic the magnetic field strength produced in the early stage of heavy-ion collision experiments, we use 6 different values of the magnetic field strength up to similar to 10 m(pi)(2). We find that the correlations between baryon number and electric charge along the transition line are substantially affected by magnetic fields in the current eB window, which could be useful for probing the existence of a magnetic field in heavy-ion collision experiments.

摘要：
Pseudo-labels are popular in semi-supervised facial expression recognition. Recent methods usually exploit the confidence as the criterion for pseudo-label generation, and utilize the high-confidence pseudo-labels as the ground-truth for training. However, high confidence cannot guarantee the correctness of pseudo-labels. False pseudo-labels can weaken the feature discrimination and degrade recognition performance. In this paper, we propose a Critical Feature Refinement Network (CFRN) to alleviate the interference of false pseudo-labels on the model performance. Specially, a feature dropout module and a feature emphasis module are proposed to improve the feature discrimination of CFRN. Then, a mean-absolute error loss is further exploited to improve the robustness against false pseudo-labels. Experimental results on three challenging datasets RAF-DB, SFEW and Affectnet demonstrate that the proposed CFRN outperforms the state-of-the-art methods.

摘要：
We employ the QCD kinetic theory, including next-to-leading (NLO) order corrections in coupling constant, to study the evolution of weakly coupled non-Abelian plasmas towards thermal equilibrium. For two characteristic far-from-equilibrium systems with either under- or over-occupied initial conditions, the NLO corrections remain well under control for a wide range of couplings, and the overall effect of NLO corrections is a reduction in the time required for thermalization.
摘要：
The Three Parallel Rivers Basin (TPRB) is a global biodiversity hotspot in the southeast of Qinghai-Tibet Plateau. The vegetation ecosystem has undergone significant changes due to global environmental changes, necessitating the long-term and fine-scale monitoring. The Hi-GLASS FVC product, derived from Landsat 8 data, has a fine spatial resolution of 30 m, but spatial gaps caused by clouds and shadows are prevalent. To address this issue, a 16-day, 30 m resolution FVC dataset was generated from 2000 to 2018 for the TPRB by fusing Hi-GLASS FVC and GLASS FVC time-series data. Combining the annual average FVC and growing-season average FVC, trend analysis of vegetation cover was conducted at two different spatial resolutions (30m and 500m) using the Sen's slope and Mann-Kendall test at a 95% confidence level. The results indicated that more areas exhibited significant improvements in vegetation than degradation. The improvements were characterized by the increase of the annual average FVC as well as the growing-season FVC for two decades. This study provides scientific supports for the development of ecological conservation plans in the TPRB region.
