摘要：
A model-independent study of CP violation in B-0 -> DK (*0) decays is presented using data corresponding to an integrated luminosity of 9 fb(-1) collected by the LHCb experiment at centre-of-mass energies of v s = 7, 8 and 13TeV. The CKM angle. is determined by examining the distributions of signal decays in phase-space bins of the self-conjugate D. K(S)(0)h(+) h(-) decays, where h = p, K. Observables related to CP violation are measured and the angle. is determined to be. = (49+22 -19).. Measurements of the amplitude ratio and strong-phase difference between the favoured and suppressed B-0 decays are also presented.

摘要：
The first measurements of K-& lowast;(892)(0 )resonance production as a function of charged-particle multiplicity in Xe-Xe collisions at root sNN=5.44 TeV and pp collisions at root s=5.02 TeV using the ALICE detector are presented. The resonance is reconstructed at midrapidity (|y| < 0.5) using the hadronic decay channel K*(0) -> K +/-pi -/+. Measurements of transverse-momentum integrated yield, mean transverse-momentum, nuclear modification factor of K*(0), and yield ratios of resonance to stable hadron (K*(0)/K) are compared across different collision systems (pp, p-Pb, Xe-Xe, and Pb-Pb) at similar collision energies to investigate how the production of K*(0) resonances depends on the size of the system formed in these collisions. The hadronic rescattering effect is found to be independent of the size of colliding systems and mainly driven by the produced charged-particle multiplicity, which is a proxy of the volume of produced matter at the chemical freeze-out. In addition, the production yields of K*(0) in Xe-Xe collisions are utilized to constrain the dependence of the kinetic freeze-out temperature on the system size using the hadron resonance gas-partial chemical equilibrium model.

摘要：
With a data sample corresponding to an integrated luminosity of 11.5 fb(-1) collected with the BESIII detector operating at the BEPCII storage ring, for the first time the light hadron decay chi(c1()3872)->pi(+)pi(-)eta is searched for. While no significant signal is observed, the upper limits at the 90% confidence level for sigma[e(+)e(-)->gamma chi(c1)(3872)]B[chi(c1)(3872)->pi(+)pi(-)eta] at center of mass energies from 4.13 GeV to 4.34 GeV are determined. By normalizing to the chi(c1)(3872)->pi(+)pi(-)J/psi decay channel, a 90% confidence level upper limit for the branching fraction ratio R=B[chi(c1)(3872)->pi(+)pi(-)eta]/B[chi(c1)(3872)->pi(+)pi(-)J/psi]<0.12 is given. These measurements provide important inputs for understanding the internal structure of the chi(c1)(3872) resonance

摘要：
A light scalar X-0 or vector X-1 particles have been introduced as a possible explanation for the (g - 2)(mu) anomaly and dark matter phenomena. Using (8.998 +/- 0.039) x 10(9) J=psi events collected by the BESIII detector, we search for a light muon philic scalar X-0 or vector X-1 in the processes J=psi -> mu(+)mu X--(0,1) with X-0,X-1 invisible decays. No obvious signal is found, and the upper limits on the coupling g'(0,1) between the muon and the X-0,X-1 particles are set to be between 1.1 x 10(-3) and 1.0 x 10(-2) for the X-0,X-1 mass in the range of 1 < M(X-0,X-1) < 1000 MeV=c(2) at 90% credibility level.
摘要：
Mining and predicting college students behaviors from fine-grained spatial-temporal campus activity data play key roles in the academic success and personal development of college students. Most of the existing behavior prediction methods use shallow learning algorithms such as statistics, clustering, and correlation analysis approaches, which fail to mine the long-term spatial-temporal dependencies and semantic correlations from these fine-grained campus data. We propose a novel multi-fragment dynamic semantic spatial-temporal graph convolution network, named the MFDS-STGCN, on the basis of a spatial-temporal graph convolutional network (STGCN) for the automatic prediction of college students' behaviors and abnormal behaviors. We construct a dataset including 7.6 million behavioral records derived from approximately 400 students over 140 days to evaluate the effectiveness of the prediction model. Extensive experimental results demonstrate that the proposed method outperforms multiple baseline prediction methods in terms of student behavior prediction and abnormal behavior prediction, with accuracies of 92.60% and 90.84%, respectively. To further enable behavior prediction, we establish an early warning management mechanism. Based on the predictions and analyses of Big Data, education administrators can detect undesirable abnormal behaviors in time and thus implement effective interventions to better guide students' campus lives, ultimately helping them to more effectively develop and grow.

摘要：
Animal-mediated seed dispersal is very important for plant population regeneration and the stability of forest ecosystems. Seed size and cache density are important factors for seed dispersal, but we still know little about seed size selection at different cache densities. Here, we conducted field experiments in a Larix principis-rupprechtii plantation in the Liupan Mountains in Ningxia province to investigate the effects of tag-marked Quercus wutaishanica seeds of different sizes and cache densities on predation and the scatter-hoarding behavior of rodents. The results showed lower proportions of intact in situ (IIS) and eaten in situ (EIS) large seeds than small seeds at all levels of cache density, with the exception of IIS seeds at a 6.25 seed center dot m(-2) cache density. A higher proportion of small seeds were eaten after removal (EAR), but a higher proportion of large seeds were scatter-hoarded (SH) by rodents at most cache densities. Furthermore, rodents preferentially removed large seeds farther away for eating or scatter-hoarding. The IIS and EIS proportions of both large and small seeds declined, but the proportion of the two types of seeds that were EAR fluctuated, increasing with increasing cache density. Rodents preferred to increase the proportion of scatter-hoarding of large seeds with increasing cache density, whereas the proportion of scatter-hoarding of small seeds was maximized at a cache density of 6.25 seed center dot m(-2). Both the eaten distance after removal (EDAR) and scatter-hoarded distance (SHD) increased with increasing cache density. These results suggest that large seeds are more likely to be scatter-hoarded and removed to longer distances than small ones. Rodents tended to reduce the seed proportion of EIS seeds and increased the proportion of seeds EAR and SH, and accordingly increased EDAR and SHD with increasing cache density. This study provides some scientific basis for animal-mediated seed dispersal.

摘要：
The core of harmonic detection is the recognition and extraction of each order harmonic in the signal. The current detection methods are seriously affected by the fence effect and spectrum aliasing, which brings great challenges to the detection of each order harmonic in the signal. This paper proposes an efficient harmonic detection neural network based on all-phase processing. It is based on three crucial designs. First, a harmonic signal-processing module is developed to ensure phase invariance and establish the foundation for subsequent modules. Then, we constructed the backbone network and utilized the feature-extraction module to extract deep abstract harmonic features of the target. Furthermore, a channel attention mechanism is also introduced in the weight-selection module to enhance the energy of the residual convolution stable spectrum feature, which facilitates the accurate and subtle expression of intrinsic characteristics of the target. We evaluate our method based on frequency, phase, and amplitude in two environments with and without noise. Experimental results demonstrate that the proposed EhdNet method can achieve 94% accuracy, which is higher than the compared methods. In comparison experiments with actual data, the RMSE of EhdNet is also lower than that of other recent methods. Moreover, the proposed method outperforms ResNet, BP, and other neural network approaches in data processing across diverse working conditions due to its incorporation of a channel attention mechanism.
摘要：
The most significant driver of adaptive radiation in the New World leaf-nosed bats (Phyllostomidae) is their remarkably diverse feeding habits, yet there remains a notable scarcity of studies addressing the genetic underpinnings of dietary diversification in this family. In this study, we have assembled a new genome for a representative species of phyllostomid bat, the fringe-lipped bat (Trachops cirrhosis), and integrated it with eight published phyllostomid genomes, along with an additional 10 genomes of other bat species. Comparative genomic analysis across 10 200 orthologus genes has unveiled that those genes subject to divergent selection within the Phyllostomidae clade are notably enriched in metabolism-related pathways. Furthermore, we identified molecular signatures of divergent selection in the bitter receptor gene Tas2r1, as well as 14 genes involved in digesting key nutrients such as carbohydrates, proteins, and fats. In addition, our cell-based functional assays conducted on Tas2r1 showed a broader spectrum of perception for bitter compounds in phyllostomids compared to nonphyllostomid bats, suggesting functional diversification of bitter taste in Phyllostomidae. Together, our genomic and functional analyses lead us to propose that divergent selection of genes associated with taste, digestion and absorption, and metabolism assumes a pivotal role in steering the extreme dietary diversification in Phyllostomidae. This study not only illuminates the genetic mechanisms underlying dietary adaptations in Phyllostomidae bats but also enhances our understanding of their extraordinary adaptive radiation. Genes associated with taste, digestive system, and metabolism underlie the evolution of dietary diversification in New World leaf-nosed bats.dagger image

Abstract With the rapid expansion of agriculture on saline–alkaline soils, environmental problems such as increased greenhouse gas (GHG) emissions, eutrophication and soil degradation are becoming increasingly serious. To clarify the characteristics of carbon (C) and nitrogen (N) cycling and their loss mechanisms in cultivated saline–alkaline soils, an undisturbed soil column experiment was conducted to analyse C and N leaching and GHG emissions by applying different fertilizer rates. The experiment had six treatments using N‐(NH4)SO4 over a 40‐day seedling stage, with and without maize. Treatments were: no N with maize (0Nmaize: 0 kg N ha−1), reduced N with maize (RNmaize: 63 kg N ha−1), conventional N with maize (CNmaize: 160 kg N ha−1) and their equivalents without maize (0Nsoil: 0 kg N ha−1; RNsoil: 63 kg N ha−1; CNsoil: 160 kg N ha−1). The results indicated that reduced N with maize reduced the N2O emission by 21%, with N leaching (TN: 41%, NO3−–N: 19%, NH4+ − N: 63%) within 15 days after fertilization, but had no significant effect on CH4 emission compared to conventional N with maize. Therefore, reduced N with maize had the smallest N loss, which accounted for 1.5% of the relative percentage of N flow including N2O (0.3%), N leaching (2%), aboveground biomass N (76%) and root biomass N (22%). Compared to conventional N with maize, reduced N with maize significantly reduced N leaching by 40% because conventional N with maize greatly exceeded the crop N uptake when maize root length was only within 20 cm. Reduced N without maize reduced CO2 emission (19%) compared to conventional N without maize. Uncultivated saline–alkaline soils face greater N overuse and leaching risk because higher NO3−–N leaching (6.9 mg L−1) that occurred in bare soils without fertilization, which increased by 2.6–3.6 times when the N input increased from 63 to 160 kg N ha−1 compared to control. In conclusion, reducing conventional N fertilizer inputs by 60% is not only an effective strategy to reduce CO2 and N2O emission and N leaching but also effectively absorbs C, and the N retained in the soil tillage layer can help to meet maize seedling growth requirements in Solonchaks.

CONTEXT: Running is one of the most popular sports worldwide. However, controversies exist regarding how running affects runner's intervertebral discs (IVD). OBJECTIVE: The purpose of this study was to systematically review studies that evaluated IVD morphology or composition changes in response to running exercise, to determine the impact of running exercise on IVD. DATA SOURCES: A systematic literature search was performed for 4 major databases: PubMed, Cochrane, Embase, and Web of Science. STUDY SELECTION: Inclusion criteria were as follows: (1) healthy people without known IVD disease or major complications such as tuberculosis (IVD degeneration or low back pain are considered as minor complications); (2) subjects performed 1-time or regular running exercises; (3) pre and post comparison of runners or comparison between runners and healthy control subjects; (4) direct or indirect IVD morphology or composition measured; (5) IVD assessed before and after either acute or chronic running exercise, or compared cross-sectionally between runners and controls. Exclusion criteria were as follows: (1) reviews, editorials, letters or abstracts only; (2) animal studies; (3) subjects performed exercise other than running. STUDY DESIGN: Systematic review. LEVEL OF EVIDENCE: Level 3. DATA EXTRACTION: The extracted data included study design and primary outcomes of the included studies. The Newcastle-Ottawa scale (NOS) was used to evaluate study quality and risk of bias. RESULTS: A total of 13 studies with 632 participants were included in the final analysis; 4 studies measured IVD changes using stature or spinal height, and the other 9 measured IVD changes using magnetic resonance imaging; 6 studies found that running acutely and negatively impacts IVD; 3 out of 5 cross-sectional studies found that IVD parameters are better for runners than controls; 1 longitudinal study found no significant difference in IVD before and after training for marathon in runners; 1 longitudinal study found no significant difference in changes of IVD between runners and controls after 15 years of follow-up. CONCLUSION: Negative changes in IVD exist for a short period of time after running, which may be due to the temporary compression pushing water content out of the disc. Cross-sectional studies suggest that long-term running exerts a mild positive effect on IVD; however, this inference has not been confirmed by high-quality longitudinal studies.
摘要：
Aspect-based sentiment analysis (ABSA), which aims to analyze users’ sentiment towards the targeted aspect, has recently gained increasing attention due to its importance in supporting corresponding decision-makings in various tasks. Most existing ABSA studies primarily depend on only textual modality, but ignore the fact that in many cases the targeted aspect doesn’t appear in the sentence. Thus, multimodal ABSA is expected to alleviate this dilemma. However, most existing MABSA approaches still suffer from the following limitations: (1) ignoring the possible aspect-image irrelevant issue; (2) ignoring the coarse-grained interaction between the sentence and its associated image; (3) failing to simultaneously leverage multiple types of useful knowledge information. To address these issues, we propose an aspect-guided multi-view interactions and fusion network (AMIFN) for MABSA. Specifically, we utilize the multi-head attention mechanism to generate aspect-guided textual representation, which is used as the extended aspect semantic for guiding the subsequent aspect-related interactions. When exploring aspect-guided visual representation, we employ the image gate to dynamically filter potential noise introduced by the associated image to generate the final image representation. Meanwhile, the coarse-grained sentence-image interaction, which contains context and semantics information, and the syntactic dependencies, are leveraged for graph construction to obtain aspect-guided text-image interaction representations. Finally, the extracted multi-view interaction representations are integrated for sentiment classification. Extensive experimental results on three multimodal benchmark datasets demonstrate the superiority and rationality of AMIFN.
摘要：
Charm quark production and its hadronization in ep and eA collisions at the future Electron-ion Collider in China (EicC) will help us understand the quark/gluon fragmentation processes and the hadronization mechanisms in the nuclear medium, especially within a poorly constrained kinematic region (x < 0.1). In this paper, we report a study on the production of charmed hadrons, D-0 and Lambda(+)(c), reconstructed with a dedicated Geant4 simulation of vertex and tracking detectors designed for EicC. The Lambda(+)(c)/D-0 ratios as functions of multiplicity and p(T), as well as the D-0 double ratio are presented with projected statistical precision.

摘要：
PurposeFor a homogeneous soil, the traditional laminar flow and well-known Taylor diffusion mechanism cannot interpret dispersivity (linear relationship between dispersion coefficient and pore-water velocity). The objective of this study was to propose a new mechanism and mathematical model based on fluid mechanics.MethodsDue to the roughness of the wall of a soil capillary tube, a new turbulent flow is proposed to be eddies at the wall and laminar flow at the main stream of a soil capillary tube. A new eddy dispersion mechanism is that the behavior of solute in the eddies follows random walks and the solute mixes instantly between the wall and main stream in a tube at the microscale. The new turbulent flow and eddy dispersion occur when the pore-water velocity is greater than a critical value. Transition to the new mechanism from a laminar flow in the tube and molecular diffusion is described by a plateau-linear model. It was tested by published datasets of pore-water velocity and dispersion coefficient in miscible displacement experiments on a loam and a sandy loam.ResultsThe plateau-linear model fit the published datasets. The estimate of dispersivity was 0.135 cm. The transition of water flow and dispersion process occurred at the critical pore-water velocity 0.216 cm h-1 or Reynolds number of the order of 10-6.ConclusionDispersivity in homogeneous soils was interpretated by the turbulent water flow and the eddy dispersion mechanism.

摘要：
The Electron -Ion Collider in China (EicC) has been proposed to study the inner structure of matter and fundamental laws of strong interactions. In this paper, we will present a conceptual design of the tracking system based on the state -of -art silicon detector and micropattern gaseous detector at the EicC and demonstrate that it will enable us to reconstruct charm hadron with good significance, hence study gluonic parton distribution functions in nucleons and nuclei, as well as gluon helicity distributions. The impact study using reweighting techniques shows that the impact of the EicC will be mainly in the large x region. It complements similar physics programs at the Electron -Ion Collider at Brookhaven National Laboratory.

摘要：
Abstract Remote sensing detection of autumn phenology is challenging and highly uncertain, as exemplified by the observed divergence in autumn phenology extracted from different proxies. Here, we compared the autumn phenology derived from Solar‐Induced chlorophyll Fluorescence (SIF), Chlorophyll/Carotenoid Index (CCI), Enhanced Vegetation Index (EVI), and Normalized Difference Vegetation Index (NDVI) over deciduous forest sites. We observed a clear temporal sequence in the derived autumn phenology from various proxies: SIF < CCI < EVI < NDVI. Comparison with field measurements supported that SIF, EVI, and NDVI can successfully capture the attenuation of photosynthetic activity, leaf coloration, and leaf fall, respectively. The sequence among the autumn phenology derived from those proxies was also consistent with their responses to climate cues, where SIF had the highest partial correlation coefficient to solar radiation in autumn, followed by CCI, EVI, and NDVI, while NDVI was more correlated with temperature, followed by EVI, CCI, and SIF.
摘要：
CsPbBr(3) has received more and more attention in the field of optoelectronic devices due to its excellent stability. To address the cost and environmental concerns associated with the use of toxic methanol, water has been explored as a substitute solvent for CsBr in the preparation of CsPbBr(3) perovskite solar cells (PSCs). In this study, we utilized methanol as an anti-solvent of the CsBr/H(2)O solution to regulate the detrimental effects of water on the CsPbBr(3) film and control the crystallization process. From results of the experiment, it was found that methanol anti-solvent treatment greatly improved the crystallization of the CsPbBr(3) film, increased the grain size, and reduced the defect density. After the introduction of methanol anti-solvent treatment, the power conversion efficiency (PCE) increased from 6.09% to 7.91%, while the open-circuit voltage (V(oc)) increased from 1.18 V to 1.39 V. Furthermore, we incorporated 2-hydroxyethylurea into the CsPbBr(3) PSCs to improve the wettability of PbBr(2) towards the CsBr/H(2)O solution and ensure the formation of pure-phase CsPbBr(3) films. The introduction of 2-hydroxyethylurea resulted in an additional increase in V(oc) from 1.19 V to 1.42 V. The PCE further improved from 6.56% to 8.62% after methanol anti-solvent treatment. These results demonstrate that methanol treatment effectively addresses the low V(oc) issue observed in CsPbBr(3) PSCs prepared with water as a solvent. Importantly, this approach significantly reduces the reliance on methanol compared to conventional fabrication methods for CsPbBr(3) PSCs. Overall, this work presents a promising pathway for achieving high V(oc) and efficiency in CsPbBr(3) PSCs by utilizing water as a solvent.

摘要：
Floods are some of the most frequent and severe natural hazards worldwide. In the context of climate change, the risk of extreme floods is expected to increase in the future. While, the trends in flood timing and risk for flood synchronization remain unclear. In this study, the seasonality of flood peaks, annual maximum rainfall, and annual maximum soil moisture in the Yangtze River Basin were examined using observational and reanalysis data from 1949 to 2020. Changes in the timing of extreme events may increase the possibility of concurrent flooding, therefore the risk for synchronous floods were further explored. The results indicate that the seasonality of floods has a strong consistency with that of annual maximum rainfall. In the southern Yangtze River Basin, floods usually occur between early June and early July, with a delayed trend. However, they occur slightly later in the north, generally from late July to early August, with a tendency of advance. Overall, the timing of floods is positively correlated with rainfall and soil moisture peaks, and the correlation is much stronger for annual maximum rainfall. However, for more intense floods or for larger catchments, soil moisture plays an important role in modulating the variations in flood timing. Reverse latitudinal changes in flood timing are expected to result in more synchronous floods. The synchrony frequency exceeded 60 % for most of the stations, and the frequency was increasing for nearly half of the region, especially in the middle reaches, Poyang Lake and south of Dongting Lake. In addition, the flood synchrony scale in the south of the basin showed significant upward trends. These findings would provide important implications for flood risk management and adaptive strategy development.
摘要：
Although snow cover is a major factor affecting vegetation in alpine regions, it is rarely introduced into ecological niche models in alpine regions. Snow phenology over the Tibetan Plateau (TP) was estimated using a daily passive microwave snow depth dataset, and future datasets of snow depth and snow phenology were projected based on their sensitivity to temperature and precipitation. Furthermore, the potential habitats of five alpine vegetation types on the TP were predicted under two future climate scenarios (SSP245 and SSP585) by using a model with incorporated snow variables, and the driving factors of habitat change were analyzed. The results showed that the inclusion of snow variables improved the prediction accuracy of MaxEnt model, particularly in alpine meadow habitats. By the end of the 21st century, the potential habitats of steppes, meadows, shrubs, deserts, and coniferous forests on the TP will migrate to higher latitudes and altitudes, in which the potential habitats of alpine desert will recede (replaced by alpine steppe), and the potential habitats of other four vegetation types will expand. The random forest importance analysis showed that the recession of potential habitat was mainly driven by the increase in average annual temperature, and the expansion of potential habitat was mainly driven by the increase in precipitation. With the gradual increase in temperature and precipitation in the future, the snow depth and snow cover duration days will decrease, which may further lead to the transition of vegetation types from cold-adapted to warm-adapted on the TP. Our study highlights both that the prediction accuracy of alpine vegetation was improved by incorporating snow variables into the species distribution model, and that a changing climate will likely have a powerful influence on the distribution of alpine vegetation across the TP.
摘要：
This paper features a study of statistical inference for linear inverse problems with Gaussian noise and priors in structured Banach spaces. Employing the tools of sectorial operators and Gaussian measures on Banach spaces, we overcome the theoretical difficulty of lacking the bias-variance decomposition in Banach spaces, characterize the posterior distribution of solution though its Radon-Nikodym derivative, and derive the optimal convergence rates of the corresponding square posterior contraction and the mean integrated square error. Our theoretical findings are applied to two scenarios, specifically a Volterra integral equation and an inverse source problem governed by an elliptic partial differential equation. Our investigation demonstrates the superiority of our approach over classical results. Notably, our method achieves same order of convergence rates for solutions with reduced smoothness even in a Hilbert setting.

摘要：
Online teaching is considered an important approach for achieving sustainable learning and education, and college teachers’ attitude and behavioral intention are essential for the sustainable adoption of online teaching practice in higher education institutions. To examine the influencing factors that sustain teachers’ attitude toward online teaching and behavioral intention, we conducted a cross-sectional study based on a sample of 1102 college teachers in Central China using hierarchical linear regression analysis to explore the possible influencing factors at the following four levels: individual experience, environmental support, self-perception, and technology acceptance. The study results show that the subjective norms, readiness, beliefs, and perceived usefulness of online teaching had a significant impact on the teachers’ attitude toward online teaching and behavioral intention. Nevertheless, the effect varied with factors like the online teaching load and teachers’ technology self-efficacy, and their influence seemed to be singular, affecting the teachers’ attitude toward online teaching or behavioral intention exclusively. In contrast, previous online teaching experience did not notably affect either. The findings of this study reveal the complex interactions of the factors that influence college teachers’ disposition toward and decisions about online teaching practices and emphasize the need for targeted strategies to maintain and enhance online education in the post-pandemic era.
