摘要：
During field work on mutualisms between oil bees and Cucurbitaceae in Yunnan, China, we discovered a new species of Thladiantha that we here describe and illustrate. It is overall similar to T. globicarpa A.M.Lu & Zhi Y.Zhang from Guangxi, but differs in the shape of its fruits. DNA sequences of the new species analyzed in the context of a densely sampled phylogeny of Thladiantha confirm its distinctness from all other species. The molecular data also revealed another collection of the new species made in Guangxi in 1937. Like all Thladiantha, the new species offers oil in glandular hairs on its petals and is pollinated by oil -collecting Ctenoplectra bees.

摘要：
Insect resistance evolution poses a significant threat to the advantages of biopesticides and transgenic crops utilizing insecticidal Cry-toxins from Bacillus thuringiensis (Bt). However, there is limited research on the relationship between transcriptional regulation of specific toxin receptors in lepidopteran insects and their resistance to Bt toxins. Here, we report the positive regulatory role of the SfGATAe transcription factor on the expression of the ABCC2 gene in Spodoptera frugiperda. DNA regions in the SfABCC2 promoter that are vital for regulation by SfGATAe, utilizing DAP-seq technology and promoter deletion mapping. Through yeast one-hybrid assays, DNA pull-down experiments, and site-directed mutagenesis, we confirmed that the transcription factor SfGATAe regulates the core control site PBS2 in the ABCC2 target gene. Tissue-specific expression analysis has revealed that SfGATAe is involved in the regulation and expression of midgut cells in the fall armyworm. Silencing SfGATAe in fall armyworm larvae resulted in reduced expression of SfABCC2 and decreased sensitivity to Cry1Ac toxin. Overall, this study elucidated the regulatory mechanism of the transcription factor SfGATAe on the expression of the toxin receptor gene SfABCC2 and this transcriptional control mechanism impacts the resistance of the fall armyworm to Bt toxins.
摘要：
Accurate wind speed forecasting is capable of increasing the stability of wind power system. Notably, there are numerous factors affecting wind speed, thus causing wind speed forecasting to be difficult. To address the above -mentioned challenge, a novel hybrid model integrating genetic algorithm (GA), variational mode decomposition (VMD), improved dung beetle optimization algorithm (IDBO), and Bidirectional long short-term memory network based on attention mechanism (BiLSTM-A) is proposed in this study to achieve satisfactory forecasting performance. In the proposed model, GA is adopted to optimize the VMD to eliminate noise and extract original series attributes. And the IDBO is adopted for hyperparameters selection for the BiLSTM-A. The proposed GA-VMD-IDBO-BiLSTM-A is compared with nine established comparable models, with the aim of verifying its forecasting performance. A series of experiments on four 1 -hour real wind series in Stratford are performed to assess the performance of the model. The MAPE of the four datasets forecasting results reached 1.4%, 2.4%, 3.5%, 2.4%. As indicated by the experimental results, GA-VMD can better process the data and improve the forecasting accuracy. IDBO can optimize the parameters of BiLSTM model and improve the forecasting performance. The dual -optimization wind speed forecasting model can obtain high accuracy and strong stability.

摘要：
ObjectivesMindful self-care is a way of embodied self-regulation that can safeguard and enhance psychological well-being. This study aimed to test the reliability and validity of the Chinese version of the Mindful Self-Care Scale (MSCS) among college students.MethodA total of 1486 college students (Mage = 19.36, SD = 1.16) from four different universities participated in this study. All participants completed a series of online surveys, including the MSCS, the Self-Compassion Scale-Short Form, the Body Appreciation Scale-2, and the Satisfaction With Life Scale. Confirmatory factor analysis was used to evaluate the validity of the MSCS, and the R package measureQ was utilized to calculate the reliability. Additionally, we conducted comparative analyses involving the MSCS (33 items), its brief version (Brief-MSCS, 24 items), and previous relevant research.ResultsThe MSCS and Brief-MSCS demonstrated an acceptable factor structure, while the Brief-MSCS exhibited a more robust structure. Notably, the bifactor model adequately fitted the data for both versions. In bifactor model, each item not only belonged to its own group of factors but also belonged to a general factor. Both versions displayed satisfactory convergent validity, discriminant validity, concurrent validity, and robust composite reliability. Furthermore, Chinese college students exhibited a higher level of mindful self-care than Chinese medical professionals and a Western community sample.ConclusionsThe MSCS and Brief-MSCS have been found to be reliable and valid tools for assessing the levels of mindful self-care among college students, with the brief version showing superior performance. The robust fit of the bifactor model suggests that there is an overarching structure of mindful self-care that can be used to assess an individual's level through the total score. Moreover, there are differences in the level of mindful self-care among different groups, which need further verification.PreregistrationThis study is not preregistered.
摘要：
The random and fluctuating nature of wind energy brings tremendous challenges and disturbances to the security operation of wind power systems, accurate wind power prediction can effectively reduce these negative impacts. To this end, this paper proposes a hybrid wind power prediction model based on the "decomposition-reconstruction-ensemble" strategy, which consists of four main components, namely decomposition, reconstruction, prediction, and ensemble. Specifically, the original wind power series is decomposed into several sub-modes and reconstructed by frequency by the sample entropy(SE)-optimized variational modal decomposition(VMD) algorithm, subsequently, the Pearson correlation coefficients between the wind speed time series and the reconstructed components of wind power are calculated to divide the wind power series into trend and fluctuation components. Then both the two components are sequentially predicted using the temporal convolutional network(TCN) model. The final predicted value is obtained from the set of predicted results for each component. The wind power data from two wind farms in Hami, Xinjiang are adopted as examples for empirical study, and the results show that the IVMD-R-TCN model proposed in this paper performs significantly better than the benchmark model, which illustrates the predictive validity of the proposed model and is an effective tool for wind power forecasting.

摘要：
Exploring carbon emission effects based on the evolution of residents’ dietary structure to achieve the carbon neutrality goal and mitigate climate change is an important task. This study took China as the research object (data excluding Hong Kong, Macao and Taiwan) and used the carbon emission coefficient method to quantitatively measure the food carbon emissions from 1987–2020, then analyzed the carbon emission effects under the evolution of dietary structure. The results showed that during the study period, the Chinese dietary structure gradually changed to a high-carbon consumption pattern. The dietary structure of urban residents developed to a balanced one, while that of rural residents developed to a high-quality one. During the study period, the per capita food carbon emissions and total food consumption of Chinese showed an increasing trend. The per capita food carbon emissions of residents in urban and rural showed an overall upward trend. The total food carbon emissions in urban increased significantly, while that in rural increased first and then decreased. The influence of beef and mutton on carbon emissions is the highest in dietary structure. Compared with the balanced dietary pattern, the food carbon emissions of Chinese residents had not yet reached the peak, but were evolving to a high-carbon consumption pattern.

摘要：
As a result of rapid urbanization in China, the spatial restructuring of towns and cities has significantly impacted urban compactness. The study of the spatio–temporal characteristics and driving mechanisms of urban compactness in central China is a strategic imperative and conducive to promoting regional sustainable development that is based on easing the contradiction between land resource supply and demand and reducing energy consumption. Therefore, this study focused on 80 prefecture-level cities in central China, utilizing barycenter model and GTWR model, among others, to analyze the spatio–temporal evolution pattern of urban compactness from 2006 to 2020 and its driving factors, with the aim of uncovering the intrinsic mechanisms behind enhancing urban compactness in the area. The results show the follows: (1) The urban compactness in central China has generally shown an upward trend, with a pronounced spatial clustering around provincial capital cities and the spatial changes in compactness predominantly concentrated in the north–south direction. (2) Various factors have influenced urban compactness, where government intervention and population aggregation present as bi-directional driving factors, while the effective use of land resources and high-quality industrial development, among others, present as positive driving factors. The spatio–temporal heterogeneity and agglomeration features of each driving factor are significant. (3) Further analysis indicates that the effective use of land resources is the primary factor in enhancing urban compactness, followed by technology. Therefore, we should adhere to the concept of compact cities and gradually promote the compactness of cities in central China based on the impact of the driving factors.
摘要：
Upland cotton, the mainly cultivated cotton species in the world, provides over 90% of natural raw materials (fibers) for the textile industry. The development of cotton fibers that are unicellular and highly elongated trichomes on seeds is a delicate and complex process. However, the regulatory mechanism of fiber development is still largely unclear in detail. In this study, we report that a homeodomain-leucine zipper (HD-ZIP) IV transcription factor, GhHOX4, plays an important role in fiber elongation. Overexpression of GhHOX4 in cotton resulted in longer fibers, while GhHOX4-silenced transgenic cotton displayed a "shorter fiber" phenotype compared with wild type. GhHOX4 directly activates two target genes, GhEXLB1D and GhXTH2D, for promoting fiber elongation. On the other hand, phosphatidic acid (PA), which is associated with cell signaling and metabolism, interacts with GhHOX4 to hinder fiber elongation. The basic amino acids KR-R-R in START domain of GhHOX4 protein are essential for its binding to PA that could alter the nuclear localization of GhHOX4 protein, thereby suppressing the transcriptional regulation of GhHOX4 to downstream genes in the transition from fiber elongation to secondary cell wall (SCW) thickening during fiber development. Thus, our data revealed that GhHOX4 positively regulates fiber elongation, while PA may function in the phase transition from fiber elongation to SCW formation by negatively modulating GhHOX4 in cotton.

摘要：
Consider time-harmonic electromagnetic wave scattering by an infinitely long, cylindrical, orthotropic dielectric partially coated with a very thin layer of a highly conductive material, which can be modeled by a transmission problem with mixed boundary conditions. Having established the well-posedness of the direct and interior transmission problem by the variational method under certain conditions, we make use of the classical linear sampling method to reconstruct the shape of the obstacle. Then, based on a modification of the general data-to-pattern operator G, we propose a novel and simple method to justify the modified linear sampling method.

摘要：
This paper addresses the meromorphic continuation of the outgoing resolvent associated with Schro"\dinger-type operators in three dimensions. The first part focuses on the classical Schro"\dinger-type operator involving unbounded potentials. The absence of nonzero real poles for the outgoing resolvent is investigated. The second part examines the fractional Schro"\dinger operator, including both bounded and unbounded potentials. The analysis relies on a resolvent identity that establishes a connection between the resolvents of the fractional Schro"\dinger operator and its classical counterpart.
摘要：
Linear complementary dual (LCD) codes can provide an optimum linear coding solution for the two-user binary adder channel. LCD codes also can be used to against side-channel attacks and fault non-invasive attacks. Let dLCD(n,k) denote the maximum value of d for which a binary [n,k,d] LCD code exists. In \cite{BS21}, Bouyuklieva conjectured that dLCD(n+1,k)=dLCD(n,k) or dLCD(n,k)+1 for any lenth n and dimension k >= 2. In this paper, we first prove Bouyuklieva's conjecture \cite{BS21} by constructing a binary [n,k,d-1] LCD codes from a binary [n+1,k,d] LCDo,e code, when d >= 3 and k >= 2. Then we provide a distance lower bound for binary LCD codes by expanded codes, and use this bound and some methods such as puncturing, shortening, expanding and extension, we construct some new binary LCD codes. Finally, we improve some previously known values of d(LCD)(n,k) of lengths 38 <= n <= 40 and dimensions 9 <= k <= 15. We also obtain some values of d(LCD)(n,k) with 41 <= n <= 50 and 6 <= k <= n-6.
摘要：
We study a new family of metrics, weighted poset block metric, which generalizes the weighted coordinates poset metric introduced by Panek and Pinheiro (IEEE Trans Inf Theory 66(11):6823–6834, 2020) and the metric for linear error-block codes introduced by Feng et al. (Finite Fields Appl 12(4):638–652, 2006). This metric covers various metrics such as Hamming metric, Lee metric, poset metric, pomset metric, poset block metric, pomset block metric and so on. We give a complete description of the groups of linear isometries of these metric spaces in terms of a semi-direct product. Moreover, we obtain a Singleton type bound for codes equipped with weighted poset block metric and define MDS codes. When the poset is a chain, we study the relationship between MDS codes and perfect codes.
摘要：
Logistics services are integral to urban economic activity, and delving into the spatial distribution traits and evolutionary pathways of various kinds of logistics service node facilities (LSNF) is markedly valuable for understanding a city’s functional spatial makeup and refining the spatial layout of logistics services. This study quantitatively and qualitatively analyzes the spatial congregation and spreading characteristics of diverse LSNFs in Wuhan in 2011, 2014, 2017, and 2020, employing kernel density analysis, average nearest neighbor index, mean center, and distance distribution frequency, seeking to characterize the spatial evolution characteristics of LSNF, alongside examining the trends in distances to city cores, principal adjoining roads, and production and consumption sites. The following conclusions were made: (1) Between 2011 and 2020, various types of LSNFs in Wuhan experienced a pattern characterized by the noticeable coexistence of spatial expansion and agglomeration, particularly visible after 2014. The degree of agglomeration is classified in a descending order as follows: CWC, STN, PSN, and PDN. (2) An “absolute diffusion” phenomenon characterizes the distribution of distances between various kinds of LSNFs and city cores or neighboring roads, with the lion’s share of high-frequency distribution zones spreading beyond city cores by 5–10 km, and a majority of the LSNFs being situated within 1 km from adjacent roads. (3) While the LSNF collective exhibits a stronger tendency towards the consumption facet, it reflects a surrounding of industrial production sites on the production facet and locations of manufactured goods consumption on the consumption facet, followed by locations of agricultural product consumption and comprehensive consumption sites.
