进入数字化时代,领导力的内涵发生了巨大改变,数字思维能力、数字技术能力、数字空间能力等构成了数字领导力新的结构。元宇宙推动数字生产力向前发展的同时,又会给数字领导力带来一定改变。这种改变带来了正反两方面的影响,从风险来看:首先,受资本逻辑影响,算法的霸权可能导致人们成为“数据人”;其次,数字领导力和现实世界的领导力之间存在潜在“二元对冲”的风险;此外,在数字安全的背景下,人们可能被异化为“技术工具”。从赋能来看:元宇宙为数字领导力提供了理念、空间、技术方面的赋能,有助于推动数字领导力全方位迭代升级,使其更好地适应数字时代的要求。

热连轧板坯温度的连续、实时预报是提高带钢产品性能的关键,针对热连轧过程数据维度过高不利于快速、准确预测板坯温度的问题,提出一种基于随机森林-长短期记忆神经网络(RF-LSTM)的板坯粗轧出口温度预测模型。首先,采用改进随机森林算法对特征变量进行选择,通过分析板坯粗轧出口温度的预测结果变化衡量特征的贡献度,进而构造反映过程数据特征与板坯温度的特征选择评价函数;其次,针对热连轧过程数据具有时间序列特性的特点,采用LSTM预测板坯粗轧出口温度;通过钢厂实际的热连轧过程数据特征选择实验验证和对比分析,结果表明:特征选择前后钢坯的温度预测平均绝对误差、均方根误差分别下降了0.21、0.25℃,预测相对误差在±3.0%以内的精度达到了99.07%。

Gene Ontology(GO)has been widely used to annotate functions of genes and gene products.Here,we proposed a new method,Triplet GO,to deduce GO terms of protein-coding and noncoding genes,through the integration of four complementary pipelines built on transcript expression profile,genetic sequence alignment,protein sequence alignment,and naīve probability.Triplet GO was tested on a large set of 5754 genes from 8 species(human,mouse,Arabidopsis,rat,fly,budding yeast,fission yeast,and nematoda)and 2433 proteins with available expression data from the third Critical Assessment of Protein Function Annotation challenge(CAFA3).Experimental results show that Triplet GO achieves function annotation accuracy significantly beyond the current state-of-the-art approaches.Detailed analyses show that the major advantage of Triplet GO lies in the coupling of a new triplet network-based profiling method with the feature space mapping technique,which can accurately recognize function patterns from transcript expression profiles.Meanwhile,the combination of multiple complementary models,especially those from transcript expression and protein-level alignments,improves the coverage and accuracy of the final GO annotation results.The standalone package and an online server of Triplet GO are freely available at https://***/Triplet GO/.

Aim: The effect of a renewed SS-cream (RSSC) on the treatment of premature ejaculation (PE) was evaluated and compared with the original SS-cream (OSSC). Methods: Sixty male white New Zealand rabbits, weighing 2.5kg-3.0 kg, were divided at random into 3 groups: the RSSC, OSSC and placebo groups. The spinal somatosensory evoked potential (SSEP) elicited by electric stimulation of the glans penis with disk electrode was investigated with an electrophysiograph (Poseidomn, Shanghai, China) before and 10, 30 and 60 min after drug or placebo application on the glans. The Onset and the N1 latencies and the amplitude of SSEP were recorded and analyzed. Results: There was no significant difference (P>0.05) in the mean Onset and Nl latency of SSEP among the 3 groups before drug application. Compared with the pre-application value, the mean Onset and Nl latencies in the RSSC and OSSC groups were significantly prolonged at 10, 30 and 60 min after treatment (P0.05) in the placebo group. The mean Onset latency of RSSC at 10 and 30 min and that of OSSC at 30 min were significantly delayed (P<0.05) compared with the placebo group. The mean Nl latency of RSSC at 30 and 60 min and that of OSSC group at 30 min were also significantly delayed (P<0.05). Conclusion: RSSC delays the latencies of SSEP, suggesting a local desensitizing effect on the sensory receptor of the glans penis dorsal nerve, which provides the potential for PE treatment. The desensitizing effect of RSSC is higher than that of OSSC.

Aim: To assess the psychometric properties of the Chinese Index of Premature Ejaculation (CIPE). Methods: The sexual function of 167 patients with and 114 normai controls without premature ejaculation (PE) were evaluated with CIPE. All subjects were married and had regular sexual activity. The CIPE has 10 questions, focusing on libido, erectile function, ejaculatory latency, sexual satisfaction and difficulty in delaying ejaculation, self-confi dence and depression. Each question was responded to on a 5 point Likert-type scale. The individual question score and the total scale score were analyzed between the two groups. Results: There were no significant differences between the age, duration of marriage and educational level (P > 0.05) of patients with and vvithout PE and normai controls. The mean latency of patients with PE and normai controls were 1.6±1.2 and 10.2±9.5 minutes, respectively. Significant differences between patients with (26.7±4.6) PE and normai controls (41.9±4.0) were observed on the total score of CIPE (P ying ejaculation, anxiety and depression. Receiver Operat ing Characteristic (ROC) curve analysis of CIPE-5 questionnaire indicated that the sensitivity and specificity of CIPE were 97.60 % and 94.74 %, respectively. Employing the total score of CIPE-5, patients with PE could be divided into three groups: mild (>15 point) 19.8 %, moderate (10-14 point) 62.8 % and severe (ying the efficacy of pharmacologica] intervention.

Ecological civilization construction is a new concept and trend in the era of China's high-quality development.It requires the collaborative propulsion of an ecological economic civilization,ecological social civilization,and ecological environment civilization.Reducing carbon emission intensity is an important issue facing the Chinese government in the backdrop of global warming.Thus,studying the influence of ecological civilization construction on carbon emission intensity from different perspectives has important theoretical and practical significance.In this study,the influences of the three subsystems of an ecological civilization on carbon emission intensity are empirically analyzed using Chinese provincial panel data from 2004 to 2016 and a spatial Durbin model based on the STIRPAT model.First,the Moran's I of carbon emission intensity in Chinese provinces was between 0.425 and 0.473.This indicates positive spatial correlation and illustrates that the carbon emission intensity of China's provinces can influence each other.The reasons behind this correlation include close ties between neighboring provinces and similarities in natural,economic,and social characteristics.Second,the correlation coefficients of ecological economic civilization,ecological social civilization,and ecological environment civilization to carbon emission intensity are−4.743139,2.865884,and−0.3246447,respectively.This illustrates that an ecological economic civilization and ecological environment civilization can reduce carbon emission intensity,while an ecological social civilization can increase it.To reduce total carbon emission intensity,the three subsystems of ecological civilization should have a negative relationship with carbon emission intensity,so the effect of ecological social civilization on carbon emission intensity should be changed.Third,the spatial spillover effect of ecological social civilization did not pass the significance test.The correlation coefficients of spatial spillover effect to ecological economic civili
