在当今科技革命和产业变革方兴未艾的时代背景下,知识和技术成为经济增长和财富积累的主要驱动力,企业家等高能力人力资本作为知识和技术的载体,在企业的经营决策和创新创造中占据主导地位。同时,企业家人力资本的稀缺性和专用性及其风险承担能力和创造能力的提升使得企业家人力资本相对价格提高,财务资本相对价格降低,从而促使公司治理范式从“资本雇佣劳动”向“劳动雇佣资本”变革。高科技时代背景、资本市场完善导致的股权多元化以及企业较高的创新发展需求为“劳动雇佣资本”治理范式发展提供了适用环境。此外,“劳动雇佣资本”治理范式不仅会极大地激发企业家能力,也会引发企业各治理主体权益发生变化,进而能够通过提高治理效率和实现制度革新推动新质生产力的发展。

目的探究轻度创伤性颅脑损伤患者脑结构网络的改变与未来睡眠障碍的关联。方法前瞻性搜集轻度创伤性颅脑损伤患者198例(mTBI组)及与之匹配的健康对照者60名(HC组)。以出院3个月后的匹兹堡睡眠质量指数量表(PSQI)为评估手段,将轻度创伤性颅脑损伤患者分为睡眠障碍组(mTBI-SD组)和无睡眠障碍组(mTBI-ND组)。利用方差分析比较3组受试者脑结构网络属性。构建Logistic回归模型探究脑结构网络属性与未来睡眠障碍发病风险的关联。采用Pearson相关分析探究脑结构网络属性与PSQI评分的相关性。结果3组受试者脑结构网络属性存在显著的组间差异。与mTBI-ND组相比,mTBI-SD组表现出较高的特征路径长度,较低的左前扣带回和旁扣带回节点效率。Logistic回归模型显示特征路径长度(OR特征路径长度=0.74,95%CI:0.63~0.94,P<0.001)、左前扣带和旁扣带回的节点效率(OR ACG.L=0.70,95%CI:0.65~0.80,P<0.001)可以显著预测mTBI-SD的发生,受试者工作特征曲线下面积分别为0.75、0.74。相关分析结果显示mTBI-SD组的特征路径长度(r=-0.41,P<0.01)、左前扣带和旁扣带回的节点效率(r=-0.50,P<0.01)与发病后3个月的PSQI评分相关。结论mTBI显著改变患者的脑结构网络连接属性,存在特征路径长度、左前扣带回和旁扣带回的节点效率改变的患者更容易在未来发生睡眠障碍。

In this study, we evaluate the effect on ion-trap quantum computers（QCs） from the quantum nature of the driving field, and propose a theoretical limit for ion-trap QCs that may impact the design of quantum algorithms and realization of practical QCs. We obtain, for the first time, the permitted depth of logical operation for fault-tolerant ion-trap QCs. Physically, we provide an exact（full-quantum） description of the QC system, and present for the first time its time evolution after gate operations; mathematically,we solve problems such as certain summations of trigonometric series with any given precision. Comparing the actual state after CNOT gates driven by a quantized field with the expected state, we obtain the failure probability and estimate that the number of CNOT gates on the same pair of physical qubits is not more than 10;in one error-correction period, which is a physical limit that cannot be easily overcome. The conclusion can help determine the number of CNOT operations between coding and decoding in one error-correction period and can be used as a reference for quantum algorithm design.

In tensor theory, the parallel factorization （PARAFAC）decomposition expresses a tensor as the sum of a set of rank-1tensors. By carrying out this numerical decomposition, mixedsources can be separated or unknown system parameters can beidentified, which is the so-called blind source separation or blindidentification. In this paper we propose a numerical PARAFACdecomposition algorithm. Compared to traditional algorithms, wespeed up the decomposition in several aspects, i.e., search di-rection by extrapolation, suboptimal step size by Gauss-Newtonapproximation, and linear search by n steps. The algorithm is ap-plied to polarization sensitive array parameter estimation to showits usefulness. Simulations verify the correctness and performanceof the proposed numerical techniques.
