在机器中复制人类意识(可被理解为一种直接的第一人称主观体验)的想法是这个时代最大的挑战之一.对现象意识的本质的科学理解可能需要扩展科学方法本身.可以暂时搁置解决该问题,而先尝试在功能主义的框架内在计算机中重现意识现象.迄今为止,为此所提出的相关理论似还存在问题.提出了一种基于BICA(生物启发认知架构)结合LLM(大语言模型)实现类人意识的方法,并以虚拟导师为案例对其进行说明.一般认为,上述问题的最终解决方案可以以纯神经形态的形式获得,且这一形式能使其得以进一步变更、发展和演化.为此,从意识的本体论问题及其暂时的非还原解决方案开始讨论,因为这是科学研究的一条可行路线.主要假设是基于“BICA挑战”中有关eBICA认知架构制定的,作为例子仅分析了有限的社会情感意识案例,解释了本身不具备意识的LLM如何通过ChatGPT连接到eBICA,用于构建有意识的人工制品原型并验证其声称的性能.所选定的虚拟导师案例进一步说明了这项技术将如何使虚拟导师发展出人类级别的师生关系,从而提高辅导效率.未来的研究方向可以包括创建各种各样具有感知能力、且有可能进一步自主进化的代理物,以满足人类的众多实际需求.

In this paper, the application of homotopy methods to the load flow multi-solution problems of power systems is introduced. By the generalized Bernshtein theorem, the combinatorial number C2n^m is shown to be the BKK bound of the number of isolated solutions of the polynomial system transformed from load flow equations with generically chosen coefficients. As a result of the general Bezout number, the number of paths being followed is reduced significantly in the practical load flow computation. Finally, the complete P-v cures are obtained by tracking the load flow with homotopy methods.

An experiment was designed to determine the influence of fibre and betaine on the development of the intestine, liver and pancreas of broilers from hatch to 14 d of age. A total of 250-day-old Cobb 500 male broilers were allocated to 16 cages with 15 broilers each. Treatments were arranged in a 2 x 4 factorial design, consisting of 2 feed formulations(low and high fibre diets) and 4 levels of betaine(0,1, 3 or 5 kg/t). At hatch, 10 birds in total were euthanised, and samples of the liver, pancreas, yolk sac and intestine were collected for reference of the analysed parameters before the start of the *** d 4.9 and 14, 5 birds per cage(10 birds per treatment) were selected, euthanised and treated as the same as the birds at hatch. villus height and width and crypt depth were determined on the duodenum samples, and absorptive area was calculated. The number of enterocytes in mitosis at the villus was determined by a positive reaction to antibody for Ki67 protein, and fused villus was evaluated visually. The relative weight of the yolk sac reduced(P ver reached a maximum(P ve weight of the pancreas and higher villus(P villus width increased(P iated with fused villus.

The higher fibre diet increased feed intake and villus height, yet reduced pancreas relative weight, while not affecting body weight gain. This response was possibly due to a dilution effect of the fibre, reducing nutrient absorption

Employing deep learning for pavement crack detection can significantly enhance accuracy， and federated learning can help to overcome the challenges of data silos and data security. This paper proposes a lightweight method to detect cracks. We use lightweight encoder modules to extract multi-scale features， and further feature fusion and modelling by Selective Fusion Blocks and Irregular-aware Blocks. Moreover， this method is the first to combine federated learning with crack detection， effectively resolving the tension between data privacy and data sharing in decentralised devices. Experiments were conducted to compare our proposed method with other crack detection methods on two publicly available datasets， including the original method without federated learning and five state-of-the-art methods combined with the same federated learning framework. The experiment proves that our model obtains comparable F1 score with minimal parameters and computational effort. For example， compared to the original method， the number of parameters and computation are reduced by 67.1% and 73.6%， respectively.

高速化成为当前R290压缩机发展的一个重要趋势。在满足R290压缩机高速运行时高可靠性的前提下,提升其性能成为重要的研究方向。建立了包含高转速R290旋转压缩机吸气-压缩-排气过程在内的三维流固耦合(3D-FSI)模型,并通过p-v实验验证了仿真的可靠性。基于仿真结果,发现并解释了对称双排气结构在压缩机排气阶段中存在的上下气阀非对称运动现象。为进一步提升旋转压缩机在高速运行时的性能,设计了4种双排气结构并通过3D-FSI仿真计算了所对应的压缩机工作腔内物理量的变化过程,绘制出了各自的p-v图。同时对气阀的动态特性进行了分析,并根据容积效率、指示效率、COP以及气阀等效应力等指标给出了较优方案。
