Distinct from human cognitive processing, deep neural networks trained by backpropagation can be easily fooled by adversarial examples. To design a semantically meaningful representation learning, we discard backpropagation, and instead, propose a local contrastive learning, where the representations for the inputs bearing the same label shrink(akin to boson) in hidden layers,while those of different labels repel(akin to fermion). This layer-wise learning is local in nature, being biologically plausible.A statistical mechanics analysis shows that the target fermion-pair-distance is a key parameter. Moreover, the application of this local contrastive learning to MNIST benchmark dataset demonstrates that the adversarial vulnerability of standard perceptron can be greatly mitigated by tuning the target distance, i.e., controlling the geometric separation of prototype manifolds.

Spatial memory is crucial for survival within external surroundings and wild *** hippocampus,a critical hub for spatial learning and memory formation,has received extensive investigations on how neuromodulators shape its functions(Teixeira et al.,2018;Zhang et al.,2024).However,the landscape of neuromodulations in the hippocampal system remains poorly understood because most studies focus on classical monoamine neuromodulators,such as acetylcholine,serotonin,dopamine,and *** neuropeptides,comprising the most abundant neuromodulators in the central nervous system,play a pivotal role in neural information processing in the hippocampal ***(CCK),one of the most abundant neuropeptides,has been implicated in regulating various physiological and neurobiological statuses(Chen et al.,2019).CCK-A receptor(CCK-AR)and CCK-B receptors(CCK-BR)are two key receptors mediating the biological functions of CCK,both of which belong to class-A sevenfold transmembrane G protein-coupled receptors(Nishimura et al.,2015).CCK-AR preferentially reacts to sulfated CCK,whereas CCK-BR binds both CCK and gastrin with similar affinities(Ding et al.,2022).The expression patterns of CCK-AR and CCK-BR are distinct,implying that CCK has various functions in target *** instance,CCK-AR is widely expressed in the GI and brain subregions and is hence implicated in the control of digestive function and satiety ***,CCK-BR is abundantly and widely distributed in the central nervous system,which majorly regulates anxiety,learning,and memory(Ding et al.,2022).However,the roles of endogenous CCK and CCK receptors in regulating hippocampal function at electrophysiological and behavioral levels have received less attention.

考虑运行平稳性的成品油管道调度方法

成品油管道调度计划是管道完成输送任务的重要运行依据,除了要保障按时、按量地将油品输送到沿线站场外,还应尽量维持管道的平稳运行,提高管道调度整体服务质量。目前,对于采用集中分输工艺的成品油管道,已有国内外调度计划制定研究尚无法将管道运行平稳性因素纳入考虑范围。而且,部分文献证实,若仅以水力约束的方式控制管道流量,会引起管段流量在某一范围内波动频繁的问题,进而会削弱管道运行安全性,致使研究成果脱离工程实际,鲜有落地应用。本文针对单源多汇的成品油管道,在现有研究的基础上,引入了流量波动系数、操作次数上限等适应于集中分输工艺的关键参数,并基于离散时间表达方法提出优化策略。此后,对站场分输工艺、管段运行流量、批次跟踪、预估下载量、下载偏差以及流量偏差等约束进行考虑,并以下载偏差和运行流量波动最小为目标函数,结合现场在相邻站场操作时间节点上改变本站下载流量的人工编制计划经验,构建了管道调度计划自动编制模型,实现了考虑运行平稳性的成品油管道调度计划的快速制定。所建模型应用于我国包含9座站场的某实际成品油管道,在2分钟内能够准确求解出该管道月调度计划;调度计划充分考虑了该管道全分输工艺、一次性下载要求,满足通用性要求;求解结果在运行过程中的正常流量波动占比90%,油品需求偏差控制在-3.23%~3.65%以内,具有较强的工程实用性。本研究成果对于采取集中分输工艺的成品油管道运行企业,在制定调度计划时具有一定的指导意义。

Current treatments for epilepsy can only manage the symptoms of the condition but cannot alter the initial onset or halt the progression of the disease. Consequently, it is crucial to identify drugs that can target novel cellular and molecular mechanisms and mechanisms of action. Increasing evidence suggests that axon guidance molecules play a role in the structural and functional modifications of neural networks and that the dysregulation of these molecules is associated with epilepsy susceptibility. In this review, we discuss the essential role of axon guidance molecules in neuronal activity in patients with epilepsy as well as the impact of these molecules on synaptic plasticity and brain tissue remodeling. Furthermore, we examine the relationship between axon guidance molecules and neuroinflammation, as well as the structural changes in specific brain regions that contribute to the development of epilepsy. Ample evidence indicates that axon guidance molecules, including semaphorins and ephrins, play a fundamental role in guiding axon growth and the establishment of synaptic connections. Deviations in their expression or function can disrupt neuronal connections, ultimately leading to epileptic seizures. The remodeling of neural networks is a significant characteristic of epilepsy, with axon guidance molecules playing a role in the dynamic reorganization of neural circuits. This, in turn, affects synapse formation and elimination. Dysregulation of these molecules can upset the delicate balance between excitation and inhibition within a neural network, thereby increasing the risk of overexcitation and the development of epilepsy. Inflammatory signals can regulate the expression and function of axon guidance molecules, thus influencing axonal growth, axon orientation, and synaptic plasticity. The dysregulation of neuroinflammation can intensify neuronal dysfunction and contribute to the occurrence of epilepsy. This review delves into the mechanisms associated with

本文基于气泡理论,提出了 B 类物料固相加工的流化床模型。结合已经获得的粗粒铁鳞氢还原的反应速度方程,对φ0.6米的中试装置进行了数学模拟,计算预测和实验结果相当一致。本文还采用了一些简单流化床模型对两套热试装置进行了计算预测。结果表明,对于较小的反应器,几个模型的预测结果比较接近,且与实测结果比较吻合;随着反应器尺寸的扩大,一些简单模型的计算结果偏离实验值,而本文所提模型能够适应反应器的放大。
