In a Dirac semimetal, the massless Dirac fermion has zero chirality, leading to surface states connected adiabatically to a topologically trivial surface state as well as vanishing anomalous Hall effect. Recently, it is predicted that in the nonrelativistic limit of certain collinear antiferromagnets, there exists a type of chiral“Dirac-like” fermion, whose dispersion manifests four-fold degenerate crossing points formed by spin-degenerate linear bands, with topologically protected Fermi arcs. Such an unconventional chiral fermion, protected by a hidden SU(2) symmetry in the hierarchy of an enhanced crystallographic group, namely spin space group, is not experimentally verified yet. Here, by angle-resolved photoemission spectroscopy measurements, we reveal the surface origin of the electron pocket at the Fermi surface in collinear antiferromagnet CoNb3S6. Combining with neutron diffraction and first-principles calculations, we suggest a multidomain collinear antiferromagnetic configuration, rendering the the existence of the Fermi-arc surface states induced by chiral Dirac-like *** work provides spectral evidence of the chiral Dirac-like fermion caused by particular spin symmetry in CoNb_(3)S_(6), paving an avenue for exploring new emergent phenomena in antiferromagnets with unconventional quasiparticle excitations.

为精确、快速地对煤矿用皮带输送机故障进行早期诊断,从传感器选择与布置、数据处理与融合两个方面构建了基于多传感器融合的皮带输送机故障早期诊断体系,提出了振动、温度、张力和声音4种关键监测指标。采用卡尔曼滤波法建立了数据融合的数学模型,通过实验获得了皮带输送机在不同工况下振动频率、温度变化和张力分布3种变化规律。实验结果表明,该诊断系统能够实时监测皮带输送机的运行状态,准确诊断出包括轴承磨损、电机过载和皮带松弛在内的多种故障类型,并在故障发生前平均提前24 h发出预警,显著提高了故障预警的准确性和可靠性;实验数据显示,预处理阶段未对基础数据进行显著修正,初态数据优良,T1时刻振幅感应器的原始读数2.3 mm/s经过抑噪后精简至2.2 mm/s,展示了抑噪技术在去除随机波动方面的有效性。进一步应用卡尔曼滤波后,T1时刻的数据从2.2 mm/s优化至2.18 mm/s,证明了该技术在综合不同传感信息和提高数据准确性方面的关键作用。

背景:研究发现运动者解剖结构、激素水平、神经肌肉功能等内部因素与前交叉韧带损伤风险密切相关,而运动场地材质等外部因素也成为影响非接触性前交叉韧带损伤发生的危险因素之一,但目前研究中对其关注度相对不足。目的:探讨人工草地和天然草地对青年女性跳跃落地时下肢生物力学表现影响。方法:根据测试需要将符合GB/T 20033.3-2006以及GB/T 19995.1-2005标准的人工草地和天然草地平整固定于2块三维测力台上。21名青年女性自愿受试者分别在人工草地和天然草地完成跳跃落地任务。受试者站立于台阶上随后向前跳跃,跳落至测力台后立即全力纵跳并再次落至测力台上,2次落地均要求双脚分别落至2块测力台上,整个跳跃动作流畅无停顿视为成功。同步采集下肢落地过程中运动学、动力学及肌电数据,比较分析二者差异。结果与结论:①动力学方面,在天然草地进行跳跃落地任务时初始触地时刻后向地面反作用力、纵向地面反作用力显著低于在人工草地时(P<0.05;P<0.01);峰值地面反作用力时刻二者亦显著低于在人工草地时(P<0.05;P<0.05),且表现出更高的膝关节屈曲力矩(P<0.01)。②肌电方面,在天然草地进行跳跃落地任务时初始触地时刻后100 ms内股内侧肌、股外侧肌、胫骨前肌肌电活动水平显著低于在人工草地时(P<0.05;P<0.01;P<0.05)。③结果说明,在人工草地进行跳跃落地任务时较天然草地时会出现使前交叉韧带张力升高的生物力学表现。
