《作为社会棱镜的音乐》一文已经提到,阿多诺在思想与论述中都是有意识地拒绝体系化表达的。对他来说,无论人文、艺术还是科学,其真正目的都在于对人类的意识能力进行提升,而如若把某些预先制定好的体系与原则从外部施加于我们所要认识的事物上,则无异于是在抹除事物自身的独特属性以及事物之间的微妙差异,那么也就是在伤害人类的意识能力。所以,阿多诺要求音乐不能仅仅是被动地接受并施用素材(其中包括体系、手法、风格等)。

Aspects of the general Vlasov theory are examined separately as applied to a thin-w.lled channel section cantilever beam under free-end end loading. In particular, the flexural bending and shear that arise under transverse shear and axial torsional loading are each considered theoretically. These analyses involve the location of the shear centre at w.ich transverse shear forces w.en applied do not produce torsion. This centre, w.en taken to be coincident w.th the centre of tw.st implies an equivalent reciprocal behaviour. That is, an axial torsion applied concentric w.th the shear centre w.ll tw.st but not bend the beam. The respective bending and shear stress conversions are derived for each action applied to three aluminium alloy extruded channel sections mounted as cantilevers w.th a horizontal principal axis of symmetry. Bending and shear are considered more generally for other thin-w.lled sections w.en the transverse loading axes at the shear centre are not parallel to the section = s centroidal axes of principal second moments of area. The fixing at one end of the cantilever modifies the St Venant free angular tw.st and the free w.rping displacement. It is show. from the w.gner-Kappus torsion theory how.the end constrained w.rping generates an axial stress distribution that varies w.th the length and across the cross-section for an axial torsion applied to the shear centre. It should be mentioned here for w.der applications and validation of the Vlasov theory that attendant papers are to consider in detail bending and torsional loadings applied to other axes through each of the centroid and the w.b centre. Therein, both bending and tw.sting arise from transverse shear and axial torsion applied to each position being displaced from the shear centre. Here, the influence of the axis position upon the net axial and shear stress distributions is to be established. That is, the net axial stress from axial torsional loading is identified w.th the sum of axial stress

This study examines the effectiveness of adaptive observation experiments using the ensemble transformation sensitivity (ETS) method to improve precipitation forecasts during heavy rainfall events in South China and the Sichuan Basin. High-resolution numerical models are employed to simulate adaptive observations. By identifying the sensitive areas of key w.ather system positions 42 hours before heavy rainfall events, the adaptive observations improve the prediction of jet streams, strong w.nds, and shear lines, w.ich are essential for accurate heavy rainfall forecasting. This improvement is reflected in both the precipitation structure and location accuracy w.thin the verification region. In South China, targeted observations enhance rainfall predictions by improving w.ter vapor transport. In the Sichuan Basin, adaptive observations refine w.ter vapor transport and adjust vortex dynamics. This research highlights the importance of accurately predicting shear lines and jet streams for forecasting heavy rainfall in these areas. Overall, this study found that adaptive observation enhances the precipitation forecast skills of the structure and location for heavy rainfall in South China and the Sichuan Basin, emphasizing their potential utility in operational numerical w.ather prediction. © Institute of Atmospheric Physics/Chinese Academy of Sciences, and Science Press 2024.

Background: In recent years, online trolling has garnered significant attention due to its detrimental effects on mental health and social w.ll-being. The current study examined the influence of peer victimization on adolescent online trolling behavior, proposing that hostile attribution bias mediated this relationship and that trait mindfulness moderated both the direct and indirect effects. Methods: A total of 833 Chinese adolescents completed the measurements of peer victimization, hostile attribution bias, trait mindfulness, and online trolling. Moderated mediation analysis w.s performed to examine the relationships betw.en these variables. Results: After controlling for gender and residential address, the study found a significant positive correlation betw.en peer victimization and online trolling, w.th hostile attribution bias serving as a mediator. In addition, trait mindfulness moderated the direct relationship betw.en peer victimization and online trolling. Specifically, the effect of peer victimization on online trolling w.s attenuated w.en adolescents had high levels of trait mindfulness. The results of the study emphasized the joint role of peer and personal factors in adolescents’ online trolling behavior and provide certain strategies for intervening in adolescents’ online trolling behavior. Conclusion: The results of the study suggest that strategies focusing on peer support and mindfulness training can have a positive impact on reducing online trolling behavior, promoting adolescents’ mental health, and their long-term development. © 2024 The Authors.

It has recently been show. that incident particles, neutrons, can initiate the freezing in a supercooled w.ter volume. This new.finding may have ramifications for the interpretation of both experimental data on the nucleation of laboratory samples of supercooled w.ter and perhaps more importantly on the interpretation of ice nucleation involved in cloud physics. For example, if some fraction of the cloud nucleation previously attributed to dust, soot, or aerosols has been caused by cosmogenic neutrons, fresh consideration is required in the context of climate models. Moreover, as cosmogenic neutrons, most being muon-induced, have much greater flux at high latitudes, estimates of ice nucleates in these regions may be larger than required to accurately model cloud and condensation properties. This discrepancy has been pointed out in IPCC reports. Our paper discusses the connection betw.en the new.concept of neutrons nucleating supercooled w.ter and the need for a new.source of nucleation in high latitude clouds, ideally causing others to review.current data, or to analyse future data w.th this idea in mind. .

Background: Epidural anesthesia is an effective intervention to treat labor pain and provide analgesia for orthopedic procedures. A rare complication of this technique is epidural catheter retention. Case Presentation: In this case report, w. present an otherw.se healthy 21-year-old G2P0010 w.man at 39 w.eks and 3 days gestation w.ose anesthetic management w.s complicated by a symptomatic retained epidural catheter fragment. Computed tomography (CT) imaging of her spine show.d the fractured catheter w.thin her paraspinal muscles and neurosurgery recommended no surgical intervention at that time. The patient reported resolution of back pain w.ile in the postpartum unit w.ich she continues to endorse tw. w.eks after discharge. Conclusion: Retained epidural catheter is a medical emergency that requires immediate imaging and neurological evaluation. w.ile magnetic resonance imaging is typically regarded as the standard imaging modality for this complication, in epidural sets that contain metallic components, w. suggest using CT to avoid the risk of thermal nerve damage. In cases w.ere the patient does not report any acute complaints, nonsurgical management may be appropriate but close follow.up is required to monitor for catheter migration.
