, 2015 In solar wind, magnetohydrodynamic (MHD) discontinuities are ubiquitous and often found to be at the origin of turbulence intermittency. They may also play a key role in the turbulence dissipation and heating of the solar wind.

Application of discontinuity layout optimization to plane plasticity problems [PDF]
, 2007 A new and potentially widely applicable numerical analysis procedure for continuum mechanics problems is described. The procedure is used here to determine the critical layout of discontinuities and associated upper-bound limit load for plane plasticity ...

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Characterization of Complex Rock Mass Discontinuities from LiDAR Point Clouds
Remote SensingThe distribution and development of rock mass discontinuities in 3D space control the deformation and failure characteristics of the rock mass, which in turn affect the strength, permeability, and stability of rock masses.

利用地震光照成像法研究青藏高原东南缘岩石圈间断面结构及其动力学意义
Dizhen xuebao, 2019 为了进一步认识青藏高原东南缘的构造演化等动力学问题以及该区域的深部孕震机理，本文使用位于该区域内的中国地震科学台阵探测项目的台站所记录到的远震P波波形数据，采用地震光照成像法获取了岩石圈间断面的结构，并讨论了该方法的准确性和稳定性。研究结果显示，青藏高原东南缘的岩石圈西薄东厚，其中：滇缅泰地块腾冲火山附近最薄，约为60 km，其较薄的岩石圈可能是软流圈地幔物质上涌造成的；扬子地块岩石圈厚度从四川盆地向南逐渐减薄，特别是四川盆地下方最厚，可达190 km左右；滇缅泰地块腾冲火山下方150 ...

Treatment of discontinuities inside Earth models: Effects on computed coseismic deformations
Earth and Planetary Physics, 2021 In this paper, we study how coseismic deformations calculated in 1066 Earth models are affected by how the models treat Earth discontinuities. From the results of applying models 1066A (continuous) and 1066B (discontinuous), we find that the difference ...

The rigorous analysis of strongly coupled step discontinuities in microstrip [PDF]
, 1987 A rigorous analysis of boxed microstrip single-step discontinuities and cascades of strongly coupled discontinuities is presented. Use is made of a variational formulation involving the expansion of the transverse E field at the step in terms of suitable

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective People with epilepsy (PWE) may experience cognitive deficits but fail to undergo formal evaluation. This study compares cognitive status between PWE and healthy controls in the West African Republic of Guinea. Methods A cross‐sectional, case–control study was conducted in sequential recruitment phases (July 2024–July 2025) at Ignace ...

Evaluating Discontinuities in Complex Systems: Toward Quantitative Measures of Resilience
Ecology and Society, 2007 The textural discontinuity hypothesis (TDH) is based on the observation that animal body mass distributions exhibit discontinuities that may reflect the texture of the landscape available for exploitation.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective High‐resolution MRI enables detailed assessment of intracranial vessel wall pathology in moyamoya vasculopathy. We aimed to classify adult moyamoya vasculopathy etiologies using high‐resolution MRI and to examine subtype‐specific associations between high‐resolution MRI features and ischemic infarction.
