Fast and Analytical EAP Approximation from a 4th-Order Tensor by Aurobrata Ghosh, Rachid Deriche

“…This method also makes the effort of computing a positive ADC worthwhile, since now both the ADC and the EAP can be used and have closed forms. We demonstrate our approach with 4th-order tensors on synthetic data and in vivo human data.…”

Calculation Method of Permeability Tensor Based on the Size Effect and Anisotropy of Rock Fracture Surface Roughness by Longyu Wang, Yanzhu Long, Gang Chen, Qianwei Mei, Fengqiang Luo, Hongsheng Gong, Ling Ma

“…Through ellipse fitting analysis, it was found that the C can be expressed in tensor form. Based on this, a new method for representing the permeability tensor is proposed by combining the roughness correction tensor and the average aperture. …”

Methods of effective media as optimal methods for modeling the physical properties of nanostructures by A. N. Yurasov, M. M. Yashin

“…The paper notes and discusses the contribution of various mechanisms that affect the physical properties of such structures, especially in the IR region of the spectrum, where the quasi-classical dimensional effect is most pronounced. The form factor of nanocomposite particles and the average particle size are such contributions that can be taken into account. …”

Characteristics and favorable area optimization of ultra-deep high-pressure basement reservoirs: A case study of Kun 2 block in Kunteyi gas reservoir, Qaidam Basin by CAO Hui, ZHANG Guoqing, XU Li, LI Zhexiang, WANG Haicheng, ZHAO Changyang, FEI Ying

“…Overall, this demonstrated tight and low-permeability characteristics. (2) The development of dissolution pores was fault-controlled, primarily distributed along Kun 1, North Kun 2, and North Kun 101 faults. These faults formed fracture-pore coupled reservoirs. The interval 100-300 m below the top of the basement was a concentrated development zone, with the maximum reservoir thickness reaching up to 200 m. (3) The innovative integration of maximum likelihood attributes and structure tensor-acoustic impedance inversion technologies achieved high-precision characterization of the spatial distribution of fractures and dissolution pores. …”

The Effect of Turbulence on the Angular Momentum of the Solar Wind by Rohit Chhiber, Arcadi V. Usmanov, William H. Matthaeus, Francesco Pecora

“…The model is restricted to the solar equatorial ( r – ϕ ) plane with axial symmetry, which permits the effect of turbulence to be expressed in analytical form as a modification to the classic E. J. Weber & L. …”
