CropCraft: Complete Structural Characterization of Crop Plants From Images

Posted by klaurent Peking

Kavli Affiliate: Li Xin Li| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:The ability to automatically build 3D digital twins of plants from images has countless applications in agriculture, environmental science, robotics, and other fields. However, current 3D reconstruction methods fail to recover complete shapes of plants due to heavy occlusion and complex geometries. […]

Asymptotic Analysis of IMEX-RK Methods for ES-BGK Model at Navier-Stokes level

Posted by klaurent Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Implicit-explicit Runge-Kutta (IMEX-RK) time discretization methods are very popular when solving stiff kinetic equations. In [21], an asymptotic analysis shows that a specific class of high-order IMEX-RK schemes can accurately capture the Navier-Stokes limit without needing to resolve the small scales dictated […]

Cancelling mod-2 anomalies by Green-Schwarz mechanism with $B_{μν}$

Posted by dbos Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Shota Saito, Yuji Tachikawa, , , | Summary: We study if and when mod-2 anomalies can be canceled by the Green-Schwarz mechanism with the introduction of an antisymmetric tensor field $B_{munu}$. As explicit examples, we examine $SU(2)$ and more general $Sp(n)$ gauge theories in four and eight […]

Cancelling mod-2 anomalies by Green-Schwarz mechanism with $B_μν$

Posted by klaurent Tokyo

Kavli Affiliate: Yuji Tachikawa | Summary:We study if and when mod-2 anomalies can be canceled by the Green-Schwarz mechanism with the introduction of an antisymmetric tensor field $B_μν$. As explicit examples, we examine $SU(2)$ and more general $Sp(n)$ gauge theories in four and eight dimensions. We find that the mod-2 anomalies of 8d $mathcalN=1$ $Sp(n)$ […]
