Coarse graining and renormalization group in the Einstein universe [PDF]
Physical Review D, 1995 The Kadanoff-Wilson renormalization group approach for a scalar self-interacting field theor generally coupled with gravity is presented. An average potential that monitors the fluctuations of the blocked field in different scaling regimes is constructed in a nonflat background and explicitly computed within the loop-expansion approximation for an ...

Density Matrix Renormalization Group Study of Ultrasmall Superconducting Grains [PDF]
Physical Review Letters, 1999 We apply the DMRG method to the BCS pairing Hamiltonian which describes ultrasmall superconducting grains. Our version of the DMRG uses the particle (hole) states around the Fermi level as the system block (environment). We observe a smooth logarithmic-like crossover between the few electron regime and the BCS-bulk regime.

Configurational anisotropy in single-domain and pseudosingle-domain grains of magnetite [PDF]
, 2006 In classical domain theory, single-domain (SD) grains change their magnetization by coherent rotation, where the energy barrier to domain reversal is provided by the magnetocrystalline anisotropy or by shape anisotropy for elongated grains.

Interpretable and Accurate Fine-grained Recognition via Region Grouping [PDF]
2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2020 We present an interpretable deep model for fine-grained visual recognition. At the core of our method lies the integration of region-based part discovery and attribution within a deep neural network. Our model is trained using image-level object labels, and provides an interpretation of its results via the segmentation of object parts and the ...

Functional Molecular Groups on Interstellar Grains
The Astrophysical Journal, 2001 Chemical routes in the synthesis of large interstellar molecules are quite obscure, but interstellar grains are believed to play a significant role. We suggest that functional molecular groups (e.g., OH, CH, CH2, CH3, NH2, etc.) on grain surfaces may provide the precursor basis for ensuing grain chemistries that produce complex molecules.

Effect of magnetostatic interactions on the hysteresis parameters of single-domain and psuedo-single domain grains [PDF]
, 2003 From experiments it is known that magnetostatic interactions between grains strongly affect the magnetic behavior of samples. However, because of the difficulty in predicting the nonlinear behavior, the effect of interactions has been largely ignored ...

Australian Tropical Grains Germplasm Centre [PDF]
, 2010 DAQ00131 project activities aimed to: conserve tropical grains germplasm under long-term storage conditions; acquire new germplasm with unique traits of interest to clients (particularly to breeding programs); the maintenance of germplasm through ...

Attributes Grouping and Mining Hashing for Fine-Grained Image Retrieval
Proceedings of the 31st ACM International Conference on Multimedia, 2023 In recent years, hashing methods have been popular in the large-scale media search for low storage and strong representation capabilities. To describe objects with similar overall appearance but subtle differences, more and more studies focus on hashing-based fine-grained image retrieval. Existing hashing networks usually generate both local and global

Fine-grained entanglement loss along renormalization-group flows [PDF]
Physical Review A, 2005 We explore entanglement loss along renormalization group trajectories as a basic quantum information property underlying their irreversibility. This analysis is carried out for the quantum Ising chain as a transverse magnetic field is changed.

Physicochemical and Nutritional Potential of Fifteen Sorghum Cultivars from Burkina Faso
Agriculture, 2023 (1) Background: Sorghum (Sorghum bicolor (L.) Moench) is a staple food cereal for most of the rural populations in sub-Saharan Africa. In Burkina Faso, a great diversity of sorghum cultivar is cultivated, but its nutritional potential still needs to be ...
