Strong stability and strong quasistability of vector trajectorial problem of lexicographic optimization [PDF]
Computer Science Journal of Moldova, 1998 Two types of stability of the lexicographic set for the multicriteria problem on a system of subsets of a finite set with the vector criterion of the most general kind are investigated.

Congenital Malformations in the Moroccan Surveillance System: Contribution to Prevalence Estimation. [PDF]
Glob Health Epidemiol GenomBackground. Congenital malformations (CMs) are a group of structural or functional anomalies present at birth. These anomalies result in a high rate of mortality, morbidity, and disability in children. CMs are a major public health problem and place a heavy burden on healthcare systems in both developed and developing countries including Morocco, which

Quasistates and quasiprobabilities [PDF]
Physical Review A, 2018 The quasiprobability representation of quantum states addresses two main concerns, the identification of nonclassical features and the decomposition of the density operator. While the former aspect is a main focus of current research, the latter decomposition property has been studied less frequently. In this contribution, we introduce a method for the

Polynomial‐time universality and limitations of deep learning
Communications on Pure and Applied Mathematics, Volume 76, Issue 11, Page 3493-3549, November 2023., 2023 Abstract The goal of this paper is to characterize function distributions that general neural networks trained by descent algorithms (GD/SGD), can or cannot learn in polytime. The results are: (1) The paradigm of general neural networks trained by SGD is poly‐time universal: any function distribution that can be learned from samples in polytime can ...

Human Brain Mapping, Volume 44, Issue 6, Page 2158-2175, April 15, 2023., 2023 We highlight the replicable time‐resolved developmental and aging functional brain patterns in a systematic evaluation of over 47,000 youth and adult brains. Our study captured the most contrastive difference between the two life stages in a brain state that indicated coherent strengthening and modularization of functional coupling within the auditory,

Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023 Considering that the effect of solar radiation on the super‐high arch dam temperature field remains poorly studied, the calculation accuracy of dam temperature deformation is unable to be guaranteed accordingly. To address the issue, the solar radiation effect is adequately taken into consideration by proposing a practical calculation method based on ...
